entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and
delivered to the Trustee or (2) notification to the Trustee that the Trustee shall serve as
Registrar or Paying Agent until the appointment of a successor in accordance with clause (1) above.
The Registrar or Paying Agent may resign at any time upon written notice; provided, however, that
the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in
accordance with Section 7.08.



     SECTION 2.06 Paying Agent to Hold Money in Trust. Prior to each due date of the principal
and interest on any Debenture, the Company shall deposit with the Paying Agent (or if the Company
or a Subsidiary is acting as Paying Agent, segregate and hold in trust for the benefit of the
Persons entitled thereto) a sum sufficient to pay such principal and interest when so becoming due.
The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the
Paying Agent shall hold in trust for the benefit of Debentureholders or the Trustee all money held

the Trustee of any default by the Company in making any such payment. If the Company or a
Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as Paying

delivered to the Trustee.



     SECTION 2.07 Debentureholder Lists. The Trustee shall preserve in as current a form as is

Debentureholders. If the Trustee is not the Registrar, the Company shall furnish, or cause the
Registrar to furnish, to the Trustee, in writing at least five Business Days before each interest
payment date and at such other times as the Trustee may request in writing, a list in such form and

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

agency maintained by the Company pursuant to Section 4.02. Whenever any Debentures are so
surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Debentures that the Holder making the exchange is entitled to receive bearing
registration numbers not contemporaneously outstanding.



     All Debentures issued upon any registration of transfer or exchange of Debentures shall be the

     (ii) Notwithstanding any other provision in this Indenture, no Global Debenture may be
exchanged in whole or in part for Debentures registered, and no transfer of a Global
Debenture in whole or in part may be registered, in the name of any Person other than the

to continue as Depositary for such Global Debenture or (y) has ceased to be a
clearing agency registered under the Exchange Act, and a successor depositary has

rights under the Debentures or this Indenture, including its rights following the occurrence

Debentures for the Depositary or its nominee with respect to such Global Debentures, shall
reduce the principal amount thereof, by an amount equal to the portion thereof to be so
exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon
any such surrender or adjustment, the Trustee shall authenticate and make available for
delivery the Debentures issuable on such exchange to or upon the written order of the
Depositary or an authorized representative thereof.

owner and Holder of such Global Debentures for all purposes whatsoever. Notwithstanding the
foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company
or the Trustee from giving effect to any written certification, proxy or other authorization
furnished by the Depositary or such nominee, as the case may be, or impair, as between the
Depositary, its Agent Members and any other Person on whose behalf an Agent Member may act,

a Holder of any Debentures.




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



     (c) Every Debenture (and all securities issued in exchange therefor or in substitution
thereof) that bears or is required under this Section 2.08(c) to bear the legend set forth in this
Section 2.08(c) (together with any Common Stock issued upon conversion of the Debentures and
required to bear the legend set forth in Exhibit B, collectively, the “Restricted
Securities”) shall



16









 







be subject to the restrictions on transfer set forth in this Section 2.08(c) (including those
set forth in the legend below and the legend set forth in Exhibit B) unless such
restrictions on transfer shall be waived by written consent of the Company following receipt of
legal advice supporting the permissibility of the waiver of such transfer restrictions, and the
holder of each such Restricted Security, by such holder’s acceptance thereof, agrees to be bound by
all such restrictions on transfer. As used in this Section 2.08(c), the term “transfer” means any
sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any
interest therein.



     Until the expiration of the holding period applicable to sales of Restricted Securities under
Rule 144(k) under the Securities Act (or any successor provision), any certificate evidencing a
Restricted Security shall bear a legend in substantially the following form (or as set forth in
Exhibit B, in the case of Common Stock issued upon conversion of the Debentures), unless
such Restricted Security has been sold pursuant to a registration statement that has been declared
effective under the Securities Act (and which continues to be effective at the time of such
transfer) or sold pursuant to Rule 144 under the Securities Act or any similar provision then in
force, or unless otherwise agreed by the Company in writing as set forth above, with written notice
thereof to the Trustee:




     THE SECURITY EVIDENCED BY THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED (THE “SECURITIES ACT OF 1933”), OR ANY STATE SECURITIES LAWS, AND
MAY NOT BE OFFERED OR SOLD EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE. BY ACQUISITION
HEREOF OR A BENEFICIAL INTEREST HEREIN, THE HOLDER:




     (1) REPRESENTS THAT IT IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A
UNDER THE SECURITIES ACT OF 1933;




     (2) AGREES THAT IT WILL NOT PRIOR TO THE DATE TWO YEARS AFTER THE DATE OF ORIGINAL
ISSUANCE OF THE 3.00% SENIOR CONVERTIBLE DEBENTURES DUE 2027 OF TRICO MARINE SERVICES, INC.
(THE “COMPANY”) RESELL OR OTHERWISE TRANSFER THE SECURITY EVIDENCED HEREBY OR THE COMMON
STOCK THAT MAY BE ISSUABLE UPON CONVERSION OF SUCH SECURITY EXCEPT (A) TO THE COMPANY OR ANY
SUBSIDIARY THEREOF, (B) TO A PERSON IT REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL
BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT OF 1933, (C) PURSUANT TO A
REGISTRATION STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT OF 1933
AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH TRANSFER, OR (D) PURSUANT TO ANY
OTHER EXEMPTION FROM REGISTRATION REQUIREMENTS UNDER THE SECURITIES ACT OF 1933, INCLUDING
UNDER RULE 144 , IF AVAILABLE, SUBJECT TO THE COMPANY’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY
SUCH TRANSFER, TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATIONS AND/OR OTHER
INFORMATION SATISFACTORY TO THE COMPANY AND THE TRUSTEE; AND



17









 






     (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THE SECURITY EVIDENCED HEREBY IS
TRANSFERRED (OTHER THAN A TRANSFER PURSUANT TO CLAUSE 2(A) AND 2(C) ABOVE) A NOTICE
SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.



     In connection with any transfer of the Debentures prior to the date two years after the last
date of original issuance of the Debentures (other than a transfer pursuant to clause 2(C) above),
the Holder must complete and deliver the transfer certificate contained in this Indenture to the
Trustee (or any successor Trustee, as applicable). If the proposed transfer is pursuant to clause
2(D) above, the Holder must, prior to such transfer, furnish to the Trustee (or any successor
Trustee, as applicable), such certifications, legal opinions or other information as the Company
may reasonably require to confirm that such transfer is being made pursuant to an exemption from,
or in a transaction not subject to, the registration requirements of the Securities Act. The legend
set forth above will be removed upon the earlier of the transfer of the Debentures evidenced
thereby pursuant to clause 2(C) above or the expiration of two years from the last date of original
issuance of the Debentures.



     Any Debentures that are Restricted Securities and as to which such restrictions on transfer
shall have expired in accordance with their terms or as to conditions for removal of the foregoing
legend set forth therein have been satisfied may, upon surrender of such Debentures for exchange to
the Registrar in accordance with the provisions of this Section 2.08, be exchanged for a new
Debenture or Debentures, of like tenor and aggregate principal amount, which shall not bear the
restrictive legend required by this Section 2.08(c). If such Restricted Security surrendered for
exchange is represented by a Global Debenture bearing the legend set forth in this Section 2.08(c),
the principal amount of the legended Global Debentures shall be reduced by the appropriate
principal amount and the principal amount of a Global Debenture without the legend set forth in
this Section 2.08(c) shall be increased by an equal principal amount. If a Global Debenture without
the legend set forth in this Section 2.08(c) is not then outstanding, the Company shall execute and
the Trustee shall authenticate and deliver an unlegended Global Debentures to the Depositary.



     In the event Rule 144(k) as promulgated under the Securities Act is amended to change the
two-year period under Rule 144(k), then, the references in the restrictive legend set forth above
to “two years,” and in the corresponding transfer restrictions described above included in this
Indenture and the Debentures and with respect to shares of the Common Stock will be deemed to refer
to such changed period, from and after receipt by the Trustee of an Officers’ Certificate and
Opinion of Counsel evidencing such changes. However, such changes will not be made if they are
otherwise prohibited by, or would otherwise cause a violation of, the federal securities laws
applicable at the time. As soon as practicable after the Company knows of the effectiveness of any
such amendment to change the two-year period under Rule 144(k), unless such changes would otherwise
be prohibited by, or would otherwise cause a violation of, the federal securities laws applicable
at the time, the Company will provide to the Trustee an Officers’ Certificate and Opinion of
Counsel evidencing such changes as to the effectiveness of such amendment and the effectiveness of
such change to the restrictive legends and transfer restrictions.



18









 





     (d) Any Restricted Securities, prior to the expiration of the holding period applicable to
sales thereof under Rule 144(k) under the Securities Act (or any successor provision), purchased or
owned by the Company or any Affiliate thereof may not be resold by the Company or such Affiliate
unless registered under the Securities Act or resold pursuant to an exemption from the registration
requirements of the Securities Act in a transaction which results in such Debentures or Common
Stock, as the case may be, no longer being “restricted securities” (as defined under Rule 144).



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



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



     SECTION 2.09 Replacement Debentures
.. If a mutilated Debenture is surrendered to the Registrar or if the Debentureholder of a Debenture
claims that the Debenture has been lost, destroyed or wrongfully taken, the Company shall issue and
the Trustee shall authenticate a replacement Debenture if the requirements of Section 8-405 of the
Uniform Commercial Code are met, such that the Debentureholder (i) satisfies the Company and the
Trustee within a reasonable time after he has notice of such loss, destruction or wrongful taking
and the Registrar does not register a transfer prior to receiving such notification, (ii) makes
such request to the Company and the Trustee prior to the Debenture being acquired by a protected
purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected purchaser”) and
(iii) satisfies any other reasonable requirements of the Trustee and the Company. If required by
the Trustee or the Company, such Debentureholder shall furnish an indemnity bond sufficient in the
judgment of the Trustee to protect the Company, the Trustee, the Paying Agent and the Registrar
from any loss that any of them may suffer if a Debenture is replaced. The Company and the Trustee
may charge the Debentureholder for their expenses in replacing a Debenture. In case any Debenture
which has matured or is about to mature or has been called for redemption or has been properly
tendered for repurchase on a
Fundamental Change Repurchase Date (and not withdrawn) or has been tendered for repurchase on a
Repurchase Date (and not withdrawn), as



19









 







the case may be, or is to be converted into Common Stock,
shall become mutilated or be destroyed, lost or wrongfully taken, the Company may, instead of
issuing a substitute Debenture, pay or authorize the payment of or convert or authorize the
conversion of the same (without surrender thereof except in the case of a mutilated Debenture), as
the case may be, if the applicant for such payment or conversion shall furnish to the Company, to
the Trustee and, if applicable, to such authenticating agent such security or indemnity as may be
required by them to save each of them harmless for any loss, liability, cost or expense caused by
or in connection with such substitution, and, in every case of destruction, loss or wrongful
taking, the applicant shall also furnish to the Company, the Trustee and, if applicable, any Paying
Agent or conversion agent evidence to their satisfaction of the destruction, loss or wrongful
taking of such Debentures and of the ownership thereof.



     Every replacement Debenture is an additional obligation of the Company.



     The provisions of this Section 2.09 are exclusive and shall preclude (to the extent lawful)
all other rights and remedies with respect to the replacement or payment of mutilated, lost,
destroyed or wrongfully taken Debentures.



     SECTION 2.10 Outstanding Debentures
.. Debentures outstanding at any time are all Debentures authenticated by the Trustee except for
those canceled by it, those delivered to it for cancellation and those described in this Section as
not outstanding. A Debenture does not cease to be outstanding because the Company or an Affiliate
of the Company holds the Debenture.



     If a Debenture is replaced pursuant to Section 2.09, it ceases to be outstanding unless the
Trustee and the Company receive proof satisfactory to them that the replaced Debenture is held by a
protected purchaser.



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



     SECTION 2.11 Temporary Debentures
.. Pending the preparation of Debentures in certificated form, the Company may execute and the
Trustee or an authenticating agent appointed by the Trustee shall, upon the written request of the
Company, authenticate and deliver temporary Debentures (printed or lithographed). Temporary
Debentures shall be issuable in any authorized denomination, and substantially in the form of the
Debentures in certificated form, but with such omissions, insertions and variations as may be
appropriate for temporary Debentures, all as may be determined by the Company. Every such temporary
Debentures shall be executed by the Company and authenticated by the Trustee or such authenticating
agent upon the same conditions and in substantially the same manner, and
with the same effect, as the Debentures in certificated form. Without unreasonable delay, the
Company will execute and deliver to the Trustee or such authenticating agent Debentures in
certificated form and thereupon



20









 







any or all temporary Debentures may be surrendered in exchange
therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the
Trustee or such authenticating agent shall authenticate and make available for delivery in exchange
for such temporary Debentures an equal aggregate principal amount of Debentures in certificated
form. Such exchange shall be made by the Company at its own expense and without any charge
therefor. Until so exchanged, the temporary Debentures shall in all respects be entitled to the
same benefits and subject to the same limitations under this Indenture as Debentures in
certificated form authenticated and delivered hereunder.



     SECTION 2.12 Cancellation. The Company at any time may deliver Debentures to the Trustee for cancellation. The Registrar and
the Paying Agent shall forward to the Trustee any Debentures surrendered to them for registration
of transfer, exchange or payment. The Trustee and no one else shall cancel all Debentures
surrendered for registration of transfer, exchange, payment or cancellation and dispose of such
canceled Debentures in accordance with its customary procedures or deliver canceled Debentures to
the Company. The Company may not issue new Debentures to replace Debentures it has redeemed, paid
or delivered to the Trustee for cancellation. The Trustee shall not authenticate Debentures in
place of canceled Debentures other than pursuant to the terms of this Indenture.



     SECTION 2.13 CUSIP and ISIN Numbers. The Company in issuing the Debentures may use “CUSIP” and “ISIN” numbers (if then generally in
use) and, if so, the Trustee shall use “CUSIP” and “ISIN” numbers in notices of redemption as a
convenience to Debentureholders; provided, however, that any such notice may state that no
representation is made as to the correctness of such numbers either as printed on the Debentures or
as contained in any notice of a redemption and that reliance may be placed only on the other
identification numbers printed on the Debentures, and any such redemption shall not be affected by
any defect in or omission of such numbers. The Company shall promptly notify the Trustee in writing
of any changes to the CUSIP and ISIN numbers.



SECTION 2.14 Additional Debentures. The Company may, from time to time, subject to compliance with any other applicable provisions of
this Indenture, without the consent of the Debentureholders, create and issue pursuant to this
Indenture additional Debentures (“Additional Debentures”) having terms and conditions set forth in
Exhibit A identical to those of the other outstanding Debentures, except that Additional
Debentures may:




     (1) have a different issue price than other outstanding Debentures;



     (2) have a different Issue Date from the Issue Date for other outstanding Debentures;



     (3) have a different amount of interest payable on the first interest payment date after
issuance than is payable on other outstanding Debentures;



     (4) have terms specified in the Additional Debentures Board Resolutions for such Additional
Debentures making appropriate adjustments to this Article 2 and Exhibit A (and related
definitions) applicable to such Additional Debentures in order to conform to and ensure compliance
with the Securities Act (or other applicable securities laws) and any registration rights or
similar agreement applicable to such Additional Debentures, which are not adverse in



21









 







any material
respect to the Holder of any outstanding Debentures (other than such Additional Debentures); and



     (5) be entitled to additional interest or other liquidated damages specified in a registration
rights agreement not applicable to other outstanding Debentures and not be entitled to such
additional interest or other liquidated damages applicable to other outstanding Debentures;


provided, that no adjustment pursuant to this Section 2.14 shall cause such Additional Debentures
to constitute, as determined pursuant to an Opinion of Counsel, a different class of securities
than the Debentures issued pursuant to the Purchase Agreement for U.S. federal income tax purposes;
and provided further, that the Additional Debentures have the same CUSIP number as other
outstanding Debentures. No Additional Debentures may be issued if on the Issue Date therefor any
Event of Default has occurred and is continuing.



The Debentures originally issued pursuant to the Purchase Agreement and any Additional Debentures
shall be treated as a single class for all purposes under this Indenture, including waivers,
amendments, redemptions, offers to purchase and United States federal tax purposes.




     With respect to any issuance of Additional Debentures, the Company shall deliver to the
Trustee a resolution of the Board of Directors and an Officers’ Certificate in respect of such
Additional Debentures, which shall together provide the following information:




     (1) the aggregate principal amount of such Additional Debentures to be authenticated
and delivered pursuant to this Indenture;




     (2) the Issue Date, issue price, pre-issuance accrued interest, amount of interest
payable on the first interest payment date, first interest payment date, CUSIP number and
corresponding ISIN of such Additional Debentures; and




     (3) such matters as shall be applicable to such Additional Debentures as described in
clauses (4) and (5) of the preceding paragraph



ARTICLE 3

REDEMPTION AND REPURCHASE OF DEBENTURES




SECTION 3.01 Optional Redemption of Debentures. At any time on or after January 15, 2012, the Debentures may be redeemed at the option of the
Company, in whole or in part from time to time, upon notice as set forth in Section 3.02, in cash
at the redemption price set forth below. In addition, the Company will pay interest on the
Debentures being redeemed, which interest will include such interest accrued and unpaid to, but
excluding, the redemption date; provided, that if the redemption date is after a Record Date and on
or prior to the corresponding interest payment date, the interest will be paid on the redemption
date to the holder of record on the Record Date. The Company may not redeem any Debentures if a
Default in the payment of interest on the Debentures has occurred and is continuing.




22









 








     The redemption price for the Debentures, expressed as a percentage of principal amount, is as
follows for the periods set forth below:



	 	 	 	 	 
	 	 	Redemption
	Period	 	Price
	January 15, 2012 through January 14, 2013
	 	 	100.8571	%
	January 15, 2013 through January 14, 2014
	 	 	100.4286	%
	After January 14, 2014
	 	 	100.0000	%






     SECTION 3.02 Notice of Optional Redemption; Selection of Debentures to be Redeemed
.. In case the Company shall desire to exercise the right to redeem all or, as the case may be, any
part of the Debentures pursuant to Section 3.01, it shall fix a date for redemption and it or, at
its written request received by the Trustee not fewer than five Business Days prior (or such
shorter period of time as may be acceptable to the Trustee) to the date the notice of redemption is
to be mailed, the Trustee in the name of and at the expense of the Company, shall mail or cause to
be mailed a notice of such redemption not fewer than 30 calendar days nor more than 60 calendar
days prior to the redemption date to each Holder of Debentures so to be redeemed in whole or in
part at its last address as the same appears on the Register; provided that if the Company makes
such request of the Trustee, it shall, together with such request, also give written notice of the
redemption date to the Trustee, provided that the text of the notice shall be prepared by the
Company. Such mailing shall be by first class mail. The notice, if mailed in the manner herein
provided, shall be conclusively presumed to have been duly given, whether or not the Holder
receives such notice. In any case, failure to give such notice by mail or any defect in the notice
to the Holder of any Debentures designated for redemption as a whole or in part shall not affect
the validity of the proceedings for the redemption of any other Debentures.



     Each such notice of redemption shall specify: (i) the aggregate principal amount of Debentures
to be redeemed, (ii) the CUSIP number or numbers of the Debentures being redeemed, (iii) the date
fixed for redemption (which shall be a Business Day), (iv) the redemption price at which Debentures
are to be redeemed, (v) the place or places of payment and that payment will be made upon
presentation and surrender of such Debentures, (iv) that interest accrued and unpaid to, but
excluding, the date fixed for redemption will be paid as specified in said notice, and that on and
after said date interest thereon or on the portion thereof to be redeemed will cease to accrue,
(vii) that the Holder has a right to convert the Debentures called for redemption, (viii) the
Conversion Rate on the date of such notice, (ix) the time and date on which the right to convert
such Debentures or portions thereof will expire, and (x) the date on which the Conversion
Settlement Averaging Period begins. If fewer than all the Debentures are
to be redeemed, the notice of redemption shall identify the Debentures to be redeemed
(including CUSIP numbers, if any). In case any Debentures are to be redeemed in part only, the
notice of redemption shall state the portion of the principal amount thereof to be redeemed and
shall state that, on and after the redemption date, upon surrender of such Debentures, a new
Debentures or Debentures in principal amount equal to the unredeemed portion thereof will be
issued.



23









 





     Whenever any Debentures are to be redeemed, the Company will give the Trustee written notice
of the redemption date, together with an Officers’ Certificate as to the aggregate principal amount
of Debentures to be redeemed not fewer than 35 calendar days (or such shorter period of time as may
be acceptable to the Trustee) prior to the redemption date.



     On or prior to the redemption date specified in the notice of redemption given as provided in
this Section 3.02, the Company will deposit with the Paying Agent (or, if the Company is acting as
its own Paying Agent, set aside, segregate and hold in trust as provided in Section 2.06) an amount
of money in immediately available funds sufficient to redeem on the redemption date all the
Debentures (or portions thereof) so called for redemption (other than those theretofore surrendered
for conversion) at the appropriate redemption price, together with accrued and unpaid interest to,
but excluding, the redemption date; provided that if such payment is made on the redemption date,
it must be received by the Paying Agent, by 11:00 a.m., New York City time, on such date. If any
Debentures called for redemption are converted pursuant hereto prior to such redemption date, any
money deposited with the Paying Agent or so segregated and held in trust for the redemption of such
Debentures shall be paid to the Company or, if then held by the Company, shall be discharged from
such trust.



     If less than all of the outstanding Debentures are to be redeemed, the Trustee shall select
the Debentures or portions thereof of the Global Debentures or the Debenture in certificated form
to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or
by another method the Trustee deems fair and appropriate. If any Debenture selected for redemption
is submitted for conversion in part after such selection, the portion of such Debenture submitted
for conversion shall be deemed (so far as may be possible) to be the portion to be selected for
redemption. The Debentures (or portions thereof) so selected for redemption shall be deemed duly
selected for redemption for all purposes hereof, notwithstanding that any such Debentures are
submitted for conversion in part before the mailing of the notice of redemption.



     Upon any redemption of less than all of the outstanding Debentures, the Company and the
Trustee may (but need not), solely for purposes of determining the pro rata allocation among such
Debentures that are unconverted and outstanding at the time of redemption, treat as outstanding any
Debentures surrendered for conversion during the period of fifteen calendar days preceding the
mailing of a notice of redemption and may (but need not) treat as outstanding any Debentures
authenticated and delivered during such period in exchange for the unconverted portion of any
Debentures converted in part during such period.



     SECTION 3.03 Payment of Debentures Called for Redemption
.. If notice of redemption has been given as provided in Section 3.02, the Debentures or portion of
Debentures with respect to which such notice has been given shall, unless converted pursuant to the
terms hereof, become due and payable on the date fixed for redemption and at the place or
places stated in such notice at the redemption price, plus interest accrued and unpaid to, but
excluding, the redemption date (unless the redemption date is after a Record Date and on or prior
to the corresponding interest payment date, in which event the interest will be paid on the
interest payment date to the holder of record on the Record Date), and, unless the Company shall
default in the payment of such Debentures at the redemption price, plus interest, if any, accrued
and unpaid to, but excluding, such date, interest on the Debentures or portion of Debentures so
called for redemption, interest shall cease to accrue on and after such date and, after 5:00 p.m.,
New



24









 







York City time, on the Business Day immediately preceding the redemption date (unless the
Company shall default in the payment of such Debentures at the redemption price, together with
interest accrued to such date), such Debentures shall cease to be convertible and, except as
provided in Section 2.06 and Section 8.02, to be entitled to any benefit or security under this
Indenture, and the Holders thereof shall have no right in respect of such Debentures except the
right to receive the redemption price thereof plus, if applicable, accrued and unpaid interest to,
but excluding, the redemption date. On presentation and surrender of such Debentures at a place of
payment in said notice specified, the said Debentures or the specified portions thereof shall be
paid and redeemed by the Company at the redemption price, together with interest accrued and unpaid
thereon to, but excluding, the redemption date; provided that if the applicable redemption date is
after the applicable Record Date and on or before an interest payment date, the interest payable on
such interest payment date shall be paid on such interest payment date to the Holders of record of
such Debentures on the applicable Record Date instead of the Holders surrendering such Debentures
for redemption on such date.



     Upon presentation of any Debentures redeemed in part only, the Company shall execute and the
Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of
the Company, a new Debenture or Debentures, of authorized denominations, in principal amount equal
to the unredeemed portion of the Debentures so presented.



     Notwithstanding the foregoing, the Trustee shall not redeem any Debentures or mail any notice
of redemption during the continuance of a Default in payment of interest on the Debentures. If any
Debentures called for redemption shall not be so paid upon surrender thereof for redemption on the
redemption date as provided in this Section 3.03, to the extent legally permissible, the redemption
price shall, until paid or duly provided for, bear interest from and including the redemption date
at the rate borne by the Debentures and such Debentures shall remain convertible into Common Stock
until the redemption price and interest shall have been paid or duly provided for.



     SECTION 3.04 Repurchase at Option of Holders Upon a Fundamental Change
.. (a) If there shall occur a Fundamental Change at any time prior to maturity of the Debentures,
then each Holder of Debentures shall have the right, at such Holder’s option, to require the
Company to repurchase all of such Holder’s Debentures, or any portion thereof that is a multiple of
$1,000 principal amount, on a date (the “Fundamental Change Repurchase Date”) specified by the
Company, that is not less than 20 calendar days nor more than 35 calendar days after the date of
the Company Repurchase Notice related to such Fundamental Change at a cash repurchase price equal
to 100% of the principal amount of the Debentures being repurchased, plus accrued and unpaid
interest to, but excluding, the Fundamental Change Repurchase Date, subject to the satisfaction by
the Holder of the requirements set forth in Section 3.04(c); provided
that if such Fundamental Change Repurchase Date falls after a Record Date and on or prior to the
corresponding interest payment date, then the interest payable on such interest payment date shall
be paid on such interest payment date to the Holders of record of the Debentures on the applicable
Record Date instead of the Holders surrendering the Debentures for repurchase on such date.



     (b) On or before the fifth Business Day after the occurrence of a Fundamental Change, the
Company shall mail or deliver or cause to be mailed or delivered to all Holders of



25









 







record of the
Debentures on the date of the Fundamental Change at their addresses shown in the Register (and to
beneficial owners of the Debentures as required by applicable law) a Company Repurchase Notice as
set forth in Section 3.06 with respect to such Fundamental Change. The Company shall also deliver a
copy of the Company Repurchase Notice to the Trustee and the Paying Agent at such time as it is
mailed to Holders of Debentures.



     No failure of the Company to give the foregoing notices and no defect therein shall limit the
repurchase rights of Holders of Debentures or affect the validity of the proceedings for the
repurchase of the Debentures pursuant to this Section 3.04.



     (c) For Debentures to be repurchased at the option of the Holder, the Holder must deliver to
the Paying Agent, prior to 5:00 p.m., New York City time, on the Fundamental Change Repurchase
Date, (i) a written notice of repurchase (the “Repurchase Notice”) in the form set forth on the
reverse of the Debentures duly completed (if the Debentures are certificated) or stating the
following (if the Debentures are represented by a Global Debenture): (A) the certificate number of
the Debentures which the Holder will deliver to be repurchased or compliance with the appropriate
Depositary procedures, (B) the portion of the principal amount of the Debentures which the Holder
will deliver to be repurchased, which portion must be in principal amounts of $1,000 or an integral

provided, however, that such repurchase price shall be so paid pursuant to this Section 3.04 only
if the Debentures so delivered to the Paying Agent shall conform in all respects to the description
thereof in the Repurchase Notice. All questions as to the validity, eligibility (including time of
receipt) and acceptance of any Debentures for repurchase shall be determined by the Company, whose
determination shall be final and binding absent manifest error.



     (d) The Company shall repurchase from the Holder thereof, pursuant to this Section 3.04, a

“Repurchase Date”), at a repurchase price of 100% of the principal amount of the Debentures being
repurchased, plus accrued and unpaid interest to, but excluding, the Repurchase Date, provided that
if such Repurchase Date falls after a Record Date and on or prior to the corresponding interest
payment date, then the interest payable on such interest payment date shall be paid on such
interest payment date to the Holders of record of the Debentures on the applicable Record Date
instead of the Holders surrendering the Debentures for repurchase on such date.



     (b) On or before the twentieth Business Day prior to each Repurchase Date, the Company shall
mail or cause to be mailed to all Holders of record on such date (and to beneficial owners as

to the Paying Agent, at any time during the period beginning at 9:00 a.m., New York City time, on

certificate number of the Debentures which the Holder will deliver to be repurchased or compliance
with the appropriate Depositary procedures, (B) the portion of the principal amount of the
Debentures which the Holder will deliver to be repurchased, which portion must be in principal
amounts of $1,000 or an integral multiple of $1,000, and (C) that such Debentures shall be
repurchased by the Company pursuant to the terms and conditions specified in the Debentures and in
this Indenture, together with (ii) such Debentures duly endorsed for transfer (if the Debentures
are certificated) or book-entry transfer of such Debentures (if such Debentures are represented by
a Global Debenture). The delivery of such Debentures to the Paying Agent (together with all
necessary endorsements) at the office of the Paying Agent shall be a condition to the receipt by
the Holder of the repurchase price therefore; provided, however, that such repurchase price shall
be so paid pursuant to this Section 3.05 only if the Debentures so delivered
to the Paying Agent shall conform in all respects to the description thereof in the Repurchase
Notice. All questions as to the validity, eligibility (including time of receipt) and acceptance

     (9) state whether the Debentures are then convertible, the then applicable Conversion Rate,
including, in the case of the occurrence of a Fundamental Change, expected changes in the

is being submitted is represented by a Global Debenture,



     (b) the principal amount of the Debentures with respect to which such notice of withdrawal is

     (c) the principal amount, if any, of such Debentures which remains subject to the original

.. Prior to 11:00 a.m., New York City Time, on the Business Day following the Fundamental Change
Repurchase Date or the

repurchase price of all the Debentures or portions thereof that are to be repurchased as of the
Fundamental Change Repurchase Date or the Repurchase Date, as the case may be.



     If on the Business Day following the Fundamental Change Repurchase Date or the Repurchase Date
the Paying Agent holds cash sufficient to pay the repurchase price of the Debentures that Holders
have elected to require the Company to repurchase in accordance with Section 3.04 or 3.05, as the
case may be, then, as of the Fundamental Change Repurchase Date or the Repurchase Date, as the case
may be, such Debentures will cease to be outstanding, interest will cease to accrue and all other
rights of the Holders of such Debentures will terminate, other than the right to receive the
repurchase price upon delivery or book-entry transfer of the Debentures. This will be the case
whether or not book-entry transfer of the Debentures has been made or the Debentures have been
delivered to the Paying Agent.



     SECTION 3.09 Debentures Repurchased in Part
.. Upon presentation of any Debentures repurchased only in part, the Company shall execute and the
Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of
the Company, a new Debenture or Debentures, of any authorized denomination, in aggregate principal

securities are not owned by Affiliate of the Company.



     SECTION 4.04 Existence
.. Except in compliance with Article V, the Company will do or cause to be done all things necessary

provided that the Company shall not be required to preserve any such right if the Company shall
determine that the preservation thereof is no longer desirable in the conduct of the business of
the Company and that the loss thereof is not disadvantageous in any material respect to the Holders
of Debentures.

or any Significant Subsidiary or upon the income, profits or property of the Company or any
Significant Subsidiary and (ii) all claims for labor, materials and supplies which, if unpaid,
might by law become a lien or charge upon the property of the Company or any Significant
Subsidiary; provided that the Company shall not be required to pay or discharge or cause to be paid
or discharged any such tax, assessment, charge or claim (A) if the failure to do so will not, in
the aggregate, have a material adverse impact on the Company, or (B) if the amount, applicability
or validity is being contested in good faith by appropriate proceedings.

     SECTION 4.06 Compliance Certificate. The Company
shall deliver to the Trustee within 120 days after the end of each fiscal
year of the Company an Officers’ Certificate stating that a review of the Company’s activities
during the preceding fiscal year has been made under the supervision of the signing Officers with a
view to determining whether the Company has kept, observed, performed and fulfilled its obligations
under this Indenture and further stating, as to each such Officer signing such certificate, whether
to the best of such Officer’s knowledge the Company during such preceding fiscal year has kept,
observed, performed and fulfilled each and every such covenant contained in this Indenture and
whether or not the signers know of any Default that occurred during such period. If they do know of
any Default, the certificate shall describe the Default, its status and what action the Company is
taking or proposes to take with respect thereto.



     SECTION 4.07 Further Instruments and Acts
.. The Company shall execute and deliver such further instruments and do such further acts as may be
reasonably necessary or proper to carry out more effectively the purpose of this Indenture.

required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act.



     (b) For the avoidance of doubt, this Section 4.10 is not intended to create any obligation to
timely file reports with the SEC.



     (c) Delivery of reports, information and other documents under this Section 4.10 to the
Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute
constructive notice of any information contained therein or determinable from information contained
therein, including the Company’s compliance with any of its covenants hereunder (as to which the
Trustee is entitled to rely exclusively on Officers’ Certificates).

transferee Person (if other than the Company) is a corporation or limited liability company
organized and existing under the laws of the United States, any state thereof or the District of

satisfactory in form and substance to the Trustee, of all of the obligations of the Company under
the Registration Rights Agreement, if required, such successor Person shall succeed to and be
substituted for the Company, with the same effect as if it had been named herein as the party of

Debentures, this Indenture and the Registration Rights Agreement. Such successor Person thereupon
may cause to be signed, and may issue either in its own name or in the name of Trico Marine
Services, Inc. any or all of the Debentures, issuable hereunder that theretofore shall not have
been signed by the Company and delivered to the Trustee; and, upon the order of such successor

the officers of the Company to the Trustee for authentication, and any Debentures that such
successor Person thereafter shall cause to be signed and delivered to the Trustee for that purpose.

time and such failure continues for 30 calendar days after the notice specified below;



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



34









 






     (1) commences a voluntary case;




     (2) consents to the entry of an order for relief against it in an involuntary case;




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




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




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



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




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




     (2) appoints a Custodian of the Company or any Significant Subsidiary or for any
substantial part of its property;




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




     (4) any similar relief is granted under any foreign laws and the order or decree
remains unstayed and in effect for 60 days.

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.



     The term “Bankruptcy Law” means Title 11, United States Code, or any similar Federal or state
law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee,
liquidator, custodian or similar official under any Bankruptcy Law.



     A Default under clause (e) or (f) above is not an Event of Default until the Trustee or the
Debentureholders of at least 25% in principal amount of the outstanding Debentures notify the
Company of the Default and the Company does not cure such Default within the time specified in such
clause (e) or (f) after receipt of such notice. Such notice must specify the Default, demand that
it be remedied and state that such notice is a “Notice of Default”.



     The Company shall deliver to the Trustee, promptly after the occurrence thereof, written
notice in the form of an Officers’ Certificate of any event which with the giving of notice or the
lapse of time would become an Event of Default, its status and what action the Company is taking or
proposes to take with respect thereto.



35









 





     SECTION 6.02 Acceleration
.. Subject to Section 6.13, if an Event of Default (other than an Event of Default specified in
Section 6.01(g) or (h)) occurs and is continuing, the Trustee by notice to the Company, or the
Debentureholders of at least 25% in principal amount of the outstanding Debentures by notice to the
Company, may declare the principal of and accrued but unpaid interest on all the Debentures to be
due and payable. Upon such a declaration, such principal and interest shall be due and payable
immediately. If an Event of Default specified in Section 6.01(g) or (h) occurs, the principal of
and interest on all the Debentures shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Debentureholders. The
Debentureholders of a majority in principal amount of the Debentures by notice to the Trustee may
rescind an acceleration and its consequences (including votes for or consents to such a rescission
obtained in connection with a purchase of, or tender offer or exchange offer for, Debentures) if
the rescission (i) would not conflict with any judgment or decree; (ii) if all existing Events of
Default have been cured or waived except nonpayment of principal or interest that has become due
solely because of acceleration; and (iii) if the Company has paid the compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel. No such rescission shall affect
any subsequent Default or impair any right consequent thereto.



     SECTION 6.03 Other Remedies
.. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to
collect the payment of principal of or interest on the Debentures or to enforce the performance of
any provision of the Debentures or this Indenture.



     The Trustee may maintain a proceeding even if it does not possess any of the Debentures or
does not produce any of them in the proceeding. A delay or omission by the Trustee or any
Debentureholder in exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No
remedy is exclusive of any other remedy. All available remedies are cumulative.



     SECTION 6.04 Waiver of Past Defaults
.. Subject to Section 6.02, the Holders of a majority in principal amount of the Debentures then
outstanding by notice to the Trustee may waive an existing Default and its consequences (including
votes for or consents to such a waiver obtained in connection with a purchase of, or tender offer
or exchange offer for, Debentures) except (i) a Default in the payment of the principal of or
interest (including additional interest, if any) on a Debenture, (ii) a Default arising from the
failure to redeem or repurchase any Debenture when required pursuant to the terms of this
Indenture, (iii) a Default arising from the failure of the Company to deliver cash and, if
applicable, Common Stock (including any Additional Shares) upon the conversion of any Debentures
pursuant to the terms of this Indenture or (iv) a Default in respect of a provision that under
Section 9.02 cannot be amended without the consent of each Debentureholder affected. When a Default
is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default
or impair any consequent right.



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



36









 







the rights of other Debentureholders or would involve
the Trustee in personal liability; provided, however, that the Trustee may take any other action
deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any
action hereunder, the Trustee shall be entitled to indemnification satisfactory to it in its sole
discretion against all losses and expenses caused by taking or not taking such action.



     SECTION 6.06 Limitation on Suits
.. Except to enforce the right to receive payment of principal, premium (if any) or interest when
due, no Debentureholder may pursue any remedy with respect to this Indenture or the Debentures
unless:



     (a) the Debentureholder gives to the Trustee written notice stating that an Event of Default
is continuing;



     (b) the Debentureholders of at least 25% in principal amount of the Debentures make a written
request to the Trustee to pursue the remedy;



     (c) such Debentureholder or Debentureholders offer to the Trustee reasonable security or
indemnity against any loss, liability or expense;



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



     (e) the Debentureholders of a majority in principal amount of the Debentures do not give the
Trustee a direction inconsistent with the request during such 60-day period. A Debentureholder may
not use this Indenture to prejudice the rights of another Debentureholder or to obtain a preference
or priority over another Debentureholder.



     SECTION 6.07 Rights of Debentureholders to Receive Payment
.. Notwithstanding any other provision of this Indenture, the right of any Debentureholder to
receive payment of principal of and liquidated damages and interest on the Debentures held by such
Debentureholder, on or after the respective due dates expressed in the Debentures, or to convert
such Debenture in accordance with Article 10, or to bring suit for the enforcement of any such
payment or right to convert on or after such respective dates, shall not be impaired or affected
without the consent of such Debentureholder.



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



     SECTION 6.09 Trustee May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents as may be necessary or
advisable in order to have the claims of the Trustee and the Debentureholders allowed in any
judicial proceedings relative to the Company, its creditors or its property and, unless prohibited
by law or applicable regulations, may vote on behalf of the Debentureholders in any election of a
trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such
judicial proceeding is hereby authorized by each Debentureholder to make payments to the Trustee
and,



37









 







in the event that the Trustee shall consent to the making of such payments directly to the
Debentureholders, to pay to the Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other
amounts due the Trustee under Section 7.07.



     SECTION 6.10 Priorities
.. If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the
money or property in the following order:



     FIRST: to the Trustee for amounts due under Section 7.07;



     SECOND: to Debentureholders for amounts due and unpaid on the Debentures for principal and
interest, ratably without preference or priority of any kind, according to the amounts due and
payable on the Debentures for principal and interest, respectively; and



     THIRD: to the Company.



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



     SECTION 6.11 Undertaking for Costs
.. In any suit for the enforcement of any right or remedy under this Indenture or in any suit
against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay the costs of the
suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a suit by the
Trustee, or a suit by Debentureholders of more than 10% in principal amount of the Debentures or to
any suit instituted by any Holder of Debentures for the enforcement of the payment of the principal
of, or premium, if any, or interest on any Debentures on or after the due date expressed in such
Debentures or to any suit for the enforcement of the right to convert any Debentures in accordance
with the provisions of Article 10.



     SECTION 6.12 Waiver of Stay, Extension or Usury Laws
.. The Company shall not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any
time hereafter in force, which may affect the covenants or the performance of this Indenture; and
the Company hereby expressly waives all benefit or advantage of any such law, and shall not hinder,
delay or impede the execution of any power herein granted to the Trustee, but shall suffer and
permit the execution of every such power as though no such law had been enacted.



     SECTION 6.13 Sole Remedy for Failure to Report.
Notwithstanding any other provision of this Indenture, the sole remedy for an Event of Default
relating to the failure of the Company to comply with its agreements under Section 4.10 of this
Indenture, and for any failure of the Company to comply with the requirements of Section 314(a)(1)
of the TIA, will for the 365 days after the occurrence of such an Event of Default consist
exclusively of the right to receive Additional Interest on the principal amount of the Debentures
at a rate equal to 0.50%



38









 







per annum. This Additional Interest will be in addition to any Additional
Interest that may accrue as a result of a registration default as described in the Registration
Rights Agreement and will be payable in the same manner and subject to the same terms as other
interest payable under this Indenture. The Additional Interest will accrue on all outstanding
Debentures from and including the date on which such Event of Default relating to a failure to
comply with Section 4.10 or Section 314(a)(1) of the TIA first occurs to but not excluding the
365th day thereafter (or such earlier date on which the Event of Default relating to a failure to
comply with Section 4.10 or Section 314(a)(1) of the TIA shall have been cured or waived). On such
365th day (or earlier, if the Event of Default relating to a failure to comply with Section 4.10
hereof or Section 314(a)(1) of the TIA is cured or waived prior to such 365th
day), such Additional Interest will cease to accrue and the Debentures will be subject to
acceleration and other remedies as provided in this Article 6 if the Event of Default is
continuing. For the avoidance of doubt, the provisions of this Section 6.13 will not affect the
rights of Holders of Debentures in the event of the occurrence of any other Event of Default and
will have no effect on the rights of Holders of Debentures under the Registration Rights Agreement.



ARTICLE 7

TRUSTEE




     SECTION 7.01 Duties of Trustee
.. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights
and powers vested in it by this Indenture and use the same degree of care and skill in its exercise
as a prudent Person would exercise or use under the circumstances in the conduct of such Person’s
own affairs.



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




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

     (2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed therein, upon
certificates or opinions furnished to the Trustee and conforming to the requirements of this
Indenture. However, the Trustee shall examine the certificates and opinions to determine
whether or not they conform to the requirements of this Indenture.

negligent failure to act or its own willful misconduct, except that:




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




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




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

paragraphs (a), (b) and (c) of this Section.



     (e) The Trustee shall not be liable for interest on any money received by it except as the
Trustee may agree in writing with the Company.



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



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



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



     SECTION 7.02 Rights of Trustee
.. (a) The Trustee may rely on any document believed by it to be genuine and to have been signed or
presented by the proper person. The Trustee need not investigate any fact or matter stated in the
document.



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



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



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



     (e) The Trustee may consult with counsel, and the advice or opinion of counsel with respect to

authorization and protection from liability in respect to any action taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such counsel.



     (f) The Trustee shall not be bound to make any investigation into the facts or matters stated
in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent,
order, approval, bond, debenture, note or other paper or document, but the Trustee, in its
discretion, may make such further inquiry or investigation into such facts or matters as it may see
fit.



     (g) The Trustee shall be under no obligation to exercise any of the rights or powers vested in
it by this Indenture at the request, order or direction of any of the Debentureholders pursuant to
the provisions of this Indenture, unless such Debentureholders shall have offered to



40









 







the Trustee
reasonable security or indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby.



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



     (i) The Trustee may request that the Company deliver an Officers’ Certificate setting forth
the names of individuals and/or titles of officers authorized at such time to take specified
actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person
authorized to sign an Officers’ Certificate, including any person specified as so authorized in any
such certificate previously delivered and not superseded.



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



     SECTION 7.03 Individual Rights of Trustee
.. The Trustee in its individual or any other capacity may become the owner or pledgee of Debentures
and may otherwise deal with the Company or its Affiliates with the same rights it would have if it
were not Trustee. Any Conversion Agent, Paying Agent, Registrar or co-paying agent may do the same
with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.



     SECTION 7.04 Trustee’s Disclaimer
.. The Trustee shall not be responsible for and makes no representation as to the validity or
adequacy of this Indenture or the Debentures, it shall not be accountable for the Company’s use of
the proceeds from the Debentures, and it shall not be responsible for any statement of the Company
in this Indenture or in any document issued in connection with the sale of the Debentures or in the
Debentures other than the Trustee’s certificate of authentication.



     SECTION 7.05 Notice of Defaults
.. (a) The Trustee shall not be deemed to have notice of any Default, other than a payment default,
unless a Trust Officer shall have been advised in writing that a Default has occurred. No duty
imposed upon the Trustee in this Indenture shall be applicable with respect to any Default of which
the Trustee is not deemed to have notice.



     (b) If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall
mail to each Debentureholder notice of the Default within the earlier of 90 days after it occurs or
30 days after it is known to a Trust Officer or written notice of it is received by the Trustee.
Except in the case of a Default in payment of principal, premium (if any) or interest on any
Debenture (including payments pursuant to the redemption provisions of such Debenture), the Trustee
may withhold notice if and so long as a committee of its Trust Officers in good faith determines
that withholding notice is in the interests of the Debentureholders.



     SECTION 7.06 Reports by Trustee to Debentureholders
.. As promptly as practicable after each July 15, beginning with July 15, 2008, and in any event
prior to December 31 in each subsequent year, the Trustee shall, to the extent that any of the
events described in TIA § 313(a) occurred within the previous twelve months, but not otherwise,
mail to



41









 







each Debentureholder a brief report dated as of July 15 that complies with Section 313(a)
of the TIA. The Trustee shall also comply with Section 313(b) of the TIA.



     A copy of each report at the time of its mailing to Debentureholders shall be filed with the
SEC and each stock exchange (if any) on which the Debentures are listed. The Company agrees to
notify promptly the Trustee, in writing, whenever the Debentures become listed on any stock
exchange and of any delisting thereof.



     SECTION 7.07 Compensation and Indemnity
.. The Company shall pay to the Trustee from time to time such compensation as the Company and the
Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited
by any law on compensation of a trustee of an express trust. The Company shall reimburse the
Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including
costs of collection, in addition to the compensation for its services. Such expenses shall include
the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents,
counsel, accountants and experts. The Company shall indemnify the Trustee, and hold it harmless,
against any and all loss, liability or expense (including reasonable attorneys’ fees) incurred by
or in connection with the offer and sale of the Debentures or the administration of this trust and
the performance of its duties hereunder. The Trustee shall notify the Company of any claim for
which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however,
that any failure so to notify the Company shall not relieve the Company of its indemnity
obligations hereunder. The Company shall defend the claim and the indemnified party shall provide
reasonable cooperation at the Company’s expense in the defense. Such indemnified parties may have
separate counsel and the Company shall pay the fees and expenses of such counsel; provided,
however, that the Company shall not be required to pay such fees and expenses if it assumes such
indemnified parties’ defense and, in such indemnified parties’ reasonable judgment, there is no
conflict of interest between the Company and such parties in connection with such defense. The
Company need not reimburse any expense or indemnify against any loss, liability or expense incurred
by an indemnified party through such party’s own willful misconduct and negligence.



     To secure the Company’s payment obligations in this Section, the Trustee shall have a lien
prior to the Debentures on all money or property held or collected by the Trustee other than money
or property held in trust to pay principal of and interest and any liquidated damages on particular
Debentures.



     The Company’s payment obligations pursuant to this Section shall survive the satisfaction or
discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy
law or the resignation or removal of the Trustee. When the Trustee incurs expenses after the
occurrence of a Default specified in Section 6.01(g) or (h) with respect to the Company, the
expenses are intended to constitute expenses of administration under the Bankruptcy Law.



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



42









 





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



     (b) the Trustee is adjudged bankrupt or insolvent;



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



     (d) the Trustee otherwise becomes incapable of acting.



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



     A successor Trustee shall deliver a written acceptance of its appointment to the retiring
Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall
become effective, and the successor Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to
Debentureholders. The retiring Trustee shall promptly transfer all property held by it as Trustee
to the successor Trustee, subject to the lien provided for in Section 7.07.



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



     If the Trustee fails to comply with Section 7.10, any Debentureholder may petition any court
of competent jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.



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



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



     In case at the time such successor or successors by merger, conversion or consolidation to the
Trustee shall succeed to the trusts created by this Indenture any of the Debentures shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Debentures so authenticated; and in
case at that time any of the Debentures shall not have been authenticated, any successor to the
Trustee may authenticate such Debentures either in the name of any predecessor hereunder or in
the name of the successor to the Trustee; and in all such cases such certificates shall have the
full force which it is anywhere in the Debentures or in this Indenture provided that the
certificate of the Trustee shall have.



43









 





     SECTION 7.10 Eligibility; Disqualification
.. The Trustee shall at all times satisfy the requirements of TIA § 310(a). The Trustee shall have a
combined capital and surplus of at least $100,000,000 as set forth in its most recent published
annual report of condition. The Trustee shall comply with TIA § 310(b); provided, however, that
there shall be excluded from the operation of TIA § 310(b)(1) any indenture or indentures under
which other securities or certificates of interest or participation in other securities of the
Company are outstanding if the requirements for such exclusion set forth in TIA § 310(b)(1) are
met.



     SECTION 7.11 Preferential Collection of Claims Against Company
.. The Trustee shall comply with TIA § 311(a), excluding any creditor relationship listed in TIA §
311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent
indicated.



ARTICLE 8

DISCHARGE OF INDENTURE




     SECTION 8.01 Discharge of Liability on Debentures
.. (a) When (i) the Company delivers to the Trustee all outstanding Debentures (other than
Debentures replaced pursuant to Section 2.09) for cancellation or (ii) all outstanding Debentures
have become due and payable, whether at maturity or upon a redemption or repurchase pursuant to
Article 3 hereof, and the Company irrevocably deposits with the Trustee money sufficient to pay at
maturity or upon redemption or repurchase all outstanding Debentures, including interest thereon to
maturity or such redemption or repurchase date (other than Debentures replaced pursuant to Section
2.09), and any shares of Common Stock or other property due in respect of converted Debentures, and
if in each such case the Company pays all other sums payable hereunder by the Company, then this
Indenture shall, subject to Section 8.01(b), cease to be of further effect. The Trustee shall
acknowledge satisfaction and discharge of this Indenture on demand of the Company accompanied by an
Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Company.



     (b) Notwithstanding clause (a) above, the Company’s obligations in Sections 2.05, 2.06, 2.07,
2.08, 2.09, 2.10, 7.07, 7.08 and in this Article 8 shall survive until the Debentures have been
paid in full. Thereafter, the Company’s obligations in Sections 7.07, 8.03 and 8.04 shall survive.



     SECTION 8.02 Application of Trust Money
.. The Trustee shall hold in trust money and any shares of Common Stock or other property due in
respect of converted Debentures deposited with it pursuant to this Article 8. It shall apply the
deposited money through the Paying Agent and in accordance with this Indenture to the payment of
principal of and interest on the Debentures or, in the case of any shares of Common Stock or other
property due in respect of converted Debentures, in accordance with this Indenture in relation to
the conversion of Debentures pursuant to the terms hereof.



     SECTION 8.03 Repayment to Company
.. The Trustee and the Paying Agent shall promptly turn over to the Company upon request any excess
money or securities held by them at any time.



44









 





     Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay
to the Company upon written request any money held by them for the payment of principal or interest
and any shares of Common Stock or other property due in respect of converted Debentures that
remains unclaimed for two years, and, thereafter, Debentureholders entitled to the money and/or
securities must look to the Company for payment as general creditors.



     SECTION 8.04 Reinstatement
.. If the Trustee or Paying Agent is unable to apply any money or to deliver any shares of Common
Stock or other property due in respect of converted Debentures in accordance with this Article 8 by
reason of any legal proceeding or by reason of any order or judgment of any court or governmental
authority enjoining, restraining or otherwise prohibiting such application, the Company’s
obligations under this Indenture and the Debentures shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 8 until such time as the Trustee or Paying Agent is
permitted to apply all such money and any shares of Common Stock or other property due in respect
of converted Debentures in accordance with this Article 8; provided, however, that, if the Company
has made any payment of interest on or principal of any Debentures because of the reinstatement of
its obligations, the Company shall be subrogated to the rights of the Debentureholders of such
Debentures to receive such payment from the money held by the Trustee or Paying Agent.



ARTICLE 9

AMENDMENTS




     SECTION 9.01 Without Consent of Debentureholders
.. The Company and the Trustee may amend this Indenture or the Debentures without notice to or
consent of any Debentureholder:



     (a) to cure any ambiguity, omission, defect or inconsistency; provided that such modification
or amendment does not adversely affect the interests of the Holders of the Debentures in any
material respect; provided, further, that any amendment made solely to conform the provisions of
this Indenture to the Description of the Debentures contained in the Company’s Offering Memorandum
dated February 1, 2007 will not be deemed to adversely affect the interests of the Holders of the
Debentures;



     (b) to comply with Article 5;



     (c) to provide for uncertificated Debentures in addition to or in place of certificated
Debentures; provided, however, that the uncertificated Debentures are issued in registered form for

described in Section 163(f)(2)(B) of the Code;



     (d) to add guarantees with respect to the Debentures or to secure the Debentures;



     (e) to add to the covenants of the Company for the benefit of the Debentureholders or to

     (f) to make any provision with respect to matters or questions arising under this Indenture
that the Company may deem necessary or desirable and that shall not be inconsistent with provisions
of this Indenture; provided that such change or modification does not, in the



45









 







good faith opinion of
the Company’s Board of Directors, adversely affect the interests of the Holders of the Debentures
in any material respect;



     (g) to provide for a successor Trustee;



     (h) to make any increase in the Conversion Rate;



     (i) to make any changes or modifications necessary in connection with the registrations of the

change or reclassification of the Common Stock, merger or consolidation, or sale, lease, transfer,
conveyance or other disposition of all or substantially all of the Company’s assets and those of
its Subsidiaries taken as a whole, including any adjustment contemplated by Section 10.06 or 10.13.



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



     SECTION 9.02 With Consent of Debentureholders
.. The Company and the Trustee may amend this Indenture or the Debentures with the written consent
of the Holders of at least a majority in principal amount of the Debentures then outstanding
(including consents obtained in connection with a tender offer or exchange offer for the
Debentures), without notice to any other Debentureholder. However, without the consent of each
Holder of an outstanding Debenture affected, an amendment may not:



     (a) reduce the percentage of the Debentures required for consent to any modification of this
Indenture that requires the consent of each affected Holder;



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

     (e) make any Debenture payable in money other than that stated in the Debenture;



     (f) change the redemption provisions in a manner adverse to the Holders;



46









 





     (g) change our obligation to repurchase any Debentures at the option of the Holder in a manner
adverse to the Holders;



     (h) change our obligation to repurchase any Debentures upon a Fundamental Change in a manner
adverse to the Holders;



     (i) impair the right of a Holder to institute suit for payment of any Debentures; or



     (j) except as otherwise permitted pursuant to this Indenture, adversely affect the right of a
Holder to convert any Debentures into cash, or reduce the number of shares of Common Stock or any
other property receivable upon conversion pursuant to the terms of this Indenture.



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



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



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



     SECTION 9.04 Revocation and Effect of Consents and Waivers
.. A consent to an amendment or a waiver by a Debentureholder of a Debenture shall bind the
Debentureholder and every subsequent Debentureholder of that Debenture or portion of the Debenture
that evidences the same debt as the consenting Debentureholder’s Debenture, even if notation of the
consent or waiver is not made on the Debenture. However, any such Debentureholder or subsequent
Debentureholder may revoke the consent or waiver as to such
Debentureholder’s Debenture or portion of the Debenture if the Trustee receives the notice of
revocation before the date the amendment or waiver becomes effective. After an amendment or waiver
becomes effective, it shall bind every Debentureholder. An amendment or waiver becomes effective
once both (i) the requisite number of consents have been received by the Company or the Trustee and
(ii) such amendment or waiver has been executed by the Company and the Trustee.



     The Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Debentureholders entitled to give their consent or take any other action described
above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed,
then notwithstanding the immediately preceding paragraph, those Persons who were Debentureholders
at such record date (or their duly designated proxies), and only those Persons, shall be entitled
to give such consent or to revoke any consent previously given or to take any such action, whether
or not such Persons continue to be Debentureholders after such record date. No such consent shall
be valid or effective for more than 120 days after such record date.



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



47









 





     For purposes of this Indenture, the consent of the Holder of a Global Debenture shall be
deemed to include any consent delivered by any member of, or participant in, any Depositary or DTC,
any nominees thereof and their respective successors and assigns, or such other depositary
institution hereinafter appointed by the Company (“Depositary Entity”) by electronic means in
accordance with the Automated Tender Offer Procedures system or other customary procedures of, and
pursuant to authorization by, such Depositary Entity.



     Without limiting the generality of this Section 9.04, unless otherwise provided in or pursuant
to this Indenture, a Holder, including a Depositary or its nominee that is a Holder of a Global
Debenture, may give, make or take, by an agent or agents duly appointed in writing, any request,
demand, authorization, direction, notice, consent, waiver or other action provided or permitted in
or pursuant to this Indenture to be given, made or taken by Holders, and a Depositary or its
nominee that is a Holder of a Global Debenture may duly appoint in writing as its agent or agents
members of, or participants in, such Depositary holding interests in such Global Debenture in the
records of such Depositary, with regard to all or any part of the principal amount of such
Debenture.



     Nothing in this paragraph shall be construed to prevent the Company or the Trustee from fixing
a new record date for any action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with no further action
by any Person be canceled and of no effect).



     SECTION 9.05 Notation on or Exchange of Debentures
.. If an amendment changes the terms of a Debenture, the Trustee may require the Debentureholder of
the Debenture to deliver it to the Trustee. The Trustee may place an appropriate notation on the
Debenture regarding the changed terms and return it to the
Debentureholder. Alternatively, if the Company or the Trustee so determines, the Company in
exchange for the Debenture shall issue and the Trustee shall authenticate a new Debenture that
reflects the changed terms. Failure to make the appropriate notation or to issue a new Debenture
shall not affect the validity of such amendment.



     SECTION 9.06 Trustee to Sign Amendments
.. The Trustee shall sign any amendment authorized pursuant to this Article 9 if the amendment does
not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may but need not sign it. In signing such amendment the Trustee shall be entitled to
receive, and (subject to Section 7.01) shall be fully protected in relying upon, in addition to the
documents required by Section 11.04, an Officers’ Certificate and an Opinion of Counsel stating
that such amendment is authorized or permitted by this Indenture and that such amendment is the
legal, valid and binding obligation of the Company enforceable against it in accordance with its
terms, subject to customary exceptions, and complies with the provisions hereof (including Section
9.03).



ARTICLE 10

CONVERSION OF DEBENTURES




     SECTION 10.01 Right to Convert
.. (a) Subject to and upon compliance with the provisions of this Indenture, on or prior to 5:00
p.m., New York City time, on the Business Day immediately preceding January 15, 2027, the Holder of
any Debentures not previously redeemed or repurchased shall have the right, at such Holder’s
option, to convert the principal amount of



48









 







the Debentures held by such Holder, or any portion of
such principal amount which is an integral multiple of $1,000, into cash and, if applicable, fully
paid and non-assessable shares of Common Stock (as such shares shall then be constituted) as
described in Section 10.12, at the Conversion Rate in effect at such time, by surrender of the
Debentures so to be converted in whole or in part, together with any required funds, under the
circumstances described in this Section 10.01 and in the manner provided in Section 10.02. The
Debentures shall be convertible, on or prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding January 15, 2027, only during the following periods:




     (1) prior to January 15, 2025, on any date during any Fiscal Quarter beginning after
March 31, 2007 (and only during such Fiscal Quarter), if the Closing Sale Price of a share
of Common Stock was more than 125% of the then current Conversion Price for at least 20
Trading Days in the 30 consecutive Trading-Day period ending on the last Trading Day of the
immediately preceding Fiscal Quarter;




     (2) on any date that is on or after January 15, 2025;




     (3) with respect to Debentures called for redemption pursuant to Section 3.01, until
5:00 p.m., New York City time, on the Business Day prior to the relevant redemption date;




     (4) if the Company distributes to all or substantially all holders of Common Stock
rights or warrants (other than pursuant to a shareholder rights plan) entitling them to
purchase, for a period of 45 calendar days or less, Common Stock at less than the average
Closing Sale Price per share of the Common Stock for the 10 Trading Days preceding the
declaration date for such distribution, on any date during the period specified in Section
10.01(c);




     (5) if the Company distributes to all or substantially all holders of Common Stock,
cash or other assets, debt securities or rights to purchase the Company’s securities (other
than pursuant to a shareholder rights plan, share split of Common Stock or a dividend or
distribution on its Common Stock in shares of Common Stock), which distribution has a per
share value as determined by the Board of Directors exceeding 10% of the Closing Sale Price
per share of the Common Stock on the Trading Day preceding the declaration for such
distribution, on any date during the period specified in Section 10.01(c);




     (6) if a Fundamental Change occurs, at any time beginning on the Business Day following
the effective date of the Fundamental Change until 5:00 p.m., New York City time, on the
Business Day preceding the Fundamental Change Repurchase Date relating to such Fundamental
Change;




     (7) during the five consecutive Business Days immediately following any ten consecutive
Trading-Day period in which the Trading Price per $1,000 principal amount of the Debentures
was less than 98% of the average of the Closing Sale Price of a share of Common Stock during
such ten Trading-Day period multiplied by the applicable Conversion Rate; or



49









 






     (8) as specified in Section 10.01(d).



     (b) (1) The Company shall, at the Trustee’s request, notify the Trustee in writing whether the
condition to conversion set forth in Section 10.01(a)(1) above shall have been satisfied with
respect to such calendar quarter.




     (2) The Trustee shall have no obligation to determine the Trading Price of the
Debentures and whether the Debentures are convertible pursuant to clause (7) of Section
10.01(a) unless the Company has requested such determination; and the Company shall have no
obligation to make such request unless a Holder of the Debentures makes a request for a
determination and provides the Company with reasonable evidence that the Trading Price per
$1,000 principal amount of Debentures is below the required threshold (i.e., 98% of the
product of the Closing Sale Price of the Common Stock and the Conversion Rate then in
effect). At such time, the Company shall instruct the Trustee to determine the Trading Price
of the Debentures beginning on the next Trading Day and on each successive Trading Day until
the Trading Price for the Debentures for a Trading Day is at least 98% of the product of the
Closing Sale Price of the Common Stock and the then current Conversion Rate, and to notify
the Company accordingly.



     The Trustee shall be entitled at its sole discretion to consult with the Company and to
request the assistance of the Company in connection with the Trustee’s duties and obligations
pursuant to Section 10.01(b)(2) hereof (including without limitation the calculation or
determination of the Conversion Rate, the Closing Sale Price and the Trading Price), and the
Company agrees, if requested by the Trustee, to cooperate with, and provide assistance to, the
Trustee in carrying out its duties under this Section 10.01.



     (c) In the case of a distribution contemplated by clauses (4) or (5) of Section 10.01(a), the
Company shall notify Holders of Debentures at least 10 Business Days prior to the “ex” date for
such distribution (the “Distribution Notice”). Once the Company has given the Distribution Notice,
Holders may surrender their Debentures for conversion at any time until the earlier of (i) 5:00
p.m., New York City time, on the Business Day immediately preceding the “ex” date or (ii) the
Company’s announcement that such distribution will not take place. In the event of a distribution
contemplated by clauses (4) or (5) of Section 10.01(a), Holders may not convert the Debentures if
the Holders may otherwise participate in such distribution without converting their Debentures.



     (d) In addition, if the Company consolidates with or merges with or into another Person or is
a party to a binding share exchange or conveys, transfers, sells, leases or otherwise disposes of
all or substantially all of its properties and assets (other than a consolidation, merger, binding
share exchange or sale or conveyance, the primary purpose of which is to effect a reincorporation
or redomiciling of the Company) in each case in a transaction not constituting a Fundamental
Change, in each case pursuant to which the Common Stock would be converted into cash, securities
and/or other property, then the Holders shall have the right to convert their Debentures at any
time beginning fifteen calendar days prior to the date announced by the Company as the anticipated
effective date of the transaction and until and including the date which is 15 calendar days after
the date that is the actual effective date of such transaction.



50









 





     The Company shall determine the anticipated effective date of the transaction (which
determination shall be conclusive for purposes of commencing the convertibility period described in
the preceding paragraph), and publicly announce such date not later than 20 calendar days prior to
such date.



     (e) Whenever the Debentures shall become convertible pursuant to Section 10.01(a)(6) or (7),
the Company or, at the Company’s request, the Trustee in the name and at the expense of the
Company, shall notify the Holders of the event triggering such convertibility in the manner
provided in Section 11.02, and the Company shall also publicly announce such information. Any
notice so given shall be conclusively presumed to have been duly given, whether or not the Holder
receives such notice. The Company shall determine the anticipated effective date of any Fundamental
Change (which determination shall be conclusive for purposes of this sentence) and notify Holders
at least 10 calendar days prior to the anticipated effective date of any Fundamental Change, to the
extent practicable and in any event, no later than the effective date thereof.



     (f) Debentures in respect of which a Holder has delivered a Repurchase Notice exercising such
Holder’s right to require the Company to repurchase such Debentures pursuant to Section 3.04 or
3.05 may be converted only if such Repurchase Notice is withdrawn in
accordance with Section 3.07 prior to 5:00 p.m., New York City time, on the Business Day
immediately preceding the Repurchase Date or the Fundamental Change Repurchase Date, as applicable.



     (g) A Holder of Debentures is not entitled to any rights of a holder of Common Stock until
such Holder has converted his Debentures to Common Stock, and only to the extent such Debentures
are deemed to have been converted to Common Stock under this Article 10.



     SECTION 10.02 Exercise of Conversion Right; Issuance of Common Stock on Conversion; No
Adjustment for Interest or Dividends
.. In order to exercise the conversion right with respect to any Debentures in certificated form,
the Company must receive at the office or agency of the Company maintained for that purpose or, at
the option of such Holder, the Corporate Trust Office, such Debentures with the original or
facsimile of the form entitled “Conversion Notice” on the reverse thereof, duly completed and
manually signed, together with such Debentures duly endorsed for transfer, together with any other
required transfer documents, accompanied by the funds, if any, required by this Section 10.02.
Such notice shall also state the name or names (with address or addresses) in which the certificate
or certificates for shares of Common Stock which shall be issuable on such conversion shall be
issued, and shall be accompanied by transfer or similar taxes or duties, if required pursuant to
Section 10.07.



     In order to exercise the conversion right with respect to any interest in a Global Debenture,
the Holder must complete, or cause to be completed, the appropriate instruction form for conversion
pursuant to the Depositary’s book-entry conversion procedures; deliver, or cause to be delivered,
by book-entry delivery an interest in such Global Debenture; furnish appropriate endorsements and
transfer documents if required by the Company or the Trustee or conversion agent; and pay the
funds, if any, required by this Section 10.02 and any transfer or similar taxes or duties if
required pursuant to Section 10.07.



51









 





     The cash and, if applicable, a certificate or certificates for the number of full shares of
Common Stock into which the Debentures are converted (and cash in lieu of fractional shares) will
be delivered to such Holder after satisfaction of the requirements for conversion set forth above,
in accordance with Section 10.12. In case any Debentures of a denomination greater than $1,000
shall be surrendered for partial conversion, and subject to Section 2.03, the Company shall execute
and the Trustee shall authenticate and deliver to the Holder of the Debentures so surrendered,
without charge to the Holder, a new Debenture or Debentures in authorized denominations in an
aggregate principal amount equal to the unconverted portion of the surrendered Debentures.



     Each conversion shall be deemed to have been effected as to any such Debentures (or portion
thereof) on the date on which the requirements set forth above in this Section 10.02 have been
satisfied as to such Debentures (or portion thereof) (the “Conversion Date”) and such Debentures
will be deemed to have been converted immediately prior to 5:00 p.m., New York City time, on the
Conversion Date. The Person in whose name any certificate or certificates for shares of Common
Stock shall be issuable upon such conversion shall be deemed to have become, on said date, the
holder of record of the shares represented thereby; provided that any
such surrender on any date when the stock transfer books of the Company shall be closed shall
constitute the Person in whose name the certificates are to be issued as the record holder thereof
for all purposes on the next succeeding day on which such stock transfer books are open.



     Any Debentures or portion thereof surrendered for conversion during the period from 5:00 p.m.,
New York City time, on the Record Date for any interest payment date to 5:00 p.m., New York City
time, on the Business Day preceding the applicable interest payment date shall be accompanied by
payment, in immediately available funds or other funds acceptable to the Company, of an amount
equal to the interest (excluding any Additional Interest) otherwise payable on such interest
payment date on the principal amount being converted; provided that no such payment need be made
(1) if a Holder converts its Debentures in connection with a redemption and the Company has
specified a redemption date that is after a Record Date and on or prior to the corresponding
interest payment date, (2) if a Holder converts its Debentures in connection with a Fundamental
Change and the Company has specified a Fundamental Change Repurchase Date that is after a Record
Date and on or prior to the corresponding interest payment date or (3) to the extent of any overdue
interest, if any overdue interest exists at the time of conversion with respect to such Debentures.
Except as provided above in this Section 10.02 and Section 10.05, no payment or other adjustment
shall be made for interest accrued on any Debentures converted or for dividends on any shares
issued upon the conversion of such Debentures as provided in this Article 10.



     Upon the conversion of an interest in a Global Debenture, the Trustee (or other conversion
agent appointed by the Company), or the custodian for the Global Debenture at the direction of the
Trustee (or other conversion agent appointed by the Company), shall make a notation on such Global
Debenture as to the reduction in the principal amount represented thereby. The Company shall
notify the Trustee in writing of any conversions of Debentures effected through any conversion
agent other than the Trustee.



     Upon the conversion of any Debentures, the accrued but unpaid interest attributable to the
period from the issue date of the Debentures to the Conversion Date, with respect to the



52









 







converted Debentures, shall not be cancelled, extinguished or forfeited, but rather shall be deemed to be
paid in full to the Holder thereof through delivery of the cash (including a cash payment in lieu
of fractional shares, if any) and shares of Common Stock, if any, in exchange for the Debentures
being converted pursuant to the provisions hereof.



     SECTION 10.03 Cash Payments in Lieu of Fractional Shares
.. No fractional shares of Common Stock or scrip certificates representing fractional shares shall
be issued upon conversion of Debentures. If more than one Debenture shall be surrendered for
conversion at one time by the same Holder, the number of full shares that shall be issuable upon
conversion shall be computed on the basis of the aggregate principal amount of the Debentures (or
specified portions thereof to the extent permitted hereby) so surrendered. If any fractional share
of stock would be issuable upon the conversion of any Debenture or Debentures, the Company shall
make an adjustment and payment therefor in cash to the Holder of Debentures at a price equal to the
Volume Weighted Average Price on the final Trading Day of the Conversion Settlement Averaging
Period.



     SECTION 10.04 Conversion Rate.



     (a) Each $1,000 principal amount of the Debentures shall be convertible into cash and the
number of shares of Common Stock, if any, based upon the Conversion Rate, which is subject to
adjustment as provided in this Section 10.04 and Section 10.05.



     (b) Subject to Section 10.13, if and only to the extent a Holder elects to convert Debentures
at any time following the date on which a Non-Stock Change of Control becomes effective (the
“Effective Date”) but before 5:00 p.m., New York City time, on the Business Day immediately
preceding the related Fundamental Change Purchase Date, the Company shall increase the Conversion
Rate applicable to such converted Debentures by a number of additional shares of Common Stock (the
“Additional Shares”) as set forth below provided that the Effective Date is prior to January 15,
2012. The number of Additional Shares shall be determined by reference to the table below, based on
the Effective Date and the price (the “Stock Price”) paid per share for the Common Stock in the
Non-Stock Change of Control. If holders of Common Stock receive only cash in the Non-Stock Change
of Control, the Stock Price shall be the cash amount paid per share. Otherwise, the Stock Price
shall be the average of the Closing Sale Prices of the Common Stock on the five Trading Days prior
to but not including the Effective Date of such Non-Stock Change of Control.



     The numbers of Additional Shares set forth in the table below shall be adjusted as of any date
on which the Conversion Rate is adjusted in the same manner in which the Conversion Rate is
adjusted. The Stock Prices set forth in the table below shall be adjusted, as of any date on which
the Conversion Rate is adjusted, to equal the Stock Price applicable immediately prior to such
adjustment multiplied by a fraction, of which




     (1) the numerator shall be the Conversion Rate immediately prior to the adjustment and




     (2) the denominator shall be the Conversion Rate as so adjusted.



53









 





     The following table sets forth the Stock Price and number of Additional Shares by which the
Conversion Rate shall be increased:

     If the Stock Price and Effective Date are not set forth on the table above and the Stock
Price is:




     (i) between two Stock Prices on the table or the Effective Date is between two days on
the table, the number of Additional Shares shall be determined by straight-line
interpolation between the number of Additional Shares of Common Stock set forth for the
higher and lower Stock Price and the two Effective Dates, as applicable, based on a 360-day
year;




     (ii) in excess of $150.00 per share (subject to adjustment in the same manner as and as
of any date on which the Stock Prices are adjusted in the table above), no Additional Shares
of Common Stock shall be issued upon conversion; or




     (iii) less than $31.25 per share (subject to adjustment in the same manner as and as of
any date on which the Stock Prices are adjusted in the table above), no Additional Shares
shall be issued upon conversion.



     Notwithstanding the foregoing, in no event will the Conversion Rate as adjusted pursuant to
this Section 10.04 exceed 32.0000 per $1,000 principal amount of the Debentures, subject to
adjustments in the same manner as and as of any date on which the numbers of Additional Shares set
forth in the above table are adjusted as set forth in the second paragraph of this Section
10.04(b).



     SECTION 10.05 Adjustment of Conversion Rate
.. The Conversion Rate shall be adjusted from time to time by the Company as follows:



     (a) In case the Company shall, at any time or from time to time while any of the Debentures
are outstanding, pay a dividend in shares of Common Stock or make a distribution in shares of
Common Stock to all or substantially all Holders of its outstanding shares of Common Stock (other
than a dividend or distribution upon a transaction to which Section 10.06 applies), then the
Conversion Rate in effect at the opening of business on the date following the Record Date fixed
for the determination of stockholders entitled to receive such dividend or other distribution shall
be increased by multiplying such Conversion Rate by a fraction:



54









 






     (1) the numerator of which shall be the sum of the number of shares of Common Stock
outstanding at the close of business on the Record Date fixed for the determination of
stockholders entitled to receive such dividend or other distribution plus the total number
of shares of Common Stock constituting such dividend or other distribution; and




     (2) the denominator of which shall be the number of shares of Common Stock outstanding
at the close of business on the Record Date fixed for such determination, such increase to
become effective immediately after the opening of business on the day following the Record
Date fixed for such determination. If any dividend or distribution of the type described in
this Section 10.05(a) is declared but not so paid or made, the Conversion Rate shall again
be adjusted to the Conversion Rate that would then be in effect if such dividend or
distribution had not been declared.



     (b) In case outstanding shares of Common Stock shall be subdivided into a greater number of
shares of Common Stock (other than upon a transaction to which Section 10.06
applies), the Conversion Rate in effect at the opening of business on the day following the
day upon which such subdivision becomes effective shall be proportionately increased, and
conversely, in case outstanding shares of Common Stock shall be combined into a smaller number of
shares of Common Stock (other than upon a transaction to which Section 10.06 applies), the
Conversion Rate in effect at the opening of business on the day following the day upon which such
combination becomes effective shall be proportionately reduced, such increase or reduction, as the
case may be, to become effective immediately after the opening of business on the day following the
day upon which such subdivision or combination becomes effective.



     (c) In case the Company shall issue rights or warrants to all or substantially all holders of
its outstanding shares of Common Stock (other than upon a transaction to which Section 10.06
applies) entitling them to purchase, for a period of up to 45 calendar days, shares of Common Stock
at a price per share less than the then Current Market Price, the Conversion Rate shall be
increased so that the same shall equal the rate determined by multiplying the Conversion Rate in
effect immediately prior to the Record Date fixed for determination of stockholders entitled to
receive such rights or warrants by a fraction,




     (1) the numerator of which shall be the number of shares of Common Stock outstanding at
the close of business on the Record Date fixed for determination of stockholders entitled to
receive such rights or warrants plus the total number of additional shares of Common Stock
offered for subscription or purchase, and




     (2) the denominator of which shall be the sum of the number of shares of Common Stock
outstanding at the close of business on the Record Date fixed for determination of
stockholders entitled to receive such rights or warrants plus the number of shares that the
aggregate offering price of the total number of shares so offered would purchase at the
Current Market Price.



     Such adjustment shall be successively made whenever any such rights or warrants are issued,
and shall become effective immediately after the opening of business on the day following the date
fixed for determination of stockholders entitled to receive such rights or



55









 







warrants; provided, that
no adjustment to the Conversion Rate shall be made if the Holder will otherwise participate in such
distribution without conversion as a result of holding the Debentures. To the extent that shares
of Common Stock are not delivered after the expiration of such rights or warrants, the Conversion
Rate shall be readjusted to the Conversion Rate that would then be in effect had the adjustments
made upon the issuance of such rights or warrants been made on the basis of delivery of only the
number of shares of Common Stock actually delivered. If such rights or warrants are not so issued,
the Conversion Rate shall again be adjusted to be the Conversion Rate that would then be in effect
if such date fixed for the determination of stockholders entitled to receive such rights or
warrants had not been fixed. In determining whether any rights or warrants entitle the Holders to
purchase shares of Common Stock at less than such Current Market Price, and in determining the
aggregate offering price of such shares of Common Stock, there shall be taken into account any
consideration received by the Company for such rights or warrants and any amount payable on
exercise or conversion thereof, the value of such consideration, if other than cash, to be
determined by the Board of Directors.



     (d) In case the Company shall, by dividend or otherwise, distribute to all or substantially
all holders of its outstanding shares of Common Stock shares of any class of capital stock of the
Company or evidences of its indebtedness or assets (including securities, but excluding (i) any
rights or warrants referred to in Section 10.05(c), (ii) any dividends or distributions in
connection with a transaction to which Section 10.06 applies, (iii) any dividends or distributions
paid exclusively in cash or (iv) any dividends or distributions referred to in Section 10.05(a))
(any of the foregoing hereinafter in this Section 10.05(d)) called the “Distributed Assets”), then,
in each such case, the Conversion Rate shall be increased so that the same shall be equal to the
rate determined by multiplying the Conversion Rate in effect on the Record Date with respect to
such distribution by a fraction,




     (1) the numerator of which shall be the Current Market Price; and




     (2) the denominator of which shall be the Current Market Price less the Fair Market
Value (as determined by the Board of Directors, whose determination shall be conclusive, and
described in a resolution of the Board of Directors) on the Record Date of the portion of
the Distributed Assets so distributed applicable to one share of Common Stock, such
adjustment to become effective immediately prior to the opening of business on the day
following such Record Date; provided that if the then Fair Market Value (as so determined)
of the portion of the Distributed Assets so distributed applicable to one share of Common
Stock is equal to or greater than the Current Market Price or such Current Market Price
exceeds such Fair Market Value by less than $1.00, in lieu of the foregoing adjustment,
adequate provision shall be made so that the Holder of each Debenture shall have the right
to receive upon conversion the amount of Distributed Assets such Holder would have received
had such Holder converted such Debenture immediately prior to the Record Date; and provided,
further, that no adjustment to the Conversion Rate shall be made if the Holder will
otherwise participate in such distribution without conversion as a result of holding the
Debentures. Solely for purposes of the preceding sentence, the amount of Distributed Assets
the Holder of a Debenture would have received had such Holder converted such Debenture shall
be determined as if such conversion were effected solely into shares of Common Stock
(without giving effect to Section 10.12). If such



56









 







dividend or distribution is not so paid
or made, the Conversion Rate shall again be adjusted to be the Conversion Rate that would
then be in effect if such dividend or distribution had not been declared.


Notwithstanding the foregoing, in the event any such distribution consists of shares of Capital
Stock of one or more of the Company’s Subsidiaries to be traded in a securities market (a
“Spin-Off”), the Conversion Rate shall be increased so that the same shall be equal to the rate
determined by multiplying the Conversion Rate in effect immediately prior to the close of business
on the Record Date with respect to such distribution by a fraction:





     (1) the numerator of which shall be the Current Market Price of the Common Stock
determined for the period specified below, plus the Fair Market Value of the portion of the
Distributed Assets so distributed applicable to one share of Common Stock, determined as set
forth above, and




     (2) the denominator of which shall be the Current Market Price determined for the
period specified below;


and such increase shall become effective immediately prior to the opening of business on the day
following the last Trading Day of the Spin-Off Valuation Period (as defined below). For purposes of
this paragraph, the Fair Market Value of the securities to be distributed shall equal the average
of the Closing Sale Prices of such securities on the principal securities market on which such
securities are traded for the five consecutive Trading Days commencing on and including the sixth
day of trading of those securities after the effectiveness of the Spin-Off (the “Spin-Off Valuation
Period”), and the Current Market Price of the Common Stock shall be measured for the same period.
In the event, however, that an underwritten initial public offering of the securities in the
Spin-Off occurs simultaneously with the Spin-Off, Fair Market Value of the securities distributed
in the Spin-Off shall mean the initial public offering price of such securities and the Current
Market Price of the Common Stock shall mean the Closing Sale Price for the Common Stock on the same
Trading Day.




     Rights or warrants distributed by the Company to all holders of Common Stock entitling the
Holders thereof to subscribe for or purchase shares of the Company’s capital stock (either
initially or under certain circumstances), which rights 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 10.05 (and
no adjustment to the Conversion Rate under this Section 10.05 will be required) until the
occurrence of the earliest Trigger Event, whereupon such rights and warrants shall be deemed to
have been distributed and an appropriate adjustment (if any is required) to the Conversion Rate
shall be made under this Section 10.05(d). If any such right or warrant, including any such
existing rights or warrants distributed prior to the date of this Indenture, are subject to events,
upon the occurrence of which such rights or warrants become exercisable to purchase different
securities, evidences of indebtedness or other assets, then the date of the occurrence of any and
each such event shall be deemed to be the date of distribution and record date with respect to new
rights or warrants with such rights (and a termination or expiration of the existing rights or
warrants without exercise by any of the holders thereof). In addition, in the event of any



57









 







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 10.05 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 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.



     No adjustment of the Conversion Rate shall be made pursuant to this Section 10.05(d) in
respect of rights or warrants distributed or deemed distributed on any Trigger Event to the extent
that such rights or warrants are actually distributed or reserved by the Company for distribution
to Holders of Debentures upon conversion by such Holders of Debentures to Common Stock.



     (e) In case the Company shall pay a dividend or otherwise distribute to all holders of its
Common Stock a dividend or other distribution of exclusively cash excluding (x) any dividend or
distribution in connection with the liquidation, dissolution or winding up of the Company, whether
voluntary or involuntary and (y) any dividend or distribution in connection with a transaction to
which Section 10.06 applies), then the Conversion Rate shall be increased so that the same shall
equal the rate determined by multiplying the Conversion Rate in effect on the applicable Record
Date by a fraction,




     (1) the numerator of which shall be the Current Market Price; and




     (2) the denominator of which shall be the Current Market Price less the amount of the
cash distribution applicable to one share of Common Stock, such adjustment to be effective
immediately prior to the opening of business on the day following such Record Date; provided
that if the portion of the cash so distributed applicable to one share of Common Stock is
equal to or greater than the Current Market Price, in lieu of the foregoing adjustment,
adequate provision shall be made so that each Holder of Debentures shall have the right to
receive upon conversion the amount of cash such Holder would have received had such Holder
converted such Debenture immediately prior to the Record Date. Solely for purposes of the
preceding sentence, the amount of cash the Holder of a Debenture would have received had
such Holder converted such Debenture shall be determined as if such conversion were effected
solely into shares of Common Stock (without giving effect to Section 10.12). If such
dividend or distribution is not so paid or made, the Conversion Rate shall again be adjusted
to be the Conversion Rate that would then be in effect if such dividend or distribution had
not been declared.



     (f) In case a tender or exchange offer made by the Company or any Subsidiary for all or any
portion of the Common Stock shall expire and such tender or exchange offer (as amended



58









 







upon the expiration thereof) shall require the payment to stockholders of consideration per share of Common
Stock having a Fair Market Value (as determined by the Board of Directors, whose determination
shall be conclusive and described in a resolution of the Board of Directors) that as of the last
time (the “Expiration Time”) tenders or exchanges may be made pursuant to such tender or exchange
offer (as it may be amended) exceeds the Closing Sale Price of a share of Common Stock on the
Trading Day next succeeding the Expiration Time, the Conversion Rate shall be increased so that the
same shall equal the rate determined by multiplying the Conversion Rate in effect immediately prior
to the Expiration Time by a fraction,




     (1) the numerator of which shall be the sum of (x) the Fair Market Value (determined as
aforesaid) of the aggregate consideration payable to stockholders whose shares are validly
tendered or exchanged and not withdrawn as of the Expiration Time and accepted for purchase
(the shares so accepted being referred to as the “Purchased Shares”) and (y) the product of
the number of shares of Common Stock outstanding (less
any Purchased Shares) at the Expiration Time and the Closing Sale Price of a share of
Common Stock on the Trading Day next succeeding the Expiration Time, and




     (2) the denominator of which shall be the number of shares of Common Stock outstanding
(including any Purchased Shares) at the Expiration Time multiplied by the Closing Sale Price
of a share of Common Stock on the Trading Day next succeeding the Expiration Time,


such adjustment to become effective immediately prior to the opening of business on the Business
Day following the Expiration Time. If the Company is obligated to purchase shares pursuant to any
such tender or exchange offer, but the Company is permanently prevented by applicable law from
effecting any such purchases or all such purchases are rescinded, the Conversion Rate shall again
be adjusted to be the Conversion Rate that would then be in effect if such tender or exchange offer
had not been made.




     (g) For purposes of this Section 10.05, the following terms shall have the meaning indicated:




     (i) “Current Market Price,” with respect to any issuance or distribution, means, except
as otherwise provided in Section 10.05(d), the average of the daily Closing Sale Prices per
share of Common Stock for the ten consecutive Trading Days immediately prior to the “ex”
date for such issuance or distribution requiring such computation; provided that if the “ex”
date (as hereinafter defined) for any event (other than the issuance or distribution
requiring such computation) that requires an adjustment to the Conversion Rate pursuant to
Section 10.05(a), (b), (c), (d), (e) or (f) occurs during such ten consecutive Trading Days,
the Closing Sale Price for each Trading Day prior to the “ex” date for such other event
shall be adjusted by dividing such Closing Sale Price by the same fraction by which the
Conversion Rate is so required to be multiplied as a result of such other event.




Notwithstanding the foregoing, whenever successive adjustments to the Conversion Rate are
called for pursuant to this Section 10.05, such adjustments shall be made to the Current
Market Price as may be necessary or appropriate to effectuate the intent of this



59









 







Section
10.05 and to avoid unjust or inequitable results as determined in good faith by the Board of
Directors.




     (ii) “‘ex’ date”:




     (1) when used in this Article 10 with respect to any issuance or distribution, means
the first date on which the shares of Common Stock trade regular way on the relevant
exchange or in the relevant market from which the Closing Sale Price was obtained without
the right to receive such issuance or distribution;




     (2) when used in the proviso to Section 10.05(g)(i) with respect to any subdivision or
combination of shares of Common Stock, means the first date on which the shares of Common
Stock trade regular way on such exchange or in such market after the time at which such
subdivision or combination becomes effective; and




     (3) when used in the proviso to Section 10.05(g)(i) with respect to any tender or
exchange offer, means the first date on which the shares of Common Stock trade regular way
on such exchange or in such market after the Expiration Time of such offer.




     (iii) “Fair Market Value” shall mean the amount which a willing buyer would pay a
willing seller in an arm’s-length transaction.




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




     (v) “Trading Day” means any day that is scheduled to be a trading day on the primary
United States national securities exchange or market on which the Common Stock is listed,
admitted to trading or quoted on which (i) there is no Market Disruption Event and (ii) The
Nasdaq Global Select Market (or, if the Company’s common stock is not quoted on The Nasdaq
Global Select Market, the principal U.S. national or regional securities exchange on which
the Common Stock is listed or admitted to trading), is open for trading or, if the Common
Stock is not so listed, admitted for trading or quoted, any Business Day. A “Trading Day”
includes only those scheduled trading days that have a scheduled closing time of 4:00 p.m.
(New York City time) or the then standard closing time for regular trading on the relevant
exchange or market.



     (h) The Company may make such increases in the Conversion Rate, in addition to those required
by Section 10.05(a)-(f), as the Board of Directors considers to be advisable to avoid or diminish
any income tax to holders of Common Stock or rights to purchase Common Stock resulting from any
dividend or distribution of stock (or rights to acquire stock) or from any event treated as such
for income tax purposes.



60









 





     In addition to the foregoing, to the extent permitted by applicable law, the Company from time
to time may increase the Conversion Rate by any amount for any period of time if the period is at
least 20 Business Days, the increase is irrevocable during the period and the Board of Directors
shall have made a determination that such increase would be in the best interests of the Company,
which determination shall be conclusive. Whenever the Conversion Rate is increased pursuant to the
preceding sentence, the Company shall mail to Holders of record of the Debentures a notice of the
increase, which notice will be given at least 15 days prior to the effectiveness of any such
increase, and such notice shall state the increased Conversion Rate and the period during which it
will be in effect.



     (i) No adjustment in the Conversion Rate shall be required unless such adjustment would
require an increase or decrease of at least one percent (1%) in such rate; provided that any
adjustments that by reason of this Section 10.05(i) are not required to be made shall be carried
forward and the Company shall make such carry forward adjustments, regardless of whether the
aggregate adjustment is less than 1%, (x) annually on the anniversary of the Closing Date and
otherwise (y)(1) five Business Days prior to the maturity of the Debentures (whether at stated
maturity or otherwise) or (2) prior to the redemption date or Repurchase Date or Fundamental Change
Repurchase Date, unless such adjustment has already been made. All calculations under this Article
10 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 need be made for rights to
purchase Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for
any issuance of Common Stock or convertible or exchangeable securities or rights to purchase Common
Stock or convertible or exchangeable securities. Interest will not accrue on any cash into which
the Debentures are convertible.



     (j) Whenever the Conversion Rate is adjusted as herein provided, the Company will issue a
press release containing the relevant information and make this information available on the
Company’s website or through another public medium as the Company may use at that time. In
addition, the Company shall promptly file with the Trustee and any conversion agent other than the
Trustee an Officers’ Certificate setting forth the Conversion Rate after such adjustment and
setting forth a brief statement of the facts requiring such adjustment. Unless and until a
responsible officer of the Trustee shall have received such Officers’ Certificate, the Trustee
shall not be deemed to have knowledge of any adjustment of the Conversion Rate and may assume that
the last Conversion Rate of which it has actual knowledge is still in effect. Promptly after
delivery of such certificate, the Company shall prepare a notice of such adjustment of the
Conversion Rate setting forth the adjusted Conversion Rate and the date on which each adjustment
becomes effective and shall mail such notice of such adjustment of the Conversion Rate to the
Holder of each Debentures at his last address appearing on the Register, within 20 calendar days
after execution thereof. Failure to deliver such notice shall not affect the legality or validity
of any such adjustment.



     (k) In any case in which this Section 10.05 provides that an adjustment shall become effective
immediately after (1) a record date for an event, (2) the date fixed for the determination of
stockholders entitled to receive a dividend or distribution pursuant to Section 10.05(a), (3) a
date fixed for the determination of stockholders entitled to receive rights or warrants pursuant to
Section 10.05(c), or (4) the Expiration Time for any tender or exchange offer pursuant to Section
10.05(f) (each a “Determination Date”), the Company may elect to defer until the occurrence of



61









 







the applicable Adjustment Event (as hereinafter defined) (x) issuing to the Holder of any Debentures
converted after such Determination Date and before the occurrence of such Adjustment Event, the
additional shares of Common Stock, if any, or other securities issuable upon such conversion by
reason of the adjustment required by such Adjustment Event over and above the Common Stock, if any,
issuable upon such conversion before giving effect to such adjustment and (y) paying to such Holder
any amount in cash in lieu of any fractional share pursuant to Section 10.03. For purposes of this
Section 10.05(k), the term “Adjustment Event” shall mean:




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




     (ii) in any case referred to in clause (2) hereof, the date any such dividend or
distribution is paid or made,




     (iii) in any case referred to in clause (3) hereof, the date of expiration of such
rights or warrants, and




     (iv) in any case referred to in clause (4) hereof, the date a sale or exchange of
Common Stock pursuant to such tender or exchange offer is consummated and becomes
irrevocable.



     (l) For purposes of this Section 10.05, 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.
The Company will not pay any dividend or make any distribution on shares of Common Stock held in
the treasury of the Company.



     (m) No adjustment to the Conversion Rate shall be made pursuant to this Section 10.05 if the
Holders of the Debentures may participate in the transaction that would otherwise give rise to
adjustment pursuant to this Section 10.05.



     SECTION 10.06 Effect of Reclassification, Consolidation, Merger or Sale
.. If any of the following events occur, namely:




	 	(a)	 	any reclassification or change of the outstanding 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 subdivision or combination),
	 
	 	(b)	 	any consolidation, merger or binding share exchange of the Company with or into
another Person, or
	 
	 	(c)	 	any sale, lease, transfer, conveyance or other disposition of all or
substantially all of the Company’s assets and those of its Subsidiaries taken as a
whole to any other Person or Persons,




as a result of which holders of Common Stock shall be entitled to receive stock, other securities
or other property or assets (including cash or any combination thereof) with respect to or in
exchange for such Common Stock, in each case, the Company or the successor or purchasing


62









 






corporation, as the case may be, shall execute with the Trustee a supplemental indenture (which
shall comply with the Trust Indenture Act as in force at the date of execution of such supplemental
indenture, if such supplemental indenture is then required to so comply) providing that each such
Debenture shall, without the consent of any Holders of Debentures, become convertible into a
Conversion Settlement Amount based on only the kind and amount of shares of stock and other
securities or property or assets (including cash or any combination thereof) (the “Applicable
Consideration”), as provided further below, that holders of shares of Common Stock received in such
reclassification, change, consolidation, merger, binding share exchange, sale, lease, transfer,
conveyance or other disposition, except that the conditions relating to conversion of Debentures
specified herein (including in Sections 10.01, 10.02 and 10.12) (modified as appropriate in the
good faith judgment of the Board of Directors to apply properly to the Applicable Consideration in
lieu of Common Stock) and the provisions of Section 10.12 relating to the settlement of the
conversion obligation upon conversion of Debentures shall
continue to apply following such transaction. In the event holders of Common Stock have the
opportunity to elect the form of consideration to be received in such transaction, the Applicable
Consideration shall consist of the consideration that a majority of the holders of Common Stock who
made such an election received in such transaction. The Company may not become a party to any such
transaction unless its terms are consistent with the foregoing. Such supplemental indenture shall
provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 10, as determined in good faith by the Company or successor or
purchasing corporation. If, in the case of any such reclassification, change, consolidation,
merger, binding share exchange, sale, lease, transfer, conveyance or other disposition, the stock
or other securities and assets receivable thereupon by a holder of Common Stock includes shares of
stock or other securities and assets of a corporation other than the successor or purchasing
corporation, as the case may be, in such reclassification, change, consolidation, merger, binding
share exchange, sale, lease, transfer, conveyance or other disposition, then such supplemental
indenture shall also be executed by such other corporation and shall contain such additional
provisions to protect the interests of the Holders of the Debentures as the Board of Directors
shall reasonably consider necessary by reason of the foregoing, including to the extent practicable
the provisions providing for the conversion rights set forth in this Article 10. Upon the
effectiveness of such transaction, a Holder of Debentures shall thereafter have the right to
convert such Debentures, at the Conversion Rate in effect immediately prior to the effectiveness of
such transaction (subject to adjustment as provided in Section 10.04 and Section 10.05), only into
cash and units of Applicable Consideration (a “unit of Applicable consideration” being, for
purposes of this Indenture, the kind and amount of Applicable Consideration which the holder of one
share of Common Stock would have received in such transaction, determined as set forth above), as
provided for in accordance with Section 10.12.




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



     The above provisions of this Section 10.06 shall similarly apply to successive
reclassifications, changes, consolidations, mergers, binding share exchanges, sales, leases,
transfers, conveyances or other dispositions.



63









 





     If this Section 10.06 applies to any event or occurrence, Section 10.05 shall not apply.
Notwithstanding this Section 10.06, if a Public Acquirer Change of Control occurs and the Company
elects to adjust its conversion obligation and the Conversion Rate pursuant to Section 10.13, the
provisions of Section 10.13 instead of this Section 10.06 shall apply to the transaction.



     SECTION 10.07 Taxes on Shares Issued
.. The issue of stock certificates on conversions of Debentures shall be made without charge to the
converting Holder of Debentures for any documentary, stamp or similar issue or transfer tax in
respect of the issue thereof. The Company shall not, however, be required to pay any such tax which
may be payable in respect of any transfer involved in the issue and delivery of stock in any name
other than that of the Holder of any Debentures converted, and the Company shall not
be required to issue or deliver any such stock certificate unless and until the Person or Persons
requesting the issue thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.



     SECTION 10.08 Reservation of Shares, Shares to be Fully Paid; Compliance with Governmental
Requirements; Listing of Common Stock
.. The Company shall provide, free from preemptive rights, out of its authorized but unissued shares
or shares held in treasury, sufficient shares of Common Stock to provide for the conversion of the
Debentures from time to time as such Debentures are presented for conversion.



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



     The Company covenants that all shares of Common Stock which may be issued upon conversion of
Debentures will upon issue be fully paid and non-assessable by the Company and free from all taxes,
liens and charges with respect to the issue thereof.



     The Company covenants that, if any shares of Common Stock to be provided for the purpose of
conversion of Debentures hereunder require registration with or approval of any governmental
authority under any federal or state law before such shares may be validly issued upon conversion,
the Company will in good faith and as expeditiously as possible, to the extent then permitted by
the rules and interpretations of the Commission (or any successor thereto), endeavor to secure such
registration or approval, as the case may be.



     The Company further covenants that, if at any time the Common Stock shall be listed on any
national securities exchange or automated quotation system, the Company will, if permitted by the
rules of such exchange or automated quotation system, list and keep listed, so long as the Common
Stock shall be so listed on such exchange or automated quotation system, all Common Stock issuable
upon conversion of the Debentures; provided that if the rules of such exchange or automated
quotation system permit the Company to defer the listing of such Common Stock until the first
conversion of the Debentures into Common Stock in accordance with the provisions of this Indenture,
the Company covenants to list such Common Stock issuable upon conversion of



64









 







the Debentures in
accordance with the requirements of such exchange or automated quotation system at such time.



     SECTION 10.09 Responsibility of Trustee
.. The Trustee and any other conversion agent shall not at any time be under any duty or
responsibility to any Holder of Debentures to determine the Conversion Rate or whether any facts
exist which may require any adjustment of the Conversion Rate, or with respect to the nature or
extent or calculation of any such adjustment when made, or with respect to the method employed, or
herein or in any supplemental indenture provided to be employed, in making the same. The Trustee
and any other conversion agent shall not be accountable with respect to the
validity or value (or the kind or amount) of any shares of Common Stock, or of any capital stock,
other securities or other assets or property, which may at any time be issued or delivered upon the
conversion of any Debentures; and the Trustee and any other conversion agent make no
representations with respect thereto. Neither the Trustee nor any conversion agent shall be
responsible for any failure of the Company to issue, transfer or deliver any shares of Common Stock
or stock certificates or other securities or property or cash upon the surrender of any Debentures
for the purpose of conversion or to comply with any of the duties, responsibilities or covenants of
the Company contained in this Article 10. Without limiting the generality of the foregoing, neither
the Trustee nor any conversion agent shall be under any responsibility to determine the correctness
of any provisions contained in any supplemental indenture entered into pursuant to Section 10.06
relating either to the kind or amount of shares of capital stock or other securities or other
assets or property (including cash) receivable by Holders of Debentures upon the conversion of
their Debentures after any event referred to in such Section 10.06 or to any adjustment to be made
with respect thereto, but, subject to the provisions of Section 9.01, may accept as conclusive
evidence of the correctness of any such provisions, and shall be protected in relying upon, the
Officers’ Certificate (which the Company shall be obligated to file with the Trustee prior to the
execution of any such supplemental indenture) with respect thereto.



     SECTION 10.10 Notice to Holders Prior to Certain Actions. In case:




	 	(a)	 	the Company shall declare a dividend (or any other distribution) on its Common
Stock that would require an adjustment in the Conversion Rate pursuant to Section
10.05; or
	 
	 	(b)	 	the Company shall authorize the granting to the holders of all or substantially
all of its Common Stock or rights or warrants to subscribe for or purchase any share of
any class or any other rights or warrants; or
	 
	 	(c)	 	of any reclassification or change of the Common Stock of the Company (other
than a subdivision or combination of its outstanding Common Stock, or a change in par
value, or from par value to no par value, or from no par value to par value), or of any
consolidation or merger or binding share exchange to which the Company is a party and
for which approval of any stockholders of the Company is required, or of the sale,
lease, transfer, conveyance or other disposition of all or substantially all of the
assets of the Company and those of its Subsidiaries taken as a whole; or




65









 






	 	(d)	 	of the voluntary or involuntary dissolution, liquidation or winding up of the
Company;




and, in the case of the events specified in clauses (a), (b) or (c), if the Debentures are
convertible at the time of or in connection with such event, the Company shall cause to be filed
with the Trustee and to be mailed to each Holder of Debentures at his address appearing on the
Register provided for in Section 2.05 of this Indenture, as promptly as possible but in any event
at least ten calendar days prior to the applicable date hereinafter specified, a notice stating (x)
the date on
which a record is to be taken for the purpose of such dividend, distribution or rights or warrants,
or, if a record is not to be taken, the date as of which the holders of Common Stock of record to
be entitled to such dividend, distribution or rights are to be determined, or (y) the date on which
such reclassification, change, consolidation, merger, binding share exchange, sale, transfer,
conveyance or other disposition, dissolution, liquidation or winding up is expected to become
effective or occur, and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other property deliverable upon
such reclassification, change, consolidation, merger, binding share exchange, sale, lease,
transfer, conveyance or other disposition, dissolution, liquidation or winding up. Failure to give
such notice, or any defect therein, shall not affect the legality or validity of such dividend,
distribution, reclassification, change, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up.




     SECTION 10.11 Stockholder Rights Plans
.. If the rights provided for in any future rights plan adopted by the Company have separated from
the shares of Common Stock in accordance with the provisions of the applicable stockholder rights
agreement so that the Holders of the Debentures would not be entitled to receive any rights in
respect of Common Stock issuable upon conversion of the Debentures, the Conversion Rate will be
adjusted (and, if applicable readjusted) as provided in Section 10.05(d). If such rights have not
separated, any shares of Common Stock delivered upon the conversion of Debentures shall be
accompanied by such rights.



     SECTION 10.12 Settlement Upon Conversion
.. Upon any conversion of Debentures, the Company will deliver to converting Holders in respect of
each $1,000 principal amount of Debentures being converted, a “Conversion Settlement Amount” equal
to the sum of the Daily Settlement Amounts for each of the 20 Trading Days during the Conversion
Settlement Averaging Period, provided that in no event shall the Company issue upon conversion of
Debentures more than 19.7571 shares of Common Stock per $1,000 principal amount of Debentures,
subject to adjustments in the same manner as and as of any date on which the Conversion Rate is
adjusted.



     Subject to the limitations described above, “Daily Settlement Amount”, for each $1,000
principal amount of Debentures, for each of the 20 Trading Days during the Conversion Settlement
Averaging Period, shall consist of:




     (i) cash equal to the lesser of $50 and the Daily Conversion Value; and




     (ii) to the extent the Daily Conversion Value exceeds $50, a number of shares of Common
Stock (or, if the Conversion Settlement Amount is then based (x) on the



66









 







Applicable
Consideration in accordance with Section 10.06, units of Applicable Consideration or (y) on
shares of Public Acquirer Common Stock in accordance with Section 10.13, shares of Public
Acquirer Common Stock) equal to, (A) the difference between the Daily Conversion Value and
$50, divided by (B) the Volume Weighted Average Price of the Common Stock (or, if the
Conversion Settlement Amount is then based (x) on the Applicable Consideration in accordance
with Section 10.06, a unit of the
Applicable Consideration or (y) on shares of Public Acquirer Common Stock in accordance
with Section 10.13, a share of the Public Acquirer Common Stock) for that day.



     “Daily Conversion Value” means, for any Trading Day, one-twentieth (1/20) of the product of
(1) the applicable Conversion Rate on that Trading Day and (2) the Volume Weighted Average Price of
the Common Stock (or, if the Conversion Settlement Amount is then based (x) on the Applicable
Consideration in accordance with Section 10.06, a unit of the Applicable Consideration or (y) on
shares of Public Acquirer Common Stock in accordance with Section 10.13, a share of the Public
Acquirer Common Stock) on such day. For the purposes of determining the Daily Conversion Value, the
following provisions shall apply: (i) if the Applicable Consideration includes securities for which
the price can be determined in a manner contemplated by the definition of “Volume Weighted Average
Price,” then the value of such securities shall be determined in accordance with the principles set
forth in such definition; (ii) if the Applicable Consideration includes other property (other than
securities as to which clause (i) applies or cash), then the value of such property shall be the
Fair Market Value of such property as determined by the Company’s Board of Directors in good faith;
and (iii) if the Applicable Consideration includes cash, then the value of such cash shall be the
amount thereof.



     The Conversion Settlement Amount will be delivered in cash and shares of Common Stock (or, if
the Conversion Settlement Amount is then based (x) on the Applicable Consideration in accordance
with Section 10.06, units of Applicable Consideration or (y) on shares of Public Acquirer Common
Stock in accordance with Section 10.13, shares of Public Acquirer Common Stock) to converting
Holders on the third Trading Day following the final Trading Day of the Conversion Settlement
Averaging Period.



     SECTION 10.13 Conversion After a Public Acquirer Change of Control.



     (a) In the event of a Public Acquirer Change of Control, the Company may, in lieu of adjusting
the Conversion Rate pursuant to Section 10.04(b) or 10.06, elect to adjust its conversion
obligation and the Conversion Rate such that from and after the Effective Date of such Public
Acquirer Change of Control, Holders of the Debentures shall be entitled, subject to the conditions
relating to conversion of Debentures specified herein (including Sections 10.01, 10.02 and 10.12))
to receive a Conversion Settlement Amount upon conversion of Debentures based on shares of Public
Acquirer Common Stock; and the Conversion Rate in effect immediately before the Public Acquirer
Change of Control shall be adjusted by multiplying it by a fraction:




     (1) the numerator of which shall be (A) in the case of a consolidation, merger or
binding share exchange, pursuant to which the Common Stock is converted solely into cash,
the value of such cash paid or payable per share of Common Stock or (B) in the



67









 







case of any
other Public Acquirer Change of Control, the average of the Closing Sale Prices of the
Common Stock for the five consecutive Trading Days prior to but excluding the Effective Date
of such Public Acquirer Change of Control; and




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



     (b) The Company shall notify Holders of its election by providing notice as set forth in
Section 10.04(b).



     (c) If the Company elects to make the adjustment to the Conversion Rate described in Section
10.13(a) in the event of a Public Acquirer Change of Control, (i) Holders of Debentures will not be
entitled to receive any Additional Shares pursuant to Section 10.04(b) as a result of such Public
Acquirer Change of Control; (ii) Section 10.06 will not apply to such transaction; and (iii) the
Company and the acquirer or other issuer of Public Acquirer Common Stock shall execute with the
Trustee a supplemental indenture (which shall comply with the Trust Indenture Act as in force at
the date of execution of such supplemental indenture, if such supplemental indenture is then
required to so comply) providing that such Debentures shall, without the consent of any Holders of
Debentures, be convertible into a Conversion Settlement Amount based on shares of Public Acquirer
Common Stock at the adjusted Conversion Rate as specified above (subject to the conditions relating
to conversion of Debentures specified herein (including Sections 10.01, 10.02 and 10.12)). Such
supplemental indenture shall provide for adjustments that shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 10, as determined in good faith by the
Company or the Public Acquirer.



     SECTION 10.14 Limitations on Foreign Ownership
.. The shares of Common Stock issuable upon conversion of the Debentures are subject to limitations
on foreign ownership as and to the extent set forth in the certificate of incorporation and bylaws
of the Company. By reason of such limitations, upon conversion of the Debentures, as and to the
extent set forth in the certificate of incorporation and bylaws of the Company, a foreign holder of
Common Stock received upon such conversion will not receive or accrue any rights with respect to
any dividends or other distributions of assets declared payable or be entitled to vote with respect
to any matter submitted to stockholders and will be subject to having such shares redeemed by the
Company for cash or for promissory notes of the Company with maturities not to exceed ten years and
bearing interest at the then-applicable rate for U.S. treasury instruments of the same tenor. Each
Debentureholder, by accepting the same, (a) agrees to and shall be bound by such limitations and
(b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate such limitations.

computed on the basis of a 360-day year of twelve 30-day months. If a payment date is not a

before the interest payment date, except as otherwise provided in the Indenture. Holders must
surrender Debentures to a Paying Agent to collect principal payments. The Company will pay
principal and interest in money of the United States of America that at the time of payment is
legal tender for payment of public and private debts. The Company shall pay interest (i) on any

or its nominee, (ii) on any Debentures in certificated form having a principal amount of less than
$2,000,000, by check mailed to the address of the Person entitled thereto as it appears in the

maintained by the Company for such purposes, which shall initially be an office or agency of the
Trustee (as defined below) and (iii) on any Debentures in certificated form having a principal
amount of $2,000,000 or more, by wire transfer in immediately available funds at the election of

Company, in whole or in part from time to time, on not less than 30 calendar days’ nor more than 60
calendar days’ prior notice, at a redemption price set forth below, plus accrued and unpaid

be redeemed in part but only in whole multiples of $1,000. If money sufficient to pay the
redemption price of and accrued interest on all Debentures (or portions thereof) to be redeemed on
the redemption date is deposited with the Paying Agent on or before the redemption date and certain
other conditions are satisfied, on and after such date interest ceases to accrue on such Debentures
(or such portions thereof) called for redemption.



7. Repurchase of Debentures at the Option of Debentureholders




     If a Fundamental Change occurs at any time prior to maturity of the Debentures, this Debenture
will be subject to a repurchase, at the option of the Holder, on a Fundamental Change Repurchase
Date, specified by the Company, that is not less than 20 calendar days nor more than 35 calendar
days after notice thereof, at a repurchase price equal to 100% of the principal amount hereof,
together with accrued and unpaid interest on this Debenture to, but excluding, the Fundamental
Change Repurchase Date; provided that if such Fundamental Change Repurchase Date falls after a
record date and on or prior the corresponding interest payment date, the accrued and unpaid
interest shall be payable to the holder of record of this Debenture on the preceding July 15 or
January 15, as the case may be. For Debentures to be so repurchased at the option of the Holder,
the Holder must deliver to the Paying Agent in accordance with the terms of the Indenture, the
Repurchase Notice containing the information specified by the Indenture, together with such
Debentures, duly endorsed for transfer, or (if the Debentures are Global Debentures) book-entry
transfer of the Debentures, prior to 5:00 p.m., New York City time, on the Fundamental Change
Repurchase Date.



     Subject to the terms and conditions of the Indenture, each Holder shall have the right, at
such Holder’s option, to require the Company to repurchase all or any portion of the Debentures
held by such Holder, on January 15, 2014, January 15, 2017 and January 15, 2022 at a repurchase
price equal to 100% of the principal amount of this Debenture, together with any accrued and unpaid
interest on this Debenture to, but excluding, the Repurchase Date, as provided in the Indenture;
provided that if such Repurchase Date falls after a record date and on or prior the corresponding
interest payment date, the accrued and unpaid interest shall be payable to the holder of record of
this Debenture on the preceding July 15 or January 15, as the case may be. To exercise such right,
a Holder shall deliver to the Paying Agent the Repurchase Notice containing the information
specified by the Indenture, together with the Debentures, duly endorsed for transfer, or (if the
Debentures are Global Debentures) book-entry transfer of the Debentures, at any time during the
period from 9:00 a.m., New York City time, on the date that is 20 Business Days prior to the
applicable Repurchase Date to 5:00 p.m., New York City time, on the applicable Repurchase Date.



     Holders have the right to withdraw any Repurchase Notice by delivering to the Paying Agent a
written notice of withdrawal at any time prior to 5:00 p.m., New York City time, on the Fundamental
Change Repurchase Date or the Repurchase Date, as applicable, all as provided in the Indenture.



8. Conversion




     Subject to and upon compliance with the provisions of the Indenture, the Holder hereof has the
right, at its option, to convert each $1,000 principal amount of this Debenture into cash



A-R-3









 







and, if applicable, Common Stock based on a Conversion Rate of 23.0216 shares of Common Stock
per $1000 principal amount of Debentures (equivalent to a Conversion Price of approximately $43.44
per share), as the same may be adjusted pursuant to the terms of the Indenture. As specified in
the Indenture, upon conversion, the Company will pay cash and shares of Common Stock, if any, based
on a Daily Conversion Value (as defined in the Indenture) calculated on a proportionate basis for
each day of the 20 Trading-Day Conversion Settlement Averaging Period (as defined in the
Indenture), subject to a maximum of 19.7571 shares of Common Stock per $1,000 principal amount of
Debentures, subject to adjustments as specified in the Indenture.



     If and only to the extent Holders elect to convert the Debentures in connection with a
Non-Stock Change of Control (as defined in the Indenture), the Company may be required to increase
the Conversion Rate applicable to such converting Debentures; provided that in the case of a
Non-Stock Change of Control constituting a Public Acquirer Change of Control (as defined in the
Indenture), the Company may, in lieu of increasing the Conversion Rate, elect to adjust the
conversion obligation and the Conversion Rate such that from and after the effective date of such
Public Acquirer Change of Control, Holders of the Debentures will be entitled to convert their
Debentures (subject to the satisfaction of certain conditions) into a number of shares of Public
Acquirer’s Common Stock (as defined in the Indenture) determined as set forth in the Indenture.



     If this Debenture (or portion hereof) is surrendered for conversion during the period from the
5:00 p.m., New York City time, on any applicable Record Date for the payment of interest to 5:00
p.m., New York City time, on the Business Day preceding the corresponding interest payment date,
this Debenture (or portion hereof being converted) must be accompanied by payment, in immediately
available funds or other funds acceptable to the Company, of an amount equal to the interest
(excluding any Additional Interest) otherwise payable on such interest payment date on the
principal amount being converted; provided that no such payment shall be required (1) if the Holder
surrenders this Debenture for conversion in connection with a redemption and the Company has
specified a redemption date that is after a Record Date and on or prior to the corresponding
interest payment date, (2) if the Holder surrenders this Debenture in connection with a Fundamental
Change and the Company has specified a Fundamental Change Repurchase Date that is after a Record
Date and on or prior to the corresponding interest payment date or (3) to the extent of any overdue
interest, if any, existing at the time of conversion with respect to this Debenture.



     No fractional shares will be issued upon any conversion of Debentures, but an adjustment and
payment in cash will be made, as provided in the Indenture, in respect of any fraction of a share
which would otherwise be issuable upon the surrender of any Debentures or Debentures for
conversion.



     A Debenture in respect of which a Holder is exercising its right to require repurchase may be
converted only if such Holder validly withdraws its election to exercise such right to require
repurchase in accordance with the terms of the Indenture.



A-R-4









 






9. Denominations, Transfer, Exchange




     The Debentures are in registered form without coupons in denominations of $1,000 and whole
multiples of $1,000. A Debentureholder may transfer or exchange Debentures in accordance with the
Indenture. Upon any transfer or exchange, the Registrar and the Trustee may require a
Debentureholder, among other things, to furnish appropriate endorsements or transfer documents and
to pay any taxes required by law or permitted by the Indenture. The Registrar need not issue,
register the transfer of, or exchange any Debentures during the period of 15 days before the
mailing of the notice of redemption, or register the transfer of or exchange any Debentures so
selected for redemption, in whole or in part, except the unredeemed portion of any Debentures being
redeemed in part.



10. Persons Deemed Owners 




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



11. Unclaimed Money




     Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay
to the Company upon written request any money held by them for the payment of principal or interest
and any shares of Common Stock or other property due in respect of converted Debentures that
remains unclaimed for two years, and, thereafter, Debentureholders entitled to the money and/or
securities must look to the Company for payment as general creditors.



12. Amendment, Waiver




     Subject to certain exceptions set forth in the Indenture, (i) the Indenture or the Debentures
may be amended without prior notice to any Debentureholder but with the written consent of the
Holders of at least a majority in aggregate principal amount of the outstanding Debentures and (ii)
any default or noncompliance with any provision may be waived with the written consent of the
Holders of at least a majority in principal amount of the outstanding Debentures. In certain
circumstances set forth in the Indenture, the Company and the Trustee may amend the Indenture or
the Debentures without the consent of any Holder of Debentures.



13. Defaults and Remedies




     If an Event of Default occurs (other than an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization) and is continuing, the Trustee or the Holders of at least
25% in principal amount of the outstanding Debentures may declare the principal of and accrued but
unpaid interest on all the Debentures to be due and payable, except as provided in the Indenture.
If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization
occurs, the principal of and interest on all the Debentures will become immediately due and payable
without any declaration or other act on the part of the Trustee or any Debentureholders. Under
certain circumstances, the Holders of a majority in principal amount of the outstanding Debentures
may rescind any such acceleration with respect to the Debentures and its consequences. No
reference herein to the Indenture and no provision of this Debenture or of the Indenture shall
impair, as among the Company and the Holder of the



A-R-5









 







Debentures, the obligation of the Company, which is absolute and unconditional, to pay the
principal of, premium, if any, on and interest on this Debenture at the place, at the respective
times, at the rate and in the coin or currency herein and in the Indenture prescribed or to convert
the Debenture as provided in the Indenture.



14. Trustee Dealings with the Company




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



15. Indenture and Debentures Solely Corporate Obligations




     No recourse for the payment of the principal of or, premium, if any, or interest on any
Debentures or for any claim based upon any Debentures or otherwise in respect thereof, and no
recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or in
any supplemental indenture or in any Debentures or because of the creation of any indebtedness
represented thereby shall be had against any incorporator, stockholder, member, manager, employee,
agent, officer, director or subsidiary, as such, past, present or future, of the Company or any of
the Company’s subsidiaries or of any successor thereto, either directly or through the Company or
any of the Company’s subsidiaries or any successor thereto, whether by virtue of any constitution,
statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being
expressly understood that all such liability is hereby expressly waived and released as a condition
of, and as a consideration for, the execution of the Indenture and the issue of the Debentures.



16. Authentication




     This Debenture shall not be valid until an authorized signatory of the Trustee (or an
authenticating agent) manually signs the certificate of authentication on the other side of this
Debenture.



17. Abbreviations




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



18. GOVERNING LAW




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



A-R-6









 





19. CUSIP and ISIN Numbers




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



20. Limitations on Foreign Ownership.




     The shares of Common Stock issuable upon conversion of the Debentures are subject to
limitations on foreign ownership as and to the extent set forth in the certificate of incorporation
and bylaws of the Company. By reason of such limitations, upon conversion of the Debentures, as
and to the extent set forth in the certificate of incorporation and bylaws of the Company, a
foreign holder of Common Stock received upon such conversion will not receive or accrue any rights
with respect to any dividends or other distributions of assets declared payable or be entitled to
vote with respect to any matter submitted to stockholders and will be subject to having such shares
redeemed by the Company for cash or for promissory notes of the Company with maturities not to
exceed ten years and bearing interest at the then-applicable rate for U.S. treasury instruments of
the same tenor. Each Debentureholder, by accepting the same, (a) agrees to and shall be bound by
such limitations and (b) authorizes and directs the Trustee on his behalf to take such action as
may be necessary or appropriate to effectuate such limitations.



     The Company will furnish to any Holder of Debentures upon written request and without charge
to the Holder a copy of the Indenture.
