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



          Section 2.04. Payments of Additional Interest. If at any time during the six months to one
year period following the Issue Date, the Company fails to timely file any document or report that
it is required to file with the Commission pursuant to Section 13 or 15(d) of the Exchange Act, as
applicable




-12-









 








(giving effect to any grace period provided by Rule 12b-25 and other than reports on Form
8-K), the Company shall make a one time payment of (1) 50 basis points on the then outstanding
aggregate principal amount of the Notes or (2) an equivalent amount for any outstanding shares of
common stock issued upon conversion of the Notes based on the aggregate principal amount of the
Notes so converted (the “Additional Interest”); provided that the Company shall have 14 days, in
the aggregate, to cure all such missed filings. Such Additional Interest will be payable, in
accordance with Section 2.03 hereof, on the Interest Payment Date following the first Record Date
after such interest becomes owing in accordance with the foregoing.




          Section 2.05. Execution, Authentication and Delivery of Notes. The Notes shall be signed in
the name and on behalf of the Company by the manual or facsimile signature of its Chief Executive
Officer, President, Treasurer, Secretary or any of its Executive or Senior Vice Presidents.




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




          Only such Notes as shall bear thereon a certificate of authentication substantially in the
form set forth on the form of Note attached as Exhibit A hereto, executed manually or by facsimile
by an authorized officer of the Trustee (or an authenticating agent appointed by the Trustee as
provided by Section 17.11), shall be entitled to the benefits of this Indenture or be valid or
obligatory for any purpose. Such certificate by the Trustee (or such an authenticating agent) upon
any Note executed by the Company shall be conclusive evidence that the Note so authenticated has
been duly authenticated and delivered hereunder and that the holder is entitled to the benefits of
this Indenture.




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




          Section 2.06. Exchange and Registration of Transfer of Notes; Restrictions on Transfer;
Depositary







          (a) The Company shall cause to be kept at the Corporate Trust Office a register (the register
maintained in such office or in any other office or agency of the Company designated pursuant to
Section 5.02 being herein sometimes collectively referred to as the “Note Register”) in which,
subject to such reasonable regulations as it may prescribe, the Company shall provide for the
registration of Notes and of transfers of Notes. Such register shall be in written form or in any
form capable of being converted into written form within a reasonable period of time. The Trustee
is hereby appointed “Note Registrar” for the purpose of registering Notes and transfers of Notes as
herein provided. The Company may appoint one or more co-registrars in accordance with Section
5.02.




          Upon surrender for registration of transfer of any Note to the Note Registrar or any
co-registrar, and satisfaction of the requirements for such transfer set forth in this Section
2.06, the Company


-13-









 







shall execute, and the Trustee shall authenticate and deliver, in the name of the
designated transferee or transferees, one or more new Notes of any authorized denominations and of
a like aggregate principal amount and bearing such restrictive legends as may be required by this
Indenture.




          Notes may be exchanged for other Notes of any authorized denominations and of a like aggregate
principal amount, upon surrender of the Notes to be exchanged at any such office or agency
maintained by the Company pursuant to Section 5.02. Whenever any Notes are so surrendered for
exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Notes that
the Noteholder making the exchange is entitled to receive, bearing registration numbers not
contemporaneously outstanding.




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




          No service charge shall be charged to the Noteholder for any exchange or registration of
transfer of Notes, but the Company or the Trustee may require payment of a sum sufficient to cover
any tax, assessments or other governmental charges that may be imposed in connection therewith as a
result of the name of the Noteholder of the new Notes issued upon such exchange or registration of
transfer of Notes being different from the name of the Noteholder of the old Notes presented or
surrendered for such exchange or registration of transfer.




          None of the Company, the Trustee, the Note Registrar or any co-registrar shall be required to
exchange or register a transfer of (i) any Notes surrendered for conversion or, if a portion of any
Note is surrendered for conversion, such portion thereof surrendered for conversion or (ii) any
Notes, or a portion of any Note, surrendered for repurchase (and not withdrawn) in accordance with
Article 16 hereof.




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




          (b) So long as the Notes are eligible for book-entry settlement with the Depositary, unless
otherwise required by law, all Notes shall be represented by one or more Notes in global form
(each, a “Global Note”) registered in the name of the Depositary or the nominee of the Depositary.
The transfer and exchange of beneficial interests in a Global Note that does not involve the
issuance of a definitive Note, shall be effected through the Depositary (but not the Trustee or the
Custodian) in accordance with this Indenture (including the restrictions on transfer set forth
herein) and the procedures of the Depositary therefor.




          (c) [Reserved.]




          (d) Every Note that bears or is required under this Section 2.06(d) to bear the legend set
forth in this Section 2.06(d) (together with any Common Stock issued upon conversion of the Notes
and required to bear the legend set forth in Section 2.06(e), collectively, the “Restricted
Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.06(d)
(including the legend set


-14-









 







forth below), unless such restrictions on transfer shall be eliminated or
otherwise waived by written consent of the Company, and the holder of each such Restricted
Security, by such holder’s acceptance thereof, agrees to be bound by all such restrictions on
transfer. As used in Section 2.06(d) and Section 2.06(e), the term “transfer” encompasses any
sale, pledge, transfer or other disposition whatsoever of any Restricted Security.




          Until the date (the “Resale Restriction Termination Date”) that is the later of (1) the date
one year after the last date of original issuance of the Notes, or such other period of time as
permitted by Rule 144 under the Securities Act or any successor provision thereto, and (2) such
later date, if any, as may be required by applicable laws, any certificate evidencing such Note
(and all securities issued in exchange therefor or substitution thereof, other than Common Stock,
if any, issued upon conversion thereof which shall bear the legend set forth in Section 2.06(e), if
applicable) shall bear a legend in substantially the following form (unless such Notes have been
transferred (i) pursuant to a registration statement that has become or been declared effective
under the Securities Act and that continues to be effective at the time of such transfer, (ii)
pursuant to the exemption from registration provided by Rule 144 or any similar provision then in
force under the Securities Act, or (iii) unless otherwise agreed by the Company in writing, with
such written agreement and notice thereof delivered to the Trustee):





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




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




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




     (A) TO PENSON WORLDWIDE, INC. (THE “COMPANY”) OR ANY SUBSIDIARY
THEREOF, OR




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




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



-15-









 






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




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



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




          Any Note (or security issued in exchange or substitution therefor) as to which such
restrictions on transfer shall have expired in accordance with their terms may, upon surrender of
such Note for exchange to the Note Registrar in accordance with the provisions of this Section
2.06, be exchanged for a new Note or Notes, of like tenor and aggregate principal amount, which
shall not bear the restrictive legend required by this Section 2.06(d). The Company shall notify
the Trustee upon the occurrence of the Resale Restriction Termination Date and promptly after a
Registration Statement with respect to the Notes or any Common Stock issued upon conversion of the
Notes has been declared effective under the Securities Act.




          Notwithstanding any other provisions of this Indenture (other than the provisions set forth in
this Section 2.06(d)), a Global Note may not be transferred as a whole or in part except (i) by the
Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or
another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such successor Depositary and (ii) for transfers of portions of a Global
Note in certificated form made upon request of a member of, or a participant in, the Depositary
(for itself or on behalf of a beneficial owner) by written notice given to the Trustee by or on
behalf of the Depositary in accordance with customary procedures of the Depositary and in
compliance with this Section.




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




          If (i) the Depositary notifies the Company at any time that the Depositary is unwilling or
unable to continue as depositary for the Global Notes and a successor depositary is not appointed
within 90 days, (ii) the Depositary ceases to be registered as a clearing agency under the Exchange
Act and a successor depositary is not appointed within 90 days or (iii) an Event of Default in
respect of the Notes has occurred and is continuing, upon the request of the beneficial owner of
the Notes, the Company will execute, and the Trustee, upon receipt of an Officers’ Certificate and
a Company Order for the authentication and delivery of Notes, will authenticate and deliver Notes
in definitive form to each such beneficial owner of the related Notes (or a portion thereof) in an
aggregate principal amount equal to the principal


-16-









 







amount of such Global Note, in exchange for such Global Note, and upon delivery of the Global
Note to the Trustee such Global Note shall be canceled.




          Definitive Notes issued in exchange for all or a part of the Global Note pursuant to this
Section 2.06(d) shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. Upon execution and authentication, the Trustee shall deliver such definitive
Notes to the Persons in whose names such definitive Notes are so registered.




          At such time as all interests in a Global Note have been converted, canceled, repurchased or
transferred, such Global Note shall be, upon receipt thereof, canceled by the Trustee in accordance
with standing procedures and instructions existing between the Depositary and the Custodian. At
any time prior to such cancellation, if any interest in a Global Note is exchanged for definitive
Notes, converted, canceled, repurchased or transferred to a transferee who receives definitive
Notes therefor or any definitive Note is exchanged or transferred for part of such Global Note, the
principal amount of such Global Note shall, in accordance with the standing procedures and
instructions existing between the Depositary and the Custodian, be appropriately reduced or
increased, as the case may be, and an endorsement shall be made on such Global Note, by the Trustee
or the Custodian, at the direction of the Trustee, to reflect such reduction or increase.




          None of the Company, the Trustee nor any agent of the Company or the Trustee will have any
responsibility or liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests of a Global Note or maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.




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





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




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



-17-









 






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




     (A) TO PENSON WORLDWIDE, INC. (THE “COMPANY”) OR ANY SUBSIDIARY
THEREOF, OR




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




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




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




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



          Any such Common Stock as to which such restrictions on transfer shall have expired in
accordance with their terms may, upon surrender of the certificates representing such shares of
Common Stock for exchange in accordance with the procedures of the Transfer Agent for the Common
Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of
Common Stock, which shall not bear the restrictive legend required by this Section 2.06(e).




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




          (g) Notwithstanding any provision of Section 2.06 to the contrary, in the event Rule 144 as
promulgated under the Securities Act (or any successor rule) is amended to change the one-year
holding period thereunder (or the corresponding period under any successor rule), from and after
receipt by the Trustee of the Officers’ Certificate and Opinion of Counsel provided for in this
Section 2.06(g), (i) each reference in Section 2.06(d) to “one year” and in the restrictive legend
set forth in such paragraph to




-18-









 








“ONE YEAR” shall be deemed for all purposes hereof to be references to such changed period,
(ii) each reference in Section 2.06(e) to “one year” and in the restrictive legend set forth in
such paragraph to “ONE YEAR” shall be deemed for all purposes hereof to be references to such
changed period and (iii) all corresponding references in the Notes (including the definition of
Resale Restriction Termination Date) and the restrictive legends thereon shall be deemed for all
purposes hereof to be references to such changed period, provided that such changes shall not
become effective if they are otherwise prohibited by, or would otherwise cause a violation of, the
then-applicable federal securities laws. The provisions of this Section 2.06(g) will not be
effective until such time as the Opinion of Counsel and Officers’ Certificate have been received by
the Trustee hereunder. This Section 2.06(g) shall apply to successive amendments to Rule 144 (or
any successor rule) changing the holding period thereunder.




          Section 2.07. Mutilated, Destroyed, Lost or Stolen Notes. In case any Note shall become
mutilated or be destroyed, lost or stolen, the Company in its discretion may execute, and upon its
written request the Trustee or an authenticating agent appointed by the Trustee shall authenticate
and deliver, a new Note, bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Note, or in lieu of and in substitution for the Note so destroyed,
lost or stolen. In every case the applicant for a substituted Note shall furnish to the Company,
to the Trustee and, if applicable, to such authenticating agent such security or indemnity as may
be required by them to save each of them harmless from any loss, liability, cost or expense caused
by or connected with such substitution, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent evidence to their satisfaction of the destruction, loss or theft of such Note
and of the ownership thereof.




          The Trustee or such authenticating agent may authenticate any such substituted Note and
deliver the same upon the receipt of such security or indemnity as the Trustee, the Company and, if
applicable, such authenticating agent may require. Upon the issuance of any substitute Note, the
Company or the Trustee may require the payment by the holder of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in relation thereto and any other
expenses connected therewith. In case any Note that has matured or is about to mature or has been
tendered for repurchase upon a Fundamental Change or is about to be converted into cash, shares of
Common Stock or a combination of cash and shares of Common Stock, as applicable, shall become
mutilated or be destroyed, lost or stolen, the Company may, in its sole discretion, instead of
issuing a substitute Note, pay or authorize the payment of or convert or authorize the conversion
of the same (without surrender thereof except in the case of a mutilated Note), as the case may be,
if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and,
if applicable, to such authenticating agent such security or indemnity as may be required by them
to save each of them harmless for any loss, liability, cost or expense caused by or connected with
such substitution, and, in every case of destruction, loss or theft, evidence satisfactory to the
Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence of their
satisfaction of the destruction, loss or theft of such Note and of the ownership thereof.




          Every substitute Note issued pursuant to the provisions of this Section 2.07 by virtue of the
fact that any Note is destroyed, lost or stolen shall constitute an additional contractual
obligation of the Company, whether or not the destroyed, lost or stolen Note shall be found at any
time, and shall be entitled to all the benefits of (but shall be subject to all the limitations set
forth in) this Indenture equally and proportionately with any and all other Notes duly issued
hereunder. To the extent permitted by law, all Notes shall be held and owned upon the express
condition that the foregoing provisions are exclusive with respect to the replacement or payment or
conversion or repurchase of mutilated, destroyed, lost or stolen Notes and shall preclude any and
all other rights or remedies notwithstanding any law or statute


-19-









 







existing or hereafter enacted to the contrary with respect to the replacement or payment or
conversion of negotiable instruments or other securities without their surrender.




          Section 2.08. Temporary Notes. Pending the preparation of Notes in certificated form, the
Company may execute and the Trustee or an authenticating agent appointed by the Trustee shall, upon
written request of the Company, authenticate and deliver temporary Notes (printed or lithographed).
Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of
the Notes in certificated form but with such omissions, insertions and variations as may be
appropriate for temporary Notes, all as may be determined by the Company. Every such temporary
Note shall be executed by the Company and authenticated by the Trustee or such authenticating agent
upon the same conditions and in substantially the same manner, and with the same effect, as the
Notes in certificated form. Without unreasonable delay the Company will execute and deliver to the
Trustee or such authenticating agent Notes in certificated form (other than any Global Note) and
thereupon any or all temporary Notes (other than any Global Note) may be surrendered in exchange
therefor, at each office or agency maintained by the Company pursuant to Section 5.02 and the
Trustee or such authenticating agent shall authenticate and deliver in exchange for such temporary
Notes an equal aggregate principal amount of Notes 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 Notes shall in all respects be entitled to the same benefits and subject to the same
limitations under this Indenture as Notes in certificated form authenticated and delivered
hereunder.




          Section 2.09. Cancellation of Notes Paid, Etc. All Notes surrendered for the purpose of
payment, repurchase, conversion, exchange or registration of transfer, shall, if surrendered to the
Company or any Paying Agent or any Note Registrar or any Conversion Agent, be surrendered to the
Trustee and promptly canceled by it, or, if surrendered to the Trustee, shall be promptly canceled
by it, and no Notes shall be issued in lieu thereof except as expressly permitted by any of the
provisions of this Indenture. The Trustee shall dispose of canceled Notes in accordance with its
customary procedures and, after such disposition, shall deliver a certificate of such disposition
to the Company, at the Company’s written request. If the Company shall acquire any of the Notes,
such acquisition shall not operate as satisfaction of the indebtedness represented by such Notes
unless and until the same are delivered to the Trustee for cancellation.




          Section 2.10. CUSIP Numbers. The Company in issuing the Notes may use “CUSIP” numbers (if
then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in all notices issued to
Noteholders as a convenience to holders of the Notes; provided, that any such notice may state that
no representation is made as to the correctness of such numbers either as printed on the Notes or
on such notice and that reliance may be placed only on the other identification numbers printed on
the Notes. The Company will promptly notify the Trustee in writing of any change in the “CUSIP”
numbers.




          Section 2.11. Additional Notes; Repurchases. The Company may, without the consent of the
Noteholders and notwithstanding Section 2.01, reopen this Indenture and issue additional Notes
hereunder with the same terms and with the same CUSIP numbers as the Notes initially issued
hereunder in an unlimited aggregate principal amount, which will form the same series with the
Notes initially issued hereunder, provided that no such additional Notes may be issued unless they
will be fungible with the original Notes for U.S. federal income tax and securities law purposes.
Prior to the issuance of any such additional Notes, the Company shall deliver to the Trustee a
Company Order, an Officers’ Certificate and an Opinion of Counsel, such Officers’ Certificate and
Opinion of Counsel to cover such matters, in addition to those required by Section 17.05, as the
Trustee shall reasonably request. The Company





-20-











 




may also from time to time repurchase the Notes in open market purchases or negotiated
transactions without prior notice to Noteholders or Trustee.

ARTICLE 4

SATISFACTION AND DISCHARGE




          Section 4.01. Satisfaction and Discharge. This Indenture shall upon request of the Company contained in an Officers’ Certificate
cease to be of further effect, and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture, when (a) (i) all Notes
theretofore authenticated and delivered (other than (x) Notes which have been destroyed, lost or
stolen and which have been replaced or paid as provided in Section 2.07 and (y) Notes for whose
payment money has theretofore been deposited in trust or segregated and held in trust by the
Company and thereafter repaid to the Company or discharged from such trust, as provided in Section
5.04(d)) have been delivered to the Trustee for cancellation; and (ii) the Company has deposited
with the Trustee or delivered to Noteholders, as applicable, after the Notes have become due and
payable, whether at the Maturity Date, any Fundamental Change Purchase Date, upon conversion or
otherwise, cash or cash and shares of Common Stock, if any (solely to satisfy the Company’s
Conversion Obligation, if applicable), sufficient to pay all of the outstanding Notes and all other
sums due payable under this Indenture by the Company; and (b) the Company has delivered to the
Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this Indenture have
been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 8.06 shall survive.




ARTICLE 5

PARTICULAR COVENANTS OF THE COMPANY




          Section 5.01. Payment of Principal, Premium, Interest and Additional Interest. The Company covenants and agrees that it will cause to be paid the principal of and
premium, if any (including the Fundamental Change Purchase Price), and accrued and unpaid interest
and Additional Interest, if any, on each of the Notes at the places, at the respective times and in
the manner provided herein and in the Notes. Each installment of accrued and unpaid interest, and
Additional Interest, if any, on the Notes, may be paid by mailing checks for the amount payable to
Noteholders entitled thereto as they shall appear on the registry books of the Company; provided
that, with respect to any Noteholder with an aggregate principal amount in excess of $1,000,000, at
the application of such holder in writing to the Trustee and Paying Agent (if different from the
Trustee) not later than the relevant Interest Record Date, accrued and unpaid interest and
Additional Interest, if any, on such holder’s Notes shall be paid by wire transfer in immediately
available funds to such holder’s account in the United States, which application shall remain in
effect until the Noteholder notifies the Trustee and Paying Agent to the contrary; provided further
that payment of accrued and unpaid interest and Additional Interest, if any, made to the Depositary
shall be paid by wire transfer in immediately available funds in accordance with such wire transfer
instructions and other procedures provided by the Depositary from time to time.



          Section 5.02. Maintenance of Office or Agency. The Company will maintain in the City of St. Paul, Minnesota or The Borough of Manhattan,
The City of New York, an office or agency where the Notes may be surrendered for registration of
transfer or exchange or for presentation for payment or repurchase (“Paying Agent”) or for
conversion (“Conversion Agent”) and where notices and



-21-









 




demands to or upon the Company in respect of the Notes and this Indenture may be served. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such office or agency. If at any time
the Company shall fail to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office or the office or agency of the Trustee in St. Paul,
Minnesota.




          The Company may also from time to time designate co-registrars, one or more other offices or
agencies where the Notes may be presented or surrendered for any or all such purposes and may from
time to time rescind such designations; provided that no such designation or rescission shall in
any manner relieve the Company of its obligation to maintain an office or agency in St. Paul,
Minnesota or The Borough of Manhattan, The City of New York, for such purposes. The Company will
give prompt written notice to the Trustee of any such designation or rescission and of any change
in the location of any such other office or agency. The terms “Paying Agent” and “Conversion
Agent” include any such additional or other offices or agencies, as applicable.



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



          Section 5.03. Appointments to Fill Vacancies in Trustee’s Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will
appoint, in the manner provided in Section 8.10, a Trustee, so that there shall at all times be a
Trustee hereunder.



          Section 5.04. Provisions as to Paying Agent.



          (a) If the Company shall appoint a Paying Agent other than the Trustee, the Company will cause
such Paying Agent to execute and deliver to the Trustee an instrument in which such agent shall

     (i) that it will hold all sums held by it as such agent for the payment of the
principal of and premium, if any, and accrued and unpaid interest and Additional Interest,

     (ii) that it will give the Trustee prompt notice of any failure by the Company to make
any payment of the principal of and premium, if any, and accrued and unpaid interest and
Additional Interest, if any, on the Notes when the same shall be due and payable; and




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



          The Company shall, on or before each due date of the principal of, or premium (including the
Fundamental Change Purchase Price), if any, or accrued and unpaid interest or Additional Interest,
if any, on the Notes, deposit with the Paying Agent a sum sufficient to pay such principal, premium
(including the Fundamental Change Purchase Price), if any, or accrued and unpaid interest or
Additional Interest, if any, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of any failure to take such action, provided that if such deposit is
made on the due date, such deposit must be received by the Paying Agent by 11:00 a.m., New York
City time, on such date.



-22-









 





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



          (c) Anything in this Section 5.04 to the contrary notwithstanding, the Company may, at any
time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other
reason, pay or cause to be paid to the Trustee all sums held in trust by the Company or any Paying
Agent hereunder as required by this Section 5.04, such sums to be held by the Trustee upon the
trusts herein contained and upon such payment by the Company or any Paying Agent to the Trustee,
the Company or such Paying Agent shall be released from all further liability with respect to such
sums.



          (d) Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of or premium (including the Fundamental Change Purchase
Price), if any, accrued and unpaid interest and Additional Interest, if any, on any Note and
remaining unclaimed for two years after such principal, premium (including the Fundamental Change
Purchase Price), interest or Additional Interest has become due and payable shall be paid to the
Company on request of the Company contained in an Officers’ Certificate, or (if then held by the
Company) shall be discharged from such trust; and the holder of such Note shall thereafter, as an
unsecured general creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the Company cause to be
published once, in a newspaper published in the English language, customarily published on each
Business Day and of general circulation in The Borough of Manhattan, The City of New York, notice
that such money remains unclaimed and that, after a date specified therein, which shall not be less
than thirty days from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Company; provided, further, that if the Notes are registered solely
in the name of the Depositary, notice to the Depositary shall be sufficient.



          Section 5.05. Existence. Subject to Article 12, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its corporate existence.



          Section 5.06. Rule 144A Information Requirement and Annual Reports.



          (a) At any time the Company is not subject to Sections 13 or 15(d) of the Exchange Act, the
Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion
thereof shall, at such time, constitute “restricted securities” within the meaning of Rule
144(a)(3) under the Securities Act, promptly provide to the Trustee and shall, upon written
request, provide to any holder, beneficial owner or prospective purchaser of such Notes or any
shares of Common Stock issued upon conversion of such Notes, the information required to be
delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such
Notes or shares of Common Stock pursuant to Rule 144A under the Securities Act. The Company shall
take such further action as any holder or beneficial owner of such Notes or such Common Stock may
reasonably request to the extent required from time to



-23-









 







time to enable such holder or beneficial
holder to sell such Notes or shares of Common Stock in accordance with Rule 144A under the
Securities Act, as such rule may be amended from time to time.



          (b) The Company shall deliver to the Trustee within three Business Days after the same is
required to be filed with the Commission, copies of the quarterly and annual reports and of the
information, documents and other reports, if any, (giving effect to any grace period provided by
Rule 12b-25) that the Company is required to file with the Commission pursuant to Section 13 or
15(d) of the Exchange Act, and, to the extent required by Section 17.08, the Company shall
otherwise comply with the requirements of Trust Indenture Act section 314(a). Any such report,
information or document that the Company files with the Commission through the Commission’s EDGAR
database shall be deemed delivered to the Trustee for purposes of this Section 5.06(b) at the time
of such filing through the EDGAR database.



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



          Section 5.07. Stay, Extension and Usury Laws. The Company covenants (to the extent that it may lawfully do so) that it shall not at any
time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any
stay, extension or usury law or other law that would prohibit or forgive the Company from paying
all or any portion of the principal of or interest on the Notes as contemplated herein, wherever
enacted, now or at any time hereafter in force, or that may affect the covenants or the performance
of this Indenture; and the Company (to the extent it may lawfully do so) hereby expressly waives
all benefit or advantage of any such law, and covenants that it will not, by resort to any such
law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will
suffer and permit the execution of every such power as though no such law had been enacted.



          Section 5.08. Compliance Certificate; Statements as to Defaults. The Company shall deliver to the Trustee within 120 days after the end of each Fiscal Year
of the Company (beginning with the Fiscal Year ending on December 31, 2009) an Officers’
Certificate stating whether or not the signer thereof has knowledge of any failure by the Company
to comply with all conditions and covenants then required to be performed under this Indenture and, if
so, specifying each such failure and the nature thereof.



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



          Section 5.09. Additional Interest. If Additional Interest is payable by the Company pursuant to Section 2.04, the Company
shall deliver to the Trustee an Officers’ Certificate, at least one Business Day before the Record
Date for such Additional Interest payment, to that effect stating (a) the amount of such Additional
Interest that is payable and (b) the date on which such interest is payable. Unless and until a
Responsible Officer of the Trustee receives at the Corporate Trust Office such a certificate, the
Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has
paid Additional Interest directly to the Persons entitled to them, the Company shall deliver to the
Trustee an Officers’ Certificate setting forth the particulars of such payment.

          Section 5.10. Further Instruments and Acts. Upon request of the Trustee, the Company will execute and deliver such further instruments

          Section 6.02. Preservation and Disclosure of Lists.

receipt of a new list so furnished.



          (b) The rights of Noteholders to communicate with other Noteholders with respect to their

          (c) Every Noteholder, by receiving and holding the same, agrees with the Company and the

          In case one or more Events of Default shall have occurred and be continuing (whatever the
reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by
operation of law or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body), then, and in each and every such case
(other than an Event of Default specified in Section 7.01(i) or Section 7.01(j) with respect to the
Company (and not solely with respect to a “significant subsidiary” (as defined in paragraphs
(w)(1), (2) and (3) of Rule 1-02 of Regulation S-X under the Exchange Act) of the Company, or a
group of Subsidiaries of the Company that in aggregate would constitute a “significant subsidiary”
of the Company), unless the principal of all of the Notes shall have already become due and
payable, either the Trustee or the holders of at least 25% in aggregate principal amount of the
Notes then outstanding determined in accordance with Section 9.04, by notice in writing to the
Company (and to the Trustee if given by Noteholders), may declare 100% of the principal of and
premium, if any, and accrued and unpaid interest and accrued and unpaid Additional Interest, if
any, on all the Notes to be due and payable immediately, and upon any such declaration the same
shall become and shall automatically be immediately due and payable, anything in this Indenture or
in the Notes contained to the contrary notwithstanding. If an Event of Default specified in
Section 7.01(i) or Section 7.01(j) with respect to the Company (and not solely with respect to a
“significant subsidiary” (as defined in paragraphs (w)(1), (2) and (3) of Rule 1-02 of Regulation
S-X under the Exchange Act) of the Company, or a group of Subsidiaries of the Company that in
aggregate would constitute a “significant subsidiary” of the Company) occurs and is continuing, the
principal of all the Notes and accrued and unpaid interest and accrued and unpaid Additional
Interest, if any, shall be immediately due and payable. This provision, however, is subject to the
conditions that if, at any time after the principal of the Notes shall have been so declared due
and payable, and before any judgment or decree for the payment of the monies due shall have been
obtained or entered as hereinafter provided, the Company shall pay or shall deposit with the
Trustee a sum sufficient to pay installments of accrued and unpaid interest and accrued and unpaid
Additional Interest, if any, upon all Notes and the principal of and premium, if any, on any and
all Notes that shall have become due otherwise than by acceleration (with interest on overdue
installments of accrued and unpaid interest and accrued and unpaid Additional Interest, if any, (to
the extent that payment of such interest is enforceable under applicable law) and on such principal
and premium, if any, at the rate borne by the Notes at such time) and amounts due to the Trustee
pursuant to Section 8.06, and if (1) rescission would not conflict with any judgment or decree of a
court of competent jurisdiction and (2) any and all Events of Defaults under this Indenture, other
than the nonpayment of principal of and



-27-









 







premium, if any, and accrued and unpaid interest and
accrued and unpaid Additional Interest, if any, on Notes that shall have become due solely by such
acceleration, shall have been cured or waived pursuant to Section 7.07, then and in every such case
the holders of a majority in aggregate principal amount of the Notes then outstanding, by written
notice to the Company and to the Trustee, may waive all Defaults or Events of Default with respect
to the Notes (other than a Default or an Event of Default resulting from a failure to repurchase
any Notes when required upon a Fundamental Change or a failure to deliver, upon conversion, cash,
shares of Common Stock or a combination of cash and shares of Common Stock, as applicable, due upon
conversion) and rescind and annul such declaration and its consequences (other than a declaration
or consequences, as the case may be, resulting from a failure to repurchase any Notes when required
upon a Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common Stock or
a combination of cash and shares of Common Stock, as applicable, due upon conversion) and such
Default (other than a Default resulting from a failure to repurchase any Notes when required upon a
Fundamental Change or a failure to deliver, upon conversion, cash, shares of Common Stock or a
combination of cash and shares of Common Stock, as applicable, due upon conversion) shall cease to
exist, and any Event of Default arising therefrom (other than a Default resulting from a failure to
repurchase any Notes when required upon a Fundamental Change or a failure to deliver, upon
conversion, cash, shares of Common Stock or a combination of cash and shares of Common Stock, as
applicable, due upon conversion) shall be deemed to have been cured for every purpose of this Indenture; but no such
waiver or rescission and annulment shall extend to or shall affect any subsequent Default or Event
of Default, or shall impair any right consequent thereon.



          Notwithstanding anything in this Indenture or in the Notes to the contrary and subject to the
succeeding paragraph, for the first 360 days immediately following any violation of any obligations
the Company may be deemed to have pursuant to (1) Section 314(a)(1) of the Trust Indenture Act, or
(2) Section 5.06(b), and the continuation thereof, the sole remedy for any such violation shall be
the accrual of additional interest on the Notes at a rate per year equal to 0.50% of the
outstanding principal amount of the Notes (“Supplementary Interest”), payable semi-annually at the
same time and in the same manner as regular interest on the Notes pursuant to Section 2.03 and
Section 5.01. In no event shall Supplementary Interest accrue at a rate per year in excess of
0.50%, regardless of the number of events or circumstances giving rise to the requirement to pay
Supplementary Interest. In addition to the accrual of Supplementary Interest, on and after the
360th day, any violation of any obligations the Company may be deemed to have pursuant to (1)
Section 314(a)(1) of the Trust Indenture Act or (2) Section 5.06(b), either the Trustee or the
Noteholders of not less than 25% in aggregate principal amount of the Notes then outstanding may
declare the principal amount of the Notes and any accrued and unpaid interest, including any
Additional Interest, through the date of such declaration, to be immediately due and payable.
Whenever in this Indenture there is mentioned, in any context, the payment of interest on, or in
respect of, any Note, such mention shall be deemed to include mention of the payment of
“Supplementary Interest” provided for in this paragraph to the extent that, in such context,
Supplementary Interest is, was or would be payable in respect thereof pursuant to the provisions of
this paragraph, and express mention of the payment of Supplementary Interest (if applicable) in any
provisions hereof shall not be construed as excluding Supplementary Interest in those provisions
hereof where such express mention is not made.



          Provided that the Company is current in all payments required herein, the preceding paragraph
shall not apply during the period between six months and one year after the original Issue Date
during which time the sole remedy for any violation of Section 5.06(b) shall be the payment of
Additional Interest.



          In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned because of such waiver or rescission and



-28-









 







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



          Section 7.02. Payments of Notes on Default; Suit Therefor. If an Event of Default described in clause (a) or (b) of Section 7.01 shall have occurred,
the Company shall, upon demand of the Trustee, pay to it, for the benefit of the holders of the
Notes, the whole amount then due and payable on the Notes for principal, premium, if any, and
interest and Additional Interest, if any, with interest on any overdue principal, premium, if any,
interest and Additional Interest, if any, at the rate borne by the Notes at such time, and, in
addition thereto, such further amount as shall be sufficient to cover any amounts due to the
Trustee under Section 8.06. If the Company shall fail to pay such amounts forthwith upon such
demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial
proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to
judgment or final decree and may enforce the same against the Company or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in
the manner provided by law out of the property of the Company or any other obligor upon the Notes,
wherever situated.



          In the event there shall be pending proceedings for the bankruptcy or for the reorganization
of the Company or any other obligor on the Notes under title 11 of the United States Code, or any
other applicable law, or in case a receiver, assignee or trustee in bankruptcy or reorganization,
liquidator, sequestrator or similar official shall have been appointed for or taken possession of
the Company or such other obligor, the property of the Company or such other obligor, or in the
event of any other judicial proceedings relative to the Company or such other obligor upon the
Notes, or to the creditors or property of the Company or such other obligor, the Trustee,
irrespective of whether the principal of the Notes shall then be due and payable as therein
expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made
any demand pursuant to the provisions of this Section 7.02, shall be entitled and empowered, by
intervention in such proceedings or otherwise, to file and prove a claim or claims for the whole
amount of principal premium, if any, and accrued and unpaid interest and accrued and unpaid
Additional Interest, if any, in respect of the Notes, and, in case of any judicial proceedings, to
file such proofs of claim and other papers or documents and to take such other actions as it may
deem necessary or advisable in order to have the claims of the Trustee (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and of the Noteholders allowed in such judicial proceedings relative to the Company or any
other obligor on the Notes, its or their creditors, or its or their property, and to collect and
receive any monies or other property payable or deliverable on any such claims, and to distribute
the same after the deduction of any amounts due the Trustee under Section 8.06; and any receiver,
assignee or trustee in bankruptcy or reorganization, liquidator, custodian or similar official is
hereby authorized by each of the Noteholders to make such payments to the Trustee, as
administrative expenses, and, in the event that the Trustee shall consent to the making of such
payments directly to the Noteholders, to pay to the Trustee any amount due it for reasonable
compensation, expenses, advances and disbursements, including agents and counsel fees, and
including any other amounts due to the Trustee under Section 8.06 hereof, incurred by it up to the
date of such distribution. To the extent that such payment of reasonable compensation, expenses,
advances and disbursements out of the estate in any such proceedings shall be denied for any
reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all
distributions, dividends, monies, securities and other property that the holders of the Notes may
be entitled to receive in such proceedings, whether in liquidation or under any plan of
reorganization or arrangement or otherwise.



-29-









 





          Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to
or accept or adopt on behalf of any Noteholder any plan of reorganization, arrangement, adjustment
or composition affecting the Noteholder or the rights of any Noteholder thereof, or to authorize
the Trustee to vote in respect of the claim of any Noteholder in any such proceeding.



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



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



          Section 7.03. Application of Monies Collected by Trustee. Any monies collected by the Trustee pursuant to this Article 7 with respect to the Notes
shall be applied in the order following, at the date or dates fixed by the Trustee for the
distribution of such monies, upon presentation of the several Notes, and stamping thereon the
payment, if only partially paid, and upon surrender thereof, if fully paid:




     First, to the payment of all amounts due the Trustee under Section 8.06;



     Second, in case the principal of the outstanding Notes shall not have become due and be

made ratably to the Persons entitled thereto;




     Third, in case the principal of the outstanding Notes shall have become due, by

this Indenture to institute any suit, action or proceeding in equity or at law upon or under or

custodian or other similar official, or for any other remedy hereunder, unless such holder

thereof, as hereinbefore provided, and unless also the holders of not less than 25% in
aggregate principal amount of the Notes then outstanding shall have made written request upon the
Trustee to institute such action, suit or proceeding in its own name as Trustee hereunder and shall
have offered to the Trustee such security or indemnity reasonably satisfactory to it against any
loss, liability or expense to be incurred therein or thereby, and the Trustee for sixty days after
its receipt of such notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding and no direction that, in the opinion of the Trustee,
is inconsistent with such written request shall have been given to the Trustee by the holders of a
majority in principal amount of the Notes outstanding within such sixty-day period pursuant to
Section 7.07; it being understood and intended, and being expressly covenanted by the taker and
holder of every Note with every other taker and holder and the Trustee that no one or more
Noteholders shall have any right in any manner whatever by virtue of or by availing of any provision of this Indenture to affect, disturb or prejudice
the rights of any other Noteholder, or to obtain or seek to obtain priority over or preference to
any other such holder, or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Noteholders (except as otherwise
provided herein). For the protection and enforcement of this Section 7.04, each and every
Noteholder and the Trustee shall be entitled to such relief as can be given either at law or in
equity.



          Notwithstanding any other provision of this Indenture and any provision of any Note, the right
of any Noteholder to receive payment of the principal of and premium, if any (including the
Fundamental Change Purchase Price upon repurchase pursuant to Section 16.02), and accrued and
unpaid interest and accrued and unpaid Additional Interest, if any, on such Note, on or after the
respective due dates expressed or provided for in such Note or in this Indenture, or to institute
suit for the enforcement of any such payment on or after such respective dates against the Company
shall not be impaired or affected without the consent of such Noteholder.



          Anything in this Indenture or the Notes to the contrary notwithstanding, the holder of any
Note, without the consent of either the Trustee or the holder of any other Note, in its own behalf
and for its own benefit, may specifically enforce, and may institute and maintain any proceeding
suitable to specifically enforce, its rights of conversion as provided herein.



          Section 7.05. Proceedings by Trustee. In case of an Event of Default the Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as are
necessary to protect and enforce any of such rights, either by suit in equity or by action at law
or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant
or agreement contained in this Indenture or in aid of the exercise of any power granted in this
Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture
or by law.

deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to
the Trustee or the holders of the Notes, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this Indenture, and no delay
or omission of the Trustee or of any holder of any of the Notes to exercise any right or power
accruing upon any Default or Event of Default shall impair any such right or power, or shall be
construed to be a waiver of any such Default or any acquiescence therein; and, subject to the
provisions of Section 7.04, every power and remedy given by this Article 7 or by law to the Trustee
or to the Noteholders may be exercised from time to time, and as often as shall be deemed
expedient, by the Trustee or by the Noteholders.

          Section 7.07. Direction of Proceedings and Waiver of Defaults by Majority of Noteholders. The holders of a majority in aggregate principal amount of the Notes at the time
outstanding determined in accordance with Section 9.04 shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on the Trustee with respect to Notes; provided, however, that (a) such
direction shall not be in conflict with any rule of law or with this Indenture, and (b) the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such direction. The
Trustee may refuse to follow any direction that it determines is unduly prejudicial to the rights
of any other holder or that would involve the Trustee in personal liability. The holders of a
majority in aggregate principal amount of the Notes at the time outstanding determined in
accordance with Section 9.04 may on behalf of the holders of all of the Notes waive any past
Default or Event of Default hereunder and its consequences except (i) a default in the payment of
premium, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on, or the
principal (including any Fundamental Change Purchase Price) of, the Notes when due that has not
been cured pursuant to the provisions of Section 7.01, (ii) a failure by the Company to deliver
cash, shares of Common Stock or a combination of cash and shares of Common Stock, as applicable,
upon conversion of the Notes or (iii) a default in respect of a covenant or provision hereof which
under Article 11 cannot be modified or amended without the consent of each holder of an outstanding
Note affected. Upon any such waiver the Company, the Trustee and the holders of the Notes shall be
restored to their former positions and rights hereunder; but no such waiver shall extend to any
subsequent or other Default or Event of Default or impair any right consequent thereon. Whenever
any Default or Event of Default hereunder shall have been waived as permitted by this Section 7.07,
said Default or Event of Default shall for all purposes of the Notes and this Indenture be deemed
to have been cured and to be not continuing; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.



          Section 7.08. Notice of Defaults. The Trustee shall, within ninety days after the occurrence and continuance of a Default of
which a Responsible Officer has actual knowledge, mail to all Noteholders as the names and
addresses of such holders appear upon the Note Register, notice of all Defaults known to a
Responsible Officer, unless such Defaults shall have been cured or waived before the giving of such
notice; and provided that, except in the case of a Default in the payment of the principal of, or
premium, if any, accrued and unpaid interest or accrued and unpaid Additional Interest, if any, on
any of the Notes, including without limiting the generality of the foregoing any Default in the
payment of any Fundamental Change Purchase Price, then in any such event the Trustee shall be
protected in withholding such notice if and so long as a committee of Responsible Officers of the
Trustee in good faith determine that the withholding of such notice is in the interests of the
Noteholders.



          Section 7.09. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder of any Note by its acceptance thereof
shall be deemed to have agreed, that any court may, in its discretion, require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit and that such court may in its discretion assess
reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in
such suit, having due regard to the merits and good faith of the claims or defenses made by such
party litigant; provided that the provisions of this Section 7.09 (to the extent permitted by law)
shall not apply to any suit instituted by the Trustee, to any suit instituted by any Noteholder, or
group of Noteholders, holding in the aggregate more than 10% in principal amount of the Notes at
the time outstanding determined in accordance with Section 9.04, or to any suit instituted by any
Noteholder for the enforcement of the payment of the principal of or premium, if any, accrued and
unpaid interest or accrued and unpaid Additional Interest, if any, on any Note (including, but not
limited to, the Fundamental Change Purchase Price with respect to



-32-









 







the Notes being repurchased as provided in this Indenture) on or after the due date expressed or provided for in such Note or
to any suit for the enforcement of the right to convert any Note in accordance with the provisions
of Article 15.



ARTICLE 8

CONCERNING THE TRUSTEE




          Section 8.01. Duties and Responsibilities of Trustee. The Trustee, prior to the occurrence of an Event of Default and after the curing or waiver
of all Events of Default that may have occurred, undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture. In case an Event of Default has occurred
(which has not been cured or waived) the Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of such person’s own
affairs; provided that if an Event of Default occurs and is continuing, the Trustee will be under
no obligation to exercise any of the rights or powers under this Indenture at the request or
direction of any of the holders unless such holders have offered to the Trustee reasonable
indemnity or security against the costs, expenses and liabilities that might be incurred by it in
compliance with such request or direction.



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




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




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




     (ii) in the absence of bad faith and willful misconduct on the part of the
Trustee, the Trustee may conclusively rely, as to the truth of the statements and
the correctness of the opinions expressed therein, upon any certificates or opinions
furnished to the Trustee and conforming to the requirements of this Indenture;




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




     (c) the Trustee shall not be liable with respect to any action taken or omitted to be
taken by it in good faith in accordance with the direction of the holders as provided under
this Indenture;




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



-33-









 






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




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




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




     (h) in the event that the Trustee is also acting as Custodian, Note Registrar, Paying
Agent, Conversion Agent or Transfer Agent hereunder, the rights and protections afforded to
the Trustee pursuant to this Article 8 shall also be afforded to such Custodian, Note
Registrar, Paying Agent, Conversion Agent or Transfer Agent.



          None of the provisions contained in this Indenture shall require the Trustee to expend or risk
its own funds or otherwise incur personal financial liability in the performance of any of its
duties or in the exercise of any of its rights or powers.



          Section 8.02. Reliance on Documents, Opinions, Etc. Except as otherwise provided in Section 8.01:




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




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




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




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



-34-









 







rity or indemnity satisfactory to it against the costs, expenses and liabilities
that may be incurred therein or thereby;




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




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




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



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



          Section 8.03. No Responsibility for Recitals, Etc. The recitals contained herein and in the Notes (except in the Trustee’s certificate of
authentication) shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Notes. The Trustee shall not be accountable
for the use or application by the Company of any Notes or the proceeds of any Notes authenticated
and delivered by the Trustee in conformity with the provisions of this Indenture.



          Section 8.04. Trustee, Paying Agents, Conversion Agents or Registrar May Own Notes. The Trustee, any Paying Agent, any Conversion Agent or Note Registrar, in its individual or
any other capacity, may become the owner or pledgee of Notes with the same rights it would have if
it were not the Trustee, Paying Agent, Conversion Agent or Note Registrar.



          Section 8.05. Monies to Be Held in Trust. All monies received by the Trustee shall, until used or applied as herein provided, be held
in trust for the purposes for which they were received. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required by law. The
Trustee shall be under no liability for interest on any money received by it hereunder except as may be agreed from
time to time by the Company and the Trustee.



          Section 8.06. Compensation and Expenses of Trustee. The Company covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, reasonable compensation for all services rendered by it hereunder in any
capacity (which shall not be limited by any provision



-35-









 







of law in regard to the compensation of a
trustee of an express trust) as mutually agreed to in writing between the Trustee and the Company,
and the Company will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably incurred or made by the Trustee in accordance with any of the
provisions of this Indenture in any capacity thereunder (including the reasonable compensation and
the expenses and disbursements of its agents and counsel and of all Persons not regularly in its
employ) except any such expense, disbursement or advance as shall have been caused by its gross
negligence, willful misconduct or bad faith. The Company also covenants to indemnify the Trustee
in any capacity under this Indenture and any other document or transaction entered into in
connection herewith (other than as holder of Notes) and its agents and any authenticating agent
for, and to hold them harmless against, any loss, claim, damage, liability or expense incurred
without gross negligence, willful misconduct or bad faith on the part of the Trustee, its officers,
directors, agents or employees, or such agent or authenticating agent, as the case may be, and
arising out of or in connection with the acceptance or administration of this trust or in any other
capacity hereunder, including the costs and expenses of defending themselves against any claim of
liability in the premises. The obligations of the Company under this Section 8.06 to compensate or
indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances
shall be secured by a senior claim to which the Notes are hereby made subordinate on all money or
property held or collected by the Trustee, except, subject to the effect of Section 7.03, funds
held in trust herewith for the benefit of the holders of particular Notes. The Trustee’s right to
receive payment of any amounts due under this Section 8.06 shall not be subordinate to any other
liability or indebtedness of the Company (even though the Notes may be so subordinated). The
obligation of the Company under this Section 8.06 shall survive the satisfaction and discharge of
this Indenture and the earlier resignation or removal or the Trustee. The indemnification provided
in this Section 8.06 shall extend to the officers, directors, agents and employees of the Trustee.



          Without prejudice to any other rights available to the Trustee under applicable law, when the
Trustee and its agents and any authenticating agent incur expenses or render services after an
Event of Default specified in Section 7.01(i) or Section 7.01(j) occurs, the expenses and the
compensation for the services are intended to constitute expenses of administration under any
bankruptcy, insolvency or similar laws.



          Section 8.07. Officers’ Certificate as Evidence. Except as otherwise provided in Section 8.01, whenever in the administration of the
provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking or omitting any action hereunder, such matter (unless other
evidence in respect thereof be herein specifically prescribed) may, in the absence of gross
negligence, willful misconduct, recklessness and bad faith on the part of the Trustee, be deemed to
be conclusively proved and established by an Officers’ Certificate delivered to the Trustee, and
such Officers’ Certificate, in the absence of gross negligence, willful misconduct, recklessness
and bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken
or omitted by it under the provisions of this Indenture upon the faith thereof.



          Section 8.08. Conflicting Interests of Trustee. After qualification of this Indenture under the Trust Indenture Act, if the Trustee has or
shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee
shall either (a) eliminate such interest within ninety days, (b) apply to the Commission for
permission to continue as Trustee or (c) resign, to the extent and in the manner provided by, and
subject to the provisions of, the Trust Indenture Act and this Indenture.



          Section 8.09. Eligibility of Trustee. There shall at all times be a Trustee hereunder which shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at
least $50,000,000. If such Person publishes reports of condition at least



-36-









 







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



          Section 8.10. Resignation or Removal of Trustee.



          (a) The Trustee may at any time resign by giving written notice of such resignation to the
Company and by mailing notice thereof to the Noteholders at their addresses as they shall appear on
the Note Register. Upon receiving such notice of resignation, the Company shall promptly appoint a
successor trustee by written instrument, in duplicate, executed by order of the Board of Directors,
one copy of which instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee. If no successor trustee shall have been so appointed and have accepted
appointment within forty-five days after the mailing of such notice of resignation to the
Noteholders, the resigning Trustee may, upon ten Business Days’ notice to the Company and the
Noteholders, petition any court of competent jurisdiction for the appointment of a successor
trustee, or any Noteholder who has been a bona fide holder of a Note or Notes for at least six
months may, subject to the provisions of Section 7.09, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor
trustee.



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




     (i) the Trustee shall fail to comply with Section 8.08 within a reasonable time after
written request therefor by the Company or by any Noteholder who has been a bona fide holder
of a Note or Notes for at least six months, or




     (ii) the Trustee shall cease to be eligible in accordance with the provisions of
Section 8.09 and shall fail to resign after written request therefor by the Company or by
any such Noteholder, or




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


then, in any such case, the Company may by a Board Resolution remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the Board of Directors,
one copy of which instrument shall be delivered to the Trustee so removed and one copy to the
successor trustee, or, subject to the provisions of Section 7.09, any Noteholder who has been a
bona fide holder of a Note or Notes for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor trustee. Such court may thereupon, after such notice,
if any, as it may deem proper and prescribe, remove the Trustee and appoint a successor trustee.




          (c) The holders of a majority in aggregate principal amount of the Notes at the time
outstanding, as determined in accordance with Section 9.04, may at any time remove the Trustee and
nominate a successor trustee that shall be deemed appointed as successor trustee unless within ten
days after notice to the Company of such nomination the Company objects thereto, in which case the
Trustee



-37-









 







so removed or any Noteholder, upon the terms and conditions and otherwise as in Section
8.10(a) provided, may petition any court of competent jurisdiction for an appointment of a
successor trustee.



          (d) Any resignation or removal of the Trustee and appointment of a successor trustee pursuant
to any of the provisions of this Section 8.10 shall become effective upon acceptance of appointment
by the successor trustee as provided in Section 8.11.



          Section 8.11. Acceptance by Successor Trustee. Any successor trustee appointed as provided in Section 8.10 shall execute, acknowledge and
deliver to the Company and to its predecessor trustee an instrument accepting such appointment
hereunder, and thereupon the resignation or removal of the predecessor trustee shall become
effective and such successor trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, duties and obligations of its predecessor hereunder, with like
effect as if originally named as trustee herein; but, nevertheless, on the written request of the
Company or of the successor trustee, the trustee ceasing to act shall, upon payment of any amounts
then due it pursuant to the provisions of Section 8.06, execute and deliver an instrument
transferring to such successor trustee all the rights and powers of the trustee so ceasing to act.
Upon request of any such successor trustee, the Company shall execute any and all instruments in
writing for more fully and certainly vesting in and confirming to such successor trustee all such
rights and powers. Any trustee ceasing to act shall, nevertheless, retain a senior claim to which
the Notes are hereby made subordinate on all money or property held or collected by such trustee as
such, except for funds held in trust for the benefit of holders of particular Notes, to secure any
amounts then due it pursuant to the provisions of Section 8.06.



          No successor trustee shall accept appointment as provided in this Section 8.11 unless at the
time of such acceptance such successor trustee shall be qualified under the provisions of Section
8.08 and be eligible under the provisions of Section 8.09.



          Upon acceptance of appointment by a successor trustee as provided in this Section 8.11, each
of the Company and the successor trustee, at the written direction and at the expense of the
Company shall mail or cause to be mailed notice of the succession of such trustee hereunder to the
Noteholders at their addresses as they shall appear on the Note Register. If the Company fails to
mail such notice within ten days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be mailed at the expense of the Company.



          Section 8.12. Succession by Merger, Etc. Any corporation or other entity into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation or other entity resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any corporation or other
entity succeeding to all or substantially all of the corporate trust business of the Trustee
(including the administration of this Indenture), shall be the successor to the Trustee hereunder
without the execution or filing of any paper or any further act on the part of any of the parties
hereto, provided that in the case of any corporation or other entity succeeding to all or
substantially all of the corporate trust business of the Trustee such corporation or other entity
shall be qualified under the provisions of Section 8.08 and eligible under the provisions of
Section 8.09.



          In case at the time such successor to the Trustee shall succeed to the trusts created by this
Indenture, any of the Notes shall have been authenticated but not delivered, any such successor to
the Trustee may adopt the certificate of authentication of any predecessor trustee or
authenticating agent appointed by such predecessor trustee, and deliver such Notes so
authenticated; and in case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or an authenticating agent



-38-









 







appointed by such successor trustee may
authenticate such Notes either in the name of any predecessor trustee hereunder or in the name of
the successor trustee; and in all such cases such certificates shall have the full force which it
is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall
have; provided, however, that the right to adopt the certificate of authentication of any
predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply
only to its successor or successors by merger, conversion or consolidation.



          Section 8.13. Limitation on Rights of Trustee as Creditor. If and when the Trustee shall be or become a creditor of the Company (or any other obligor
upon the Notes), after qualification under the Trust Indenture Act, the Trustee shall be subject to
the provisions of the Trust Indenture Act regarding the collection of the claims against the
Company (or any such other obligor).

forth in writing any action proposed to be taken or omitted by the Trustee under this Indenture and

ARTICLE 9

CONCERNING THE NOTEHOLDERS




          Section 9.01. Action by Noteholders. Whenever in this Indenture it is provided that the holders of a specified percentage in
aggregate principal amount of the Notes may take any action (including the making of any demand or
request, the giving of any notice, consent or waiver or the taking of any other action), the fact
that at the time of taking any such action, the holders of such specified percentage have joined
therein may be evidenced (a) by any instrument or any number of instruments of similar tenor
executed by Noteholders in person or by agent or proxy appointed in writing, or (b) by the record
of the Noteholders voting in favor thereof at any meeting of Noteholders duly called and held in
accordance with the provisions of Article 10, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Noteholders. Whenever the Company or the
Trustee solicits the taking of any action by the holders of the Notes, the Company or the Trustee
may fix, but shall not be required to, in advance of such solicitation, a date as the record date
for determining Noteholders entitled to take such action. The record date if one is selected shall
be not more than fifteen days prior to the date of commencement of solicitation of such action.



          Section 9.02. Proof of Execution by Noteholders. Subject to the provisions of Section 8.01, Section 8.02 and Section 10.05, proof of the
execution of any instrument by a Noteholder or its agent or proxy shall be sufficient if made in
accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in
such manner as shall be satisfactory to the Trustee. The holding of Notes shall be proved by the
Note Register or by a certificate of the Note Registrar. The record of any Noteholders’ meeting
shall be proved in the manner provided in Section 10.06.

          Section 9.03. Who Are Deemed Absolute Owners. The Company, the Trustee, any authenticating agent, any Paying Agent, any Conversion Agent
and any Note Registrar may deem the Person in whose name a Note shall be registered upon the Note
Register to be, and may treat it as, the absolute owner of such Note (whether or not such Note
shall be overdue and notwithstanding any notation of ownership or other writing thereon made by any
Person other than the Company or any Note Registrar) for the purpose of receiving payment of or on
account of the principal of, premium, if any, and (subject to Section 2.03) accrued and unpaid
interest and accrued and unpaid Additional Interest, if any, on such Note, for conversion of such
Note and for all other purposes; and neither the Company nor the Trustee nor any Paying Agent nor
any Conversion Agent nor any Note Registrar shall be affected by any notice to the contrary. All
such payments so made to any holder for the time being, or upon its order, shall be valid, and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for monies
payable upon any such Note. Notwithstanding anything to the contrary in this Indenture or the
Notes following an Event of Default, any holder of a beneficial interest in a Global Note may
directly enforce against the Company, without the consent, solicitation, proxy, authorization or
any other action of the Depositary or any other Person, such holder’s right to exchange such
beneficial interest for a Note in certificated form in accordance with the provisions of this
Indenture.



          Section 9.04. Company-Owned Notes Disregarded. In determining whether the holders of the requisite aggregate principal amount of Notes
have concurred in any direction, consent, waiver or other action under this Indenture, Notes that
are owned by the Company or by any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company shall be disregarded and deemed not to be
outstanding for the purpose of any such determination; provided that for the purposes of
determining whether the Trustee shall be protected in relying on any such direction, consent,
waiver or other action only Notes that a Responsible Officer knows are so owned shall be so
disregarded. Notes so owned that have been pledged in good faith may be regarded as outstanding
for the purposes of this Section 9.04 if the pledgee shall establish to the satisfaction of the
Trustee the pledgee’s right to so act with respect to such Notes and that the pledgee is not the
Company or a Person directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company. In the case of a dispute as to such right, any decision by the
Trustee taken upon the advice of counsel shall be full protection to the Trustee. Upon request of
the Trustee, the Company shall furnish to the Trustee promptly an Officers’ Certificate listing and
identifying all Notes, if any, known by the Company to be owned or held by or for the account of
any of the above described Persons; and, subject to Section 8.01, the Trustee shall be entitled to
accept such Officers’ Certificate as conclusive evidence of the facts therein set forth and of the
fact that all Notes not listed therein are outstanding for the purpose of any such determination.



          Section 9.05. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section
9.01, of the taking of any action by the holders of the percentage in aggregate principal amount of
the Notes specified in this Indenture in connection with such action, any holder of a Note that is
shown by the evidence to be included in the Notes the holders of which have consented to such
action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof
of holding as provided in Section 9.02, revoke such action so far as concerns such Note. Except as
aforesaid, any such action taken by the holder of any Note shall be conclusive and binding upon
such holder and upon all future holders and owners of such Note and of any Notes issued in exchange
or substitution therefor or upon registration of transfer thereof, irrespective of whether any
notation in regard thereto is made upon such Note or any Note issued in exchange or substitution
therefor or upon registration of transfer thereof.

reports of the inspectors of votes on any vote by ballot taken thereat and affidavits by one or
more Persons having knowledge of the facts setting forth a copy of the notice of the meeting and

one of the duplicates shall be delivered to the Company and the other to the Trustee to be

authorized by the resolutions of the Board of Directors and the Trustee, at the Company’s expense,
may from time to time and at any time enter into an indenture or indentures supplemental hereto for
one or more of the following purposes:





     (a) to cure any ambiguity, omission, defect or inconsistency in this Indenture or
conform the terms of the Indenture or the Notes to the description thereof in the Offering

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




          Any supplemental indenture authorized by the provisions of this Section 11.01 may be executed
by the Company and the Trustee without the consent of the holders of any of the Notes at the time

without limitation, consents obtained in connection with a purchase of, or tender offer or exchange
offer for, Notes), the Company, when authorized by the resolutions of the Board of Directors and
the Trustee, at the Company’s expense, may from time to time and at any time enter into an

provisions of this Indenture or any supplemental indenture
or of modifying in any manner the rights of the holders of the Notes; provided, however, that no

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




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




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




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

     (i) modify the ranking provisions of this Indenture in a manner that is adverse to the
holder of the Notes;


in each case without the consent of each holder of an outstanding Note affected.

the consent of Noteholders as aforesaid and subject to Section 11.05, the Trustee shall join with
the Company in the execution of such supplemental indenture unless such supplemental indenture
affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which
case the Trustee may in its discretion, but shall not be obligated to, enter into such supplemental
indenture.



          It shall not be necessary for the consent of the Noteholders under this Section 11.02 to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if
such consent shall approve the substance thereof. After an amendment under this Indenture becomes
effective, the Company shall mail to the holders a notice briefly describing such amendment.
However, the failure to give such notice to all the holders, or any defect in the notice, will not
impair or affect the validity of the amendment.



          Section 11.03.
Effect of Supplemental Indentures. Any supplemental indenture executed pursuant
to the provisions of this Article 11 shall comply with the Trust Indenture Act, as then in effect;

the Trust Indenture Act prior to the time such qualification is in fact required under the
terms of the Trust Indenture Act or this Indenture has been qualified under the Trust Indenture
Act, nor shall any such qualification constitute any admission or acknowledgment by any party to
such supplemental indenture that any such qualification is required prior to the time such qualification is in

Indenture Act. Upon the execution of any supplemental indenture pursuant to the provisions of this Article
11, this Indenture shall be and be deemed to be modified and amended in accordance therewith and

any supplemental indenture pursuant to the provisions of this Article 11 may, at the Company’s
expense, bear a notation in form approved by the Trustee as to any matter provided for in such
supplemental indenture. If the Company or the Trustee shall so determine, new Notes so modified as
to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this
Indenture contained in any such supplemental indenture may, at the Company’s expense, be prepared
and executed by the Company, authenticated by the Trustee (or an authenticating agent duly
appointed by the Trustee pursuant to Section 17.11) and delivered in exchange for the Notes then
outstanding, upon surrender of such Notes then outstanding.

ARTICLE 12

CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE




          Section 12.01. Company May Consolidate, Etc. on Certain Terms. Subject to the provisions of
Section 12.02, the Company shall not consolidate with, merge with or into, or convey, transfer or
lease its properties and assets substantially as an entirety to another Person, unless:






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




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



          Upon any such consolidation, merger, conveyance, transfer or lease the Successor Company (if
not the Company) shall succeed to, and may exercise every right and power of, the Company under
this Indenture.

assets of one or more Subsidiaries of the Company substantially as an entirety to another Person,
which properties and assets, if held by the Company instead of such Subsidiaries, would constitute
the properties and assets of the Company substantially as an entirety on a consolidated basis, shall be
deemed to be the transfer of the properties and assets of the Company substantially as an entirety
to another Person.




          Section 12.02. Successor Corporation to Be Substituted. In case of any such consolidation,
merger, conveyance, transfer or lease and upon the assumption by the Successor Company, by
supplemental indenture, executed and delivered to the Trustee and reasonably satisfactory in form

due and punctual delivery or payment, as the case may be, of any consideration due upon conversion
of the Notes and the due and punctual performance of all of the covenants and conditions of this
Indenture to be performed by the Company, such Successor Company shall succeed to and be
substituted for the Company, with the same effect as if it had been named herein as the party of
the first part. Such Successor Company thereupon may cause to be signed, and may issue either in
its own name or in the name of the Company any or all of the Notes issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the Trustee; and, upon the
order of such Successor Company instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver, or
cause to be authenticated and delivered, any Notes that previously shall have been signed and
delivered by the officers of the Company to the Trustee for authentication, and any Notes that such
Successor Company thereafter shall cause to be signed and delivered to the Trustee for that
purpose. All the Notes so issued shall in all respects have the same legal rank and benefit under
this Indenture as the Notes theretofore or thereafter issued in accordance with the terms of this
Indenture as though all of such Notes had been issued at the date of the execution hereof. In the
event of any such consolidation, merger, conveyance or transfer (but not in the case of a lease),
the Person named as the “Company” in the first paragraph of this Indenture or any successor that
shall thereafter have become such in the manner prescribed in this Article 12 may be dissolved,
wound up and liquidated at any time thereafter and, except in the case of a lease, such Person
shall be released from its liabilities as obligor and maker of the Notes and from its obligations
under this Indenture.




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




          Section 12.03. Opinion of Counsel to Be Given Trustee. The Company shall not consummate a
merger, consolidation, conveyance, transfer or lease of its properties and assets substantially as
an entirety to another Person unless the Trustee shall receive an Officers’ Certificate and an
Opinion of Counsel as conclusive evidence that any such consolidation, merger, conveyance, transfer
or lease and any such assumption and, if a supplemental indenture is required in connection with
such transaction, such supplemental indenture, complies with the provisions of this Article 12.

successor corporation or entity, either directly or through the Company or any successor corporation or
entity, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any

ARTICLE 14

[INTENTIONALLY OMITTED]




ARTICLE 15

CONVERSION OF NOTES




          Section 15.01. Conversion Privilege.




          (a) Upon compliance with the provisions of this Article 15, a Noteholder shall have the right,
at such holder’s option, to convert all or any portion (if the portion to be converted is $1,000
principal amount or an integral multiple thereof) of such Note (i) subject to satisfaction of the
conditions described in Section 15.01(b) below, at any time prior to March 1, 2014 under the
circumstances and during the periods set forth in Section 15.01(b) below, and (ii) irrespective of
the conditions described in Section 15.01(b) below, on or after March 1, 2014 and prior to the
close of business on the Business Day immediately preceding the Maturity Date, in each case, at an
initial conversion rate (the “Conversion Rate”) of 101.9420 shares of Common Stock (subject to
adjustment as provided in Section 15.04 of this Indenture) per $1,000 principal amount of Notes
(subject to the settlement provisions of Section 15.02, the “Conversion Obligation”).




          (b) (i) The Notes may be surrendered for conversion during the five Business Day period
immediately after any five consecutive Trading Day period (the “Measurement Period”) in which the
Trading Price per $1,000 principal amount of Notes for each day of such Measurement Period was less
than 98% of the product of the then-applicable Conversion Rate on such Trading Day and the Last
Reported Sale Price of the Common Stock on such Trading Day. The Trading Prices shall be
determined by the Trustee pursuant to this clause and the definition of Trading Price set forth in
this Indenture. The Company shall provide written notice to the Trustee of the three independent
nationally recognized securities dealers selected by the Company pursuant to the definition of
Trading Price, along with appropriate contact information for each. The Trustee shall have no
obligation to determine the Trading Price of the Notes unless requested by the Company, and the
Company shall have no obligation to make such request unless a Noteholder provides the Company with
reasonable evidence that the Trading Price per $1,000 principal amount of the Notes would be less
than 98% of the product of the then-applicable Conversion Rate and the Last Reported Sale Price of
the Common Stock at such time, at which time the Company shall instruct the Trustee to determine
the Trading Price of the Notes beginning on the next Trading Day and on each successive Trading Day
until the Trading Price per Note is greater than or equal to 98% of the product of the
then-applicable Conversion Rate and the Last Reported Sale Price of the Common Stock on such
Trading Day. If the Company does not, when obligated to, instruct the Trustee to determine the
Trading Price of the Notes as provided in the preceding sentence, or if the Company gives such
instruction to the Trustee, and the Trustee fails to make such determination, then the Trading
Price per $1,000 principal amount of Notes will be deemed to be less than 98% of the product of the
Last Reported Sale Price of the Common Stock and the then-applicable Conversion Rate. If the
Trading Price condition




-47-









 







set forth above has been met, the Company shall so notify the Noteholders,
the Trustee and the Conver sion Agent. If, at any time after the Trading Price condition set forth
above has been met, the Trading Price per $1,000 principal amount of Notes is greater than 98% of
the product of the then-applicable Conversion Rate and the Last Reported Sale Price of the Common
Stock on such Trading Day, the Company shall so notify the holders of the Notes, the Trustee and the
Conversion Agent. In either case, the Company shall promptly publish a notice indicating that the
Trading Price condition set forth above has been met or, at any time after the Trading Price condition set
forth above has been met, that the Trading Price per $1,000 principal amount of Notes is greater
than 98% of the product of the then-applicable Conversion Rate and the Last Reported Sale Price of
the Common Stock on the relevant Trading Day, as the case may be, in a newspaper of general
circulation in The City of New York or publish such information on its website or through such
other public medium as the Company may use at that time.





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




     (A) distribute to all or substantially all holders of its Common Stock rights, options
or warrants entitling them, for a period of not more than sixty calendar days from the
declaration date of such distribution, to subscribe for or purchase its Common Stock, at a
price per share less than the Last Reported Sale Price of the Common Stock for the Trading
Day immediately preceding the declaration date for such distribution; or




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


then, in each case, the Company shall notify through the Trustee all holders of the Notes and the
Conversion Agent not less than thirty-five Business Days prior to the Ex-Dividend Date for such
distribution. Once the Company has given such notice, the Notes may be surrendered for conversion
at any time until the earlier of (1) the close of business on the Business Day immediately prior to
such Ex-Dividend Date and (2) the Company’s announcement that such distribution will not take
place, even if the Notes are not otherwise convertible at such time.




          (iii) In the event of a Fundamental Change, a Noteholder may surrender Notes for conversion at
any time from and after the thirty-fifth Business Day prior to the anticipated effective date of
such Fundamental Change until the Business Day immediately preceding the Fundamental Change
Purchase Date corresponding to such Fundamental Change. The Company shall use commercially
reasonable efforts to give notice of the anticipated effective date of any Fundamental Change as
promptly as practicable after the Company first determines the anticipated effective date of such
Fundamental Change, but in any event at least thirty-five Business Days prior to such anticipated
effective date.




          (iv) The Notes may be surrendered for conversion in any Fiscal Quarter after the Fiscal
Quarter ending September 30, 2009, and only during such Fiscal Quarter, if the Last Reported Sale
Price of the Common Stock for at least twenty Trading Days in a period of thirty consecutive
Trading Days ending on the last Trading Day of the immediately preceding Fiscal Quarter is equal to
or more than 120% of the then-applicable Conversion Price on the last day of such preceding Fiscal
Quarter (such price, the “Conversion Trigger Price”). The Conversion Agent, on behalf of the
Company, shall determine at the beginning of each Fiscal Quarter commencing after September 30,
2009 whether the Notes

may be surrendered for conversion in accordance with this clause (iv) and
shall notify the Company and the Trustee.




          Section 15.02. Conversion Procedure.





          (a) [Reserved].




          (b) Subject to this Section 15.02 and Section 15.12, upon any conversion of any Note, the
Company shall deliver to converting Noteholders, in respect of each $1,000 principal amount of
Notes being converted, solely cash, solely shares of Common Stock or a combination of cash and
Common Stock (the “Settlement Amount”), at its election, as set forth in this Section 15.02.




     (i) All conversions after March 1, 2014 will be settled using the same Settlement
Method.




     (ii) Prior to March 1, 2014, the Company will elect (or be deemed to have elected) the
same Settlement Method for all conversions occurring on any given Conversion Date. Except
for any conversions that occur on or after March 1, 2014, the Company need not elect the
same Settlement Method with respect to conversions that occur on different Trading Days.




     (iii) If, in respect of any Conversion Date (or the period beginning on, but excluding,
March 1, 2014 and ending on, and including, the Business Day immediately preceding the
Maturity Date, as the case may be), the Company elects to deliver a notice (the “Settlement
Notice”) of the relevant Settlement Method in respect of such Conversion Date (or such
period, as the case may be), the Company, through the Trustee, shall deliver such Settlement
Notice to converting Noteholders no later than the second Trading Day immediately following
the relevant Conversion Date. Such Settlement Notice shall specify whether the Company
shall satisfy its Conversion Obligation by (A) delivering solely shares of Common Stock, (B)
paying solely cash or (C) paying and delivering, as the case may be, a combination of cash
and shares of Common Stock. In the case of an election to pay and deliver, as the case may
be, a combination of cash and shares of Common Stock, the relevant Settlement Notice shall
indicate the Specified Dollar Amount. If the Company does not deliver a Settlement Notice,
the Company will be deemed to have elected to deliver a combination of cash and shares of
Common Stock in respect of its Conversion Obligation, and the Specified Dollar Amount shall
be deemed to be equal to $1,000. If the Company delivers a Settlement Notice electing to
pay and deliver, as the case may be, a combination of cash and shares of Common Stock in
respect of its Conversion Obligation but does not indicate a Specified Dollar Amount in such
Settlement Notice, the Specified Dollar Amount shall be deemed to be equal to $1,000.




     (iv) The Settlement Amount in respect of any conversion of Notes shall be computed as
follows:



     (A) if the Company elects to satisfy its Conversion Obligation in respect of
such conversion by delivering solely Common Stock, the Company will deliver to the
converting Noteholder a number of shares of Common Stock equal to (1) the aggregate
principal amount of Notes to be converted, divided by $1,000, multiplied by (2) the
then-applicable Conversion Rate;




-49-









 








     (B) if the Company elects to satisfy its Conversion Obligation in respect of
such conversion by paying solely cash, the Company shall pay to the converting Noteholder
cash in an amount per $1,000 principal amount of Notes being converted
equal to the sum of the Daily Conversion Values for each of the thirty consecutive
Trading Days during the related Cash Settlement Averaging Period; and




     (C) if the Company elects to satisfy its Conversion Obligation in respect of
such conversion by paying and delivering, as the case may be, a combination of cash
and shares of Common Stock, the Company shall pay and deliver to Noteholders, as the
case may be, in respect of each $1,000 principal amount of Notes being converted, a
Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the
thirty consecutive Trading Days during the related Cash Settlement Averaging Period.





     (v) The Company will also deliver to each converting Noteholder cash in lieu of
fractional shares of Common Stock as set forth pursuant to clause (l) below.




     (vi) The Daily Settlement Amounts (if applicable) and the Daily Conversion Values (if
applicable) shall be determined by the Company promptly following the last day of the Cash
Settlement Averaging Period. Promptly after such determination of the Daily Settlement
Amounts or the Daily Conversion Values, as the case may be, and the amount of cash
deliverable in lieu of fractional shares (if any), the Company shall notify the Trustee and
the Conversion Agent of the Daily Settlement Amounts or the Daily Conversion Values, as the
case may be, and the amount of cash deliverable in lieu of fractional shares of Common
Stock. The Trustee and the Conversion Agents shall have no responsibility for any such
determination.




          (c) [Reserved.]



          (d) Before any holder of a Note shall be entitled to convert the same as set forth above, such
holder shall (i) in the case of a Global Note, comply with the procedures of the Depositary in
effect at that time and, if required, pay funds equal to interest payable on the next Interest
Payment Date to which such holder is not entitled as set forth in Section 15.02(j) and, if
required, all transfer or similar taxes, if any, and (ii) in the case of a Note issued in
certificated form, (1) complete and manually sign and deliver an irrevocable notice to the
Conversion Agent in the form on the reverse of such certificated Note (or a facsimile thereof)
(Exhibit B hereto) (a “Notice of Conversion”) at the office of the Conversion Agent and shall state
in writing therein the principal amount of Notes to be converted and the name or names (with
addresses) in which such holder wishes the certificate or certificates for any shares of Common
Stock, if any, to be delivered upon settlement of the Conversion Obligation to be registered, (2)
surrender such Notes, duly endorsed to the Company or in blank (and accompanied by appropriate
endorsement and transfer documents), at the office of the Conversion Agent, (3) if required, pay
funds equal to interest payable on the next Interest Payment Date to which such holder is not
entitled as set forth in Section 15.02(j), (4) if required, furnish appropriate endorsements and
transfer documents, and (5) if required, pay all transfer or similar taxes, if any as set forth in
Section 15.02(g). The Trustee (and if different, the relevant Conversion Agent) shall notify the
Company of any conversion pursuant to this Article 15 on the date of such conversion. No Notice of
Conversion with respect to any Notes may be surrendered by a holder thereof if such holder has also
delivered a Fundamental Change Purchase Notice to the Company in respect of such Notes and not
validly withdrawn such Fundamental Change Purchase Notice in accordance with Section 16.03.





-50-









 








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




          (e) A Note shall be deemed to have been converted immediately prior to the close of business
on the date (the “Conversion Date”) that the holder has complied with the requirements set forth in
clause (d). The Company shall pay and deliver, as the case may be, the cash and/or shares of
Common Stock due in respect of its Conversion Obligation on the third Trading Day immediately
following the relevant Conversion Date, if the Company elects to satisfy the related Conversion
Obligation solely in shares of Common Stock, or by the third Trading Day immediately following the
last Trading Day of the Cash Settlement Averaging Period, in the case of any other Settlement
Method. If any shares of Common Stock are due to converting Noteholders, the Company shall issue
or cause to be issued, and deliver to the Conversion Agent or to such Noteholder, or such
Noteholder’s nominee or nominees, certificates or a book-entry transfer through the Depositary for
the number of full shares of Common Stock to which such Noteholder shall be entitled in
satisfaction of such Conversion Obligation.




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




          (g) If a holder submits a Note for conversion, the Company shall pay all stamp and other
duties, if any, that may be imposed by the United States or any political subdivision thereof or
taxing authority thereof or therein with respect to the issuance of shares of Common Stock, if any,
upon the conversion. However, the holder shall pay any such tax that is due because the holder
requests any shares of Common Stock to be issued in a name other than the holder’s name. The
Conversion Agent may refuse to deliver the certificates representing the shares of Common Stock
being issued in a name other than the holder’s name until the Trustee receives a sum sufficient to
pay any tax that will be due because the shares are to be issued in a name other than the holder’s
name. Nothing herein shall preclude any tax withholding required by law or regulations.




          (h) Except as provided in Section 15.04, no adjustment shall be made for dividends on any
shares issued upon the conversion of any Note as provided in this Article.




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




          (j) Upon conversion, a Noteholder shall not receive any separate cash payment for accrued and
unpaid interest and Additional Interest, if any, except as set forth below. The Company’s
settlement of the Conversion Obligations as described above shall be deemed to satisfy its
obligation to pay the principal amount of the Note and accrued and unpaid interest and Additional
Interest, if any, to, but not including, the Conversion Date. As a result, accrued and unpaid
interest and Additional Interest, if any, to, but not including, the Conversion Date shall be
deemed to be paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the
preceding sentence, if Notes are converted after the close of business on an Interest Record Date,
holders of such Notes as of the close of business on the Interest Record Date will receive the
interest and Additional Interest, if any, payable on such Notes on the corre-




-51-









 








sponding Interest Payment Date notwithstanding the conversion. Notes surrendered for conversion during the period
from the close of business on any Interest Record Date to the opening of business on the
corresponding Interest Payment Date must be accompanied by payment of an amount equal to the
interest and Additional Interest, if any, payable on the Notes so converted; provided, however,
that no such payment shall be required (1) if the Company has specified a Fundamental Change
Purchase Date that is after a Interest Record Date but on or prior to the corresponding Interest
Payment Date, (2) to the extent of any Defaulted Interest, if any, existing at the time of
conversion with respect to such Note or (3) if the Notes are surrendered for conversion after the
close of business on the Interest Record Date immediately preceding the Maturity Date. Except as
described above, no payment or adjustment will be made for accrued and unpaid interest and
Additional Interest, if any, on converted Notes.




          (k) The Person in whose name the certificate for any shares of Common Stock delivered upon
conversion is registered shall be treated as a stockholder of record as of the close of business on
the relevant Conversion Date (if the Company elects to satisfy the related Conversion Obligation
solely in shares of Common Stock) or the last Trading Day of the related Cash Settlement Averaging
Period (in the case of any other Settlement Method), as the case may be; provided, however, if such
Conversion Date or such last Trading Day of the Cash Settlement Averaging Period occurs on any date
when the stock transfer books of the Company shall be closed, such occurrence shall not be
effective to constitute the Person or Persons entitled to receive any such shares of Common Stock
due upon conversion as the record holder or holders of such shares of Common Stock on such date,
but such occurrence shall be effective to constitute the Person or Persons entitled to receive such
shares of Common Stock as the record holder or holders thereof for all purposes at the close of
business on the next succeeding day on which such stock transfer books are open. Upon conversion
of Notes, such Person shall no longer be a Noteholder.




          (l) For each Note surrendered for conversion, if the Company has elected to deliver a
combination of cash and shares of Common Stock in respect of its Conversion Obligation, the number
of full shares that shall be issued upon conversion thereof shall be computed on the basis of the
aggregate Daily Settlement Amounts for the applicable Cash Settlement Averaging Period and any
fractional shares remaining after such computation shall be paid in cash. If more than one Note
shall be surrendered for conversion at one time by the same holder, the number of full shares that
shall be issued upon conversion thereof shall be computed on the basis of the aggregate principal
amount of the Notes (or specified portions thereof) so surrendered. The Company shall not issue
fractional shares of Common Stock upon conversion of Notes. Instead, the Company shall pay cash in
lieu of fractional shares based on the Daily VWAP on the relevant Conversion Date (if the Company
elects to satisfy its Conversion Obligation solely in shares of Common Stock) or based on the Daily
VWAP on the last Trading Day of the relevant Cash Settlement Averaging Period (in the case of any
other Settlement Method).




          Section 15.03. Increased Conversion Rate Applicable to Certain Notes Surrendered in Connection
with Make-Whole Fundamental Changes.




          (a) Notwithstanding anything herein to the contrary (other than Section 15.12), the Conversion
Rate applicable to each Note that is surrendered for conversion, in accordance with this Article
15, at any time from, and including, the effective date of a Make-Whole Fundamental Change until,
and including, the close of business on the Business Day immediately prior to the related
Fundamental Change Purchase Date corresponding to such Make-Whole Fundamental Change, shall be
increased to an amount equal to the Conversion Rate that would, but for this Section 15.03,
otherwise apply to such Note pursuant to this Article 15, plus an amount equal to the Make-Whole
Conversion Rate Adjustment.





-52-











 





          As used herein, “Make-Whole Conversion Rate Adjustment” shall mean, with respect to a
Make-Whole Fundamental Change, the amount set forth in the following table that corresponds to the
effective date of such Make-Whole Fundamental Change (the “Effective Date”) and the Stock Price for
such Make-Whole Fundamental Change, all as determined by the Company:

     provided, however, that:




     (i) if the actual Stock Price of such Make-Whole Fundamental Change is between two
Stock Prices listed in the table above under the column titled “Stock Price,” or if the
actual Effective Date of such Make-Whole Fundamental Change is between two Effective Dates
listed in the table above in the row immediately below the title “Effective Date,” then the
Make-Whole Conversion Rate Adjustment for such Make-Whole Fundamental Change shall be
determined by the Company by linear interpolation between the Make-Whole Conversion Rate
Adjustment set forth for such higher and lower Stock Prices, and the earlier and later
Effective Dates based on a 365 day year, as applicable;




     (ii) if the actual Stock Price of such Make-Whole Fundamental Change is greater than
$30.00 per share (subject to adjustment in the same manner as the Stock Price as provided in
clause (iii) below), or if the actual Stock Price of such Make-Whole Fundamental Change is
less than $8.53 per share (subject to adjustment in the same manner as the Stock Price as
provided in clause (iii) below), then the Make-Whole Conversion Rate Adjustment shall be
equal to zero and this Section 15.03 shall not require the Company to increase the
Conversion Rate with respect to such Make-Whole Fundamental Change;




     (iii) if an event occurs that requires, pursuant to this Article 15 (other than solely
pursuant to this Section 15.03), an adjustment to the Conversion Rate, then, on the date and
at the time such adjustment is so required to be made, each price set forth in the table
above under the column titled “Stock Price” shall be deemed to be adjusted so that such
Stock Price, at and after such time, shall be equal to the product of (1) such Stock Price
as in effect immediately before such adjustment to such Stock Price and (2) a fraction whose
numerator is the Conversion Rate in effect immediately before such adjustment to the
Conversion Rate and whose denominator is the Conversion Rate to be in effect, in accordance
with this Article 15, immediately after such adjustment to the Conversion Rate;




     (iv) [Reserved];



-53-









 






     (v) each Make-Whole Conversion Rate Adjustment set forth in the table above shall be
adjusted in the same manner in which, and for the same events for which, the Conversion Rate
is to be adjusted pursuant to Section 15.04; and




     (vi) in no event will the total number of shares of Common Stock issuable upon
conversion of the Notes exceed 117.2333 per $1,000 principal amount of Notes, subject to
adjustment in the same manner as the Conversion Rate pursuant to Section 15.04 (the “Maximum
Conversion Rate”).



          (b) As soon as practicable after the Company determines the anticipated Effective Date of any
proposed Make-Whole Fundamental Change, but in any event at least thirty-five Business Days prior
to such anticipated Effective Date, the Company shall make commercially reasonable efforts to mail
to each Noteholder, the Trustee and the Conversion Agent written notice of, and shall issue a press
release indicating, and publicly announce, through a public medium that is customary for such
announcements, and publish on the Company’s website, the anticipated effective date of such
proposed Make-Whole Fundamental Change. Each such press release notice, announcement and
publication shall also state that in connection with such Make-Whole Fundamental Change, the
Company shall increase, in accordance herewith, the Conversion Rate applicable to Notes entitled as
provided herein to such increase (along with a description of how such increase shall be calculated
and the time periods during which Notes must be surrendered in order to be entitled to such
increase). No later than the actual Effective Date of each Make-Whole Fundamental Change, the
Company shall mail to each Noteholder, the Trustee and the Conversion Agent written notice of, and
shall issue a press release indicating, and publicly announce, through a public medium that is
customary for such announcements, and publish on the Company’s website, such Effective Date and the
amount by which the Conversion Rate has been so increased.




          Nothing in this Section 15.03 shall prevent an adjustment to the Conversion Rate pursuant to
Section 15.04 in respect of a Make-Whole Fundamental Change.




          Section 15.04. Adjustment of Conversion Rate. The Conversion Rate shall be adjusted from time to time by the Company as follows:





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



CR’= CR0 x OS’




OS0




	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

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

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






-54-









 






	 	 	 	 	 
	OS0

	 	=
	 	the number of shares of Common Stock outstanding
immediately prior to the open of business on the
Ex-Dividend Date for such dividend or
distribution, or the open of business on the
effective date of such share split or share
combination, as the case may be; and
	 
	 	 	 	 
	OS’

	 	=
	 	the number of shares of Common Stock outstanding
immediately after such dividend or distribution,
or the effective date of such share split or share
combination, as the case may be.






          Such adjustment shall become effective immediately after the opening of business on the
Ex-Dividend Date for such dividend or distribution, or the effective date for such share split or
share combination. If any dividend or distribution of the type described in this Section 15.04(a)
is declared but not so paid or made, or the outstanding shares of Common Stock are not split or
combined, as the case may be, the Conversion Rate shall be immediately readjusted, effective as of
the date the Board of Directors determines not to pay such dividend or distribution, or split or
combine the outstanding shares of Common Stock, as the case may be, to the Conversion Rate that
would then be in effect if such dividend, distribution, share split or share combination had not
been declared or announced.




          (b) In case the Company shall distribute to all or substantially all holders of its Common
Stock any rights, options or warrants entitling them for a period of not more than sixty days after
the declaration date of such distribution to subscribe for or purchase shares of the Common Stock,
at a price per share less than the Last Reported Sale Price of the Common Stock on the Trading Day
immediately preceding the declaration date for such distribution, the Conversion Rate shall be
adjusted based on the following formula:




CR’= CR0 × OS1+ X




OS0+Y




	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

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

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

	 	=
	 	the number of shares of the Common Stock that are
outstanding immediately prior to the open of
business on the Ex-Dividend Date for such
distribution;
	 
	 	 	 	 
	OS1 

	 	=
	 	the number of shares of the Common Stock that are
outstanding at the close of business on the date
of such distribution;
	 
	 	 	 	 
	X

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

	 	=
	 	the number of shares of the Common Stock equal to
the aggregate price payable to exercise such
rights, options or warrants, divided by the
average of the Last Reported Sale Prices of
Common Stock over the ten consecutive Trading Day
period ending on the






-55-









 






	 	 	 	 	 
	 

	 	 	 	Trading Day immediately
preceding the Ex-Dividend Date relating to such
distribution of such rights, options or warrants.






          Such adjustment shall be successively made whenever any such rights, options or warrants are
distributed and shall become effective immediately after the opening of business on the Ex-Dividend
Date for such distribution. The Company shall not issue any such rights, options or warrants in
respect of shares of the Common Stock held in treasury by the Company. To the extent that
shares of the Common Stock are not delivered after the expiration of such rights, options or
warrants, the Conversion Rate shall be readjusted to the Conversion Rate that would then be in
effect had the adjustments made upon the issuance of such rights, options or warrants been made on
the basis of delivery of only the number of shares of Common Stock actually delivered. If such
rights, options or warrants are not so issued, the Conversion Rate shall again be adjusted to be
the Conversion Rate that would then be in effect if such Ex-Dividend Date for such distribution had
not been fixed.




          In determining whether any rights, options or warrants entitle the holders to subscribe for or
purchase shares of the Common Stock at less than such Last Reported Sale Price of the Common Stock,
and in determining the aggregate offering price of such shares of the Common Stock, there shall be
taken into account any consideration received by the Company for such rights, options or warrants
and any amount payable on exercise or conversion thereof, the value of such consideration, if other
than cash, to be determined by the Board of Directors. In no event shall the Conversion Rate be
decreased pursuant to this Section 15.04(b).




          (c) In case the Company shall distribute shares of its Capital Stock, evidences of its
indebtedness or other of its assets or property other than (i) dividends or distributions covered
by Section 15.04(a) and Section 15.04(b), (ii) dividends or distributions paid exclusively in cash,
and (iii) Spin-Offs to which the provisions set forth below in this Section 15.04(c) shall apply
(any of such shares of Capital Stock, indebtedness, or other asset or property hereinafter in this
Section 15.04(c) called the “Distributed Property”), to all or substantially all holders of its
Common Stock, then, in each such case the Conversion Rate shall be adjusted based on the following
formula:




CR’ = CR0 ×      SP0     




SP0-FMV




	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

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

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

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

	 	=
	 	the fair market value (as determined by the Board
of Directors) of the shares of Capital Stock,
evidences of indebtedness, assets or property
distributed with respect to each outstanding share
of the Common Stock as of the open of business on
the Ex-Dividend Date for such distribution.






-56-









 






          Such adjustment shall become effective immediately prior to the opening of business on the
Ex-Dividend Date for such distribution; provided that if “FMV” as set forth above is equal to or
greater than “SP0” as set forth above, in lieu of the foregoing adjustment, adequate
provision shall be made so that each Noteholder shall receive on the date on which the Distributed
Property is distributed to holders of Common Stock, for each $1,000 principal amount of Notes the
amount of Distributed Property
such holder would have received had such holder owned a number of shares of Common Stock equal
to the Conversion Rate on the Record Date for such distribution. If such 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. If the Board of Directors
determines “FMV” for purposes of this Section 15.04(c) by reference to the actual or when issued
trading market for any securities, it must in doing so consider the prices in such market over the
same period used in computing the Last Reported Sale Prices of the Common Stock over the ten
consecutive Trading Day period ending on the Trading Day immediately preceding the Ex-Dividend Date
for such distribution.




          With respect to an adjustment pursuant to this Section 15.04(c) where there has been a
dividend or other distribution on the Common Stock of shares of Capital Stock of any class or
series, or similar equity interest, of or relating to a Subsidiary or other business unit of the
Company (a “Spin-Off”), the Conversion Rate in effect immediately before the close of business on
the tenth Trading Day immediately following, and including, the effective date of the Spin-Off will
be increased based on the following formula:




CR’ = CR0 × FMV0 + MP0




MP0




	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect immediately prior
to the close of business on the tenth Trading Day
immediately following, and including, the
effective date of the Spin-Off;
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect immediately after
the close of business on the tenth Trading Day
immediately following, and including, the
effective date of the Spin-Off;
	 
	 	 	 	 
	FMV0

	 	=
	 	the average of the Last Reported Sale Prices of
the Capital Stock or similar equity interest
distributed to holders of the Common Stock
applicable to one share of the Common Stock over
the first ten consecutive Trading Day period
immediately following, and including, the
effective date of the Spin-Off; and
	 
	 	 	 	 
	MP0

	 	=
	 	the average of the Last Reported Sale Prices of
the Common Stock over the first ten consecutive
Trading Day period immediately following and
including the effective date of the Spin-Off.






          The adjustment to the Conversion Rate under the preceding paragraph shall become effective at
the close of business on the tenth Trading Day immediately following, and including, the effective
date of the Spin-Off; provided that, for purposes of determining the Conversion Rate, in respect of
any conversion during the ten Trading Days immediately following, and including, the effective date
of any Spin-Off, references in the portion of this Section 15.04(c) related to Spin-Offs to ten
Trading Days shall be deemed replaced with such lesser number of Trading Days as have elapsed
between the effective date of such Spin-Off and the Conversion Date for such conversion.

          Subject in all respects to Section 15.10, rights, options or warrants distributed by the
Company to all holders of its Common Stock entitling the holders thereof to subscribe for or
purchase shares of the Company’s Capital Stock, including Common Stock (either initially or under
certain circumstances), which rights, options or warrants, until the occurrence of a specified
event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of the Common
Stock; (ii) are not exercisable; and (iii) are also issued in respect of future issuances of the Common
Stock, shall be
deemed not to have been distributed for purposes of this Section 15.04 (and no adjustment to the
Conversion Rate under this Section 15.04 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
15.04(c). If any such right, option or warrant, including any such existing rights, options or
warrants distributed prior to the date of this Indenture, are subject to events, upon the
occurrence of which such rights, options or warrants become exercisable to purchase different
securities, evidences of indebtedness or other assets, then the date of the occurrence of any and
each such event shall be deemed to be the date of distribution and Ex-Dividend Date with respect to
new rights, options or warrants with such rights (and a termination or expiration of the existing
rights, options or warrants without exercise by any of the holders thereof). In addition, in the
event of any distribution (or deemed distribution) of rights, options or warrants, or any Trigger
Event or other event (of the type described in the preceding sentence) with respect thereto that
was counted for purposes of calculating a distribution amount for which an adjustment to the
Conversion Rate under this Section 15.04 was made, (1) in the case of any such rights, options or
warrants that shall all have been redeemed or repurchased without exercise by any holders thereof,
the Conversion Rate shall be readjusted upon such final redemption or repurchase to give effect to
such distribution or Trigger Event, as the case may be, as though it were a cash distribution,
equal to the per share redemption or repurchase price received by a holder or holders of Common
Stock with respect to such rights, options or warrants (assuming such holder had retained such
rights or warrants), made to all holders of Common Stock as of the date of such redemption or
repurchase, and (2) in the case of such rights, options or warrants that shall have expired or been
terminated without exercise by any holders thereof, the Conversion Rate shall be readjusted as if
such rights, options and warrants had not been issued.




          For purposes of this Section 15.04(c), Section 15.04(a), and Section 15.04(b), any dividend or
distribution to which this Section 15.04(c) is applicable that also includes shares of Common
Stock, or rights, options or warrants to subscribe for or purchase shares of Common Stock to which
Section 15.04(b) applies (or both), shall be deemed instead to be (1) a dividend or distribution of
the evidences of indebtedness, assets or shares of capital stock other than such shares of Common
Stock or rights, options or warrants to which Section 15.04(c) applies (and any Conversion Rate
adjustment required by this Section 15.04(c) with respect to such dividend or distribution shall
then be made) immediately followed by (2) a dividend or distribution of such shares of Common Stock
or such rights, options or warrants (and any further Conversion Rate adjustment required by Section
15.04(a) and Section 15.04(b) with respect to such dividend or distribution shall then be made),
except (A) the Ex-Dividend Date of such dividend or distribution shall be substituted as “the
Ex-Dividend Date,” “the Ex-Dividend Date relating to such distribution of such rights, options or
warrants” and “the Ex-Dividend Date for such distribution” within the meaning of Section 15.04(a)
and Section 15.04(b) and (B) any shares of Common Stock included in such dividend or distribution
shall not be deemed “outstanding immediately prior to the Ex-Dividend Date for such dividend or
distribution, or the effective date of such share split or share combination, as the case may be”
within the meaning of Section 15.04(a) or “outstanding immediately prior to the Ex-Dividend Date
for such dividend or distribution” within the meaning of Section 15.04(b).




          In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(c).




-58-









 








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




CR’ = CR0 ×    SP0   




SP0-C




	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

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

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

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

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






          Such adjustment shall become effective immediately after the opening of business on the
Ex-Dividend Date for such dividend or distribution; provided that if “C” as set forth above is
equal to or greater than “SP0” as set forth above, in lieu of the foregoing adjustment,
adequate provision shall be made so that each Noteholder shall have the right to receive on the
date on which the relevant cash dividend or distribution is distributed to holders of Common Stock,
for each $1,000 principal amount of Notes, the amount of cash such holder would have received had
such holder owned a number of shares equal to the Conversion Rate on the Record Date for such
distribution. 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.




          For the avoidance of doubt, for purposes of this Section 15.04(d), in the event of any
reclassification of the Common Stock, as a result of which the Notes become convertible into more
than one class of Common Stock, if an adjustment to the Conversion Rate is required pursuant to
this Section 15.04(d), references in this Section to one share of Common Stock or Last Reported
Sale Price of one share of Common Stock shall be deemed to refer to a unit or to the price of a
unit consisting of the number of shares of each class of Common Stock into which the Notes are then
convertible equal to the numbers of shares of such class issued in respect of one share of Common
Stock in such reclassification. The above provisions of this paragraph shall similarly apply to
successive reclassifications.




          In no event shall the Conversion Rate be decreased pursuant to this Section 15.04(d).




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




CR’ = CR0×  AC+(SP’xOS’)




OS0×SP’




-59-









 





	 	 	 	 	 
	where
	 	 	 	 
	 
	 	 	 	 
	CR0

	 	=
	 	the Conversion Rate in effect at the close of
business on the Trading Day next succeeding the
date such tender or exchange offer expires;
	 
	 	 	 	 
	CR’

	 	=
	 	the Conversion Rate in effect at the open of
business on first day following the Trading Day
next succeeding the date such tender or exchange
offer expires;
	 
	 	 	 	 
	AC

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

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

	 	=
	 	the number of shares of Common Stock outstanding
immediately after the date such tender or exchange
offer expires (after giving effect to such tender
offer or exchange offer); and
	 
	 	 	 	 
	SP’

	 	=
	 	the Last Reported Sale Prices of Common Stock on
the Trading Day next succeeding the date such
tender or exchange offer expires.






          Such adjustment shall become effective at the close of business on the Trading Day next
succeeding the date such tender or exchange offer expires. 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 or all or any portion of 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 or had been made only in respect of
the purchases that had been effected. In no event shall the Conversion Rate be decreased pursuant
to this Section 15.04(e).




          (f) The term “Record Date” shall mean, with respect to any dividend, distribution or other
transaction or event in which the holders of Common Stock (or other security) 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).




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




          (h) Notwithstanding this Section 15.04 or any other provision of this Indenture or the Notes,
if any Conversion Rate adjustment becomes effective, or any Ex-Dividend Date for any issuance,
dividend or distribution (relating to a required Conversion Rate adjustment) occurs, during the
period beginning on, and including, the open of business on a Conversion Date and ending on, and
including, (x)





-60-











 




the close of business on the third Trading Day immediately following the relevant Conversion
Date (if the Company elects to satisfy the related Conversion Obligation solely in shares of Common
Stock) or (y) the close of business on the last Trading Day of a related Cash Settlement Averaging
Period (in the case of any other Settlement Method), the Board of Directors shall make adjustments
to the Conversion Rate and the amount of cash or number of shares of Common Stock issuable upon
conversion of the Notes, as the case may be, as is be necessary or appropriate to effect the intent
of this Section 15.04 and the other provisions of Article 15 and to avoid unjust or inequitable
results, as determined in good faith by the Board of Directors. Any adjustment made pursuant to
this Section 15.04(h) shall apply in lieu of the adjustment or other term that would otherwise be
applicable.




          (i) In addition to those required by clauses (a), (b), (c), (d) and (e) of this Section 15.04,
and to the extent permitted by applicable law and subject to the applicable rules of The NASDAQ
Global Select Market, the Company from time to time may increase the Conversion Rate by any amount
for a period of at least twenty Business Days if the Board of Directors determines that such
increase would be in the Company’s best interest. In addition, the Company may also (but is not
required to) increase the Conversion Rate to avoid or diminish any income tax to holders of Common
Stock or rights to purchase Common Stock in connection with any dividend or distribution of shares
(or rights to acquire shares) or similar event. Whenever the Conversion Rate is increased pursuant
to the preceding sentence, the Company shall provide to the holder of each Note at its last address
appearing on the Note Register provided for in Section 2.06 a notice of the increase at least
fifteen days prior to the date the increased Conversion Rate takes effect, and such notice shall
state the increased Conversion Rate and the period during which it will be in effect.




          (j) (i)The applicable Conversion Rate will not be adjusted except as described in Section
15.04 above. Without limiting the foregoing, no adjustments will be made:





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




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




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




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




     (e) for accrued and unpaid interest, including Additional Interest, if any.




     (ii) For any transactions described in this Section 15.04 if Noteholders participate
(as a result of holding the Notes, and at the same time as holders of Common Stock
participate) in such transactions as if such Noteholders held a number shares of Common
Stock equal to the Conversion Rate at the time such adjustment would be required, multiplied
by the principal amount (expressed in thousands) of Notes held by such Noteholder, without
having to convert their Notes, no adjustment will be made.



-61-









 





          (k) All calculations and other determinations under this Article 15 shall be made by the
Company and shall be made to the nearest one-ten thousandth (1/10,000) of a share.




          (l) Whenever the Conversion Rate is adjusted as herein provided, 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 without inquiry that the last Conversion Rate of
which it has knowledge is still in effect. Promptly after delivery of such certificate, the
Company shall prepare a notice of such adjustment of the Conversion Rate setting forth the adjusted
Conversion Rate and the date on which each adjustment becomes effective and shall mail such notice
of such adjustment of the Conversion Rate to the holder of each Note at its last address appearing
on the Note Register provided for in Section 2.06 of this Indenture, within ten days of the
effective date of such adjustment. Failure to deliver such notice shall not affect the legality or
validity of any such adjustment.




          (m) For purposes of this Section 15.04, 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.




          Section 15.05. Shares to Be Fully Paid. The Company shall provide, free from preemptive
rights, out of its authorized but unissued shares or shares held in treasury, sufficient shares of
Common Stock to provide for conversion of the Notes from time to time as such Notes are presented
for conversion.




          Section 15.06. Effect of Reclassification, Consolidation, Merger or Sale. Upon the occurrence
of (i) any reclassification or change of the outstanding shares of Common Stock (other than a
change in par value, or from par value to no par value, or from no par value to par value, or as a
result of a split, subdivision or combination covered by Section 15.04(a)), (ii) any consolidation,
merger or combination involving the Company, or (iii) any sale or conveyance of all or
substantially all of the property and assets of the Company to any other Person, in each case as a
result of which holders of Common Stock shall be entitled to receive cash, securities or other
property or assets with respect to or in exchange for such Common Stock (any such event a “Merger
Event”), then:





     (a) the Company or the successor or purchasing Person, as the case may be, shall
execute with the Trustee a supplemental indenture (which shall comply with the Trust
Indenture Act as in force at the date of execution of such supplemental indenture if such
supplemental indenture is then required to so comply) permitted under Section 11.01(f)
providing for the conversion and settlement of the Notes as set forth in this Indenture.
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 15. If, in the case
of any Merger Event, the Reference Property 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, combination, sale or
conveyance, 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 Notes as the Board of Directors shall reasonably consider necessary by



-62-









 







reason of the foregoing, including to the extent required by the Board of Directors and
practicable the provisions providing for the repurchase rights set forth in Article 16
herein.




     In the event the Company shall execute a supplemental indenture pursuant to this
Section 15.06, the Company shall promptly file with the Trustee an Officers’ Certificate
briefly stating the reasons therefore, the kind or amount of cash, securities or property or
asset that will comprise the Reference Property after any such Merger Event, any adjustment
to be made with respect thereto and that all conditions precedent have been complied with,
and shall promptly mail notice thereof to all Noteholders. The Company shall cause notice
of the execution of such supplemental indenture to be mailed to each Noteholder, at its
address appearing on the Note Register provided for in this Indenture, within twenty days
after execution thereof. Failure to deliver such notice shall not affect the legality or
validity of such supplemental indenture.




     (b) Notwithstanding the provisions of Section 15.02(b), and subject to the provisions
of Section 15.01 and Section 15.03, at and after the effective time of such Merger Event,
(i) the right to convert each $1,000 principal amount of Notes into cash, shares of Common
Stock or a combination of cash and shares of Common Stock at the Company’s election as set
forth in Section 15.02 will be changed to a right to convert such Note into cash, the kind
and amount of shares of stock, securities or other property or assets (including cash or any
combination thereof) that a holder of a number of shares of Common Stock equal to the
Conversion Rate immediately prior to such transaction would have owned or been entitled to
receive (the “Reference Property”) or a combination of cash and Reference Property at the
Company’s election and (ii) the related Conversion Obligation shall be settled as set forth
under clause (c) below, it being understood and agreed that for purposes of Section
15.01(b), references therein to “the Last Reported Sale Price of the Common Stock” shall be
deemed at and after the effective time of such Merger Event to be references to “the Last
Reported Sale Price of a unit of Reference Property comprised of the kind and amount of
shares of stock, securities or other property or assets (including cash or any combination
thereof) that a holder of one share of Common Stock immediately prior to such Merger Event
would have owned or been entitled to receive based on the Weighted Average Consideration.”
The Company shall not become a party to any Merger Event unless its terms are consistent
with this Section 15.06. None of the foregoing provisions shall affect the right of a
holder of Notes to convert its Notes into cash, shares of Common Stock or a combination of
cash and shares of Common Stock, as applicable, as set forth in Section 15.01 and Section
15.02 prior to the effective date of such Merger Event.




     (c) With respect to each $1,000 principal amount of Notes surrendered for conversion
after the effective date of any such Merger Event, the Company’s Conversion Obligation shall
be settled in cash or units of Reference Property, at the Company’s election, in accordance
with Section 15.02(b) as follows:




     (i) (A) if the Company elects to satisfy its Conversion Obligation in respect
of such conversion by delivering solely Reference Property, the Company shall
deliver to the converting Noteholder a number of units of Reference Property (each
such unit comprised of the kind and amount of shares of stock, securities or other
property or assets (including cash or any combination thereof) that a holder of one
share of Common Stock immediately prior to such Merger Event would have owned or
been entitled to receive based on the Weighted Average Consideration) equal to (1)
the aggregate principal amount of Notes to be converted, divided by $1,000,
multiplied by (2) the then-applicable Conversion Rate; (B) if the Company elects to
satisfy its Conversion Obligation in re-



-63-









 







spect of such conversion by paying solely cash, the Company shall pay to the
converting Noteholder cash in an amount, per $1,000 principal amount of Notes equal
to the sum of the Daily Conversion Values for each of the thirty consecutive Trading
Days during the related Cash Settlement Averaging Period, such Daily Conversion
Values determined as if the reference to “the Daily VWAP of the Common Stock” in
definition thereof were instead a reference to “the Daily VWAP of a unit of
Reference Property comprised of the kind and amount of shares of stock, securities
or other property or assets (including cash or any combination thereof) that a
holder of one share of Common Stock immediately prior to such Merger Event would
have owned or been entitled to receive based on the Weighted Average Consideration”;
and (C) if the Company elects to satisfy its Conversion Obligation through delivery
of a combination of cash and Reference Property, the Company shall deliver in
respect of each $1,000 principal amount of Notes being converted, a Settlement
Amount equal to the sum of the Daily Settlement Amounts for each of the thirty
consecutive Trading Days during the Cash Settlement Averaging Period for such Note,
such Daily Settlement Values determined as if the reference to “the Daily VWAP of
the Common Stock” in definition of Daily Conversion Value and Daily Share Amount
were instead a reference to “the Daily VWAP of a unit of Reference Property
comprised of the kind and amount of shares of stock, securities or other property or
assets (including cash or any combination thereof) that a holder of one share of
Common Stock immediately prior to such Merger Event would have owned or been
entitled to receive based on the Weighted Average Consideration.”




     (ii) The Company will deliver the cash in lieu of fractional units of Reference
Property as set forth pursuant to Section 15.02(l) (provided that the amount of such
cash shall be determined as if references in such Section to “the Last Reported Sale
Price of the Common Stock” were instead a reference to “the Last Reported Sale Price
of a unit of Reference Property composed of the kind and amount of shares of stock,
securities or other property or assets (including cash or any combination thereof)
that a holder of one share of Common Stock immediately prior to such Merger Event
would have owned or been entitled to receive based on the Weighted Average
Consideration”).




     (iii) The Daily Settlement Amounts (if applicable) and Daily Conversion Values
(if applicable) shall be determined by the Company promptly following the last day
of the Cash Settlement Averaging Period.




     (iv) For purposes of this Section 15.06, the “Weighted Average Consideration”
shall mean the weighted average of the types and amounts of consideration received
by the holders of the Common Stock entitled to receive cash, securities or other
property or assets with respect to or in exchange for such Common Stock in any
Merger Event who affirmatively make such an election.




     (v) The Company shall notify the holders of the Weighted Average Consideration
as soon as practicable after the Weighted Average Consideration is determined.




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

          Section 15.07. Certain Covenants.




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




          (b) The Company covenants that, if any shares of Common Stock to be provided for the purpose
of conversion of Notes 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, to the extent then permitted by the rules and interpretations of the Commission,
secure such registration or approval, as the case may be.




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




          Section 15.08. Responsibility of Trustee. The Trustee and any other Conversion Agent shall
not at any time be under any duty or responsibility to any Noteholder to determine the Conversion
Rate (or any adjustment thereto) or whether any facts exist that may require any adjustment
(including any increase) of the Conversion Rate, or with respect to the nature or extent or
calculation of any such adjustment when made, or with respect to the method employed, or herein or
in any supplemental indenture provided to be employed, in making the same. The Trustee and any
other Conversion Agent shall not be accountable with respect to the validity or value (or the kind
or amount) of any shares of Common Stock, or of any securities, property or cash that may at any
time be issued or delivered upon the conversion of any Note; and the Trustee and any other
Conversion Agent make no representations with respect thereto. Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Company to issue, transfer or deliver
any shares of Common Stock or stock certificates or other securities or property or cash upon the
surrender of any Note for the purpose of conversion or to comply with any of the duties,
responsibilities or covenants of the Company contained in this Article. Without limiting the
generality of the foregoing, neither the Trustee nor any Conversion Agent shall be under any
responsibility to determine the correctness of any provisions contained in any supplemental
indenture entered into pursuant to Section 15.06 relating either to the kind or amount of shares of
stock or securities or property (including cash) receivable by Noteholders upon the conversion of
their Notes after any event referred to in such Section 15.06 or to any adjustment to be made with
respect thereto, but, subject to the provisions of Section 8.01, may accept (without any
independent investigation) 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. Neither the Trustee nor the Conversion Agent shall be responsible for determining whether
any event contemplated by Section 15.01(b) has occurred that makes the Notes eligible for
conversion or no longer eligible therefor until the Company has delivered to the Trustee and the
Conversion Agent the notices referred to in Section 15.01(b) with respect to the commencement or
termination of such conversion rights, on which notices the Trustee and the Conversion Agent may
conclusively rely, and the Company agrees to deliver such notices to the Trustee and the Conversion
Agent immediately after the occurrence of any such event or at such other times as shall be
provided for in Section 15.01(b).

          Section 15.09. 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 15.04; or




     (b) the Company shall authorize the granting to all of the holders of its Common Stock
of rights, options or warrants to subscribe for or purchase any share of any class or any
other rights, options or warrants; or




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




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


the Company shall cause to be filed with the Trustee and to be mailed to each Noteholder at its
address appearing on the Note Register, provided for in Section 2.06 of this Indenture, as promptly
as possible but in any event at least twenty days prior to the applicable date hereinafter
specified, a notice stating (i) the date on which a record is to be taken for the purpose of such
dividend, distribution or rights, options 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 (ii) the date on which such reclassification, consolidation,
merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective or
occur, and the date as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their Common Stock for securities or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up.
Failure to give such notice, or any defect therein, shall not affect the legality or validity of
such dividend, distribution, reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding-up.




          Section 15.10. Stockholder Rights Plans. To the extent that the Company has a stockholder
rights plan in effect upon conversion of the Notes, each share of Common Stock, if any, issued upon
such conversion shall be entitled to receive the appropriate number of rights, if any, and the
certificates representing the Common Stock issued upon such conversion shall bear such legends, if
any, in each case as may be provided by the terms of any such stockholder rights plan, as the same
may be amended from time to time. If at the time of conversion, however, the rights have separated
from the shares of Common Stock in accordance with the provisions of the applicable stockholder
rights agreement so that the holders of the Notes would not be entitled to receive any rights in
respect of Common Stock, if any, issuable upon conversion of the Notes, the Conversion Rate will be
adjusted at the time of separation as if the Company has distributed to all holders of Common
Stock, shares of Capital Stock of the Company, evidence of indebtedness or assets as provided in
Section 15.04(c), subject to readjustment in the event of the expiration, termination or redemption
of such rights.




          Section 15.11.
Exchange in Lieu of Conversion.




          (a) When a holder surrenders its Notes for conversion, the Company may, at its election,
direct the Conversion Agent to surrender, on or prior to the second Business Day following the
relevant Conversion Date, such Notes to a financial institution designated by the Company (the
“Designated


-66-









 







Institution”) for exchange in lieu of conversion. In order to accept any Notes surrendered
for conversion for exchange in lieu of conversion, the Designated Institution must agree to timely
deliver, in exchange for such Notes, the shares of Common stock and/or cash that would otherwise be
due upon conversion as described in Section 15.02 above and in respect of which the Company has
given notice to converting Noteholders. If the Company makes the election described above, the
Company shall, by the close of business on the second Business Day following the relevant
Conversion Date as part of its Settlement Notice, notify the holder surrendering its Notes for
conversion that it has made such election. In addition, the Company shall concurrently notify the
Designated Institution of the Settlement Method (and, if applicable, the Specified Dollar Amount)
that the Company has elected with respect to such conversion and the relevant deadline for delivery
of the consideration due upon conversion. Any Notes exchanged by the Designated Institution will
remain outstanding.




          (b) If the Designated Institution agrees to accept any Notes for exchange but does not timely
deliver the related consideration due upon conversion to the Conversion Agent, or if the Designated
Institution does not accept such Notes for exchange, the Company shall, within the time period
specified in Section 15.02(e), convert such Notes into cash and/or shares of Common Stock, as
applicable in accordance with the provisions of Section 15.02.




          (c) For the avoidance of doubt, in no event will the Company’s designation of a Designated
Institution pursuant to this Section 15.11 require the Designated Institution to accept any Notes
for exchange.




          Section 15.12. Limit on Issuance of Shares of Common Stock upon Conversion. Notwithstanding
anything contained elsewhere in this Indenture, in no event will the aggregate number of shares of
Common Stock issuable upon conversion of the Notes exceed 19.99% of the Common Stock outstanding as
of June 3, 2009 (which is equivalent to issuing upon conversion approximately 84.4992 shares per
$1,000 principal amount of Notes (the “Conversion Rate Cap”) and upon any conversion of the Notes,
the Company shall deliver cash or cash and shares of Common Stock, as the case may be, in respect
of its Conversion Obligation, based upon a Specified Dollar Amount equal to $1,000 (but with the
maximum number of Shares required to be issued in connection with such conversion being subject to
the Conversion Rate Cap), unless on the Conversion Date, the Company has received stockholder
approval to issue a number of Additional Shares equal to at least the Maximum Conversion Rate in
effect at the time of any such conversion with respect to each outstanding Note (in which chase,
the Conversion Rate Cap shall be increased to such Maximum Conversion Rate (and the Company shall
provide written notice thereof to the Conversion Agent) and, from and after the date such notice is
provided to the Conversion Agent, the Company will be entitled to settle its Conversion Obligation
in any of the means described in Section 15.02).




          If an event occurs that would otherwise result in an increase in the Conversion Rate above the
Conversion Rate Cap, if and to the extent required by the shareholder approval rules or listing
standards of any national or regional securities exchange that are applicable to the Company at the
time any Notes are converted hereunder, the Company will either obtain stockholder approval of any
issuance of Common Stock upon conversion of the Notes in excess of such limitations or deliver cash
in lieu of any shares of Common Stock otherwise deliverable upon conversions in excess of such
limitations (based on the Last Reported Sale Price of the Company’s Common Stock on the Trading Day
immediately prior to the relevant Conversion Date).

          Section 16.01. [Reserved.]




          Section 16.02. Repurchase at Option of Holders upon a Fundamental Change.




          (a) If there shall occur a Fundamental Change at any time prior to the Maturity Date, then
each Noteholder shall have the right, at such holder’s option, to require the Company to repurchase
for cash all of such holder’s Notes, or any portion thereof that is an integral multiple of $1,000
principal amount, on the date (the “Fundamental Change Purchase Date”) specified by the Company
that is not less than twenty Business Days and not more than sixty Business Days after the date of
the Fundamental Change Company Notice (as defined below) at a repurchase price equal to 100% of the
principal amount thereof, together with accrued and unpaid interest, including unpaid Additional
Interest, if any, thereon to, but excluding, the Fundamental Change Purchase Date (the “Fundamental
Change Purchase Price”), unless the Fundamental Change Purchase Date is after an Interest Record
Date and on or prior to the related Interest Payment Date, in which case interest accrued to the
Interest Payment Date will be paid to holders of the Notes as of the preceding Interest Record Date
and the Fundamental Change Purchase Price payable to the holder surrendering the Note for
repurchase pursuant to this Article 16 shall be equal to the principal amount of Notes subject to
repurchase. Repurchases of Notes under this Section 16.02 shall be made, at the option of the
holder thereof, upon:





     (i) delivery to the Company and the Paying Agent by a holder of a duly completed notice
(the “Fundamental Change Purchase Notice”) in the form set forth on the reverse of the Note
as Exhibit C thereto on or prior to the Business Day immediately preceding the Fundamental
Change Purchase Date; and




     (ii) delivery or book-entry transfer of the Notes to the Paying Agent at any time after
delivery of the Fundamental Change Purchase Notice (together with all necessary
endorsements) at the Corporate Trust Office of the Paying Agent in The Borough of Manhattan,
such delivery being a condition to receipt by the holder of the Fundamental Change Purchase
Price therefor; provided that such Fundamental Change Purchase Price shall be so paid
pursuant to this Section 16.02 only if the Note so delivered to the Paying Agent shall
conform in all respects to the description thereof in the related Fundamental Change
Purchase Notice.




     The Fundamental Change Purchase Notice shall state:




	 	(A)	 	if certificated, the certificate numbers of Notes to be
delivered for repurchase;
	 
	 	(B)	 	the portion of the principal amount of Notes to be repurchased,
which must be $1,000 or an integral multiple thereof; and
	 
	 	(C)	 	that the Notes are to be repurchased by the Company pursuant to
the applicable provisions of the Notes and the Indenture;




provided, however, that if the Notes are not in certificated form, the Fundamental Change Purchase
Notice must comply with appropriate Depositary procedures.




-68-









 








          Any repurchase by the Company contemplated pursuant to the provisions of this Section 16.02
shall be consummated by the payment of the Fundamental Change Purchase Price on the later of the
Fundamental Change Purchase Date and the time of the book-entry transfer or delivery of the Note as
described in Section 16.04(a).




          Notwithstanding anything herein to the contrary, any holder delivering to the Paying Agent the
Fundamental Change Purchase Notice contemplated by this Section 16.02 shall have the right to
withdraw, in whole or in part, such Fundamental Change Purchase Notice at any time prior to the
close of business on the Business Day immediately preceding the Fundamental Change Purchase Date by
delivery of a written notice of withdrawal to the Paying Agent in accordance with Section 16.03
below.




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




          (b) On or before the twentieth day after the occurrence of the effective date of a Fundamental
Change, the Company shall mail or cause to be mailed to all holders of record of the Notes, the
Trustee, the Paying Agent and the Conversion Agent a notice (the “Fundamental Change Company
Notice”) of the occurrence of the effective date of the Fundamental Change and of the repurchase
right at the option of the holders arising as a result thereof. Such mailing shall be by first
class mail. Simultaneously with the providing of such notice, the Company will also publish a
notice containing the information set forth in the Fundamental Change Company Notice in a newspaper
of general circulation in The City of New York or publish such information on the Company’s website
or through such other public medium as the Company may use at that time. Each Fundamental Change
Company Notice shall specify:





     (i) the events causing the Fundamental Change;




     (ii) the effective date of the Fundamental Change;




     (iii) the last date on which a holder may exercise the repurchase right pursuant to
this Article 16;




     (iv) the Fundamental Change Purchase Price;




     (v) the Fundamental Change Purchase Date;




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




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




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




     (ix) that the holder must exercise the repurchase right on or prior to the close of
business on the Business Day immediately preceding the Fundamental Change Purchase Date (the
“Fundamental Change Expiration Time”);



-69-









 






     (x) that the holder shall have the right to withdraw any Notes surrendered prior to the
Fundamental Change Expiration Time; and




     (xi) the procedures that holders must follow to require the Company to repurchase their
Notes.



          No failure of the Company to give the foregoing notices and no defect therein shall limit the
Noteholders’ repurchase rights or affect the validity of the proceedings for the repurchase of the
Notes pursuant to this Section 16.02.




          (c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of
the holders upon a Fundamental Change if the principal amount of the Notes has been accelerated,
and such acceleration has not been rescinded, on or prior to the Fundamental Change Purchase Date
(except in the case of an acceleration resulting from a default by the Company in the payment of
the Fundamental Change Purchase Price with respect to such Notes).




          (d) In connection with any purchase offer, the Company will:





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




     (ii) file a Schedule TO or any successor or similar schedule, if required under the
Exchange Act, and




     (iii) otherwise comply with all federal and state securities laws in connection with
any offer by the Company to purchase the Notes.



          Section 16.03. Withdrawal of Fundamental Change Purchase Notice. A Fundamental Change
Purchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the
Corporate Trust Office of the Paying Agent in accordance with this Section 16.03 at any time prior
to the close of business on the Business Day immediately preceding the Fundamental Change Purchase
Date, specifying:





     (i) the certificate number, if any, of the Note in respect of which such notice of
withdrawal is being submitted, or the appropriate Depositary information if the Note in
respect of which such notice of withdrawal is being submitted is represented by a Global
Note,




     (ii) the principal amount of the Note with respect to which such notice of withdrawal
is being submitted, and




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


provided, however, that if the Notes are not in certificated form, the notice must comply with
appropriate procedures of the Depositary.

          Section 16.04. Deposit of Fundamental Change Purchase Price.




          (a) The Company will deposit with the Trustee (or other Paying Agent appointed by the Company,
or if the Company is acting as its own Paying Agent, set aside, segregate and hold in trust as
provided in Section 5.04) on or prior to 11:00 a.m., New York City time, on the Fundamental Change
Purchase Date an amount of money sufficient to repurchase all of the Notes to be repurchased at the
appropriate Fundamental Change Purchase Price. Subject to receipt of funds and/or Notes by the
Trustee (or other Paying Agent appointed by the Company), payment for Notes surrendered for
repurchase (and not withdrawn prior to the Fundamental Change Expiration Time) will be made on the
later of (i) the Fundamental Change Purchase Date with respect to such Note (provided the holder
has satisfied the conditions in Section 16.02) and (ii) the time of book-entry transfer or the
delivery of such Note to the Trustee (or other Paying Agent appointed by the Company) by the holder
thereof in the manner required by Section 16.02 by mailing checks for the amount payable to the
holders of such Notes entitled thereto as they shall appear in the Note Register, provided,
however, that payments to the Depositary shall be made by wire transfer of immediately available
funds to the account of the Depositary or its nominee. The Trustee shall, promptly after such
payment and upon written demand by the Company, return to the Company any funds in excess of the
Fundamental Change Purchase Price.




          (b) If by 11:00 a.m. New York City time, on the Fundamental Change Purchase Date, the Trustee
(or other Paying Agent appointed by the Company) holds money sufficient to make payment on all the
Notes or portions thereof that are to be repurchased as a result of the corresponding Fundamental
Change, then (i) such Notes will cease to be outstanding, (ii) interest will cease to accrue on
such Notes, and (iii) all other rights of the holders of such Notes will terminate (other than the
right to receive the Fundamental Change Purchase Price, and previously accrued but unpaid interest,
including Additional Interest, if any, upon delivery of the Notes), whether or not book-entry
transfer of the Notes has been made or the Notes have been delivered to the Trustee or Paying
Agent.




          (c) Upon surrender of a Note that is to be repurchased in part pursuant to 16.02, the Company
shall execute and the Trustee shall authenticate and deliver to the holder a new Note in an
authorized denomination equal in principal amount to the unrepurchased portion of the Note
surrendered.

agent shall be deemed to be authentication and delivery of such Notes “by the Trustee” and a
certificate of authentication executed on behalf of the Trustee by an authenticating agent shall be
deemed to satisfy any requirement hereunder or in the Notes for the Trustee’s certificate of
authentication. Such authenticating agent shall at all times be a Person eligible to serve as

appointment to the Company and shall mail notice of such appointment to all Noteholders as the
names and addresses of such holders appear on the Note Register.




          The Company agrees to pay to the authenticating agent from time to time reasonable
compensation for its services although the Company may terminate the authenticating agent, if it
determines such agent’s fees to be unreasonable.




          The provisions of Section 8.02, Section 8.03, Section 8.04, Section 9.03 and this Section
17.11 shall be applicable to any authenticating agent.

thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of
authentication in the following form:







	 	 	 	 	 
	 	 	 
	
 	, 
	as Authenticating Agent, certifies that this is 	 
	one of the Notes described in the within-named
