    DEFINITIONS
AND INCORPORATION BY REFERENCE

    

    SECTION
1.1. Definitions.

    

    “Additional Notes” means
additional Notes (other than the Initial Notes), if any, issued under this
Indenture in accordance with Section 2.2 hereof, as part of the same series as
the Initial Notes.

    

    “Affiliate” means, with respect
to any specified Person, any other Person directly or indirectly controlling or
controlled by or under direct or indirect common control with such specified
Person. For the purposes of this definition, “control” when used with respect to
any specified Person means the power to direct the management and policies of
such Person, directly or indirectly, whether through the ownership of voting
securities, by contract or otherwise; and the terms “controlling” and
“controlled” have meanings correlative to the foregoing. No individual shall be
deemed to be controlled by or under common control with any specified Person
solely by virtue of his or her status as an employee or officer of such
specified Person or of any other Person controlled by or under common control
with such specified Person.

    

    “Applicable Conversion Price”
means, at any determination date, the Conversion Price then in effect (rounded

Indenture.

    

    “Applicable Conversion Rate”
means, as of any date of determination, an amount equal to $1,000 divided by the
then Applicable Conversion Price on such date. As of the date hereof and subject

nearest 1/10,000th of a share, for each $1,000 principal amount of the
Securities.

to have beneficial ownership of all securities that such “person” has the right
to acquire by conversion or exercise of other securities, whether such right is

in New York, New York are not required to be open.

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

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

    

    (c)     The
ownership of Notes shall be proved by the register for the Notes.

    

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

    

    (e)    
 If the Company shall solicit from the Holders any request, demand,
authorization, direction, notice, consent, waiver or other Act, the Company may,
at its option, by or pursuant to a Board Resolution, fix in advance a record
date for the determination of Holders entitled to give such request, demand,
authorization, direction, notice, consent, waiver or other Act, but the Company
shall have no obligation to do so. If such a record date is fixed, such request,
demand, authorization, direction, notice, consent, waiver or other Act may be
given before or after such record date, but only the Holders of record at the
close of business on such record date shall be deemed to be Holders for the
purposes of determining whether Holders of the requisite proportion of
Outstanding Notes have authorized or agreed or consented to such request,
demand, authorization, direction, notice, consent, waiver or other Act, and for
that purpose the Outstanding Notes shall be computed as of such record date;
provided that no such
authorization, agreement or consent by the Holders on such record date shall be
deemed effective unless it shall become effective pursuant to the provisions of
this Indenture not later than six months after the record date.

    SECTION
2.1. Form, Dating and
Terms.

    

    (a)    
The Notes shall be known and designated as 1.875% Convertible Senior Notes due
2028. Pursuant to the provisions of Article VI, the Notes shall be convertible
into Common Stock. Subject to the terms of this Indenture the Company may, at
its option, without consent from the Holders, issue Additional Notes from time
to time. For all purposes under the Indenture, the term “Notes” shall include the
Initial Notes and any such Additional Notes issued after the date of this
Indenture.

    

    
      
        
           

        

        
          11

          
            

          

        

        
           

        

      

    

     

    Notes may
be authenticated and delivered upon registration or transfer of, or in lieu of,
other Notes pursuant to Section 2.6, 2.7 or 10.8.

    

    The Notes
may have notations, legends or endorsements required by law, stock exchange rule
or usage, in addition to those set forth on Exhibit A. The Company and the
Trustee shall approve the forms of the Notes and any notation, endorsement or
legend on them. Each Note shall be dated the date of its authentication. The
terms of the Note set forth in Exhibit A are part of the terms of this Indenture
and, to the extent applicable, the Company and the Trustee, by their execution
and delivery of this Indenture, expressly agree to be bound by such
terms.

    

    The
principal of and interest on the Notes shall be payable at the office or agency
of the Company maintained for such purpose in the City of New York, or at such
other office or agency of the Company as may be maintained for such purpose
pursuant to Section 2.3. Payments in respect of a Certificated Note (including
principal and interest) shall be made in U.S. dollars at the office of the
Trustee. At the Company’s option, however, the Company may make such payments by
mailing a check to the registered address of each Holder thereof as such address
as shall appear on the Note Register or with respect to Notes represented by a
Global Note, by wire transfer of immediately available funds to the accounts
specified by the Depositary. If a payment date is a date other than a Business
Day, payment may be made at that place on the next succeeding day that is a
Business Day and no interest shall accrue for the intervening
period.

    

    The Notes
shall be initially issued in the form of one or more permanent Global Notes,
without interest coupons, substantially in the form of Exhibit A. Such Global
Notes shall be deposited on behalf of the purchasers of the Notes represented
thereby with the Notes Custodian for the Depositary for the accounts of
participants in the Depositary, duly executed by the Company and authenticated
by the Trustee as hereinafter provided. The aggregate principal amount of a
Global Note may from time to time be increased or decreased by adjustments made
on the records of the Notes Custodian, as hereinafter provided. Notwhithstanding
anything herein to the contrary, the Company may, at any time and in its sole
discretion, exchange any interest in the permanent Global Notes Benefically
Owned by an Affiliate of the Company for Certificated Notes and upon the written
request of the Company, togethor with such supporting documention as the Trustee
may request, the Trustee shall authenticate and deliver, to each such Beneficial
Owner identified by the Comany in exchange for its beneficial interest in such
Global Note, an equal aggregate principal amount of Certificated
Notes.

    

    (b)    
The Notes shall be issuable only in fully registered form, without coupons, and
only in denominations of $1,000 and $1,000 integral multiples
thereof.

    

    (c)     
Every Note that bears or is required under this Section 2.1(d) to bear the
legend set forth in this Section 2.1(d) (together with any Common Stock issued
upon conversion of the Notes and required to bear the legend set forth in
Section 2.1(e), collectively, the “Restricted Securities”) shall
be subject to the restrictions on transfer set forth in this Section 2.1(d)
(including the legend set forth below), unless such restrictions on transfer
shall be eliminated or otherwise waived by written consent of the Company, and
the Holder of each such Restricted Security, by such Holder’s acceptance
thereof, agrees to be bound by all such restrictions on transfer. As used in
Section 2.1(d) and Section 2.1(g), the term “transfer” encompasses any sale,
pledge, transfer or other disposition whatsoever of any Restricted
Security.

date (the “Resale Restriction
Termination Date”) the later of (1) the date that is 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 2.1(g), if
applicable) shall bear a legend in substantially the following form (unless such
Notes have been transferred pursuant to a registration statement that has become
or been declared effective under the Securities Act and that continues to be
effective at the time of such transfer, pursuant to the exemption from
registration provided by Rule 144 or any similar provision then in force or any
other exemption under the Securities Act, or unless otherwise agreed by the
Company in writing, with notice thereof to the Trustee):

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 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 Registrar in accordance with the
provisions of this Section 2.1, 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 2.1(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.

    

    (d) The
following book-entry provisions shall apply to Global Notes deposited with the
Notes Custodian:

    

    (1)   
 Each Global Note initially shall (x) be registered in the name of the
Depositary for such Global Note or the nominee of such Depositary and (y) be
delivered to the Notes Custodian.

    

    (2)     Except
as provided herein, members of, or participants in, the Depositary (“Agent Members”) shall have no
rights under this Indenture with respect to any Global Note held on their behalf
by the Depositary or by the Notes Custodian or under such Global Note, and the
Depositary may be treated by the Company, the Trustee, the Notes Custodian and
any agent of the Company or the Trustee as the absolute owner of such Global
Note for all purposes whatsoever. Notwithstanding the foregoing, nothing herein
shall prevent the Company, the Trustee or any agent of the Company or the
Trustee from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or impair, as between the Depositary
and its Agent Members, the operation of customary practices of the Depositary
governing the exercise of the rights of a Beneficial Owner of an interest in any
Global Note.

     

    
      
        
           

        

        
          14

          
            

          

        

        
           

        

      

    

    

    (3)     The
registered Holder of a Global Note may grant proxies and otherwise authorize any
Person, including Agent Members and Persons that may hold interests through
Agent Members, to take any action that a Holder is entitled to take under this
Indenture or the Notes.

    

    (4)      In
connection with the transfer of an entire Global Note to Beneficial Owners
pursuant to Section 2.1(f), such Global Note shall be deemed to be surrendered
to the Trustee for cancellation, and the Company shall execute, and the Trustee
shall authenticate and deliver, to each Beneficial Owner identified by the
Depositary in exchange for its beneficial interest in such Global Note, an equal
aggregate principal amount of Certificated Notes of authorized denominations.
The definitive securities shall be printed, lithographed or engraved or produced
by any combination of these methods, if required by any securities exchange on
which the Notes may be listed, on a steel engraved border or steel engraved
borders or may be produced in any other manner permitted by the rules of any
securities exchange on which the Notes may be listed, all as determined by the
officers executing such Notes, as evidenced by their execution of such
Notes.

    

    (5)     Any
Holder of a Global Note shall, by acceptance of such Global Note, agree that
transfers of beneficial interests in such Global Note may be effected only
through a book-entry system maintained by (a) the Holder of such Global Note (or
its agent) or (b) any Holder of a beneficial interest in such Global Note, and
that ownership of a beneficial interest in such Global Note shall be required to
be reflected in a book entry.

     

    (e)     Owners
of beneficial interests in Global Notes will not be entitled to receive
Certificated Notes; provided,
however, Certificated Notes shall be transferred to all Beneficial Owners
in exchange for their beneficial interests in a Global Note if the Depositary
notifies the Company that it is unwilling or unable to continue as depositary
for such Global Note or the Depositary ceases to be a clearing agency registered
under the Exchange Act, at a time when the Depositary is required to be so
registered in order to act as Depositary, and in each case a successor
depositary is not appointed by the Company within 90 days of such notice. The
Company shall promptly deliver a copy of any notice referred to in the foregoing
sentence to the Trustee.

transferred pursuant to a registration statement that has become or been
declared effective under the Securities Act and that continues to be effective

144).

Notwithstanding any provision of Section 2.1 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
2.1(i), (i) each reference in Section 2.1(d) 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, (ii) each reference
in Section 2.1(g) 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 2.1(i) will not be effective until such time as the Opinion of
Counsel and Officers’ Certificate have been received by the Trustee hereunder.
This Section 2.1(i) shall apply to successive amendments to Rule 144 (or any
successor rule) changing the holding period thereunder.

    

    SECTION
2.2. Execution and
Authentication. An Officer shall sign the Notes for the Company by manual
or facsimile signature. If an Officer whose signature is on a Note no longer
holds that office at the time the Trustee authenticates the Note, the Note shall
be valid nevertheless.

    

    A Note
shall not be valid until an authorized signatory of the Trustee manually
authenticates the Note. The signature of the Trustee on a Note shall be
conclusive evidence that such Note has been duly and validly authenticated and
issued under this Indenture.

    

    The
Trustee will, upon receipt of a written order of the Company signed by an
Officer of the Company (a “Company Order”), authenticate
Notes, including any Additional Notes, in an unlimited aggregate principal
amount, subject to the provisions of this Indenture and provided that no such
Additional Notes may be issued unless fungible with the Initial Notes for U.S.
tax purposes. Each Company Order will specify the amount of Notes to be
authenticated, the date on which the Notes are to be authenticated and, in the
case of Additional Notes, the issue price of such Notes. The Company may also
from time to time repurchase the Notes in open market purchases or negotiated
transactions without any notice to Holders. The Company may, to the extent
permitted by law, reissue or resell any such Notes or, at the option of the
Company, deliver them for cancellation to the Registrar.

     

    
      
        
           

        

        
          17

          
            

          

        

        
           

        

      

    

    

    The
Trustee may appoint an agent (the “Authenticating Agent”)
reasonably acceptable to the Company to authenticate the Notes. Unless limited
by the terms of such appointment, any such Authenticating Agent may authenticate
Notes whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such Authenticating
Agent.

    

    In case
the Company pursuant to Article IV shall be consolidated or merged with or into
any other Person or shall convey, transfer, lease or otherwise dispose of its
properties and assets substantially as an entirety to any Person, and the
successor Person resulting from such consolidation, or surviving such merger, or
into which the Company shall have been merged, or the Person that shall have
received a conveyance, transfer, lease or other disposition as aforesaid, shall
have executed an indenture supplemental hereto with the Trustee pursuant to
Article IV, any of the Notes authenticated or delivered prior to such
consolidation, merger, conveyance, transfer, lease or other disposition may,
from time to time, at the request of the successor Person, be exchanged for
other Notes executed in the name of the successor Person with such changes in
phraseology and form as may be appropriate, but otherwise in substance of like
tenor as the Notes surrendered for such exchange and of like principal amount;
and the Trustee, upon Company Order of the successor Person, shall authenticate
and deliver Notes as specified in such order for the purpose of such exchange.
If Notes shall at any time be authenticated and delivered in any new name of a
successor Person pursuant to this Section 2.2 in exchange or substitution for or
upon registration of transfer of any Notes, such successor Person, at the option
of the Holders but without expense to them, shall provide for the exchange of
all Notes at the time outstanding for Notes authenticated and delivered in such
new name.

    

    SECTION
2.3. Registrar,
Conversion Agent and Paying Agent. Deutsche Bank Trust Company Americas
shall initially serve as the Registrar, Conversion Agent and Paying Agent for
the Notes. The Registrar, the Conversion Agent and the Paying Agent shall
maintain an office or agency in the Borough of Manhattan, The City of New York.
If the Registrar, the Conversion Agent and the Paying Agent are not the same
party, the Registrar, the Conversion Agent and the Paying Agent shall each
maintain an office or agency in the Borough of Manhattan, The City of New York.
The Registrar shall keep a register of the Notes and of their transfer and
exchange (the “Note
Register”). The Company may have one or more co-registrars and one or
more additional conversion agents and paying agents. The term Paying Agent
includes any additional paying agents, the term Conversion Agent includes any
additional conversion agents and the term Registrar includes any co-registrar.
The Company may appoint and change any Paying Agent, Conversion Agent or
Registrar without prior notice to any Holder.

    

    The
Company shall enter into an appropriate agency agreement with any Registrar,
Conversion Agent or Paying Agent not a party to this Indenture, which upon
qualification of the Indenture under the TIA shall incorporate the terms of the
TIA. The agreement shall implement the provisions of this Indenture that relate
to such agent. The Company shall notify the Trustee and Deutsche Bank Trust
Company Americas, as long as they remain a Registrar, Conversion Agent or Paying
Agent, in writing of the name and address of each such agent. If the Company
fails to maintain a Registrar, Conversion Agent or Paying Agent, the Trustee
shall act as such and shall be entitled to appropriate compensation therefor
pursuant to Section 8.7. The Company or any of its domestically incorporated
Subsidiaries may act as Paying Agent, Conversion Agent or
Registrar.

     

    
      
        
           

        

        
          18

          
            

          

        

        
           

        

      

    

     

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

    

    SECTION
2.4. Paying Agent To
Hold Money and Securities in Trust. Except as otherwise provided herein,
on or prior to 11:00 a.m. (New York City time) on each due date of payment in
respect of any Note, the Company shall deposit with the Paying Agent a sum of
money (in immediately available funds) sufficient to make such payments when
due. The Company shall require each Paying Agent (other than the Trustee or
Deutsche Bank Trust Company Americas) to agree in writing that such Paying Agent
shall hold in trust for the benefit of Holders or the Trustee all money held by
such Paying Agent for the payment of principal of, interest on, and other
payments in respect of the Notes, and shall notify the Trustee in writing of any
default by the Company in making any such payment. If the Company or a
Subsidiary acts as Paying Agent, it shall segregate the money held by it as
Paying Agent and hold it as a separate trust fund for the benefit of the Holders
of the Notes. The Company at any time may require a Paying Agent (other than the
Trustee) to pay all money held by it to the Trustee and to account for any funds
disbursed by such Paying Agent. Upon complying with this Section 2.4, the Paying
Agent (if other than the Company or a Subsidiary) shall have no further
liability for the money delivered to the Trustee. Upon any bankruptcy,
reorganization or similar proceeding with respect to the Company, the Trustee
shall serve as Paying Agent for the Notes.

    

    SECTION
2.5. Holder
Lists. The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders and upon qualification of the Indenture under the TIA shall otherwise
comply with TIA Sec. 312(a). If the Trustee is not the Registrar or to the
extent otherwise required under the TIA upon qualification of the Indenture
thereunder, the Company, on its own behalf, shall furnish to the Trustee, in
writing at least seven Business Days before each Interest Payment Date and at
such other times as the Trustee may reasonably request in writing within 15
days, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of Holders and the Company shall otherwise
comply with TIA Sec. 312(a) upon qualification of the Indenture under the
TIA.

    

    SECTION
2.6. Transfer and
Exchange.

    

    (a) The
Registrar shall retain copies of all letters, notices and other written
communications received pursuant to Section 2.1 or this Section 2.6 until the
Notes have matured and been paid in full. The Company shall have the right to
inspect and make copies of all such letters, notices or other written
communications at any reasonable time during regular business hours upon the
giving of reasonable prior written notice to the Registrar.

     

    
      
        
           

        

        
          19

          
            

          

        

        
           

        

      

    

     

    (b)     The
following obligations with respect to transfers and exchanges of Notes shall
apply:

    

    (1)     To
permit registrations of transfers and exchanges, the Company shall, subject to
the other terms and conditions of this Article II, execute and the Trustee shall
upon receipt of a Company Order, authenticate Certificated Notes and Global
Notes at the Registrar’s request.

    

    (2)   
 No service charge shall be made to a Holder for any registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any transfer tax, assessments or similar governmental charge payable in
connection therewith (other than any such transfer taxes, assessments or similar
governmental charges payable upon exchange or transfer pursuant to Section
3.6).

    

    (3)     The
Registrar shall not be required to register the transfer of or exchange of any
Note (A) for a period beginning at the opening of business 15 days before any
selection of Notes for repurchase and ending at the close of business on the day
notice of such repurchase is deemed to have been given to all Holders of Notes
to be so repurchased or (B) selected for repurchase in whole or in
part.

    

    (4)      Except
as provided herein, prior to the due presentation for registration of transfer
of any Note, the Company, the Trustee, Paying Agent, the Conversion Agent or the
Registrar may deem and treat the Person in whose name a Note is registered as
the absolute owner of such Note for the purpose of receiving payment of
principal of and interest on such Note and for all other purposes whatsoever,
whether or not such Note is overdue, and none of the Company, the Trustee, the
Paying Agent, the Conversion Agent or the Registrar shall be affected by notice
to the contrary.

    

    (5)      All
Notes issued upon any transfer or exchange pursuant to the terms of this
Indenture shall evidence the same debt and shall be entitled to the same
benefits under this Indenture as the Notes surrendered upon such transfer or
exchange.

    

    (c)     If
any Holder of a beneficial interest in a Global Note proposes to exchange such
beneficial
interest for a Definitive Note or to transfer such beneficial interest to a
Person who takes
delivery thereof in the form of a Definitive Note, then, upon receipt by the
Registrar of a certificate
from such Holder in the form of Exhibit E hereto. The Trustee shall cause the
aggregate
principal amount of the applicable Global Note to be reduced accordingly and an
endorsement
shall be made on such Global Note by the Trustee or by the Depositary at the
direction
of the Trustee to reflect such reduction. The Company shall execute and the
Trustee shall
authenticate and deliver to the Person designated in the instructions a
Definitive Note in the appropriate
principal amount. Any Definitive Note issued in exchange for a beneficial
interest in a Global
Note pursuant to this Section 2.6(c) shall be registered in such name or names
and in such
authorized denomination or denominations as the Holder of such beneficial
interest shall instruct
the Registrar through instructions from the Depositary and the Agent Members The
Trustee
shall deliver such Definitive Notes to the Persons in whose names such Notes are
so registered.
Any Definitive Note issued in exchange for a beneficial interest in a Global
Note pursuant to this Section 2.6(c) shall bear the Legend and shall be subject
to all restrictions on transfer contained therein.

     

    
      
        
           

        

        
          20

          
            

          

        

        
           

        

      

    

     

    SECTION
2.7. Mutilated,
Destroyed, Lost or Stolen Notes. If a mutilated Note is surrendered to
the Registrar or if the Holder of a Note claims that the Note has been lost,
destroyed or wrongfully taken, subject to compliance with the provisions of the
next sentence of this Section 2.7, the Company shall issue and the Trustee, upon
Company Order, shall authenticate a replacement Note if the requirements of
Section 8-405 of the Uniform Commercial Code are met such that the Holder (a)
notifies the Company, the Registrar and the Trustee within a reasonable time
after such Holder has notice of such loss, destruction or wrongful taking and
the Registrar has not registered a transfer prior to receiving such
notification, (b) makes such request to the Company prior to the Company having
notice that the Note has been acquired by a protected purchaser as defined in
Section 8-303 of the Uniform Commercial Code (a “protected purchaser”), and (c)
satisfies any other reasonable requirements of the Company, the Registrar and
the Trustee. If required by the Registrar or the Company, such Holder shall
furnish an indemnity bond sufficient in the judgment of the Company and the
Registrar to protect the Company, the Trustee, the Paying Agent, the Conversion
Agent and the Registrar from any loss which any of them may suffer if a Note is
replaced. In the absence of notice to the Company, the Trustee, Paying Agent,
Conversion Agent or Registrar that such Note has been acquired by a protected
purchaser, the Company shall execute and upon Company Order the Trustee shall
authenticate and deliver, in exchange for any such mutilated Note or in lieu of
any such destroyed, lost or stolen Note, a new Note of like tenor and principal
amount, bearing a number not contemporaneously outstanding.

    

    In case
any such mutilated, destroyed, lost or stolen Note has become or is about to
become due and payable, the Company in its discretion, but subject to any
conversion rights, may, instead of issuing a new Note, pay such Note upon
satisfaction of the conditions set forth in the preceding
paragraph.

    

    Upon the
issuance of any new Note under this Section, the Company may require the payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including attorneys’ fees
and expenses and the fees and expenses of the Trustee) in connection
therewith.

    

    Every new
Note issued pursuant to this Section in lieu of any mutilated, destroyed, lost
or stolen Note shall constitute an original additional contractual obligation of
the Company and any other obligor upon the Notes, whether or not the mutilated,
destroyed, lost or stolen Note shall be at any time enforceable by anyone, and
shall be entitled to all benefits of this Indenture equally and proportionately
with any and all other Notes duly issued hereunder.

    

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

    

    SECTION
2.8. Cancellation. The
Company at any time may deliver Notes to the Registrar for cancellation. The
Trustee, the Conversion Agent and the Paying Agent shall forward to the
Registrar any Notes surrendered to them for payment, redemption, registration of
transfer, exchange or conversion. The Registrar and no one else shall cancel and
dispose of them in accordance with its customary procedures and upon written
request of the Company shall return to the Company all Notes surrendered for
registration of transfer, exchange, payment, purchase, conversion or
cancellation. All Notes so delivered to the Registrar shall be cancelled
promptly by the Registrar. The Company may not issue new Notes to replace Notes
it has paid or delivered to the Registrar for cancellation.

     

    
      
        
           

        

        
          21

          
            

          

        

        
           

        

      

    

     

    At such
time as all beneficial interests in a Global Note have either been exchanged for
Certificated Notes, transferred, paid, repurchased, converted or canceled, such
Global Note shall be returned by the Depositary or the Notes Custodian to the
Registrar for cancellation or retained and canceled by the Registrar. At any
time prior to such cancellation, if any beneficial interest in a Global Note is
exchanged for Certificated Notes, transferred in exchange for an interest in
another Global Note, paid, repurchased, converted or canceled, the principal
amount of Notes represented by such Global Note shall be reduced and an
adjustment shall be made on the Global Note and on the books and records of the
Registrar (if it is then the Notes Custodian for such Global Note) with respect
to such Global Note, by the Registrar or the Notes Custodian, to reflect such
reduction.

    

    SECTION
2.9. Payment of
Interest; Defaulted Interest. Interest on any Note that is payable, and
is punctually paid or duly provided for, on any Interest Payment Date will be at
a rate of 1.875% per annum, payable semi-annually in arrears on March 15 and
September 15 of each year, and shall be paid to the Person in whose name such
Note (or one or more predecessor Notes) is registered at the close of business
on the Regular Record Date for such interest at the office or agency of the
Company maintained for such purpose pursuant to Section 2.3 regardless of
whether or not such Holders convert their Notes.

    

    Any
interest on any Note that is payable, but is not paid when the same becomes due
and payable and such nonpayment continues for a period of 30 days shall
forthwith cease to be payable to the Holder on the Regular Record Date, and such
defaulted interest and (to the extent lawful) interest on such defaulted
interest at the rate borne by the Notes (such defaulted interest and interest
thereon herein collectively called “Defaulted Interest”) shall be
paid by the Company, at its election, as provided below:

    

    The
Company may elect to make payment of any Defaulted Interest to the Persons in
whose names the Notes (or their respective predecessor Notes) are registered at
the close of business on a Special Record Date (as defined below) for the
payment of such Defaulted Interest, which shall be fixed in the following
manner. The Company shall notify the Trustee and the Paying Agent in writing of
the amount of Defaulted Interest proposed to be paid on each Note and the date
(not less than 30 days after such notice) of the proposed payment (the “Special Interest Payment
Date”), and the Company shall make arrangements reasonably satisfactory
to the Trustee and the Paying Agent to deposit with the Paying Agent an amount
of money equal to the aggregate amount proposed to be paid in respect of such
Defaulted Interest on or prior to the date of the proposed payment, such money
when deposited to be held in trust for the benefit of the Persons entitled to
such Defaulted Interest as in this clause provided. Thereupon the Trustee shall
fix a record date (the “Special
Record Date”) for the payment of such Defaulted Interest which shall be
not more than 15 days and not less than 10 days prior to the Special Interest
Payment Date and not less than 10 days after the receipt by the Trustee of the
notice of the proposed payment. The Trustee shall promptly notify the Company
and the Paying Agent of such Special Record Date, and in the name and at the
expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date and Special Interest Payment Date
therefor, which notice shall be prepared by the Company and shall be in a form
reasonably acceptable to the Trustee, to be given in the manner provided for in
Section 11.2, not less than 10 days prior to such Special Record Date. Notice of
the proposed payment of such Defaulted Interest and the Special Record Date and
Special Interest Payment Date therefor having been so given, such Defaulted
Interest shall be paid on the Special Interest Payment Date to the Persons in
whose names the Notes are registered at the close of business on such Special
Record Date.

    

    
      
        
           

        

        
          22

          
            

          

        

        
           

        

      

    

    

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

    

    SECTION
2.10. Computation of
Interest. Interest on the Notes shall be computed on the basis of a
360-day year comprised of twelve 30-day months.

    

    SECTION
2.11. CUSIP
Numbers. The Company in issuing the Notes and Common Stock upon
conversion of the Notes may use CUSIP numbers (if then generally in use) and, if
so, the Trustee shall use the CUSIP numbers in notices of redemption as a
convenience to Holders; provided, however, that neither the
Company nor the Trustee shall have responsibility for any defect in the CUSIP
number that appears on any Note, check, advice of payment or redemption notice
and any such notice may state that no representation is made to the correctness
of such numbers either as printed on the Notes or as contained in any notice of
a redemption and that reliance may be placed only on the other identification
numbers printed on the Notes, and any such redemption shall not be affected by
any defect in or omission of such numbers. The Company shall promptly notify the
Trustee in writing of any change in the CUSIP numbers.

    

    SECTION
2.12. Calculations in
Respect of the Notes. The Company shall be responsible for making all
calculations called for under the Notes. These calculations include, but are not
limited to, determinations of the Closing Sale Price of the Common Stock, any
accrued interest (including Liquidated Damages and Additional Interest, if any)
payable on the Notes and the Applicable Conversion Price of the Notes and
adjustments to the Applicable Conversion Price. The Company shall make these
calculations in good faith and, absent manifest error, such calculations will be
final and binding on Holders of the Notes. The Company shall provide to the
Trustee and the Conversion Agent a schedule of its calculations, and the Trustee
and the Conversion Agent, subject to Sections 8.1 and 8.2, shall be entitled to
rely upon the accuracy of such calculations without independent verification.
The Trustee shall forward the Company’s calculations to any Holder of the Notes
upon the request of such Holder.

    

    SECTION
2.13. Liquidated
Damages Under Registration Rights Agreement. Any Liquidated Damages
payable pursuant to the terms of the Registration Rights Agreement are deemed to
be interest for purposes of this Indenture.

     

    
      
        
           

        

        
          23

          
            

          

        

        
           

        

      

    

     

    SECTION
2.14. Ranking.
The Notes will be senior, unsecured obligations of the Company and will rank
equal in right of payment to all of the Company’s existing senior unsecured debt
and senior to all of the Company’s future subordinated
indebtedness.

III

    

    COVENANTS

    

    SECTION
3.1. Payment of
Notes. The Company will pay or cause to be paid the principal of and
interest, if any, on the Notes on the dates and in the manner provided in the
Notes. Principal and interest, if any, will be considered paid on the date due
if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as
of 11:00 a.m. New York City time on the due date money deposited by the Company
in immediately available funds and designated for and sufficient to pay all
principal and interest then due.

    

    The
Company will pay interest on overdue principal at the then applicable interest
rate on the Notes to the extent lawful; it will pay interest on overdue
installments of interest (without regard to any applicable grace period) at the
same rate to the extent lawful.

    

    SECTION
3.2. Maintenance of
Office or Agency. The Company will maintain in the Borough of Manhattan,
the City of New York, an office or agency (which may be an office of the Trustee
or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be
surrendered for registration of transfer or for exchange and where notices and
demands to or upon the Company in respect of the Notes and this Indenture may be
served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company fails to maintain any such required office or agency or fails
to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of
Deutsche Bank Trust Company Americas.

    

    The
Company may also from time to time designate 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, however, that no
such designation or rescission will in any manner relieve the Company of its
obligation to maintain an office or agency in the Borough of Manhattan, the City
of New York, for such purposes. The Company 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
Company hereby designates the office of Deutsche Bank Trust Company Americas as
one such office or agency of the Company.

of the signatories of which shall be the chief executive officer, chief
financial officer or chief accounting officer of the Company, stating that in
the course of the performance by the signer of his or her duties as an Officer
of the Company, he or she would normally have knowledge of any Default and
whether or not such signer knows of any Default that occurred during such
period. If such signer does have knowledge of a Default, the certificate shall
describe the Default, its status and what action the Company is taking or
proposes to take with respect thereto. The Company also shall comply with
Section 314(a)(4) of the TIA upon qualification of the Indenture under the
TIA.

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

    

    SECTION
3.4. Reservation of
Common Stock. The Company shall at all times reserve and keep available,
free from preemptive rights, out of its authorized but unissued Common Stock or
shares held in treasury by the Company, for the purpose of effecting the
conversion of Notes, the full number of shares of Common Stock then issuable
upon the conversion of all outstanding Notes.

    

    SECTION
3.5. Issuance of
Shares. All shares of Common Stock delivered upon conversion of the Notes
shall be newly issued shares or shares held in treasury by the Company, shall
have been duly authorized and validly issued and shall be fully paid and
nonassessable, and shall be free from preemptive rights and free of any Lien or
adverse claim.

    

    SECTION
3.6. Transfer
Taxes. If a Holder converts Notes for shares of Common Stock, the Company
will pay any and all documentary, stamp or similar issue or transfer tax due on
the issue of shares of Common Stock upon the conversion. The Company shall not,
however, be required to pay any tax or duty that may be payable in respect of
any transfer involved in the issue and delivery of shares of Common Stock in a
name other than that of the Holder of the Note or Notes to be converted, and no
such issue or delivery shall be made unless and until the Person requesting such
issue has paid to the Company the amount of any such tax or duty, or has
established to the satisfaction of the Company that such tax or duty has been
paid.

    

    SECTION
3.7. SEC and Other
Reports. The Company shall file with the Trustee and the SEC, and
transmit to Holders, such information, documents and other reports and such
summaries thereof, as may be required pursuant to the TIA at the times and in
the manner provided pursuant to the TIA; provided that any such information,
documents or reports required to be filed with the SEC pursuant to Section 13 or
15(d) of the Exchange Act shall, unless such information, documents or reports
are available on the SEC’s EDGAR filing system (or any successor thereto), be
filed with the Trustee within 30 days after the same is so required to be filed
with the SEC. The Company also shall comply with the other provisions of TIA
Section 314(a) upon qualification of the Indenture under the TIA. Delivery of
such reports, information and documents to the Trustee is for informational
purposes only and the Trustee’s receipt of such shall not constitute
constructive notice of any information contained therein or determinable from
information contained therein, including the Company’s compliance with any of
its covenants hereunder (as to which the Trustee is entitled to rely
conclusively on Officers’ Certificates). The requirements under this Section 3.7
shall be deemed satisfied upon the filings of such reports, information and
documents with the SEC.

4.1. Merger,
Consolidation or Sale of Assets. The Company shall not, directly or
indirectly, consolidate or merge with or into any other Person in a transaction
in which the Company is not the surviving corporation or convey, transfer or
lease the properties and assets of the Company substantially as an entirety to
any successor Person, unless:

    

    (a) the
successor Person, if any, is:

    

    (1)    a
corporation organized and existing under the laws of the United States, any
state of the United States, or the District of Columbia;

    

    (2)    such
Person assumes the Company’s obligations on the Notes and under this Indenture
pursuant to agreements reasonably satisfactory in form and substance to the
Trustee;

    

    (3)    
immediately after giving effect to the transaction, no Default or Event of
Default will have occurred and be continuing; and

    

    (4)     the
Company shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that such consolidation, merger, conveyance,
transfer or lease and, if a supplemental indenture is required in connection
with such transaction, such supplemental indenture, comply with this Article IV
and that all conditions precedent herein provided for relating to such
transaction have been satisfied.

    

    This
Section 4.1 will not apply to a merger of the Company with an Affiliate solely
for the purpose of reincorporating the Company in another
jurisdiction.

    

    SECTION
4.2. Successor
Corporation Substituted. Upon any consolidation or merger, or any sale,
assignment, transfer, lease, conveyance or other disposition of all or
substantially all of the properties or assets of the Company in a transaction
that is subject to, and that complies with the provisions of, Section 4.1
hereof, the successor Person formed by such consolidation with or into which the
Company is merged or to which such sale, assignment, transfer, lease, conveyance
or other disposition is made shall succeed to, and be substituted for (so that
from and after the date of such consolidation, merger, sale, assignment,
transfer, lease, conveyance or other disposition, the provisions of this
Indenture referring to the “Company” shall refer instead
to the successor Person and not to the Company), and may exercise every right
and power of the Company under this Indenture with the same effect as if such
successor Person had been named as the Company herein; provided, however, that the
predecessor Company shall not be relieved from the obligation to pay the
principal of and interest on the Notes except in the case of a transaction that
is subject to, and that complies with the provisions of, Section 4.1
hereof.

    REDEMPTION
OF NOTES

    

    SECTION
5.1. Company’s Right
to Redeem; Notices to Trustee. The Notes will not be subject to
redemption prior to March 22, 2013, except as otherwise set forth in this
Section 5.1. On or after March 22, 2013, the Company shall have the right to
redeem the Notes in whole or in part, for a cash Redemption Price equal to 100%
of the principal amount of the Notes to be redeemed, plus any accrued and unpaid
interest (including Liquidated Damages and Additional Interest, if any) thereon
up to, but not including, the Redemption Date (the “Redemption Price”). If the
Redemption Date is after a Regular Record Date and on or before the Interest
Payment Date to which it relates, the Company will pay any accrued and unpaid
interest (including Liquidated Damages and Additional Interest, if any) to a
Holder on such regular Record Date; otherwise, interest payable upon redemption
will be paid to the Holder to whom principal is payable in connection with such
redemption. If the Company calls any or all of the Notes for redemption, Holders
may convert their Securities that have been so called for redemption at any time
prior to 5:00 p.m. (New York City Time) one Business Day prior to the Redemption
Date, even if such Notes are not otherwise convertible at such time, after which
such Holders’ right to convert will expire unless the Company defaults in the
payment of a Redemption Price.

    

    The
Company shall give each notice to the Trustee provided for in this Section 5.1
at least 60 days before the Redemption Date unless the Trustee consents to a
shorter period. Such notice shall be accompanied by an Officers’ Certificate and
an Opinion of Counsel from the Company to the effect that such redemption will
comply with the conditions herein.

    

    SECTION
5.2. Selection of
Notes To Be Redeemed. If fewer than all outstanding Notes are to be
redeemed, the Trustee shall select the Notes to be redeemed by lot, on a pro
rata basis or by another method that the Trustee considers fair and appropriate,
including any method required by DTC or any successor Depositary. The Trustee
shall make the selection from outstanding Notes not previously called for
redemption. The Trustee may select for redemption portions of the principal
amount of Notes that have denominations larger than $1,000. Notes and portions
of Notes the Trustee selects shall be in principal amounts of $1,000 or
multiples thereof. Provisions of this Indenture that apply to Notes called for
redemption also apply to portions of Notes called for redemption. The Trustee
shall notify the Company promptly of the Notes or portions of Notes to be
redeemed.

    

    If the
Trustee selects a portion of a Holder’s Notes for partial redemption and such
Holder converts a portion of the same Notes, the converted portion will be
deemed first to be from the portion selected for redemption.

    

    SECTION
5.3. Notice of
Redemption. At least 30 days but not more than 60 days before a
Redemption Date, the Company or the Trustee shall mail a notice of redemption by
first-class mail, postage prepaid, to each Holder of Notes to be
redeemed.

    

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

    

    (a)    
the Redemption Date;

    

    
      
        
           

        

        
          27

          
            

          

        

        
           

        

      

    

    

    (b)     the
Redemption Price;

    

    (c)    
the Applicable Conversion Price;

    

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

    

    (e)     that
Notes called for redemption may be converted at any time before the close of
business on the Business Day immediately preceding the Redemption
Date;

    

    (f)      that
Holders who want to convert their Notes must satisfy all the requirements set
forth herein and in the Notes;

    

    (g)     that
Notes called for redemption must be surrendered to the Paying Agent to collect
the Redemption Price;

    

    (h)    
if fewer than all of the outstanding Notes are to be redeemed, the certificate
numbers, if any, and principal amounts of the particular Notes to be
redeemed;

    

    (i)     
that, unless the Company defaults in making payment of such Redemption Price,
interest, if any (including Liquidated Damages and Additional Interest, if any),
on Notes called for redemption will cease to accrue on and after the Redemption
Date; and

    

    (j)     
the CUSIP number of the Notes.

    

    At the
Company’s request, the Trustee shall give the notice of redemption in the
Company’s name and at the Company’s expense, provided that the Company
makes such request at least three Business Days prior to the date by which such
notice of redemption must be given to Holders in accordance with this Section
5.1, provided further
that, in all cases, the text of such notice of redemption shall be
prepared by the Company.

    

    SECTION
5.4. Effect of Notice
of Redemption. Once notice of redemption is given, Notes called for
redemption become due and payable on the Redemption Date and at the Redemption
Price stated in the notice of redemption except for Notes which are converted in
accordance with the terms of this Indenture. Upon surrender to the Paying Agent,
such Notes shall be paid at the Redemption Price stated in the notice of
redemption.

    

    SECTION
5.5. Deposit of
Redemption Price. Prior to 10:00 a.m. (New York City time), on the
Redemption Date, the Company shall deposit with the Paying Agent (or if the
Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust)
money sufficient to pay the Redemption Price of all Notes to be redeemed on that
date other than Notes or portions of Notes called for redemption which have been
delivered by the Company to the Trustee for cancellation or which have been
converted. The Paying Agent shall as promptly as practicable return to the
Company any money not required for that purpose because of conversion of Notes
pursuant to Article VI. If such money is then held by the Company in trust and
is not required for such purpose it shall be discharged from such
trust.

    

    SECTION
5.6. Notes Redeemed in
Part.

    

    
      
        
           

        

        
          28

          
            

          

        

        
           

        

      

    

    

    (a)  
In the event of any redemption in part, the Company will not be required to
register the transfer of or exchange of any Notes, so selected for redemption,
in whole or in part, except the unredeemed portion of any Notes being redeemed
in part.

    

    (b)  
Upon surrender of a Note that is redeemed in part, 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 unredeemed portion of
the Note surrendered, or in the case of a Global Note, the Company shall
instruct the Registrar to decrease such Global Note by the principal amount of
the redeemed portion of the Note surrendered.

    

    SECTION
5.7. Purchase of Notes
by the Company at Option of the Holder.

    

    (a) General. Notes shall be
purchased by the Company at the option of the Holder on March 15, 2013, March
15, 2018 and March 15, 2023 or the next Business Day following such date to the
extent any such date is not a Business Day (each, a “Purchase Date”). Notes and
portions of Notes purchased by the Company pursuant to this Section 5.7 shall be
in principal amounts of $1,000 or multiples thereof. All Notes purchased by the
Company will be paid for in U.S. legal tender (“Cash” or “cash”) equal to 100% of the
principal amount to be purchased plus any accrued and unpaid interest (including
Liquidated Damages and Additional Interest, if any), thereon up to, but not
including, such Purchase Date (the “Purchase Price”).

    

    No Notes
may be purchased by the Company at the option of Holders if there has occurred
and is continuing an Event of Default with respect to the Notes, other than an
Event of Default that is cured by payment of the Purchase Price of the Notes.
The Company shall be required to purchase any outstanding Notes
upon:

    

    (1)
delivery to the Paying Agent and the Company by the Holder of a written notice
(or in the case of Global Notes, a notice delivered electronically or by other
means in accordance with the Depositary’s customary procedures) of purchase (a
“Purchase Notice”)
during the period beginning at any time from the opening of business on the date
that is 20 Business Days prior to the relevant Purchase Date until the close of
business on the second Business Day prior to such Purchase Date. The Purchase
Notice electing the Company to purchase the Notes must state:

    

    (i) if
Certificated Notes have been issued, the certificate number of the Notes, or if
not Certificated Notes, such Purchase Notice must comply with appropriate DTC
procedures;

    

    (ii) the
portion of the principal amount to be purchased, in multiples of $1,000;
and

    

    (iii) the
Notes shall be purchased by the Company pursuant to the applicable terms of the
Notes and this Indenture.

    

    Simultaneously
with providing such Purchase Notice, the Company shall publish a notice
containing the information contemplated by this Section 5.7(a)(1) 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.

     

    
      
        
           

        

        
          29

          
            

          

        

        
           

        

      

    

     

    The
Company shall purchase from the Holder thereof, pursuant to this Section 5.7, a
portion of a Note, if the principal amount of such portion is $1,000 or an
integral multiple of $1,000. Provisions of this Indenture that apply to the
purchase of all of a Note also apply to the purchase of such portion of such
Note.

    

    A Holder
shall either effect book-entry transfer or deliver the Notes, together with
necessary endorsements, to the office of the Paying Agent after delivery of the
Purchase Notice to receive payment of the Purchase Price. A Holder shall receive
payment promptly following the later of the Purchase Date or the time of
book-entry transfer or the delivery of the Notes. If the Paying Agent holds
money sufficient to pay the Purchase Price of the Note on such Business Day
following the Purchase Date, then the Notes will cease to be outstanding and
interest (including Liquidated Damages and Additional Interest, if any) on such
Note will cease to accrue (whether not book-entry transfer of the Note is made
or whether the Note is delivered to the Paying Agent), and all other rights of
the Holder shall terminate (other than the right to receive the Purchase Price
and previously accrued and unpaid interest and additional interest upon delivery
on transfer of the Notes).

    

    If a
Holder of Notes has given the Purchase Notice, the Holder may only convert such
Notes if the Holder withdraws the Purchase Notice delivered by such Holder in
accordance with the terms of this Indenture and the Holder is otherwise entitled
to convert the Notes.

    

    Notwithstanding
anything herein to the contrary, any Holder delivering to the Paying Agent the
Purchase Notice contemplated by this Section 5.7 shall have the right to
withdraw any such Purchase Notice in whole or in part by a written notice of
withdrawal to the Paying Agent in accordance with Section 5.9 prior to the close
of business on the Business Day prior to the Purchase Date. If the Purchase
Notice is given and withdrawn during such period, the Company will not be
obligated to purchase the related Notes. The Paying Agent shall promptly notify
the Company of the receipt by it of any written notice of withdrawal of a
Purchase Notice. The Company shall be responsible for making all determinations
with respect to the adequacy of such Purchase Notice electing to require the
Company to purchase the Notes and all notices withdrawing such elections and any
such determination shall be binding on the applicable Holder. The Company shall
comply with the provisions of Rule 13e-4, to the extent applicable, and any
other rules under the Exchange Act that may be applicable.

    

    (b) Company Notice. On or before
the 20th
Business Day prior to each Purchase Date (the “Company Notice Date”), the
Company shall mail a notice to the Trustee, the Paying Agent, all Holders of the
Notes and to beneficial owners as required by applicable law, setting forth
information specified in this Section 5.7(b) (the “Company Notice”).

    

    Each
Company Notice shall include a form of Purchase Notice to be completed by a
Holder and shall state:

    

    (1)       the
last date on which a Holder may exercise the purchase right;

    

    (2)       the
Purchase Price;

    

    
      
        
           

        

        
          30

          
            

          

        

        
           

        

      

    

     

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

    

    (4)      the
Applicable Conversion Price estimated as of a recent date, and to the extent
known at the time of such Company Notice, the amount of accrued but unpaid
interest that will be payable with respect to each $1,000 principal amount of
the Notes on Purchase Date;

    

    (5)      that
Notes as to which a Purchase Notice has been given may be converted if they are
otherwise convertible only in accordance with Article VI hereof and the
applicable provisions of the Notes if the applicable Purchase Notice has been
withdrawn in accordance with the terms of this Indenture;

    

    (6)      that
Notes must be surrendered to the Paying Agent to collect payment;

    

    (7)      that
the Purchase Price for any Note as to which a Purchase Notice has been given and
not withdrawn will be paid on the Business Day following the later of the
Purchase Date or the time of book-entry transfer or the delivery of the Notes
and the Holder’s satisfaction of all applicable conditions;

    

    (8)      the
procedures the Holder must follow to exercise its purchase rights under this
Section 5.7 and a brief description of such rights;

    

    (9)      
briefly, the conversion rights, if any, of the Notes;

    

    (10)     the
procedures for withdrawing a Purchase Notice;

    

    (11)     that,
unless the Company defaults in making payment on Notes for which a Purchase
Notice has been submitted, interest, if any (including Liquidated Damages,
Additional Interest and Additional Amounts, if any), on such Notes will cease to
accrue on and after the Purchase Date; and

    

    (12)     the
CUSIP number of the Notes.

    

    At the
Company’s request, the Trustee shall give such Company Notice in the Company’s
name and at the Company’s expense; provided that the Company
makes such request at least three Business Days prior to the date by which such
Company Notice must be given to Holders in accordance with this Section 5.7;
provided further that,
in all cases, the text of such Company Notice shall be prepared by the
Company.

    

    (c) Procedure upon Purchase. The
Company shall deposit cash in respect of cash repurchases under this Section 5.7
at the time and in the manner as provided in Section 5.10, sufficient to pay the
aggregate Purchase Price of all Notes to be purchased pursuant to this Section
5.7.

(the “Fundamental Change
Purchase Date”) at a purchase price equal to 100% of the principal amount
of the Notes, together with any accrued and unpaid interest (including
Liquidated Damages and Additional Interest, if any) to, but excluding, the
Fundamental Change Purchase Date (the “Fundamental Change Purchase
Price”), payable in Cash, subject to satisfaction by or on behalf of any
Holder of the requirements set forth in Section 5.8(c). Notes and portions of
Notes purchased by the Company pursuant to this Section 5.8 shall be in
principal amounts of $1,000 or multiples thereof.

    

    A “Fundamental Change” shall mean
the occurrence of a Change in Control or a Termination of Trading.

    

    A “Change in Control” shall be
deemed to have occurred if any of the following occurs after the date of this
Indenture:

    

    (1)     any
“person” or “group” other than any of the Permitted Holders is or becomes the
direct or indirect Beneficial Owner of shares of Voting Stock representing 50%
or more of the total voting power of all outstanding classes of the Company’s
Voting Stock or has the power, directly or indirectly, to elect a majority of
the members of the Board of Directors;

    

    (2)     the

Company sells, assigns, conveys, transfers, leases or otherwise disposes of all

    (3)     the
Permitted Holders, considered as a group, are or become the beneficial owners,
directly or indirectly, of more than 60% of the total voting power of all
outstanding classes of the Company’s Voting Stock provided, however, that the
Permitted Holders’ ownership may exceed 60% if such excess is solely as a result
of acquisitions from us after the date of this Indenture of newly issued shares
of the Company’s Voting Stock other than as a result of the retirement of shares
of the Company’s Voting Stock outstanding as of the date of this
Indenture;

    

    (4)     a
majority of the members of the Board of Directors are not Continuing Directors;
or

    

    (5)     the
holders of the Company’s Capital Stock approve any plan or proposal for the
liquidation or dissolution of the Company, whether or not in compliance with the
terms hereof.

    
      
         

        Notwithstanding
anything to the contrary set forth in this Section 5.8, Holders will not have
the right to require the Company to purchase any Notes as a result of any
transaction described in clause (i) or (ii) of the definition of “Change in
Control” above, and the Company will not be required to deliver a Fundamental
Change Notice, as a result of any transaction constituting a Change in Control

shares of the Company’s Voting Stock immediately prior to such transaction
“beneficially own,” directly or indirectly, the shares of the Company’s Voting
Stock representing at least a majority of the total voting power of all
outstanding classes of Voting Stock of the surviving or transferee person, or if
at least 90% of the consideration paid for the Common Stock, excluding Cash
payments for fractional shares and Cash payments made pursuant to dissenters’
appraisal rights, consists of shares of common stock, depositary receipts or
other certificates representing common equity interests traded on a U.S.
national securities exchange, or will be so traded immediately following the
merger or consolidation, and, as a result of the merger or consolidation, the
Notes become convertible into such shares of such common stock, depositary
receipts or other certificates representing common equity
interests.

“group” (as such terms are defined above) or other Person with respect to which
the Change in Control determination is being made, all Unissued Shares deemed to
be held by all other Persons, (iii) Permitted Holders (the “Permitted Holders”) means
Mining and Metallurgical Company Norilsk Nickel and its existing and future

Simultaneously with providing such notice, the Company will issue a press
release and publish the information on its website. The Fundamental Change

Business Day following the later of the Fundamental Change Purchase Date and the
Holder’s satisfaction of all applicable conditions;

      

      (9)   briefly,

and

      

      (13)   the
CUSIP number of the Notes.

      

      At the
Company’s request, the Trustee shall give such Fundamental Change Notice in the
Company’s name and at the Company’s expense, provided that the Company
makes such request at least three Business Days prior to the date by which such
Fundamental Change Notice must be given to Holders in accordance with this
Section 5.8; provided further
that, in all cases, the text of such Fundamental Change Notice shall be
prepared by the Company.

      

      (c) A
Holder may exercise its rights specified in subsection (b) of this Section 5.8
upon delivery of a written notice which may be delivered by letter, overnight
courier, hand delivery, facsimile transmission or in any other manner reasonably
acceptable to the Paying Agent and, in the case of Global Notes, may be

customary procedures of the exercise of such rights (a “Fundamental Change Purchase
Notice”) to any Paying Agent during the period between the Fundamental
Change Purchase Notice and 5:00 p.m. (New York City time) on the Business Day
prior to the Fundamental Change Purchase Date, specifying:

      

      (1)   if
the Notes are Certificated Notes, the certificate number of the Note which the
Holder will deliver to be purchased; if the Notes are not Certificated Notes,
all information required to comply with all DTC procedures;

      (2)   the
principal amount of the Note, or portion thereof, which the Holder will deliver

and

      

      (3)   that
such Note shall be purchased pursuant to the terms and conditions specified in
the applicable provisions of such Note and this Indenture.

      

      The
delivery of such Notes to the Paying Agent with the Fundamental Change Purchase
Notice (together with all necessary endorsements and compliance by the Holder
with all DTC procedures) at the offices of the Paying Agent shall be a condition
to the receipt by the Holder of the Fundamental Change Purchase Price
therefor.

      

      The
Company shall purchase from the Holder thereof, pursuant to this Section 5.8, a
portion of a Note if the principal amount of such portion is $1,000 or an
integral multiple of $1,000. Provisions of this Indenture that apply to the
purchase of all of a Note also apply to the purchase of such portion of such
Note.

      

      Any
purchase by the Company contemplated pursuant to the provisions of this Section
5.8 shall be consummated by the delivery of the consideration to be received by
the Holder on the Business Day following the later of the Fundamental Change
Purchase Date or the satisfaction of the foregoing conditions to such purchase
to be fulfilled by the Holder hereunder. If the Paying Agent holds money
sufficient to pay the Fundamental Change Purchase Price of the Notes which
Holders have elected to require the Company to purchase on such Business Day in
accordance with the terms of this Indenture, then, from and including the
Fundamental Change Purchase Date, those Notes will cease to be outstanding and
interest (including Liquidated Damages, Additional Interest and Additional
Amounts, if any) on the Notes will cease to accrue and all other rights of the
Holders shall terminate, other than the right to receive the Fundamental Change
Purchase Price upon satisfaction of the foregoing conditions.

      

      (d) Procedure upon Purchase. The
Company shall deposit cash, at the time and in the manner as provided in Section
5.10, sufficient to pay the aggregate Fundamental Change Purchase Price of all
Notes to be purchased pursuant to this Section 5.8.

      

      SECTION
5.9. Effect of
Purchase Notice or Fundamental Change Purchase Notice. Upon receipt by
the Paying Agent of the Purchase Notice or Fundamental Change Purchase Notice
specified in Section 5.7(a) or Section 5.8(c), as applicable, the Holder of the
Note in respect of which such Purchase Notice or Fundamental Change Purchase
Notice, as the case may be, was given, shall (unless such Purchase Notice or
Fundamental Change Purchase Notice, as the case may be, is withdrawn as
specified in the following paragraph) thereafter be entitled to receive solely
the Purchase Price or Fundamental Change Purchase Price, as the case may be,
with respect to such Note. Such Purchase Price or Fundamental Change Purchase
Price shall be paid to such Holder, subject to receipt of funds by the Paying
Agent, promptly following the later of (i) the Business Day following the

respect to such Note (provided the conditions in Section 5.7(a) or Section
5.8(c), as applicable, have been satisfied) and (ii) the time of delivery of
such Note to the Paying Agent by the Holder thereof in the manner required by
Section 5.7(a) or Section 5.8(c), as applicable. Notes in respect of which a
Purchase Notice or Fundamental Change Purchase Notice has been given by the
Holder thereof may not be converted pursuant to Article VI hereof on or after
the date of the delivery of such Purchase Notice or Fundamental Change Purchase
Notice unless such Purchase Notice or Fundamental Change Purchase Notice has
first been validly withdrawn as specified in the following
paragraph.

      
        
           

        

        
          35

          
            

          

        

        
           

        

      

       

      A
Purchase Notice or Fundamental Change Purchase Notice may be withdrawn by means
of a written notice of withdrawal delivered to the office of the Paying Agent in
accordance with the Purchase Notice or Fundamental Change Purchase Notice, as
the case may be, at any time prior to 5:00 p.m. (New York City time) on the
Business Day prior to the Purchase Date or the Fundamental Change Purchase Date,
as the case may be, specifying:

      

      (a)   if
Certificated Notes have been issued, the certificate number of the withdrawn
Note, if the Notes are not Certificated Notes, such notice shall comply with the
appropriate DTC procedures;

      

      (b)   the
principal amount of the withdrawn Note; and

      

      (c)   the
principal amount, if any, of such Note which remains subject to the original
Purchase Notice or Fundamental Change Purchase Notice, as the case may be, and
which has been or will be delivered for purchase by the Company.

      

      SECTION
5.10. Deposit of
Purchase Price or Fundamental Change Purchase Price. Prior to 11:00 a.m.
(New York City time) on the Business Day following the later of the Purchase
Date or the Fundamental Change Purchase Date, as the case may be, and the
Holder’s satisfaction of all applicable conditions specified in Section 5.7(a)
or Section 5.8(c), as applicable, the Company shall deposit with the Trustee or
with the Paying Agent (or, if the Company or a Subsidiary or an Affiliate of
either of them is acting as the Paying Agent, shall segregate and hold in trust
as provided in Section 2.4) an amount of cash (in immediately available funds if
deposited on such Business Day), sufficient to pay the aggregate Purchase Price
or Fundamental Change Purchase Price, as the case may be, of all the Notes or
portions thereof which are to be purchased in respect of such Purchase Date or
Fundamental Change Purchase Date, as the case may be.

      

      SECTION
5.11. Securities
Purchased in Part. Any Certificated Note which is to be purchased only in
part shall be surrendered at the office of the Paying Agent (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument
of transfer in form satisfactory to the Company and the Trustee, duly executed
by the Holder thereof or such Holder’s attorney duly authorized in writing) and
the Company shall execute and the Trustee shall authenticate and deliver to the
Holder of such Note, without service charge, a new Note or Notes of any
authorized denomination as requested by such Holder in an aggregate principal
amount equal to, and in exchange for, the portion of the principal amount of the
Note so surrendered which is not purchased, or in the case of a Global Note, the
Company shall instruct the Registrar to decrease such Global Note by the
principal amount of the purchased portion of the Note surrendered.

      

      SECTION
5.12. Covenant to
Comply with Securities Laws Upon Purchase of Securities. When complying
with the provisions of Section 5.8 hereof (provided that such offer or purchase
constitutes an “issuer tender offer” for purposes of Rule 13e-4 (which term, as
used herein, includes any successor provision thereto) under the Exchange Act at
the time of such offer or purchase), the Company shall (a) comply with Rule
13e-4 and Rule 14e-1 (or any successor provision) under the Exchange Act and
comply with any other tender offer rules under the Exchange Act to the extent
applicable, (b) file a Schedule TO (or any successor schedule, form or report)
under the Exchange Act, if required and (c) otherwise comply with any applicable
Federal and state securities laws to the extent applicable to the Company so as
to permit the rights and obligations under Section 5.8 to be exercised in the
time and in the manner specified in Section 5.8.

      
        
           

        

        
          36

          
            

          

        

        
           

        

      

       

      SECTION
5.13. Repayment to the
Company. Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall return to the Company any cash held by the Trustee or
the Paying Agent, as applicable, for the payment of the Purchase Price or
Fundamental Change Purchase Price, as the case may be, that remains unclaimed by
the Holders for a period of two years; provided, however, that to
the extent that the aggregate amount of cash deposited by the Company pursuant
to Section 5.10 exceeds the aggregate Purchase Price or Fundamental Change
Purchase Price, as the case may be, of the Notes or portions thereof which the
Company is obligated to purchase as of the Business Day following the Purchase
Date or Fundamental Change Purchase Date, as the case may be, then, unless
otherwise agreed in writing with the Company, promptly after the Business Day
following the Purchase Date or Fundamental Change Purchase Date, as the case may
be, the Trustee or the Paying Agent shall return any such excess to the
Company.

      

      SECTION
5.14. No Fundamental
Change Purchase Following Acceleration. No Notes will be purchased by the
Company under Section 5.8 if the principal amount of the Notes has been
accelerated under this Indenture, and such acceleration has not be rescinded, on
or prior to the Fundamental Change Purchase Date.

      

      ARTICLE
VI CONVERSION OF NOTES

      

      SECTION
6.1. Conversion Right
and Conversion Rate.

      

      (a)   Subject
to and upon compliance with the provisions of this Article VI, at the option of
the Holder thereof, at any time prior to the close of business on the business
day immediate prior to Maturity, unless the Notes have been earlier redeemed or
repurchased by the Company, all or any portion of the principal amount of any
Note that is an integral multiple of $1,000 (provided that the principal
amount of such Note to remain outstanding after such conversion is equal to
$1,000 or any integral multiple of $1,000 in excess thereof) may be converted
into fully paid and non-assessable shares of Common Stock at the Conversion
Rate, determined as hereinafter provided, in effect at the time of
conversion.

      

      (b)   If
any Holder has submitted Notes for repurchase upon a Fundamental Change in
accordance with Section 5.8(c) hereof, such Notes submitted for repurchase may
be converted only if such Holder withdraws the election for repurchase in
accordance with Section 5.9 hereof.

      
        
           

        

        
          37

          
            

          

        

        
           

        

      

      

      (c) Each
$1,000 principal amount of notes converted into shares of Common Stock shall
initially be converted at a Conversion Price of $23.51 per share of Common
Stock. The initial rate at which shares of Common Stock shall be delivered upon
conversion (herein called the “Conversion Rate”) shall be
approximately 42.5351 shares of Common Stock for each $1,000 principal amount of
Notes. The Applicable Conversion Price will be adjusted under the circumstances
provided in Section 6.5. An adjustment to the Applicable Conversion Price will
result in a corresponding inverse adjustment to the Applicable Conversion Rate.
All calculations under this Article shall be made to the nearest 1/10th cent or
to the nearest 1/10,000ths of a share, as the case may be.

      

      SECTION
6.2. Conversion
Consideration.

      

      Upon
surrendering any Notes for conversion, the Holder of such Notes shall receive,
in respect of each $1,000 principal amount of Notes, a number of shares of
Common Stock equal to the Applicable Conversion Price.

      

      SECTION
6.3. Exercise of
Conversion Right.

      

      (a) In
order to exercise the conversion right:

      

      (1)   the
Holder of any Certificated Note to be converted must: (i) complete and manually
sign a notice of conversion substantially in the form of Exhibit B hereto (the
“Conversion Notice”);
(ii) deliver the Conversion Notice and the Certificated Note to the Conversion
Agent; and (iii) if required by the Company, the Trustee or the Conversion
Agent, furnish appropriate endorsements and transfer documents; or

      

      (2)   the
holder of beneficial interests in any Global Note to be converted must submit
the Conversion Notice and comply with the Applicable Procedures to cause the
beneficial interests in such Global Note to be delivered to the Conversion
Agent, and in either case, the Holder of a Certificated Note or holder of
beneficial interests in a Global Note will, if required, pay all transfer or
similar taxes that the Company is not otherwise required to pay pursuant to
Section 3.6 hereof and, if required pursuant to Section 6.3(b) hereof, pay funds
equal to the interest payable on the next Interest Payment Date.

      

      The date
on which a Holder of a Certificated Note or holder of a beneficial interest in a
Global Note completes the requirements of this Section 6.3(a) shall be deemed to
be the date of conversion (the “Conversion Date”) for purposes
of this Article VI, provided
that if the holder complies with such requirements after 11:00 a.m. (New
York City Time) on such date then the Conversion Date shall be the next
succeeding Business Day if the requirements are satisfied after 11:00 a.m. (New
York City Time). On and after the Conversion Date, the conversion by such Holder
or holder, as set forth in the Conversion Notice, shall become
irrevocable.

      

      The
Company shall deliver shares of Common Stock (and any cash in lieu of fractional
shares) deliverable upon conversion through the Conversion Agent no later than
the third Business Day following the Conversion Date.

      
        
           

        

        
          38

          
            

          

        

        
           

        

      

      

      (b)   Each
Certificated Note surrendered (in whole or in part), or beneficial interest in
any  Global Note surrendered to the Conversion Agent, for conversion
during a Record Date Period  shall be accompanied by payment by the
Holder in same-day funds or other funds acceptable to  the Company of
an amount equal to the interest payable on the applicable Interest Payment
Date  on the principal amount of such Note (or part thereof, as the
case may be) being surrendered for  conversion; provided, however, that no
such payment by the Holder need be made (1) if the  Notes have been
called by the Company for redemption and the Redemption Date is after
a  Record Date and on or prior to the next Interest Payment Date, (2)
if we have specified a  Purchase Date following a Fundamental Change
that is after a Record Date and on or prior to the  next Interest
Payment Date, (3) with respect to any Note surrendered for conversion
following  the Record Date for the payment of interest (including
Liquidated Damaged and Additional  Amounts, if any) immediately
preceding the Stated Maturity, or (4) only to the extent of  Defaulted
Interest, if any Defaulted Interest exists at the time of conversion with
respect to such Note.

      

      Except as
provided in this Section 6.3(b), no cash payment or adjustment shall be made
upon any conversion on account of any interest accrued from the Interest Payment
Date immediately prior to the Conversion Date, in respect of any Note (or part
thereof, as the case may be) surrendered for conversion. The Company’s delivery
to the Holder of the number of shares of Common Stock (and cash in lieu of
fractions thereof in accordance with Section 6.4 hereof) into which a Note is
convertible will be deemed to satisfy all of the Company’s obligations to pay
the principal and accrued and unpaid interest (including Liquidated Damages and
Additional Interest), if any, on the Note. Accordingly, accrued but unpaid
interest, if any, will be deemed to be paid in full rather than cancelled,
extinguished or forfeited.

      

      (c)   Notes
shall be deemed to have been converted immediately prior to the close
of  business on the Conversion Date, and at such time the rights of
the Holders of such Notes as  Holders shall cease, and the Person or
Persons entitled to receive the shares of Common Stock  issuable upon
conversion shall be treated for all purposes as the record holder or Holders of
such  Common Stock at such time. Following any Conversion Date, the
Company shall satisfy its  obligations with respect to such conversion
by either:

      

      (1)   delivering
to the Conversion Agent, for delivery to the Holder (or such other Person as may
be named in the relevant Conversion Notice), certificates representing the
number of shares of Common Stock issuable upon such conversion; or

      

      (2)   delivering
to such Holder (or such other Person as may be named in the relevant Conversion
Notice) such number of shares of Common Stock issuable upon such conversion in
accordance with the Applicable Procedures,

      

      in each
case, together with payment in lieu of any fractional shares, if any, as
provided in Section 6.4 (such delivery of shares and cash payment, if any, the
“Settlement”); provided that shares of
Common Stock only will be deliverable in certificated form if (i) the Holder
exercising such conversion has specifically requested in writing that delivery
be in certificates or (ii) the Company determines that delivery is required in
certificated shares either because (A) delivery to the Holder (or such other
Person named in the relevant Conversion Notice) is not practicable in accordance
with the Applicable Procedures or (B) in the opinion of legal counsel, delivery
is required in certificated form in order to comply with the requirements of
applicable securities laws.

      
        
           

        

        
          39

          
            

          

        

        
           

        

      

      

      (d) In
the case of any Note that is converted in part only, upon such conversion the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder thereof, at the expense of the Company, a new Note or Notes of authorized
denominations in an aggregate principal amount equal to the unconverted portion
of the principal amount of such Note.

      

      SECTION
6.4. Fractions of
Shares. No fractional shares of Common Stock shall be issued upon
conversion of any Note or Notes. 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 issuable upon conversion thereof shall be computed on the basis of the
aggregate principal amount of the Notes (or specified portions thereof) so
surrendered. The number of fractional shares to be paid, if any, will be valued
by the Closing Sale Price of the Common Stock on the Trading Day immediately
preceding the Conversion Date. Instead of any fractional share of Common Stock
that would otherwise be issuable upon conversion of any Note or Notes (or
specified portions thereof), the Company shall calculate and pay to the Paying
Agent a cash adjustment for the fractional amount (calculated to the nearest
1/10,000th of a share) based upon the Closing Sale Price on the Trading Day
immediately preceding the Conversion Date.

      

      SECTION
6.5. Applicable
Conversion Price Adjustments.

      

      (a) The
Applicable Conversion Price shall be adjusted from time to time by the Company
as follows:

      

      (1)   In
case the Company shall (i) pay a dividend on its Common Stock in shares of
Common Stock, (ii) make a distribution on its Common Stock in shares of Common
Stock, (iii) subdivide its outstanding Common Stock into a greater number of
shares, or (iv) combine its outstanding Common Stock into a smaller number of
shares, the Applicable Conversion Price in effect immediately prior to thereto
shall be adjusted so that the Holder of any Note thereafter surrendered for
conversion shall be entitled to receive that number of shares of Common Stock
which it would have owned had such Note been converted immediately prior to the
record date of such event or the happening of such event. An adjustment made
pursuant to this subsection (a) shall become effective on the “ex” date in the
case of a dividend or distribution and shall become effective immediately after
the effective date in the case of a subdivision or combination. If any dividend
or distribution of the type described in this Section 6.5(a)(1) is declared but
not actually paid or made, the Applicable Conversion Price shall again be
adjusted to the Applicable Conversion Price that would have been in effect if
such dividend or distribution had not been declared.

      

      (2)   In
case the Company shall issue rights or warrants to all or substantially all
Holders of its Common Stock entitling them for a period of not more than 60 days
to subscribe for or purchase shares of Common Stock (or securities convertible
into Common Stock) at a price per share (or having a Applicable Conversion Price
per share) less than the Current Market Price per share of Common Stock on the
Trading Day immediately preceding the “ex” date for such issuance, the
Applicable Conversion Price shall be adjusted so that the Applicable Conversion
Price on the “ex” date shall equal the price determined by multiplying the
Applicable Conversion Price in effect immediately prior to such “ex” date by a
fraction of which the numerator shall be the number of shares of Common Stock
Outstanding immediately prior to such “ex” date plus the number of shares which
the aggregate offering price of the total number of shares of Common Stock so
offered for subscription or purchase (or the aggregate Applicable Conversion
Price of the convertible securities so offered, which shall be determined by
multiplying the number of shares of Common Stock issuable upon conversion of
such convertible securities by the Applicable Conversion Price per share of
Common Stock pursuant to the terms of such convertible securities) would
purchase at the Current Market Price per share of Common Stock on the Trading
Day immediately preceding such “ex” date, and of which the denominator shall be
the number of shares of Common Stock outstanding on such record date plus the
number of additional shares of Common Stock offered for subscription or
purchase. Such adjustment shall be made successively whenever any such rights or
warrants are issued and shall become effective immediately after the opening of
business on such “ex” date. If at the end of the period during which such rights
or warrants are exercisable not all rights or warrants shall have been exercised
or distributed, the adjusted Applicable Conversion Price shall be immediately
readjusted to what it would have been based upon the number of additional shares
of Common Stock actually issued (or the number of shares of Common Stock
issuable upon conversion of convertible securities actually
issued).

       

      
        
          
          

        

        
          40

          
            

          

        

        
          
          

        

      

       

      (3)    In
case the Company shall distribute to all or substantially all Holders of its
Common Stock any shares of Capital Stock of the Company (other than Common
Stock), evidences of Indebtedness or other non-cash assets (including securities
of any Person other than the Company) or rights or warrants to subscribe for or
purchase any of its securities (but excluding from this Section 6.5(a)(3): (i)
dividends or distributions paid exclusively in Cash referred to in subsection
(4) or (6) of this Section 6.5(a); (ii) dividends or distributions referred to
in subsection (1) or (5) of this Section 6.5(a); (iii) those rights and warrants
referred to in subsection (2) of this Section 6.5(a); and (iv) rights to all or
substantially all Holders of Common Stock pursuant to the adoption of a
shareholder rights plan or the detachment of such rights under the terms of such
shareholder rights plan), then in each such case the Applicable Conversion Price
shall be adjusted so that the Applicable Conversion Price on the “ex” date for
such distribution shall equal the price determined by multiplying the current
Applicable Conversion Price by a fraction of which the numerator shall be the
Current Market Price per share of the Common Stock on the Trading Day
immediately preceding such “ex” date less the fair market value on such Trading
Day (as determined by the Board of Directors, whose determination shall be
conclusive evidence of such fair market value and which shall be evidenced by an
Officers’ Certificate delivered to the Trustee and the Conversion Agent) of the
portion of the Capital Stock, evidences of Indebtedness or other non-cash assets
so distributed or of such rights or warrants applicable to one share of Common
Stock (determined on the basis of the number of shares of Common Stock
outstanding on the Trading Day immediately preceding such “ex” date), and of
which the denominator shall be the Current Market Price per share of the Common
Stock on the Trading Day immediately preceding such “ex” date. Such adjustment
shall be made successively whenever any such distribution is made and shall
become effective immediately after the record date for the determination of
shareholders entitled to receive such distribution.

      
        
           

        

        
          41

          
            

          

        

        
           

        

      

      

      In the
event the then fair market value (as so determined) of the portion of the
Capital Stock, evidences of Indebtedness or other non-cash assets so distributed
or of such rights or warrants applicable to one share of Common Stock is equal
to or greater than the Current Market Price per share of the Common Stock on the
Trading Day immediately preceding such “ex” date, in lieu of the foregoing
adjustment, adequate provision shall be made so that each holder of a Note shall
have the right to receive upon conversion the amount of Capital Stock, evidences
of Indebtedness or other non-cash assets so distributed or of such rights or
warrants such holder would have received had such holder converted each Note
immediately prior to the record date for such distribution. In the event that
such dividend or distribution is not so paid or made, the Applicable Conversion
Price shall again be adjusted to be the Applicable Conversion Price which would
then be in effect if such dividend or distribution had not been declared. If the
Board of Directors determines the fair market value of any distribution for
purposes of this Section 6.5(a)(3) 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 Current Market Price of
the Common Stock.

      

      In the
event that the Company implements a preferred shares rights plan (“Rights Plan”), upon conversion
of the Notes into Common Stock, to the extent that the Rights Plan has been
implemented and is still in effect upon such conversion, the Holders of Note
will receive, in addition to the Common Stock, the rights described therein
(whether or not the rights have separated from the Common Stock at the time of
conversion), subject to the limitations set forth in the Rights Plan. Any
distribution of rights or warrants pursuant to a Rights Plan complying with the
requirements set forth in the immediately preceding sentence of this paragraph
shall not constitute a distribution of rights or warrants pursuant to this
Section 6.5(a)(3).

      

      (4)   In
case the Company shall, by dividend or otherwise, at any time distribute (a
“Triggering
Distribution”) to all or substantially all Holders of its Common Stock,
Cash dividends and other Cash distributions (other than (y) distributions
described in Section 6.5(a)(6) below or (z) any dividend or distribution in
connection with liquidation, dissolution or winding up), the Applicable
Conversion Price shall be reduced so that the same shall equal the price
determined by multiplying such Applicable Conversion Price in effect on the
Trading Day immediately preceding the “ex” date with respect to such Cash
dividend or distribution by a fraction of which (A) the numerator shall be the
Closing Sale Price per share of the Common Stock as of the Trading Day
immediately preceding the “ex” date with respect to the dividend or distribution
less the Dividend Adjustment Amount, and (B) the denominator shall be the
Closing Sale Price per share of the Common Stock as of the Trading Day
immediately preceding the “ex” date with respect to the dividend or
distribution. Such decrease shall become effective immediately prior to the
opening of business on the “ex” date for such dividend or distribution; provided, however, that, in
the event the portion of the Triggering Distribution applicable to one share of
Common Stock is equal to or greater than the Closing Sale Price on such record
date, in lieu of the foregoing adjustment, adequate provision shall be made so
that each Holder shall have the right to receive upon conversion the amount of
Cash such Holder would have received had such Holder converted each Note
immediately prior to the record date for such dividend or distribution. In the
event that such dividend or distribution is not so paid or made, the Applicable
Conversion Price shall again be adjusted to be the Applicable Conversion Price
that would then be in effect if such dividend or distribution had not been
declared.

      
        
           

        

        
          42

          
            

          

        

        
           

        

      

      

      (5)   In
the case the Company shall distribute shares of Capital Stock or similar equity
interests of any Subsidiary or business unit, (a “Spin-Off”), then in each such
case the Applicable Conversion Price shall be adjusted so that the Applicable
Conversion Price in effect immediately before the close of business on the
Trading Day immediately preceding the “ex” date with respect to that
distribution will be decreased by multiplying the Applicable Conversion Price by
a fraction (A) the numerator of which is the average of the Closing Sale Prices
of a share of Common Stock on each of the 10 consecutive Trading Days beginning
on the effective date of the spin-off and (B) the denominator of which is the
average of the Closing Sale Prices of a share of Common Stock on each of the 10
consecutive Trading Days beginning on the effective date of the Spin-Off plus
the average of the closing sale prices of the portion of those shares of capital
stock or similar equity interests so distributed applicable to one share of
Common Stock on each of those 10 consecutive Trading Days, provided, that for any
conversion within the 10 consecutive Trading Days following, and including, the
effective date of the Spin-Off, the adjustment to the Applicable Conversion
Price shall be calculated by reference to the number of consecutive Trading Days
between the effective date of the such Spin-Off and the Conversion Date rather
than 10 Trading Days.

      

      (6)   In
case any tender offer made by the Company or any of its Subsidiaries for Common
Stock shall expire and such tender offer (as amended upon the expiration
thereof) shall involve the payment of aggregate consideration in an amount
(determined as the sum of the aggregate amount of Cash consideration and the
aggregate fair market value (as determined by the Board of Directors, whose
determination shall be conclusive evidence thereof and which shall be evidenced
by an Officers’ Certificate delivered to the Trustee and the Conversion Agent
thereof) of any other consideration) that exceeds an amount equal to the Current
Market Price per share of Common Stock as of the last date (the “Expiration Date”) tenders
could have been made pursuant to such tender offer (as it may be amended) (the
last time at which such tenders could have been made on the Expiration Date is
hereinafter called the “Expiration Time”), then,
immediately prior to the opening of business on the day after the Expiration
Date, the Applicable Conversion Price shall be reduced so that the same shall
equal the price determined by multiplying the Applicable Conversion Price in
effect immediately prior to 5:00 p.m. (New York City time) on the Expiration
Date by a fraction of which (A) the numerator shall be the product of the number
of shares of Common Stock outstanding (including tendered shares but excluding
any shares held in the treasury of the Company) immediately before the
Expiration Time multiplied by the Current Market Price per share of the Common
Stock on the Trading Day next succeeding the Expiration Date and (B) the
denominator shall be the sum of (x) the aggregate consideration (determined as
aforesaid) payable to stockholders based on the acceptance (up to any maximum
specified in the terms of the tender offer) of all shares validly tendered and
not withdrawn as of the Expiration Time (the shares deemed so accepted, up to
any such maximum, being referred to as the “Purchased Shares”) and (y) the
product of the number of shares of Common Stock outstanding (less any Purchased
Shares and excluding any shares held in the treasury of the Company) immediately
after the Expiration Time and the Current Market Price per share of Common Stock
on the Trading Day next succeeding the Expiration Date. In the event that the
Company is obligated to purchase shares pursuant to any such tender offer, but
the Company is permanently prevented by applicable law from effecting any or all
such purchases or any or all such purchases are rescinded, the Applicable
Conversion Price shall again be adjusted to be the Applicable Conversion Price
which would have been in effect based upon the number of shares actually
purchased. If the application of this Section 6.5(a)(6) to any tender offer
would result in an increase in the Applicable Conversion Price, no adjustment
shall be made for such tender offer under this Section
6.5(a)(6).

      
        
           

        

        
          43

          
            

          

        

        
           

        

      

      

      For
purposes of this Section 6.5(a)(6), the term “tender offer” shall mean and
include both tender offers and exchange offers, all references to “purchases” of
shares in tender offers (and all similar references) shall mean and include both
the purchase of shares in tender offers and the acquisition of shares pursuant
to exchange offers, and all references to “tendered shares” (and all similar
references) shall mean and include shares tendered in both tender offers and
exchange offers.

      

      For the
avoidance of any doubt, any adjustments to the Applicable Conversion Price
pursuant to this section shall be made through the date on which payment
pursuant to Section 6.2 is made (without regard to the intervening occurrence of
the Stated Maturity, should that occur).

      

      (b)   No Adjustment.
Notwithstanding the provisions of Section 6.5(a), no adjustment in the
Applicable Conversion Price shall be required unless the adjustment would result
in a change of at least 1% in the Applicable Conversion Price as last adjusted;
provided, however, that
any adjustments which by reason of this Section 6.5(b) are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment, regardless of whether the aggregate adjustment is less than 1%,
within one year of the first such adjustment carried forward, upon redemption of
the Notes by the Company, upon required purchases of the Notes in connection
with a Fundamental Change and five Business Days prior to Maturity. Except as
otherwise provided herein, the Applicable Conversion Price will not be adjusted
for the issuance of Common Stock or any securities convertible into or
exchangeable for Common Stock or carrying the right to purchase Common Stock or
any such security. No adjustment to the Applicable Conversion Price will be
required in respect of any transaction that Holders will participate in without
conversion of the Notes. The Company will promptly provide notice of any such
adjustment to the Trustee and the Conversion Agent.

      

      (c)   Reduction in the Applicable
Conversion Price due to Taxes. The Company shall be entitled to make such
reductions in the Applicable Conversion Price, for the remaining term of the
Notes or any shorter term, in addition to those required by clause (a) of this
Section 6.5, as the Board of Directors of the Company considers to be advisable
in order to avoid or diminish any income tax to any holders of shares of Common
Stock or rights to purchase Common Stock resulting from any stock dividend or
distribution, subdivision of shares, distribution of rights or warrants to
purchase or subscribe for stock or securities, distributions of securities
convertible into or exchangeable for stock hereafter made by the Company to its
stockholders or from any event treated as such for income tax purposes. The
Company shall have the power to resolve any ambiguity or correct any error in
this clause (c) and its actions in so doing shall, absent manifest error, be
final and conclusive.

      
        
           

        

        
          44

          
            

          

        

        
           

        

      

      

      (d)   Temporary Reduction in the
Applicable Conversion Price. To the extent permitted by applicable law
and rules of any stock exchange on which the Common Stock is then listed, the
Company from time to time may reduce the Applicable Conversion Price by any
amount for any period of time if the period is at least 20 Business Days and the
Board of Directors shall have made a determination that such reduction would be
in the best interest of the Company. Whenever the Applicable Conversion Price is
reduced pursuant to the preceding sentence, the Company shall provide notice of
any reduction in the Applicable Conversion Price to the Holders in the manner
provided in the Indenture, with a copy to the Trustee and Conversion Agent, at
least 15 days prior to the date such reduced Applicable Conversion Price takes
effect, and such notice shall state the reduced Applicable Conversion Price and
the period during which it will be in effect.

      

      (e)   Qualifying Fundamental
Change Make-Whole Adjustment. If a Qualifying Fundamental Change occurs
prior to March 15, 2013, upon conversion of the Notes pursuant to Section 5.8,
the Applicable Conversion Price of the Notes being converted by such Holder at
that time shall be decreased, which will cause the Applicable Conversion Rate to
increase by an additional number of shares of Common Stock (the “Additional Shares”) determined
by reference to the table below.

       

      (1)   For
the avoidance of doubt, the adjustment provided for in this Section 6.5(e) shall
be made only with respect to the Notes converted in connection with such
Qualifying Fundamental Change and shall not be effective as to any Notes not so
converted. Conversion of a given Note shall be considered to be “in connection
with” a given Fundamental Change if that Note is surrendered for conversion
during the conversion period provided for in respect of such Fundamental Change
pursuant to Section 6.1(b). The adjustment provided for in this Section 6.5(e)
shall be made only if the Qualifying Fundamental Change actually occurs or
becomes effective.

      

      (2)   For
purposes of determining the applicable number of Additional Shares:

      

      (i)
“Effective Date” shall
mean the date the Qualifying Fundamental Change occurs or becomes effective;
and

      

      (ii)
“Stock Price” shall
mean:

      

      (A)   in
the case of a Qualifying Fundamental Change described in clause (ii) of the
definition of Change in Control, the price paid per share of Common Stock in the
Change in Control, unless the holders of Common Stock receive only Cash in such
Qualifying Fundamental Change, in which event “Stock Price” shall mean the Cash
amount paid per share; and

      

      (B)   in
the case of any Qualifying Fundamental Change described in clause (i) or (ii) of
the definition of Change of Control, the average of the last reported Closing
Sale Prices of Common Stock over the five consecutive Trading Day period ending
on the Trading Day preceding the Effective Date of such Qualifying Fundamental
Change.

      
        
           

        

        
          45

          
            

          

        

        
           

        

      

      

      The
following table expressly sets forth the increase in the Conversion Rate,
expressed as a number of Additional Shares to be added per $1,000 initial
principal amount of Notes as a result of a Fundamental Change.

      The Stock
Prices and Additional Share amounts set forth above are based upon an Initial
Conversion Price of $23.51. The Stock Prices set forth in the first row of the
table above shall be adjusted as of any date on which the Applicable Conversion
Price of the Notes is adjusted in accordance with Section 6.5(a) and shall be
adjusted by the same adjustment factor applied to the Applicable Conversion
Price pursuant to Section 6.5(a). The number of Additional Shares shall be
adjusted by the inverse application of the adjustment factor applied to the
Applicable Conversion Price pursuant to Section 6.5(a).

      

      Notwithstanding
anything in the Indenture to the contrary, the Company may not increase the
conversion rate to more than 54.4365 per $1,000 initial principal amount of the
Notes pursuant to the events described in this Section 6.5(e) (subject to
adjustment in the same manner as the Applicable Conversion Price in Section
6.5(a), by the inverse of the adjustment factor applied to the Applicable
Conversion Price in that section).

      

      If the
Stock Price is between two Stock Prices in the table or the Fundamental Change
Effective Date is between two Effective Dates in the table, the number of
Additional Shares will be determined by straight-line interpolation between the
number of Additional Shares set forth for the higher and lower Stock Prices and
the two Effective Dates, as applicable, based on a 365-day year. If the Stock
Price is in excess of $80.00 per share (subject to adjustment as set forth
herein), or if the Stock Price is less than $18.37 per share (subject to
adjustment as set forth herein), no Additional Shares will be added to the
Applicable Conversion Rate.

      

      (3)   The
Company will notify Holders, the Trustee and the Conversion Agent of the
anticipated Effective Date of such Qualifying Fundamental Change and issue a
press release as soon as practicable after the Company first determines the
anticipated Qualifying Fundamental Change Effective Date.

      

      (4)   Notwithstanding
Section 6.5 hereof, if a Holder surrenders the Notes for conversion in
connection with a Qualifying Fundamental Change, the Company will deliver the
portion of the conversion consideration that is payable on account of the
increase in the Conversion Rate pursuant to this Section 6.5(e) as soon as
practicable, but in no event after the third Business Day after the later of (i)
the date the Holder surrenders the Notes for conversion; or (ii) the Effective
Date of the Qualifying Fundamental Change.

      
        
           

        

        
          46

          
            

          

        

        
           

        

      

      

      (5) If a
Holder surrenders Notes in connection with a Qualifying Fundamental Change
announced by the Company, but such Qualifying Fundamental Change is not
consummated, then such Holder shall not be entitled to the increased Conversion
Rate pursuant to this Section 6.5(e).

      

      SECTION
6.6. Notice of
Adjustments of Conversion Price. Whenever the Applicable Conversion Price
is adjusted pursuant to Section 6.5 hereof:

      

      (a)   the
Company shall compute the adjusted Applicable Conversion Price in accordance
with Section 6.5 hereof and shall prepare an Officers’ Certificate setting forth
(1) the adjusted Applicable Conversion Price, (2) the clause of Section 6.5
pursuant to which such adjustment has been made, showing in reasonable detail
the facts upon which such adjustment is based, (3) the calculation of such
adjustment and (4) the date as of which such adjustment is effective, and such
certificate shall promptly be delivered to the Trustee and the Conversion Agent
(which such certificates shall be conclusive absent manifest error);
and

      

      (b)   upon
each such adjustment, a notice stating that the Applicable Conversion Price has
been adjusted and setting forth the adjusted Applicable Conversion Price shall
be required, and as soon as practicable after it is required, such notice shall
be provided by the Company to all Holders in accordance with Section
11.2.

      

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

      

      SECTION
6.7. Limitation on
Adjustments.

      

      (a)   The
Company shall not take any action that would result in an adjustment pursuant to
the foregoing provisions in this Article VI without complying with the rules of
any stock exchange on which the Common Stock is then listed (including, if
applicable, New York Stock Exchange rules requiring stockholder approval of
certain issuance of stock).

      

      (b)   The
Company shall not take any action that would result in an adjustment pursuant to
the foreign provisions of this Article VI if that adjustment would reduce the
Applicable Conversion Price below the then par value of the shares of Common
Stock issuance upon conversion of the Notes.

      

      SECTION
6.8. Effect of
Reclassification, Consolidation, Merger or Sale on Conversion
Privilege.

      

      (a) If
any of the following shall occur, namely: (i) any reclassification or change of
shares of Common Stock issuable upon conversion of the Notes (other than a
change in par value, or from par value to no par value, or from no par value to
par value, or as a result of a subdivision or combination, or any other change
for which an adjustment is provided in Section 6.5); (ii) any consolidation or
merger or combination to which the Company is a party other than a merger in
which the Company is the continuing corporation and which does not result in any
reclassification of, or change (other than in par value, or from par value to no
par value, or from no par value to par value, or as a result of a subdivision or
combination) in, outstanding shares of Common Stock; or (iii) any sale or
conveyance as an entirety or substantially as an entirety of the property and
assets of the Company, directly or indirectly, to any person, the Company, or
such successor, purchasing or transferee corporation, as the case may be, shall,
as a condition precedent to such reclassification, change, combination,
consolidation, merger, sale or conveyance, execute and deliver to the Trustee a
supplemental indenture providing that the Holder of each Note then outstanding
shall have the right to convert such Note into the kind and amount of shares of
stock and other securities and property (including Cash) receivable upon such
reclassification, change, combination, consolidation, merger, sale or conveyance
by a Holder of the number of shares of Common Stock deliverable upon conversion
of such Note immediately prior to such reclassification, change, combination,
consolidation, merger, sale or conveyance (the “Reference Property”). Such
supplement indenture shall provide for adjustments of the Applicable Conversion
Price which shall be as nearly equivalent as may be practicable to the
adjustments of the Applicable Conversion Price provided for in this Article VI.
If, in the case of any such consolidation, merger, combination, sale or
conveyance, the stock or other securities and property (including Cash)
receivable thereupon by a Holder of Common Stock include shares of stock or
other securities and property of a person other than the successor, purchasing
or transferee corporation, as the case may be, in such consolidation, merger,
combination, sale or conveyance, then such supplemental indenture shall also be
executed by such other person and shall contain such additional provisions to
protect the interests of the Holders of the Notes as the Board of Directors
shall reasonably consider necessary by reason of the foregoing. The provisions
of this Section 6.8 shall similarly apply to successive reclassifications,
changes, combinations, consolidations, mergers, sales or conveyances. The
Trustee has no duty to determine whether a supplemental indenture under this
Section 6.8 need be entered into.

      
        
           

        

        
          47

          
            

          

        

        
           

        

      

      

      In the
event the Company shall execute a supplemental indenture pursuant to this
Section 6.8, the Company shall promptly file with the Trustee (x) an Officers’
Certificate briefly stating the reasons therefor, the kind or amount of shares
of stock or other securities or property (including Cash) receivable by Holders
of the Notes upon the conversion of their Notes after any such
reclassifications, change, combination, consolidation, merger, sale or
conveyance, any adjustment to be made with respect thereto and that all
conditions precedent have been complied with and (y) an Opinion of Counsel that
all conditions precedent have been complied with, and shall promptly mail notice
of such supplemental indenture to all Holders.

      

      Throughout
this Article VI, if Common Stock has been replaced by Reference Property as a
result of any reclassification, change, combination, consolidation, merger, sale
or conveyance, references to Common Stock shall be changed to Reference
Property.

      

      (b) In
the event that Holders of Common Stock have the opportunity to elect the form of
consideration to be received in any transaction described in Section 6.8(a), the
Company shall make adequate provision so that the Holders of the Notes, treated
as a single class, have the timely opportunity to determine the composition of
the Reference Property that will replace any Common Stock that would otherwise
be deliverable upon conversion of the Notes. The Reference Property will be
based on the blended, weighted average of elections made by Holders of the Notes
and will be subject to any limitations applicable to all Holders of Common Stock
(such as pro rata reductions made to any portion of the consideration payable).
The determination of the Reference Property will apply to all of the Notes and
the Company shall notify the Trustee of the composition of the Reference
Property promptly after it is determined.

      
        
           

        

        
          48

          
            

          

        

        
           

        

      

      

      All
calculations under this Article VI shall be made to the nearest 1/10,000th of a
share, as the case may be. The Company will not take any action that would
result in an adjustment pursuant to this Article VI without complying with the
shareholder approval rules of The New York Stock Exchange or any stock exchange
on which the Common Stock is listed at the relevant time.

      

      SECTION
6.9. Rights Issued in
Respect of Common Stock. Rights or warrants distributed by the Company to
all holders of Common Stock entitling the holders thereof to subscribe for or
purchase shares of the Company’s Capital Stock (either initially or under
certain circumstances), which rights or warrants, until the occurrence of a
specified event or events (“Trigger Event”):

      

      (1)   are
deemed to be transferred with such shares of Common Stock;

      

      (2)   are
not exercisable; and

      

      (3)   are
also issued in respect of future issuances of Common Stock,

      

      shall not
be deemed distributed for purposes of Section 6.5(a) (and no adjustment to the
Applicable Conversion Price under Section 6.5(a) 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 Applicable Conversion Price shall be made under Section
6.5(a) hereof. In addition, in the event of any distribution (or deemed
distribution) of rights or warrants, or any Trigger Event or other event (of the
type described in the preceding sentence) with respect thereto that was counted
for purposes of calculating a distribution amount for which an adjustment to the
Applicable Conversion Price under Section 6.5(a) hereof was made, (1) in the
case of any such rights or warrants which shall all have been redeemed or
purchased without exercise by any holders thereof, the Applicable Conversion
Price shall be readjusted upon such final redemption or purchase to give effect
to such distribution or Trigger Event, as the case may be, as though it were a
Cash distribution, equal to the per share redemption or purchase price received
by a holder or holders of Common Stock with respect to such rights or warrants
(assuming such holder had retained such rights or warrants), made to all holders
of Common Stock as of the date of such redemption or purchase, and (2) in the
case of such rights or warrants which shall have expired or been terminated
without exercise by any holders thereof, the Applicable Conversion Price shall
be readjusted as if such rights and warrants had not been issued. If any such
right or warrant, including any such existing rights or warrants distributed
prior to the date of this Indenture, are subject to events, upon the occurrence
of which such rights or warrants become exercisable to purchase different
securities, evidences of Indebtedness or other assets, then the date of the
occurrence of any and each such event shall be deemed to be the date of
distribution and record date with respect to new rights or warrants with such
rights (and a termination or expiration of the existing rights or warrants
without exercise by any of the holders thereof).

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

Significant Subsidiaries in an outstanding principal amount in excess of

Indebtedness as such final maturity of such indebtedness may be extended by

          50

          
            

          

        

        
           

        

      

      (8)   the
Company or any of its Significant Subsidiaries fail to pay one or more final and
non-appealable judgments entered by a court or courts of competent jurisdiction,

and such judgments are not paid, discharged or stayed within 30

and

      (iv)
grants any similar relief under any applicable foreign or state laws and in each
such case the order or decree remains unstayed and in effect for 60
days.

      

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

      

      The term
“Custodian” means any
receiver, trustee, assignee, liquidator, custodian or similar official under any
Bankruptcy Law.

      
        
           

        

        
          51

          
            

          

        

        
           

        

      

      

      The
Company shall deliver to the Trustee, as promptly as reasonably practicable and
in any event within 30 days after the occurrence thereof, written notice in the
form of an Officers’ Certificate of any Event of Default and any Default of
which the Company is aware, the status of any such Event of Default or any
Default and what action the Company is taking or proposes to take with respect
thereto.

      

      SECTION
7.2. Acceleration. Except
as provided in Section 7.13, if an Event of Default (other than an Event of
Default specified in Section 7.1(9) or Section 7.1(10) with respect to the
Company and except as otherwise provided in Section 7.13) occurs and is
continuing, the Trustee by notice to the Company, or the Holders of at least 25%
in aggregate principal amount of the Notes then outstanding by notice to the
Company and the Trustee, may declare the principal amount of Notes outstanding
plus accrued and unpaid interest, if any (including Liquidated Damages and
Additional Interest, if any), on all the outstanding Notes to be immediately due
and payable. Upon such a declaration, such accelerated amount shall be due and
payable immediately. If an Event of Default specified in Section 7.1(9) or
Section 7.1(10) with respect to the Company occurs and is continuing, the
principal amount of Notes outstanding plus accrued and unpaid interest, if any
(including Liquidated Damages and Additional Interest, if any), on all the Notes
shall, automatically and without any action by the Trustee or any Holder, become
and be immediately due and payable without any declaration or other act on the
part of the Trustee or any Holders. The Holders of a majority in an aggregate
principal amount of the Notes at the time outstanding by notice to the Trustee
and the Company and without notice to any other Holder may rescind any
declaration of acceleration if the rescission would not conflict with any
judgment or decree and if all existing Events of Default have been cured or
waived except nonpayment of the principal amount plus accrued and unpaid
interest, if any (including Liquidated Damages and Additional Interest, if any),
that have become due solely as a result of acceleration. No such rescission
shall affect any subsequent Default or impair any right consequent
thereto.

      

      SECTION
7.3. Other
Remedies. If an Event of Default occurs and is continuing, the Trustee
may pursue any available remedy to collect the payment of the principal amount
plus accrued and unpaid interest, if any (including Liquidated Damages and
Additional Interest, if any), on the Notes or to enforce the performance of any
provision of the Notes or this Indenture.

      

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

      

      SECTION
7.4. Waiver of Past
Defaults. Subject to Section 7.2 and Section 10.2 hereof, the Holders of
a majority in aggregate principal amount of the Notes at the time outstanding by
notice to the Trustee and without notice to any other Holder may waive any past
Default and its consequences except (a) an Event of Default described in Section
7.1(1) and Section 7.1(3), (b) a Default in respect of a covenant that under
Section 10.2 cannot be amended without the consent of each Holder, or (c) a
failure to pay shares of Common Stock upon conversion of any Note (including any
Additional Shares) within the time periods set forth in Section 6.3. When a
Default is waived, it is deemed cured, but no such waiver shall extend to any
subsequent or other Default or impair any consequent right.

      
        
           

        

        
          52

          
            

          

        

        
           

        

      

      

      SECTION
7.5. Control by
Majority. The Holders of a majority in aggregate principal amount of the
Notes at the time outstanding may direct in writing the time, method and place
of conducting any proceeding for any remedy available to the Trustee or of
exercising any trust or power conferred on the Trustee. However, the Trustee may
refuse to follow any direction that conflicts with law or this Indenture or,
subject to Section 8.1, that the Trustee determines is unduly prejudicial to the
rights of other Holders or would potentially involve the Trustee in personal
liability. Prior to taking any action hereunder, the Trustee shall be entitled
to indemnification satisfactory to the Trustee in its reasonable discretion
against all losses and expenses caused by taking or not taking such
action.

      

      SECTION
7.6. Limitation on
Suits. A Holder may not pursue any remedy with respect to this Indenture
or the Notes or for the appointment of a receiver or a Trustee, except in the
case of a suit instituted by a Holder for the enforcement of the payment of
principal or interest (including Liquidated Damages and Additional Interest, if
any), and only if:

      

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

      

      (b)   the
Holders of at least 25% in aggregate principal amount of the Notes at the time
outstanding make a written request, and such Holder or Holders shall have
offered reasonable indemnity to the Trustee to pursue such remedy;
and

      

      (c)   the
Trustee has failed to institute such proceeding within 60 days after such
written notice, request and offer and has not received from the Holders of a
majority in aggregate principal amount of the Notes then outstanding a direction
inconsistent with such request within 60 days after such written notice, request
and offer.

      

      A Holder
may not use this Indenture to prejudice the rights of any other Holder or to
obtain a preference or priority over any other Holder.

      

      SECTION
7.7. Rights of Holders
to Receive Payment. Notwithstanding any other provision of this
Indenture, the right of any Holder to receive payment of the principal amount,
Redemption Price, Purchase Price, Fundamental Change Purchase Price or interest,
if any (including Liquidated Damages and Additional Interest, if any), in
respect of the Notes held by such Holder, on or after the respective due dates
expressed in such Holder’s Notes or any Redemption Date, Purchase Date or
Fundamental Change Purchase Date, and to convert the Notes in accordance with
Article VI, or to bring suit for the enforcement of any such payment on or after
such respective dates or the right to convert, shall not be impaired or affected
without the consent of such Holder.

      

      SECTION
7.8. Collection Suit
by Trustee. If an Event of Default specified in Section 7.1(1) or Section
7.1(3) occurs and is continuing, the Trustee may recover judgment in its own
name and as trustee of an express trust against the Company for the whole amount
then due and owing (together with interest on any unpaid interest, including
Liquidated Damages and Additional Interest, to the extent lawful) and the
amounts provided for in Section 8.7.

      
        
           

        

        
          53

          
            

          

        

        
           

        

      

      

      SECTION
7.9. Trustee May File
Proofs of Claim. The Trustee may file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee and the Holders allowed in any judicial proceedings relative to
the Company, its creditors or its property and, unless prohibited by law or
applicable regulations, may vote on behalf of the Holders in any election of a
trustee in bankruptcy or other Person performing similar functions, and any
Custodian in any such judicial proceeding is hereby authorized by each Holder to
make payments to the Trustee and, in the event that the Trustee shall consent to
the making of such payments directly to the Holders, to pay to the Trustee any
amount due it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and its counsel, and any other amounts due
the Trustee under Section 8.7.

      

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

      

      FIRST: to
the Trustee, Registrar, Conversion Agent and Paying Agent for amounts due under
Section 8.7;

      

      SECOND:
to Holders for amounts due and unpaid on the Notes for the principal amount,
Redemption Price, Purchase Price, Fundamental Change Purchase Price or interest,
if any (including Liquidated Damages and Additional Interest, if any), as the
case may be, ratably, without preference or priority of any kind, according to
such amounts due and payable on the Notes; and

      

      THIRD:
the balance, if any, to the Company.

      

      The
Trustee may fix a record date and payment date for any payment to Holders
pursuant to this Section 7.10. At least 15 days before such record date, the
Company shall mail to each Holder and the Trustee a notice that states the
record date, the payment date and the amount to be paid.

      

      SECTION
7.11. Undertaking for
Costs. In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees and expenses, against any party litigant in the suit, having due
regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 7.11 does not apply to a suit by the Trustee, a suit by a
Holder pursuant to Section 7.7 or a suit by Holders of more than 10% in
aggregate principal amount of the Notes at the time outstanding.

      

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

      
        
           

        

        
          54

          
            

          

        

        
           

        

      

      

      SECTION
7.13. Additional
Interest. Notwithstanding any other provision of this Indenture, at the
election of the Company, for the first 180 days after the occurrence of an Event
of Default specified in Section 7.1(a)(4) relating to any failure by the Company
to comply with the requirements of Section 314(a)(1) of the TIA, the sole remedy
for such an Event of Default shall consist exclusively of the right to receive
additional interest on the Notes at an annual rate equal to 0.50% of the
principal amount (“Additional
Interest”) of the Notes. In the event that the Company does not elect to
pay the Additional Interest upon an Event of Default in accordance with this
paragraph, the Notes will be subject to acceleration as provided herein. The
Additional Interest will accrue on all outstanding Notes from and including the
date on which an Event of Default relating to a failure to comply with the
requirements of Section 314(a)(1) of the TIA first occurs up to but not
including the 181st day thereafter (or such earlier date on which the Event of
Default relating to such obligations shall have been cured or waived pursuant to
Section 7.4). On such 181st day (or earlier, if such Event of Default is cured
or waived pursuant to Section 7.4 prior to such 181st day), such Additional
Interest will cease to accrue and shall become due and payable and, if such
Event of Default has not been cured or waived pursuant to Section 7.4 prior to
such 181st day, then the Trustee or the holders of not less than 25% in
principal amount of the Notes may declare the principal of and accrued and
unpaid interest (including Liquidated Damages and Additional Interest, if any)
on all such Notes to be due and payable immediately. This provision shall not
affect the rights of Holders in the event of the occurrence of any other Event
of Default. If the Company elects to pay the Additional Interest in accordance
with this paragraph, the Company shall notify, in the manner provided for in
Section 11.2, the Holders and the Trustee of such election at any time on or
before the close of business on the date on which such Event of Default first
occurs. If the Additional Interest is payable under this Section 7.1, the
Company shall deliver to the Trustee an Officers’ Certificate to that effect
stating the date on which the Additional Interest is payable. Unless and until a
Responsible Officer receives at the Corporate Trust Office such a certificate,
the Trustee may assume without inquiry that no Additional Interest is payable.
If the Additional Interest has been paid by the Company directly to the Persons
entitled to such fee, the Company shall deliver to the Trustee an Officers’
Certificate setting forth the particulars of such payment.

VIII TRUSTEE

      

      SECTION
8.1. Duties of
Trustee.

      

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

      

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

      
        
           

        

        
          55

          
            

          

        

        
           

        

      

      

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

      

      (2)   in
the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed
therein, upon certificates, directions, notices or opinions furnished to the
Trustee and conforming to the requirements of the Indenture. However, in the
case of any such certificates, directions, notices or opinions which by any
provisions hereof are specifically required to be furnished to the Trustee, the
Trustee shall examine such certificates and opinions to determine whether or not
they conform to the requirements of this Indenture (but need not confirm or
investigate the accuracy of mathematical calculations or other facts stated
therein).

      

      (c)   The
Trustee may not be relieved from liability for its own negligent action, its
own

      

      negligent

provision of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any financial liability in the performance of any of
its duties hereunder or in the exercise of any of its rights or powers, if it
shall have reasonable grounds to believe that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it.

      

      (h) Every
provision of this Indenture relating to the conduct or affecting the liability
of or affording protection to the Trustee shall be subject to the provisions of
this Section 8.1 and to the provisions of the TIA upon qualification of the
Indenture under the TIA.

      

      (i) The
Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request or direction of any of the Holders
unless such Holders shall have provided to the Trustee security or indemnity
reasonably satisfactory to it against the costs, expenses (including reasonable
attorneys’ fees and expenses) and liabilities that might be incurred by it in
compliance with such request or direction.

      SECTION
8.2. Rights of
Trustee.

      

      (a)   The
Trustee may conclusively rely and shall be protected in acting or refraining
from acting upon any paper or document believed by it to be genuine and to have
been signed or presented by the proper Person or Persons. The Trustee need not
investigate any fact or matter stated in the document.

      

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

      

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

      

      (d)   The
Trustee shall not be liable for any action it takes or omits to take in good
faith which it believes to be authorized or within its rights or powers; provided, however, that the
Trustee’s conduct does not constitute bad faith, willful misconduct or
negligence.

      

      (e)   The
Trustee may consult with counsel of its selection, and the advice or opinion of
such counsel appointed with due care with respect to legal matters relating to
this Indenture and the Notes shall be full and complete authorization and
protection from liability in respect to any action taken, omitted or suffered by
it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

      

      (f)   The
Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, notice,
request, direction, consent, order, bond 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 at reasonable times, in a reasonable
manner and upon reasonable advance notice, personally or by agent or attorney at
the sole cost of the Company and shall incur no liability or additional
liability of any kind by reason of such inquiry or investigation.

      

      (g)   The
Trustee shall not be deemed to have knowledge of any Default or Event of Default
except, (i) during any period it is serving as Registrar and Paying Agent for
the Notes, any Event of Default occurring pursuant to Sections 7.1(1), 7.1(2),
7.1(4) or 7.1(5) or (ii) any Default or Event of Default of which a Responsible
Officer shall have received written notification or obtained actual knowledge.
The term “actual knowledge” shall mean the actual fact or statement of knowing
by a Responsible Officer without independent investigation with respect
thereto.

      

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

      (i)  
In no event shall the Trustee be responsible or liable for special, indirect, or
consequential loss or damage of any kind whatsoever (including, but not limited
to, loss of profit) irrespective of whether the Trustee has been advised of the
likelihood of such loss or damage and regardless of the form of
action.

      

      (j)  
The rights, privileges, protections, immunities and benefits given to the
Trustee, including its right to be indemnified, are extended to, and shall be
enforceable by, the Trustee in each of its capacities hereunder, and each agent,
custodian and other Person employed to act hereunder.

      

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

      

      SECTION
8.3. Individual Rights
of Trustee. The Trustee in its individual or any other capacity may
become the owner or pledgee of Notes and may otherwise deal with the Company or
its Affiliates with the same rights it would have if it were not Trustee. Any
Paying Agent, Conversion Agent, Registrar, co-registrar or co-paying agent may
do the same with like rights. However, the Trustee must comply with Sections
8.10 and 8.11. In addition, the Trustee shall be permitted to engage in
transactions with the Company; provided, however, that if the Trustee
acquires any conflicting interest (as such term is defined in Section 310(b) of
the TIA) the Trustee must (i) eliminate such conflict within 90 days of
acquiring such conflicting interest, (ii) apply to the SEC for permission to
continue acting as Trustee or (iii) resign as Trustee hereunder.

      

      SECTION
8.4. Trustee’s
Disclaimer. The Trustee shall not be responsible for and makes no
representation as to the validity or adequacy of this Indenture or the Notes, it
shall not be accountable for the Company’s use of the Notes or the proceeds from
the Notes, and it shall not be responsible for any statement of the Company in
this Indenture or in any document issued or offering circular (or similar
document) used in connection with the sale of the Notes or in the Notes other
than the Trustee’s certificate of authentication or for the use or application
of any funds received by any Paying Agent other than the Trustee.

      

      SECTION
8.5. Notice of
Defaults. If a Default or Event of Default occurs and is continuing and
if a Responsible Officer has actual knowledge thereof, the Trustee shall mail to
each Holder notice of the Default or Event of Default within 90 days after it
occurs unless such Default or Event of Default has been cured or waived. Except
in the case of a Default or Event of Default in payment of principal of, or
interest on any Note (including payments pursuant to the required repurchase
provisions of such Note, if any), the Trustee may withhold the notice if and so
long as its board of directors, a committee of its board of directors or a
committee of its Responsible Officers and/or a Responsible Officer in good faith
determines that withholding the notice is in the interests of registered
Holders.

      
        
           

        

        
          58

          
            

          

        

        
           

        

      

      

      SECTION
8.6. Reports by
Trustee to Holders. As promptly as practicable after each December 31
beginning with the December 31 following the date of this Indenture, and in any
event prior to March 31 in each year thereafter, the Trustee shall mail to each
Holder a brief report dated as of such December 31 that complies with TIA Sec.
313(a) upon qualification of the Indenture under the TIA, if and to the extent
such report may be required by the TIA. The Trustee also shall comply with TIA
Sec. 313(b) upon qualification of the Indenture under the TIA. The Trustee shall
also transmit by mail all reports required by TIA Sec. 313(c) upon qualification
of the Indenture under the TIA.

      

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

      

      SECTION
8.7. Compensation and
Indemnity The Company covenants and agrees: (a) to pay to the Trustee,
the Registrar, the Conversion Agent and the Paying Agent from time to time, and
the Trustee, the Registrar, the Conversion Agent or the Paying Agent shall be
entitled to such compensation for all services rendered by it hereunder as shall
be agreed by the Company and the Trustee, the Registrar, the Conversion Agent or
the Paying Agent in writing (which shall not be limited by any provision of law
in regard to the compensation of a trustee of an express trust); (b) to
reimburse the Trustee, the Registrar, the Conversion Agent and the Paying Agent
and each predecessor Trustee upon its request for all reasonable expenses, fees,
disbursements and advances incurred or made by or on behalf of it in accordance
with any of the provisions of this Indenture (including the reasonable
compensation, fees, and the expenses and disbursements of its counsel and of all
agents and other Persons not regularly in its employ), except any such expense,
disbursement or advance as may arise from its negligence or bad faith; and (c)
to indemnify the Trustee, the Registrar, the Conversion Agent and the Paying
Agent and each predecessor Trustee for, and to hold it harmless against, any
loss, liability, damage, claim or expense, including taxes, if any (other than
taxes based upon, determined by or measured by the income of the Trustee, the
Registrar, the Conversion Agent or the Paying Agent), incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this Indenture or the trusts hereunder and its
duties hereunder, including enforcement of this Section 8.7. The obligations of
the Company under this Section 8.7 to compensate and indemnify the Trustee, the
Registrar, the Conversion Agent and the Paying Agent and each predecessor
Trustee and to pay or reimburse the Trustee, the Registrar, the Conversion Agent
and the Paying Agent and each predecessor Trustee for expenses, fees,
disbursements and advances shall constitute an additional obligation hereunder
and shall survive the satisfaction and discharge of this Indenture, the
resignation or removal of the Trustee, the Registrar, the Conversion Agent or
the Paying Agent or the termination of this Indenture. To secure the obligations
of the Company to the Trustee, the Registrar, the Conversion Agent and the
Paying Agent under this Section 8.7, the Trustee, the Registrar, the Conversion
Agent and the Paying Agent shall have a prior Lien upon all property and funds
held or collected by the Trustee or the Paying Agent as such, except funds and
property paid by the Company and held in trust for the benefit of the Holders of
particular Notes. When the Trustee, the Registrar, the Conversion Agent or the
Paying Agent incurs expenses or renders services after an Event of Default
specified in Section 7.1(9) or (10) occurs, such expenses and compensation for
services are intended to constitute expenses of administration under the
Bankruptcy Reform Act of 1978 or any successor statute.

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

      

      (1)   the
Trustee fails to comply with Section 8.10;

      

      (2)   the
Trustee is adjudged bankrupt or insolvent;

      

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

      

      (4)   the
Trustee otherwise becomes incapable of acting.

      

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

      

      A
successor Trustee shall deliver a written acceptance of its appointment to the
retiring Trustee and to the Company. Thereupon the resignation or removal of the
retiring Trustee shall become effective, and the successor Trustee shall have
all the rights, powers and duties of the Trustee under this Indenture. The
successor Trustee shall mail a notice of its succession to Holders. The retiring
Trustee shall promptly transfer all property held by it as Trustee to the
successor Trustee upon payment of any fees and expenses due and owing to
it.

      

      If the
Company has not appointed a successor Trustee within 60 days after the retiring
Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in
principal amount of the Notes may petition, at the expense of the Company, any
court of competent jurisdiction for the appointment of a successor
Trustee.

      

      If the
Trustee fails to comply with Section 8.10, unless the Trustee’s duty to resign
is stayed as provided in TIA Sec. 310(b), any Holder who has been a bona fide
holder of the Notes for six months may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

      

      Notwithstanding
the replacement of the Trustee pursuant to this Section 8.8, the Company’s
obligations under Section 8.7 shall continue for the benefit of the retiring
Trustee.

      

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

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

      

      SECTION
8.10. Eligibility;
Disqualification. There shall at all times be a Trustee hereunder which
shall be eligible to act as Trustee under Trust Indenture Act Sections 310(a)(1)
and (2) and which shall have a combined capital and surplus of at least
$50,000,000, and have a Corporate Trust Office in the Borough of Manhattan in
The City of New York, State of New York. If such corporation publishes reports
of condition at least annually, pursuant to law or to the requirements of any
federal, state, territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation 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, the Trustee shall resign immediately in the manner
and with the effect hereinafter specified in this Article.

      

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

sufficient to pay and discharge all amounts due and owing on all outstanding
Notes (other than Notes replaced pursuant to Section 2.7) and if in either case
the Company pays all other sums payable hereunder by the Company, then this
Indenture shall, subject to Section 2.7, cease to be of further effect; provided, however,
notwithstanding the foregoing, the Company shall not discharge its obligations
with respect to the conversion and delivery of shares of the Company’s Common
Stock, if any, in connection therewith until such time as all payment and
delivery of shares of the Company’s Common Stock has been made. The Trustee
shall acknowledge satisfaction and discharge of this Indenture with respect to
the Notes on demand of the Company accompanied by an Officers’ Certificate and
an Opinion of Counsel and at the cost and expense of the

Trust Indenture Act. Every supplemental indenture or amendment to this
Indenture or the Notes shall comply with the TIA as then in effect upon
qualification of the Indenture under the TIA.

      

      SECTION
10.6. Reference in
Notes to Supplemental Indentures. Notes authenticated and delivered after
the execution of any supplemental indenture pursuant to this Article may, and
shall if required by the Trustee, bear a notation in a form approved by the
Trustee as to any matter provided for in such supplemental indenture. If the
Company shall so determine, new Notes so modified as to conform, in the opinion
of the Trustee and the Board of Directors of the Company, to any such
supplemental indenture may be prepared and executed by the Company and
authenticated and delivered by the Trustee, at the expense of the Company, upon
a Company Order in exchange for Outstanding Notes.

      

      SECTION
10.7. Revocation and
Effect of Consents and Waivers. A consent to an amendment or a waiver by
a Holder of a Note shall bind the Holder and every subsequent Holder of that
Note or portion of the Note that evidences the same debt as the consenting
Holder’s Note, even if notation of the consent or waiver is not made on the
Note. However, any such Holder or subsequent Holder may revoke the consent or
waiver as to such Holder’s Note or portion of the Note if the Trustee receives
the notice of revocation before the date the amendment or waiver becomes
effective. After an amendment or waiver becomes effective, it shall bind every
Holder. An amendment or waiver made pursuant to Section 10.2 shall become
effective upon receipt by the Trustee of the requisite number of written
consents.

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

      

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

Certificate or such other certificates of Officer(s) as it may deem appropriate
and on certificates of public officials.

      

      SECTION
11.6. When Notes
Disregarded. In determining whether the Holders of the required principal
amount of Notes have concurred in any direction, waiver or consent, Notes 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, except that, for the purpose of
determining whether the Trustee shall be protected in relying on any such
direction, waiver or consent, only Notes which a Responsible Officer of the

the foregoing, only Notes outstanding at the time shall be considered in any
such determination.

      

      SECTION

interest on any Note and no recourse under or upon any obligation, covenant,
agreement of the Company or of a guarantor in this Indenture, the Notes, or in
any supplemental indenture, or because of the creation of any Indebtedness
represented thereby, shall be had against any stockholder, employee, officer or
director of the Company or of any successor corporation or entity, whether by
virtue of any constitution, statute or rule of law, or by the enforcement of any
assessment or penalty or otherwise, it being understood that, to the extent

representations as to the validity or sufficiency of this Indenture or of the

      1.875%
Convertible Senior Notes due 2028

      

      Capitalized
terms used herein have the meanings assigned to them in the Indenture referred
to below unless otherwise indicated.

      

      (1)  Interest. Stillwater Mining
Company, a Delaware corporation (the “Company”), promises to pay
interest on the principal amount of this Note at 1.875% per annum from March 12,
2008 until Maturity. The Company will pay interest, if any, semi-annually in
arrears on March 15 and September 15 of each year (subject to limited exceptions
if the Note is converted or purchased prior to such date), or if any such day is
not a Business Day, on the immediately following Business Day (each, an “Interest Payment Date”).
Interest on the Notes will accrue from the most recent date on which interest
has been paid or, if no interest has been paid, from March 12, 2008; provided that if there is no
existing Default in the payment of interest, and if this Note is authenticated
between a Record Date referred to on the face hereof and the next succeeding
Interest Payment Date, interest shall accrue from such next succeeding Interest
Payment Date; provided,
further, that the first Interest Payment Date shall be September 15,
2008. The Company will pay interest on overdue principal from time to time on
demand at the rate then in effect to the extent lawful; it will pay interest on
overdue installments of interest, if any (without regard to any applicable grace
periods), from time to time on demand at the same rate to the extent lawful.
Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

      

      (2)  Method of payment. The Company
will pay interest on the Notes, if any, to the Persons who are registered
Holders of Notes at the close of business on the March 1 or September 1 next
preceding the Interest Payment Date (each a “Regular Record Date”), even if
such Notes are canceled after such record date and on or before such Interest
Payment Date. The Notes will be payable as to principal, if any, and interest at
the office or agency of the Company maintained for such purpose within or
without the City and State of New York, or, at the option of the Company,
payment of interest, if any, may be made by check mailed to the Holders at their
addresses set forth in the register of Holders; provided that payment by wire
transfer of immediately available funds will be required with respect to
principal of and interest, if any, on, all Global Notes and all other Notes with
an aggregate principal amount in excess of $2 million for which the Holders have
provided wire transfer instructions at least 10 Business Days prior to the
Interest Payment Date to the Company or the Paying Agent. Such payment will be
in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts.

      

      (3)  Trustee, Paying Agent, Registrar and
Conversion Agent. Initially, Law Debenture Trustee Company of New York
will act as Trustee under the Indenture and Deutsche Bank Trust Company Americas
will act as Paying Agent, Registrar and Conversion Agent. The Company may change
any Paying Agent, Registrar or Conversion Agent without notice to any Holder.
The Company or any of its Subsidiaries may act in any such
capacity.

      

      (4)  Indenture. The Company issued
the Notes under the Indenture dated as of March 12, 2008 (the “Indenture”) between the
Company, the Trustee and Deutsche Bank Trust Company Americas. The terms of the
Notes include those stated in the Indenture and those made part of the Indenture
by reference to the TIA upon qualification of the Indenture under the TIA. The
Notes are subject to all such terms, and Holders are referred to the Indenture
and the TIA for a statement of such terms. To the extent any provision of this
Note conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling. The Notes are senior, unsecured
obligations of the Company.

      
        
           

        

        
          A-4

          
            

          

        

        
           

        

      

      

      (5)  Denominations, transfer,
exchange. The Notes are in registered form without coupons in
denominations of $1,000 and integral multiples of $1,000. The transfer of Notes
may be registered and Notes may be exchanged as provided in the Indenture. The
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and the Company may require a
Holder to pay any taxes and fees required by law or permitted by the Indenture.
The Company need not exchange or register the transfer of any Note or portion of
a Note selected for conversion or repurchase, except for the unconverted or
unrepurchased portion of any Note being converted or repurchased in part. Also,
the Company need not exchange or register the transfer of any Notes during the
period between a Regular Record Date and the corresponding Interest Payment
Date.

      

      (6)  Persons deemed owners. The
registered Holder of a Note may be treated as its owner for all
purposes.

      

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

      

      (8)  Events of default. In case an
Event of Default, as defined in the Indenture, shall have occurred and be
continuing, the principal and interest (including Liquidated Damages and
Additional Interest, if any) on all Notes may be declared, by either the Trustee
or Noteholders of not less than 25% in aggregate principal amount of Notes then
outstanding, and upon said declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions and certain exceptions set
forth in the Indenture.

      

      (9)  Trustee dealings with Company.
The Trustee, in its individual or any other capacity, may make loans to, accept
deposits from, and perform services for the Company or its Affiliates, and may
otherwise deal with the Company or its Affiliates, as if it were not the
Trustee.

      

      (10)  No recourse against others. A
director, officer, employee, incorporator or stockholder of the Company, as
such, will not have any liability for any obligations of the Company under the
Notes or the Indenture or for any claim based on, in respect of, or by reason of
such obligations or their creation. Each Holder, by accepting a Note, waives and
releases all such liability to the extent permitted by law. The waiver and
release are part of the consideration for the issuance of the
Notes.

      
        
           

        

        
          A-5

          
            

          

        

        
           

        

      

      

      (11)  Open market purchases. The
Company may, to the extent permitted by applicable law, at any time, and from
time to time, purchase Notes at any price in the open market or
otherwise.

      

      (12)  Authentication. This Note will
not be valid until authenticated by the manual signature of the Trustee or an
authenticating agent.

      

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

      

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

      

      (15)  Governing law. THE INTERNAL
LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THE INDENTURE
AND THIS NOTE.

    (iii)          A
Holder of Registrable Securities, on and after September 13, 2008, that is
either an Affiliate of the Company or the Initial Purchaser,
requests;

    

    the
Company shall use its commercially reasonable efforts to file a registration
statement for the registration of, and the sale on a continuous or delayed basis
by the Holders of, all of the Registrable Securities pursuant to Rule 415 or any
similar rule that may be adopted by the Commission (a “Shelf Registration

(ii) above and (z) by the 60th
day after the date of receipt of notice requesting registration from a
Notice Holder but not before the six-month anniversary of the last date of
original issuance of the Notes, in the case of clause (iii) above, each such
date, an “Effectiveness
Deadline Date.” The Initial Shelf Registration Statement shall be on Form
S-3 or another appropriate form permitting registration of such Registrable

related Prospectus in such a manner as to permit such Holder to deliver such
Prospectus to purchasers of Registrable Securities in accordance with applicable
law. None of the Company’s security holders (other than the Holders of
Registrable Securities) shall have the right to include any of the Company’s
securities in the Shelf Registration Statement.

    

    (b)           The
Company agrees to use its commercially reasonable efforts to keep such Initial
Shelf Registration Statement (or any Subsequent Registration Statement)
continuously effective, subject to Section 3(h), until the earliest of (x) with
respect to a Shelf Registration Statements filed in accordance with Sections
2(a)(i) and 2(a)(ii) only, one year from the last date of original issuance of
the Notes; (y) the date by which all Registrable Securities have been sold
pursuant to the Shelf Registration Statement; and (z) such date as each of the
Registrable Securities covered by the Shelf Registration Statement ceases to be
a Registrable Security (the “Effectiveness Period”). If the
Initial Shelf Registration Statement or any Subsequent Shelf Registration
Statement ceases to be effective for any reason at any time during the
Effectiveness Period, the Company shall use its reasonable best efforts to
obtain the prompt withdrawal of any order suspending the effectiveness thereof,
and in any event shall within thirty NYDOCS01/1162985.5 5 (30) days of such cessation of
effectiveness amend the Shelf Registration Statement in a manner reasonably
expected to obtain the withdrawal of the order suspending the effectiveness
thereof, or file an additional Shelf Registration Statement (a “Subsequent Shelf Registration
Statement”) covering all of the securities that as of the date of such
filing are Registrable Securities. If a Subsequent Shelf Registration Statement
is filed, the Company shall use its commercially reasonable efforts to cause the
Subsequent Shelf Registration Statement to become effective as promptly as is
practicable after such filing.

    (c)           The Company shall supplement and amend
the Shelf Registration Statement if required by the rules, regulations or
instructions applicable to the registration form used by the Company for such
Shelf Registration Statement or as otherwise required by the Securities Act or
as necessary to name a Notice Holder as a selling securityholder pursuant to
Section 2(d) below.

    

    (d)           Each Holder agrees that if such Holder
wishes to sell Registrable Securities pursuant to a Shelf Registration Statement
and related Prospectus, it will do so only in accordance with this Section 2(d),
Section 3(h), and Section 4. Following the date that the Initial Shelf
Registration Statement becomes or is declared effective, each Holder wishing to
sell Registrable Securities pursuant to a Shelf Registration Statement and
related Prospectus agrees to deliver a Notice and Questionnaire to the Company
at least five (5) Business Days prior to any intended distribution of
Registrable Securities under the Shelf Registration Statement. Each Holder who
elects to sell Registrable Securities pursuant to a Shelf Registration Statement
agrees, by submitting a Notice and Questionnaire to the Company, it will be
bound by the terms and conditions of the Notice and Questionnaire and this
Agreement. From and after the date the Initial Shelf Registration Statement
becomes or is declared effective, the Company shall, as promptly as practicable
after the date a Notice and Questionnaire is delivered pursuant to Section 9(c)
hereof, and in any event upon the later of (x) ten (10) Business Days after such
date or (y) ten (10) Business Days after the expiration of any Deferral Period
that is in effect when the Notice and Questionnaire is delivered or that is put
into effect within ten (10) Business Days of such delivery
date:

    

    (i)            
if required by applicable law,
file with the SEC a post-effective amendment to the Shelf Registration Statement
or prepare and, if required by applicable law, file a supplement to the related
Prospectus or a supplement or amendment to any document incorporated therein by
reference or file any other required document so that the Holder delivering such
Notice and Questionnaire is named as a selling securityholder in the Shelf
Registration Statement and the related Prospectus in such a manner as to permit
such Holder to deliver such Prospectus to purchasers of the Registrable
Securities in accordance with applicable law and, if the Company shall file a
post-effective amendment to the Shelf Registration Statement, use its reasonable
best efforts to cause such post-effective amendment to be declared effective
under the Securities Act as promptly as is practicable, but in any event by the
date (the “Amendment
Effectiveness Deadline Date”) that is sixty (60) days after the
date such post-effective amendment is required by this clause to be filed;
and

    

    (ii)          
 provide such Holder copies of any documents filed pursuant to Section
2(d)(i); provided that
if such Notice and Questionnaire is delivered during a Deferral NYDOCS01/1162985.5 6 Period, the Company shall so
inform the Holder delivering such Notice and Questionnaire. The Company shall
notify such Holder as promptly as practicable after the effectiveness under the
Securities Act of any post-effective amendment filed pursuant to Section
2(d)(i). Notwithstanding anything contained herein to the contrary, (i) the
Company shall be under no obligation to name any Holder that is not a Notice
Holder as a selling securityholder in any Registration Statement or related
Prospectus and (ii) the Amendment Effectiveness Deadline Date shall be extended
by up to seven (7) Business Days from the expiration of a Deferral Period (and
the Company shall incur no obligation to pay Liquidated Damages during such
extension or during such Deferral Period) if such Deferral Period shall be in
effect on the Amendment Effectiveness Deadline Date.

    (e)           
If any of the following events
(any such event a “Registration
Default”) shall occur,
then the Company shall pay additional interest (“Liquidated
Damages”) as liquidated
damages and not as a penalty to Holders in respect of the Notes as
follows:

    

    (i)           
if on October 9, 2008, Registrable Securities are held by any Person other than
an Affiliate of the Company and the Shelf Registration Statement has not been
filed with and declared effective by the Commission by such date (other than
pursuant to Section 3(h) hereof), then, commencing on such date, Liquidated
Damages shall accrue on the principal amount of the outstanding Notes that are
Registrable Securities at a rate of 0.50% per annum;

    

    (ii)           at any time after October 9, 2008 the
conditions set forth in paragraph (c)(1) of Rule 144 are not satisfied with
respect to the Securities and the Shelf Registration Statement has not been
filed with and declared effective by the Commission at or prior to the later of
(x) the six month anniversary of the last date of original issuance of the Notes
and (y) the time that such conditions cease to be satisfied (other than pursuant
to Section 3(h) hereof), then, commencing on such later date, Liquidated Damages
shall accrue on the principal amount of the outstanding Notes that are
Registrable Securities at a rate of 0.50% per annum;

    

    (iii)           if
the Shelf Registration Statement has become or been declared effective but such
Shelf Registration Statement ceases to be effective or the prospectus contained
therein ceases to be usable in connection with the resales of Registrable
Securities at any time during the Effectiveness Period (other than pursuant to
Section 3(h) hereof), then, commencing on the day such Shelf Registration
Statement ceases to be effective, Liquidated Damages shall accrue on the
principal amount of the outstanding Notes that are Registrable Securities at a
rate of 0.50% per annum following such date on which the Shelf Registration
Statement ceases to be effective;

    

    (iv)           if the aggregate duration of Deferral
Periods in any period exceeds the number of days permitted in respect of such
period pursuant to Section 3(h) hereof, then, commencing on the day the
aggregate duration of Deferral Periods in any period exceeds the number of days
permitted in respect of such period, Liquidated Damages shall accrue on the
principal amount of the outstanding Notes that are Registrable Securities at a
rate of 0.50% per annum; NYDOCS01/1162985.5

    (v)           by
March 16, 2009, (1) the Company has failed either to remove the restrictive
legends from the Notes (except for any restrictive legends with respect to Notes
held by Affiliates) relating to the Securities Act, or (2) a Shelf Registration
Statement has not become or been declared effective, or if such Shelf
Registration Statement ceases to be effective, then, Liquidated Damages shall
accrue on the principal amount of the outstanding Notes at a rate of 0.50% per
annum;

    

    provided, however, that the Liquidated
Damages rate on the Notes shall not exceed in the aggregate 0.50% per annum;
provided further,
however, that Liquidated Damages on the Notes that are Registrable Securities as
a result of clauses (i) through (iv) above, shall cease to accrue upon the
earlier of (x) March 12, 2009 and (y)(1) the filing and effectiveness of the
Shelf Registration Statement (in the case of clauses (i) and (ii) above), (2)
the effectiveness of the Shelf Registration Statement which had ceased to remain
effective (in the case of clause (iii) above) and (3) the termination of the
Deferral Period that caused the limit on the aggregate duration of Deferral
Periods in a period set forth in Section 3(h) to be exceeded (in the case of
clause (iv) above). Liquidated Damages on the Notes, if any, will be payable in
arrears in cash on March 15 and September 15 of each year (the “Liquidated Damages Payment
Date”) to holders of record of outstanding Notes that are Registrable
Securities at the close of business on March 1 or September 1 (whether or not a
Business Day), as the case may be, immediately preceding the relevant interest
payment date; provided
that any Liquidated Damages Amount accrued with respect to any Note or
portion thereof redeemed by the Company on a redemption date or converted into
Underlying Common Stock on a conversion date prior to the Registration Default,
shall, in any such event, be paid instead to the Holder who submitted such Note
or portion thereof for redemption or conversion on the applicable redemption
date or settlement date with respect to such conversion, as the case may be, on
such date (such date being the day the a Holder receives the consideration due
to such Holder upon conversion). The Trustee shall be entitled, on behalf of
Holders of Notes or Underlying Common Stock, to seek any available remedy for
the enforcement of this Agreement, including for the payment of such Liquidated
Damages. Following the cure of all Registration Defaults requiring the payment
of Liquidated Damages to the Holders of Notes that are Registrable Securities
pursuant to this Section 2(e), the accrual of Liquidated Damages will cease
(without in any way limiting the effect of any subsequent Registration Default
requiring the payment of Liquidated Damages). Liquidated Damages on the Notes,
if any, will accrue beginning on the date provided for in clauses 2(e)(i)
through (v) above, as applicable, to, but excluding, the date on which all
registration Defaults have been cured. Notwithstanding the foregoing, the
parties agree that the sole damages payable for a violation of the terms of this
Agreement with respect to which liquidated damages are expressly provided shall
be such liquidated damages. Nothing shall preclude any Holder from pursuing or
obtaining specific performance or other equitable relief with respect to this
Agreement in accordance with applicable law.

     

    (f)           
The Company shall notify the
Trustee promptly upon the happening of each and every Registration Default. The
Trustee shall be entitled, on behalf of Holders, to seek any available remedy
for the enforcement of this Agreement, including for the payment of any
Liquidated Damages if any become due. Notwithstanding the foregoing, the parties
agree that the sole monetary damages payable for a violation of the terms of
this Agreement with respect to which additional monetary amounts are expressly
provided shall be as set forth in this Section 2(e). Nothing shall preclude a
Notice Holder or Holder from pursuing or obtaining specific performance or other
equitable relief with respect to this Agreement.

    SECTION
3. Registration
Procedures. In connection
with the registration obligations of the Company under Section 2 hereof, during
the Effectiveness Period, the Company shall:

    

    (a)           Prepare and file with the SEC a Shelf
Registration Statement or Shelf Registration Statements on any appropriate form
under the Securities Act available for the sale of the Registrable Securities by
the Holders thereof in accordance with the intended method or methods of
distribution thereof, and use its commercially reasonable efforts to cause each
such Shelf Registration Statement to become effective and remain effective as
provided herein; provided
that before filing any
Shelf Registration Statement or Prospectus or any amendments or supplements
thereto with the SEC (but excluding reports filed with the SEC under the
Exchange Act), furnish to the Initial Purchaser and the Special Counsel, if any,
copies of all such documents proposed to be filed at least three (3) Business
Days prior to the filing of such Shelf Registration Statement or amendment
thereto or Prospectus or supplement thereto, or as such shorter period as may be
agreed upon by the Initial Purchaser and the Special
Counsel.

    

    (b)           Subject to Section 3(h), prepare and
file with the SEC such amendments and post-effective amendments to each Shelf
Registration Statement as may be necessary to keep such Shelf Registration
Statement continuously effective for the applicable period specified in Section
2(a); cause the related Prospectus to be supplemented by any required prospectus
supplement, and as so supplemented to be filed pursuant to Rule 424 (or any
similar provisions then in force) under the Securities Act; and use its
reasonable best efforts to comply with the provisions of the Securities Act
applicable to it with respect to the disposition of all securities covered by
such Shelf Registration Statement during the Effectiveness Period in accordance
with the intended methods of disposition by the sellers thereof set forth in
such Shelf Registration Statement as so amended or such Prospectus as so
supplemented.

    

    (c)           As promptly as practicable give notice
to the Notice Holders, the Initial Purchaser and the Special Counsel, if any (i)
when any Prospectus, prospectus supplement, Registration Statement or
post-effective amendment to a Registration Statement has been filed with the SEC
and, with respect to a Shelf Registration Statement or any post-effective
amendment, when the same has been declared effective, (ii) of any request,
following the effectiveness of the Initial Shelf Registration Statement under
the Securities Act, by the SEC or any other federal or state governmental
authority for amendments or supplements to any Shelf Registration Statement or
related Prospectus or for additional information relating to the Shelf
Registration Statement, (iii) of the issuance by the SEC or any other federal or
state governmental authority of any stop order suspending the effectiveness of
any Shelf Registration Statement or the initiation or threatening of any
proceedings for that purpose, (iv) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purpose, (v) of the occurrence of, but not the nature of or details concerning,
a Material Event (as defined below) and (vi) of the determination by the Company
that a post-effective amendment to a Shelf Registration Statement will be filed
with the SEC, which notice may, at the discretion of the Company (or as required
NYDOCS01/1162985.5
9 pursuant to Section
3(h)), state that it constitutes a Deferral Notice, in which event the
provisions of Section 3(h) shall apply.

    
      
         

      

      
        8

        
          

        

      

      
         

      

    

     

    (d)           Use its reasonable best efforts to
obtain the withdrawal of any order suspending the effectiveness of a Shelf
Registration Statement or the lifting of any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction in which they have been qualified for sale, in either case at
the earliest possible moment, and provide immediate notice to each Notice Holder
and the Initial Purchaser of the withdrawal of any such
order.

    

    (e)           As promptly as practicable furnish to
each Notice Holder, the Special Counsel, if any, and the Initial Purchaser, upon
request and without charge, at least one (1) conformed copy of the Registration
Statement and any amendment thereto, including exhibits and, if requested, all
documents incorporated or deemed to be incorporated therein by
reference.

    

    (f)           
Deliver to each Notice Holder, the Special Counsel, if any, and the Initial
Purchaser, in connection with any sale of Registrable Securities pursuant to a
Registration Statement, without charge, as many copies of the Prospectus
relating to such Shelf Registrable Securities (including each preliminary
prospectus) and any amendment or supplement thereto as such persons may
reasonably request; and the Company hereby consents (except during such periods
that a Deferral Notice is outstanding and has not been revoked) to the use of
such Prospectus or each amendment or supplement thereto by each Notice Holder in
connection with any offering and sale of the Registrable Securities covered by
such Prospectus or any amendment or supplement thereto in the manner set forth
therein.

    

    (g)           Prior to any public offering of the
Registrable Securities pursuant to a Shelf Registration Statement, use its
reasonable best efforts to register or qualify or cooperate with the Notice
Holders and the Special Counsel, if any, in connection with the registration or
qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as any Notice Holder reasonably
requests in writing (which request may be included in the Notice and
Questionnaire); prior to any public offering of the Registrable Securities
pursuant to the Shelf Registration Statement, use its reasonable best efforts to
keep each such registration or qualification (or exemption therefrom) effective
during the Effectiveness Period in connection with such Notice Holder’s offer
and sale of Registrable Securities pursuant to such registration or
qualification (or exemption therefrom) and do any and all other acts or things
reasonably necessary or advisable to enable the disposition in such
jurisdictions of such Registrable Securities in the manner set forth in the
relevant Shelf Registration Statement and the related Prospectus; provided
that the Company will not
be required to (i) qualify as a foreign corporation or as a dealer in securities
in any jurisdiction where it would not otherwise be required to qualify but for
this Agreement or (ii) take any action that would subject it to general service
of process or to taxation in any such jurisdiction where it is not then so
subject.

    

    (h)           Upon
(A) the issuance by the SEC of a stop order suspending the effectiveness of any
Shelf Registration Statement or the initiation of proceedings with respect to
any Shelf Registration Statement under Section 8(d) or 8(e) of the Securities
Act, (B) the occurrence of any event or the existence of any fact (a “Material Event”) as a result
of which NYDOCS01/1162985.5
10 any Shelf
Registration Statement shall contain any untrue statement of a material fact or
omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, or any Prospectus shall contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading, or (C) the
occurrence or existence of any pending corporate development that, in the
reasonable discretion of the Company, makes it appropriate to suspend the
availability of any Shelf Registration Statement and the related
Prospectus:

    
      
         

      

      
        9

        
          

        

      

      
         

      

    

     

    (i)           in the case of clause (B) above,
subject to the next sentence, as promptly as practicable prepare and file, if
necessary pursuant to applicable law, a post-effective amendment to such Shelf
Registration Statement or a supplement to the related Prospectus or any document
incorporated therein by reference or file any other required document that would
be incorporated by reference into such Shelf Registration Statement and
Prospectus so that such Shelf Registration Statement does not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading, and
such Prospectus does not contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, as thereafter delivered to the purchasers of the
Registrable Securities being sold thereunder, and, in the case of a
posteffective amendment to a Shelf Registration Statement, subject to the next
sentence, use its reasonable best efforts to cause it to be declared effective
as promptly as is practicable, and

    

    (ii)           give
notice to the Notice Holders and the Special Counsel, if any, that the
availability of the Shelf Registration Statement is suspended (a “Deferral Notice”) and, upon
receipt of any Deferral Notice, each Notice Holder agrees not to sell any
Registrable Securities pursuant to the Shelf Registration Statement until such
Notice Holder’s receipt of copies of the supplemented or amended Prospectus
provided for in clause (i) above, or until it is advised in writing by the
Company that the Prospectus may be used, and has received copies of any
additional or supplemental filings that are incorporated or deemed incorporated
by reference in such Prospectus.

    

    The
Company will use its reasonable best efforts to ensure that the use of the
Prospectus may be resumed (x) in the case of clause (A) above, as promptly as is
practicable, (y) in the case of clause (B) above, as soon as, in the sole
judgment of the Company, public disclosure of such Material Event would not be
prejudicial to or contrary to the interests of the Company or, if necessary to
avoid unreasonable burden or expense, as soon as practicable thereafter, and (z)
in the case of clause (C) above, as soon as, in the reasonable discretion of the
Company, such suspension is no longer appropriate. The Company shall be entitled
to exercise its right under this Section 3(h) to suspend the availability of any
Shelf Registration Statement or any Prospectus, without incurring or accruing
any obligation to pay liquidated damages pursuant to Section 2(e) (the “Deferral Period”); provided that the aggregate
duration of any Deferral Periods shall not exceed 45 days in any three month
period or 120 days in any twelve (12) month period.

    
      
         

      

      
        10

        
          

        

      

      
         

      

    

     

    (i)           If
reasonably requested in writing in connection with a disposition of Registrable
Securities pursuant to a Shelf Registration Statement, make reasonably available
for inspection during normal business hours by a representative for the Notice
Holders of such Registrable Securities, any broker-dealers, underwriters,
attorneys and accountants retained by such Notice Holders, and any attorneys or
other agents retained by a broker-dealer or underwriter engaged by such Notice
Holders, all relevant financial and other records and pertinent corporate
documents and properties of the Company and its subsidiaries, and cause the
appropriate officers, directors and employees of the Company and its
subsidiaries to make reasonably available for inspection during normal business
hours on reasonable notice all relevant information reasonably requested by such
representative for the Notice Holders, or any such broker-dealers, underwriters,
attorneys or accountants in connection with such disposition, in each case as is
customary for similar “due diligence” examinations; provided that such persons
shall first agree in writing with the Company that any information that is
reasonably designated by the Company as confidential at the time of delivery of
such information shall be kept confidential by such persons and shall be used
solely for the purposes of exercising rights under this Agreement, unless (i)
disclosure of such information is required by court or administrative order or
is necessary to respond to inquiries of regulatory authorities, (ii) disclosure
of such information is required by law (including any disclosure requirements
pursuant to federal securities laws in connection with the filing of any Shelf
Registration Statement or the use of any Prospectus referred to in this
Agreement), (iii) such information becomes generally available to the public
other than as a result of a disclosure or failure to safeguard by any such
person or (iv) such information becomes available to any such person from a
source other than the Company and such source is not bound by a confidentiality
agreement; and provided
further that the foregoing inspection and information gathering shall, to
the greatest extent possible, be coordinated on behalf of all the Notice Holders
and the other parties entitled thereto by Special Counsel, if any, or another
representative selected by a majority of Registrable Securities being sold by
such Holders pursuant to such Shelf Registration Statement. Any person legally
compelled or required by administrative or court order or by a regulatory
authority to disclose any such confidential information made available for
inspection shall provide the Company with prompt prior written notice of such
requirement so that the Company may seek a protective order or other appropriate
remedy.

     

    (j)           Comply with all applicable rules and
regulations of the SEC and make generally available to its securityholders
earning statements (which need not be audited) satisfying the provisions of
Section 11(a) of the Securities Act and Rule 158 thereunder (or any similar rule
promulgated under the Securities Act) for a 12-month period commencing on the
first day of the first fiscal quarter of the Company commencing after the
effective date of a Shelf Registration Statement, which statements shall be made
available no later than 45 days after the end of the 12-month period or 90 days
if the 12-month period coincides with the fiscal year of the
Company.

    

    (k)           Cooperate
with each Notice Holder to facilitate the timely preparation and delivery of
certificates representing Registrable Securities sold or to be sold pursuant to
a Shelf Registration Statement, which certificates shall not bear any
restrictive legends, and cause such Registrable Securities to be in such
denominations as are permitted by the Indenture and registered in such names as
such Notice Holder may request in writing at least two (2) Business Days prior
to any sale of such Registrable Securities.

    
      
         

      

      
        11

        
          

        

      

      
         

      

    

    

    (l)           Provide a CUSIP number for all
Registrable Securities covered by each Shelf Registration Statement not later
than the effective date of such Shelf Registration Statement and, if requested,
provide the Trustee and the transfer agent for the Common Stock with printed
certificates for the Registrable Securities that are in a form eligible for
deposit with The Depository Trust Company.

    

    (m)           Cooperate
and assist in any filings required to be made with the Financial Industry
Regulatory Authority (“FINRA”).

    

    (n)           In the case of a Shelf Registration
Statement involving an underwritten offering, the Company shall enter into such
customary agreements (including, if requested, an underwriting agreement in
reasonably customary form) and take all such other action, if any, as Holders of
a majority of the Registrable Securities being sold or any managing underwriters
reasonably shall request in order to facilitate any disposition of Notes and
Underlying Common Stock pursuant to such Shelf Registration Statement,
including, without limitation, (i) using its reasonable best efforts to cause
its counsel to deliver an opinion or opinions in reasonably customary form, (ii)
using its reasonable best efforts to cause its officers to execute and deliver
all customary documents and certificates and (iii) using its reasonable best
efforts to cause its independent public accountants to provide a comfort letter
or letters in reasonably customary form; provided
that with respect to
clause (i), (ii) and (iii), the Company shall be reimbursed by Holders of the
Registrable Securities being sold for the reasonable expenses incurred in
connection with its obligations under this Section 3(n).

    

    (o)           Cause the Indenture to be qualified
under the Trust Indenture Act in a manner prescribed by the Trust Indenture Act
and shall enter into any necessary supplemental indentures in connection
therewith.

    

    (p)           Upon
(i) the filing of the Initial Shelf Registration Statement and (ii) the
effectiveness of the Initial Shelf Registration Statement, announce the same, in
each case by release to Reuters Economic Services and Bloomberg Business
News.

    

    (q)           Enter into such customary agreements
and take such other reasonable and lawful actions in connection therewith
(including those reasonably requested by Holders of a majority of the
Registrable Securities) in order to expedite or facilitate disposition of such
Registrable Securities.

    

    SECTION 4. Holder’s Obligations. Each
Holder agrees, by acquisition of the Registrable Securities, that no Holder
shall be entitled to sell any of such Registrable Securities pursuant to a
Registration Statement or to receive a Prospectus relating thereto unless such
Holder has furnished the Company with a Notice and Questionnaire as required
pursuant to Section 2(d) hereof (including the information required to be
included in such Notice and Questionnaire) and the information set forth in the
next sentence. Each Notice Holder agrees promptly to furnish to the Company all
information required to be disclosed in order to make the information previously
furnished to the Company by such Notice Holder not misleading and any other
information regarding such Notice Holder and the distribution of such
Registrable Securities as the Company may from time to time reasonably request.
Any sale of any Registrable Securities by any Holder shall constitute a
representation and warranty by such  Holder that the
information relating to such Holder and its plan of distribution is as set forth
in the Prospectus delivered by such Holder in connection with such disposition,
that such Prospectus does not as of the time of such sale contain any untrue
statement of a material fact relating to or provided by such Holder or its plan
of distribution and that such Prospectus does not as of the time of such sale
omit to state any material fact relating to or provided by such Holder or its
plan of distribution necessary to make the statements in such Prospectus, in the
light of the circumstances under which they were made, not misleading. Each
Holder further agrees, by acquiring Registrable Securities, that it will not
take any action that would result in the Company being required to file with the
SEC under Rule 433(d) a free writing prospectus (as defined in Rule 405 under
the Securities Act) prepared by or on behalf of such Holder that otherwise would
not be required to be filed by the Company thereunder but for the action of such
Holder.

    
      
         

      

      
        12

        
          

        

      

      
         

      

    

     

    SECTION
5. Registration
Expenses. The Company
shall bear all fees and expenses incurred in connection with the performance by
the Company of its obligations under Sections 2 and 3 of this Agreement whether
or not any Shelf Registration Statement becomes or is declared effective. Such
fees and expenses shall include, without limitation, (i) all registration and
filing fees (including, without limitation, fees and expenses (x) with respect
to filings required to be made with FINRA and (y) of compliance with federal and
state securities or Blue Sky laws (including, without limitation, reasonable
fees and disbursements of the Special Counsel, if any, in connection with Blue
Sky qualifications of the Registrable Securities under the laws of such
jurisdictions as Notice Holders of a majority of the Registrable Securities
being sold pursuant to a Shelf Registration Statement may designate up to a
maximum amount of $15,000)), (ii) printing expenses (including, without
limitation, expenses of printing certificates for Registrable Securities in a
form eligible for deposit with The Depository Trust Company), (iii) duplication
expenses relating to copies of any Shelf Registration Statement or Prospectus
delivered to any Holders hereunder, (iv) fees and disbursements of counsel for
the Company in connection with any Shelf Registration Statement, (v) reasonable
fees and disbursements of the Trustee and its counsel and of the registrar and
transfer agent for the Common Stock and (vi) any Securities Act liability
insurance obtained by the Company in its sole discretion. In addition, subject
to Section 3(n), the Company shall pay the internal expenses of the Company
(including, without limitation, all salaries and expenses of officers and
employees performing legal or accounting duties), the expense of any annual
audit, the fees and expenses incurred in connection with the listing by the
Company of the Registrable Securities on any securities exchange on which
similar securities of the Company are then listed and the fees and expenses of
any person, including special experts, retained by the Company. Notwithstanding
the provisions of this Section 5, each seller of Registrable Securities shall
pay selling expenses, including any underwriting discount and commissions, all
registration expenses to the extent required by applicable law and, except as
otherwise provided herein, fees and expenses of counsel to such
seller.

    

    SECTION 6. Indemnification and Contribution by
the Company. Upon the registration of the Registrable Securities pursuant
to Section 2 hereof, the Company shall indemnify and hold harmless each Notice
Holder and each underwriter, selling agent or other securities professional, if
any, which facilitates the disposition of Registrable Securities, and each of
their respective officers and directors and each person who controls such Notice
Holder, underwriter, selling agent or other securities professional within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
(each such person being sometimes referred to as an “Indemnified Person”) against
any losses, claims, damages or liabilities, joint or several, to which such
Indemnified Person may become subject under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or alleged untrue
statement of a material fact contained in any Shelf Registration Statement under
which such Registrable Securities are to be registered under the Securities Act,
or any Prospectus contained therein or furnished by the Company to any
Indemnified Person, or any amendment or supplement thereto, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and the Company hereby agrees to reimburse such Indemnified Person
for any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided,
however, that the Company shall not be liable to any such Indemnified Person in
any such case to the extent that any such loss, claim, damage or liability
arises out of or is based upon an untrue statement or alleged untrue statement
or omission or alleged omission made in such Shelf Registration Statement or
Prospectus, or amendment or supplement, in reliance upon and in conformity with
written information furnished to the Company by such Indemnified Person
expressly for use therein.

    
      
         

      

      
        13

        
          

        

      

      
         

      

    

     

    (b)           Indemnification by
the Notice Holders and any Agents and Underwriters. Each Notice Holder agrees, as a
consequence of the inclusion of any of such Notice Holder’s Registrable
Securities in such Shelf Registration Statement, and each underwriter, selling
agent or other securities professional, if any, which facilitates the
disposition of Registrable Securities shall agree, as a consequence of
facilitating such disposition of Registrable Securities, severally and not
jointly, to (i) indemnify and hold harmless the Company, its directors, officers
who sign any Shelf Registration Statement and each person, if any, who controls
the Company within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act, against any losses, claims, damages or
liabilities to which the Company or such other persons may become subject, under
the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in
such Shelf Registration Statement or Prospectus, or any amendment or supplement,
or arise out of or are based upon the omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Notice Holder, underwriter, selling
agent or other securities professional expressly for use therein, and (ii)
reimburse the Company for any legal or other expenses reasonably incurred by the
Company in connection with investigating or defending any such action or claim
as such expenses are incurred.

    

    (c)           Notices of Claims, Etc.
Promptly after receipt by an indemnified party under subsection (a) or
(b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against an indemnifying party
under this Section 6, notify such indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under the indemnification provisions of or contemplated by
subsection (a) or (b) above. In case any such action shall be brought against
any indemnified party and it shall notify an indemnifying party of the
commencement thereof, such indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party (who shall not be
counsel to the indemnifying party), and, after notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, such indemnifying party shall not be liable to such indemnified party
under this Section 6 for any legal expenses of other counsel or any other
expenses, in each case subsequently incurred by such indemnified party, in
connection with the defense thereof other than reasonable costs of
investigation; provided, however, that an indemnified
party shall have the right to employ its own counsel in any such action, but the
fees, expenses and other charges of such counsel for the indemnified party will
be at the expense of such indemnified party unless (1) the employment of counsel
by the indemnified party has been authorized in writing by the indemnifying
party, (2) the indemnified party has reasonably concluded (based upon advice of
counsel to the indemnified party) that there may be legal defenses available to
it or other indemnified parties that are different from or in addition to those
available to the indemnifying party, (3) a conflict or potential conflict exists
(in which case the indemnifying party will not have the right to direct the
defense of such action on behalf of the indemnified party) or (4) the
indemnifying party has not in fact employed counsel reasonably satisfactory to
the indemnified party to assume the defense of such action within a reasonable
time after receiving notice of the commencement of the action, in each of which
cases the reasonable fees, disbursements and other charges of counsel will be at
the expense of the indemnifying party or parties. It is understood that the
indemnifying party or parties shall not, in connection with any proceeding or
related proceedings in the same jurisdiction, be liable for the reasonable fees,
disbursements and other charges of more than one separate firm of attorneys (in
addition to any local counsel) at any one time for all such indemnified party or
parties. No indemnifying party shall, without the written consent of the
indemnified party, effect the settlement or compromise of, or consent to the
entry of any judgment with respect to, any pending or threatened action or claim
in respect of which indemnification or contribution may be sought hereunder
(whether or not the indemnified party is an actual or potential party to such
action or claim) unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability arising out of
such action or claim and (ii) does not include a statement as to, or an
admission of, fault, culpability or a failure to act, by or on behalf of any
indemnified party.

    (d)           Contribution. If the
indemnification provided for in this Section 6 is unavailable to or insufficient
to hold harmless an indemnified party under subsection (a) or (b) above in
respect of any losses, claims, damages or liabilities (or actions in respect
thereof) referred to therein, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as a result of such losses,
claims, damages or liabilities (or actions in respect thereof) in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party and the indemnified party in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations
including, but not limited to, the timeliness of the notice given as required by
Section 6(c). The relative fault of such indemnifying party and indemnified
party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or omission or alleged
omission to state a material fact relates to information supplied by such
indemnifying party or by such indemnified party, and the parties’ relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 6(d) were determined by
pro rata allocation (even if the Notice Holders or any underwriters, selling
agents or other securities professionals or all of them were treated as one
entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in this Section 6(d).
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
shall be deemed to include any legal or other fees or expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The obligations of the Notice Holders and any underwriters,
selling agents or other securities professionals in this Section 6(d) to
contribute shall be several in proportion to the percentage of principal amount
of Registrable Securities registered or underwritten, as the case may be, by
them and not joint.

    
      
         

      

      
        15

        
          

        

      

      
         

      

    

     

    (e)           Notwithstanding any other provision of
this Section 6, in no event will any (i) Notice Holder be required to undertake
liability to any person under this Section 6 for any amounts in excess of the
dollar amount of the proceeds to be received by such Holder from the sale of
such Holder's Registrable Securities (after deducting any fees, discounts and
commissions applicable thereto) pursuant to any Shelf Registration Statement
under which such Registrable Securities are to be registered under the
Securities Act and (ii) underwriter, selling agent or other securities
professional be required to undertake liability to any person hereunder for any
amounts in excess of the discount, commission or other compensation payable to
such underwriter, selling agent or other securities professional with respect to
the Registrable Securities underwritten by it and distributed to the
public.

    

    (f)           The obligations of the Company under
this Section 6 shall be in addition to any liability which the Company may
otherwise have to any Indemnified Person and the obligations of any Indemnified
Person under this Section 6 shall be in addition to any liability which such
Indemnified Person may otherwise have to the Company. The remedies provided in
this Section 6 are not exclusive and shall not limit any rights or remedies
which may otherwise be available to an indemnified party at law or in
equity.

    

    SECTION 7. Information Requirements. The
Company covenants that, if at any time before the end of the Effectiveness
Period the Company is not subject to the reporting requirements of the Exchange
Act, it will cooperate with any Holder and take such further reasonable action
as any Holder may reasonably request in writing (including, without limitation,
making such reasonable representations as any such Holder may reasonably
request), all to the extent required from time to time to enable such Holder to
sell Registrable Securities without registration under the Securities Act within
the limitation of the exemptions provided by Rule 144 and Rule 144A under the
Securities Act and customarily taken in connection with sales pursuant to such
exemptions. Upon the written request of any Holder, the Company shall deliver to
such Holder a written statement as to whether it has complied with such filing
requirements, unless such a statement has been included in the Company’s most
recent report filed pursuant to Section 13 or Section 15(d) of Exchange Act.
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to
require the Company to register any of its securities (other than the Common
Stock) under any section of the Exchange Act.

    
      
         

      

      
        16

        
          

        

      

      
         

      

    

     

    SECTION
8. Underwritten
Registrations. The Holders
of Registrable Securities covered by a Shelf Registration Statement who desire
to do so may sell such Registrable Securities to an underwriter in an
underwritten offering for reoffering to the public. If any of the Registrable
Securities covered by any Shelf Registration Statement are to be sold in an
underwritten offering, the investment banker or investment bankers and manager
or managers that will administer the offering will be selected by the Holders of
a majority of such Registrable Securities included in such offering, subject to
the consent of the Company (which shall not be unreasonably withheld or
delayed), and such Holders shall be responsible for all underwriting commissions
and discounts and any transfer taxes in connection therewith. No person may
participate in any underwritten registration hereunder unless such person (i)
agrees to sell such person’s Registrable Securities on the basis reasonably
provided in any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements and (ii) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements.

    

    SECTION 9. Miscellaneous.

    

    (a)           No Conflicting
Agreements. The Company is
not, as of the date hereof, a party to, nor shall it, on or after the date of
this Agreement, enter into, any agreement with respect to its securities that
conflicts with the rights granted to the Holders in this Agreement. The Company
represents and warrants that the rights granted to the Holders hereunder do not
in any way conflict with the rights granted to the holders of the Company’s
securities under any other agreements.

    

    (b)           Amendments and Waivers. The
provisions of this Agreement, including the provisions of this sentence, may not
be amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, unless the Company has obtained the
written consent of Holders of a majority of Registrable Securities.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders whose securities are being sold pursuant to a Registration Statement and
that does not directly or indirectly affect the rights of other Holders may be
given by Holders of at least a majority of the Registrable Securities being sold
by such Holders pursuant to such Registration Statement; provided that the provisions
of this sentence may not be amended, modified or supplemented except in
accordance with the provisions of the immediately preceding sentence.
Notwithstanding the foregoing, this Agreement may be amended by written
agreement signed by the Company and the Initial Purchaser, without the consent
of the Holders of Registrable Securities, to cure any ambiguity or to correct or
supplement any provision contained herein that may be defective or inconsistent
with any other provision contained herein, or to make such other provisions in
regard to matters or questions arising under this Agreement that shall not
adversely affect the interests of the Holders of Registrable Securities. Each
Holder of Registrable Securities outstanding at the time of any such amendment,
modification, supplement, waiver or consent or thereafter shall be bound by any
such amendment, modification, supplement, waiver or consent effected pursuant to
this Section NYDOCS01/1162985.5
18 9(b), whether or
not any notice, writing or marking indicating such amendment, modification,
supplement, waiver or consent appears on the Registrable Securities or is
delivered to such Holder.

such other address as such person may have furnished to the other persons
identified in this Section 9(c) in writing in accordance herewith.

    

    (d)           Approval of
Holders. Whenever the
consent or approval of Holders of a specified percentage of Registrable
Securities is required hereunder, Registrable Securities held by the Company or
its Affiliates (other than the Initial Purchaser or subsequent Holders if such
subsequent Holders are deemed to be such Affiliates solely by reason of their
holdings of such Registrable Securities) shall not be counted in determining
whether such consent or approval was given by the Holders of such required
percentage; provided, however, that this Section 9(d) shall not
apply to any consent, modification, amendment or waiver of any provision of this
agreement which would only affect the rights or remedies of Holders of
Registrable Securities who are Affiliates of the Company and which would not
adversely affect the rights or remedies of any Holder of Registrable Securities
that is not an Affiliate of the Company.

    

    (e)           Successors and
Assigns. Any person who
purchases any Registrable Securities from the Initial Purchaser
shall be deemed, for purposes of this Agreement, to be an assignee of the
Initial Purchaser. This Agreement shall inure to the benefit of and be binding
upon the successors and assigns of each of the parties and shall inure to the
benefit of and be binding upon each Holder of any Registrable Securities,
provided that nothing herein shall be deemed to permit any assignment, transfer
or other disposition of Registrable Securities in violation of the terms of the
Indenture. If any transferee of any Holder shall acquire Registrable Securities,
in any manner, whether by operation of law or otherwise, such Registrable
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Registrable Securities, such person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement and such person shall be entitled to
receive the benefits hereof.

    

    (f)           Counterparts. This Agreement
may be executed in any number of counterparts and by the parties hereto in
separate counterparts, each of which when so executed shall be deemed to be
original and all of which taken together shall constitute one and the same
agreement.

    

    (g)           Headings. The headings in this Agreement are
for convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

    

    (h)           Governing Law. THIS AGREEMENT
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK.

    

    (i)            
Waiver of Jury Trial.
THE COMPANY, THE INITIAL PURCHASER AND EACH HOLDER HEREBY WAIVES ALL
RIGHTS TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED UPON CONTRACT, TORT OR
OTHERWISE) IN ANY WAY ARISING OUT OF OR RELATING TO THIS AGREEMENT. The Company,
the Initial Purchaser and each Holder agree that a final judgment in any such
proceeding brought in any such court shall be conclusive and binding upon such
party and may be enforced in any other courts in the jurisdiction of which such
party is or may be subject, by suit upon such judgment.

    
      
         

      

      
        19

        
          

        

      

      
         

      

    

     

    (j)           Agent for Service
of Process. The Company
irrevocably appoints Jeffrey Tindell of Skadden, Arps, Slate, Meagher & Flom
LLP as its authorized agent in the Borough of Manhattan in The City of New York
upon which process may be served in any such suit or proceeding, and agrees that
service of process upon such agent, and written notice of said service to the
Company by the person serving the same to the address provided in Section 9(c),
shall be deemed in every respect effective service of process upon the Company
in any such suit or proceeding. The Company further agrees to take any and all
action as may be necessary to maintain such designation and appointment of such
agent in full force and effect for a period of seven years from the date of this
Agreement.

    

    (k)           Severability. If any term,
provision, covenant or restriction of this Agreement is held to be invalid,
illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated thereby, and the
parties hereto shall use their reasonable best efforts to find and employ an
alternative means to achieve the same or substantially the same result as that
contemplated by such term, provision, covenant or restriction, it being intended
that all of the rights and privileges of the parties shall be enforceable to the
fullest extent permitted by law.

    

    (l)           Entire
Agreement. This Agreement
is intended by the parties as a final expression of their agreement and is
intended to be a complete and exclusive statement of the agreement and
understanding of the parties hereto in respect of the subject matter contained
herein and the registration rights granted by the Company with respect to the
Registrable Securities. Except as provided in the Purchase Agreement, the
Indenture and the Notes, there are no restrictions, promises, warranties or
undertakings, other than those set forth or referred to herein, with respect to
the registration rights granted by the Company with respect to the Registrable
Securities. This Agreement supersedes all prior agreements and undertakings
among the parties with respect to such registration rights. No party hereto
shall have any rights, duties or obligations other than those specifically set
forth in this Agreement, the Indenture and the Notes.

    

    (m)           Survival.
The respective
indemnities, agreements, representations, warranties and each other provision
set forth in this Agreement or made pursuant hereto shall remain in full force
and effect regardless of any investigation (or statement as to the results
thereof) made by or on behalf of any Holder, any director, officer or partner of
such Holder, any agent or underwriter or any director, officer or partner
thereof, or any controlling Person of any of the foregoing, and shall survive
delivery of and payment for the Registrable Securities pursuant to the Purchase
Agreement and the transfer and registration of Registrable Securities by such
Holder.

    

    (n)           Termination. This Agreement
and the obligations of the parties hereunder shall terminate upon the later of
(i) the end of the Effectiveness Period and (ii) the date on which restrictive
legends from the Notes (except for any restrictive legends with respect to Notes
held by Affiliates) have been removed, except, in each case, for any liabilities
or obligations under Section 4, 5 or 6 hereof and the obligations to make
payments of and provide for liquidated damages under Section 2(e) hereof to the
extent such damages accrue prior to the end of the Effectiveness Period, each of
which shall remain in effect in accordance with its terms.
