              Execution, Authentication,
      Delivery and Dating.

            

    

     

    Two
Officers of the Company shall sign the Securities on behalf of the Company by
manual or facsimile signature.  If an Officer of the Company whose
signature is on a Security no longer holds that office at the time the Security
is authenticated, the Security shall be valid nevertheless.

     

    A
Security shall not be entitled to any benefit under this Indenture or be valid
or obligatory for any purpose until authenticated by the manual signature of an
authorized signatory of the Trustee, which signature shall be conclusive
evidence that the Security has been authenticated under this
Indenture.  Notwithstanding the foregoing, if any Security has been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company delivers such Security to the Trustee for cancellation as
provided in Section 2.13, together with a written statement (which need not
comply with Section 10.05 and need not be accompanied by an Opinion of Counsel)
stating that such Security has never been issued and sold by the Company, for
all purposes of this Indenture such Security shall be deemed never to have been
authenticated and delivered hereunder and shall never be entitled to the
benefits of this Indenture.

     

    At any
time and from time to time after the execution and delivery of this Indenture,
the Company may deliver Securities of any series executed by the Company to the
Trustee for authentication, and the Trustee shall authenticate and deliver such
Securities for original issue upon a Company Order for the authentication and
delivery of such Securities or pursuant to such procedures acceptable to the
Trustee as may be specified from time to time by Company Order.  Such
order shall specify the amount of the Securities to be authenticated, the date
on which the original issue of Securities is to be authenticated, the name or
names of the initial Holder or Holders and any other terms of the Securities of
such series not otherwise determined.  If provided for in such
procedures, such Company Order may authorize (1) authentication and delivery of
Securities of such series for original issue from time to time, with certain
terms (including, without limitation, the Maturity dates or dates, original
issue date or dates and interest rate or rates) that differ from Security to
Security and (2) may authorize authentication and delivery pursuant to oral or
electronic instructions from the Company or its duly authorized agent, which
instructions shall be promptly confirmed in writing.

     

    If the
form or terms of the Securities of the series have been established in or
pursuant to one or more Board Resolutions as permitted by Section 2.01, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive (in addition to the Company Order referred to

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    above and
the other documents required by Section 10.04), and (subject to Section 7.01)
shall be fully protected in relying upon:

     

    ii)           an
Officers’ Certificate setting forth the Board Resolution and, if applicable, an
appropriate record of any action taken pursuant thereto, as contemplated by the
last paragraph of Section 2.01; and

     

    iii)           an
Opinion of Counsel to the effect that:

     

    (i)           the
form of such Securities has been established in conformity with the provisions
of this Indenture;

     

    (ii)           the
terms of such Securities have been established in conformity with the provisions
of this Indenture; and

     

    (iii)           that
such Securities when authenticated and delivered by the Trustee and issued by
the Company in the manner and subject to any conditions specified in such
Opinion of Counsel, will constitute valid and binding obligations of the
Company, enforceable against the Company in accordance with their terms, except
as the enforceability thereof may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance or other similar
laws in effect from time to time affecting the rights of creditors generally,
and the application of general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

     

    If all
the Securities of any series are not to be issued at one time, it shall not be
necessary to deliver an Officers’ Certificate and Opinion of Counsel at the time
of issuance of each such Security, but such Officers’ Certificate and Opinion of
Counsel shall be delivered at or before the time of issuance of the first
Security of the series to be issued.

     

    The
Trustee shall not be required to authenticate such Securities if the issuance of
such Securities pursuant to this Indenture would affect the Trustee’s own
rights, duties or immunities under the Securities and this Indenture or
otherwise in a manner not reasonably acceptable to the Trustee.

     

    The
Trustee may appoint an authenticating agent acceptable to the Company to
authenticate Securities.  Unless limited by the terms of such
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so.  Each reference in this Indenture to authentication
by the Trustee includes authentication by such agent.  An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company.

     

    Each
Security shall be dated the date of its authentication.

              Registrar and Paying
      Agent.

            

    

     

    The
Company shall maintain an office or agency for each series of Securities where
Securities of such series may be presented for registration of transfer or
exchange (“Registrar”) and an office or agency where Securities of such series
may be presented for

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    payment
(“Paying Agent”).  The Registrar shall keep a register of the
Securities of such series and of their transfer and exchange.  The
Company may appoint one or more co-registrars and one or more additional paying
agents.  The term “Registrar” includes any co-registrar and the term
“Paying Agent” includes any additional paying agent.

     

    The
Company shall enter into an appropriate agency agreement with any Registrar or
Paying Agent not a party to this Indenture.  The agreement shall
implement the provisions of this Indenture that relate to such
Agent.  The Company shall notify the Trustee of the name and address
of any Agent not a party to this Indenture.  The Company may change
any Paying Agent or Registrar without notice to any Holder.  If the
Company fails to appoint or maintain another entity as Registrar or Paying
Agent, the Trustee shall act as such.  The Company or any Subsidiary
may act as Paying Agent or Registrar.

     

    The
Company initially appoints the Trustee as Registrar and Paying
Agent.

              Paying Agent to Hold Money in
      Trust.

            

    

     

    The
Company shall require each Paying Agent other than the Trustee to agree in
writing that the Paying Agent will hold in trust for the benefit of Holders or
the Trustee all money held by the Paying Agent for the payment of principal of,
premium, if any, or interest on or any Additional Amounts with respect to
Securities and will notify the Trustee of any default by the Company in making
any such payment.  While any such default continues, the Trustee may
require a Paying Agent to pay all money held by it to the Trustee and to account
for any funds disbursed.  The Company at any time may require a Paying
Agent to pay all money held by it to the Trustee and to account for any funds
disbursed.  Upon payment over to the Trustee and upon accounting for
any funds disbursed, the Paying Agent (if other than the Company or a
Subsidiary) shall have no further liability for the money.  If the
Company or a Subsidiary acts as Paying Agent, it shall segregate and hold in a
separate trust fund for the benefit of the Holders all money held by it as
Paying Agent.  Each Paying Agent shall otherwise comply with TIA
§ 317(b).

      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 shall
otherwise comply with TIA § 312(a).  If the Trustee is not the
Registrar with respect to a series of Securities, the Company shall furnish to
the Trustee at least five Business Days before each Interest Payment Date with
respect to such series of Securities, and at such other times as the Trustee may
request in writing, a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of Holders of such series, and the
Company shall otherwise comply with TIA § 312(a).

      Exchange.

            

    

     

    Except as
set forth in Section 2.17 or as may be provided pursuant to
Section 2.01:

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    When
Securities of any series are presented to the Registrar with the request to
register the transfer of such Securities or to exchange such Securities for an
equal principal amount of Securities of the same series of like tenor and of
other authorized denominations, the Registrar shall register the transfer or
make the exchange as requested if its requirements and the requirements of this
Indenture for such transactions are met; provided, however, that the
Securities presented or surrendered for registration of transfer or exchange
shall be duly endorsed or accompanied by a written instruction of transfer in
form reasonably satisfactory to the Registrar duly executed by the Holder
thereof or by his attorney, duly authorized in writing, on which instruction the
Registrar can rely.

     

    To permit
registrations of transfers and exchanges, the Company shall execute and the
Trustee shall authenticate Securities at the Registrar’s written request and
submission of the Securities or Global Securities.  No service charge
shall be made to a Holder for any registration of transfer or exchange (except
as otherwise expressly permitted herein), but the Company may require payment of
a sum sufficient to cover any transfer tax or similar governmental charge
payable in connection therewith (other than such transfer tax or similar
governmental charge payable upon exchanges pursuant to Section 2.12, 3.07 or
9.05). The Trustee shall authenticate Securities in accordance with the
provisions of Section 2.04.  Notwithstanding any other provisions of
this Indenture to the contrary, the Company shall not be required to register
the transfer or exchange of (a) any Security selected for redemption in whole or
in part pursuant to Article III, except the unredeemed portion of any Security
being redeemed in part, or (b) any Security during the period beginning 15
Business Days prior to the mailing of notice of any offer to repurchase
Securities of the series required pursuant to the terms thereof or of redemption
of Securities of a series to be redeemed and ending at the close of business on
the day of mailing.

              Replacement
      Securities.

            

    

     

    If any
mutilated Security is surrendered to the Trustee, or if the Holder of a Security
claims that the Security has been destroyed, lost or stolen and the Company and
the Trustee receive evidence to their satisfaction of the destruction, loss or
theft of such Security, the Company shall issue and the Trustee shall
authenticate a replacement Security of the same series if the Trustee’s
requirements are met.  If any such mutilated, destroyed, lost or
stolen Security has become or is about to become due and payable, the Company in
its discretion may, instead of issuing a new Security, pay such
Security.  If required by the Trustee or the Company, such Holder must
furnish an indemnity bond that is sufficient in the judgment of the Trustee and
the Company to protect the Company, the Trustee, any Agent or any authenticating
agent from any loss that any of them may suffer if a Security is
replaced.  The Company and the Trustee may charge a Holder for their
expenses in replacing a Security.

     

    Every
replacement Security is an additional obligation of the Company.

interest in a Global Security effected by the Trustee hereunder and those
described in this Section 2.10 as not outstanding.

     

    If a
Security is replaced pursuant to Section 2.09, it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Security
is held by a bona fide purchaser.

     

    If the
principal amount of any Security is considered paid under Section 4.01, it
ceases to be outstanding and interest on it ceases to accrue.

     

    A
Security does not cease to be outstanding because the Company or an Affiliate of
the Company holds the Security.

    In
determining whether the Holders of the required principal amount of Securities
have concurred in any direction, amendment, supplement, waiver or consent,
(a) the principal amount of an Original Issue Discount Security shall be
the principal amount thereof that would be due and payable as of the date of
such determination upon acceleration of the Maturity thereof pursuant to Section
6.02, (b) the principal amount of a Security denominated in a foreign
currency shall be the Dollar equivalent, as determined by the Company by
reference to the noon buying rate in The City of New York for cable transfers
for such currency, as such rate is certified for customs purposes by the Federal
Reserve Bank of New York (the “Exchange Rate”) on the date of original issuance
of such Security, of the principal amount (or, in the case of an Original Issue
Discount Security, the Dollar equivalent, as determined by the Company by
reference to the Exchange Rate on the date of original issuance of such
Security, of the amount determined as provided in (a) above), of such Security
and (c) Securities owned by the Company or any other obligor upon the
Securities or any Affiliate of the Company or of such other obligor shall be
disregarded, except that, for the purpose of determining whether the Trustee
shall be protected in relying upon any such direction, amendment, supplement,
waiver or consent, only Securities that a Responsible Officer of the Trustee
actually knows are so owned shall be so disregarded.

    Until
definitive Securities of any series are ready for delivery, the Company may
prepare and the Trustee shall authenticate temporary
Securities.  Temporary Securities shall be substantially in the form
of definitive Securities, but may have variations that the Company considers
appropriate for temporary Securities.  Without unreasonable delay, the
Company shall prepare and the Trustee shall authenticate definitive Securities
in exchange for temporary Securities.  Until so exchanged, the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

registration of transfer, exchange, payment or redemption or for credit against
any sinking fund payment.  The Trustee shall cancel all Securities
surrendered for registration of transfer, exchange, payment, redemption,
replacement or cancellation or for credit against any sinking
fund.  Unless the Company shall direct in writing that canceled
Securities be returned to it, after written notice to the Company all canceled
Securities held by the Trustee shall be disposed of in accordance with the usual
disposal procedures of the Trustee, and the Trustee shall maintain a record of
their disposal.  The Company may not issue new Securities to replace
Securities that have been paid or that have been delivered to the Trustee for
cancellation.

    Unless
otherwise provided as contemplated by Section 2.01, interest (except
defaulted interest) on any Security that is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Persons who
are registered Holders of that Security at the close of business on the record
date next preceding such Interest Payment Date, even if such Securities are
canceled after such record date and on or before such Interest Payment
Date.  The Holder must surrender a Security to a Paying Agent to
collect principal payments.  Unless otherwise provided with respect to
the Securities of any series, the Company will pay the principal of, premium (if
any) and interest on and any Additional Amounts with respect to the Securities
in Dollars.  Such amounts shall be payable at the offices of the
Trustee or any Paying Agent, provided that at the option
of the Company, the Company may pay such amounts (1) by wire transfer with
respect to Global Securities or (2) by check payable in such money mailed to a
Holder’s registered address with respect to any Securities.

     

    If the
Company defaults in a payment of interest on the Securities of any series, the
Company shall pay the defaulted interest in any lawful manner plus, to the
extent lawful, interest on the defaulted interest, in each case at the rate
provided in the Securities of such series and in Section 4.01.  The
Company may pay the defaulted interest to the Persons who are Holders on a
subsequent special record date.  At least 15 days before any special
record date selected by the Company, the Company (or the Trustee, in the name of
and at the expense of the Company upon 20 days’ prior written notice from the
Company setting forth such special record date and the interest amount to be
paid) shall mail to Holders a notice that states the special record date, the
related payment date and the amount of such interest to be paid.

    Global
Securities; Book-Entry Provisions.

     

    If
Securities of a series are issuable in global form as a Global Security, as
contemplated by Section 2.01, then, notwithstanding clause (10) of Section
2.01 and the provisions of Section 2.02, any such Global Security shall
represent such of the outstanding Securities of such series as shall be
specified therein and may provide that it shall represent the aggregate amount
of outstanding Securities from time to time endorsed thereon and that the
aggregate amount of outstanding Securities represented thereby may from time to
time be reduced or increased, as appropriate, to reflect exchanges, transfers or
redemptions.  Any endorsement of a Global Security to reflect the
amount, or any increase or decrease in the amount, of outstanding Securities
represented thereby shall be made by the Trustee (i) in such manner and upon
instructions given by such Person or Persons as shall be specified in such
Security or in a Company Order to be delivered to the Trustee pursuant to
Section 2.04 or (ii) otherwise in accordance with written instructions or
such other written form of instructions as is customary for the Depositary for
such Security, from such Depositary or its nominee on behalf of any Person
having a beneficial interest in such Global Security.  Subject to the
provisions of Section 2.04 and, if applicable, Section 2.12, the Trustee shall
deliver and redeliver any Security in permanent global form in the manner and
upon instructions given by the Person or Persons specified in such Security or
in the applicable Company Order.  With respect to the Securities of
any series that are represented by a Global Security, the Company authorizes the
execution and delivery by the Trustee of a letter of representations or other
similar agreement or instrument in the form customarily provided for by the
Depositary appointed with respect to such Global Security.  Any Global
Security may be deposited with the Depositary or its nominee, or may remain in
the custody of the Trustee or the Security Custodian therefor pursuant to a FAST
Balance Certificate Agreement or similar agreement between the Trustee and the
Depositary.  If a Company Order has been, or simultaneously is,
delivered, any instructions by the Company with respect to endorsement or
delivery or redelivery of a Security in global form shall be in writing but need
not comply with Section 10.05 and need not be accompanied by an Opinion of
Counsel.

     

    Members
of, or participants in, the Depositary (“Agent Members”) shall have no rights
under this Indenture with respect to any Global Security held on their behalf by
the Depositary, or the Trustee or the Security Custodian as its custodian, or
under such Global Security, and the Depositary may be treated by the Company,
the Trustee or the Security Custodian and any agent of the Company, the Trustee
or the Security Custodian as the absolute owner of such Global Security for all
purposes whatsoever.  Notwithstanding the foregoing, (i) the
registered holder of a Global Security of a series 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 of
Securities of such series is entitled to take under this Indenture or the
Securities of such series and (ii) nothing herein shall prevent the Company, the
Trustee or the Security Custodian, or any agent of the Company, the Trustee or
the Security Custodian, from giving effect to any written certification, proxy
or other authorization furnished by the Depositary or shall impair, as between
the Depositary and its Agent Members, the operation of customary practices
governing the exercise of the rights of a beneficial owner of any
Security.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    Notwithstanding
Section 2.08, and except as otherwise provided pursuant to Section
2.01:  Transfers of a Global Security shall be limited to transfers of
such Global Security in whole, but not in part, to the Depositary, its
successors or their respective nominees.  Interests of beneficial
owners in a Global Security may be transferred in accordance with the rules and
procedures of the Depositary.  Securities shall be transferred to all
beneficial owners in exchange for their beneficial interests in a Global
Security if, and only if, either (1) the Depositary notifies the Company that it
is unwilling or unable to continue as Depositary for the Global Security and a
successor Depositary is not appointed by the Company within 90 days of such
notice or (2) an Event of Default has occurred with respect to such series and
is continuing and the Registrar has received a request from the Depositary to
issue Securities in lieu of all or a portion of the Global Security (in which
case the Company shall deliver Securities within 30 days of such
request).

     

    In
connection with any transfer of a portion of the beneficial interests in a
Global Security to beneficial owners pursuant to this Section 2.17, the
Registrar shall reflect on its books and records the date and a decrease in the
principal amount of the Global Security in an amount equal to the principal
amount of the beneficial interests in the Global Security to be transferred, and
the Company shall execute, and the Trustee upon receipt of a Company Order for
the authentication and delivery of Securities shall authenticate and deliver,
one or more Securities of the same series of like tenor and amount.

     

    In
connection with the transfer of all the beneficial interests in a Global
Security to beneficial owners pursuant to this Section 2.17, the Global Security
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
interests in the Global Security, an equal aggregate principal amount of
Securities of authorized denominations.

     

    Neither
the Company nor the Trustee will have any responsibility or liability for any
aspect of the records relating to, or payments made on account of, Securities by
the Depositary, or for maintaining, supervising or reviewing any records of the
Depositary relating to such Securities.  Neither the Company nor the
Trustee shall be liable for any delay by the related Global Security Holder or
the Depositary in identifying the beneficial owners, and each such Person may
conclusively rely on, and shall be protected in relying on, instructions from
such Global Security Holder or the Depositary for all purposes (including with
respect to the registration and delivery, and the respective principal amounts,
of the Securities to be issued).

              Notice to the
      Trustee.

            

    

     

    If the
Company elects to redeem Securities of any series pursuant to this Indenture, it
shall notify the Trustee of the Redemption Date and the principal amount of
Securities of such series to be redeemed.  The Company shall so notify
the Trustee at least 45 days before the Redemption Date (unless a shorter notice
shall be satisfactory to the Trustee) by delivering to the Trustee an Officers’
Certificate stating that such redemption will comply with the provisions of this
Indenture and of the Securities of such series.  Any such notice may
be canceled at any time prior to the mailing of such notice of such redemption
to any Holder and shall thereupon be void and of no effect.  A
redemption or notice thereof may be subject to one or more
conditions.

              Selection of Securities To Be
      Redeemed.

            

    

     

    If less
than all the Securities of any series are to be redeemed (unless all of the
Securities of such series of a specified tenor are to be redeemed), the
particular Securities to be redeemed shall be selected not more than 60 days
prior to the Redemption Date by the Trustee from the outstanding Securities of
such series (and tenor) not previously called for redemption, either at random,
by lot or by such other method as the Trustee shall deem fair and appropriate
and that may provide for the selection for redemption of portions (equal to the
minimum authorized denomination for Securities of that series or any integral
multiple thereof) of the principal amount of Securities of such series of a
denomination larger than the minimum authorized denomination for Securities of
that series or of the principal amount of Global Securities of such
series.

     

    The
Trustee shall promptly notify the Company and the Registrar in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be
redeemed.

     

    For
purposes of this Indenture, unless the context otherwise requires, all
provisions relating to redemption of Securities shall relate, in the case of any
of the Securities redeemed or to be redeemed only in part, to the portion of the
principal amount thereof which has been or is to be redeemed.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    Notice of
Redemption.

     

    Notice of
redemption shall be given by first-class mail, postage prepaid, mailed not less
than 30 nor more than 60 days prior to the Redemption Date, to each Holder of
Securities to be redeemed, at the address of such Holder appearing in the
register of Securities maintained by the Registrar.

     

    All
notices of redemption shall identify the Securities to be redeemed and shall
state:

     

    (1)           the
Redemption Date;

     

    (2)           the
Redemption Price;

     

    (3)           that,
unless the Company defaults in making the redemption payment, interest on
Securities called for redemption ceases to accrue on and after the Redemption
Date, and the only remaining right of the Holders of such Securities is to
receive payment of the Redemption Price upon surrender to the Paying Agent of
the Securities redeemed;

     

    (4)           if
any Security is to be redeemed in part, the portion of the principal amount
thereof to be redeemed and that on and after the Redemption Date, upon surrender
for cancellation of such Security to the Paying Agent, a new Security or
Securities in the aggregate principal amount equal to the unredeemed portion
thereof will be issued without charge to the Holder;

     

    (5)           that
Securities called for redemption must be surrendered to the Paying Agent to
collect the Redemption Price and the name and address of the Paying
Agent;

     

    (6)           that
the redemption is for a sinking or analogous fund, if such is the
case;

     

    (7)           the
CUSIP number, if any, relating to such Securities; and

     

    (8)           if
the redemption or notice thereof is subject to one or more conditions, a
statement to such effect and the condition or conditions precedent.

     

    Notice of
redemption of Securities to be redeemed at the election of the Company shall be
given by the Company or, at the Company’s written request, by the Trustee in the
name and at the expense of the Company.

    Once
notice of redemption is mailed, unless the redemption or notice thereof is
subject to one or more conditions as specified in the notice, Securities called
for redemption become due and payable on the Redemption Date and at the
Redemption Price.  Upon surrender to the Paying Agent, such Securities
called for redemption shall be paid at the Redemption Price, but interest
installments whose maturity is on or prior to such Redemption Date will be
payable on the relevant Interest Payment Dates to the Holders of record at the
close of business on the relevant record dates specified pursuant to Section
2.01.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    Deposit
of Redemption Price.

     

    On or
prior to 11:00 a.m., New York City time, on any Redemption Date, the Company
shall deposit with the Trustee or the Paying Agent (or, if the Company is acting
as the Paying Agent, segregate and hold in trust as provided in
Section 2.06) an amount of money in same day funds sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest
Payment Date) accrued interest on and any Additional Amounts with respect to,
the Securities or portions thereof which are to be redeemed on that date, other
than Securities or portions thereof called for redemption on that date which
have been delivered by the Company to the Trustee for cancellation.

     

    If the
Company complies with the preceding paragraph, then, unless the Company defaults
in the payment of such Redemption Price, interest on the Securities to be
redeemed will cease to accrue on and after the applicable Redemption Date,
whether or not such Securities are presented for payment, and the Holders of
such Securities shall have no further rights with respect to such Securities
except for the right to receive the Redemption Price upon surrender of such
Securities.  If any Security called for redemption shall not be so
paid upon surrender thereof for redemption, the principal, premium, if any, any
Additional Amounts, and, to the extent lawful, accrued interest thereon shall,
until paid, bear interest from the Redemption Date at the rate specified
pursuant to Section 2.01 or provided in the Securities or, in the case of
Original Issue Discount Securities, such Securities’ yield to
maturity.

    Upon

shall execute and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge a new Security or Securities, of the same
series and of any authorized denomination as requested by such Holder in

    Unless
otherwise specified as contemplated by Section 2.01, the Company, and any
Affiliate of the Company may, subject to applicable law, at any time purchase or
otherwise acquire Securities in the open market or by private
agreement.  Any such acquisition shall not operate as or be deemed for
any purpose to be a redemption of the indebtedness represented by such
Securities.  Any Securities purchased or acquired by the Company may
be delivered to the Trustee and, upon such delivery, the indebtedness
represented thereby shall be deemed to be satisfied. Section 2.13 shall apply to
all Securities so delivered.

    The
minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a “mandatory sinking fund
payment,” and any payment in excess of such minimum amount provided for by the

              Satisfaction of Sinking Fund
      Payments with Securities.

            

    

     

    The
Company may deliver outstanding Securities of a series (other than any
previously called for redemption) and may apply as a credit Securities of a
series that have been redeemed either at the election of the Company pursuant to
the terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, in each case in
satisfaction of all or any part of any sinking fund payment with respect to the
Securities of such series required to be made pursuant to the terms of such
series of Securities; provided that such Securities
have not been previously so credited.  Such Securities shall be
received and credited for such purpose by the Trustee at the Redemption Price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced
accordingly.

              Redemption of Securities for
      Sinking Fund.

            

    

     

    Not less
than 45 days prior (unless a shorter period shall be satisfactory to the
Trustee) to each sinking fund payment date for any series of Securities, the
Company will deliver to the Trustee an Officers’ Certificate of the Company
specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash and the portion thereof, if any, which is to be
satisfied by delivery of or by crediting Securities of that series pursuant to
Section 3.10 and will also deliver or cause to be delivered to the Trustee any
Securities to be so delivered.  Failure of the Company to timely
deliver or cause to be delivered such Officers’ Certificate and Securities
specified in this paragraph, if any, shall not constitute a default but shall
constitute the election of the Company (i) that the mandatory sinking fund
payment for such series due on the next succeeding sinking fund payment date
shall be paid entirely in cash without the option to deliver or credit
Securities of such series in respect thereof and (ii) that the Company will make
no optional sinking fund payment with respect to such series as provided in this
Section.

     

    If the
sinking fund payment or payments (mandatory or optional or both) to be made in
cash on the next succeeding sinking fund payment date plus any unused balance of
any preceding sinking fund payments made in cash shall exceed $100,000 (or the
Dollar equivalent thereof based on the applicable Exchange Rate on the date of
original issue of the applicable Securities) or a lesser sum if the Company
shall so request with respect to the Securities of any particular series, such
cash shall be applied on the next succeeding sinking fund payment date to the
redemption of Securities of such series at the sinking fund redemption price
together with accrued interest to the date fixed for redemption.  If
such amount shall be $100,000 (or the Dollar equivalent thereof as aforesaid) or
less and the Company makes no such request then it shall be carried over until a
sum in excess of $100,000 (or the Dollar equivalent thereof as aforesaid) is
available.  Not less than 30 days before each such sinking fund
payment date, the Trustee shall select the Securities to be redeemed upon such
sinking fund payment date in the manner specified in Section 3.03 and cause
notice of the redemption thereof to be given in the name of and at the expense
of the Company in the manner provided in Section 3.04.  Such
notice

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    having
been duly given, the redemption of such Securities shall be made upon the terms
and in the manner stated in Sections 3.05, 3.06 and 3.07.

    The
Company shall pay interest (including post-petition interest in any proceeding

equal to the then applicable interest rate on the Securities to the extent
lawful; and it shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue installments of interest and any

    The
Company will maintain in each Place of Payment for any series of Securities an
office or agency (which may be an office of the Trustee, the Registrar or the
Paying Agent) where Securities of that series may be presented for registration
of transfer or exchange, where Securities of that series may be presented for
payment and where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served. Unless otherwise
designated by the Company by written notice to the Trustee, such office or
agency shall be the office of the Trustee at 1445 Ross Avenue, 2nd Floor,
MAC T5303-02J, Dallas, TX 75202.  The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of such
office or agency.  If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee.

     

    The
Company may also from time to time designate one or more other offices or
agencies where the Securities of one or more series may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designations; provided,
however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in each
Place of Payment for Securities of any series 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.

              Events of
      Default.

            

    

     

    Unless
either inapplicable to a particular series or specifically deleted or modified
in or pursuant to the supplemental indenture or Board Resolution establishing
such series of Securities or in the form of Security for such series, an “Event
of Default,” wherever used herein with respect to Securities of any series,
occurs if:

     

    (5)           the
Company defaults in the payment of interest on or any Additional Amounts with
respect to any Security of that series when the same becomes due and payable and
such default continues for a period of 30 days;

     

    (6)           the
Company defaults in the payment of (A) the principal of any Security of that
series at its Maturity or (B) premium (if any) on any Security of that series
when the same becomes due and payable;

     

    (7)           the
Company defaults in the deposit of any sinking fund payment, when and as due by
the terms of a Security of that series, and such default continues for a period
of 30 days;

     

    (8)           the
Company fails to comply with any of its other covenants or agreements in, or
provisions of, the Securities of such series or this Indenture (other than an
agreement, covenant or provision that has expressly been included in this
Indenture solely for the benefit of one or more series of Securities other than
that series) which shall not have been remedied within the specified period
after written notice, as specified in the last paragraph of this Section
6.01;

     

    (9)           the
Company pursuant to or within the meaning of any Bankruptcy Law:

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    (a)           commences
a voluntary case,

     

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

     

    (c)           consents
to the appointment of a Bankruptcy Custodian of it or for all or substantially
all of its property, or

     

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

     

    (10)           a
court of competent jurisdiction enters an order or decree under any Bankruptcy
Law that remains unstayed and in effect for 90 days and that:

     

    (a)           is
for relief against the Company as debtor in an involuntary case,

     

    (b)           appoints
a Bankruptcy Custodian of the Company or a Bankruptcy Custodian for all or
substantially all of the property of the Company, or

     

    (c)           orders
the liquidation of the Company;

     

    (11)           any
other Event of Default provided with respect to Securities of that series
occurs.

     

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

     

    The
Trustee shall not be deemed to know or have notice of any Default or Event of
Default unless a Responsible Officer of the Trustee has actual knowledge thereof
or unless written notice of any event which is in fact such a Default or Event
of Default is received by the Trustee at the Corporate Trust Office of the
Trustee, and such notice references the Securities and this
Indenture.

     

    When a
Default is cured, it ceases.

     

    Notwithstanding
the foregoing provisions of this Section 6.01, if the principal of, premium (if
any) or interest on or Additional Amounts with respect to any Security is
payable in a currency or currencies (including a composite currency) other than
Dollars and such currency or currencies are not available to the Company for
making payment thereof due to the imposition of exchange controls or other
circumstances beyond the control of the Company (a “Conversion Event”), the
Company will be entitled to satisfy its obligations to Holders of the Securities
by making such payment in Dollars in an amount equal to the Dollar equivalent of
the amount payable in such other currency, as determined by the Company by
reference to the Exchange Rate on the date of such payment, or, if such rate is
not then available, on the basis of the most recently available Exchange
Rate.  Notwithstanding the foregoing provisions of this Section 6.01,
any payment made under such circumstances in Dollars where the required payment
is in a currency other than Dollars will not constitute an Event of Default
under this Indenture.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    Promptly
after the occurrence of a Conversion Event, the Company shall give written
notice thereof to the Trustee; and the Trustee, promptly after receipt of such
notice, shall give notice thereof in the manner provided in Section 10.02 to the
Holders.  Promptly after the making of any payment in Dollars as a
result of a Conversion Event, the Company shall give notice in the manner
provided in Section 10.02 to the Holders, setting forth the applicable Exchange
Rate and describing the calculation of such payments.

     

    A Default
under clause (4) or (7) of this Section 6.01 is not an Event of Default until
the Trustee notifies the Company, or the Holders of at least 25% in principal
amount of the then outstanding Securities of the series affected by such Default
notify the Company and the Trustee, of the Default, and the Company fails to
cure the Default within 90 days after receipt of the notice.  The
notice must specify the Default, demand that it be remedied and state that the
notice is a “Notice of Default.”

     

    
      	
              SECTION
      6.02

            	
              Acceleration.

            

    

     

    If an
Event of Default with respect to any Securities of any series at the time
outstanding (other than an Event of Default specified in clause (5) or (6) of
Section 6.01) occurs and is continuing, the Trustee by notice to the Company, or
the Holders of at least 25% in principal amount of the then outstanding
Securities of the series affected by such Event of Default by notice to the
Company and the Trustee, may declare the principal of (or, if any such
Securities are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) and all accrued and
unpaid interest on all then outstanding Securities of such series to be due and
payable.  Upon any such declaration, the amounts due and payable on
the Securities shall be due and payable immediately.  If an Event of
Default specified in clause (5) or (6) of Section 6.01 hereof occurs, such
amounts shall ipso
facto become and be immediately due and payable without any declaration,
notice or other act on the part of the Trustee or any Holder.  The
Holders of a majority in principal amount of the then outstanding Securities of
the series affected by such Event of Default, by written notice to the Trustee,
may rescind an acceleration and its consequences (other than nonpayment of
principal of or premium or interest on or any Additional Amounts with respect to
the Securities) if the rescission would not conflict with any judgment or decree
and if all existing Events of Default with respect to Securities of that series
have been cured or waived, except nonpayment of principal, premium, interest or
any Additional Amounts that has become due solely because of the
acceleration.

     

    
      	
              SECTION
      6.03

            	
              Other
      Remedies.

            

    

     

    If an
Event of Default occurs and is continuing, the Trustee may pursue any available
remedy to collect the payment of principal of, or premium, if any, or interest
on the Securities or to enforce the performance of any provision of the
Securities or this Indenture.

     

    The
Trustee may maintain a proceeding even if it does not possess any of the
Securities or does not produce any of them 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.  All
remedies are cumulative to the extent permitted by law.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    Waiver of
Defaults.

     

    Subject
to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the
then outstanding Securities of any series by notice to the Trustee may waive an
existing or past Default or Event of Default with respect to such series and its
consequences (including waivers obtained in connection with a tender offer or
exchange offer for Securities of such series or a solicitation of consents in
respect of Securities of such series, provided that in each case
such offer or solicitation is made to all Holders of then outstanding Securities
of such series), except (1) a continuing Default or Event of Default in the
payment of the principal of, or premium, if any, or interest on or any
Additional Amounts with respect to any Security or (2) a continued Default
in respect of a provision that under Section 9.02 cannot be amended or
supplemented without the consent of each Holder affected.  Upon any
such waiver, such Default shall cease to exist, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other Default or
impair any right consequent thereon.

              Control by
      Majority.

            

    

     

    With
respect to Securities of any series, the Holders of a majority in principal
amount of the then outstanding Securities of such series may direct in writing
the time, method and place of conducting any proceeding for any remedy available
to the Trustee or exercising any trust or power conferred on it relating to or
arising under an Event of Default described in clause (1), (2), (3) or (7)
of Section 6.01.  However, the Trustee may refuse to follow any
direction that conflicts with applicable law or this Indenture, that the Trustee
determines may be unduly prejudicial to the rights of other Holders, or that may
involve the Trustee in personal liability; provided, however, that the
Trustee may take any other action deemed proper by the Trustee that is not
inconsistent with such direction.  Prior to taking any action
hereunder, the Trustee shall be entitled to indemnification satisfactory to it
in its sole discretion from Holders directing the Trustee against all losses and
expenses caused by taking or not taking such action.

              Limitations on
      Suits.

            

    

     

    Subject
to Section 6.07 hereof, a Holder of a Security of any series may pursue a remedy
with respect to this Indenture or the Securities of such series only
if:

     

    (1)           the
Holder gives to the Trustee written notice of a continuing Event of Default with
respect to such series;

     

    (2)           the
Holders of at least 25% in principal amount of the then outstanding Securities
of such series make a written request to the Trustee to pursue the
remedy;

     

    (3)           such
Holder or Holders offer to the Trustee indemnity satisfactory to the Trustee
against any loss, liability or expense;

     

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

     

    (5)         
during
such 60-day period the Holders of a majority in principal amount of the
Securities of that series do not give the Trustee a direction inconsistent with
the request.

     

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

              Rights of Holders to Receive
      Payment.

            

    

     

    Notwithstanding
any other provision of this Indenture, the right of any Holder of a Security to
receive payment of principal of and premium, if any, and interest on and any
Additional Amounts with respect to the Security, on or after the respective due
dates expressed in the Security, or to bring suit for the enforcement of any
such payment on or after such respective dates, is absolute and unconditional
and shall not be impaired or affected without the consent of the
Holder.

              Collection Suit by
      Trustee.

            

    

     

    If an
Event of Default specified in clause (1) or (2) of Section 6.01 hereof occurs
and is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Company for the amount of
principal, premium (if any), interest and any Additional Amounts remaining
unpaid on the Securities of the series affected by the Event of Default, and
interest on overdue principal and premium, if any, and, to the extent lawful,
interest on overdue interest, and such further amount as shall be sufficient to
cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

              Trustee May File Proofs of
      Claim.

            

    

     

    The
Trustee is authorized to file such proofs of claim and other papers or documents
and to take such actions, including participating as a member, voting or
otherwise, of any committee of creditors, as may be necessary or advisable to
have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel) and the Holders allowed in any judicial proceedings relative to the
Company or its creditors or properties and shall be entitled and empowered to
collect, receive and distribute any money or other property payable or
deliverable on any such claims and any Bankruptcy Custodian in any such judicial
proceeding is hereby authorized by each Holder to make such 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 to it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.07. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.07 out of the estate in any such
proceeding, shall be denied for any reason, payment of the same shall be secured
by a lien on, and shall be paid out of, any and all distributions, dividends,
money, securities and other properties which the Holders of the Securities may
be entitled to receive in such proceeding whether in liquidation or under any
plan of reorganization or arrangement or
otherwise.  Nothing

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    herein
contained shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
thereof, or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

              Priorities.

            

    

     

    If the
Trustee collects any money pursuant to this Article VI, it shall pay out the
money in the following order:

     

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

     

    Second:  to
Holders for amounts due and unpaid on the Securities in respect of which or for
the benefit of which such money has been collected, for principal, premium (if
any), interest and any Additional Amounts ratably, without preference or
priority of any kind, according to the amounts due and payable on such
Securities for principal, premium (if any), interest and any Additional Amounts,
respectively; and

     

    Third:  to
the Company.

     

    The
Trustee, upon prior written notice to the Company, may fix record dates and
payment dates for any payment to Holders pursuant to this Article
VI.

     

    To the
fullest extent allowed under applicable law, if for the purpose of obtaining a
judgment against the Company in any court it is necessary to convert the sum due
in respect of the principal of, premium (if any) or interest on or Additional
Amounts with respect to the Securities of any series (the “Required Currency”)
into a currency in which a judgment will be rendered (the “Judgment Currency”),
the rate of exchange used shall be the rate at which in accordance with normal
banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the Business Day in The City of
New York next preceding that on which final judgment is
given.  Neither the Company nor the Trustee shall be liable for any
shortfall nor shall it benefit from any windfall in payments to Holders of
Securities under this Section 6.10 caused by a change in exchange rates between
the time the amount of a judgment against it is calculated as above and the time
the Trustee converts the Judgment Currency into the Required Currency to make
payments under this Section 6.10 to Holders of Securities, but payment of such
judgment shall discharge all amounts owed by the Company on the claim or claims
underlying such judgment.

    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 a trustee, a
court in its discretion may require the filing by any party litigant in the suit
of an undertaking to pay the costs of the suit, and the court in its discretion
may assess reasonable costs, including reasonable attorneys’ fees, against any
party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant.  This Section 6.11
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section
6.07, or a suit by a Holder or Holders of more than 10% in principal amount of
the then outstanding Securities of any series.

              Duties of
      Trustee.

            

    

     

    (a)           If
an Event of Default has occurred and is continuing, the Trustee shall exercise
such of the rights and powers vested in it by this Indenture, and use the same
degree of care and skill in such 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 with respect to the Securities of
any series:

     

    (1)           the
Trustee need perform only those duties that are specifically set forth in this
Indenture and no others, 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 or opinions furnished to the Trustee and conforming
to the requirements of this Indenture.  However, the Trustee shall
examine such certificates and opinions to determine whether, on their face, they
appear to conform to the requirements of this Indenture.

     

    (c)           The
Trustee may not be relieved from liabilities for its own negligent action, its
own negligent failure to act or its own willful misconduct, except
that:

     

    (1)           this
paragraph does not limit the effect of Section 7.01(b);

     

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

     

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

     

    (d)           Whether
or not therein expressly so provided, every provision of this Indenture that in
any way relates to the Trustee is subject to the provisions of this
Section 7.01.

     

    (e)           No
provision of this Indenture shall require the Trustee to expend or risk its own
funds or incur any liability.  The Trustee may refuse to perform any
duty or exercise any right or power unless it receives indemnity satisfactory to
it against any loss, liability or expense.

     

    (f)           The
Trustee shall not be liable for interest on any money received by it except as
the Trustee may agree in writing with the Company.  Money held in
trust by the Trustee need not be segregated from other funds except to the
extent required by law.  All money

     

    (g)

     

    received
by the Trustee shall, until applied as herein provided, be held in trust for the
payment of the principal of, premium (if any) and interest on and Additional
Amounts with respect to the Securities.

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

     

    (b)           Before
the Trustee acts or refrains from acting, it may require instruction, an
Officers’ Certificate or an Opinion of Counsel or both to be
provided.  The Trustee shall not be liable for any action it takes or
omits to take in good faith in reliance on such instruction, Officers’
Certificate or Opinion of Counsel.  The Trustee may consult at the
Company’s expense with counsel of its selection and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in reliance thereon.

     

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

     

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

     

    (e)           Unless
otherwise specifically provided in this Indenture, any demand, request,
direction or notice from the Company shall be sufficient if signed by an Officer
of the Company.

    The
Trustee in its individual or any other capacity may become the owner or pledgee
of Securities and may otherwise deal with the Company or any of its Affiliates

Default or Event of Default with respect to the Securities of any series occurs
and is continuing and it is known to the Trustee, the Trustee shall mail to
Holders of Securities of such series a notice of the Default or Event of Default

              Compensation and

    The
Company agrees to pay to the Trustee for its acceptance of this Indenture and
services hereunder such compensation as the Company and the Trustee shall from
time to time agree in writing. The Trustee’s compensation shall not be limited
by any law on compensation of a trustee of an express trust.  The
Company agrees to reimburse the Trustee upon request for all reasonable
disbursements, advances and expenses incurred by it.  Such expenses
shall include the reasonable compensation, disbursements and expenses of the
Trustee’s agents and counsel.

     

    The
Company hereby indemnifies the Trustee and any predecessor Trustee against any
and all loss, liability, damage, claim or expense, including taxes (other than
taxes based upon, measured by or determined by the income of the Trustee),
incurred by it arising out of or in connection with the acceptance or
administration of its duties under this Indenture, except as set forth in the
next following paragraph.  The Trustee shall notify the Company
promptly of any claim for which it may seek indemnity.  The Company
shall defend the claim and the Trustee shall cooperate in the
defense.  The Trustee may have separate counsel and the Company shall
pay the reasonable fees and expenses of such counsel.  The Company
need not pay for any settlement made without its consent.

     

    The
Company shall not be obligated to reimburse any expense or indemnify against any
loss or liability incurred by the Trustee through the Trustee’s negligence or
bad faith.

in Section 6.01(5) or (6) occurs, the expenses and the compensation for the
services are intended to constitute expenses of administration under any
Bankruptcy Law.

              Replacement of
      Trustee.

            

    

     

    A
resignation or removal of the Trustee and appointment of a successor Trustee
shall become effective only upon the successor Trustee’s acceptance of
appointment as provided in this Section 7.08.

     

    The
Trustee may resign and be discharged at any time with respect to the Securities
of one or more series by so notifying the Company.  The Holders of a
majority in principal amount of the then outstanding Securities of any series
may remove the Trustee with respect to the Securities of such series by so
notifying the Trustee and the Company.  The Company may remove the
Trustee if:

     

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

     

    (2)           the
Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered
with respect to the Trustee under any Bankruptcy Law;

     

    (3)           a
Bankruptcy Custodian or 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 or if a vacancy exists in the office of Trustee
for any reason, with respect to the Securities of one or more series, the
Company shall promptly appoint a successor Trustee or Trustees with respect to
the Securities of that or those series (it being understood that any such
successor Trustee may be appointed with respect to the Securities of one or more
or all of such series and that at any time there shall be only one Trustee with
respect to the Securities of any particular series).  Within one year
after the successor Trustee with respect to the Securities of any series takes
office, the Holders of a majority in principal amount of the Securities of such
series then outstanding may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.

     

    If a
successor Trustee with respect to the Securities of any series does not take
office within 30 days after the retiring or removed Trustee resigns or is
removed, the retiring or removed Trustee, the Company or the Holders of at least
10% in principal amount of the then outstanding Securities of such series may
petition any court of competent jurisdiction for the appointment of a successor
Trustee with respect to the Securities of such series.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

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

     

    In case
of the appointment of a successor Trustee with respect to all Securities, each
such 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 retiring 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, subject to
the lien provided for in Section 7.07.

     

    In case
of the appointment of a successor Trustee with respect to the Securities of one
or more (but not all) series, the Company, the retiring Trustee and each
successor Trustee with respect to the Securities of one or more (but not all)
series shall execute and deliver an indenture supplemental hereto in which each
successor Trustee shall accept such appointment and that (1) shall confer to
each successor Trustee all the rights, powers and duties of the retiring Trustee
with respect to the Securities of that or those series to which the appointment
of such successor Trustee relates, (2) if the retiring Trustee is not retiring
with respect to all Securities, shall confirm that all the rights, powers and
duties of the retiring Trustee with respect to the Securities of that or those
series as to which the retiring Trustee is not retiring shall continue to be
vested in the retiring Trustee and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one
Trustee.  Nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust, and each such Trustee
shall be trustee of a trust or trusts hereunder separate and apart from any
trust or trusts hereunder administered by any other such
Trustee.  Upon the execution and delivery of such supplemental
indenture, the resignation or removal of the retiring Trustee shall become
effective to the extent provided therein and each such successor Trustee shall
have all the rights, powers and duties of the retiring Trustee with respect to
the Securities of that or those series to which the appointment of such
successor Trustee relates.  On request of the Company or any successor
Trustee, such retiring Trustee shall transfer to such successor Trustee all
property held by such retiring Trustee as Trustee with respect to the Securities
of that or those series to which the appointment of such successor Trustee
relates.

     

    Notwithstanding
replacement of the Trustee or Trustees pursuant to this Section 7.08, the
obligations of the Company under Section 7.07 shall continue for the
benefit of the retiring Trustee or Trustees.

authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities 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 Securities or in this Indenture provided
that the certificate of the Trustee shall have.

nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge the
entire indebtedness on the Securities of such series for principal and interest
to the date of such deposit (in the case of Securities which have become due and
payable) or for principal, premium, if any, and interest to the Stated Maturity
or Redemption Date, as the case may be; or

this Section 8.01(b) is specified as not being applicable to Securities of a
series as contemplated by Section 2.01, the Company may, at its option,
terminate certain of its obligations under this Indenture (“covenant
defeasance”) with respect to the Securities of a series if:

payments, specifically pledged as security for and dedicated solely to the
benefit of the Holders of Securities of such series, (i) money in the
currency in which payment of the Securities of such series is to be made in an
amount, or (ii) Government Obligations with respect to such series,
maturing as to principal and interest at such times and in such amounts as will
ensure the availability of money in the currency in which payment of the
Securities of such series is to be made in an amount or (iii) a combination
thereof, that is sufficient, in the opinion (in the case of clauses (ii) and
(iii)) of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, to pay
the principal of and premium (if any) and interest on all Securities of such
series on each date that such principal, premium (if any) or interest is due and

Company has delivered to the Trustee an Officers’ Certificate stating that all
conditions precedent to satisfaction and discharge of this Indenture with
respect to the Securities of such series have been complied with, and an Opinion
of Counsel to the same effect;

Company shall have delivered to the Trustee an Opinion of Counsel from a
nationally recognized counsel acceptable to the Trustee or a tax ruling to the
effect that the Holders will not recognize income, gain or loss for U.S. Federal
income tax purposes as a result of the Company’s exercise of its option under
this Section 8.01(b) and will be subject to U.S. Federal income tax on the same
amount and in the same manner and at the same times as would have been the case
if such option had not been exercised;

     

    (4)           the
Company has complied with any additional conditions specified pursuant to
Section 2.01 to be applicable to the discharge of Securities of such series
pursuant to this Section 8.01; and

     

    (5)           such
deposit and discharge shall not cause the Trustee to have a conflicting interest
as defined in TIA § 310(b).

     

    In such
event, this Indenture shall cease to be of further effect (except as set forth
in this paragraph), and the Trustee, on demand of the Company, shall execute

Indenture.  However, the Company’s obligations in Sections 2.05, 2.06,

Indenture with respect to the Securities of such series except for those
surviving obligations specified above.

     

    In order
to have money available on a payment date to pay principal of or premium (if
any) or interest on the Securities, the Government Obligations shall be payable
as to principal or interest on or before such payment date in such amounts as
will provide the necessary money.  Government Obligations shall not be
callable at the issuer’s option.

the Company has previously complied or is concurrently complying with Section
8.01(b) (other than any additional conditions specified pursuant to

with respect to Securities of a series, then, unless this Section 8.01(c) is
specified as not being applicable to Securities of such series as contemplated

Default or Event of Default under clauses (5) and (6) of Section 6.01 hereof
shall have occurred at any time during the period ending on the 91st day after
the date of deposit contemplated by Section 8.01(b) (it being understood that
this condition shall not be deemed satisfied until the expiration of such
period);

     

    (2)           unless
otherwise specified with respect to Securities of such series as contemplated by
Section 2.01, the Company has delivered to the Trustee an Opinion of Counsel
from a nationally recognized counsel acceptable to the Trustee to the effect
referred to in Section 8.01(b)(4) with respect to such legal defeasance, which
opinion is based on (i) a private ruling of the Internal Revenue Service
addressed to the Company, (ii) a published ruling of the Internal Revenue
Service pertaining to a comparable form of transaction or (iii) a change in the
applicable federal income tax law (including regulations) after the date of this
Indenture;

     

    (3)           the
Company has complied with any other conditions specified pursuant to Section
2.01 to be applicable to the legal defeasance of Securities of such series
pursuant to this Section 8.01(c); and

     

    (4)           the
Company has delivered to the Trustee a Company Request requesting such legal
defeasance of the Securities of such series and an Officers’ Certificate stating
that all conditions precedent with respect to such legal defeasance of the
Securities of such series have been complied with, together with an Opinion of
Counsel to the same effect.

     

    In such
event, the Company will be discharged from its obligations under this Indenture
and the Securities of such series to pay principal of, premium (if any) and
interest on and any Additional Amounts with respect to Securities of such
series, the Company’s obligations

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    under

entire indebtedness of the Company evidenced by such Securities shall be deemed
paid and discharged.

     

    (e)           If
and to the extent additional or alternative means of satisfaction, discharge or
defeasance of Securities of a series are specified to be applicable to such
series as contemplated by Section 2.01, the Company may terminate any or all of
its obligations under this Indenture with respect to Securities of a series and
any or all of its obligations under the Securities of such series if it fulfills
such other means of satisfaction and discharge as may be so specified, as
contemplated by Section 2.01, to be applicable to the Securities of such
series.

     

    (f)           If
Securities of any series subject to subsections (a), (b), (c) or (d) of this

to any optional redemption provisions or in accordance with any mandatory or
optional sinking fund provisions, the terms of the applicable trust arrangement

as are reasonably satisfactory to the Trustee for the giving of notice of
redemption by the Trustee in the name, and at the expense, of the
Company.

    The
Trustee or a trustee satisfactory to the Trustee and the Company shall hold in

hereof.  It shall apply the deposited money and the money from

the Paying Agent shall pay to the Company upon written request any money held by
them for the payment of principal, premium (if any), interest or any Additional
Amounts that remain unclaimed for two years after the date upon which such
payment shall have become due.  After payment to the Company, Holders
entitled to the money must look to the Company for payment as general creditors
unless an applicable abandoned property law designates another Person, and all
liability of the Trustee and the Paying Agent with respect to such money shall
cease.

Government Obligations in accordance with Section 8.01; provided, however, that if
the Company has made any payment of principal of, premium (if any) or interest
on or any Additional Amounts with respect to any Securities because of the
reinstatement of its obligations, the Company shall be subrogated to the rights

    The

than all series of Securities, stating that such covenants are expressly being
included solely for the benefit of such series), or to surrender any right or
power herein conferred upon the Company;

     

    (7)           to
add any additional Events of Default with respect to all or any series of the
Securities (and, if any Event of Default is applicable to less than all series
of Securities, specifying the series to which such Event of Default is
applicable);

     

    (8)           to
change or eliminate any of the provisions of this Indenture; provided that any such change

indenture that is adversely affected in any material respect by such change in
or elimination of such provision; provided, further, that any
change made solely to

     

    (9)

     

    conform
the provisions of this Indenture to the description of any Security in a
prospectus supplement pursuant to which such Securities were offered and sold
will not be deemed to adversely affect any Security of that series in any
material respect;

     

    (10)           to
establish the form or terms of Securities of any series as permitted by Section
2.01;

     

    (11)           to
supplement any of the provisions of this Indenture to such extent as shall be
necessary to permit or facilitate the defeasance and discharge of any series of

    (12)           to

change any of the provisions of this Indenture as shall be necessary to provide
for or facilitate the administration of the trusts hereunder by more than one
Trustee, pursuant to the requirements of Section 7.08.

     

    Upon the
request of the Company, accompanied by a Board Resolution, and upon receipt by
the Trustee of the documents described in Section 9.06, the Trustee shall,
subject to Section 9.06, join with the Company in the execution of any
supplemental indenture authorized or permitted by the terms of this Indenture
and make any further appropriate agreements and stipulations that may be therein
contained.

     

    
      	
              SECTION
      8.02

            	
              With Consent of
      Holders.

            

    

     

    Except as
provided below in this Section 9.02, the Company and the Trustee may amend or
supplement this Indenture with the written consent (including consents obtained
in connection with a tender offer or exchange offer for Securities of any one or
more series or all series or a solicitation of consents in respect of Securities
of any one or more series or all series, provided that in each case
such offer or solicitation is made to all Holders of then outstanding Securities
of each such series (but the terms of such offer or solicitation may vary from
series to series)) of the Holders of at least a majority in principal amount of
the then outstanding Securities of each series affected by such amendment or
supplement.

     

    Upon the
request of the Company, accompanied by a Board Resolution, and upon the filing
with the Trustee of evidence of the consent of the Holders as aforesaid, and
upon receipt by the Trustee of the documents described in Section 9.06, the
Trustee shall, subject to Section 9.06, join with the Company in the execution
of such amendment or supplemental indenture.

     

    It shall
not be necessary for the consent of the Holders under this Section 9.02 to
approve the particular form of any proposed amendment, supplement or waiver, but
it shall be sufficient if such consent approves the substance
thereof.

     

    The
Holders of a majority in principal amount of the then outstanding Securities of
one or more series may waive compliance in a particular instance by the Company
with any

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    provision
of this Indenture with respect to Securities of such series (including waivers
obtained in connection with a tender offer or exchange offer for Securities of
such series or a solicitation of consents in respect of Securities of such
series, provided that
in each case such offer or solicitation is made to all Holders of then
outstanding Securities of such series (but the terms of such offer or
solicitation may vary from series to series)).

     

    However,
without the consent of each Holder affected, an amendment, supplement or waiver
under this Section 9.02 may not:

     

    (1)           reduce
the amount of Securities whose Holders must consent to an amendment, supplement
or waiver;

     

    (2)           reduce
the rate of or change the time for payment of interest, including default
interest, on any Security;

     

    (3)           reduce
the principal of, any premium on or any mandatory sinking fund payment with
respect to, or change the Stated Maturity of, any Security or reduce the amount
of the principal of an Original Issue Discount Security that would be due and
payable upon a declaration of acceleration of the Maturity thereof pursuant to
Section 6.02;

     

    (4)           reduce
the premium, if any, payable upon the redemption of any Security or change the
time at which any Security may or shall be redeemed;

     

    (5)           change
any obligation of the Company to pay Additional Amounts with respect to any
Security;

     

    (6)           change
the coin or currency or currencies (including composite currencies) in which any
Security or any premium, interest or Additional Amounts with respect thereto are
payable;

     

    (7)           impair
the right to institute suit for the enforcement of any payment of principal of,
premium (if any) or interest on or any Additional Amounts with respect to any
Security pursuant to Sections 6.07 and 6.08, except as limited by Section
6.06;

     

    (8)           make
any change in the percentage of principal amount of Securities necessary to
waive compliance with certain provisions of this Indenture pursuant to
Section 6.04 or 6.07 or make any change in this sentence of Section 9.02;
or

     

    (9)           waive
a continuing Default or Event of Default in the payment of principal of, premium
(if any) or interest on or Additional Amounts with respect to the
Securities.

     

    A
supplemental indenture that changes or eliminates any covenant or other
provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other provision, shall be deemed not to affect the rights under this
Indenture of the Holders of Securities of any other series.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    The right
of any Holder to participate in any consent required or sought pursuant to any
provision of this Indenture (and the obligation of the Company to obtain any
such consent otherwise required from such Holder) may be subject to the
requirement that such Holder shall have been the Holder of record of any
Securities with respect to which such consent is required or sought as of a date
identified by the Company in a notice furnished to Holders in accordance with
the terms of this Indenture.

     

    After an
amendment, supplement or waiver under this Section 9.02 becomes effective, the
Company shall mail to the Holders of each Security affected thereby a notice
briefly describing the amendment, supplement or waiver.  Any failure
of the Company to mail such notice, or any defect therein, shall not, however,
in any way impair or affect the validity of any such amendment, supplement or
waiver.

     

    
      	
              SECTION
      8.03

            	
              Compliance with Trust
      Indenture Act.

            

    

     

    Every
amendment or supplement to this Indenture or the Securities shall comply in form
and substance with the TIA as then in effect.

     

    
      	
              SECTION
      8.04

            	
              Revocation and Effect of
      Consents.

            

    

     

    Until an
amendment, supplement or waiver becomes effective, a consent to it by a Holder
is a continuing consent by the Holder and every subsequent Holder of a Security
or portion of a Security that evidences the same debt as the consenting Holder’s
Security, even if notation of the consent is not made on any
Security.  However, any such Holder or subsequent Holder may revoke
the consent as to his or her Security or portion of a Security if the Trustee
receives written notice of revocation before a date and time therefor identified
by the Company in a notice furnished to such Holder in accordance with the terms
of this Indenture or, if no such date and time shall be identified, the date the
amendment, supplement or waiver becomes effective.  An amendment,
supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder.

     

    The
Company may, but shall not be obligated to, fix a record date (which need not
comply with TIA § 316(c)) for the purpose of determining the Holders entitled to
consent to any amendment, supplement or waiver or to take any other action under
this Indenture.  If a record date is fixed, then notwithstanding the
provisions of 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 consent to such amendment, supplement or waiver or
to revoke any consent previously given, whether or not such Persons continue to
be Holders after such record date.  No consent shall be valid or
effective for more than 90 days after such record date unless consents from
Holders of the principal amount of Securities required hereunder for such
amendment or waiver to be effective shall have also been given and not revoked
within such 90-day period.

     

    After an
amendment, supplement or waiver becomes effective, it shall bind every Holder,
unless it is of the type described in any of clauses (1) through (9) of Section
9.02 hereof.  In such case, the amendment, supplement or waiver shall
bind each Holder who has consented to it and every subsequent Holder that
evidences the same debt as the consenting Holder’s Security.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    Notation
on or Exchange of Securities.

     

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

     

    Securities
of any series authenticated and delivered after the execution of any amendment
or supplement may, and shall if required by the Trustee, bear a notation in form
approved by the Trustee as to any matter provided for in such amendment or
supplement.

              Trustee to Sign Amendments,
      etc.

            

    

     

    The Trustee shall sign any amendment or
supplement authorized pursuant to this Article if the amendment or supplement
does not adversely affect the rights, duties, liabilities or immunities of the
Trustee.  If it does, the Trustee may, but need not, sign
it.  In signing or refusing to sign such amendment or supplement, the
Trustee shall be entitled to receive, and, shall be fully protected in relying
upon in good faith, an Officers’ Certificate and an Opinion of Counsel provided
at the expense of the Company as conclusive evidence that such amendment or
supplement is authorized or permitted by this Indenture, that it is not
inconsistent herewith, and that it will be valid and binding upon the Company in
accordance with its terms.

2.02.                                           Book-Entry Provisions for Global
Notes

     

    .  i)
The Notes initially shall be issued in the form of one or more Global Notes
without interest coupons (i) registered in the name of Cede & Co., as
nominee of the Depositary, and (ii) delivered to the Trustee as custodian for
the Depositary.

     

    Members
of, or participants in, the Depositary (“Agent Members”) shall have no
rights under this Supplemental Indenture or the Original Indenture with respect
to any Global Note held on their behalf by the Depositary, or the Trustee as its
custodian, or under the Global Note, and Cede & Co., or such other Person
designated by the Depositary as its nominee, may be treated by the Company, the
Trustee and any agent of the Company or the Trustee as the absolute owner of the
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
governing the exercise of the rights of any Holder.

     

    (b)           Transfers
of Global Notes shall be limited to transfers in whole, but not in part, to the
Depositary, its successors or their respective
nominees.  Notwithstanding anything to the contrary in Section 2.17 of
the Original Indenture, interests of beneficial owners in a Global Note may be
transferred or exchanged, in whole or in part, for Physical Notes,
only:  (i) pursuant to the third paragraph of Section 2.17 of the
Original Indenture regarding the Depositary being unwilling, unable or
ineligible to continue in its capacity as Depositary for the Notes, including as
a result of ceasing to be registered as a clearing agency under the Exchange
Act, and a successor Depositary is not appointed within 60 days or (ii) if an
Event of Default with respect to the Notes has occurred and is continuing, in
each case in accordance with the rules and procedures of the
Depositary.  Other than as set forth in this Section 2.02(b), the
Notes shall remain in global form as Global Notes.

     

    (c)           In
connection with any transfer or exchange of a portion of the beneficial interest
in the Global Note to beneficial owners pursuant to Section 2.17 of the Original
Indenture, the Security Registrar shall (if one or more Physical Notes are to be
issued) reflect on its books and records the date and a decrease in the
principal amount of the Global Note in an amount equal to the principal amount
of the beneficial interest in the Global Note to be transferred, and the Company
shall execute, and the Trustee shall authenticate and deliver, one or more
Physical Notes of like tenor and amount in accordance with Section 2.17 of the
Original Indenture.

     

    (d)           In
connection with the transfer of the entire Global Note to beneficial owners
pursuant to Section 2.17 of the Original Indenture, the Global Note shall be
deemed to be

     

    (e)           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 the Global Note, an equal
aggregate principal amount of Physical Notes of authorized
denominations.

     

    (f)           The
Holder of Global Notes 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
Supplemental Indenture, Original Indenture or the Notes.

2.03.                                           CUSIP Numbers

     

    .  In
issuing the Notes, the Company may use “CUSIP” numbers (if then generally in
use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption
as a convenience to Holders of the Notes; provided that any such notice
may state that no representation is made as to the correctness of such numbers
as printed on the Notes 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
will promptly notify the Trustee of any change in the “CUSIP” numbers of the
Notes.

     

    SECTION
2.04.                                           Reporting
Requirement

     

    .  The
Company shall deliver to the Trustee within 15 days after the same is required
to be filed with the Commission, copies of the quarterly and annual reports and
of the information, documents and other reports, if any, that the Company is
required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act (giving effect to any grace period provided by Rule 12b-25 under
the Exchange Act), and the Company shall otherwise comply with the requirements
of Trust Indenture Act Section 314(a).  Any quarterly or annual report
or other information, document or other report that the Company files with the
Commission pursuant to Section 13 or 15(d) of the Exchange Act on the
Commission’s EDGAR system or any successor electronic filing system shall be
deemed to constitute delivery of such filing to the Trustee.  The
Trustee does not have the duty to review such information, documents or reports,
is not considered to have notice of the content of such information, documents
or reports and does not have a duty to verify the accuracy of such information,
documents or reports.

that if a Fundamental Change Purchase Date is after a Regular Record Date and on
or prior to the Interest Payment Date to which such Regular Record Date relates,
the interest payable in respect of such Interest Payment Date shall be payable
to the Holders of record as of the corresponding Regular Record Date and the

procedures for tendering interests in Global Notes, if the Notes are not
Physical Notes, in each case prior to the close of business on the Business Day
immediately preceding the Fundamental Change Purchase Date; and

     

    (ii)           delivery
of the Notes, in the case of Physical Notes, to the Paying Agent appointed by
the Company (together with all necessary endorsements for transfer), or
book-entry transfer of the Notes, in compliance with the procedures of the

    (ii)           the

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

     

    provided, however, that if such Notes
are in global form, the Fundamental Change Purchase Notice must also comply with
appropriate procedures of the Depositary.

     

    Notwithstanding
anything herein to the contrary, any Holder delivering to the Paying Agent the
Fundamental Change Purchase Notice contemplated by this Section 3.01 shall have
the right to withdraw, in whole or in part, such Fundamental Change Purchase

    Fundamental Change Company

occurrence of a Fundamental Change, the Company shall provide to all Holders of
the Notes, the Trustee and the Paying Agent (in the case of any Paying Agent
other than the Trustee) a notice (the “Fundamental Change Company
Notice”) of the occurrence of such Fundamental Change and of the purchase
right at the option of the Holders arising as a result thereof.  Such
notice shall be sent by first class mail or, in the case of any Global Notes, in
accordance with the procedures of the Depositary for providing
notices.  Simultaneously with providing such Fundamental Change
Company Notice, the Company shall publish a notice containing the information
included therein in a newspaper of general circulation in New York, New York or

applicable, that the Notes with respect to which a Fundamental Change Purchase
Notice has been delivered by a Holder may be converted only if the Holder
withdraws the Fundamental Change Purchase Notice in accordance with the
Indenture; and

     

    (xii)           the
procedures that Holders must follow to require the Company to purchase their
Notes.

     

    No
failure of the Company to give the foregoing notices and no defect therein shall
limit the purchase rights of the Holders of Notes or affect the validity of the
proceedings for the purchase of the Notes pursuant to this Section
3.01.

     

    (b)           No Payment During Events of
Default.  There shall be
no purchase of any Notes pursuant to this Section 3.01 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 the payment of the Fundamental Change Purchase Price
of the Notes).  The Paying Agent will promptly return to the
respective Holders thereof any Physical Notes held by it during the continuance
of an Event

     

    (c)           of
Default (other than an Event of Default that is cured by the payment of the
Fundamental Change Purchase Price with respect to the Notes) and shall deem
canceled any instructions for book-entry transfer of the Notes in compliance
with the procedures of the Depositary, in which case, upon such return and
cancelation, the Fundamental Change Purchase Notice with respect thereto shall
be deemed to have been withdrawn.

such Note (provided the
conditions in Section 3.01 hereof have been satisfied) and (y) the time of
delivery or book-entry transfer of such Note to the Paying Agent by the Holder
thereof in the manner required by Section 3.01 hereof.

of the Depositary.

Paying Agent will promptly return to the respective Holders thereof any Physical
Notes with respect to which a Fundamental Change Purchase Notice has been
withdrawn in compliance with the provisions of this Section 3.03.

Fundamental Change Purchase Notice has been tendered and not withdrawn in
accordance with this Supplemental Indenture on the Fundamental Change Purchase
Date, then as of such Fundamental Change Purchase Date, (a) such Notes will
cease to be outstanding and interest will cease to accrue thereon (whether or
not book-entry transfer of such Notes is made or such Notes have been delivered
to the Paying Agent) and (b) all other rights of the Holders in respect thereof
will terminate (other than the right to receive the Fundamental Change Purchase
Price and previously accrued and unpaid interest upon delivery or book-entry

requires in the case of Physical Notes, 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,

Exchange Act and (iii) otherwise comply with all federal and state securities
laws so as to permit the rights and obligations under Section 3.01 to be
exercised in the time and in the manner specified in Section 3.01, and shall not
be deemed to have breached its obligations under the Indenture by virtue of its
compliance with such securities laws or regulations.

    SECTION
4.01.                                           Right to Convert

     

    .  (a)
Subject to and upon compliance with the provisions of this Supplemental
Indenture, each Holder of Notes shall have the right, at such Holder’s option,
to convert the principal amount of any such Notes, or any portion of such
principal amount equal to $1,000 or a multiple of $1,000 thereof, at the
Conversion Rate in effect on the Conversion Date for such Notes, (x) prior to
the close of business on the Business Day immediately preceding March 15, 2014,
only upon satisfaction of one or more of the conditions described in clauses (i)
through (iv) below and (y) on or after March 15, 2014, at any time prior to the
close of business on the second Scheduled Trading Day immediately preceding June
15, 2014 irrespective of the conditions described in clauses (i) through (iv)
below:

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    Prior to
the close of business on the Business Day immediately preceding March 15, 2014,
a Holder of Notes may surrender all or a portion of its Notes for conversion
during any fiscal quarter (and only during such fiscal quarter) commencing after
September 30, 2009 if the Last Reported Sale Price of the Common Stock for at
least 20 Trading Days (whether or not consecutive) during the period of 30
consecutive Trading Days ending on the last Trading Day of the immediately
preceding fiscal quarter is greater than or equal to 130% of the applicable
Conversion Price in effect on each applicable Trading Day.  The
Company shall notify the Trustee and the Conversion Agent if the Notes become
convertible in accordance with this Section 4.01(a)(i).

     

    (i)           Prior
to the close of business on the Business Day immediately preceding March 15,
2014, a Holder of Notes may surrender its Notes for conversion during the five
Business Day period after any five consecutive Trading Day period (the “Measurement Period”) in which
the Trading Price per $1,000 principal amount of Notes, as determined following
a request by a Holder of Notes in accordance with the procedures set forth in
this Section 4.01(a)(ii), for each Trading Day of such period was less than 98%
of the product of the Last Reported Sale Price of the Common Stock and the
Conversion Rate on such Conversion Date (the “Trading Price
Condition”).  The Bid Solicitation Agent shall have no
obligation to determine the Trading Price of the Notes in accordance with this
Section 4.01(a)(ii) unless requested by the Company, and the Company shall have
no obligation to make such request unless a Holder of Notes provides the Company
with reasonable evidence that the Trading Price per $1,000 principal amount of
Notes would be less than 98% of the product of the Last Reported Sale Price of
the Common Stock and the applicable Conversion Rate.  The Company
shall instruct the Bid Solicitation Agent to determine (or, if the Company is
then acting as Bid Solicitation Agent, the Company shall determine) the Trading
Price of the Notes beginning on the next Trading Day promptly following the
receipt of such evidence and on each successive Trading Day until such Trading
Day on which the Trading Price per $1,000 principal amount of Notes is greater
than or equal to 98% of the product of the Last Reported Sale Price of the
Common Stock and the applicable Conversion Rate.  If the Company does
not so instruct the Bid Solicitation Agent to obtain (or, if the Company is then
acting as Bid Solicitation Agent, the Company does not obtain) bids when
required, the Trading Price per $1,000 principal amount of the Notes shall be
deemed to be less than 98% of the product of the Last Reported Sale Price of the
Common Stock and the applicable Conversion Rate on each day the Company fails to
do so.  If the Trading Price Condition has been met, the Company shall
so notify Holders, the Trustee and the Conversion Agent.  If, at any
time after the Trading Price Condition has been met, the Trading Price per
$1,000 principal amount of Notes is greater than or equal to 98% of the product
of the Last Reported Sale Price of the Common Stock and the Conversion Rate for
such date, the Company shall so notify Holders, the Trustee and the Conversion
Agent.

     

    (ii)           If
the Company elects to:

     

    (A)           issue
to all or substantially all holders of Common Stock rights or warrants entitling
them to purchase, for a period expiring within 45 days after the announcement
date of such issuance, shares of Common Stock at less than the average of the
Last Reported Sale Prices of a share of Common Stock for the 10

     

    (B)           consecutive
Trading Day period ending on the Trading Day immediately preceding the date of
announcement of such issuance; or

     

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

     

    then, in
each case, the Company shall notify the Holders of the Notes at least 45
Scheduled Trading Days prior to the Ex-Dividend Date for such issuance or
distribution.  Once the Company has given such notice, Holders may
surrender Notes for conversion at any time until the earlier of the close of
business on the Business Day immediately prior to such Ex-Dividend Date or the
Company’s announcement that such issuance or distribution will not take place,
even if the Notes are not otherwise convertible at such time.

     

    (iii)           If
a transaction or event that constitutes a Fundamental Change or a Make-Whole
Fundamental Change occurs, regardless of whether a Holder has the right to
require the Company to purchase the Notes pursuant to Article 3 hereof, or if
the Company is a party to a consolidation, merger, binding share exchange, or
sale, transfer or lease of all or substantially all of the Company’s assets, in
each case, pursuant to which the Common Stock would be converted into cash,
securities or other assets, Holders may surrender Notes for conversion at any
time from or after the date which is 45 Scheduled Trading Days prior to the
anticipated effective date of such transaction until 35 Trading Days after the
actual effective date of such transaction (or, if such transaction also
constitutes a Fundamental Change, until the related Fundamental Change Purchase
Date).  The Company shall notify Holders and the Trustee as promptly
as practicable following the date the Company publicly announces such
transaction, but in no event less than 45 Scheduled Trading Days prior to the
anticipated effective date of such transaction.

     

    Failure
by the Company to give any notice required by Section 4.01, or any defect
therein, shall not affect the legality or validity of the relevant transaction
or event.

     

    (b)           Notes
may not be converted after the close of business on the second Scheduled Trading

4.02.                                           Conversion
Procedures

     

    .  iii)  Each
Note shall be convertible at the office of the Conversion Agent and, if
applicable, in accordance with the procedures of the
Depositary.  

     

    (b)           In
order to exercise the conversion privilege with respect to any interest in a
Global Note, the Holder must comply with the Depositary’s procedures for
converting an interest in a Global Note and, if required, pay the funds required
by Section 4.03(e) and pay any taxes or duties if required pursuant to Section
4.08, and the Conversion Agent must be informed of the conversion in accordance
with the customary practice of the Depositary.  In order to exercise
the

     

    (c)           conversion
privilege with respect to any Physical Notes, the Holder of any such Notes to be
converted, in whole or in part, shall:

     

    (i)           complete
and manually sign the conversion notice provided on the back of the Note (the
“Conversion Notice”) or
a facsimile of the Conversion Notice;

     

    (ii)           deliver
the Conversion Notice, which is irrevocable, and the Note to the Conversion
Agent;

     

    (iii)           if
required, furnish appropriate endorsements and transfer documents,

     

    (iv)           make
any payment required under Section 4.03(e); and

     

    (v)           if
required, pay all transfer or similar taxes as set forth in Section
4.08.

     

    The date
on which the Holder satisfies all of the applicable requirements set forth above
is the “Conversion
Date.” The Conversion Agent will, as promptly as possible, and in any
event within two Business Days of the receipt thereof, provide the Company with
notice of any conversion by a Holder of the Notes.

     

    (d)           Each
Conversion Notice shall state the name or names (with address or addresses) in
which any certificate or certificates for shares of Common Stock which shall be
issuable on such conversion shall be issued.  All such Notes
surrendered for conversion shall, unless the shares issuable on conversion are
to be issued in the same name as the registration of such Notes, be duly
endorsed by, or be accompanied by instruments of transfer in form satisfactory
to the Company duly executed by, the Holder or his duly authorized
attorney.

     

    (e)           In
case any Notes of a denomination greater than $1,000 shall be surrendered for
partial conversion, the Company shall execute and the Trustee shall authenticate
and deliver to the Holder of the Notes so surrendered, without charge, new Notes
in authorized denominations in an aggregate principal amount equal to the
unconverted portion of the surrendered Notes.

     

    (f)           Each
conversion shall be deemed to have been effected as to any Notes (or portion
thereof) surrendered for conversion on the relevant Conversion Date, and with
respect to any shares of Common Stock that are issuable upon such conversion:
(i) if such conversion was subject to a Physical Settlement, the Person in whose
name the certificate or certificates for such shares of Common Stock will be
registered, shall become the holder of record of such shares as of the close of
business on the Conversion Date; and (ii) if such conversion was subject to a
Combination Settlement, the Person in whose name the certificate or certificates
for such shares of Common Stock will be registered, shall become the holder of
record of such shares as of the close of business on the last Trading Day of the
related Observation Period.

     

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

     

    (h)           Notwithstanding
the foregoing, a Note in respect of which a Holder has delivered a Fundamental
Change Purchase Notice exercising such Holder’s option to require the Company to
purchase such Note may be converted only if such notice of exercise is withdrawn
in accordance with Article 3 hereof prior to the close of business on the
Business Day prior to the relevant Fundamental Change Purchase
Date.

     

    SECTION
4.03.                                           Payments Upon
Conversion

     

    .  iv)
Except as provided in Section 4.06(b), upon any conversion of any Note, the
Company shall deliver to converting Holders, in respect of each $1,000 principal
amount of Notes being converted, at the Company’s election, in full satisfaction
of the Company’s conversion obligation, (1) shares of Common Stock, together
with cash in lieu of fractional shares, if any (a “Physical Settlement”), (2) a
cash payment without any delivery of shares of Common Stock (a “Cash Settlement”) or (3) a
combination of cash and shares of Common Stock, together with cash in lieu of
fractional shares, if any (a “Combination Settlement”), in
each case, as set forth below.

     

    For
conversions:

     

    (i)           that
occur prior to March 15, 2014, by the close of business on the Business Day
following the Conversion Date, the Company shall notify converting Holders of
the relevant Settlement Method and, if the Company elects a Combination
Settlement, the dollar amount of the conversion obligation (the “Cash Amount”) that will be
settled in cash;

     

    (ii)           that
occur on or after March 15, 2014, the Company shall notify all Holders of the
relevant Settlement Method and, if applicable, the related Cash Amount, by
notice on or prior to March 15, 2014 (which shall apply to all conversions on or
following March 15, 2014).

     

    If the
Company does not specify a Settlement Method as set forth above, then Physical
Settlement shall apply.  Any such notice of a Settlement Method may
not be revoked.

     

    (b)           If
the Company has elected or is deemed to have elected a Physical Settlement with
respect to any Notes tendered for conversion, the Company shall deliver, for
each $1,000 principal amount of Notes, a number of shares of Common Stock equal
to the Conversion Rate, together with cash in lieu of fractional
shares.  Except for conversions upon a Make-Whole Fundamental Change
as provided in Section 4.06, the Company shall deliver such shares of Common
Stock (1) on the third Business Day following the Conversion Date, in the case
of a Physical Settlement with respect to a Conversion Date on or prior to the
Business Day immediately preceding March 15, 2014, or (2) on the third Business
Day following the last day of the applicable Observation Period, in the case of
a Physical Settlement with respect to a Conversion Date on or after March 15,
2014.

     

    (c)           If
the Company has elected a Cash Settlement with respect to any Notes tendered for
conversion, the Company shall deliver, for each $1,000 principal amount of
Notes, a cash payment equal to the sum of the Daily Conversion Values for each
of the forty (40) consecutive Trading Days during the relevant Observation
Period.  Except for conversions upon a Make

     

    (d)           Whole
Fundamental Change as provided in Section 4.06, the Company shall make such
payment on the third Business Day following the last day of the applicable
Observation Period.

     

    (e)           If
the Company has elected a Combination Settlement with respect to any Notes
tendered for conversion, the Company shall deliver, for each $1,000 principal
amount of Notes, the sum of the Daily Settlement Amounts for each of the forty
(40) consecutive Trading Days during the relevant Observation
Period.

     

    The
“Daily Settlement
Amount” for each of the forty (40) consecutive Trading Days during the
Observation Period shall consist of:

     

    (i)           cash
in an amount equal to the lesser of (i) 2.5% of the cash amount specified by the
Company in the notice regarding the chosen Settlement Method (the “Daily Cash Amount”) and (ii)
the Daily Conversion Value on such Trading Day; and

     

    (ii)           if
the Daily Conversion Value on such Trading Day exceeds the Daily Cash Amount, a
number of shares of Common Stock (together with cash in lieu of any fractional
shares) equal to (i) the difference between such Daily Conversion Value and the
Daily Cash Amount, divided by (ii) the Daily VWAP on such Trading
Day.

     

    Except
for conversions upon a Make-Whole Fundamental Change as provided in Section
4.06, the Company shall deliver such cash and shares of Common Stock on the
third Business Day following the last day of the applicable Observation
Period.

     

    (f)           Upon
conversion of any Notes, Holders shall not receive any separate cash payment for
accrued and unpaid interest, except to the extent specified
below.  The Company’s delivery to the Holder of Common Stock, cash or
a combination of cash and Common Stock, as applicable, together with any cash
payment for any fractional share of Common Stock, into which a Note is
convertible shall be deemed to satisfy in full the Company’s obligation to pay
(i) the principal amount of the Notes so converted and (ii) accrued and unpaid
interest to, but not including, the Conversion Date.  As a result,
accrued and unpaid interest to, but not including, the Conversion Date shall be
deemed to be paid in full rather than cancelled, extinguished or
forfeited.  Notes surrendered for conversion during the period from
the close of business on any Regular Record Date to the opening of business on
the immediately following Interest Payment Date must be accompanied by funds
equal to the amount of interest payable on the Notes so converted; provided that no such payment
need be made (i) for conversions following the Regular Record Date immediately
preceding June 15, 2014, (ii) if the Company has specified a Fundamental Change
Purchase Date that is after a Regular Record Date and on or prior to the
corresponding Interest Payment Date, or (iii) to the extent of any overdue
interest, if any overdue interest exists at the time of conversion with respect
to such Note.

     

    (g)           The
Company shall not issue fractional shares of Common Stock upon conversion of
Notes.  If multiple Notes shall be surrendered for conversion at one
time by the same Holder, the number of full shares of Common Stock which shall
be issuable upon conversion shall be computed on the basis of the aggregate
principal amount of the Notes (or specified portions thereof to the extent
permitted hereby) so surrendered.  If any fractional share of Common
Stock

     

    (h)           would
be issuable upon the conversion of any Notes, the Company shall make payment
therefor in cash in lieu of fractional shares of Common Stock based
on:

     

    (i)           if
Physical Settlement applies, on the Last Reported Sale Price of the Common Stock
on the relevant Conversion Date, and

     

    (ii)           if
Combination Settlement applies, the Daily VWAP of the Common Stock on the final
Trading Day of the applicable Observation Period.

     

    (i)           Solely
for purposes of determining the payments and deliveries due upon conversion
under this Section 4.03, and notwithstanding the definition of “Trading Day”
contained in Section 1.02, “Trading Day” means a day on
which (i) there is no Market Disruption Event and (ii) trading in the Common
Stock generally occurs on The New York Stock Exchange or, if the Common Stock is
not then listed on The New York Stock Exchange, on the principal other United
States national or regional securities exchange on which the Common Stock is
then listed or, if the Common Stock is not then listed on a United States
national or regional securities exchange, on the principal other market on which
the Common Stock is then traded.  If the Common Stock (or other
security for which a Daily VWAP must be determined) is not so listed or traded,
“Trading Day” means a Business Day.

     

    (j)           Upon
surrender of Notes for conversion in connection with a Make-Whole Fundamental
Change, the Company shall deliver shares of Common Stock, cash or a combination
of cash and shares of Common Stock, as set forth above, at the increased
Conversion Rate as described in Section 4.06.

     

    SECTION
4.04.                                           Adjustment of Conversion
Rate

     

    .  The
Conversion Rate shall be adjusted from time to time by the Company if any of the
following events occurs, except that the Company will not make any adjustment to
the Conversion Rate if Holders of Notes participate, as a result of holding the
Notes, in any of the transactions described under Section 4.04(a) (but only with
respect to stock dividends or distributions), Section 4.04(b), Section 4.04(c),
and Section 4.04(d), at the same time as holders of the Common Stock
participate, without having to convert their Notes, as if such Holders held a
number of shares of Common Stock equal to the Conversion Rate in effect for each
$1,000 principal amount of such Notes immediately prior to the Ex-Dividend Date
for such event.

     

    (a)           If
the Company, at any time or from time to time while any of the Notes are
outstanding, exclusively issues shares of its Common Stock as a dividend or
distribution on shares of Common Stock, or if the Company effects a share split
or share combination, then the Conversion Rate shall be adjusted based on the
following formula:

     

    
      	
              CR1

            	
              =

            	
              CR0

            	
              x

            	
              
                OS1

              

            
	
              OS0

            

    

    

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    here

     

    
      	
              CR0

            	
              =

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

            
	
              CR1

            	
              =

            	
              The
      Conversion Rate in effect immediately after the opening of business on
      such Ex-Dividend Date or such effective date;

            
	
              OS0

            	
              =

            	
              The
      number of shares of Common Stock outstanding immediately prior to the
      opening of business on such Ex-Dividend Date or such effective date;
      and

            
	
              OS1

            	
              =

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

            

    

    Such
adjustment shall become effective immediately after the opening of business on
the Ex-Dividend Date for such dividend or distribution or the effective date for
such share split or share combination.  If any dividend or
distribution of the type described in this Section 4.04(a) is declared but not
so paid or made, the Conversion Rate shall again be adjusted to the Conversion
Rate which would then be in effect if such dividend or distribution had not been
declared.

     

    (b)           If
the Company, at any time or from time to time while any of the Notes are
outstanding, issues to all or substantially all holders of the Common Stock any
rights or warrants entitling them for a period of not more than 45 calendar days
after the announcement date of such issuance to subscribe for or purchase shares
of the Common Stock at a price per share less than the average of the Last
Reported Sale Prices of the Common Stock for the 10 consecutive Trading Day
period ending on the Trading Day immediately preceding the date of announcement
of such issuance, the Conversion Rate shall be adjusted based on the following
formula:

     

    
      	
              CR1

            	
              =

            	
              CR0

            	
              x

            	
              
                OS0 +
      X

              

            
	
              OS0 +
      Y

            

    

     

    

    where

     

    
      	
              CR0

            	
              =

            	
              The
      Conversion Rate in effect immediately prior to the opening of business on
      the Ex-Dividend Date for such issuance;

            
	
              CR1

            	
              =

            	
              The
      Conversion Rate in effect immediately after the opening of business on
      such Ex-Dividend Date;

            
	
              OS0

            	
              =

            	
              The
      number of shares of Common Stock outstanding immediately prior to the
      opening of business on such Ex-Dividend Date;

            
	
              X

            	
              =

            	
              The
      total number of shares of Common Stock issuable pursuant to such rights or
      warrants; and

            
	
              Y

            	
              =

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

            

    

     

    Such
adjustment shall become effective immediately after the opening of business on
the Ex-Dividend Date for such issuance.  To the extent such rights or
warrants are not exercised prior to their expiration or termination, the
Conversion Rate shall be readjusted to the Conversion Rate which would be in
effect had the adjustments made upon the issuance of such rights or warrants
been made on the basis of the delivery of only the number of shares of Common
Stock actually delivered.  In the event that such rights or warrants
are not so issued, the Conversion Rate shall again be adjusted to be the
Conversion Rate which would then be in effect if the date fixed for the
determination of shareholders entitled to receive such rights or warrants had
not been fixed.  For the purposes of this Section 4.04(b), in
determining whether any rights or warrants entitle the holders to subscribe for
or purchase shares of Common Stock at less than the average of the Last Reported
Sale Prices of Common Stock for the 10 consecutive Trading Day period ending on
the Trading Day immediately preceding the date of announcement of such issuance,
and in determining the aggregate exercise price payable for such shares of
Common Stock, there shall be taken into account any consideration received by
the Company for such rights or warrants and any amount payable on the exercise
thereof, with the value of such consideration, if other than cash, as shall be
determined by the Board of Directors.

     

    (c)           If
the Company, at any time or from time to time while the Notes are outstanding,
distributes shares of any class of capital stock of the Company, evidences of
its indebtedness, other assets or property of the Company or rights or warrants
to acquire the Company’s capital stock or other securities to all or
substantially all holders of its Common Stock, excluding:

     

    (i)           dividends
or distributions and rights or warrants as to which an adjustment was effected
pursuant to Section 4.04(a) or Section 4.04(b);

     

    (ii)           dividends
or distributions paid exclusively in cash (as set forth below in Section
4.04(d)); and

     

    (iii)           Spin-Offs
to which the provisions set forth below in this Section 4.04(c) shall
apply;

     

    then the
Conversion Rate shall be adjusted based on the following formula:

     

    
      	
              CR1

            	
              =

            	
              CR0

            	
              x

            	
              
                SP0

              

            
	
              SP0 -
      FMV

            

    

     

    

    where

     

    
      	
              CR0

            	
              =

            	
              the
      Conversion Rate in effect immediately prior to the opening of business on
      the Ex-Dividend Date for such distribution;

            
	
              CR1

            	
              =

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

            
	
              SP0

            	
              =

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

            
	
              FMV

            	
              =

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

            

    

     

    Such
adjustment shall become effective immediately after the opening of business on
the Ex-Dividend Date for such distribution.  If the Board of Directors
determines the “FMV” (as defined above) of any distribution for purposes of this
Section 4.04(c) by reference to the actual or when issued trading market for any
securities, it must in doing so consider the prices in such market over the same
period used in computing the average of the Last Reported Sale Prices of the
Common Stock.  Notwithstanding the foregoing, if “FMV” (as defined
above) is equal to or greater than “SP0” (as
defined above), in lieu of the foregoing adjustment, each Holder of Notes shall
receive, at the same time and upon the same terms as holders of the Common
Stock, the amount and kind of securities, assets and property such Holder would
have received as if such Holder owned a number of shares of Common Stock equal
to, for each $1,000 principal amount of Notes, the Conversion Rate in effect on
the Record Date for the distribution of the securities, assets or
property.

     

    With
respect to an adjustment pursuant to this Section 4.04(c) where there has been a
payment of a dividend or other distribution on the Common Stock of shares of
capital stock of any class or series, or similar equity interest, of or relating
to a Subsidiary or other business unit and such dividend or distribution is
listed for trading on a securities exchange (a “Spin-Off”), the Conversion
Rate shall be increased based on the following formula:

     

    
      	
              CR1

            	
              =

            	
              CR0

      equity interest distributed to holders of Common Stock applicable to one
      share of Common Stock (determined for purposes of the definition of Last
      Reported Sale Price as if such capital stock or similar equity interest
      were the Common Stock) over the first 10 consecutive Trading Day period

    The
adjustment to the Conversion Rate under the preceding paragraph will occur on
the last day of the Valuation Period; provided that in respect of
any conversion during the Valuation Period, references above to 10 Trading Days
shall be deemed replaced with such lesser number of Trading Days as have elapsed
between the Ex-Dividend Date of such Spin-Off and the Conversion Date in
determining the applicable Conversion Rate.

     

    For the
purposes of this Section 4.04(c) (and subject in all respects to Section 4.12),
rights or warrants distributed by the Company to all holders of its Common Stock
entitling them to subscribe for or purchase shares of the Company’s capital
stock (either initially or under certain circumstances), which rights or
warrants, until the occurrence of a specified event or events (a “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 be deemed not to have been distributed
for purposes of this Section 4.04(c), (and no adjustment to the Conversion Rate
under this Section 4.04(c) will be required) until the occurrence of the
earliest Trigger Event, whereupon such rights and warrants shall be deemed to
have been distributed and an appropriate adjustment (if any is required) to the
Conversion Rate shall be made under this Section 4.04(c).  If any such
right or warrant, including any such existing rights or warrants distributed
prior to the date of this Supplemental 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 Ex-Dividend Date of such deemed distribution (in which case the
original rights or warrants shall be deemed to terminate and expire on such date
without exercise by any of the holders).  In addition, in the event of
any distribution or deemed distribution of rights or warrants, or any Trigger
Event or other event (of the type described in the preceding sentence) with
respect thereto that was counted for purposes of calculating a distribution
amount for which an adjustment to the Conversion Rate under this Section 4.04(c)
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, upon such
final redemption or repurchase (x) the Conversion Rate shall be readjusted as if
such rights or warrants had not been issued and (y) the Conversion Rate shall
then again be readjusted to give effect to such distribution, deemed
distribution or Trigger Event, as the case may be, as though it were a cash
distribution, equal to the per share redemption or purchase price received by
holders of Common Stock with respect to such rights or warrants (assuming each
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 Conversion Rate shall be readjusted as if such rights and
warrants had not been issued.

     

    For the
purposes of this Section 4.04(c) and subsections (a) and (b) of this Section
4.04, any dividend or distribution to which this Section 4.04(c) applies which
also includes one or both of:

     

    
      	
               
      

            	
              (A)

            	
              a
      dividend or distribution of shares of Common Stock to which Section
      4.04(a) applies (the “Clause A Distribution”);
      and

            

    

     

    
      	
               
      

            	
              (B)

            	
              a
      dividend or distribution of rights or warrants to which Section 4.04(b)
      applies (the “Clause B
      Distribution”),

            

    

     

    then (1)
such dividend or distribution, other than the Clause A Distribution and the
Clause B Distribution, shall be deemed to be a dividend or distribution to which
this Section 4.04(c) applies (the “Clause C Distribution”) and
any Conversion Rate adjustment required by this Section 4.04(c) with respect
thereto shall then be made, and (2) the Clause A Distribution and Clause B
Distribution shall be deemed to immediately follow the Clause C Distribution and
any Conversion Rate adjustment required by Section 4.04(a) and Section 4.04(b)
with respect thereto shall then be made, except that, if determined by the
Company, (I) the “Ex-Dividend Date” of the Clause A Distribution and the Clause
B Distribution shall be deemed to be the Ex-Dividend Date of the Clause C
Distribution and (II) any shares of Common Stock included in the Clause A
Distribution or Clause B Distribution shall be deemed not to be “outstanding
immediately prior to the opening of business on such Ex-Dividend Date or such
effective date” within the meaning of Section 4.04(a) or “outstanding
immediately prior to the opening of business on such Ex-Dividend Date” within
the meaning of Section 4.04(b).

     

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

     

    
      	
              CR1

            	
              =

            	
              CR0

            	
              x

            	
              
                SP0

              

            
	
              SP0 –
      C

            

    

     

    

    where

     

    
      	
              CR0

            	
              =

            	
              The
      Conversion Rate in effect immediately prior to the opening of business on
      the Ex-Dividend Date for such dividend or distribution;

            
	
              CR1

            	
              =

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

            
	
              SP0

            	
              =

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

            
	
              C

            	
              =

            	
              The
      amount in cash per share the Company distributes to holders of the Common
      Stock.

            

    

     

    In the
case of an adjustment pursuant to this Section 4.04(d), such adjustment shall
become effective immediately after the opening of business on the Ex-Dividend
Date for the relevant dividend or distribution.  If the portion of the
cash so distributed applicable to one share of the Common Stock is equal to or
greater than the Last Reported Sale Price of a share of Common Stock on the
Trading Day immediately preceding the Ex-Dividend Date for such dividend or
distribution, in lieu of the adjustment set forth above, adequate provision
shall be made so that each Holder of Notes shall have the right to receive on
the date on which such cash dividend or distribution is distributed to holders
of Common Stock, for each $1,000 principal amount of Notes, the amount of cash
such Holder would have received had such Holder owned a number of shares of
Common Stock equal to the Conversion Rate in effect immediately prior to the
Ex-Dividend Date for such distribution.

     

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

     

    
      	
              CR1

            	
              =

            	
              CR0

            	
              x

            	
              
                AC
      + (SP1 x
      OS1)

              

            
	
              OS0 x
      SP1

            

    

     

    

    where

     

    
      	
              CR0

            	
              =

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

            
	
              CR1

            	
              =

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

            
	
              AC

            	
              =

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

            
	
              OS0

            	
              =

            	
              the
      number of shares of Common Stock outstanding immediately prior to the date
      such tender or exchange offer expires;

            
	
              OS1

            	
              =

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

            
	
              SP1

            	
              =

            	
              the
      average of the Last Reported Sale Prices of the Common Stock over the 10
      consecutive Trading Day period commencing on the Trading Day next
      succeeding the date such tender or exchange offer
  expires.

            

    

     

    The
adjustment to the Conversion Rate under this Section 4.04(e) shall occur as of
the close of business on the tenth Trading Day immediately following, and
including, the Trading Day next succeeding the date such tender or exchange
offer expires; provided
that in respect of any conversion within 10 Trading Days immediately following,
and including, the expiration date of any tender or exchange offer, references
with respect to 10 Trading Days shall be deemed replaced with such lesser number
of Trading Days as have elapsed between the expiration date of such tender or
exchange offer and the Conversion Date in determining the applicable Conversion
Rate.

     

    (f)           The
Company from time to time may increase the Conversion Rate by any amount for any
period of time of at least 20 Business Days, so long as the increase is
irrevocable during the period and the Board of Directors shall have made a
determination that such increase would be in the best interests of the Company,
which determination shall be conclusive.  Whenever the Conversion Rate
is increased pursuant to this Section 4.04(f), the Company shall mail to Holders
of record of the Notes a notice of the increase at least one day prior to the
date the increased Conversion Rate takes effect, and such notice shall state the
increased Conversion Rate and the period during which it will be in
effect.

     

    (g)           The
Company may (but shall not be required to) increase the Conversion Rate, in
addition to any adjustments pursuant to Section 4.04(a), 4.04(b), 4.04(c),
4.04(d), 4.04(e) or 4.04(f), if the Board of Directors considers such increase
to be advisable to avoid or diminish any income tax to holders of Common Stock
or rights to purchase Common Stock in connection with a dividend or distribution
of shares (or rights to acquire shares) or similar event.

     

    (h)           All
calculations under this Article 4 shall be made by the Company and shall be made
to the nearest cent (including, in the case of any adjustment to the Conversion
Rate, the resulting adjustment to the Conversion Price) or to the nearest one
ten-thousandth of a share.  No adjustment shall be required to be made
for the Company’s issuance of Common Stock or any securities convertible into or
exchangeable for shares of Common Stock or rights to purchase shares of Common
Stock or such convertible or exchangeable securities, other than as provided in
this Section 4.04 and in Section 4.11 hereof.

     

    (i)           Whenever
the Conversion Rate is adjusted as herein provided, the Company shall promptly
file with the Trustee and any Conversion Agent an Officers’ Certificate setting
forth the Conversion Rate after such adjustment and setting forth a brief
statement of the facts requiring such adjustment.  Unless and until a
Responsible Officer of the Trustee shall have received such Officers’
Certificate, the Trustee shall not be deemed to have knowledge of any adjustment
of the Conversion Rate and may assume without inquiry that the last Conversion
Rate of which it has knowledge is still in effect.  Promptly after
delivery of such certificate, the Company shall prepare a notice of such
adjustment of the Conversion Rate setting forth the adjusted Conversion Rate and
the date on which each adjustment becomes effective and shall mail such notice
of such adjustment of the Conversion Rate to each Holder of the
Notes.  Failure to deliver such notice shall not affect the legality
or validity of any such adjustment.

     

    (j)           For
purposes of this Section 4.04, the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Company so long
as the Company does not pay any dividend or make any distribution on shares of
Common Stock held in the treasury of the Company, but shall include shares
issuable in respect of scrip certificates issued in lieu of fractions of shares
of Common Stock.

     

    (k)           Notwithstanding
the foregoing, if the application of the foregoing formulas set forth in this
Section 4.04 would result in a decrease in the Conversion Rate, no adjustment to
the Conversion Rate shall be made (other than as a result of a share
combination).

     

    (l)           Notwithstanding
anything to the contrary in this Article 4, no adjustment to the Conversion Rate
shall be made:

     

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

     

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

     

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

     

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

     

    (v)           for
accrued and unpaid interest on the Notes.

     

    (m)           The
Company shall not be required to make an adjustment in the Conversion Rate
unless the adjustment would require a change of at least 1% in the Conversion
Rate.  However, the Company will carry forward any adjustments that
are less than 1% of the Conversion Rate and make such carried forward
adjustment, regardless of whether the aggregate adjustment is less than 1%, (i)
upon any Conversion Date of Notes and (ii) on each Trading Day of any
Observation Period.

     

    (n)           If
a Conversion Rate adjustment becomes effective on any Ex-Dividend Date as
described above, and a Holder that has converted its Notes on or after such
Ex-Dividend Date and on or prior to the related Regular Record Date would be
treated as the record holder of shares of Common Stock as of the related
Conversion Date as set forth in Section 4.02(e) based on an adjusted Conversion
Rate for such Ex-Dividend Date, then, notwithstanding the Conversion Rate
adjustment provisions above, the Conversion Rate adjustment relating to such
Ex-Dividend Date shall not be made for such converting
Holder.  Instead, such Holder shall be deemed to be the record owner
of shares of Common Stock on an unadjusted basis on such Conversion Date and
participate in the related dividend, distribution or other event giving rise to
such adjustment.

     

    (o)

     

    Certain
Other Adjustments

     

    .  Whenever
a provision of this Supplemental Indenture requires the calculation of Last
Reported Sale Prices or Daily VWAP over a span of multiple days, the Board of
Directors will make appropriate adjustments to such Last Reported Sale Prices or
Daily VWAP, the Conversion Rate, or the amount due upon conversion to account
for any adjustment to the Conversion Rate that becomes effective, or any event
requiring an adjustment to the Conversion Rate where the Ex-Dividend Date of the
event occurs, at any time during the period from which such Last Reported Sale
Prices or Daily VWAP are to be calculated.

     

    SECTION
4.05.                                           Adjustments Upon Certain Fundamental
Changes

     

    .  v)
If a Make-Whole Fundamental Change occurs and a Holder elects to convert its
Notes in connection with such Make-Whole Fundamental Change, the Company shall,
under the circumstances described below, increase the Conversion Rate for the
Notes so surrendered for conversion by a number of additional shares of Common
Stock (the “Additional
Shares”) as described below.  A conversion of Notes shall be
deemed for these purposes to be “in connection with” such Make-Whole Fundamental
Change if the notice of conversion of the Notes is received by the Conversion
Agent from, and including, the Effective Date of the Make-Whole Fundamental
Change up to, and including, the Business Day immediately prior to the related
Fundamental Change Purchase Date (or, in the case of an event that would have
been a Fundamental Change but for the proviso in clause (2) of the definition
thereof, the 35th Trading Day immediately following the Effective Date of such
Make-Whole Fundamental Change).

     

    (b)           Upon
surrender of Notes for conversion in connection with a Make-Whole Fundamental
Change, the Company shall have the right to deliver, in lieu of shares of Common
Stock, including the Additional Shares, cash or a combination of cash and shares
of Common Stock as provided under Section 4.03(a); provided, however, that if,
at the effective time of a Make-Whole Fundamental Change, the Reference Property
is comprised entirely of cash, then, for any conversion of Notes following the
Effective Date of such Make-Whole Fundamental Change, the amounts deliverable by
the Company shall be calculated based solely on the Stock Price for the
Make-Whole Fundamental Change and shall be deemed to be an amount equal to the
Conversion Rate (including any adjustment for Additional Shares) multiplied by
such Stock Price. In such event, the amounts deliverable by the Company shall be
determined and paid to holders in cash on the third Business Day following the
Conversion Date.

     

    (c)           The
number of Additional Shares, if any, by which the Conversion Rate will be
increased will be determined by reference to the table attached as Schedule A
hereto, based on the date on which the Make-Whole Fundamental Change occurs or
becomes effective (the “Effective Date”) and the
price (the “Stock
Price”) paid (or deemed paid) per share of the Common Stock in the
Make-Whole Fundamental Change.  If the holders of the Common Stock
receive only cash in a Make-Whole Fundamental Change described in clause (2) of
the definition of Fundamental Change, the Stock Price shall be the cash amount
paid per share.  Otherwise, the Stock Price shall be the average of
the Last Reported Sale Prices of the Common Stock over the ten Trading-Day
period ending on, and including, the Trading Day preceding the Effective Date of
the Make-Whole Fundamental Change.

     

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

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    If the
Stock Price is between two Stock Prices in the table or the Effective Date is
between two Effective Dates in the table, the number of Additional Shares shall
be determined by a straight-line interpolation between the number of Additional
Shares set forth for the higher and lower Stock Prices and the earlier and later
Effective Dates, as applicable, based on a 365-day year.

     

    (i)           If
the Stock Price is greater than $107.50 per share (subject to adjustment in the
same manner as the Stock Prices set forth in the column headings of the table in
Schedule A pursuant to subsection (d) below), no Additional Shares shall be
added to the Conversion Rate.

     

    (ii)           If
the Stock Price is less than $18.67 per share (subject to adjustments in the
same manner as the Stock Prices set forth in the column headings of the table in
Schedule A pursuant to subsection (d) below), no Additional Shares shall be
added to the Conversion Rate.

     

    Notwithstanding
the foregoing, in no event shall the Conversion Rate exceed 53.5619 shares of
Common Stock per $1,000 principal amount of Notes, subject to adjustments in the
same manner as the Conversion Rate as set forth in Section 4.04.

     

    (d)           The
Stock Prices set forth in the column headings of the table in Schedule A hereto
shall be adjusted as of any date on which the Conversion Rate of the Notes is
otherwise adjusted.  The adjusted Stock Prices shall equal the Stock
Prices applicable immediately prior to such adjustment, multiplied by a
fraction, the numerator of which is the Conversion Rate immediately prior to
such adjustment giving rise to the Stock Price adjustment and the denominator of
which is the Conversion Rate as so adjusted.  The number of Additional
Shares set forth in such table shall be adjusted in the same manner as the
Conversion Rate as set forth in Section 4.04.

     

    (e)           The
Company shall notify the Holders of Notes of the Effective Date of any
Make-Whole Fundamental Change and issue a press release announcing such
Effective Date no later than five Business Days after such Effective
Date.

     

    SECTION
4.06.                                           Effect of Recapitalization,
Reclassification, Consolidation, Merger or Sale.

     

    (a)           If
any of the following events occur:

     

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

     

    (ii)           a
consolidation, merger or combination involving the Company; or

     

    (iii)           a
sale, lease or other transfer to a third party of the consolidated assets of the
Company and its Subsidiaries substantially as an entirety, or any statutory
share exchange;

     

    (iv)           in
each case as a result of which the Common Stock would be converted into, or
exchanged for, or would be reclassified or changed into, stock, other
securities, other property or assets (including cash or any combination thereof)
(any such event, a “Merger
Event”), then at the effective time of such Merger Event, the Company or
the successor or purchasing Person, as the case may be, shall execute with the
Trustee a supplemental indenture (which shall comply with the Trust Indenture
Act as in force at the date of execution of such supplemental indenture)
providing that at and after the effective time of such Merger Event, the right
to convert a Note will be changed into a right to convert such Note as set forth
in this Indenture into the kind and amount of shares of stock, other securities
or other property or assets (including cash or any combination thereof) that a
holder of a number of shares of Common Stock equal to the Conversation Rate
prior to such Merger Event would have owned or been entitled to receive (the
“Reference Property”,
with each “unit of Reference
Property” meaning the type and amount of Reference Property that a holder
of one share of Common Stock is entitled to receive) upon such Merger Event;
provided, however, that at and after the effective time of the Merger Event the
conversion obligation shall be calculated and settled in accordance with Section
4.03 such that (i) the amount payable in cash upon conversion of the Notes as
set forth under Section 4.03 will continue to be payable in cash, (ii) the
number of shares of Common Stock (if the Company elects Physical Settlement or
Combination Settlement) deliverable upon conversion of the Notes under Section
4.03 will be instead deliverable in the amount and type of Reference Property
that a holder of that number of shares of Common Stock would have been entitled
to receive in such Merger Event and (iii) the Daily VWAP will be calculated
based on the value of a unit of Reference Property.

     

    If, as a
result of  the Merger Event, each share of Common Stock is converted
into the right to receive more than a single type of consideration (determined
based in part upon any form of stockholder election), then (x) the Reference
Property into which the Notes will be convertible will be deemed to be the
weighted average of the types and amounts of consideration received by the
holders of Common Stock that affirmatively make such an election, and (y) the
unit of Reference Property for purposes of the foregoing sentence shall refer to
the consideration referred to in clause (x) attributable to one share of Common
Stock.

     

    The
Company shall not become a party to any such Merger Event unless its terms are
consistent with this Section 4.07.  Such supplemental indenture shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 4 in the judgment of
the Board of Directors or the board of directors of the successor
Person.  If, in the case of any such recapitalization,
reclassification, change, consolidation, merger, combination, sale, lease, other
transfer or statutory share exchange, the Reference Property receivable
thereupon by a holder of Common Stock includes shares of stock, securities or
other property or assets (including cash or any combination thereof) of a Person
other than the successor or purchasing Person, as the case may be, in such
reorganization, reclassification, change, consolidation, merger, combination,
sale, lease, other transfer or statutory share exchange, then such supplemental
indenture shall also be executed by such other Person.

     

    (b)           The
Company shall cause notice of the execution of such supplemental indenture to be
mailed to each Holder, at the address of such Holder as it appears on the
register of the

     

    (c)           Notes
maintained by the Registrar, within 20 calendar days after execution
thereof.  Failure to deliver such notice shall not affect the legality
or validity of such supplemental indenture.  The above provisions of
this Section 4.07 shall similarly apply to successive reclassifications,
changes, consolidations, mergers, combinations, sales and
conveyances.  If this Section 4.07 applies to any Merger Event,
Section 4.04 shall not apply.

     

    SECTION
4.07.                                           Taxes on Shares
Issued

     

    .  The
Company will pay any documentary, stamp or similar issue or transfer tax due on
the issue or delivery of shares of Common Stock on conversion of Notes pursuant
hereto; provided, however, that if such documentary, stamp or similar issue or
transfer tax is due because the Holder of such Notes has requested that shares
of Common Stock be issued in a name other than that of the Holder of the Notes
converted, then such taxes will be paid by the Holder, and the Company shall not
be required to issue or deliver any stock certificate evidencing such shares
unless and until the Holder shall have paid to the Company the amount of such
tax or shall have established to the satisfaction of the Company that such tax
has been paid.

     

    SECTION
4.08.                                           Reservation of Shares; Shares to be
Fully Paid; Compliance With Governmental Requirements; Listing of Common
Stock

     

    .  The
Company shall reserve, out of its authorized but unissued shares or shares held
in treasury, sufficient shares of Common Stock to satisfy conversion of the
Notes from time to time as such Notes are presented for conversion (assuming
that, at the time of the computation of such number of shares or securities, all
such Notes would be converted by a single Holder and that Physical Settlement
would apply).

     

    The
Company covenants that all shares of Common Stock that may be issued upon
conversion of Notes shall be newly issued shares or treasury shares, shall be
duly authorized, validly issued, fully paid and non-assessable and shall be free
from preemptive rights and free from any tax, lien or charge (other than those
created by the Holder).

     

    The
Company shall list or cause to have quoted any shares of Common Stock to be
issued upon conversion of Notes on each national securities exchange or
over-the-counter or other domestic market on which the Common Stock is then
listed or quoted.

     

    SECTION
4.09.                                           Responsibility of
Trustee

     

    .  The
Trustee and any Conversion Agent shall not at any time be under any duty or
responsibility to any Holder of Notes to determine or calculate the Conversion
Rate, to determine whether any facts exist which may require any adjustment of
the Conversion Rate, or to confirm the accuracy of any such adjustment when made
or the appropriateness of the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same.  The Trustee
and any other Conversion Agent shall not be accountable with respect to the
validity or value (or the kind or amount) of any shares of Common Stock or of
any other securities or property that may at any time be issued or delivered
upon the conversion of any Notes; and the Trustee and the Conversion Agent make
no representations with respect thereto.  Neither the Trustee nor any
Conversion Agent shall be responsible for any failure of the Company to issue,
transfer or deliver any shares of Common Stock or stock certificates or other
securities or property or cash upon the surrender of any Notes for the purpose
of conversion or to comply with any of the duties, responsibilities or covenants
of the Company contained in this Article 4.  The rights, privileges,
protections, immunities and benefits given to the Trustee, including without
limitation its right to be compensated,

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    reimbursed,
and indemnified, are extended to, and shall be enforceable by, the Trustee in
each of its capacities hereunder, including its capacity as Conversion Agent and
if it is so appointed by the Company and accepts such appointment, as Bid
Solicitation Agent.

     

    SECTION
4.10.                                           Notice to Holders Prior to Certain
Actions

     

    .  In
case:

     

    (a)           the
Company shall declare a dividend (or any other distribution) on its Common Stock
that would require an adjustment in the Conversion Rate pursuant to Section
4.04; or

     

    (b)           the
Company shall authorize the granting to the holders of all or substantially all
of its Common Stock of rights or warrants to subscribe for or purchase any share
of any class or any other rights or warrants that would require an adjustment in
the Conversion Rate pursuant to Section 4.04 or Section 4.12 hereof;
or

     

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

     

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

     

    then, in
each case (unless notice of such event is otherwise required pursuant to another
provision of this Supplemental Indenture), the Company shall cause to be filed
with the Trustee and the Conversion Agent and to be mailed to each Holder of
Notes at such Holder’s address appearing on a list of Holders of Notes, which
the Company shall provide to the Trustee, as promptly as practicable but in any
event at least 10 calendar days prior to the applicable date hereinafter
specified, a notice stating (x) the date on which a record is to be taken for
the purpose of such dividend (or any other distribution) or rights or warrants,
or, if a record is not to be taken, the date as of which the holders of Common
Stock of record to be entitled to such dividend, distribution or rights or
warrants are to be determined, or (y) the date on which such reclassification,
reorganization, consolidation, merger, sale, lease, transfer, dissolution,
liquidation or winding up is expected to become effective or occur, and the date
as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their Common Stock for securities or other property
deliverable upon such reclassification, reorganization, consolidation, merger,
sale, transfer, dissolution, liquidation or winding up.  Failure to
give such notice, or any defect therein, shall not affect the legality or
validity of such dividend (or any other distribution), reclassification,
reorganization, consolidation, merger, sale, transfer, dissolution, liquidation
or winding up.

     

    SECTION
4.11.                                           Stockholder Rights
Plan

     

    .  Each
share of Common Stock issued upon conversion of Notes pursuant to this Article 4
shall be entitled to receive the appropriate number of rights, if any, and the
certificates representing the Common Stock issued upon such conversion shall
bear such legends, if any, in each case as may be provided by the terms of any
stockholder rights plan adopted by the Company, as the same may be amended from
time to time.  Notwithstanding the foregoing, if prior to any
conversion such rights have separated from

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    the
shares of Common Stock in accordance with the provisions of the applicable
stockholder rights agreement, the Conversion Rate shall be adjusted at the time
of separation as if the Company had distributed to all holders of the Common
Stock, shares of the Company’s capital stock, evidences of indebtedness, assets,
property, rights or warrants as described in Section 4.04(c) above, subject to
readjustment in the event of the expiration, termination or redemption of such
rights.

    SECTION
5.01.                                           Events of
Default

     

    .  In
addition to the Events of Default specified in Section 6.01 of the Original
Indenture, each of the following events shall be an “Event of Default” wherever
used herein with respect to the Notes:

     

    (a)           the

rescinded, within five days;

     

    (c)           failure

defined in the Credit Agreement) for money borrowed, whether such indebtedness
now exists or shall hereafter be created, shall happen and shall result in such
indebtedness in principal amount in excess of $50 million becoming or being
declared due and payable prior to the date on which it would otherwise become
due and payable, and such acceleration shall not be rescinded or annulled, or
such indebtedness shall not have been discharged, within a period of 30 days
after there shall have been given, by registered or certified mail, to the

specifying

     

    (g)           such
event of default and requiring the Company to cause such acceleration to be

    (h)           any

    (A)           commences

    SECTION
5.02.                                           Additional
Interest

     

    .  Notwithstanding
any provisions of the Indenture to the contrary, if the Company so elects, the
sole remedy for an Event of Default relating to any obligation to file documents
and reports with the Trustee as required by Section 314(a)(1) of the Trust
Indenture Act, Section 2.04 of this Supplemental Indenture, or Section 4.03(a)
of the Original Indenture shall for the first 180 days following the occurrence
of such Event of Default consist exclusively of the right to receive additional
interest on the Notes equal to 0.50% per annum of the principal amount of the
Notes (“Additional
Interest”).  In order to elect to pay Additional Interest as
the sole remedy during the first 180 days after the occurrence of an Event of
Default described in the preceding sentence, the Company must give notice to
Holders of the Notes, the Trustee and the Paying Agent of such election on or
before the close of business on the Business Day before the date on which such
Event of Default occurs.  If the Company so elects, such Additional
Interest shall be payable on all Notes outstanding on or before the date on
which such Event of Default first occurs until such Event of Default is cured or
waived or ceases to exist and will be payable in the same manner and on the same
dates as the stated interest payable on the Notes.  Upon the failure
to timely give all Holders, the Trustee and the Paying Agent such notice, the
Notes will be subject to immediate acceleration as provided in Section 6.02 of
the Original Indenture.  On the 180th day after such Event of Default
occurs (if such Event of Default is not cured or waived prior to such 180th
day), the Notes shall be subject to acceleration as provided in Section 6.02 of
the Original Indenture.  This Section 5.02 shall not

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    affect
the rights of Holders of Notes in the event of the occurrence of any other Event
of Default.  Whenever in the Indenture there is mentioned, in any
context, the payment of interest on, or in respect of, any Note, such mention
shall be deemed to include mention of the payment of Additional Interest
provided for in this Section 5.02 to the extent that, in such context,
Additional Interest is, was or would be payable in respect thereof pursuant to
the provisions of this Section 5.02, and express mention of the payment of
Additional Interest (if applicable) in any provision shall not be construed as
excluding Additional Interest in those provisions where such express mention is
not made.

     

    SECTION
5.03.                                           Company Compliance Certificates and
Notice of Defaults

     

    .  In addition to
any obligations of the Company under Section 4.03(a) of the Original Indenture,
the Company shall deliver to the Trustee, (i) within 120 days after the end of
each fiscal year, an Officers’ Certificate indicating whether or not the signers
thereof have knowledge of the occurrence of any Event of Default under the
Indenture during such fiscal year, and (ii) within 30 days after the occurrence
thereof, written notice of any events that would constitute an Event of Default
under the Indenture, the status of such events and the action that the Company
is taking or proposes to take in respect thereof.

     

    If a
Default or Event of Default with respect to the Notes occurs and is continuing
and it is known to the Trustee, the Trustee shall mail to Holders of Notes a
notice of the Default or Event of Default within 90 days after it
occurs.  Except in the case of a Default or Event of Default in
payment of principal of and interest on the Notes or a Default or Event of
Default in the payment or delivery of consideration due upon conversion of the
Notes, the Trustee may withhold the notice if and so long as a committee of its
Responsible Officers in good faith determines that withholding the notice is in
the interests of Holders of Securities of such series.

     

    SECTION
5.04.                                           Acceleration

     

    .  All references
in Section 6.02 of the Original Indenture to “clause (5) or (6) of Section 6.01”
of the Original Indenture shall be deemed to include references to Sections
5.01(g) and (h) of this Supplemental Indenture.

     

    SECTION
5.05.                                           Waiver of
Defaults.  The provisions on waiver of defaults set forth in
this Section 5.05 shall, with respect to the Notes, supersede in its entirety
Section 6.04 of the Original Indenture, and all references in the Original
Indenture to Section 6.04 thereof and waiver of defaults provisions therein, as
the case may be, shall, with respect to the Notes, be deemed to be references to
this Section 5.05 and the waiver of defaults provisions set forth in this
Section 5.05, respectively.

     

    Subject
to Section 5.06 of this Supplemental Indenture and Section 9.02 of the Original
Indenture, the Holders of a majority in principal amount of the then outstanding
Notes by notice to the Trustee may waive an existing or past Default or Event of
Default with respect to such Notes and its consequences, except (1) a continuing
Default or Event of Default in the payment of the principal or interest, if any,
with respect to any Note, (2) a continuing Default or Event of Default in the
payment or delivery of any consideration due upon conversion of any Note, or (3)
a continued Default in respect of a provision that under Section 9.02 of the
Original Indenture cannot be amended or supplemented without the consent of each
Holder affected.  Upon any such waiver, such Default shall cease to
exist, and any Event of Default arising therefrom shall

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    be deemed
to have been cured for every purpose of this Indenture, but no such waiver shall
extend to any subsequent or other Default or impair any right consequent
thereon.

     

    SECTION
5.06.                                           Rights of Holders to Receive
Payment.  The provisions on rights of holders to receive
payment set forth in this Section 5.06 shall, with respect to the Notes,
supersede in its entirety Section 6.07 of the Original Indenture, and all
references in the Original Indenture to Section 6.07 thereof and rights of
holders to receive payment provisions therein, as the case may be, shall, with
respect to the Notes, be deemed to be references to this Section 5.06 and the
rights of holders to receive payment provisions set forth in this Section 5.06,
respectively.

     

    Notwithstanding
any other provision of this Indenture, the right of any Holder of Notes to (i)
receive payment of principal and interest when due, (ii) receive payment or
delivery of the consideration due upon conversion, (iii) receive the Fundamental
Change Purchase Price when due, or (iv) bring suit for the enforcement of any of
(i), (ii) and (iii) above, is absolute and unconditional and shall not be
impaired or affected without the consent of such Holder.

    The
Company shall not consolidate with, merge with or into, any other Person or
convey, transfer or lease all or substantially all of the property and assets of
the Company and its Subsidiaries on a consolidated basis, to any Person or

Person formed by such consolidation or into which the Company is merged or the
Person that acquires by conveyance or transfer, or that leases, all or
substantially all the properties and assets of the Company and its Subsidiaries
on a consolidated basis shall be a corporation, limited liability company,

Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger, conveyance, transfer or lease and such supplemental
indenture comply with this Article and that all conditions precedent provided
for in the Indenture relating to such transaction have been complied
with.

semi-annually in arrears on each June 15 and December 15, commencing on December
15, 2009, to the Person in whose name this Note (or one or more predecessor
securities) is registered at the close of business on the Regular Record Date
for such interest.  Additional Interest will be payable at the option
of the Company on the terms set forth in Section 5.02 of the within-mentioned
Supplemental Indenture.

     

    The
Company will pay interest on overdue principal, and, to the extent lawful, on
overdue interest, in each case at a rate of 4.25% per annum.  Interest
not paid when due and any interest on principal or interest not paid when due
will be paid to Holders on a special record date, which will be the 15th day
preceding the date fixed by the Company for the payment of such interest,
whether or not such day is a Business Day.  At least 15 days before a
special record date, the Company will send to each Holder and to the Trustee a
notice that sets forth the special record date, the payment date and the amount
of interest to be paid.

     

    The
Company shall pay principal of and interest on this Note, so long as such Note
is a Global Note, in immediately available funds to the Depositary or its
nominee, as the case may be, as the registered Holder of such
Note.  The Company shall pay principal of any Notes (other than Notes
that are Global Notes) at the office or agency designated by the Company for
that purpose.  The Company has initially designated the Trustee as its
Paying Agent and Registrar in respect of the Notes and its agency in New York,
New York as a place where Notes may be presented for payment or for registration
of transfer.  The Company may, however, change the Paying Agent or
Registrar for the Notes without prior notice to the Holders thereof, and the
Company may act as Paying Agent or Registrar.  Interest on the Notes
(other than Notes that are Global Notes) will be payable (i) to Holders of the
Notes having an aggregate principal amount of Notes of $5,000,000 or less, by
check mailed to the Holders of these Notes at their address in the Security
Register and (ii) to Holders having an aggregate principal amount of Notes in
excess of $5,000,000, either by check mailed to each Holder at its address in
the Security Register or,

    upon
application by a Holder to the Registrar not later than the relevant Regular
Record Date, by wire transfer in immediately available funds to that Holder’s
account within the United States, which application shall remain in effect until
that Holder notifies, in writing, the Registrar to the contrary.

     

    Reference
is hereby made to the further provisions of this Note set forth on the reverse
hereof, which further provisions shall for all purposes have the same effect as
if set forth at this place.

case of any conflict between this Note and the Indenture, the provisions of the
Indenture shall control.  This Note, for all purposes, shall be
governed by and construed in accordance with the laws of the State of New
York.

referred to on the reverse hereof by manual signature, this Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any
purpose.

    This Note
is one of a duly authorized issue of Securities of the Company (herein called
the “Notes”), issued
under an Indenture dated as of June 10, 2009, as previously amended and
supplemented from time to time in accordance with the terms thereof (herein
called the “Original
Indenture”) and as further supplemented by the Supplemental Indenture
dated as of June10, 2009 (herein called the “Supplemental Indenture” and
the Original Indenture, as supplemented by the Supplemental Indenture, the
“Indenture”) by and
between the Company and Wells Fargo Bank, National Association, herein called
the “Trustee”, and
reference is hereby made to the Indenture for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Notes and of the terms upon which the Notes
are, and are to be, authenticated and delivered.  Additional Notes may
be issued in an unlimited aggregate principal amount, subject to certain
conditions specified in the Indenture.

     

    This Note
is not subject to redemption at the option of the Company prior to June 15, 2014
and, for the avoidance of doubt, this Note is not subject to the provisions of
Article III of the Original Indenture.  Nor is this Note subject to
Section 8.01(a)(1)(B)(ii) or (iii), 8.01(b) or 8.01(c) of the Original
Indenture.

     

    The
provisions in Article 6 of the Supplemental Indenture supersede the entirety of
Section 5.01 of the Original Indenture.

     

    As
provided in and subject to the provisions of the Indenture, upon the occurrence
of a Fundamental Change, the Holder has the right, at such Holder’s option, to
require the Company to repurchase all of such Holder’s Notes or any portion
thereof (in principal amounts of $1,000 or integral multiples thereof) on the
Fundamental Change Purchase Date at a price equal to the Fundamental Change
Purchase Price.

     

    As
provided in and subject to the provisions of the Indenture, the Holder hereof
has the right, at its option, during certain periods and upon the occurrence of
certain conditions specified in the Indenture, prior to the close of business on
the second Scheduled Trading Day immediately preceding June 15, 2014, to convert
this Note or a portion thereof that is $1,000 or an integral multiple thereof,
into cash, shares of Common Stock or a combination thereof, at the Company’s
discretion, at the applicable Conversion Rate specified in the Indenture, as
adjusted from time to time as provided in the Indenture.

     

    As
provided in and subject to the provisions of the Indenture, the Company will
make all payments and deliveries in respect of the Fundamental Change Purchase
Price and the principal amount of the Notes on the Stated Maturity thereof, as
the case may be, to the holder who surrenders a Note to the Paying Agent to
collect such payments in respect of the Note.  The Company will pay
cash amounts in money of the United States that at the time of payment is legal
tender for payment of public and private debts.

     

    
      
        
          A-

        

         

      

      
         

        
          

        

      

      
         

      

    

    The
Indenture permits, with certain exceptions as therein provided, the amendment
thereof and the modification of the rights and obligations of the Company and
the rights of the Holders of the Notes to be effected under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of a
majority in principal amount of the Notes at the time
outstanding.  The Indenture also contains provisions permitting the
Holders of specified percentages in principal amount of the Notes at the time
outstanding, on behalf of the Holders of all Notes, to waive compliance by the
Company with certain provisions of the Indenture and certain past defaults under
the Indenture and their consequences.  Any such consent or waiver by
the Holder of this Note shall be conclusive and binding upon such Holder and
upon all future Holders of this Note and of any Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this
Note.

     

    As
provided in and subject to the provisions of the Indenture, in case an Event of
Default, as defined in the Indenture, shall have occurred and be continuing, the
principal of and interest on all Notes may be declared due and payable, by
either the Trustee or Holders 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 provided
in the Indenture; provided that upon the
occurrence of an Event of Default specified in clauses (5) or (6) of Section
6.01 of the Original Indenture or clauses (g) and (h) of Section 5.01 of the
Supplemental Indenture, the principal amount of, and interest on, all the Notes
shall automatically become due and payable.

     

    No
reference herein to the Indenture and no provision of this Note or of the
Indenture shall alter or impair the obligation of the Company, which is absolute
and unconditional, to pay the principal of and any premium and interest on this
Note at the time, place and rate, and in the coin and currency, herein
prescribed.

     

    As
provided in the Indenture and subject to certain limitations therein set forth,

the Company in any place where the principal of and interest on this Note are

form satisfactory to the Company and the Registrar duly executed by, the Holder
hereof or his attorney duly authorized in writing, and thereupon one or more new
Notes of this series and of like tenor, of authorized denominations and for the
same aggregate principal amount, will be issued to the designated transferee or
transferees.

     

    The Notes
are issuable only in registered form without coupons in denominations of $1,000
and any integral multiple thereof.  As provided in the Indenture and
subject to certain limitations therein set forth, the Notes are exchangeable for
a like aggregate principal amount of Notes and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the
same.

     

    No
service charge shall be made for any such registration of transfer or exchange,
but the Company may require payment of a sum sufficient to cover any tax or
other governmental charge payable in connection therewith.
