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

      1.4

            	
              Acts
      of Holders; Record Dates.

            


    

    


    Any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the
Company.  The Trustee shall promptly deliver to the Company copies of
all such instrument or instruments delivered to the Trustee.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the “Act” of the Holders signing
such instrument or instruments.  Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Indenture and (subject to Section 6.1) conclusive in favor of
the Trustee and the Company, if made in the manner provided in this
Section.

    


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

    


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

    


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

    


    The
Company may set any day as a record date for the purpose of determining the
Holders of Outstanding Securities of any series entitled to give, make or take
any request, demand, authorization, direction, vote, notice, consent, waiver or
other action provided or permitted by this Indenture to be given, made or taken
by Holders of Securities of such series, provided that the Company may not set a
record date for, and the provisions of this paragraph shall not apply with
respect to, the giving or making of any notice, declaration, request or
direction referred to in the next paragraph.  If any record date is
set pursuant to this paragraph, the Holders of Outstanding Securities of the
relevant series on such record date, and no other Holders, shall be entitled to
take the relevant action, whether or not such Holders remain Holders after such
record date; provided that no such action shall be effective hereunder unless
taken on or prior to the applicable Expiration Date by Holders of the requisite
principal amount of Outstanding Securities of such series on such record
date.  Nothing in this paragraph shall be construed to prevent the
Company from setting a new record date for any action for which a record date
has previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person be canceled
and of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities of the relevant series on the date such action is
taken.  Promptly after any record date is set pursuant to this
paragraph, the Company, at its own expense, shall cause notice of such record
date, the proposed action by Holders and the applicable Expiration Date to be
given to the Trustee in writing and to each Holder of Securities of the relevant
series in the manner set forth in Section 1.6.

    The
Trustee may set any day as a record date for the purpose of determining the
Holders of Outstanding Securities of any series entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration
referred to in Section 5.2, (iii) any request to institute proceedings referred
to in Section 5.7(2) or (iv) any direction referred to in Section 5.12, in each
case with respect to Securities of such series.  If any record date is
set pursuant to this paragraph, the Holders of Outstanding Securities of such
series on such record date, and no other Holders, shall be entitled to join in
such notice, declaration, request or direction, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date.  Nothing in this paragraph shall be
construed to prevent the Trustee from setting a new record date for any action
for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action
by any Person be canceled and of no effect), and nothing in this paragraph shall
be construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date
such action is taken.  Promptly after any record date is set pursuant
to this paragraph, the Trustee, at the Company’s expense, shall cause notice of
such record date, the proposed action by Holders and the applicable Expiration
Date to be given to the Company in writing and to each Holder of Securities of
the relevant series in the manner set forth in Section 1.6.

    


    With
respect to any record date set pursuant to this Section, the party hereto which
sets such record dates may designate any day as the “Expiration Date” and from
time to time may change the Expiration Date to any earlier or later day;
provided that no such change shall be effective unless notice of the proposed
new Expiration Date is given to the other party hereto in writing, and to each
Holder of Securities of the relevant series in the manner set forth in Section
1.6, on or prior to the existing Expiration Date.  If an Expiration
Date is not designated with respect to any record date set pursuant to this
Section, the party hereto which set such record date shall be deemed to have
initially designated the 180th day after such record date as the Expiration Date
with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph.  Notwithstanding the foregoing, no
Expiration Date shall be later than the 180th day after the applicable record
date.

    


    Without
limiting the foregoing, a Holder entitled hereunder to take any action hereunder
with regard to any particular Security may do so with regard to all or any part
of the principal amount of such Security or by one or more duly appointed agents
each of which may do so pursuant to such appointment with regard to all or any
part of such principal amount.

furnished to, or filed with,

    


    
      	
               
      

            	
              (1)

            	
              the
      Trustee by any Holder or by the Company shall be sufficient for every
      purpose hereunder if made, given, furnished or filed in writing (or by
      facsimile transmissions, provided that oral confirmation of receipt shall
      have been received) to or with the Trustee at its Corporate Trust Office,
      Attention: Corporate Trust Department,

              the
      Company by the Trustee or by any Holder shall be sufficient for every
      purpose hereunder (unless otherwise herein expressly provided) if in
      writing and mailed, first-class postage prepaid, personally delivered or
      sent via overnight courier to the Company addressed to it at the address
      of its principal office specified in the first paragraph of this
      instrument or at any other address previously furnished in writing to the
      Trustee by the Company, Attention: Chief Financial
  Officer.

              Notice
      to Holders; Waiver.

            


    

    


    Where
this Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, or delivered by hand or overnight
courier, to each Holder affected by such event, at its address as it appears in
the Security Register, not later than the latest date (if any), and not earlier
than the earliest date (if any), prescribed for the giving of such
notice.  Neither the failure to mail or deliver by hand or overnight
courier any notice, nor any defect in any notice so mailed or delivered by hand
or overnight courier, to any particular Holder shall affect the sufficiency of
such notice with respect to other Holders.  Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice.  Waivers of notice
by Holders shall be filed with the Trustee, but such filing shall not be a
condition precedent to the validity of any action taken in reliance upon such
waiver.

    


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

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

Security or the last date on which a Holder has the right to convert a Security
at a particular conversion price or conversion rate, as the case may be, shall

provision of this Indenture or of the Securities (other than a provision of any
Security which specifically states that such provision shall apply in lieu of
this Section)) payment of interest or principal (and premium, if any) or, if
applicable to a particular series of Securities, conversion need not be made at
such Place of Payment on such date, but may be made on the next succeeding
Business Day at such Place of Payment with the same force and effect as if made
on the Interest Payment Date or Redemption Date, at the Stated Maturity or on
such last day for conversion, as the case may be.

subsidiary, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law, or

Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
of this series not less than 10 days prior to such Special Record Date, or be
paid at any time in any other lawful manner not inconsistent with the

acceleration, upon redemption or at Stated Maturity and in such case the overdue
principal and any overdue premium shall bear interest at the rate of __________%
per annum (to the extent that the payment of such interest shall be legally
enforceable), from the dates such amounts are due until they are paid or made
available for payment.  Interest on any overdue principal or premium

or premium which is not paid on demand shall bear interest at the rate of

public and private debts [if applicable, insert —; provided, however, that at
the option of the Company payment of interest may be made by check mailed to the
address of the Person entitled thereto as such address shall appear in the
Security Register].

    All
Securities of any one series shall be substantially identical except as to
denomination and except as may otherwise be provided in or pursuant to the Board
Resolution referred to above and (subject to Section 3.3) set forth, or
determined in the manner provided, in the Officers’ Certificate referred to
above or in any such indenture supplemental hereto.

    


    If any of
the terms of the series are established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action shall be certified by
the Secretary or an Assistant Secretary of the Company and delivered to the
Trustee at or prior to the delivery of the Officers’ Certificate setting forth
the terms of the series.

    The
Securities of each series shall be issuable only in registered form without
coupons and only in such denominations as shall be specified as contemplated by
Section 3.1.  In the absence of any such specified denomination with
respect to the Securities of any series, the Securities of such series shall be
issuable in denominations of $1,000 and any integral multiple
thereof.

              Execution,

Dating.

            


    

    


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

    


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

    


    At any
time and from time to time after the execution and delivery of this Indenture,
the Company may deliver Securities of any series executed by the Company to the
Trustee for authentication, together with a Company Order for the authentication
and delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities.  If the form or
terms of the Securities of the series have been established by or pursuant to
one or more Board Resolutions as permitted by Sections 2.1 and 3.1, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 6.1) shall be fully protected in
relying upon, a copy of such Board Resolution, the Officers’ Certificate setting
forth the terms of the series and an Opinion of Counsel, with such Opinion of
Counsel stating,

    


    
      	
               
      

            	
              (1)

            	
              if
      the form of such Securities has been established by or pursuant to Board
      Resolution as permitted by Section 2.1, that such form has been
      established in conformity with the provisions of this
      Indenture;

            


    

    


    
      	
               
      

            	
              (2)

            	
              if
      the terms of such Securities have been established by or pursuant to Board
      Resolution as permitted by Section 3.1, that such terms have been
      established in conformity with the provisions of this Indenture;
      and

            


    

    


    
      	
               
      

            	
              (3)

            	
              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 legally
      binding obligations of the Company enforceable in accordance with their
      terms, subject to bankruptcy, insolvency, fraudulent transfer,
      reorganization, moratorium and similar laws of general applicability
      relating to or affecting creditors’ rights and to general equity
      principles.

            


    

    


    If such
form or terms have been so established, the Trustee shall not be required to
authenticate such Securities if the issue of such Securities pursuant to this
Indenture will affect the Trustee’s own rights, duties or immunities under the
Securities and this Indenture or otherwise in a manner which is not reasonably
acceptable to the Trustee.

    


    Notwithstanding
the provisions of Section 3.1 and of the preceding paragraph, if all Securities
of a series are not to be originally issued at one time, it shall not be
necessary to deliver the Officers’ Certificate otherwise required pursuant to
Section 3.1 or the Company Order and Opinion of Counsel otherwise required
pursuant to such preceding paragraph at or prior to the authentication of each
Security of such series if such documents are delivered at or prior to the
authentication upon original issuance of the first Security of such series to be
issued.

    Each
Security shall be dated the date of its authentication.

    


    No
Security shall be entitled to any benefit under this Indenture or be valid or
obligatory for any purpose unless there appears on such Security a certificate
of authentication substantially in the form provided for herein executed by the
Trustee by manual signature, and such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder.  Notwithstanding the foregoing,
if any Security shall have been authenticated and delivered hereunder but never
issued and sold by the Company, and the Company shall deliver such Security to
the Trustee for cancellation as provided in Section 3.9, 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.

    


    Neither
the Company nor the Trustee shall have any responsibility for any defect in the
CUSIP number that appears on any Security, check, advice of payment or
redemption notice, and any such document may contain a statement to the effect
that CUSIP numbers have been assigned by an independent service for convenience
of reference and that neither the Company nor the Trustee shall be liable for
any inaccuracy in such numbers.

              Temporary
      Securities.

            


    

    


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

    


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

              Registration;
      Registration of Transfer and
Exchange.

            


    

    


    The
Company shall cause to be kept at the Corporate Trust Office of the Trustee a
register (the register maintained in such office and in any other office or
agency of the Company in a Place of Payment being herein sometimes collectively
referred to as the “Security Register”) in which, subject to such reasonable
regulations as it may prescribe, the Company shall provide for the registration
of Securities and of transfers of Securities.  The Trustee is hereby
appointed “Security Registrar” for the purpose of registering Securities and
transfers of Securities as herein provided.

    Upon
surrender for registration of transfer of any Security of a series at the office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Securities of the same
series, of any authorized denominations and of like tenor and aggregate
principal amount.

    


    At the
option of the Holder, Securities of any series may be exchanged for other
Securities of the same series, of any authorized denominations and of like tenor
and aggregate principal amount, upon surrender of the Securities to be exchanged
at such office or agency.  Whenever any Securities are so surrendered
for exchange, the Company shall execute, and the Trustee shall authenticate and
deliver, the Securities that the Holder making the exchange is entitled to
receive.

    


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

    


    Every
Security presented or surrendered for registration of transfer or for exchange
shall (if so required by the Company or the Trustee) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed, by the Holder thereof or its
attorney duly authorized in writing.

    


    No
service charge shall be made for any registration of transfer or exchange of
Securities, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Securities, other than exchanges
pursuant to Section 3.4, 9.6 or 11.7 not involving any transfer.

    


    If the
Securities of any series (or of any series and specified tenor) are to be
redeemed in part, the Company shall not be required (A) to issue, register the
transfer of or exchange any Securities of that series (or of that series and
specified tenor, as the case may be) during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of any
such Securities selected for redemption under Section 11.3 and ending at the
close of business on the day of such mailing, or (B) to register the transfer of
or exchange any Security so selected for redemption in whole or in part, except
the unredeemed portion of any Security being redeemed in part.

    


    The
provisions of clauses (1), (2), (3) and (4) below shall apply only to Global
Securities:

    


    
      	
               
      

            	
              (1)

            	
              Each
      Global Security authenticated under this Indenture shall be registered in
      the name of the Depositary designated for such Global Security or a
      nominee thereof and delivered to such Depositary or a nominee thereof or
      custodian therefor, and each such Global Security shall constitute a
      single Security for all purposes of this
  Indenture.

            


    

    


    
      	
               
      

            	
              (2)

            	
              Notwithstanding
      any other provision in this Indenture, no Global Security may be exchanged
      in whole or in part for Securities registered, and no transfer of a Global
      Security in whole or in part may be registered, in the name of any Person
      other than the Depositary for such Global Security or a nominee thereof
      unless (A) such Depositary (i) has notified the Company that it is
      unwilling or unable to continue as Depositary for such Global Security or
      (ii) has ceased to be a clearing agency registered under the Exchange Act,
      (B) there shall have occurred and be continuing an Event of Default with
      respect to such Global Security or (C) there shall exist such
      circumstances, if any, in addition to or in lieu of the foregoing as have
      been specified for this purpose as contemplated by Section
      3.1.

              Subject
      to clause (2) above, any exchange of a Global Security for other
      Securities may be made in whole or in part, and all Securities issued in
      exchange for a Global Security or any portion thereof shall be registered
      in such names as the Depositary for such Global Security shall
      direct.

      Security authenticated and delivered upon registration of transfer of, or
      in exchange for or in lieu of, a Global Security or any portion thereof,
      whether pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.7 or
      otherwise, shall be authenticated and delivered in the form of, and shall
      be, a Global Security, unless such Security is registered in the name of a
      Person other than the Depositary for such Global Security or a nominee
      thereof.

            


    

    


    
      	
              Section
      3.6

            	
              Mutilated,
      Destroyed, Lost and Stolen
Securities.

            


    

    


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

    


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

    


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

    


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

    


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

    


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

    Except as
otherwise provided as contemplated by Section 3.1 with respect to any series of
Securities or in a supplemental indenture with respect to any series of
Securities, interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the Person in
whose name that Security (or one or more Predecessor Securities) is registered
at the close of business on the Regular Record Date for such
interest.

    


    Any
interest on any Security of any series which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date (herein called
“Defaulted Interest”) shall forthwith cease to be payable to the Holder on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

    


    
      	
               
      

            	
              (1)

            	
              The
      Company may elect to make payment of any Defaulted Interest to the Persons
      in whose names the Securities of such series (or their respective
      Predecessor Securities) are registered at the close of business on a
      Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner.  The Company shall
      notify the Trustee in writing of the amount of Defaulted Interest proposed
      to be paid on each Security of such series and the date of the proposed
      payment, and at the same time the Company shall deposit with the Trustee
      an amount of money equal to the aggregate amount proposed to be paid in
      respect of such Defaulted Interest or shall make arrangements satisfactory
      to the Trustee for such deposit prior to the date of the proposed payment,
      such money when deposited to be held in trust for the benefit of the
      Persons entitled to such Defaulted Interest as in this clause
      provided.  Thereupon the Trustee shall fix a Special Record Date
      for the payment of such Defaulted Interest, which shall be not more than
      15 days and not less than 10 days prior to the date of the proposed
      payment and not less than 10 days after the receipt by the Trustee of the
      notice of the proposed payment.  The Trustee shall promptly
      notify the Company of such Special Record Date and, in the name and at the
      expense of the Company, shall cause notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor to be given to
      each Holder of Securities of such series in the manner set forth in
      Section 1.6, not less than 10 days prior to such Special Record
      Date.  Notice of the proposed payment of such Defaulted Interest
      and the Special Record Date therefor having been so mailed, such Defaulted
      Interest shall be paid to the Persons in whose names the Securities of
      such series (or their respective Predecessor Securities) are registered at
      the close of business on such Special Record Date and shall no longer be
      payable pursuant to the following clause
(2).

            


    

    


    
      	
               
      

            	
              (2)

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

            


    

    


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

    Prior to
due presentment of a Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the Person in
whose name such Security is registered as the owner of such Security for the
purpose of receiving payment of principal of and any premium and (subject to
Section 3.7) any interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

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

              any

      in the Board Resolution, supplemental indenture or Officers’ Certificate

              Acceleration
      of Maturity; Rescission and
Annulment.

            


    

    


    Unless
the Board Resolution, supplemental indenture or Officers’ Certificate
establishing such series provides otherwise, if an Event of Default (other than
an Event of Default specified in Section 5.1(5) or 5.1(6)) with respect to
Securities of any series at the time Outstanding occurs and is continuing, then
in every such case the Trustee or the Holders of not less than 25% in principal
amount of the Outstanding Securities of that series may declare the principal
amount of all the Securities of that series (or, if any Securities of that
series are Original Issue Discount Securities, such portion of the principal
amount of such Securities as may be specified by the terms thereof), and
premium, if any, together with accrued and unpaid interest, if any, thereon, to
be due and payable immediately, by a notice in writing to the Company (and to
the Trustee if given by the Holders), and upon any such declaration such
principal amount (or specified amount), and premium, if any, together with
accrued and unpaid interest, if any, thereon, shall become immediately due and
payable.  If an Event of Default specified in Section 5.1(5) or 5.1(6)
with respect to Securities of any series at the time Outstanding occurs, the
principal amount of all the Securities of that series (or, if any Securities of
that series are Original Issue Discount Securities, such portion of the
principal amount of such Securities as may be specified by the terms thereof),
and premium, if any, together with accrued and unpaid interest, if any, thereon,
shall automatically, and without any declaration or other action on the part of
the Trustee or any Holder, become immediately due and payable.  Any
payments by the Company on the Securities following any such acceleration will
be subject to the subordination provisions of Article 15 to the extent provided
therein.

    


    At any
time after such a declaration of acceleration with respect to Securities of any
series has been made and before a judgment or decree for payment of the money
due has been obtained by the Trustee as hereinafter in this Article provided,
the Holders of a majority in principal amount of the Outstanding Securities of
that series, by written notice to the Company and the Trustee, may rescind and
annul such declaration and its consequences if

              the

              the
      principal of (and premium, if any, on) any Securities of that series which
      have become due otherwise than by such declaration of acceleration and any
      interest thereon at the rate or rates prescribed therefor in such
      Securities,

      the extent that payment of such interest is lawful, interest upon overdue
      interest at the rate or rates prescribed therefor in such Securities,
      and

      sums paid or advanced by the Trustee hereunder and the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its
      agents and counsel; and

              all
      Events of Default with respect to Securities of that series, other than
      the non-payment of the principal of Securities of that series that have
      become due solely by such declaration of acceleration, have been cured or
      waived as provided in Section 5.13.

            


    

    


    No such
rescission shall affect any subsequent default or impair any right consequent
thereon.

              (1)

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

            


    

    


    
      	
               
      

            	
              (2)

            	
              default
      is made in the payment of the principal of (or premium, if any, on) any
      Security at the Maturity thereof,

            


    

    


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

    


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

              Trustee
      May File Proofs of Claim.

            


    

    


    In case
of any judicial proceeding relative to the Company (or any other obligor upon
the Securities), its property or its creditors, the Trustee shall be entitled
and empowered, by intervention in such proceeding or otherwise, to take any and
all actions authorized under the Trust Indenture Act in order to have claims of
the Holders and the Trustee allowed in any such proceeding.  In
particular, the Trustee shall be authorized to collect and receive any moneys or
other property payable or deliverable on any such claims and to distribute the
same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator
or other similar official in any such judicial proceeding is hereby authorized
by each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.7.  No provision of this
Indenture shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder
thereof or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding; provided, however, that the Trustee may, on
behalf of the Holders, vote for the election of a trustee in bankruptcy or
similar official and be a member of a creditors’ or other similar
committee.

    All
rights of action and claims under this Indenture or the Securities may be
prosecuted and enforced by the Trustee without the possession of any of the
Securities or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after provision
for the payment of the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel, be for the ratable benefit of
the Holders of the Securities in respect of which such judgment has been
recovered.

following order, at the date or dates fixed by the Trustee and, in case of the
distribution of such money on account of principal or any premium or interest,

              the
      Holders of at least a majority in aggregate principal amount of the
      Outstanding Securities of that series shall have made written request to

      in its own name as Trustee
hereunder;

in any manner whatever by virtue of, or by availing of, any provision of this
Indenture to affect, disturb or prejudice the rights of any other of such
Holders, or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the

right, which is absolute and unconditional, to receive payment of the principal
of and any premium and (subject to Section 3.7) interest on such Security on the
respective Stated Maturities expressed in such Security (or, in the case of
redemption, on the Redemption Date), to convert such Securities in accordance
with Article 14 to the extent that such right to convert is applicable to such
Security, and to institute suit for the enforcement of any such payment, and
such rights shall not be impaired without the consent of such
Holder.

      of Rights and Remedies.

            


    

    


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

right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or
remedy.

    No delay

right or remedy accruing upon any Event of Default shall impair any such right
or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein.  Every right and remedy given by this Article or by law to
the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee (subject to the limitations contained
in this Indenture) or by the Holders, as the case may be.

Holders of not less than a majority in principal amount of the Outstanding
Securities of any series may on behalf of the Holders of all the Securities of
such series waive any past default hereunder with respect to such series and its
consequences, except

      respect of a covenant or provision hereof which under Article 9 cannot be
      modified or amended without the consent of the Holder of each Outstanding
      Security of such series 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.

    In any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken, suffered or omitted by it as
Trustee, a court may require any party litigant in such suit to file an
undertaking to pay the costs of such suit, and may assess costs against any such
party litigant, in the manner and to the extent provided in the Trust Indenture
Act; provided that neither this Section nor the Trust Indenture Act shall be
deemed to authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company or in any suit for the
enforcement of the right to convert any Security in accordance with Article
14.

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

    THE
TRUSTEE

    


    
      	
              Section
      6.1

            	
              Certain
      Duties and Responsibilities.

            


    

    


    The
duties and responsibilities of the Trustee shall be as provided by the Trust
Indenture Act.  Notwithstanding the foregoing, no provision of this
Indenture shall require the Trustee to expend or risk its own funds or otherwise
incur any financial liability in the performance of any of its duties hereunder,
or in the exercise of any of its rights or powers if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity against
such risk or liability is not reasonably assured to it.  Whether or
not therein expressly so provided, every provision of this Indenture relating to
the conduct or affecting the liability of or affording protection to the Trustee
shall be subject to the provisions of this Section.

    


    
      	
              Section
      6.2

            	
              Notice
      of Defaults.

            


    

    


    If a
default occurs hereunder with respect to Securities of any series, the Trustee
shall give the Holders of Securities of such series notice of such default as
and to the extent provided by the Trust Indenture Act; provided, however, that
except in the case of a default in the payment of principal of (or premium, if
any) or interest on any Securities of such series or in the payment of any
sinking fund installment or any conversion right applicable to Securities of
such series, the Trustee shall be protected in withholding such notice if and so
long as a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determine that the withholding of such notice is in the
interests of the holders of Securities of such series; provided, further,
however, that in the case of any default of the character specified in Section
5.1(4) with respect to Securities of such series, no such notice to Holders
shall be given until at least 60 days after the occurrence
thereof.  For the purpose of this Section, the term “default” means
any event that is, or after notice or lapse of time or both would become, an
Event of Default with respect to Securities of such series.

    


    Except
with respect to Section 10.1, the Trustee shall have no duty to inquire as to
the performance of the Company with respect to the covenants contained in
Article 10.  In addition, the Trustee shall not be deemed to have
knowledge of an Event of Default except (i) any Default or Event of Default
occurring pursuant to Sections 5.1(1), 5.1(2) and 5.1(3) (defaults in payments
on the Securities) or (ii) any Default or Event of Default of which the Trustee
shall have received written notification or obtained actual
knowledge.

    


    Delivery
of reports, information and documents to the Trustee under Section 7.4 is for
informational purposes only and the Trustee’s receipt of the foregoing shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company’s
compliance with any of their covenants hereunder (as to which the Trustee is
entitled to rely conclusively on Officers’ Certificates).

              Section
      6.3

            	
              Certain
      Rights of Trustee.

            


    

    


    Subject
to the provisions of Section 6.1:

    


    
      	
               
      

            	
              (1)

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

            


    

    


    
      	
               
      

            	
              (2)

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

            


    

    


    
      	
               
      

            	
              (3)

            	
              whenever
      in the administration of this Indenture the Trustee shall deem it
      desirable that a matter be proved or established prior to taking,
      suffering or omitting any action hereunder, the Trustee (unless other
      evidence be herein specifically prescribed) is entitled to and may, in the
      absence of bad faith on its part, rely upon an Officers’
      Certificate;

            


    

    


    
      	
               
      

            	
              (4)

            	
              the
      Trustee may consult with counsel 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;

            


    

    


    
      	
               
      

            	
              (5)

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

            


    

    


    
      	
               
      

            	
              (6)

            	
              the
      Trustee shall not be bound to make any investigation into the facts or
      matters stated in any resolution, certificate, statement, instrument,
      opinion, report, notice, request, direction, consent, order, bond,
      debenture, note, other evidence of indebtedness or other paper or
      document, but the Trustee, in its discretion, may make such further
      inquiry or investigation into such facts or matters as it may see fit,
      and, if the Trustee shall determine to make such further inquiry or
      investigation, it shall be entitled to examine the books, records and
      premises of the Company, personally or by agent or attorney;
      and

            


    

    


    
      	
               
      

            	
              (7)

            	
              the
      Trustee may execute any of the trusts or powers hereunder or perform any
      duties hereunder either directly or by or through agents or attorneys and
      the Trustee shall not be responsible for any misconduct or negligence on
      the part of any agent or attorney appointed with due care by it
      hereunder.

            


    

    


    
      	
              Section
      6.4

            	
              Not
      Responsible for Recitals or Issuance of
  Securities.

            


    

    


    The
recitals contained herein and in the Securities, except the Trustee’s
certificates of authentication, shall be taken as the statements of the Company,
and neither the Trustee nor any Authenticating Agent assumes any responsibility
for their correctness.  The Trustee makes no representations as to the
validity, sufficiency or priority of this Indenture or of the
Securities.  Neither the Trustee nor any Authenticating Agent shall be
accountable for the use or application by the Company of Securities or the
proceeds thereof.


    
      
         


      

      
        -38-

        
          

        

      

      
         


      

    


    
      	
              Section
      6.5

            	
              May
      Hold Securities and Act as Trustee under Other
  Indentures.

            


    

    


    The
Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or
any other agent of the Company, in its individual or any other capacity, may
become the owner or pledgee of Securities and, subject to Sections 6.8 and 6.13,
may otherwise deal with the Company with the same rights it would have if it
were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such
other agent.

    


    Subject
to the limitations imposed by the Trust Indenture Act, nothing in this Indenture
shall prohibit the Trustee from becoming and acting as trustee under other
indentures under which other securities, or certificates of interest of
participation in other securities, of the Company are outstanding in the same
manner as if it were not Trustee hereunder.

    


    
      	
              Section
      6.6

            	
              Money
      Held in Trust.

            


    

    


    Money
held by the Trustee in trust hereunder need not be segregated from other funds
except to the extent required by law.  The Trustee shall be under no
liability for interest on any money received by it hereunder except as otherwise
agreed with the Company.

    


    
      	
              Section
      6.7

            	
              Compensation
      and Reimbursement.

            


    

    


    The
Company agrees:

    


    
      	
               
      

            	
              (1)

            	
              to
      pay to the Trustee from time to time reasonable compensation for all
      services rendered by it hereunder (which compensation shall not be limited
      by any provision of law in regard to the compensation of a trustee of an
      express trust);

            


    

    


    
      	
               
      

            	
              (2)

            	
              except
      as otherwise expressly provided herein, to reimburse the Trustee upon its
      request for all reasonable expenses, disbursements and advances incurred
      or made by the Trustee in accordance with any provision of this Indenture
      (including the reasonable compensation and the expenses and disbursements
      of its agents and counsel), except any such expense, disbursement or
      advance as may be attributable to its negligence or bad faith;
      and

            


    

    


    
      	
               
      

            	
              (3)

            	
              to
      indemnify the Trustee for, and to hold it harmless against, any loss,
      liability or expense incurred without negligence or bad faith on its part,
      arising out of or in connection with the acceptance or administration of
      the trust or trusts hereunder, including the costs and expenses of
      defending itself against any claim or liability in connection with the
      exercise or performance of any of its powers or duties
      hereunder.

            


    

    


    When the
Trustee incurs expenses or renders services after an Event of Default specified
in Section 5.1(5) or Section 5.1(6) hereof occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
applicable bankruptcy, insolvency, reorganization or similar
law.


    
      
         


      

      
        -39-

      6.8

            	
              Conflicting
      Interests.

            


    

    


    If the
Trustee has or shall acquire a conflicting interest within the meaning of the
Trust Indenture Act and there is an Event of Default under the Securities of
that series, the Trustee shall either eliminate such interest or resign, to the
extent and in the manner provided by, and subject to the provisions of, the
Trust Indenture Act and this Indenture.  To the extent permitted by
the Trust Indenture Act, the Trustee shall not be deemed to have a conflicting
interest by virtue of being a trustee under this Indenture with respect to
Securities of more than one series.

    


    
      	
              Section
      6.9

            	
              Corporate
      Trustee Required; Eligibility.

            


    

    


    There
shall at all times be one (and only one) Trustee hereunder with respect to the
Securities of each series, which may be Trustee hereunder for Securities of one
or more other series.  Each Trustee shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such and has (or if the Trustee is
a member of a bank holding company system, its bank holding company has) a
combined capital and surplus of at least $50,000,000.  If any such
Person or bank holding company publishes reports of condition at least annually,
pursuant to law or to the requirements of its supervising or examining
authority, then for the purposes of this Section and to the extent permitted by
the Trust Indenture Act, the combined capital and surplus of such Person or bank
holding company shall be deemed to be its combined capital and surplus as set
forth in its most recent report of condition so published.  If at any
time the Trustee with respect to the Securities of any series shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

    


    
      	
              Section
      6.10

            	
              Resignation
      and Removal; Appointment of
Successor.

            


    

    


    No
resignation or removal of the Trustee and no appointment of a successor Trustee
pursuant to this Article shall become effective until the acceptance of
appointment by the successor Trustee in accordance with the applicable
requirements of Section 6.11.  The Trustee may resign at any time with
respect to the Securities of one or more series by giving written notice thereof
to the Company.  If the instrument of acceptance by a successor
Trustee required by Section 6.11 shall not have been delivered to the Trustee
within 30 days after the giving of such notice of resignation, the resigning
Trustee may petition any court of competent jurisdiction for the appointment of
a successor Trustee with respect to the Securities of such series.

    


    The
Trustee may be removed at any time with respect to the Securities of any series
by Act of the Holders of a majority in principal amount of the Outstanding
Securities of such series, delivered to the Trustee and to the
Company.

    


    If at any
time:

    


    
      	
               
      

            	
              (1)

            	
              the
      Trustee shall fail to comply with Section 6.8 after written request
      therefor by the Company or by any Holder who has been a bona fide Holder
      of a Security for at least six months,
or

            


    

    


    
      	
               
      

            	
              (2)

            	
              the
      Trustee shall cease to be eligible under Section 6.9 and shall fail to
      resign after written request therefor by the Company or by any such
      Holder, or

            


    


    
      
         


      

      
        -40-

        
          

        

      

      
         


      

    


    
      	
               
      

            	
              (3)

            	
              the
      Trustee shall become incapable of acting or shall be adjudged a bankrupt
      or insolvent or a receiver of the Trustee or of its property shall be
      appointed or any public officer shall take charge or control of the
      Trustee or of its property or affairs for the purpose of rehabilitation,
      conservation or liquidation, then, in any such case, (A) the Company by a
      Board Resolution may remove the Trustee with respect to all Securities, or
      (B) subject to Section 5.14, any Holder who has been a bona fide Holder of
      a Security for at least six months may, on behalf of himself and all
      others similarly situated, petition any court of competent jurisdiction
      for the removal of the Trustee with respect to all Securities and the
      appointment of a successor Trustee or
Trustees.

            


    

    


    If the
Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, with respect to the
Securities of one or more series, the Company, by a Board Resolution, 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) and shall comply with the applicable
requirements of Section 6.11.  If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any series shall be
appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment in accordance with the applicable requirements of Section
6.11, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the
Company.  If no successor Trustee with respect to the Securities of
any series shall have been so appointed by the Company or the Holders and
accepted appointment in the manner required by Section 6.11, the retiring
Trustee may petition, or any Holder who has been a bona fide Holder of a
Security of such series for at least six months may petition, on behalf of
himself and all others similarly situated, any court of competent jurisdiction
for the appointment of a successor Trustee with respect to the Securities of
such series.

    


    The
Company shall give notice of each resignation and each removal of the Trustee
with respect to the Securities of any series and each appointment of a successor
Trustee with respect to the Securities of any series to all Holders of
Securities of such series in the manner provided in Section 1.6.  Each
notice shall include the name of the successor Trustee with respect to the
Securities of such series and the address of its Corporate Trust
Office.

    


    
      	
              Section
      6.11

            	
              Acceptance
      of Appointment by Successor.

            


    

    


    In case
of the appointment hereunder of a successor Trustee with respect to all
Securities, every such successor Trustee so appointed shall execute, acknowledge
and deliver to the Company and to the retiring Trustee an instrument accepting
such appointment, and thereupon the resignation or removal of the retiring
Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts
and duties of the retiring Trustee; but, on the request of the Company or the
successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the
rights, powers and trusts of the retiring Trustee and shall duly assign,

    In case
of the appointment hereunder 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
series shall execute and deliver an indenture supplemental hereto wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts 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 contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts 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, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that 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; and 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, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts 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; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

    


    Upon
request of any such successor Trustee, the Company shall execute any and all
instruments for more fully and certainly vesting in and confirming to such
successor Trustee all such rights, powers and trusts referred to in the first or
second preceding paragraph, as the case may be.

    


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

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

Company.

            


    

    


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

              Appointment
      of Authenticating Agent.

            


    

    


    The
Trustee may appoint an Authenticating Agent or Agents with respect to one or
more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued upon original issue and
upon exchange, registration of transfer or partial redemption thereof or
pursuant to Section 3.6, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder.  Wherever
reference is made in this Indenture to the authentication and delivery of
Securities by the Trustee or the Trustee’s certificate of authentication, such
reference shall be deemed to include authentication and delivery on behalf of
the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent.  Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, any State thereof or the District of Columbia, authorized
under such laws to act as Authenticating Agent, having (or if the Authenticating
Agent is a member of a bank holding company system, its bank holding company
has) a combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or State authority.  If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published.  If at
any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, such Authenticating Agent shall resign
immediately in the manner and with the effect specified in this
Section.

    


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

    


    An
Authenticating Agent may resign at any time by giving written notice thereof to
the Trustee and to the Company.  The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company.  Upon receiving such a notice
of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will
serve.  Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent.  No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

    The
Trustee agrees to pay to each Authenticating Agent from time to time reasonable
compensation for its services under this Section, and the Trustee shall be
entitled to be reimbursed for such payments, subject to the provisions of
Section 6.7.

    


    If an
appointment with respect to one or more series is made pursuant to this Section
6.12, the Securities of such series may have endorsed thereon, in lieu of the
Trustee’s certificate of authentication, an alternative certificate of
authentication in the following form:

    


    This is
one of the Securities of the series designated therein referred to in the
within-mentioned Indenture.

    In
executing, or accepting the additional trusts created by, any supplemental
indenture permitted by this Article or the modifications thereby of the trusts
created by this Indenture, the Trustee shall be entitled to receive, and
(subject to Sections 6.1 and 6.3) shall be fully protected in relying upon, an
Opinion of Counsel stating that the execution of such supplemental indenture is

    Upon the

supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture.  If the Company shall so
determine, new Securities of any series so modified as to conform, in the

              Payment
      of Principal, Premium and Interest.

            


    

    


    The
Company covenants and agrees for the benefit of each series of Securities that
it will duly and punctually pay the principal of and any premium and interest on
the Securities of that series in accordance with the terms of the Securities and
this Indenture.

    


    
      	
              Section
      10.2

            	
              Maintenance
      of Office or Agency.

            


    

    


    The
Company will maintain in each Place of Payment for any series of Securities an
office or agency where Securities of that series may be presented or surrendered
for payment, where Securities of that series may be surrendered for registration
of transfer or exchange, where Securities of that series may be surrendered for
conversion and where notices and demands to or upon the Company in respect of
the Securities of that series and this Indenture may be served.  The
Company will give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency.  If at any time the
Company shall fail to maintain any such required office or agency or shall fail
to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all
such presentations, surrenders, notices and demands.  Unless otherwise
provided in a supplemental indenture or pursuant to Section 3.1 hereof, the
Place of Payment for any series of Securities shall be 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.

    


    
      	
              Section
      10.3

            	
              Money
      for Securities Payments to be Held in
Trust.

            


    

    


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

    


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

    


    The
Company will cause each Paying Agent for any series of Securities other than the
Trustee to execute and deliver to the Trustee an instrument in which such Paying
Agent shall agree with the Trustee, subject to the provisions of this Section,
that such Paying Agent will (1) comply with the provisions of the Trust
Indenture Act applicable to it as a Paying Agent and (2) during the continuance
of any default by the Company (or any other obligor upon the Securities of that
series) in the making of any payment in respect of the Securities of that
series, upon the written request of the Trustee, forthwith pay to the Trustee
all sums held in trust by such Paying Agent for payment in respect of the
Securities of that series.

    


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

    


    Any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of or any premium or interest on any
Security of any series and remaining unclaimed for a period ending on the
earlier of the date that is ten Business Days prior to the date such money would
escheat to the State or two years after such principal, premium or interest has
become due and payable shall be paid to the Company on Company Request, or (if
then held by the Company) shall be discharged from such trust; and the Holder of
such Security shall thereafter, as an unsecured general creditor, look only to
the Company for payment thereof, and all liability of the Trustee or such Paying
Agent with respect to such trust money, and all liability of the Company as
trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in each Place of Payment, notice that such money remains unclaimed
and that, after a date specified therein, which shall not be less than 30 days
from the date of such publication, any unclaimed balance of such money then
remaining will be repaid to the Company.

    The
Company will deliver to the Trustee, within 120 days after the end of each
fiscal year of the Company ending after the date hereof, an Officers’
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions of this Indenture (without regard to any period of
grace or requirement of notice provided hereunder) and, if the Company shall be
in default, specifying all such defaults and the nature and status thereof of
which they may have knowledge.  The fiscal year of the Company
currently ends on December 31; and the Company will give the Trustee prompt
written notice of any change of its fiscal year.

    Except as
otherwise specified as contemplated by Section 3.1 for Securities of such
series, the Company may, with respect to the Securities of any series, omit in
any particular instance to comply with any term, provision or condition set
forth in any covenant provided pursuant to Section 3.1(19), 9.1(2) or 9.1(7) for
the benefit of the Holders of such series if before the time for such compliance
the Holders of at least a majority in principal amount of the Outstanding
Securities of such series shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such term,
provision or condition, but no such waiver shall extend to or affect such term,
provision or condition except to the extent so expressly waived, and, until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.

      to Redeem; Notice to Trustee.

            


    

    


    The
election of the Company to redeem any Securities shall be evidenced by a Board
Resolution or in another manner specified as contemplated by Section 3.1 for
such Securities.  In case of any redemption at the election of the
Company of less than all the Securities of any series (including any such
redemption affecting only a single Security), the Company shall, at least 45
days prior to the Redemption Date fixed by the Company (unless a shorter notice
shall be satisfactory to the Trustee), notify the Trustee of such Redemption
Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed.  In the
case of any redemption of Securities prior to the expiration of any restriction
on such redemption provided in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish the Trustee with an Officers’ Certificate
evidencing compliance with such restriction.

    


    
      	
              Section
      11.3

            	
              Selection
      by Trustee of Securities to Be
Redeemed.

            


    

    


    If less
than all the Securities of any series are to be redeemed (unless all the
Securities of such series and of a specified tenor are to be redeemed or unless
such redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 45 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of such series not previously
called for redemption, by lot, or in the Trustee’s discretion, on a pro-rata
basis, provided that the unredeemed portion of the principal amount of any
Security shall be in an authorized denomination (which shall not be less than
the minimum authorized denomination) for such Security.  If less than
all the Securities of such series and of a specified tenor are to be redeemed
(unless such redemption affects only a single Security), the particular
Securities to be redeemed shall be selected not more than 45 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
and specified tenor not previously called for redemption in accordance with the
preceding sentence.

    


    If any
Security selected for partial redemption is converted in part before termination
of the conversion right with respect to the portion of the Security so selected,
the converted portion of such Security shall be deemed (so far as may be) to be
the portion selected for redemption.  Securities that have been
converted during a selection of Securities to be redeemed shall be treated by
the Trustee as Outstanding for the purpose of such selection.

    


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

    


    The
provisions of the two preceding paragraphs shall not apply with respect to any
redemption affecting only a single Security, whether such Security is to be
redeemed in whole or in part.  In the case of any such redemption in
part, the unredeemed portion of the principal amount of the Security shall be in
an authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security.

    


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

period is specified in the Securities to be redeemed, to each Holder of
Securities to be redeemed, at its address appearing in the Security

      may be placed only on the other identification numbers printed on the

    On or
prior to any Redemption Date, the Company shall deposit with the Trustee or with
a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate
and hold in trust as provided in Section 10.3) an amount of money sufficient to
pay the Redemption Price of, and (except if the Redemption Date shall be an
Interest Payment Date) accrued interest on, all the Securities which are to be
redeemed on that date.

    


    If any
Security called for redemption is converted, any money deposited with the
Trustee or with a Paying Agent or so segregated and held in trust for the
redemption of such Security shall (subject to the right of any Holder of such
Security to receive interest as provided in the last paragraph of Section 3.7)
be paid to the Company on Company Request, or if then held by the Company, shall
be discharged from such trust.

    Notice of
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified, and from and after such date (unless the Company shall
default in the payment of the Redemption Price and accrued interest) such
Securities shall cease to bear interest.  Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be
paid by the Company at the Redemption Price, together with accrued interest to
the Redemption Date; provided, however, that, unless otherwise specified as
contemplated by Section 3.1, installments of interest whose Stated Maturity is
on or prior to the Redemption Date will be payable to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 3.7.

    


    If any
Security called for redemption shall not be so paid upon surrender thereof for
redemption, the principal and any premium shall, until paid, bear interest from
the Redemption Date at the rate prescribed therefor in the
Security.

    Any
Security which is to be redeemed only in part shall be surrendered at a Place of
Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or its attorney
duly authorized in writing), and the Company 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 like tenor, of
any authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered.

      12.1

            	
              Applicability
      of Article.

            


    

    


    The
provisions of this Article shall be applicable to any sinking fund for the
retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities.

    


    The
minimum amount of any sinking fund payment provided for by the terms of any
Securities is herein referred to as a “mandatory sinking fund payment,” and any
payment in excess of such minimum amount provided for by the terms of such
Securities is herein referred to as an “optional sinking fund
payment.”  If provided for by the terms of any Securities, the cash
amount of any sinking fund payment may be subject to reduction as provided in
Section 12.2.  Each sinking fund payment shall be applied to the
redemption of Securities as provided for by the terms of such
Securities.


    
      
         


      

      
        -54-

      12.2

            	
              Satisfaction
      of Sinking Fund Payments with
Securities.

            


    

    


    The
Company (1) may deliver Outstanding Securities of a series (other than any
previously called for redemption) and (2) may apply as a credit Securities of a
series which 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 any
Securities of such series required to be made pursuant to the terms of such
Securities as and to the extent provided for by the terms of such Securities;
provided that the Securities to be so credited have not been previously so
credited.  The Securities to be so credited shall be received and
credited for such purpose by the Trustee at the Redemption Price, as specified
in the Securities so to be redeemed, for redemption through operation of the
sinking fund and the amount of such sinking fund payment shall be reduced
accordingly.

    


    
      	
              Section
      12.3

            	
              Redemption
      of Securities for Sinking Fund.

            


    

    


    Not fewer
than 60 days prior to each sinking fund payment date for any Securities, the
Company will deliver to the Trustee an Officers’ Certificate specifying the
amount of the next ensuing sinking fund payment for such Securities pursuant to
the terms of such Securities, 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 delivering and crediting Securities pursuant to Section 12.2 and
will also deliver to the Trustee any Securities to be so
delivered.  Not fewer than 30 days prior to 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 11.3 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 11.4.  Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 11.6 and 11.7.

  Defeasance.

            


    

    


    The
Company may elect, at its option at any time, to have Section 13.2 or Section
13.3 applied to any Securities or any series of Securities, as the case may be,
designated pursuant to Section 3.1 as being defeasible pursuant to such Section
13.2 or 13.3, in accordance with any applicable requirements provided pursuant
to Section 3.1 and upon compliance with the conditions set forth below in this
Article.  Any such election shall be evidenced by a Board Resolution
or in another manner specified as contemplated by Section 3.1 for such
Securities.

    Upon the
Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be, the Company shall be
deemed to have been discharged from its obligations, and the provisions of
Article 15 shall cease to be effective, with respect to such Securities as
provided in this Section on and after the date the conditions set forth in
Section 13.4 are satisfied (hereinafter called “Defeasance”).  For
this purpose, such Defeasance means that the Company shall be deemed to have
paid and discharged the entire indebtedness represented by such Securities and
to have satisfied all its other obligations under such Securities and this
Indenture insofar as such Securities are concerned (and the Trustee, at the
expense of the Company, shall execute proper instruments acknowledging the
same), subject to the following which shall survive until otherwise terminated

      rights of Holders of such Securities to receive, solely from the trust
      fund described in Section 13.4 and as more fully set forth in such
      Section, payments in respect of the principal of and any premium and
      interest on such Securities when payments are
  due,

              the
      Company’s obligations with respect to such Securities under Sections 3.4,
      3.5, 3.6, 10.2 and 10.3, and, if applicable, Article
  14,

              the
      rights, powers, trusts, duties and immunities of the Trustee hereunder,
      and

      Article.

            


    

    


    Subject
to compliance with this Article, the Company may exercise its option (if any) to
have this Section applied to any Securities notwithstanding the prior exercise
of its option (if any) to have Section 13.3 applied to such
Securities.

      Defeasance.

            


    

    


    Upon the
Company’s exercise of its option (if any) to have this Section applied to any
Securities or any series of Securities, as the case may be,

    


    
      	
               
      

            	
              (1)

            	
              the
      Company shall be released from its obligations under any covenants
      provided pursuant to Sections 3.1(19), 9.1(2) or 9.1(7) for the benefit of
      the Holders of such Securities,

            


    

    


    
      	
               
      

            	
              (2)

            	
              the
      occurrence of any event specified in Section 5.1(4) (with respect to any
      such covenants provided pursuant to Section 3.1(19), 9.1(2) or 9.1(7)) and
      the occurrence of any other Event of Default specified pursuant to Section
      3.1 shall be deemed not to be or result in an Event of Default,
      and

            


    

    


    
      	
               
      

            	
              (3)

            	
              the
      provisions of Article 15 shall cease to be
  effective,

            


    

    


    in each
case with respect to such Securities or any series of Securities as provided in
this Section on and after the date the conditions set forth in Section 13.4 are
satisfied (hereinafter called “Covenant Defeasance”).  For this
purpose, such Covenant Defeasance means that, with respect to such Securities,
the Company may omit to comply with and shall have no liability in respect of
any term, condition or limitation set forth in any such specified Section (to
the extent so specified in the case of Section 5.1(4) and the occurrence of any
Event of Default specified pursuant to Section 3.1) or Article 15, whether
directly or indirectly by reason of any reference elsewhere herein to any such
Section or Article or by reason of any reference in any such Section or Article
to any other provision herein or in any other document, but the remainder of
this Indenture and such Securities shall be unaffected thereby.

    in each
case sufficient, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, to pay and discharge, and which shall be applied by the Trustee (or any
such other qualifying trustee) to pay and discharge, the principal of and any
premium and interest on such Securities on the respective Stated Maturities, in
accordance with the terms of this Indenture and such Securities.

income tax purposes as a result of the deposit, Defeasance and discharge to be
effected with respect to such Securities and will be subject to Federal income
tax on the same amount, in the same manner and at the same times as would be the
case if such deposit, Defeasance and discharge were not to occur.

      regard to any such event specified in Sections 5.1(5) and (6), at any time
      on or prior to the 90th day after the date of such deposit (it being

thereunder.

    Section
13.5          Deposited Money,
U.S. Government Obligations and Foreign Government Obligations to be Held in
Trust; Miscellaneous Provisions.

    


    Subject
to the provisions of the last paragraph of Section 10.3, all money, U.S.
Government Obligations and Foreign Government Obligations (including the
proceeds thereof) deposited with the Trustee or other qualifying trustee (solely
for purposes of this Section and Section 13.6, the Trustee and any such other
trustee are referred to collectively as the “Trustee”) pursuant to Section 13.4
in respect of any Securities shall be held in trust and applied by the Trustee,
in accordance with the provisions of such Securities and this Indenture, to the
payment, either directly or through any such Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Holders of
such Securities, of all sums due and to become due thereon in respect of
principal and any premium and interest, but money so held in trust need not be
segregated from other funds except to the extent required by
law.  Money, U.S. Government Obligations and Foreign Government
Obligations so held in trust shall not be subject to the provisions of Article
15.

    


    The
Company shall pay and indemnify the Trustee against any tax, fee or other charge
imposed on or assessed against the U.S. Government Obligations or Foreign
Government Obligations deposited pursuant to Section 13.4 or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of Outstanding
Securities.

    


    Anything
in this Article to the contrary notwithstanding, the Trustee shall deliver or
pay to the Company from time to time upon Company Request any money, U.S.
Government Obligations or Foreign Government Obligations held by it as provided
in Section 13.4 with respect to any Securities which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect the
Defeasance or Covenant Defeasance, as the case may be, with respect to such
Securities.

    


    
      	
              Section
      13.6

            	
              Reinstatement.

            


    

    


    If the
Trustee or the Paying Agent is unable to apply any money in accordance with this
Article with respect to any Securities by reason of any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the obligations under this Indenture and such Securities
from which the Company has been discharged or released pursuant to Section 13.2
or 13.3 shall be revived and reinstated as though no deposit had occurred
pursuant to this Article with respect to such Securities, until such time as the
Trustee or Paying Agent is permitted to apply all money held in trust pursuant
to Section 13.5 with respect to such Securities in accordance with this Article;
provided, however, that if the Company makes any payment of principal of or any
premium or interest on any such Security following such reinstatement of its
obligations, the Company shall be subrogated to the rights (if any) of the
Holders of such Securities to receive such payment from the money so held in
trust.

    CONVERSION
OF SECURITIES

    


    
      	
              Section
      14.1

            	
              Applicability
      of Article.

            


    

    


    The
provisions of this Article shall be applicable to the Securities of any series
which are convertible into shares of Common Stock of the Company, and the
issuance of such shares of Common Stock upon the conversion of such Securities,
except as otherwise specified as contemplated by Section 3.1 for the Securities
of such series or in a supplemental indenture for Securities of such
series.

    


    
      	
              Section
      14.2

            	
              Exercise
      of Conversion Privilege.

            


    

    


    In order
to exercise a conversion privilege, the Holder of a Security of a series with
such a privilege shall surrender such Security to the Company at the office or
agency maintained for that purpose pursuant to Section 10.2, accompanied by a
duly executed conversion notice to the Company substantially in the form set
forth in Section 2.6 stating that the Holder elects to convert such Security or
a specified portion thereof.  Such notice shall also state, if
different from the name and address of such Holder, the name or names (with
address) in which the certificate or certificates for shares of Common Stock,
which shall be issuable on such conversion, shall be
issued.  Securities surrendered for conversion shall (if so required
by the Company or the Trustee) be duly endorsed by or accompanied by instruments
of transfer in forms satisfactory to the Company and the Trustee duly executed
by the Holder or its attorney duly authorized in writing.  As promptly
as practicable after the receipt of such notice and of any payment required
pursuant to a Board Resolution and, subject to Section 3.3, set forth, or
determined in the manner provided, in an Officers’ Certificate, or established
in one or more indentures supplemental hereto setting forth the terms of such
series of Security, and the surrender of such Security in accordance with such
reasonable regulations as the Company may prescribe, the Company shall issue and
shall deliver, at the office or agency at which such Security is surrendered, to
such Holder or on its written order, a certificate or certificates for the
number of full shares of Common Stock issuable upon the conversion of such
Security (or specified portion thereof), in accordance with the provisions of
such Board Resolution, Officers’ Certificate or supplemental indenture, and cash
as provided therein in respect of any fractional share of such Common Stock
otherwise issuable upon such conversion.  Such conversion shall be
deemed to have been effected immediately prior to the close of business on the
date on which such notice and such payment, if required, shall have been
received in proper order for conversion by the Company and such Security shall
have been surrendered as aforesaid (unless such Holder shall have so surrendered
such Security and shall have instructed the Company to effect the conversion on
a particular date following such surrender and such Holder shall be entitled to
convert such Security on such date, in which case such conversion shall be
deemed to be effected immediately prior to the close of business on such date)
and at such time the rights of the Holder of such Security as such Security
Holder shall cease and the person or persons in whose name or names any
certificate or certificates for shares of Common Stock of the Company shall be
issuable upon such conversion shall be deemed to have become the Holder or
Holders of record of the shares represented thereby.  Except as set
forth above and subject to the final paragraph of Section 3.7, no payment or
adjustment shall be made upon any conversion on account of any interest accrued
on the Securities (or any part thereof) surrendered for conversion or on account
of any dividends on the Common Stock of the Company issued upon such
conversion.

    In the
case of any Security which is converted in part only, upon such conversion the
Company shall execute and the Trustee shall authenticate and deliver to or on
the order of the Holder thereof, at the expense of the Company, a new Security
or Securities of the same series, of authorized denominations, in aggregate
principal amount equal to the unconverted portion of such Security.

    


    
      	
              Section
      14.3

            	
              No
      Fractional Shares.

            


    

    


    No
fractional share of Common Stock of the Company shall be issued upon conversions
of Securities of any series.  If more than one Security shall be
surrendered for conversion at one time by the same Holder, the number of full
shares which shall be issuable upon conversion shall be computed on the basis of
the aggregate principal amount of the Securities (or specified portions thereof
to the extent permitted hereby) so surrendered.  If, except for the
provisions of this Section 14.3, any Holder of a Security or Securities would be
entitled to a fractional share of Common Stock of the Company upon the
conversion of such Security or Securities, or specified portions thereof, the
Company shall pay to such Holder an amount in cash equal to the current market
value of such fractional share computed, (i) if such Common Stock is listed or
admitted to unlisted trading privileges on a national securities exchange or
market, on the basis of the last reported sale price regular way on such
exchange or market on the last trading day prior to the date of conversion upon
which such a sale shall have been effected, or (ii) if such Common Stock is not
at the time so listed or admitted to unlisted trading privileges on a national
securities exchange or market, on the basis of the average of the bid and asked
prices of such Common Stock in the over- the-counter market, on the last trading
day prior to the date of conversion, as reported by the National Quotation
Bureau, Incorporated or similar organization if the National Quotation Bureau,
Incorporated is no longer reporting such information, or if not so available,
the fair market price as determined by the Board of Directors.  For
purposes of this Section, “trading day” shall mean each Monday, Tuesday,
Wednesday, Thursday and Friday other than any day on which the Common Stock is
not traded on the Nasdaq National Market, or if the Common Stock is not traded
on the Nasdaq National Market, on the principal exchange or market on which the
Common Stock is traded or quoted.

      14.4

            	
              Adjustment
      of Conversion Price or Conversion
Rate.

            


    

    


    The
conversion price or conversion rate, as the case may be, of Securities of any
series that is convertible into Common Stock of the Company shall be adjusted
for any stock dividends, stock splits, reclassifications, combinations or
similar transactions in accordance with the terms of the supplemental indenture
or Board Resolutions setting forth the terms of the Securities of such
series.

    


    Whenever
the conversion price or conversion rate, as the case may be, is adjusted, the
Company shall compute the adjusted conversion price or conversion rate, as the
case may be, in accordance with terms of the applicable Board Resolution or
supplemental indenture and shall prepare an Officers’ Certificate setting forth
the adjusted conversion price or conversion rate, as the case may be, and
showing in reasonable detail the facts upon which such adjustment is based, and
such certificate shall forthwith be filed at each office or agency maintained
for the purpose of conversion of Securities pursuant to Section 10.2 and, if
different, with the Trustee.  The Company shall forthwith cause a
notice setting forth the adjusted conversion price or conversion rate, as the
case may be, to be mailed, first class postage prepaid, to each Holder of
Securities of such series at its address appearing on the Security Register and
to any conversion agent other than the Trustee.

              (1)

            	
              the

      Stock payable otherwise than in cash out of its retained earnings (other
      than a dividend for which approval of any shareholders of the Company is
      required) that would require an adjustment pursuant to Section 14.4;

      rights (other than any such grant for which approval of any shareholders
      of the Company is required); or

      any reclassification of the Common Stock of the Company (other than a
      subdivision or combination of its outstanding shares of Common Stock, or
      of any consolidation, merger or share exchange to which the Company is a
      party and for which approval of any shareholders of the Company is
      required), or of the sale of all or substantially all of the assets of the

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

            


    

    


    then the
Company shall cause to be filed with the Trustee, and shall cause to be mailed
to all Holders at their last addresses as they shall appear in the Security
Register, at least 20 days (or 10 days in any case specified in clause (1) or
(2) above) prior to the applicable record date hereinafter specified, a notice
stating (i) the date on which a record is to be taken for the purpose of such
dividend, distribution, rights, options or warrants, or, if a record is not to
be taken, the date as of which the holders of Common Stock of record to be
entitled to such dividend, distribution, rights, options or warrants are to be
determined, or (ii) the date on which such reclassification, consolidation,
merger, share exchange, sale, dissolution, liquidation or winding up is expected
to become effective, and the date as of which it is expected that holders of
Common Stock of record shall be entitled to exchange their shares of Common
Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, share exchange, sale, dissolution,
liquidation or winding up.  If at any time the Trustee shall not be
the conversion agent, a copy of such notice shall also forthwith be filed by the
Company with the Trustee.

provided in the next sentence, the Company will pay any and all taxes that may
be payable in respect of the issue or delivery of shares of its Common Stock on
conversion of Securities pursuant hereto.  The Company shall not,
however, be required to pay any tax which may be payable in respect of any
transfer involved in the issue and delivery of shares of its Common Stock in a
name other than that of the Holder of the Security or Securities to be
converted, and no such issue or delivery shall be made unless and until the
person requesting such issue has paid to the Company the amount of any such tax,
or has established, to the satisfaction of the Company, that such tax has been
paid.

duly and validly issued and fully paid and nonassessable.

              Provision
      in Case of Consolidation, Merger or Sale of
  Assets.

            


    

    


    In case
of any consolidation or merger of the Company with or into any other Person, any
merger of another Person with or into the Company (other than a merger which
does not result in any reclassification, conversion, exchange or cancellation of
outstanding shares of Common Stock of the Company) or any conveyance, sale,
transfer or lease of all or substantially all of the assets of the Company, the
Person formed by such consolidation or resulting from such merger or which
acquires such assets, as the case may be, shall execute and deliver to the
Trustee a supplemental indenture providing that the Holder of each Security of a
series then Outstanding that is convertible into Common Stock of the Company
shall have the right thereafter (which right shall be the exclusive conversion
right thereafter available to said Holder), during the period such Security
shall be convertible, to convert such Security only into the kind and amount of
securities, cash and other property receivable upon such consolidation, merger,
conveyance, sale, transfer or lease by a holder of the number of shares of
Common Stock of the Company into which such Security might have been converted
immediately prior to such consolidation, merger, conveyance, sale, transfer or
lease, assuming such holder of Common Stock of the Company (i) is not a Person
with which the Company consolidated or merged with or into or which merged into
or with the Company or to which such conveyance, sale, transfer or lease was
made, as the case may be (a “Constituent Person”), or an Affiliate of a
Constituent Person and (ii) failed to exercise his rights of election, if any,
as to the kind or amount of securities, cash and other property receivable upon
such consolidation, merger, conveyance, sale, transfer or lease (provided that
if the kind or amount of securities, cash and other property receivable upon
such consolidation, merger, conveyance, sale, transfer, or lease is not the same
for each share of Common Stock of the Company held immediately prior to such
consolidation, merger, conveyance, sale, transfer or lease by others than a
Constituent Person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised (“Non-electing Share”), then for the
purpose of this Section 14.9 the kind and amount of securities, cash and other
property receivable upon such consolidation, merger, conveyance, sale, transfer
or lease by the holders of each Non-electing Share shall be deemed to be the
kind and amount so receivable per share by a plurality of the Non-electing
Shares).  Such supplemental indenture shall provide for adjustments
which, for events subsequent to the effective date of such supplemental
indenture, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article or in accordance with the terms of the
supplemental indenture or Board Resolutions setting forth the terms of such
adjustments.  The above provisions of this Section 14.9 shall
similarly apply to successive consolidations, mergers, conveyances, sales,
transfers or leases.  Notice of the execution of such a supplemental
indenture shall be given by the Company to the Holder of each Security of a
series that is convertible into Common Stock of the Company as provided in
Section 1.6 promptly upon such execution.

    Neither
the Trustee nor any conversion agent, if any, shall be under any responsibility
to determine the correctness of any provisions contained in any such
supplemental indenture relating either to the kind or amount of shares of stock
or other securities or property or cash receivable by Holders of Securities of a
series convertible into Common Stock of the Company upon the conversion of their
Securities after any such consolidation, merger, conveyance, transfer, sale or
lease or to any such adjustment, but may accept as conclusive evidence of the
correctness of any such provisions, and shall be protected in relying upon, an
Opinion of Counsel with respect thereto, which the Company shall cause to be
furnished to the Trustee upon request.

      of Trustee Regarding Conversion.

            


    

    


    Neither
the Trustee nor any conversion agent shall at any time be under any duty or
responsibility to any Holder of Securities of any series that is convertible
into Common Stock of the Company to determine whether any facts exist which may
require any adjustment of the conversion price or conversion rate, as the case
may be, or with respect to the nature or extent of any such adjustment when
made, or with respect to the method employed, whether herein or in any
supplemental indenture, any resolutions of the Board of Directors or written
instrument executed by one or more officers of the Company provided to be
employed in making the same.  Neither the Trustee nor any conversion
agent shall be accountable with respect to the validity or value (or the kind or
amount) of any shares of Common Stock of the Company, or of any securities or
property, which may at any time be issued or delivered upon the conversion of
any Securities and neither the Trustee nor any conversion agent makes any
representation with respect thereto.  Subject to the provisions of
Section 6.1, neither the Trustee nor any conversion agent shall be responsible
for any failure of the Company to issue, transfer or deliver any shares of its
Common Stock or stock certificates or other securities or property upon the
surrender of any Security for the purpose of conversion or to comply with any of
the covenants of the Company contained in this Article 14 or in the applicable
supplemental indenture, resolutions of the Board of Directors or written
instrument executed by one or more duly authorized officers of the
Company.

    Except as
otherwise provided in a supplemental indenture or pursuant to Section 3.1, the
Company covenants and agrees, and each Holder of Securities issued hereunder by
its acceptance thereof likewise covenants and agrees, that all Securities shall
be issued subject to the provisions of this Article 15; and each Person holding
any Security, whether upon original issue or upon transfer, assignment or
exchange thereof, accepts and agrees to be bound by such
provisions.

    The
payment of the principal of, premium, if any, and interest on all Securities
(including, but not limited to, the redemption price with respect to the
Securities called for redemption in accordance with Article 11 as provided in
the Indenture) issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and subject in right of payment to the
prior payment in full of all Senior Debt, whether outstanding at the date of
this Indenture or thereafter incurred.

    


    No

    No
payment shall be made with respect to the principal of, or premium, if any, or
interest on the Securities (including, but not limited to, the redemption price
with respect to the Securities to be called for redemption in accordance with
Article 11 as provided in the Indenture), except payments and distributions made
by the Trustee as permitted by the first or second paragraph of Section 15.5,
if:

    


    (i) a
default in the payment of principal, premium, if any, interest, rent or other
obligations due on any Senior Debt occurs and is continuing (or, in the case of
Senior Debt for which there is a period of grace, in the event of such a default
that continues beyond the period of grace, if any, specified in the instrument
or lease evidencing such Senior Debt) (a “Payment Default”), unless and until
such default shall have been cured or waived or shall have ceased to exist;
or

    


    (ii) a
default, other than a Payment Default, on any Designated Senior Debt occurs and
is continuing that then permits holders of such Designated Senior Debt to
accelerate its maturity and the Trustee receives a notice of the default (a
“Payment Blockage Notice”) from a holder of Designated Senior Debt, a
Representative of Designated Senior Debt or the Company (a “Non-Payment
Default”).

    


    If the
Trustee receives any Payment Blockage Notice pursuant to clause (ii) above, no
subsequent Payment Blockage Notice shall be effective for purposes of this
Section unless and until at least 365 days shall have elapsed since the initial
effectiveness of the immediately prior Payment Blockage Notice.  No
Non-Payment Default that existed or was continuing on the date of delivery of
any Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

    


    The
Company may and shall resume payments on and distributions in respect of the
Securities upon the earlier of:

    


    
      	
               
      

            	
              (1)

            	
              in
      the case of any Payment Default, the date upon which the Payment Default
      is cured or waived or ceases to exist,

              (2)

            	
              in
      the case of a Non-Payment Default, the earlier of (a) the date upon which
      such Non-Payment Default is cured, waived or ceases to exist or (b) 179
      days after the date on which the applicable Payment Blockage Notice is
      received by the Trustee, unless this Article 15 otherwise prohibits the
      payment or distribution at such
time.

    Upon any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, to creditors upon any dissolution or
winding-up or liquidation or reorganization of the Company, whether voluntary or
involuntary or in bankruptcy, insolvency, reorganization, liquidation,
receivership or other proceedings, or upon an assignment for the benefit of
creditors or any marshalling of the assets and liabilities of the Company, or
otherwise, all amounts due or to become due upon all Senior Debt shall first be
paid in full in cash or other payment satisfactory to the holders of such Senior
Debt, or payment thereof in accordance with its terms provided for in cash or
other payment satisfactory to the holders of such Senior Debt, before any
payment is made on account of the principal of, premium, if any, or interest on
the Securities (except payments made pursuant to Article 4 from monies deposited
with the Trustee pursuant thereto prior to commencement of proceedings for such
dissolution, winding-up, liquidation, reorganization, assignment for the benefit
of creditors or the marshalling of assets and liabilities of the Company); and
upon any such dissolution, winding-up, liquidation, reorganization, assignment
for the benefit of creditors or marshalling of assets and liabilities of the
Company or bankruptcy, insolvency, receivership or other proceeding, any payment
by the Company, or distribution of assets of the Company of any kind or
character, whether in cash, property or securities, to which the Holders of the
Securities or the Trustee would be entitled, except for the provision of this
Article 15, shall (except as aforesaid) be paid by the Company or by any
receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the Holders of the Securities or by
the Trustee under this Indenture if received by them or it, directly to the
holders of Senior Debt (pro rata to such holders on the basis of the respective
amounts of Senior Debt held by such holders, or as otherwise required by law or
a court order) or their Representative or Representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing any
Senior Debt may have been issued, as their respective interests may appear, to
the extent necessary to pay all Senior Debt in full, in cash or other payment
satisfactory to the holders of such Senior Debt, after giving effect to any
concurrent payment or distribution to or for the holders of Senior Debt, before
any payment or distribution or provision therefor is made to the Holders of the
Securities or to the Trustee.

    


    For
purposes of this Article 15, the words, “cash, property or securities” shall not
be deemed to include shares of stock of the Company as reorganized or
readjusted, or securities of the Company or any other corporation provided for
by a plan of reorganization or readjustment, the payment of which is
subordinated at least to the extent provided in this Article 15 with respect to
the Securities to the payment of all Senior Debt which may at the time be
outstanding; provided that (i) the Senior Debt is assumed by the new
corporation, if any, resulting from any reorganization or readjustment, and (ii)
the rights of the holders of Senior Debt (other than leases which are not
assumed by the Company or the new corporation, as the case may be) are not,
without the consent of such holders, altered by such reorganization or
readjustment.  The consolidation of the Company with, or the merger of
the Company into, another corporation or the liquidation or dissolution of the
Company following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another corporation upon the terms and
conditions provided for in Article 8 shall not be deemed a dissolution,
winding-up, liquidation or reorganization for the purposes of this Section 15.2
if such other corporation shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions stated in Article
8.

    


    In the
event of the acceleration of the Securities because of an Event of Default, no
payment or distribution shall be made to the Trustee or any Holder of Securities
in respect of the principal of, premium, if any, or interest on the Securities
(including, but not limited to, the redemption price with respect to the
Securities called for redemption in accordance with Article 11 as provided in
the Indenture), except payments and distributions made by the Trustee as
permitted by the first or second paragraph of Section 15.5, until all Senior
Debt has been paid in full in cash or other payment satisfactory to the holders
of Senior Debt or such acceleration is rescinded in accordance with the terms of
this Indenture.  If payment of the Securities is accelerated because
of an Event of Default, the Company shall promptly notify holders of Senior Debt
of the acceleration.

    In the
event that, notwithstanding the foregoing provisions, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities (including, without limitation, by way of setoff or
otherwise), prohibited by the foregoing, shall be received by the Trustee or the
Holders of the Securities before all Senior Debt is paid in full in cash or
other payment satisfactory to the holders of such Senior Debt, or provision is
made for such payment thereof in accordance with its terms in cash or other
payment satisfactory to the holders of such Senior Debt, such payment or
distribution shall be held in trust for the benefit of and shall be paid over or
delivered to the holders of Senior Debt or their Representative or
Representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Debt may have been issued, as their
respective interests may appear, as calculated by the Company, for application
to the payment of all Senior Debt remaining unpaid to the extent necessary to
pay all Senior Debt in full in cash or other payment satisfactory to the holders
of such Senior Debt, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Debt.

    


    Nothing
in this Section 15.2 shall apply to claims of, or payments to, the Trustee under
or pursuant to Section 6.7.  This Section 15.2 shall be subject to the
further provisions of Section 15.5.

      of Securities.

            


    

    


    Subject
to the payment in full of all Senior Debt, the rights of the Holders of the
Securities shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Debt pursuant to the provisions of this
Article 15 (equally and ratably with the holders of all indebtedness of the
Company which by its express terms is subordinated to other indebtedness of the
Company to substantially the same extent as the Securities are subordinated and
is entitled to like rights of subrogation) to the rights of the holders of
Senior Debt to receive payments or distributions of cash, property or securities
of the Company applicable to the Senior Debt until the principal, premium, if
any, and interest on the Securities shall be paid in full; and, for the purposes
of such subrogation, no payments or distributions to the holders of the Senior
Debt of any cash, property or securities to which the Holders of the Securities
or the Trustee would be entitled except for the provisions of this Article 15,
and no payment over pursuant to the provisions of this Article 15, to or for the
benefit of the holders of Senior Debt by Holders of the Securities or the
Trustee, shall, as between the Company, its creditors other than holders of
Senior Debt, and the Holders of the Securities, be deemed to be a payment by the
Company to or on account of the Senior Debt; and no payments or distributions of
cash, property or securities to or for the benefit of the Holders of the
Securities pursuant to the subrogation provisions of this Article 15, which
would otherwise have been paid to the holders of Senior Debt shall be deemed to
be a payment by the Company to or for the account of the
Securities.  It is understood that the provisions of this Article 15
are and are intended solely for the purposes of defining the relative rights of
the Holders of the Securities, on the one hand, and the holders of the Senior
Debt, on the other hand.

    


    Nothing
contained in this Article 15 or elsewhere in this Indenture or in the Securities
is intended to or shall impair, as among the Company, its creditors other than
the holders of Senior Debt, and the Holders of the Securities, the obligation of
the Company, which is absolute and unconditional, to pay to the Holders of the
Securities the principal of (and premium, if any) and interest on the Securities
as and when the same shall become due and payable in accordance with their
terms, or is intended to or shall affect the relative rights of the Holders of
the Securities and creditors of the Company other than the holders of the Senior
Debt, nor shall anything herein or therein prevent the Trustee or the Holder of
any Security from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article 15 of the holders of Senior Debt in respect of cash, property or
securities of the Company received upon the exercise of any such
remedy.

the Trustee, subject to the provisions of Section 6.1, and the Holders of the
Securities shall be entitled to rely upon any order or decree made by any court
of competent jurisdiction in which such bankruptcy, dissolution, winding-up,
liquidation or reorganization proceedings are pending, or a certificate of the
receiver, trustee in bankruptcy, liquidating trustee, agent or other person
making such payment or distribution, delivered to the Trustee or to the Holders
of the Securities, for the purpose of ascertaining the persons entitled to
participate in such distribution, the holders of the Senior Debt and other
indebtedness of the Company, the amount thereof or payable thereon and all other
facts pertinent thereto or to this Article 15.

    Each
Holder of a Security by the holder’s acceptance thereof authorizes and directs
the Trustee on the holder’s behalf to take such action as may be necessary or
appropriate to effectuate the subordination as provided in this Article 15 and
appoints the Trustee to act as the holder’s attorney-in-fact for any and all
such purposes.  If the Trustee does not file a proper proof of claim
or proof of debt in the form required in any proceeding referred to in Section
5.4 hereof at least 30 days before the expiration of the time to file such
claim, the holders of any Senior Debt or their representatives are hereby
authorized to file an appropriate claim for and on behalf of the Holders of the
Securities.

    The
Company shall give prompt written notice in the form of an Officers’ Certificate
to a Responsible Officer of the Trustee and to any Paying Agent of any fact
known to the Company which would prohibit the making of any payment of monies to
or by the Trustee or any Paying Agent in respect of the Securities pursuant to
the provisions of this Article 15.  Notwithstanding the provisions of
this Article 15 or any other provision of this Indenture, the Trustee shall not
be charged with knowledge of the existence of any facts which would prohibit the
making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article 15, unless and until a
Responsible Officer of the Trustee shall have received written notice thereof at
the Corporate Trust Office from the Company (in the form of an Officers’
Certificate) or a Representative or a holder or holders of Senior Debt or from
any trustee therefor; and before the receipt of any such written notice, the
Trustee, subject to the provisions of Section 6.1, shall be entitled in all
respects to assume that no such facts exist; provided that if on a date not
fewer than two Business Days prior to the date upon which by the terms hereof
any such monies may become payable for any purpose (including, without
limitation, the payment of the principal of, or premium, if any, or interest on
any Security) the Trustee shall not have received, with respect to such monies,
the notice provided for in this Section 15.5, then, anything herein contained to
the contrary notwithstanding, the Trustee shall have full power and authority to
receive such monies and to apply the same to the purpose for which they were
received, and shall not be affected by any notice to the contrary which may be
received by it on or after such prior date.

    


    Notwithstanding
anything in this Article 15 to the contrary, nothing shall prevent any payment
by the Trustee to the Holders of monies deposited with it pursuant to Section
4.1, and any such payment shall not be subject to the provisions of Section 15.1
or 15.2.

    


    The
Trustee, subject to the provisions of Section 6.1, shall be entitled to rely on
the delivery to it of a written notice by a Representative or a person
representing himself to be a holder of Senior Debt (or a trustee on behalf of
such holder) to establish that such notice has been given by a Representative or
a holder of Senior Debt or a trustee on behalf of any such holder or
holders.  The Trustee shall not be required to make any payment or
distribution to or on behalf of a holder of Senior Debt pursuant to this Article
15 unless it has received satisfactory evidence as to the amount of Senior Debt
held by such person, the extent to which such person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such person under this Article 15.

    The
Trustee in its individual capacity shall be entitled to all the rights set forth
in this Article 15 in respect of any Senior Debt at any time held by it, to the
same extent as any other holder of Senior Debt, and nothing in this Indenture
shall deprive the Trustee of any of its rights as such holder.

    


    With
respect to the holders of Senior Debt, the Trustee undertakes to perform or to
observe only such of its covenants and obligations as are specifically set forth
in this Article 15, and no implied covenants or obligations with respect to the
holders of Senior Debt shall be read into this Indenture against the
Trustee.  The Trustee shall not be deemed to owe any fiduciary duty to
the holders of Senior Debt and, subject to the provisions of Section 6.1, the
Trustee shall not be liable to any holder of Senior Debt (i) for any failure to
make any payments or distributions to such holders or (ii) if it shall pay over
or deliver to Holders of Securities, the Company or any other Person money or
assets to which any holder of Senior Debt shall be entitled by virtue of this
Article 15 or otherwise.

              No
      Impairment of Subordination.

            


    

    


    No right
of any present or future holder of any Senior Debt to enforce subordination as
herein provided shall at any time in any way be prejudiced or impaired by any
act or failure to act on the part of the Company or by any act or failure to
act, in good faith, by any such holder, or by any noncompliance by the Company,
the Trustee or any Holder of Securities with the terms, provisions and covenants
of this Indenture, regardless of any knowledge thereof which any such holder may
have or otherwise be charged with.

    


    
      	
              Section
      15.8

            	
              Certain
      Conversions/Exchanges Deemed
Payment.

            


    

    


    For the
purposes of this Article 15 only, (1) the issuance and delivery of junior
securities upon conversion or exchange of Securities in accordance with Article
14 or otherwise (except upon conversion of the Securities in accordance with
their terms) shall not be deemed to constitute a payment or distribution on
account of the principal of (or premium, if any) or interest on Securities or on
account of the purchase or other acquisition of Securities, and (2) the payment,
issuance or delivery of cash (except in satisfaction of fractional shares
pursuant to Section 14.3), property or securities (other than junior securities)
upon conversion or exchange of a Security shall be deemed to constitute payment
on account of the principal of such Security.  For the purposes of
this Section 15.8, the term “junior securities” means (a) shares of any stock of
any class of the Company, or (b) securities of the Company which are
subordinated in right of payment to all Senior Debt which may be outstanding at
the time of issuance or delivery of such securities to substantially the same
extent as, or to a greater extent than, the Securities are so subordinated as
provided in this Article.  Nothing contained in this Article 15 or
elsewhere in this Indenture or in the Securities is intended to or shall impair,
as among the Company, its creditors other than holders of Senior Debt and the
Holders of Securities, the right, which is absolute and unconditional, of the
Holder of any Security to convert such Security in accordance with Article
14.

    If at any
time any Paying Agent other than the Trustee shall have been appointed by the
Company and be then acting hereunder, the term “Trustee” as used in this Article
shall (unless the context otherwise requires) be construed as extending to and
including such Paying Agent within its meaning as fully for all intents and
purposes as if such Paying Agent were named in this Article in addition to or in
place of the Trustee; provided, however, that the first paragraph of Section
15.5 shall not apply to the Company or any Affiliate of the Company if the
Company or such Affiliate acts as Paying Agent.

    


    The
Trustee shall not be responsible for the actions or inactions of any other
Paying Agents (including the Company if acting as its own Paying Agent) and
shall have no control of any funds held by such other Paying
Agents.

              Senior
      Debt Entitled to Rely.

            


    

    


    The
holders of Senior Debt (including, without limitation, Designated Senior Debt)
shall have the right to rely upon this Article 15, and no amendment or
modification of the provisions contained herein shall diminish the rights of
such holders unless such holders shall have agreed in writing
thereto.

    


    
      	
              Section
      15.11

            	
              Reliance
      on Judicial Order or Certificate of Liquidating
  Agent.

            


    

    


    Upon any
payment or distribution of assets of the Company referred to in this Article,
the Trustee and the Holders shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such dissolution,
winding up, liquidation, reorganization, assignment for the benefit of creditors
or marshalling of assets and liabilities of the Company or bankruptcy,
insolvency, receivership or other like proceeding is pending, or a certificate
of the trustee in bankruptcy, liquidating trustee, custodian, receiver, assignee
for the benefit of creditors, agent or other person making such payment or
distribution, delivered to the Trustee or to the Holders, for the purpose of
ascertaining the persons entitled to participate in such payment or
distribution, the holders of Senior Debt and other indebtedness of the Company,
the amount thereof or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Article.

              Trust
      Monies Not Subordinated.

            


    

    


    Notwithstanding
anything contained herein to the contrary, payments from money, U.S. Government
Obligations and/or Foreign Government Obligations held in trust under Article 4
or Article 13 by the Trustee for the payment of the principal of, premium, if
any, and interest on the Securities shall not be subordinated to the prior
payment in full of any Senior Debt of the Company or subject to the restrictions
set forth in this Article 15, and none of the Holders shall be obligated to pay
over any such amount to the Company or any holder of Senior Debt of the Company
or any other creditor of the Company.
