Series. All Securities of a Series shall be identical except as may be set forth
in a Board Resolution, a supplemental indenture or an Officers’ Certificate
detailing the adoption of the terms thereof pursuant to the authority granted
under a Board Resolution. In the case of Securities of a Series to be issued
from time to time, the Board Resolution, Officers’ Certificate or supplemental
indenture may provide for the method by which specified terms (such as interest
rate, Stated Maturity, record date or date from which interest shall accrue) are
to be determined. Securities may differ between Series in respect of any
matters, PROVIDED, that all Series of Securities shall be equally and ratably
entitled to the benefits of the Indenture.

    All
Securities of any one Series need not be issued at the same time, and may be
issued from time to time, consistent with the terms of this Indenture, if so
provided by or pursuant to the Board Resolution, supplemental indenture or
Officers’ Certificate referred to above, however, the authorized principal
amount of any Series may not be increased to provide for issuances of additional
Securities of such Series, unless otherwise provided in such Board Resolution,
supplemental indenture or Officers’ Certificate.

     

    
      	
              2.3

            	
              EXECUTION
      AND AUTHENTICATION.

            


    

     

    The
Securities shall be executed on behalf of the Company by two Officers of the
Company or an Officer and an Assistant Secretary of the Company. Each such
signature may be either manual or facsimile. The Company’s seal may be
impressed, affixed, imprinted or reproduced on the Securities and may be in
facsimile form.

     

    If an
Officer whose signature is on a Security no longer holds that office at the time
the Security is authenticated, the Security shall nevertheless be
valid.

     

    A
Security shall not be valid until authenticated by the manual signature of the
Trustee or an authenticating agent. The signature shall be conclusive evidence
that the Security has been authenticated under this Indenture. The Trustee shall
at any time, and from time to time, authenticate Securities for original issue
in the principal amount provided in the Board Resolution, supplemental indenture
hereto or Officers’ Certificate, upon receipt by the Trustee of a Company Order.
Such Company Order may authorize authentication and delivery pursuant to oral or
electronic instructions from the Company or its duly authorized agent or agents,
which oral instructions shall be promptly confirmed in writing. Each Security
shall be dated the date of its authentication.

    The
aggregate principal amount of Securities of any Series outstanding at any time
may not exceed any limit upon the maximum principal amount for such Series set
forth in the Board Resolution, supplemental indenture hereto or Officers’
Certificate delivered pursuant to Section 2.2, except as provided in
Section 2.8.

     

    Prior to
the issuance of Securities of any Series, the Trustee shall have received and
(subject to Section 7.1) shall be fully protected in relying on:
(a) the Board Resolution, supplemental indenture hereto or Officers’
Certificate establishing the form of the Securities of that Series or of
Securities within that Series and the terms of the Securities of that Series or
of Securities within that Series, (b) an Officers’ Certificate complying
with Section 10.4, and (c) an Opinion of Counsel complying with
Section 10.4.

     

    The
Trustee shall have the right to decline to authenticate and deliver any
Securities of any Series: (a) if the Trustee, being advised in writing by
outside counsel, determines that such action may not lawfully be taken; or
(b) if the Trustee in good faith by its board of directors or trustees,
executive committee or a trust committee of directors and/or vice-presidents
shall reasonably determine that such action would expose the Trustee to personal
liability, or cause it to have a conflict of interest with respect to Holders of
any then outstanding Series of Securities.

     

    The
Trustee may appoint an authenticating agent acceptable to the Company to
authenticate Securities. An authenticating agent may authenticate Securities
whenever the Trustee may do so. Any appointment shall be evidenced by an
instrument signed by an authorized officer of the Trustee, a copy of which shall
be furnished to the Company. Each reference in this Indenture to authentication
by the Trustee includes authentication by such agent. An authenticating agent
has the same rights as an Agent to deal with the Company or an Affiliate of the
Company.

              REGISTRAR
      AND PAYING AGENT.

            


    

     

    The
Company shall maintain in each Place of Payment for any Series of Securities
(i) an office or agency where such Securities may be presented for
registration of transfer or for exchange (“Registrar”), (ii) an office or
agency where such Securities may be presented for payment (“Paying Agent”)
(PROVIDED that the Company shall at all times maintain a Paying Agent in the
Borough of Manhattan, City of New York, State of New York (the “New York Paying
Agent”), and PROVIDED, FURTHER, 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 register for the Securities
maintained by the Registrar), and (iii) an office or agency where notices
and demands to or upon the Company in respect of the Securities and this
Indenture may be served (“Service Agent”). The Registrar shall keep a register
of the Securities and of their transfer and exchange. The Company may have one
or more co-registrars and one or more additional paying agents. The Company
shall 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 to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the address of the Trustee as set forth in Section 10.2. If the
Company acts as Paying Agent, it shall segregate the money held by it for the
payment of principal of, and interest and premium, if any, on, the Securities
and hold it as a separate trust fund. The Company may change any Paying Agent,
Registrar, co-registrar or any other Agent without notice to any
Securityholder.

     

    The
Company may also from time to time designate one or more other offices or
agencies where the Securities 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 hereby
initially designates the Corporate Trust Office of the Trustee as such office of
the Company. The Company shall give prompt written notice to the Trustee of such
designation or rescission, and of any change in the location of any such other
office or agency.

     

    The
Company shall enter into an appropriate agency agreement with any Registrar or
Paying Agent not a party to this Indenture. The agreement shall implement the
provisions of this Indenture that relate to such Agent. The Company shall notify
the Trustee of the name and address of any such Agent. If the Company fails to
maintain a Registrar or Paying Agent, or agent for service of notices and
demands, or fails to give the foregoing notice, the Trustee shall act as such.
The Company hereby appoints the Trustee as the initial Registrar, Paying Agent
and Service Agent for each Series unless another Registrar, Paying Agent or
Service Agent, as the case may be, is appointed prior to the time Securities of
that Series are first issued. The Company designates ____________________, as
the New York Paying Agent, with offices at ____________________.

      AGENT TO HOLD ASSETS IN TRUST.

            


    

     

    The
Trustee as Paying Agent shall, and the Company shall require each Paying Agent
other than the Trustee to agree in writing that each Paying Agent shall, hold in
trust for the benefit of the Holders of any Series of Securities or the Trustee
all assets held by the Paying Agent for the payment of principal of, or interest
or premium, if any, on, such Series of Securities (whether such assets have been
distributed to it by the Company or any other obligor on such Series of
Securities), and the Company and the Paying Agent shall notify the Trustee in
writing of any Default by the Company (or any other obligor on such Series of
Securities) in making any such payment. The Company at any time may require a
Paying Agent to distribute all assets held by it to the Trustee and account for
any assets disbursed, and the Trustee may, at any time during the continuance of
any payment default with respect to any Series of Securities, upon written
request to a Paying Agent, require such Paying Agent to distribute all assets
held by it to the Trustee and to account for any assets distributed. Upon
distribution to the Trustee of all assets that shall have been delivered by the
Company to the Paying Agent, the Paying Agent shall have no further liability
for such assets.

              SECURITYHOLDER
      LISTS.

            


    

     

    The
Trustee shall preserve in as current a form as is reasonably practicable the
most recent list available to it of the names and addresses of Securityholders
of each Series of Securities. If the Trustee is not the Registrar, the Company
shall furnish to the Trustee as of each regular record date for the payment of
interest on the Securities of a Series and before each related Interest Payment
Date, and at such other times as the Trustee may request in writing, a list in
such form and as of such date as the Trustee may reasonably require of the names
and addresses of Securityholders of each Series of Securities.

              TRANSFER
      AND EXCHANGE.

            


    

     

    When
Securities of a Series are presented to the Registrar with a request to register
the transfer thereof, the Registrar shall register the transfer as requested if
the requirements of applicable law are met, and when such Securities of a Series
are presented to the Registrar with a request to exchange them for an equal
principal amount of other authorized denominations of Securities of the same
Series, the Registrar shall make the exchange as requested. To permit transfers
and exchanges, upon surrender of any Security for registration of transfer at
the office or agency maintained pursuant to Section 2.4, the Company shall
execute and the Trustee shall authenticate Securities at the Registrar’s
request.

     

    If
Securities are issued as Global Securities, the provisions of Section 2.15
shall apply.

     

    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 Registrar or a co-registrar) be duly
endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Registrar or a co-registrar, duly executed
by the Holder thereof or his attorney duly authorized in writing.

     

    Any
exchange or transfer shall be without charge, except that the Company may
require payment by the Holder of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation to a transfer or exchange,
but this provision shall not apply to any exchange pursuant to
Section 2.11, 3.6 or 8.5. The Trustee shall not be required to register
transfers of Securities of any Series, or to exchange Securities of any Series,
for a period of 15 days before the record date for selection for redemption
of such Securities. The Trustee shall not be required to exchange or register
transfers of Securities of any Series called or being called for redemption in
whole or in part, except the unredeemed portion of such Security being redeemed
in part.

      SECURITIES.

            


    

     

    If a
mutilated Security is surrendered to the Trustee, or if the Holder of a Security
presents evidence to the satisfaction of the Company and the Trustee that the
Security has been lost, destroyed or wrongfully taken, the Company shall issue
and the Trustee shall authenticate a replacement Security of the same Series and
of like tenor and principal amount and bearing a number not contemporaneously
outstanding. An indemnity bond may be required by the Company or the Trustee
that is sufficient in the reasonable judgment of the Company or the Trustee, as
the case may be, to protect the Company, the Trustee or any Agent from any loss
which any of them may suffer if a Security is replaced. The Company may charge
such Holder for the Company’s out-of-pocket expenses in replacing a Security,
including the fees and expenses of the Trustee. Every replacement Security shall
constitute an original additional 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.

              OUTSTANDING
      SECURITIES.

            


    

     

    Securities
outstanding at any time are all Securities authenticated by the Trustee, except
for those canceled by it, those delivered to it for cancellation and those
described in this Section 2.9 as not outstanding.

     

    If a
Security is replaced pursuant to Section 2.8 (other than a mutilated
Security surrendered for replacement), it ceases to be outstanding until the
Company and the Trustee receive proof satisfactory to each of them that the
replaced Security is held by a bona fide purchaser. A mutilated Security ceases
to be outstanding upon surrender of such Security and replacement thereof
pursuant to Section 2.8.

     

    If a
Paying Agent holds on a Redemption Date or the Stated Maturity money sufficient
to pay the principal of, premium, if any, and accrued interest on, Securities
payable on that date, and is not prohibited from paying such money to the
Holders thereof pursuant to the terms of this Indenture (PROVIDED, that if such
Securities are to be redeemed, notice of such redemption has been duly given
pursuant to this Indenture or provision therefor satisfactory to the Trustee has
been made), then on and after that date such Securities cease to be outstanding
and interest on them ceases to accrue.

     

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

      TREASURY SECURITIES DISREGARDED; DETERMINATION OF HOLDERS’
      ACTION.

            


    

     

    In
determining whether the Holders of the required aggregate principal amount of
the Securities of any Series have concurred in any direction, waiver or consent,
the Securities of any Series owned by the Company or any other obligor on such
Securities, or by any Affiliate of any of them, shall be disregarded, except
that for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Securities of such Series
which the Trustee actually knows are so owned shall be so disregarded.
Securities of such Series so owned which have been pledged in good faith shall
not be disregarded if the pledgee establishes to the satisfaction of the Trustee
the pledgee’s right so to act with respect to the Securities of such Series and
that the pledgee is not the Company or any other obligor on the Securities of
such Series, or an Affiliate of any of them.

      SECURITIES.

            


    

     

    Until
definitive Securities are ready for delivery, the Company may prepare and
execute, and the Trustee shall authenticate, temporary Securities. Temporary
Securities shall be substantially in the form, and shall carry all rights, of
definitive Securities, but may have variations that the Company considers
appropriate for temporary Securities. Without unreasonable delay, the Company
shall prepare and execute, and the Trustee shall authenticate, definitive
Securities in exchange for temporary Securities without charge to the
Holder.

    All
Securities surrendered for payment, redemption or 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 for
cancellation. 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. The Registrar and the Paying Agent shall forward to the
Trustee any Securities surrendered to them for transfer, exchange or payment.
The Trustee or, at the direction of the Trustee, the Registrar or the Paying
Agent, and no one else, shall cancel, and at the written request of the Company
shall dispose of, all Securities surrendered for transfer, exchange, payment or
cancellation. If the Company shall acquire any of the Securities, such
acquisition shall not operate as a redemption or satisfaction of the
Indebtedness represented by such Securities unless and until the same are
surrendered to the Trustee for cancellation pursuant to this Section 2.12.
No Securities shall be authenticated in lieu of or in exchange for any
Securities cancelled as provided in this Section 2.12, except as expressly
permitted by this Indenture.

    Except as
otherwise provided as contemplated by Section 2.2 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 is registered at the close of business
on the regular record date for such interest, as provided in the Board
Resolution, supplemental indenture hereto or Officers’ Certificate establishing
the terms of such Series.

     

    If the
Company defaults in a payment of interest on the Securities, it shall pay the
defaulted amounts, plus any interest payable on defaulted amounts pursuant to
Section 4.1, to the Persons who are Securityholders on a subsequent special
record date, which date shall be the 15th day next preceding the date fixed by
the Company for the payment of defaulted interest, or the next succeeding
Business Day if such date is not a Business Day. At least 15 days before
the special record date, the Company shall mail or cause to be mailed to each
Securityholder, with a copy to the Trustee, a notice that states the special
record date, the payment date and the amount of defaulted interest, and interest
payable on such defaulted interest, if any, to be paid.

     

    Except as
otherwise specified as contemplated by Section 2.2 for Securities of any
Series, interest on the Securities of each Series shall be computed on the basis
of a 360-day year of twelve 30-day months.

    The
Company in issuing the Securities may use one or more “CUSIP” numbers, and, if
the Company does so, the Trustee shall use the CUSIP number(s) in notices of
redemption or exchange as a convenience to Holders, PROVIDED, that any such
notice may state that no representation is made as to the correctness or
accuracy of the CUSIP number(s) printed in the notice or on the Securities, and
that reliance may be placed only on the other identification numbers printed on
the Securities, and that any such redemption or exchange shall not be affected
by any defect in or omission of any such numbers.

              PROVISIONS
      FOR GLOBAL SECURITIES.

            


    

     

    (a) A
Board Resolution, a supplemental indenture hereto or an Officers’ Certificate
shall establish whether the Securities of a Series shall be issued in whole or
in part in the form of one or more Global Securities, and the Depository for
such Global Securities or Securities.

    (b) Notwithstanding
any provisions to the contrary contained in Section 2.7 and in addition
thereto, if, and only if the Depository (i) at any time is unwilling or
unable to continue as Depository for such Global Security or ceases to be a
clearing agency registered under the Exchange Act and (ii) a successor
Depository is not appointed by the Company within 90 days after the date
the Company is so informed in writing or becomes aware of the same, the Company
promptly will execute and deliver to the Trustee definitive Securities, and the
Trustee, upon receipt of a Company Request for the authentication and delivery
of such definitive Securities (which the Company will promptly execute and
deliver to the Trustee) and an Officers’ Certificate to the effect that such
Global Security shall be so exchangeable, will authenticate and deliver
definitive Securities, without charge, registered in such names and in such
authorized denominations as the Depository shall direct in writing (pursuant to
instructions from its direct and indirect participants or otherwise) in an
aggregate principal amount equal to the principal amount of the Global Security
with like tenor and terms. Upon the exchange of a Global Security for definitive
Securities, such Global Security shall be canceled by the Trustee. Unless and
until it is exchanged in whole or in part for definitive Securities, as provided
in this Section 2.15(b), a Global Security may not be transferred except as
a whole by the Depository with respect to such Global Security to a nominee of
such Depository, by a nominee of such Depository to such Depository or another
nominee of such Depository or by the Depository or any such nominee to a
successor Depository or a nominee of such a successor Depository.

     

    (c) Any
Global Security issued hereunder shall bear a legend in substantially the
following form:

     

    “This
Security is a Global Security within the meaning of the Indenture hereinafter
referred to, and is registered in the name of the Depository or a nominee of the
Depository. This Security is exchangeable for Securities registered in the name
of a Person other than the Depository or its nominee only in the limited
circumstances described in the Indenture, and may not be transferred except as a
whole by the Depository to a nominee of the Depository, by a nominee of the
Depository to the Depository or another nominee of the Depository or by the
Depository or any such nominee to a successor Depository or a nominee of such a
successor Depository.”

     

    (d) The
Depository, as a Holder, may appoint agents and otherwise authorize participants
to give or take any request, demand, authorization, direction, notice, consent,
waiver or other action which a Holder is entitled to give or take under the
Indenture.

     

    (e) Notwithstanding
the other provisions of this Indenture, unless otherwise specified as
contemplated by Section 2.2, payment of the principal of, and interest and
premium, if any, on, any Global Security shall be made to the Depository or its
nominee in its capacity as the Holder thereof.

     

    (f) Except
as provided in Section 2.15(e) above, the Company, the Trustee and any
Agent shall treat a Person as the Holder of such principal amount of outstanding
Securities of any Series represented by a Global Security as shall be specified
in a written statement of the Depository (which may be in the form of a
participants’ list for such Series) with respect to such Global Security, for
purposes of obtaining any consents, declarations, waivers or directions required
to be given by the Holders pursuant to this Indenture, PROVIDED, that until the
Trustee is so provided with a written statement, it may treat the Depository or
any other Person in whose name a Global Security is registered as the owner of
such Global Security for the purpose of receiving payment of the principal of,
and any premium and (subject to Section 2.13) any interest on, such Global
Security and for all other purposes whatsoever, and none of the Company, the
Trustee or any agent of the Company or the Trustee shall be affected by notice
to the contrary.

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 the principal of,

              NOTICES
      TO TRUSTEE.

            


    

     

    The
Company may, with respect to any Series of Securities, reserve the right to
redeem and pay the Series of Securities, or may covenant to redeem and pay the
Series of Securities or any part thereof, prior to the Stated Maturity thereof
at such time and on such terms as provided for in such Securities or the related
Board Resolution, supplemental indenture or Officers’ Certificate. If a Series
of Securities is redeemable and the Company elects to redeem all or part of such
Series of Securities, it shall notify the Trustee of the Redemption Date and the
principal amount of Securities to be redeemed at least 45 days (unless a
shorter notice shall be satisfactory to the Trustee) before the Redemption Date.
Any such notice may be canceled at any time prior to notice of such redemption
being mailed to any Holder, and shall thereby be void and of no
effect.

              SELECTION
      BY TRUSTEE OF SECURITIES TO BE
REDEEMED.

            


    

     

    Unless
otherwise indicated for a particular Series of Securities by a Board Resolution,
a supplemental indenture or an Officers’ Certificate, if fewer than all of the
Securities of a Series are to be redeemed, the Trustee shall select the
Securities of a Series to be redeemed pro rata, by lot or by any other method
that the Trustee considers fair and appropriate (unless the Company specifically
directs the Trustee otherwise) and, if such Securities are listed on any
securities exchange, by a method that complies with the requirements of such
exchange.

     

    The
Trustee shall make the selection from Securities of a Series outstanding and not
previously called for redemption, and shall promptly notify the Company in
writing of the Securities selected for redemption and, in the case of any
Security selected for partial redemption, the principal amount thereof to be
redeemed at least 35 but not more than 60 days before the Redemption Date.
Securities of a Series in denominations of $1,000 may be redeemed only in whole.
The Trustee may select for redemption portions of the principal of Securities of
a Series that have denominations larger than $1,000. Securities of a Series and
portions of them it selects shall be in amounts of $1,000 or, with respect to
Securities of any Series issuable in other denominations pursuant to
Section 2.2(10), the minimum principal denomination for each Series and
integral multiples thereof. Provisions of this Indenture that apply to
Securities called for redemption also apply to portions of Securities called for
redemption.

     

    
      	
              3.3

            	
              NOTICE
      OF REDEMPTION.

            


    

     

    Unless
otherwise indicated for a particular Series by Board Resolution, a supplemental
indenture hereto or an Officers’ Certificate, at least 30 days, and no more
than 60 days, before a Redemption Date, the Company shall mail, or cause to
be mailed, a notice of redemption by first-class mail to each Holder of
Securities to be redeemed at his or her last address as the same appears on the
registry books maintained by the Registrar. The notice shall identify the
Securities to be redeemed and shall state:

     

    (1) the
Redemption Date;

     

    (2) the
redemption price, and that such redemption price shall become due and payable on
the Redemption Date;

     

    (3) if
any Security of a Series is being redeemed in part, the portion of the principal
amount of such Security of a Series to be redeemed and that, after the
Redemption Date and upon surrender of such Security of a Series, a new Security
or Securities in principal amount equal to the unredeemed portion will be
issued;

     

    (4) the
name and address of the Paying Agent;

     

    (5) that
Securities of a Series called for redemption must be surrendered to the Paying
Agent to collect the redemption price, and the place or places where each such
Security is to be surrendered for such payment;

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

     

    (7) if
fewer than all of the Securities of a Series are to be redeemed, the
identification of the particular Securities of a Series (or portion thereof) to
be redeemed, as well as the aggregate principal amount of Securities of a Series
to be redeemed and the aggregate principal amount of Securities of a Series to
be outstanding after such partial redemption.

     

    (8) the
CUSIP number, if any, printed on the Securities being redeemed; and

     

    (9) that
no representation is made as to the correctness or accuracy of the CUSIP number,
if any, listed in such notice or printed on the Securities.

     

    At the
Company’s request, the Trustee shall give the notice of redemption in the
Company’s name and at the Company’s sole expense.

              EFFECT
      OF NOTICE OF REDEMPTION.

            


    

     

    Once the
notice of redemption described in Section 3.3 is mailed, Securities of a
Series called for redemption become due and payable on the Redemption Date and
at the redemption price, plus interest, if any, accrued to the Redemption Date.
Upon surrender to the Trustee or Paying Agent, such Securities of a Series shall
be paid at the redemption price, plus accrued interest, if any, to the
Redemption Date; PROVIDED, that if the Redemption Date is after a regular
interest payment record date and on or prior to the next Interest Payment Date,
the accrued interest shall be payable to the Holder of the redeemed Securities
registered on the relevant record date, as specified by the Company in the
notice to the Trustee pursuant to Section 3.1.

              DEPOSIT

    On or
prior to the Redemption Date (but no later than 11:00 A.M. Eastern Time on
such date), the Company shall deposit with the Paying Agent money sufficient to
pay the redemption price of and accrued interest, if any, on all Securities to
be redeemed on that date other than Securities or portions thereof called for
redemption on that date which have been delivered by the Company to the Trustee
for cancellation.

     

    On and
after any Redemption Date, if money sufficient to pay the redemption price of,
and accrued interest on, Securities called for redemption shall have been made
available in accordance with the preceding paragraph and the Company and the
Paying Agent are not prohibited from paying such moneys to Holders, the
Securities called for redemption will cease to accrue interest and the only
right of the Holders of such Securities will be to receive payment of the
redemption price of and, subject to the proviso in Section 3.4, accrued and
unpaid interest on such Securities to the Redemption Date. If any Security
called for redemption shall not be so paid, interest will be paid, from the
Redemption Date until such redemption payment is made, on the unpaid principal
of the Security and any interest or premium, if any, not paid on such unpaid
principal, in each case, at the rate and in the manner provided in the
Securities.

execute, and the Trustee shall authenticate, for a Holder a new Security of the
same Series equal in principal amount to the unredeemed portion of the Security
surrendered.

order or decree remains unstayed and in effect for 90 consecutive days;
or

     

    (6) any
other Event of Default provided with respect to Securities of that Series, which
is specified in a Board Resolution, a supplemental indenture hereto or an
Officers’ Certificate, in accordance with Section 2.2(19).

     

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

     

    The
Trustee may withhold notice of any Default (except in the payment of the
principal of, or interest or premium, if any, on, the Securities) to the Holders
of the Securities of any Series in accordance with Section 7.5. When a Default
is cured, it ceases to exist.

    If an
Event of Default with respect to Securities of any Series at the time
outstanding (other than an Event of Default arising under Section 6.1(4) or (5))
occurs and is continuing, the Trustee by written notice to the Company, or the
Holders of not less than 25% in aggregate principal amount of the Securities of
that Series then outstanding by written notice to the Company and the Trustee,
may declare that the entire principal amount of all the Securities of that
Series then outstanding plus accrued and unpaid interest to the date of
acceleration are immediately due and payable, in which case such amounts shall
become immediately due and payable; PROVIDED, HOWEVER, that after such
acceleration but before a judgment or decree based on such acceleration is
obtained by the Trustee, the Holders of a majority in aggregate principal amount
of the outstanding Securities of that Series may rescind and annul such
acceleration and its consequences if (i) all existing Events of Default, other
than the nonpayment of accelerated principal, interest or premium, if any, that
has become due solely because of the acceleration, have been cured or waived,
(ii) to the extent the payment of such interest is lawful, interest on overdue
installments of interest and overdue principal, which has become due otherwise
than by such declaration of acceleration, has been paid and (iii) the rescission
would not conflict with any judgment or decree. No such rescission shall affect
any subsequent Default or impair any right consequent thereto. In case an Event
of Default specified in Section 6.1(4) or (5) with respect to the Company
occurs, such principal, premium, if any, and interest amount with respect to all
of the Securities of that Series shall be due and payable immediately without
any declaration or other act on the part of the Trustee or the Holders of the
Securities of that Series.

              REMEDIES.

            


    

     

    If an
Event of Default with respect to Securities of any Series at the time
outstanding occurs and is continuing, the Trustee may pursue any available
remedy by proceeding at law or in equity to collect the payment of the principal
of, or interest and premium, if any, on, the Securities of that Series, or to
enforce the performance of any provision of the Securities of that Series or
this Indenture.

     

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

              WAIVER
      OF PAST DEFAULTS AND EVENTS OF
DEFAULT.

            


    

     

    Subject
to Sections 6.2, 6.7 and 8.2, the Holders of a majority in principal amount of
the Securities of any Series then outstanding have the right to waive any
existing Default or Event of Default with respect to such Series or compliance
with any provision of this Indenture (with respect to such Series) or the
Securities of such Series. Upon any such waiver, such Default with respect to
such Series shall cease to exist, and any Event of Default with respect to such
Series 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 Event of Default or impair any right consequent thereto. This Section
6.4 shall be in lieu of TIA Section 316(a)(1)(B), and TIA Section 316(a)(1)(B)
is hereby expressly excluded from this Indenture and Section as permitted by the
TIA.

    Subject
to Sections 6.2, 6.7 and 8.2, the Holders of a majority in principal amount of
the Securities of any Series then outstanding may direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee by this Indenture with
respect to such Series. The Trustee, however, may refuse to follow any direction
that conflicts with law or this Indenture, or that the Trustee determines may be
unduly prejudicial to the rights of another Securityholder, or that may involve
the Trustee in personal liability; PROVIDED, that the Trustee may take any other
action deemed proper by the Trustee which is not inconsistent with such
direction. This Section 6.5 shall be in lieu of TIA Section 316(a)(1)(A), and
TIA Section 316(a)(1)(A) is hereby expressly excluded from this Indenture and
Section as permitted by the TIA.

    Subject
to Section 6.7, a Securityholder may not institute any proceeding or pursue any
remedy with respect to this Indenture or the Securities of a Series
unless:

     

    (1) the
Holder gives to the Trustee written notice of a continuing Event of Default with
respect to the Securities of that Series;

     

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

     

    (3) such
Holder or Holders offer to the Trustee indemnity reasonably satisfactory to the
Trustee against any loss, liability or expense to be incurred in compliance with
such request;

     

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

     

    (5) no
direction inconsistent with such written request has been given to the Trustee
during such 60-day period by the Holders of a majority in aggregate principal
amount of the Securities of such Series then outstanding.

     

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

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

      SUIT BY TRUSTEE.

            


    

     

    If an
Event of Default in payment of principal, interest or premium, if any, specified
in Section 6.1(1) or (2) with respect to Securities of any Series at the time
outstanding occurs and is continuing, the Trustee may recover judgment in its
own name and as trustee of an express trust against the Company (or any other
obligor on the Securities of that Series) for the whole amount of unpaid
principal and premium, if any, and accrued interest remaining unpaid, together
with interest on overdue principal and premium, if any, and, to the extent that
payment of such interest is lawful, interest on overdue installments of
interest, in each case at the rate then borne by the Securities of that Series,
and such further amounts 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, as set forth in Section
7.7.

              TRUSTEE
      MAY FILE PROOFS OF CLAIM.

            


    

     

    The
Trustee may file such proofs of claim and other papers or documents, and take
other actions (including sitting on a committee of creditors), as may be
necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel) and the Securityholders allowed in any
judicial proceedings relative to the Company (or any other obligor on the
Securities), any of their respective creditors or any of their respective
property, and the Trustee shall be entitled and empowered to collect and receive
any monies or other property payable or deliverable on any such claims, and to
distribute the same after deduction of its charges and expenses to the extent
that any such charges and expenses are not paid out of the estate in any such
proceedings, and any custodian in any such judicial proceeding is hereby
authorized by each Securityholder 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 Securityholders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel, and any other amounts due the Trustee under Section
7.7.

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

              PRIORITIES.

            


    

     

    If the
Trustee collects any money pursuant to this Article 6, it shall pay out the
money in the following order:

     

    FIRST: to
the Trustee for amounts due under Section 7.7;

     

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

     

    THIRD: to
the Company.

     

    The
Trustee may fix a record date and payment date for any payment to
Securityholders pursuant to this Section 6.10. At least 15 days before such
record date, the Trustee shall mail to each Securityholder a notice that states
the record date, the payment date and amount to be paid.

    In any
suit for the enforcement of any right or remedy under this Indenture, or in any
suit against the Trustee for any action taken or omitted by it as Trustee, a
court in its discretion may require the filing by any party litigant in the suit
of an undertaking to pay the costs of the suit, and the court in its discretion
may assess reasonable costs, including reasonable attorneys’ fees, against any
party litigant in the suit, having due regard to the merits and good faith of
the claims or defenses made by the party litigant. This Section 6.11 does not
apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7 or a
suit by Holders of more than 10% in principal amount of the Securities of a
Series then outstanding.

              DUTIES
      OF TRUSTEE.

            


    

     

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

     

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

     

    (1) The
Trustee need perform only those duties that are specifically set forth in this
Indenture, and no covenants or obligations shall be implied in this Indenture
against the Trustee.

     

    (2) In
the absence of bad faith on its part, the Trustee may conclusively rely, as to
the truth of the statements and the correctness of the opinions expressed
therein, upon certificates or opinions furnished to the Trustee and conforming
to the requirements of this Indenture, but, in the case of any such certificates
or opinions which by any provision hereof are specifically required to be
furnished to the Trustee, the Trustee shall be under a duty to examine the same
to determine whether or not they conform to the requirements of this
Indenture.

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

     

    (1) This
paragraph does not limit the effect of paragraph (b) of this Section
7.1.

     

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

     

    (3) The
Trustee shall not be liable with respect to any action it takes or omits to take
in good faith in accordance with a direction received by it pursuant to Sections
6.2 and 6.5.

     

    (d) 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 rights or powers if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity satisfactory to it against such
risk or liability is not reasonably assured to it.

     

    (e)
Whether or not therein expressly so provided, paragraphs (a), (b), (c) and (d)
of this Section 7.1 shall govern every provision of this Indenture that in any
way relates to the Trustee.

     

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

     

    (g) The
Paying Agent, the Registrar and any authenticating agent shall be entitled to
the protections, immunities and standard of care set forth in paragraphs (a),

Trustee.

              RIGHTS
      OF TRUSTEE.

            


    

     

    (a)
Subject to Section 7.1:

     

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

     

    (2)
Before the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel, or both, which shall conform to the
provisions of Section 10.5. The Trustee shall be protected and shall not be
liable for any action it takes or omits to take in good faith in reliance on
such certificate or opinion.

     

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

     

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

     

    (5) The
Trustee may consult with counsel reasonably acceptable to the Trustee, which may
be counsel to the Company, and the advice or opinion of such counsel as to
matters of law shall be full and complete authorization and protection from
liability in respect of any action taken, omitted or suffered by it hereunder in
good faith and in accordance with the advice or opinion of such
counsel.

     

    (6) The
Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request, order or direction of any of the
Holders pursuant to the provisions of this Indenture, unless such Holders shall
have offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which may be incurred therein or thereby.

    (7) The
Trustee shall not be deemed to have knowledge of any fact or matter (including,
without limitation, a Default or Event of Default) unless such fact or matter is
known to a Responsible Officer of the Trustee.

     

    (8)
Unless otherwise expressly provided herein or in the Securities of a Series or
the related Board Resolution, supplemental indenture or Officers’ Certificate,
the Trustee shall not have any responsibility with respect to reports, notices,
certificates or other documents filed with it hereunder, except to make them
available for inspection, at reasonable times, by Securityholders, it being
understood that delivery of such reports, information and documents to the
Trustee is for informational purposes only and the Trustee’s receipt of such
shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company’s
compliance with any of its covenants hereunder (except as set forth in Section
4.4).

              INDIVIDUAL
      RIGHTS OF TRUSTEE.

            


    

     

    The
Trustee in its individual or any other capacity may become the owner or pledgee
of Securities, and may make loans to, accept deposits from, perform services for
or otherwise deal with the Company, or any Affiliate thereof, with the same
rights it would have if it were not Trustee. Any Agent may do the same with like
rights. The Trustee, however, shall be subject to Sections 7.10 and
7.11.

     

    
      	
              7.4

            	
              TRUSTEE’S
      DISCLAIMER.

            


    

     

    The
Trustee makes no representation as to the validity or adequacy of this Indenture
or the Securities (except that the Trustee represents that it is duly authorized
to execute and deliver this Indenture and authenticate the Securities and
perform its obligations hereunder), and the Trustee shall not be accountable for
the Company’s use of the proceeds from the sale of Securities or any money paid
to the Company pursuant to the terms of this Indenture, and the Trustee shall
not be responsible for any statement in the Securities other than its
certificates of authentication.

     

    
      	
              7.5

            	
              NOTICE
      OF DEFAULT.

            


    

     

    If a
Default or an Event of Default occurs and is continuing with respect to the
Securities of any Series, and if it is known to the Trustee, the Trustee shall
mail to each Securityholder of the Securities of that Series notice of the
Default or the Event of Default, as the case may be, within 90 days after it
occurs or, if later, after a Responsible Officer of the Trustee has knowledge of
such Default or Event of Default (except if such Default or Event of Default has
been validly cured or waived before the giving of such notice). Except in the
case of a Default or an Event of Default in payment of the principal of, or
interest or premium, if any, on, any Security of any Series, the Trustee may
withhold the notice if and so long as the Board of Directors of the Trustee, the
executive committee or any trust committee of such board and/or its Responsible
Officers in good faith determine(s) that withholding the notice is in the
interests of the Securityholders of that Series.

     

    
      	
              7.6

            	
              REPORTS
      BY TRUSTEE TO HOLDERS.

            


    

     

    If and to
the extent required by the TIA, within 60 days after April 1 of each year,
commencing the April 1 following the date of this Indenture, the Trustee shall
mail to each Securityholder a brief report dated as of such April 1 that
complies with TIA Section 313(a). The Trustee also shall comply with TIA
Sections 313(b) and 313(c).

     

    A copy of
each report at the time of its mailing to Securityholders shall be filed with
the SEC and any stock exchange on which the Securities of that Series are
listed. The Company shall promptly notify the Trustee when the Securities of any
Series are listed on any stock exchange or any delisting thereof, and the
Trustee shall comply with TIA Section 313(d).

     

    
      	
              7.7

            	
              COMPENSATION
      AND INDEMNITY.

            


    

     

    The
Company shall pay to the Trustee from time to time reasonable compensation for
its services. The Trustee’s compensation shall not be limited by any provision
of law on compensation of a trustee of an express trust. The Company shall
reimburse the Trustee within 45 days after receipt of request for all reasonable
out-of-pocket disbursements and expenses incurred or made by it in connection
with its duties under this Indenture, including the reasonable compensation,
disbursements and expenses of the Trustee’s agents and counsel.

     

    
      
        
        

      

      
        22

        
          

        

      

      
        
        

      

    

     

    The
Company shall indemnify the Trustee for, and hold it harmless against, any and
all loss or liability incurred by it in connection with the acceptance or
performance of its duties under this Indenture including the reasonable 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. The
Trustee shall notify the Company promptly of any claim asserted against the
Trustee for which it may seek indemnity.

     

    The
failure by the Trustee to so notify the Company shall not however relieve the
Company of its obligations. Notwithstanding the foregoing, the Company need not
reimburse the Trustee for any expense or indemnify it against any loss or
liability incurred by the Trustee through its negligence or bad faith. To secure
the payment obligations of the Company in this Section 7.7, the Trustee shall
have a lien prior to the Securities of any Series on all money or property held
or collected by the Trustee except such money or property held in trust to pay
the principal of, interest and premium, if any, on particular Securities of that
Series.

     

    When the
Trustee incurs expenses or renders services after an Event of Default specified
in Section 6.1(4) or (5) occurs, the expenses and the compensation for the
services are intended to constitute expenses of administration under any
Bankruptcy Law.

     

    For
purposes of this Section 7.7, the term “Trustee” shall include any trustee

    The
Trustee may resign with respect to the Securities of one or more Series by so
notifying the Company in writing at least 90 days in advance of such
resignation.

     

    The
Holders of a majority in principal amount of the outstanding Securities of any
Series may remove the Trustee with respect to that Series by notifying the
removed Trustee in writing and may appoint a successor Trustee with respect to
that Series with the consent of the Company, which consent shall not be
unreasonably withheld. The Company may remove the Trustee with respect to that
Series at its election if:

     

    (1) the
Trustee fails to comply with, or ceases to be eligible under, Section
7.10;

     

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

     

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

     

    (4) the
Trustee otherwise becomes incapable of acting.

     

    (5) If
the Trustee resigns or is removed, or if a vacancy exists in the office of
Trustee, with respect to any Series of Securities for any reason, the Company
shall promptly appoint, by Board Resolution, a successor Trustee.

     

    If a
successor Trustee with respect to the Securities of one or more Series does not
take office within 60 days after the retiring Trustee resigns or is removed, the
retiring Trustee, the Company or the Holders of at least 10% in principal amount
of the outstanding Securities of the applicable Series may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

     

    If the
Trustee with respect to the Securities of one or more Series fails to comply
with Section 7.10, any Securityholder of the applicable Series may petition any
court of competent jurisdiction for the removal of the Trustee and the
appointment of a successor Trustee.

    A
successor Trustee shall deliver a written acceptance of its appointment to the
retiring Trustee and to the Company. Immediately following such delivery, (i)
the retiring Trustee with respect to one or more Series shall, subject to its
rights under Section 7.7, transfer all property held by it as Trustee with
respect to such Series to the successor Trustee, (ii) the resignation or removal
of the retiring Trustee shall become effective and (iii) the successor Trustee
with respect to such Series shall have all the rights, powers and duties of the
Trustee under this Indenture. A successor Trustee with respect to the Securities
of one or more Series shall mail notice of its succession to each Securityholder
of such Series.

    If the
Trustee, or any Agent, consolidates with, merges or converts into, or transfers
all or substantially all of its corporate trust assets to, another corporation,
subject to Section 7.10, the successor corporation without any further act shall
be the successor Trustee or Agent, as the case may be.

    This
Indenture shall always have a Trustee who satisfies the requirements of TIA
Sections 310(a)(1), (2) and (5) in every respect. The Trustee (or in the case of
a Trustee that is a Person included in a bank holding company system, the
related bank holding company) shall have a combined capital and surplus of at
least $100,000,000 as set forth in its most recent published annual report of
condition. The Trustee shall comply with TIA Section 310(b), including the
provision in Section 310(b)(1). In addition, if the Trustee is a Person included
in a bank holding company system, the Trustee, independently of such bank
holding company, shall meet the capital requirements of TIA Section 310(a)(2).
If at any time the Trustee shall cease to be eligible in accordance with the
provisions of this Section 7.10, it shall resign immediately in the manner and
with the effect specified in this Article 7.

    (1) that

or interest or premium, if any, on, the Securities (whether such sums have been
paid to it by the Company or by any obligor on the Securities) in trust for the
benefit of Holders of the Securities or the Trustee;

     

    (2) that
it will at any time during the continuance of any Event of Default, upon written
request from the Trustee, deliver to the Trustee all sums so held in trust by it
together with a full accounting thereof; and

     

    (3) that
it will give the Trustee written notice within three Business Days after any

    The
Company, when authorized by a Board Resolution, and the Trustee may amend or
supplement this Indenture or the Securities of one or more Series without notice
to or consent of any Securityholder:

    (2) to

Securities;

     

    (3) to
comply with any requirements of the SEC under the TIA;

     

    (4) to
cure any ambiguity, defect or inconsistency, or to make any other change herein
or in the Securities that does not materially and adversely affect the rights of
any Securityholder;

     

    (5) to
provide for the issuance of, and establish the form and terms and conditions of,
Securities of any Series as permitted by this Indenture; or

Trustee with respect to the Securities of one or more Series, and to add to or

Trustee.

     

    The
Trustee is hereby authorized to join with the Company in the execution of any
supplemental indenture authorized or permitted by the terms of this Indenture,
and to make any further appropriate agreements and stipulations which may be
therein contained, but the Trustee shall not be obligated to enter into any such
supplemental indenture which adversely affects its own rights, duties or
immunities under this Indenture.

     

    
      	
              8.2

            	
              WITH
      CONSENT OF HOLDERS.

            


    

     

    (a) The
Company, when authorized by a Board Resolution, and the Trustee may amend or
supplement this Indenture or the Securities of one or more Series with the
written consent of the Holders of not less than a majority in aggregate
principal amount of the outstanding Securities of such Series affected by such
amendment or supplement without notice to any Securityholder. The Holders of not
less than a majority in aggregate principal amount of the outstanding Securities
of each such Series affected by such amendment or supplement may waive
compliance by the Company in a particular instance with any provision of this
Indenture or the Securities of such Series without notice to any Securityholder.
Subject to Section 8.4, without the consent of each Securityholder affected,
however, an amendment, supplement or waiver may not:

     

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

     

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

     

    (3)
reduce the principal, or change the Stated Maturity, of any Security, or reduce
the amount of, or postpone the date fixed for, the payment of any sinking fund
or analogous obligation;

     

    (4) make
any Security payable in money other than that stated in the
Security;

     

    (5)
change the amount or time of any payment required by the Securities, or reduce
the premium payable upon any redemption of the Securities, or change the time
before which no such redemption may be made;

     

    (6) waive
a Default or Event of Default in the payment of the principal of, or interest or
premium, if any, on, any Security (except a rescission of acceleration of the
Securities of any Series by the Holders of at least a majority in principal
amount of the outstanding Securities of such Series and a waiver of the payment
default that resulted from such acceleration);

     

    (7) waive
a redemption payment with respect to any Security, or change any of the
provisions with respect to the redemption of any Securities;

     

    (8) make
any changes in Section 6.6 or this Section 8.2, except to increase any
percentage of Securities the Holders of which must consent to any matter;
or

     

    
      
        
        

      

      
        25

        
          

        

      

      
        
        

      

    

     

    (9) take
any other action otherwise prohibited by this Indenture to be taken without the
consent of each Holder affected thereby.

     

    (b) Upon
the request of the Company, accompanied by a Board Resolution authorizing the
execution of any such supplemental indenture, and upon the receipt by the
Trustee of evidence reasonably satisfactory to the Trustee of the consent of the
Securityholders as aforesaid and of the documents described in Section 8.6, the
Trustee shall join with the Company in the execution of such supplemental
indenture, unless such supplemental indenture affects the Trustee’s own rights,
duties or immunities under this Indenture, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such supplemental
indenture.

     

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

     

    After an
amendment or supplement under this Section becomes effective, the Company shall
mail to Securityholders a notice briefly describing the amendment or supplement.
Any failure of the Company to mail any such notice, or any defect therein, shall
not, however, in any way impair or affect the validity of any supplemental
indenture.

              COMPLIANCE
      WITH TRUST INDENTURE ACT.

            


    

     

    Every
amendment to, or supplement of, this Indenture or the Securities shall comply
with the TIA as then in effect.

              REVOCATION
      AND EFFECT OF CONSENTS.

            


    

     

    Until an
amendment, supplement, waiver or other action becomes effective, a consent to it
by a Holder of a Security is a continuing consent conclusive and binding upon
such Holder and every subsequent Holder of the same Security or portion thereof,
and of any Security issued upon the transfer thereof or in exchange therefor or
in place thereof, even if notation of the consent is not made on any such
Security. Any such Holder or subsequent Holder, however, may revoke the consent
as to his Security or portion of a Security, if the Trustee receives the notice
of revocation before the date the amendment, supplement, waiver or other action
becomes effective.

     

    The
Company may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders entitled to consent to any amendment, supplement or
waiver, which record date shall be at least 30 days prior to the first
solicitation of such consent. If a record date is fixed, then, notwithstanding
the preceding paragraph, those Persons who were Holders at such record date (or
their duly designated proxies), and only such Persons, shall be entitled to
consent to such amendment, supplement or waiver, or to revoke any consent
previously given, whether or not such Persons continue to be Holders after such
record date.

     

    After an
amendment, supplement, waiver or other action becomes effective, it shall bind
every Securityholder, unless it makes a change described in any of clauses (1)
through (9) of Section 8.2. In that case, the amendment, supplement, waiver or
other action shall bind each Holder of a Security who has consented to it and
every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder’s Security; PROVIDED, that any such
waiver shall not impair or affect the right of any Holder to receive payment of
the principal of, and interest and premium, if any, on, a Security, on or after
the respective due dates expressed in such Security, or to bring suit for the
enforcement of any such payment on or after such respective dates without the
consent of such Holder.

    If an
amendment, supplement or waiver changes the terms of a Security of any Series,
the Trustee may request the Holder of such Security to deliver it to the
Trustee. In such case, the Trustee shall place an appropriate notation on such
Security about the changed terms and return it to the Holder. Alternatively, the
Company, in exchange for such Security, may issue, and the Trustee shall
authenticate, a new security that reflects the changed terms. Failure to make
the appropriate notation or issue a new Security shall not affect the validity
and effect of such amendment, supplement or waiver.

    The
Trustee shall sign any amendment, supplement or waiver authorized pursuant to
this Article 8 if the amendment, supplement or waiver does not adversely affect
the rights, duties, liabilities or immunities of the Trustee. If it does, the
Trustee may, but need not, sign it. In signing or refusing to sign such
amendment, supplement or waiver the Trustee shall be entitled to receive and,
subject to Section 7.1, shall be fully protected in relying upon an Officers’
Certificate and an Opinion of Counsel stating that such amendment, supplement or
waiver is authorized or permitted by this Indenture. The Company may not sign an
amendment or supplement until the Board of Directors of the Company approves
it.

      OF INDENTURE.

            


    

     

    The
Company may terminate its obligations under the Securities of any Series and
this Indenture with respect to such Series, except the obligations referred to
in the last paragraph of this Section 9.1, if there shall have been canceled by
the Trustee, or delivered to the Trustee for cancellation, all Securities of
such Series theretofore authenticated and delivered (other than any Securities
of such Series that are asserted to have been destroyed, lost or stolen and that
shall have been replaced as provided in Section 2.8) and the Company has paid
all sums payable by it hereunder or deposited all required sums with the
Trustee.

     

    After
such delivery the Trustee upon request shall acknowledge in a writing prepared
by or on behalf of the Company the discharge of the Company’s obligations under
the Securities of such Series and this Indenture, except for those surviving
obligations specified below.

     

    Notwithstanding
the satisfaction and discharge of this Indenture, the obligations of the Company
in Sections 7.7, 9.5 and 9.6 shall survive.

    The
Company may at its option, by Board Resolution, be discharged from its
obligations with respect to the Securities of any Series on the date upon which
the conditions set forth in Section 9.4 below are satisfied (hereinafter, “Legal
Defeasance”). For this purpose, such Legal Defeasance means that the Company
shall be deemed to have paid and discharged the entire indebtedness represented
by the Securities of such Series 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, subject to
Section 9.6, execute proper instruments acknowledging the same, as are delivered
to it by the Company), except for the following, which shall survive until
otherwise terminated or discharged hereunder: (A) the rights of Holders of
outstanding Securities of such Series to receive solely from the trust funds
described in Section 9.4 and as more fully set forth in such section, payments
in respect of the principal of, and interest and premium, if any, on, the
Securities of such Series when such payments are due, (B) the Company’s
obligations with respect to the Securities of such Series under Sections 2.4,
2.5, 2.6, 2.7, 2.8 and 2.9, (C) the rights, powers, trusts, duties and
immunities of the Trustee hereunder (including claims of, or payments to, the
Trustee under or pursuant to Section 7.7) and (D) this Article 9. Subject to
compliance with this Article 9, the Company may exercise its option under this
Section 9.2 with respect to the Securities of any Series notwithstanding the
prior exercise of its option under Section 9.3 below with respect to the
Securities of such Series.

    At the
option of the Company, pursuant to a Board Resolution, the Company shall be
released from its obligations with respect to the outstanding Securities of any
Series under Sections 4.2 through 4.5, inclusive, and Section 5.1, with respect
to the outstanding Securities of such Series, on and after the date the
conditions set forth in Section 9.4 are satisfied (hereinafter, “Covenant
Defeasance”). For this purpose, such Covenant Defeasance means that 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 or portion
thereof, whether directly or indirectly by reason of any reference elsewhere
herein to any such specified Section or portion thereof or by reason of any
reference in any such specified section or portion thereof to any other
provision herein or in any other document, but the remainder of this Indenture
and the Securities of any Series shall be unaffected thereby.

pledged as security for, and dedicated solely to, the benefit of the Holders of
the Securities, (A) money in an amount, or (B) U.S. Government Obligations or
Foreign Government Obligations which through the scheduled payment of principal

later than the due date of any payment, money in an amount, or (C) a combination
thereof, 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 other qualifying trustee) to pay and discharge, the principal
of, and accrued interest and premium, if any, on, the outstanding Securities of
such Series at the Stated Maturity of such principal, interest or premium, if
any, or on dates for payment and redemption of such principal, interest and

identified in paragraph (8) below (it being understood that this condition shall
not be deemed satisfied until the expiration of such period);

    (5) the
Company shall have delivered to the Trustee an Opinion of Counsel stating that,
as a result of such Legal Defeasance or Covenant Defeasance, neither the trust

    (6) in
the case of an election under Section 9.2, the Company shall have delivered to

not recognize income, gain or loss for Federal income tax purposes solely as a
result of such Legal Defeasance and will be subject to Federal income tax on the
same amounts, in the same manner, including as a result of prepayment, and at
the same times as would have been the case if such Legal Defeasance had not
occurred;

     

    (7) in

Covenant Defeasance under Section 9.3 (as the case may be) have been complied
with;

Company shall have paid, or duly provided for payment under terms mutually

      MONEY AND U.S. AND FOREIGN GOVERNMENT OBLIGATIONS TO BE HELD IN TRUST;
      OTHER MISCELLANEOUS PROVISIONS.

            


    

     

    All
money, U.S. Government Obligations and Foreign Government Obligations (including
the proceeds thereof) deposited with the Trustee pursuant to Section 9.4 in
respect of the outstanding 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 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, accrued interest and premium, if
any, but such money need not be segregated from other funds except to the extent
required by law.

     

    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 and Foreign
Government Obligations deposited pursuant to Section 9.4 or the principal,
interest and premium, if any, received in respect thereof other than any such
tax, fee or other charge which by law is for the account of the Holders of the
outstanding Securities.

     

    Anything
in this Article 9 to the contrary notwithstanding, but subject to payment of any
of its outstanding fees and expenses, 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 the Trustee as provided in
Section 9.4 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 an equivalent Legal Defeasance or Covenant
Defeasance.

              REINSTATEMENT.

            


    

     

    If the
Trustee or Paying Agent is unable to apply any money, U.S. Government
Obligations or Foreign Government Obligations in accordance with Section 9.1,
9.2, 9.3 or 9.4 by reason of any legal proceeding or by reason of any order or
judgment of any court or governmental authority enjoining, restraining or
otherwise prohibiting such application, the Company’s obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had occurred pursuant to this Article 9 until such time as the Trustee
or Paying Agent is permitted to apply all such money, U.S. Government
Obligations or Foreign Government Obligations, as the case may be, in accordance
with Section 9.1, 9.2, 9.3 or 9.4; PROVIDED, HOWEVER, that if the Company has
made any payment of principal of, or accrued interest or premium, if any, on,
any Securities because of the reinstatement of its obligations, the Company
shall be subrogated to the rights of the Holders of such Securities to receive
such payment from the money, U.S. Government Obligations or Foreign Government
Obligations held by the Trustee or Paying Agent.

    In
connection with the satisfaction and discharge of this Indenture, all moneys
then held by any Paying Agent under the provisions of this Indenture shall, upon
demand of the Company, be paid to the Trustee, or, if sufficient moneys have
been deposited pursuant to Section 9.1, to the Company, and thereupon such
Paying Agent shall be released from all further liability with respect to such
moneys.

      HELD BY TRUSTEE.

            


    

     

    Any
moneys deposited with the Trustee or any Paying Agent or then held by the
Company in trust for the payment of the principal of, or interest or premium, if
any, on, any Security that are not applied but remain unclaimed by the Holder of
such Security for two years after the date upon which the principal of, or
interest or premium, if any, on, such Security shall have respectively become
due and payable shall be repaid to the Company upon Company Request, or if such
moneys are then held by the Company in trust, such moneys shall be released from
such trust; and the Holder of such Security entitled to receive such payment
shall thereafter, as an unsecured general creditor, look only to the Company for
the payment thereof, and all liability of the Trustee or such Paying Agent with
respect to such trust money shall thereupon cease; PROVIDED, HOWEVER, that the
Trustee or any such Paying Agent, before being required to make any such
repayment, may, at the expense of the Company, either mail to each
Securityholder affected, at the address shown in the register of the Securities
maintained by the Registrar, or cause to be published once a week for two
successive weeks, in a newspaper published in the English language, customarily
published each Business Day and of general circulation in the City of New York,
New York, a 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
mailing or publication, any unclaimed balance of such moneys then remaining will
be repaid to the Company. After payment to the Company or the release of any
money held in trust by the Company, Securityholders entitled to the money must
look only to the Company for payment as general creditors, unless applicable
abandoned property law designates another Person.

    A
“Business Day” is a day that is not a Legal Holiday. A “Legal Holiday” is a
Saturday, a Sunday, a federally-recognized holiday or a day on which banking
institutions are not authorized or required by law, regulation or executive
order to be open in the State of New York.

     

    If a
payment date is a Legal Holiday at a Place of Payment, payment may be made at
that place on the next succeeding day that is not a Legal Holiday, and no
interest shall accrue for the intervening period. “Place of Payment” means the
place or places where the principal of, and interest and premium, if any, on,
the Securities of a Series are payable as specified as contemplated by Section
2.2. If the regular record date is a Legal Holiday, the record date shall not be
affected.

    A
director, officer, employee, stockholder or incorporator, as such, of the
Company shall not have any liability for any obligations of the Company under
the Securities or the Indenture. Each Securityholder by accepting a Security
waives and releases all such liability. Such waiver and release are part of the
consideration for the issuance of the Securities.

    Each
provision of this Indenture shall be considered separable, and if for any reason
any provision which is not essential to the effectuation of the basic purpose of
this Indenture or the Securities shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby, and a Holder shall have no claim
therefor against any party hereto.

    Unless
otherwise specified in a Board Resolution, a supplemental indenture hereto or an
Officers’ Certificate delivered pursuant to Section 2.2 with respect to a
particular Series of Securities, whenever for purposes of this Indenture any
action may be taken by the Holders of a specified percentage in aggregate
principal amount of Securities of all Series or all Series affected by a
particular action at the time outstanding and, at such time, there are
outstanding Securities of any Series which are denominated in a coin or currency
other than Dollars (including Euros), then the principal amount of Securities of
such Series which shall be deemed to be outstanding for the purpose of taking
such action shall be that amount of Dollars that could be obtained for such
amount at the Market Exchange Rate at such time. For purposes of this Section
10.15, “Market Exchange Rate” shall mean the noon Dollar buying rate in New York
City for cable transfers of that currency as published by the Federal Reserve
Bank of New York; PROVIDED, HOWEVER, in the case of Euros, Market Exchange Rate
shall mean the rate of exchange determined by the Commission of the European
Union (or any successor thereto) as published in the Official Journal of the
European Union (such publication or any successor publication, the “Journal”).
If such Market Exchange Rate is not available for any reason with respect to
such currency, the Trustee shall use, in its sole discretion and without
liability on its part, such quotation of the Federal Reserve Bank of New York
or, in the case of Euros, the rate of exchange as published in the Journal, as
of the most recent available date, or quotations or, in the case of Euros, rates
of exchange from one or more major banks in New York City or in the country of
issue of the currency in question or, in the case of Euros, in Luxembourg or
such other quotations or, in the case of Euros, rates of exchange as the
Trustee, upon consultation with the Company, shall deem appropriate. The
provisions of this paragraph shall apply in determining the equivalent principal
amount in respect of Securities of a Series denominated in currency other than
Dollars in connection with any action taken by Holders of Securities pursuant to
the terms of this Indenture.

     

    All
decisions and determinations of the Trustee regarding the Market Exchange Rate
or any alternative determination provided for in the preceding paragraph shall
be in the Trustee’s sole discretion, and shall, in the absence of manifest
error, be conclusive to the extent permitted by law for all purposes and
irrevocably binding upon the Company and all Holders.

              JUDGMENT
      CURRENCY.

            


    

     

    The
Company agrees, to the fullest extent that it may effectively do so under
applicable law, that (a) if for the purpose of obtaining judgment in any court
it is necessary to convert the sum due in respect of the principal of, or
interest or premium, if any, or other amount on, the Securities of any Series
(the “Required Currency”) into a currency in which a judgment will be rendered
(the “Judgment Currency”), the rate of exchange used shall be the rate at which,
in accordance with normal banking procedures, the Trustee could purchase in The
City of New York the Required Currency with the Judgment Currency on the day on
which final unappealable judgment is entered, unless such day is not a Business
Day, in which instance, the rate of exchange used shall be the rate at which, in
accordance with normal banking procedures, the Trustee could purchase in The
City of New York the Required Currency with the Judgment Currency on the
Business Day preceding the day on which final unappealable judgment is entered
and (b) its obligations under this Indenture to make payments in the Required
Currency (i) shall not be discharged or satisfied by any tender or any
recovery pursuant to any judgment (whether or not entered in accordance with
subsection (a)) in any currency other than the Required Currency, except to the
extent that such tender or recovery shall result in the actual receipt, by the
payee, of the full amount of the Required Currency expressed to be payable in
respect of such payments, (ii) shall be enforceable as an alternative or
additional cause of action for the purpose of recovering in the Required
Currency the amount, if any, by which such actual receipt shall fall short of
the full amount of the Required Currency so expressed to be payable and
(iii) shall not be affected by judgment being obtained for any other sum
due under this Indenture.

     

    IN
WITNESS WHEREOF, the parties hereto have caused this Indenture to be duly
executed, and their respective corporate seals to be hereunto affixed and
