    Section

    The

Securities of any series, as well as any premium thereon in case of redemption

    Any
interest on any Security that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date for Securities of the same series
(herein called “Defaulted Interest”) shall forthwith cease to be payable to the
registered holder on the relevant regular record date by virtue of having been
such holder; and such Defaulted Interest shall be paid by the Company, at its
election, as provided in clause (1) or clause (2) below:

     

    (1)           The
Company may make payment of any Defaulted Interest on Securities to the Persons
in whose names such Securities (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 such Security 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 not be more than 15 nor 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 mailed, first class postage prepaid,
to each Securityholder at his or her address as it appears in the Security
Register (as hereinafter defined), 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 mailed as aforesaid, such Defaulted
Interest shall be paid to the Persons in whose names such Securities (or their
respective Predecessor Securities) are registered on such special record
date.

     

    (2)           The
Company may make payment of any Defaulted Interest on any Securities 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.

     

    Unless
otherwise set forth in a Board Resolution or one or more indentures supplemental
hereto establishing the terms of any series of Securities pursuant to Section
2.01 hereof, the term “regular record date” as used in this Section with respect
to a series of Securities and any Interest Payment Date for such series shall
mean either the fifteenth day of the month immediately preceding the month in
which an Interest Payment Date established for such series pursuant to Section
2.01 hereof shall occur, if such Interest Payment Date is the first day of a
month, or the first day of the month in which an Interest Payment Date
established for such series pursuant to Section 2.01 hereof shall occur, if such
Interest Payment Date is the fifteenth day of a month, whether or not such date
is a Business Day.

     

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

    The
Securities shall be signed on behalf of the Company by one of its Officers.
Signatures may be in the form of a manual or facsimile signature.

     

    The
Company may use the facsimile signature of any Person who shall have been an
Officer, notwithstanding the fact that at the time the Securities shall be
authenticated and delivered or disposed of such Person shall have ceased to be
such an officer of the Company. The Securities may contain such notations,
legends or endorsements required by law, stock exchange rule or usage. Each
Security shall be dated the date of its authentication by the
Trustee.

     

    A
Security shall not be valid until authenticated manually by an authorized
signatory of the Trustee, or by an Authenticating Agent. Such signature shall be
conclusive evidence that the Security so authenticated has been duly
authenticated and delivered hereunder and that the holder is entitled to the
benefits of this Indenture. At any time and from time to time after the
execution and delivery of this Indenture, the Company may deliver Securities of
any series executed by the Company to the Trustee for authentication, together
with a written order of the Company for the authentication and delivery of such
Securities, signed by an Officer, and the Trustee in accordance with such
written order shall authenticate and deliver such Securities.

     

    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 7.01) shall be fully protected in
relying upon, an Opinion of Counsel stating that the form and terms thereof have
been established in conformity with the provisions of this
Indenture.

     

    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 that is not reasonably acceptable to the Trustee.

     

    Section
2.05    Registration Of Transfer And Exchange.

of any series may be exchanged upon presentation thereof at the office or agency
of the Company designated for such purpose, for other Securities of such series
of authorized denominations, and for a like aggregate principal amount, upon
payment of a sum sufficient to cover any tax or other governmental charge in
relation thereto, all as provided in this Section. In respect of any Securities
so surrendered for exchange, the Company shall execute, the Trustee shall
authenticate and such office or agency shall deliver in exchange therefor the
Security or Securities of the same series that the Securityholder making the
exchange shall be entitled to receive, bearing numbers not contemporaneously
outstanding.

     

    (b)           The
Company shall keep, or cause to be kept, at its office or agency designated for
such purpose a register or registers (herein referred to as the “Security
Register”) in which, subject to such reasonable regulations as it may
prescribe, the Company shall register the Securities and the transfers of
Securities as in this Article provided and which at all reasonable times shall
be open for inspection by the Trustee. The registrar for the purpose of
registering Securities and transfer of Securities as herein provided shall be
appointed as authorized by Board Resolution (the “Security
Registrar”).

    Upon
surrender for transfer of any Security at the office or agency of the Company
designated for such purpose, the Company shall execute, the Trustee shall
authenticate and such office or agency shall deliver in the name of the
transferee or transferees a new Security or Securities of the same series as the
Security presented for a like aggregate principal amount.

     

    All
Securities presented or surrendered for exchange or registration of transfer, as
provided in this Section, shall be accompanied (if so required by the Company or
the Security Registrar) by a written instrument or instruments of transfer, in
form satisfactory to the Company or the Security Registrar, duly executed by the
registered holder or by such holder’s duly authorized attorney in
writing.

     

    (c)           Except
as provided pursuant to Section 2.01 pursuant to a Board Resolution, and set
forth in an Officer’s Certificate, or established in one or more indentures
supplemental to this Indenture, no service charge shall be made for any exchange
or registration of transfer of Securities, or issue of new Securities in case of
partial redemption of any series, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge in relation thereto,
other than exchanges pursuant to Section 2.06, Section 3.03(b) and Section 9.04
not involving any transfer.

     

    (d)           The
Company shall not be required (i) to issue, exchange or register the transfer of
any Securities during a period beginning at the opening of business 15 days
before the day of the mailing of a notice of redemption of less than all the
Outstanding Securities of the same series and ending at the close of business on
the day of such mailing, nor (ii) to register the transfer of or exchange any
Securities of any series or portions thereof called for redemption, other than
the unredeemed portion of any such Securities being redeemed in part. The
provisions of this Section 2.05 are, with respect to any Global Security,
subject to Section 2.11 hereof.

     

    The
Trustee shall have no obligation or duty to monitor, determine or inquire as to
compliance with any restrictions on transfer imposed under this Indenture or
under applicable law with respect to any transfer of any interest in any
Security (including any transfers between or among depositary participants or
beneficial owners of interests in any Global Security) other than to require
delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by the terms
of, this Indenture, and to examine the same to determine substantial compliance
as to form with the express requirements hereof.

    Section
2.06    Temporary Securities.

     

    Pending
the preparation of definitive Securities of any series, the Company may execute,
and the Trustee shall authenticate and deliver, temporary Securities (printed,
lithographed or typewritten) of any authorized denomination. Such temporary
Securities shall be substantially in the form of the definitive Securities in
lieu of which they are issued, but with such omissions, insertions and
variations as may be appropriate for temporary Securities, all as may be
determined by the Company. Every temporary Security of any series shall be
executed by the Company and be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with like effect, as the
definitive Securities of such series. Without unnecessary delay, the Company
will execute and will furnish definitive Securities of such series and thereupon
any or all temporary Securities of such series may be surrendered in exchange
therefor (without charge to the holders), at the office or agency of the Company
designated for the purpose, and the Trustee shall authenticate and such office
or agency shall deliver in exchange for such temporary Securities an equal
aggregate principal amount of definitive Securities of such series, unless the
Company advises the Trustee to the effect that definitive Securities need not be
executed and furnished until further notice from the Company. Until so
exchanged, the temporary Securities of such series shall be entitled to the same
benefits under this Indenture as definitive Securities of such series
authenticated and delivered hereunder.

     

    Section
2.07    Mutilated, Destroyed, Lost Or Stolen
Securities.

     

    In case
any temporary or definitive Security shall become mutilated or be destroyed,
lost or stolen, the Company (subject to the next succeeding sentence) shall
execute, and upon the Company’s request the Trustee (subject as aforesaid) shall
authenticate and deliver, a new Security of the same series, bearing a number
not contemporaneously outstanding, in exchange and substitution for the
mutilated Security, or in lieu of and in substitution for the Security so
destroyed, lost or stolen. In every case the applicant for a substituted
Security shall furnish to the Company and the Trustee such security or indemnity
as may be required by them to save each of them harmless, and, in every case of
destruction, loss or theft, the applicant shall also furnish to the Company and
the Trustee evidence to their satisfaction of the destruction, loss or theft of
the applicant’s Security and of the ownership thereof. The Trustee may
authenticate any such substituted Security and deliver the same upon the written
request or authorization of any officer of the Company. Upon the issuance of any
substituted Security, 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.

     

    In case
any Security that has matured or is about to mature shall become mutilated or be
destroyed, lost or stolen, the Company may, instead of issuing a substitute
Security, pay or authorize the payment of the same (without surrender thereof
except in the case of a mutilated Security) if the applicant for such payment
shall furnish to the Company and the Trustee such security or indemnity as they
may require to save them harmless, and, in case of destruction, loss or theft,
evidence to the satisfaction of the Company and the Trustee of the destruction,
loss or theft of such Security and of the ownership thereof.

     

    Every
replacement Security issued pursuant to the provisions of this Section shall
constitute an additional contractual obligation of the Company whether or not
the mutilated, destroyed, lost or stolen Security shall be found at any time, or
be enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Securities of the
same series duly issued hereunder. All Securities shall be held and owned upon
the express condition that the foregoing provisions are exclusive with respect
to the replacement or payment of mutilated, destroyed, lost or stolen
Securities, and shall preclude (to the extent lawful) any and all other rights
or remedies, notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

    Section
2.08    Cancellation.

     

    All
Securities surrendered for the purpose of payment, redemption, exchange or
registration of transfer shall, if surrendered to the Company or any paying
agent, be delivered to the Trustee for cancellation, or, if surrendered to the
Trustee, shall be cancelled by it, and no Securities shall be issued in lieu
thereof except as expressly required or permitted by any of the provisions of
this Indenture. On request of the Company at the time of such surrender, the
Trustee shall deliver to the Company canceled Securities held by the Trustee. In
the absence of such request the Trustee may dispose of canceled Securities in
accordance with its standard procedures and deliver a certificate of disposition
to the Company. If the Company shall otherwise acquire any of the Securities,
however, such acquisition shall not operate as a redemption or satisfaction of
the indebtedness represented by such Securities unless and until the same are
delivered to the Trustee for cancellation.

     

    Section
2.09    Benefits Of Indenture.

     

    Nothing
in this Indenture or in the Securities, express or implied, shall give or be
construed to give to any Person, other than the parties hereto and the holders
of the Securities any legal or equitable right, remedy or claim under or in
respect of this Indenture, or under any covenant, condition or provision herein
contained; all such covenants, conditions and provisions being for the sole
benefit of the parties hereto and of the holders of the Securities.

     

    Section
2.10    Authenticating Agent.

     

    So long
as any of the Securities of any series remain Outstanding there may be an
Authenticating Agent for any or all such series of Securities which the Trustee
shall have the right to appoint. Said Authenticating Agent shall be authorized
to act on behalf of the Trustee to authenticate Securities of such series issued
upon exchange, transfer or partial redemption thereof, 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. All references in this Indenture to the authentication of Securities
by the Trustee shall be deemed to include authentication by an Authenticating
Agent for such series. Each Authenticating Agent shall be acceptable to the
Company and shall be a corporation that has a combined capital and surplus, as
most recently reported or determined by it, sufficient under the laws of any
jurisdiction under which it is organized or in which it is doing business to
conduct a trust business, and that is otherwise authorized under such laws to
conduct such business and is subject to supervision or examination by federal or
state authorities. If at any time any Authenticating Agent shall cease to be
eligible in accordance with these provisions, it shall resign
immediately.


    Any
Authenticating Agent may at any time resign by giving written notice of
resignation to the Trustee and to the Company. The Trustee may at any time (and
upon request by the Company shall) terminate the agency of any Authenticating
Agent by giving written notice of termination to such Authenticating Agent and
to the Company. Upon resignation, termination or cessation of eligibility of any
Authenticating Agent, the Trustee may appoint an eligible successor
Authenticating Agent acceptable to the Company. Any successor Authenticating
Agent, upon acceptance of its appointment hereunder, shall become vested with
all the rights, powers and duties of its predecessor hereunder as if originally
named as an Authenticating Agent pursuant hereto.

    Section
2.11    Global Securities.

     

    (a)           If
the Company shall establish pursuant to Section 2.01 that the Securities of a
particular series are to be issued as a Global Security, then the Company shall
execute and the Trustee shall, in accordance with Section 2.04, authenticate and
deliver, a Global Security that (i) shall represent, and shall be denominated in
an amount equal to the aggregate principal amount of, all of the Outstanding
Securities of such series, (ii) shall be registered in the name of the
Depositary or its nominee, (iii) shall be delivered by the Trustee to the
Depositary or pursuant to the Depositary’s instruction and (iv) shall bear a
legend substantially to the following effect: “Except as otherwise provided in
Section 2.11 of the Indenture, this Security may be transferred, in whole but
not in part, only to another nominee of the Depositary or to a successor
Depositary or to a nominee of such successor Depositary.”

     

    (b)           Notwithstanding
the provisions of Section 2.05, the Global Security of a series may be
transferred, in whole but not in part and in the manner provided in Section
2.05, only to another nominee of the Depositary for such series, or to a
successor Depositary for such series selected or approved by the Company or to a
nominee of such successor Depositary.

     

    (c)           If
at any time the Depositary for a series of the Securities notifies the Company
that it is unwilling or unable to continue as Depositary for such series or if
at any time the Depositary for such series shall no longer be registered or in
good standing under the Exchange Act, or other applicable statute or regulation,
and a successor Depositary for such series is not appointed by the Company
within 90 days after the Company receives such notice or becomes aware of such
condition, as the case may be, or if an Event of Default has occurred and is
continuing and the Company has received a request from the Depositary or from
the Trustee, this Section 2.11 shall no longer be applicable to the Securities
of such series and the Company will execute, and subject to Section 2.04, the
Trustee will authenticate and deliver the Securities of such series in
definitive registered form without coupons, in authorized denominations, and in
an aggregate principal amount equal to the principal amount of the Global
Security of such series in exchange for such Global Security. In addition, the
Company may at any time determine that the Securities of any series shall no
longer be represented by a Global Security and that the provisions of this
Section 2.11 shall no longer apply to the Securities of such series. In such
event the Company will execute and, subject to Section 2.04, the Trustee, upon
receipt of an Officer’s Certificate evidencing such determination by the
Company, will authenticate and deliver the Securities of such series in
definitive registered form without coupons, in authorized denominations, and in
an aggregate principal amount equal to the principal amount of the Global
Security of such series in exchange for such Global Security. Upon the exchange
of the Global Security for such Securities in definitive registered form without
coupons, in authorized denominations, the Global Security shall be canceled by
the Trustee. Such Securities in definitive registered form issued in exchange
for the Global Security pursuant to this Section 2.11(c) shall be registered in
such names and in such authorized denominations as the Depositary, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Securities to the
Depositary for delivery to the Persons in whose names such Securities are so
registered.

    REDEMPTION
OF SECURITIES AND SINKING FUND PROVISIONS

     

    Section 3.01   
Redemption.

     

    The
Company may redeem the Securities of any series issued hereunder on and after
the dates and in accordance with the terms established for such series pursuant
to Section 2.01 hereof.

     

    Section
3.02    Notice Of Redemption.

     

    (a)           In
case the Company shall desire to exercise such right to redeem all or, as the
case may be, a portion of the Securities of any series in accordance with any
right the Company reserved for itself to do so pursuant to Section 2.01 hereof,
the Company shall, or shall cause the Trustee to, give notice of such redemption
to holders of the Securities of such series to be redeemed by mailing, first
class postage prepaid, a notice of such redemption not less than 30 days and not
more than 90 days before the date fixed for redemption of that series to such
holders at their last addresses as they shall appear upon the Security Register,
unless a shorter period is specified in the Securities to be redeemed. Any
notice that is mailed in the manner herein provided shall be conclusively
presumed to have been duly given, whether or not the registered holder receives
the notice. In any case, failure duly to give such notice to the holder of any
Security of any series designated for redemption in whole or in part, or any
defect in the notice, shall not affect the validity of the proceedings for the
redemption of any other Securities of such series or any other series. 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 Officer’s Certificate
evidencing compliance with any such restriction.

     

    Each such
notice of redemption shall specify the date fixed for redemption and the
redemption price at which Securities of that series are to be redeemed, and
shall state that payment of the redemption price of such Securities to be
redeemed will be made at the office or agency of the Company upon presentation
and surrender of such Securities, that interest accrued to the date fixed for
redemption will be paid as specified in said notice, that from and after said
date interest will cease to accrue and that the redemption is from a sinking
fund, if such is the case. If less than all the Securities of a series are to be
redeemed, the notice to the holders of Securities of that series to be redeemed
in part shall specify the particular Securities to be so redeemed.

     

    In case
any Security is to be redeemed in part only, the notice that relates to such
Security shall state the portion of the principal amount thereof to be redeemed,
and shall state that on and after the redemption date, upon surrender of such
Security, a new Security or Securities of such series in principal amount equal
to the unredeemed portion thereof will be issued.


    
      
         


      

      
        15

        
          

        

      

      
         


      

    

     

    (b)           If
less than all the Securities of a series are to be redeemed, the Company shall
give the Trustee at least 45 days’ notice (unless a shorter notice shall be
satisfactory to the Trustee) in advance of the date fixed for redemption as to
the aggregate principal amount of Securities of the series to be redeemed, and
thereupon the Trustee shall select, by lot or in such other manner as it shall
deem appropriate and fair in its discretion and that may provide for the
selection of a portion or portions (equal to one thousand U.S. dollars ($1,000)
or any integral multiple thereof) of the principal amount of such Securities of
a denomination larger than $1,000, the Securities to be redeemed and shall
thereafter promptly notify the Company in writing of the numbers of the
Securities to be redeemed, in whole or in part. The Company may, if and whenever
it shall so elect, by delivery of instructions signed on its behalf by an
Officer, instruct the Trustee or any paying agent to call all or any part of the
Securities of a particular series for redemption and to give notice of
redemption in the manner set forth in this Section, such notice to be in the
name of the Company or its own name as the Trustee or such paying agent may deem
advisable. In any case in which notice of redemption is to be given by the
Trustee or any such paying agent, the Company shall deliver or cause to be
delivered to, or permit to remain with, the Trustee or such paying agent, as the
case may be, such Security Register, transfer books or other records, or
suitable copies or extracts therefrom, sufficient to enable the Trustee or such
paying agent to give any notice by mail that may be required under the
provisions of this Section.

     

    Section
3.03    Payment Upon Redemption.

     

    (a)           If
the giving of notice of redemption shall have been completed as above provided,
the Securities or portions of Securities of the series to be redeemed specified
in such notice shall become due and payable on the date and at the place stated
in such notice at the applicable redemption price, together with interest
accrued to the date fixed for redemption and interest on such Securities or
portions of Securities shall cease to accrue on and after the date fixed for
redemption, unless the Company shall default in the payment of such redemption
price and accrued interest with respect to any such Security or portion thereof.
On presentation and surrender of such Securities on or after the date fixed for
redemption at the place of payment specified in the notice, said Securities
shall be paid and redeemed at the applicable redemption price for such series,
together with interest accrued thereon to the date fixed for redemption (but if
the date fixed for redemption is an interest payment date, the interest
installment payable on such date shall be payable to the registered holder at
the close of business on the applicable record date pursuant to Section
2.03).

     

    (b)           Upon
presentation of any Security of such series that is to be redeemed in part only,
the Company shall execute and the Trustee shall authenticate and the office or
agency where the Security is presented shall deliver to the holder thereof, at
the expense of the Company, a new Security of the same series of authorized
denominations in principal amount equal to the unredeemed portion of the
Security so presented.

     

    Section 3.04   
Sinking
Fund.

     

    The
provisions of Sections 3.04, 3.05 and 3.06 shall be applicable to any sinking
fund for the retirement of Securities of a series, except as otherwise specified
as contemplated by Section 2.01 for Securities of such series.

    The
minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a “mandatory sinking fund
payment,” and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an “optional sinking
fund payment”. If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as provided
in Section 3.05. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such
series.

     

    Section
3.05    Satisfaction Of Sinking Fund Payments
With Securities.

     

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

     

    Section
3.06    Redemption Of Securities For Sinking
Fund.

     

    Not less
than 45 days prior to each sinking fund payment date for any series of
Securities (unless a shorter period shall be satisfactory to the Trustee), the
Company will deliver to the Trustee an Officer’s Certificate specifying the
amount of the next ensuing sinking fund payment for that series pursuant to the
terms of the series, the portion thereof, if any, that is to be satisfied by
delivering and crediting Securities of that series pursuant to Section 3.05 and
the basis for such credit and will, together with such Officer’s Certificate,
deliver to the Trustee any Securities to be so delivered.  Not less
than 30 days before each such sinking fund payment date the Trustee shall select
the Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 3.02 and cause notice of the redemption thereof to be given
in the name of and at the expense of the Company in the manner provided in
Section 3.02. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Section
3.03.

    The
Company will duly and punctually pay or cause to be paid the principal of (and
premium, if any) and interest on the Securities of that series at the time and
place and in the manner provided herein and established with respect to such
Securities. Payments of principal on the Securities may be made at the time
provided herein and established with respect to such Securities by U.S. dollar
check drawn on and mailed to the address of the Securityholder entitled thereto

payment date. Payments of interest on the Securities may be made at the time
provided herein and established with respect to such Securities by U.S. dollar
check mailed to the address of the Securityholder entitled thereto as such
address shall appear in the Security Register, or U.S. dollar wire transfer to,
a U.S. dollar account if such Securityholder shall have furnished wire

    Section
4.02    Maintenance Of Office Or
Agency.

     

    So long
as any series of the Securities remain Outstanding, the Company agrees to
maintain an office or agency with respect to each such series and at such other
location or locations as may be designated as provided in this Section 4.02,
where (i) Securities of that series may be presented for payment, (ii)
Securities of that series may be presented as herein above authorized for
registration of transfer and exchange, and (iii) notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture may
be given or served, such designation to continue with respect to such office or
agency until the Company shall, by written notice signed by any officer
authorized to sign an Officer’s Certificate and delivered to the Trustee,
designate some other office or agency for such purposes or any of
them.  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, 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, notices and
demands.  The Company initially appoints the Corporate Trust Office of
the Trustee as its paying agent with respect to the Securities.

     

    Section
4.03    Paying Agents.

     

    (a)           If
the Company shall appoint one or more paying agents for all or any series of the
Securities, other than the Trustee, the Company will cause each such paying
agent to execute and deliver to the Trustee an instrument in which such agent
shall agree with the Trustee, subject to the provisions of this
Section:

     

    (1)           that
it will hold all sums held by it as such agent for the payment of the principal
of (and premium, if any) or interest on the Securities of that series (whether
such sums have been paid to it by the Company or by any other obligor of such
Securities) in trust for the benefit of the Persons entitled
thereto;

     

    (2)           that
it will give the Trustee notice of any failure by the Company (or by any other
obligor of such Securities) to make any payment of the principal of (and
premium, if any) or interest on the Securities of that series when the same
shall be due and payable;

     

    (3)           that
it will, at any time during the continuance of any failure referred to in the
preceding paragraph (a)(2) above, upon the written request of the Trustee,
forthwith pay to the Trustee all sums so held in trust by such paying agent;
and


    
      
         


      

      
        18

        
          

        

      

      
         


      

    


    (4)           that
it will perform all other duties of paying agent as set forth in this
Indenture.

     

    (b)           If
the Company shall act as its own paying agent with respect to any series of the
Securities, it will on or before each due date of the principal of (and premium,
if any) or interest on Securities of that series, set aside, segregate and hold
in trust for the benefit of the Persons entitled thereto a sum sufficient to pay
such principal (and premium, if any) or interest so becoming due on Securities
of that series until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of such
action, or any failure (by it or any other obligor on such Securities) to take
such action. Whenever the Company shall have one or more paying agents for any
series of Securities, it will, prior to each due date of the principal of (and
premium, if any) or interest on any Securities of that series, deposit with the
paying agent a sum sufficient to pay the principal (and premium, if any) or
interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled to such principal, premium or interest, and (unless such paying
agent is the Trustee) the Company will promptly notify the Trustee of this
action or failure so to act.

     

    (c)           Notwithstanding
anything in this Section to the contrary, (i) the agreement to hold sums in
trust as provided in this Section is subject to the provisions of Section 11.05,
and (ii) 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
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
terms and conditions as those upon which such sums were held by the Company or
such paying agent; and, upon such payment by the Company or any paying agent to
the Trustee, the Company or such paying agent shall be released from all further
liability with respect to such money.

     

    Section
4.04    Appointment To Fill Vacancy In Office
Of Trustee.

     

    The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 7.10, a Trustee, so that there

    The
Company will furnish or cause to be furnished to the Trustee (a) within 15 days
after each regular record date (as defined in Section 2.03) a list, in such form
as the Trustee may reasonably require, of the names and addresses of the holders
of each series of Securities as of such regular record date, provided that the
Company shall not be obligated to furnish or cause to furnish such list at any
time that the list shall not differ in any respect from the most recent list
furnished to the Trustee by the Company and (b) at such other times as the
Trustee may request in writing within 30 days after the receipt by the Company
of any such request, a list of similar form and content as of a date not more
than 15 days prior to the time such list is furnished; provided, however, that,
in either case, no such list need be furnished for any series for which the
Trustee shall be the Security Registrar.

     

    Section
5.02    Preservation Of Information;
Communications With Securityholders.

     

    (a)           The
Trustee shall preserve, in as current a form as is reasonably practicable, all
information as to the names and addresses of the holders of Securities contained
in the most recent list furnished to it as provided in Section 5.01 and as to
the names and addresses of holders of Securities received by the Trustee in its
capacity as Security Registrar (if acting in such capacity).

     

    (b)           The
Trustee may destroy any list furnished to it as provided in Section 5.01 upon
receipt of a new list so furnished.

     

    (c)           Securityholders
may communicate as provided in Section 312(b) of the Trust Indenture Act with
other Securityholders with respect to their rights under this Indenture or under
the Securities, and, in connection with any such communications, the Trustee
shall satisfy its obligations under Section 312(b) of the Trust Indenture Act in
accordance with the provisions of Section 312(b) of the Trust Indenture
Act.

     

    Section
5.03    Reports By The
Company.

     

    (a)           The
Company covenants and agrees to provide (which delivery may be via electronic
mail) to the Trustee within 30 days, after the Company files the same with the
Commission, copies of the annual reports and of the information, documents and
other reports (or copies of such portions of any of the foregoing as the
Commission may from time to time by rules and regulations prescribe) that the
Company is required to file with the Commission pursuant to Section 13 or
Section 15(d) of the Exchange Act; provided, however, the Company shall not be
required to deliver to the Trustee any materials for which the Company has
sought and received confidential treatment by the Commission; and provided
further, that so long as such filings by the Company are available on the
Commission’s Electronic Data Gathering, Analysis and Retrieval System (EDGAR),
or Interactive Data Electronic Applications (IDEA), or any successor system,
such filings shall be deemed to have been filed with the Trustee for purposes
hereof without any further action required by the Company; provided that an
electronic link to such filing, together with an electronic notice of such
filing have been sent to the Trustee.  For the avoidance of doubt, a
failure by the Company to file annual reports, information and other reports
with the SEC within the time period prescribed thereof by the Commission shall
not be deemed a breach of this Section 5.03.

    (b)           Delivery
of reports, information and documents to the Trustee under Section 5.03 is for
informational purposes only and the information 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 thereunder (as to which the
Trustee is entitled to rely exclusively on an Officer’s
Certificate).

     

    Section
5.04    Reports By The Trustee.

    REMEDIES
OF THE TRUSTEE AND SECURITYHOLDERS ON EVENT OF DEFAULT

     

    Section
6.01    Events Of Default.

     

    (a)           Whenever
used herein with respect to Securities of a particular series, “Event of
Default” means any one or more of the following events that has occurred and is
continuing:

     

    (1)           the
Company defaults in the payment of any installment of interest upon any of the
Securities of that series, as and when the same shall become due and payable,
and such default continues for a period of 90 days; provided, however, that a
valid extension of an interest payment period by the Company in accordance with
the terms of any indenture supplemental hereto shall not constitute a default in
the payment of interest for this purpose;

     

    (2)           the
Company defaults in the payment of the principal of (or premium, if any, on) any
of the Securities of that series as and when the same shall become due and
payable whether at maturity, upon redemption, by declaration or otherwise, or in
any payment required by any sinking or analogous fund established with respect
to that series; provided, however, that a valid extension of the maturity of
such Securities in accordance with the terms of any indenture supplemental
hereto shall not constitute a default in the payment of principal or premium, if
any;


    
      
         


      

      
        21

        
          

        

      

      
         


      

    


    (3)           the
Company fails to observe or perform any other of its covenants or agreements
with respect to that series contained in this Indenture or otherwise established
with respect to that series of Securities pursuant to Section 2.01 hereof (other
than a covenant or agreement that has been expressly included in this Indenture
solely for the benefit of one or more series of Securities other than such
series) for a period of 90 days after the date on which written notice of such
failure, requiring the same to be remedied and stating that such notice is a
“Notice of Default” hereunder, shall have been given to the Company by the
Trustee, by registered or certified mail, or to the Company and the Trustee by
the holders of at least 25% in principal amount of the Securities of that series
at the time Outstanding;

     

    (4)           the
Company pursuant to or within the meaning of any Bankruptcy Law (i) commences a
voluntary case, (ii) consents to the entry of an order for relief against it in
an involuntary case, (iii) consents to the appointment of a Custodian of it or
for all or substantially all of its property or (iv) makes a general assignment
for the benefit of its creditors; or

     

    (5)           a
court of competent jurisdiction enters an order under any Bankruptcy Law that
(i) is for relief against the Company in an involuntary case, (ii) appoints a
Custodian of the Company for all or substantially all of its property or (iii)
orders the liquidation of the Company, and the order or decree remains unstayed
and in effect for 90 days.

     

    (b)           In
each and every such case (other than an Event of Default specified in clause (4)
or clause (5) above), unless the principal of all the Securities of that series
shall have already become due and payable, either the Trustee or the holders of
not less than 25% in aggregate principal amount of the Securities of that series
then Outstanding hereunder, by notice in writing to the Company (and to the
Trustee if given by such Securityholders), may declare the principal of (and
premium, if any, on) and accrued and unpaid interest on all the Securities of
that series to be due and payable immediately, and upon any such declaration the
same shall become and shall be immediately due and payable. If an Event of
Default specified in clause (4) or clause (5) above occurs, the principal of and
accrued and unpaid interest on all the Securities of that series shall
automatically be immediately due and payable without any declaration or other
act on the part of the Trustee or the holders of the Securities.

     

    (c)           At
any time after the principal of (and premium, if any, on) and accrued and unpaid
interest on the Securities of that series shall have been so declared due and
payable, and before any judgment or decree for the payment of the moneys due
shall have been obtained or entered as hereinafter provided, the holders of a
majority in aggregate principal amount of the Securities of that series then
Outstanding hereunder, by written notice to the Company and the Trustee, may
rescind and annul such declaration and its consequences if: (i) the Company has
paid or deposited with the Trustee a sum sufficient to pay all matured
installments of interest upon all the Securities of that series and the
principal of (and premium, if any, on) any and all Securities of that series
that shall have become due otherwise than by acceleration (with interest upon
such principal and premium, if any, and, to the extent that such payment is
enforceable under applicable law, upon overdue installments of interest, at the
rate per annum expressed in the Securities of that series to the date of such
payment or deposit) and the amount payable to the Trustee under Section 7.06,
and (ii) any and all Events of Default under the Indenture with respect to such
series, other than the nonpayment of principal on (and premium, if any, on) and
accrued and unpaid interest on Securities of that series that shall not have
become due by their terms, shall have been remedied or waived as provided in
Section 6.06.

    No such
rescission and annulment shall extend to or shall affect any subsequent default
or impair any right consequent thereon.

     

    (d)           In
case the Trustee shall have proceeded to enforce any right with respect to
Securities of that series under this Indenture and such proceedings shall have
been discontinued or abandoned because of such rescission or annulment or for
any other reason or shall have been determined adversely to the Trustee, then
and in every such case, subject to any determination in such proceedings, the
Company and the Trustee shall be restored respectively to their former positions
and rights hereunder, and all rights, remedies and powers of the Company and the
Trustee shall continue as though no such proceedings had been
taken.

     

    Section
6.02    Collection Of Indebtedness And Suits For Enforcement
By Trustee.

     

    (a)           The
Company covenants that (i) in case it shall default in the payment of any
installment of interest on any of the Securities of a series, or in any payment
required by any sinking or analogous fund established with respect to that
series as and when the same shall have become due and payable, and such default
shall have continued for a period of 90 days, or (ii) in case it shall default
in the payment of the principal of (or premium, if any, on) any of the
Securities of a series when the same shall have become due and payable, whether
upon maturity of the Securities of a series or upon redemption or upon
declaration or otherwise then, upon demand of the Trustee, the Company will pay
to the Trustee, for the benefit of the holders of the Securities of that series,
the whole amount that then shall have been become due and payable on all such
Securities for principal (and premium, if any) or interest, or both, as the case
may be, with interest upon the overdue principal (and premium, if any) and (to
the extent that payment of such interest is enforceable under applicable law)
upon overdue installments of interest at the rate per annum expressed in the
Securities of that series; and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, and the
amount payable to the Trustee under Section 7.06.

     

    (b)           If
the Company shall fail to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, shall be entitled
and empowered to institute any action or proceedings at law or in equity for the
collection of the sums so due and unpaid, and may prosecute any such action or
proceeding to judgment or final decree, and may enforce any such judgment or
final decree against the Company or other obligor upon the Securities of that
series and collect the moneys adjudged or decreed to be payable in the manner
provided by law or equity out of the property of the Company or other obligor
upon the Securities of that series, wherever situated.

    (c)           In
case of any receivership, insolvency, liquidation, bankruptcy, reorganization,
readjustment, arrangement, composition or judicial proceedings affecting the
Company, or its creditors or property, the Trustee shall have power to intervene
in such proceedings and take any action therein that may be permitted by the
court and shall (except as may be otherwise provided by law) be entitled to file
such proofs of claim and other papers and documents as may be necessary or
advisable in order to have the claims of the Trustee and of the holders of
Securities of such series allowed for the entire amount due and payable by the
Company under the Indenture at the date of institution of such proceedings and
for any additional amount that may become due and payable by the Company after
such date, and to collect and receive any moneys or other property payable or
deliverable on any such claim, and to distribute the same after the deduction of
the amount payable to the Trustee under Section 7.06; and any receiver, assignee
or trustee in bankruptcy or reorganization is hereby authorized by each of the
holders of Securities of such series to make such payments to the Trustee, and,
in the event that the Trustee shall consent to the making of such payments
directly to such Securityholders, to pay to the Trustee any amount due it under
Section 7.06.

     

    (d)           All
rights of action and of asserting claims under this Indenture, or under any of
the terms established with respect to Securities of that series, may be enforced
by the Trustee without the possession of any of such Securities, or the
production thereof at any trial or other proceeding relative thereto, and any
such suit or proceeding instituted by the Trustee shall be brought in its own
name as trustee of an express trust, and any recovery of judgment shall, after
provision for payment to the Trustee of any amounts due under Section 7.06, be
for the ratable benefit of the holders of the Securities of such
series.

     

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

     

    Nothing
contained herein 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 that 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
proceeding.

     

    Section
6.03    Application Of Moneys
Collected.

     

    Any
moneys collected by the Trustee pursuant to this Article with respect to a
particular series of Securities shall be applied in the following order, at the
date or dates fixed by the Trustee and, in case of the distribution of such
moneys on account of principal (or premium, if any) or interest, upon
presentation of the Securities of that series, and notation thereon of the
payment, if only partially paid, and upon surrender thereof if fully
paid:

the payment of reasonable costs and expenses of collection and of all amounts
payable to the Trustee under Section 7.06;

     

    SECOND:

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 premium, if any) and interest, respectively;
and

    THIRD: To
the payment of the remainder, if any, to the Company or any other Person
lawfully entitled thereto.

     

    Section
6.04    Limitation On
Suits.

     

    No holder
of any Security of any series shall have any right by virtue or by availing of
any provision of this Indenture to institute any suit, action or proceeding in
equity or at law upon or under or with respect to this Indenture or for the
appointment of a receiver or trustee, or for any other remedy hereunder, unless
(i) such holder previously shall have given to the Trustee written notice of an
Event of Default and of the continuance thereof with respect to the Securities
of such series specifying such Event of Default, as hereinbefore provided; (ii)
the holders of not less than 25% in aggregate principal amount of the Securities
of such series then Outstanding shall have made written request upon the Trustee
to institute such action, suit or proceeding in its own name as Trustee
hereunder; (iii) such holder or holders shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby; (iv) the Trustee for 90 days
after its receipt of such notice, request and offer of indemnity, shall have
failed to institute any such action, suit or proceeding; and (v) during such 90
day period, the holders of a majority in principal amount of the Securities of
that series do not give the Trustee a direction inconsistent with the
request.

     

    Notwithstanding
anything contained herein to the contrary or any other provisions of this
Indenture, the right of any holder of any Security to receive payment of the
principal of (and premium, if any) and interest on such Security, as therein
provided, on or after the respective due dates expressed in such Security (or in
the case of redemption, on the redemption date), or to institute suit for the
enforcement of any such payment on or after such respective dates or redemption
date, shall not be impaired or affected without the consent of such holder and
by accepting a Security hereunder it is expressly understood, intended and
covenanted by the taker and holder of every Security of such series with every
other such taker and holder and the Trustee, that no one or more holders of
Securities of such series shall have any right in any manner whatsoever by
virtue or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of the holders of any other of such Securities, or to
obtain or seek to obtain priority over or preference to any other such holder,
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all holders of
Securities of such series. For the protection and enforcement of the provisions
of this Section, each and every Securityholder and the Trustee shall be entitled
to such relief as can be given either at law or in equity.

     

    Section
6.05    Rights And Remedies Cumulative; Delay Or Omission
Not Waiver.

     

    (a)           Except
as otherwise provided in Section 2.07, all powers and remedies given by this
Article to the Trustee or to the Securityholders shall, to the extent permitted
by law, be deemed cumulative and not exclusive of any other powers and remedies
available to the Trustee or the holders of the Securities, by judicial
proceedings or otherwise, to enforce the performance or observance of the
covenants and agreements contained in this Indenture or otherwise established
with respect to such Securities.

    (b)           No
delay or omission of the Trustee or of any holder of any of the Securities to
exercise any right or power accruing upon any Event of Default occurring and
continuing as aforesaid shall impair any such right or power, or shall be
construed to be a waiver of any such default or an acquiescence therein; and,
subject to the provisions of Section 6.04, every power and remedy given by this
Article or by law to the Trustee or the Securityholders may be exercised from
time to time, and as often as shall be deemed expedient, by the Trustee or by
the Securityholders.

     

    Section
6.06    Control By
Securityholders.

     

    The
holders of a majority in aggregate principal amount of the Securities of any
series at the time Outstanding, determined in accordance with Section 8.04,
shall have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred on the Trustee with respect to such series; provided, however,
that such direction shall not be in conflict with any rule of law or with this
Indenture or subject the Trustee in its sole discretion to personal
liability.  Subject to the provisions of Section 7.01, the Trustee
shall have the right to decline to follow any such direction if the Trustee in
good faith shall, by a Responsible Officer or officers of the Trustee, determine
that the proceeding so directed, subject to the Trustee’s duties under the Trust
Indenture Act, would involve the Trustee in personal liability or might be
unduly prejudicial to the Securityholders not involved in the proceeding. The
holders of a majority in aggregate principal amount of the Securities of any
series at the time Outstanding affected thereby, determined in accordance with
Section 8.04, may on behalf of the holders of all of the Securities of such
series waive any past default in the performance of any of the covenants
contained herein or established pursuant to Section 2.01 with respect to such
series and its consequences, except a default in the payment of the principal
of, or premium, if any, or interest on, any of the Securities of that series as
and when the same shall become due by the terms of such Securities otherwise
than by acceleration (unless such default has been cured and a sum sufficient to
pay all matured installments of interest and principal and any premium has been
deposited with the Trustee (in accordance with Section 6.01(c)). Upon any such
waiver, the default covered thereby shall be deemed to be cured for all purposes
of this Indenture and the Company, the Trustee and the holders of the Securities
of such series shall be restored to their former positions and rights hereunder,
respectively; but no such waiver shall extend to any subsequent or other default
or impair any right consequent thereon.

     

    Section
6.07    Undertaking To Pay
Costs.

     

    All
parties to this Indenture agree, and each holder of any Securities by such
holder’s acceptance thereof shall be deemed to have agreed, that any court may
in its discretion require, in any suit for the enforcement of any right or
remedy under this Indenture, or in any suit against the Trustee for any action
taken or omitted by it as Trustee, the filing by any party litigant in such suit
of an undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys’ fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder, or group of
Securityholders, holding more than 10% in aggregate principal amount of the
Outstanding Securities of any series, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of (or
premium, if any) or interest on any Security of such series, on or after the
respective due dates expressed in such Security or established pursuant to this
Indenture.

    CONCERNING
THE TRUSTEE

     

    Section
7.01    Certain Duties And Responsibilities Of
Trustee.

     

    (a)           The
Trustee, prior to the occurrence of an Event of Default with respect to the
Securities of a series and after the curing of all Events of Default with
respect to the Securities of that series that may have occurred, shall undertake
to perform with respect to the Securities of such series such duties and only
such duties as are specifically set forth in this Indenture, and no implied
covenants shall be read into this Indenture against the Trustee. In case an
Event of Default with respect to the Securities of a series has occurred (that
has not been cured or waived), the Trustee shall exercise with respect to
Securities of that series 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 man would exercise or use under the circumstances in the conduct of his
own affairs.

     

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

     

    (i)           prior
to the occurrence of an Event of Default with respect to the Securities of a
series and after the curing or waiving of all such Events of Default with
respect to that series that may have occurred:

     

    (A)           the
duties and obligations of the Trustee shall with respect to the Securities of
such series be determined solely by the express provisions of this Indenture,
and the Trustee shall not be liable with respect to the Securities of such
series except for the performance of such duties and obligations as are
specifically set forth in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee;
and

     

    (B)           in
the absence of bad faith on the part of the Trustee, the Trustee may with
respect to the Securities of such series conclusively rely, as to the truth of
the statements and the correctness of the opinions expressed therein, upon any
certificates or opinions furnished to the Trustee and conforming to the
requirements of this Indenture; but in the case of any such certificates or
opinions that 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;

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

     

    (iii)           the
Trustee shall not be liable with respect to any action taken or omitted to be
taken by it in good faith in accordance with the direction of the holders of not
less than a majority in principal amount of the Securities of any series at the
time Outstanding relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or
power conferred upon the Trustee under this Indenture with respect to the
Securities of that series; and

     

    (iv)           None
of the provisions contained in this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur personal financial liability in
the performance of any of its duties or in the exercise of any of its rights or
powers if there is reasonable ground for believing that the repayment of such
funds or liability is not reasonably assured to it under the terms of this
Indenture or adequate indemnity against such risk is not reasonably assured to
it.

     

    Section
7.02    Certain Rights Of
Trustee.  Except as otherwise provided in Section
7.01:

     

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

     

    (b)           Any
request, direction, order or demand of the Company mentioned herein shall be
sufficiently evidenced by a Board Resolution or an instrument signed in the name
of the Company by any authorized officer of the Company (unless other evidence
in respect thereof is specifically prescribed herein);

     

    (c)           The
Trustee may consult with counsel and the written advice of such counsel or, if
requested, any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken or suffered or omitted hereunder in
good faith and in reliance thereon;

     

    (d)           The
Trustee shall be under no obligation to exercise any of the rights or powers
vested in it by this Indenture at the request, order or direction of any of the
Securityholders pursuant to the provisions of this Indenture, unless such
Securityholders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities that may be incurred
therein or thereby; nothing contained herein shall, however, relieve the Trustee
of the obligation, upon the occurrence of an Event of Default with respect to a
series of the Securities (that has not been cured or waived), to exercise with
respect to Securities of that series such of the rights and powers vested in it
by this Indenture, and to use the same degree of care and skill in their
exercise, as a prudent man would exercise or use under the circumstances in the
conduct of his own affairs;


    
      
         


      

      
        28

        
          

        

      

      
         


      

    


    (e)           The
Trustee shall not be liable for any action taken or omitted to be taken by it in
good faith and believed by it to be authorized or within the discretion or
rights or powers conferred upon it by this Indenture;

     

    (f)           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, consent, order, approval, bond, security, or other papers or
documents, unless requested in writing so to do by the holders of not less than
a majority in principal amount of the Outstanding Securities of the particular
series affected thereby (determined as provided in Section 8.04); provided,
however, that if the payment within a reasonable time to the Trustee of the
costs, expenses or liabilities likely to be incurred by it in the making of such
investigation is, in the opinion of the Trustee, not reasonably assured to the
Trustee by the security afforded to it by the terms of this Indenture, the
Trustee may require reasonable indemnity against such costs, expenses or
liabilities as a condition to so proceeding. The reasonable expense of every
such examination shall be paid by the Company or, if paid by the Trustee, shall
be repaid by the Company upon demand;

     

    (g)           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;

     

    (h)           In
no event shall the Trustee be responsible or liable for any failure or delay in
the performance of its obligations hereunder arising out of or caused by,
directly or indirectly, forces beyond its control, including, without
limitation, strikes, work stoppages, accidents, acts of war or terrorism, civil
or military disturbances, nuclear or natural catastrophes or acts of God, and
interruptions, loss or malfunctions of utilities, communications or computer
(software and hardware) services; it being understood that the Trustee shall use
reasonable efforts which are consistent with accepted practices in the banking
industry to resume performance as soon as practicable under the
circumstances;

     

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

     

    (j)           The
Trustee agrees to accept and act upon instructions or directions pursuant to
this Indenture sent by unsecured e-mail, facsimile transmission or other similar
unsecured electronic methods; provided, however, that (a) the party providing
such written instructions, subsequent to such transmission of written
instructions, shall provide the originally executed instructions or directions
to the Trustee in a timely manner, and (b) such originally executed instructions
or directions shall be signed by an authorized representative of the party
providing such instructions or directions.  If the party elects to
give the Trustee e-mail or facsimile instructions (or instructions by a similar
electronic method) and the Trustee in its discretion elects to act upon such
instructions, the Trustee’s understanding of such instructions shall be deemed
controlling.  The Trustee shall not be liable for any losses, costs or
expenses arising directly or indirectly from the Trustee’s reliance upon and
compliance with such instructions notwithstanding such instructions conflict or
are inconsistent with a subsequent written instruction.  The party
providing electronic instructions agrees to assume all risks arising out of the
use of such electronic methods to submit instructions and directions to the
Trustee, including without limitation the risk of the Trustee acting on
unauthorized instructions, and the risk or interception and misuse by third
parties.

    In
addition, the Trustee shall not be deemed to have knowledge of any Default or
Event of Default until the Trustee shall have received written notification in
the manner set forth in this Indenture or a Responsible Officer of the Trustee
shall have obtained actual knowledge.

     

    Section
7.03    Trustee Not Responsible For Recitals Or Issuance Or
Securities.

     

    (a)           The
recitals contained herein and in the Securities shall be taken as the statements
of the Company, and the Trustee assumes no responsibility for the correctness of
the same.

     

    (b)           The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities.

     

    (c)           The
Trustee shall not be accountable for the use or application by the Company of
any of the Securities or of the proceeds of such Securities, or for the use or
application of any moneys paid over by the Trustee in accordance with any
provision of this Indenture or established pursuant to Section 2.01, or for the
use or application of any moneys received by any paying agent other than the
Trustee.

     

    Section
7.04    May Hold
Securities.

     

    The
Trustee or any paying agent or Security Registrar, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not Trustee, paying agent or Security
Registrar.

     

    Section
7.05    Moneys Held In
Trust.

     

    Subject
to the provisions of Section 11.05, all moneys received by the Trustee shall,
until used or applied as herein provided, be held in trust for the purposes for
which they were received, but 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 moneys received by it hereunder except such as it may agree with the
Company to pay thereon.

     

    Section
7.06    Compensation And
Reimbursement.

     

    (a)           The
Company covenants and agrees to pay to the Trustee, and the Trustee shall be
entitled to, such reasonable compensation (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
as the Company and the Trustee may from time to time agree in writing, for all
services rendered by it in the execution of the trusts hereby created and in the
exercise and performance of any of the powers and duties hereunder of the
Trustee, and, except as otherwise expressly provided herein, the Company will
pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all Persons not
regularly in its employ), except any such expense, disbursement or advance as
may arise from its negligence or bad faith and except as the Company and Trustee
may from time to time agree in writing. The Company also covenants to indemnify
the Trustee (and its officers, agents, directors and employees) for, and to hold
it harmless against, any loss, liability or expense incurred without negligence
or bad faith on the part of the Trustee and arising out of or in connection with
the acceptance or administration of this trust, including the reasonable costs
and expenses of defending itself against any claim of liability in the
premises.


    
      
         


      

      
        30

        
          

        

      

      
         


      

    


    (b)           The
obligations of the Company under this Section to compensate and indemnify the
Trustee and to pay or reimburse the Trustee for reasonable expenses,
disbursements and advances shall constitute additional indebtedness hereunder.
Such additional indebtedness shall be secured by a lien prior to that of the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the holders of particular
Securities.

     

    (c)           To
ensure the Company’s payment obligations in this Section, the Trustee shall have
a lien prior to the Securities on all funds or property held or collected by the
Trustee, except that held in trust to pay principal of or interest on particular
Securities.  When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 6.01(4) or (5), the
expenses (including the reasonable fees and expenses of its counsel) and the
compensation for services in connection therewith are to constitute expenses of
administration under any bankruptcy law.  The provisions of this
Section 7.06 shall survive the termination of this Indenture and the resignation
or removal of the Trustee.

     

    Section
7.07    Reliance On Officer’s
Certificate.

     

    Except as
otherwise provided in Section 7.01, whenever in the administration of the
provisions of this Indenture the Trustee shall deem it reasonably necessary or
desirable that a matter be proved or established prior to taking or suffering or
omitting to take any action hereunder, such matter (unless other evidence in
respect thereof be herein specifically prescribed) may, in the absence of
negligence or bad faith on the part of the Trustee, be deemed to be conclusively
proved and established by an Officer’s Certificate delivered to the Trustee and
such certificate, in the absence of negligence or bad faith on the part of the
Trustee, shall be full warrant to the Trustee for any action taken, suffered or
omitted to be taken by it under the provisions of this Indenture upon the faith
thereof.

     

    Section
7.08    Disqualification; Conflicting
Interests.

     

    If the
Trustee has or shall acquire any “conflicting interest” within the meaning of
Section 310(b) of the Trust Indenture Act, the Trustee and the Company
shall in all respects comply with the provisions of Section 310(b) of the
Trust Indenture Act.

     

    Section
7.09    Corporate Trustee Required;
Eligibility.

     

    There
shall at all times be a Trustee with respect to the Securities issued hereunder
which shall at all times be a corporation organized and doing business under the
laws of the United States of America or any state or territory thereof or of the
District of Columbia, or a corporation or other Person permitted to act as
trustee by the Commission, authorized under such laws to exercise corporate
trust powers, having a combined capital and surplus of at least fifty million
U.S. dollars ($50,000,000), and subject to supervision or examination by
federal, state, territorial, or District of Columbia authority.


    
      
         


      

      
        31

        
          

        

      

      
         


      

    


    If such
corporation or other Person publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation or other Person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published. The Company may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Company, serve as
Trustee. In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, the Trustee shall resign
immediately in the manner and with the effect specified in Section
7.10.

     

    Section
7.10    Resignation And Removal; Appointment Of
Successor.

     

    (a)           The
Trustee or any successor hereafter appointed may at any time resign with respect
to the Securities of one or more series by giving written notice thereof to the
Company and by transmitting notice of resignation by mail, first class postage
prepaid, to the Securityholders of such series, as their names and addresses
appear upon the Security Register.  Upon receiving such notice of
resignation, the Company shall promptly appoint a successor trustee with respect
to Securities of such series by written instrument, in duplicate, executed by
order of the Board of Directors, one copy of which instrument shall be delivered
to the resigning Trustee and one copy to the successor trustee. If no successor
trustee shall have been so appointed and have accepted appointment within 30
days after the mailing 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 Securities of such series, or any Securityholder of that
series who has been a bona fide holder of a Security or Securities for at least
six months may on behalf of himself and all others similarly situated, petition
any such court for the appointment of a successor trustee. Such court may
thereupon after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

     

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

     

    (i)           the
Trustee shall fail to comply with the provisions of Section 7.08 after written
request therefor by the Company or by any Securityholder who has been a bona
fide holder of a Security or Securities for at least six months; or

     

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

     

    (iii)           the
Trustee shall become incapable of acting, or shall be adjudged a bankrupt or
insolvent, or commence a voluntary bankruptcy proceeding, or a receiver of the
Trustee or of its property shall be appointed or consented to, 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;


    
      
         


      

      
        32

        
          

        

      

      
         


      

    


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

     

    (c)           The
holders of a majority in aggregate principal amount of the Securities of any
series at the time Outstanding may at any time remove the Trustee with respect
to such series by so notifying the Trustee and the Company and may appoint a
successor Trustee for such series with the consent of the Company.

     

    (d)           Any
resignation or removal of the Trustee and appointment of a successor trustee
with respect to the Securities of a series pursuant to any of the provisions of
this Section shall become effective upon acceptance of appointment by the
successor trustee as provided in Section 7.11.

     

    (e)           Any
successor trustee appointed pursuant to this Section may be appointed with
respect to the Securities of one or more series or all of such series, and at
any time there shall be only one Trustee with respect to the Securities of any
particular series.

     

    Section
7.11    Acceptance Of Appointment By Successor.

     

    (a)           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,
transfer and deliver to such successor trustee all property and money held by
such retiring Trustee hereunder.


    
      
         


      

      
        33

        
          

        

      

      
         


      

    


    (b)           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 (i) 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, (ii) 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 (iii) 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, 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 that no Trustee shall be responsible for any act or failure to
act on the part of any other Trustee hereunder; 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, such
retiring Trustee shall with respect to the Securities of that or those series to
which the appointment of such successor trustee relates have no further
responsibility for the exercise of rights and powers or for the performance of
the duties and obligations vested in the Trustee under this Indenture, 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, to the extent contemplated by such
supplemental indenture, the 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.

     

    (c)           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 paragraph
(a) or (b) of this Section, as the case may be.

     

    (d)           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.

     

    (e)           Upon
acceptance of appointment by a successor trustee as provided in this Section,
the Company shall transmit notice of the succession of such trustee hereunder by
mail, first class postage prepaid, to the Securityholders, as their names and
addresses appear upon the Security Register.  If the Company fails to
transmit such notice within ten days after acceptance of appointment by the
successor trustee, the successor trustee shall cause such notice to be
transmitted at the expense of the Company.

     

    Section
7.12    Merger, Conversion, Consolidation Or
Succession To Business.

     

    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 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 that such corporation shall be qualified under
the provisions of Section 7.08 and eligible under the provisions of Section
7.09, without the execution or filing of any paper or any further act on the
part of any of the parties hereto, anything herein to the contrary
notwithstanding. 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.

    Section
7.13    Preferential Collection Of Claims
Against The Company.

     

    The
Trustee shall comply with Section 311(a) of the Trust Indenture Act, excluding
any creditor relationship described in Section 311(b) of the Trust Indenture
Act. A Trustee who has resigned or been removed shall be subject to Section
311(a) of the Trust Indenture Act to the extent included therein.

     

    Section
7.14    Notice Of
Default.

     

    If any
Event of Default occurs and is continuing and if such Event of Default is known
to a Responsible Officer of the Trustee, the Trustee shall mail to each
Securityholder in the manner and to the extent provided in Section 313(c) of the
Trust Indenture Act notice of the Event of Default within the earlier of 90 days
after it occurs and 30 days after it is known to a Responsible Officer of the
Trustee or written notice of it is received by the Trustee, unless such Event of
Default has been cured; provided, however, that,
except in the case of a default in the payment of the principal of (or premium,
if any) or interest on any Security, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or 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
interest of the Securityholders..

    CONCERNING
THE SECURITYHOLDERS

     

    Section
8.01    Evidence Of Action By
Securityholders.

     

    Whenever
in this Indenture it is provided that the holders of a majority or specified
percentage in aggregate principal amount of the Securities of a particular
series may take any action (including the making of any demand or request, the
giving of any notice, consent or waiver or the taking of any other action), the
fact that at the time of taking any such action the holders of such majority or
specified percentage of that series have joined therein may be evidenced by any
instrument or any number of instruments of similar tenor executed by such
holders of Securities of that series in person or by agent or proxy appointed in
writing.

     

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

to the provisions of Section 7.01, proof of the execution of any instrument by a
Securityholder (such proof will not require notarization) or his agent or proxy
and proof of the holding by any Person of any of the Securities shall be
sufficient if made in the following manner:

     

    (a)           The
fact and date of the execution by any such Person of any instrument may be
proved in any reasonable manner acceptable to the Trustee.

     

    (b)           The
ownership of Securities shall be proved by the Security Register of such
Securities or by a certificate of the Security Registrar thereof.

     

    The
Trustee may require such additional proof of any matter referred to in this
Section as it shall deem necessary.

     

    Section
8.03    Who May Be Deemed
Owners.

     

    Prior to
the due presentment for registration of transfer of any Security, the Company,
the Trustee, any paying agent and any Security Registrar may deem and treat the
Person in whose name such Security shall be registered upon the books of the
Company as the absolute owner of such Security (whether or not such Security
shall be overdue and notwithstanding any notice of ownership or writing thereon
made by anyone other than the Security Registrar) for the purpose of receiving
payment of or on account of the principal of, premium, if any, and (subject to
Section 2.03) interest on such Security and for all other purposes; and neither
the Company nor the Trustee nor any paying agent nor any Security Registrar
shall be affected by any notice to the contrary.

     

    Section
8.04    Certain Securities Owned By Company
Disregarded.

     

    In
determining whether the holders of the requisite aggregate principal amount of
Securities of a particular series have concurred in any direction, consent or
waiver under this Indenture, the Securities of that series that are owned by the
Company or any other obligor on the Securities of that series or by any Person
directly or indirectly controlling or controlled by or under common control with
the Company or any other obligor on the Securities of that series shall be
disregarded and deemed not to be Outstanding for the purpose of any such
determination, except that for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, consent or waiver, only
Securities of such series that the Trustee actually knows are so owned shall be
so disregarded. The Securities so owned that have been pledged in good faith may
be regarded as Outstanding for the purposes of this Section, if the pledgee
shall establish to the satisfaction of the Trustee the pledgee’s right so to act
with respect to such Securities and that the pledgee is not a Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any such other obligor. In case of a dispute as to
such right, any decision by the Trustee taken upon the advice of counsel shall
be full protection to the Trustee.

8.05    Actions Binding On Future
Securityholders.

     

    At any
time prior to (but not after) the evidencing to the Trustee, as provided in
Section 8.01, of the taking of any action by the holders of the majority or
percentage in aggregate principal amount of the Securities of a particular
series specified in this Indenture in connection with such action, any holder of
a Security of that series that is shown by the evidence to be included in the
Securities the holders of which have consented to such action may, by filing
written notice with the Trustee, and upon proof of holding as provided in
Section 8.02, revoke such action so far as concerns such
Security.  Except as aforesaid any such action taken by the holder of
any Security shall be conclusive and binding upon such holder and upon all
future holders and owners of such Security, and of any Security issued in
exchange therefor, on registration of transfer thereof or in place thereof,
irrespective of whether or not any notation in regard thereto is made upon such
Security. Any action taken by the holders of the majority or percentage in
aggregate principal amount of the Securities of a particular series specified in
this Indenture in connection with such action shall be conclusively binding upon
the Company, the Trustee and the holders of all the Securities of that
series.

the mailing of, such notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such supplemental
indenture.

    Section
13.08  Payments On Business Days.

     

    Except as
provided pursuant to Section 2.01 pursuant to a Board Resolution, and set forth
in an Officer’s Certificate, or established in one or more indentures
supplemental to this Indenture, in any case where the date of maturity of
interest or principal of any Security or the date of redemption of any Security
shall not be a Business Day, then payment of interest or principal (and premium,
if any) may be made on the next succeeding Business Day with the same force and
effect as if made on the nominal date of maturity or redemption, and no interest
shall accrue for the period after such nominal date.

     

    Section
13.09  Conflict With Trust Indenture Act.

     

    If and to
the extent that any provision of this Indenture limits, qualifies or conflicts
with the duties imposed by Sections 310 to 317, inclusive, of the Trust
Indenture Act, such imposed duties shall control.

     

    Section
13.10  Counterparts.

     

    This
Indenture may be executed in any number of counterparts, each of which shall be
an original, but such counterparts shall together constitute but one and the
same instrument.

     

    Section
13.11  Separability.

     

    In case
any one or more of the provisions contained in this Indenture or in the
Securities of any series shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Indenture or of such Securities,
but this Indenture and such Securities shall be construed as if such invalid or
illegal or unenforceable provision had never been contained herein or
therein.

     

    Section
13.12  Compliance Certificates.

     

    The
Company shall deliver to the Trustee, within 120 days after the end of each
fiscal year during which any Securities of any series were outstanding, an
officer’s certificate stating whether or not the signers know of any Event of
Default that occurred during such fiscal year. Such certificate shall contain a
certification from the principal executive officer, principal financial officer
or principal accounting officer of the Company that a review has been conducted
of the activities of the Company and the Company’s performance under this
Indenture and that the Company has complied with all conditions and covenants
under this Indenture. For purposes of this Section 13.12, such compliance shall
be determined without regard to any period of grace or requirement of notice
provided under this Indenture. If the officer of the Company signing such
certificate has knowledge of such an Event of Default, the certificate shall
describe any such Event of Default and its status.

Whereof, the parties hereto have caused this Indenture to be duly
executed all as of the day and year first above written.
