redeemed in part, the portion thereof not to be so redeemed.

(f) If the principal amount, and applicable premium, of part, but not
all of a Global Note is paid, then upon surrender to the Trustee of such Global
Note, the Company shall execute, and the Trustee shall authenticate, deliver and
register, a Global Note in an authorized denomination in aggregate principal
amount equal to, and having the same terms, Original Issue Date and series as,
the unpaid portion of such Global Note.

Section 2.07 MUTILATED, DESTROYED, LOST OR STOLEN NOTES.

(a) If any temporary or definitive Note shall become mutilated or be
destroyed, lost or stolen, the Company shall execute, and upon its written
request the Trustee shall authenticate and deliver, a new Note of like form and
principal amount and having the same terms and Original Issue Date and bearing a
number not contemporaneously outstanding, in exchange and substitution for the
mutilated Note, or in lieu of and in substitution for the Note so destroyed,
lost or stolen. In every case the applicant for a substituted Note shall furnish
to the Company, the Trustee and any paying agent or Authenticating Agent 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 of a Note, the applicant shall
also furnish to the Company and to the Trustee evidence to their satisfaction of
the destruction, loss or theft of such Note and of the ownership thereof.

deliver the same upon the written request or authorization of any officer of the
Company. Upon the issuance of any substituted Note, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge that

If any Note which has matured, is about to mature, has been redeemed or called
for redemption shall become mutilated or be destroyed, lost or stolen, the
Company may, instead of issuing a substituted Note, pay or authorize the payment
of the same (without surrender thereof except in the case of a mutilated Note)
if the applicant for such payment shall furnish to the Company, the Trustee and
any paying agent or Authenticating Agent such security or indemnity as may be
required by them to save each of them harmless and, in case of destruction, loss
or theft, evidence satisfactory to the Company and the Trustee of the
destruction, loss or theft of such Note and of the ownership thereof.

(c) Every substituted Note issued pursuant to this Section 2.07 by
virtue of the fact that any Note is mutilated, destroyed, lost or stolen shall
constitute an additional contractual obligation of the Company, whether or not
such destroyed, lost or stolen Note shall be found at any time, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Notes duly issued hereunder. All Notes shall be held and owned
upon the express condition that, to the extent permitted by law, the foregoing

stolen Notes and shall preclude to the full extent permitted by applicable law
any and all other rights or remedies with respect to the replacement or payment
of negotiable instruments or other securities without their surrender.

Notes, the Company may execute and the Trustee shall authenticate and deliver
temporary Notes (printed, lithographed or otherwise reproduced). Temporary Notes
shall be issuable in any authorized denomination and substantially in the form

may be appropriate for temporary Notes, all as may be determined by the Company.
Every such temporary Note shall be authenticated by the Trustee upon the same
conditions and in substantially the same manner, and with the same effect, as
the definitive Notes. Without unreasonable delay the Company shall execute and
shall deliver to the Trustee definitive Notes and thereupon any or all temporary
Notes shall be surrendered in exchange therefor at the corporate trust office of
the Trustee, and the Trustee shall authenticate, deliver and register in
exchange for such temporary Notes an equal aggregate principal amount of
definitive Notes. Such exchange shall be made by the Company at its own expense
and without any charge therefor to the Noteholders. Until so exchanged, the
temporary Notes shall in all respects be entitled to the same benefits under
this Indenture as definitive Notes authenticated and delivered hereunder.

Section 2.09 CANCELLATION OF NOTES PAID, ETC. All Notes surrendered for
the purpose of payment, redemption, exchange or registration of transfer shall
be surrendered to the Trustee for cancellation and promptly cancelled by it and
no Notes shall be issued in lieu thereof except as expressly permitted by this
Indenture. The Company shall surrender to the Trustee any Notes so acquired by
it and such Notes shall be cancelled by the Trustee. No Notes shall be
authenticated in lieu of or in exchange for any Notes so cancelled.

Section 2.10 INTEREST RIGHTS PRESERVED. Each Note delivered under this
Indenture upon transfer of or in exchange for or in lieu of any other Note shall
carry all the rights to interest accrued and unpaid, and to accrue, which were
carried by such other Note, and each such Note shall be so dated that neither
gain nor loss of interest shall result from such transfer, exchange or
substitution.

Section 2.11 SPECIAL RECORD DATE. If and to the extent that the Company
fails to make timely payment or provision for timely payment of interest on any
series of Notes (other than on an Interest Payment Date that is a Maturity
date), that interest shall cease to be payable to the Persons who were the
Noteholders of such series at the applicable Regular Record Date. In that event,
when moneys become available for payment of the interest, the Trustee shall (a)
establish a date of payment of such interest and a Special Record Date for the
payment of that interest, which Special Record Date shall be not more than 15 or
fewer than 10 days prior to the date of the proposed payment and (b) mail notice
of the date of payment and of the Special Record Date not fewer than 10 days
preceding the Special Record Date to each Noteholder of such series at the close
of business on the 15th day preceding the mailing at the address of such
Noteholder, as it appeared on the register for the Notes. On the day so
established by the Trustee the interest shall be payable to the Holders of the
applicable Notes at the close of business on the Special Record Date.

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:

to herein) or a nominee thereof and, unless and until it is exchanged in whole
for the individual Notes represented hereby as provided in the Indenture
referred to below, this Global Note may not be transferred except as a whole by
the Depositary to a nominee of the Depositary or by a nominee of the Depositary
to the Depositary or another nominee of the Depositary or by the Depositary or
any such nominee to a successor Depositary or a nominee of such successor
Depositary. Unless this Global Note is presented by an authorized representative
of The Depository Trust Company (55 ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇), to the
Trustee for registration of transfer, exchange or payment, and any certificate
issued is registered in the name of Cede & Co. or such other name as requested

the rules and regulations of the Depositary.

(b) (i) If at any time the Depositary for a Global Note notifies the
Company that it is unwilling or unable to continue as Depositary for such Global
Note or if at any time the Depositary for the Global Note shall no longer be
eligible or in good standing under the Securities Exchange Act of 1934 or other
applicable statute or regulation, the Company shall appoint a successor
Depositary with respect to such Global Note. If a successor Depositary for such
Global Note is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such ineligibility, the Company's
election pursuant to Section 2.05(c)(vi) hereof shall no longer be effective

Company shall execute, and the Trustee, upon receipt of a Company Order for the
authentication and delivery of individual Notes of such series in exchange for
such Global Note, shall authenticate and deliver, individual Notes of such
series of like tenor and terms in definitive form in an aggregate principal

knowledge thereof.

(ii) (A) The Company may at any time and in its sole discretion determine
that all outstanding (but not less than all) Notes of a series issued or
issuable in the form of one or more Global Notes shall no longer be represented

(B) Within seven days after the occurrence of an Event of
Default with respect to any series of Global Notes, the Company shall execute,
and the Trustee shall authenticate and deliver, Notes of such series in
definitive registered form in any authorized denominations and in aggregate

for such Global Notes.

(iii) In any exchange provided for in any of the preceding two
paragraphs, the Company will execute and the Trustee will authenticate and
deliver individual Notes in definitive registered form in authorized
denominations. Upon the exchange of a Global Note for individual Notes, such
Global Note shall be cancelled by the Trustee. Notes issued in exchange for a
Global Note pursuant to this Section shall be registered in such names and in
such authorized denominations as the Depositary for such Global Note, pursuant
to instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Notes to the Depositary for
delivery to the persons in whose names such Notes are so registered, or if the
Depositary shall refuse or be unable to deliver such Notes, the Trustee shall
deliver such Notes to the persons in whose names such Notes are registered,
unless otherwise agreed upon between the Trustee and the Company, in which event
the Company shall cause the Notes to be delivered to the persons in whose names
such Notes are registered.

(c) Neither the Company, the Trustee, any Authenticating Agent nor
any paying agent shall have any responsibility or liability for any aspect of
the records relating to, or payments made on account of, beneficial ownership
interests of a Global Note or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interest.

the Trustee (subject to Section 2.04(a) hereof) and upon 30 days' written notice
to the Depositary but not prior to the first Interest Payment Date of the
respective Global Notes, the Depositary shall be required to surrender any two
or more Global Notes which have identical terms, including, without limitation,
identical maturities, interest rates and redemption provisions (but which may
have differing Original Issue Dates) to the Trustee, and the Company shall
execute and the Trustee shall authenticate and deliver to, or at the direction
of, the Depositary a Global Note in principal amount equal to the aggregate
principal amount of, and with all terms identical to, the Global Notes
surrendered thereto and that shall indicate each applicable Original Issue Date
and the principal amount applicable to each such Original Issue Date. The
exchange contemplated in this subsection shall be consummated at least 30 days

surrendered to the Trustee. Upon any exchange of any Global Note with two or
more Original Issue Dates, whether pursuant to this Section or pursuant to
Section 2.06 or Section 3.03 hereof, the aggregate principal amount of the Notes
with a particular Original Issue Date shall be the same before and after such
exchange, after giving effect to any retirement of Notes and the Original Issue
Dates applicable to such Notes occurring in connection with such exchange.

either case to the effect that the Holders of the Notes will not recognize
income, gain or loss for federal income tax purposes as a result of such
defeasance or discharge of the Indenture and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case absent such defeasance or discharge of this
Indenture,

and if, in any such case, (x) the Company shall also pay or cause to be paid all
other sums payable hereunder by the Company and (y) the Company has delivered to
the Trustee an Officers' Certificate and an Opinion of Counsel each stating that
all conditions precedent herein provided for relating to the satisfaction and
discharge of this Indenture have been complied with, then this Indenture shall
cease to be of further effect (except as to (i) rights of registration of
transfer and exchange of Notes, (ii) substitution of mutilated, defaced,
destroyed, lost or stolen

Notes, (iii) rights of Noteholders to receive payments of principal thereof, and
any premium and interest thereon, upon the original stated due dates therefor or

the Company shall be deemed to have paid and discharged the entire indebtedness
represented by, and its obligations under, the Notes, and the Trustee, on demand
of the Company and at the cost and expense of the Company, shall execute proper
instruments acknowledging such satisfaction of and discharging this Indenture
and the Trustee shall at the request of the Company return to the Company all
Senior Note First Mortgage Bonds and all other property and money held by it
under this Indenture and determined by it from time to time in accordance with
the certification pursuant to this Section 5.01(a)(3) to be in excess of the
amount required to be held under this Section.

If the Notes are deemed to be paid and discharged pursuant to Section
5.01(a)(3) hereof, within 15 days after those Notes are so deemed to be paid and

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 9.06 hereof shall
survive.

If the Notes are deemed paid and discharged pursuant to this Section 5.01,
the obligation of the Company to make payment with respect to the principal of
and premium, if any, and interest on the Senior Note First Mortgage Bonds shall
be satisfied and discharged and the Senior Note First Mortgage Bonds shall cease
to secure the Notes in any manner.

ceasing to be entitled to any lien, benefit or security under this Indenture,

premium, if any, and interest on a principal amount of the Related Series of
Senior Note First Mortgage Bonds equal to the principal amount of such Note

Company if acting as its own paying agent), to the Holders of the particular
Notes for the payment or redemption of which such moneys and U.S. Government
Obligations have been deposited with the Trustee of all sums due and to become
due thereon for principal and premium, if any, and interest.

paid to the Trustee for payment of the principal of or any premium or interest
on any Notes and not applied but remaining unclaimed by the Holders of such
Notes for two years after the date upon which the principal of or any premium or
interest on such Notes, as the case may be, shall have become due and payable,

so secured); PROVIDED, HOWEVER, that the foregoing restriction shall not apply

development, pollution control or similar revenue bonds) incurred for the
purpose of financing all or any part of the purchase price or the cost of
constructing, developing, or substantially repairing, altering, or improving
Operating Property of the Company;

renewals, or replacements), in whole or in part, of any Lien referred to in the
foregoing clauses (i) to (iv), inclusive; PROVIDED, HOWEVER, that the principal

at its expense, any instruments necessary to so equally and ratably secure the
outstanding Notes and deliver the same to the Trustee along with:

In the event that the Company shall hereafter secure outstanding Notes
equally and ratably with any other obligation or indebtedness pursuant to the
provisions of this Section 6.07, the Company will, upon the request of the
Trustee, enter into an indenture or agreement supplemental hereto and to take
such other action, if any, as the Trustee may reasonably request to enable it to

of such Sale and Lease-Back Transaction, of Notes (in accordance with their
terms) or other Debt of the Company ranking senior to, or equally with, the
Notes; PROVIDED, HOWEVER, that the amount to be applied to such retirement of
Debt shall be reduced by an amount equal to the principal amount, plus any
premium or fee paid in connection with any redemption in accordance with the
terms of Debt voluntarily retired by the Company within such one hundred eighty
(180) day period, excluding retirement pursuant to mandatory sinking fund or

of such petition or to the appointment or taking possession by a receiver,
liquidator, assignee, custodian, trustee or sequestrator (or similar
official) of the Company or for any substantial part of the property of the
Company, or make any general assignment for the benefit of creditors, or
the notice by it in writing of its inability to pay its debts generally as
they become due, or the taking of any corporate action by the Company in
furtherance of any such action;

then, unless the principal of and interest on all of the Notes shall have
already become due and payable, either the Trustee or the Holders of a majority
in aggregate principal amount of the Notes then outstanding, by notice in
writing to the Company (and to the Trustee if given by such Holders), may
declare the principal of and interest on all the Notes to be due and payable
immediately and upon any such declaration the same shall become immediately due
and payable, anything in this Indenture or in the Notes contained to the
contrary notwithstanding and, upon the Notes being declared to be due and
payable, the Trustee shall immediately file with the Mortgage Trustee a written
demand for redemption of all Senior Note First Mortgage Bonds to the extent
provided in the applicable provisions of the supplemental indentures to the
First Mortgage.

The foregoing paragraph, however, is subject to the condition that if, at
any time after the principal of and interest on the Notes 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, and
prior to the acceleration of all of the First Mortgage Bonds issued and
outstanding under the First Mortgage, the Company shall pay or shall deposit
with the Trustee a sum sufficient to pay all matured installments of interest
upon all of the Notes and the principal of and any premium on any and all Notes
which shall have become due otherwise than by acceleration (with interest on
overdue installments of interest, to the extent that payment of such interest is
enforceable under applicable law, and on such principal and applicable premium
at the rate borne by the Notes to the date of such payment or deposit) and all
sums paid or advanced by the Trustee hereunder, the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under

Section 9.06 hereof, and any and all defaults under this Indenture, other than
the non-payment of principal of and accrued interest on Notes which shall have
become due solely by acceleration of maturity, shall have been cured or waived
(including any defaults under the First Mortgage, as evidenced by notice thereof
from the Mortgage Trustee to the Trustee), then and in every such case such
payment or deposit shall cause an automatic waiver of the Event of Default and
its consequences (including, if given, the written demand for redemption of all
Senior Note First Mortgage Bonds) and shall cause an automatic rescission and
annulment of the acceleration of the Notes; but no such waiver or rescission and
annulment shall extend to or shall affect any subsequent default, or shall
impair any right consequent thereon.

(b) If the Trustee shall have proceeded to enforce any right 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 the
Company and the Trustee shall be restored respectively to their several
positions and rights hereunder, and all rights, remedies and powers of the
Company and the Trustee shall continue as though no such proceeding had been
taken.

Section 8.02 COLLECTION OF INDEBTEDNESS BY TRUSTEE; TRUSTEE MAY PROVE
DEBT.

(a) The Company covenants that if an Event of Default described in
clause (a)(1) or (a)(2) of Section 8.01 hereof shall have occurred and be
continuing, then, upon demand of the Trustee, the Company shall pay to the
Trustee, for the benefit of the Holders of the Notes, the whole amount that then
shall have so become due and payable on all such Notes for principal or
interest, as the case may be, with interest upon the overdue principal and any
premium and (to the extent that payment of such interest is enforceable under
applicable law) upon the overdue installments of interest at the rate borne by
the Notes; and, in addition thereto, such further amounts as shall be sufficient
to cover the costs and expenses of collection, including reasonable compensation
to the Trustee, its agents, attorneys and counsel, any expenses or liabilities
incurred by the Trustee hereunder other than through its negligence or bad
faith. Until such demand is made by the Trustee, the Company may pay the
principal of and interest on the Notes to the Holders, whether or not the Notes
be overdue.

(b) In case the Company shall fail forthwith to pay such amounts upon
such demand, the Trustee, in its own name and as trustee of an express trust,
shall be entitled and empowered to institute any actions or proceedings at law
or in equity for the collection of the sums so due and unpaid, including, prior
to the Release Date, to exercise any rights to that end it may have as a holder
of Senior Note First Mortgage Bonds, and may enforce any such judgment or final
decree against the Company or any other obligor on the Notes and collect in the
manner provided by law out of the property of the Company or any other obligor
on such series of Notes wherever situated, the moneys adjudged or decreed to be
payable.

(c) In case there shall be pending proceedings relative to the
Company or any other obligor upon the Notes under Title 11 of the United States
Code or any other applicable Federal or state bankruptcy, insolvency or other
similar law, or in case a receiver, assignee or trustee in bankruptcy or
reorganization, liquidator, sequestrator or similar official shall have been
appointed for or taken possession of the Company or its property or such other
obligor, or in case of any other comparable judicial proceedings relative to the
Company or such other obligor,

or to the creditors or property of the Company or such other obligor, the
Trustee, irrespective of whether the principal of the Notes shall then be due
and payable as therein expressed or by declaration or otherwise and irrespective
of whether the Trustee shall have made any demand pursuant to the provisions of
this Section, shall be entitled and empowered, by intervention in such
proceedings or otherwise:

(1) to file and prove a claim or claims for the whole amount of
the principal and interest owing and unpaid in respect of the Notes, and to
file such other papers or documents as may be necessary or advisable in
order to have the claims of the Trustee (including, prior to the Release
Date, any claims of the Trustee as holder of Senior Note First Mortgage
Bonds and including any amounts due to the Trustee under Section 9.06
hereof) and of the Noteholders allowed in any judicial proceedings relative
to the Company or such other obligor, or to the creditors or property of
the Company or such other obligor; and

(2) to collect and receive any moneys or other property payable
or deliverable on any such claims, and to distribute all amounts received
with respect to the claims of the Noteholders and of the Trustee on their
behalf; and any trustee, receiver, liquidator, custodian or other similar
official is hereby authorized by each of the Noteholders to make payments
to the Trustee, and, in the event that the Trustee shall consent to the
making of the payments directly to the Noteholders, to pay to Trustee such
amounts due pursuant to Section 9.06 hereof.

(d) Nothing herein contained shall be deemed to authorize the Trustee
to authorize or consent to or vote for or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Notes of any series or the rights of any Holder thereof, or to
authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding except to vote for the election of a trustee in bankruptcy or similar
person.

(e) All rights of action and of asserting claims under this
Indenture, or under any of the Notes may be prosecuted and enforced by the
Trustee without the possession of any of the Notes or the production thereof at
any trial or other proceedings relative thereto, and any such action or
proceedings instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment, subject to the
payment of the expenses, disbursements and compensation of the Trustee and its
agents, attorneys and counsel, shall be for the ratable benefit of the Holders
of the Notes in respect of which such action was taken.

(f) In any proceedings brought by the Trustee (and also any
proceedings involving the interpretation of any provision of this Indenture to
which the Trustee shall be a party), the Trustee shall be held to represent all
the Holders of the Notes in respect to which action was taken, and it shall not
be necessary to make any Holders of such Notes parties to any such proceedings.

Section 8.03 APPLICATION OF PROCEEDS. Any moneys collected by the
Trustee with respect to any of the Notes pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee for
the distribution of such moneys, upon presentation of the

several Notes, and stamping thereon the payment, if only partially paid, and
upon surrender thereof if fully paid.

FIRST: To the payment of all amounts due to the Trustee pursuant to Section
9.06 hereof;

SECOND: In case the principal of the outstanding Notes in respect of which
such moneys have been collected shall not have become due and be unpaid, to the
payment of interest on the Notes, in the order of the maturity of the
installments of such interest, with interest (to the extent allowed by law) upon
the overdue installments of interest at the rate borne by the Notes, such
payments to be made ratably to the persons entitled thereto, and then to the
payment to the Holders entitled thereto of the unpaid principal of and
applicable premium on any of the Notes which shall have become due (other than
Notes previously called for redemption for the payment of which moneys are held
pursuant to the provisions of this Indenture), whether at stated maturity or by
redemption, in the order of their due dates, beginning with the earliest due
date, and if the amount available is not sufficient to pay in full all Notes due
on any particular date, then to the payment thereof ratably, according to the
amounts of principal and applicable premium due on that date, to the Holders
entitled thereto, without any discrimination or privilege;

THIRD: In case the principal of the outstanding Notes in respect of which
such moneys have been collected shall have become due, by declaration or
otherwise, to the payment of the whole amount then owing and unpaid upon the
Notes for principal and any premium and interest thereon, with interest on the
overdue principal and any premium and (to the extent allowed by law) upon
overdue installments of interest at the rate borne by the Notes; and in case
such moneys shall be insufficient to pay in full the whole amount so due and
unpaid upon the Notes, then to the payment of such principal and any premium and
interest without preference or priority of principal and any premium over
interest, or of interest over principal and any premium or of any installment of
interest over any other installment of interest, or of any Note over any other
Note, ratably to the aggregate of such principal and any premium and accrued and
unpaid interest; and

FOURTH: To the payment of the remainder, if any, to the Company or its
successors or assigns, or to whomsoever may lawfully be entitled to the same, or
as a court of competent jurisdiction may determine.

Section 8.04 LIMITATIONS ON SUITS BY NOTEHOLDERS.

(a) No Holder of any Note shall have any right by virtue of 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 such Holder previously shall have given to the Trustee written
notice of an Event of Default with respect to such Note and of the continuance
thereof, as hereinabove provided, and unless also Noteholders of a majority in
aggregate principal amount of the Notes then outstanding affected by such Event
of Default shall have made written request upon the Trustee to institute such
action, suit or proceeding in its own name as Trustee hereunder and 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, and the
Trustee for 60 days after

its receipt of such notice, request and offer of indemnity, shall have neglected
or refused to institute any such action, suit or proceeding; it being understood
and intended, and being expressly covenanted by the taker and Holder of every
Note with every other taker and Holder and the Trustee, that no one or more
Holders of Notes shall have any right in any manner whatever by virtue or by
availing of any provision of this Indenture to affect, disturb or prejudice the
rights of any other Holder of Notes, 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 Notes. For the protection and enforcement of
the provisions of this Section, each and every Noteholder and the Trustee shall
be entitled to such relief as can be given either at law or in equity.

(b) Notwithstanding any other provision in this Indenture, however,
the rights of any Holder of any Note to receive payment of the principal of and
any premium and interest on such Note, on or after the respective due dates
expressed in such Note or on the applicable redemption date, or to institute
suit for the enforcement of any such payment on or after such respective dates
are absolute and unconditional, and shall not be impaired or affected without
the consent of such Holder.

Section 8.05 SUITS FOR ENFORCEMENT. In case an Event of Default has
occurred, has not been waived and is continuing, hereunder the Trustee may in
its discretion proceed to protect and enforce the rights vested in it by this
Indenture, including, prior to the Release Date, its rights as holder of the
Senior Note First Mortgage Bonds, by such appropriate judicial proceedings as
the Trustee shall deem most effectual to protect and enforce any of such rights,
either by suit in equity or by action at law or by proceeding in bankruptcy or
otherwise, whether for the specific enforcement of any covenant or agreement
contained in this Indenture or in aid of the exercise of any power granted to it
under this Indenture, or to enforce any other legal or equitable right vested in
the Trustee by this Indenture or by law.

Section 8.06 POWERS AND REMEDIES CUMULATIVE; DELAY OR OMISSION NOT WAIVER
OF DEFAULT. No right or remedy herein conferred upon or reserved to the Trustee
or to the Holders of Notes is intended to be exclusive of any other right or
remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise. The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

No delay or omission of the Trustee or of any Holder of Notes 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 Event of Default or an acquiescence therein; and, subject to
Section 8.04, every right and power given by this Indenture or by law to the
Trustee or to the Holders of Notes may be exercised from time to time, and as
often as shall be deemed expedient, by the Trustee or by the Holders of Notes,
as the case may be.

Section 8.07 DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY
OF NOTEHOLDERS.

(a) The Holders of a majority in aggregate principal amount of the
Notes at the time outstanding 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; PROVIDED, that such
direction shall not be otherwise than in accordance with law and the provisions
of this Indenture; and PROVIDED FURTHER that (subject to Section 9.01 hereof)
the Trustee shall have the right to decline to follow any such direction if the
Trustee being advised by counsel determines that the action or proceeding so
directed may not lawfully be taken or if the Trustee in good faith by its board
of directors or trustees, executive committee, or a trust committee of directors
or trustees or responsible officers shall determine that the action or
proceeding so directed would involve the Trustee in personal liability. Nothing
in this Indenture shall impair the right of the Trustee in its discretion to
take any action deemed proper by the Trustee and which is not inconsistent with
such direction or directions by Noteholders.

(b) The Holders of a majority in aggregate principal amount of the
Notes at the time outstanding may on behalf of all of the Holders of the Notes
waive any past default or Event of Default hereunder and its consequences except
a default in the payment of principal of or any premium or interest on the
Notes. Upon any such waiver the Company, the Trustee and the Holders of the
Notes shall be restored to their former positions and rights hereunder,
respectively, but no such waiver shall extend to any subsequent or other default
or Event of Default or impair any right consequent thereon. Upon any such
waiver, such default shall cease to exist and be deemed to have been cured and
not to be continuing, and any Event of Default arising therefrom shall be deemed
to have been cured and not to be continuing, for every purpose of this
Indenture; but no such waiver shall extend to any subsequent or other default or
Event of Default or impair any right consequent thereon.

Section 8.08 NOTICE OF DEFAULT. The Trustee shall, within 90 days after
the occurrence of a default with respect to the Notes, give to all Holders of
the Notes, in the manner provided in Section 15.10, notice of such default known
to the Trustee, unless such default shall have been cured or waived before the
giving of such notice, the term "default" for the purpose of this Section 8.08
being hereby defined to be any event which is or after notice or lapse of time
or both would become an Event of Default; PROVIDED that, except in the case of
default in the payment of the principal of or any premium or interest on any of
the Notes, or in the payment of any sinking or purchase fund installments, the
Trustee shall be protected in withholding such notice if and so long as its
board of directors or trustees, executive committee, or a trust committee of
directors or trustees or responsible officers in good faith determines that the
withholding of such notice is in the interests of the Holders of the Notes.

Section 8.09 UNDERTAKING TO PAY COSTS. All parties to this Indenture
agree, and each Holder of any Note by 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, suffered 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 this Section 8.09 shall not
apply to any suit instituted by the Trustee, or to any suit instituted by any
Noteholder, or group of Noteholders, holding in the aggregate more than 10% in
principal amount of the Notes outstanding, or to any suit instituted by any
Noteholder for the enforcement of the payment of the principal of or any premium
or interest on any Note on or after the due date expressed in such Note or the
applicable redemption date.

Section 8.10 RESTORATION OF RIGHTS ON ABANDONMENT OF PROCEEDINGS. In
case the Trustee or any Holder shall have proceeded to enforce any right under
this Indenture and such proceedings shall have been discontinued or abandoned
for any reason, or shall have been determined adversely to the Trustee or to
such Holder, then, and in every such case, the Company, the Trustee and the
Holders shall be restored respectively to their former positions and rights
hereunder, and all rights, remedies and powers of the Company, the Trustee and
the Holders shall continue as though no such proceedings had been taken.

Section 8.11 DEFAULTS UNDER THE FIRST MORTGAGE. In addition to every
other right and remedy provided herein, the Trustee may exercise any right or
remedy available to the Trustee in its capacity as owner and holder of Senior
Note First Mortgage Bonds which arises as a result of a default under the First
Mortgage whether or not an Event of Default under this Indenture shall then have
occurred and be continuing.

Section 8.12 WAIVER OF USURY, STAY OR EXTENSION LAWS. The Company
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

perform such duties and only such duties as are specifically set forth in this
Indenture. If an Event of Default has occurred (which has not been cured or
waived), the Trustee shall exercise such of the rights and powers vested in it
by this Indenture, and use the same degree of care and skill in their exercise,
as a prudent man would exercise or use under the circumstances in the conduct of
his own affairs.

(b) No provisions 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:

(1) prior to the occurrence of any Event of Default and after
the curing or waiving of all Events of Default which may have occurred

(A) the duties and obligations of the Trustee shall be
determined solely by the express provisions of this Indenture, and the
Trustee shall not be liable 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 or actual knowledge on the part
of the Trustee, the Trustee may 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 which by any provision hereof are specifically required to be
furnished to the Trustee, the Trustee shall be under a duty to examine the
same to determine whether or not they conform to the requirements of this
Indenture;

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

(3) 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, pursuant to this Indenture, of the Holders of a majority in

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

Counsel shall be full and complete authorization and protection in respect of
any action taken, suffered or omitted by it hereunder in good faith and in
accordance with such advice or Opinion of Counsel;

(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 Noteholders,

pursuant to this Indenture, unless such Noteholders shall have offered to the
Trustee reasonable security or indemnity against the costs, expenses and
liabilities which may be incurred by such exercise;

(e) the Trustee shall not be liable for any action taken, suffered or
omitted 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) prior to the occurrence of an Event of Default hereunder and
after the curing or waiving of all Events of Default, 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, note or other paper or document, unless
requested in writing to do so by the Holders of at least a majority in principal
amount of the then outstanding Notes; PROVIDED 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
this Indenture, the Trustee may require reasonable indemnity against such
expense or liability as a condition to so proceeding;

(g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or through agents or attorneys;
PROVIDED that the Trustee shall not be liable for the conduct or acts of any
such agent or attorney that shall have been appointed in accordance herewith
with due care.

Section 9.03 NO RESPONSIBILITY FOR RECITALS, ETC. The recitals contained
herein and in the Notes (except in the certificate of authentication) shall be
taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Notes. The Trustee shall not be accountable for the use or application by the
Company of any Notes or the proceeds of any Notes authenticated and delivered by
the Trustee in conformity with this Indenture.

Section 9.04 TRUSTEE, AUTHENTICATING AGENT, PAYING AGENT OR REGISTRAR MAY

individual or other capacity, may become the owner or pledgee of Notes with the
same rights it would have if it were not Trustee, Authenticating Agent or paying
agent.

Section 9.05 MONEYS TO BE HELD IN TRUST. Subject to Section 5.04 hereof,
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 may allow and credit to the Company interest on any money received
hereunder at such rate, if any, as may be agreed upon by the Company and the
Trustee from time to time as may be permitted by law.

Section 9.06 COMPENSATION AND EXPENSES OF TRUSTEE. The Company covenants
and agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, reasonable compensation (which shall not be limited by any law in
regard to the compensation of a trustee

of an express trust), and the Company shall pay or reimburse the Trustee upon
its request for all reasonable expenses, disbursements and advances incurred or
made by the Trustee in accordance with this Indenture (including the reasonable
compensation and the reasonable expenses and disbursements of its counsel and
agents, including any Authenticating Agents, 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. The Company also covenants to indemnify the Trustee
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
costs and expenses of defending itself against any claim or liability. The
obligations of the Company under this Section 9.06 to compensate the Trustee and
to pay or reimburse the Trustee for expenses, disbursements and advances shall
constitute additional indebtedness hereunder. Such additional indebtedness shall
be secured by a lien prior to that of the Notes 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 any particular Notes.

Section 9.07 OFFICERS' CERTIFICATE AS EVIDENCE. Whenever in the
administration of this Indenture, the Trustee shall deem it necessary or
desirable that a matter be proved or established prior to the taking, suffering
or omitting of any action hereunder, such matter (unless other evidence in
respect thereof is 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 Officers' Certificate delivered to the Trustee, and
such Officers' 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 by it under this Indenture in reliance thereon.

Section 9.08 CONFLICTING INTEREST OF TRUSTEE. The Trustee shall be
subject to and shall comply with the provisions of Section 310(b) of the TIA.
Nothing in this Indenture shall be deemed to prohibit the Trustee or the Company
from making any application permitted pursuant to such section.

Section 9.09 EXISTENCE AND ELIGIBILITY OF TRUSTEE. There shall at all
times be a Trustee hereunder which Trustee shall at all times be a corporation
organized and doing business under the laws of the United States or any State
thereof or of the District of Columbia having a combined capital and surplus of
at least $250,000,000 and which is authorized under such laws to exercise
corporate trust powers and is subject to supervision or examination by Federal
or State authorities. Such corporation shall have its principal place of
business in the City of St. Louis, Missouri or the Borough of Manhattan, The
City of New York, State of New York, if there be such a corporation in such
location willing to act upon reasonable and customary terms and conditions. If
such corporation publishes reports of condition at least annually, pursuant to
law or to the requirements of the aforesaid authority, then for the purposes of
this Section 9.09, the combined capital and surplus shall be deemed to be as set
forth in its most recent report of condition so published. No obligor upon the
Notes or Person directly or indirectly controlling, controlled by, or under
common control with such obligor shall serve as Trustee. If at any time the
Trustee shall cease to be eligible in accordance with this Section 9.09, the
Trustee shall resign immediately in the manner and with the effect specified in
Section 9.10 hereof.

Section 9.10 RESIGNATION OR REMOVAL OF TRUSTEE.

(a) Pursuant to the provisions of this Article, the Trustee may at
any time resign and be discharged of the trusts created by this Indenture by
giving written notice to the Company specifying the day upon which such
resignation shall take effect, and such resignation shall take effect
immediately upon the later of the appointment of a successor trustee and such
day.

(b) Any Trustee may be removed at any time by an instrument or
concurrent instruments in writing filed with such Trustee and signed and
acknowledged by the Holders of a majority in principal amount of the then
outstanding Notes or by their attorneys in fact duly authorized.

(c) So long as no Event of Default has occurred and is continuing,
and no event has occurred and is continuing that, with the giving of notice or
the lapse of time or both, would become an Event of Default, the Company may
remove any Trustee upon written notice to the Holder of each Note outstanding
and the Trustee and appoint a successor Trustee meeting the requirements of
Section 9.09. The Company or the successor Trustee shall give notice to the
Holders, in the manner provided in Section 15.10, of such removal and
appointment within 30 days of such removal and appointment.

(d) If at any time (i) the Trustee shall cease to be eligible in
accordance with Section 9.09 hereof and shall fail to resign after written
request therefor by the Company or by any Holder who has been a bona fide Holder
for at least six months, (ii) the Trustee shall fail to comply with Section 9.08
hereof after written request therefor by the Company or any such Holder, or
(iii) the Trustee shall become incapable of acting or shall be adjudged a
bankrupt or insolvent or a receiver of the Trustee or its property shall be
appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation, then the Trustee may be removed forthwith by an instrument or

corporation.

CONCERNING THE NOTEHOLDERS

Section 10.01 ACTION BY NOTEHOLDERS. Whenever in this Indenture it is
provided that the Holders of a specified percentage in aggregate principal
amount of the Notes may take any action, the fact that at the time of taking any
such action the Holders of such specified percentage have joined therein may be
evidenced (a) by any instrument or any number of instruments of similar tenor
executed by such Noteholders in person or by agent or proxy appointed in
writing, (b) by the record of such Noteholders voting in favor thereof at any
meeting of Noteholders duly called and held in accordance with Article XI
hereof, or (c) by a combination of such instrument or instruments and any such
record of such a meeting of Noteholders.

Section 10.02 PROOF OF EXECUTION BY NOTEHOLDERS.

(a) Subject to Sections 9.01, 9.02 and 11.05 hereof, proof of the
execution of any instruments by a Noteholder or the agent or proxy for such
Noteholder shall be sufficient if made in accordance with such reasonable rules
and regulations as may be prescribed by the Trustee or in such manner as shall
be satisfactory to the Trustee. The ownership of Notes shall be proved by the
register for the Notes maintained by the Trustee.

(b) The record of any Noteholders' meeting shall be proven in the
manner provided in Section 11.06 hereof.

Section 10.03 PERSONS DEEMED ABSOLUTE OWNERS. Subject to Sections 2.04(f)
and 10.01 hereof, the Company, the Trustee, any paying agent and any
Authenticating Agent shall deem the person in whose name any Note shall be
registered upon the register for the Notes to be, and shall treat such person
as, the absolute owner of such Note (whether or not such Note shall be overdue)
for the purpose of receiving payment of or on account of the principal and
premium, if any, and interest on such Note, and for all other purposes; and
neither the Company nor the Trustee nor any paying agent nor any Authenticating
Agent shall be affected by any notice to the contrary. All such payments shall
be valid and effectual to satisfy and discharge the liability upon any such Note
to the extent of the sum or sums so paid.

Section 10.04 COMPANY-OWNED NOTES DISREGARDED. In determining whether the
Holders of the requisite aggregate principal amount of outstanding Notes have
concurred in any direction, consent or waiver under this Indenture, Notes that
are owned by the Company or any other obligor on the Notes or by any person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any other obligor on the Notes shall be
disregarded and deemed not to be outstanding for the purpose of any such
determination; PROVIDED that, for the purposes of determining whether the
Trustee shall be protected in relying on any such direction, consent or waiver,
only Notes which the Trustee knows are so owned shall be so disregarded. Notes
so owned which have been pledged in good faith to third parties may be regarded
as outstanding for the purposes of this Section 10.04 if the pledgee shall
establish the pledgee's right to take action with respect to such Notes 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 the case of a dispute as to such
right, the Trustee may rely upon an Opinion of Counsel and an Officers'
Certificate to establish the foregoing.

Section 10.05 REVOCATION OF CONSENTS; FUTURE HOLDERS BOUND. Except as may
be otherwise required in the case of a Global Note by the applicable rules and
regulations of the Depositary, at any time prior to the taking of any action by
the Holders of the percentage in aggregate principal amount of the Notes
specified in this Indenture in connection with such action, any Holder of a
Note, which has been included in the Notes the Holders of which have consented
to such action may, by filing written notice with the Trustee at the corporate
trust office of the Trustee and upon proof of ownership as provided in Section
10.02(a) hereof, revoke such action so far as it concerns such Note. Except as
aforesaid, any such action taken by the Holder of any Note shall be conclusive
and binding upon such Holder and upon all future Holders and owners of such Note
and of any Notes issued in exchange, substitution or upon registration of
transfer therefor, irrespective of whether or not any notation thereof is made
upon such Note or such other Notes.

Section 10.06 RECORD DATE FOR NOTEHOLDER ACTS. If the Company shall
solicit from the Noteholders any request, demand, authorization, direction,
notice, consent, waiver or other act, the Company may, at its option, by Board
Resolution, fix in advance a record date for the determination of Noteholders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other act, but the Company shall have no obligation to do so.
If such a record date is fixed, such request, demand, authorization, direction,
notice, consent, waiver or other act may be given before or after the record
date, but only the Noteholders of record at the close of business on the record
date shall be deemed to be Noteholders for the purpose of determining whether
Holders of the requisite aggregate principal amount of outstanding Notes have
authorized or agreed or consented to such request, demand, authorization,
direction, notice, consent, waiver or other act, and for that purpose the
outstanding Notes shall be computed as of the record date; PROVIDED that no such
request, demand, authorization, direction, notice, consent, waiver or other act
by the Noteholders on the record date shall be deemed effective unless it shall
become effective pursuant to this Indenture not later than six months after the
record date. Any such record date shall be at least 30 days prior to the date of
the solicitation to the Noteholders by the Company.

conditions precedent have been complied with.

(b) Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
provided for in this Indenture (other than the certificates delivered pursuant
to Section 6.06 hereof) shall include (1) a statement that each Person making

Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which such certificate or opinion is based are
erroneous. Any such certificate or opinion of counsel delivered under the
Indenture may be based, insofar as it relates to factual matters, upon a
certificate or opinion of, or representations by, an officer or officers of the
Company stating that the information with respect to such factual matters is in

Section 2.05(c) hereof, in any case where the date of Maturity of the principal
of or any premium or interest on any Note or the date fixed for redemption of
any Note is not a Business Day, then payment of

such principal or any premium or interest need not be made on such date but may
be made on the next succeeding Business Day with the same force and effect as if

on the Holders of Notes, as the case may be, shall be given or served by
first-class mail, postage prepaid, addressed to the Holders of such Notes at

Holder by mail, then such notification to such Holder as shall be made with the
approval of the Trustee shall constitute a sufficient notification for every
purpose hereunder.

any Global Notes representing such Notes) of the Company issued and to be issued
under an Indenture dated as of December 1, 1998, between the Company and The
Bank of New York, as trustee (the "TRUSTEE", which term includes any successor
Trustee under the Indenture) and indentures supplemental thereto (collectively,
the "INDENTURE"). Under the Indenture, one or more series of notes may be issued
and, as used herein, the term "Notes" refers to the Notes of this Series and any
other outstanding series of Notes. Reference is hereby made to the Indenture for
a more complete statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee and the Noteholders
and of the terms upon which the Notes are and are to be authenticated and
delivered. This Global Note has been issued in respect of the series designated

the holders of first mortgage bonds, under the First Mortgage and the rights of

the aggregate principal amount of a series of Senior Note First Mortgage Bonds
held by the Trustee, but in no event prior to the Release Date to amount less

Original Issue Date of such transferred, exchanged or substituted Note, as the

basis of a 360-day year of twelve 30-day months (and for any partial periods

principal of this Global Note is required to be paid is not a Business Day, then
payment of principal, premium or interest need not be made on such date but may
be made on the next succeeding Business Day with the same force and effect as if

provided in the Indenture, will be discharged from any and all obligations in
respect of the Notes (except for certain obligations including obligations to
register the transfer or exchange of Notes, replace stolen, lost or mutilated
Notes, maintain paying agencies and hold monies for payment in trust, all as set
forth in the Indenture) if the Company deposits with the Trustee money, U.S.
Government Obligations which through the payment of interest thereon and
principal thereof in accordance with their terms will provide money, or a
combination of money and U.S. Government Obligations, in any event in an amount
sufficient, without reinvestment, to pay all the principal of and any premium
and interest on the Notes on the dates such payments are due in accordance with
the terms of the Notes.

If an Event of Default shall occur and be continuing, the principal of and
interest on the Notes may be declared due and payable in the manner and with the
effect provided in the Indenture and, upon such declaration, the Trustee shall
demand the redemption of the Senior Note First Mortgage Bonds to the extent

Notes. Any such consent or waiver by the Holder of this Global Note shall be

Global Note and of any Note issued upon the registration of transfer hereof or
in exchange therefor or in lieu thereof whether or not notation of such consent
or waiver is made upon the Note.

As set forth in and subject to the provisions of the Indenture, no Holder
of any Notes will have any right to institute any proceeding with respect to the
Indenture or for any remedy thereunder unless such Holder shall have previously
given to the Trustee written notice of a continuing Event of Default with
respect to such Notes, the Holders of not less than a majority in principal
amount of the outstanding Notes affected by such Event of Default shall have
made written request and offered reasonable indemnity to the Trustee to
institute such proceeding as Trustee and the Trustee shall have failed to
institute such proceeding within 60 days; provided that such limitations do not
apply to a suit instituted by the Holder hereof for the enforcement of payment
of the principal of and any premium or interest on this Note on or after the
respective due dates expressed here.

No reference herein to the Indenture and to provisions of this Global Note
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of and any premium and
interest on this Global Note at the times, places and rates and the coin or
currency prescribed in the Indenture.

As provided in the Indenture and subject to certain limitations therein set
forth, this Global Note may be transferred only as permitted by the legend
hereto and the provisions of the Indenture.

The Indenture and the Notes shall be governed by, and construed in
accordance with, the laws of the State of New York.

Trustee, directly or through an Authenticating Agent by manual signature of an
authorized officer, this Global Note shall not be entitled to any benefit under
the Indenture or be valid or obligatory for any purpose.

All terms used in this Global Note which are defined in the Indenture shall
