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

Securities of any particular series may be issued at various times, with
different dates on which the principal or any installment of principal is
payable, with different rates of interest, if any, or different methods by which
rates of interest may be determined, with different dates on which such interest
may be payable and with different redemption dates.

SECTION 2.02 Form of Securities and Trustee's Certificate.

The Securities of any series and the Trustee's certificate of authentication to
be borne by such Securities shall be substantially of the tenor and purport as
set forth in one or more indentures supplemental hereto or as provided in a
Board Resolution of the Company and as set forth in an Officers' Certificate of
the Company and the and may have such letters, numbers or other marks of
identification or designation and such legends or endorsements printed,
lithographed or engraved thereon as the Company may deem appropriate and as are
not inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock exchange on which Securities of that series
may be listed, or to conform to usage.

SECTION 2.03 Denominations: Provisions for Payment.

The Securities shall be issuable as registered Securities and in the
denominations of one thousand U.S. dollars ($1,000) or any integral multiple
thereof, subject to Section 2.01(10). The Securities of a particular series
shall bear interest payable on the dates and at the rate specified with respect
to that series. The principal of and the interest on the Securities of any
series, as well as any premium thereon in case of redemption thereof prior to
maturity, shall be payable in the coin or currency of the United States of
America that at the time is legal tender for public and private debt, at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, the City and State of New York. Each Security shall be dated the date
of its authentication. Interest on the Securities shall be computed on the basis
of a 360-day year composed of twelve 30-day months.

The interest installment on any Security that is payable, and is punctually paid
or duly provided for, on any Interest Payment Date for Securities of that series
shall be paid to the Person in whose name said Security (or one or more
Predecessor Securities) is registered at the close of business on the regular
record date for such interest installment. In the event that any Security of a
particular series or portion thereof is called for redemption and the redemption
date is subsequent to a regular record date with respect to any Interest Payment
Date and prior to such Interest Payment Date, interest on such Security will be
paid upon presentation and surrender of such Security as provided in Section
3.03.

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

                                       7
<PAGE>

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 of the Company 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 with respect to 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 last 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 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.

SECTION 2.04 Execution and Authentications.

The Securities shall be signed on behalf of the Company by its President, or one
of its Vice Presidents, or its Treasurer, or one of its Assistant Treasurers, or
its Secretary, or one of its Assistant Secretaries, under its corporate seal
attested by its Secretary or one of its Assistant Secretaries. 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 a President or Vice
President thereof, or of any Person who shall have been a Secretary or Assistant
Secretary thereof,

                                       8
<PAGE>

notwithstanding the fact that at the time the Securities shall be authenticated
and delivered or disposed of such Person shall have ceased to be the President
or a Vice President, or the Secretary or an Assistant Secretary, of the Company.
The seal of the Company may be in the form of a facsimile of such seal and may
be impressed, affixed, imprinted or otherwise reproduced on the Securities. 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 its President or any Vice President and its Secretary or
any Assistant Secretary, 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.

         (a)  Securities of any series may be exchanged upon presentation
thereof at the office or agency of the Company designated for such purpose in
the Borough of Manhattan, the City and State of New York, 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 in the Borough of Manhattan, the City and
State of New York, or such other location designated by the Company 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

                                       9
<PAGE>

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)   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. The provisions of this Section 2.05 are, with respect to any Global
Security, subject to Section 2.11 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 in the Borough of Manhattan, the City and State of
New York, 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

                                       10
<PAGE>

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

                                       11
<PAGE>

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)

                                       12
<PAGE>

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, this Section 2.11 shall
no longer be applicable to the Securities of such series and the Company will
execute, and subject to Section 2.05, 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
2.05, the Trustee, upon receipt of an Officers' 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.

                                   ARTICLE III

              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.

                                       13
<PAGE>

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 the right reserved so to do, 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 Officers' 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 in the Borough of
Manhattan, the City and State of New York, 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 for 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 whole or 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.

         (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 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 its President or any Vice President, 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

                                       14
<PAGE>

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 (other than any
Securities previously called for redemption) 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

                                       15

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, the Company will deliver to the Trustee an Officers' 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
Officers' 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.

SECTION 4.01 Payment of Principal, Premium and Interest.

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.

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 in the Borough of Manhattan, the City and State
of New York, 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 its President or a Vice President 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.

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

                  (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 (an
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 any paying
agent to the Trustee, such paying agent shall be released from all further
liability with respect to such money.

Trustee, will appoint, in the manner provided in Section 7.10, a Trustee, so
that there shall at all times be a Trustee hereunder.

SECTION 4.05 Compliance with Consolidation Provisions.

The Company will not, while any of the Securities remain Outstanding,
consolidate with or merge into any other Person, in either case where the
Company is not the survivor of such transaction, or sell or convey all or
substantially all of its property to any other company unless the provisions of
Article Ten hereof are complied with.

         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 continuance of such default 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;

                (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, 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

                                       20
<PAGE>

declare the principal of 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.

         (c)    At any time after the principal of 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
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 (1) in case it shall default in the
payment of any installment of interest on any of the Securities of a series, or
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 Business Days, or (2) 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,

                                       21
<PAGE>

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 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 affected 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,

                                       22
<PAGE>

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 the payment,
if only partially paid, and upon surrender thereof if fully paid:

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

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

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;
and (iv) the Trustee for 60 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 60 day period, the holders of a majority in
principal amount of the Securities of that series do not give the Trustee a
direction inconsistent with the request.

Notwithstanding anything contained herein to the contrary, 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

                                       23
<PAGE>

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 on 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 8.01,
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 be unduly prejudicial to the rights of holders of Securities of any
other series at the time Outstanding determined in accordance with Section 8.01.
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 would involve the Trustee in personal liability. 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 8.01,
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

                                       24
<PAGE>

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:

               (1)  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:

                                       25
<PAGE>

                   (i) 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

                   (ii) 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 requirement of this
Indenture;

             (2)   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;

             (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 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

             (4)   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 the President or any Vice President and by
the Secretary or an Assistant Secretary or the Treasurer or an Assistant
Treasurer thereof (unless other evidence in respect thereof is specifically
prescribed herein);

                                       26
<PAGE>

         (c) The Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken 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;

         (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; and

         (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.

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.

                                       27
<PAGE>

         (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. 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 costs and expenses of defending itself against any claim of
liability in the premises.

         (b) The obligations of the Company under this Section to compensate and
indemnify 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
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.

                                       28
<PAGE>

SECTION 7.07 Reliance on Officers' Certificate.

Except as otherwise provided in Section 7.01, whenever in the administration of
the provisions of this Indenture the Trustee shall deem it 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 Officers' 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 50
million U.S. dollars ($50,000,000), and subject to supervision or examination by
Federal, State, Territorial, or District of Columbia authority. If such
corporation 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 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

                                       29
<PAGE>

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:

               (1)   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

               (2)   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

               (3)   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, 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, unless the Trustee's duty to resign is stayed as provided
herein, 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.

                                       30
<PAGE>

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.

         (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 (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor trustee relates, (2)
shall contain such provisions as shall be deemed necessary or desirable to
confirm that all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust, 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

                                       31
<PAGE>

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, 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.

                                  ARTICLE VIII

                         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.

                                       32
<PAGE>

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 Officers' 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.

SECTION 8.02 Proof of Execution by Securityholders.

Subject 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.

         (c)   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.

                                       33
<PAGE>

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 of
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.

SECTION 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.

                                   ARTICLE IX

                             SUPPLEMENTAL INDENTURES

SECTION 9.01 Supplemental Indentures Without the Consent of Securityholders.

In addition to any supplemental indenture otherwise authorized by this
Indenture, the Company and the Trustee may from time to time and at any time
enter into an indenture or indentures supplemental hereto (which shall conform
to the provisions of the Trust Indenture Act as then in effect), without the
consent of the Securityholders, for one or more of the following purposes:

                                       34
<PAGE>

         (a)   to cure any ambiguity, defect, or inconsistency herein, in the
Securities of any series;

         (b)   to comply with Article Ten;

         (c)   to provide for uncertificated Securities in addition to or in
place of certificated Securities;

         (d)   to add to the covenants of the Company for the benefit of the
holders of all or any Series of Securities (and if such covenants are to be for
the benefit of less than all series of Securities, stating that such covenants
are expressly being included solely for the benefit of such series) or to
surrender any right or power herein conferred upon the Company;

         (e)   to add to, delete from, or revise the conditions, limitations,
and restrictions on the authorized amount, terms, or purposes of issue,
authentication, and delivery of Securities, as herein set forth;

         (f)   to make any change that does not adversely affect the rights of
any Securityholder in any material respect; or

         (g)   to provide for the issuance of and establish the form and terms
and conditions of the Securities of any series as provided in Section 2.01, to
establish the form of any certifications required to be furnished pursuant to
the terms of this Indenture or any series of Securities, or to add to the rights
of the holders of any series of Securities.

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

Any supplemental indenture authorized by the provisions of this Section may be
executed by the Company and the Trustee without the consent of the holders of
any of the Securities at the time Outstanding, notwithstanding any of the
provisions of Section 9.02.

SECTION 9.02 Supplemental Indentures With Consent of Securityholders.

With the consent (evidenced as provided in Section 8.01) of the holders of not
less than a majority in aggregate principal amount of the Securities of each
series affected by such supplemental indenture or indentures at the time
Outstanding, the Company, when authorized by Board Resolutions, and the Trustee
may from time to time and at any time enter into an indenture or indentures
supplemental hereto (which shall conform to the provisions of the Trust
Indenture Act as then in effect) for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture or
of any supplemental indenture or of modifying in any manner not covered by
Section 9.01 the rights of the holders of the Securities of such series under
this Indenture; provided, however, that no such supplemental indenture

                                       35
<PAGE>

shall, without the consent of the holders of each Security then Outstanding and
affected thereby, (i) extend the fixed maturity of any Securities of any series,
or reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof or (ii) reduce the aforesaid percentage of Securities, the holders of
which are required to consent to any such supplemental indenture.

It shall not be necessary for the consent of the Securityholders of any series
affected thereby under this Section to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such consent
shall approve the substance thereof.

SECTION 9.03 Effect of Supplemental Indentures.

Upon the execution of any supplemental indenture pursuant to the provisions of
this Article or of Section 10.01, this Indenture shall, with respect to such
series, be and be deemed to be modified and amended in accordance therewith and
the respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Company and the holders of Securities
of the series affected thereby shall thereafter be determined, exercised and
enforced hereunder subject in all respects to such modifications and amendments,
and all the terms and conditions of any such supplemental indenture shall be and
be deemed to be part of the terms and conditions of this Indenture for any and
all purposes.

SECTION 9.04 Securities Affected by Supplemental Indentures.

Securities of any series affected by a supplemental indenture, authenticated and
delivered after the execution of such supplemental indenture pursuant to the
provisions of this Article or of Section 10.01, may bear a notation in form
approved by the Company, provided such form meets the requirements of any
exchange upon which such series may be listed, as to any matter provided for in
such supplemental indenture. If the Company shall so determine, new Securities
of that series so modified as to conform, in the opinion of the Board of
Directors of the Company, to any modification of this Indenture contained in any
such supplemental indenture may be prepared by the Company, authenticated by the
Trustee and delivered in exchange for the Securities of that series then
Outstanding.

SECTION 9.05 Execution of Supplemental Indentures.

Upon the request of the Company, accompanied by its Board Resolutions
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence of the consent of Securityholders required
to consent thereto as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion but shall not be
obligated to enter into such supplemental indenture. The Trustee, subject to the
provisions of Section 7.01, may receive an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article is
authorized or permitted by, and conforms to, the terms of this Article and that
it is proper for the Trustee under the provisions of this Article to join in the
execution thereof; provided, however, that such Opinion of Counsel need not be
provided in connection with the

                                       36
<PAGE>

execution of a supplemental indenture that establishes the terms of a series of
Securities pursuant to Section 2.01 hereof.

Promptly after the execution by the Company and the Trustee of any supplemental
indenture pursuant to the provisions of this Section, the Trustee shall transmit
by mail, first class postage prepaid, a notice, setting forth in general terms
the substance of such supplemental indenture, to the Securityholders of all
series affected thereby as their names and addresses appear upon the Security
Register. Any failure of the Trustee to mail such notice, or any defect therein,
shall not, however, in any way impair or affect the validity of any such
supplemental indenture.

SECTION 10.01 Company May Consolidate, Etc.

Nothing contained in this Indenture or in any of the Securities shall prevent
any consolidation or merger of the Company with or into any other Person

mergers in which the Company or its successor or successors shall be a party or
parties, or shall prevent any sale, conveyance, transfer or other disposition of
the property of the Company or its successor or successors as an entirety, or
substantially as an entirety, to any other corporation (whether or not
affiliated with the Company or its successor or successors) authorized to
acquire and operate the same; provided, however, the Company hereby covenants
and agrees that, upon any such consolidation or merger (in each case, if the
Company is not the survivor of such transaction), sale, conveyance, transfer or
other disposition, the due and punctual payment of the principal of (premium, if
any) and interest on all of the Securities of all series in accordance with the
terms of each series, according to their tenor and the due and punctual
performance and observance of all the covenants and conditions of this Indenture
with respect to each series or established with respect to such series pursuant
to Section 2.01 to be kept or performed by the Company shall be expressly
assumed, by supplemental indenture (which shall conform to the provisions of the
Trust Indenture Act, as then in effect) satisfactory in form to the Trustee
executed and delivered to the Trustee by the entity formed by such
consolidation, or into which the Company shall have been merged, or by the
entity which shall have acquired such property.

SECTION 10.02 Successor Entity Substituted.

         (a)  In case of any such consolidation, merger, sale, conveyance,
transfer or other disposition and upon the assumption by the successor entity by

premium, if any, and interest on all of the Securities of all series Outstanding
and the due and punctual performance of all of the covenants and conditions of
this Indenture or established with respect to each series of the Securities
pursuant to Section 2.01 to be performed by the Company with respect to each
series, such successor entity shall succeed to and be substituted for the
Company with the same effect as if it had been named as the Company herein, and
thereupon the predecessor corporation shall be relieved of all obligations and
covenants under this Indenture and the Securities.

                                       37

         (b)   In case of any such consolidation, merger, sale, conveyance,
transfer or other disposition such changes in phraseology and form (but not in
substance) may be made in the Securities thereafter to be issued as may be
appropriate.

         (c)   Nothing contained in this Article shall require any action by the
Company in the case of a consolidation or merger of any Person into the Company
where the Company is the survivor of such transaction, or the acquisition by the
Company, by purchase or otherwise, of all or any part of the property of any
other Person (whether or not affiliated with the Company).

SECTION 10.03 Evidence of Consolidation, Etc. to Trustee.

         The Trustee, subject to the provisions of Section 7.01, may receive an
Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance, transfer or other disposition, and any such assumption, comply
with the provisions of this Article.

delivered to the Trustee for cancellation, including principal (and premium, if
any) and interest due or to become due to such date of maturity or date fixed

Governmental Obligations sufficient to pay at maturity or upon redemption all
such Securities of that series not theretofore delivered to the Trustee for
cancellation, including principal (and premium, if any) and interest due or to
become due to such date of maturity or date fixed for redemption, as the case
may be, and if the Company shall also pay or cause to be paid all other sums
payable hereunder by the Company with respect to such series, then after the

provisions of Sections 2.03, 2.05, 2.07, 4,01, 4.02, 4,03, 7.06, 7.10 and 11.05

of Securities for the payment or redemption of which such moneys or Governmental
Obligations have been deposited with the Trustee.

In connection with the satisfaction and discharge of this Indenture all moneys

Trustee, or then held by the Company, in trust for payment of principal of or
premium or interest on the Securities of a particular series that are not

years after the date upon which the principal of (and premium, if any) or
interest on such Securities shall have respectively become due and payable,
shall be repaid to the Company on May 31 of each year or (if then held by the
Company) shall be discharged from such trust; and thereupon the paying agent and
the Trustee shall be released from all further liability with respect to such
moneys or Governmental Obligations, and the holder of any of the Securities
entitled to receive such payment shall thereafter, as an unsecured general
