denomination and except as may otherwise be provided in or pursuant to any such
Board Resolution or in any indentures supplemental hereto.

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

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

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

                                       7
<PAGE>

           Defaulted Interest, which shall be fixed in the following manner: the
           Company shall notify the Trustee in writing of the amount of
           Defaulted Interest proposed to be paid on each such Security and the
           date of the proposed payment, and at the same time the Company shall
           deposit with the Trustee an amount of money equal to the aggregate
           amount proposed to be paid in respect of such Defaulted Interest or
           shall make arrangements satisfactory to the Trustee for such deposit
           prior to the date of the proposed payment, such money when deposited
           to be held in trust for the benefit of the Persons entitled to such
           Defaulted Interest as in this clause provided. Thereupon the Trustee
           shall fix a special record date for the payment of such Defaulted
           Interest which shall not be more than 15 nor less than 10 days prior
           to the date of the proposed payment and not less than 10 days after
           the receipt by the Trustee of the notice of the proposed payment. The
           Trustee shall promptly notify the Company of such special record date
           and, in the name and at the expense of the Company, shall cause
           notice of the proposed payment of such Defaulted Interest and the
           special record date therefor to be mailed, first class postage
           prepaid, to each Securityholder at his or her address as it appears
           in the Security Register (as hereinafter defined), not less than 10
           days prior to such special record date. Notice of the proposed
           payment of such Defaulted Interest and the special record date
           therefor having been mailed as aforesaid, such Defaulted Interest
           shall be paid to the Persons in whose names such Securities (or their
           respective Predecessor Securities) are registered on such special
           record date.

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

Unless otherwise set forth in a Board Resolution 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.

                                       8
<PAGE>

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, 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.

                                       9
<PAGE>

        (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
        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

                                      10
<PAGE>

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 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.

                                      11
<PAGE>

SECTION 2.08  Cancellation.

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

SECTION 2.09  Benefits of Indenture.

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

SECTION 2.10  Authenticating Agent.

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

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

SECTION 2.11  Global Securities.

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

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

     (c)  If at any time the Depositary for a series of the Securities notifies
     the Company that it is unwilling or unable to continue as Depositary for
     such series or if at any time the Depositary for such series shall no
     longer be registered or in good standing under the Exchange Act, or other
     applicable statute or regulation, and a successor Depositary for such
     series is not appointed by the Company within 90 days after the Company
     receives such notice or becomes aware of such condition, as the case may
     be, 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.

                                      13
<PAGE>

     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.

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.

                                      14
<PAGE>

     (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 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

                                      15
<PAGE>

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 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.

                                  ARTICLE IV

<PAGE>

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

                                      17
<PAGE>

           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.

SECTION 4.04  Appointment to Fill Vacancy in Office of Trustee.

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

     upon any of the Securities of that series, as and when the same shall

     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

     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

     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

     (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 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

                                      21

<PAGE>

     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, 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

                                      22
<PAGE>

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

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

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

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

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

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 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.

                                      24
<PAGE>

     (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
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

                                      25
<PAGE>

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.

                                  ARTICLE VII

                            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:

     (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

                                      26
<PAGE>

     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;

     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);

     (c) The Trustee may consult with counsel and the written advice of such

     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

                                      27
<PAGE>

     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.

     (c) The Trustee shall not be accountable for the use or application by the

     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

     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,

     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.

respect thereof be herein specifically

                                      29
<PAGE>

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

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 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

                                      30
<PAGE>

     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.

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

                                      31
<PAGE>

     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 all such rights, powers and trusts
     referred to in paragraph (a) or (b) of this Section, as the case may be.

                                      32
<PAGE>

        (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.

                                      33
<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:

           (1) 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.

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

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

SECTION 8.03   Who May be Deemed Owners.

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

SECTION 8.04   Certain Securities Owned by Company Disregarded.

                                      34
<PAGE>

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:

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

                                      35
<PAGE>

        (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 shall,
without the consent of the holders of each Security then Outstanding and

                                      36
<PAGE>

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

                                      37
<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.

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

consolidation, or into which the Company shall have been merged, or by the
entity which shall have acquired such property.

     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

                                      38
<PAGE>

     corporation shall be relieved of all obligations and covenants under this
     Indenture and the Securities.

     (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 11.01  Satisfaction and Discharge of Indenture.

If at any time: (a) the Company shall have delivered to the Trustee for
cancellation all Securities of a series theretofore authenticated (other than
any Securities that shall have been destroyed, lost or stolen and that shall

payment money or Governmental Obligations have theretofore been deposited in
trust or segregated and held in trust by the Company (and thereupon repaid to

all such Securities of a particular series not theretofore delivered to the
Trustee for cancellation shall have become due and payable, or are by their
terms to become due and payable within one year or are to be called for
redemption within one year under arrangements satisfactory to the Trustee for
the giving of notice of redemption, and the Company shall deposit or cause to be

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

indentures supplemental to this Indenture, in any case where the date of

illegal or unenforceable provision had never been contained herein or therein.

obligations under this Indenture to a direct or indirect wholly-owned Subsidiary

The Securities shall be issuable as registered Securities and in the

series, as well as any premium thereon in case of redemption thereof prior to

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

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

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:

               Securities to the Persons in whose names such Securities (or
               their respective Predecessor Securities) are registered at the
               close of business on a special record date for the payment of
               such Defaulted Interest, which shall be fixed in the following
               manner: the Company shall notify the Trustee in writing of the
               amount of Defaulted Interest proposed to be paid on each such
               Security and the date of the proposed payment, and at the same
               time the Company shall deposit with the Trustee an amount of
               money equal to the aggregate amount proposed to be paid in
               respect of such Defaulted Interest or shall make arrangements
               satisfactory to the Trustee for such deposit prior to the date of
               the proposed payment, such money when deposited to be held in
               trust for the benefit of the Persons entitled to such Defaulted
               Interest as in this clause provided. Thereupon the Trustee shall
               fix a special record date for the payment of such Defaulted
               Interest which shall not be more than 15 nor less than 10 days
               prior to the date of the proposed payment and not less than 10
               days after the receipt by the Trustee of the notice of the
               proposed payment. The Trustee shall promptly notify the Company
               of such special record date and, in the name and at the expense
               of the Company, shall cause notice of the proposed payment of
               such Defaulted Interest and the special record date therefor to
               be mailed, first class postage prepaid, to each Securityholder at
               his or her address as it appears in the Security Register (as
               hereinafter defined), not less than 10 days prior to such special
               record date. Notice of the proposed payment of such Defaulted
               Interest and the special record date therefor having been mailed
               as aforesaid, such Defaulted Interest shall be paid to the
               Persons in whose names such Securities (or their respective
               Predecessor Securities) are registered on such special record
               date.

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

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

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

                                       8

President thereof, or of any Person who shall have been a Secretary or Assistant
Secretary thereof, 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.

                  (1) 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

                                       9
<PAGE>

                  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.

                  (2) 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 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.

                 (3) 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.

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.

                                      10
<PAGE>

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 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

                                      11
<PAGE>

stolen Security shall be found at any time, or be enforceable by anyone, and
shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of the same series duly issued
hereunder. All Securities shall be held and owned upon the express condition
that the foregoing provisions are exclusive with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities, and shall preclude
(to the extent lawful) any and all other rights or remedies, notwithstanding any
law or statute existing or hereafter enacted to the contrary with respect to the
replacement or payment of negotiable instruments or other securities without
their surrender.

SECTION 2.08  Cancellation.

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

SECTION 2.09 Benefits of Indenture.

Nothing in this Indenture or in the Securities, express or implied, shall give
or be construed to give to any Person, other than the parties hereto and the
holders of the Securities (and, with respect to the provisions of Article
Fourteen, the holders of Senior Indebtedness) 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 (and, with respect to the provisions of Article Fourteen, the
holders of Senior Indebtedness).

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

                                      12
<PAGE>

otherwise authorized under such laws to conduct such business and is subject to
supervision or examination by Federal or State authorities. If at any time any
Authenticating Agent shall cease to be eligible in accordance with these
provisions, it shall resign immediately.

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

SECTION 2.11 Global Securities.

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

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

     (c) If at any time the Depositary for a series of the Securities notifies
     the Company that it is unwilling or unable to continue as Depositary for
     such series or if at any time the Depositary for such series shall no
     longer be registered or in good standing under the Exchange Act, or other
     applicable statute or regulation, and a successor Depositary for such
     series is not appointed by the Company within 90 days after the Company
     receives such notice or becomes aware of such condition, as the case may
     be, 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

                                      13
<PAGE>

     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.

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

                                      14
<PAGE>

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 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).

                                    15
<PAGE>

     (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 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

                                      16
<PAGE>

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.

                                  ARTICLE IV

                                   COVENANTS

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;

                                 17

          (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.

SECTION 4.04 Appointment to Fill Vacancy in Office of Trustee.

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

                                    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;

                                      20
<PAGE>

(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 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, notwithstanding anything contained in this Indenture or in
     the Securities of that series or established with respect to that series
     pursuant to Section 2.01 to the contrary.

     (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

                                      21
<PAGE>

        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, 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

                                      22
<PAGE>

        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, 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.

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

the principal of (and premium, if any) and interest on such Security, as therein
provided, on or after the respective due dates expressed in such Security (or in
the case of redemption, on the redemption date), or to institute suit for the
enforcement of any such payment on or after such respective dates or redemption
date, shall not be impaired or affected without the consent of such holder and
by accepting a Security hereunder it is expressly understood, intended and
covenanted by the taker and holder of every Security of such series with every
other such taker and holder and the Trustee, that no one or more holders of
Securities of such series shall have any right in any manner whatsoever by
virtue or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of the holders of any other of such Securities, or to

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
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

                                      25

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.

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:

                                      26
<PAGE>

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 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

                                      27
<PAGE>

       Company, by the President or an 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);

       (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.

                                      28
<PAGE>

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

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

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

SECTION 7.04 May Hold Securities.

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

SECTION 7.05 Moneys Held in Trust.

Subject to the provisions of Section 11.05, all moneys received by the

Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by law. The Trustee shall be under no
liability for interest on any moneys received by it hereunder except such as it
may agree with the Company to pay thereon.

SECTION 7.06 Compensation and Reimbursement.

        (a)  The Company covenants and agrees to pay to the Trustee, and the
        Trustee shall be entitled to, such reasonable compensation (which shall
        not be limited by any provision of law in regard to the compensation of
        a trustee of an express trust), as the Company, and the Trustee may from
        time to time agree in writing, for all services rendered by it in the
        execution of the trusts hereby created and in the exercise and
        performance of any of the powers and duties hereunder of the Trustee,
        and, except as otherwise expressly provided herein, the Company will pay
        or reimburse the Trustee upon its request for all reasonable expenses,
        disbursements and advances incurred or made by the Trustee in accordance
        with any of the provisions of this Indenture (including the reasonable
        compensation and the expenses and disbursements of its counsel and of
        all Persons not regularly in its employ) except any such expense,
        disbursement or advance as may arise from its negligence or bad faith.
        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

                                      29
<PAGE>

        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.

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.

                                      30

SECTION 7.10 Resignation and Removal; Appointment of Successor.

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

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

        (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

                                      31
<PAGE>

        series by so notifying the Trustee and the Company and may appoint a
        successor Trustee for such series with the consent of the Company.

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

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

SECTION 7.11 Acceptance of Appointment By Successor.

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

        (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

                                      32
<PAGE>

        respect to the Securities of that or those series to which the
        appointment of such successor trustee relates; but, on request of the
        Company or any successor trustee, such retiring Trustee shall duly
        assign, transfer and deliver to such successor trustee, to the extent
        contemplated by such supplemental indenture, the property and money held
        by such retiring Trustee hereunder with respect to the Securities of
        that or those series to which the appointment of such successor trustee
        relates.

        (c) Upon request of any such successor trustee, the Company shall
        execute any and all instruments for more fully and certainly vesting in
        and confirming to such successor trustee all such rights, powers and
        trusts referred to in paragraph (a) or (b) of this Section, as the case
        may be.

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

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

SECTION 7.12  Merger, Conversion, Consolidation or Succession to Business.

Any corporation into which the Trustee may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation
succeeding to the corporate trust business of the Trustee, 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

                                      33
<PAGE>

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.

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.

                                      34
<PAGE>

        (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.

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

                                      35
<PAGE>

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.

                            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:

        (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

                                      36
<PAGE>

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 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

                                      37
<PAGE>

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 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.

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

                                      38
<PAGE>

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)

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

        and satisfactory in form to the Trustee, of the due and punctual payment
        of the principal of, premium, if any, and interest on all of the

        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.

        (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).

The Trustee, subject to the provisions of Section 7.01, may receive an

Opinion of Counsel as conclusive evidence that any such consolidation, merger,

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
date such moneys or Governmental Obligations, as the case may be, are deposited
with the Trustee the obligations of the Company under this Indenture with
respect to such series shall cease to be of further effect except for the
provisions of Sections 2.03, 2.05, 2.07, 4,01, 4.02, 4,03, 7.06, 7.10 and 11.05

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
