                FIRST ALLMERICA FINANCIAL LIFE INSURANCE COMPANY

                       ENHANCED DEATH BENEFIT "EDB" RIDER

OVERVIEW:

The EDB Rider ("Rider") is an optional rider the Owner has selected. It provides
an enhanced Death Benefit, which provides a ratchet.

APPLICABILITY:

The Rider is made a part of the certificate to which it is attached and is
effective on the issue date.

BENEFIT:

The "Death Benefit" provision of the certificate is replaced by the following:

If an Owner, or an Annuitant if the Owner is a non-natural person, dies before
the Annuity Date, the Death Benefit will be the greatest of:

    (a)  the Accumulated Value on the Effective Valuation Date;

    (b)  gross Payments made until the date of death, proportionately reduced
         for subsequent withdrawals and

    (c)  the highest Accumulated Value on any certificate anniversary prior to
         the date of death, as determined after being increased for subsequent
         Payments and proportionately reduced for subsequent withdrawals.

PROPORTIONATE REDUCTION:

Sections (b) and (c) refer to a proportionate reduction. This proportionate
reduction is calculated by multiplying the (b) or (c) value, whichever is
applicable, determined immediately prior to the withdrawal by the following:

                            Amount of the withdrawal
                            ------------------------
        Accumulated Value determined immediately prior to the withdrawal.

CHARGE FOR BENEFIT:

While this Rider is in effect, the Company will assess the EDB Charge (see
Specifications page).

TERMINATION:

This Rider will terminate on the earliest of the following:

    (a)  the Annuity Date;

    (b)  when a Death Benefit is payable and the certificate is not continued
         under a spousal takeover; or

    (c)  surrender of the certificate.

SECTION 3.  DENOMINATIONS;  PROVISIONS FOR PAYMENT.

            (a) 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(11). The Securities of a particular
series shall bear interest payable on the dates and at the rate specified

            (b) 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

otherwise provided in the terms of a series of Securities, at the option of
the Company, payment of interest may be mailed by check to the holders of the
Securities of any series at their respective addresses set forth in the
Security Register. 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

                                      9

<PAGE>

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.

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

            (1) The Company may make payment of any Defaulted Interest on
      Securities to the Persons in whose names such Securities (or their
      respective Predecessor Securities) are registered at the close of business
      on a special record date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner: the Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each such Security and the date of the proposed payment, and at the
      same time the Company shall deposit with the Trustee an amount of money
      equal to the aggre-gate 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 and shall be no longer payable pursuant to the following clause (2).

            (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.

            (d) 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.

            (e) 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 4.  EXECUTION AND AUTHENTICATION.

            Two Officers shall sign the Securities for the Company by manual
or facsimile signature. If an Officer whose signature is on a Security no
longer holds that office at the time the Trustee authenticates the Security,
the Security shall be valid nevertheless.

            A Security shall not be valid until an authorized signatory of
the Trustee manually signs the certificate of authentication on the Security.
The signature shall be conclusive evidence that the Security has been
authenticated under 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 two Officers, 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.

                                      11

SECTION 5.  REGISTRATION OF TRANSFER AND EXCHANGE.

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

            (b) The Company shall keep, or cause to be kept, at its office or
agency designated for such purpose in the Borough of Manhattan, the City and
State of New York, or such other location designated by the Company a register
or registers (herein referred to as the "Security Register") in which, subject
to such reasonable regulations as it may prescribe, the Company shall register
the Securities and the transfers of Securities as in this Article provided and
which at all reasonable times shall be open for inspection by the Trustee.
Unless otherwise specified in a supplemental indenture, the Trustee is hereby
appointed as "Security Registrar" for the purpose of registering Securities and
transfer of Securities of each series.

            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, the second paragraph of Section
3.03 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

                                       12

<PAGE>

or portions thereof called for redemption except the unredeemed portion of
any Securities of any series being redeemed in part. The provisions of this
Section 2.05 are, with respect to any Global Security, subject to Section
2.11 hereof.

SECTION 6.  TEMPORARY SECURITIES.

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

SECTION 7.  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

                                       13

<PAGE>

the payment of the same (without surrender thereof except in the case of a
mutilated Security) if the applicant for such payment shall furnish to the
Company and the Trustee such security or indemnity as they may require to
save them harmless, and, in case of destruction, loss or theft, evidence to
the satisfaction of the Company and the Trustee of the destruction, loss or
theft of such Security and of the ownership thereof.

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

SECTION 8.  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 9.  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 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,

                                       14
<PAGE>

with the consent of the Company, 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 a corporation that has a combined capital and
surplus, as most recently reported or determined by it, sufficient under the
laws of any jurisdiction under which it is organized or in which it is doing
business to conduct a trust business, and that is otherwise authorized under
such laws to conduct such business and is subject to supervision or
examination by Federal or State authorities. If at any time any
Authenticating Agent shall cease to be eligible in accordance with these
provisions, it shall resign immediately.

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

SECTION 11. GLOBAL SECURITIES.

            (a) If the Company shall establish pursuant to Section 2.01 that
the Securities of a particular series are issuable 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, such of the Outstanding Securities of such series as shall be specified
therein and that the aggregate amount of Outstanding Securities represented
thereby may from time to time be increased or reduced to reflect exchanges,
(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." Any endorsement of a Security in
global form to reflect the amount, or any increase or decrease in the amount,
of Outstanding Securities represented thereby shall be made by the Trustee in
such manner and upon instructions given by such Person or Persons as shall be
specified therein or in the written request signed in the name of the
Company, by two Officers thereof to be delivered to the Trustee pursuant to
Section 2.04 or Section 2.06.

                                       15
<PAGE>

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

            (c) If at any time the Depositary for a series of the Securities
notifies the Company that it is unwilling or unable to continue as Depositary
for such series or if at any time the Depositary for such series shall no
longer be registered or in good standing under the Exchange Act, or other
applicable statute or regulation, and a successor Depositary for such series
is not appointed by the Company within 90 days after the Company receives
such notice or becomes aware of such condition, as the case may be, this
Section 2.11 shall no longer be applicable to the Securities of such series
and the Company will execute, and subject to Section 2.05, the Trustee will
authenticate and deliver the Securities of such series in definitive
registered form without coupons, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global
Security of such series in exchange for such Global Security. In addition,
the Company may at any time determine that the Securities of any series shall
no longer be represented by a Global Security and that the provisions of this
Section 2.11 shall no longer apply to the Securities of such series. In such
event the Company will execute and subject to Section 2.05, the Trustee, upon
receipt of an Officers' Certificate evidencing such determination by the
Company, will authenticate and deliver the Securities of such series in
definitive registered form without coupons, in authorized denominations, and
in an aggregate principal amount equal to the principal amount of the Global
Security of such series in exchange for such Global Security. Upon the
exchange of the Global Security for such Securities in definitive registered
form without coupons, in authorized denominations, the Global Security shall
be canceled by the Trustee. Such Securities in definitive registered form
issued in exchange for the Global Security pursuant to this Section 2.11(c)
shall be registered in such names and in such authorized denominations as the
Depositary, pursuant to instructions from its direct or indirect participants
or otherwise, shall instruct the Trustee. The Trustee shall deliver such
Securities to the Depositary for delivery to the Persons in whose names such
Securities are so registered.

                                   ARTICLE III

             REDEMPTION OF SECURITIES AND SINKING FUND PROVISIONS

SECTION 1.  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.

                                       16
<PAGE>

SECTION 2.  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 60 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 (or the manner of calculation thereof) at
which Securities of that series are to be redeemed, and shall state that payment
of the redemption price of such Securities to be redeemed will be made at the
office or agency of the Company in the Borough of Manhattan, the City and State
of New York, upon presentation and surrender of such Securities, that interest
accrued to the date fixed for redemption will be paid as specified in said
notice, that from and after said date interest will cease to accrue and that the
redemption is for a sinking fund, if such is the case. If less than all the
Securities of a series are to be redeemed, the notice to the holders of
Securities of that series to be redeemed in whole or in part shall specify the
particular Securities to be so redeemed. In case any Security is to be redeemed
in part only, the notice that relates to such Security shall state the portion
of the principal amount thereof to be redeemed, and shall state that on and
after the redemption date, upon surrender of such Security, a new Security or
Securities of such series in principal amount equal to the unredeemed portion
thereof will be issued.

            (b) If less than all the Securities of a series are to be redeemed,
the Company shall give the Trustee at least 30 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.

                                       17
<PAGE>

            The Company may, if and whenever it shall so elect, by delivery
of instructions signed on its behalf by any Officer, instruct the Trustee or
any paying agent to call all or any part of the Securities of a particular
series for redemption and to give notice of redemption in the manner set
forth in this Section, such notice to be in the name of the Company or its
own name as the Trustee or such paying agent may deem advisable. In any case
in which notice of redemption is to be given by the Trustee or any such
paying agent, the Company shall deliver or cause to be delivered to, or
permit to remain with, the Trustee or such paying agent, as the case may be,
such Security Register, transfer books or other records, or suitable copies
or extracts therefrom, sufficient to enable the Trustee or such paying agent
to give any notice by mail that may be required under the provisions of this
Section.

SECTION 3.  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 4.  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

                                       18
<PAGE>

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 5.  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 6.  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

                                CERTAIN COVENANTS

SECTION 1.  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.

            The Company will duly and punctually pay or cause to be paid the
principal of and any premium 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.

                                       19
<PAGE>

SECTION 2.  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 hereinabove 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
an Officer 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 3.  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 any premium 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 any premium 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 any premium or interest on Securities of that series, set
aside, segregate and hold in trust for

                                       20
<PAGE>

the benefit of the Persons entitled thereto a sum sufficient to pay such
principal and any premium 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
any premium or interest on any Securities of that series, deposit with the
paying agent a sum sufficient to pay the principal and any premium 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.  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 5.  COMPLIANCE WITH CONSOLIDATION PROVISIONS.

            The Company will not, while any of the Securities remain
Outstanding, consolidate with, or merge into, or merge into itself, 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.

SECTION 6.  STATEMENT BY OFFICERS AS TO DEFAULT.

            The Company will deliver to the Trustee, within 120 days after the
end of each fiscal year of the Company ending after the date hereof, an
Officers' Certificate signed by its principal executive officer, principal
financial officer or principal accounting officer stating whether or not to the
best knowledge of the signer thereof the Company is in default in the
performance and observance of any of the terms, provisions and conditions of
this Indenture, and if the Company shall be in default, specifying all such
defaults and the nature and status thereof of which they may have knowledge.

      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 30 days; provided, however, that a valid extension of an interest
      payment period by the Company in accordance with the terms of any
      indenture supplemental hereto, shall not constitute a default in the
      payment of interest for this purpose;

            (2) the Company defaults in the payment of the principal of (or
      premium, if any, on) any of the Securities of that series as and when the
      same shall become due and payable whether at maturity, upon redemption, by
      declaration or otherwise, or in any payment required by any sinking or
      analogous fund established with respect to that series;

            (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 60 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) if the Securities of the series are convertible into shares of
      common stock or other securities of the Company, failure by the Company to

      such Securities elect to convert such Securities into shares of common
      stock or other securities of the Company;

            (5) 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;

            (6) 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 their respective property, or (iii) orders the
      liquidation of the Company, and the order or decree remains unstayed and
      in effect for 90 days; or

            (7) any other Event of Default provided with respect to Securities
      of that series.

                                       24
<PAGE>

            (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 (or, if the Securities of such series are Original Issue Discount
Securities, such portion of the principal amount as may be specified in the
terms of such series) of, premium, if any, and accrued interest, if any, on all
the Securities of that series to be due and payable immediately, and upon any
such declaration the same shall become and shall be immediately due and payable,
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 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 or Yield to Maturity (in the
case of Original Issue Discount Securities) expressed in the Securities of that
series (or at the respective rates of interest or Yields to Maturity of all the
Securities, as the case may be) 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
non-payment of principal, premium, if any, or interest on Securities of that
series that (or, if any Securities are Original Issue Discount Securities, such
portion of the principal as may be specified in the terms thereof) 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 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.

                                       25

SECTION 2.  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 30 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 reasonable costs and expenses of collection,
and the amount payable to the Trustee under Section 7.06.

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

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

                                       26

<PAGE>

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

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

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

SECTION 3.  APPLICATION OF MONEYS COLLECTED.

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

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

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

SECTION 4.  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

                                       27
<PAGE>

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 any premium and (subject to
Section 2.03) 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 5.  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

                                       28
<PAGE>

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.  CONTROL BY SECURITYHOLDERS.

            The holders of a majority in aggregate principal amount of the
Securities of any series at the time Outstanding, determined in accordance with
Section 8.04, shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee with respect to such series;
PROVIDED, HOWEVER, that such direction shall not be in conflict with any rule of
law or with this Indenture or be unduly prejudicial to the rights of holders of
Securities of such series not consenting; and PROVIDED, FURTHER, that the
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction. Prior to the taking of any action hereunder,
the Trustee shall be entitled to reasonable indemnification satisfactory to the
Trustee against all losses and expenses caused by taking or not taking such
action. 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 8.04, may on behalf of the holders of all of the Securities of such
series waive any past default in the performance of any of the covenants
contained herein or established pursuant to Section 2.01 with respect to such
series and its consequences, except a default in the payment of the principal of
or any premium 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 7.  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

                                       29
<PAGE>

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 1.  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:

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

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

                                       30
<PAGE>

            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 (determined as
      provided in Section 8.04) 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 2.  CERTAIN RIGHTS OF TRUSTEE.

            Except as otherwise provided in Section 7.01:

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

            (b) Any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by a Board Resolution or an instrument
signed in the name of the Company, by two Officers 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,

                                       31
<PAGE>

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 3.  TRUSTEE NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OR SECURITIES.

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

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

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

SECTION 4.    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 5.    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 6.    COMPENSATION AND REIMBURSEMENT.

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

SECTION 7.    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

                                       33

<PAGE>

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 8.    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 9.    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 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 or pursuant to a Board Resolution.
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

                                       34

<PAGE>

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 or pursuant to a Board Resolution, 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 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,

                                       35

<PAGE>

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

            (b) In case of the appointment hereunder of a successor trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor trustee relates, (2)
shall contain such provisions as shall be deemed necessary or desirable to
confirm that all the rights, powers, trusts and duties of the retiring Trustee
with respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust, that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee and that no Trustee shall be responsible for any act or
failure to act on the part of any other Trustee hereunder; and upon the
execution and delivery of such supplemental indenture the resignation or removal
of the retiring Trustee shall become effective to the extent provided therein,
such retiring Trustee shall with respect to the Securities of that or those
series to which the appointment of such successor trustee relates have no
further responsibility for the exercise of rights and powers or for the
performance of the duties and obligations vested in the Trustee under this
Indenture, and each such successor trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor trustee relates; but, on request of
the Company or any successor trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor trustee, to the extent contemplated by
such supplemental indenture, the property and money held by such retiring
Trustee hereunder with respect to the Securities of that or those series to
which the appointment of such successor trustee relates.

            (c) Upon request of any such successor trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to

                                       36

<PAGE>

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 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 13.    PREFERENTIAL COLLECTION OF CLAIMS AGAINST THE COMPANY.

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

SECTION 14.    NOTICE OF DEFAULTS.

            If a default occurs and is continuing hereunder with respect to
Securities of any series and if it is actually known to a Trust Officer of the
Trustee, the Trustee shall mail to each holder of such Securities notice of the
default within 90 days after is occurs PROVIDED, HOWEVER, that in the case of
any default of the character specified in Section 6.01(3) with respect to
Securities of such series, no such notice to Holders shall be given until at
least 30 days after the occurrence thereof. Except in the case of a default in
payment of principal of or interest on any Security (including payments pursuant
to the mandatory redemption provisions of such Security, if any), the Trustee
may withhold the notice if and so long as a committee of its Trust Officers in
good faith determines that

                                       37

<PAGE>

withholding the notice is not opposed to the interest of the holders of such
Securities. For the purpose of this Section, the term "default" means any
event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to Securities of such series.

                                  ARTICLE VIII

                         CONCERNING THE SECURITYHOLDERS

SECTION 1.    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 2.    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.

                                       38

<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 3.    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 4.    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 5.    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.

                                       39

<PAGE>

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 1.    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

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;

            (g) to add to, delete from, or revise the conditions, limitations,
and restrictions on the authorized amount, terms, or purposes of issue,

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

            (i) to provide for the issuance of and establish the form and terms

Commission in connection with qualifying, or maintaining the qualification of,
this Indenture under the Trust Indenture Act.

            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.

Securities of each series affected by such supplemental indenture or indentures
at the time Outstanding, the Company, when authorized by Board Resolutions, and

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

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 3.    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

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 4.    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 Trustee and the Company, to any modification of this Indenture
contained in any such supplemental indenture may be prepared and executed by the
Company, authenticated by the Trustee and delivered in exchange for the
Securities of that series then Outstanding.

Resolutions authorizing the execution of any such supplemental indenture, and
upon the filing with the Trustee of evidence of the consent of Securityholders

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.

SECTION 6.    CONFORMITY WITH TRUST INDENTURE ACT.

SECTION 1.    COMPANY MAY CONSOLIDATE, ETC.

            Unless otherwise specified in a supplemental indenture hereto,
nothing contained in this Indenture or in any of the Securities shall prevent
any consolidation or merger of the Company with or into any other Person
(whether or not affiliated with the Company) or successive consolidations or
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 Person (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, merger, sale, conveyance, transfer or other
disposition, the due and punctual payment of the principal of and any premium
and interest on all of the Securities of all series in accordance with the terms
of each series, according to their tenor and the due and punctual performance
and observance of all the covenants and conditions of this Indenture with
respect to each series or established with respect to such series pursuant to
Section 2.01 to be kept or performed by the Company shall be expressly assumed,
by supplemental indenture satisfactory in form to the Trustee executed and
delivered to the Trustee by the entity formed by such consolidation, or into
which the Company shall have been merged, or by the entity which shall have
acquired such property.

SECTION 2.    SUCCESSOR SUBSTITUTED.

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

indenture, executed and delivered to the Trustee and satisfactory in form to
the Trustee, of the due and punctual payment of the principal of and any

the due and punctual performance of all of the covenants and conditions of
this Indenture or established with respect to each series of the Securities
pursuant to Section 2.01 to be performed by the Company with respect to each
series, such successor Person 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 Person 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 Indenture or in any of the Securities
shall prevent the Company from merging into itself or acquiring by purchase or
otherwise all or any part of the property of any other Person (whether or not
affiliated with the Company).

SECTION 3.    EVIDENCE OF CONSOLIDATION, ETC. TO TRUSTEE.

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

assumption, comply with the provisions of this Article.

                           SATISFACTION AND DISCHARGE

SECTION 1.    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 ben destroyed, lost or stolen and that shall
have been replaced or paid as provided in Section 2.07 and Securities for whose
payment money or Governmental Obligations have theretofore been deposited in
trust or segregated and held in trust by the Company and thereupon repaid to the
Company or discharged from such trust, as provided in Section 11.05); or (b) 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 deposited with the
Trustee as trust funds an amount of money in U.S. dollars sufficient, or
non-callable Governmental Obligations, the principal of and interest on which
when due, will be sufficient or a combination thereof, sufficient in the opinion
of a nationally recognized firm of

                                       44
<PAGE>

independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay at maturity or upon redemption all
Securities of that series not theretofore delivered to the Trustee for
cancellation, including principal and any premium 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 with respect to such series by the Company then this
Indenture shall thereupon cease to be of further effect with respect to such
series except for the provisions of Sections 2.03, 2.05, 2.07, 4.01, 4.02,
4.03 and 7.10, that shall survive until the date of maturity or redemption
date, as the case may be, and Sections 7.06 and 11.05, that shall survive to
such date and thereafter, and the Trustee, on demand of the Company and at
the cost and expense of the Company shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture with respect to
such series.

SECTION 2.    DISCHARGE OF OBLIGATIONS.

            If at any time all such Securities of a particular series not
heretofore delivered to the Trustee for cancellation or that have not become due
and payable as described in Section 11.01 shall have been paid by the Company by
depositing irrevocably with the Trustee as trust funds money in U.S. dollars
sufficient or an amount of non-callable Governmental Obligations, the principal
of and interest on which when due, will be sufficient or a combination thereof,
sufficient in the opinion of a nationally recognized firm of independent public
accountants expressed in a written certification thereof delivered to the
Trustee, to pay at maturity or upon redemption all such Securities of that
series not theretofore delivered to the Trustee for cancellation, including
principal and any premium 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 hereof that shall survive
until such Securities shall mature and be paid. Thereafter, Sections 7.06 and
11.05 shall survive.

SECTION 3.    DEPOSITED MONEYS TO BE HELD IN TRUST.

            All moneys or Governmental Obligations deposited with the Trustee
pursuant to Sections 11.01 or 11.02 shall be held in trust and shall be

(including the Company acting as its own paying agent), to the holders of the
particular series of Securities for the payment or redemption of which such
moneys or Governmental Obligations have been deposited with the Trustee.

            In connection with the satisfaction and discharge of this Indenture
all moneys or Governmental Obligations then held by any paying agent under the
provisions of this Indenture shall, upon demand of the Company, be paid to the
Trustee and thereupon such paying agent shall be released from all further
liability with respect to such moneys or Governmental Obligations.

SECTION 5.    REPAYMENT TO COMPANY.

            Any moneys or Governmental Obligations deposited with any paying
agent or the Trustee, or then held by the Company, in trust for payment of
principal of or premium or interest on the Securities of a particular series
that are not applied but remain unclaimed by the holders of such Securities for
at least two years after the date upon which the principal of and any premium 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
creditor, look only to the Company for the payment thereof.

of this Indenture, or of any Security, or for any claim based thereon or
otherwise in respect thereof, shall be had against any incorporator,
stockholder, officer or director, past, present or future as such, of the
Company or of any predecessor or successor corporation, either directly or
through the Company or any such predecessor or successor corporation, whether
by virtue of any constitution, statute or rule of law, or by the enforcement
of any assessment or penalty or otherwise; it being expressly understood that
this Indenture and the obligations issued hereunder are solely corporate
obligations, and that no such personal liability whatever shall attach to, or
is or shall be incurred by, the incorporators, stockholders, officers or
directors as such, of the Company or of any predecessor or successor
corporation, or any of them, because of the creation of the indebtedness
hereby authorized, or under or by reason of the obligations, covenants or
agreements contained in this Indenture or in any of the Securities or implied
therefrom; and that any and all such personal liability of every name and
nature, either at common law or in equity or by constitution or statute, of,
and any and all such rights and claims against, every such incorporator,
stockholder, officer or director as such, because of the creation of the
indebtedness hereby authorized, or under or by reason of the obligations,
covenants or

                                       46
<PAGE>

agreements contained in this Indenture or in any of the Securities or implied
therefrom, are hereby expressly waived and released as a condition of, and as
a consideration for, the execution of this Indenture and the issuance of such
Securities.

                                  ARTICLE XIII

                            MISCELLANEOUS PROVISIONS

SECTION 1.    EFFECT ON SUCCESSORS AND ASSIGNS.

            All the covenants, stipulations, promises and agreements in this
Indenture contained by or on behalf of the Company shall bind their respective
successors and assigns, whether so expressed or not.

SECTION 2.    ACTIONS BY SUCCESSOR.

            Any act or proceeding by any provision of this Indenture authorized
or required to be done or performed by any board, committee or officer of the
Company shall and may be done and performed with like force and effect by the
corresponding board, committee or officer of any Person that shall at the time
be the lawful sole successor of the Company.

SECTION 3.    NOTICES.

            Except as otherwise expressly provided herein any notice or demand
that by any provision of this Indenture is required or permitted to be given or
served by the Trustee or by the holders of Securities to or on the Company may
be given or served by being deposited first class postage prepaid in a
post-office letterbox addressed (until another address is filed in writing by
the Company with the Trustee), as follows: CT Corporation System, 111 Eighth
Avenue, 13th Floor, New York, NY 10019. Any notice, election, request or demand
by the Company or any Securityholder to or upon the Trustee shall be deemed to
have been sufficiently given or made, for all purposes, if given or made in
writing at the Corporate Trust Office of the Trustee.

SECTION 4.    NOTICE TO HOLDERS OF SECURITIES; WAIVER.

            Except as otherwise expressly provided herein, where this Indenture
provides for notice to holders of Securities of any event, such notice shall be
sufficiently given to holders of Securities if in writing and mailed,
first-class postage prepaid, to each holder of a Security affected by such
event, at the address of such holder as it appears in the Security Register, not
earlier than the earliest date, and not later than the latest date, prescribed
for the giving of such notice.

            In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice to
holders of Securities by mail, then such notification as shall be made with the
approval of the Trustee shall

                                       47
<PAGE>

constitute sufficient notice to such holder for every purpose hereunder. In
any case where notice to holders of Securities is given by mail, neither the
failure to mail such notice, nor any defect in any notice mailed to any
particular holder of a Security shall affect the sufficiency of such notice
with respect to other holders of Securities given as provided herein.

            Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice. Waivers of notice by holders of Securities shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

SECTION 5.    GOVERNING LAW.

            This Indenture and each Security shall be deemed to be a contract
made under the internal laws of the State of New York, and for all purposes
shall be construed in accordance with the laws of said State.

SECTION 6.    EFFECT OF HEADINGS AND TABLE OF CONTENTS.

shall furnish to the Trustee an Officers' Certificate stating that all
conditions precedent provided for in this Indenture relating to the proposed
action have been complied with and an Opinion of Counsel stating that in the
opinion of such counsel all such conditions precedent have been complied with,
except that in the case of any such application or demand as to which the
furnishing of such documents is specifically required by any provision of this
Indenture relating to such particular application or demand, no additional
certificate or opinion need be furnished.

            (b) Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
in this Indenture shall include (1) a statement that the Person making such
certificate or opinion has read such covenant or condition; (2) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based; (3) a statement that, in the opinion of such Person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with; and (4) a statement as to whether or not, in the opinion of such
Person, such condition or covenant has been complied with.

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

SECTION 9.    CONFLICT WITH TRUST INDENTURE ACT.

            If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with the duties imposed by Section 318(c) of the Trust
Indenture Act, such imposed duties shall control.

SECTION 10.    COUNTERPARTS.

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

SECTION 11.    SEPARABILITY.

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

SECTION 12.    ASSIGNMENT.

            The Company will have the right at all times to assign any of its
rights or obligations under this Indenture to a direct or indirect wholly-owned
Subsidiary of the Company, PROVIDED that, in the event of any such assignment,
the Company, will remain liable for all such obligations. Subject to the
foregoing, the Indenture is binding upon and inures to the benefit of the
parties thereto and their respective successors and assigns. This Indenture may
not otherwise be assigned by the parties thereto.
