        (c) In connection with the issuance and sale of the Trust Preferred
Securities, the Depositor shall have the right and responsibility to assist the
Issuer Trust with respect to, or effect on behalf of the Issuer Trust, the
following (and any actions taken by the Depositor in furtherance of the
following prior to the date of this Trust Agreement are hereby ratified and
confirmed in all respects):

            (i) the preparation and filing by the Issuer Trust with the
        Commission of and the execution on behalf of the Issuer Trust of a
        registration statement on the appropriate form in relation to the Trust
        Preferred Securities, including any amendments thereto;

            (ii) the determination of the states in which to take appropriate
        action to qualify or register for sale all or part of the Trust
        Preferred Securities and the determination of any and all such acts,
        other than actions that must be taken by or on behalf of the Issuer
        Trust, and the advice to the Issuer Trust of actions they must take on
        behalf of the Issuer Trust, and the preparation for execution and filing
        of any documents to be executed and filed by the Issuer Trust or on
        behalf of the Issuer Trust, as the Depositor deems necessary or
        advisable in order to comply with the applicable laws of any such
        states;

            (iii) the preparation for filing by the Issuer Trust and execution
        on behalf of the Issuer Trust of an application to the New York Stock
        Exchange or any other national stock exchange or the Nasdaq National
        Market or any other automated quotation system for listing upon notice
        of issuance of any Trust Preferred Securities and filing with such
        exchange or self-regulatory organization such notification and documents
        as may be necessary from time to time to maintain such listing;

            (iv) the negotiation of the terms of, and the execution and delivery

        carryout any of the foregoing activities.

        (d) Notwithstanding anything herein to the contrary, the Administrative
Trustees are authorized and directed to conduct the affairs of the Issuer Trust
and to operate the Issuer Trust so that the Issuer Trust will not be deemed to
be an "investment company" required to be registered under the Investment
Company Act, and will not be taxable as a corporation or classified as other
than a grantor trust for United States Federal income tax purposes and so that
the Debentures will be treated as indebtedness of the Depositor for United
States Federal income tax purposes. In this connection, the Depositor and the
Administrative Trustees are authorized to


                                       15
<PAGE>   20

take any action, not inconsistent with applicable law, the Certificate of Trust
or this Trust Agreement, that they determine in their discretion to be necessary
or desirable for such purposes, as long as such action does not adversely affect
in any material respect the interests of the Holders of the Outstanding Trust
Preferred Securities. In no event shall the Depositor or the Issuer Trustees be
liable to the Issuer Trust or the Holders for any failure to comply with this
section that results from a change in law or regulation or in the interpretation
thereof.

    SECTION 2.8. ASSETS OF TRUST.

        The assets of the Issuer Trust shall consist solely of the Trust
Property.

    SECTION 2.9. TITLE TO TRUST PROPERTY.

Property Trustee (in its capacity as such) and shall be held and administered by
the Property Trustee in trust for the benefit of the Issuer Trust and the
Holders in accordance with this Trust Agreement.

    SECTION 3.1. PAYMENT ACCOUNT.

        (a) On or prior to the Closing Date, the Property Trustee shall

Account in accordance with this Trust Agreement. All monies and other property
deposited or held from time to time in the Payment Account shall be held by the
Property Trustee in the Payment Account for the exclusive benefit of the Holders
and for distribution as herein provided, including (and subject to) any priority
of payments provided for herein.

        (b) The Property Trustee shall deposit in the Payment Account, promptly
upon receipt, all payments of principal of or interest on, and any other

                            DISTRIBUTIONS; REDEMPTION

    SECTION 4.1. DISTRIBUTIONS.

        (a) The Trust Securities represent undivided beneficial interests in the
Trust Property, and Distributions (including of Additional Amounts) will be made
on the Trust Securities at the rate and on the dates that payments of interest
(including of Additional Interest, as defined in the Indenture) are made on the
Debentures. Accordingly:

            (i) Distributions on the Trust Securities shall be cumulative, and
        will accumulate whether or not there are funds of the Trust available
        for the payment of


                                       16
<PAGE>   21

        Distributions. Distributions shall accumulate from _____________, 2001
        and, except in the event (and to the extent) that the Depositor
        exercises its right to defer the payment of interest on the Debentures
        pursuant to the Indenture, shall be payable quarterly in arrears on the
        ____ day of ___________, ____________, ____________ and ___________ of
        each year, commencing on _____________, 2001. If any date on which a
        Distribution is otherwise payable on the Trust Securities is not a
        Business Day, then the payment of such Distribution shall be made on the
        next succeeding day that is a Business Day (and without any interest or
        other payment in respect of any such delay), with the same force and
        effect as if made on the date on which such payment was originally
        payable, except that, if such Business Day falls in the next calendar
        year, such payment will be made on the immediately preceding Business
        Day, in each case, with the same force and effect as if made on such
        date (each date on which distributions are payable in accordance with
        this Section 4.1(a), a "Distribution Date").

            (ii) In the event (and to the extent) that the Depositor exercises
        its right under the Indenture to defer the payment of interest on the
        Debentures, Distributions on the Trust Securities shall be deferred but
        shall continue to accumulate. Distributions on the Trust Securities
        shall be payable at a rate of ______% per annum of the Liquidation
        Amount of the Trust Securities. The amount of Distributions payable for
        any full quarterly period shall be computed on the basis of a 360-day
        year of twelve 30-day months. The amount of Distributions for any
        partial period shall be computed on the basis of the actual number of
        days elapsed in a 360-day year of twelve 30-day months. The amount of
        Distributions payable for any period shall include the Additional
        Amounts, if any.

            (iii) Distributions on the Trust Securities shall be made by the
        Property Trustee from the Payment Account and shall be payable on each
        Distribution Date only to the extent that the Issuer Trust has funds
        then on hand and available in the Payment Account for the payment of
        such Distributions.

        (b) Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities at the close of business on the relevant
record date for such Distribution Date, which shall be one Business Day prior to
such Distribution Date; provided, however, that in the event that the Trust
Preferred Securities do not remain in book-entry-only form, the relevant record
date for a Distribution Date shall be the date 15 days prior to such
Distribution Date. Distributions payable on any Trust Securities that are not
punctually paid on any Distribution Date will cease to be payable to the Person
in whose name such Trust Securities are registered on the relevant record date,
and such defaulted Distribution will instead be payable to the Person in whose
name such Trust Securities are registered on the special record date or other
specified date for determining Holders entitled to such defaulted interest
established in accordance with the Indenture.

    SECTION 4.2. REDEMPTION.

Securities at the Redemption Price.


                                       17
<PAGE>   22

        (b) Notice of redemption shall be given by the Property Trustee by
first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days
prior to the Redemption Date to each Holder of Trust Securities to be redeemed,
at such Holder's address appearing in the Security Register. All notices of
redemption shall state:

            (i) the Redemption Date;

            (ii) the Redemption Price or if the Redemption Price cannot be
        calculated prior to the time the notice is required to be sent, the
        estimate of the Redemption Price together with a statement that it is an
        estimate and that the actual Redemption Price will be calculated on the
        third Business Day prior to the Redemption Date (and if an estimate is
        provided, a further notice shall be sent of the actual Redemption Price
        on the date that such Redemption Price is calculated);

            (iii) the CUSIP number or CUSIP numbers of the Trust Preferred
        Securities affected;

            (iv) if less than all the Outstanding Trust Securities are to be
        redeemed, the identification and the aggregate Liquidation Amount of the
        particular Trust Securities to be redeemed;

            (v) that on the Redemption Date the Redemption Price will become due
        and payable upon each such Trust Security to be redeemed and that
        Distributions thereon will cease to accumulate on and after said date,
        except as provided in Section 4.2(d) below; and

            (vi) if the Trust Preferred Securities are no longer in
        book-entry-only form, the place or places where the Trust Preferred
        Securities Certificates are to be surrendered for the payment of the
        Redemption Price.

        (c) The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption of Debentures. Redemptions of the Trust Securities shall be made and
the Redemption Price shall be payable on each Redemption Date only to the extent
that the Issuer Trust has funds then on hand and available in the Payment
Account for the payment of such Redemption Price.

        (d) If the Property Trustee gives a notice of redemption in respect of
any Trust Preferred Securities, then, by 12:00 noon, New York City time, on the
Redemption Date, subject to Section 4.2(c), the Property Trustee will, with
respect to Book-Entry Trust Preferred Securities, irrevocably deposit with the
Clearing Agency for such Book-Entry Trust Preferred Securities, to the extent
available therefor, funds sufficient to pay the applicable Redemption Price and
will give such Clearing Agency irrevocable instructions and authority to pay the
Redemption Price to the Holders of the Trust Preferred Securities. With respect
to Trust Preferred Securities that are not Book-Entry Trust Preferred
Securities, the Property Trustee, subject to Section 4.2(c), will irrevocably
deposit with the Paying Agent, to the extent available therefor, funds
sufficient to pay the applicable Redemption Price and will give the Paying Agent
irrevocable instructions and authority to pay the Redemption Price to the
Holders of the Trust Preferred Securities upon surrender of their Trust
Preferred Securities Certificates.


                                       18
<PAGE>   23

Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Trust Securities called for redemption shall be payable
to the Holders of such Trust Securities as they appear on the Securities
Register for the Trust Securities on the relevant record dates for the related
Distribution Dates. If notice of redemption shall have been given and funds
deposited as required, then upon the date of such deposit, all rights of Holders
holding Trust Securities so called for redemption will cease, except the right
of such Holders to receive the Redemption Price and any Distribution payable in
respect of the Trust Securities on or prior to the Redemption Date, but without
interest, and such Trust Securities will cease to be outstanding. In the event
that any date on which any Redemption Price is payable is not a Business Day,
then payment of the Redemption Price payable on such date will be made on the
next succeeding day that is a Business Day (without any interest or other
payment in respect of any such delay), except that, if such Business Day falls
in the next calendar year, such payment will be made on the immediately
preceding Business Day, in each case, with the same force and effect as if made
on such date. In the event that payment of the Redemption Price in respect of
any Trust Securities called for redemption is improperly withheld or refused and
not paid either by the Issuer Trust or by the Depositor pursuant to the
Guarantee, Distributions on such Trust Securities will continue to accumulate,
as set forth in Section 4.1, from the Redemption Date originally established by
the Issuer Trust for such Trust Securities to the date such Redemption Price is
actually paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.

        (e) Subject to Section 4.3(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated pro
rata to the Common Securities and the Trust Preferred Securities based upon the
relative Liquidation Amounts of such classes. The particular Trust Preferred
Securities to be redeemed shall be selected on a pro rata basis based upon their
respective Liquidation Amounts not more than 60 days prior to the Redemption
Date by the Property Trustee from the Outstanding Trust Preferred Securities not
previously called for redemption, provided that so long as the Trust Preferred
Securities are in book-entry-only form, such selection shall be made in
accordance with the customary procedures for the Clearing Agency for the Trust
Preferred Securities. The Property Trustee shall promptly notify the Securities
Registrar in writing of the Trust Preferred Securities selected for redemption
and, in the case of any Trust Preferred Securities selected for partial
redemption, the Liquidation Amount thereof to be redeemed. For all purposes of
this Trust Agreement, unless the context otherwise requires, all provisions
relating to the redemption of Trust Preferred Securities shall relate, in the
case of any Trust Preferred Securities redeemed or to be redeemed only in part,
to the portion of the aggregate Liquidation Amount of Trust Preferred Securities
that has been or is to be redeemed.

    SECTION 4.3. RANKING OF COMMON SECURITIES.

        (a) Payment of Distributions (including any Additional Amounts) on, the
Redemption Price of, and the Liquidation Distribution in respect of the Trust
Securities, as applicable, shall be made, subject to Section 4.2(e), pro rata
among the Common Securities and the Trust Preferred Securities based on the
Liquidation Amount of the Trust Securities, except that if an Event of Default
has occurred and is continuing, the rights of the Holders of the Common


                                       19
<PAGE>   24

        Securities to payment in respect of distributions and payments upon
liquidation, redemption and otherwise will be subordinated to the rights of the
Holders of the Trust Preferred Securities.

        (b) In the case of the occurrence of any Event of Default resulting from
any Debenture Event of Default, the Holders of the Common Securities shall have
no right to act with respect to any such Event of Default under this Trust
Agreement until the effect of all such Events of Default with respect to the
Trust Preferred Securities have been cured, waived or otherwise eliminated.
Until all such Events of Default under this Trust Agreement with respect to the
Trust Preferred Securities have been so cured, waived or otherwise eliminated,
the Property Trustee shall act solely on behalf of the Holders of the Trust
Preferred Securities and not on behalf of the Holders of the Common Securities,
and only the Holders of the Trust Preferred Securities will have the right to
direct the Property Trustee to act on their behalf.

    SECTION 4.4. PAYMENT PROCEDURES.

        Payments of Distributions (including any Additional Amounts) in respect
of the Trust Preferred Securities shall be made by check mailed to the address
of the Person entitled thereto as such address shall appear on the Securities
Register or, if the Trust Preferred Securities are held by a Clearing Agency,
such Distributions shall be made to the Clearing Agency in immediately available
funds. Payments in respect of the Common Securities shall be made in such manner
as shall be mutually agreed between the Property Trustee and the Holders of the
Common Securities.

    SECTION 4.5. TAX RETURNS AND REPORTS.

        The Administrative Trustees shall prepare (or cause to be prepared), at
the Depositor's expense, and file all United States Federal, state and local tax

Issuer Trust. In this regard, the Administrative Trustees shall (a) prepare and
file (or cause to be prepared and filed) all Internal Revenue Service forms
required to be filed in respect of the Issuer Trust in each taxable year of the
Issuer Trust, and (b) prepare and furnish (or cause to be prepared and
furnished) to each Holder all Internal Revenue Service forms required to be
provided by the Issuer Trust. The Administrative Trustees shall provide the
Depositor and the Property Trustee with a copy of all such returns and reports
promptly after such filing or furnishing. The Issuer Trustees shall comply with
United States Federal withholding and backup withholding tax laws and
information reporting requirements with respect to any payments to Holders under
the Trust Securities.

    SECTION 4.6. PAYMENT OF EXPENSES OF THE ISSUER TRUST.

        The Depositor shall pay to the Issuer Trust, and reimburse the Issuer
Trust for, the full amount of any costs, expenses or liabilities of the Issuer
Trust (other than obligations of the Issuer Trust to pay the Holders of any
Trust Preferred Securities or other similar interests in the Issuer Trust the
amounts due such Holders pursuant to the terms of the Trust Preferred Securities
or such other similar interests, as the case may be), including, without
limitation, any taxes, duties or other governmental charges of whatever nature
(other than withholding taxes) imposed on the Issuer Trust by the United States
or any other taxing authority. Such payment obligation


                                       20
<PAGE>   25

includes any such costs, expenses or liabilities of the Issuer Trust that are
required by applicable law to be satisfied in connection with a dissolution of
the Issuer Trust.

    SECTION 4.7. PAYMENTS UNDER INDENTURE OR PURSUANT TO DIRECT ACTIONS.

        Any amount payable hereunder to any Holder of Trust Preferred Securities

Trustee shall be validly issued and entitled to the benefits of this Trust
Agreement, notwithstanding that such individuals or any of them shall have
ceased to be so authorized prior to the delivery of such Trust Securities
Certificates or did not hold such offices at the date of delivery of such Trust
Securities Certificates. A transferee of a Trust Securities Certificate shall
become a Holder, and shall be entitled to the rights and subject to the

                SECURITIES CERTIFICATES.

        The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of Trust
Preferred Securities Certificates (the "Securities Register") in which the
transfer agent and registrar designated by the Depositor (the "Securities
Registrar"), subject to such reasonable regulations as it may prescribe, shall
provide for the registration of Trust Preferred Securities Certificates and
Common Securities Certificates (subject to Section 5.10 in the case of the
Common Securities Certificates) and registration of transfers and exchanges of
Trust Preferred Securities Certificates as herein provided. The Bank shall be
the initial Securities Registrar.

        Upon surrender for registration of transfer of any Trust Preferred
Securities Certificate at the office or agency maintained pursuant to Section
5.8, the Administrative Trustees or any one of them shall execute on behalf of
the Issuer Trust and deliver, in the name of the designated transferee or

of execution by such Administrative Trustee or Trustees. The Securities
Registrar shall not be required to register the transfer of any Trust Preferred
Securities that have been called for redemption during a period beginning at the
opening of business 15 days before the day of selection for such redemption.

        At the option of a Holder, Trust Preferred Securities Certificates may
be exchanged for other Trust Preferred Securities Certificates in authorized
denominations of the same class and of a like aggregate Liquidation Amount upon
surrender of the Trust Preferred Securities Certificates to be exchanged at the
office or agency maintained pursuant to Section 5.8.

        Every Trust Preferred Securities Certificate presented or surrendered
for registration of transfer or exchange shall be accompanied by a written
instrument of transfer in form satisfactory to an Administrative Trustee and the
Securities Registrar duly executed by the Holder or his attorney duly authorized
in writing. Each Trust Preferred Securities Certificate surrendered for
registration of transfer or exchange shall be canceled and subsequently disposed
of by an Administrative Trustee or the Securities Registrar in accordance with
such Person's customary practice.

        No service charge shall be made for any registration of transfer or
exchange of Trust Preferred Securities Certificates, but the Securities
Registrar may require payment of a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any transfer or
exchange of Trust Preferred Securities Certificates.

    SECTION 5.5. MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
                 CERTIFICATES.

to the Securities Registrar, or if the Securities Registrar shall receive
evidence to its satisfaction of the destruction, loss or theft of any Trust
Securities Certificate, and (b) there shall be delivered to the Securities
Registrar and the Administrative Trustees such security or indemnity as may be
required by them to save each of them harmless, then in the absence of notice

Administrative Trustees, or any one of them, on behalf of the Issuer Trust shall
execute and make available for delivery, in exchange for or in lieu of any such

the issuance of any new Trust Securities Certificate under this Section 5.5, the
Administrative Trustees or the Securities Registrar may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection therewith. Any duplicate Trust Securities Certificate issued
pursuant to this Section shall constitute conclusive evidence of an undivided
beneficial interest in the assets of the Issuer Trust corresponding to that

originally issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

    SECTION 5.6. PERSONS DEEMED HOLDERS.

        The Issuer Trustees and the Securities Registrar shall each treat the
Person in whose name any Trust Securities Certificate shall be registered in the

none of the Issuer Trustees, the Administrative Trustees and the Securities
Registrar shall be bound by any notice to the contrary.

    SECTION 5.7. ACCESS TO LIST OF HOLDERS' NAMES AND ADDRESSES.

        Each Holder and each Owner shall be deemed to have agreed not to hold
the Depositor, the Property Trustee, the Delaware Trustee or the Administrative
Trustees accountable by reason of the disclosure of its name and address,
regardless of the source from which such information was derived.

    SECTION 5.8. MAINTENANCE OF OFFICE AGENCY.

        The Administrative Trustees shall designate an office or offices or
agency or agencies where Trust Preferred Securities Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Issuer Trustees in respect of the Trust Securities
Certificates may be served. The Administrative Trustees initially designate
Wilmington Trust Company, Rodney Square North, 1100 North Market Street,
Wilmington, Delaware 19890-0001, Attention: Corporate Trust Administration, as
its office and agency for such purposes. The Administrative Trustee shall give
prompt written notice to the Depositor, the Property Trustees and to the Holders
of any change in the location of the Securities Register or any such office or
agency.

    SECTION 5.9. APPOINTMENT OF PAYING AGENT.

        The Paying Agent shall make Distributions to Holders from the Payment
Account and shall report the amounts of such Distributions to the Property
Trustee and the Administrative Trustees. Any Paying Agent shall have the
revocable power to withdraw funds from the Payment Account solely for the
purpose of making the Distributions referred to above. The Property Trustee may
revoke such power and remove the Paying Agent in its sole discretion. The Paying
Agent shall initially be [Name]. Any Person acting as Paying Agent shall be


                                       23
<PAGE>   28

permitted to resign as Paying Agent upon 30 days' written notice to the
Administrative Trustees and the Property Trustee. If [Name] shall no longer be
the Paying Agent or a successor Paying Agent shall resign or its authority to
act be revoked, the Property Trustee shall appoint a successor (which shall be a
bank or trust company) that is reasonably acceptable to the Administrative
Trustees to act as Paying Agent. Such successor Paying Agent or any additional
Paying Agent shall execute and deliver to the Issuer Trustees an instrument in
which such successor Paying Agent or additional Paying Agent shall agree with
the Issuer Trustees that as Paying Agent, such successor Paying Agent or
additional Paying Agent will hold all sums, if any, held by it for payment to
the Holders in trust for the benefit of the Holders entitled thereto until such
sums shall be paid to such Holders. The Paying Agent shall return all unclaimed
funds to the Property Trustee and upon removal of a Paying Agent such Paying
Agent shall also return all funds in its possession to the Property Trustee. The
provisions of Sections 8.1, 8.3 and 8.6 herein shall apply to [Name] also in its
role as Paying Agent, for so long as [Name.] shall act as Paying Agent and, to
the extent applicable, to any other paying agent appointed hereunder. Any
reference in this Agreement to the Paying Agent shall include any co-paying
agent unless the context requires otherwise.

    SECTION 5.10. OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

        At the Time of Delivery, the Depositor shall acquire, and thereafter
shall retain, beneficial and record ownership of the Common Securities. To the
fullest extent permitted by law, other than a transfer in connection with a
consolidation or merger of the Depositor into another Person, or any conveyance,
transfer or lease by the Depositor of its properties and assets substantially as
an entirety to any Person, pursuant to Section 801 of the Indenture, any
attempted transfer of the Common Securities shall be void. The Administrative
Trustees shall cause each Common Securities Certificate issued to the Depositor
to contain a legend stated "THIS CERTIFICATE IS NOT TRANSFERABLE TO ANY PERSON
EXCEPT AS DESCRIBED IN THE TRUST AGREEMENT (AS DEFINED BELOW)".

    SECTION 5.11. BOOK-ENTRY TRUST PREFERRED SECURITIES CERTIFICATES; COMMON
                  SECURITIES CERTIFICATE.

        (a) The Trust Preferred Securities Certificates, upon original issuance,
will be issued in the form of a typewritten Trust Preferred Securities
Certificate or Certificates representing Book-Entry Trust Preferred Securities
Certificates, to be delivered to DTC, the initial Clearing Agency, by, or on
behalf of, the Issuer Trust. Such Trust Preferred Securities Certificate or
Certificates shall initially be registered on the Securities Register in the
name of Cede & Co., the nominee of the initial Clearing Agency, and no Owner
will receive a Definitive Trust Preferred Securities Certificate representing
such Owner's interest in such Trust Preferred Securities, except as provided in
Section 5.13. Unless and until Definitive Trust Preferred Securities
Certificates have been issued to Owners pursuant to Section 5.13;

            (i) the provisions of this Section 5.11(a) shall be in full force
        and effect;

            (ii) the Securities Registrar and the Trustees shall be entitled to
        deal with the Clearing Agency for all purposes of this Trust Agreement
        relating to the Book-Entry Trust Preferred Securities Certificates
        (including the payment of the Liquidation Amount


                                       24
<PAGE>   29

        of and Distributions on the Trust Preferred Securities evidenced by
        Book-Entry Trust Preferred Securities Certificates and the giving of
        instructions or directions to Owners of Trust Preferred Securities
        evidenced by Book-Entry Trust Preferred Securities Certificates) as the
        sole Holder of Trust Preferred Securities evidenced by Book-Entry Trust
        Preferred Securities Certificates and shall have no obligations to the
        Owners thereof;

            (iii) to the extent that the provisions of this Section 5.11
        conflict with any other provisions of this Trust Agreement, the
        provisions of this Section 5.11 shall control; and

            (iv) the rights of the Owners of the Book-Entry Trust Preferred
        Securities Certificate shall be exercised only through the Clearing
        Agency and shall be limited to those established by law and agreements
        between such Owners and the Clearing Agency and/or the Clearing Agency
        Participants. Pursuant to the Certificate Depository Agreement, unless
        and until Definitive Trust Preferred Securities Certificates are issued
        pursuant to Section 5.13, the initial Clearing Agency will make
        book-entry transfers among the Clearing Agency Participants and receive
        and transmit payments on the Trust Preferred Securities to such Clearing
        Agency Participants.

        (b) A single Common Securities Certificate representing the Common
Securities shall be issued to the Depositor in the form of a definitive Common
Securities Certificate.

    SECTION 5.12. NOTICES TO CLEARING AGENCY.

        To the extent that a notice or other communication to the Holders is
required under this Trust Agreement, for so long as Trust Preferred Securities
are represented by a Book-Entry Trust Preferred Securities Certificates, the
Administrative Trustees and the Issuer Trustee shall give all such notices and
communications specified herein to be given to the Clearing Agency, and shall
have no obligations to the Owners.

    SECTION 5.13. DEFINITIVE TRUST PREFERRED SECURITIES CERTIFICATES.

        If (a) the Depositor advises the Issuer Trustees in writing that the
Clearing Agency is no longer willing or able to properly discharge its
responsibilities with respect to the Trust Preferred Securities Certificates,
and the Depositor is unable to locate a qualified successor, (b) the Depositor
at its option advises the Issuer Trustees in writing that it elects to terminate
the book-entry system through the Clearing Agency or (c) after the occurrence of
a Debenture Event of Default, Owners of Trust Preferred Securities Certificates
representing beneficial interests aggregating at least a majority of the
Liquidation Amount advise the Administrative Trustees in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interest of the Owners of Trust Preferred Securities Certificates, then
the Administrative Trustees shall notify the other Issuer Trustees and the
Clearing Agency, and the Clearing Agency, in accordance with its customary rules
and procedures, shall notify all Clearing Agency Participants for whom it holds
Trust Preferred Securities of the occurrence of any such event and of the
availability of the Definitive Trust Preferred Securities Certificates to Owners
of such class or classes, as applicable, requesting the same. Upon surrender to
the Administrative Trustees of the typewritten Trust Preferred Securities
Certificate or Certificates representing the


                                       25
<PAGE>   30

Book-Entry Trust Preferred Securities Certificates by the Clearing Agency,
accompanied by registration instructions, the Administrative Trustees, or any
one of them, shall execute the Definitive Trust Preferred Securities
Certificates in accordance with the instructions of the Clearing Agency. Neither
the Securities Registrar nor the Trustees shall be liable for any delay in
delivery of such instructions and may conclusively rely on, and shall be
protected in relying on, such instructions. Upon the issuance of Definitive
Trust Preferred Securities Certificates, the Issuer Trustees shall recognize the
Holders of the Definitive Trust Preferred Securities Certificates as holders of
Trust Securities. The Definitive Trust Preferred Securities Certificates shall
be typewritten, printed, lithographed or engraved or may be produced in any
other manner as is reasonably acceptable to the Administrative Trustees that
meets the requirements of any stock exchange or automated quotation system on
which the Trust Preferred Securities are then listed or approved for trading, as
evidenced by the execution thereof by the Administrative Trustees or any one of
them.

    SECTION 5.14. RIGHTS OF HOLDERS; WAIVERS OF PAST DEFAULTS.

        (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Holders shall not have any right or title therein other than the undivided
beneficial interest in the assets of the Issuer Trust conferred by their Trust
Securities and they shall have no right to call for any partition or division of
property, profits or rights of the Issuer Trust except as described below. The
Trust Securities shall be personal property giving only the rights specifically
set forth therein and in this Trust Agreement. The Trust Securities shall have
no preemptive or similar rights and when issued and delivered to Holders against
payment of the purchase price therefor will be fully paid and nonassessable by
the Issuer Trust. The Holders of the Trust Securities, in their capacities as
such, shall be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.

        (b) For so long as any Trust Preferred Securities remain Outstanding,
if, upon a Debenture Event of Default, the Debenture Trustee fails or the
holders of not less than 25% in principal amount of the outstanding Debentures
fail to declare the principal of all of the Debentures to be immediately due and
payable, the Holders of at least 25% in Liquidation Amount of the Trust
Preferred Securities then Outstanding shall have the right to make such
declaration by a notice in writing to the Property Trustee, the Depositor and
the Debenture Trustee.

        At any time after a declaration of acceleration with respect to the
Debentures has been made and before a judgment or decree for payment of the
money due has been obtained by the Debenture Trustee as in the Indenture
provided, if the Property Trustee fails to annul any such declaration and waive
such default, the Holders of at least a Majority in Liquidation Amount of the
Trust Preferred Securities, by written notice to the Property Trustee, the
Depositor and the Debenture Trustee, may rescind and annul such declaration and
its consequences if:

            (i) the Depositor has paid or deposited with the Debenture Trustee a
        sum sufficient to pay


                                       26
<PAGE>   31

                (A) all overdue installments of interest on all of the
            Debentures,

                (B) any accrued Additional Interest on all of the Debentures,

                (C) the principal of (and premium, if any, on) any Debentures
            that have become due otherwise than by such declaration of
            acceleration and interest and Additional Interest thereon at the
            rate borne by the Debentures, and

                (D) all sums paid or advanced by the Debenture Trustee under the
            Indenture and the reasonable compensation, expenses, disbursements
            and advances of the Debenture Trustee and the Property Trustee,
            their agents and counsel; and

            (ii) all Events of Default with respect to the Debentures, other
        than the non-payment of the principal of the Debentures that has become
        due solely by such acceleration, have been cured or waived as provided
        in Section 513 of the Indenture.

        The Holders of at least a Majority in Liquidation Amount of the Trust
Preferred Securities may, on behalf of the Holders of all the Trust Preferred
Securities, waive any past default under the Indenture, except a default in the
payment of principal or interest (unless such default has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration has been deposited with the Debenture Trustee) or
a default in respect of a covenant or provision that under the Indenture cannot
be modified or amended without the consent of the holder of each outstanding
Debenture. No such rescission shall affect any subsequent default or impair any
right consequent thereon.

        Upon receipt by the Property Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, by Holders of any part of the
Trust Preferred Securities a record date shall be established for determining
Holders of Outstanding Trust Preferred Securities entitled to join in such
notice, which record date shall be at the close of business on the day the
Property Trustee receives such notice. The Holders on such record date, or their
duly designated proxies, and only such Persons, shall be entitled to join in
such notice, whether or not such Holders remain Holders after such record date;
provided that, unless such declaration of acceleration, or rescission and
annulment, as the case may be, shall have become effective by virtue of the
requisite percentage having joined in such notice prior to the day that is 90
days after such record date, such notice of declaration of acceleration, or
rescission and annulment, as the case may be, shall automatically and without
further action by any Holder be canceled and of no further effect. Nothing in
this paragraph shall prevent a Holder, or a proxy of a Holder, from giving,
after expiration of such 90-day period, a new written notice of declaration of
acceleration, or rescission and annulment thereof, as the case may be, that is
identical to a written notice that has been canceled pursuant to the proviso to
the preceding sentence, in which event a new record date shall be established
pursuant to the provisions of this Section 5.14(b).

        (c) For so long as any Trust Preferred Securities remain Outstanding, to
the fullest extent permitted by law and subject to the terms of this Trust
Agreement and the Indenture, upon a default in the payment of any installment of
interest (including Additional Interest) on any Debenture when due and the
continuance of such default for a period of 30 days (subject to the


                                       27
<PAGE>   32

deferral of any due date resulting from an Extension Period (as defined in the
Indenture) or a default in the payment of principal of any Debentures when due,
any Holder of Trust Preferred Securities shall have the right to institute a
proceeding directly against the Depositor, pursuant to Section 5.08 of the
Indenture, for enforcement of payment to such Holder of any amounts payable in
respect of Debentures having an aggregate principal amount equal to the
aggregate Liquidation Amount of the Trust Preferred Securities of such Holder (a
"Direct Action"). Except as set forth in Section 5.14(b) and this Section
5.14(c), the Holders of Trust Preferred Securities shall have no right to
exercise directly any right or remedy available to the holders of, or in respect
of, the Debentures.

        (d) Except as otherwise provided in paragraphs (a), (b) and (c) of this
Section 5.14, the Holders of at least a Majority in Liquidation Amount of the
Trust Preferred Securities may, on behalf of the Holders of all the Trust
Preferred Securities, waive any past default or Event of Default and its
consequences. Upon such waiver, any such default or Event of Default shall cease
to exist, and any default or Event of Default arising there from shall be deemed
to have been cured, for every purpose of this Trust Agreement, but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent thereon.

    SECTION 5.15. CUSIP NUMBERS.

        The Administrative Trustees in issuing the Trust Preferred Securities
may use "CUSIP" numbers (if then generally in use), and, if so, the Property
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Trust Preferred
Securities or as contained in any notice of a redemption and that reliance may
be placed only on the other identification numbers printed on the Trust
Preferred Securities, and any such redemption shall not be affected by any
defect in or omission of such numbers. The Administrative Trustees will promptly
notify the Property Trustee of any change in the CUSIP numbers.

                        ACTS OF HOLDERS; MEETINGS; VOTING

    SECTION 6.1. LIMITATIONS ON VOTING RIGHTS.

        (a) Except as expressly provided in this Trust Agreement and in the
Indenture and as otherwise required by law, no Holder of Trust Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Issuer Trust or the obligations
of the parties hereto, nor shall anything herein set forth, or contained in the
terms of the Trust Securities Certificates, be construed so as to constitute the
Holders from time to time as partners or members of an association.

        (b) So long as any Debentures are held by the Property Trustee on behalf
of the Issuer Trust, the Issuer Trustees shall not (i) direct the time, method
and place of conducting any proceeding for any remedy available to the Debenture
Trustee, or execute any trust or power conferred on the Debenture Trustee with
respect to the Debentures, (ii) waive any past default that may be waived under
Section 513 of the Indenture, (iii) exercise any right to rescind or


                                       28
<PAGE>   33

annul a declaration that the principal of all the Debentures shall be due and
payable, or (iv) consent to any amendment, modification or termination of the
Indenture or the Debentures, where such consent shall be required, without, in
each case, obtaining the prior approval of the Holders of at least a Majority in
Liquidation Amount of the Trust Preferred Securities, provided, however, that
where a consent under the Indenture would require the consent of each holder of
Debentures affected thereby, no such consent shall be given by the Property
Trustee without the prior written consent of each Holder of Trust Preferred
Securities. The Property Trustee shall not revoke any action previously
authorized or approved by a vote of the Holders of the Trust Preferred
Securities, except by a subsequent vote of the Holders of the Trust Preferred
Securities. The Property Trustee shall notify all Holders of the Trust Preferred
Securities of any notice of default received with respect to the Debentures. In
addition to obtaining the foregoing approvals of the Holders of the Trust
Preferred Securities, prior to taking any of the foregoing actions, the Issuer
Trustees shall, at the expense of the Depositor, obtain an Opinion of Counsel
experienced in such matters to the effect that such action shall not cause the
Issuer Trust to be taxable as a corporation or classified as other than a
grantor trust for United States Federal income tax purposes.

        (c) If any proposed amendment to the Trust Agreement provides for, or
the Issuer Trustees otherwise propose to effect, (i) any action that would
adversely affect in any material respect the powers, preferences or special
rights of the Trust Preferred Securities, whether by way of amendment to the
Trust Agreement or otherwise, or (ii) the dissolution and winding-up of the
Issuer Trust, other than pursuant to the terms of this Trust Agreement, then the
Holders of Outstanding Trust Preferred Securities as a class will be entitled to
vote on such amendment or proposal and such amendment or proposal shall not be
effective except with the approval of the Holders of at least a Majority in
Liquidation Amount of the Trust Preferred Securities. Notwithstanding any other
provision of this Trust Agreement, no amendment to this Trust Agreement may be
made if, as a result of such amendment, it would cause the Issuer Trust to be
taxable as a corporation or classified as other than a grantor trust for United
States Federal income tax purposes.

    SECTION 6.2. NOTICE OF MEETINGS.

        Notice of all meetings of the Holders of the Trust Preferred Securities,
stating the time, place and purpose of the meeting, shall be given by the
Property Trustee pursuant to Section 10.8 to each Holder of Trust Preferred
Securities, at such Holder's registered address, at least 15 days and not more
than 90 days before the meeting. At any such meeting, any business properly
before the meeting may be so considered whether or not stated in the notice of
the meeting. Any adjourned meeting may be held as adjourned without further
notice.

    SECTION 6.3. MEETINGS OF HOLDERS OF THE TRUST PREFERRED SECURITIES.

        No annual meeting of Holders is required to be held. The Property
Trustee, however, shall call a meeting of the Holders of the Trust Preferred
Securities to vote on any matter upon the written request of the Holders of at
least 25% in aggregate Liquidation Amount of the Outstanding Trust Preferred
Securities and the Administrative Trustees or the Property Trustee may, at any
time in their discretion, call a meeting of the Holders of the Trust Preferred
Securities to vote on any matters as to which such Holders are entitled to vote.


                                       29
<PAGE>   34

        The Holders of at least a Majority in Liquidation Amount of the Trust
Preferred Securities, present in person or by proxy, shall constitute a quorum
at any meeting of the Holders of the Trust Preferred Securities.

        If a quorum is present at a meeting, an affirmative vote by the Holders
present, in person or by proxy, holding Trust Preferred Securities representing
at least a Majority in aggregate Liquidation Amount of the Trust Preferred
Securities held by the Holders present, either in person or by proxy, at such
meeting shall constitute the action of the Holders of the Trust Preferred
Securities, unless this Trust Agreement requires a greater number of affirmative
votes.

    SECTION 6.4. VOTING RIGHTS.

        Holders shall be entitled to one vote for each $1,000 of Liquidation
Amount represented by their Outstanding Trust Securities in respect of any
matter as to which such Holders are entitled to vote.

    SECTION 6.5. PROXIES, ETC.

        At any meeting of Holders, any Holder entitled to vote thereat may vote
by proxy, provided that no proxy shall be voted at any meeting unless it shall
have been placed on file with the Property Trustee, or with such other officer
or agent of the Issuer Trust as the Property Trustee may direct, for
verification prior to the time at which such vote shall be taken. Pursuant to a
resolution of the Property Trustee, proxies may be solicited in the name of the
Property Trustee or one or more officers of the Property Trustee. Only Holders
of record shall be entitled to vote. When Trust Securities are held jointly by
several persons, any one of them may vote at any meeting in person or by proxy
in respect of such Trust Securities, but if more than one of them shall be
present at such meeting in person or by proxy, and such joint owners or their
proxies so present disagree as to any vote to be cast, such vote shall not be
received in respect of such Trust Securities. A proxy purporting to be executed
by or on behalf of a Holder shall be deemed valid unless challenged at or prior
to its exercise, and the burden of proving invalidity shall rest on the
challenger. No proxy shall be valid more than three years after its date of
execution.

    SECTION 6.6. HOLDER ACTION BY WRITTEN CONSENT.

        Any action that may be taken by Holders at a meeting may be taken
without a meeting and without prior notice if Holders holding at least a
Majority in Liquidation Amount of all Trust Preferred Securities entitled to
vote in respect of such action (or such larger proportion thereof as shall be
required by any other provision of this Trust Agreement) shall consent to the
action in writing.

    SECTION 6.7. RECORD DATE FOR VOTING AND OTHER PURPOSES.

        For the purposes of determining the Holders who are entitled to notice
of and to vote at any meeting or by written consent, or to participate in any
distribution on the Trust Securities in respect of which a record date is not
otherwise provided for in this Trust Agreement, or for the purpose of any other
action, the Administrative Trustees may from time to time fix a date, not more
than 90 days prior to the date of any meeting of Holders or the payment of a
Distribution or


                                       30
<PAGE>   35

other action, as the case may be, as a record date for the determination of the
identity of the Holders of record for such purposes.

    SECTION 6.8. ACTS OF HOLDERS.

        Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Trust Agreement to be given, made
or taken by Holders may be embodied in and evidenced by one or more instruments
of substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing; and, except as otherwise expressly provided herein,
such action shall become effective when such instrument or instruments are
delivered to the Property Trustee. Such instrument or instruments (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments. Proof of
execution of any such instrument or of a writing appointing any such agent shall
be sufficient for any purpose of this Trust Agreement and (subject to Section
8.1) conclusive in favor of the Issuer Trustees, if made in the manner provided
in this Section.

        The fact and date of the execution by any Person of any such instrument
or writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof. Where such execution is by
a signer acting in a capacity other than his individual capacity, such
certificate or affidavit shall also constitute sufficient proof of his
authority. The fact and date of the execution of any such instrument or writing,
or the authority of the Person executing the same, may also be proved in any
other manner that any Issuer Trustee receiving the same deems sufficient.

        The ownership of Trust Securities shall be proved by the Securities
Register.

        Any request, demand, authorization, direction, notice, consent, waiver
or other Act of the Holder of any Trust Security shall bind every future Holder
of the same Trust Security and the Holder of every Trust Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Issuer
Trustees, or the Issuer Trust in reliance thereon, whether or not notation of
such action is made upon such Trust Security.

        Without limiting the foregoing, a Holder entitled hereunder to take any
action hereunder with regard to any particular Trust Security may do so with
regard to all or any part of the Liquidation Amount of such Trust Security or by
one or more duly appointed agents each of which may do so pursuant to such
appointment with regard to all or any part of such Liquidation Amount.

        If any dispute shall arise between the Holders and the Issuer Trustees
or among the Holders or the Issuer Trustees with respect to the authenticity,
validity or binding nature of any request, demand, authorization, direction,
consent, waiver or other Act of such Holder or Issuer Trustee under this Article
VI, then the determination of such matter by the Property Trustee shall be
conclusive with respect to such matter.

    SECTION 6.9. INSPECTION OF RECORDS.

        Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Issuer Trust shall be open to inspection by Holders
during normal business hours for any purpose reasonably related to such Holder's
interest as a Holder.

    SECTION 7.2. REPRESENTATIONS AND WARRANTIES OF DEPOSITOR.

        The Depositor hereby represents and warrants for the benefit of the
Holders that:

        (a) the Trust Securities Certificates issued at the Time of Delivery on
behalf of the Issuer Trust have been duly authorized and will have been duly and
validly executed, issued and delivered by the Issuer Trustees pursuant to the
terms and provisions of, and in accordance with the requirements of, this Trust
Agreement, and the Holders will be, as of such date, entitled to the benefits of
this Trust Agreement; and

        (b) there are no taxes, fees or other governmental charges payable by

                                    ARTICLE 8
                               THE ISSUER TRUSTEES

    SECTION 8.1. CERTAIN DUTIES AND RESPONSIBILITIES.

        (a) The duties and responsibilities of the Issuer Trustees shall be as
provided by this Trust Agreement, subject to Section 10.10 hereof.
Notwithstanding the foregoing, but subject to Section 8.1(c), no provision of
this Trust Agreement shall require any of the Issuer Trustees to expend or risk
its or their own funds or otherwise incur any financial liability in the
performance of any of its or their duties hereunder, or in the exercise of any
of its or their rights or powers, if it or they shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it. Whether or not therein
expressly so provided, every provision of this Trust Agreement relating to the
conduct or


                                       33
<PAGE>   38

affecting the liability of or affording protection to the Issuer Trustees shall
be subject to the provisions of this Section 8.1. Nothing in this Trust
Agreement shall be construed to release an Administrative Trustee from liability
for his or her own negligent action, its own negligent failure to act, or his or
her own willful misconduct. To the extent that, at law or in equity, an
Administrative Trustee has duties and liabilities relating to the Issuer Trust
or to the Holders, such Administrative Trustee shall not be liable to the Issuer
Trust or to any Holder for such Administrative Trustee's good faith reliance on
the provisions of this Trust Agreement. The provisions of this Trust Agreement,
to the extent that they restrict the duties and liabilities of the
Administrative Trustees otherwise existing at law or in equity, are agreed by
the Depositor and the Holders to replace such other duties and liabilities of
the Administrative Trustees.

        (b) All payments made by the Property Trustee or a Paying Agent in
respect of the Trust Securities shall be made only from the revenue and proceeds
from the Trust Property and only to the extent that there shall be sufficient
revenue or proceeds from the Trust Property to enable the Property Trustee or a
Paying Agent to make payments in accordance with the terms hereof. Each Holder,
by its acceptance of a Trust Security, agrees that it will look solely to the
revenue and proceeds from the Trust Property to the extent legally available for
distribution to it as herein provided and that the Issuer Trustees are not
personally liable to such Holder for any amount distributable in respect of any
Trust Security or for any other liability in respect of any Trust Security. This
Section 8.1(b) does not limit the liability of the Issuer Trustees expressly set
forth elsewhere in this Trust Agreement or, in the case of the Property Trustee,
in the Trust Indenture Act.

        (c) If an Event of Default has occurred and is continuing, the Property
Trustee shall enforce this Trust Agreement for the benefit of the Holders.

        (d) The Property Trustee, before the occurrence of any Event of Default
and after the curing of all Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Trust Agreement (including pursuant to Section 10.10), and no implied covenants
shall be read into this Trust Agreement against the Property Trustee. If an
Event of Default has occurred (that has not been cured or waived pursuant to
Section 5.14, the Property Trustee shall exercise such of the rights and powers
vested in it by this Trust Agreement, and use the same degree of care and skill
in its exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

            (i) prior to the occurrence of any Event of Default and after the
        curing or waiving of all such Events of Default that may have occurred:

                (A) the duties and obligations of the Property Trustee shall be
            determined solely by the express provisions of this Trust Agreement
            (including pursuant to Section 10.10), and the Property Trustee
            shall not be liable except for the performance of such duties and
            obligations as are specifically set forth in this Trust Agreement
            (including pursuant to Section 10.10); and


                                       34
<PAGE>   39

                (B) in the absence of bad faith on the part of the Property
            Trustee, the Property Trustee may conclusively rely, as to the truth
            of the statements and the correctness of the opinions expressed
            therein, upon any certificates or opinions furnished to the Property
            Trustee and conforming to the requirements of this Trust Agreement;
            but in the case of any such certificates or opinions that by any
            provision hereof or of the Trust Indenture Act are specifically
            required to be furnished to the Property Trustee, the Property
            Trustee shall be under a duty to examine the same to determine
            whether or not they conform to the requirements of this Trust
            Agreement;

            (ii) the Property Trustee shall not be liable for any error of
        judgment made in good faith by an authorized officer of the Property
        Trustee, unless it shall be proved that the Property Trustee was
        negligent in ascertaining the pertinent facts;

            (iii) the Property 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 at least a Majority in Liquidation
        Amount of the Trust Preferred Securities relating to the time, method
        and place of conducting any proceeding for any remedy available to the
        Property Trustee, or exercising any trust or power conferred upon the
        Property Trustee under this Trust Agreement;

            (iv) the Property Trustee's sole duty with respect to the custody,
        safe keeping and physical preservation of the Debentures and the Payment
        Account shall be to deal with such Property in a similar manner as the
        Property Trustee deals with similar property for its own account,
        subject to the protections and limitations on liability afforded to the
        Property Trustee under this Trust Agreement and the Trust Indenture Act;

            (v) the Property Trustee shall not be liable for any interest on any
        money received by it except as it may otherwise agree with the
        Depositor; and money held by the Property Trustee need not be segregated
        from other funds held by it except in relation to the Payment Account
        maintained by the Property Trustee pursuant to Section 3.1 and except to
        the extent otherwise required by law;

            (vi) the Property Trustee shall not be responsible for monitoring
        the compliance by the Administrative Trustees or the Depositor with
        their respective duties under this Trust Agreement, nor shall the
        Property Trustee be liable for the default or misconduct of any other
        Issuer Trustee, the Administrative Trustees or the Depositor; and

            (vii) subject to Section 8.1(c), no provision of this Trust
        Agreement shall require the Property 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 the Property Trustee shall have reasonable grounds for believing that
        the repayment of such funds or liability is not reasonably assured to it
        under the terms of this Trust Agreement or adequate indemnity against
        such risk or liability is not reasonably assured to it.


                                       35
<PAGE>   40

        (f) The Administrative Trustees shall not be responsible for monitoring
the compliance by the other Issuer Trustees or the Depositor with their
respective duties under this Trust Agreement, nor shall either Administrative
Trustee be liable for the default or misconduct of any other Issuer Trustee or
the Depositor.

    SECTION 8.2. CERTAIN NOTICES.

        Within ten days after the occurrence of any Event of Default actually
known to the Property Trustee, the Property Trustee shall transmit, in the
manner and to the extent provided in Section 10.8, notice of such Event of
Default to the Holders and the Administrative Trustees, unless such Event of
Default shall have been cured or waived.

        Within five Business Days after the receipt of notice of the Depositor's
exercise of its right to defer the payment of interest on the Debentures
pursuant to the Indenture, the Property Trustee shall transmit, in the manner
and to the extent provided in Section 10.8, notice of such exercise to the
Holders and the Administrative Trustees, unless such exercise shall have been
revoked.

        The Property Trustee shall not be deemed to have knowledge of any Event

Responsible Officer of the Property Trustee charged with the administration of
this Trust Agreement shall have obtained actual knowledge of such Event of
Default.

Trustee or Trustees, and such successor RelevantTrustee shall comply with the
applicable requirements of Section 8.11. If no successor Relevant Trustee shall
have been so appointed by the Holders of the Capital Securities and accepted
appointment in the manner required by Section 8.11, any Holder, on behalf of
such Holder and all others similarly situated, or any other Issuer Trustee, may
petition any court of competent jurisdiction for the appointment of a successor
Relevant Trustee.

        The Property Trustee shall give notice of each resignation and each
removal of an Issuer Trustee and each appointment of a successor Issuer Trustee
to all Holders in the manner provided in Section 10.8 and shall give notice to
the Depositor and to the Administrative Trustees. Each notice shall include the
name of the successor Relevant Trustee and the address of its Corporate Trust
Office if it is the Property Trustee.

        Notwithstanding the foregoing or any other provision of this Trust
Agreement, if any Delaware Trustee who is a natural person dies or becomes, in
the opinion of the Holders of the Common Securities, incompetent or
incapacitated, the vacancy created by such death, incompetence or incapacity may
be filled by the Holders of the Common Securities following the procedures
regarding expenses and charges set forth above (with the successor being a
Person who satisfies the eligibility requirement for the Delaware Trustee set
forth in Section 8.7).

        In case of the appointment hereunder of a successor Issuer Trustee, the
retiring Issuer Trustee (if requested by the Depositor) and each successor
Issuer Trustee with respect to the Trust Securities shall execute and deliver an
amendment hereto wherein each successor Issuer Trustee shall accept such

provide for or facilitate the administration of the Issuer Trust by more than
one Issuer Trustee, it being understood that nothing herein or in such amendment
shall constitute such Issuer Trustees co-trustees and upon the execution and
delivery of such amendment the resignation or removal of the retiring Issuer
Trustee shall become effective to the extent provided therein and each such
successor Issuer Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Issuer Trustee, other than the filing of an amendment to the Certificate of
Trust to the extent required under the Delaware Business Trust Act; but, on
request of the Issuer Trust or any successor Issuer Trustee such retiring Issuer
Trustee shall duly assign, transfer and deliver to such successor Issuer Trustee
all Trust Property, all proceeds thereof and money held by such retiring Issuer
Trustee hereunder with respect to the Trust Securities and the Issuer Trust.

        Upon request of any such successor Issuer Trustee, the Issuer Trust
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Issuer Trustee all such rights, powers and
trusts referred to in the first or second preceding paragraph, as the case may
be.

        No successor Issuer Trustee shall accept its appointment unless at the
time of such acceptance such successor Issuer Trustee shall be qualified and
eligible under this Article VIII.

    SECTION 8.12. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

        Any Person into which the Property Trustee or the Delaware Trustee may

resulting from any merger, conversion or consolidation to which such Relevant
Trustee shall be a party, or any Person, succeeding to all or substantially all
the corporate trust business of such Relevant Trustee, shall be the successor of
such Relevant Trustee hereunder, provided that such Person shall be otherwise
qualified and eligible under this Article VIII, without the execution or filing
of any paper or any further act on the part of any of the parties hereto, other
than the filing of an amendment to the Certificate of Trust to the extent
required under the Delaware Business Trust Act.

    SECTION 8.13. PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR OR ISSUER
                  TRUST.

        If and when the Property Trustee shall be or become a creditor of the

Securities), the Property Trustee shall be subject to the provisions of the

Property Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Property Trustee, its agents and counsel, and
any other amounts due the Property Trustee.

        Nothing herein contained shall be deemed to authorize the Property
Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement adjustment or compensation affecting the
Trust Securities or the rights of any Holder thereof or to authorize the
Property Trustee to vote in respect of the claim of any Holder in any such

                       DISSOLUTION, LIQUIDATION AND MERGER

    SECTION 9.1. DISSOLUTION UPON EXPIRATION DATE.

        Unless earlier dissolved, the Issuer Trust shall automatically dissolve
(the "Expiration Date"), and its affairs be wound up, on
________________________, following the distribution of the Trust Property in
accordance with Section 9.4.

    SECTION 9.2. EARLY DISSOLUTION.

        The first to occur of any of the following events is an "Early
Dissolution Event", the occurrence of which shall cause a dissolution of the
Trust:

        (a) the occurrence of a Depositor Bankruptcy Event in respect of, or the
dissolution or liquidation of, the Depositor, in its capacity as the Holder of
the Common Securities, unless the Depositor shall transfer the Common Securities
as provided by Section 5.10, in which case this provision shall refer instead to
any such successor Holder of the Common Securities;

        (b) the written direction to the Property Trustee from all of the
Holders of the Common Securities at any time to dissolve the Issuer Trust and to
distribute the Debentures to Holders in exchange for the Trust Preferred
Securities (which direction is optional and wholly within the discretion of the
Holders of the Common Securities);

    SECTION 9.4. LIQUIDATION.

        (a) If an Early Dissolution Event specified in clause (a), (b) or (d) of
Section 9.2 occurs or upon the Expiration Date, the Issuer Trust shall be
liquidated by the Property Trustee as expeditiously as the Property Trustee
determines to be possible by distributing, after satisfaction of liabilities to
creditors of the Issuer Trust as provided by applicable law, to each Holder a
Like Amount of Debentures, subject to Section 9.4(d). Notice of liquidation
shall be given by the Property Trustee by first-class mail, postage prepaid,
mailed not less than 30 nor more than 60 days prior to the Liquidation Date to
each Holder of Trust Securities at such Holder's address appearing in the
Securities Register. All such notices of liquidation shall:

            (i) state the CUSIP Number of the Trust Securities;

            (ii) state the Liquidation Date;

            (iii) state that from and after the Liquidation Date, the Trust
        Securities will no longer be deemed to be Outstanding and any Trust
        Securities Certificates not surrendered for exchange will be deemed to
        represent a Like Amount of Debentures; and

            (iv) provide such information with respect to the mechanics by which
        Holders may exchange Trust Securities Certificates for Debentures, or if
        Section 9.4(d) applies, receive a Liquidation Distribution, as the
        Property Trustee (after consultation with the Administrative
        Trustees)shall deem appropriate.

        (b) Except where Section 9.2(c) or 9.4(d) applies, in order to effect
the liquidation of the Issuer Trust and distribution of the Debentures to
Holders, the Property Trustee, either itself acting as exchange agent or through
the appointment of a separate exchange agent, shall establish a record date for
such distribution (which shall be not more than 30 days prior to the Liquidation
Date) and, establish such procedures as it shall deem appropriate to effect the
distribution of Debentures in exchange for the Outstanding Trust Securities
Certificates.

        (c) Except where Section 9.2(c) or 9.4(d) applies, after the Liquidation
Date, (i) the Trust Securities will no longer be deemed to be Outstanding, (ii)
certificates representing a Like Amount of Debentures will be issued to Holders
of Trust Securities Certificates, upon surrender of such Certificates to the
exchange agent for exchange, (iii) any Trust Securities Certificates not so
surrendered for exchange will be deemed to represent a Like Amount of Debentures
bearing accrued and unpaid interest in an amount equal to the accumulated and
unpaid Distributions on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal will be made to Holders of Trust Securities
Certificates with respect to such Debentures) and (iv) all rights of Holders
holding Trust Securities will cease, except the right of such Holders to receive
Debentures upon surrender of Trust Securities Certificates.

        (d) If, notwithstanding the other provisions of this Section 9.4,
whether because of an order for dissolution entered by a court of competent
jurisdiction or otherwise, distribution of the Debentures in the manner provided
herein is determined by the Property Trustee not to be practical, or if an Early
Dissolution Event specified in clause (c) of Section 9.2 occurs, the Trust
Property shall be liquidated, and the Issuer Trust's affairs wound-up, by the
Property Trustee in


                                       47
<PAGE>   52

such manner as the Property Trustee determines. In such event, Holders will be
entitled to receive out of the assets of the Issuer Trust available for
distribution to Holders, after satisfaction of liabilities to creditors of the
Issuer Trust as provided by applicable law, an amount equal to the Liquidation
Amount per Trust Security plus accumulated and unpaid Distributions thereon to
the date of payment (such amount being the "Liquidation Distribution"). If the
Liquidation Distribution can be paid only in part because the Issuer Trust has
insufficient assets available to pay in full the aggregate Liquidation
Distribution, then the amounts payable by the Issuer Trust on the Trust
Securities shall be paid on a pro rata basis (based upon Liquidation Amounts).
The Holders of the Common Securities will be entitled to receive Liquidation
Distributions upon any such winding-up pro rata (determined as aforesaid) with
Holders of Trust Preferred Securities.

    SECTION 9.5. MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF
                 ISSUER TRUST.

        The Issuer Trust may not merge with or into, consolidate, amalgamate, or
be replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any Person, except pursuant to Section 9.4 or
this Section 9.5. At the request of the Holders of the Common Securities, with
the consent of the Holders of at least a Majority in Liquidation Amount of the
Trust Preferred Securities, and without the consent of the Issuer Trustees, the
Issuer Trust may merge with or into, consolidate, amalgamate, or be replaced by
or convey, transfer or lease its properties and assets substantially as an
entirety to a trust organized as such under the laws of any state; provided,
that (i) such successor entity either (a) expressly assumes all of the
obligations of the Issuer Trust with respect to the Trust Preferred Securities,
or (b) substitutes for the Trust Preferred Securities other securities having
substantially the same terms as the Trust Preferred Securities (the "Successor
Securities") so long as the Successor Securities have the same priority as the
Trust Preferred Securities with respect to distributions and payments upon
liquidation, redemption and otherwise, (ii) a trustee of such successor entity
possessing the same powers and duties as the Property Trustee is appointed to
hold the Debentures, (iii) such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease does not cause the Trust Preferred
Securities (including any Successor Securities) to be downgraded by any
nationally recognized statistical rating organization, (iv) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the holders of the
Trust Preferred Securities (including any Successor Securities) in any material
respect, (v) such successor entity has a purpose substantially identical to that
of the Issuer Trust, (vi) prior to such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, the Property Trustee has received an
Opinion of Counsel to the effect that (a) such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not adversely
affect the rights, preferences and privileges of the Holders of the Trust
Preferred Securities (including any Successor Securities) in any material
respect, and (b) following such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease, neither the Issuer Trust nor such
successor entity will be required to register as an "investment company" under
the Investment Company Act, and (vii) the Depositor or its permitted transferee
owns all of the common securities of such successor entity and guarantees the
obligations of such successor entity under the Successor Securities at least to
the extent provided by the Guarantee Agreement. Notwithstanding the foregoing,
the Issuer Trust shall not, except with the consent of Holders of all of the
Trust Preferred Securities, consolidate, amalgamate, merge with or into, or be
replaced by or convey, transfer or lease its properties and assets substantially
as an entirety to


                                       48
<PAGE>   53

any other entity or permit any other entity to consolidate, amalgamate, merge
with or into, or replace it if such consolidation, amalgamation, merger,
replacement, conveyance, transfer or lease would cause the Issuer Trust or the
successor entity to be taxable as a corporation or classified as other than a
grantor trust for United States Federal income tax purposes.

    SECTION 10.1. LIMITATION OF RIGHTS OF HOLDERS.

        Except as set forth in Section 9.2, the death or incapacity of any
Person having an interest, beneficial or otherwise, in Trust Securities shall
not operate to terminate this Trust Agreement, nor dissolve, annul or terminate
the Trust, nor entitle the legal representatives or heirs of such Person or any
Holder for such person, to claim an accounting, take any action or bring any
proceeding in any court for a partition or winding up of the arrangements
contemplated hereby, nor otherwise affect the rights, obligations and
liabilities of the parties hereto or any of them.

Trustees, (i) to cure any ambiguity, correct or supplement any provision herein
that may be inconsistent with any other provision herein, or to make any other
provisions with respect to matters or questions arising under this Trust
Agreement, which shall not be inconsistent with the other provisions of this
Trust Agreement, or (ii) to modify, eliminate or add to any provisions of this
Trust Agreement to such extent as shall be necessary to ensure that the Issuer
Trust will not be taxable as a corporation or classified as other than a grantor
trust for United States Federal income tax purposes at all times that any Trust
Securities are outstanding or to ensure that the Issuer Trust will not be
required to register as an "investment company" under the Investment Company
Act; provided, however, that in the case of either clause (i) or (ii), such
action shall not adversely affect in any material respect the interests of any
Holder. Any such amendment will become effective when notice thereof is given to
the holders of the Trust Preferred Securities.

        (b) Except as provided in Section 10.2(c), any provision of this Trust
Agreement may be amended by the Administrative Trustees and the Holders of all
of the Common Securities and with (i) the consent of Holders of at least a
Majority in Liquidation Amount of the Trust Preferred Securities, and (ii)
receipt by the Issuer Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees or the
Administrative Trustees in accordance with such amendment will not affect the
Trust's status as a grantor trust or cause the Issuer Trust to be taxable as a
corporation or as other than a grantor trust for United States Federal income
tax purposes or affect the Issuer Trust's exemption from status as an
"investment company" under the Investment Company Act.

        (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Holder, this Trust Agreement may
not be amended to

otherwise adversely affect the amount of any Distribution required to be made in
respect of the Trust Securities as of a specified date, or (ii) restrict the
right of a Holder to institute suit for the enforcement of any such payment on
or after such date; and notwithstanding any other provision herein, without the
unanimous consent of the Holders, this paragraph (c) of this Section 10.2 may
not be amended.

        (d) Notwithstanding any other provisions of this Trust Agreement, no
Issuer Trustee shall enter into or consent to any amendment to this Trust
Agreement that would cause the Issuer Trust to fail or cease to qualify for the
exemption from status as an "investment company" under the Investment Company
Act or to be taxable as a corporation or to be classified as other than a
grantor trust for United States Federal income tax purposes.

        (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor and the Administrative Trustees, this Trust
Agreement may not be amended in a manner that imposes any additional obligation
on the Depositor or the Administrative Trustees.

without the consent of the Property Trustee or the Delaware Trustee, this Trust
Agreement may not be amended in a manner that imposes any additional obligation

Trustee.

        (g) In the event that any amendment to this Trust Agreement is made, the
Administrative Trustees or the Property Trustee shall promptly provide to the
Depositor a copy of such amendment.

        (h) Neither the Property Trustee nor the Delaware Trustee shall be
required to enter into any amendment to this Trust Agreement that affects its
own rights, duties or immunities under this Trust Agreement. The Property
Trustee shall be entitled to receive an Opinion of Counsel and an Officers'
Certificate stating that any amendment to this Trust Agreement is in compliance
with this Trust Agreement.

    SECTION 10.3. SEPARABILITY.

        In case any provision in this Trust Agreement or in the Trust Securities
Certificates shall be invalid, illegal or unenforceable, the validity, legality

Trustee. Such notice, demand or other communication to or upon the Issuer Trust,
the Property Trustee or the Administrative Trustees shall be deemed to have been
sufficiently given or made only upon actual receipt of the writing by the Issuer
Trust, the Property Trustee or such Administrative Trustee.

    SECTION 10.9. AGREEMENT NOT TO PETITION.

        Each of the Issuer Trustees and the Depositor agree for the benefit of
the Holders that, until at least one year and one day after the Issuer Trust has
been dissolved in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Issuer Trust under any bankruptcy,
insolvency, reorganization or other similar law (including the United States
Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in the
commencement of any proceeding against the Issuer Trust under any Bankruptcy
Law. If the Depositor takes action in violation of this Section 10.9, the
Property Trustee agrees, for the benefit of Holders, that at the expense of the
Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Issuer
Trust or the commencement of such action and raise the defense that the
Depositor has agreed in writing not to take such action and should be stopped
and precluded therefrom and such other defenses, if any, as counsel for the
Issuer Trustee or the Issuer Trust may assert.

    SECTION 10.10. TRUST INDENTURE ACT; CONFLICT WITH TRUST INDENTURE ACT.

        (a) Except as otherwise expressly provided herein, the Trust Indenture
Act shall apply as a matter of contract to this Trust Agreement for purposes of
interpretation, construction and defining the rights and obligations hereunder,
and this Trust Agreement, the Depositor and the Property Trustee shall be deemed
for all purposes hereof to be subject to and governed by the Trust Indenture Act
to the same extent as would be the case if this Trust Agreement were qualified
under that Act on the date hereof. Except as otherwise expressly provided
herein, if and to the extent that any provision of this Trust Agreement limits,
qualifies or conflicts with the duties imposed by Sections 310 to 317,
inclusive, of the Trust Indenture Act, such imposed duties shall control.

        (b) The Property Trustee shall be the only Issuer Trustee that is a
trustee for the purposes of the Trust Indenture Act.

        (c) The application of the Trust Indenture Act to this Trust Agreement
shall not affect the nature of the Trust Securities as equity securities
representing undivided beneficial interests in the assets of the Issuer Trust.

    SECTION 10.11. ACCEPTANCE OF TERMS OF TRUST AGREEMENT, GUARANTEE AGREEMENT
                   AND INDENTURE.

        THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST THEREIN
BY OR ON BEHALF OF A HOLDER OR ANY BENEFICIAL OWNER, WITHOUT ANY SIGNATURE OR
FURTHER MANIFESTATION OF ASSENT, SHALL CONSTITUTE THE UNCONDITIONAL ACCEPTANCE
BY THE HOLDER AND ALL OTHERS HAVING A BENEFICIAL INTEREST IN SUCH TRUST SECURITY
OF ALL THE

ISSUER TRUST, SUCH HOLDER AND SUCH OTHERS THAT THE TERMS AND PROVISIONS OF THIS
TRUST AGREEMENT SHALL BE BINDING, OPERATIVE AND EFFECTIVE AS BETWEEN THE ISSUER
TRUST AND SUCH HOLDER AND SUCH OTHERS.

    SECTION 10.12. COUNTERPARTS.

        This Trust Agreement may contain more than one counterpart of the
signature page and this Trust Agreement may be executed by the affixing of the
signature of each of the Trustees to one of such counterpart signature pages.
All of such counterpart signature pages shall be read as though one, and they

single signature page.
