         that Distributions thereon shall cease to accumulate on and after said
         date, except as provided in Section 402(d); and

         surrendered for the payment of the Redemption Price.

         (c) The Trust Securities redeemed on each Redemption Date shall be

Payment Account for the payment of such Redemption Price.

         (d) If the Property Trustee gives a notice of redemption in respect of

such Securities shall cease to be Outstanding, (iii) the Clearing Agency for the

held by the Clearing Agency for the Trust Preferred Securities or its nominee as
specified in clause (iii) above will be deemed to represent Debentures having a
principal amount equal to the stated Liquidation Amount of the Trust Securities
represented thereby and bearing accrued and unpaid interest in an amount equal
to the accumulated and unpaid Distributions on such Trust Securities until such
certificates are presented to the Securities Registrar for transfer or

                                      -18-

is not a Business Day, then payment of the Redemption Price payable on such date
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) except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day (and without any reduction of interest
or any other payment in respect of any such acceleration), 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 Trust or by the
Depositor pursuant to the Guarantee, Distributions on such Trust Securities
shall continue to accumulate, at the then applicable rate, from the Redemption
Date originally established by the Trust for such Trust Securities to the date
such Redemption Price is actually paid, in which case the actual payment date
shall be the date fixed for redemption for purposes of calculating the
Redemption Price.

         (e) Payment of the Redemption Price on the Trust Securities shall be
made to the record holders thereof as they appear on the Securities Register for
the Trust Securities on the relevant record date, which shall be the date 15
days prior to the relevant Redemption Date.

Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Trust Preferred Securities. The particular Trust Preferred Securities to be
redeemed shall be selected 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, by such method (including, without limitation,
by lot) as the Property Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to $10 or an
integral multiple of $10 in excess thereof) of the Liquidation Amount of Trust
Preferred Securities of a denomination larger than $10. 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 Liquidation Amount of
Trust Preferred Securities which has been or is to be redeemed.

Securities and the Trust Preferred Securities based on the Liquidation Amount of
the Trust Securities; provided, however, that if on any Distribution Date or
Redemption Date any Event of Default resulting from a Debenture Event of Default
shall have occurred and be continuing, no payment of any Distribution (including
Additional Amounts, if applicable) on, or Redemption Price of, any Common
Security, and no other payment on account

                                      -19-

be made unless payment in full in cash of all accumulated and unpaid
Distributions (including Additional Amounts, if applicable) on all Outstanding
Trust Preferred Securities for all Distribution periods terminating on or prior
thereto, or in the case of payment of the Redemption Price the full amount of
such Redemption Price on all Outstanding Trust Preferred Securities then called
for redemption, shall have been made or provided for, and all funds immediately
available to the Property Trustee shall first be applied to the payment in full
in cash of all Distributions (including Additional Amounts, if applicable) on,
or the Redemption Price of, Trust Preferred Securities then due and payable.

         (b) In the case of the occurrence of any Event of Default resulting
from a Debenture Event of Default, the Holder of Common Securities, the
Depositor, shall be deemed to have waived any 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 shall have been
cured, waived or otherwise eliminated. Until any such Event of Default under
this Trust Agreement with respect to the Trust Preferred Securities shall 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 the
Holder of the Common Securities, and only the Holders of the Trust Preferred

behalf.

Agency, such Distributions shall be made to the Clearing Agency in immediately

Distribution Dates. Payments in respect of the Common Securities shall be made
in such manner as shall be mutually agreed between the Property Trustee and the
Holder of the Common Securities.

(c) hereof.

                          TRUST SECURITIES CERTIFICATES

SECTION 501.      INITIAL OWNERSHIP.

         Upon the creation of the Trust and the contribution by the Depositor
pursuant to Section 203 and until the issuance of the Trust Securities, and at
any time during which no Trust Securities are outstanding, the Depositor shall
be the sole beneficial owner of the Trust.

SECTION 502.      THE TRUST SECURITIES CERTIFICATES.

         The Trust Preferred Securities Certificates shall be issued in minimum
denominations of $10 Liquidation Amount and integral multiples of $10 in excess
thereof, and the Common Securities Certificates shall be issued in denominations
of $10 Liquidation Amount and integral multiples thereof. The Trust Securities
Certificates shall be executed on behalf of the Trust by manual or facsimile
signature of at least one Administrative Trustee. Trust Securities Certificates
bearing the manual or facsimile signatures of individuals who were, at the time
when such signatures shall have been affixed, authorized to sign on behalf of
the Trust, shall be validly issued and entitled to the benefits of this Trust
Agreement, notwithstanding that such individuals

                                      -21-
<PAGE>   27

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 Securityholder, and shall be entitled to
the rights and subject to the obligations of a Securityholder hereunder, upon
due registration of such Trust Securities Certificate in such transferee's name
pursuant to Sections 504, 511 and 513.

SECTION 503.      EXECUTION, AUTHENTICATION AND DELIVERY OF TRUST
                  SECURITIES CERTIFICATES.

         (a) On the First Closing Date, and, if applicable the Second Closing
Date, the Administrative Trustees shall cause Trust Securities Certificates, in
an aggregate Liquidation Amount as provided in Sections 204 and 205, to be
executed on behalf of the Trust by at least one of the Administrative Trustees
and delivered to or upon the written order of the Depositor, signed by its Chief
Executive Officer, President, any Vice President, its Chief Financial Officer or
its Treasurer without further corporate action by the Depositor, in authorized
denominations, whereupon (and, in the case of Trust Preferred Securities
Certificates, upon the authentication thereof by the Property Trustee as
described in (b) below) the Trust Securities evidenced by such Trust Securities
Certificates shall, without further actions by the Trust or any other Person, be
duly and validly issued undivided beneficial interests in the assets of the
Trust and entitled to the benefits of this Trust Agreement.

         (b) A Trust Preferred Securities Certificate shall not be valid until
authenticated by the manual signature of an authorized signatory of the Property
Trustee. The signature shall be conclusive evidence that the Trust Preferred
Securities Certificate has been authenticated under this Trust Agreement. Each
Trust Preferred Security Certificate shall be dated the date of its
authentication.

         Upon the written order of the Trust signed by one of the Administrative
Trustees, the Property Trustee shall authenticate and make available for
delivery the Trust Preferred Securities Certificates.

         The Property Trustee may appoint an Authenticating Agent acceptable to
the Trust to authenticate the Trust Securities. An Authenticating Agent may
authenticate the Trust Securities whenever the Property Trustee may do so. Each
reference in this Trust Agreement to authentication by the Property Trustee
includes authentication by such agent. An Authenticating Agent has the same
rights as the Property Trustee to deal with the Company or the Trust.

SECTION 503A.           GLOBAL TRUST PREFERRED SECURITY.

         (a) Any Global Trust Preferred Security issued under this Trust
Agreement shall be registered in the name of the nominee of the Clearing Agency
and delivered to the Property Trustee as custodian therefor, or if requested by
DTC or an Administrative Trustee and accepted by DTC, held by DTC, and such
Global Trust Preferred Security shall constitute a single Trust Preferred
Security for all purposes of this Trust Agreement.

                                      -22-
<PAGE>   28

         (b) Notwithstanding any other provision in this Trust Agreement, no
Global Trust Preferred Security may be exchanged for Definitive Trust Preferred
Securities registered in the names of persons other than the Depositary or its
nominee unless (i) the Depositary notifies the Depositor and the Property
Trustee that it is unwilling or unable to continue as a depositary for such
Global Trust Preferred Securities and the Depositor is unable to locate a
qualified successor depositary within 90 days of receipt of such notice, (ii)
the Depositor executes and delivers to the Property Trustee and the Depository a
written order stating that it elects to terminate the book-entry system through
the Depositary or (iii) a Debenture Event of Default shall have occurred, and is
continuing.

         (c) If a Trust Preferred Security is to be exchanged in whole or in
part for a beneficial interest in a Global Trust Preferred Security, then either
(i) such Global Trust Preferred Security shall be so surrendered for exchange or
cancellation as provided in this Article V or (ii) the Liquidation amount
thereof shall be reduced or increased by an amount equal to the portion thereof
to be so exchanged or canceled, or equal to the Liquidation Amount of such other
Trust Preferred Securities to be so exchanged for a beneficial interest therein,
as the case may be, by means of an appropriate adjustment made on the records of
the Securities Registrar, whereupon the Property Trustee, in accordance with the
rules and procedures of the Depositary for such Global Trust Preferred Security
(the "Applicable Procedures"), shall instruct the Clearing Agency or its
authorized representative to make a corresponding adjustment to its records.
Upon any such surrender or adjustment of a Global Trust Preferred Security by or
on behalf of the Clearing Agency, accompanied by registration instructions, the
Administrative Trustees shall execute and the Property Trustee shall, subject to
Section 504(b) and as otherwise provided in this Article V, authenticate and
deliver any Definitive Trust Preferred Securities Certificates issuable in
exchange for such Global Trust Preferred Security (or any portion thereof) in
accordance with the instructions of the Clearing Agency. Neither the Securities
Registrar nor any of the Trustees shall be liable for any delay in delivery of
such instructions and may conclusively rely on, and shall be fully protected in
relying on, such instructions. Upon the issuance of the Definitive Trust
Preferred Securities, the Trustees shall recognize the holders of the Definitive
Trust Preferred Securities Certificates as Holders of the Trust Preferred
Securities. The Definitive Trust Preferred Securities Certificates shall be
printed, lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Administrative Trustees, as evidenced by the
execution thereof by the Administrative Trustees or any one of them.

         (d) Every Trust Preferred Security executed, authenticated and
delivered upon registration of transfer of, or in exchange for or in lieu of, a
Global Trust Preferred Security or any portion thereof, whether pursuant to this
Article V or otherwise, shall be executed, authenticated and delivered in the
form of, and shall be, a Global Trust Preferred Security, unless such Global
Trust Preferred Security is registered in the name of a Person other than the
Clearing Agency for such Global Trust Preferred Security or a nominee thereof.

         (e) The Clearing Agency or its nominee, as the registered owner of a
Global Trust Preferred Security, shall be considered the Holder of the Trust
Preferred Securities represented by such Global Trust Preferred Security for all
purposes under this Trust Agreement and the Trust Preferred Securities, and
owners of beneficial interests in such Global Trust Preferred Security shall
hold such interests pursuant to the Applicable Procedures and, except as
otherwise provided herein, shall not be entitled to receive physical delivery of
any such Trust Preferred Securities in definitive form and shall not be
considered the Holders thereof under this Trust Agreement. Accordingly, any such
owner's beneficial interest in the Global Trust Preferred Securities shall be
shown only on, and the transfer of such interest shall be effected only through,
records

                                      -23-
<PAGE>   29

maintained by the Clearing Agency or its nominee. Neither the Property Trustee,
the Securities Registrar nor Depositor shall have any liability in respect of
any transfers effected by the Clearing Agency.

         (f) (i) Neither the Depositor, the Trust nor any Trustee shall have any
responsibility or obligation to any beneficial owner of a Global Security, any
participant in the Depositary or other Person with respect to the accuracy of
the records of the Depositary or its nominee or of any participant thereof, with
respect to any ownership interest in the Trust Preferred Securities or with
respect to the delivery to any participant in the Depositary, beneficial owner
or other Person (other than the Depositary) of any notice (including any notice
of redemption) or the payment of any amount, under or with respect to such Trust
Preferred Securities. All notices and communications to be given to the Holders
and all payments to be made to Holders under the Trust Preferred Securities
shall be given or made only to or upon the order of the registered Holders
(which shall be the Depositary or its nominee in the case of a Global Security).
The rights of beneficial owners in any Global Security shall be exercised only
through the Depositary subject to the applicable rules and procedures of the
Depositary. The Property Trustee and Securities Registrar may conclusively rely
and shall be fully protected in relying upon information furnished by the
Depositary or any agent thereof with respect to its participants and any
beneficial owners.

         (ii) The Property Trustee and the Security Registrar shall have no
obligation or duty to monitor, determine or inquire as to the compliance with
any restrictions on transfer imposed under this Trust Agreement or under
applicable law with respect to any transfer of any interest in any Trust
Preferred Security (including any transfers between or among Depositary
participants or beneficial owners in any Global Security) other than to require
delivery of such certificates and other documentation or evidence as are
expressly required by, and to do so if and when expressly required by, the terms
of this Trust Agreement and to examine the same to determine substantial
compliance as to form with the express requirements hereof.

SECTION 504.      REGISTRATION OF TRANSFER AND EXCHANGE OF TRUST
                  PREFERRED SECURITIES CERTIFICATES.

         (a) The Trust shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 508, a register or registers for the purpose of
registering Trust Securities Certificates and, subject to the provisions of
Section 503A, transfers and exchanges of Trust Securities Certificates (herein
referred to as the "Securities Register") in which the 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 510 in the case of the Common Securities Certificates) and registration
of transfers and exchanges of Trust Preferred Securities Certificates as herein
provided. The Property Trustee is hereby appointed the initial Securities
Registrar, and in such capacity shall keep the Securities Register at its
Corporate Trust Office.

         (b) Subject to the provisions of Section 503A, upon surrender for
registration of transfer of any Trust Preferred Securities Certificate at the
office or agency maintained pursuant to Section 508, the Administrative Trustees
or any one of them shall execute and deliver to the Property Trustee, and the
Property Trustee shall authenticate and make available for delivery, in the name
of the designated transferee or transferees, one or more new Trust Preferred
Securities Certificates in authorized denominations of a like aggregate
Liquidation Amount dated the date 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.
At the option of a Holder thereof, 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 508.

         (c) Every Trust Preferred Securities Certificate presented or
surrendered for registration of transfer or exchange, subject to the provisions
of Section 503A, shall be accompanied by a written instrument of transfer in
form satisfactory to the Property 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 the Property Trustee
in accordance with its customary practice. The Trust shall not be required to
(i) issue, register the transfer of, or exchange any Trust Preferred Securities
during a period beginning at the opening of business 15 calendar days before the
date of mailing of a notice of redemption of any Trust Preferred

                                      -24-
<PAGE>   30

Securities called for redemption and ending at the close of business on the day
of such mailing; or (ii) register the transfer of or exchange any Trust
Preferred Securities so selected for redemption, in whole or in part, except the
unredeemed portion of any such Trust Preferred Securities being redeemed in
part.

         (d) No service charge shall be made for any registration of transfer or
exchange of Trust Preferred Securities, subject to the provisions of Section
503A, 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.

         (e) Trust Preferred Securities may only be transferred, in whole or in
part, in accordance with the terms and conditions set forth in this Trust
Agreement. Any transfer or purported transfer of any Trust Preferred Security
not made in accordance with this Trust Agreement shall be null and void. A Trust
Preferred Security that is not a Global Trust Preferred Security may be
transferred, in whole or in part, to a Person who takes delivery in the form of
another Trust Preferred Security that is not a Global Trust Preferred Security
as provided in Section 504(a). A beneficial interest in a Global Trust Preferred
Security may be exchanged for a Trust Preferred Security that is not a Global
Trust Preferred Security only as provided in Section 503A.

SECTION 505.      MUTILATED, DESTROYED, LOST OR STOLEN TRUST
                  SECURITIES CERTIFICATES.

         If (a) any mutilated Trust Securities Certificate shall be surrendered
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
that such Trust Securities Certificate shall have been acquired by a bona fide
purchaser, or a protected purchaser, the Administrative Trustees, or any one of
them, on behalf of the Trust shall execute and make available for delivery, and
in the case of a Trust Preferred Securities Certificate, the Property Trustee
shall authenticate, in exchange for or in lieu of any such mutilated, destroyed,
lost or stolen Trust Securities Certificate, a new Trust Securities Certificate
of like class, tenor and denomination. In connection with the issuance of any
new Trust Securities Certificate under this Section 505, 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 505 shall constitute conclusive evidence of an undivided beneficial
interest in the assets of the Trust, as if originally issued, whether or not the
lost, stolen or destroyed Trust Securities Certificate shall be found at any
time.

SECTION 506.      PERSONS DEEMED SECURITYHOLDERS.

         The Trust, Trustees, Paying Agent and Securities Registrar shall treat
the Person in whose name any Trust Securities shall be registered in the
Securities Register as the owner of such Trust

                                      -25-
<PAGE>   31

Securities for the purpose of receiving Distributions and for all other purposes
whatsoever, and neither the Trustees nor the Securities Registrar shall be bound
by any notice to the contrary.

SECTION 507.      ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND
                  ADDRESSES.

         At any time when the Property Trustee is not also acting as the
Securities Registrar, the Administrative Trustees or the Depositor shall furnish
or cause to be furnished to the Property Trustee (a) within five Business Days
of each record date, a list, in such form as the Property Trustee may reasonably
require, of the names and addresses of the Securityholders as of the most recent
record date; and (b) promptly after receipt by any Administrative Trustee or the
Depositor of a request therefor from the Property Trustee in order to enable the
Property Trustee to discharge its obligations under this Trust Agreement, in
each case to the extent such information is in the possession or control of the
Administrative Trustees or the Depositor and is not identical to a previously
supplied list or has not otherwise been received by the Property Trustee in its
capacity as Securities Registrar. The rights of Securityholders to communicate
with other Securityholders with respect to their rights under this Trust
Agreement or under the Trust Securities, and the corresponding rights of the
Property Trustee shall be as provided in the Trust Indenture Act. Each Holder,
by receiving and holding a Trust Securities Certificate, and each beneficial
owner of a Trust Preferred Security shall be deemed to have agreed not to hold
the Depositor, the Property 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 508.      MAINTENANCE OF OFFICE OR AGENCY.

         The Trust shall maintain, or cause to be maintained, in The City of New
York, New York or Wilmington, Delaware or other location designated by the
Administrative Trustees, 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 Trustees in
respect of the Trust Securities Certificates may be served. The Administrative
Trustees initially designate the Corporate Trust Office of the Property Trustee,
as the principal office for such purposes. The Administrative Trustees shall
give prompt written notice to the Depositor, the Property Trustee and the
Securityholders of any change in the location of the Securities Register or any
such office or agency.

SECTION 509.      APPOINTMENT OF PAYING AGENT.

         The Paying Agent shall make Distributions to Securityholders 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 for the purpose
of making the Distributions referred to above. The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust Agreement in any material respect. The Paying Agent
shall initially be the Property

                                      -26-
<PAGE>   32

Trustee, and any co-paying agent chosen by the Property Trustee, and acceptable
to the Administrative Trustees and the Depositor. Any Person acting as Paying
Agent shall be permitted to resign as Paying Agent upon 30 days written notice
to the Administrative Trustees, the Property Trustee and the Depositor. In the
event that the Property Trustee shall no longer be the Paying Agent or a
successor Paying Agent shall resign or its authority to act be revoked, the
Administrative Trustees shall appoint a successor that is acceptable to the
Property Trustee and the Depositor to act as Paying Agent (which shall be a bank
or trust company). The Administrative Trustees shall cause such successor Paying
Agent or any additional Paying Agent appointed by the Administrative Trustees to
execute and deliver to the Trustees an instrument in which such successor Paying
Agent or additional Paying Agent shall agree with the Trustees that as Paying
Agent, such successor Paying Agent or additional Paying Agent shall hold all
sums, if any, held by it for payment to the Securityholders in trust for the
benefit of the Securityholders entitled thereto until such sums shall be paid to
such Securityholders. 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 801, 803 and 806 shall apply to the Property Trustee also in its
role as Paying Agent, for so long as the Property Trustee 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 510.      OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

         On the First Closing Date, and, if applicable, the Second Closing Date,
the Depositor shall acquire and retain beneficial and record ownership of the
Common Securities. To the fullest extent permitted by law, any attempted
transfer of the Common Securities (other than a transfer in connection with a
merger or consolidation of the Depositor into another corporation pursuant to
Section 12.1 of the Indenture) shall be void. The Administrative Trustees shall
cause each Common Securities Certificate issued to the Depositor to contain a
legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE."

SECTION 511.      TRUST SECURITIES CERTIFICATES.

         (a) Upon their original issuance, Trust Preferred Securities
Certificates shall be issued in the form of one or more fully registered Global
Trust Preferred Securities Certificates which will be deposited with or on
behalf of the Clearing Agency and registered in the name of the Clearing
Agency's nominee and held by the Property Trustee as custodian therefor or if
requested by DTC or by an Administrative Trustee and accepted by DTC, held by
DTC. Unless and until it is exchangeable in whole or in part for the Trust
Preferred Securities in definitive form, a global security may not be
transferred except as a whole by the Clearing Agency to a nominee of the
Clearing Agency or by a nominee of the Clearing Agency to the Clearing Agency or
another nominee of the Clearing Agency or by the Clearing Agency or any such
nominee to a successor of such Clearing Agency or a nominee of such successor.

         (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.

<PAGE>   33

SECTION 512.      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 Global Trust Preferred Securities Certificate, all such
notices and communications specified herein shall be given to the Clearing
Agency, and neither the Trust nor any trustee shall have any obligations to
provide notice to the owners of the beneficial interest in the Global Trust
Preferred Securities.

SECTION 513.      RIGHTS OF SECURITYHOLDERS.

         (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 209, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the 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 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 issuance of
Trust Preferred Securities is not subject to, and the Trust Preferred Securities
shall have no, preemptive or similar rights to subscribe for additional Trust
Preferred Securities. When issued and delivered to Holders of the Trust
Preferred Securities against payment of the purchase price therefor, the Trust
Preferred Securities shall be fully paid and nonassessable interests in the
Trust. The Holders of the Trust Preferred 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 such right by a notice in
writing to the Depositor and the Debenture Trustee; and upon any such
declaration such principal amount of and the accrued interest on all of the
Debentures shall become immediately due and payable, provided that the payment
of principal and interest on such Debentures shall remain subordinated to the
extent provided in the Indenture.

         (c) For so long as any Trust Preferred Securities remain outstanding,
upon a Debenture Event of Default arising from the failure to pay interest or
principal on the Debentures, the Holders of any Trust Preferred Securities then
Outstanding shall, to the fullest extent permitted by law, have the right to
directly institute proceedings for enforcement of payment to such Holders of
principal of or interest on the Debentures having a principal amount equal to
the Liquidation Amount of the Trust Preferred Securities of such Holders.

                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

SECTION 601.      LIMITATIONS ON VOTING RIGHTS.

         (a) Except as otherwise provided in this Section 601, in Sections 512,
810 and 1002 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 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 Securityholders 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 Trust, the Trustees shall not (i) direct the time, method and
place of conducting any proceeding for any remedy available to the Debenture
Trustee, or executing any trust or power conferred on the Debenture Trustee with
respect to such Debentures; (ii) waive any past default which is waivable under
Article VII of the Indenture; (iii) exercise any right to rescind or 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 all Outstanding Trust Preferred Securities; provided,
however, that where a consent under the Indenture would require the consent of
each holder of outstanding Debentures affected thereby, no such consent shall be
given by the Property Trustee without the prior written consent of each Holder
of Outstanding Trust Preferred Securities. The Trustees shall not revoke any
action previously authorized or approved by a vote of the Holders of the
Outstanding Trust Preferred Securities, except by a subsequent vote of the
Holders of the Outstanding Trust Preferred Securities. The Property Trustee
shall notify each Holder of the Outstanding Trust Preferred Securities of any
notice of default received from the Debenture Trustee 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 Trustees shall, at the expense of the Depositor, obtain an Opinion of
Counsel experienced in such matters to the effect that the Trust shall continue
to be classified as a grantor trust and not as an association taxable as a
corporation for United States federal income tax purposes on account of such
action.

         (c) If any proposed amendment to the Trust Agreement provides for, or
the 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, winding-up or termination of the Trust,
other than pursuant to the terms of this Trust Agreement, then the Holders of
Outstanding Trust Preferred Securities as a class shall 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 Outstanding Trust Preferred Securities. No amendment to this Trust
Agreement may be made if, as a result of such

                                      -29-
<PAGE>   35

amendment, the Trust would cease to be classified as a grantor trust or would be
classified as an association taxable as a corporation for United States federal
income tax purposes.

SECTION 602.      NOTICE OF MEETINGS.

         Notice of all meetings of the Holders of Trust Preferred Securities,
stating the time, place and purpose of the meeting, shall be given by the
Property Trustee pursuant to Section 1008 to each Holder of Trust Preferred
Securities, at his 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 603.      MEETINGS OF TRUST PREFERRED SECURITYHOLDERS.

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

         (b) Holders of more than 50% of the Liquidation Amount of Outstanding
Trust Preferred Securities, present in person or by proxy, shall constitute a
quorum at any meeting of such Securityholders.

         (c) If a quorum is present at a meeting, an affirmative vote by Holders
of Trust Preferred Securities present, in person or by proxy, holding not less
than a majority of the Liquidation Amount of the Trust Preferred Securities held
by the Holders of Trust Preferred Securities of record present, either in person
or by proxy, at such meeting shall constitute the action of the Securityholders,
unless this Trust Agreement requires a greater number of affirmative votes.

SECTION 604.      VOTING RIGHTS.

         Securityholders shall be entitled to one vote for each $10 of
Liquidation Amount represented by their Trust Securities (with any fractional
multiple thereof rounded up or down as the case may be to the closest integral
multiple) in respect of any matter as to which such Securityholders are entitled
to vote.

SECTION 605.      PROXIES, ETC.

         At any meeting of Securityholders, any Securityholder 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 Administrative Trustees, or
with such other officer or agent of the Trust as the

                                      -30-
<PAGE>   36

Administrative Trustees may direct, for verification prior to the time at which
such vote shall be taken. 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 Securityholder 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 606.      SECURITYHOLDER ACTION BY WRITTEN CONSENT.

         Any action which may be taken by Securityholders at a meeting may be
taken without a meeting if Securityholders holding not less than a majority of
all outstanding Trust Securities (based upon their aggregate Liquidation Amount)
entitled to vote in respect of such action (or such larger proportion thereof as
shall be required by any express provision of this Trust Agreement) shall
consent to the action in writing.

SECTION 607.      RECORD DATE FOR VOTING AND OTHER PURPOSES.

         For the purposes of determining the Securityholders 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 or the Property Trustee may from time
to time fix a date, not more than 90 days prior to the date of any meeting of
Securityholders or the payment of Distribution or other action, as the case may
be, as a record date for the determination of the identity of the
Securityholders of record for such purposes.

SECTION 608.      ACTS OF SECURITYHOLDERS.

         (a) 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 Securityholders may be embodied in and evidenced by one
or more instruments of substantially similar tenor signed by such
Securityholders 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 an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders
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 801) conclusive in favor
of the Trustees, if made in the manner provided in this Section 608.

         (b) 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

                                      -31-
<PAGE>   37

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 which any Trustee
receiving the same deems sufficient.

         (c) The ownership of Trust Preferred Securities shall be proved by the
Securities Register.

         (d) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Securityholder of any Trust Security shall bind every
future Securityholder of the same Trust Security and the Securityholder 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 Trustees or the Trust in reliance thereon, whether or not
notation of such action is made upon such Trust Security.

         (e) Without limiting the foregoing, a Securityholder 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.

         (f) A Securityholder may institute a legal proceeding directly against
the Depositor under the Guarantee to enforce its rights under the Guarantee
without first instituting a legal proceeding against the Guarantee Trustee (as
defined in the Guarantee), the Trust or any other Person.

SECTION 609.      INSPECTION OF RECORDS.

         Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Trust shall be open to inspection at the principal
executive office of the Trust (as indicated in Section 202) by Holders of the
Trust Securities during normal business hours for any purpose reasonably related
to such Holder's interest as a record holder.

                                  ARTICLE VIII
                                    TRUSTEES

SECTION 801.      CERTAIN DUTIES AND RESPONSIBILITIES.

         (a) The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee, by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Trust Agreement shall require any Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it 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. No
Administrative Trustee nor the Delaware Trustee shall be liable for its act or
omissions hereunder except as a result of its own gross negligence or willful
misconduct. The Property Trustee's liability shall be determined under this
Trust Agreement and the Trust Indenture Act. Whether or not therein expressly so
provided, every provision of this Trust Agreement relating to the conduct or
affecting the liability of or affording protection to the Trustees shall be
subject to the provisions of this Section 801. To the extent that, at law or in
equity, a Trustee has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to the Securityholders, such Trustee shall not
be liable to the Trust or to any Securityholder for

                                      -35-
<PAGE>   41

such Trustee's good faith reliance on the provisions of this Trust Agreement. To
the extent that the provisions of this Trust Agreement restrict the duties and
liabilities of the Trustees otherwise existing at law or in equity, such
provisions are agreed by the Depositor and the Securityholders to replace such
other duties and liabilities of the Delaware 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
Securityholder, by its acceptance of a Trust Security, agrees that it shall 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 Trustees are
not personally liable to it for any amount distributable in respect of any Trust
Security or for any other liability in respect of any Trust Security. This
Section 801(b) does not limit the liability of the Trustees expressly set forth
elsewhere in this Trust Agreement or, in the case of the Property Trustee, in
the Trust Indenture Act.

         (c) 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 1010)
                  and no implied covenants shall be read into this Trust
                  Agreement against the Property Trustee, 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 1010); and

                           (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 on their face
                  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 on their face 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 not less than a
         majority in Liquidation Amount of the Trust 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;

                                      -36-
<PAGE>   42

                  (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; and

                  (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
         301 and except to the extent otherwise required by law.

         (d) 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 negligence, default or misconduct of the Administrative Trustees or the
Depositor.

SECTION 802.      CERTAIN NOTICES.

         (a) Within five Business Days after a Responsible Officer of the
Property Trustee has actual knowledge of the occurrence of any Event of Default,
the Property Trustee shall transmit, in the manner and to the extent provided in
Section 1008, notice of such Event of Default to the Securityholders, the
Administrative Trustees and the Depositor, unless such Event of Default shall
have been cured or waived. For purposes of this Section 802 the term "Event of
Default" means any event that is, or after notice or lapse of time or both would
become, an Event of Default.

         (b) The Administrative Trustees shall transmit, to the Securityholders
in the manner and to the extent provided in Section 1008, notice of the
Depositor's election to begin or further extend an Extended Interest Payment
Period on the Debentures (unless such election shall have been revoked) within
the time specified for transmitting such notice to the holders of the Debentures
pursuant to the Indenture as originally executed.

SECTION 803.      CERTAIN RIGHTS OF PROPERTY TRUSTEE.

         Subject to the provisions of Section 801:

         (a) the Property Trustee may rely and shall be protected in acting or
refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate, statement, instrument, opinion, report,
notice, request, consent, order, appraisal, bond, debenture, note, other
evidence of indebtedness or other paper or document believed by it to be genuine
and to have been signed or presented by the proper party or parties;

                                      -37-
<PAGE>   43

         (b) if (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action; or
(ii) in construing any of the provisions of this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with other provisions contained
herein; or (iii) the Property Trustee is unsure of the application of any
provision of this Trust Agreement, or determines that it desires clarification
or guidance regarding its performance under this Trust Agreement, then, except
as to any matter as to which the Trust Preferred Securityholders are
specifically entitled to vote under the terms of this Trust Agreement, the
Property Trustee shall deliver a notice to the Depositor requesting written
instructions of the Depositor as to the course of action to be taken and the
Property Trustee shall take such action, or refrain from taking such action, as
the Property Trustee shall be instructed in writing to take, or to refrain from
taking, by the Depositor; provided, however, that until the Property Trustee has
received such instructions from the Depositor after it has delivered such
notice, it may, but shall be under no duty to, take or refrain from taking such
action with respect to matters specified in its request as it shall, in good
faith, deem advisable and to be in the best interests of the Securityholders;

         (c) any direction or act of the Depositor or the Administrative
Trustees contemplated by this Trust Agreement shall be sufficiently evidenced by
an Officers' Certificate;

         (d) whenever in the administration of this Trust Agreement, the
Property Trustee shall deem it desirable that a matter be established before
undertaking, suffering or omitting any action hereunder, the Property Trustee
(unless other evidence is herein specifically prescribed) may, in the absence of
bad faith on its part, request and conclusively rely upon an Officer's
Certificate which, upon receipt of such request, shall be promptly delivered by
the Depositor or the Administrative Trustees;

         (e) the Property Trustee shall have no duty to see to any recording,
filing or registration of any instrument (including any financing or
continuation statement, or any filing under tax or securities laws) or any
rerecording, refiling or reregistration thereof;

         (f) the Property Trustee may consult with counsel of its choice (which
counsel may be counsel to the Depositor or any of its Affiliates, and may
include its employees) and the advice of such counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in reliance thereon and, in accordance with
such advice; the Property Trustee shall have the right at any time to seek
instructions concerning the administration of this Trust Agreement from any
court of competent jurisdiction;

         (g) the Property Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the Securityholders pursuant to this Trust Agreement, unless
such Securityholders shall have offered to the Property Trustee security or
indemnity reasonably satisfactory to it against the costs, expenses and
liabilities which might be incurred by it in compliance with such request or
direction;

                                      -38-
<PAGE>   44

         (h) the Property 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,

negligence of such person;

         (j) whenever in the administration of this Trust Agreement the Property
Trustee shall deem it desirable to receive instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request instructions from the Holders of the Trust Securities
which instructions may only be given by the Holders of the same proportion in
Liquidation Amount of the Trust Securities as would be entitled to direct the
Property Trustee under the terms of the Trust Securities in respect of such
remedy, right or action; (ii) may refrain from enforcing such remedy or right or
taking such other action until such instructions are received; and (iii) shall
be protected in conclusively relying on or acting in accordance with such
instructions;

         (k) except as otherwise expressly provided by this Trust Agreement, the
Property Trustee shall not be under any obligation to take any action that is
discretionary under the provisions of this Trust Agreement. No provision of this
Trust Agreement shall be deemed to impose any duty or obligation on the Property
Trustee to perform any act or acts or exercise any right, power, duty or
obligation conferred or imposed on it, in any jurisdiction in which it shall be
illegal, or in which the Property Trustee shall be unqualified or incompetent in
accordance with applicable law, to perform any such act or acts, or to exercise
any such right, power, duty or obligation. No permissive power or authority
available to the Property Trustee shall be construed to be a duty;

constitute expenses of administration under any bankruptcy law or law relating

Event of Default unless a Responsible Officer of the Property Trustee has
obtained actual knowledge of such event or the Property Trustee has received
written notice of such event from any Holder or the Depositor;

such purpose join with the Property Trustee in the execution, delivery and
performance of all instruments and agreements necessary or proper to appoint,
one or more Persons approved by the Property Trustee either to act as

such property, in either case with such powers as may be provided in the
instrument of appointment, and to vest in such Person or Persons in the capacity
aforesaid, any property, title, right or power deemed necessary or desirable,
subject to the other provisions of this Section 809. If the Depositor does not

co-trustee or separate trustee appointed pursuant to this Section 809 shall
either be (i) a natural person who is at least 21 years of age and a resident of
the United States; or (ii) a legal entity with its principal place of business

co-trustee or separate trustee such property, title, right, or power, any and
all such instruments shall, on request, be executed, acknowledged, and delivered

         required to be deposited or pledged with, the Trustees specified
         hereunder, shall be exercised, solely by such Trustees and not by such
         co-trustee or separate trustee.

         property covered by such appointment shall be conferred or imposed upon
         and exercised or performed by the Property Trustee or by the Property
         Trustee and such co-trustee or separate trustee jointly, as shall be
         provided in the instrument appointing such co-trustee or separate
         trustee, except to the extent that under any law of any jurisdiction in
         which any particular act is to be performed, the Property Trustee shall
         be incompetent or unqualified to perform such act, in which event such
         rights, powers, duties and obligations shall be exercised and performed
         by such co-trustee or separate trustee.

                  (iii) The Property Trustee at any time, by an instrument in
         writing executed by it, with the written concurrence of the Depositor,
         may accept the resignation of or remove any co-trustee or separate
         trustee appointed under this Section 809, and, in case a Debenture
         Event of Default has occurred and is continuing, the Property Trustee
         shall have the power to accept the resignation of, or remove, any such
         co-trustee or separate trustee without the concurrence of the
         Depositor. Upon the written request of the Property Trustee, the
         Depositor shall join with the Property Trustee in the execution,
         delivery and performance of all instruments and agreements necessary or
         proper to effectuate such resignation or removal. A successor to any
         co-trustee or separate trustee so resigned or removed may be appointed
         in the manner provided in this Section 809.

                  (iv) No co-trustee or separate trustee hereunder shall be
         personally liable by reason of any act or omission of the Property
         Trustee or any other trustee hereunder.

                  (v) The Property Trustee shall not be liable by reason of any
         act of a co-trustee or separate trustee.

                  (vi) Any Act of Holders delivered to the Property Trustee
         shall be deemed to have been delivered to each such co-trustee and
         separate trustee.

SECTION 810.      RESIGNATION AND REMOVAL; APPOINTMENT OF
                  SUCCESSOR.

         (a) No resignation or removal of any Trustee (the "Relevant Trustee")
and no appointment of a successor Trustee pursuant to this Article VIII shall
become effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 811.

         (b) Subject to the immediately preceding paragraph, the Relevant
Trustee may resign at any time with respect to the Trust Securities and the
Trust by giving written notice thereof to the Securityholders. If the instrument
of acceptance by the successor Trustee required by Section 811 shall not have
been delivered to the Relevant Trustee within 30 days after the giving of such
notice of resignation, the Relevant Trustee may petition, at the expense of the
Depositor, any court of competent jurisdiction or the appointment of a successor
Relevant Trustee with respect to the Trust Securities and the Trust.

                                      -43-
<PAGE>   49

         (c) Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Holder of the
Common Securities. If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation
Amount of the Trust Preferred Securities, delivered to the Relevant Trustee (in
its individual capacity and on behalf of the Trust). An Administrative Trustee
may be removed by the Common Securityholder at any time.

         (d) If any Trustee shall resign, be removed or become incapable of
acting as Trustee, or if a vacancy shall occur in the office of any Trustee for
any cause, at a time when no Debenture Event of Default shall have occurred and
be continuing, the Holder of the Common Securities by Act of the such
Securityholder delivered to the retiring Trustee, shall promptly appoint a
successor Trustee or Trustees with respect to the Trust Securities and the
Trust, and the successor Trustee shall comply with the applicable requirements
of Section 811. If the Property Trustee or the Delaware Trustee shall resign, be
removed or become incapable of continuing to act as the Property Trustee or the
Delaware Trustee, as the case may be, at a time when a Debenture Event of
Default shall have occurred and is continuing, the Holders of Trust Preferred
Securities, by Act of the Securityholders of a majority in Liquidation Amount of
the Trust Preferred Securities then Outstanding delivered to the retiring
Relevant Trustee, shall promptly appoint a successor Relevant Trustee or
Trustees with respect to the Trust Securities and the Trust, and such successor
Trustee shall comply with the applicable requirements of Section 811. If an
Administrative Trustee shall resign, be removed or become incapable of acting as
Administrative Trustee, at a time when a Debenture Event of Default shall have
occurred and be continuing, the Holder of Common Securities, by Act of such
Securityholder delivered to an Administrative Trustee, shall promptly appoint a
successor Administrative Trustee or Administrative Trustees with respect to the
Trust Securities and the Trust, and such successor Administrative Trustee or
Administrative Trustees shall comply with the applicable requirements of Section
811. If no successor Relevant Trustee with respect to the Trust Securities and
the Trust shall have been so appointed by the Holder of Common Securities or the
Holders of Trust Preferred Securities and accepted appointment in the manner
required by Section 811, any Securityholder who has been a Securityholder of
Trust Securities on behalf of himself and all others similarly situated may
petition a court of competent jurisdiction for the appointment Trustee with
respect to the Trust Securities and the Trust.

         (e) The Property Trustee shall give notice of each resignation and each
removal of a Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 1008 and shall give notice to
the Depositor. 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.

         (f) Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of remaining

                                      -44-

Administrative Trustees if there are at least two of them; or (b) otherwise by
the Depositor (with the successor in each case being a Person who satisfies the
eligibility requirement for Administrative Trustees set forth in Section 807).

SECTION 811.      ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

         (a) In case of the appointment hereunder of a successor Relevant
Trustee with respect to the Trust Securities and the Trust, the retiring
Relevant Trustee, upon the payment in full to it of all amounts it is entitled
to under this Trust Agreement, including Section 806, and each successor
Relevant Trustee with respect to the Trust Securities shall execute and deliver
an instrument hereto wherein each successor Relevant Trustee shall accept such
appointment and which shall contain such provisions as shall be necessary or
desirable to transfer and confirm to, and to vest in, each successor Relevant
Trustee all the rights, powers, trusts and duties of the retiring Relevant
Trustee with respect to the Trust Securities and the Trust and upon the
execution and delivery of such instrument the resignation or removal of the
retiring Relevant Trustee shall become effective to the extent provided therein
and each such successor Relevant Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Relevant Trustee with respect to the Trust Securities and the
Trust; but, on request of the Trust or any successor Relevant Trustee such
retiring Relevant Trustee shall duly assign, transfer and deliver to such
successor Relevant Trustee all Trust Property, all proceeds thereof and money
held by such retiring Relevant Trustee hereunder with respect to the Trust
Securities and the Trust.

         (b) Upon request of any such successor Relevant Trustee, the Trust
shall execute any and all instruments for more fully and certainly vesting in
and confirming to such successor Relevant Trustee all such rights, powers and
trusts referred to in the immediately preceding paragraph, as the case may be.

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

SECTION 812.      MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
                  BUSINESS.

         Any Person into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee may be merged or converted or with which it may be
consolidated, or any Person 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 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.

become a creditor of the Depositor or the Trust (or any other obligor upon the
Debentures or the Trust Securities), the Property Trustee or the Delaware

         materially affects the Trust Securities.

         (b) In addition, the Property Trustee shall transmit to Securityholders

         (c) Except where Section 902(c) or 904(d) applies, after the
Liquidation Date, (i) the Trust Securities shall no longer be deemed to be
outstanding; (ii) certificates representing a Like Amount of Debentures shall be
issued to Holders of Trust Securities Certificates upon surrender of such
certificates to the Administrative Trustees or their agent for exchange; (iii)
the Depositor shall use its reasonable efforts to have the Debentures listed on
the American Stock Exchange or on such other securities exchange or other
organization as the Trust Preferred Securities are then listed or traded; (iv)
any Trust Securities Certificates not so surrendered for exchange shall be
deemed to represent a Like Amount of Debentures, accruing interest at the rate
provided for in the Debentures from the last Distribution Date on which a
Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal shall be made to Holders of Trust
Securities Certificates with respect to such Debentures); and (v) all rights of
Securityholders holding Trust Securities shall cease, except the right of such
Securityholders to receive Debentures upon surrender of Trust Securities
Certificates.

         (d) In the event that, notwithstanding the other provisions of this
Section 904, whether because of an order for dissolution of the Trust 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, the Trust Property shall be liquidated, and the Trust shall be
dissolved, wound-up or terminated, by the Property Trustee in such manner as the
Property Trustee determines. In such event, on the date of the dissolution,
winding-up or other termination of the Trust, Securityholders shall be entitled
to receive out of the assets of the Trust available for distribution to
Securityholders, after satisfaction of liabilities to creditors of the 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, upon any such
dissolution, winding-up or termination, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then, subject to the next succeeding
sentence, the amounts payable by the Trust on the Trust Securities shall be paid
on a pro rata basis (based upon Liquidation Amounts). The Holder of the Common
Securities shall be entitled to receive Liquidation Distributions upon any such
dissolution, winding-up or termination pro rata (determined as aforesaid) with
Holders of Trust Preferred Securities, except that, if a Debenture Event of
Default has occurred and is continuing, the Trust Preferred Securities shall
have a priority over the Common Securities. Following the dissolution of the
Trust and after completion of the winding up of the affairs of the Trust
pursuant to this Section 904(d), the Property Trustee shall file a Certificate
of Cancellation with the Delaware Secretary of State.

SECTION 905.      MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR
                  REPLACEMENTS OF THE TRUST.

         The 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 corporation or other Person, except pursuant
to this Section 905. At the request of the Depositor, with the consent of the
Administrative Trustees and without the consent of the Holders of the Trust
Preferred Securities, the Property Trustee or the Delaware Trustee, the Trust
may merge with or into, consolidate, amalgamate, 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
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 rank the same as the Trust Preferred Securities rank in
priority with respect to distributions and payments upon liquidation, redemption
and otherwise; (ii) the Depositor expressly appoints a trustee of such successor
entity possessing substantially the same powers and duties as the Property
Trustee as the holder of the Debentures; (iii) the Successor Securities are
listed or traded, or any Successor Securities shall be listed or traded upon
notification of issuance, on any national securities exchange or other
organization on which the Trust Preferred Securities are then listed, if any;
(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

                                      -50-
<PAGE>   56

Successor Securities) in any material respect; (v) such successor entity has a
purpose substantially identical to that of the Trust; (vi) prior to such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, the
Depositor 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 Trust nor such successor
entity shall be required to register as an "investment company" under the
Investment Company Act; and (vii) the Depositor 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. Notwithstanding the foregoing, the 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 any
other Person or permit any other Person to consolidate, amalgamate, merge with
or into, or replace it if such consolidation, amalgamation, merger or
replacement would cause the Trust or the successor entity to be classified as
other than a grantor trust for United States federal income tax purposes.

                                    ARTICLE X
                            MISCELLANEOUS PROVISIONS

SECTION 1001.           LIMITATION OF RIGHTS OF SECURITYHOLDERS.

         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 entitle the legal representatives or heirs of such Person or any
Securityholder 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.

SECTION 1002.           AMENDMENT.

         (a) This Trust Agreement may be amended from time to time by the
Trustees and the Depositor, without the consent of any Securityholders, (i) as
provided in Section 811 with respect to acceptance of appointment by a successor
Trustee; (ii) to cure any ambiguity, correct or supplement any provision herein
which 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 that shall not be inconsistent with the other provisions of this Trust
Agreement; or (iii) to modify, eliminate or add to any provisions of this Trust
Agreement to such extent as shall be necessary to ensure that the Trust shall be
classified for United States federal income tax purposes as a grantor trust at
all times that any Trust Securities are outstanding or to ensure that the Trust
shall not be required to register as an "investment company" under the
Investment Company Act; provided, however, that in the case of clause (ii), such
action shall not adversely

                                      -51-
<PAGE>   57

affect in any material respect the interests of any Securityholder, and any
amendments of this Trust Agreement shall become effective when notice thereof is
given to the Securityholders.

         (b) Except as provided in Section 601(c) or Section 1002(c) hereof, any
provision of this Trust Agreement may be amended by the Trustees and the
Depositor (i) with the consent of Securityholders representing not less than a
majority (based upon Liquidation Amounts) of the Trust Securities then
Outstanding; and (ii) upon receipt by the Trustees of an Opinion of Counsel to
the effect that such amendment or the exercise of any power granted to the
Trustees in accordance with such amendment shall not affect the Trust's status
as a grantor trust for United States federal income tax purposes or the Trust's
exemption from status of 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 Securityholder (such
consent being obtained in accordance with Section 603 or 606 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or 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 Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 603 or 606 hereof), this
paragraph (c) of this Section 1002 may not be amended.

         (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement
which would cause the Trust to fail or cease to qualify for the exemption from
status of an "investment company" under the Investment Company Act or to fail or
cease to be classified as 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, this Trust Agreement may not be amended in
a manner which imposes any additional obligation on the Depositor.

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

         (g) Neither the Property Trustee nor the Delaware Trustee shall be
required to enter into any amendment to this Trust Agreement which 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 1003.           SEPARABILITY.

         In case any provision in this Trust Agreement or in the Trust
Securities Certificates shall be invalid, illegal or unenforceable, the
validity, legality and enforceability of the remaining provisions shall not in
any way be affected or impaired thereby.

SECTION 1004.           GOVERNING LAW.

THE LAWS OF THE STATE OF DELAWARE (WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES
THEREOF).

SECTION 1005.           PAYMENTS DUE ON NON-BUSINESS DAY.

         If the date fixed for any payment on any Trust Security shall be a day
that is not a Business Day, then such payment need not be made on such date but
may be made on the next succeeding day which is a Business Day, except that, if
such Business Day is in the next succeeding calendar year, such payment shall be
made on the immediately preceding Business Day (and without any reduction of
interest or any other payment in respect of any such acceleration), in each case
with the same force and effect as though made on the date fixed for such
payment, and no distribution shall accumulate thereon for the period after such

including any successor by operation of law. Except in connection with a
consolidation, merger or sale involving the Depositor that is permitted under
Article XII of the Indenture and pursuant to which the assignee agrees in
writing to perform the Depositor's obligations hereunder, the Depositor shall
not assign its obligations hereunder.

SECTION 1007.           HEADINGS.

such notice, filed their names and addresses with the Property Trustee for that
purpose. Such notice, demand or other communication to or upon a Securityholder
shall be deemed to have been sufficiently given or made, for all purposes, upon

Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code of 1978, as amended) (collectively, "Bankruptcy Laws") or
otherwise join in the commencement of any proceeding against the Trust under any
Bankruptcy Law. In the event the Depositor or any of the Trustees takes action
in violation of this Section 1009, the Property Trustee agrees, for the benefit
of Securityholders, that at the expense of the Depositor (which expense shall be
paid prior to the filing), it shall file an answer with the bankruptcy court or
otherwise properly contest the filing of such petition by the Depositor or such
Trustee against the Trust or the commencement of such action and raise the
defense that the Depositor or such Trustee has agreed in writing not to take
such action and should be estopped and precluded therefrom. The provisions of

SECTION 1010.           TRUST INDENTURE ACT; CONFLICT WITH TRUST INDENTURE
                        ACT.

         (a) This Trust Agreement is subject to the provisions of the Trust
Indenture Act that are required to be part of this Trust Agreement and shall, to
the extent applicable, be governed by such provisions. Such provisions of the
Trust Indenture Act are deemed a part of this Trust Agreement and are
incorporated herein by this reference.

                                      -54-
<PAGE>   60

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

         (c) Lists of Holders of Trust Preferred Securities. (i) Each of the
Depositor and the Administrative Trustees on behalf of the Trust shall provide
the Property Trustee with such information as is required under Section 312(a)
of the Trust Indenture Act at the times and in the manner provided in Section
312(a) and (ii) the Property Trustee shall comply with its obligations under the
Trust Indenture Act.

         (d) Periodic Reports to Property Trustee. Each of the Depositor and the
Administrative Trustees on behalf of the Trust shall provide to the Property
Trustee, the Commission and the Holders of the Trust Securities, as applicable,

Trust).

         (e) Disclosure Information. The disclosure of information as to the
names and addresses of the Holders of Trust Securities in accordance with
Section 312 of the Trust Indenture Act, regardless of the source from which such
information was derived, shall not be deemed to be a violation of any existing
law or any law hereafter enacted which does not specifically refer to Section
312 of the Trust Indenture Act, nor shall the Property Trustee be held
accountable by reason of mailing any material pursuant to a request made under
Section 312(b) of the Trust Indenture Act.

         (f) If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Trust Agreement by any
of the provisions of the Trust Indenture Act, such required provision shall
control. If any provision of this Trust Agreement modifies or excludes any
provision of the Trust Indenture Act which may be so modified or excluded, the
latter provision shall be deemed to apply to this Trust Agreement as so modified
or to be excluded, as the case may be. The application of the Trust Indenture
Act to this Trust Agreement shall not affect the nature of the Securities as
equity securities representing undivided beneficial interests in the assets of
the Trust.

                        GUARANTEE AND INDENTURE.

         THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST THEREIN
BY OR ON BEHALF OF A SECURITYHOLDER OR ANY BENEFICIAL OWNER, WITHOUT ANY

AGREEMENT TO THE SUBORDINATION PROVISIONS AND OTHER TERMS OF THE GUARANTEE AND
THE INDENTURE, AND SHALL
