operation of the Trust created hereby and the issuance of the Trust Preferred
Securities and Common Securities referred to therein. Prior to the execution and

have any duties or obligations hereunder or with respect of the trust estate,
except as otherwise required by applicable law or as may be necessary to obtain
prior to such execution and delivery any licenses, consents or approvals
required by applicable law or otherwise. Notwithstanding the foregoing, the

transactions contemplated herein.

     4.   This Trust Agreement may be executed in one or more counterparts.

     5.   The number of Trustees of the Trust initially shall be four and
thereafter the number of trustees of the Trust shall be such number as shall be
fixed from time to time by a written instrument signed by the Depositor which
may increase or decrease the number of Trustees of the Trust; provided, however,
that to the extent required by the Business Trust Act, one trustee of the Trust
shall either be a natural person who is a resident of the State of Delaware or,
if not a natural person, an entity which has its principal place of business in
the State of Delaware. Subject to the foregoing, the Depositor is entitled to
appoint or remove without cause

     the Trust so that the Trust shall not be deemed to be an "investment

     Section 401.  Distributions.
                   -------------

          (a)  Distributions on the Trust Securities shall be cumulative, and
     shall accumulate whether or not there are funds of the Trust available for
     the payment of Distributions. Distributions shall accumulate from
     _____________, 2000, and, except during any Extended Interest Payment
     Period with respect to the Debentures, shall be payable quarterly in
     arrears on the last calendar day of March, June, September and December of
     each year, commencing on _____________, 2000.  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) 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 (each date on which
     distributions are payable in accordance with this Section 401(a), a
     "Distribution Date").

          (b)  The Trust Securities represent undivided beneficial interests in
     the Trust Property, and, as a practical matter, the Distributions on the
     Trust Securities shall be payable at a floating rate ("Floating Interest
     Rate") of 3.75% per annum over the three month London interbank offered
     rate ("Three-Month LIBOR Rate") from time to time in effect of the
     Liquidation Amount of the Trust Securities.  The Floating Interest Rate for
     each interest period will be set on the 15th day of the months March, June,
     September and December of each year; provided, that the initial Floating
     Interest Rate will be set on ____________, 2000 (each such date, an
     "Interest Reset Date").  If the Interest Reset Date is not a London
     Business Day, then such Interest Reset Date shall be the next succeeding
     day which is a London Business Day.

          (c)  The amount of Distributions payable for any full 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 number of days elapsed in a 360-day year of twelve 30-day
     months.  During any Extended Interest Payment Period with respect to the

                                      -17-
<PAGE>

     Debentures, Distributions on the Trust Preferred Securities shall be
     deferred for a period equal to the Extended Interest Payment Period. The
     amount of Distributions payable for any period shall include the Additional
     Amounts, if any.

          (d)  The "Three-Month LIBOR Rate" shall mean the rate determined in
     accordance with the following provisions:

               (i)  On the second London business day preceding each Interest
          Reset Date (each such date, an "Interest Determination Date"), First
          Union Trust Company, National Association (the "Calculation Agent"),
          will determine the Three-Month LIBOR Rate which shall be the rate for
          deposits in the London interbank market in U.S. dollars having a
          three-month maturity commencing on the second London business day
          immediately following such Interest Determination Date which appears
          on the Telerate Page 3750 as of 11:00 a.m., London time, on such
          Interest Determination Date. "Telerate Page 3750" means the display on
          Page 3750 of the Dow Jones Telerate Service (or such other page as may
          replace that page on that service for the purpose of displaying London
          interbank offered rates of major banks for U.S. dollar deposits). If
          the Three-Month LIBOR Rate on such Interest Determination Date does
          not appear on the Telerate Page 3750, such Three-Month LIBOR Rate will
          be determined as described in (ii) below.  London business day means
          any day on which dealings in deposits in U.S. dollars are transacted
          in the London interbank market.

               (ii) With respect to an Interest Determination Date for which the
          Three-Month LIBOR Rate does not appear on the Telerate Page 3750 as
          specified in (i) above, the Calculation Agent will request the
          principal London offices of each of four major banks in the London
          interbank market, as selected by the Calculation Agent, to provide the
          Calculation Agent with its offered quotation for deposits in U.S.
          dollars having a three-month maturity commencing on the second London
          business day immediately following such Interest Determination Date to
          prime banks in the London interbank market at approximately 11:00
          a.m., London time, on such Interest Determination Date and in a
          principal amount that is representative for a single transaction in
          such market at such time. If at least two such quotations are
          provided, the Three-Month LIBOR Rate on such Interest Determination
          Date will be the arithmetic mean (rounded upwards, if necessary, to
          the nearest one hundred-thousandth of a percentage point, with five or
          more one-millionths of one percentage point rounded upwards) of such
          quotations. If fewer than two quotations are provided, the Three-Month
          LIBOR Rate determined on such Interest Determination Date will be the
          arithmetic mean (rounded upwards, if necessary, to the nearest one
          hundred-thousandth of a percentage point, with five or more one-
          millionths of one percentage point rounded upwards) of the rates
          quoted at approximately 11:00 a.m., New York City time, on such
          Interest Determination

                                      -18-

          Date for loans in U.S. dollars to leading European banks, having a
          three-month maturity commencing on the second London business day
          immediately following such Interest Determination Date and in a
          principal amount that is representative for a single transaction in
          such market at such time by three major banks in New York City
          selected by the Calculation Agent; provided, however, if the banks so
          selected by the Calculation Agent are not quoting as aforesaid, the
          Three-Month LIBOR Rate with respect to such Interest Determination
          Date will be the Three-Month LIBOR Rate in effect on such Interest
          Determination Date.

          (e)  Distributions on the Trust Securities shall be made by the
     Property Trustee solely from the Payment Account and shall be payable on
     each Distribution Date only to the extent that the Trust has funds on hand
     and immediately available by 12:30 p.m. on each Distribution Date in the
     Payment Account for the payment of such Distributions.

          (f)  Distributions on the Trust Securities with respect to a
     Distribution Date shall be payable 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 Business Day immediately prior to the
     relevant Distribution Date.

     days prior to the Redemption Date to each Holder of Trust Securities to be
     redeemed, at such Holder's address appearing in the Securities Register.
     The Property Trustee shall have no responsibility for the accuracy of any
     CUSIP number contained in such notice. All notices of redemption shall
     state:

               (i)   the Redemption Date;

               (ii)  the Redemption Price;

               (iii) the CUSIP number;

               (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 shall
                     become due and payable upon each such Trust Security to be
                     redeemed and that Distributions thereon shall cease to
                     accumulate on and after said date, except as provided in
                     Section 402(d); and

                                      -19-
<PAGE>

               (vi)  the place or places at which Trust Securities are to be
                     surrendered for the payment of the Redemption Price; and

          (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 Trust has immediately available 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 402(c), the Property Trustee,
     subject to Section 402(c), shall, with respect to Trust Preferred
     Securities held in global form, deposit with the Clearing Agency for such
     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 Securities that are not held in global form, the Property
     Trustee, subject to Section 402(c), shall deposit with the Paying Agent
     funds sufficient to pay the applicable Redemption Price and shall give the
     Paying Agent irrevocable instructions and authority to pay the Redemption
     Price to the record holders thereof upon surrender of their Trust Preferred
     Securities Certificates. 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 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, (i) all rights of Securityholders holding Trust Securities so
     called for redemption shall cease, except the right of such Securityholders
     to receive the Redemption Price, (ii) such Securities shall cease to be
     Outstanding, (iii) the Clearing Agency for the Trust Preferred Securities
     or its nominee, as the registered Holder of the Global Trust Preferred
     Securities Certificate, shall receive a registered global certificate or
     certificates representing the Debentures to be delivered upon such
     distribution with respect to Trust Preferred Securities held by the
     Clearing Agency or its nominee, and (iv) any Trust Securities Certificates
     not 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 reissuance. 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 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

                                      -20-
<PAGE>

     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.

          (f)  Subject to Section 403(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 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.

     Section 403. Subordination of Common Securities.
                  ----------------------------------

          (a)  Payment of Distributions (including Additional Amounts, if
     applicable) on, and the Redemption Price of, the Trust Securities, as
     applicable, shall be made, subject to Section 402(f), pro rata among the
     Common 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 of the redemption, liquidation or other acquisition of Common
     Securities, shall be made unless payment in full in cash of all accumulated
     and unpaid Distributions (including Additional Amounts, if applicable) on
     all Outstanding Trust

                                      -21-
<PAGE>

     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 record 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 record holders of the
     Trust Preferred Securities and not the record holder of the Common
     Securities, and only the Holders of the Trust Preferred Securities shall
     have the right to direct the Property Trustee to act on their behalf.

     Section 404. Payment Procedures.
                  ------------------

     Payments of Distributions (including Additional Amounts, if applicable) 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, which will credit the relevant accounts on the applicable
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
Common Securityholder.

     Section 405. 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 and
information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrative Trustees shall (a) prepare and file
(or cause to be prepared and filed) the appropriate Internal Revenue Service
forms required to be filed in respect of the Trust in each taxable year of the
Trust; and (b) prepare and furnish (or cause to be prepared and furnished) to
each Securityholder the appropriate Internal Revenue Service forms required to
be furnished to such Securityholder or the information required to be provided
on such form. The Administrative Trustees shall provide the Depositor with a
copy of all such returns and reports promptly after such filing or furnishing.
The Property Trustee shall comply with United States federal withholding and
backup withholding tax laws and information reporting requirements with respect
to any payments to Securityholders under the Trust Securities.

                  -------------------------------------------

     Upon receipt under the Debentures of Additional Interest (as defined in
Section 1.1 of the Indenture), the Property Trustee, at the direction of an
Administrative Trustee or the Depositor, shall promptly pay any taxes, duties or
governmental charges of whatsoever nature (other than withholding taxes) imposed
on the Trust by the United States or any other taxing authority.

     Section 407. Payments Under Indenture.
                  ------------------------

     Any amount payable hereunder to any record holder of Trust Preferred
Securities shall be reduced by the amount of any corresponding payment such
Holder has directly received under the Indenture pursuant to Section 513(b) or
(c) hereof.

     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.

                  ---------------------------------

     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 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 Closing Date and on any date on which the underwriters
     exercise their over-allotment option, as applicable (an "Option Closing
     Date"), the Administrative Trustees shall cause Trust Securities
     Certificates, in an aggregate Liquidation Amount as provided in

                                      -23-

     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 or its Treasurer without further corporate action by the
     Depositor, in authorized denominations.

          (b)  A Trust 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
     Securities Certificate has been authenticated under this Trust Agreement.
     Each Trust 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 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 503. A 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 such custodian therefor, and such Global Trust
     Preferred Security shall constitute a single Trust Preferred Security for
     all purposes of this Trust Agreement.

          (b)  Notwithstanding any other provision in this Trust Agreement, no
     Global Trust Preferred Security may be exchanged for Trust Preferred
     Securities registered in the names of persons other than the Depositary or
     its nominee unless (i) the Depositary notifies the Debenture 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, (ii) the Depositor executes and delivers to the
     Trustee a written order stating that it elects to terminate the book-entry
     system through the Depositary or (iii) there shall have occurred and be
     continuing a Debenture Event of Default.

          (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 cancelled, 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

                                      -24-
<PAGE>

corresponding adjustment to its records. Upon any such surrender or adjustment
of a Global Trust Preferred Security by 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 Trust Preferred Securities issuable
in exchange for such Global Trust Preferred Security (or any portion thereof) in
accordance with the instructions of the Clearing Agency. The Property Trustee
shall not 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.

     (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 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)  The rights of owners of beneficial interests in a Global Trust
Preferred Security 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.

Section 504. Registration of Transfer and Exchange of Trust Preferred Securities
             --------------------------------------------------------
             Certificates.
             ------------

     (a)  The Depositor 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

                                      -25-
<PAGE>

exchanges of referred Securities Certificates as herein provided. The Property
Trustee shall be the initial Securities Registrar.

     (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, 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
record 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 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 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 Certificates, 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
Certificates.

     (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.

                   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,
the Administrative Trustees, or any one of them, on behalf of the Trust shall
execute and make available for delivery, 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 Trustees, the Paying Agent and the Securities Registrar shall treat the
Person in whose name any Trust Securities Certificate shall be registered in the
Securities Register as the owner of such Trust Securities Certificate 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
Trustee shall be as provided in the Trust Indenture Act. Each Holder, by
receiving and holding a Trust Securities Certificate, and each owner 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.

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, First Union Trust Company, National Association, as the
principal corporate trust office for such purposes. The Administrative Trustees
shall give prompt written notice to the Depositor and to 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 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 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

                                      -28-

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. 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.

     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, the Trustees
shall give all such notices and communications specified herein to be given to
the Clearing Agency, and shall have no 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 Trust Securities shall have no preemptive or similar rights.
     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%

                                      -29-
<PAGE>

     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.

     Section 601.  Limitations on Voting Rights
                   ----------------------------

          (a)  Except as provided in this Section 601, in Sections 512, 810 and
     1002 and in the Indenture and as otherwise required by law, no record
     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 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

                                      -30-
<PAGE>

     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 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 Trust Preferred Securityholders, stating the
time, place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 1008 to each Trust Preferred Securityholder of record, 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 Trust Preferred Securityholders
     are entitled to vote upon the written request of the Trust Preferred
     Securityholders of 25% of the Outstanding Trust Preferred Securities (based
     upon their aggregate Liquidation Amount) and the Administrative Trustees or
     the Property Trustee may, at any time in their discretion, call a meeting
     of Trust Preferred Securityholders to vote on any matters as to which the
     Trust Preferred Securityholders are entitled to vote.

                                      -31-
<PAGE>

          (b)  Trust Preferred Securityholders of record of 50% of the
     Outstanding Trust Preferred Securities (based upon their aggregate
     Liquidation Amount), present in person or by proxy, shall constitute a
     quorum at any meeting of Securityholders.

          (c)  If a quorum is present at a meeting, an affirmative vote by the
     Trust Preferred Securityholders of record present, in person or by proxy,
     holding more than a majority of the Trust Preferred Securities (based upon
     their aggregate Liquidation Amount) held by the Trust Preferred
     Securityholders 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 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 more 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 (based upon their aggregate Liquidation
Amount).

     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

                                      -32-
<PAGE>

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 or owners 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 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

                                      -33-
<PAGE>

     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 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 record holders of
the Trust Securities during normal business hours for any purpose reasonably
related to such record holder's interest as a record holder.

                                      -36-
<PAGE>

          (a)  the Trust Securities Certificates issued on the Closing Date on
     behalf of the Trust have been duly authorized and, shall have been, duly
     and validly executed, issued and delivered by the Administrative Trustees
     pursuant to the terms and provisions of, and in accordance with the
     requirements of, this Trust Agreement and the Securityholders shall 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
     the Trust (or the Trustees on behalf of the Trust) under the laws of the
     State of Delaware or any political subdivision thereof in connection with
     the execution, delivery and performance by the Bank, the Property Trustee
     or the Delaware Trustee, as the case may be, of this Trust Agreement.

                                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 the Trustees to expend or risk their own
     funds or otherwise incur any financial liability in the performance of any
     of their duties hereunder, or in the exercise of any of their rights or
     powers, if 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. 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 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, the Delaware
     Trustee or an Administrative Trustee has duties (including fiduciary
     duties) and liabilities relating thereto to the Trust or to the
     Securityholders, the Delaware Trustee or such Administrative Trustee shall
     not be liable to the Trust or to any Securityholder for such 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 Delaware Trustee or the Administrative Trustees
     otherwise existing at law or in equity, are agreed by the Depositor and the
     Securityholders to replace such other duties and liabilities of the
     Delaware Trustee or the Administrative Trustees, as the case may be.

          (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,

                                      -37-
<PAGE>

     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)    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;

                  (ii)   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;

                  (iii)  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;

                  (iv)   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; and

          (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 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 1008, notice
     of such Event of Default to the

                                      -38-
<PAGE>

     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;

          (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, then, except as to
     any matter as to which the Trust Preferred Securityholders are 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 if the Property Trustee does not
     receive such instructions of the Depositor within 10 Business Days after it
     has delivered such notice, or such reasonably shorter period of time set
     forth in such notice (which to the extent practicable shall not be less
     than 2 Business Days), it may, but shall be under no duty to, take or
     refrain from taking such action not inconsistent with this Trust Agreement
     as it shall deem advisable and in the best interests of the
     Securityholders, in which event the Property Trustee shall have no
     liability except for its own bad faith, negligence or willful misconduct;

          (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;

                                      -39-
<PAGE>

          (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, any filing under tax or securities
     laws 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 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, such counsel may be counsel to the Depositor or any of its
     Affiliates, and may include any of its employees; 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 reasonable security or indemnity against the costs, expenses and
     liabilities which might be incurred by it in compliance with such request
     or direction;

          (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, debenture, note or other evidence of
     indebtedness or other paper or document, unless requested in writing to do
     so by one or more Securityholders, but the Property Trustee may make such
     further inquiry or investigation into such facts or matters as it may see
     fit;

          (i)     the Property Trustee may execute any of the trusts or powers
     hereunder or perform any duties hereunder either directly or by or through
     its agents or attorneys, provided that the Property Trustee shall be
     responsible for its own negligence or recklessness with respect to
     selection of any agent or attorney appointed by it hereunder;

          (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,

                                      -40-
<PAGE>

     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 acting in accordance with such instructions; and

          (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.

                  ------------------------------------------------------

     The Recitals contained herein and in the Trust Securities Certificates

     The Depositor agrees:

          (a)     to pay to the Trustees from time to time compensation for all
     services rendered by them hereunder (which compensation shall not be

     of an express trust), in the case of the Property Trustee, as set forth in
     a written agreement between the Depositor and the Property Trustee;

          (b)     except as otherwise expressly provided herein, to reimburse
     the Trustees upon request for all reasonable expenses, disbursements and
     advances incurred or made by the Trustees in accordance with any provision
     of this Trust Agreement (including the reasonable compensation and the
     expenses and disbursements of its agents and counsel), except any such
     expense, disbursement or advance as may be attributable to such Trustee's
     negligence, bad faith or willful misconduct (or, in the case of the
     Administrative Trustees or the Delaware Trustee, any such expense,
     disbursement or advance as may be attributable to its, his or her gross

     attributable to its, his or her gross negligence, bad faith or willful
     misconduct).

any amount due and unpaid pursuant to this Section 806. The Property Trustee and
the Delaware Trustee may be the same Person.

                  ------------------------------------------------------------

          (a)     There shall at all times be a Property Trustee hereunder with

     a combined capital and surplus of at least $50,000,000. If any such Person
     publishes reports of condition at least annually, pursuant to law or to the
     requirements of its supervising or examining authority, then for the
     purposes of this Section 807, the combined capital and surplus of such
     Person shall be deemed to be its combined capital and surplus as set forth
     in its most recent report of condition so published. If at any time the
     Property Trustee with respect to the Trust Securities shall cease to be
     eligible in accordance with the provisions of this Section 807, it shall
     resign immediately in the manner and with the effect hereinafter specified
     in this Article VIII.

     years of age or a legal entity that shall act through one or more persons
     authorized to bind that entity.

          (c)     There shall at all times be a Delaware Trustee with respect to
     the Trust Securities. The Delaware Trustee shall either be (i) a natural
     person who is at least 21 years of age and a resident of the State of
     Delaware; or (ii) a legal entity with its principal place of business in

     Section 809. Co-Trustees and Separate Trustee.
                  --------------------------------

          (a)     Unless an Event of Default shall have occurred and be
     continuing, at any time or times, for the purpose of meeting the legal
     requirements of the Trust Indenture Act or of any jurisdiction in which any
     part of the Trust Property may at the time be located, the Depositor shall
     have power to appoint, and upon the written request of the Property
     Trustee, the Depositor shall for 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 co-trustee, jointly with the Property
     Trustee, of all or any part of such Trust Property, or to the extent
     required by law to act as separate trustee of any 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 join in
     such appointment within 15 days after the receipt by it of a request so to
     do, or in case a Debenture Event of Default has occurred and is continuing,
     the Property Trustee alone shall have power to make such appointment. Any
     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 in the United States that shall act through one or more
     persons authorized to bind such entity.

          (b)     Should any written instrument from the Depositor be required
     by any co-trustee or separate trustee so appointed for more fully
     confirming to such co-trustee or separate trustee such property, title,
     right, or power, any and all such instruments shall, on request, be
     executed, acknowledged, and delivered by the Depositor.

          (c)     Every co-trustee or separate trustee shall, to the extent
     permitted by law, but to such extent only, be appointed subject to the
     following terms, namely:

                  (i)  The Trust Securities shall be executed and delivered and
          all rights, powers, duties and obligations hereunder in respect of the
          custody of securities, cash and other personal property held by, or
          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.

                  (ii) The rights, powers, duties and obligations hereby
          conferred or imposed upon the Property Trustee in respect of any
          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.

                                      -43-
<PAGE>

                  (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 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.

          (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 Common
     Securityholder. 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 Common Securityholder, by Act of the Common
     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 Trust Preferred Securityholders, 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 Common Securityholder,
     by Act of the Common 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 shall have been so appointed
     by the Common Securityholder or the Trust Preferred Securityholders 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.

          (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 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).

<PAGE>

     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.

     unless at the time of such acceptance such successor Relevant Trustee shall
     be qualified and eligible under this Article VIII.

                  -----------------------------------------------------------

     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
corporation 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.

     Section 813. Preferential Collection of Claims Against Depositor or Trust.
                  ------------------------------------------------------------

     If and when the Property Trustee or the Delaware Trustee shall be or 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
Trustee, as the case may be, shall be subject to and shall take all actions
necessary in order to comply with the provisions of the Trust Indenture Act
regarding the collection of claims against the Depositor or Trust (or any such
other obligor).

          to the best of its knowledge it has continued to be eligible under
          said Section, a written statement to such effect; and

                  (ii) any change in the property and funds in its possession as
          Property Trustee since the date of its last report and any action
          taken by the Property Trustee in the performance of its duties
          hereunder which it has not previously reported and which in its
          opinion materially affects the Trust Securities.

          (b)     In addition the Property Trustee shall transmit to
     Securityholders such reports concerning the Property Trustee and its
     actions under this Trust Agreement as may be required pursuant to the Trust
     Indenture Act at the times and in the manner provided pursuant thereto.

          (c)     A copy of each such report shall, at the time of such

     upon which the Trust Securities are listed, and also with the Commission
     and the Depositor.

     Section 815. Reports to the Property Trustee.
                  -------------------------------

     The Depositor and the Administrative Trustees on behalf of the Trust shall

to any of the matters set forth in Section 314(c) of the Trust Indenture Act.
Any certificate or opinion required to be given by an officer pursuant to
Section 314(c)(1) of the Trust Indenture Act shall be given in the form of an
Officers' Certificate.

     Section 817. Number of Trustees.
                  ------------------

          (a)     The number of Trustees shall be five, provided that the Holder
     of all of the Common Securities by written instrument may increase or
     decrease the number of

                                      -47-
<PAGE>

     Administrative Trustees. The Property Trustee and the Delaware Trustee may
     be the same Person.

          (b)     If a Trustee ceases to hold office for any reason and the
     number of Administrative Trustees is not reduced pursuant to Section
     817(a), or if the number of Trustees is increased pursuant to Section
     817(a), a vacancy shall occur. The vacancy shall be filled with a Trustee
     appointed in accordance with Section 810.

          (c)     The death, resignation, retirement, removal, bankruptcy,
     incompetence or incapacity to perform the duties of a Trustee shall not
     operate to annul the Trust. Whenever a vacancy in the number of
     Administrative Trustees shall occur, until such vacancy is filled by the

     the Administrative Trustees in office, regardless of their number (and
     notwithstanding any other provision of this Agreement), shall have all the
     powers granted to the Administrative Trustees and shall discharge all the

     things and the execution of such instruments either in the name of the
     Trust or the names of the Administrative Trustees or otherwise as the

     is not prohibited by applicable law or contrary to the provisions of the
     Trust, as set forth herein.

<PAGE>

     Section 902.   Early Termination.
                    -----------------

     The first to occur of any of the following events is an "Early Termination
Event:"

          (a)  the occurrence of a Bankruptcy Event in respect of, or the
     dissolution or liquidation of, the Depositor;

          (b)  delivery of written direction to the Property Trustee by the
     Depositor at any time (which direction is wholly optional and within the
     discretion of the Depositor, subject to Depositor having received prior
     approval of the Board of Governors of the Federal Reserve System if so
     required under applicable guidelines, policies or regulations thereof) to
     dissolve the Trust and distribute the Debentures to Securityholders in
     exchange for the Trust Preferred Securities in accordance with Section 904;

          (c)  the redemption of all of the Trust Preferred Securities in
     connection with the redemption of all of the Debentures (whether upon a
     Debenture Redemption Date or the maturity of the Debenture); or

          (d)  an order for dissolution of the Trust shall have been entered by
     a court of competent jurisdiction.

     Section 903.   Termination.
                    -----------

     The respective obligations and responsibilities of the Trustees and the
Trust created and continued hereby shall terminate upon the latest to occur of
the following: (a) the distribution by the Property Trustee to Securityholders
upon the liquidation of the Trust pursuant to Section 904, or upon the
redemption of all of the Trust Securities pursuant to Section 402, of all
amounts required to be distributed hereunder upon the final payment of the Trust
Securities; (b) the payment of any expenses owed by the Trust; (c) the discharge
of all administrative duties of the Administrative Trustees, including the
performance of any tax reporting obligations with respect to the Trust or the
Securityholders; and (d) the filing of a Certificate of Cancellation by the
Administrative Trustee under the Business Trust Act.

     Section 904.   Liquidation.
                    -----------

          (a)  If an Early Termination Event specified in clause (a), (b), or
     (d) of Section 902 occurs or upon the Expiration Date, the Trust shall be
     liquidated by the Trustees as expeditiously as the Trustees determine to be
     possible by distributing, after satisfaction of liabilities to creditors of
     the Trust as provided by applicable law, to each Securityholder a Like
     Amount of Debentures, subject to Section 904(d). Notice of liquidation
     shall be given by the Property Trustee by first-class mail, postage
     prepaid, mailed not later 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 notices of liquidation
     shall:

               (i)    state the Liquidation Date;

                                      -49-
<PAGE>

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

               (iii)  provide such information with respect to the mechanics by
          which Holders may exchange Trust Securities Certificates for
          Debentures, or, if Section 904(d) applies, receive a Liquidation
          Distribution, as the Administrative Trustees or the Property Trustee
          shall deem appropriate.

          (b)  Except where Section 902(c) or 904(d) applies, in order to effect
     the liquidation of the Trust and distribution of the Debentures to
     Securityholders, the Property Trustee shall establish a record date for
     such distribution (which shall be not more than 45 days prior to the
     Liquidation Date) and, either itself acting as exchange agent or through
     the appointment of a separate exchange agent, shall 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 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 quoted on the OTC Bulletin Board 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 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,

                                      -50-
<PAGE>

     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.

     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 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 100% in Liquidation Amount 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,

                                      -51-
<PAGE>

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.

     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 or therein which may be inconsistent with any other
     provision herein or therein, 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 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 Trust 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

                                      -52-
<PAGE>

     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.
