                    incidental to the foregoing as the Property Trustee may from
                    time to time determine is necessary or advisable to give
                    effect to the terms of this Trust Agreement and protect and
                    conserve the Trust Property for the benefit of the

Securityholders.

     (c)  In connection with the issue and sale of the Preferred Securities, the

               advise the Trustees of actions they must take on behalf of the
               Trust, and prepare for execution and filing any documents to be
               executed and filed by the Trust or on behalf of the Trust, as the

               the applicable laws of any such States;

         (iii) the preparation for filing by the Trust and execution on behalf
               of the Trust of an application to The Nasdaq National Market(SM)

               upon notice of issuance of any Preferred Securities and to file
               or cause an Administrative Trustee to file thereafter with such

               out any of the foregoing activities.

     (d)  Notwithstanding anything herein to the contrary, the Trustees are
authorized and directed to conduct the affairs of the Trust and to operate the
Trust so that the Trust shall not be deemed to be an "investment company"
required to be registered under the Investment Company Act, shall be classified

                                       15
<PAGE>

United States federal income tax purposes and so that the Debentures shall be
treated as indebtedness of the Depositor for United States federal income tax
purposes.  In this connection, subject to Section 1002, the Depositor and the
Administrative Trustees are authorized to take any action, not inconsistent with
applicable law or this Trust Agreement, that each of the Depositor and the
Trustees determines in their discretion to be necessary or desirable for such

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

     (b)  The Property Trustee shall deposit in the Payment Account, promptly
upon receipt, all payments of principal of or interest on, and any other
payments or proceeds with respect to, the Debentures.  Amounts held in the
Payment Account shall not be invested by the Property Trustee pending
distribution thereof.


                                  ARTICLE IV
                           DISTRIBUTIONS; REDEMPTION

     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 _____________, 2001, and,
except during any Extended Interest Payment

                                       16
<PAGE>

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 March 31, 2001. If any date on which a Distribution is otherwise
payable on the Trust Securities is not a Business Day, then the payment of such
Distribution shall be made on the next succeeding day that is a Business Day
(and without any interest or other payment in respect of any such delay) 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. Distributions on the Trust Securities shall be payable at a rate
of ____% per annum of the Liquidation Amount of the Trust Securities.  The
amount of Distributions payable for any full 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 Debentures, Distributions on the Preferred
Securities shall be deferred for a period equal to the Extended Interest Payment
Period.

     (c)  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.

     (d)  Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities on the relevant record date, which shall be
the 15th day of March, June, September or December for Distributions payable on
the last calendar day of the respective month; provided, however, that for any
Trust Securities held in global form, Distributions shall be payable to the
Holder thereof as of one Business Day immediately preceding the Distribution
Date.

     Section 402.  Redemption.

     (a)  On each Debenture Redemption Date and on the maturity of the
Debentures, the Trust shall be required to redeem a Like Amount of Trust
Securities at the Redemption Price.

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

                                       17
<PAGE>

          (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

          (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
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 Preferred Securities held in global form, deposit
with the Clearing Agency for such 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 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 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 Securities
Register for the Trust Securities on the relevant record dates for the related
Distribution Dates.  If notice of redemption shall have been given and funds
deposited as required, then upon the date of such deposit, (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, but
without interest, (ii) such Trust Securities shall cease to be Outstanding,
(iii) the Clearing Agency for the Preferred Securities or its nominee, as the
registered Holder of the Global Preferred Securities Certificate, shall receive
a registered global certificate or certificates representing the Debentures to
be delivered upon such distribution with respect to Preferred Securities held by
the Clearing Agency or its nominee, and (iv) any Trust Securities Certificates
not held by the Clearing Agency for the 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

                                       18
<PAGE>

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 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 Preferred Securities.  The particular 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 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 such Liquidation Amount or an
integral multiple of such Liquidation Amount in excess thereof) of the
Liquidation Amount of Preferred Securities of a denomination larger than such
Liquidation Amount; provided, however, in the event the redemption relates only
to Preferred Securities purchased and held by the Depositor being redeemed in
exchange for a Like Amount of Debentures, the Property Trustee shall select
those particular Preferred Securities for redemption.  The Property Trustee
shall promptly notify the Securities Registrar in writing of the Preferred
Securities selected for redemption and, in the case of any 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 Preferred Securities shall relate,
in the case of any Preferred Securities redeemed or to be redeemed only in part,
to the portion of the Liquidation Amount of 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
Preferred Securities based on the Liquidation

                                       19
<PAGE>

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 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 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, Preferred Securities then due and payable.

     (b)  In the case of the occurrence of any Event of Default resulting from a
Debenture Event of Default, the Holder of Common Securities 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 Preferred Securities shall have been cured, waived or otherwise
eliminated.  Until any such Event of Default under this Trust Agreement with
respect to the Preferred Securities shall have been so cured, waived or
otherwise eliminated, the Property Trustee shall act solely on behalf of the
Holders of the Preferred Securities and not the Holder of the Common Securities,
and only the Holders of the 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 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 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

                                       20
<PAGE>

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.

     Section 406.  Payment Of Taxes, Duties, etc. of the Trust.

     Upon receipt under the Debentures of Additional Interest, 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 Holder of 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.

     Section 502.  The Trust Securities Certificates.

     The Preferred Securities Certificates shall be issued in minimum
denominations of the Liquidation Amount and integral multiples of the
Liquidation Amount in excess thereof, and the Common Securities Certificates
shall be issued in denominations of the Liquidation Amount and multiples thereof
(which may, in the case of the Common Securities, include fractional amounts).
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 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 Preferred Securities Certificate shall not be valid until
authenticated by the manual signature of an authorized signatory of the Property
Trustee in substantially the form of Exhibit E attached hereto.  The signature
shall be conclusive evidence that the Preferred Securities Certificate has been
authenticated under this Trust Agreement.  Each Preferred Security Certificate
shall be dated the date of its authentication.

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

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

     Section 503A. Global Preferred Security.

     (a)  Any Global 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 Preferred Security shall constitute a
single Preferred Security for all purposes of this Trust Agreement.

     (b)  Notwithstanding any other provision in this Trust Agreement, no Global
Preferred Security may be exchanged for 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 Preferred Securities and the Depositor
is unable to locate a qualified successor depositary, (ii) the Depositor
executes and delivers to the Debenture 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 Preferred Security is to be exchanged in whole or in part for a
beneficial interest in a Global Preferred Security, then either (i) such Global
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

                                       22
<PAGE>

cancelled, or equal to the Liquidation Amount of such other 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 Preferred Security (the "Applicable
Procedures"), shall instruct the Clearing Agency or its authorized
representative to make a corresponding adjustment to its records. Upon any such
surrender or adjustment of a Global 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 Preferred
Securities issuable in exchange for such Global 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 Preferred Security executed, authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global
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 Preferred Security, unless such Global Preferred Security is
registered in the name of a Person other than the Clearing Agency for such
Global Preferred Security or a nominee thereof.

     (e)  The Clearing Agency or its nominee, as the registered owner of a
Global Preferred Security, shall be considered the Holder of the Preferred
Securities represented by such Global Preferred Security for all purposes under
this Trust Agreement and the Preferred Securities, and owners of beneficial
interests in such Global 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 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
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 the
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 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 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 Preferred 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 Preferred Securities Certificates and Common

                                       23
<PAGE>

Securities Certificates (subject to Section 510 in the case of the Common
Securities Certificates) and registration of transfers and exchanges of
Preferred 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 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 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 Preferred Securities that have been
called for redemption.  At the option of a Holder, Preferred Securities
Certificates may be exchanged for other Preferred Securities Certificates in
authorized denominations of the same class and of a like aggregate Liquidation
Amount upon surrender of the Preferred Securities Certificates to be exchanged
at the office or agency maintained pursuant to Section 508.

     (c)  Every 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 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 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 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 Preferred Securities so selected for redemption, in whole or
in part, except the unredeemed portion of any such Preferred Securities being
redeemed in part.

     (d)  No service charge shall be made for any registration of transfer or
exchange of 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 Preferred Securities Certificates.

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

     Section 505.  Mutilated, Destroyed, Lost or Stolen Trust Securities
                   Certificates.

     If (a) any mutilated Trust Securities Certificate shall be surrendered to
the Securities Registrar, or if the Securities Registrar shall receive evidence
to its satisfaction of the destruction, loss or theft of any Trust Securities
Certificate; and (b) there shall be delivered to the Securities Registrar and
the Administrative Trustees such security or indemnity as may be required by
them to save each of them harmless, then in the absence of notice that such
Trust Securities Certificate shall have been acquired by a bona fide purchaser,
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 March
15, June 15, September 15 and December 15 of each year, 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.

     Section 508.  Maintenance of Office or Agency.

     The Administrative Trustees shall maintain, or cause to be maintained, in
The City of New York, or other location designated by the Administrative
Trustees, an office or offices or agency or agencies where 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, Wilmington Trust
Company, 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 must be 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 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, Preferred Securities Certificates shall
be issued in the form of one or more fully registered Global 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 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 Preferred Securities are
represented by a Global 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 obligation to provide notice to the owners of
the beneficial interest in the Global 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 Preferred Securities against payment of the purchase
price therefor, the Preferred Securities shall be fully paid and nonassessable
interests in the Trust.  The Holders of the 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.

                                       27
<PAGE>

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

                   ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

     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
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 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 Preferred Securities. The Trustees shall not revoke any action previously
authorized or approved by a vote of the Holders of the Outstanding Preferred
Securities, except by a subsequent vote of the Holders of the Outstanding
Preferred Securities. The Property Trustee shall notify each Holder of the
Outstanding Preferred Securities of any notice of default received from the
Debenture Trustee

                                       28
<PAGE>

with respect to the Debentures. In addition to obtaining the foregoing approvals
of the Holders of the 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
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 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 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 Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 1008 to each 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 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 Preferred Securityholders are entitled to
vote upon the written request of the Preferred Securityholders of 25% of the
Outstanding 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 Preferred Securityholders to vote on any
matters as to which the Preferred Securityholders are entitled to vote.

     (b)  Preferred Securityholders of record of 50% of the Outstanding
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
Preferred Securityholders of record present, in person or by proxy, holding more
than a majority of the Preferred Securities (based upon their aggregate
Liquidation Amount) held by the Preferred Securityholders of record present,
either in person or by proxy, at such meeting shall constitute the

                                       29
<PAGE>

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 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 respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, the Administrative Trustees or the Property Trustee may from time
to time fix a date, not more than 90 days prior to the date of any meeting of
Securityholders or the payment of Distribution or other action, as the case may
be, as a record date for the determination of the identity of the
Securityholders of record for such purposes.

     Section 608.  Acts of Securityholders.

     (a)  Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Trust Agreement to be given, made
or taken by Securityholders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Securityholders in
person or by an agent duly appointed in writing; and, except as otherwise
expressly provided herein, such action shall become effective when such
instrument or instruments are delivered to an Administrative Trustee.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders
signing such instrument or instruments.  Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Trust Agreement and (subject to Section 801) conclusive in favor
of the Trustees, if made in the manner provided in this Section 608.

     (b)  The fact and date of the execution by any Person of any such
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary 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 Preferred Securities shall be proved by the
Securities Register.

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

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

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

     Section 609.  Inspection of Records.

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

Delaware Trustee is a party or by which it is bound; or (iii) violate any law,
governmental rule or regulation of the United States or the State of Delaware,
as the case may be, governing the banking or trust powers of the Delaware Bank
or the Delaware Trustee (as appropriate in context) or any order, judgment or
decree applicable to the Delaware Bank or the Delaware Trustee;

     (e)  neither the authorization, execution or delivery by the Delaware
Trustee of this Trust Agreement nor the consummation of any of the transactions
by the Delaware Trustee contemplated herein or therein requires the consent or
approval of, the giving of notice to, the registration with or the taking of any
other action with respect to any governmental authority or agency under any
existing federal law governing the banking or trust powers of the Delaware Bank
or the Delaware Trustee, as the case may be, under the laws of the United States
or the State of Delaware; and

     (f)  there are no proceedings pending or, to the best of the Delaware
Trustee's knowledge, threatened against or affecting the Delaware Bank or the
Delaware Trustee in any court or before any governmental authority, agency or
arbitration board or tribunal which, individually or in the aggregate, would
materially and adversely affect the Trust or would question the right, power and
authority of the Delaware Trustee to enter into or perform its obligations as
one of the Trustees under this Trust Agreement.

      Section 703.  Representations and Warranties of Depositor.

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

     (a)  the Trust Securities Certificates issued on the Closing Date or the
Option Closing Date, if applicable, 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

                                       34
<PAGE>

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, 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;

                                       35
<PAGE>

         (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 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) and of any election by
the Depositor to accelerate the Maturity Date of the Debentures, as defined in
the Indenture, 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;

                                       36
<PAGE>

     (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
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;

     (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 Officers' 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

                                       37
<PAGE>

incurred by it in compliance with such request or direction; nothing contained
herein shall, however, relieve the Property Trustee of the obligation, upon the
occurrence of any Event of Default (that has not been cured or waived) to
exercise such of the rights and powers vested in it by this Trust Agreement, and
to use the same degree of care and skill in their exercise as a prudent man
would exercise or use under the circumstances in the conduct of his own affairs;

     (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, and the Property Trustee shall not be liable for the default or
misconduct of such other 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, 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.

      Section 804.  Not Responsible for Recitals or Issuance of Securities.

     The Recitals contained herein and in the Trust Securities Certificates
shall be taken as the statements of the Trust, and the Trustees do not assume
any responsibility for their correctness. The Trustees shall not be accountable
for the use or application by the Depositor of the proceeds of the Debentures.

                                       38
<PAGE>

     Section 805.  May Hold Securities.

     Any Trustee or any other agent of any Trustee or the Trust, in its
individual or any other capacity, may become the owner or pledgee of Trust
Securities and, subject to Sections 808 and 813 and except as provided in the
definition of the term "Outstanding" in Article I, may otherwise deal with the
Trust with the same rights it would have if it were not a Trustee or such other
agent.

     Section 806.  Compensation; Indemnity; Fees.

     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 limited by any
provision of law in regard to the compensation of a trustee 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 negligence, bad faith or willful
misconduct); and

     (c)  to indemnify each of the Trustees or any predecessor Trustee for, and
to hold the Trustees harmless against, any loss, damage, claims, liability,
penalty or expense of any kind or nature whatsoever, arising out of or in
connection with the acceptance or administration of this Trust Agreement,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder, except any such expense, disbursement or advance as may be
attributable to such Trustee's negligence, bad faith or willful misconduct for
(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 negligence, bad faith or willful misconduct).

     No Trustee may claim any Lien or charge on Trust Property as a result of
any amount due and unpaid pursuant to this Section 806.

     Section 807.  Corporate Property Trustee Required; Eligibility of Trustees.

     (a)  There shall at all times be a Property Trustee hereunder with respect
to the Trust Securities. The Property Trustee shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such and has 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

                                       39
<PAGE>

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

     (b)  There shall at all times be one or more Administrative Trustees
hereunder with respect to the Trust Securities.  Each Administrative Trustee
shall be either a natural person who is at least 21 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 the State of Delaware and
that otherwise meets the requirements of applicable Delaware law that shall act
through one or more persons authorized to bind such entity.

     Section 808.  Conflicting Interests.

     If the Property Trustee has or shall acquire a conflicting interest within
the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent and in the manner provided by,
and subject to the provisions of, the Trust Indenture Act and this Trust
Agreement.

     Section 809.  Co-Trustees and Separate Trustee.

     (a)  Unless a Debenture 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.

                                       40
<PAGE>

     (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.

          (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.

                                       41
<PAGE>

          (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 for 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 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 Preferred Securityholders, by Act of the
Securityholders of a majority in Liquidation Amount of the 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 Preferred Securityholders and
accepted appointment in the

                                       42
<PAGE>

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

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

     (a)  In case of the appointment hereunder of a successor Relevant Trustee
with respect to the Trust Securities and the Trust, the retiring Relevant

Trustee 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

     (b)  Upon request of any such successor Relevant Trustee, the Trust shall

confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the immediately preceding paragraph, as the case may be.

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

     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

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).

required pursuant to the Trust Indenture Act in the manner provided pursuant
thereto.

     (b)  A copy of each such report shall, at the time of such transmission to

     (c)  The death, resignation, retirement, removal, bankruptcy, incompetence

                      TERMINATION, LIQUIDATION AND MERGER

     Section 901.  Termination Upon Expiration Date.

     Unless earlier dissolved, the Trust shall automatically dissolve on,
__________, 2032 (the "Expiration Date") subject to distribution of the Trust
Property in accordance with Section 904.

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 Preferred
Securities in accordance with Section 904;

the redemption of all of the Debentures (whether upon a Debenture Redemption

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

     Section 903.  Termination.

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

<PAGE>

     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;

          (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 listed on the Nasdaq National
Market or on such other securities exchange or other organization as the
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.

                                       47
<PAGE>

     (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, 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 Preferred Securities, except that, if a Debenture Event of Default
has occurred and is continuing, the 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 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 Preferred Securities; or (b) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities) so long as the Successor Securities rank
the same as the 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 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 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 Preferred Securities (including any
Successor Securities) in any material respect; and (b) following such merger,

                                       48
<PAGE>

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, the Debentures, this Trust Agreement and
the Expense Agreement. For purposes of this Section 905, any such consolidation,
merger, sale, conveyance, transfer or other disposition as a result of which (a)
the Company is not the surviving Person, and (b) the same Person is not both (i)
the primary obligor in respect of the Debentures and (ii) the Guarantor under
that certain Preferred Securities Guarantee Agreement of even date herewith (the
"Guarantee") between the Company and Wilmington Trust Company, shall be deemed
to constitute a replacement of the Trust by a successor entity; provided further
that, notwithstanding the foregoing, in the event that upon the consummation of
such a consolidation, merger, sale, conveyance, transfer or other disposition,
the parent company (if any) of the Company, or its successor, is a bank holding
company or financial holding company or comparably regulated financial
institution, such parent company shall guarantee the obligations of the Trust
(and any successor thereto) under the Preferred Securities (including any
Successor Securities) at least to the extent provided by the Guarantee, the
Debentures, the Trust Agreement and the Expense Agreement. Notwithstanding the
foregoing, the Trust shall not, except with the consent of holders of 100% in
Liquidation Amount of the Preferred Securities, consolidate, amalgamate, merge
with or into, or be replaced by or convey, transfer or lease its properties and
assets substantially as an entirety to any other Person or permit any other
Person to consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger or replacement would cause the Trust or the
successor entity to be classified as other than a grantor trust for United
States federal income tax purposes.

                           MISCELLANEOUS PROVISIONS

     Section 1001.  Limitation of Rights of Securityholders.

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

     Section 1002.  Amendment.

     (a)  This Trust Agreement may be amended from time to time by the Trustees
and the Depositor, without the consent of any Securityholders, (i) as provided
in Section 811 with respect to acceptance of appointment by a successor Trustee;
(ii) to cure any ambiguity, correct or supplement any provision herein or
therein which may be inconsistent with any other provision herein or therein, or

of this Trust

                                       49
<PAGE>

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; or (iv) to reduce or increase the Liquidation Amount per
Trust Security and simultaneously to correspondingly increase or decrease the
number of Trust Securities issued and Outstanding solely for the purpose of
maintaining the eligibility of the Preferred Securities for quotation or listing
on any national securities exchange or other organization on which the Preferred
Securities are then quoted or listed (including, if applicable, the Nasdaq
National Market); 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 provided further, that in the case of clause (iv) the
aggregate Liquidation Amount of the Trust Securities Outstanding upon completion
of any such reduction must be the same as the aggregate Liquidation Amount of
the Trust Securities Outstanding immediately prior to such reduction or
increase; and any amendments of this Trust Agreement shall become effective when
notice thereof is given to the Securityholders (or in the case of an amendment
pursuant to clause (iv), as of the date specified in the notice).

     (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 in accordance with Section 603 or 606 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date; or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 603 or 606 hereof), this
paragraph (c) of this Section 1002 may not be amended.

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

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

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

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

and enforceability of the remaining provisions shall not in any way be affected
or impaired thereby.

THEREOF).

     Section 1005.  Payments Due on Non-Business Day.

     If the date fixed for any payment on any Trust Security shall be a day that
is not a Business Day, then such payment need not be made on such date but may

reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code of 1978, as amended) (collectively, "Bankruptcy Laws") or
otherwise join in the commencement of any proceeding against the Trust under any
Bankruptcy Law. In the event the Depositor or any of the Trustees takes action
in violation of this Section 1009, the Property Trustee agrees, for the benefit
of Securityholders, that at the expense of the Depositor (which expense shall be
paid prior to the filing), it shall file an answer with the bankruptcy court or
otherwise properly contest the filing of such petition by the Depositor or such
Trustee against the Trust or the commencement of such action and raise the
defense that the Depositor or such Trustee has agreed

Indenture Act that are required to be part of this Trust Agreement and shall, to
the extent applicable, be governed by such provisions.

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

     (c)  If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Trust Agreement by any
of the provisions of the Trust Indenture Act, such required provision shall
control. If any provision of this Trust Agreement modifies or excludes any
