     actual number of days elapsed in a partial month in that period. The amount
     of Distributions payable for any period shall include the Additional
     Amounts, if any.

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

     (b)  Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities at the close of business on the relevant
record date for such Distribution Date, which shall be the 15/th/ calendar day,
whether or not a Business Day, before the relevant Distribution Date.
Distributions payable on any Trust Securities that are not punctually paid on

Trust Securities are registered on the relevant record date, and such defaulted
Distribution will instead be payable to the Person in whose name such Trust
Securities are registered on the special record date or other specified date

accordance with the Indenture.

  SECTION 4.2.  REDEMPTION.

     (a)  On each Debenture Redemption Date and on the stated maturity of the
Debentures, the Issuer Trust will 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 Security Register.  All notices of
redemption shall state:

          (i)   the Redemption Date;

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

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

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

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

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

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

     (d)  If the Property Trustee gives a notice of redemption in respect of any
Capital Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 4.2(c), the Property Trustee will, with respect to
Book-Entry Capital Securities,

                                       17
<PAGE>

irrevocably deposit with the Clearing Agency for such Book-Entry Capital
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
Capital Securities. With respect to Capital Securities that are not Book-Entry
Capital Securities, the Property Trustee, subject to Section 4.2(c), will
irrevocably deposit with the Paying Agent, to the extent available therefor,
funds sufficient to pay the applicable Redemption Price and will give the Paying
Agent irrevocable instructions and authority to pay the Redemption Price to the
Holders of the Capital Securities upon surrender of their Capital 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, all rights of Holders
holding Trust Securities so called for redemption will cease, except the right
of such Holders to receive the Redemption Price and any Distribution payable in
respect of the Trust Securities on or prior to the Redemption Date, but without
interest, and such Trust Securities will cease to be outstanding. In the event
that any date on which any Redemption Price is payable is not a Business Day,
then payment of the Redemption Price payable on such date will be made on the
next succeeding day that is a Business Day (without any interest or other
payment in respect of any such delay), with the same force and effect as if made
on such date. In the event that payment of the Redemption Price in respect of
any Trust Securities called for redemption is improperly withheld or refused and
not paid either by the Issuer Trust or by the Depositor pursuant to the
Guarantee, Distributions on such Trust Securities will continue to accumulate,
as set forth in Section 4.1, from the Redemption Date originally established by
the Issuer Trust for such Trust Securities to the date such Redemption Price is
actually paid, in which case the actual payment date will be the date fixed for
redemption for purposes of calculating the Redemption Price.

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

  SECTION 4.3.  RANKING OF COMMON SECURITIES.

     (a) Payment of Distributions (including any Additional Amounts) on, the
Redemption Price of, and the Liquidation Distribution in respect of, the Trust
Securities, as applicable, shall be made, subject to Section 4.2(e), pro rata
among the Common Securities and the Capital Securities based on the Liquidation
Amount of the Trust Securities; provided, however, that if on any Distribution
Date, Redemption Date or Liquidation Date any Event of Default resulting from a
Debenture Event of Default specified in Section 501(1) or 501(2) of the
Indenture shall have occurred and be continuing, no payment of any Distribution
(including any Additional Amounts) on, Redemption Price of, or Liquidation
Distribution in respect 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 any Additional Amounts) on all Outstanding Capital
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 Capital Securities then called for redemption, or in
the case of payment of the Liquidation Distribution the full amount of such
Liquidation Distribution on all Outstanding Capital Securities, 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 any Additional Amounts) on, or the Redemption Price of,
the Capital Securities then due and payable.

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

  SECTION 4.4.  PAYMENT PROCEDURES.

     Payments of Distributions (including any Additional Amounts) in respect of
the Capital Securities shall, subject to the next succeeding sentence, 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 Capital Securities are held
by a Clearing Agency, such Distributions shall be made to the Clearing Agency in
immediately available funds.  A Holder of $1,000,000 or more in aggregate
Liquidation Amount of Capital Securities may receive payments of Distributions
(including any Additional Amounts) by wire transfer of immediately available
funds upon written request to the Property Trustee not later than the 15/th/
calendar day, whether or not a Business Day, before the relevant Distribution
Date.  Payments in respect of the Common Securities shall be made in such manner
as shall be mutually agreed between the Property Trustee and the Holders of the
Common Securities.

     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

Issuer Trust.  In this regard, the Administrative Trustees shall (a) prepare and

required to be filed in respect of the Issuer Trust in each taxable year of the
Issuer Trust, and (b) prepare and furnish (or cause to be prepared and
furnished) to each Holder all Internal Revenue Service forms required to be

information reporting requirements with respect to any payments to Holders under
the Trust Securities.

  SECTION 4.6.  PAYMENT OF EXPENSES OF THE ISSUER TRUST.

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

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

     Any amount payable hereunder to any Holder of Capital Securities (or any
Owner with respect thereto) shall be reduced by the amount of any corresponding
payment such Holder (or Owner) has directly received pursuant to Section 508 of
the Indenture or Section 5.14 of this Trust Agreement.

                                   ARTICLE 5

     The Capital Securities Certificates shall be issued in minimum

Certificates bearing the manual signatures of individuals who were, at the time
when such signatures shall have been affixed, authorized to sign on behalf of
the Issuer Trust or the Property Trustee or, if executed on behalf of the Issuer
Trust or the Property Trustee by facsimile, countersigned by the Securities
Registrar or its agent, shall be validly issued and entitled to the benefits of
this Trust Agreement, notwithstanding that such individuals or any of them shall
have ceased to be so authorized prior to the delivery of such Trust Securities
Certificates or did not hold such offices at the date of delivery of such Trust
Securities Certificates. A transferee of a Trust Securities Certificate shall
become a Holder, and shall be entitled to the rights and subject to the
obligations of a Holder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 5.4, 5.11
and 5.13.

  SECTION 5.4  REGISTRATION OF TRANSFER AND EXCHANGE OF CAPITAL SECURITIES
CERTIFICATES.

     The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 5.8, a register or registers for the purpose of
registering Trust Securities Certificates and transfers and exchanges of Capital
Securities Certificates (the "SECURITIES REGISTER") in which the transfer agent
and registrar designated by the Depositor (the "SECURITIES REGISTRAR"), subject
to such reasonable regulations as it may prescribe, shall provide for the
registration of Capital Securities Certificates and Common Securities
Certificates (subject to Section 5.10 in the case of the Common Securities
Certificates) and registration of transfers and exchanges of Capital Securities
Certificates as herein provided.  Wells Fargo Bank Minnesota shall be the
initial Securities Registrar.  The provisions of Sections 8.1, 8.3 and 8.6
herein shall apply to Wells Fargo Bank Minnesota also in its role as Securities
Registrar, for so long as Wells Fargo Bank Minnesota shall act as Securities
Registrar.

     Upon surrender for registration of transfer of any Capital Securities
Certificate at the office or agency maintained pursuant to Section 5.8, the
Administrative Trustees or any one of them shall execute on behalf of the Issuer
Trust (and if executed on behalf of the Issuer Trust by a facsimile signature,
such certificate shall be countersigned by the Securities Registrar or its
agent) and deliver, in the name of the designated transferee or transferees, one
or more new Capital 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 Capital Securities that have been

                                       21
<PAGE>

days before the day of selection for such redemption.

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

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

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

  SECTION 5.5.  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 Issuer 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 5.5, the Administrative Trustees or the Securities Registrar may require
the payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in connection therewith.  Any duplicate Trust Securities
Certificate issued pursuant to this Section shall constitute conclusive evidence
of an undivided beneficial interest in the assets of the Issuer Trust
corresponding to that evidenced by the lost, stolen or destroyed Trust
Securities Certificate, as if originally issued, whether or not the lost, stolen
or destroyed Trust Securities Certificate shall be found at any time.

  SECTION 5.6.  PERSONS DEEMED HOLDERS.

     The Issuer Trustees and the Securities Registrar shall each treat the
Person in whose name any Trust Securities Certificate shall be registered in the
Securities Register as the owner of such Trust Securities Certificate for the
purpose of receiving Distributions and for all other purposes whatsoever, and
none of the Issuer Trustees, the Administrative Trustees and the Securities
Registrar shall be bound by any notice to the contrary.

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

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

  SECTION 5.8.  MAINTENANCE OF OFFICE AGENCY.

     The Administrative Trustees shall designate an office or offices or agency
or agencies where Capital Securities Certificates may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Issuer Trustees in respect of the Trust Securities Certificates may be
served.  The Administrative Trustees initially designate Wells Fargo Bank
Minnesota, N.A., Wells Fargo Center, Sixth and Marquette, Minneapolis, Minnesota
55479-1019, Attention: Corporate Trust Services, as its office and agency for
such purposes.  The Administrative Trustee shall give prompt written notice to
the Depositor, the Property Trustees and to the Holders of any change in the
location of the Securities Register or any such office or agency.

  SECTION 5.9.  APPOINTMENT OF PAYING AGENT.

     The Paying Agent shall make Distributions to Holders from the Payment
Account and shall report the amounts of such Distributions to the Property
Trustee and the Administrative Trustees.  Any Paying Agent shall have the
revocable power to withdraw funds from the Payment Account solely for the
purpose of making the Distributions referred to above.  The Property Trustee may
revoke such power and remove the Paying Agent in its sole discretion.  The
Paying Agent shall initially be Wells Fargo Bank Minnesota.  Any Person acting
as Paying Agent shall be permitted to resign as Paying Agent upon 30 days'
written notice to the Administrative Trustees and the Property Trustee.  If
Wells Fargo Bank Minnesota shall no longer be the Paying Agent or a successor
Paying Agent shall resign or its authority to act be revoked, the Property
Trustee shall appoint a successor (which shall be a bank or trust company) that
is reasonably acceptable to the Administrative Trustees and the Depositor to act
as Paying Agent.  Such successor Paying Agent or any additional Paying Agent
shall execute and deliver to the Issuer Trustees an instrument in which such
successor Paying Agent or additional Paying Agent shall agree with the Issuer
Trustees that as Paying Agent, such successor Paying Agent or additional Paying
Agent will hold all sums, if any, held by it for payment to the Holders in trust
for the benefit of the Holders entitled thereto until such sums shall be paid to
such Holders.  The Paying Agent shall return all unclaimed funds to the Property
Trustee and upon removal of a Paying Agent such Paying Agent shall also return
all funds in its possession to the Property Trustee.  The provisions of Sections
8.1, 8.3 and 8.6 herein shall apply to Wells Fargo Bank Minnesota also in its
role as Paying Agent, for so long as Wells Fargo Bank Minnesota shall act as
Paying Agent and, to the extent applicable, to any other paying agent appointed
hereunder.  Any reference in this Agreement to the Paying Agent shall include
any co-paying agent unless the context requires otherwise.

  SECTION 5.10.  OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

     At the Time of Delivery, the Depositor shall acquire, and thereafter shall
retain, beneficial and record ownership of the Common Securities.  To the
fullest extent permitted by law, other than a transfer in connection with a
consolidation or merger of the Depositor into another Person, or any conveyance,
transfer or lease by the Depositor of its properties and assets substantially as
an entirety to any Person, pursuant to Section 801 of the Indenture, any
attempted transfer of the Common Securities shall be void.  The Administrative
Trustees shall cause each Common Securities Certificate issued to the Depositor
to contain a legend consistent with this Section 5.10.

  SECTION 5.11.  BOOK-ENTRY CAPITAL SECURITIES CERTIFICATES; COMMON SECURITIES

     (a) The Capital Securities Certificates, upon original issuance, will be
issued in the form of a typewritten Capital Securities Certificate or

behalf of, the Issuer Trust.  Such Capital Securities Certificate or
Certificates shall initially be registered on the Securities Register in the
name of Cede & Co., the nominee of the initial Clearing Agency, and no Owner
will receive a Definitive Capital Securities Certificate representing such
Owner's interest in such Capital Securities, except as provided in Section 5.13.
Unless and until Definitive Capital Securities Certificates have been issued to
Owners pursuant to Section 5.13;

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

          (ii)  the Securities Registrar and the Trustees shall be entitled to
     deal with the Clearing Agency for all purposes of this Trust Agreement
     relating to the Book-Entry Capital Securities Certificates (including the
     payment of the Liquidation Amount of and Distributions on the Capital
     Securities evidenced by Book-Entry Capital Securities Certificates and the
     giving of instructions or directions to Owners of Capital Securities
     evidenced by Book-Entry Capital Securities Certificates) as the sole Holder
     of Capital Securities evidenced by Book-Entry Capital Securities
     Certificates and shall have no obligations to the Owners thereof;

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

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

                                       24

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

  SECTION 5.12.  NOTICES TO CLEARING AGENCY.

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

  SECTION 5.13.  DEFINITIVE CAPITAL SECURITIES CERTIFICATES.

     If (a) the Depositor advises the Issuer Trustees in writing that the
Clearing Agency is no longer willing or able to properly discharge its
responsibilities with respect to the Capital Securities Certificates, and the
Depositor is unable to locate a qualified successor, (b) the Depositor at its
option advises the Issuer Trustees in writing that it elects to terminate the
book-entry system through the Clearing Agency or (c) after the occurrence of a
Debenture Event of Default, Owners of Capital Securities Certificates
representing beneficial interests aggregating at least a majority of the
Liquidation Amount advise the Administrative Trustees in writing that the
continuation of a book-entry system through the Clearing Agency is no longer in
the best interest of the Owners of Capital Securities Certificates, then the
Administrative Trustees shall notify the other Issuer Trustees and the Clearing
Agency, and the Clearing Agency, in accordance with its customary rules and
procedures, shall notify all Clearing Agency Participants for whom it holds
Capital Securities of the occurrence of any such event and of the availability
of the Definitive Capital Securities Certificates to Owners of such class or
classes, as applicable, requesting the same.  Upon surrender to the
Administrative Trustees of the typewritten Capital Securities Certificate or
Certificates representing the Book-Entry Capital Securities Certificates by the
Clearing Agency, accompanied by registration instructions, the Administrative
Trustees, or any one of them, shall execute the Definitive Capital Securities
Certificates in accordance with the instructions of the Clearing Agency, if
executed on behalf of the Issuer Trust by facsimile, countersigned by the
Securities Registrar or its agent.  Neither the Securities Registrar nor the
Trustees shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such instructions.
Upon the issuance of Definitive Capital Securities Certificates, the Issuer
Trustees shall recognize the Holders of the Definitive Capital Securities
Certificates as holders of Trust Securities.  The Definitive Capital Securities
Certificates shall be typewritten, printed, lithographed or engraved or may be
produced in any other manner as is reasonably acceptable to the Administrative
Trustees that meets the requirements of any stock exchange or automated
quotation system on which the Capital Securities are then listed or approved for
trading, as evidenced by the execution thereof by the Administrative Trustees or
any one of them.

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

     (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Holders shall not have any right or title therein other than the undivided
beneficial interest in the assets of the Issuer Trust

                                       25
<PAGE>

conferred by their Trust Securities and they shall have no right to call for any
partition or division of property, profits or rights of the Issuer Trust except
as described below. The Trust Securities shall be personal property giving only
the rights specifically set forth therein and in this Trust Agreement. The Trust
Securities shall have no preemptive or similar rights and when issued and
delivered to Holders against payment of the purchase price therefor will be
fully paid and nonassessable by the Issuer Trust. The Holders of the Trust
Securities, in their capacities as such, shall be entitled to the same
limitation of personal liability extended to stockholders of private
corporations for profit organized under the General Corporation Law of the State
of Delaware.

     (b)  For so long as any Capital 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
Property Trustee or the Holders of at least 25% in Liquidation Amount of the
Capital Securities then Outstanding shall have the right to make such
declaration by a notice in writing to the Depositor, the Debenture Trustee and
the Property Trustee, in the case of notice by the Holders of the Capital
Securities, or to the Depositor, the Debenture Trustee and the Holders of the
Capital Securities, in the case of notice by the Property Trustee.

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

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

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

               (B) any accrued Additional Interest (as defined in the Indenture)
          on all of the Debentures,

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

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

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

                                       26
<PAGE>

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

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

     (c) For so long as any Capital Securities remain Outstanding, to the
fullest extent permitted by law and subject to the terms of this Trust Agreement
and the Indenture, upon a Debenture Event of Default specified in Section 501(1)
or 501(2) of the Indenture, any Holder of Capital Securities shall have the
right to institute a proceeding directly against the Depositor, pursuant to
Section 508 of the Indenture, for enforcement of payment to such Holder of any
amounts payable in respect of Debentures having an aggregate principal amount
equal to the aggregate Liquidation Amount of the Capital Securities of such
Holder (a "DIRECT ACTION").  Except as set forth in Section 5.14(b) and this
Section 5.14(c), the Holders of Capital Securities shall have no right to
exercise directly any right or remedy available to the holders of, or in respect
of, the Debentures.

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

                                       27

  SECTION 5.15.  CUSIP NUMBERS.

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

                       ACTS OF HOLDERS; MEETINGS; VOTING

  SECTION 6.1.  LIMITATIONS ON VOTING RIGHTS.

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

     (b) So long as any Debentures are held by the Property Trustee on behalf of
the Issuer Trust, the Issuer Trustees shall not (i) direct the time, method and
place of conducting any proceeding for any remedy available to the Debenture
Trustee, or execute any trust or power conferred on the Debenture Trustee with
respect to the Debentures, (ii) waive any past default that may be waived under
Section 513 of the Indenture, (iii) exercise any right to rescind or annul a
declaration that the principal of all the Debentures shall be due and payable,
or (iv) consent to any amendment, modification or termination of the Indenture
or the Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of at least a Majority in
Liquidation Amount of the Capital Securities, provided, however, that where a
consent under the Indenture would require the consent of each holder of
Debentures affected thereby, no such consent shall be given by the Property
Trustee without the prior written consent of each Holder of Capital Securities.
The Property Trustee shall not revoke any action previously authorized or
approved by a vote of the Holders of the Capital Securities, except by a
subsequent vote of the Holders of the Capital Securities.  The Property Trustee
shall notify all Holders of the Capital Securities of any notice of default
received with respect to the Debentures.  In addition to obtaining the foregoing
approvals of the Holders of the Capital Securities, prior to taking any of the
foregoing actions, the Issuer Trustees shall, at the expense of the Depositor,
obtain an Opinion of Counsel experienced in such matters to the effect that such
action shall not cause the Issuer Trust to be taxable as a corporation or
classified as other than a grantor trust for United States Federal income tax
purposes.

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Issuer Trustees otherwise propose to effect, (i) any action that would adversely
affect in any material respect the powers, preferences or special rights of the
Capital Securities, whether by way of

                                       28
<PAGE>

amendment to the Trust Agreement or otherwise, or (ii) the dissolution and
winding-up of the Issuer Trust, other than pursuant to the terms of this Trust
Agreement, then the Holders of Outstanding Capital Securities as a class will be
entitled to vote on such amendment or proposal and such amendment or proposal
shall not be effective except with the approval of the Holders of at least a
Majority in Liquidation Amount of the Capital Securities. Notwithstanding any
other provision of this Trust Agreement, no amendment to this Trust Agreement
may be made if, as a result of such amendment, it would cause the Issuer Trust
to be taxable as a corporation or classified as other than a grantor trust for
United States Federal income tax purposes.

  SECTION 6.2.  NOTICE OF MEETINGS.

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

  SECTION 6.3.  MEETINGS OF HOLDERS OF THE CAPITAL SECURITIES.

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

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

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

  SECTION 6.4.  VOTING RIGHTS.

     Holders shall be entitled to one vote for each $25 of Liquidation Amount
represented by their Outstanding Trust Securities in respect of any matter as to
which such Holders are entitled to vote.

  SECTION 6.5.  PROXIES, ETC.

     At any meeting of Holders, any Holder entitled to vote thereat may vote by
proxy, provided that no proxy shall be voted at any meeting unless it shall have
been placed on file with the Property Trustee, or with such other officer or
agent of the Issuer Trust as the Property

                                       29
<PAGE>

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

  SECTION 6.6.  HOLDER ACTION BY WRITTEN CONSENT.

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

  SECTION 6.7.  RECORD DATE FOR VOTING AND OTHER PURPOSES.

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

  SECTION 6.8.  ACTS OF HOLDERS.

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

     The fact and date of the execution by any Person of any such instrument or
writing may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds, certifying that the individual signing such instrument
or writing acknowledged to him the execution thereof.  Where such

                                       30
<PAGE>

execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority. The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner that any Issuer Trustee receiving the same deems sufficient.

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

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

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

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

     A Holder 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 Issuer Trust, any Issuer Trustee, or any person or entity.

  SECTION 6.9.  INSPECTION OF RECORDS.

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

                         REPRESENTATIONS AND WARRANTIES

  SECTION 7.1.  REPRESENTATIONS AND WARRANTIES OF THE PROPERTY TRUSTEE AND THE
DELAWARE TRUSTEE.

     The Property Trustee and the Delaware Trustee, each severally on behalf of

respect to any governmental authority or agency under any existing law of the
United States or the State of Delaware governing the banking, trust or general

Issuer Trust or would question the right, power and authority of the Property
Trustee or the

                                       32
<PAGE>

Delaware Trustee, as the case may be, to enter into or perform its obligations
as one of the Trustees under this Trust Agreement.

  SECTION 7.2.  REPRESENTATIONS AND WARRANTIES OF DEPOSITOR.

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

     (a) the Trust Securities Certificates issued at the Time of Delivery on
behalf of the Issuer Trust have been duly authorized and will have been duly and
validly executed, issued and delivered by the Issuer Trustees pursuant to the

Agreement, and the Holders will be, as of such date, entitled to the benefits of
this Trust Agreement; and

     (b) there are no taxes, fees or other governmental charges payable by the
Issuer Trust (or the Issuer Trustees on behalf of the Issuer Trust) under the

with the execution, delivery and performance by any Issuer Trustee of this Trust
Agreement.

                                   ARTICLE 8
                              THE ISSUER TRUSTEES

  SECTION 8.1.  CERTAIN DUTIES AND RESPONSIBILITIES.

     (a) The duties and responsibilities of the Issuer Trustees shall be as
provided by this Trust Agreement, subject to Section 10.10 hereof.
Notwithstanding the foregoing, but subject to Section 8.1(c), no provision of
this Trust Agreement shall require any of the Issuer Trustees to expend or risk
its or their own funds or otherwise incur any financial liability in the
performance of any of its or their duties hereunder, or in the exercise of any
of its or their rights or powers, if it or they shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it.  Whether or not therein
expressly so provided, every provision of this Trust Agreement relating to the
conduct or affecting the liability of or affording protection to the Issuer
Trustees shall be subject to the provisions of this Section 8.1.  To the extent
that, at law or in equity, an Administrative Trustee has duties and liabilities
relating to the Issuer Trust or to the Holders, such Administrative Trustee
shall not be liable to the Issuer Trust or to any Holder for such Administrative
Trustee's good faith reliance on the provisions of this Trust Agreement.  The
provisions of this Trust Agreement, to the extent that they restrict the duties
and liabilities of the Administrative Trustees otherwise existing at law or in
equity, are agreed by the Depositor and the Holders to replace such other duties
and liabilities of the Administrative Trustees.

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

                                       33
<PAGE>

Trust Security. This Section 8.1(b) does not limit the liability of the Issuer
Trustees expressly set forth elsewhere in this Trust Agreement or, in the case
of the Property Trustee, in the Trust Indenture Act.

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

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

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

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

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

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

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

          (iii) the Property Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with
     the direction of the Holders of at least a Majority in Liquidation Amount
     of the Capital Securities relating to the time, method and place of
     conducting any proceeding for any remedy available to the Property

                                       34
<PAGE>

     Trustee, or exercising any trust or power conferred upon the Property
     Trustee under this Trust Agreement;

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

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

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

          (vii) subject to Section 8.1(c), no provision of this Trust Agreement
     shall require the Property Trustee to expend or risk its own funds or
     otherwise incur personal financial liability in the performance of any of
     its duties or in the exercise of any of its rights or powers, if the
     Property Trustee shall have reasonable grounds for believing that the
     repayment of such funds or liability is not reasonably assured to it under
     the terms of this Trust Agreement or adequate indemnity against such risk
     or liability is not reasonably assured to it.

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

  SECTION 8.2.  CERTAIN NOTICES.

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

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

     The Property Trustee shall not be deemed to have knowledge of any Event of
Default unless the Property Trustee shall have received written notice or a
Responsible Officer of the

                                       35

have obtained actual knowledge of such Event of Default.

  SECTION 8.3.  CERTAIN RIGHTS OF PROPERTY TRUSTEE.

     Subject to the provisions of Section 8.1:

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

     (b) if (i) in performing its duties under this Trust Agreement the Property
Trustee is required to decide between alternative courses of action, (ii) in
construing any of the provisions of this Trust Agreement the Property Trustee
finds the same ambiguous or inconsistent with any 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
Holders of the Capital Securities are entitled to vote under the terms of this
Trust Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting the Depositor's opinion as to the course of action to be taken;
provided, however, that if the Depositor fails to deliver such opinion, the
Property Trustee shall take such action, or refrain from taking such action, as
the Property Trustee shall deem advisable and in the best interests of the
Holders, 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 contemplated by this Trust
Agreement shall be sufficiently evidenced by an Officers' Certificate;

     (d) any direction or act of an Administrative Trustee contemplated by this
Trust Agreement shall be sufficiently evidenced by a certificate executed by

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

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

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

                                       36
<PAGE>

by it in compliance with such request or direction; provided that, nothing
contained in this Section 8.3(g) shall be taken to relieve the Property Trustee,
upon the occurrence of an Event of Default, of its obligation to exercise the
rights and powers vested in it by this Trust Agreement;

     (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,

unless requested in writing to do so by one or more Holders, but the Property

     (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 (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 any Issuer 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 such Person 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 any Issuer Trustee shall be construed to be a duty.

  SECTION 8.4.  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 Issuer Trust and the Depositor, and the
Issuer Trustees do not assume any responsibility for their correctness.  The
Issuer Trustees shall not be accountable for the use or application by the
Depositor of the proceeds of the Debentures.

  SECTION 8.5.  MAY HOLD SECURITIES.

     Any Issuer Trustee or any other agent of any Issuer Trustee or the Issuer
Trust, in its individual or any other capacity, may become the owner or pledgee
of Trust Securities and, subject to Sections 8.8 and 8.13, and except as
provided in the definition of the term

                                       37
<PAGE>

"Outstanding" in Article I, may otherwise deal with the Issuer Trust with the
same rights it would have if it were not Issuer Trustee or such other agent.

  SECTION 8.6.  COMPENSATION; INDEMNITY; FEES.

     The Depositor agrees:

     (a) to pay to the Issuer Trustees from time to time such reasonable
compensation for all services rendered by them hereunder as may be separately
agreed by the Depositor and the Issuer Trustees from time to time (which
compensation shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust);

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

     (c) to the fullest extent permitted by applicable law, to indemnify and
hold harmless (i) each Issuer Trustee, (ii) any Affiliate of any Issuer Trustee,
(iii) any officer, director, shareholder, employee, representative or agent of
any Issuer Trustee, and (iv) any employee or agent of the Issuer Trust (referred
to herein as an "INDEMNIFIED PERSON") from and against any loss, damage,
liability, tax, penalty, expense or claim of any kind or nature whatsoever
incurred by such Indemnified Person by reason of the creation, operation or
dissolution of the Issuer Trust or any act or omission performed or omitted by
such Indemnified Person in good faith on behalf of the Issuer Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by this Trust Agreement, except
that no Indemnified Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Indemnified Person by reason of
negligence, bad faith or willful misconduct with respect to such acts or
omissions.

     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement and the removal or resignation of any Issuer Trustee.

     No Issuer Trustee may claim any Lien on any Trust Property as a result of
any amount due pursuant to this Section 8.6.

     The Depositor and any Issuer Trustee may engage in or possess an interest
in other business ventures of any nature or description, independently or with
others, similar or dissimilar to the business of the Issuer Trust, and the
Issuer Trust and the Holders of Trust Securities shall have no rights by virtue
of this Trust Agreement in and to such independent ventures or the income or
profits derived therefrom, and the pursuit of any such venture, even if
competitive with the business of the Issuer Trust, shall not be deemed wrongful
or improper.  Neither the Depositor nor any Issuer Trustee shall be obligated to
present any particular investment or other opportunity to the Issuer Trust even
if such opportunity is of a character that, if presented to the Issuer Trust,
could be taken by the Issuer Trust, and the Depositor and any Issuer Trustee
shall have the right to take for its own account (individually or as a partner
or fiduciary) or to

                                       38
<PAGE>

recommend to others any such particular investment or other opportunity. Any
Issuer Trustee may engage or be interested in any financial or other transaction
with the Depositor or any Affiliate of the Depositor, or may act as depository
for, trustee or agent for, or act on any committee or body of holders of,
securities or other obligations of the Depositor or its Affiliates.

  SECTION 8.7.  CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF ISSUER
TRUSTEES AND ADMINISTRATIVE 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 a
national or state chartered bank and eligible pursuant to the Trust Indenture
Act to act as such and that 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 8.7 and to the extent permitted
by the Trust Indenture Act, the combined capital and surplus of such Person
shall be deemed to be its combined capital and surplus as set forth in its most
recent report of condition so published.  If at any time the Property Trustee
with respect to the Trust Securities shall cease to be eligible in accordance
with the provisions of this Section 8.7, it shall resign immediately in the
manner and with the effect hereinafter specified in this Article VIII.  At the
time of appointment, the Property Trustee must have securities rated in one of
the three highest rating categories by a nationally recognized statistical
rating organization.

     (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 and that shall
act through one or more persons authorized to bind such entity.

  SECTION 8.8.  CONFLICTING INTERESTS.

     (a) 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.

     (b) The Guarantee Agreement and the Indenture shall be deemed to be
specifically described in this Trust Agreement for the purposes of clause (i) of
the first proviso contained in Section 310(b) of the Trust Indenture Act.

  SECTION 8.9.  CO-TRUSTEES AND SEPARATE TRUSTEE.

     Unless and until 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

                                       39
<PAGE>

of any jurisdiction in which any part of the Trust Property may at the time be
located, the Holder of Common Securities and the Administrative Trustees shall
have the power to appoint one or more Persons 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. If a Debenture Event of Default shall have
occurred and be continuing, the Property Trustee shall have the sole power to so
appoint such a co-trustee or separate trustee, and upon the written request of
the Property Trustee, the Depositor and the Administrative Trustees 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,
such co-trustee or separate trustee. Any co-trustee or separate trustee
appointed pursuant to this Section 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.

     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.

     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:

     (a) The Trust Securities shall be executed by one or more Administrative
Trustees, and the Trust Securities shall be delivered by the Property Trustee,
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 Property Trustee specified hereunder shall be
exercised solely by the Property Trustee and not by such co-trustee or separate
trustee.

     (b) 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.

     (c) 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
8.9, and, in case a Debenture Event of Default has occurred and is continuing,
the Property Trustee shall have 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

                                       40
<PAGE>

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 resigning or removed may be
appointed in the manner provided in this Section 8.9.

     (d)  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.

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

     (f)  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 8.10.  RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     No resignation or removal of any Issuer Trustee (the "RELEVANT TRUSTEE")
and no appointment of a successor Issuer Trustee pursuant to this Article VIII
shall become effective until the acceptance of appointment by the successor
Issuer Trustee in accordance with the applicable requirements of Section 8.11.

     Subject to the immediately preceding paragraph, the Relevant Trustee may
resign at any time by giving written notice thereof to the Holders and by
appointing a successor Relevant Trustee.  The Relevant Trustee shall appoint a
successor by requesting from at least three Persons meeting the eligibility
requirements its expenses and charges to serve as the Relevant Trustee on a form
provided by the Administrative Trustees, and selecting the Person who agrees to
the lowest expenses and charges.  If the instrument of acceptance by the
successor Issuer Trustee required by Section 8.11 shall not have been delivered
to the Relevant Trustee within 60 days after the giving of such notice of
resignation, the Relevant Trustee may petition, at the expense of the Depositor,
in the case of the Property Trustee, any court of competent jurisdiction for the
appointment of a successor Relevant Trustee.

     The Administrative Trustees, or any of them, may be removed at any time by
Act of the Holders of Common Securities delivered to the Relevant Trustee.

     The Property Trustee or the Delaware Trustee, or both of them, may be
removed by Act of the Holders of at least a Majority in Liquidation Amount of
the Capital Securities, delivered to the Relevant Trustee (in its individual
capacity and, in the case of the Property Trustee, on behalf of the Issuer
Trust) (i) for cause (including upon the occurrence of an Event of Default
described in subparagraph (d) of the definition thereof with respect to the
Relevant Trustee), or (ii) at any time if a Debenture Event of Default shall
have occurred and be continuing.  Unless and until 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 any time by Act of the Holders of
the Common Securities.

     If a resigning Property Trustee or Delaware Trustee shall fail to appoint a
successor, or if the Property Trustee or the Delaware Trustee shall be removed
or become incapable of acting as Issuer Trustee, or if a vacancy shall occur in
the office of the Property Trustee or the Delaware Trustee for any cause, the
Holders of the Common Securities by Act of such Holders delivered to

                                       41
<PAGE>

the Relevant Trustee or, if a Debenture Event of Default shall have occurred and
be continuing, the Holders of the Capital Securities, by Act of the Holders of
not less than 25% in aggregate Liquidation Amount of the Capital Securities then
Outstanding delivered to such Relevant Trustee, may appoint a successor Relevant
Trustee or Trustees, and such successor Issuer Trustee shall comply with the
applicable requirements of Section 8.11. If no successor Relevant Trustee shall
have been so appointed by the Holders of the Common Securities or Capital
Securities, as the case may be, and accepted appointment in the manner required
by Section 8.11, any Holder, on behalf of such Holder and all others similarly
situated, or any other Issuer Trustee, may petition any court of competent
jurisdiction for the appointment of a successor Relevant Trustee.

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

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

  SECTION 8.11.  ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

     In case of the appointment hereunder of a successor Relevant Trustee, the
retiring Relevant Trustee and each successor Relevant Trustee with respect to
the Trust Securities shall execute and deliver an amendment hereto wherein each
successor Relevant Trustee shall accept such appointment and which (a) 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 Issuer Trust, and (b) shall add to or change any of the
provisions of this Trust Agreement as shall be necessary to provide for or
facilitate the administration of the Issuer Trust by more than one Relevant
Trustee, it being understood that nothing herein or in such amendment shall
constitute such Relevant Trustees co-trustees and upon the execution and
delivery of such amendment 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, other than the filing of an amendment to the Certificate of
Trust to the extent required under the Delaware Business Trust Act; but, on
request of the Issuer Trust or any successor Relevant Trustee such retiring
Relevant Trustee shall duly assign, transfer and deliver to such successor
Relevant Trustee all Trust Property, all proceeds thereof and money held by such
retiring Relevant Trustee hereunder with respect to the Trust Securities and the
Issuer Trust.

                                       42
<PAGE>

     Upon request of any such successor Relevant Trustee, the Issuer Trust shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the preceding paragraph.

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

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

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

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

     If and when the Property Trustee shall be or become a creditor of the
Depositor or the Issuer Trust (or any other obligor upon the Capital
Securities), the Property Trustee shall be subject to the provisions of the
Trust Indenture Act regarding the collection of claims against the Depositor or
the Issuer Trust (or any such other obligor).

  SECTION 8.14.  TRUSTEE MAY FILE PROOFS OF CLAIM.

     In case of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other similar judicial
proceeding relative to the Issuer Trust or any other obligor upon the Trust
Securities or the property of the Issuer Trust or of such other obligor or their
creditors, the Property Trustee (irrespective of whether any Distributions on
the Trust Securities shall then be due and payable and irrespective of whether
the Property Trustee shall have made any demand on the Issuer Trust for the
payment of any past due Distributions) shall be entitled and empowered, to the
fullest extent permitted by law, by intervention in such proceeding or
otherwise:

     (a)  to file and prove a claim for the whole amount of any Distributions
owing and unpaid in respect of the Trust Securities and to file such other
papers or documents as may be necessary or advisable in order to have the claims
of the Property Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Property Trustee, its agents and
counsel) and of the Holders allowed in such judicial proceeding, and

     (b)  to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same; and any custodian,
receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such
payments to the Property Trustee and, in the event the Property Trustee

                                       43
<PAGE>

shall consent to the making of such payments directly to the Holders, to pay to
the Property Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Property Trustee, its agents and
counsel, and any other amounts due the Property Trustee.

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

  SECTION 8.15.  REPORTS BY PROPERTY TRUSTEE.

     (a)  Within 60 days after May 15 of each year commencing with May 15, 2002,
the Property Trustee shall transmit to all Holders in accordance with Section
10.8, and to the Depositor, a brief report dated as of the immediately preceding
May 15 with respect to:

          (i)    its eligibility under Section 8.7 or, in lieu thereof, if to
     the best of its knowledge it has continued to be eligible under said
     Section, a written statement to such effect;

     its obligations under this Trust Agreement during the twelve-month period
     (or, in the case of the initial report, the period since the Closing Date)
     ending with such May 15 or, if the Property Trustee has not complied in any
     material respect with such obligations, a description of such
     noncompliance; and

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

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

     (c)  A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with the Depositor.

  SECTION 8.16.  REPORTS TO THE PROPERTY TRUSTEE.

     Each of the Depositor and the Administrative Trustees shall provide to the
Property Trustee such documents, reports and information as required by Section
314 of the Trust Indenture Act (if any) and the compliance certificate required
by Section 314(a) of the Trust Indenture Act in the form, in the manner and at
the times required by Section 314 of the Trust Indenture Act.  The Depositor and
the Administrative Trustees shall annually file with the Property Trustee a
certificate specifying whether such Person is in compliance with all of the
terms and covenants applicable to such Person hereunder.

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

  SECTION 8.18.  NUMBER OF ISSUER TRUSTEES.

     (a)  The number of Issuer Trustees shall be four, unless the Property
Trustee also acts as the Delaware Trustee, in which case the number of Issuer
Trustees may be three.

shall occur.  The vacancy shall be filled with an Issuer Trustee appointed in
accordance with Section 8.10.

     (c)  The death, resignation, retirement, removal, bankruptcy, incompetence
or incapacity to perform the duties of an Issuer Trustee shall not operate to

applicable law, delegate to any other natural person over the age of 21 his or
her power for the purpose of executing any documents contemplated in Section
2.7(a) or making any governmental filing; and

     (b)  The Administrative Trustees shall have power to delegate from time to
time to such of their number the doing of such things and the execution of such
instruments either in the name of the Issuer Trust or the names of the
Administrative Trustees or otherwise as the Administrative Trustees may deem
expedient, to the extent such delegation is not prohibited by applicable law or
contrary to the provisions of this Trust Agreement.

                                   ARTICLE 9
                      DISSOLUTION, LIQUIDATION AND MERGER

  SECTION 9.1.  DISSOLUTION UPON EXPIRATION DATE.

     Unless earlier dissolved, the Issuer Trust shall automatically dissolve,
and its affairs be wound up, on September 1, 2051 (the "EXPIRATION DATE"),
following the distribution of the Trust Property in accordance with Section 9.4.

  SECTION 9.2.  EARLY DISSOLUTION.

     The first to occur of any of the following events is an "EARLY DISSOLUTION
EVENT":

     (a)  the occurrence of a Depositor Bankruptcy Event in respect of, or the
dissolution or liquidation of, the Depositor, in its capacity as the Holder of
the Common Securities, unless

                                       45
<PAGE>

the Depositor shall transfer the Common Securities as provided by Section 5.10,
in which case this provision shall refer instead to any such successor Holder of
the Common Securities;

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

     (c)  the redemption of all of the Capital Securities in connection with the
redemption or repayment of all the Debentures; and

     (d)  the entry of an order for dissolution of the Issuer Trust by a court
of competent jurisdiction.

  SECTION 9.3.  DISSOLUTION.

     The respective obligations and responsibilities of the Issuer Trustees, the
Administrative Trustees and the Issuer Trust created and continued hereby shall
terminate upon the latest to occur of the following: (a) the distribution by the
Property Trustee to Holders of all amounts required to be distributed hereunder
upon the liquidation of the Issuer Trust pursuant to Section 9.4, or upon the
redemption of all of the Trust Securities pursuant to Section 4.2; (b) the
payment of any expenses owed by the Issuer Trust; and (c) the discharge of all
administrative duties of the Administrative Trustees, including the performance
of any tax reporting obligations with respect to the Issuer Trust or the
Holders.

  SECTION 9.4.  LIQUIDATION.

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

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

          (ii)   state the Liquidation Date;

          (iii)  state that from and after the Liquidation Date, the Trust
     Securities will no longer be deemed to be Outstanding and any Trust
     Securities Certificates not surrendered for exchange will be deemed to
     represent a Like Amount of Debentures, or if Section 9.4(d) applies, a
     right to receive a Liquidating Distribution; and

          (iv)   provide such information with respect to the mechanics by which
     Holders may exchange Trust Securities Certificates for Debentures, or if
     Section 9.4(d) applies,

                                       46
<PAGE>

     receive a Liquidation Distribution, as the Property Trustee (after
     consultation with the Administrative Trustees) shall deem appropriate.

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

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

     (d)  If, notwithstanding the other provisions of this Section 9.4, whether
because of an order for dissolution entered by a court of competent jurisdiction
or otherwise, distribution of the Debentures in the manner provided herein is
determined by the Property Trustee not to be practical, or if an Early
Dissolution Event specified in clause (c) of Section 9.2 occurs, the Trust
Property shall be liquidated, and the Issuer Trust shall be dissolved and its
affairs wound-up, 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 Issuer Trust, Holders will be entitled to receive out of the
assets of the Issuer Trust available for distribution to Holders, after
satisfaction of liabilities to creditors of the Issuer Trust as provided by
applicable law, an amount equal to the Liquidation Amount per Trust Security
plus accumulated and unpaid Distributions thereon to the date of payment (such
amount being the "LIQUIDATION DISTRIBUTION"). If, upon any such dissolution,
winding up or termination, the Liquidation Distribution can be paid only in part
because the Issuer Trust has insufficient assets available to pay in full the
aggregate Liquidation Distribution, then, subject to the next succeeding
sentence, the amounts payable by the Issuer Trust on the Trust Securities shall
be paid on a pro rata basis (based upon Liquidation Amounts). The Holders of the
Common Securities will be entitled to receive Liquidation Distributions upon any
such dissolution, winding-up or termination pro rata (determined as aforesaid)
with Holders of Capital Securities, except that, if a Debenture Event of Default
specified in Section 501(1) or 501(2) of the Indenture has occurred and is
continuing, the Capital Securities shall have a priority over the Common
Securities as provided in Section 4.3.

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

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

                           MISCELLANEOUS PROVISIONS

  SECTION 10.1.  LIMITATION OF RIGHTS OF HOLDERS.

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

  SECTION 10.2.  AMENDMENT.

     (a)  This Trust Agreement may be amended from time to time by the
Administrative Trustees and the Holders of all of the Common Securities, without
the consent of any Holder of the Capital Securities, (i) to cure any ambiguity,
correct or supplement any provision herein that may be inconsistent with any
other provision herein, or to make any other provisions with respect to matters
or questions arising under this Trust Agreement, which shall not be inconsistent
with the other provisions of this Trust Agreement, or (ii) to modify, eliminate
or add to any provisions of this Trust Agreement to such extent as shall be
necessary to ensure that the Issuer Trust will not be taxable as a corporation
or classified as other than a grantor trust for United States Federal income tax
purposes at all times that any Trust Securities are outstanding or to ensure
that the Issuer Trust will not be required to register as an "investment
company" under the Investment Company Act; provided, however, that in the case
of either clause (i) or (ii), such action shall not adversely affect in any
material respect the interests of any Holder.

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

     (c)  In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Holder (such consent being
obtained in accordance with Section 6.3 or 6.6 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 Holder to institute suit for the enforcement of
any such payment on or after such date; and notwithstanding any other provision
herein, without the unanimous consent of the Holders (such consent being
obtained in accordance with Section 6.3 or 6.6 hereof), this paragraph (c) of
this Section 10.2 may not be amended.

                                       49
<PAGE>

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

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

     (f)  Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Property Trustee, this Trust Agreement may not be
amended in a manner that imposes any additional obligation on the Property
Trustee.

     (g)  Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Delaware Trustee, this Trust Agreement may not be
amended in a manner that imposes any additional obligation on the Delaware
Trustee.

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

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

  SECTION 10.3.  SEPARABILITY.

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

  SECTION 10.4.  GOVERNING LAW.

     This Trust Agreement and the rights and obligations of each of the Holders,
the Issuer Trust, the Depositor, and the Issuer Trustees with respect to this
Trust Agreement and the Trust Securities shall be construed in accordance with
and governed by the laws of the State of Delaware without reference to its
conflicts of laws provisions.

  SECTION 10.5.  PAYMENTS DUE ON NON-BUSINESS DAY.

     If the date fixed for any payment on any Trust Security shall be a day that
is not a Business Day, then such payment need not be made on such date but may
be made on the next succeeding day that is a Business Day, with the same force
and effect as though made on the date

                                       50

Article Eight of the Indenture and pursuant to which the assignee agrees in
writing to perform the Depositor's obligations hereunder, the Depositor shall
not assign its obligations hereunder.

  SECTION 10.7.  HEADINGS.

     The Article and Section headings are for convenience only and shall not
affect the construction of this Trust Agreement.

  SECTION 10.8.  REPORTS, NOTICES AND DEMANDS.

purposes, upon hand delivery, mailing or transmission. Such notice, demand or
other communication to or upon the Depositor shall be deemed to have been
sufficiently given or made only upon actual receipt of the writing by the
Depositor.

by the Issuer Trust, the Property Trustee or such Administrative Trustee.

  SECTION 10.9.  AGREEMENT NOT TO PETITION.

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

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

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

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

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

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

     THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST THEREIN BY
OR ON BEHALF OF A HOLDER OR ANY BENEFICIAL OWNER, WITHOUT ANY SIGNATURE OR
FURTHER MANIFESTATION OF ASSENT, SHALL CONSTITUTE THE UNCONDITIONAL ACCEPTANCE
BY THE HOLDER AND ALL OTHERS HAVING A BENEFICIAL INTEREST IN SUCH TRUST SECURITY
OF ALL THE TERMS AND PROVISIONS OF THIS TRUST AGREEMENT, THE GUARANTEE AGREEMENT
AND THE INDENTURE, AND AGREEMENT TO THE SUBORDINATION PROVISIONS AND OTHER TERMS
OF THE GUARANTEE AGREEMENT AND THE

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