     shall be made on the next succeeding day that is a Business Day (and
     without any interest or other payment in respect of any such delay) except

     of such Distribution shall be made on the immediately preceding Business

     when due and assuming compliance by the Depositor and the Trust with their
     obligations under the Capital Securities Exchange and Registration Rights
     Agreement (and before giving effect to Additional Amounts, if applicable,
     or to Additional Distributions, if applicable), Distributions on the Trust
     Securities shall be payable at a rate of 8.09% per annum of the Liquidation
     Amount of the Trust Securities. The amount of Distributions payable for any
     full period shall be computed on the basis of a 360-day year of twelve 30-
     day months. The amount of Distributions for any partial period shall be
     computed on the basis of the number of days elapsed in a 360-day year of
     twelve 30-day months. The amount of Distributions payable for any period
     shall include the Additional Amounts, if any and the Additional
     Distributions, 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 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 on the relevant record date, which shall be
April 30 immediately preceding a Distribution Date which is on May 15, and
October 31 immediately preceding a Distribution Date which is on November 15.

     Section 4.2. Redemption.

     (a) On each Debenture Prepayment Date and on the stated maturity of the
Debentures, the Trust will be required to redeem, subject to Section 4.3, all
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 at such Holder's
address appearing in the Security Register. All notices of redemption shall
state:

               (i) the Redemption Date;

               (ii) the Redemption Price;

               (iii) the CUSIP number and;

               (iv) that on the Redemption Date the Redemption Price will become
     due and payable upon each such Trust Security and that Distributions
     thereon will cease to accrue on and after said date.

     (c) The Trust Securities shall be redeemed, if at all, at the applicable
Redemption Price with the proceeds from the contemporaneous prepayment or
repayment of Debentures. Redemptions of the Trust Securities shall be made and
the applicable Redemption Price shall be payable only to the extent that the
Trust has funds then on hand and available in the Payment Account for the
payment of such applicable Redemption Price.

                                       15

 
     (d) If the Property Trustee gives a notice of redemption in respect of the
Capital Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 4.2(c), with respect to Capital Securities held in 
book-entry form, the Property Trustee will irrevocably deposit with the Clearing
Agency 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 thereof. With respect to the Capital Securities
held in certificated form, the Property Trustee, subject to Section 4.2(c), will
irrevocably deposit with the Paying Agent 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 thereof upon surrender of
their Capital Securities Certificates. Notwithstanding the foregoing,
Distributions payable on or prior to the Redemption Date shall be payable to the
Holders of such Trust Securities as they appear on the Register for the Trust
Securities on the relevant record dates for the related Distribution Dates. If
notice of redemption shall have been given and funds deposited as required, then
upon the date of such deposit, all rights of Securityholders holding Trust
Securities will cease, except the right of such Securityholders to receive the
applicable Redemption Price and any Distribution payable 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 fixed for redemption is not a
Business Day, then payment of the applicable Redemption Price payable on such
date will be made on the next succeeding day that is a Business Day (and without
any interest or other payment in respect of any such delay), except that, if
such Business Day falls in the next calendar year, such payment will be made on
the immediately preceding Business Day, in each case, with the same force and
effect as if made on such date. In the event that payment of the applicable
Redemption Price is improperly withheld or refused and not paid either by the
Trust or by the Depositor pursuant to the Guarantee, Distributions on such Trust
Securities will continue to accrue, at the then applicable rate, from the
Redemption Date originally established by the Trust 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 applicable Redemption
Price.

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

     Section 4.3. Subordination of Common Securities.

     (a) Payment of Distributions (including Additional Amounts, if applicable,
and Additional Distributions, if applicable) on, and the Redemption Price of,
the Trust Securities, as applicable, shall be made pro rata among the Common
Securities and the Capital Securities based on the Liquidation Amount thereof;
provided, however, that if on any Distribution Date or Redemption Date any Event
of Default resulting from a Debenture Event of Default shall have occurred and
be continuing, no payment of any Distribution (including Additional Amounts, if
applicable, and Additional Distributions, if applicable) on, or Redemption Price
of, any Common Security, and no other payment on account of the redemption,
liquidation or other acquisition of Common Securities, shall be made unless
payment in full in cash of all accumulated and unpaid Distributions (including
Additional Amounts, if applicable) on all Outstanding 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, shall have been made or provided for, and all
funds immediately available to the Property Trustee shall first be applied to
the payment in full in cash of all Distributions (including Additional Amounts,
if applicable, and Additional Distributions, if applicable) on, or the
Redemption Price of, 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 Holder of Common Securities will be deemed
to have waived any right to act with respect to any such Event of Default under
this Trust Agreement until the effect of all such Events of Default with respect
to the Capital Securities have been cured, waived or otherwise eliminated. Until
any such Event of Default under this Trust Agreement with respect to the Capital
Securities has been so cured, waived or otherwise eliminated, the Property
Trustee shall act solely on behalf of the Holders of the Capital Securities and
not the Holder of the Common 

                                       16

 
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 Additional Amounts, if applicable, and
Additional Distributions, if applicable) in respect of the Capital Securities
shall be made by check mailed to the address of the Person entitled thereto as
such address shall appear on the Securities Register or, if the Capital
Securities are held by a Clearing Agency, such Distributions shall be made to
the Clearing Agency in immediately available funds, which shall credit the
relevant Persons' accounts at such Clearing Agency on the applicable
Distribution Dates. Payments in respect of the Common Securities shall be made
in such manner as shall be mutually agreed between the Property Trustee and the
Common Securityholder.

     Section 4.5. Tax Returns and Reports.

     The Administrative Agents shall prepare (or cause to be prepared), at the
Depositor's expense, and file all United States Federal, state and local tax and
information returns and reports required to be filed by or in respect of the
Trust. In this regard, the Administrative Agents shall (a) prepare and file (or
cause to be prepared and filed) the appropriate Internal Revenue Service Form
required to be filed in respect of the Trust in each taxable year of the Trust
and (b) prepare and furnish (or cause to be prepared and furnished) to each
Securityholder the appropriate Internal Revenue Service form required to be
provided on such form together with an annual financial statement of the Trust.
The Administrative Agents shall provide the Depositor and the Property Trustee
with a copy of all such returns and reports promptly after such filing or
furnishing. The Trustees shall comply with United States Federal withholding and
backup withholding tax laws and information reporting requirements with respect
to any payments to Securityholders under the Trust Securities.

     Section 4.6. Payment of Taxes, Duties, Etc. of the Trust.

     Upon receipt under the Debentures of Additional Sums, the Property Trustee
shall promptly pay any taxes, duties or governmental charges of whatsoever
nature (other than withholding taxes) imposed on the Trust by the United States
or any other taxing authority.

     Section 4.7. Payments under Indenture or Pursuant to Direct Actions.

     Notwithstanding any payments made to a Holder of Capital Securities (and
any Owner with respect thereto) pursuant to Section 5.8 of the Indenture or
Section 5.14 of this Trust Agreement, the Depositor shall remain obligated to
pay the principal of or interest on the Debentures, and the Depositor shall be
subrogated to the rights of the Holder (and Owner) of such Capital Securities
with respect to payments on the Capital Securities to the extent of any payments
made by the Depositor to such Holder (and Owner) pursuant to either of such
Sections.

                                  ARTICLE V.

                         Trust Securities Certificates

     Section 5.1. Initial Ownership.

     Upon the formation of the Trust and the contribution by the Depositor
pursuant to Section 2.3 and until the issuance of the Trust Securities, and at
any time during which no Trust Securities are outstanding, the Depositor shall
be the sole beneficial owner of the Trust.

                                       17

 
     Section 5.2. The Trust Securities Certificates.

     The Capital Securities Certificates shall be issued, and may be
transferred, only in blocks having not less than $100,000 Liquidation Amount
(100 Capital Securities), and the Common Securities Certificates shall be issued
in such denominations as may be necessary or appropriate. The Trust Securities
Certificates shall be executed on behalf of the Trust by manual signature of at
least one Administrative Agent. Trust Securities 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 Trust, shall be validly issued
and entitled to the benefits of this Trust Agreement, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
delivery of such Trust Securities Certificates or did not hold such offices at
the date of delivery of such Trust Securities Certificates. A transferee of a
Trust Securities Certificate shall become a Securityholder, and shall be
entitled to the rights and subject to the obligations of a Securityholder
hereunder, upon due registration of such Trust Securities Certificate in such
transferee's name pursuant to Sections 5.4, 5.11 and 5.13; provided that any
transfer, sale or other disposition of Capital Securities in a block having a
Liquidation Amount of less than $100,000 shall be deemed to be void and of no
legal effect whatsoever.

     Section 5.3. Execution and Delivery of Trust Securities Certificates.

     At the Closing Date, the Administrative Agents shall cause Trust Securities
Certificates, in an aggregate Liquidation Amount as provided in Sections 2.4 and
2.5, to be executed on behalf of the Trust and delivered to or upon the written
order of the Depositor, signed by its chairman of the board, its president, any
executive vice president or any vice president, treasurer or assistant treasurer
or controller without further corporate action by the Depositor, in authorized
denominations.

     Section 5.4. Registration of Transfer and Exchange of Capital Securities.

     (a) 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 and transfers and exchanges of Capital Securities
(the "Securities Register") in which, the registrar designated by the Depositor
(the "Securities Registrar"), subject to such reasonable regulations as it may
prescribe, shall provide for the registration of Capital Securities and Common
Securities (subject to Section 5.4(a)(1) in the case of Capital Securities and
Section 5.4(b) in the case of Private Capital Securities and Section 5.10 in the
case of the Common Securities) and registration of transfers and exchanges of
Capital Securities as herein provided. The Bank shall be the initial Securities
Registrar.

     Upon surrender for registration of transfer of any Capital Securities
Certificate at the office or agency maintained pursuant to Section 5.8 and
subject to compliance with Section 5.4(a)(1) in the case of Capital Securities
and Section 5.4(b) in the case of Private Capital Securities, the Administrative
Agents or any one of them shall execute 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 Agent or Agents.

     The Securities Registrar shall not be required to register the transfer of
any Capital Securities that have been called for redemption. At the option of a
Holder, Capital Securities may be exchanged for other Capital Securities 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 Agent and the
Securities Registrar duly executed by the Holder or his attorney duly authorized
in writing. Each Capital Securities Certificate 

                                       18

 
surrendered for registration of transfer or exchange shall be cancelled and
subsequently disposed of by an Administrative Agent in accordance with such
Person's customary practice.

     No service charge shall be made for any registration of transfer or
exchange of Capital Securities, 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.

               (1)  The Capital Securities will be issued, and may be
transferred, only in blocks having a Liquidation Amount of not less than
$100,000 (100 Capital Securities). Any transfer, sale or other disposition of
Capital Securities in a block having a Liquidation Amount of less than $100,000
shall be deemed to be void and of no legal effect whatsoever. Any such
transferee shall be deemed not to be the holder of such Capital Securities for
any purpose, including but not limited to the receipt of Distributions on such
Capital Securities, and such transferee shall be deemed to have no interest
whatsoever in such Capital Securities.

     (b)(1) In addition to the restrictions on transfer set forth in Sections
5.4(a)(1) and 5.4(b)(2), Beneficial ownership of every Private Capital Security
is subject to the restrictions on transfer imposed by the Securities Act and
rules and regulations promulgated by the Commission thereunder and each
certificate representing Private Capital Securities shall bear restrictive
legends (the "Securities Act Legends") substantially in the form attached as
Exhibit H hereto, unless such restrictions on transfer shall be terminated in
accordance with paragraph (b)(2) below. The Holder of each Private Capital
Security, by such Holder's acceptance thereof, agrees to be bound by such
restrictions on transfer.

     (b)(2) The restrictions imposed by the Securities Act and this paragraph
(b)(2) upon the transferability of any particular Private Capital Security shall
cease and terminate upon delivery by at least one Administrative Agent on behalf
of the Trust to the Property Trustee of an Officers' Certificate and Opinion of
Counsel stating that such Private Capital Security has been sold pursuant to an
effective registration statement under the Securities Act, exchanged for a
corresponding Liquidation Amount of the Exchange Capital Securities pursuant to
an effective registration statement under the Securities Act, or transferred in
compliance with Rule 144 under the Securities Act (or any successor provision
thereto). Any Private Capital Security as to which such Administrative Agent has
delivered to the Property Trustee an Officers' Certificate and Opinion of
Counsel that such restrictions on transfer shall have expired in accordance with
their terms or shall have terminated may, upon surrender of such Private Capital
Security for exchange to the Security Registrar or any Transfer Agent in
accordance with the provisions of this paragraph (b)(2) be exchanged for a new
Capital Security, of like tenor and aggregate Liquidation Amount, which shall
not bear the Securities Act Legends. The Administrative Agent shall inform the
Property Trustee in writing of the effective date of any registration statement
registering the Private Capital Securities or the Exchange Capital Securities
under the Securities Act. The Property Trustee shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the
aforementioned registration statement.

     As used in paragraph (a)(1) and in paragraphs (1) and (2) of this paragraph
(b), the term "transfer" encompasses any sale, pledge, transfer or other
disposition of any Private Capital Security.

     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 Agents 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 Agents, or any one of them, on behalf of the Trust shall execute
and make available for delivery, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Trust Securities Certificate, a new Trust
Securities Certificate of like class, tenor 

                                       19

 
and denomination. In connection with the issuance of any new Trust Securities
Certificate under this Section 5.5, the Administrative Agents 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
Trust, 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 Securityholders.

     The Trustees or the Securities Registrar shall treat the Person in whose
name any Trust Securities shall be registered in the Securities Register as the
owner of such Trust Securities for the purpose of receiving Distributions and
for all other purposes whatsoever, and neither the Trustees nor the Securities
Registrar shall be bound by any notice to the contrary.

     Section 5.7. Access to List of Securityholders' Names and Addresses.

     Each Holder and each Owner shall be deemed to have agreed not to hold the
Depositor, the Property Trustee or the Administrative Agents 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 or Agency.

     The Administrative Agents shall maintain 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 Trustees in respect of the Trust Securities Certificates may be served. The
Administrative Agents initially designate First Bank System, Inc., 601 Second
Avenue South, Minneapolis, Minnesota 55402 Attn: Treasurer, as its principal
corporate trust office for such purposes. The Administrative Agents shall give
prompt written notice to the Depositor and to the Securityholders of any change
in the location of the Securities Register or any such office or agency.

     Section 5.9. Appointment of Paying Agent.

     The Paying Agent shall make Distributions to Securityholders from the
Payment Account and shall report the amounts of such Distributions to the
Property Trustee and the Administrative Agents. Any Paying Agent shall have the
revocable power to withdraw funds from the Payment Account for the purpose of
making the Distributions referred to above. The Administrative Agents may revoke
such power and remove the Paying Agent if such Agents determine in their sole
discretion that the Paying Agent shall have failed to perform its obligations
under this Trust Agreement in any material respect. The Paying Agent shall
initially be the Bank, and any co-paying agent chosen by the Bank, and
acceptable to the Administrative Agents and the Depositor. Any Person acting as
Paying Agent shall be permitted to resign as Paying Agent upon 30 days' written
notice to the Administrative Agents, the Property Trustee and the Depositor. In
the event that the Bank shall no longer be the Paying Agent or a successor
Paying Agent shall resign or its authority to act be revoked, the Administrative
Agents shall appoint a successor that is acceptable to the Property Trustee and
the Depositor to act as Paying Agent (which shall be a bank or trust company).
The Administrative Agents shall cause such successor Paying Agent or any
additional Paying Agent appointed by the Administrative Agents to execute and
deliver to the Trustees an instrument in which such successor Paying Agent or
additional Paying Agent shall agree with the Trustees that as Paying Agent, such
successor Paying Agent or additional Paying Agent will hold all sums, if any,
held by it for payment to the Securityholders in trust for the benefit of the
Securityholders entitled thereto until such sums shall be paid to such
Securityholders. The Paying Agent shall return all unclaimed funds to the
Property Trustee and upon removal of a Paying Agent such Paying Agent shall also
return all funds in its possession to the Property Trustee. The provisions of
Sections 8.1, 

                                       20

 
8.3 and 8.6 herein shall apply to the Bank also in its role as Paying Agent, for
so long as the Bank 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 Closing Date, the Depositor shall acquire and 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 corporation, or any conveyance, transfer or lease by the
Depositor of its properties and assets substantially as an entirety to any
Person, pursuant to Section 8.1 of the Indenture, any attempted transfer of the
Common Securities shall be void. The Administrative Agents shall cause each
Common Securities Certificate issued to the Depositor to contain a legend
stating "THIS CERTIFICATE IS NOT TRANSFERABLE".

     Section 5.11.  Book Entry Interests.

     (a)  So long as Capital Securities are eligible for book-entry settlement
with the Clearing Agency or unless otherwise required by law, all Capital
Securities that are so eligible will be represented by one or more fully
registered Capital Security Certificates (each a "Global Certificate") in global
form to be delivered to the Clearing Agency, by, or on behalf of, the Trust.
Such Global Certificates shall initially be registered on the books and records
of the Trust in the name of Cede & Co., the nominee of The Depository Trust
Company, and no Owner will receive a definitive Capital Security Certificate
representing such Owner's interests in such Global Certificates, except as
provided in Section 5.11(e) below. The transfer and exchange of beneficial
interests in any such Capital Security in global form shall be effected through
the Clearing Agency in accordance with this Trust Agreement and the procedures
of the Clearing Agency therefor.

     (b)  Except as provided in subparagraph (e) of this Section 5.11,
beneficial owners of a Capital Security in global form shall not be entitled to
have certificates registered in their names, will not receive or be entitled to
receive physical delivery of certificates in definitive form and will not be
considered Holders of such Capital Security in global form.

     (c)  So long as the Capital Securities are eligible for book-entry
settlement, or unless otherwise required by law, upon any transfer of a
definitive Capital Security to a QIB in accordance with Rule 144A or to a Non-
U.S. Person in accordance with Regulation S, unless otherwise requested by the
transferor, and upon receipt of the definitive Capital Security or Capital
Securities being so transferred, together with a certification from the
transferor that the transfer is being made in compliance with Rule 144A (or
other evidence satisfactory to the Property Trustee on behalf of the Trust), the
Property Trustee on behalf of the Trust shall make an endorsement on the Book-
Entry Capital Securities Certificate to reflect an increase in the number of
Capital Securities represented by such Book-Entry Capital Securities Certificate
and the Property Trustee on behalf of the Trust shall cancel such definitive
Capital Security or Capital Securities in accordance with the standing
instructions and procedures of the Clearing Agency, the number of Capital
Securities represented by such Capital Security in global form to be increased
accordingly; provided that no definitive Capital Security, or portion thereof,
in respect of which the Trust or an Affiliate of the Trust held any beneficial
interest shall be included in such Capital Security in global form until such
definitive Capital Security is freely tradeable in accordance with Rule 144(k);
provided further that the Trust shall issue Capital Securities in definitive
form upon any transfer of a beneficial interest in the Capital Security in
global form to the Depositor or any Affiliate of the Depositor.

     (d)  Any Global Certificate may be endorsed with or have incorporated in
the text thereof such legends or recitals or changes not inconsistent with the
provisions of this Trust Agreement as may be required by the Clearing Agency, by
any national securities exchange or by the National Association of Securities
Dealers, Inc. in order for the Capital Securities to be tradeable on the PORTAL
Market or as may be required for the Capital Securities to be tradeable on any
other market developed for trading of securities pursuant to Rule 144A or
required to comply with any applicable law or any regulation thereunder or with
the rules and regulations of any securities exchange upon which the Capital
Securities may be listed or traded or to conform with any usage with respect
thereto, or to indicate any special limitations or restrictions to which any
particular Capital Securities are subject.

                                       21

 
     (e)  Notwithstanding any other provisions of this Trust Agreement (other
than the provisions set forth in this Section 5.11(e)), a Capital Security in
global form may not be exchanged in whole or in part for Capital Securities
registered, and no transfer of a Capital Security in global form may be
registered, in the name of any person other than the Clearing Agency or a
nominee thereof unless (i) such Clearing Agency (A) has notified the Property
Trustee that it is unwilling or unable to continue as Clearing Agency for such
global Capital Security or (B) has ceased to be a clearing agency registered as
such under the Exchange Act, (ii) there shall have occurred and be continuing an
Event of Default, or any event which after notice or lapse of time or both would
be an Event of Default under the Trust Agreement, with respect to such global
Capital Security, or (iii) pursuant to the following sentence. Subject to any
other applicable provisions hereof, all or any portion of a global Capital
Security may be exchanged for a Capital Security that has a like aggregate
liquidation amount and is not a global Capital Security, upon 20 days' prior
request made by the Clearing Agency or its authorized representative to the
Property Trustee. Following exchange of a global Capital Security, or a portion
thereof, for a definitive Capital Security, no such definitive Capital Security,
or portion thereof, shall be included in any Global Certificate except pursuant
to Section 5.11(c). 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 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 Certificates 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
     this Section 5.11 or 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.

     (b) Private Capital Securities initially purchased by Institutional
Accredited Investors will be issued only in certificated form.

     (c) The Private Capital Securities issued pursuant to Regulation S will be
represented by one or more Global Capital Securities in definitive, fully
registered form registered in the name of a nominee of DTC and deposited with
the Trustee, for the accounts of Euroclear and CEDEL. Until and including the
40th day after the latest of the commencement of the offering and the Closing
Date, beneficial interests in the Regulation S Capital Security may be held only
through Euroclear or CEDEL, unless delivery is made through the Restricted
Global Capital Security in accordance with certain certification requirements.

     (d) Exchange Capital Securities will be represented by one or more global
certificates registered in the name of Cede & Co. as the nominee of DTC.
Beneficial interests in the Exchange Capital Securities will be shown on, and
transfers thereof will be effected only through, records maintained by
participants in DTC.

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

                                       22

 
     Section 5.12. Notices to Clearing Agency.
     
     To the extent that a notice or other communication to the Owners is
required under this Trust Agreement, unless and until Definitive Capital
Securities Certificates shall have been issued to Owners pursuant to Section
5.13, the Trustees shall give all such notices and communications specified
herein to be given to Owners to the Clearing Agency, and shall have no
obligations to the Owners.

     Section 5.13. Procedures for Issuance of Definitive Capital Securities
Certificates.

     Upon surrender to the Administrative Agents of the Book Entry Capital
Securities Certificates by the Clearing Agency, accompanied by registration
instructions, the Administrative Agents, or any one of them, shall execute the
Definitive Capital Securities Certificates in accordance with the instructions
of the Clearing Agency. Neither the Securities Registrar nor the Trustees shall
be liable for any delay in delivery of such instructions and may conclusively
rely on, and shall be protected in relying on, such instructions. Upon the
issuance of Definitive Capital Securities Certificates, the Trustees shall
recognize the Holders in whose names Definitive Capital Securities Certificates
are registered as Securityholders. The Definitive Capital Securities
Certificates shall be printed, lithographed or engraved or may be produced in
any other manner as is reasonably acceptable to the Administrative Agents, as
evidenced by the execution thereof by the Administrative Agents or any one of
them.

     Section 5.14. Rights of Securityholders.

     (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement. The Trust Securities
shall have no preemptive or similar rights and when issued and delivered to
Securityholders against payment of the purchase price therefor will be fully
paid and nonassessable by the 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
Holders of at least 25% in Liquidation Amount of the Capital Securities then
Outstanding shall have such right by a notice in writing to the Depositor and
the Debenture Trustee; and upon any such declaration such principal amount of
and the accrued interest on all of the Debentures shall become immediately due
and payable, provided that the payment of principal and interest on such
Debentures shall remain subordinated to the extent provided in the Indenture.

     At any time after such 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 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 (including any
               Additional Interest (as defined in the Indenture)) on all of the
               Debentures,

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

                                       23

 
                         (C) 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 which has become
     due solely by such acceleration, have been cured or waived as provided in
     Section 5.13 of the Indenture.

     The holders of a majority in aggregate 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 which 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 the Capital
Securities all or part of which is represented by Book-Entry Capital Securities
Certificates, 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 which 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 which 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 5.1(1)
or 5.1(2) of the Indenture, any Holder of Capital Securities shall have the
right to institute a proceeding directly against the Depositor, pursuant to
Section 5.8 of the Indenture, for enforcement of payment to such Holder of the
principal amount of or interest on Debentures having a principal amount equal to
the 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.

                                  ARTICLE VI.

                   Acts of Securityholders; Meetings; Voting

     Section 6.1. Limitations on Voting Rights.

     (a) Except as provided in this Section, in Sections 5.14, 8.10 and 10.2 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 Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities, be construed so as to constitute the Securityholders
from time to time as partners or members of an association.

                                       24

 
     (b) So long as any Debentures are held by the Property Trustee, the
Trustees shall not (i) direct the time, method and place of conducting any
proceeding for any remedy available to the Debenture Trustee, or executing any
trust or power conferred on the Debenture Trustee with respect to such
Debentures, (ii) waive any past default which is waivable under Section 5.13 of
the Indenture, (iii) exercise any right to rescind or annul a declaration that
the principal of all the Debentures shall be due and payable or (iv) consent to
any amendment, modification or termination of the Indenture or the Debentures,
where such consent shall be required, without, in each case, obtaining the prior
approval of the Holders of at least a majority in Liquidation Amount of all
Outstanding 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 Trustees shall
not revoke any action previously authorized or approved by a vote of the Holders
of Capital Securities, except by a subsequent vote of the Holders of Capital
Securities. The Property Trustee shall notify all Holders of the Capital
Securities of any notice of default received from the Debenture Trustee with
respect to the Debentures. In addition to obtaining the foregoing approvals of
the Holders of the Capital Securities, prior to taking any of the foregoing
actions, the Trustees shall, at the expense of the Depositor, obtain an Opinion
of Counsel experienced in such matters to the effect that such action shall not
cause the Trust to fail to be classified as a grantor trust for United States
Federal income tax purposes.

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Trustees otherwise propose to effect, (i) any action that would adversely affect
in any material respect the powers, preferences or special rights of the Capital
Securities, whether by way of amendment to the Trust Agreement or otherwise, or
(ii) the dissolution, winding-up or termination of the Trust, other than
pursuant to the terms of this Trust Agreement, then the Holders of Outstanding
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
Outstanding 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 Trust to fail to be classified as a
grantor trust for United States Federal income tax purposes.

     Section 6.2. Notice of Meetings.

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

     Section 6.3. Meetings of Capital Securityholders.

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

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

     If a quorum is present at a meeting, an affirmative vote by more than a
majority of the Outstanding Capital Securities (based upon their Liquidation
Amount) held by the Capital Securityholders of record present, either in person
or by proxy, at such meeting shall constitute the action of the Securityholders,
unless this Trust Agreement requires a greater number of affirmative votes.

                                       25

 
     Section 6.4. Voting Rights.

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

     Section 6.5. Proxies, Etc.

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

     Section 6.6. Securityholder Action by Written Consent.

     Any action which may be taken by Securityholders at a meeting may be taken
without a meeting if Securityholders holding more than a majority of all
Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
vote in respect of such action (or such larger proportion thereof as shall be
required by any express provision of this Trust Agreement) shall consent to the
action in writing.

     Section 6.7. Record Date for Voting and Other Purposes.

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

     Section 6.8. Acts of Securityholders.

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

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

                                       26

 
such instrument or writing, or the authority of the Person executing the same,
may also be proved in any other manner which any Trustee receiving the same
deems sufficient.

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

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

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

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

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

     Section 6.9. Inspection of Records.

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

Trust or would question the right, power and authority of the Property Trustee
or the 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
Securityholders that:

                                       28

 
                                 ARTICLE VIII.

                                 The Trustees

     Section 8.1. Certain Duties and Responsibilities.

     (a) The duties and responsibilities of the Trustees shall be as provided by
this Trust Agreement and, in the case of the Property Trustee, by the Trust
Indenture Act. Notwithstanding the foregoing, no provision of this Trust
Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it. Whether or not therein expressly so provided, every provision of this Trust
Agreement relating to the conduct or affecting the liability of or affording
protection to the Trustees shall be subject to the provisions of this Section.
Nothing in this Trust Agreement shall be construed to release the Delaware
Trustee or an Administrative Agent from liability for its own gross negligent
action, its own gross negligent failure to act, or its own willful misconduct.
To the extent that, at law or in equity, the Delaware Trustee or an
Administrative Agent has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to the Securityholders, such Administrative
Agent shall not be liable to the Trust or to any Securityholder for such
Trustee's good faith reliance on the provisions of this Trust Agreement. The
provisions of this Trust Agreement, to the extent that they restrict the duties
and liabilities of the Delaware Trustee or the Administrative Agent otherwise
existing at law or in equity, are agreed by the Depositor and the
Securityholders to replace such other duties and liabilities of the Delaware
Trustee or the Administrative Agents.

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

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

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

               (ii) the Property Trustee shall not be liable with respect to any
     action taken or omitted to be taken by it in good faith in accordance with
     the direction of the Holders of not less than a majority in Liquidation
     Amount of the Trust Securities relating to the time, method and place of
     conducting any proceeding for any remedy available to the Property Trustee,
     or exercising any trust or power conferred upon the Property Trustee under
     this Trust Agreement;

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

               (iv) the Property Trustee shall not be liable for any interest on
     any money received by it except as it may otherwise agree with the
     Depositor; and money held by the Property Trustee need not be segregated

                                       29

 
     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; and

               (v) the Property Trustee shall not be responsible for monitoring
     the compliance by the Administrative Agents or the Depositor with their
     respective duties under this Trust Agreement, nor shall the Property
     Trustee be liable for the default or misconduct of the Administrative
     Agents or the Depositor.

     Section 8.2. Certain Notices.

     Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 10.8, notice of such Event of
Default to the Securityholders, the Administrative Agents and the Depositor,
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 Administrative Agent shall transmit, in the
manner and to the extent provided in Section 10.8, notice of such exercise to
the Securityholders and the Property Trustee, unless such exercise shall have
been revoked.

     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 or
(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 Capital Securityholders are entitled to vote under the terms of this Trust
Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting written instructions of the Depositor as to the course of action to
be taken and the Property Trustee shall take such action, or refrain from taking
such action, as the Property Trustee shall be instructed in writing to take, or
to refrain from taking, by the Depositor; provided, however, that if the
Property Trustee does not receive such instructions of the Depositor within ten
Business Days after it has delivered such notice, or such reasonably shorter
period of time set forth in such notice (which to the extent practicable shall
not be less than two Business Days), it may, but shall be under no duty to, take
or refrain from taking such action not inconsistent with this Trust Agreement as
it shall deem advisable and in the best interests of the Securityholders, in
which event the Property Trustee shall have no liability except for its own bad
faith, negligence or willful misconduct;

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

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

                                       30

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

     (f)  the Property Trustee may consult with counsel (which counsel may be
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, such counsel may be counsel to the Depositor or any of its
Affiliates, and may include any of its employees; the Property Trustee shall
have the right at any time to seek instructions concerning the administration of
this Trust Agreement from any court of competent jurisdiction;

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

     (h)  the Property Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, approval, bond,
debenture, note or other evidence of indebtedness or other paper or document,
unless requested in writing to do so by one or more Securityholders, but the
Property Trustee may make such further inquiry or investigation into such facts
or matters as it may see fit;

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

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

     (k)  except as otherwise expressly provided by this Trust Agreement, the
Property Trustee shall not be under any obligation to take any action that is
discretionary under the provisions of this Trust Agreement.

     No provision of this Trust Agreement shall be deemed to impose any duty or
obligation on the Property Trustee to perform any act or acts or exercise any
right, power, duty or obligation conferred or imposed on it, in any jurisdiction
in which it shall be illegal, or in which the Property Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any
such act or acts, or to exercise any such right, power, duty or obligation. No
permissive power or authority available to the Property Trustee shall be
construed to be a duty.

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

     Section 8.5. May Hold Securities.

     Except as provided in the definition of the term "Outstanding" in Article
I, any Trustee or any other agent of any Trustee or the Trust, in its individual
or any other capacity, may become the owner or pledgee of Trust 

                                       31

 
Securities and, subject to Sections 8.8 and 8.13, may otherwise deal with the
Trust with the same rights it would have if it were not a Trustee or such other
agent.

     Section 8.6. Compensation; Indemnity; Fees.

     (a)  The Depositor agrees:

          (i)   to pay to the Trustees from time to time compensation for all
     services rendered by them hereunder (which compensation shall not be
     limited by any provision of law in regard to the compensation of a trustee
     of an express trust) as specified in a separate agreement between any of
     the Trustees and the Depositor;

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

          (iii) to the fullest extent permitted by applicable law, to indemnify
     and hold harmless (w) each Trustee, (x) any Affiliate of any Trustee, (y)
     any officer, director, shareholder, employee, representative or agent of
     any Trustee, and (z) any employee or agent of the Trust or its Affiliates,
     (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 termination of the Trust or any act or omission performed or
     omitted by such Indemnified Person in good faith on behalf of the 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 or willful misconduct with
     respect to such acts or omissions.

     (b)  In furtherance of the foregoing, the Depositor hereby agrees, whether
or not any of the transactions contemplated by the Trust Agreement shall be
consummated, to assume liability for, and hereby indemnifies, protects, saves
and keeps harmless the Property Trustee, the Delaware Trustee and each of its
respective officers, directors, successors, assigns, legal representatives,
agents and servants (each an "ERISA Indemnified Person"), from and against any
and all liabilities, obligations, losses, damages, penalties, taxes (excluding
any taxes payable by the Bank on or measured by any compensation received by the
Bank for its services as trustee), claims, actions, investigations, proceedings,
costs, expenses or disbursements (including, without limitation, reasonable
legal fees and expenses) of any kind and nature whatsoever which may be imposed
on, incurred by or asserted at any time against an ERISA Indemnified Person
(whether or not also indemnified against by any other person) in any way
relating to or arising out of (i) the assets of the Trust being deemed to be
"plan assets" within the meaning of Department of Labor Regulations Section
2510.3-101 (ERISA), (ii) any violation by the Trust, any Trustee or the
Depositor of the prohibited transaction rules under the Employee Retirement
Income Security Act of 1974, as amended ("ERISA") or any excise taxes under
Section 4975 of the Code and (iii) the application of the fiduciary investment
standards of ERISA to the Trust, any Trustee or the Depositor.

     (c)  In case any such action, investigation or proceeding shall be brought
involving an ERISA Indemnified Person, Depositor shall assume the defense
thereof, including the employment of counsel and the payment of all expenses.
The ERISA Indemnified Person shall have the right to employ separate counsel in
any such action, investigation or proceeding and to participate in the defense
thereof, but the reasonable counsel fees and expenses of such counsel shall be
paid by Depositor.

     (d)  If the indemnification provided for herein is invalid or unenforceable
in accordance with its terms, then Depositor shall contribute to the amount paid
or payable by an ERISA Indemnified Person as a result of such liability in such
proportion as is appropriate to reflect the relative benefits received by
Depositor on one hand and the 

                                       32

 
ERISA Indemnified Persons on the other from the transactions contemplated by the
Trust Agreement. For this purpose, the benefits received by Depositor shall be
the aggregate value of the Trust assets, and the benefits received by the ERISA
Indemnified Persons shall be its fees as trustee less costs and unreimbursed
expenses incurred by it as trustee in relation to the Trust. If, however, the
allocation provided by the immediately preceding two sentences is not permitted
by applicable law, then Depositor shall contribute to such amount paid or
payable by an ERISA Indemnified Person in such proportion as is appropriate to
reflect not only such relative benefits but also the relative fault of Depositor
on the one hand and the ERISA Indemnified Person on the other in connection with
the actions or omissions which resulted in such liability, as well as any other
relevant equitable considerations.

     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement.

     The Depositor and any 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 Trust, and the 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 Trust, shall not be deemed wrongful or improper. Neither the
Depositor, nor any Trustee, shall be obligated to present any particular
investment or other opportunity to the Trust even if such opportunity is of a
character that, if presented to the Trust, could be taken by the Trust, and the
Depositor or any Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity. Any 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 Trustees.

     (a)  There shall at all times be a Property Trustee hereunder with respect
to the Trust Securities. The Property Trustee shall be a Person that is eligible
pursuant to the Trust Indenture Act to act as such and has a combined capital
and surplus of at least $50,000,000. If any such Person publishes reports of
condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section
8.7(a), 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(a), it shall resign immediately in the manner and with the
effect hereinafter specified in this Article.

     (b)  There shall at all times be one or more Administrative Agents
hereunder with respect to the Trust Securities. Each Administrative Agent shall
be either a natural person who is at least 21 years of age or a legal entity
that shall act through one or more persons authorized to bind that entity.

     (c)  There shall at all times be a Delaware Trustee with respect to the
Trust Securities. The Delaware Trustee shall either be (i) a natural person who
is at least 21 years of age and a resident of the State of Delaware or (ii) a
legal entity with its principal place of business in the State of Delaware and
that otherwise meets the requirements of applicable Delaware law that shall act
through one or more persons authorized to bind such entity.

     Section 8.8. Conflicting Interests.

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

     Section 8.9. Co-Trustees and Separate Trustee.

     Unless an Event of Default shall have occurred and be continuing, at any
time or times, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the Trust Property may
at the time be located, the Depositor and the Administrative Agents, by agreed
action of the majority 

                                       33

 
of such Trustees, shall have power to appoint, and upon the written request of
the Administrative Agents, the Depositor shall for such purpose join with the
Administrative Agents in the execution, delivery, and performance of all
instruments and agreements necessary or proper to appoint, one or more Persons
approved by the Property Trustee either to act as co-trustee, jointly with the
Property Trustee, of all or any part of such Trust Property, or to the extent
required by law to act as separate trustee of any such property, in either case
with such powers as may be provided in the instrument of appointment, and to
vest in such Person or Persons in the capacity aforesaid, any property, title,
right or power deemed necessary or desirable, subject to the other provisions of
this Section 8.9. If the Depositor does not join in such appointment within 15
days after the receipt by it of a request so to do, or in case a Debenture Event
of Default has occurred and is continuing, the Property Trustee alone shall have
power to make such appointment. Any co-trustee or separate trustee appointed
pursuant to this Section 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 and delivered and all rights,
powers, duties, and obligations hereunder in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Trustees specified hereunder, shall be exercised,
solely by such Trustees and not by such co-trustee or separate trustee.

     (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 Trustee in the execution, delivery and performance of all
instruments and agreements necessary or proper to effectuate such resignation or
removal. A successor to any co-trustee or separate trustee so resigned or
removed may be appointed in the manner provided in this Section.

     (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.

                                       34

 
     Section 8.10. Resignation and Removal; Appointment of Successor.

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

     Subject to the immediately preceding paragraph, the Relevant Trustee may
resign at any time by giving written notice thereof to the Holder of the Common
Securities. If the instrument of acceptance by the successor Trustee required by
Section 8.11 shall not have been delivered to the Relevant Trustee within 30
days after the giving of such notice of resignation, the Relevant Trustee may
petition, at the expense of the Trust, any court of competent jurisdiction for
the appointment of a successor Relevant Trustee.

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

     If any Trustee shall resign, be removed or become incapable of acting as
Trustee, or if a vacancy shall occur in the office of any Trustee for any cause,
at a time when no Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees, and the retiring Trustee shall comply with the applicable requirements
of Section 8.11. If the Property Trustee or the Delaware Trustee shall resign,
be removed or become incapable of continuing to act as the Property Trustee or
the Delaware Trustee, as the case may be, at a time when a Debenture Event of
Default shall have occurred and be continuing, the Capital Securityholders, by
Act of the Securityholders of a majority in Liquidation Amount of the Capital
Securities then Outstanding delivered to the retiring Relevant Trustee, shall
promptly appoint a successor Relevant Trustee or Trustees, and such successor
Trustee shall comply with the applicable requirements of Section 8.11. If an
Administrative Agent shall resign, be removed or become incapable of acting as
Administrative Agent, the Common Securityholder by Act of the Common
Securityholder delivered to the Administrative Agent shall promptly appoint a
successor Administrative Agent or Administrative Agents and such successor
Administrative Agent or Agents shall comply with the applicable requirements of
Section 8.11. If no successor Relevant Trustee shall have been so appointed by
the Common Securityholder or the Capital Securityholders and accepted
appointment in the manner required by Section 8.11, any Securityholder who has
been a Securityholder of Trust Securities for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Relevant Trustee.

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

     Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Agent or a Delaware Trustee who is a
natural person dies or becomes, in the opinion of the Depositor, incompetent or
incapacitated, the vacancy created by such death, incompetence or incapacity may
be filled by (a) the unanimous act of the remaining Administrative Agents if
there are at least two of them or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Agents or Delaware Trustee, as the case may be, set forth in
Section 8.7).

     Section 8.11. Acceptance of Appointment by Successor.

     In case of the appointment hereunder of a successor Trustee such successor
Trustee so appointed shall execute, acknowledge and deliver to the Trust and to
the retiring Trustee an instrument accepting such appointment, 

                                       35

 
and thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on the request of the Depositor or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee and if the Property Trustee is the
resigning Trustee shall duly assign, transfer and deliver to the successor
Trustee all property and money held by such retiring Property Trustee hereunder.

     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 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 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; but,
on request of the Trust or any successor Relevant Trustee such retiring Relevant
Trustee shall duly assign, transfer and deliver to such successor Relevant
Trustee all Trust Property, all proceeds thereof and money held by such retiring
Relevant Trustee hereunder with respect to the Trust Securities and the Trust.

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

     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.

     Section 8.12. Merger, Conversion, Consolidation or Succession to Business.

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

     Section 8.13. Preferential Collection of Claims Against Depositor or
Trust.

     In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Trust or any other obligor upon the
Trust Securities or the property of the 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 as therein expressed or by
declaration or otherwise and irrespective of whether the Property Trustee shall
have made any demand on the 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

                                       36

 
     (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 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 8.14. Reports by Property Trustee.

     (a)  Not later than July 15 of each year commencing with July 15, 1997, the
Property Trustee shall transmit to all Securityholders in accordance with
Section 10.8, and to the Depositor, a brief report dated as of the immediately
preceding December 31 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;

          (ii)   a statement that the Property Trustee has complied with all of
     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 December 31 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 Securityholders
such reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant thereto.

     (c)  A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Property Trustee with each national stock exchange,
the Nasdaq National Market or such other interdealer quotation system or self-
regulatory organization upon which the Trust Securities are listed or traded, if
any, with the Commission and with the Depositor.

     Section 8.15. Reports to the Property Trustee.

     The Depositor and the Administrative Agents on behalf of the Trust shall
provide to the Property Trustee and the Holders 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.

     Section 8.16. Evidence of Compliance with Conditions Precedent.

     Each of the Depositor and the Administrative Agents on behalf of the
Trust shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement that relate
to any of the matters set forth in Section 314 (c) of the Trust Indenture Act.
Any certificate or opinion required 

                                       37

 
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 8.17 Number of Trustees.

     (a)  The number of Trustees shall be five, provided that the Holder of all
of the Common Securities by written instrument may increase or decrease the
number of Administrative Agents. The Property Trustee and the Delaware Trustee
may be the same Person.

     (b)  If a Trustee ceases to hold office for any reason and the number of
Administrative Agents is not reduced pursuant to Section 8.17(a), or if the
number of Trustees is increased pursuant to Section 8.17(a), a vacancy shall
occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 8.10.

     (c)  The death, resignation, retirement, removal, bankruptcy, incompetence
or incapacity to perform the duties of a Trustee shall not operate to annul the
Trust. Whenever a vacancy in the number of Administrative Agents shall occur,
until such vacancy is filled by the appointment of an Administrative Agent in
accordance with Section 8.10, the Administrative Agents in office, regardless of
their number (and notwithstanding any other provision of this Agreement), shall
have all the powers granted to the Administrative Agents and shall discharge all
the duties imposed upon the Administrative Agents by this Trust Agreement.

     Section 8.18. Delegation of Power.

     (a)  Any Administrative Agent may, by power of attorney consistent with
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), including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing; and

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

                                  ARTICLE IX.

                      Termination, Liquidation and Merger

     Section 9.1. Termination Upon Expiration Date.

     Unless earlier dissolved, the Trust shall automatically dissolve on
November 6, 2027 (the "Expiration Date"), following the distribution of the
Trust Property in accordance with Section 9.4.

     Section 9.2. Early Termination.

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

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

     (b)  the written direction to the Property Trustee from the Depositor at
any time to dissolve the Trust and distribute Debentures to Securityholders in
exchange for the Like Amount of the Trust Securities (which direction is
optional and wholly within the discretion of the Depositor).

                                       38

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

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

     Section 9.3. Termination.

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

     Section 9.4. Liquidation.

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

               (i)   state the Liquidation Date;

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

               (iii) provide such information with respect to the mechanics by
     which Holders may exchange Trust Securities Certificates for certificates
     representing the Like Amount of the Debentures, or if Section 9.4(d)
     applies receive a Liquidation Distribution, as the Administrative Agents or
     the Property Trustee shall deem appropriate.

     (b)  Except where Section 9.2(c) or 9.4(d) applies, in order to effect the
liquidation of the Trust and distribution of the Debentures to Securityholders,
the Administrative Agents shall establish a record date for such distribution
(which shall be not more than 45 days prior to the Liquidation Date) and,
through the appointment of a separate exchange agent, shall establish such
procedures as it shall deem appropriate to effect the distribution of Debentures
in exchange for the Outstanding Trust Securities.

     (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
Administrative Agents or their agent for exchange, (iii) the Depositor shall use
its best efforts to have the Debentures listed on the New York Stock Exchange or
on such other exchange, interdealer quotation system or self-regulatory
organization as the Capital Securities are then listed, if any, (iv) any Trust
Securities Certificates not so surrendered for exchange will be deemed to
represent a Like Amount of Debentures, accruing interest at the rate provided
for in the Debentures from the last Distribution Date on which a Distribution
was made on the related Trust Securities 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 Debentures represented by such
Certificates) and (v) all rights of Securityholders holding Trust Securities
will cease, except the right of such Securityholders to receive the Like Amount
of Debentures upon surrender of Trust Securities Certificates.

                                       39

 
     (d)  In the event that, 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 Administrative Agents not to be
practical, the Trust Property shall be liquidated, and the Trust shall be
dissolved, wound-up or terminated, by the Administrative Agents in such manner
as the Administrative Agents determine. In such event, on the date of the
dissolution, winding-up or other termination of the Trust, Securityholders will
be entitled to receive out of the assets of the Trust available for distribution
to Securityholders, after satisfaction of liabilities to creditors of the Trust
as provided by applicable law, an amount equal to the Liquidation Amount per
Trust Security plus accumulated and unpaid Distributions thereon to the date of
payment (such amount being the "Liquidation Distribution"). If, upon any such
dissolution, winding up or termination, the Liquidation Distribution can be paid
only in part because the Trust has insufficient assets available to pay in full
the aggregate Liquidation Distribution, then, subject to the next succeeding
sentence, the amounts payable by the Trust on the Trust Securities shall be paid
on a pro rata basis (based upon Liquidation Amounts). The holder of the Common
Securities 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 has
occurred and is continuing, the Holders of Capital Securities shall have a
priority over the Holders of Common Securities.

     Section 9.5. Mergers, Consolidations, Amalgamations or Replacements of
the Trust.

     The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except pursuant
to this Section 9.5. At the request of the Depositor, with the consent of the
Administrative Agents and without the consent of the Holders of the Capital
Securities, the Property Trustee or the Delaware Trustee, the 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 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 rank the same
as the Capital Securities rank in priority with respect to distributions and
payments upon liquidation, redemption and otherwise, (ii) the Depositor
expressly appoints a trustee of such successor entity possessing the same powers
and duties as the Property Trustee as the holder of the Debentures, (iii) the
Successor Securities are listed or traded, or any Successor Securities will be
listed upon notification of issuance, on any national securities exchange or
other organization on which the Capital Securities are then listed or traded, if
any, (iv) 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, (v) 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, (vi) such successor entity has a purpose
identical to that of the Trust, (vii) prior to such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease, the Depositor has
received an Opinion of Counsel to the effect that (a) such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely affect the rights, preferences and privileges of the holders of the
Capital Securities (including any Successor Securities) in any material respect,
and (b) following such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, neither the Trust nor such successor entity will
be required to register as an investment company under the 1940 Act and (viii)
the Depositor owns all of the Common Securities of such successor entity and
guarantees the obligations of such successor entity under the Successor
Securities at least to the extent provided by the Guarantee. Notwithstanding the
foregoing, the Trust shall not, except with the consent of holders of 100% in
Liquidation Amount of the 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 Trust or the successor entity to be classified as other than a
grantor trust for United States Federal income tax purposes.

                           Miscellaneous Provisions

     Section 10.1. Limitation of Rights of Securityholders.

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

     Section 10.2. Amendment.

     (a)  This Trust Agreement may be amended from time to time by the
Property Trustee, the Administrative Agents and the Depositor, without the
consent of any Securityholders, (i) to cure any ambiguity, correct or supplement
any provision herein which may be inconsistent with any other provision herein,
or to make any other provisions with respect to matters or questions arising
under this Trust Agreement, 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 Trust will be classified for United States Federal income tax
purposes as a grantor trust at all times that any Trust Securities are
outstanding or to ensure that the Trust will not be required to register as an
investment company under the 1940 Act; provided, however, that in the case of
clause (i), such action shall not adversely affect in any material respect the
interests of any Securityholder, and any amendments of this Trust Agreement
shall become effective when notice thereof is given to the Securityholders.

     (b)  Except as provided in Section 10.2(c) hereof, any provision of
this Trust Agreement may be amended by the Trustees and the Depositor with (i)
the consent of Trust Securityholders representing not less than a majority
(based upon Liquidation Amounts) of the Trust Securities then Outstanding and
(ii) receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status as a grantor trust for
United States Federal income tax purposes or the Trust's exemption from status
of an investment company under the 1940 Act.

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

     (d)  Notwithstanding any other provisions of this Trust Agreement, the
Depositor shall not enter into or consent to any amendment to this Trust
Agreement which would cause the Trust to fail or cease to qualify for the
exemption from status of an investment company under the 1940 Act or fail or
cease to be classified as a grantor trust for United States Federal income tax
purposes.

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

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

                                       41

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

     Section 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
SECURITYHOLDERS, THE TRUST AND THE 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.

     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 (except as otherwise
provided in Sections 4.1(a) and 4.2(d)), with the same force and effect as
though made on the date fixed for such payment, and no interest shall accrue
thereon for the period after such date.

     Section 10.6. Successors.

     This Trust Agreement shall be binding upon and shall inure to the
benefit of any successor to the Depositor, the Trust or the Relevant Trustee,
including any successor by operation of law. Except in connection with a
consolidation, merger or sale involving the Depositor that is permitted under
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.

any Securityholder or the Depositor may be given or served in writing by deposit
thereof, first-class postage prepaid, in the United States mail, hand delivery
or facsimile transmission, in each case, addressed, (a) in the case of a Capital

notice, demand or other communication to or upon a Securityholder shall be
deemed to have been sufficiently given or made, for all purposes, upon hand
delivery, mailing or transmission.

     Any notice, demand or other communication which by any provision of this
Trust Agreement is required or permitted to be given or served to or upon the
Trust, the Property Trustee, the Delaware Trustee or the 

                                       42

 
Administrative Agents shall be given in writing addressed (until another address

     Section 10.9 Agreement Not to Petition.

     Each of the Trustees and the Depositor agree for the benefit of the
Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any Bankruptcy Law or
otherwise join in the commencement of any proceeding against the Trust under any
Bankruptcy Law. In the event the Depositor takes action in violation of this
Section 10.9, the Property Trustee agrees, for the benefit of Securityholders,
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 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 Trustee or the Trust may assert. The provisions of this Section
10.9 shall survive the termination of this Trust Agreement.

     Section 10.10 Trust Indenture Act; Conflict with Trust Indenture Act.

for the purposes of the Trust Indenture Act.

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

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

     Section 10.11 Acceptance of Terms of Trust Agreement, Guarantee and
Indenture.

     THE RECEIPT AND ACCEPTANCE OF A TRUST SECURITY OR ANY INTEREST THEREIN BY

     This Capital Security is a Global Certificate within the meaning of the
Trust Agreement hereinafter referred to and is registered in the name of The
Depository Trust Company (the "Depository") or a nominee of the Depository. This
Capital Security is exchangeable for Capital Securities registered in the name
of a person other than the Depository or its nominee only in the limited
circumstances described in the Trust Agreement and no transfer of this Capital
Security (other than a transfer of this Capital Security as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository) may be registered except in
limited circumstances.

     Unless this Capital Security is presented by an authorized representative
of The Depository Trust Company (55 Water Street, New York) to FBS Capital I or
its agent for registration of transfer, exchange or payment, and any Capital
Security issued is registered in the name of Cede & Co. or such other name as
requested by an authorized representative of The Depository Trust Company and
any payment hereon is made to Cede & Co. or such other entity as is requested by
an authorized representative of DTC, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY A PERSON IS WRONGFUL inasmuch as the registered owner
hereof, Cede & Co., has an interest herein.

               THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER
     THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT") AND MAY
     NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT (A) BY THE
     INITIAL INVESTOR (1) TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A
     QUALIFIED INSTITUTIONAL BUYER WITHIN THE MEANING OF RULE 144A UNDER THE
     SECURITIES ACT PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A
     QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF
     RULE 144A, (2) IN AN OFFSHORE TRANSACTION COMPLYING WITH RULE 903 OR RULE
     904 OF REGULATION S UNDER THE SECURITIES ACT, (3) PURSUANT TO AN EXEMPTION
     FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER
     (IF AVAILABLE) OR (4) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER
     THE SECURITIES ACT AND (B) BY SUBSEQUENT INVESTORS AS SET FORTH IN (A)
     ABOVE OR TO AN INSTITUTIONAL ACCREDITED INVESTOR IN A TRANSACTION EXEMPT
     FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, IN EACH CASE (A)
     AND (B) IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAW OF THE STATES OF
     THE UNITED STATES AND OTHER JURISDICTIONS.

     THE CAPITAL SECURITIES WILL BE ISSUED, AND MAY BE TRANSFERRED, ONLY IN
     BLOCKS HAVING A LIQUIDATION AMOUNT OF NOT LESS THAN $100,000 (100 CAPITAL
     SECURITIES).  ANY TRANSFER, SALE OR OTHER DISPOSITION OF CAPITAL SECURITIES
     IN A BLOCK HAVING A LIQUIDATION AMOUNT OF LESS THAN $100,000 SHALL BE
     DEEMED TO BE VOID AND OF NO LEGAL EFFECT WHATSOEVER.  ANY SUCH TRANSFEREE
     SHALL BE DEEMED NOT TO BE THE HOLDER OF SUCH CAPITAL SECURITIES FOR ANY
     PURPOSE, INCLUDING BUT NOT LIMITED TO THE RECEIPT OF DISTRIBUTIONS ON SUCH
     CAPITAL SECURITIES, AND SUCH TRANSFEREE SHALL BE DEEMED TO HAVE NO INTEREST
     WHATSOEVER IN SUCH CAPITAL SECURITIES.

Attention:     Declan Lewis

Re:   FBS Capital I 8.09% Capital Securities

Ladies and Gentlemen:

     The purpose of this letter is to set forth certain matters relating to the
issuance and deposit with The Depository Trust Company ("DTC") of the 8.09%
Capital Securities (the "Capital Securities"), of FBS Capital I, a Delaware
business trust (the "Issuer"), formed pursuant to a Trust Agreement between
First Bank System, Inc. ("FBS") and Wilmington Trust Company, as Property
Trustee, Wilmington Trust Company, as Delaware Trustee, and the Administrative
Agents named therein. The payment of distributions on the Capital Securities,
and payments due upon liquidation of Issuer or redemption of the Capital
Securities, to the extent the Issuer has funds available for the payment thereof
are guaranteed by FBS to the extent set forth in a Guarantee Agreement dated
November 26, 1996 by FBS with respect to the Capital Securities. FBS and the
Issuer propose to sell the Capital Securities to Goldman, Sachs & Co., Lehman
Brothers, Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan
Stanley & Co. Incorporated, Dain Bosworth Incorporated and Piper Jaffray Inc.
(collectively, the "Initial Purchasers") pursuant to a Purchase Agreement dated
November 19, 1996 by and among the Initial Purchasers, the Issuer and FBS and
the Initial Purchasers wish to take delivery of the Capital Securities through
DTC. Wilmington Trust Company is acting as transfer agent and registrar with
respect to the Capital Securities (the "Transfer Agent and Registrar").

     To induce DTC to accept the Capital Securities as eligible for deposit at
DTC, and to act in accordance with DTC's rules with respect to the Capital
Securities, the Issuer, the Transfer Agent and Registrar and DTC agree among
each other as follows:

     1. Prior to the closing of the sale of the Capital Securities to the
Initial Purchasers, which is expected to occur on or about November 26, 1996,
there shall be deposited with DTC one or more global certificates (individually
and collectively, the "Global Certificate") registered in the name of DTC's
Capital Securities nominee, Cede & Co., representing an aggregate of 300,000
Capital Securities and bearing the following legend:

          Unless this certificate is presented by an authorized representative
          of The Depository Trust Company, a New York corporation ("DTC"), to
          Issuer or its agent for registration of transfer, exchange, or
          payment, and any certificate issued is registered in the name of Cede
          & Co. or in such other name as is requested by an authorized
          representative of DTC (and any payment is made to Cede & Co. or to
          such other entity as is requested by an authorized representative of
          DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE
          BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner
          hereof, Cede & Co., has an interest herein.

     2. The Amended and Restated Trust Agreement of the Issuer provides for the
voting by holders of the Capital Securities under certain limited circumstances.
The Issuer shall establish a record date for such purposes and shall, to the
extent possible, give DTC notice of such record date not less than 15 calendar
days in advance of such record date.

                                      C-1

 
     3. In the event of a stock split, conversion, recapitalization,
reorganization or any other similar transaction resulting in the cancellation of
all or any part of the Capital Securities outstanding, the Issuer or the
Transfer Agent and Registrar shall send DTC a notice of such event at least 5
business days prior to the effective date of such event.

     4. In the event of distribution on, or an offering or issuance of rights
with respect to, the Capital Securities outstanding, the Issuer or the Transfer
Agent and Registrar shall send DTC a notice specifying: (a) the amount of and
conditions, if any, applicable to the payment of any such distribution or any
such offering or issuance of rights; (b) any applicable expiration or deadline
date, or any date by which any action on the part of the holders of Capital
Securities is required; and (c) the date any required notice is to be mailed by
or on behalf of the Issuer to holders of Capital Securities or published by or
on behalf of the Issuer (whether by mail or publication, the "Publication
Date"). Such notice shall be sent to DTC by a secure means (e.g., legible
telecopy, registered or certified mail, overnight delivery) in a timely manner
designed to assure that such notice is in DTC's possession no later than the
close of business on the business day before the Publication Date. The Issuer or
the Transfer Agent and Registrar will forward such notice either in a separate
secure transmission for each CUSIP number or in a secure transmission of
multiple CUSIP numbers (if applicable) that includes a manifest or list of each
CUSIP number submitted in that transmission. (The party sending such notice
shall have a method to verify subsequently the use of such means and the
timeliness of such notice.) The Publication Date shall be not less than 30
calendar days nor more than 60 calendar days prior to the payment of any such
distribution or any such offering or issuance of rights with respect to the
Capital Securities. After establishing the amount of payment to be made on the
Capital Securities, the Issuer or the Transfer Agent and Registrar will notify
DTC's Dividend Department of such payment 5 business days prior to payment date.
Notices to DTC's Dividend Department by telecopy shall be sent to (212) 709-
1723. Such notices by mail or by any other means shall be sent to:

          Manager, Announcements
          Dividend Department

          7 Hanover Square, 23rd Floor
          New York, New York 10004-2695

     The Issuer or the Transfer Agent and Registrar shall confirm DTC's receipt
of such telecopy by telephoning the Dividend Department at (212) 709-1270.

     5. In the event of a redemption by the Issuer of the Capital Securities,
notice specifying the terms of the redemption and the Publication Date of such
notice shall be sent by the Issuer or the Transfer Agent and Registrar to DTC
not less than 30 calendar days prior to such event by a secure means in the
manner set forth in paragraph 4. Such redemption notice shall be sent to DTC's
Call Notification Department at (516) 227-4164 or (516) 227-4190, and receipt of
such notice shall be confirmed by telephoning (516) 227-4070. Notice by mail or
by any other means shall be sent to:

          Call Notification Department
          The Depository Trust Company
          711 Stewart Avenue
          Garden City, New York 11530-4719

     6. In the event of any invitation to tender the Capital Securities, notice
specifying the terms of the tender and the Publication Date of such notice shall
be sent by the Issuer or the Transfer Agent and Registrar to DTC by a secure
means and in a timely manner as described in paragraph 4. Notices to DTC
pursuant to this paragraph and notices of other corporate actions (including
mandatory tenders, exchanges and capital changes) shall be sent, unless
notification to another department is expressly provided for herein, by telecopy
to DTC's Reorganization Department at (212) 709-1093 or (212) 709-1094 and
receipt of such notice shall be confirmed by telephoning (212) 709-6884, or by
mail or any other means to:

          Manager, Reorganization Department
          Reorganization Window

                                      C-2

 
          The Depository Trust Company
          7 Hanover Square, 23rd Floor
          New York, New York 10004-2695

     7. All notices and payment advices sent to DTC shall contain the CUSIP
number or numbers of the Capital Securities and the accompanying designation of
the Capital Securities, which, as of the date of this letter, is "FBS Capital I
8.09% Capital Securities."

     8. Distribution payments or other cash payments with respect to the Capital
Securities evidenced by the Global Certificate shall be received by Cede & Co.,
as nominee of DTC, or its registered assigns in same day funds on each payment
date (or in accordance with existing arrangements between the Issuer or the
Transfer Agent and Registrar and DTC). Such payments shall be made payable to
the order of Cede & Co., and shall be addressed as follows:

          Redemption Department
          The Depository Trust Company
          7 Hanover Square, 23rd Floor
          New York, New York 10004-2695

     9. DTC may by prior written notice direct the Issuer and the Transfer Agent
and Registrar to use any other telecopy number or address of DTC as the number
or address to which notices or payments may be sent.

     10. In the event of a conversion, redemption, or any other similar
transaction (e.g., tender made and accepted in response to the Issuer's or the
Transfer Agent and Registrar's invitation) necessitating a reduction in the
aggregate number of Capital Securities outstanding evidenced by Global
Certificates, DTC, in its discretion: (a) may request the Issuer or the Transfer
Agent and Registrar to issue and countersign a new Global Certificate; or (b)
may make an appropriate notation on the Global Certificate indicating the date
and amount of such reduction.

     11. DTC may discontinue its services as a securities depositary with
respect to the Capital Securities at any time by giving reasonable written
notice to the Issuer and the Transfer Agent and Registrar (at which time DTC
will confirm with the Issuer or the Transfer Agent and Registrar the aggregate
number of Capital Securities deposited with it) and discharging its
responsibilities with respect thereto under applicable law. Under such
circumstances, the Issuer may determine to make alternative arrangements for
book-entry settlement for the Capital Securities, make available one or more
separate global certificates evidencing Capital Securities to any Participant
having Capital Securities credited to its DTC account, or issue definitive
Capital Securities to the beneficial holders thereof, and in any such case, DTC
agrees to cooperate fully with the Issuer and the Transfer Agent and Registrar,
and to return the Global Certificate, duly endorsed for transfer as directed by
the Issuer or the Transfer Agent and Registrar, together with any other
documents of transfer reasonably requested by the Issuer or the Transfer Agent
and Registrar.

     12. In the event that the Issuer determines that beneficial owners of
Capital Securities shall be able to obtain definitive Capital Securities, the
Issuer or the Transfer Agent and Registrar shall notify DTC of the availability
of certificates. In such event, the Issuer or the Transfer Agent and Registrar
shall issue, transfer and exchange certificates in appropriate amounts, as
required by DTC and others, and DTC agrees to cooperate fully with the Issuer
and the Transfer Agent and Registrar and to return the Global Certificate, duly
endorsed for transfer as directed by the Issuer or the Transfer Agent and
Registrar, together with any other documents of transfer reasonably requested by
the Issuer or the Transfer Agent and Registrar.

     13. This letter may be executed in any number of counterparts, each of
which when so executed shall be deemed to be an original, but all such
counterparts shall together constitute but one and the same instrument.

                                      C-3

 
     Nothing herein shall be deemed to require the Transfer Agent and Registrar
to advance funds on behalf of FBS Capital I.

     AGREEMENT dated as of November 26, 1996, between First Bank System, Inc., a
Delaware corporation ("FBS"), and FBS Capital I, a Delaware business trust (the
"Trust").

     WHEREAS, the Trust intends to issue its 8.09% Common Securities (the
"Common Securities") to and receive Debentures from FBS and to issue and sell
8.09% Capital Securities (the "Private Capital Securities") with such powers,
preferences and special rights and restrictions as are set forth in the Amended
and Restated Trust Agreement of the Trust dated as of November 26, 1996 as the
same may be amended from time to time (the "Trust Agreement");

     WHEREAS, FBS will issue the Debentures;

     WHEREAS, the Trust may issues a new series of 8.09% capital securities
(the "Exchange Capital Securities" and, together with the "Private Capital
Securities," the "Capital Securities") in connection with an exchange offer (the
"Exchange Offer") registered under the Securities Act or 1933, as amended;

     NOW, THEREFORE, in consideration of the purchase by the Trust of the
Debentures, which purchase FBS acknowledges will be made in reliance upon the
execution and delivery of this Agreement, FBS and Trust hereby agree as follows:


                                   ARTICLE I

     SECTION 1.1. Guarantee by FBS.

     Subject to the terms and conditions hereof, FBS hereby irrevocably and
unconditionally guarantees to each person or entity to whom the Trust is now or
hereafter becomes indebted or liable (the "Beneficiaries") the full payment,
when and as due, of any and all Obligations (as hereinafter defined) to such
Beneficiaries. As used herein, "Obligations" means any costs, expenses or
liabilities of the Trust, other than obligations of the Trust to pay to holders
of any Capital Securities or other similar interests in the Trust the amounts
due such holders pursuant to the terms of the Capital Securities or such other
similar interests, as the case may be. This Agreement is intended to be for the
benefit of, and to be enforceable by, all such Beneficiaries, whether or not
such Beneficiaries have received notice hereof.

     SECTION 1.2. Term of Agreement.

     This Agreement shall terminate and be of no further force and effect
upon the later of (a) the date on which full payment has been made of all
amounts payable to all holders of all the Capital Securities (whether upon
redemption, liquidation, exchange or otherwise) and (b) the date on which there
are no Beneficiaries remaining; provided, however, that this Agreement shall
continue to be effective or shall be reinstated, as the case may be, if at any
time any holder of Capital Securities or any Beneficiary must restore payment of
any sums paid under the Capital Securities, under any Obligation, under the
Guarantee Agreement dated the date hereof by FBS and Wilmington Trust Company,
as guarantee, under the New Guarantee Agreement entered into to replace such
Guarantee Agreement by such parties in connection with the Exchange Offer,
trustee or under this Agreement for any reason whatsoever. This Agreement is
continuing, irrevocable, unconditional and absolute.

     SECTION 1.3. Waiver of Notice.

     FBS hereby waives notice of acceptance of this Agreement and of any
Obligation to which it applies or may apply, and FBS hereby waives presentment,
demand for payment, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands.

                                      E-1

 
     SECTION 1.4. No Impairment.

     The obligations, covenants, agreements and duties of FBS under this
Agreement shall in no way be affected or impaired by reason of the happening
from time to time of any of the following:

     (a) the extension of time for the payment by the Trust of all or any
portion of the Obligations or for the performance of any other obligation under,
arising out of, or in connection with, the obligations;

     (b) any failure, omission, delay or lack of diligence on the part of the
Beneficiaries to enforce, assert or exercise any right, privilege, power or
remedy conferred on the Beneficiaries with respect to the Obligations or any
action on the part of the Trust granting indulgence or extension of any kind; or

     (c) the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,
or other similar proceedings affecting, the Trust or any of the assets of the
Trust.

There shall be no obligation of the Beneficiaries to give notice to, or obtain
the consent of, FBS with respect to the happening of any of the foregoing.

     SECTION 1.5. Enforcement.

     A Beneficiary may enforce this Agreement directly against FBS and FBS
waives any right or remedy to require that any action be brought against the
Trust or any other person or entity before proceeding against FBS.

     SECTION 1.6. Subrogation.

     FBS shall be subrogated to all (if any) rights of the Trust in respect of
any amounts paid to the Beneficiaries by FBS under this Agreement; provided,
however, that FBS shall not (except to the extent required by mandatory
provisions of law) be entitled to enforce or exercise any rights which it may
acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Agreement, if, at the
time of any such payment, any amounts are due and unpaid under this Agreement.


                                   ARTICLE II

     SECTION 2.1. Binding Effect.

     All guarantees and agreements contained in this Agreement shall bind the
successors, assigns, receivers, trustees and representatives of FBS and shall
inure to the benefit of the Beneficiaries.

     SECTION 2.2. Amendment.

     So long as there remains any Beneficiary or any Capital Securities of any
series are outstanding, this Agreement shall not be modified or amended in any
manner adverse to such Beneficiary or to the holders of the Capital Securities.

     SECTION 2.3. Notices.

     Any notice, request or other communication required or permitted to be
given hereunder shall be given in writing by delivering the same against receipt
therefor by facsimile transmission (confirmed by mail), telex or by registered

Securities Act of 1933, as amended (the "Securities Act"). In addition, if we
are buying for one or more accounts for which we are acting as fiduciary or
agent and we are not a bank (as defined in Section 3(a)(2) of the Securities Act
or a savings and loan association or other institution (as defined in Section
3(a)(5)(A) of the Securities Act), each such account is an institutional
investor and an accredited investor on a like basis.

     2.   We are acquiring the Capital Securities for our own account or for an
account for which we are acting as fiduciary or agent in a minimum amount of not
less than $100,000 Liquidation Amount for each such account. We acknowledge and
agree that the Capital Securities purchased by us will be issued in certificated
form bearing a legend to the effect of paragraph 5 and may not be exchanged for
Capital Securities in book-entry form. We further acknowledge and agree that the
provisions of this paragraph 2 and those of paragraph 3 below will apply to each
Capital Security purchased by us until such time s such Capital Security is
transferred in compliance with the provisions of paragraph 3.

     3.   We understand that the Capital Securities have not been registered
under the Securities Act and we agree that the Capital Securities purchased by
us may be reoffered, resold, pledged or otherwise transferred only:

          (i)  (a) to a person who the seller reasonably believes is a
     "qualified institutional buyer" within the meaning of Rule 144A under the
     Securities Act, purchasing for its own account or the account of a
     qualified institutional buyer in a transaction meeting the requirement of
     Rule 144A;

               (b) in an offshore transaction complying with Rule 903 or 904 of
     Regulation S under the Securities Act;

               (c) pursuant to an exemption from registration under the
     Securities Act provided by Rule 144 thereunder (if available); or

               (d) pursuant to an effective registration statement under the
     Securities Act; and

          (ii) in accordance with all applicable securities laws of the
     United States and other jurisdictions.

                                      F-1

matters that we are capable of evaluating the merits and risk of an  investment
in the Capital Securities, we, and any accounts for which we are acting are able
to bear the economic risk of purchasing such Capital Securities and we have
received a copy of the Offering Circular.

     5.   We acknowledge that the Capital Securities will bear a legend to
the following effect unless the Property Trustee determines otherwise
consistently with applicable law:

          "THE SECURITIES EVIDENCED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
