     to be executed and filed by the Issuer Trust or on behalf of the Issuer
     Trust, as the Depositor deems necessary or advisable in order to comply
     with the applicable laws of any such States in connection with the sale of
     the Capital Securities;

          (iii) the negotiation of the terms of, and the execution and delivery
     of, the Purchase Agreement providing for the sale of the Capital
     Securities; and

          (iv) the taking of any other actions necessary or desirable to carry
     out any of the foregoing activities.

     (d) Notwithstanding anything herein to the contrary, the Administrators and
the Issuer Trustees are authorized and directed to conduct the affairs of the
Issuer Trust and to operate the Issuer Trust so that the Issuer Trust will not
be deemed to be an "investment company" required to be registered under the
Investment Company Act, and will not be taxable as a corporation or classified
as other than a grantor trust for United States Federal income tax purposes and
so that the Debentures will be treated as indebtedness of the Depositor for
United States Federal income tax purposes. In this connection, each
Administrator, the Property Trustee and the Holders of at least a Majority in
Liquidation Amount of the Common Securities are authorized to take any action,
not inconsistent with applicable law, the Certificate of Trust or this Trust
Agreement, that such Administrator, the Property Trustee or Holders of Common
Securities determine in their discretion to be necessary or desirable for such
purposes, as long as such action does not adversely affect in any material
respect the interests of the Holders of the Outstanding Capital Securities. In
no event shall the Administrators or the Issuer Trustees be liable to the Issuer
Trust or the Holders for any failure to comply with this section that results
from a change in law or regulation or in the interpretation thereof.

     Section 2.8.  Assets of Trust.

     The assets of the Issuer Trust shall consist of the Trust Property.

                                       17

 
     Section 2.9.  Title to Trust Property.

     Legal title to all Trust Property shall be vested at all times in the
Property Trustee (in its capacity as such) and shall be held and administered by
the Property Trustee in trust for the benefit of the Issuer Trust and the
Holders in accordance with this Trust Agreement.


                                  ARTICLE III.

                                Payment Account

     Section 3.1.  Payment Account.

     (a) On or prior to the Closing Date, the Property Trustee shall establish
the Payment Account. The Property Trustee and its agents shall have exclusive
control and sole right of withdrawal with respect to the Payment Account for the
purpose of making deposits in and withdrawals from the Payment Account in
accordance with this Trust Agreement. All monies and other property deposited or
held from time to time in the Payment Account shall be held by the Property
Trustee in the Payment Account for the exclusive benefit of the Holders and for
distribution as herein provided, including (and subject to) any priority of
payments provided for herein.

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


                                  ARTICLE IV.

                           Distributions; Redemption

     Section 4.1.  Distributions.

     (a) The Trust Securities represent undivided beneficial interests in the
Trust Property, and Distributions (including of Additional Amounts) will be made
on the Trust Securities at the rate and on the dates that payments of interest
(including of Additional Interest, as defined in the Indenture) are made on the
Debentures. Accordingly:

          (i) Distributions on the Issuer Trust Securities shall be cumulative,
     and will accumulate whether or not there are funds of the Trust available
     for the payment of Distributions. Distributions shall accumulate from
     December 20, 1996, and, except in the event (and to the extent) that the
     Depositor exercises its right to defer the payment

                                       18

 
     of interest on the Debentures pursuant to the Indenture, shall be payable
     semi-annually in arrears on June 30 and December 30 of each year,
     commencing on June 30, 1997. If any date on which a Distribution is
     otherwise payable on the Trust Securities is not a Business Day, then the
     payment of such Distribution shall be made on the next succeeding day that
     is a Business Day (and without any interest or other payment in respect of
     any such delay), with the same force and effect as if made on the date on
     which such payment was originally payable (each date on which distributions
     are payable in accordance with this Section 4.1(a), a "Distribution Date").

          (ii) The Trust Securities shall be entitled to Distributions payable
     at a rate of 7.94% per annum of the Liquidation Amount of the Trust
     Securities. The amount of Distributions payable for any period less than a
     full Distribution period shall be computed on the basis of a 360-day year
     of twelve 30-day months and the actual number of days elapsed in a partial
     month in a period. Distributions payable for each full Distribution period
     will be computed by dividing the rate per annum by two. The amount of
     Distributions payable for any period shall include any Additional Amounts
     in respect of such period.

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

     (b) Distributions on the Trust Securities with respect to a Distribution
Date shall be payable to the Holders thereof as they appear on the Securities
Register for the Trust Securities at the close of business on the relevant
record date, which shall be at the close of business on the fifteenth day
(whether or not a Business Day) next preceding the relevant Distribution Date.

     Section 4.2.  Redemption.

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

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

          (i) the Redemption Date;

          (ii) the Redemption Price or if the Redemption Price cannot be
     calculated prior to the time the notice is required to be sent, the
     estimate of the Redemption Price

                                       19

 
     together with a statement that it is an estimate and that the actual
     Redemption Price will be calculated on the third Business Day prior to the
     Redemption Date (and if an estimate is provided, a further notice shall be
     sent of the actual Redemption Price on the date that such Redemption Price
     is calculated);

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

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

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

          (vi) the place or places where the Trust Securities are to be
     surrendered for the payment of the Redemption Price.

     The Trust in issuing the Trust Securities may use "CUSIP" or "private
placement" numbers (if then generally in use), and, if so, the Property Trustee
shall indicate the "CUSIP" or "private placement" numbers of the Trust
Securities in notices of redemption and related materials as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Trust Securities
or as contained in any notice of redemption and related materials.

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

     (d) If the Property Trustee gives a notice of redemption in respect of any
Capital Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 4.2(c), the Property Trustee will, with respect to
Book-Entry Capital Securities, irrevocably deposit with the Clearing Agency for
such Book-Entry Capital Securities, to the extent available therefor, funds
sufficient to pay the applicable Redemption Price and will give such Clearing
Agency irrevocable instructions and authority to pay the Redemption Price to the
Holders of the Capital Securities. With respect to Capital Securities that are
not Book-Entry Capital Securities, the Property Trustee, subject to Section
4.2(c), will irrevocably deposit with the Paying Agent, to the extent available
therefor, funds sufficient to pay the applicable Redemption Price and will give
the Paying Agent irrevocable instructions and authority to pay the Redemption
Price to the Holders of the Capital Securities upon surrender of their Capital

                                       20

 
Securities Certificates. Notwithstanding the foregoing, Distributions payable on
or prior to the Redemption Date for any Trust Securities called for redemption
shall be payable to the Holders of such Trust Securities as they appear on the
Securities Register for the Trust Securities on the relevant record dates for
the related Distribution Dates. If notice of redemption shall have been given
and funds deposited as required, then upon the date of such deposit, all rights
of Holders holding Trust Securities so called for redemption will cease, except
the right of such Holders to receive the Redemption Price and any Distribution
payable in respect of the Trust Securities on or prior to the Redemption Date,
but without interest, and such Securities will cease to be outstanding. In the
event that any date on which any Redemption Price is payable is not a Business
Day, then payment of the Redemption Price payable on such date will be made on
the next succeeding day that is a Business Day (without any interest or other
payment in respect of any such delay), 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 Redemption Price in respect of
any Trust Securities called for redemption is improperly withheld or refused and
not paid either by the Issuer Trust or by the Depositor pursuant to the
Guarantee Agreement, Distributions on such Trust Securities will continue to
accumulate, as set forth in Section 4.1, from the Redemption Date originally
established by the Issuer Trust for such Trust Securities to the date such
Redemption Price is actually paid, in which case the actual payment date will be
the date fixed for redemption for purposes of calculating the Redemption Price.

     (e) Subject to Section 4.3(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated pro
rata to the Common Securities and the Capital Securities based upon the relative
Liquidation Amounts of such classes. The particular Capital Securities to be
redeemed shall be selected on a pro rata basis based upon their respective
Liquidation Amounts not more than 60 days prior to the Redemption Date by the
Property Trustee from the Outstanding Capital Securities not previously called
for redemption, provided that so long as the Capital Securities are in book-
entry-only form, such selection shall be made in accordance with the customary
procedures for the Clearing Agency for the Capital Securities, and provided
further that, after giving effect to such redemption, no Holder shall hold
Capital Securities with an aggregate Liquidation Amount of less than $100,000.
The Property Trustee shall promptly notify the Securities Registrar in writing
of the Capital Securities selected for redemption and, in the case of any
Capital Securities selected for partial redemption, the Liquidation Amount
thereof to be redeemed. For all purposes of this Trust Agreement, unless the
context otherwise requires, all provisions relating to the redemption of Capital
Securities shall relate, in the case of any Capital Securities redeemed or to be
redeemed only in part, to the portion of the aggregate Liquidation Amount of
Capital Securities that has been or is to be redeemed.

     Section 4.3.  Subordination of Common Securities.

     (a) Payment of Distributions (including any Additional Amounts) on, the
Redemption Price of, and the Liquidation Distribution in respect of the Trust
Securities, as applicable, shall

                                       21

 
be made, subject to Section 4.2(e), pro rata among the Common Securities and the
Capital Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date, Redemption Date or
Liquidation Date any Event of Default resulting from a Debenture Event of
Default specified in Section 5.1(1) or 5.1(2) of the Indenture shall have
occurred and be continuing, no payment of any Distribution (including any
Additional Amounts) on, Redemption Price of, or Liquidation Distribution in
respect of any Common Security, and no other payment on account of the
redemption, liquidation or other acquisition of Common Securities, shall be made
unless payment in full in cash of all accumulated and unpaid Distributions
(including any Additional Amounts) on all Outstanding Capital Securities for all
Distribution periods terminating on or prior thereto, or in the case of payment
of the Redemption Price the full amount of such Redemption Price on all
Outstanding Capital Securities then called for redemption, or in the case of
payment of the Liquidation Distribution the full amount of such Liquidation
Distribution on all Outstanding Capital Securities, shall have been made or
provided for, and all funds immediately available to the Property Trustee shall
first be applied to the payment in full in cash of all Distributions (including
any Additional Amounts) on, or the Redemption Price of, the Capital Securities
then due and payable.

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

     Section 4.4.  Payment Procedures.

     Payments of Distributions (including any Additional Amounts) in respect of
the Capital Securities shall 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. Payments in
respect of the Common Securities shall be made in such manner as shall be
mutually agreed between the Property Trustee and the Holders of the Common
Securities.

     Section 4.5.  Tax Returns and Reports.

     The Administrators 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
Issuer Trust. In this regard, the Administrators shall (a) prepare and file (or
cause to be prepared and filed) all Internal Revenue Service forms required to
be filed in respect of the Issuer Trust in each taxable year of the Issuer
Trust, and

                                       22

 
(b) prepare and furnish (or cause to be prepared and furnished) to each Holder
all Internal Revenue Service forms required to be provided by the Issuer Trust.
The Administrators shall provide the Depositor and the Property Trustee with a
copy of all such returns and reports promptly after such filing or furnishing.
The Issuer Trustees shall comply with United States Federal withholding and
backup withholding tax laws and information reporting requirements with respect
to any payments to Holders under the Trust Securities.

     Section 4.6.  Payment of Taxes, Duties, Etc. of the Issuer 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 Issuer Trust by the United
States or any other taxing authority.

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

     Any amount payable hereunder to any Holder of Capital Securities (or any
Owner with respect thereto) shall be reduced by the amount of any corresponding
payment such Holder (or Owner) has directly received pursuant to Section 5.8 of
the Indenture or Section 5.13 of this Trust Agreement.

     Section 4.8.  Liability of the Holder of Common Securities.

     Any Holder of the Common Securities shall be liable for the debts and
obligations of the Issuer Trust in the manner and to the extent set forth with
respect to the Common Securityholder (as defined in the Expense Agreement) and
agrees that it shall be subject to all liabilities to which the Common
Securityholder may be subject, and shall make all payments that the Common
Securityholder is required to make, under the terms of the Expense Agreement.

integral multiples thereof. The Trust Securities Certificates shall be executed
on behalf of the Issuer Trust by manual signature of at least one Administrator.
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 Issuer 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 Holder, and shall be entitled to the
rights and subject to the obligations of a Holder hereunder, upon due
registration of such Trust Securities Certificate in such transferee's name
pursuant to Section 5.5.

     (b) Upon their original issuance, Capital Securities Certificates
representing Rule 144A Capital Securities shall be issued in the form of one or
more Book-Entry Capital Securities Certificates registered in the name of DTC,
as Clearing Agency, or its nominee and deposited with DTC or a custodian for DTC
for credit by DTC to the respective accounts of the Owners thereof (or such
other accounts as they may direct).

     (c) Upon their original issuance, Capital Securities Certificates
representing Other Capital Securities shall not be issued in the form of a Book-
Entry Capital Securities Certificate or in any other form intended to facilitate
book-entry trading in beneficial interests in such Capital Securities.

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

     Section 5.3.  Execution and Delivery of Trust Securities Certificates.

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

                                       24

 
     Section 5.4.  Book-Entry Capital Securities.

     (a) Each Book-Entry Capital Securities Certificate issued under this
Agreement shall be registered in the name of the Clearing Agency or a nominee
thereof and delivered to such Clearing Agency or a nominee thereof or custodian
therefor, and each such Book-Entry Capital Securities Certificate shall
constitute a single Capital Securities Certificate for all purposes of this
Agreement.

     (b) Notwithstanding any other provision in this Trust Agreement, no Book-
Entry Capital Securities Certificate may be exchanged in whole or in part for
Capital Securities Certificates registered, and no transfer of a Book-Entry
Capital Securities Certificate in whole or in part may be registered, in the
name of any Person other than the Clearing Agency for such Book-Entry Capital
Securities Certificates or a nominee thereof unless (a) the Clearing Agency
advises the Property Trustee in writing that the Clearing Agency is no longer
willing or able to properly discharge its responsibilities with respect to the
Book-Entry Capital Securities Certificates, and the Property Trustee is unable
to locate a qualified successor, (b) the Issuer Trust at its option advises the
Depositary in writing that it elects to terminate the book-entry system through
the Clearing Agency, (c) a Debenture Event of Default has occurred and is
continuing, or (d) in the case of a transfer of a beneficial interest in such
Capital Security to a Person that is not a "qualified institutional buyer"
within the meaning of Rule 144A under the Securities Act, upon reasonable prior
notice of such transfer by the Depositary or its authorized representative to
the Securities Registrar and delivery to the Securities Registrar of a
Restricted Securities Certificate duly authorized by the Depositary or its
authorized representative; provided, however, that no Definitive Capital
Securities Certificate shall be issued in an amount representing less than 100
Capital Securities. Upon the occurrence of any event specified in clause (a),
(b) or (c) above, the Administrators shall notify the Clearing Agency and
instruct the Clearing Agency to notify all Owners of Book-Entry Capital
Securities, the Delaware Trustee and the Administrators of the occurrence of
such event and of the availability of the Definitive Capital Securities
Certificates to Owners of such class or classes, as applicable, requesting the
same; provided, however, that no Definitive Capital Securities Certificate shall
be issued in an amount representing less than 100 Capital Securities.

     (c) If any Book-Entry Capital Securities Certificate is to be exchanged for
other Capital Securities Certificates or cancelled in part, or if any other
Capital Securities Certificate is to be exchanged in whole or in part for Book-
Entry Capital Securities represented by a Book-Entry Capital Securities
Certificate, then either (i) such Book-Entry Capital Securities Certificate
shall be so surrendered for exchange or cancellation as provided in this Article
Five or (ii) the aggregate Liquidation Amount represented by such Book-Entry
Capital Securities Certificate shall be reduced, subject to Section 5.2, or
increased by an amount equal to the Liquidation Amount represented by that
portion of the Book-Entry Capital Securities Certificate to be so exchanged or
cancelled, or equal to the Liquidation Amount represented by such other Capital
Securities Certificates to be so exchanged for Book-Entry Capital Securities
represented thereby, as the case may be, by means of an appropriate adjustment
made on the records of the Securities 

                                       25

 
Registrar, whereupon the Property Trustee, in accordance with the Applicable
Procedures, shall instruct the Clearing Agency or its authorized representative
to make a corresponding adjustment to its records. Upon surrender to the
Administrators or the Securities Registrar of the Book-Entry Capital Securities
Certificate or Certificates by the Clearing Agency, accompanied by registration
instructions, the Administrators, or any one of them, shall execute the
Definitive Capital Securities Certificates in accordance with the instructions
of the Clearing Agency; provided, however, that no Definitive Capital Securities
Certificate shall be issued in an amount representing less than 100 Capital
Securities. None of the Securities Registrar, the Issuer Trustees or the
Administrators shall be liable for any delay in delivery of such instructions
and may conclusively rely on, and shall be protected in relying on, such
instructions. Upon the issuance of Definitive Capital Securities Certificates,
the Issuer Trustees and Administrators shall recognize the Holders of the
Definitive Capital Securities Certificates as Holders. 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 Administrators,
as evidenced by the execution thereof by the Administrators or any one of them.

     (d) Every Capital Securities Certificate executed and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Book-Entry
Capital Securities Certificate or any portion thereof, whether pursuant to this
Article V or Article IV or otherwise, shall be executed and delivered in the
form of, and shall be, a Book-Entry Capital Securities Certificate, unless such
Capital Securities Certificate is registered in the name of a Person other than
the Clearing Agency for such Book-Entry Capital Securities Certificate or a
nominee thereof.

     (e) The Clearing Agency or its nominee, as registered owner of a Book-Entry
Capital Securities Certificate, shall be the Holder of such Book-Entry Capital
Securities Certificate for all purposes under this Agreement and the Book-Entry
Capital Securities Certificate, and Owners with respect to a Book-Entry Capital
Securities Certificate shall hold such interests pursuant to the Applicable
Procedures. The Securities Registrar, the Administrators and the Issuer 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
Book-Entry Capital Securities represented thereby and the giving of instructions
or directions by Owners of Book-Entry Capital Securities represented thereby) as
the sole Holder of the Book-Entry Capital Securities represented thereby and
shall have no obligations to the Owners thereof. None of the Property Trustee,
the Administrators nor the Securities Registrar shall have any liability in
respect of any transfers effected by the Clearing Agency.

     The rights of the Owners of the Book-Entry Capital Securities shall be
exercised only through the Clearing Agency and shall be limited to those
established by law, the Applicable Procedures and agreements between such Owners
and the Clearing Agency and/or the Clearing Agency Participants. Pursuant to the
Certificate Depository Agreement, unless and until Definitive Capital Securities
Certificates are issued pursuant to Section 5.4(b), the initial Clearing Agency
will make book-entry transfers among the Clearing Agency Participants and

                                       26

 
receive and transmit payments on the Capital Securities to such Clearing Agency
Participants, and none of the Depositor, the Administrators or the Issuer
Trustees shall have any responsibility or obligation with respect thereto.

     Section 5.5.  Registration of Transfer and Exchange of Capital Securities
Certificates; Restricted Capital Securities Legends.

     (a) The Property Trustee shall keep or cause to be kept, at the office or
agency maintained pursuant to Section 5.9, a register or registers for the
purpose of registering Trust Securities Certificates and transfers and exchanges
of Trust Securities Certificates (the "Securities Register") in which the
registrar and transfer agent with respect to the Trust Securities (the
"Securities Registrar"), subject to such reasonable regulations as it may
prescribe, shall provide for the registration of Capital Securities Certificates
and Common Securities Certificates (subject to Section 5.11 in the case of the
Common Securities Certificates) and registration of transfers and exchanges of
Capital Securities Certificates as herein provided. The Person acting as the
Property Trustee shall at all times also be the Securities Registrar.

     Upon surrender for registration of transfer of any Capital Securities
Certificate at the office or agency maintained pursuant to Section 5.9, the
Administrators or any one of them shall execute and deliver to the Property
Trustee, and the Property Trustee shall 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 Administrator; provided that no Holder may transfer any
Capital Security if giving effect to such transfer would cause any Holder to
hold less than $100,000 aggregate Liquidation Amount of Capital Securities. Any
purported transfer prohibited by the preceding proviso shall be null and void
and of no force or effect and the purported transferee of the affected Capital
Securities shall be deemed to have no interest whatsoever in such Capital
Securities.

     The Securities Registrar shall not be required, (i) to issue, register the
transfer of or exchange any Capital Security during a period beginning at the
opening of business 15 days before the day of selection for redemption of such
Capital Securities pursuant to Article IV and ending at the close of business on
the day of mailing of the notice of redemption, or (ii) to register the transfer
of or exchange any Capital Security so selected for redemption in whole or in
part, except, in the case of any such Capital Security to be redeemed in part,
any portion thereof not to be redeemed.

     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 the Securities Registrar duly
executed by the Holder or its attorney duly authorized in writing. Each Capital
Securities Certificate surrendered for registration of transfer or exchange
shall be cancelled and subsequently disposed of by the Property Trustee in
accordance with such Person's customary practice.

                                       27

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

     (b) Notwithstanding any other provision of this Agreement, transfers and
exchanges of Capital Securities Certificates and beneficial interests in a Book-
Entry Capital Securities Certificate of the kinds specified in this Section
5.5(b) shall be made only in accordance with this Section 5.5(b).

          (i)   Non-Book-Entry Capital Securities Certificate to Book-Entry
                -----------------------------------------------------------
     Capital Securities Certificate. If the Holder of a Capital Securities
     ------------------------------                                       
     Certificate (other than a Book-Entry Capital Securities Certificate) wishes
     at any time to transfer all or any portion of such Capital Securities
     Certificate to a Person who wishes to take delivery thereof in the form of
     a beneficial interest in a Book-Entry Capital Securities Certificate, such
     transfer may be effected only in accordance with the provisions of this
     Clause (b)(i) and subject to the Applicable Procedures. Upon receipt by the
     Securities Registrar of (A) such Capital Securities Certificate as provided
     in Section 5.5(a) and instructions satisfactory to the Securities Registrar
     directing that a beneficial interest in the Book-Entry Capital Securities
     Certificate of a specified number of Capital Securities not greater than
     the number of Capital Securities represented by such Capital Securities
     Certificate be credited to a specified Clearing Agency Participant's
     account and (B) a Restricted Securities Certificate duly executed by such
     Holder or his attorney duly authorized in writing, then the Securities
     Registrar shall cancel such Capital Securities Certificate (and issue a new
     Capital Securities Certificate in respect of any untransferred portion
     thereof) as provided in Section 5.5(a) and increase the aggregate
     Liquidation Amount of the Book-Entry Capital Securities Certificate by the
     Liquidation Amount represented by such Capital Securities so transferred as
     provided in Section 5.4(c).

          (ii)  Non-Book-Entry Capital Securities Certificate to Non-Book-Entry
                ---------------------------------------------------------------
     Capital Securities Certificate. A Capital Securities Certificate that is
     ------------------------------                                          
     not a Book-Entry Capital Securities Certificate may be transferred, in
     whole or in part, to a Person who takes delivery in the form of another
     Capital Securities Certificate that is not a Book-Entry Capital Securities
     Certificate as provided in Section 5.5(a), provided that if the Capital
                                                --------                    
     Securities Certificate evidences Restricted Securities Certificate, then
     the Securities Registrar shall have received a Restricted Securities
     Certificate duly executed by the transferor Holder or his attorney duly
     authorized in writing in which case the transferee Holder shall take
     delivery in the form of a Restricted Capital Securities Certificate
     (subject to Section 5.5(c)).

          (iii) Exchanges between Book-Entry Capital Securities Certificate and
                ---------------------------------------------------------------
     Non-Book- Entry Capital Securities Certificate. A beneficial interest in a
     ----------------------------------------------                            
     Book-Entry Capital Securities Certificate may be exchanged for a Capital
     Securities Certificate that is not a 

                                       28

 
     Book-Entry Capital Securities Certificate as provided in Section 5.4,
     provided that such interest shall be exchanged for a Restricted Capital
     --------
     Securities Certificate (subject in each case to Section 5.5(c)).

          (iv)  Certain Initial Transfers of Non-Book-Entry Capital Securities
                --------------------------------------------------------------
     Certificates. In the case of Capital Securities Certificates initially
     ------------                                                          
     issued other than in global form, an initial transfer or exchange of such
     Capital Securities Certificates that does not involve any change in
     beneficial ownership may be made to an Institutional Accredited Investor or
     Investors as if such transfer or exchange were not an initial transfer or
     exchange, provided that written certification shall be provided by the
     transferor and transferee of such Securities to the Securities Registrar
     that such transfer or exchange does not involve a change in beneficial
     ownership.

          (v)    Limitations Relating to Size of Blocks. Notwithstanding any
                 --------------------------------------
     other provision of this Trust Agreement, Capital Securities may only be
     transferred or exchanged in blocks having a Liquidation Amount of not less
     than $100,000. In addition, Capital Securities may not be transferred or
     exchanged by any Holder if, following such transfer or exchange, such
     Holder would have Capital Securities with an aggregate Liquidation Amount
     of less than $100,000. Any transfer, exchange or other disposition of
     Capital Securities in contravention of this Section 5.5(b)(v) shall be
     deemed to be void and of no legal effect whatsoever, any such transferee
     shall be deemed not to be the Holder or Owner of such Capital Security 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.

          (c)   Restricted Capital Securities Legend. Certificates evidencing
                ------------------------------------
Rule 144A Capital Securities, Other Capital Securities and their respective
Successor Capital Securities shall bear a Restricted Capital Securities Legend,
subject to the following:

          (i) subject to the following Clauses of this Section 5.5(c), a Capital
     Securities Certificate or any portion thereof that is exchanged, upon
     transfer or otherwise, for a Book-Entry Capital Securities Certificate or
     any portion thereof shall bear a Restricted Capital Securities Legend;

          (ii) subject to the following Clauses of this Section 5.5(c), a new
     Capital Securities Certificate that is not a Book-Entry Capital Securities
     Certificate and is issued in exchange for another Capital Securities
     Certificate (including a Book-Entry Capital Securities Certificate) or any
     portion thereof, upon transfer or otherwise, shall, bear a Restricted
     Capital Securities Legend;

          (iii) a new Capital Securities Certificate that does not bear a
     Restricted Capital Securities Legend may be issued in exchange for or in
     lieu of a Capital Securities Certificate (other than a Book-Entry Capital
     Securities Certificate) or any portion thereof 

                                       29

 
     that bears such a legend if, in the Depositor's judgment, placing such a
     legend upon such new Capital Securities Certificate is not necessary to
     ensure compliance with the registration requirements of the Securities Act,
     and the Administrators, at the direction of the Depositor, shall execute
     and deliver such a new Capital Securities Certificate as provided in this
     Article V; and

          (iv) notwithstanding the foregoing provisions of this Section 5.5(c),
     a Successor Capital Securities Certificate of a Capital Securities
     Certificate that does not bear a Restricted Capital Securities Legend shall
     not bear such form of legend unless the Depositor has reasonable cause to
     believe that such Successor Capital Securities Certificate is a "restricted
     security" within the meaning of Rule 144 under the Securities Act, in which
     case the Administrators, at the direction of the Depositor, shall execute
     and deliver a new Capital Securities Certificate bearing a Restricted
     Capital Securities Legend in exchange for such Successor Capital Securities
     Certificate as provided in this Article Five.

          (d)    Before registering for transfer or exchange any Capital
Securities Certificates issued in certificated fully registered form as provided
in Sections 5.2, 5.4 or 5.5 of the Trust Agreement, the Property Trustee as
Securities Registrar may require an Opinion of Counsel or other evidence
satisfactory to it (which may include a certificate from such purchaser or
Holder) that such purchaser or Holder is eligible for the exemptive relief
available under U.S. Department of Labor Prohibited Transaction Class Exemption
("PTCE") 96-23, 95-60, 91-38, 90- 1 or 84-14 or another applicable exemption
with respect to such purchase or holding and, in the case of any purchaser or
Holder relying on any exemption other than PTCE 96-23, 95-60, 91-38, 90-1 or 84-
14, an opinion of counsel or other evidence satisfactory to the Property Trustee
with respect to the availability of such exemption. Any purchaser or Holder of
any Capital Securities or any interest therein will be deemed to have
represented by its purchase and holding thereof that it either (i) is not a Plan
or a Plan Asset Entity and is not purchasing such Capital Securities on behalf
of or with "plan assets" of any Plan, or (ii) is eligible for the exemptive
relief available under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or another
applicable exemption with respect to such purchase or holding.

     Section 5.6.  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 Administrators 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
Administrators, or any one of them, on behalf of the Issuer Trust shall execute
and make available for delivery, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Trust Securities Certificate, a new Trust
Securities Certificate of like class, tenor and denomination. In connection with
the issuance 

                                       30

 
of any new Trust Securities Certificate under this Section 5.6, the
Administrators or the Securities Registrar may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection therewith. Any duplicate Trust Securities Certificate issued pursuant
to this Section shall constitute conclusive evidence of an undivided beneficial
interest in the assets of the Issuer Trust corresponding to that evidenced by
the lost, stolen or destroyed Trust Securities Certificate, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

     Section 5.7.  Persons Deemed Holders.

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

     Section 5.8.  Access to List of Holders' Names and Addresses.

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

     Section 5.9.  Maintenance of Office or Agency.

     The Property Trustee shall designate, with the consent of the
Administrators, which consent shall not be unreasonably withheld, an office or
offices or agency or agencies where Capital Securities Certificates may be
surrendered for registration of transfer or exchange and where notices and
demands to or upon the Issuer Trustees in respect of the Trust Securities
Certificates may be served. The Property Trustee initially designates The First
National Bank of Chicago, One First National Plaza, Suite 0126, Chicago,
Illinois 60670, Attention: Corporate Trust Administration, as its office and
agency for such purposes. The Property Trustee shall give prompt written notice
to the Depositor, the Administrators and to the Holders of any change in the
location of the Securities Register or any such office or agency.

     Section 5.10. Appointment of Paying Agent.

     The Paying Agent shall make Distributions to Holders from the Payment
Account and shall report the amounts of such Distributions to the Property
Trustee and the Administrators. Any Paying Agent shall have the revocable power
to withdraw funds from the Payment Account solely for the purpose of making the
Distributions referred to above. The Property Trustee may revoke such power and
remove the Paying Agent in its sole discretion. The Paying Agent shall initially
be the Bank. Any Person acting as Paying Agent shall be permitted to resign as
Paying 

                                       31

 
Agent upon 30 days' written notice to the Administrators and the Property
Trustee. If the Bank shall no longer be the Paying Agent or a successor Paying
Agent shall resign or its authority to act be revoked, the Property Trustee
shall appoint a successor (which shall be a bank or trust company) that is
reasonably acceptable to the Administrators to act as Paying Agent. Such
successor Paying Agent or any additional Paying Agent shall execute and deliver
to the Issuer Trustees an instrument in which such successor Paying Agent or
additional Paying Agent shall agree with the Issuer Trustees that as Paying
Agent, such successor Paying Agent or additional Paying Agent will hold all
sums, if any, held by it for payment to the Holders in trust for the benefit of
the Holders entitled thereto until such sums shall be paid to such Holders. The
Paying Agent shall return all unclaimed funds to the Property Trustee and upon
removal of a Paying Agent such Paying Agent shall also return all funds in its
possession to the Property Trustee. The provisions of Sections 8.1, 8.3 and 8.6
herein shall apply to 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 5.11.  Ownership of Common Securities by Depositor.

     At the Time of Delivery, the Depositor shall acquire, and thereafter shall
retain, beneficial and record ownership of the Common Securities. The Depositor
may not transfer the Common Securities except (i) 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, or (ii) to the Depositor or an Affiliate thereof in compliance with
applicable law (including the Securities Act of 1933, as amended, and applicable
state securities and blue sky laws), and in either case only upon an effective
assignment and delegation by the Holder of the Common Securities to its
transferee of all of its rights and obligations under the Expense Agreement. To
the fullest extent permitted by law, any attempted transfer of the Common
Securities other than as set forth in the next proceeding sentence shall be
void. The Administrators shall cause each Common Securities Certificate issued
to the Depositor to contain a legend stating substantially "THIS CERTIFICATE IS
NOT TRANSFERABLE EXCEPT TO THE DEPOSITOR OR AN AFFILIATE OF THE DEPOSITOR IN
COMPLIANCE WITH APPLICABLE LAW AND SECTION 5.11 OF THE TRUST AGREEMENT AND ONLY
IN CONNECTION WITH A SIMULTANEOUS DELEGATION AND ASSIGNMENT OF THE EXPENSE
AGREEMENT REFERRED TO THEREIN."

     Section 5.12.  Notices to Clearing Agency.

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

                                       32

 
     Section 5.13.  Rights of Holders; Waivers of Past Defaults.

     (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 2.9, and
the Holders shall not have any right or title therein other than the undivided
beneficial interest in the assets of the Issuer Trust conferred by their Trust
Securities and they shall have no right to call for any partition or division of
property, profits or rights of the Issuer Trust except as described below. The
Trust Securities shall be personal property giving only the rights specifically
set forth therein and in this Trust Agreement. The Trust Securities shall have
no preemptive or similar rights and when issued and delivered to Holders against
payment of the purchase price therefor will be fully paid and nonassessable by
the Issuer Trust. The Holders of the Trust Securities, in their capacities as
such, shall be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.

     (b) For so long as any Capital Securities remain Outstanding, if, upon a
Debenture Event of Default, the Debenture Trustee fails or the holders of not
less than 25% in principal amount of the outstanding Debentures fail to declare
the principal of all of the Debentures to be immediately due and payable, the
Holders of at least 25% in Liquidation Amount of the Capital Securities then
Outstanding shall have the right to make such declaration by a notice in writing
to the Property Trustee, the Depositor and the Debenture Trustee.

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

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

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

                 (B) any accrued Additional Interest on all of the Debentures,

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

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

                                       33

 
          (ii) all Events of Default with respect to the Debentures, other than
     the non- payment of the principal of the Debentures that has become due
     solely by such acceleration, have been cured or waived as provided in
     Section 5.13 of the Indenture.

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

     Upon receipt by the Property Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, by Holders of any part of the
Capital Securities a record date shall be established for determining Holders of
Outstanding Capital Securities entitled to join in such notice, which record
date shall be at the close of business on the day the Property Trustee receives
such notice. The Holders on such record date, or their duly designated proxies,
and only such Persons, shall be entitled to join in such notice, whether or not
such Holders remain Holders after such record date; provided, that, unless such
declaration of acceleration, or rescission and annulment, as the case may be,
shall have become effective by virtue of the requisite percentage having joined
in such notice prior to the day that is 90 days after such record date, such
notice of declaration of acceleration, or rescission and annulment, as the case
may be, shall automatically and without further action by any Holder be canceled
and of no further effect. Nothing in this paragraph shall prevent a Holder, or a
proxy of a Holder, from giving, after expiration of such 90-day period, a new
written notice of declaration of acceleration, or rescission and annulment
thereof, as the case may be, that is identical to a written notice that has been
canceled pursuant to the proviso to the preceding sentence, in which event a new
record date shall be established pursuant to the provisions of this Section
5.13(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 any
amounts payable in respect of Debentures having an aggregate principal amount
equal to the aggregate Liquidation Amount of the Capital Securities of such
Holder (a "Direct Action"). Except as set forth in Section 5.13(b) and this
Section 5.13(c), the Holders of Capital Securities shall have no right to
exercise directly any right or remedy available to the holders of, or in respect
of, the Debentures.

     (d) Except as otherwise provided in paragraphs (a), (b) and (c) of this
Section 5.13, the Holders of at least a Majority in Liquidation Amount of the
Capital Securities may, on behalf 

                                       34

 
of the Holders of all the Capital Securities, waive any past default or Event of
Default and its consequences. Upon such waiver, any such default or Event of
Default shall cease to exist, and any default or Event of Default arising
therefrom shall be deemed to have been cured, for every purpose of this Trust
Agreement, but no such waiver shall extend to any subsequent or other default or
Event of Default or impair any right consequent thereon.


                                  ARTICLE VI.

                       Acts of Holders; Meetings; Voting

     Section 6.1.  Limitations on Voting Rights.

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

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

     (c) If any proposed amendment to the Trust Agreement provides for, or the
Issuer Trustees otherwise propose to effect, (i) any action that would adversely
affect in any material 

                                       35

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

     Section 6.2.  Notice of Meetings.

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

     Section 6.3.  Meetings of Holders of the Capital Securities.

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

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

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

                                       36

 
     Section 6.4.  Voting Rights.

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

     Section 6.5.  Proxies, etc.

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

     Section 6.6.  Holder Action by Written Consent.

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

     Section 6.7.  Record Date for Voting and Other Purposes.

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

                                       37

 
     Section 6.8.  Acts of Holders.

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

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

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

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

     If any dispute shall arise among the Holders, the Administrators or the
Issuer Trustees with respect to the authenticity, validity or binding nature of
any request, demand, authorization, direction, consent, waiver or other Act of
such Holder or Issuer Trustee under this Article VI, 

                                       38

 
then the determination of such matter by the Property Trustee shall be
conclusive with respect to such matter.

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

     Section 6.9.  Inspection of Records.

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

                                 ARTICLE VIII.

                    The Issuer Trustees; The Administrators

     Section 8.1.  Certain Duties and Responsibilities.

     (a) The duties and responsibilities of the Issuer Trustees and the
Administrators shall be as provided by this Trust Agreement subject to Section
10.10 hereof. Notwithstanding the foregoing, but subject to Section 8.1(c), no
provision of this Trust Agreement shall require any of the Issuer Trustees or
Administrators to expend or risk its or their own funds or otherwise incur any
financial liability in the performance of any of its or their duties hereunder,
or in the exercise of any of its or their rights or powers, if it or they shall
have reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.
Whether or not therein expressly so provided, every provision of this Trust
Agreement relating to the conduct or affecting the liability of or affording
protection to the Issuer Trustees or the Administrators shall be subject to the
provisions of this Section 8.1. Nothing in this Trust Agreement shall be
construed to release an Administrator from liability for his or her own
negligent action, its own negligent failure to act, or his or her own willful
misconduct. To the extent that, at law or in equity, an Issuer Trustee or
Administrator has duties and liabilities relating to the Issuer Trust or to the
Holders, such Issuer Trustee or Administrator shall not be liable to the Issuer
Trust or to any Holder for such Issuer Trustee's or Administrator'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
Issuer Trustees and Administrators otherwise existing at law or in equity, are
agreed by the Depositor and the Holders to replace such other duties and
liabilities of the Issuer Trustees and Administrators.

     (b) All payments made by the Property Trustee or a Paying Agent in respect
of the Trust Securities shall be made only from the revenue and proceeds from
the Trust Property and only to the extent that there shall be sufficient revenue
or proceeds from the Trust Property to enable the Property Trustee or a Paying
Agent to make payments in accordance with the terms hereof. Each Holder, by its
acceptance of a Trust Security, agrees that it will look solely to the revenue
and proceeds from the Trust Property to the extent legally available for
distribution to it as herein provided and that neither the Issuer Trustees nor
the Administrators are 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 Issuer

                                       41

 
Trustees expressly set forth elsewhere in this Trust Agreement or, in the case
of the Property Trustee, in the Trust Indenture Act.

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

     (d) The Property Trustee, before the occurrence of any Event of Default and
after the curing of all Events of Default that may have occurred, shall
undertake to perform only such duties as are specifically set forth in this
Trust Agreement (including pursuant to Section 10.10), and no implied covenants
shall be read into this Trust Agreement against the Property Trustee. If an
Event of Default has occurred (that has not been cured or waived pursuant to
Section 5.13, the Property Trustee shall exercise such of the rights and powers
vested in it by this Trust Agreement, and use the same degree of care and skill
in its exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

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

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

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

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

                                       42

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

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

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

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

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

     (f) The Administrators shall not be responsible for monitoring the
compliance by the Issuer Trustees or the Depositor with their respective duties
under this Trust Agreement, nor shall either Administrator be liable for the
default or misconduct of any other Administrator, the Issuer Trustees 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 Holders and the Administrators, unless such Event of Default
shall have been cured or waived.

                                       43

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

     The Property Trustee shall not be deemed to have knowledge of any Event of
Default unless the Property Trustee shall have received written notice or a
Responsible Officer of the Property Trustee charged with the administration of
this Trust Agreement shall have obtained actual knowledge of such Event of
Default.

     Section 8.3.  Certain Rights of Property Trustee.

     Subject to the provisions of Section 8.1:

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

     (b) if (i) in performing its duties under this Trust Agreement the Property
Trustee is required to decide between alternative courses of action, (ii) in
construing any of the provisions of this Trust Agreement the Property Trustee
finds the same ambiguous or inconsistent with any other provisions contained
herein, or (iii) the Property Trustee is unsure of the application of any
provision of this Trust Agreement, then, except as to any matter as to which the
Holders of the Capital Securities are entitled to vote under the terms of this
Trust Agreement, the Property Trustee shall deliver a notice to the Depositor
requesting the Depositor's opinion as to the course of action to be taken and
the Property Trustee shall take such action, or refrain from taking such action,
as the Property Trustee shall deem advisable and in the best interests of the
Holders, in which event the Property Trustee shall have no liability except for
its own bad faith, negligence or willful misconduct;

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

     (d) any direction or act of an Administrator contemplated by this Trust
Agreement shall be sufficiently evidenced by a certificate executed by such
Administrator and setting forth such direction or act;

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

                                       44

 
     (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; 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

direction of any of the Holders pursuant to this Trust Agreement, unless such
Holders shall have offered to the Property Trustee reasonable security or
indemnity against the costs, expenses and liabilities that might be incurred by
it in compliance with such request or direction; provided that, nothing
contained in this Section 8.3(g) shall be taken to relieve the Property Trustee,
upon the occurrence of an Event of Default, of its obligation to exercise the
rights and powers vested in it by this Trust Agreement;

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

Trustee shall deem it desirable to receive instructions with respect to
enforcing any remedy or right or taking any other action hereunder, the Property

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.

exercise any right, power, 

                                       45

 
duty or obligation conferred or imposed on it, in any jurisdiction in which it
shall be illegal, or in which such Person shall be unqualified or incompetent in
accordance with applicable law, to perform any such act or acts, or to exercise
any such right, power, duty or obligation. No permissive power or authority
available to any Issuer Trustee or Administrator shall be construed to be a
duty.

     Section 8.4.  Not Responsible for Recitals or Issuance of Securities.

     The recitals contained herein and in the Trust Securities Certificates
shall be taken as the statements of the Issuer Trust and the Depositor, and the

accountable for the use or application by the Depositor of the proceeds of the
Debentures.

     Section 8.5.  May Hold Securities.

     The Administrators, any Issuer Trustee or any other agent of any Issuer

and except as provided in the definition of the term "Outstanding" in Article I,
may otherwise deal with the Issuer Trust with the same rights it would have if
it were not an Administrator, Issuer Trustee or such other agent.

     Section 8.6.  Compensation; Indemnity; Fees.

     The Depositor agrees:

     (a) to pay to the Issuer Trustees from time to time such reasonable
compensation for all services rendered by them hereunder as may be agreed by the

not be limited by any provision of law in regard to the compensation of a
trustee of an express trust);

     (b) except as otherwise expressly provided herein, to reimburse the Issuer
Trustees upon request for all reasonable expenses, disbursements and advances
incurred or made by the Issuer Trustees in accordance with any provision of this

disbursement or advance as may be attributable to their negligence, bad faith or
wilful misconduct; and

     (c) to the fullest extent permitted by applicable law, to indemnify and
hold harmless (i) each Issuer Trustee, (ii) each Administrator, (iii) any
Affiliate of any Issuer Trustee, (iv) any officer, director, shareholder,

kind or nature 

                                       46

 
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Issuer Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Issuer Trust
and in a manner such Indemnified Person reasonably believed to be within the
scope of authority conferred on such Indemnified Person by this Trust Agreement,
except that no Indemnified Person shall be entitled to be indemnified in respect
of any loss, damage or claim incurred by such Indemnified Person by reason of
negligence, bad faith or wilful misconduct with respect to such acts or
omissions.

     The provisions of this Section 8.6 shall survive the termination of this
Trust Agreement and the removal or resignation of any Issuer Trustee or
Administrator, as the case may be.

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

     The Depositor, any Administrator and any Issuer Trustee may engage in or
possess an interest in other business ventures of any nature or description,
independently or with others, similar or dissimilar to the business of the
Issuer Trust, and the Issuer Trust and the Holders of Trust Securities shall
have no rights by virtue of this Trust Agreement in and to such independent
ventures or the income or profits derived therefrom, and the pursuit of any such
venture, even if competitive with the business of the Issuer Trust, shall not be
deemed wrongful or improper. Neither the Depositor, any Administrator nor any
Issuer Trustee shall be obligated to present any particular investment or other
opportunity to the Issuer Trust even if such opportunity is of a character that,
if presented to the Issuer Trust, could be taken by the Issuer Trust, and the
Depositor, any Administrator or any Issuer 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 Issuer
Trustee may engage or be interested in any financial or other transaction with
the Depositor or any Affiliate of the Depositor, or may act as depository for,
trustee or agent for, or act on any committee or body of holders of, securities
or other obligations of the Depositor or its Affiliates.

     Section 8.7.  Corporate Property Trustee Required; Eligibility of Issuer
Trustees and Administrators.

     (a) There shall at all times be a Property Trustee hereunder with respect
to the Trust Securities. The Property Trustee shall be a Person that is a
national or state chartered bank and eligible pursuant to the Trust Indenture
Act to act as such and that has a combined capital and surplus of at least
$50,000,000. If any such Person publishes reports of condition at least
annually, pursuant to law or to the requirements of its supervising or examining
authority, then for the purposes of this Section and to the extent permitted by
the Trust Indenture Act, the combined capital and surplus of such Person shall
be deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Property Trustee with
respect to the Trust Securities shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and
with the effect 

                                       47

 
hereinafter specified in this Article. At the time of appointment, the Property
Trustee must have securities rated in one of the three highest rating categories
by a nationally recognized statistical rating organization.

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

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

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

     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 Property Trustee shall have power to appoint, and
upon the written request of the Property Trustee, the Depositor and the
Administrators shall for such purpose join with the Property Trustee in the
execution, delivery, and performance of all instruments and agreements necessary
or proper to appoint, one or more Persons approved by the Property Trustee
either to act as co-trustee, jointly with the Property Trustee, of all or any
part of such Trust Property, or to the extent required by law to act as separate
trustee of any such property, in either case with such powers as may be provided
in the instrument of appointment, and to vest in such Person or Persons in the
capacity aforesaid, any property, title, right or power deemed necessary or
desirable, subject to the other provisions of this Section. Any co-trustee or
separate trustee appointed pursuant to this Section shall either be (i) a

                                       48

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

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

     (a) The Trust Securities shall be executed by one or more Administrators,
and the Trust Securities shall be delivered by the Property Trustee, and all
rights, powers, duties, and obligations hereunder in respect of the custody of
securities, cash and other personal property held by, or required to be
deposited or pledged with, the Property Trustee specified hereunder shall be
exercised solely by the Property Trustee and not by such co-trustee or separate
trustee.

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

     (c) The Property Trustee at any time, by an instrument in writing executed
by it, with the written concurrence of the Depositor, may accept the resignation
of or remove any co-trustee or separate trustee appointed under this Section,
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 resigning 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

     Section 8.10.  Resignation and Removal; Appointment of Successor.

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

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

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

     If a resigning Issuer Trustee shall fail to appoint a successor, or if an
Issuer Trustee shall be removed or become incapable of acting as Issuer Trustee,
or if a vacancy shall occur in the office of any Issuer Trustee for any cause,
the Holders of the Capital Securities, by Act of the Holders of not less than
25% in aggregate Liquidation Amount of the Capital Securities then Outstanding
delivered to such Relevant Trustee, may appoint a successor Relevant Trustee or
Trustees, and such successor Issuer Trustee shall comply with the applicable
requirements of Section 8.11. If no successor Relevant Trustee shall have been
so appointed by the Holders of the Capital Securities and accepted appointment
in the manner required by Section 8.11, any Holder, on behalf of such Holder and
all others similarly situated, or any other Issuer Trustee, may petition any
court of competent jurisdiction for the appointment of a successor Relevant
Trustee.

     The Property Trustee shall give notice of each resignation and each removal
of an Issuer Trustee and each appointment of a successor Issuer Trustee to all
Holders in the manner provided in Section 10.8 and shall give notice to the
Depositor and to the Administrators. 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.

                                       50

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

     Section 8.11.  Acceptance of Appointment by Successor.

     In case of the appointment hereunder of a successor Relevant Trustee, the
retiring Relevant Trustee and each successor Relevant Trustee with respect to
the Trust Securities shall execute and deliver an amendment hereto wherein each
successor Relevant Trustee shall accept such appointment and which (a) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Relevant Trustee all the rights,
powers, trusts and duties of the retiring Relevant Trustee with respect to the
Trust Securities and the Issuer Trust, and (b) shall add to or change any of the
provisions of this Trust Agreement as shall be necessary to provide for or
facilitate the administration of the Issuer Trust by more than one Relevant
Trustee, it being understood that nothing herein or in such amendment shall
constitute such Relevant Trustees co-trustees and upon the execution and
delivery of such amendment the resignation or removal of the retiring Relevant
Trustee shall become effective to the extent provided therein and each such
successor Relevant Trustee, without any further act, deed or conveyance, shall
become vested with all the rights, powers, trusts and duties of the retiring
Relevant Trustee; but, on request of the Issuer Trust or any successor Relevant
Trustee such retiring Relevant Trustee shall duly assign, transfer and deliver
to such successor Relevant Trustee all Trust Property, all proceeds thereof and
money held by such retiring Relevant Trustee hereunder with respect to the Trust
Securities and the Trust.

     Upon request of any such successor Relevant Trustee, the Issuer Trust shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Relevant Trustee all such rights, powers and trusts
referred to in the 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 Person into which the Property Trustee or the Delaware Trustee may be
merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which such Relevant
Trustee shall be a party, or any Person, succeeding to all or substantially all
the corporate trust business of such Relevant Trustee, shall be the successor of
such Relevant Trustee hereunder, provided that such Person shall be 

                                       51

 
otherwise qualified and eligible under this Article, 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
Issuer Trust.

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

     Section 8.14.  Trustee May File Proofs of Claim.

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

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

     (b) to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Property Trustee and, in the event the
Property Trustee 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.

                                       52

 
     Section 8.15.  Reports by Property Trustee.

     (a) Within 60 days after May 15 of each year commencing with May 15, 1997,
the Property Trustee shall transmit to all Holders in accordance with Section
10.8, and to the Depositor, a brief report dated as of the immediately preceding
May 15 with respect to:

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

          (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 May 15 or, if the Property Trustee has not complied in any
     material respect with such obligations, a description of such
     noncompliance; and

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

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

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

     Section 8.16.  Reports to the Property Trustee.

     Each of the Depositor and the Administrators shall provide to the Property
Trustee such documents, reports and information as required by Section 314 of
the Trust Indenture Act (if any) and the compliance certificate required by
Section 314(a) of the Trust Indenture Act in the form, in the manner and at the
times required by Section 314 of the Trust Indenture Act. The Depositor and the

specifying whether such Person is in compliance with all of the terms and
covenants applicable to such Person hereunder.

     Section 8.17.  Evidence of Compliance with Conditions Precedent.

     Each of the Depositor and the Administrators 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 

                                       53

 
Act. Any certificate or opinion required to be given by an officer pursuant to

     Section 8.18.  Number of Issuer Trustees.

     (a) The number of Issuer Trustees shall be two, provided that the Property
Trustee and the Delaware Trustee may be the same Person.

     (b) If an Issuer Trustee ceases to hold office for any reason, a vacancy
shall occur. The vacancy shall be filled with an Issuer Trustee appointed in
accordance with Section 8.10.

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

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

     Section 8.20.  Appointment of Administrators.

     (a) The Administrators shall initially be Romano L. Peluso and James E.
Murphy, and their successors shall be appointed by the Holders of a Majority in
Liquidation Amount of the Common Securities and resign or be may be removed by

                                  ARTICLE IX.

                      Termination, Liquidation and Merger

     Section 9.1.  Termination Upon Expiration Date.

     Unless earlier terminated, the Issuer Trust shall automatically terminate
on December 30, 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, in its capacity as the Holder of the Common
Securities, unless the Depositor shall transfer the Common Securities as
provided by Section 5.11, in which case this provision shall refer instead to
any such successor Holder of the Common Securities;

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

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

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

                                       55

 
     Section 9.3.  Termination.

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

     Section 9.4.  Liquidation.

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

          (i) state the 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 Debentures, or if
     Section 9.4(d) applies receive a Liquidation Distribution, as the Property
     Trustee (after consultation with the Administrators) shall deem
     appropriate.

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

     (c) Except where Section 9.2(c) or 9.4(d) applies, after the Liquidation
Date, (i) the Trust Securities will no longer be deemed to be Outstanding, (ii)
certificates representing a Like Amount of Debentures will be issued to Holders
of Trust Securities Certificates, upon surrender 

                                       56

 
of such Certificates to the exchange agent for exchange, (iii) any Trust
Securities Certificates not so surrendered for exchange will be deemed to
represent a Like Amount of bearing accrued and unpaid interest in an amount
equal to the accumulated and unpaid Distributions on such Trust Securities
Certificates until such certificates are so surrendered (and until such
certificates are so surrendered, no payments of interest or principal will be
made to Holders of Trust Securities Certificates with respect to such
Debentures) and (iv) all rights of Holders holding Trust Securities will cease,
except the right of such Holders to receive Debentures upon surrender of Trust
Securities Certificates.

     (d) If, notwithstanding the other provisions of this Section 9.4, whether
because of an order for dissolution entered by a court of competent jurisdiction
or otherwise, distribution of the Debentures in the manner provided herein is
determined by the Property Trustee not to be practical, or if an Early
Termination Event specified in clause (c) of Section 9.2 occurs, the Trust
Property shall be liquidated, and the Issuer Trust shall be dissolved, wound-up
or terminated, by the Property Trustee in such manner as the Property Trustee
determines. In such event, on the date of the dissolution, winding-up or other
termination of the Issuer Trust, Holders will be entitled to receive out of the
assets of the Issuer Trust available for distribution to Holders, after
satisfaction of liabilities to creditors of the Issuer Trust as provided by
applicable law, an amount equal to the Liquidation Amount per Trust Security
plus accumulated and unpaid Distributions thereon to the date of payment (such
amount being the "Liquidation Distribution"). If, upon any such dissolution,
winding up or termination, the Liquidation Distribution can be paid only in part
because the Issuer Trust has insufficient assets available to pay in full the
aggregate Liquidation Distribution, then, subject to the next succeeding
sentence, the amounts payable by the Issuer Trust on the Trust Securities shall
be paid on a pro rata basis (based upon Liquidation Amounts). The Holders of the
Common Securities will be entitled to receive Liquidation Distributions upon any
such dissolution, winding-up or termination pro rata (determined as aforesaid)
with Holders of Capital Securities, except that, if a Debenture Event of Default
specified in Section 5.1(1) or 5.1(2) of the Indenture has occurred and is
continuing, the Capital Securities shall have a priority over the Common
Securities as provided in Section 4.3.

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

     The Issuer Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other body, except pursuant
to this Section 9.5. At the request of the Holders of the Common Securities,
with the consent of the Holders of at least a Majority in Liquidation Amount of
the Capital Securities, the Issuer Trust may merge with or into, consolidate,
amalgamate, or be replaced by or convey, transfer or lease its properties and
assets substantially as an entirety to a trust organized as such under the laws
of any State; provided, that (i) such successor entity either (a) expressly
assumes all of the obligations of the Issuer Trust with respect to the Capital
Securities, or (b) substitutes for the Capital Securities other securities

                                       57

 
having substantially the same terms as the Capital Securities (the "Successor
Securities") so long as the Successor Securities have the same priority as the
Capital Securities with respect to distributions and payments upon liquidation,
redemption and otherwise, (ii) a trustee of such successor entity possessing the
same powers and duties as the Property Trustee is appointed to hold the
Debentures, (iii) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not cause the Capital Securities (including
any Successor Securities) to be downgraded by any nationally recognized
statistical rating organization, (iv) such merger, consolidation, amalgamation,
replacement, conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Capital Securities (including
any Successor Securities) in any material respect, (v) such successor entity has
a purpose substantially identical to that of the Issuer Trust, (vi) prior to
such merger, consolidation, amalgamation, replacement, conveyance, transfer or
lease, the Property Trustee has received an Opinion of Counsel to the effect
that (a) such merger, consolidation, amalgamation, replacement, conveyance,
transfer or lease does not adversely affect the rights, preferences and
privileges of the Holders of the Capital Securities (including any Successor
Securities) in any material respect, and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, neither
the Issuer Trust nor such successor entity will be required to register as an
"investment company" under the Investment Company Act, and (vii) the Depositor
or its permitted transferee owns all of the Common Securities of such successor
entity and guarantees the obligations of such successor entity under the
Successor Securities at least to the extent provided by the Guarantee Agreement.
Notwithstanding the foregoing, the Issuer Trust shall not, except with the
consent of holders of all of the Capital Securities, consolidate, amalgamate,
merge with or into, or be replaced by or convey, transfer or lease its
properties and assets substantially as an entirety to any other entity or permit
any other entity to consolidate, amalgamate, merge with or into, or replace it
if such consolidation, amalgamation, merger, replacement, conveyance, transfer
or lease would cause the Issuer Trust or the successor entity to be taxable as a
corporation or classified as other than a grantor trust for United States
Federal income tax purposes.

                           Miscellaneous Provisions

     Section 10.1.  Limitation of Rights of Holders.

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

     Section 10.2.  Amendment.

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

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

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Holder (such consent being
obtained in accordance with Section 6.3 or 6.6 hereof), this Trust Agreement may
not be amended to (i) change the amount or timing of any Distribution on the
Trust Securities or otherwise adversely affect the amount of any Distribution
required to be made in respect of the Trust Securities as of a specified date,
or (ii) restrict the right of a Holder to institute suit for the enforcement of
any such payment on or after such date; and notwithstanding any other provision
herein, without the unanimous consent of the Holders (such consent being
obtained in accordance with Section 6.3 or 6.6 hereof), this paragraph (c) of
this Section 10.2 may not be amended.

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

                                       59

 
     (e) Notwithstanding anything in this Trust Agreement to the contrary,
without the consent of the Depositor and the Administrators, this Trust

Administrators or the Property Trustee shall promptly provide to the Depositor a
copy of such amendment.

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

     Section 10.9.  Agreement Not to Petition.

     Each of the Issuer Trustees and the Depositor agree for the benefit of the
Holders that, until at least one year and one day after the Issuer Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Issuer Trust under any bankruptcy,
insolvency, reorganization or other similar law (including the United States
Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in the
commencement of any proceeding against the Issuer Trust under any Bankruptcy

Property Trustee agrees, for the benefit of Holders, that at the expense of the
Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Issuer
Trust or the commencement of such action and raise the defense that the
Depositor has agreed in writing not to take such action and should be stopped
and precluded therefrom and such other defenses, if any, as counsel for the
Issuer Trustee or the Issuer Trust may assert.

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

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

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

The Depository Trust Company,
  55 Water Street, 49th Floor,
    New York, New York 10041-0099.

Attention:  General Counsel's Office

          Re:  State Street Institutional Capital A
               7.94% Capital Securities, Series A
               CUSIP 85748FAA2 (144A)
               --------------------------------------

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 book-
entry-only portion of the 7.94% Capital Securities, Series A (the "Capital
Securities"), of State Street Institutional Capital A, a statutory business
trust formed under the laws of the State of Delaware (the "Issuer"), governed by
the Amended and Restated Trust Agreement, dated as of December 15, 1996, between
State Street Boston Corporation ("the Corporation"), as Depositor, The First
National Bank of Chicago, as Property Trustee, and First Chicago Delaware Inc.,
as Delaware Trustee. The payment of distributions on the Capital Securities and
payments due upon liquidation of the Issuer or redemption of the Capital
Securities, to the extent the Issuer has funds available for the payment
thereof, are guaranteed by the Corporation to the extent set forth in a
Guarantee Agreement, dated as of December 15, 1996, between the Corporation and
The First National Bank of Chicago, as Guarantee Trustee with respect to the
Capital Securities.  The Corporation and the Issuer propose to sell the Capital
Securities to Goldman, Sachs & Co. and Morgan Stanley & Co. Incorporated (the
"Initial Purchasers") pursuant to a Purchase Agreement, dated December 13, 1996,
by and among the Initial Purchasers, the Issuer and the Corporation, and the
Initial Purchasers wish to take delivery of the Capital Securities through DTC.
The First National Bank of Chicago is acting as transfer agent and registrar
with respect to the Capital Securities (the "Transfer Agent and Registrar").

 
The Depository Trust Company                                                 -2-



          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 and the Transfer Agent and Registrar make the following
representations to DTC:

          (d)  Prior to the closing of the sale of the Capital Securities to the
Initial Purchasers on December 20, 1996, there shall be deposited with, or held
by the Transfer Agent and Registrar as custodian for, DTC one or more global
certificates (individually and collectively, the "Global Certificate")
registered in the name of DTC's nominee, Cede & Co., representing an aggregate
of 200,000 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.

          (e)  The Amended and Restated Trust Agreement of the Issuer provides
for the voting by holders (with no provision for revocation of consents or votes
by subsequent 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.

          (f)  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 as soon as
possible but, at least 5 business days prior to the effective date of such
event.

          (g)  In the event of any 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 

 
The Depository Trust Company                                                 -3-



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

                          [FORM OF EXPENSE AGREEMENT]

                   AGREEMENT AS TO EXPENSES AND LIABILITIES

and conditions hereof, the Common Securityholder hereby irrevocably and
unconditionally guarantees to each person or entity to whom the Issuer 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 Issuer Trust, other than obligations of the Issuer Trust to
pay to holders of any Trust Securities the amounts due such holders pursuant to
the terms of the Trust Securities. 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. Subordination of Guarantee.   The guarantee and other
liabilities and obligations of the Common Securityholder under this Agreement
shall constitute unsecured obligations of the Common Securityholder and shall
rank subordinate and junior in right of payment to all Senior Indebtedness (as
defined in the Indenture) of the Common Securityholder to the extent and in the
manner set forth in the Indenture with respect to the Debentures, and the
provisions of Article XIII of the Indenture will apply, mutatis mutandis, to the
obligations of the Common Securityholder hereunder. The obligations of the
Common Securityholder hereunder do not constitute Senior Indebtedness (as
defined in the Indenture) of the Common Securityholder.

     Section 1.3. 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 the Debentures shall have been distributed to the Holders
of the Trust Securities as provided in Article IX; 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 the Common
Securityholder and The First National Bank of Chicago as guarantee trustee, or
under this Agreement for any reason whatsoever. This Agreement is continuing,
irrevocable, unconditional and absolute.

     Section 1.4. Waiver of Notice. The  Common Securityholder hereby waives
notice of acceptance of this Agreement and of any Obligation to which it applies
or may apply, and the Common Securityholder hereby waives presentment, demand
for payment, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands.

     Section 1.5. No Impairment. The obligations, covenants, agreements and
duties of the Common Securityholder 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 Issuer 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 Issuer Trust granting indulgence or extension of any
kind; or

                                      D-2

 
     (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 Issuer Trust or any of the assets of
the Issuer Trust (other than the liquidation of the Trust in accordance with the
terms thereof).

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

     Section 1.6. Enforcement. A Beneficiary may enforce this Agreement directly
against the Common Securityholder and the Common Securityholder waives any right
or remedy to require that any action be brought against the Issuer Trust or any
other person or entity before proceeding against the Common Securityholder.

     Section 1.7. Subrogation. The Common Securityholder shall be subrogated to
all rights (if any) of the Trust in respect of any amounts paid to the
Beneficiaries by the Common Securityholder under this Agreement; provided,
however, that the Common Securityholder 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. Assignment. This Agreement may not be assigned by either party
hereto without the consent of the other, and any purported assignment without
such consent shall be void; except that upon any transfer of the Common
                            ------                                     
Securities, this Agreement shall be assigned and delegated by the Common
Securityholder to its successor with such transfer without any action by either
party hereto.

     Section 2.2. Binding Effect. All guarantees and agreements contained in
this Agreement shall bind the successors, assigns, receivers, trustees and
representatives of the Common Securityholder and shall inure to the benefit of
the Beneficiaries.

     Section 2.3. Amendment. So long as there remains any Beneficiary or any
Capital Securities 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 without the consent of such Beneficiary or the holders of the
Capital Securities, as the case may be.
