                                      15



          (d) Notwithstanding anything herein to the contrary, the 
Administrative Trustees are authorized and directed to conduct the affairs of 
the Trust and to operate the Trust so that the Trust will not be deemed to be 
an "investment company" required to be registered under the 1940 Act, or fail 
to be classified as 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, 
the Depositor and the Administrative Trustees are authorized to take any 
action, not inconsistent with applicable law, the Certificate of Trust or 
this Trust Agreement, that each of the Depositor and any Administrative 
Trustee determines in its 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 Preferred Securities. 

     Section 2.8 ASSETS OF TRUST.  The assets of the Trust shall consist of 
the Trust Property. 

     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 for the 
benefit of the Trust and the Securityholders in accordance with this Trust 
Agreement.

                                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 any agent of the 
Property Trustee 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 Securityholders and for distribution as 
herein provided, including (and subject to) any priority of payments provided 
for herein. 

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

                                      16



                                  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 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 accrue from 
     ____________, 1997, and, except in the event (and to the extent) that the 
     Depositor exercises its right to defer the payment of interest on the 
     Debentures pursuant to the Indenture, shall be payable quarterly in arrears
     on March 31, June 30, September 30 and December 31 of each year, commencing
     on December 15, 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) except that, if such Business Day is in the next succeeding 
     calendar year, payment of such Distribution shall be made on the 
     immediately preceding Business Day, in each case with the same force and 
     effect as if made on such date (each date on which distributions are 
     payable in accordance with this Section 4.1(a), a "Distribution Date"). 

               (ii) Assuming payments of interest on the Debentures are made 
     when due (and before giving effect to Additional Amounts, if applicable), 
     Distributions on the Trust Securities shall be payable at a rate of ___% 
     per annum of the Liquidation Amount of the Trust Securities.  The amount of
     Distributions payable for any full period shall be computed on the basis of
     a 360-day year of twelve 30-day months.  The amount of Distributions for 
     any partial period shall be computed on the basis of the number of days 
     elapsed in a 360-day year of twelve 30-day months.  The amount of 
     Distributions payable for any period shall include the Additional Amounts, 
     if any. 

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

                                      17



          (b) Distributions on the Trust Securities with respect to a 
Distribution Date shall be payable to the Holders thereof as they appear on 
the Securities Register for the Trust Securities on the relevant record date, 
which shall be one Business Day prior to such Distribution Date; provided, 
however, that in the event that the Preferred Securities do not remain in 
book- entry-only form, the relevant record date shall be the date 15 days 
prior to the relevant Distribution Date. 

     Section 4.2 REDEMPTION.

          (a) On each Debenture Redemption Date and on the stated maturity of 
the Debentures, the Trust will be required to redeem, subject to Section 4.3, 
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; 

               (iii) the CUSIP number; 

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

               (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 accrue on and after said date. 

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

          (d) If the Property Trustee gives a notice of redemption in respect 
of any Preferred Securities, then, by 12:00 noon, Rocky Mountain time, on the 
Redemption Date, subject to Section 4.2(c), with respect to Preferred 
Securities held in book-entry form, the Property Trustee will irrevocably 
deposit with the Clearing Agency for the Preferred Securities funds 
sufficient to pay the applicable Redemption Price and will give such Clearing 
Agency irrevocable 

                                      18



instructions and authority to pay the Redemption Price to the holders 
thereof.  With respect to Preferred Securities held in certificated form, the 
Property Trustee, subject to Section 4.2(c), will irrevocably deposit with 
the Paying Agent funds sufficient to pay the applicable Redemption Price and 
will give the Paying Agent irrevocable instructions and authority to pay the 
Redemption Price to the Holders thereof upon surrender of their Preferred 
Securities Certificates. Notwithstanding the foregoing, Distributions payable 
on or prior to the Redemption Date for any Trust Securities called for 
redemption shall be payable to the Holders of such Trust Securities as they 
appear on the Register for the Trust Securities on the relevant record dates 
for the related Distribution Dates.  If notice of redemption shall have been 
given and funds deposited as required, then upon the date of such deposit, 
all rights of Securityholders holding Trust Securities so called for 
redemption will cease, except the right of such Securityholders to receive 
the Redemption Price and any Distribution payable 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 
(and without any interest or other payment in respect of any such delay), 
except that, if such Business Day falls in the next calendar year, such 
payment will be made on the immediately preceding Business Day, in each case, 
with the same force and effect as if made on such date.  In the event that 
payment of the Redemption Price in respect of any Trust Securities called for 
redemption is improperly withheld or refused and not paid either by the Trust 
or by the Depositor pursuant to the Guarantee, Distributions on such Trust 
Securities will continue to accrue, at the then applicable rate, from the 
Redemption Date originally established by the Trust for such Trust Securities 
to the date such Redemption Price is actually paid, in which case the actual 
payment date will be the date fixed for redemption for purposes of 
calculating the Redemption Price. 

          (e) Payment of the Redemption Price on the Trust Securities shall 
be made to the recordholders thereof as they appear on the Securities 
Register for the Trust Securities on the relevant record date, which shall be 
one Business Day prior to the relevant Redemption Date; provided, however, 
that in the event that the Preferred Securities do not remain in 
book-entry-only form, the relevant record date shall be the date fifteen days 
prior to the relevant Redemption Date. 

          (f) 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 on a 
pro rata basis (based on Liquidation Amounts) among the Common Securities and 
the Preferred Securities.  The particular Preferred Securities to be redeemed 
shall be selected on a pro rata basis (based upon Liquidation Amounts) not 
more than 60 days prior to the Redemption Date by the Property Trustee from 
the Outstanding Preferred Securities not previously called for redemption, by 
such method 

                                      19



(including, without limitation, by lot) as the Property Trustee shall deem 
fair and appropriate and which may provide for the selection for redemption 
of portions (equal to $25 or an integral multiple of $25 in excess thereof) 
of the Liquidation Amount of Preferred Securities of a denomination larger 
than $25.  The Property Trustee shall promptly notify the Security Registrar 
in writing of the Preferred Securities selected for redemption and, in the 
case of any Preferred Securities selected for partial redemption, the 
Liquidation Amount thereof to be redeemed.  For all purposes of this Trust 
Agreement, unless the context otherwise requires, all provisions relating to 
the redemption of Preferred Securities shall relate, in the case of any 
Preferred Securities redeemed or to be redeemed only in part, to the portion 
of the Liquidation Amount of Preferred Securities that has been or is to be 
redeemed. 

     Section 4.3 SUBORDINATION OF COMMON SECURITIES.

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

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

                                      20



     Section 4.4 PAYMENT PROCEDURES.  Payments of Distributions (including 
Additional Amounts, if applicable) in respect of the Preferred Securities 
shall be made by check mailed to the address of the Person entitled thereto 
as such address shall appear on the Securities Register or, if the Preferred 
Securities are held by a Clearing Agency, such Distributions shall be made to 
the Clearing Agency in immediately available funds, which shall credit the 
relevant Persons' accounts at such Clearing Agency on the applicable 
Distribution Dates.  Payments in respect of the Common Securities shall be 
made in such manner as shall be mutually agreed between the Property Trustee 
and the Common Securityholder. 

     Section 4.5 TAX RETURNS AND REPORTS.  The Administrative Trustees shall 
prepare (or cause to be prepared), at the Depositor's expense, and file all 
United States Federal, state and local tax and information returns and 
reports required to be filed by or in respect of the Trust.  In this regard, 
the Administrative Trustees shall (a) prepare and file (or cause to be 
prepared and filed) the appropriate Internal Revenue Service form required to 
be filed in respect of the Trust in each taxable year of the Trust and (b) 
prepare and furnish (or cause to be prepared and furnished) to each 
Securityholder the appropriate Internal Revenue Service form required to be 
provided on such form.  The Administrative Trustees shall provide the 
Depositor and the Property Trustee with a copy of all such returns and 
reports promptly after such filing or furnishing.  The Trustees shall comply 
with United States Federal withholding and backup withholding tax laws and 
information reporting requirements with respect to any payments to 
Securityholders under the Trust Securities. 

     Section 4.6 PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST.  Upon receipt 
under the Debentures of Additional Sums, the Property Trustee shall promptly 
pay any taxes, duties or governmental charges of whatsoever nature (other 
than withholding taxes) imposed on the Trust by the United States or any 
other taxing authority. 

     Section 4.7 PAYMENTS UNDER INDENTURE OR PURSUANT TO DIRECT ACTIONS.  Any 
amount payable hereunder to any Holder of Preferred Securities (and any Owner 
with respect thereto) shall be reduced by the amount of any corresponding 
payment such Holder (and Owner) has directly received pursuant to Section 5.8 
of the Indenture or Section 5.14 of this Trust Agreement.

                      TRUST SECURITIES CERTIFICATES

     Section 5.1 INITIAL OWNERSHIP.  Upon the formation of the Trust and the 
contribution by the Depositor pursuant to Section 2.3 and until the issuance 
of the Trust Securities, and at any time during which no Trust Securities are 
outstanding, the Depositor shall be the sole beneficial owner of the Trust. 

                                      21



     Section 5.2 THE TRUST SECURITIES CERTIFICATES.  The Preferred Securities 
Certificates shall be issued in minimum denominations of $25 Liquidation 
Amount and integral multiples of $25 in excess thereof, and the Common 
Securities Certificates shall be issued in denominations of $25 Liquidation 
Amount and integral multiples thereof.  The Trust Securities Certificates 
shall be executed on behalf of the Trust by manual signature of at least one 
Administrative Trustee.  Trust Securities Certificates bearing the manual 
signatures of individuals who were, at the time when such signatures shall 
have been affixed, authorized to sign on behalf of the Trust, shall be 
validly issued and entitled to the benefits of this Trust Agreement, 
notwithstanding that such individuals or any of them shall have ceased to be 
so authorized prior to the delivery of such Trust Securities Certificates or 
did not hold such offices at the date of delivery of such Trust Securities 
Certificates.  A transferee of a Trust Securities Certificate shall become a 
Securityholder, and shall be entitled to the rights and subject to the 
obligations of a Securityholder hereunder, upon due registration of such 
Trust Securities Certificate in such transferee's name pursuant to Sections 
5.4, 5.11 and 5.13. 

     Section 5.3 EXECUTION AND DELIVERY OF TRUST SECURITIES CERTIFICATES.  At 
the Closing Date, the Administrative Trustees shall cause Trust Securities 
Certificates, in an aggregate Liquidation Amount as provided in Section 2.4, 
to be executed on behalf of the Trust and delivered to or upon the written 
order of the Depositor, signed by its chairman of the board, its president, 
any executive vice president or any vice president, treasurer or assistant 
treasurer or controller without further corporate action by the Depositor, in 
authorized denominations. 

     Section 5.4 REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED 
SECURITIES CERTIFICATES.  The Depositor shall keep or cause to be kept, at 
the office or agency maintained pursuant to Section 5.8, a register or 
registers for the purpose of registering Trust Securities Certificates and 
transfers and exchanges of Preferred Securities Certificates (the "Securities 
Register") in which, the registrar designated by the Depositor (the 
"Securities Registrar"), subject to such reasonable regulations as it may 
prescribe, shall provide for the registration of Preferred Securities 
Certificates and Common Securities Certificates (subject to Section 5.10 in 
the case of the Common Securities Certificates) and registration of transfers 
and exchanges of Preferred Securities Certificates as herein provided.  The 
Bank shall be the initial Securities Registrar. 

     Upon surrender for registration of transfer of any Preferred Securities 
Certificate at the office or agency maintained pursuant to Section 5.8, the 
Administrative Trustees or any one of them shall execute and deliver, in the 
name of the designated transferee or transferees, one or more new Preferred 
Securities Certificates in authorized denominations of a like aggregate 
Liquidation Amount dated the date of execution by such Administrative Trustee 
or Trustees. 

     The Securities Registrar shall not be required to register the transfer 
of any Preferred Securities that have been called for redemption.  At the 
option of a 

                                      22



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

     Every Preferred Securities Certificate presented or surrendered for 
registration of transfer or exchange shall be accompanied by a written 
instrument of transfer in form satisfactory to an Administrative Trustee and 
the Securities Registrar duly executed by the Holder or his attorney duly 
authorized in writing.  Each Preferred Securities Certificate surrendered for 
registration of transfer or exchange shall be canceled and subsequently 
disposed of by an Administrative Trustee in accordance with such Person's 
customary practice.  The Trust shall not be required to (i) issue, register 
the transfer of or exchange any Preferred Securities during a period 
beginning at the opening of business 15 calendar days before the date of 
mailing of a notice of redemption of any Preferred Securities called for 
redemption and ending at the close business on the day of such mailing or 
(ii) register the transfer of or exchange any Preferred Securities so 
selected for redemption, in whole or in part, except the unredeemed portion 
of any such Preferred Securities being redeemed in part. 

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

     Section 5.5 MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES 
CERTIFICATES.  If (a) any mutilated Trust Securities Certificate shall be 
surrendered to the Securities Registrar, or if the Securities Registrar shall 
receive evidence to its satisfaction of the destruction, loss or theft of any 
Trust Securities Certificate and (b) there shall be delivered to the 
Securities Registrar and the Administrative Trustees such security or 
indemnity as may be required by them to save each of them harmless, then in 
the absence of notice that such Trust Securities Certificate shall have been 
acquired by a bona fide purchaser, the Administrative Trustees, or any one of 
them, on behalf of the Trust shall execute and make available for delivery, 
in exchange for or in lieu of any such mutilated, destroyed, lost or stolen 
Trust Securities Certificate, a new Trust Securities Certificate of like 
class, tenor and denomination.  In connection with the issuance of any new 
Trust Securities Certificate under this Section, the Administrative Trustees 
or the Securities Registrar may require the payment of a sum sufficient to 
cover any tax or other governmental charge that may be imposed in connection 
therewith.  Any duplicate Trust Securities Certificate issued pursuant to 
this Section shall constitute conclusive evidence of an undivided beneficial 
interest in the assets of the Trust, as if originally issued, whether or not 
the lost, stolen or destroyed Trust Securities Certificate shall be found at 
any time. 


                                      23



    Section 5.6   PERSONS DEEMED SECURITYHOLDERS.  The Trustees or the 
Securities Registrar shall treat the Person in whose name any Trust 
Securities Certificate shall be registered in the Securities Register as the 
owner of such Trust Securities Certificate for the purpose of receiving 
Distributions and for all other purposes whatsoever, and neither the Trustees 
nor the Securities Registrar shall be bound by any notice to the contrary. 

    Section 5.7   ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.  At 
any time when the Property Trustee is not also acting as the Securities 
Registrar, the Administrative Trustees or the Depositor shall furnish or 
cause to be furnished to the Property Trustee (a) semi-annually on or before 
January 1 and July 1 in each year, a list, in such form as the Property 
Trustee may reasonably require, of the names and addresses of the 
Securityholders as of the most recent Record Date and (b) promptly after 
receipt by any Administrative Trustee or the Depositor of a request therefor 
from the Property Trustee, such other information as the Property Trustee may 
reasonably require in order to enable the Property Trustee to discharge its 
obligations under this Trust Agreement, in each case to the extent such 
information is in the possession or control of the Administrative Trustees or 
the Depositor and is not identical to a previously supplied list or has not 
otherwise been received by the Property Trustee in its capacity as Securities 
Registrar.  The rights of Securityholders to communicate with other Security 
holders with respect to their rights under this Trust Agreement or under the 
Trust Securities, and the corresponding rights of the Trustee shall be as 
provided in the Trust Indenture Act. Each Holder, by receiving and holding a 
Trust Securities Certificate, and each Owner shall be deemed to have agreed 
not to hold the Depositor, the Property Trustee or the Administrative 
Trustees accountable by reason of the disclosure of its name and address, 
regardless of the source from which such information was derived. 

    Section 5.8   MAINTENANCE OF OFFICE OR AGENCY.  The Administrative 
Trustees shall maintain an office or offices or agency or agencies where 
Preferred Securities Certificates may be surrendered for registration of 
transfer or exchange and where notices and demands to or upon the Trustees in 
respect of the Trust Securities Certificates may be served.  The 
Administrative Trustees initially designate the principal corporate trust 
office of the Property Trustee, Rodney Square North, 1100 North Market 
Street, Wilmington, Delaware 19890, Attention: Corporate Trust Administrator, 
as the principal corporate trust office for such purposes.  The 
Administrative Trustees shall give prompt written notice to the Depositor and 
to the Securityholders of any change in the location of the Securities 
Register or any such office or agency. 

    Section 5.9   APPOINTMENT OF PAYING AGENT.  The Paying Agent shall make 
Distributions to Securityholders from the Payment Account and shall report 
the amounts of such Distributions to the Property Trustee and the 
Administrative Trustees.  Any Paying Agent shall have the revocable power to 
withdraw funds from the Payment Account for the purpose of making the 
Distributions referred to 

                                     24



above.  The Administrative Trustees may revoke such power and remove the 
Paying Agent if such Trustees determine in their sole discretion that the 
Paying Agent shall have failed to perform its obligations under this Trust 
Agreement in any material respect.  The Paying Agent shall initially be the 
Property Trustee, and any co-paying agent chosen by the Property Trustee, and 
acceptable to the Administrative Trustees and the Depositor.  Any Person 
acting as Paying Agent shall be permitted to resign as Paying Agent upon 30 
days' written notice to the Administrative Trustees, the Property Trustee and 
the Depositor. In the event that the Property Trustee shall no longer be the 
Paying Agent or a successor Paying Agent shall resign or its authority to act 
be revoked, the Administrative Trustees shall appoint a successor that is 
acceptable to the Property Trustee and the Depositor to act as Paying Agent 
(which shall be a bank or trust company).  The Administrative Trustees shall 
cause such successor Paying Agent or any additional Paying Agent appointed by 
the Administrative Trustees to execute and deliver to the Trustees an 
instrument in which such successor Paying Agent or additional Paying Agent 
shall agree with the Trustees that as Paying Agent, such successor Paying 
Agent or additional Paying Agent will hold all sums, if any, held by it for 
payment to the Securityholders in trust for the benefit of the 
Securityholders entitled thereto until such sums shall be paid to such 
Securityholders. The Paying Agent shall return all unclaimed funds to the 
Property Trustee and upon removal of a Paying Agent such Paying Agent shall 
also return all funds in its possession to the Property Trustee. The 
provisions of Sections 8.1, 8.3 and 8.6 herein shall apply to the Bank also 
in its role as Paying Agent, for so long as the Bank shall act as Paying 
Agent and, to the extent applicable, to any other paying agent appointed 
hereunder. Any reference in this Agreement to the Paying Agent shall include 
any co-paying agent unless the context requires otherwise. 

    Section 5.10  OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.  At the 
Closing Date, the Depositor shall acquire and retain beneficial and record 
ownership of the Common Securities.  To the fullest extent permitted by law, 
other than a transfer in connection with a consolidation or merger of the 
Depositor into another corporation, or any conveyance, transfer or lease by 
the Depositor of its properties and assets substantially as an entirety to 
any Person, pursuant to Section 8.1 of the Indenture, any attempted transfer 
of the Common Securities shall be void.  The Administrative Trustees shall 
cause each Common Securities Certificate issued to the Depositor to contain a 
legend stating "THIS CERTIFICATE IS NOT TRANSFERABLE". 

    Section 5.11  BOOK ENTRY PREFERRED SECURITIES CERTIFICATES; COMMON 
SECURITIES CERTIFICATE.

          (a)   The Preferred Securities Certificates, upon original 
issuance, will be issued in the form of a typewritten Preferred Securities 
Certificate or Certificates representing Book-Entry Preferred Securities 
Certificates, to be delivered to The Depository Trust Company, the initial 
Clearing Agency, by, or on behalf of, the Trust.  Such Preferred Securities 
Certificate or Certificates shall 

                                     25




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

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

                (ii)  the Securities Registrar, the Paying Agent and the 
Trustees shall be entitled to deal with the Clearing Agency for all purposes 
of this Trust Agreement relating to the Book-Entry Preferred Securities 
Certificates (including the payment of the Liquidation Amount of and 
Distributions on the Preferred Securities evidenced by Book-Entry Preferred 
Securities Certificates) the Book-Entry Preferred Securities Certificates and 
shall have no obligations to the Owners thereof; 

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

                (iv)  the rights of the Owners of the Book-Entry Preferred 
Securities Certificates shall be exercised only through the Clearing Agency 
and shall be limited to those established by law and agreements between such 
Owners and the Clearing Agency and/or the Clearing Agency Participants.  
Pursuant to the Certificate Depository Agreement, unless and until Definitive 
Preferred Securities Certificates are issued pursuant to Section 5.13, the 
initial Clearing Agency will make book-entry transfers among the Clearing 
Agency Participants and receive and transmit payments on the Preferred 
Securities to such Clearing Agency Participants. Any Clearing Agency 
designated pursuant here to will not be deemed an agent of the Trustee for 
any purpose. 

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

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

                                     26




    Section 5.13  Definitive Preferred Securities Certificates.  If (a) the 
Depositor advises the Trustees in writing that the Clearing Agency is no 
longer willing or able to properly discharge its responsibilities with 
respect to the Preferred Securities Certificates, and the Depositor is unable 
to locate a qualified successor, (b) the Depositor at its option advises the 
Trustees in writing that it elects to terminate the book-entry system through 
the Clearing Agency or (c) after the occurrence of a Debenture Event of 
Default, Owners of Preferred Securities Certificates representing beneficial 
interests aggregating at least a majority of the Liquidation Amount advise 
the Property Trustee in writing that the continuation of a book-entry system 
through the Clearing Agency is no longer in the best interest of the Owners 
of Preferred Securities Certificates, then the Property Trustee shall notify 
the Clearing Agency and the Clearing Agency shall notify all Owners of 
Preferred Securities Certificates and the other Trustees of the occurrence of 
any such event and of the availability of the Definitive Preferred Securities 
Certificates to Owners of such class or classes, as applicable, requesting 
the same.  Upon surrender to the Property Trustee of the typewritten 
Preferred Securities Certificate or Certificates representing the Book Entry 
Preferred Securities Certificates by the Clearing Agency, accompanied by 
registration instructions, the Administrative Trustees, or any one of them, 
shall execute the Definitive Preferred Securities Certificates in accordance 
with the instructions of the Clearing Agency.  Neither the Securities 
Registrar nor the Trustees shall be liable for any delay in delivery of such 
instructions and may conclusively rely on, and shall be protected in relying 
on, such instructions.  Upon the issuance of Definitive Preferred Securities 
Certificates, the Trustees shall recognize the Holders of the Definitive 
Preferred Securities Certificates as Securityholders.  The Definitive 
Preferred Securities Certificates shall be printed, lithographed or engraved 
or may be produced in any other manner as is reasonably acceptable to the 
Administrative Trustees, as evidenced by the execution thereof by the 
Administrative Trustees or any one of them. 

    Section 5.14  RIGHTS OF SECURITYHOLDERS.

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

                                       27



          (b)   For so long as any Preferred Securities remain Outstanding, 
if, upon a Debenture Event of Default, the Debenture Trustee fails or the 
holders of not less than 25% in principal amount of the outstanding 
Debentures fail to declare the principal of all of the Debentures to be 
immediately due and payable, the Holders of at least 25% in Liquidation 
Amount of the Preferred Securities then Outstanding shall have such right by 
a notice in writing to the Depositor and the Debenture Trustee; and upon any 
such declaration such principal amount of and the accrued interest on all of 
the Debentures shall become immediately due and payable, provided that the 
payment of principal and interest on such Debentures shall remain 
subordinated to the extent provided in the Indenture. 

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

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

                      (A)   all overdue installments of interest (including 
any Additional Interest (as defined in the Indenture)) on all of the 
Debentures, 

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

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

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

The holders of a majority in aggregate Liquidation Amount of the Preferred 
Securities may, on behalf of the Holders of all the Preferred 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 

                                     28




has been deposited with the Debenture Trustee) or a default in respect of a 
covenant or provision which under the Indenture cannot be modified or amended 
without the consent of the holder of each outstanding Debenture. No such 
rescission shall affect any subsequent default or impair any right consequent 
thereon. 

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

          (c)   For so long as any Preferred 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 Preferred Securities 
shall have the right to institute a proceeding directly against the 
Depositor, pursuant to Section 5.8 of the Indenture, for enforcement of 
payment to such Holder of the principal amount of or interest on Debentures 
having a principal amount equal to the Liquidation Amount of the Preferred 
Securities of such Holder (a "Direct Action").  Except as set forth in 
Section 5.14(b) and this Section 5.14(c), the Holders of Preferred Securities 
shall have no right to exercise directly any right or remedy available to the 
holders of, or in respect of, the Debentures. 

                                    ARTICLE VI.
                    ACTS OF SECURITYHOLDERS; MEETINGS; VOTING

     Section 6.1  LIMITATIONS ON VOTING RIGHTS.  

          (a)     Except as provided in this Section, in Sections 5.14, 8.10 
and 10.2 and in the Indenture and as otherwise required by law, no Holder of 

                                     29




Preferred Securities shall have any right to vote or in any manner otherwise 
control the administration, operation and management of the Trust or the 
obligations of the parties hereto, nor shall anything herein set forth, or 
contained in the terms of the Trust Securities Certificates, be construed so 
as to constitute the Securityholders from time to time as partners or members 
of an association. 

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

          (c)     If any proposed amendment to the Trust Agreement provides 
for, or the Trustees otherwise propose to effect, (i) any action that would 
adversely affect in any material respect the powers, preferences or special 
rights of the Preferred Securities, whether by way of amendment to the Trust 
Agreement or otherwise, or (ii) the dissolution, winding-up or termination of 
the Trust, other than pursuant to the terms of this Trust Agreement, then the 
Holders of Outstanding Preferred Securities as a class will be entitled to 
vote on such amendment or proposal and such amendment or proposal shall not 
be effective except with the approval of the Holders of at least a majority 
in Liquidation Amount of the Outstanding Preferred Securities.  
Notwithstanding any other provision of this Trust Agreement, no amendment to 
this Trust Agreement may be made if, as a result of such amendment, it would 
cause the Trust to fail to be classified as a grantor trust for United States 
Federal income tax purposes. 

                                     30




    Section 6.2   NOTICE OF MEETINGS.  Notice of all meetings of the 
Preferred Securityholders, stating the time, place and purpose of the 
meeting, shall be given by the Property Trustee pursuant to Section 10.8 to 
each Preferred Securityholder of record, at his registered address, at least 
15 days and not more than 90 days before the meeting.  At any such meeting, 
any business properly before the meeting may be so considered whether or not 
stated in the notice of the meeting.  Any adjourned meeting may be held as 
adjourned without further notice. 

    Section 6.3  MEETINGS OF PREFERRED SECURITYHOLDERS.  No annual meeting of 
Securityholders is required to be held.  The Administrative Trustees, 
however, shall call a meeting of Preferred Securityholders to vote on any 
matter upon the written request of Holders of record of 25% of the 
Outstanding Preferred Securities (based upon their Liquidation Amount) and 
the Administrative Trustees or the Property Trustee may, at any time in their 
discretion, call a meeting of Preferred Securityholders to vote on any 
matters as to which Preferred Securityholders are entitled to vote. 

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

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

    Section 6.4   VOTING RIGHTS.  Securityholders shall be entitled to one 
vote for each $25 of Liquidation Amount represented by their Trust Securities 
in respect of any matter as to which such Securityholders are entitled to 
vote. Section 6.5 Proxies, Etc.  At any meeting of Securityholders, any 
Securityholder entitled to vote thereat may vote by proxy, provided that no 
proxy shall be voted at any meeting unless it shall have been placed on file 
with the Administrative Trustees, or with such other officer or agent of the 
Trust as the Administrative Trustees may direct, for verification prior to 
the time at which such vote shall be taken. Pursuant to a resolution of the 
Property Trustee, proxies may be solicited in the name of the Property 
Trustee or one or more officers of the Property Trustee.  Only 
Securityholders of record shall be entitled to vote.  When Trust Securities 
are held jointly by several persons, any one of them may vote at any meeting 
in person or by proxy in respect of such Trust Securities, but if more than 
one of them shall be present at such meeting in person or by proxy, and such 
joint owners or their proxies so present disagree as to any vote to be cast, 
such vote shall not be received in respect of such Trust Securities.  A proxy 
purporting to be executed by or on behalf of a Securityholder shall be deemed 

                                     31




valid unless challenged at or prior to its exercise, and the burden of 
proving invalidity shall rest on the challenger.  No proxy shall be valid 
more than three years after its date of execution. 

    Section 6.6   SECURITYHOLDER ACTION BY WRITTEN CONSENT.  Any action which 
may be taken by Securityholders at a meeting may be taken without a meeting 
if Securityholders holding more than a majority of all Outstanding Trust 
Securities (based upon their aggregate Liquidation Amount) entitled to vote 
in respect of such action (or such larger proportion thereof as shall be 
required by any express provision of this Trust Agreement) shall consent to 
the action in writing (based upon their aggregate Liquidation Amount). 

    Section 6.7   RECORD DATE FOR VOTING AND OTHER PURPOSES  For the purposes 
of determining the Securityholders who are entitled to notice of and to vote 
at any meeting or by written consent, or to participate in any Distribution 
on the Trust Securities in respect of which a record date is not otherwise 
provided for in this Trust Agreement, or for the purpose of any other action, 
the Administrative Trustees may from time to time fix a date, not more than 
90 days prior to the date of any meeting of Securityholders or the payment of 
a Distribution or other action, as the case may be, as a record date for the 
determination of the identity of the Securityholders of record for such 
purposes. 

    Section 6.8   ACTS OF SECURITYHOLDERS.  Any request, demand, 
authorization, direction, notice, consent, waiver or other action provided or 
permitted by this Trust Agreement to be given, made or taken by 
Securityholders or Owners may be embodied in and evidenced by one or more 
instruments of substantially similar tenor signed by such Securityholders or 
Owners in person or by an agent duly appointed in writing; and, except as 
otherwise expressly provided herein, such action shall become effective when 
such instrument or instruments are delivered to an Administrative Trustee.  
Such instrument or instruments (and the action embodied therein and evidenced 
thereby) are herein sometimes referred to as the "Act" of the Securityholders 
or Owners signing such instrument or instruments.  Proof of execution of any 
such instrument or of a writing appointing any such agent shall be sufficient 
for any purpose of this Trust Agreement and (subject to Section 8.1) 
conclusive in favor of the Trustees, if made in the manner provided in this 
Section. 

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

                                    32




Person executing the same, may also be proved in any other manner which any 
Trustee receiving the same deems sufficient. 

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

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

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

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

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

    Section 6.9   INSPECTION OF RECORDS.  Upon reasonable notice to the 
Administrative Trustees and the Property Trustee, the records of the Trust 
shall be open to inspection by Securityholders during normal business hours 
for any purpose reasonably related to such Securityholder's interest as a 
Securityholder. 

                                   ARTICLE VII.

into or perform its obligations as one of the Trustees under this Trust

                               THE TRUSTEES

    Section 8.1   CERTAIN DUTIES AND RESPONSIBILITIES.

          (a)     The duties and responsibilities of the Trustees shall be as 
provided by this Trust Agreement and, in the case of the Property Trustee, by 
the Trust Indenture Act.  Notwithstanding the foregoing, no provision of this 
Trust Agreement shall require the Trustees to expend or risk their own funds 
or otherwise incur any financial liability in the performance of any of their 
duties hereunder, or in the exercise of any of their rights or powers, if 
they shall have reasonable grounds for believing that repayment of such funds 
or adequate indemnity against such risk or liability is not reasonably 
assured to it.  Whether or 

                                     35




not therein expressly so provided, every provision of this Trust Agreement 
relating to the conduct or affecting the liability of or affording protection 
to the Trustees shall be subject to the provisions of this Section. Nothing 
in this Trust Agreement shall be construed to release an Administrative 
Trustee from liability for its own gross negligent action, its own gross 
negligent failure to act, or its own willful misconduct.  To the extent that, 
at law or in equity, an Administrative Trustee has duties (including 
fiduciary duties) and liabilities relating thereto to the Trust or to the 
Securityholders, such Administrative Trustee shall not be liable to the Trust 
or to any Securityholder for such Trustee's good faith reliance on the 
provisions of this Trust Agreement.  The provisions of this Trust Agreement, 
to the extent that they restrict the duties and liabilities of the 
Administrative Trustees otherwise existing at law or in equity, are agreed by 
the Depositor and the Securityholders to replace such other duties and 
liabilities of the Administrative Trustees. 

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

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

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

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

                                     36




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

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

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

    Section 8.2   CERTAIN NOTICES.

          (a)     Within five Business Days after the occurrence of any Event 
of Default actually known to the Property Trustee, the Property Trustee shall 
transmit, in the manner and to the extent provided in Section 10.8, notice of 
such Event of Default to the Securityholders, the Administrative Trustees and 
the Depositor, unless the Event of Default shall have been cured or waived.   
For purposes of this Section the term "Event of Default" means any event that 
is, or after notice or lapse of time or both would become, and Event of 
Default. 

          (b)     The Administrative Trustees shall transmit, to the 
Securityholders in the manner and to the extent provided in Section 10.8, 
notice of the Depositor's election to begin or further extend an Extension 
Period on the Debentures (unless such election shall have been revoked) 
within the time specified for transmitting such notice to the holders of the 
Debentures pursuant to the Indenture as originally executed. 

    Section 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 

                                     37




or other paper or document believed by it to be genuine and to have been 
signed or presented by the proper party or parties; 

          (b)     if (i) in performing its duties under this Trust Agreement 
the Property Trustee is required to decide between alternative courses of 
action or (ii) in construing any of the provisions of this Trust Agreement 
the Property Trustee finds the same ambiguous or inconsistent with any other 
provisions contained herein or (iii) the Property Trustee is unsure of the 
application of any provision of this Trust Agreement, then, except as to any 
matter as to which the Preferred Securityholders are entitled to vote under 
the terms of this Trust Agreement, the Property Trustee shall deliver a 
notice to the Depositor requesting written instructions of the Depositor as 
to the course of action to be taken and the Property Trustee shall take such 
action, or refrain from taking such action, as the Property Trustee shall be 
instructed in writing to take, or to refrain from taking, by the Depositor; 
provided, however, that if the Property Trustee does not receive such 
instructions of the Depositor within ten Business Days after it has delivered 
such notice, or such reasonably shorter period of time set forth in such 
notice (which to the extent practicable shall not be less than two Business 
Days), it may, but shall be under no duty to, take or refrain from taking 
such action not inconsistent with this Trust Agreement as it shall deem 
advisable and in the best interests of the Securityholders, in which event 
the Property Trustee shall have no liability except for its own bad faith, 
negligence or willful misconduct; 

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

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

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

          (f)     the Property Trustee may consult with counsel (which 
counsel may be counsel to the Depositor or any of its Affiliates, and may 
include any of its employees) and the advice of such counsel shall be full 
and complete authorization and protection in respect of any action taken, 
suffered or omitted by it hereunder in good faith and in reliance thereon and 
in accordance with such advice, such counsel may be counsel to the Depositor 
or any of its Affiliates, and 

                                     38


may include any of its employees; the Property Trustee shall have the right 
at any time to seek instructions concerning the administration of this Trust 
Agreement from any court of competent jurisdiction; 

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

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

          (i) the Property Trustee may execute any of the trusts or powers 
hereunder or perform any duties hereunder either directly or by or through 
its agents or attorneys, provided that the Property Trustee shall be 
responsible for its own negligence or recklessness with respect to selection 
of any agent or attorney appointed by it hereunder; 
     
          (j) whenever in the administration of this Trust Agreement the 
Property Trustee shall deem it desirable to receive instructions with respect 
to enforcing any remedy or right or taking any other action hereunder the 
Property Trustee (i) may request instructions from the Holders of the Trust 
Securities which instructions may only be given by the Holders of the same 
proportion in Liquidation Amount of the Trust Securities as would be entitled 
to direct the Property Trustee under the terms of the Trust Securities in 
respect of such remedy, right or action, (ii) may refrain from enforcing such 
remedy or right or taking such other action until such instructions are 
received, and (iii) shall be protected in acting in accordance with such 
instructions; and 

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

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

                                      39



to exercise any such right, power, duty or obligation. No permissive power or 
authority available to the Property Trustee shall be construed to be a duty. 

     Section 8.4 NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.  The 
recitals contained herein and in the Trust Securities Certificates shall be 
taken as the statements of the Trust, and the Trustees do not assume any 
responsibility for their correctness. The Trustees shall not be accountable 
for the use or application by the Depositor of the proceeds of the 
Debentures. 

     Section 8.5 MAY HOLD SECURITIES.  Except as provided in the definition 
of the term "Outstanding" in Article I, any Trustee or any other agent of any 
Trustee or the Trust, in its individual or any other capacity, may become the 
owner or pledgee of Trust Securities and, subject to Sections 8.8 and 8.13, 
may otherwise deal with the Trust with the same rights it would have if it 
were not a Trustee or such other agent. 

     Section 8.6 COMPENSATION; INDEMNITY; FEES.  The Depositor agrees: 

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

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

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

                                      40



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

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

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

     Section 8.7 CORPORATE PROPERTY TRUSTEE REQUIRED; ELIGIBILITY OF TRUSTEES.

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

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

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

                                       41



otherwise meets the requirements of applicable Delaware law that shall act 
through one or more persons authorized to bind such entity. 

     Section 8.8 CONFLICTING INTERESTS.  If the Property Trustee has or shall 
acquire a conflicting interest within the meaning of the Trust Indenture Act, 
the Property Trustee shall either eliminate such interest or resign, to the 
extent and in the manner provided by, and subject to the provisions of, the 
Trust Indenture Act and this Trust Agreement. 

     Section 8.9 CO-TRUSTEES AND SEPARATE TRUSTEE.  Unless an Event of 
Default shall have occurred and be continuing, at any time or times, for the 
purpose of meeting the legal requirements of the Trust Indenture Act or of 
any jurisdiction in which any part of the Trust Property may at the time be 
located, the Depositor and the Administrative Trustees, by agreed action of 
the majority of such Trustees, shall have power to appoint, and upon the 
written request of the Administrative Trustees, the Depositor shall for such 
purpose join with the Administrative Trustees 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.  If the Depositor 
does not join in such appointment within 15 days after the receipt by it of a 
request so to do, or in case a Debenture Event of Default has occurred and is 
continuing, the Property Trustee alone shall have power to make such 
appointment.  Any co-trustee or separate trustee appointed pursuant to this 
Section shall either be (i) a natural person who is at least 21 years of age 
and a resident of the United States or (ii) a legal entity with its principal 
place of business in the United States that shall act through one or more 
persons authorized to bind such entity. 

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

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

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

                                      42



or pledged with, the Trustees specified hereunder shall be exercised solely 
by such Trustees and not by such co-trustee or separate trustee. 

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

          (c) The Property Trustee at any time, by an instrument in writing 
executed by it, with the written concurrence of the Depositor, may accept the 
resignation of or remove any co-trustee or separate trustee appointed under 
this Section, and, in case a Debenture Event of Default has occurred and is 
continuing, the Property Trustee shall have power to accept the resignation 
of, or remove, any such co-trustee or separate trustee without the 
concurrence of the Depositor. Upon the written request of the Property 
Trustee, the Depositor shall join with the Property Trustee in the execution, 
delivery and performance of all instruments and agreements necessary or 
proper to effectuate such resignation or removal.  A successor to any 
co-trustee or separate trustee so resigned or removed may be appointed in the 
manner provided in this Section. 

          (d) No co-trustee or separate trustee hereunder shall be personally 
liable by reason of any act or omission of the Property Trustee or any other 
trustee hereunder. 

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

          (f) Any Act of Holders delivered to the Property Trustee shall be 
deemed to have been delivered to each such co-trustee and separate trustee. 

     Section 8.10 RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.  No 
resignation or removal of any Trustee (the "Relevant Trustee") and no 
appointment of a successor Trustee pursuant to this Article shall become 
effective until the acceptance of appointment by the successor Trustee in 
accordance with the applicable requirements of Section 8.11. 

     Subject to the immediately preceding paragraph, the Relevant Trustee may 
resign at any time by giving written notice thereof to the Securityholders.  
If the instrument of acceptance by the successor Trustee required by Section 
8.11 shall not have been delivered to the Relevant Trustee within 30 days 
after the giving of 

                                      43



such notice of resignation, the Relevant Trustee may petition, at the expense 
of the Trust, any court of competent jurisdiction for the appointment of a 
successor Relevant Trustee. 

     Unless a Debenture Event of Default shall have occurred and be 
continuing, any Trustee may be removed at any time by Act of the Common 
Securityholder.  If a Debenture Event of Default shall have occurred and be 
continuing, the Property Trustee or the Delaware Trustee, or both of them, 
may be removed at such time by Act of the Holders of a majority in 
Liquidation Amount of the Preferred Securities, delivered to the Relevant 
Trustee (in its individual capacity and on behalf of the Trust).  In no event 
will the Holders of the Preferred Securities have the right to vote to 
appoint, remove or replace the Administrative Trustee. An Administrative 
Trustee may be removed by the Common Securityholder at any time. 

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

     The Property Trustee shall give notice of each resignation and each 
removal of a Trustee and each appointment of a successor Trustee to all 
Securityholders in the manner provided in Section 10.8 and shall give notice 
to 

                                      44



the Depositor. Each notice shall include the name of the successor Relevant 
Trustee and the address of its Corporate Trust Office if it is the Property 
Trustee. 

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

     Section 8.11 ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.  In case of the 
appointment hereunder of a successor Trustee such successor Trustee so 
appointed shall execute, acknowledge and deliver to the Trust and to the 
retiring Trustee an instrument accepting such appointment, and thereupon the 
resignation or removal of the retiring Trustee shall become effective and 
such successor Trustee, without any further act, deed or conveyance, shall 
become vested with all the rights, powers, trusts and duties of the retiring 
Trustee; but, on the request of the Depositor or the successor Trustee, such 
retiring Trustee shall, upon payment of its charges, execute and deliver an 
instrument transferring to such successor Trustee all the rights, powers and 
trusts of the retiring Trustee and if the Property Trustee is the resigning 
Trustee shall duly assign, transfer and deliver to the successor Trustee all 
property and money held by such retiring Property Trustee hereunder. 

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

                                      45



proceeds thereof and money held by such retiring Relevant Trustee hereunder 
with respect to the Trust Securities and the Trust. 

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

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

     Section 8.12 MERGER, CONVERSION, CONSOLIDATION OR SUCCESSIONS 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 
corporation resulting from any merger, conversion or consolidation to which 
such Relevant Trustee shall be a party, or any corporation succeeding to all 
or substantially all the corporate trust business of such Relevant Trustee,

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

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

          (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 

                                      46



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.

Securities.

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

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

or if the number of Trustees is increased pursuant to Section 8.17(a), a 
vacancy shall occur.  The vacancy shall be filled with a Trustee appointed in 
accordance with Section 8.10. 

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

operate to annul the Trust.  Whenever a vacancy in the number of 
Administrative Trustees shall occur, until such vacancy is filled by the 
appointment of an Administrative Trustee in accordance with Section 8.10, the 
Administrative Trustees in office, regardless of their number (and 
notwithstanding any other provision of this Agreement), shall have all the 
powers granted to the Administrative Trustees and shall discharge all the 
duties imposed upon the Administrative Trustees by this Trust Agreement. 

     Section 8.18 DELEGATION OF POWER.

          (a) Any Administrative Trustee may, by power of attorney consistent

Agreement, as set forth herein.

                       TERMINATION, LIQUIDATION AND MERGER

     Section 9.1 TERMINATION UPON EXPIRATION DATE.  Unless terminated 
earlier, the Trust shall automatically terminate on December 31, 2___ (the 
"Expiration Date"), following the distribution of the Trust Property in 
accordance with Section 9.4. 

     Section 9.2 EARLY TERMINATION.  The first to occur of any of the 
following events is an "Early Termination Event": 

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

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

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

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

     Section 9.3 TERMINATION.  The respective obligations and 
responsibilities of the Trustees and the Trust created and continued hereby 
shall terminate upon the latest to occur of the following: (a) the 
distribution by the Property Trustee to Securityholders upon the liquidation 
of the Trust pursuant to Section 9.4, or upon the redemption of all of the 
Trust Securities pursuant to Section 4.2, of all amounts required to be 
distributed hereunder upon the final payment of the Trust Securities; (b) the 
payment of any expenses owed by the Trust; (c) the discharge of all 
administrative duties of the Administrative Trustees, including the 
performance of any tax reporting obligations with respect to the Trust or the 

                                      49



Securityholders; and (d) the filing of a Certificate of Cancellation by the 
Administrative Trustee under the Business Trust Act. 

     Section 9.4 LIQUIDATION.

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

              (i) state the Liquidation Date; 

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

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

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

          (c) Except where Section 9.2(c) or 9.4(d) applies, after the 
Liquidation Date, (i) the Trust Securities will no longer be deemed to be 
Outstanding, (ii) certificates representing a Like Amount of Debentures will 
be issued to holders of Trust Securities Certificates, upon surrender of such 
certificates to the Administrative Trustees or their agent for exchange, 
(iii) the Depositor shall use its best efforts to have the Debentures listed 
on the New York Stock Exchange or on such other exchange, interdealer 
quotation system or self-regulatory organization as the Preferred Securities 
are then listed, (iv) any Trust 

                                      50



Securities Certificates not so surrendered for exchange will be deemed to 
represent a Like Amount of Debentures, accruing interest at the rate provided 
for in the Debentures from the last Distribution Date on which a Distribution 
was made on 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 Debentures represented by 
such certificates) and (v) all rights of Securityholders holding Trust 
Securities will cease, except the right of such Securityholders to receive a 
Like Amount of Debentures upon surrender of Trust Securities Certificates. 

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

     Section 9.5 MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF 
THE TRUST.  The Trust may not merge with or into, consolidate, amalgamate, or 
be replaced by, or convey, transfer or lease its properties and assets 
substantially as an entirety to any corporation or other body, except 
pursuant to this Section 9.5.  At the request of the Depositor, with the 
consent of the Administrative Trustees and without the consent of the Holders 
of the Preferred Securities, the Property Trustee or the Delaware Trustee, 
the Trust may merge with or into, consolidate, amalgamate, or be replaced by 
or convey, transfer or lease its properties and assets substantially as an 
entirety to a trust organized as such under the laws of any State; provided, 
that (i) such successor entity either (a) expressly assumes all of the 
obligations of the Trust with respect to the Preferred Securities or (b) 
substitutes for the Preferred Securities other securities having 
substantially the same terms as the Preferred Securities (the "Successor 
Securities") so long as the

                                      51



Successor Securities rank the same as the Preferred Securities rank in 
priority with respect to distributions and payments upon liquidation, 
redemption and otherwise, (ii) the Depositor expressly appoints a trustee of 
such successor entity possessing the same powers and duties as the Property 
Trustee as the holder of the Debentures, (iii) the Successor Securities are 
listed or traded, or any Successor Securities will be listed upon 
notification of issuance, on any national securities exchange or other 
organization on which the Preferred Securities are then listed or traded, if 
any, (iv) such merger, consolidation, amalgamation, replacement, conveyance, 
transfer or lease does not cause the Preferred Securities (including any 
Successor Securities) to be downgraded by any nationally recognized 
statistical rating organization, (v) such merger, consolidation, 
amalgamation, replacement, conveyance, transfer or lease does not adversely 
affect the rights, preferences and privileges of the holders of the Preferred 
Securities (including any Successor Securities) in any material respect, (vi) 
such successor entity has a purpose identical to that of the Trust, (vii) 
prior to such merger, consolidation, amalgamation, replacement, conveyance, 
transfer or lease, the Depositor has received an Opinion of Counsel to the 
effect that (a) such merger, consolidation, amalgamation, replacement, 
conveyance, transfer or lease does not adversely affect the rights, 
preferences and privileges of the holders of the Preferred Securities 
(including any Successor Securities) in any material respect, and (b) 
following such merger, consolidation, amalgamation, replacement, conveyance, 
transfer or lease, neither the Trust nor such successor entity will be 
required to register as an investment company under the 1940 Act and (viii) 
the Depositor owns all of the Common Securities of such successor entity and 
guarantees the obligations of such successor entity under the Successor 
Securities at least to the extent provided by the Guarantee. Notwithstanding 
the foregoing, the Trust shall not, except with the consent of holders of 
100% in Liquidation Amount of the Preferred Securities, consolidate, 
amalgamate, merge with or into, or be replaced by or convey, transfer or 
lease its properties and assets substantially as an entirety to any other 
entity or permit any other entity to consolidate, amalgamate, merge with or 
into, or replace it if such consolidation, amalgamation, merger, replacement, 
conveyance, transfer or lease would cause the Trust or the successor entity 
to be classified as other than a grantor trust for United States Federal 
income tax purposes.  See Prospectus description.

                            MISCELLANEOUS PROVISIONS

     Section 10.1 LIMITATION OF RIGHTS OF SECURITYHOLDERS.  The death or 
incapacity of any person having an interest, beneficial or otherwise, in 
Trust Securities shall not operate to terminate this Trust Agreement, nor 
entitle the legal representatives or heirs of such person or any 
Securityholder for such person, to claim an accounting, take any action or 
bring any proceeding in any court for a partition or winding up of the 
arrangements contemplated hereby, nor otherwise affect the rights, 
obligations and liabilities of the parties hereto or any of them.

questions arising under this Trust Agreement, which shall not be inconsistent 
with the other provisions of this Trust Agreement, or (ii) to modify,

required to register as an investment company under the 1940 Act; provided, 
however, that in the case of clause (i), such action shall not adversely

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

          (c) In addition to and notwithstanding any other provision in this 
Trust Agreement, without the consent of each affected Securityholder (such

institute suit for the enforcement of any such payment on or after such date; 
notwithstanding any other provision herein, without the unanimous consent of 
the Securityholders (such consent being obtained in accordance with Section

amended. 

          (d) Notwithstanding any other provisions of this Trust Agreement, 
no Trustee shall enter into or consent to any amendment to this Trust 
Agreement which would cause the Trust to fail or cease to qualify for the 
exemption from status of an investment company under the 1940 Act or fail or 
cease to be classified as a grantor trust for United States Federal income 
tax purposes. 

                                      53

made, the Administrative Trustees shall promptly provide to the Depositor a 
copy of such amendment. 

          (g) Neither the Property Trustee nor the Delaware Trustee shall be

Property Trustee shall be entitled to receive an Opinion of Counsel and an 
Officers' Certificate stating that any amendment to this Trust Agreement is 
in compliance with this Trust Agreement. 

     Section 10.3 SEPARABILITY.  In case any provision in this Trust

Agreement as so modified or excluded, as the case may be.

The Depository Trust Company,

New York, New York 10041-0099 

____________, 1997 

Attention: 
General Counsel's Office 

Re:   FIB Capital Trust ___% Cumulative Trust Preferred Securities 

Ladies and Gentlemen: 

   The purpose of this letter is to set forth certain matters relating to the 
issuance and deposit with The Depository Trust Company ("DTC") of the FIB 
Capital Trust ___% Cumulative Trust Preferred Securities, (the "Trust 
Preferred Securities"), of FIB Capital Trust, a Delaware business trust (the 
"Issuer"), formed pursuant to an Amended and Restated Trust Agreement between 
First Interstate BancSystem, Inc. ("First Interstate BancSystem"), and 
Wilmington Trust Company, as Property Trustee, Wilmington Trust Company, as 
Delaware Trustee, and the Administrative Trustees named therein. The payment 
of distributions on the Trust Preferred Securities, and payments due upon 
liquidation of the Issuer or redemption of the Trust Preferred Securities, to 
the extent the Issuer has funds available for the payment thereof are 
guaranteed by First Interstate BancSystem to the extent set forth in a 
Guarantee Agreement dated ________, 1997, by First Interstate BancSystem and 
Wilmington Trust Company, as guarantee trustee, with respect to the Trust 
Preferred Securities.  First Interstate BancSystem and the Issuer propose to 
sell the Trust Preferred Securities to certain Underwriter(s) (the 
"Underwriter(s)") pursuant to an Underwriting Agreement dated __________, 
1997 by and among the Underwriter(s), the Issuer and Depositor and the 
Underwriter(s) wish to take delivery of the Trust Preferred Securities 
through DTC.  Wilmington Trust Company is acting as transfer agent and 
registrar with respect to the Trust Preferred Securities (the "Transfer Agent 
and Registrar"). 

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

   1. Prior to the closing of the sale of the Trust Preferred Securities to 
the Underwriter(s), which is expected to occur on or about __________, 1997, 


                                     60



there shall be deposited with DTC one or more global certificates 
(individually and collectively, the "Global Certificate") registered in the 
name of DTC's Trust Preferred Securities nominee, ________, representing an 
aggregate of  Trust Preferred 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 the Issuer or its agent for 
      registration of transfer, exchange, or payment, and any 
      certificate issued is registered in the name of _________ or in 
      such other name as is requested by an authorized representative 
      of DTC (and any payment is made to _________ 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, ______, has an interest herein.

   2. The Amended and Restated Trust Agreement of the Issuer provides for the 
voting by holders of the Trust Preferred 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. 

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

   4. In the event of distribution on, or an offering or issuance of rights 
with respect to, the Trust Preferred 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 Trust Preferred Securities is required; and (c) the date any 
required notice is to be mailed by or on behalf of the Issuer to holders of 
Trust Preferred Securities or published by or on behalf of the Issuer 
(whether by mail or publication, the "Publication Date").  Such notice shall 
be sent to DTC by a secure means (e.g., legible telecopy, registered or 
certified mail, overnight delivery) in a timely manner designed to assure 
that such notice is in DTC's possession no later than the close of business 
on the business day before the Publication Date.  The Issuer or the Transfer 
Agent and Registrar will forward such notice either in a separate secure 
transmission for 


                                      61



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 Trust Preferred 
Securities.  After establishing the amount of payment to be made on the Trust 
Preferred Securities, the Issuer or the Transfer Agent and Registrar will 
notify DTC's Dividend Department of such payment five business days prior to 
payment date.  Notices to DTC's Dividend Department by telecopy shall be sent

Securities, notice specifying the terms of the redemption and the Publication

   6. In the event of any invitation to tender the Trust Preferred 
Securities, notice specifying the terms of the tender and the Publication

designation of the Trust Preferred Securities, which, as of the date of this 
letter, is "FIB Capital Trust ___% Cumulative Trust Preferred Securities."

   8. Distribution payments or other cash payments with respect to the Trust

made payable to the order of _______, and shall be addressed as follows:

                         New York, New York 10004-2695

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

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

   11. DTC may discontinue its services as a securities depository with 
respect to the Trust Preferred Securities at any time by giving at least 90 
days' prior written notice to the Issuer and the Transfer Agent and Registrar 
(at which time DTC will confirm with the Issuer or the Transfer Agent and 
Registrar the aggregate number of Trust Preferred Securities deposited with 
it) and discharging its responsibilities with respect thereto under 
applicable law. Under such circumstances, the Issuer may determine to make 
alternative arrangements for


                                      63



book-entry settlement for the Trust Preferred Securities, make available one 
or more separate global certificates evidencing Trust Preferred Securities to 
any Participant having Trust Preferred Securities credited to its DTC 
account, or issue definitive Trust Preferred Securities to the beneficial 
holders thereof, and in any such case, DTC agrees to cooperate fully with the 
Issuer and the Transfer Agent and Registrar, and to return the Global 
Certificate, duly endorsed for transfer as directed by the Issuer or the 
Transfer Agent and Registrar, together with any other documents of transfer 
reasonably requested by the Issuer or the Transfer Agent and Registrar. 

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

   13. This letter may be executed in any number of counterparts, each of 
which when so executed shall be deemed to be an original, but all such 
counterparts shall together constitute but one and the same instrument.  
Nothing herein shall be deemed to require the Transfer Agent and Registrar to 
advance funds on behalf of FIB Capital Trust. 

                                       Very truly yours,
