Trustee of the Series A Issuer. The Series A Issuer exists for the sole purpose
of issuing the Series A QUIPS and the Series A Common Securities and investing
the proceeds thereof in $       aggregate principal amount of      % Junior
Subordinated Deferrable Interest Debentures, Series A (the "Series A
Subordinated Debentures"), to be issued by the Corporation. The Series A
Subordinated Debentures will mature on                , 2026, which date may be
(i) shortened to a date not earlier than           , 2001 or (ii) extended to a
date not later than                , 2045, in either case if certain conditions
are met. The Corporation has committed to the Federal Reserve Bank of St. Louis
(the "Reserve Bank") that the Corporation will not shorten the Stated Maturity
(as defined herein) without having received the prior approval of the Board of
Governors of the Federal Reserve System (the "Federal Reserve") to do so, if
then required under applicable Federal Reserve capital guidelines or policies.
The Series A QUIPS will have a preference under certain circumstances with
respect to cash distributions and amounts payable on liquidation or redemption
over the Series A Common Securities. See "Description of Preferred Securities --
Subordination of Common Securities" in the accompanying Prospectus.
    
 
     Holders of the Series A QUIPS will be entitled to receive preferential
cumulative cash distributions accruing from the date of original issuance and
payable quarterly in arrears on the last day of March, June, September and
December of each year, commencing March 31, 1997, at the annual rate of      %
of the Liquidation Amount (as defined in the accompanying Prospectus) of $25 per
Series A QUIPS ("Distributions"). Subject to certain exceptions, as described
herein, the Corporation has the right to defer payment of interest on the Series
A Subordinated Debentures at any time or from time to time for a period not
exceeding 20 consecutive quarters with respect to each deferral period (each, an
"Extension Period"), provided that no Extension Period may extend beyond the
Stated Maturity of the Series A Subordinated Debentures. Upon the termination of
any such Extension Period and the payment of all interest then accrued and
unpaid (together with interest thereon at the rate of        %, compounded
quarterly, to the extent permitted by applicable law), the Corporation may elect
to begin a new Extension Period subject to the requirements set forth herein. If
interest payments on the Series A Subordinated Debentures are so deferred,
Distributions on the Series A QUIPS will also be deferred and the Corporation
will not be permitted, subject to certain exceptions described herein, to
declare or pay any cash distributions with respect to the Corporation's capital
stock or debt securities that rank pari passu with or junior to the Series A
Subordinated Debentures. During an Extension Period, interest on the Series A
Subordinated Debentures will continue to accrue (and the amount of Distributions
to which holders of the Series A QUIPS are entitled will accumulate) at the rate
of      % per annum, compounded quarterly from the relevant payment date for
such interest, and holders of Series A QUIPS will be required to accrue interest
income for United States federal income tax purposes. See "Certain Terms of
Series A Subordinated Debentures -- Option to Defer Interest Payments" and
"Certain Federal Income Tax Consequences -- Interest Income and Original Issue
Discount".
 
     The Series A Subordinated Debentures are unsecured and subordinated to all
Senior Indebtedness (as defined in the accompanying Prospectus). At September
30, 1996, the aggregate amount of Senior Indebtedness outstanding was
approximately $160 million. Because the Corporation is a holding company, the
right of the Corporation to participate in any distribution of assets of any
subsidiary, including First Tennessee Bank National Association, upon such
subsidiary's liquidation or reorganization or otherwise, is subject to the prior
claims of creditors of that subsidiary, except to the extent that the
Corporation may itself be recognized as a creditor of that subsidiary.
Accordingly,

the Series A Subordinated Debentures (and therefore the Series A QUIPS) will be
effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and holders thereof should look only to the assets
of the Corporation for payments on the Series A Subordinated Debentures. See
"Description of Subordinated Debentures -- Subordination" in the accompanying
Prospectus.
 
   
     The Corporation has, through the Series A Guarantee, the Trust Agreement,
the Series A Subordinated Debentures and the Indenture (each as defined herein),
taken together, fully, irrevocably and unconditionally guaranteed all of the
Series A Issuer's obligations under the Series A QUIPS. See "Relationship Among
the Preferred Securities, the Corresponding Junior Subordinated Debentures and
the Guarantees -- Full and Unconditional Guarantee" in the accompanying
Prospectus. The Series A Guarantee of the Corporation guarantees the payment of
Distributions and payments on liquidation or redemption of the Series A QUIPS,
but only in each case to the extent of funds held by the Series A Issuer, as
described herein (the "Series A Guarantee"). See "Description of Guarantees" in
the accompanying Prospectus. If the Corporation does not make interest payments
on the Series A Subordinated Debentures held by the Series A Issuer, the Series
A Issuer will have insufficient funds to pay Distributions on the Series A
QUIPS. The Series A Guarantee does not cover payment of Distributions when the
Series A Issuer has insufficient funds to pay such Distributions. In such event,
a holder of Series A QUIPS may institute a legal proceeding directly against the
Corporation pursuant to the terms of the Indenture to enforce payment of amounts
equal to such Distributions to such holder. See "Description of Junior
Subordinated Debentures -- Enforcement of Certain Rights By Holders of Preferred
Securities" in the accompanying Prospectus. The obligations of the Corporation
under the Series A Guarantee are subordinate and junior in right of payment to
all Senior Indebtedness of the Corporation.
    
 
   
     The Series A QUIPS are subject to mandatory redemption, in whole or in
part, upon repayment of Series A Subordinated Debentures at maturity or their
earlier redemption. The Series A Subordinated Debentures are redeemable prior to
maturity at the option of the Corporation (i) on or after                , 2001,
in whole at any time or in part from time to time, or (ii) at any time, in whole
(but not in part), upon the occurrence and continuation of a Tax Event or a
Capital Treatment Event (each as defined herein). In any case the redemption
price for the Series A QUIPS will be the aggregate Liquidation Amount of such
Series A QUIPS plus accumulated and unpaid Distributions thereon to the date of
redemption. The Corporation has committed to the Reserve Bank that it will not
cause any such redemption without having received the prior approval of the
Federal Reserve to do so, if then required under applicable Federal Reserve
capital guidelines or policies. See "Certain Terms of Series A QUIPS --
Redemption" and "Certain Terms of Series A Subordinated
Debentures -- Redemption".
    
 
     The Corporation will have the right at any time to terminate the Series A
Issuer, subject to the Corporation having received prior approval of the Federal
Reserve to do so if then required under applicable capital guidelines or
policies. See "Certain Terms of Series A QUIPS -- Liquidation of Series A Issuer
and Distribution of Series A Subordinated Debentures to Holders". In the event
of the termination of the Series A Issuer, after satisfaction of liabilities to
creditors of the Series A Issuer as required by applicable law, the holders of
the Series A QUIPS will be entitled to receive a Liquidation Amount of $25 per
Series A QUIPS plus accumulated and unpaid Distributions thereon to the date of
payment, which may be in the form of a distribution of such amount in Series A
Subordinated Debentures in exchange therefor, subject to certain exceptions. See
"Description of Preferred Securities -- Liquidation Distribution Upon
Termination" in the accompanying Prospectus.
 
     Application will be made to have the Series A QUIPS approved for quotation
on the NASDAQ National Market under the symbol "       ". If Series A
Subordinated Debentures are distributed to the holders of Series A QUIPS in
exchange therefor upon the liquidation of the Series A Issuer, the Corporation
will use its best efforts to have the Series A Subordinated Debentures approved
for

quotation on the NASDAQ National Market or such stock exchanges or other
automated quotation systems, if any, on which the Series A QUIPS are then listed
or traded.
 
     The Series A QUIPS will be represented by global certificates registered in
the name of The Depository Trust Company ("DTC") or its nominee. Beneficial
interests in the Series A QUIPS will be shown on, and transfers thereof will be
effected only through, records maintained by participants in DTC. Except as
described in the accompanying Prospectus, Series A QUIPS in certificated form
will not be issued in exchange for the global certificates. See "Certain Terms
of Series A QUIPS -- Registration of Series A QUIPS".

                                  RISK FACTORS
 
     Prospective purchasers of the Series A QUIPS should carefully review the
information contained elsewhere in this Prospectus Supplement and in the
accompanying Prospectus and should particularly consider the following matters.
In addition, because holders of Series A QUIPS may receive Series A Subordinated
Debentures in exchange therefor upon liquidation of the Series A Issuer,
prospective purchasers of Series A QUIPS are also making an investment decision
with regard to the Series A Subordinated Debentures and should carefully review
all the information regarding the Series A Subordinated Debentures contained
herein.
 
RANKING OF SUBORDINATED OBLIGATIONS UNDER THE SERIES A GUARANTEE AND THE SERIES
A SUBORDINATED DEBENTURES
 
   
     The obligations of the Corporation under the Series A Guarantee issued by
the Corporation for the benefit of the holders of Series A Securities and under
the Series A Subordinated Debentures are unsecured and rank subordinate and
junior in right of payment to all Senior Indebtedness of the Corporation. At
September 30, 1996, the aggregate amount of Senior Indebtedness of the
Corporation outstanding was approximately $160 million. Because the Corporation
is a holding company, the right of the Corporation to participate in any
distribution of the assets of any subsidiary, including First Tennessee Bank
National Association, upon such subsidiary's liquidation or reorganization or
otherwise, is subject to the prior claims of creditors of that subsidiary,
except to the extent that the Corporation may itself be recognized as a creditor
of that subsidiary. Accordingly, the Series A Subordinated Debentures will be
effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and holders of Series A Subordinated Debentures
should look only to the assets of the Corporation for payments on the Series A
Subordinated Debentures. See "First Tennessee National Corporation". None of the
Indenture, the Series A Guarantee or the Trust Agreement places any limitation
on the amount of secured or unsecured debt, including Senior Indebtedness, that
may be incurred by the Corporation. See "Description of Guarantees -- Status of
the Guarantees" and "Description of Junior Subordinated
Debentures -- Subordination" in the accompanying Prospectus.
    
 
     The ability of the Series A Issuer to pay amounts due on the Series A QUIPS
is solely dependent upon the Corporation making payments on the Series A
Subordinated Debentures as and when required.
 
OPTION TO DEFER INTEREST PAYMENT; TAX CONSEQUENCES; MARKET PRICE CONSEQUENCES
 
     So long as no event of default under the Indenture has occurred or is
continuing, the Corporation has the right under the Indenture to defer payment
of interest on the Series A Subordinated Debentures at any time or from time to
time for a period not exceeding 20 consecutive quarters with respect to each
Extension Period, provided that no Extension Period may extend beyond the Stated
Maturity of the Series A Subordinated Debentures. As a consequence of any such
deferral, quarterly Distributions on the Series A QUIPS by the Series A Issuer
will also be deferred (and the amount of Distributions to which holders of the
Series A QUIPS are entitled will accumulate additional Distributions thereon at
the rate of      % per annum, compounded quarterly from the relevant payment
date for such Distributions) during any such Extension Period. During any such
Extension Period, the Corporation may not, and may not permit any subsidiary of
the Corporation to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of
the Corporation's capital stock, (ii) make any payment of principal, interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Corporation (including other series of Junior Subordinated Debentures) that rank
pari passu with or junior in interest to the Series A Subordinated Debentures or
(iii) make any guarantee payments with respect to any guarantee by the
Corporation of the debt securities of any subsidiary of the Corporation if such
guarantee ranks pari passu with or junior in interest to the Series A
Subordinated Debentures (other than (a) dividends or distributions in capital
stock of the
 
                                       S-6
<PAGE>   8
 
Corporation, (b) any declaration of a dividend in connection with the
implementation of a stockholders' rights plan or the redemption or repurchase of
any such rights pursuant thereto, (c) payments under the Series A Guarantee and
(d) purchases of common stock related to the issuance of common stock or rights
or options under any of the Corporation's benefit plans for its directors,
officers, employees or other persons within the definition of "employee" for
purposes of a registration of shares for an employee benefit plan of the
Corporation, related to the issuance of common stock or rights under a dividend
reinvestment and stock purchase plan, or related to the issuance of common stock
(or securities convertible into or exchangeable for common stock) as
consideration in an acquisition transaction). Prior to the termination of any
such Extension Period, the Corporation may further defer the payment of
interest, provided that no Extension Period may exceed 20 consecutive quarters
or extend beyond the Stated Maturity of the Series A Subordinated Debentures.
Upon the termination of any Extension Period and the payment of all interest
then accrued and unpaid (together with interest thereon at the annual rate of
  %, compounded quarterly from the interest payment date for such interest, to
the extent permitted by applicable law), the Corporation may elect to begin a
new Extension Period subject to the above requirements. There is no limitation
on the number of times that the Corporation may elect to begin an Extension
Period. See "Certain Terms of Series A QUIPS -- Distributions" and "Certain
Terms of Series A Subordinated Debentures -- Option to Defer Interest Payments".
 
     Should an Extension Period occur, a holder of Series A QUIPS will be
required to accrue income (in the form of original issue discount) in respect of
its pro rata share of the Series A Subordinated Debentures held by the Series A
Issuer for United States federal income tax purposes. As a result, a holder of
Series A QUIPS will be required to include such income in gross income for
United States federal income tax purposes in advance of the receipt of cash
attributable to such income, and will not receive the cash related to such
income from the Series A Issuer if the holder disposes of the Series A QUIPS
prior to the record date for the payment of Distributions. See "Certain Federal
Income Tax Consequences -- Interest Income and Original Issue Discount" and
"-- Sales or Redemption of Series A QUIPS".
 
     The Corporation has no current intention of exercising its right to defer
payments of interest on the Series A Subordinated Debentures. However, should
the Corporation elect to exercise such right in the future, the market price of
the Series A QUIPS is likely to be affected. A holder that disposes of its
Series A QUIPS during an Extension Period, therefore, might not receive the same
return on its investment as a holder that continues to hold its Series A QUIPS.
 
TAX EVENT OR CAPITAL TREATMENT EVENT -- REDEMPTION
 
   
     Upon the occurrence and continuation of a Tax Event or Capital Treatment
Event (whether occurring before or after             , 2001), the Corporation
has the right to redeem the Series A Subordinated Debentures in whole (but not
in part) within 90 days following the occurrence of such Tax Event or Capital
Treatment Event and thereby cause a mandatory redemption of the Series A QUIPS.
The Corporation has committed to the Reserve Bank that it will not cause any
such redemption without having received the prior approval of the Federal
Reserve to do so, if then required under applicable Federal Reserve capital
guidelines or policies.
    
 
   
     A "Tax Event" means, with respect to Series A Subordinated Debentures held
by the Series A Issuer or another Issuer (as defined in the Prospectus), the
receipt by the Series A Issuer of an opinion of counsel experienced in such
matters to the effect that, as a result of any amendment to, or change
(including any announced proposed change) in, the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein, or as a result of any official administrative
pronouncement or judicial decision interpreting or applying such laws or
regulations, which amendment or change is effective or such proposed change,
pronouncement or decision is announced on or after the date of issuance of the
Series A QUIPS under the Trust Agreement, there is more than an insubstantial
risk that (i) the Series A Issuer is, or will be within 90 days of the date of
such opinion, subject to United States federal income tax with respect
    
 
                                       S-7
<PAGE>   9
 
   
to income received or accrued on the Series A Subordinated Debentures, (ii)
interest payable by the Corporation on the Series A Subordinated Debentures is
not, or within 90 days of the date of such opinion, will not be, deductible by
the Corporation, in whole or in part, for United States federal income tax
purposes or (iii) the Series A Issuer is, or will be within 90 days of the date
of the opinion, subject to more than a de minimis amount of other taxes, duties
or other governmental charges. With respect to Series A Subordinated Debentures
which are no longer held by the Series A Issuer or another Issuer, "Tax Event"
means the receipt by the Corporation of an opinion of counsel experienced in
such matters to the effect that, as a result of any amendment to, or change
(including any announced proposed change) in, the laws (or any regulations
thereunder) of the United States or any political subdivision or taxing
authority thereof or therein, or as a result of any official administrative
pronouncement or judicial decision interpreting or applying such laws or
regulations, which amendment or change is effective or which proposed change,
pronouncement or decision is announced on or after the date of issuance of the
Series A Subordinated Debentures under the Indenture, there is more than an
insubstantial risk that interest payable by the Corporation on the Series A
Subordinated Debentures is not, or within 90 days of the date of such opinion
will not be, deductible by the Corporation, in whole or in part, for United
States federal income tax purposes.
    
 
   
     See " -- Possible Tax Law Changes Affecting the Series A QUIPS" for a
discussion of certain legislative proposals that, if adopted, could give rise to
a Tax Event, which may permit the Corporation to cause a redemption of the
Series A QUIPS prior to             , 2001.
    
 
     A "Capital Treatment Event" means the reasonable determination by the
Corporation that, as a result of any amendment to, or change (including any
proposed change) in, the laws (or any regulations thereunder) of the United
States or any political subdivision thereof or therein, or as a result of any
official or administrative pronouncement or action or judicial decision
interpreting or applying such laws or regulations, which amendment or change is
effective or such proposed change, pronouncement, action or decision is
announced on or after the date of issuance of the Series A QUIPS under the Trust
Agreement, there is more than an insubstantial risk that the Corporation will
not be entitled to treat an amount equal to the Liquidation Amount of the Series
A QUIPS as "Tier 1 Capital" (or the then equivalent thereof) for purposes of the
capital adequacy guidelines of the Federal Reserve, as then in effect and
applicable to the Corporation.
 
   
EXCHANGE OF SERIES A QUIPS FOR SERIES A SUBORDINATED DEBENTURES
    
 
     The Corporation will have the right at any time to terminate the Series A
Issuer and, after satisfaction of liabilities to creditors of the Series A
Issuer as required by applicable law, cause the Series A Subordinated Debentures
to be distributed to the holders of the Series A QUIPS in exchange therefor upon
liquidation of the Series A Issuer. The exercise of such right is subject to the
Corporation having received prior approval of the Federal Reserve if then
required under applicable capital guidelines or policies. See "Certain Terms of
Series A QUIPS -- Liquidation of Series A Issuer and Distribution of Series A
Subordinated Debentures to Holders".
 
     Under current United States federal income tax law and interpretations, a
distribution of the Series A Subordinated Debentures upon a liquidation of the
Series A Issuer should not be a taxable event to holders of the Series A QUIPS.
However, if a Tax Event were to occur which would cause the Series A Issuer to
be subject to United States federal income tax with respect to income received
or accrued on the Series A Subordinated Debentures, a distribution of the Series
A Subordinated Debentures by the Series A Issuer could be a taxable event to the
Series A Issuer and the holders of the Series A QUIPS. See "Certain Federal
Income Tax Consequences -- Distribution of Series A Subordinated Debentures to
Holders of Series A QUIPS".
 
                                       S-8
<PAGE>   10
 
SHORTENING OF STATED MATURITY OF SERIES A SUBORDINATED DEBENTURES
 
     The Corporation will have the right at any time to shorten the maturity of
the Series A Subordinated Debentures to a date not earlier than             ,
2001 and thereby cause the Series A QUIPS to be redeemed on such earlier date.
The exercise of such right is subject to the Corporation having received prior
approval of the Federal Reserve if then required under applicable capital
guidelines or policies.
 
EXTENSION OF STATED MATURITY OF SERIES A SUBORDINATED DEBENTURES
 
     The Corporation will also have the right to extend the maturity of the
Series A Subordinated Debentures, whether or not the Series A Issuer is
liquidated and the Series A Subordinated Debentures are distributed to holders
of the Series A QUIPS, to a date no later than the 49th anniversary of the
initial issuance of the Series A QUIPS, provided that the Corporation can extend
the maturity only if at the time such election is made and at the time of such
extension (i) the Corporation is not in bankruptcy, otherwise insolvent or in
liquidation, (ii) the Corporation is not in default in the payment of any
interest or principal on the Series A Subordinated Debentures, (iii) if the
Series A Issuer has not been liquidated, the Series A Issuer is not in arrears
on payments of Distributions on the Series A QUIPS and no deferred Distributions
are accumulated and (iv) the Series A Subordinated Debentures are rated not less
than BBB- by Standard & Poor's Ratings Services or Baa3 by Moody's Investors
Service, Inc. or the equivalent by any other nationally recognized statistical
rating organization and (v) after such extension, the Series A Subordinated
Debentures do not have a remaining term to maturity of more than 30 years. To
the extent that the Stated Maturity of the Series A Subordinated Debentures is
extended at such time as the Series A QUIPS are outstanding, the Series A QUIPS
would remain outstanding until such extended date or until redeemed at an
earlier date.
 
MARKET PRICES
 
   
     There can be no assurance as to the market prices for Series A QUIPS or
Series A Subordinated Debentures that may be distributed in exchange for Series
A QUIPS upon liquidation of the Series A Issuer. Accordingly, the Series A QUIPS
that an investor may purchase, whether pursuant to the offer made hereby or in
the secondary market, or the Series A Subordinated Debentures that a holder of
Series A QUIPS may receive on liquidation of the Series A Issuer, may trade at a
discount to the price that the investor paid to purchase the Series A QUIPS
offered hereby. As a result of the existence of the Corporation's right to defer
interest payments, the market price of the Series A QUIPS (which represent
beneficial ownership interests in the Series A Issuer) may be more volatile than
the market prices of debt securities that are not subject to such optional
deferrals. In addition, because the Corporation has the right (i) to shorten the
Stated Maturity of the Series A Subordinated Debentures (subject to prior
approval of the Federal Reserve if then required under applicable capital
guidelines or policies) or (ii) to extend the maturity of the Series A
Subordinated Debentures (subject to the conditions described above), there can
be no assurance that the Corporation will not exercise its option to change the
maturity of the Series A Subordinated Debentures as permitted by the terms
thereof and of the Indenture. See "Certain Terms of Series A Subordinated
Debentures" and "Description of Junior Subordinated Debentures -- Corresponding
Junior Subordinated Debentures" in the accompanying Prospectus.
    
 
RIGHTS UNDER THE SERIES A GUARANTEE
 
     The Series A Guarantee guarantees to the holders of the Series A Securities
the following payments, to the extent not paid by the Series A Issuer: (i) any
accumulated and unpaid Distributions required to be paid on the Series A
Securities, to the extent that the Series A Issuer has funds on hand available
therefor at such time, (ii) the redemption price with respect to any Series A
Securities called for redemption, to the extent that the Series A Issuer has
funds on hand available therefor at such time, and (iii) upon a voluntary or
involuntary dissolution, winding up or
 
                                       S-9
<PAGE>   11
 
liquidation of the Series A Issuer (unless the Series A Subordinated Debentures
are distributed to holders of the Series A Securities), the lesser of (a) the
aggregate of the Liquidation Amount and all accumulated and unpaid Distributions
to the date of payment, to the extent that the Series A Issuer has funds on hand
available therefor at such time, and (b) the amount of assets of the Series A
Issuer remaining available for distribution to holders of the Series A
Securities after payment of creditors of the Series A Issuer as required by
applicable law. The Series A Guarantee will be qualified as an indenture under
the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). The
Bank of New York will act as the indenture trustee under the Series A Guarantee
(the "Guarantee Trustee") for the purpose of compliance with the Trust Indenture
Act and will hold the Series A Guarantee for the benefit of the holders of the
Series A Securities. The Bank of New York will also act as Debenture Trustee for
the Series A Subordinated Debentures and as Property Trustee and The Bank of New
York (Delaware) will act as Delaware Trustee under the Trust Agreement.
 
   
     The Series A Guarantee is subordinated as described under " -- Ranking of
Subordinated Obligations Under the Series A Guarantee and the Series A
Subordinated Debentures".
    
 
     The holders of not less than a majority in aggregate Liquidation Amount of
the Series A Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the Series A Guarantee or to direct the exercise of any trust power
conferred upon the Guarantee Trustee under the Series A Guarantee. Any holder of
the Series A Securities may institute a legal proceeding directly against the
Corporation to enforce its rights under the Series A Guarantee without first
instituting a legal proceeding against the Series A Issuer, the Guarantee
Trustee or any other person or entity. If the Corporation were to default on its
obligation to pay amounts payable under the Series A Subordinated Debentures,
the Series A Issuer would lack funds for the payment of Distributions or amounts
payable on redemption of the Series A Securities or otherwise, and, in such
event, holders of the Series A Securities would not be able to rely upon the
Series A Guarantee for payment of such amounts. Instead, if an event of default
under the Indenture shall have occurred and be continuing and such event is
attributable to the failure of the Corporation to pay interest on or principal
of the Series A Subordinated Debentures on the applicable payment date, then a
holder of Series A Securities may institute a legal proceeding directly against
the Corporation pursuant to the terms of the Indenture for enforcement of
payment to such holder of the principal of or interest on such Series A
Subordinated Debentures having a principal amount equal to the aggregate
Liquidation Amount of the Series A Securities of such holder (a "Direct
Action"). In connection with such Direct Action, the Corporation will have a
right of set-off under the Indenture to the extent of any payment made by the
Corporation to such holder of Series A Securities in the Direct Action. Except
as described herein, holders of Series A Securities will not be able to exercise
directly any other remedy available to the holders of the Series A Subordinated
Debentures or assert directly any other rights in respect of the Series A
Subordinated Debentures. See "Description of Junior Subordinated
Debentures -- Enforcement of Certain Rights by Holders of Preferred Securities,"
"-- Debenture Events of Default" and "Description of Guarantees" in the
accompanying Prospectus. The Trust Agreement provides that each holder of Series
A Securities by acceptance thereof agrees to the provisions of the Series A
Guarantee and the Indenture.
 
LIMITED VOTING RIGHTS
 
     Holders of Series A QUIPS generally will have limited voting rights
relating only to the modification of the Series A QUIPS and the exercise of the
Series A Issuer's rights as holder of Series A Subordinated Debentures and the
Series A Guarantee. Holders of Series A QUIPS will not be entitled to vote to
appoint, remove or replace the Property Trustee, the Delaware Trustee or any
Administrative Trustee, and such voting rights are vested exclusively in the
holder of the Series A Common Securities except, with respect to the Property
Trustee and the Delaware Trustee, upon the occurrence of certain events
described in the accompanying Prospectus. The Property Trustee,
 
                                      S-10
<PAGE>   12
 
   
the Administrative Trustees and the Corporation may amend the Trust Agreement
without the consent of holders of Series A QUIPS to ensure that the Series A
Issuer will not be taxable as a corporation or classified for United States
federal income tax purposes as a grantor trust unless such action materially and
adversely affects the interests of such holders. See "Description of Preferred
Securities -- Voting Rights; Amendment of Each Trust Agreement" and "-- Removal
of Issuer Trustees" in the accompanying Prospectus.
    
 
TRADING CHARACTERISTICS OF SERIES A QUIPS
 
   
     Application will be made to have the Series A QUIPS approved for quotation
on the NASDAQ National Market. The Series A QUIPS may trade at prices that do
not fully reflect the value of accrued and unpaid interest with respect to the
underlying Series A Subordinated Debentures. See "Certain Federal Income Tax
Consequences -- Interest Income and Original Issue Discount" and "-- Sales or
Redemption of Series A QUIPS" for a discussion of the United States federal
income tax consequences that may result from a taxable disposition of the Series
A QUIPS.
    
 
     As indicated above, application will be made to have the Series A QUIPS
approved for quotation on the NASDAQ National Market. If the Series A QUIPS are
not listed on the NASDAQ National Market or a national securities exchange and
the underwriters do not make a market for the securities, the liquidity of the
Series A QUIPS could be adversely affected.
 
POSSIBLE TAX LAW CHANGES AFFECTING THE SERIES A QUIPS
 
   
     On March 19, 1996, the Revenue Reconciliation Bill of 1996 (the "Bill") was
released which would, among other things, generally deny interest deductions for
interest on an instrument issued by a corporation that has a maximum weighted
average maturity of more than 20 years and that is not shown as indebtedness on
the separate balance sheet of the issuer or, where the instrument is issued to a
related party (other than a corporation), where the holder or some other related
party issues a related instrument that is not shown as indebtedness on the
issuer's consolidated balance sheet. The above-described provision of the Bill
was proposed to be effective generally for instruments issued on or after
December 7, 1995. If this provision were to apply to the Series A Subordinated
Debentures, the Corporation would not be able to deduct interest on the Series A
Subordinated Debentures. However, on March 29, 1996, the Chairmen of the Senate
Finance and House Ways and Means Committees issued a joint statement (the "Joint
Statement") to the effect that it was their intention that the effective date of
the President's legislative proposals, if adopted, would be no earlier than the
date of appropriate Congressional action. If the principles contained in the
Joint Statement were followed and the Bill were enacted, such legislation would
not apply to the Series A Subordinated Debentures. Although the 104th Congress
adjourned without enacting the Bill, there can be no assurance that future
legislative proposals or final legislation will not adversely affect the ability
of the Corporation to deduct interest on the Series A Subordinated Debentures or
otherwise affect the tax treatment of the transaction described herein. Such a
change could give rise to a Tax Event, which would permit the Corporation to
cause a redemption of the Series A QUIPS before           , 2001. The
Corporation has committed to the Reserve Bank that it will not cause any such
redemption without having received the prior approval of the Federal Reserve to

                           FIRST TENNESSEE CAPITAL I
 
     First Tennessee Capital I (the "Series A Issuer") is a statutory business
trust created under Delaware law pursuant to (i) the Trust Agreement executed by
the Corporation, as Depositor, The
 
                                      S-11
<PAGE>   13
 
Bank of New York, as Property Trustee, The Bank of New York (Delaware), as
Delaware Trustee, and the Administrative Trustees named therein, and (ii) the
filing of a certificate of trust with the Delaware Secretary of State on
December 6, 1996. The Series A Issuer's business and affairs are conducted by
the Issuer Trustees: The Bank of New York, as Property Trustee, and The Bank of
New York (Delaware), as Delaware Trustee, and two individual Administrative
Trustees who are employees or officers of or affiliated with the Corporation.
The Series A Issuer exists for the exclusive purposes of (i) issuing and selling
the Series A QUIPS and Series A Common Securities, (ii) using the proceeds from
the sale of Series A QUIPS and Series A Common Securities to acquire Series A
Subordinated Debentures issued by the Corporation and (iii) engaging in only
those other activities necessary or incidental thereto (such as registering the
transfer of the Series A Securities). Accordingly, the Series A Subordinated
Debentures will be the sole assets of the Series A Issuer, and payments under
the Series A Subordinated Debentures will be the sole revenue of the Series A
Issuer. All of the Series A Common Securities will be owned by the Corporation.
The Series A Common Securities will rank pari passu, and payments will be made
thereon pro rata, with the Series A QUIPS, except that upon the occurrence and
continuance of an event of default under the Trust Agreement resulting from an
event of default under the Indenture, the rights of the Corporation as holder of
the Series A Common Securities to payment in respect of Distributions and
payments upon liquidation, redemption or otherwise will be subordinated to the
rights of the holders of the Series A QUIPS. See "Description of Preferred
Securities -- Subordination of Common Securities" in the accompanying
Prospectus. The Corporation will acquire Series A Common Securities in an
aggregate Liquidation Amount equal to 3% of the total capital of the Series A
Issuer. The Series A Issuer has a term of 55 years, but may terminate earlier as
provided in the Trust Agreement. The principal executive office of the Series A
Issuer is 165 Madison Avenue, Memphis, Tennessee 38103, Attention: Treasurer,
and its telephone number is (901) 523-5630. See "The Issuers" in the
accompanying Prospectus.
 
     It is anticipated that the Series A Issuer will not be subject to the
reporting requirements under the Securities Exchange Act of 1934, as amended
(the "Exchange Act").

     The Corporation coordinates the financial resources of the consolidated
enterprise and maintains systems of financial, operational and administrative
control that allow coordination of selected policies and activities. The
Corporation's principal executive offices are located at 165 Madison Avenue,

         CONSOLIDATED RATIOS OF EARNINGS TO FIXED CHARGES AND COMBINED
            FIXED CHARGES AND PREFERRED STOCK DIVIDEND REQUIREMENTS
 
     For purposes of the following ratios, (i) earnings represent income from
continuing operations before income taxes, plus fixed charges, (ii) fixed
charges represent interest expense (excluding interest on deposits where
indicated) plus the estimated interest component of net rental expense and (iii)
combined fixed charges and preferred stock dividend requirements represent
interest expense (excluding interest on deposits where indicated), and an amount
equal to the pre-tax earnings required to meet applicable preferred stock
dividend requirements and the estimated interest component of net rental
expense. There were no shares of preferred stock outstanding during any of the
periods below indicated and therefore the ratio of earnings to combined fixed
charges and preferred stock dividend requirements would have been the same as
the ratio of earnings to fixed charges for each period indicated.

                                USE OF PROCEEDS
 
   
     The Corporation intends to use the proceeds from the sale of its Junior
Subordinated Debentures (including Corresponding Junior Subordinated Debentures
issued to the Issuers in connection with the investment by the Issuers of all of
the proceeds from the sale of Trust Securities) for general corporate purposes,
including, but not limited to, stock repurchases, the reduction of indebtedness,
investments in or extensions of credit to existing and future subsidiaries and
the financing of acquisitions.
    
 
     The Corporation is required by the Federal Reserve to maintain certain
levels of capital for bank regulatory purposes. On October 21, 1996, the Federal
Reserve announced that cumulative preferred securities having the
characteristics of the Series A QUIPS could be included as Tier 1 capital for
bank holding companies. Such Tier 1 capital treatment, together with the
Corporation's ability to deduct, for federal income tax purposes, interest
payable on the Series A Subordinated Debentures, will provide the Corporation
with a more cost-effective means of obtaining capital for bank regulatory
purposes than if the Corporation were to issue preferred stock.

                              ACCOUNTING TREATMENT
 
     For financial reporting purposes, the Series A Issuer will be treated as a
subsidiary of the Corporation and, accordingly, the accounts of the Series A
Issuer will be included in the consolidated financial statements of the
Corporation. The Series A QUIPS will be presented as a separate line item in the
consolidated balance sheets of the Corporation under the caption "Corporation
Obligated Mandatorily Redeemable Capital Securities of Subsidiary Trust Holding
Solely Junior Subordinated Deferrable Interest Debentures of the Corporation"
and appropriate disclosures about the Series A QUIPS, the Series A Guarantee and
the Series A Subordinated Debentures will be included in the notes to the
consolidated financial statements. For financial reporting purposes, the
Corporation will record Distributions payable on the Series A QUIPS as an
expense in the consolidated statements of income.
 
     The Corporation has agreed that future financial reports of the Corporation
will: (i) present the Preferred Securities issued by other Issuer trusts on the
Corporation's balance sheet as a separate line term entitled "Guaranteed
Preferred Beneficial Interests in Corporation's Junior Subordinated Deferrable
Interest Debentures"; (ii) include in a footnote to the financial statements
disclosure that the sole assets of the trusts are the Junior Subordinated
Debentures (specifying as to each trust the principal amount, interest rate and
maturity date of Junior Subordinated Debentures held); and (iii) if Staff
Accounting Bulletin 53 treatment is sought, then include, in an audited footnote
to the financial statements, disclosure that (a) the trusts are wholly owned,
(b) the sole assets of the trusts are the Junior Subordinated Debentures
(specifying as to each trust the principal amount, interest rate and maturity
date of the Junior Subordinated Debentures held), and (c) the obligations of the
Corporation under the Junior Subordinated Debentures, the Indenture, the
relevant trust agreement and the Guarantees, in the aggregate, constitute a full
and unconditional guarantee by the Corporation of the trusts' obligations under
the Preferred Securities issued by each trust.

                        CERTAIN TERMS OF SERIES A QUIPS
 
GENERAL
 
     The following summary of certain terms and provisions of the Series A QUIPS
supplements the description of the terms and provisions of the Preferred
Securities set forth in the accompanying Prospectus under the heading
"Description of Preferred Securities," to which description reference is hereby
made. This summary of certain terms and provisions of the Series A QUIPS, which
describes the material provisions thereof, does not purport to be complete and
is subject to, and is qualified in its entirety by reference to, the Trust
Agreement, to which reference is hereby made. The form of the Trust Agreement
has been filed as an exhibit to the Registration Statement of which this
Prospectus Supplement and accompanying Prospectus form a part.
 
DISTRIBUTIONS
 
   
     The Series A QUIPS represent beneficial ownership interests in the Series A
Issuer, and Distributions on each Series A QUIPS will be payable at the annual
rate of   % of the stated Liquidation Amount of $25, payable quarterly in
arrears on March 31, June 30, September 30 and December 31 of each year, to the
holders of the Series A QUIPS on the relevant record dates. The record dates for
the Series A QUIPS will be, for so long as the Series A QUIPS remain in
book-entry form, one Business Day (as defined in the accompanying Prospectus)
prior to the relevant Distribution payment date and, in the event the Series A
QUIPS are not in book-entry form, fifteen days prior to the relevant
Distribution payment date. Distributions will accumulate from the date of
original issuance. The first Distribution payment date for the Series A QUIPS
will be March 31, 1997. The amount of Distributions payable for any period will
be computed on the basis of a 360-day year of twelve 30-day months. In the event
that any date on which Distributions are payable on the Series A QUIPS is not a
Business Day, then payment of the Distributions payable on such date will be
made on the next succeeding day that is a Business Day (and without any
additional Distributions or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately preceding Business Day, in each case with the
same force and effect as if made on the date such payment was originally
payable. See "Description of Preferred Securities -- Distributions" in the
accompanying Prospectus.
    
 
     So long as no event of default under the Indenture has occurred and is
continuing, the Corporation has the right under the Indenture to defer payment
of interest on the Series A Subordinated Debentures at any time or from time to
time for a period not exceeding 20 consecutive quarters with respect to each
Extension Period, provided that no Extension Period may extend beyond the Stated
Maturity of the Series A Subordinated Debentures. As a consequence of any such
deferral of interest payments by the Corporation, quarterly Distributions on the
Series A QUIPS by the Series A Issuer will also be deferred during any such
Extension Period. Distributions to which holders of the Series A QUIPS are
entitled will accumulate additional Distributions thereon at the rate per annum
of   % thereof, compounded quarterly from the relevant payment date for such
Distributions. The term "Distributions" as used herein shall include any such
additional Distributions. During any such Extension Period, the Corporation may
not, and may not permit any subsidiary of the Corporation to, (i) declare or pay
any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Corporation's capital stock,
(ii) make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities of the Corporation (including other
series of Junior Subordinated Debentures) that rank pari passu with or junior in
interest to the Series A Subordinated Debentures or (iii) make any guarantee
payments with respect to any guarantee by the Corporation of the debt securities
of any subsidiary of the Corporation if such guarantee ranks pari passu with or
junior in interest to the Series A Subordinated Debentures (other than (a)
dividends or distributions in capital stock of the Corporation, (b) any
declaration of a dividend in connection with the implemen-
 
                                      S-17
<PAGE>   19
 
tation of a stockholders' rights plan or the redemption or repurchase of any
such rights pursuant thereto, (c) payments under the Series A Guarantee and (d)
purchases of common stock related to the issuance of common stock or rights or
options under any of the Corporation's benefit plans for its directors,
officers, employees or other persons within the definition of "employee" for
purposes of a registration of shares for an employee benefit plan of the
Corporation, related to the issuance of common stock or rights under a dividend
reinvestment and stock purchase plan, or related to the issuance of common stock
(or securities convertible into or exchangeable for common stock) as
consideration in an acquisition transaction). Prior to the termination of any
such Extension Period, the Corporation may further defer the payment of interest
on the Series A Subordinated Debentures, provided that no Extension Period may
exceed 20 consecutive quarters or extend beyond the Stated Maturity of the
Series A Subordinated Debentures. Upon the termination of any such Extension
Period and the payment of all interest then accrued and unpaid (together with
interest thereon at the rate of   %, compounded quarterly, to the extent
permitted by applicable law), the Corporation may elect to begin a new Extension
Period. There is no limitation on the number of times that the Corporation may
elect to begin an Extension Period. See "Certain Terms of Series A Subordinated
Debentures -- Option to Defer Interest Payments" and "Certain Federal Income Tax
Consequences -- Interest Income and Original Issue Discount".
 
     The Corporation has no current intention of exercising its right to defer
payments of interest by extending the interest payment period on the Series A
Subordinated Debentures.
 
REDEMPTION
 
     Upon the repayment or redemption, in whole or in part, of the Series A
Subordinated Debentures, whether at Stated Maturity or upon earlier redemption
as provided in the Indenture, the proceeds from such repayment or redemption
shall be applied by the Property Trustee to redeem a Like Amount (as defined in
the accompanying Prospectus) of the Trust Securities, upon not less than 30 nor
more than 60 days notice prior to the date fixed for repayment or redemption, at
a redemption price, with respect to the Series A QUIPS (the "Redemption Price"),
equal to the aggregate Liquidation Amount of such Series A QUIPS plus
accumulated and unpaid Distributions thereon to the date of redemption (the
"Redemption Date"). See "Description of Preferred Securities -- Redemption or
Exchange" in the accompanying Prospectus. For a description of the Stated
Maturity and redemption provisions of the Series A Subordinated Debentures, see
"Certain Terms of Series A Subordinated Debentures -- General" and
" -- Redemption".
 
LIQUIDATION OF SERIES A ISSUER AND DISTRIBUTION OF SERIES A SUBORDINATED
DEBENTURES TO HOLDERS
 
   
     The Corporation will have the right at any time to terminate the Series A
Issuer and cause the Series A Subordinated Debentures to be distributed to the
holders of the Series A QUIPS in exchange therefor upon liquidation of the
Series A Issuer. The Corporation has committed to the Reserve Bank that it will
not exercise its right to terminate the Series A Issuer without having received
the prior approval of the Federal Reserve to do so, if then required under
applicable Federal Reserve capital guidelines or policies.
    
 
     Under current United States federal income tax law and interpretations, a
distribution of Series A Subordinated Debentures in exchange for the Series A
QUIPS should not be a taxable event to holders of the Series A QUIPS. Should
there be a change in law, a change in legal interpretation, a Tax Event or other
circumstances, however, the distribution could be a taxable event to holders of
the Series A QUIPS. See "Certain Federal Income Tax Consequences -- Distribution
of Series A Subordinated Debentures to Holders of Series A QUIPS". If the
Corporation elects neither to redeem the Series A Subordinated Debentures prior
to maturity nor to liquidate the Series A Issuer and distribute the Series A
Subordinated Debentures to holders of the Series A QUIPS in exchange therefor,
the Series A QUIPS will remain outstanding until the Stated Maturity of the
Series A Subordinated Debentures.
 
                                      S-18
<PAGE>   20
 
     If the Corporation elects to liquidate the Series A Issuer and thereby
causes the Series A Subordinated Debentures to be distributed to holders of the
Series A QUIPS in exchange therefor upon liquidation of the Series A Issuer, the
Corporation shall continue to have the right to shorten or extend the maturity
of the Series A Subordinated Debentures, subject to certain conditions as
described under "Certain Terms of Series A Subordinated Debentures -- General".
 
LIQUIDATION VALUE
 
     The amount payable on the Series A QUIPS in the event of any liquidation of
the Series A Issuer is $25 per Series A QUIPS plus accumulated and unpaid
Distributions, which amount may be paid in the form of a distribution of a like
amount in Series A Subordinated Debentures, subject to certain exceptions. See
"Description of Preferred Securities -- Liquidation Distribution Upon
Termination" in the accompanying Prospectus.
 
REGISTRATION OF SERIES A QUIPS
 
     The Series A QUIPS will be represented by global certificates registered in
the name of DTC or its nominee. Beneficial interests in the Series A QUIPS will
be shown on, and transfers thereof will be effected only through, records
maintained by participants in DTC. Except as described below and in the
accompanying Prospectus, Series A QUIPS in certificated form will not be issued
in exchange for the global certificates. See "Book-Entry Issuance" in the
accompanying Prospectus.
 
     A global security shall be exchangeable for Series A QUIPS registered in
the names of persons other than DTC or its nominee only if (i) DTC notifies the
Series A Issuer that it is unwilling or unable to continue as a depositary for
such global security and no successor depositary shall have been appointed, or
if at any time DTC ceases to be a clearing agency registered as such under the
Exchange Act at a time when DTC is required to be so registered to act as such
depositary, (ii) the Issuer in its sole discretion determines that such global
security shall be so exchangeable or (iii) there shall have occurred and be
continuing an event of default under the Indenture with respect to the Series A
Subordinated Debentures. Any global security that is exchangeable pursuant to
the preceding sentence shall be exchangeable for definitive certificates
registered in such names as DTC shall direct. It is expected that such
instructions will be based upon directions received by DTC from its Participants
(as defined in the accompanying Prospectus) with respect to ownership of
beneficial interests in such global security. In the event that Series A QUIPS
are issued in definitive form, such Series A QUIPS will be in denominations of
$25 and integral multiples thereof and may be transferred or exchanged at the
offices described below.
 
   
     Payments on Series A QUIPS represented by a global security will be made to
DTC, as the depositary for the Series A QUIPS. In the event Series A QUIPS are
issued in certificated form, the Liquidation Amount and Distributions will be
payable, the transfer of the Series A QUIPS will be registrable, and Series A
QUIPS will be exchangeable for Series A QUIPS of other denominations of a like
aggregate Liquidation Amount, at the corporate office of the Property Trustee in
New York, New York, or at the offices of any paying agent or transfer agent
appointed by the Administrative Trustees, provided that payment of any
Distribution may be made at the option of the Administrative Trustees by check
mailed to the address of the persons entitled thereto, by wire transfer or by
direct deposit. In addition, if the Series A QUIPS are issued in certificated
form, the record dates for payment of Distributions will be fifteen days prior
to the relevant Distribution payment date. For a description of DTC and the
terms of the depositary arrangements relating to payments, transfers, voting
rights, redemptions and other notices and other matters, see "Book-Entry
Issuance" in the accompanying Prospectus.

               CERTAIN TERMS OF SERIES A SUBORDINATED DEBENTURES
 
GENERAL
 
     The following summary of certain terms and provisions of the Series A
Subordinated Debentures supplements the description of the terms and provisions
of the Corresponding Junior Subordinated Debentures (as defined in the
accompanying Prospectus) set forth in the accompanying Prospectus under the
heading "Description of Junior Subordinated Debentures" to which description
reference is hereby made. The summary of certain terms and provisions of the
Series A Subordinated Debentures set forth below, which describes the material
provisions thereof, does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, the Indenture, to which reference is
hereby made. The form of Indenture has been filed as an exhibit to the
Registration Statement of which this Prospectus Supplement and accompanying
Prospectus form a part.
 
   
     Concurrently with the issuance of the Series A QUIPS, the Series A Issuer
will invest the proceeds thereof, together with the consideration paid by the
Corporation for the Series A Common Securities, in the Series A Subordinated
Debentures issued by the Corporation. The Series A Subordinated Debentures will
bear interest at the annual rate of   % of the principal amount thereof, payable
quarterly in arrears on March 31, June 30, September 30 and December 31 of each
year (each, an "Interest Payment Date"), commencing March 31, 1997, to the
person in whose name each Series A Subordinated Debenture is registered at the
close of business on the relevant record date. The record dates for the Series A
Subordinated Debentures will be, for so long as they are held by an Issuer or in
Global form, the Business Day next preceding each Interest Payment Date and, in
the case of Series A Subordinated Debentures not held by on Issuer or in Global
form, fifteen days prior to each Interest Payment Date. It is anticipated that,
until the liquidation, if any, of the Series A Issuer, each Series A
Subordinated Debenture will be held in the name of the Property Trustee in trust
for the benefit of the holders of the Trust Securities. The amount of interest
payable for any period will be computed on the basis of a 360-day year of twelve
30-day months. In the event that any date on which interest is payable on the
Series A Subordinated Debentures is not a Business Day, then payment of the
interest 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 is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on the date such payment was
originally payable. Accrued interest that is not paid on the applicable Interest
Payment Date will bear additional interest on the amount thereof (to the extent
permitted by law) at the rate per annum of   % thereof, compounded quarterly
from the relevant Interest Payment Date. The term "interest" as used herein
shall include quarterly interest payments, interest on quarterly interest
payments not paid on the applicable Interest Payment Date and Additional Sums
(as defined below), as applicable.
    
 
     The Series A Subordinated Debentures will be issued as a series of junior
subordinated deferrable interest debentures under the Indenture.
 
   
     The Series A Subordinated Debentures will mature on               , 2026
(such date, as it may be shortened or extended as hereinafter described, the
"Stated Maturity"). Such date may be shortened at any time by the Corporation to
any date not earlier than             , 2001. The Corporation has committed to
the Reserve Bank that it will not shorten the Stated Maturity without having
received the prior approval of the Federal Reserve to do so, if then required
under applicable Federal Reserve capital guidelines or policies. Such date may
also be extended at any time at the election of the Corporation to any date not
later than             , 2045, provided that at the time such election is made
and at the time of extension (i) the Corporation is not in bankruptcy, otherwise
insolvent or in liquidation, (ii) the Corporation is not in default in the
payment of any interest or principal on the Series A Subordinated Debentures,
(iii) if the Series A Issuer has not been liquidated, the Series A Issuer is not
in arrears on payments of Distributions on the Series A QUIPS and no deferred
Distributions are accumulated, (iv) the Series A Subordinated Debentures
    
 
                                      S-20
<PAGE>   22
 
are rated not less than BBB- by Standard & Poor's Ratings Services or Baa3 by
Moody's Investors Service, Inc. or the equivalent by any other nationally
recognized statistical rating organization and (v) after such extension, the
Series A Subordinated Debentures do not have a remaining period to maturity of
more than 30 years. In the event that the Corporation elects to shorten or
extend the maturity of the Series A Subordinated Debentures, it shall give
notice to the Debenture Trustee, and the Debenture Trustee shall give notice of
such shortening or extension to the holders of the Series A Subordinated
Debentures no more than 30 and no less than 60 days prior to the effectiveness
thereof.
 
     The Series A Subordinated Debentures will be unsecured and will rank junior
and be subordinate in right of payment to all Senior Indebtedness of the
Corporation. See "Description of Junior Subordinated
Debentures -- Subordination" in the accompanying Prospectus. At September 30,
1996, the aggregate amount of Senior Indebtedness outstanding was approximately
$160 million. Because the Corporation is a holding company, the right of the
Corporation to participate in any distribution of assets of any subsidiary,
including the Bank, upon such subsidiary's liquidation or reorganization or
otherwise, is subject to the prior claims of creditors of that subsidiary,
except to the extent that the Corporation may itself be recognized as a creditor
of that subsidiary. Accordingly, the Series A Subordinated Debentures will be
effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and holders of Series A Subordinated Debentures
should look only to the assets of the Corporation for payments on the Series A
Subordinated Debentures. The Indenture does not limit the incurrence or issuance
of other secured or unsecured debt of the Corporation, including Senior
Indebtedness, whether under the Indenture, any existing indenture or any other
indenture that the Corporation may enter into in the future or otherwise. See
"Description of Junior Subordinated Debentures -- Subordination" in the
accompanying Prospectus.
 
OPTION TO DEFER INTEREST PAYMENTS
 
     So long as no event of default under the Indenture has occurred and is
continuing, the Corporation has the right under the Indenture at any time or
from time to time during the term of the Series A Subordinated Debentures to
defer payment of interest on the Series A Subordinated Debentures for a period
not exceeding 20 consecutive quarters with respect to each Extension Period,
provided that no Extension Period may extend beyond the Stated Maturity of the
Series A Subordinated Debentures. At the end of such Extension Period, the
Corporation must pay all interest then accrued and unpaid on the Series A
Subordinated Debentures (together with interest on such unpaid interest at the
annual rate of   %, compounded quarterly from the relevant Interest Payment
Date, to the extent permitted by applicable law). During an Extension Period,
interest will accrue and holders of Series A Subordinated Debentures (or holders
of Series A QUIPS while such series is outstanding) will be required to accrue
interest income for United States federal income tax purposes. See "Certain
Federal Income Tax Consequences -- Interest Income and Original Issue Discount".
 
     During any such Extension Period, the Corporation may not, and may not
permit any subsidiary of the Corporation to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of the Corporation's capital stock, (ii) make any payment
of principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities of the Corporation (including other series of Junior
Subordinated Debentures) that rank pari passu with or junior in interest to the
Series A Subordinated Debentures or (iii) make any guarantee payments with
respect to any guarantee by the Corporation of the debt securities of any
subsidiary of the Corporation if such guarantee ranks pari passu with or junior
in interest to the Series A Subordinated Debentures (other than (a) dividends or
distributions in capital stock of the Corporation, (b) any declaration of a
dividend in connection with the implementation of a stockholders' rights plan,
or the redemption or repurchase of any such rights pursuant thereto, (c)
payments under the Series A Guarantee, and (d) purchases of common stock related
to the issuance of common stock or rights or options under any of the
Corporation's benefit plans for its directors,
 
                                      S-21
<PAGE>   23
 
   
officers, employees or other persons within the definition of "employee" for
purposes of a registration of shares for an employee benefit plan of the
Corporation, related to the issuance of common stock or rights under a dividend
reinvestment and stock purchase plan, or related to the issuance of common stock
(or securities convertible into or exchangeable for common stock) as
consideration in an acquisition transaction). Prior to the termination of any
such Extension Period, the Corporation may further defer the payment of interest
on the Series A Subordinated Debentures, provided that no Extension Period may
exceed 20 consecutive quarters or extend beyond the Stated Maturity of the
Series A Subordinated Debentures. Upon the termination of any such Extension
Period and the payment of all interest then accrued and unpaid (together with
interest thereon at the rate of      %, compounded quarterly, to the extent
permitted by applicable law), the Corporation may elect to begin a new Extension
Period subject to the above requirements. No interest shall be due and payable
during an Extension Period, except at the end thereof. The Corporation must give
the Property Trustee, the Administrative Trustees and the Debenture Trustee
notice of its election to begin such Extension Period at least one Business Day
prior to the earlier of (i) the date interest on the Series A Subordinated
Debentures would have been payable except for the election to begin such
Extension Period, (ii) the date the Administrative Trustees are required to give
notice to the NASDAQ National Market or other applicable stock exchange or
automated quotation system on which the Series A QUIPS are then listed or quoted
or to holders of Series A Subordinated Debentures of the record date for such
Distributions or (iii) the date such Distributions are payable, but in any event
not less than one Business Day prior to such record date. The Debenture Trustee
shall give notice of the Corporation's election to begin a new Extension Period
to the holders of the Series A Subordinated Debentures. There is no limitation
on the number of times that the Corporation may elect to begin an Extension
Period. See "Description of Junior Subordinated Debentures -- Option to Defer
Interest Payments" in the accompanying Prospectus.
    
 
ADDITIONAL SUMS
 
     If the Series A Issuer is required to pay any additional taxes, duties or
other governmental charges as a result of a Tax Event, the Corporation will pay
as additional amounts on the Series A Subordinated Debentures such amounts as
shall be required so that the Distributions payable by the Series A Issuer shall
not be reduced as a result of any such additional taxes, duties or other
governmental charges.
 
REDEMPTION
 
   
     The Series A Subordinated Debentures are redeemable prior to maturity at
the option of the Corporation (i) on or after               , 2001, in whole at
any time or in part from time to time or (ii) at any time in whole (but not in
part) within 90 days following the occurrence and continuation of a Tax Event or
Capital Treatment Event, in either case at a redemption price equal to the
accrued and unpaid interest on the Series A Subordinated Debentures so redeemed
to the date fixed for redemption, plus 100% of the principal amount thereof. The
Corporation has committed to the Reserve Bank that it will not cause any such
redemption without having received the prior approval of the Federal Reserve to
do so, if then required under applicable Federal Reserve capital guidelines or
policies. See "Description of Junior Subordinated Debentures -- Redemption" in
the accompanying Prospectus.
    
 
DISTRIBUTION OF SERIES A SUBORDINATED DEBENTURES
 
     As described under "Certain Terms of Series A QUIPS -- Liquidation of
Series A Issuer and Distribution of Series A Subordinated Debentures to
Holders," under certain circumstances involving the termination of the Series A
Issuer, Series A Subordinated Debentures may be distributed to the holders of
the Series A QUIPS in exchange therefor upon liquidation of the Series A Issuer
after satisfaction of liabilities to creditors of the Series A Issuer as
provided by applicable law. If distributed to holders of Series A QUIPS, the
Series A Subordinated Debentures will initially be
 
                                      S-22
<PAGE>   24
 
issued in the form of one or more global securities and DTC, or any successor
depositary for the Series A QUIPS, will act as depositary for the Series A
Subordinated Debentures. It is anticipated that the depositary arrangements for
the Series A Subordinated Debentures would be substantially identical to those
in effect for the Series A QUIPS. If Series A Subordinated Debentures are
distributed to the holders of Series A QUIPS in exchange therefor upon the
liquidation of the Series A Issuer, the Corporation will use its best efforts to
have the Series A Subordinated Debentures approved for quotation on the NASDAQ
National Market or such stock exchanges or other automated quotation system, if
any, on which the Series A QUIPS are then listed or quoted. There can be no
assurance as to the market price of any Series A Subordinated Debentures that
may be distributed to the holders of Series A QUIPS.
 
REGISTRATION OF SERIES A SUBORDINATED DEBENTURES
 
   
     The Series A Subordinated Debentures will be registered in the name of the
Series A Issuer. In the event that the Series A Subordinated Debentures are
distributed to holders of Series A QUIPS, it is anticipated that the depositary
and other arrangements for the Series A Subordinated Debentures will be
substantially identical to those in effect for the Series A QUIPS as applicable.
See "Certain Terms of Series A QUIPS -- Registration of Series A QUIPS.

<PAGE>   25
 
                      CERTAIN TERMS OF SERIES A GUARANTEE
 
     The Series A Guarantee guarantees to the holders of the Series A Securities
the following payments, to the extent not paid by the Series A Issuer: (i) any
accumulated and unpaid Distributions required to be paid on the Series A
Securities, to the extent that the Series A Issuer has funds on hand available
therefor at such time, (ii) the redemption price with respect to any Series A
Securities called for redemption, to the extent that the Series A Issuer has
funds on hand available therefor at such time, and (iii) upon a voluntary or
involuntary dissolution, winding-up or liquidation of the Series A Issuer
(unless the Series A Subordinated Debentures are distributed to holders of the
Series A Securities), the lesser of (a) the aggregate of the Liquidation Amount
and all accumulated and unpaid Distributions to the date of payment, to the
extent that the Series A Issuer has funds on hand available therefor at such
time, and (b) the amount of assets of the Series A Issuer remaining available
for distribution to holders of the Series A Securities after payment of
creditors of the Series A Issuer as required by applicable law. The Series A
Guarantee will be qualified as an indenture under the Trust Indenture Act. The
Bank of New York will act as the Guarantee Trustee for the purposes of
compliance with the Trust Indenture Act and will hold the Series A Guarantee for
the benefit of the holders of the Series A Securities. The Bank of New York will
also act as Debenture Trustee for the Series A Subordinated Debentures and as
Property Trustee.
 
     The holders of not less than a majority in aggregate liquidation amount of
the Series A Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of the Series A Guarantee or to direct the exercise of any trust power
conferred upon the Guarantee Trustee under the Series A Guarantee. Any holder of
the Series A Securities may institute a legal proceeding directly against the
Corporation to enforce its rights under the Series A Guarantee without first
instituting a legal proceeding against the Series A Issuer, the Guarantee
Trustee or any other person or entity. If the Corporation were to default on its
obligation to pay amounts payable under the Series A Subordinated Debentures,
the Series A Issuer would lack funds for the payment of Distributions or amounts
payable on redemption of the Series A Securities or otherwise, and, in such
event, holders of the Series A Securities would not be able to rely upon the
Series A Guarantee for payment of such amounts. Instead, if an event of default
under the Indenture shall have occurred and be continuing and such event is
attributable to the failure of the Corporation to pay interest on or principal
of the Series A Subordinated Debentures on the applicable payment date, then a
holder of Series A Securities may institute a Direct Action against the
Corporation pursuant to the terms of the Indenture for enforcement of payment to
such holder of the principal of or interest on such Series A Subordinated
Debentures having a principal amount equal to the aggregate Liquidation Amount
of the Series A Securities of such holder. In connection with such Direct
Action, the Corporation will have a right of set-off under the Indenture to the
extent of any payment made by the Corporation to such holder of Series A
Securities in the Direct Action. Except as described herein, holders of Series A
Securities will not be able to exercise directly any other remedy available to
the holders of the Series A Subordinated Debentures or assert directly any other
rights in respect of the Series A Subordinated Debentures. See "Description of
Guarantees" in the accompanying Prospectus. The Trust Agreement provides that
each holder of Series A Securities by acceptance thereof agrees to the
provisions of the Series A Guarantee and the Indenture.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following is a summary of the principal United States federal income
tax consequences of the purchase, ownership and disposition of Series A QUIPS.
This summary only addresses the tax consequences to a person that acquires
Series A QUIPS on their original issue at their original offering price and that
is (i) an individual citizen or resident of the United States, (ii) a
corporation or partnership organized in or under the laws of the United States
or any state thereof or the District of Columbia or (iii) an estate or trust the
income of which is subject to United States federal income tax regardless of
source (a "United States Person"). This summary does not address all tax
consequences that may be applicable to a United States Person that is a
beneficial owner of Series A QUIPS, nor does it address the tax consequences to
(i) persons that are not United States Persons, (ii) persons that may be subject
to special treatment under United States federal income tax law, such as banks,
insurance companies, thrift institutions, regulated investment companies, real
estate investment trusts, tax-exempt organizations and dealers in securities or
currencies, (iii) persons that will hold Series A QUIPS as part of a position in
a "straddle" or as part of a "hedging," "conversion" or other integrated
investment transaction for federal income tax purposes, (iv) persons whose
functional currency is not the United States dollar or (v) persons that do not
hold Series A QUIPS as capital assets.
 
   
     The statements of law or legal conclusion set forth in this summary
constitute the opinion of Sullivan & Cromwell, special tax counsel to the
Corporation and the Series A Issuer. This summary is based upon the Internal
Revenue Code of 1986, as amended (the "Code"), Treasury Regulations, Internal
Revenue Service rulings and pronouncements and judicial decisions now in effect,
all of which are subject to change at any time. Such changes may be applied
retroactively in a manner that could cause the tax consequences to vary
substantially from the consequences described below, possibly adversely
affecting a beneficial owner of Series A QUIPS. In particular, legislation has
been proposed that could adversely affect the Corporation's ability to deduct
interest on the Series A Subordinated Debentures, which may in turn permit the
Corporation to cause a redemption of the Series A QUIPS. See "-- Possible Tax
Law Changes". The authorities on which this summary is based are subject to
various interpretations, and it is therefore possible that the federal income
tax treatment of the purchase, ownership and disposition of Series A QUIPS may
differ from the treatment described below.
    
 
     PROSPECTIVE INVESTORS ARE ADVISED TO CONSULT WITH THEIR OWN TAX ADVISORS IN
LIGHT OF THEIR OWN PARTICULAR CIRCUMSTANCES AS TO THE FEDERAL TAX CONSEQUENCES
OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF SERIES A QUIPS, AS WELL AS THE
EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.
 
CLASSIFICATION OF THE SERIES A ISSUER
 
   
     Under current law and assuming compliance with the terms of the Trust
Agreement, and certain similar factual matters, the Series A Issuer will not be
taxable as a corporation for United States federal income tax purposes. As a
result, each beneficial owner of Series A QUIPS (a "Securityholder") will be
required to include in its gross income its pro rata share of the interest
income, including original issue discount, paid or accrued with respect to the
Series A Subordinated Debentures whether or not cash is actually distributed to
the Securityholders. See "Interest Income and Original Issue Discount".
    
 
INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT
 
     Under recently issued Treasury regulations applicable to debt instruments
issued on or after August 13, 1996 (the "Regulations"), a "remote" contingency
that stated interest will not be timely paid will be ignored in determining
whether a debt instrument is issued with original issue discount ("OID"). The
Corporation believes that the likelihood of its exercising its option to defer
payments is remote. Based on the foregoing, the Corporation believes that the
Series A Subordinated Debentures will not be considered to be issued with OID at
the time of their original issuance and, accordingly, a Securityholder should
include in gross income such Securityholder's allocable share of interest on the
Series A Subordinated Debentures. The following discussion assumes that unless
 
                                      S-25
<PAGE>   27
 
   
and until the Corporation exercises its option to defer interest on the Series A
Subordinated Debentures, the Series A Subordinated Debentures will not be
considered as issued with OID.
    
 
     Under the Regulations, if the Corporation exercised its option to defer any
payment of interest, the Series A Subordinated Debentures would at that time be
treated as issued with OID, and all stated interest on the Series A Subordinated
Debentures would thereafter be treated as OID as long as the Series A
Subordinated Debentures remained outstanding. In such event, all of a holder's
taxable interest income with respect to the Series A Subordinated Debentures
would be accounted for as OID on an economic accrual basis regardless of such
Securityholder's method of tax accounting, and actual distributions of stated
interest would not be reported as taxable income. Consequently, a Securityholder
would be required to include in gross income OID even though the Corporation
would not make any actual cash payments during an Extension Period.
 
     The Regulations have not been addressed in any rulings or other
interpretations by the Internal Revenue Service (the "IRS"), and it is possible
that the IRS could take a position contrary to the interpretation herein.
 
     Because income on the Series A QUIPS will constitute interest or OID,
corporate Securityholders will not be entitled to a dividends-received deduction
with respect to any income recognized with respect to the Series A QUIPS.
 
     Subsequent uses of the term "interest" in this summary include income in
the form of OID.
 
DISTRIBUTION OF SERIES A SUBORDINATED DEBENTURES TO HOLDERS OF SERIES A QUIPS
 
     Under current law, a distribution by the Series A Issuer of the Series A
Subordinated Debentures as described under the caption 'Certain Terms of Series
A QUIPS -- Liquidation of Series A Issuer and Distribution of Series A
Subordinated Debentures to Holders" will be non-taxable and will result in the
Securityholder receiving directly its pro rata share of the Series A
Subordinated Debentures previously held indirectly through the Series A Issuer,
with a holding period and aggregate tax basis equal to the holding period and
aggregate tax basis such Securityholder had in its Series A QUIPS before such
distribution. If, however, the liquidation of the Series A Issuer were to occur
because the Series A Issuer is subject to United States federal income tax with
respect to income accrued or received on the Series A Subordinated Debentures,
the distribution of Series A Subordinated Debentures to Securityholders by the
Series A Issuer would be a taxable event to the Series A Issuer and each
Securityholder, and the Securityholder would recognize gain or loss as if the
Securityholder had exchanged its Series A QUIPS for the Series A Subordinated
Debentures it received upon the liquidation of the Series A Issuer. A
Securityholder will include interest in income in respect of Series A
Subordinated Debentures received from the Series A Issuer in the manner
described above under "Interest Income and Original Issue Discount".
 
SALES OR REDEMPTION OF SERIES A PREFERRED SECURITIES
 
     A Securityholder that sells (including a redemption for cash) Series A
QUIPS will recognize gain or loss equal to the difference between its adjusted
tax basis in the Series A QUIPS and the amount realized on the sale of such
Series A QUIPS. Assuming that the Corporation does not exercise its option to
defer payment of interest on the Series A Subordinated Debentures, and the
Series A QUIPS are not considered issued with OID, a Securityholder's adjusted
tax basis in the Series A QUIPS generally will be its initial purchase price. If
the Series A Subordinated Debentures are deemed to be issued with OID as a
result of the Corporation's deferral of any interest payment, a Securityholder's
tax basis in the Series A QUIPS generally will be its initial purchase price,
increased by OID previously includible in such Securityholder's gross income to
the date of disposition and decreased by distributions or other payments
received on the Series A QUIPS since and including the date of the first
Extension Period. Such gain or loss generally will be a capital gain or loss
(except to the extent any amount realized is treated as a payment of accrued
interest with respect to such holder's pro rata share of the Series A
Subordinated Debentures required to be included in income) and generally will be
a long-term capital gain or loss if the Series A QUIPS have been held for more
than one year.
 
                                      S-26
<PAGE>   28
 
   
     Should the Corporation exercise its option to defer any payment of interest
on the Series A Subordinated Debentures, the Series A QUIPS may trade at a price
that does not accurately reflect the value of accrued but unpaid interest with
respect to the underlying Series A Subordinated Debentures. In the event of such
a deferral, a Securityholder who disposes of its Series A QUIPS between record
dates for payments of Distributions thereon will be required to include in
income as ordinary income accrued but unpaid interest on the Series A
Subordinated Debentures to the date of disposition as OID and to add such amount
to its adjusted tax basis in its pro rata share of the underlying Series A
Subordinated Debentures deemed disposed of. To the extent the selling price is
less than the holder's adjusted tax basis, such Securityholder will recognize a
capital loss. Subject to certain limited exceptions, capital losses cannot be
applied to offset ordinary income for United States federal income tax purposes.
    
 
BACKUP WITHHOLDING TAX AND INFORMATION REPORTING
 
     The amount of interest income paid or accrued on the Series A QUIPS held of
record by United States Persons (other than corporations and other exempt
Securityholders) will be reported to the IRS. "Backup" withholding at a rate of
31% will apply to payments of interest to non-exempt United States Persons
unless the Securityholder furnishes its taxpayer identification number in the
manner prescribed in applicable Treasury Regulations, certifies that such number
is correct, certifies as to no loss of exemption from backup withholding and
meets certain other conditions.
 
     Payment of the proceeds from the disposition of Series A QUIPS to or
through the United States office of a broker is subject to information reporting
and backup withholding unless the holder or beneficial owner establishes an
exemption from information reporting and backup withholding.
 
     Any amounts withheld from a Securityholder under the backup withholding
rules will be allowed as a refund or a credit against such Securityholder's
United States federal income tax liability, provided the required information is
furnished to the IRS.
 
     It is anticipated that income on the Series A QUIPS will be reported to
holders on Form 1099 and mailed to holders of the Series A QUIPS by January 31
following each calendar year.
 
POSSIBLE TAX LAW CHANGES
 
   
     On March 19, 1996, the Revenue Reconciliation Bill of 1996 (the "Bill") was
released which would, among other things, generally deny interest deductions for
interest on an instrument issued by a corporation that has a maximum weighted
average maturity of more than 20 years and that is not shown as indebtedness on
the separate balance sheet of the issuer or, where the instrument is issued to a
related party (other than a corporation), where the holder or some other related
party issues a related instrument that is not shown as indebtedness on the
issuer's consolidated balance sheet. The above-described provision of the Bill
was proposed to be effective generally for instruments issued on or after
December 7, 1995. If this provision were to apply to the Series A Subordinated
Debentures, the Corporation would not be able to deduct interest on the Series A
Subordinated Debentures. However, on March 29, 1996, the Chairman of the Senate
Finance and House Ways and Means Committees issued a joint statement (the "Joint
Statement") to the effect that it was their intention that the effective date of
the President's legislative proposals, if adopted, would be no earlier than the
date of appropriate Congressional action. If the principles contained in the
Joint Statement were followed and the Bill were enacted, such legislation would
not apply to the Series A Subordinated Debentures. Although the 104th Congress
adjourned without enacting the Bill, there can be no assurance that future
legislative proposals or final legislation will not adversely affect the ability
of the Corporation to deduct interest on the Series A Subordinated Debentures or
otherwise affect the tax treatment of the transaction described herein. Such a
change could give rise to a Tax Event, which would permit the Corporation to
cause a redemption of the Series A QUIPS before                , 2001. The
Corporation has committed to the Reserve Bank that it will not cause any such
redemption without having received the prior approval of the Federal Reserve to
do so, if then required under applicable Federal Reserve capital guidelines or

     The Underwriters propose initially to offer the Series A QUIPS to the
public at the public offering price set forth on the cover page of this
Prospectus Supplement and to certain dealers at such price less a concession not
in excess of $.     per Series A QUIPS. The Underwriters may allow, and such
dealers may reallow, a discount not in excess of $.     per Series A QUIPS to
certain other dealers. After the initial public offering, the public offering
price, concession and discount may be changed.
 
     In view of the fact that the proceeds from the sale of the Series A QUIPS
will be used to purchase the Series A Subordinated Debentures issued by the
Corporation, the Underwriting Agreement provides that the Corporation will pay
as Underwriters' compensation for the Underwriters' arranging the investment
therein of such proceeds an amount of $.     per Series A QUIPS for the accounts
of the Underwriters.
 
     The Corporation and the Series A Issuer have agreed that, during the period
beginning from the date of the Underwriting Agreement and continuing to and
including the earlier of (i) the termination of trading restrictions on the
Series A QUIPS, as determined by the Underwriters, and (ii)   days after the
closing date, they will not offer, sell, contract to sell or otherwise dispose
of any Preferred Securities, any other beneficial interests in the assets of the
Series A Issuer, or any preferred securities or any other securities of the
Series A Issuer or the Corporation which are substantially similar to the Series
A QUIPS, including any guarantee of such securities, or any securities
convertible into or exchangeable for or representing the right to receive
preferred securities or any such substantially similar securities of either the
Series A Issuer or the Corporation, without the prior written consent of the
Underwriters, except for the Series A QUIPS offered in connection with this
offering.
 
     Prior to this offering, there has been no public market for the Series A
QUIPS. Application will be made to have the Series A QUIPS listed on the Nasdaq
National Market. Trading of the Series A QUIPS on the Nasdaq National Market is
expected to commence within a 30-day period after the initial delivery of the
Series A QUIPS. The Underwriters have advised the Corporation that they intend
to make a market in the Series A QUIPS prior to commencement of trading on the
Nasdaq National Market, but they are not obligated to do so and may discontinue
market making at any time without notice. No assurance can be given as to the
liquidity of the trading market for the Series A QUIPS.
 
     The Corporation and the Series A Issuer have agreed to indemnify the
Underwriters against, or contribute to payments that the Underwriters may be
required to make in respect of, certain liabilities, including liabilities under
the Securities Act of 1933, as amended.
 
     Certain of the Underwriters or their affiliates have provided from time to
time, and expect to provide in the future, investment or commercial banking
services to the Corporation and its affiliates, for which the Underwriters or
their affiliates have received or will receive customary fees and commissions.

     First Tennessee National Corporation, a Tennessee corporation (the
"Corporation"), may from time to time offer in one or more series or issuances
its junior subordinated deferrable interest debentures (the "Junior Subordinated
Debentures"). The Junior Subordinated Debentures will be unsecured and
subordinate and junior in right of payment to Senior Indebtedness (as defined in
"Description of Junior Subordinated Debentures -- Subordination") of the
Corporation. If provided in an accompanying Prospectus Supplement, the
Corporation will have the right to defer payments of interest on any series of
Junior Subordinated Debentures by extending the interest payment period thereon
at any time or from time to time for up to such number of consecutive interest
payment periods (which shall not extend beyond the Stated Maturity (as defined
herein) of the Junior Subordinated Debentures) with respect to each deferral
period as may be specified in such Prospectus Supplement (each, an "Extension
Period"). In such circumstance, however, the Corporation would not be permitted,
subject to certain exceptions set forth herein, to declare or pay any dividends,
distributions or other payments with respect to, or repay, repurchase, redeem or
otherwise acquire, the Corporation's capital stock or debt securities that rank
pari passu with or junior to such series of Junior Subordinated Debentures. See
"Description of Junior Subordinated Debentures -- Option to Defer Interest
Payments" and "-- Restrictions on Certain Payments".
 
   
     First Tennessee Capital I, First Tennessee Capital II, First Tennessee
Capital III and First Tennessee Capital IV, each a trust created under the laws
of the State of Delaware (each, an "Issuer," and collectively, the "Issuers"),
may severally offer, from time to time, preferred securities (the "Preferred
Securities") representing beneficial ownership interests in such Issuer. The
Corporation will be the owner of the common securities (the "Common Securities"
and, together with the Preferred Securities, the "Trust Securities")
representing common beneficial ownership interests in such Issuer. Holders of
the Preferred Securities will be entitled to receive preferential cumulative
cash distributions ("Distributions") accumulating from the date of original
issuance and payable periodically as specified in an accompanying Prospectus
Supplement.
    
     Concurrently with the issuance by an Issuer of its Preferred Securities,
such Issuer will invest the proceeds thereof and the proceeds of contributions
received in respect of the Common Securities in a corresponding series of the
Corporation's Junior Subordinated Debentures (the "Corresponding Junior
Subordinated Debentures") with terms corresponding to the terms of that Issuer's
Preferred Securities (the "Related Preferred Securities"). Accordingly, if, as
provided in an accompanying Prospectus

Supplement, the Corporation has the right to defer the payment of interest on a
series of Corresponding Junior Subordinated Debentures, then, if interest
payments are so deferred, Distributions on the Related Preferred Securities
would also be deferred, but would continue to accumulate at the rate per annum
set forth in the related Prospectus Supplement. See "Description of Preferred
Securities -- Distributions".
 
     Taken together, the Corporation's obligations under each series of
Corresponding Junior Subordinated Debentures, the Indenture and the related
Trust Agreement and the related Guarantee (each, as defined herein), in the
aggregate, provide a full, irrevocable and unconditional guarantee of payments
of Distributions and other amounts due on the Related Preferred Securities. See
"Relationship Among the Preferred Securities, the Corresponding Junior
Subordinated Debentures and the Guarantees -- Full and Unconditional Guarantee".
The payment of Distributions with respect to the Preferred Securities of each
Issuer and payments on liquidation of such Issuer or redemption of such
Preferred Securities, in each case out of funds held by such Issuer, are each
irrevocably guaranteed by the Corporation to the extent described herein (each,
a "Guarantee"). See "Description of Guarantees". The obligations of the
Corporation under each Guarantee will be unsecured and subordinate and junior in
right of payment to all Senior Indebtedness of the Corporation.
 
   
     The Corresponding Junior Subordinated Debentures will be the sole assets of
each Issuer, and payments under the Corresponding Junior Subordinated Debentures
and the related Expense Agreement will be the only revenue of each Issuer. If so
provided in an accompanying Prospectus Supplement, the Corporation may redeem
the Corresponding Junior Subordinated Debentures (and thereby cause the
redemption of the Trust Securities) or may terminate each Issuer and, after
satisfaction of liabilities to the creditors of such Issuer as required by
applicable law, cause the Corresponding Junior Subordinated Debentures to be
distributed to the holders of the Trust Securities in exchange therefor upon
liquidation of their interests in such Issuer. The Corporation has committed to
the Federal Reserve Bank of St. Louis (the "Reserve Bank") that the Corporation
will not take any such action without having received the prior approval of the
Board of Governors of the Federal Reserve System (the "Federal Reserve") to do
so, if then required under applicable Federal Reserve capital guidelines or
policies. See "Description of Preferred Securities -- Liquidation Distribution
Upon Termination".
    
 
   
     The Junior Subordinated Debentures and Preferred Securities may be offered
in amounts, at prices and on terms to be determined at the time of offering;
provided, however, the aggregate initial public offering price of all Junior
Subordinated Debentures (other than Corresponding Junior Subordinated
Debentures) and Preferred Securities (including the Corresponding Junior
Subordinated Debentures) issued pursuant to the Registration Statement of which
this Prospectus forms a part shall not exceed $300,000,000. Certain specific
terms of the Junior Subordinated Debentures or Preferred Securities in respect
of which this Prospectus is being delivered will be described in an accompanying
Prospectus Supplement, including without limitation and where applicable and to
the extent not set forth herein, (a) in the case of Junior Subordinated
Debentures, the specific designation, aggregate principal amount, denominations,
Stated Maturity (including any provisions for the shortening or extension
thereof), interest payment dates, interest rate (which may be fixed or variable)
or method of calculating interest, if any, applicable Extension Period or
interest deferral terms, if any, place or places where principal, premium, if
any, and interest, if any, will be payable, any terms of redemption, any sinking
fund provisions, terms for any conversion or exchange into other securities,
initial offering or purchase price, methods of distribution and any other
special terms, and (b) in the case of Preferred Securities, the identity of the
Issuer, specific title, aggregate stated liquidation amount, number of
securities, Distribution rate or method of calculating such rate, Distribution
payment dates, applicable Distribution deferral terms, if any, place or places
where Distributions will be payable, any terms of redemption, exchange, initial
offering or purchase price, methods of distribution and any other special terms.

     The Prospectus Supplement also will contain information, as applicable,
about certain United States federal income tax consequences relating to the
Junior Subordinated Debentures or Preferred Securities.
 
     The Junior Subordinated Debentures and Preferred Securities may be sold to
or through underwriters, through dealers, remarketing firms or agents or
directly to purchasers. See "Plan of Distribution." The names of any
underwriters, dealers, remarketing firms or agents involved in the sale of
Junior Subordinated Debentures or Preferred Securities in respect of which this
Prospectus is being delivered and any applicable fee, commission or discount
arrangements with them will be set forth in a Prospectus Supplement. The
Prospectus Supplement will state whether the Junior Subordinated Debentures or
Preferred Securities will be listed on any national securities exchange or
automated quotation system. If the Junior Subordinated Debentures or Preferred
Securities are not listed on any national securities exchange or automated
quotation system, there can be no assurance that there will be a secondary
market for the Junior Subordinated Debentures or Preferred Securities.
 
     This Prospectus may not be used to consummate sales of Junior Subordinated
Debentures or Preferred Securities unless accompanied by a Prospectus
Supplement.
 
                             AVAILABLE INFORMATION
 
     The Corporation is subject to the informational requirements of the

accordance therewith, files reports, proxy statements and other information with
the Securities and Exchange Commission (the "Commission"). Such reports, proxy

     The Corporation and the Issuers have filed with the Commission a
Registration Statement on Form S-3 (together with all amendments and exhibits
thereto, the "Registration Statement") under the Securities Act of 1933, as
amended (the "Securities Act"), with respect to the securities offered hereby.
This Prospectus does not contain all the information set forth in the
Registration Statement, certain portions of which have been omitted as permitted
by the rules and regulations of the Commission. For further information with
respect to the Corporation and the securities offered hereby, reference is made
to the Registration Statement and the exhibits and the financial statements,

by reference to the copy of such document filed as an exhibit to the
Registration Statement.
 
     No separate financial statements of any Issuer have been included herein.

registered as a bank holding company under the Bank Holding Company Act of 1956,
as amended (the "BHCA"). Through First Tennessee Bank National Association (the

financial services. At September 30, 1996, the Corporation had consolidated
total assets of approximately $12.8 billion and consolidated total deposits of
approximately $9.1 billion. As of September 30, 1996, the Corporation was one of

market capitalization.
 
     The Corporation's principal subsidiary is the Bank, which as of September
30, 1996 was the largest commercial bank headquartered in Tennessee both in
terms of total assets and deposits. At September 30, 1996, the Bank had total
assets of approximately $11.8 billion and total deposits of approximately $8.3
billion. The Corporation through its banking subsidiaries conducts a broad range
of retail and commercial banking and fiduciary services and had 241 banking
locations in Tennessee and 10 locations in northern Mississippi and 8 in
northwest Arkansas at September 30, 1996. The Corporation provides mortgage
banking services in 28 states. Through the Bank and its other subsidiaries, the
Corporation offers a comprehensive range of financial services, including

card products, merchant credit card processing, nation-wide check clearing,

                       CERTAIN REGULATORY CONSIDERATIONS
 
     The following discussion sets forth certain of the elements of the
comprehensive regulatory framework applicable to bank holding companies and
banks and provides certain specific information relevant to the Corporation and
its subsidiaries. Federal regulation of financial institutions such as the
Corporation and its subsidiaries is intended primarily for the protection of
depositors and the Federal Deposit Insurance Corporation Bank Insurance Fund
rather than shareholders or other creditors. See also "Available Information"
and "Incorporation of Certain Documents by Reference". To the extent that the
following information describes statutory and regulatory provisions, it is
qualified in its entirety by reference to the applicable statutory and
regulatory provisions. A change in applicable statutes, regulations or
regulatory policy may have a material effect on the business of the Corporation.
 
GENERAL
 
   
     As a bank holding company, the Corporation is subject to the regulation and
supervision of the Federal Reserve under the BHCA. Under the BHCA, bank holding
companies may not in general directly or indirectly acquire the ownership or
control of more than 5% of the voting shares or substantially all of the assets
of any company, including a bank, without the prior approval of the Federal
Reserve Board. The BHCA also restricts the types of activities in which a bank
holding company and its subsidiaries may engage. Generally, activities are
limited to banking and activities found by the Federal Reserve to be so closely
related to banking as to be a proper incident thereto.
    
 
   
     In addition, the BHCA permits the Federal Reserve to approve an application
by a bank holding company to acquire a bank located outside the acquiror's
principal state of operations without regard to whether the transaction is
prohibited under state law. See "-- Interstate Banking and Branching
Legislation". Effective September 29, 1995, the Tennessee Bank Structure Act of
1974 was amended to, among other things, prohibit (subject to certain
exceptions) a bank holding company from acquiring a bank for which the home
state is Tennessee (a "Tennessee Bank") if, upon consummation, the company would
directly or indirectly control 30% or more of the total deposits in insured
depository institutions in Tennessee. As of December 31, 1995, the Corporation
estimates that it held approximately 13% of such deposits. Subject to certain
exceptions, the Tennessee Bank Structure Act prohibits a bank holding company
from acquiring a bank in Tennessee which has been in operation for less than
five years. Tennessee law permits a Tennessee Bank to establish branches in any
county in Tennessee. Management cannot predict the extent to which the business
of the Corporation and its subsidiaries may be affected by recent federal and
Tennessee legislation relating to interstate and intrastate acquisitions and
branching activities.
    
 
     The Corporation's subsidiary banks (the "Subsidiary Banks") are subject to
supervision and examination by applicable federal and state banking agencies.
The Bank, First National Bank of Springdale, Springdale, Arkansas, and First
Tennessee Bank National Association Mississippi, Southaven, Mississippi, are
national banking associations, subject to regulation and supervision by the
Comptroller of the Currency (the "Comptroller") as their primary federal
regulator. The remaining Subsidiary Banks are Cleveland Bank and Trust Company,
Cleveland, Tennessee, and Peoples and Union Bank, Lewisburg, Tennessee, which
are Tennessee state-chartered banks, and Peoples Bank, Senatobia, Mississippi,
and Planters Bank, Tunica, Mississippi, which are Mississippi state-chartered
banks, none of which are members of the Federal Reserve System, and therefore
are subject to the regulations of and supervision by the Federal Deposit
Insurance Corporation (the "FDIC") as well as state banking authorities. In
addition, all of the Subsidiary Banks are insured by,
 
                                        5
<PAGE>   36
 
   
and subject to regulation by, the FDIC. The Subsidiary Banks are subject to
various requirements and restrictions under federal and state law, including
requirements to maintain reserves against deposits, restrictions on the types
and amounts of loans that may be granted and the interest that may be charged
thereon and limitations on the types of investments that may be made, activities
that may be engaged in, and types of services that may be offered. Various
consumer laws and regulations also affect the operations of the Subsidiary
Banks. In addition to the impact of such regulation, commercial banks are
affected significantly by the actions of the Federal Reserve as it attempts to
control the money supply and credit availability in order to influence the
economy.
    
 
PAYMENT OF DIVIDENDS
 
     The Corporation is a legal entity separate and distinct from its banking
and other subsidiaries. The principal source of cash flow of the Corporation,
including cash flow to pay dividends on its stock or principal (premium, if any)
and interest on debt securities, is dividends from the Subsidiary Banks. There
are statutory and regulatory limitations on the payment of dividends by the
Subsidiary Banks to the Corporation, as well as by the Corporation to its
shareholders.
 
     Each Subsidiary Bank that is a national bank is required by federal law to
obtain the prior approval of the Comptroller for the payment of dividends if the
total of all dividends declared by the board of directors of such Subsidiary
Bank in any year will exceed the total of (i) its net profits (as defined and
interpreted by regulation) for that year plus (ii) the retained net profits (as
defined and interpreted by regulation) for the preceding two years, less any
required transfers to surplus. A national bank also can pay dividends only to
the extent that retained net profits (including the portion transferred to
surplus) exceed bad debts (as defined by regulation).
 
     State-chartered banks are subject to varying restrictions on the payment of
dividends under applicable state laws. Tennessee law imposes dividend
restrictions on Tennessee state banks substantially similar to those imposed
under federal law on national banks, as described above. Mississippi law
prohibits Mississippi state banks from declaring a dividend without the prior
written approval of the Mississippi Banking Commissioner.
 
   
     If, in the opinion of the applicable federal bank regulatory authority, a
depository institution or a holding company is engaged in or is about to engage
in an unsafe or unsound practice (which, depending on the financial condition of
the depository institution or holding company, could include the payment of
dividends), such authority may require that such institution or holding company
cease and desist from such practice. The federal banking agencies have indicated
that paying dividends that deplete a depository institution's or holding
company's capital base to an inadequate level would be such an unsafe and
unsound banking practice. Moreover, the Federal Reserve, the Comptroller and the
FDIC have issued policy statements which provide that bank holding companies and
insured depository institutions generally should only pay dividends out of
current operating earnings.
    
 
     In addition, under the Federal Deposit Insurance Act ("FDIA"), an
FDIC-insured depository institution may not make capital distributions
(including the payment of dividends) or pay any management fees to its holding
company or pay any dividend if it is undercapitalized or if such payment would
cause it to become undercapitalized.
 
     At December 31, 1995, under dividend restrictions imposed under applicable
federal and state laws, the Subsidiary Banks, without obtaining regulatory
approval, could legally declare aggregate dividends of approximately $236
million.
 
     The payment of dividends by the Corporation and the Subsidiary Banks may
also be affected or limited by other factors, such as the requirement to
maintain adequate capital above regulatory guidelines and debt covenants.
 
TRANSACTIONS WITH AFFILIATES
 
     There are various legal restrictions on the extent to which the Corporation
and its nonbank subsidiaries can borrow or otherwise obtain credit from the
Subsidiary Banks. There are also legal
 
                                        6
<PAGE>   37
 
restrictions on the Subsidiary Banks' purchases of or investments in the
securities of and purchases of assets from the Corporation and its nonbank
subsidiaries, a Subsidiary Bank's loans or extensions of credit to third parties
collateralized by the securities or obligations of the Corporation and its
nonbank subsidiaries, the issuance of guarantees, acceptances and letters of
credit on behalf of the Corporation and its nonbank subsidiaries, and certain
bank transactions with the Corporation and its nonbank subsidiaries, or with
respect to which the Corporation and its nonbank subsidiaries act as agent,
participate or have a financial interest. Subject to certain limited exceptions,
a Subsidiary Bank (including for purposes of this paragraph all subsidiaries of
such Subsidiary Bank) may not extend credit to the Corporation or to any other
affiliate (other than another Subsidiary Bank and certain exempted affiliates)
in an amount which exceeds 10% of the Subsidiary Bank's capital stock and
surplus and may not extend credit in the aggregate to all such affiliates in an
amount which exceeds 20% of its capital stock and surplus. Further, there are
legal requirements as to the type, amount and quality of collateral which must
secure such extensions of credit by the Subsidiary Banks to the Corporation or
to such other affiliates. Also, extensions of credit and other transactions
between a Subsidiary Bank and the Corporation or other such affiliates must be
on terms and under circumstances, including credit standards, that are
substantially the same or at least as favorable to such Subsidiary Bank as those
prevailing at the time for comparable transactions with non-affiliated
companies. Also, the Corporation and its subsidiaries are prohibited from
engaging in certain tie-in arrangements in connection with any extension of
credit, lease or sale of property or furnishing of services.
 
CAPITAL ADEQUACY
 
   
     The Federal Reserve has adopted risk-based capital guidelines for bank
holding companies. The minimum guideline for the ratio of total capital ("Total
Capital") to risk-weighted assets (including certain off-balance-sheet items,
such as standby letters of credit) is 8% and the minimum ratio of Tier 1 Capital
(defined below) to risk-weighted assets is 4%. At least half of the Total
Capital must be composed of common stock, minority interests in the equity
accounts of consolidated subsidiaries, noncumulative perpetual preferred stock
and a limited amount of cumulative perpetual preferred stock, less goodwill and
certain other intangible assets ("Tier 1 Capital"). The remainder may consist of
qualifying subordinated debt, certain types of mandatory convertible securities
and perpetual debt, other preferred stock and a limited amount of loan loss
reserves. At September 30, 1996, the Corporation's consolidated Tier 1 Capital
and Total Capital ratios were 9.14% and 12.02%, respectively.
    
 
   
     In addition, the Federal Reserve has established minimum leverage ratio
guidelines for bank holding companies. These guidelines provide for a minimum
ratio of Tier 1 Capital to quarterly average assets, less goodwill and certain
other intangible assets (the "Leverage Ratio"), of 3% for bank holding companies
that meet certain specific criteria, including having the highest regulatory
rating. All other bank holding companies generally are required to maintain a
Leverage Ratio of at least 3%, plus an additional cushion of at least 100 to 200
basis points. The Corporation's Leverage Ratio at September 30, 1996 was 6.67%.
The guidelines also provide that bank holding companies experiencing internal
growth or making acquisitions will be expected to maintain strong capital
positions substantially above the minimum supervisory levels without significant
reliance on intangible assets. Furthermore, the Federal Reserve has indicated
that it will consider a "tangible Tier 1 Capital leverage ratio" (deducting all
intangibles) and other indicia of capital strength in evaluating proposals for
expansion or new activities.
    
 
     Each of the Subsidiary Banks is subject to risk-based and leverage capital
requirements similar to those described above adopted by the Comptroller or the
FDIC, as the case may be. The Corporation believes that each of the Subsidiary
Banks was in compliance with applicable minimum capital requirements as of
September 30, 1996. Neither the Corporation nor any of the Subsidiary Banks has
been advised by any federal banking agency of any specific minimum Leverage
Ratio requirement applicable to it.
 
                                        7
<PAGE>   38
 
     Failure to meet capital guidelines could subject a bank to a variety of
enforcement remedies, including the termination of deposit insurance by the
FDIC, and to certain restrictions on its business and in certain circumstances
to the appointment of a conservator or receiver. See "-- Prompt Corrective
Action".
 
     The Federal Deposit Insurance Corporation Improvement Act of 1991 required
each federal banking agency to revise its risk-based capital standards within 18
months of enactment of the statute to ensure that those standards take adequate
account of interest rate risk, concentration of credit risk and the risk of
non-traditional activities, as well as reflect the actual performance and
expected risk of loss on multifamily mortgages. On December 15, 1994, the
federal banking agencies adopted amendments to their respective risk-based
capital requirements that explicitly identify concentration of credit risk and
certain risks arising from non-traditional activities, and the management of
such risks, as important factors to consider in assessing an institution's
overall capital adequacy. The amendments do not, however, mandate any specific
adjustments to the risk-based capital calculations as a result of such factors.
 
     On August 2, 1995, the federal banking agencies published amendments to
their risk-based capital rules that, effective September 1, 1995, include
interest-rate risk as a qualitative factor to be considered in assessing capital
adequacy. Concurrent with the publication of the amendments, the federal banking
agencies proposed a system for measuring interest-rate risk and announced their
intention, after a trial period, to evaluate the reliability and accuracy of the
proposed system and to initiate a rulemaking process for the purpose of amending
the risk-based capital rules to include an explicit capital charge for
interest-rate risk that will be based upon the level of a bank's measured
interest-rate risk exposure.
 
     In August 1996, the federal banking regulators adopted amendments to their
risk-based capital rules to incorporate a measure for market risk in foreign
exchange and commodity activities and in the trading of debt and equity
instruments. These amendments, which become effective at year end 1997, will
require banks with relatively large trading activities to calculate a capital
charge for market risk using their own internal value-at-risk models (subject to
parameters set by the regulators) or, alternatively, risk management techniques
developed by the regulators. As a result, in addition to existing capital
requirements for credit risk, certain institutions will be required to hold
capital based on the measure of their market risk exposure. These institutions
will be able to satisfy this additional requirement, in part, by issuing
short-term subordinated debt that qualifies as Tier 3 capital.
 
HOLDING COMPANY STRUCTURE AND SUPPORT OF SUBSIDIARY BANKS
 
     Because the Corporation is a holding company, its right to participate in
the assets of any subsidiary upon the latter's liquidation or reorganization
will be subject to the prior claims of the subsidiary's creditors (including
depositors in the case of the Subsidiary Banks) except to the extent that the
Corporation may itself be a creditor with recognized claims against the
subsidiary. In addition, depositors of bank, and the FDIC as their subrogee,
would be entitled to priority over other creditors in the event of liquidation
of a bank subsidiary.
 
   
     Under Federal Reserve policy, the Corporation is expected to act as a
source of financial strength to, and to commit resources to support, each of the
Subsidiary Banks. This support may be required at times when, absent such
Federal Reserve policy, the Corporation may not be inclined to provide it. In
addition, any capital loans by a bank holding company to any of its subsidiary
banks are subordinate in right of payment to deposits and to certain other
indebtedness of such subsidiary banks. In the event of a bank holding company's
bankruptcy, any commitment by the bank holding company to a federal bank
regulatory agency to maintain the capital of a subsidiary bank will be assumed
by the bankruptcy trustee and entitled to a priority of payment.
    
 
CROSS-GUARANTEE LIABILITY
 
     Under the FDIA, a depository institution insured by the FDIC can be held
liable for any loss incurred by, or reasonably expected to be incurred by, the
FDIC after August 9, 1989 in connection
 
                                        8
<PAGE>   39
 
with (i) the default of a commonly controlled FDIC-insured depository
institution or (ii) any assistance provided by the FDIC to any commonly
controlled FDIC-insured depository institution "in danger of default." "Default"
is defined generally as the appointment of a conservator or receiver and "in
danger of default" is defined generally as the existence of certain conditions
indicating that a default is likely to occur in the absence of regulatory
assistance. The FDIC's claim for damages is superior to claims of shareholders
of the insured depository institution or its holding company but is subordinate
to claims of depositors, secured creditors and holders of subordinated debt
(other than affiliates) of the commonly controlled insured depository
institution. The Subsidiary Banks are subject to these cross-guarantee
provisions. As a result, any loss suffered by the FDIC in respect of any of the
Subsidiary Banks would likely result in assertion of the cross-guarantee
provisions, the assessment of such estimated losses against the Corporation's
other Subsidiary Banks and a potential loss of the Corporation's investment in
such other Subsidiary Banks.
 
PROMPT CORRECTIVE ACTION
 
     The FDIA requires, among other things, the federal banking regulators to
take "prompt corrective action" in respect of FDIC-insured depository
institutions that do not meet minimum capital requirements. Under the FDIA,
insured depository institutions are divided into five capital tiers: "well
capitalized," "adequately capitalized," "undercapitalized," "significantly
undercapitalized" and "critically undercapitalized." Under applicable
regulations, an institution is defined to be well capitalized if it maintains a
Leverage ratio of at least 5%, a Tier 1 Capital ratio of at least 6% and a Total
Capital ratio of at least 10% and is not subject to a directive, order or
written agreement to meet and maintain specific capital levels. An institution
is defined to be adequately capitalized if it meets all of the minimum capital
requirements as described above. An institution will be considered
undercapitalized if it fails to meet any minimum required measure; significantly
undercapitalized if it has a Total Risk-Based Capital Ratio of less than 6%, a
Tier 1 Risk-Based Capital Ratio of less than 3% or a Leverage Ratio of less than
3%; and critically undercapitalized if it fails to maintain a level of tangible
equity equal to at least 2% of total assets. An institution may be deemed to be
in a capitalization category that is lower than is indicated by its actual
capital position if it receives an unsatisfactory examination rating.
 
     The FDIA generally prohibits a FDIC-insured depository institution from
making any capital distribution (including payment of dividends) or paying any
management fee to its holding company if the depository institution would
thereafter be undercapitalized. Undercapitalized depository institutions are
subject to restrictions on borrowing from the Federal Reserve System. In
addition, undercapitalized depository institutions are subject to growth
limitations and are required to submit capital restoration plans. An insured
depository institution's holding company must guarantee the capital plan, up to
an amount equal to the lesser of 5% of the depository institution's assets at
the time it becomes undercapitalized or the amount of the capital deficiency
when the institution fails to comply with the plan for the plan to be accepted
by the applicable federal regulatory authority. The federal banking agencies may
not accept a capital plan without determining, among other things, that the plan
is based on realistic assumptions and is likely to succeed in restoring the
depository institution's capital. If a depository institution fails to submit an
acceptable plan, it is treated as if it is significantly undercapitalized.
 
     Significantly undercapitalized insured depository institutions may be
subject to a number of requirements and restrictions, including orders to sell
sufficient voting stock to become adequately capitalized, requirements to reduce
total assets and cessation of receipt of deposits from correspondent banks.
Critically undercapitalized insured depository institutions are subject to
appointment of a receiver or conservator, generally within 90 days of the date
on which they become critically undercapitalized.
 
     The Corporation believes that at September 30, 1996 all of the Subsidiary
Banks had sufficient capital to qualify as "well capitalized" under the
regulatory capital requirements discussed above.

INTERSTATE BANKING AND BRANCHING LEGISLATION
 
     The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994
(the "IBBEA") authorizes interstate acquisitions of banks and bank holding
companies without geographic limitation beginning one year after enactment. In
addition, beginning June 1, 1997, a bank may merge with a bank in another state
as long as neither of the states has opted out of interstate branching between
the date of enactment of the IBBEA and May 31, 1997. The IBBEA further provides
that states may enact laws permitting interstate merger transactions prior to
June 1, 1997. A bank may establish and operate a de novo branch in a state in
which the bank does not maintain a branch if that state expressly permits de
novo branching. Once a bank has established branches in a state through an
interstate merger transaction, the bank may establish and acquire additional
branches at any location in the state where any bank involved in the interstate
merger transaction could have established or acquired branches under applicable
federal or state law. A bank that has established a branch in a state through de
novo branching may establish and acquire additional branches in such state in
the same manner and to the same extent as a bank having a branch in such state
as a result of an interstate merger. If a state opts out of interstate branching
within the specified time period, no bank in any other state may establish a
branch in the opting out of state, whether through an acquisition or de novo.
 
FDIC INSURANCE ASSESSMENTS; DIFA
 
     The FDIC reduced the insurance premiums it charges on bank deposits insured
by the Bank Insurance Fund ("BIF") to the statutory minimum of $2,000.00 for
"well capitalized" banks, effective January 1, 1996. Premiums related to
deposits assessed by the Savings Association Insurance Fund ("SAIF"), including
savings association deposits acquired by banks, continued to be assessed at a
rate of between 23 cents and 31 cents per $100.00 of deposits. On September 30,
1996, the Deposit Insurance Funds Act of 1996 ("DIFA") was enacted and signed
into law. DIFA provided for a special assessment to recapitalize the SAIF to
bring the SAIF up to statutory required levels. The assessment imposed a
one-time fee to banks that own previously acquired thrift deposits of $.526 per
$100 of thrift deposits they held at March 31, 1995. The pre-tax cost to the
Corporation of the one-time assessment in the third quarter of 1996 was $3.8
million. DIFA further provides for assessments to be imposed on insured
depository institutions with respect to deposits insured by the BIF (in addition
to assessments currently imposed on depository institutions with respect to
SAIF-insured deposits) to pay for the cost of Financing Corporation ("FICO")
bonds. All banks will be assessed to pay the interest due on FICO bonds starting
on January 1, 1997. The Corporation expects the cost to the Corporation to be
immaterial.
 
     Under the FDIA, insurance of deposits may be terminated by the FDIC upon a
finding that the institution has engaged in unsafe and unsound practices, is in
an unsafe or unsound condition to continue operations or has violated any
applicable law, regulation, rule, order or condition imposed by a federal bank
regulatory agency.
 
DEPOSITOR PREFERENCE
 
     Federal law provides that deposits and certain claims for administrative
expenses and employee compensation against an insured depository institution
would be afforded a priority over other general unsecured claims against such an
institution, including the Junior Subordinated Debentures, in the "liquidation
or other resolution" of such an institution by any receiver.

                                  THE ISSUERS
 
   
     Each Issuer is a statutory business trust created under Delaware law
pursuant to (i) a trust agreement executed by the Corporation, as Depositor of
the Issuer, and the Delaware Trustee and two Administrative Trustees (as defined
herein) of such Issuer and (ii) the filing of a certificate of trust with the
Delaware Secretary of State. Each trust agreement will be amended and restated
in its entirety (each, as so amended and restated, a "Trust Agreement")
substantially in the form filed as an exhibit to the Registration Statement of
which this Prospectus forms a part. Each Trust Agreement will be qualified as an
indenture under the Trust Indenture Act of 1939, as amended (the "Trust
Indenture Act"). Each Issuer exists for the exclusive purposes of (i) issuing
and selling its Trust Securities, (ii) using the proceeds from the sale of such
Trust Securities to acquire a series of Corresponding Junior Subordinated
Debentures issued by the Corporation, and (iii) engaging in only those other
activities necessary or incidental thereto (such as registering the transfer of
Trust Securities). Accordingly, the Corresponding Junior Subordinated Debentures
will be the sole assets of each Issuer, and payments under the Corresponding
Junior Subordinated Debentures will be the sole revenue of each Issuer.
    
 
     All of the Common Securities of each Issuer will be owned by the
Corporation. The Common Securities of an Issuer will rank pari passu, and
payments will be made thereon pro rata, with the Preferred Securities of such
Issuer, except that upon the occurrence and continuance of an event of default
under a Trust Agreement resulting from an event of default under the Indenture,
the rights of the Corporation as holder of the Common Securities to payment in
respect of Distributions and payments upon liquidation or redemption will be
subordinated to the rights of the holders of the Preferred Securities of such
Issuer. See "Description of Preferred Securities -- Subordination of Common
Securities". The Corporation will acquire Common Securities in an aggregate
Liquidation Amount equal to not less than 3% of the total capital of each
Issuer.
 
     Unless otherwise specified in the applicable Prospectus Supplement, each
Issuer has a maximum term of approximately 55 years, but may terminate earlier
as provided in the applicable Trust Agreement. Each Issuer's business and
affairs are conducted by its trustees, each appointed by the Corporation as
holder of the Common Securities. The trustees for each Issuer will be The Bank
of New York, as the Property Trustee (the "Property Trustee"), The Bank of New
York (Delaware), as the Delaware Trustee (the "Delaware Trustee"), and two
individual trustees (the "Administrative Trustees") who are employees or
officers of or affiliated with the Corporation (collectively, the "Issuer
Trustees"). The Bank of New York, as Property Trustee, will act as sole trustee
under each Trust Agreement for purposes of compliance with the Trust Indenture
Act. The Bank of New York will also act as trustee under the Guarantees and the
Indenture. See "Description of Guarantees" and "Description of Junior
Subordinated Debentures". The holder of the Common Securities of an Issuer, or
the holders of a majority in Liquidation Amount of the Related Preferred
Securities if an event of default under the Trust Agreement for such Issuer has
occurred and is continuing, will be entitled to appoint, remove or replace the
Property Trustee and/or the Delaware Trustee for such Issuer. In no event will
the holders of the Preferred Securities have the right to vote to appoint,
remove or replace the Administrative Trustees; such voting rights are vested
exclusively in the holder of the Common Securities. The duties and obligations
of each of the Issuer Trustees are governed by the applicable Trust Agreement.
The Corporation will pay all fees and expenses related to each Issuer and the
offering of the Preferred Securities and will pay, directly or indirectly, all
ongoing costs, expenses and liabilities of each Issuer.
 
   
     The principal executive office of each Issuer is 165 Madison Avenue,
Memphis, Tennessee 38103 and its telephone number is (901) 523-5630.

                                USE OF PROCEEDS
 
   
     Except as otherwise set forth in the applicable Prospectus Supplement, the
Corporation intends to use the proceeds from the sale of its Junior Subordinated
Debentures (including Corresponding Junior Subordinated Debentures issued to an
Issuer in connection with the investment by such Issuer of all of the proceeds
from the sale of Trust Securities) for general corporate purposes, including,
but not limited to, stock repurchases, the reduction of indebtedness,
investments in or extensions of credit to existing and future subsidiaries and
the financing of acquisitions or such other uses as may be set forth in the
applicable Prospectus Supplement.
    
 
                 DESCRIPTION OF JUNIOR SUBORDINATED DEBENTURES
 
     The Junior Subordinated Debentures are to be issued in one or more series
under a Junior Subordinated Indenture, as supplemented from time to time (as so
supplemented, the "Indenture"), between the Corporation and The Bank of New
York, as trustee (the "Debenture Trustee"). This summary of certain terms and
provisions of the Junior Subordinated Debentures, Corresponding Junior
Subordinated Debentures and the Indenture, which summarizes the material
provisions thereof, does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, the Indenture, the form of which is
filed as an exhibit to the Registration Statement of which this Prospectus forms
a part, and to the Trust Indenture Act, to each of which reference is hereby
made. The Indenture is qualified under the Trust Indenture Act. Whenever
particular defined terms of the Indenture (as supplemented or amended from time
to time) are referred to herein or in a Prospectus Supplement, such defined
terms are incorporated herein or therein by reference.
 
GENERAL
 
   
     Each series of Junior Subordinated Debentures will rank pari passu with all
other series of Junior Subordinated Debentures and will be unsecured and
subordinate and junior in right of payment to the extent and in the manner set
forth in the Indenture to all Senior Indebtedness (as defined below) of the
Corporation. See "-- Subordination". Because the Corporation is a holding
company, the right of the Corporation to participate in any distribution of
assets of any subsidiary, including the Bank, upon such subsidiary's liquidation
or reorganization or otherwise, is subject to the prior claims of creditors of
the subsidiary, except to the extent the Corporation may itself be recognized as
a creditor of that subsidiary. Accordingly, the Junior Subordinated Debentures
will be effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and holders of Junior Subordinated Debentures should
look only to the assets of the Corporation for payments on the Junior
Subordinated Debentures. Except as otherwise provided in the applicable
Prospectus Supplement, the Indenture does not limit the incurrence or issuance
of other secured or unsecured debt of the Corporation, including Senior
Indebtedness, whether under the Indenture, any other existing indenture or any
other indenture that the Corporation may enter into in the future or otherwise.
See "-- Subordination" and the applicable Prospectus Supplement relating to any
offering of Preferred Securities or Junior Subordinated Debentures.
    
 
     The Junior Subordinated Debentures will be issuable in one or more series
pursuant to an indenture supplemental to the Indenture or a resolution of the
Corporation's Board of Directors or a committee thereof.
 
     The applicable Prospectus Supplement will describe the following terms of
the Junior Subordinated Debentures: (1) the title of the Junior Subordinated
Debentures; (2) any limit upon the aggregate principal amount of the Junior
Subordinated Debentures; (3) the date or dates on which the principal of the
Junior Subordinated Debentures is payable (the "Stated Maturity") or the method
of determination thereof; (4) the rate or rates, if any, at which the Junior
Subordinated Debentures shall bear interest, the dates on which any such
interest shall be payable (the "Interest Payment Dates"), the right, if any, of
the Corporation to defer or extend an Interest Payment Date,
 
                                       12
<PAGE>   43
 
   
and the record dates for any interest payable on any Interest Payment Date (the
"Regular Record Dates") or the method by which any of the foregoing shall be
determined; (5) the place or places where, subject to the terms of the Indenture
as described below under "-- Payment and Paying Agents," the principal of and
premium, if any, and interest on the Junior Subordinated Debentures will be
payable and where, subject to the terms of the Indenture as described below
under "-- Denominations, Registration and Transfer," the Junior Subordinated
Debentures may be presented for registration of transfer or exchange and the
place or places where notices and demands to or upon the Corporation in respect
of the Junior Subordinated Debentures and the Indentures may be made ("Place of
Payment"); (6) any period or periods within which, or date or dates on which,
the price or prices at which and the terms and conditions upon which Junior
Subordinated Debentures may be redeemed, in whole or in part, at the option of
the Corporation or a holder thereof; (7) the obligation or the right, if any, of
the Corporation or a holder thereof to redeem, purchase or repay the Junior
Subordinated Debentures and the period or periods within which, the price or
prices at which, the currency or currencies (including currency unit or units)
in which and the other terms and conditions upon which the Junior Subordinated
Debentures shall be redeemed, repaid or purchased, in whole or in part, pursuant
to such obligation; (8) the denominations in which any Junior Subordinated
Debentures shall be issuable if other than denominations of $25 and any integral
multiple thereof; (9) if other than in U.S. Dollars, the currency or currencies
(including currency unit or units) in which the principal of (and premium, if
any) and interest, if any, on the Junior Subordinated Debentures shall be
payable, or in which the Junior Subordinated Debentures shall be denominated;
(10) any additions, modifications or deletions in the events of default under
the Indenture or covenants of the Corporation specified in the Indenture with
respect to the Junior Subordinated Debentures; (11) if other than the principal
amount thereof, the portion of the principal amount of Junior Subordinated
Debentures that shall be payable upon declaration of acceleration of the
maturity thereof; (12) any additions or changes to the Indenture with respect to
a series of Junior Subordinated Debentures as shall be necessary to permit or
facilitate the issuance of such series in bearer form, registrable or not
registrable as to principal, and with or without interest coupons; (13) any
index or indices used to determine the amount of payments of principal of and
premium, if any, on the Junior Subordinated Debentures and the manner in which
such amounts will be determined; (14) the terms and conditions relating to the
issuance of a temporary Global Security representing all of the Junior
Subordinated Debentures of such series and the exchange of such temporary Global
Security for definitive Junior Subordinated Debentures of such series; (15)
subject to the terms described herein under "-- Global Junior Subordinated
Debentures," whether the Junior Subordinated Debentures of the series shall be
issued in whole or in part in the form of one or more Global Securities and, in
such case, the depositary for such Global Securities, which depositary shall be
a clearing agency registered under the Exchange Act; (16) the appointment of any
paying agent or agents; (17) the terms and conditions of any obligation or right
of the Corporation or a holder to convert or exchange the Junior Subordinated
Debentures into Preferred Securities; (18) the form of Trust Agreement and
Guarantee Agreement, if applicable; and (19) any other terms of the Junior
Subordinated Debentures not inconsistent with the provisions of the Indenture.
    
 
     Junior Subordinated Debentures may be sold at a substantial discount below
their stated principal amount, bearing no interest or interest at a rate which
at the time of issuance is below market rates. Certain United States federal
income tax consequences and special considerations applicable to any such Junior
Subordinated Debentures will be described in the applicable Prospectus
Supplement.
 
     If the purchase price of any of the Junior Subordinated Debentures is
payable in one or more foreign currencies or currency units or if any Junior
Subordinated Debentures are denominated in one or more foreign currencies or
currency units or if the principal of, premium, if any, or interest on any
Junior Subordinated Debentures is payable in one or more foreign currencies or
currency units, the restrictions, elections, certain United States federal
income tax consequences, specific terms

and other information with respect to such series of Junior Subordinated
Debentures and such foreign currency or currency units will be set forth in the
applicable Prospectus Supplement.
 
     If any index is used to determine the amount of payments of principal of,
premium, if any, or interest on any series of Junior Subordinated Debentures,
special United States federal income tax, accounting and other considerations
applicable thereto will be described in the applicable Prospectus Supplement.
 
DENOMINATIONS, REGISTRATION AND TRANSFER
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Junior Subordinated Debentures will be issuable only in registered form without
coupons in denominations of $25 and any integral multiple thereof. Junior
Subordinated Debentures of any series will be exchangeable for other Junior
Subordinated Debentures of the same issue and series, of any authorized
denominations, of a like aggregate principal amount, of the same original issue
date and stated maturity and bearing the same interest rate.
 
     Junior Subordinated Debentures may be presented for exchange as provided
above, and may be presented for registration of transfer (with the form of
transfer endorsed thereon, or a satisfactory written instrument of transfer,
duly executed), at the office of the appropriate securities registrar or at the
office of any transfer agent designated by the Corporation for such purpose with
respect to any series of Junior Subordinated Debentures and referred to in the
applicable Prospectus Supplement, without service charge and upon payment of any
taxes and other governmental charges as described in the Indenture. The
Corporation will appoint the Trustee as securities registrar under the
Indenture. If the applicable Prospectus Supplement refers to any transfer agents
(in addition to the securities registrar) initially designated by the
Corporation with respect to any series of Junior Subordinated Debentures, the
Corporation may at any time rescind the designation of any such transfer agent
or approve a change in the location through which any such transfer agent acts,
provided that the Corporation maintains a transfer agent in each place of
payment for such series. The Corporation may at any time designate additional
transfer agents with respect to any series of Junior Subordinated Debentures.
 
   
     In the event of any redemption, neither the Corporation nor the Debenture
Trustee shall be required to (i) issue, register the transfer of or exchange
Junior Subordinated Debentures of any series during a period beginning at the
opening of business 15 days before the mailing of a notice of redemption of
Junior Subordinated Debentures of that series and ending at the close of
business on the day of such mailing of the relevant notice of redemption or (ii)
transfer or exchange any Junior Subordinated Debentures selected for redemption,
except, in the case of any Junior Subordinated Debentures being redeemed in
part, any portion thereof not to be redeemed.
    
 
GLOBAL JUNIOR SUBORDINATED DEBENTURES
 
     The Junior Subordinated Debentures of a series may be issued in whole or in
part in the form of one or more Global Junior Subordinated Debentures that will
be deposited with, or on behalf of, a depositary (the "Depositary") identified
in the Prospectus Supplement relating to such series. Global Junior Subordinated
Debentures may be issued only in fully registered form and in either temporary
or permanent form. Unless and until it is exchanged in whole or in part for the
individual Junior Subordinated Debentures represented thereby, a Global Junior
Subordinated Debenture may not be transferred except as a whole by the
Depositary for such Global Junior Subordinated Debenture to a nominee of such
Depositary or by a nominee of such Depositary to such Depositary or another
nominee of such Depositary or by the Depositary or any nominee to a successor
Depositary or any nominee of such successor.
 
     The specific terms of the depositary arrangement with respect to a series
of Junior Subordinated Debentures will be described in the Prospectus Supplement
relating to such series. The
 
                                       14
<PAGE>   45
 
Corporation anticipates that the following provisions will generally apply to
depositary arrangements.
 
     Upon the issuance of a Global Junior Subordinated Debenture, and the
deposit of such Global Junior Subordinated Debenture with or on behalf of the
Depositary, the Depositary for such Global Junior Subordinated Debenture or its
nominee will credit, on its book-entry registration and transfer system, the
respective principal amounts of the individual Junior Subordinated Debentures
represented by such Global Junior Subordinated Debenture to the accounts of
persons that have accounts with such Depositary ("Participants"). Such accounts
shall be designated by the dealers, underwriters or agents with respect to such
Junior Subordinated Debentures or by the Corporation if such Junior Subordinated
Debentures are offered and sold directly by the Corporation. Ownership of
beneficial interests in a Global Junior Subordinated Debenture will be limited
to Participants or persons that may hold interests through Participants.
Ownership of beneficial interests in such Global Junior Subordinated Debenture
will be shown on, and the transfer of that ownership will be effected only
through, records maintained by the applicable Depositary or its nominee (with
respect to interests of Participants) and the records of Participants (with
respect to interests of persons who hold through Participants). The laws of some
states require that certain purchasers of securities take physical delivery of
such securities in definitive form. Such limits and such laws may impair the
ability to transfer beneficial interests in a Global Junior Subordinated
Debenture.
 
     So long as the Depositary for a Global Junior Subordinated Debenture, or
its nominee, is the registered owner of such Global Junior Subordinated
Debenture, such Depositary or such nominee, as the case may be, will be
considered the sole owner or holder of the Junior Subordinated Debentures
represented by such Global Junior Subordinated Debenture for all purposes under
the Indenture governing such Junior Subordinated Debentures. Except as provided
below, owners of beneficial interests in a Global Junior Subordinated Debenture
will not be entitled to have any of the individual Junior Subordinated
Debentures of the series represented by such Global Junior Subordinated
Debenture registered in their names, will not receive or be entitled to receive
physical delivery of any such Junior Subordinated Debentures of such series in
definitive form and will not be considered the owners or holders thereof under
the Indenture.
 
     Payments of principal of (and premium, if any) and interest on individual
Junior Subordinated Debentures represented by a Global Junior Subordinated
Debenture registered in the name of a Depositary or its nominee will be made to
the Depositary or its nominee, as the case may be, as the registered owner of
the Global Junior Subordinated Debenture representing such Junior Subordinated
Debentures. None of the Corporation, the Debenture Trustee, any Paying Agent, or
the Securities Registrar for such Junior Subordinated Debentures will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests of the Global Junior
Subordinated Debenture representing such Junior Subordinated Debentures or for
maintaining, supervising or reviewing any records relating to such beneficial
ownership interests.
 
     The Corporation expects that the Depositary for a series of Junior
Subordinated Debentures or its nominee, upon receipt of any payment of
principal, premium, if any, or interest in respect of a permanent Global Junior
Subordinated Debenture representing any of such Junior Subordinated Debentures,
immediately will credit Participants' accounts with payments in amounts
proportionate to their respective beneficial interest in the principal amount of
such Global Junior Subordinated Debenture for such Junior Subordinated
Debentures as shown on the records of such Depositary or its nominee. The
Corporation also expects that payments by Participants to owners of beneficial
interests in such Global Junior Subordinated Debenture held through such
Participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers in bearer
form or registered in "street name." Such payments will be the responsibility of
such Participants.
 
                                       15
<PAGE>   46
 
     Unless otherwise specified in the applicable Prospectus Supplement, if a
Depositary for a series of Junior Subordinated Debentures is at any time
unwilling, unable or ineligible to continue as depositary and a successor
depositary is not appointed by the Corporation within 90 days, the Corporation
will issue individual Junior Subordinated Debentures of such series in exchange
for the Global Junior Subordinated Debenture representing such series of Junior
Subordinated Debentures. In addition, the Corporation may at any time and in its
sole discretion, subject to any limitations described in the Prospectus
Supplement relating to such Junior Subordinated Debentures, determine not to
have any Junior Subordinated Debentures of such series represented by one or
more Global Junior Subordinated Debentures and, in such event, will issue
certificated Junior Subordinated Debentures of such series in exchange for the
Global Junior Subordinated Debenture. Further, if the Corporation so specifies
with respect to the Junior Subordinated Debentures of a series, an owner of a
beneficial interest in a Global Junior Subordinated Debenture representing
Junior Subordinated Debentures of such series may, on terms acceptable to the
Corporation, the Debenture Trustee and the Depositary for such Global Junior
Subordinated Debenture, receive certificated Junior Subordinated Debentures of
such series in exchange for such beneficial interests, subject to any
limitations described in the Prospectus Supplement relating to such Junior
Subordinated Debentures. In any such instance, an owner of a beneficial interest
in a Global Junior Subordinated Debenture will be entitled to physical delivery
of certificated Junior Subordinated Debentures of the series represented by such
Global Junior Subordinated Debenture equal in principal amount to such
beneficial interest and to have such Junior Subordinated Debentures registered
in its name. Individual Junior Subordinated Debentures of such series so issued
will be issued in denominations, unless otherwise specified by the Corporation,
of $25 and integral multiples thereof.
 
PAYMENT AND PAYING AGENTS
 
   
     Unless otherwise indicated in the applicable Prospectus Supplement, payment
of principal of (and premium, if any) and any interest on Junior Subordinated
Debentures will be made at the office of the Debenture Trustee in The City of
New York or at the office of such paying agent or paying agents as the
Corporation may designate from time to time in the applicable Prospectus
Supplement, except that at the option of the Corporation payment of any interest
may be made (i) except in the case of Global Junior Subordinated Debentures, by
check mailed to the address of the person entitled thereto as such address shall
appear in the securities register or (ii) by wire transfer or direct deposit to
an account maintained by the person entitled thereto as specified in the
securities register, provided that proper transfer instructions have been
received by the Regular Record Date. Unless otherwise indicated in the
applicable Prospectus Supplement, payment of any interest on Junior Subordinated
Debentures will be made to the person in whose name such Junior Subordinated
Debenture is registered at the close of business on the Regular Record Date for
such interest, except in the case of defaulted interest. The Corporation may at
any time designate additional paying agents or rescind the designation of any
paying agent; however the Corporation will at all times be required to maintain
a paying agent in each place of payment for each series of Junior Subordinated
Debentures.
    
 
     Any moneys deposited with the Debenture Trustee or any paying agent, or
then held by the Corporation in trust, for the payment of the principal of (and
premium, if any) or interest on any Junior Subordinated Debenture and remaining
unclaimed for two years after such principal (and premium, if any) or interest
has become due and payable shall, at the request of the Corporation, be repaid
to the Corporation and the holder of such Junior Subordinated Debenture shall
thereafter look, as a general unsecured creditor, only to the Corporation for
payment thereof.
 
OPTION TO DEFER INTEREST PAYMENTS
 
     If provided in the applicable Prospectus Supplement, the Corporation will
have the right at any time and from time to time during the term of any series
of Junior Subordinated Debentures to defer
 
                                       16
<PAGE>   47
 
payment of interest for up to such number of consecutive interest payment
periods as may be specified in the applicable Prospectus Supplement (each, an
"Extension Period"), subject to the terms, conditions and covenants, if any,
specified in such Prospectus Supplement, provided that such Extension Period may
not extend beyond the Stated Maturity of such series of Junior Subordinated
Debentures. Certain United States federal income tax consequences and special
considerations applicable to any such Junior Subordinated Debentures will be
described in the applicable Prospectus Supplement.
 
REDEMPTION
 
     Unless otherwise indicated in the applicable Prospectus Supplement, Junior
Subordinated Debentures will not be subject to any sinking fund.
 
   
     Unless otherwise indicated in the applicable Prospectus Supplement, the
Corporation may, at its option, redeem the Junior Subordinated Debentures of any
series in whole at any time or in part from time to time. If the Junior
Subordinated Debentures of any series are so redeemable only on or after a
specified date or upon the satisfaction of additional conditions, the applicable
Prospectus Supplement will specify such date or describe such conditions. Junior
Subordinated Debentures in denominations larger than $25 may be redeemed in part
but only in integral multiples of $25. Except as otherwise specified in the
applicable Prospectus Supplement, the redemption price for any Junior
Subordinated Debenture so redeemed shall equal any accrued and unpaid interest
thereon to the redemption date, plus 100% of the principal amount thereof. The
Corporation has committed to the Reserve Bank that it will not cause any such
redemption without having received the prior approval of the Federal Reserve to
do so, if then required under applicable Federal Reserve capital guidelines or
policies.
    
 
   
     Except as otherwise specified in the applicable Prospectus Supplement, if a
Debenture Tax Event (as defined below) in respect of a series of Junior
Subordinated Debentures or a Capital Treatment Event (as defined herein) shall
occur and be continuing, the Corporation may, at its option, redeem such series
of Junior Subordinated Debentures in whole (but not in part) at any time within
90 days following the occurrence of such Debenture Tax Event or Capital
Treatment Event, at a redemption price equal to 100% of the principal amount of
such Junior Subordinated Debentures then outstanding plus accrued and unpaid
interest to the date fixed for redemption. The Corporation has committed to the
Reserve Bank that it will not cause any such redemption without having received
the prior approval of the Federal Reserve to do so, if then required under
applicable Federal Reserve capital guidelines or policies.
    
 
   
     "Tax Event" with respect to Junior Subordinated Debentures held by an
Issuer means the receipt by the Issuer of a series of Preferred Securities of an
opinion of counsel experienced in such matters to the effect that, as a result
of any amendment to, or change (including any announced proposed change) in, the
laws (or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any
official administrative pronouncement or judicial decision interpreting or
applying such laws or regulations, which amendment or change is effective or
which proposed change, pronouncement or decision is announced on or after the
date of issuance of such Preferred Securities under the Trust Agreement, there
is more than an insubstantial risk that (i) such Issuer is, or will be within 90
days of the date of such opinion, subject to United States federal income tax
with respect to income received or accrued on the corresponding series of
Corresponding Junior Subordinated Debentures, (ii) interest payable by the
Corporation on such series of Corresponding Junior Subordinated Debentures is
not, or within 90 days of the date of such opinion, will not be, deductible by
the Corporation, in whole or in part, for United States federal income tax
purposes, or (iii) such Issuer is, or will be within 90 days of the date of such
opinion, subject to more than a de minimis amount of other taxes, duties or
other governmental charges. With respect to Junior Subordinated Debentures not
held by an Issuer, "Tax Event" means the receipt by the Corporation of an
opinion of counsel experienced in such matters to the effect that, as a result
of any amendment to, or change (including any
    
 
                                       17
<PAGE>   48
 
announced proposed change) in, the laws (or any regulations thereunder) of the
United States or any political subdivision or taxing authority thereof or
therein, or as a result of any official administrative pronouncement or judicial
decision interpreting or applying such laws or regulations, which amendment or
change is effective or which proposed change, pronouncement or decision is
announced on or after the date of issuance of the applicable series of Junior
Subordinated Debentures under the Indenture, there is more than an insubstantial
risk that interest payable by the Corporation on such series of Junior
Subordinated Debentures is not, or within 90 days of the date of such opinion
will not be, deductible by the Corporation, in whole or in part, for United
States federal income tax purposes.
 
     A "Capital Treatment Event" means the reasonable determination by the
Corporation that, as a result of any amendment to, or change (including any
proposed change) in, the laws (or any regulations thereunder) of the United
States or any political subdivision thereof or therein, or as a result of any
official or administrative pronouncement or action or judicial decision
interpreting or applying such laws or regulations, which amendment or change is
effective or such proposed change, pronouncement, action or decision is
announced on or after the date of issuance of the applicable Preferred
Securities under the applicable Trust Agreement, there is more than an
insubstantial risk that the Corporation will not be entitled to treat an amount
equal to the Liquidation Amount of the applicable Preferred Securities as "Tier
I Capital" (or the then equivalent thereof) for purposes of the capital adequacy
guidelines of the Federal Reserve, as then in effect and applicable to the
Corporation.
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of Junior Subordinated
Debentures to be redeemed at its registered address. Unless the Corporation
defaults in payment of the redemption price, on and after the redemption date
interest ceases to accrue on such Junior Subordinated Debentures or portions
thereof called for redemption.
 
RESTRICTIONS ON CERTAIN PAYMENTS
 
     The Corporation will also covenant, as to each series of Junior
Subordinated Debentures, that it will not, and will not permit any subsidiary of
the Corporation to, (i) declare or pay any dividends or distributions on, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of
the Corporation's capital stock, (ii) make any payment of principal, interest or
premium, if any, on or repay or repurchase or redeem any debt securities of the
Corporation (including other series of Junior Subordinated Debentures) that rank
pari passu with or junior in interest to the Junior Subordinated Debentures or
(iii) make any guarantee payments with respect to any guarantee by the
Corporation of the debt securities of any subsidiary of the Corporation if such
guarantee ranks pari passu with or junior in interest to the Junior Subordinated
Debentures (other than (a) dividends or distributions in capital stock of the
Corporation, (b) any declaration of a dividend in connection with the
implementation of a stockholders' rights plan, or the redemption or repurchase
of any such rights pursuant thereto, (c) payments under any Guarantee with
respect to the series of Related Preferred Securities and (d) purchases of
common stock related to the issuance of common stock or rights or options under
any of the Corporation's benefit plans for its directors, officers, employees or
other persons within the definition of "employee" for purposes of a registration
of shares for an employee benefit plan of the Corporation, related to the
issuance of common stock or rights under a dividend reinvestment and stock
purchase plan, or related to the issuance of common stock (or securities
convertible into or exchangeable for common stock) as consideration in an
acquisition transaction) if at such time (i) there shall have occurred any event
of which the Corporation has actual knowledge (a) that with the giving of notice
or the lapse of time, or both, would constitute an "Event of Default" under the
Indenture with respect to the Junior Subordinated Debentures of such series and
(b) in respect of which the Corporation shall not have taken reasonable steps to
cure, (ii) if such Junior Subordinated Debentures are held by an Issuer of a
series of Related Preferred Securities, the Corporation shall be in default with
respect to its payment of any obligations under
 
                                       18
<PAGE>   49
 
   
the Guarantee relating to such Related Preferred Securities or (iii) the
Corporation shall have given notice of its selection of an Extension Period as
provided in the Indenture with respect to the Junior Subordinated Debentures of
such series and shall not have rescinded such notice, and such Extension Period,
or any extension thereof, shall be continuing.
    
 
MODIFICATION OF INDENTURE
 
     From time to time the Corporation and the Debenture Trustee may, without
the consent of the holders of any series of Junior Subordinated Debentures,
amend, waive or supplement the Indenture for specified purposes, including,
among other things, curing ambiguities, defects or inconsistencies (provided
that any such action does not materially adversely affect the interest of the
holders of any series of Junior Subordinated Debentures or, in the case of
Corresponding Junior Subordinated Debentures, the holders of the Related
Preferred Securities so long as they remain outstanding) and qualifying, or
maintaining the qualification of, the Indenture under the Trust Indenture Act.
The Indenture contains provisions permitting the Corporation and the Debenture
Trustee, with the consent of the holders of not less than a majority in
principal amount of each outstanding series of Junior Subordinated Debentures
affected, to modify the Indenture in a manner adversely affecting the rights of
the holders of such series of the Junior Subordinated Debentures in any material
respect; provided, that no such modification may, without the consent of the
holder of each outstanding Junior Subordinated Debenture so affected, (i) change
the Stated Maturity of any series of Junior Subordinated Debentures (except as
otherwise specified in the applicable Prospectus Supplement), or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon or (ii) reduce the percentage of principal amount of Junior
Subordinated Debentures of any series, the holders of which are required to
consent to any such modification of the Indenture, provided further that, in the
case of Corresponding Junior Subordinated Debentures, so long as any Related
Preferred Securities remain outstanding, (a) no such modification may be made
that adversely affects the holders of such Preferred Securities in any material
respect, and no termination of the Indenture may occur, and no waiver of any
event of default or compliance with any covenant under the Indenture may be
effective, without the prior consent of the holders of at least a majority of
the aggregate Liquidation Amount of all outstanding Related Preferred Securities
affected unless and until the principal of the Corresponding Junior Subordinated
Debentures and all accrued and unpaid interest thereon have been paid in full
and certain other conditions have been satisfied, and (b) where a consent under
the Indenture would require the consent of each holder of Corresponding Junior
Subordinated Debentures, no such consent shall be given by the Property Trustee
without the prior consent of each holder of Related Preferred Securities.
 
     In addition, the Corporation and the Debenture Trustee may execute, without
the consent of any holder of Junior Subordinated Debentures, any supplemental
Indenture for the purpose of creating any new series of Junior Subordinated
Debentures.
 
DEBENTURE EVENTS OF DEFAULT
 
     The Indenture provides that any one or more of the following described
events with respect to a series of Junior Subordinated Debentures that has
occurred and is continuing constitutes a "Debenture Event of Default" with
respect to such series of Junior Subordinated Debentures:
 
          (i) failure for 30 days to pay any interest on such series of Junior
     Subordinated Debentures when due (subject to the deferral of any interest
     payment in the case of an Extension Period); or
 
          (ii) failure to pay any principal or premium, if any, on such series
     of Junior Subordinated Debentures when due whether at maturity or upon
     redemption; or
 
          (iii) failure to observe or perform in any material respect certain
     other covenants contained in the Indenture for 90 days after written notice
     to the Corporation from the Debenture Trustee
 
                                       19
<PAGE>   50
 
     or the holders of at least 25% in aggregate outstanding principal amount of
     such affected series of outstanding Junior Subordinated Debentures; or
 
          (iv) certain events in bankruptcy, insolvency or reorganization of the
     Corporation.
 
   
     The holders of a majority in aggregate outstanding principal amount of
Junior Subordinated Debentures of each series affected have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Debenture Trustee. Upon certain events of bankruptcy, insolvency or
reorganization of the Corporation constituting a Debenture Event of Default, the
principal amount of all outstanding Junior Subordinated Debentures (or such
portions of the principal amount as may be specified in the applicable
Prospectus Supplement) shall automatically become immediately due and payable.
The Debenture Trustee or the holders of not less than 25% in aggregate
outstanding principal amount of Junior Subordinated Debentures of each series
affected may declare the principal (or such portion of the principal amount as
may be specified in the applicable Prospectus Supplement) due and payable
immediately upon any other Debenture Event of Default, and, in the case of
Corresponding Junior Subordinated Debentures, should the Debenture Trustee or
such holders of such Corresponding Junior Subordinated Debentures fail to make
such declaration, the holders of at least 25% in aggregate Liquidation Amount of
the Related Preferred Securities shall have such right. The holders of a
majority in aggregate outstanding principal amount of Junior Subordinated
Debentures of each series affected may annul such declaration. In the case of
Corresponding Junior Subordinated Debentures, should the holders of such
Corresponding Junior Subordinated Debentures fail to annul such declaration and
waive such default, the holders of a majority in aggregate Liquidation Amount of
the Related Preferred Securities affected shall have such right.
    
 
     The holders of a majority in aggregate outstanding principal amount of each
series of the Junior Subordinated Debentures affected thereby may, on behalf of
the holders of all the Junior Subordinated Debentures, waive any default, except
a default in the payment of principal or interest (unless such default has been
cured and a sum sufficient to pay all matured installments of interest and
principal due otherwise than by acceleration has been deposited with the
Debenture Trustee) or a default in respect of a covenant or provision which
under the Indenture cannot be modified or amended without the consent of the
holder of each outstanding Junior Subordinated Debenture. In the case of
Corresponding Junior Subordinated Debentures, should the holders of such
Corresponding Junior Subordinated Debentures fail to waive such default, the
holders of a majority in aggregate Liquidation Amount of the Related Preferred
Securities affected shall have such right. The Corporation is required to file
annually with the Debenture Trustee a certificate as to whether or not the
Corporation is in compliance with all the conditions and covenants applicable to
it under the Indenture.
 
     In case a Debenture Event of Default shall occur and be continuing as to a
series of Corresponding Junior Subordinated Debentures, the Property Trustee
will have the right to declare the principal of and the interest on such
Corresponding Junior Subordinated Debentures, and any other amounts payable
under the Indenture, to be forthwith due and payable and to enforce its other
rights as a creditor with respect to such Corresponding Junior Subordinated
Debentures.
 
ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF PREFERRED SECURITIES
 
     If a Debenture Event of Default with respect to a series of Corresponding
Junior Subordinated Debentures has occurred and is continuing and such event is
attributable to the failure of the Corporation to pay interest or principal on
such Corresponding Junior Subordinated Debentures on the date such interest or
principal is due and payable, a holder of Preferred Securities may institute a
legal proceeding directly against the Corporation for enforcement of payment to
such holder of the principal of or interest on such Corresponding Junior
Subordinated Debentures having a principal amount equal to the aggregate
Liquidation Amount of the Related Preferred Securities of such holder (a "Direct
Action"). The Corporation may not amend the Indenture to remove the foregoing
 
                                       20
<PAGE>   51
 
right to bring a Direct Action without the prior written consent of the holders
of all of the Preferred Securities outstanding. If the right to bring a Direct
Action is removed, the applicable Issuer may become subject to the reporting
obligations under the Exchange Act. The Corporation shall have the right under
the Indenture to set-off any payment made to such holder of Preferred Securities
by the Corporation in connection with a Direct Action.
 
     The holders of the Preferred Securities will not be able to exercise
directly any remedies other than those set forth in the preceding paragraph
available to the holders of the Junior Subordinated Debentures unless there
shall have been an event of default under the Trust Agreement. See "Description
of Preferred Securities -- Events of Default; Notice".
 
CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS
 
     The Indenture provides that the Corporation shall not consolidate with or
merge into any other Person or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, and no Person shall
consolidate with or merge into the Corporation or convey, transfer or lease its
properties and assets substantially as an entirety to the Corporation, unless
(i) in case the Corporation consolidates with or merges into another Person or
conveys or transfers its properties and assets substantially as an entirety to
any Person, the successor Person is organized under the laws of the United
States or any state or the District of Columbia, and such successor Person
expressly assumes the Corporation's obligations on the Junior Subordinated
Debentures issued under the Indenture; (ii) immediately after giving effect
thereto, no Debenture Event of Default, and no event which, after notice or
lapse of time or both, would become a Debenture Event of Default, shall have
occurred and be continuing; (iii) in the case of Corresponding Junior
Subordinated Debentures, such transaction is permitted under the related Trust
Agreement and Guarantee and does not give rise to any breach or violation of the
related Trust Agreement or Guarantee, and (iv) certain other conditions as
prescribed by the Indenture are met.
 
     The general provisions of the Indenture do not afford holders of the Junior
Subordinated Debentures protection in the event of a highly leveraged or other
transaction involving the Corporation that may adversely affect holders of the
Junior Subordinated Debentures.
 
SATISFACTION AND DISCHARGE
 
     The Indenture provides that when, among other things, all Junior
Subordinated Debentures not previously delivered to the Debenture Trustee for
cancellation (i) have become due and payable or (ii) will become due and payable
at their Stated Maturity within one year, and the Corporation deposits or causes
to be deposited with the Debenture Trustee funds, in trust, for the purpose and
in an amount in the currency or currencies in which the Junior Subordinated
Debentures are payable sufficient to pay and discharge the entire indebtedness
on the Junior Subordinated Debentures not previously delivered to the Debenture
Trustee for cancellation, for the principal (and premium, if any) and interest
to the date of the deposit or to the Stated Maturity, as the case may be, then
the Indenture will cease to be of further effect (except as to the Corporation's
obligations to pay all other sums due pursuant to the Indenture and to provide
the officers' certificates and opinions of counsel described therein), and the
Corporation will be deemed to have satisfied and discharged the Indenture.
 
CONVERSION OR EXCHANGE
 
     If and to the extent indicated in the applicable Prospectus Supplement, the
Junior Subordinated Debentures of any series may be convertible or exchangeable
into Junior Subordinated Debentures of another series or into Preferred
Securities of another series. The specific terms on which Junior Subordinated
Debentures of any series may be so converted or exchanged will be set forth in
the applicable Prospectus Supplement. Such terms may include provisions for
conversion or exchange, either mandatory, at the option of the holder, or at the
option of the Corporation, in which case the
 
                                       21
<PAGE>   52
 
number of shares of Preferred Securities or other securities to be received by
the holders of Junior Subordinated Debentures would be calculated as of a time
and in the manner stated in the applicable Prospectus Supplement.
 
SUBORDINATION
 
   
     The Junior Subordinated Debentures shall be subordinate and junior in right
of payment, to the extent set forth in the Indenture, to all Senior Indebtedness
(as defined below) of the Corporation. In the event that the Corporation shall
default in the payment of any principal, premium, if any, or interest, if any,
on any Senior Indebtedness when the same becomes due and payable, whether at
maturity or at a date fixed for prepayment or by declaration of acceleration or
otherwise, then, unless and until such default shall have been cured or waived
or shall have ceased to exist or all Senior Indebtedness shall have been paid,
no direct or indirect payment (in cash, property, securities, by set-off or
otherwise) shall be made or agreed to be made for principal, premium, if any, or
interest, if any, on the Junior Subordinated Debentures, or in respect of any
redemption, repayment, retirement, purchase or other acquisition of any of the
Junior Subordinated Debentures.
    
 
     As used herein, "Senior Debt" means any obligation of the Corporation to
its creditors, whether now outstanding or subsequently incurred, other than any
obligation as to which, in the instrument creating or evidencing the obligation
or pursuant to which the obligation is outstanding, it is provided that such
obligation is not Senior Debt. As used herein, "Senior Subordinated Debt" means
any obligation of the Corporation to its creditors, whether now outstanding or
subsequently incurred, where the instrument creating or evidencing the
obligation or pursuant to which the obligation is outstanding, provides that it
is subordinate and junior in right of payment to Senior Debt. Senior
Subordinated Debt includes the Corporation's outstanding subordinated debt
securities and any subordinated debt securities issued in the future with
substantially similar subordination terms and does not include the Junior
Subordinated Debentures. Senior Debt does not include Senior Subordinated Debt
or the Junior Subordinated Debentures.
 
     As used herein, "Senior Indebtedness" shall include (i) Senior Debt (but
excluding trade accounts payable and accrued liabilities arising in the ordinary
course of business) and (ii) the Allocable Amounts (as defined below) of Senior
Subordinated Debt. As of September 30, 1996, the Corporation had approximately
$160 million of Senior Indebtedness outstanding.
 
     As used herein, "Allocable Amounts," when used with respect to any Senior
Subordinated Debt, means the amount necessary to pay all principal of (and
premium, if any) and interest, if any, on such Senior Subordinated Debt in full
less, if applicable, any portion of such amounts which would have been paid to,
and retained by, the holders of such Senior Subordinated Debt (whether as a
result of the receipt of payments by the holders of such Senior Subordinated
Debt from the Corporation or any other obligor thereon or from any holders of,
or trustee in respect of, other indebtedness that is subordinate and junior in
right of payment to such Senior Subordinated Debt pursuant to any provision of
such indebtedness for the payment over of amounts received on account of such
indebtedness to the holders of such Senior Subordinated Debt) but for the fact
that such Senior Subordinated Debt is subordinate or junior in right of payment
to trade accounts payable or accrued liabilities arising in the ordinary course
of business.
 
     In the event of (i) any insolvency, bankruptcy, receivership, liquidation,
reorganization, readjustment, composition or other similar proceeding relating
to the Corporation, its creditors or its property, (ii) any proceeding for the
liquidation, dissolution or other winding up of the Corporation, voluntary or
involuntary, whether or not involving insolvency or bankruptcy proceedings,
(iii) any assignment by the Corporation for the benefit of creditors or (iv) any
other marshalling of the assets of the Corporation, all Senior Indebtedness
(including any interest thereon accruing after the commencement of any such
proceedings) shall first be paid in full before any payment or distribution,
whether in cash, securities or other property, shall be made on account of the
principal of or premium, if any, or interest, if any, on the Junior Subordinated
Debentures. In such event, any
 
                                       22
<PAGE>   53
 
payment or distribution on account of the principal of or premium, if any, or
interest, if any, on the Junior Subordinated Debentures, whether in cash,
securities or other property (other than securities of the Corporation or any
other corporation provided for by a plan of reorganization or readjustment the
payment of which is subordinate, at least to the extent provided in the
subordination provisions with respect to the Junior Subordinated Debentures, to
the payment of all Senior Indebtedness at the time outstanding, and to any
securities issued in respect thereof under any such plan of reorganization or
readjustment), which would otherwise (but for the subordination provisions) be
payable or deliverable in respect of the Junior Subordinated Debentures shall be
paid or delivered directly to the holders of Senior Indebtedness in accordance
with the priorities then existing among such holders until all Senior
Indebtedness (including any interest thereon accruing after the commencement of
any such proceedings) shall have been paid in full.
 
   
     In the event of any such proceeding, after payment in full of all sums
owing with respect to Senior Indebtedness, the holders of Junior Subordinated
Debentures, together with the holders of any obligations of the Corporation
ranking on a parity with the Junior Subordinated Debentures, shall be entitled
to be paid from the remaining assets of the Corporation the amounts at the time
due and owing on account of unpaid principal of and premium, if any, and
interest, if any, on the Junior Subordinated Debentures and such other
obligations before any payment or other distribution, whether in cash, property
or otherwise, shall be made on account of any capital stock or obligations of
the Corporation ranking junior to the Junior Subordinated Debentures and such
other obligations. If any payment or distribution on account of the principal of
or interest on the Junior Subordinated Debentures of any character or any
security, whether in cash, securities or other property (other than securities
of the Corporation or any other corporation provided for by a plan of
reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in the subordination provisions with respect to the Junior
Subordinated Debentures, to the payment of all Senior Indebtedness at the time
outstanding and to any securities issued in respect thereof under any such plan
of reorganization or readjustment) shall be received by any holder of any Junior
Subordinated Debentures in contravention of any of the terms hereof and before
all the Senior Indebtedness shall have been paid in full, such payment or
distribution or security shall be received in trust for the benefit of, and
shall be paid over or delivered and transferred to, the holders of the Senior
Indebtedness at the time outstanding in accordance with the priorities then
existing among such holders for application to the payment of all Senior
Indebtedness remaining unpaid to the extent necessary to pay all such Senior
Indebtedness in full. By reason of such subordination, in the event of the
insolvency of the Corporation, holders of Senior Indebtedness may receive more,
ratably, and holders of the Junior Subordinated Debentures having a claim
pursuant to such securities may receive less, ratably, than the other creditors
of the Corporation. Such subordination will not prevent the occurrence of any
Debenture Event of Default in respect of the Junior Subordinated Debentures.
    
 
   
     The Indenture provides that the foregoing subordination provisions, insofar
as they relate to any particular issue of Junior Subordinated Debentures, may be
changed prior to such issuance. Any such change would be described in the
applicable Prospectus Supplement.
    
 
   
     The Indenture places no limitation on the amount of additional Senior
Indebtedness that may be incurred by the Corporation. The Corporation expects
from time to time to incur additional indebtedness constituting Senior
Indebtedness.
    
 
GOVERNING LAW
 
     The Indenture and the Junior Subordinated Debentures will be governed by
and construed in accordance with the laws of the State of New York.

INFORMATION CONCERNING THE DEBENTURE TRUSTEE
 
     The Debenture Trustee shall have and be subject to all the duties and
responsibilities specified with respect to an indenture trustee under the Trust
Indenture Act. Subject to such provisions, the Debenture Trustee is under no
obligation to exercise any of the powers vested in it by the Indenture at the
request of any holder of Junior Subordinated Debentures, unless offered
reasonable indemnity by such holder against the costs, expenses and liabilities
which might be incurred thereby. The Debenture Trustee is not required to expend
or risk its own funds or otherwise incur personal financial liability in the
performance of its duties if the Debenture Trustee reasonably believes that
repayment or adequate indemnity is not reasonably assured to it.
 
CORRESPONDING JUNIOR SUBORDINATED DEBENTURES
 
     The Corresponding Junior Subordinated Debentures may be issued in one or
more series of Junior Subordinated Debentures under the Indenture with terms
corresponding to the terms of a series of Related Preferred Securities. In that
event, concurrently with the issuance of each Issuer's Preferred Securities,
such Issuer will invest the proceeds thereof and the consideration paid by the
Corporation for the Common Securities of such Issuer in such series of
Corresponding Junior Subordinated Debentures issued by the Corporation to such
Issuer. Each series of Corresponding Junior Subordinated Debentures will be in
the principal amount equal to the aggregate stated Liquidation Amount of the
Related Preferred Securities and the Common Securities of such Issuer and will
rank pari passu with all other series of Junior Subordinated Debentures. Holders
of the Related Preferred Securities for a series of Corresponding Junior
Subordinated Debentures will have the rights, in connection with modifications
to the Indenture or upon occurrence of Debenture Events of Default, as described
under "-- Modification of Indenture" and " -- Debenture Events of Default,"
unless provided otherwise in the Prospectus Supplement for such Related
Preferred Securities.
 
   
     Unless otherwise specified in the applicable Prospectus Supplement, if a
Tax Event or Capital Treatment Event in respect of an Issuer shall occur and be
continuing, the Corporation may, at its option, redeem the Corresponding Junior
Subordinated Debentures at any time within 90 days of the occurrence of such Tax
Event or Capital Treatment Event, in whole but not in part, subject to the
provisions of the Indenture and whether or not such Corresponding Junior
Subordinated Debentures are then otherwise redeemable at the option of the
Corporation. The redemption price for any Corresponding Junior Subordinated
Debentures shall be equal to 100% of the principal amount of such Corresponding
Junior Subordinated Debentures then outstanding plus accrued and unpaid interest
to the date fixed for redemption. The Corporation has committed to the Reserve
Bank that it will not cause any such redemption without having received the
prior approval of the Federal Reserve to do so, if then required under
applicable Federal Reserve capital guidelines or policies. For so long as the
applicable Issuer is the holder of all the outstanding Corresponding Junior
Subordinated Debentures of such series, the proceeds of any such redemption will
be used by the Issuer to redeem the corresponding Trust Securities in accordance
with their terms. The Corporation may not redeem a series of Corresponding
Junior Subordinated Debentures in part unless all accrued and unpaid interest
has been paid in full on all outstanding Corresponding Junior Subordinated
Debentures of such series for all interest periods terminating on or prior to
the Redemption Date.
    
 
     The Corporation will covenant in the Indenture, as to each series of
Corresponding Junior Subordinated Debentures, that if and so long as (i) the
Issuer of the related series of Trust Securities is the holder of all such
Corresponding Junior Subordinated Debentures, (ii) a Tax Event in respect of
such Issuer has occurred and is continuing and (iii) the Corporation has
elected, and has not revoked such election, to pay Additional Sums (as defined
under "Description of Preferred Securities -- Redemption or Exchange") in
respect of such Trust Securities, the Corporation will pay to such Issuer such
Additional Sums. The Corporation will also covenant, as to each series of
Corresponding Junior Subordinated Debentures, (i) to maintain directly or
indirectly 100% owner-
 
                                       24
<PAGE>   55
 
   
ship of the Common Securities of the Issuer to which such Corresponding Junior
Subordinated Debentures have been issued, provided that certain successors which
are permitted pursuant to the Indenture may succeed to the Corporation's
ownership of the Common Securities, (ii) not to voluntarily terminate, wind up
or liquidate any Issuer, except (a) in connection with a distribution of
Corresponding Junior Subordinated Debentures to the holders of the Preferred
Securities in exchange therefor upon liquidation of such Issuer, or (b) in
connection with certain mergers, consolidations or amalgamations permitted by
the related Trust Agreement, in either such case, if so specified in the
applicable Prospectus Supplement upon prior approval of the Federal Reserve if
then so required under applicable capital guidelines or policies, and (iii) to
use its reasonable efforts, consistent with the terms and provisions of the
related Trust Agreement, to cause such Issuer to be classified as a grantor
trust and not as an association taxable as a corporation for United States
federal income tax purposes.
    
 
                      DESCRIPTION OF PREFERRED SECURITIES
 
   
     Pursuant to the terms of the Trust Agreement for each Issuer, the Issuer
Trustees on behalf of such Issuer will issue the Preferred Securities and the
Common Securities. The Preferred Securities of a particular issue will represent
beneficial ownership interests in the Issuer and the holders thereof will be
entitled to a preference in certain circumstances with respect to Distributions
and amounts payable on redemption or liquidation over the Common Securities of
such Issuer, as well as other benefits as described in the corresponding Trust
Agreement. This summary of certain provisions of the Preferred Securities and
each Trust Agreement, which summarizes material terms thereof, does not purport
to be complete and is subject to, and is qualified in its entirety by reference
to, all the provisions of each Trust Agreement, including the definitions
therein of certain terms, and the Trust Indenture Act, to each of which
reference is hereby made. Wherever particular defined terms of a Trust Agreement
(as amended or supplemented from time to time) are referred to herein or in a
Prospectus Supplement, such defined terms are incorporated herein or therein by
reference. The form of the Trust Agreement has been filed as an exhibit to the
Registration Statement of which this Prospectus forms a part. Each of the
Issuers is a legally separate entity and the assets of one are not available to
satisfy the obligations of any of the others.
    
 
GENERAL
 
   
     The Preferred Securities of an Issuer will rank pari passu, and payments
will be made thereon pro rata, with the Common Securities of that Issuer except
as described under "-- Subordination of Common Securities". Legal title to the
Corresponding Junior Subordinated Debentures will be held by the Property
Trustee in trust for the benefit of the holders of the related Preferred
Securities and Common Securities. Each Guarantee Agreement executed by the
Corporation for the benefit of the holders of an Issuer's Trust Securities (the
"Guarantee") will be a guarantee on a subordinated basis with respect to the
related Trust Securities but will not guarantee payment of Distributions or
amounts payable on redemption or liquidation of such Trust Securities when the
related Issuer does not have funds on hand available to make such payments. See
"Description of Guarantees".
    
 
DISTRIBUTIONS
 
     Distributions on the Preferred Securities will be cumulative, will
accumulate from the date of original issuance and will be payable on such dates
as specified in the applicable Prospectus Supplement. In the event that any date
on which Distributions are payable on the Preferred Securities is not a Business
Day (as defined below), payment of the Distribution 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 to 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 either case with the same
force and effect as if made on such date (each date on which Distributions are
payable in accordance with the foregoing, a "Distribution Date"). A
 
                                       25
<PAGE>   56
 
"Business Day" shall mean any day other than a Saturday or a Sunday, or a day on
which banking institutions in The City of New York are authorized or required by
law or executive order to remain closed or a day on which the corporate trust
office of the Property Trustee or the Debenture Trustee is closed for business.
 
     Each Issuer's Preferred Securities represent beneficial ownership interests
in the applicable Issuer, and the Distributions on each Preferred Security will
be payable at a rate specified in the applicable Prospectus Supplement for such
Preferred Securities. The amount of Distributions payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months unless otherwise
specified in the applicable Prospectus Supplement. Distributions to which
holders of Preferred Securities are entitled will accumulate additional
Distributions at the rate per annum if and as specified in the applicable
Prospectus Supplement. The term "Distributions" as used herein includes any such
additional Distributions unless otherwise stated.
 
   
     If provided in the applicable Prospectus Supplement, the Corporation has
the right under the Indenture, pursuant to which it will issue the Corresponding
Junior Subordinated Debentures, to defer the payment of interest at any time or
from time to time on any series of the Corresponding Junior Subordinated
Debentures for up to such number of consecutive interest payment periods which
will be specified in such Prospectus Supplement relating to such series (each,
an "Extension Period"), provided that no Extension Period may extend beyond the
Stated Maturity of the Corresponding Junior Subordinated Debentures. As a
consequence of any such deferral, Distributions on the Related Preferred
Securities would be deferred (but would continue to accumulate additional
Distributions thereon at the rate per annum set forth in the Prospectus
Supplement for such Preferred Securities) by the Issuer of such Preferred
Securities during any such Extension Period. During such Extension Period, the
Corporation may not, and may not permit any subsidiary of the Corporation to,
(i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire or make a liquidation payment with respect to, any of the Corporation's
capital stock, (ii) make any payment of principal, interest or premium, if any,
on or repay, repurchase or redeem any debt securities of the Corporation that
rank pari passu with or junior in interest to the Corresponding Junior
Subordinated Debentures or (iii) make any guarantee payments with respect to any
guarantee by the Corporation of debt securities of any subsidiary of the
Corporation if such guarantee ranks pari passu with or junior in interest to the
Corresponding Junior Subordinated Debentures (other than (a) dividends or
distributions in capital stock of the Corporation, (b) any declaration of a
dividend in connection with the implementation of a stockholders' rights plan,
the redemption or repurchase of any such rights pursuant thereto, (c) payments
under the Guarantee with respect to such Preferred Securities and (d) purchases
of common stock related to the issuance of common stock or rights or options
under any of the Corporation's benefit plans for its directors, officers,
employees or other persons within the definition of "employee" for purposes of a
registration of shares for an employee benefit plan of the Corporation, related
to the issuance of common stock or rights under a dividend reinvestment and
stock purchase plan, or related to the issuance of common stock (or securities
convertible into or exchangeable for common stock) as consideration in an
acquisition transaction).
    
 
     The revenue of each Issuer available for distribution to holders of its
Preferred Securities will be limited to payments under the Corresponding Junior
Subordinated Debentures in which the Issuer will invest the proceeds from the
issuance and sale of its Trust Securities. See "Description of Junior
Subordinated Debentures -- Corresponding Junior Subordinated Debentures". If the
Corporation does not make interest payments on such Corresponding Junior
Subordinated Debentures, the Property Trustee will not have funds available to
pay Distributions on the Related Preferred Securities. The payment of
Distributions (if and to the extent the Issuer has funds legally available for
the payment of such Distributions and cash sufficient to make such payments) is
guaranteed by the Corporation on the basis set forth herein under "Description
of Guarantees".
 
     Distributions on the Preferred Securities will be payable to the holders
thereof as they appear on the register of such Issuer on the relevant record
dates, which, as long as the Preferred Securities remain in book-entry form,
will be one Business Day prior to the relevant Distribution
 
                                       26
<PAGE>   57
 
   
Date. Subject to any applicable laws and regulations and the provisions of the
applicable Trust Agreement, each such payment will be made as described under
"Book-Entry Issuance". In the event any Preferred Securities are not in
book-entry form, the relevant record date for such Preferred Securities shall be
15 days prior to the relevant Distribution Date, as specified in the applicable
Prospectus Supplement.
    
 
REDEMPTION OR EXCHANGE
 
     Mandatory Redemption.  Upon the repayment or redemption, in whole or in
part, of any Corresponding Junior Subordinated Debentures, whether at maturity
or upon earlier redemption as provided in the Indenture, the proceeds from such
repayment or redemption shall be applied by the Property Trustee to redeem a
Like Amount (as defined below) of the Trust Securities, upon not less than 30
nor more than 60 days notice, at a redemption price (the "Redemption Price")
equal to the aggregate Liquidation Amount of such Trust Securities plus
accumulated but unpaid Distributions thereon to the date of redemption (the
"Redemption Date") and the related amount of the premium, if any, paid by the
Corporation upon the concurrent redemption of such Corresponding Junior
Subordinated Debentures. See "Description of Junior Subordinated
Debentures -- Redemption". If less than all of any series of Corresponding
Junior Subordinated Debentures are to be repaid or redeemed on a Redemption
Date, then the proceeds from such repayment or redemption shall be allocated to
the redemption pro rata of the related Preferred Securities and the Common
Securities. The amount of premium, if any, paid by the Corporation upon the
redemption of all or any part of any series of any Corresponding Junior
Subordinated Debentures to be repaid or redeemed on a Redemption Date shall be
allocated to the redemption pro rata of the related Preferred Securities and the
Common Securities.
 
   
     The Corporation will have the right to redeem any series of Corresponding
Junior Subordinated Debentures (i) on or after such date as may be specified in
the applicable Prospectus Supplement, in whole at any time or in part from time
to time, or (ii) at any time, in whole (but not in part), upon the occurrence of
a Tax Event or Capital Treatment Event. The Corporation has committed to the
Reserve Bank that it will not cause any such redemption without having received
the prior approval of the Federal Reserve to do so, if then required under
applicable Federal Reserve capital guidelines or policies.
    
 
   
     Distribution of Corresponding Junior Subordinated Debentures.  The
Corporation has the right at any time to liquidate the related Issuer and, after
satisfaction of the liabilities of creditors of such Issuer as provided by
applicable law, cause such Corresponding Junior Subordinated Debentures in
respect of the Preferred Securities and Common Securities issued by such Issuer
to be distributed to the holders of such Preferred Securities and Common
Securities in exchange therefor upon liquidation of the Issuer. The Corporation
has committed to the Reserve Bank that it will not exercise its right to
liquidate an Issuer without having received the prior approval of the Federal
Reserve to do so, if then required under applicable Federal Reserve capital
guidelines or policies.
    
 
   
     Tax Event or Capital Treatment Event Redemption.  If a Tax Event or Capital
Treatment Event in respect of Junior Subordinated Debentures corresponding to a
series of Preferred Securities and Common Securities shall occur and be
continuing, the Corporation has the right to redeem the Corresponding Junior
Subordinated Debentures in whole (but not in part) and thereby cause a mandatory
redemption of such Preferred Securities and Common Securities in whole (but not
in part) at the Redemption Price within 90 days following the occurrence of such
Tax Event or Capital Treatment Event. In the event a Tax Event or Capital
Treatment Event in respect of Junior Subordinated Debentures corresponding to a
series of Preferred Securities and Common Securities has occurred and is
continuing and the Corporation does not elect to redeem the Corresponding Junior
Subordinated Debentures and thereby cause a mandatory redemption of such
Preferred Securities and Common Securities or to liquidate the related Issuer
and cause the Corresponding Junior Subordinated Debentures to be distributed to
holders of such Preferred Securities and Common Securities in exchange therefor
upon liquidation of the Issuer as described above, such
    
 
                                       27
<PAGE>   58
 
Preferred Securities will remain outstanding and Additional Sums (as defined
below) may be payable on the Corresponding Junior Subordinated Debentures.
 
   
     Possible Tax Law Changes.  On March 19, 1996, the Revenue Reconciliation
Bill of 1996 (the "Bill"), the revenue portion of President Clinton's budget
proposal, was released. The Bill would, among other things, generally deny
interest deductions for interest on an instrument issued by a corporation that
has a maximum weighted average maturity of more than 20 years and that is not
shown as indebtedness on the separate balance sheet of the issuer or, where the
instrument is issued to a related party (other than a corporation), where the
holder or some other related party issues a related instrument that is not shown
as indebtedness on the issuer's consolidated balance sheet. The above-described
provision of the Bill was proposed to be effective generally for instruments
issued on or after December 7, 1995. If this provision were to apply to the
Junior Subordinated Debentures, the Corporation would not be able to deduct
interest on the Junior Subordinated Debentures. However, on March 29, 1996, the
Chairmen of the Senate Finance and House Ways and Means Committees issued a
joint statement (the "Joint Statement") to the effect that it was their
intention that the effective date of the President's legislative proposals, if
adopted, would be no earlier than the date of appropriate Congressional action.
If the principles contained in the Joint Statement were followed and the Bill
was enacted, such legislation would not apply to the Junior Subordinated
Debentures. Although the 104th Congress adjourned without enacting the Bill,
there can be no assurance that future legislative proposals or final legislation
will not adversely affect the ability of the Corporation to deduct interest on
the Junior Subordinated Debentures or otherwise affect the tax treatment of the
transaction described herein. Moreover, such a change could give rise to a Tax
Event, which may permit the Corporation to cause a redemption of the Related
Preferred Securities. The Corporation has committed to the Reserve Bank that it
will not cause any such redemption without having received the prior approval of
the Federal Reserve to do so, if then required under applicable Federal Reserve
capital guidelines or policies.
    
 
     "Additional Sums" means the additional amounts as may be necessary in order
that the amount of Distributions then due and payable by an Issuer on the
outstanding Preferred Securities and Common Securities of the Issuer shall not
be reduced as a result of any additional taxes, duties and other governmental
charges to which such Issuer has become subject as a result of a Tax Event.
 
     "Like Amount" means (i) with respect to a redemption of any series of Trust
Securities, Trust Securities of such series having a Liquidation Amount (as
defined below) equal to that portion of the principal amount of Corresponding
Junior Subordinated Debentures to be contemporaneously redeemed in accordance
with the Indenture, allocated to the Common Securities and to the Preferred
Securities pro rata based upon the relative Liquidation Amounts of such classes
and the proceeds of which will be used to pay the Redemption Price of such Trust
Securities, and (ii) with respect to a distribution of Corresponding Junior
Subordinated Debentures to holders of any series of Trust Securities in exchange
therefor in connection with a dissolution or liquidation of the related Issuer,
Corresponding Junior Subordinated Debentures having a principal amount equal to
the Liquidation Amount of the Trust Securities of the holder to whom such
Corresponding Junior Subordinated Debentures would be distributed.
 
     "Liquidation Amount" means the stated amount of $25 per Trust Security.
 
   
     After the liquidation date fixed for any distribution of Corresponding
Junior Subordinated Debentures for any series of Preferred Securities (i) such
series of Preferred Securities will no longer be deemed to be outstanding, (ii)
the depository or its nominee, as the record holder of such series of Preferred
Securities, will receive a registered global certificate or certificates
representing the Corresponding Junior Subordinated Debentures to be delivered
upon such distribution and (iii) any certificates representing such series of
Preferred Securities not held by DTC or its nominee will be deemed to represent
the Corresponding Junior Subordinated Debentures having a principal amount equal
to the stated Liquidation Amount of such series of Preferred Securities, and
bearing accrued and unpaid interest in an amount equal to the accrued and unpaid
Distributions on such
    
 
                                       28
<PAGE>   59
 
series of Preferred Securities until such certificates are presented to the
Administrative Trustees or their agent for transfer or reissuance.
 
     There can be no assurance as to the market prices for the Preferred
Securities or the Corresponding Junior Subordinated Debentures that may be
distributed in exchange for Preferred Securities if a dissolution and
liquidation of an Issuer were to occur. Accordingly, the Preferred Securities
that an investor may purchase, or the Corresponding Junior Subordinated
Debentures that the investor may receive on dissolution and liquidation of an
Issuer, may trade at a discount to the price that the investor paid to purchase
the Preferred Securities offered hereby.
 
REDEMPTION PROCEDURES
 
     Preferred Securities redeemed on each Redemption Date shall be redeemed at
the Redemption Price with the applicable proceeds from the contemporaneous
redemption of the Corresponding Junior Subordinated Debentures. Redemptions of
the Preferred Securities shall be made and the Redemption Price shall be payable
on each Redemption Date only to the extent that the related Issuer has funds on
hand available for the payment of such Redemption Price. See also
"-- Subordination of Common Securities".
 
   
     If an Issuer gives a notice of redemption in respect of its Preferred
Securities, which are in book-entry form then, by 12:00 noon, New York City
time, on the Redemption Date, to the extent funds are available, the Property
Trustee will deposit irrevocably with DTC funds sufficient to pay the applicable
Redemption Price and will give DTC irrevocable instructions and authority to pay
the Redemption Price to the holders of such Preferred Securities. See
"Book-Entry Issuance". If such Preferred Securities are no longer in book-entry
form, the Property Trustee, to the extent funds are available, will irrevocably
deposit with the paying agent for such Preferred Securities funds sufficient to
pay the applicable Redemption Price and will give such paying agent irrevocable
instructions and authority to pay the Redemption Price to the holders thereof
upon surrender of their certificates evidencing such Preferred Securities.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Preferred Securities called for redemption shall be
payable to the holders of such Preferred 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 the holders of such Preferred Securities so called for redemption will
cease, except the right of the holders of such Preferred Securities to receive
the Redemption Price, but without interest on such Redemption Price, and such
Preferred Securities will cease to be outstanding. In the event that any date
fixed for redemption of Preferred Securities is not a Business Day, then payment
of the Redemption Price payable on such date will be made on the next succeeding
day which 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 the event that payment of the Redemption Price in respect of Preferred
Securities called for redemption is improperly withheld or refused and not paid
either by the Issuer or by the Corporation pursuant to the Guarantee as
described under "Description of Guarantees," Distributions on such Preferred
Securities will continue to accrue at the then applicable rate, from the
Redemption Date originally established by the Issuer for such Preferred
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.
    
 
     Subject to applicable law (including, without limitation, United States
federal securities law), the Corporation or its subsidiaries may at any time and
from time to time purchase outstanding Preferred Securities by tender, in the
open market or by private agreement.
 
     Payment of the Redemption Price on the Preferred Securities and any
distribution of Corresponding Junior Subordinated Debentures to holders of
Preferred Securities shall be made to the applicable recordholders thereof as
they appear on the register for such Preferred Securities on the relevant record
date, which shall be one Business Day prior to the relevant Redemption Date or
 
                                       29
<PAGE>   60
 
   
liquidation date, as applicable; provided, however, that in the event that any
Preferred Securities are not in book-entry form, the relevant record date for
such Preferred Securities shall be 15 days prior to the Redemption Date or
liquidation date, as applicable, or as otherwise specified in the applicable
Prospectus Supplement.
    
 
     If less than all of the Preferred Securities and Common Securities issued
by an Issuer are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of such Preferred Securities and Common Securities to be
redeemed shall be allocated pro rata to the Preferred Securities and the Common
Securities based upon the relative Liquidation Amounts of such classes. The
particular Preferred Securities to be redeemed shall be selected on a pro rata
basis 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 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 trust 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 each 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 aggregate Liquidation Amount of Preferred Securities which
has been or is to be redeemed.
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the Redemption Date to each holder of Trust Securities to be
redeemed at its registered address.
 
SUBORDINATION OF COMMON SECURITIES
 
     Payment of Distributions on, and the Redemption Price of, each Issuer's
Preferred Securities and Common Securities, as applicable, shall be made pro
rata based on the Liquidation Amount of such Preferred Securities and Common
Securities; provided, however, that if on any Distribution Date or Redemption
Date a Debenture Event of Default shall have occurred and be continuing, no
payment of any Distribution on, or Redemption Price of, any of the Issuer's
Common Securities, and no other payment on account of the redemption,
liquidation or other acquisition of such Common Securities, shall be made unless
payment in full in cash of all accumulated and unpaid Distributions on all of
the Issuer's 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 of the Issuer's
outstanding Preferred Securities then called for redemption, shall have been
made or provided for, and all funds available to the Property Trustee shall
first be applied to the payment in full in cash of all Distributions on, or
Redemption Price of, the Issuer's Preferred Securities then due and payable.
 
     In the case of any event of default under the applicable Trust Agreement
resulting from a Debenture Event of Default, the Corporation as holder of such
Issuer's Common Securities will be deemed to have waived any right to act with
respect to any such event of default under the applicable Trust Agreement until
the effect of all such events of default with respect to such Preferred
Securities have been cured, waived or otherwise eliminated. Until all events of
default under the applicable Trust Agreement with respect to the Preferred
Securities have been so cured, waived or otherwise eliminated, the Property
Trustee shall act solely on behalf of the holders of such Preferred Securities
and not on behalf of the Corporation as holder of the Issuer's Common
Securities, and only the holders of such Preferred Securities will have the
right to direct the Property Trustee to act on their behalf.
 
                                       30
<PAGE>   61
 
LIQUIDATION DISTRIBUTION UPON TERMINATION
 
   
     Pursuant to each Trust Agreement, each Issuer shall automatically terminate
upon expiration of its term and shall terminate on the first to occur of: (i)
certain events of bankruptcy, dissolution or liquidation of the Holder of the
Common Securities; (ii) the distribution of a Like Amount of the Corresponding
Junior Subordinated Debentures to the holders of its Trust Securities, if the
Corporation, as Depositor, has given written direction to the Property Trustee
to terminate such Issuer (subject to the Corporation having received prior
approval of the Federal Reserve if so required under applicable capital
guidelines or policies); (iii) redemption of all of the Issuer's Preferred
Securities as described under " -- Redemption or Exchange -- Mandatory
Redemption"; and (iv) the entry of an order for the dissolution of the Issuer by
a court of competent jurisdiction.
    
 
     If an early termination occurs as described in clause (i), (ii) or (iv)
above, the Issuer shall be liquidated by the Issuer Trustees as expeditiously as
the Issuer Trustees determine to be possible by distributing, after satisfaction
of liabilities to creditors of such Issuer as provided by applicable law, to the
holders of such Trust Securities in exchange therefor a Like Amount of the
Corresponding Junior Subordinated Debentures, unless such distribution is
determined by the Property Trustee not to be practical, in which event such
holders will be entitled to receive out of the assets of the Issuer available
for distribution to holders, after satisfaction of liabilities to creditors of
such Issuer as provided by applicable law, an amount equal to, in the case of
holders of Preferred Securities, the aggregate of the Liquidation Amount plus
accrued and unpaid Distributions thereon to the date of payment (such amount
being the "Liquidation Distribution"). If such Liquidation Distribution can be
paid only in part because such Issuer has insufficient assets available to pay
in full the aggregate Liquidation Distribution, then the amounts payable
directly by such Issuer on its Preferred Securities shall be paid on a pro rata
basis. The holder(s) of such Issuer's Common Securities will be entitled to
receive distributions upon any such liquidation pro rata with the holders of its
Preferred Securities, except that if a Debenture Event of Default has occurred
and is continuing, the Preferred Securities shall have a priority over the
Common Securities.
 
EVENTS OF DEFAULT; NOTICE
 
     Any one of the following events constitutes an "Event of Default" under
each Trust Agreement with respect to the Preferred Securities issued thereunder
(whatever the reason for such Event of Default and whether it shall be voluntary
or involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):
 
          (i) the occurrence of a Debenture Event of Default under the Indenture
     (see "Description of Junior Subordinated Debentures -- Debenture Events of
     Default"); or
 
          (ii) default by the Property Trustee in the payment of any
     Distribution when it becomes due and payable, and continuation of such
     default for a period of 30 days; or
 
          (iii) default by the Property Trustee in the payment of any Redemption
     Price of any Trust Security when it becomes due and payable; or
 
          (iv) default in the performance, or breach, in any material respect,
     of any covenant or warranty of the Issuer Trustees in such Trust Agreement
     (other than a covenant or warranty a default in the performance of which or
     the breach of which is dealt with in clause (ii) or (iii) above), and
     continuation of such default or breach for a period of 90 days after there
     has been given, by registered or certified mail, to the defaulting Issuer
     Trustee or Trustees by the holders of at least 25% in aggregate Liquidation
     Amount of the outstanding Preferred Securities of the applicable Issuer, a
     written notice specifying such default or breach and requiring it to be
     remedied and stating that such notice is a "Notice of Default" under such
     Trust Agreement; or
 
                                       31
<PAGE>   62
 
          (v) the occurrence of certain events of bankruptcy or insolvency with
     respect to the Property Trustee and the failure by the Corporation to
     appoint a successor Property Trustee within 90 days thereof.
 
     Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit
notice of such Event of Default to the holders of such Issuer's Preferred
Securities, the Administrative Trustees and the Corporation, as Depositor,
unless such Event of Default shall have been cured or waived. The Corporation,
as Depositor, and the Administrative Trustees are required to file annually with
the Property Trustee a certificate as to whether or not they are in compliance
with all the conditions and covenants applicable to them under each Trust
Agreement.
 
     If a Debenture Event of Default has occurred and is continuing, the
Preferred Securities shall have a preference over the Common Securities as
described above. See "Subordination of Common Securities" and "-- Liquidation
Distribution Upon Termination". The existence of an Event of Default does not
entitle the holders of Preferred Securities to accelerate the maturity thereof.
 
REMOVAL OF ISSUER TRUSTEES
 
     Unless a Debenture Event of Default shall have occurred and be continuing,
any Issuer Trustee may be removed at any time by the holder of the Common
Securities. If a Debenture Event of Default has occurred and is continuing, the
Property Trustee and the Delaware Trustee may be removed at such time by the
holders of a majority in Liquidation Amount of the outstanding Preferred
Securities. In no event will the holders of the Preferred Securities have the
right to vote to appoint, remove or replace the Administrative Trustees, which
voting rights are vested exclusively in the Corporation as the holder of the
Common Securities. No resignation or removal of an Issuer Trustee and no
appointment of a successor trustee shall be effective until the acceptance of
appointment by the successor trustee in accordance with the provisions of the
applicable Trust Agreement.
 
CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE
 
   
     Unless an Event of Default shall have occurred and be continuing, at any
time or from time to time, 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 Corporation, as the holder of the
Common Securities, and the Administrative Trustees shall have power to appoint
one or more persons either to act as a co-trustee, jointly with the Property
Trustee, of all or any part of such Trust Property, or 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 such
capacity any property, title, right or power deemed necessary or desirable,
subject to the provisions of the applicable Trust Agreement. In case a Event of
Default has occurred and is continuing, the Property Trustee alone shall have
power to make such appointment.
    
 
MERGER OR CONSOLIDATION OF ISSUER TRUSTEES
 
     Any Person into which the Property Trustee, the Delaware Trustee or any
Administrative Trustee that is not a natural person may be merged or converted
or with which it may be consolidated, or any Person resulting from any merger,
conversion or consolidation to which such Trustee shall be a party, or any
Person succeeding to all or substantially all the corporate trust business of
such Trustee, shall be the successor of such Trustee under each Trust Agreement,
provided such Person shall be otherwise qualified and eligible.
 
MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE ISSUERS
 
     An Issuer may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except as
described below. An Issuer may, at the request of the Corporation, with the
 
                                       32
<PAGE>   63
 
   
consent of the Administrative Trustees and without the consent of the holders of
the Preferred Securities, 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 such Issuer with respect to the Preferred Securities or
(b) substitutes for the Preferred Securities other securities having
substantially the same terms as the Preferred Securities (the "Successor
Securities") so long as the Successor Securities rank the same as the Preferred
Securities in priority with respect to distributions and payments upon
liquidation, redemption and otherwise, (ii) the Corporation expressly appoints a
trustee of such successor entity possessing the same powers and duties as the
Property Trustee as the holder of the Corresponding Junior Subordinated
Debentures, (iii) the Successor Securities are listed, 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, if any, (iv) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not cause the Preferred Securities to be
downgraded by any nationally recognized statistical rating organization which
gives ratings on the Preferred Securities, (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 Issuer, (vii) prior
to such merger, consolidation, amalgamation, replacement, conveyance, transfer
or lease, the Corporation has received an opinion from independent counsel to
the Issuer experienced in such matters 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 Issuer nor such
successor entity will be required to register as an investment company under the
Investment Company Act of 1940, as amended (the "Investment Company Act"), and
(viii) the Corporation or any permitted successor or assignee 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, an Issuer 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
Issuer or the successor entity to be taxable as a corporation or classified as
other than a grantor trust for United States federal income tax purposes.
    
 
VOTING RIGHTS; AMENDMENT OF EACH TRUST AGREEMENT
 
     Except as provided below and under "Description of Guarantees -- Amendments
and Assignment" and as otherwise required by law and the applicable Trust
Agreement, the holders of the Preferred Securities will have no voting rights.
 
   
     Each Trust Agreement may be amended from time to time by the Corporation,
the Property Trustee and the Administrative Trustees, without the consent of the
holders of the Preferred Securities (i) to cure any ambiguity, correct or
supplement any provisions in such Trust Agreement that may be inconsistent with
any other provision, or to make any other provisions with respect to matters or
questions arising under such Trust Agreement, which shall not be inconsistent
with the other provisions of such Trust Agreement, or (ii) to modify, eliminate
or add to any provisions of such Trust Agreement to such extent as shall be
necessary to ensure that the Issuer will not be taxable as a corporation and
will be classified as a grantor trust for United States federal income tax
purposes at all times that any Trust Securities are outstanding or to ensure
that the Issuer will not be required to register as an "investment company"
under the Investment Company Act; provided,
    
 
                                       33
<PAGE>   64
 
   
however, that in the case of either clause (i) or clause (ii), such action shall
not adversely affect in any material respect the interests of any holder of
Preferred Securities, and any amendments of such Trust Agreement shall become
effective when notice thereof is given to the holders of Trust Securities. Each
Trust Agreement may be amended by the Issuer Trustees and the Corporation with
(i) the consent of holders representing not less than a majority (based upon
Liquidation Amounts) of the outstanding Trust Securities, and (ii) receipt by
the Issuer Trustees of an opinion of counsel to the effect that such amendment
or the exercise of any power granted to the Issuer Trustees in accordance with
such amendment will not affect the Issuer's status as a grantor trust for United
States federal income tax purposes, or the Issuer's exemption from status as an
"investment company" under the Investment Company Act or cause the Issuer to be
taxable as a corporation for United States federal income tax purposes, provided
that without the consent of each holder of Trust Securities, such Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a holder of Trust Securities to
institute suit for the enforcement of any such payment on or after such date.
    
 
   
     So long as any Corresponding Junior Subordinated Debentures are held by the
Property Trustee, the Issuer Trustees shall not (i) direct the time, method and
place of conducting any proceeding for any remedy available to the Debenture
Trustee, or executing any trust or power conferred on the Property Trustee with
respect to such Corresponding Junior Subordinated Debentures, (ii) waive any
past default that is waivable under the Indenture, (iii) exercise any right to
rescind or annul a declaration that the principal of all the Junior Subordinated
Debentures shall be due and payable or (iv) consent to any amendment,
modification or termination of the Indenture or such Corresponding Junior
Subordinated Debentures, where such consent shall be required, without, in each
case, obtaining the prior approval of the holders of a majority in aggregate
Liquidation Amount of all outstanding Preferred Securities; provided, however,
that where a consent under the Indenture would require the consent of each
holder of Corresponding Junior Subordinated Debentures affected thereby, no such
consent shall be given by the Property Trustee without the prior consent of each
holder of the corresponding Preferred Securities. The Issuer Trustees shall not
revoke any action previously authorized or approved by a vote of the holders of
the Preferred Securities except by subsequent vote of the holders of the
Preferred Securities. The Property Trustee shall notify each holder of Preferred
Securities of any notice of default with respect to the Corresponding Junior
Subordinated Debentures. In addition to obtaining the foregoing approvals of the
holders of the Preferred Securities, prior to taking any of the foregoing
actions, the Issuer Trustees shall obtain an opinion of counsel experienced in
such matters to the effect that such action would not cause the Issuer to be
classified as other than a grantor trust or to be taxable as a corporation for
United States federal income tax purposes.
    
 
     Any required approval of holders of Preferred Securities may be given at a
meeting of holders of Preferred Securities convened for such purpose or pursuant
to written consent. The Property Trustee will cause a notice of any meeting at
which holders of Preferred Securities are entitled to vote, or of any matter
upon which action by written consent of such holders is to be taken, to be given
to each holder of record of Preferred Securities in the manner set forth in each
Trust Agreement.
 
     No vote or consent of the holders of Preferred Securities will be required
for an Issuer to redeem and cancel its Preferred Securities in accordance with
the applicable Trust Agreement.
 
     Notwithstanding that holders of Preferred Securities are entitled to vote
or consent under any of the circumstances described above, any of the Preferred
Securities that are owned by the Corporation, the Issuer Trustees or any
affiliate of the Corporation or any Issuer Trustees, shall, for purposes of such
vote or consent, be treated as if they were not outstanding.

GLOBAL PREFERRED SECURITIES
 
     The Preferred Securities of a series may be issued in whole or in part in
the form of one or more Global Preferred Securities that will be deposited with,
or on behalf of, the Depositary identified in the Prospectus Supplement relating
to such series. Unless otherwise indicated in the applicable Prospectus
Supplement for such series, the Depositary will be DTC. Global Preferred
Securities may be issued only in fully registered form and in either temporary
or permanent form. Unless and until it is exchanged in whole or in part for the
individual Preferred Securities represented thereby, a Global Preferred Security
may not be transferred except as a whole by the Depositary for such Global
Preferred Security to a nominee of such Depositary or by a nominee of such
Depositary to such Depositary or another nominee of such Depositary or by the
Depositary or any nominee to a successor Depositary or any nominee of such
successor.
 
     The specific terms of the depositary arrangement with respect to a series
of Preferred Securities will be described in the Prospectus Supplement relating
to such series. The Corporation anticipates that the following provisions will
generally apply to depositary arrangements.
 
     Upon the issuance of a Global Preferred Security, and the deposit of such
Global Preferred Security with or on behalf of the Depositary, the Depositary
for such Global Preferred Security or its nominee will credit, on its book-entry
registration and transfer system, the respective aggregate Liquidation Amounts
of the individual Preferred Securities represented by such Global Preferred
Securities to the accounts of Participants. Such accounts shall be designated by
the dealers, underwriters or agents with respect to such Preferred Securities or
by the Corporation if such Preferred Securities are offered and sold directly by
the Corporation. Ownership of beneficial interests in a Global Preferred
Security will be limited to Participants or persons that may hold interests
through Participants. Ownership of beneficial interests in such Global Preferred
Security will be shown on, and the transfer of that ownership will be effected
only through, records maintained by the applicable Depositary or its nominee
(with respect to interests of Participants) and the records of Participants
(with respect to interests of persons who hold through Participants). The laws
of some states require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability to transfer beneficial interests in a Global Preferred
Security.
 
     So long as the Depositary for a Global Preferred Security, or its nominee,
is the registered owner of such Global Preferred Security, such Depositary or
such nominee, as the case may be, will be considered the sole owner or holder of
the Preferred Securities represented by such Global Preferred Security for all
purposes under the Indenture governing such Preferred Securities. Except as
provided below, owners of beneficial interests in a Global Preferred Security
will not be entitled to have any of the individual Preferred Securities of the
series represented by such Global Preferred Security registered in their names,
will not receive or be entitled to receive physical delivery of any such
Preferred Securities of such series in definitive form and will not be
considered the owners or holders thereof under the Indenture.
 
     Payments of principal of (and premium, if any) and interest on individual
Preferred Securities represented by a Global Preferred Security registered in
the name of a Depositary or its nominee will be made to the Depositary or its
nominee, as the case may be, as the registered owner of the Global Preferred
Security representing such Preferred Securities. None of the Corporation, the
Property Trustee, any Paying Agent, or the Securities Registrar for such
Preferred Securities will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests of the Global Preferred Security representing such Preferred
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
 
     The Corporation expects that the Depositary for a series of Preferred
Securities or its nominee, upon receipt of any payment of Liquidation Amount,
Redemption Price, premium or Distributions in respect of a permanent Global
Preferred Security representing any of such Preferred Securities,
 
                                       35
<PAGE>   66
 
immediately will credit Participants' accounts with payments in amounts
proportionate to their respective beneficial interest in the aggregate
Liquidation Amount of such Global Preferred Security for such Preferred
Securities as shown on the records of such Depositary or its nominee. The
Corporation also expects that payments by Participants to owners of beneficial
interests in such Global Preferred Security held through such Participants will
be governed by standing instructions and customary practices, as is now the case
with securities held for the accounts of customers in bearer form or registered
in "street name." Such payments will be the responsibility of such Participants.
 
     Unless otherwise specified in the applicable Prospectus Supplement, if a
Depositary for a series of Preferred Securities is at any time unwilling, unable
or ineligible to continue as depositary and a successor depositary is not
appointed by the Issuer within 90 days, the Issuer will issue individual
Preferred Securities of such series in exchange for the Global Preferred
Security representing such series of Preferred Securities. In addition, the
Issuer may at any time and in its sole discretion, subject to any limitations
described in the Prospectus Supplement relating to such Preferred Securities,
determine not to have any Preferred Securities of such series represented by one
or more Global Preferred Securities and, in such event, will issue individual
Preferred Securities of such series in exchange for the Global Preferred
Security or Securities representing such series of Preferred Securities.
Further, if the Issuer so specifies with respect to the Preferred Securities of
a series, an owner of a beneficial interest in a Global Preferred Security
representing Preferred Securities of such series may, on terms acceptable to the
Issuer, the Property Trustee and the Depositary for such Global Preferred
Security, receive individual Preferred Securities of such series in exchange for
such beneficial interests, subject to any limitations described in the
Prospectus Supplement relating to such Preferred Securities. In any such
instance, an owner of a beneficial interest in a Global Preferred Security will
be entitled to physical delivery of individual Preferred Securities of the
series represented by such Global Preferred Security equal in principal amount
to such beneficial interest and to have such Preferred Securities registered in
its name. Individual Preferred Securities of such series so issued will be
issued in denominations, unless otherwise specified by the Issuer, of $25 and
integral multiples thereof.
 
TRUST EXPENSES
 
   
     Pursuant to each Trust Agreement, the Holder of the Common Securities will
be liable to the Issuer for all the debts, expenses and obligations of such
Issuer (other than obligations of the Issuer to pay to the holders of any
Preferred Securities or other similar interests in the Issuer the amounts due
such holders pursuant to the terms of the Preferred Securities or such other
similar interests, as the case may be) to the extent not satisfied out of the
Issuer's assets.
    
 
PAYMENT AND PAYING AGENCY
 
     Payments in respect of the Preferred Securities shall be made to the
Depositary, which shall credit the relevant accounts at the Depositary on the
applicable Distribution Dates or, if any Issuer's Preferred Securities are not
held by the Depositary, such payments shall be made by wire transfer, direct
deposit or check mailed to the address of the holder entitled thereto as such
address shall appear on the Register. Unless otherwise specified in the
applicable Prospectus Supplement, the paying agent (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 Corporation. The
Paying Agent shall be permitted to resign as Paying Agent upon 30 days' written
notice to the Property Trustee and the Corporation. In the event that the
Property Trustee shall no longer be the Paying Agent, the Administrative
Trustees shall appoint a successor (which shall be a bank or trust company
acceptable to the Administrative Trustees and the Corporation) to act as Paying
Agent.
 
REGISTRAR AND TRANSFER AGENT
 
     Unless otherwise specified in the applicable Prospectus Supplement, the
Property Trustee will act as registrar and transfer agent for the Preferred
Securities.

     Registration of transfers of Preferred Securities will be effected without
charge by or on behalf of each Issuer, but upon payment of any tax or other
governmental charges that may be imposed in connection with any transfer or
exchange. The Issuers will not be required to register or cause to be registered
the transfer of their Preferred Securities after such Preferred Securities have
been called for redemption.
 
INFORMATION CONCERNING THE PROPERTY TRUSTEE
 
   
     The Property Trustee, other than during the occurrence and continuance of
an Event of Default, will perform only such duties as are specifically set forth
in each Trust Agreement and in the Trust Indenture Act and, after such Event of
Default, must exercise the same degree of care and skill as a prudent person
would exercise or use in the conduct of his or her own affairs. Subject to this
provision, the Property Trustee is under no obligation to exercise any of the
powers vested in it by the applicable Trust Agreement at the request of any
holder of Preferred Securities unless it is offered reasonable indemnity against
the costs, expenses and liabilities that might be incurred thereby. If no Event
of Default has occurred and is continuing and the Property Trustee is required
to decide between alternative causes of action, construe ambiguous provisions in
the applicable Trust Agreement or is unsure of the application of any provision
of the applicable Trust Agreement, and the matter is not one on which holders of
Preferred Securities are entitled under such Trust Agreement to vote, then the
Property Trustee shall take such action as is directed by the Corporation and if
not so directed, shall take such action as it deems advisable and in the best
interests of the holders of the Trust Securities and will have no liability
except for its own bad faith, negligence or willful misconduct.
    
 
MISCELLANEOUS
 
   
     The Administrative Trustees are authorized and directed to conduct the
affairs of and to operate the Issuers in such a way that no Issuer will be
deemed to be an "investment company" required to be registered under the
Investment Company Act or taxable as a corporation or classified as other than a
grantor trust for United States federal income tax purposes and so that the
Corresponding Junior Subordinated Debentures will be treated as indebtedness of
the Corporation for United States federal income tax purposes. In this
connection, the Corporation and the Administrative Trustees are authorized to
take any action, not inconsistent with applicable law, the certificate of trust
of each Issuer or each Trust Agreement, that the Corporation and the
Administrative Trustees determine in their discretion to be necessary or
desirable for such purposes, as long as such action does not materially
adversely affect the interests of the holders of the related Preferred
Securities.
    
 
     Holders of the Preferred Securities have no preemptive or similar rights.
 
     No Issuer may borrow money or issue debt or mortgage or pledge any of its
assets.
 
                              BOOK-ENTRY ISSUANCE
 
   
     DTC will act as securities depositary for all of the Preferred Securities
and the Junior Subordinated Debentures, unless otherwise referred to in the
Prospectus Supplement relating to an offering of Preferred Securities or Junior
Subordinated Debentures. Unless otherwise specified in the applicable Prospectus
Supplement, the Preferred Securities and the Junior Subordinated Debentures will
be issued only as fully-registered securities registered in the name of Cede &
Co. (DTC's nominee). One or more fully-registered global certificates will be
issued for the Preferred Securities of each Issuer and the Junior Subordinated
Debentures, representing in the aggregate the total number of such Issuer's
Preferred Securities or aggregate principal balance of Junior Subordinated
Debentures, respectively, and will be deposited with DTC.
    
 
     DTC is a limited purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. DTC
holds securities that its Participants deposit with DTC. DTC also facilitates
the
 
                                       37
<PAGE>   68
 
settlement among Participants of securities transactions, such as transfers and
pledges, in deposited securities through electronic computerized book-entry
changes in Participants' accounts, thereby eliminating the need for physical
movement of securities certificates. "Direct Participants" include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations. DTC is owned by a number of its Direct Participants and by
the New York Stock Exchange, Inc., the American Stock Exchange, Inc. and the
National Association of Securities Dealers, Inc. Access to the DTC system is
also available to others such as securities brokers and dealers, banks and trust
companies that clear through or maintain custodial relationships with Direct
Participants, either directly or indirectly ("Indirect Participants"). The rules
applicable to DTC and its Participants are on file with the Commission.
 
     Purchases of Preferred Securities or Junior Subordinated Debentures within
the DTC system must be made by or through Direct Participants, which will
receive a credit for the Preferred Securities or Junior Subordinated Debentures
on DTC's records. The ownership interest of each actual purchaser of each
Preferred Security and each Junior Subordinated Debenture ("Beneficial Owner")
is in turn to be recorded on the Direct and Indirect Participants' records.
Beneficial Owners will not receive written confirmation from DTC of their
purchases, but Beneficial Owners are expected to receive written confirmations
providing details of the transactions, as well as periodic statements of their
holdings, from the Direct or Indirect Participants through which the Beneficial
Owners purchased Preferred Securities or Junior Subordinated Debentures.
Transfers of ownership interests in the Preferred Securities or Junior
Subordinated Debentures are to be accomplished by entries made on the books of
Participants acting on behalf of Beneficial Owners. Beneficial Owners will not
receive certificates representing their ownership interests in Preferred
Securities or Junior Subordinated Debentures, except in the event that use of
the book-entry system for the Preferred Securities of such Issuer or Junior
Subordinated Debentures is discontinued.
 
     DTC has no knowledge of the actual Beneficial Owners of the Preferred
Securities or Junior Subordinated Debentures; DTC's records reflect only the
identity of the Direct Participants to whose accounts such Preferred Securities
or Junior Subordinated Debentures are credited, which may or may not be the
Beneficial Owners. The Participants will remain responsible for keeping account
of their holdings on behalf of their customers.
 
     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners and the voting
rights of Direct Participants, Indirect Participants and Beneficial Owners will
be governed by arrangements among them, subject to any statutory or regulatory
requirements as may be in effect from time to time.
 
     Redemption notices will be sent to Cede & Co. as the registered holder of
the Preferred Securities or Junior Subordinated Debentures. If less than all of
an Issuer's Preferred Securities or the Junior Subordinated Debentures are being
redeemed, DTC's current practice is to determine by lot the amount of the
interest of each Direct Participant to be redeemed.
 
     Although voting with respect to the Preferred Securities or the Junior
Subordinated Debentures is limited to the holders of record of the Preferred
Securities or Junior Subordinated Debentures, in those instances in which a vote
is required, neither DTC nor Cede & Co. will itself consent or vote with respect
to Preferred Securities or Junior Subordinated Debentures. Under its usual
procedures, DTC would mail an omnibus proxy (the "Omnibus Proxy") to the
relevant Trustee as soon as possible after the record date. The Omnibus Proxy
assigns Cede & Co.'s consenting or voting rights to those Direct Participants to
whose accounts such Preferred Securities or Junior Subordinated Debentures are
credited on the record date (identified in a listing attached to the Omnibus
Proxy).
 
     Distribution payments on the Preferred Securities or the Junior
Subordinated Debentures will be made by the relevant Trustee to DTC. DTC's
practice is to credit Direct Participants' accounts on the relevant payment date
in accordance with their respective holdings shown on DTC's records unless DTC
has reason to believe that it will not receive payments on such payment date.
Payments by
 
                                       38
<PAGE>   69
 
Participants to Beneficial Owners will be governed by standing instructions and
customary practices and will be the responsibility of such Participant and not
of DTC, the relevant Trustee, the Issuer thereof or the Corporation, subject to
any statutory or regulatory requirements as may be in effect from time to time.
Payment of Distributions to DTC is the responsibility of the relevant Trustee,
disbursement of such payments to Direct Participants is the responsibility of
DTC, and disbursements of such payments to the Beneficial Owners is the
responsibility of Direct and Indirect Participants.
 
     DTC may discontinue providing its services as securities depositary with
respect to any of the Preferred Securities or the Junior Subordinated Debentures
at any time by giving reasonable notice to the relevant Trustee and the
Corporation. In the event that a successor securities depositary is not
obtained, definitive Preferred Security or Junior Subordinated Debenture
certificates representing such Preferred Securities or Junior Subordinated
Debentures are required to be printed and delivered. The Corporation, at its
option, may decide to discontinue use of the system of book-entry transfers
through DTC (or a successor depositary). After a Debenture Event of Default, the
holders of a majority in liquidation preference of Preferred Securities or
aggregate principal amount of Junior Subordinated Debentures may determine to
discontinue the system of book-entry transfers through DTC. In any such event,
definitive certificates for such Preferred Securities or Junior Subordinated
Debentures will be printed and delivered.
 
     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Issuers and the Corporation believe to
be accurate, but the Issuers and the Corporation assume no responsibility for
the accuracy thereof. Neither the Issuers nor the Corporation has any
responsibility for the performance by DTC or its Participants of their
respective obligations as described herein or under the rules and procedures
governing their respective operations.
 
                           DESCRIPTION OF GUARANTEES
 
   
     A Guarantee will be executed and delivered by the Corporation concurrently
with the issuance by each Issuer of its Preferred Securities for the benefit of
the holders from time to time of such Preferred Securities. The Bank of New York
will act as indenture trustee ("Guarantee Trustee") under each Guarantee for the
purposes of compliance with the Trust Indenture Act and each Guarantee will be
qualified as an indenture under the Trust Indenture Act. This summary of certain
provisions of the Guarantees, which summarizes material terms thereof, does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, all of the provisions of each Guarantee, including the definitions
therein of certain terms, and the Trust Indenture Act, to each of which
reference is hereby made. The form of the Guarantee has been filed as an exhibit
to the Registration Statement of which this Prospectus forms a part. Reference
in this summary to Preferred Securities means that Issuer's Preferred Securities
to which a Guarantee relates. The Guarantee Trustee will hold each Guarantee for
the benefit of the holders of the related Issuer's Preferred Securities.
    
 
GENERAL
 
     The Corporation will irrevocably agree to pay in full on a subordinated
basis, to the extent set forth herein, the Guarantee Payments (as defined below)
to the holders of the Preferred Securities, as and when due, regardless of any
defense, right of set-off or counterclaim that such Issuer may have or assert
other than the defense of payment. The following payments with respect to the
Preferred Securities, to the extent not paid by or on behalf of the related
Issuer (the "Guarantee Payments"), will be subject to the Guarantee: (i) any
accumulated and unpaid Distributions required to be paid on such Preferred
Securities, to the extent that such Issuer has funds on hand available therefor
at such time, (ii) the Redemption Price with respect to any Preferred Securities
called for redemption, to the extent that such Issuer has funds on hand
available therefor at such
 
                                       39
<PAGE>   70
 
   
time, or (iii) upon a voluntary or involuntary dissolution, winding up or
liquidation of such Issuer (unless the Corresponding Junior Subordinated
Debentures are distributed to holders of such Preferred Securities in exchange
therefor), the lesser of (a) the Liquidation Distribution to the extent that
such Issuer has funds on hand availabe therefor at such time and (b) the amount
of assets of such Issuer remaining available for distribution to holders of
Preferred Securities after satisfaction of liabilities to creditors of such
Issuer as required by applicable law. The Corporation's obligation to make a
Guarantee Payment may be satisfied by direct payment of the required amounts by
the Corporation to the holders of the applicable Preferred Securities or by
causing the Issuer to pay such amounts to such holders.
    
 
     Each Guarantee will be an irrevocable guarantee on a subordinated basis of
the related Issuer's obligations under the Preferred Securities, but will apply
only to the extent that such related Issuer has funds sufficient to make such
payments, and is not a guarantee of collection.
 
   
     If the Corporation does not make interest payments on the Corresponding
Junior Subordinated Debentures held by the Issuer, the Issuer will not be able
to pay Distributions on the Preferred Securities and will not have funds legally
available therefor. Each Guarantee will rank subordinate and junior in right of
payment to all Senior Indebtedness of the Corporation. See "-- Status of the
Guarantees". Because the Corporation is a holding company, the right of the
Corporation to participate in any distribution of assets of any subsidiary upon
such subsidiary's liquidation or reorganization or otherwise, is subject to the
prior claims of creditors of that subsidiary, except to the extent the
Corporation may itself be recognized as a creditor of that subsidiary.
Accordingly, the Corporation's obligations under the Guarantees will be
effectively subordinated to all existing and future liabilities of the
Corporation's subsidiaries, and claimants should look only to the assets of the
Corporation for payments thereunder. Except as otherwise provided in the
applicable Prospectus Supplement, the Guarantees do not limit the incurrence or
issuance of other secured or unsecured debt of the Corporation, including Senior
Debt, whether under the Indenture, any other existing indenture or any other
indenture that the Corporation may enter into in the future or otherwise. See
the applicable Prospectus Supplement relating to any offering of Preferred
Securities.
    
 
     The Corporation has, through the applicable Guarantee, the applicable Trust
Agreement, the applicable series of Corresponding Junior Subordinated Debentures
and the Indenture, taken together, fully, irrevocably and unconditionally
guaranteed all of the Issuer's obligations under the Preferred Securities. No
single document standing alone or operating in conjunction with fewer than all
of the other documents constitutes such guarantee. It is only the combined
operation of these documents that has the effect of providing a full,
irrevocable and unconditional guarantee of the Issuer's obligations under the
Preferred Securities. See "Relationship Among the Preferred Securities, the
Corresponding Junior Subordinated Debentures and the Guarantees".
 
STATUS OF THE GUARANTEES
 
   
     Each Guarantee will constitute an unsecured obligation of the Corporation
and will rank subordinate and junior in right of payment to all Senior
Indebtedness of the Corporation in the same manner as the Junior Subordinated
Debentures.
    
 
   
     Each Guarantee will rank pari passu with all other Guarantees issued by the
Corporation. Each Guarantee will constitute a guarantee of payment and not of
collection (i.e., the guaranteed party may institute a legal proceeding directly
against the Guarantor to enforce its rights under the Guarantee without first
instituting a legal proceeding against any other person or entity). Each
Guarantee will be held for the benefit of the holders of the related Preferred
Securities. Each Guarantee will not be discharged except by payment of the
Guarantee Payments in full to the extent not paid by the Issuer or upon
distribution to the holders of the Preferred Securities of the Corresponding
Junior Subordinated Debentures. None of the Guarantees places a limitation on
the amount of additional Senior Indebtedness that may be incurred by the
Corporation. The Corporation expects from time to time to incur additional
indebtedness constituting Senior Indebtedness.
    
 
                                       40
<PAGE>   71
 
AMENDMENTS AND ASSIGNMENT
 
   
     Except with respect to any changes which do not materially adversely affect
the rights of holders of the related Preferred Securities (in which case no vote
will be required), no Guarantee may be amended without the prior approval of the
holders of not less than a majority of the aggregate Liquidation Amount of the
related outstanding Preferred Securities. The manner of obtaining any such
approval will be as set forth under "Description of Preferred
Securities -- Voting Rights; Amendment of Each Trust Agreement". All guarantees
and agreements contained in each Guarantee shall bind the successors, assigns,
receivers, trustees and representatives of the Corporation and shall inure to
the benefit of the holders of the related Preferred Securities then outstanding.
    
 
EVENTS OF DEFAULT
 
     An event of default under each Guarantee will occur upon the failure of the
Corporation to perform any of its payment or other obligations thereunder. The
holders of not less than a majority in aggregate Liquidation Amount of the
related Preferred Securities have the right to direct the time, method and place
of conducting any proceeding for any remedy available to the Guarantee Trustee
in respect of such Guarantee or to direct the exercise of any trust or power
conferred upon the Guarantee Trustee under such Guarantee.
 
     Any holder of the Preferred Securities may institute a legal proceeding
directly against the Corporation to enforce its rights under such Guarantee
without first instituting a legal proceeding against the Issuer, the Guarantee
Trustee or any other person or entity.
 
     The Corporation, as guarantor, is required to file annually with the
Guarantee Trustee a certificate as to whether or not the Corporation is in
compliance with all the conditions and covenants applicable to it under the
Guarantee.
 
INFORMATION CONCERNING THE GUARANTEE TRUSTEE
 
     The Guarantee Trustee, other than during the occurrence and continuance of
a default by the Corporation in performance of any Guarantee, undertakes to
perform only such duties as are specifically set forth in each Guarantee and,
after default with respect to any Guarantee, must exercise the same degree of
care and skill as a prudent person would exercise or use in the conduct of his
or her own affairs. Subject to this provision, the Guarantee Trustee is under no
obligation to exercise any of the powers vested in it by any Guarantee at the
request of any holder of any Preferred Securities unless it is offered
reasonable indemnity against the costs, expenses and liabilities that might be
incurred thereby.
 
TERMINATION OF THE GUARANTEES
 
     Each Guarantee will terminate and be of no further force and effect upon
full payment of the Redemption Price of the related Preferred Securities, upon
full payment of the amounts payable upon liquidation of the related Issuer or
upon distribution of Corresponding Junior Subordinated Debentures to the holders
of the related Preferred Securities in exchange therefor. Each Guarantee will
continue to be effective or will be reinstated, as the case may be, if at any
time any holder of the related Preferred Securities must restore payment of any
sums paid under such Preferred Securities or such Guarantee.
 
GOVERNING LAW
 
     Each Guarantee will be governed by and construed in accordance with the
laws of the State of New York.
 
                                       41

                  RELATIONSHIP AMONG THE PREFERRED SECURITIES,
                THE CORRESPONDING JUNIOR SUBORDINATED DEBENTURES
                               AND THE GUARANTEES
 
FULL AND UNCONDITIONAL GUARANTEE
 
   
     Payments of Distributions and other amounts due on the Preferred Securities
(to the extent the Issuer has funds available for the payment of such
Distributions) are irrevocably guaranteed by the Corporation as and to the
extent set forth under "Description of Guarantees". Taken together, the
Corporation's obligations under each series of Corresponding Junior Subordinated
Debentures, the Indenture, the related Trust Agreement and the related Guarantee
provide, in the aggregate, a full, irrevocable and unconditional guarantee of
payments of distributions and other amounts due on the Related Preferred
Securities. No single document standing alone or operating in conjunction with
fewer than all of the other documents constitutes such guarantee. It is only the
combined operation of these documents that has the effect of providing a full,
irrevocable and unconditional guarantee of the Issuer's obligations under the
Related Preferred Securities. If and to the extent that the Corporation does not
make payments on any series of Corresponding Junior Subordinated Debentures,
such Issuer will not pay Distributions or other amounts due on the Related
Preferred Securities. The Guarantees do not cover payment of Distributions when
the related Issuer does not have sufficient funds to pay such Distributions. In
such event, the remedy of a holder of a series of Preferred Securities is to
institute a legal proceeding directly against the Corporation pursuant to the
terms of the Indenture for enforcement of payment of amounts equal to such
Distributions to such holder. The obligations of the Corporation under each
Guarantee are subordinate and junior in right of payment to all Senior
Indebtedness of the Corporation.
    
 
SUFFICIENCY OF PAYMENTS
 
     As long as payments of interest and other payments are made when due on
each series of Corresponding Junior Subordinated Debentures, such payments will
be sufficient to cover Distributions and other payments due on the Related
Preferred Securities, primarily because (i) the aggregate principal amount of
each series of Corresponding Junior Subordinated Debentures will be equal to the
sum of the aggregate stated Liquidation Amount of the Related Preferred
Securities and related Common Securities; (ii) the interest rate and interest
and other payment dates on each series of Corresponding Junior Subordinated
Debentures will match the Distribution rate and Distribution and other payment
dates for the Related Preferred Securities; (iii) the Holder of the Common
Securities shall pay for all and any costs, expenses and liabilities of such
Issuer except the Issuer's obligations to holders of its Preferred Securities
under such Preferred Securities; and (iv) each Trust Agreement further provides
that the Issuer will not engage in any activity that is not consistent with the
limited purposes of such Issuer.
 
     Notwithstanding anything to the contrary in the Indenture, the Corporation
has the right to set-off any payment it is otherwise required to make thereunder
with and to the extent the Corporation has theretofore made, or is concurrently
on the date of such payment making, a payment under the related Guarantee.
 
ENFORCEMENT RIGHTS OF HOLDERS OF PREFERRED SECURITIES
 
     A holder of any related Preferred Security may institute a legal proceeding
directly against the Corporation to enforce its rights under the related
Guarantee without first instituting a legal proceeding against the Guarantee
Trustee, the related Issuer or any other person or entity.
 
   
     A default or event of default under any Senior Indebtedness of the
Corporation would not constitute a default or Event of Default under the
Indenture. However, in the event of payment defaults under, or acceleration of,
Senior Indebtedness of the Corporation, the subordination provisions of the
Indenture provide that no payments may be made in respect of the Corresponding
    
 
                                       42
<PAGE>   73
 
   
Junior Subordinated Debentures until such Senior Indebtedness has been paid in
full or any payment default thereunder has been cured or waived. Failure to make
required payments on any series of Corresponding Junior Subordinated Debentures
would constitute a Debenture Event of Default under the Indenture.
    
 
LIMITED PURPOSE OF ISSUERS
 
     Each Issuer's Preferred Securities evidence a beneficial interest in such
Issuer, and each Issuer exists for the sole purpose of issuing its Preferred
Securities and Common Securities and investing the proceeds thereof in
Corresponding Junior Subordinated Debentures. A principal difference between the
rights of a holder of a Preferred Security and a holder of a Corresponding
Junior Subordinated Debenture is that a holder of a Corresponding Junior
Subordinated Debenture is entitled to receive from the Corporation the principal
amount of and interest accrued on Corresponding Junior Subordinated Debentures
held, while a holder of Preferred Securities is entitled to receive
Distributions from such Issuer (or from the Corporation under the applicable
Guarantee) if and to the extent such Issuer has funds available for the payment
of such Distributions.
 
RIGHTS UPON TERMINATION
 
     Upon any voluntary or involuntary termination, winding up or liquidation of
any Issuer involving the liquidation of the Corresponding Junior Subordinated
Debentures, the holders of the related Preferred Securities will be entitled to
receive, out of the assets held by such Issuer, the Liquidation Distribution in
cash. See "Description of Preferred Securities -- Liquidation Distribution Upon
Termination". Upon any voluntary or involuntary liquidation or bankruptcy of the
Corporation, the Property Trustee, as holder of the Corresponding Junior
Subordinated Debentures, would be a subordinated creditor of the Corporation,
subordinated in right of payment to all Senior Indebtedness as set forth in the
Indenture, but entitled to receive payment in full of principal and interest,
before any stockholders of the Corporation receive payments or distributions.
Since the Corporation is the guarantor under each Guarantee and the Holder of
the Common Securities is obligated to pay for all costs, expenses and
liabilities of each Issuer (other than the Issuer's obligations to the holders
of its Preferred Securities), the positions of a holder of such Preferred
Securities and a holder of such Corresponding Junior Subordinated Debentures
relative to other creditors and to stockholders of the Corporation in the event
of liquidation or bankruptcy of the Corporation are expected to be substantially
the same.
 
                              PLAN OF DISTRIBUTION
 
     The Junior Subordinated Debentures or the Preferred Securities may be sold
in a public offering to or through underwriters or dealers designated from time
to time. The Corporation and each Issuer may sell its Junior Subordinated
Debentures or Preferred Securities as soon as practicable after effectiveness of
the Registration Statement of which this Prospectus forms a part. The names of
any underwriters or dealers involved in the sale of the Junior Subordinated
Debentures or Preferred Securities in respect of which this Prospectus is
delivered, the amount or number of Junior Subordinated Debentures and Preferred
Securities to be purchased by any such underwriters and any applicable
commissions or discounts will be set forth in the applicable Prospectus
Supplement.
 
     Underwriters may offer and sell Junior Subordinated Debentures or Preferred
Securities at a fixed price or prices, which may be changed, or from time to
time at market prices prevailing at the time of sale, at prices related to such
prevailing market prices or at negotiated prices. In connection with the sale of
Preferred Securities, underwriters may be deemed to have received compensation
from the Corporation and/or the applicable Issuer in the form of underwriting
discounts or commissions and may also receive commissions. Underwriters may sell
Junior Subordinated Debentures or Preferred Securities to or through dealers,
and such dealers may receive compensation in the form of discounts, concessions
or commissions from the underwriters.
 
                                       43
<PAGE>   74
 
   
     Any underwriting compensation paid by the Corporation and/or the applicable
Issuer to underwriters or dealers in connection with the offering of Junior
Subordinated Debentures or Preferred Securities, and any discounts, concessions
or commissions allowed by such underwriters to participating dealers, will be
described in an accompanying Prospectus Supplement. Underwriters and dealers
participating in the distribution of Junior Subordinated Debentures or Preferred
Securities may be deemed to be underwriters, and any discounts and commissions
received by them and any profit realized by them on resale of such Junior
Subordinated Debentures or Preferred Securities may be deemed to be underwriting
discounts and commissions, under the Securities Act.
    
 
     In connection with the offering of the Preferred Securities of any Issuer,
such Issuer may grant to the underwriters an option to purchase additional
Preferred Securities to cover over-allotments, if any, at the initial public
offering price (with an additional underwriting commission), as may be set forth
in the accompanying Prospectus Supplement. If such Issuer grants any
over-allotment option, the terms of such over-allotment option will be set forth
in the Prospectus Supplement for such Preferred Securities.
 
   
     The Corporation and each Issuer may also sell their Junior Subordinated
Debentures or Preferred Securities directly to purchasers or through agents. In
such case, offers to purchase Junior Subordinated Debentures or Preferred
Securities may be solicited directly by the Corporation or an Issuer, or by
agents designated by the Corporation or an Issuer. Any such agent, who may be
deemed to be an underwriter, as that term is defined in the Securities Act,
involved in the offer and sale of such securities in respect of which this
Prospectus is delivered will be named, and any commission payable by the
Corporation or the applicable Issuer to such agent will be set forth in the
applicable Prospectus Supplement.
    
 
   
     Underwriters, dealers and agents may be entitled, under agreements with the
Corporation and the applicable Issuer, to indemnification against and
contribution toward certain civil liabilities, including liabilities under the
Securities Act, and to reimbursement by the Corporation for certain expenses.
    
 
   
     Underwriters, dealers, and agents may engage in transactions with, or
perform services for, the Corporation and/or the applicable Issuer and/or any of
their affiliates in the ordinary course of business.
    
 
     The Junior Subordinated Debentures and the Preferred Securities will be new
issues of securities and will have no established trading market. Any
underwriters to whom Junior Subordinated Debentures or Preferred Securities are
sold for public offering and sale may make a market in such Junior Subordinated
Debentures and Preferred Securities, but such underwriters will not be obligated
to do so and may discontinue any market making at any time without notice. Such
Junior Subordinated Debentures or Preferred Securities may or may not be listed
on a national securities exchange or the Nasdaq National Market. No assurance
can be given as to the liquidity of or the existence of trading markets for any
Junior Subordinated Debentures or Preferred Securities.

                             VALIDITY OF SECURITIES
 
   
     Unless otherwise indicated in the applicable Prospectus Supplement, certain
legal matters will be passed upon for the Corporation by Sullivan & Cromwell,
counsel to the Corporation, and for the Issuers by Richards, Layton & Finger,
special Delaware counsel to the Issuers and the Corporation. Certain other
matters will be passed upon for the Corporation by Harry A. Johnson, III, Esq.,
Executive Vice President and General Counsel of the Corporation. The validity of
the Guarantees and the Junior Subordinated Debentures will be passed upon for
the Corporation by Sullivan & Cromwell and for the Underwriters by Simpson
Thacher & Bartlett. Sullivan & Cromwell and Simpson Thacher & Bartlett will rely
on the opinion of Richards, Layton & Finger as to matters of Delaware law and on
the opinion of Mr. Johnson as to matters of Tennessee Law. At December 2, 1996,

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Tennessee Code Annotated, Sections 48-18-501 through 48-18-509 authorizes a
corporation to provide for the indemnification of officers, directors, employees
and agents in terms sufficiently broad to permit indemnification under certain
circumstances for liabilities (including reimbursement for expenses incurred)
arising under the Securities Act of 1933, as amended. The Corporation has
adopted the provisions of the Tennessee statute pursuant to Article XXVIII of
its Bylaws. Also, the Corporation has a Directors' and Officers' Liability
Insurance Policy which provides coverage sufficiently broad to permit
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1931,
as amended.
 
     Tennessee Code Annotated Section 48-12-102 permits the inclusion in the
charter of a Tennessee corporation of a provision, with certain exceptions,
eliminating the personal monetary liability of directors to the corporation or
its shareholders for breach of the duty of care. The Corporation has adopted the
provisions of the statute in Article 13 of its charter.
 
     The shareholders of the Corporation have approved an amendment to Article
XXVIII of the Bylaws pursuant to which the Corporation is required to indemnify
each director and any officers designated by the Corporation's Board of
Directors, and advance expenses, to the maximum extent not prohibited by law. In
accordance with the foregoing, the Board is authorized to enter into individual
indemnity agreements with the directors and such officers. Such indemnity
agreements have been approved for all of the directors and certain officers.
 
     Reference is also made to the Underwriting Agreement filed as an Exhibit
hereto, for provisions regarding indemnification of the registrant's officers
and directors against certain liabilities.
 
     Under the Trust Agreement, the Corporation will agree to indemnify each of
the Trustees of the Issuer or any predecessor Trustee for the Issuer, and to
hold the Trustee harmless against, any loss, damage, claims, liability or
expense incurred without negligence or bad faith on its part, arising out of or
in connection with the acceptance or administration of the Trust Agreements,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties under the Trust Agreements.

ITEM 17.  UNDERTAKINGS.
 
     Each of the undersigned Registrants hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of a Registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934 that is incorporated by reference
in this Registration Statement shall be deemed to be a new registration
statement relating to the securities offered herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering
thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of each
Registrant pursuant to the provisions described under Item 15 above, or
otherwise, each Registrant has been advised that in the opinion
 
                                      II-3
<PAGE>   80
 
of the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by each Registrant of expenses incurred or paid by a director, officer
or controlling person of each Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, each Registrant will,
unless in the opinion of its counsel the matter has been settled by the
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
Each of the undersigned Registrants hereby also undertakes:
 
     (1) to file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:
 
          (i) to include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;
 
          (ii) to reflect in the prospectus any facts or events arising after
     the effective date of this Registration Statement (or the most recent
     post-effective amendment thereto) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in this
     Registration Statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective registration statement; and
 
          (iii) to include any material information with respect to the plan of
     distribution not previously disclosed in this Registration Statement or any
     material change to such information in this Registration Statement;
 
provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by a Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in this
Registration Statement.
 
     (2) that, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     (3) to remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.
 
     (4) to provide to the underwriter at the closing specified in the
underwriting agreement certificates in such denominations and registered in such
names as required by the underwriter to permit prompt delivery to each
purchaser.
 
     (5) That, for the purposes of determining any liability under the
Securities Act of 1933:
 
          (i) The information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     the form of prospectus filed by the Registrants pursuant to Rule 424(b)(1)
     or (4) or 497(h) under the Securities Act shall be deemed to be part of
     this Registration Statement as of the time it was declared effective.
 
          (ii) Each post-effective amendment that contains a form of prospectus
     shall be deemed to be a new Registration Statement relating to the
     securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

Registrant certifies that it has reasonable grounds to believe that it meets all
of the requirements for filing on Form S-3 and has duly caused this Amendment to
the Registration Statement to be signed on its behalf by the undersigned,

instrument or of a writing appointing any such agent or proxy shall be
sufficient for any purpose of this Indenture and (subject to Section 6.1)

provided in this Section.

manner which the Trustee deems sufficient and in accordance with such reasonable
rules as the Trustee may determine.

         (d) The ownership of Securities shall be proved by the Securities
Register.

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

         (f) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to give, make or take
any request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Indenture to be given, made or taken by
Holders of Securities of such series, provided that the Company may not set a
record date for, and the provisions of this paragraph shall not apply with
respect to, the giving or making of any notice, declaration, request or
direction referred to in the next paragraph. If any record date is set pursuant
to this paragraph, the Holders of the relevant Outstanding Securities on such
record date, and no other Holders, shall be entitled to take the relevant
action, whether or not such Holders remain Holders after such record date,
provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal
amount of the relevant Outstanding Securities on such record date. Nothing in
this paragraph shall be construed to prevent the Company from setting a new
record date for any action for which a record date has previously been set
pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect),
and nothing in this paragraph shall be construed to render ineffective any
action taken by Holders of the requisite principal amount of the relevant
Outstanding Securities on the date such action is taken. Promptly after any
record date is set pursuant to this paragraph, the Company, at its own expense,
shall cause notice of such record date, the proposed action by Holders and the
applicable Expiration Date to be given to the Trustee in writing and to each
Holder of the relevant Securities in the manner set forth in Section 1.6.

         The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities entitled to join in the giving
or making of (i) any Notice of Default, (ii) any declaration of acceleration
referred to in Section 5.2, (iii) any request to institute proceedings referred
to in Section 5.7(2) or (iv) any direction referred to in Section 5.12, in each
case with respect to the relevant Securities. If any record date is set pursuant
to this paragraph, the Holders of the relevant Outstanding Securities on such
record date, and no other Holders, shall be entitled to join in such notice,
declaration, request or direction, whether or not such Holders remain Holders
after such record date, provided that no such action shall be effective
hereunder unless taken on or prior to the applicable Expiration Date by Holders
of the requisite principal amount of the relevant Outstanding Securities on such
record date. Nothing in this paragraph shall be construed to prevent the Trustee
from setting a new record date for any action for which a record date has
previously been set pursuant to this paragraph (whereupon the record date
previously set shall automatically and with no action by any Person

                                                                              13



be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of the relevant Outstanding Securities on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Trustee,
at the Company's expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be given to the Company
in writing and to each Holder of the relevant Securities in the manner set forth
in Section 1.6.

         With respect to any record date set pursuant to this Section, the party
hereto which sets such record date may designate any day as the "Expiration
Date" and from time to time may change the Expiration Date to any earlier or
later day, provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to the other party hereto in writing, and
to each Holder of the relevant Outstanding Securities in the manner set forth in
Section 1.6, on or prior to the existing Expiration Date. If an Expiration Date
is not designated with respect to any record date set pursuant to this Section,
the party hereto which set such record date shall be deemed to have initially
designated the 180th day after such record date as the Expiration Date with
respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be
later than the 180th day after the applicable record date.

         (g) Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such 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 principal amount.

         SECTION 1.5.   Notices, Etc. to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

         (1) the Trustee by any Holder, any holder of Preferred Securities or
the Company shall be sufficient for every purpose hereunder if made, given,
furnished or filed in writing to or with the Trustee at its Corporate Trust
Office, or

         (2) the Company by the Trustee, any Holder or any holder of Preferred
Securities shall be sufficient for every purpose (except as otherwise provided
in Section 5.1) hereunder if in writing and mailed, first class, postage
prepaid, to the Company addressed to it at the address of its principal office
specified in the first paragraph of this instrument or at any other address
previously furnished in writing to the Trustee by the Company.

         SECTION 1.6.   Notice to Holders; Waiver.

         Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first class postage prepaid, to each Holder affected
by such event, at the address of such Holder as it appears in the Securities
Register, not later than the latest date, and not earlier than the earliest
date, prescribed for the giving of such notice. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

         SECTION 1.7.   Conflict with Trust Indenture Act.

         If any provision of this Indenture limits, qualifies or conflicts with
the duties imposed by any of Sections 310 to 317, inclusive, of the Trust
Indenture Act through operation of Section 318(c) thereof, such imposed duties
shall control.

         SECTION 1.8.   Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         SECTION 1.9.   Successors and Assigns.

         All covenants and agreements in this Indenture by the Company shall
bind its successors and assigns, whether so expressed or not.

         SECTION 1.10.  Separability Clause.

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

         SECTION 1.11   Benefits of Indenture.

         Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors and
assigns, the holders of Senior Indebtedness, the Holders of the Securities and,
to the extent expressly provided in Sections 5.2, 5.8, 5.9, 5.11, 5.13, 9.1 and
9.2, the holders of Preferred Securities, any benefit or any legal or equitable
right, remedy or claim under this Indenture.

from and after such Interest Payment Date, Redemption Date or Stated Maturity,
as the case may be, until such next succeeding Business Day) except that, if
such Business Day is in the next succeeding calendar year, such payment shall be
made on the immediately preceding Business Day (in each case with the same force
and effect as if made on the Interest Payment Date or Redemption Date or at the
Stated Maturity).

No.              $

         FIRST TENNESSEE NATIONAL CORPORATION, a corporation organized and
existing under the laws of the state of Tennessee (hereinafter called the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to     
   , or registered assigns, the principal sum of
              Dollars on __________ __, ____[; provided that the Company may,
subject to certain conditions set forth in Section 3.14 of the Indenture, (i)
shorten the Stated Maturity of the principal of this Security to a date not
earlier than __________, and (ii) extend the Stated Maturity of the principal of
this Security at any time on one or more occasions, but in no event to a date
later than __________]. The Company further promises to pay interest on said
principal sum from , or from the most recent interest payment date (each such
date, an "Interest Payment Date") on which interest has been paid or duly
provided for, [monthly] [quarterly] [semi-annually] [if applicable, insert -
(subject to deferral as set forth herein)] in arrears on [insert applicable
Interest Payment Dates] of each year, commencing,        , at the rate of
% per annum, until the principal hereof shall have become due and payable, [if 
applicable, insert plus Additional Interest, if any,] until the principal
hereof is paid or duly provided for or made available for payment
[if applicable, insert - and on any overdue principal and (without
duplication and to the extent that payment of such interest is enforceable under
applicable law) on any overdue installment of interest at the rate of % per
annum, compounded [monthly] [quarterly] [semi-annually]. The amount of interest
payable for any period shall be computed on the basis of twelve 30-day months
and a 360-day year. The amount of interest payable 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. In the event that any date on which interest is payable on
this Security is not a Business Day, then a payment of the interest payable on
such date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay), except
that, if such Business Day is in the next succeeding calendar year, such payment
shall be made on the immediately preceding Business Day, in each case with the
same force and effect as if made on the date the payment was originally payable.
A "Business Day" shall mean any day other than (i) a Saturday or Sunday, (ii) a
day on which banking institutions in The City of New York are authorized or
required by law or executive order to remain closed or (iii) a day on which the
Corporate Trust Office of the Trustee [if applicable, insert - or the principal
office of the Property Trustee under the Trust Agreement hereinafter referred to
for First Tennessee Capital _,] is closed for business. The interest installment
so payable, and punctually paid or duly provided for, on any Interest Payment
Date will, as provided in the Indenture, be paid to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the close
of business on the Regular Record Date for such interest installment, which
shall be the [insert definition of Regular Record Dates]. Any such interest
installment not so punctually paid or duly provided

for shall forthwith cease to be payable to the Holder on such Regular Record
Date and may either be paid to the Person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on a Special
Record Date for the payment of such Defaulted Interest to be fixed by the
Trustee, notice whereof shall be given to Holders of Securities of this series
not less than 10 days prior to such Special Record Date, or be paid at any time
in any other lawful manner not inconsistent with the requirements of any
securities exchange or automated quotation system on which the Securities of
this series may be listed or traded, and upon such notice as may be required by
such exchange or self-regulatory organization, all as more fully provided in
said Indenture.

         [If applicable, insert - So long as no Event of Default has occurred
and is continuing, the Company shall have the right at any time during the term
of this Security to defer payment of interest on this Security, at any time or
from time to time, for up to consecutive [monthly] [quarterly] [semi-annual]
interest payment periods with respect to each deferral period (each an
"Extension Period"), during which Extension Periods the Company shall have the
right to make partial payments of interest on any Interest Payment Date, and at
the end of which the Company shall pay all interest then accrued and unpaid
(together with Additional Interest thereon to the extent permitted by applicable
law); provided, however, that no Extension Period shall extend beyond the Stated
Maturity of the principal of this Security; provided, further, that during any
such Extension Period, the Company shall not, and shall not permit any
Subsidiary of the Company to, (i) declare or pay any dividends or distributions
on or redeem, purchase, acquire or make a liquidation payment with respect to,
any of the Company's capital stock or (ii) make any payment of principal of or
interest or premium, if any, on or repay, repurchase or redeem any debt security
of the Company that ranks pari passu with or junior in interest to this Security
or (iii) make any guarantee payments with respect to any guarantee by the
Company of the debt securities of any Subsidiary of the Company if such
guarantee ranks pari passu with or junior in interest to this Security (other

declaration of a dividend in connection with the implementation of a Rights Plan
or the redemption or repurchase of any rights distributed pursuant to a Rights
Plan, (c) payments under the Guarantee with respect to this Security, and (d)
purchases of Common Stock related to the issuance of Common Stock or rights or

to the issuance of Common Stock or rights under a dividend reinvestment and
stock purchase plan, or related to the issuance of Common Stock (or securities
convertible or exchangeable for Common Stock) as consideration in an acquisition
transaction that was entered into prior to the commencement of such Extension
Period). Prior to the termination of any such Extension Period, the Company may
further defer the payment of interest, provided that no Extension Period shall
exceed __ consecutive [months] [quarters] [semi-annual periods] or extend beyond
the Stated Maturity of the principal of this Security. Upon the termination of
any such Extension Period and upon the payment of all accrued and unpaid
interest and any Additional Interest then due, the Company may elect to begin a
new Extension Period, subject to the above requirements. No interest shall be
due and payable during an Extension Period except at the end thereof. The
Company shall give the Holder of this Security and the Trustee notice of its
election to begin any Extension Period at least one Business Day prior to the
next succeeding Interest Payment Date on which interest on this Security would
be payable but for such deferral [if applicable, insert - or, with respect to
the Securities issued to a Trust, so long as such Securities

deferral or (ii) the date the Administrative Trustees are required to give
notice to any securities exchange or other applicable self-regulatory
organization or to holders of such Preferred Securities of the record date or
the date such Distributions are payable, but in any event not less than one
Business Day prior to such record date]].

         Payment of principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in the United States, in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts [if applicable, insert -; provided, however, that at the option of
the Company payment of interest may be made (i) by check mailed to the address
of the Person entitled thereto as such address shall appear in the Securities
Register or (ii) by wire transfer or direct deposit in immediately available
funds at such place and to such account as may be designated in writing by the
relevant Regular Record Date by the Person entitled thereto as specified in the
Securities Register].

         The indebtedness evidenced by this Security is, to the extent provided
in the Indenture, subordinate and subject in right of payment to the prior
payment in full of all Senior Indebtedness, and this Security is issued subject
to the provisions of the Indenture with respect thereto. Each Holder of this
Security, by accepting the same, (a) agrees to and shall be bound by such
provisions, (b) authorizes and directs the Trustee on his behalf to take such
actions as may be necessary or appropriate to effectuate the subordination so
provided and (c) appoints the Trustee his attorney-in-fact for any and all such
purposes. Each Holder hereof, by his acceptance hereof, waives all notice of the
acceptance of the subordination provisions contained herein and in the Indenture
by each holder of Senior Indebtedness, whether now outstanding or hereafter
incurred, and waives reliance by each such holder upon said provisions.

         Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

the Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

executed under its corporate seal.

indentures for the purpose of modifying in any manner the rights and obligations
of the Company and of the Holders of the Securities, with the consent of the
Holders of not less than a majority in principal amount of the Outstanding
Securities of all series to be affected by such supplemental indenture. The
Indenture also contains provisions permitting Holders of specified percentages
in principal amount of the Securities of all series at the time Outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences. Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and

than 25% in principal amount of the Outstanding Securities of this series may
declare the principal amount of all the Securities of this series to be due and
payable immediately, by a notice in writing to the Company (and to the Trustee
if given by Holders), provided that, in the case of the Securities of this
series issued to a Trust, if upon an Event of Default, the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of this series fails to declare the principal of all the Securities of this
series to be immediately due and payable, the holders of at least 25% in
aggregate Liquidation Amount of the Preferred Securities then outstanding shall
have such right by a notice in writing to the Company and the Trustee; and upon

         Securities bearing the manual or facsimile signatures of individuals
who were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such

Securities of any series executed by the Company to the Trustee for
authentication,


<PAGE>   33


                                                                              26



together with a Company Order for the authentication and delivery of such
Securities, and the Trustee in accordance with the Company Order shall
authenticate and make such Securities available for delivery. If the form or
terms of the Securities of the series have been established by or pursuant to
one or more Board Resolutions as permitted by Sections 2.1 and 3.1, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 6.1) shall be fully protected in
relying upon, an Opinion of Counsel stating,

                  (1) if the form of such Securities has been established by or
         pursuant to Board Resolution as permitted by Section 2.1, that such
         form has been established in conformity with the provisions of this
         Indenture;

                  (2) if the terms of such Securities have been established by
         or pursuant to Board Resolution as permitted by Section 3.1, that such
         terms have been established in conformity with the provisions of this
         Indenture;

                  (3) that such Securities, when authenticated and delivered by
         the Trustee and issued by the Company in the manner and subject to any
         conditions specified in such Opinion of Counsel, will constitute valid
         and legally binding obligations of the Company enforceable in
         accordance with their terms, subject to bankruptcy, insolvency,
         fraudulent transfer, reorganization, moratorium and similar laws of
         general applicability relating to or affecting creditors' rights and to
         general equity principles; and

                  (4) that all requirements of New York and Federal law and the
         Tennessee Business Corporation Act in respect of the execution and
         delivery by the Company of such Securities, and all covenants and
         conditions set forth in this Indenture which are conditions precedent
         hereto, have been complied with.

If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties or
immunities under the Securities and this Indenture or otherwise in a manner
which is not reasonably acceptable to the Trustee.

                  Notwithstanding the provisions of Section 3.1 and of the
preceding paragraph, if all Securities of a series are not to be originally
issued at one time, it shall not be necessary to deliver the Officers'
Certificate otherwise required pursuant to Section 3.1 or the Company Order and
Opinion of Counsel otherwise required pursuant to such preceding paragraph at or
prior to the authentication of each Security of such series if such documents
are delivered at or prior to the authentication upon original issuance of the
first Security of such series to be issued.

         Each Security shall be dated the date of its authentication.

         No Security shall be entitled to any benefit under this Indenture or be
valid or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form provided for herein
executed by the Trustee by the manual signature of one of its authorized
signatories, and such certificate upon any Security shall be conclusive
evidence, and the only evidence, that such Security has been duly authenticated
and delivered hereunder.

                                                                              27



Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company
shall deliver such Security to the Trustee for cancellation as provided in
Section 3.9, for all purposes of this Indenture such Security shall be deemed
never to have been authenticated and delivered hereunder and shall not be
entitled to the benefits of this Indenture.

         SECTION 3.4.   Temporary Securities.

         Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
make available for delivery, temporary Securities which are printed,
lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the definitive Securities of such
series in lieu of which they are issued and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as evidenced by their execution of such Securities.

        If temporary Securities of any series are issued, the Company will cause
definitive Securities of such series to be prepared without unreasonable delay.
After the preparation of definitive Securities, the temporary Securities shall
be exchangeable for definitive Securities upon surrender of the temporary
Securities at the office or agency of the Company designated for that purpose
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Securities, the Company shall execute and the Trustee shall
authenticate and make available for delivery in exchange therefor one or more
definitive Securities of the same series, of any authorized denominations, or
like aggregate principal amount, having the same Original Issue Date and Stated
Maturity and having the same terms as such temporary Securities. Until so
exchanged, the temporary Securities of any series shall in all respects be
entitled to the same benefits under this Indenture as definitive Securities of
such series.

         SECTION 3.5.   Registration, Transfer and Exchange.

         The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of Securities and of
transfers of Securities. Such register is herein sometimes referred to as the
"Securities Register." The Trustee is hereby appointed "Securities Registrar"
for the purpose of registering Securities and transfers of Securities as herein
provided.


         Upon surrender for registration of transfer of any Security at the
office or agency of the Company designated for that purpose the Company shall
execute, and the Trustee shall authenticate and make available for delivery, in
the name of the designated transferee or transferees, one or more new Securities
of the same series of any authorized denominations, of a like aggregate
principal amount, of the same Original Issue Date and Stated Maturity and having
the same terms.

         At the option of the Holder, Securities may be exchanged for other
Securities of the same series of any authorized denominations, of a like
aggregate principal amount, of the same Original Issue Date and Stated Maturity
and having the same terms, upon surrender of the


<PAGE>   35


                                                                              28



Securities to be exchanged at such office or agency. Whenever any Securities are
so surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and make available for delivery, the Securities which the Holder
making the exchange is entitled to receive.

         All Securities issued upon any transfer or exchange of Securities shall
be the valid obligations of the Company, evidencing the same debt, and entitled
to the same benefits under this Indenture, as the Securities surrendered upon
such transfer or exchange.

         Every Security presented or surrendered for transfer or exchange shall
(if so required by the Company or the Securities Registrar) be duly endorsed, or
be accompanied by a written instrument of transfer in form satisfactory to the
Company and the Securities Registrar, duly executed by the Holder thereof or his
attorney duly authorized in writing.

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

                  The provisions of Clauses (1), (2), (3) and (4) below shall 
apply only to Global Securities:

                  (1) Each Global Security authenticated under this Indenture
         shall be registered in the name of the Depositary designated for such
         Global Security or a nominee thereof and delivered to such Depositary
         or a nominee thereof or custodian therefor, and each such Global
         Security shall constitute a single Security for all purposes of this
         Indenture.

                  (2) Notwithstanding any other provision in this Indenture, no
         Global Security may be exchanged in whole or in part for Securities
         registered, and no transfer of a Global Security in whole or in part
         may be registered, in the name of any Person other than the Depositary
         for such Global Security or a nominee thereof unless (A) such
         Depositary (i) has notified the Company that it is unwilling or unable
         to continue as Depositary for such Global Security or (ii) has ceased
         to be a clearing agency registered under the Exchange Act at a time
         when the Depositary is required to be so registered to act as
         depositary, in either case unless the Company has approved a successor
         Depositary within 90 days, (B) there shall have occurred and be
         continuing an Event of Default with respect to such Global Security,
         (C) the Company in its sole discretion determines that such Global
         Security will be so exchangeable or transferable or (D) there shall
         exist such circumstances, if any, in addition to or in lieu of the
         foregoing as have been specified for this purpose as contemplated by
         Section 3.1.

                  (3) Subject to Clause (2) above, any exchange of a Global
         Security for other Securities may be made in whole or in part, and all
         Securities issued in exchange for a Global Security or any portion
         thereof shall be registered in such names as the Depositary for such
         Global Security shall direct.

                  (4) Every Security authenticated and delivered upon
         registration of transfer of, or in exchange for or in lieu of, a Global
         Security or any portion thereof, whether


<PAGE>   36


                                                                              29



         pursuant to this Section, Section 3.4, 3.6, 9.6 or 11.6 or otherwise,
         shall be authenticated and delivered in the form of, and shall be, a
         Global Security, unless such Security is registered in the name of a
         Person other than the Depositary for such Global Security or a nominee
         thereof.

         Neither the Company nor the Trustee shall be required, pursuant to the
provisions of this Section, (a) to issue, transfer or exchange any Security of
any series during a period beginning at the opening of business 15 days before
the mailing of notice of redemption of Securities pursuant to Article XI and
ending at the close of business on the day of such mailing of notice of
redemption or (b) to transfer or exchange any Security selected for redemption
in whole or in part, except, in the case of any Security to be redeemed in part,
any portion thereof not to be redeemed.

         SECTION 3.6.   Mutilated, Destroyed, Lost and Stolen Securities.

         If any mutilated Security is surrendered to the Trustee together with
such security or indemnity as may be required by the Company or the Trustee to
hold each of them harmless, the Company shall execute and the Trustee shall
authenticate and make available for delivery in exchange therefor a new Security
of the same issue and series of like tenor and principal amount, having the same
Original Issue Date and Stated Maturity and bearing the same interest rate as
such mutilated Security, and bearing a number not contemporaneously outstanding.

         If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any
Security, and (ii) such security or indemnity as may be required by them to hold
each of them harmless, then, in the absence of notice to the Company or the
Trustee that such Security has been acquired by a bona fide purchaser, the
Company shall execute and upon its request the Trustee shall authenticate and
make available for delivery, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same issue and series of like tenor and
principal amount, having the same Original Issue Date and Stated Maturity and
bearing the same interest rate as such destroyed, lost or stolen Security, and
bearing a number not contemporaneously outstanding.

         In case any such mutilated, destroyed, lost or stolen Security has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Security, pay such Security.

         Upon the issuance of any new Security under this Section, the Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

         Every new Security issued pursuant to this Section in lieu of any
destroyed, lost or stolen Security shall constitute an original additional
contractual obligation of the Company, whether or not the destroyed, lost or
stolen Security shall be at any time enforceable by anyone, and shall be
entitled to all the benefits of this Indenture equally and proportionately with
any and all other Securities of that series duly issued hereunder.

                                                                              30



         The provisions of this Section are exclusive and shall preclude (to the
extent lawful) all other rights and remedies with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities.

         SECTION 3.7.   Payment of Interest; Interest Rights Preserved.

         Interest on any Security of any series which is payable, and is
punctually paid or duly provided for, on any Interest Payment Date, shall be
paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest in respect of Securities of such series, except that, unless
otherwise provided in the Securities of such series, interest payable on the
Stated Maturity of the principal of a Security shall be paid to the Person to
whom principal is paid. The initial payment of interest on any Security of any
series which is issued between a Regular Record Date and the related Interest
Payment Date shall be payable as provided in such Security or in the Board
Resolution pursuant to Section 3.1 with respect to the related series of
Securities. At the option of the Company, interest on any series of Securities
may be paid (i) by check mailed to the address of the Person entitled thereto as
it shall appear on the Securities Register of such series or (ii) by wire
transfer or direct deposit in immediately available funds at such place and to
such account as designated by the Person entitled thereto as specified in the
Securities Register of such series, provided that proper transfer instructions
have been received prior to the relevant Regular Record Date.

         Any interest on any Security which is payable, but is not timely paid
or duly provided for, on any Interest Payment Date for Securities of such series
(herein called "Defaulted Interest"), shall forthwith cease to be payable to the
registered Holder on the relevant Regular Record Date by virtue of having been
such Holder, and such Defaulted Interest may be paid by the Company, at its
election in each case, as provided in Clause (1) or (2) below:

         (1) The Company may elect to make payment of any Defaulted Interest to
the Persons in whose names the Securities of such series in respect of which
interest is in default (or their respective Predecessor Securities) are
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest, which shall be fixed in the following manner. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each Security and the date of the proposed payment, and
at the same time the Company shall deposit with the Trustee an amount of money
equal to the aggregate amount proposed to be paid in respect of such Defaulted
Interest or shall make arrangements satisfactory to the Trustee for such deposit
prior to the date of the proposed payment, such money when deposited to be held
in trust for the benefit of the Persons entitled to such Defaulted Interest as
in this Clause provided. Thereupon the Trustee shall fix a Special Record Date
for the payment of such Defaulted Interest which shall be not more than 15 days
and not less than 10 days prior to the date of the proposed payment and not less
than 10 days after the receipt by the Trustee of the notice of the proposed
payment. The Trustee shall promptly notify the Company of such Special Record
Date and, in the name and at the expense of the Company, shall cause notice of
the proposed payment of such Defaulted Interest and the Special Record Date
therefor to be mailed, first class, postage prepaid, to each Holder of a
Security of such series at the address of such Holder as it appears in the
Securities Register not less than 10 days prior to such Special Record Date. The
Trustee may, in its discretion, in the name and at the expense of the


<PAGE>   38


                                                                              31



Company, cause a similar notice to be published at least once in a newspaper,
customarily published in the English language on each Business Day and of
general circulation in the Borough of Manhattan, The City of New York, but such
publication shall not be a condition precedent to the establishment of such
Special Record Date. Notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor having been mailed as aforesaid, such
Defaulted Interest shall be paid to the Persons in whose names the Securities of
such series (or their respective Predecessor Securities) are registered on such
Special Record Date and shall no longer be payable pursuant to the following
Clause (2).

         (2) The Company may make payment of any Defaulted Interest in any other
lawful manner not inconsistent with the requirements of any securities exchange
or automated quotation system on which the Securities of the series in respect
of which interest is in default may be listed or traded and, upon such notice as
may be required by such exchange (or by the Trustee if the Securities are not
listed), if, after notice given by the Company to the Trustee of the proposed
payment pursuant to this Clause, such payment shall be deemed practicable by the
Trustee.

         Any interest on any Security which is deferred or extended pursuant to
Section 3.11 shall not be Defaulted Interest for the purposes of this Section
3.7.

         Subject to the foregoing provisions of this Section, each Security
delivered under this Indenture upon transfer of or in exchange for or in lieu of
any other Security shall carry the rights to interest accrued and unpaid, and to
accrue, which were carried by such other Security.

         SECTION 3.8.   Persons Deemed Owners.

         The Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name any Security is registered as the owner of
such Security for the purpose of receiving payment of principal of and (subject
to Section 3.7) any interest on such Security and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

         SECTION 3.9.   Cancellation.

         All Securities surrendered for payment, redemption, transfer or
exchange shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee, and any such Securities and Securities surrendered
directly to the Trustee for any such purpose shall be promptly canceled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly canceled by the Trustee. No Securities shall be authenticated
in lieu of or in exchange for any Securities canceled as provided in this
Section, except as expressly permitted by this Indenture. All canceled
Securities shall be returned by the Trustee to the Company and destroyed by the
Company.

         SECTION 3.10.   Computation of Interest.


<PAGE>   39


                                                                              32




         Except as otherwise specified as contemplated by Section 3.1 for
Securities of any series, interest on the Securities of each series for any
period shall be computed on the basis of a 360- day year of twelve 30-day months
and interest on the Securities of each series 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.

         SECTION 3.11.   Deferrals of Interest Payment Dates.

         If specified as contemplated by Section 2.1 or Section 3.1 with respect
to the Securities of a particular series, so long as no Event of Default has
occurred and is continuing, the Company shall have the right, at any time during
the term of such series, from time to time to defer the payment of interest on
such Securities for such period or periods as may be specified as contemplated
by Section 3.1 (each, an "Extension Period") during which Extension Periods the
Company shall have the right to make partial payments of interest on any
Interest Payment Date. No Extension Period shall end on a date other than an
Interest Payment Date. At the end of any such Extension Period the Company shall
pay all interest then accrued and unpaid on the Securities (together with
Additional Interest thereon, if any, at the rate specified for the Securities of
such series to the extent permitted by applicable law) to the Persons in whose
names that Securities are registered at the close of business on the Regular
Record Date with respect to the Interest Payment Date at the end of such
Extension Period; provided, however, that no Extension Period shall extend
beyond the Stated Maturity of the principal of the Securities of such series;
provided, further, that during any such Extension Period, the Company shall not,
and shall not permit any Subsidiary to, (i) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment
with respect to, any of the Company's capital stock, (ii) make any payment of
principal of or interest or premium, if any, on or repay, repurchase or redeem
any debt security of the Company that ranks pari passu with or junior in
interest to the Securities of such series or (iii) make any guarantee payments
with respect to any guarantee by the Company of the debt securities of any
Subsidiary of the Company that by their terms rank pari passu with or junior in
interest to the securities of such series (other than (a) dividends or
distributions in the Company's capital stock, (b) any declaration of a dividend
in connection with the implementation of a Rights Plan, or the redemption or
repurchase of any rights distributed pursuant to a Rights Plan, (c) payments
under the Guarantee with respect to such Security, and (d) purchases of Common
Stock related to the issuance of Common Stock or rights or options under any of
the Company's benefit plans for its directors, officers, employees or other
persons within the definition of "employee" for purposes of a registration of
shares for an employee benefit plan of the Company, related to the issuance
of Common Stock or rights under a dividend reinvestment and stock purchase plan,
or related to the issuance of Common Stock (or securities convertible or
exchangeable for Common Stock) as consideration in an acquisition transaction
that was entered into prior to the commencement of such Extension Period). Prior
to the termination of any such Extension Period, the Company may further defer
the payment of interest, provided that no Extension Period shall exceed the
period or periods specified in such Securities or extend beyond the Stated
Maturity of the principal of such Securities. Upon termination of any Extension
Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due on any Interest Payment Date, the Company may elect
to begin a new Extension Period, subject to the above requirements. No interest
shall be due and payable during an Extension Period, except at the end thereof.
The Company shall give the Holders of the Securities of such series and the

                                                                              33



Trustee written notice of its election to begin any such Extension Period at
least one Business Day prior to the next succeeding Interest Payment Date on
which interest on Securities of such series would be payable but for such
deferral or, with respect to the Securities of a series issued to a Trust, so
long as such Securities are held by such Trust, prior to the earlier of (i) the
next succeeding date on which Distributions on the Preferred Securities of such
Trust would be payable but for such deferral or (ii) the date the Administrative
Trustees of such Trust are required to give notice to any securities exchange or
other applicable self-regulatory organization or to holders of such Preferred
Securities of the record date or the date such Distributions are payable, but in
any event not less than one Business Day prior to such record date.

         The Trustee shall promptly give notice, in the name and at the expense
of the Company, of the Company's election to begin any such Extension Period to
the Holders of the Outstanding Securities of such series.

         SECTION 3.12.   Right of Set-Off.

         With respect to the Securities of a series issued to a Trust,
notwithstanding anything to the contrary in the Indenture, the Company shall
have the right to set-off any payment it is otherwise required to make
thereunder in respect of any such Security to the extent the Company has
theretofore made, or is concurrently on the date of such payment making, a
payment under the Guarantee relating to such Security or under Section 5.8 of
the Indenture.

         SECTION 3.13.   Agreed Tax Treatment.

         Each Security issued hereunder shall provide that the Company and, by
its acceptance of a Security or a beneficial interest therein, the Holder of,
and any Person that acquires a beneficial interest in, such Security intend that
such Security constitutes indebtedness and agree to treat such Security as
indebtedness for United States federal, local and state tax purposes.

         SECTION 3.14.   Shortening or Extension of Stated Maturity.

         If specified as contemplated by Section 2.1 or Section 3.1 with respect
to the Securities of a particular series, the Company shall have the right to
(i) shorten the Stated Maturity of the principal of the Securities of such
series at any time to any date not earlier than the first date on which the
Company has the right to redeem the Securities of such series, and (ii) extend
the Stated Maturity of the principal of the Securities of such series at any
time at its election for one or more periods, but in no event to a date later
than the 49th anniversary of the Original Issue Date of the Securities of such
series; provided that, if the Company elects to exercise its right to extend the
Stated Maturity of the principal of the Securities of such series pursuant to
clause (ii), above, at the time such election is made and at the time of
extension (A) the Company is not in bankruptcy, otherwise insolvent or in
liquidation, (B) the Company is not in default in the payment of any interest or
principal on such Securities, (C) in the case of any series of Securities held
by a Trust, such Trust is not in arrears on payments of Distributions on the
Preferred Securities issued by such Trust and no deferred Distributions are
accumulated, (D) such Securities are rated not less than BBB- by S&P or Baa3 by
Moody's or the equivalent by any other nationally recognized statistical rating
organization and (E) the Securities will not have a remaining period to maturity
of more than 30 years after such extension. In the event the

                                                                              34



Company elects to shorten or extend the Stated Maturity of any Securities, it
shall give written notice to the Trustee, and the Trustee shall give notice of
such shortening or extension to the Holders, no less than 30 and no more than
60 days prior to the effectiveness thereof.

         SECTION 3.15.   CUSIP Numbers.

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



                                   ARTICLE IV

                           SATISFACTION AND DISCHARGE

         SECTION 4.1.   Satisfaction and Discharge of Indenture.

effect (except as to any surviving rights of registration of transfer or
exchange of Securities herein expressly provided for and as otherwise provided
in this Section 4.1) and the Trustee, on demand of and at the expense of the
Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

         (1) either

         (A) all Securities theretofore authenticated and delivered (other than
(i) Securities which have been destroyed, lost or stolen and which have been
replaced or paid as provided in Section 3.6 and (ii) Securities for whose
payment money has theretofore been deposited in trust or segregated and held in
trust by the Company and thereafter repaid to the Company or discharged from
such trust, as provided in Section 10.3) have been delivered to the Trustee for
cancellation; or

         (B) all such Securities not theretofore delivered to the Trustee for
cancellation

                        (i)   have become due and payable, or
                
                       (ii)   will become due and payable at their Stated
                              Maturity within one year of the date of deposit,
                              or

                                                                              35



                           (iii) are to be called for redemption within one year
                  under arrangements satisfactory to the Trustee for the giving
                  of notice of redemption by the Trustee in the name, and at the
                  expense, of the Company,

                  and the Company, in the case of  Clause (B) (i), (ii) or (iii)
                  above, has deposited or caused to be deposited with the
                  Trustee as trust funds in trust for such purpose an amount in
                  the currency or currencies in which the Securities of such
                  series are payable sufficient to pay and discharge the entire
                  indebtedness on such Securities no theretofore delivered to
                  the Trustee for cancellation, including principal (and
                  premium, if any) and interest (including any Additional
                  Interest) to the date of such deposit (in the case of
                  Securities which have become due and payable) or to the Stated
                  Maturity or Redemption Date, as the case may be;

         (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

         (3) the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel each stating that all conditions precedent herein
provided for relating to the satisfaction and discharge of this Indenture have
been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 6.7, the obligations of
the Company to any Authenticating Agent under Section 6.14 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 4.2 and the last
paragraph of Section 10.3 shall survive.

         SECTION 4.2.   Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 10.3, all
money deposited with the Trustee pursuant to Section 4.1 shall be held in trust
and applied by the Trustee, in accordance with the provisions of the Securities
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for the payment of which such money or obligations have been
deposited with or received by the Trustee.

                                    REMEDIES

         SECTION 5.1.   Events of Default.

         "Event of Default", wherever used herein with respect to the Securities
of any series, means any one of the following events (whatever the reason for
such Event of Default and whether it shall be voluntary or involuntary or be
effected by operation of law or pursuant to


<PAGE>   43


                                                                              36



any judgment, decree or order of any court or any order, rule or regulation of
any administrative or governmental body):

         (1) default in the payment of any interest upon any Security of that
series, including any Additional Interest in respect thereof, when it becomes
due and payable, and continuance of such default for a period of 30 days
(subject to the deferral of any interest payment date in the case of an
Extension Period); or

         (2) default in the payment of the principal of (or premium, if any, on)
any Security of that series at its Maturity; or

         (3) default in the performance, or breach, in any material respect, of
any covenant or warranty of the Company in this Indenture with respect to that
series (other than a covenant or warranty a default in the performance of which
or the breach of which is elsewhere in this Section specifically dealt with),
and continuance of such default or breach for a period of 90 days after there
has been given, by registered or certified mail, to the Company by the Trustee
or to the Company and the Trustee by the Holders of at least 25% in principal
amount of the Outstanding Securities of that series a written notice specifying
such default or breach and requiring it to be remedied; or

         (4) the entry of a decree or order by a court having jurisdiction in
the premises adjudging the Company bankrupt or insolvent, or approving as
properly filed a petition seeking reorganization, arrangement, adjustment or
composition of or in respect of the Company under any applicable federal or
state bankruptcy, insolvency, reorganization or other similar law, or appointing
a receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or of any substantial part of its property or ordering
the winding up or liquidation of its affairs, and the continuance of any such
decree or order unstayed and in effect for a period of 60 consecutive days; or

         (5) the institution by the Company of proceedings to be adjudicated 
bankrupt or insolvent, or the consent by it to the institution of bankruptcy or
insolvency proceedings against it, or the filing by it of a petition or answer
or consent seeking reorganization or relief under any applicable federal or
state bankruptcy, insolvency, reorganization or other similar law, or the
consent by it to the filing of any such petition or to the appointment of a
receiver, liquidator, assignee, trustee, sequestrator (or other similar
official) of the Company or of any substantial part of its property, or the
making by it of an assignment for the benefit for creditors, or the admission by
it in writing of its inability to pay its debts generally as they become due and
its willingness to be adjudicated a bankrupt, or the taking of corporate action
by the Company in furtherance of any such action; or

         (6) any other Event of Default provided with respect to Securities of
that series.

         SECTION 5.2.   Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default (other than an Event of Default specified in
Section 5.1(4) or 5.1(5)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount


<PAGE>   44


                                                                              37



of the Outstanding Securities of that series may declare the principal amount
(or, if the Securities of that series are Discount Securities, such portion of
the principal amount as may be specified in the terms of that series) of all the
Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by Holders), provided that,
in the case of the Securities of a series issued to a Trust, if, upon an Event
of Default, the Trustee or the Holders of not less than 25% in principal amount
of the Outstanding Securities of that series fail to declare the principal
amount (or, if the Securities of that series are Discount Securities, such
portion of the principal amount as may be specified in the terms of that series)
of all the Securities of that series to be immediately due and payable, the
holders of at least 25% in aggregate liquidation amount of the corresponding
series of Preferred Securities then outstanding shall have such right by a
notice in writing to the Company and the Trustee; and upon any such declaration
such principal amount (or specified portion thereof) of and the accrued interest
(including any Additional Interest) on all the Securities of such series shall
become immediately due and payable. Payment of principal and interest (including
any Additional Interest) on such Securities shall remain subordinated to the
extent provided in Article XIII notwithstanding that such amount shall become
immediately due and payable as herein provided. If an Event of Default specified
in Section 5.1(4) or 5.1(5) with respect to Securities of any series at the time
Outstanding occurs, the principal amount of all the Securities of that series
(or, if the Securities of that series are Discount Securities, such portion of
the principal amount of such Securities as may be specified by the terms of that
series) shall automatically, and without any declaration or other action on the
part of the Trustee or any Holder, become immediately due and payable.

         At any time after such a declaration of acceleration with respect to
Securities of any series has been made and before a judgment or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article provided, the Holders of a majority in principal amount of the
Outstanding Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

         (1) the Company has paid or deposited with the Trustee a sum sufficient
to pay:

         (A) all overdue installments of interest (including any Additional
Interest) on all Securities of that series,

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

         (C) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel; and

         (2) all Events of Default with respect to Securities of that series,
other than the non-payment of the principal of Securities of that series which
has become due solely by such acceleration, have been cured or waived as
provided in Section 5.13;

provided that, in the case of Securities of a series held by a Trust, if the
Holders of at least a majority in principal amount of the Outstanding Securities
of that series fails to rescind and


<PAGE>   45


                                                                              38



annul such declaration and its consequences, the holders of a majority in
aggregate Liquidation Amount (as defined in the Trust Agreement under which such
Trust is formed) of the related series of Preferred Securities then outstanding
shall have such right by written notice to the Company and the Trustee, subject
to the satisfaction of the conditions set forth in Clauses (1) and (2) above of
this Section 5.2.

         No such rescission shall affect any subsequent default or impair any
right consequent thereon.

         SECTION 5.3. Collection of Indebtedness and Suits for Enforcement by
Trustee.

         The Company covenants that if:

         (1) default is made in the payment of any installment of interest
(including any Additional Interest) on any Security when such interest becomes
due and payable and such default continues for a period of 30 days, or

         (2) default is made in the payment of the principal of (and premium, if
any, on) any Security at the Maturity thereof, the Company will, upon demand of
the Trustee, pay to the Trustee, for the benefit of the Holders of such
Securities, the whole amount then due and payable on such Securities for
principal, including any sinking fund payment or analogous obligations (and
premium, if any) and interest (including any Additional Interest); and, in
addition thereto, all amounts owing the Trustee under Section 6.7.

         If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon the Securities and collect the
moneys adjudged or decreed to be payable in the manner provided by law out of
the property of the Company or any other obligor upon the Securities, wherever
situated.

         If an Event of Default with respect to Securities of any series occurs
and is continuing, the Trustee may in its discretion proceed to protect and
enforce its rights and the rights of the Holders of Securities of such series by
such appropriate judicial proceedings as the Trustee shall deem most effectual
to protect and enforce any such rights, whether for the specific enforcement of
any covenant or agreement in this Indenture or in aid of the exercise of any
power granted herein, or to enforce any other proper remedy.

         SECTION 5.4.   Trustee May File Proofs of Claim.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors,

         (a) the Trustee (irrespective of whether the principal of the
Securities of any series shall then be due and payable as therein expressed or
by declaration of acceleration or otherwise and irrespective of whether the
Trustee shall have made any demand on the Company for the payment of overdue
principal (and premium, if any) or interest (including any Additional Interest))
shall be entitled and empowered, by intervention in such proceeding or
otherwise,

         (i) to file and prove a claim for the whole amount of principal (or, if
the Securities of that series are Discount Securities, such portion of the
principal amount as may be due and payable pursuant to a declaration in
accordance with Section 5.2) (and premium, if any) and interest (including any
Additional Interest) owing and unpaid in respect to the Securities and to file
such other papers or documents as may be necessary or advisable and to take any
and all actions as are authorized under the Trust Indenture Act in order to have
the claims of the Holders and any predecessor to the Trustee under Section 6.7
allowed in any such judicial proceedings; and

         (ii) in particular, the Trustee shall be authorized to collect and
receive any moneys or other property payable or deliverable on any such claims
and to distribute the same in accordance with Section 5.6; and

         (b) 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 Trustee for
distribution in accordance with Section 5.6, and in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay to
the Trustee any amount due to it and any predecessor Trustee under Section 6.7.

         Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment or composition affecting the Securities
or the rights of any Holder thereof, or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors' or
other similar committee.

         SECTION 5.5. Trustee May Enforce Claims Without Possession of
Securities.

         All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of all the amounts owing the Trustee and any
predecessor Trustee under Section 6.7, its agents and counsel, be for the
ratable benefit of the Holders of the Securities in respect of which such
judgment has been recovered.

         SECTION 5.6.   Application of Money Collected.

         Any money or property collected or to be applied by the Trustee with
respect to a series of Securities pursuant to this Article shall be applied in
the following order, at the date or dates


<PAGE>   47


                                                                              40



fixed by the Trustee and, in case of the distribution of such money or property
on account of principal (or premium, if any) or interest (including any
Additional Interest), upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

         FIRST: To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 6.7;

         SECOND: Subject to Article XIII, to the payment of the amounts then due
and unpaid upon such series of Securities for principal (and premium, if any),
interest (including any Additional Interest) and Additional Taxes, in respect of
which or for the benefit of which such money has been collected, ratably,
without preference or priority of any kind, according to the amounts due and
payable on such series of Securities for principal (and premium, if any) and
interest (including any Additional Interest), respectively; and

         THIRD: The balance, if any, to the Person or Persons entitled thereto.

         SECTION 5.7.   Limitation on Suits.

         No Holder of any Securities of any series shall have any right to
institute any proceeding, judicial or otherwise, with respect to this Indenture
or for the appointment of a receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) or for any other remedy hereunder,
unless:

         (1) such Holder has previously given written notice to the Trustee of a
continuing Event of Default with respect to the Securities of that series;

         (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities of that series shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default in its own
name as Trustee hereunder;

         (3) such Holder or Holders have offered to the Trustee reasonable
security or indemnity against the costs, expenses and liabilities to be incurred
in compliance with such request;

         (4) the Trustee for 60 days after its receipt of such notice, request
and offer of security or indemnity has failed to institute any such proceeding;
and

         (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of that series;

it being understood and intended that no one or more of such Holders shall have
any right in any manner whatever by virtue of, or by availing itself of, any
provision of this Indenture to affect, disturb or prejudice the rights of any
other Holders of Securities, or to obtain or to seek to obtain priority or
preference over any other of such Holders or to enforce any right under this
Indenture, except in the manner herein provided and for the equal and ratable
benefit of all such Holders.


<PAGE>   48


                                                                              41




         SECTION 5.8. Unconditional Right of Holders to Receive Principal,
Premium and Interest; Direct Action by Holders of Preferred Securities.

         Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right which is absolute and unconditional to receive
payment of the principal of (and premium, if any) and (subject to Section 3.7)
interest (including any Additional Interest) on such Security on the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on
the Redemption Date) and to institute suit for the enforcement of any such
payment, and such right shall not be impaired without the consent of such
Holder. In the case of Securities of a series held by a Trust, any holder of the
corresponding series of Preferred Securities held by such Trust shall have the
right, upon the occurrence of an Event of Default described in Section 5.1(1) or
5.1(2), to institute a suit directly against the Company for enforcement of
payment to such holder of principal of (premium, if any) and (subject to Section
3.7) interest (including any Additional Interest) on the Securities having a
principal amount equal to the aggregate Liquidation Amount (as defined in the
Trust Agreement under which such Trust is formed) of such Preferred Securities
of the corresponding series held by such holder.

         SECTION 5.9.   Restoration of Rights and Remedies.

         If the Trustee, any Holder or any holder of Preferred Securities has
instituted any proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any reason, or has
been determined adversely to the Trustee, such Holder or such holder of
Preferred Securities, then and in every such case the Company, the Trustee, the
Holders and such holder of Preferred Securities shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of the
Trustee, the Holders and the holders of Preferred Securities shall continue as
though no such proceeding had been instituted.

         SECTION 5.10.   Rights and Remedies Cumulative.

         Except as otherwise provided in the last paragraph of Section 3.6, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

         SECTION 5.11.   Delay or Omission Not Waiver.

         No delay or omission of the Trustee, any Holder of any Security or any
holder of any Preferred Security to exercise any right or remedy accruing upon
any Event of Default shall impair any such right or remedy or constitute a
waiver of any such Event of Default or an acquiescence therein.

         Every right and remedy given by this Article or by law to the Trustee
or to the Holders and the right and remedy given to the holders of Preferred
Securities by Section 5.8 may be


<PAGE>   49


                                                                              42



exercised from time to time, and as often as may be deemed expedient, by the
Trustee, the Holders or the holders of Preferred Securities, as the case may be.

         SECTION 5.12.   Control by Holders.

         The Holders of a majority in principal amount of the Outstanding
Securities of any series shall have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Trustee or
exercising any trust or power conferred on the Trustee, with respect to the
Securities of such series, provided that:

         (1) such direction shall not be in conflict with any rule of law or
with this Indenture,

         (2) the Trustee may take any other action deemed proper by the Trustee
which is not inconsistent with such direction, and

         (3) subject to the provisions of Section 6.1, the Trustee shall have
the right to decline to follow such direction if a Responsible Officer or
Officers of the Trustee shall, in good faith, determine that the proceeding so
directed would be unjustly prejudicial to the Holders not joining in any such
direction or would involve the Trustee in personal liability.

         SECTION 5.13.   Waiver of Past Defaults.

         The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series and, in the case of any Securities of a
series issued to a Trust, the holders of a majority in Liquidation Amount (as
defined in the relevant Trust Agreement) of Preferred Securities issued by such
Trust may waive any past default hereunder and its consequences with respect to
such series except a default:

         (1) in the payment of the principal of (or premium, if any) or interest
(including any Additional Interest) on any Security of such series (unless all
Events of Default with respect to Securities of that series, other than the
non-payment of the principal of Securities of that series which has become due
solely by acceleration, have been cured or annulled as provided in Section
5.3 and the Company has paid or deposited with the Trustee a sum sufficient to
pay all overdue installments of interest (including any Additional Interest) on
all Securities of that series, the principal of (and premium, if any, on) any
Securities of that series which have become due otherwise than by such
declaration of acceleration and interest thereon at the rate borne by the
Securities, and all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel), or

         (2) in respect of a covenant or provision hereof which under Article IX
cannot be modified or amended without the consent of the Holder of each
Outstanding Security of such series affected.

         Any such waiver shall be deemed to be on behalf of the Holders of all
the Securities of such series or, in the case of a waiver by holders of
Preferred Securities issued by such Trust, by all holders of Preferred
Securities issued by such Trust.



<PAGE>   50


                                                                              43



         Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair any right consequent thereon.

         SECTION 5.14.   Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Holder, or group of Holders, holding in
the aggregate more than 10% in principal amount of the Outstanding Securities of
any series, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of (or premium, if any) or interest (including any
Additional Interest) on any Security on or after the respective Stated
Maturities expressed in such Security.

         SECTION 5.15.   Waiver of Usury, Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any usury, stay or extension law wherever
enacted, now or at any time hereafter in force, which may affect the covenants
or the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.


                                   ARTICLE VI

                                   THE TRUSTEE

         SECTION 6.1.   Certain Duties and Responsibilities.

         (a) Except during the continuance of an Event of Default,

         (1) the Trustee undertakes to perform such duties and only such duties
as are specifically set forth in this Indenture, and no implied covenants or
obligations shall be read into this Indenture against the Trustee; and

         (2) in the absence of bad faith on its part, the Trustee may
conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the
Trustee and conforming to the requirements of this Indenture; but


<PAGE>   51


                                                                              44



in the case of any such certificates or opinions which by any provisions hereof
are specifically required to be furnished to the Trustee, the Trustee shall be
under a duty to examine the same to determine whether or not they conform to the
requirements of this Indenture.

         (b) In case an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his own affairs.

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

         (1) this Subsection shall not be construed to limit the effect of
Subsection (a) of this Section;

         (2) the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer, unless it shall be proved that the Trustee
was negligent in ascertaining the pertinent facts; and

         (3) the 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
Holders pursuant to Section 5.12 relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred upon the Trustee, under this Indenture with respect
to the Securities of such series.

         (d) No provision of this Indenture shall require the Trustee to expend
or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder, or in the exercise of any of its
rights or powers, if there shall be reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

         (e) Whether or not therein expressly so provided, every provision of
this Indenture relating to the conduct or affecting the liability of or
affording protection to the Trustee shall be subject to the provisions of this
Section.

         SECTION 6.2.   Notice of Defaults.

         Within 90 days after actual knowledge by a Responsible Officer of the
Trustee of the occurrence of any default hereunder with respect to the
Securities of any series, the Trustee shall transmit by mail to all Holders of
Securities of such series, as their names and addresses appear in the Securities
Register, notice of such default, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment
of the principal of (or premium, if any) or interest (including any Additional
Interest) on any Security of such series, the Trustee shall be protected in
withholding such notice if and so long as the board of directors, the executive
committee or a trust committee of directors and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the
interests of


<PAGE>   52


                                                                              45



the Holders of Securities of such series; and provided, further, that, in the
case of any default of the character specified in Section 5.1(3), no such notice
to Holders of Securities of such series shall be given until at least 30 days
after the occurrence thereof. For the purpose of this Section, the term
"default" means any event which is, or after notice or lapse of time or both
would become, an Event of Default with respect to Securities of such series.

         SECTION 6.3.   Certain Rights of Trustee.

         Subject to the provisions of Section 6.1:

         (a) the Trustee may rely and shall be protected in acting or refraining
from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order, bond, debenture, Security 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) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution;

         (c) whenever in the administration of this Indenture the Trustee shall
deem it desirable that a matter be proved or established prior to taking,
suffering or omitting any action hereunder, the Trustee (unless other evidence
be herein specifically prescribed) may, in the absence of bad faith on its part,
rely upon an Officers' Certificate;

         (d) the Trustee may consult with counsel of its selection and the
advice of such counsel or any Opinion of 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;

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

         (f) the 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, direction, consent, order, bond, indenture,
Security or other paper or document, but the Trustee in its discretion may make
such inquiry or investigation into such facts or matters as it may see fit, and,
if the Trustee shall determine to make such inquiry or investigation, it shall
be entitled to examine the books, records and premises of the Company,
personally or by agent or attorney;

         (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys and the Trustee shall not be responsible for any misconduct or
negligence on the part of any agent or attorney appointed with due care by it
hereunder; and



<PAGE>   53


                                                                              46



         (h) the Trustee shall not be liable for any action taken, suffered, or
omitted to be taken by it in good faith and reasonably believed by it to be
authorized or within the discretion or rights or powers conferred upon it by
this Indenture.

         SECTION 6.4.   Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and neither the Trustee nor any Authenticating Agent assumes any
responsibility for their correctness. The Trustee makes no representations as to
the validity or sufficiency of this Indenture or of the Securities. Neither the
Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of the Securities or the proceeds thereof.

         SECTION 6.5.   May Hold Securities.

         The Trustee, any Authenticating Agent, any Paying Agent, any Securities
Registrar or any other agent of the Company, in its individual or any other
capacity, may become the owner or pledgee of Securities and, subject to Sections
6.8 and 6.13, may otherwise deal with the Company with the same rights it would
have if it were not Trustee, Authenticating Agent, Paying Agent, Securities
Registrar or such other agent.

         SECTION 6.6.   Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed in writing with the Company.

         SECTION 6.7.   Compensation and Reimbursement.

         The Company, as borrower, agrees

         (1) to pay to the Trustee from time to time such compensation as shall
be agreed in writing between the Company and the Trustee for all services
rendered by it hereunder (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust);

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

         (3) to indemnify each of the Trustee and any predecessor Trustee for,
and to hold it harmless against, any and all loss, liability, damage, claim or
expense (including the reasonable compensation and the expenses and
disbursements of its agents and counsel) incurred without negligence or bad
faith, arising out of or in connection with the acceptance or administration of
this trust or the performance of its duties hereunder, including the costs and
expenses of


<PAGE>   54


                                                                              47



defending itself against any claim or liability in connection with the exercise
or performance of any of its powers or duties hereunder. This indemnification
shall survive the termination of this Agreement.

         To secure the Company's payment obligations in this Section, the
Company and the Holders agree that the Trustee shall have a lien prior to the
Securities on all money or property held or collected by the Trustee. Such lien
shall survive the satisfaction and discharge of this Indenture.

         When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 5.1(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under the Bankruptcy Reform Act of 1978 or any successor statute.

         SECTION 6.8.   Disqualification; Conflicting Interests.

         The Trustee for the Securities of any series issued hereunder shall be
subject to the provisions of Section 310(b) of the Trust Indenture Act. Nothing
herein shall prevent the Trustee from filing with the Commission the application
referred to in the second to last paragraph of said Section 310(b).

         SECTION 6.9.   Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall be

         (a) a corporation organized and doing business under the laws of the
United States of America or of any state or territory or the District of
Columbia, authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by federal, state, territorial or District
of Columbia authority, or

         (b) a corporation or other Person organized and doing business under
the laws of a foreign government that is permitted to act as Trustee pursuant to
a rule, regulation or order of the Commission, authorized under such laws to
exercise corporate trust powers, and subject to supervision or examination by
authority of such foreign government or a political subdivision thereof
substantially equivalent to supervision or examination applicable to United
States institutional trustees,

in either case having a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by federal or state authority. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of the aforesaid supervising or examining authority, then,
for the purposes of this Section, the combined capital and surplus of such
corporation 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 Trustee
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. Neither the Company nor any Person directly or indirectly
controlling, controlled by or under common control with the Company shall serve

         SECTION 6.10.   Resignation and Removal; Appointment of Successor.

         (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 6.11.

         (b) The Trustee may resign at any time with respect to the Securities
of one or more series by giving written notice thereof to the Company. If an
instrument of acceptance by a successor Trustee shall not have been delivered to
the Trustee within 30 days after the giving of such notice of resignation, the
resigning Trustee may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         (c) The Trustee may be removed at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series, delivered to the Trustee and to
the Company. If an instrument of acceptance by a successor Trustee shall not
have been delivered to the Trustee within 30 days after such removal, the
Trustee being removed may petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such
series.

         (d)   If at any time:

         (1) the Trustee shall fail to comply with Section 6.8 after written
request therefor by the Company or by any Holder who has been a bona fide Holder
of a Security for at least six months, or

         (2) the Trustee shall cease to be eligible under Section 6.9 and shall
fail to resign after written request therefor by the Company or by any such
Holder, or

         (3) the Trustee shall become incapable of acting or shall be adjudged a
bankrupt or insolvent or a receiver of the Trustee or of its property shall be
appointed or any public officer shall take charge or control of the Trustee or
of its property or affairs for the purpose of rehabilitation, conservation or
liquidation,

then, in any such case, (i) the Company, acting pursuant to the authority of a
Board Resolution, may remove the Trustee with respect to all Securities, or (ii)
subject to Section 5.14, any Holder who has been a bona fide Holder of a
Security for at least six months may, on behalf of himself and all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee with respect to all Securities and the appointment of a successor
Trustee or Trustees.


         (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Company, by a Board
Resolution, shall promptly appoint a successor Trustee with respect to the
Securities of that or those series. If, within one year after such resignation,
removal or incapability, or the occurrence of such vacancy, a successor Trustee
with respect to the Securities of any series shall be appointed by Act of the
Holders of a majority in principal

                                                                              49



amount of the Outstanding Securities of such series delivered to the Company and
the retiring Trustee, the successor Trustee so appointed shall, forthwith upon
its acceptance of such appointment, become the successor Trustee with respect to
the Securities of such series and supersede the successor Trustee appointed by
the Company. If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders and accepted
appointment in the manner hereinafter provided, any Holder who has been a bona
fide Holder of a Security for at least six months may, subject to Section 5.14,
on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect
to the Securities of such series.

         (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Securities of such series as their names and addresses appear in the
Securities Register. Each notice shall include the name of the successor Trustee
with respect to the Securities of such series and the address of its Corporate
Trust Office.

         SECTION 6.11.   Acceptance of Appointment by Successor.

         (a) In case of the appointment hereunder of a successor Trustee with
respect to all Securities, every such successor Trustee so appointed shall
execute, acknowledge and deliver to the Company 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 Company 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
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.

         (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto
wherein each successor Trustee shall accept such appointment and which (1) shall
contain such provisions as shall be necessary or desirable to transfer and
confirm to, and to vest in, each successor Trustee all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series to which the appointment of such successor Trustee relates, (2)
if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Securities of that or those series as to which the retiring
Trustee is not retiring shall continue to be vested in the retiring Trustee, and
(3) shall add to or change any of the provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts
hereunder by more than one Trustee, it being understood that nothing herein or
in such supplemental indenture shall constitute such Trustees co-trustees of the
same trust and that each such Trustee shall be trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee; and upon the execution and delivery of such supplemental
indenture


<PAGE>   57


                                                                              50



the resignation or removal of the retiring Trustee shall become effective to the
extent provided therein and each 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 with respect to the Securities of
that or those series to which the appointment of such successor Trustee relates;
but, on request of the Company or any successor Trustee, such retiring Trustee
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder with respect to the Securities
of that or those series to which the appointment of such successor Trustee
relates.

         (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to
in paragraph (a) or (b) of this Section, as the case may be.

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

         SECTION 6.12. Merger, Conversion, Consolidation or Succession to
Business.

         Any corporation into which the 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 the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto. In case any Securities shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated, and in case any
Securities shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor Trustee or in
the name of such successor Trustee, and in all cases the certificate of
authentication shall have the full force which it is provided anywhere in the
Securities or in this Indenture that the certificate of the Trustee shall have.

         SECTION 6.13.   Preferential Collection of Claims Against Company.

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

         SECTION 6.14.   Appointment of Authenticating Agent.

         The Trustee may appoint an Authenticating Agent or Agents with respect
to one or more series of Securities which shall be authorized to act on behalf
of the Trustee to authenticate Securities of such series issued upon original
issue and upon exchange, registration of transfer or partial redemption thereof
or pursuant to Section 3.6, and Securities so authenticated shall be entitled to
the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of


<PAGE>   58


                                                                              51



authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a corporation organized and doing business under the laws of the United
States of America, or of any state or territory or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 and subject to supervision or
examination by federal or state authority. If such Authenticating Agent
publishes reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section the combined capital and surplus of such Authenticating Agent
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 an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

         Any corporation into which an Authenticating Agent 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 Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of an Authenticating Agent shall be the successor
Authenticating Agent hereunder, provided such corporation shall be otherwise
eligible under this Section, without the execution or filing of any paper or any
further act on the part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall give notice of such
appointment in the manner provided in Section 1.6 to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provision of this Section.

         The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation for its services under this Section.

         If an appointment with respect to one or more series is made pursuant
to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee's certificate of authentication, an alternative
certificate of authentication in the following form:

         This is one of the Securities referred to in the within mentioned
Indenture.

         (a) The Trustee shall transmit to Holders such reports concerning the
Trustee and its actions under this Indenture as may be required pursuant to the
Trust Indenture Act at the times and in the manner provided pursuant thereto. If
required by Section 313(a) of the Trust Indenture Act, the Trustee shall, within
sixty days after each May 15 following the date of this Indenture deliver to
Holders a brief report, dated as of such May 15, which complies with the

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

Person, or any conveyance, transfer or lease by the Company of its properties
and assets substantially as an entirety to any Person in accordance with Section
8.1, the successor Person formed by such consolidation or into which the Company
is merged or to which such conveyance, transfer or lease is made shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under this Indenture with the same effect as if such successor Person
had been named as the Company herein; and in the event of any such conveyance,
transfer or lease the Company shall be discharged from all obligations and
covenants under the Indenture and the Securities and may be dissolved and
liquidated.

Person instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall make available for delivery any Securities which previously shall have
been signed and delivered by the officers of the Company to the Trustee for
authentication pursuant to such provisions and any Securities which such
successor Person thereafter shall cause to be signed and delivered to

the Trustee on its behalf for the purpose pursuant to such provisions. All the
Securities so issued shall in all respects have the same legal rank and benefit
under this Indenture as the Securities theretofore or thereafter issued in
accordance with the terms of this Indenture as though all of such Securities had
been issued at the date of the execution hereof.

         In case of any such consolidation, merger, sale, conveyance or lease,
such changes in phraseology and form may be made in the Securities thereafter to
be issued as may be appropriate.

other provisions of this Indenture cannot be modified or waived without the
consent of the Holder of each Security affected thereby; or

                                                                              57



         (4) modify the provisions in Article XIII of this Indenture with
respect to the subordination of Outstanding Securities of any series in a manner
adverse to the Holders thereof; provided, further, that, in the case of the
Securities of a series issued to a Trust, so long as any of the corresponding
series of Preferred Securities issued by such Trust remains outstanding, (i) no
such amendment shall be made that adversely affects the holders of such
Preferred Securities in any material respect, and no termination of this
Indenture shall occur, and no waiver of any Event of Default or compliance with
any covenant under this Indenture shall be effective, without the prior consent
of the holders of at least a majority of the aggregate Liquidation Amount (as
defined in the Trust Agreement under which such Trust is organized) of such
Preferred Securities then outstanding unless and until the principal (and
premium, if any) of the Securities of such series and all accrued and, subject
to Section 3.7, unpaid interest (including any Additional Interest) thereon have
been paid in full and (ii) no amendment shall be made to Section 5.8 of this
Indenture that would impair the rights of the holders of Preferred Securities
provided therein without the prior consent of the holders of each Preferred
Security then outstanding unless and until the principal (and premium, if any)
of the Securities of such series and all accrued and (subject to Section 3.7)
unpaid interest (including any Additional Interest) thereon have been paid in
full.

         A supplemental indenture that changes or eliminates any covenant or
other provision of this Indenture that has expressly been included solely for
the benefit of one or more particular series of Securities or Preferred
Securities, or which modifies the rights of the Holders of Securities or holders
of Preferred Securities of such series with respect to such covenant or other
provision, shall be deemed not to affect the rights under this Indenture of the
Holders of Securities or holders of Preferred Securities of any other series.

         It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

         SECTION 9.3.   Execution of Supplemental Indentures.

         In executing or accepting the additional trusts created by any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and (subject to Section 6.1) shall be fully protected in relying upon, an
Officers' Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture, and
that all conditions precedent have been complied with. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

         SECTION 9.4.   Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,
this Indenture shall be modified in accordance therewith, and such supplemental
indenture shall form a part of this Indenture for all purposes; and every Holder
of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby.

         SECTION 9.5.   Conformity with Trust Indenture Act.

         Every supplemental indenture executed pursuant to this Article shall
conform to the requirements of the Trust Indenture Act as then in effect.

         SECTION 9.6.   Reference in Securities to Supplemental Indentures.

         Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Company, bear a notation in form approved by the Company as to any matter
provided for in such supplemental indenture. If the Company shall so determine,
new Securities of any series so modified as to conform, in the opinion of the
Company, to any such supplemental indenture may be prepared and executed by the
Company and authenticated and delivered by the Trustee in exchange for
Outstanding Securities of such series.


                                    ARTICLE X

                                    COVENANTS

         SECTION 10.1.  Payment of Principal, Premium and Interest.

         The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay the principal of (and premium,
if any) and interest (including Additional Interest) on the Securities of that
series in accordance with the terms of such Securities and this Indenture.

         SECTION 10.2.  Maintenance of Office or Agency.

         The Company will maintain in each Place of Payment for any series of
Securities, an office or agency where Securities of that series may be presented
or surrendered for payment and an office or agency where Securities of that
series may be surrendered for transfer or exchange and where notices and demands
to or upon the Company in respect of the Securities of that series and this
Indenture may be served. The Company initially appoints the Trustee, acting
through its Corporate Trust Office, as its agent for said purposes. The Company
will give prompt written notice to the Trustee of any change in the location of
any such office or agency. If at any time the Company shall fail to maintain
such office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the Corporate Trust Office of the Trustee, and the Company hereby


<PAGE>   66


                                                                              59



appoints the Trustee as its agent to receive all such presentations, surrenders,
notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all of such purposes, and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in each
Place of Payment for Securities of any series for such purposes. The Company
will give prompt written notice to the Trustee of any such designation and any
change in the location of any such office or agency.

         SECTION 10.3.   Money for Security Payments to be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any of the Securities of such
series, segregate and hold in trust for the benefit of the Persons entitled
thereto a sum sufficient to pay the principal (and premium, if any) or interest
so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided, and will promptly notify the Trustee of its
failure so to act.

         Whenever the Company shall have one or more Paying Agents, it will,
prior to 10:00 a.m. New York City time on each due date of the principal of or
interest on any Securities, deposit with a Paying Agent a sum sufficient to pay
the principal (and premium, if any) or interest so becoming due, such sum to be
held in trust for the benefit of the Persons entitled to such principal and
premium (if any) or interest, and (unless such Paying Agent is the Trustee) the
Company will promptly notify the Trustee of its failure so to act.

         The Company will cause each Paying Agent other than the Trustee to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

         (1) hold all sums held by it for the payment of the principal of (and
premium, if any) or interest (including Additional Interest) on Securities in
trust for the benefit of the Persons entitled thereto until such sums shall be
paid to such Persons or otherwise disposed of as herein provided;

         (2) give the Trustee notice of any default by the Company (or any other
obligor upon the Securities) in the making of any payment of principal (and
premium, if any) or interest (including Additional Interest);

         (3) at any time during the continuance of any such default, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in
trust by such Paying Agent; and

         (4) comply with the provisions of the Trust Indenture Act applicable to
it as a Paying Agent.



<PAGE>   67


                                                                              60



         The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by the Company or any Paying Agent to
the Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

         Any money deposited with the Trustee or any Paying Agent, or then held
by the Company, in trust for the payment of the principal of (and premium, if
any) or interest (including Additional Interest) on any Security and remaining
unclaimed for two years after such principal (and premium, if any) or interest
has become due and payable shall (unless otherwise required by mandatory
provision of applicable escheat or abandoned or unclaimed property law) be paid
on Company Request to the Company, or (if then held by the Company) shall
(unless otherwise required by mandatory provision of applicable escheat or
abandoned or unclaimed property law) be discharged from such trust; and the
Holder of such Security shall thereafter, as an unsecured general creditor, look
only to the Company for payment thereof, and all liability of the Trustee or
such Paying Agent with respect to such trust money, and all liability of the
Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment,
may at the expense of the Company cause to be published once, in a newspaper
published in the English language, customarily published on each Business Day
and of general circulation in the Borough of Manhattan, The City of New York,
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Company.

         SECTION 10.4.   Statement as to Compliance.

         The Company shall deliver to the Trustee, within 120 days after the end
of each calendar year of the Company ending after the date hereof, an Officers'
Certificate, one of the signatories of which shall be the principal executive,
principal financial or principal accounting officer of the Company, covering the
preceding calendar year, stating whether or not to the best knowledge of the
signers thereof the Company is in default in the performance, observance or
fulfillment of or compliance with any of the terms, provisions, covenants and
conditions of this Indenture, and if the Company shall be in default, specifying
all such defaults and the nature and status thereof of which they may have
knowledge. For the purpose of this Section 10.4, compliance shall be determined
without regard to any grace period or requirement of notice provided pursuant to
the terms of this Indenture.

         SECTION 10.5.   Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
covenant or condition provided pursuant to Section 3.1, 9.1(3) or 9.1(4) with
respect to the Securities of any series, if before or after the time for such
compliance the Holders of at least a majority in principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either
waive such compliance in such instance or generally waive compliance with such
covenant or condition, but no such waiver shall extend to or affect such
covenant or condition except to


<PAGE>   68


                                                                              61



the extent so expressly waived, and, until such waiver shall become effective,
the obligations of the Company in respect of any such covenant or condition
shall remain in full force and effect.

         SECTION 10.6.   Additional Sums.

         In the case of the Securities of a series initially issued to a Trust,
so long as no Event of Default has occurred and is continuing and except as
otherwise specified as contemplated by Section 2.1 or Section 3.1, if (i) a
Trust is the Holder of all of the Outstanding Securities of such series, and
(ii) a Tax Event has occurred and is continuing in respect of such Securities,
the Company shall pay to such Trust (or its permitted successor under the
related Trust Agreement) for so long as such Trust (or its permitted successor)
is the registered holder of the Outstanding Securities of such series, together
with any payment of principal of (or premium, if any) or interest (including any
Additional Interest) on such Securities, such additional sums as may be
necessary in order that the amount of Distributions (including any Additional
Amounts (as defined in such Trust Agreement)) then payable by such Trust in
respect of the related Preferred Securities and Common Securities in accordance
with the terms thereof shall not be reduced as a result of any Additional Taxes
arising from such Tax Event (the "Additional Sums"). Whenever in this Indenture
or the Securities there is a reference in any context to the payment of
principal of (or premium, if any) or interest (including Additional Interest) on
the Securities, such mention shall be deemed to include mention of the payments
of the Additional Sums provided for in this paragraph to the extent that, in
such context, Additional Sums are, were or would be payable in respect thereof
pursuant to the provisions of this paragraph, and any express mention of the
payment of Additional Sums (if applicable) in any provision hereof shall not be
construed as excluding Additional Sums in those provisions hereof where such
express mention is not made; provided, however, that the deferral of the payment
of interest pursuant to Section 3.11 or the terms of the Securities shall not
defer the payment of any Additional Sums that may be due and payable.

         SECTION 10.7.   Additional Covenants.

         The Company covenants and agrees with each Holder of Securities of each
series that it shall not, and it shall not permit any Subsidiary of the Company
to, (i) declare or pay any dividends or distributions on, or redeem, purchase,
acquire or make a liquidation payment with respect to, any shares of the
Company's capital stock, or (ii) make any payment of principal of or interest or
premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank pari passu with or junior in interest to the Securities of
such series or (iii) make any guarantee payments with respect to any guarantee
by the Company of debt securities of any subsidiary of the Company if such
guarantee ranks pari passu with or junior in interest to the Securities (other
than (a) dividends or distributions in the Company's capital stock, (b) any
declaration of a dividend in connection with the implementation of a Rights Plan
or the redemption or repurchase of any rights distributed pursuant to a Rights
Plan, (c) payments under the Guarantee with respect to the Preferred Securities
relating to Securities of such Series, and (d) purchases of Common Stock related
to the issuance of Common Stock or rights or options under any of the Company's
benefit plans for its directors, officers, employees or other persons within the
definition of "employee" for purposes of a registration of shares for an
employee benefit plan of the Company, related to the issuance of Common
Stock or rights


<PAGE>   69


                                                                              62



under a dividend reinvestment and stock purchase plan, or related to the
issuance of Common Stock (or securities convertible or exchangeable for Common
Stock) as consideration in an acquisition transaction) if at such time (x) there
shall have occurred any event of which the Company has actual knowledge that (A)
with the giving of notice or the lapse of time or both, would constitute an
Event of Default with respect to the Securities of such series and (B) in
respect of which the Company shall not have taken reasonable steps to cure, (y)
if the Securities of such series are held by a Trust, the Company shall be in
default with respect to its payment of any obligations under the Guarantee
relating to the Preferred Securities issued by such Trust or (z) the Company
shall have given notice of its election to begin an Extension Period with
respect to the Securities of such series as provided herein and shall not have
rescinded such notice, or such Extension Period, or any extension thereof, shall
be continuing.

         The Company also covenants with each Holder of Securities of a series
issued to a Trust (i) to maintain directly or indirectly 100% ownership of the
Common Securities of such Trust; provided, however, that any permitted successor
of the Company hereunder may succeed to the Company's ownership of such Common
Securities, (ii) not to voluntarily terminate, wind-up or liquidate such Trust,
except (a) in connection with a distribution of the Securities of such series to
the holders of the Trust Securities of such Trust in liquidation of such Trust
or (b) in connection with certain mergers, consolidations or amalgamations
permitted by the related Trust Agreement and (iii) to use its reasonable
efforts, consistent with the terms and provisions of such Trust Agreement, to
cause such Trust to remain classified as a grantor trust and not be
taxable as a corporation for United States federal income tax purposes.

         SECTION 10.8.   Calculation of Original Issue Discount.

         The Company shall file with the Trustee promptly at the end of each
calendar year a written notice specifying the amount of original issue discount
(including daily rates and accrual periods) accrued on Outstanding Securities as
of the end of such year, if any.


                                   ARTICLE XI

                            REDEMPTION OF SECURITIES

         SECTION 11.1.   Applicability of This Article.

         Redemption of Securities of any series (whether by operation of a
sinking fund or otherwise) as permitted or required by any form of Security
issued pursuant to this Indenture shall be made in accordance with such form of
Security and this Article; provided, however, that if any provision of any such
form of Security shall conflict with any provision of this Article, the
provision of such form of Security shall govern. Except as otherwise set forth
in the form of Security for such series, each Security of such series shall be
subject to partial redemption only in the amount of $25 or, in the case of the
Securities of a series issued to a Trust, $25, or integral multiples thereof.

         SECTION 11.2.   Election to Redeem; Notice to Trustee.



<PAGE>   70


                                                                              63



         The election of the Company to redeem any Securities shall be evidenced
by or pursuant to a Board Resolution. In case of any redemption at the election
of the Company of the Securities, the Company shall, not less than 45 nor more
than 60 days prior to the Redemption Date (unless a shorter notice shall be
satisfactory to the Trustee), notify the Trustee of such date and of the
principal amount of Securities of that series to be redeemed. In the case of any
redemption of Securities prior to the expiration of any restriction on such
redemption provided in the terms of such Securities, the Company shall furnish
the Trustee with an Officers' Certificate and an Opinion of Counsel evidencing
compliance with such restriction.

         SECTION 11.3.   Selection of Securities to be Redeemed.

         If less than all the Securities of any series are to be redeemed
(unless all the Securities of specified tenor are to be redeemed or unless such
redemption affects only a single Security), the particular Securities to be
redeemed shall be selected not more than 60 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of such series not previously
called for redemption, by lot or such other method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a
portion of the principal amount of any Security of such series, provided that
the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized
denomination) for such Security. If less than all the Securities of such series
and of a specified tenor are to be redeemed (unless such redemption affects only
a single Security), the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series and specified tenor not previously called
for redemption in accordance with the preceding sentence.

        The Trustee shall promptly notify the Company in writing of the
Securities selected for partial redemption and the principal amount thereof to
be redeemed. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed. If the Company shall so direct, Securities registered in the name of
the Company, any Affiliate or any Subsidiary thereof shall not be included in
the Securities selected for redemption.

         SECTION 11.4.   Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not later than the thirtieth day, and not earlier than the
sixtieth day, prior to the Redemption Date, to each Holder of Securities to be
redeemed, at the address of such Holder as it appears in the Securities
Register.

         With respect to Securities of each series to be redeemed, each notice
of redemption shall identify the Securities to be redeemed (including CUSIP
number, if a CUSIP number has been assigned to such Securities of such Series)
and shall state:

         (a) the Redemption Date;

         (b) the Redemption Price;


<PAGE>   71


                                                                              64




         (c) if less than all Outstanding Securities of such particular series
and having the same terms are to be redeemed, the identification (and, in the
case of partial redemption, the respective principal amounts) of the particular
Securities to be redeemed;

         (d) that on the Redemption Date, the Redemption Price will become due
and payable upon each such Security or portion thereof, and that interest
thereon, if any, shall cease to accrue on and after said date;

         (e) the place or places where such Securities are to be surrendered for
payment of the Redemption Price; and

         (f) that the redemption is for a sinking fund, if such is the case.

         Notice of redemption of Securities to be redeemed at the election of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall not be
irrevocable. The notice if mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder
receives such notice. In any case, a failure to give such notice by mail or any
defect in the notice to the Holder of any Security designated for redemption as
a whole or in part shall not affect the validity of the proceedings for the
redemption of any other Security.

         SECTION 11.5.   Deposit of Redemption Price.

         Prior to 10:00 a.m. New York City time on the Redemption Date specified
in the notice of redemption given as provided in Section 11.4, the Company will
deposit with the Trustee or with one or more Paying Agents (or if the Company is
acting as its own Paying Agent, the Company will segregate and hold in trust as
provided in Section 10.3) an amount of money sufficient to pay the Redemption
Price of, and any accrued interest (including Additional Interest) on, all the
Securities which are to be redeemed on that date.

         SECTION 11.6.   Payment of Securities Called for Redemption.

         If any notice of redemption has been given as provided in Section 11.4,
the Securities or portion of Securities with respect to which such notice has
been given shall become due and payable on the date and at the place or places
stated in such notice at the applicable Redemption Price. On presentation and
surrender of such Securities at a Place of Payment in said notice specified, the
said securities or the specified portions thereof shall be paid and redeemed by
the Company at the applicable Redemption Price, together with accrued interest
(including any Additional Interest) to the Redemption Date; provided, however,
that, unless otherwise specified as contemplated by Section 3.1, installments of
interest whose Stated Maturity is on or prior to the Redemption Date will be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 3.7.

         Upon presentation of any Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and make available for delivery
to the Holder thereof, at the expense of the Company, a new Security or
Securities of the same series, of authorized


<PAGE>   72


                                                                              65



denominations, in aggregate principal amount equal to the unredeemed portion of
the Security so presented and having the same Original Issue Date, Stated
Maturity and terms. If a Global Security is so surrendered, such new Security
will also be a new Global Security.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal of and premium, if any, on such
Security shall, until paid, bear interest from the Redemption Date at the rate
prescribed therefor in the Security.

         SECTION 11.7.   Right of Redemption of Securities.

         Except as otherwise established pursuant to Section 3.1 for the
Securities of a series, the Company, at its option, may redeem (A) the
Securities of any series, in whole (but not in part), upon the occurrence and
during the continuation of a Tax Event, at any time within 90 days of the
occurrence of such Tax Event, or (B) the Securities of a series initially issued
to a Trust, (i) on or after the date five years after the Original Issue Date of
such Securities, in whole at any time or in part from time to time, or (ii) upon
the occurrence and during the continuation of a Capital Treatment Event, at any
time within 90 days following the occurrence of such Capital Treatment Event in
respect of such Trust, in whole (but not in part), in each case at a Redemption
Price equal to 100% of the principal amount thereof.


                                   ARTICLE XII

                                  SINKING FUNDS

         SECTION 12.1.   Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities.

         The minimum amount of any sinking fund payment provided for by the
terms of any Securities of any series is herein referred to as a "mandatory
sinking fund payment", and any sinking fund payment in excess of such minimum
amount which is permitted to be made by the terms of such Securities of any
series is herein referred to as an "optional sinking fund payment". If provided
for by the terms of any Securities of any series, the cash amount of any sinking
fund payment may be subject to reduction as provided in Section 12.2. Each
sinking fund payment shall be applied to the redemption of Securities of any
series as provided for by the terms of such Securities.

                                                                              66



         SECTION 12.2.   Satisfaction of Sinking Fund Payments with Securities.

         In lieu of making all or any part of a mandatory sinking fund payment
with respect to any Securities of a series in cash, the Company may at its
option, at any time no more than 16 months and no less than 30 days prior to the
date on which such sinking fund payment is due, deliver to the Trustee
Securities of such series (together with the unmatured coupons, if any,
appertaining thereto) theretofore purchased or otherwise acquired by the
Company, except Securities of such series that have been redeemed through the
application of mandatory or optional sinking fund payments pursuant to the terms
of the Securities of such series, accompanied by a Company Order instructing the
Trustee to credit such obligations and stating that the Securities of such
series were originally issued by the Company by way of bona fide sale or other
negotiation for value; provided that the Securities to be so credited have not
been previously so credited. The Securities to be so credited shall be received
and credited for such purpose by the Trustee at the redemption price for such
Securities, as specified in the Securities so to be redeemed, for redemption
through operation of the sinking fund and the amount of such sinking fund
payment shall be reduced accordingly.

         SECTION 12.3.   Redemption of Securities for Sinking Fund.

         Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
such Securities pursuant to the terms of such Securities, the portion thereof,
if any, which is to be satisfied by payment of cash in the currency in which the
Securities of such series are payable (except as provided pursuant to Section
3.1) and the portion thereof, if any, which is to be satisfied by delivering and
crediting Securities pursuant to Section 12.2 and will also deliver to the
Trustee any Securities to be so delivered. Such Officers' Certificate shall be
irrevocable and upon its delivery the Company shall be obligated to make the
cash payment or payments therein referred to, if any, on or before the
succeeding sinking fund payment date. In the case of the failure of the Company
to deliver such Officers' Certificate (or, as required by this Indenture, the
Securities and coupons, if any, specified in such Officers' Certificate), the
sinking fund payment due on the succeeding sinking fund payment date for such
series shall be paid entirely in cash and shall be sufficient to redeem the
principal amount of the Securities of such series subject to a mandatory sinking
fund payment without the right to deliver or credit securities as provided in
Section 12.2 and without the right to make the optional sinking fund payment
with respect to such series at such time.

         Any sinking fund payment or payments (mandatory or optional) made in
cash plus any unused balance of any preceding sinking fund payments made with
respect to the Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
immediately following the date of such payment) to the redemption of Securities
of such series at the Redemption Price specified in such Securities with respect
to the sinking fund. Any sinking fund moneys not so applied or allocated by the
Trustee (or, if the Company is acting as its own Paying Agent, segregated and
held in trust by the Company as provided in Section 10.3) for such series and
together with such payment (or such amount so segregated) shall be applied in
accordance with the provisions of this Section 12.3. Any and all sinking fund


<PAGE>   74


                                                                              67



moneys with respect to the Securities of any particular series held by the
Trustee (or if the Company is acting as its own Paying Agent, segregated and
held in trust as provided in Section 10.3) on the last sinking fund payment date
with respect to Securities of such series and not held for the payment or
redemption of particular Securities of such series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent),
together with other moneys, if necessary, to be deposited (or segregated)
sufficient for the purpose, to the payment of the principal of the Securities of
such series at Maturity. The Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 11.3 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 11.4. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Section 11.6. On or before each sinking fund
payment date, the Company shall pay to the Trustee (or, if the Company is acting
as its own Paying Agent, the Company shall segregate and hold in trust as
provided in Section 10.3) in cash a sum in the currency in which Securities of
such series are payable (except as provided pursuant to Section 3.1) equal to
the principal and any interest accrued to the Redemption Date for Securities or
portions thereof to be redeemed on such sinking fund payment date pursuant to
this Section 12.3.

         Neither the Trustee nor the Company shall redeem any Securities of a
series with sinking fund moneys or mail any notice of redemption of Securities
of such series by operation of the sinking fund for such series during the
continuance of a default in payment of interest, if any, on any Securities of
such series or of any Event of Default (other than an Event of Default occurring
as a consequence of this paragraph) with respect to the Securities of such
series, except that if the notice of redemption shall have been provided in
accordance with the provisions hereof, the Trustee (or the Company, if the
Company is then acting as its own Paying Agent) shall redeem such Securities if
cash sufficient for that purpose shall be deposited with the Trustee (or
segregated by the Company) in accordance with the terms of this Article XII.
Except as aforesaid, any moneys in the sinking fund for such series at the time
when any such default or Event of Default shall occur and any moneys thereafter
paid into such sinking fund shall, during the continuance of such default or
Event of Default, be held as security for the payment of the Securities and
coupons, if any, of such series; provided, however, that in case such default or
Event of Default shall have been cured or waived herein, such moneys shall
thereafter be applied on the next sinking fund payment date for the Securities
of such series on which such moneys may be applied pursuant to the provisions of
this Section 12.3.


                                  ARTICLE XIII

                           SUBORDINATION OF SECURITIES

         SECTION 13.1.   Securities Subordinate to Senior Indebtedness.

         The Company covenants and agrees, and each Holder of a Security, by its
acceptance thereof, likewise covenants and agrees, that, to the extent and in
the manner hereinafter set forth in this Article, the payment of the principal
of (and premium, if any) and interest (including any


<PAGE>   75


                                                                              68



Additional Interest) on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
Senior Indebtedness.

         SECTION 13.2. No Payment When Senior Indebtedness in Default; Payment
Over of Proceeds Upon Dissolution, Etc.

         In the event that the Company shall default in the payment of any
principal of (or premium, if any) or interest on any Senior Indebtedness when
the same becomes due and payable, whether at maturity or at a date fixed for
prepayment or by declaration of acceleration or otherwise, then, upon written
notice of such default to the Company by the holders of Senior Indebtedness or
any trustee therefor, unless and until such default shall have been cured or
waived or shall have ceased to exist, no direct or indirect payment (in cash,
property, securities, by set-off or otherwise) shall be made or agreed to be
made on account of the principal of (or premium, if any) or interest on any of
the Securities, or in respect of any redemption, repayment, retirement, purchase
or other acquisition of any of the Securities.

         In the event of (a) any insolvency, bankruptcy, receivership,
liquidation, reorganization, readjustment, composition or other similar
proceedings relating to the Company, its creditors or its property, (b) any
proceeding for the liquidation, dissolution or other winding up of the Company,
voluntary or involuntary, whether or not involving insolvency or bankruptcy
proceedings, (c) any assignment by the Company for the benefit of creditors or
(d) any other marshalling of the assets of the Company (each such event, if any,
herein sometimes referred to as a "Proceeding"), all Senior Indebtedness
(including any interest thereon accruing after the commencement of any such
proceedings) shall first be paid in full before any payment or distribution,
whether in cash, securities or other property, shall be made to any Holder of
any of the Securities on account thereof. Any payment or distribution, whether
in cash, securities or other property (other than securities of the Company or
any other corporation provided for by a plan of reorganization or readjustment
the payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the indebtedness evidenced by the
Securities, to the payment of all Senior Indebtedness at the time outstanding
and to any securities issued in respect thereof under any such plan of
reorganization or readjustment), which would otherwise (but for these
subordination provisions) be payable or deliverable in respect of the Securities
of any series, shall be paid or delivered directly to the holders of Senior
Indebtedness in accordance with the priorities then existing among such holders
until all Senior Indebtedness (including any interest thereon accruing after the
commencement of any Proceeding) shall have been paid in full.

         In the event of any Proceeding, after payment in full of all sums owing
with respect to Senior Indebtedness, the Holders of the Securities, together
with the holders of any obligations of the Company ranking on a parity with the
Securities (which for this purpose only shall include the Allocable Amounts of
Senior Subordinated Debt), shall be entitled to be paid from the remaining
assets of the Company the amounts at the time due and owing on account of unpaid
principal of (and premium, if any) and interest on the Securities and such other
obligations before any payment or other distribution, whether in cash, property
or otherwise, shall be made on account of any capital stock or any obligations
of the Company ranking junior to the Securities and such other obligations. In
the event that, notwithstanding the foregoing, any payment or distribution of
any character or any security, whether in cash, securities or other


<PAGE>   76


                                                                              69



property (other than securities of the Company or any other corporation provided
for by a plan of reorganization or readjustment the payment of which is
subordinate, at least to the extent provided in these subordination provisions
with respect to the indebtedness evidenced by the Securities, to the payment of
all Senior Indebtedness at the time outstanding and to any securities issued in
respect thereof under any such plan of reorganization or readjustment), shall be
received by the Trustee or any Holder in contravention of any of the terms
hereof and before all Senior Indebtedness shall have been paid in full, such
payment or distribution or security shall be received in trust for the benefit
of, and shall be paid over or delivered and transferred to, the holders of the
Senior Indebtedness at the time outstanding in accordance with the priorities
then existing among such holders for application to the payment of all Senior
Indebtedness remaining unpaid, to the extent necessary to pay all such Senior
Indebtedness in full. In the event of the failure of the Trustee or any Holder
to endorse or assign any such payment, distribution or security, each holder of
Senior Indebtedness is hereby irrevocably authorized to endorse or assign the
same.

         The Trustee and Holders will take such action (including, without
limitation, the delivery of this Indenture to an agent for the holders of Senior
Indebtedness or consent to the filing of a financing statement with respect
hereto) as may, in the opinion of counsel designated by the holders of a
majority in principal amount of the Senior Indebtedness at the time outstanding,
be necessary or appropriate to assure the effectiveness of the subordination
effected by these provisions.

         The provisions of this Section 13.2 shall not impair any rights,
interests, remedies or powers of any secured creditor of the Company in respect
of any security interest the creation of which is not prohibited by the
provisions of this Indenture.

         The securing of any obligations of the Company, otherwise raking on a
parity with the Securities or ranking junior to the Securities, shall not be
deemed to prevent such obligations from constituting, respectively, obligations
ranking on a parity with the Securities or ranking junior to the Securities.

         SECTION 13.3. Payment Permitted If No Default.

         Nothing contained in this Article or elsewhere in this Indenture, or in
any of the Securities, shall prevent (a) the Company at any time, except during
the conditions described in the first paragraph of Section 13.2 or the pendency
of any Proceeding referred to in Section 13.2, from making payments at any time
of principal of (and premium, if any) or interest (including Additional
Interest) on the Securities, or (b) the application by the Trustee of any moneys
deposited with it hereunder to the payment of or on account of the principal of
(and premium, if any) or interest (including any Additional Interest) on the
Securities or the retention of such payment by the Holders, if, at the time of
such application by the Trustee, it did not have knowledge that such payment
would have been prohibited by the provisions of this Article.

         SECTION 13.4. Subrogation to Rights of Holders of Senior Indebtedness.

         Subject to the payment in full of all amounts due or to become due on
all Senior Indebtedness, or the provision for such payment in cash or cash
equivalents or otherwise in a


<PAGE>   77


                                                                              70



manner satisfactory to the holders of Senior Indebtedness, the Holders of the
Securities shall be subrogated to the extent of the payments or distributions
made to the holders of such Senior Indebtedness pursuant to the provisions of
this Article (equally and ratably with the holders of all indebtedness of the
Company which by its express terms is subordinated to Senior Indebtedness of the
Company to substantially the same extent as the Securities are subordinated to
the Senior Indebtedness and is entitled to like rights of subrogation by reason
of any payments or distributions made to holders of such Senior Indebtedness) to
the rights of the holders of such Senior Indebtedness to receive payments and
distributions of cash, property and securities applicable to the Senior
Indebtedness until the principal of (and premium, if any) and interest on the
Securities shall be paid in full. For purposes of such subrogation, no payments
or distributions to the holders of the Senior Indebtedness of any cash, property
or securities to which the Holders of the Securities or the Trustee would be
entitled except for the provisions of this Article, and no payments over
pursuant to the provisions of this Article to the holders of Senior Indebtedness
by Holders of the Securities or the Trustee, shall, as among the Company, its
creditors other than holders of Senior Indebtedness, and the Holders of the
Securities, be deemed to be a payment or distribution by the Company to or on
account of the Senior Indebtedness.

         SECTION 13.5. Provisions Solely to Define Relative Rights.

         The provisions of this Article are and are intended solely for the
purpose of defining the relative rights of the Holders of the Securities on the
one hand and the holders of Senior Indebtedness on the other hand. Nothing
contained in this Article or elsewhere in this Indenture or in the Securities is
intended to or shall (a) impair, as between the Company and the Holders of the
Securities, the obligations of the Company, which are absolute and
unconditional, to pay to the Holders of the Securities the principal of (and
premium, if any) and interest (including any Additional Interest) on the
Securities as and when the same shall become due and payable in accordance with
their terms; or (b) affect the relative rights against the Company of the
Holders of the Securities and creditors of the Company other than their rights
in relation to the holders of Senior Indebtedness; or (c) prevent the Trustee or
the Holder of any Security from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture including, without limitation,
filing and voting claims in any Proceeding, subject to the rights, if any, under
this Article of the holders of Senior Indebtedness to receive cash, property and
securities otherwise payable or deliverable to the Trustee or such Holder.

         SECTION 13.6. Trustee to Effectuate Subordination.

         Each Holder of a Security by his or her acceptance thereof authorizes
and directs the Trustee on his or her behalf to take such action as may be
necessary or appropriate to acknowledge or effectuate the subordination provided
in this Article and appoints the Trustee his or her attorney-in-fact for any and
all such purposes.

         SECTION 13.7. No Waiver of Subordination Provisions.

         No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith,


<PAGE>   78


                                                                              71



by any such holder, or by any noncompliance by the Company with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof
that any such holder may have or be otherwise charged with.

         Without in any way limiting the generality of the immediately preceding
paragraph, the holders of Senior Indebtedness may, at any time and from to time,
without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article or
the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (i) change the manner,
place or terms of payment or extend the time of payment of, or renew or alter,
Senior Indebtedness, or otherwise amend or supplement in any manner Senior
Indebtedness or any instrument evidencing the same or any agreement under which
Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing Senior
Indebtedness; (iii) release any Person liable in any manner for the collection
of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights
against the Company and any other Person.

         SECTION 13.8. Notice to Trustee.

         The Company shall give prompt written notice to the Trustee of any fact
known to the Company which would prohibit the making of any payment to or by the
Trustee in respect of the Securities. Notwithstanding the provisions of this
Article or any other provision of this Indenture, the Trustee shall not be
charged with knowledge of the existence of any facts which would prohibit the
making of any payment to or by the Trustee in respect of the Securities, unless
and until the Trustee shall have received written notice thereof from the
Company or a holder of Senior Indebtedness or from any trustee, agent or
representative therefor; provided, however, that if the Trustee shall not have
received the notice provided for in this Section at least two Business Days
prior to the date upon which by the terms hereof any monies may become payable
for any purpose (including, without limitation, the payment of the principal of
(and premium, if any) or interest (including any Additional Interest) on any
Security), then, anything herein contained to the contrary notwithstanding, the
Trustee shall have full power and authority to receive such monies and to apply
the same to the purpose for which they were received and shall not be affected
by any notice to the contrary which may be received by it within two Business
Days prior to such date.

         Subject to the provisions of Section 6.1, the Trustee shall be entitled
to rely on the delivery to it of a written notice by a Person representing
himself to be a holder of Senior Indebtedness (or a trustee or attorney-in-fact
therefor) to establish that such notice has been given by a holder of Senior
Indebtedness (or a trustee or attorney-in-fact therefor). In the event that the
Trustee determines in good faith that further evidence is required with respect
to the right of any Person as a holder of Senior Indebtedness to participate in
any payment or distribution pursuant to this Article, the Trustee may request
such Person to furnish evidence to the reasonable satisfaction of the Trustee as
to the amount of Senior Indebtedness held by such Person, the extent to which
such Person is entitled to participate in such payment or distribution and any
other facts pertinent to the rights of such Person under this Article, and if
such evidence

                                                                              72



is not furnished, the Trustee may defer any payment to such Person pending
judicial determination as to the right of such Person to receive such payment.

         SECTION 13.9. Reliance on Judicial Order or Certificate of Liquidating
Agent.

         Upon any payment or distribution of assets of the Company referred to
in this Article, the Trustee, subject to the provisions of Section 6.1, and the
Holders of the Securities shall be entitled to rely upon any order or decree
entered by any court of competent jurisdiction in which such Proceeding is
pending, or a certificate of the trustee in bankruptcy, receiver, liquidating
trustee, custodian, assignee for the benefit of creditors, agent or other Person
making such payment or distribution, delivered to the Trustee or to the Holders
of Securities, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article.

         SECTION 13.10. Trustee Not Fiduciary for Holders of Senior 
Indebtedness.

         The Trustee, in its capacity as trustee under this Indenture, shall not
be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and
shall not be liable to any such holders if it shall in good faith mistakenly pay
over or distribute to Holders of Securities or to the Company or to any other
Person cash, property or securities to which any holders of Senior Indebtedness
shall be entitled by virtue of this Article or otherwise. With respect to the
Holders of Senior Indebtedness, the Trustee undertakes to perform or to observe
only such of its covenants or obligations as are specifically set forth in this
Article and no implied covenants or obligations with respect to Holders of
Senior Indebtedness shall be read into this Indenture against the Trustee.


         SECTION 13.11. Rights of Trustee as Holder of Senior Indebtedness;
Preservation of Trustee's Rights.

         The Trustee in its individual capacity shall be entitled to all the
rights set forth in this Article with respect to any Senior Indebtedness which
may at any time be held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of
its rights as such holder.

         Nothing in this Article shall apply to claims of, or payments to, the
Trust under or pursuant to Section 6.7.

         SECTION 13.12. Article Applicable to Paying Agents.

         In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article shall in such case (unless the context otherwise
requires) be construed as extending to and including such Paying Agent within
its meaning as fully for all intents and purposes as if such Paying Agent were
named in this Article in addition to or in place of the Trustee.

relating to the registration under the Securities Act of 1933, as amended, of
the Preferred Securities of the Trust and certain other securities and (b) a
Registration Statement on Form 8-A (the "Exchange Act Registration Statement"),
including all pre-effective and post-effective amendments thereto (including the

desirable to cause the Preferred Securities to be listed on any such Exchange or
the NASD's Nasdaq National Market ("NASDAQ"); (iii) to execute and file on
behalf of the Trust such applications, reports, surety bonds, irrevocable

with one or more underwriters relating to the offering of the Preferred
Securities as the Depositor, on behalf of the Trust, may deem necessary or

or state securities or Blue Sky laws, to be executed on behalf of the Trust by a
Trustee, the Depositor and any trustee of the Trust appointed pursuant to

on behalf of the Trust any and all of the foregoing.

                  6. The number of Trustees initially shall be three (3) and
thereafter the number of Trustees shall be such number as shall be fixed from
time to time by a written instrument signed by the Depositor which may increase
or

                                       -2-

decrease the number of Trustees; provided, however, that to the extent required
by the Business Trust Act, one Trustee shall either be a natural person who is a
resident of the State of Delaware or, if not a natural person, an entity which
has its principal place of business in the State of Delaware and otherwise meets
the requirements of applicable Delaware law. Subject to the foregoing, the
Depositor is entitled to appoint or remove without cause any of the Trustees at
any time. Any of the Trustees may resign upon thirty days' prior notice to the
Depositor provided, however, such notice shall not be required if it is waived
by the Depositor.

                  7. This Trust Agreement shall be governed by, and construed in
accordance with, the laws of the State of Delaware (without regard to conflict
of laws principles).

Trustee, the Depositor and any trustee of the Trust appointed pursuant to

or


                                       -2-

decrease the number of Trustees; provided, however, that to the extent required
by the Business Trust Act, one Trustee shall either be a natural person who is a

Depositor is entitled to appoint or remove without cause any of the Trustees at
any time. Any of the Trustees may resign upon thirty days' prior notice to the

accordance with, the laws of the State of Delaware (without regard to conflict
of laws principles).

taken by the Depositor in furtherance of the following prior to the date of this
Trust Agreement are hereby ratified and confirmed in all respects):

                        (i) the preparation and filing by the Trust with the
         Commission and the execution on behalf of the Trust of a registration
         statement on the appropriate form in relation to the Preferred
         Securities, including any amendments thereto;

                       (ii) the determination of the states in which to take
         appropriate action to qualify or register for sale all or part of the
         Preferred Securities and the determination of any and all such acts,
         other than actions which must be taken by or on behalf of the Trust,
         and the advice to the Trustees of actions they must take on behalf of

         Stock Exchange or any other national stock exchange or the Nasdaq
         National Market or any other automated quotation system for listing
         upon notice of issuance of any Preferred Securities and filing with
         such exchange or self-regulatory organization such notifications and
         documents as may be necessary from time to time to maintain such
         listing;

                        (iv) the negotiation of the terms of, and the execution
         and delivery of, the Underwriting Agreement providing for the sale of
         the Preferred Securities; and

                         (v) the taking of any other actions necessary or

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 be taxable as a
corporation 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.

All monies and other property deposited or held from time to time in the Payment

                            DISTRIBUTIONS; REDEMPTION

         SECTION 4.1  Distributions.

         (a) The Trust Securities represent undivided beneficial ownership
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 ________ __, 199_, and, except in the event (and to the
         extent) that the Depositor exercises its right to defer the payment of

         [quarterly] [semi-annually] [monthly] in

                                                                              16



        arrears on _________________,  commencing on _______, 199_. 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 Distribution
         period shall be computed on the basis of a 360-day year of twelve
         30-day months. The amount of Distributions for any partial Distribution
         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.

         (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 15 days prior to the relevant
Distribution Date (whether or not such record date is a Business Day).

         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 a Like Amount of Trust

at such Holder's address appearing in the Security Register. All notices of
redemption shall state:

                         (i) the Redemption Date;



<PAGE>   24


                                                                              17



                        (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;

                         (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; and

                        (vi) if the Preferred Securities are no longer in
         book-entry-only form, the place and address where the Holders shall
         surrender their Preferred Securities Certificates.

         (c) The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption or payment at stated maturity of 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, New York City time, on the
Redemption Date, subject to Section 4.2(c), the Property Trustee will, so long
as the Preferred Securities are in book-entry-only form, 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
instructions and authority to pay the Redemption Price to the Holders thereof.
If the Preferred Securities are no longer in book-entry-only 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 Securities
Register for the Trust Securities on the relevant record dates for the related
Distribution Dates. If notice of redemption shall have been given and funds
deposited as required, then upon the date of such deposit, all rights of
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
thereon, and such Trust Securities will cease to be outstanding. In the event
that any date on which any Redemption Price is payable is not a Business Day,
then payment of the Redemption Price payable on such date will be made on the
next succeeding day that is a Business Day (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


<PAGE>   25


                                                                              18



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 as the Property Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to $_____ or an
integral multiple of $_____ in excess thereof) of the Liquidation Amount of
Preferred Securities of a denomination larger than $_____. 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,

Securities for all Distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all Outstanding Preferred Securities then called for redemption, shall
have been made or provided for, and all funds immediately available to the
Property Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

         (b) In the case of the occurrence of any Event of Default resulting
from 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.

         SECTION 4.4  Payment Procedures.

         Payments of Distributions (including Additional Amounts, if applicable)
in respect of the Preferred Securities shall be made by wire transfer, direct
deposit or 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 in writing 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, if any, and
the information required to be provided by the Trust 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 Issuer Trust.

         Upon receipt under the Debentures of Additional Sums, the Property
Trustee shall promptly pay any taxes, duties or governmental charges of
whatsoever nature (other than withholding taxes) imposed on the 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
shall be reduced by the amount of any corresponding payment such Holder (or an
Owner with respect to the Holder's Preferred Securities) has directly received
pursuant to Section 5.8 of the Indenture or Section 5.14 of this Trust
Agreement.

         Upon the creation of the Trust and the contribution by the Depositor

or its agent and (ii) authenticated by the Property Trustee by manual or
facsimile signature of an authorized signatory thereof and, if executed by such

been affixed, authorized to sign on behalf of the Trust or the Property Trustee
or, if executed on behalf of the Trust or the Property Trustee by facsimile,
countersigned by a transfer agent or its agent, shall be validly issued and
entitled to the benefits of this Trust Agreement, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
delivery of such Trust Securities Certificates or did not hold such offices at
the date of delivery of such Trust Securities Certificates. A transferee of a
Trust Securities Certificate shall become a Securityholder, and shall be
entitled to the rights and subject to the obligations of a Securityholder
hereunder, upon due

                                                                              21



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.

         On the Closing Date, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to or
upon the written order of the Depositor, signed by its chairman of the board,
its chief executive officer, its president, any executive vice president, any
senior 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
transfer agent and registrar designated by the Depositor (the "Securities
Registrar"), subject to such reasonable regulations as it may prescribe, shall
provide for the registration of 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 on behalf of the Trust
(and if executed on behalf of the Trust by a facsimile signature, such
certificate shall be countersigned by a transfer agent or its agent) 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
during a period beginning at the opening of business 15 days before the day of
selection for such redemption.

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

                                                                              22



disposed of by an Administrative Trustee or the Securities Registrar in
accordance with such Person's customary practice.

         No service charge shall be made for any registration of transfer or
exchange of 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 by manual or facsimile signature and, if executed on behalf
of the Trust by facsimile signature, such certificate shall be countersigned by
a transfer agent, 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 Trust Property, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

         SECTION 5.6  Persons Deemed Securityholders.

         The Trustees or the Securities Registrar shall treat the Person in
whose name any Trust Securities 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.

         Each Holder 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.

                                                                              23



         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 Bank of New York, 101
Barclay Street, Floor 21 West, New York, New York 10286, Attn: Corporate Trust
Administration, as its principal corporate trust office for such purposes. The
Administrative Trustees shall give prompt written notice to the Depositor, the
Property Trustee 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 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 Bank, and any co-paying agent chosen by the Bank, 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 Bank 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 resignation or 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, and any
Paying Agent shall be bound by the requirements with respect to paying agents of
securities issued pursuant to the Trust Indenture Act. 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.

         On the Closing Date, the Depositor shall acquire and retain beneficial
and record ownership of the Common Securities. To the fullest extent permitted
by law, other than a

                                                                              24



transfer in connection with a consolidation or merger of the Depositor into
another Person, or any conveyance, transfer or lease by the Depositor of its
properties and assets substantially as an entirety to any Person, pursuant to
Section 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 TO ANY PERSON".

         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 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 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 and the giving of instructions or
         directions to Owners of Preferred Securities evidenced by Book-Entry
         Preferred Securities Certificates) as the sole Holder of Preferred
         Securities evidenced by 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.

         (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.

         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
Administrative Trustees in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interest of the Owners of
Preferred Securities Certificates, then the Administrative Trustees shall notify
the other Trustees and the Clearing Agency, and the Clearing Agency, in
accordance with its customary rules and procedures, shall notify all Clearing
Agency Participants for whom it holds Preferred Securities 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 Administrative Trustees 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 which, if executed on behalf of the Trust by facsimile,
shall be countersigned by a transfer agent or its agent. Neither the Securities
Registrar nor the Trustees shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Preferred Securities
Certificates, the Trustees shall recognize the Holders of the Definitive
Preferred Securities Certificates as Securityholders. The Definitive Preferred
Securities Certificates shall be typewritten, printed, lithographed or engraved
or may be produced in any other manner as is reasonably acceptable to the
Administrative Trustees that meets the requirements of any stock exchange or
automated quotation system on which the Preferred Securities are then listed or
approved for trading, as evidenced by the execution thereof by the
Administrative Trustees or any one of them.

         SECTION 5.14  Rights of Securityholders.



<PAGE>   33


                                                                              26



         (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 ownership 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 Preferred Securities, in
their capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

         (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 as set forth in the Indenture, provided that
the payment of principal, premium 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



<PAGE>   34


                                                                              27



                        (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, premium or interest (unless 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
annulled as provided in Section 5.3 of the Indenture and the Company has paid or
deposited with the Debenture Trustee a sum sufficient to pay all overdue
installments of interest (including any Additional Interest (as defined in the
Indenture)) on the Debentures, 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 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) 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 of Outstanding Preferred Securities 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

                                                                              28



Holder of the principal amount of or premium 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.

         SECTION 5.15  CUSIP Numbers.

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



                                   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 10.3
and in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

         (b) So long as any Debentures are held by the Property Trustee, 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 waiveable 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


<PAGE>   36


                                                                              29



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 Administrative 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 or cause the Trust to be taxable as a corporation 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 or to be taxable as a corporation for United
States federal income tax purposes.

         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 10.9 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 the Preferred
Securityholders 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.

         Preferred Securityholders 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 Preferred Securityholders.



<PAGE>   37


                                                                              30



         If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding at
least a majority of the Outstanding Preferred Securities (based upon their
Liquidation Amount) held by holders of record of Outstanding Preferred
Securities 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 $_____ 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 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 at least a majority of all
Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
vote in respect of such action (or such larger proportion thereof as shall be
required by any express provision of this Trust Agreement) shall consent to the
action in writing.

         SECTION 6.7  Record Date for Voting and Other Purposes.

         For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate in
any Distribution on the Trust Securities in respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, the Administrative 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


<PAGE>   38


                                                                              31



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 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


<PAGE>   39


                                                                              32



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.

         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

obligations as one of the Trustees under this Trust Agreement.

                                  ARTICLE VIII

                                  THE TRUSTEES

         SECTION 8.1  Certain Duties and Responsibilities.

         (a) The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee, by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
them. Whether or not therein expressly so provided, every provision of this
Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustees shall be subject to the provisions of this
Section. Nothing in this Trust Agreement shall be construed to release 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;



<PAGE>   42


                                                                              35



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

                       (iii) the Property Trustee's sole duty with respect to
         the custody, safekeeping 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
         in writing 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.

         Within ten 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 10.9, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived.

         Within five Business Days after the receipt of notice of the
Depositor's exercise of its right to defer the payment of interest on the
Debentures pursuant to the Indenture, the Administrative Trustee shall transmit,
in the manner and to the extent provided in Section 10.9, notice of such
exercise to the Securityholders and the Property Trustee, unless such exercise
shall have been revoked.

         SECTION 8.3  Certain Rights of Property Trustee.

         Subject to the provisions of Section 8.1:

         (a) the Property Trustee may rely and shall be protected in acting or
refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate,


<PAGE>   43


                                                                              36



statement, instrument, opinion, report, notice, request, consent, order,
appraisal, bond, debenture, note, other evidence of indebtedness or other paper
or document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

         (b) if (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action or
(ii) in construing any of the provisions of this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to which
the 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 reregistration thereof;

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

         (g) the Property Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the


<PAGE>   44


                                                                              37



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 written instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request written instructions from the Holders of the Trust
Securities which written 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 written instructions are
received, and (iii) shall be protected in acting in accordance with such written
instructions; and

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

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

         SECTION 8.4  Not Responsible for Recitals or Issuance of Securities.

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

                                                                              38




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

         SECTION 8.6  Compensation; Indemnity; Fees.
 
         The Holder of the Common Securities shall:

         (a) pay to the Trustees from time to time such compensation as shall be
agreed in writing with the Holder of the Common Securities 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);

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

         (c) to the fullest extent permitted by applicable law, 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 and all
loss, damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by this Trust Agreement, except
that no Indemnified Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Indemnified Person by reason of
negligence or willful misconduct with respect to such acts or omissions. When
the Property Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(4) or Section 5.1(5) of the Indenture,
the expenses (including the reasonable charges and expenses of its counsel) and
the compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

         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.

                                                                              39



         The Depositor and any Trustee (in the case of the Property Trustee,
subject to Section 8.8 hereof) 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 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.

                                                                              40




         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 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.



<PAGE>   48


                                                                              41



         (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 Common
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 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). An Administrative Trustee may
be removed by the Common Securityholder at any time. 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 such removal, the
Relevant Trustee may petition, at the expense of the Trust, any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.



<PAGE>   49


                                                                              42



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

         Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative 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 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


<PAGE>   50


                                                                              43



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 written request of the Trust or any successor Relevant
Trustee such retiring Relevant Trustee shall, upon payment of its charges, duly
assign, transfer and deliver to such successor Relevant Trustee all Trust
Property, all proceeds thereof and money held by such retiring Relevant Trustee
hereunder with respect to the Trust Securities and the Trust.

         Upon written 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 preceding paragraph.

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

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

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

         SECTION 8.13 Preferential Collection of Claims Against Depositor or
Trust.

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



<PAGE>   51


                                                                              44



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

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Property Trustee and, in the event the
Property Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Property Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel, and any other amounts due the Property Trustee.

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

         SECTION 8.14  Reports by Property Trustee.

         (a) The Property Trustee shall transmit to Securityholders such reports
concerning the Property Trustee and its actions under this Trust Agreement as
may be required pursuant to the Trust Indenture Act at the times and in the
manner provided pursuant thereto. If required by Section 313(a) of the Trust
Indenture Act, the Property Trustee shall, within sixty days after each May 15
following the date of this Trust Agreement deliver to Securityholders a brief
report, dated as of such May 15, which complies with the provisions of such
Section 313(a).

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

         SECTION 8.15  Reports to the Property Trustee.

         The Depositor and the Administrative Trustees on behalf of the Trust
shall provide to the Property Trustee such documents, reports and information as
required by Section 314 of the Trust Indenture Act (if any) and the compliance
certificate required by Section 314(a) of the Trust Indenture Act in the form,
in the manner and at the times required by Section 314 of the Trust Indenture
Act. Delivery of such reports, information and documents to the Property Trustee
is for informational purposes only and the Property Trustee's receipt of


<PAGE>   52


                                                                              45



such shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the
Trust's compliance with any of its covenants hereunder (as to which the Property
Trustee is entitled to rely exclusively on Officers' Certificates).

         SECTION 8.16  Evidence of Compliance with Conditions Precedent.

         Each of the Depositor and the Administrative Trustees on behalf of the
Trust shall provide to the Property Trustee such evidence of compliance with any
conditions precedent, if any, provided for in this Trust Agreement that relate
to any of the matters set forth in Section 314 (c) of the Trust Indenture Act.
Any certificate or opinion required to be given by an officer pursuant to
Section 314(c)(1) of the Trust Indenture Act shall be given in the form of an
Officers' Certificate.

         SECTION 8.17  Number of Trustees.

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

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

         (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to dissolve, terminate or 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
with applicable law, delegate to any other natural person over the age of 21 his
or her power for the purpose of executing any documents contemplated in Section
2.7(a), including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing; and

         (b) The Administrative Trustees shall have power to delegate from time
to time to such of their number or to the Depositor the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the Administrative Trustees or


<PAGE>   53


                                                                              46



otherwise as the Administrative Trustees may deem expedient, to the extent such
delegation is not prohibited by applicable law or contrary to the provisions of
this Trust Agreement, as set forth herein.

         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

                        (iv) provide such information with respect to the
         mechanics by which Holders may exchange Trust Securities Certificates
         for Debentures, or if Section 9.4(d) applies 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 Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

         (c) Except where Section 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 or
traded, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on which
a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal will be made to Holders of Trust Securities
Certificates with respect to such Debentures) and (v) all rights of
Securityholders holding Trust Securities will

                                                                              48



cease, except the right of such Securityholders to receive 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 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, the Preferred Securities shall have a priority over the 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 Person, except pursuant
to this Article IX. 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 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

                                                                              49



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 Person or
permit any other Person 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 taxable as
a corporation or to be classified as other than a grantor trust for United
States federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

         SECTION 10.1  Limitation of Rights of Securityholders.

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

         SECTION 10.2  Liability of the Common Securityholder.

         The Holder of the Common Securities shall be liable for all of the
debts and obligations of the Trust (other than with respect to the Securities)
to the extent not satisfied out of the Trust's assets.

         SECTION 10.3   Amendment.

         (a) This Trust Agreement may be amended from time to time by the
Property Trustee, the Administrative Trustees and the Depositor, without the
consent of any

                                                                              50



Securityholders, (i) to cure any ambiguity, correct or supplement any provision
herein which may be inconsistent with any other provision herein, or to make any
other provisions with respect to matters or questions arising under this Trust
Agreement, which shall not be inconsistent with the other provisions of this
Trust Agreement, or (ii) to modify, eliminate or add to any provisions of this
Trust Agreement to such extent as shall be necessary to ensure that the Trust
will be classified for United States federal income tax purposes as a grantor
trust and not be taxable as a corporation at all times that any Trust Securities
are outstanding or to ensure that the Trust will not be required to register as
an investment company under the 1940 Act; provided, however, that in the case of
clause (i) or clause (ii), such action shall not adversely affect in any
material respect the interests of any Securityholder, and any amendments of this
Trust Agreement shall become effective when notice thereof is given to the
Securityholders.

         (b) Except as provided in Section 10.3(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii)
receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's exemption from status of an
Investment company under the 1940 Act or the Trust's status as a grantor trust
for United States federal income tax purposes and will not result in the Trust
being taxable as a corporation for United States federal income tax purposes.

         (c) In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.3 or 6.6 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
paragraph (c) of this Section 10.3 may not be amended.

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

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

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

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

         SECTION 10.4  Separability.

         In case any provision in this Trust Agreement or in the Trust

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

         SECTION 10.5  Governing Law.

PRINCIPLES).

         SECTION 10.6  Payments Due on Non-Business Day.

         If the date fixed for any payment on any Trust Security shall be a day
that is not a Business Day, then such payment need not be made on such date but
may be made on the next succeeding day that is a Business Day (except as
otherwise provided in Sections 4.1(a) and 4.2(d)), with the same force and
effect as though made on the date fixed for such payment, and no interest shall
accrue thereon for the period after such date.

         SECTION 10.7  Successors.

         This Trust Agreement shall be binding upon and shall inure to the
benefit of any successor to the Depositor, the Trust or the Relevant Trustee,
including any successor by operation of law. Except in connection with a
consolidation, merger or sale involving the Depositor that is permitted under
Article Eight of the Indenture and pursuant to which the assignee agrees in
writing to perform the Depositor's obligations hereunder, the Depositor shall
not assign its obligations hereunder.

         SECTION 10.10  Agreement Not to Petition.

         Each of the Trustees and the Depositor agree for the benefit of the
Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Depositor takes action in violation of this Section 10.10, the
Property Trustee agrees, for the benefit of Securityholders, that at the expense
of the Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Trust
or the commencement of such action and raise the defense that the Depositor has
agreed in writing not to take such action and should be stopped and precluded
therefrom and such other defenses, if any, as counsel for the Trustee or the
Trust may assert. The provisions of this Section 10.10 shall survive the
termination of this Trust Agreement.

Agreement by any of the provisions of the Trust Indenture Act, such required or
deemed provision shall control. If any provision of this Trust Agreement
modifies or excludes any provision of the Trust Indenture Act which may be so
modified or excluded, the latter provision shall be deemed to apply to this
Trust Agreement as so modified or excluded, as the case may be.

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

         SECTION 10.12 Acceptance of Terms of Trust Agreement, Guarantee and
Indenture.

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

SUCH TRUST SECURITY OF ALL THE TERMS AND PROVISIONS OF THIS TRUST AGREEMENT AND
AGREEMENT TO THE SUBORDINATION PROVISIONS AND OTHER TERMS OF THE GUARANTEE AND
THE INDENTURE, AND SHALL CONSTITUTE THE AGREEMENT OF THE TRUST, SUCH

                  Re:      First Tennessee Capital I
                           ____% Preferred Securities, Series __
                           CUSIP

Ladies and Gentlemen:

                  The purpose of this letter is to set forth certain matters
relating to the issuance and deposit with The Depository Trust Company ("DTC")
of the book-entry-only portion of the _____% Preferred Securities, Series _ (the
"Preferred Securities"), of First Tennessee Capital I, a statutory business
trust formed under the laws of the State of Delaware (the "Issuer"), governed by
the Amended and Restated Trust Agreement, dated as of _________ __, 199_,
between First Tennessee National Corporation ("the Corporation"), as Depositor,
The Bank of New York, as Property Trustee, and The Bank of New York (Delaware),
as Delaware Trustee. The payment of distributions on the Preferred Securities
and payments due upon liquidation of the Issuer or redemption of the Preferred
Securities, to the extent the Issuer has funds available for the payment
thereof, are guaranteed by the Corporation to the extent set forth in a
Guarantee Agreement, dated as of ________ __, 199_, between the Corporation and
The Bank of New York, as Guarantee Trustee with respect to the Preferred
Securities. The Corporation and the Issuer propose to sell the Preferred
Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement, dated as of _________ __, 199_, by and among the
Underwriters, the Issuer and the Corporation, and the Underwriters wish to take
delivery of the Preferred

                                       B-1

Securities through DTC. The Bank of New York is acting as transfer agent and
registrar with respect to the Preferred Securities (the "Transfer Agent and
Registrar").

                  To induce DTC to accept the Preferred Securities as eligible
for deposit at DTC, and to act in accordance with DTC's rules with respect to
the Preferred Securities, the Issuer and the Transfer Agent and Registrar make
the following representations to DTC:

                  1. Prior to the closing of the sale of the Preferred
Securities to the Underwriters on __________ __, 199_, there shall be deposited
with, or held by the Transfer Agent and Registrar as custodian for, DTC one or
more global certificates (individually and collectively, the "Global
Certificate") registered in the name of DTC's nominee, Cede & Co., representing
an aggregate of ________ 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 Issuer
         or its agent for registration of transfer, exchange, or payment, and
         any certificate issued is registered in the name of Cede & Co. or in
         such other name as is requested by an authorized representative of DTC
         (and any payment is made to Cede & Co. or to such other entity as is
         requested by an authorized representative of DTC), ANY TRANSFER,
         PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
         IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an
         interest herein.

                  2. The Amended and Restated Trust Agreement of the Issuer
provides for the voting by holders (with no provision for revocation of consents
or votes by subsequent holders) of the 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 Preferred Securities outstanding, the
Issuer or the Transfer Agent and Registrar shall send DTC a notice of such event
as soon as possible, but at least 5 business days prior to the effective date of
such event.

                  4. In the event of any distribution on, or an offering or
issuance of rights with respect to, the 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 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 Preferred
Securities or published by or on behalf of the Issuer (whether by mail or
publication, the "Publication Date"). Such notice

                                       B-2

<PAGE>   68



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

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

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

                                    Call Notification Department

                                    Garden City, New York 11530-4719

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

                                       B-3

<PAGE>   69



receipt of such notice shall be confirmed by telephoning (212) 709-6884, or by
mail or any other means to:

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

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

                  8. Distribution payments or other cash payments with respect
to the Preferred Securities shall be governed by DTC's current Principal and
Income Payments Rider, a copy of which is attached hereto as Annex I. For
purposes of this letter, the term "Agent" used in Annex I shall be deemed to
refer to The Bank of New York or any successor Property Trustee under the
Amended and Restated Trust Agreement.

                  9. DTC may 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 Preferred Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion: (a) may request the Issuer or the Transfer
Agent and Registrar to issue and countersign a new Global Certificate; or (b)
may make an appropriate notation on the Global Certificate indicating the date
and amount of such reduction.

                  11. DTC may discontinue its services as a securities
depositary with respect to the Preferred Securities at any time by giving
reasonable 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 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 book-entry settlement for the Preferred Securities, make
available one or more separate global certificates evidencing Preferred
Securities to any Participant having Preferred Securities credited to its DTC
account, or issue definitive 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

                                       B-4

<PAGE>   70



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 Preferred Securities shall be able to obtain definitive 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 First Tennessee Capital I.

         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.

         (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 15 days prior to the relevant
Distribution Date (whether or not such record date is a Business Day).

         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 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;



<PAGE>   24


                                                                              17



                        (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;

                         (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; and

                        (vi) if the Preferred Securities are no longer in
         book-entry-only form, the place and address where the Holders shall
         surrender their Preferred Securities Certificates.

         (c) The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption or payment at stated maturity of 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, New York City time, on the
Redemption Date, subject to Section 4.2(c), the Property Trustee will, so long
as the Preferred Securities are in book-entry-only form, 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
instructions and authority to pay the Redemption Price to the Holders thereof.
If the Preferred Securities are no longer in book-entry-only 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 Securities
Register for the Trust Securities on the relevant record dates for the related
Distribution Dates. If notice of redemption shall have been given and funds
deposited as required, then upon the date of such deposit, all rights of
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
thereon, and such Trust Securities will cease to be outstanding. In the event
that any date on which any Redemption Price is payable is not a Business Day,
then payment of the Redemption Price payable on such date will be made on the
next succeeding day that is a Business Day (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


<PAGE>   25


                                                                              18



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 as the Property Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to $_____ or an
integral multiple of $_____ in excess thereof) of the Liquidation Amount of
Preferred Securities of a denomination larger than $_____. 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


<PAGE>   26


                                                                              19



Securities for all Distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all Outstanding Preferred Securities then called for redemption, shall
have been made or provided for, and all funds immediately available to the
Property Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

         (b) In the case of the occurrence of any Event of Default resulting
from 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.

         SECTION 4.4  Payment Procedures.

         Payments of Distributions (including Additional Amounts, if applicable)
in respect of the Preferred Securities shall be made by wire transfer, direct
deposit or 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 in writing 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, if any, and
the information required to be provided by the Trust 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 Issuer Trust.

         Upon receipt under the Debentures of Additional Sums, the Property
Trustee shall promptly pay any taxes, duties or governmental charges of
whatsoever nature (other than withholding taxes) imposed on the 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
shall be reduced by the amount of any corresponding payment such Holder (or an
Owner with respect to the Holder's Preferred Securities) has directly received
pursuant to Section 5.8 of the Indenture or Section 5.14 of this Trust
Agreement.

         Upon the creation of the Trust and the contribution by the Depositor

or its agent and (ii) authenticated by the Property Trustee by manual or
facsimile signature of an authorized signatory thereof and, if executed by such
authorized signatory of the Property Trustee by facsimile, countersigned by a

been affixed, authorized to sign on behalf of the Trust or the Property Trustee
or, if executed on behalf of the Trust or the Property Trustee by facsimile,
countersigned by a transfer agent or its agent, shall be validly issued and
entitled to the benefits of this Trust Agreement, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
delivery of such Trust Securities Certificates or did not hold such offices at
the date of delivery of such Trust Securities Certificates. A transferee of a
Trust Securities Certificate shall become a Securityholder, and shall be
entitled to the rights and subject to the obligations of a Securityholder
hereunder, upon due

                                                                              21



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.

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

         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
transfer agent and registrar designated by the Depositor (the "Securities
Registrar"), subject to such reasonable regulations as it may prescribe, shall
provide for the registration of 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 on behalf of the Trust
(and if executed on behalf of the Trust by a facsimile signature, such
certificate shall be countersigned by a transfer agent or its agent) 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
during a period beginning at the opening of business 15 days before the day of
selection for such redemption.

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

                                                                              22



disposed of by an Administrative Trustee or the Securities Registrar in
accordance with such Person's customary practice.

         No service charge shall be made for any registration of transfer or
exchange of 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 by manual or facsimile signature and, if executed on behalf
of the Trust by facsimile signature, such certificate shall be countersigned by
a transfer agent, 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 Trust Property, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

         SECTION 5.6  Persons Deemed Securityholders.

         The Trustees or the Securities Registrar shall treat the Person in
whose name any Trust Securities 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.

         Each Holder 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.



<PAGE>   30


                                                                              23



         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 Bank of New York, 101
Barclay Street, Floor 21 West, New York, New York 10286, Attn: Corporate Trust
Administration, as its principal corporate trust office for such purposes. The
Administrative Trustees shall give prompt written notice to the Depositor, the
Property Trustee 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 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 Bank, and any co-paying agent chosen by the Bank, 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 Bank 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 resignation or 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, and any
Paying Agent shall be bound by the requirements with respect to paying agents of
securities issued pursuant to the Trust Indenture Act. 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.

         On the Closing Date, the Depositor shall acquire and retain beneficial
and record ownership of the Common Securities. To the fullest extent permitted
by law, other than a


<PAGE>   31


                                                                              24



transfer in connection with a consolidation or merger of the Depositor into
another Person, or any conveyance, transfer or lease by the Depositor of its
properties and assets substantially as an entirety to any Person, pursuant to
Section 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 TO ANY PERSON".

         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 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 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 and the giving of instructions or
         directions to Owners of Preferred Securities evidenced by Book-Entry
         Preferred Securities Certificates) as the sole Holder of Preferred
         Securities evidenced by 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.

         (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.

         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
Administrative Trustees in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interest of the Owners of
Preferred Securities Certificates, then the Administrative Trustees shall notify
the other Trustees and the Clearing Agency, and the Clearing Agency, in
accordance with its customary rules and procedures, shall notify all Clearing
Agency Participants for whom it holds Preferred Securities 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 Administrative Trustees 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 which, if executed on behalf of the Trust by facsimile,
shall be countersigned by a transfer agent or its agent. Neither the Securities
Registrar nor the Trustees shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Preferred Securities
Certificates, the Trustees shall recognize the Holders of the Definitive
Preferred Securities Certificates as Securityholders. The Definitive Preferred
Securities Certificates shall be typewritten, printed, lithographed or engraved
or may be produced in any other manner as is reasonably acceptable to the
Administrative Trustees that meets the requirements of any stock exchange or
automated quotation system on which the Preferred Securities are then listed or
approved for trading, as evidenced by the execution thereof by the
Administrative Trustees or any one of them.

         SECTION 5.14  Rights of Securityholders.



<PAGE>   33


                                                                              26



         (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 ownership 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 Preferred Securities, in
their capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

         (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 as set forth in the Indenture, provided that
the payment of principal, premium 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



<PAGE>   34


                                                                              27



                  (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, premium or interest (unless 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
annulled as provided in Section 5.3 of the Indenture and the Company has paid or
deposited with the Debenture Trustee a sum sufficient to pay all overdue
installments of interest (including any Additional Interest (as defined in the
Indenture)) on the Debentures, 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 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) 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 of Outstanding Preferred Securities 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


<PAGE>   35


                                                                              28



Holder of the principal amount of or premium 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.

         SECTION 5.15  CUSIP Numbers.

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



                                   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 10.3
and in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

         (b) So long as any Debentures are held by the Property Trustee, 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 waiveable 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


<PAGE>   36


                                                                              29



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 Administrative 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 or cause the Trust to be taxable as a corporation 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 or to be taxable as a corporation for United
States federal income tax purposes.

         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 10.9 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 the Preferred
Securityholders 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.

         Preferred Securityholders 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 Preferred Securityholders.



<PAGE>   37


                                                                              30



         If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding at
least a majority of the Outstanding Preferred Securities (based upon their
Liquidation Amount) held by holders of record of Outstanding Preferred
Securities 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 $_____ 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 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 at least than a majority of
all Outstanding Trust Securities (based upon their Liquidation Amount) entitled
to vote in respect of such action (or such larger proportion thereof as shall be
required by any express provision of this Trust Agreement) shall consent to the
action in writing.

         SECTION 6.7  Record Date for Voting and Other Purposes.

         For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate in
any Distribution on the Trust Securities in respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, the Administrative 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


<PAGE>   38


                                                                              31



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 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


<PAGE>   39


                                                                              32



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.

         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

                                  ARTICLE VIII

                                  THE TRUSTEES

         SECTION 8.1  Certain Duties and Responsibilities.

         (a) The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee, by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
them. Whether or not therein expressly so provided, every provision of this
Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustees shall be subject to the provisions of this
Section. Nothing in this Trust Agreement shall be construed to release 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;

                                                                              35



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

                      
                        (iii) the Property Trustee's sole duty with respect to
         the custody, safekeeping 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
         in writing 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.

         Within ten 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 10.9, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived.

         Within five Business Days after the receipt of notice of the
Depositor's exercise of its right to defer the payment of interest on the
Debentures pursuant to the Indenture, the Administrative Trustee shall transmit,
in the manner and to the extent provided in Section 10.9, notice of such
exercise to the Securityholders and the Property Trustee, unless such exercise
shall have been revoked.

         SECTION 8.3  Certain Rights of Property Trustee.

         Subject to the provisions of Section 8.1:

         (a) the Property Trustee may rely and shall be protected in acting or

auditors or any other certificate,

                                                                              36



statement, instrument, opinion, report, notice, request, consent, order,
appraisal, bond, debenture, note, other evidence of indebtedness or other paper
or document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

         (b) if (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action or
(ii) in construing any of the provisions of this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to which
the 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 reregistration thereof;

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

         (g) the Property Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the


<PAGE>   44


                                                                              37



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 written instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request written instructions from the Holders of the Trust
Securities which written 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 written instructions are
received, and (iii) shall be protected in acting in accordance with such written
instructions; and

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

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

         SECTION 8.4  Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Trust Securities Certificates
shall be taken as the statements of the Trust, and the Trustees do not assume

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

         SECTION 8.5  May Hold Securities.


<PAGE>   45


                                                                              38




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

         SECTION 8.6  Compensation; Indemnity; Fees.

         The Holder of the Common Securities shall:

         (a) pay to the Trustees from time to time such compensation as shall be
agreed in writing with the Holder of the Common Securities 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);

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

         (c) to the fullest extent permitted by applicable law, 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 and all
loss, damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by this Trust Agreement, except
that no Indemnified Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Indemnified Person by reason of
negligence or willful misconduct with respect to such acts or omissions. When
the Property Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(4) or Section 5.1(5) of the Indenture,
the expenses (including the reasonable charges and expenses of its counsel) and
the compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

         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.

                                                                              39



         The Depositor and any Trustee (in the case of the Property Trustee,
subject to Section 8.8 hereof) 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 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.

                                                                              40




         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 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.



<PAGE>   48


                                                                              41



         (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 Common
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 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). An Administrative Trustee may
be removed by the Common Securityholder at any time. 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 such removal, the
Relevant Trustee may petition, at the expense of the Trust, any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.



<PAGE>   49


                                                                              42



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

         Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative 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 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


<PAGE>   50


                                                                              43



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 written request of the Trust or any successor Relevant
Trustee such retiring Relevant Trustee shall, upon payment of its charges, duly
assign, transfer and deliver to such successor Relevant Trustee all Trust
Property, all proceeds thereof and money held by such retiring Relevant Trustee
hereunder with respect to the Trust Securities and the Trust.

         Upon written 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 preceding paragraph.

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

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

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

         SECTION 8.13 Preferential Collection of Claims Against Depositor or
Trust.

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



<PAGE>   51


                                                                              44



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

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Property Trustee and, in the event the
Property Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Property Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel, and any other amounts due the Property Trustee.

         Nothing herein contained shall be deemed to authorize the Property
Trustee to authorize or consent to or accept or adopt on behalf of any Holder

         SECTION 8.14  Reports by Property Trustee.

         (a) The Property Trustee shall transmit to Securityholders such reports
concerning the Property Trustee and its actions under this Trust Agreement as
may be required pursuant to the Trust Indenture Act at the times and in the

Indenture Act, the Property Trustee shall, within sixty days after each May 15
following the date of this Trust Agreement deliver to Securityholders a brief

Section 313(a).

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

         SECTION 8.15  Reports to the Property Trustee.

         The Depositor and the Administrative Trustees on behalf of the Trust
shall provide to the Property Trustee such documents, reports and information as
required by Section 314 of the Trust Indenture Act (if any) and the compliance
certificate required by Section 314(a) of the Trust Indenture Act in the form,

such shall not constitute constructive notice of any information contained

Trust's compliance with any of its covenants hereunder (as to which the Property
Trustee is entitled to rely exclusively on Officers' Certificates).

         SECTION 8.16  Evidence of Compliance with Conditions Precedent.

         Each of the Depositor and the Administrative Trustees on behalf of the
Trust shall provide to the Property Trustee such evidence of compliance with any

may be the same Person.

         (b) If a Trustee ceases to hold office for any reason and the number of

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

         (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to dissolve, terminate or 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
with applicable law, delegate to any other natural person over the age of 21 his

Commission, or making any other governmental filing; and

         (b) The Administrative Trustees shall have power to delegate from time
to time to such of their number or to the Depositor the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the Administrative Trustees or

                                                                              46



otherwise as the Administrative Trustees may deem expedient, to the extent such

this Trust Agreement, as set forth herein.


                                   ARTICLE IX

                       TERMINATION, LIQUIDATION AND MERGER

         SECTION 9.1  Termination Upon Expiration Date.

         Unless earlier terminated, the Trust shall automatically terminate on
____________, 20__ (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 Holder of the Common Securities;

         (b) the written direction to the Property Trustee from the Depositor at
any time to terminate the Trust and, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, distribute Debentures to
Securityholders in exchange for 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 of the Debentures; and

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

         SECTION 9.3  Termination.

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

         SECTION 9.4  Liquidation.


<PAGE>   54



                                                                              47




         (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 or the making of reasonable provisions for the
payment 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 CUSIP Number of the Trust Securities;

                        (ii) state the Liquidation Date;

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

                        (iv) provide such information with respect to the
         mechanics by which Holders may exchange Trust Securities Certificates
         for Debentures, or if Section 9.4(d) applies 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 Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

         (c) Except where Section 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 or
traded, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on which
a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal will be made to Holders of Trust Securities
Certificates with respect to such Debentures) and (v) all rights of
Securityholders holding Trust Securities will


<PAGE>   55


                                                                              48



cease, except the right of such Securityholders to receive 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 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, the Preferred Securities shall have a priority over the 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 Person, except pursuant
to this Article IX. 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 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


<PAGE>   56


                                                                              49



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 Person or
permit any other Person 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 taxable as
a corporation or to be classified as other than a grantor trust for United
States federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

         SECTION 10.1  Limitation of Rights of Securityholders.

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

         SECTION 10.2  Liability of the Common Securityholder.

         The Holder of the Common Securities shall be liable for all of the
debts and obligations of the Trust (other than with respect to the Securities)
to the extent not satisfied out of the Trust's assets.

         SECTION 10.3   Amendment.

Securityholders, (i) to cure any ambiguity, correct or supplement any provision
herein which may be inconsistent with any other provision herein, or to make any
other provisions with respect to matters or questions arising under this Trust
Agreement, which shall not be inconsistent with the other provisions of this
Trust Agreement, or (ii) to modify, eliminate or add to any provisions of this
Trust Agreement to such extent as shall be necessary to ensure that the Trust
will be classified for United States federal income tax purposes as a grantor
trust and not be taxable as a corporation at all times that any Trust Securities
are outstanding or to ensure that the Trust will not be required to register as
an investment company under the 1940 Act; provided, however, that in the case of
clause (i) or clause (ii), such action shall not adversely affect in any
material respect the interests of any Securityholder, and any amendments of this
Trust Agreement shall become effective when notice thereof is given to the
Securityholders.

         (b) Except as provided in Section 10.3(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii)
receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's exemption from status of an
investment company under the 1940 Act or the Trust's status as a grantor trust
for United States federal income tax purposes and will not result in the Trust
being taxable as a Corporation for United States federal income tax purposes.

         (c) In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.3 or 6.6 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
paragraph (c) of this Section 10.3 may not be amended.

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

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

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

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

any way be affected or impaired thereby.

otherwise provided in Sections 4.1(a) and 4.2(d)), with the same force and

accrue thereon for the period after such date.

         SECTION 10.7  Successors.

         This Trust Agreement shall be binding upon and shall inure to the
benefit of any successor to the Depositor, the Trust or the Relevant Trustee,

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

Attention:  General Counsel's Office

                  Re:      First Tennessee Capital II
                           ____% Preferred Securities, Series __
                           CUSIP

Ladies and Gentlemen:

                  The purpose of this letter is to set forth certain matters
relating to the issuance and deposit with The Depository Trust Company ("DTC")
of the book-entry-only portion of the _____% Preferred Securities, Series _ (the
"Preferred Securities"), of First Tennessee Capital II, a statutory business
trust formed under the laws of the State of Delaware (the "Issuer"), governed by
the Amended and Restated Trust Agreement, dated as of _________ __, 199_,
between First Tennessee National Corporation ("the Corporation"), as Depositor,
The Bank of New York, as Property Trustee, and The Bank of New York (Delaware),
as Delaware Trustee. The payment of distributions on the Preferred Securities
and payments due upon liquidation of the Issuer or redemption of the Preferred
Securities, to the extent the Issuer has funds available for the payment
thereof, are guaranteed by the Corporation to the extent set forth in a
Guarantee Agreement, dated as of ________ __, 199_, between the Corporation and
The Bank of New York, as Guarantee Trustee with respect to the Preferred
Securities. The Corporation and the Issuer propose to sell the Preferred
Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement, dated as of _________ __, 199_, by and among the
Underwriters, the Issuer and the Corporation, and the Underwriters wish to take
delivery of the Preferred

                                       B-1

Securities through DTC. The Bank of New York is acting as transfer agent and
registrar with respect to the Preferred Securities (the "Transfer Agent and
Registrar").

                  To induce DTC to accept the Preferred Securities as eligible
for deposit at DTC, and to act in accordance with DTC's rules with respect to
the Preferred Securities, the Issuer and the Transfer Agent and Registrar make
the following representations to DTC:

                  1. Prior to the closing of the sale of the Preferred
Securities to the Underwriters on __________ __, 199_, there shall be deposited
with, or held by the Transfer Agent and Registrar as custodian for, DTC one or
more global certificates (individually and collectively, the "Global
Certificate") registered in the name of DTC's nominee, Cede & Co., representing
an aggregate of ________ 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 Issuer
         or its agent for registration of transfer, exchange, or payment, and
         any certificate issued is registered in the name of Cede & Co. or in
         such other name as is requested by an authorized representative of DTC
         (and any payment is made to Cede & Co. or to such other entity as is
         requested by an authorized representative of DTC), ANY TRANSFER,
         PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
         IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an
         interest herein.

                  2. The Amended and Restated Trust Agreement of the Issuer
provides for the voting by holders (with no provision for revocation of consents
or votes by subsequent holders) of the 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 Preferred Securities outstanding, the
Issuer or the Transfer Agent and Registrar shall send DTC a notice of such event
as soon as possible, but at least 5 business days prior to the effective date of
such event.

                  4. In the event of any distribution on, or an offering or
issuance of rights with respect to, the 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 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 Preferred
Securities or published by or on behalf of the Issuer (whether by mail or
publication, the "Publication Date"). Such notice

                                       B-2

<PAGE>   68



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

                                    New York, New York 10004-2695

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

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

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

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

                                       B-3

<PAGE>   69



receipt of such notice shall be confirmed by telephoning (212) 709-6884, or by
mail or any other means to:

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

                  7. All notices and payment advices sent to DTC shall contain
the CUSIP number or numbers of the Preferred Securities and the accompanying
designation of the Preferred Securities, which, as of the date of this letter,
is "First Tennessee Capital II, ____% Preferred Securities, Series _".

                  8. Distribution payments or other cash payments with respect
to the Preferred Securities shall be governed by DTC's current Principal and
Income Payments Rider, a copy of which is attached hereto as Annex I. For
purposes of this letter, the term "Agent" used in Annex I shall be deemed to
refer to The Bank of New York or any successor Property Trustee under the
Amended and Restated Trust Agreement.

                  9. DTC may 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 Preferred Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion: (a) may request the Issuer or the Transfer
Agent and Registrar to issue and countersign a new Global Certificate; or (b)
may make an appropriate notation on the Global Certificate indicating the date
and amount of such reduction.

                  11. DTC may discontinue its services as a securities
depositary with respect to the Preferred Securities at any time by giving
reasonable 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 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 book-entry settlement for the Preferred Securities, make
available one or more separate global certificates evidencing Preferred
Securities to any Participant having Preferred Securities credited to its DTC
account, or issue definitive 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

                                       B-4

<PAGE>   70



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 Preferred Securities shall be able to obtain definitive 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

         SECTION 3.1  Payment Account.

         (a) On or prior to the Closing Date, the Property Trustee shall

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

                            DISTRIBUTIONS; REDEMPTION

         SECTION 4.1  Distributions.

         (a) The Trust Securities represent undivided beneficial ownership
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 ________ __, 199_, 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] [semi-annually] [monthly] in

                                                                              16



        arrears on _________________, commencing on _______, 199_. 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 Distribution
         period shall be computed on the basis of a 30-day year of twelve 30-day
         months. The amount of Distributions for any partial Distribution 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.

         (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 15 days prior to the relevant
Distribution Date (whether or not such record date is a Business Day).

         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 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;



<PAGE>   24


                                                                              17



                        (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;

                         (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; and

                        (vi) if the Preferred Securities are no longer in
         book-entry-only form, the place and address where the Holders shall
         surrender their Preferred Securities Certificates.

         (c) The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption or payment at stated maturity of 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, New York City time, on the
Redemption Date, subject to Section 4.2(c), the Property Trustee will, so long
as the Preferred Securities are in book- entry-only form, 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
instructions and authority to pay the Redemption Price to the Holders thereof.
If the Preferred Securities are no longer in book-entry-only 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 Securities
Register for the Trust Securities on the relevant record dates for the related
Distribution Dates. If notice of redemption shall have been given and funds
deposited as required, then upon the date of such deposit, all rights of
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
thereon, and such Trust Securities will cease to be outstanding. In the event
that any date on which any Redemption Price is payable is not a Business Day,
then payment of the Redemption Price payable on such date will be made on the
next succeeding day that is a Business Day (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


<PAGE>   25


                                                                              18



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 as the Property Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to $_____ or an
integral multiple of $_____ in excess thereof) of the Liquidation Amount of
Preferred Securities of a denomination larger than $_____. 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


<PAGE>   26


                                                                              19



Securities for all Distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all Outstanding Preferred Securities then called for redemption, shall
have been made or provided for, and all funds immediately available to the
Property Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

         (b) In the case of the occurrence of any Event of Default resulting
from 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.

         SECTION 4.4  Payment Procedures.

         Payments of Distributions (including Additional Amounts, if applicable)
in respect of the Preferred Securities shall be made by wire transfer, direct
deposit or 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 in writing 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, if any, and
the information required to be provided by the Trust 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 Issuer Trust.

         Upon receipt under the Debentures of Additional Sums, the Property
Trustee shall promptly pay any taxes, duties or governmental charges of
whatsoever nature (other than withholding taxes) imposed on the 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
shall be reduced by the amount of any corresponding payment such Holder (or an
Owner with respect to the Holder's Preferred Securities) has directly received
pursuant to Section 5.8 of the Indenture or Section 5.14 of this Trust
Agreement.

         Upon the creation of the Trust and the contribution by the Depositor

or its agent and (ii) authenticated by the Property Trustee by manual or
facsimile signature of an authorized signatory thereof and, if executed by such
authorized signatory of the Property Trustee by facsimile, countersigned by a

signatures of individuals who were, at the time when such signatures shall have
been affixed, authorized to sign on behalf of the Trust or the Property Trustee
or, if executed on behalf of the Trust or the Property Trustee by facsimile,
countersigned by a transfer agent or its agent, shall be validly issued and
entitled to the benefits of this Trust Agreement, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
delivery of such Trust Securities Certificates or did not hold such offices at
the date of delivery of such Trust Securities Certificates. A transferee of a
Trust Securities Certificate shall become a Securityholder, and shall be
entitled to the rights and subject to the obligations of a Securityholder
hereunder, upon due


<PAGE>   28


                                                                              21



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.

         On the Closing Date, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to or
upon the written order of the Depositor, signed by its chairman of the board,
its chief executive officer, its president, any executive vice president, any
senior 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
transfer agent and registrar designated by the Depositor (the "Securities
Registrar"), subject to such reasonable regulations as it may prescribe, shall
provide for the registration of 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 on behalf of the Trust

certificate shall be countersigned by a transfer agent or its agent) 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
during a period beginning at the opening of business 15 days before the day of
selection for such redemption.

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

                                                                              22



disposed of by an Administrative Trustee or the Securities Registrar in
accordance with such Person's customary practice.

         No service charge shall be made for any registration of transfer or
exchange of 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 by manual or facsimile signature and, if executed on behalf
of the Trust by facsimile signature, such certificate shall be countersigned by
a transfer agent, 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 Trust Property, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

         SECTION 5.6  Persons Deemed Securityholders.

         The Trustees or the Securities Registrar shall treat the Person in
whose name any Trust Securities 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.

         Each Holder 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.



<PAGE>   30


                                                                              23



         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 Bank of New York, 101
Barclay Street, Floor 21 West, New York, New York 10286, Attn: Corporate Trust
Administration, as its principal corporate trust office for such purposes. The
Administrative Trustees shall give prompt written notice to the Depositor, the
Property Trustee 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 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 Bank, and any co-paying agent chosen by the Bank, 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 Bank 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 resignation or 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, and any
Paying Agent shall be bound by the requirements with respect to paying agents of
securities issued pursuant to the Trust Indenture Act. 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.

         On the Closing Date, the Depositor shall acquire and retain beneficial
and record ownership of the Common Securities. To the fullest extent permitted
by law, other than a


<PAGE>   31


                                                                              24



transfer in connection with a consolidation or merger of the Depositor into
another Person, or any conveyance, transfer or lease by the Depositor of its
properties and assets substantially as an entirety to any Person, pursuant to
Section 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 TO ANY PERSON".

         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 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 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 and the giving of instructions or
         directions to Owners of Preferred Securities evidenced by Book-Entry
         Preferred Securities Certificates) as the sole Holder of Preferred
         Securities evidenced by 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.

         (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.

         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
Administrative Trustees in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interest of the Owners of
Preferred Securities Certificates, then the Administrative Trustees shall notify
the other Trustees and the Clearing Agency, and the Clearing Agency, in
accordance with its customary rules and procedures, shall notify all Clearing
Agency Participants for whom it holds Preferred Securities 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 Administrative Trustees 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 which, if executed on behalf of the Trust by facsimile,
shall be countersigned by a transfer agent or its agent. Neither the Securities
Registrar nor the Trustees shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such instructions. Upon the issuance of Definitive Preferred Securities
Certificates, the Trustees shall recognize the Holders of the Definitive
Preferred Securities Certificates as Securityholders. The Definitive Preferred
Securities Certificates shall be typewritten, printed, lithographed or engraved
or may be produced in any other manner as is reasonably acceptable to the
Administrative Trustees that meets the requirements of any stock exchange or
automated quotation system on which the Preferred Securities are then listed or
approved for trading, as evidenced by the execution thereof by the
Administrative Trustees or any one of them.

         SECTION 5.14  Rights of Securityholders.



<PAGE>   33


                                                                              26



         (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 ownership 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 Preferred Securities, in
their capacities as such, shall be entitled to the same limitation of personal
liability extended to stockholders of private corporations for profit organized
under the General Corporation Law of the State of Delaware.

         (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 as set forth in the Indenture, provided that
the payment of principal, premium 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



<PAGE>   34


                                                                              27



                        (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, premium or interest (unless 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
annulled as provided in Section 5.3 of the Indenture and the Company has paid or
deposited with the Debenture Trustee a sum sufficient to pay all overdue
installments of interest (including any Additional Interest (as defined in the
Indenture)) on the Debentures, 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 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) 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 of Outstanding Preferred Securities 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


<PAGE>   35


                                                                              28



Holder of the principal amount of or premium 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.

         SECTION 5.15  CUSIP Numbers.

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



                                   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 10.3
and in the Indenture and as otherwise required by law, no Holder of Preferred
Securities shall have any right to vote or in any manner otherwise control the
administration, operation and management of the Trust or the obligations of the
parties hereto, nor shall anything herein set forth, or contained in the terms
of the Trust Securities Certificates, be construed so as to constitute the
Securityholders from time to time as partners or members of an association.

         (b) So long as any Debentures are held by the Property Trustee, 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 waiveable 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


<PAGE>   36


                                                                              29



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 Administrative 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 or cause the Trust to be taxable as a corporation 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 or to be taxable as a corporation for United
States federal income tax purposes.

         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 10.9 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 the Preferred
Securityholders 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.

         Preferred Securityholders 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 Preferred Securityholders.



<PAGE>   37


                                                                              30



         If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding at
least a majority of the Outstanding Preferred Securities (based upon their
Liquidation Amount) held by holders of record of Outstanding Preferred
Securities 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 $_____ 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 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 at least a majority of all
Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
vote in respect of such action (or such larger proportion thereof as shall be
required by any express provision of this Trust Agreement) shall consent to the
action in writing.

         SECTION 6.7  Record Date for Voting and Other Purposes.

         For the purposes of determining the Securityholders who are entitled to
notice of and to vote at any meeting or by written consent, or to participate in
any Distribution on the Trust Securities in respect of which a record date is
not otherwise provided for in this Trust Agreement, or for the purpose of any
other action, the Administrative 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


<PAGE>   38


                                                                              31



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 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


<PAGE>   39


                                                                              32



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.

         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.

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

the Trust (or the Trustees on behalf of the Trust) under the laws of the State
of Delaware or any political subdivision thereof in connection with the
execution, delivery and performance by the Property Trustee or the Delaware
Trustee, as the case may be, of this Trust Agreement.

                                  ARTICLE VIII

                                  THE TRUSTEES

         SECTION 8.1  Certain Duties and Responsibilities.

         (a) The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee, by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
them. Whether or not therein expressly so provided, every provision of this
Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustees shall be subject to the provisions of this
Section. Nothing in this Trust Agreement shall be construed to release 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;



<PAGE>   42


                                                                              35



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

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

                        (iv) the Property Trustee shall not be liable for any
         interest on any money received by it except as it may otherwise agree
         in writing 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.

         Within ten 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 10.9, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived.

         Within five Business Days after the receipt of notice of the
Depositor's exercise of its right to defer the payment of interest on the
Debentures pursuant to the Indenture, the Administrative Trustee shall transmit,
in the manner and to the extent provided in Section 10.9, notice of such
exercise to the Securityholders and the Property Trustee, unless such exercise
shall have been revoked.

         SECTION 8.3  Certain Rights of Property Trustee.

         Subject to the provisions of Section 8.1:

         (a) the Property Trustee may rely and shall be protected in acting or
refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate,


<PAGE>   43


                                                                              36



statement, instrument, opinion, report, notice, request, consent, order,
appraisal, bond, debenture, note, other evidence of indebtedness or other paper
or document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

         (b) if (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action or
(ii) in construing any of the provisions of this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to which
the 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 reregistration thereof;

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

         (g) the Property Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the


<PAGE>   44


                                                                              37



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 written instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request written instructions from the Holders of the Trust
Securities which written 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 written instructions are
received, and (iii) shall be protected in acting in accordance with such written
instructions; and

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

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

         SECTION 8.4  Not Responsible for Recitals or Issuance of Securities.

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


<PAGE>   45


                                                                              38




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

         SECTION 8.6  Compensation; Indemnity; Fees.

         The Holder of the Common Securities shall:

         (a) pay to the Trustees from time to time such compensation as shall be
agreed in writing with the Holder of the Common Securities 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);

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

         (c) to the fullest extent permitted by applicable law, 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 and all
loss, damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by this Trust Agreement, except
that no Indemnified Person shall be entitled to be indemnified in respect of any
loss, damage or claim incurred by such Indemnified Person by reason of
negligence or willful misconduct with respect to such acts or omissions. When
the Property Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(4) or Section 5.1(5) of the Indenture,
the expenses (including the reasonable charges and expenses of its counsel) and
the compensation for the services are intended to constitute expenses of
administration under any applicable federal or state bankruptcy, insolvency or
other similar law.

         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.

                                                                              39



         The Depositor and any Trustee (in the case of the Property Trustee,
subject to Section 8.8 hereof) 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 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.

                                                                              40




         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 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.



<PAGE>   48


                                                                              41



         (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 Common
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 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). An Administrative Trustee may
be removed by the Common Securityholder at any time. 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 such removal, the
Relevant Trustee may petition, at the expense of the Trust, any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.



<PAGE>   49


                                                                              42



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

         Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative 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 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


<PAGE>   50

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

Trustee such retiring Relevant Trustee shall, upon payment of its charges, duly
assign, transfer and deliver to such successor Relevant Trustee all Trust
Property, all proceeds thereof and money held by such retiring Relevant Trustee
hereunder with respect to the Trust Securities and the Trust.

         Upon written 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 preceding paragraph.

         No successor Relevant Trustee shall accept its appointment unless at
the time of such acceptance such successor Relevant Trustee shall be qualified

         Any Person into which the Property Trustee or the Delaware Trustee may
be merged or converted or with which it may be consolidated, or any Person
resulting from any merger, conversion or consolidation to which such Relevant

                                                                              44



         (a) to file and prove a claim for the whole amount of any Distributions

Trustee to authorize or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or compensation affecting
the Trust Securities or the rights of any Holder thereof or to authorize the
Property Trustee to vote in respect of the claim of any Holder in any such
proceeding.

         SECTION 8.14  Reports by Property Trustee.

         (a) The Property Trustee shall transmit to Securityholders such reports
concerning the Property Trustee and its actions under this Trust Agreement as
may be required pursuant to the Trust Indenture Act at the times and in the
manner provided pursuant thereto. If required by Section 313(a) of the Trust
Indenture Act, the Property Trustee shall, within sixty days after each May 15
following the date of this Trust Agreement deliver to Securityholders a brief
report, dated as of such May 15, which complies with the provisions of such
Section 313(a).

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

         SECTION 8.15  Reports to the Property Trustee.

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

                                                                              45



such shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the
Trust's compliance with any of its covenants hereunder (as to which the Property
Trustee is entitled to rely exclusively on Officers' Certificates).

         SECTION 8.16  Evidence of Compliance with Conditions Precedent.

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

Officers' Certificate.

         SECTION 8.17  Number of Trustees.

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

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

         (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to dissolve, terminate or 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
with applicable law, delegate to any other natural person over the age of 21 his
or her power for the purpose of executing any documents contemplated in Section
2.7(a), including any registration statement or amendment thereto filed with the
Commission, or making any other governmental filing; and

         (b) The Administrative Trustees shall have power to delegate from time
to time to such of their number or to the Depositor the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the Administrative Trustees or

                                                                              46



otherwise as the Administrative Trustees may deem expedient, to the extent such
delegation is not prohibited by applicable law or contrary to the provisions of
this Trust Agreement, as set forth herein.


                                   ARTICLE IX

                       TERMINATION, LIQUIDATION AND MERGER

         SECTION 9.1  Termination Upon Expiration Date.

         Unless earlier terminated, the Trust shall automatically terminate on
____________, 20__ (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 Holder of the Common Securities;

         (b) the written direction to the Property Trustee from the Depositor at
any time to terminate the Trust and, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, distribute Debentures to
Securityholders in exchange for 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 of the Debentures; and

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

         SECTION 9.3  Termination.

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


         SECTION 9.4  Liquidation.


<PAGE>   54


                                                                              47




         (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 or the making of reasonable provisions for the
payment 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 CUSIP Number of the Trust Securities;

                        (ii)   state the Liquidation Date;

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

                        (iv) provide such information with respect to the
         mechanics by which Holders may exchange Trust Securities Certificates
         for Debentures, or if Section 9.4(d) applies 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 Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

         (c) Except where Section 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 or
traded, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on which
a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so surrendered,
no payments of interest or principal will be made to Holders of Trust Securities
Certificates with respect to such Debentures) and (v) all rights of
Securityholders holding Trust Securities will


<PAGE>   55


                                                                              48



cease, except the right of such Securityholders to receive 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 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, the Preferred Securities shall have a priority over the 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 Person, except pursuant
to this Article IX. 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 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


<PAGE>   56


                                                                              49



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 Person or
permit any other Person 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 taxable as
a corporation or to be classified as other than a grantor trust for United
States federal income tax purposes.


                                    ARTICLE X

                            MISCELLANEOUS PROVISIONS

         SECTION 10.1  Limitation of Rights of Securityholders.

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

         SECTION 10.2  Liability of the Common Securityholder.

         The Holder of the Common Securities shall be liable for all of the
debts and obligations of the Trust (other than with respect to the Securities)
to the extent not satisfied out of the Trust's assets.

         SECTION 10.3   Amendment.

         (a) This Trust Agreement may be amended from time to time by the
Property Trustee, the Administrative Trustees and the Depositor, without the

Securityholders, (i) to cure any ambiguity, correct or supplement any provision
herein which may be inconsistent with any other provision herein, or to make any
other provisions with respect to matters or questions arising under this Trust
Agreement, which shall not be inconsistent with the other provisions of this
Trust Agreement, or (ii) to modify, eliminate or add to any provisions of this
Trust Agreement to such extent as shall be necessary to ensure that the Trust
will be classified for United States federal income tax purposes as a grantor
trust and not be taxable as a corporation at all times that any Trust Securities
are outstanding or to ensure that the Trust will not be required to register as
an investment company under the 1940 Act; provided, however, that in the case of
clause (i) or clause (ii), such action shall not adversely affect in any
material respect the interests of any Securityholder, and any amendments of this
Trust Agreement shall become effective when notice thereof is given to the
Securityholders.

         (b) Except as provided in Section 10.3(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii)
receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's exemption from status of an
investment company under the 1940 Act or the Trust's status as a grantor trust
for United States federal income tax purposes and will not result in the Trust
being taxable as a corporation for United States federal income tax purposes.

         (c) In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.3 or 6.6 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
paragraph (c) of this Section 10.3 may not be amended.

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

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

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

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

any way be affected or impaired thereby.

         SECTION 10.6  Payments Due on Non-Business Day.

otherwise provided in Sections 4.1(a) and 4.2(d)), with the same force and

accrue thereon for the period after such date.

         SECTION 10.7  Successors.

         This Trust Agreement shall be binding upon and shall inure to the
benefit of any successor to the Depositor, the Trust or the Relevant Trustee,

         Each of the Trustees and the Depositor agree for the benefit of the
Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Depositor takes action in violation of this Section 10.10, the
Property Trustee agrees, for the benefit of Securityholders, that at the expense
of the Depositor, it shall file an answer with the bankruptcy court or otherwise
properly contest the filing of such petition by the Depositor against the Trust
or the commencement of such action and raise the defense that the Depositor has
agreed in writing not to take such action and should be stopped and precluded
therefrom and such other defenses, if any, as counsel for the Trustee or the
Trust may assert. The provisions of this Section 10.10 shall survive the
termination of this Trust Agreement.

         (a) This Trust Agreement is subject to the provisions of the Trust

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

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

         SECTION 10.12 Acceptance of Terms of Trust Agreement, Guarantee and
Indenture.

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

                           ____% Preferred Securities, Series __
                           CUSIP

Ladies and Gentlemen:

                  The purpose of this letter is to set forth certain matters
relating to the issuance and deposit with The Depository Trust Company ("DTC")
of the book-entry-only portion of the _____% Preferred Securities, Series _ (the
"Preferred Securities"), of First Tennessee Capital III, a statutory business
trust formed under the laws of the State of Delaware (the "Issuer"), governed by
the Amended and Restated Trust Agreement, dated as of _________ __, 199_,
between First Tennessee National Corporation ("the Corporation"), as Depositor,
The Bank of New York, as Property Trustee, and The Bank of New York (Delaware),
as Delaware Trustee. The payment of distributions on the Preferred Securities
and payments due upon liquidation of the Issuer or redemption of the Preferred
Securities, to the extent the Issuer has funds available for the payment
thereof, are guaranteed by the Corporation to the extent set forth in a
Guarantee Agreement, dated as of ________ __, 199_, between the Corporation and
The Bank of New York, as Guarantee Trustee with respect to the Preferred
Securities. The Corporation and the Issuer propose to sell the Preferred
Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement, dated as of _________ __, 199_, by and among the
Underwriters, the Issuer and the Corporation, and the Underwriters wish to take
delivery of the Preferred

                                       B-1

Securities through DTC. The Bank of New York is acting as transfer agent and
registrar with respect to the Preferred Securities (the "Transfer Agent and
Registrar").

                  To induce DTC to accept the Preferred Securities as eligible
for deposit at DTC, and to act in accordance with DTC's rules with respect to
the Preferred Securities, the Issuer and the Transfer Agent and Registrar make
the following representations to DTC:

                  1. Prior to the closing of the sale of the Preferred
Securities to the Underwriters on __________ __, 199_, there shall be deposited
with, or held by the Transfer Agent and Registrar as custodian for, DTC one or
more global certificates (individually and collectively, the "Global
Certificate") registered in the name of DTC's nominee, Cede & Co., representing
an aggregate of ________ 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 Issuer
         or its agent for registration of transfer, exchange, or payment, and
         any certificate issued is registered in the name of Cede & Co. or in
         such other name as is requested by an authorized representative of DTC
         (and any payment is made to Cede & Co. or to such other entity as is
         requested by an authorized representative of DTC), ANY TRANSFER,
         PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
         IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an
         interest herein.

                  2. The Amended and Restated Trust Agreement of the Issuer
provides for the voting by holders (with no provision for revocation of consents
or votes by subsequent holders) of the 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 Preferred Securities outstanding, the
Issuer or the Transfer Agent and Registrar shall send DTC a notice of such event
as soon as possible, but at least 5 business days prior to the effective date of
such event.

                  4. In the event of any distribution on, or an offering or
issuance of rights with respect to, the 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 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 Preferred
Securities or published by or on behalf of the Issuer (whether by mail or
publication, the "Publication Date"). Such notice

                                       B-2

<PAGE>   68



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

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

                  5. In the event of a redemption by the Issuer of the Preferred
Securities, notice specifying the terms of the redemption and the Publication
Date of such notice shall be sent by the Issuer or the Transfer Agent and
Registrar to DTC not less than 30 calendar days prior to such event by a secure

                  7. All notices and payment advices sent to DTC shall contain
the CUSIP number or numbers of the Preferred Securities and the accompanying
designation of the Preferred Securities, which, as of the date of this letter,
is "First Tennessee Capital III, ____% Preferred Securities, Series _".

                  8. Distribution payments or other cash payments with respect
to the Preferred Securities shall be governed by DTC's current Principal and
Income Payments Rider, a copy of which is attached hereto as Annex I. For
purposes of this letter, the term "Agent" used in Annex I shall be deemed to
refer to The Bank of New York or any successor Property Trustee under the
Amended and Restated Trust Agreement.

                  9. DTC may 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 Preferred Securities outstanding evidenced by the Global
Certificate, DTC, in its discretion: (a) may request the Issuer or the Transfer
Agent and Registrar to issue and countersign a new Global Certificate; or (b)
may make an appropriate notation on the Global Certificate indicating the date
and amount of such reduction.

                  11. DTC may discontinue its services as a securities
depositary with respect to the Preferred Securities at any time by giving
reasonable 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 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 book-entry settlement for the Preferred Securities, make
available one or more separate global certificates evidencing Preferred
Securities to any Participant having Preferred Securities credited to its DTC
account, or issue definitive 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

                                       B-4

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 Preferred Securities shall be able to obtain definitive 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.

         Commission and the execution on behalf of the Trust of a registration
         statement on the appropriate form in relation to the Preferred
         Securities, including any amendments thereto;

                           (ii) the determination of the states in which to take
         appropriate action to qualify or register for sale all or part of the
         Preferred Securities and the determination of any and all such acts,
         other than actions which must be taken by or on behalf of the Trust,
         and the advice to the Trustees of actions they must take on behalf of

         Depositor deems necessary or advisable in order to comply with the

         upon notice of issuance of any Preferred Securities and filing with
         such exchange or self-regulatory organization such notifications and
         documents as may be necessary from time to time to maintain such
         listing;

                           (iv) the negotiation of the terms of, and the
         execution and delivery of, the Underwriting Agreement providing for
         the sale of the Preferred Securities; and

         desirable to carry out any of the foregoing activities.

         (d) Notwithstanding anything herein to the contrary, the Administrative

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 be taxable as a
corporation 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.

                                                                              15




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

         SECTION 2.9  Title to Trust Property.

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,

                           DISTRIBUTIONS; REDEMPTION

         SECTION 4.1  Distributions.

         (a) The Trust Securities represent undivided beneficial ownership
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 ________ __, 199_, 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] [semi-annually] [monthly] in

                                                                              16



        arrears on _________________, commencing on _______, 199_. 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
         Distribution period shall be computed on the basis of a 30-day year of
         twelve 30-day months.  The amount of Distributions for any partial
         Distribution 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.

         (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 15 days prior to the relevant
Distribution Date (whether or not such record date is a Business Day).

         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 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;
<PAGE>   24
                                                                              17




                           (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;

                            (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; and

                           (vi)    if the Preferred Securities are no longer in
         book-entry-only form, the place and address where the Holders shall
         surrender their Preferred Securities Certificates.

         (c) The Trust Securities redeemed on each Redemption Date shall be
redeemed at the Redemption Price with the proceeds from the contemporaneous
redemption or payment at stated maturity of 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, New York City time, on the
Redemption Date, subject to Section 4.2(c), the Property Trustee will, so long
as the Preferred Securities are in book-entry-only form, 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
instructions and authority to pay the Redemption Price to the Holders thereof.
If the Preferred Securities are no longer in book-entry-only 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
Securities Register for the Trust Securities on the relevant record dates for
the related Distribution Dates. If notice of redemption shall have been given
and funds deposited as required, then upon the date of such deposit, all rights
of 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 thereon, and such Trust Securities will cease to be outstanding. In
the event that any date on which any Redemption Price is payable is not a
Business Day, then payment of the Redemption Price payable on such date will be
made on the next succeeding day that is a Business Day (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
<PAGE>   25
                                                                              18



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 as the Property Trustee shall deem fair and appropriate and which may
provide for the selection for redemption of portions (equal to $_____ or an
integral multiple of $_____ in excess thereof) of the Liquidation Amount of
Preferred Securities of a denomination larger than $_____. 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
<PAGE>   26
                                                                              19



Securities for all Distribution periods terminating on or prior thereto, or in
the case of payment of the Redemption Price the full amount of such Redemption
Price on all Outstanding Preferred Securities then called for redemption, shall
have been made or provided for, and all funds immediately available to the
Property Trustee shall first be applied to the payment in full in cash of all
Distributions (including Additional Amounts, if applicable) on, or the
Redemption Price of, Preferred Securities then due and payable.

         (b) In the case of the occurrence of any Event of Default resulting
from 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.

         SECTION 4.4  Payment Procedures.

         Payments of Distributions (including Additional Amounts, if
applicable) in respect of the Preferred Securities shall be made by wire
transfer, direct deposit or check mailed to the address of the Person entitled
thereto as such address shall appear on the Securities Register or, if the

         Upon the creation of the Trust and the contribution by the Depositor

any time during which no Trust Securities are outstanding, the Depositor shall
be the sole beneficial owner of the Trust.

         SECTION 5.2  The Trust Securities Certificates.

         The Preferred Securities Certificates shall be issued in minimum
denominations of $_____ Liquidation Amount and integral multiples of $_____ in
excess thereof, and the Common Securities Certificates shall be issued in

or its agent and (ii) authenticated by the Property Trustee by manual or
facsimile signature of an authorized signatory thereof and, if executed by such
authorized signatory of the Property Trustee by facsimile, countersigned by a

signatures of individuals who were, at the time when such signatures shall have
been affixed, authorized to sign on behalf of the Trust or the Property Trustee
or, if executed on behalf of the Trust or the Property Trustee by facsimile,
countersigned by a transfer agent or its agent,  shall be validly issued and
entitled to the benefits of this Trust Agreement, notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
delivery of such Trust Securities Certificates or did not hold such offices at
the date of delivery of such Trust Securities Certificates. A transferee of a
Trust Securities Certificate shall become a Securityholder, and shall be
entitled to the rights and subject to the obligations of a Securityholder
hereunder, upon due
<PAGE>   28
                                                                              21



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.

         On the Closing Date, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 2.4 and 2.5, to be executed on behalf of the Trust and delivered to or
upon the written order of the Depositor, signed by its chairman of the board,
its chief executive officer, its president, any executive vice president, any
senior 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
transfer agent and registrar designated by the Depositor (the "Securities
Registrar"), subject to such reasonable regulations as it may prescribe, shall
provide for the registration of 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 on behalf of
the Trust (and if executed on behalf of the Trust by a facsimile signature,
such certificate shall be countersigned by a transfer agent or its agent) 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 during a period beginning at the opening of business 15 days before
the day of selection for such redemption.

         At the option of a Holder, Preferred Securities Certificates may be
exchanged for other Preferred Securities Certificates in authorized
denominations of the same class and of a like aggregate Liquidation Amount upon
surrender of the Preferred Securities Certificates to be exchanged at the
office or agency maintained pursuant to Section 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 cancelled and subsequently
<PAGE>   29
                                                                              22



disposed of by an Administrative Trustee or the Securities Registrar in
accordance with such Person's customary practice.

         No service charge shall be made for any registration of transfer or
exchange of 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 by manual or facsimile signature and, if executed on behalf
of the Trust by facsimile signature, such certificate shall be countersigned by
a transfer agent, 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 Trust Property, as if
originally issued, whether or not the lost, stolen or destroyed Trust
Securities Certificate shall be found at any time.

         SECTION 5.6  Persons Deemed Securityholders.

         The Trustees or the Securities Registrar shall treat the Person in
whose name any Trust Securities 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.

         Each Holder 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.
<PAGE>   30
                                                                              23



         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 Bank of New York, 101
Barclay Street, Floor 21 West, New York, New York 10286, Attn: Corporate Trust
Administration, as its principal corporate trust office for such purposes. The
Administrative Trustees shall give prompt written notice to the Depositor, the
Property Trustee 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 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 Bank, and any co-paying agent chosen by the Bank,
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 Bank 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 resignation or 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, and any Paying Agent shall be bound by the
requirements with respect to paying agents of securities issued pursuant to the
Trust Indenture Act.  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.

         On the Closing Date, the Depositor shall acquire and retain beneficial
and record ownership of the Common Securities. To the fullest extent permitted
by law, other than a
<PAGE>   31
                                                                              24



transfer in connection with a consolidation or merger of the Depositor into
another Person, or any conveyance, transfer or lease by the Depositor of its
properties and assets substantially as an entirety to any Person, pursuant to
Section 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 TO ANY PERSON".

         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 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 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 and the giving of instructions or
         directions to Owners of Preferred Securities evidenced by Book-Entry
         Preferred Securities Certificates) as the sole Holder of Preferred
         Securities evidenced by 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.

                                                                              25



         (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.

         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
Administrative Trustees in writing that the continuation of a book-entry system
through the Clearing Agency is no longer in the best interest of the Owners of
Preferred Securities Certificates, then the Administrative Trustees shall
notify the other Trustees and the Clearing Agency, and the Clearing Agency, in
accordance with its customary rules and procedures, shall notify all Clearing
Agency Participants for whom it holds Preferred Securities 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 Administrative Trustees 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 which, if executed on behalf of
the Trust by facsimile, shall be countersigned by a transfer agent or its
agent. Neither the Securities Registrar nor the Trustees shall be liable for
any delay in delivery of such instructions and may conclusively rely on, and
shall be protected in relying on, such instructions. Upon the issuance of
Definitive Preferred Securities Certificates, the Trustees shall recognize the
Holders of the Definitive Preferred Securities Certificates as Securityholders.
The Definitive Preferred Securities Certificates shall be typewritten, printed,
lithographed or engraved or may be produced in any other manner as is
reasonably acceptable to the Administrative Trustees that meets the
requirements of any stock exchange or automated quotation system on which the
Preferred Securities are then listed or approved for trading, as evidenced by
the execution thereof by the Administrative Trustees or any one of them.

         SECTION 5.14  Rights of Securityholders.
<PAGE>   33
                                                                              26



         (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 ownership 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 Preferred
Securities, in their capacities as such, shall be entitled to the same
limitation of personal liability extended to stockholders of private
corporations for profit organized under the General Corporation Law of the
State of Delaware.

         (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 as set forth in the Indenture, provided that
the payment of principal, premium 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
<PAGE>   34
                                                                              27



                         (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, premium or interest (unless 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
annulled as provided in Section 5.3 of the Indenture and the Company has paid
or deposited with the Debenture Trustee a sum sufficient to pay all overdue
installments of interest (including any Additional Interest (as defined in the
Indenture)) on the Debentures, 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 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) 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 of Outstanding Preferred
Securities 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
<PAGE>   35
                                                                              28



Holder of the principal amount of or premium 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.

         SECTION 5.15  CUSIP Numbers.

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

         SECTION 6.1  Limitations on Voting Rights.

         (a) Except as provided in this Section, in Sections 5.14, 8.10 and
10.3 and in the Indenture and as otherwise required by law, no Holder of
Preferred Securities shall have any right to vote or in any manner otherwise
control the administration, operation and management of the Trust or the
obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Trust Securities Certificates, be construed so as
to constitute the Securityholders from time to time as partners or members of
an association.

         (b) So long as any Debentures are held by the Property Trustee, 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 waiveable 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
<PAGE>   36
                                                                              29



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 Administrative 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 or cause the Trust to be taxable as a corporation 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 or to be taxable as a corporation for United
States federal income tax purposes.

         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 10.9 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 the Preferred
Securityholders 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.

         Preferred Securityholders 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 Preferred
Securityholders.
<PAGE>   37
                                                                              30



         If a quorum is present at a meeting, an affirmative vote by the
Preferred Securityholders of record present, in person or by proxy, holding at
least a majority of the Outstanding Preferred Securities (based upon their
Liquidation Amount) held by holders of record of Outstanding Preferred
Securities 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 $_____ 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 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 at least a majority of all
Outstanding Trust Securities (based upon their Liquidation Amount) entitled to
vote in respect of such action (or such larger proportion thereof as shall be
required by any express provision of this Trust Agreement) shall consent to the
action in writing.

         SECTION 6.7  Record Date for Voting and Other Purposes.

         For the purposes of determining the Securityholders who are entitled
to notice of and to vote at any meeting or by written consent, or to
participate in any Distribution on the Trust Securities in respect of which a
record date is not otherwise provided for in this Trust Agreement, or for the
purpose of any other action, the Administrative 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
<PAGE>   38
                                                                              31



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 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
<PAGE>   39
                                                                              32



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.

         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.

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

         SECTION 7.2  Representations and Warranties of Depositor.

                                  ARTICLE VIII

                                  THE TRUSTEES

         SECTION 8.1  Certain Duties and Responsibilities.

         (a) The duties and responsibilities of the Trustees shall be as
provided by this Trust Agreement and, in the case of the Property Trustee, by
the Trust Indenture Act. Notwithstanding the foregoing, no provision of this
Trust Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
them. Whether or not therein expressly so provided, every provision of this
Trust Agreement relating to the conduct or affecting the liability of or
affording protection to the Trustees shall be subject to the provisions of this
Section. Nothing in this Trust Agreement shall be construed to release 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;
<PAGE>   42
                                                                              35



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

                          (iii)    the Property Trustee's sole duty with
         respect to the custody, safekeeping 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 in writing 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.

         Within ten 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 10.9, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived.

         Within five Business Days after the receipt of notice of the
Depositor's exercise of its right to defer the payment of interest on the
Debentures pursuant to the Indenture, the Administrative Trustee shall
transmit, in the manner and to the extent provided in Section 10.9, notice of
such exercise to the Securityholders and the Property Trustee, unless such
exercise shall have been revoked.

         SECTION 8.3  Certain Rights of Property Trustee.

         Subject to the provisions of Section 8.1:

         (a) the Property Trustee may rely and shall be protected in acting or
refraining from acting in good faith upon any resolution, Opinion of Counsel,
certificate, written representation of a Holder or transferee, certificate of
auditors or any other certificate,
<PAGE>   43
                                                                              36



statement, instrument, opinion, report, notice, request, consent, order,
appraisal, bond, debenture, note, other evidence of indebtedness or other paper
or document believed by it to be genuine and to have been signed or presented
by the proper party or parties;

         (b) if (i) in performing its duties under this Trust Agreement the
Property Trustee is required to decide between alternative courses of action or
(ii) in construing any of the provisions of this Trust Agreement the Property
Trustee finds the same ambiguous or inconsistent with any other provisions
contained herein or (iii) the Property Trustee is unsure of the application of
any provision of this Trust Agreement, then, except as to any matter as to
which the 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 reregistration thereof;

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

         (g) the Property Trustee shall be under no obligation to exercise any
of the rights or powers vested in it by this Trust Agreement at the request or
direction of any of the
<PAGE>   44
                                                                              37



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 written instructions with
respect to enforcing any remedy or right or taking any other action hereunder
the Property Trustee (i) may request written instructions from the Holders of
the Trust Securities which written 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 written
instructions are received, and (iii) shall be protected in acting in accordance
with such written instructions; and

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

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

         SECTION 8.4  Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Trust Securities Certificates
shall be taken as the statements of the 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.
<PAGE>   45
                                                                              38




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

         SECTION 8.6  Compensation; Indemnity; Fees.

         The Holder of the Common Securities shall:

         (a) pay to the Trustees from time to time such compensation as shall
be agreed in writing with the Holder of the Common Securities 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);

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

         (c) to the fullest extent permitted by applicable law, 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 and all
loss, damage, liability, tax, penalty, expense or claim of any kind or nature
whatsoever incurred by such Indemnified Person by reason of the creation,
operation or termination of the Trust or any act or omission performed or
omitted by such Indemnified Person in good faith on behalf of the Trust and in
a manner such Indemnified Person reasonably believed to be within the scope of
authority conferred on such Indemnified Person by this Trust Agreement, except
that no Indemnified Person shall be entitled to be indemnified in respect of
any loss, damage or claim incurred by such Indemnified Person by reason of
negligence or willful misconduct with respect to such acts or omissions.  When
the Property Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 5.1(4) or Section 5.1(5) of the
Indenture, the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law.

         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 (in the case of the Property Trustee,
subject to Section 8.8 hereof) 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 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.

                                                                              40




         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 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.
<PAGE>   48
                                                                              41



         (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 Common
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 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). An Administrative Trustee may
be removed by the Common Securityholder at any time. 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 such removal, the
Relevant Trustee may petition, at the expense of the Trust, any court of
competent jurisdiction for the appointment of a successor Relevant Trustee.
<PAGE>   49
                                                                              42



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

         Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative 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 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
<PAGE>   50
                                                                              43



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 written request of the Trust or any successor Relevant
Trustee such retiring Relevant Trustee shall, upon payment of its charges, duly
assign, transfer and deliver to such successor Relevant Trustee all Trust
Property, all proceeds thereof and money held by such retiring Relevant Trustee
hereunder with respect to the Trust Securities and the Trust.

         Upon written 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 preceding paragraph.

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

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

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

         SECTION 8.13  Preferential Collection of Claims Against Depositor or
Trust.

         In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
similar judicial proceeding relative to the Trust or any other obligor upon the
Trust Securities or the property of the Trust or of such other obligor or their
creditors, the Property Trustee (irrespective of whether any Distributions on
the Trust Securities shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Property Trustee shall
have made any demand on the Trust for the payment of any past due
Distributions) shall be entitled and empowered, to the fullest extent permitted
by law, by intervention in such proceeding or otherwise:
<PAGE>   51
                                                                              44



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

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Property Trustee and, in the event the
Property Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Property Trustee any amount due it for the reasonable
compensation, expenses, disbursements and advances of the Property Trustee, its
agents and counsel, and any other amounts due the Property Trustee.

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

         SECTION 8.14  Reports by Property Trustee.

         (a)  The Property Trustee shall transmit to Securityholders such
reports concerning the Property Trustee and its actions under this Trust
Agreement as may be required pursuant to the Trust Indenture Act at the times
and in the manner provided pursuant thereto.  If required by Section 313(a) of
the Trust Indenture Act, the Property Trustee shall, within sixty days after
each May 15 following the date of this Trust Agreement deliver to
Securityholders a brief report, dated as of such May 15, which complies with
the provisions of such Section 313(a).

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

         SECTION 8.15  Reports to the Property Trustee.

         The Depositor and the Administrative Trustees on behalf of the Trust
shall provide to the Property Trustee such documents, reports and information
as required by Section 314 of the Trust Indenture Act (if any) and the
compliance certificate required by Section 314(a) of the Trust Indenture Act in
the form, in the manner and at the times required by Section 314 of the Trust
Indenture Act.  Delivery of such reports, information and documents to the
Property Trustee is for informational purposes only and the Property Trustee's
receipt of
<PAGE>   52
                                                                              45



such shall not constitute constructive notice of any information contained
therein or determinable from information contained therein, including the
Trust's compliance with any of its covenants hereunder (as to which the
Property Trustee is entitled to rely exclusively on Officers' Certificates).

         SECTION 8.16  Evidence of Compliance with Conditions Precedent.

         Each of the Depositor and the Administrative Trustees on behalf of the
Trust shall provide to the Property Trustee such evidence of compliance with
any conditions precedent, if any, provided for in this Trust Agreement that
relate to any of the matters set forth in Section 314 (c) of the Trust
Indenture Act. Any certificate or opinion required to be given by an officer
pursuant to Section 314(c)(1) of the Trust Indenture Act shall be given in the
form of an Officers' Certificate.

         SECTION 8.17  Number of Trustees.

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

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

         (c) The death, resignation, retirement, removal, bankruptcy,
incompetence or incapacity to perform the duties of a Trustee shall not operate
to dissolve, terminate or 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
with applicable law, delegate to any other natural person over the age of 21
his or her power for the purpose of executing any documents contemplated in
Section 2.7(a), including any registration statement or amendment thereto filed
with the Commission, or making any other governmental filing; and

         (b) The Administrative Trustees shall have power to delegate from time
to time to such of their number or to the Depositor the doing of such things
and the execution of such instruments either in the name of the Trust or the
names of the Administrative Trustees or
<PAGE>   53
                                                                              46



otherwise as the Administrative Trustees may deem expedient, to the extent such
delegation is not prohibited by applicable law or contrary to the provisions of
this Trust Agreement, as set forth herein.


                                   ARTICLE IX

                      TERMINATION, LIQUIDATION AND MERGER

         SECTION 9.1  Termination Upon Expiration Date.

         Unless earlier terminated, the Trust shall automatically terminate on
____________, 20__ (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 Holder of the Common Securities;

         (b) the written direction to the Property Trustee from the Depositor
at any time to terminate the Trust and, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, distribute Debentures to
Securityholders in exchange for 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 of the Debentures; and

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

         SECTION 9.3  Termination.

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

         SECTION 9.4  Liquidation.
<PAGE>   54
                                                                              47




         (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 or the making of reasonable
provisions for the payment 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 CUSIP Number of the Trust 
         Securities;

                           (ii)    state the Liquidation Date;

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

                           (iv)    provide such information with respect to the
         mechanics by which Holders may exchange Trust Securities Certificates
         for Debentures, or if Section 9.4(d) applies 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 Property Trustee shall establish a record date for such
distribution (which shall be not more than 45 days prior to the Liquidation
Date) and, either itself acting as exchange agent or through the appointment of
a separate exchange agent, shall establish such procedures as it shall deem
appropriate to effect the distribution of Debentures in exchange for the
Outstanding Trust Securities Certificates.

         (c) Except where Section 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 or
traded, (iv) any Trust Securities Certificates not so surrendered for exchange
will be deemed to represent a Like Amount of Debentures, accruing interest at
the rate provided for in the Debentures from the last Distribution Date on
which a Distribution was made on such Trust Securities Certificates until such
certificates are so surrendered (and until such certificates are so
surrendered, no payments of interest or principal will be made to Holders of
Trust Securities Certificates with respect to such Debentures) and (v) all
rights of Securityholders holding Trust Securities will

                                                                              48



cease, except the right of such Securityholders to receive 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 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, the Preferred Securities shall have a priority
over the 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 Person, except
pursuant to this Article IX. 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 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

                                                                              49



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 Person or
permit any other Person 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 to be classified the successor entity
to be taxable as a corporation or as other than a grantor trust for United
States federal income tax purposes.

                            MISCELLANEOUS PROVISIONS

         SECTION 10.1  Limitation of Rights of Securityholders.

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

         SECTION 10.2  Liability of the Common Securityholder.

         The Holder of the Common Securities shall be liable for all of the
debts and obligations of the Trust (other than with respect to the Securities)
to the extent not satisfied out of the Trust's assets.

         SECTION 10.3   Amendment.

         (a) This Trust Agreement may be amended from time to time by the
Property Trustee, the Administrative Trustees and the Depositor, without the
consent of any
<PAGE>   57
                                                                              50



Securityholders, (i) to cure any ambiguity, correct or supplement any provision
herein which may be inconsistent with any other provision herein, or to make any
other provisions with respect to matters or questions arising under this Trust
Agreement, which shall not be inconsistent with the other provisions of this
Trust Agreement, or (ii) to modify, eliminate or add to any provisions of this
Trust Agreement to such extent as shall be necessary to ensure that the Trust
will be classified for United States federal income tax purposes as a grantor
trust and not be taxable as a corporation at all times that any Trust Securities
are outstanding or to ensure that the Trust will not be required to register as
an investment company under the 1940 Act; provided, however, that in the case of
clause (i) or clause (ii), such action shall not adversely affect in any
material respect the interests of any Securityholder, and any amendments of this
Trust Agreement shall become effective when notice thereof is given to the
Securityholders.

         (b) Except as provided in Section 10.3(c) hereof, any provision of this
Trust Agreement may be amended by the Trustees and the Depositor with (i) the
consent of Trust Securityholders representing not less than a majority (based
upon Liquidation Amounts) of the Trust Securities then Outstanding and (ii)
receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's exemption from status of an
investment company under the 1940 Act or the Trust's status as a grantor trust
for United States federal income tax purposes and will not result in the Trust
being taxable as a Corporation for United States federal income tax purposes.

         (c) In addition to and notwithstanding any other provision in this
Trust Agreement, without the consent of each affected Securityholder (such
consent being obtained in accordance with Section 6.3 or 6.6 hereof), this
Trust Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount
of any Distribution required to be made in respect of the Trust Securities as
of a specified date or (ii) restrict the right of a Securityholder to institute
suit for the enforcement of any such payment on or after such date;
notwithstanding any other provision herein, without the unanimous consent of
the Securityholders (such consent being obtained in accordance with Section 6.3
or 6.6 hereof), this paragraph (c) of this Section 10.3 may not be amended.

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

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

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

                                                                              51



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

         SECTION 10.4  Separability.

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

         SECTION 10.5  Governing Law.

         THIS TRUST AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF EACH OF THE
SECURITYHOLDERS, THE TRUST AND THE TRUSTEES WITH RESPECT TO THIS TRUST
AGREEMENT AND THE TRUST SECURITIES SHALL BE CONSTRUED IN ACCORDANCE WITH AND
GOVERNED BY THE LAWS OF THE STATE OF DELAWARE (WITHOUT REGARD TO CONFLICT OF
LAWS PRINCIPLES).

         SECTION 10.6  Payments Due on Non-Business Day.

         If the date fixed for any payment on any Trust Security shall be a day
that is not a Business Day, then such payment need not be made on such date but
may be made on the next succeeding day that is a Business Day (except as
otherwise provided in Sections 4.1(a) and 4.2(d)), with the same force and
effect as though made on the date fixed for such payment, and no interest shall
accrue thereon for the period after such date.

         SECTION 10.7  Successors.

         This Trust Agreement shall be binding upon and shall inure to the
benefit of any successor to the Depositor, the Trust or the Relevant Trustee,
including any successor by operation of law. Except in connection with a
consolidation, merger or sale involving the Depositor that is permitted under
Article Eight of the Indenture and pursuant to which the assignee agrees in
writing to perform the Depositor's obligations hereunder, the Depositor shall
not assign its obligations hereunder.

         SECTION 10.8  Headings.

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

         SECTION 10.9  Reports, Notices and Demands.

         Any report, notice, demand or other communication which by any
provision of this Trust Agreement is required or permitted to be given or
served to or upon any Securityholder or the Depositor may be given or served in
writing by deposit thereof, first-class postage prepaid, in the United States
mail, hand delivery or facsimile transmission, in each case, addressed, (a) in
the case of a Preferred Securityholder, to such Preferred Securityholder as
such Securityholder's name and address may appear on the Securities Register;

Tennessee National Corporation, 165 Madison Avenue, Memphis, Tennessee 38103,
Attention: Treasurer, facsimile no.: (901) 523-4336. Such notice, demand or
other communication to or upon a Securityholder shall be deemed to have been
sufficiently given or made, for all purposes, upon hand delivery, mailing or
transmission.

         Any notice, demand or other communication which by any provision of
this Trust Agreement is required or permitted to be given or served to or upon
the Trust, the Property Trustee, the Delaware Trustee or the Administrative
Trustees shall be given in writing addressed (until another address is published

deemed to have been sufficiently given or made only upon actual receipt of the
writing by the Trust, the Administrative Trustees or the Property Trustee.

         SECTION 10.10  Agreement Not to Petition.

         Each of the Trustees and the Depositor agree for the benefit of the
Securityholders that, until at least one year and one day after the Trust has
been terminated in accordance with Article IX, they shall not file, or join in
the filing of, a petition against the Trust under any bankruptcy, insolvency,
reorganization or other similar law (including, without limitation, the United
States Bankruptcy Code) (collectively, "Bankruptcy Laws") or otherwise join in
the commencement of any proceeding against the Trust under any Bankruptcy Law.
In the event the Depositor takes action in violation of this Section 10.10, the
Property Trustee agrees, for the benefit of Securityholders, that at the
expense of the Depositor, it shall file an answer with the bankruptcy court or
otherwise properly contest the filing of such petition by the Depositor against
the Trust or the commencement of such action and raise the defense that the
Depositor has agreed in writing not to take such action and should be stopped
and precluded therefrom and such other defenses, if any, as counsel for the
Trustee or the Trust may assert. The provisions of this Section 10.10 shall
survive the termination of this Trust Agreement.

         SECTION 10.11  Trust Indenture Act; Conflict with Trust Indenture Act.
<PAGE>   60
                                                                              53




         (a) This Trust Agreement is subject to the provisions of the Trust
Indenture Act that are required or deemed to be part of this Trust Agreement
and shall, to the extent applicable, be governed by such provisions.

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

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

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

         SECTION 10.12  Acceptance of Terms of Trust Agreement, Guarantee and
Indenture.

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

signature page and this Trust Agreement may be executed by the affixing of the

All of such counterpart signature pages shall be read as though one, and they
shall have the same force and effect as though all of the signers had signed a
single signature page.

                 Re:      First Tennessee Capital IV
                          ____% Preferred Securities, Series __
                          CUSIP                                     

Ladies and Gentlemen:

                 The purpose of this letter is to set forth certain matters
relating to the issuance and deposit with The Depository Trust Company ("DTC")
of the book-entry-only portion of the _____% Preferred Securities, Series _
(the "Preferred Securities"), of First Tennessee Capital IV, a statutory
business trust formed under the laws of the State of Delaware (the "Issuer"),
governed by the Amended and Restated Trust Agreement, dated as of _________ __,
199_, between First Tennessee National Corporation ("the Corporation"), as
Depositor, The Bank of New York, as Property Trustee, and The Bank of New York
(Delaware), as Delaware Trustee.  The payment of distributions on the Preferred
Securities and payments due upon liquidation of the Issuer or redemption of the
Preferred Securities, to the extent the Issuer has funds available for the
payment thereof, are guaranteed by the Corporation to the extent set forth in a
Guarantee Agreement, dated as of ________ __, 199_, between the Corporation and
The Bank of New York, as Guarantee Trustee with respect to the Preferred
Securities.  The Corporation and the Issuer propose to sell the Preferred
Securities to certain Underwriters (the "Underwriters") pursuant to an
Underwriting Agreement, dated as of _________ __, 199_, by and among the
Underwriters, the Issuer and the Corporation, and the Underwriters wish to take
delivery of the Preferred





                                      B-1

Securities through DTC.  The Bank of New York is acting as transfer agent and
registrar with respect to the Preferred Securities (the "Transfer Agent and
Registrar").

                 To induce DTC to accept the Preferred Securities as eligible
for deposit at DTC, and to act in accordance with DTC's rules with respect to
the Preferred Securities, the Issuer and the Transfer Agent and Registrar make
the following representations to DTC:

                 1.       Prior to the closing of the sale of the Preferred
Securities to the Underwriters on __________ __, 199_, there shall be deposited
with, or held by the Transfer Agent and Registrar as custodian for, DTC one or
more global certificates (individually and collectively, the "Global
Certificate") registered in the name of DTC's nominee, Cede & Co., representing
an aggregate of ________ 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
         Issuer or its agent for registration of transfer, exchange, or
         payment, and any certificate issued is registered in the name of Cede
         & Co. or in such other name as is requested by an authorized
         representative of DTC (and any payment is made to Cede & Co. or to
         such other entity as is requested by an authorized representative of
         DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE
         BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner
         hereof, Cede & Co., has an interest herein.

                 2.       The Amended and Restated Trust Agreement of the
Issuer provides for the voting by holders (with no provision for revocation of
consents or votes by subsequent holders) of the 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 Preferred Securities outstanding,
the Issuer or the Transfer Agent and Registrar shall send DTC a notice of such
event as soon as possible, but at least 5 business days prior to the effective
date of such event.

                 4.       In the event of any distribution on, or an offering
or issuance of rights with respect to, the 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 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
Preferred Securities or published by or on behalf of the Issuer (whether by
mail or publication, the "Publication Date").  Such notice





                                      B-2
<PAGE>   68
shall be sent to DTC by a secure means (e.g., legible telecopy, registered or
certified mail, overnight delivery) in a timely manner designed to assure that
such notice is in DTC's possession no later than the close of business on the
business day before the Publication Date.  The Issuer or the Transfer Agent and
Registrar will forward such notice either in a separate secure transmission for
each CUSIP number or in a secure transmission of multiple CUSIP numbers (if
applicable) that includes a manifest or list of each CUSIP number submitted in
that transmission.  (The party sending such notice shall have a method to
verify subsequently the use of such means and the timeliness of such notice.)
The Publication Date shall be not less than 30 calendar days nor more than 60
calendar days prior to the payment of any such distribution or any such
offering or issuance of rights with respect to the Preferred Securities.  After
establishing the amount of payment to be made on the Capital Securities, the
Issuer or the Transfer Agent and Registrar will notify DTC's Dividend
Department of such payment 5 business days prior to payment date.  Notices to
DTC's Dividend Department by telecopy shall be sent to (212) 709-1723.  Such

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

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

                                   Call Notification Department
                                   The Depository Trust Company

                                   Garden City, New York 11530-4719

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





                                      B-3
<PAGE>   69
receipt of such notice shall be confirmed by telephoning (212) 709-6884, or by
mail or any other means to:

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

                 7.       All notices and payment advices sent to DTC shall
contain the CUSIP number or numbers of the Preferred Securities and the
accompanying designation of the Preferred Securities, which, as of the date of
this letter, is "First Tennessee Capital IV, ____% Preferred Securities, Series
_".

                 8.       Distribution payments or other cash payments with
respect to the Preferred Securities shall be governed by DTC's current
Principal and Income Payments Rider, a copy of which is attached hereto as
Annex I.  For purposes of this letter, the term "Agent" used in Annex I shall
be deemed to refer to The Bank of New York or any successor Property Trustee
under the Amended and Restated Trust Agreement.

                 9.       DTC may 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 Preferred Securities outstanding evidenced
by the Global Certificate, DTC, in its discretion:  (a) may request the Issuer
or the Transfer Agent and Registrar to issue and countersign a new Global
Certificate; or (b) may make an appropriate notation on the Global Certificate
indicating the date and amount of such reduction.

                 11.  DTC may discontinue its services as a securities
depositary with respect to the Preferred Securities at any time by giving
reasonable 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 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 book-entry settlement for the Preferred Securities, make
available one or more separate global certificates evidencing Preferred
Securities to any Participant having Preferred Securities credited to its DTC
account, or issue definitive 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





                                      B-4
<PAGE>   70
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 Preferred Securities shall be able to obtain definitive
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

waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent therefrom.

         SECTION 2.7.   Event of Default; Notice.

         (a) The Guarantee Trustee shall, within 90 days after the occurrence

Payment, the Guarantee Trustee shall be protected in withholding such notice if

committee of the Board of Directors and/or Responsible Officers of the
Guarantee Trustee in good faith determines that the withholding of such notice
is in the interests of the Holders.

         (b) The Guarantee Trustee shall not be deemed to have knowledge of any

                                                                               6



         SECTION 2.8.   Conflicting Interests.

         The Trust Agreement shall be deemed to be specifically described in
this Guarantee Agreement for the purposes of clause (i) of the first proviso

       ARTICLE III.   POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

         SECTION 3.1.   Powers and Duties of the Guarantee Trustee.

         (a) This Guarantee Agreement shall be held by the Guarantee Trustee
for the benefit of the Holders, and the Guarantee Trustee shall not transfer
this Guarantee Agreement to any Person except a Holder exercising his or her
rights pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on
acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee
Trustee shall automatically vest in any Successor Guarantee Trustee, upon
acceptance by such Successor Guarantee Trustee of its appointment hereunder,
and such vesting and cessation of title shall be effective whether or not
conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Guarantee Trustee.

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

         (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

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

                 (A) the duties and obligations of the Guarantee Trustee shall
         be determined solely by the express provisions of this Guarantee
         Agreement, and the Guarantee Trustee shall not be liable for the
         performance of such duties and obligations as are specifically set
         forth in this Guarantee Agreement; and
<PAGE>   11
                                                                               7




                 (B) in the absence of bad faith on the part of the Guarantee
         Trustee, the Guarantee Trustee may conclusively rely, as to the truth
         of the statements and the correctness of the opinions expressed
         therein, upon any certificates or opinions furnished to the Guarantee
         Trustee and conforming to the requirements of this Guarantee
         Agreement; but in the case of any such certificates or opinions that
         by any provision hereof or of the Trust Indenture Act are specifically
         required to be furnished to the Guarantee Trustee, the Guarantee

         repayment of such funds or liability is not reasonably assured to it
         under the terms of this Guarantee Agreement or adequate indemnity
         against such risk or liability is not reasonably assured to it.

                 (iii) Whenever, in the administration of this Guarantee
         Agreement, the Guarantee Trustee shall deem it desirable that a matter
         be proved or established before taking, suffering or omitting to take
         any action hereunder, the Guarantee 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 from the Guarantee Trustee, shall be promptly
         delivered by the Guarantor.

                 (iv) The Guarantee Trustee may consult with legal counsel of

         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such
         Holder shall have provided to the Guarantee Trustee such adequate
         security and indemnity as would satisfy a reasonable person in the
         position of the Guarantee Trustee, against the costs, expenses
         (including attorneys' fees and expenses) and liabilities that might be
         incurred by it in complying with such request or direction, including
         such reasonable advances as may be requested by the Guarantee Trustee;
         provided that, nothing contained in this Section 3.2(a)(v) shall be
         taken to relieve the Guarantee Trustee, upon the occurrence of an
         Event of Default, of its obligation to exercise the rights and powers
         vested in it by this Guarantee Agreement.

                 (vi) The Guarantee Trustee shall not be bound to make any

         such facts or matters as it may see fit.

                 (vii) The Guarantee Trustee may execute any of the trusts or
         powers hereunder or perform any duties hereunder either directly or by

         Agreement the Guarantee Trustee shall deem it desirable to receive
         written instructions with respect to enforcing any remedy or right or
         taking any other action hereunder, the Guarantee Trustee (A) may
         request instructions from the Holders, (B) may refrain from enforcing
         such remedy or right or taking such other action until such written
         instructions are received, and (C) shall be protected in acting in

any duty or obligation on the Guarantee 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 Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

         SECTION 3.3.   Indemnity.

         The Guarantor agrees to indemnify the Guarantee Trustee for, and to
hold it harmless against, any loss, liability or expense incurred without

         SECTION 4.1.   Guarantee Trustee: Eligibility.

         (a) There shall at all times be a Guarantee Trustee which shall:

                 (i) not be an Affiliate of the Guarantor; and

                 (ii) be a Person that is eligible pursuant to the Trust

         at least $50,000,000, and shall be a corporation meeting the
         requirements of Section 310(a) of the Trust Indenture Act. If such
         corporation publishes reports of condition at least annually, pursuant
         to law or to the requirements of the supervising or examining
         authority, then, for the purposes of this Section and to the extent
         permitted by the Trust Indenture Act, the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

         (b) If at any time the Guarantee Trustee shall cease to be eligible to

         (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 310(b) of the Trust Indenture Act, the
Guarantee Trustee and Guarantor shall in all respects comply with the
provisions of Section 310(b) of the Trust Indenture Act.

         SECTION 4.2.   Appointment, Removal and Resignation of the Guarantee
Trustee.

         (a) Subject to Section 4.2(b), the Guarantee Trustee may be appointed
or removed without cause at any time by the Guarantor.

         (b) The Guarantee Trustee shall not be removed until a Successor
Guarantee Trustee has been appointed and has accepted such appointment by
written instrument executed by such Successor Guarantee Trustee and delivered
to the Guarantor.  If an instrument of acceptance by a Successor Guarantee
Trustee shall not have been delivered to the Guarantee Trustee within 30 days
after such removal, the Guarantee Trustee being removed may petition any court
of competent jurisdiction for the appointment of a Successor Guarantee Trustee.

         (c) The Guarantee Trustee appointed hereunder shall hold office until
a Successor Guarantee Trustee shall have been appointed or until its removal or
resignation. The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the
Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

         (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of resignation, the resigning
Guarantee Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for appointment of a Successor Guarantee Trustee. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Guarantee Trustee.

Holders against the Issuer in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement and shall have the right to waive
payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement, if, at the time of any
such payment, any amounts are due and unpaid under this Guarantee Agreement. If

sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

and effect upon (i) full payment of the Redemption Price of all Securities,
(ii) the distribution of Debentures to the Holders in exchange for all of the
Securities or (iii) full payment of the amounts payable in accordance with the
Trust Agreement upon liquidation of the Issuer. Notwithstanding the foregoing,
this Guarantee Agreement will continue to be effective or will be reinstated,

paid with respect to Securities or this Guarantee Agreement.

this Guarantee Agreement to any Person except a Holder exercising his or her
rights pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on
acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee
Trustee shall automatically vest in any Successor Guarantee Trustee, upon

shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

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

                 (A) the duties and obligations of the Guarantee Trustee shall
         be determined solely by the express provisions of this Guarantee
         Agreement, and the Guarantee Trustee shall not be liable for the
         performance of such duties and obligations as are specifically set
         forth in this Guarantee Agreement; and

                                                                               7




                 (B) in the absence of bad faith on the part of the Guarantee
         Trustee, the Guarantee Trustee may conclusively rely, as to the truth

         therein, upon any certificates or opinions furnished to the Guarantee
         Trustee and conforming to the requirements of this Guarantee
         Agreement; but in the case of any such certificates or opinions that
         by any provision hereof or of the Trust Indenture Act are specifically
         required to be furnished to the Guarantee Trustee, the Guarantee
         Trustee shall be under a duty to examine the same to determine whether
         or not they conform to the requirements of this Guarantee Agreement;

                 (ii) the Guarantee Trustee shall not be liable for any error
         of judgment made in good faith by a Responsible Officer of the
         Guarantee Trustee, unless it shall be proved that the Guarantee
         Trustee was negligent in ascertaining the pertinent facts upon which
         such judgment was made;

                 (iii) the Guarantee 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 aggregate Liquidation Amount of the Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Guarantee Trustee, or exercising any trust or power
         conferred upon the Guarantee Trustee under this Guarantee Agreement;
         and

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

         SECTION 3.2.   Certain Rights of Guarantee Trustee.

         (a) Subject to the provisions of Section 3.1:

                  (i) The Guarantee Trustee may rely and shall be fully

         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such
         Holder shall have provided to the Guarantee Trustee such adequate
         security and indemnity as would satisfy a reasonable person in the
         position of the Guarantee Trustee, against the costs, expenses
         (including attorneys' fees and expenses) and liabilities that might be
         incurred by it in complying with such request or direction, including
         such reasonable advances as may be requested by the Guarantee Trustee;
         provided that, nothing contained in this Section 3.2(a)(v) shall be
         taken to relieve the Guarantee Trustee, upon the occurrence of an

         vested in it by this Guarantee Agreement.

         such facts or matters as it may see fit.

                (vii) The Guarantee Trustee may execute any of the trusts or

         Agreement the Guarantee Trustee shall deem it desirable to receive

jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or

         (a) Subject to Section 4.2(b), the Guarantee Trustee may be appointed
or removed without cause at any time by the Guarantor.

         (b) The Guarantee Trustee shall not be removed until a Successor
Guarantee Trustee has been appointed and has accepted such appointment by
written instrument executed by such Successor Guarantee Trustee and delivered
to the Guarantor.  If an instrument of acceptance by a Successor Guarantee
Trustee shall not have been delivered to the Guarantee Trustee within 30 days
after such removal, the Guarantee Trustee being removed may petition any court
of competent jurisdiction for the appointment of a Successor Guarantee Trustee.

         (c) The Guarantee Trustee appointed hereunder shall hold office until
a Successor Guarantee Trustee shall have been appointed or until its removal or
resignation. The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the
Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

         (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of resignation, the resigning
Guarantee Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for appointment of a Successor Guarantee Trustee. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Guarantee Trustee.

                                                                              12

consent of, the Guarantor with respect to the happening of any of the
foregoing.

Agreement will be deposited with the Guarantee Trustee to be held for the
benefit of the Holders; (ii) the Guarantee Trustee has the right to enforce
this Guarantee Agreement on behalf of the Holders; (iii) the Holders of a
Majority in liquidation preference of the Securities have the right to direct
the time, method and place of conducting any proceeding for any remedy
available to the Guarantee Trustee in respect of this Guarantee Agreement or
exercising any trust or power conferred upon the Guarantee Trustee under this
Guarantee Agreement; and (iv) any Holder may institute a legal proceeding

Agreement, without first instituting a legal proceeding against the Guarantee
Trustee, the Issuer or any other Person.

         SECTION 5.5.   Guarantee of Payment.

         This Guarantee Agreement creates a guarantee of payment and not of

in the Trust Agreement.

         SECTION 5.6.   Subrogation.

         The Guarantor shall be subrogated to all (if any) rights of the
Holders against the Issuer in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement and shall have the right to waive
payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement, if, at the time of any
such payment, any amounts are due and unpaid under this Guarantee Agreement. If
any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 5.3 hereof.

         SECTION 6.1.   Subordination.

such obligations expressly by their terms, in the same manner as set forth in
Article XIII of the Indenture.

         SECTION 6.2.   Pari Passu Guarantees.

(ii) the distribution of Debentures to the Holders in exchange for all of the
Securities or (iii) full payment of the amounts payable in accordance with the
Trust Agreement upon liquidation of the Issuer. Notwithstanding the foregoing,
this Guarantee Agreement will continue to be effective or will be reinstated,
as the case may be, if at any time any Holder must restore payment of any sums
paid with respect to Securities or this Guarantee Agreement.


                         ARTICLE VIII.   MISCELLANEOUS

         SECTION 8.1.   Successors and Assigns.

         SECTION 2.6.   Events of Default; Waiver.

         The Holders of a Majority in aggregate Liquidation Amount of the
Securities may, by vote, on behalf of the Holders, waive any past Event of
Default and its consequences. Upon such waiver, any such Event of Default shall
cease to exist, and any Event of Default arising therefrom shall be deemed to
have been cured, for every purpose of this Guarantee Agreement, but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent therefrom.

         SECTION 2.7.   Event of Default; Notice.

         (a) The Guarantee Trustee shall, within 90 days after the occurrence
of an Event of Default, transmit by mail, first class postage prepaid, to the
Holders, notices of all Events of Default actually known to the Guarantee
Trustee, unless such defaults have been cured before the giving of such notice,
provided, that, except in the case of a default in the payment of a Guarantee
Payment, the Guarantee Trustee shall be protected in withholding such notice if
and so long as the Board of Directors, the executive committee or a trust
committee of the Board of Directors and/or Responsible Officers of the
Guarantee Trustee in good faith determines that the withholding of such notice
is in the interests of the Holders.

         (b) The Guarantee Trustee shall not be deemed to have knowledge of any
Event of Default unless the Guarantee Trustee shall have received written
notice, or a Responsible Officer charged with the administration of this
Guarantee Agreement shall have obtained written notice, of such Event of
Default.

       ARTICLE III.   POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

         SECTION 3.1.   Powers and Duties of the Guarantee Trustee.

         (a) This Guarantee Agreement shall be held by the Guarantee Trustee
for the benefit of the Holders, and the Guarantee Trustee shall not transfer
this Guarantee Agreement to any Person except a Holder exercising his or her
rights pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on
acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee
Trustee shall automatically vest in any Successor Guarantee Trustee, upon
acceptance by such Successor Guarantee Trustee of its appointment hereunder,
and such vesting and cessation of title shall be effective whether or not
conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Guarantee Trustee.

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

         (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

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

                 (A) the duties and obligations of the Guarantee Trustee shall
         be determined solely by the express provisions of this Guarantee
         Agreement, and the Guarantee Trustee shall not be liable for the
         performance of such duties and obligations as are specifically set
         forth in this Guarantee Agreement; and
<PAGE>   11
                                                                               7




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

                 (ii) the Guarantee Trustee shall not be liable for any error
         of judgment made in good faith by a Responsible Officer of the
         Guarantee Trustee, unless it shall be proved that the Guarantee
         Trustee was negligent in ascertaining the pertinent facts upon which
         such judgment was made;

                 (iii) the Guarantee 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 aggregate Liquidation Amount of the Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Guarantee Trustee, or exercising any trust or power
         conferred upon the Guarantee Trustee under this Guarantee Agreement;
         and

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

         SECTION 3.2.   Certain Rights of Guarantee Trustee.

         (a) Subject to the provisions of Section 3.1:

                 (i) The Guarantee Trustee may rely and shall be fully
         protected in acting or refraining from acting upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document reasonably believed by it to
         be genuine and to have been signed, sent or presented by the proper
         party or parties.

                 (ii) Any direction or act of the Guarantor contemplated by
         this Guarantee Agreement shall be sufficiently evidenced by an
         Officers' Certificate unless otherwise prescribed herein.

                                                                               8



                 (iii) Whenever, in the administration of this Guarantee
         Agreement, the Guarantee Trustee shall deem it desirable that a matter
         be proved or established before taking, suffering or omitting to take
         any action hereunder, the Guarantee 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 from the Guarantee Trustee, shall be promptly
         delivered by the Guarantor.

                 (iv) The Guarantee Trustee may consult with legal counsel of
         its selection, and the written advice or opinion of such legal counsel
         with respect to legal matters shall be full and complete authorization
         and protection in respect of any action taken, suffered or omitted to
         be taken by it hereunder in good faith and in accordance with such
         advice or opinion.  Such legal counsel may be legal counsel to the
         Guarantor or any of its Affiliates and may be one of its employees.
         The Guarantee Trustee shall have the right at any time to seek
         instructions concerning the administration of this Guarantee Agreement
         from any court of competent jurisdiction.

                 (v) The Guarantee Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such
         Holder shall have provided to the Guarantee Trustee such adequate
         security and indemnity as would satisfy a reasonable person in the
         position of the Guarantee Trustee, against the costs, expenses
         (including attorneys' fees and expenses) and liabilities that might be
         incurred by it in complying with such request or direction, including
         such reasonable advances as may be requested by the Guarantee Trustee;
         provided that, nothing contained in this Section 3.2(a)(v) shall be
         taken to relieve the Guarantee Trustee, upon the occurrence of an
         Event of Default, of its obligation to exercise the rights and powers
         vested in it by this Guarantee Agreement.

                 (vi) The Guarantee Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,

         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document, but the Guarantee Trustee, in
         its discretion, may make such further inquiry or investigation into
         such facts or matters as it may see fit.

                 (vii) The Guarantee Trustee may execute any of the trusts or
         powers hereunder or perform any duties hereunder either directly or by
         or through its agents or attorneys, and the Guarantee Trustee shall
         not be responsible for any misconduct or negligence on the part of any
         such agent or attorney appointed with due care by it hereunder.

                 (viii) Whenever in the administration of this Guarantee
         Agreement the Guarantee Trustee shall deem it desirable to receive
         written instructions with respect to enforcing any remedy or right or
         taking any other action hereunder, the Guarantee Trustee (A) may
         request instructions from the Holders, (B) may refrain from enforcing
         such remedy or right or taking such other action until such written
         instructions are received, and (C) shall be protected in acting in
         accordance with such written instructions.

         taken, suffered, or omitted to be taken by it in good faith and
         reasonably believed by it to be authorized or within the discretion or
         rights or powers conferred upon it by this Guarantee Agreement.

         (b) No provision of this Guarantee Agreement shall be deemed to impose
any duty or obligation on the Guarantee 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 Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

         SECTION 3.3.   Indemnity.

         The Guarantor agrees to indemnify the Guarantee Trustee for, and to
hold it harmless against, any loss, liability or expense incurred without
negligence or bad faith on the part of the Guarantee Trustee, arising out of or
in connection with the acceptance or administration of this Guarantee
Agreement, including the costs and expenses of defending itself against any

                 (i) not be an Affiliate of the Guarantor; and

         corporation publishes reports of condition at least annually, pursuant
         to law or to the requirements of the supervising or examining
         authority, then, for the purposes of this Section and to the extent
         permitted by the Trust Indenture Act, the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

         (b) If at any time the Guarantee Trustee shall cease to be eligible to

         (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 310(b) of the Trust Indenture Act, the
Guarantee Trustee and Guarantor shall in all respects comply with the
provisions of Section 310(b) of the Trust Indenture Act.

         SECTION 4.2.   Appointment, Removal and Resignation of the Guarantee
Trustee.

         (a) Subject to Section 4.2(b), the Guarantee Trustee may be appointed
or removed without cause at any time by the Guarantor.

         (b) The Guarantee Trustee shall not be removed until a Successor
Guarantee Trustee has been appointed and has accepted such appointment by
written instrument executed by such Successor Guarantee Trustee and delivered
to the Guarantor.  If an instrument of acceptance by a Successor Guarantee
Trustee shall not have been delivered to the Guarantee Trustee within 30 days
after such removal, the Guarantee Trustee being removed may petition any court
of competent jurisdiction for the appointment of a Successor Guarantee Trustee.

         (c) The Guarantee Trustee appointed hereunder shall hold office until
a Successor Guarantee Trustee shall have been appointed or until its removal or
resignation. The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the
Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

         (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of resignation, the resigning
Guarantee Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for appointment of a Successor Guarantee Trustee. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Guarantee Trustee.

defense, right of set-off or counterclaim which the Issuer may have or assert.
The Guarantor's obligation to make a Guarantee Payment may be satisfied by
direct payment of the required amounts by the Guarantor to the Holders or by
causing the Issuer to pay such amounts to the Holders.

Distribution or any other sums payable under the terms of the Securities or the
extension of time for the performance of any other obligation under, arising

payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement, if, at the time of any

and effect upon (i) full payment of the Redemption Price of all Securities,
(ii) the distribution of Debentures to the Holders in exchange for all of the
Securities or (iii) full payment of the amounts payable in accordance with the
Trust Agreement upon liquidation of the Issuer. Notwithstanding the foregoing,
this Guarantee Agreement will continue to be effective or will be reinstated,

paid with respect to Securities or this Guarantee Agreement.

       ARTICLE III.   POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE

         SECTION 3.1.   Powers and Duties of the Guarantee Trustee.

         (a) This Guarantee Agreement shall be held by the Guarantee Trustee
for the benefit of the Holders, and the Guarantee Trustee shall not transfer
this Guarantee Agreement to any Person except a Holder exercising his or her
rights pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on
acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee
Trustee shall automatically vest in any Successor Guarantee Trustee, upon
acceptance by such Successor Guarantee Trustee of its appointment hereunder,
and such vesting and cessation of title shall be effective whether or not
conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Guarantee Trustee.

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

         (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing of all Events of Default that may have occurred,
shall undertake to perform only such duties as are specifically set forth in
this Guarantee Agreement, and no implied covenants shall be read into this
Guarantee Agreement against the Guarantee Trustee. In case an Event of Default
has occurred (that has not been cured or waived pursuant to Section 2.6), the
Guarantee Trustee shall exercise such of the rights and powers vested in it by
this Guarantee Agreement, and use the same degree of care and skill in its
exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

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

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

                 (A) the duties and obligations of the Guarantee Trustee shall
         be determined solely by the express provisions of this Guarantee
         Agreement, and the Guarantee Trustee shall not be liable for the
         performance of such duties and obligations as are specifically set
         forth in this Guarantee Agreement; and
<PAGE>   11
                                                                               7




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

                 (ii) the Guarantee Trustee shall not be liable for any error
         of judgment made in good faith by a Responsible Officer of the
         Guarantee Trustee, unless it shall be proved that the Guarantee
         Trustee was negligent in ascertaining the pertinent facts upon which
         such judgment was made;

                 (iii) the Guarantee 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 aggregate Liquidation Amount of the Securities relating to
         the time, method and place of conducting any proceeding for any remedy
         available to the Guarantee Trustee, or exercising any trust or power
         conferred upon the Guarantee Trustee under this Guarantee Agreement;
         and

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

         SECTION 3.2.   Certain Rights of Guarantee Trustee.

         (a) Subject to the provisions of Section 3.1:

                 (i) The Guarantee Trustee may rely and shall be fully

         indebtedness or other paper or document reasonably believed by it to

         party or parties.

                 (ii) Any direction or act of the Guarantor contemplated by

                 (iii) Whenever, in the administration of this Guarantee
         Agreement, the Guarantee Trustee shall deem it desirable that a matter
         be proved or established before taking, suffering or omitting to take
         any action hereunder, the Guarantee 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 from the Guarantee Trustee, shall be promptly
         delivered by the Guarantor.

                 (iv) The Guarantee Trustee may consult with legal counsel of
         its selection, and the written advice or opinion of such legal counsel
         with respect to legal matters shall be full and complete authorization
         and protection in respect of any action taken, suffered or omitted to
         be taken by it hereunder in good faith and in accordance with such
         advice or opinion.  Such legal counsel may be legal counsel to the
         Guarantor or any of its Affiliates and may be one of its employees.
         The Guarantee Trustee shall have the right at any time to seek
         instructions concerning the administration of this Guarantee Agreement
         from any court of competent jurisdiction.

                 (v) The Guarantee Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such
         Holder shall have provided to the Guarantee Trustee such adequate
         security and indemnity as would satisfy a reasonable person in the
         position of the Guarantee Trustee, against the costs, expenses
         (including attorneys' fees and expenses) and liabilities that might be
         incurred by it in complying with such request or direction, including
         such reasonable advances as may be requested by the Guarantee Trustee;
         provided that, nothing contained in this Section 3.2(a)(v) shall be
         taken to relieve the Guarantee Trustee, upon the occurrence of an
         Event of Default, of its obligation to exercise the rights and powers
         vested in it by this Guarantee Agreement.

                 (vi) The Guarantee 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,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document, but the Guarantee Trustee, in
         its discretion, may make such further inquiry or investigation into
         such facts or matters as it may see fit.

                 (vii) The Guarantee Trustee may execute any of the trusts or
         powers hereunder or perform any duties hereunder either directly or by
         or through its agents or attorneys, and the Guarantee Trustee shall
         not be responsible for any misconduct or negligence on the part of any
         such agent or attorney appointed with due care by it hereunder.

                 (viii) Whenever in the administration of this Guarantee
         Agreement the Guarantee Trustee shall deem it desirable to receive
         written instructions with respect to enforcing any remedy or right or
         taking any other action hereunder, the Guarantee Trustee (A) may
         request instructions from the Holders, (B) may refrain from enforcing
         such remedy or right or taking such other action until such written
         instructions are received, and (C) shall be protected in acting in
         accordance with such written instructions.

                 (ix)  The Guarantee Trustee shall not be liable for any action
         taken, suffered, or omitted to be taken by it in good faith and
         reasonably believed by it to be authorized or within the discretion or
         rights or powers conferred upon it by this Guarantee Agreement.

         (b) No provision of this Guarantee Agreement shall be deemed to impose
any duty or obligation on the Guarantee 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 Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

         SECTION 3.3.   Indemnity.

         The Guarantor agrees to indemnify the Guarantee Trustee for, and to
hold it harmless against, any loss, liability or expense incurred without
negligence or bad faith on the part of the Guarantee Trustee, arising out of or
in connection with the acceptance or administration of this Guarantee
Agreement, including the costs and expenses of defending itself against any
claim or liability in connection with the exercise or performance of any of its
powers or duties hereunder.

                        ARTICLE IV.   GUARANTEE TRUSTEE

         SECTION 4.1.   Guarantee Trustee: Eligibility.

         (a) There shall at all times be a Guarantee Trustee which shall:

                 (i) not be an Affiliate of the Guarantor; and

                 (ii) 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, and shall be a corporation meeting the
         requirements of Section 310(a) of the Trust Indenture Act. If such
         corporation publishes reports of condition at least annually, pursuant
         to law or to the requirements of the supervising or examining
         authority, then, for the purposes of this Section and to the extent
         permitted by the Trust Indenture Act, the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

         (b) If at any time the Guarantee Trustee shall cease to be eligible to
so act under Section 4.1(a), the Guarantee Trustee shall immediately resign in
the manner and with the effect set out in Section 4.2(c).

                                                                              10



         (c) If the Guarantee Trustee has or shall acquire any "conflicting
interest" within the meaning of Section 310(b) of the Trust Indenture Act, the
Guarantee Trustee and Guarantor shall in all respects comply with the
provisions of Section 310(b) of the Trust Indenture Act.

         SECTION 4.2.   Appointment, Removal and Resignation of the Guarantee
Trustee.

         (a) Subject to Section 4.2(b), the Guarantee Trustee may be appointed
or removed without cause at any time by the Guarantor.

         (b) The Guarantee Trustee shall not be removed until a Successor
Guarantee Trustee has been appointed and has accepted such appointment by
written instrument executed by such Successor Guarantee Trustee and delivered
to the Guarantor.  If an instrument of acceptance by a Successor Guarantee
Trustee shall not have been delivered to the Guarantee Trustee within 30 days
after such removal, the Guarantee Trustee being removed may petition any court
of competent jurisdiction for the appointment of a Successor Guarantee Trustee.

         (c) The Guarantee Trustee appointed hereunder shall hold office until
a Successor Guarantee Trustee shall have been appointed or until its removal or
resignation. The Guarantee Trustee may resign from office (without need for
prior or subsequent accounting) by an instrument in writing executed by the
Guarantee Trustee and delivered to the Guarantor, which resignation shall not
take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

         (d) If no Successor Guarantee Trustee shall have been appointed and
accepted appointment as provided in this Section 4.2 within 60 days after
delivery to the Guarantor of an instrument of resignation, the resigning
Guarantee Trustee may petition, at the expense of the Guarantor, any court of
competent jurisdiction for appointment of a Successor Guarantee Trustee. Such
court may thereupon, after prescribing such notice, if any, as it may deem
proper, appoint a Successor Guarantee Trustee.

         SECTION 5.1.   Guarantee.

         The Guarantor irrevocably and unconditionally agrees to pay in full to

paid by or on behalf of the Issuer), as and when due, regardless of any
defense, right of set-off or counterclaim which the Issuer may have or assert.
The Guarantor's obligation to make a Guarantee Payment may be satisfied by
direct payment of the required amounts by the Guarantor to the Holders or by
causing the Issuer to pay such amounts to the Holders.

                                                                              11

         SECTION 5.3.   Obligations Not Affected.

performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Securities to be performed or
observed by the Issuer;

         (b) the extension of time for the payment by the Issuer of all or any
portion of the Distributions (other than an extension of time for payment of
Distributions that results from the extension of any interest payment period on
the Debentures as provided in the Indenture), Redemption Price, Liquidation
Distribution or any other sums payable under the terms of the Securities or the
extension of time for the performance of any other obligation under, arising
out of, or in connection with, the Securities;

         (c) any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or
remedy conferred on the Holders pursuant to the terms of the Securities, or any
action on the part of the Issuer granting indulgence or extension of any kind;

         (d) the voluntary or involuntary liquidation, dissolution, sale of any
collateral, receivership, insolvency, bankruptcy, assignment for the benefit of
creditors, reorganization, arrangement, composition or readjustment of debt of,

Issuer;

         (e) any invalidity of, or defect or deficiency in, the Securities;

         (f) the settlement or compromise of any obligation guaranteed hereby
or hereby incurred; or

         (g) any other circumstance whatsoever that might otherwise constitute
a legal or equitable discharge or defense of a guarantor, it being the intent
of this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances.
<PAGE>   16
                                                                              12

consent of, the Guarantor with respect to the happening of any of the
foregoing.

         The Guarantor expressly acknowledges that: (i) this Guarantee
Agreement will be deposited with the Guarantee Trustee to be held for the
benefit of the Holders; (ii) the Guarantee Trustee has the right to enforce
this Guarantee Agreement on behalf of the Holders; (iii) the Holders of a
Majority in liquidation preference of the Securities have the right to direct
the time, method and place of conducting any proceeding for any remedy
available to the Guarantee Trustee in respect of this Guarantee Agreement or
exercising any trust or power conferred upon the Guarantee Trustee under this
Guarantee Agreement; and (iv) any Holder may institute a legal proceeding
directly against the Guarantor to enforce its rights under this Guarantee
Agreement, without first instituting a legal proceeding against the Guarantee
Trustee, the Issuer or any other Person.

         SECTION 5.5.   Guarantee of Payment.

         This Guarantee Agreement creates a guarantee of payment and not of

paid by the Issuer) or upon distribution of Debentures to Holders as provided
in the Trust Agreement.

         SECTION 5.6.   Subrogation.

         The Guarantor shall be subrogated to all (if any) rights of the
Holders against the Issuer in respect of any amounts paid to the Holders by the
Guarantor under this Guarantee Agreement and shall have the right to waive
payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement, if, at the time of any
such payment, any amounts are due and unpaid under this Guarantee Agreement. If
any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

         SECTION 5.7.   Independent Obligations.

         The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Securities and

Guarantee Payments pursuant to the terms of this Guarantee Agreement
notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 5.3 hereof.

         SECTION 6.1.   Subordination.

         The obligations of the Guarantor under this Guarantee Agreement will

such obligations expressly by their terms, in the same manner as set forth in
Article XIII of the Indenture.

         SECTION 6.2.   Pari Passu Guarantees.

         The obligations of the Guarantor under this Guarantee Agreement shall
rank pari passu with the obligations of the Guarantor under any similar

preferred securities issued by any Trust (as defined in the Indenture).

and effect upon (i) full payment of the Redemption Price of all Securities,
(ii) the distribution of Debentures to the Holders in exchange for all of the
Securities or (iii) full payment of the amounts payable in accordance with the
Trust Agreement upon liquidation of the Issuer. Notwithstanding the foregoing,
this Guarantee Agreement will continue to be effective or will be reinstated,
as the case may be, if at any time any Holder must restore payment of any sums
paid with respect to Securities or this Guarantee Agreement.


                         ARTICLE VIII.   MISCELLANEOUS

         SECTION 8.1.   Successors and Assigns.
