the Series A Issuer. The Series A Issuer exists for the sole purpose of issuing
the Series A Capital Securities and the Series A Common Securities and investing
the proceeds thereof in $103,093,000 aggregate principal amount of 8.07% 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 January 6, 2027 (which date may be
shortened to a date not earlier than January 6, 2017 in certain circumstances as
described under "Certain Terms of Series A Subordinated
Debentures -- Conditional Right to Shorten Maturity or Redeem upon a Tax Event
or Capital Treatment Event" upon the occurrence of a Tax Event or a Capital
Treatment Event (each as defined herein) 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
Capital Securities 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.
 
     The Series A Capital Securities will constitute "Preferred Securities" as
described in the accompanying Prospectus. Holders of the Series A Capital
Securities will be entitled to receive preferential cumulative cash
distributions accruing from the date of original issuance and payable
semi-annually in arrears on January 6 and July 6 of each year, commencing July
6, 1997, at the annual rate of 8.07% of the Liquidation Amount (as defined in
the accompanying Prospectus) of $1,000 per Series A Capital Security
("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 10 consecutive semi-annual periods 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 8.07%,
compounded semi-annually, 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 Capital Securities
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
Capital Securities are entitled will accumulate) at the rate of 8.07% per annum,
compounded semi-annually from the relevant payment date for such interest, and
holders of Series A Capital Securities will be required to recognize income (in
the form of original issue discount) 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
 
                                       S-2

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 Capital Securities) 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 Capital Securities. 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 Capital Securities, 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 Capital Securities. 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 Capital Securities 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 Capital Securities 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 January 6,
2007, in whole at any time or in part from time to time, or (ii) at any time in
certain circumstances as described under "Certain Terms of Series A Subordinated
Debentures -- Conditional Right to Shorten Maturity or Redeem upon a Tax Event
or Capital Treatment Event", in whole (but not in part), upon the occurrence of
a Tax Event or a 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. For a description of
the redemption prices for the Series A Capital Securities pursuant to clause (i)
or (ii) above, see "Certain Terms of Series A Capital Securities -- 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. The Corporation has committed to the Reserve Bank that it will not cause
any such termination of 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. See "Certain Terms of Series A
Capital Securities -- 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 Capital
Securities will be entitled to receive a Liquidation Amount of $1,000 per Series
A Capital Security 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.
 
     The Series A Capital Securities 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 Capital Securities 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 Capital Securities in certificated form will not be issued in exchange for the
global certificates. See "Certain Terms of Series A Capital
Securities -- Registration of Series A Capital Securities".

     The information in this Prospectus Supplement supplements, and should be
read in conjunction with, the information contained in the accompanying
Prospectus. As used herein, (i) the "Indenture" means the Junior Subordinated
Indenture, as amended and supplemented from time to time, between the
Corporation and The Bank of New York, as trustee (the "Debenture Trustee"), and
(ii) the "Trust Agreement" means the Amended and Restated Trust Agreement
relating to the Series A Issuer among the Corporation, as Depositor, The Bank of
New York, as Property Trustee (the "Property Trustee"), The Bank of New York
(Delaware), as Delaware Trustee (the "Delaware Trustee"), and the Administrative
Trustees named therein (collectively, with the Property Trustee and Delaware
Trustee, the "Issuer Trustees"). Each of the other capitalized terms used in
this Prospectus Supplement and not otherwise defined in this Prospectus
Supplement has the meaning set forth in the accompanying Prospectus.

                                  RISK FACTORS
 
     Prospective purchasers of the Series A Capital Securities 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 Capital Securities may receive
Series A Subordinated Debentures in exchange therefor upon liquidation of the
Series A Issuer, prospective purchasers of Series A Capital Securities 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
Capital Securities 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 10 consecutive semi-annual periods 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, semi-annual Distributions on the Series A Capital Securities
by the Series A Issuer will also be deferred (and the amount of Distributions to
which holders of the Series A Capital Securities are entitled will accumulate
additional Distributions thereon at the rate of 8.07% per annum, compounded
semi-annually 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
 
                                       S-6
<PAGE>   7
 
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, 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 10 consecutive semi-annual periods 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 8.07%, compounded semi-annually 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 Capital Securities -- Distributions" and "Certain Terms of Series A
Subordinated Debentures -- Option to Defer Interest Payments".
 
     Should an Extension Period occur, a holder of Series A Capital Securities
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 Capital Securities 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 Capital Securities 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 Capital
Securities".
 
     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 Capital Securities is likely to be affected. A holder that disposes
of its Series A Capital Securities during an Extension Period, therefore, might
not receive the same return on its investment as a holder that continues to hold
its Series A Capital Securities.
 
TAX EVENT OR CAPITAL TREATMENT EVENT -- EXCHANGE OF SERIES A CAPITAL SECURITIES
FOR SERIES A SUBORDINATED DEBENTURES, SHORTENING OF MATURITY OF SERIES A
SUBORDINATED DEBENTURES OR REDEMPTION
 
     Upon the occurrence of a Tax Event or a Capital Treatment Event (whether
occurring before or after January 6, 2007), the Corporation has the right, if
certain conditions are met, (i) to terminate the Series A Issuer and cause the
Series A Subordinated Debentures to be distributed to the holders of the Series
A Capital Securities in exchange therefor upon liquidation of the Series A
Issuer, (ii) to shorten the maturity of the Series A Subordinated Debentures to
a date not earlier than January 6, 2017, or (iii) 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 Capital Securities. The Corporation has
committed to the Reserve Bank that it will not cause any such distribution,
shortening of the maturity or 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
Subordinated Debentures -- Conditional Right to Shorten Maturity or Redeem upon
a Tax Event or Capital Treatment Event".
 
                                       S-7
<PAGE>   8
 
     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 Capital Securities 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 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 (each of the circumstances referred to in
clauses (i), (ii) and (iii) of the preceding sentence and the circumstances
referred to in this sentence being referred to herein as an "Adverse Tax
Consequence").
 
     See " -- Possible Tax Law Changes Affecting the Series A Capital
Securities" for a discussion of certain legislative proposals that, if adopted,
could give rise to a Tax Event, which may permit the Corporation to shorten the
maturity of the Series A Subordinated Debentures or cause a redemption of the
Series A Capital Securities prior to January 6, 2007.
 
     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 Capital Securities
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 Capital Securities 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 CAPITAL SECURITIES 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 Securities in exchange therefor
upon liquidation of the Series A Issuer. The Corporation has committed to the
Reserve Bank that it will not terminate the Series A Issuer and cause such
distribution of the Series A Subordinated Debentures without having received the
prior approval of the Federal
 
                                       S-8
<PAGE>   9
 
Reserve to do so, if then required under applicable Federal Reserve capital
guidelines or policies. See "Certain Terms of Series A Capital Securities --
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 will not be a taxable event to holders of the Series A Capital
Securities. 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 Capital Securities.
See "Certain Federal Income Tax Consequences -- Distribution of Series A
Subordinated Debentures to Holders of Series A Capital Securities".
 
SHORTENING OF STATED MATURITY OF SERIES A SUBORDINATED DEBENTURES
 
     Upon the occurrence of a Tax Event or a Capital Treatment Event, the
Corporation in certain circumstances will have the right to shorten the maturity
of the Series A Subordinated Debentures to a date not earlier than January 6,
2017 and thereby cause the Series A Capital Securities to be redeemed on such
earlier date. See "Certain Terms of Series A Subordinated Debentures --
Conditional Right to Shorten Maturity or Redeem upon a Tax Event or Capital
Treatment Event".
 
MARKET PRICES
 
     There can be no assurance as to the market prices for Series A Capital
Securities or Series A Subordinated Debentures that may be distributed in
exchange for Series A Capital Securities upon liquidation of the Series A
Issuer. Accordingly, the Series A Capital Securities 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 Capital
Securities 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 Capital
Securities offered hereby. As a result of the existence of the Corporation's
right to defer interest payments, the market price of the Series A Capital
Securities (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. 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 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
 
                                       S-9
<PAGE>   10
 
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 Capital Securities generally will have limited voting
rights relating only to the modification of the Series A Capital Securities 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 Capital Securities
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,
the Administrative Trustees and the Corporation may amend the Trust Agreement
without the consent of holders of Series A Capital Securities to ensure that the
Series A Issuer will not be taxable as a corporation and will be 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 CAPITAL SECURITIES
 
     The Corporation does not intend to have the Series A Capital Securities
listed or approved for quotation on any securities exchange or automated
quotation system. The Series A Capital Securities may trade at prices that do
not fully reflect the value of accrued and unpaid interest with
 
                                      S-10
<PAGE>   11
 
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 Capital Securities" for a discussion of the
United States federal income tax consequences that may result from a taxable
disposition of the Series A Capital Securities.
 
POSSIBLE TAX LAW CHANGES AFFECTING THE SERIES A CAPITAL SECURITIES
 
     On March 19, 1996, the Revenue Reconciliation Bill of 1996 (the "Bill"),
the revenue portion of President Clinton's budget proposal, was introduced in
the 104th Congress. The Bill, if enacted into law, would have, among other
things, generally denied 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 have applied to the Series A Subordinated
Debentures, the Corporation would not have been 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, depending on certain circumstances, could permit the Corporation to
terminate the Series A Issuer and cause the Series A Subordinated Debentures to
be distributed to the holders of the Series A Capital Securities in exchange
therefor upon liquidation of the Series A Issuer, to shorten the maturity of the
Series A Subordinated Debentures to a date not earlier than January 6, 2017 or
to cause a redemption of the Series A Capital Securities before January 6, 2007.
The Corporation has committed to the Reserve Bank that it will not cause any
such distribution, shortening of the maturity or 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 Subordinated Debentures -- Conditional Right to Shorten
Maturity or Redeem upon a Tax Event or Capital Treatment Event" and
"-- Redemption" in this Prospectus Supplement and "Description of Preferred
Securities -- Redemption or Exchange -- Tax Event Redemption" in the
accompanying Prospectus. See also "Certain Federal Income Tax
Consequences -- Possible Tax Law Changes".
 
                           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 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 Capital Securities and Series A
Common Securities, (ii) using the proceeds from the sale of Series A Capital
Securities and Series A Common Securities to acquire Series A Subordinated
Debentures issued by the Corporation and
 
                                      S-11
<PAGE>   12
 
(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 Capital Securities,
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
Capital Securities. 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
approximately 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").
 
                      FIRST TENNESSEE NATIONAL CORPORATION
 
     The Corporation is a Tennessee corporation incorporated in 1968 and
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
"Bank") and its other subsidiaries, the Corporation provides a broad range of
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
the 50 largest bank holding companies in the United States in asset size and
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
general banking services, mortgage banking, bond broker/agency services, credit
card products, merchant credit card processing, nation-wide check clearing,
integrated check processing solutions, trust services, brokerage, venture
capital, and credit life insurance. Bond broker/agency services provided by the
Bank consist primarily of the sale and underwriting of bank-eligible securities

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 Series A Issuer will use the proceeds from the sale of the Series A
Securities to acquire Series A Subordinated Debentures from the Corporation. The
Corporation intends to use the proceeds from the sale of the Series A
Subordinated Debentures 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 Capital Securities 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.

     (a) As described herein, the sole assets of the Series A Issuer will be
approximately $103,093,000 principal amount of Series A Subordinated Debentures
issued by the Corporation to the Series A Issuer. The Series A Subordinated
Debentures will bear interest at the rate of 8.07% per annum and will mature on
January 6, 2027 (which date may be shortened in certain circumstances as
described under "Certain Terms of Series A Subordinated
Debentures -- Conditional Right to Shorten Maturity or Redeem upon a Tax Event
or Capital Treatment Event" to a date not earlier than January 6, 2017). The
Corporation owns all of the Series A Common Securities of the Series A Issuer.
 
     It is anticipated that the Series A Issuer will not be subject to the
reporting requirements under the Exchange Act.

                              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 Capital Securities 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
Capital Securities, 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 Capital Securities 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 of the
Corporation on the Corporation's balance sheet as a separate line term entitled
"Corporation Obligated Mandatorily Redeemable Capital Securities of Subsidiary
Trust Holding Solely Junior Subordinated Deferrable Interest Debentures of the
Corporation"; (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 CAPITAL SECURITIES
 
GENERAL
 
     The following summary of certain terms and provisions of the Series A
Capital Securities 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. The Series A Capital Securities constitute "Preferred Securities"
as such term is used in the Prospectus. This summary of certain terms and
provisions of the Series A Capital Securities, 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 Capital Securities represent beneficial ownership interests in
the Series A Issuer, and Distributions on each Series A Capital Security will be
payable at the annual rate of 8.07% of the stated Liquidation Amount of $1,000,
payable semi-annually in arrears on January 6 and July 6 of each year, to the
holders of the Series A Capital Securities on the relevant record dates. The
record dates for the Series A Capital Securities will be, for so long as the
Series A Capital Securities 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 Capital Securities 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 Capital Securities will be July 6,
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 Capital Securities 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 10 consecutive semi-annual periods 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, semi-annual
Distributions on the Series A Capital Securities by the Series A Issuer will
also be deferred during any such Extension Period. Distributions to which
holders of the Series A Capital Securities are entitled will accumulate
additional Distributions thereon at the rate per annum of 8.07% thereof,
compounded semi-annually 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
 
                                      S-17
<PAGE>   18
 
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, 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 10
consecutive semi-annual periods 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 8.07%, compounded semi-annually, 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 Capital Securities (the
"Redemption Price"), equal to the aggregate Liquidation Amount of such Series A
Capital Securities plus accumulated and 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 Series A
Subordinated Debentures. If less than all of the Series A Subordinated
Debentures are to be repaid or redeemed on a Redemption Date, then the proceeds
from such repayment or redemption, including any premium paid by the
Corporation, shall be allocated to the redemption pro rata of the Series A
Capital Securities and the Series A Common Securities.
 
     The Corporation has the right to redeem the Series A Subordinated
Debentures (i) on or after January 6, 2007, in whole at any time or in part from
time to time or (ii) at any time, in certain circumstances as described under
"Certain Terms of Series A Subordinated Debentures -- Conditional Right to
Shorten Maturity or Redeem upon a Tax Event or Capital Treatment Event", in
whole (but not in part) within 90 days following the occurrence of a Tax Event
or Capital Treatment Event. A redemption of the Series A Subordinated Debentures
would cause a mandatory redemption of Series A Capital Securities and Series A
Common Securities.
 
                                      S-18

     The Redemption Price, in the case of a redemption under (i) above, shall
equal the following prices expressed in percentages of the Liquidation Amount
together with accrued Distributions to but excluding the Redemption Date. If
redeemed during the 12-month period beginning January 6:

and at 100% on or after January 6, 2017.
 
     The Redemption Price, in the case of a redemption following a Tax Event or
Capital Treatment Event as described under (ii) above, shall be equal to the
aggregate Liquidation Amount of such Series A Capital Securities plus
accumulated and unpaid Distributions thereon to the Redemption Date.
 
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 Capital Securities 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
Capital Securities will not be a taxable event to holders of the Series A
Capital Securities. 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 Capital Securities. See
"Certain Federal Income Tax Consequences -- Distribution of Series A
Subordinated Debentures to Holders of Series A Capital Securities". 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 Capital Securities in
exchange therefor, the Series A Capital Securities will remain outstanding until
the Stated Maturity of the Series A Subordinated Debentures.
 
     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 Capital Securities in exchange therefor upon liquidation of the Series
A Issuer, the Corporation shall continue to have the right to shorten the
maturity of or to redeem the Series A Subordinated Debentures in certain
circumstances upon the occurrence of a Tax Event or a Capital Treatment Event,
as described under "Certain Terms of Series A Subordinated
Debentures -- Conditional Right to Shorten Maturity or Redeem upon a Tax Event
or Capital Treatment Event".
 
LIQUIDATION VALUE
 
     The amount payable on the Series A Capital Securities in the event of any
liquidation of the Series A Issuer is $1,000 per Series A Capital Security plus
accumulated and unpaid Distributions, which amount may be paid in the form of a
distribution of a like amount in Series A Subordinated
 
                                      S-19
<PAGE>   20
 
Debentures, subject to certain exceptions. See "Description of Preferred
Securities -- Liquidation Distribution Upon Termination" in the accompanying
Prospectus.
 
REGISTRATION OF SERIES A CAPITAL SECURITIES
 
     The Series A Capital Securities will be represented by global certificates
registered in the name of DTC or its nominee. Beneficial interests in the Series
A Capital Securities 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 Capital Securities 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 Capital Securities
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 Capital Securities are issued in definitive form, such Series A Capital
Securities will be in denominations of $1,000 and integral multiples thereof and
may be transferred or exchanged at the offices described below.
 
     Payments on Series A Capital Securities represented by a global security
will be made to DTC, as the depositary for the Series A Capital Securities. In
the event Series A Capital Securities are issued in certificated form, the
Liquidation Amount and Distributions will be payable, the transfer of the Series
A Capital Securities will be registrable, and Series A Capital Securities will
be exchangeable for Series A Capital Securities 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 Capital Securities 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
 
                                      S-20
<PAGE>   21
 
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 Capital Securities, 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 8.07% of the
principal amount thereof, payable semi-annually in arrears on January 6 and July
6 of each year (each, an "Interest Payment Date"), commencing July 6, 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 Series A 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 8.07% thereof,
compounded semi-annually from the relevant Interest Payment Date. The term
"interest" as used herein shall include semi-annual interest payments, interest
on semi-annual 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 January 6, 2027 (such
date, as it may be shortened as hereinafter described, the "Stated Maturity").
Such date may be shortened by the Corporation in certain circumstances upon the
occurrence of a Tax Event or a Capital Treatment Event as described under
"-- Conditional Right to Shorten Maturity or Redeem upon a Tax Event or Capital
Treatment Event" to any date not earlier than January 6, 2017. 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.
In the event that the Corporation elects to shorten 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 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
 
                                      S-21
<PAGE>   22
 
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 10 consecutive semi-annual periods 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 8.07%, compounded semi-annually 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 Capital Securities while such series is outstanding) will be
required to recognize income (in the form of original issue discount) 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, 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 10 consecutive semi-annual periods
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
8.07%, compounded semi-annually, 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 New York Stock
Exchange, the Nasdaq National Market or other applicable stock exchange or
automated quotation system on which the Series A Capital
 
                                      S-22
<PAGE>   23
 
Securities 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
("Additional Sums") 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 January 6, 2007, in whole at any
time or in part from time to time or (ii) at any time, in certain circumstances
as described under "Certain Terms of Series A Subordinated
Debentures -- Conditional Right to Shorten Maturity or Redeem upon a Tax Event
or Capital Treatment Event", in whole (but not in part) within 90 days following
the occurrence of a Tax Event or Capital Treatment Event. The proceeds of any
such redemption will be used by the Series A Issuer to redeem the Series A
Securities.
 
     The Redemption Price, in the case of a redemption under (i) above, shall
equal the following prices, expressed in percentages of the principal amount,
together with accrued interest to but excluding the Redemption Date. If redeemed
during the 12-month period beginning January 6:

and at 100% on or after January 6, 2017.
 
     The Redemption Price, in the case of a redemption following a Tax Event or
Capital Treatment Event as described under (ii) above, shall be equal to 100% of
the principal amount plus accrued and unpaid interest thereon to the Redemption
Date.
 
DISTRIBUTION OF SERIES A SUBORDINATED DEBENTURES
 
     As described under "Certain Terms of Series A Capital
Securities -- 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 Capital Securities 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 Capital Securities, the Series A
Subordinated Debentures will initially be issued in the form of one or more

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 Capital Securities. 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 Capital Securities.
 
CONDITIONAL RIGHT TO SHORTEN MATURITY OR REDEEM UPON A TAX EVENT OR CAPITAL
TREATMENT EVENT
 
     If a Tax Event or a Capital Treatment Event occurs and either (i) in the
opinion of counsel to the Corporation experienced in such matters, there would
in all cases, after effecting the termination of the Series A Issuer and the
distribution of the Series A Subordinated Debentures to the holders of the
Series A Capital Securities in exchange therefor, be more than an insubstantial
risk that an Adverse Tax Consequence (as defined in "Risk Factors -- Tax Event
or Capital Treatment Event -- Exchange of Series A Capital Securities for Series
A Subordinated Debentures, Shortening of Maturity of Series A Debentures or
Redemption") would continue to exist, (ii) in the reasonable determination of
the Corporation, there would in all cases, after effecting the termination of
the Series A Issuer and the distribution of the Series A Subordinated Debentures
to the holders of the Series A Capital Securities in exchange therefor upon
liquidation of the Series A Issuer, be 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 Capital Securities as "Tier 1 Capital" (or the equivalent
thereof) or (iii) the Series A Subordinated Debentures are not held by the
Series A Issuer, then the Corporation shall have the right (a) to shorten the
Stated Maturity of the Series A Subordinated Debentures to the minimum extent
required, but in any event to a date not earlier than January 6, 2017 (the
action referred to in this clause (a) being referred to herein as a "Maturity
Advancement"), such that, in the opinion of counsel to the Corporation
experienced in such matters, after advancing the Stated Maturity, interest paid
on the Series A Subordinated Debentures will be deductible for federal income
tax purposes, or (b) if either (x) in the opinion of counsel to the Corporation
experienced in such matters, there would in all cases, after effecting a
Maturity Advancement, be more than an insubstantial risk that an Adverse Tax
Consequence would continue to exist or (y) in the reasonable determination of
the Corporation, there would in all cases, after effecting a Maturity
Advancement, be 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
Capital Securities 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, to redeem the Series A Subordinated
Debentures, in whole but not in part, at any time within 90 days following the
occurrence of the Tax Event or Capital Treatment Event at a Redemption Price
equal to 100% of the principal amount thereof plus accrued and unpaid interest
thereon to the Redemption Date. See "Certain Terms of Series A Capital
Securities -- Liquidation of Series A Issuer and Distribution of Series A
Subordinated Debentures to Holders" and "-- Redemption" and "Certain Terms of
Series A Subordinated Debentures -- General" and "-- Redemption".
 
     Holders of Series A Capital Securities should consult their own tax
advisors regarding the tax consequences to them of a Maturity Advancement.
 
     See "Certain Federal Tax Law Consequences -- Possible Tax Law Changes" for
a discussion of certain legislative proposals that, if adopted, could give rise
to a Tax Event, which may permit the Corporation to shorten the Stated Maturity
of the Series A Subordinated Debentures or cause a redemption of the Series A
Capital Securities prior to January 6, 2007.
 
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 Capital Securities, 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 Capital
Securities as applicable. See "Certain Terms of Series A Capital
Securities -- Registration of Series A Capital Securities.

                      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 Capital 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 Capital 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 Capital 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 Capital Securities in the Direct Action. Except as described
herein, holders of Series A Capital 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 Capital
Securities. This summary only addresses the tax consequences to a person that
acquires Series A Capital Securities 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 Capital Securities, 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 Capital Securities 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 Capital Securities
as capital assets.
 
     The following discussion does not discuss the tax consequences that might
be relevant to persons that are not United States Persons ("non-United States
Persons"). Non-United States Persons should consult their own tax advisors as to
the specific United States tax consequences of the purchase, ownership and
disposition of Series A Capital Securities.
 
     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 Capital Securities. 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 Capital
Securities. 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 Capital Securities 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 CAPITAL SECURITIES, 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 other 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 Capital Securities (a
"Securityholder") will be required to include in its gross income its pro rata
share of the interest income, including premium and 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 contingency that
stated interest will not be timely paid that
 
                                      S-26
<PAGE>   27
 
is "remote" because of the terms of the relevant debt instrument will be ignored
in determining whether a debt instrument is issued with original issue discount
("OID"). As a result of the terms and conditions of the Series A Subordinated
Debentures that prohibit certain payments with respect to the Corporation's
capital stock and indebtedness if the Corporation elects to defer payment of
interest or the Series A Subordinated Debentures, 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 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 Capital Securities 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
Capital Securities.
 
     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 CAPITAL
SECURITIES
 
     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 Capital Securities -- 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 Capital Securities
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 Capital Securities 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 CAPITAL SECURITIES
 
     A Securityholder that sells (including a redemption for cash) Series A
Capital Securities will recognize gain or loss equal to the difference between
its adjusted tax basis in the Series A Capital Securities and the amount
realized on the sale of such Series A Capital Securities. Assuming that the
Corporation does not exercise its option to defer payment of interest on the
Series A Subordinated Debentures, and the Series A Capital Securities are not
considered issued with OID, a
 
                                      S-27
<PAGE>   28
 
Securityholder's adjusted tax basis in the Series A Capital Securities 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 adjusted tax basis in the Series A Capital
Securities 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 Capital Securities 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 Capital Securities have been held for more than one
year.
 
     Should the Corporation exercise its option to defer any payment of interest
on the Series A Subordinated Debentures, the Series A Capital Securities 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
Capital Securities 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 Capital
Securities 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 Capital Securities
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 Capital Securities will be
reported to holders on Form 1099 and mailed to holders of the Series A Capital
Securities by January 31 following each calendar year.
 
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 introduced in
the 104th Congress. The Bill, if enacted into law, would have, among other
things, generally denied 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
 
                                      S-28
<PAGE>   29
 
effective generally for instruments issued on or after December 7, 1995. If this
provision were to have applied to the Series A Subordinated Debentures, the
Corporation would not have been 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, depending on certain
circumstances, could permit the Corporation to terminate the Series A Issuer and
cause the Series A Subordinated Debentures to be distributed to the holders of
the Series A Capital Securities in exchange therefor upon liquidation of the
Series A Issuer, to shorten the maturity of the Series A Subordinated Debentures
to a date not earlier than January 6, 2017 or to cause a redemption of the
Series A Capital Securities before January 6, 2007. 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 Subordinated Debentures -- Redemption" in this
Prospectus Supplement and "Description of Preferred Securities -- Redemption or
Exchange -- Tax Event Redemption" in the accompanying Prospectus. See also
"Certain Federal Income Tax Consequences -- Possible Tax Law Changes".
 
                          CERTAIN ERISA CONSIDERATIONS
 
     Each fiduciary of a pension, profit-sharing or other employee benefit plan
subject to the Employee Retirement Income Security Act of 1974, as amended
("ERISA") (a "Plan"), should consider the fiduciary standards of ERISA in the
context of the Plan's particular circumstances before authorizing an investment
in the Series A Capital Securities. Accordingly, among other factors, the
fiduciary should consider whether the investment would satisfy the prudence and
diversification requirements of ERISA and would be consistent with the documents
and instruments governing the Plan.
 
     Section 406 of ERISA and Section 4975 of the Code prohibit Plans, as well
as individual retirement accounts and Keogh plans subject to Section 4975 of the
Code (also "Plans"), from engaging in certain transactions involving "plan
assets" with persons who are "parties in interest" under ERISA or "disqualified
persons" under the Code ("Parties in Interest") with respect to such Plan. A
violation of these "prohibited transaction" rules may result in an excise tax or
other liabilities under ERISA and/or Section 4975 of the Code for such persons,
unless exemptive relief is available under an applicable statutory or
administrative exemption. Employee benefit plans that are governmental plans (as
defined in Section 3(32) of ERISA), certain church plans (as defined in Section
3(33) of ERISA) and foreign plans (as described in Section 4(b)(5) of ERISA) are
not subject to the requirements of ERISA or Section 4975 of the Code;
governmental plans may be subject to similar provisions under applicable state
laws.
 
     Under a regulation (the "Plan Assets Regulation") issued by the U.S.
Department of Labor (the "DOL"), the assets of the Series A Issuer would be
deemed to be "plan assets" of a Plan for purposes of ERISA and Section 4975 of
the Code if "plan assets" of the Plan were used to acquire an equity interest in
the Series A Issuer and no exception were applicable under the Plan Assets
Regulation. An "equity interest" is defined under the Plan Assets Regulation as
any interest in an entity other than an instrument which is treated as
indebtedness under applicable local law and which has no substantial equity
features and specifically includes a beneficial interest in a trust.
 
                                      S-29
<PAGE>   30
 
     Pursuant to an exception contained in the Plan Assets Regulation, the
assets of the Series A Issuer would not be deemed to be "plan assets" of
investing Plans if, immediately after the most recent acquisition of any equity
interest in the Series A Issuer, less than 25% of the value of each class of
equity interests in the Series A Issuer were held by Plans, other employee
benefit plans not subject to ERISA or Section 4975 of the Code (such as
governmental, church and foreign plans), and entities holding assets deemed to
be "plan assets" of any Plan (collectively, "Benefit Plan Investors"), or if the
Series A Capital Securities were "publicly-offered securities" for purposes of
the Plan Assets Regulation. No assurance can be given that the value of the
Series A Capital Securities held by Benefit Plan Investors will be less than 25%
of the total value of such Series A Capital Securities at the completion of the
initial offering or thereafter, and no monitoring or other measures will be
taken with respect to the satisfaction of the conditions to this exception. In
addition, no assurance can be given that the Series A Capital Securities would
be considered to be "publicly-offered securities" under the Plan Assets
Regulation. All of the Series A Common Securities will be purchased and
initially held by the Corporation.
 
     Certain transactions involving the Series A Issuer could be deemed to
constitute direct or indirect prohibited transactions under ERISA and Section
4975 of the Code with respect to a Plan if the Series A Capital Securities were
acquired with "plan assets" of such Plan and the assets of the Series A Issuer
were deemed to be "plan assets" of Plans investing in the Series A Issuer. For
example, if the Corporation is a Party in Interest with respect to an investing
Plan (either directly or by reason of its ownership of the Bank or other
subsidiaries), extensions of credit between the Corporation and the Series A
Issuer (as represented by the Series A Subordinated Debentures and the Series A
Guarantee) would likely be prohibited by Section 406(a)(1)(B) of ERISA and
Section 4975(c)(1)(B) of the Code, unless exemptive relief were available under
an applicable administrative exemption (see below). In addition, if the
Corporation were considered to be a fiduciary with respect to the Series A
Issuer as a result of certain powers it holds (such as the powers to remove and
replace the Property Trustee and the Administrative Trustees), the optional
redemption or acceleration of the Series A Subordinated Debentures could be
considered to be prohibited transactions under Section 406(b) of ERISA and
Section 4975(c)(1)(E) of the Code.
 
     The DOL has issued five prohibited transaction class exemptions ("PTCEs")
that may provide exemptive relief if required for direct or indirect prohibited
transactions that may arise from the purchase or holding of the Series A Capital
Securities if assets of the Series A Issuer were deemed to be "plan assets" of
Plans investing in the Series A Issuer as described above. Those class
exemptions are PTCE 96-23 (for certain transactions determined by in-house asset
managers), PTCE 95-60 (for certain transactions involving insurance company
general accounts), PTCE 91-38 (for certain transactions involving bank
collective investment funds), PTCE 90-1 (for certain transactions involving
insurance company separate accounts), and PTCE 84-14 (for certain transactions
determined by independent qualified asset managers).
 
     Because the Series A Capital Securities may be deemed to be equity
interests in the Series A Issuer for purposes of applying ERISA and Section 4975
of the Code, the Series A Capital Securities may not be purchased or held by any
Plan, any entity whose underlying assets include "plan assets" by reason of any
Plan's investment in the entity (a "Plan Asset Entity") or any person investing
"plan assets" of any Plan, unless such purchaser or holder is eligible for the
exemptive relief available under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or
another applicable exemption. Any purchaser or holder of the Series A Capital
Securities or any interest therein will be deemed to have represented by its
purchase and holding thereof that it either (a) is not a Plan or a Plan Asset
Entity and is not purchasing such securities on behalf of or with "plan assets"
of any Plan or (b) is eligible for the exemptive relief available under PTCE
96-23, 95-60, 91-38, 90-1 or 84-14 or another applicable exemption with respect
to such purchase or holding. If a purchaser or holder of the Series A Capital
Securities that is a Plan or a Plan Asset Entity elects to rely on an exemption
other than PTCE 96-23, 95-60, 91-38, 90-1 or 84-14, the Corporation and the
Series A Issuer may require a satisfactory opinion of counsel or other evidence
with respect to the availability of such exemption for such purchase and
holding.
 
                                      S-30
<PAGE>   31
 
     Due to the complexity of these rules and the penalties that may be imposed
upon persons involved in non-exempt prohibited transactions, it is particularly
important that fiduciaries or other persons considering purchasing the Series A
Capital Securities on behalf of or with "plan assets" of any Plan consult with
their counsel regarding the potential consequences if the assets of the Series A
Issuer were deemed to be "plan assets" and the availability of exemptive relief
under PTCE 96-23, 95-60, 91-38, 90-1 or 84-14 or any other applicable exemption.

     Subject to the terms and conditions of the Underwriting Agreement, the
Corporation and the Series A Issuer have agreed that the Series A Issuer will

     Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all the Series A Capital
Securities offered hereby, if any are taken. In the event of a default by an
Underwriter, the Underwriting Agreement provides that, in certain circumstances,
the purchase commitments of the nondefaulting Underwriters may be increased or
the Underwriting Agreement may be terminated.
 
     The Underwriters propose to offer the Series A Capital Securities in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus Supplement and in part to certain dealers at such
price less a concession of $6.00 per Series A Capital Security. The Underwriters
may allow, and such dealers may reallow, a discount not in excess of $2.50 per
Series A Capital Security to certain brokers and other dealers. After the Series
A Capital Securities are released for sale to the public, the offering price and
other selling terms may from time to time be varied by the Underwriters.
 
     In view of the fact that the proceeds from the sale of the Series A Capital
Securities 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 $10.00 per Series A Capital
Security for the accounts of the several Underwriters.
 
     Because the National Association of Securities Dealers, Inc. ("NASD") is
expected to view the Series A Capital Securities offered hereby as interests in
a direct participation program, the offering is being made in compliance with
Rule 2810 of the NASD's Conduct Rules. Offers and sales of Series A Capital
Securities will be made only to (i) "qualified institutional buyers", as defined
in Rule 144A under the Securities Act of 1933, as amended (the "Act"); (ii)
institutional "accredited investors", as defined in Rule 501(a)(1)-(3) of
Regulation D under the Act or (iii) individual investors for whom an investment
in non-convertible investment grade preferred securities is appropriate. The
Underwriters may not confirm sales to any accounts over which they exercise
discretionary authority without the prior written approval of the transaction by
the customer.
 
     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 Capital Securities, as determined by the Underwriters, and (ii) the
closing date, they will not offer, sell, contract to sell or otherwise dispose
of any Series A Capital 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 Capital Securities, 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 Corpora-

tion, without the prior written consent of the Underwriters, except for the
Series A Capital Securities offered in connection with this offering.
 
     Prior to this offering, there has been no public market for the Series A
Capital Securities. The Underwriters have advised the Corporation that they
intend to make a market in the Series A Capital Securities, but 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 Capital Securities.
 
     The Corporation and the Series A Issuer have agreed to indemnify the
several Underwriters against, or contribute to payments that the Underwriters
may be required to make in respect of, certain liabilities, including
liabilities under the Act.
 
     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.
 
                             VALIDITY OF SECURITIES
 
     Certain matters of Delaware law relating to the validity of the Series A
Capital Securities, the enforceability of the Trust Agreement and the formation
of the Series A Issuer will be passed upon by Richards, Layton & Finger, special
Delaware counsel to the Corporation and the Series A Issuer. The validity of the
Series A Guarantee and the Series A Subordinated Debentures will be passed upon
for the Corporation by Sullivan & Cromwell, New York, New York and for the
Underwriters by Simpson Thacher & Bartlett (a partnership which includes
professional corporations), New York, New York. 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. 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. Certain matters relating to United States federal income tax
considerations described in this Prospectus Supplement will be passed upon for
the Corporation by Sullivan & Cromwell. At December 2, 1996, Mr. Johnson
beneficially owned approximately 73,700 shares of the Corporation's common
stock.

                      FIRST TENNESSEE NATIONAL CORPORATION
 
     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 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,
notes and schedules filed as a part thereof or incorporated by reference
therein, which may be inspected at the public reference facilities of the
Commission at the addresses set forth above or, with respect to certain of the

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.

other than holding as trust assets the Corresponding Junior Subordinated
Debentures of the Corporation and issuing the Trust Securities. See "The

                      FIRST TENNESSEE NATIONAL CORPORATION
 
     The Corporation is a Tennessee corporation incorporated in 1968 and
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
"Bank") and its other subsidiaries, the Corporation provides a broad range of
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
the 50 largest bank holding companies in the United States in asset size and
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
general banking services, mortgage banking, bond broker/agency services, credit
card products, merchant credit card processing, nation-wide check clearing,
integrated check processing solutions, trust services, brokerage, venture
capital, and credit life insurance. Bond broker/agency services provided by the
Bank consist primarily of the sale and underwriting of bank-eligible securities
and mortgage loans and providing advisory services to other financial

                       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, and subject to regulation
by, the FDIC. The Subsidiary Banks are subject to various requirements
 
                                        5
<PAGE>   39
 
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 restrictions on the Subsidiary Banks'
purchases of or investments in the securities of and purchases
 
                                        6
<PAGE>   40
 
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.
 
     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
 
                                        7
<PAGE>   41
 
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 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
 
                                        8
<PAGE>   42
 
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 limita-
 
                                        9
<PAGE>   43
 
tion 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, and the record
dates for any interest payable on any Interest Payment Date (the "Regular Record
 
                                       12
<PAGE>   46
 
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 Corporation anticipates that the following
provisions will generally apply to depositary arrangements.
 
                                       14
<PAGE>   48
 
     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.
 
     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
 
                                       15
<PAGE>   49
 
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 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
 
                                       16
<PAGE>   50
 
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
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 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 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
 
                                       17
<PAGE>   51
 
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 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.
 
                                       18
<PAGE>   52
 
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 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.
 
                                       19
<PAGE>   53
 
     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
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
 
                                       20
<PAGE>   54
 
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 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 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 subordina-
 
                                       22
<PAGE>   56
 
tion 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.
 
                                       23
<PAGE>   57
 
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% ownership 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
 
                                       24
<PAGE>   58
 
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 "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
 
                                       25
<PAGE>   59
 
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 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.
 
                                       26
<PAGE>   60
 
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 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
 
                                       27
<PAGE>   61
 
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 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
 
                                       28
<PAGE>   62
 
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
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.
 
                                       29
<PAGE>   63
 
     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.
 
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
 
                                       30
<PAGE>   64
 
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
 
          (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
 
                                       31
<PAGE>   65
 
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
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
 
                                       32
<PAGE>   66
 
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, 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
 
                                       33
<PAGE>   67
 
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
 
                                       34
<PAGE>   68
 
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, 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.
 
                                       35
<PAGE>   69
 
     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.
 
                                       36
<PAGE>   70
 
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 courses 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 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
 
                                       37
<PAGE>   71
 
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 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 disburse-
 
                                       38
<PAGE>   72
 
ments 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 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
 
                                       39
<PAGE>   73
 
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.
 
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
 
                                       40
<PAGE>   74
 
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>   76
 
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>   77
 
     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,
Mr. Johnson beneficially owned approximately 73,700 shares of the Corporation's
common stock.
