    AMCORE Capital Trust I, a trust formed under the laws of the State of
Delaware (the "Trust"), hereby offers, upon the terms and subject to the
conditions set forth in this Prospectus (as the same may be amended or
supplemented from time to time, the "Prospectus") and in the accompanying Letter
of Transmittal (which together constitute the "Exchange Offer"), to exchange up
to $40,000,000 aggregate Liquidation Amount of its 9.35% Series B Capital
Securities (the "New Capital Securities") for a like Liquidation Amount of its
outstanding 9.35% Series A Capital Securities (the "Old Capital Securities"), of
which $40,000,000 aggregate Liquidation Amount is outstanding. Pursuant to the
Exchange Offer, AMCORE Financial, Inc., a Nevada corporation (the
"Corporation"), is also offering to exchange (i) its guarantee of payments of
cash distributions and payments on liquidation of the Trust or redemption of the
Old Capital Securities (the "Old Guarantee") for a like guarantee in respect of
the New Capital Securities (the "New Guarantee") and (ii) all of its 9.35%
Series B Junior Subordinated Deferrable Interest Debentures due June 15, 2027
(the "Old Junior Subordinated Debentures") for a like aggregate principal amount
of its 9.35% Series A Junior Subordinated Deferrable Interest Debentures due
June 15, 2027 (the "New Junior Subordinated Debentures"). The Old Capital
Securities, the Old Guarantee and the Old Junior Subordinated Debentures are
collectively referred to herein as the "Old Securities" and the New Capital
Securities, the New Guarantee and the New Junior Subordinated Debentures are
collectively referred to herein as the "New Securities."
 
    The terms of the New Securities are identical in all material respects to
the respective terms of the Old Securities, except that (i) the New Securities
have been registered under the Securities Act of 1933, as amended (the
"Securities Act"), and therefore will not be subject to certain restrictions on
transfer applicable to the Old Securities, (ii) the New Capital Securities will
not contain the $100,000 minimum Liquidation Amount transfer restriction, (iii)
the New Capital Securities will not provide for any increase in the distribution
rate thereon, (iv) the New Junior Subordinated Debentures will not contain the
$100,000 minimum principal amount transfer restriction and (v) the New Junior
Subordinated Debentures will not provide for any increase in the interest rate
thereon. See "Description of New Securities" and "Description of Old
Securities." The New Capital Securities are being offered for exchange in order
to satisfy certain obligations of the Corporation and the Trust under the
Registration Rights Agreement, dated as of March 25, 1997 (the "Registration
Rights Agreement"), among the Corporation, the Trust and the Initial Purchaser
(as defined herein). In the event that the Exchange Offer is consummated, any
Old Capital Securities which remain outstanding after consummation of the
Exchange Offer and the New Capital Securities issued in the Exchange Offer will
vote together as a single class for purposes of determining whether holders of
the requisite percentage in outstanding Liquidation Amount thereof have taken
certain actions or exercised certain rights under the Declaration.

    This Prospectus and the Letter of Transmittal are first being mailed to all
holders of Old Capital Securities on          , 1997.

           ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

(continued from previous page)
 
     The New Capital Securities and the Old Capital Securities (collectively,
the "Capital Securities") represent beneficial interests in the assets of the
Trust. The Corporation is the owner of all of the beneficial interests
represented by common securities of the Trust (the "Common Securities," and
together with the Capital Securities, the "Trust Securities"). The First
National Bank of Chicago is the Property Trustee of the Trust. The Trust exists
for the sole purpose of issuing the Trust Securities and investing the proceeds
thereof in the Junior Subordinated Debentures (as defined herein). The Junior
Subordinated Debentures will mature on June 15, 2027 (the "Stated Maturity
Date"). The Capital Securities will have a preference over the Common Securities
under certain circumstances with respect to cash distributions and amounts
payable on liquidation, redemption or otherwise. See "Description of New
Securities -- Description of New Capital Securities -- Subordination of Common
Securities."
 
     As used herein, (i) the "Indenture" means the Indenture, dated as of March
25, 1997, as amended and supplemented from time to time, between the Corporation
and The First National Bank of Chicago, as Debenture Trustee (the "Debenture
Trustee"), (ii) the "Declaration" means the Amended and Restated Declaration of
Trust relating to the Trust among the Corporation, as Sponsor, The First
National Bank of Chicago, as Property Trustee (the "Property Trustee"), First
Chicago Delaware Inc., as Delaware Trustee, (the "Delaware Trustee"), and the
Administrative Trustees named therein (collectively, with the Property Trustee
and Delaware Trustee, the "Issuer Trustees"). In addition, as the context may
require, unless otherwise expressly stated, (i) the term "Capital Securities"
includes the Old Capital Securities and the New Capital Securities, (ii) the
term "Trust Securities" includes the Capital Securities and the Common
Securities, (iii) the term "Junior Subordinated Debentures" includes the Old
Junior Subordinated Debentures and the New Junior Subordinated Debentures and
(iv) the term "Guarantee" includes the Old Guarantee and the New Guarantee.
 
     Holders of the New Capital Securities will be entitled to receive
cumulative cash distributions arising from the payment of interest on the New
Junior Subordinated Debentures, accruing from March 25, 1997 and payable
semi-annually in arrears on June 15 and December 15 of each year, commencing
June 15, 1997, at the annual rate of 9.35% of the Liquidation Amount of $1,000
per New Capital Security ("Distributions"). The Corporation will have the right
to defer payments of interest on the Junior Subordinated Debentures at any time
and 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 shall end on a date other than an Interest
Payment Date (as defined herein) or extend beyond the Stated Maturity Date. Upon
the termination of any such Extension Period and the payment of all amounts then
due, the Corporation may elect to begin a new Extension Period, subject to the
requirements set forth in the Indenture. If and for so long as interest payments
on the Junior Subordinated Debentures are so deferred, Distributions on the
Trust 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 (which
includes common and preferred stock) or to make any payment with respect to debt
securities of the Corporation that rank pari passu with or junior to the Junior
Subordinated Debentures. During an Extension Period, interest on the Junior
Subordinated Debentures will continue to accrue (and the amount of Distributions
to which holders of the Trust Securities are entitled will continue to
accumulate) at the rate of 9.35% per annum, compounded semi-annually, and
holders of Trust Securities will be required to accrue such deferred interest
income for United States federal income tax purposes prior to receipt of cash
payments attributable to such interest income. See "Description of New
Securities -- Description of New Junior Subordinated Debentures -- Option to
Extend Interest Payment Date" and "Certain Federal Income Tax Considerations --
Interest Income and Original Issue Discount."
 
     Through the Guarantee, the guarantee agreement of the Corporation relating
to the Common Securities (the "Common Guarantee"), the Declaration, the Junior
Subordinated Debentures and the Indenture, taken together, the Corporation has
guaranteed or will guarantee, as the case may be, fully, irrevocably and
unconditionally, all of the Trust's obligations under the Trust Securities. See
"Relationship Among the New Capital Securities, the New Junior Subordinated
Debentures and the New Guarantee -- Full and Unconditional Guarantee." The Old
Guarantee and the Common Guarantee guarantees, and the New Guarantee will
 
                                        2

guarantee, payments of Distributions and payments on liquidation or redemption
of the Trust Securities, but in each case only to the extent that the Trust
holds funds on hand legally available therefor and has failed to make such
payments, as described herein. See "Description of New Securities -- Description
of New Guarantee." If the Corporation fails to make a required payment on the
Junior Subordinated Debentures, the Trust will not have sufficient funds to make
the related payments, including Distributions, on the Trust Securities. The
Guarantee and the Common Guarantee will not cover any such payment when the
Trust does not have sufficient funds on hand legally available therefor. In such
event, a holder of Capital Securities may institute a legal proceeding directly
against the Corporation to enforce its rights in respect of such payment. See
"Description of New Securities -- Description of New Junior Subordinated
Debentures -- Enforcement of Certain Rights By Holders of New Capital
Securities." The obligations of the Corporation under the Guarantee, the Common
Guarantee and the Junior Subordinated Debentures will be subordinate and junior
in right of payment to all Senior Indebtedness (as defined in "Description of
New Securities -- Description of New Junior Subordinated Debentures --
Subordination").
 
     The Trust Securities will be subject to mandatory redemption in a Like
Amount (as defined herein), (i) in whole but not in part, on the Stated Maturity
Date upon repayment of the Junior Subordinated Debentures at a redemption price
equal to the principal amount of, plus accrued and unpaid interest on, the
Junior Subordinated Debentures (the "Maturity Redemption Price"), (ii) in whole
but not in part, at any time before March 1, 2007 (the "Initial Optional
Prepayment Date"), contemporaneously with the optional prepayment by the
Corporation of the Junior Subordinated Debentures, upon the occurrence and
continuation of a Special Event (as defined herein) at a redemption price equal
to the Special Event Prepayment Price (as defined herein) (the "Special Event
Redemption Price"), and (iii) in whole or in part, on or after the Initial
Optional Prepayment Date, contemporaneously with the optional prepayment by the
Corporation of the Junior Subordinated Debentures, at a redemption price equal
to the Optional Prepayment Price (as defined herein) (the "Optional Redemption
Price"). Any of the Maturity Redemption Price, the Special Event Redemption
Price and the Optional Redemption Price may be referred to herein as the
"Redemption Price." See "Description of New Securities -- Description of New
Capital Securities -- Redemption."
 
     Subject to the Corporation having received prior approval of the Board of
Governors of the Federal Reserve System (the "Federal Reserve"), if then
required under applicable capital guidelines or policies of the Federal Reserve,
the Junior Subordinated Debentures will be prepayable prior to the Stated
Maturity Date at the option of the Corporation (i) on or after the Initial
Optional Prepayment Date, in whole or in part, at a prepayment price (the
"Optional Prepayment Price") equal to 104.675% of the principal amount thereof
on the Initial Optional Prepayment Date, declining ratably on each March 1
thereafter to 100% on or after March 1, 2017, plus accrued and unpaid interest
thereon to the date of prepayment, or (ii) at any time before the Initial
Optional Prepayment Date, in whole but not in part, upon the occurrence and
continuation of a Special Event, at a prepayment price (the "Special Event
Prepayment Price") equal to the greater of (a) 100% of the principal amount
thereof or (b) the sum, as determined by a Quotation Agent (as defined herein),
of the present values of the principal amount and premium payable as part of the
Optional Prepayment Price with respect to an optional redemption of such Junior
Subordinated Debentures on the Initial Optional Prepayment Date, together with
scheduled payments of interest from the prepayment date to the Initial Optional
Prepayment Date, in each case, discounted to the prepayment date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Adjusted Treasury Rate (as defined herein) plus, in either case, accrued
and unpaid interest thereon to the date of prepayment. Either of the Optional
Prepayment Price or the Special Event Prepayment Price may be referred to herein
as the "Prepayment Price." See "Description of New Securities -- Description of
New Junior Subordinated Debentures -- Optional Prepayment" and "-- Special Event
Prepayment."
 
     The Corporation, as the holder of the outstanding Common Securities, will
have the right at any time to terminate the Trust and cause a Like Amount of the
Junior Subordinated Debentures to be distributed to the holders of the Trust
Securities in liquidation of the Trust, subject to (i) the Corporation having
received an opinion of counsel to the effect that such distribution will not be
a taxable event to holders of the Capital Securities and (ii) the prior approval
of the Federal Reserve, if then required under applicable capital
 
                                        3

(continued from previous page)
 
guidelines or policies of the Federal Reserve. Unless the Junior Subordinated
Debentures are distributed to the holders of the Trust Securities, in the event
of a liquidation of the Trust as described herein, after satisfaction of
liabilities to creditors of the Trust as required by applicable law, the holders
of the Trust Securities generally will be entitled to receive a Liquidation
Amount of $1,000 per Trust Security plus accumulated and unpaid Distributions
thereon to the date of payment. See "Description of New Securities --
Description of New Capital Securities -- Liquidation of the Trust and
Distribution of Junior Subordinated Debentures" and "Certain Federal Income Tax
Considerations -- Distribution of Junior Subordinated Debentures to Holders of
Capital Securities."
 
     The Trust is making the Exchange Offer of the New Capital Securities in
reliance on the position of the staff of the Division of Corporation Finance of
the Securities and Exchange Commission (the "Commission") as set forth in
certain interpretive letters addressed to third parties in other transactions.
However, neither the Corporation nor the Trust has sought its own interpretive
letter and there can be no assurance that the staff of the Division of
Corporation Finance of the Commission would make a similar determination with
respect to the Exchange Offer as it has in such interpretive letters to third
parties. Based on these interpretations by the staff of the Division of
Corporation Finance of the Commission, and subject to the two immediately
following sentences, the Corporation and the Trust believe that New Capital
Securities issued pursuant to this Exchange Offer in exchange for Old Capital
Securities may be offered for resale, resold and otherwise transferred by a
holder thereof (other than a holder who is a broker-dealer) without further
compliance with the registration and prospectus delivery requirements of the
Securities Act, provided that such New Capital Securities are acquired in the
ordinary course of such holder's business and that such holder is not
participating, and has no arrangement or understanding with any person to
participate, in a distribution (within the meaning of the Securities Act) of
such New Capital Securities. However, any holder of Old Capital Securities who
is an "affiliate" of the Corporation or the Trust or who intends to participate
in the Exchange Offer for the purpose of distributing New Capital Securities, or
any broker-dealer who purchased Old Capital Securities from the Trust to resell
pursuant to Rule 144A under the Securities Act ("Rule 144A") or any other
available exemption under the Securities Act, (a) will not be able to rely on
the interpretations of the staff of the Division of Corporation Finance of the
Commission set forth in the above-mentioned interpretive letters, (b) will not
be permitted or entitled to tender such Old Capital Securities in the Exchange
Offer and (c) must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any sale or other transfer
of such Old Capital Securities unless such sale is made pursuant to an exemption
from such requirements. In addition, as described below, if any broker-dealer
holds Old Capital Securities acquired for its own account as a result of
market-making or other trading activities and exchanges such Old Capital
Securities for New Capital Securities, then such broker-dealer must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resales of such New Capital Securities.
 
     Each holder of Old Capital Securities who wishes to exchange Old Capital
Securities for New Capital Securities in the Exchange Offer will be required to
represent that (i) it is not an "affiliate" of the Corporation or the Trust,
(ii) any New Capital Securities to be received by it are being acquired in the
ordinary course of its business, (iii) it has no arrangement or understanding
with any person to participate in a distribution (within the meaning of the
Securities Act) of such New Capital Securities, and (iv) if such holder is not a
broker-dealer, such holder is not engaged in, and does not intend to engage in,
a distribution (within the meaning of the Securities Act) of such New Capital
Securities. In addition, the Corporation and the Trust may require such holder,
as a condition to such holder's eligibility to participate in the Exchange
Offer, to furnish to the Corporation and the Trust (or an agent thereof) in
writing information as to the number of "beneficial owners" (within the meaning
of Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) on behalf of whom such holder holds the Capital Securities to
be exchanged in the Exchange Offer. Each broker-dealer that receives New Capital
Securities for its own account pursuant to the Exchange Offer must acknowledge
that it acquired the Old Capital Securities for its own account as the result of
market-making activities or other trading activities and must agree that it will
deliver a prospectus meeting the requirements of the Securities Act in
connection with any resale of such New Capital Securities. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will
 
                                        4

(continued from previous page)
 
not be deemed to admit that it is an "underwriter" within the meaning of the
Securities Act. Based on the position taken by the staff of the Division of
Corporation Finance of the Commission in the interpretive letters referred to
above, the Corporation and the Trust believe that broker-dealers who acquired
Old Capital Securities for their own accounts, as a result of market-making
activities or other trading activities ("Participating Broker-Dealers"), may
fulfill their prospectus delivery requirements with respect to the New Capital
Securities received upon exchange of such Old Capital Securities (other than Old
Capital Securities which represent an unsold allotment from the original sale of
the Old Capital Securities) with a prospectus meeting the requirements of the
Securities Act, which may be the prospectus prepared for an exchange offer so
long as it contains a description of the plan of distribution with respect to
the resale of such New Capital Securities. Accordingly, this Prospectus, as it
may be amended or supplemented from time to time, may be used by a Participating
Broker-Dealer during the period referred to below in connection with resales of
New Capital Securities received in exchange for Old Capital Securities where
such Old Capital Securities were acquired by such Participating Broker-Dealer
for its own account as a result of market-making or other trading activities.
Subject to certain provisions set forth in the Registration Rights Agreement,
the Corporation and the Trust have agreed that this Prospectus, as it may be
amended or supplemented from time to time, may be used by a Participating
Broker-Dealer in connection with resales of such New Capital Securities for a
period ending 90-days after the Expiration Date (as defined herein) (subject to
extension under certain limited circumstances described below) or, if earlier,
when all such New Capital Securities have been disposed of by such Participating
Broker-Dealer. See "Plan of Distribution." However, a Participating
Broker-Dealer who intends to use this Prospectus in connection with the resale
of New Capital Securities received in exchange for Old Capital Securities
pursuant to the Exchange Offer must notify the Corporation or the Trust, or
cause the Corporation or the Trust to be notified, on or prior to the Expiration
Date, that it is a Participating Broker-Dealer. Such notice may be given in the
space provided for that purpose in the Letter of Transmittal or may be delivered
to the Exchange Agent at one of the addresses set forth herein under "The
Exchange Offer -- Exchange Agent." Any Participating Broker-Dealer who is an
"affiliate" of the Corporation or the Trust may not rely on such interpretive
letters and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any resale transaction.
See "The Exchange Offer -- Resales of New Capital Securities."
 
     In that regard, each Participating Broker-Dealer who surrenders Old Capital
Securities pursuant to the Exchange Offer will be deemed to have agreed, by
execution of the Letter of Transmittal, that, upon receipt of notice from the
Corporation or the Trust of the occurrence of any event or the discovery of any
fact which makes any statement contained or incorporated by reference in this
Prospectus untrue in any material respect or which causes this Prospectus to
omit to state a material fact necessary in order to make the statements
contained or incorporated by reference herein, in light of the circumstances
under which they were made, not misleading or of the occurrence of certain other
events specified in the Registration Rights Agreement, such Participating
Broker-Dealer will suspend the sale of New Capital Securities (or the New
Guarantee or the New Junior Subordinated Debentures, as applicable) pursuant to
this Prospectus until the Corporation or the Trust has amended or supplemented
this Prospectus to correct such misstatement or omission and has furnished
copies of the amended or supplemented Prospectus to such Participating
Broker-Dealer or the Corporation or the Trust has given notice that the sale of
the New Capital Securities (or the New Guarantee or the New Junior Subordinated
Debentures, as applicable) may be resumed, as the case may be. If the
Corporation or the Trust gives such notice to suspend the sale of the New
Capital Securities (or the New Guarantee or the New Junior Subordinated
Debentures, as applicable), it shall extend the 90-day period referred to above
during which Participating Broker-Dealers are entitled to use this Prospectus in
connection with the resale of New Capital Securities by the number of days
during the period from and including the date of the giving of such notice to
and including the date when Participating Broker-Dealers shall have received
copies of the amended or supplemented Prospectus necessary to permit resales of
the New Capital Securities or to and including the date on which the Corporation
or the Trust has given notice that the sale of New Capital Securities (or the
New Guarantee or the New Junior Subordinated Debentures, as applicable) may be
resumed, as the case may be.

(continued from previous page)
 
     Prior to the Exchange Offer, there has been only a limited secondary market
and no public market for the Old Capital Securities. The New Capital Securities
will be a new issue of securities for which there currently is no market.
Although the Initial Purchaser has informed the Corporation and the Trust that
it currently intends to make a market in the New Capital Securities, it is not
obligated to do so, and any such market making may be discontinued at any time
without notice. Accordingly, there can be no assurance as to the development or
liquidity of any market for the New Capital Securities. The Corporation and the
Trust currently do not intend to apply for listing of the New Capital Securities
on any securities exchange or for quotation through the National Association of
Securities Dealers Automated Quotation System.
 
     Any Old Capital Securities not tendered and accepted in the Exchange Offer
will remain outstanding and will be entitled to all the same rights and will be
subject to the same limitations applicable thereto under the Declaration (except
for those rights which terminate upon consummation of the Exchange Offer).
Following consummation of the Exchange Offer, the holders of Old Capital
Securities will continue to be subject to all of the existing restrictions upon
transfer thereof and neither the Corporation nor the Trust will have any further
obligation to such holders (other than under certain limited circumstances) to
provide for registration under the Securities Act of the Old Capital Securities
held by them. To the extent that Old Capital Securities are tendered and
accepted in the Exchange Offer, a holder's ability to sell untendered Old
Capital Securities could be adversely affected. See "Risk Factors --
Consequences of a Failure to Exchange Old Capital Securities."
 
     THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF OLD CAPITAL SECURITIES ARE URGED TO READ THIS PROSPECTUS
AND THE RELATED LETTER OF TRANSMITTAL CAREFULLY BEFORE DECIDING WHETHER TO
TENDER THEIR OLD CAPITAL SECURITIES PURSUANT TO THE EXCHANGE OFFER.
 
     Old Capital Securities may be tendered for exchange on or prior to 5:00
p.m., New York City time, on             , 1997 (such time on such date being
hereinafter called the "Expiration Date"), unless the Exchange Offer is extended
by the Corporation or the Trust (in which case the term "Expiration Date" shall
mean the latest date and time to which the Exchange Offer is extended). Tenders
of Old Capital Securities may be withdrawn at any time on or prior to the
Expiration Date. The Exchange Offer is not conditioned upon any minimum
Liquidation Amount of Old Capital Securities being tendered for exchange.
However, the Exchange Offer is subject to certain events and conditions which
may be waived by the Corporation or the Trust and to the terms and provisions of
the Registration Rights Agreement. Old Capital Securities may be tendered in
whole or in part having an aggregate Liquidation Amount of not less than
$100,000 (100 Capital Securities) or any integral multiple of $1,000 Liquidation
Amount (one Capital Security) in excess thereof. The Corporation has agreed to
pay all expenses of the Exchange Offer. See "The Exchange Offer -- Fees and
Expenses." Holders of the Old Capital Securities whose Old Capital Securities
are accepted for exchange will not receive Distributions on such Old Capital
Securities and will be deemed to have waived the right to receive any
Distributions on such Old Capital Securities accumulated from and after March
25, 1997. See "The Exchange Offer -- Distributions on New Capital Securities."
 
     Neither the Corporation nor the Trust will receive any cash proceeds from
the issuance of the New Capital Securities offered hereby. No dealer-manager is
being used in connection with this Exchange Offer. See "Use of Proceeds" and
"Plan of Distribution."

operations and is not engaged in and does not propose to engage in any activity
other than holding as trust assets the Junior Subordinated Debentures and
issuing the Trust Securities. See "The Trust" and "Description of New

file reports under the Exchange Act with the Commission.

                             AMCORE CAPITAL TRUST I
 
     The Trust is a statutory business trust formed under Delaware law pursuant
to (i) the declaration executed by the Corporation, as Sponsor, The First
National Bank of Chicago, as Property Trustee, First Chicago Delaware Inc., as

(ii) the filing of a certificate of trust with the Delaware Secretary of State

Property Trustee, the Delaware Trustee and three individual Administrative
Trustees, who are employees or officers of, or affiliated with, the Corporation.
The Trust exists for the exclusive purposes of (i) issuing and selling the Trust
Securities, (ii) using the proceeds from the sale of the Trust Securities to
acquire the Junior Subordinated Debentures issued by the Corporation, and (iii)
engaging in only those other activities necessary, advisable or incidental

the Junior Subordinated Debentures will be the sole assets of the Trust, and
payments under the Junior Subordinated Debentures will be the sole revenue of
the Trust. All of the Common Securities are owned by the Corporation.

Resales of New Capital
Securities....................   The Corporation and the Trust are making the
                                 Exchange Offer in reliance on the position of
                                 the staff of the Division of Corporation
                                 Finance of the Commission as set forth in
                                 certain interpretive letters addressed to third
                                 parties in other transactions. However, neither
                                 the Corporation nor the Trust has sought its
                                 own interpretive letter and there can be no
                                 assurance that the staff of the Division of
                                 Corporation Finance of the Commission would
                                 make a similar determination with respect to
                                 the Exchange Offer as it has in such
                                 interpretive letters to third parties. Based on
                                 these interpretations by the staff of the
                                 Division of Corporation Finance of the

                                 Commission, and subject to the two immediately
                                 following sentences, the Corporation and the
                                 Trust believe that New Capital Securities
                                 issued pursuant to this Exchange Offer in
                                 exchange for Old Capital Securities may be
                                 offered for resale, resold and otherwise
                                 transferred by a holder thereof (other than a
                                 holder who is a broker-dealer) without further
                                 compliance with the registration and prospectus
                                 delivery requirements of the Securities Act,
                                 provided that such New Capital Securities are
                                 acquired in the ordinary course of such
                                 holder's business and that such holder is not
                                 participating, and has no arrangement or
                                 understanding with any person to participate,
                                 in a distribution (within the meaning of the
                                 Securities Act) of such New Capital Securities.
                                 However, any holder of Old Capital Securities
                                 who is an "affiliate" of the Corporation or the
                                 Trust or who intends to participate in the
                                 Exchange Offer for the purpose of distributing
                                 the New Capital Securities, or any
                                 broker-dealer who purchased the Old Capital
                                 Securities from the Trust to resell pursuant to
                                 Rule 144A or any other available exemption
                                 under the Securities Act, (a) will not be able
                                 to rely on the interpretations of the staff of
                                 the Division of Corporation Finance of the
                                 Commission set forth in the above-mentioned
                                 interpretive letters, (b) will not be permitted
                                 or entitled to tender such Old Capital
                                 Securities in the Exchange Offer and (c) must
                                 comply with the registration and prospectus
                                 delivery requirements of the Securities Act in
                                 connection with any sale or other transfer of
                                 such Old Capital Securities unless such sale is
                                 made pursuant to an exemption from such
                                 requirements. In addition, as described below,
                                 if any broker-dealer holds Old Capital
                                 Securities acquired for its own account as a
                                 result of market-making or other trading
                                 activities and exchanges such Old Capital
                                 Securities for New Capital Securities, then
                                 such broker-dealer must deliver a prospectus
                                 meeting the requirements of the Securities Act
                                 in connection with any resales of such New
                                 Capital Securities.
 
                                 Each holder of Old Capital Securities who
                                 wishes to exchange Old Capital Securities for
                                 New Capital Securities in the Exchange Offer
                                 will be required to represent that (i) it is
                                 not an "affiliate" of the Corporation or the
                                 Trust, (ii) any New Capital Securities to be
                                 received by it are being acquired in the
                                 ordinary course of its business, (iii) it has
                                 no arrangement or understanding with any person
                                 to participate in a distribution (within the
                                 meaning of the Securities Act) of such New
                                 Capital Securities, and (iv) if such holder is
                                 not a broker-dealer, such holder is not engaged
                                 in, and does not intend to engage in, a
                                 distribution (within the meaning of the
                                 Securities Act) of such New Capital Securities.
                                 Each broker-dealer that receives New Capital
                                 Securities for its own account pursuant to the
                                 Exchange Offer must acknowledge that it
                                 acquired the Old Capital Securities for its own
                                 account as the result of market-making
                                 activities or other trading activities and must
                                 agree that it will deliver a prospectus meeting
                                 the requirements of the Securities Act in
                                 connection with any resale of such New Capital
                                 Securities. The Letter of Transmittal states
                                 that, by so acknowledging and by delivering a
                                 prospectus, a broker-dealer will not be

                                 within the meaning of the Securities Act. Based
                                 on the position taken by the staff of the
                                 Division of Corporation Finance of the
                                 Commission in the interpretive letters referred
                                 to above, the Corporation and the Trust believe
                                 that Participating Broker-Dealers who acquired
                                 Old Capital Securities for their own accounts
                                 as a result of market-making activities or
                                 other trading activities may fulfill their
                                 prospectus delivery requirements with respect
                                 to the New Capital Securities received upon

                                 of the Trust's New Capital Securities which
                                 have been registered under the Securities Act

                                 Security). The New Capital Securities will be
                                 issued and the Old Capital Securities were
                                 issued under the Declaration. The New Capital

                                 remain outstanding after consummation of the
                                 Exchange Offer will vote together as a single
                                 class for purposes of determining whether
                                 holders of the requisite percentage in
                                 outstanding Liquidation Amount thereof have
                                 taken certain actions or exercised certain
                                 rights under the Declaration. See "Description

Rating........................   The New Capital Securities are expected to be
                                 rated "BB+" by Duff & Phelps Credit Rating Co.
 
Absence of Market for the
New Capital Securities........   The New Capital Securities will be a new issue
                                 of securities for which there currently is no
                                 market. Although Robert W. Baird & Co.
                                 Incorporated, the initial purchaser of the Old
                                 Capital Securities (the "Initial Purchaser"),
                                 has informed the Trust and the Corporation that
                                 it currently intends to make a market in the
                                 New Capital Securities, the Initial Purchaser
                                 is not obligated to do so, and any such market
                                 making may be discontinued at any time without
                                 notice. Accordingly, there can be no assurance
                                 as to the development or liquidity of any
                                 market for the New Capital Securities. The
                                 Trust and the Corporation do not intend to
                                 apply for listing of the New Capital Securities
                                 on any securities exchange or for quotation
                                 through the Nasdaq National Market. See "Plan

                                  RISK FACTORS
 
     Prospective investors should carefully review the information contained
elsewhere in this Prospectus and should particularly consider the following
factors in connection with the Exchange Offer and the New Capital Securities
offered hereby.
 
RANKING OF SUBORDINATE OBLIGATIONS UNDER THE GUARANTEE AND JUNIOR SUBORDINATED
DEBENTURES
 
     The obligations of the Corporation under the Guarantee and under the Junior
Subordinated Debentures will be unsecured and rank subordinate and junior in
right of payment to all present and future Senior Indebtedness of the
Corporation. No payment may be made of the principal of, or premium, if any, or
interest on the Junior Subordinated Debentures or in respect of any redemption,
retirement, purchase or other acquisition of any of the Junior Subordinated
Debentures, at any time when (i) there shall have occurred and be continuing a
default in any payment in respect of any Senior Indebtedness, or there has been
an acceleration of the maturity thereof because of a default or (ii) in the
event of the acceleration of the maturity of the Junior Subordinated Debentures
until payment has been made on all amounts of Senior Indebtedness. At December
31, 1996, the aggregate principal amount of outstanding Senior Indebtedness of
the Corporation was approximately $30.3 million. 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 (and thus the ability of holders of the Capital Securities to
benefit indirectly from such distribution) is subject to the prior claims of
creditors of that subsidiary (including depositors), except to the extent that
the Corporation may itself be recognized as a creditor of that subsidiary. At
December 31, 1996, the subsidiaries of the Corporation had total liabilities
(excluding liabilities owed to the Corporation) of approximately $2.56 billion.
Accordingly, the Junior Subordinated Debentures will be effectively subordinated
to all existing and future liabilities of the Corporation's subsidiaries
(including the Corporation's subsidiaries' deposit liabilities) and all
liabilities of any future subsidiaries of the Corporation. None of the
Indenture, the Guarantee, the Common Guarantee or the Declaration places any
limitation on the amount of secured or unsecured debt, including Senior
Indebtedness, that may be incurred by the Corporation or any of its
subsidiaries. See "Description of New Securities -- Description of New Guarantee
- -- Status" and "-- Description of New Junior Subordinated Debentures --
Subordination."
 
HOLDING COMPANY STRUCTURE; RESTRICTIONS ON DIVIDENDS BY SUBSIDIARIES
 
     The ability of the Trust to pay amounts due on the Capital Securities is
dependent upon the Corporation making payments on the Junior Subordinated
Debentures as and when required. The Corporation is a holding company and
substantially all of the operating assets of the Corporation and its
consolidated subsidiaries are owned by such subsidiaries. The Corporation relies
primarily on interest and dividends from such subsidiaries to meet its
obligations for payment of principal and interest on its outstanding debt
obligations and corporate expenses. Accordingly, the Junior Subordinated
Debentures will be subordinated effectively 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. In addition, the bank
subsidiaries of the Corporation (the "Banks") are subject to certain
restrictions imposed by federal law on any extensions of credit to, and certain
other transactions with, the Corporation and certain other affiliates, and on
investments in stock or other securities thereof. Such restrictions prevent the
Corporation and such other affiliates from borrowing from the Banks unless the
loans are secured by various types of collateral. Further, such secured loans,
other transactions and investments by any of the Banks are generally limited in
amount as to the Corporation and as to each of such other affiliates to 10% of
such Bank's capital and surplus and as to the Corporation and all of such other
affiliates to an aggregate of 20% of such Bank's capital and surplus.
 
     With respect to the Banks, there are regulatory limitations on the payment
of dividends directly or indirectly to the Corporation. At December 31, 1996,
under regulations of the Office of the Comptroller of the Currency (the "OCC")
and applicable state banking authorities, the total capital available for
payment of dividends by the Banks to the Corporation was approximately $33.7
million. However, the OCC has the power to prohibit any act, including the
payment of dividends, if such act would reduce bank capital to a point that,
 
                                       16
<PAGE>   18
 
in its opinion, would render the bank undercapitalized and thus constitute an
unsafe or unsound banking practice.
 
OPTION TO EXTEND INTEREST PAYMENT PERIOD; TAX CONSIDERATIONS
 
     So long as no Debenture Event of Default (as defined herein) shall have
occurred and be continuing, the Corporation will have the right under the
Indenture to defer payments of interest on the Junior Subordinated Debentures at
any time or from time to time for a period not exceeding 10 consecutive
semiannual periods with respect to each Extension Period, provided that no
Extension Period shall end on a date other than an Interest Payment Date or
extend beyond the Stated Maturity Date. Upon any such deferral, semiannual
Distributions on the Trust Securities by the Trust will be deferred (and the
amount of Distributions to which holders of the Trust Securities are entitled
will accumulate additional Distributions thereon at the rate of 9.35% per annum,
compounded semiannually, but not exceeding the interest rate then accruing on
the Junior Subordinated Debentures) from the relevant payment date for such
Distributions during any such Extension Period.
 
     Prior to the termination of any such Extension Period, the Corporation may
further extend such Extension Period, provided that such extension does not
cause such Extension Period to exceed 10 consecutive semiannual periods, end on
a date other than an Interest Payment Date or extend beyond the Stated Maturity
Date. Upon the termination of any Extension Period and the payment of all
interest then accrued and unpaid on the Junior Subordinated Debentures (together
with interest thereon at the annual rate of 9.35%, compounded semiannually, 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 "Description of New Securities -- Description of New Capital
Securities -- Distributions" and "-- Description of New Junior Subordinated
Debentures -- Option to Extend Interest Payment Date."
 
     The Corporation has no current plan to exercise its right to defer payments
of interest on the Junior Subordinated Debentures. However, should the
Corporation exercise its right to defer payments of interest on the Junior
Subordinated Debentures, each holder of Capital Securities will be required to
accrue income (as original issue discount ("OID")) in respect of the deferred
stated interest allocable to its Capital Securities for United States federal
income tax purposes, which will be allocated but not distributed to holders of
Capital Securities. As a result, during an Extension Period, each holder of
Capital Securities will recognize income for United States federal income tax
purposes in advance of the receipt of cash and will not receive the cash related
to such income from the Trust if the holder disposes of the Capital Securities
prior to the record date for the payment of Distributions thereafter. See
"Certain Federal Income Tax Considerations -- Interest Income and Original Issue
Discount" and "-- Sales or Redemption of Capital Securities."
 
     Should the Corporation elect to exercise its right to defer payments of
interest on the Junior Subordinated Debentures, the market price of the Capital
Securities is likely to be affected. A holder that disposes of its Capital
Securities during an Extension Period, therefore, might not receive the same
return on its investment as a holder that continues to hold its Capital
Securities. In addition, the mere existence of the Corporation's right to defer
payments of interest on the Junior Subordinated Debentures may cause the market
price of the Capital Securities to be more volatile than the market prices of
other securities on which OID accrues and that are not subject to such
deferrals.
 
SPECIAL EVENT REDEMPTION
 
     Upon the occurrence and continuation of a Special Event (including a Tax
Event or a Regulatory Capital Event, in each case, as defined under "Description
of New Securities -- Description of New Junior Subordinated Debentures --
Special Event Prepayment") prior to March 1, 2007, the Corporation will have the
right to prepay the Junior Subordinated Debentures in whole (but not in part) at
the Special Event Prepayment Price within 90 days following the occurrence of
such Special Event and therefore cause a mandatory redemption of the Trust
Securities at the Special Event Redemption Price. Any such redemption is subject
to the Corporation having received prior approval of the Federal Reserve, if
then required under
 
                                       17
<PAGE>   19
 
applicable guidelines or policies of the Federal Reserve. See "Description of
New Securities -- Description of New Capital Securities -- Redemption."
 
PROPOSED TAX LEGISLATION
 
     On February 6, 1997, as part of President Clinton's Fiscal 1998 Budget
Proposal, the United States Treasury Department proposed legislation that would,
among other things, deny an issuer a deduction for United States federal income
tax purposes for the payment of interest on instruments with characteristics
similar to the Junior Subordinated Debentures. If the proposed legislation were
enacted in its current form, it is not expected to apply to the Junior
Subordinated Debentures by reason of the currently proposed prospective
effective date. There can be no assurances, however, that the proposed
legislation, if enacted, or similar legislation enacted after the date hereof
would not adversely affect the tax treatment of the Junior Subordinated
Debentures, resulting in a Tax Event, which may permit the Corporation, upon
approval of the Federal Reserve (if then required under applicable capital
guidelines or policies of the Federal Reserve) to cause a redemption of the
Trust Securities at the Special Event Redemption Price by electing to prepay the
Junior Subordinated Debentures at the Special Event Prepayment Price. See
"Description of New Securities -- Description of New Capital Securities --
Redemption" and "-- Description of New Junior Subordinated Debentures -- Special
Event Prepayment." See also "Certain Federal Income Tax Consequences -- Proposed
Tax Legislation."
 
EXCHANGE OF CAPITAL SECURITIES FOR JUNIOR SUBORDINATED DEBENTURES
 
     The Corporation will have the right at any time to terminate the Trust and
cause the Junior Subordinated Debentures to be distributed to the holders of the
Trust Securities in liquidation of the Trust. Such right is subject to (i) the
Corporation having received an opinion of counsel to the effect that such
distribution will not be a taxable event to holders of Capital Securities and
(ii) prior approval of the Federal Reserve, if then required. Under current
United States federal income tax law, a distribution of Junior Subordinated
Debentures upon the dissolution of the Trust would not be a taxable event to
holders of the Capital Securities. See "Certain Federal Income Tax
Considerations -- Distribution of Junior Subordinated Debentures to Holders of
Capital Securities."
 
POSSIBLE ADVERSE EFFECT ON MARKET PRICES
 
     There can be no assurance as to the market prices for Capital Securities or
Junior Subordinated Debentures distributed to the holders of Capital Securities
if a termination of the Trust were to occur. Accordingly, the Capital Securities
or the Junior Subordinated Debentures may trade at a discount from the price
that the investor paid to purchase the Capital Securities offered hereby.
Because holders of Capital Securities may receive Junior Subordinated Debentures
in liquidation of the Trust and because Distributions are otherwise limited to
payments on the Junior Subordinated Debentures, prospective purchasers of New
Capital Securities are also making an investment decision with regard to the New
Junior Subordinated Debentures and should carefully review all the information
regarding the New Junior Subordinated Debentures contained herein. See
"Description of New Securities -- Description of New Junior Subordinated
Debentures."
 
RIGHTS UNDER THE GUARANTEE
 
     The First National Bank of Chicago will act as Guarantee Trustee and will
hold the Guarantee for the benefit of the holders of the Capital Securities. The
First National Bank of Chicago will also act as Property Trustee and as
Debenture Trustee under the Indenture. First Chicago Delaware Inc. will act as
Delaware Trustee under the Declaration. The Guarantee will guarantee to the
holders of the Capital Securities the following payments, to the extent not paid
by the Trust: (i) any accumulated and unpaid Distributions required to be paid
on the Capital Securities, to the extent that the Trust has funds on hand
legally available therefor, (ii) the applicable Redemption Price with respect to
any Capital Securities called for redemption, to the extent that the Trust has
funds on hand legally available therefor, and (iii) upon a voluntary or
involuntary termination, winding up or liquidation of the Trust (unless the
Junior Subordinated Debentures are distributed
 
                                       18
<PAGE>   20
 
to holders of the Capital 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 Trust has funds on hand legally available
therefor at such time and (b) the amount of assets of the Trust remaining
available for distribution to holders of the Capital Securities at such time.
The holders of a majority in Liquidation Amount of the Capital Securities will
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 Guarantee or
to direct the exercise of any trust power conferred upon the Guarantee Trustee.
Any holder of the Capital Securities may institute a legal proceeding directly
against the Corporation to enforce its rights under the Guarantee without first
instituting a legal proceeding against the Trust, the Guarantee Trustee or any
other person or entity. If the Corporation defaults on its obligation to pay
amounts payable under the Junior Subordinated Debentures, the Trust will not
have sufficient funds for the payment of Distributions or amounts payable on
redemption of the Capital Securities or otherwise, and, in such event, holders
of the Capital Securities will not be able to rely upon the Guarantee for
payment of such amounts. Instead, in the event a Debenture Event of Default
shall have occurred and be continuing and such event is attributable to the
failure of the Corporation to pay principal of or premium, if any, or interest
on the Junior Subordinated Debentures on the payment date on which such payment
is due and payable, then a holder of Capital Securities may institute a legal
proceeding directly against the Corporation for enforcement of payment to such
holder of the principal of or premium, if any, or interest on such Junior
Subordinated Debentures having a principal amount equal to the Liquidation
Amount of the Capital Securities of such holder (a "Direct Action").
Notwithstanding any payments made to a holder of Capital Securities by the
Corporation in connection with a Direct Action, the Corporation shall remain
obligated to pay the principal of and premium, if any, and interest on the
Junior Subordinated Debentures, and the Corporation shall be subrogated to the
rights of the holder of such Capital Securities with respect to payments on the
Capital Securities to the extent of any payments made by the Corporation to such
holder in any Direct Action. Except as described herein, holders of Capital
Securities will not be able to exercise directly any other remedy available to
the holders of the Junior Subordinated Debentures or to assert directly any
other rights in respect of the Junior Subordinated Debentures. See "Description
of New Securities -- Description of New Junior Subordinated Debentures --
Enforcement of Certain Rights by Holders of Capital Securities," "Description of
New Junior Subordinated Debentures -- Debenture Events of Default" and "--
Description of New Guarantee." The Declaration will provide that each holder of
Capital Securities by acceptance thereof agrees to the provisions of the
Indenture.
 
LIMITED VOTING RIGHTS
 
     Holders of Capital Securities generally will have limited voting rights
relating only to the modification of the terms of the Capital Securities, the
termination or liquidation of the Trust and the exercise of the Trust's rights
as holder of the Junior Subordinated Debentures. Holders of Capital Securities
will not be entitled to vote to appoint, remove or replace, or to increase or
decrease the number of, the Issuer Trustees, which voting rights are vested
exclusively in the holder of the Common Securities, except upon the occurrence
of certain events described herein. The Property Trustee, the Administrative
Trustees and the Corporation may amend the Trust Agreement without the consent
of holders of Capital Securities to ensure that the Trust will be classified for
United States federal income tax purposes as a grantor trust even if such action
adversely affects the interests of such holders. Holders of Capital Securities
will have no voting rights with respect to any matters submitted to a vote of
the Corporation's stockholders. See "Description of New Securities --
Description of New Capital Securities -- Voting Rights; Amendment of the
Declaration" and "-- Removal of Issuer Trustees."
 
CONSEQUENCES OF A FAILURE TO EXCHANGE OLD CAPITAL SECURITIES
 
     The Old Capital Securities have not been registered under the Securities
Act or any state securities laws and therefore may not be offered, sold or
otherwise transferred except in compliance with the registration requirements of
the Securities Act and any other applicable securities laws, or pursuant to an
exemption therefrom or in a transaction not subject thereto, and in each case in
compliance with certain other conditions and restrictions. Old Capital
Securities which remain outstanding after consummation of the Exchange Offer
will continue to bear a legend reflecting such restrictions on transfer. In
addition, upon consummation of the
 
                                       19
<PAGE>   21
 
Exchange Offer, holders of Old Capital Securities which remain outstanding will
not be entitled to any rights to have such Old Capital Securities registered
under the Securities Act or to any similar rights under the Registration Rights
Agreement (subject to certain limited exceptions). The Corporation and the Trust
do not intend to register under the Securities Act any Old Capital Securities
which remain outstanding after consummation of the Exchange Offer (subject to
such limited exceptions, if applicable). To the extent that Old Capital
Securities are tendered and accepted in the Exchange Offer, a holder's ability
to sell untendered Old Capital Securities could be adversely affected.
 
     The New Capital Securities and any Old Capital Securities which remain
outstanding after consummation of the Exchange Offer will vote together as a
single class for purposes of determining whether holders of the requisite
percentage in outstanding Liquidation Amount thereof have taken certain actions
or exercised certain rights under the Declaration. See "Description of New
Securities -- Description of New Capital Securities -- Voting Rights; Amendment
of the Declaration."
 
     The Old Capital Securities provide, among other things, that, if a
registration statement relating to the Exchange Offer has not been filed by
August 22, 1997 and declared effective by September 21, 1997, the Distribution
rate borne by the Old Capital Securities commencing on September 22, 1997 will
increase by 0.25% per annum until the Exchange Offer is consummated. Upon
consummation of the Exchange Offer, holders of Old Capital Securities will not
be entitled to any increase in the Distribution rate thereon or any further
registration rights under the Registration Rights Agreement, except under
limited circumstances. See "Description of Old Capital Securities."
 
ABSENCE OF PUBLIC MARKET
 
     The Old Capital Securities were issued to, and the Corporation believes
such securities are currently owned by, a relatively small number of beneficial
owners. The Old Capital Securities have not been registered under the Securities
Act and will be subject to restrictions on transferability if they are not
exchanged for the New Capital Securities. Although the New Capital Securities
may be resold or otherwise transferred by the holders (who are not affiliates of
the Corporation or the Trust) without compliance with the registration
requirements under the Securities Act, they will constitute a new issue of
securities with no established trading market. Old Capital Securities may be
transferred by the holders thereof only in blocks having a Liquidation Amount of
not less than $100,000 (100 Old Capital Securities). New Capital Securities may
be transferred by the holders thereof in blocks having a Liquidation Amount of
$1,000 (one New Capital Security) or integral multiples thereof. The Corporation
and the Trust have been advised by the Initial Purchaser that the Initial
Purchaser presently intends to make a market in the New Capital Securities.
However, the Initial Purchaser is not obligated to do so and any market-making
activity with respect to the New Capital Securities may be discontinued at any
time without notice. In addition, such market-making activity will be subject to
the limits imposed by the Securities Act and the Exchange Act and may be limited
during the Exchange Offer. Accordingly, no assurance can be given that an active
public or other market will develop for the New Capital Securities or the Old
Capital Securities or as to the liquidity of or the trading market for the New
Capital Securities or the Old Capital Securities. If an active public market
does not develop, the market price and liquidity of the New Capital Securities
may be adversely affected.
 
     If a public trading market develops for the New Capital Securities, future
trading prices will depend on many factors, including, among other things,
prevailing interest rates, the Corporation's results and the market for similar
securities. Depending on prevailing interest rates, the market for similar
securities and other factors, including the financial condition of the
Corporation, the New Capital Securities may trade at a discount.
 
     Notwithstanding the registration of the New Capital Securities in the
Exchange Offer, holders who are "affiliates" (as defined under Rule 405 of the
Securities Act) of the Corporation or the Trust may publicly offer for sale or
resell the New Capital Securities only in compliance with the provisions of Rule
144 under the Securities Act.

     Each broker-dealer that receives New Capital Securities for its own account
in exchange for Old Capital Securities, where such Old Capital Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such New Capital Securities. See "Plan of
Distribution."
 
EXCHANGE OFFER PROCEDURES
 
     Issuance of the New Capital Securities in exchange for Old Capital
Securities pursuant to the Exchange Offer will be made only after a timely
receipt by the Trust of such Old Capital Securities, a properly completed and
duly executed Letter of Transmittal and all other required documents. Therefore,
holders of the Old Capital Securities desiring to tender such Old Capital
Securities in exchange for New Capital Securities should allow sufficient time
to ensure timely delivery. Neither the Corporation nor the Trust is under any
duty to give notification of defects or irregularities with respect to the
tenders of Old Capital Securities for exchange.

                                USE OF PROCEEDS
 
     Neither the Corporation nor the Trust will receive any cash proceeds from
the issuance of the New Capital Securities offered hereby. In consideration for
issuing the New Capital Securities in exchange for Old Capital Securities as
described in this Prospectus, the Trust will receive Old Capital Securities in
like Liquidation Amount. The Old Capital Securities surrendered in exchange for
the New Capital Securities will be retired and cancelled.
 
     The proceeds to the Trust (without giving effect to expenses of the
offering payable by the Corporation) from the offering of the Old Capital
Securities was $40,000,000. All of the proceeds from the sale of the Old Capital
Securities were invested by the Trust in the Old Junior Subordinated Debentures.
The net proceeds from the sale of the Old Junior Subordinated Debentures are
being used as follows: (i) $13.6 million to repay in full the Term Loan (as
defined below); (ii) $.6 million to repay in full the long-term borrowings of
First National (with an interest rate of 8.250% per annum at December 31, 1996
and a maturity date of June 1, 1997); (iii) $6.58 million to repay in full the
long-term borrowings of Country Bank (with a weighted average interest rate of
7.895% per annum at December 31, 1996 and maturity dates ranging from demand to
April 2, 1999); (iv) $1.3 million to purchase certain minority interests in
subsidiaries of Country Bank; and (v) the balance to fund working capital and
other general corporate purposes. At December 31, 1996, the interest rate on the
Corporation's term loan (the "Term Loan") was 7.125% per annum. The Term Loan
requires semi-annual principal payments through the November 10, 2000 maturity
date.
 
     Pending such application by the Corporation, such net proceeds may be
temporarily invested in short-term interest-bearing securities. The New Capital
Securities are expected to be eligible to qualify as Tier 1 capital under the
capital guidelines of the Federal Reserve.
 
                  RATIOS OF EARNINGS TO COMBINED FIXED CHARGES
 
     The following table sets forth the ratios of earnings to combined fixed
charges of the Corporation on a consolidated basis for the respective periods
indicated.

</TABLE>
 
     The ratio of earnings to fixed charges has been computed by dividing
earnings before income taxes and fixed charges by fixed charges. Fixed charges,
excluding interest on deposits, consists of interest on indebtedness and
one-third of rental expense (which is deemed representative of the interest
factor). Fixed charges, including interest on deposits, consist of both the
foregoing items plus interest on deposits.

                                   THE TRUST
 
     The Trust is a statutory business trust formed under Delaware law pursuant
to (i) a declaration of trust, dated as of March 11, 1997, executed by the
Corporation, as Sponsor, The First National Bank of Chicago, as Property
Trustee, First Chicago Delaware Inc., as Delaware Trustee and the Administrative
Trustee named therein (the "Initial Declaration"), and (ii) the filing of a
certificate of trust with the Secretary of State of the State of Delaware on
March 11, 1997. The Trust exists for the exclusive purposes of (i) issuing and
selling the Trust Securities, which represent undivided beneficial interests in
the assets of the Trust, (ii) investing the gross proceeds from the sale of the
Trust Securities in the Junior Subordinated Debentures and (iii) engaging in
only those other activities necessary, advisable or incidental thereto.
Accordingly, the Junior Subordinated Debentures will be the sole assets of the
Trust and payments under the Junior Subordinated Debentures will be the sole
revenues of the Trust. All of the Common Securities are owned directly by the
Corporation. The Common Securities will rank pari passu, and payments will be
made thereon pro rata, with the Capital Securities, except that upon the
occurrence and during the continuance of an event of default under the
Declaration ("Event of Default") resulting from a Debenture Event of Default,
the rights of the Corporation as holder of the Common Securities to payments in
respect of Distributions and payments upon liquidation, redemption or otherwise
will be subordinated to the rights of the holders of the Capital Securities. See
"Description of New Securities -- Description of New Capital Securities --
Subordination of Common Securities." The Corporation has acquired Common
Securities in a Liquidation Amount equal to at least 3% of the total capital of
the Trust. The Trust has a term of 31 years, but may terminate earlier as
provided in the Declaration. The Trust's business and affairs are conducted by
trustees (the "Issuer Trustees") appointed by the Corporation as holder of the
Common Securities. The Issuer Trustees are The First National Bank of Chicago as
the Property Trustee (the "Property Trustee"), First Chicago Delaware Inc., as
the Delaware Trustee (the "Delaware Trustee"), and three individual trustees
(the "Administrative Trustees"), who are officers or employees of, or affiliated
with, the Corporation. The First National Bank of Chicago, as Property Trustee,
acts as sole indenture trustee under the Declaration. The First National Bank of
Chicago also acts as indenture trustee under the Guarantee and the Indenture.
See "Description of New Securities -- Description of New Guarantee" and "--
Description of New Junior Subordinated Debentures." The holder of the Common
Securities or, if an Event of Default under the Declaration has occurred and is
continuing, the holders of a majority in Liquidation Amount of the Capital
Securities, will be entitled to appoint, remove or replace the Property Trustee
and/or the Delaware Trustee. In no event will the holders of the Capital
Securities have the right to vote to appoint, remove or replace the
Administrative Trustees; such voting rights will be vested exclusively in the
holder of the Common Securities. The duties and obligations of each Issuer
Trustee are governed by the Declaration. The Corporation, as issuer of the
Junior Subordinated Debentures, will pay directly all fees, expenses, debts and
obligations (other than the Trust Securities) related to the Trust and the
offering and exchange of the Capital Securities, including all ongoing costs,
expenses and liabilities of the Trust. The principal executive office of the
Trust is c/o AMCORE Financial, Inc., 501 Seventh Street, Rockford, Illinois
61104. Attention: John R. Hecht.
 
                               THE EXCHANGE OFFER
 
PURPOSE OF THE EXCHANGE OFFER
 
     In connection with the sale of the Old Capital Securities, the Corporation
and the Trust entered into the Registration Rights Agreement with the Initial
Purchaser, pursuant to which the Corporation and the Trust agreed to file and to
use their reasonable efforts to cause to become effective with the Commission a
registration statement with respect to the exchange of the Old Capital
Securities for capital securities with terms identical in all material respects
to the terms of the Old Capital Securities. A copy of the Registration Rights
Agreement has been filed as an exhibit to the Registration Statement of which
this Prospectus is a part.
 
     The Exchange Offer is being made to satisfy the contractual obligations of
the Corporation and the Trust under the Registration Rights Agreement. The form
and terms of the New Capital Securities are the same as the form and terms of
the Old Capital Securities except that the New Capital Securities have been
registered
 
                                       30
<PAGE>   32
 
under the Securities Act and will not be subject to the $100,000 minimum
Liquidation Amount transfer restriction and certain other restrictions on
transfer applicable to the Old Capital Securities and will not provide for any
increase in the Distribution rate thereon. In that regard, the Old Capital
Securities provide, among other things, that, if a registration statement
relating to the Exchange Offer has not been filed by August 22, 1997 and
declared effective by September 21, 1997, the Distribution rate borne by the Old
Capital Securities commencing on September 22, 1997 will increase by 0.25% per
annum until the Exchange Offer is consummated. Upon consummation of the Exchange
Offer, holders of Old Capital Securities will not be entitled to any increase in
the Distribution rate thereon or any further registration rights under the
Registration Rights Agreement, except under limited circumstances. See "Risk
Factors -- Consequences of a Failure to Exchange Old Capital Securities" and
"Description of Old Capital Securities."
 
     The Exchange Offer is not being made to, nor will the Trust accept tenders
for exchange from, holders of Old Capital Securities in any jurisdiction in
which the Exchange Offer or the acceptance thereof would not be in compliance
with the securities or blue sky laws of such jurisdiction.
 
     Unless the context requires otherwise, the term "holder" with respect to
the Exchange Offer means any person in whose name the Old Capital Securities are
registered on the books of the Trust or any other person who has obtained a
properly completed bond power from the registered holder, or any person whose
Old Capital Securities are held of record by The Depository Trust Company
("DTC") who desires to deliver such Old Capital Securities by book-entry
transfer at DTC.
 
     Pursuant to the Exchange Offer, the Corporation will exchange as soon as
practicable after the date hereof, the Old Guarantee for the New Guarantee and
the Old Junior Subordinated Debentures, in an amount corresponding to the Old
Capital Securities accepted for exchange, for a like aggregate principal amount
of the New Junior Subordinated Debentures. The New Guarantee and New Junior
Subordinated Debentures have been registered under the Securities Act.
 
TERMS OF THE EXCHANGE OFFER
 
     The Trust hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and in the accompanying Letter of Transmittal, to
exchange up to $40,000,000 aggregate Liquidation Amount of New Capital
Securities for a like aggregate Liquidation Amount of Old Capital Securities
properly tendered on or prior to the Expiration Date and not properly withdrawn
in accordance with the procedures described below. The Trust will issue,
promptly after the Expiration Date, an aggregate Liquidation Amount of up to
$40,000,000 of New Capital Securities in exchange for a like principal amount of
outstanding Old Capital Securities tendered and accepted in connection with the
Exchange Offer. Holders may tender their Old Capital Securities in whole or in
part in a Liquidation Amount of not less than $100,000 (100 Capital Securities)
or any integral multiple of $1,000 Liquidation Amount (one Capital Security) in
excess thereof.
 
     The Exchange Offer is not conditioned upon any minimum Liquidation Amount
of Old Capital Securities being tendered. As of the date of this Prospectus,
$40,000,000 aggregate Liquidation Amount of the Old Capital Securities is
outstanding.
 
     Holders of Old Capital Securities do not have any appraisal or dissenters'
rights in connection with the Exchange Offer. Old Capital Securities which are
not tendered for or are tendered but not accepted in connection with the
Exchange Offer will remain outstanding and be entitled to the benefits of the
Declaration, but will not be entitled to any further registration rights under
the Registration Rights Agreement, except under limited circumstances. See "Risk
Factors -- Consequences of a Failure to Exchange Old Capital Securities" and
"Description of Old Securities."
 
     If any tendered Old Capital Securities are not accepted for exchange
because of an invalid tender, the occurrence of certain other events set forth
herein or otherwise, certificates for any such unaccepted Old Capital Securities
will be returned, without expense, to the tendering holder thereof promptly
after the Expiration Date.
 
     Holders who tender Old Capital Securities in connection with the Exchange
Offer will not be required to pay brokerage commissions or fees or, subject to
the instructions in the Letter of Transmittal, transfer taxes
 
                                       31
<PAGE>   33
 
with respect to the exchange of Old Capital Securities in connection with the
Exchange Offer. The Corporation will pay all charges and expenses, other than
certain applicable taxes described below, in connection with the Exchange Offer.
See "-- Fees and Expenses."
 
     NEITHER THE CORPORATION, THE BOARD OF DIRECTORS OF THE CORPORATION NOR ANY
ISSUER TRUSTEE OF THE TRUST MAKES ANY RECOMMENDATION TO HOLDERS OF OLD CAPITAL
SECURITIES AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR ANY PORTION
OF THEIR OLD CAPITAL SECURITIES PURSUANT TO THE EXCHANGE OFFER. IN ADDITION, NO
ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. HOLDERS OF OLD CAPITAL
SECURITIES MUST MAKE THEIR OWN DECISION WHETHER TO TENDER PURSUANT TO THE
EXCHANGE OFFER AND, IF SO, THE AGGREGATE AMOUNT OF OLD CAPITAL SECURITIES TO
TENDER BASED ON SUCH HOLDERS OWN FINANCIAL POSITION AND REQUIREMENTS.
 
     The term "Expiration Date" means 5:00 p.m., New York City time, on
                         , 1997 unless the Exchange Offer is extended by the
Corporation or the Trust (in which case the term "Expiration Date" shall mean
the latest date and time to which the Exchange Offer is extended).
 
     The Corporation and the Trust expressly reserve the right in their sole and
absolute discretion, subject to applicable law, at any time and from time to
time, (i) to delay the acceptance of the Old Capital Securities for exchange,
(ii) to terminate the Exchange Offer (whether or not any Old Capital Securities
have theretofore been accepted for exchange) if the Trust determines, in its
sole and absolute discretion, that any of the events or conditions referred to
under "-- Conditions to the Exchange Offer" have occurred or exist or have not
been satisfied, (iii) to extend the Expiration Date of the Exchange Offer and
retain all Old Capital Securities tendered pursuant to the Exchange Offer,
subject, however, to the right of holders of Old Capital Securities to withdraw
their tendered Old Capital Securities as described under "-- Withdrawal Rights,"
and (iv) to waive any condition or otherwise amend the terms of the Exchange
Offer in any respect. If the Exchange Offer is amended in a manner determined by
the Corporation and the Trust to constitute a material change, or if the
Corporation and the Trust waive a material condition of the Exchange Offer, the
Corporation and the Trust will promptly disclose such amendment by means of a
prospectus supplement that will be distributed to the holders of the Old Capital
Securities, and the Corporation and the Trust will extend the Exchange Offer to
the extent required by Rule 14e-1 under the Exchange Act.
 
     Any such delay in acceptance, extension, termination or amendment will be
followed promptly by oral or written notice thereof to the Exchange Agent and by
making a public announcement thereof, and such announcement in the case of an
extension will be made no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date. Without limiting
the manner in which the Corporation and the Trust may choose to make any public
announcement and subject to applicable law, the Corporation and the Trust shall
have no obligation to publish, advertise or otherwise communicate any such
public announcement other than by issuing a release to an appropriate news
agency.

agent for tendering holders for the purpose of receiving Old Capital Securities,
Letters of Transmittal and related documents and transmitting New Capital
Securities to validly tendering holders. Such exchange will be made promptly
after the Expiration Date. If for any reason whatsoever, acceptance for exchange
or the exchange of any Old Capital Securities tendered pursuant to the Exchange
Offer is delayed (whether before or after the Trust's acceptance for exchange of
Old Capital Securities) or the Trust extends the Exchange Offer or is unable to
accept for exchange or exchange Old Capital Securities tendered pursuant to the
Exchange Offer, then, without prejudice to the Trust's rights set forth herein,
the Exchange Agent may, nevertheless, on behalf of the Trust and subject to Rule
14e-1(c) under the Exchange Act, retain tendered Old Capital Securities and such
Old Capital Securities may not be withdrawn except to the extent tendering
holders are entitled to withdrawal rights as described under "-- Withdrawal
Rights."
 
     Pursuant to the Letter of Transmittal, a holder of Old Capital Securities
will warrant and agree in the Letter of Transmittal that it has full power and
authority to tender, exchange, sell, assign and transfer Old Capital Securities,
that the Trust will acquire good, marketable and unencumbered title to the
tendered Old Capital Securities, free and clear of all liens, restrictions,
charges and encumbrances, and the Old Capital Securities tendered for exchange
are not subject to any adverse claims or proxies. The holder also will warrant
and agree that it will, upon request, execute and deliver any additional
documents deemed by the Trust or the Exchange Agent to be necessary or desirable
to complete the exchange, sale, assignment, and transfer of the Old Capital
Securities tendered pursuant to the Exchange Offer.
 
PROCEDURES FOR TENDERING OLD CAPITAL SECURITIES
 
     VALID TENDER. Except as set forth below, in order for Old Capital
Securities to be validly tendered pursuant to the Exchange Offer, a properly
completed and duly executed Letter of Transmittal (or facsimile thereof), with
any required signature guarantees and any other required documents, must be
received by the Exchange Agent at one of its addresses set forth under "--
Exchange Agent," and either (i) tendered Old Capital Securities must be received
by the Exchange Agent, or (ii) such Old Capital Securities must be tendered
pursuant to the procedures for book-entry transfer set forth below and a
book-entry confirmation must be received by the Exchange Agent, in each case on
or prior to the Expiration Date, or (iii) the guaranteed delivery procedures set
forth below must be complied with.
 
     If less than all of the Old Capital Securities are tendered, a tendering
holder should fill in the amount of Old Capital Securities being tendered in the
appropriate box on the Letter of Transmittal. The entire amount of Old Capital
Securities delivered to the Exchange Agent will be deemed to have been tendered
unless otherwise indicated.
 
     THE METHOD OF DELIVERY OF CERTIFICATES, THE LETTER OF TRANSMITTAL AND ALL
OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER,
AND DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL, RETURN RECEIPT REQUESTED,
PROPERLY INSURED, OR AN OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
     BOOK-ENTRY TRANSFER. The Exchange Agent will establish an account with
respect to the Old Capital Securities at DTC for purposes of the Exchange Offer
within two business days after the date of this Prospectus. Any financial
institution that is a participant in DTC's book-entry transfer facility system
may make a book-entry delivery of the Old Capital Securities by causing DTC to
transfer such Old Capital Securities into the Exchange Agent's account at DTC in
accordance with DTC's procedures for transfers. However, although delivery of
Old Capital Securities may be effected through book-entry transfer into the
 
                                       33
<PAGE>   35
 
Exchange Agent's account at DTC, the Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, with any required signature
guarantees and any other required documents, must in any case be delivered to
and received by the Exchange Agent at its address set forth under "-- Exchange
Agent" on or prior to the Expiration Date, or the guaranteed delivery procedure
set forth below must be complied with.
 
     DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH DTC'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.
 
     SIGNATURE GUARANTEES. Certificates for the Old Capital Securities need not
be endorsed and signature guarantees on the Letter of Transmittal are
unnecessary unless (a) a certificate for the Old Capital Securities is
registered in a name other than that of the person surrendering the certificate
or (b) such holder completes the box entitled "Special Issuance Instructions" or
"Special Delivery Instructions" in the Letter of Transmittal. In the case of (a)
or (b) above, such certificates for Old Capital Securities must be duly endorsed
or accompanied by a properly executed bond power, with the endorsement or
signature on the bond power and on the Letter of Transmittal guaranteed by a
firm or other entity identified in Rule 17Ad-15 under the Exchange Act as an
"eligible guarantor institution," including (as such terms are defined therein):
(i) a bank; (ii) a broker, dealer, municipal securities broker or dealer or
government securities broker or dealer; (iii) a credit union; (iv) a national
securities exchange, registered securities association or clearing agency; or
(v) a savings association that is a participant in a Securities Transfer
Association (an "Eligible Institution"), unless surrendered on behalf of such
Eligible Institution. See Instruction 1 to the Letter of Transmittal.
 
     GUARANTEED DELIVERY. If a holder desires to tender Old Capital Securities
pursuant to the Exchange Offer and the certificates for such Old Capital
Securities are not immediately available or time will not permit all required
documents to reach the Exchange Agent on or prior to the Expiration Date, or the
procedure for book-entry transfer cannot be completed on a timely basis, such
Old Capital Securities may nevertheless be tendered, provided that all of the
following guaranteed delivery procedures are complied with:
 
     (a) such tenders are made by or through an Eligible Institution;
 
     (b) a properly completed and duly executed Notice of Guaranteed Delivery,
substantially in the form accompanying the Letter of Transmittal, is received by
the Exchange Agent, as provided below, on or prior to the Expiration Date; and
 
     (c) the certificates (or a book-entry confirmation) representing all
tendered Old Capital Securities, in proper form for transfer, together with a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof), with any required signature guarantees and any other documents
required by the Letter of Transmittal, are received by the Exchange Agent within
three New York Stock Exchange trading days after the date of execution of such
Notice of Guaranteed Delivery.
 
     The Notice of Guaranteed Delivery may be delivered by hand, or transmitted
by facsimile or mail to the Exchange Agent and must include a guarantee by an
Eligible Institution in the form set forth in such notice.
 
     Notwithstanding any other provision hereof, the delivery of New Capital
Securities in exchange for Old Capital Securities tendered and accepted for
exchange pursuant to the Exchange Offer will in all cases be made only after
timely receipt by the Exchange Agent of Old Capital Securities, or of a
book-entry confirmation with respect to such Old Capital Securities, and a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof), together with any required signature guarantees and any other
documents required by the Letter of Transmittal. Accordingly, the delivery of
New Capital Securities might not be made to all tendering holders at the same
time, and will depend upon when Old Capital Securities, book-entry confirmations
with respect to Old Capital Securities and other required documents are received
by the Exchange Agent.
 
     The Trust's acceptance for exchange of Old Capital Securities tendered
pursuant to any of the procedures described above will constitute a binding
agreement between the tendering holder and the Trust upon the terms and subject
to the conditions of the Exchange Offer.
 
     DETERMINATION OF VALIDITY. All questions as to the form of documents,
validity, eligibility (including time of receipt) and acceptance for exchange of
any tendered Old Capital Securities will be determined by the
 
                                       34
<PAGE>   36
 
Corporation and the Trust, in their sole discretion, whose determination shall
be final and binding on all parties. The Corporation and the Trust reserve the
absolute right, in their sole and absolute discretion, to reject any and all
tenders determined by them not to be in proper form or the acceptance of which,
or exchange for, may, in the opinion of counsel to the Corporation and the
Trust, be unlawful. The Corporation and the Trust also reserve the absolute
right, subject to applicable law, to waive any of the conditions of the Exchange
Offer as set forth under "-- Conditions to the Exchange Offer" or any condition
or irregularity in any tender of Old Capital Securities of any particular holder
whether or not similar conditions or irregularities are waived in the case of
other holders.
 
     The interpretation by the Corporation and the Trust of the terms and
conditions of the Exchange Offer (including the Letter of Transmittal and the
instructions thereto) will be final and binding. No tender of Old Capital
Securities will be deemed to have been validly made until all irregularities
with respect to such tender have been cured or waived. Neither the Corporation,
the Trust, any affiliates or assigns of the Corporation or the Trust, the
Exchange Agent nor any other person shall be under any duty to give any
notification of any irregularities in tenders or incur any liability for failure
to give any such notification.
 
     If any Letter of Transmittal, endorsement, bond power, power of attorney,
or any other document required by the Letter of Transmittal is signed by a
trustee, executor, administrator, guardian, attorney-in-fact, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person should so indicate when signing, and unless waived by the
Corporation and the Trust, proper evidence satisfactory to the Corporation and
the Trust, in their sole discretion, of such person's authority to so act must
be submitted.
 
     A beneficial owner of Old Capital Securities that are held by or registered
in the name of a broker, dealer, commercial bank, trust company or other nominee
or custodian is urged to contact such entity promptly if such beneficial holder
wishes to participate in the Exchange Offer.
 
RESALES OF NEW CAPITAL SECURITIES
 
     The Trust is making the Exchange Offer for the New Capital Securities in
reliance on the position of the staff of the Division of Corporation Finance of
the Commission as set forth in certain interpretive letters addressed to third
parties in other transactions. However, neither the Corporation nor the Trust
sought its own interpretive letter and there can be no assurance that the staff
of the Division of Corporation Finance of the Commission would make a similar
determination with respect to the Exchange Offer as it has in such interpretive
letters to third parties. Based on these interpretations by the staff of the
Division of Corporation Finance of the Commission, and subject to the two
immediately following sentences, the Corporation and the Trust believe that New
Capital Securities issued pursuant to this Exchange Offer in exchange for Old
Capital Securities may be offered for resale, resold and otherwise transferred
by a holder thereof (other than a holder who is a broker-dealer) without further
compliance with the registration and prospectus delivery requirements of the
Securities Act, provided that such New Capital Securities are acquired in the
ordinary course of such holder's business and that such holder is not
participating, and has no arrangement or understanding with any person to
participate, in a distribution (within the meaning of the Securities Act) of
such New Capital Securities. However, any holder of Old Capital Securities who
is an "affiliate" of the Corporation or the Trust or who intends to participate
in the Exchange Offer for the purpose of distributing New Capital Securities, or
any broker-dealer who purchased Old Capital Securities from the Trust to resell
pursuant to Rule 144A or any other available exemption under the Securities Act,
(a) will not be able to rely on the interpretations of the staff of the Division
of Corporation Finance of the Commission set forth in the above-mentioned
interpretive letters, (b) will not be permitted or entitled to tender such Old
Capital Securities in the Exchange Offer and (c) must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any sale or other transfer of such Old Capital Securities unless
such sale is made pursuant to an exemption from such requirements. In addition,
as described below, if any broker-dealer holds Old Capital Securities acquired
for its own account as a result of market-making or other trading activities and
exchanges such Old Capital Securities for New Capital Securities, then such
broker-dealer must deliver a prospectus meeting the requirements of the
Securities Act in connection with any resales of such New Capital Securities.
 
                                       35
<PAGE>   37
 
     Each holder of Old Capital Securities who wishes to exchange Old Capital
Securities for New Capital Securities in the Exchange Offer will be required to
represent that (i) it is not an "affiliate" of the Corporation or the Trust,
(ii) any New Capital Securities to be received by it are being acquired in the
ordinary course of its business, (iii) it has no arrangement or understanding
with any person to participate in a distribution (within the meaning of the
Securities Act) of such New Capital Securities, and (iv) if such holder is not a
broker-dealer, such holder is not engaged in, and does not intend to engage in,
a distribution (within the meaning of the Securities Act) of such New Capital
Securities. In addition, the Corporation and the Trust may require such holder,
as a condition to such holder's eligibility to participate in the Exchange
Offer, to furnish to the Corporation and the Trust (or an agent thereof) in
writing information as to the number of "beneficial owners" (within the meaning
of Rule 13d-3 under the Exchange Act) on behalf of whom such holder holds the
Capital Securities to be exchanged in the Exchange Offer. Each broker-dealer
that receives New Capital Securities for its own account pursuant to the
Exchange Offer must acknowledge that it acquired the Old Capital Securities for
its own account as the result of market-making activities or other trading
activities and must agree that it will deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of such New
Capital Securities. The Letter of Transmittal states that by so acknowledging
and by delivering a prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act. Based on the
position taken by the staff of the Division of Corporation Finance of the
Commission in the interpretive letters referred to above, the Corporation and
the Trust believe that Participating Broker-Dealers who acquired Old Capital
Securities for their own accounts as a result of market-making activities or
other trading activities may fulfill their prospectus delivery requirements with
respect to the New Capital Securities received upon exchange of such Old Capital
Securities (other than Old Capital Securities which represent an unsold
allotment from the original sale of the Old Capital Securities) with a
prospectus meeting the requirements of the Securities Act, which may be the
prospectus prepared for an exchange offer so long as it contains a description
of the plan of distribution with respect to the resale of such New Capital
Securities. Accordingly, this Prospectus, as it may be amended or supplemented
from time to time, may be used by a Participating Broker-Dealer during the
period referred to below in connection with resales of New Capital Securities
received in exchange for Old Capital Securities where such Old Capital
Securities were acquired by such Participating Broker-Dealer for its own account
as a result of market-making or other trading activities. Subject to certain
provisions set forth in the Registration Rights Agreement, the Corporation and
the Trust have agreed that this Prospectus, as it may be amended or supplemented
from time to time, may be used by a Participating Broker-Dealer in connection
with resales of such New Capital Securities for a period ending 90-days after
the Expiration Date (subject to extension under certain limited circumstances
described below) or, if earlier, when all such New Capital Securities have been
disposed of by such Participating Broker-Dealer. See "Plan of Distribution."
However, a Participating Broker-Dealer who intends to use this Prospectus in
connection with the resale of New Capital Securities received in exchange for
Old Capital Securities pursuant to the Exchange Offer must notify the
Corporation or the Trust, or cause the Corporation or the Trust to be notified,
on or prior to the Expiration Date, that it is a Participating Broker-Dealer.
Such notice may be given in the space provided for that purpose in the Letter of
Transmittal or may be delivered to the Exchange Agent at one of the addresses
set forth herein under "-- Exchange Agent." Any Participating Broker-Dealer who
is an "affiliate" of the Corporation or the Trust may not rely on such
interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction.
 
     In that regard, each Participating Broker-Dealer who surrenders Old Capital
Securities pursuant to the Exchange Offer will be deemed to have agreed, by
execution of the Letter of Transmittal, that, upon receipt of notice from the
Corporation or the Trust of the occurrence of any event or the discovery of any
fact which makes any statement contained or incorporated by reference in this
Prospectus untrue in any material respect or which causes this Prospectus to
omit to state a material fact necessary in order to make the statements
contained or incorporated by reference herein, in light of the circumstances
under which they were made, not misleading or of the occurrence of certain other
events specified in the Registration Rights Agreement, such Participating
Broker-Dealer will suspend the sale of New Capital Securities (or the New
Guarantee or the New Junior Subordinated Debentures, as applicable) pursuant to
this Prospectus until the Corporation or the Trust has amended or supplemented
this Prospectus to correct such misstatement or omission and has
 
                                       36
<PAGE>   38
 
furnished copies of the amended or supplemented Prospectus to such Participating
Broker-Dealer or the Corporation or the Trust has given notice that the sale of
the New Capital Securities (or the New Guarantee or the New Junior Subordinated
Debentures, as applicable) may be resumed, as the case may be. If the
Corporation or the Trust gives such notice to suspend the sale of the New
Capital Securities (or the New Guarantee or the New Junior Subordinated
Debentures, as applicable), it shall extend the 90-day period referred to above
during which Participating Broker-Dealers are entitled to use this Prospectus in
connection with the resale of New Capital Securities by the number of days
during the period from and including the date of the giving of such notice to
and including the date when Participating Broker-Dealers shall have received
copies of the amended or supplemented Prospectus necessary to permit resales of
the New Capital Securities or to and including the date on which the Corporation
or the Trust has given notice that the sale of New Capital Securities (or the
New Guarantee or the New Junior Subordinated Debentures, as applicable) may be
resumed, as the case may be.
 
WITHDRAWAL RIGHTS
 
     Except as otherwise provided herein, tenders of Old Capital Securities may
be withdrawn at any time on or prior to the Expiration Date.
 
     In order for a withdrawal to be effective a written, telegraphic, telex or
facsimile transmission of such notice of withdrawal must be timely received by
the Exchange Agent at one of its addresses set forth under "-- Exchange Agent"
on or prior to the Expiration Date. Any such notice of withdrawal must specify
the name of the person who tendered the Old Capital Securities to be withdrawn,
the aggregate principal amount of Old Capital Securities to be withdrawn, and
(if certificates for such Old Capital Securities have been tendered) the name of
the registered holder of the Old Capital Securities as set forth on the Old
Capital Securities, if different from that of the person who tendered such Old
Capital Securities. If Old Capital Securities have been delivered or otherwise
identified to the Exchange Agent, then prior to the physical release of such Old
Capital Securities, the tendering holder must submit the serial numbers shown on
the particular Old Capital Securities to be withdrawn and the signature on the
notice of withdrawal must be guaranteed by an Eligible Institution, except in
the case of Old Capital Securities tendered for the account of an Eligible
Institution. If Old Capital Securities have been tendered pursuant to the
procedures for book-entry transfer set forth in "-- Procedures for Tendering Old
Capital Securities," the notice of withdrawal must specify the name and number
of the account at DTC to be credited with the withdrawal of Old Capital
Securities, in which case a notice of withdrawal will be effective if delivered
to the Exchange Agent by written, telegraphic, telex or facsimile transmission.
Withdrawals of tenders of Old Capital Securities may not be rescinded. Old
Capital Securities properly withdrawn will not be deemed validly tendered for
purposes of the Exchange Offer, but may be retendered at any subsequent time on
or prior to the Expiration Date by following any of the procedures described
above under "-- Procedures for Tendering Old Capital Securities."
 
     All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Trust, in its sole
discretion, whose determination shall be final and binding on all parties.
Neither the Corporation, the Trust, any affiliates or assigns of the Corporation
or the Trust, the Exchange Agent nor any other person shall be under any duty to
give any notification of any irregularities in any notice of withdrawal or incur
any liability for failure to give any such notification. Any Old Capital
Securities which have been tendered but which are withdrawn will be returned to
the holder thereof promptly after withdrawal.
 
DISTRIBUTIONS ON NEW CAPITAL SECURITIES
 
     Holders of Old Capital Securities whose Old Capital Securities are accepted
for exchange will not receive Distributions on such Old Capital Securities and
will be deemed to have waived the right to receive any Distributions on such Old
Capital Securities accumulated from and after March 25, 1997. Accordingly,
holders of New Capital Securities as of the record date for the payment of
Distributions on June 15, 1997 will be entitled to receive Distributions
accumulated from and after March 25, 1997.
 
                                       37
<PAGE>   39
 
CONDITIONS TO THE EXCHANGE OFFER
 
     Notwithstanding any other provisions of the Exchange Offer, or any
extension of the Exchange Offer, the Corporation and the Trust will not be
required to accept for exchange, or to exchange, any Old Capital Securities for
any New Capital Securities, and, as described below, may terminate the Exchange
Offer (whether or not any Old Capital Securities have theretofore been accepted
for exchange) or may waive any conditions to or amend the Exchange Offer, if any
of the following conditions have occurred or exists or have not been satisfied:
 
     (a) there shall occur a change in the current interpretation by the staff
of the Commission which permits the New Capital Securities issued pursuant to
the Exchange Offer in exchange for Old Capital Securities to be offered for
resale, resold and otherwise transferred by holders thereof (other than
broker-dealers and any such holder which is an "affiliate" of the Corporation or
the Trust within the meaning of Rule 405 under the Securities Act) without
compliance with the registration and prospectus delivery provisions of the
Securities Act provided that such New Capital Securities are acquired in the
ordinary course of such holders' business and such holders have no arrangement
or understanding with any person to participate in the distribution of such New
Capital Securities; or
 
     (b) any law, statute, rule or regulation shall have been adopted or enacted
which, in the judgment of the Corporation or the Trust, would reasonably be
expected to impair its ability to proceed with the Exchange Offer; or
 
     (c) a stop order shall have been issued by the Commission or any state
securities authority suspending the effectiveness of the Registration Statement
or proceedings shall have been initiated or, to the knowledge of the Corporation
or the Trust, threatened for that purpose any governmental approval has not been
obtained, which approval the Corporation or the Trust shall, in its sole
discretion, deem necessary for the consummation of the Exchange Offer as
contemplated hereby.
 
     If the Corporation or the Trust determines in its sole and absolute
discretion that any of the foregoing events or conditions has occurred or exists
or has not been satisfied, it may, subject to applicable law, terminate the
Exchange Offer (whether or not any Old Capital Securities have theretofore been
accepted for exchange) or may waive any such condition or otherwise amend the
terms of the Exchange Offer in any respect. If such waiver or amendment
constitutes a material change to the Exchange Offer, the Corporation or the
Trust will promptly disclose such waiver or amendment by means of a prospectus
supplement that will be distributed to the registered holders of the Old Capital
Securities and will extend the Exchange Offer to the extent required by Rule
14e-1 under the Exchange Act.

FEES AND EXPENSES
 
     The Corporation has agreed to pay the Exchange Agent reasonable and
customary fees for its services and will reimburse it for its reasonable
out-of-pocket expenses in connection therewith. The Corporation will also pay
brokerage houses and other custodians, nominees and fiduciaries the reasonable
out-of-pocket expenses incurred by them in forwarding copies of this Prospectus
and related documents to the beneficial owners of Old Capital Securities, and in
handling or tendering for their customers.
 
     Holders who tender their Old Capital Securities for exchange will not be
obligated to pay any transfer taxes in connection therewith. If, however, New
Capital Securities are to be delivered to, or are to be issued in the name of,
any person other than the registered holder of the Old Capital Securities
tendered, or if a transfer tax is imposed for any reason other than the exchange
of Old Capital Securities in connection with the Exchange Offer, then the amount
of any such transfer taxes (whether imposed on the registered holder or any
other persons) will be payable by the tendering holder. If satisfactory evidence
of payment of such taxes or exemption therefrom is not submitted with the Letter
of Transmittal, the amount of such transfer taxes will be billed directly to
such tendering holder.
 
     Neither the Corporation nor the Trust will make any payment to brokers,
dealers or other nominees soliciting acceptances of the Exchange Offer.

                         DESCRIPTION OF NEW SECURITIES
 
DESCRIPTION OF NEW CAPITAL SECURITIES
 
     Pursuant to the terms of the Declaration, the Trust has issued the Old
Capital Securities and the Common Securities and will issue the New Capital
Securities. The New Capital Securities will represent preferred beneficial
interests in the Trust and the holders of the New Capital Securities and the Old
Capital Securities will be entitled to a preference over the Common Securities
in certain circumstances with respect to Distributions and amounts payable on
redemption of the Trust Securities or liquidation of the Trust. See "--
Subordination of Common Securities" below. The Declaration has been qualified
under the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").
The following description does not purport to be complete and is subject to, and
is qualified in its entirety by reference to, all of the provisions of the
Declaration and those terms made a part of the Declaration by the Trust
Indenture Act. Certain capitalized terms used herein are defined in the
Declaration.
 
     General. The Capital Securities (including the Old Capital Securities and
the New Capital Securities) are limited to $40,000,000 aggregate Liquidation
Amount at any one time outstanding. The New Capital Securities will rank pari
passu, and payments will be made thereon pro rata, with the Old Capital
Securities and the Common Securities except as described under "-- Subordination
of Common Securities." Legal title to the New Junior Subordinated Debentures
will be held by the Property Trustee in trust for the benefit of the holders of
the New Capital Securities and the Common Securities. The New Guarantee will not
guarantee payment of Distributions or amounts payable on redemption of the New
Capital Securities or on liquidation of the Trust when the Trust does not have
funds on hand legally available for such payments. See "--Description of New
Guarantee."
 
     Distributions. Distributions on the New Capital Securities will be
cumulative, will accumulate from March 25, 1997 and will be payable
semi-annually in arrears on June 15 and December 15 of each year, commencing
June 15, 1997, at the annual rate of 9.35% of the Liquidation Amount to the
holders of the New Capital Securities on the relevant record dates. The record
dates will be the 15th day of the month immediately preceding the month in which
the relevant Distribution Date (as defined herein) falls. The amount of
Distributions payable for any period will be computed on the basis of a 360-day
year of twelve 30-day months and, for any period of less than a full calendar
month, the number of days elapsed in such month. In the event that any date on
which Distributions are payable on the New Capital Securities is not a Business
Day (as defined herein), 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
next succeeding Business Day falls 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 (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 New
York, New York, or Chicago, Illinois are authorized or required by law or
executive order to close.
 
     So long as no Debenture Event of Default shall have occurred and be
continuing, the Corporation will have the right under the Indenture to elect to
defer the payment of interest on the New Junior Subordinated Debentures at any
time and 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
shall end on a date other than an Interest Payment Date or extend beyond the
Stated Maturity Date. Upon any such election, semiannual Distributions on the
New Capital Securities will be deferred by the Trust during such Extension
Period. Distributions to which holders of the New Capital Securities are
entitled during any such Extension Period will accumulate additional
Distributions thereon at the rate per annum of 9.35% thereof, compounded
semiannually from the relevant Distribution Date, but not exceeding the interest
rate then accruing on the New Junior Subordinated Debentures. The term
"Distributions," as used herein, shall include any such additional
Distributions.
 
     Prior to the termination of any such Extension Period, the Corporation may
further extend such Extension Period, provided that such extension does not
cause such Extension Period to exceed 10 consecutive
 
                                       40
<PAGE>   42
 
semiannual periods, end on a date other than an Interest Payment Date or extend
beyond the Stated Maturity Date. Upon the termination of any such Extension
Period and the payment of all amounts then due, and subject to the foregoing
limitations, the Corporation may elect to begin a new Extension Period. 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 of any Extension
Period or any extension thereof at least five Business Days prior to the earlier
of (i) the date the Distributions on the New Capital Securities would have been
payable except for the election to begin or extend such Extension Period and
(ii) the date the Administrative Trustees are required to give notice to any
securities exchange or to holders of the Capital Securities of the record date
or the date such Distributions are payable, but in any event not less than five
Business Days prior to such record date. There is no limitation on the number of
times that the Corporation may elect to begin an Extension Period. See "--
Description of New Junior Subordinated Debentures -- Option to Extend Interest
Payment Date" and "Certain Federal Income Tax Considerations -- Interest Income
and Original Issue Discount."
 
     During any such Extension Period, the Corporation may not (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
(other than (a) dividends or distributions in shares of, or options, warrants or
rights to subscribe for or purchase shares of, common stock of the Corporation,
(b) any declaration of a dividend in connection with the implementation of a
stockholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (c)
as a result of reclassification of the Corporation's capital stock or the
exchange or conversion of one class or series of the Corporation's capital stock
for another class or series of the Corporation's capital stock, (d) the purchase
of fractional interests in shares of the Corporation's capital stock pursuant to
the conversion or exchange provisions of such capital stock or the security
being converted or exchanged, (e) purchases of common stock related to the
issuance of common stock or rights under any of the Corporation's benefit plans
for its directors, officers or employees or any of the Corporation's dividend
reinvestment plans and (f) purchases of Common Stock in connection with the
satisfaction by the Guarantor of its obligations pursuant to any contract or
security requiring the Guarantor to purchase shares of Common Stock), (ii) make
any payment of principal or premium, if any, or interest on or repay, repurchase
or redeem any debt securities of the Corporation (including Other Debentures)
that rank pari passu with or junior in right of payment to the New Junior
Subordinated Debentures or (iii) make any guarantee payments (other than
payments under the Guarantee) with respect to any guarantee by the Corporation
of the debt securities of any subsidiary of the Corporation (including Other
Guarantees) if such guarantee ranks pari passu with or junior in right of
payment to the New Junior Subordinated Debentures.
 
     Although the Corporation may in the future exercise its option to defer
payments of interest on the New Junior Subordinated Debentures, the Corporation
has no such current intention.
 
     The revenue of the Trust available for distribution to holders of the
Capital Securities will be limited to payments under the New Junior Subordinated
Debentures. See "-- Description of New Junior Subordinated Debentures --
General." If the Corporation does not make interest payments on the New Junior
Subordinated Debentures, the Property Trustee will not have funds available to
pay Distributions on the New Capital Securities. The payment of Distributions on
the New Capital Securities (if and to the extent the Trust has funds on hand
legally available for the payment of such Distributions) will be guaranteed by
the Corporation on a limited basis as set forth herein under "-- Description of
New Guarantee."
 
     Redemption. Upon the repayment on the Stated Maturity Date or prepayment
prior to the Stated Maturity Date of the Junior Subordinated Debentures, the
proceeds from such repayment or prepayment 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 of a date of redemption (the
"Redemption Date"), at the applicable Redemption Price, which shall be equal to
(i) in the case of the repayment of the Junior Subordinated Debentures on the
Stated Maturity Date, the Maturity Redemption Price (equal to the principal of,
and accrued and unpaid interest on, the Junior Subordinated Debentures), (ii) in
the case of the optional prepayment of the Junior Subordinated Debentures before
the Initial Optional Prepayment Date upon the occurrence and continuation of a
Special Event, the Special Event Redemption Price (equal to the
 
                                       41
<PAGE>   43
 
Special Event Prepayment Price in respect of the Junior Subordinated Debentures)
and (iii) in the case of the optional prepayment of the Junior Subordinated
Debentures on or after the Initial Optional Prepayment Date, the Optional
Redemption Price (equal to the Optional Prepayment Price in respect of the
Junior Subordinated Debentures). See "-- Description of New Junior Subordinated
Debentures -- Optional Prepayment" and "-- Special Event Prepayment."
 
     "Like Amount" means (i) with respect to a redemption of the Trust
Securities, Trust Securities having a Liquidation Amount equal to the principal
amount of Junior Subordinated Debentures to be paid in accordance with their
terms and (ii) with respect to a distribution of Junior Subordinated Debentures
upon the liquidation of the Trust, Junior Subordinated Debentures having a
principal amount equal to the Liquidation Amount of the Trust Securities of the
holder to whom such Junior Subordinated Debentures are distributed.
 
     The Corporation will have the option to prepay the Junior Subordinated
Debentures, (i) in whole or in part, on or after the Initial Optional Prepayment
Date, at the applicable Optional Prepayment Price and (ii) in whole but not in
part, at any time before the Initial Optional Prepayment Date, upon the
occurrence of a Special Event, at the Special Event Prepayment Price, in each
case subject to receipt of prior approval by the Federal Reserve, if then
required under applicable capital guidelines or policies of the Federal Reserve.
See "-- Description of New Junior Subordinated Debentures -- Optional
Prepayment" and "-- Special Event Prepayment."
 
     Liquidation of the Trust and Distribution of Junior Subordinated
Debentures. The Corporation will have the right at any time to terminate the
Trust and cause the Junior Subordinated Debentures to be distributed to the
holders of the Trust Securities in liquidation of the Trust. Such right is
subject to (i) the Corporation having received an opinion of counsel to the
effect that such distribution will not be a taxable event to holders of Capital
Securities and (ii) the prior approval of the Federal Reserve, if then required
under applicable capital guidelines or policies of the Federal Reserve.
 
     The Trust shall automatically terminate upon the first to occur of: (i)
certain events of bankruptcy, dissolution or liquidation of the Corporation;
(ii) the distribution of a Like Amount of the Junior Subordinated Debentures to
the holders of the Trust Securities, if the Corporation, as Sponsor, has given
written direction to the Property Trustee to terminate the Trust (which
direction is optional and, except as described above, wholly within the
discretion of the Corporation, as Sponsor); (iii) redemption of all of the Trust
Securities as described under "-- Redemption"; (iv) expiration of the term of
the Trust; and (v) the entry of an order for the dissolution of the Trust by a
court of competent jurisdiction.
 
     If a termination occurs as described in clause (i), (ii), (iv), or (v) of
the preceding paragraph, the Trust shall be liquidated by the Administrative
Trustees as expeditiously as the Administrative Trustees determine to be
possible by distributing, after satisfaction of liabilities to creditors of the
Trust as provided by applicable law, to the holders of the Trust Securities a
Like Amount of the Junior Subordinated Debentures, unless such distribution is
determined by the Property Trustee not to be practicable, in which event such
holders will be entitled to receive out of the assets of the Trust legally
available for distribution to holders, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, an amount equal to the
aggregate of the Liquidation Amount plus accumulated and unpaid Distributions
thereon to the date of payment (such amount being the "Liquidation
Distribution"). If the Liquidation Distribution can be paid only in part because
the Trust has insufficient assets on hand legally available to pay in full the
aggregate Liquidation Distribution, then the amounts payable directly by the
Trust on the Capital Securities and the Common Securities shall be paid on a pro
rata basis, except that if a Debenture Event of Default has occurred and is
continuing, the Capital Securities shall have a priority over the Common
Securities. See "-- Subordination of Common Securities" below.
 
     After the liquidation date is fixed for any distribution of Junior
Subordinated Debentures to holders of the Trust Securities, (i) the Trust
Securities will no longer be deemed to be outstanding, (ii) The Depository Trust
Company ("DTC") or its nominee will receive, in respect of each registered
global certificate, if any, representing Trust Securities and held by it, a
registered global certificate or certificates representing the Junior
Subordinated Debentures to be delivered upon such distribution and (iii) any
certificates representing
 
                                       42
<PAGE>   44
 
Trust Securities not held by DTC or its nominee will be deemed to represent
Junior Subordinated Debentures having a principal amount equal to the
Liquidation Amount of such Trust Securities, and bearing accrued and unpaid
interest in an amount equal to the accumulated and unpaid Distributions on such
Trust Securities until such certificates are presented to the Administrative
Trustees or their agent for cancellation, whereupon the Corporation will issue
to such holder, and the Debenture Trustee will authenticate, a certificate
representing such Junior Subordinated Debentures.
 
     There can be no assurance as to the market prices for the New Capital
Securities or the New Junior Subordinated Debentures that may be distributed in
exchange for the Trust Securities if a dissolution and liquidation of the Trust
were to occur. Accordingly, the New Capital Securities, or the Junior
Subordinated Debentures that an investor may receive on dissolution and
liquidation of the Trust, may trade at a discount to the price that the investor
paid to purchase the New Capital Securities.
 
REDEMPTION PROCEDURES
 
     If applicable, Trust Securities shall be redeemed at the applicable
Redemption Price with the proceeds from the contemporaneous repayment or
prepayment of the Junior Subordinated Debentures. Any redemption of Trust
Securities shall be made and the applicable Redemption Price shall be payable on
the Redemption Date only to the extent that the Trust has funds legally
available for the payment of such applicable Redemption Price. See also
"-- Subordination of Common Securities."
 
     If the Trust gives a notice of redemption in respect of the Capital
Securities, then, by 12:00 noon, New York City time, on the Redemption Date, to
the extent funds are legally available, with respect to the Capital Securities
held by DTC or its nominees, the Property Trustee will pay or cause the Paying
Agent to pay the Redemption Price to DTC. See "-- Form, Denomination, Book-Entry
Procedures and Transfer" below. With respect to the Capital Securities held in
certificated form, the Property Trustee, to the extent funds are legally
available, will give irrevocable instructions and authority to the Paying Agent
and will irrevocably deposit with the Paying Agent for the Capital Securities
funds sufficient to pay the applicable Redemption Price to the holders thereof
upon surrender of their certificates evidencing the Capital Securities. See
"-- Payment and Paying Agency." Distributions payable on or prior to the
Redemption Date shall be payable to the holders of such Capital Securities on
the relevant record dates for the related Distribution Dates. If notice of
redemption shall have been given and funds deposited with the Property Trustee
to pay the Redemption Price for the Capital Securities called for redemption,
then upon the date of such deposit all rights of the holders of such Capital
Securities will cease, except the right of the holders of such Capital
Securities to receive the applicable Redemption Price, but without interest on
such Redemption Price, and such Capital Securities will cease to be outstanding.
In the event that any Redemption Date is not a Business Day, then the applicable
Redemption Price payable on such date will be paid 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 next succeeding Business Day falls in the
next calendar year, such payment shall be made on the immediately preceding
Business Day. In the event that payment of the applicable Redemption Price is
improperly withheld or refused and not paid either by the Trust or by the
Corporation pursuant to the Guarantee as described under "-- Description of New
Guarantee," (i) distributions on Capital Securities called for redemption will
accumulate at the then applicable rate, from the Redemption Date originally
established by the Trust to the date such applicable Redemption Price is
actually paid, and (ii) the actual payment date will be the Redemption Date for
purposes of calculating the applicable Redemption Price.
 
     Subject to applicable law (including, without limitation, United States
federal securities law and the regulations of the Federal Reserve), the
Corporation or its subsidiaries may at any time and from time to time purchase
outstanding Capital Securities by tender, in the open market or by private
agreement.
 
     Notice of any redemption will be mailed at least 30 days but not more than
60 days prior to the Redemption Date to each holder of Trust Securities at its
registered address. Unless the Corporation defaults in payment of the applicable
Redemption Price on, or in the repayment of, the Junior Subordinated Debentures,
on and after the Redemption Date, Distributions will cease to accrue on the
Trust Securities called for redemption.
 
                                       43
<PAGE>   45
 
     Subordination of Common Securities. Payment of Distributions on, and the
Redemption Price of, the Trust Securities, as applicable, shall be made pro rata
based on the Liquidation Amount of the Trust 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
applicable Redemption Price of, any of the Common Securities, and no other
payment on account of the redemption, liquidation or other acquisition of the
Common Securities, shall be made unless payment in full in cash of all
accumulated and unpaid Distributions on all of the outstanding Capital
Securities for all Distribution periods terminating on or prior thereto or, in
the case of Capital Securities called for redemption on a Redemption Date on or
prior thereto, the full amount of the Redemption Price therefor, 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 Capital Securities then due and payable.
 
     In the case of any Event of Default, the Corporation as holder of the
Common Securities will be deemed to have waived any right to act with respect to
such Event of Default until the effect of such Event of Default shall have been
cured, waived or otherwise eliminated. Until any such Event of Default has been
so cured, waived or otherwise eliminated, the Property Trustee shall act solely
on behalf of the holders of the Capital Securities and not on behalf of the
Corporation as holder of the Common Securities, and only the holders of the
Capital Securities will have the right to direct the Property Trustee to act on
their behalf.
 
     Events of Default; Notice. The occurrence of a Debenture Event of Default
(see "-- Description of New Junior Subordinated Debentures -- Debenture Events
of Default") constitutes an "Event of Default" under the Declaration.
 
     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 the Capital Securities, the
Administrative Trustees and the Corporation, as Sponsor, unless such Event of
Default shall have been cured or waived. The Corporation, as Sponsor, and the
Administrative Trustees are required to file annually with the Property Trustee
a certificate as to whether or not they are in compliance with all the
conditions and covenants applicable to them under the Declaration.
 
     If a Debenture Event of Default has occurred and is continuing, the Capital
Securities shall have a preference over the Common Securities as described under
"-- Liquidation of the Trust and Distribution of Junior Subordinated Debentures"
and "-- Subordination of Common Securities."
 
     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 Capital Securities. In no event will the holders of the Capital
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 Declaration.
 
     Merger or Consolidation of Issuer Trustees. Any corporation 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 corporation resulting from any merger, conversion or
consolidation to which such Issuer Trustee shall be a party, or any corporation
succeeding to all or substantially all the corporate trust business of such
Issuer Trustee, shall be the successor of such Issuer Trustee under the
Declaration, provided such corporation shall be otherwise qualified and
eligible.
 
     Mergers, Conversions, Consolidations, Amalgamations or Replacements of the
Trust. The Trust may not merge or convert with or into, consolidate, amalgamate,
or be replaced by, or convey, transfer or lease its properties and assets as an
entirety or substantially as an entirety to any corporation or other Person,
except as described below. The Trust may, at the request of the Corporation, as
Sponsor, with the consent of the Administrative Trustees but without the consent
of the holders of the Capital Securities, merge with or into,
 
                                       44
<PAGE>   46
 
consolidate, amalgamate, or be replaced by or convey, transfer or lease its
properties and assets as an entirety or substantially as an entirety to a trust
organized as such under the laws of any State; provided, that (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Trust Securities or (b) substitutes for the Trust Securities
other securities having substantially the same terms as the Trust Securities
(the "Successor Securities") so long as the Successor Securities rank the same
as the Trust Securities rank in priority with respect to distributions and
payments upon liquidation, redemption and otherwise, (ii) the Corporation
expressly appoints a trustee of such successor entity possessing the same powers
and duties as the Property Trustee with respect to the 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 Capital Securities are
then listed or quoted, if any, (iv) if the Capital Securities (including any
Successor Securities) are rated by any nationally recognized statistical rating
organization prior to such transaction, such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not cause the
Capital Securities (including any Successor Securities) or, if the Junior
Subordinated Debentures are so rated, the Junior Subordinated Debentures, to be
downgraded by any such nationally recognized statistical rating organization,
(v) such merger, conversion, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights, preferences
and privileges of the holders of the Trust Securities (including any Successor
Securities) in any material respect (other than any dilution of such holders'
interests in the new entity), (vi) such successor entity has a purpose identical
to that of the Trust, (vii) prior to such merger, conversion, consolidation,
amalgamation, replacement, conveyance, transfer or lease, the Corporation has
received an opinion from independent counsel to the Trust experienced in such
matters to the effect that (a) such merger, conversion, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not adversely
affect the rights, preferences and privileges of the holders of the Trust
Securities (including any Successor Securities) in any material respect (other
than any dilution of such holders' interests in the new entity), and (b)
following such merger, conversion, consolidation, amalgamation, replacement,
conveyance, transfer or lease, neither the Trust nor such successor entity will
be required to register as an investment company under the 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, the Trust shall not, except
with the consent of holders of 100% in Liquidation Amount of the Trust
Securities, consolidate, amalgamate, merge or convert with or into, or be
replaced by or convey, transfer or lease its properties and assets as an
entirety or substantially as an entirety to any other entity or permit any other
entity to consolidate, amalgamate, merge or convert with or into, or replace it
if such consolidation, amalgamation, merger, conversion, replacement,
conveyance, transfer or lease would cause the Trust or the successor entity not
to be classified as a grantor trust for United States federal income tax
purposes.
 
     Voting Rights; Amendment of the Declaration. Except as provided below and
under "-- Mergers, Conversions, Consolidations, Amalgamations or Replacements of
the Trust" and "-- Description of New Guarantee -- Amendments and Assignment"
and as otherwise required by law and the Declaration, the holders of the Capital
Securities will have no voting rights.
 
     The Declaration 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 Trust Securities (i) to cure any ambiguity, correct or supplement
any provisions in the Declaration that may be inconsistent with any other
provision, or to make any other provisions with respect to matters or questions
arising under the Declaration, which shall not be inconsistent with the other
provisions of the Declaration, or (ii) to modify, eliminate or add to any
provisions of the Declaration to such extent as shall be necessary to ensure
that the Trust will be classified for United States federal income tax purposes
as a grantor trust at all times that any Trust Securities are outstanding or to
ensure that the Trust will not be required to register as an "investment
company" under the Investment Company Act; provided, however, that in the case
of clause (i), such action shall not adversely affect in any material respect
the interests of the holders of the Trust Securities, and any amendments of the
Declaration shall become effective when notice thereof is given to the holders
of the Trust Securities. The Declaration may be amended by the Issuer Trustees
and the Corporation (i) with the consent of holders
 
                                       45
<PAGE>   47
 
representing a majority (based upon Liquidation Amount) of the outstanding Trust
Securities, and (ii) upon receipt by the Issuer Trustees of an opinion of
counsel experienced in such matters 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 Trust's status as a grantor trust for United
States federal income tax purposes or the Trust's exemption from status as an
"investment company" under the Investment Company Act, provided that, without
the consent of each holder of Trust Securities, the Declaration 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; it being understood that
the New Capital Securities and any Old Capital Securities which remain
outstanding after consummation of the Exchange Offer will vote together as a
single class for purposes of determining whether holders of the requisite
percentage in outstanding Liquidation Amount thereof have taken certain actions
or exercised certain rights under the Declaration.
 
     So long as any 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 such Property Trustee with respect to
the Junior Subordinated Debentures, (ii) waive certain past defaults under the
Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Junior Subordinated
Debentures or (iv) consent to any amendment, modification or termination of the
Indenture or the Junior Subordinated Debentures, where such consent shall be
required, without, in each case, obtaining the prior approval of the holders of
a majority in Liquidation Amount of all outstanding Capital Securities;
provided, however, that where a consent under the Indenture would require the
consent of each holder of Junior Subordinated Debentures affected thereby, no
such consent shall be given by the Property Trustee without the prior approval
of each holder of the Capital Securities. The Issuer Trustees shall not revoke
any action previously authorized or approved by a vote of the holders of the
Capital Securities except by subsequent vote of such holders. The Property
Trustee shall notify each holder of Capital Securities of any notice of default
with respect to the Junior Subordinated Debentures. In addition to obtaining the
foregoing approvals of such holders of the Capital 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 the Trust will not be
classified as an association taxable as a corporation for United States federal
income tax purposes on account of such action.
 
     Any required approval of holders of Capital Securities may be given at a
meeting of such holders convened for such purpose or pursuant to written
consent. The Property Trustee will cause a notice of any meeting at which
holders of Capital 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 Capital Securities in the manner set forth in the
Declaration.
 
     No vote or consent of the holders of Capital Securities will be required
for the Trust to redeem and cancel the Capital Securities in accordance with the
Declaration.
 
     Notwithstanding that holders of the Capital Securities are entitled to vote
or consent under any of the circumstances described above, any of the Capital
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.
 
     Form, Denomination, Book-Entry Procedures and Transfer. The New Capital
Securities may be represented by one or more Capital Securities in registered,
global form (collectively, the "Global New Capital Securities" and, together
with the Old Capital Securities in registered, global form, the "Global Capital
Securities"). The Global New Capital Securities will be deposited upon issuance
with the Property Trustee as custodian for DTC, in New York, New York, and
registered in the name of DTC or its nominee, in each case for credit to an
account of a direct or indirect participant in DTC as described below.
 
                                       46
<PAGE>   48
 
     Except as set forth below, the Global Capital Securities may be
transferred, in whole and not in part, only to another nominee of DTC or to a
successor of DTC or its nominee. Beneficial interests in the Global Capital
Securities may not be exchanged for Capital Securities in certificated form
except in the limited circumstances described below.
 
     DTC has advised the Trust and the Corporation that DTC is a limited-purpose
trust company created to hold securities for its participating organizations
(collectively, the "Participants") and to facilitate the clearance and
settlement of transactions in those securities between Participants through
electronic book-entry changes in accounts of its Participants. The Participants
include securities brokers and dealers (including the Initial Purchaser), banks,
trust companies, clearing corporations and certain other organizations. Access
to DTC's system is also available to other entities such as banks, brokers,
dealers and trust companies that clear through or maintain a custodial
relationship with a Participant, either directly or indirectly (collectively,
the "Indirect Participants"). Persons who are not Participants may beneficially
own securities held by or on behalf of DTC only through the Participants or the
Indirect Participants. The ownership interest and transfer of ownership interest
of each actual purchaser of each security held by or on behalf of DTC are
recorded on the records of the Participants and Indirect Participants.
 
     DTC has also advised the Trust and the Corporation that, pursuant to
procedures established by it, (i) upon deposit of the Global Capital Securities,
DTC will credit the accounts of Participants with portions of the Liquidation
Amount of the Global Capital Securities and (ii) ownership of such interests in
the Global Capital Securities will be shown on, and the transfer of ownership
thereof will be effected only through, records maintained by DTC (with respect
to the Participants) or by the Participants and the Indirect Participants (with
respect to other owners of beneficial interests in the Global Capital
Securities).
 
     Except as described below, owners of beneficial interests in the Global
Capital Securities will not have Capital Securities registered in their name,
will not receive physical delivery of Capital Securities in certificated form
and will not be considered the registered owners or holders thereof under the
Declaration for any purpose.
 
     Payments in respect of the Global Capital Security registered in the name
of DTC or its nominee will be payable by the Property Trustee to DTC in its
capacity as the registered holder under the Declaration. Under the terms of the
Declaration, the Property Trustee will treat the persons in whose names the
Capital Securities, including the Global Capital Securities, are registered as
the owners thereof for the purpose of receiving such payments and for any and
all other purposes whatsoever. Consequently, neither the Property Trustee nor
any agent thereof has or will have any responsibility or liability for (i) any
aspect of DTC's records or any Participant's or Indirect Participant's records
relating to or payments made on account of beneficial ownership interests in the
Global Capital Securities, or for maintaining, supervising or reviewing any of
DTC's records or any Participant's or Indirect Participant's records relating to
the beneficial ownership interests in the Global Capital Securities or (ii) any
other matter relating to the actions and practices of DTC or any of its
Participants or Indirect Participants. DTC has advised the Trust and the
Corporation that its current practice, upon receipt of any payment in respect of
securities such as the Global Capital Securities, is to credit the accounts of
the relevant Participants with the payment on the payment date, in amounts
proportionate to their respective holdings in Liquidation Amount of beneficial
interests in the relevant security as shown on the records of DTC unless DTC has
reason to believe it will not receive payment on such payment date. Payments by
the Participants and the Indirect Participants to the beneficial owners of the
Global Capital Securities will be governed by standing instructions and
customary practices and will be the responsibility of the Participants or the
Indirect Participants and will not be the responsibility of DTC, the Property
Trustee, the Trust or the Corporation. Neither the Trust or the Corporation nor
the Property Trustee will be liable for any delay by DTC or any of its
Participants in identifying the beneficial owners of the Global Capital
Securities, and the Trust or the Corporation and the Property Trustee may
conclusively rely on and will be protected in relying on instructions from DTC
or its nominee for all purposes.
 
     Secondary market trading activity in interests in the Global Capital
Securities will settle in immediately available funds, subject in all cases to
the rules and procedures of DTC and its Participants. Transfers between
Participants in DTC will be effected in accordance with DTC's procedures, and
will settle in same-day funds.

     DTC has advised the Trust and the Corporation that it will take any action
permitted to be taken by a holder of Capital Securities only at the direction of
one or more Participants to whose account with DTC interests in the Global
Capital Securities are credited and only in respect of such portion of the
Liquidation Amount of the Capital Securities as to which such Participant or
Participants has or have given such direction. However, if there is an Event of
Default under the Declaration, DTC reserves the right to exchange the Global
Capital Securities for Capital Securities in certificated form and to distribute
such Capital Securities to its Participants.
 
     The information in this section concerning DTC and its book-entry system
has been obtained from sources that the Trust and the Corporation believe to be
reliable, but neither the Trust nor the Corporation takes responsibility for the
accuracy thereof.
 
     A Global New Capital Security is exchangeable for New Capital Securities in
registered certificated form if (i) DTC (x) notifies the Trust that it is
unwilling or unable to continue as Depositary for the Global New Capital
Security and the Trust thereupon fails to appoint a successor Depositary within
90 days or (y) has ceased to be a clearing agency registered under the Exchange
Act, (ii) the Corporation in its sole discretion elects to cause the issuance of
the New Capital Securities in certificated form or (iii) there shall have
occurred and be continuing an Event of Default or any event which after notice
or lapse of time or both would be an Event of Default under the Declaration. In
addition, beneficial interests in a Global New Capital Security may be exchanged
for certificated New Capital Securities upon request but only upon at least 20
days' prior written notice given to the Property Trustee by or on behalf of DTC
in accordance with customary procedures. In all cases, certificated New Capital
Securities delivered in exchange for any Global New Capital Security or
beneficial interests therein will be registered in the names, and issued in any
approved denominations, requested by or on behalf of the Depositary (in
accordance with its customary procedures), unless the Property Trustee
determines otherwise in compliance with applicable law.
 
     Payment and Paying Agency. Payments in respect of the New Capital
Securities held in global form shall be made to the Depositary, which shall
credit the relevant accounts at the Depositary on the applicable Distribution
Dates or in respect of the New Capital Securities that are not held by the
Depositary, such payments shall be made by check mailed to the address of the
holder entitled thereto as such address shall appear on the register. 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. The Property Trustee will act as registrar
and transfer agent for the New Capital Securities.
 
     Registration of transfers of the New Capital Securities will be effected
without charge by or on behalf of the Trust, but upon payment of any tax or
other governmental charges that may be imposed in connection with any transfer
or exchange. The Trust will not be required to register or cause to be
registered the transfer of any New Capital Securities after they have been
called for redemption.
 
     Information Concerning the Property Trustee. The Property Trustee, other
than during the occurrence and continuance of an Event of Default, undertakes to
perform only such duties as are specifically set forth in the Declaration 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 Declaration at the request of any
holder of Trust Securities unless it is offered reasonable indemnity against the
costs, expenses and liabilities that might be incurred thereby. If no Event of
Default has occurred and is continuing and the Property Trustee is required to
decide between alternative causes of action, construe ambiguous provisions in
the Declaration or is unsure of the application of any provision of the
Declaration, and the matter is not one on which holders of the Capital
Securities or the Common Securities are entitled under the Declaration to vote,
then the Property Trustee shall take such action as is directed by the
Corporation and, if not so directed, shall
 
                                       48
<PAGE>   50
 
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.
 
     The Corporation or its affiliates may maintain certain accounts and other
banking relationships with the Property Trustee and its affiliates in the
ordinary course of business.
 
     Miscellaneous. The Administrative Trustees are authorized and directed to
conduct the affairs of and to operate the Trust in such a way that the Trust
will not be deemed to be an "investment company" required to be registered under
the Investment Company Act or classified as an association taxable as a
corporation for United States federal income tax purposes and so that the 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 the Trust or the
Declaration, 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
Trust Securities.
 
     Holders of the Trust Securities have no preemptive or similar rights.
 
     The Trust may not borrow money, issue debt, execute mortgages or pledge any
of its assets.
 
DESCRIPTION OF NEW JUNIOR SUBORDINATED DEBENTURES
 
     The Old Junior Subordinated Debentures were issued and the New Junior
Subordinated Debentures will be issued as a separate series under the Indenture.
The Indenture has been qualified under the Trust Indenture Act. This summary of
certain terms and provisions of the Junior Subordinated Debentures and the
Indenture does not purport to be complete and, where reference is made to
particular provisions of the Indenture, such provisions, including the
definitions of certain terms, some of which are not otherwise defined herein,
are qualified in their entirety by reference to all of the provisions of the
Indenture and those terms made a part of the Indenture by the Trust Indenture
Act.
 
     General. Concurrently with the issuance of the Old Capital Securities, the
Trust invested the proceeds thereof, together with the consideration paid by the
Corporation for the Common Securities, in Old Junior Subordinated Debentures
issued by the Corporation.
 
     The New Junior Subordinated Debentures will bear interest at the annual
rate of 9.35% of the principal amount thereof, payable semi-annually in arrears
on June 15 and December 15 of each year (each, an "Interest Payment Date"),
commencing June 15, 1997, to the person in whose name each New Junior
Subordinated Debenture is registered, subject to certain exceptions, at the
close of business on the 15th day of the month immediately preceding the month
in which the relevant payment date falls. It is anticipated that, until the
liquidation, if any, of the Trust, each New Junior Subordinated Debenture will
be held in the name of the Property Trustee in trust for the benefit of the
holders of the Trust Securities. The amount of interest payable for any period
will be computed on the basis of a 360-day year of twelve 30-day months and, for
any period of less than a full calendar month, the number of days elapsed in
such month. In the event that any date on which interest is payable on the New
Junior 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 next succeeding Business Day falls in the next
succeeding calendar year, then 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
9.35% thereof, compounded semi-annually. 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 herein), as applicable.
 
     The New Junior Subordinated Debentures will be issued in denominations of
$1,000 and integral multiples thereof. The New Junior Subordinated Debentures
will mature on June 15, 2027 (the "Stated Maturity Date").
 
                                       49
<PAGE>   51
 
     The New Junior Subordinated Debentures will rank pari passu with the Old
Junior Subordinated Debentures and with all Other Debentures and will be
unsecured and subordinate and rank junior in right of payment to all Senior
Indebtedness to the extent and in the manner set forth in the Indenture. See "--
Subordination." The Corporation is a holding company and almost all of the
operating assets of the Corporation and its consolidated subsidiaries are owned
by such subsidiaries. The Corporation relies primarily on dividends from such
subsidiaries to meet its obligations. The Corporation is a legal entity separate
and distinct from its subsidiaries. The principal sources of the Corporation's
income are dividends, interest and fees from its subsidiaries. The Banks are
subject to certain restrictions imposed by federal law on any extensions of
credit to, and certain other transactions with, the Corporation and certain
other affiliates, and on investments in stock or other securities thereof. Such
restrictions prevent the Corporation and such other affiliates from borrowing
from the Banks unless the loans are secured by various types of collateral.
Further, such secured loans, other transactions and investments by any of the
Banks are generally limited in amount as to the Corporation and as to each of
such other affiliates to 10% of such Bank's capital and surplus and as to the
Corporation and all of such other affiliates to an aggregate of 20% of such
Bank's capital and surplus. In addition, payment of dividends to the Corporation
by the Banks is subject to ongoing review by banking regulators and is subject
to various statutory limitations and in certain circumstances requires approval
by banking regulatory authorities. 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 the subsidiary, except to the extent
the Corporation may itself be recognized as a creditor of that subsidiary.
Accordingly, the New Junior Subordinated Debentures will be effectively
subordinated to all existing and future liabilities of the Corporation's
subsidiaries, and holders of New Junior Subordinated Debentures should look only
to the assets of the Corporation for payments on the New Junior Subordinated
Debentures. The Indenture does not limit the incurrence or issuance of other
secured or unsecured debt of the Corporation, including Senior Indebtedness. See
"-- Subordination" below.
 
     Form, Registration and Transfer. If the Junior Subordinated Debentures are
distributed to the holders of the Trust Securities, the New Junior Subordinated
Debentures may be represented by one or more global certificates registered in
the name of Cede & Co. as the nominee of DTC. The depositary arrangements for
such New Junior Subordinated Debentures are expected to be substantially similar
to those in effect for the New Capital Securities. 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 "-- Description of
New Capital Securities -- Form, Denomination, Book-Entry Procedures and
Transfer."
 
     Payment and Paying Agents. Payment of principal of and premium, if any, and
interest on New 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, except that
at the option of the Corporation payment of any interest may be made, except in
the case of New Junior Subordinated Debentures in global form, (i) by check
mailed to the address of the Person entitled thereto as such address shall
appear in the register for New Junior Subordinated Debentures or (ii) by
transfer to an account maintained by the Person entitled thereto as specified in
such register, provided that proper transfer instructions have been received by
the relevant Record Date. Payment of any interest on any New Junior Subordinated
Debenture will be made to the Person in whose name such New Junior Subordinated
Debenture is registered at the close of business on the 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 the New 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 New 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 New Junior Subordinated
Debenture shall thereafter look, as a general unsecured creditor, only to the
Corporation for payment thereof.
 
                                       50
<PAGE>   52
 
     Option to Extend Interest Payment Date. So long as no Debenture Event of
Default has occurred and is continuing, the Corporation will have the right
under the Indenture at any time during the term of the Junior Subordinated
Debentures to defer the payment of interest at any time or from time to time for
a period not exceeding 10 consecutive semiannual periods with respect to each
Extension Period, provided that no Extension Period shall end on a date other
than an Interest Payment Date or extend beyond the Stated Maturity Date. At the
end of an Extension Period, the Corporation must pay all interest then accrued
and unpaid (together with interest thereon accrued at the annual rate of 9.35%,
compounded semiannually, to the extent permitted by applicable law ("Compounded
Interest")). During an Extension Period, interest will continue to accrue and,
if the Junior Subordinated Debentures have been distributed to holders of the
Trust Securities, holders of Junior Subordinated Debentures (or holders of the
Trust Securities while Trust Securities are outstanding) will be required to
accrue such deferred interest income for United States federal income tax
purposes prior to the receipt of cash attributable to such income. See "Certain
Federal Income Tax Considerations -- Interest Income and Original Issue
Discount."
 
     During any such Extension Period, the Corporation may not (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
(other than (a) dividends or distributions in shares of, or options, warrants or
rights to subscribe for or purchase shares of, common stock of the Corporation,
(b) any declaration of a dividend in connection with the implementation of a
stockholders' rights plan, or the issuance of stock under any such plan in the
future, or the redemption or repurchase of any such rights pursuant thereto, (c)
as a result of a reclassification of the Corporation's capital stock or the
exchange or conversion of one class or series of the Corporation's capital stock
for another class or series of the Corporation's capital stock, (d) the purchase
of fractional interests in shares of the Corporation's capital stock pursuant to
the conversion or exchange provisions of such capital stock or the security
being converted or exchanged, (e) purchases of common stock related to the
issuance of common stock or rights under any of the Corporation's benefit plans
for its directors, officers or employees or any of the Corporation's dividend
reinvestment plans and (f) purchases of Common Stock in connection with the
satisfaction by the Guarantor of its obligations pursuant to any contract or
security requiring the Guarantor to purchase shares of Common Stock), or (ii)
make any payment of principal, interest or premium, if any, on or repay,
repurchase or redeem any debt securities of the Corporation (including any Other
Debentures) that rank pari passu with or junior in right of payment to the
Junior Subordinated Debentures or (iii) make any guarantee payments (other than
payments under the Guarantee) with respect to any guarantee by the Corporation
of the debt securities of any subsidiary of the Corporation (including any Other
Guarantees) if such guarantee ranks pari passu with or junior in right of
payment to the Junior Subordinated Debentures.
 
     Prior to the termination of any such Extension Period, the Corporation may
further extend such Extension Period, provided that such extension does not
cause such Extension Period to exceed 10 consecutive semiannual periods, end on
a date other than an Interest Payment Date or extend beyond the Stated Maturity
Date. Upon the termination of any such Extension Period and the payment of all
amounts then due on any Interest Payment Date, 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 of any Extension Period (or an
extension thereof) at least five Business Days prior to the earlier of (i) the
date the Distributions on the Trust Securities would have been payable except
for the election to begin or extend such Extension Period or (ii) the date the
Administrative Trustees are required to give notice to any securities exchange
or to holders of Capital Securities of the record date or the date such
Distributions are payable, but in any event not less than five Business Days
prior to such record date. The Debenture Trustee shall give notice of the
Corporation's election to begin or extend a new Extension Period to the holders
of the Capital Securities. There is no limitation on the number of times that
the Corporation may elect to begin an Extension Period.
 
     Optional Prepayment. The Junior Subordinated Debentures will be prepayable,
in whole or in part, at the option of the Corporation, on or after March 1, 2007
(the "Initial Optional Prepayment Date"), subject to the Corporation having
received prior approval of the Federal Reserve, if then required under
applicable capital
 
                                       51
<PAGE>   53
 
guidelines or policies of the Federal Reserve, at a prepayment price (the
"Optional Prepayment Price") equal to the percentage of the outstanding
principal amount of the Junior Subordinated Debentures specified below, plus, in
each case, accrued and unpaid interest thereon to the date of prepayment if
redeemed during the 12-month period beginning March 1 of the years indicated
below:

     Special Event Prepayment. If a Special Event shall occur and be continuing,
the Corporation may, at any time prior to the Initial Optional Prepayment Date,
at its option and subject to receipt of prior approval of the Federal Reserve if
then required under applicable capital guidelines or policies of the Federal
Reserve, prepay the Junior Subordinated Debentures in whole (but not in part) at
any time within 90 days of the occurrence of such Special Event, at a prepayment
price (the "Special Event Prepayment Price") equal to the greater of (i) 100% of
the principal amount of such Junior Subordinated Debentures or (ii) the sum, as
determined by a Quotation Agent, of the present values of the principal amount
and premium payable as part of the Optional Prepayment Price with respect to an
optional redemption of such Junior Subordinated Debentures on the Initial
Optional Prepayment Date, together with scheduled payments of interest from the
prepayment date to the Initial Optional Prepayment Date, in each case discounted
to the prepayment date on a semi-annual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus, in
either case, accrued and unpaid interest thereon to the date of prepayment.
 
     A "Special Event" means a Tax Event or a Regulatory Capital Event (as
defined below), as the case may be.
 
     A "Tax Event" means the receipt by the Corporation and the Trust of an
opinion of a nationally recognized tax counsel experienced in such matters to
the effect that, as a result of any amendment to, or change (including any
announced prospective 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 pronouncement or decision is announced on or after
March 25, 1997, there is more than an insubstantial risk that (i) the Trust 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 Junior
Subordinated Debentures, (ii) interest payable by the Corporation on the 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) the Trust 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.
 
     A "Regulatory Capital Event" means that the Corporation shall have received
an opinion of independent bank regulatory counsel experienced in such matters to
the effect that, as a result of (a) any amendment to, or change (including any
announced prospective change) in, the laws (or any regulations thereunder) of
the United States or any rules, guidelines or policies of the Federal Reserve or
(b) any official administrative pronouncement or judicial decision interpreting
or applying such laws or regulations, which amendment or change is effective or
such pronouncement or decision is announced on or after March 25, 1997, the
Capital Securities do not constitute, or within 90 days of the date of such
opinion, will not constitute, Tier 1 Capital (or its then equivalent); provided,
however, that a Regulatory Capital Event shall not occur by reason of the
 
                                       52
<PAGE>   54
 
use of the proceeds of the Junior Subordinated Debentures by the Corporation
contemplated herein, and the distribution of the Junior Subordinated Debentures
in connection with the liquidation of the Trust by the Corporation shall not in
and of itself constitute a Regulatory Capital Event unless such liquidation
shall have occurred in connection with a Tax Event.
 
     "Adjusted Treasury Rate" means, with respect to any prepayment date, the
rate per annum equal to (i) the yield, under the heading which represents the
average for the immediately prior week, appearing in the most recently published
statistical release designated "H.15(519)" or any successor publication which is
published weekly by the Federal Reserve and which established yields on actively
traded United States Treasury securities adjusted to constant maturity under the
caption "Treasury Constant Maturities," for the maturity date corresponding to
the Initial Optional Prepayment Date (if no maturity date is within three months
before or after the Initial Optional Prepayment Date, yields for the two
published maturities most closely corresponding to the Initial Optional
Prepayment Date shall be interpolated and the Adjusted Treasury Rate shall be
interpolated or extrapolated from such yields on a straight-line basis, rounding
to the nearest month) or (ii) if such release (or any successor release) is not
published during the week preceding the calculation date or does not contain
such yields, the rate per annum equal to the semi-annual equivalent yield to
maturity of the Comparable Treasury Issue, assuming a price for the Comparable
Treasury Issue (expressed as a percentage of its principal amount) equal to the
Comparable Treasury Price for such prepayment date plus, in either case (A)
1.35% if such prepayment date occurs on or prior to March 1, 1998 and (B) .50%
in all other cases.
 
     "Comparable Treasury Issue" means the United States Treasury security
selected by the Quotation Agent as having a maturity date corresponding to the
Initial Optional Prepayment Date that would be utilized at the time of selection
and in accordance with customary financial practice, in pricing new issues of
corporate debt securities with a maturity date corresponding to the Initial
Optional Prepayment Date. If no United States Treasury security has a maturity
date which is within three months before or after the Initial Optional
Prepayment Date, the two most closely corresponding United States Treasury
securities shall be used as the Comparable Treasury Issue, and the calculation
of the Adjusted Treasury Rate pursuant to clause (ii) of the definition thereof
shall be interpolated or extrapolated on a straight-line basis, rounding to the
nearest month.
 
     "Quotation Agent" means the Reference Treasury Dealer appointed by the
Corporation. "Reference Treasury Dealer" means a nationally recognized U.S.
Government securities dealer in New York City selected by the Corporation.
 
     "Comparable Treasury Price" means, with respect to any prepayment date, (i)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount) on the third
Business Day preceding such prepayment date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (ii) if such release (or any successor release) is not
published or does not contain such prices on such Business Day, (A) the average
of five Reference Treasury Dealer Quotations for such prepayment date, after
excluding the highest and lowest such Reference Treasury Dealer Quotations, or
(B) if the Debenture Trustee obtains fewer than three such Reference Treasury
Dealer Quotations, the average of all such Quotations.
 
     "Reference Treasury Dealer Quotations" means, with respect to each
Reference Treasury Dealer and any prepayment date, the average, as determined by
the Debenture Trustee, of the bid and asked prices for the Comparable Treasury
Issue (expressed in each case as a percentage of its principal amount) quoted in
writing to the Debenture Trustee by such Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third Business Day preceding such prepayment date.
 
     "Additional Sums" means such additional amounts as may be necessary in
order that the amount of Distributions then due and payable by the Trust on the
outstanding Capital Securities and Common Securities shall not be reduced as a
result of any additional taxes, duties or other governmental charges to which
the Trust has become subject as a result of a Tax Event.
 
                                       53
<PAGE>   55
 
     Notice of any prepayment 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 prepaid at its registered address. Unless the Corporation
defaults in payment of the prepayment price, on and after the prepayment date
interest ceases to accrue on such Junior Subordinated Debentures called for
prepayment.
 
     If the Trust 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 Junior Subordinated Debentures the Additional Sums.
 
     Certain Covenants of the Corporation. The Corporation will also covenant
that it will not (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 (other than (a) dividends or distributions in
shares of, or options, warrants or rights to subscribe for or purchase shares
of, common stock of the Corporation, (b) any declaration of a dividend in
connection with the implementation of a stockholders' rights plan, or the
issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto, (c) as a result of a
reclassification of the Corporation's capital stock or the exchange or
conversion of one class or series of the Corporation's capital stock for another
class or series of the Corporation's capital stock, (d) the purchase of
fractional interests in shares of the Corporation's capital stock pursuant to
the conversion or exchange provisions of such capital stock or the security
being converted or exchanged, (e) purchases of common stock related to the
issuance of common stock or rights under any of the Corporation's benefit plans
for its directors, officers or employees or any of the Corporation's dividend
reinvestment plans and (f) purchases of Common Stock in connection with the
satisfaction by the Guarantor of its obligations pursuant to any contract or
security requiring the Guarantor to purchase shares of Common 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 Debentures)
that rank pari passu with or junior in right of payment to the Junior
Subordinated Debentures or (iii) make any guarantee payments (other than
payments under the Guarantee) with respect to any guarantee by the Corporation
of the debt securities of any subsidiary of the Corporation (including under
Other Guarantees) if such guarantee ranks pari passu or junior in right of
payment to the Junior Subordinated Debentures if at such time (1) an Event of
Default shall have occurred and be continuing, (2) there shall have occurred any
event of which the Corporation has actual knowledge that (x) is, or with the
giving of notice or the lapse of time, or both, would be, a Debenture Event of
Default and (y) in respect of which the Corporation shall not have taken
reasonable steps to cure, (3) if such Junior Subordinated Debentures are held by
the Trust, the Corporation shall be in default with respect to its payment of
any obligations under the Guarantee or (4) the Corporation shall have given
notice of its election of an Extension Period as provided in the Indenture and
shall not have rescinded such notice, and such Extension Period, or any
extension thereof, shall have commenced and be continuing.
 
     The Corporation will also covenant, for so long as the Trust Securities
remain outstanding, (i) to maintain 100 percent ownership of the Common
Securities; provided, however, that any permitted successor of the Corporation
under the Indenture may succeed to the Corporation's ownership of the Common
Securities, (ii) to use its reasonable efforts to cause the Trust (a) to remain
a statutory business trust, except in connection with the distribution of Junior
Subordinated Debentures to the holders of Trust Securities in liquidation of the
Trust, the redemption of all of the Trust Securities of the Trust, or certain
mergers, consolidations or amalgamations, each as permitted by the Declaration,
and (b) to continue not to be classified as an association taxable as a
corporation or a partnership for United States federal income tax purposes and
(iii) to use its reasonable efforts to cause each holder of Trust Securities to
be treated as owning an undivided beneficial interest in the Junior Subordinated
Debentures.
 
     Debenture Events of Default. The Indenture provides that any one or more of
the following described events with respect to the Junior Subordinated
Debentures constitutes a "Debenture Event of Default" (whatever the reason for
such Debenture Event of Default and whether it shall be voluntary or involuntary
or
 
                                       54
<PAGE>   56
 
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) failure for 30 days to pay any interest on the Junior Subordinated
     Debentures or any Other Debentures, when due (subject to the deferral of
     any due date in the case of an Extension Period); or
 
          (ii) failure to pay any principal or premium, if any, on the Junior
     Subordinated Debentures or any Other Debentures when due whether at
     maturity, upon redemption, by declaration of acceleration of maturity or
     otherwise; 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 Junior Subordinated
     Debentures; or
 
          (iv) certain events in bankruptcy, insolvency or reorganization of the
     Corporation.
 
     The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debentures have, subject to certain exceptions, the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Debenture Trustee. The Debenture Trustee or the holders of not
less than 25% in aggregate outstanding principal amount of the Junior
Subordinated Debentures may declare the principal due and payable immediately
upon a Debenture Event of Default. The holders of a majority in aggregate
outstanding principal amount of the Junior Subordinated Debentures may annul
such declaration and waive the default if the default (other than the nonpayment
of the principal of the Junior Subordinated Debentures which has become due
solely by such acceleration) 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.
 
     The holders of a majority in aggregate outstanding principal amount of the
Junior Subordinated Debentures affected thereby may, on behalf of the holders of
all the Junior Subordinated Debentures, waive any past default except a default
in the payment of principal of, or premium, if any, on or interest (unless such
default has been cured and a sum sufficient to pay all matured installments of
interest and premium, if any, 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.
 
     The Indenture requires the annual filing by the Corporation with the
Debenture Trustee of a certificate as to the absence of certain defaults under
the Indenture.
 
     The Indenture provides that the Debenture Trustee may withhold notice of a
Debenture Event of Default from the holders of the Junior Subordinated
Debentures (except a Debenture Event of Default in payment of principal of, or
of interest or premium on, the Junior Subordinated Debentures) if the Debenture
Trustee considers it in the interest of such holders to do so.
 
     Enforcement of Certain Rights by Holders of New Capital Securities. If a
Debenture Event of Default shall have occurred and be continuing and shall be
attributable to the failure of the Corporation to pay interest or premium, if
any, on or principal of the New Junior Subordinated Debentures on the due date,
a holder of New Capital Securities may institute 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
Capital Securities. Notwithstanding any payments made to a holder of New Capital
Securities by the Corporation in connection with a Direct Action, the
Corporation shall remain obligated to pay the principal of or premium, if any,
or interest on the New Junior Subordinated Debentures, and the Corporation shall
be subrogated to the rights of the holder of such New Capital Securities with
respect to payments on the New Capital Securities to the extent of any payments
made by the Corporation to such holder in any Direct Action.
 
     The holders of the New Capital 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 New Junior Subordinated Debentures. See "--
Description of New Capital Securities -- Events of Default; Notice."
 
                                       55

     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 as an entirety or
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 as an entirety or 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; (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; and (iii) certain other conditions as prescribed in 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.
 
     Modification of the Indenture. From time to time the Corporation and the
Debenture Trustee may, without the consent of the holders 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 Junior Subordinated Debentures). The Indenture contains
provisions permitting the Corporation and the Debenture Trustee, with the
consent of the holders of a majority in principal amount of the Junior
Subordinated Debentures, to modify the Indenture in a manner affecting the
rights of the holders of Junior Subordinated Debentures; provided that no such
modification may, without the consent of the holders of each outstanding Junior
Subordinated Debenture so affected, (i) change the Stated Maturity Date, or
reduce the principal amount of the Junior Subordinated Debentures 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 the holders of
which are required to consent to any such modification of the Indenture.
 
     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 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 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 Date, 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.
 
     Subordination. In the Indenture, the Corporation has covenanted and agreed
that any Junior Subordinated Debentures issued thereunder will be subordinate
and junior in right of payment to all Senior Indebtedness to the extent provided
in the Indenture. Upon any payment or distribution of assets to creditors upon
any liquidation, dissolution, winding up, reorganization, assignment for the
benefit of creditors, marshalling of assets or any bankruptcy, insolvency, debt
restructuring or similar proceedings in connection with any insolvency or
bankruptcy proceeding of the Corporation, all Senior Indebtedness must be paid
in full before the holders of Junior Subordinated Debentures will be entitled to
receive or retain any payment in respect thereof.
 
     In the event of the acceleration of the maturity of Junior Subordinated
Debentures, the holders of all Senior Indebtedness outstanding at the time of
such acceleration will first be entitled to receive payment in full of such
Senior Indebtedness before the holders of Junior Subordinated Debentures will be
entitled to receive or retain any payment in respect of the Junior Subordinated
Debentures.
 
     No payments on account of principal or premium, if any, or interest, if
any, in respect of the Junior Subordinated Debentures may be made if there shall
have occurred and be continuing a default in any
 
                                       56
<PAGE>   58
 
payment with respect to Senior Indebtedness, or an event of default with respect
to any Senior Indebtedness resulting in the acceleration of the maturity
thereof, or if any judicial proceeding shall be pending with respect to any such
default.
 
     "Senior Indebtedness" shall mean all Indebtedness for Money Borrowed,
whether outstanding on the date of execution of the Indenture or thereafter
created, assumed or incurred, except Indebtedness Ranking on a Parity with the
Junior Subordinated Debentures or Indebtedness Ranking Junior to the Junior
Subordinated Debentures, and any deferrals, renewals or extensions of such
Senior Indebtedness.
 
     "Indebtedness for Money Borrowed" shall mean (i) any obligation of, or any
obligation guaranteed by, the Corporation for the repayment of borrowed money,
whether or not evidenced by bonds, debentures, notes or other written
instruments and any deferred obligation for the payment of the purchase price of
property or assets acquired other than in the ordinary course of business and
(ii) all indebtedness of the Corporation for claims in respect of derivative
products such as interest and foreign exchange rate contracts, commodity
contracts and similar arrangements, whether outstanding on the date of execution
of the Indenture or thereafter created, assumed or incurred. For purposes of
this definition "claim" shall have the meaning assigned in Section 101(5) of the
Bankruptcy Code of 1978, as amended and in effect on the date of the execution
of the Indenture.
 
     "Indebtedness Ranking on Parity with the Junior Subordinated Debentures"
shall mean (i) Indebtedness for Money Borrowed, whether outstanding on the date
of execution of the Indenture or thereafter created, assumed or incurred, to the
extent such indebtedness specifically by its terms ranks equally with and not
prior to the Junior Subordinated Debentures in the right of payment upon the
happening of the dissolution or winding-up or liquidation or reorganization of
the Corporation and (ii) all other debt securities, and guarantees in respect of
those debt securities, issued to any other trust, or a trustee of such trust,
partnership or other entity affiliated with the Corporation that is a financing
vehicle of the Corporation (a "financing entity") in connection with the
issuance by such financing entity of equity securities or other securities
guaranteed by the Corporation pursuant to an instrument that ranks pari passu
with or junior in right of payment to the Guarantee.
 
     "Indebtedness Ranking Junior to the Junior Subordinated Debentures" shall
mean any Indebtedness for Money Borrowed, whether outstanding on the date of
execution of the Indenture or thereafter created, assumed or incurred, to the
extent such indebtedness specifically by its terms ranks junior to and not
equally with or prior to the Junior Subordinated Debentures (and any other
Indebtedness Ranking on a Parity with the Junior Subordinated Debentures) in
right of payment upon the happening of the dissolution or winding-up or
liquidation or reorganization of the Corporation. The securing of any
Indebtedness for Money Borrowed, otherwise constituting Indebtedness Ranking on
a Parity with the Junior Subordinated Debentures or Indebtedness Ranking Junior
to the Junior Subordinated Debentures, as the case may be, shall not be deemed
to prevent such Indebtedness for Money Borrowed from constituting Indebtedness
Ranking on a Parity with the Junior Subordinated Debentures or Indebtedness
Ranking Junior to the Junior Subordinated Debentures, as the case may be.
 
     The Corporation is a non-operating holding company and almost all of the
operating assets of the Corporation are owned by the Corporation's subsidiaries.
The Corporation relies primarily on dividends from such subsidiaries to meet its
obligations for payment of principal and interest on its outstanding debt
obligations and corporate expenses. The Corporation is a legal entity separate
and distinct from its banking and non-banking affiliates. The principal sources
of the Corporation's income are dividends, interest and fees from its banking
and non-banking affiliates. The Banks are subject to certain restrictions
imposed by federal law on any extensions of credit to, and certain other
transactions with, the Corporation and certain other affiliates, and on
investments in stock or other securities thereof. Such restrictions prevent the
Corporation and such other affiliates from borrowing from the Banks unless the
loans are secured by various types of collateral. Further, such secured loans,
other transactions and investments by any of the Banks are generally limited in
amount as to the Corporation and as to each of such other affiliates to 10% of
such Bank's capital and surplus and as to the Corporation and all of such other
affiliates to an aggregate of 20% of such Bank's capital and surplus. In
addition, payment of dividends to the Corporation by the subsidiary banks is
subject to ongoing
 
                                       57
<PAGE>   59
 
review by banking regulators and is subject to various statutory limitations and
in certain circumstances requires approval by banking regulatory authorities.
Accordingly, the New Junior Subordinated Debentures will be effectively
subordinated to all existing and future liabilities of the Corporation's
subsidiaries. Holders of New Junior Subordinated Debentures should look only to
the assets of the Corporation for payments of interest and principal and
premium, if any.
 
     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 New 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
 
     Following the Exchange Offer and the qualification of the Indenture under
the Trust Indenture Act, the Debenture Trustee shall have and be subject to all
the duties and responsibilities specified with respect to an indenture trustee
under the Trust Indenture Act. Subject to such provisions, the Debenture Trustee
is under no obligation to exercise any of the powers vested in it by the
Indenture at the request of any holder of Junior Subordinated Debentures, unless
offered reasonable indemnity by such holder against the costs, expenses and
liabilities which might be incurred thereby. The Debenture Trustee is not
required to expend or risk its own funds or otherwise incur personal financial
liability in the performance of its duties if the Debenture Trustee reasonably
believes that repayment or adequate indemnity is not reasonably assured to it.
 
     The Corporation or its affiliates may maintain certain accounts and other
banking relationships with the Debenture Trustee and its affiliates in the
ordinary course of business.
 
DESCRIPTION OF NEW GUARANTEE
 
     The Old Guarantee was executed and delivered by the Corporation
concurrently with the issuance by the Trust of the Old Capital Securities for
the benefit of the holders from time to time of the Old Capital Securities.
Promptly after the Expiration Date, the New Guarantee will be issued by the
Corporation for the benefit of the holders from time to time of the New Capital
Securities. The New Guarantee has been qualified under the Trust Indenture Act.
This summary of certain provisions of the New Guarantee does not purport to be
complete and is subject to, and qualified in its entirety by reference to, all
of the provisions of the New Guarantee, including the definitions therein of
certain terms, and the Trust Indenture Act. The Guarantee Trustee will hold the
New Guarantee for the benefit of the holders of the New Capital 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 New Capital Securities, as and when due,
regardless of any defense, right of set-off or counterclaim that the Trust may
have or assert other than the defense of payment. The following payments with
respect to the New Capital Securities, to the extent not paid by or on behalf of
the Trust (the "Guarantee Payments"), will be subject to the New Guarantee: (i)
any accumulated and unpaid Distributions required to be paid on New Capital
Securities, to the extent the Trust has funds on hand legally available
therefor, (ii) the applicable Redemption Price with respect to any New Capital
Securities called for redemption, to the extent that the Trust has funds on hand
legally available therefor, or (iii) upon a voluntary or involuntary termination
and liquidation of the Trust (unless the New Junior Subordinated Debentures are
distributed to holders of the New Capital Securities), the lesser of (a) the
Liquidation Distribution and (b) the amount of assets of the Trust remaining
available for distribution to holders of New Capital Securities. 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 New
Capital Securities or by causing the Trust to pay such amounts to such holders.
 
                                       58
<PAGE>   60
 
     The New Guarantee will rank subordinate and junior in right of payment to
all Senior Indebtedness to the extent provided therein. See "-- Status." 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 New Guarantee 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. See "-- Description of New Junior Subordinated
Debentures -- General." The New Guarantee 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 indenture that the
Corporation may enter into in the future or otherwise.
 
     The Corporation will, through the New Guarantee, the Declaration, the New
Junior Subordinated Debentures and the Indenture, taken together, fully,
irrevocably and unconditionally guarantee all of the Trust's obligations under
the New Capital 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
Trust's obligations under the New Capital Securities. See "Relationship Among
the New Capital Securities, the New Junior Subordinated Debentures and the New
Guarantee."
 
     Status. The New Guarantee will constitute an unsecured obligation of the
Corporation and will rank subordinate and junior in right of payment to all
Senior indebtedness in the same manner as the New Junior Subordinated
Debentures.
 
     The New Guarantee will rank pari passu with the Junior Subordinated
Debentures and with the Old Guarantee and with all Other Guarantees (if any)
issued by the Corporation with respect to capital securities (if any) issued by
Other Trusts. The New Guarantee will constitute a guarantee of payment and not
of collection (i.e., the guaranteed party may institute a legal proceeding
directly against the Corporation to enforce its rights under the New Guarantee
without first instituting a legal proceeding against any other person or
entity). The New Guarantee will be held for the benefit of the holders of the
New Capital Securities. The New Guarantee will not be discharged except by
payment of the Guarantee Payments in full to the extent not paid by the Trust or
upon distribution to the holders of the New Capital Securities of the New Junior
Subordinated Debentures. The New Guarantee does not place 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.
 
     Events of Default. An event of default under the New Guarantee will occur
upon the failure of the Corporation to perform any of its payment or other
obligations thereunder. The holders of a majority in Liquidation Amount of the
New Capital Securities will 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 New Guarantee or to direct the exercise of any trust or power
conferred upon the Guarantee Trustee under the New Guarantee.
 
     Any holder of the New Capital Securities may institute a legal proceeding
directly against the Corporation to enforce its rights under the New Guarantee
without first instituting a legal proceeding against the Trust, the Guarantee
Trustee or any other person or entity.
 
     The Corporation, as guarantor, will be 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 New
Guarantee.
 
     Amendments and Assignment. Except with respect to any changes that do not
materially adversely affect the rights of holders of the New Capital Securities
(in which case no vote will be required), the New Guarantee may not be amended
without the prior approval of the holders of a majority of the Liquidation
Amount of such outstanding New Capital Securities. The manner of obtaining any
such approval will be as set forth under "-- Description of New Capital
Securities -- Voting Rights; Amendment of the Declaration." All
 
                                       59
<PAGE>   61
 
guarantees and agreements contained in the New Guarantee shall bind the
successors, assigns, receivers, trustees and representatives of the Corporation
and shall inure to the benefit of the holders of the New Capital Securities then
outstanding.
 
     Termination. The New Guarantee will terminate and be of no further force
and effect upon full payment of the applicable Redemption Price of the New
Capital Securities, upon full payment of the Liquidation Amount payable upon
liquidation of the Trust or upon distribution of the New Junior Subordinated
Debentures to the holders of the New Capital Securities. The New Guarantee will
continue to be effective or will be reinstated, as the case may be, if at any
time any holder of the New Capital Securities must restore payment of any sums
paid under the New Capital Securities or the New 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 the New Guarantee, will undertake to perform only such duties as
are specifically set forth in the New Guarantee and, in case a default with
respect to the New Guarantee has occurred, 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 the New Guarantee at
the request of any holder of New Capital Securities, unless offered reasonable
indemnity against the costs, expenses and liabilities which might be incurred
thereby. The Guarantee Trustee is not required to expend or risk its own funds
or otherwise incur personal financial liability in the performance of its duties
if it reasonably believes that repayment or adequate indemnity is not reasonably
assured to it.
 
     The Corporation or its affiliates may maintain certain accounts and other
banking relationships with the Guarantee Trustee and its affiliates in the
ordinary course of business.
 
     Governing Law. The New Guarantee will be governed by, and construed in
accordance with, the internal laws of the State of New York.
 
                         DESCRIPTION OF OLD SECURITIES
 
     The terms of the Old Securities are identical in all material respects to
the New Securities, except that (i) the Old Securities have not been registered
under the Securities Act, are subject to certain restrictions on transfer and
are entitled to certain rights under the applicable Registration Rights
Agreement (which rights will terminate upon consummation of the Exchange Offer,
except under limited circumstances), (ii) the New Capital Securities will not
contain the $100,000 minimum Liquidation Amount transfer restriction and certain
other restrictions on transfer applicable to Old Capital Securities, (iii) the
New Capital Securities will not provide for any increase in the Distribution
rate thereon, (iv) the New Junior Subordinated Debentures will not contain the
$100,000 minimum principal amount transfer restriction and (v) the New Junior
Subordinated Debentures will not provide for any increase in the interest rate
thereon. The Old Securities provide that, in the event that a registration
statement relating to the Exchange Offer has not been filed by August 22, 1997
and been declared effective by September 21, 1997, or, in certain limited
circumstances, in the event a shelf registration statement (the "Shelf
Registration Statement") with respect to the resale of the Old Capital
Securities is not declared effective by November 3, 1997, then interest will
accrue (in addition to the stated interest rate on the Old Junior Subordinated
Debentures) at the rate of 0.25% per annum on the principal amount of the Old
Junior Subordinated Debentures and Distributions will accrue (in addition to the
stated Distribution rate on the Old Capital Securities) at the rate of 0.25% per
annum on the Liquidation Amount of the Old Capital Securities, for the period
from the occurrence of such event until such time as such required Exchange
Offer is consummated or any required Shelf Registration Statement is effective.
The New Securities are not, and upon consummation of the Exchange Offer the Old
Securities will not be, entitled to any such additional interest or
Distributions. Accordingly, holders of Old Capital Securities should review the
information set forth under "Risk Factors -- Certain Consequences of a Failure
to Exchange Old Capital Securities" and "Description of New Securities."

             RELATIONSHIP AMONG THE NEW CAPITAL SECURITIES, THE NEW
              JUNIOR SUBORDINATED DEBENTURES AND THE NEW GUARANTEE
 
FULL AND UNCONDITIONAL GUARANTEE
 
     Payments of Distributions and other amounts due on the New Capital
Securities (to the extent the Trust has funds on hand legally available for the
payment of such Distributions) will be irrevocably guaranteed by the Corporation
as and to the extent set forth under "Description of New Securities --
Description of New Guarantee." Taken together, the Corporation's obligations
under the New Junior Subordinated Debentures, the Indenture, the Declaration and
the New Guarantee will provide, in the aggregate, a full, irrevocable and
unconditional guarantee of payments of Distributions and other amounts due on
the New Capital 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
Trust's obligations under the New Capital Securities. If and to the extent that
the Corporation does not make the required payments on the New Junior
Subordinated Debentures, the Trust will not have sufficient funds to make the
related payments, including Distributions, on the New Capital Securities. The
New Guarantee will not cover any such payment when the Trust does not have
sufficient funds on hand legally available therefor. In such event, the remedy
of a holder of New Capital Securities is to institute a Direct Action. The
obligations of the Corporation under the New Guarantee will be subordinate and
junior in right of payment to all Senior Indebtedness.
 
SUFFICIENCY OF PAYMENTS
 
     As long as payments of interest and other payments are made when due on the
New Junior Subordinated Debentures, such payments will be sufficient to cover
Distributions and other payments due on the New Capital Securities, primarily
because: (i) the aggregate principal amount or Prepayment Price of the New
Junior Subordinated Debentures will be equal to the sum of the Liquidation
Amount or Redemption Price, as applicable, of the New Capital Securities and
related Common Securities; (ii) the interest rate and interest and other payment
dates on the New Junior Subordinated Debentures will match the Distribution rate
and Distribution and other payment dates for the New Capital Securities; (iii)
the Corporation shall pay for all and any costs, expenses and liabilities of the
Trust except the Trust's obligations to holders of Trust Securities under such
Trust Securities; and (iv) the Declaration provides that the Trust is not
authorized to engage in any activity that is not consistent with the limited
purposes thereof.
 
ENFORCEMENT OF RIGHTS OF HOLDERS OF CAPITAL SECURITIES
 
     A holder of any New Capital Security may institute a legal proceeding
directly against the Corporation to enforce its rights under the New Guarantee
without first instituting a legal proceeding against the Guarantee Trustee, the
Trust or any other person or entity.
 
     A default or event of default under any Senior Indebtedness would not
constitute a default or Event of Default under the Declaration. However, in the
event of payment defaults under, or acceleration of, Senior Indebtedness, the
subordination provisions of the Indenture provide that no payments may be made
in respect of the New 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 New Junior Subordinated
Debentures would constitute an Event of Default under the Declaration.
 
LIMITED PURPOSE OF THE TRUST
 
     The New Capital Securities will represent preferred beneficial interests in
the Trust, and the Trust exists for the exclusive purposes of issuing and
selling the Trust Securities, using the proceeds from the sale of the Trust
Securities to acquire the Junior Subordinated Debentures and engaging in only
those other activities necessary, advisable or incidental thereto.

RIGHTS UPON TERMINATION
 
     Unless the Junior Subordinated Debentures are distributed to holders of the
Trust Securities, upon any voluntary or involuntary termination and liquidation
of the Trust, the holders of the Trust Securities will be entitled to receive,
out of assets held by the Trust, the Liquidation Distribution in cash. See
"Description of New Securities -- Description of New Capital Securities --
Liquidation of the Trust and Distribution of New Junior Subordinated
Debentures." Upon any voluntary or involuntary liquidation or bankruptcy of the
Corporation, the Property Trustee, as holder of the New 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 premium, if any) and
interest, before any stockholders of the Corporation receive payments or
distributions. Since the Corporation will be the guarantor under the New
Guarantee and will agree to pay for all costs, expenses and liabilities of the
Trust (other than the Trust's obligations to the holders of its Trust
Securities), the positions of a holder of New Capital Securities and a holder of
New 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.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
GENERAL
 
     The following is a summary of the principal United States federal income
tax consequences of the purchase, ownership and disposition of Capital
Securities. This summary only addresses the federal income tax consequences to a
person that acquires 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, (iii) an
estate the income of which is subject to United States federal income tax
regardless of source or (iv) a trust if a court within the United States is able
to exercise primary supervision over the administration of the trust and one or
more United States trustees have the authority to control all substantial
decisions of the trust (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 Capital Securities, nor does it address the tax consequences
to (a) persons that are not United States Persons, (b) 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, (c) persons that will hold 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, (d) persons
whose functional currency is not the United States dollar or (e) persons that do
not hold Capital Securities as capital assets.
 
     The statements of law or legal conclusions set forth in this summary
constitute the opinion of Skadden, Arps, Slate, Meagher & Flom (Illinois),
special counsel to the Corporation and the Trust. An opinion of counsel is not,
however, binding on the Internal Revenue Service ("IRS") or any court. This
summary is based upon the Internal Revenue Code of 1986, as amended (the
"Code"), Treasury Regulations, IRS rulings and pronouncements and judicial
decisions as of the date hereof, 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 Capital Securities. 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 Capital Securities may
differ from the treatment described below. No rulings have been or will be
sought from the IRS regarding any matter discussed 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 CAPITAL SECURITIES, AS WELL AS THE
EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS.

CLASSIFICATION OF THE JUNIOR SUBORDINATED DEBENTURES
 
     The Corporation intends to treat the Junior Subordinated Debentures as
indebtedness of the Corporation for United States federal income tax purposes.
The following discussion assumes that the Junior Subordinated Debentures will be
so classified as indebtedness.
 
CLASSIFICATION OF THE TRUST
 
     In connection with the issuance of the Capital Securities, Skadden, Arps,
Slate, Meagher & Flom (Illinois) has rendered its opinion to the effect that,
under then current law and assuming full compliance with the terms of the
Declaration and the Indenture (and certain other documents), and based on
certain facts and assumptions contained in such opinion, the Trust will be
classified as a grantor trust and not as an association taxable as a corporation
for United States federal income tax purposes. As a result, each holder of
Capital Securities will be treated as owning an undivided interest in the Junior
Subordinated Debentures held by the Trust and each holder will be required to
include in its gross income its pro rata share of interest income (and original
issue discount income, if any) in respect of the Junior Subordinated Debentures.
 
INTEREST INCOME AND ORIGINAL ISSUE DISCOUNT
 
     United States Persons (including cash basis United States Persons) that
hold debt instruments issued with OID must generally include such OID in income
as it accrues on a constant yield method even if there is not a corresponding
receipt of cash attributable to such income. A debt instrument such as a Junior
Subordinated Debenture will generally be treated as issued with OID if the
stated interest on the instrument does not constitute "qualified stated
interest." Qualified stated interest is generally any one of a series of stated
interest payments on an instrument that are unconditionally payable at least
annually at a single fixed rate. In determining whether stated interest on an
instrument is unconditionally payable and thus constitutes qualified stated
interest, remote contingencies as to the timely payment of stated interest are
ignored. In the case of the Junior Subordinated Debentures, the Corporation has
concluded that the likelihood of its exercising its option to defer payments of
interest is remote because the exercise of such option would prevent the
Corporation from declaring dividends on any class of its stock. Accordingly, the
Corporation intends to treat the Junior Subordinated Debentures as having been
issued without OID and, therefore, United States Persons holding Capital
Securities will accrue interest income under their particular methods of
accounting (e.g., cash or accrual) rather than accruing OID on a constant yield
method.
 
     If the option to defer any payment of interest was determined not to be
"remote" or if the Corporation exercised such option, the Junior Subordinated
Debentures would be treated as issued with OID at the time of issuance or at the
time of such exercise, as the case may be, and all stated interest on the Junior
Subordinated Debentures would thereafter be treated as OID as long as the Junior
Subordinated Debentures remained outstanding. In such event, all of a United
States Person's taxable interest income in respect of the Junior Subordinated
Debentures would constitute OID that would have to be included in income on a
constant yield method before the receipt of the cash attributable to such
income, regardless of such person's method of tax accounting, and actual
distributions of stated interest would not be reported as taxable income.
Consequently, a holder of Capital Securities would be required to include such
OID in gross income even though the Corporation would not make any actual cash
payments during an Extension Period.
 
     The above conclusions are based on recently promulgated Treasury
Regulations, which have not been interpreted by any court decisions or addressed
in any ruling or other pronouncements of the IRS, and it is possible that the
IRS could take a position contrary to the conclusions herein.
 
     Corporate holders of the Capital Securities will not be entitled to a
dividends-received deduction with respect to any income recognized with respect
to the Capital Securities.
 
DISTRIBUTION OF JUNIOR SUBORDINATED DEBENTURES TO HOLDERS OF CAPITAL SECURITIES
 
     Under current law, a distribution by the Trust of the Junior Subordinated
Debentures as described under the caption "Description of Capital Securities --
Liquidation of Trust and Distribution of Junior Subordinated
 
                                       63
<PAGE>   65
 
Debentures" will be non-taxable and will result in the holder receiving directly
its pro rata share of the Junior Subordinated Debentures previously held
indirectly through the Trust, with a holding period and aggregate tax basis
equal, respectively, to the holding period and aggregate tax basis such holder
has in its Capital Securities before such distribution. A holder will accrue
interest in respect of Junior Subordinated Debentures received from the Trust in
the manner described above under "-- Interest Income and Original Issue
Discount."
 
SALES OR REDEMPTION OF CAPITAL SECURITIES
 
     Gain or loss will be recognized by a holder on a sale of Capital Securities
(including a redemption for cash) in an amount equal to the difference between
the amount realized (less any accrued interest, which would be taxable as such)
and the holder's adjusted tax basis in the Capital Securities sold or so
redeemed. Assuming the Corporation does not defer interest on the Capital
Securities by extending the interest payment periods, a holder's adjusted tax
basis in the Capital Securities generally will be its initial purchase price.
Gain or loss recognized by a holder on Capital Securities held for more than one
year will generally be taxable as long-term capital gain or loss.
 
     The Capital Securities may trade at a price that does not fully reflect the
value of accrued but unpaid interest with respect to the underlying Junior
Subordinated Debentures. If the Junior Subordinated Debentures are deemed to be
issued with OID or if the Corporation exercises its deferral option, a holder
who disposes of its Capital Securities between record dates for payments of
Distributions (and consequently does not receive a Distribution from the Trust
for the period prior to such disposition) will nevertheless be required to
include in income as ordinary income accrued but unpaid interest on the Junior
Subordinated Debentures through the date of disposition and to add such amount
to its adjusted tax basis in its Capital Securities disposed of. Such holder
will recognize a capital loss on the disposition of its Capital Securities to
the extent the selling price (which may not fully reflect the value of accrued
but unpaid interest) is less than the holder's adjusted tax basis in the Capital
Securities (which will include accrued but unpaid interest). Subject to certain
limited exceptions, capital losses cannot be applied to offset ordinary income
for federal income tax purposes. Accrual basis holders will be subject to
similar treatment without regard to the Corporation's election to defer payments
of interest.
 
EXCHANGE OF CAPITAL SECURITIES
 
     The exchange of Capital Securities pursuant to the Exchange Offer should
not be treated as an "exchange" and, thus, should not be treated as a taxable
event for United States federal income tax purposes. If, however, the exchange
of the Capital Securities pursuant to the Exchange Offer were treated as an
exchange, such exchange should constitute a tax-free recapitalization for United
States federal income tax purposes. Accordingly, the Capital Securities received
should have the same issue price as the Capital Securities surrendered, and a
holder should have the same adjusted tax basis and holding period in the Capital
Securities received as the holder had in the Capital Securities surrendered.
 
BACKUP WITHHOLDING TAX AND INFORMATION REPORTING
 
     The amount of interest (and OID, if any) accrued on the Capital Securities
held of record by United States Persons (other than corporations and other
exempt holders) will be reported to the IRS. "Backup withholding" at a rate of
31% will apply to payments of interest to a non-exempt United States Person
unless the holder 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. Any amounts withheld from a holder under the backup
withholding rules will be allowed as a refund or a credit against such holder's
United States federal income tax liability, provided the required information is
furnished to the IRS.
 
     It is anticipated that income on the Capital Securities will be reported to
holders on IRS Form 1099 and mailed to holders of the Capital Securities by
January 31 following each calendar year.

PROPOSED TAX LEGISLATION
 
     On February 6, 1997, as part of President Clinton's Fiscal 1998 Budget
Proposal, the United States Treasury Department proposed legislation that would,
among other things, deny an issuer a deduction for United States federal income
tax purposes for the payment of interest on instruments with characteristics
similar to the Junior Subordinated Debentures. If the proposed legislation were
enacted in its current form, it is not expected to apply to the Junior
Subordinated Debentures by reason of the currently proposed prospective
effective date. There can be no assurances, however, that the proposed
legislation, if enacted, or similar legislation enacted after the date hereof
would not adversely affect the tax treatment of the Junior Subordinated
Debentures, resulting in a Tax Event, which may permit the Corporation, upon
approval of the Federal Reserve (if then required under applicable capital
guidelines or policies of the Federal Reserve) to cause a redemption of the
Trust Securities at the Special Event Redemption Price by electing to prepay the
Junior Subordinated Debentures at the Special Event Prepayment Price.
 
                              ERISA CONSIDERATIONS
 
     The Corporation, the obligor with respect to the New Junior Subordinated
Debentures held by the Trust, and its affiliates and the Property Trustee may
each be considered a "party in interest" (within the meaning of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")) or a "disqualified
person" (within the meaning of Section 4975 of the Code) with respect to many
employee benefit plans ("Plans") that are subject to ERISA and certain employee
benefit-related provisions of the Code. Any purchaser proposing to acquire New
Capital Securities with assets of any Plan should consult with its counsel. The
purchase and/or holding of New Capital Securities by a Plan that is subject to
the fiduciary responsibility provisions of ERISA or the prohibited transaction
provisions of Section 4975 of the Code (including individual retirement
arrangements and other plans described in Section 4975 (e)(1) of the Code) and
with respect to which the Corporation, the Property Trustee or any affiliate is
a service provider (or otherwise is a party in interest or a disqualified
person) may constitute or result in a prohibited transaction under ERISA or
Section 4975 of the Code, unless such New Capital Securities are acquired
pursuant to and in accordance with an applicable exemption, such as Prohibited
Transaction Class Exemption ("PTCE") 84-14 (an exemption for certain
transactions determined by an independent qualified professional asset manager),
PTCE 91-38 (an exemption for certain transactions involving bank collective
investment funds), PTCE 90-1 (an exemption for certain transactions involving
insurance company pooled separate accounts), PTCE 95-60 (an exemption for
transactions involving certain insurance company general accounts) or PTCE 96-23
(an exemption for certain transactions determined by an in-house asset manager).
In addition, as described below, a Plan fiduciary considering the acquisition of
New Capital Securities should be aware that the assets of the Trust may be
considered "plan assets" for ERISA purposes. Therefore, a Plan fiduciary should
consider whether the acquisition of Capital Securities could result in a
delegation of fiduciary authority to the Property Trustee, and, if so, whether
such a delegation of authority is permissible under the Plan's governing
instrument or any investment management agreement with the Plan. In making such
determination, a Plan fiduciary should note that the Property Trustee is a U.S.
bank qualified to be an investment manager (within the meaning of section 3(38)
of ERISA) to which such a delegation of authority generally would be permissible
under ERISA. Further, prior to an Event of Default with respect to the New
Junior Subordinated Debentures, the Property Trustee will have only limited
custodial and ministerial authority with respect to Trust assets.
 
     Under the U.S. Department of Labor regulations defining "plan assets" for
ERISA purposes (the "Plan Assets Regulations"), the assets of the Trust will be
considered plan assets of Plans owning New Capital Securities unless the
aggregate investment in New Capital Securities by "benefit plan investors" is
not deemed "significant" or the New Capital Securities qualify as "publicly
offered securities" as defined in such Regulations. For this purpose, equity
participation by benefit plan investors will not be considered "significant" on
any date only if, immediately after the most recent acquisition of Capital
Securities, the aggregate interest in the New Capital Securities held by benefit
plan investors will be less than 25% of the value of the New Capital Securities.
Although it is possible that the equity participation by benefit plan investors
in New Capital Securities on any date will not be "significant" for purposes of
the Plan Assets Regulations, such result cannot be assured.
 
                                       65
<PAGE>   67
 
     The New Capital Securities may qualify as "publicly offered securities"
under the Plan Assets Regulations if at the time of the Exchange Offer they are
also "widely held" and "freely transferable." Under the Regulations, a class of
securities is "widely held" only if it is a class of securities that is owned by
100 or more investors independent of the issuer and of one another. Although it
is possible that at the time of the Exchange Offer the New Capital Securities
will be "widely held," such result cannot be assured. Whether a security is
"freely transferable" for purposes of the Regulations is a factual question to
be determined on the basis of all relevant facts and circumstances. If at the
time of the Exchange Offer the New Capital Securities qualify as "publicly
offered securities," the assets of the Trust should not be "plan assets" with
respect to Plans acquiring New Capital Securities. If at the time of the
Exchange Offer the New Capital Securities do not qualify as "publicly offered
securities," the "plan asset" considerations discussed in the preceding
paragraphs could be applicable in connection with the investment by Plans in the
New Capital Securities.
 
                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives New Capital Securities for its own account
in connection with the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Capital Securities. This
Prospectus, as it may be amended or supplemented from time to time, may be used
by Participating Broker-Dealers during the period referred to below in
connection with resales of New Capital Securities received in exchange for Old
Capital Securities if such Old Capital Securities were acquired by such
Participating Broker-Dealers for their own accounts as a result of market-making
activities or other trading activities. The Corporation and the Trust have
agreed that this Prospectus, as it may be amended or supplemented from time to
time, may be used by a Participating Broker-Dealer in connection with resales of
such New Capital Securities for a period ending 90 days after the Expiration
Date (subject to extension under certain limited circumstances described herein)
or, if earlier, when all such New Capital Securities have been disposed of by
such Participating Broker-Dealer. However, a Participating Broker-Dealer who
intends to use this Prospectus in connection with the resale of New Capital
Securities received in exchange for Old Capital Securities pursuant to the
Exchange Offer must notify the Corporation or the Trust, or cause the
Corporation or the Trust to be notified, on or prior to the Expiration Date,
that it is a Participating Broker-Dealer. Such notice may be given in the space
provided for that purpose in the Letter of Transmittal or may be delivered to
the Exchange Agent at one of the addresses set forth herein under "The Exchange
Offer -- Exchange Agent." See "The Exchange Offer -- Resales of New Capital
Securities."
 
     The Corporation or the Trust will not receive any cash proceeds from the
issuance of the New Capital Securities offered hereby. New Capital Securities
received by broker-dealers for their own accounts in connection with the
Exchange Offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the New Capital Securities or a combination of such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or at negotiated prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such New Capital Securities.
 
     Any broker-dealer that resells New Capital Securities that were received by
it for its own account in connection with the Exchange Offer and any broker or
dealer that participates in a distribution of such New Capital Securities may be
deemed to be an "underwriter" within the meaning of the Securities Act, and any
profit on any such resale of New Capital Securities and any commissions or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.
 
                                 LEGAL MATTERS
 
     Certain legal matters will be passed upon for the Corporation and the Trust
by Skadden, Arps, Slate, Meagher & Flom (Illinois), Chicago, Illinois, relying
as to all matters of Nevada law upon Marshall Hill Cassas & de Lipkau, Reno,

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Corporation has purchased for the benefit of its officers and
directors, and those of certain subsidiaries, insurance policies whereby the
insurance companies agree, among other things, that in the event any such
officer or director becomes legally obligated to make a payment (including legal
fees and expenses) in connection with an alleged wrongful act, such insurance
companies will pay the Corporation up to $5,000,000. Wrongful act means any
breach of duty, neglect, error, misstatement, misleading statement or other act
done by an officer or director of the Corporation or any subsidiary.
 
     The Corporation is required, pursuant to AMCORE's Restated Articles of
Incorporation (the "AMCORE Charter"), to indemnify all persons who may be
indemnified under Nevada law to the fullest extent permitted by such law.
Generally, under Nevada law, a corporation may indemnify officers, directors,
employees and agents of a corporation against all expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by them in connection with any threatened, pending or completed civil,
criminal, administrative or investigative proceeding (other than derivative
actions) if they acted in good faith and in a manner they reasonably believed to
be in or not opposed to the best interests of the corporation and, with respect
to any criminal action, they had no reasonable cause to believe their conduct
was unlawful. With respect to derivative actions, officers, directors, employees
and agents of a corporation may be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by them in connection with the
defense or settlement of such action if they acted in good faith and in a manner
they reasonably believed to be in or not opposed to the best interests of the
corporation, except that no such indemnification may be made in respect of any
claim as to which such person shall have been adjudged to be liable to the
corporation, unless and only to the extent that the court in which the action
was brought determines that such person is entitled to indemnification despite
the adjudication of liability. To the extent that an officer, director, employee
or agent is successful on the merits or otherwise in defense of any action, suit
or proceeding referred to above, the corporation shall indemnify such officer,
director, employee or agent against expenses (including attorneys' fees)
actually and reasonably incurred in connection therewith.
 
     The AMCORE Charter also permits the Corporation to purchase and maintain
insurance or make other financial arrangements to insure its directors,
officers, employees and agents against liabilities, whether or not AMCORE is
itself permitted to indemnify against such liabilities.
 
     As permitted by Nevada law, the AMCORE Charter eliminates, to the fullest
extent permitted by Nevada law, the personal liability of directors and officers
to the Corporation for breaches of fiduciary duty. Under the AMCORE Charter,
directors and officers are not indemnified for acts or omissions involving
intentional misconduct, fraud or a knowing violation of law or for violations of
Section 78.300 of the Nevada General Corporation Law regarding unlawful payment
of dividends.
 
     The Corporation has entered into indemnification contracts (the
"Indemnification Agreements") with its directors and officers. The
Indemnification Agreements provide for indemnification of directors and officers
to the fullest extent permitted by law. These agreements cover all expenses,
judgments, fines and penalties incurred and amounts paid in settlement in
connection with investigating, defending, being a witness or participating in or
preparing to defend, be a witness in or participate in any threatened, pending
or completed action, suit or proceeding or any inquiry or investigation, whether
civil, criminal, administrative or otherwise, related to the fact that such
director or officer was a director or officer, employee, agent or fiduciary of
AMCORE or was serving as such at the request of the Corporation. The
Indemnification Agreements impose upon the Corporation the burden of proving
that the director or officer is not entitled to indemnification.
 
     Insofar as the foregoing provisions may permit indemnification of
directors, officers or persons controlling the Corporation for liabilities
arising under the Securities Act, the Corporation understands that in the
opinion of the Commission such indemnification is against public policy as
expressed in the Securities Act and therefore is unenforceable.

ITEM 22. UNDERTAKINGS
 
     Each of the undersigned Registrants hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, as amended, each
filing of a Registrant's annual report pursuant to Section 13(a) or Section
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing
of an employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of each
undersigned Registrant pursuant to the provisions, or
 
                                      II-2

otherwise, each Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
each undersigned Registrant of expenses incurred or paid by a director, officer
of controlling person of each Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, each Registrant will,
unless in the opinion of its counsel the matter has been settled by the
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
     The undersigned Registrants hereby undertake to respond to requests for
information that is incorporated by reference into the Prospectus pursuant to
Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.
 
     The undersigned Registrants hereby undertake to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired or involved therein, that was not the subject of and
included in the registration statement when it became effective.

any increase or decrease in the amount of outstanding Securities represented
thereby shall be made by the Trustee, in accordance with instructions given by
the Company as required by this Section 2.05.

                 (c)      The Global Securities may be transferred, in whole
but not in part, only to the Depositary, another nominee of the Depositary, or
to a successor Depositary selected or approved by the Company or to a nominee
of such successor Depositary.

                 (d)      If at any time the Depositary notifies the Company
that it is unwilling or unable to continue as Depositary or the Depositary has
ceased to be a clearing agency registered under the Exchange Act, and a
successor Depositary is not appointed by the Company within 90 days after the
Company receives such notice or becomes aware of such condition, as the case
may be, the Company will execute, and the Trustee, upon written notice from the
Company, will authenticate and make available for delivery the Definitive
Securities, in authorized denominations, and in an aggregate principal amount
equal to the principal amount of the Global Security in exchange for such
Global Security.  If there is an Event of Default, the Depositary shall have
the right to exchange the Global Securities for Definitive Securities.  In
addition, the Company may at any time determine that the Securities shall no
longer be represented by a Global Security.  In the event of such an Event of
Default or such a determination, the Company shall execute, and subject to
Section 2.07, the Trustee, upon receipt of an Officers' Certificate evidencing
such determination by the Company, will authenticate and make available for
delivery the Definitive Securities, in authorized denominations, and in an
aggregate principal amount equal to the principal amount of the Global Security
in exchange for such Global Security.  Upon the exchange of the Global Security
for such Definitive Securities, in authorized denominations, the Global
Security shall be cancelled by the Trustee.  Such Definitive Securities issued
in exchange for the Global Security shall be registered in such names and in
such authorized denominations





                                       15
<PAGE>   24

as the Depositary, pursuant to instructions from its direct or indirect
participants or otherwise, shall instruct the Trustee.  The Trustee shall
deliver such Definitive Securities to the Depositary for delivery to the
Persons in whose names such Definitive Securities are so registered.

                 SECTION 2.06     Interest.

                 (a)      Each Security will bear interest at the rate of
9.35% per annum (the "Coupon Rate") from the most recent date to which interest
has been paid or duly provided for or, if no interest has been paid or duly
provided for, from the Issue Date, until the principal thereof becomes due and
payable, and at the Coupon Rate on any overdue principal (and premium, if any)
and (to the extent that payment of such interest is enforceable under
applicable law) on any overdue installment of interest, compounded
semi-annually, payable (subject to the provisions of Article XVI) semi-annually
in arrears on June 15 and December 15 of each year (each, an "Interest Payment
Date") commencing on June 15, 1997, to the Person in whose name such Security
or any predecessor Security is registered, at the close of business on the
regular record date for such interest installment, which shall be the 15th day
of the month immediately preceding the month in which the relevant Interest
Payment Date falls.

                 (b)      Interest will be computed on the basis of a 360-day
year consisting of twelve 30-day months and, for any period of less than a full
calendar month, the number of days lapsed in such month.  In the event that any
Interest Payment Date falls on a day that is not a Business Day, then payment
of interest payable on such date will be made on the next succeeding day which
is a Business Day (and without any interest or other payment in respect of any
such delay), except that if such next succeeding Business Day falls in the next
succeeding calendar year, then such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date.

                 (c)      During such time as the Property Trustee is the
holder of any Securities, the Company shall pay any additional amounts on the
Securities as may be necessary in order that the amount of Distributions then
due and payable by the AMCORE Capital Trust on the outstanding Securities shall
not be reduced as a result of any additional taxes, duties and other
governmental charges to which the AMCORE Capital Trust has become subject as a
result of a Tax Event ("Additional Sums").

                 SECTION 2.07     Transfer and Exchange.

                 (a)  Transfer Restrictions.  The Series A Securities, and
those Series B Securities with respect to which any Person described in Section
2.04(b)(A), (B) or (C) is the beneficial





                                       16
<PAGE>   25

owner, may not be transferred except in compliance with the legend contained in
Exhibit A unless otherwise determined by the Company in accordance with
applicable law.  Upon any distribution of the Securities following a
Dissolution Event, the Company and the Trustee shall enter into a supplemental
indenture pursuant to Section 9.01 to provide for the transfer restrictions and
procedures with respect to the Securities substantially similar to those
contained in the Declaration to the extent applicable in the circumstances
existing at such time.


                 (b)  General Provisions Relating to Transfers and Exchanges.
To permit registrations of transfers and exchanges, upon surrender for
registration of transfer of any Security at the office or agency of the Company
maintained for the purpose pursuant to Section 3.02, the Company shall execute,
and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of the same series, of
any authorized denominations and of a like aggregate principal amount.

                 At the option of the holder, Securities of any series may be
exchanged for other Securities of the same series, of any authorized
denominations and of a like aggregate principal amount, upon surrender of the
Securities to be exchanged at such office or agency.  Whenever any Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Securities which the holder making the
exchange is entitled to receive.

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

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

                 No service charge shall be made to a holder for any
registration of transfer or exchange, but the Company may require payment of a
sum sufficient to cover any transfer tax or similar governmental charge payable
in connection therewith.

                 The Company shall not be required to (i) issue, register the
transfer of or exchange Securities during a period





                                       17
<PAGE>   26

beginning at the opening of business 15 days before the day of mailing of a
notice of redemption or any notice of selection of Securities for redemption
under Article XIV hereof and ending at the close of business on the day of such
mailing; or (ii) register the transfer of or exchange any Security so selected
for redemption in whole or in part, except the unredeemed portion of any
Security being redeemed in part.

                 (c)  Exchange of Series A Securities for Series B Securities.
The Series A Securities may be exchanged for Series B Securities pursuant to
the terms of the Exchange Offer.  The Trustee shall make the exchange as
follows:

                 The Company shall present the Trustee with an Officers'
Certificate certifying the following:

                 (A)      upon issuance of the Series B Securities, the
                          transactions contemplated by the Exchange Offer have
                          been consummated; and

                 (B)      the principal amount of Series A Securities properly
                          tendered in the Exchange Offer that are represented
                          by a Global Security and the principal amount of
                          Series A Securities properly tendered in the Exchange
                          Offer that are represented by Definitive Securities,
                          the name of each holder of such Definitive
                          Securities, the principal amount properly tendered in
                          the Exchange Offer by each such holder and the name
                          and address to which Definitive Securities for Series
                          B Securities shall be registered and sent for each
                          such holder.

                 The Trustee, upon receipt of (i) such Officers' Certificate,
(ii) an Opinion of Counsel (x) to the effect that the Series B Securities have
been registered under Section 5 of the Securities Act and the Indenture has
been qualified under the Trust Indenture Act and (y) with respect to the
matters set forth in Section 3(p) of the Registration Rights Agreement and
(iii) a Company Order, shall authenticate (A) a Global Security representing
Series B Securities in aggregate principal amount equal to the aggregate
principal amount of Series A Securities represented by a Global Security
indicated in such Officers' Certificate as having been properly tendered and
(B) Definitive Securi- ties representing Series B Securities registered in the
names of, and in the principal amounts indicated in, such Officers'
Certificate.

                 If the principal amount of the Global Security for the Series
B Securities is less than the principal amount of the Global Security for the
Series A Securities, the Trustee shall make an endorsement on such Global
Security for Series A Securi-





                                       18
<PAGE>   27

ties indicating a reduction in the principal amount represented thereby.

                 The Trustee shall deliver such Definitive Securities
representing Series B Securities to the holders thereof as indicated in such
Officers' Certificate.

                 SECTION 2.08     Replacement Securities.

                 If any mutilated Security is surrendered to the Trustee, or
the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, the Company shall issue and the
Trustee shall authenticate a replacement Security if the Trustee's requirements
for replacements of Securities are met.  An indemnity bond must be supplied by
the holder that is sufficient in the judgment of the Trustee and the Company to
protect the Company, the Trustee, any agent thereof or any authenticating agent
from any loss that any of them may suffer if a Security is replaced.  The
Company or the Trustee may charge for its expenses in replacing a Security.

                 Every replacement Security is an obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Securities duly issued hereunder.

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

                 SECTION 2.09     Temporary Securities.

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

                 If temporary Securities are issued, the Company shall cause
definitive Securities to be prepared without unreasonable delay.  The
definitive Securities shall be printed, lithographed or engraved, or provided
by any combination thereof, or in any other manner permitted by the rules and
regulations of any applicable securities exchange, all as determined by the
officers executing such definitive Securities.  After the preparation of
definitive Securities, the temporary Securities shall be ex-





                                       19
<PAGE>   28

changeable for definitive Securities upon surrender of the temporary Securities
at the office or agency maintained by the Company for such purpose pursuant to
Section 3.02 hereof, without charge to the Securityholder.  Upon surrender for
cancellation of any one or more temporary Securities, the Company shall
execute, and the Trustee shall authenticate and make available for delivery, in
exchange therefor the same aggregate principal amount of definitive Securities
of authorized denominations.  Until so exchanged, the temporary Securities
shall in all respects be entitled to the same benefits under this Indenture as
definitive Securities.

                 SECTION 2.10     Cancellation.

                 The Company at any time may deliver Securities to the Trustee
for cancellation.  The Trustee and no one else shall cancel all Securities
surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall retain or destroy cancelled Securities in accordance
with its normal practices (subject to the record retention requirement of the
Exchange Act) unless the Company directs them to be returned to it.  The
Company may not issue new Securities to replace Securities that have been
redeemed or paid or that have been delivered to the Trustee for cancellation.

                 SECTION 2.11     [INTENTIONALLY OMITTED]

                 SECTION 2.12     Defaulted Interest.

                 Any interest on any Security that is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the holder
on the relevant regular record date by virtue of having been such holder; and
such Defaulted Interest shall be paid by the Company, at its election, as
provided in clause (a) or clause (b) below:

                 (a)  The Company may make payment of any Defaulted Interest on
         Securities to the Persons in whose names such Securities (or their
         respective Predecessor Securities) are registered at the close of
         business on a special record date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner: the Company
         shall notify the Trustee in writing of the amount of Defaulted
         Interest proposed to be paid on each such Security and the date of the
         proposed payment, and at the same time the Company shall deposit with
         the Trustee an amount of money equal to the aggregate amount proposed
         to be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit prior to the
         date of the proposed payment, such money when deposited to be held in
         trust for the benefit of the Persons entitled to such De-





                                       20
<PAGE>   29

         faulted Interest as in this clause provided.  Thereupon the Trustee
         shall fix a special record date for the payment of such Defaulted
         Interest which shall not be more than 15 nor less than 10 days prior to
         the date of the proposed payment and not less than 10 days after the
         receipt by the Trustee of the notice of the proposed payment.  The
         Trustee shall promptly notify the Company of such special record date
         and, in the name and at the expense of the Company, shall cause notice
         of the proposed payment of such Defaulted Interest and the special
         record date therefor to be mailed, first class postage prepaid, to each
         Securityholder at his or her address as it appears in the Security
         Register, not less than 10 days prior to such special record date.
         Notice of the proposed payment of such Defaulted Interest and the
         special record date therefor having been mailed as aforesaid, such
         Defaulted Interest shall be paid to the Persons in whose names such
         Securities (or their respective Predecessor Securities) are registered
         on such special record date and shall be no longer payable pursuant to
         the following clause (b).

                 (b)  The Company may make payment of any Defaulted Interest on
         any Securities in any other lawful manner not inconsistent with the
         requirements of any securities exchange on which such Securities may
         be listed, and upon such notice as may be required by such exchange,
         if, after notice given by the Company to the Trustee of the proposed
         payment pursuant to this clause, such manner of payment shall be
         deemed practicable by the Trustee.

                 SECTION 2.13     CUSIP Numbers.

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

                                  ARTICLE III

                      PARTICULAR COVENANTS OF THE COMPANY

                 SECTION 3.01     Payment of Principal, Premium and Interest.

                 The Company covenants and agrees for the benefit of the
holders of the Securities that it will duly and punctually pay or cause to be
paid the principal of and premium, if any, and interest on the Securities at
the place, at the respective times and in the manner provided herein.  Except
as provided in Section 2.03, each installment of interest on the Securities may
be paid by mailing checks for such interest payable to the order of the holder
of Security entitled thereto as they appear in the Security Register.  The
Company further covenants to pay any and all amounts, including, without
limitation, Additional Sums, as may be required pursuant to Section 2.06(c),
Liquidated Damages, if any, on the dates and in the manner required under the
Registration Rights Agreement, and Compounded Interest, as may be required
pursuant to Section 16.01.

                 SECTION 3.02     Offices for Notices and Payments, etc.

                 So long as any of the Securities remain outstanding, the
Company will maintain in the Borough of Manhattan, The City of New York, an
office or agency where the Securities may be presented for payment, an office
or agency where the Securities may be presented for registration of transfer
and for exchange as in this Indenture provided and an office or agency where
notices and demands to or upon the Company in respect of the Securities or of
this Indenture may be served.  The Company will give to the Trustee written
notice of the location of any such office or agency and of any change of
location thereof.  Until otherwise designated from time to time by the Company
in a notice to the Trustee, any such office or agency for all of the above
purposes shall be the Principal Office of the Trustee.  In case the Company
shall fail to maintain any such office or agency in the Borough of Manhattan,
The City of New York, or shall fail to give such notice of the location or of
any change in the location thereof, presentations and demands may be made and
notices may be served at the New York office of the Trustee.

                 In addition to any such office or agency, the Company may from
time to time designate one or more offices or agencies outside the Borough of
Manhattan, The City of New York, where the Securities may be presented for
payment, registration of transfer and for exchange in the manner provided in
this Indenture, and the Company may from time to time rescind such designation,
as the Company may deem desirable or expedient; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain any such office





                                       22
<PAGE>   31

or agency in the Borough of Manhattan, The City of New York, for the purposes
above mentioned.  The Company will give to the Trustee prompt written notice of
any such designation or rescission thereof.

                 SECTION 3.03     Appointments to Fill Vacancies in Trustee's
                                  Office.

                 The Company, whenever necessary to avoid or fill a vacancy in
the office of Trustee, will appoint, in the manner provided in Section 6.10, a
Trustee, so that there shall at all times be a Trustee hereunder.

                 SECTION 3.04     Provision as to Paying Agent.

                 (a)      If the Company shall appoint a paying agent other
                          than the Trustee with respect to the Securities, it
                          will cause such paying agent to execute and deliver
                          to the Trustee an instrument in which such agent
                          shall agree with the Trustee, subject to the
                          provision of this Section 3.04,

                          (1)     that it will hold all sums held by it as such
                                  agent for the payment of the principal of and
                                  premium, if any, or interest on the
                                  Securities (whether such sums have been paid
                                  to it by the Company or by any other obligor
                                  on the Securities) in trust for the benefit
                                  of the holders of the Securities;

                          (2)     that it will give the Trustee notice of any
                                  failure by the Company (or by any other
                                  obligor on the Securities) to make any
                                  payment of the principal of and premium or
                                  interest (including Additional Sums and
                                  Compounded Interest, if any) and Liquidated
                                  Damages, if any, on the Securities when the
                                  same shall be due and payable; and

                          (3)     that it will at any time during the
                                  continuance of any such failure, upon the
                                  written request of the Trustee, forthwith pay
                                  to the Trustee all sums so held in trust by
                                  it as such paying agent.

                 (b)      If the Company shall act as its own paying agent, it
                          will, on or before each due date of the principal of
                          and premium, if any, or interest on the Securities,
                          set aside, segregate and hold in trust for the
                          benefit of the holders of the Securities a sum
                          sufficient to pay such principal, premium or interest
                          so becoming due and will notify the





                                       23

                          Trustee of any failure to take such action and of any
                          failure by the Company (or by any other obligor under
                          the Securities) to make any payment of the principal
                          of and premium, if any, or interest on the Securities
                          when the same shall become due and payable.

                 (c)      Anything in this Section 3.04 to the contrary
                          notwithstanding, the Company may, at any time, for
                          the purpose of obtaining a satisfaction and discharge

                          mailed, a written statement to the effect that, in the
                          opinion of the Trustee, such mailing would be contrary
                          to the best interests of the holders of Securities of
                          such series or all Securities, as the case may be, or
                          would be in violation of applicable law.  Such written
                          statement shall specify the basis of such opinion.  If
                          the Commission, after opportunity for a hearing upon
                          the objections specified in the written statement so
                          filed, shall enter an order refusing to sustain any of
                          such objections or if, after the entry of an order
                          sustaining one or more of such objections, the
                          Commission shall find, after notice and opportunity
                          for hearing, that all the objections so sustained have
                          been met and shall enter an order so declaring, the
                          Trustee shall mail copies of such material to all such
                          Securityholders with reasonable promptness after the
                          entry of such order and the renewal of such tender;
                          otherwise the Trustee shall be relieved of any
                          obligation or duty to such applicants respecting their
                          application.

                          holding the same, agrees with the Company and the

                          any paying agent shall be held accountable by reason
                          of the disclosure of any such information as to the
                          names and addresses of the holders of Securities in
                          accordance with the provisions of subsection (b) of

                          which such information was derived, and that the
                          Trustee shall not be held accountable by reason of
                          mailing any material pursuant to a request made under
                          said subsection (b).

                          is entitled to rely exclusively on Officers'
                          Certificates).

                 (e)      So long as is required for an offer or sale of the

                          clause (d)(4) thereunder to each Securityholder and

                          of Restricted Securities, unless such information is
                          furnished to the Commission pursuant to Section 13 or
                          15(d) of the Exchange Act.

                 SECTION 4.04     Reports by the Trustee.

                 (a)      The Trustee shall transmit to Securityholders such
                          reports concerning the Trustee and its actions under
                          this Indenture as may be required pursuant to the
                          Trust Indenture Act at the times and in the manner
                          provided pursuant thereto.  If required by Section
                          313(a) of the Trust Indenture Act, the Trustee shall,
                          within sixty days after each November 15 following
                          the date of this Indenture, commencing November 15,
                          1997, deliver to Securityholders a brief report,
                          dated as of such November 15, which complies with the
                          provisions of such Section 313(a).

                 (b)      A copy of each such report shall, at the time of such
                          transmission to Securityholders, be filed by the

                          the Securities are listed, with the Commission and
                          with the Company.  The Company will promptly notify
                          the Trustee when the Securities are listed on any
                          stock exchange.

                  REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS
                              ON EVENT OF DEFAULT

                 SECTION 5.01     Events of Default.

                 One or more of the following events of default shall
constitute an Event of Default hereunder (whatever the reason for such Event of
Default and whether it shall be voluntary 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):

                 (a)      default in the payment of any interest upon any
                          Security or any Other Debentures when it becomes due
                          and payable, and continuance of such default for a
                          period of 30 days; provided, however, that a valid
                          extension of an interest payment period by the Company
                          in accordance with the terms hereof shall not
                          constitute a default in the payment of interest for
                          this purpose; or

                 (b)      default in the payment of all or any part of the
                          principal of (or premium, if any, on) any Security or
                          any Other Debentures as and when the same shall
                          become due and payable either at maturity, upon
                          redemption, by declaration of acceleration of
                          maturity or otherwise; or

                 (c)      default in the performance, or breach, of any
                          covenant or warranty of the Company in this Indenture
                          (other than a covenant or warranty a default in whose
                          performance or whose breach is elsewhere in this
                          Section specifically dealt with), and continuance of
                          such default or breach for a period of 90 days after
                          there has been given, by registered or certified
                          mail, to the Company by the Trustee or to the Company
                          and the Trustee by the holders of at least 25% in
                          aggregate principal amount of the outstanding
                          Securities a written notice specifying such default
                          or breach and re- quiring it to be remedied and
                          stating that such notice is a "Notice of Default"
                          hereunder; or

                 (d)      a court having jurisdiction in the premises shall
                          enter a decree or order for relief in respect of the
                          Company in an involuntary case under any applicable
                          bankruptcy, insolvency or other similar law now or
                          hereafter in effect, or appointing a receiver,
                          liquidator, assignee, custodian, trustee,
                          sequestrator (or similar official) of the Company or
                          for any substantial part of its property, or ordering
                          the winding-up or liquidation of its affairs and such
                          decree or order shall remain unstayed and in effect
                          for a period of 90 consecutive days; or

                 (e)      the Company shall commence a voluntary case under any
                          applicable bankruptcy, insolvency or other similar
                          law now or hereafter in effect, shall consent to the
                          entry of an order for relief in an involuntary case
                          under any such law, or shall consent to the
                          appointment of or taking possession by a receiver,
                          liquidator, assignee, trustee, custodian,
                          sequestrator (or other similar official) of the
                          Company or of any substantial part of its property,
                          or shall make any general assignment for the benefit
                          of creditors, or shall fail generally to pay its
                          debts as they become due.

                 If an Event of Default with respect to Securities at the time
outstanding occurs and is continuing, then in every such case the Trustee or
the holders of not less than 25% in aggregate principal amount of the
Securities then outstanding may declare





                                       32
<PAGE>   41

the principal amount of all Securities to be due and payable immediately, by a
notice in writing to the Company (and to the Trustee if given by the holders of
the outstanding Securities), and upon any such declaration the same shall
become immediately due and payable.

                 The foregoing provisions, however, are subject to the
condition that if, at any time after the principal of the Securities shall have
been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, (i) the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay (A) all matured installments of interest upon all the
Securities and the principal of and premium, if any, on any and all Securities
which shall have become due otherwise than by acceleration (with interest upon
such principal and premium, if any, and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest, at the same rate as the rate of interest specified in the Securities
to the date of such payment or deposit) and (B) such amount as shall be
sufficient to cover reasonable compensation to the Trustee and each predecessor
Trustee, their respective agents, attorneys and counsel, and all other amounts
due to the Trustee pursuant to Section 6.06, and (ii) any and all Events of
Default under the Indenture, other than the non-payment of the principal of the
Securities which shall have become due solely by such declaration of
acceleration, shall have been cured, waived or otherwise remedied as provided
herein, then, in every such case, the holders of a majority in aggregate
principal amount of the Securities then outstanding, by written notice to the
Company and to the Trustee, may rescind and annul such declaration and its
consequences, but no such waiver or rescission and annulment shall extend to or
shall affect any subsequent default or shall impair any right consequent
thereon.

                 In case the Trustee shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or
abandoned because of such rescission or annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such
case the Company, the Trustee and the holders of the Securities shall be
restored respectively to their several positions and rights hereunder, and all
rights, remedies and powers of the Company, the Trustee and the holders of the
Securities shall continue as though no such proceeding had been taken.

                 SECTION 5.02     Payment of Securities on Default; Suit
                                  Therefor.

                 The Company covenants that (a) in case default shall be made
in the payment of any installment of interest upon any of the Securities as and
when the same shall become due and payable,





                                       33
<PAGE>   42

and such default shall have continued for a period of 30 days, or (b) in case
default shall be made in the payment of the principal of or premium, if any, on
any of the Securities as and when the same shall have become due and payable,
whether at maturity of the Securities or upon redemption or by declaration or
otherwise, then, upon demand of the Trustee, the Company will pay to the
Trustee, for the benefit of the holders of the Securities, the whole amount
that then shall have become due and payable on all such Securities for
principal and premium, if any, or interest, or both, as the case may be, with
interest upon the overdue principal and premium, if any, and (to the extent
that payment of such interest is enforceable under applicable law and, if the
Securities are held by AMCORE Capital Trust or a trustee of such trust, without
duplication of any other amounts paid by AMCORE Capital Trust or a trustee in
respect thereof) upon the overdue installments of interest at the rate borne by
the Securities; and, in addition thereto, such further amount as shall be
sufficient to cover the costs and expenses of collection, including a
reasonable compensation to the Trustee, its agents, attorneys and counsel, and
all other amounts due to the Trustee pursuant to Section 6.06.

                 In case the Company shall fail forthwith to pay such amounts
upon such demand, the Trustee, in its own name and as trustee of an express
trust, shall be entitled and empowered to institute any actions or proceedings
at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may
enforce any such judgment or final decree against the Company or any other
obligor on the Securities and collect in the manner provided by law out of the
property of the Company or any other obligor on the Securities wherever
situated the moneys adjudged or decreed to be payable.

                 In case there shall be pending proceedings for the bankruptcy
or for the reorganization of the Company or any other obligor on the Securities
under Title 11, United States Code, or any other applicable law, or in case a
receiver or trustee shall have been appointed for the property of the Company
or such other obligor, or in the case of any other similar judicial proceedings
relative to the Company or other obligor upon the Securities, or to the
creditors or property of the Company or such other obligor, the Trustee,
irrespective of whether the principal of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand pursuant to the provisions of
this Section 5.02, shall be entitled and empowered, by intervention in such
proceedings or otherwise, to file and prove a claim or claims for the whole
amount of principal and interest owing and unpaid in respect of the Securities
and, in case of any judicial proceedings, to file such proofs of claim and
other papers or documents as may be necessary or advisable in order to





                                       34
<PAGE>   43

have the claims of the Trustee (including any claim for amounts due to the
Trustee pursuant to Section 6.06) and of the Securityholders allowed in such
judicial proceedings relative to the Company or any other obligor on the
Securities, or to the creditors or property of the Company or such other
obligor, unless prohibited by applicable law and regulations, to vote on behalf
of the holders of the Securities in any election of a trustee or a standby
trustee in arrangement, reorganization, liquidation or other bankruptcy or
insolvency proceedings or person performing similar functions in comparable
proceedings, and to collect and receive any moneys or other property payable or
deliverable on any such claims, and to distribute the same after the deduction
of its charges and expenses; and any receiver, assignee or trustee in
bankruptcy or reorganization is hereby authorized by each of the
Securityholders to make such payments to the Trustee, and, in the event that
the Trustee shall consent to the making of such payments directly to the
Securityholders, to pay to the Trustee such amounts as shall be sufficient to
cover reasonable compensation to the Trustee, each predecessor Trustee and
their respective agents, attorneys and counsel, and all other amounts due to
the Trustee pursuant to Section 6.06.

                 Nothing herein contained shall be construed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any holder thereof or to
authorize the Trustee to vote in respect of the claim of any Securityholder in
any such proceeding.

                 All rights of action and of asserting claims under this
Indenture, or under any of the Securities, may be enforced by the Trustee
without the possession of any of the Securities, or the production thereof on
any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment shall be for the ratable benefit of
the holders of the Securities.

                 In any proceedings brought by the Trustee (and also any
proceedings involving the interpretation of any provision of this Indenture to
which the Trustee shall be a party) the Trustee shall be held to represent all
the holders of the Securities, and it shall not be necessary to make any
holders of the Securities parties to any such proceedings.

                 SECTION 5.03     Application of Moneys Collected by Trustee.

                 Any moneys collected by the Trustee shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such moneys, upon presentation of the





                                       35
<PAGE>   44

Securities in respect of which moneys have been collected, and stamping thereon
the payment, if only partially paid, and upon surrender thereof if fully paid:

                 First:  To the payment of costs and expenses of collection
applicable to the Securities and all amounts due to the Trustee pursuant to
Section 6.06;

                 Second:  To the payment of all Senior Indebtedness of the
Company if and to the extent required by Article XV;

                 Third:  To the payment of the amounts then due and unpaid upon
Securities for principal of (and premium, if any) and interest on the
Securities, in respect of which or for the benefit of which money has been
collected, ratably, without preference of priority of any kind, according to
the amounts due on such Securities for principal (and premium, if any) and
interest, respectively; and

                 Fourth:  To the Company.

                 SECTION 5.04     Proceedings by Securityholders.

                 No holder of any Security shall have any right by virtue of or
by availing of any provision of this Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this Indenture
or for the appointment of a receiver or trustee, or for any other remedy
hereunder, unless such holder previously shall have given to the Trustee
written notice of an Event of Default and of the continuance thereof with
respect to the Securities specifying such Event of Default, as hereinbefore
provided, and unless also the holders of not less than 25% in aggregate
principal amount of the Securities then outstanding shall have made written
request upon the Trustee to institute such action, suit or proceeding in its
own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Trustee for 60 days
after its receipt of such notice, request and offer of indemnity shall have
failed to institute any such action, suit or proceeding, it being understood
and intended, and being expressly covenanted by the taker and holder of every
Security with every other taker and holder and the Trustee, that no one or more
holders of Securities shall have any right in any manner whatever by virtue of
or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other holder of Securities, or to obtain or seek to
obtain priority over or preference to any other such holder, or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all holders of Securities.





                                       36
<PAGE>   45

                 Notwithstanding any other provisions in this Indenture,
however, the right of any holder of any Security to receive payment of the
principal of (premium, if any) and interest on such Security, on or after the
same shall have become due and payable, or to institute suit for the
enforcement of any such payment, shall not be impaired or affected without the
consent of such holder and by accepting a Security hereunder it is expressly
understood, intended and covenanted by the taker and holder of every Security
with every other such taker and holder and the Trustee, that no one or more
holders of Securities shall have any right in any manner whatsoever by virtue
or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of the holders of any other Securities, or to obtain or
seek to obtain priority over or preference to any other such holder, or to
enforce any right under this Indenture, except in the manner herein provided
and for the equal, ratable and common benefit of all holders of Securities.
For the protection and enforcement of the provisions of this Section, each and
every Securityholder and the Trustee shall be entitled to such relief as can be
given either at law or in equity.

                 The Company and the Trustee acknowledge that pursuant to the
Declaration, the holders of Capital Securities are entitled, in the
circumstances and subject to the limitations set forth therein, to commence a
Direct Action with respect to any Event of Default under this Indenture and the
Securities.

                 SECTION 5.05     Proceedings by Trustee.

                 In case an Event of Default occurs with respect to Securities
and is continuing, the Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
of such rights, either by suit in equity or by action at law or by proceeding
in bankruptcy or otherwise, whether for the specific enforcement of any
covenant or agreement contained in this Indenture or in aid of the exercise of
any power granted in this Indenture, or to enforce any other legal or equitable
right vested in the Trustee by this Indenture or by law.

                 SECTION 5.06     Remedies Cumulative and Continuing.

                 Except as provided in the last paragraph of Section 2.08, all
powers and remedies given by this Article V to the Trustee or to the
Securityholders shall, to the extent permitted by law, be deemed cumulative and
not exclusive of any other powers and remedies available to the Trustee or the
holders of the Securities, by judicial proceedings or otherwise, to enforce the
performance or observance of the covenants and agreements contained in this
Indenture or otherwise established with respect to the Securities, and no delay
or omission of the Trustee or of





                                       37
<PAGE>   46

any holder of any of the Securities to exercise any right or power accruing
upon any Event of Default occurring and continuing as aforesaid shall impair
any such right or power, or shall be construed to be a waiver of any such
default or an acquiescence therein; and, subject to the provisions of Section
5.04, every power and remedy given by this Article V or by law to the Trustee
or to the Securityholders may be exercised from time to time, and as often as
shall be deemed expedient, by the Trustee or by the Securityholders.

                 SECTION 5.07     Direction of Proceedings and Waiver of
                                  Defaults by Majority of Securityholders.

                 The holders of a majority in aggregate principal amount of the
Securities at the time outstanding shall have the right to direct the time,
method, and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee; provided,
however, that (subject to the provisions of Section 6.01) the Trustee shall
have the right to decline to follow any such direction if the Trustee shall
determine that the action so directed would be unjustly prejudicial to the
holders not taking part in such direction or if the Trustee being advised by
counsel determines that the action or proceeding so directed may not lawfully
be taken or if the Trustee in good faith by its board of directors or trustees,
executive committee, or a trust committee of directors or trustees and/or
Responsible Officers shall determine that the action or proceedings so directed
would involve the Trustee in personal liability.  Prior to any declaration
accelerating the maturity of the Securities, the holders of a majority in
aggregate principal amount of the Securities at the time outstanding may on
behalf of the holders of all of the Securities waive any past default or Event
of Default and its consequences except a default (a) in the payment of
principal of or premium, if any, or interest on any of the Securities or (b) in
respect of covenants or provisions hereof which cannot be modified or amended
without the consent of the holder of each Security affected; provided, however,
that if the Securities are held by the Property Trustee, such waiver or
modification to such waiver shall not be effective until the holders of a
majority in aggregate liquidation amount of Trust Securities shall have
consented to such waiver or modification to such waiver; provided further, that
if the consent of the holder of each outstanding Security is required, such
waiver shall not be effective until each holder of the Trust Securities shall
have consented to such waiver.  Upon any such waiver, the default covered
thereby shall be deemed to be cured for all purposes of this Indenture and the
Company, the Trustee and the holders of the Securities shall be restored to
their former positions and rights hereunder, respectively; but no such waiver
shall extend to any subsequent or other default or impair any right consequent
thereon.  Whenever any default or Event of Default hereunder shall have been
waived as permitted by this





                                       38

Section 5.07, said default or Event of Default shall for all purposes of the
Securities and this Indenture be deemed to have been cured and to be not
continuing.

                 SECTION 5.08     Notice of Defaults.

                 The Trustee shall, within 90 days after the occurrence of a
default with respect to the Securities known to a Responsible Officer, mail to
all Securityholders, as the names and addresses of such holders appear upon the
Security Register, notice of all defaults known to the Trustee, unless such
defaults shall have been cured before the giving of such notice (the term
"defaults" for the purpose of this Section 5.08 being hereby defined to be the
events specified in clauses (a), (b), (c), (d) and (e) of Section 5.01, not
including periods of grace, if any, provided for therein, and irrespective of
the giving of written notice specified in clause (c) of Section 5.01); and
provided that, except in the case of default in the payment of the principal of
or premium, if any, or interest on any of the Securities, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee, or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determines that the withholding of such
notice is in the interests of the Securityholders; and provided further, that
in the case of any default of the character specified in Section 5.01(c) no
such notice to Securityholders shall be given until at least 60 days after the
occurrence thereof but shall be given within 90 days after such occurrence.

                 SECTION 5.09  Undertaking to Pay Costs.

                 All parties to this Indenture agree, and each holder of any
Security by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for
any action taken or omitted by it as Trustee, the filing by any party litigant
in such suit of an undertaking to pay the costs of such suit, and that such
court may in its discretion assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in such suit, having
due regard to the merits and good faith of the claims or defenses made by such
party litigant; but the provisions of this Section 5.09 shall not apply to any
suit instituted by the Trustee, to any suit instituted by any Securityholder,
or group of Securityholders, holding in the aggregate more than 10% in
aggregate principal amount of the Securities outstanding, or to any suit
instituted by any Securityholder for the enforcement of the payment of the
principal of (or premium, if any) or interest on any Security against the
Company on or after the same shall have become due and payable.

                                   ARTICLE VI

                             CONCERNING THE TRUSTEE

                 SECTION 6.01     Duties and Responsibilities of Trustee.

                 With respect to the holders of the Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default and
after the curing or waiving of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture.  In case an Event of Default has occurred (which has
not been cured or waived) the Trustee shall exercise such of the rights and
powers vested in it by this Indenture, and use the same degree of care and
skill in their exercise, as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs.

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

                 (a)      prior to the occurrence of an Event of Default and
                          after the curing or waiving of all Events of Default
                          which may have occurred,

                          (1)     the duties and obligations of the Trustee
                                  shall be determined solely by the express
                                  provisions of this Indenture, and the Trustee
                                  shall not be liable except for the
                                  performance of such duties and obligations as
                                  are specifically set forth in this Indenture,
                                  and no implied covenants or obligations shall
                                  be read into this Indenture against the
                                  Trustee; and

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





                                       40

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

                 (c)      the Trustee shall not be liable with respect to any
                          action taken or omitted to be taken by it in good
                          faith, in accordance with the direction of the
                          Securityholders pursuant to Section 5.07, relating to
                          the time, method and place of conducting any
                          proceeding for any remedy available to the Trustee,
                          or exercising any trust or power conferred upon the
                          Trustee, under this Indenture.

                 None of the provisions contained in this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if there is reasonable ground for believing
that the repayment of such funds or liability is not reasonably assured to it
under the terms of this Indenture or adequate indemnity against such risk is
not reasonably assured to it.

                 SECTION 6.02     Reliance on Documents, Opinions, etc.

                 Except as otherwise provided in Section 6.01:

                 (a)      the Trustee may rely and shall be protected in acting
                          or refraining from acting upon any resolution,
                          certificate, statement, instrument, opinion, report,
                          notice, request, consent, order, bond, note,
                          debenture or other paper or document believed by it
                          to be genuine and to have been signed or presented by
                          the proper party or parties;

                 (b)      any request, direction, order or demand of the
                          Company mentioned herein may be sufficiently
                          evidenced by an Officers' Certificate (unless other
                          evidence in respect thereof be herein specifically
                          prescribed); and any Board Resolution may be
                          evidenced to the Trustee by a copy thereof certified
                          by the Secretary or an Assistant Secretary of the
                          Company;

                 (c)      the Trustee may consult with counsel of its selection
                          and any advice or Opinion of Counsel shall be full
                          and complete authorization and protection in respect
                          of any action taken or suffered omitted by it
                          hereunder in good faith and in accordance with such
                          advice or Opinion of Counsel;

<PAGE>   50

                 (d)      the Trustee shall be under no obligation to exercise
                          any of the rights or powers vested in it by this
                          Indenture at the request, order or direction of any
                          of the Securityholders, pursuant to the provisions of
                          this Indenture, unless such Securityholders shall
                          have offered to the Trustee reasonable security or
                          indemnity against the costs, expenses and liabilities
                          which may be incurred therein or thereby;

                 (e)      the Trustee shall not be liable for any action taken
                          or omitted by it in good faith and believed by it to
                          be authorized or within the discretion or rights or
                          powers conferred upon it by this Indenture; nothing
                          contained herein shall, however, relieve the Trustee
                          of the obligation, upon the occurrence of an Event of
                          Default (that has not been cured or waived), to
                          exercise such of the rights and powers vested in it
                          by this Indenture, and to use the same degree of care
                          and skill in their exercise, as a prudent man would
                          exercise or use under the circumstances in the
                          conduct of his own affairs;

                 (f)      the Trustee shall not be bound to make any
                          investigation into the facts or matters stated in any
                          resolution, certificate, statement, instrument,
                          opinion, report, notice, request, consent, order,
                          approval, bond, debenture, coupon or other paper or
                          document, unless requested in writing to do so by the
                          holders of a majority in aggregate principal amount
                          of the outstanding Securities; provided, however,
                          that if the payment within a reasonable time to the
                          Trustee of the costs, expenses or liabilities likely
                          to be incurred by it in the making of such
                          investigation is, in the opinion of the Trustee, not
                          reasonably assured to the Trustee by the security
                          afforded to it by the terms of this Indenture, the
                          Trustee may require reasonable indemnity against such
                          expense or liability as a condition to so proceeding;
                          and

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

                 SECTION 6.03     No Responsibility for Recitals, etc.

                 The recitals contained herein and in the Securities (except in
the certificate of authentication of the Trustee or the Authenticating Agent)
shall be taken as the statements of the Company and the Trustee and the
Authenticating Agent assume no responsibility for the correctness of the same.
The Trustee and the Authenticating Agent make no representations as to the
validity or sufficiency of this Indenture or of the Securities.  The Trustee
and the Authenticating Agent shall not be accountable for the use or
application by the Company of any Securities or the proceeds of any Securities
authenticated and delivered by the Trustee or the Authenticating Agent in
conformity with the provisions of this Indenture.  The Trustee shall not be
charged with knowledge of any default or Event of Default under Section 5.01(a)
or (b) relating to Other Debentures unless (i) a Responsible Officer of the
Trustee assigned to its Principal Office shall have actual knowledge thereof or
(ii) the Company, any Securityholder or the holder of any Other Debenture shall
have given the Trustee written notice thereof in accordance with Section 13.04.

                 SECTION 6.04    Trustee, Authenticating Agent, Paying Agents,
                                 Transfer Agents or Registrar May Own
                                 Securities.

                 The Trustee or any Authenticating Agent or any paying agent or
any transfer agent or any Security registrar, in its individual or any other
capacity, may become the owner or pledgee of Securities with the same rights it
would have if it were not Trustee, Authenticating Agent, paying agent, transfer
agent or Security registrar.

                 SECTION 6.05     Moneys to be Held in Trust.

                 Subject to the provisions of Section 11.04, all moneys
received by the Trustee or any paying agent shall, until used or applied as
herein provided, be held in trust for the purpose for which they were received,
but need not be segregated from other funds except to the extent required by
law.  The Trustee and any paying agent shall be under no liability for interest
on any money received by it hereunder except as otherwise agreed in writing
with the Company.  So long as no Event of Default shall have occurred and be
continuing, all interest allowed on any such moneys shall be paid from time to
time upon the written order of the Company, signed by the Chairman of the Board
of Directors, the President or a Vice President or the Treasurer or an
Assistant Treasurer of the Company.

                 SECTION 6.06     Compensation and Expenses of Trustee.





                                       43
<PAGE>   52

                 The Company, as issuer of Securities under this Indenture,
covenants and agrees to pay to the Trustee from time to time, and the Trustee
shall be entitled to, such compensation as shall be agreed to in writing
between the Company and the Trustee (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express
trust), and the Company will pay or reimburse the Trustee upon its request for
all reasonable expenses, disbursements and advances incurred or made by the
Trustee in accordance with any of the provisions of this Indenture (including
the reasonable compensation and the expenses and disbursements of its counsel
and of all persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from its negligence or bad faith.  The
Company also covenants to indemnify each of the Trustee or any predecessor
Trustee (and its officers, agents, directors and employees) for, and to hold it
harmless against, any and all loss, damage, claim, liability or expense
including taxes (other than taxes based on the income of the Trustee) incurred
without negligence or bad faith on the part of the Trustee and arising out of
or in connection with the acceptance or administration of this trust, including
the costs and expenses of defending itself against any claim of liability in
the premises.  The obligations of the Company under this Section 6.06 to
compensate and indemnify the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall constitute additional indebtedness
hereunder.  Such additional indebtedness shall be secured by a lien prior to
that of the Securities upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the benefit of the holders of
particular Securities.

                 Without prejudice to any other rights available to the Trustee
under applicable law, when the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.01(d) or Section
5.01(e), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law.

                 The provisions of this Section shall survive the termination
of this Indenture.

                 SECTION 6.07     Officers' Certificate as Evidence.

                 Except as otherwise provided in Sections 6.01 and 6.02,
whenever in the administration of the provisions of this Indenture the Trustee
shall deem it necessary or desirable that a matter be proved or established
prior to taking or omitting any action hereunder, such matter (unless other
evidence in respect thereof is herein specifically prescribed) may, in the
absence of negligence or bad faith on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certifi-





                                       44
<PAGE>   53

cate delivered to the Trustee, and such certificate, in the absence of
negligence or bad faith on the part of the Trustee, shall be full warrant to
the Trustee for any action taken or omitted by it under the provisions of this
Indenture upon the faith thereof.

                 SECTION 6.08     Conflicting Interest of Trustee.

                 If the Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee
and the Company shall in all respects comply with the provisions of Section
310(b) of the Trust Indenture Act, subject to the penultimate paragraph
thereof.  The Declaration and the Guarantee are hereby excluded for purposes of
Section 310(b)(i) of the Trust Indenture Act.

                 SECTION 6.09     Eligibility of Trustee.

                 The Trustee hereunder shall at all times be a corporation
organized and doing business under the laws of the United States of America or
any state or territory thereof or of the District of Columbia or a corporation
or other Person permitted to act as trustee by the Commission authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least 50 million U.S.  dollars ($50,000,000) and subject to
supervision or examination by federal, state, territorial, or District of
Columbia authority.  If such corporation publishes reports of condition at
least annually, pursuant to law or to the requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section 6.09
the combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of
condition so published.

                 The Company may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Company, serve as
Trustee.

                 In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 6.09, the Trustee shall resign
immediately in the manner and with the effect specified in Section 6.10.

                 SECTION 6.10     Resignation or Removal of Trustee.

                 (a)      The Trustee, or any trustee or trustees hereafter
                          appointed, may at any time resign by giving written
                          notice of such resignation to the Company and by
                          mailing notice thereof to the holders of the
                          Securities at their addresses as they shall appear on
                          the Security register.  Upon receiving such notice of
                          resignation, the Company shall promptly

                          appoint a successor trustee or trustees by written
                          instrument, in duplicate, one copy of which instrument
                          shall be delivered to the resigning Trustee and one
                          copy to the successor trustee.  If no successor
                          trustee shall have been so appointed and have accepted
                          appointment within 60 days after the mailing of such
                          notice of resignation to the affected Securityholders,
                          the resigning Trustee may petition any court of
                          competent jurisdiction for the appointment of a
                          successor trustee, or any Securityholder who has been
                          a bona fide holder of a Security for at least six
                          months may, subject to the provisions of Section 5.09,
                          on behalf of himself and all others similarly
                          situated, petition any such court for the appointment
                          of a successor trustee.  Such court may thereupon,
                          after such notice, if any, as it may deem proper and
                          prescribe, appoint a successor trustee.

                 (b)      In case at any time any of the following shall occur:

                          (1)     the Trustee shall fail to comply with the
                                  provisions of Section 6.08 after written
                                  request therefor by the Company or by any
                                  Securityholder who has been a bona fide
                                  holder of a Security or Securities for at
                                  least six months, or

                          (2)     the Trustee shall cease to be eligible in
                                  accordance with the provisions of Section
                                  6.09 and shall fail to resign after written
                                  request therefor by the Company or by any
                                  such Securityholder, or

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

                          then, in any such case, the Company may remove the
                          Trustee and appoint a successor trustee by written
                          instrument, in duplicate, one copy of which
                          instrument shall be delivered to the Trustee so
                          removed and one copy to the successor trustee, or,
                          subject to the provisions of Section 5.09, any
                          Securityholder who has been a bona fide holder of a
                          Security for at least six months may, on behalf





                                       46
<PAGE>   55

                          of himself and all others similarly situated, petition
                          any court of competent jurisdiction for the removal of
                          the Trustee and the appointment of a successor
                          trustee.  Such court may thereupon, after such notice,
                          if any, as it may deem proper and prescribe, remove
                          the Trustee and appoint a successor trustee.

                 (c)      The holders of a majority in aggregate principal
                          amount of the Securities at the time outstanding may
                          at any time remove the Trustee and nominate a
                          successor trustee, which shall be deemed appointed as
                          successor trustee unless within 10 days after such
                          nomination the Company objects thereto or if no
                          successor trustee shall have been so appointed and
                          shall have accepted appointment within 30 days after
                          such removal, in which case the Trustee so removed or
                          any Securityholder, upon the terms and conditions and
                          otherwise as in subsection (a) of this Section 6.10
                          provided, may petition any court of competent
                          jurisdiction for an appointment of a successor
                          trustee.

                 (d)      Any resignation or removal of the Trustee and
                          appointment of a successor trustee pursuant to any of
                          the provisions of this Section 6.10 shall become
                          effective upon acceptance of appointment by the
                          successor trustee as provided in Section 6.11.

                 SECTION 6.11     Acceptance by Successor Trustee.

                 Any successor trustee appointed as provided in Section 6.10
shall execute, acknowledge and deliver to the Company and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the retiring trustee shall become effective and such
successor trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Company or of the successor
trustee, the trustee ceasing to act shall, upon payment of any amounts then due
it pursuant to the provisions of Section 6.06, execute and deliver an
instrument transferring to such successor trustee all the rights and powers of
the trustee so ceasing to act and shall duly assign, transfer and deliver to
such successor trustee all property and money held by such retiring trustee
thereunder.  Upon request of any such successor trustee, the Company shall
execute any and all instruments in writing for more fully and certainly vesting
in and confirming to such successor trustee all such rights and powers.  Any
trustee ceasing to act shall, nevertheless, retain a lien upon all property or
funds held or





                                       47
<PAGE>   56

collected by such trustee to secure any amounts then due it pursuant to the
provisions of Section 6.06.

                 No successor trustee shall accept appointment as provided in
this Section 6.11 unless at the time of such acceptance such successor trustee
shall be qualified under the provisions of Section 6.08 and eligible under the
provisions of Section 6.09.

                 Upon acceptance of appointment by a successor trustee as
provided in this Section 6.11, the Company shall mail notice of the succession
of such trustee hereunder to the holders of Securities at their addresses as
they shall appear on the Security register.  If the Company fails to mail such
notice within 10 days after the acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Company.

                 SECTION 6.12     Succession by Merger, etc.

                 Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder without the execution or filing of any paper or any further act on
the part of any of the parties hereto.

                 In case at the time such successor to the Trustee shall
succeed to the trusts created by this Indenture any Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt
the certificate of authentication of any predecessor trustee, and deliver such
Securities so authenticated; and in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may
authenticate such Securities either in the name of any predecessor hereunder or
in the name of the successor trustee; and in all such cases such certificates
shall have the full force which the Securities or this Indenture elsewhere
provides that the certificate of the Trustee shall have; provided, however,
that the right to adopt the certificate of authentication of any predecessor
Trustee or authenticate Securities in the name of any predecessor Trustee shall
apply only to its successor or successors by merger, conversion or
consolidation.

                 SECTION 6.13     Limitation on Rights of Trustee as a
                                  Creditor.

                 The Trustee shall comply with Section 311(a) of the Trust
Indenture Act, excluding any creditor relationship described in Section 311(b)
of the Trust Indenture Act.  A Trustee





                                       48
<PAGE>   57

who has resigned or been removed shall be subject to Section 311(a) of the
Trust Indenture Act to the extent included therein.

                 SECTION 6.14     Authenticating Agents.

                 There may be one or more Authenticating Agents appointed by
the Trustee upon the request of the Company with power to act on its behalf and
subject to its direction in the authentication and delivery of Securities
issued upon exchange or transfer thereof as fully to all intents and purposes
as though any such Authenticating Agent had been expressly authorized to
authenticate and deliver Securities; provided, that the Trustee shall have no
liability to the Company for any acts or omissions of the Authenticating Agent
with respect to the authentication and delivery of Securities.  Any such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States or of any state or territory
thereof or of the District of Columbia authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of at least
$5,000,000 and being subject to supervision or examination by federal, state,
territorial or District of Columbia authority.  If such corporation publishes
reports of condition at least annually pursuant to law or the requirements of
such authority, then for the purposes of this Section 6.14 the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published.  If
at any time an Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect herein specified in this Section.

                 Any corporation into which any Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any
Authenticating Agent shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of any Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, if such
successor corporation is otherwise eligible under this Section 6.14 without the
execution or filing of any paper or any further act on the part of the parties
hereto or such Authenticating Agent.

                 Any Authenticating Agent may at any time resign by giving
written notice of resignation to the Trustee and to the Company.  The Trustee
may at any time terminate the agency of any Authenticating Agent by giving
written notice of termination to such Authenticating Agent and to the Company.
Upon receiving such a notice of resignation or upon such a termination, or in
case at any time any Authenticating Agent shall cease to be eligible under this
Section 6.14, the Trustee may, and upon the request of the Company shall,
promptly appoint a successor





                                       49
<PAGE>   58

Authenticating Agent eligible under this Section 6.14, shall give written
notice of such appointment to the Company and shall mail notice of such
appointment to all Securityholders as the names and addresses of such holders
appear on the Security Register.  Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all rights,
powers, duties and responsibilities of its predecessor hereunder, with like
effect as if originally named as Authenticating Agent herein.

                 The Company, as borrower, agrees to pay to any Authenticating
Agent from time to time reasonable compensation for its services.  Any
Authenticating Agent shall have no responsibility or liability for any action
taken by it as such in accordance with the directions of the Trustee.


                                  ARTICLE VII

                         CONCERNING THE SECURITYHOLDERS

                 SECTION 7.01     Action by Securityholders.

                 Whenever in this Indenture it is provided that the holders of
a specified percentage in aggregate principal amount of the Securities may take
any action (including the making of any demand or request, the giving of any
notice, consent or waiver or the taking of any other action) the fact that at
the time of taking any such action the holders of such specified percentage
have joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by such Securityholders in person or by
agent or proxy appointed in writing, or (b) by the record of such holders of
Securities voting in favor thereof at any meeting of such Securityholders duly
called and held in accordance with the provisions of Article VIII, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of such Securityholders.

                 If the Company shall solicit from the Securityholders any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for the determination of
Securityholders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other action or to revoke any such
action, but the Company shall have no obligation to do so.  If such a record
date is fixed, such request, demand, authorization, direction, notice, consent,
waiver or other action or revocation may be given before or after the record
date, but only the Securityholders of record at the close of business on the
record date shall be deemed to be Securityholders for the purposes of
determining whether Securityholders of the requisite proportion of
Outstanding





                                       50
<PAGE>   59

Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other action, and for that
purpose the Outstanding Securities shall be computed as of the record date;
provided, however, that no such authorization, agreement or consent by such
Securityholders on the record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Indenture not later than
six months after the record date.

                 SECTION 7.02     Proof of Execution by Securityholders.

                 Subject to the provisions of Section 6.01, 6.02 and 8.05,
proof of the execution of any instrument by a Securityholder or his agent or
proxy shall be sufficient if made in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee.  The ownership of Securities shall be proved by
the Security Register or by a certificate of the Security registrar.  The
Trustee may require such additional proof of any matter referred to in this
Section as it shall deem necessary.

                 The record of any Securityholders' meeting shall be proved in
the manner provided in Section 8.06.

                 SECTION 7.03     Who Are Deemed Absolute Owners.

                 Prior to due presentment for registration of transfer of any
Security, the Company, the Trustee, any Authenticating Agent, any paying agent,
any transfer agent and any Security registrar may deem the person in whose name
such Security shall be registered upon the Security Register to be, and may
treat him as, the absolute owner of such Security (whether or not such Security
shall be overdue) for the purpose of receiving payment of or on account of the
principal of and premium, if any, and (subject to Section 2.06) interest on
such Security and for all other purposes; and neither the Company nor the
Trustee nor any Authenticating Agent nor any paying agent nor any transfer
agent nor any Security registrar shall be affected by any notice to the
contrary.  All such payments so made to any holder for the time being or upon
his order shall be valid, and, to the extent of the sum or sums so paid,
effectual to satisfy and discharge the liability for moneys payable upon any
such Security.

                 SECTION 7.04     Securities Owned by Company Deemed Not
                                  Outstanding.

                 In determining whether the holders of the requisite aggregate
principal amount of Securities have concurred in any direction, consent or
waiver under this Indenture, Securities which are owned by the Company or any
other obligor on the Securities or by any Person directly or indirectly
controlling or





                                       51
<PAGE>   60

controlled by or under direct or indirect common control with the Company or
any other obligor on the Securities shall be disregarded and deemed not to be
outstanding for the purpose of any such determination; provided that for the
purposes of determining whether the Trustee shall be protected in relying on
any such direction, consent or waiver, only Securities which a Responsible
Officer actually knows are so owned shall be so disregarded.  Securities so
owned which have been pledged in good faith may be regarded as outstanding for
the purposes of this Section 7.04 if the pledgee shall establish to the
satisfaction of the Trustee the pledgee's right to vote such Securities and
that the pledgee is not the Company or any such other obligor or Person
directly or indirectly controlling or controlled by or under direct or indirect
common control with the Company or any such other obligor.  In the case of a
dispute as to such right, any decision by the Trustee taken upon the advice of
counsel shall be full protection to the Trustee.

                 SECTION 7.05     Revocation of Consents; Future Holders Bound.

                 At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 7.01, of the taking of any action by the
holders of the percentage in aggregate principal amount of the Securities
specified in this Indenture in connection with such action, any holder of a
Security (or any Security issued in whole or in part in exchange or
substitution therefor), subject to Section 7.01, the serial number of which is
shown by the evidence to be included in the Securities the holders of which
have consented to such action may, by filing written notice with the Trustee at
its principal office and upon proof of holding as provided in Section 7.02,
revoke such action so far as concerns such Security (or so far as concerns the
principal amount represented by any exchanged or substituted Security).  Except
as aforesaid any such action taken by the holder of any Security shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Security, and of any Security issued in exchange or substitution
therefor, irrespective of whether or not any notation in regard thereto is made
upon such Security or any Security issued in exchange or substitution therefor.


                                  ARTICLE VIII

                           SECURITYHOLDERS' MEETINGS

                 SECTION 8.01     Purposes of Meetings.

                 A meeting of Securityholders may be called at any time and
from time to time pursuant to the provisions of this Article VIII for any of
the following purposes:





                                       52

                 (a)      to give any notice to the Company or to the Trustee,
                          or to give any directions to the Trustee, or to
                          consent to the waiving of any default hereunder and
                          its consequences, or to take any other action
                          authorized to be taken by Securityholders pursuant to
                          any of the provisions of Article V;

                 (b)      to remove the Trustee and nominate a successor trustee
                          pursuant to the provisions of Article VI;

                 (c)      to consent to the execution of an indenture or
                          indentures supplemental hereto pursuant to the
                          provisions of Section 9.02; or

                 (d)      to take any other action authorized to be taken by or
                          on behalf of the holders of any specified aggregate
                          principal amount of such Securities under any other
                          provision of this Indenture or under applicable law.

                 SECTION 8.02     Call of Meetings by Trustee.

                 The Trustee may at any time call a meeting of Securityholders
to take any action specified in Section 8.01, to be held at such time and at
such place in the Borough of Manhattan, The City of New York, as the Trustee
shall determine.  Notice of every meeting of the Securityholders, setting forth
the time and the place of such meeting and in general terms the action proposed
to be taken at such meeting, shall be mailed to holders of Securities at their
addresses as they shall appear on the Securities Register.  Such notice shall
be mailed not less than 20 nor more than 180 days prior to the date fixed for
the meeting.

                 SECTION 8.03     Call of Meetings by Company or
                                  Securityholders.

                 In case at any time the Company pursuant to a resolution of
the Board of Directors, or the holders of at least 10% in aggregate principal
amount of the Securities then outstanding, shall have requested the Trustee to
call a meeting of Securityholders, by written request setting forth in
reasonable detail the action proposed to be taken at the meeting, and the
Trustee shall not have mailed the notice of such meeting within 20 days after
receipt of such request, then the Company or such Securityholders may determine
the time and the place in said Borough of Manhattan for such meeting and may
call such meeting to take any action authorized in Section 8.01, by mailing
notice thereof as provided in Section 8.02.

                 SECTION 8.04     Qualifications for Voting.

                 To be entitled to vote at any meeting of Securityholders a
Person shall (a) be a holder of one or more Securities or (b) a Person
appointed by an instrument in writing as proxy by a holder of one or more
Securities.  The only Persons who shall be entitled to be present or to speak

meeting and their counsel and any representatives of the Trustee and its
counsel and any representatives of the Company and its counsel.

                 SECTION 8.05     Regulations.

                 Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Securityholders, in regard to proof of the holding of Securities and
of the appointment of proxies, and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates
and other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think fit.

                 The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Securityholders as provided in Section 8.03, in which case
the Company or the Securityholders calling the meeting, as the case may be,
shall in like manner appoint a temporary chairman.  A permanent chairman and a
permanent secretary of the meeting shall be elected by majority vote of the
meeting.

                 Subject to the provisions of Section 8.04, at any meeting each
holder of Securities or proxy therefor shall be entitled to one vote for each
$1,000 principal amount of Securities held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not outstanding and ruled by the chairman of the meeting
to be not outstanding.  The chairman of the meeting shall have no right to vote
other than by virtue of Securities held by him or instruments in writing as
aforesaid duly designating him as the person to vote on behalf of other
Securityholders.  Any meeting of Securityholders duly called pursuant to the
provisions of Section 8.02 or 8.03 may be adjourned from time to time by a
majority of those present[, whether or not constituting a quorum,] and the
meeting may be held as so adjourned without further notice.

                 The Persons entitled to vote a majority in principal amount of
the outstanding Securities shall constitute a quorum for a meeting of
Securityholders; provided, however, that if any action is to be taken at such
meeting with respect to a consent,





                                       54

waiver, request, demand, notice, authorization, direction or other action which
may be given by the holders of not less than a specified percentage in
principal amount of the outstanding Securities, the Persons holding or
representing such specified percentage in principal amount of the outstanding
Securities will constitute a quorum.  In the absence of a quorum within 30
minutes of the time appointed for any such meeting, the meeting shall, if
convened at the request of holders of Securities, be dissolved.  In any other
case the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
meeting.  In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10
days as determined by the chairman of the meeting prior to the adjournment of
such adjourned meeting.  Notice of the reconvening of any adjourned meeting
shall be given as provided in Section 8.02, except that such notice need be
given only once not less than five days prior to the date on which the meeting
is scheduled to be reconvened.  Notice of the reconvening of an adjourned
meeting shall state expressly the percentage, as provided above, of the
principal amount of the outstanding Securities which shall constitute a quorum.

                 Except as limited by the first proviso to the first paragraph
of Section 9.02, any resolution presented to a meeting or adjourned meeting
duly reconvened at which a quorum is present as aforesaid may be adopted by the
affirmative vote of the holders of a majority in principal amount of the
outstanding Securities; provided, however, that, except as limited by the first
proviso to the first paragraph of Section 9.02, any resolution with respect to
any consent, waiver, request, demand, notice, authorization, direction or other
action which this Indenture expressly provides may be given by the holders of
not less than a specified percentage in principal amount of the outstanding
Securities may be adopted at a meeting or an adjourned meeting duly reconvened
and at which a quorum is present as aforesaid only by the affirmative vote of
the holders of not less than such specified percentage in principal amount of
the outstanding Securities.

                 Any resolution passed or decision taken at any meeting of
Securityholders duly held in accordance with this Section shall be binding on
all the holders of Securities whether or not present or represented at the
meeting.

                 SECTION 8.06     Voting.

                 The vote upon any resolution submitted to any meeting of
holders of Securities shall be by written ballots on which shall be subscribed
the signatures of such holders or of their representatives by proxy and the
serial number or numbers of the Securities held or represented by them.  The
permanent chairman





                                       55
<PAGE>   64

of the meeting shall appoint two inspectors of votes who shall count all votes
cast at the meeting for or against any resolution and who shall make and file
with the secretary of the meeting their verified written reports in triplicate
of all votes cast at the meeting.  A record in duplicate of the proceedings of
each meeting of Securityholders shall be prepared by the secretary of the
meeting and there shall be attached to said record the original reports of the
inspectors of votes on any vote by ballot taken thereat and affidavits by one
or more persons having knowledge of the facts setting forth a copy of the
notice of the meeting and showing that said notice was mailed as provided in
Section 8.02.  The record shall show the serial numbers of the Securities
voting in favor of or against any resolution.  The record shall be signed and
verified by the affidavits of the permanent chairman and secretary of the
meeting and one of the duplicates shall be delivered to the Company and the
other to the Trustee to be preserved by the Trustee, the latter to have
attached thereto the ballots voted at the meeting.  The holders of the Series A
Capital Securities and the Series B Capital Securities shall vote for all
purposes as a single class.

                 Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                          the protection of the Securityholders, and to make
                          the occurrence, or the occurrence and continuance, of

                          other defaults) or may provide for an immediate
                          enforcement upon such default or may limit the
                          remedies available to the Trustee upon such default;

                          exchangeability of such Securities with the
                          Securities issued hereunder in fully registered form
                          and to make all appropriate changes for such purpose;

                 (d)      to cure any ambiguity or to correct or supplement any
                          provision contained herein or in any supplemental
                          indenture which may be defective or inconsistent with
                          any other provision contained herein or in any

                          shall not materially adversely affect the interests of

                          on Securities, minimum denominations and all other
                          matters required pursuant to Section 2.07 or
                          otherwise necessary, desirable or appropriate in
                          connection with the issuance of Securities to holders
                          of Capital Securities in the event of a distribution
                          of Securities by AMCORE Capital Trust following a
                          Dissolution Event;

                 (g)      to qualify or maintain qualification of this Indenture
                          under the Trust Indenture Act; or

the execution of any supplemental indenture to effect such amendment, to make
any further appropriate agreements and





                                       57
<PAGE>   66

stipulations which may be therein contained and to accept the conveyance,
transfer and assignment of any property thereunder, but the Trustee shall not
be obligated to, but may in its discretion, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

                 Any amendment to the Indenture authorized by the provisions of
this Section 9.01 may be executed by the Company and the Trustee without the
consent of the holders of any of the Securities at the time outstanding,
notwithstanding any of the provisions of Section 9.02.

                 SECTION 9.02     With Consent of Securityholders.

                 With the consent (evidenced as provided in Section 7.01) of
the holders of a majority in aggregate principal amount of the Securities at
the time outstanding, the Company, when authorized by a Board Resolution, and
the Trustee may from time to time and at any time amend the Indenture for the
purpose of adding any provisions to or changing in any manner or eliminating
any of the provisions of this Indenture or of modifying in any manner the
rights of the holders of the Securities; provided, however, that no such
amendment shall without the consent of the holders of each Security then
outstanding and affected thereby (i) extend the Maturity Date of any Security,
or reduce the rate or extend the time of payment of interest thereon (except as
contemplated by Article XVI), or reduce the principal amount thereof, or reduce
any amount payable on redemption thereof, or make the principal thereof or any
interest or premium thereon payable in any coin or currency other than that
provided in the Securities, or impair or affect the right of any Securityholder
to institute suit for payment thereof, or (ii) reduce the aforesaid percentage
of Securities the holders of which are required to consent to any such
amendment to the Indenture, provided, however, that if the Securities are held
by AMCORE Capital Trust, such amendment shall not be effective until the
holders of a majority in liquidation amount of Trust Securities shall have
consented to such amendment; provided, further, that if the consent of the
holder of each outstanding Security is required, such amendment shall not be
effective until each holder of the Trust Securities shall have consented to
such amendment.

                 Upon the request of the Company accompanied by a copy of a
resolution of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any supplemental indenture affecting
such amendment, and upon the filing with the Trustee of evidence of the consent
of Securityholders as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which





                                       58
<PAGE>   67

case the Trustee may in its discretion, but shall not be obligated to, enter
into such supplemental indenture.

                 Promptly after the execution by the Company and the Trustee of
any supplemental indenture pursuant to the provisions of this Section, the
Trustee shall transmit by mail, first class postage prepaid, a notice, prepared
by the Company, setting forth in general terms the substance of such
supplemental indenture, to the Securityholders as their names and addresses
appear upon the Security Register.  Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

                 It shall not be necessary for the consent of the
Securityholders under this Section 9.02 to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such consent
shall approve the substance thereof.

                 SECTION 9.03    Compliance with Trust Indenture Act; Effect of
                                 Supplemental Indentures.

                 Any supplemental indenture executed pursuant to the provisions
of this Article IX shall comply with the Trust Indenture Act.  Upon the
execution of any supplemental indenture pursuant to the provisions of this
Article IX, this Indenture shall be and be deemed to be modified and amended in
accordance therewith and the respective rights, limitations of rights,
obligations, duties and immunities under this Indenture of the Trustee, the
Company and the holders of Securities shall thereafter be determined, exercised
and enforced hereunder subject in all respects to such modifications and
amendments and all the terms and conditions of any such supplemental indenture
shall be and be deemed to be part of the terms and conditions of this Indenture
for any and all purposes.

                 SECTION 9.04     Notation on Securities.

                 Securities authenticated and delivered after the execution of
any supplemental indenture affecting such series pursuant to the provisions of
this Article IX may bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture.  If the Company or the
Trustee shall so determine, new Securities so modified as to conform, in the
opinion of the Trustee and the Board of Directors, to any modification of this
Indenture contained in any such supplemental indenture may be prepared and
executed by the Company, authenticated by the Trustee or the Authenticating
Agent and delivered in exchange for the Securities then outstanding.

                 The Trustee, subject to the provisions of Sections 6.01 and
6.02, may receive an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any supplemental indenture executed pursuant hereto
complies with the requirements of this Article IX.

                 The Trustee may receive an Opinion of Counsel as conclusive
evidence that any supplemental indenture executed pursuant to this Article is
authorized or permitted by, and conforms to, the terms of this Article and that
it is proper for the Trustee under the provisions of this Article to join in
the execution thereof.

                                  Terms.

                 Nothing contained in this Indenture or in any of the
Securities shall prevent any consolidation or merger of the Company with or
into any other Person (whether or not affiliated with the Company, as the case
may be), or successive consolidations or mergers in which the Company, or its
successor or successors, as the case may be, shall be a party or parties, or

authorized to acquire and operate the same; provided, that (a) the Company is
the surviving Person, or the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
conveyance, transfer or lease of property is made is a Person organized and
existing under the laws of the United States or any State thereof or the
District of Columbia, and (b) upon any such consolidation, merger, sale,
conveyance, transfer or lease, the due and punctual payment of the principal of

conditions of this Indenture to be kept or performed by the Company shall be
expressly assumed, by supplemental indenture (which shall conform to the
provisions of the Trust Indenture Act, as then in effect) satisfactory in form
to the Trustee executed and delivered to the Trustee by the Person formed by
such consolidation, or into which the Company, shall have been merged, or by
the Person which shall have ac-

it had been named herein as the party of the first part, and the Company
thereupon shall be relieved of any further liability or obligation hereunder or
upon the Securities.  Such successor Person thereupon may cause to be signed,
and may issue either in its own name or in the name of AMCORE Corporation, any

                 SECTION 11.01    Discharge of Indenture.

                 When (a) the Company shall deliver to the Trustee for

been replaced or paid as provided in Section 2.08) and not theretofore
cancelled, or (b) all the Securities not theretofore cancelled or delivered to

U.S. Government Obligations have been deposited with the Trustee, of all sums
due and to become due thereon for principal, premium, if any, and interest.

tax, fee or other charge imposed on or assessed against the U.S.  Government
Obligations deposited pursuant to Section 11.05 or the principal and interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the holders of outstanding Securities.

                          Opinion of Counsel to the effect that the exercise of
                          the option under this Section 11.05 would not cause

                 (3)      no Default or Event of Default with respect to the

                          same times as would have been the case if such option
                          had not been exercised, and such opinion shall be
                          based on a statute so providing or be accompanied by
                          a private letter ruling to that effect received from

Company to enforce such Property Trustee's rights under this Indenture without
first instituting any legal proceedings against such Property Trustee or any
other person or entity.  Notwithstanding the foregoing, if an Event of Default

the Company to pay principal of or premium, if any, or interest on the
Securities when due, the Company acknowledges that a holder of Capital
Securities may directly institute a proceeding for enforcement of payment to
such holder of the principal of or premium, if any, or interest on the
Securities having a principal amount equal to the aggregate liquidation amount
of the Capital Securities of such holder on or after the respective due date
specified in the Securities.

the time of redemption the Securities are registered as a Global Security, the

amount of such securities held for the account of its participants to be
redeemed.  The Optional Redemption Price shall be paid prior to 12:00 noon, New

part at their last addresses as the same appear on the Security Register.  Such
mailing shall be by first class mail.  The notice if mailed in the manner
herein provided shall be conclusively presumed to have been duly given, whether
or not the holder receives such notice.  In any case, failure to give such
notice by mail or any defect in the notice to the holder of any Security
designated for redemption as a whole or in part shall not affect the validity
of the proceedings for the redemption of any other Security.

                 Each such notice of redemption shall specify the CUSIP number
of the Securities to be redeemed, the date fixed for redemption, the redemption
price at which the Securities are to be redeemed (or the method by which such
redemption price is to be calculated), the place or places of payment, that
payment will be made upon presentation and surrender of the Securities, that
interest accrued to the date fixed for redemption will be paid as specified in
said notice, and that on and after said date interest thereon or on the
portions thereof to be redeemed will cease to accrue.  If less than all the
Securities are to be redeemed the notice of redemption shall specify the
numbers of the Securities to be redeemed.  In case any Security is to be
redeemed in part only, the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the
date fixed for redemption, upon surrender of such Security, a new Security or
Securities in principal amount equal to the unredeemed portion thereof will be
issued.

                 By 10:00 a.m. New York time on the redemption date specified
in the notice of redemption given as provided in this Section, the Company will
deposit with the Trustee or with one or more paying agents an amount of money
sufficient to redeem on the redemption date all the Securities so called for
redemption at the appropriate Redemption Price, together with accrued interest
to the date fixed for redemption.

                 The Company will give the Trustee notice not less than 45 days
prior to the redemption date as to the aggregate princi-





                                       71

pal amount of Securities to be redeemed and the Trustee shall select, in such
manner as in its sole discretion it shall deem appropriate and fair, the
Securities or portions thereof (in integral multiples of $1,000, except as
otherwise set forth in the applicable form of Security) to be redeemed.

                 SECTION 14.05    Payment of Securities Called for Redemption.

                 If notice of redemption has been given as provided in Section
14.04, the Securities or portions of Securities with respect to which such
notice has been given shall become due and payable on the date and at the place
or places stated in such notice at the applicable Redemption Price, together
with interest accrued to the date fixed for redemption (subject to the rights
of holders of Securities on the close of business on a regular record date in
respect of an Interest Payment Date occurring on or prior to the redemption
date), and on and after said date (unless the Company shall default in the
payment of such Securities at the Redemption Price, together with interest
accrued to said date) interest on the Securities or portions of Securities so
called for redemption shall cease to accrue.  On presentation and surrender of
such Securities at a place of payment specified in said notice, the said
Securities or the specified portions thereof shall be paid and redeemed by the
Company at the applicable Redemption Price, together with interest accrued
thereon to the date fixed for redemption (subject to the rights of holders of
Securities on the close of business on a regular record date in respect of an
Interest Payment Date occurring on or prior to the redemption date).

                 Upon presentation of any Security redeemed in part only, the
Company shall execute and the Trustee shall authenticate and make available for
delivery to the holder thereof, at the expense of the Company, a new Security
or Securities of authorized denominations, in principal amount equal to the
unredeemed portion of the Security so presented.


                                   ARTICLE XV

                          SUBORDINATION OF SECURITIES

                 SECTION 15.01    Agreement to Subordinate.

                 The Company covenants and agrees, and each holder of
Securities issued hereunder likewise covenants and agrees, that the Securities
shall be issued subject to the provisions of this Article XV; and each holder
of a Security, whether upon original issue or upon transfer or assignment
thereof, accepts and agrees to be bound by such provisions.





                                       72
<PAGE>   81

                 The payment by the Company of the principal of, premium, if
any, and interest on all Securities issued hereunder shall, to the extent and
in the manner hereinafter set forth, be subordinated and junior in right of
payment to all Senior Indebtedness, whether outstanding at the date of this
Indenture or thereafter incurred.

                 No provision of this Article XV shall prevent the occurrence
of any Default or Event of Default hereunder.

                 SECTION 15.02    Default on Senior Indebtedness.

                 In the event and during the continuation of any default by the
Company in the payment of principal, premium, interest or any other payment due
on any Senior Indebtedness, or in the event that the maturity of any Senior
Indebtedness has been accelerated because of a default, then, in either case,
no payment shall be made by the Company with respect to the principal
(including redemption payments) of or premium, if any, or interest on the
Securities.

                 In the event of the acceleration of the maturity of the
Securities, then no payment shall be made by the Company with respect to the
principal (including redemption payments) of or premium, if any, or interest on
the Securities until the holders of all Senior Indebtedness outstanding at the
time of such acceleration shall receive payment in full of such Senior
Indebtedness (including any amounts due upon acceleration).

                 In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee when such payment is prohibited by the
preceding paragraphs of this Section 15.02, such payment shall be held in trust
for the benefit of, and shall be paid over or delivered to, the holders of
Senior Indebtedness or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Senior Indebtedness
may have been issued, as their respective interests may appear, but only to the
extent that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing, within 90 days of
such payment of the amounts then due and owing on such Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of such Senior Indebtedness.

                 SECTION 15.03    Liquidation; Dissolution; Bankruptcy.

                 Upon any payment by the Company or distribution of assets of
the Company of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution or winding-up or liquidation or
reorganization of the Company, whether voluntary or involuntary or in
bankruptcy, insolvency, receivership or other proceedings, all Senior
Indebtedness of the





                                       73
<PAGE>   82

Company shall first be paid in full, or payment thereof provided for in money
in accordance with its terms, before any payment is made by the Company on
account of the principal (and premium, if any) or interest on the Securities;
and upon any such dissolution or winding-up or liquidation or reorganization,
any payment by the Company, or distribution of assets of the Company of any
kind or character, whether in cash, property or securities, to which the
Securityholders or the Trustee would be entitled to receive from the Company,
except for the provisions of this Article XV, shall be paid by the Company or
by any receiver, trustee in bankruptcy, liquidating trustee, agent or other
Person making such payment or distribution, or by the Securityholders or by the
Trustee under the Indenture if received by them or it, directly to the holders
of Senior Indebtedness of the Company (pro rata to such holders on the basis of
the respective amounts of Senior Indebtedness held by such holders, as
calculated by the Company) or their representative or representatives, or to
the trustee or trustees under any indenture pursuant to which any instruments
evidencing such Senior Indebtedness may have been issued, as their respective
interests may appear, to the extent necessary to pay all such Senior
Indebtedness in full, in money or money's worth, after giving effect to any
concurrent payment or distribution to or for the holders of such Senior
Indebtedness, before any payment or distribution is made to the Securityholders
or to the Trustee.

                 In the event that, notwithstanding the foregoing, any payment
or distribution of assets of the Company of any kind or character, whether in
cash, property or securities, prohibited by the foregoing, shall be received by
the Trustee before all Senior Indebtedness is paid in full, or provision is
made for such payment in money in accordance with its terms, such payment or
distribution shall be held in trust for the benefit of and shall be paid over
or delivered to the holders of such Senior Indebtedness or their representative
or representatives, or to the trustee or trustees under any indenture pursuant
to which any instruments evidencing such Senior Indebtedness may have been
issued, as their respective interests may appear, as calculated by the Company,
for application to the payment of all Senior Indebtedness remaining unpaid to
the extent necessary to pay all such Senior Indebtedness in full in money in
accordance with its terms, after giving effect to any concurrent payment or
distribution to or for the benefit of the holders of such Senior Indebtedness.

                 For purposes of this Article XV, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment, the
payment of which is subordinated at least to the extent provided in this
Article XV with respect to the Securities to the payment of Senior Indebtedness





                                       74
<PAGE>   83

that may at the time be outstanding, provided that (i) such Senior Indebtedness
is assumed by the new corporation, if any, resulting from any such
reorganization or readjustment, and (ii) the rights of the holders of such
Senior Indebtedness are not, without the consent of such holders, altered by
such reorganization or readjustment.  The consolidation of the Company with, or
the merger of the Company into, another Person or the liquidation or
dissolution of the Company following the sale, conveyance, transfer or lease of
its property as an entirety, or substantially as an entirety, to another Person
upon the terms and conditions provided for in Article X of this Indenture shall
not be deemed a dissolution, winding-up, liquidation or reorganization for the
purposes of this Section 15.03 if such other Person shall, as a part of such
consolidation, merger, sale, conveyance, transfer or lease, comply with the
conditions stated in Article X of this Indenture.

                 SECTION 15.04    Subrogation.

                 Subject to the payment in full of all Senior Indebtedness, the
rights of the Securityholders shall be subrogated to the rights of the holders
of such Senior Indebtedness to receive payments or distributions of cash,
property or securities of the Company, as the case may be, applicable to such
Senior Indebtedness until the principal of (and premium, if any) and interest
on the Securities shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of such Senior
Indebtedness of any cash, property or securities to which the Securityholders
or the Trustee would be entitled except for the provisions of this Article XV,
and no payment over pursuant to the provisions of this Article XV to or for the
benefit of the holders of such Senior Indebtedness by Securityholders or the
Trustee, shall, as between the Company, its creditors other than holders of
Senior Indebtedness of the Company, and the holders of the Securities, be
deemed to be a payment by the Company to or on account of such Senior
Indebtedness.  It is understood that the provisions of this Article XV are and
are intended solely for the purposes of defining the relative rights of the
holders of the Securities, on the one hand, and the holders of such Senior
Indebtedness on the other hand.

                 Nothing contained in this Article XV or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as between the
Company, its creditors other than the holders of Senior Indebtedness of the
Company, and the holders of the Securities, the obligation of the Company,
which is absolute and unconditional, to pay to the holders of the Securities
the principal of (and premium, if any) and interest on the Securities as and
when the same shall become due and payable in accordance with their terms, or
is intended to or shall affect the relative rights of the holders of the
Securities and creditors of the

Company, as the case may be, other than the holders of Senior Indebtedness of
the Company, as the case may be, nor shall anything herein or therein prevent
the Trustee or the holder of any Security from exercising all remedies
otherwise permitted by applicable law upon default under the Indenture, subject
to the rights, if any, under this Article XV of the holders of such Senior
Indebtedness in respect of cash, property or securities of the Company, as the
case may be, received upon the exercise of any such remedy.

                 SECTION 15.05    Trustee to Effectuate Subordination.

                 Each Securityholder by such Securityholder's acceptance
thereof authorizes and directs the Trustee on such Securityholder's behalf to
take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article XV and appoints the Trustee such
Securityholder's attorney-in-fact for any and all such purposes.

                 SECTION 15.06    Notice by the Company.

                 The Company shall give prompt written notice to a Responsible
Officer of the Trustee of any fact known to the Company that would prohibit the
making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article XV.  Notwithstanding the
provisions of this Article XV or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts that
would prohibit the making of any payment of monies to or by the Trustee in
respect of the Securities pursuant to the provisions of this Article XV, unless
and until a Responsible Officer of the Trustee assigned to its Principal Office
shall have received written notice thereof from the Company or a holder or
holders of Senior Indebtedness or from any trustee therefor; and before the
receipt of any such written notice, the Trustee, subject to the provisions of
Article VI of this Indenture, shall be entitled in all respects to assume that
no such facts exist; provided, however, that if the Trustee shall not have
received the notice provided for in this Section 15.06 at least two Business
Days prior to the date (i) upon which by the terms hereof any money may become
payable for any purpose (including, without limitation, the payment of the
principal of (or premium, if any) or interest on any Security), or (ii) moneys
and/or U.S.  Government Obligations are deposited in trust pursuant to Article
XI then, anything herein contained to the contrary notwithstanding, the Trustee
shall have full power and authority to receive such money and U.S. Government
Obligations and to apply the same to the purposes for which they were received,
and shall not be affected by any notice to the contrary that may be received by
it within two Business Days prior to such date.

                 The Trustee, subject to the provisions of Article VI of this
Indenture, shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Company (or a trustee or representative on behalf of such
holder) to establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee or representative on behalf of any such holder or
holders.  In the event that the Trustee determines in good faith that further
evidence is required with respect to the right of any Person as a holder of
such Senior Indebtedness to participate in any payment or distribution pursuant
to this Article XV, the Trustee may request such Person to furnish evidence to
the reasonable satisfaction of the Trustee as to the amount of such Senior
Indebtedness held by such Person, the extent to which such Person is entitled
to participate in such payment or distribution and any other facts pertinent to
the rights of such Person under this Article XV, and, if such evidence is not
furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

                 Upon any payment or distribution of assets of the Company
referred to in this Article XV, the Trustee and the Securityholders shall be
entitled to rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding up or similar case or proceeding is
pending, or a certificate of the trustee in bankruptcy, liquidating trustee,
custodian, receiver, assignee for the benefit of creditors, agent or other
person making such payment or distribution, delivered to the Trustee or to the
Securityholders, for the purpose of ascertaining the persons entitled to
participate in such payment or distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article XV.

                 SECTION 15.07    Rights of the Trustee; Holders of Senior
                                  Indebtedness.

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

                 With respect to the holders of Senior Indebtedness of the
Company, the Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this Article XV, and
no implied covenants or obligations





                                       77
<PAGE>   86

with respect to the holders of such Senior Indebtedness shall be read into this
Indenture against the Trustee.  The Trustee shall not be deemed to owe any
fiduciary duty to the holders of such Senior Indebtedness and, subject to the
provisions of Article VI of this Indenture, the Trustee shall not be liable to
any holder of Senior Indebtedness if it shall pay over or deliver to
Securityholders, the Company or any other Person money or assets to which any
holder of such Senior Indebtedness shall be entitled by virtue of this Article
XV or otherwise.

                 Nothing in this Article XV shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 6.06.

                 SECTION 15.08    Subordination May Not Be Impaired.

                 No right of any present or future holder of any Senior
Indebtedness of the Company to enforce subordination as herein provided shall
at any time in any way be prejudiced or impaired by any act or failure to act
on the part of the Company or by any act or failure to act, in good faith, by
any such holder, or by any noncompliance by the Company with the terms,
provisions and covenants of this Indenture, regardless of any knowledge thereof
that any such holder may have or otherwise be charged with.

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

                                  ARTICLE XVI

                      EXTENSION OF INTEREST PAYMENT PERIOD

                 SECTION 16.01    Extension of Interest Payment Period.

                 So long as no Event of Default has occurred and is continuing,
the Company shall have the right, at any time and from time to time during the
term of the Securities, to defer payments of interest by extending the interest
payment period of such Securities for a period not exceeding 10 consecutive
semi-annual periods, including the first such semi-annual period during such
extension period (the "Extended Interest Payment Period"), during which
Extended Interest Payment Period no interest shall be due and payable; provided
that no Extended Interest Payment Period shall end on a date other than an
Interest Payment Date or extend beyond the Maturity Date.  To the extent
permitted by applicable law, interest, the payment of which has been deferred
because of the extension of the interest payment period pursuant to this
Section 16.01, will bear interest thereon at the Coupon Rate compounded
semi-annually for each semi-annual period of the Extended Interest Payment
Period ("Compounded Interest").  At the end of the Extended Interest Payment
Period, the Company shall pay all interest accrued and unpaid on the
Securities, including any Additional Sums and Compounded Interest (together,
"Deferred Interest") that shall be payable to the holders of the Securities in
whose names the Securities are registered in the Security Register on the first
record date preceding the end of the Extended Interest Payment Period.  Before
the termination of any Extended Interest Payment Period, the Company may
further defer payments of interest by further extending such period, provided
that such period, together with all such previous and further extensions within
such Extended Interest Payment Period, shall not exceed 10 consecutive
semi-annual periods, including the first such semi-annual period during such
Extended Interest Payment Period, end on a date other than an Interest Payment
Date or extend beyond the Maturity Date.  Upon the termination of any Extended
Interest Payment Period and the payment of all Deferred Interest then due, the
Company may commence a new Extended Interest Payment Period, subject to the
foregoing requirements.  No interest shall be due and payable during an
Extended Interest Payment Period, except at the end thereof, but the Company
may prepay at any time all or any portion of the interest accrued during an
Extended Interest Payment Period.

                 SECTION 16.02    Notice of Extension.

                 (a)  If the Property Trustee is the only registered holder of
the Securities at the time the Company selects an Extended Interest Payment
Period, the Company shall give written notice to the Administrative Trustees,
the Property Trustee and





                                       79
<PAGE>   88

the Trustee of its selection of such Extended Interest Payment Period five
Business Days before the earlier of (i) the next succeeding date on which
Distributions on the Trust Securities issued by AMCORE Capital Trust are
payable, or (ii) the date AMCORE Capital Trust is required to give notice of
the record date, or the date such Distributions are payable, to any national
securities exchange or to holders of the Capital Securities issued by AMCORE
Capital Trust, but in any event at least five Business Days before such record
date.

                 (b)  If the Property Trustee is not the only holder of the
Securities at the time the Company selects an Extended Interest Payment Period,
the Company shall give the holders of the Securities and the Trustee written
notice of its selection of such Extended Interest Payment Period at least 10
Business Days before the earlier of (i) the next succeeding Interest Payment
Date, or (ii) the date the Company is required to give notice of the record or
payment date of such interest payment to any national securities exchange.

                 (c)  The semi-annual period in which any notice is given
pursuant to paragraphs (a) or (b) of this Section 16.02 shall be counted as one
of the 10 semi-annual periods permitted in the maximum Extended Interest
Payment Period permitted under Section 16.01.

                             AMCORE FINANCIAL, INC.

        Series A 9.35% JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE
                               DUE JUNE 15, 2027

                 AMCORE Financial, Inc., a Nevada corporation (the "Company",
which term includes any successor Person under the Indenture hereinafter
referred to), for value received, hereby promises to pay to The First National
Bank of Chicago, as Property Trustee, on behalf of AMCORE Capital Trust I or
registered assigns, the principal sum of _____________ Dollars on June 15, 2027
(the "Maturity Date"), unless previously redeemed, and to pay interest on the
outstanding principal amount hereof from March 25, 1997, or from the most
recent interest payment date (each such date, an "Interest Payment Date") to
which interest has been paid or duly provided for, semi-annually (subject to
deferral as set forth herein) in arrears on June 15 and December 15 of each
year, commencing June 15, 1997 at the rate of 9.35% per annum until the
principal hereof shall have become due and payable, and on any overdue
principal and premium, if any, and (without duplication and to the extent that
payment of such interest is enforceable under applicable law) on any overdue
installment of interest at the same rate per annum compounded semi-annually.
The amount of interest payable on any Interest Payment Date shall be computed
on the basis of a 360-day year of twelve 30-day months and, for any period less
than a full calendar month, the number of days elapsed in such month.  In the
event that any date on which the principal of (or premium, if any) or interest
on this Security is payable is not a Business Day, then the payment 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 next succeeding Business Day falls in the next calendar year, then
such payment shall be made on the immediately preceding Business Day, in each
case with the same force and effect as if made on such date.  Pursuant to the
Indenture, in certain circumstances the Company will be required to pay
Additional Sums and Compounded Interest (each as defined in the Indenture) with
respect to this Security.  Pursuant to the Registration Rights Agreement, in
certain limited circumstances the Company will be required to pay Liquidated
Damages (as defined in the Registration Rights Agreement) with respect to this
Security.

                 The interest installment so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities, as defined in said Indenture) is registered at the
close of business on the regular record date for such interest installment,
which shall be at the close of business on the 15th day of the month
immediately





                                      A-3
<PAGE>   93

preceding the month in which the relevant interest payment date falls.  Any
such interest installment not punctually paid or duly provided for shall
forthwith cease to be payable to the holders on such regular record date and
may be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on a special
record date to be fixed by the Trustee for the payment of such defaulted
interest, notice whereof shall be given to the holders of Securities not less
than 10 days prior to such special record date, or may be paid at any time in
any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such notice
as may be required by such exchange, all as more fully provided in the
Indenture.

                 The principal of (and premium, if any) and interest on this
Security shall be payable at the office or agency of the Trustee maintained for
that purpose in any coin or currency of the United States of America that at
the time of payment is legal tender for payment of public and private debts;
provided, however, that, payment of interest may be made at the option of the
Company by (i) check mailed to the holder at such address as shall appear in
the Security Register or (ii) by transfer to an account maintained by the
Person entitled thereto, provided that proper written transfer instructions
have been received by the relevant record date.  Notwithstanding the foregoing,
so long as the holder of this Security is the Property Trustee, the payment of
the principal of (and premium, if any) and interest on this Security will be
made at such place and to such account as may be designated by the Property
Trustee.

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

                 This Security shall not be entitled to any benefit under the
Indenture hereinafter referred to, or be valid or become obligatory for any
purpose until the Certificate of

be duly executed.

                         (FORM OF REVERSE OF SECURITY)

                 This Security is one of the Securities of the Company (herein
sometimes referred to as the "Securities"), specified in the Indenture, all
issued or to be issued under and pursuant to an Indenture, dated as of March
25, 1997 (the "Indenture"), duly executed and delivered between the Company and
The First National Bank of Chicago, as Trustee (the "Trustee"), to which
Indenture reference is hereby made for a description of the rights, limitations
of rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the holders of the Securities.

                 Upon the occurrence and continuation of a Special Event prior
to March 1, 2007 (the "Initial Optional Redemption Date"), the Company shall
have the right, at any time within 90 days following the occurrence of such
Special Event, to redeem this Security in whole (but not in part) at the
Special Event Redemption Price.  "Special Event Redemption Price" shall mean,
with respect to any redemption of the Securities following a Special Event, an
amount in cash equal to the greater of (i) 100% of the principal amount to be
redeemed or (ii) the sum, as determined by a Quotation Agent, of the present
values of the principal amount and premium payable with respect to an Optional
Redemption (as defined below) on the Initial Optional Redemption Date, together
with scheduled payments of interest on the Securities from the redemption date
to and including the Initial Optional Redemption Date, discounted to the
redemption date on a semi-annual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Adjusted Treasury Rate, plus, in each case, any
accrued and unpaid interest thereon, including Compounded Interest and
Additional Sums, if any, to the date of such redemption.

                 In addition, the Company shall have the right to redeem this
Security, in whole or in part, at any time on or after the Initial Optional
Redemption Date (an "Optional Redemption"), at the redemption prices set forth
below (expressed as percentages of principal to be redeemed) plus accrued and
unpaid interest thereon (including Additional Sums and Compounded Interest, if
any) to the applicable date of redemption (the "Optional Redemption Price") if
redeemed during the 12-month period beginning March 1 of the years indicated
below.

               2017 and thereafter                          100.0000%

                 The Optional Redemption Price or the Special Event Redemption
Price, as the case requires, shall be paid prior to 12:00 noon, New York time,
on the date of such redemption or at such earlier time as the Company
determines, provided, that the Company shall deposit with the Trustee an amount
sufficient to pay the applicable Redemption Price by 10:00 a.m., New York time,
on the date such Redemption Price is to be paid.  Any redemption pursuant to
this paragraph will be made upon not less than 30 days nor more than 60 days'
notice.  If the Securities are only partially redeemed by the Company pursuant
to an Optional Redemption, the particular Securities to be redeemed shall be
selected on a pro rata basis, or by lot or by any other method utilized by the
Trustee, not more than 60 days prior to the date fixed for redemption from the
outstanding Securities not previously called for redemption, provided, however,
that if at the time of redemption, the Securities are registered as a Global
Security, the Depositary shall determine, in accordance with its procedures,
the principal amount of such Securities held for the account of its
participants to be redeemed.

                 In the event of redemption of this Security in part only, a
new Security or Securities for the unredeemed portion hereof will be issued in
the name of the holder hereof upon the cancellation hereof.

                 Notwithstanding the foregoing, any redemption of Securities by
the Company shall be subject to the prior approval of the Board of Governors of
the Federal Reserve System (the "Federal Reserve"), if such approval is then
required under applicable capital guidelines or policies of the Federal
Reserve.

                 In case an Event of Default, as defined in the Indenture,
shall have occurred and be continuing, the principal of all of the Securities
may be declared, and upon such declaration shall become, due and payable, in
the manner, with the effect and subject to the conditions provided in the
Indenture.

                 The Indenture contains provisions permitting the Company and
the Trustee, with the consent of the holders of a majority in aggregate
principal amount of the Securities at the time outstanding, as defined in the
Indenture, to execute supplemental indentures for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of modifying in any manner the rights of the holders of the
Securities; provided, however, that no such supplemental indenture shall,
without the consent of each holder of Securities then outstanding and affected
thereby, (i) extend the Maturity Date of any Securities, or reduce the
principal amount thereof, or reduce any amount payable on redemption





                                      A-8
<PAGE>   98

thereof, or reduce the rate or extend the time of payment of interest thereon
(subject to Article XVI of the Indenture), or make the principal of, or
interest or premium on, the Securities payable in any coin or currency other
than U.S. dollars, or impair or affect the right of any holder of Securities to
institute suit for the payment thereof, or (ii) reduce the aforesaid percentage
of Securities, the holders of which are required to consent to any such
supplemental indenture.  The Indenture also contains provisions permitting the
holders of a majority in aggregate principal amount of the Securities at the
time outstanding affected thereby, on behalf of all of the holders of the
Securities, to waive any past default in the performance of any of the
covenants contained in the Indenture, or established pursuant to the Indenture,
and its consequences, except a default in the payment of the principal of or
premium, if any, or interest on any of the Securities or a default in respect
of any covenant or provision under which the Indenture cannot be modified or
amended without the consent of each holder of Securities then outstanding.  Any
such consent or waiver by the holder of this Security (unless revoked as
provided in the Indenture) shall be conclusive and binding upon such holder and
upon all future holders and owners of this Security and of any Security issued
in exchange hereof or in place hereof (whether by registration of transfer or
otherwise), irrespective of whether or not any notation of such consent or
waiver is made upon this Security.

                 No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Security at the time and place and at the
rate and in the money herein prescribed.

                 So long as no Event of Default shall have occurred and be
continuing, the Company shall have the right, at any time and from time to time
during the term of the Securities, to defer payments of interest by extending
the interest payment period of such Securities for a period not exceeding 10
consecutive semi-annual periods, including the first such semi-annual period
during such extension period, and not extending beyond the Maturity Date of the
Securities (an "Extended Interest Payment Period"), at the end of which period
the Company shall pay all interest then accrued and unpaid (together with
interest thereon at the rate specified for the Securities to the extent that
payment of such interest is enforceable under applicable law).  Before the
termination of any such Extended Interest Payment Period, the Company may
further defer payments of interest by further extending such Extended Interest
Payment Period, provided that such Extended Interest Payment Period, together
with all such previous and further extensions within such Extended Interest
Payment Period, (i) shall not exceed 10 consecutive semi-annual periods,
including the first semi-annual period during





                                      A-9
<PAGE>   99

such Extended Interest Payment Period, (ii) shall not end on any date other
than an Interest Payment Date and (iii) shall not extend beyond the Maturity
Date of the Securities.  Upon the termination of any such Extended Interest
Payment Period and the payment of all accrued and unpaid interest and any
additional amounts then due, the Company may commence a new Extended Interest
Payment Period, subject to the foregoing requirements.

                 The Company has agreed that it will not (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Company's capital stock (which
includes common and preferred stock) (other than (a) dividends or distributions
in shares of, or options, warrants or rights to subscribe for or purchase
shares of, Common Stock of the Company, (b) any declaration of a dividend in
connection with the implementation of a stockholder's rights plan, or the
issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto, (c) as a result of a
reclassification of the Company's capital stock or the exchange or the
conversion of one class or series of the Company's capital stock, for another
class or series of the Company's capital stock, (d) the purchase of fractional
interests in shares of the Company's capital stock pursuant to the exchange or
conversion of such capital stock or the security being exchanged or converted,
(e) purchases of Common Stock related to the issuance of Common Stock or rights
under any of the Company's benefit plans for its directors, officers or
employees or any of the Company's dividend reinvestment plans, and (f)
purchases of Common Stock in connection with the satisfaction by the Company of
its obligations pursuant to any contract or security requiring the Company to
purchase shares of Common Stock) or (ii) make any payment of principal,
interest or premium, if any, on or repay or repurchase or redeem any debt
securities of the Company that rank pari passu with or junior in right of
payment to the Securities or (iii) make any guarantee payments with respect to
any guarantee (other than payments under the Capital Securities Guarantee) by
the Company of the debt securities of any Subsidiary of the Company if such
guarantee ranks pari passu or junior in right of payment to the Securities if
at such time (1) an Event of Default shall have occurred and be continuing, (2)
there shall have occurred any event of which the Company has actual knowledge
that (x) is or, with the giving of notice or the lapse of time, or both, would
be, an Event of Default and (y) in respect of which the Company shall not have
taken reasonable steps to cure, (3) if the Securities are held by AMCORE
Capital Trust, the Company shall be in default with respect to its payment
obligations under the Capital Securities Guarantee or (4) the Company shall
have given notice of its election of the exercise of its right to extend the
interest payment period and any such extension shall be continuing.

                 Subject to (i) the prior approval of the Federal Reserve if
such approval is then required under applicable capital guidelines or policies
of the Federal Reserve and (ii) the receipt by the Company of an opinion of
counsel to the effect that such distribution will not be a taxable event to
holders of Capital Securities, the Company will have the right at any time to
liquidate the AMCORE Capital Trust and cause the Securities to be distributed
to the holders of the Trust Securities in liquidation of the Trust.

                 The Securities are issuable only in registered form without
coupons in denominations of $1,000.00 and any integral multiple thereof.  As
provided in the Indenture and subject to the transfer restrictions limitations
as may be contained herein and therein from time to time, this Security is

surrender of this Security for registration of transfer at the office or agency
of the Company in the City and State of New York accompanied by a written
instrument or instruments of transfer in form satisfactory to the Company and
the Security Registrar duly executed by the holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of authorized
denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service charge will be
made for any such registration of transfer, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge payable in
relation thereto.

                 Prior to due presentment for registration of transfer of this
Security, the Company, the Trustee, any authenticating agent, any paying agent,
any transfer agent and the registrar may deem and treat the holder hereof as

notwithstanding any notice of ownership or writing hereon made by anyone other
than the Security Registrar) for the purpose of receiving payment of or on
account of the principal hereof and premium, if any, and (subject to the
Indenture) interest due hereon and for all other purposes, and neither the
Company nor the Trustee nor any authenticating agent nor any paying agent nor
any transfer agent nor any registrar shall be affected by any notice to the
contrary.

                 No recourse shall be had for the payment of the principal of
or premium, if any, or interest on this Security, or for any claim based
hereon, or otherwise in respect hereof, or based on or in respect of the
Indenture, against any incorporator, stockholder, officer or director, past,
present or future, as such, of the Company or of any predecessor or successor
Person, whether by virtue of any constitution, statute or rule of law, or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the

consideration for the issuance hereof, expressly waived and released.

                 All terms used in this Security that are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD
TO CONFLICT OF LAW PROVISIONS THEREOF.

                              DECLARATION OF TRUST


     This Declaration of Trust, dated as of March 11, 1997, among AMCORE
Financial, Inc., a Nevada corporation, as "Sponsor," John R. Hecht, The First
National Bank of Chicago and First Chicago Delaware Inc., not in their
individual capacities but solely as "Trustees."  The Sponsor and the Trustees
hereby agree as follows:

     1.  The trust created hereby (the "Trust") shall be known as AMCORE
Capital Trust I  in which name the Trustees, or the Sponsor to the extent
provided herein, may conduct the business of the Trust, make and execute
contracts, and sue and be sued.

     2.  The Sponsor hereby assigns, transfers, conveys and sets over to the
Trust the sum of $10.  The Trustees hereby acknowledge receipt of such amount
in trust from the Sponsor, which amount shall constitute the initial trust
estate.  The Trustees hereby declare that they will hold the trust estate in
trust for the Sponsor.  It is the intention of the parties hereto that the
Trust created hereby constitute a business trust under Chapter 38 of Title 12
of the Delaware Code, 12 Del. C. Section Section 3801 et seq. (the "Business
Trust Act"), and that this document constitutes the governing instrument of the
Trust.  The Trustees are hereby authorized and directed to execute and file a
certificate of trust with the Delaware Secretary of State in accordance with
the provisions of the Business Trust Act.

     3.  The Sponsor and the Trustees will enter into an amended and restated
Declaration of Trust, satisfactory to each such party, to provide for the
contemplated operation of the Trust created hereby and the issuance of the
Capital Securities and Common Securities referred to therein.  Prior to the
execution and delivery of such amended and restated Declaration of Trust, the
Trustees shall not have any duty or obligation hereunder or with respect to the
trust estate, except as otherwise required by applicable law or as may be
necessary to obtain prior to such execution and delivery of any licenses,
consents or approvals required by applicable law or otherwise.

     4.  The Sponsor and the Trustees hereby authorize and direct the Sponsor,
as the sponsor of the Trust, (i) to execute, if necessary, an offering
memorandum (the "Offering Memorandum") in preliminary and final form    
prepared by the Sponsor, in relation to the offering and sale of Capital
Securities 


<PAGE>   2



to the initial purchasers named in the Offering Memorandum and the resell of
such Capital Securities (a) to qualified institutional buyers in reliance on
Rule 144A under the Securities Act of 1933, as amended (the "Securities Act")
or (b) to institutional "accredited investors" (as defined in   Rule 501(a)
(1), (2), (3) or (7) under the Securities Act; (ii) to execute and file an
application, prepared by the Sponsor, to permit the Capital Securities to be
quoted on the Private Offerings, Resales and Trading through Automated Linkages
System ("PORTAL");  (iii) to execute and file an application on behalf of the
Trust with the Depository Trust Company; (iv) to file and execute on behalf of
the Trust such applications, reports, surety bonds, irrevocable consents,
appointments of attorney for service of process and other papers and documents
as shall be necessary or desirable to register the Capital Securities under the
state securities or "Blue Sky" laws and (v) to execute on behalf of the Trust
one or more purchase agreements with one or more initial purchasers relating to
the offering of the Capital Securities.  In the event that any filing referred
to in clauses (i) through (iv) above is required by the rules and regulations
of state securities or Blue Sky laws, to be executed on behalf of the Trust by
the Trustees, in their capacities as Trustees of the Trust, then the Trustees
are hereby authorized and directed to join in any such filing and to execute on
behalf of the Trust any and all of the foregoing, it being understood that each
of The First National Bank of Chicago and  First Chicago Delaware Inc., in its
capacity as Trustee of the Trust, shall not be required to join in any such
filing or execute on behalf of the Trust any such document unless required by
the rules and regulations of state securities or Blue Sky laws.  In connection
with all of the foregoing, the Sponsor and each Trustee, solely in its capacity
as Trustee of the Trust, hereby constitutes and appoints John R. Hecht, Kenneth
Edge and Greg Sprawka each of them, as his or its, as the case may be, true and
lawful attorneys-in-fact and agents, with full power of substitution, for the
Sponsor or in the Sponsor's name, place and stead, in any and all capacities,
granting unto said attorneys-in-fact and agents full power and authority to do
and perform each and every act and thing requisite and necessary to be done in
connection therewith, as fully to all intents and purposes as the Sponsor might
or could do in person, hereby ratifying and confirming all that said
attorneys-in-fact and agents or any of them, or their respective substitute or
substitutes, shall do or cause to be done by virtue hereof.

     5.  This Declaration of Trust may be executed in one or more
counterparts.

     6.  The number of Trustees initially shall be three (3) and thereafter
the number of Trustees shall be such number as shall be fixed from time to 



                                      2

time by a written instrument signed by the Sponsor which may increase or
decrease the number of Trustees; provided, however, that to the extent required
by the Business Trust Act, one Trustee shall either be a natural person who is
a resident of the State of Delaware or, if not a natural person, an entity
which has its principal place of business in the State of Delaware and
otherwise meets the requirements of applicable Delaware law.  Subject to the    
foregoing, the Sponsor is entitled to appoint or remove without cause any
Trustee at any time.  A Trustee may resign upon 30 days' prior notice to the
Sponsor.

     7.  First Chicago Delaware Inc., in its capacity as Trustee, shall not
have the powers or the duties of the Trustees set forth herein (except as may
be required under the Business Trust Act) and shall be a Trustee hereunder for
the sole and limited purpose of fulfilling the requirements of Section  3807 of
the Business Trust Act.

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

Securities and its consequences, provided that, if the underlying Event of

Default under the Declaration shall also not be waivable; or





                                      11
<PAGE>   18

                 (ii)       requires the consent or vote of greater than a
         majority in aggregate principal amount of the holders of the

         represents of the aggregate principal amount of the Debentures
         outstanding.

shall extend to any subsequent or other default or an Event of Default with

waiver by the Holders of the Capital Securities of an Event of Default with

any further act, vote, or consent of the Holders of the Common Securities.

                 The Holders of a Majority in liquidation amount of the Capital
Securities shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Property Trustee or

remedies available to it as holder of the Debentures; provided, however, that
(subject to the provisions of Section 3.9) the Property Trustee shall have the
right to decline to follow any such direction if the Property Trustee shall
determine that the action so directed would be unjustly prejudicial to the
Holders not taking part in such direction or if the Property Trustee, being
advised by counsel, determines that the action or proceeding so directed may
not lawfully be taken or if the Property Trustee, in good faith, by its board
of directors or trustees, executive committee, or a trust committee of
directors or trustees and/or Responsible Officers, shall determine that the
action or proceedings so directed would involve the Property Trustee in
personal liability.


                 (b)        The Holders of a Majority in liquidation amount of
the Common Securities may, by vote, on behalf of the Holders of all of the
Common Securities, waive any past Event of Default

the underlying Event of Default under the Indenture:

                 (i)        is not waivable under the Indenture, except where
         the Holders of the Common Securities are deemed to have waived such
         Event of Default under the Declaration as provided below in this
         Section 2.6(b), the Event of Default under the Declaration shall also
         not be waivable; or

                 (ii)       requires the consent or vote of a Super Majority to
         be waived, except where the Holders of the Common Securities are
         deemed to have waived such Event of Default under the Declaration as
         provided below in this Section 2.6(b), the Event of Default under the
         Declaration may only be waived by the vote of the Holders of at least
         the proportion in aggregate liquidation amount of the Common
         Securities that the relevant Super Majority represents of the
         aggregate principal amount of the Debentures outstanding;

provided further, the Holders of Common Securities will be deemed to have
waived any such Event of Default and all Events of Default with respect to the
Common Securities and their consequences if all Events of Default with respect
to the Capital Securities have been cured, waived or otherwise eliminated, and
until such Events of Default have been so cured, waived or otherwise
eliminated, the Property Trustee will be deemed to be acting solely on behalf
of the Holders of the Capital Securities and only the Holders of the Capital
Securities will have the right to direct the Property Trustee in accordance
with the terms of the Securities.  The foregoing provisions of this Section
2.6(b) shall be in lieu of Section 316(a)(1)(A) and 316(a)(1)(B) of
the Trust Indenture Act and such Section 316(a)(1)(A) and 316(a)(1)(B)
of the Trust Indenture Act are hereby expressly excluded from this Declaration
and the Securities, as permitted by the Trust Indenture Act.  Subject to the
foregoing provisions of this Section 2.6(b), upon such waiver, any such default
shall cease to exist and any Event of Default with respect to the Common
Securities arising therefrom shall be deemed to have been cured for every
purpose of this Declaration, but no such waiver shall extend to any subsequent
or other default or Event of Default with respect to the Common Securities or
impair any right consequent thereon.

                 (c)        A waiver of an Event of Default under the Indenture
by the Property Trustee, at the direction of the Holders of the Capital
Securities, constitutes a waiver of the corresponding Event of Default under
this Declaration.  The foregoing provisions of this Section 2.6(c) shall be in
lieu of Section  316(a)(1)(B) of the Trust Indenture Act and such Section
316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this
Declaration and the Securities, as permitted by the Trust Indenture Act.

by mail, first class postage prepaid, to the Holders, notices of all defaults
with respect to the Securities actually known to a Responsible Officer, unless
such defaults have been cured before the giving of such notice (the term
"defaults" for the purposes of this Section 2.7(a) being hereby defined to be
an Event of Default as defined in the Indenture,  shall not include any periods
of grace provided for therein and irrespective of the giving of any notice

principal of (or premium, if any) or interest on any of the Debentures, the
Property Trustee shall be protected in withholding such notice if and so long
as a Responsible Officer in good faith determines that the withholding of such
notice is in the interests of the Holders.

                 (b)        The Property Trustee shall not be deemed to have
knowledge of any default except:

         Indenture; or

the Property Trustee on behalf of the Trust in accordance with its powers shall
constitute the act of and serve to bind the Trust.  In dealing with the
Trustees acting on behalf of the Trust, no Person shall be required to inquire
into the authority of the Trustees to bind the Trust.  Persons dealing with the
Trust are entitled to rely conclusively on the power and authority of the
Trustees as set forth in this Declaration.

SECTION 3.5      Title to Property of the Trust.

Trust.  The Holders shall not have legal title to any part of the assets of the
Trust, but shall have an undivided beneficial interest in the assets of the
Trust.

                 (l)        to act as, or appoint another Person to act as,

                 The Administrative Trustees must exercise the powers set forth
in this Section 3.6 in a manner that is consistent with the purposes and
functions of the Trust set out in Section 3.3, and the Administrative Trustees
shall not take any action that is inconsistent with the purposes and functions
of the Trust set forth in Section 3.3.

                 Subject to this Section 3.6, the Administrative Trustees shall
have none of the powers or the authority of the Property Trustee set forth in
Section 3.8.

                 Any expenses incurred by the Administrative Trustees pursuant
to this Section 3.6 shall be reimbursed by the Debenture Issuer.

SECTION 3.7      Prohibition of Actions by the Trust and the Trustees.

                 (a)        The Trust shall not, and the Trustees (including
the Property Trustee and the Delaware Trustee), in exercising their respective
rights and performing their respective duties hereunder, shall not engage in
any activity other than as required or authorized by this Declaration.  The
Trust shall not:

                 (i)        invest any proceeds received by the Trust from
         holding the Debentures, but shall distribute all such proceeds to
         Holders pursuant to the terms of this Declaration and of the
         Securities;

                 (ii)       acquire any assets other than as expressly provided
         herein;

                 (iii)      possess Trust property for other than a Trust
         purpose;

                 (iv)       make any loans or incur any indebtedness other than
         loans represented by the Debentures;

                 (v)        possess any power or otherwise act in such a way as
         to vary the Trust assets or the terms of the Securities in any way
         whatsoever except as otherwise expressly provided herein;

                 (vi)       issue any securities or other evidences of
         beneficial ownership of, or beneficial interest in, the Trust other
         than the Securities;

                 (vii)      other than as provided in this Declaration or Annex
         I, (A) direct the time, method and place of conducting any proceeding
         with respect to any remedy available to the Debenture Trustee, or
         exercising any trust or power conferred upon the Debenture Trustee
         with respect to the Deben-





                                      19
<PAGE>   26

         tures, (B) waive any past default that is waivable under the
         Indenture, or (C) exercise any right to rescind or annul any
         declaration that the principal of all the Debentures shall be due and
         payable; or

                 (viii) consent to any amendment, modification or termination
         of the Indenture or the Debentures where such consent shall be
         required unless the Trust shall have received an opinion of a
         nationally recognized independent tax counsel experienced in such
         matters to the effect that such amendment, modification or termination
         will not cause more than an insubstantial risk that for United States
         federal income tax purposes the Trust will not be classified as a
         grantor trust.

SECTION 3.8      Powers and Duties of the Property Trustee.

                 (a)        The legal title to the Debentures shall be owned by
and held of record in the name of the Property Trustee in trust for the benefit
of the Holders.  The right, title and interest of the Property Trustee to the
Debentures shall vest automatically in each Person who may hereafter be
appointed as Property Trustee in accordance with Section 5.7.  Such vesting and
cessation of title shall be effective whether or not conveyancing documents
with regard to the Debentures have been executed and delivered.

                 (b)        The Property Trustee shall not transfer its right,
title and interest in the Debentures to the Administrative Trustees or to the
Delaware Trustee (if the Property Trustee does not also act as Delaware
Trustee).

                 (c)        The Property Trustee shall:

                 (i)        establish and maintain a segregated non-interest
         bearing trust account (the "Property Trustee Account") in the name of
         and under the exclusive control of the Property Trustee on behalf of
         the Holders and, upon the receipt of payments of funds made in respect
         of the Debentures held by the Property Trustee, deposit such funds
         into the Property Trustee Account and make payments or cause the
         Paying Agent to make payments to the Holders from the Property Trustee
         Account in accordance with Section 6.1.  Funds in the Prop- erty
         Trustee Account shall be held uninvested until disbursed in accordance
         with this Declaration.  The Property Trustee Account shall be an
         account that is maintained with a banking institution the rating on
         whose long-term unsecured indebtedness is [at least equal to the
         rating assigned to the Capital Securities by a "nationally recognized
         statistical rating organization", as that term is defined for purposes
         of Rule 436(g)(2) under the Securities Act];

                 (ii)       engage in such ministerial activities as shall be
         necessary or appropriate to effect the redemption of the Securities to
         the extent the Debentures are redeemed or mature; and

                 (iii)      upon written notice of distribution issued by the
         Administrative Trustees in accordance with the terms of the
         Securities, engage in such ministerial activities as shall be
         necessary or appropriate to effect the distribution of the Debentures
         to Holders upon the occurrence of certain events.

                 (d)        The Property Trustee shall take all actions and
perform such duties as may be specifically required of the Property Trustee
pursuant to the terms of the Securities.

                 (e)        Subject to Section 3.9(a), the Property Trustee may
take any Legal Action which arises out of or in connection with an Event of
Default of which a Responsible Officer has actual knowledge or the Property
Trustee's duties and obligations under this Declaration or the Trust Indenture
Act and if the Property Trustee shall have failed to take such Legal Action, to
the fullest extent permitted by law, the Holders of the Capital Securities may
take such Legal Action, to the same extent as if such Holders of Capital
Securities held an aggregate principal amount of Debentures equal to the
aggregate liquidation amount of such Capital Securities, without first
proceeding against the Property Trustee or the Trust; provided, however, that
if an Event of Default has occurred and is continuing and such event is
attributable to the failure of the Debenture Issuer to pay the principal of or
premium, if any, or interest on the Debentures on the date such principal,
premium, if any, or interest is otherwise payable (or in the case of
redemption, on the redemption date), then a Holder of Capital Securities may
directly institute a proceeding for enforcement of payment to such Holder of
the principal of or premium, if any, or interest on the Debentures having a
principal amount equal to the aggregate liquidation amount of the Capital
Securities of such Holder (a "Direct Action") on or after the respective due
date specified in the Debentures.  In connection with such Direct Action, the
rights of the Holders of the Common Securities will be subrogated to the rights
of such Holder of Capital Securities to the extent of any payment made by the
Debenture Issuer to such Holder of Capital Securities in such Direct Action.
Except as provided in the preceding sentences, the Holders of Capital
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures.

                 (f)        The Property Trustee shall continue to serve as a
Trustee until either:





                                      21
<PAGE>   28

                 (i)        the Trust has been completely liquidated and the
         proceeds of the liquidation distributed to the Holders pursuant to the
         terms of the Securities; or

                 (ii)       a successor Property Trustee has been appointed and
         has accepted that appointment in accordance with Section 5.7 (a
         "Successor Property Trustee").

                 (g)        The Property Trustee shall have the legal power to
exercise all of the rights, powers and privileges of a holder of Debentures
under the Indenture and, if an Event of Default actually known to a Responsible
Officer occurs and is continuing, the Property Trustee may, for the benefit of
Holders, enforce its rights as holder of the Debentures subject to the rights
of the Holders pursuant to the terms of such Securities.

                 (h)        The Property Trustee shall be authorized to
undertake any actions set forth in Section  317(a) of the Trust Indenture Act.

                 (i)        For such time as the Property Trustee is the Paying
Agent, the Property Trustee may authorize one or more Persons to act as
additional Paying Agents and to pay Distributions, redemption payments or
liquidation payments on behalf of the Trust with respect to all Securities and
any such Paying Agent shall comply with Section  317(b) of the Trust Indenture
Act.  Any such additional Paying Agent may be removed by the Property Trustee
at any time the Property Trustee remains as Paying Agent and a successor Paying
Agent or additional Paying Agents may be (but are not required to be) appointed
at any time by the Property Trustee while the Property Trustee is so acting as
Paying Agent.

                 (j)        Subject to this Section 3.8, the Property Trustee
shall have none of the duties, liabilities, powers or the authority of the
Administrative Trustees set forth in Section 3.6.

                 Notwithstanding anything expressed or implied to the contrary
in this Declaration or any Annex or Exhibit hereto, (i) the Property Trustee
must exercise the powers set forth in this Section 3.8 in a manner that is
consistent with the purposes and functions of the Trust set out in Section 3.3,
and (ii) the Property Trustee shall not take any action that is inconsistent
with the purposes and functions of the Trust set out in Section 3.3.

SECTION 3.9      Certain Duties and Responsibilities of the Property Trustee.

                 (a)        The Property Trustee, before the occurrence of any
Event of Default and after the curing of all Events of Default that may have
occurred, shall undertake to perform only





                                      22
<PAGE>   29

such duties as are specifically set forth in this Declaration and in the
Securities and no implied covenants shall be read into this Declaration against
the Property Trustee.  In case an Event of Default has occurred (that has not
been cured or waived pursuant to Section 2.6) of which a Responsible Officer
has actual knowledge, the Property Trustee shall exercise such of the rights
and powers vested in it by this Declaration, and use the same degree of care
and skill in their exercise, as a prudent person would exercise or use under
the circumstances in the conduct of his or her own affairs.

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

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

                            (A)     the duties and obligations of the Property
                 Trustee shall be determined solely by the express provisions
                 of this Declaration and in the Securities and the Property
                 Trustee shall not be liable except for the performance of such
                 duties and obligations as are specifically set forth in this
                 Declaration and in the Securities, and no implied covenants or
                 obligations shall be read into this Declaration or the
                 Securities against the Property Trustee; and

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

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

                 (iii)      the Property Trustee shall not be liable with
         respect to any action taken or omitted to be taken by it in good faith
         in accordance with the direction of the Holders of not less than a
         Majority in liquidation amount of the





                                      23
<PAGE>   30

         Securities relating to the time, method and place of conducting any
         proceeding for any remedy available to the Property Trustee, or
         exercising any trust or power conferred upon the Property Trustee
         under this Declaration;

                 (iv)       no provision of this Declaration shall require the
         Property Trustee to expend or risk its own funds or otherwise incur
         personal financial liability in the performance of any of its duties
         or in the exercise of any of its rights or powers, if it shall have
         reasonable grounds for believing that the repayment of such funds or
         liability is not reasonably assured to it under the terms of this
         Declaration or indemnity reasonably satisfactory to the Property
         Trustee against such risk or liability is not reasonably assured to
         it;

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

                 (vi)       the Property Trustee shall have no duty or
         liability for or with respect to the value, genuineness, existence or
         sufficiency of the Debentures or the payment of any taxes or
         assessments levied thereon or in connection therewith;

                 (vii)      the Property Trustee shall not be liable for any
         interest on any money received by it except as it may otherwise agree
         in writing with the Sponsor.  Money held by the Property Trustee need
         not be segregated from other funds held by it except in relation to
         the Property Trustee Account maintained by the Property Trustee

         the Property Trustee shall deem it desirable that a matter be proved
         or established before taking, suffering or omitting any action
         hereunder, the Property Trustee (unless other evidence is herein
         specifically prescribed) may, in the absence of bad faith on its part,
         request and conclusively rely upon an Officers' Certificate which,

         indemnity, reasonably satisfactory to the Property Trustee, against
         the costs, expenses (including





                                      25
<PAGE>   32

         reasonable attorneys' fees and expenses and the expenses of the

         that might be incurred by it in complying with such request or
         direction, including such reasonable advances as may be requested by
         the Property Trustee provided, that nothing contained in this Section

                 (ix)       any action taken by the Property Trustee or its
         agents hereunder shall bind the Trust and the Holders, and the
         signature of the Property Trustee or its agents alone shall be
         sufficient and effective to perform any such action and no third party
         shall be required to inquire as to the authority of the Property
         Trustee to so act or as to its compliance with any of the terms and
         provisions of this Declaration, both of which shall be conclusively
         evidenced by the Property Trustee's or its agent's taking such action;

         from the Holders which instructions may only be given by the Holders

         refrain from enforcing such remedy or right or taking such other

         Declaration.

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

SECTION 3.15     Mergers.

                 (a)        The Trust may not merge with or into, consolidate,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, except as described in
Section 3.15(b) and (c).

                 (b)        The Trust may, at the request of the Sponsor, with
the consent of the Administrative Trustees or, if there are more than two, a
majority of the Administrative Trustees and without the consent of the Holders,
the Delaware Trustee or the Property Trustee, merge with or into, consolidate,
amalgamate, or be replaced by, or convey, transfer or lease its properties and
assets as an entirety or substantially as an entirety to, a trust organized as
such under the laws of any State; provided that:

                 (i)        such successor entity (the "Successor Entity")
         either:

                            (A)     expressly assumes all of the obligations of
                 the Trust under the Securities; or

                            (B)     substitutes for the Securities other
                 securities having substantially the same terms as the
                 Securities (the "Successor Securities") so long as the
                 Successor Securities rank the same as the Securities rank with
                 respect to Distributions and payments upon liquidation,
                 redemption and otherwise;

                 (ii)       the Sponsor expressly appoints a trustee of the
         Successor Entity that possesses the same powers and duties as the
         Property Trustee as the holder of the Debentures;

                 (iii)      the Successor Securities are listed, or any
         Successor Securities will be listed upon notification of issuance, on
         any national securities exchange or with another organization on which
         the Capital Securities are then listed or quoted, if any;

                 (iv)       if the Capital Securities (including any Successor
         Securities) are rated by any nationally recognized statistical rating
         organization prior to such transaction, such merger, consolidation,
         amalgamation, replacement, conveyance, transfer or lease does not
         cause the Capital Securities (including any Successor Securities) to
         be downgraded by any nationally recognized statistical rating
         organization;

                 (v)        such merger, consolidation, amalgamation,
         replacement, conveyance, transfer or lease does not adversely affect
         the rights, preferences and privileges of the Holders (including the
         holders of any Successor Securities) in any





                                      28
<PAGE>   35

         material respect (other than with respect to any dilution of such
         Holders' interests in the new entity);

                 (vi)       such Successor Entity has a purpose substantially
         identical to that of the Trust;

                 (vii)      prior to such merger, consolidation, amalgamation,
         replacement, conveyance, transfer or lease, the Sponsor has received
         an opinion of an independent counsel to the Trust 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
                 (including the holders of any Successor Securities) in any
                 material respect (other than with respect to any dilution of
                 the Holders' interest in the new entity); and

                            (B)     following such merger, consolidation,
                 amalgamation, replacement, conveyance, transfer or lease,
                 neither the Trust nor the Successor Entity will be required to
                 register as an Investment Company; and

                 (viii) the Sponsor 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 Capital Securities
         Guarantee and the Common Securities Guarantee.

                 (c)        Notwithstanding Section 3.15(b), the Trust shall
not, except with the consent of Holders of 100% in liquidation amount of the
Securities, consolidate, amalgamate, merge with or into, or be replaced by, or
convey, transfer or lease its properties and assets as an entirety or
substantially as an entirety to, any other Person or permit any other Person to
consolidate, amalgamate, merge with or into, or replace it if such
consolidation, amalgamation, merger, replacement, conveyance, transfer or lease
would cause the Trust or the Successor Entity not to be classified as a grantor
trust for United States federal income tax purposes.

SECTION 4.1      Sponsor's Purchase of Common Securities.

                 At the Closing Time, the Sponsor will purchase all of the
Common Securities then issued by the Trust, in an amount equal to at least 3%
of the total capital of the Trust, at the





                                      29

same time as the Series A Capital Securities are issued and sold.

                 In connection with the issue and sale of the Capital
Securities, the Sponsor shall have the exclusive right and responsibility to
engage in the following activities:

                 (a)        to prepare the Offering Memorandum and to prepare
for filing by the Trust with the Commission any Registration Statement,
including any amendments thereto, as contemplated by the Registration Rights
Agreement;

                 (b)        to determine the States in which to take
appropriate action to qualify or register for sale all or part of the Capital
Securities and to do any and all such acts, other than actions which must be
taken by the Trust, and advise the Trust of actions it must take, and prepare
for execution and filing any documents to be executed and filed by the Trust,
as the Sponsor deems necessary or advisable in order to comply with the
applicable laws of any such States;

                 (c)        if deemed necessary or advisable by the Sponsor, to
prepare for filing by the Trust an application to permit the Capital Securities
to trade or be quoted or listed in or on PORTAL, or any other securities
exchange, quotation system or the Nasdaq Stock Market's National Market;

                 (d)        to prepare for filing by the Trust with the
Commission a registration statement on Form 8-A, including any amendments
thereto, relating to the registration of the Capital Securities under Section
12(b) of the Exchange Act; and

                 (e)        to negotiate the terms of the Purchase Agreement
and the Registration Rights Agreement providing for the sale and registration
of the Capital Securities.

SECTION 4.3      Right to Proceed.

                 The Sponsor acknowledges the rights of the Holders of Capital
Securities, in the event that a failure of the Trust to pay Distributions on
the Capital Securities is attributable to the failure of the Company to pay
interest or principal on the Debentures, to institute a proceeding directly
against the Debenture Issuer for enforcement of its payment obligations on the
Debentures.

                                   TRUSTEES

SECTION 5.1      Number of Trustees: Appointment of Co-Trustee.

                 The number of Trustees initially shall be five (5), and:

                 (a)        at any time before the issuance of any Securities,
the Sponsor may, by written instrument, increase or decrease the number of
Trustees; and

                 (b)        after the issuance of any Securities, the number of
Trustees may be increased or decreased by vote of the Holders of a Majority in
liquidation amount of the Common Securities voting as a class at a meeting of
the Holders of the Common Securities;

provided, however, that, the number of Trustees shall in no event be less than
two (2); provided further that (1) the Delaware Trustee, in the case of a
natural person, shall be a person who is a resident of the State of Delaware or
that, if not a natural person, is an entity which has its principal place of
business in the State of Delaware; (2) there shall be at least one Trustee who
is an employee or officer of, or is affiliated with, the Sponsor (an
"Administrative Trustee"); and (3) one Trustee shall be the Property Trustee
for so long as this Declaration is required to qualify as an indenture under
the Trust Indenture Act, and such Trustee may also serve as Delaware Trustee if
it meets the applicable requirements.  Notwithstanding the above, unless an
Event of Default shall have occurred and be continuing, at any time or times,
for the purpose of meeting the legal requirements of the Trust Indenture Act or
of any jurisdiction in which any part of the Trust's property may at the time
be located, the Holders of a Majority in liquidation amount of the Common
Securities acting as a class at a meeting of the Holders 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 the Trust's 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 this Declaration.  In case an Event of Default has
occurred and is continuing, the Property Trustee alone shall have power to make
any such appointment of a co-trustee.

SECTION 5.2      Delaware Trustee.

                 If required by the Business Trust Act, one Trustee (the

                 (a)        a natural person who is a resident of the State of
Delaware; or

                 (b)        if not a natural person, an entity which has its
principal place of business in the State of Delaware, and otherwise meets the
requirements of applicable law,

provided that, if the Property Trustee has its principal place of business in
the State of Delaware and otherwise meets the requirements of applicable law,
then the Property Trustee shall also be the Delaware Trustee and Section 3.11
shall have no application.

SECTION 5.3      Property Trustee; Eligibility.

                 (a)        There shall at all times be one Trustee (the
"Property Trustee") which shall act as Property Trustee which shall:

                 (i)        not be an Affiliate of the Sponsor; and

                 (ii)       be a corporation organized and doing business under
         the laws of the United States of America or any State or Territory
         thereof or of the District of Columbia, or a corporation or Person
         permitted by the Commission to act as an institutional trustee under
         the Trust Indenture Act, authorized under such laws to exercise
         corporate trust powers, having a combined capital and surplus of at
         least 50 million U.S. dollars ($50,000,000), and subject to
         supervision or examination by Federal, State, Territorial or District
         of Columbia authority.  If such corporation publishes reports of
         condition at least annually, pursuant to law or to the requirements of
         the supervising or examining authority referred to above, then for the
         purposes of this Section 5.3(a)(ii), the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

                 (b)        If at any time the Property Trustee shall cease to
be eligible to so act under Section 5.3(a), the Property Trustee shall
immediately resign in the manner and with the effect set forth in Section
5.7(c).

                 (c)        If the Property Trustee has or shall acquire any
"conflicting interest" within the meaning of Section  310(b) of the Trust
Indenture Act, the Property Trustee and the Holder of the Common Securities (as
if it were the obligor referred to in Section  310(b) of the Trust Indenture
Act) shall in all respects comply with the provisions of Section  310(b) of the
Trust Indenture Act.

age of 21 his or her power for the purposes of signing any documents which the
Administrative

                 (i)        until the issuance of any Securities, by written
         instrument executed by the Sponsor;

                 (ii)       unless an Event of Default shall have occurred and
         be continuing after the issuance of any Securities, by vote of the
         Holders of a Majority in liquidation amount of the Common Securities
         voting as a class at a meeting of the Holders of the Common
         Securities; and

                 (iii)      if an Event of Default shall have occurred and be
         continuing after the issuance of the Securities, with respect to the
         Property Trustee or the Delaware Trustee, by vote of Holders of a
         Majority in liquidation amount of the Capital Securities voting as a

         has accepted such appointment by written instrument executed by such
         Successor Property Trustee and delivered to the Administrative

                 (c)        A Trustee appointed to office shall hold office
until his successor shall have been appointed or until his death, removal or
resignation.  Any Trustee may resign from office (without need for prior or
subsequent accounting) by an instrument in writing signed by the Trustee and
delivered to the Sponsor and the Trust, which resignation shall take effect
upon such delivery or upon such later date as is specified therein; provided,
however, that:

                 (i)        No such resignation of the Trustee that acts as the
         Property Trustee shall be effective:

                            (A)     until a Successor Property Trustee has been
                 appointed and has accepted such appointment by instrument
                 executed by such Successor Property Trustee and delivered to
                 the Trust, the Sponsor and the resigning Property Trustee; or

                            (B)     until the assets of the Trust have been
                 completely liquidated and the proceeds thereof distributed to
                 the Holders; and

                 (ii)       no such resignation of the Trustee that acts as the
         Delaware Trustee shall be effective until a Successor Delaware Trustee
         has been appointed and has accepted such appointment by instrument
         executed by such Successor Delaware Trustee and delivered to the
         Trust, the Sponsor and the resigning Delaware Trustee.

                 (d)        The Holders of the Common Securities or, if an
Event of Default shall have occurred and be continuing after the issuance of
the Securities, the Holders of the Capital Securities shall use their best
efforts to promptly appoint a Successor Delaware Trustee or Successor Property
Trustee, as the case may be, if the Property Trustee or the Delaware Trustee
delivers an instrument of resignation in accordance with this Section 5.7.

                 (e)        If no Successor Property Trustee or Successor
Delaware Trustee shall have been appointed and accepted appointment as provided
in this Section 5.7 within 60 days after delivery of an instrument of
resignation or removal, the Property Trustee or Delaware Trustee resigning or
being removed, as applicable, may petition any court of competent jurisdiction
for appointment of a Successor Property Trustee or Successor Delaware Trustee.
Such court may thereupon, after prescribing such notice, if any, as it may deem
proper and prescribe, appoint a Successor Property Trustee or Successor
Delaware Trustee, as the case may be.

                 (f)        No Property Trustee or Delaware Trustee shall be
liable for the acts or omissions to act of any Successor Property Trustee or
Successor Delaware Trustee, as the case may be.

SECTION 5.8      Vacancies among Trustees.

                 If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 5.1, or if the number of
Trustees is increased pursuant to Section 5.1, a vacancy shall occur.  A
resolution certifying the existence of such vacancy by the Administrative
Trustees or, if there are more than two, a majority of the Administrative
Trustees shall be conclusive evidence of the existence of such vacancy.  The
vacancy shall be filled with a Trustee appointed in accordance with Section
5.7.

SECTION 5.9      Effect of Vacancies.

                 The death, resignation, retirement, removal, bankruptcy,
dissolution, liquidation, incompetence or incapacity to perform the duties of a
Trustee shall not operate to dissolve, terminate or annul the Trust.  Whenever
a vacancy in the number of Administrative Trustees shall occur, until such
vacancy is filled by the appointment of an Administrative Trustee in accordance
with Section 5.7, the Administrative Trustees in office, regardless of their
number, shall have all the powers granted to the Administrative Trustees and
shall discharge all the duties imposed upon the Administrative Trustees by this
Declaration.

SECTION 5.10     Meetings.

                 If there is more than one Administrative Trustee, meetings of
the Administrative Trustees shall be held from time to time upon the call of
any Administrative Trustee.  Regular meetings of the Administrative Trustees
may be held at a time and place fixed by resolution of the Administrative
Trustees.  Notice of any in-person meetings of the Administrative Trustees
shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours before
such meeting.  Notice of any telephonic meetings of the Administrative Trustees
or any committee thereof shall be hand delivered or otherwise delivered in
writing (including by facsimile, with a hard copy by overnight courier) not
less than 24 hours before a meeting.  Notices shall contain a brief statement
of the time, place and anticipated purposes of the meeting.  The presence
(whether in person or by telephone) of an Administrative Trustee at a meeting
shall constitute a waiver of notice of such meeting except where an
Administrative Trustee attends a meeting for the express purpose of objecting
to the transaction of any activity on the ground that the meeting has not been
lawfully called or convened.  Unless provided otherwise in this Declaration,
any action of the Administrative Trustees may be taken at a meeting by vote of
a majority of the Administrative Trustees present (whether in person or by
telephone) and eligible to vote with respect to such matter, provided that a
Quorum is present, or without a meeting by the unanimous written consent of





                                      36
<PAGE>   43

the Administrative Trustees.  In the event there is only one Administrative
Trustee, any and all action of such Administrative Trustee shall be evidenced
by a written consent of such Administrative Trustee.

SECTION 5.11     Delegation of Power.

                 (a)        Any Administrative Trustee may, by power of
attorney consistent with applicable law, delegate to any other natural person
over the age of 21 his or her power for the purpose of executing any documents
contemplated in Section 3.6, including any registration statement or amendment
thereto filed with the Commission, or making any other governmental filing; and

                 (b)        the Administrative Trustees shall have power to
delegate from time to time to such of their number or to officers of the Trust
the doing of such things and the execution of such instruments either in the
name of the Trust or the names of the Administrative Trustees or otherwise as
the Administrative Trustees may deem expedient, to the extent such delegation
is not prohibited by applicable law or contrary to the provisions of the Trust,
as set forth herein.

Section 5.12     Merger, Conversion, Consolidation or Succession to Business.

                 Any Person into which the Property Trustee or the Delaware
Trustee or any Administrative Trustee that is not a natural person, as the case
may be, may be merged or converted or with which it may be consolidated, or any
Person resulting from any merger, conversion or consolidation to which the
Property Trustee or the Delaware Trustee, as the case may be, shall be a party,
or any Person succeeding to all or substantially all the corporate trust
business of the Property Trustee or the Delaware Trustee, as the case may be,
shall be the successor of the Property Trustee or the Delaware Trustee, as the
case may be, hereunder, provided such corporation shall be otherwise qualified
and eligible under this Article, without the execution or filing of any paper
or any further act on the part of any of the parties hereto.

                                DISTRIBUTIONS

SECTION 6.1      Distributions.

                 Holders shall receive Distributions in accordance with the
applicable terms of the relevant Holder's Securities.  If and to the extent
that the Debenture Issuer makes a payment of interest (including Compounded
Interest and Additional Sums (each, as defined in the Indenture)), premium
and/or principal on





                                      37
<PAGE>   44

the Debentures held by the Property Trustee or Liquidated Damages (as defined
in the Registration Rights Agreement) or any other payments pursuant to the
Registration Rights Agreement with respect to the Debentures held by the
Property Trustee (the amount of any such payment being a "Payment Amount"), the
Property Trustee shall and is directed, to the extent funds are available for
that purpose, to make a distribution (a "Distribution") of the Payment Amount
to Holders.

                             ISSUANCE OF SECURITIES

SECTION 7.1      General Provisions Regarding Securities.

                 (a)        The Administrative Trustees shall on behalf of the
Trust issue one class of capital securities representing undivided beneficial
interests in the assets of the Trust having such terms as are set forth in
Annex I (the "Series A Capital Securities") and one class of common securities
representing undivided beneficial interests in the assets of the Trust having
such terms as are set forth in Annex I (the "Common Securities").  The
Administrative Trustees shall on behalf of the Trust issue one class of capital
securities representing undivided beneficial interests in the Trust having such
terms as set forth in Annex I (the "Series B Capital Securities") in exchange
for the Series A Capital Securities accepted for exchange in the Exchange
Offer, which Series B Capital Securities shall not bear the legends required by
Section 9.2(i) unless the Holder of such Series A Capital Securities is either
(A) a broker-dealer who purchased such Series A Capital Securities directly
from the Trust for resale pursuant to Rule 144A or any other available
exemption under the Securities Act, (B) a Person participating in the
distribution of the Series A Capital Securities or (C) a Person who is an
affiliate (as defined in Rule 144A) of the Trust.  The Trust shall issue no
securities or other interests in the assets of the Trust other than the
Securities.

                 (b)        The consideration received by the Trust for the
issuance of the Securities shall constitute a contribution to the capital of
the Trust and shall not constitute a loan to the Trust.

                 (c)        Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable undivided beneficial interests in the assets of
the Trust.

                 (d)        Every Person, by virtue of having become a Holder
or a Capital Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly





                                      38
<PAGE>   45

assented and agreed to the terms of, and shall be bound by, this Declaration.

SECTION 7.2      Execution and Authentication.

                 (a)        The Securities shall be signed on behalf of the
Trust by an Administrative Trustee by manual or facsimile signature.  In case
any Administrative Trustee of the Trust who shall have signed any of the
Securities shall cease to be such Administrative Trustee before the Securities
so signed shall be delivered by the Trust, such Securities nevertheless may be
delivered as though the person who signed such Securities had not ceased to be
such Administrative Trustee; and any Securities may be signed on behalf of the
Trust by such persons who, at the actual date of execution of such Security,
shall be the Administrative Trustees of the Trust, although at the date of the
execution and delivery of the Declaration any such person was not such an
Administrative Trustee.

                 (b)        One Administrative Trustee shall sign the Capital
Securities for the Trust by manual or facsimile signature.  Unless otherwise
determined by the Trust, such signature shall, in the case of Common
Securities, be a manual signature.

                 A Capital Security shall not be valid until authenticated by
the manual signature of an authorized officer of the Property Trustee.  The
signature shall be conclusive evidence that the Capital Security has been
authenticated under this Declaration.

                 Upon a written order of the Trust signed by one Administrative
Trustee, the Property Trustee shall authenticate the Capital Securities for
original issue.  The aggregate number of Capital Securities outstanding at any
time shall not exceed the number set forth in the Terms in Annex I hereto
except as provided in Section 7.6.

                 The Property Trustee may appoint an authenticating agent
acceptable to the Trust to authenticate Capital Securities.  An authenticating
agent may authenticate Capital Securities whenever the Property Trustee may do
so.  Each reference in this Declaration to authentication by the Property
Trustee includes authentication by such agent.  An authenticating agent has the
same rights as the Property Trustee to deal with the Sponsor or an Affiliate.

SECTION 7.3      Form and Dating.

                 The Capital Securities and the Property Trustee's certificate
of authentication shall be substantially in the form of Exhibit A-1 and the
Common Securities shall be substantially in the form of Exhibit A-2, each of
which is hereby incorporated in





                                      39
<PAGE>   46

and expressly made a part of this Declaration.  Certificates representing the
Securities may be printed, lithographed or engraved or may be produced in any
other manner as is reasonably acceptable to the Administrative Trustees, as
evidenced by their execution thereof.  The Securities may have letters, CUSIP
or other numbers, notations or other marks of identification or designation and
such legends or endorsements required by law, stock exchange rule, agreements
to which the Trust is subject, if any, or usage (provided that any such
notation, legend or endorsement is in a form acceptable to the Trust).  The
Trust at the direction of the Sponsor shall furnish any such legend not
contained in Exhibit A-1 to the Property Trustee in writing.  Each Capital
Security shall be dated the date of its authentication.  The terms and
provisions of the Securities set forth in Annex I and the forms of Securities
set forth in Exhibits A-1 and A-2 are part of the terms of this Declaration and
to the extent applicable, the Property Trustee and the Sponsor, by their
execution and delivery of this Declaration, expressly agree to such terms and
provisions and to be bound thereby.

                 (a)        Global Securities.  Securities offered and sold to
QIBs in reliance on Rule 144A as provided in the Purchase Agreement, shall be
issued in the form of one or more permanent global Securities in definitive,
fully registered global form without distribution coupons with the appropriate
global legend and applicable Restricted Securities Legend set forth in Exhibit
A-1 hereto (the "Global Capital Securities"), which shall be deposited upon
issuance with the Property Trustee as custodian for DTC, at its principal
Corporate Trust Office, and registered in the name of DTC or its nominee, in
each case for credit to an account of a direct or indirect participant in DTC
as described below.  The number of Capital Securities represented by the Global
Capital Security may from time to time be increased or decreased by adjustments
made on the records of the Property Trustee and the Clearing Agency or its
nominee as hereinafter provided.

                 (b)        Book-Entry Provisions.  This Section 7.3(b) shall
apply only to the Global Capital Securities and such other Capital Securities
in global form as may be authorized by the Trust to be deposited with or on
behalf of the Clearing Agency.

                 The Trust shall execute and the Property Trustee shall, in
accordance with this Section 7.3, authenticate and make available for delivery
initially one or more Global Capital Securities that (i) shall be registered in
the name of Cede & Co. or other nominee of such Clearing Agency and (ii) shall
be delivered by the Property Trustee to such Clearing Agency or pursuant to
such Clearing Agency's written instructions or held by the Property Trustee as
custodian for the Clearing Agency.





                                      40
<PAGE>   47

                 Members of, or participants in, the Clearing Agency
("Participants") shall have no rights under this Declaration with respect to
any Global Capital Security held on their behalf by the Clearing Agency or by
the Property Trustee as the custodian of the Clearing Agency or under such
Global Capital Security, and the Clearing Agency may be treated by the Trust,
the Property Trustee and any agent of the Trust or the Property Trustee as the
absolute owner of such Global Capital Security for all purposes whatsoever.
Notwithstanding the foregoing, nothing herein shall prevent the Trust, the
Property Trustee or any agent of the Trust or the Property Trustee from giving
effect to any written certification, proxy or other authorization furnished by
the Clearing Agency or impair, as between the Clearing Agency and its
Participants, the operation of customary practices of such Clearing Agency
governing the exercise of the rights of a holder of a beneficial interest in
any Global Capital Security.

                 (c)        Definitive Capital Securities.  Except as provided
in Section 7.9 or 9.2(f)(i), owners of beneficial interests in a Global Capital
Security will not be entitled to receive physical delivery of certificated
Capital Securities ("Definitive Capital Securities").  Purchasers of Securities
(other than QIBs) who are "accredited investors" (as defined in Rule 501(a)(1),
(2), (3) or (7) under the Securities Act) will receive Capital Securities in
the form of individual certificates in definitive, fully registered form
without distribution coupons and with the applicable Restricted Securities
Legend set forth in Exhibit A-1 hereto ("Restricted Definitive Capital
Securities"); provided, however, that upon transfer of such Restricted
Definitive Capital Securities to a QIB, such Restricted Definitive Capital
Securities will, unless the Global Capital Security has previously been
exchanged, be exchanged for an interest in a Global Capital Security pursuant
to the provisions of Section 9.2.  Restricted Definitive Capital Securities
will bear the applicable Restricted Securities Legend set forth on Exhibit A-1
unless removed in accordance with this Section 7.3 or Section 9.2.

                 (d)        Authorized Denominations.  The Capital Securities
are issuable only in denominations of $1,000 and any integral multiple thereof.

SECTION 7.4      Registrar, Paying Agent and Exchange Agent.

                 The Trust shall maintain in the Borough of Manhattan, The City
of New York, (i) an office or agency where Capital Securities may be presented
for registration of transfer ("Registrar"), (ii) an office or agency where
Capital Securities may be presented for payment ("Paying Agent") and (iii) an
office or agency where Securities may be presented for exchange ("Exchange
Agent").  The Registrar shall keep a register of the Capital Securities and of
their transfer.  The Trust may appoint the Registrar, the Paying Agent and the
Exchange Agent and may





                                      41
<PAGE>   48

appoint one or more co-registrars, one or more additional paying agents and one
or more additional exchange agents in such other locations as it shall
determine.  The term "Registrar" includes any additional registrar, "Paying
Agent" includes any additional paying agent and the term "Exchange Agent"
includes any additional exchange agent.  The Trust may change any Paying Agent,
Registrar, co-registrar or Exchange Agent without prior notice to any Holder.
The Paying Agent shall be permitted to resign as Paying Agent upon 30 days'
written notice to the Administrative Trustees.  The Trust shall notify the
Property Trustee of the name and address of any Agent not a party to this
Declaration.  If the Trust fails to appoint or maintain another entity as
Registrar, Paying Agent or Exchange Agent, the Property Trustee shall act as
such.  The Trust or any of its Affiliates may act as Paying Agent, Registrar,
or Exchange Agent.  The Trust shall act as Paying Agent, Registrar and Exchange
Agent for the Common Securities.

                 The Trust initially appoints the New York affiliate of the
Property Trustee as Registrar, Paying Agent and Exchange Agent for the Capital
Securities.

SECTION 7.5      Paying Agent to Hold Money in Trust.

                 The Trust shall require each Paying Agent other than the
Property Trustee to agree in writing that the Paying Agent will hold in trust
for the benefit of Holders or the Property Trustee all money held by the Paying
Agent for the payment of liquidation amounts or Distributions on the
Securities, and will notify the Property Trustee if there are insufficient
funds for such purpose.  While any such insufficiency continues, the Property
Trustee may require a Paying Agent to pay all money held by it to the Property
Trustee.  The Trust at any time may require a Paying Agent to pay all money
held by it to the Property Trustee and to account for any money disbursed by
it.  Upon payment over to the Property Trustee, the Paying Agent (if other than
the Trust or an Affiliate of the Trust) shall have no further liability for the
money.  If the Trust or the Sponsor or an Affiliate of the Trust or the Sponsor
acts as Paying Agent, it shall segregate and hold in a separate trust fund for
the benefit of the Holders all money held by it as Paying Agent.

SECTION 7.6      Replacement Securities.

                 If a Holder claims that a Security owned by it has been lost,
destroyed or wrongfully taken or if such Security is mutilated and is
surrendered to the Trust or in the case of the Capital Securities to the
Property Trustee, the Trust shall issue and the Property Trustee shall, upon
written order of the Trust, authenticate a replacement Security if the Property
Trustee's and the Trust's requirements, as the case may be, are met.  An
indemnity bond must be provided by the Holder which, in the judg-





                                      42
<PAGE>   49

ment of the Property Trustee, is sufficient to protect the Trustees, the
Sponsor, the Trust or any authenticating agent from any loss which any of them
may suffer if a Security is replaced.  The Trust may charge such Holder for its
expenses in replacing a Security.

                 Every replacement Security is an additional beneficial
interest in the Trust.

SECTION 7.7      Outstanding Capital Securities.

                 The Capital Securities outstanding at any time are all the
Capital Securities authenticated by the Property Trustee except for those
cancelled by it, those delivered to it for cancellation, and those described in
this Section as not outstanding.

                 If a Capital Security is replaced, pursuant to Section 7.6
hereof, it ceases to be outstanding unless the Property Trustee receives proof
satisfactory to it that the replaced Capital Security is held by a bona fide
purchaser.

                 If Capital Securities are considered paid in accordance with
the terms of this Declaration, they cease to be outstanding and Distributions
on them shall cease to accumulate.

                 A Capital Security does not cease to be outstanding because
one of the Trust, the Sponsor or an Affiliate of the Sponsor holds the
Security.

SECTION 7.8      Capital Securities in Treasury.

                 In determining whether the Holders of the required amount of
Securities have concurred in any direction, waiver or consent, Capital
Securities owned by the Trust, the Sponsor or an Affiliate of the Sponsor, as
the case may be, shall be disregarded and deemed not to be outstanding, except
that for the purposes of determining whether the Property Trustee shall be
fully protected in relying on any such direction, waiver or consent, only
Securities which the Property Trustee actually knows are so owned shall be so
disregarded.

SECTION 7.9      Temporary Securities.

                 (a)        Until definitive Securities are ready for delivery,
the Trust may prepare and, in the case of the Capital Securities, the Property
Trustee shall authenticate temporary Securities.  Temporary Securities shall be
substantially in the form of definitive Securities but may have variations that
the Trust considers appropriate for temporary Securities.  Without unreasonable
delay, the Trust shall prepare and, in the case of





                                      43
<PAGE>   50

the Capital Securities, the Property Trustee shall authenticate definitive
Securities in exchange for temporary Securities.

                 (b)        A Global Capital Security deposited with the
Clearing Agency or with the Property Trustee as custodian for the Clearing
Agency pursuant to Section 7.3 shall be transferred to the beneficial owners
thereof in the form of Definitive Capital Securities only if such transfer
complies with Section 9.2 and (i) the Clearing Agency notifies the Sponsor that
it is unwilling or unable to continue as Clearing Agency for such Global
Capital Security or if at any time such Clearing Agency ceases to be a
"clearing agency" registered under the Exchange Act and a clearing agency is
not appointed by the Sponsor within 90 days of such notice, (ii) a Default or
an Event of Default has occurred and is continuing or (iii) the Trust at its
sole discretion elects to cause the issuance of Definitive Capital Securities.

                 (c)        Any Global Capital Security that is transferable to
the beneficial owners thereof in the form of Definitive Capital Securities
pursuant to this Section 7.9 shall be surrendered by the Clearing Agency to the
Property Trustee located in the Borough of Manhattan, The City of New York, to
be so transferred, in whole or from time to time in part, without charge, and
the Property Trustee shall authenticate and make available for delivery, upon
such transfer of each portion of such Global Capital Security, an equal
aggregate liquidation amount of Securities of authorized denominations in the
form of Definitive Capital Securities.  Any portion of a Global Capital
Security transferred pursuant to this Section shall be registered in such names
as the Clearing Agency shall direct.  Any Capital Security in the form of
Definitive Capital Securities delivered in exchange for an interest in the
Restricted Capital Security in global form shall, except as otherwise provided
by Sections 7.3 and 9.2, bear the applicable Restricted Securities Legend set
forth in Exhibit A-1 hereto.

                 (d)        Subject to the provisions of Section 7.9(c), the
Holder of a Global Capital Security may grant proxies and otherwise authorize
any Person, including Participants and Persons that may hold interests through
Participants, to take any action which such Holder is entitled to take under
this Declaration or the Securities.

                 (e)        In the event of the occurrence of any of the events
specified in Section 7.9(b), the Trust will promptly make available to the
Property Trustee a reasonable supply of certificated Capital Securities in
fully registered form without distribution coupons.

SECTION 7.10     Cancellation.

                 The Trust at any time may deliver Capital Securities to the
Property Trustee for cancellation.  The Registrar, Paying Agent and Exchange
Agent shall forward to the Property Trustee any Capital Securities surrendered
to them for registration of transfer, redemption, exchange or payment.  The
Property Trustee shall promptly cancel all Capital Securities, surrendered for
registration of transfer, redemption, exchange, payment, replacement or
cancellation and shall dispose of cancelled Capital Securities as the Trust
directs, provided that the Property Trustee shall not be obligated to destroy
Capital Securities.  The Trust may not issue new Capital Securities to replace
Capital Securities that it has paid or that have been delivered to the Property
Trustee for cancellation or that any Holder has exchanged.

SECTION 7.11     CUSIP Numbers.

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

                              TERMINATION OF TRUST

SECTION 8.1      Termination of Trust.

                 (a)        The Trust shall automatically terminate:

                 (i)        upon the bankruptcy of the Sponsor;

                 (ii)       upon the filing of a certificate of dissolution or
         liquidation or its equivalent with respect to the Sponsor; or the
         revocation of the Sponsor's charter and the expiration of 90 days
         after the date of revocation without a reinstatement thereof;

                 (iii)      following the distribution of a Like Amount of the
         Debentures to the Holders, provided that, the Property Trustee has
         received written notice from the Sponsor directing the Property
         Trustee to terminate the Trust (which





                                      45
<PAGE>   52

         direction is optional, and except as otherwise expressly provided
         below, within the discretion of the Sponsor) and provided, further,
         that such direction and such distribution is conditioned on (a) the
         receipt by the Sponsor of the prior approval of the Federal Reserve
         Board if then required under applicable capital guidelines or policies
         of the Federal Reserve Board and (b) the Administrative Trustees'
         receipt of an opinion of an independent tax counsel experienced in
         such matters (a "No Recognition Opinion"), which opinion may rely on
         published rulings of the Internal Revenue Service, to the effect that
         the Holders will not recognize any gain or loss for United States
         federal income tax purposes as a result of the dissolution of the
         Trust and the distribution of Debentures;

                 (iv)       upon the entry of a decree of judicial dissolution
         of the Trust by a court of competent jurisdiction;

                 (v)        when all of the Securities shall have been called
         for redemption and the amounts necessary for redemption thereof shall
         have been paid to the Holders in accordance with the terms of the
         Securities; or

                 (vi)       the expiration of the term of the Trust provided in
         Section 3.14.

                 (b)        After the occurrence of an event referred to in
Section 8.1(a)(i), (ii), (iv), or (vi) above, the Administrative Trustees shall
liquidate the Trust as expeditiously as the Administrative Trustees determine
to be possible by causing the Property Trustee to distribute, after
satisfaction of liabilities to creditors of the Trust, as provided by
applicable law, to the holders of the Trust Securities a Like Amount of
Debentures, unless such distribution is determined by the Property Trustee not
to be practicable, in which event such holders will be entitled to receive out
of the assets of the Trust legally available for distribution to holders, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law, an amount equal to the aggregate of the liquidation amount plus
accumulated and unpaid Distributions thereon to the date of payment (such
amount being the "Liquidation Distribution").  If the Liquidation Distribution
can be paid only in part because the Trust has insufficient assets on hand
legally available to pay in full the aggregate Liquidation Distribution, then
the amounts payable directly by the Trust on the Capital Securities and the
Common Securities shall be paid on a pro rata basis, except that if an Event of
Default has occurred and is continuing, the Capital Securities shall have
priority over the Common Securities.  In any such case, the Administrative
Trustee shall cause a certificate of cancellation to be filed with the
Secretary of State of the State of Delaware.

                 (c)        The provisions of Section 3.9 and Article X shall
survive the termination of the Trust.


                                   ARTICLE IX
                             TRANSFER OF INTERESTS

SECTION 9.1      Transfer of Securities.

                 (a)        Securities may only be transferred, in whole or in
part, in accordance with the terms and conditions set forth in this Declaration
and in the terms of the Securities.  Any transfer or purported transfer of any
Security not made in accordance with this Declaration shall be null and void.

                 (b)        Subject to this Article IX, Capital Securities may
only be transferred, in whole or in part, in accordance with the terms and
conditions set forth in this Declaration.  Any transfer or purported transfer
of any Security not made in accordance with this Declaration shall be null and
void.

                 (c)        For so long as the Trust Securities remain
outstanding, the Sponsor will covenant to (i) maintain 100% ownership of the
Common Securities of the Trust; provided, however, that any permitted successor
of the Sponsor under the Indenture may succeed to the Sponsor's ownership of
such Common Securities, and (ii) use its reasonable efforts to cause the Trust
(a) to remain a statutory business trust, except in connection with a
distribution of Debentures to the holders of Trust Securities in liquidation of
the Trust, the redemption of all of the Trust Securities of the Trust or
certain mergers, consolidations or amalgamations, each as permitted by this
Declaration and (b) to continue not to be classified as an association taxable
as a corporation or partnership for United States federal income tax purposes
and (iii) to use its reasonable efforts to cause each holder of Trust
Securities to be treated as owning an undivided beneficial interest in the
Debentures.

                 (d)        The Administrative Trustees shall provide for the
registration of Securities and of the transfer of Securities, which will be
effected without charge but only upon payment (with such indemnity as the
Administrative Trustees may require) in respect of any tax or other
governmental charges that may be imposed in relation to it.  Upon surrender for
registration of transfer of any Securities, the Administrative Trustees shall
cause one or more new Securities to be issued in the name of the designated
transferee or transferees.  Every Security surrendered for registration of
transfer shall be accompanied by a written instrument of transfer in form
satisfactory to the Administrative Trustees duly executed by the Holder or such
Holder's attorney duly authorized in writing.  Each Security surrendered for
registration of transfer shall be canceled by the Property Trustee (in





                                      47
<PAGE>   54

the case of Capital Securities) or the Trust (in the case of Common
Securities).  A transferee of a Security shall be entitled to the rights and
subject to the obligations of a Holder hereunder upon the receipt by such
transferee of a Security.  By acceptance of a Security, each transferee shall
be deemed to have agreed to be bound by this Declaration.

SECTION 9.2      Transfer Procedures and Restrictions

                 (a)        General.  Except as otherwise provided in Section
9.2(b), if Capital Securities are issued upon the transfer, exchange or
replacement of Capital Securities bearing the Restricted Securities Legend set
forth in Exhibit A-1 hereto, or if a request is made to remove such Restricted
Securities Legend on Capital Securities, the Capital Securities so issued shall
bear the Restricted Securities Legend, or the Restricted Securities Legend
shall not be removed, as the case may be, unless there is delivered to the
Trust and the Property Trustee such evidence satisfactory to the Sponsor, which
shall include an Opinion of Counsel licensed to practice law in the State of
New York, as may be reasonably required by the Sponsor, that neither the legend
nor the restrictions on transfer set forth therein are required to ensure that
transfers thereof are made pursuant to an exception from the registration
requirements of the Securities Act or, with respect to Restricted Definitive
Capital Securities, that such Securities are not "restricted" within the
meaning of Rule 144.  Upon provision of such satisfactory evidence, the
Property Trustee, at the written direction of the Trust, shall authenticate and
deliver Capital Securities that do not bear the legend.

                 (b)        Transfers After Effectiveness of a Registration
Statement.  After the effectiveness of a Registration Statement with respect to
any Capital Securities, all requirements pertaining to legends on such Capital
Securities will cease to apply, and beneficial interests in a Capital Security
in global form without legends will be available to transferees of such Capital
Securities, upon exchange of the transferring Holder's Restricted Definitive
Capital Security or directions to transfer such Holder's beneficial interest in
the Global Capital Security.  No such transfer or exchange of a Restricted
Definitive Capital Security or of an interest in the Global Capital Security
shall be effective unless the transferor delivers to the Trust a certificate in
a form substantially similar to that attached hereto as the form of
"Assignment" in Exhibit A-1.  Except as otherwise provided in Section 9.2(l),
after the effectiveness of a Registration Statement, the Trust shall issue and
the Property Trustee, upon a written order of the Trust signed by one
Administrative Trustee, shall authenticate a Capital Security in global form
without the Restricted Securities Legend (the "Unrestricted Global Capital
Security") for deposit with the Clearing Agency or its custodian to evidence
transfers of beneficial interests from





                                      48
<PAGE>   55

the (i) Global Capital Security and (ii) Restricted Definitive Capital
Securities.

                 (c)        Transfer and Exchange of Definitive Capital
Securities.  When Definitive Capital Securities are presented to the Registrar
or co-Registrar

                 (x)  to register the transfer of such Definitive Capital
         Securities; or

                 (y)  to exchange such Definitive Capital Securities which
         became mutilated, destroyed, defaced, stolen or lost for an equal
         number of Definitive Capital Securities,

the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met;
provided, however, that the Definitive Capital Securities surrendered for
transfer or exchange:

                 (i)        shall be duly endorsed or accompanied by a written
         instrument of transfer in form reasonably satisfactory to the Trust
         and the Registrar or co-Registrar, duly executed by the Holder thereof
         or his attorney duly authorized in writing; and

                 (ii)       in the case of Definitive Capital Securities that
         are Restricted Definitive Capital Securities:

                            (A)     if such Restricted Capital Securities are
                 being delivered to the Registrar by a Holder for registration
                 in the name of such Holder, without transfer, a certification
                 from such Holder to that effect; or

                            (B)     if such Restricted Capital Securities are
                 being transferred:  (i) a certification from the transferor in
                 a form substantially similar to that attached hereto as the
                 form of "Assignment" in Exhibit A-1, and (ii) if the Trust so
                 requests, evidence reasonably satisfactory to it as to the
                 compliance with the restrictions set forth in the Restricted
                 Securities Legend.

                 (d)        Restrictions on Transfer of a Definitive Capital
Security for a Beneficial Interest in a Global Capital Security.  A Definitive
Capital Security may not be exchanged for a beneficial interest in a Global
Capital Security except upon satisfaction of the requirements set forth below.
Upon receipt by the Property Trustee of a Definitive Capital Security, duly
endorsed or accompanied by appropriate instruments of transfer, in form
satisfactory to the Property Trustee and Trust, together with:





                                      49
<PAGE>   56

                 (i)        if such Definitive Capital Security is a Restricted
         Capital Security, certification (in a form substantially similar to
         that attached hereto as the form of "Assignment" in Exhibit A-1); and

                 (ii)       whether or not such Definitive Capital Security is
         a Restricted Capital Security, written instructions directing the
         Property Trustee to make, or to direct the Clearing Agency to make, an
         adjustment on its books and records with respect to the appropriate
         Global Capital Security to reflect an increase in the number of the
         Capital Securities represented by such Global Capital Security,

then the Property Trustee shall cancel such Definitive Capital Security and
cause, or direct the Clearing Agency to cause, the aggregate number of Capital
Securities represented by the appropriate Global Capital Security to be
increased accordingly.  If no Global Capital Securities are then outstanding,
the Trust shall issue and the Property Trustee shall authenticate, upon written
order of any Administrative Trustee, an appropriate number of Capital
Securities in global form.

                 (e)        Transfer and Exchange of Global Capital Securities.
Subject to Section 9.2(f), the transfer and exchange of Global Capital
Securities or beneficial interests therein shall be effected through the
Clearing Agency, in accordance with this Declaration (including applicable
restrictions on transfer set forth herein, if any) and the procedures of the
Clearing Agency therefor.

                 (f)        Transfer of a Beneficial Interest in a Global
Capital Security for a Definitive Capital Security.

                 (i)        Any Person having a beneficial interest in a Global
         Capital Security may upon request, but only upon 20 days prior notice
         to the Property Trustee, and if accompanied by the information
         specified below, exchange such beneficial interest for a Definitive
         Capital Security representing the same number of Capital Securities.
         Upon receipt by the Property Trustee from the Clearing Agency or its
         nominee on behalf of any Person having a beneficial interest in a
         Global Capital Security of written instructions or such other form of
         instructions as is customary for the Clearing Agency or the Person
         designated by the Clearing Agency as having such a beneficial interest
         in a Restricted Capital Security and a certification from the
         transferor (in a form substantially similar to that attached hereto as
         the form of "Assignment" in Exhibit A-1), which may be submitted by
         facsimile, then the Property Trustee will cause the aggregate number
         of Capital Securities represented by Global Capital Securities to be
         reduced on its books and records and, following such reduction, the
         Trust will execute and the





                                      50
<PAGE>   57

         Property Trustee will authenticate and make available for delivery to
         the transferee a Definitive Capital Security.

                 (ii)       Definitive Capital Securities issued in exchange
         for a beneficial interest in a Global Capital Security pursuant to
         this Section 9.2(f) shall be registered in such names and in such
         authorized denominations as the Clearing Agency, pursuant to
         instructions from its Clearing Agency Participants or indirect
         participants or otherwise, shall instruct the Property Trustee in
         writing.  The Property Trustee shall deliver such Capital Securities
         to the Persons in whose names such Capital Securities are so
         registered in accordance with such instructions of the Clearing
         Agency.

                 (g)        Restrictions on Transfer and Exchange of Global
Capital Securities.  Notwithstanding any other provisions of this Declaration
(other than the provisions set forth in subsection (b) of Section 7.9), a
Global Capital Security may not be transferred as a whole except by the
Clearing Agency to a nominee of the Clearing Agency or another nominee of the
Clearing Agency or by the Clearing Agency or any such nominee to a successor
Clearing Agency or a nominee of such successor Clearing Agency.

                 (h)        Legend.

                 (i)        Except as permitted by the following paragraph
         (ii), each Capital Security certificate evidencing the Global Capital
         Securities and the Definitive Capital Securities (and all Capital
         Securities issued in exchange therefor or substitution thereof) shall
         bear a legend (the "Restricted Securities Legend") in substantially
         the following form, as applicable:

                 ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD,
                 ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE
                 DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH
                 TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, REGISTRATION.

                 THE HOLDER OF THIS CAPITAL SECURITY BY ITS ACCEPTANCE HEREOF
                 AGREES TO OFFER, SELL OR OTHERWISE TRANSFER THIS CAPITAL
                 SECURITY, PRIOR TO THE DATE (THE "RESALE RESTRICTION

         Global Capital Security) pursuant to an effective registration
         statement under the Securities Act or pursuant to Rule 144 under the
         Securities Act after such registration statement ceases to be
         effective:

                            (A)     in the case of any Restricted Capital
                 Security that is a Definitive Capital Security, the Registrar
                 shall permit the Holder thereof to exchange such Restricted
                 Capital Security for a Definitive Capital Security that does
                 not bear the Restricted Securities Legend and rescind any
                 restriction on the transfer of such Restricted Capital
                 Security; and

                            (B)     in the case of any Restricted Capital
                 Security that is represented by a Global Capital Security, the
                 Registrar shall permit the Holder of such Global Capital
                 Security to exchange such Global Capital Security for another
                 Global Capital Security that does not bear the Restricted
                 Securities Legend.

                 (i)        Cancellation or Adjustment of Global Capital
Security.  At such time as all beneficial interests in a Global Capital
Security have either been exchanged for Definitive Capital Securities to the
extent permitted by this Declaration or redeemed, repurchased or canceled in
accordance with the terms of this Declaration, such Global Capital Security
shall be returned to the Property Trustee for cancellation or retained and
canceled by the Property Trustee.  At any time prior to such cancellation, if
any beneficial interest in a Global Capital Security is exchanged for
Definitive Capital Securities, Capital Securities represented by such Global
Capital Security shall be reduced and an adjustment shall be made on the books
and records of the Property Trustee (if it is then the custodian for such
Global Capital Security) with respect to such Global Capital Security, by the





                                      53

Property Trustee or any securities custodian, to reflect such reduction.

                 (j)        Obligations with Respect to Transfers and Exchanges
of Capital Securities.

                 (i)        To permit registrations of transfers and exchanges,
         the Trust shall execute and the Property Trustee shall authenticate
         Definitive Capital Securities and Global Capital Securities at the
         Registrar's or co-Registrar's request in accordance with the terms of
         this Declaration.

                 (ii)       Registrations of transfers or exchanges will be
         effected without charge, but only upon payment (with such indemnity as
         the Trust or the Sponsor may require) in respect of any tax or other
         governmental charge that may be imposed in relation to it.

                 (iii)      The Registrar or co-registrar shall not be required
         to register the transfer of or exchange of (a) Capital Securities
         during a period beginning at the opening of business 15 days before
         the day of mailing of a notice of redemption or any notice of
         selection of Capital Securities for redemption and ending at the close
         of business on the day of such mailing; or (b) any Capital Security so
         selected for redemption in whole or in part, except the unredeemed
         portion of any Capital Security being redeemed in part.

                 (iv)       Prior to the due presentation for registration of
         transfer of any Capital Security, the Trust, the Property Trustee, the
         Paying Agent, the Registrar or any co-Registrar may deem and treat the
         Person in whose name a Capital Security is registered as the absolute
         owner of such Capital Security for the purpose of receiving
         Distributions on such Capital Security (subject to section 2(c) of
         Annex I) and for all other purposes whatsoever, and none of the Trust,
         the Property Trustee, the Paying Agent, the Registrar or any co-
         Registrar shall be affected by notice to the contrary.

                 (v)        All Capital Securities issued upon any transfer or
         exchange pursuant to the terms of this Declaration shall evidence the
         same security and shall be entitled to the same benefits under this
         Declaration as the Capital Securities surrendered upon such transfer
         or exchange.

                 (k)        No Obligation of the Property Trustee.

                 (i)        The Property Trustee shall have no responsibility
         or obligation to any beneficial owner of a Global Capital Security, a
         Clearing Agency Participant in the Clearing Agency or other Person
         with respect to the accuracy of the records of the Clearing Agency or
         its nominee or of any





                                      54
<PAGE>   61

         Clearing Agency Participant thereof, with respect to any ownership
         interest in the Capital Securities or with respect to the delivery to
         any Clearing Agency Participant, beneficial owner or other Person
         (other than the Clearing Agency) of any notice (including any notice
         of redemption) or the payment of any amount, under or with respect to
         such Capital Securities.  All notices and communications to be given
         to the Holders and all payments to be made to Holders under the
         Capital Securities shall be given or made only to or upon the order of
         the registered Holders (which shall be the Clearing Agency or its
         nominee in the case of a Global Capital Security).  The rights of
         beneficial owners in any Global Capital Security shall be exercised
         only through the Clearing Agency subject to the applicable rules and
         procedures of the Clearing Agency.  The Property Trustee may
         conclusively rely and shall be fully protected in relying upon
         information furnished by the Clearing Agency or any agent thereof with
         respect to its Clearing Agency Participants and any beneficial owners.

                 (ii)       The Property Trustee and the Registrar shall have
         no obligation or duty to monitor, determine or inquire as to
         compliance with any restrictions on transfer imposed under this
         Declaration or under applicable law with respect to any transfer of
         any interest in any Capital Security (including any transfers between
         or among Clearing Agency Participants or beneficial owners in any
         Global Capital Security) other than to require delivery of such
         certificates and other documentation or evidence as are expressly
         required by, and to do so if and when expressly required by, the terms
         of this Declaration, and to examine the same to determine substantial
         compliance as to form with the express requirements hereof.

                 (l)        Exchange of Series A Capital Securities for Series
B Capital Securities.  The Series A Capital Securities may be exchanged for
Series B Securities pursuant to the terms of the Exchange Offer.  The Property
Trustee shall make the exchange as follows:

                 The Sponsor shall present the Property Trustee with an
Officers' Certificate certifying the following:

                            (A)     upon issuance of the Series B Capital
                                    Securities, the transactions contemplated
                                    by the Exchange Offer have been
                                    consummated; and

                            (B)     the number of Series A Capital Securities
                                    properly tendered in the Exchange Offer
                                    that are represented by a Global Capital
                                    Security and the number of Series A Capital





                                      55

                            Securities properly tendered in the Exchange Offer
                            that are represented by Definitive Capital
                            Securities, the name of each Holder of such
                            Definitive Capital Securities, the liquidation
                            amount of Capital Securities properly tendered in
                            the Exchange Offer by each such Holder and the name
                            and address to which Definitive Capital Securities
                            for Series B Capital Securities shall be registered
                            and sent for each such Holder.

                 The Property Trustee, upon receipt of (i) such Officers'
Certificate, (ii) an Opinion of Counsel (x) to the effect that the Series B
Capital Securities have been registered under Section 5 of the Securities Act
and the Indenture has been qualified under the Trust Indenture Act and (y) with
respect to the matters set forth in Section 3(p) of the Registration Rights
Agreement and (iii) a Company Order, shall authenticate (A) a Global Capital
Security representing Series B Capital Securities in aggregate liquidation
amount equal to the aggregate liquidation amount of Series A Capital Securities
represented by a Global Capital Security indicated in such Officers'
Certificate as having been properly tendered and (B) Definitive Capital
Securities representing Series B Capital Securities registered in the names of,
and in the liquidation amounts indicated in such Officers' Certificate.

                 If, upon consummation of the Exchange Offer, less than all the
outstanding Series A Capital Securities shall have been properly tendered and
not withdrawn, the Property Trustee shall make an endorsement on the Global
Capital Security representing Series A Capital Securities indicating the
reduction in the number and aggregate liquidation amount represented thereby as
a result of the Exchange Offer.

                 The Trust shall deliver such Definitive Capital Securities
representing Series B Capital Securities to the Holders thereof as indicated in
such Officers' Certificate.

                 (m)        Minimum Transfers.  Series A Capital Securities may
only be transferred in minimum blocks of $100,000 aggregate liquidation amount
until such Series A Capital Securities are registered pursuant to an effective
registration statement filed under the Securities Act.  Any transfer of Series
A Capital Securities in a block having an aggregate liquidation amount of less
than $100,000 shall be deemed to be voided and of no legal effect whatsoever.
Any such transferee shall be deemed not to be a Holder of such Series A Capital
Securities for any purpose, including, but not limited to, the receipt of
Distributions on such Capital Securities, and such transferee shall be deemed
to have no interest whatsoever in such Capital Securities.

SECTION 9.3      Deemed Security Holders.

                 The Trustees may treat the Person in whose name any Security
shall be registered on the books and records of the Trust as the sole owner of
such Security for purposes of receiving Distributions and for all other
purposes whatsoever and, accordingly, shall not be bound to recognize any
equitable or other claim to or interest in such Security on the part of any
Person, whether or not the Trust shall have actual or other notice thereof.

SECTION 9.4      Book Entry Interests.

                 Global Capital Securities shall initially be registered on the
books and records of the Trust in the name of Cede & Co., the nominee of the
Clearing Agency, and no Capital Security Beneficial Owner will receive a
definitive Capital Security Certificate representing such Capital Security
Beneficial Owner's interests in such Global Capital Securities, except as
provided in Section 9.2 and Section 7.9.  Unless and until definitive, fully
registered Capital Securities certificates have been issued to the Capital
Security Beneficial Owners pursuant to Section 9.2 or Section 7.9:

                 (a)        the provisions of this Section 9.4 shall be in full
         force and effect;

                 (b)        the Trust and the Trustees shall be entitled to
         deal with the Clearing Agency for all purposes of this Declaration
         (including the payment of Distributions on the Global Capital
         Securities and receiving approvals, votes or consents hereunder) as
         the Holder of the Capital Securities and the sole holder of the Global
         Certificates and shall have no obligation to the Capital Security
         Beneficial Owners;

                 (c)        to the extent that the provisions of this Section
         9.4 conflict with any other provisions of this Declaration, the
         provisions of this Section 9.4 shall control; and

                 (d)        the rights of the Capital Security Beneficial
         Owners shall be exercised only through the Clearing Agency and shall
         be limited to those established by law and agreements between such
         Capital Security Beneficial Owners and the Clearing Agency and/or the
         Clearing Agency Participants shall receive and transmit payments of
         Distributions on the Global Certificates to such Clearing Agency
         Participants.  DTC will make book entry transfers among the Clearing
         Agency Participants.  Provided, that solely for the purposes of
         determining whether the Holders of the requisite amount of Capital
         Securities have voted on any matter provided for in this Declaration,
         so long as Definitive Capital Securities





                                      57
<PAGE>   64

         have not been issued, the Trustees may conclusively rely on, and shall
         be protected in relying on, any written instrument (including a proxy)
         delivered to the Trustees by the Clearing Agency setting forth the
         Capital Security Beneficial Owners' votes or assigning the right to
         vote on any matter to any other Persons either in whole or in part.

SECTION 9.5      Notices to Clearing Agency.

                 Whenever a notice or other communication to the Capital
Security Holders is required under this Declaration, the Trustees shall give
all such notices and communications specified herein to be given to the Holders
of Global Capital Securities to the Clearing Agency, and shall have no notice
obligations to the Capital Security Beneficial Owners.

SECTION 9.6      Appointment of Successor Clearing Agency.

                 If any Clearing Agency elects to discontinue its services as
securities depositary with respect to the Capital Securities, the
Administrative Trustees may, in their sole discretion, appoint a successor
Clearing Agency with respect to such Capital Securities.

                   HOLDERS OF SECURITIES, TRUSTEES OR OTHERS

SECTION 10.1     Liability.

                 (a)        Except as expressly set forth in this Declaration,
the Securities Guarantees and the terms of the Securities, the Sponsor shall
not be:

                 (i)        personally liable for the return of any portion of
         the capital contributions (or any return thereon) of the Holders which
         shall be made solely from assets of the Trust; and

                 (ii)       required to pay to the Trust or to any Holder of
         Securities any deficit upon dissolution or termination of the Trust or
         otherwise.

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

                 (c)        Pursuant to Section  3803(a) of the Business Trust
Act, the Holders shall be entitled to the same limitation of personal liability
extended to stockholders of private corporations for





                                      58

profit organized under the General Corporation Law of the State of Delaware.

SECTION 10.2     Exculpation.

                 (a)        No Indemnified Person shall be liable, responsible
or accountable in damages or otherwise to the Trust or any Covered Person for
any loss, damage or claim incurred by reason of any act or omission performed
or omitted by such Indemnified Person in good faith on behalf of the Trust and
in a manner such Indemnified Person reasonably believed to be within the scope
of the authority conferred on such Indemnified Person by this Declaration or by
law, except that an Indemnified Person shall be liable for any such loss,
damage or claim incurred by reason of such Indemnified Person's gross
negligence or willful misconduct with respect to such acts or omissions.

                 (b)        An Indemnified Person shall be fully protected in
relying in good faith upon the records of the Trust and upon such information,
opinions, reports or statements presented to the Trust by any Person as to
matters the Indemnified Person reasonably believes are within such other
Person's professional or expert competence and, if selected by such Indemnified
Person, has been selected by such Indemnified Person with reasonable care on
behalf of the Trust, including information, opinions, reports or statements as
to the value and amount of the assets, liabilities, profits, losses, or any
other facts pertinent to the existence and amount of assets from which
Distributions to Holders might properly be paid.

SECTION 10.3     Fiduciary Duty.

                 (a)        To the extent that, at law or in equity, an
Indemnified Person has duties (including fiduciary duties) and liabilities
relating thereto to the Trust or to any other Covered Person, an Indemnified
Person acting under this Declaration shall not be liable to the Trust or to any
other Covered Person for its good faith reliance on the provisions of this
Declaration.  The provisions of this Declaration, to the extent that they
restrict the duties and liabilities of an Indemnified Person otherwise existing
at law or in equity (other than the duties imposed on the Property Trustee
under the Trust Indenture Act), are agreed by the parties hereto to replace
such other duties and liabilities of such Indemnified Person.

                 (b)        Unless otherwise expressly provided herein:

                 (i)        whenever a conflict of interest exists or arises
between any Covered Persons; or

                 (ii)       whenever this Declaration or any other agreement
contemplated herein or therein provides that an Indemnified





                                      59
<PAGE>   66

         Person shall act in a manner that is, or provides terms that are, fair
         and reasonable to the Trust or any Holder of Securities,

the Indemnified Person shall resolve such conflict of interest, take such
action or provide such terms, considering in each case the relative interest of
each party (including its own interest) to such conflict, agreement,
transaction or situation and the benefits and burdens relating to such
interests, any customary or accepted industry practices, and any applicable
generally accepted accounting practices or principles.  In the absence of bad
faith by the Indemnified Person, the resolution, action or term so made, taken
or provided by the Indemnified Person shall not constitute a breach of this
Declaration or any other agreement contemplated herein or of any duty or
obligation of the Indemnified Person at law or in equity or otherwise.

                 (c)        Whenever in this Declaration an Indemnified Person
is permitted or required to make a decision:

                 (i)        in its "discretion" or under a grant of similar
         authority, the Indemnified Person shall be entitled to consider such
         interests and factors as it desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

                 (ii)       in its "good faith" or under another express
         standard, the Indemnified Person shall act under such express standard
         and shall not be subject to any other or different standard imposed by
         this Declaration.

SECTION 10.4     Indemnification.

                 (a)  (i)  The Debenture Issuer shall indemnify, to the full
         extent permitted by law, any Company Indemnified Person who was or is
         a party or is threatened to be made a party to any threatened, pending
         or completed action, suit or proceeding, whether civil, criminal,
         administrative or investigative (other than an action by or in the
         right of the Trust) by reason of the fact that he is or was a Company
         Indemnified Person against expenses (including attorneys' fees and
         expenses), judgments, fines and amounts paid in settlement actually
         and reasonably incurred by him in connection with such action, suit or
         proceeding if he acted in good faith and in a manner he reasonably
         believed to be in or not opposed to the best interests of the Trust,
         and, with respect to any criminal action or proceeding, had no
         reasonable cause to believe his conduct was unlawful.  The termination
         of any action, suit or proceeding by judgment, order, settlement,
         conviction, or upon a plea of nolo contendere or its equivalent, shall
         not, of itself, create a presumption





                                      60
<PAGE>   67

         that the Company Indemnified Person did not act in good faith and in a
         manner which he reasonably believed to be in or not opposed to the
         best interests of the Trust, and, with respect to any criminal action
         or proceeding, had reasonable cause to believe that his conduct was
         unlawful.

                 (ii)       The Debenture Issuer shall indemnify, to the full
         extent permitted by law, any Company Indemnified Person who was or is
         a party or is threatened to be made a party to any threatened, pending
         or completed action or suit by or in the right of the Trust to procure
         a judgment in its favor by reason of the fact that he is or was a
         Company Indemnified Person against expenses (including attorneys' fees
         and expenses) actually and reasonably incurred by him in connection
         with the defense or settlement of such action or suit if he acted in
         good faith and in a manner he reasonably believed to be in or not
         opposed to the best interests of the Trust and except that no such
         indemnification shall be made in respect of any claim, issue or matter
         as to which such Company Indemnified Person shall have been adjudged
         to be liable to the Trust unless and only to the extent that the Court
         of Chancery of Delaware or the court in which such action or suit was
         brought shall determine upon application that, despite the
         adjudication of liability but in view of all the circumstances of the
         case, such Person is fairly and reasonably entitled to indemnity for
         such expenses which such Court of Chancery or such other court shall
         deem proper.

                 (iii)      To the extent that a Company Indemnified Person
         shall be successful on the merits or otherwise (including dismissal of
         an action without prejudice or the settlement of an action without
         admission of liability) in defense of any action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 10.4(a), or in
         defense of any claim, issue or matter therein, he shall be
         indemnified, to the full extent permitted by law, against expenses
         (including attorneys' fees) actually and reasonably incurred by him in
         connection therewith.

                 (iv)       Any indemnification under paragraphs (i) and (ii)
         of this Section 10.4(a) (unless ordered by a court) shall be made by
         the Debenture Issuer only as authorized in the specific case upon a
         determination that indemnification of the Company Indemnified Person
         is proper in the circumstances because he has met the applicable
         standard of conduct set forth in paragraphs (i) and (ii).  Such
         determination shall be made (1) by the Administrative Trustees by a
         majority vote of a Quorum consisting of such Administrative Trustees
         who were not parties to such action, suit or proceeding, (2) if such a

         Trustees so directs, by independent legal counsel in a written
         opinion, or (3) by the Common Security Holder of the Trust.

                 (v)        Expenses (including attorneys' fees and expenses)
         incurred by a Company Indemnified Person in defending a civil,
         criminal, administrative or investigative action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 10.4(a) shall
         be paid by the Debenture Issuer in advance of the final disposition of
         such action, suit or proceeding upon receipt of an undertaking by or
         on behalf of such Company Indemnified Person to repay such amount if
         it shall ultimately be determined that he is not entitled to be
         indemnified by the Debenture Issuer as authorized in this Section
         10.4(a).  Notwithstanding the foregoing, no advance shall be made by
         the Debenture Issuer if a determination is reasonably and promptly
         made (i) by the Administrative Trustees by a majority vote of a Quorum
         of disinterested Administrative Trustees, (ii) if such a Quorum is not
         obtainable, or, even if obtainable, if a Quorum of disinterested
         Administrative Trustees so directs, by independent legal counsel in a
         written opinion or (iii) the Common Security Holder of the Trust,
         that, based upon the facts known to the Administrative Trustees,
         counsel or the Common Security Holder at the time such determination
         is made, such Company Indemnified Person acted in bad faith or in a
         manner that such person did not believe to be in or not opposed to the
         best interests of the Trust, or, with respect to any criminal
         proceeding, that such Company Indemnified Person believed or had
         reasonable cause to believe his conduct was unlawful.  In no event
         shall any advance be made in instances where the Administrative
         Trustees, independent legal counsel or Common Security Holder
         reasonably determine that such person deliberately breached his duty
         to the Trust or its Common or Capital Security Holders.

                 (vi)       The indemnification and advancement of expenses
         provided by, or granted pursuant to, the other paragraphs of this
         Section 10.4(a) shall not be deemed exclusive of any other rights to
         which those seeking indemnification and advancement of expenses may be
         entitled under any agreement, vote of stockholders or disinterested
         directors of the Debenture Issuer or Capital Security Holders of the
         Trust or otherwise, both as to action in his official capacity and as
         to action in another capacity while holding such office.  All rights
         to indemnification under this Section 10.4(a) shall be deemed to be
         provided by a contract between the Debenture Issuer and each Company
         Indemnified Person who serves in such capacity at any time while this
         Section 10.4(a) is in effect.  Any repeal or modification of this
         Section 10.4(a) shall not affect any rights or obligations then
         existing.

                 (vii)      The Debenture Issuer or the Trust may purchase and
         maintain insurance on behalf of any person who is or was a Company
         Indemnified Person against any liability asserted against him and
         incurred by him in any such capacity, or arising out of his status as
         such, whether or not the Debenture Issuer would have the power to
         indemnify him against such liability under the provisions of this
         Section 10.4(a).

                 (viii)     For purposes of this Section 10.4(a), references to
         "the Trust" shall include, in addition to the resulting or surviving
         entity, any constituent entity (including any constituent of a
         constituent) absorbed in a consolidation or merger, so that any person
         who is or was a director, trustee, officer or employee of such
         constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee or agent
         of another entity, shall stand in the same position under the
         provisions of this Section 10.4(a) with respect to the resulting or
         surviving entity as he would have with respect to such constituent
         entity if its separate existence had continued.

                 (ix)       The indemnification and advancement of expenses
         provided by, or granted pursuant to, this Section 10.4(a) shall,
         unless otherwise provided when authorized or ratified, continue as to
         a person who has ceased to be a Company Indemnified Person and shall
         inure to the benefit of the heirs, executors and administrators of
         such a person.

                 (b)        The Debenture Issuer agrees to indemnify the (i)
Property Trustee, (ii) the Delaware Trustee, (iii) any Affiliate of the
Property Trustee and the Delaware Trustee, and (iv) any officers, directors,
shareholders, members, partners, employees, representatives, custodians,
nominees or agents of the Property Trustee and the Delaware Trustee (each of
the Persons in (i) through (iv) being referred to as a "Fiduciary Indemnified
Person") for, and to hold each Fiduciary Indemnified Person harmless against,
any and all loss, liability, damage, claim or expense including taxes (other
than taxes based on the income of such Fiduciary Indemnified Person) incurred
without negligence or bad faith on its part, arising out of or in connection
with the acceptance or administration of the trust or trusts hereunder,
including the costs and expenses (including reasonable legal fees and expenses)
of defending itself against or investigating any claim or liability in
connection with the exercise or performance of any of its powers or duties
hereunder.  The provisions of Section 10.4(b) shall survive the termination of
this Declaration and the resignation or removal of the Property Trustee or the
Delaware Trustee, as the case may be.

SECTION 10.5     Outside Businesses.

                 Any Covered Person, the Sponsor, the Delaware Trustee and the
Property Trustee (subject to Section 5.3(c)) may engage in or possess an
interest in other business ventures of any nature or description, independently
or with others, similar or dissimilar to the business of the Trust, and the
Trust and the Holders shall have no rights by virtue of this Declaration in and
to such independent ventures or the income or profits derived therefrom, and
the pursuit of any such venture, even if competitive with the business of the
Trust, shall not be deemed wrongful or improper.  No Covered Person, the
Sponsor, the Delaware Trustee, or the Property Trustee shall be obligated to
present any particular investment or other opportunity to the Trust even if
such opportunity is of a character that, if presented to the Trust, could be
taken by the Trust, and any Covered Person, the Sponsor, the Delaware Trustee
and the Property Trustee shall have the right to take for its own account
(individually or as a partner or fiduciary) or to recommend to others any such
particular investment or other opportunity.  Any Covered Person, the Delaware
Trustee and the Property Trustee may engage or be interested in any financial
or other transaction with the Sponsor or any Affiliate of the Sponsor, or may
act as depositary for, trustee or agent for, or act on any committee or body of
holders of, securities or other obligations of the Sponsor or its Affiliates.

SECTION 10.6     Compensation; Fees.

                 The Debenture Issuer agrees:

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

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

                 The provisions of this Section 10.6 shall survive the
dissolution of the Trust and the termination of this Declaration and the
removal or resignation of any Trustee.

                 No Trustee may claim any lien or charge on any property of the
Trust as a result of any amount due pursuant to this Section 10.6

                                   ACCOUNTING

SECTION 11.1     Fiscal Year.

                 The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

SECTION 11.2     Certain Accounting Matters.

                 (a)        At all times during the existence of the Trust, the
Administrative Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail,
each transaction of the Trust.  The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied.  [The Trust shall use the accrual method of
accounting for United States federal income tax purposes.]  The books of
account and the records of the Trust shall be examined by and reported upon as
of the end of each Fiscal Year of the Trust by a firm of independent certified
public accountants selected by the Administrative Trustees.

                 (b)        The Administrative Trustees shall cause to be duly
prepared and delivered to each of the Holders, any annual United States federal
income tax information statement, required by the Code, containing such
information with regard to the Securities held by each Holder as is required by
the Code and the Treasury Regulations.  Notwithstanding any right under the
Code to deliver any such statement at a later date, the Administrative Trustees
shall endeavor to deliver all such information statements within 30 days after
the end of each Fiscal Year of the Trust.

                 (c)        The Administrative Trustees shall cause to be duly
prepared and filed with the appropriate taxing authority, an annual United
States federal income tax return, on a Form 1041 or such other form required by
United States federal income tax law, and any other annual income tax returns
required to be filed by the Administrative Trustees on behalf of the Trust with
any state or local taxing authority.

SECTION 11.3     Banking.

                 The Trust may maintain one or more bank accounts in the name
and for the sole benefit of the Trust; provided, however, that all payments of
funds in respect of the Debentures held by the Property Trustee shall be made
directly to the Property Trustee Account and no other funds of the Trust shall
be deposited in the Property Trustee Account.  The sole signatories for such
accounts shall be designated by the Administrative Trustees; provided, however,
that the Property Trustee shall designate the





                                      65
<PAGE>   72

signatories for the Property Trustee Account.

SECTION 11.4     Withholding.

                 The Trust and the Administrative Trustees shall comply with
all withholding requirements under United States federal, state and local law.
The Trust shall request, and the Holders shall provide to the Trust, such forms
or certificates as are necessary to establish an exemption from withholding
with respect to each Holder, and any representations and forms as shall
reasonably be requested by the Trust to assist it in determining the extent of,
and in fulfilling, its withholding obligations.  The Administrative Trustees
shall file required forms with applicable jurisdictions and, unless an
exemption from withholding is properly established by a Holder, shall remit
amounts withheld with respect to the Holder to applicable jurisdictions.  To
the extent that the Trust is required to withhold and pay over any amounts to
any authority with respect to Distributions or allocations to any Holder, the
amount withheld shall be deemed to be a Distribution in the amount of the
withholding to the Holder.  In the event of any claimed over withholding,
Holders shall be limited to an action against the applicable jurisdiction.  If
the amount required to be withheld was not withheld from actual Distributions
made, the Trust may reduce subsequent Distributions by the amount of such
withholding.

amendment shall be void and ineffective:

                 the terms of the Securities),

provided, however, that the Property Trustee shall not be required to sign any
such amendment which affects the rights, powers, duties, obligations or
immunities of the Property Trustee, and

                 (ii)       to the extent the result of such amendment would be
        to:

                            (A)     cause the Trust to fail to continue to be
                 classified for purposes of United States federal income

                 Investment Company required to be registered under the
                 Investment Company Act;

                 (c)        At such time after the Trust has issued any
Securities that remain outstanding, any amendment that would adversely affect
the rights, privileges or preferences of any Holder may be effected only with
such additional requirements as may be set forth in the terms of such
Securities;

                 (d)        Section 9.1(c) and this Section 12.1 shall not be
amended without the consent of all of the Holders;

                 (e)        Article Four shall not be amended without the

                 (f)        The rights of the holders of the Common Securities
under Article Five to increase or decrease the number of, and appoint and
remove Trustees shall not be amended without the consent of the Holders of a

         shall not be inconsistent with the other provisions of the
         Declaration; and

                 (ii)       to modify, eliminate or add to any provisions of
         the Declaration to such extent as shall be necessary to ensure that
         the Trust will be classified for United States federal income tax
         purposes as a grantor trust at all times that any Securities are
         outstanding or to ensure that the Trust will not be required to
         register as an Investment Company under the Investment Company Act.

provided, however, that in the case of clause (i), such action shall not
adversely affect in any material respect the interests of the Holders, and any
amendments of this Declaration shall become effective when notice thereof is
given to the Holders.

SECTION 12.2     Meetings of the Holders; Action by Written Consent.

                 (a)        Meetings of the Holders of any class of Securities
may be called at any time by the Administrative Trustees (or as provided in the
terms of the Securities) to consider and act on any matter on which Holders of
such class of Securities are entitled to act under the terms of this
Declaration, the terms of the Securities or the rules of any stock exchange on
which the Capital Securities are listed or admitted for trading.  The
Administrative Trustees shall call a meeting of the Holders of such class if
directed to do so by the Holders of at least 10% in liquidation amount of such
class of Securities.  Such direction shall be given by delivering to the
Administrative Trustees one or more notices in writing stating that the signing
Holders wish to call a meeting and indicating the general or specific purpose
for which the meeting is to be called.  Any Holders calling a meeting shall
specify in writing the Security Certificates held by the Holders exercising the
right to call a meeting and only those Securities specified shall be counted
for purposes of determining whether the required percentage set forth in the
second sentence of this paragraph has been met.

                 (b)        Except to the extent otherwise provided in the
terms of the Securities, the following provisions shall apply to meetings of
Holders:

                 (i)        notice of any such meeting shall be given to all
         the Holders having a right to vote thereat at least seven days and not
         more than 60 days before the date of such meeting.  Whenever a vote,
         consent or approval of the Holders is permitted or required under this
         Declaration or the rules of





                                      68
<PAGE>   75

         any stock exchange on which the Capital Securities are listed or
         admitted for trading, such vote, consent or approval may be given at a
         meeting of the Holders.  Any action that may be taken at a meeting of
         the Holders may be taken without a meeting if a consent in writing
         setting forth the action so taken is signed by the Holders owning not
         less than the minimum amount of Securities in liquidation amount that
         would be necessary to authorize or take such action at a meeting at
         which all Holders having a right to vote thereon were present and
         voting.  Prompt notice of the taking of action without a meeting shall
         be given to the Holders entitled to vote who have not consented in
         writing.  The Administrative Trustees may specify that any written
         ballot submitted to the Security Holder for the purpose of taking any
         action without a meeting shall be returned to the Trust within the
         time specified by the Administrative Trustees;

                 (ii)       each Holder may authorize any Person to act for it
         by proxy on all matters in which a Holder is entitled to participate,
         including waiving notice of any meeting, or voting or participating at
         a meeting.  No proxy shall be valid after the expiration of 11 months
         from the date thereof unless otherwise provided in the proxy.  Every
         proxy shall be revocable at the pleasure of the Holder executing it.
         Except as otherwise provided herein, all matters relating to the
         giving, voting or validity of proxies shall be governed by the General
         Corporation Law of the State of Delaware relating to proxies, and
         judicial interpretations thereunder, as if the Trust were a Delaware
         corporation and the Holders were stockholders of a Delaware
         corporation;

                 (iii)      each meeting of the Holders shall be conducted by
         the Administrative Trustees or by such other Person that the
         Administrative Trustees may designate; and

                 (iv)       unless the Business Trust Act, this Declaration,
         the terms of the Securities, the Trust Indenture Act or the listing
         rules of any stock exchange on which the Capital Securities are then
         listed or trading, otherwise provides, the Administrative Trustees, in
         their sole discretion, shall establish all other provisions relating
         to meetings of Holders, including notice of the time, place or purpose
         of any meeting at which any matter is to be voted on by any Holders,
         waiver of any such notice, action by consent without a meeting, the
         establishment of a record date, quorum requirements, voting in person
         or by proxy or any other matter with respect to the exercise of any
         such right to vote.

                                    ANNEX I


                                    TERMS OF
                   SERIES A/SERIES B 9.35% CAPITAL SECURITIES
                            9.35% COMMON SECURITIES


                 Pursuant to Section 7.1 of the Amended and Restated
Declaration of Trust, dated as of March 25, 1997 (as amended from time to time,
the "Declaration"), the designation, rights, privileges, restrictions,
preferences and other terms and provisions of the Securities are set out below
(each capitalized term used but not defined herein has the meaning set forth in
the Declaration or, if not defined in such Declaration, as defined in the
Offering Memorandum referred to below in Section 2(c) of this Annex I):

                 1.       Designation and Number.

                 (a)      Capital Securities.  40,000 Series A Capital
Securities of the Trust and 40,000 Series B Capital Securities of the Trust,
each series with an aggregate liquidation amount with respect to the assets of
the Trust of Forty Million Dollars ($40,000,000), and each Capital Security
with a liquidation amount with respect to the assets of the Trust of $1,000 per
Security, are hereby designated for the purposes of identification only as
"Series A 9.35% Capital Securities" and "Series B 9.35% Capital Securities",
respectively (collectively, the "Capital Securities").  The certificates
evidencing the Capital Securities shall be substantially in the form of Exhibit
A-1 to the Declaration, with such changes and additions thereto or deletions
therefrom as may be required by ordinary usage, custom or practice or to
conform to the rules of any exchange or quotation system on or in which the
Capital Securities are listed, traded or quoted.

                 (b)      Common Securities.  1,238 Common Securities of the
Trust with an aggregate liquidation amount with respect to the assets of the
Trust of One Million Two Hundred Thirty-Eight Thousand Dollars ($1,238,000) and
each Common Security with a liquidation amount with respect to the assets of
the Trust of $1,000 per Security, are hereby designated for the purposes of
identification only as "9.35% Common Securities" (the "Common Securities").
The certificates evidencing the Common Securities shall be substantially in the
form of Exhibit A-2 to the Declaration, with such changes and additions thereto
or deletions therefrom as may be required by ordinary usage, custom or
practice.

                 2.       Distributions.

                 (a)      Distributions payable on each Security will be fixed
at a rate per annum of 9.35% (the "Coupon Rate") of the liquidation amount of
$1,000 per Security (the "Liquidation Amount"), such rate being the rate of
interest payable on the Debentures to be held by the Property Trustee.
Distributions in arrears for more than one semi-annual period will bear
additional distributions thereon compounded semi-annually at the Coupon Rate
(to the extent permitted by applicable law).  Pursuant to the Registration
Rights Agreement, in certain limited circumstances the Debenture Issuer will be
required to pay Liquidated Damages (as defined in the Registration Rights
Agreement) with respect to the Debentures.  The term "Distributions", as used
herein, includes distributions of any such interest and Liquidated Damages
payable unless otherwise stated.  A Distribution is payable only to the extent
that payments are made in respect of the Debentures held by the Property
Trustee and to the extent the Property Trustee has funds on hand legally
available therefor.

                 (b)      Distributions on the Securities will be cumulative,
will accumulate from the most recent date to which Distributions have been paid
or duly provided for or, if no Distributions have been paid or duly provided
for, from March 25, 1997 and will be payable semi-annually in arrears on June
15 and December 15 of each year, commencing on June 15, 1997 (each, a
"Distribution Date"), except as otherwise described below.  Distributions will
be computed on the basis of a 360-day year consisting of twelve 30-day months
and for any period less than a full calendar month on the basis of the actual
number of days elapsed in such month.  As long as no Event of Default has
occurred and is continuing under the Indenture, the Debenture Issuer has the
right under the Indenture to defer payments of interest by extending the
interest payment period at any time and from time to time on the Debentures for
a period not exceeding 10 consecutive semi-annual periods, including the first
such semi-annual period during such period (each an "Extension Period"), during
which Extension Period no interest shall be due and payable on the Debentures,
provided that no Extension Period shall end on a date other than an Interest
Payment Date for the Debentures or extend beyond the Maturity Date of the
Debentures.  As a consequence of such deferral, Distributions will also be
deferred.  Despite such deferral, Distributions will continue to accumulate
with additional Distributions thereon (to the extent permitted by applicable
law but not at a rate greater than the rate at which interest is then accruing
on the Debentures) at the Coupon Rate compounded semi-annually during any such
Extension Period.  Prior to the termination of any such Extension Period, the
Debenture Issuer may further defer payments of interest by further extending
such Extension Period; provided that such Extension Period, together with all
such previous and further extensions within such Extension Period, may not
exceed 10 con-


                                     I-2

<PAGE>   84

secutive semi-annual periods, including the first semi-annual period during such
Extension Period, or extend beyond the Maturity Date of the Debentures. 
Upon the termination of any Extension Period and the payment of all amounts then
due, the Debenture Issuer may commence a new Extension Period, subject to the
above requirements.

                 (c)      Distributions on the Securities will be payable to
the Holders thereof as they appear on the books and records of the Trust on the
close of business on the 15th day of the month immediately preceding the month
in which the relevant Distribution Date occurs, which Distribution Dates
correspond to the interest payment dates on the Debentures.  Subject to any
applicable laws and regulations and the provisions of the Declaration, each
such payment in respect of the Capital Securities will be made as described
under the heading "Description of the Capital Securities -- Form, Denomination,
Book-Entry Procedures and Transfer" in the Offering Memorandum dated March 19,
1997 of the Debenture Issuer and the Trust relating to the Securities and the
Debentures.  The relevant record dates for the Common Securities shall be the
same as the record dates for the Capital Securities.  Distributions payable on
any Securities that are not punctually paid on any Distribution Date, as a
result of the Debenture Issuer having failed to make a payment under the
Debentures, will cease to be payable to the Holder on the relevant record date,
and such defaulted Distribution will instead be payable to the Person in whose
name such Securities are registered on the special record date or other
specified date determined in accordance with the Indenture.  If any date on
which Distributions are payable on the Securities is not a Business Day, then
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 of any such delay), except that if such next succeeding
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 such date.

                 (d)      In the event that there is any money or other
property held by or for the Trust that is not accounted for hereunder, such
property shall be distributed Pro Rata (as defined herein) among the Holders.

                 3.       Liquidation Distribution Upon Dissolution.

                 In the event of any termination of the Trust or the Sponsor
otherwise gives notice of its election to liquidate the Trust pursuant to
Section 8.1(a)(iii) of the Declaration, the Trust shall be liquidated by the
Administrative Trustees as expeditiously as the Administrative Trustees
determine to be possible by distributing, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, to the





                                     I-3
<PAGE>   85

Holders a Like Amount (as defined below) of the Debentures, unless such
distribution is determined by the Property Trustee not to be practicable, in
which event such Holders will be entitled to receive Pro Rata out of the assets
of the Trust legally available for distribution to Holders, after satisfaction
of liabilities to creditors of the Trust as provided by applicable law, an
amount equal to the aggregate of the liquidation amount of $1,000 per Security
plus accumulated and unpaid Distributions thereon to the date of payment (such
amount being the "Liquidation Distribution").

                 "Like Amount" means (i) with respect to a redemption of the
Securities, Securities having a Liquidation Amount equal to the principal
amount of Debentures to be paid in accordance with their terms and (ii) with
respect to a distribution of Debentures upon the liquidation of the Trust,
Debentures having a principal amount equal to the Liquidation Amount of the
Securities of the Holder to whom such Debentures are distributed.

                 If, upon any such liquidation, the Liquidation Distribution
can be paid only in part because the Trust has insufficient assets on hand
legally available to pay in full the aggregate Liquidation Distribution, then
the amounts payable directly by the Trust on the Securities shall be paid on a
Pro Rata basis.

                 4.       Redemption and Distribution.

                 (a)      Upon the repayment of the Debentures in whole or in
part, at maturity or upon early redemption (either at the option of the
Debenture Issuer or pursuant to a Special Event, as described below), the
proceeds from such repayment shall be simultaneously applied by the Property
Trustee (subject to the Property Trustee having received written notice no
later than 45 days prior to such repayment) to redeem a Like Amount of the
Securities at a redemption price equal to (i) in the case of the repayment of
the Debentures at maturity, the Maturity Redemption Price (as defined below),
(ii) in the case of the optional redemption of the Debentures upon the
occurrence and continuation of a Special Event, the Special Event Redemption
Price (as defined below) and (iii) in the case of the optional redemption of
the Debentures on or after March 1, 2007 (the "Initial Optional Redemption
Date"), the Optional Redemption Price (as defined below).  The Maturity
Redemption Price, the Special Event Redemption Price and the Optional
Redemption Price are referred to collectively as the "Redemption Price".
Holders will be given not less than 30 nor more than 60 days notice of such
redemption.

                 (b)  (i)  The "Maturity Redemption Price", with respect to a
redemption of Securities, shall mean an amount equal to the principal of and
accrued and unpaid interest on the Debentures as of the maturity date thereof.





                                     I-4
<PAGE>   86

                 (ii)  In the case of an optional redemption, if fewer than all
the outstanding Securities are to be so redeemed, the Securities to be redeemed
will be determined as described in Section 4(f)(ii) below.  Upon the entry of
an order for the dissolution of the Trust by a court of competent jurisdiction,
the Debentures thereafter will be subject to optional repayment, in whole, but
not in part, on or after the Initial Optional Redemption Date.

                 The Debenture Issuer shall have the right (subject to the
conditions in the Indenture) to elect to redeem the Debentures in whole or in
part at any time on or after the Initial Optional Redemption Date, upon not
less than 30 days and not more than 60 days notice, at the Optional Redemption
Price and, simultaneous with such redemption, to cause a Like Amount of the
Securities to be redeemed by the Trust at the Optional Redemption Price on a
Pro Rata basis.  "Optional Redemption Price" shall mean a price equal to the
percentage of the liquidation amount of Securities to be redeemed plus
accumulated and unpaid Distributions thereon, if any, to the date of such
redemption; if redeemed during the 12-month period beginning March 1 of the
years indicated below:

                 (c)      If at any time a Tax Event or a Regulatory Capital
Event (each as defined below, and each a "Special Event") occurs, the Debenture
Issuer shall have the right (subject to the conditions set forth in the
Indenture) at any time prior to the Initial Optional Redemption Date, upon not
less than 30 nor more than 60 days notice, to redeem the Debentures in whole,
but not in part, within the 90 days following the occurrence of such Special
Event (the "90 Day Period"), and, simultaneous with such redemption, to cause a
Like Amount of the Securities to be redeemed by the Trust at the Special Event
Redemption Price on a Pro Rata basis.

                 "Tax Event" shall occur upon receipt by the Debenture Issuer
and the Trust of an opinion (a "Tax Event Opinion") of a nationally recognized
tax counsel experienced in such matters to the effect that, as a result of any
amendment to, or change





                                     I-5
<PAGE>   87

(including any announced prospective 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 pronouncement or
decision is announced on or after March 25, 1997 there is more than an
insubstantial risk that (i) the Trust 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 Debentures, (ii) interest payable by the
Debenture Issuer on the Debentures is not, or within 90 days of the date of
such opinion, will not be, deductible by the Debenture Issuer, in whole or in
part, for United States federal income tax purposes, or (iii) the Trust 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.

                 "Regulatory Capital Event" shall mean that the Debenture
Issuer shall have received an opinion of independent bank regulatory counsel
experienced in such matters to the effect that, as a result of (a) any
amendment to, or change (including any announced prospective change) in, the
laws (or any regulations thereunder) of the United States or any rules,
guidelines or policies of the Federal Reserve Board or (b) any official
administrative pronouncement or judicial decision interpreting or applying such
laws or regulations, which amendment or change is effective or such
pronouncement or decision is announced on or after March 25, 1997 the Capital
Securities do not constitute, or within 90 days of the date thereof, will not
constitute, Tier 1 Capital (or its then equivalent); provided, however, that
the distribution of the Debentures in connection with the liquidation of the
Trust by the Debenture Issuer shall not in and of itself constitute a
Regulatory Capital Event unless such liquidation shall have occurred in
connection with a Tax Event.

                 "Special Event Redemption Price" shall mean, with respect to a
redemption of Securities, a price equal to the greater of (i) 100% of the
principal of a Like Amount of Debentures to be redeemed or (ii) the sum, as
determined by a Quotation Agent (as defined in the Indenture), of the present
values of the principal amount and premium payable with respect to an optional
redemption of a Like Amount of the Debentures on the Initial Optional
Redemption Date, together with scheduled payments of interest on the Debentures
from the redemption date to and including the Initial Optional Redemption Date,
discounted to the redemption date on a semi-annual basis (assuming a 360-day
year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as
defined in the Indenture), plus, in either case, accumulated and unpaid
Distributions thereon, if any, to the date of such redemption.





                                     I-6
<PAGE>   88

                 (d)      On and from the date fixed by the Administrative 
Trustees for any distribution of Debentures and liquidation of the Trust:  (i)
the Securities will no longer be deemed to be outstanding, (ii) the Clearing 
Agency or its nominee (or any successor Clearing Agency or its nominee), as 
the Holder of the Capital Securities, will receive a registered global 
certificate or certificates representing the Debentures to be delivered upon 
such distribution and any certificates representing Securities not held by the
Clearing Agency or its nominee (or any successor Clearing Agency or its 
nominee) will be deemed to represent beneficial interests in a Like Amount of 
Debentures until such certificates are presented to the Debenture Issuer or 
its agent for transfer or reissue.

                 (e)      The Trust may not redeem fewer than all the
outstanding Securities unless all accumulated and unpaid Distributions have
been paid on all Securities for all semi-annual Distribution periods
terminating on or before the date of redemption.

                 (f)      The procedure with respect to redemptions or
distributions of Debentures shall be as follows:

                 (i)  Notice of any redemption of, or notice of distribution of
         Debentures in exchange for, the Securities (a "Redemption/Distribution
         Notice") will be given by the Trust by mail to each Holder to be
         redeemed or exchanged not fewer than 30 nor more than 60 days before
         the date fixed for redemption or exchange thereof which, in the case
         of a redemption, will be the date fixed for redemption of the
         Debentures.  For purposes of the calculation of the date of redemption
         or exchange and the dates on which notices are given pursuant to this
         Section 4(f)(i), a Redemption/ Distribution Notice shall be deemed to
         be given on the day such notice is first mailed by first-class mail,
         postage prepaid, to Holders.  Each Redemption/Distribution Notice
         shall be addressed to the Holders at the address of each such Holder
         appearing in the books and records of the Trust.  No defect in the
         Redemption/Distribution Notice or in the mailing of either thereof
         with respect to any Holder shall affect the validity of the redemption
         or exchange proceedings with respect to any other Holder.

                 (ii)  In the event that fewer than all the outstanding
         Securities are to be redeemed, the particular Securities to be
         redeemed shall be selected on a pro rata basis or by lot or by any
         other method utilized by the Property Trustee not more than 60 days
         prior to the date fixed for redemption from the outstanding Capital
         Securities not previously called for redemption, provided, however,
         that if at the time of redemption the Securities are registered as a
         Global Security, the Depository shall determine, in accordance with





                                     I-7
<PAGE>   89

         its procedures, the principal amount of such securities held for the
         account of its participants to be redeemed.

                 (iii)  If Securities are to be redeemed and the Trust gives a
         Redemption/Distribution Notice, (which notice will be irrevocable),
         then (A) with respect to Capital Securities issued in book-entry form,
         by 12:00 noon, New York City time, on the redemption date, provided
         that the Debenture Issuer has paid the Property Trustee a sufficient
         amount of cash in connection with the related redemption or maturity
         of the Debentures by 10:00 a.m., New York City time, on the maturity
         date or the date of redemption, as the case requires, the Property
         Trustee will deposit irrevocably with the Clearing Agency or its
         nominee (or successor Clearing Agency or its nominee) funds sufficient
         to pay the applicable Redemption Price with respect to such Capital
         Securities and will give the Clearing Agency irrevocable instructions
         and authority to pay the Redemption Price to the relevant Clearing
         Agency Participants, and (B) with respect to Capital Securities issued
         in certificated form and Common Securities, provided that the
         Debenture Issuer has paid the Property Trustee a sufficient amount of
         cash in connection with the related redemption or maturity of the
         Debentures, the Property Trustee will pay the relevant Redemption
         Price to the Holders by check mailed to the address of the relevant
         Holder appearing on the books and records of the Trust on the
         redemption date.  If a Redemption/Distribution Notice shall have been
         given and funds deposited as required, if applicable, then immediately
         prior to the close of business on the date of such deposit, or on the
         redemption date, as applicable, Distributions will cease to accumulate
         on the Securities so called for redemption and all rights of Holders
         so called for redemption will cease, except the right of the Holders
         of such Securities to receive the Redemption Price, but without
         interest on such Redemption Price, and such Securities shall cease to
         be outstanding.

                 (iv)  Payment of accumulated and unpaid Distributions on the
         Redemption Date of the Securities will be subject to the rights of
         Holders of Securities on the close of business on a regular record
         date in respect of a Distribution Date occurring on or prior to such
         Redemption Date.

                 Neither the Administrative Trustees nor the Trust shall be
required to register or cause to be registered the transfer of (i) any
Securities beginning on the opening of business 15 days before the day of
mailing of a notice of redemption or any notice of selection of Securities for
redemption or (ii) any Securities selected for redemption except the unredeemed
portion of any Security being redeemed.  If any date fixed for redemption of
Securities is not a Business Day, then payment of the Redemption Price payable
on such date will be made on the next succeeding





                                     I-8
<PAGE>   90

day that is a Business Day (and without any interest or other payment in
respect of any such delay), except that if such next succeeding Business Day
falls in the next 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 such date fixed for redemption.  If payment of the Redemption Price in
respect of any Securities is improperly withheld or refused and not paid either
by the Property Trustee or by the Sponsor as guarantor pursuant to the relevant
Securities Guarantee, Distributions on such Securities will continue to
accumulate from the original redemption date to the actual date of payment, in
which case the actual payment date will be considered the date fixed for
redemption for purposes of calculating the Redemption Price.

                 (v)  Redemption/Distribution Notices shall be sent by the
         Property Trustee on behalf of the Trust to (A) in respect of the
         Capital Securities, the Clearing Agency or its nominee (or any
         successor Clearing Agency or its nominee) if the Global Certificates
         have been issued or, if Definitive Capital Security Certificates have
         been issued, to the Holder thereof, and (B) in respect of the Common
         Securities to the Holder thereof.

                 (vi)  Subject to the foregoing and applicable law (including,
         without limitation, United States federal securities laws and banking
         laws), provided the acquiror is not the Holder of the Common
         Securities or the obligor under the Indenture, the Sponsor or any of
         its subsidiaries may at any time and from time to time purchase
         outstanding Capital Securities by tender, in the open market or by
         private agreement.

                 5.       Voting Rights - Capital Securities.

                 (a)      Except as provided under Sections 5(b), 6(b) and 7
and as otherwise required by law and the Declaration, the Holders of the
Capital Securities will have no voting rights.

                 (b)      So long as any Debentures are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
executing any trust or power conferred on such Debenture Trustee with respect
to the Debentures, (ii) waive any past default that is waivable under Section
5.07 of the Indenture, (iii) exercise any right to rescind or annul a
declaration of acceleration of the maturity of the principal of the Debentures
or (iv) consent to any amendment, modification or termination of the Indenture
or the Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of a Majority in liquidation amount
of all outstanding Capital Securities; provided, however, that where a consent
under the Indenture would require the consent of





                                     I-9
<PAGE>   91

each holder of Debentures affected thereby, no such consent shall be given by
the Property Trustee without the prior approval of each Holder of the Capital
Securities.  The Trustees shall not revoke any action previously authorized or
approved by a vote of the Holders of the Capital Securities except by
subsequent vote of such Holders.  Subject to Section 2.7 of the Declaration,
the Property Trustee shall notify each Holder of Capital Securities of any
notice of default with respect to the Debentures.  In addition to obtaining the
foregoing approvals of such Holders of the Capital Securities, prior to taking
any of the foregoing actions, the Trustees shall obtain an opinion of counsel
experienced in such matters to the effect that the Trust will not be classified
as an association taxable as a corporation for United States federal income tax
purposes on account of such action.

                 If an Event of Default under the Declaration has occurred and
is continuing and such event is attributable to the failure of the Debenture
Issuer to pay principal of or premium, if any, or interest on the Debentures on
the due date (or in the case of redemption, on the redemption date), then a
Holder of Capital Securities may directly institute a proceeding for
enforcement of payment to such Holder of the principal of or premium, if any,
or interest on a Like Amount of Debentures (a "Direct Action") on or after the
respective due date specified in the Debentures.  In connection with such
Direct Action, the rights of the Common Securities Holder will be subrogated to
the rights of such Holder of Capital Securities to the extent of any payment
made by the Debenture Issuer to such Holder of Capital Securities in such
Direct Action.  Except as provided in the second preceding sentence and in
Section 3.8(e) of the Declaration, the Holders of Capital Securities will not
be able to exercise directly any other remedy available to the holders of the
Debentures.

                 Any approval or direction of Holders of Capital Securities may
be given at a separate meeting of Holders of Capital Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent.  The Administrative Trustees will cause a notice
of any meeting at which Holders of Capital Securities are entitled to vote, or
of any matter upon which action by written consent of such Holders is to be
taken, to be mailed to each Holder of record of Capital Securities.  Each such
notice will include a statement setting forth (i) the date of such meeting or
the date by which such action is to be taken, (ii) a description of any
resolution proposed for adoption at such meeting on which such Holders are
entitled to vote or of such matter upon which written consent is sought and
(iii) instructions for the delivery of proxies or consents.

                 No vote or consent of the Holders of the Capital Securities
will be required for the Trust to redeem and cancel





                                     I-10
<PAGE>   92

Capital Securities or to distribute the Debentures in accordance with the
Declaration and the terms of the Securities.

                 Notwithstanding that Holders of Capital Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Capital Securities that are owned by the Sponsor or any Affiliate of the
Sponsor shall not be entitled to vote or consent and shall, for purposes of
such vote or consent, be treated as if they were not outstanding.

                 6.       Voting Rights - Common Securities.

                 (a)      Except as provided under Sections 6(b), 6(c), and 7
as otherwise required by law and the Declaration, the Holders of the Common
Securities will have no voting rights.

                 (b)      Unless an Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by the holder of the Common
Securities.  If an 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 Capital
Securities.  In no event will the holders of the Capital Securities have the
right to vote to appoint, remove or replace the Administrative Trustees, which
voting rights are vested exclusively in the Sponsor as the holder of the Common
Securities.  No resignation or removal of a 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 Declaration.

                 (c)      So long as any Debentures are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
executing any trust or power conferred on such Debenture Trustee with respect
to the Debentures, (ii) waive any past default that is waivable under Section
5.07 of the Indenture, (iii) exercise any right to rescind or annul a
declaration of acceleration of the maturity of the principal of the Debentures
or (iv) consent to any amendment, modification or termination of the Indenture
or the Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of a Majority in liquidation amount
of all outstanding Common Securities; provided, however, that where a consent
under the Indenture would require the consent of each holder of Debentures
affected thereby, no such consent shall be given by the Property Trustee
without the prior approval of each Holder of the Common Securities.  The
Trustees shall not revoke any action previously authorized or approved by a
vote of the Holders of the Common Securities except by subsequent vote of such
Holders.  Subject to Section 2.7 of the Declaration, the Property Trustee shall
notify each Holder of Common Securities of





                                     I-11
<PAGE>   93

any notice of default with respect to the Debentures.  In addition to obtaining
the foregoing approvals of such Holders of the Common Securities, prior to
taking any of the foregoing actions, the Trustees shall obtain an opinion of
counsel experienced in such matters to the effect that the Trust will not be
classified as an association taxable as a corporation for United States federal
income tax purposes on account of such action.

                 If an Event of Default under the Declaration has occurred and
is continuing and such event is attributable to the failure of the Debenture
Issuer to pay principal of or premium, if any, or interest on the Debentures on
the due date (or in the case of redemption, on the redemption date), then a
Holder of Common Securities may institute a Direct Action for enforcement of
payment to such Holder of the principal of or premium, if any, or interest on a
Like Amount of Debentures on or after the respective due date specified in the
Debentures.  In connection with Direct Action, the rights of the Common
Securities Holder will be subordinated to the rights of such Holder of Capital
Securities to the extent of any payment made by the Debenture Issuer to such
Holder of Common Securities in such Direct Action.  Except as provided in the
second preceding sentence, the Holders of Common Securities will not be able to
exercise directly any other remedy available to the holders of the Debentures.

                 Any approval or direction of Holders of Common Securities may
be given at a separate meeting of Holders of Common Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent.  The Administrative Trustees will cause a notice
of any meeting at which Holders of Common Securities are entitled to vote, or
of any matter upon which action by written consent of such Holders is to be
taken, to be mailed to each Holder of record of Common Securities.  Each such
notice will include a statement setting forth (i) the date of such meeting or
the date by which such action is to be taken, (ii) a description of any
resolution proposed for adoption at such meeting on which such Holders are
entitled to vote or of such matter upon which written consent is sought and
(iii) instructions for the delivery of proxies or consents.

                 No vote or consent of the Holders of the Common Securities
will be required for the Trust to redeem and cancel Common Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                 7.       Amendments to Declaration and Indenture.

                 In addition to the requirements set out in Section 12.1 of the
Declaration, the Declaration may be amended from time to time by the Sponsor,
the Property Trustee and the Administrative Trustees, without the consent of
the Holders (i) to cure any





                                     I-12
<PAGE>   94

ambiguity, correct or supplement any provisions in the Declaration that may be
inconsistent with any other provisions, or to make any other provisions with
respect to matters or questions arising under the Declaration which shall not
be inconsistent with the other provisions of the Declaration, or (ii) to
modify, eliminate or add to any provisions of the Declaration to such extent as
shall be necessary to ensure that the Trust will be classified for United
States federal income tax purposes as a grantor trust at all times that any
Securities are outstanding or to ensure that the Trust will not be required to
register as an "Investment Company" under the Investment Company Act; provided,
however, that in the case of clause (i), such action shall not adversely affect
in any material respect the interests of any Holder, and any amendments of the
Declaration shall become effective when notice thereof is given to the Holders.
The Declaration may also be amended by the Trustees and the Sponsor with (i)
the consent of Holders representing a Majority in liquidation amount of all
outstanding Securities, and (ii) receipt by the Trustees of an Opinion of
Counsel to the effect that such amendment or the exercise of any power granted
to the Trustees in accordance with such amendment will not affect the Trust's
status as a grantor trust for United States federal income tax purposes or the
Trust's exemption from status as an Investment Company under the Investment
Company Act, provided that, without the consent of each Holder of Trust
Securities, the Declaration 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.

                 8.       Pro Rata.

                 A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each
Holder according to the aggregate liquidation amount of the Securities held by
the relevant Holder in relation to the aggregate liquidation amount of all
Securities outstanding unless, in relation to a payment, an Event of Default
under the Declaration has occurred and is continuing, in which case any funds
available to make such payment shall be paid first to each Holder of the
Capital Securities pro rata according to the aggregate liquidation amount of
Capital Securities held by the relevant Holder relative to the aggregate
liquidation amount of all Capital Securities outstanding, and only after
satisfaction of all amounts owed to the Holders of the Capital Securities, to
each Holder of Common Securities pro rata according to the aggregate
liquidation amount of Common Securities held by the relevant Holder relative to
the aggregate liquidation amount of all Common Securities outstanding.  In any
such proration, the Property Trustee may make such adjustments as may be
appropriate in order





                                     I-13
<PAGE>   95

that only Securities in authorized denominations shall be redeemed.

                 9.       Ranking.

                 The Capital Securities rank pari passu with the Common
Securities and payment thereon shall be made Pro Rata with the Common
Securities, except that, if an Event of Default under the Declaration occurs
and is continuing, no payments in respect of Distributions on, or payments upon
liquidation, redemption or otherwise with respect to, the Common Securities
shall be made until the Holders of the Capital Securities shall be paid in full
the Distributions, Redemption Price, Liquidation Distribution and other
payments to which they are entitled at such time.

                 10.      Acceptance of Securities Guarantee and Indenture.

                 Each Holder of Capital Securities and Common Securities, by
the acceptance thereof, agrees to the provisions of the Capital Securities
Guarantee and the Common Securities Guarantee, respectively, including the
subordination provisions therein and to the provisions of the Indenture.

                 11.      No Preemptive Rights.

                 The Holders shall have no preemptive rights to subscribe for
any additional securities.

                 12.      Miscellaneous.

                 These terms constitute a part of the Declaration.

                 The Sponsor will provide a copy of the Declaration, the
Capital Securities Guarantee, the Common Securities Guarantee (as may be
appropriate) and the Indenture (including any supplemental indenture) to a
Holder without charge upon written request to the Sponsor at its principal
place of business.

                         [FORM OF REVERSE OF SECURITY]

                 Distributions payable on each Capital Security will be fixed
at a rate per annum of 9.35% (the "Coupon Rate") of the liquidation amount of
$1,000 per Capital Security, such rate being the rate of interest payable on
the Debentures to be held by the Property Trustee.  Distributions in arrears
for more than one semi-annual period will bear interest thereon compounded
semi-annually at the Coupon Rate (to the extent permitted by applicable law).
Pursuant to the Registration Rights Agreement, in certain limited circumstances
the Debenture Issuer will be required to pay Liquidated Damages (as defined in
the Registration Rights Agreement) with respect to the Debentures.  The term
"Distributions", as used herein, includes such cash distributions and any such
interest and such Liquidated Damages payable unless otherwise stated.  A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Property Trustee and to the extent the Property
Trustee has funds on hand legally available therefor.

                 Distributions on the Capital Securities will be cumulative,
will accumulate from the most recent date to which Distributions have been paid
or duly provided for or, if no Distributions have been paid or duly provided
for, from March 25, 1997 and will be payable semi- annually in arrears, on June
15 and December 15 of each year, commencing on June 15, 1997, except as
otherwise described below.  Distributions will be computed on the basis of a
360-day year consisting of twelve 30-day months and, for any period less than a
full calendar month, the number of days elapsed in such month.  As long as no
Event of Default has occurred and is continuing under the Indenture, the
Debenture Issuer has the right under the Indenture to defer payments of
interest by extending the interest payment period at any time and from time to
time on the Debentures for a period not exceeding 10 consecutive calendar
semi-annual periods, including the first such semi-annual period during such
extension period (each an "Extension Period"), provided that no Extension
Period shall end on a date other than an Interest Payment Date for the
Debentures or extend beyond the Maturity Date of the Debentures.  As a
consequence of such deferral, Distributions will also be deferred.  Despite
such deferral, semi-annual Distributions will continue to accumulate with
interest thereon (to the extent permitted by applicable law, but not at a rate
exceeding the rate of interest then accruing on the Debentures) at the Coupon
Rate compounded semi-annually during any such Extension Period.  Prior to the
termination of any such Extension Period, the Debenture Issuer may further
defer payments of interest by further extending such Extension Period; provided
that such Extension Period, together with all such previous and further
extensions within such Extension Period, may not exceed 10 consecutive
semi-annual periods, including the first semi-annual period during such
Extension Period, end on a date other than an Interest Payment





                                     A1-6
<PAGE>   102

Date for the Debentures or extend beyond the Maturity Date of the Debentures.
Payments of accumulated Distributions will be payable to Holders as they appear
on the books and records of the Trust on the first record date preceding the
end of the Extension Period.  Upon the termination of any Extension Period and
the payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

                 Subject to the prior approval of the Federal Reserve Board, if
such approval is then required under applicable law or capital guidelines or
policies of the Federal Reserve Board and to certain other conditions set forth
in the Declaration and the Indenture, the Property Trustee may, at the
direction of the Sponsor, at any time liquidate the Trust and cause the
Debentures to be distributed to the holders of the Securities in liquidation of
the Trust or, simultaneous with any redemption of the Debentures, cause a Like
Amount of the Securities to be redeemed by the Trust.

                 The Capital Securities shall be redeemable as provided in the
Declaration.

federal income tax purposes, the Debentures as indebtedness and the Common
Securities as evidence of indirect beneficial ownership in the Debentures.

                         [FORM OF REVERSE OF SECURITY]

                 Distributions payable on each Common Security will be fixed at
a rate per annum of 9.35% (the "Coupon Rate") of the liquidation amount of
$1,000 per Common Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee.  Distributions in arrears for
more than one semi-annual period will bear interest thereon compounded
semi-annually at the Coupon Rate (to the extent permitted by applicable law).
Pursuant to the Registration Rights Agreement, in certain limited circumstances
the Debenture Issuer will be required to pay Liquidated Damages (as defined in
the Registration Rights Agreement) with respect to the Debentures.  The term
"Distributions", as used herein, includes such cash distributions and any such
interest and such Liquidated Damages payable unless otherwise stated.  A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Property Trustee and to the extent the Property
Trustee has funds legally available therefor.

                 Distributions on the Common Securities will be cumulative,
will accrue from the most recent date to which Distributions have been paid or
duly provided for or, if no Distributions have been paid or duly provided for,
from March 25, 1997 and will be payable semi-annually in arrears, on June 15
and December 15 of each year, commencing on June 15, 1997, except as otherwise
described below.  Distributions will be computed on the basis of a 360-day year
consisting of twelve 30-day months and, for any period less than a full
calendar month, the number of days elapsed in such month.  As long as no Event
of Default has occurred and is continuing under the Indenture, the Debenture
Issuer has the right under the Indenture to defer payments of interest by
extending the interest payment period at any time and from time to time on the
Debentures for a period not exceeding 10 consecutive calendar semi-annual
periods, including the first such semi-annual period during such extension
period (each an "Extension Period"), provided that no Extension Period shall
end on a date other than an Interest Payment Date for the Debentures or extend
beyond the Maturity Date of the Debentures.  As a consequence of such deferral,
Distributions will also be deferred.  Despite such deferral, Distributions will
continue to accumulate with interest thereon (to the extent permitted by
applicable law, but not at a rate exceeding the rate of interest then accruing
on the Debentures) at the Coupon Rate compounded semi-annually during any such
Extension Period.  Prior to the termination of any such Extension Period, the
Debenture Issuer may further defer payments of interest by further extending
such Extension Period; provided that such Extension Period, together with all
such previous and further extensions within such Exten- sion Period, may not
exceed 10 consecutive semi-annual periods, including the first semi-annual
period during such Extension Period, or end on a date other than an Interest
Payment Date for





                                     A2-4
<PAGE>   111

the Debentures or extend beyond the Maturity Date of the Debentures.  Payments
of accrued Distributions will be payable to Holders as they appear on the books
and records of the Trust on the first record date after the end of the
Extension Period.  Upon the termination of any Extension Period and the payment
of all amounts then due, the Debenture Issuer may commence a new Extension
Period, subject to the above requirements.

                 Subject to the prior approval of the Federal Reserve Board, if
such approval is then required under applicable law or capital guidelines or
policies of the Federal Reserve Board and to certain other conditions set forth
in the Declaration and the Indenture, the Property Trustee may, at the
direction of the Sponsor, at any time liquidate the Trust and cause the
Debentures to be distributed to the holders of the Securities in liquidation of
the Trust or, simultaneous with any redemption of the Debentures, cause a Like
Amount of the Securities to be redeemed by the Trust.

                 Under certain circumstances, the rights of the holders of the
Common Securities shall be subordinate to the rights of the holders of the
Capital Securities (as defined in the Declaration), as provided in the
Declaration.

                 The Common Securities shall be redeemable as provided in the
Declaration.

               SERIES B CAPITAL SECURITIES GUARANTEE AGREEMENT


                 This GUARANTEE AGREEMENT (the "Series B Capital Securities
Guarantee"), dated as of April __, 1997, is executed and delivered by AMCORE
Financial, Inc., a Nevada corporation (the "Guarantor"), and The First National
Bank of Chicago, a banking association organized under the laws of the United
States, as trustee (the "Capital Securities Guarantee Trustee"), for the
benefit of the Holders (as defined herein) from time to time of the Series B
Capital Securities (as defined herein) of AMCORE Capital Trust I, a Delaware
statutory business trust (the "Issuer").

                 WHEREAS, pursuant to an Amended and Restated Declaration of
Trust (the "Declaration"), dated as of March 25, 1997, among the trustees of
the Issuer, the Guarantor, as sponsor, and the holders from time to time of
undivided beneficial interests in the assets of the Issuer, the Issuer issued
on March 25, 1997 40,000 capital securities, having an aggregate liquidation
amount of $40,000,000, such capital securities being designated the Series A
9.35% Capital Securities (collectively the "Series A Capital Securities") and,
in connection with an Exchange Offer (as defined in the Declaration) has agreed
to execute and deliver this Series B Capital Securities Guarantee for the
benefit of holders of the Series B 9.35% Capital Securities (the "Series B
Capital Securities").

                 WHEREAS, as incentive for the Holders to exchange the Series A
Capital Securities for the Series B Capital Securities, the Guarantor desires
irrevocably and unconditionally to agree, to the extent set forth in this
Series B Capital Securities Guarantee, to pay to the Holders the Guarantee
Payments (as defined below).  The Guarantor agrees to make certain other
payments on the terms and conditions set forth herein.

                 WHEREAS, the Guarantor has executed and delivered a guarantee
agreement (the "Common Securities Guarantee"), with substantially identical
terms to this Series B Capital Securities Guarantee, for the benefit of the
holders of the Common Securities (as defined herein), except that if an Event
of Default (as defined in the Declaration) has occurred and is continuing, the
rights of holders of the Common Securities to receive Guarantee Payments under
the Common Securities Guarantee are subordinated, to the extent and in the
manner set forth herein and in the Common Securities Guarantee, to the rights
of holders of Series A Capital Securities and the Series B Capital Securities
to receive Guarantee Payments under the Series A Capital Securities Guarantee
and this Series B Capital Securities Guarantee, as the case may be.

         Guarantee Trustee or its agents alone shall be sufficient and
         effective to perform any such action.  No third party shall be
         required to inquire as to the authority of the Capital Securities
         Guarantee Trustee to so act or as to its compliance with any of the
         terms and provisions of this Series B Capital Securities Guarantee,
         both of which shall be conclusively evidenced by the Capital
         Securities Guarantee Trustee's or its agent's taking such action.

                 (x)  Whenever in the administration of this Series B Capital
         Securities Guarantee the Capital Securities Guarantee Trustee shall
         deem it desirable to receive instructions with respect to enforcing
         any remedy or right or taking any other action hereunder, the Capital
         Securities Guarantee Trustee (i) may request instructions from the
         Holders of a Majority in liquidation amount of the Series B Capital
         Securities, (ii) may refrain from enforcing such remedy or right or
         taking such other action until such instructions are received, and
         (iii) shall be protected in conclusively relying on or acting in
         accordance with such instructions.

                 (xi)  The Capital Securities Guarantee Trustee shall not be
         liable for any action taken, suffered, or omitted to be taken by it in
         good faith, without negligence, and reasonably believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Series B Capital Securities Guarantee.

                 (b)   No provision of this Series B Capital Securities
Guarantee shall be deemed to impose any duty or obligation on the Capital
Securities Guarantee Trustee to perform any act or acts or exercise any right,
power, duty or obligation conferred or imposed on it in any jurisdiction in
which it shall be illegal, or in which the Capital Securities Guarantee Trustee
shall be


                                      12

unqualified or incompetent in accordance with applicable law, to perform any
such act or acts or to exercise any such right, power, duty or obligation.  No
permissive power or authority available to the Capital Securities Guarantee
Trustee shall be construed to be a duty.

                 Securities Guarantee

Guarantee shall be taken as the statements of the Guarantor, and the Capital

Guarantor shall in all respects comply with the provisions of Section 310(b) of

SECTION 4.2      Appointment, Removal and Resignation of Capital Securities
                 Guarantee Trustee

SECTION 5.1      Guarantee

                 The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by the Issuer), as and when due, regardless of any defense,
right of set-off or counterclaim that the Issuer may have or assert.  The
Guarantor's obligation to make a Guarantee Payment may be satisfied by direct
payment of the required amounts by the Guarantor to the Holders or by causing
the Issuer to pay such amounts to the Holders.

SECTION 5.2      Waiver of Notice and Demand

                 The Guarantor hereby waives notice of acceptance of this
Series B Capital Securities Guarantee and of any liability to which it applies
or may apply, presentment, demand for payment, any right to require a
proceeding first against the Issuer or any other Person before proceeding
against the Guarantor, protest, notice of nonpayment, notice of dishonor,
notice of redemption and all other notices and demands.

SECTION 5.3      Obligations Not Affected

                 The obligations, covenants, agreements and duties of the
Guarantor under this Series B Capital Securities Guarantee shall in no way be
affected or impaired by reason of the happening from time to time of any of the
following:

                 (a)  the release or waiver, by operation of law or otherwise,
of the performance or observance by the Issuer of any express or implied
agreement, covenant, term or condition relating to the Series B Capital 
Securities to be performed or observed by the Issuer; 
        
                 (b)  the extension of time for the payment by the Issuer
of all or any portion of the Distributions, Redemption Price, Liquidation
Distribution or any other sums payable under the terms of the Series B Capital
Securities or the extension of time for the performance of any other obligation
under, arising out of, or in connection with, the Series B Capital Securities
(other than an extension of time for payment of Distributions, Redemption
Price, Liquidation Distribution or other sum payable that results from the
extension of any interest payment period on the Debentures permitted by the
Indenture);

                 (c)  any failure, omission, delay or lack of diligence on
the part of the Holders to enforce, assert or exercise any right, privilege,
power or remedy conferred on the Holders pursuant to the terms of the Series B
Capital Securities, or any


                                      15

<PAGE>   19

action on the part of the Issuer granting indulgence or extension of any kind;

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

                 (e)  any invalidity of, or defect or deficiency in, the
Series B Capital Securities;

                 (f)  the settlement or compromise of any obligation
guaranteed hereby or hereby incurred; or

                 (g)  any other circumstance whatsoever that might
otherwise constitute a legal or equitable discharge or defense of a guarantor,
it being the intent of this Section 5.3 that the obligations of the Guarantor
with respect to the Guarantee Payments shall be absolute and unconditional
under any and all circumstances.

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

SECTION 5.4      Rights of Holders

                 (a)  The Holders of a Majority in liquidation amount of
the Series B Capital Securities have the right to direct the time, method and
place of conducting any proceeding for any remedy available to the Capital
Securities Guarantee Trustee in respect of this Series B Capital Securities
Guarantee or exercising any trust or power conferred upon the Capital
Securities Guarantee Trustee under this Series B Capital Securities Guarantee;
provided, however, that, subject to Section 3.1, the Capital Securities
Guarantee Trustee shall have the right to decline to follow any such direction
if the Capital Securities Guarantee Trustee shall determine that the action so
directed would be unjustly prejudicial to the holders not taking part in such
direction or if the Capital Securities Guarantee Trustee being advised by
counsel determines that the action or proceeding so directed may not lawfully
be taken or if the Capital Securities Guarantee Trustee in good faith by its
board of directors or trustees, executive committee, or a trust committee of
directors or trustees and/or Responsible Officers shall determine that the
action or proceedings so directed would involve the Capital Securities
Guarantee Trustee in personal liability.

                 (b)  If the Capital Securities Guarantee Trustee fails to
enforce such Series B Capital Securities Guarantee, any Holder


                                      16



<PAGE>   20

may institute a legal proceeding directly against the Guarantor to enforce the
Capital Securities Guarantee Trustee's rights under this Series B Capital
Securities Guarantee, without first instituting a legal proceeding against the
Issuer, the Capital Securities Guarantee Trustee or any other person or entity.
The Guarantor waives any right or remedy to require that any action be brought
first against the Issuer or any other person or entity before proceeding
directly against the Guarantor.

SECTION 5.5      Guarantee of Payment

                 This Series B Capital Securities Guarantee creates a guarantee
of payment and not of collection.

SECTION 5.6      Subrogation

                 The Guarantor shall be subrogated to all (if any) rights of
the Holders against the Issuer in respect of any amounts paid to such Holders
by the Guarantor under this Series B Capital Securities Guarantee; provided,
however, that the Guarantor shall not (except to the extent required by
mandatory provisions of law) be entitled to enforce or exercise any right that
it may acquire by way of subrogation or any indemnity, reimbursement or other
agreement, in all cases as a result of payment under this Series B Capital
Securities Guarantee, if, at the time of any such payment, any amounts are due
and unpaid under this Series B Capital Securities Guarantee.  If any amount
shall be paid to the Guarantor in violation of the preceding sentence, the
Guarantor agrees to hold such amount in trust for the Holders and to pay over
such amount to the Holders.

SECTION 5.7      Independent Obligations

                 The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Series B
Capital Securities, and that the Guarantor shall be liable as principal and as
debtor hereunder to make Guarantee Payments pursuant to the terms of this
Series B Capital Securities Guarantee notwithstanding the occurrence of any
event referred to in subsections (a) through (h), inclusive, of Section 5.3
hereof.

unsecured obligation of the Guarantor and will rank (i) subordinate and junior
in right of payment to Senior Indebtedness (as defined in the Indenture), to
the same extent and in the same manner that the Debentures are subordinated to

Guarantee.

Trust shall, for the benefit of the Holders, at the Company's   cost, use its
best efforts to (i) cause to be filed with the SEC within 150 days after the
Issue Date an Exchange Offer Registration Statement on an appropriate form

Offer Registration Statement to be declared effective under the Securities Act
by the SEC not later than the date which is 180 days after the Issue Date, and
(iii) keep such Exchange Offer Registration Statement effective for not less
than 30 calendar days (or longer if required by applicable law) after the date
notice of the Exchange Offer is mailed to the Holders.  Upon the effectiveness

promptly commence the Exchange Offer, it being the objective of such Exchange
Offer to enable each Holder eligible and electing to exchange Registrable
Securities for a like principal amount of Exchange Debentures or a like
liquidation amount of Exchange Capital Securities, together with the Exchange
Guarantee, as applicable (assuming that such Holder is not an affiliate of the
Company within the meaning of Rule 405 under the Securities Act and is not a
broker-dealer tendering Registrable Securities acquired directly from the
Company for its own account, acquires the Exchange Securities in the ordinary
course of such Holder's business and has no arrangements or understandings with
any Person to participate in the Exchange Offer for the purpose of distributing
the Exchange Securities) to transfer such Exchange Securities from and after
their receipt without any limitations or restrictions under the Securities Act
and under state securities or blue sky laws.

          In connection with the Exchange Offer, the Company and the
Trust shall:

     (i)  mail to each Holder a copy of the Prospectus forming part of the
Exchange Offer Registration Statement, together with an appropriate letter of
transmittal and related documents;


     (ii)  keep the Exchange Offer open for acceptance for a period of not
less than 30 days after the date notice thereof is mailed to the Holders (or
longer if required by applicable law) (such period referred to herein as the
"Exchange Period");





                                      7
<PAGE>   8

     (iii) utilize the services of the Depositary for the Exchange Offer;

     (iv)  permit Holders to withdraw tendered Securities at any time prior to
the close of business, New York time, on the last Business Day of the Exchange
Period, by sending to the institution specified in the notice, a telegram, 
telex, facsimile transmission or letter setting forth the name of such Holder,
the principal amount of Securities delivered for exchange, and a statement that
such Holder is withdrawing his election to have such Securities exchanged;

     (v)  notify each Holder that any Security not tendered by such Holder
in the Exchange Offer will remain outstanding and continue to accrue interest
or accumulate distributions, as the case may be, but will not retain any rights
under this Agreement (except in the case of the Initial Purchasers and
Participating Broker-Dealers as provided herein); and

     (vi)  otherwise comply in all respects with all applicable laws
relating to the Exchange Offer.

          If any Initial Purchaser determines upon advice of its outside 
counsel that it is not eligible to participate in the Exchange Offer with
respect to the exchange of Securities constituting any portion of an unsold
allotment in the initial distribution, as soon as practicable upon receipt by
the Company and the Trust of a written request from such Initial Purchaser, the
Company and the Trust, as applicable, shall issue and deliver to such Initial
Purchaser in exchange (the "Private Exchange") for the Securities held by such
Initial Purchaser, a like liquidation amount of Capital Securities of the
Trust, together with the Exchange Guarantee, or a like principal amount of the
Subordinated Debentures of the Company, as applicable, that are identical
(except that such securities may bear a customary legend with respect to
restrictions on transfer pursuant to the Securities Act) to the Exchange
Securities (the "Private Exchange Securities") and which are issued pursuant to
the Indenture, the Declaration or the Guarantee (which provides that the
Exchange Securities will not be subject to the transfer restrictions set forth
in the Indenture or the Declaration, as applicable, and that the Exchange
Securities, the Private Exchange Securities and the Securities will vote and
consent together on all matters as one class and that neither the Exchange
Securities, the Private Exchange Securities nor the Securities will have the
right to vote or consent as a separate class on any matter).  The Private
Exchange Securities shall be of the same series as the Exchange Securities and
the Company and the Trust will seek to cause the CUSIP Service Bureau to issue
the same CUSIP Numbers for the Private Exchange Securities as for the Exchange
Securities issued pursuant to the Exchange Offer.





                                      8
<PAGE>   9

          As soon as practicable after the close of the Exchange Offer and, if
applicable, the Private Exchange, the Company and the Trust, as the case 
requires, shall:

     (i)  accept for exchange all Securities or portions thereof tendered
and not validly withdrawn pursuant to the Exchange Offer or the Private
Exchange;

     (ii)  deliver, or cause to be delivered, to the applicable Trustee for
cancellation all Securities or portions thereof so accepted for exchange by the
Company; and

     (iii)  issue, and cause the applicable Trustee under the Indenture,
the Declaration or the Guarantee, as applicable, to promptly authenticate and
deliver to each Holder, new Exchange Securities or Private Exchange Securities,
as applicable, equal in principal amount to the principal amount of the
Subordinated Debentures or equal in liquidation amount to the liquidation
amount to the Capital Securities (together with the guarantee thereof) as are
surrendered by such Holder.

          Distributions on each Exchange Capital Security and interest
on each Exchange Debenture and Private Exchange Security issued pursuant to the
Exchange Offer and in the Private Exchange will accrue from the last date on
which a Distribution or interest was paid on the Capital Security or the
Subordinated Debenture surrendered in exchange therefor or, if no Distribution
or interest has been paid on such Capital Security or Subordinated Debenture,
from the Issue Date.  To the extent not prohibited by any law or applicable
interpretation of the staff of the SEC, the Company and the Trust shall use
their best efforts to complete the Exchange Offer as provided above, and shall
comply with the applicable requirements of the Securities Act, the Exchange Act
and other applicable laws in connection with the Exchange Offer.  The Exchange
Offer shall not be subject to any conditions, other than that the Exchange
Offer does not violate applicable law or any applicable interpretation of the
staff of the SEC.  Each Holder of Registrable Securities who wishes to exchange
such Registrable Securities for Exchange Securities in the Exchange Offer will
be required to make certain customary representations in connection therewith,
including, in the case of any Holder of Capital Securities, representations
that (i) it is not an affiliate of the Trust or the Company, (ii) the Exchange
Securities to be received by it were acquired in the ordinary course of its
business and (iii) at the time of the Exchange Offer, it has no arrangement
with any person to participate in the distribution (within the meaning of the
Securities Act) of the Exchange Capital Securities.  The Company and the Trust
shall inform the Initial Purchasers, after consultation with the Trustee, of
the names and addresses of the Holders to whom the Exchange Offer is made, and
the Initial Purchasers shall have the right to contact such Holders and





                                      9
<PAGE>   10

otherwise facilitate the tender of Registrable Securities in the Exchange
Offer.

          Upon consummation of the Exchange Offer in accordance with this 
Section 2(a), the provisions of this Agreement shall continue to apply,
mutatis mutandis, solely with respect to  Registrable Securities that are
Private Exchange Securities and Exchange Securities held by Participating
Broker-Dealers, and the Company and the Trust shall have no further obligation
to register the Registrable Securities (other than Private Exchange Securities)
pursuant to Section 2(b) of this Agreement.

          (b)  Shelf Registration.  In the event that (i) the Company, the 
Trust or the Majority Holders reasonably determine, after conferring with
counsel (which may be in-house counsel), that the Exchange Offer Registration
provided in Section 2(a) above is not available because of any change in law or
in currently prevailing interpretations of the staff of the SEC, (ii) the
Company shall determine in good faith that there is a reasonable likelihood
that, or a material uncertainty exists as to whether consummation of the
Exchange Offer would result in a material adverse tax consequence to the
Company, (iii) the Exchange Offer Registration Statement is not declared
effective within 180 days of the Issue Date or (iv) upon the request of any
Initial Purchaser with respect to any Registrable Securities held by it, if
such Initial Purchaser is not permitted, in the reasonable opinion of Barack
Ferrazzano Kirschbaum Perlman & Nagelberg, pursuant to applicable law or
applicable interpretations of the staff of the SEC, to participate in the
Exchange Offer and thereby receive securities that are freely tradeable without
restriction under the Securities Act and applicable blue sky or state
securities laws (any of the events specified in (i)- (iv) being a "Shelf
Registration Event" and the date of occurrence thereof, the "Shelf Registration
Event Date"), the Company and the Trust shall, at their cost, use their best
efforts to cause to be filed as promptly as practicable after such Shelf
Registration Event Date, as the case may be, and, in any event, within 45 days
after such Shelf Registration Event Date (which shall be no earlier than 75
days after the Closing Time), a Shelf Registration Statement providing for the
sale by the Holders of all of the Registrable Securities, and shall use its
best efforts to have such Shelf Registration Statement declared effective by
the SEC as soon as practicable.  No Holder of Registrable Securities shall be
entitled to include any of its Registrable Securities in any Shelf Registration
pursuant to this Agreement unless and until such Holder agrees in writing to be
bound by all of the provisions of this Agreement applicable to such Holder and
furnishes to the Company and the Trust in writing, within 15 days after receipt
of a request therefor, such information as the Company and the Trust may, after
conferring with counsel with regard to information relating to Holders that
would be required by the SEC to be included in such Shelf Registration
Statement or Prospectus included therein, reasonably request for





                                     10
<PAGE>   11

inclusion in any Shelf Registration Statement or Prospectus included therein.
Each Holder as to which any Shelf Registration is being effected agrees to
furnish to the Company and the Trust all information with respect to such
Holder necessary to make the information previously furnished to the Company by
such Holder not materially misleading.

          The Company and the Trust agree to use their best efforts to
keep the Shelf Registration Statement continuously effective for the Rule
144(k) Period or for 180 days in the case of a Shelf Registration Statement
filed pursuant to Section 2(b)(iv) (subject in each case to extension pursuant
to the last paragraph of Section 3 hereof) or for such shorter period which
will terminate when all of the Registrable Securities covered by the Shelf
Registration Statement have been sold pursuant to the Shelf Registration
Statement or cease to be outstanding (the "Effectiveness Period").  The Company
and the Trust shall not permit any securities other than Registrable Securities
to be included in the Shelf Registration.  The Company and the Trust will, in
the event a Shelf Registration Statement is declared effective, provide to each
Holder a reasonable number of copies of the Prospectus which is a part of the
Shelf Registration Statement, notify each such Holder when the Shelf
Registration has become effective and use its best efforts to take certain
other actions as are required to permit certain unrestricted resales of the
Registrable Securities.  The Company and the Trust further agree, if necessary,
to supplement or amend the Shelf Registration Statement, if required by the
rules, regulations or instructions applicable to the registration form used by
the Company for such Shelf Registration Statement or by the Securities Act or
by any other rules and regulations thereunder for shelf registrations, and the
Company and the Trust agree to furnish to the Holders of Registrable Securities
copies of any such supplement or amendment promptly after its being used or
filed with the SEC.

          (c)  Expenses.  The Company, as issuer of the Junior Subordinated 
Debentures, shall pay all Registration Expenses in connection with any 
Registration Statement filed pursuant to Section 2(a) or 2(b) hereof and
will reimburse the Initial Purchasers for the reasonable fees and disbursements
of Barack Ferrazzano Kirschbaum Perlman & Nagelberg counsel for the Initial
Purchasers, incurred in connection with the Exchange Offer and, if applicable,
the Private Exchange, and one counsel designated in writing by the Majority
Holders to act as counsel for the Holders of the Registrable Securities in
connection with a Shelf Registration Statement, which other counsel shall be
reasonably satisfactory to the Company.  Except as provided herein, each Holder
shall pay all expenses of its counsel, underwriting discounts and commissions
and transfer taxes, if any, relating to the sale or disposition of such
Holder's Registrable Securities pursuant to the Shelf Registration Statement.





                                     11
<PAGE>   12

          (d)  Effective Registration Statement.  An Exchange Offer
Registration Statement pursuant to Section 2(a) hereof or a Shelf Registration
Statement pursuant to Section 2(b) hereof will not be deemed to have become
effective unless it has been declared effective by the SEC; provided, however,
that if, after it has been declared effective, the offering of Registrable
Securities pursuant to such Exchange Offer Registration Statement or Shelf
Registration Statement is interfered with by any stop order, injunction or
other order or requirement of the SEC or any other governmental agency or
court, such Registration Statement will be deemed not to have been effective
during the period of such interference, until the offering of Registrable
Securities pursuant to such Registration Statement may legally resume.  The
Company and the Trust will be deemed not to have used their best efforts to
cause the Exchange Offer Registration Statement or the Shelf Registration
Statement, as the case may be, to become, or to remain, effective during the
requisite period if either of them voluntarily take any action that would
result in any such Registration Statement not being declared effective or in
the Holders of Registrable Securities covered thereby not being able to
exchange or offer and sell such Registrable Securities during that period
unless such action is required by applicable law.

          (e)  Liquidated Damages.  In the event that (i) neither the Exchange
Offer Registration Statement is filed with the SEC on or prior to the 150th day
after the Issue Date nor a Shelf Registration Statement is filed with the SEC
on or prior to the 45th day after the Shelf Registration Event Date, then 
commencing on the day after the applicable required filing date, additional 
interest shall accrue on the principal amount of the Subordinated Debentures,

Trust Securities (as such term is defined in the Declaration), each at a rate 
of 0.25% per annum; or

          (ii)    neither the Exchange Offer Registration Statement nor a Shelf
Registration Statement is declared effective by the SEC on or prior to the
180th day after the Issue Date (in the case of an Exchange Offer Registration
Statement) on or prior to the later of the 30th day after the date such Shelf
Registration Statement was required to be filed and the 180th day after the

Registration Statement) or the later of the 31st day after the date such Shelf
Registration Statement was required to be filed and the 181st day after the
Issue Date (in the case of a Shelf Registration Statement), additional interest
shall accrue on the principal amount of the Subordinated Debentures, and

          (iii) (A) the Trust has not exchanged Exchange Capital Securities for
all Capital Securities or the Company has not exchanged Exchange Guarantees or
Exchange Subordinated Debentures for all Guarantees or Subordinated Debentures
validly tendered, in accordance with the terms of the Exchange Offer on or
prior to the 45th day after the date on which the Exchange Offer Registration
Statement was declared effective or (B) if applicable, the Shelf Registration
Statement has been declared effective and such Shelf Registration Statement
ceases to be effective at any time prior to the expiration of the Rule 144(k)
Period (other than after such time as all Capital Securities have been disposed
of thereunder or otherwise cease to be Registrable Securities), then additional
interest shall accrue on the principal amount of Subordinated Debentures, and
additional distributions shall accumulate on the liquidation amount of the
Trust Securities, each at a rate of 0.25% per annum commencing on (x) the 46th
day after such effective date, in the case of (A) above, or (y) the day such
Shelf Registration Statement ceases to be effective in the case of (B) above;

provided, however, that neither the additional interest rate on the
Subordinated Debentures, nor the additional distribution rate on the
liquidation amount of the Trust Securities, may exceed in the aggregate 0.25%
per annum; provided, further, however, that (1) upon the filing of the Exchange
Offer Registration Statement or a Shelf Registration Statement (in the case of
clause (i) above), (2) upon the effectiveness of the Exchange Offer
Registration Statement or a Shelf Registration Statement (in the case of clause
(ii) above), or (3) upon the exchange of Exchange Capital Securities, Exchange
Guarantees and Exchange Subordinated Debentures for all Capital Securities,
Guarantees and Subordinated Debentures tendered (in the case of clause (iii)(A)
above), or upon the effectiveness of the Shelf Registration Statement which had
ceased to remain effective (in the case of clause (iii)(B) above), additional
interest on the Subordinated Debentures, and additional distributions on the
liquidation amount of the Trust Securities as a result of such clause (or the
relevant subclause thereof), as the case may be, shall cease to accrue or
accumulate, as the case may be.

          Any amounts of additional interest and additional Distributions due
pursuant to Section 2(e)(i), (ii) or (iii) above ("Liquidated Damages") will be
payable in cash on the next succeeding June 15 or December 15, as the case may
be, to holders of the Trust Securities on the relevant record dates for the
payment of interest and Distributions pursuant to the Indenture and the
Declaration, respectively.

               (f)  Specific Enforcement.  Without limiting the remedies
available to the Holders, the Company and the Trust acknowledge that any
failure by the Company or the Trust to comply with its obligations under
Section 2(a) and Section 2(b) hereof may result in material irreparable injury
to the Holders for which there is no adequate remedy at law, that it would not
be possible to measure





                                     13
<PAGE>   14

damages for such injuries precisely and that, in the event of any such failure,
any Holder may obtain such relief as may be required to specifically enforce
the Company's and the Trust's obligations under Section 2(a) and Section 2(b)
hereof.

          3.   Registration Procedures.  In connection with the
obligations of the Company and the Trust with respect to the Registration
Statements pursuant to Sections 2(a) and 2(b) hereof, the Company and the Trust
shall use their best efforts to:

          (a)  prepare and file with the SEC a Registration Statement or
     Registration Statements as prescribed by Sections 2(a) and 2(b) hereof     
     within the relevant time period specified in Section 2 hereof on the
     appropriate form under the Securities Act, which form (i) shall be
     selected by the Company and the Trust, (ii) shall, in the case of a Shelf
     Registration, be available for the sale of the Registrable Securities by
     the selling Holders thereof and, in the case of an Exchange Offer, be
     available for the exchange of Registrable Securities, and (iii) shall
     comply as to form in all material respects with the requirements of the
     applicable form and include all financial statements required by the SEC
     to be filed therewith; and use its best efforts to cause such Registration
     Statement to become effective and remain effective in accordance with
     Section 2 hereof; provided, however, that if (1) such filing is pursuant
     to Section 2(b), or (2) a Prospectus contained in an Exchange Offer
     Registration Statement filed pursuant to Section 2(a) is required to be
     delivered under the Securities Act by any Participating Broker-Dealer who
     seeks to sell Exchange Securities, before filing any Registration
     Statement or Prospectus or any amendments or supplements thereto, the
     Company and the Trust shall furnish to and afford the Holders of the
     Registrable Securities and each such Participating Broker-Dealer, as the
     case may be, covered by such Registration Statement, their counsel and the
     managing underwriters, if any, a reasonable opportunity to review copies
     of all such documents (including copies of any documents to be
     incorporated by reference therein and all exhibits thereto) proposed to be
     filed.  The Company and the Trust shall not file any Registration
     Statement or Prospectus or any amendments or supplements thereto in
     respect of which the Holders must be afforded an opportunity to review
     prior to the filing of such document if the Majority Holders or such
     Participating Broker-Dealer, as the case may be, their counsel or the
     managing underwriters, if any, shall reasonably object;

          (b)  prepare and file with the SEC such amendments and
     post-effective amendments to each Registration Statement as may be 
     necessary to keep such Registration Statement effective for the
     Effectiveness Period or the Applicable Period, as the case may be; and
     cause each Prospectus to be supplemented, if so determined by the Company
     or the Trust or requested by the





                                     14
<PAGE>   15

     SEC, by any required prospectus supplement and as so supplemented to be
     filed pursuant to Rule 424 (or any similar provision then in force)        
     under the Securities Act, and comply with the provisions of the Securities
     Act, the Exchange Act and the rules and regulations promulgated thereunder
     applicable to it with respect to the disposition of all securities covered
     by each Registration Statement during the Effectiveness Period or the
     Applicable Period, as the case may be, in accordance with the intended
     method or methods of distribution by the selling Holders thereof described
     in this Agreement (including sales by any Participating Broker-Dealer);

          (c)  in the case of a Shelf Registration, (i) notify each
     Holder of Registrable Securities included in the Shelf Registration        
     Statement, at least three Business Days prior to filing, that a Shelf
     Registration Statement with respect to the Registrable Securities is being
     filed and advising such Holder that the distribution of Registrable
     Securities will be made in accordance with the method selected by the
     Majority Holders; and (ii) furnish to each Holder of Registrable
     Securities included in the Shelf Registration State- ment and to each
     underwriter of an underwritten offering of Registrable Securities, if any,
     without charge, as many copies of each Prospectus, including each
     preliminary Prospectus, and any amendment or supplement thereto and such
     other documents as such Holder or underwriter may reasonably request, in
     order to facilitate the public sale or other disposition of the
     Registrable Securities; and (iii) consent to the use of the Prospectus or
     any amendment or supplement thereto by each of the selling Holders of
     Registrable Secu- rities included in the Shelf Registration Statement in
     connection with the offering and sale of the Registrable Securities
     covered by the Prospectus or any amendment or supplement thereto;

          (d)  in the case of a Shelf Registration, use its best efforts
     to register or qualify the Registrable Securities under all applicable
     state securities or "blue sky" laws of such jurisdictions by the time      
     the applicable Registration Statement is declared effective by the SEC as
     any Holder of Registrable Securities covered by a Registration Statement
     and each underwriter of an underwritten offering of Registrable Securities
     shall reasonably request in writing in advance of such date of
     effectiveness, and do any and all other acts and things which may be
     reasonably necessary or advisable to enable such Holder and underwriter to
     consummate the disposition in each such jurisdiction of such Registrable
     Securities owned by such Holder; provided, however, that the Company and
     the Trust shall not be required to (i) qualify as a foreign corporation or
     as a dealer in securities in any jurisdiction where it would not otherwise
     be required to qualify but for this Section 3(d), (ii) file any general
     consent to service of process in any jurisdiction where it would not
     otherwise be





                                     15
<PAGE>   16

     subject to such service of process or (iii) subject itself to taxation
     in any such jurisdiction if it is not then so subject;

          (e)  in the case of (1) a Shelf Registration or (2) Participating 
     Broker-Dealers from whom the Company or the Trust has received prior
     written notice that they will be utilizing the Prospectus contained in
     the Exchange Offer Registration Statement as provided in Section 3(t)
     hereof, are seeking to sell Exchange Securities and are required to
     deliver Prospectuses, notify each Holder of Registrable Securities, or
     such Participating Broker-Dealers, as the case may be, their counsel and
     the managing underwriters, if any, promptly and promptly confirm such
     notice in writing (i) when a Registration Statement has become effective
     and when any post- effective amendments and supplements thereto become
     effective, (ii) of any request by the SEC or any state securities
     authority for amendments and supplements to a Registration Statement or
     Prospectus or for additional information after the Registration Statement
     has become effective, (iii) of the issuance by the SEC or any state
     securities authority of any stop order suspending the effectiveness of a
     Registration Statement or the qualification of the Registrable Securities
     or the Exchange Securities to be offered or sold by any Participating
     Broker-Dealer in any jurisdiction described in paragraph 3(d) hereof or
     the initiation of any proceedings for that purpose, (iv) in the case of a
     Shelf Registration, if, between the effective date of a Registration
     Statement and the closing of any sale of Registrable Securities covered
     thereby, the representations and warranties of the Company and the Trust
     contained in any purchase agreement, securities sales agreement or other
     similar agreement, if any cease to be true and correct in all material
     respects, and (v) of the happening of any event or the failure of any
     event to occur or the discovery of any facts or otherwise, during the
     Effectiveness Period which makes any statement made in such Registration
     Statement or the related Prospectus untrue in any material respect or
     which causes such Registration Statement or Prospectus to omit to state a
     material fact necessary to make the statements therein, in the light of
     the circumstances under which they were made, not misleading, and (vi) the
     Company and the Trust's reasonable determination that a post-effective
     amendment to the Registration Statement would be appropriate;

          (f)  make every reasonable effort to obtain the withdrawal of
     any order suspending the effectiveness of a Registration Statement at      
     the earliest possible moment;

          (g)  in the case of a Shelf Registration, furnish to each Holder of 
     Registrable Securities included within the coverage of such Shelf 
     Registration Statement, without charge, at least

     Registration and any post-effective amendment thereto (without documents
     incorporated therein by reference or exhibits thereto, unless requested);

     the closing of any sale of Registrable Securities pursuant to such Shelf
     Registration Statement;

          (i)  in the case of a Shelf Registration or an Exchange Offer

     Securities, such Prospectus will not contain any untrue statement of a
     material fact or omit to state a material fact necessary to make the
     statements therein, in the light of the circumstances under which they
     were made, not misleading; and to notify each Holder to suspend use of the
     Prospectus as promptly as practicable after the occurrence of such an
     event, and each Holder hereby agrees to suspend use of the Prospectus
     until the Company has amended or supplemented the Prospectus to correct
     such misstatement or omission;

          (j)  in the case of a Shelf Registration, a reasonable time

     jurisdiction or is necessary in connection with any action, suit or

     of such inspections shall be deemed confidential and shall not be used by
     it as the basis for any market transactions in the securities of the Trust
     or the Company unless and until such is made generally available to the
     public.  Each selling Holder of such Registrable Securities and each such
     Participating Broker-Dealer will be required to further agree in writing
     that it will, upon learning that disclosure of such Records is sought in a
     court of competent jurisdiction, give notice to the Company and allow the

     the end of any 12-month period if such period is a fiscal year) (i)
     commencing at the end of any fiscal quarter in which Registrable
     Securities are sold to underwriters in a firm commitment or best efforts
     underwritten offering and (ii) if not sold to underwriters in such an
     offering, commencing on the first day of the first fiscal quarter of the
     Company after the effective date of a Registration Statement, which
     statements shall cover said 12-month periods; provided, that the Company's
     obligations under this paragraph (o) shall be satisfied by the timely
     filing of its quarterly and annual reports on Forms 10-Q and 10- K;

          (p)  upon consummation of an Exchange Offer or a Private
     Exchange, if requested by a Trustee, obtain an opinion of counsel to       
     the Company addressed to the Trustee for the benefit of all Holders of
     Registrable Securities participating in the Exchange Offer or the Private
     Exchange, as the case may be, and which includes an opinion that (i) the
     Company and the Trust, as the case requires, have duly authorized,
     executed and delivered the Exchange Securities and Private Exchange
     Securities, and (ii) each of the Exchange Securities or the Private
     Exchange Securities, as the case may be, constitute a legal, valid and
     binding obligation of the Company or the Trust, as the case requires,

     exceptions);

          (q)  if an Exchange Offer or a Private Exchange is to be
     consummated, upon delivery of the Registrable Securities by Holders to     
     the Company or the Trust, as applicable (or to such other Person as
     directed by the Company or the Trust, respectively), in exchange for the
     Exchange Securities or the Private Exchange Securities, as the case may
     be, the Company or the Trust, as applicable, shall mark, or cause to be
     marked, on such Registrable Securities delivered by such Holders that such
     Registrable Securities are being cancelled in exchange for the Exchange
     Securities or the Private Exchange Securities, as the case may be; in no
     event shall such Registrable Securities be marked as paid or otherwise
     satisfied;

          (r)  cooperate with each seller of Registrable Securities
     covered by any Registration Statement and each underwriter, if any,

     section entitled "Plan of Distribution," which section shall be reasonably
     acceptable to the Initial Purchasers or another representative of the
     Participating Broker-Dealers, and which shall contain a summary statement
     of the positions taken or policies made by the staff of the SEC with
     respect to the potential "underwriter" status of any broker-dealer (a
     "Participating Broker-Dealer") that holds Registrable Securities acquired
     for its own account as a result of market-making activities or other
     trading activities and that will be the beneficial owner (as defined in
     Rule 13d-3 under the Exchange Act) of Exchange Securities to be received
     by such broker- dealer in the Exchange Offer, whether such positions or
     policies have been publicly disseminated by the staff of the SEC or such
     positions or policies, in the reasonable judgment of the Initial
     Purchasers or such other representative, represent the prevailing views of
     the staff of the SEC, including a statement that any such broker-dealer
     who receives Exchange Securities for Registrable Securities pursuant to
     the Exchange Offer may be deemed a statutory underwriter and must deliver
     a prospectus meeting the requirements of the Securities Act in connection
     with any resale of such Exchange Securities, (ii) furnish to each
     Participating Broker-Dealer who has delivered to the Company the notice
     referred to in Section 3(e), without charge, as many copies of each
     Prospectus included in the Exchange Offer Registration Statement,
     including any preliminary prospectus, and any





                                     21
<PAGE>   22

     amendment or supplement thereto, as such Participating Broker-Dealer may
     reasonably request (each of the Company and the Trust hereby       
     consents to the use of the Prospectus forming part of the Exchange Offer
     Registration Statement or any amendment or supplement thereto by any
     Person subject to the prospectus delivery requirements of the Securities
     Act, including all Participating Broker-Dealers, in connection with the
     sale or transfer of the Exchange Securities covered by the Prospectus or
     any amendment or supplement thereto), (iii) use its best efforts to keep
     the Exchange Offer Registration Statement effective and to amend and
     supplement the Prospectus contained therein in order to permit such
     Prospectus to be lawfully delivered by all Persons subject to the
     prospectus delivery requirements of the Securities Act for such period of
     time as such Persons must comply with such requirements under the
     Securities Act and applicable rules and regulations in order to resell the
     Exchange Securities; provided, however, that such period shall not be
     required to exceed 90 days (or such longer period if extended pursuant to
     the last sentence of Section 3 hereof) (the "Applicable Period"), and (iv)
     include in the transmittal letter or similar documentation to be executed
     by an exchange offeree in order to participate in the Exchange Offer (x)
     the following provision:

          "If the exchange offeree is a broker-dealer holding Registrable
          Securities acquired for its own account as a  result of market-making
          activities or other trading activities, it will deliver a prospectus
          meeting the re- quirements of the Securities Act in connection with
          any resale of Exchange Securities received in respect of such
          Registrable Securities pursuant to the Exchange Offer";

and (y) a statement to the effect that by a broker-dealer making the
acknowledgment described in clause (x) and by delivering a Prospectus in
connection with the exchange of Registrable Securities, the broker-dealer will
not be deemed to admit that it is an underwriter within the meaning of the
Securities Act; and

          (B)      in the case of any Exchange Offer Registration
     Statement, the Company and the Trust agree to deliver to the Initial       
     Purchasers or to another representative of the Participating
     Broker-Dealers, if requested by any such Initial Purchasers or such other
     representative of the Participating Broker-Dealers, on behalf of the
     Participating Broker-Dealers upon  consummation of the Exchange Offer (i)
     an opinion of counsel in form and substance reasonably satisfactory to the
     Initial Purchasers or such other representative of the Participating
     Broker-Dealers, covering the matters customarily covered in opinions
     requested in connection with Exchange Offer Registration Statements and
     such other matters as may be





                                     22
<PAGE>   23

     reasonably requested (it being agreed that the matters to be covered by
     such opinion may be subject to customary qualifications and        
     exceptions), (ii) an officers' certificate containing certifications
     substantially similar to those set forth in Section 5(g) of the Purchase
     Agreement and such additional certifications as are customarily delivered
     in a public offering of debt securities and (iii) as well as upon the
     effectiveness of the Exchange Offer Registration Statement, a comfort
     letter, in each case, in customary form if permitted by Statement on
     Auditing Standards No. 72.

          The Company or the Trust may require each seller of Registrable 
Securities as to which any registration is being effected to furnish to the
Company or the Trust, as applicable, such information regarding such seller as
may be required by the staff of the SEC to be included in a Registration
Statement.  The Company or the Trust may exclude from such registration the
Registrable Securities of any seller who unreasonably fails to furnish such
information within a reasonable time after receiving such request. The Company
shall have no obligation to register under the Securities Act the Registrable
Securities of a seller who so fails to furnish such information.

          In the case of (1) a Shelf Registration Statement or (2)
Participating Broker-Dealers who have notified the Company and the Trust that
they will be utilizing the Prospectus contained in the Exchange Offer
Registration Statement as provided in Section 3(t) hereof, are seeking to sell
Exchange Securities and are required to deliver Prospectuses each Holder agrees
that, upon receipt of any notice from the Company or the Trust of the happening
of any event of the kind described in Section 3(e)(ii), 3(e)(iii), 3(e)(v) or
3(e)(vi) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 3(i) hereof or until it is advised in writing (the "Advice") by the
Company and the Trust that the use of the applicable Prospectus may be resumed,
and, if so directed by the Company and the Trust, such Holder will deliver to
the Company or the Trust (at the Company's or the Trust's expense, as the case
requires) all copies in such Holder's possession, other than permanent file
copies then in such Holder's possession, of the Prospectus covering such
Registrable Securities or Exchange Securities, as the case may be, current at
the time of receipt of such notice.  If the Company or the Trust shall give any
such notice to suspend the disposition of Registrable Securities or Exchange
Securities, as the case may be, pursuant to a Registration Statement, the
Company and the Trust shall use their best efforts to file and have declared
effective (if an amendment) as soon as practicable an amendment or supplement
to the Registration Statement and shall extend the period during which such
Registration Statement shall be maintained effective pursuant to this Agreement
by the number of days in the period from





                                     23
<PAGE>   24

and including the date of the giving of such notice to and including the date
when the Company and the Trust shall have made available to the Holders (x)
copies of the supplemented or amended Prospectus necessary to resume such
dispositions or (y) the Advice.

          4.       Indemnification and Contribution.  (a) In connection
with any Registration Statement, the Company and the Trust shall, jointly and
severally, indemnify and hold harmless each Initial Purchaser, each Holder,
each underwriter who participates in an offering of the Registrable Securities,
each Participating Broker-Dealer, each Person, if any, who controls any of such
parties within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act and each of their respective directors, officers, employees
and agents, as follows:

          (i)  from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, as incurred, arising out of any
     untrue statement or alleged untrue statement of a material fact contained
     in any Registration Statement (or any amendment thereto), covering
     Registrable Securities or Exchange Securities, including all documents
     incorporated therein by reference, or the omission or alleged omission
     therefrom of a material fact required to be stated therein or necessary to
     make the statements therein not misleading or arising out of any untrue
     statement or alleged untrue statement of a material fact contained in any
     Prospectus (or any amendment or supplement thereto) or the omission or
     alleged omission therefrom of a material fact necessary in order to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading;

          (ii)  from and against any and all loss, liability, claim, damage and
     expense whatsoever, joint or several, as incurred, to the extent of the
     aggregate amount paid in  settlement of any litigation,    or any
     investigation or proceeding by any court or governmental agency or body,
     commenced or threatened, or of any claim whatsoever based upon any such
     untrue statement or omission, or any such alleged untrue statement or
     omission, if such settlement is effected with the prior written consent of
     the Company; and

          (iii)  from and against any and all expenses whatsoever, as incurred
     (including reasonable fees and disbursements of counsel chosen by such
     Holder, such Participating Broker-Dealer, or any underwriter (except to
     the extent otherwise expressly provided in Section 4(c) hereof)),
     reasonably incurred in investigating, preparing or defending against any
     litigation, or any investigation or proceeding by any court or
     governmental agency or body, commenced or threatened, or any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, to





                                     24
<PAGE>   25

     the extent that any such expense is not paid under subparagraph (i) or
     (ii) of this Section 4(a);

provided, however, that (i) this indemnity does not apply to any loss,
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished in writing to the
Company or the Trust by such Holder, such Participating Broker-Dealer or any
underwriter with respect to such Holder, Participating Broker-Dealer or any
underwriter, as the case may be, expressly for use in a Registration Statement
(or any amendment thereto) or any Prospectus (or any amendment or supplement
thereto) and (ii) the Company and the Trust shall not be liable to any such
Holder, Participating Broker-Dealer, any underwriter or controlling person,
with respect to any untrue statement or alleged untrue statement or omission or
alleged omission in any preliminary Prospectus to the extent that any such
loss, liability, claim, damage or expense of any Holder, Participating
Broker-Dealer, any underwriter or controlling person results from the fact that
such Holder, any underwriter or Participating Broker-Dealer sold Securities to
a person to whom there was not sent or given, at or prior to the written
confirmation of such sale, a copy of the final Prospectus as then amended or
supplemented if the Company had previously furnished copies thereof to such
Holder, underwriter or Participating Broker-Dealer and the loss, liability,
claim, damage or expense of such Holder, underwriter, Participating
Broker-Dealer or controlling person results from an untrue statement or
omission of a material fact contained in the preliminary Prospectus which was
corrected in the final Prospectus.  Any amounts advanced by the Company or the
Trust to an indemnified party pursuant to this Section 4 as a result of such
losses shall be returned to the Company or the Trust if it shall be finally
determined by such a court in a judgment not subject to appeal or final review
that such indemnified party was not entitled to indemnification by the Company
or the Trust.

          (b)  Each Holder agrees, severally and not jointly, to indemnify and
hold harmless the Company, the Trust, any underwriter and the other selling
Holders and each of their respective directors, officers (including each
officer of the Company and the Trust who signed the Registration Statement),
employees and agents and each Person, if any, who controls the Company, the
Trust, any underwriter or any other selling Holder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act, from and
against any and all loss, liability, claim, damage and expense whatsoever
described in the indemnity contained in Section 4(a) hereof, as incurred, but
only with respect to untrue statements or omissions, or alleged untrue
statements or omissions, made in a Registration Statement (or any amendment
thereto) or any Prospectus (or any amendment or supplement thereto) in reliance
upon and in conformity with written information furnished to the Company or the
Trust by such selling Holder with respect to such





                                     25
<PAGE>   26

Holder expressly for use in a Registration Statement (or any amendment
thereto), or any such Prospectus (or any amendment or supplement thereto);
provided, however, that, in the case of Shelf Registration Statement, no such
Holder shall be liable for any claims hereunder in excess of the amount of net
proceeds received by such Holder from the sale of Registrable Securities
pursuant to such Shelf Registration Statement.

          (c)  Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, enclosing a copy of all papers properly
served on such indemnified party, but failure to so notify an indemnifying
party shall not relieve such indemnifying party from any liability which it may
have under this Section 4, except to the extent that it is materially
prejudiced by such failure.  An indemnifying party may participate at its own
expense in the defense of such action.  If an indemnifying party so elects
within a reasonable time after receipt of such notice, an indemnifying party,
severally or jointly with any other indemnifying parties receiving such notice,
may assume the defense of such action with counsel chosen by it and reasonably
acceptable to the indemnified parties defendant in such action, provided,
however, that if (i) representation of such indemnified party by the same
counsel would present a conflict of interest or (ii) the actual or potential
defendants in, or targets of, any such action include both the indemnified
party and the indemnifying party and any such indemnified party reasonably
determines that there may be legal defenses available to such indemnified party
which are different from or in addition to those available to such indemnifying
party, then in the case of clauses (i) and (ii) of this Section 4(c) such
indemnifying party and counsel for each indemnifying party or parties shall not
be entitled to assume such defense.  If an indemnifying party is not entitled
to assume the defense of such action as a result of the proviso to the
preceding sentence, counsel for such indemnifying party and counsel for each
indemnified party or parties shall be entitled to conduct the defense of such
indemnified party or parties.  If an indemnifying party assumes the defense of
such action, in accordance with and as permitted by the provisions of this
paragraph, such indemnifying parties shall not be liable for any fees and
expenses of counsel for the indemnified parties incurred thereafter in
connection with such action.  In no event shall the indemnifying parties be
liable for the fees and expenses of more than one counsel (in addition to local
counsel), separate from its own counsel, for all indemnified parties in
connection with any one action or separate but similar or related actions in
the same jurisdiction arising out of the same general allegations or
circumstances.  No indemnifying party shall, without the prior written consent
of the indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribu-





                                     26
<PAGE>   27

tion could be sought under this Section 4 (whether or not the indemnified
parties are actual or potential parties thereto), unless such settlement,
compromise or consent (i) includes an unconditional written release in form and
substance satisfactory to the indemnified parties of each indemnified party
from all liability arising out of such litigation, investigation, proceeding or
claim and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

          (d)  Notwithstanding the last sentence of Section 4(c), if at any 
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for reasonable fees and expenses of counsel
pursuant to Section 4(a)(iii) above, such indemnifying party agrees that it
shall be liable for any settlement effected without its written consent if (i)
such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
have received notice of the terms of such settlement at least 30 days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement; provided that an indemnifying party shall not be
liable for any such settlement effected without its consent if such
indemnifying party (1) reimburses such indemnified party in accordance with
such request to the extent it considers reasonable and (2) provides written
notice to the indemnified party substantiating the unpaid balance as
unreasonable, in each case prior to the date of such settlement.

          (e)  In order to provide for just and equitable contribution in 
circumstances under which any of the indemnity provisions set forth in this
Section 4 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company, the Trust, and
the Holders shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement
incurred by the Company, the Trust, and the Holders, as incurred; provided that
no Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any Person that
was not guilty of such fraudulent misrepresentation.  As between the Company,
the Trust, and the Holders, such parties shall contribute to such aggregate
losses, liabilities, claims, damages and expenses of the nature contemplated by
such indemnity agreement in such proportion as shall be appropriate to reflect
the relative fault of the Company and Trust, on the one hand, and the Holders,
on the other hand, with respect to the statements or omissions which resulted
in such loss, liability, claim, damage or expense, or action in respect
thereof, as well as any other relevant equitable considerations.  The relative
fault of the Company and the Trust, on the one hand, and of the Holders, on the
other hand, shall be deter-





                                     27
<PAGE>   28

mined by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or the Trust, on
the one hand, or by or on behalf of the Holders, on the other, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.  The Company, the Trust and the Holders of
the Registrable Securities agree that it would not be just and equitable if
contribution pursuant to this Section 4 were to be determined by pro rata
allocation or by any other method of allocation that does not take into account
the relevant equitable considerations.  For purposes of this Section 4, each
affiliate of a Holder, and each director, officer, employee, agent and Person,
if any, who controls a Holder or such affiliate within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act shall have the same
rights to contribution as such Holder, and each director of each of the Company
or the Trust, each officer of each of the Company or the Trust who signed the
Registration Statement, and each Person, if any, who controls each of the
Company and the Trust within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act shall have the same rights to contribution as
each of the Company or the Trust.

          5.       Participation in an Underwritten Registration.  No
Holder may participate in an underwritten registration hereunder unless such
Holder (a) agrees to sell such Holder's Registrable Securities on the basis
provided in the underwriting arrangement approved by the Persons entitled
hereunder to approve such arrangements and (b) completes and executes all
reasonable questionnaires, powers of attorney, indemnities, underwriting
agreements, lock-up letters and other documents reasonably required under the
terms of such underwriting arrangements.

          6.       Selection of Underwriters.  The Holders of
Registrable Securities covered by the Shelf Registration Statement who desire
to do so may sell the securities covered by such Shelf Registration in one
underwritten offering.  In such underwritten offering, the underwriter or
underwriters and manager or managers that will administer the offering will be
selected by the Holders of a majority in aggregate principal amount of the
Registrable Securities included in such offering; provided, however, that such
underwriters and managers must be reasonably satisfactory to the Company and
the Trust and further, that the Company shall be obligated to effect only one
underwritten offering of the Registrable Securities covered by such Shelf
Registration Statement.

          7.       Miscellaneous.

          (a)  Rule 144 and Rule 144A.  For so long as the Company or
the Trust is subject to the reporting requirements of Section 13 or 15 of the
Exchange Act and any Registrable Securities remain outstanding, the Company and
the Trust, as the case may be, will





                                     28
<PAGE>   29

their its best efforts to file the reports required to be filed by it under the
Securities Act and Section 13(a) or 15(d) of the Exchange Act and the rules and
regulations adopted by the SEC thereunder, that if it ceases to be so required
to file such reports, it will, upon the request of any Holder of Registrable
Securities (a) make publicly available such information as is necessary to
permit sales of their securities pursuant to Rule 144 under the Securities Act,
(b) deliver such information to a prospective purchaser as is necessary to
permit sales of their securities pursuant to Rule 144A under the Securities Act
and it will take such further action as any Holder of Registrable Securities
may reasonably request, and (c) take such further action that is reasonable in
the circumstances, in each case, to the extent required from time to time to
enable such Holder to sell its Registrable Securities without registration
under the Securities Act within the limitation of the exemptions provided by
(i) Rule 144 under the Securities Act, as such rule may be amended from time to
time, (ii) Rule 144A under the Securities Act, as such rule may be amended from
time to time, or (iii) any similar rules or regulations hereafter adopted by
the SEC.  Upon the request of any Holder of Registrable Securities, the Company
and the Trust will deliver to such Holder a written statement as to whether it
has complied with such requirements.

          (b)  No Inconsistent Agreements.  The Company or the Trust has
not entered into nor will the Company or the Trust on or after the date of this
Agreement enter into any agreement which is inconsistent with the rights
granted to the Holders of Registrable Securities in this Agreement or otherwise
conflicts with the provisions hereof.  The rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of the Company's or the Trust's other issued and
outstanding securities under any such agreements.

          (c)  Amendments and Waivers.  The provisions of this
Agreement, including the provisions of this sentence, may not be amended,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given unless the Company and the Trust has
obtained the written consent of Holders of at least a majority in aggregate
principal amount of the outstanding Registrable Securities affected by such
amendment, modification, supplement, waiver or departure; provided no
amendment, modification or supplement or waiver or consent to the departure
with respect to the provisions of Section 4 hereof shall be effective as
against any Holder of Registrable Securities unless consented to in writing by
such Holder of Registrable Securities.  Notwithstanding the foregoing sentence,
(i) this Agreement may be amended, without the consent of any Holder of
Registrable Securities, by written agreement signed by the Company, the Trust
and the Initial Purchaser, to cure any ambiguity, correct or supplement any
provision of this Agreement that may be inconsistent with any other provision
of this Agreement or to make any other provisions with





                                     29
<PAGE>   30

respect to matters or questions arising under this Agreement which shall not be
inconsistent with other provisions of this Agreement, (ii) this Agreement may
be amended, modified or supplemented, and waivers and consents to departures
from the provisions hereof may be given, by written agreement signed by the
Company, the Trust and the Initial Purchaser to the extent that any such
amendment, modification, supplement, waiver or consent is, in their reasonable
judgment, necessary or appropriate to comply with applicable law (including any
interpretation of the Staff of the SEC) or any change therein and (iii) to the
extent any provision of this Agreement relates to the Initial Purchasers, such
provision may be amended, modified or supplemented, and waivers or consents to
departures from such provisions may be given, by written agreement signed by
the Initial Purchaser, the Company and the Trust.

          (d)  Notices.  All notices and other communications provided
for or permitted hereunder shall be made in writing by hand- delivery,
registered first-class mail, telex, telecopier, or any courier guaranteeing
overnight delivery (i) if to a Holder, at the most current address given by
such Holder to the Company or the Trust by means of a notice given in
accordance with the provisions of this Section 7(d), which address initially
is, with respect to the Initial Purchasers, the address set forth in the
Purchase Agreement; and (ii) if to the Company or the Trust, initially at the
Company's address set forth in the Purchase Agreement and thereafter at such
other address, notice of which is given in accordance with the provisions of
this Section 7(d).

          All such notices and communications shall be deemed to have
been duly given: at the time delivered by hand, if personally delivered; five
Business Days after being deposited in the mail, postage prepaid, if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied;
and on the next Business Day, if timely delivered to an air courier
guaranteeing overnight delivery.

          Copies of all such notices, demands, or other communications
shall be concurrently delivered by the Person giving the same to the Trustee,
at the address specified in the Indenture.

          (e)  Successors and Assigns.  This Agreement shall inure to the 
benefit of and be binding upon the successors, assigns and transferees of the 
Initial Purchasers, including, without limitation and without the need for
an express assignment, subsequent Holders; provided, however, that nothing
herein shall be deemed to permit any assignment, transfer or other disposition
of Registrable Securities in violation of the terms of the Purchase Agreement
or the Indenture.  If any transferee of any Holder shall acquire Registrable
Securities, in any manner, whether by operation of law or otherwise, such
Registrable Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable Securities, such Person
shall be conclusively deemed to





                                     30
<PAGE>   31

have agreed to be bound by and to perform all of the terms and provisions of
this Agreement and such Person shall be entitled to receive the benefits
hereof.

          (f)  Third Party Beneficiary.  Each of the Initial Purchasers shall 
be a third party beneficiary of the agreements made hereunder between the
Company and the Trust, on the one hand, and the Holders, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights or the rights of
Holders hereunder.

          (g)  Counterparts.  This Agreement may be executed in any number of 
counterparts and by the parties hereto in separate counterparts, each of which
 when so executed shall be deemed to be an original and all of which taken 
together shall constitute one and the same agreement.

          (h)  Headings.  The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

          (i)  GOVERNING LAW.  THIS AGREEMENT SHALL BE DEEMED TO HAVE
BEEN MADE IN THE STATE OF NEW YORK.  THE VALIDITY AND INTERPRETATION OF THIS
AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
GIVING EFFECT TO ANY PROVISIONS RELATING TO CONFLICTS OF LAWS.  EACH OF THE
PARTIES HERETO AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE
OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT.

          (j)  Severability.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the
remaining provisions contained herein shall not be affected or impaired
thereby.

          (k)  Securities Held by the Company, the Trust or its
Affiliates.  Whenever the consent or approval of Holders of a specified
percentage of Registrable Securities is required hereunder, Registrable
Securities held by the Company, the Trust or its affiliates (as such term is
defined in Rule 405 under the Securities Act) shall not be counted in
determining whether such consent or approval was given by the Holders of such
required percentage.

                 IN WITNESS WHEREOF, the parties have executed this Agreement
as of the date first written above.
