     In addition, two banks have subsidiaries that provide insurance and
investment brokerage services, and we have a subsidiary that provides data
processing services to the three banks operating within the Chicago metropolitan
area.

     At March 31, 2000, we had $1.3 billion in assets, $690.9 million in loans,
$985.9 million in deposits and $68.5 million in stockholders' equity. Our first
quarter 2000 net income was $3.4 million, an increase of 34.9% over net income
of $2.5 million for the quarter ended March 31, 1999. Basic and diluted earnings
per share were $0.31 for the quarter ended March 31, 2000, compared to $0.23 for
the similar period in 1999. Our return on average assets was 1.07% for the first
quarter of 2000, up from 0.95% for the same period of 1999, while our return on
average equity increased to 20.86% for the first quarter 2000 from 13.44% for
the prior year period.

     Our common stock is quoted on the Nasdaq National Market under the symbol
MBHI. Our executive offices are located at 501 W. North Avenue, Melrose Park, IL
60160 and our telephone number is (708) 865-1053.

     We have accomplished significant profitable growth within our markets over
the past ten years. Total assets have increased from $341.5 million at December
31, 1989 to $1.3 billion at December 31, 1999, while net income has increased
from $2.5 million for 1989 to $11.9 million for 1999. We attribute this success
to our selective banking center expansion and our strategy to be positioned as a
lower cost provider of premium rate deposits and competitively priced loan
products within our core markets. The rate of

     Our strategy is to continue to take advantage of opportunities to expand
our business through internal growth as well as possible branch acquisitions,
while maintaining our historically low net overhead ratio. We are seeking to
increase loans as a percentage of total earning assets and to leverage our
customer base by increasing our emphasis on fee-based products and services. Key
aspects of our growth strategy include:

     - Increasing loan growth and net interest margins by leveraging our
       expertise and strong commercial customer base;

     - Building a well-defined sales and service culture to maximize revenues
       per household and ensure the highest levels of customer service;

     - Improving our overall revenue effectiveness and cost-efficiency,
       streamlining decision-making and further centralizing and standardizing
       critical support activities;

     - Accelerating fee income growth from nonbank financial
       services -- primarily insurance and investment brokerage; and

     - Expanding our market position through the opening of new banking centers
       and the highly selective acquisition of other banks and branches.

     As part of our expansion strategy, we opened new banking centers in
McHenry, Island Lake, and Roselle, Illinois during the past 18 months, and
acquired a banking center in Aledo, Illinois in December 1999. Also in 1999, we
began a strategic repositioning to eliminate unprofitable operations, to enhance
our revenues while managing our costs more effectively, and to realign certain
management responsibilities to develop an orderly succession plan and streamline
decision-making. To support our growth, over the last year we have added a
senior credit officer, several experienced loan officers, a sales manager, two
experienced banking center managers, an investment portfolio manager and a
training officer.

                               on March 31, June 30, September 30 and December
                               31 of each year beginning September 30, 2000. As
                               long as the preferred securities are represented
                               by a global security, the record date for
                               distributions on the preferred securities will be
                               the business day prior to the distribution date.
                               We may defer the payment of cash distributions,
                               as described below.

When the preferred securities
must be redeemed.............  The debentures will mature and the preferred
                               securities must be redeemed on             ,
                               2030. We have the option, however, to shorten the
                               maturity date to a date not earlier than
                                           , 2005. We will not shorten the
                               maturity date unless we have received the prior
                               approval of the Board of Governors of the Federal
                               Reserve System, if required.

Redemption of the preferred
securities before
               , 2030 is
possible.....................  The trust must redeem the preferred securities
                               when the debentures are paid at maturity or upon
                               any earlier redemption of the debentures. We may
                               redeem all or part of the debentures at any time
                               on or after             , 2005. In addition, we
                               may redeem, at any time, all of the debentures
                               if:

                                  - the interest we pay on the debentures is no
                                    longer deductible by us for federal tax
                                    purposes; or the trust becomes subject to
                                    federal income tax; or the trust becomes or
                                    will become subject to certain other taxes
                                    or governmental charges;

                                  - there is a change in existing laws or
                                    regulations that requires the trust to
                                    register as an investment company; or

                                  - there is a change in the capital adequacy
                                    guidelines of the Federal Reserve that
                                    results in the preferred securities not
                                    being counted as Tier 1 capital.

                               We may also redeem debentures at any time, and
                               from time to time, in an amount equal to the
                               liquidation amount of any preferred securities we
                               repurchase, plus a proportionate amount of common
                               securities, but only in exchange for a like
                               amount of the preferred securities and common
                               securities then owned by us.

                               Redemption of the debentures prior to maturity
                               will be subject to the prior approval of the
                               Federal Reserve, if approval is then required. If
                               your preferred securities are redeemed by the
                               trust, you will receive the liquidation amount of
                               $25 per preferred security plus any accrued and
                               unpaid distributions to the date of redemption.

We have the option to extend
the interest payment
period.......................  The trust will rely solely on payments made by us
                               under the debentures to pay distributions on the
                               preferred securities. As long as we are not in
                               default under the indenture relating to the
                               debentures, we may, at one or more times, defer
                               interest payments on the debentures for up to 20
                               consecutive quarters, but not beyond
                                           , 2030. If we defer interest payments
                               on the debentures:

                                  - the trust will also defer distributions on
                                    the preferred securities;

                                  - the distributions you are entitled to will
                                    accumulate; and

                                  - these accumulated distributions will earn
                                    additional interest at an annual rate of
                                         %, compounded quarterly. At the end of
                                    any deferral period, we will pay to the
                                    trust all accrued and unpaid interest under
                                    the debentures. The trust will then pay all
                                    accumulated and unpaid distributions to you.

You will still be taxed if
distributions on the
preferred securities are
deferred.....................  If a deferral of payment occurs, you will still
                               be required to recognize the deferred amounts as
                               income for United States federal income tax
                               purposes in advance of receiving these amounts,
                               even if you are a cash basis taxpayer.

Our guarantee of payment.....  We guarantee the trust will use its assets to pay
                               the distributions on the preferred securities and
                               the liquidation amount upon liquidation of the
                               trust. However, the guarantee does not apply when
                               the trust does not have sufficient funds to make
                               the payments. If we do not make payments on the
                               debentures, the trust will not have sufficient
                               funds to make payments on the preferred
                               securities. In this event, your remedy is to
                               institute a legal proceeding directly against us
                               for enforcement of payments under the debentures.

We may distribute the
debentures directly to you...  We may, at any time, dissolve the trust and
                               distribute the debentures to you, subject to the
                               prior approval of the Federal Reserve, if
                               required. If we distribute the debentures, we
                               will use our reasonable efforts to list them on a
                               national securities exchange or comparable
                               automated quotation system.

How the securities will rank
in right of payment..........  Our obligations under the preferred securities,
                               debentures and guarantee are unsecured and will
                               rank as follows with regard to right of payment:

                                  - the preferred securities will rank equally
                                    with the common securities of the trust. The
                                    trust will pay distributions on the
                                    preferred securities and the common
                                    securities pro rata. However, if we default
                                    with respect to the debentures, then no
                                    distributions on the common securities of
                                    the trust or our

                                        4
<PAGE>   10

                                   common stock will be paid until all
                                   accumulated and unpaid distributions on the
                                   preferred securities have been paid;

                                  - our obligations under the debentures and the
                                    guarantee are unsecured and generally will
                                    rank junior in priority to our existing and
                                    future senior and other subordinated
                                    indebtedness; and

                                  - because we are a bank holding company, the
                                    junior subordinated debentures and the
                                    guarantee will effectively be subordinated
                                    to all depositors' claims, as well as
                                    existing and future liabilities of our
                                    subsidiaries.

Voting rights of the
preferred securities.........  Except in limited circumstances, holders of the
                               preferred securities will have no voting rights.

You will not receive
certificates.................  The preferred securities will be represented by a
                               global security that will be deposited with and
                               registered in the name of The Depository Trust
                               Company, New York, New York, or its nominee. This
                               means that you will not receive a certificate for
                               the preferred securities, and your beneficial
                               ownership interests will be recorded through the
                               DTC book-entry system.

How the proceeds of this
offering will be used........  The trust will invest all of the proceeds from
                               the sale of the preferred securities in the
                               debentures. We estimate that the net proceeds to
                               us from the sale of the debentures to the trust,
                               after deducting underwriting expenses and
                               commissions, will be approximately $23.9 million.
                               We expect to use approximately $12.3 million of
                               the net proceeds from the sale of the debentures
                               to repay all of the indebtedness currently
                               outstanding under our revolving credit line. We
                               also anticipate that upon completion of this
                               offering we will contribute approximately $9.0
                               million of the net proceeds to our banks as
                               capital to support their internal growth. The
                               remaining net proceeds will be available to us
                               for general corporate purposes, including, but
                               not limited to, additional capital contributions
                               to the banks to support future growth and to
                               finance potential future expansion. Pending
                               allocation of these remaining proceeds to
                               specific uses, the funds may be invested in
                               marketable securities.

     Before purchasing the preferred securities being offered, you should
carefully consider the "Risk Factors" beginning on page 7.

                                  RISK FACTORS

     An investment in the preferred securities involves a number of risks. We
urge you to read all of the information contained in this prospectus. In
addition, we urge you to consider carefully the following factors in evaluating
an investment in the trust before you purchase the preferred securities offered
by this prospectus.

     Because the trust will rely on the payments it receives on the debentures
to fund all payments on the preferred securities, and because the trust may
distribute the debentures in exchange for the preferred securities, purchasers
of the preferred securities are making an investment decision that relates to
the debentures being issued by Midwest Banc Holdings as well as the preferred
securities. Purchasers should carefully review the information in this
prospectus about the preferred securities, the debentures and the guarantee.

           RISKS RELATED TO AN INVESTMENT IN THE PREFERRED SECURITIES

IF WE DO NOT MAKE INTEREST PAYMENTS UNDER THE DEBENTURES, THE TRUST WILL BE
UNABLE TO PAY DISTRIBUTIONS AND LIQUIDATION AMOUNTS. THE GUARANTEE WILL NOT
APPLY BECAUSE THE GUARANTEE COVERS PAYMENTS ONLY IF THE TRUST HAS FUNDS
AVAILABLE.

     The trust will depend solely on our payments on the debentures to pay
amounts due to you on the preferred securities. If we default on our obligation
to pay the principal or interest on the debentures, the trust will not have
sufficient funds to pay distributions or the liquidation amount on the preferred
securities. In that case, you will not be able to rely on the guarantee for
payment of these amounts because the guarantee only applies if the trust has
sufficient funds to make distributions on or to pay the liquidation amount of
the preferred securities. Instead, you or the property trustee will have to
institute a direct action against us to enforce the property trustee's rights
under the indenture relating to the debentures.

TO THE EXTENT WE MUST RELY ON DIVIDENDS FROM OUR SUBSIDIARIES TO MAKE INTEREST
PAYMENTS ON THE DEBENTURES TO THE TRUST, OUR AVAILABLE CASH FLOW MAY BE
RESTRICTED.

     We are a holding company and substantially all of our assets are held by
our subsidiaries. Our ability to make payments on the debentures when due will
depend primarily on available cash resources at the bank holding company and
dividends from our subsidiaries. Dividend payments or extensions of credit from
our banking subsidiaries are subject to regulatory limitations, generally based
on capital levels and current and retained earnings, imposed by the various
regulatory agencies with authority over such subsidiaries. The ability of each
banking subsidiary to pay dividends is also subject to its profitability,
financial condition, capital expenditures and other cash flow requirements. We
cannot assure you that our subsidiaries will be able to pay dividends in the
future.

THE DEBENTURES AND THE GUARANTEE RANK LOWER THAN OUR OTHER INDEBTEDNESS AND OUR
HOLDING COMPANY STRUCTURE EFFECTIVELY SUBORDINATES ANY CLAIMS AGAINST US TO
THOSE OF OUR SUBSIDIARIES' CREDITORS.

     Our obligations under the debentures and the guarantee are unsecured and
will rank junior in priority of payment to our existing and future senior and
subordinated indebtedness, which totaled $269.0 million at March 31, 2000. The
issuance of the debentures and the preferred securities does not limit our
ability or the ability of our subsidiaries to incur additional indebtedness,
guarantees or other liabilities.

     Because we are a holding company, the creditors of our subsidiaries,
including depositors, also will have priority over you in any distribution of
our subsidiaries' assets in liquidation, reorganization or otherwise.
Accordingly, the debentures and the guarantee will be effectively subordinated
to all existing and future liabilities of our subsidiaries, and you should look
only to our assets for payments on the preferred securities and the debentures.

                                        7
<PAGE>   13

WE HAVE THE OPTION TO DEFER INTEREST PAYMENTS ON THE DEBENTURES FOR SUBSTANTIAL
PERIODS.

     We may, at one or more times, defer interest payments on the debentures for
up to 20 consecutive quarters. If we defer interest payments on the debentures,
the trust will defer distributions on the preferred securities during any
deferral period. During a deferral period, you will be required to recognize as
income for federal income tax purposes the amount approximately equal to the
interest that accrues on your proportionate share of the debentures held by the
trust in the tax year in which that interest accrues, even though you will not
receive these amounts until a later date.

     You will also not receive the cash related to any accrued and unpaid
interest from the trust if you sell the preferred securities before the end of
any deferral period. During a deferral period, accrued but unpaid distributions
will increase your tax basis in the preferred securities. If you sell the
preferred securities during a deferral period, your increased tax basis will
decrease the amount of any capital gain or increase the amount of any capital
loss that you may have otherwise realized on the sale. A capital loss, except in
certain limited circumstances, cannot be applied to offset ordinary income. As a
result, deferral of distributions could result in ordinary income, and a related
tax liability for the holder, and a capital loss that may only be used to offset
a capital gain.

     We do not currently intend to exercise our right to defer interest payments
on the debentures. However, if we exercise our right in the future, the market
price of the preferred securities would likely be adversely affected. The
preferred securities may trade at a price that does not fully reflect the value
of accrued but unpaid interest on the debentures. If you sell the preferred
securities during an interest deferral period, you may not receive the same
return on investment as someone who continues to hold the preferred securities.
Due to our right to defer interest payments, the market price of the preferred
securities may be more volatile than the market prices of other securities
without the deferral feature.

WE HAVE MADE ONLY LIMITED COVENANTS IN THE INDENTURE AND THE TRUST AGREEMENT.

     The indenture governing the debentures and the trust agreement governing
the trust do not require us to maintain any financial ratios or specified levels
of net worth, revenues, income, cash flow or liquidity, and therefore do not
protect holders of the debentures or the preferred securities in the event we
experience significant adverse changes in our financial condition or results of
operations. In addition, neither the indenture nor the trust agreement limits
our ability or the ability of any subsidiary to incur additional indebtedness.
Therefore, you should not consider the provisions of these governing instruments
as a significant factor in evaluating whether we will be able to comply with our
obligations under the debentures or the guarantee.

WE MAY REDEEM THE DEBENTURES BEFORE           , 2030.


     Under certain circumstances, we may redeem the debentures before their
stated maturity, including the following:


     - We may redeem the debentures, in whole or in part, at any time on or
       after           , 2005.

     - We may redeem the debentures in whole, but not in part, within 180 days
       after certain occurrences at any time during the life of the trust. These
       occurrences may include adverse tax, investment company or bank
       regulatory developments.


     You should assume that we will exercise our redemption option if we are
able to obtain capital at a lower cost than we must pay on the debentures or if
it is otherwise in our interest to redeem all or some of the debentures. If
debentures are redeemed, the trust must redeem preferred securities having an
aggregate liquidation amount equal to the aggregate principal amount of
debentures redeemed, and you may be required to reinvest your principal at a
time when you may not be able to earn a return that is as high as you were
earning on the preferred securities.


                                        8
<PAGE>   14

WE CAN DISTRIBUTE THE DEBENTURES TO YOU, WHICH MAY HAVE ADVERSE TAX CONSEQUENCES
FOR YOU AND WHICH MAY ADVERSELY AFFECT THE MARKET PRICE OF THE PREFERRED
SECURITIES.

     The trust may be dissolved at any time before maturity of the debentures on
            , 2030. As a result, and subject to the terms of the trust
agreement, the trustees may distribute the debentures to you.

     We cannot predict the market prices for the debentures that may be
distributed in exchange for preferred securities upon liquidation of the trust.
The preferred securities, or the debentures that you may receive if the trust is
liquidated, may trade at a discount to the price that you paid to purchase the
preferred securities. Because you may receive debentures, your investment
decision with regard to the preferred securities will also be an investment
decision with regard to the debentures. You should carefully review all of the
information contained in this prospectus regarding the debentures.

     Under current interpretations of United States federal income tax laws
supporting classification of the trust as a grantor trust for tax purposes, a
distribution of the debentures to you upon the dissolution of the trust would
not be a taxable event to you. Nevertheless, if the trust is classified for
United States income tax purposes as an association taxable as a corporation at
the time it is dissolved, the distribution of the debentures would be a taxable
event to you. In addition, if there is a change in law, a distribution of
debentures upon the dissolution of the trust could be a taxable event to you.

THERE IS NO CURRENT PUBLIC MARKET FOR THE PREFERRED SECURITIES AND THEIR MARKET
PRICE MAY BE SUBJECT TO SIGNIFICANT FLUCTUATIONS.

     There is currently no public market for the preferred securities. Although
we have applied to list the preferred securities on the American Stock Exchange,
there is no guarantee that an active or liquid trading market will develop for
the preferred securities or that the listing of the preferred securities will
continue on the American Stock Exchange. If an active trading market does not
develop, the market price and liquidity of the preferred securities will be
adversely affected. Even if an active public market does develop, there is no
guarantee that the market price for the preferred securities will equal or
exceed the price you pay for the preferred securities.

     Future trading prices of the preferred securities may be subject to
significant fluctuations in response to prevailing interest rates, our future
operating results and financial condition, the market for similar securities and
general economic and market conditions. The initial public offering price of the
preferred securities has been set at the liquidation amount of the preferred
securities and may be greater than the market price following the offering.

     The market price for the preferred securities, or the debentures that you
may receive in a distribution, is also likely to decline during any period that
we are deferring interest payments on the debentures.

YOU MUST RELY ON THE PROPERTY TRUSTEE TO ENFORCE YOUR RIGHTS IF THERE IS AN
EVENT OF DEFAULT UNDER THE INDENTURE.

     You may not be able to directly enforce your rights against us if an event
of default under the indenture occurs. If an event of default under the
indenture occurs and is continuing, this event will also be an event of default
under the trust agreement. In that case, you must rely on the enforcement by the
property trustee of its rights as holder of the debentures against us. The
holders of a majority in liquidation amount of the preferred securities will
have the right to direct the property trustee to enforce its rights. If the
property trustee does not enforce its rights following an event of default and a
request by the record holders to do so, any record holder may, to the extent
permitted by applicable law, take action directly against us to enforce the
property trustee's rights. If an event of default occurs under the trust
agreement that is attributable to our failure to pay interest or principal on
the debentures, or if we default under the guarantee, you may proceed directly
against us. You will not be able to exercise directly any other remedies
available to the holders of the debentures unless the property trustee fails to
do so.

                                        9
<PAGE>   15

AS A HOLDER OF PREFERRED SECURITIES YOU HAVE LIMITED VOTING RIGHTS.

     Holders of preferred securities have limited voting rights. Your voting
rights pertain primarily to amendments to the trust agreement. In general, only
we can replace or remove any of the trustees. However, if an event of default
under the trust agreement occurs and is continuing, the holders of at least a
majority in aggregate liquidation amount of the preferred securities may replace
the property trustee and the Delaware trustee.

         RISKS RELATED TO AN INVESTMENT IN MIDWEST BANC HOLDINGS, INC.

CREDIT LOSSES ARE INHERENT IN OUR BUSINESS AND OUR ALLOWANCE FOR LOAN LOSSES MAY
NOT BE ADEQUATE TO COVER ACTUAL LOAN LOSSES.

     Credit losses are inherent in the lending business and could have a
material adverse effect on our operating results and our ability to make
payments on the debentures. We make various assumptions and judgments about the
collectibility of our loan portfolio and provide an allowance for loan losses
based on a number of factors. The amount of future losses is susceptible to
changes in economic, operating and other conditions, including changes in
interest rates, beyond our control. Such losses may exceed current estimates. If
our assumptions are wrong, our allowance for loan losses may not be sufficient
to cover our losses, thereby having an adverse effect on our operating results,
and may cause us to increase the allowance in the future. Additions to our
allowance for loan losses would decrease our net income.

COMMERCIAL AND COMMERCIAL REAL ESTATE LOANS REPRESENT A SIGNIFICANT PORTION OF
OUR LOAN PORTFOLIO, AND REPAYMENT OF THESE LOANS MAY BE DEPENDENT ON FACTORS
OUTSIDE OUR CONTROL OR THE CONTROL OR OUR BORROWERS.

     As of March 31, 2000, commercial real estate loans totaled $345.4 million,
or 50.0%, of our total loan portfolio. Commercial real estate lending typically
involves higher loan principal amounts and the repayment of the loans generally
is dependent, in large part, on sufficient income and cash flow from the
properties securing the loans to cover operating expenses and debt service.
Economic events or governmental regulations outside of the control of the
borrower or lender could negatively impact the future cash flow and market
values of the affected properties.

     Commercial loans were $183.5 million, or 26.6% of our total loan portfolio,
as of March 31, 2000. Our commercial loans are primarily made based on the
identified cash flow of the borrower and, to a lesser extent, based on the
underlying collateral provided by the borrower. Most often, this collateral is
accounts receivable, inventory, and machinery. In the case of loans secured by
accounts receivable, the availability of funds for the repayment of these loans
may be substantially dependent on the ability of the borrower to collect amounts
due from its customers. Virtually all loans in this category also include the
personal guaranty of the borrower or principal owner. Credit support provided by
the borrower for most of these loans and the probability of repayment depends on
the liquidation of the pledged collateral and enforcement of a personal
guarantee, if necessary. The collateral securing these loans may depreciate over
time, may be difficult to appraise and may fluctuate in value based on the
success of the business.

WE MAY EXPERIENCE DIFFICULTIES IN MANAGING OUR GROWTH.

     We have achieved significant growth during the past five years and our
strategy contemplates further growth and expansion. Although successfully
managed in the past, our growth strategy involves a variety of risks, including
our ability to:

     - to attract the management talent needed to maintain adequate depth of
       management throughout our organization as we continue to grow in the
       future;

     - maintain adequate sources of funding at attractive pricing;

                                       10
<PAGE>   16

     - maintain adequate underwriting practices and policies, as well as
       monitoring systems, to maintain credit quality and manage a growing loan
       portfolio in the future; and

     - implement appropriate policies, procedures and operating systems
       necessary to support a larger organization while preserving our
       historically low net overhead ratios.

     Failure to address these issues successfully as we grow could adversely
affect our results of operations and financial condition.

THERE IS NO ASSURANCE THAT WE WILL CONTINUE TO EXPAND.

     In addition to developing additional business in our existing markets, we
may expand our markets by establishing new banks or additional branches. If we
expand in this manner, our banks are likely to have higher operating expenses
relative to operating income, which may limit increases in short-term
profitability and could adversely affect our ability to make payments on the
preferred securities. Our ability to achieve profitable growth by establishing
new banks or branch offices is dependent on our identifying advantageous office
locations and generating sufficient levels of deposits and loans from those
locations to become profitable within a reasonable time period, typically 12 to
18 months. Though a successful strategy in the past, we cannot assure investors
that we will be able to establish additional banks or branches on a profitable
basis in the future.

WE RELY HEAVILY ON OUR MANAGEMENT AND THE UNEXPECTED LOSS OF KEY OFFICERS MAY
ADVERSELY AFFECT OUR OPERATIONS.


     Our success has been and will continue to be greatly influenced by our
ability to retain the services of existing senior management and, as we expand,
to attract and retain qualified additional senior and middle management. We
recently announced that leadership of the company will be transferred to a new
chief executive officer in connection with the planned retirement of Robert L.
Woods, our current President and Chief Executive Officer effective July 1, 2000.
Uncertainties that may be associated with this management succession, the
unexpected loss of services of any of our key management personnel, or an
inability to recruit and retain qualified personnel in the future, could have an
adverse effect on our operations and financial results. Currently, we or the
banks are beneficiaries under $1,000,000 to $2,000,000 individual key-man life
insurance policies on four key members of management, including Brad A. Luecke,
the current President of Midwest Bank and Trust Company who has been named to
succeed Mr. Woods as President and Chief Executive Officer of Midwest Banc
Holdings.


     We also depend upon the experience of the officers of our subsidiaries, the
managers of our banking facilities and on their relationships with the
communities they serve. We may not be able to retain our current key personnel
or attract additional qualified key persons as needed.

CHANGES IN LOCAL ECONOMIC CONDITIONS COULD ADVERSELY AFFECT OUR LOAN PORTFOLIO.

     Most of our lending and deposit activities are concentrated primarily in
selected communities in greater Chicago and Western Illinois. Adverse changes in
the economy of the Chicago metropolitan area and Western Illinois would likely
reduce our growth rate and could have a negative effect on our business.
Negative effects may include the demand for new loans, the availability of new
deposits as a source of funding, the ability of customers to repay loans and the
value of the collateral pledged as security for loans.

     The majority of our agricultural loans and loans to agribusinesses are
concentrated in West Central Illinois and managed by Midwest Bank of Western
Illinois. The concentration of these loans in a specific local geographic area
could affect our ability to be repaid if adverse local weather, soil or economic
conditions interfere with present and projected farming, marketing and
harvesting operations.

                                       11
<PAGE>   17

WE HAVE NO CONTROL OVER INTEREST RATES AND OTHER CONDITIONS WHICH IMPACT OUR
RESULTS OF OPERATIONS.

     Our primary source of income is the spread between the interest rates
earned on investments and loans and the interest rates paid on deposits and
other interest-bearing liabilities. Like most banking institutions, our net
interest spread and margin will be affected by general economic conditions and
other factors, including fiscal and monetary policies of the federal government,
that influence market interest rates and our ability to respond to changes in
such rates. At any given time, our asset and liabilities mix may be affected
differently by a given change in interest rates. As a result, an increase or
decrease in rates, combined with the length of loan maturities or the mix of
adjustable and fixed rate loans in our portfolio, could have a positive or
negative effect on our net income, capital and liquidity.

THERE IS STRONG COMPETITION IN THE FINANCIAL SERVICES INDUSTRY; WE MAY BE AT A
COMPETITIVE DISADVANTAGE BECAUSE SOME COMPETITORS HAVE GREATER CAPITAL RESOURCES
THAN WE DO AND MAY BE SUBJECT TO LESS REGULATION THAN WE ARE.

     We compete for loan and deposit customers with other banks and thrifts, as
well as other financial services organizations such as credit unions, finance
companies, brokerage firms, insurance companies and money market mutual funds,
all of whom aggressively solicit customers within our market areas by
advertising through direct mail, electronic media, including the Internet, and
other means. Many of the competitors in our markets have been in business for
many years, have established customer bases and are substantially larger than
us. In addition, many of these entities have greater capital resources than we
do, and some of these are not subject to the same degree of regulation. As a
result, such nonbank competitors have advantages over us in providing certain
services.

WE HAVE A CONTINUING NEED FOR TECHNOLOGICAL CHANGE, BUT MAY HAVE FEWER RESOURCES
THAN OUR COMPETITORS TO CONTINUE TO INVEST IN TECHNOLOGICAL IMPROVEMENTS.

     The financial services industry is undergoing rapid technological changes
with frequent introductions of new technology-driven products and services. In
addition to better serving customers, the effective use of technology increases
efficiency and enables financial institutions to reduce costs. Our future
success and ability to implement our growth strategy will depend in part upon
our ability to address the needs of our customers by using technology to provide
products and services that will satisfy customer demands for convenience as well
as to create additional efficiencies in our operations. Many of our competitors
have substantially greater resources to invest in technological improvements. We
cannot provide you with assurance that we will be able to effectively implement
new technology-driven products and services or be successful in marketing such
products and services to our customers.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus and information incorporated by reference in this
prospectus contains forward-looking statements which describe our future plans,
strategies and expectations. Our ability to predict results or the actual effect
of future plans or strategies is inherently uncertain. Forward-looking
statements are based on assumptions, many of which are beyond our control, and
involve risks which may cause our actual results, performance or achievements to
differ materially from the results, performance or achievements that we
anticipate. These forward-looking statements are intended to be covered by the
safe-harbor provisions of the Private Securities Litigation Reform Act of 1995.
Factors that might affect forward-looking statements include, among other
things:

     - a deterioration in the economy or business conditions, either nationally
       or in our market areas that could increase credit-related losses and
       expenses;

     - increases in defaults by borrowers and other loan delinquencies resulting
       in increases in our provision for loan losses and related expenses;

     - fluctuations in interest rates and loan and deposit pricing, which could
       reduce our net interest margins, asset valuations and expense
       expectations;
                                       12
<PAGE>   18

     - uncertainties that may be associated with the recently announced
       management succession effective upon the retirement of our current
       president and chief executive officer;

     - higher than anticipated costs related to our new banking centers or
       slower than anticipated earning asset growth which could extend
       anticipated breakeven periods at these locations;

     - failure to enter new markets successfully, an inability to capitalize on
       growth opportunities or difficulties in managing our growth, including
       possible limitations on our management depth;

     - unanticipated difficulties, costs or delays related to our pending
       acquisition of an investment services business;

     - the timing, impact and other uncertainties of possible future expansion
       opportunities and our success or failure in the integration of acquired
       operations, if any;

     - significant increases in competition, including nonbank competitors that
       are not subject to the same degree of regulation;

     - legislative or regulatory changes applicable to bank holding companies or
       our banking or other subsidiaries; and

     - changes in tax rates, tax laws or tax law interpretations.

     We undertake no obligation to publicly update or otherwise revise any
forward-looking statements, whether as a result of new information, future
events or otherwise. In light of these risks, uncertainties and assumptions, the
events discussed in any forward-looking statements in this prospectus might not
occur.

                                USE OF PROCEEDS

     The trust will invest all of the proceeds from the sale of the preferred
securities in the debentures. We anticipate that the net proceeds from the sale
of the debentures will be $23.9 million after deducting underwriting commissions
and offering expenses estimated to be $200,000.

     We expect to use approximately $12.3 million of the net proceeds to repay
all of the indebtedness currently outstanding under our revolving credit line
with a commercial bank. The credit facility provides for maximum borrowings of
$25.0 million and matures on January 31, 2002. Interest is payable on
outstanding principal balances, at the option of the company, at either the 30-,
60-, 90-, or 180-day LIBOR plus 95 basis points or the prime rate less 25 basis
points. The borrowings outstanding under the line of credit as of May 9, 2000,
mature on various dates in June and July, 2000 and bear interest at an average
annual rate of 7.03%. After this credit facility is repaid, we plan to keep the
credit line available for future borrowings.


     We also anticipate that, upon the completion of this offering, we will
contribute approximately $10.0 million of the net proceeds from the sale of the
debentures to the capital of our banking subsidiaries to support their internal
growth. We will use the remaining net proceeds for general corporate purposes,
including, but not limited to, additional capital contributions to our banks to
support future growth and to finance potential future expansion. Until these
remaining proceeds are allocated to specific uses, the funds may be used to
purchase marketable securities.

                                 CAPITALIZATION

     The following table sets forth our total deposits, indebtedness and
capitalization at March 31, 2000, on a historical basis and as adjusted for the
offering and the application of the estimated net proceeds from the
corresponding sale of the debentures as if such sale had been consummated on
March 31, 2000. This data should be read in conjunction with the consolidated
financial statements and notes thereto incorporated by reference into this
prospectus from our Annual Report on Form 10-K for the fiscal year ended
December 31, 1999 and from our Quarterly Report on Form 10-Q for the quarter

- -------------------------
(1) The notes payable under the revolving credit facility will be repaid in
    their entirety with proceeds from the sale of the debentures to the trust.

(2) The capital ratios, as adjusted, are computed including the estimated net
    proceeds from the sale of the preferred securities, in a manner consistent
    with Federal Reserve regulations.

(3) The leverage ratio is core capital divided by average quarterly assets,
    after deducting intangible assets and net deferred tax assets in excess of
    regulatory maximum limits.


(4) The preferred securities have been structured to qualify as Tier 1 capital.
    However, in calculating the amount of Tier 1 qualifying capital, the
    preferred securities, together with any outstanding cumulative preferred
    stock of Midwest Banc Holdings that may be outstanding in the future, can
    only be included up to the amount constituting 25% of total Tier 1 capital.
    As adjusted for this offering, Midwest Banc Holding's Tier 1 capital as of
    March 31, 2000, would have been approximately $100.2 million, of which $25.0
    million would have been attributable to the preferred securities.

                      ACCOUNTING AND REGULATORY TREATMENT

     The trust will be treated, for financial reporting purposes, as our
subsidiary and, accordingly, the accounts of the trust will be included in our
consolidated financial statements. The preferred securities will be presented as
a separate line item in our consolidated balance sheet under the caption
"Guaranteed preferred beneficial interests in the company's junior subordinated
debt," or other similar caption. In addition, appropriate disclosures about the
preferred securities, the guarantee and the debentures will be included in the
notes to our consolidated financial statements. For financial reporting
purposes, we will record distributions payable on the preferred securities in
our consolidated statements of income.

     Our future reports filed under the Securities Exchange Act of 1934 will
include a footnote to the consolidated financial statements stating that:

     - the trust is wholly-owned;

     - the sole assets of the trust are the debentures, specifying the
       debentures' outstanding principal amount, interest rate and maturity
       date; and

     - our obligations described in this prospectus, in the aggregate,
       constitute a full, irrevocable and unconditional guarantee on a
       subordinated basis by us of the obligations of the trust under the
       preferred securities.

     We have not included separate financial statements of the trust in this
prospectus. We do not consider that separate financial statements would be
material to holders of preferred securities because we will own all of the
trust's voting securities, the trust has no independent operations and we
guarantee the payments on the preferred securities to the extent described in
this prospectus.

                            DESCRIPTION OF THE TRUST

     The trust is a statutory business trust formed pursuant to the Delaware
Business Trust Act under a trust agreement executed by us, as sponsor for the
trust, and the trustees, and a certificate of trust filed with the Delaware
Secretary of State. The trust agreement will be amended and restated in its
entirety in the form filed as an exhibit to the registration statement of which
the prospectus is a part, as of the date the preferred securities are initially
issued. The trust agreement will be qualified under the Trust Indenture Act of
1939.

     The holders of the preferred securities issued pursuant to the offering
described in this prospectus will own all of the issued and outstanding
preferred securities of the trust which have certain prior rights over the other
securities of the trust. We will not initially own any of the preferred
securities. We will acquire common securities in an amount equal to at least 3%
of the total capital of the trust and will initially own, directly or
indirectly, all of the issued and outstanding common securities. The common
securities, together with the preferred securities, are called the trust
securities. The trust exists exclusively for the purposes of:

     - issuing the preferred securities to the public for cash;

     - issuing its common securities to us in exchange for our capitalization of
       the trust;

     - investing the proceeds from the sale of the trust securities in an
       equivalent amount of debentures; and

     - engaging in other activities that are incidental to those listed above.

     The rights of the holders of the trust securities are as set forth in the
trust agreement, the Delaware Business Trust Act and the Trust Indenture Act.
The trust agreement does not permit the trust to borrow money or make any
investment other than in the debentures. Other than with respect to the trust
securities, Midwest Banc Holdings has agreed to pay for all debts and
obligations and all costs and expenses of the trust, including the fees and
expenses of the trustees and any income taxes, duties and other governmental
charges, and all costs and expenses related to these charges, to which the trust
may become subject, except for United States withholding taxes that are properly
withheld.


     The number of trustees of the trust will initially be five. Three of the
trustees will be persons who are employees or officers of or who are affiliated
with Midwest Banc Holdings. They are the administrative trustees. The fourth
trustee will be an entity that maintains its principal place of business in the
State of Delaware. It is the Delaware trustee. Initially, Wilmington Trust
Company, a Delaware banking corporation, will act as Delaware trustee. The fifth
trustee will also initially be Wilmington Trust Company, which will serve as
institutional trustee under the trust agreement and as indenture trustee for the
purposes of compliance with the provisions of the Trust Indenture Act. It is the
property trustee. Also for purposes of compliance with the Trust Indenture Act,
Wilmington Trust Company will act as guarantee trustee and indenture trustee
under the guarantee agreement and the indenture. See "Description of the
Debentures" and "Description of the Guarantee." We, as holder of all of the
common securities, will have the right to appoint or remove any trustee unless
an event of default under the indenture has occurred and is continuing, in which
case only the holders of the preferred securities may remove the Delaware
trustee or the property trustee. The trust has a term of approximately 31 years
but may terminate earlier as provided in the trust agreement.


     The property trustee will hold the debentures for the benefit of the
holders of the trust securities and will have the power to exercise all rights,
powers and privileges under the indenture as the holder of the debentures. In
addition, the property trustee will maintain exclusive control of a segregated
noninterest-bearing "payment account" established with Wilmington Trust Company
to hold all payments made on the debentures for the benefit of the holders of
the trust securities. The property trustee will make payments of distributions
and payments on liquidation, redemption and otherwise to the holders of the
trust securities out of funds from the payment account. The guarantee trustee
will hold the guarantee for the benefit of the holders of the preferred
securities. We will pay all fees and expenses related to the trust and the
offering of the preferred securities, including the fees and expenses of the
trustees.

<PAGE>   23

                    DESCRIPTION OF THE PREFERRED SECURITIES


     The preferred securities will be issued pursuant to the trust agreement,
which will be amended and restated in connection with this offering, and which
will be qualified as an indenture under the Trust Indenture Act. Wilmington
Trust Company will act as property trustee for the preferred securities under
the trust agreement for purposes of complying with the provisions of the Trust
Indenture Act. The terms of the preferred securities will include those stated
in the trust agreement and those made part of the trust agreement by the Trust
Indenture Act. A form of the trust agreement, as to be amended and restated, has
been filed as an exhibit to the registration statement of which this prospectus
forms a part.


GENERAL

     The trust agreement authorizes the administrative trustees, on behalf of
the trust, to issue the trust securities, which are comprised of the preferred
securities to be sold to the public and the common securities. We will own all
of the common securities issued by the trust. The preferred securities will
represent preferred undivided beneficial interests in the assets of the trust,
and the holders of the preferred securities will be entitled to a preference
over the common securities upon an event of default with respect to
distributions and amounts payable on redemption or liquidation. The trust is not
permitted to issue any securities other than the trust securities or incur any
other indebtedness.

     The preferred securities will rank equally, and payments on the preferred
securities will be made proportionally, with the common securities, except as
described under " -- Subordination of Common Securities of the Trust" below.

     The property trustee will hold legal title to the debentures in trust for
the benefit of the holders of the trust securities. We will guarantee the
payment of distributions out of money held by the trust, and payments upon
redemption of the preferred securities or liquidation of the trust, to the
extent described under "Description of the Guarantee." The guarantee agreement
does not cover the payment of any distribution or the liquidation amount when
the trust does not have sufficient funds available to make these payments.

DISTRIBUTIONS

     Source of Distributions. The funds of the trust available for distribution
to holders of the preferred securities will be limited to payments made under
the debentures, which the trust will purchase with the proceeds from the sale of
the trust securities. Distributions will be paid through the property trustee,
which will hold the amounts received from our interest payments on the
debentures in the payment account for the benefit of the holders of the trust
securities. If we do not make interest payments on the debentures, the property
trustee will not have funds available to pay distributions on the preferred
securities.

     Payment of Distributions. Distributions on the preferred securities will be
payable at the annual rate of      % of the $25 stated liquidation amount,
payable quarterly on March 31, June 30, September 30 and December 31 of each
year, to the holders of the preferred securities on the relevant record dates.
So long as the preferred securities are represented by a global security, as
described below, the record date will be the business day immediately preceding
the relevant distribution date. The first distribution date for the preferred
securities will be September 30, 2000.

     Distributions will accumulate from the date of issuance, will be cumulative
and will be computed on the basis of a 360-day year of twelve 30-day months. If
the distribution date is not a business day, then payment of the distributions
will be made on the next day that is a business day, without any additional
interest or other payment for the delay. However, if the next business day is in
the next calendar year, payment of the distribution will be made on the business
day immediately preceding the scheduled distribution date. "Business day" means
any day other than a Saturday, a Sunday, a day on which banking institutions in
New York, New York are authorized or required by law, regulation or executive
order to remain closed or a day on which the corporate trust office of the
property trustee or the indenture trustee is closed for business.

                                       18
<PAGE>   24

     Extension Period. As long as no event of default under the indenture has
occurred and is continuing, we have the right to defer the payment of interest
on the debentures at any time for a period not exceeding 20 consecutive
quarters. However, no extension period may extend beyond             , 2030 or
end on a date other than an interest payment date, which dates are the same as
the distribution dates. If we defer the payment of interest, quarterly
distributions on the preferred securities will also be deferred during any such
extension period. Any deferred distributions under the preferred securities will
accumulate additional amounts at the annual rate of      %, compounded quarterly
from the relevant distribution date. The term "distributions" as used in this
prospectus includes those accumulated amounts.

     During an extension period, we may not:

     - declare or pay any dividends or distributions on, or redeem, purchase,
       acquire or make a liquidation payment with respect to, any of our capital
       stock (other than the reclassification of any class of our capital stock
       into another class of capital stock) or allow any of our subsidiaries to
       do the same with respect to their capital stock (other than the payment
       of dividends or distributions to us);

     - make any payment of principal, interest or premium on or repay,
       repurchase or redeem any debt securities that rank equally with or junior
       in interest to the debentures or allow any of our subsidiaries to do the
       same;

     - make any guarantee payments with respect to any other guarantee by us of
       any other debt securities of any of our subsidiaries if the guarantee
       ranks equally with or junior to the debentures (other than payments under
       the guarantee); or

     - redeem, purchase or acquire less than all of the debentures or any of the
       preferred securities.

After the termination of any extension period and the payment of all amounts
due, we may elect to begin a new extension period, subject to the above
requirements.


     We do not currently intend to exercise our right to defer distributions on
the preferred securities by deferring the payment of interest on the debentures.


REDEMPTION OR EXCHANGE

     General. Subject to the prior approval of the Federal Reserve, if required,
we will have the right to redeem the debentures:

     - in whole at any time, or in part from time to time, on or after
                   , 2005; or

     - at any time, in whole, within 180 days following the occurrence of a Tax
       Event, an Investment Company Event or a Capital Treatment Event, as
       defined below; or

     - at any time, to the extent of any preferred securities we repurchase plus
       a proportionate amount of the common securities we hold.

     Mandatory Redemption. Upon our repayment or redemption, in whole or in
part, of any debentures, whether on             , 2030 or earlier, the property
trustee will apply the proceeds to redeem the same amount of the trust
securities, upon not less than 30 days' nor more than 60 days' notice, at the
redemption price. The redemption price will equal 100% of the aggregate
liquidation amount of the trust securities plus accumulated but unpaid
distributions to the date of redemption. If less than all of the debentures are
to be repaid or redeemed on a date of redemption, then the proceeds from such
repayment or redemption will be allocated to redemption of preferred securities
and common securities proportionately.

     Distribution of Debentures in Exchange for Preferred Securities. Upon prior
approval of the Federal Reserve, if required, we will have the right at any time
to dissolve, wind-up or terminate the trust and, after satisfaction of the
liabilities of creditors of the trust as provided by applicable law, including,
without limitation, amounts due and owing the trustees of the trust, cause the
debentures to be distributed directly

                                       19
<PAGE>   25

to the holders of trust securities in liquidation of the trust. See
"-- Liquidation Distribution Upon Termination."

     After the liquidation date fixed for any distribution of debentures in
exchange for preferred securities:

     - those trust securities will no longer be deemed to be outstanding;

     - certificates representing debentures in a principal amount equal to the
       liquidation amount of those preferred securities will be issued in
       exchange for the preferred securities certificates;

     - we will use our reasonable efforts to list the debentures on the American
       Stock Exchange or other exchange as the preferred securities are then
       listed or traded;

     - any certificates representing trust securities that are not surrendered
       for exchange will be deemed to represent debentures with a principal
       amount equal to the liquidation amount of those preferred securities,
       accruing interest at the rate provided for in the debentures from the
       last distribution date on the preferred securities.

     - all rights of the trust securityholders other than the right to receive
       debentures upon surrender of a certificate representing trust securities
       will terminate.

     There can be no assurance as to the market prices for the preferred
securities or the debentures that may be distributed if a dissolution and
liquidation of the trust were to occur. The preferred securities that an
investor may purchase, or the 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 preferred securities.

     Redemption upon a Tax Event, Investment Company Event or Capital Treatment
Event. If a Tax Event, an Investment Company Event or a Capital Treatment Event
occurs, we will have the right to redeem the debentures in whole, but not in
part, and thereby cause a mandatory redemption of the trust securities in whole
at the redemption price. If one of these events occurs and we do not elect to
redeem the debentures, or to dissolve the trust and cause the debentures to be
distributed to holders of the trust securities, then the preferred securities
will remain outstanding and additional interest may be payable on the
debentures. See "Description of the Debentures -- Redemption or Exchange."

     "Tax Event" means the receipt by the trust and us of an opinion of counsel
experienced in such matters stating that there is more than an insubstantial
risk that:

     - interest payable by us on the debentures is not, or within 90 days of the
       date of the opinion will not be, deductible by us, in whole or in part,
       for federal income tax purposes;

     - the trust is, or will be within 90 days after the date of the opinion,
       subject to federal income tax with respect to income received or accrued
       on the debentures; or

     - the trust is, or will be within 90 days after the date of opinion,
       subject to more than an immaterial amount of other taxes, duties,
       assessments or other governmental charges, as a result of any amendment
       to any tax laws or regulations.

     "Investment Company Event" means the receipt by the trust and us of an
opinion of counsel experienced in such matters to the effect that the trust is
or will be considered an "investment company" that is required to be registered
under the Investment Company Act, as a result of a change in law or regulation
or a change in interpretation or application of law or regulation.

     "Capital Treatment Event" means the receipt by the trust and us of an
opinion of counsel experienced in such matters to the effect that there is more
than an insubstantial risk of impairment of our ability to treat the preferred
securities as Tier 1 capital for purposes of the current capital adequacy
guidelines of the Federal Reserve, as a result of any amendment to any laws or
any regulations.

     For all of the events described above, we or the trust must request and
receive an opinion with regard to the event within a reasonable period of time
after we become aware of the possible occurrence of an event of this kind.

                                       20
<PAGE>   26

     Redemption of Debentures in Exchange for Preferred Securities We
Repurchase. Upon prior approval of the Federal Reserve, if required, we will
also have the right at any time, and from time to time, to redeem debentures in
exchange for any preferred securities we may have repurchased in the market. If
we elect to surrender any preferred securities beneficially owned by us in
exchange for redemption of a like amount of debentures, we will also surrender a
proportionate amount of common securities in exchange for debentures. Preferred
securities owned by other holders will not be called for redemption at any time
when we elect to exchange trust securities we own to redeem debentures.

     The common securities we surrender will be in the same proportion to the
preferred securities we surrender as are the common securities then remaining
outstanding to the preferred securities then remaining outstanding. In exchange
for the trust securities surrendered by us, the trustee will cause to be
distributed to us debentures with a principal amount equal to the liquidation
amount of the trust securities, plus any accumulated but unpaid distributions,
if any, then held by the trustee allocable to those trust securities. After the
date of redemption involving an exchange by us, the trust securities we
surrender and the debentures distributed to us in exchange will no longer be
deemed outstanding.

REDEMPTION PROCEDURES

     Preferred securities will be redeemed at the redemption price with the
applicable proceeds from our contemporaneous redemption of the debentures.
Redemptions of the preferred securities will be made and the redemption price
will be payable on each redemption date only to the extent that the trust has
funds available for the payment of the redemption price.

     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the date of redemption to each holder of trust securities to be
redeemed at its registered address. Unless we default in payment of the
redemption price on the debentures, interest will cease to accumulate on the
debentures called for redemption on and after the date of redemption.

     If the trust gives notice of redemption of its trust securities, then the
property trustee, to the extent funds are available, will irrevocably deposit
with the depositary for the trust securities funds sufficient to pay the
aggregate redemption price and will give the depositary for the trust securities
irrevocable instructions and authority to pay the redemption price to the
holders of the trust securities. See "Book-Entry Issuance." If the preferred
securities are no longer in book-entry only form, the property trustee, to the
extent funds are available, will deposit with the designated paying agent for
such preferred securities funds sufficient to pay the aggregate redemption price
and will give the paying agent irrevocable instructions and authority to pay the
redemption price to the holders upon surrender of their certificates evidencing
the preferred securities. Notwithstanding the foregoing, distributions payable
on or prior to the date of redemption for any trust securities called for
redemption will be payable to the holders of the trust securities on the
relevant record dates for the related distribution dates.

     If notice of redemption has been given and we have deposited funds as
required, then on the date of the deposit all rights of the holders of the trust
securities called for redemption will cease, except the right to receive the
redemption price, but without interest on such redemption price after the date
of redemption. The trust securities will also cease to be outstanding on the
date of the deposit. If any date fixed for redemption of trust securities is not
a business day, then payment of the redemption price payable on that date will
be made on the next day that is a business day without any additional interest
or other payment in respect of the delay. However, if the next business day is
in the next succeeding calendar year, payment of the interest will be made on
the immediately preceding business day.

     If payment of the redemption price in respect of trust securities called
for redemption is improperly withheld or refused and not paid by the trust, or
by us pursuant to the guarantee, distributions on the trust securities will
continue to accumulate at the applicable rate from the date of redemption
originally established by the trust for the trust securities to the date the
redemption price is actually paid. In this case, the actual payment date will be
considered the date fixed for redemption for purposes of calculating the
redemption price. See "Description of the Guarantee."

                                       21
<PAGE>   27

     Payment of the redemption price on the preferred securities and any
distribution of debentures to holders of preferred securities will be made to
the applicable recordholders as they appear on the register for the preferred
securities on the relevant record date. As long as the preferred securities are
represented by a global security, the record date will be the business day
immediately preceding the date of redemption or liquidation date, as applicable.

     If less than all of the trust securities are to be redeemed, then the
aggregate liquidation amount of the trust securities to be redeemed will be
allocated proportionately to those trust securities based upon the relative
liquidation amounts. The particular preferred securities to be redeemed will be
selected by the property trustee from the outstanding preferred securities not
previously called for redemption by a method the property trustee deems fair and
appropriate. This method may provide for the redemption of portions equal to $25
or an integral multiple of $25 of the liquidation amount of the preferred
securities. The property trustee will promptly notify the registrar for the
preferred securities in writing of the preferred securities selected for
redemption and, in the case of any preferred securities selected for partial
redemption, the liquidation amount to be redeemed.

     Subject to applicable law, and if we are not exercising our right to defer
interest payments on the debentures, we may, at any time, purchase outstanding
preferred securities.

SUBORDINATION OF COMMON SECURITIES

     Payment of distributions on, and the redemption price of, the preferred
securities and common securities will be made based on the liquidation amount of
these securities. However, if an event of default under the indenture has
occurred and is continuing, no distributions on or redemption of the common
securities may be made. Furthermore, no payments may be made on the common
securities unless payment in full in cash of all accumulated and unpaid
distributions on all of the outstanding preferred securities for all
distribution periods terminating on or before that time, or in the case of
payment of the redemption price, payment of the full amount of the redemption
price on all of the outstanding preferred securities then called for redemption,
has been made or provided. All funds available to the property trustee will
first be applied to the payment in full in cash of all distributions on, or the
redemption price of, the preferred securities then due and payable.

     In the case of the occurrence and continuance of any event of default under
the trust agreement resulting from an event of default under the indenture, we,
as holder of the common securities, will be deemed to have waived any right to
act with respect to that event of default under the trust agreement until the
effect of the event of default has been cured, waived or otherwise eliminated.
Until the event of default under the trust agreement has been so cured, waived
or otherwise eliminated, the property trustee will act solely on behalf of the
holders of the preferred securities and not on our behalf, and only the holders
of the preferred securities will have the right to direct the property trustee
to act on their behalf.

LIQUIDATION DISTRIBUTION UPON TERMINATION

     We will have the right at any time to dissolve, wind-up or terminate the
trust and cause the debentures to be distributed to the holders of the preferred
securities. This right is subject, however, to us receiving approval of the
Federal Reserve, if required.

     In addition, the trust will automatically terminate upon expiration of its
term and will terminate earlier on the first to occur of:

     - our bankruptcy, dissolution or liquidation;

     - the distribution of a like amount of the debentures to the holders of
       trust securities, if we have given written direction to the property
       trustee to terminate the trust;

     - redemption of all of the preferred securities as described under
       "-- Redemption or Exchange -- Mandatory Redemption"; or

     - the entry of a court order for the dissolution of the trust.
                                       22
<PAGE>   28

     With the exception of a redemption as described under "-- Redemption or
Exchange -- Mandatory Redemption," if an early termination of the trust occurs,
the trust will be liquidated by the administrative trustees as expeditiously as
they determine to be possible. After satisfaction of liabilities to creditors of
the trust as provided by applicable law, the trustees will distribute to the
holders of trust securities debentures:

     - in an aggregate stated principal amount equal to the aggregate stated
       liquidation amount of the trust securities;

     - with an interest rate identical to the distribution rate on the trust
       securities; and

     - with accrued and unpaid interest equal to accumulated and unpaid
       distributions on the trust securities.

     However, if the property trustee determines that the distribution is not
practical, then the holders of trust securities will be entitled to receive, in
lieu of debentures, a proportionate amount of the liquidation distribution. The
liquidation distribution will be the amount equal to the aggregate of the
liquidation amount plus accumulated and unpaid distributions to the date of
payment. If the liquidation distribution can be paid only in part because the
trust has insufficient assets available to pay in full the aggregate liquidation
distribution, then the amounts payable directly by the trust on the trust
securities will be paid on a proportional basis based on liquidation amounts to
us, as the holder of the common securities, and to the holders of the preferred
securities. However, if an event of default under the indenture has occurred and
is continuing, the preferred securities will have a priority over the common
securities. See "-- Subordination of Common Securities."

     Under current United States federal income tax law and interpretations and
assuming that the trust is treated as a grantor trust, as is expected, a
distribution of the debentures should not be a taxable event to holders of the
preferred securities. Should there be a change in law, a change in legal
interpretation, a Tax Event or another circumstance, however, the distribution
could be a taxable event to holders of the preferred securities. See "Federal
Income Tax Consequences -- Receipt of Debentures or Cash Upon Liquidation of the
Trust." If we do not elect to redeem the debentures prior to maturity or to
liquidate the trust and distribute the debentures to holders of the preferred
securities, the preferred securities will remain outstanding until the repayment
of the debentures.

     If we elect to dissolve the trust and thus cause the debentures to be
distributed to holders of the preferred securities in liquidation of the trust,
we will continue to have the right to shorten the maturity of the debentures.
See "Description of the Debentures -- General."

LIQUIDATION VALUE

     The amount of the liquidation distribution payable on the preferred
securities in the event of any liquidation of the trust is $25 per preferred
security plus accumulated and unpaid distributions to the date of payment, which
may be in the form of a distribution of debentures having a liquidation value
and accrued interest of an equal amount. See "-- Liquidation Distribution Upon
Termination."

EVENTS OF DEFAULT; NOTICE

     Any one of the following events constitutes an event of default under the
trust agreement with respect to the preferred securities:

     - the occurrence of an event of default under the indenture (see
       "Description of the Debentures -- Debenture Events of Default");

     - a default by the trust in the payment of any distribution when it becomes
       due and payable, and continuation of the default for a period of 30 days;

     - a default by the trust in the payment of any redemption price of any of
       the trust securities when it becomes due and payable;

                                       23
<PAGE>   29

     - a default in the performance, or breach, in any material respect, of any
       covenant or warranty of the trustees in the trust agreement, other than
       those defaults covered in the previous two points, and continuation of
       the default or breach for a period of 60 days after there has been given,
       by registered or certified mail, to the trustee(s) by the holders of at
       least 25% in aggregate liquidation amount of the outstanding preferred
       securities, a written notice specifying the default or breach and
       requiring it to be remedied and stating that the notice is a "Notice of
       Default" under the trust agreement; or

     - the occurrence of events of bankruptcy or insolvency with respect to the
       property trustee and our failure to appoint a successor property trustee
       within 60 days.

     Within five business days after the occurrence of any event of default
actually known to the property trustee, the property trustee will transmit
notice of the event of default to the holders of the preferred securities, the
administrative trustees and to us, unless the event of default has been cured or
waived. Midwest Banc Holdings 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 trust agreement.

     If an event of default under the indenture has occurred and is continuing,
the preferred securities will have preference over the common securities upon
termination of the trust. See "-- Subordination of Common Securities" and
"-- Liquidation Distribution Upon Termination." The existence of an event of
default under the trust agreement does not entitle the holders of preferred
securities to accelerate the maturity thereof, unless the event of default is
caused by the occurrence of an event of default under the indenture and both the
indenture trustee and holders of at least 25% in principal amount of the
debentures fail to accelerate the maturity thereof.

REMOVAL OF THE TRUSTEES

     Unless an event of default under the indenture has occurred and is
continuing, we may remove any trustee at any time. If an event of default under
the indenture has occurred and is continuing, only the holders of a majority in
liquidation amount of the outstanding preferred securities may remove the
property trustee or the Delaware trustee. The holders of the preferred
securities have no right to vote to appoint, remove or replace the
administrative trustees. These rights are vested exclusively with us as the
holder of the common securities. No resignation or removal of a trustee and no
appointment of a successor trustee will be effective until the successor trustee
accepts the appointment in accordance with the trust agreement.

CO-TRUSTEES AND SEPARATE PROPERTY TRUSTEE

     Unless an event of default under the indenture has occurred and is
continuing, for the purpose of meeting the legal requirements of the Trust
Indenture Act or of any jurisdiction in which any part of the trust property may
at the time be located, we will have the power to appoint at any time or times,
and upon written request of the property trustee will appoint, one or more
persons or entity either (1) to act as a co-trustee, jointly with the property
trustee, of all or any part of the trust property, or (2) to act as separate
trustee of any trust property. In either case these trustees will have the
powers that may be provided in the instrument of appointment, and will have
vested in them any property, title, right or power deemed necessary or
desirable, subject to the provisions of the trust agreement. In case an event of
default under the indenture has occurred and is continuing, the property trustee
alone will have power to make the appointment.

MERGER OR CONSOLIDATION OF TRUSTEES

     Generally, any person or successor to any of the trustees may be a
successor trustee to any of the trustees, including a successor resulting from a
merger or consolidation. However, any successor trustee must meet all of the
qualifications and eligibility standards to act as a trustee.

                                       24
<PAGE>   30

MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE TRUST

     The trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other person, except as
described below. The trust may, at our request, with the consent of the
administrative trustees and without the consent of the holders of the preferred
securities, the property trustee or the Delaware trustee, undertake a
transaction listed above if the following conditions are met:

     - the successor entity either (a) expressly assumes all of the obligations
       of the trust with respect to the preferred securities, or (b) substitutes
       for the preferred securities other securities having substantially the
       same terms as the preferred securities (referred to as "successor
       securities") so long as the successor securities rank the same in
       priority as the preferred securities with respect to distributions and
       payments upon liquidation, redemption and otherwise;

     - we appoint a trustee of the successor entity possessing substantially the
       same powers and duties as the property trustee in its capacity as the
       holder of the debentures;

     - the successor securities are listed or traded or will be listed or traded
       on any national securities exchange or other organization on which the
       preferred securities are then listed, if any;

     - the merger, consolidation, amalgamation, replacement, conveyance,
       transfer or lease does not adversely affect the rights, preferences and
       privileges of the holders of the preferred securities (including any
       successor securities) in any material respect;

     - the successor entity has a purpose substantially identical to that of the
       trust;

     - prior to the merger, consolidation, amalgamation, replacement,
       conveyance, transfer or lease, we have received an opinion from
       independent counsel that (a) any transaction of this kind does not
       adversely affect the rights, preferences and privileges of the holders of
       the preferred securities (including any successor securities) in any
       material respect, and (b) following the transaction, neither the trust
       nor the successor entity will be required to register as an "investment
       company" under the Investment Company Act; and

     - we own all of the common securities of the successor entity and guarantee
       the obligations of the successor entity under the successor securities at
       least to the extent provided by the guarantee.

Notwithstanding the foregoing, the trust may not, except with the consent of
every holder of the preferred securities, enter into any transaction of this
kind if the transaction 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 TRUST AGREEMENT

     Except as described below and under "Description of the
Guarantee -- Amendments and Assignment" and as otherwise required by the Trust
Indenture Act and the trust agreement, the holders of the preferred securities
will have no voting rights.

     The trust agreement may be amended from time to time by us and the
trustees, without the consent of the holders of the preferred securities, in the
following circumstances:

     - with respect to acceptance of appointment by a successor trustee;

     - to cure any ambiguity, correct or supplement any provisions in the trust
       agreement that may be inconsistent with any other provision, or to make
       any other provisions with respect to matters or questions arising under
       the trust agreement, as long as the amendment is not inconsistent with
       the other provisions of the trust agreement and does not have a material
       adverse effect on the interests of any holder of trust securities; or

     - to modify, eliminate or add to any provisions of the trust agreement if
       necessary to ensure that the trust will be classified for federal income
       tax purposes as a grantor trust at all times that any trust

                                       25
<PAGE>   31

       securities are outstanding or to ensure that the trust will not be
       required to register as an "investment company" under the Investment
       Company Act.

     With the consent of the holders of a majority of the aggregate liquidation
amount of the outstanding trust securities, we and the trustees may amend the
trust agreement if the trustees receive an opinion of counsel to the effect that
the amendment or the exercise of any power granted to the trustees in accordance
with the amendment will not affect the trust's status as a grantor trust for
federal income tax purposes or the trust's exemption from status as an
"investment company" under the Investment Company Act. However, without the
consent of each holder of trust securities, the trust agreement may not be
amended to (a) 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 (b)
restrict the right of a holder of trust securities to institute suit for the
enforcement of the payment on or after that date.

     As long as the property trustee holds any debentures, the trustees will
not:

     - direct the time, method and place of conducting any proceeding for any
       remedy available to the indenture trustee, or executing any trust or
       power conferred on the property trustee with respect to the debentures;

     - waive any past default that is waivable under the indenture;

     - exercise any right to rescind or annul a declaration that the principal
       of all the debentures will be due and payable; or

     - consent to any amendment or termination of the indenture or the
       debentures, where the consent is required, without obtaining the prior
       approval of the holders of a majority in aggregate liquidation amount of
       all outstanding preferred securities. However, where a consent under the
       indenture requires the consent of each holder of the affected debentures,
       no consent will be given by the property trustee without the prior
       consent of each holder of the preferred securities.

The trustees may not revoke any action previously authorized or approved by a
vote of the holders of the preferred securities except by subsequent vote of the
holders of the preferred securities. The property trustee will notify each
holder of preferred securities of any notice of default with respect to the
debentures. In addition to obtaining the foregoing approvals of the holders of
the preferred securities, prior to taking any of the foregoing actions, the
trustees must obtain an opinion of counsel experienced in these matters to the
effect that the trust will not be classified as an association taxable as a
corporation for federal income tax purposes on account of the action.

     Any required approval of holders of trust securities may be given at a
meeting of holders of the trust securities convened for the purpose or pursuant
to written consent. The property trustee will cause a notice of any meeting at
which holders of the trust securities are entitled to vote, or of any matter
upon which action by written consent of the holders is to be taken, to be given
to each holder of record of trust securities.

     No vote or consent of the holders of preferred securities will be required
for the trust to redeem and cancel its preferred securities in accordance with
the trust agreement.

     Notwithstanding the fact that holders of preferred securities are entitled
to vote or consent under any of the circumstances described above, any of the
preferred securities that are owned by Midwest Banc Holdings, the trustees or
any affiliate of Midwest Banc Holdings or any trustee, will, for purposes of the
vote or consent, be treated as if they were not outstanding.

GLOBAL PREFERRED SECURITIES

     The preferred securities will be represented by one or more global
preferred securities registered in the name of The Depository Trust Company, New
York, New York ("DTC"), or its nominee. A global preferred security is a
security representing interests of more than one beneficial holder. Ownership of

                                       26
<PAGE>   32

beneficial interests in the global preferred securities will be reflected in DTC
participant account records through DTC's book-entry transfer and registration
system. Participants are brokers, dealers, or others having accounts with DTC.
Indirect beneficial interests of other persons investing in the preferred
securities will be shown on, and transfers will be effected only through,
records maintained by DTC participants. Except as described below, preferred
securities in definitive form will not be issued in exchange for the global
preferred securities. See "Book-Entry Issuance."

     No global preferred security may be exchanged for preferred securities
registered in the names of persons other than DTC or its nominee unless:

     - DTC notifies the indenture trustee that it is unwilling or unable to
       continue as a depositary for the global preferred security and we are
       unable to locate a qualified successor depositary;

     - we execute and deliver to the indenture trustee a written order stating
       that we elect to terminate the book-entry system through DTC; or

     - there shall have occurred and be continuing an event of default under the
       indenture.

Any global preferred security that is exchangeable pursuant to the preceding
sentence shall be exchangeable for definitive certificates registered in the
names as DTC shall direct. It is expected that the instructions will be based
upon directions received by DTC with respect to ownership of beneficial
interests in the global preferred security. If preferred securities are issued
in definitive form, the preferred securities will be in denominations of $25 and
integral multiples of $25 and may be transferred or exchanged at the offices
described below.

     Unless and until it is exchanged in whole or in part for the individual
preferred securities represented thereby, a global preferred security may not be
transferred except as a whole by DTC to a nominee of DTC, by a nominee of DTC to
DTC or another nominee of DTC or by DTC or any nominee to a successor depositary
or any nominee of the successor.

     Payments on global preferred securities will be made to DTC, as the
depositary for the global preferred securities. If the preferred securities are
issued in definitive form, distributions will be payable by check mailed to the
address of record of the persons entitled to the distribution, and the transfer
of the preferred securities will be registrable, and preferred securities will
be exchangeable for preferred securities of other denominations of a like
aggregate liquidation amount, at the corporate office of the property trustee,
or at the offices of any paying agent or transfer agent appointed by the
administrative trustees. In addition, if the preferred securities are issued in
definitive form, the record dates for payment of distributions will be the 15th
day of the month in which the relevant distribution date occurs. For a
description of the terms of DTC arrangements relating to payments, transfers,
voting rights, redemptions and other notices and other matters, see "Book-Entry
Issuance."

     Upon the issuance of one or more global preferred securities, and the
deposit of the global preferred security with or on behalf of DTC or its
nominee, DTC or its nominee will credit, on its book-entry registration and
transfer system, the respective aggregate liquidation amounts of the individual
preferred securities represented by the global preferred security to the
designated accounts of persons that participate in the DTC system. These
participant accounts will be designated by the dealers, underwriters or agents
selling the preferred securities. Ownership of beneficial interests in a global
preferred security will be limited to persons or entities having an account with
DTC or who may hold interests through participants. With respect to interests of
any person or entity that is a DTC participant, ownership of beneficial
interests in a global preferred security will be shown on, and the transfer of
that ownership will be effected only through, records maintained by DTC or its
nominee. With respect to persons or entities who hold interests in a global
preferred security through a participant, the interest and any transfer of the
interest will be shown only on the participant's records. The laws of some
states require that certain purchasers of securities take physical delivery of
securities in definitive form. These laws may impair the ability to transfer
beneficial interests in a global preferred security.

                                       27
<PAGE>   33

     So long as DTC or another depositary, or its nominee, is the registered
owner of the global preferred security, the depositary or the nominee, as the
case may be, will be considered the sole owner or holder of the preferred
securities represented by the global preferred security for all purposes under
the trust agreement. Except as described in this prospectus, owners of
beneficial interests in a global preferred security will not be entitled to have
any of the individual preferred securities represented by the global preferred
security registered in their names, will not receive or be entitled to receive
physical delivery of any the preferred securities in definitive form and will
not be considered the owners or holders of the preferred securities under the
trust agreement.

     None of us, the property trustee, any paying agent or the securities
registrar for the preferred securities will have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of the global preferred security representing the
preferred securities or for maintaining, supervising or reviewing any records
relating to the beneficial ownership interests.

     We expect that DTC or its nominee, upon receipt of any payment of the
liquidation amount or distributions in respect of a global preferred security,
immediately will credit participants' accounts with payments in amounts
proportionate to their respective beneficial interest in the aggregate
liquidation amount of the global preferred security as shown on the records of
DTC or its nominee. We also expect that payments by participants to owners of
beneficial interests in the global preferred security held through the
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers in bearer
form or registered in "street name." The payments will be the responsibility of
the participants. See "Book-Entry Issuance."

PAYMENT AND PAYING AGENCY

     Payments in respect of the preferred securities shall be made to DTC, which
shall credit the relevant accounts of participants on the applicable
distribution dates, or, if any of the preferred securities are not held by DTC,
the payments shall be made by check mailed to the address of the holder as
listed on the register of holders of the preferred securities. The paying agent
for the preferred securities will initially be the property trustee and any
co-paying agent chosen by the property trustee and acceptable to us and the
administrative trustees. The paying agent for the preferred securities may
resign as paying agent upon 30 days' written notice to the administrative
trustees, the property trustee and us. If the property trustee no longer is the
paying agent for the preferred securities, the administrative trustees will
appoint a successor to act as paying agent. The successor must be a bank or
trust company acceptable to us and the property trustee.

REGISTRAR AND TRANSFER AGENT

     The property trustee will act as the registrar and the transfer agent for
the preferred securities. Registration of transfers of preferred 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 and its registrar and transfer agent will not be
required to register or cause to be registered the transfer of preferred
securities after they have been called for redemption.

INFORMATION CONCERNING THE PROPERTY TRUSTEE


     The property trustee, until the occurrence and continuance of an event of
default under the trust agreement, undertakes to perform only the duties set
forth in the trust agreement. After an event of default under the trust
agreement, the property trustee must exercise the same degree of care and skill
as a prudent person exercises or uses in the conduct of its own affairs. The
property trustee is under no obligation to exercise any of the powers vested in
it by the trust agreement at the request of any holder of preferred securities
unless it is offered reasonable indemnity against the costs, expenses and
liabilities that might be incurred. If no event of default under the trust
agreement has occurred and is continuing and the property trustee is required to
decide between alternative causes of action, construe ambiguous or


                                       28
<PAGE>   34

inconsistent provisions in the trust agreement or is unsure of the application
of any provision of the trust agreement, and the matter is not one on which
holders of preferred securities are entitled to vote upon, then the property
trustee will take the action directed in writing by us. If the property trustee
is not so directed, then it will take the action it deems advisable and in the
best interests of the holders of the trust securities and will have no liability
except for its own bad faith, negligence or willful misconduct.

MISCELLANEOUS

     The administrative trustees are authorized and directed to conduct the
affairs of and to operate the trust in such a way that:

     - the trust will not be deemed to be an "investment company" required to be
       registered under Investment Company Act;

     - the trust will not be classified as an association taxable as a
       corporation for federal income tax purposes; and

     - the debentures will be treated as indebtedness of Midwest Banc Holdings
       for federal income tax purposes.

In this regard, we and the administrative trustees are authorized to take any
action not inconsistent with applicable law, the certificate of trust or the
trust agreement, that we and the administrative trustees determine to be
necessary or desirable for these purposes.

     Holders of the preferred securities have no preemptive or similar rights.
The trust agreement and the trust securities will be governed by Delaware law.

                         DESCRIPTION OF THE DEBENTURES

     Concurrently with the issuance of the preferred securities, the trust will
invest the proceeds from the sale of the trust securities in the debentures
issued by us. The debentures will be issued as unsecured debt under the
indenture between us and Wilmington Trust Company, as indenture trustee. The
indenture will be qualified under the Trust Indenture Act.

     The following discussion is subject to, and is qualified in its entirety by
reference to, the indenture and to the Trust Indenture Act. We urge prospective
investors to read the form of the indenture, which is filed as an exhibit to the
registration statement of which this prospectus forms a part.

GENERAL

     The debentures will be limited in aggregate principal amount to
$25,773,200. This amount represents the sum of the aggregate stated liquidation
amounts of the trust securities. The debentures will bear interest at the annual
rate of   % of the principal amount. The interest will be payable quarterly on
March 31, June 30, September 30 and December 31 of each year, beginning
September 30, 2000, to the person in whose name each debenture is registered at
the close of business on the 15th day of the last month of the calendar quarter.
It is anticipated that, until the liquidation, if any, of the trust, the
debentures 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. If any date on which interest is
payable on the debentures is not a business day, then payment of interest will
be made on the next day that is a business day without any additional interest
or other payment in respect of the delay. However, if the next business day is
in the next calendar year, payment of interest will be made on the immediately
preceding business day. Accrued interest that is not paid on the applicable
interest payment date will bear additional interest on the amount due at the
annual rate of   %, compounded quarterly.


                                       29
<PAGE>   35

     The debentures will mature on             , 2030, the stated maturity date.
We may shorten this date once at any time to any date not earlier than
            , 2005, subject to the prior approval of the Federal Reserve, if
required.

     We will give notice to the indenture trustee and the holders of the
debentures, no more than 180 days and no less than 90 days prior to the
effectiveness of any change in the stated maturity date. We will not have the
right to redeem the debentures from the trust until after             , 2005,
except if (a) a Tax Event, an Investment Company Event or a Capital Treatment
Event has occurred, or (b) we repurchase preferred securities in the market, in
which case we can elect to redeem debentures specifically in exchange for a like
amount of preferred securities owned by us plus a proportionate amount of common
securities.

     The debentures will be unsecured and will rank junior to all of our senior
and subordinated debt, including indebtedness we may incur in the future.
Because we are a holding company, our right to participate in any distribution
of assets of any of our subsidiaries, upon any subsidiary's liquidation or
reorganization or otherwise, and thus the ability of holders of the debentures
to benefit indirectly from any distribution by a subsidiary, is subject to the
prior claim of creditors of the subsidiary, except to the extent that we may be
recognized as a creditor of the subsidiary. The debentures will, therefore, be
effectively subordinated to all existing and future liabilities of our
subsidiaries, and holders of debentures should look only to our assets for
payment. The indenture does not limit our ability to incur or issue secured or
unsecured senior and junior debt. See "-- Subordination."

     The indenture does not contain provisions that afford holders of the
debentures protection in the event of a highly leveraged transaction or other
similar transaction involving us, nor does it require us to maintain or achieve
any financial performance levels or to obtain or maintain any credit rating on
the debentures.

OPTION TO EXTEND INTEREST PAYMENT PERIOD

     As long as no event of default under the indenture has occurred and is
continuing, we have the right under the indenture to defer the payment of
interest on the debentures at any time for a period not exceeding 20 consecutive
quarters. However, no extension period may extend beyond the stated maturity of
the debentures or end on a date other than a date interest is normally due. At
the end of an extension period, we must pay all interest then accrued and
unpaid, together with interest thereon at the annual rate of      %, compounded
quarterly. During an extension period, interest will continue to accrue and
holders of debentures, or the holders of preferred securities if they are then
outstanding, will be required to accrue and recognize as income for federal
income tax purposes the accrued but unpaid interest amounts in the year in which
such amounts accrued. See "Federal Income Tax Consequences -- Interest Payment
Period and Original Issue Discount."

     During an extension period, we may not:

     - declare or pay any dividends or distributions on, or redeem, purchase,
       acquire or make a liquidation payment with respect to, any of our capital
       stock (other than the reclassification of any class of capital stock into
       another class of capital stock) or allow any of our subsidiaries to do
       the same with respect to their capital stock (other than payment of
       dividends or distributions to us);

     - make or allow any of our subsidiaries to make any payment of principal,
       interest or premium on, or repay, repurchase or redeem any debt
       securities issued by us that rank equally with or junior to the
       debentures;

     - make or allow any of our subsidiaries to make any guarantee payments with
       respect to any other guarantee by us of any other debt securities of any
       of our subsidiaries if the guarantee ranks equally with or junior to the
       debentures (other than payments under the guarantee); or

     - redeem, purchase or acquire less than all of the debentures or any of the
       preferred securities.

                                       30
<PAGE>   36

     Prior to the termination of any extension period, so long as no event of
default under the indenture is continuing, we may further defer the payment of
interest subject to the above stated requirements. Upon the termination of any
extension period and the payment of all amounts then due, we may elect to begin
a new extension period at any time. We do not currently intend to exercise our
right to defer payments of interest on the debentures.

     We must give the property trustee, the administrative trustees and the
indenture trustee notice of our election of an extension period at least two
business days prior to the earlier of (a) the next date on which distributions
on the trust securities would have been payable except for the election to begin
an extension period, or (b) the date we are required to give notice of the
record date, or the date the distributions are payable, to the American Stock
Exchange, or other applicable self-regulatory organization, or to holders of the
preferred securities, but in any event at least one business day prior to the
record date.

     Other than as described above, there is no limitation on the number of
times that we may elect to begin an extension period.

ADDITIONAL SUMS TO BE PAID AS A RESULT OF ADDITIONAL TAXES

     If the trust is required to pay any additional taxes, duties, assessments
or other governmental charges as a result of the occurrence of a Tax Event, we
will pay as additional interest on the debentures any amounts which may be
required so that the net amounts received and retained by the trust after paying
any additional taxes, duties, assessments or other governmental charges will not
be less than the amounts the trust would have received had the additional taxes,
duties, assessments or other governmental charges not been imposed.

REDEMPTION

     Subject to prior approval of the Federal Reserve, if required, we may
redeem the debentures prior to maturity:

     - on or after             , 2005, in whole at any time or in part from time
       to time;

     - in whole at any time within 180 days following the occurrence of a Tax
       Event, an Investment Company Event or a Capital Treatment Event; or

     - at any time, to the extent of any preferred securities we repurchase plus
       a proportionate amount of the common securities we hold.

In each case we will pay a redemption price equal to the accrued and unpaid
interest on the debentures so redeemed to the date fixed for redemption, plus
100% of the principal amount of the redeemed debentures.

     Notice of any redemption will be mailed at least 30 days but not more than
60 days before the redemption date to each holder of debentures to be redeemed
at its registered address. Redemption of less than all outstanding debentures
must be effected proportionately, by lot or in any other manner deemed to be
fair and appropriate by the indenture trustee. Unless we default in payment of
the redemption price for the debentures, on and after the redemption date
interest will no longer accrue on the debentures or the portions of the
debentures called for redemption.

     The debentures will not be subject to any sinking fund.

DISTRIBUTION UPON LIQUIDATION

     As described under "Description of the Preferred Securities -- Liquidation
Distribution Upon Termination," under certain circumstances and with the Federal
Reserve's approval, the debentures may be distributed to the holders of the
preferred securities in liquidation of the trust after satisfaction of
liabilities to creditors of the trust. If this occurs, we will use our
reasonable efforts to list the debentures on the American Stock Exchange or
other stock exchange or national quotation system on which the

                                       31
<PAGE>   37

preferred securities are then listed, if any. There can be no assurance as to
the market price of any debentures that may be distributed to the holders of
preferred securities.

RESTRICTIONS ON PAYMENTS


     We are restricted from making certain payments (as described below) if we
have chosen to defer payment of interest on the debentures, if an event of
default has occurred and is continuing under the indenture, or if we are in
default with respect to our obligations under the guarantee.



     If any of these events occur, we will not:


     - declare or pay any dividends or distributions on, or redeem, purchase,
       acquire, or make a liquidation payment with respect to, any of our
       capital stock (other than the reclassification of any class of our
       capital stock into another class of capital stock) or allow any of our
       subsidiaries to do the same with respect to their capital stock (other
       than payment of dividends or distributions to us);

     - make or allow any of our subsidiaries to make any payment of principal,
       interest or premium on, or repay or repurchase or redeem any of our debt
       securities that rank equally with or junior to the debentures;

     - make or allow any of our subsidiaries to make any guarantee payments with
       respect to any guarantee by us of the debt securities of any of our
       subsidiaries if the guarantee ranks equally with or junior to the
       debentures (other than payments under the guarantee); or

     - redeem, purchase or acquire less than all of the debentures or any of the
       preferred securities.

SUBORDINATION

     The debentures are subordinated and junior in right of payment to all of
our senior and subordinated debt (as defined below). Upon any payment or
distribution of assets to creditors upon any liquidation, dissolution, winding
up or reorganization of Midwest Banc Holdings, whether voluntary or involuntary
in bankruptcy, insolvency, receivership or other proceedings in connection with
any insolvency or bankruptcy proceedings, the holders of our senior and
subordinated debt will first be entitled to receive payment in full of principal
and interest before the holders of debentures will be entitled to receive or
retain any payment in respect of the debentures.

     If the maturity of any debentures is accelerated, the holders of all of our
senior and subordinated debt outstanding at the time of the acceleration will
also be entitled to first receive payment in full of all amounts due to them,
including any amounts due upon acceleration, before the holders of the
debentures will be entitled to receive or retain any principal or interest
payments on the debentures.

     No payments of principal or interest on the debentures may be made if there
has occurred and is continuing a default in any payment with respect to any of
our senior or subordinated debt or an event of default with respect to any of
our senior or subordinated debt resulting in the acceleration of the maturity of
the senior or subordinated debt, or if any judicial proceeding is pending with
respect to any default.

     The term "debt" means, with respect to any person, whether recourse is to
all or a portion of the assets of the person and whether or not contingent:

     - every obligation of the person for money borrowed;

     - every obligation of the person evidenced by bonds, debentures, notes or
       other similar instruments, including obligations incurred in connection
       with the acquisition of property, assets or businesses;

     - every reimbursement obligation of the person with respect to letters of
       credit, bankers' acceptances or similar facilities issued for the account
       of the person;

     - every obligation of the person issued or assumed as the deferred purchase
       price of property or services, excluding trade accounts payable or
       accrued liabilities arising in the ordinary course of business;
                                       32
<PAGE>   38

     - every capital lease obligation of the person; and

     - every obligation of the type referred to in the first five points of
       another person and all dividends of another person the payment of which,
       in either case, the first person has guaranteed or is responsible or
       liable, directly or indirectly, as obligor or otherwise.

     The term "senior debt" means the principal of, and premium and interest,
including interest accruing on or after the filing of any petition in bankruptcy
or for reorganization relating to us, on, debt, whether incurred on or prior to
the date of the indenture or incurred after the date. However, senior debt will
not be deemed to include:

     - any debt where it is provided in the instrument creating the debt that
       the obligations are not superior in right of payment to the debentures or
       to other debt which is equal with, or subordinated to, the debentures;

     - any of our debt that when incurred and without regard to any election
       under the federal bankruptcy laws, was without recourse to us;

     - any debt of ours to any of our subsidiaries;

     - any debt to any of our employees;

     - any debt that by its terms is subordinated to trade accounts payable or
       accrued liabilities arising in the ordinary course of business to the
       extent that payments made to the holders of the debt by the holders of
       the debentures as a result of the subordination provisions of the
       indenture would be greater than they otherwise would have been as a
       result of any obligation of the holders to pay amounts over to the
       obligees on the trade accounts payable or accrued liabilities arising in
       the ordinary course of business as a result of subordination provisions
       to which the debt is subject; and

     - debt which constitutes subordinated debt.

     The term "subordinated debt" means the principal of, and premium and
interest, including interest accruing on or after the filing of any petition in
bankruptcy or for reorganization relating to us, on, debt. Subordinated debt
includes debt incurred on or prior to the date of the indenture or thereafter
incurred, which is by its terms expressly provided to be junior and subordinate
to other debt of ours, other than the debentures. However, subordinated debt
will not be deemed to include:

     - any of our debt which when incurred and without regard to any election
       under the federal bankruptcy laws was without recourse to us;

     - any debt of ours to any of our subsidiaries;

     - any debt to any of our employees;

     - any debt which by its terms is subordinated to trade accounts payable or
       accrued liabilities arising in the ordinary course of business to the
       extent that payments made to the holders of the debt by the holders of
       the debentures as a result of the subordination provisions of the
       indenture would be greater than they otherwise would have been as a
       result of any obligation of the holders to pay amounts over to the
       obligees on the trade accounts payable or accrued liabilities arising in
       the ordinary course of business as a result of subordination provisions
       to which the debt is subject;

     - debt which constitutes senior debt; and

     - any debt of ours under debt securities (and guarantees in respect of
       these debt securities) initially issued to any trust, or a trustee of a
       trust, partnership or other entity affiliated with us that is, directly
       or indirectly, our financing vehicle in connection with the issuance by
       that entity of preferred securities or other securities which are
       intended to qualify for "Tier 1" capital treatment.


     We expect from time to time to incur additional indebtedness, and there is
no limitation under the indenture on the amount we may incur. We had
consolidated senior and subordinated debt of $269.0 million at March 31, 2000.
Although a portion of these amounts is expected to be repaid with a

                                       33
<PAGE>   39


portion of the proceeds from the sale of the debentures, we expect to incur
additional senior or subordinated debt in the future.


PAYMENT AND PAYING AGENTS

     Generally, payment of principal of and interest on the debentures will be
made at the office of the indenture trustee in Wilmington, Delaware. However, we
have the option to make payment of any interest by (a) check mailed to the
address of the person entitled to payment at the address listed in the register
of holders of the debentures, or (b) wire transfer to an account maintained by
the person entitled thereto as specified in the register of holders of the
debentures, provided that proper transfer instructions have been received by the
applicable record date. Payment of any interest on debentures will be made to
the person in whose name the debenture is registered at the close of business on
the regular record date for the interest payment, except in the case of
defaulted interest.

     Any moneys deposited with the indenture trustee or any paying agent for the
debentures, or then held by us in trust, for the payment of the principal of or
interest on the debentures and remaining unclaimed for two years after the
principal or interest has become due and payable, will be repaid to us on June
30 of each year. If we hold any of this money in trust, then it will be
discharged from the trust to us and the holder of the debenture will thereafter
look, as a general unsecured creditor, only to us for payment.

REGISTRAR AND TRANSFER AGENT

     The indenture trustee will act as the registrar and the transfer agent for
the debentures. Debentures may be presented for registration of transfer, with
the form of transfer endorsed thereon, or a satisfactory written instrument of
transfer, duly executed, at the office of the registrar. Provided that we
maintain a transfer agent in Wilmington, Delaware, we may rescind the
designation of any transfer agent or approve a change in the location through
which any transfer agent acts. We may at any time designate additional transfer
agents with respect to the debentures.

     If we redeem any of the debentures, neither we nor the indenture trustee
will be required to (a) issue, register the transfer of or exchange any
debentures during a period beginning at the opening of business 15 days before
the day of the mailing of and ending at the close of business on the day of the
mailing of the relevant notice of redemption, or (b) transfer or exchange any
debentures so selected for redemption, except, in the case of any debentures
being redeemed in part, any portion not to be redeemed.

MODIFICATION OF INDENTURE

     We and the indenture trustee may, from time to time without the consent of
the holders of the debentures, amend, waive our rights under or supplement the
indenture for purposes which do not materially adversely affect the rights of
the holders of the debentures. Other changes may be made by us and the indenture
trustee with the consent of the holders of a majority in principal amount of the
outstanding debentures. However, without the consent of the holder of each
outstanding debenture affected by the proposed modification, no modification
may:

     - extend the maturity date of the debentures; or

     - reduce the principal amount or the rate or extend the time of payment of
       interest; or

     - reduce the percentage of principal amount of debentures required to amend
       the indenture.

     As long as any of the preferred securities remain outstanding, no
modification of the indenture may be made that requires the consent of the
holders of the debentures, no termination of the indenture may occur, and no
waiver of any event of default under the indenture may be effective, without the
prior consent of the holders of a majority of the aggregate liquidation amount
of the preferred securities.

                                       34
<PAGE>   40

DEBENTURE EVENTS OF DEFAULT

     The indenture provides that any one or more of the following events with
respect to the debentures that has occurred and is continuing constitutes an
event of default under the indenture:

     - our failure to pay any interest on the debentures for 30 days after the
       due date, except where we have properly deferred the interest payment;

     - our failure to pay any principal on the debentures when due whether at
       maturity, upon redemption or otherwise;

     - our failure to observe or perform in any material respect any other
       covenants or agreements contained in the indenture for 90 days after
       written notice to us from the indenture trustee or the holders of at
       least 25% in aggregate outstanding principal amount of the debentures; or

     - our bankruptcy, insolvency or reorganization or dissolution of the trust.

     The holders of a majority of the aggregate outstanding principal amount of
the debentures have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the indenture trustee. The indenture
trustee, or the holders of at least 25% in aggregate outstanding principal
amount of the debentures, may declare the principal due and payable immediately
upon an event of default under the indenture. The holders of a majority of the
outstanding principal amount of the debentures may rescind and annul the
declaration and waive the default if the default has been cured and a sum
sufficient to pay all matured installments of interest and principal due
otherwise than by acceleration, has been deposited with the indenture trustee.
The holders may not annul the declaration and waive a default if the default is
the non-payment of the principal of the debentures which has become due solely
by the acceleration. Should the holders of the debentures fail to annul the
declaration and waive the default, the holders of at least 25% in aggregate
liquidation amount of the preferred securities will have this right.

     If an event of default under the indenture has occurred and is continuing,
the property trustee will have the right to declare the principal of and the
interest on the debentures, and any other amounts payable under the indenture,
to be immediately due and payable and to enforce its other rights as a creditor
with respect to the debentures.

     We are required to file annually with the indenture trustee a certificate
as to whether or not we are in compliance with all of the conditions and
covenants applicable to us under the indenture.

ENFORCEMENT OF CERTAIN RIGHTS BY HOLDERS OF THE PREFERRED SECURITIES

     If an event of default under the indenture has occurred and is continuing
and the event is attributable to the failure by us to pay interest on or
principal of the debentures on the date on which the payment is due and payable,
then a holder of preferred securities may institute a direct action against us
to compel us to make the payment. We may not amend the indenture to remove the
foregoing right to bring a direct action without the prior written consent of
all of the holders of the preferred securities. If the right to bring a direct
action is removed, the trust may become subject to the reporting obligations
under the Securities Exchange Act of 1934.

     The holders of the preferred securities will not be able to exercise
directly any remedies, other than those set forth in the preceding paragraph,
available to the holders of the debentures unless there has been an event of
default under the trust agreement. See "Description of the Preferred Securities
- -- Events of Default; Notice."

CONSOLIDATION, MERGER, SALE OF ASSETS AND OTHER TRANSACTIONS

     We may not consolidate with or merge into any other entity or convey or
transfer our properties and assets substantially as an entirety to any entity,
and no entity may be consolidated with or merged into us

                                       35
<PAGE>   41

or sell, convey, transfer or otherwise dispose of its properties and assets
substantially as an entirety to us, unless:

     - if we consolidate with or merge into another person or convey or transfer
       our 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 the successor person expressly
       assumes by supplemental indenture our obligations on the debentures;

     - immediately after the transaction, no event of default under the
       indenture, and no event which, after notice or lapse of time, or both,
       would become an event of default under the indenture, has occurred and is
       continuing; and

     - other conditions as prescribed in the indenture are met.

SATISFACTION AND DISCHARGE

     The indenture will cease to be of further effect and we will be deemed to
have satisfied and discharged our obligations under the indenture when all
debentures not previously delivered to the indenture trustee for cancellation:

     - have become due and payable;

     - will become due and payable at their stated maturity within one year or
       are to be called for redemption within one year, and we deposit or cause
       to be deposited with the indenture trustee funds, in trust, for the
       purpose and in an amount sufficient to pay and discharge the entire
       indebtedness on the debentures not previously delivered to the indenture
       trustee for cancellation, for the principal and interest due to the date
       of the deposit or to the stated maturity or redemption date, as the case
       may be.

     We may still be required to provide officers' certificates, opinions of
counsel and pay fees and expenses due after these events occur.

GOVERNING LAW

     The indenture and the debentures will be governed by and construed in
accordance with the law State of Illinois.

INFORMATION CONCERNING THE INDENTURE TRUSTEE

     The indenture trustee is subject to all the duties and responsibilities
specified with respect to an indenture trustee under the Trust Indenture Act.
Subject to these provisions, the indenture trustee is under no obligation to
exercise any of the powers vested in it by the indenture at the request of any
holder of debentures, unless offered reasonable indemnity by the holder against
the costs, expenses and liabilities which might be incurred. The indenture
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 indenture
trustee reasonably believes that repayment or adequate indemnity is not
reasonably assured to it.

MISCELLANEOUS

     We have agreed, pursuant to the indenture, for so long as preferred
securities remain outstanding:

     - to maintain directly or indirectly 100% ownership of the common
       securities of the trust, except that certain successors that are
       permitted pursuant to the indenture may succeed to our ownership of the
       common securities;

     - not to voluntarily terminate, wind up or liquidate the trust without
       prior approval of the Federal Reserve, if required;

                                       36
<PAGE>   42

     - to use our reasonable efforts to cause the trust (a) to remain a business
       trust (and to avoid involuntary termination, winding up or liquidation),
       except in connection with a distribution of debentures, the redemption of
       all of the trust securities of the trust or mergers, consolidations or
       amalgamations, each as permitted by the trust agreement; and (b) to
       otherwise continue not to be treated as an association taxable as a
       corporation or partnership for federal income tax purposes; and

     - to use our reasonable efforts to cause each holder of trust securities to
       be treated as owning an individual beneficial interest in the debentures.

                              BOOK-ENTRY ISSUANCE

GENERAL

     DTC will act as securities depositary for the preferred securities and may
act as securities depositary for all of the debentures in the event of the
distribution of the debentures to the holders of preferred securities. Except as
described, the preferred securities will be issued only as registered securities
in the name of Cede & Co. (DTC's nominee). One or more global preferred
securities will be issued for the preferred securities and will be deposited
with DTC.

     DTC is a limited purpose trust company organized under New York banking
law, a "banking organization" within the meaning of the New York banking law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to Section 17A of the Securities Exchange Act of 1934. DTC
holds securities that its participants deposit with DTC. DTC also facilitates
the settlement among participants of securities transactions, such as transfers
and pledges, in deposited securities through electronic computerized book-entry
changes in participants' accounts, thereby eliminating the need for physical
movement of securities certificates. Direct participants include securities
brokers and dealers, banks, trust companies, clearing corporations and certain
other organizations. DTC is owned by a number of its direct participants and by
the New York Stock Exchange, the American Stock Exchange and the National
Association of Securities Dealers, Inc. Access to the DTC system is also
available to indirect participants, such as securities brokers and dealers,
banks and trust companies that clear through or maintain custodial relationships
with direct participants, either directly or indirectly. The rules applicable to
DTC and its participants are on file with the SEC.

     Purchases of preferred securities within the DTC system must be made by or
through direct participants, which will receive a credit for the preferred
securities on DTC's records. The ownership interest of each actual purchaser of
each preferred security ("beneficial owner") is in turn to be recorded on the
direct and indirect participants' records. Beneficial owners will not receive
written confirmation from DTC of their purchases, but beneficial owners are
expected to receive written confirmations providing details of the transactions,
as well as periodic statements of their holdings, from the direct or indirect
participants through which the beneficial owners purchased preferred securities.
Transfers of ownership interests in the preferred securities are to be
accomplished by entries made on the books of participants acting on behalf of
beneficial owners. Beneficial owners will not receive certificates representing
their ownership interest in preferred securities, except if use of the
book-entry-only system for the preferred securities is discontinued.

     DTC will have no knowledge of the actual beneficial owners of the preferred
securities; DTC's records reflect only the identity of the direct participants
to whose accounts the preferred securities are credited, which may or may not be
the beneficial owners. The participants will remain responsible for keeping
account of their holdings on behalf of their customers.

     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that we believe to be accurate, but we and the
trust assume no responsibility for the accuracy thereof. Neither we nor the
trust have any responsibility for the performance by DTC or its participants of

                                       37
<PAGE>   43

their respective obligations as described in this prospectus or under the rules
and procedures governing their respective operations.

NOTICES AND VOTING

     Conveyance of notices and other communications by DTC to direct
participants, by direct participants to indirect participants, and by direct and
indirect participants to beneficial owners will be governed by arrangements
among them, subject to any statutory or regulatory requirements as may be in
effect from time to time.

     Redemption notices will be sent to Cede & Co. as the registered holder of
the preferred securities. If less than all of the preferred securities are being
redeemed, the amount to be redeemed will be determined in accordance with the
trust agreement.

     Although voting with respect to the preferred securities is limited to the
holders of record of the preferred securities, in those instances in which a
vote is required, neither DTC nor Cede & Co. will itself consent or vote with
respect to preferred securities. Under its usual procedures, DTC would mail an
omnibus proxy to the property trustee as soon as possible after the record date.
The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those
direct participants to whose accounts the preferred securities are credited on
the record date.

DISTRIBUTION OF FUNDS

     The property trustee will make distribution payments on the preferred
securities to DTC. DTC's practice is to credit direct participants' accounts on
the relevant payment date in accordance with their respective holdings shown on
DTC's records unless DTC has reason to believe that it will not receive payments
on the payment date. Payments by participants to beneficial owners will be
governed by standing instructions and customary practices and will be the
responsibility of the participant and not of DTC, the property trustee, the
trust or us, subject to any statutory or regulatory requirements as may be in
effect from time to time. Payment of distributions to DTC is the responsibility
of the property trustee, disbursement of the payments to direct participants is
the responsibility of DTC, and disbursements of the payments to the beneficial
owners is the responsibility of direct and indirect participants.

SUCCESSOR DEPOSITARIES AND TERMINATION OF BOOK-ENTRY SYSTEM

     DTC may discontinue providing its services with respect to any of the
preferred securities at any time by giving reasonable notice to the property
trustee or us. If no successor securities depositary is obtained, definitive
certificates representing the preferred securities are required to be printed
and delivered. We also have the option to discontinue use of the system of
book-entry transfers through DTC (or a successor depositary). After an event of
default under the indenture, the holders of a majority in liquidation amount of
preferred securities may determine to discontinue the system of book-entry
transfers through DTC. In these events, definitive certificates for the
preferred securities will be printed and delivered.

                          DESCRIPTION OF THE GUARANTEE

     The preferred securities guarantee agreement will be executed and delivered
by us concurrently with the issuance of the preferred securities for the benefit
of the holders of the preferred securities. The guarantee agreement will be
qualified as an indenture under the Trust Indenture Act. Wilmington Trust
Company, the guarantee trustee, will act as trustee for purposes of complying
with the provisions of the Trust Indenture Act, and will also hold the guarantee
for the benefit of the holders of the preferred securities. Prospective
investors are urged to read the form of the guarantee agreement, which has been
filed as an exhibit to the registration statement of which this prospectus forms
a part.

                                       38
<PAGE>   44

GENERAL

     We agree to pay in full on a subordinated basis, to the extent described in
the guarantee agreement, the guarantee payments (as defined below) to the
holders of the preferred securities, as and when due, regardless of any defense,
right of set-off or counterclaim that the trust may have or assert other than
the defense of payment.

     The following payments with respect to the preferred securities are called
the "guarantee payments" and, to the extent not paid or made by the trust and to
the extent that the trust has funds available for those distributions, will be
subject to the guarantee:

     - any accumulated and unpaid distributions required to be paid on the
       preferred securities;

     - with respect to any preferred securities called for redemption, the
       redemption price; and

     - upon a voluntary or involuntary dissolution, winding up or termination of
       the trust (other than in connection with the distribution of debentures
       to the holders of preferred securities in exchange for preferred
       securities), the lesser of:

      (a) the amount of the liquidation distribution; and

      (b) the amount of assets of the trust remaining available for distribution
          to holders of preferred securities in liquidation of the trust.

We may satisfy our obligations to make a guarantee payment by making a direct
payment of the required amounts to the holders of the preferred securities or by
causing the trust to pay the amounts to the holders.

     The guarantee agreement is a guarantee, on a subordinated basis, of the
guarantee payments, but the guarantee only applies to the extent the trust has
funds available for those distributions. If we do not make interest payments on
the debentures purchased by the trust, the trust will not have funds available
to make the distributions and will not pay distributions on the preferred
securities.

STATUS OF THE GUARANTEE

     The guarantee constitutes our unsecured obligation that ranks subordinate
and junior in right of payment to all of our senior and subordinated debt in the
same manner as the debentures and senior to our capital stock. We expect to
incur additional indebtedness in the future, although we have no specific plans
in this regard presently, and neither the indenture nor the trust agreement
limits the amounts of the obligations that we may incur.

     The guarantee constitutes a guarantee of payment and not of collection. If
we fail to make guarantee payments when required, holders of preferred
securities may institute a legal proceeding directly against us to enforce their
rights under the guarantee without first instituting a legal proceeding against
any other person or entity.

     The 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 of the
debentures to the holders of the preferred securities. Because we are a bank
holding company, our right to participate in any distribution of assets of any
subsidiary upon the subsidiary's liquidation or reorganization or otherwise is
subject to the prior claims of creditors of that subsidiary, except to the
extent we may be recognized as a creditor of that subsidiary. Our obligations
under the guarantee, therefore, will be effectively subordinated to all existing
and future liabilities of our subsidiaries, and claimants should look only to
our assets for payments under the guarantee.

AMENDMENTS AND ASSIGNMENT

     Except with respect to any changes that do not materially adversely affect
the rights of holders of the preferred securities, in which case no vote will be
required, the guarantee may be amended only with the

                                       39
<PAGE>   45

prior approval of the holders of a majority of the aggregate liquidation amount
of the outstanding preferred securities. See "Description of the Preferred
Securities -- Voting Rights; Amendment of Trust Agreement."

EVENTS OF DEFAULT; REMEDIES

     An event of default under the guarantee agreement will occur upon our
failure to make any required guarantee payments or to perform any other
obligations under the guarantee. The holders of a majority in aggregate
liquidation amount of the preferred 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 and may direct the exercise of
any power conferred upon the guarantee trustee under the guarantee agreement.

     Any holder of preferred securities may institute and prosecute a legal
proceeding directly against us 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.

     We are required to provide to the guarantee trustee annually a certificate
as to whether or not we are in compliance with all of the conditions and
covenants applicable to us under the guarantee agreement.

TERMINATION OF THE GUARANTEE

     The guarantee will terminate and be of no further force and effect upon:

     - full payment of the redemption price of the preferred securities;

     - full payment of the amounts payable upon liquidation of the trust; or

     - distribution of the debentures to the holders of the preferred
       securities.

If at any time any holder of the preferred securities must restore payment of
any sums paid under the preferred securities or the guarantee, the guarantee
will continue to be effective or will be reinstated with respect to such
amounts.

INFORMATION CONCERNING THE GUARANTEE TRUSTEE

     The guarantee trustee, other than during the occurrence and continuance of
our default in performance of the guarantee, undertakes to perform only those
duties as are specifically set forth in the guarantee. When an event of default
has occurred and is continuing, the guarantee trustee 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 those provisions, the guarantee
trustee is under no obligation to exercise any of the powers vested in it by the
guarantee at the request of any holder of any preferred securities unless it is
offered reasonable indemnity against the costs, expenses and liabilities that
might be incurred thereby.

EXPENSE AGREEMENT

     We will, pursuant to the Agreement as to Expenses and Liabilities entered
into by us and the trust under the trust agreement, irrevocably and
unconditionally guarantee to each person or entity to whom the trust becomes
indebted or liable, the full payment of any costs, expenses or liabilities of
the trust, other than obligations of the trust to pay to the holders of the
preferred securities or other similar interests in the trust of the amounts due
to the holders pursuant to the terms of the preferred securities or other
similar interests, as the case may be. Third party creditors of the trust may
proceed directly against us under the expense agreement, regardless of whether
they had notice of the expense agreement.

GOVERNING LAW

     The guarantee will be governed by the laws of the State of Illinois.

                                       40

                RELATIONSHIP AMONG THE PREFERRED SECURITIES, THE
                          DEBENTURES AND THE GUARANTEE

FULL AND UNCONDITIONAL GUARANTEE

     We irrevocably guarantee, as and to the extent described in this
prospectus, payments of distributions and other amounts due on the preferred
securities, to the extent the trust has funds available for the payment of these
amounts. We and the trust believe that, taken together, our obligations under
the debentures, the indenture, the trust agreement, the expense agreement and
the guarantee agreement provide, in the aggregate, a full, irrevocable and
unconditional guarantee, on a subordinated basis, of payment of distributions
and other amounts due on the preferred securities. No single document standing
alone or operating in conjunction with fewer than all of the other documents
constitutes a guarantee. It is only the combined operation of these documents
that has the effect of providing a full, irrevocable and unconditional guarantee
of the obligations of the trust under the preferred securities.

     If and to the extent that we do not make payments on the debentures, the
trust will not pay distributions or other amounts due on the preferred
securities. The guarantee does not cover payment of distributions when the trust
does not have sufficient funds to pay the distributions. In this event, the
remedy of a holder of preferred securities is to institute a legal proceeding
directly against us for enforcement of payment of the distributions to the
holder. Our obligations under the guarantee are subordinated and junior in right
of payment to all of our other indebtedness.

SUFFICIENCY OF PAYMENTS

     As long as payments of interest and other payments are made when due on the
debentures, these payments will be sufficient to cover distributions and other
payments due on the preferred securities, primarily because:

     - the aggregate principal amount of the debentures will be equal to the sum
       of the aggregate stated liquidation amount of the trust securities;

     - the interest rate and interest and other payment dates on the debentures
       will match the distribution rate and distribution and other payment dates
       for the preferred securities;

     - we will pay for any and all costs, expenses and liabilities of the trust,
       except the obligations of the trust to pay to holders of the preferred
       securities the amounts due to the holders pursuant to the terms of the
       preferred securities; and

     - the trust will not engage in any activity that is not consistent with the
       limited purposes of the trust.

ENFORCEMENT RIGHTS OF HOLDERS OF PREFERRED SECURITIES

     A holder of any preferred security may institute a legal proceeding
directly against us to enforce its rights under the guarantee without first
instituting a legal proceeding against the guarantee trustee, the trust or any
other person. A default or event of default under any of our senior or
subordinated debt would not constitute a default or event of default under the
trust agreement. In the event, however, of payment defaults under, or
acceleration of, our senior or subordinated debt, the subordination provisions
of the indenture provide that no payments may be made in respect of the
debentures until the obligations have been paid in full or any payment default
has been cured or waived. Failure to make required payments on the debentures
would constitute an event of default under the trust agreement.

LIMITED PURPOSE OF THE TRUST

     The preferred securities evidence preferred undivided beneficial interests
in the assets of the trust. The trust exists for the exclusive purposes of
issuing the trust securities, investing the proceeds thereof in debentures and
engaging in only those other activities necessary, advisable or incidental
thereto. A principal difference between the rights of a holder of a preferred
security and the rights of a holder of a debenture is that a holder of a
debenture is entitled to receive from us the principal amount of and interest
                                       41
<PAGE>   47

accrued on debentures held, while a holder of preferred securities is entitled
to receive distributions from the trust (or from us under the guarantee) if and
to the extent the trust has funds available for the payment of the
distributions.

RIGHTS UPON TERMINATION

     Upon any voluntary or involuntary termination, winding-up or liquidation of
the trust involving the liquidation of the debentures, the holders of the
preferred securities will be entitled to receive, out of assets held by the
trust, the liquidation distribution in cash. See "Description of the Preferred
Securities -- Liquidation Distribution Upon Termination."

     Upon our voluntary or involuntary liquidation or bankruptcy, the property
trustee, as holder of the debentures, would be a subordinated creditor of ours.
Therefore, the property trustee would be subordinated in right of payment to all
of our senior and subordinated debt, but is entitled to receive payment in full
of principal and interest before any of our stockholders receive payments or
distributions. Since we are the guarantor under the guarantee and have agreed to
pay for all costs, expenses and liabilities of the trust other than the
obligations of the trust to pay to holders of the preferred securities the
amounts due to the holders pursuant to the terms of the preferred securities,
the positions of a holder of the preferred securities and a holder of the
debentures relative to our other creditors and to our stockholders in the event
of liquidation or bankruptcy are expected to be substantially the same.

                        FEDERAL INCOME TAX CONSEQUENCES

GENERAL

     The following summary of the material federal income tax considerations
that may be relevant to the purchasers of preferred securities represents the
opinion of Vedder, Price, Kaufman & Kammholz, counsel to Midwest Banc Holdings
and the trust insofar as it relates to matters of law and legal conclusions. The
conclusions expressed herein are based upon current provisions of the Internal
Revenue Code of 1986, regulations thereunder and current administrative rulings
and court decisions, all of which are subject to change at any time, with
possible retroactive effect. Subsequent changes may cause tax consequences to
vary substantially from the consequences described below. Furthermore, the
authorities on which the following 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 preferred securities may
differ from the treatment described below.

     No attempt has been made in the following discussion to comment on all
federal income tax matters affecting purchasers of preferred securities.
Moreover, the discussion generally focuses on holders of preferred securities
who are individual citizens or residents of the United States and who acquire
preferred securities on their original issue at their offering price and hold
preferred securities as capital assets. The discussion has only limited
application to dealers in securities, corporations, estates, trusts or
nonresident aliens and does not address all the tax consequences that may be
relevant to holders who may be subject to special tax treatment, such as, for
example, banks, thrifts, real estate investment trusts, regulated investment
companies, insurance companies, dealers in securities or currencies, tax-exempt
investors or persons that will hold the preferred securities as a position in a
"straddle," as part of a "synthetic security" or "hedge," as part of a
"conversion transaction" or other integrated investment, or as other than a
capital asset. The following summary also does not address the tax consequences
to persons that have a functional currency other than the U.S. dollar or the tax
consequences to shareholders, partners or beneficiaries of a holder of preferred
securities. Further, it does not include any description of any alternative
minimum tax consequences or the tax laws of any state or local government or of
any foreign government that may be applicable to the preferred securities.
Accordingly, each prospective investor should consult, and should rely
exclusively on, the investor's own tax advisors in analyzing the federal, state,
local and foreign tax consequences of the purchase, ownership or disposition of
preferred securities.

<PAGE>   48

CLASSIFICATION OF THE DEBENTURES


     Based on the advice of counsel, we intend to take the position that the
debentures will be classified for federal income tax purposes as indebtedness of
Midwest Banc Holdings under current law, and, by acceptance of a preferred
security, each holder covenants to treat the debentures as indebtedness and the
preferred securities as evidence of an indirect beneficial ownership interest in
the debentures. No assurance can be given, however, that this position will not
be challenged by the Internal Revenue Service or, if challenged, that it will
not be successful. The remainder of this discussion assumes that the debentures
will be classified for federal income tax purposes as indebtedness of Midwest
Banc Holdings.


CLASSIFICATION OF THE TRUST


     With respect to the preferred securities, Vedder, Price, Kaufman &
Kammholz, counsel for Midwest Banc Holdings and the trust, has rendered its
opinion generally to the effect that, under then current law and assuming full
compliance with the terms of the trust agreement and indenture, the trust will
be classified for federal income tax purposes as a grantor trust and not as an
association taxable as a corporation. Accordingly, for federal income tax
purposes, each holder of preferred securities generally will be treated as
owning an undivided beneficial interest in the debentures, and each holder will
be required to include in its gross income any interest with respect to the
debentures at the time such interest is accrued or is received, in accordance
with the holder's method of accounting. If the debentures were determined to be
subject to the original issue discount ("OID") rules, each holder would instead
be required to include in its gross income any OID accrued with respect to its
allocable share of the debentures whether or not cash were actually distributed
to the holder.


INTEREST PAYMENT PERIOD AND ORIGINAL ISSUE DISCOUNT

     United States persons (including cash basis taxpayers) 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 the debentures
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
debentures, we have concluded that the likelihood of exercising our option to
defer payments of interest is remote. This is in part because we have a history
of declaring dividends on our common stock and we would be unable to continue
paying these dividends, which could adversely affect the market for our common
stock, if we deferred our payments under the debentures.

     If the option to defer any payment of interest was determined not to be
"remote" or if Midwest Banc Holdings actually exercises its option to defer the
payment of interest, the 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 would thereafter be treated as OID as long as the debentures
remained outstanding. In such event, all of a United States person's taxable
interest income in respect of the 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 preferred securities would be required
to include such OID in gross income even though Midwest Banc Holdings would not
make any actual cash payments during an extension period.

     The above information is 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.

                                       43
<PAGE>   49

     Because income on the preferred securities will constitute interest,
corporate holders of preferred securities will not be entitled to a
dividends-received deduction with respect to any income recognized with respect
to the preferred securities.

MARKET DISCOUNT AND ACQUISITION PREMIUM

     Holders of preferred securities other than a holder who purchased the
preferred securities upon original issuance may be considered to have acquired
their undivided interests in the debentures with "market discount" or
"acquisition premium" as these phrases are defined for federal income tax
purposes. Such holders are advised to consult their tax advisors as to the
income tax consequences of the acquisition, ownership and disposition of the
preferred securities.

RECEIPT OF DEBENTURES OR CASH UPON LIQUIDATION OF THE TRUST

     Under the circumstances described under "Description of the Preferred
Securities -- Redemption or Exchange" and "-- Liquidation Distribution Upon
Termination," the debentures may be distributed to holders of preferred
securities upon a liquidation of the trust. Under current federal income tax
law, such a distribution would be treated as a nontaxable event to the holder
and would result in the holder having an aggregate tax basis in the debentures
received in the liquidation equal to the holder's aggregate tax basis in the
preferred securities immediately before the distribution. A holder's holding
period in debentures received in liquidation of the trust would include the
period for which the holder held the preferred securities.

     If, however, a Tax Event occurs which results in the trust being treated as
an association taxable as a corporation, the distribution would likely
constitute a taxable event to holders of the preferred securities. Under certain
circumstances described herein, the debentures may be redeemed for cash and the
proceeds of the redemption distributed to holders in redemption of their
preferred securities. Under current law, such a redemption should, to the extent
that it constitutes a complete redemption, constitute a taxable disposition of
the redeemed preferred securities, and, for federal income tax purposes, a
holder should recognize gain or loss as if the holder sold the preferred
securities for cash.

DISPOSITION OF PREFERRED SECURITIES

     A holder that sells preferred securities will recognize gain or loss equal
to the difference between the amount realized on the sale of the preferred
securities and the holder's adjusted tax basis in the preferred securities. A
holder's adjusted tax basis in the preferred securities generally will be its
initial purchase price increased by OID previously includible in the holder's
gross income to the date of disposition and decreased by payments received on
the preferred securities to the date of disposition. A gain or loss of this kind
will generally be a capital gain or loss and will be a long-term capital gain or
loss if the preferred securities have been held for more than one year at the
time of sale.

     The preferred securities may trade at a price that does not accurately
reflect the value of accrued but unpaid interest with respect to the underlying
debentures. A holder that disposes of its preferred securities between record
dates for payments of distributions thereon will be required to include accrued
but unpaid interest on the debentures through the date of disposition in income
as ordinary income, and to add the amount to its adjusted tax basis in its
proportionate share of the underlying debentures deemed disposed of. To the
extent the selling price is less than the holder's adjusted tax basis a holder
will recognize a capital loss. The adjusted basis would include, in the form of
OID, all accrued but unpaid interest. Subject to certain limited exceptions,
capital losses cannot be applied to offset ordinary income for federal income
tax purposes.

EFFECT OF POSSIBLE CHANGES IN TAX LAWS

     Congress and the Clinton Administration have considered certain proposed
tax law changes in the past that would, among other things, generally deny
corporate issuers a deduction for interest in respect of certain debt
obligations if the debt obligations have a maximum term in excess of 15 years
and are not
                                       44
<PAGE>   50

shown as indebtedness on the issuer's applicable consolidated balance sheet.
Other proposed tax law changes would have denied interest deductions if the term
was in excess of 20 years. Although these proposed tax law changes have not been
enacted into law, there can be no assurance that tax law changes will not be
reintroduced into future legislation which, if enacted after the date hereof,
may adversely affect the federal income tax deductibility of interest payable on
the debentures. Accordingly, there can be no assurance that a Tax Event will not
occur. A Tax Event would permit us, upon approval of the Federal Reserve if then
required to cause a redemption of the preferred securities before, as well as
after,             , 2005. See "Description of the Debentures -- Redemption" and
"Description of the Preferred Securities -- Redemption or Exchange -- Redemption
upon a Tax Event, Investment Company Event or Capital Treatment Event."

BACKUP WITHHOLDING AND INFORMATION REPORTING

     The amount of qualified stated interest, or, if applicable, OID, accrued on
the preferred securities held of record by individual citizens or residents of
the United States, or certain trusts, estates and partnerships, will be reported
to the Internal Revenue Service on Forms 1099-INT, or, where applicable, Forms
1099-OID, which forms should be mailed to the holders by January 31 following
each calendar year. Payments made on, and proceeds from the sale of, the
preferred securities may be subject to a "backup" withholding tax (currently at
31%) unless the holder complies with certain identification and other
requirements. Any amounts withheld under the backup withholding rules will be
allowed as a credit against the holder's federal income tax liability, provided
the required information is provided to the Internal Revenue Service.

     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND MAY NOT BE APPLICABLE DEPENDING UPON THE PARTICULAR
SITUATION OF A HOLDER OF PREFERRED SECURITIES. HOLDERS OF PREFERRED SECURITIES
SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES TO THEM
OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE PREFERRED SECURITIES,
INCLUDING THE TAX CONSEQUENCES UNDER STATE, LOCAL, FOREIGN AND OTHER TAX LAWS
AND THE POSSIBLE EFFECTS OF CHANGES IN FEDERAL OR OTHER TAX LAWS.

                              ERISA CONSIDERATIONS

     Employee benefit plans that are subject to the Employee Retirement Income
Security Act of 1974, or Section 4975 of the Internal Revenue Code, generally
may purchase preferred securities, subject to the investing fiduciary's
determination that the investment in preferred securities satisfies ERISA's
fiduciary standards and other requirements applicable to investments by the
plan.

     In any case, we and/or any of our affiliates may be considered a "party in
interest" (within the meaning of ERISA) or a "disqualified person" (within the
meaning of Section 4975 of the Internal Revenue Code) with respect to certain
plans. These plans generally include plans maintained or sponsored by, or
contributed to by, any such persons with respect to which we or any of our
affiliates are a fiduciary or plans for which we or any of our affiliates
provide services. The acquisition and ownership of preferred securities by a
plan (or by an individual retirement arrangement or other plans described in
Section 4975(e)(1) of the Internal Revenue Code) with respect to which we or any
of our affiliates are considered a party in interest or a disqualified person
may constitute or result in a prohibited transaction under ERISA or Section 4975
of the Internal Revenue Code, unless the preferred securities are acquired
pursuant to and in accordance with an applicable exemption.

     As a result, plans with respect to which we or any of our affiliates or any
of its affiliates is a party in interest or a disqualified person should not
acquire preferred securities unless the preferred securities are acquired
pursuant to and in accordance with an applicable exemption. Any other plans or
other entities whose assets include plan assets subject to ERISA or Section 4975
of the Internal Revenue Code proposing to acquire preferred securities should
consult with their own counsel.

     The underwriting agreement requires the underwriters to accept and pay for
all of the preferred securities if any are purchased. In addition, the
underwriting agreement requires that certain conditions must be satisfied on the
part of Midwest Banc Holdings and MBHI Capital Trust I before the underwriters
are obligated to purchase the preferred securities. These conditions include the
accuracy of specific representations and warranties and the receipt of opinions
of counsel and reports from accountants as to certain matters relating to

     All of the proceeds to MBHI Capital Trust I will be used to purchase the
junior subordinated debentures from Midwest Banc Holdings. Midwest Banc Holdings
has agreed to pay the underwriters      % of the public offering price per
preferred security, as compensation for arranging the investment in the junior
subordinated debentures.

     The underwriters propose to offer the preferred securities in part directly
to the public at the initial public offering price set forth above, and in part
to securities dealers at this price less a concession not in excess of $     per
preferred security. The underwriters may allow, and the dealers may reallow, a
concession not in excess of $     per preferred security to brokers and dealers.
After the preferred securities are released for sale to the public, the offering
price and other selling terms may from time to time be varied by the
underwriters.

     Midwest Banc Holdings and MBHI Capital Trust I have agreed to indemnify the
underwriters against certain liabilities, including liabilities under the
Securities Act of 1933. Generally, the indemnification provisions in the
underwriting agreement provide for full indemnification of the underwriters in
actions related to the disclosure in this prospectus unless such disclosure was
provided by the underwriters specifically for use in this prospectus.

<PAGE>   52


     In connection with the offering, the underwriters may purchase and sell the
preferred securities in the open market. These transactions may include
over-allotment and stabilizing transactions and purchases to cover syndicate
short positions created in connection with the offering. Stabilizing
transactions consist of bids or purchases for the purpose of preventing or
retarding a decline in the market price of the preferred securities. Syndicate
short positions involve the sale by the underwriters of a greater number of
securities than they agreed to purchase from Midwest Banc Holdings in the
offering. The underwriters also may impose a penalty bid, which means the
syndicate may reclaim selling concessions that had been allocated to syndicate
members or other broker-dealers for preferred securities they were credited for
selling in the offering if those securities are repurchased by the syndicate in
stabilizing or covering transactions. These activities may stabilize, maintain
or otherwise affect the market price of the securities, which may be higher than
the price that might otherwise prevail in the open market. These activities, if
commenced, may be discontinued at any time. These transactions may be effected
in the over-the-counter market or otherwise.



     The underwriters have advised MBHI Capital Trust I that they will not
confirm any sales of preferred securities to any discretionary accounts. In
connection with the offer and sale of the preferred securities, the underwriters
will comply with Rule 2810 under the NASD Conduct Rules.


                                 LEGAL MATTERS

     Legal matters, including matters relating to federal income tax
considerations, for Midwest Banc Holdings and the trust will be passed upon by
Vedder, Price, Kaufman & Kammholz, Chicago, Illinois, counsel to Midwest Banc
Holdings and the trust. Certain legal matters will be passed upon for the
underwriters by Chapman and Cutler, Chicago, Illinois. Vedder, Price, Kaufman &
Kammholz and Chapman and Cutler will rely on the opinion of Richards, Layton &
Finger, P.A. as to matters of Delaware law.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     In accordance with the Delaware General Corporation Law, Sections 11 and 13
of Midwest Banc Holdings' Certificate of Incorporation provide as follows:

          Section 11. The corporation shall, to the full extent permitted by
     Section 145 of the Delaware General Corporation Law, as amended from time
     to time, indemnify all persons who it may indemnify pursuant thereto.

          Section 13. No director of the corporation shall be personally liable
     to the corporation or its stockholders for monetary damages for breach of
     fiduciary duty as a director, provided, however, that this provision shall
     not eliminate or limit the liability of a director (i) for any breach of a
     director's duty of loyalty to the corporation or its stockholders; (ii) for
     acts or omissions not in good faith or which involve intentional misconduct
     or a knowing violation of the law; (iii) under Section 174 of the Delaware
     General Corporation Law; or (iv) for any transaction for which the director
     derived an improper personal benefit.

     Additional provisions regarding indemnification are included in the
Company's By-laws. Article VIII of Midwest Banc Holdings' Bylaws provides as
follows:

          Section 8.1 Indemnification. The Corporation shall indemnify, to the
     full extent that it shall have the power under the Delaware General
     Corporation Law to do so and in a manner permitted by such law, any person
     made or threatened to be made a party to any threatened, pending or
     completed action, suit or proceeding, whether civil, criminal,
     administrative or investigative, by reason of the fact that he is or was a
     director, officer, employee or agent of the Corporation, or is or was
     serving at the request of the Corporation as a director, officer, employee
     or agent of another corporation, partnership, joint venture, trust or other
     enterprise against liabilities and expenses reasonably incurred or paid by
     such person in connection with such action, suit or proceeding. The words
     "liabilities" and "expenses" shall include, without limitations:
     liabilities, losses, damages, judgments, fines, penalties, amounts paid in
     settlement, expenses, attorneys' fees and costs. Expenses incurred in
     defending a civil, criminal, administrative, investigative or other action,
     suit or proceeding may be paid by the Corporation in advance of the final
     disposition of such action, suit or proceeding in accordance with the
     provisions of Section 145 of the Delaware General Corporation Law, as
     amended.

                                      II-1
<PAGE>   56

          The indemnification and advancement of expenses provided by this
     By-law shall not be deemed exclusive of any other rights to which any
     person indemnified may be entitled under any by-law, statute, agreement,
     vote of stockholders, or disinterested directors or otherwise, both as to
     action in his official capacity and as to action in another capacity while
     holding such office, and shall continue as to a person who has ceased to be
     such director, officer, employee or agent and shall inure to the benefit of
     the heirs, executors and administrators of such person.

          The Corporation may purchase and maintain insurance on behalf of any
     person referred to in the preceding paragraph 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 Corporation would have the
     power to indemnify him against such liability under the provisions of this
     By-law or otherwise.

          For purposes of this By-law, reference to "the Corporation" shall
     include, in addition to the resulting corporation, any constituent
     corporation (including any constituent of a constituent) absorbed in a
     consolidation or merger which, if its separate existence had continued,
     would have had power and authority to indemnify its directors, officers and
     employees or agents, so that any person who is or was a director, officer,
     employee or agent of such constituent corporation, or is or was serving at
     the request of such constituent corporation, as director, officer, employee
     or agent of another corporation, partnership, joint venture, trust or other
     enterprise, shall stand in the same position under the provisions of this
     By-law with respect to the resulting or surviving corporation as he would
     have with respect to such constituent corporation if its separate existence
     had continued.

          The provisions of this By-law shall be deemed to be a contract between
     the Corporation and each director, officer, employee and agent who serves
     in any such capacity at any time while this By-law and the relevant
     provisions of the Delaware General Corporation Law, as amended, or other
     applicable law, if any, are in effect, and any repeal or modification of
     any such law or of this By-law shall not affect any rights or obligations
     then existing with respect to any state of facts then or theretofore
     existing or any action, suit or proceeding theretofore or thereafter
     brought or threatened based in whole or in part upon such state of facts.

          For purposes of this By-law, references to "other enterprises" shall
     include employee benefit plans; references to "fines" shall include any
     excise taxes assessed on a person with respect to any employee benefit
     plan; and references to "serving at the request of the corporation" shall
     include any service as a director, officer, employee or agent of the
     corporation which imposes duties on, or involves services by, such
     director, officer, employee or agent with respect to any employee benefit
     plan, its participants, or beneficiaries; and a person who acted in good
     faith and in a manner he reasonably believed to be in the best interest of
     the participants and beneficiaries of an employee benefit plan shall be
     deemed to have acted in a manner not opposed to the best interests of the
     Corporation.

     Midwest Banc Holdings also carries Directors' and Officers' liability
insurance in the amount of $10 million.

     The Amended and Restated Trust Agreement will provide for indemnification
of the Delaware Trustee and each of the administrative trustees by Midwest Banc
Holdings against any loss, damage, claims, liability, penalty or expense of any
kind incurred by the trustees in connection with the performance of their duties
or powers under the agreement in a manner reasonably believed by the trustee to
be within the scope of its authority under the agreement, except that none of
these trustees will be so indemnified for any loss, damage or claim incurred by
reason of such trustee's gross negligence, bad faith or willful misconduct.
Similarly, the agreement provides for indemnification of the Property Trustee
except that the Property Trustee is not indemnified from liability for its own
negligent action, negligent failure to act or willful misconduct. Under the

ITEM 17. UNDERTAKINGS.

     (b) The undersigned Registrants hereby undertake that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Company'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 the
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.

     (h) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the Registrants pursuant to the foregoing provisions, or otherwise, the
Registrants have been advised that in the opinion of the SEC such
indemnification is against public policy as expressed in that Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrants of expenses incurred
or paid by a director, officer, or controlling person of the Registrants 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

                                      II-3
<PAGE>   58

matter has been settled by 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.

     (i) The undersigned registrants hereby undertake that:

          (1) For purposes of determining any liability under the Securities Act
              of 1933, the information omitted from the form of prospectus filed
              as part of this Registration Statement in reliance upon Rule 430A
              and contained in a form of prospectus filed by the Registrant
              pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities
              Act of 1933 shall be deemed to be part of this Registration
              Statement as of the time it was declared effective.

          (2) For the purpose of determining any liability under the Securities
              Act of 1933, each post-effective amendment that contains a form of
              prospectus shall be deemed to be a new registration statement
              relating to the securities offered therein, and the offering of
              such securities at that time shall be deemed to be the initial
              bona fide offering thereof.

Howe Barnes Investments, Inc.
  As Representative of the several Underwriters
  named in Schedule A
135 South LaSalle Street
Chicago, Illinois  60603

Ladies and Gentlemen:

     Midwest Banc Holdings, Inc., a Delaware corporation (the "Company"), and
its subsidiary, Midwest Banc Capital Trust I, a statutory business trust
organized under the Delaware Business Trust Act, as amended (the "Delaware Act")
(the "Trust" and, together with the Company, the "Offerors"), propose, subject
to the terms and conditions stated herein, to issue and sell to you (the
"Underwriters"), an aggregate of $25,000,000, representing 1,000,000 securities
of the Trust's _____% Cumulative Preferred Securities, with a liquidation
preference of $25.00 per preferred security (the "Preferred Securities"). The
Offerors propose that the Trust issue the Preferred Securities pursuant to a
Trust Agreement, as amended and restated, among Wilmington Trust Company, as
Property Trustee and Delaware Trustee, the administrative trustees named therein
(the "Administrative Trustees") and the Company (the "Trust Agreement"). The
Preferred Securities will be guaranteed by the Company with respect to
distributions and payments upon liquidation, redemption and otherwise (the
"Guarantee") pursuant to a Guarantee Agreement (the "Guarantee Agreement"), to
be dated May ___, 2000, between the Company and Wilmington Trust Company, as
trustee (the "Guarantee Trustee"), and entitled to the benefits of certain
backup undertakings described in the Prospectus (as defined herein) with respect
to the Company's agreement pursuant to the Expense Agreement (as defined herein)
to pay all expenses relating to administration of the Trust.

     The proceeds of the sale of the Preferred Securities will be used to
purchase junior subordinated deferrable interest debentures (the "Junior
Subordinated Debentures") issued by the Company pursuant to an Indenture, to be
dated May ___, 2000, between the Company and Wilmington Trust Company, as
trustee (the "Indenture").

     The Offerors have filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (File Nos. 333-36564 and
333-36564-01) and a related preliminary prospectus for the registration of the
Preferred Securities, the Guarantee


<PAGE>   2

and the Junior Subordinated Debentures, under the Securities Act of 1933, as
amended (the "Act") and the Trust Indenture Act of 1939, as amended (the "Trust
Indenture Act") and the rules and regulations thereunder. The registration
statement, as amended, at the time it was declared effective, including the
information (if any) deemed to be part thereof pursuant to Rule 430A under the
Act, is herein referred to as the "Registration Statement." The form of
prospectus first filed by the Offerors with the Commission pursuant to Rules
424(b) and 430A under the Act is referred to herein as the "Prospectus." Each
preliminary prospectus included in the Registration Statement prior to the time
it becomes effective or filed with the Commission pursuant to Rule 424(a) under
the Act is referred to herein as a "Preliminary Prospectus." If the Company
elects to rely on Rule 434 of the Act, all references to "Prospectus" shall be
deemed to include, without limitation, the form of prospectus and the term
sheet, taken together, provided to the Underwriters by the Company in accordance
with Rule 434 of the Act ("Rule 434 Prospectus"). Any registration statement
(including any amendment or supplement thereto or information which is deemed
part thereof) filed by the Company under Rule 462(b) ("Rule 462(b) Registration
Statement") shall be deemed to be part of the "Registration Statement" as
defined herein, and any prospectus (including any amendment or supplement
thereto or information which is deemed part thereof) included in such
registration statement shall be deemed to be part of the "Prospectus," as
defined herein, as appropriate. The Securities Exchange Act of 1934, as amended,
is referred to herein as the "Exchange Act." Any reference herein to any
Preliminary Prospectus or the Prospectus shall be deemed to refer to and include
the documents incorporated by reference therein pursuant to Form S-3 under the
Act (the "Incorporated Documents"), as of the date of such Preliminary
Prospectus or Prospectus, as the case may be. Any document filed by either the
Company or the Trust under the Exchange Act after the effective date of the
Registration Statement or the date of the Prospectus and incorporated by
reference in the Prospectus shall be deemed to be included in the Registration
Statement and the Prospectus as of the date of such filing. Copies of the
Registration Statement, including all exhibits thereto, together with copies of
all documents incorporated by reference therein, any amendments thereto and all
Preliminary Prospectuses have been delivered to you.

     The Offerors hereby confirm their agreement with respect to the purchase of
the Preferred Securities by the Underwriters as follows:

     Section 1. Representations and Warranties of the Offerors. (a) The Offerors
jointly and severally represent and warrant to, and agree with, each of the
Underwriters that:

          (i) The Registration Statement has been declared effective under the
     Act, and no post-effective amendment to the Registration Statement has been
     filed with the Commission as of the date of this Agreement. No stop order
     suspending the effectiveness of the Registration Statement has been issued
     and no proceeding for that purpose has been instituted or threatened by the
     Commission.

          (ii) No order preventing or suspending the use of any Preliminary
     Prospectus has been issued by the Commission, and each Preliminary
     Prospectus, at the time of filing thereof, conformed in all material
     respects to the requirements of the Act and the Trust Indenture Act and the
     rules and regulations of the Commission promulgated thereunder, and did not
     contain an untrue statement of a material fact or omit to state a material
     fact




                                      -2-
<PAGE>   3

     required to be stated therein or necessary to make the statements therein,
     in light of the circumstances under which they were made, not misleading;
     provided, however, that the Offerors make no representation or warranty as
     to information contained in or omitted in reliance upon, and in conformity
     with, written information furnished to the Offerors by or on behalf of any
     Underwriter, expressly for use in the preparation thereof.

          (iii) The Registration Statement conforms, and the Prospectus and any
     amendments or supplements thereto will conform, in all material respects to
     the requirements of the Act and the Trust Indenture Act and the rules and
     regulations thereunder. Neither the Registration Statement nor any
     amendment thereto, and neither the Prospectus nor any supplement thereto,
     contains or will contain, as the case may be, any untrue statement of a
     material fact or omits or will omit to state any material fact required to
     be stated therein or necessary to make the statements therein, in light of
     the circumstances under which they were made, not misleading; provided,
     however, that the Offerors make no representation or warranty as to (i)
     information contained in or omitted from the Registration Statement or the
     Prospectus, or any such amendment or supplement, in reliance upon, and in
     conformity with, written information furnished to the Offerors by or on
     behalf of any Underwriter, expressly for use in the preparation thereof or
     (ii) information in those parts of the Registration Statement which
     constitute the Statement of Eligibility and Qualification ("Form T-1")
     under the Trust Indenture Act.

          The Incorporated Documents, when they were or will be filed with the
     Commission, conformed or will conform in all material respects to the
     requirements of the Exchange Act and none of such documents contained or
     will contain an untrue statement of a material fact or omitted or will omit
     to state a material fact required to be stated therein or necessary to make
     the statements therein not misleading.

          (iv) The Company and each of its subsidiaries have been duly
     incorporated and are validly existing as corporations or banking
     associations in good standing under the laws of their respective places of
     incorporation, with corporate power and authority to own their respective
     properties and conduct their respective businesses as described in the
     Prospectus; the Company and each of its non-bank subsidiaries are duly
     qualified to do business as foreign corporations under the corporation law
     of, and are in good standing as such in, each jurisdiction in which such
     qualification is required except in any such case where the failure to so
     qualify or be in good standing would not have a material adverse effect
     upon the condition (financial or otherwise) or results of operations of the
     Company and its subsidiaries taken as a whole; and no proceeding of which
     the Company has knowledge has been instituted in any such jurisdiction,
     revoking, limiting or curtailing, or seeking to revoke, limit or curtail,
     such power and authority or qualification.

          (v) (A) The Trust has been duly created and is validly existing in
     good standing as a business trust under the Delaware Act with full trust
     power and authority to own property and to conduct its business as
     described in the Registration Statement and Prospectus and is authorized to
     do business in each jurisdiction in which such qualification is required,
     except where the failure to so qualify would not have a material adverse

     It is understood that any Underwriter may (but shall not be obligated to)
make payment to the Company on behalf of the other Underwriter for the Preferred
Securities to be purchased by such Underwriter. Any such payment shall not
relieve such other Underwriter of any of its obligations hereunder. Nothing
herein contained shall constitute the Underwriters an unincorporated association
or partner with either or both Offerors.

     Section 3. Offering by Underwriters. (a) It is understood that the several
Underwriters propose to make a public offering of the Preferred Securities as
soon as the Underwriters deem it advisable to do so. The Preferred Securities
are to be initially offered to the public at the initial public offering price
set forth in the Prospectus. The Underwriters may from time to time thereafter
change the public offering price and other selling terms.

     (b) The Representative, on behalf of the several Underwriters, represents
and warrants to the Company that the information set forth (i) on the cover page
of the Prospectus with respect to price, underwriting compensation and terms of
the offering and (ii) under "Underwriting" in the Prospectus was furnished to
the Company by and on behalf of the Underwriters for use in connection with the
preparation of the Registration Statement and is correct and complete in all
material respects.

     Section 4. Covenants of the Offerors. The Offerors jointly and severally
covenant and agree with the several Underwriters that:

          (a) The Company and the Administrative Trustees on behalf of the Trust
     will prepare and timely file with the Commission under Rule 424(b) under
     the Act a Prospectus containing information previously omitted at the time
     of effectiveness of the Registration Statement in reliance on Rule 430A
     under the Act, and will not file any amendment to the Registration
     Statement or supplement to the Prospectus of which the Underwriters shall
     not previously have been advised and furnished with a copy and as to which
     the Underwriters shall have reasonably objected in writing promptly after
     reasonable notice thereof or which is not in compliance with the Act or the
     rules and regulations thereunder.

          (b) If the Offerors elect to rely on Rule 434 of the Act, the Offerors
     will prepare a term sheet that complies with the requirements of Rule 434.
     If the Offerors elect not to rely on Rule 434, the Offerors will provide
     the Underwriters with copies of the form of prospectus, in such numbers as
     the Underwriters may reasonably request, and file with the Commission such
     prospectus in accordance with Rule 424(b) of the Act by the close of
     business in New York City on the second business day immediately succeeding
     the date of pricing of the offering of the Preferred Securities (the
     "Pricing Date"). If the Offerors elect to rely on Rule 434, the Offerors
     will provide the Underwriters with copies of the form of Rule 434
     Prospectus, in such numbers as the Underwriters may reasonably request, by
     the close of business in New York on the business day immediately
     succeeding the Pricing Date.

<PAGE>   13

          (c) The Offerors will advise the Underwriters promptly of any request
     of the Commission for amendment of the Registration Statement or for
     supplement to the Prospectus or for any additional information, or of the
     issuance by the Commission of any stop order suspending the effectiveness
     of the Registration Statement or the use of the Prospectus, of the
     suspension of the qualification of the Preferred Securities for offering or
     sale in any jurisdiction, or of the institution or threatening of any
     proceedings for that purpose, and the Offerors will use their best efforts
     to prevent the issuance of any such stop order preventing or suspending the
     use of the Prospectus or suspending such qualification and to obtain as
     soon as possible the lifting thereof, if issued.

          (d) The Offerors will cooperate with you and your counsel in order to
     qualify the Preferred Securities for sale under the securities laws of such
     jurisdictions as the Underwriters may reasonably have designated and to
     continue such qualifications in effect for so long as the Underwriters may
     reasonably request for distribution of the Preferred Securities (or obtain
     exemptions from the application of such laws). The Offerors will, from time
     to time, prepare and file such statements, reports and other documents as
     may be requested by the Underwriters for that purpose.

          (e) The Offerors will furnish the Underwriters with as many copies of
     any Preliminary Prospectus as the Underwriters may reasonably request and,
     during the period when delivery of a prospectus is required under the Act,
     the Offerors will furnish the Underwriters with as many copies of the
     Prospectus in final form, or as thereafter amended or supplemented, as the
     Underwriters may, from time to time, reasonably request. The Offerors will
     deliver to the Underwriters, at or before the Closing Date, two signed
     copies of the Registration Statement and all amendments thereto including
     all exhibits filed therewith, together with the Incorporated Documents, and
     will deliver to the Underwriters such number of conformed copies of the
     Registration Statement, without exhibits, and of all amendments thereto,
     together with the Incorporated Documents, as the Underwriters may
     reasonably request.

          (f) If at any time when a prospectus relating to the Preferred
     Securities is required to be delivered under the Act any event occurs as a
     result of which the Prospectus, including any amendments or supplements,
     would include an untrue statement of a material fact, or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein, in the light of the circumstances under which they were
     made, not misleading, or if it is necessary at any time to amend the
     Prospectus, including any amendments or supplements thereto and including
     any revised prospectus which the Offerors propose for use by the
     Underwriters in connection with the offering of the Preferred Securities
     which differs from the prospectus on file with the Commission at the time
     of effectiveness of the Registration Statement, whether or not such revised
     prospectus is required to be filed pursuant to Rule 424(b) to comply with
     the Act, the Offerors promptly will advise you thereof and will promptly
     prepare and file with the Commission an amendment or supplement which will
     correct such statement or omission or an amendment which will effect such
     compliance; and, in case any Underwriter is required to deliver a
     prospectus nine months or more after the effective date of the Registration
     Statement, the Offerors upon request, but at the expense of such


                                      -13-
<PAGE>   14

     Underwriter, will prepare promptly such prospectus or prospectuses as may
     be necessary to permit compliance with the requirements of Section 10(a)(3)
     of the Act.

          (g) Not later than September 1, 2001 the Company will make generally
     available to its security holders an earnings statement (which need not be
     audited) covering a period of at least 12 months beginning after the
     effective date of the Registration Statement, which will satisfy the
     provisions of the last paragraph of Section 11(a) of the Act.

          (h) During the period of five years hereafter, the Company will
     furnish you with a copy (i) as soon as practicable after the filing
     thereof, of each report filed by the Company with the Commission, any
     securities exchange or the NASD; (ii) as soon as practicable after the
     release thereof, of each material press release in respect of the Company;
     and (iii) as soon as available, of each report of the Company mailed to
     stockholders.

          (i) The Offerors will use the net proceeds received by it from the
     sale of the Preferred Securities in the manner specified in the Prospectus.

          (j) If, at the time of effectiveness of the Registration Statement,
     any information shall have been omitted therefrom in reliance upon Rule
     430A and/or Rule 434, then on the Pricing Date, the Offerors will prepare,
     and file or transmit for filing with the Commission in accordance with such
     Rule 430A, Rule 424(b) and/or Rule 434, copies of an amended Prospectus,
     or, if required by such Rule 430A and/or Rule 434, a post-effective
     amendment to the Registration Statement (including an amended Prospectus),
     containing all information so omitted. If required, the Offerors will
     prepare and file, or transmit for filing, a Rule 462(b) Registration
     Statement not later than the date of the execution of the Pricing
     Agreement. If a Rule 462(b) Registration Statement is filed, the Offerors
     shall make payment of, or arrange for payment of, the additional
     registration fee owing to the Commission required by Rule 111.

          (k) The Offerors will comply with all registration, filing and
     reporting requirements of the Exchange Act and the American Stock Exchange.

refusal or inability on the part of the Offerors to perform any undertaking or
satisfy any condition of this Agreement or to comply with any of the terms
hereof on either of their parts to be performed, unless such failure to satisfy
said condition or to comply with said terms shall be due to the default or
omission of any Underwriter, then the Offerors promptly upon request by the
Underwriters shall reimburse the several Underwriters for all actual,
accountable out-of-pocket expenses, including fees and disbursements of counsel

          (b) The Underwriters shall have received on the Closing Date the
     opinion of Vedder, Price, Kaufman & Kammholz, counsel for the Offerors,
     dated the Closing Date, addressed to the Underwriters, to the effect that:

               (i) (A) the Company is validly existing as a corporation in good
          standing under the laws of the State of Delaware with corporate power
          and authority to own its properties and conduct its business as
          described in the Prospectus; and, to the best of such counsel's
          knowledge the Company is duly qualified to do business as a foreign
          corporation under the corporation law of, and is in good standing as
          such in, every jurisdiction where such qualification is required
          except where the failure so to qualify would not have a material
          adverse effect upon the condition (financial or otherwise) or results
          of operations of the Company and its subsidiaries taken as a whole;

                   (B) an opinion to the same general effect as clause (A) of
          this subparagraph (i) in respect of each non-bank subsidiary of the
          Company;

               (ii) the Company owns directly or indirectly 100 percent of the
          outstanding capital stock of each subsidiary;

               (iii) the issued and outstanding capital stock of the Company has
          been duly authorized and validly issued and is fully paid and
          nonassessable;

               (iv) the Registration Statement has become effective under the
          Act, and, to the best knowledge of such counsel, no stop order
          suspending the effectiveness of the Registration Statement has been
          issued and no proceedings for that purpose have been instituted or are
          pending or contemplated under the Act, and the Registration Statement
          (including the information deemed to be part of the Registration
          Statement at the time of effectiveness pursuant to Rule 430A(b) and/or
          Rule 434, if applicable), the Prospectus and each amendment or
          supplement thereto (except for the financial statements and other
          statistical or financial data included therein as to which such
          counsel need express no opinion) comply as to form in all material
          respects with the requirements of the Act; all documents incorporated
          by reference in the Prospectus, when they were filed with the
          Commission, complied as to form in all material respects with the

          believe that any of such documents, when they were so filed, contained
          an untrue statement of a material fact or omitted to state a material
          fact necessary in order to make the statements therein, in the light
          of the circumstances under which such statements were made when such
          documents were so filed, not misleading, such counsel need express no
          opinion as to the financial statements or other financial or
          statistical data contained in any such document); such counsel have no
          reason to believe that either the Registration Statement (including
          the information deemed to be part of the Registration Statement at the
          time of effectiveness pursuant to Rule 430A(b) and/or Rule 434, if
          applicable) or the Prospectus, or the Registration Statement or the
          Prospectus as amended or supplemented (except as aforesaid), as of
          their

          respective effective or issue dates, contained any untrue statement of
          a material fact or omitted to state a material fact required to be
          stated therein or necessary to make the statements therein not
          misleading or that the Prospectus as amended or supplemented, if
          applicable, as of the issue date and as of the Closing Date, contained
          any untrue statement of a material fact or omitted to state any
          material fact necessary to make the statements therein not misleading
          in light of the circumstances under which they were made (except for
          the financial statements and other statistical or financial data
          included therein as to which such counsel need express no opinion);
          and such counsel does not know of any legal or governmental
          proceedings pending or threatened required to be described in the
          Prospectus which are not described as required, nor of any contracts
          or documents of a character required to be described in the
          Registration Statement or Prospectus or to be filed as exhibits to the
          Registration Statement which are not described or filed, as required;

               (v) the statements under the captions "Description of the Trust,"
          "Description of the Preferred Securities," "Description of the
          Debentures," "Book-Entry Issuance," "Description of the Guarantee,"
          "Relationship Among the Preferred Securities, the Debentures and the
          Guarantee" and "Federal Income Tax Consequences" in the Prospectus,
          insofar as such statements constitute a summary of documents referred
          to therein or matters of law, are accurate summaries and fairly
          present, in all material respects, the information called for with
          respect to such documents and matters;

               (vi) the holders of the Company's outstanding securities are not
          entitled to any preemptive or other rights to subscribe for the Junior
          Subordinated Debentures or the Preferred Securities under the
          Company's bylaws and, to the knowledge of such counsel, no such rights
          exist under any other agreement or arrangement;

               (vii) all of the issued and outstanding Common Securities of the
          Trust are owned by the Company free and clear of any security
          interest, mortgage, pledge, lien, encumbrance, claim or equitable
          right;

               (viii) the Trust Agreement, the Indenture, the Guarantee, the
          Form T-1 Statement of Eligibility of Wilmington Trust Company to act
          as trustee under the Indenture, the Form T-1 Statement of Eligibility
          of Wilmington Trust Company to act as trustee under the Trust
          Agreement, and the Form T-1 Statement of Eligibility of Wilmington
          Trust Company to act as trustee under the Guarantee Agreement have
          been duly qualified under the Trust Indenture Act;

               (ix) the Junior Subordinated Debentures are in the form
          contemplated by the Indenture, have been duly authorized, executed and
          delivered by the Company and, when authenticated by the Indenture
          Trustee in the manner provided for in the Indenture and delivered
          against payment therefor, will constitute valid and binding
          obligations of the Company, enforceable against the



                                      -17-
<PAGE>   18

          Company in accordance with their terms, except to the extent that
          enforcement thereof may be limited by bankruptcy, insolvency,
          reorganization or similar laws affecting the rights of creditors
          generally and subject to general principles of equity;

               (x) the Junior Subordinated Debentures are subordinate and junior
          in right of payment to all "Senior and Indebtedness" (as defined in
          the Indenture) of the Company;

               (xi) under current law, the Trust will be classified for United
          States federal income tax purposes as a grantor trust and not as an
          association taxable as a corporation; accordingly, for United States
          federal income tax purposes each beneficial owner of Preferred
          Securities will be treated as owning an undivided beneficial interest
          in the Junior Subordinated Debentures, and stated interest on the
          Junior Subordinated Debentures generally will be included in income by
          a holder of Preferred Securities at the time such interest income is
          paid or accrued in accordance with such holder's regular method of tax
          accounting;

               (xii) to the best of such counsel's knowledge and information
          after due inquiry, (A) the Trust is not required to be authorized to
          do business in any other jurisdiction other than Delaware, except
          where the failure to be so authorized would not have a material
          adverse effect on the Trust's condition (financial or otherwise) or
          results of operations taken as a whole and (B) the Trust is not a
          party to or otherwise bound by any material agreement other than those
          described in the Prospectus;

               (xiii) the Trust Agreement has been duly executed and delivered
          by the Administrative Trustees;

               (xiv) the Company has full corporate power and authority and the
          Trust has full trust power and authority to enter into this Agreement,
          the Indenture, the Trust Agreement, the Guarantee Agreement and the
          Expense Agreement, as applicable, and to issue the Junior Subordinated
          Debentures or the Common Securities and Preferred Securities, as the
          case may be, and to effect the transactions contemplated by this
          Agreement, the Indenture, the Trust Agreement, the Guarantee Agreement
          and the Expense Agreement, as applicable, and each of this Agreement,
          the Indenture, the Trust Agreement, the Guarantee Agreement and the
          Expense Agreement have been duly authorized, executed and delivered by
          the Company and the Trust, as applicable, and constitutes a valid,
          legal and binding obligation of the Company and the Trust, as
          applicable, enforceable in accordance with its terms (except as rights
          to indemnity hereunder may be limited by federal or state securities
          laws and except as such enforceability may be limited by bankruptcy,
          insolvency, reorganization or similar laws affecting the rights of
          creditors generally and subject to general principles of equity). The
          execution, delivery and performance of this Agreement, the Indenture,
          the Trust Agreement, the Guarantee Agreement, the Preferred
          Securities, the Common Securities, the

          Junior Subordinated Debentures and the Expense Agreement and the
          consummation of the transactions herein or therein contemplated will
          not, to the best of such counsel's knowledge, result in a breach or
          violation of any of the terms and provisions of, or constitute a
          default under, any statute, rule or regulation (except that such
          counsel need express no opinion regarding any blue sky or state
          securities laws), any lease, contract, indenture, mortgage, loan
          agreement or other agreement or instrument known to such counsel to
          which the Company, the Trust or any of the Company's subsidiaries is a
          party or by which it is bound or to which any of its property is
          subject, the Company's or any of its subsidiaries' charter or bylaws,
          or the Certificate of Trust or any permit, judgment, order or decree
          known to such counsel of any court or governmental agency or body
          having jurisdiction over the Company, the Trust or any of the
          Company's subsidiaries or any of their respective properties, except
          for any breach, violation or default which would not have a material
          adverse effect on the Company or the Trust; and no consent, approval,
          authorization, order of, designation, declaration or filing by or
          with, any court or any regulatory, administrative or governmental
          agency or body is required for the execution, delivery and performance
          of this Agreement, the Indenture, the Trust Agreement, the Guarantee
          Agreement, the Expense Agreement, the Common Securities, the Preferred
          Securities, or the Junior Subordinated Debentures, or for the
          consummation of the transactions contemplated hereby or thereby (other
          than as may be required by federal or state laws governing banks or
          bank holding companies, the NASD, or by state securities and blue sky
          laws, as to which such counsel need express no opinion), including the
          issuance or sale of the Junior Subordinated Debentures by the Company
          and the Common Securities and Preferred Securities by the Trust,
          except (a) such as may be required under the Act, which have been
          obtained or made, and (b) the qualification of the Trust Agreement,
          the Guarantee Agreement and the Indenture under the Trust Indenture
          Act and the regulations thereunder, all of which have been effected.
          The filing of the Registration Statement and the registration of the
          Junior Subordinated Debentures, the Guarantee and the Preferred
          Securities under the Act does not give rise to any rights for or
          relating to the registration of any shares of capital stock or other
          securities of the Company;

               (xv) neither the Company nor the Trust is, and immediately upon
          completion of the sale of Preferred Securities contemplated hereby,
          neither the Company nor the Trust will be, an "investment company" or
          a company "controlled" by an investment company under the Investment
          Company Act of 1940, as amended; and

               (xvi) to the best of such counsel's knowledge, neither the
          Company nor any of its subsidiaries is in violation of its respective
          charter or bylaws.

               (xvii) the Banks have been duly chartered to conduct the business
          of banking in their state of domicile and the Company has all
          necessary power and authority to own the Banks. The Company and the
          Banks have all necessary consents and approvals under applicable
          federal and state laws and regulations



                                      -19-
<PAGE>   20

          relating to banks and bank holding companies ("banking laws") to own
          their respective assets and carry on their respective businesses as
          currently conducted;

               (xviii) the proceeds from the sale of the Preferred Securities
          will constitute "Tier 1" capital (as defined in 12 C.F.R. Part 325),
          subject to applicable regulatory limitations on the amount thereof
          that can be included in Tier 1 capital.

     In rendering such opinion, such counsel may state that insofar as their
opinion under clause (v) above relates to the accuracy and completeness of the
Prospectus and Registration Statement, including the Incorporated Documents, it
is based upon a general review with the Offerors' representatives and
independent accountants of the information contained therein, without
independent verification by such counsel of the accuracy or completeness of such
information. Such counsel may also rely upon the opinions of other competent
counsel and, as to factual matters, on certificates of officers of the Offerors
and of federal or state agencies or officials, in which case their opinion is to
state that they are so doing and copies of said opinions or certificates are to
be attached to the opinion unless said opinions or certificates (or, in the case
of certificates, the information therein) have been furnished to the
Representative in other form.

          (c) The Underwriters shall have received on the Closing Date the
     opinion of Richards, Layton & Finger, P.A., counsel to Wilmington Trust
     Company, as Property Trustee under the Trust Agreement, Indenture Trustee
     under the Indenture, and Guarantee Trustee under the Guarantee Agreement,
     dated the Closing Date, addressed to the Underwriters, to the effect that:

               (i) Wilmington Trust Company is duly incorporated and is validly
          existing in good standing as a banking corporation under the laws of
          the State of Delaware;

               (ii) Wilmington Trust Company has the power and authority to
          execute, deliver and perform its obligations under the Trust
          Agreement, the Indenture and the Guarantee Agreement;

               (iii) each of the Trust Agreement, the Indenture and the
          Guarantee Agreement has been duly authorized, executed and delivered
          by Wilmington Trust Company and constitutes a legal, valid and binding
          obligation of Wilmington Trust Company, enforceable against Wilmington
          Trust Company, in accordance with its terms;

               (iv) the execution, delivery and performance by Wilmington Trust
          Company of the Trust Agreement, the Indenture and the Guarantee
          Agreement do not conflict with or constitute a breach of the charter
          or bylaws of Wilmington Trust Company; and

               (v) no consent, approval or authorization of, or registration
          with or notice to, any governmental authority or agency of the State
          of Delaware or the United States of America governing the banking or
          trust powers of Wilmington



                                      -20-
<PAGE>   21

          Trust Company is required for the execution, delivery or performance
          by Wilmington Trust Company of the Trust Agreement, the Indenture and
          the Guarantee Agreement.

          (d) The underwriters shall have received on the Closing Date the
     opinion of Richards, Layton & Finger, P.A., as special counsel for the
     Offerors that:

               (i) the Trust has been duly created and is validly existing in
          good standing as a business trust under the Delaware Act, and all
          filings required as of the date hereof under the Delaware Act with
          respect to the creation and valid existence of the Trust as a business
          trust have been made;

               (ii) under the Trust Agreement and the Delaware Act, the Trust
          has the trust power and authority to own property and to conduct its
          business, all as described in the Prospectus;

               (iii) the Trust Agreement constitutes a valid and binding
          obligation of the Company, the Property Trustee and each of the
          Administrative Trustees, and is enforceable against the Company, the
          Property Trustee and each of the Administrative Trustees in accordance
          with its terms;

               (iv) under the Trust Agreement and the Delaware Act, the Trust
          has the trust power and authority (a) to execute and deliver, and to
          perform its obligations under, this Agreement, and (b) to issue, and
          to perform its obligations under, the Preferred Securities and the
          Common Securities;

               (v) under the Trust Agreement and the Delaware Act, the execution
          and delivery by the Trust of this Agreement, and the performance by
          the Trust of its obligations under this Agreement, have been duly
          authorized by all necessary trust action on the part of the Trust;

               (vi) under the Delaware Act, the certificate attached to the
          Trust Agreement as [Exhibit E] is an appropriate form of certificate
          to evidence ownership of the Preferred Securities. The Preferred
          Securities and the Common Securities have been duly authorized by the
          Trust Agreement and are duly and validly issued and, subject to the
          qualifications hereinafter expressed in this paragraph (vi), fully
          paid and non-assessable undivided beneficial interests in the assets
          of the Trust. The respective holders of the Preferred Securities and
          the Common Securities, as beneficial owners of the Trust, will be
          entitled to the same limitation of personal liability extended to
          stockholders of private corporations for profit organized under the
          General Corporation Law of the State of Delaware. Such counsel may
          note that the respective holders of the Preferred Securities and the
          Common Securities may be obligated, pursuant to the Trust Agreement,
          to make certain payments under the Trust Agreement;



                                      -21-
<PAGE>   22

               (vii) under the Trust Agreement and the Delaware Act, the
          issuance of the Preferred Securities and the Common Securities is not
          subject to preemptive or similar rights; and

               (viii) the issuance and sale by the Trust of the Preferred
          Securities and the Common Securities, the purchase by the Trust of the
          Junior Subordinated Debentures, the execution, delivery and
          performance by the Trust of this Agreement and the Guarantee
          Agreement, the consummation by the Trust of the transactions
          contemplated by this Agreement and compliance by the Trust with its
          obligations under this Agreement do not violate (A) any of the
          provisions of the Certificate of Trust or the Trust Agreement or (B)
          any applicable Delaware law or Delaware administrative regulations.

          (e) The Underwriters shall have received from Chapman and Cutler,
     Chicago, Illinois, counsel for the Underwriters, an opinion dated the
     Closing Date, with respect to the formation of the Trust, the validity of
     the Preferred Securities, the Indenture, the Trust Agreement, the Guarantee
     Agreement, the Expense Agreement, this Agreement, the Registration
     Statement, the Prospectus, and other related matters as the Underwriters
     may reasonably request, and such counsel shall have received such papers
     and information as they may reasonably request to enable them to pass upon
     such matters.

          (f) The Underwriters shall have received on the date hereof, and the
     Closing Date a signed letter, dated as of the date hereof, and the Closing
     Date, respectively, in form and substance satisfactory to the Underwriters,
     from Crowe, Chizek and Company to the effect that they are independent
     public accountants with respect to the Trust, the Company and the Company's
     subsidiaries within the meaning of the Act and the related rules and
     regulations and containing statements and information of the type
     ordinarily included in accountants' "comfort letters" to underwriters with
     respect to the financial statements and certain financial information
     contained in the Registration Statement and the Prospectus (and the
     Incorporated Documents).

          (g) Subsequent to the execution and delivery of this Agreement and
     prior to the Closing Date, there shall not have been any change or any
     development involving a reasonably foreseeable change, in or affecting the
     general affairs, management, financial position, shareholders' equity or
     results of operations of the Offerors otherwise than as set forth or
     contemplated in the Prospectus, the effect of which, in your reasonable
     judgment, is material and adverse to the Offerors and makes it
     impracticable or inadvisable to proceed with the public offering or the
     delivery of the Preferred Securities being delivered at the Closing Date,
     on the terms and in the manner contemplated in the Prospectus.

          (h) The Underwriters shall have received on the Closing Date, a
     certificate or certificates of the chief executive officer and the
     principal financial officer of the Company, to the effect that, as of the
     Closing Date each of them severally represents as follows:

               (i) The Prospectus was filed with the Commission pursuant to Rule
          424(b) within the applicable period prescribed for such filing by the
          rules and



                                      -22-
<PAGE>   23

          regulations under the Act and in accordance with Section 4 of this
          Agreement; no stop order suspending the effectiveness of the
          Registration Statement has been issued, and no proceedings for such
          purpose have been initiated or are, to his knowledge, threatened by
          the Commission.

               (ii) The representations and warranties of the Company set forth
          in Section 1 of this Agreement are true and correct at and as of the
          Closing Date, and the Company has performed all of its obligations
          under this Agreement to be performed at or prior to the Closing Date.

          (i) The Underwriters shall have received on the Closing Date a
     certificate or certificates of the Administrative Trustees, to the effect
     that, as of the Closing Date each of them severally represents as follows:

               (i) The Prospectus was filed with the Commission pursuant to Rule
          424(b) within the applicable period prescribed for such filing by the
          rules and regulations under the Act and in accordance with Section 4
          of this Agreement; no stop order suspending the effectiveness of the
          Registration Statement has been issued, and no proceedings for such
          purpose have been initiated or are, to his knowledge, threatened by
          the Commission.

               (ii) The representations and warranties of the Trust set forth in
          Section 1 of this Agreement are true and correct at and as of the
          Closing Date and the Trust has performed all of its obligations under
          this Agreement to be performed at or prior to the Closing Date.

          (j) The Offerors shall have furnished to the Underwriters such further
     certificates and documents as the Underwriters may reasonably have
     requested, including with respect to (i) the treatment of the Junior
     Subordinated Debentures as indebtedness of the Company and (ii) the
     deductibility of the interest on the Junior Subordinated Debenture.

     The opinions and certificates mentioned in this Agreement shall be deemed
to be in compliance with the provisions hereof only if they are in all material
respects reasonably satisfactory to the Underwriters and to Chapman and Cutler,
counsel for the Underwriters.

     If any of the conditions hereinabove provided for in this Section 6 shall
not have been fulfilled when and as required by this Agreement to be fulfilled,
the obligations of the Underwriters hereunder may be terminated by the
Underwriters by notifying the Company and the Trust of such termination in
writing or by telegram at or prior to the Closing Date. In such event, the
Offerors and the Underwriters shall not be under any obligation to each other
(except to the extent provided in Sections 5 and 7 hereof).

     Section 7. Indemnification. (a) The Offerors jointly and severally agree to
indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of the Act or the Exchange Act
against any losses, claims, damages or liabilities, joint



                                      -23-
<PAGE>   24

or several, to which such Underwriter or such controlling person may become
subject under the Act, the Exchange Act or other federal or state statutory law
or regulation, at common law or otherwise (including in settlement of any
litigation if such settlement is effected with the written consent of the
Offerors), insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in the Registration Statement,
including the information deemed to be part of the Registration Statement at the
time of effectiveness pursuant to Rule 430A and/or Rule 434, if applicable, any
preliminary prospectus, the Prospectus, the Incorporated Documents or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading; and will
reimburse each Underwriter and each such controlling person for any legal or
other expenses reasonably incurred by such Underwriter or such controlling
person in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the Offerors will not be
liable in any such case to the extent that (i) any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in the Registration Statement,
any preliminary prospectus, the Prospectus, the Incorporated Documents or any
amendment or supplement thereto in reliance upon and in conformity with written
information furnished to the Offerors by or on behalf of any Underwriter through
the Representative, specifically for use therein; or (ii) if such statement or
omission was contained or made in any preliminary prospectus and corrected in
the Prospectus and (1) any such loss, claim, damage or liability suffered or
incurred by any Underwriter (or any person who controls any Underwriter)
resulted from an action, claim or suit by any person who purchased Preferred
Securities which are the subject thereof from such Underwriter in the offering
and (2) such Underwriter failed to deliver or provide a copy of the Prospectus
to such person at or prior to the confirmation of the sale of such Preferred
Securities in any case where such delivery is required by the Act. In addition
to its other obligations under this Section 10(a), the Offerors agree that, as
an interim measure during the pendency of any claim, action, investigation,
inquiry or other proceeding arising out of or based upon any statement or
omission, or any alleged statement or omission, described in this Section 10(a),
it will reimburse the Underwriters on a quarterly basis for all reasonable legal
and other expenses incurred in connection with investigating or defending any
such claim, action, investigation, inquiry or other proceeding, notwithstanding
the absence of a judicial determination as to the propriety and enforceability
of the Offerors' obligation to reimburse the Underwriters for such expenses and
the possibility that such payments might later be held to have been improper by
a court of competent jurisdiction. To the extent that any such interim
reimbursement payment is held by a court of competent jurisdiction to have been
improper, each recipient thereof will promptly return it to the Offerors. This
indemnity agreement will be in addition to any liability which the Offerors may
otherwise have.

     (b) Each Underwriter will severally indemnify and hold harmless the
Offerors, the trustees, and its directors, each of its officers who signed the
Registration Statement and each person, if any, who controls the Offerors within
the meaning of the Act or the Exchange Act, against any losses, claims, damages
or liabilities to which the Offerors, or any such director, officer or
controlling person may become subject under the Act, the Exchange Act or other
federal or state statutory law or regulation, at common law or otherwise
(including in settlement of any litigation, if such settlement is effected with
the written consent of such Underwriter),



                                      -24-
<PAGE>   25

insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue or alleged untrue statement
of any material fact contained in the Registration Statement, any preliminary
prospectus, the Prospectus, or any amendment or supplement thereto, or arise out
of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in the Registration Statement, any preliminary prospectus, the
Prospectus, or any amendment or supplement thereto in reliance upon any written
information furnished to the Offerors by such Underwriter through the
Representative specifically for use in the preparation thereof; and will
reimburse any legal or other expenses reasonably incurred by the Offerors, or
any such director, officer or controlling person in connection with
investigating or defending any such loss, claim, damage, liability or action.
This indemnity agreement will be in addition to any liability which such
Underwriter may otherwise have.

     (c) The Company agrees to indemnify the Trust against all loss, liability,
claim damage and expense whatsoever, which may become due from the Trust under
paragraph (a).

     (d) Promptly after receipt by an indemnified party under this Section of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against an indemnifying party under this
Section, notify the indemnifying party of the commencement thereof; but the
omission so to notify the indemnifying party will not relieve it from any
liability which it may have to any indemnified party except to the extent that
the indemnifying party was prejudiced by such failure to notify. In case any
such action is brought against any indemnified party, and it notifies an
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate in, and, to the extent that it may wish, jointly with
all other indemnifying parties similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party; provided, however,
if the defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, or the indemnified and indemnifying parties may have
conflicting interests which would make it inappropriate for the same counsel to
represent both of them, the indemnified party or parties shall have the right to
select separate counsel to assume such legal defense and otherwise to
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of its election so to assume the defense of such action and approval by
the indemnified party of counsel, the indemnifying party will not be liable to
such indemnified party under this Section for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless (i) the indemnified party shall have employed such counsel in
connection with the assumption of legal defense in accordance with the proviso
to the next preceding sentence (it being understood, however, that the
indemnifying party shall not be liable for the expenses of more than one
separate counsel, approved by the Representative in the case of paragraph (a)
representing all indemnified parties not having different or additional defenses
or potential conflicting interests among themselves who are parties to such
action), (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a


                                      -25-
<PAGE>   26

reasonable time after notice of commencement of the action or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party. No indemnifying party shall,
without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability arising out
of such proceeding.

     (e) If the indemnification provided for in this Section is unavailable to
an indemnified party under paragraphs (a) or (b) hereof in respect of any
losses, claims, damages or liabilities referred to therein, then each applicable
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Offerors and the
Underwriters from the offering of the Preferred Securities or (ii) if the
allocation provided by clause (i) above is not permitted by applicable law, in
such proportion as is appropriate to reflect not only the relative benefits
referred to in clause (i) above but also the relative fault of the Offerors and
the Underwriters in connection with the statements or omissions which resulted
in such losses, claims, damages or liabilities, as well as any other relevant
equitable considerations. The respective relative benefits received by the
Offerors and the Underwriters shall be deemed to be in the same proportion in
the case of the Offerors as the total price paid to the Offerors for the
Preferred Securities by the Underwriters (net of underwriting discount but
before deducting expenses), and in the case of the Underwriters as the
underwriting discount received by them bears to the total of such amounts paid
to the Offerors and received by the Underwriters as underwriting discount in
each case as contemplated by the Prospectus. The relative fault of the Offerors
and the Underwriters shall be determined 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 Offerors or by the Underwriters and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The amount paid or payable by a party as a result of
the losses, claims, damages and liabilities referred to above shall be deemed to
include any legal or other fees or expenses reasonably incurred by such party in
connection with investigating or defending any action or claim.

     The Offerors and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section, no Underwriter shall be required
to contribute any amount in excess of the amount by which the total price at
which the Preferred Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission. No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations to contribute
pursuant to this Section are several in proportion to their respective
underwriting commitments and not joint.




                                      -26-
<PAGE>   27

     (f) The provisions of this Section shall survive any termination of the
     Agreement.

     Section 8. Default of Underwriters. It shall be a condition to the
agreement and obligation of the Offerors to sell and deliver the Preferred
Securities hereunder, and of each Underwriter to purchase the Preferred
Securities hereunder, that, except as hereinafter in this paragraph provided,
each of the Underwriters shall purchase and pay for all Preferred Securities
agreed to be purchased by such Underwriter hereunder upon tender to the
Representative of all such Preferred Securities in accordance with the terms
hereof. If any Underwriter or Underwriters default in their obligations to
purchase Preferred Securities hereunder on the Closing Date and the aggregate
number of Preferred Securities which such defaulting Underwriter or Underwriters
agreed but failed to purchase does not exceed 10 percent of the total number of
Preferred Securities which the Underwriters are obligated to purchase on the
Closing Date, the Representative may make arrangements satisfactory to the
Offerors for the purchase of such Preferred Securities by other persons,
including any of the Underwriters, but if no such arrangements are made by such
date the nondefaulting Underwriters shall be obligated severally, in proportion
to their respective commitments hereunder, to purchase the Preferred Securities
which such defaulting Underwriters agreed but failed to purchase on such date.
If any Underwriter or Underwriters so default and the aggregate number of
Preferred Securities with respect to which such default or defaults occur is
more than the above percentage and arrangements satisfactory to the
Representative and the Offerors for the purchase of such Preferred Securities by
other persons are not made within 36 hours after such default, this Agreement
will terminate without liability on the part of any nondefaulting Underwriter or
the Offerors, except for the expenses to be paid by the Offerors pursuant to
Section 5 hereof and except to the extent provided in Section 7 hereof.

     In the event that Preferred Securities to which a default relates are to be
purchased by the nondefaulting Underwriters or by another party or parties, the
Representative or the Offerors shall have the right to postpone the Closing Date
for not more than seven business days in order that the necessary changes in the
Registration Statement, Prospectus and any other documents, as well as any other
arrangements, may be effected. As used in this Agreement, the term "Underwriter"
includes any person substituted for an Underwriter under this Section. Nothing
herein will relieve a defaulting Underwriter from liability for its default.

     Section 9. Termination. Without limiting the right to terminate this
Agreement pursuant to any other provision hereof, this Agreement may be
terminated by you prior to the Closing Date, if (i) trading in securities on the
New York Stock Exchange shall have been suspended or minimum prices shall have
been established on such exchange, or (ii) a banking moratorium shall have been
declared by Illinois, New York, or United States authorities, or (iii) there
shall have been any material adverse change in financial markets or in
political, economic or financial conditions from the date hereof which, in the
opinion of the Representative, either renders it impracticable or inadvisable to
proceed with the offering and sale of the Preferred Securities on the terms set
forth in the Prospectus or materially and adversely affects the market for the
Preferred Securities, or (iv) there shall have been an outbreak of major armed
hostilities between the United States and any foreign power which in the
reasonable opinion of the Representative makes it impractical or inadvisable to

succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day (and without any reduction of interest or any other
payment in respect of any such acceleration), in each case with the same force
and effect as if made on such date (each date on which distributions are payable
in accordance with this Section 401(a), a "Distribution Date").

     (b) The Trust Securities represent undivided beneficial interests in the

     (c) Distributions on the Trust Securities shall be made by the Property

shall be the 15th day of March, June, September or December for Distributions
payable on the last calendar day of the respective month; provided, however,
that for any Trust Securities held in global form, Distributions shall be

     SECTION 402. REDEMPTION.

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

     (b) Notice of redemption shall be given by the Property Trustee by
first-class mail, postage prepaid, mailed not less than 30 nor more than 60 days
prior to the Redemption Date to each Holder of Trust Securities to be redeemed,
at such Holder's address appearing in the Securities Register. The Property
Trustee shall have no responsibility for the accuracy of any CUSIP number
contained in such notice. All notices of redemption shall state:

          (i)   the Redemption Date;

          (ii)  the Redemption Price;

          (iii) the CUSIP number;

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

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

          (vi)  the place or places at which Trust Securities are to be

                                       17

<PAGE>   25


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

     (d) If the Property Trustee gives a notice of redemption in respect of any
Preferred Securities, then, by 12:00 noon, New York City time, on the Redemption
Date, subject to Section 402(c), the Property Trustee, subject to Section
402(c), shall, with respect to Preferred Securities held in global form, deposit
with the Clearing Agency for such Preferred Securities, to the extent available
therefor, funds sufficient to pay the applicable Redemption Price and will give
such Clearing Agency irrevocable instructions and authority to pay the
Redemption Price to the Holders of the Preferred Securities. With respect to
Trust Securities that are not held in global form, the Property Trustee, subject
to Section 402(c), shall deposit with the Paying Agent funds sufficient to pay
the applicable Redemption Price and shall give the Paying Agent irrevocable
instructions and authority to pay the Redemption Price to the record holders
thereof upon surrender of their Preferred Securities Certificates.
Notwithstanding the foregoing, Distributions payable on or prior to the
Redemption Date for any Trust Securities called for redemption shall be payable
to the Holders of such Trust Securities as they appear on the Register for the
Trust Securities on the relevant record dates for the related Distribution
Dates. If notice of redemption shall have been given and funds deposited as
required, then upon the date of such deposit, (i) all rights of Securityholders
holding Trust Securities so called for redemption shall cease, except the right
of such Securityholders to receive the Redemption Price, (ii) such Securities
shall cease to be Outstanding, (iii) the Clearing Agency for the Preferred
Securities or its nominee, as the registered Holder of the Global Preferred
Securities Certificate, shall receive a registered global certificate or
certificates representing the Debentures to be delivered upon such distribution
with respect to Preferred Securities held by the Clearing Agency or its nominee,
and (iv) any Trust Securities Certificates not held by the Clearing Agency for
the Preferred Securities or its nominee as specified in clause (iii) above will
be deemed to represent Debentures having a principal amount equal to the stated
Liquidation Amount of the Trust Securities represented thereby 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 Securities Registrar for transfer or reissuance. In the event that any date
on which any Redemption Price is payable is not a Business Day, then payment of
the Redemption Price payable on such date shall be made on the next succeeding
day that is a Business Day (and without any interest or other payment in respect
of any such delay) except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day (and without any reduction of interest or any other payment in respect of
any such acceleration), in each case with the same force and effect as if made
on such date. In the event that payment of the Redemption Price in respect of
any Trust Securities called for redemption is improperly withheld or refused and
not paid either by the Trust or by the Depositor pursuant to the Guarantee,
Distributions on such Trust Securities shall continue to accumulate, at the then
applicable rate, from the Redemption Date originally established by the Trust
for such Trust Securities to the date such Redemption Price is actually paid, in
which case the actual payment date shall be the date fixed for redemption for
purposes of calculating the Redemption Price.


                                       18

     (e) Payment of the Redemption Price on the Trust Securities shall be made
to the record holders thereof as they appear on the Securities Register for the
Trust Securities on the relevant record date, which shall be the date 15 days
prior to the relevant Redemption Date.

     (f) Subject to Section 403(a), if less than all the Outstanding Trust
Securities are to be redeemed on a Redemption Date, then the aggregate
Liquidation Amount of Trust Securities to be redeemed shall be allocated on a
pro rata basis (based on Liquidation Amounts) among the Common Securities and
the Preferred Securities. The particular Preferred Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the
Property Trustee from the Outstanding Preferred Securities not previously called
for redemption, by such method (including, without limitation, by lot) as the
Property Trustee shall deem fair and appropriate and which may provide for the
selection for redemption of portions (equal to $25 or an integral multiple of
$25 in excess thereof) of the Liquidation Amount of Preferred Securities of a
denomination larger than $25; provided, however, in the event the redemption
relates only to Preferred Securities purchased and held by the Depositor that
are being redeemed prior to _________, 2005, in exchange for a Like Amount of
Debentures, the Property Trustee shall select those particular Preferred
Securities for redemption. The Property Trustee shall promptly notify the
Securities Registrar in writing of the Preferred Securities selected for
redemption and, in the case of any Preferred Securities selected for partial
redemption, the Liquidation Amount thereof to be redeemed. For all purposes of
this Trust Agreement, unless the context otherwise requires, all provisions
relating to the redemption of Preferred Securities shall relate, in the case of
any Preferred Securities redeemed or to be redeemed only in part, to the portion
of the Liquidation Amount of Preferred Securities which has been or is to be
redeemed.

     SECTION 403. SUBORDINATION OF COMMON SECURITIES.

     (a) Payment of Distributions (including Additional Amounts, if applicable)
on, and the Redemption Price of, the Trust Securities, as applicable, shall be
made, subject to Section 402(f), pro rata among the Common Securities and the
Preferred Securities based on the Liquidation Amount of the Trust Securities;
provided, however, that if on any Distribution Date or Redemption Date any Event
of Default resulting from a Debenture Event of Default shall have occurred and
be continuing, no payment of any Distribution (including Additional Amounts, if
applicable) on, or Redemption Price of, any Common Security, and no other
payment on account of the redemption, liquidation or other acquisition of Common
Securities, shall be made unless payment in full in cash of all accumulated and
unpaid Distributions (including Additional Amounts, if applicable) on all
Outstanding Preferred Securities for all Distribution periods terminating on or
prior thereto, or in the case of payment of the Redemption Price the full amount
of such Redemption Price on all Outstanding Preferred Securities then called for
redemption, shall have been made or provided for, and all funds immediately
available to the Property Trustee shall first be applied to the payment in full
in cash of all Distributions (including Additional Amounts, if applicable) on,
or the Redemption Price of, Preferred Securities then due and payable.

     (b) In the case of the occurrence of any Event of Default resulting from a
Debenture Event of Default, the record holder of Common Securities, the
Depositor, shall be deemed to have waived any right to act with respect to any
such Event of Default under this Trust Agreement until the effect of all such
Events of Default with respect to the Preferred Securities shall have been
cured,

                                       19

waived or otherwise eliminated. Until any such Event of Default under this Trust
Agreement with respect to the Preferred Securities shall have been so cured,
waived or otherwise eliminated, the Property Trustee shall act solely on behalf
of the record holders of the Preferred Securities and not the record holder of
the Common Securities, and only the Holders of the Preferred Securities shall
have the right to direct the Property Trustee to act on their behalf.

     SECTION 404. PAYMENT PROCEDURES.

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

     SECTION 405. TAX RETURNS AND REPORTS.

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

     SECTION 406. PAYMENT OF TAXES, DUTIES, ETC. OF THE TRUST.

     Upon receipt under the Debentures of Additional Interest (as defined in
Section 1.1 of the Indenture), the Property Trustee, at the direction of an
Administrative Trustee or the Depositor, shall promptly pay any taxes, duties or
governmental charges of whatsoever nature (other than withholding taxes) imposed
on the Trust by the United States or any other taxing authority.

     SECTION 407. PAYMENTS UNDER INDENTURE.

     Any amount payable hereunder to any record holder of Preferred Securities
shall be reduced by the amount of any corresponding payment such Holder has
directly received under the Indenture pursuant to Section 513(b) or (c) hereof.

                          TRUST SECURITIES CERTIFICATES

     SECTION 501. INITIAL OWNERSHIP.

     Upon the creation of the Trust and the contribution by the Depositor
pursuant to Section 203 and until the issuance of the Trust Securities, and at
any time during which no Trust Securities are outstanding, the Depositor shall
be the sole beneficial owner of the Trust.

     SECTION 502. THE TRUST SECURITIES CERTIFICATES.

     The Preferred Securities Certificates shall be issued in minimum
denominations of $25 Liquidation Amount and integral multiples of $25 in excess
thereof, and the Common Securities Certificates shall be issued in denominations
of $25 Liquidation Amount and multiples thereof (which may, in the case of the
Common Securities, include fractional amounts). The Trust Securities
Certificates shall be executed on behalf of the Trust by manual or facsimile
signature of at least one Administrative Trustee. Trust Securities Certificates
bearing the manual or facsimile signatures of individuals who were, at the time
when such signatures shall have been affixed, authorized to sign on behalf of
the Trust, shall be validly issued and entitled to the benefits of this Trust
Agreement, notwithstanding that such individuals or any of them shall have
ceased to be so authorized prior to the delivery of such Trust Securities
Certificates or did not hold such offices at the date of delivery of such Trust
Securities Certificates. A transferee of a Trust Securities Certificate shall
become a Securityholder, and shall be entitled to the rights and subject to the
obligations of a Securityholder hereunder, upon due registration of such Trust
Securities Certificate in such transferee's name pursuant to Sections 504, 511
and 513.

     SECTION 503. EXECUTION, AUTHENTICATION AND DELIVERY OF TRUST SECURITIES
CERTIFICATES.

     (a) On the Closing Date, the Administrative Trustees shall cause Trust
Securities Certificates, in an aggregate Liquidation Amount as provided in
Sections 204 and 205, to be executed on behalf of the Trust by at least one of
the Administrative Trustees and delivered to or upon the written order of the
Depositor, signed by its Chief Executive Officer, President, any Vice President
or its Treasurer without further corporate action by the Depositor, in
authorized denominations.

     (b) A Preferred Securities Certificate shall not be valid until
authenticated by the manual signature of an authorized signatory of the Property
Trustee in substantially the form of Exhibit E attached hereto. The signature
shall be conclusive evidence that the Preferred Securities Certificate has been
authenticated under this Trust Agreement. Each Preferred Security Certificate
shall be dated the date of its authentication.

     Upon the written order of the Trust signed by one of the Administrative
Trustees, the Property Trustee shall authenticate and make available for
delivery the Preferred Securities Certificates.


                                       21

<PAGE>   29



     The Property Trustee may appoint an Authenticating Agent acceptable to the
Trust to authenticate the Preferred Securities. An Authenticating Agent may
authenticate the Preferred Securities whenever the Property Trustee may do so.
Each reference in this Trust Agreement 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 Company or the Trust.

     SECTION 503A. GLOBAL PREFERRED SECURITY.

     (a) Any Global Preferred Security issued under this Trust Agreement shall
be registered in the name of the nominee of the Clearing Agency and delivered to
such custodian therefor, and such Global Preferred Security shall constitute a
single Preferred Security for all purposes of this Trust Agreement.

     (b) Notwithstanding any other provision in this Trust Agreement, no Global
Preferred Security may be exchanged for Preferred Securities registered in the
names of persons other than the Depositary or its nominee unless (i) the
Depositary notifies the Debenture Trustee that it is unwilling or unable to
continue as a depositary for such Global Preferred Securities and the Depositor
is unable to locate a qualified successor depositary, (ii) the Depositor
executes and delivers to the Debenture Trustee a written order stating that it
elects to terminate the book-entry system through the Depositary or (iii) there
shall have occurred and be continuing a Debenture Event of Default.

     (c) If a Preferred Security is to be exchanged in whole or in part for a
beneficial interest in a Global Preferred Security, then either (i) such Global
Preferred Security shall be so surrendered for exchange or cancellation as
provided in this Article V or (ii) the Liquidation amount thereof shall be
reduced or increased by an amount equal to the portion thereof to be so
exchanged or cancelled, or equal to the Liquidation Amount of such other
Preferred Securities to be so exchanged for a beneficial interest therein, as
the case may be, by means of an appropriate adjustment made on the records of
the Securities Registrar, whereupon the Property Trustee, in accordance with the
rules and procedures of the Depositary for such Global Preferred Security (the
"Applicable Procedures"), shall instruct the Clearing Agency or its authorized
representative to make a corresponding adjustment to its records. Upon any such
surrender or adjustment of a Global Preferred Security by the Clearing Agency,
accompanied by registration instructions, the Administrative Trustees shall
execute and the Property Trustee shall, subject to Section 504(b) and as
otherwise provided in this Article V, authenticate and deliver any Preferred
Securities issuable in exchange for such Global Preferred Security (or any
portion thereof) in accordance with the instructions of the Clearing Agency. The
Property Trustee shall not be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be fully protected in
relying on, such instructions.

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


                                       22

<PAGE>   30


     (e) The Clearing Agency or its nominee, as the registered owner of a Global
Preferred Security, shall be considered the Holder of the Preferred Securities
represented by such Global Preferred Security for all purposes under this Trust
Agreement and the Preferred Securities, and owners of beneficial interests in
such Global Preferred Security shall hold such interests pursuant to the
Applicable Procedures and, except as otherwise provided herein, shall not be
entitled to receive physical delivery of any such Preferred Securities in
definitive form and shall not be considered the Holders thereof under this Trust
Agreement. Accordingly, any such owner's beneficial interest in the Global
Preferred Securities shall be shown only on, and the transfer of such interest
shall be effected only through, records maintained by the Clearing Agency or its
nominee. Neither the Property Trustee, the Securities Registrar nor Depositor
shall have any liability in respect of any transfers effected by the Clearing
Agency.

     (f) The rights of owners of beneficial interests in a Global Preferred
Security shall be exercised only through the Clearing Agency and shall be
limited to those established by law and agreements between such owners and the
Clearing Agency.

     SECTION 504. REGISTRATION OF TRANSFER AND EXCHANGE OF PREFERRED SECURITIES
CERTIFICATES.

     (a) The Depositor shall keep or cause to be kept, at the office or agency
maintained pursuant to Section 508, a register or registers for the purpose of
registering Trust Securities Certificates and, subject to the provisions of
Section 503A, transfers and exchanges of Preferred Securities Certificates
(herein referred to as the "Securities Register") in which the registrar
designated by the Depositor (the "Securities Registrar"), subject to such
reasonable regulations as it may prescribe, shall provide for the registration
of Preferred Securities Certificates and Common Securities Certificates (subject
to Section 510 in the case of the Common Securities Certificates) and
registration of transfers and exchanges of Preferred Securities Certificates as
herein provided. The Property Trustee shall be the initial Securities Registrar.

     (b) Subject to the provisions of Section 503A, upon surrender for
registration of transfer of any Preferred Securities Certificate at the office
or agency maintained pursuant to Section 508, the Administrative Trustees or any
one of them shall execute and deliver, in the name of the designated transferee
or transferees, one or more new Preferred Securities Certificates in authorized
denominations of a like aggregate Liquidation Amount dated the date of execution
by such Administrative Trustee or Trustees. The Securities Registrar shall not
be required to register the transfer of any Preferred Securities that have been
called for redemption. At the option of a record holder, Preferred Securities
Certificates may be exchanged for other Preferred Securities Certificates in
authorized denominations of the same class and of a like aggregate Liquidation
Amount upon surrender of the Preferred Securities Certificates to be exchanged
at the office or agency maintained pursuant to Section 508.

     (c) Every Preferred Securities Certificate presented or surrendered for
registration of transfer or exchange, subject to the provisions of Section 503A,
shall be accompanied by a written instrument of transfer in form satisfactory to
the Property Trustee and the Securities Registrar duly

                                       23

<PAGE>   31


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

     (d) No service charge shall be made for any registration of transfer or
exchange of Preferred Securities Certificates, subject to the provisions of
Section 503A, but the Securities Registrar may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer or exchange of Preferred Securities Certificates.

     (e) Preferred Securities may only be transferred, in whole or in part, in
accordance with the terms and conditions set forth in this Trust Agreement. Any
transfer or purported transfer of any Preferred Security not made in accordance
with this Trust Agreement shall be null and void. A Preferred Security that is
not a Global Preferred Security may be transferred, in whole or in part, to a
Person who takes delivery in the form of another Preferred Security that is not
a Global Preferred Security as provided in Section 504(a). A beneficial interest
in a Global Preferred Security may be exchanged for a Preferred Security that is
not a Global Preferred Security only as provided in Section 503A.

     SECTION 505. MUTILATED, DESTROYED, LOST OR STOLEN TRUST SECURITIES
CERTIFICATES.

     If (a) any mutilated Trust Securities certificate shall be surrendered to
the Securities Registrar, or if the Securities Registrar shall receive evidence
to its satisfaction of the destruction, loss or theft of any Trust Securities
Certificate; and (b) there shall be delivered to the Securities Registrar and
the Administrative Trustees such security or indemnity as may be required by
them to save each of them harmless, then in the absence of notice that such
Trust Securities Certificate shall have been acquired by a bona fide purchaser,
the Administrative Trustees, or any one of them, on behalf of the Trust shall
execute and make available for delivery, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Trust Securities Certificate, a new Trust
Securities Certificate of like class, tenor and denomination. In connection with
the issuance of any new Trust Securities Certificate under this Section 505, the
Administrative Trustees or the Securities Registrar may require the payment of a
sum sufficient to cover any tax or other governmental charge that may be imposed
in connection therewith. Any duplicate Trust Securities Certificate issued
pursuant to this Section 505 shall constitute conclusive evidence of an
undivided beneficial interest in the assets of the Trust, as if originally
issued, whether or not the lost, stolen or destroyed Trust Securities
Certificate shall be found at any time.

     SECTION 506. PERSONS DEEMED SECURITYHOLDERS.


                                       24

<PAGE>   32



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

     SECTION 507. ACCESS TO LIST OF SECURITYHOLDERS' NAMES AND ADDRESSES.

     At any time when the Property Trustee is not also acting as the Securities
Registrar, the Administrative Trustees or the Depositor shall furnish or cause
to be furnished to the Property Trustee (a) within five Business Days of March
15, June 15, September 15 and December 15 of each year, a list, in such form as
the Property Trustee may reasonably require, of the names and addresses of the
Securityholders as of the most recent record date; and (b) promptly after
receipt by any Administrative Trustee or the Depositor of a request therefor
from the Property Trustee in order to enable the Property Trustee to discharge
its obligations under this Trust Agreement, in each case to the extent such
information is in the possession or control of the Administrative Trustees or
the Depositor and is not identical to a previously supplied list or has not
otherwise been received by the Property Trustee in its capacity as Securities
Registrar. The rights of Securityholders to communicate with other
Securityholders with respect to their rights under this Trust Agreement or under
the Trust Securities, and the corresponding rights of the Trustee shall be as
provided in the Trust Indenture Act. Each Holder, by receiving and holding a
Trust Securities Certificate, and each owner shall be deemed to have agreed not
to hold the Depositor, the Property Trustee or the Administrative Trustees
accountable by reason of the disclosure of its name and address, regardless of
the source from which such information was derived.

     SECTION 508. MAINTENANCE OF OFFICE OR AGENCY.

     The Administrative Trustees shall maintain, or cause to be maintained, in
The City of New York, or other location designated by the Administrative
Trustees, an office or offices or agency or agencies where Preferred Securities
Certificates may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Trustees in respect of the Trust
Securities Certificates may be served. The Administrative Trustees initially
designate the Corporate Trust Office of the Property Trustee, Wilmington Trust
Company, as the principal corporate trust office for such purposes. The
Administrative Trustees shall give prompt written notice to the Depositor and to
the Securityholders of any change in the location of the Securities Register or
any such office or agency.

     SECTION 509. APPOINTMENT OF PAYING AGENT.

     The Paying Agent shall make Distributions to Securityholders from the
Payment Account and shall report the amounts of such Distributions to the
Property Trustee and the Administrative Trustees. Any Paying Agent shall have
the revocable power to withdraw funds from the Payment Account for the purpose
of making the Distributions referred to above. The Administrative Trustees may
revoke such power and remove the Paying Agent if such Trustees determine in
their sole discretion that the Paying Agent shall have failed to perform its
obligations under this Trust

                                       25

<PAGE>   33



Agreement in any material respect. The Paying Agent shall initially be the
Property Trustee, and any co-paying agent chosen by the Property Trustee, and
acceptable to the Administrative Trustees and the Depositor. Any Person acting
as Paying Agent shall be permitted to resign as Paying Agent upon 30 days'
written notice to the Administrative Trustees, the Property Trustee and the
Depositor. In the event that the Property Trustee shall no longer be the Paying
Agent or a successor Paying Agent shall resign or its authority to act be
revoked, the Administrative Trustees shall appoint a successor that is
acceptable to the Property Trustee and the Depositor to act as Paying Agent
(which shall be a bank or trust company). The Administrative Trustees shall
cause such successor Paying Agent or any additional Paying Agent appointed by
the Administrative Trustees to execute and deliver to the Trustees an instrument
in which such successor Paying Agent or additional Paying Agent shall agree with
the Trustees that as Paying Agent, such successor Paying Agent or additional
Paying Agent shall hold all sums, if any, held by it for payment to the
Securityholders in trust for the benefit of the Securityholders entitled thereto
until such sums shall be paid to such Securityholders. The Paying Agent shall
return all unclaimed funds to the Property Trustee and, upon removal of a Paying
Agent, such Paying Agent shall also return all funds in its possession to the
Property Trustee. The provisions of Sections 801, 803 and 806 shall apply to the
Property Trustee also in its role as Paying Agent, for so long as the Property
Trustee shall act as Paying Agent and, to the extent applicable, to any other
paying agent appointed hereunder. Any reference in this Agreement to the Paying
Agent shall include any co-paying agent unless the context requires otherwise.

     SECTION 510. OWNERSHIP OF COMMON SECURITIES BY DEPOSITOR.

     On the Closing Date, the Depositor shall acquire and retain beneficial and
record ownership of the Common Securities. To the fullest extent permitted by
law, any attempted transfer of the Common Securities (other than a transfer in
connection with a merger or consolidation of the Depositor into another
corporation pursuant to Section 12.1 of the Indenture) shall be void. The
Administrative Trustees shall cause each Common Securities Certificate issued to
the Depositor to contain a legend stating "THIS CERTIFICATE IS NOT
TRANSFERABLE."

     SECTION 511. TRUST SECURITIES CERTIFICATES.

     (a) Upon their original issuance, Preferred Securities Certificates shall
be issued in the form of one or more fully registered Global Preferred
Securities Certificates which will be deposited with or on behalf of the
Clearing Agency and registered in the name of the Clearing Agency's nominee.
Unless and until it is exchangeable in whole or in part for the Preferred
Securities in definitive form, a global security may not be transferred except
as a whole by the Clearing Agency to a nominee of the Clearing Agency or by a
nominee of the Clearing Agency to the Clearing Agency or another nominee of the
Clearing Agency or by the Clearing Agency or any such nominee to a successor of
such Clearing Agency or a nominee of such successor.

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

     SECTION 512. NOTICES TO CLEARING AGENCY.


                                       26

<PAGE>   34
     To the extent that a notice or other communication to the Holders is
required under this Trust Agreement, for so long as Preferred Securities are
represented by a Global Preferred Securities Certificate, the Trustees shall
give all such notices and communications specified herein to be given to the
Clearing Agency, and shall have no obligations to provide notice to the owners
of the beneficial interest in the Global Preferred Securities.

     SECTION 513. RIGHTS OF SECURITYHOLDERS.

     (a) The legal title to the Trust Property is vested exclusively in the
Property Trustee (in its capacity as such) in accordance with Section 209, and
the Securityholders shall not have any right or title therein other than the
undivided beneficial interest in the assets of the Trust conferred by their
Trust Securities and they shall have no right to call for any partition or
division of property, profits or rights of the Trust except as described below.
The Trust Securities shall be personal property giving only the rights
specifically set forth therein and in this Trust Agreement. The Trust Securities
shall have no preemptive or similar rights. When issued and delivered to Holders
of the Preferred Securities against payment of the purchase price therefor, the
Preferred Securities shall be fully paid and nonassessable interests in the
Trust. The Holders of the Preferred Securities, in their capacities as such,
shall be entitled to the same limitation of personal liability extended to
stockholders of private corporations for profit organized under the General
Corporation Law of the State of Delaware.

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

     (c) For so long as any Preferred Securities remain outstanding, upon a
Debenture Event of Default arising from the failure to pay interest or principal
on the Debentures, the Holders of any Preferred Securities then Outstanding
shall, to the fullest extent permitted by law, have the right to directly
institute proceedings for enforcement of payment to such Holders of principal of
or interest on the Debentures having a principal amount equal to the Liquidation
Amount of the Preferred Securities of such Holders.

                                       27

<PAGE>   35



     (a) Except as provided in this Section 601, in Sections 512, 810 and 1002
and in the Indenture and as otherwise required by law, no record Holder of
Preferred Securities shall have any right to vote or in any manner otherwise
control the administration, operation and management of the Trust or the
obligations of the parties hereto, nor shall anything herein set forth, or
contained in the terms of the Trust Securities Certificates, be construed so as
to constitute the Securityholders from time to time as partners or members of an
association.

     (b) So long as any Debentures are held by the Property Trustee on behalf of
the Trust, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
executing any trust or power conferred on the Debenture Trustee with respect to
such Debentures; (ii) waive any past default which is waivable under Article VII
of the Indenture; (iii) exercise any right to rescind or annul a declaration
that the principal of all the Debentures shall be due and payable; or (iv)
consent to any amendment, modification or termination of the Indenture or the
Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of at least a majority in
Liquidation Amount of all Outstanding Preferred Securities; provided, however,
that where a consent under the Indenture would require the consent of each
Holder of Outstanding Debentures affected thereby, no such consent shall be
given by the Property Trustee without the prior written consent of each holder
of Preferred Securities. The Trustees shall not revoke any action previously
authorized or approved by a vote of the Holders of the Outstanding Preferred
Securities, except by a subsequent vote of the Holders of the Outstanding
Preferred Securities. The Property Trustee shall notify each Holder of the
Outstanding Preferred Securities of any notice of default received from the
Debenture Trustee with respect to the Debentures. In addition to obtaining the
foregoing approvals of the Holders of the Preferred Securities, prior to taking
any of the foregoing actions, the Trustees shall, at the expense of the
Depositor, obtain an Opinion of Counsel experienced in such matters to the
effect that the Trust shall continue to be classified as a grantor trust and not
as an association taxable as a corporation for United States federal income tax
purposes on account of such action.

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

     SECTION 602. NOTICE OF MEETINGS.

     Notice of all meetings of the Preferred Securityholders, stating the time,
place and purpose of the meeting, shall be given by the Property Trustee
pursuant to Section 1008 to each Preferred


                                       28

<PAGE>   36


Securityholder of record, at his registered address, at least 15 days and not
more than 90 days before the meeting. At any such meeting, any business properly
before the meeting may be so considered whether or not stated in the notice of
the meeting. Any adjourned meeting may be held as adjourned without further
notice.

     SECTION 603. MEETINGS OF PREFERRED SECURITYHOLDERS.

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

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

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

     SECTION 604. VOTING RIGHTS.

     Securityholders shall be entitled to one vote for each $25 of Liquidation
Amount represented by their Trust Securities (with any fractional multiple
thereof rounded up or down as the case may be to the closest integral multiple)
in respect of any matter as to which such Securityholders are entitled to vote.

     SECTION 605. PROXIES, ETC.

     At any meeting of Securityholders, any Securityholder entitled to vote
thereat may vote by proxy, provided that no proxy, shall be voted at any meeting
unless it shall have been placed on file with the Administrative Trustees, or
with such other officer or agent of the Trust as the Administrative Trustees may
direct, for verification prior to the time at which such vote shall be taken.
Only Holders of record shall be entitled to vote. When Trust Securities are held
jointly by several persons, any one of them may vote at any meeting in person or
by proxy in respect of such Trust Securities, but if more than one of them shall
be present at such meeting in person or by proxy, and such joint owners or their
proxies so present disagree as to any vote to be cast, such vote shall not be
received in respect of such Trust Securities. A proxy purporting to be executed
by or on


                                       29

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

     SECTION 606. SECURITYHOLDER ACTION BY WRITTEN CONSENT.

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

     SECTION 607. RECORD DATE FOR VOTING AND OTHER PURPOSES.

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

     SECTION 608. ACTS OF SECURITYHOLDERS.

     (a) Any request, demand, authorization, direction, notice, consent, waiver
or other action provided or permitted by this Trust Agreement to be given, made
or taken by Securityholders may be embodied in and evidenced by one or more
instruments of substantially similar tenor signed by such Securityholders or
owners in person or by an agent duly appointed in writing; and, except as
otherwise expressly provided herein, such action shall become effective when
such instrument or instruments are delivered to an Administrative Trustee. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Securityholders
signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any
purpose of this Trust Agreement and (subject to Section 801) conclusive in favor
of the Trustees, if made in the manner provided in this Section 608.

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


                                       30

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

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

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

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

     SECTION 609. INSPECTION OF RECORDS.

     Upon reasonable notice to the Administrative Trustees and the Property
Trustee, the records of the Trust shall be open to inspection at the principal
executive office of the Trust (as indicated in Section 202) by record holders of
the Trust Securities during normal business hours for any purpose reasonably
related to such record holder's interest as a record holder.

     SECTION 703. REPRESENTATIONS AND WARRANTIES OF DEPOSITOR.

     The Depositor hereby represents and warrants for the benefit of the
Securityholders that:

     (a)  the Trust Securities Certificates issued on the Closing Date or the
Option Closing Date, if applicable, on behalf of the Trust have been duly
authorized and, shall have been, duly and validly executed, issued and delivered

                                  ARTICLE VIII
                                    TRUSTEES

     SECTION 801. CERTAIN DUTIES AND RESPONSIBILITIES.

     (a) The duties and responsibilities of the Trustees shall be as provided by
this Trust Agreement and, in the case of the Property Trustee, by the Trust
Indenture Act. Notwithstanding the foregoing, no provision of this Trust
Agreement shall require the Trustees to expend or risk their own funds or
otherwise incur any financial liability in the performance of any of their
duties hereunder, or in the exercise of any of their rights or powers, if they
shall have reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to
it. No Administrative Trustee nor the Delaware Trustee shall be liable for its
act or omissions hereunder except as a result of its own gross negligence or
willful misconduct. The Property Trustee's liability shall be determined under
the Trust Indenture Act. Whether or not therein expressly so provided, every
provision of this Trust Agreement relating to the conduct or affecting the
liability of or affording protection to the Trustees shall be subject to the
provisions of this Section 801. To the extent that, at law or in equity, the
Delaware Trustee or an Administrative Trustee has duties (including fiduciary
duties) and liabilities relating thereto to the Trust or to the Securityholders,
the Delaware Trustee or such Administrative Trustee shall not be liable to the
Trust or to any Securityholder for such Trustee's good faith reliance on the
provisions of this Trust Agreement. The provisions of this Trust Agreement, to
the extent that they restrict the duties and liabilities of the Delaware Trustee
or the Administrative Trustees otherwise existing at law or in equity, are
agreed by the Depositor and the Securityholders to replace such other duties and
liabilities of the Delaware Trustee or the Administrative Trustees, as the case
may be.

     (b)  All payments made by the Property Trustee or a Paying Agent in respect
of the Trust Securities shall be made only from the revenue and proceeds from
the Trust Property and only to the extent that there shall be sufficient revenue
or proceeds from the Trust Property to enable the


                                       34


<PAGE>   42

Property Trustee or a Paying Agent to make payments in accordance with the terms
hereof. Each Securityholder, by its acceptance of a Trust Security, agrees that
it shall look solely to the revenue and proceeds from the Trust Property to the
extent legally available for distribution to it as herein provided and that the
Trustees are not personally liable to it for any amount distributable in respect
of any Trust Security or for any other liability in respect of any Trust
Security. This Section 801(b) does not limit the liability of the Trustees
expressly set forth elsewhere in this Trust Agreement or, in the case of the
Property Trustee, in the Trust Indenture Act.

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

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

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

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

          (iv) the Property Trustee shall not be liable for any interest on any
               money received by it except as it may otherwise agree with the
               Depositor and money held by the Property Trustee need not be
               segregated from other funds held by it except in relation to the
               Payment Account maintained by the Property Trustee pursuant to
               Section 301 and except to the extent otherwise required by law;
               and

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

     SECTION 802. CERTAIN NOTICES.

     (a) Within five Business Days after the occurrence of any Event of Default
actually known to the Property Trustee, the Property Trustee shall transmit, in
the manner and to the extent provided in Section 1008, notice of such Event of
Default to the Securityholders, the Administrative Trustees and the Depositor,
unless such Event of Default shall have been cured or waived. For purposes of
this Section 802 the term "Event of Default" means any event that is, or after
notice or lapse of time or both would become, an Event of Default.

     (b) The Administrative Trustees shall transmit, to the Securityholders in
the manner and to the extent provided in Section 1008, notice of the Depositor's
election to begin or further extend an Extended Interest Payment Period on the
Debentures (unless such election shall have been revoked) within the time
specified for transmitting such notice to the holders of the Debentures pursuant
to the Indenture as originally executed.

     SECTION 803. CERTAIN RIGHTS OF PROPERTY TRUSTEE.

     Subject to the provisions of Section 801:

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

     (b) if (i) in performing its duties under this Trust Agreement the Property
Trustee is required to decide between alternative courses of action; or (ii) in
construing any of the provisions of this Trust Agreement the Property Trustee
finds the same ambiguous or inconsistent with other provisions contained herein;
or (iii) the Property Trustee is unsure of the application of any provision of
this Trust Agreement, then, except as to any matter as to which the Preferred
Securityholders are entitled to vote under the terms of this Trust Agreement,
the Property Trustee shall deliver a notice to the Depositor requesting written
instructions of the Depositor as to the course of action to be taken and the
Property Trustee shall take such action, or refrain from taking such action, as
the Property Trustee shall be instructed in writing to take, or to refrain from
taking, by the Depositor; provided, however, that if the Property Trustee does
not receive such instructions of the Depositor within 10 Business Days after it
has delivered such notice, or such reasonably shorter period of time set forth
in such notice (which to the extent practicable shall not be less than 2
Business Days), it may, but shall be under no duty to, take or refrain from
taking such action not inconsistent with this Trust Agreement as it shall deem
advisable and in the best interests of the Securityholders, in which event the
Property Trustee shall have no liability except for its own bad faith,
negligence or willful misconduct;

                                       36
<PAGE>   44

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

     (d) whenever in the administration of this Trust Agreement, the Property
Trustee shall deem it desirable that a matter be established before undertaking,
suffering or omitting any action hereunder, the Property Trustee (unless other

its part, request and conclusively rely upon an Officer's Certificate which,
upon receipt of such request, shall be promptly delivered by the Depositor or
the Administrative Trustees;

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

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

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

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

or matters as it may see fit;

     (i) the Property Trustee may execute any of the trusts or powers hereunder
or perform any duties hereunder either directly or by or through its agents or
attorneys, and the Property Trustee shall not be liable for the default or

shall be responsible for its own negligence or recklessness with respect to
selection of any agent or attorney appointed by it hereunder;

     (j) whenever in the administration of this Trust Agreement the Property
Trustee shall deem it desirable to receive instructions with respect to
enforcing any remedy or right or taking any other action hereunder the Property
Trustee (i) may request instructions from the Holders of the Trust Securities
which instructions may only be given by the Holders of the same proportion in

                                       37
<PAGE>   45

Liquidation Amount of the Trust Securities as would be entitled to direct the
Property Trustee under the terms of the Trust Securities in respect of such
remedy, right or action; (ii) may refrain from enforcing such remedy or right or
taking such other action until such instructions are received; and (iii) shall
be protected in acting in accordance with such instructions; and

     (k) except as otherwise expressly provided by this Trust Agreement, the
Property Trustee shall not be under any obligation to take any action that is
discretionary under the provisions of this Trust Agreement. No provision of this
Trust Agreement shall be deemed to impose any duty or obligation on the Property
Trustee to perform any act or acts or exercise any right, power, duty or
obligation conferred or imposed on it, in any jurisdiction in which it shall be
illegal, or in which the Property Trustee shall be unqualified or incompetent in
accordance with applicable law, to perform any such act or acts, or to exercise

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

Trust with the same rights it would have if it were not a Trustee or such other
agent.

     SECTION 806. COMPENSATION; INDEMNITY; FEES.

     The Depositor agrees:

     (a) to pay to the Trustees from time to time compensation for all services

condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section 807,
the combined capital and surplus of such Person shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Property Trustee with respect to the Trust
Securities shall cease to be eligible in accordance with the provisions of this
Section 807, it shall resign immediately in the manner and with the effect

the meaning of the Trust Indenture Act, the Property Trustee shall either
eliminate such interest or resign, to the extent

                                       39
<PAGE>   47

     SECTION 809. CO-TRUSTEES AND SEPARATE TRUSTEE.

     (a) Unless a Debenture Event of Default shall have occurred and be
continuing, at any time or times, for the purpose of meeting the legal
requirements of the Trust Indenture Act or of any jurisdiction in which any part
of the Trust Property may at the time be located, the Depositor shall have power
to appoint, and upon the written request of the Property Trustee, the Depositor
shall for such purpose join with the Property Trustee in the execution, delivery
and performance of all instruments and agreements necessary or proper to
appoint, one or more Persons approved by the Property Trustee either to act as
co-trustee, jointly with the Property Trustee, of all or any part of such Trust
Property, or to the extent required by law to act as separate trustee of any
such property, in either case with such powers as may be provided in the
instrument of appointment, and to vest in such Person or Persons in the capacity
aforesaid, any property, title, right or power deemed necessary or desirable,
subject to the other provisions of this Section 809. If the Depositor does not
join in such appointment within 15 days after the receipt by it of a request so
to do, or in case a Debenture Event of Default has occurred and is continuing,
the Property Trustee alone shall have power to make such appointment. Any
co-trustee or separate trustee appointed pursuant to this Section 809 shall
either be (i) a natural person who is at least 21 years of age and a resident of
the United States; or (ii) a legal entity with its principal place of business
in the United States that shall act through one or more persons authorized to
bind such entity.

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

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

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

          (ii) The rights, powers, duties and obligations hereby conferred or
               imposed upon the Property Trustee in respect of any property
               covered by such appointment shall be conferred or imposed upon
               and exercised or performed by the Property Trustee or by the
               Property Trustee and such co-trustee or separate trustee jointly,
               as shall be provided in the instrument appointing such co-trustee
               or separate trustee, except to the extent that under any law of
               any jurisdiction in which any particular act is to be performed,
               the Property
                                       40
<PAGE>   48


                 Trustee shall be incompetent or unqualified to perform such
                 act, in which event such rights, powers, duties and obligations
                 shall be exercised and performed by such co-trustee or separate
                 trustee.

          (iii)  The Property Trustee at any time, by an instrument in
                 writing executed by it, with the written concurrence of the
                 Depositor, may accept the resignation of or remove any
                 co-trustee or separate trustee appointed under this Section
                 809, and, in case a Debenture Event of Default has occurred and
                 is continuing, the Property Trustee shall have the power to
                 accept the resignation of, or remove, any such co-trustee or
                 separate trustee without the concurrence of the Depositor. Upon
                 the written request of the Property Trustee, the Depositor
                 shall join with the Property Trustee in the execution, delivery
                 and performance of all instruments and agreements necessary or
                 proper to effectuate such resignation or removal. A successor
                 to any co-trustee or separate trustee so resigned or removed
                 may be appointed in the manner provided in this Section 809.

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


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


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

     SECTION 810. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

     (a) No resignation or removal of any Trustee (the "Relevant Trustee") and
no appointment of a successor Trustee pursuant to this Article VIII shall become
effective until the acceptance of appointment by the successor Trustee in
accordance with the applicable requirements of Section 811.

     (b) Subject to the immediately preceding paragraph, the Relevant
Trustee may resign at any time with respect to the Trust Securities by giving
written notice thereof to the Securityholders. If the instrument of acceptance
by the successor Trustee required by Section 811 shall not have been delivered
     to the Relevant Trustee within 30 days after the giving of such notice of
resignation, the Relevant Trustee may petition, at the expense of the Depositor,
any court of competent jurisdiction for the appointment of a successor Relevant
Trustee with respect to the Trust Securities.

     (c) Unless a Debenture Event of Default shall have occurred and be
continuing, any Trustee may be removed at any time by Act of the Common
Securityholder. If a Debenture Event of Default shall have occurred and be
continuing, the Property Trustee or the Delaware Trustee, or both of them, may
be removed at such time by Act of the Holders of a majority in Liquidation

                                       41
<PAGE>   49
Amount of the Preferred Securities, delivered to the Relevant Trustee (in its
individual capacity and on behalf of the Trust). An Administrative Trustee may
be removed by the Common Securityholder at any time.

     (d) If any Trustee shall resign, be removed or become incapable of acting
as Trustee, or if a vacancy shall occur in the office of any Trustee for any
cause, at a time when no Debenture Event of Default shall have occurred and be
continuing, the Common Securityholder, by Act of the Common Securityholder
delivered to the retiring Trustee, shall promptly appoint a successor Trustee or
Trustees with respect to the Trust Securities and the Trust, and the successor
Trustee shall comply with the applicable requirements of Section 811. If the
Property Trustee or the Delaware Trustee shall resign, be removed or become
incapable of continuing to act as the Property Trustee or the Delaware Trustee,
as the case may be, at a time when a Debenture Event of Default shall have
occurred and is continuing, the Preferred Securityholders, by Act of the
Securityholders of a majority in Liquidation Amount of the Preferred Securities
then Outstanding delivered to the retiring Relevant Trustee, shall promptly
appoint a successor Relevant Trustee or Trustees with respect to the Trust
Securities and the Trust, and such successor Trustee shall comply with the
applicable requirements of Section 811. If an Administrative Trustee shall
resign, be removed or become incapable of acting as Administrative Trustee, at a
time when a Debenture Event of Default shall have occurred and be continuing,
the Common Securityholder, by Act of the Common Securityholder delivered to an
Administrative Trustee, shall promptly appoint a successor Administrative
Trustee or Administrative Trustees with respect to the Trust Securities and the
Trust, and such successor Administrative Trustee or Administrative Trustees
shall comply with the applicable requirements of Section 811. If no successor
Relevant Trustee with respect to the Trust Securities shall have been so
appointed by the Common Securityholder or the Preferred Securityholders and
accepted appointment in the manner required by Section 811, any Securityholder
who has been a Securityholder of Trust Securities on behalf of himself and all
others similarly situated may petition a court of competent jurisdiction for the
appointment Trustee with respect to the Trust Securities.

     (e) The Property Trustee shall give notice of each resignation and each
removal of a Trustee and each appointment of a successor Trustee to all
Securityholders in the manner provided in Section 1008 and shall give notice to
the Depositor. Each notice shall include the name of the successor Relevant
Trustee and the address of its Corporate Trust office if it is the Property
Trustee.

     (f) Notwithstanding the foregoing or any other provision of this Trust
Agreement, in the event any Administrative Trustee or a Delaware Trustee who is
a natural person dies or becomes, in the opinion of the Depositor, incompetent
or incapacitated, the vacancy created by such death, incompetence or incapacity
may be filled by (a) the unanimous act of remaining Administrative Trustees if
there are at least two of them; or (b) otherwise by the Depositor (with the
successor in each case being a Person who satisfies the eligibility requirement
for Administrative Trustees set forth in Section 807).

     SECTION 811. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

                                       42
<PAGE>   50

     (a) In case of the appointment hereunder of a successor Relevant Trustee
with respect to the Trust Securities and the Trust, the retiring Relevant
Trustee and each successor Relevant Trustee with respect to the Trust Securities
shall execute and deliver an instrument hereto wherein each successor Relevant
Trustee shall accept such appointment and which shall contain such provisions as
shall be necessary or desirable to transfer and confirm to, and to vest in, each
successor Relevant Trustee all the rights, powers, trusts and duties of the
retiring Relevant Trustee with respect to the Trust Securities and the Trust and
upon the execution and delivery of such instrument the resignation or removal of
the retiring Relevant Trustee shall become effective to the extent provided
therein and each such successor Relevant Trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, trusts and
duties of the retiring Relevant Trustee with respect to the Trust Securities and
the Trust; but, on request of the Trust or any successor Relevant Trustee such
retiring Relevant Trustee shall duly assign, transfer and deliver to such
successor Relevant Trustee all Trust Property, all proceeds thereof and money
held by such retiring Relevant Trustee hereunder with respect to the Trust
Securities and the Trust.

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

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

     SECTION 812. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

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

     SECTION 813. PREFERENTIAL COLLECTION OF CLAIMS AGAINST DEPOSITOR OR TRUST.

     If and when the Property Trustee or the Delaware Trustee shall be or become
a creditor of the Depositor or the Trust (or any other obligor upon the
Debentures or the Trust Securities), the Property Trustee or the Delaware
Trustee, as the case may be, shall be subject to and shall take all actions
necessary in order to comply with the provisions of the Trust Indenture Act
regarding the collection of claims against the Depositor or Trust (or any such
other obligor).

     SECTION 814. REPORTS BY PROPERTY TRUSTEE.

                                       43
<PAGE>   51


     (a)  Not later than July 31 of each year commencing with July 31, 2001, the
Property Trustee shall transmit to all Securityholders in accordance with
Section 1008, and to the Depositor, a brief report dated as of June 30 with
respect to:

          (i)  its eligibility under Section 807 or, in lieu thereof, if to the
               best of its knowledge it has continued to be eligible under said
               Section, a written statement to such effect; and

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

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

     (c) A copy of each such report shall, at the time of such transmission to
Holders, be filed by the Property Trustee with the American Stock Exchange, and
each national securities exchange or other organization upon which the Trust
Securities are listed, and also with the Commission and the Depositor.

     SECTION 815. REPORTS TO THE PROPERTY TRUSTEE.

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

     SECTION 816. EVIDENCE OF COMPLIANCE WITH CONDITIONS PRECEDENT.

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

     SECTION 817. NUMBER OF TRUSTEES.

     (a) The number of Trustees shall be five, provided that the Holder of all
of the Common Securities by written instrument may increase or decrease the
number of Administrative Trustees. The Property Trustee and the Delaware Trustee
may be the same Person.
                                       44
<PAGE>   52

     (b) If a Trustee ceases to hold office for any reason and the number of
Administrative Trustees is not reduced pursuant to Section 817(a), or if the
number of Trustees is increased pursuant to Section 817(a), a vacancy shall
occur. The vacancy shall be filled with a Trustee appointed in accordance with
Section 810.

     (c) The death, resignation, retirement, removal, bankruptcy, incompetence
or incapacity to perform the duties of a Trustee shall not operate to annul the
Trust. Whenever a vacancy in the number of Administrative Trustees shall occur,
until such vacancy is filled by the appointment of an Administrative Trustee in
accordance with Section 810, the Administrative Trustees in office, regardless
of their number (and notwithstanding any other provision of this Agreement),
shall have all the powers granted to the Administrative Trustees and shall
discharge all the duties imposed upon the Administrative Trustees by this Trust
Agreement.

     SECTION 818. DELEGATION OF POWER.

     (b) The Administrative Trustees shall have power to delegate from time to
time to such of their number or to the Depositor the doing of such things and
the execution of such instruments either in the name of the Trust or the names
of the Administrative Trustees or 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 819. VOTING.

     Except as otherwise provided in this Trust Agreement, the consent or
approval of the Administrative Trustees shall require consent or approval by not
less than a majority of the Administrative Trustees, unless there are only two,

     SECTION 901. TERMINATION UPON EXPIRATION DATE.

     Unless earlier dissolved, the Trust shall automatically dissolve on,

Property in accordance with Section 904.

     SECTION 902. EARLY TERMINATION.

     The first to occur of any of the following events is an "Early Termination
Event:"

                                       45
<PAGE>   53


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

     (b) delivery of written direction to the Property Trustee by the Depositor
at any time (which direction is wholly optional and within the discretion of the
Depositor, subject to Depositor having received prior approval of the Board of
Governors of the Federal Reserve System if so required under applicable
guidelines, policies or regulations thereof) to dissolve the Trust and
distribute the Debentures to Securityholders in exchange for the Preferred
Securities in accordance with Section 904;

     (c) the redemption of all of the Preferred Securities in connection with
the redemption of all of the Debentures (whether upon a Debenture Redemption
Date or the maturity of the Debenture); or

     (d) an order for dissolution of the Trust shall have been entered by a
court of competent jurisdiction.

     SECTION 903. TERMINATION.

     The respective obligations and responsibilities of the Trustees and the
Trust created and continued hereby shall terminate upon the latest to occur of
the following: (a) the distribution by the Property Trustee to Securityholders
upon the liquidation of the Trust pursuant to Section 904, or upon the
redemption of all of the Trust Securities pursuant to Section 402, of all
amounts required to be distributed hereunder upon the final payment of the Trust
Securities; (b) the payment of any expenses owed by the Trust; (c) the discharge
of all administrative duties of the Administrative Trustees, including the
performance of any tax reporting obligations with respect to the Trust or the
Securityholders; and (d) the filing of a Certificate of Cancellation by an
Administrative Trustee under the Business Trust Act.

     SECTION 904. LIQUIDATION.

     (a) If an Early Termination Event specified in clause (a), (b), or (d) of
Section 902 occurs or upon the Expiration Date, the Trust shall be liquidated by
the Trustees as expeditiously as the Trustees determine to be possible by
distributing, after satisfaction of liabilities to creditors of the Trust as
provided by applicable law, to each Securityholder a Like Amount of Debentures,
subject to Section 904(d). Notice of liquidation shall be given by the Property
Trustee by first-class mail, postage prepaid, mailed not later than 30 nor more
than 60 days prior to the Liquidation Date to each Holder of Trust Securities at
such Holder's address appearing in the Securities Register. All notices of
liquidation shall:

               (i)  state the Liquidation Date;

               (ii) state that from and after the Liquidation Date, the Trust
                    Securities shall no longer be deemed to be Outstanding and
                    any Trust Securities Certificates not

                                       46
<PAGE>   54
                surrendered for exchange shall be deemed to represent a Like
                Amount of Debentures; and

          (iii) provide such information with respect to the mechanics by which
                Holders may exchange Trust Securities Certificates for
                Debentures, or, if Section 904(d) applies, receive a Liquidation
                Distribution, as the Administrative Trustees or the Property
                Trustee shall deem appropriate.

     (b) Except where Section 902(c) or 904(d) applies, in order to effect the
liquidation of the Trust and distribution of the Debentures to Securityholders,
the Property Trustee shall establish a record date for such distribution (which
shall be not more than 45 days prior to the Liquidation Date) and, either itself
acting as exchange agent or through the appointment of a separate exchange
agent, shall establish such procedures as it shall deem appropriate to effect
the distribution of Debentures in exchange for the Outstanding Trust Securities
Certificates.

     (c) Except where Section 902(c) or 904(d) applies, after the Liquidation
Date, (i) the Trust Securities shall no longer be deemed to be outstanding; (ii)
certificates representing a Like Amount of Debentures shall be issued to holders
of Trust Securities Certificates upon surrender of such certificates to the
Administrative Trustees or their agent for exchange; (iii) the Depositor shall
use its reasonable efforts to have the Debentures listed on the American Stock
Exchange or on such other securities exchange or other organization as the
Preferred Securities are then listed or traded; (iv) any Trust Securities
Certificates not so surrendered for exchange shall be deemed to represent a Like
Amount of Debentures, accruing interest at the rate provided for in the
Debentures from the last Distribution Date on which a Distribution was made on
such Trust Securities Certificates until such certificates are so surrendered
(and until such certificates are so surrendered, no payments of interest or
principal shall be made to holders of Trust Securities Certificates with respect
to such Debentures); and (v) all rights of Securityholders holding Trust
Securities shall cease, except the right of such Securityholders to receive
Debentures upon surrender of Trust Securities Certificates.

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

                                       47
<PAGE>   55


or termination pro rata (determined as aforesaid) with Holders of Preferred
Securities, except that, if a Debenture Event of Default has occurred and is
continuing, the Preferred Securities shall have a priority over the Common
Securities.

     SECTION 905. MERGERS, CONSOLIDATIONS, AMALGAMATIONS OR REPLACEMENTS OF THE
TRUST.

     The Trust may not merge with or into, consolidate, amalgamate, or be
replaced by, or convey, transfer or lease its properties and assets
substantially as an entirety to any corporation or other Person, except pursuant
to this Section 905. At the request of the Depositor, with the consent of the
Administrative Trustees and without the consent of the holders of the Preferred
Securities, the Property Trustee or the Delaware Trustee, the Trust may merge
with or into, consolidate, amalgamate, be replaced by or convey, transfer or
lease its properties and assets substantially as an entirety to a trust
organized as such under the laws of any state; provided, that (i) such successor
entity either (a) expressly assumes all of the obligations of the Trust with
respect to the Preferred Securities; or (b) substitutes for the Preferred
Securities other securities having substantially the same terms as the Preferred
Securities (the "Successor Securities) so long as the Successor Securities rank
the same as the Preferred Securities rank in priority with respect to
distributions and payments upon liquidation, redemption and otherwise; (ii) the
Depositor expressly appoints a trustee of such successor entity possessing
substantially the same powers and duties as the Property Trustee as the holder
of the Debentures; (iii) the Successor Securities are listed or traded, or any
Successor Securities shall be listed or traded upon notification of issuance, on
any national securities exchange or other organization on which the Preferred
Securities are then listed, if any; (iv) such merger, consolidation,
amalgamation, replacement, conveyance, transfer or lease does not adversely
affect the rights, preferences and privileges of the holders of the Preferred
Securities (including any Successor Securities) in any material respect; (v)
such successor entity has a purpose substantially identical to that of the
Trust; (vi) prior to such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease, the Depositor has received an Opinion of Counsel
to the effect that (a) such merger, consolidation, amalgamation, replacement,
conveyance, transfer or lease does not adversely affect the rights, preferences
and privileges of the holders of the Preferred Securities (including any
Successor Securities) in any material respect; and (b) following such merger,
consolidation, amalgamation, replacement, conveyance, transfer or lease, neither
the Trust nor such successor entity shall be required to register as an
"investment company" under the Investment Company Act; and (vii) the Depositor
owns all of the Common Securities of such successor entity and guarantees the
obligations of such successor entity under the Successor Securities at least to
the extent provided by the Guarantee. Notwithstanding the foregoing, the Trust
shall not, except with the consent of holders of 100% in Liquidation Amount of
the Preferred Securities, consolidate, amalgamate, merge with or into, or be
replaced by or convey, transfer or lease its properties and assets substantially
as an entirety to any other Person or permit any other Person to consolidate,
amalgamate, merge with or into, or replace it if such consolidation,
amalgamation, merger or replacement would cause the Trust or the successor
entity to be classified as other than a grantor trust for United States federal
income tax purposes.

                            MISCELLANEOUS PROVISIONS

     SECTION 1001. LIMITATION OF RIGHTS OF SECURITYHOLDERS.

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

     SECTION 1002. AMENDMENT.

     (a) This Trust Agreement may be amended from time to time by the Trustees
and the Depositor, without the consent of any Securityholders, (i) as provided
in Section 811 with respect to acceptance of appointment by a successor Trustee;
(ii) to cure any ambiguity, correct or supplement any provision herein or
therein which may be inconsistent with any other provision herein or therein, or
to make any other provisions with respect to matters or questions arising under
this Trust Agreement, that shall not be inconsistent with the other provisions
of this Trust Agreement; or (iii) to modify, eliminate or add to any provisions
of this Trust Agreement to such extent as shall be necessary to ensure that the
Trust shall 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 shall not be required to register as an "investment
company" under the Investment Company Act; provided, however, that in the case
of clause (ii), such action shall not adversely affect in any material respect
the interests of any Securityholder, and any amendments of this Trust Agreement
shall become effective when notice thereof is given to the Securityholders.

     (b) Except as provided in Section 601(c) or Section 1002(c) hereof, any
provision of this Trust Agreement may be amended by the Trustees and the
Depositor (i) with the consent of Trust Securityholders representing not less
than a majority (based upon Liquidation Amounts) of the Trust Securities then
Outstanding; and (ii) upon 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 shall not affect the Trust's status
as a grantor trust for United States federal income tax purposes or the Trust's
exemption from status of an "investment company" under the Investment Company
Act.

     (c) In addition to and notwithstanding any other provision in this Trust
Agreement, without the consent of each affected Securityholder (such consent
being obtained in accordance with Section 603 or 606 hereof), this Trust
Agreement may not be amended to (i) change the amount or timing of any
Distribution on the Trust Securities or otherwise adversely affect the amount of
any Distribution required to be made in respect of the Trust Securities as of a
specified date; or (ii) restrict the right of a Securityholder to institute suit
for the enforcement of any such payment on or after such date; notwithstanding
any other provision herein, without the unanimous consent of the Securityholders
(such consent being obtained in accordance with Section 603 or 606 hereof), this
paragraph (c) of this Section 1002 may not be amended.

     (d) Notwithstanding any other provisions of this Trust Agreement, no
Trustee shall enter into or consent to any amendment to this Trust Agreement

status of an "investment company" under the Investment Company Act or to fail or
cease to be classified as a grantor trust for United States federal income tax
purposes.

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

THEREOF).

     SECTION 1005. PAYMENTS DUE ON NON-BUSINESS DAY.

     If the date fixed for any payment on any Trust Security shall be a day that

be made on the next succeeding day which is a Business Day, except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day (and without any reduction of interest
