Proxy Statement/Prospectus

   The boards of directors of Marshall & Ilsley Corporation and Century
Bancshares, Inc. have agreed that Century Bancshares will merge with and into
Marshall & Ilsley, with Marshall & Ilsley being the surviving corporation. If
the merger is completed, each share of Century Bancshares common stock will be
converted into shares of Marshall & Ilsley common stock having a value of
approximately $7.40, although Century Bancshares shareholders may elect to
receive cash for their shares, up to an aggregate amount of approximately
$22.82 million. We will determine the exact exchange ratio with a formula based
on the trading price of Marshall & Ilsley common stock during the 10 trading
days up to and including the second trading day prior to the merger. The
exchange ratio is intended to provide a value of approximately $7.40 per share
of Century Bancshares common stock. Cash will be paid in lieu of issuing
fractional shares.

   Based on the $       average price per share of Marshall & Ilsley common
stock during the 10 trading days up to and including the second trading day
prior to       , 2002, the exchange ratio would equal        of a share of
Marshall & Ilsley common stock for each share of your Century Bancshares common
stock.

approve the merger and the agreement and plan of merger, including the form of

           QUESTIONS AND ANSWERS ABOUT THIS DOCUMENT AND THE MERGER

Q. What is the purpose of this document?

A. This document serves as both a proxy statement of Century Bancshares and
   prospectus of Marshall & Ilsley for the issuance of its common stock in the
   merger. As a proxy statement, this document is being provided to you by
   Century Bancshares because the board of directors of Century Bancshares is
   soliciting your proxy for use at the special meeting of shareholders called
   to vote on the proposed merger of Century Bancshares with and into Marshall
   & Ilsley. When we use the term merger agreement in this document, we are
   referring, collectively, to the agreement and plan of merger, a copy of
   which is included in this document as Appendix A, and the form of plan of
   merger constituting a part thereof, a copy of which is included in this
   document as Appendix B.

   As a prospectus, this document is being provided to you by Marshall & Ilsley
   because Marshall & Ilsley is offering shares of its common stock in exchange
   for your shares of Century Bancshares common stock in connection with the
   merger.

Q. Why do Century Bancshares and Marshall & Ilsley want to merge?

A. The Century Bancshares board of directors believes that the merger is
   consistent with Century Bancshares's goal of achieving superior shareholder
   returns and will create a more competitive company better able to serve its
   customers. The Marshall & Ilsley board of directors believes that the merger
   will enable Marshall & Ilsley to expand its operations in the Minneapolis,
   Minnesota area and strengthen its banking franchise through Century
   Bancshares's strong commercial and retail banking presence in the
   Minneapolis area.

Q. What will I receive for my Century Bancshares shares of common stock?

A. You will receive a fraction of a share of Marshall & Ilsley common stock
   having a total value of approximately $7.40 for each share of Century
   Bancshares common stock you own at the effective time of the merger. The
   exact number of shares of Marshall & Ilsley common stock you will receive in
   exchange for your shares of Century Bancshares common stock will be
   determined at the time of the merger based on the average trading price of
   Marshall & Ilsley common stock during a measurement period of 10 trading
   days up to and including the second trading day before the merger. Marshall
   & Ilsley will not issue any fractional shares. Instead, you will receive
   cash in lieu of any fractional share owed to you.

   You may also elect to receive cash in exchange for your shares of Century
   Bancshares common stock. If you make such an election, then you will receive
   a cash amount of approximately $7.40 for each of your shares of Century
   Bancshares common stock. If you make such an election and if the amount of
   cash that holders of shares of Century Bancshares common stock elect to
   receive in exchange for their shares exceeds a total of approximately $22.82
   million, then the amount of cash that you will receive for each share will
   be subject to a pro rata reduction, and you will receive a number of shares
   of Marshall & Ilsley common stock with a value equal to the amount of that
   reduction.

   Each previously issued and outstanding share of Marshall & Ilsley common
   stock will remain issued and outstanding and will not be converted or
   exchanged in the merger.

Q. How do I elect to receive cash for my shares?

A. A form of election has been included with this proxy statement/prospectus.
   You may elect to receive cash for your shares of Century Bancshares common
   stock by completing and signing the enclosed form of election and submitting
   it to Continental Stock Transfer & Trust Company, our exchange agent, at
   17 Battery Place, 8/th/ Floor, New York, New York, 10004, by the election
   deadline, which is 5:00 p.m., Minneapolis time, on         ,       , 2002.
   If you have made an election to receive cash for your shares, you may at any
   time change or withdraw your election by written notice to the exchange
   agent prior to the election deadline. If you do not submit a properly

must be approved by the affirmative vote of at least a majority of the shares
of Series A and Series B Century Bancshares common stock outstanding at the
close of business on , 2002, voting together as a single class. As of that

outstanding Century Bancshares common stock. Each of these shareholders has
agreed, among other things, to vote its shares in favor of the merger and the
merger agreement.

exchange ratio is intended to provide a value of approximately $7.40 per share

the exchange ratio by dividing $7.40 by the average high and low sale price per
share of Marshall & Ilsley common stock for the 10 trading days ending on and
including the second trading day preceding such date. As of December 3, 2001,
the average trading price of Marshall & Ilsley common stock was $61.32 and as

entitled to receive as a result of the merger may be significantly higher or
lower than its current value or its value at the date of the special meeting.

Comparison of Unaudited Per Share Data

   The following table shows information about Marshall & Ilsley's and Century
Bancshares's net income per share, cash dividends per share and book value per
share, and similar information after giving effect to the merger. This
information is referred to below as "pro forma" information. In presenting the
pro forma information, Marshall & Ilsley and Century Bancshares assumed that we
had been merged as of the beginning of the earliest period presented. The pro
forma information gives effect to the merger under the purchase method of
accounting in accordance with currently existing accounting principles
generally accepted in the United States.

   Marshall & Ilsley used the exchange ratio of 0.1185 in computing the pro
forma combined and equivalent pro forma combined per share data. This exchange
ratio is intended to provide a value of approximately $7.40 per share of
Century Bancshares common stock, which includes an adjustment for the decrease
in the total merger consideration described above. We calculated the exchange
ratio by dividing $7.40 by the average of the average high and low sale price
per share of Marshall & Ilsley common stock on the NYSE for the 10 trading days
ending on and including the second trading day preceding December 19, 2001. As
of    , 2002, the average price of Marshall & Ilsley common stock was $   .

   Marshall & Ilsley expects that it will incur merger and integration charges
as a result of combining our companies. The pro forma information is helpful in
illustrating the financial characteristics of the combined company under one
set of assumptions. However, it does not reflect these merger and integration
charges and, accordingly, does not attempt to predict or suggest future
results. Also, it does not necessarily reflect what the historical results of
the combined company would have been had our companies been combined for the
periods presented.

   You should read the information in the following table together with the
historical financial information that Marshall & Ilsley has included in its
prior filings with the United States Securities and Exchange Commission. This
material has been incorporated into this document by reference to those
filings. See "Where You Can Find More Information" on page 52.

                                 RISK FACTORS

   In making your determination as to how to vote on the merger, you should
consider the following factors:

Risks Relating to the Merger

  You will not know the exact number of Marshall & Ilsley shares you will
  receive until the time of the merger.

   If you receive shares of Marshall & Ilsley common stock in exchange for your
shares of Century Bancshares common stock, we will calculate the number of
shares of Marshall & Ilsley common stock you will receive in exchange for each
of your shares of Century Bancshares common stock based on a formula provided
in the merger agreement. The number of Marshall & Ilsley shares you will
receive will depend, in part, on the average trading price of Marshall &
Ilsley's common stock during the 10 trading days up to and including the second
trading day prior to the effective time of the merger. The exact number of
Marshall & Ilsley shares you will receive for each of your shares of Century
Bancshares common stock will depend on the result of dividing approximately
$7.40 by the average trading price of Marshall & Ilsley common stock before the
merger. As a result, you must decide whether to approve the merger without
knowing the exact number of Marshall & Ilsley shares you will receive.

   For a complete description of how the number of Marshall & Ilsley shares you
will receive in the merger will be determined, see "The Merger--Merger
Consideration."

  The number of Marshall & Ilsley shares you receive will depend on the average
  trading price of Marshall & Ilsley common stock during the measurement period
  prior to the merger.

   If you receive shares of Marshall & Ilsley common stock in exchange for your
shares of Century Bancshares common stock, changes in the market price of
Marshall & Ilsley common stock before the merger will affect the exact number
of Marshall & Ilsley shares you will receive in exchange for your shares of
Century Bancshares common stock. The exchange ratio is intended to provide a
value of approximately $7.40 per share of Century Bancshares common stock. We
cannot predict the price at which Marshall & Ilsley common stock will trade
before the merger. Any number of factors could cause the market price of
Marshall & Ilsley common stock to change, including changes in general market
and economic conditions, changes in Marshall & Ilsley's business, operations
and prospects and changes in the regulatory environment. Many of these factors
are beyond our control. There are no "walk away" or termination rights in the
merger agreement that would permit Century Bancshares to terminate the merger
based on declines in the value of Marshall & Ilsley common stock.

  The value of the Marshall & Ilsley common stock you receive may be
  substantially lower than anticipated.

   The average trading price used to calculate the exchange ratio is likely to
be different from the closing price per share of Marshall & Ilsley common stock
at the effective time of the merger. As a result, if you receive shares of
Marshall & Ilsley common stock in exchange for your shares of Century
Bancshares common stock, the value of the Marshall & Ilsley common stock you
will be entitled to receive for each of your shares of Century Bancshares
common stock may be substantially lower than $7.40.

  Century Bancshares Shareholders will be diluted by the merger.

   The merger will dilute the ownership position of the present shareholders of
Century Bancshares. Based on the number of shares of Century Bancshares common
stock outstanding on the record dates of the special meeting and the average
trading price of $    per share of Marshall & Ilsley common stock on   , 2002,
Marshall & Ilsley will issue to Century Bancshares shareholders approximately
of a share of Marshall & Ilsley common stock in the merger (assuming no cash
elections are made). As a result, Century Bancshares shareholders will hold
approximately    percent of the Marshall & Ilsley common stock outstanding
immediately after the completion of the merger.

                                      11



  Omitted Industry Financial Information

   Century Bancshares has excluded certain financial disclosures required of
bank holding companies under rules promulgated by the Securities and Exchange
Commission from the Management's Discussion and Analysis of Financial Condition
and Results of Operations of Century Bancshares attached to this Proxy
Statement/Prospectus as Appendix D. The omitted industry financial information
relates to, among other things, certain disclosures as to Century Bancshares
investments and deposits. Marshall & Ilsley and Century Bancshares have
determined since Century Bancshares has not been required to make such
disclosures in the past to its shareholders, it has not compiled and would be
unable to create such financial information from existing financial records
without incurring considerable expense, effort and delay. Marshall & Ilsley and
Century Bancshares have determined the omission of certain bank holding company
financial disclosures is not material to the shareholders of Century Bancshares.

Post Merger Risks

  Share Price Fluctuation

   The share price of Marshall & Ilsley common stock on the New York Stock
Exchange is by its nature subject to the general price fluctuations in the
market for publicly traded equity securities. Such fluctuations are not
necessarily related to a change in the financial performance or condition of
Marshall & Ilsley.

  Marshall & Ilsley's future acquisitions will dilute your ownership of
  Marshall & Ilsley and may cause Marshall & Ilsley to become more susceptible
  to adverse economic events.

   Marshall & Ilsley has acquired other businesses with its common stock in the
past and intends to acquire or make investments in complementary businesses
with its common stock in the future. Future business acquisitions could be
material to Marshall & Ilsley. Marshall & Ilsley may issue additional shares of
common stock to pay for those acquisitions, which would dilute your ownership
interest in Marshall & Ilsley. Acquisitions also could require Marshall &
Ilsley to use substantial cash or other liquid assets or to incur debt. In
those events, Marshall & Ilsley could become more susceptible to economic
downturns and competitive pressures.

  If Marshall & Ilsley does not adjust to rapid changes in the financial
  services industry, then its financial performance may suffer.

   Marshall & Ilsley's ability to maintain its history of strong financial
performance and return on investment to shareholders will depend in part on
Marshall & Ilsley's ability to expand its scope of available financial services
as required to meet the needs and demands of its customers. In addition to the
challenge of attracting and retaining customers for traditional banking
services, Marshall & Ilsley's competitors now include securities dealers,
brokers, mortgage bankers, investment advisors and finance and insurance
companies that seek to offer one-stop financial services to their customers
that may include services that banks have not been able or allowed to offer to
their customers in the past. The increasingly competitive environment is
primarily a result of changes in regulation, changes in technology and product
delivery systems and the accelerating pace of consolidation among financial
service providers.

  Difficulties in combining the operations of acquired entities, including
  Century Bancshares, with Marshall & Ilsley's own operations may prevent
  Marshall & Ilsley from achieving the expected benefits from its acquisitions.

   Marshall & Ilsley may not be able to achieve fully the strategic objectives
and operating efficiencies in its various acquisitions, including Century
Bancshares. Inherent uncertainties exist in integrating the operations of an
acquired company into Marshall & Ilsley. In addition, the markets and
industries in which Marshall & Ilsley

                                      12



operates are highly competitive. Marshall & Ilsley also may lose key personnel,
either from the acquired entities or from itself, as a result of acquisitions.
These factors could contribute to Marshall & Ilsley not achieving the expected
benefits from its acquisitions within the desired time frames, if at all.

  Changes in interest rates could reduce Marshall & Ilsley's income and cash
  flows.

   Marshall & Ilsley's income and cash flows depend to a great extent on the
difference between the interest rates earned on interest-earning assets such as
loans and investment securities, and the interest rates paid on
interest-bearing liabilities such as deposits and borrowings. These rates are
highly sensitive to many factors which are beyond Marshall & Ilsley's control,
including general economic conditions and the policies of various governmental
and regulatory agencies, including, in particular, the Federal Reserve Board.
Changes in monetary policy, including changes in interest rates, will influence
the origination of loans, the purchase of investments, the generation of
deposits and the rates received on loans and investment securities and paid on
deposits. Fluctuations in these areas may adversely affect Marshall & Ilsley.

  Future governmental regulation and legislation could limit Marshall &
  Ilsley's future growth.

   Marshall & Ilsley and its subsidiaries are subject to extensive state and
federal regulation, supervision and legislation that govern almost all aspects
of the operations of Marshall & Ilsley and its subsidiaries. These laws may
change from time to time and are primarily intended for the protection of
consumers, depositors and the deposit insurance funds. Any changes to these
laws may negatively affect Marshall & Ilsley's ability to expand its services
and to increase the value of its business. While we cannot predict what effect
any presently contemplated or future changes in the laws or regulations or
their interpretations would have on Marshall & Ilsley, these changes could be
materially adverse to Marshall & Ilsley's shareholders.

  The long-term economic effects of recent terrorist attacks on the United
  States and an economic slowdown could negatively affect Marshall & Ilsley's
  financial condition.

   On September 11, 2001, New York City and Washington, D.C. suffered serious
terrorist attacks. The long-term economic impact of these acts has yet to be
determined, and the ultimate cost associated with these attacks and related
incidents may place significant burdens on the United States economy as a
whole. In addition, an overall economic slowdown could negatively impact the
purchasing and decision making activities of the financial institution
customers of Marshall & Ilsley's data processing subsidiary, Metavante
Corporation. If these acts or additional terrorist attacks or other factors
cause an overall economic decline, the financial condition and operating
results of Marshall & Ilsley could be materially adversely affected.

   The meeting is being held so that Century Bancshares shareholders may
consider and vote upon a proposal to approve the agreement and plan of merger
with Marshall & Ilsley, including the form of plan of merger constituting a
part thereof, and the merger of Century Bancshares with and into Marshall &
Ilsley contemplated by that agreement, and to transact any other business that
may properly come before the meeting or any adjournment or postponement of the
meeting. Approval of the proposal will constitute approval of the agreement and
plan of merger, the plan of merger and the transactions contemplated by that
agreement and plan, including the merger. A copy of the merger agreement and
plan of merger is contained in Appendix A and a copy of the plan of merger is
contained in Appendix B. When we use the term merger agreement in this
document, we are referring, collectively, to the agreement and plan of merger
and the form of plan of merger.

Record Date

   Only holders of record on Century Bancshares shares at the close of business
on     , 2002, are entitled to receive notice of and to vote at the Century
Bancshares special meeting or any adjournments or postponements of the meeting.
At the close of business on January    , 2002, there were 2,499,709 Series A
and 5,450,590 Series B, or, in aggregate, 7,950,299 shares of Century
Bancshares common stock outstanding, held by approximately 83 record holders.

Required Vote

   The affirmative vote of the holders of a majority of the Series A and Series
B shares of Century Bancshares common stock entitled to vote at the Century
Bancshares special meeting, voting together as a single class, is required to
approve the merger agreement and the merger. For each Series A or Series B
Century Bancshares share you held on the record date, you are entitled to one
vote on each proposal to be presented to shareholders at the meeting.
Abstentions and broker non-votes will have the effect of a vote against
approval of the merger and the merger agreement.

   Century Bancshares's board of directors believes that the merger is fair to
and in the best interests of Century Bancshares and its shareholders and has
unanimously approved the merger and the merger agreement. Century Bancshares's
board unanimously recommends that the Century Bancshares shareholders vote
"FOR" approval of the merger and the merger agreement.

Proxies

   The persons named on the enclosed proxy card will vote all Century
Bancshares shares represented by properly executed proxies that have not been
revoked. If no instructions are indicated, the persons named will vote the
shares "FOR" approval of the merger and the merger agreement. The affirmative
vote of a majority of the shares entitled to vote is required to approve the
merger and the merger agreement. Proxies which are marked "ABSTAIN" will have
the effect of a vote "AGAINST" approval of the merger and the merger agreement.

                                      14



   If your shares are held in an account at a brokerage firm or bank, you must
instruct it on how to vote your shares. Your broker or bank will vote your
shares only if you provide instructions on how to vote by following the
information provided to you by your broker or bank.

   Because approval of the merger and the merger agreement requires the
affirmative vote of at least a majority of all votes entitled to be cast,
abstentions, failures to vote and broker non-votes will have the same effect as
a vote against approval of the merger and the merger agreement.

   Century Bancshares does not know of any matter not described in the notice
of meeting that is expected to come before the meeting. If, however, any other
matters are properly presented for action at the meeting, the persons named as
proxies will vote the proxies in their discretion, unless authority is withheld.

   A shareholder may revoke a proxy at any time prior to its exercise by filing
written notice with an officer of Century Bancshares or by signing and filing
with an officer of Century Bancshares a later dated proxy. Neither attendance
at the meeting or attempting to vote the shares in person at the meeting will
revoke a proxy.

   Do NOT send in your Century Bancshares stock certificates with your proxy
card. As soon as practicable after the completion of the merger, the exchange
agent will mail to you transmittal forms with instructions for exchanging your
Century Bancshares stock certificates for the merger consideration.

Solicitation of Proxies

   Century Bancshares will pay all the costs of soliciting proxies, except that
Marshall & Ilsley will share equally in the expense of printing and filing this
document and all SEC, NYSE and other regulatory filing fees in connection with
this document. Century Bancshares will reimburse brokerage firms and other
custodians, nominees and fiduciaries for reasonable expenses, if any, incurred
by them in sending proxy materials to the beneficial owners of Century
Bancshares common stock. In addition to solicitations by mail, directors,
officers and employees of Century Bancshares may solicit proxies personally or
by telephone without additional compensation.

                                  THE MERGER

   The following description summarizes the material terms of the merger
agreement. We urge you to read the agreement and plan of merger, a copy of
which is attached as Appendix A to this document and is incorporated by
reference into this document, and the form of plan of merger, a copy of which
is attached as Appendix B to this document and is incorporated by reference
into this document.

Structure of the Merger

   Pursuant to the terms of the merger agreement, Century Bancshares will merge
with and into Marshall & Ilsley. The separate legal existence of Century
Bancshares will cease. Marshall & Ilsley will continue to exist as the
surviving corporation. Marshall & Ilsley will exchange shares of its common
stock and up to approximately $22.82 million in cash for shares of Century
Bancshares common stock. Century Bancshares shareholders who do not perfect
their dissenters' rights under Minnesota law and who do not receive cash for
all of their shares will become Marshall & Ilsley shareholders, with their
rights governed by Wisconsin law and Marshall & Ilsley's restated articles of
incorporation and bylaws.

Background of the Merger

   In early 2001, the Board of Directors of Century Bancshares resolved to seek
out potential buyers and merger partners. Sheldon Wert, Chairman of the Board,
was authorized and directed to contact RBC Capital Markets concerning the
prospects for a merger or sale transaction involving Century Bancshares, Inc.

   In July of 2001, the dialogue between representatives of Century Bancshares
and RBC Capital Markets resulted in Century Bancshares engaging RBC Capital
Markets to develop an information package and presentation materials for use in
eliciting prospective potential buyers and merger partners for Century
Bancshares. While the information package was being prepared, Mark Furlong,
Chief Financial Officer of Marshall & Ilsley, solicited a meeting with Mr. Wert
to discuss a potential business combination.

   At the parties' meeting in August 2001, Mr. Wert advised Mr. Furlong that
Century Bancshares was soliciting indications of interest from several
potential suitors. Mr. Wert agreed to provide M&I with the information package
under development by Century Bancshares and RBC Capital Markets upon its
completion.

   Indications of interest were received from several parties, including M&I,
at the end of October 2001. Senior representatives of M&I and Century
Bancshares met in November 2001 to discuss terms of a potential merger
transaction. As a result of that meeting, the parties and M&I accepted the
responsibility for preparing a draft of a merger agreement. During the
remainder of November 2001, the parties and their legal counsel negotiated the
various provisions of the merger agreement.

   On December 3, 2001, the Board of Directors of Century Bancshares met with
representatives of RBC Capital Markets to review a presentation concerning the
fairness of the proposed merger transaction, from a financial point of view, to
the shareholders of Century Bancshares. Following the RBC Capital Markets
presentation, the Board of Directors unanimously approved the final draft of
the merger agreement and directed Mr. Wert to execute the merger agreement on
behalf of Century Bancshares. Mr. Wigdale executed the merger agreement on
behalf of M&I on the same day.

Management and Operations after the Merger

   After the merger is completed, the directors and officers of Marshall &
Ilsley who were in office prior to the effective time of the merger will
continue to serve as the directors and officers of Marshall & Ilsley for the
term for which they were elected, subject to Marshall & Ilsley's restated
articles of incorporation and bylaws and in accordance with applicable law.

                                      16



Merger Consideration

   The total consideration for the merger will be $58,819,946. An additional
$7,180,054 is expected to be paid to holder of options to acquire Century
Bancshares common stock. Unless you elect to receive cash for your shares of
Century Bancshares common stock as described below, at the effective time of
the merger, each share of issued and outstanding Century Bancshares common
stock will be converted to a fraction of a share of Marshall & Ilsley common
stock with a value of approximately $7.40. The number of Marshall & Ilsley
shares you receive will be equal to (i) approximately $7.40, divided by (ii)
the average of the average high and low sale price per share of Marshall &
Ilsley common stock on the NYSE for the 10 trading days ending on and including
the second trading day preceding the effective time of the merger, rounded to
the nearest one-hundred thousandth.

   For example, if you do not elect to receive cash in exchange for your shares
of Century Bancshares common stock, and if you hold 100 shares of Century
Bancshares common stock, then assuming the average trading price of Marshall &
Ilsley common stock is $60.00 per share, you will receive approximately 12
shares of Marshall & Ilsley common stock and $20.00 in cash in lieu of a
fractional share of Marshall & Ilsley common stock.

   The average trading price used to calculate the exchange ratio is likely to
be different from the closing price per share of Marshall & Ilsley common stock
at the time of merger. As a result, the value of the Marshall & Ilsley common
stock that you are entitled to receive may be different from $7.40.

   You may also elect to receive cash in exchange for your shares of Century
Bancshares common stock. If you make such an election then the cash amount you
will receive for each share of your Century Bancshares common stock will be an
amount equal to approximately $7.40. If you make such an election and if the
amount of cash that holders of shares of Century Bancshares common stock elect
to receive in exchange for their shares exceeds a total of approximately $22.82
million, the amount of cash that you will receive for each share will be
subject to a pro rata reduction, and you will receive a number of shares of
Marshall & Ilsley common stock with a value equal to the amount of that
reduction.

   A form of election has been included with this proxy statement/prospectus.
You may elect to receive cash for your shares of Century Bancshares common
stock by completing and signing the enclosed form of election and submitting it
to Continental Stock Transfer & Trust Company, our exchange agent, at 17
Battery Place, 8/th/ Floor, New York, New York, 10004, by the election
deadline, which is 5:00 p.m., Minneapolis time, on    , , 2002. If you have
made an election to receive cash for your shares, you may at any time change or
withdraw your election by written notice to the exchange agent prior to the
election deadline. If you do not submit a properly completed and signed form of
election to the exchange agent prior to the election deadline, then your shares
shall be converted into the right to receive Marshall & Ilsley common stock at
the effective time.

No Fractional Shares

   Only whole shares of Marshall & Ilsley common stock will be issued in
connection with the merger. In lieu of fractional shares, each holder of
Century Bancshares common stock otherwise entitled to a fractional share of
Marshall & Ilsley common stock will be paid, without interest, an amount of
cash equal to the amount of this fraction multiplied by the average trading
price of a share of Marshall & Ilsley common stock for the 10 trading days
ending on and including the second trading day preceding the merger. No
shareholder will be entitled to interest, dividends, voting rights or other
rights with respect to any fractional share.

Effective Time of the Merger

   Unless Century Bancshares and Marshall & Ilsley agree otherwise, the
effective time of the merger will be as soon as practicable after all
conditions contained in the merger agreement have been met or waived, including
the expiration of all applicable waiting periods. Century Bancshares and
Marshall & Ilsley each will have the right, but not the obligation, to
terminate the merger agreement if the effective time of the merger does not
occur on or before

                                      17



   June 30, 2002, unless the failure of the merger to occur by such date is due
to the failure of the party seeking such termination to comply with its
obligations under the merger agreement.

Exchange of Certificates

   As of the effective time of the merger, Marshall & Ilsley will deposit, or
cause to be deposited, from time to time, with the exchange agent, Continental
Stock Transfer & Trust Company, certificates representing the shares of
Marshall & Ilsley common stock and cash to be issued pursuant to the merger in
exchange for outstanding shares of Century Bancshares common stock. Continental
Stock Transfer & Trust Company will act as the exchange agent for the benefit
of the holders of certificates of Century Bancshares common stock.

   After the effective time of the merger, you will cease to have any rights as
a holder of Century Bancshares common stock, and your sole right will be your
right to receive the merger consideration, including cash in lieu of fractional
shares, if any, into which your shares of Century Bancshares common stock will
have been converted by virtue of the merger, or to perfect your dissenter's
rights if you have validly exercised and not withdrawn or lost such rights.

   As soon as practicable after the effective time of the merger, the exchange
agent will send to you a letter of transmittal and instructions for use in
submitting to the exchange agent certificates formerly representing shares of
your Century Bancshares common stock to be exchanged for certificates
representing shares of Marshall & Ilsley common stock and, to the extent
applicable, cash which you elected to receive for your shares of Century
Bancshares common stock and cash in lieu of fractional shares of Marshall &
Ilsley common stock, that you are entitled to receive as a result of the
merger. You will also receive instructions for handling share certificates
which have been lost, stolen or destroyed. You will not be entitled to receive
any dividends or other distributions which may be payable to holders of record
of Marshall & Ilsley common stock following the effective time of the merger
until you have surrendered and exchanged your Century Bancshares common stock
certificates, or, in the case of lost, stolen or destroyed share certificates,
such documentation as is reasonably required by Marshall & Ilsley. Any
dividends with a record date after the effective time of the merger payable on
Marshall & Ilsley common stock after the effective time of the merger will be
paid to the exchange agent and, upon receipt of the Century Bancshares common
stock certificates or, in the case of lost, stolen or destroyed share
certificates, such documentation as is required by Marshall & Ilsley, subject
to any applicable abandoned property, escheat or similar laws, the exchange
agent will forward to you the following as applicable:

 . certificates representing your shares of Marshall & Ilsley common stock;

 . cash, if any, which you elected to receive in exchange for your shares of
        Century Bancshares common stock;

 . dividends declared on your shares of Marshall & Ilsley common stock with a
            record date after the effective time of the merger, without
            interest; and

 . the cash value of any fractional shares, without interest.

   Please DO NOT return your Century Bancshares stock certificates with the
enclosed proxy card. You should not submit your Century Bancshares stock
certificates until you have received written instructions from the exchange
agent to do so.

   At the effective time of the merger, the stock transfer books of Century
Bancshares will be closed and no transfer of Century Bancshares common stock
will thereafter be made on Century Bancshares's stock transfer books. If a
certificate formerly representing Century Bancshares common stock is presented
to Century Bancshares or Marshall & Ilsley, it will be forwarded to the
exchange agent for cancellation and exchange for the merger consideration.

                                      18



Interests of Certain Persons

   In addition to being shareholders of Century Bancshares, certain members of
the management of Century Bancshares have interests in the proposed merger
transaction.

   In connection with the proposed merger transaction, each of the executive
officers and directors identified below entered into agreements with Century
Bancshares, pursuant to which all non-qualified stock options held by such
persons were cancelled in exchange for cash payments equal to $7.398 less the
applicable exercise price for each share covered under the cancelled option
agreements. The number of shares covered under cancelled option agreements and
the resulting gain realized by each of these persons is as follows:

   In December 2001, Century Bank entered into a Consulting and Noncompetition
Agreement (the "Consulting Agreement") with Sheldon Wert, Chairman of the Board
of Directors of Century Bancshares. The Consulting Agreement, which has a term
of three years commencing upon date of the Merger, provides Mr. Wert with
various benefits, including medical and dental insurance, office and
secretarial assistance, reimbursement of country club dues, use of an
automobile and the right to purchase certain assets (including office
furniture, an automobile and a life insurance policy) at their book value as
set forth on the books and records of Century Bank. In exchange for such
compensation, Mr. Wert has agreed to provide Century Bank with consulting
services as required throughout the term of the Consulting Agreement, to
refrain from competing with Century Bank and from soliciting its customers and
employees, and not to disclose to third parties any confidential information
possessed by Mr. Wert with respect to Century Bank or Century Bancshares.

   In October 2001, Century Bank entered into executive retention agreements
with each of Kim Culp, Kenneth Brooks and Leif Syverson. Each agreement
provides the executive with financial incentives to remain in the employ of
Century Bank at the time of, and following the Merger, as follows:

 . $50,000 payment to the executive on the date of the closing of the merger;

 . $100,000 payment to the executive on the six-month anniversary of the closing
           of the merger; and

 . $100,000 payment to the executive on the one-year anniversary of the closing
           of the merger;

   Assuming the executive is employed by Century Bank on the date of the
merger, the agreements obligate Century Bank to continue the executive's
employment for a two-year period thereafter. However, the executive's
employment may be terminated for "just cause" (as defined), in which event the
executive would not be entitled to receive any further incentive payments or
other employment compensation for the remainder of the two-year period.

Recommendation of the Century Bancshares Board of Directors and Reasons for the
Merger

   On December 3, 2001, the Century Bancshares board of directors unanimously
determined that the merger agreement and the transactions contemplated by the
merger agreement were advisable and fair to and in the best interests of
Century Bancshares and its shareholders. In reaching its decision to approve
the merger agreement and the transactions contemplated by the merger agreement,
the Century Bancshares board consulted with its financial advisor, RBC National
Markets, and its legal counsel, Maslon Edelman Borman & Brand, LLP, and with
senior management of Century Bank. The Century Bancshares board concluded that
the price per share being paid for the common stock of Century Bancshares and
other terms and conditions of the proposed merger transaction are favorable to
the shareholders of Century Bancshares and comparable to transactions similar
in size and nature that have recently occurred in Century Bancshares market.

Marshall & Ilsley's Reasons for the Merger

   In reaching its decision to approve the merger agreement, Marshall & Ilsley
considered a variety of factors, including the following:

 . Marshall & Ilsley's familiarity with and review of Century Bancshares's
           business, operations, management, markets, competitors, financial
           condition, earnings and prospects;
 . Century Bancshares's financial strength, stable credit quality and
          concentration in an attractive Midwestern metropolitan area;

 . The business, operations, financial condition, earnings and prospects of each
      of Marshall & Ilsley and Century Bancshares;

 . Century Bancshares's compatible risk philosophy, credit culture, shareholder
          focus and operating philosophy;

 . Marshall & Ilsley's belief that after the merger the combined company will be
           able to continue to generate high revenue growth rates;

 . The merger will allow Marshall & Ilsley to expand its operations in the
      Minneapolis, Minnesota area;

 . Century Bancshares's market is contiguous and similar to Marshall & Ilsley's
          Midwest markets;

 . The merger is intended to qualify as a transaction of a type that is
      generally tax-free for federal income tax purposes; and

 . The merger is expected to qualify as a purchase for accounting purposes.

   The foregoing discussion of the information and factors considered by
Marshall & Ilsley is not intended to be exhaustive but is believed to include
all material factors considered by Marshall & Ilsley. In reaching its
determination to enter into the merger agreement, Marshall & Ilsley did not
assign any relative or specific weights to the foregoing factors.

Material Federal Income Tax Consequences

   As a condition to the consummation of the merger, Century Bancshares will
receive from Maslon Edelman Borman & Brand, LLP, and Marshall & Ilsley will
receive from Godfrey & Kahn, S.C., an opinion that, for federal income tax
purposes, the merger will constitute a "reorganization" within the meaning of
Section 368(a) of the Internal Revenue Code.

                                      20



   The opinions will be based on factors, assumptions and representations set
forth in the opinions, including representations contained in certificates of
officers of Century Bancshares and Marshall & Ilsley. An opinion of counsel
represents only counsel's best legal judgment on the matters addressed in the
opinion, and has no binding effect on the Internal Revenue Service or any
court, and no assurance can be given that contrary positions may not be taken
by the Internal Revenue Service or a court considering the issues. Neither
Century Bancshares nor Marshall & Ilsley has requested or will request a ruling
from the Internal Revenue Service with regard to any of the federal income tax
consequences of the merger.

   As discussed below, the federal income tax consequences of the merger to a
Century Bancshares shareholder will depend on whether the shareholder exchanges
the Century Bancshares common stock for Marshall & Ilsley common stock, cash or
a combination thereof.

   Exchange Solely for Marshall & Ilsley Common Stock. If, pursuant to the
merger, a shareholder exchanges all of the shares of Century Bancshares common
stock actually owned by such shareholder solely for shares of Marshall & Ilsley
common stock, such shareholder will not recognize any gain or loss except cash
received in lieu of a fractional share of Marshall & Ilsley common stock (as
discussed below). The aggregate adjusted tax basis of the shares of Marshall &
Ilsley common stock received in the exchange will be equal to the aggregate
adjusted tax basis of the shares of Century Bancshares common stock surrendered
therefore (adjusted for fractional shares), and the holding period of such
Marshall & Ilsley common stock will include the period during which such shares
of Century Bancshares common stock were held.

   Cash Received in Lieu of a Fractional Share. Cash received by a Century
Bancshares common stockholder in lieu of a fractional share of Marshall &
Ilsley common stock will be treated as received in exchange for such fractional
share, and gain or loss will be recognized, measured by the difference between
the amount of cash received and the portion of the basis of the share of
Century Bancshares common stock allocable to such fractional interest. Such
gain or loss should be long-term capital gain or loss if the holding period for
such share of Century Bancshares common stock was more than one year.

   Exchange Solely for Cash. In general, if, pursuant to the merger, a
shareholder exchanges all of the shares of Century Bancshares common stock
actually owned by such shareholder solely for cash, such shareholder will
generally recognize capital gain or loss equal to the difference between the
amount of cash received and its adjusted tax basis in the shares of Century
Bancshares common stock surrendered. The gain or loss will be long-term capital
gain or loss if the shareholder's holding period with respect to the shares of
Century Bancshares common stock surrendered is more than one year. If, however,
any such shareholder constructively owns shares of Century Bancshares common
stock that are exchanged for shares of Marshall & Ilsley common stock in the
merger or owns shares of Marshall & Ilsley common stock actually or
constructively after the merger, the consequences to such shareholder may be
similar to the consequences described below. In addition, the amount of
consideration, if any, treated as a dividend may not be limited to the amount
of such shareholder's gain.

   Exchange for Marshall & Ilsley Common Stock and Cash. If, pursuant to the
merger, a shareholder exchanges all of the shares of Century Bancshares common
stock actually owned by it for a combination of Marshall & Ilsley common stock
and cash, the shareholder will generally recognize gain, but not loss, with
respect to Century Bancshares common stock surrendered in an amount equal to
the lesser of (i) the amount of gain realized ( i.e., the excess of the sum of
the amount of cash and the fair market value of Marshall & Ilsley common stock
received over the adjusted tax basis of Century Bancshares Common Stock) and
(ii) the amount of cash received. For this purpose, gain or loss must be
calculated separately for each identifiable block of shares surrendered in the
exchange, and a loss realized on one block of shares may not be used to offset
a gain realized on another block of shares. Any recognized gain will generally
be long-tem capital gain if the shareholder's holding period with respect to
the stock is more than one year. If, however, the cash received has the effect
of the distribution of a dividend, the gain would be treated as a dividend to
the extent of the shareholder's ratable share of Century Bancshares's
accumulated earnings and profits.


                                      21



   The aggregate tax basis of Marshall & Ilsley common stock received by a
shareholder that exchanges its shares of Century Bancshares common stock for a
combination of Marshall & Ilsley common stock and cash pursuant to the merger
will be the same as the aggregate adjusted tax basis of the shares of Century
Bancshares common stock surrendered therefor, decreased by the cash received
and increased by any recognized gain (whether capital gain or ordinary income).
The holding period of such Marshall & Ilsley common stock will include the
holding period of the shares of Century Bancshares common stock surrendered
therefor.

   Possible Treatment of Cash as a Dividend. In general, the determination of
whether the gain recognized in the exchange will be treated as capital gain or
has the effect of a distribution of a dividend depends upon whether, and to
what extent, the exchange reduces the shareholder's deemed percentage stock
ownership of Marshall & Ilsley. For purposes of this determination, the
shareholder is treated as if such shareholder first exchanged all of such
shareholder's shares of Century Bancshares common stock solely for Marshall &
Ilsley common stock and then Marshall & Ilsley immediately redeemed a portion
of such Marshall & Ilsley common stock in exchange for the cash the shareholder
actually received. The gain recognized in the exchange followed by a deemed
redemption will be treated as capital gain if the deemed redemption is (i)
"substantially disproportionate" with respect to the shareholder, or (ii) not
essentially equivalent to a dividend.

   The deemed redemption, generally, will be "substantially disproportionate"
with respect to a shareholder if the percentage described in (ii) below is less
than 80% of the percentage described in (i) below. Whether the deemed
redemption is "not essentially equivalent to a dividend" with respect to a
shareholder will depend upon the shareholder's particular circumstances. At a
minimum, however, in order for the deemed redemption to be "not essentially
equivalent to a dividend," the deemed redemption must result in a "meaningful
reduction" in the shareholder's actual and constructive percentage stock
ownership of Marshall & Ilsley. In general, that determination requires a
comparison of (i) the percentage of the outstanding stock of Marshall & Ilsley
the shareholder is deemed actually and constructively to own immediately before
the deemed redemption and (ii) the percentage of the outstanding stock of
Marshall & Ilsley the shareholder actually and constructively owns immediately
after the deemed redemption. In applying the foregoing tests, a shareholder is
deemed to own stock owned and, in some cases, constructively owned, by certain
family members, by certain estates and trusts of which the shareholder is a
beneficiary, and by certain affiliated entities. As these rules are complex,
each shareholder that may be subject to these rules should consult such
shareholder's tax advisor. The Service has ruled that a relatively minor
reduction in the percentage stock ownership of a minority shareholder in a
publicly held corporation whose relative stock interest is minimal and who
exercises no control with respect to corporate affairs is a "meaningful
reduction."

   The foregoing discussion is intended only as a summary of the material
federal income tax consequences of the merger. The foregoing discussion does
not address the tax consequences that may be relevant to particular taxpayers
in light of their personal circumstances or to taxpayers subject to special
treatment under the Internal Revenue Code.

   No information is provided in this document with respect to the tax
consequences, if any, of the merger under applicable state, local, foreign and
other tax laws. The foregoing discussion is based upon the provisions of the
Internal Revenue Code, applicable Treasury regulations thereunder, Internal
Revenue Service rulings, and judicial decisions as in effect as of the date of
this document. We cannot assure you that future legislative, administrative or
judicial changes or interpretations will not affect the accuracy of the
statements or conclusions set forth in this document. Any such change could
apply retroactively and could affect the accuracy of such discussion.

You are urged to consult your own tax advisor as to the specific tax
consequences to you of the merger, including the application of federal, state,
local, foreign and other tax laws.

Regulatory Approvals

   The merger is subject to prior approval by the Federal Reserve Board under
Section 3 of the Bank Holding Company Act of 1956, or BHCA. The BHCA requires
the Federal Reserve Board, when considering a transaction such as this merger,
to take into consideration the financial and managerial resources, including
the competence, experience and integrity of the officers, directors and
principal shareholders, and future prospects of the institutions and the
convenience and needs of the communities to be served. In addition, under the
Community Reinvestment Act of 1977, as amended, the Federal Reserve Board must
take into account the record of performance of the acquiring institution in
meeting the credit needs of the entire community, including low-and
moderate-income neighborhoods, served by the institution.

   The BHCA also prohibits the Federal Reserve Board from approving a merger if
it would result in a monopoly or be in furtherance of any combination or
conspiracy to monopolize or attempt to monopolize the business of banking in
any part of the United States, or if its effect in any section of the country
would be substantially to lessen competition or to tend to create a monopoly,
or if it would in any other manner result in a restraint of trade, unless the
Federal Reserve Board finds that the anticompetitive effects of the merger are
clearly outweighed in the public interest by the probable effect of the
transaction in meeting the convenience and needs of the communities to be
served.

   Pursuant to the BHCA, the merger may not be consummated until 30 days after
Federal Reserve Board approval, during which time the United States Department
of Justice may challenge the merger on antitrust grounds. The commencement of
an antitrust action would stay the effectiveness of the Federal Reserve Board's
approval unless a court specifically ordered otherwise. With the approval of
the Federal Reserve Board and the concurrence of the Department of Justice, the
waiting period may be reduced to not less than 15 days. Marshall & Ilsley and
Century Bancshares believe that the merger does not raise substantial antitrust
or other significant regulatory concerns and that they will be able to obtain
all requisite regulatory approvals on a timely basis without the imposition of
any condition that would have a material adverse effect on Marshall & Ilsley
and Century Bancshares.

   Other Requisite Approvals and Consents.  Approvals or notices are also
required from or to the New York Stock Exchange and other self-regulatory
organizations and may be required from or to certain other regulatory agencies.

   Status of Regulatory Approvals.  Marshall & Ilsley filed an application with
the Federal Reserve Board for approval of the merger on December 31, 2001.

   The merger cannot proceed in the absence of the requisite regulatory
approvals. We do not know if or when all of these regulatory approvals will be
obtained. Also, these approvals may contain a condition, restriction or
requirement that causes these approvals to fail to satisfy the conditions for
the merger.

Accounting Treatment

   Marshall & Ilsley expects to account for the merger for accounting and
financial reporting purposes as a "purchase," as that term is used under
accounting principles generally accepted in the United States. Under purchase
accounting, the assets and liabilities of Century Bancshares as of the
effective time will be recorded at their fair values and added to those of
Marshall & Ilsley. Any excess of the value of Marshall & Ilsley common stock
issued for Century Bancshares common stock over the fair value of Century
Bancshares's identifiable net assets will be recorded as goodwill. Financial
statements of Marshall & Ilsley issued after the effective time will reflect
these values and will not be restated retroactively to reflect the historical
financial position or results of operations of Century Bancshares.

   The Financial Accounting Standards Board has issued several statements of
Financial Accounting Standards that eliminate the pooling-of-interests method
of accounting for business combinations and require that goodwill and certain
intangible assets not be amortized. Instead, these assets will be reviewed for
impairment annually with any

                                      23



related losses recognized in earnings when incurred. These statements are
effective for Marshall & Ilsley for business combinations completed after July
1, 2001 and will be effective for existing goodwill and intangible assets on
December 31, 2001.

Resales of Marshall & Ilsley Common Stock

   The shares of Marshall & Ilsley common stock to be issued in the merger will
be freely transferable under the Securities Act of 1933, as amended. However,
this will not be the case for shares issued to any shareholder who may be
deemed to be an "affiliate" of Century Bancshares for purposes of Rule 145
under the Securities Act as of the date of the special meeting. "Affiliates"
generally include directors, certain executive officers, and beneficial owners
of 10 percent or more of any class of capital stock. These affiliates may not
sell their shares of Marshall & Ilsley common stock acquired in the merger
except pursuant to an effective registration statement under the securities
laws or other applicable securities law exemptions from the registration
requirements of the securities laws.

   This proxy statement/prospectus does not cover resales of Marshall & Ilsley
common stock received by any person who may be deemed to be an affiliate of
Century Bancshares. Century Bancshares has agreed in the merger agreement to
use its reasonable efforts to cause each person who may be deemed to be an
affiliate of Century Bancshares to execute and deliver to Marshall & Ilsley an
affiliate agreement. As provided for in these agreements, Century Bancshares's
affiliates agree not to offer to sell, transfer or otherwise dispose of any of
the shares of Marshall & Ilsley common stock distributed to them pursuant to
the merger except in compliance with Rule 145, or in a transaction that is
otherwise exempt from the registration requirements of, or in an offering which
is registered under, the Securities Act. Marshall & Ilsley may place
restrictive legends on certificates representing Marshall & Ilsley common stock
issued to all persons who are deemed to be affiliates of Century Bancshares
under Rule 145.

Dissenters' Rights

   Shareholders of Century Bancshares are entitled to dissenters' rights in
connection with the merger. The procedures for preserving and exercising
dissenters' rights are set forth in the provisions of Sections 302A.471 and
302A.473 of the Minnesota Business Corporation Act. The following is a
description of those provisions. It is not complete and is qualified by
reference to the actual provisions, copies of which are included in Appendix C
to this document. Appendix C is incorporated by reference into this document.

   Notice of Dissenters' Rights. Century Bancshares is required to notify its
shareholders of their dissenters' rights and to provide them with a copy of
Sections 302A.471 and 302A.473 of the Minnesota Business Corporation Act. This
document, including the notice of special meeting of Century Bancshares
shareholders, constitutes the required notice to shareholders of Century
Bancshares. A copy of Sections 302A.471 and 302A.473 of the Minnesota Business
Corporation Act is included in Appendix C to this document.

   Preserving Dissenters' Rights. To preserve your dissenters' rights, you must
do each of the following:

 . deliver to Century Bancshares, before the vote is taken at the special
          meeting of shareholders, written notice of your intent to demand the
          fair value of your shares if the merger is completed; and

 . not vote your shares of Century Bancshares common stock in favor of the
      merger agreement and the merger.

   If you sign and return your proxy without voting instructions, and do not
revoke the proxy, the proxy will be voted for the merger and merger agreement
and you will have waived your dissenters' rights.

   Beneficial Owners. Beneficial owners of shares who desire to exercise
statutory dissenters' rights must obtain and submit to Century Bancshares the
registered shareholder's written consent at or before the time the notice of
intent to demand fair value is due. A shareholder may not assert dissenters'
rights with respect to less

                                      24



than all of the shares registered in the shareholder's name, unless the
shareholder dissents with respect to all shares beneficially owned by another
person and discloses the name and address of such other person.

   Notice of Merger Approval. If the merger and merger agreement are approved
by Century Bancshares's shareholders, Century Bancshares must deliver a written
dissenters' notice to all shareholders who preserved their dissenters' rights.
The notice must do all of the following:

 . state where and by what date the payment demand must be sent and where and by
        what date certificates for certificated shares must be deposited;

 . inform holders of uncertificated shares to what extent transfer of the shares
         will be restricted after the payment demand is received;

 . supply a form for demanding payment and for certifying the date on which the
         shareholder, or the beneficial owner on whose behalf the shareholder
         dissents, acquired the shares or an interest in the shares; and

 . be accompanied by a copy of Sections 302A.471 and 302A.473 of the Minnesota
     Business Corporation Act and a brief description of the procedures to be
     followed under those Sections.

   Duty to Demand Payment. A shareholder who is sent a dissenters' notice must
demand payment and deposit the shareholder's certificates or comply with any
restrictions on transfer of uncertificated shares within 30 days after the
dissenter's notice is given. Under Minnesota law, notice by mail is given when
deposited in the mail. A shareholder who so demands payment and so deposits the
shareholder's certificates or so complies with any restrictions on transfer of
uncertificated shares retains all other rights of a shareholder until these
rights are canceled or modified by the merger. A shareholder who does not so
demand payment or who does not so deposit the shareholder's certificate or so
comply with any restrictions on transfer of uncertificated shares is only
entitled to receive the merger consideration for the shareholder's shares.

   Share Restrictions. Century Bancshares may restrict the transfer of
uncertificated shares from the date the demand for their payment is received
until the merger is completed or until the restrictions are released because
the merger is not completed.

   Payment. Except as to after-acquired shares as discussed below, at the time
the merger is completed, or upon receipt of a payment demand, whichever occurs
later, Century Bancshares must pay to each dissenter who demanded payment in
the manner required the amount Century Bancshares estimates to be the fair
value of the dissenter's shares immediately before the effective time of the
merger plus interest accrued from fifth day after the date of the merger. The
payment must be accompanied by all of the following:

 . Century Bancshares's balance sheet and income statement as of and for a
          fiscal year ended not more than 16 months before the effective time
          of the merger, and the latest available interim financial statements,
          if any;

 . a statement of Century Bancshares's estimate of the fair value of the shares
     and a brief description of the method used to reach the estimate;

 . a description of the procedure the dissenter must follow to demand
     supplemental payment if the dissenter is dissatisfied with Century
     Bancshares's payment offer; and

 . a copy of Sections 302A.471 and 302A.473 of the Minnesota Business
     Corporation Act and a brief description of the procedure to be followed in
     demanding supplemental payment.

   Failure of Century Bancshares to Remit Payment. If Century Bancshares does
not remit payment within 60 days after the deposit of share certificates or the
imposition of transfer restrictions on uncertificated shares, Century
Bancshares must return the deposited certificates and release the transfer
restrictions on uncertificated shares. Century Bancshares may again give notice
under the statute and require deposit or restrict transfer at a later time.

                                      25



   After Acquired Shares. Century Bancshares may elect to withhold payment to a
dissenting shareholder if the dissenter, or person on whose behalf such
dissenter acts, was not the beneficial owner of the shares on the date of the
first announcement to the public of the terms of the merger. The terms of the
merger were first announced to the public on December 4, 2001. If Century
Bancshares elects to withhold payment and the dissenter has complied with the
terms of the statute, it must forward the materials described above to the
dissenter along with a statement of the reason for withholding the payment and
an offer to pay the dissenter the amount listed in the materials if the
dissenter agrees to accept that amount in full satisfaction.

   Procedure if Dissatisfied with Payment or Offer. A dissenter may notify
Century Bancshares in writing of the dissenter's own estimate of the fair value
of the dissenter's shares and the amount of interest due, and demand payment of
the dissenter's estimate, less any payment made by Century Bancshares.

   A dissenter waives the dissenter's rights to demand payment, and is entitled
only to the amount remitted or offered, unless the dissenter notifies Century
Bancshares of the dissenter's estimate and demand in writing within 30 days
after Century Bancshares mailed payment, or in the case of after-acquired
shares offered payment, for the dissenter's shares.

   Court Action. Within 60 days after receiving the payment demand, Century
Bancshares will either petition the court to determine the fair value of the
shares and accrued interest or pay to the dissenter the amount demanded or
agreed to by the dissenter after discussion with the corporation. Century
Bancshares must make all dissenters, whether or not residents of Minnesota,
whose demands remain unsettled, parties to the proceeding and must serve them
all with a copy of the petition. The court may appoint one or more appraisers
to receive evidence and recommend decision on the question of fair value. Each
dissenter made a party to the proceeding is entitled to a judgment for the
amount, if any, by which the court finds the fair value of the dissenter's
shares, plus interest, exceeds the amount paid by Century Bancshares. However,
a dissenter is not liable to Century Bancshares for the amount, if any, by
which the payments remitted by Century Bancshares exceed the fair value of the
dissenter's shares determined by the court, plus interest.

   Court Costs and Counsel Fees. The court will determine all costs of the
appraisal proceeding, including the reasonable compensation and expenses of
appraisers appointed by the court. The court will assess the costs against
Century Bancshares, except that the court may assess costs against all or some
of the dissenters to the extent the court finds the dissenters acted
arbitrarily, vexatiously, or not in good faith in demanding payment. Also, the
court may assess the fees and expenses of counsel and experts for the
respective parties as follows:

 . against Century Bancshares and in favor of any or all dissenters if the court
          finds Century Bancshares did not substantially comply with the
          requirements of Section 302A.473 of the Minnesota Business
          Corporation Act; or

 . against either Century Bancshares or a dissenter, in favor of the other
          party, if the court finds that the
     party against whom the fees and expenses are assessed acted arbitrarily,
     vexatiously, or not in good faith in bringing the proceeding.

   The court has the discretion to award fees and expenses to an attorney for
the dissenters out of the amount awarded to the dissenters, if any.

   No Other Rights. A shareholder of Century Bancshares has no right at law or
equity to set aside the approval of the merger agreement or the consummation of
the merger, except if such approval or consummation is fraudulent with respect
to the shareholder or to Century Bancshares.

   The merger and the merger agreement will be approved if the holders of a
majority of the shares of Century Bancshares common stock outstanding on the
record date vote in favor of the merger and merger agreement. The

agreed that, without the prior written consent of Marshall & Ilsley, it and its
subsidiaries will not, among other things:

   . except as required by applicable law or to maintain qualification under

     $300,000 in aggregate if the merger has not become effective on or prior
     to April 19, 2002;

No Solicitation of Transactions

   Century Bancshares agreed to immediately cease any existing discussions or
negotiations relating to a competing proposal, not to solicit any competing
proposals and to promptly inform Marshall & Ilsley if any competing proposal is
made.

   For purposes of the merger agreement, we agreed that the term "competing
proposal" would mean, with respect to Century Bancshares, any inquiry, proposal
or offer from any person relating to:

   . any direct or indirect acquisition or purchase of a business that
     constitutes 15 percent or more of the net revenues, net income or the
     assets of Century Bancshares and its subsidiaries taken as a whole;

   . any direct or indirect acquisition or purchase of 15 percent or more of
     any class of equity securities of Century Bancshares or any of its
     subsidiaries;

   . any tender offer or exchange offer that if consummated would result in any
     person beneficially owning 15 percent or more of any class of equity
     securities of Century Bancshares or any of its subsidiaries; or

                                      29



   . any merger, consolidation, business combination, recapitalization,
     liquidation, dissolution or similar transaction involving Century
     Bancshares or any of its subsidiaries, other than the transactions
     contemplated by the merger agreement.

   For purposes of the merger agreement, we agreed that the term "superior
competing transaction" would mean any proposal made by a third party to
acquire, directly or indirectly, more than 50 percent of the combined voting
power of the shares of Century Bancshares common stock then outstanding or all
or substantially all of the assets of Century Bancshares and its subsidiaries,
taken as a whole, on terms which the board of directors of Century Bancshares
determines in its good faith judgment, taking into consideration the opinion of
a financial advisor of nationally recognized reputation, to be more favorable
to its shareholders than the merger and for which financing, to the extent
required, is then committed or, in the good faith and judgment of the board of
directors of Century Bancshares, is reasonably capable of being obtained by
such third party.

   Marshall & Ilsley and Century Bancshares have also agreed that the
limitations discussed above would not prohibit Century Bancshares's board of
directors, prior to approval of this merger and the merger agreement by the
shareholders of Century Bancshares, from entering into discussions or
negotiations relating to an unsolicited superior competing transaction. Prior
to entering into such discussions or negotiations, however, Century
Bancshares's board of directors must have determined in good faith and after
consultation with and taking into consideration the advice of counsel that such
action is required to fulfill its fiduciary duties to Century Bancshares's
shareholders. In addition, Century Bancshares must provide prior written notice
to Marshall & Ilsley that it is entering into such discussions or negotiations
and receive a confidentiality agreement from the person proposing the superior
competing transaction. Century Bancshares has also agreed to keep Marshall &
Ilsley informed of the status and details of such discussions or negotiations.

Employee Benefit Matters

   Marshall & Ilsley has agreed that it will give employees of Century
Bancshares who become employees of Marshall & Ilsley, whom we refer to as
transferred employees, full credit for their prior service with Century
Bancshares for purposes of eligibility and vesting under retirement plans in
which the transferred employees may be eligible to participate and for all
purposes under any welfare benefit plans, "cafeteria" plans, vacation plans and
similar arrangements maintained by Marshall & Ilsley. However, Marshall &
Ilsley will not give prior service credit in connection with the Marshall &
Ilsley retiree health plan.

   Marshall & Ilsley has also agreed to waive all preexisting conditions and
waiting periods with respect to participation and coverage requirements
applicable to transferred employees under any welfare benefit plans maintained
by Marshall & Ilsley in which transferred employees may be eligible to
participate. Marshall & Ilsley is not required to waive limitations or waiting
periods that are currently in effect and that have not been satisfied as of the
effective time of the merger under any welfare plan maintained for the
transferred employees prior to the effective time of the merger.

   Transferred employees will be integrated into Marshall & Ilsley's welfare
benefit plans at a time determined on a plan-by-plan basis by Marshall &
Ilsley, but no later than January 1, 2003. Century Bancshares's respective
plans will remain in effect until each integration date. Century Bancshares's
401(k) plan will be frozen as of the effective time of the merger and all
accounts in the plan will be fully vested at that time. Transferred employees
who are eligible to participate in Marshall & Ilsley's qualified retirement

                                                               defined in the statute, for the shares it acquires in
                                                               the business combination; or

                                      39



  from the prohibition on business combinations.

     The business combination statutes do not apply
  to the merger, because the merger is not a business
  combination with an interested stockholder within the
  meaning of the business combination statutes.

     Fair price statute. Wisconsin corporate law
  requires that business combinations between some
  Wisconsin corporations, including Marshall & Ilsley,
  and a person designated as a significant shareholder
  must be approved by 80 percent of all of the
  corporation's shareholders and two-thirds of all of the
  corporation's shareholders other than the significant
  shareholder. This requirement does not apply if the
  corporation's shareholders receive a fair price, as
  defined in the statute, for their shares from the
  significant shareholder in the business combination. A
  significant shareholder is a person who owns 10
  percent or more of the corporation's outstanding
  shares or who is an affiliate of the corporation and
  owned at least 10 percent of the corporation's
  outstanding shares at any time within the prior two-
  year period.

     The fair price statutes do not apply to the
  merger, because the merger is not a business
  combination with a significant shareholder within the
  meaning of the fair price statutes.

     Control share statute. Under Wisconsin
  corporate law, if a person holds more than 20 percent
  of the outstanding shares of some Wisconsin
  corporations, including Marshall & Ilsley, then the
  voting power of the shares held by that person in
  excess of 20 percent of the corporation's outstanding
  shares is reduced to 10 percent of the voting power
  the excess shares would otherwise have had. The full
  voting power of the excess shares may be restored by
  a vote of a majority of the corporation's shares. The
  person seeking restoration of full voting power may
  vote on this resolution.

     In addition to any other approvals required by
  law and by the articles of incorporation and bylaws,
  Marshall & Ilsley's articles of incorporation require
  that business combinations between Marshall & Ilsley
  and an interested stockholder be approved by:

  . the holders of 80 percent of Marshall & Ilsley's
    shares; or

  . the holders of two-thirds of Marshall & Ilsley's
    shares, other than the interested stockholder.


                                      40



              This requirement does not apply if business
           combination with an interested stockholder is
           approved by a majority of disinterested directors or
           the shareholders receive a fair price, as defined in the
           articles of incorporation, for their shares and certain
           other conditions are satisfied.

              Business combinations under Marshall &
           Ilsley's articles of incorporation generally include
           mergers, consolidations, sales of $25,000,000 or
           more in assets, the issuance or transfer of
           $25,000,000 or more in securities, liquidations,
           dissolutions, and reclassifications, recapitalizations
           and other transactions that have the effect of
           increasing the proportionate ownership interest of an
           interested stockholder. An interested stockholder is a
           person who owns at least 10 percent of Marshall &
           Ilsley's shares or who is an affiliate or associate of
           Marshall & Ilsley and owned at least 10 percent of
           Marshall & Ilsley's shares at any time within the
           prior two-year period. A disinterested director means
           a director who is not affiliated with the interested
           stockholder and who was either a director before the
           person became an interested stockholder or was
           elected or recommended for election by a majority of
           disinterested directors.

                         AGREEMENT AND PLAN OF MERGER

   AGREEMENT AND PLAN OF MERGER, dated as of December 3, 2001 (the
"Agreement"), between Century Bancshares, Inc., a Minnesota corporation (the
"Seller") and Marshall & Ilsley Corporation, a Wisconsin corporation (the
"Company").

   WHEREAS, the Boards of Directors of the Company and the Seller have each
determined that it is fair to and in the best interests of their respective
shareholders for the Seller to merge with and into the Company (the "Merger")
upon the terms and subject to the conditions set forth herein and in accordance
with the Minnesota Business Corporation Act (the "MBCA") and the Wisconsin
Business Corporation Law (the "WBCL");

   WHEREAS, the respective Boards of Directors of the Company and the Seller
have each approved the Merger of the Seller with and into the Company, upon the
terms and subject to the conditions set forth herein, and adopted and approved
this Agreement and the Plan of Merger (as hereafter defined);

   WHEREAS, subsequent to the approval of this Agreement and the Plan of Merger
by Seller's Board of Directors and concurrently with the execution of this
Agreement and as a condition and an inducement to the willingness of the
Company to enter into this Agreement, the Company and certain shareholders of
the Seller have entered into an agreement pursuant to which each such
shareholder has agreed to vote his or her shares of Seller Common Stock in
favor of the Merger;

   WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization under the provisions of Section 368 of the
Internal Revenue Code of 1986, as amended (the "Code"), and this Agreement
shall constitute the plan of reorganization;

   WHEREAS, for financial accounting purposes it is intended that the Merger
shall be accounted for as a purchase.

   NOW, THEREFORE, in consideration of the foregoing premises and the
representations, warranties and agreements contained herein, and subject to the
terms and conditions set forth herein, the parties hereto hereby agree as
follows:

                             ARTICLE I--THE MERGER

   SECTION 1.1 The Merger. Upon the terms and subject to the conditions set
forth in this Agreement, and in accordance with the MBCA, the WBCL and the Plan
of Merger attached hereto as Exhibit 1.1 (the "Plan of Merger"), at the
Effective Time (as defined in Section 1.2) Seller shall be merged with and into
the Company. As a result of the Merger, the separate corporate existence of
Seller shall cease and the Company shall continue as the surviving corporation
of the Merger (the "Surviving Corporation").

   SECTION 1.2 Effective Time. As promptly as practicable after the
satisfaction or, if permissible, waiver of the conditions set forth in Article
VII, the parties hereto shall cause the Merger to be consummated by filing
articles of merger (the "Articles of Merger") with the Secretary of State of
the State of Minnesota (the "Minnesota Secretary of State") and the Department
of Financial Institutions of the State of Wisconsin (the "DFI"), in such form
as required by, and executed in accordance with the relevant provisions of, the
MBCA and the WBCL (the date and time of the later of such filing with the
Minnesota Secretary of State or the DFI is referred to herein as the "Effective
Time").

   SECTION 1.3  Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in this Agreement and the applicable provisions of
the MBCA and the WBCL. Without limiting the generality of the foregoing, and
subject thereto, at the Effective Time, except as otherwise provided herein,
all the property, rights, privileges, immunities, powers and franchises of the
Company and the Seller shall vest in the Surviving

                                      A-1



Corporation, and all debts, liabilities and duties of the Company and the
Seller shall become the debts, liabilities and duties of the Surviving
Corporation.

   SECTION 1.4 Articles of Incorporation; By-Laws. At the Effective Time, the
Articles of Incorporation, as amended, of the Company (the "Company Articles")
and the By-Laws, as amended, of the Company (the "Company By-Laws"), as in
effect immediately prior to the Effective Time, shall be the Articles of
Incorporation and the By-Laws of the Surviving Corporation.

   SECTION 1.5 Directors and Officers. At the Effective Time, the directors of
the Company immediately prior to the Effective Time shall be the initial
directors of the Surviving Corporation, each to hold office in accordance with
the Articles of Incorporation and By-Laws of the Surviving Corporation and to
be assigned to the class previously assigned. At the Effective Time, the
officers of the Company immediately prior to the Effective Time, shall be the
initial officers of the Surviving Corporation, in each case until their
respective successors are duly elected or appointed.

   SECTION 1.6 Merger Consideration

   (a) The aggregate dollar value of the merger consideration shall be
$66,000,000 minus the Option Payment Amount as defined in (c) below (the
"Merger Consideration"). The Merger Consideration shall consist of shares of
common stock, par value $1.00 per share, of the Company ("Company Common
Stock"); provided, however, that up to $30,000,000 minus the Option Payment
Amount (the "Cash Amount") of the Merger Consideration may be payable in cash
at the election of holders of the Seller Common Stock (as hereinafter defined).
For purposes of valuing the Company Common Stock as part of the Merger
Consideration, one share of Company Common Stock will be deemed to have a value
equal to the average of the average high and low sale price per share of
Company Common Stock on the New York Stock Exchange (the "NYSE") as reported in
the Midwest Edition of The Wall Street Journal for the ten (10) consecutive
trading days ending on and including the second trading day preceding the
Effective Time (the "Average Trading Price"). The Company agrees that all of
the Company's purchases of Company Common Stock shall be in accordance with
Regulation M of the Exchange Act.

   (b) The "Per Share Merger Consideration" shall be an amount equal to the
aggregate value of the Merger Consideration divided by the total number of
shares of Series A common stock, $.01 par value, and Series B common stock,
$.01 par value, of the Seller (collectively, the "Seller Common Stock") issued
and outstanding immediately prior to the Effective Time (the "Outstanding
Seller Common Stock").

   (c) The "Option Payment Amount" shall be an amount equal to (A) the number
of shares of Seller Common Stock subject to options immediately prior to the
Effective Time (such options are referred to collectively as the "Outstanding
Options") multiplied by $7.398 (such product to be rounded to the nearest whole
cent), minus (B) the aggregate exercise price of all Outstanding Options.

   SECTION 1.7 Conversion of Securities; Dissenting Shares. Subject to Section
1.7(h) regarding fractional shares, at the Effective Time, by virtue of the
Merger and without action on the part of the Company, the Seller or the holders
of the Seller's securities:

   (a) Each share of Seller Common Stock issued and outstanding immediately
prior to the Effective Time, other than Shares owned by the Company or any
direct or indirect wholly owned Company Subsidiary or Seller Subsidiary for its
own account (all such shares of Seller Common Stock issued and outstanding
immediately prior to the Effective Time being referred to herein as the
"Shares") and other than Dissenting Shares (as defined in Section 1.7(j)),
shall be converted into the right to receive a number of shares of Company
Common Stock, determined by dividing the Per Share Merger Consideration by the
Average Trading Price and rounding the result to the nearest one thousandth of
a share (the "Stock Consideration"); provided, however, that, subject to the
election and allocation procedures set forth in this Section 1.7, each holder
of such Shares will be entitled,

                                      A-2



with respect to the Merger Consideration to be received for each such Share
held by the holder, to elect to receive cash from the Company, without interest
(a "Cash Election"), in an amount equal to the Per Share Merger Consideration
(the "Cash Consideration").

   (b) The number of Shares which may be converted into the right to receive
the Cash Consideration in the Merger shall be no more than (i) the Cash Amount
divided by the Per Share Merger Consideration (rounded down to the nearest
whole number) minus (ii) the total number of Dissenting Shares, if any (the
"Cash Election Number").

   (c) If the aggregate number of Shares covered by Cash Elections (the "Cash
Election Shares") exceeds the Cash Election Number, each Cash Election Share
shall be converted, at the Effective Time, into the right to receive (i) an
amount in cash, without interest, equal to the product of (x) the Per Share
Merger Consideration and (y) a fraction (the "Cash Fraction"), the numerator of
which shall be the Cash Election Number and the denominator of which shall be
the total number of Cash Election Shares, and (ii) a number of shares of
Company Common Stock equal to the product of (x) the Stock Consideration and
(y) a fraction equal to one minus the Cash Fraction.

   (d) In the event that Section 1.7(c) above is inapplicable, all Cash
Election Shares shall be converted, at the Effective Time, into the right to
receive the Cash Consideration and all other Shares, other than Dissenting
Shares, shall be converted, at the Effective Time, into the right to receive
the Stock Consideration.

   (e) All Cash Elections shall be made on a form designed for that purpose and
mutually acceptable to the Company and Seller (a "Form of Election") and mailed
to holders of record of Shares as of the record date for the Seller
Shareholders' Meeting (as defined below) or such other date as the Company and
the Seller shall mutually agree (the "Election Form Record Date"). The Company
and the Seller shall make available one or more Election Forms as may be
reasonably requested by all persons who become holders of record of Shares
between the Election Form Record Date and the Election Deadline (as defined
below). Elections shall be made by submitting to the Exchange Agent (as defined
below) a duly completed Form of Election. To be effective, a Form of Election
must be properly completed, signed and submitted to the Exchange Agent in
accordance with Section 1.7(f). The Company will have the discretion, which it
may delegate in whole or in part to the Exchange Agent, to reasonably determine
whether Forms of Election have been properly completed, signed and submitted or
revoked and to disregard immaterial defects in Forms of Election. The decision
of the Company (or the Exchange Agent) shall be conclusive and binding. Neither
the Company nor the Exchange Agent will be under any obligation to notify any
person of any defect in a Form of Election submitted to the Exchange Agent. The
Exchange Agent shall also make all computations contemplated by this Section
1.7 and all computations shall be conclusive and binding on the holders of
Shares.

   (f) A Form of Election must be received by the Exchange Agent by the close
of business of the last business day prior to the date of the Seller
Shareholders' Meeting in order to be effective. Such time on such date shall
hereinafter be referred to as the "Election Deadline." Any holder of Shares who
has made an election may at any time prior to the Election Deadline change or
withdraw its election by written notice to the Exchange Agent prior to the
Election Deadline. As soon as practicable after the Election Deadline, the
Exchange Agent shall determine the allocation of the cash portion of the Merger
Consideration and the stock portion of the Merger Consideration and shall
notify the Company of its determination.

   (g) The Shares of a holder who does not submit a Form of Election which is
received by the Exchange Agent prior to the Election Deadline (other than
Dissenting Shares) shall be converted into the right to receive the Stock
Consideration at the Effective Time. If the Company or the Exchange Agent shall
determine that any purported Cash Election was not properly made, the purported
Cash Election shall be deemed to be of no force and effect and the Shares of
the holder making such purported Cash Election shall be converted into the
right to receive the Stock Consideration at the Effective Time.

                                      A-3



   (h) No fractional shares of Company Common Stock shall be issued in the
Merger. All fractional shares of Company Common Stock that a holder of any
Shares would otherwise be entitled to receive as a result of the Merger shall
be aggregated. If a fractional share of Company Common Stock results from the
aggregation, the holder shall be entitled to receive, in lieu thereof, a cash
amount, without interest, determined by multiplying the Average Trading Price
by the fraction of a share of Company Common Stock to which the holder would
otherwise have been entitled. As promptly as practicable after the
determination of the amount of cash, if any, to be paid to holders of
fractional share interests, the Exchange Agent shall so notify the Company, and
the Company shall deposit that amount with the Exchange Agent and shall cause
the Exchange Agent to forward payments to the holders of fractional share
interests, subject to and in accordance with the terms of this Section 1.7.

   (i) Each share of Seller Common Stock held by the Company or any direct or
indirect wholly owned Company Subsidiary or Seller Subsidiary for its own
account shall be canceled and extinguished at the Effective Time without
conversion thereof into the Merger Consideration or payment therefor.

   (j) Notwithstanding anything in this Agreement to the contrary, shares of
Seller Common Stock which are issued and outstanding immediately prior to the
Effective Time and which are held by shareholders or beneficial owners who have
validly exercised and perfected dissenter's rights with respect to those Shares
under Sections 302A.471 and 302A.473 of the MBCA and have not withdrawn or lost
such rights (the "Dissenting Shares") shall not be converted into or be
exchangeable for the right to receive the Merger Consideration in accordance
with this Section 1.7, unless and until such holders or beneficial owners shall
have failed to perfect or shall have effectively withdrawn or lost their
dissenter's rights with respect to such Dissenting Shares under the MBCA.
Dissenting Shares shall be treated in accordance with Sections 302A.471 and
302A.473 of the MBCA, if and to the extent applicable. If, after the Effective
Time, any such holder or beneficial owner shall have failed to perfect or shall
have effectively withdrawn or lost such right to dissent with respect to any
Dissenting Shares, such Dissenting Shares shall thereupon be treated as if they
had been converted into and become exchangeable only for the right to receive,
as of the Effective Time, the Stock Consideration in accordance with this
Section 1.7, without any interest thereon. Seller shall give the Company (a)
prompt notice of each and every notice of a shareholder's or beneficial owner's
intent to demand payment of the "fair value" of the shareholder's or beneficial
owner's Shares, attempted withdrawals of such demands, and any other
instruments served pursuant to the MBCA and received by the Seller relating to
rights to be paid the "fair value" of Shares, as provided in Sections 302A.471
and 302A.473 of the MBCA and (b) the opportunity to direct all negotiations and
proceedings with respect to such demands for "fair value." Seller shall not,
except with the prior written consent of the Company, voluntarily make any
payment with respect to, offer to settle or settle, or approve any withdrawal
of any such demands for "fair value."

   (k) Each option to purchase shares of Seller Common Stock (each, a "Seller
Option") outstanding under any stock option plan immediately prior to the
Effective Time, whether or not vested or exercisable, shall be converted into
the right to receive cash from the Company in an amount equal to (A) the number
of shares of Seller Common Stock subject to such Seller Option multiplied by
(B) $7.398 (the product of (A) and (B) shall be rounded to the nearest whole
cent), minus (C) the aggregate exercise price for such Seller Option. After the
Effective Time, each Seller Option shall represent only the right to receive
the cash amount described above and shall not represent a right to receive any
securities of the Company.

   SECTION 1.8 Exchange of Certificates.

   (a) Exchange Agent. The Company shall deposit, or shall cause to be
deposited, from time to time, with a bank or trust company designated by the
Company and which may be an affiliate of the Company (the "Exchange Agent"),
for the benefit of the holders of Shares, for exchange in accordance with this
Article I, through the Exchange Agent, the Merger Consideration, together with
any dividends or distributions with respect thereto, if any, to be paid in
respect of Shares pursuant to this Article I (the "Exchange Fund"). Such
deposits shall be made after the Effective Time as requested by the Exchange
Agent in order for the Exchange Agent to promptly deliver the Merger
Consideration.

                                      A-4



   (b) Exchange Procedures. As soon as reasonably practicable after the
Effective Time, the Exchange Agent shall mail to each holder of record of a
certificate representing Shares which were converted into the right to receive
the Merger Consideration pursuant to Section 1.7 (each, a "Certificate" and
collectively, the "Certificates"), (i) a letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Exchange
Agent and shall be in such form and have such other provisions as the Company
may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for the Merger Consideration. Upon
surrender of a Certificate for cancellation to the Exchange Agent together with
such letter of transmittal, duly executed, the holder of such Certificate shall
be entitled to receive in exchange therefor the Merger Consideration and any
unpaid dividends and distributions thereon as provided in this Article I, which
such holder has the right to receive in respect of the Certificate surrendered
pursuant to the provisions of this Article I, and the Certificate so
surrendered shall forthwith be canceled. In the event of a transfer of
ownership of Shares which is not registered in the transfer records of the
Seller, a transferee may exchange the Certificate representing such Shares for
the Merger Consideration and any unpaid dividends and distributions thereon as
provided in this Article I if the Certificate representing such Shares is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. In the event any Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
person claiming such Certificate to be lost, stolen or destroyed and the
posting by such person of a bond in such amount as the Company may direct as
indemnity against any claim that may be made against it or the Exchange Agent
with respect to such Certificate, the Exchange Agent will issue in exchange for
such lost, stolen or destroyed Certificate the Merger Consideration and any
unpaid dividends and distributions thereon as provided in this Article I, which
such holder would have had the right to receive in respect of such lost, stolen
or destroyed Certificate. Until surrendered as contemplated by this Section
1.8, each Certificate shall be deemed at any time after the Effective Time to
represent only the right to receive upon such surrender the Merger
Consideration and any unpaid dividends and distributions thereon as provided in
this Article I.

   (c) Distributions with Respect to Unexchanged Shares. No dividends or other
distributions declared or made after the Effective Time with respect to Company
Common Stock with a record date after the Effective Time shall be paid to the
holder of any unsurrendered Certificate with respect to the shares of Company
Common Stock issuable in exchange for the Shares represented thereby, and no
cash payment in lieu of fractional shares shall be paid to any such holder
pursuant to Section 1.7(h), until the holder of such Certificate shall
surrender such Certificate. Subject to the effect of applicable laws, following
surrender of any such Certificate, there shall be paid to the holder of the
certificates representing whole shares of Company Common Stock issued in
exchange therefor, without interest, (i) promptly, the amount of any cash
payable with respect to a fractional share of Company Common Stock to which
such holder is entitled pursuant to Section 1.7(h) and the amount of dividends
or other distributions with a record date after the Effective Time theretofore
paid with respect to such whole shares of Company Common Stock, and (ii) at the
appropriate payment date, the amount of dividends or other distributions, with
a record date after the Effective Time but prior to surrender and a payment
date occurring after surrender, payable with respect to such whole shares of
Company Common Stock.

   (d) No Further Rights in the Shares. All Merger Consideration issued or paid
upon conversion of the Shares in accordance with the terms hereof (including
any cash paid pursuant to Section 1.7(h)) shall be deemed to have been issued
or paid in full satisfaction of all rights pertaining to such Shares.

   (e) Termination of Exchange Fund. Any portion of the Exchange Fund which
remains undistributed to the former shareholders of Seller for six (6) months
after the Effective Time shall be delivered to the Company, upon demand, and
any former shareholders of Seller who have not theretofore complied with this
Article I shall thereafter look only to the Company to claim the Merger
Consideration to which they are entitled, any cash in lieu of fractional shares
of Company Common Stock and any dividends or distributions with respect to
Company Common Stock, in each case without interest thereon, and subject to
Section 1.8(f).

                                      A-5



   (f) No Liability. Neither the Company nor the Seller shall be liable to any
former holder of Shares for any shares of Company Common Stock (or dividends or
distributions with respect thereto) or cash or other payment delivered to a
public official pursuant to any abandoned property, escheat or similar laws.

   (g) Withholding Rights. The Company shall be entitled to deduct and withhold
from the consideration otherwise payable pursuant to this Agreement to any
former holder of Shares or any holder of Seller Options such amounts as the
Company is required to deduct and withhold with respect to the making of such
payment under the Code, or any provision of state, local or foreign tax law. To
the extent that amounts are so withheld by the Company, such withheld amounts
shall be treated for all purposes of this Agreement as having been paid to the
former holder of the Shares or the former holder of Seller Options, as the case
may be, in respect of which such deduction and withholding was made by the
Company.

   SECTION 1.9 Stock Transfer Books. At the Effective Time, the stock transfer
books of Seller shall be closed and there shall be no further registration of
transfers of shares of Seller Common Stock thereafter on the records of Seller.
From and after the Effective Time, the holders of certificates evidencing
ownership of shares of Seller Common Stock outstanding immediately prior to the
Effective Time shall cease to have any rights with respect to such Shares
except as otherwise provided herein or by law. On or after the Effective Time,
any Certificates presented to the Exchange Agent or the Company for any reason
shall be converted into the Merger Consideration in accordance with this
Article I.

   SECTION 1.10 Adjustments for Dilution and Other Matters. If, after the date
of this Agreement and during the period in which the Average Trading Price is
determined, the Company shall declare a stock dividend or distribution upon or
subdivide, split up, reclassify or combine the Company Common Stock or declare
a dividend or make a distribution on the Company Common Stock in any security
convertible into Company Common Stock, appropriate adjustment or adjustments,
if any, will be made to the Merger Consideration and the Stock Consideration
determined pursuant to Sections 1.6(a) and 1.7(a).

   SECTION 1.11 Company Common Stock. The shares of Company Common Stock issued
and outstanding immediately prior to the Effective Time shall be unaffected by
the Merger and, at the Effective Time, such shares shall remain issued and
outstanding.

             ARTICLE II--REPRESENTATIONS AND WARRANTIES OF SELLER

   Except as set forth in the Disclosure Schedule delivered by Seller to the
Company prior to the execution of this Agreement (the "Seller Disclosure
Schedule"), which shall identify exceptions by specific Section references,
Seller hereby represents and warrants to the Company that:

   SECTION 2.1 Organization and Qualification; Subsidiaries.

   (a) Seller is a corporation duly organized, validly existing and in good
standing under the laws of the State of Minnesota, and is a registered
financial holding company under the Bank Holding Company Act of 1956, as
amended (the "BHCA"). Each subsidiary of Seller ("Seller Subsidiary," or
collectively the "Seller Subsidiaries") is a federally chartered national bank
or a corporation duly organized, validly existing and in good standing under
the laws of the state of its incorporation or organization. Each of Seller and
the Seller Subsidiaries has the requisite corporate power and authority and is
in possession of all franchises, grants, authorizations, licenses, permits,
easements, consents, certificates, approvals and orders ("Seller Approvals")
necessary to own, lease and operate its properties and to carry on its business
as it is now being conducted, including appropriate authorizations from the
Board of Governors of the Federal Reserve System (the "Federal Reserve Board"),
the Office of the Comptroller of the Currency (the "OCC"), the Federal Deposit
Insurance Corporation (the "FDIC"), the Minnesota Secretary of State and the
Minnesota Department of Commerce, and neither Seller nor any Seller Subsidiary
has received any notice of proceedings relating to the revocation or
modification of any Seller

                                      A-6



Approvals, except in each case where the revocations or modifications, or the
failure to have such power, authority and Seller Approvals would not,
individually or in the aggregate, have a Material Adverse Effect (as defined in
Section 2.1(d)) on Seller and Seller Subsidiaries, taken as a whole.

   (b) Seller and each Seller Subsidiary is duly qualified or licensed as a
foreign corporation or foreign limited liability company to do business, and is
in good standing, in each jurisdiction where the character of its properties
owned, leased or operated by it or the nature of its activities makes such
qualification or licensing necessary, except for such failures to be so duly
qualified or licensed and in good standing that would not, either individually
or in the aggregate, have a Material Adverse Effect on Seller or Seller
Subsidiaries, taken as a whole.

   (c) A true and complete list of all of the Seller Subsidiaries, together
with (i) the Seller's percentage ownership of each Seller Subsidiary and (ii)
laws under which the Seller Subsidiary is incorporated or organized is set
forth on Annex A. Except as set forth on Annex A, Seller and/or one or more of
the Seller Subsidiaries owns beneficially and of record all of the outstanding
shares of capital stock or limited liability company interests of each of the
Seller Subsidiaries. Except for the subsidiaries set forth on Annex A, Seller
does not directly or indirectly own any equity or similar interests in, or any
interests convertible into or exchangeable or exercisable for any equity or
similar interest in, any corporation, partnership, joint venture or other
business association or entity other than in the ordinary course of business,
and in no event in excess of 5% of the outstanding equity securities of such
entity.

   (d) As used in this Agreement, the term "Material Adverse Effect" means,
with respect to the Company or the Seller, as the case may be, any effect that
(i) is material and adverse to the business, assets, liabilities, results of
operations or financial condition of the Company and the Company Subsidiaries
(as defined in Section 3.1(a)) taken as a whole or the Seller and Seller
Subsidiaries taken as a whole, respectively, or (ii) materially impairs the
ability of the Company or Seller, respectively, to consummate the transactions
contemplated hereby; provided, however, that Material Adverse Effect shall not
be deemed to include the impact of (a) compliance with the terms of, or the
taking of actions contemplated by, this Agreement, (b) changes in laws and
regulations or interpretations thereof that are generally applicable to the
banking industry, (c) changes in generally accepted accounting principles that
are generally applicable to the banking industry, (d) reasonable expenses
incurred in connection with the transactions contemplated hereby, and (e)
changes attributable to or resulting from changes in general economic
conditions affecting banks or their holding companies generally, including
changes in the prevailing level of interest rates.

   (e) The minute books of the Seller and each of the Seller Subsidiaries
contain true, complete and accurate records in all material respects of all
meetings and other corporate actions held or taken since January 1, 1998, of
their respective shareholders and Boards of Directors (including committees of
their respective Boards of Directors).

   SECTION 2.2 Articles of Incorporation and By-Laws. Seller has heretofore
furnished to the Company a complete and correct copy of the Articles of
Incorporation and the By-Laws, as amended or restated, of Seller ("Seller
Articles" and "Seller By-Laws," respectively) and the Articles of Incorporation
and the By-Laws of each Seller Subsidiary (the "Subsidiary Organizational
Documents"). The Seller Articles, the Seller By-Laws and the Subsidiary
Organizational Documents are in full force and effect. Neither Seller nor any
Seller Subsidiary is in violation of any of the provisions of the Seller
Articles, the Seller By-Laws or the Subsidiary Organizational Documents.

   SECTION 2.3 Capitalization. The authorized capital stock of Seller consists
of 5,000,000 shares of Series A Seller Common Stock and 15,000,000 shares of
Series B Seller Common Stock. As of the date of this Agreement, (i) 2,499,709
shares of Series A Seller Common Stock and 5,450,590 shares of Series B Seller
Common Stock are issued and outstanding, all of which are duly authorized,
validly issued, fully paid and non-assessable, and not issued in violation of
any preemptive right of any Seller shareholder and (ii) 1,310,425 shares

                                      A-7



of Seller Common Stock are reserved for future issuance pursuant to outstanding
stock options issued pursuant to Seller's stock option plans. Except as set
forth in clause (ii), above, there are no outstanding options, warrants or
other rights, agreements, arrangements or commitments of any character,
including without limitation voting agreements or arrangements, relating to the
issued or unissued capital stock or limited liability company interests of
Seller or any Seller Subsidiary or obligating Seller or any Seller Subsidiary
to issue or sell any shares of capital stock or limited liability company
interests of, or other equity interests in, Seller or any Seller Subsidiary.
All shares of Seller Common Stock subject to issuance as aforesaid, upon
issuance on the terms and conditions specified in the instruments pursuant to
which they are issuable, shall be duly authorized, validly issued, fully paid
and non-assessable. There are no obligations, contingent or otherwise, of
Seller or any Seller Subsidiary to repurchase, redeem or otherwise acquire any
shares of Seller Common Stock or the capital stock or limited liability company
interests of any Seller Subsidiary or to provide funds to or make any
investment (in the form of a loan, capital contribution or otherwise) in any
Seller Subsidiary or any other entity, except for loan commitments and other
funding obligations entered into in the ordinary course of business. Except as
set forth on the Seller Disclosure Schedule, each of the outstanding shares of
capital stock or limited liability company interests of each Seller Subsidiary
are duly authorized, validly issued, fully paid and non-assessable, and not
issued in violation of any preemptive rights of any Seller Subsidiary
shareholder, and such shares or limited liability company interests owned by
Seller or another Seller Subsidiary are owned free and clear of all security
interests, liens, claims, pledges, agreements, limitations of Seller's voting
rights, charges or other encumbrances of any nature whatsoever.

   SECTION 2.4 Authority. Seller has the requisite corporate power and
authority to execute and deliver this Agreement, to perform its obligations
hereunder and to consummate the transactions contemplated hereby (other than,
with respect to the Merger, the approval and adoption of this Agreement by
Seller's shareholders in accordance with the MBCA and the Seller Articles and
Seller By-Laws). The execution and delivery of this Agreement by Seller and the
consummation by Seller of the transactions contemplated hereby have been duly
and validly authorized by all necessary corporate action, including without
limitation Seller's Board of Directors, and no other corporate proceedings on
the part of Seller are necessary to authorize this Agreement or to consummate
the transactions so contemplated hereby (other than, with respect to the
Merger, the approval and adoption of this Agreement and the Plan of Merger by
Seller's shareholders in accordance with the MBCA and the Seller Articles and
Seller By-Laws). This Agreement has been duly executed and delivered by Seller,
and assuming the due authorization, execution and delivery by Company,
constitutes a valid and binding obligation of Seller enforceable against Seller
in accordance with its terms, except as enforcement may be limited by laws
affecting insured depository institutions, general principles of equity whether
applied in a court of law or a court of equity and by bankruptcy, insolvency
and similar laws affecting creditors' rights and remedies generally.

   SECTION 2.5 No Conflict; Required Filings and Consents.

   (a) The execution and delivery of this Agreement by Seller do not, and the
performance of this Agreement and the transactions contemplated hereby by
Seller shall not, (i) conflict with or violate the Seller Articles or Seller
By-Laws or the Subsidiary Organizational Documents, (ii) conflict with or
violate any domestic (federal, state or local) or foreign law, statute,
ordinance, rule, regulation, order, judgment or decree (collectively, "Laws")
applicable to Seller or any Seller Subsidiary or by which its or any of their
respective properties is bound or affected, or (iii) result in any breach of or
constitute a default (or an event that with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, or result in the creation of a lien
or encumbrance on any of the properties or assets of Seller or any Seller
Subsidiary pursuant to, any note, bond, mortgage, indenture, contract,
agreement, lease, license, permit, franchise or other instrument or obligation
to which Seller or any Seller Subsidiary is a party or by which Seller or any
Seller Subsidiary or its or any of their respective properties is bound or
affected, except in the case of clauses (ii) and (iii) for any such conflicts,
violations, breaches, defaults or other occurrences that would not,
individually or in the aggregate, have a Material Adverse Effect on Seller and
the Seller Subsidiaries, taken as a whole. Sections 302A.671, 302A.673 and
302A.675 of the MBCA are inapplicable to the Merger, this Agreement and the
transactions contemplated hereby or entered into in connection herewith
(including without

                                      A-8



limitation the execution of that certain Shareholder Voting Agreement dated as
of the date hereof among the Company and certain shareholders of the Seller).
Without limiting, the generality of the foregoing, the Seller is not an
"issuing public corporation," as such term is defined in Section 302A.011 Subd.
39 of the MBCA. No other "control share acquisition," "fair price" (other than
Sections 302A.471 and 302A.473 of the MBCA) or other anti-takeover laws or
regulations enacted under state or federal laws in the United States apply to
the Merger, this Agreement or any of the transactions contemplated hereby or
entered into in connection herewith (including, without limitation, the
execution of the Shareholder Voting Agreement).

   (b) The execution and delivery of this Agreement by Seller do not, and the
performance of this Agreement by Seller shall not, require any consent,
approval, authorization or permit of, or filing with or notification to, any
governmental or regulatory authority, domestic or foreign, except (i) for
applicable requirements, if any, of the Securities Act of 1933, as amended (the
"Securities Act"), the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), state securities or blue sky laws ("Blue Sky Laws"), the BHCA,
the banking laws and regulations of the United States of America (the "USBL"),
and the filing and recordation of appropriate merger or other documents as
required by the MBCA and the WBCL and (ii) where the failure to obtain such
consents, approvals, authorizations or permits, or to make such filings or
notifications, would not prevent or delay consummation of the Merger or
otherwise prevent Seller from performing its obligations under this Agreement,
and would not have a Material Adverse Effect on Seller or Seller Subsidiaries,
taken as a whole.

   SECTION 2.6 Compliance; Permits. Neither Seller nor any Seller Subsidiary is
in conflict with, or in default or violation of, (i) any Law applicable to
Seller or any Seller Subsidiary or by which its or any of their respective
properties is bound or affected, or (ii) any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which Seller or any Seller Subsidiary is a party or by which
Seller or any Seller Subsidiary or its or any of their respective properties is
bound or affected, except for any such conflicts, defaults or violations which
would not, individually or in the aggregate, have a Material Adverse Effect on
Seller or Seller Subsidiaries, taken as a whole.

   SECTION 2.7 Securities and Banking Reports; Financial Statements.

   (a)  Seller and each Seller Subsidiary have filed all forms, reports and
documents required to be filed with the Federal Reserve Board, the Office of
the Comptroller of the Currency, the Minnesota Department of Commerce and any
other applicable federal or state securities or banking authorities (all such
reports and statements are collectively referred to as the "Seller Reports").
The Seller Reports, including all Seller Reports filed after the date of this
Agreement, (i) were or will be prepared in all material respects in accordance
with the requirements of applicable Law and (ii) did not at the time they were
filed, or will not at the time they are filed, contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

   (b) Each of the consolidated financial statements (including, in each case,
any related notes thereto) contained in the Seller Reports, including any
Seller Reports filed since the date of this Agreement and prior to or on the
Effective Time, have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
involved (except as may be indicated in the notes thereto) and each fairly
presents the consolidated financial position of Seller and Seller Subsidiaries
as of the respective dates thereof and the consolidated results of its
operations and changes in financial position for the periods indicated, except
that any unaudited interim financial statements were or are subject to normal
and recurring year-end adjustments, which were not or are not expected to be
material in amount.

   (c) Except (i) for those liabilities that are fully reflected or reserved
against on the consolidated balance sheet of the Seller for the fiscal year
ended December 31, 2000, (ii) for liabilities incurred in the ordinary course
of business consistent with past practice since December 31, 2000, and (iii) as
set forth in Section 2.7 of the Seller Disclosure Schedule, neither Seller nor
any Seller Subsidiary has incurred any liability of any nature

                                      A-9



whatsoever (whether absolute, accrued, contingent or otherwise due or to become
due), that, either alone or when combined with all similar liabilities, has
had, or would reasonably be expected to have, a Material Adverse Effect on the
Seller and the Seller Subsidiaries, taken as a whole.

   SECTION 2.8 Absence of Certain Changes or Events. Except as set forth in
Section 2.8 of the Seller Disclosure Schedule, since December 31, 2000 to the
date of this Agreement, Seller and the Seller Subsidiaries have conducted their
businesses only in the ordinary course and in a manner consistent with past
practice and, since December 31, 2000, there has not been (i) any change in the
financial condition, results of operations or business of Seller and any of the
Seller Subsidiaries having a Material Adverse Effect on Seller or the Seller
Subsidiaries, taken as a whole, (ii) any damage, destruction or loss (whether
or not covered by insurance) with respect to any assets of Seller or any of the
Seller Subsidiaries having a Material Adverse Effect on Seller and the Seller
Subsidiaries, taken as a whole, (iii) any change by Seller in its accounting
methods, principles or practices, (iv) any revaluation by Seller of any of its
assets in any material respect, (v) except for regular quarterly cash dividends
on Seller Common Stock with usual record and payment dates, to the date of this
Agreement, any declaration, setting aside or payment of any dividends or
distributions in respect of shares of Seller Common Stock or any redemption,
purchase or other acquisition of any of its securities or any of the securities
of any Seller Subsidiary, (vi) increased the wages, salaries, compensation,
pension, or other fringe benefits or perquisites payable to any executive
officer, employee, or director from the amount thereof in effect as of January
1, 2001 (which amounts have been previously disclosed to Company), granted any
severance or termination pay, entered into any contract to make or grant any
severance or termination pay, or paid any bonus, (vii) suffered any strike,
work stoppage, slow-down or other labor disturbance, (viii) been a party to a
collective bargaining agreement, contract or other agreement or understanding
with a labor union or organization, or (ix) had any union organizing activities.

   SECTION 2.9 Absence of Litigation.

   (a) Except as set forth in Section 2.9 of the Seller Disclosure Schedule,
neither the Seller nor any of the Seller Subsidiaries is a party to any, and
there are no pending or, to the best of the Seller's knowledge, threatened,
legal, administrative, arbitral or other proceedings, claims, actions or
governmental or regulatory investigations of any nature against the Seller or
any of the Seller Subsidiaries or challenging the validity or propriety of the
transactions contemplated by this Agreement as to which there is reasonable
probability of an adverse determination and which, if adversely determined,
would, individually or in the aggregate, have a Material Adverse Effect on the
Seller and the Seller Subsidiaries, taken as a whole.

   (b) There is no injunction, order, judgment, decree or regulatory
restriction imposed upon the Company, any of the Seller Subsidiaries or the
assets of the Seller or any of the Seller Subsidiaries which has had a Material
Adverse Effect on the Seller and the Seller Subsidiaries, taken as a whole.

   SECTION 2.10 Employee Benefit Plans.

   (a) Current Plans. Section 2.10(a) of the Seller Disclosure Schedule lists
(i) all employee benefit plans (as defined in Section 3(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA")), and all bonus,
stock option, stock purchase, restricted stock, incentive, deferred
compensation, retiree medical or life insurance, supplemental retirement,
severance or other benefit plans, programs or arrangements, and all material
employment, termination, severance or other employment contracts or employment
agreements, with respect to which Seller or any Seller Subsidiary has any
obligation (collectively, the "Plans"). Seller has furnished or made available
to the Company a complete and accurate copy of each Plan (or a description of
the Plans, if the Plans are not in writing) and a complete and accurate copy of
each material document prepared in connection with each such Plan, including,
without limitation, and where applicable, a copy of (i) each trust or other
funding arrangement, (ii) each summary plan description and summary of material
modifications, (iii) the three (3) most recently filed IRS Forms 5500 and
related schedules, (iv) the most recently issued IRS determination letter for

respect to each such Plan.

                                     A-10



   (b) Absence of Certain Types of Plans. Except as disclosed in the Seller
Disclosure Schedule, no member of Seller's "controlled group," within the
meaning of Section 4001(a)(14) of ERISA, maintains or contributes to, or within
the five years preceding the Effective Time has maintained or contributed to,
an employee pension benefit plan subject to Title IV of ERISA ("Title IV
Plan"). No Title IV Plan is a "multiemployer pension plan" as defined in
Section 3(37) of ERISA. Except as disclosed in the Seller Disclosure Schedule,
none of the Plans obligates Seller or any of the Seller Subsidiaries to pay
material separation, severance, termination or similar-type benefits solely as
a result of any transaction contemplated by this Agreement or as a result of a
"change in control," within the meaning of such term under Section 280G of the
Code. Except as disclosed in the Seller Disclosure Schedule, or as required by
COBRA, none of the Plans provides for or promises retiree medical, disability
or life insurance benefits to any current or former employee, officer or
director of Seller or any of the Seller Subsidiaries. Each of the Plans is
subject only to the laws of the United States or a political subdivision
thereof.

   (c) Compliance with Applicable Law. Except as disclosed in the Seller
Disclosure Schedule, each Plan has been operated in all respects in accordance
with the requirements of all applicable Law and all persons who participate in
the operation of such Plans and all Plan "fiduciaries" (within the meaning of
Section 3(21) of ERISA) have acted in accordance with the provisions of all
applicable Law, except where such violations of applicable Law would not,
individually or in the aggregate, have a Material Adverse Effect on Seller and
the Seller Subsidiaries, taken as a whole. Seller and the Seller Subsidiaries
have performed all obligations required to be performed by any of them under,
are not in any respect in default under or in violation of, and Seller and the
Seller Subsidiaries have no knowledge of any default or violation by any party
to, any Plan, except where such failures, defaults or violations would not,
individually or in the aggregate, have a Material Adverse Effect on Seller and
the Seller Subsidiaries, taken as a whole. No legal action, suit or claim is
pending or, to the knowledge of Seller or the Seller Subsidiaries, threatened
with respect to any Plan (other than claims for benefits in the ordinary
course) and, except as disclosed in the Seller Disclosure Schedule, to the
knowledge of Seller or the Seller Subsidiaries, no fact or event exists that
could reasonably be expected to give rise to any such action, suit or claim.
Except as disclosed in the Seller Disclosure Schedule, neither Seller nor any
Seller Subsidiary has incurred any material liability under Section 302 of
ERISA or Section 412 of the Code that has not been satisfied in full and no
condition exists that presents a material risk of incurring any such liability.

   (d) Qualification of Certain Plans. Each Plan that is intended to be
qualified under Section 401(a) of the Code or Section 401(k) of the Code
(including each trust established in connection with such a Plan that is
intended to be exempt from Federal income taxation under Section 501(a) of the
Code) has received a favorable determination letter from the IRS (as defined
herein) that it is so qualified, and, except as disclosed in the Seller
Disclosure Schedule, Seller is not aware of any fact or event that has occurred
since the date of such determination letter from the IRS to adversely affect
the qualified status of any such Plan. Except as disclosed on the Seller
Disclosure Schedule, no trust maintained or contributed to by the Seller or any
of the Seller Subsidiaries is intended to be qualified as a voluntary
employees' beneficiary association or is intended to be exempt from federal
income taxation under Section 501(c)(9) of the Code.

   (e) Absence of Certain Liabilities and Events. Except for matters disclosed
in the Seller Disclosure Schedule, there has been no non-exempt prohibited
transaction (within the meaning of Section 406 of ERISA or Section 4975 of the
Code) with respect to any Plan. Seller and each of the Seller Subsidiaries has
not incurred any liability for any excise tax arising under Sections 4971
through 4980E of the Code that would individually or in the aggregate have a
Material Adverse Effect on the Seller and the Seller Subsidiaries, taken as a
whole, and, to the knowledge of Seller or the Seller Subsidiaries, no fact or
event exists that could reasonably be expected to give rise to any such
liability.

   (f) Plan Contributions. All contributions, premiums or payments required to
be made with respect to any Plan have been made on or before their due dates.

                                     A-11



   (g) Employment Contracts. Except for employment, severance, consulting or
other similar contracts with any employees, consultants, officers or directors
of Seller or any of the Seller Subsidiaries disclosed in Section 2.10(g) of the
Seller Disclosure Schedule, neither Seller nor any Seller Subsidiary is a party
to any such contracts. Neither Seller nor any Seller Subsidiary is a party to
any collective bargaining agreements.

   (h) Effect of Agreement. Except as disclosed on the Seller Disclosure
Schedule, the consummation of the transactions contemplated by this Agreement
will not, either alone or in conjunction with another event, entitle any
current or former employee of Seller or any Seller Subsidiary to severance pay,
unemployment compensation or any other payment, except as expressly provided
herein, or accelerate the time of payment or vesting or increase the
compensation due any such employee or former employee, in each case, except as
expressly provided herein.

   SECTION 2.11 Registration Statement; Proxy Statement/Prospectus. The
information supplied by Seller for inclusion in the Registration Statement (as
defined in Section 3.8) shall not at the time the Registration Statement is
declared effective contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading. The information supplied by Seller for inclusion in
the proxy statement/prospectus to be sent to the shareholders of Seller in
connection with the meeting of Seller's shareholders to consider the approval
of this Agreement, the Plan of Merger and the Merger (the "Seller Shareholders'
Meeting") (such proxy statement/prospectus as amended or supplemented is
referred to herein as the "Proxy Statement/Prospectus") shall not at the date
the Proxy Statement/Prospectus (or any amendment thereof or supplement thereto)
is first mailed to shareholders, at the time of the Seller Shareholders'
Meeting and at the Effective Time, be false or misleading with respect to any
material fact required to be stated herein, or omit to state any material fact
required to be stated therein or necessary in order to make the statements made
therein, in the light of the circumstances under which they are made, not
misleading. If at any time prior to the Effective Time any event relating to
Seller or any of its affiliates, officers or directors should be discovered by
Seller which should be set forth in an amendment to the Registration Statement
or a supplement to the Proxy Statement/Prospectus, Seller shall promptly inform
the Company. The Proxy Statement/Prospectus shall comply in all material
respects as to form with the requirements of the Securities Act, the Exchange
Act (to the extent applicable) and the rules and regulations thereunder.
Notwithstanding the foregoing, Seller makes no representation or warranty with
respect to any information about, or supplied or omitted by, the Company which
is contained in any of the foregoing documents.

   SECTION 2.12 Title to Property. Except as set forth in Section 2.12 of the
Seller Disclosure Schedule, Seller and each of the Seller Subsidiaries has good
and marketable title to all of their respective properties and assets, real and
personal, free and clear of all mortgage liens, and free and clear of all other
liens, charges and encumbrances except liens for taxes not yet due and payable,
pledges to secure deposits and such minor imperfections of title, if any, as do
not materially detract from the value of or interfere with the present use of
the property affected thereby or which, individually or in the aggregate, would
not have a Material Adverse Effect on Seller and the Seller Subsidiaries, taken
as a whole; and all leases pursuant to which Seller or any of the Seller
Subsidiaries lease from others material amounts of real or personal property
are in good standing, valid and effective in accordance with their respective
terms, and there is not, under any of such leases, any existing material
default or event of default by Seller or any Seller Subsidiary (or event which
with notice or lapse of time, or both, would constitute a material default by
Seller or any Seller Subsidiary and in respect of which the Seller or such
Seller Subsidiary has not taken adequate steps to prevent such a default from
occurring). Substantially all of Seller's and each of the Seller Subsidiaries'
buildings and equipment in regular use have been reasonably maintained and are
in good and serviceable condition, reasonable wear and tear excepted.

   SECTION 2.13 Environmental Matters. Except as set forth in Section 2.13 of
the Seller Disclosure Schedule, Seller represents and warrants that to the best
of Seller's knowledge: (i) each of the Seller, the Seller Subsidiaries,
properties owned or operated by the Seller or the Seller Subsidiaries and the
Participation Facilities (each as hereinafter defined) are and have been in
compliance with all applicable federal, state and local laws

                                     A-12



including common law, rules, guidance, regulations and ordinances and with all
applicable decrees, orders, judgments, and contractual obligations relating to
the environment, health, safety, natural resources, wildlife or "Hazardous
Materials" which are hereinafter defined as chemicals, pollutants,
contaminants, wastes, toxic substances, compounds, products, solid, liquid,
gas, petroleum or other regulated substances or materials which are hazardous,
toxic or otherwise harmful to health, safety, natural resources, or the
environment ("Environmental Laws"), except for violations which, either
individually or in the aggregate, would not have a Material Adverse Effect on
Seller or Seller Subsidiaries; (ii) during and prior to the period of (a) the
Seller's or any of the Seller Subsidiaries' ownership or operation of any of
their respective current properties or (b) the Seller's or any of the Seller's
Subsidiaries' participation in the management of any Participation Facility,
Hazardous Materials have not been generated, treated, stored, transported,
released or disposed of in, on, under, above, from or affecting any such
property, except where such release, generation, treatment, storage,
transportation, or disposal would not have, either individually or in the
aggregate, a Material Adverse Effect on the Seller or Seller's Subsidiaries;
(iii) there is no asbestos or any material amount of ureaformaldehyde materials
in or on any property owned or operated by Seller or Seller's Subsidiaries or
any or Participation Facility and no electrical transformers or capacitors,
other than those owned by public utility companies, on any such properties
contain any PCB's; (iv) there are no underground or aboveground storage tanks
and there have never been any underground or aboveground storage tanks located
on, in or under any properties currently or formerly owned or operated by the
Seller or any of Seller's Subsidiaries or any Participation Facility; (v)

governmental agency or third party notifying the Seller or Seller's
Subsidiaries of any Environmental Claim; (vi) and there are no circumstances
with respect to any properties currently owned or operated by the Seller or any
of Seller's Subsidiaries or any Participation Facility that could reasonably be
anticipated (a) to form the basis for an Environmental Claim against Seller or
Seller's Subsidiaries or any properties currently or formerly owned or operated
by the Seller or any of Seller's Subsidiaries or any Participation Facility or
(b) to cause any properties currently owned or operated by the Seller or any of
Seller's Subsidiaries or any Participation Facility to be subject to any
restrictions on ownership, occupancy, use or transferability under any
applicable Environmental Law or require notification to or consent of any
Governmental Authority or third party pursuant to any Environmental Law.

   The following definitions apply for purposes of this Section 2.13: (a)
"Participation Facility" means any facility in which the Seller or any of the
Seller's Subsidiaries participates in the management and, where required by the
context, said term means the owner or operator of such property; (b)
"Environmental Claims" shall mean any and all administrative, regulatory,
judicial or private actions, suits, demands, demand letters, notices, claims,
liens, notices of non-compliance or violation, investigations, allegations,
injunctions or proceedings relating in any way to (i) any Environmental Law;

is a party to any agreement or memorandum of understanding with, or a party to
any commitment letter or similar undertaking to, or is subject to any order or
directive by, or is a recipient of any extraordinary supervisory letter which
restricts materially the conduct of its business (including any contract
containing covenants which limit the ability of Seller or of any Seller
Subsidiary to compete in any line of business or with any person or which
involve any restriction of the geographical area in which, or method by which,
Seller or any Seller Subsidiary may carry on its business (other than as may be
required by Law or applicable regulatory authorities)), or in any manner
relates to its capital adequacy, its credit policies or its management, except
as disclosed in the Seller Disclosure Schedule, nor has Seller been advised
that any federal, state, or governmental agency is contemplating issuing or
requesting (or is considering the appropriateness of issuing or requesting) any
such order, decree, agreement, memorandum of understanding, extraordinary
supervisory letter, commitment letter or similar submission, except as
disclosed by Seller in Section 2.14 of the Seller Disclosure Schedule.

                                     A-13



   SECTION 2.15 Taxes. Seller and the Seller Subsidiaries have timely filed all
material Tax Returns (as defined below) required to be filed by them, and
Seller and the Seller Subsidiaries have timely paid and discharged all material
Taxes (as defined below) due in connection with or with respect to the filing
of such Tax Returns, except such as are being contested in good faith by
appropriate proceedings and with respect to which Seller is maintaining
reserves adequate for their payment. To the best knowledge of the Seller, the
liability for Taxes set forth on each such Tax Return adequately reflects the
Taxes required to be reflected on such Tax Return. For purposes of this
Agreement, "Tax" or "Taxes" shall mean taxes, charges, fees, levies, and other
governmental assessments and impositions of any kind, payable to any federal,
state, local or foreign governmental entity or taxing authority or agency,

other similar assessments of any kind, and (iii) interest, penalties and
additions to tax imposed with respect thereto; and "Tax Returns" shall mean

including, without limitation, consolidated, combined and unitary tax returns.
For the purposes of this Section 2.15, references to the Seller and the Seller
Subsidiaries include former subsidiaries of Seller for the periods during which
any such corporations were owned, directly or indirectly, by Seller. Except as
otherwise disclosed in the Seller Disclosure Schedule, to the best knowledge of
the Seller, neither the IRS nor any other governmental entity or taxing
authority or agency is now asserting, either through audits, administrative
proceedings or court proceedings, any deficiency or claim for additional Taxes.
Except as otherwise disclosed, neither Seller nor any of the Seller
Subsidiaries has granted any waiver of any statute of limitations with respect
to, or any extension of a period for the assessment of, any Tax. Except as
otherwise disclosed in the Seller Disclosure Schedule and except for statutory
liens for current taxes not yet due, there are no material tax liens on any
assets of Seller or any of the Seller Subsidiaries. Except as otherwise
disclosed in the Seller Disclosure Schedule, neither Seller nor any of the
Seller Subsidiaries has received a ruling or entered into an agreement with the
IRS or any other taxing authority that would have a Material Adverse Effect on
Seller or the Seller Subsidiaries, taken as a whole, after the Effective Time.
Except as otherwise disclosed in the Seller Disclosure Schedule, no agreements
relating to allocating or sharing of Taxes exist among Seller and the Seller
Subsidiaries and no tax indemnities given by Seller or the Seller Subsidiaries
in connection with a sale of stock or assets remain in effect. Neither the
Seller nor any of the Seller Subsidiaries is required to include income either
(i) any amount in respect of any adjustment under Section 481 of the Code, or
(ii) any installment sale gain. Neither Seller nor any of the Seller
Subsidiaries has made an election under Section 341(f) of the Code.

   SECTION 2.16 Insurance. Section 2.16 of the Seller Disclosure Schedule lists
all material policies of insurance of Seller and the Seller Subsidiaries

liability for unpaid premiums or premium adjustments not properly reflected on
Seller's financial statements for the fiscal year ended December 31, 2000.

   SECTION 2.17 Brokers. No broker, finder or investment banker (other than RBC
Capital Markets) is entitled to any brokerage, finder's or other fee or
commission in connection with the transactions contemplated by this Agreement
based upon arrangements made by or on behalf of Seller. Prior to the date of
this Agreement, Seller has furnished to the Company a complete and correct copy
of all agreements between Seller and RBC Capital Markets pursuant to which such
firm would be entitled to any payment relating to the transactions contemplated
hereunder.

   SECTION 2.18 Tax Matters. Neither Seller nor, to the best of Seller's
knowledge, any of its affiliates has through the date of this Agreement taken
or agreed to take any action that would prevent the Merger from qualifying as a
reorganization under Section 368(a)(1)(A) of the Code.

                                     A-14



   SECTION 2.19 Material Adverse Effect. Since December 31, 2000, there has
been no Material Adverse Effect on Seller or the Seller Subsidiaries, taken as
a whole.

   SECTION 2.20 Material Contracts. Except as disclosed in the Seller

neither the Seller nor any Seller Subsidiary is a party to or obligated under
any contract, agreement or other instrument or understanding which is not
terminable by Seller or the Seller Subsidiary without additional payment or
penalty within 60 days and obligates Seller or any Seller Subsidiary for
payments or other consideration with a value in excess of $100,000.

   SECTION 2.21 Vote Required. The affirmative vote of the holders of a
majority of the then outstanding shares of Series A and Series B Seller Common
Stock voting together as a single class is the only vote of the holders of any
class or series of Seller capital stock necessary to approve this Agreement,
the Plan of Merger and the Merger.

          ARTICLE III--REPRESENTATIONS AND WARRANTIES OF THE COMPANY

   Except as set forth in the Disclosure Schedule delivered by the Company to

Schedule"), which shall identify exceptions by specific Section references, the
Company hereby represents and warrants to Seller that:

   SECTION 3.1 Organization and Qualification; Subsidiaries.

   (a) The Company is a corporation duly organized, validly existing and in
active status under the laws of the State of Wisconsin and a registered bank

Subsidiary" or, collectively, "Company Subsidiaries") is a bank, a corporation,
a limited liability company or another form of business entity duly organized,

organization or the United States of America. Each of the Company and the
Company Subsidiaries have the requisite corporate power and authority and are

necessary to own, lease and operate their respective properties and to carry on
their respective business as now being conducted, including appropriate
authorizations from the Federal Reserve Board, the FDIC, the DFI, the OCC or
the Office of Thrift Supervision and neither Company nor any Company Subsidiary
has received any notice of proceedings relating to the revocation or
modification of any Company Approvals, except in each case where the
revocations or modifications, or the failure to have such power, authority or
Company Approvals would not, individually or in the aggregate, have a Material
Adverse Effect on the Company and the Company Subsidiaries, taken as a whole.

   (b) The Company and each Company Subsidiary is duly qualified or licensed as
a foreign business entity to do business, and is in good standing, in each
jurisdiction where the character of its properties owned, leased or operated by
it or the nature of its activities makes such qualification or licensing
necessary, except for such failures to be so duly qualified or licensed and in
good standing that would not, either individually or in the aggregate, have a
Material Adverse Effect on the Company and the Company Subsidiaries, taken as a
whole.

   (c) A true and complete list of all of the Company Subsidiaries as of
February 28, 2001 is set forth in Exhibit 21 to the Company's Annual Report on
Form 10-K for the year ended December 31, 2000, ("Exhibit 21") previously

in, or any interests convertible into or exchangeable or exercisable for any

   SECTION 3.3 Capitalization.

   (a) The authorized capital stock of the Company consists of (i) 320,000,000

referred to herein as "Section 180.0622(2)(b) of the WBCL"). Except as set
forth in clauses (i)-(ii), above, as of the date of this Agreement there are no
options, warrants or other rights, agreements, arrangements or commitments of
any character relating to the issued or unissued capital stock of the Company
or obligating the Company to issue or sell any shares of capital stock of, or
other equity interests in, the Company.

   (b) The shares of Company Common Stock to be issued pursuant to the Merger
will, upon issuance in accordance with the provisions of this Agreement, be
duly authorized, validly issued, fully paid and non-assessable, except as
otherwise provided by Section 180.0622(2)(b) of the WBCL.

   SECTION 3.4  Authority. The Company has the requisite corporate power and

including without limitation, the Company's Board of Directors, and no other
corporate proceedings on the part of the Company are necessary to authorize
this Agreement or to consummate the transactions so contemplated hereby. This
Agreement has been duly and validly executed and delivered by the Company, and
assuming the due authorization, execution and delivery by the Seller,
constitutes a valid and binding obligation of the Company enforceable against
the Company in accordance with its terms, except as enforcement may be limited
by laws affecting insured depository institutions, general principles of
equity, whether applied in a court of law or a court of equity, and by
bankruptcy, insolvency and similar laws affecting creditors' rights and
remedies generally.

   SECTION 3.5 No Conflict; Required Filings and Consents.

   (a) The execution and delivery of this Agreement by the Company does not,

the performance of this Agreement by the Company shall not, require any
consent, approval, authorization or permit of, or filing with or notification
to, any governmental or regulatory authority, domestic or foreign, except (i)
for applicable requirements, if any, of the Securities Act, the Exchange Act,
Blue Sky Laws, the BHCA, and the filing and recordation of appropriate merger
or other documents as required by Wisconsin law and Minnesota law and (ii)
where the failure to obtain such consents, approvals, authorizations or
permits, or to make such filings or notifications, would not prevent or delay
consummation of the Merger, or otherwise prevent the Company from performing
its obligations under this Agreement, and would not have a Material Adverse
Effect on the Company or the Company Subsidiaries, taken as a whole.

   SECTION 3.6 Securities and Banking Reports; Financial Statements.

   (a) The Company and each Company Subsidiary have filed all forms, reports

presents the consolidated financial position of the Company and the Company
Subsidiaries as of the respective dates thereof and the consolidated results of
its operations and changes in financial position for the periods indicated,
except that any unaudited interim financial statements were or are subject to
normal and recurring year-end adjustments, which were not or are not expected
to be material in amount.

against on the consolidated statement of condition of the Company included in
the Company Form 10-K for the year ended December 31, 2000, as amended, (ii)

the Company Disclosure Schedule, neither Company nor any Company Subsidiary has
incurred any liability of any nature whatsoever (whether absolute, accrued,
contingent or otherwise and whether due or to become due) that, either alone or
when combined with all similar liabilities, has had, or would reasonably be
expected to have, a Material Adverse Effect on the Company and the Company
Subsidiaries, taken as a whole.

                                     A-17



   SECTION 3.7 Absence of Certain Changes or Events. Except as disclosed in the

Disclosure Schedule, since December 31, 2000 to the date of this Agreement, the
Company and the Company Subsidiaries have conducted their businesses only in
the ordinary course and in a manner consistent with past practice and, since
December 31, 2000, there has not been any change in the financial condition,
results of operations or business of the Company or any of the Company
Subsidiaries having a Material Adverse Effect on the Company and the Company
Subsidiaries, taken as a whole.

   SECTION 3.8 Registration Statement; Proxy Statement/Prospectus. The
information supplied by the Company for inclusion in the registration statement
of the Company (the "Registration Statement") pursuant to which the shares of
Company Common Stock to be issued in the Merger will be registered with the SEC

supplements thereto) is declared effective by the SEC, contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading. The
information supplied by the Company for inclusion in the Proxy

relating to the Company or any of its affiliates, officers or directors should
be discovered by the Company which should be set forth in an amendment to the
Registration Statement or a supplement to the Proxy Statement/Prospectus, the
Company will promptly inform the Seller. The Registration Statement and the
Proxy Statement/Prospectus shall comply in all material respects as to form
with the requirements of the Securities Act, the Exchange Act (to the extent
applicable) and the rules and regulations thereunder. Notwithstanding the
foregoing, the Company makes no representation or warranty with respect to any
information about, or supplied or omitted by, Seller which is contained in any
of the foregoing documents.

to the Company "comfort" letters of McGladrey & Pullen, LLP, Seller's
independent public accountants, dated the date on which the Registration
Statement shall become effective and the Effective Time, respectively, and
addressed to the Company, in a form reasonably satisfactory to the Company and
reasonably customary in scope and substance for letters delivered by
independent public accountants in connection with registration statements
similar to the Registration Statement and transactions such as those
contemplated by this Agreement.

   SECTION 4.4 No Solicitation of Transactions.

   (a) Seller shall immediately cease and cause to be terminated any existing
discussions or negotiations relating to a Competing Proposal (as defined
below), other than with respect to the Merger, with any parties conducted
heretofore. Seller will not, directly or indirectly, and will instruct its
directors, officers, employees, accountants, consultants, legal counsel,
agents, investment bankers, advisors and other representatives (collectively,
"Representatives") not to, directly or indirectly, initiate, solicit or
encourage (including by way of furnishing information or assistance), or take
any other action or facilitate, any inquiries or the making of any proposal
that constitutes, or may reasonably be expected to lead to, any Competing
Proposal, or enter into or maintain discussions or negotiate with any person in
furtherance of or relating to such inquiries or to obtain a Competing Proposal,
or agree to or endorse any Competing Proposal, or authorize or permit any
Representative of Seller or any of the Seller Subsidiaries to take any such
action, and Seller shall use its reasonable efforts to cause the
Representatives of Seller and the Seller Subsidiaries not to take any such
action, and Seller shall promptly notify the Company if any such inquiries or
proposals are made regarding a Competing Proposal, and Seller shall keep the
Company informed, on a current basis, of the status and terms of any such
proposals; provided, however, that prior to such time as the shareholders of
Seller shall have adopted and approved this Agreement, the Plan of Merger, and
the Merger in accordance with the MBCA, nothing contained in this Section 4.4
shall prohibit the Board of Directors of Seller from (i), in connection with a
Superior Competing Transaction (as defined below), furnishing information to,
or entering into discussions or negotiations with, any person that makes an
unsolicited bona fide proposal to acquire Seller pursuant to a merger,
consolidation, share exchange, business combination or other similar
transaction, if, and only to the extent that, (A) the Board of Directors of
Seller, after consultation with and taking into consideration the advice of
independent legal counsel, determines

                                     A-20



in good faith that such action is required for the Board of Directors of Seller
to comply with its fiduciary duties to shareholders imposed by Minnesota law,
(B) prior to furnishing such information to, or entering into discussions or
negotiations with, such person, Seller provides written notice to the Company
to the effect that it is furnishing information to, or entering into
discussions or negotiations with, such person, (C) prior to furnishing such
information to such person, Seller receives from such person an executed
confidentiality agreement, and (D) Seller keeps the Company informed, on a
current basis, of the status and details of any such discussions or
negotiations, or (ii) complying with Rule 14e-2 promulgated under the Exchange
Act.

   (b) For purposes of this Agreement, "Competing Proposal" shall mean any of
the following involving Seller or any Seller Subsidiary: any inquiry, proposal
or offer from any person relating to any direct or indirect acquisition or
purchase of a business that constitutes 15% or more of the net revenues, net
income or the assets of Seller and the Seller Subsidiaries taken as a whole, or
15% or more of any class of equity securities of Seller or any of the Seller
Subsidiaries, any tender offer or exchange offer that if consummated would
result in any person beneficially owning 15% or more any class of equity
securities of Seller or any of the Seller Subsidiaries, or any merger,
consolidation, business combination, recapitalization, liquidation, dissolution
or similar transaction involving Seller or any of the Seller Subsidiaries,
other than the transactions contemplated by this Agreement.

   (c) For purposes of this Agreement "Superior Competing Transaction" shall
mean any of the following involving Seller or any Seller Subsidiary: any
proposal made by a third party to acquire, directly or indirectly, including
pursuant to a tender offer, exchange offer, merger, consolidation, business
combination, recapitalization, liquidation, dissolution or similar transaction,
for consideration consisting of cash and/or securities, more than 50% of the
combined voting power of the shares of Seller Common Stock then outstanding or
all or substantially all of the assets of Seller and the Seller Subsidiaries
taken as a whole, and otherwise on terms which the Board of Directors of Seller
determines in its good faith judgment (taking into consideration the opinion of
a financial advisor of nationally recognized reputation) to be more favorable
to its shareholders than the Merger and for which financing, to the extent
required, is then committed or which if not committed is, in the good faith
judgment of its Board of Directors, reasonably capable of being obtained by
such third party.

   SECTION 4.5 Update Disclosure; Breaches.

   (a) From and after the date of this Agreement until the Effective Time,
Seller shall update the Seller Disclosure Statement on a regular basis by
written notice to the Company to reflect any matters which have occurred from
and after the date of this Agreement which, if existing on the date of this
Agreement, would have been required to be described therein; provided that (i)
to the extent that any information that would be required to be included in an
update under this Section 4.5(a) would have in the past been contained in
internal reports prepared by Seller or any Seller Subsidiary in the ordinary
course, such update may occur by delivery of such internal reports prepared in
accordance with past practice, with appropriate steps taken by Seller to
identify relevant information contained therein, and (ii) to the extent that
updating required under this Section is unduly burdensome to Seller, Seller and
the Company will use their reasonable efforts to develop alternate updating
procedures using, wherever possible, existing reporting systems.

   (b) Seller shall, in the event it becomes aware of the impending or
threatened occurrence of any event or condition which would cause or constitute
a material breach (or would have caused or constituted a material breach had
such event occurred or been known prior to the date of this Agreement) of any
of its representations or agreements contained or referred to herein, give
prompt written notice thereof to the Company and use its reasonable efforts to
prevent or promptly remedy the same.

   SECTION 4.6 Affiliates; Tax Treatment. Within thirty (30) days after the
date of this Agreement (a) Seller shall deliver to the Company a letter
identifying all persons who are then "affiliates" of Seller, including, without
limitation, all directors and executive officers of Seller, for purposes of
Rule 145 promulgated under the Securities Act (each a "Seller Affiliate") and
(b) Seller shall advise the persons identified in such letter of the resale
restrictions imposed by applicable securities laws. Seller shall use its
reasonable efforts to obtain from

                                     A-21



each person identified in such letter a written agreement, substantially in the
form attached hereto as Exhibit 4.6. Seller shall use its reasonable efforts to
obtain from any person who becomes an affiliate of Seller after Seller's
delivery of the letter referred to above, on or prior to the Effective Time, a
written agreement, substantially in the form attached hereto as Exhibit 4.6 as
soon as practicable after such person attains such status. Seller will use its
reasonable efforts to cause the Merger to qualify as a reorganization under
Section 368(a)(1)(A) of the Code.

   SECTION 4.7 Delivery of Shareholder List. Seller shall arrange to have its
transfer agent deliver to the Company or its designee, from time to time prior
to the Effective Time, a true and complete list setting forth the names and

practicable date, and such other shareholder information as the Company may
reasonably request.

   SECTION 4.8 Loan and Investment Policies. To the extent permitted by
applicable law or regulations, the Company and Seller agree to establish,
within 30 days of the date of this Agreement at Seller and any Seller
Subsidiaries which make loans, loan and investment policies and procedures
designed to insure safe and sound banking practices, which shall remain in
effect, except as otherwise agreed in writing by the Company, for the period
prior to the Effective Time. To the extent permitted by applicable law or
regulations, such policies and procedures shall apply to, among other matters,
the following: (i) making or renewing any commitments or loans, or purchase or
renewals of any participations in loans, in excess of an amount to be agreed
upon; (ii) making, committing to make or renewing any loan to any affiliate of
Seller or the Seller Subsidiaries or any family member of such affiliate or any
entity in which such affiliate has a material interest; (iii) making any
investment or commitment to invest, or making any loan, in excess of an amount
to be agreed with respect to any commercial real estate or in or with respect
to any commercial real estate development project; or (iv) entering into any
contract, lease, or license under which Seller or any Seller Subsidiary will be
bound to pay in excess of an amount to be agreed over the life of such
agreement or voluntarily committing any act or omission which constitutes a
breach or default by Seller or any Seller Subsidiary under any material
contract, lease or license to which Seller or any Seller Subsidiary is a party
or by which it or any of its properties are bound. To the extent permitted by
applicable law or regulations, the Company shall have the right to designate at
least two (2) observers to attend all meetings of Seller's (i) senior credit
committee, or similar committee at any Seller Subsidiary designated by the
Company, and (ii) investment committee or similar committee at any Seller
Subsidiary, and Seller shall ensure that such representatives receive all
information given by Seller or its agents to Seller's members of said
committees.

   SECTION 4.9 Access and Information. From the date hereof until the Effective
Time, Seller will give the Company and its representatives, employees, counsel
and accountants reasonable access to the properties, books and records of the
Seller and any other information relating to Seller that is reasonably
requested by the Company for purpose of permitting the Company, among other
things, to: (a) conduct its due diligence review, (b) review the financial
statements of Seller, (c) verify the accuracy of the representations and
warranties of Seller contained in this Agreement, (d) confirm compliance by
Seller with the terms of this Agreement, and (e) prepare for the consummation
of the transactions contemplated by the Agreement. The parties hereto
acknowledge and agree that any investigation by the Company pursuant to this
Section 4.9 shall not unreasonably interfere with the business and operations
of Seller. The Company shall not, without the consent of Seller (which consent
shall not be unreasonably withheld), contact any customers or key employees of
Seller. If the Merger contemplated hereby is not consummated, the Company shall
maintain in confidentiality all non-public and all proprietary information
acquired by the Company from the Seller in connection with its due diligence
review.

   SECTION 4.10 Confidentiality Letter. Seller agrees that the Confidentiality
Letter entered into between the Company and the Seller dated as of October 8,
2001, shall remain in full force and effect and binding upon the Seller and
shall survive termination of this Agreement.

                                     A-22

and records in accordance with accounting principles and practices as used in
the Company's financial statements applied on a consistent basis; and

   (b) conduct its business in a manner that does not violate any Law, except
for possible violations which individually or in the aggregate do not, and,
insofar as reasonably can be foreseen, in the future will not, have a Material
Adverse Effect on the Company and the Company Subsidiaries, taken as a whole.

   SECTION 5.2 Negative Covenants. Except as set forth in Section 5.2 of the
Company Disclosure Schedule or as otherwise contemplated by this Agreement,
from the date of this Agreement until the Effective Time, the Company shall
not, or agree to commit to, or permit any Company Subsidiaries to, without the
prior written consent of Seller, propose or adopt any amendments to its
Articles of Incorporation or By-laws in a manner which would adversely affect
in any manner the terms of the Company Common Stock or the ability of Company
to consummate the transactions contemplated hereby, or agree in writing to do
any of the foregoing; provided, however, that any such amendment to the Company
Articles to increase the authorized number of shares of Company Common Stock
shall not be deemed to have such an adverse effect.

   SECTION 5.3 Breaches. The Company shall, in the event it becomes aware of
the impending or threatened occurrence of any event or condition which would
cause or constitute a material breach (or would have caused or constituted a
material breach had such event occurred or been known prior to the date of this
Agreement) of any of its representations or agreements contained or referred to
herein, give prompt written notice thereof to the Seller and use its best
efforts to prevent or promptly remedy the same.

shall prepare and file with the SEC the Proxy Statement/Prospectus and

the registration with the SEC of the shares of Company Common Stock to be
issued in the Merger, and shall use all reasonable efforts to cause the

time as the shareholders of Seller

                                     A-23



shall have adopted and approved this Agreement, the Plan of Merger and the
Merger in accordance with the MBCA, withdraw, modify or change any such
recommendation to the extent the Board of Directors of Seller determines in
good faith, after consultation with and taking into consideration the advice of
independent legal counsel, that the failure to so withdraw, modify or change
its recommendation would cause the Board of Directors of Seller to breach its
fiduciary duties to Seller's shareholders under applicable Law.

   SECTION 6.2 Meeting of Seller's Shareholders. Seller shall promptly after
the date of this Agreement take all action necessary in accordance with the
MBCA and the Seller Articles and the Seller By-Laws to convene and hold the

Directors of Seller has withdrawn, modified or changed its recommendation in
favor of the Merger). Seller shall use its reasonable efforts to solicit from
shareholders of Seller proxies in favor of the Merger and approval of this
Agreement and the Plan of Merger and shall take all other action necessary or
advisable to secure the vote or consent of shareholders required by the MBCA to
approve the Merger and this Agreement and the Plan of Merger, unless the Board
of Directors of Seller shall have determined in good faith after consultation
with and taking into consideration the advice of counsel, that such actions
would violate its fiduciary duty to Seller's Shareholders under applicable Law.

   SECTION 6.3 Appropriate Action; Consents; Filings. Seller and the Company
shall use all reasonable efforts to (i) take, or cause to be taken, all
appropriate action, and do, or cause to be done, all things necessary, proper

licenses, permits, waivers, approvals, authorizations or orders required under

and local) governmental and regulatory rulings and approvals and parties to
contracts) required in connection with the authorization, execution and
delivery of this Agreement and the consummation by them of the transactions
contemplated hereby, including, without limitation, the Merger, (iii) make all
necessary filings, and thereafter make any other required submissions, with
respect to this Agreement and the Merger required under (A) the Securities Act
and the Exchange Act (to the extent applicable) and the rules and regulations
thereunder, and any other applicable federal or state securities laws, (B) the
BHCA, and any other applicable federal or state banking laws and (C) any other
applicable Law; provided that, the Company and Seller shall cooperate with each
other in connection with the making of all such filings, including providing
copies of all such documents to the non-filing party and its advisors prior to
filing and, if requested, to accept all reasonable additions, deletions or
changes suggested in connection therewith. Seller and the Company shall furnish
all information required for any application or other filing to be made
pursuant to the rules and regulations of any applicable Law (including all
information required to be included in the Proxy Statement/Prospectus and the
Registration Statement) in connection with the transactions contemplated by
this Agreement. In case at any time after the Effective Time any further action
is necessary or desirable to carry out the purposes of this Agreement, the

reasonable efforts to take all such necessary action.

agreements with respect to Seller's employee benefit matters.

   SECTION 6.5 Directors' and Officers' Indemnification and Insurance.

Seller or the Seller Subsidiaries or otherwise in effect as of the date of this

   (b) From and after the Effective Time, the Company agrees to use its
reasonable efforts to maintain an insurance policy for directors' and officers'
liabilities for all present and former directors and officers of Seller covered
by Seller's current insurance policies on the date of this Agreement; provided,
however, that the Company's obligation under this subsection (b) shall be
completely satisfied at such time as the Company shall have satisfied either of
the following conditions: (i) the Company shall have maintained an insurance
policy in accordance with this subsection (b) for a period of three years from
and after the Effective Time or (ii) the Company shall have incurred costs to
maintain insurance in accordance with this subsection equal to or exceeding

given to any exception in such representations and warranties relating to
materiality or a Material Adverse Effect, and provided, further, however, that,
for purposes of this clause, such representations and warranties shall be
deemed to be true and correct in all material respects unless the failure or
failures of such representations and warranties to be so true and correct,
individually or in the aggregate, represent a Material Adverse Effect on the

investigation before any court or administrative agency or by a government
agency or any other person (i) challenging or seeking material damages in
connection with, the Merger or the conversion of Seller Common Stock into the
Merger Consideration pursuant to the Merger or (ii) seeking to restrain,
prohibit or limit the exercise of full rights of ownership or operation by the
Company or the Company Subsidiaries of all or any portion of the business or
assets of Seller, which in either case is reasonably likely to have a Material
Adverse Effect on either Seller and the Seller Subsidiaries, taken as a whole,
or the Company and the Company Subsidiaries, taken as a whole.

   (e) Tax Opinion. An opinion of Godfrey & Kahn, S.C., independent counsel to
the Company, dated as of the Effective Time, substantially to the effect that
on the basis of facts, representations and assumptions set forth in such

Time, the Merger will be treated for federal income tax purposes as a
reorganization within the meaning of Section 368(a) of the Code, and
accordingly that no gain or loss will be recognized by Seller as a result of
the Merger. In rendering such opinion, Godfrey & Kahn may require and rely upon
representations and covenants contained in certificates of officers of the
Company, the Seller and others.

   (f) Opinion of Counsel. The Company shall have received from Maslon Edelman
Borman & Brand, or other independent counsel for Seller reasonably satisfactory

applicable to the Merger, by any federal or state governmental entity which, in
connection with the grant of any regulatory approval, imposes any condition or
restriction upon the Company or Seller or their respective subsidiaries (or the
Surviving Corporation or its subsidiaries after the Effective Time), which
would materially adversely impact the economic or business benefits of the
transactions contemplated by this Agreement in such a manner as to render
inadvisable the consummation of the Merger.

   (j) No Material Adverse Changes. Since the date of the Agreement, there has
not been any change in the financial condition, results of operations or
business of the Seller and the Seller Subsidiaries, taken as a whole, that

received a certificate of the President and the Chief Financial Officer of the
Seller to that effect.

   (k) Seller Expenses. Seller shall have delivered to the Company evidence in

investment bankers, experts and consultants to the Seller and its affiliates)

authorization, preparation and execution of this Agreement, the Registration

contemplated in this Agreement.

   (n) Retention Agreement Approval. Seller shall have obtained the approval of
its shareholders of each of the Key Executive Retention Agreements to which its
subsidiary is a party in accordance with the requirements of Q&A-7 of proposed
Treasury Regulation Section 1.280G-1. The Company shall have received a

   SECTION 7.3 Additional Conditions to Obligations of Seller. The obligation
of Seller to effect the Merger is also subject to the following conditions:

representations and warranties speak as of an earlier date) as of the Effective
Time, as though made on and as of the Effective Time; provided, however, that
for purposes of determining the satisfaction of the condition contained in this
clause, no effect shall be given to any exception in such representations and
warranties relating to materiality or a Material Adverse Effect, and provided,
further, however, that, for purposes of this clause, such representations and
warranties shall be deemed to be true and correct in all material respects
unless the failure or failures of such representations and warranties to be so
true and correct, individually or in the aggregate, represent a Material
Adverse Effect on the Company. The Seller shall have received a certificate
signed on behalf of the Company by the Chief Executive Officer and the Chief
Financial Officer of the Company to the foregoing effect.

   (b) Agreements and Covenants. The Company shall have performed or complied
in all material respects with all agreements and covenants required by this
Agreement to be performed or complied with by it on or prior to the Effective
Time.

   (c) Consents Obtained. All material consents, waivers, approvals,
authorizations or orders required to be obtained, and all filings required to
be made by the Company for the authorization, execution and delivery of this
Agreement and the consummation by it of the transactions contemplated hereby
shall have been obtained and made by the Company, except where the failure to
obtain any consents, waivers, approvals, authorizations or orders required to
be obtained or any filings required to be made would not have a Material
Adverse Effect on the Company and the Company Subsidiaries, taken as a whole.

   (d) Tax Opinion. The Seller shall have received an opinion of Maslon Edelman
Borman & Brand, in form and substance reasonably satisfactory to the Seller,
dated as of the Effective Time, substantially to the effect
   that on the basis of facts, representations and assumptions set forth in
such opinion which are consistent with the state of facts existing at the
Effective Time, the Merger will be treated as a reorganization within the
meaning of Section 368(a) of the Code, and that, accordingly, for federal
income tax purposes:

      (i) No gain or loss will be recognized by the Seller as a result of the
   Merger;

      (ii) No gain or loss will be recognized by the shareholders of the Seller
   who exchange their Seller Common Stock solely for Company Common Stock
   pursuant to the Merger (except with respect to cash received in lieu of a
   fractional share interest in Company Common Stock); and

                                     A-28



      (iii) The aggregate tax basis of the Company Common Stock received by
   shareholders who exchange their Seller Common Stock solely for Company
   Common Stock pursuant to the Merger will be the same as the aggregate tax
   basis of the Seller Common Stock surrendered in exchange therefor (reduced
   by any amount allocable to a fractional share interest for which cash is
   received).

   In rendering such opinion, the Seller's Counsel may require and rely upon
representations and covenants contained in certificates of officers of Company,
the Seller and others.

   (e) Opinion of Counsel. Seller shall have received from Godfrey & Kahn,
S.C., or other independent counsel for the Company reasonably satisfactory to
Seller, opinions dated the Effective Time, in form and substance reasonably
satisfactory to Seller, covering the matters set forth in Annex D hereto, which
opinion shall be based on such assumptions and contain such qualifications and
limitations as are appropriate and reasonably satisfactory to Seller.

   (f) No Material Adverse Changes. Since the date of the Agreement, there has
not been any change in the financial condition, results of operations or
business of the Company and the Company Subsidiaries, taken as a whole, that
either individually or in the aggregate would have a Material Adverse Effect on
the Company and the Company Subsidiaries taken as a whole. The Seller shall
have received a certificate of the President and the Chief Financial Officer of
the Company to that effect.

                ARTICLE VIII--TERMINATION, AMENDMENT AND WAIVER

      (i)  by mutual consent of the Company and Seller by a vote of majority of
   the members of the entire Board of Directors of both the Company and Seller;

      (ii) by Seller or the Company (A) if there has been a breach in any
   material respect (except that where any statement in a representation or
   warranty expressly includes a standard of materiality, such statement shall
   have been breached in any respect) of any representation, warranty, covenant
   or agreement on the part of the Company, on the one hand, or the Seller, on
   the other hand, respectively, set forth in this Agreement, or (B) if any
   representation or warranty of the Company, on the one hand, or the Seller,
   on the other hand, respectively, shall be discovered to have become untrue
   in any material respect (except that where any statement in a representation
   or warranty expressly includes a standard of materiality, such statement
   shall have become untrue in any respect), in either case which breach or
   other condition has not been cured within 30 business days following receipt
   by the nonterminating party of notice of such breach or other condition, or
   which breach by its nature, cannot be cured prior to Closing; provided,
   however, neither party shall have the right to terminate this Agreement
   pursuant to this Section 8.1(a)(ii) unless the breach of any representation
   or warranty (but not breaches of covenants or agreements), together with all
   other such breaches, would entitle the party receiving such representation
   or warranty not to consummate the transactions contemplated hereby under
   Section 7.2(a) (in the case of a breach of a representation or warranty by
   the Seller) or Section 7.3(a) (in the case of a breach of representation or
   warranty by the Company); provided, further, this Agreement may not be
   terminated pursuant to this clause (ii) by the breaching party or party
   making any representation or warranty which shall have become untrue in any

                                     A-29



      (iv) by either the Company or Seller if the Merger shall not have been
   consummated by June 30, 2002, for a reason other than the failure of the
   party seeking termination to comply with its obligations under this
   Agreement; provided that if the Merger shall not have been consummated on or
   prior to June 30, 2002 as a result of proceedings of a governmental
   authority or litigation, then the date on which either the Company or the
   Seller may terminate this Agreement under this Section 8.1(a)(iv) shall be
   extended to the earlier of (A) the lapse of a reasonable period of time
   necessary to consummate the Merger following the final termination of
   proceedings of a governmental authority or litigation or (B) September 30,
   2002;

      (v) by either the Company or Seller if the Federal Reserve Board has

      (vi) by either the Company or the Seller, if at the Seller Shareholders'
   Meeting, this Agreement, the Plan of Merger and the Merger shall fail to
   receive the requisite vote for approval and adoption by the Seller's
   Shareholders;

      (vii) by the Company, if there shall exist a proposal for a Superior
   Competing Transaction with respect to the Seller and the Board of Directors
   of the Seller has withdrawn or modified in a manner adverse to the Company
   its approval and recommendation of this Agreement or the Plan of Merger or
   its approval or recommendation of the Merger or any other transaction
   contemplated hereby or if the Board of Directors of the Seller shall have
   approved or recommended such Superior Competing Transaction; or

      (viii) by the Company if any person or persons holding of record or
   beneficially in the aggregate 5% or more of the outstanding shares of Seller
   Common Stock deliver a notice or notices of intent to demand payment in
   respect of such shares in accordance with Section 302A.473 of the MBCA.

Agreement pursuant to Section 8.1, this Agreement shall forthwith become void
and all rights and obligations of any party hereto shall cease except: (i) as
set forth in Section 9.1 of this Agreement and (ii) nothing herein shall
relieve any party from liability for any willful breach of this Agreement or
shall restrict either party's rights in the case thereof.

   SECTION 8.3 Amendment. This Agreement may be amended by the parties hereto
by action taken by or on behalf of their respective Boards of Directors at any
time prior to the Effective Time; provided, however, that, after approval this
Agreement and the Merger by the shareholders of Seller, no amendment may be
made which would reduce the amount or change the type of consideration into
which each Share shall be converted pursuant to this Agreement upon
consummation of the Merger, or which by law would require the further approval
of the shareholders of the Seller, in each case without the further approval of
the shareholders of the Seller. This Agreement may not be amended except by an
instrument in writing signed by the parties hereto.

   SECTION 8.4 Waiver. At any time prior to the Effective Time, any party
hereto may, to the extent legally allowed, (a) extend the time for the
performance of any of the obligations or other acts of the other party hereto,

herein or in any document delivered pursuant hereto and (c) waive compliance
with any of the agreements or conditions contained herein. Any such extension
or waiver shall be valid if set forth in an instrument in writing signed by the
party or parties to be bound thereby, but such extension or waiver or failure
to insist on strict compliance with an obligation, covenant, agreement or
condition shall not operate as a waiver of, or estoppel with respect to, any
subsequent other failure.

                                PLAN OF MERGER

                                    Merging

                           CENTURY BANCSHARES, INC.
                           (a Minnesota Corporation)

                                 with and into

                         MARSHALL & ILSLEY CORPORATION
                           (a Wisconsin corporation)

                                  Background

   Marshall & Ilsley Corporation, a Wisconsin corporation (the "Company"), and
Century Bancshares, Inc., a Minnesota corporation (the "Seller"), are parties
to an Agreement and Plan of Merger dated as of December 3, 2001 (the "Merger
Agreement"), providing for the merger of the Seller with and into the Company
(the "Merger") upon the terms and conditions set forth in this Plan of Merger
and pursuant to the Minnesota Business Corporation Act (the "MBCA") and the
Wisconsin Business Corporation Law (the "WBCL"). The Company and the Seller are
sometimes hereinafter together referred to as the "Constituent Corporations."
Terms used herein that are not defined herein shall have the meanings ascribed
thereto in the Merger Agreement.

                             Terms and Conditions

   1. Merger.  The Constituent Corporations shall effect the Merger upon the
terms and subject to the conditions set forth in this Plan of Merger.

   1.1 The Merger.  Upon the terms and subject to the conditions set forth in
this Plan of Merger, and in accordance with the MBCA and the WBCL, at the
Effective Time (as defined in Section 1.2) Seller shall be merged with and into
the Company. As a result of the Merger, the separate corporate existence of
Seller shall cease and the Company shall continue as the surviving corporation
of the Merger (the "Surviving Corporation").

   1.2 Effective Time.  As promptly as practicable after the satisfaction or,
if permissible, waiver of the conditions set forth in Article VII of the Merger
Agreement, the parties hereto shall cause the Merger to be consummated by
filing articles of merger (the "Articles of Merger") with the Secretary of
State of the State of Minnesota (the "Minnesota Secretary of State") and the
Department of Financial Institutions of the State of Wisconsin (the "DFI"), in
such form as required by, and executed in accordance with the relevant
provisions of, the MBCA and the WBCL (the date and time of the later of such
filing with the Minnesota Secretary of State or the DFI is referred to herein
as the "Effective Time").

   1.3 Effect of the Merger.  At the Effective Time, the effect of the Merger
shall be as provided in the Merger Agreement and the applicable provisions of
the MBCA and the WBCL. Without limiting the generality of the foregoing, and
subject thereto, at the Effective Time, except as otherwise provided herein,
all the property, rights, privileges, immunities, powers and franchises of the
Company and the Seller shall vest in the Surviving Corporation, and all debts,
liabilities and duties of the Company and the Seller shall become the debts,
liabilities and duties of the Surviving Corporation.

   1.4 Articles of Incorporation; By-Laws.  At the Effective Time, the Articles
of Incorporation, as amended, of the Company (the "Company Articles") and the
By-Laws, as amended, of the Company (the "Company By-Laws"), as in effect
immediately prior to the Effective Time, shall be the Articles of Incorporation
and the By-Laws of the Surviving Corporation.

                                      B-1



   1.5 Directors and Officers.  At the Effective Time, the directors of the
Company immediately prior to the Effective Time shall be the initial directors
of the Surviving Corporation, each to hold office in accordance with the
Articles of Incorporation and By-Laws of the Surviving Corporation and to be
assigned to the class previously assigned. At the Effective Time, the officers
of the Company immediately prior to the Effective Time, shall be the initial
officers of the Surviving Corporation, in each case until their respective
successors are duly elected or appointed.

   1.6 Merger Consideration

      (a) The aggregate dollar value of the merger consideration shall be
   $66,000,000 minus the Option Payment Amount as defined in (c) below (the
   "Merger Consideration"). The Merger Consideration shall consist of shares of
   common stock, par value $1.00 per share, of the Company ("Company Common
   Stock"); provided, however, that up to $30,000,000 minus the Option Payment
   Amount (the "Cash Amount") of the Merger Consideration may be payable in
   cash at the election of holders of the Seller Common Stock (as hereinafter
   defined). For purposes of valuing the Company Common Stock as part of the
   Merger Consideration, one share of Company Common Stock will be deemed to
   have a value equal to the average of the average high and low sale price per
   share of Company Common Stock on the New York Stock Exchange (the "NYSE") as
   reported in the Midwest Edition of The Wall Street Journal for the ten (10)
   consecutive trading days ending on and including the second trading day
   preceding the Effective Time (the "Average Trading Price"). The Company
   agrees that all of the Company's purchases of Company Common Stock shall be
   in accordance with Regulation M of the Exchange Act.

      (b) The "Per Share Merger Consideration" shall be an amount equal to the
   aggregate value of the Merger Consideration divided by the total number of
   shares of Series A common stock, $.01 par value, and Series B common stock,
   $.01 par value, of the Seller (collectively, the "Seller Common Stock")
   issued and outstanding immediately prior to the Effective Time (the
   "Outstanding Seller Common Stock").

      (c) The "Option Payment Amount" shall be an amount equal to (A) the
   number of shares of Seller Common Stock subject to options immediately prior
   to the Effective Time (such options are referred to collectively as the
   "Outstanding Options") multiplied by $7.398 (such product to be rounded to
   the nearest whole cent), minus (B) the aggregate exercise price of all
   Outstanding Options.

   1.7 Conversion of Securities; Dissenting Shares.  Subject to Section 1.7(h)
regarding fractional shares, at the Effective Time, by virtue of the Merger and
without action on the part of the Company, the Seller or the holders of the
Seller's securities:

      (a) Each share of Seller Common Stock issued and outstanding immediately
   prior to the Effective Time, other than Shares owned by the Company or any
   direct or indirect wholly owned Company Subsidiary or Seller Subsidiary for
   its own account (all such shares of Seller Common Stock issued and
   outstanding immediately prior to the Effective Time being referred to herein
   as the "Shares") and other than Dissenting Shares (as defined in Section
   1.7(j)), shall be converted into the right to receive a number of shares of
   Company Common Stock, determined by dividing the Per Share Merger
   Consideration by the Average Trading Price and rounding the result to the
   nearest one thousandth of a share (the "Stock Consideration"); provided,
   however, that, subject to the election and allocation procedures set forth
   in this Section 1.7, each holder of such Shares will be entitled, with
   respect to the Merger Consideration to be received for each such Share held
   by the holder, to elect to receive cash from the Company, without interest
   (a "Cash Election"), in an amount equal to the Per Share Merger
   Consideration (the "Cash Consideration").

      (b) The number of Shares which may be converted into the right to receive
   the Cash Consideration in the Merger shall be no more than (i) the Cash
   Amount divided by the Per Share Merger Consideration (rounded down to the
   nearest whole number) minus (ii) the total number of Dissenting Shares, if
   any (the "Cash Election Number").

      (c) If the aggregate number of Shares covered by Cash Elections (the
   "Cash Election Shares") exceeds the Cash Election Number, each Cash Election
   Share shall be converted, at the Effective Time, into the right

                                      B-2



   to receive (i) an amount in cash, without interest, equal to the product of
   (x) the Per Share Merger Consideration and (y) a fraction (the "Cash
   Fraction"), the numerator of which shall be the Cash Election Number and the
   denominator of which shall be the total number of Cash Election Shares, and
   (ii) a number of shares of Company Common Stock equal to the product of (x)
   the Stock Consideration and (y) a fraction equal to one minus the Cash
   Fraction.

      (d) In the event that Section 1.7(c) above is inapplicable, all Cash
   Election Shares shall be converted, at the Effective Time, into the right to
   receive the Cash Consideration and all other Shares, other than Dissenting
   Shares, shall be converted, at the Effective Time, into the right to receive
   the Stock Consideration.

      (e) All Cash Elections shall be made on a form designed for that purpose
   and mutually acceptable to the Company and Seller (a "Form of Election") and
   mailed to holders of record of Shares as of the record date for the Seller
   Shareholders' Meeting or such other date as the Company and the Seller shall
   mutually agree (the "Election Form Record Date"). The Company and the Seller
   shall make available one or more Election Forms as may be reasonably
   requested by all persons who become holders of record of Shares between the
   Election Form Record Date and the Election Deadline (as defined below).
   Elections shall be made by submitting to the Exchange Agent (as defined
   below) a duly completed Form of Election. To be effective, a Form of
   Election must be properly completed, signed and submitted to the Exchange
   Agent in accordance with Section 1.7(f). The Company will have the
   discretion, which it may delegate in whole or in part to the Exchange Agent,
   to reasonably determine whether Forms of Election have been properly
   completed, signed and submitted or revoked and to disregard immaterial
   defects in Forms of Election. The decision of the Company (or the Exchange
   Agent) shall be conclusive and binding. Neither the Company nor the Exchange
   Agent will be under any obligation to notify any person of any defect in a
   Form of Election submitted to the Exchange Agent. The Exchange Agent shall
   also make all computations contemplated by this Section 1.7 and all
   computations shall be conclusive and binding on the holders of Shares.

      (f) A Form of Election must be received by the Exchange Agent by the
   close of business of the last business day prior to the date of the Seller
   Shareholders' Meeting in order to be effective. Such time on such date shall
   hereinafter be referred to as the "Election Deadline." Any holder of Shares
   who has made an election may at any time prior to the Election Deadline
   change or withdraw its election by written notice to the Exchange Agent
   prior to the Election Deadline. As soon as practicable after the Election
   Deadline, the Exchange Agent shall determine the allocation of the cash
   portion of the Merger Consideration and the stock portion of the Merger
   Consideration and shall notify the Company of its determination.

      (g) The Shares of a holder who does not submit a Form of Election which
   is received by the Exchange Agent prior to the Election Deadline (other than
   Dissenting Shares) shall be converted into the right to receive the Stock
   Consideration at the Effective Time. If the Company or the Exchange Agent
   shall determine that any purported Cash Election was not properly made, the
   purported Cash Election shall be deemed to be of no force and effect and the
   Shares of the holder making such purported Cash Election shall be converted
   into the right to receive the Stock Consideration at the Effective Time.

      (h) No fractional shares of Company Common Stock shall be issued in the
   Merger. All fractional shares of Company Common Stock that a holder of any
   Shares would otherwise be entitled to receive as a result of the Merger
   shall be aggregated. If a fractional share of Company Common Stock results
   from the aggregation, the holder shall be entitled to receive, in lieu
   thereof, a cash amount, without interest, determined by multiplying the
   Average Trading Price by the fraction of a share of Company Common Stock to
   which the holder would otherwise have been entitled. As promptly as
   practicable after the determination of the amount of cash, if any, to be
   paid to holders of fractional share interests, the Exchange Agent shall so
   notify the Company, and the Company shall deposit that amount with the
   Exchange Agent and shall cause the Exchange Agent to forward payments to the
   holders of fractional share interests, subject to and in accordance with the
   terms of this Section 1.7.

                                      B-3



      (i) Each share of Seller Common Stock held by the Company or any direct
   or indirect wholly owned Company Subsidiary or Seller Subsidiary for its own
   account shall be canceled and extinguished at the Effective Time without
   conversion thereof into the Merger Consideration or payment therefor.

      (j) Notwithstanding anything in this Plan of Merger to the contrary,
   shares of Seller Common Stock which are issued and outstanding immediately
   prior to the Effective Time and which are held by shareholders or beneficial
   owners who have validly exercised and perfected dissenter's rights with
   respect to those Shares under Sections 302A.471 and 302A.473 of the MBCA and
   have not withdrawn or lost such rights (the "Dissenting Shares") shall not
   be converted into or be exchangeable for the right to receive the Merger
   Consideration in accordance with this Section 1.7, unless and until such
   holders or beneficial owners shall have failed to perfect or shall have
   effectively withdrawn or lost their dissenter's rights with respect to such
   Dissenting Shares under the MBCA. Dissenting Shares shall be treated in
   accordance with Sections 302A.471 and 302A.473 of the MBCA, if and to the
   extent applicable. If, after the Effective Time, any such holder or
   beneficial owner shall have failed to perfect or shall have effectively
   withdrawn or lost such right to dissent with respect to any Dissenting
   Shares, such Dissenting Shares shall thereupon be treated as if they had
   been converted into and become exchangeable only for the right to receive,
   as of the Effective Time, the Stock Consideration in accordance with this
   Section 1.7, without any interest thereon. Seller shall give the Company (a)
   prompt notice of each and every notice of a shareholder's or beneficial
   owner's intent to demand payment of the "fair value" of the shareholder's or
   beneficial owner's Shares, attempted withdrawals of such demands, and any
   other instruments served pursuant to the MBCA and received by the Seller
   relating to rights to be paid the "fair value" of Shares, as provided in
   Sections 302A.471 and 302A.473 of the MBCA and (b) the opportunity to direct
   all negotiations and proceedings with respect to such demands for "fair
   value." Seller shall not, except with the prior written consent of the
   Company, voluntarily make any payment with respect to, offer to settle or
   settle, or approve any withdrawal of any such demands for "fair value."

      (k) Each option to purchase shares of Seller Common Stock (each, a
   "Seller Option") outstanding under any stock option plan immediately prior
   to the Effective Time, whether or not vested or exercisable, shall be
   converted into the right to receive cash from the Company in an amount equal
   to (A) the number of shares of Seller Common Stock subject to such Seller
   Option multiplied by (B) $7.398 (the product of (A) and (B) shall be rounded
   to the nearest whole cent), minus (C) the aggregate exercise price for such
   Seller Option. After the Effective Time, each Seller Option shall represent
   only the right to receive the cash amount described above and shall not
   represent a right to receive any securities of the Company.

   1.8 Exchange of Certificates.

      (a) Exchange Agent.  The Company shall deposit, or shall cause to be
   deposited, from time to time, with a bank or trust company designated by the
   Company and which may be an affiliate of the Company (the "Exchange Agent"),
   for the benefit of the holders of Shares, for exchange in accordance with
   this Section 1, through the Exchange Agent, the Merger Consideration,
   together with any dividends or distributions with respect thereto, if any,
   to be paid in respect of Shares pursuant to this Section 1 (the "Exchange
   Fund"). Such deposits shall be made after the Effective Time as requested by
   the Exchange Agent in order for the Exchange Agent to promptly deliver the
   Merger Consideration.

      (b) Exchange Procedures.  As soon as reasonably practicable after the
   Effective Time, the Exchange Agent shall mail to each holder of record of a
   certificate representing Shares which were converted into the right to
   receive the Merger Consideration pursuant to Section 1.7 (each, a
   "Certificate" and collectively, the "Certificates"), (i) a letter of
   transmittal (which shall specify that delivery shall be effected, and risk
   of loss and title to the Certificates shall pass, only upon delivery of the
   Certificates to the Exchange Agent and shall be in such form and have such
   other provisions as the Company may reasonably specify) and (ii)
   instructions for use in effecting the surrender of the Certificates in
   exchange for the Merger Consideration. Upon surrender of a Certificate for
   cancellation to the Exchange Agent together with such letter of transmittal,
   duly executed, the holder of such Certificate shall be entitled to receive
   in exchange therefor the Merger Consideration and any unpaid dividends and
   distributions thereon as provided in this Section 1,

                                      B-4



   which such holder has the right to receive in respect of the Certificate
   surrendered pursuant to the provisions of this Section 1, and the
   Certificate so surrendered shall forthwith be canceled. In the event of a
   transfer of ownership of Shares which is not registered in the transfer
   records of the Seller, a transferee may exchange the Certificate
   representing such Shares for the Merger Consideration and any unpaid
   dividends and distributions thereon as provided in this Section 1 if the
   Certificate representing such Shares is presented to the Exchange Agent,
   accompanied by all documents required to evidence and effect such transfer
   and by evidence that any applicable stock transfer taxes have been paid. In
   the event any Certificate shall have been lost, stolen or destroyed, upon
   the making of an affidavit of that fact by the person claiming such
   Certificate to be lost, stolen or destroyed and the posting by such person
   of a bond in such amount as the Company may direct as indemnity against any
   claim that may be made against it or the Exchange Agent with respect to such
   Certificate, the Exchange Agent will issue in exchange for such lost, stolen
   or destroyed Certificate the Merger Consideration and any unpaid dividends
   and distributions thereon as provided in this Section 1, which such holder
   would have had the right to receive in respect of such lost, stolen or
   destroyed Certificate. Until surrendered as contemplated by this Section
   1.8, each Certificate shall be deemed at any time after the Effective Time
   to represent only the right to receive upon such surrender the Merger
   Consideration and any unpaid dividends and distributions thereon as provided
   in this Section 1.

      (c) Distributions with Respect to Unexchanged Shares. No dividends or
   other distributions declared or made after the Effective Time with respect
   to Company Common Stock with a record date after the Effective Time shall be
   paid to the holder of any unsurrendered Certificate with respect to the
   shares of Company Common Stock issuable in exchange for the Shares
   represented thereby, and no cash payment in lieu of fractional shares shall
   be paid to any such holder pursuant to Section 1.7(h), until the holder of
   such Certificate shall surrender such Certificate. Subject to the effect of
   applicable laws, following surrender of any such Certificate, there shall be
   paid to the holder of the certificates representing whole shares of Company
   Common Stock issued in exchange therefor, without interest, (i) promptly,
   the amount of any cash payable with respect to a fractional share of Company
   Common Stock to which such holder is entitled pursuant to Section 1.7(h) and
   the amount of dividends or other distributions with a record date after the
   Effective Time theretofore paid with respect to such whole shares of Company
   Common Stock, and (ii) at the appropriate payment date, the amount of
   dividends or other distributions, with a record date after the Effective
   Time but prior to surrender and a payment date occurring after surrender,
   payable with respect to such whole shares of Company Common Stock.

      (d) No Further Rights in the Shares. All Merger Consideration issued or
   paid upon conversion of the Shares in accordance with the terms hereof
   (including any cash paid pursuant to Section 1.7(h)) shall be deemed to have
   been issued or paid in full satisfaction of all rights pertaining to such
   Shares.

      (e) Termination of Exchange Fund. Any portion of the Exchange Fund which
   remains undistributed to the former shareholders of Seller for six (6)
   months after the Effective Time shall be delivered to the Company, upon
   demand, and any former shareholders of Seller who have not theretofore
   complied with this Section 1 shall thereafter look only to the Company to
   claim the Merger Consideration to which they are entitled, any cash in lieu
   of fractional shares of Company Common Stock and any dividends or
   distributions with respect to Company Common Stock, in each case without
   interest thereon, and subject to Section 1.8(f).

      (f) No Liability. Neither the Company nor the Seller shall be liable to
   any former holder of Shares for any shares of Company Common Stock (or
   dividends or distributions with respect thereto) or cash or other payment
   delivered to a public official pursuant to any abandoned property, escheat
   or similar laws.

      (g) Withholding Rights. The Company shall be entitled to deduct and
   withhold from the consideration otherwise payable pursuant to this Plan of
   Merger to any former holder of Shares or any holder of Seller Options such
   amounts as the Company is required to deduct and withhold with respect to
   the making of such payment under the Code, or any provision of state, local
   or foreign tax law. To the extent that amounts are so withheld by the
   Company, such withheld amounts shall be treated for all purposes of this
   Plan of Merger as having been paid to the former holder of the Shares or the
   former holder of Seller Options, as the case may be, in respect of which
   such deduction and withholding was made by the Company.

                                      B-5



   1.9 Stock Transfer Books.  At the Effective Time, the stock transfer books
of Seller shall be closed and there shall be no further registration of
transfers of shares of Seller Common Stock thereafter on the records of Seller.
From and after the Effective Time, the holders of certificates evidencing
ownership of shares of Seller Common Stock outstanding immediately prior to the
Effective Time shall cease to have any rights with respect to such Shares
except as otherwise provided herein or by law. On or after the Effective Time,
any Certificates presented to the Exchange Agent or the Company for any reason
shall be converted into the Merger Consideration in accordance with this
Section 1.

   1.10 Adjustments for Dilution and Other Matters.  If, after the date of the
Merger Agreement and during the period in which the Average Trading Price is
determined, the Company shall declare a stock dividend or distribution upon or
subdivide, split up, reclassify or combine the Company Common Stock or declare
a dividend or make a distribution on the Company Common Stock in any security
convertible into Company Common Stock, appropriate adjustment or adjustments,
if any, will be made to the Merger Consideration and the Stock Consideration
determined pursuant to Sections 1.6(a) and 1.7(a).

   1.11 Company Common Stock.  The shares of Company Common Stock issued and
outstanding immediately prior to the Effective Time shall be unaffected by the
Merger and at the Effective Time, such shares shall remain issued and
outstanding.

   2. Termination.  This Plan of Merger may be terminated at any time on or
before the Effective Time by agreement of the Boards of Directors of the
Constituent Corporations. This Plan of Merger shall be automatically terminated
if the Merger Agreement is terminated in accordance with the terms thereof.

   302A.471 RIGHTS OF DISSENTING SHAREHOLDERS.--Subdivision 1. Actions creating
rights. A shareholder of a corporation may dissent from, and obtain payment for
the fair value of the shareholder's shares in the event of, any of the
following corporate actions:

   (a) An amendment of the articles that materially and adversely affects the
rights or preferences of the shares of the dissenting shareholder in that it:

   series with similar or different voting rights; excepts that an amendment to
   the articles of an issuing public corporation that provides that section
   302A.671 does not apply to a control share acquisition does not give rise to
   the right to obtain payment under this section;

   (b) A sale, lease, transfer, or other disposition of all or substantially
all of the property and assets of the corporation, but not including a
transaction permitted without shareholder approval in section 302A.661,

respect to which the articles, the bylaws, or a resolution approved by the
board directs that dissenting shareholders may obtain payment for their shares.

   (a) A shareholder shall not assert dissenters' rights as to less than all of
the shares registered in the name of the shareholder, unless the shareholder
dissents with respect to all the shares that are beneficially owned by another
person but registered in the name of the shareholder and discloses the name and
address of each beneficial owner on whose behalf the shareholder dissents. In
that event, the rights of the dissenter shall be determined as if the shares as
to which the shareholder has dissented and the other shares were registered in
the names of different shareholders.

                                      C-1



   (b) A beneficial owner of shares who is not the shareholder may assert
dissenters' rights with respect to shares held on behalf of the beneficial
owner, and shall be treated as a dissenting shareholder under the terms of this
section and section 302A.473, if the beneficial owner submits to the
corporation at the time of or before the assertion of the rights a written
consent of the shareholder.

   Subdivision 3. Rights not to apply.

   (a) Unless the articles, the bylaws, or a resolution approved by the board
otherwise provide, the right to obtain payment under this section does not
apply to a shareholder of (1) the surviving corporation in a merger with
respect to shares of the shareholder that are not entitled to be voted on the
merger and are not canceled or exchanged in the merger or (2) the corporation
whose shares will be acquired by the acquiring corporation in a plan of
exchange with respect to shares of the shareholder that are not entitled to be
voted on the plan of exchange and are not exchanged in the plan of exchange.

   (b) If a date is fixed according to section 302A.445, subdivision 1, for the
determination of shareholders entitled to receive notice of and to vote on an
action described in subdivision 1, only shareholders as of the date fixed, and
beneficial owners as of the date fixed who hold through shareholders, as
provided in subdivision 2, may exercise dissenters' rights.

   Subdivision 4. Other rights. The shareholders of a corporation who have a
right under this section to obtain payment for their shares do not have a right
at law or in equity to have a corporate action described in subdivision 1 set
aside or rescinded, except when the corporate action is fraudulent with regard
to the complaining shareholder or the corporation. (Last amended by Ch. 264, L.
'00, eff. 8-1-00.)

   302A.473 PROCEDURES FOR ASSERTING DISSENTERS' RIGHTS.--Subdivision 1.
Definitions.

   (a) For purposes of this section, the terms defined in this subdivision have
the meanings given them.

   (b) "Corporation" means the issuer of the shares held by a dissenter before
the corporate action referred to in section 302A.471, subdivision 1 or the
successor by merger of that issuer.

   (c) "Fair value of the shares" means the value of the shares of a
corporation immediately before the effective date of the corporate action
referred to in section 302A.471, subdivision 1.

   (d) "Interest" means interest commencing five days after the effective date
of the corporate action referred to in section 302A.471, subdivision 1, up to
and including the date of payment, calculated at the rate provided in Section
549.09 for interest on verdicts and judgments.

   Subdivision 2. Notice of action. If a corporation calls a shareholder
meeting at which any action described in section 302A.471, subdivision 1 is to
be voted upon, the notice of the meeting shall inform each shareholder of the
right to dissent and shall include a copy of Section 302A.471 and this section
and a brief description of the procedure to be followed under these sections.

   Subdivision 3. Notice of dissent. If the proposed action must be approved by
the shareholders, a shareholder who is entitled to dissent under Section
302A.471 and who wishes to exercise dissenters' rights must file with the
corporation before the vote on the proposed action a written notice of intent
to demand the fair value of the shares owned by the shareholder and must not
vote the shares in favor of the proposed action.

   Subdivision 4. Notice of procedure; deposit of shares.

   (a) After the proposed action has been approved by the board and, if
necessary, the shareholders, the corporation shall send to all shareholders who
have complied with subdivision 3 and to all shareholders entitled to dissent if
no shareholder vote was required, a notice that contains:

                                      C-2



      (1) the address to which a demand for payment and certificates of
   certificated shares must be sent in order to obtain payment and the date by
   which they must be received;

      (2) any restrictions on transfer of uncertificated shares that will apply
   after the demand for payment is received;

      (3) a form to be used to certify the date on which the shareholder, or
   the beneficial owner on whose behalf the shareholder dissents, acquired the
   shares or an interest in them and to demand payment; and

      (4) a copy of section 302A.471 and this section and a brief description
   of the procedures to be followed under these sections.

   (b) In order to receive the fair value of the shares, a dissenting
shareholder must demand payment and deposit certificated shares or comply with
any restrictions on transfer of uncertificated shares within 30 days after the
notice required by paragraph (a) was given, but the dissenter retains all other
rights of a shareholder until the proposed action takes effect.

   Subdivision 5. Payment; return of shares.

   (a) After the corporate action takes effect, or after the corporation
receives a valid demand for payment, whichever is later, the corporation shall
remit to each dissenting shareholder who has complied with subdivisions 3 and 4
the amount the corporation estimates to be the fair value of the shares, plus
interest, accompanied by:


      (1) the corporation's closing balance sheet and statement of income for a
   fiscal year ending not more than 16 months before the effective date of the
   corporate action, together with the latest available interim financial
   statements;

      (2) an estimate by the corporation of the fair value of the shares and a
   brief description of the method used to reach the estimate; and

      (3) a copy of section 302A.471 and this section, and a brief description
   of the procedure to be followed in demanding supplemental payment.

   (b) The corporation may withhold the remittance described in paragraph (a)
from a person who was not a shareholder on the date the action dissented from
was first announced to the public or who is dissenting on behalf of a person
who was not a beneficial owner on that date. If the dissenter has complied with
subdivisions 3 and 4, the corporation shall forward to the dissenter the
materials described in paragraph (a), a statement of the reason for withholding
the remittance, and an offer to pay to the dissenter the amount listed in the
materials if the dissenter agrees to accept that amount in full satisfaction.
The dissenter may decline the offer and demand payment under subdivision 6.
Failure to do so entitles the dissenter only to the amount offered. If the
dissenter makes demand, subdivisions 7 and 8 apply.

   (c) If the corporation fails to remit payment within 60 days of the deposit
of certificates or the imposition of transfer restrictions on uncertificated
shares, it shall return all deposited certificates and cancel all transfer
restrictions. However, the corporation may again give notice under subdivision
4 and require deposit or restrict transfer at a later time.

   Subdivision 6. Supplemental payment; demand. If a dissenter believes that
the amount remitted under subdivision 5 is less than the fair value of the
shares plus interest, the dissenter may give written notice to the corporation
of the dissenter's own estimate of the fair value of the shares, plus interest,
within 30 days after the corporation mails the remittance under subdivision 5,
and demand payment of the difference. Otherwise, a dissenter is entitled only
to the amount remitted by the corporation.

   Subdivision 7. Petition; determination. If the corporation receives a demand
under subdivision 6, it shall, within 60 days after receiving the demand,
either pay to the dissenter the amount demanded or agreed to by the

                                      C-3



dissenter after discussion with the corporation or file in court a petition
requesting that the court determine the fair value of the shares, plus
interest. The petition shall be filed in the county in which the registered
office of the corporation is located, except that a surviving foreign
corporation that receives a demand relating to the shares of a constituent
domestic corporation shall file the petition in the county in this state in
which the last registered office of the constituent corporation was located.
The petition shall name as parties all dissenters who have demanded payment
under subdivision 6 and who have not reached agreement with the corporation.
The corporation shall, after filing the petition, serve all parties with a
summons and copy of the petition under the rules of civil procedure.
Nonresidents of this state may be served by registered or certified mail or by
publication as provided by law. Except as otherwise provided, the rules of
civil procedure apply to this proceeding. The jurisdiction of the court is
plenary and exclusive. The court may appoint appraisers, with powers and
authorities the court deems proper, to receive evidence on and recommend the
amount of the fair value of the shares. The court shall determine whether the
shareholder or shareholders in question have fully complied with the
requirements of this section, and shall determine the fair value of the shares,
taking into account any and all factors the court finds relevant, computed by
any method or combination of methods that the court, in its discretion, sees
fit to use, whether or not used by the corporation or by a dissenter. The fair
value of the shares as determined by the court is binding on all shareholders,
wherever located. A dissenter is entitled to judgment in cash for the amount by
which the fair value of the shares as determined by the court, plus interest,
exceeds the amount, if any, remitted under subdivision 5, but shall not be
liable to the corporation for the amount, if any, by which the amount, if any,
remitted to the dissenter under subdivision 5 exceeds the fair value of the
shares as determined by the court, plus interest.

   Subdivision 8. Costs; fees; expenses.

   (a) The court shall determine the costs and expenses of a proceeding under
subdivision 7, including the reasonable expenses and compensation of any
appraisers appointed by the court, and shall assess those costs and expenses
against the corporation, except that the court may assess part or all of those
costs and expenses against a dissenter whose action in demanding payment under
subdivision 6 is found to be arbitrary, vexatious, or not in good faith.

   (b) If the court finds that the corporation has failed to comply
substantially with this section, the court may assess all fees and expenses of
any experts or attorneys as the court deems equitable. These fees and expenses
may also be assessed against a person who has acted arbitrarily, vexatiously,
or not in good faith in bringing the proceeding, and may be awarded to a party
injured by those actions.

   (c) The court may award, in its discretion, fees and expenses to an attorney
for the dissenters out of the amount awarded to the dissenters, if any. (Last
amended by Ch. 10, L. '97, eff. 8-1-97.)

                   CENTURY BANCSHARES, INC. AND SUBSIDIARIES

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
                            SELECTED FINANCIAL DATA

Changes in Financial Condition

   Total Century Bancshares, Inc. and subsidiaries (the Company) assets at year
end 2000 were $278,050,000. During 2000, assets increased by $49,448,000 or
21.6%. The majority of this increase was in gross loans, which increased by
$46,730,000 or 24.8% to $235,207,000. The loan growth experienced was primarily
due to increased commercial and commercial real estate loan activity within the
Minneapolis metropolitan market.

   Most of the increased loan balances were funded by an increase in total
deposits. Total deposits increased from $200,318,000 at December 31, 1999 to
$238,956,000 at December 31, 2000, an increase of $38,638,000, or 19.3%. The
majority of the deposit growth was in additional certificates of deposits
within the Company's Minneapolis metropolitan market area. There was also an
increase in brokered certificates of deposit and Federal Home Loan Bank term
notes. In order to meet the record loan demand, the Company needed to rely more
heavily on non-core deposit funding throughout the year. These sources of funds
however, remain at less than 10% of total assets. The Company refinanced its
note payable and borrowed an additional $665,000 through this financing.

   Stockholders' equity increased by $3,757,000 or 19.2% in 2000. This increase
resulted from Company net income of $3,970,000 and a $372,000 increase in
unrealized gains on securities available-for-sale. The Company also redeemed
shares of stock held by a former employee. No dividends were declared or paid.

   Total securities increased by $4,891,000 in 2000. Cash and cash equivalents
combined with federal funds sold decreased by $619,000 in 2000.

   During the period from December 31, 2000 to September 30, 2001, total assets
grew by $64,540,000, an increase of 23.2%; a significant portion of this
increase was in the purchase of a non-bank subsidiary, Spectrum Commercial
Services Company (Spectrum). Spectrum is an asset based lending company with
total assets as of September 30, 2001 of $20,154,000. On October 31, 2001, the
Company sold its interest in Spectrum to an investor group comprised of certain
officers and directors of the Company for an amount approximating carrying
value.

   In addition to the purchase of Spectrum, loan balances at the Company's
subsidiary bank grew by $22,672,000 or 9.6% during the nine-month period.

   In September 2001, the Company sold its 60 percent limited partnership
interest in Century Bank Building Partnership to certain officers of the
Company. The sales price was based on the appraised fair value of the building
less existing debt in the partnership and resulted in a gain to the Company of
approximately $1,271,000, of which, approximately $338,000 was deferred. The
Bank's lease with the building partnership was substantially unchanged.

   Total deposits increased by $36,223,000, or 15.2% during the period from
December 31, 2000 to September 30, 2001. The Company continued its efforts to
expand depository relationships with its existing customer base. In addition,
several new larger account relationships were initiated within the Twin Cities
market. The growth in deposit balances was balanced in mix between the
following deposit accounts: demand deposits and NOW accounts grew by
$11,465,000, money market savings grew by $11,823,000 and certificates of
deposits grew by $12,935,000.

   Notes payable increased $27,612,000 during the nine months ended September
30, 2001. The increase is comprised of $10,000,000 in FHLB advances at the
subsidiary bank, $2,000,000 to fund the purchase of Spectrum, and $15,000,000
in borrowings at Spectrum to fund its asset based lending activities.

   Stockholders' equity increased by $4,208,000 from December 31, 2000 to
September 30, 2001. The increase came from $3,911,000 of net income and the
remainder from the change in unrealized gains on available-for-sale securities.
No dividends were declared or paid.

                                      D-1



Results of Operations for the Nine Months Ended September 30, 2001 Compared
with the Nine Months Ended September 30, 2000

   For the nine months ended September 30, 2001, the Company's net income
increased by $808,000 or 26.0% over the same nine-month period in 2000. As
discussed in further detail below, the increase primarily resulted from
increased net interest income of $1,004,000 and a gain on sale of the limited
partnership of $933,000.

   Net interest income increased by $1,004,000, or 9.7%, to $11,308,000. While
the Company's net interest margin declined to 5.16% from 5.81% for the nine
month period ended September 30, 2001 and 2000, respectively, the primary
component of this decrease was a drop in the prime lending rate of 350 basis
points, an increase in volume of earning assets more than offset this decline.
Another factor contributing to the decline in net interest margin is the
increase in notes payable as a percentage of interest bearing liabilities.

   The balance in the allowance for loan losses is based on management's
evaluation of the loan portfolio. Management determines the adequacy of the
allowance for loan losses based on past loan loss experience, current economic
conditions, and composition of the loan portfolio and the potential for future
loss. During the nine month period ended September 30, 2001, there were $21,700
less in net charge-offs compared with the same period in 2000. As a result of
this and due to an increase in the quality of the loan portfolio, the provision
for loan losses decreased by $199,000 to $360,000 for the nine month period
ended September 30, 2001 compared to this same period in 2000. Management
believes the reserve is adequate to absorb estimated losses in the loan
portfolio. The loan loss reserve to total loans was 1.57% as of September 30,
2001.

   Other income increased by $1,999,000, or 164% for the first nine months of
2001 compared to the first nine months of 2000. The increase was primarily due
to the gain on sale of the limited partnership interest of $933,000. Also, the
addition of our non bank subsidiary, Spectrum contributed $776,000 in other
income for the period ending September 30, 2001. There was also an increase of
$200,000 in service release premiums and other fees related to Century Bank's
mortgage department.

   Operating expenses increased from $5,975,000 to $7,865,000, an increase of
$1,890,000, or 32% for the first nine months of 2001 compared to the same
period in 2000. This increase was primarily related to the addition of
Spectrum, whose total operating expenses were $1,272,000 for the first nine
months of 2001, and a $469,000 increase in salaries and benefits at the
subsidiary bank.

   Income tax expense increased by $503,000 in the first nine months of 2001
compared with the same period in 2000 due to an increase of approximately
$1,312,000 in pre-tax income. The effective tax rate was approximately 38%
during both periods.

Results of Operations for the Years Ended December 31, 2000, 1999 and 1998

   Net income in 2000 totaled $3,969,000, an increase of $745,000 or 23.1% over
the $3,224,000 earned in 1999. Net income in 1999 was $762,000 or 31.0% over
the 1998 level of $2,462,000. The growth in net income was due largely to the
growth in assets of the Company's subsidiary bank, increased loan fees and
improved operating efficiency. At December 31, 2000, 1999 and 1998, the total
assets per employee were approximately $3.4 million, $3.0 million and $3.0
million, respectively.

   Net interest income increased $2,616,000, or 22.8% to $14,084,000 in 2000
compared to $11,468,000 in 1999. The 1999 total represented an increase of
$1,162,000, or 11.3% compared to 1998. The net interest margin for 2000 was
5.86% compared with 6.11% in 1999 and 5.68% in 1998. The margin has been
compressed during the past year as a result of increasing competitive
pressures. Loan yields increased by 73 basis points from 1999 compared to 2000,
however, competitive pressures caused the effective rate paid on deposits to
increase 95 basis points from 4.09% in 1999 to 5.04% in 2000. From 1998 to
1999, the yield on earning assets increased by 28 basis points, from 8.77% in
1998 to 9.05% in 1999. There was also a reduction in the cost of deposits by 55
basis points. The level of year to date average earning assets increased by
$4.7 million from 1998 to 1999 and by $54.7 million from 1999 to 2000.

                                      D-2



   The provision for loan losses was $1,053,000 for 2000, representing an
increase of $559,000 or 113.2% over the $494,000 of loss provision charged to
operations in 1999. The 1999 provision was $159,000 or 24.4% less than the
provision of $653,000 incurred in 1998. Net charge-off activity has been
minimal in comparison to total outstanding loans in all of the three comparison
years. The percentage of the allowances for loan losses to total gross loans
outstanding decreased from 1.50% to 1.47% from 1998 to 1999. The percentage of
the allowances for loan losses to total gross loans outstanding increased from
1.47% to 1.59% from 1999 to 2000 due to an increase in credit risk and
provisions made to loan loss reserve totaling $1,053,000.

   Other income consists primarily of deposit account service charges, related
fee income, and the equity in earnings of the limited partnership. Other income
increased by $441,000 or 42.3% in 2000 compared to 1999 and by $17,000 or 1.6%
in 1999 compared to 1998. Increases in deposit volume attribute to this
increase in fee income.

   Other expenses increased $1,341,000 or 19.6% in 2000 compared to a $110,000
or 1.6% increase in 1999 over 1998 levels. Salary and related benefit expenses
increased by $885,000 or 22.4% in 2000 due to an increase in the number of full
time equivalent employees and also to an increase in base compensation and
individual performance incentives. Salary and benefits decreased by $78,000 or
1.9% from 1998 to 1999. Occupancy expenses increased $153,000 in 2000 and
$237,000 in 1999 primarily due to increases in office space under lease in the
Eden Prairie location.

   Income tax expense increased by $412,000 or 21.0% from 1999 to 2000 while
the increase from 1998 to 1999 was $466,000 or 31.1%. The effective income tax
rates approximated 38% during each of these years.

Liquidity and Capital Resources

   The concept of liquidity comprises the ability of an enterprise to maintain
sufficient cash flow to meet its needs and obligations on a timely basis. Bank
liquidity must be considered in terms of the nature and mix of the
institution's sources and uses of funds. Bank liquidity is provided from
several asset categories. The asset side of the balance sheet provides
liquidity through maturities of investment securities and repayment of loans.
Cash and amounts due from correspondent banks, investment securities available
for sale and Federal funds sold are primarily sources of asset liquidity. At
December 31, 2000, these categories totaled approximately $39.0 million; these
categories totaled approximately $62.6 million at September 30, 2001.

   The Company has no significant plans for major capital expenditures in 2002.

   Management believes that, in the current economic environment, the Bank's
liquidity position is adequate. There are no known trends, nor any known
demands, commitments, events or uncertainties that will result or are
reasonably likely to result in a material increase or decrease in the Bank's
liquidity.

Effects of Inflation

   The Company's consolidated financial statements and notes thereto have been
prepared in accordance with generally accepted accounting principles, which
require the measurement of financial position and operating results in terms of
historical dollars without considering the changes in the relative purchasing
power of money over time due to inflation. The impact of inflation is reflected
in the increased cost of the Company's operations. Unlike most industrial
companies, nearly all of the assets and liabilities of the Company are monetary
in nature. As a result, interest rates have a greater impact on the Company's
performance than do the effects of general levels of inflation. Interest rates
do not necessarily move in the same direction or to the same extent as the
price of goods and services.

Regulatory Capital Requirements

   The Federal Reserve Board, the Company's primary regulator, has adopted
risk-based capital regulations, which require the Company to maintain certain
risk based capital/asset ratios. The Company's capital ratios and those of the
Bank exceed the minimum ratios required by their respective regulators. The
Office of the Comptroller of Currency (OCC) examines and regulates the Bank.
Management is not aware of any pending regulatory requirements or
recommendations that, if enacted, would have a material adverse impact on the
Company's capital, liquidity, or results of operations.

Note 1.  Summary of Significant Accounting Policies

   Nature of business:  Century Bancshares, Inc., is a bank holding company.
Its wholly owned subsidiary, Century Bank, National Association (Bank), is a
commercial bank with branch operations in Eden Prairie, St. Louis Park, and
Coon Rapids, Minnesota. The Bank provides retail and commercial loan and
deposit services principally to customers within the Minneapolis-St. Paul
metropolitan area. Century Bancshares, Inc., purchased a 99 percent interest in
Spectrum Commercial Services Company (Spectrum) in March 2001. Spectrum
provides asset-based lending and factoring services to small to medium-sized
businesses. The acquisition of Spectrum has been accounted for as a purchase,
and results of operations of Spectrum since the date of acquisition have been
included in the consolidated financial statements (see also Note 4).

   Basis of financial statement presentation:  The accompanying unaudited
interim consolidated financial statements have been prepared in accordance with
accounting principles generally accepted in the United States of America for
interim financial information. Accordingly, they do not include all information
and disclosures required by generally accepted accounting principles for
complete financial statements. The accompanying condensed consolidated
financial statements do not purport to contain all the necessary financial
disclosures required by generally accepted accounting principles that might
otherwise be necessary in the circumstances.

   In the opinion of management, all adjustments (consisting of normal
recurring accruals) considered necessary for fair presentations have been
included. The results of operations for the nine-month periods ended September
30, 2001 and 2000, are not necessarily indicative of the results that may be
expected for the entire fiscal years or any other interim periods.

Note 2.  Comprehensive Income

available-for-sale securities, net of related deferred income taxes, the change
in which is as follows:

Note 3.  Century Bank Building Partnership

   In September 2001, the Company sold its 60 percent limited partnership
interest in Century Bank Building Partnership to certain officers of the
Company. The sales price was based on the appraised fair value of the building
less existing debt in the partnership and resulted in a gain to the Company of
approximately $1,271,000, of which approximately $338,000 was deferred. The
Bank's lease with the building partnership was substantially unchanged. The
deferred gain is being amortized over the remaining lease term and will be
immediately recognizable upon the related parties' sale of either the building
or their ownership in the Company.

Note 5. Subsequent Events

   The Company entered into a merger agreement on December 3, 2001, which will
result in the merger of the Company with and into Marshall & Ilsley Corporation
and the conversion of each outstanding share of common stock of the Company
into an equivalent number of shares of common stock of Marshall & Ilsley and/or
a cash payment with certain limitations of $7.40, subject to certain closing
conditions. The merger requires regulatory and shareholder approval and is
anticipated to close in the first quarter of 2002.

   On October 31, 2001, the Company sold all of its shares of Spectrum
Commercial Services Company to an investor group comprised of certain officers,
directors, and stockholders of the Company. The sales price approximated the
carrying value.

has remained unpaid for 90 days or more unless the loan is fully secured by
U.S. government securities,securities issued by agencies of the U.S.
government, marketable securities, verified cash surrender value of life
insurance, and/or assigned deposit accounts. Loans, or portions thereof which
are guaranteed by a government agency are also exempt.

   Loans which are on nonaccrual status are not restored to accruing status
until all delinquent principal and/or interest has been brought current.

ALLOCATION OF THE ALLOWANCE FOR LOAN LOSSES

  DISCUSSION OF RISK ELEMENTS IN THE LOAN PORTFOLIO AND FACTORS CONSIDERED IN
                   DETERMINING THE ALLOWANCE FOR LOAN LOSSES

   Bank management is responsible for recognizing, reporting, monitoring and
controlling delinquencies at proper levels and for prompt, diligent follow-up
of deteriorating credits. Regular procedures are established for routine
follow-up of deteriorating credits and for routine follow-up and collection of
delinquent loans. Immediate attention is given to personal or business loans
when any difficulty becomes apparent in regard to interest payments or
agreed-up principal reductions. Past dues are reviewed weekly. The status of
business loans is monitored by Bank management on a continuing basis through
interim financial statements, personal visits with the principals of the
companies involved, and through other sources such as credit reports. As
potential difficulties arise, management takes timely and appropriate action to
assist the borrower in correcting these problems, if possible, and to protect
the Bank from loss.

                                     D-11



   The Board is kept apprised of the status of all problem loans on a monthly
basis. Delinquency reports on problem loans and a list of loans past due over
30 days are reviewed at the regular monthly meeting.

   On a quarterly basis, bank management evaluates several external and
internal factors when determining the adequacy of the Allowance for Loan Losses
(ALL). The factors considered are local and national economic trends, loan
concentrations, growth in particular concentration areas, past due loans and
loans subject to classification in recent regulatory agency examinations or
independent audits.

   The ALL is maintained at a level adequate to provide for potential loan
losses through provisions charged to operating expense. This adequacy is based
upon a continuing review of loans which includes actual net loan loss
experienced, identification of problem situations which may affect the
borrower's ability to repay, an evaluation of current economic conditions, and
changes in the size and character of the loan portfolio.

   Loan losses are recognized through charges to the ALL.

   The Bank has implemented a risk rating process and the Senior Lender is
responsible for the overall accuracy of the risk ratings assigned to loans in
the portfolio.

   During the credit analysis process, the Bank will assign a risk rating based
upon eight risk rating classifications. When in doubt as to which rating to
assign, lenders are encouraged to use the lower risk rating. All risk ratings
are reviewed by the internal loan committee when the credit is presented for
approval and at the time of all subsequent reviews.

   Each month, an ALL adequacy analysis is completed and reviewed by senior
management and the Board of Directors. This report calculates a projected loan
loss allowance based on a factor assigned to each risk rated loan category,
standby letters of credit and undisbursed lines of credit. The risk rating

               Risk Rating Category                  Loss Factor
               --------------------                  -----------
                                                  
               Standby Letters Of Credit............     0.05%
               Undisbursed Lines Of Credit..........     0.25%
               Risk Rating Class 1..................     0.10%
               Risk Rating Class 2..................     0.50%

               Risk Rating Class 5 (Special Mention)     2.50%
               Risk Rating Class 6 (Substandard)....    15.00%
               Risk Rating Class 7 (Doubtful).......    50.00%
               Risk Rating Class 8 (Loss)...........   100.00%


   The Company's internal risk ratings of 6, 7 and 8 correspond with regulatory
definitions of substandard, doubtful and loss. The ALL is maintained at a level
that is greater than or equal to the adequacy calculation.

   CHARGE-OFFS ANTICIPATED IN 2002

   The management of Century Bank anticipates that loan charge-offs will be in
line with historical numbers of approximately .10% of total loans. For 2002
budget purposes, net charge-offs of $383,000 were planned. Bank management does
not foresee that the changing economic conditions will impact the original
budget.

                         INDEPENDENT AUDITOR'S REPORT

To the Board of Directors
Century Bancshares, Inc.
  and Subsidiary
Eden Prairie, Minnesota

   We have audited the accompanying consolidated balance sheets of Century
Bancshares, Inc. and Subsidiary as of December 31, 2000 and 1999, and the
related consolidated statements of income, stockholders' equity, and cash flows
for each of the years in the three-year period ended December 31, 2000. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

   In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Century
Bancshares, Inc. and Subsidiary as of December 31, 2000 and 1999, and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 2000, in conformity with accounting
principles generally accepted in the United States of America.

                    CENTURY BANCSHARES, INC. AND SUBSIDIARY

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies

   Nature of business: Century Bancshares, Inc., is a one-bank holding company
operating a single business segment. Its wholly owned subsidiary, Century Bank,
National Association (Bank), is a commercial bank with branch operations in
Eden Prairie, St. Louis Park, and Coon Rapids, Minnesota. The Bank provides
retail and commercial loan and deposit services principally to customers within
the Minneapolis-St. Paul metropolitan area.

   Basis of financial statement presentation and accounting estimates: The
consolidated financial statements have been prepared in conformity with
generally accepted accounting principles. In preparing the financial
statements, management is required to make estimates and assumptions that
affect the reported amounts of assets and liabilities as of the date of the
balance sheet and revenues and expenses for the period. Actual results could
differ from those estimates. A material estimate that is particularly
susceptible to significant change in the near term relates to the determination
of the allowance for loan losses.

   Principles of consolidation: The accompanying consolidated financial
statements include the accounts of Century Bancshares, Inc., and its wholly
owned subsidiary, Century Bank, National Association. These entities are
collectively referred to herein as the Company. All significant intercompany
balances and transactions have been eliminated in consolidation.

   Cash, cash equivalents, and cash flows: For purposes of reporting cash
flows, cash and cash equivalents includes cash on hand and amounts due from
banks. Cash flows from loans, federal funds sold, deposits, and short-term
borrowings are reported net.

   Available-for-sale securities: Securities classified as available-for-sale
are those debt securities that the Company intends to hold for an indefinite
period of time, but not necessarily to maturity. Any decision to sell a
security classified as available-for-sale would be based on various factors,
including significant movements in interest rates, changes in the maturity mix
of the Company's assets and liabilities, liquidity needs, regulatory capital
considerations, and other similar factors. Securities available for sale are
carried at fair value. Unrealized gains or losses, net of the related deferred
tax effect, are reported as increases or decreases in accumulated other
comprehensive income. Realized gains or losses, determined on the basis of the
cost of specific securities sold, are included in earnings.

   Loans held for sale: Loans that the Company has the intent to sell in the
foreseeable future are carried at the lower of aggregate cost or market value.
The market value calculation includes consideration of all open positions.
Gains and losses on sales of loans are recognized at trade dates and are
determined by the difference between the sales proceeds and the carrying value
of the loans. All sales are made without recourse.

   Loans and allowance for loan losses: Loans are stated at the amount of
unpaid principal, reduced by an allowance for loan losses.

                                     D-20



                    CENTURY BANCSHARES, INC. AND SUBSIDIARY

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies (Continued)

   The allowance for loan losses is established through a provision for loan
losses charged to expense. Loans are charged against the allowance for loan
losses when management believes that collectibility of the principal is
unlikely. The allowance is an amount that management believes will be adequate
to absorb estimated losses on existing loans that may become uncollectible,
based on evaluation of the collectibility of loans and prior loan loss
experience. This evaluation also takes into consideration such factors as
changes in the nature and volume of the loan portfolio, overall portfolio
quality, review of specific problem loans, and current economic conditions that
may affect the borrower's ability to pay. While management uses the best
information available to make its evaluation, future adjustments to the
allowance may be necessary if there are significant changes in economic
conditions.

   A loan is impaired when it is probable the Company will be unable to collect
all principal and interest payments due in accordance with the terms of the
loan agreement. Impaired loans are measured based on the present value of
expected future cash flows or, alternatively, the observable market price or
the fair value of the collateral if the loan is collateral dependent. The
amount of impairment, if any, and any subsequent changes are included in the
allowance for loan losses.

   Interest on loans is accrued daily on the outstanding balances. For impaired
loans, accrual of interest is discontinued on a loan when management believes,
after considering collection efforts and other factors, that the borrower's
financial condition is such that collection of interest is doubtful. Interest
on these loans is recognized only when actually paid by the borrower if
collection of the principal is likely to occur.

   Premises and equipment: Premises and equipment are stated at cost less
accumulated depreciation. Depreciation is provided principally by the
straight-line method over the estimated useful lives of the assets.

   Investment in limited partnership: The Company accounts for its investment
in a limited partnership using the equity method of accounting, under which the
Company's equity in the net income of the limited partnership is recognized as
other income in the Company's consolidated statement of income and added to the
investment account, and distributions received from the limited partnership are
treated as a reduction of the investment account (see also Note 18).

   Income taxes: Deferred taxes are provided on an asset and liability method
whereby deferred tax assets are recognized for deductible temporary differences
and operating loss or tax credit carry forwards, and deferred tax liabilities
are recognized for taxable temporary differences. Temporary differences are the
differences between the amounts of assets and liabilities recorded for income
tax and financial reporting purposes. Deferred tax assets are reduced by a
valuation allowance when management determines that it is more likely than not
that some portion or all of the deferred tax assets will not be realized.
Deferred tax assets and liabilities are adjusted for the effects of changes in
tax laws and rates on the date of enactment.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Summary of Significant Accounting Policies (Continued)

Employee benefit plan:

   Salary reduction-401(k) plan: The Company provides a 401(k) plan which
covers substantially all of the Company's employees who are eligible as to age
and length of service. A participant may elect to make contributions of up to
15 percent of the participant's annual compensation. The Company makes
contributions at the discretion of the Board of Directors and complies with the
requirements of the plan agreement.

   Fair value of financial instruments: The following methods and assumptions
were used by the Company in estimating the fair value of its financial
instruments:

   The carrying amounts reported in the consolidated balance sheets for cash
and cash equivalents, federal funds sold, available-for-sale securities, demand
deposits, NOW and money market deposits, savings deposits, short-term
borrowings, accrued interest receivable, and accrued interest payable
approximate their fair values.

   Fair values of variable-rate loans that reprice frequently and that have
experienced no significant change in credit risk are based on carrying values.
Fair values of all other loans are estimated based on discounted cash flows
using interest rates currently being offered for loans with similar terms to
borrowers with similar credit quality.

   Fair values of loans held for sale are based on quoted market prices of
similar loans sold on the secondary market.

   Fair values of fixed-rate time certificates are estimated using a discounted
cash flow calculation that applies interest rates currently being offered to a
schedule of aggregate expected monthly maturities.

   Fair values of fixed-rate notes payable are estimated using a discounted
cash flow calculation that applies an interest rate for similar debt offerings
to the expected maturity of the notes payable.

Note 2. Restrictions on Cash and Cash Equivalents

   The Bank is required to maintain reserve balances, in cash or on deposit
with the Federal Reserve Bank, based upon a percentage of deposits. The total
required reserve balances as of December 31, 2000 and 1999, were approximately
$3,185,000 and $1,712,000, respectively.

Note 3.  Available-for-Sale Securities (Continued)

   Anticipated maturities on mortgage-backed securities are not readily
determinable since they may be prepaid without penalty, and equity securities
(Federal Home Loan Bank and Federal Reserve Bank stock) do not have stated
maturity dates.

   Realized gains and losses:   There were no realized gains or losses for the
years ended December 31, 2000, 1999, and 1998.

   Pledged securities:   Available-for-sale securities with an approximate
carrying value of $11,005,000 and $14,499,000 at December 31, 2000 and 1999,
respectively, were pledged to secure public deposits and for other purposes as
required or permitted by law.

Changes in the unrealized gain (loss) on available-for-sale securities:

   In connection with the notes payable to bank, the Company has agreed, among
other things, to maintain certain financial ratios. The agreement also has
restrictions on the payment of dividends and limits future borrowing by the
Company.

Note 10. Stock Options

   The Company has granted nonqualified stock options to Board members and
certain employees of the Bank. These options allow for the purchase of common
stock at the exercise price set forth in the stock option agreement. The
options were accounted for under the provisions of APB Opinion No. 25 and
related interpretations. Options granted in 2000, 1999, and 1998 had an
exercise price approximating fair value at the date of grant; therefore, no
compensation cost has been recognized for these grants. Compensation cost based
on the grant date fair value of awards (the method described in FASB Statement
No. 123) was not material in 2000, 1999, and 1998.

   The outstanding options have a weighted-average exercise price of $1.67 and
a weighted-average contractual remaining life of 8.5 years. At December 31,
2000, 1,017,850 options with a weighted-average exercise price of $1.19 were
exercisable.

   The Company was able to recognize tax benefits in 2000 and 1999 as a result
of the exercise of stock options by the option holders. The benefit is equal to
the effective tax rate applied to the difference between the fair value of the
common stock issued and the exercise price.

Note 12.  Commitments, Contingencies, and Credit Risk

   Contingencies:  In the normal course of business, the Company is involved in
various legal proceedings. In the opinion of management, any liability
resulting from such proceedings would not have a material adverse effect on the
consolidated financial statements.

   Financial instruments with off-balance-sheet risk: The Company is party to
financial instruments with off-balance-sheet risk in the normal course of
business to meet the financing needs of its customers. These financial
instruments include commitments to extend credit and standby letters of credit.
They involve, to varying degrees, elements of credit risk in excess of amounts
recognized on the consolidated balance sheets.

   The Company's exposure to credit loss in the event of nonperformance by the
other parties to the financial instruments for these commitments is represented
by the contractual amounts of the instruments. The Company uses the same credit
policies in making commitments as it does for on-balance-sheet instruments.
These commitments were as follows:



                                                December 31

              Undisbursed lines of credit $73,485,000 $74,091,000
              Standby letters of credit..   9,486,000   7,429,000
                                          ----------- -----------
                                          $82,971,000 $81,520,000
                                          =========== ===========


   Undisbursed lines of credit:  Lines of credit are agreements to lend to a
customer as long as there is no violation of any condition established in the
contract. Since many of the lines of credit will not be fully drawn upon and
some may expire without being drawn upon, the total commitment amounts do not
necessarily represent future cash requirements. The Bank evaluates each
customer's creditworthiness on a case-by-case basis. If deemed necessary upon
extension of credit, the amount of collateral obtained is based on management's
credit evaluation of the party. Collateral held varies, but may include
accounts receivable, inventory, property and equipment, and income-producing
commercial properties.

   Standby letters of credit:  Standby letters of credit are conditional
commitments issued by the Bank to guarantee the performance of a customer to a
third party. Those guarantees are primarily issued to support public and
private borrowing arrangements. The credit risk involved in issuing letters of
credit is essentially the same as that involved in extending loan facilities to
customers. Collateral held varies as specified above and is required in
instances which the Bank deems necessary.

                                                ==========


   Total rent expense under these leases for the years ended December 31, 2000,
1999, and 1998, was approximately $710,000, $663,000, and $567,000,
respectively.

Financial instruments with concentrations of credit risk:

   Concentration over insured limits:  The nature of the Bank's business
requires that it maintain amounts due from banks which, at times, may exceed
federally insured limits. The Bank has not experienced any losses in such
accounts.

   Concentration by geographic location:  The Bank makes commercial,
residential, and consumer loans to its customers primarily in the Bank's
primary trade areas of Eden Prairie, St. Louis Park, and Coon Rapids and also
in the Bank's secondary trade area, which encompasses the entire
Minneapolis-St. Paul metropolitan area. Although the Bank's loan portfolio is
diversified, a substantial portion of the Bank's customers' ability to honor
their contracts is dependent upon the local business economy, which is taken
into consideration by management in determining the allowance for loan losses.

   Concentration by industry:  Included in the Company's loan portfolio are
concentrations of loans secured by loans related to real estate. A summary of
those concentrations at December 31, 2000, is as follows:


                                                  
               Loans secured by real estate:

Note 13.  Benefit Plan

   Salary reduction--401(k) plan:  Company contributions to the plan were
$148,000, $55,000, and $50,000 in 2000, 1999, and 1998, respectively.

Note 14. Loans and Other Transactions With Related Parties

   Shareholders of the Company, executive officers, and directors, including
their families and companies of which they are principal owners, are considered
to be related parties. These related parties were loan customers of and had
other transactions with the Bank in the ordinary course of business. In
management's opinion, these loans and transactions were on the same terms as
those for comparable loans and transactions with nonrelated parties.

   Loans:  Total loans to related parties were approximately $10,022,000 and
$5,841,000 at December 31, 2000 and 1999, respectively.

   Leases:  The Company leases its main office from a limited partnership in
which the Company, as a limited partner, has a 60 percent ownership interest.
The limited partnership and the Company share common ownership. The Company has
a first-floor lease and a second-floor lease. Both leases have 11-year terms
expiring in April 2011. In addition to the base rents, the Company pays
operating costs (taxes, insurance, maintenance, and repairs). The monthly
amounts for operating costs are adjusted annually based on the actual operating
costs incurred. These leases are accounted for as operating leases (see also
Note 18).

Note 15. Regulatory Capital Requirements

   The Bank is subject to various regulatory capital requirements administered
by the Bank's primary federal regulatory agency. Failure to meet minimum
capital requirements can initiate certain mandatory and possibly additional
discretionary actions by regulators that, if undertaken, could have a direct
material effect on the Company's consolidated financial statements. Under
capital adequacy guidelines and the regulatory framework for prompt corrective
action, the Bank must meet specific capital guidelines that involve
quantitative measures of assets and certain off-balance-sheet items as
calculated under regulatory accounting practices. The Bank's capital amounts
and classification are also subject to qualitative judgments by the regulators
about components, risk weightings, and other factors.

   Quantitative measures established by regulation to ensure capital adequacy
require the Bank to maintain minimum ratios (set forth in the table below) of
total and Tier I capital to risk-weighted assets, and of Tier I capital to
average assets (all as defined in the regulations). Management believes, as of
December 31, 2000, that the Bank meets all capital adequacy requirements to
which it is subject.

Note 15.  Regulatory Capital Requirements (Continued)

   As of December 31, 2000, the most recent notification from the Bank's
primary regulator (OCC) categorized the Bank as well capitalized under the
regulatory framework for prompt corrective action. To be categorized as well
capitalized, the Bank must maintain minimum total risk-based, Tier I
risk-based, and Tier I leverage ratios as set forth in the table below. There
are no conditions or events since that notification that management believes

   Fair value of commitments:  The estimated fair value of fee income on
letters of credit at December 31, 2000 and 1999, is insignificant. Loan
commitments on which the committed interest rate is less than the current
market rate are also insignificant at December 31, 2000 and 1999.

   Interest rate risk:  The Bank assumes interest rate risk (the risk that
general interest rate levels will change) as a result of its normal operations.
As a result, the fair values of the Bank's financial instruments will change
when interest rate levels change, and that change may be either favorable or
unfavorable to the Bank. Management attempts to match maturities of assets and
liabilities to the extent believed necessary to minimize interest rate risk.
However, borrowers with fixed-rate obligations are more likely to prepay in a
falling-rate environment and less likely to prepay in a rising-rate
environment. Conversely, depositors who are receiving fixed rates are more
likely to withdraw funds before maturity in a rising-rate environment and less
likely to do so in a falling-rate environment. Management monitors rates and
maturities of assets and liabilities and attempts to minimize interest rate
risk by adjusting terms of new loans and deposits and by investing in
securities with terms that mitigate the Bank's overall interest rate risk.

Note 18. Subsequent Events

   Merger:  The Company entered into a merger agreement on December 3, 2001,
which will result in the merger of the Company with and into Marshall & Ilsley
Corporation and the conversion of each outstanding share of common stock of the
Company into an equivalent number of shares of common stock of Marshall &
Ilsley and/or a cash payment with certain limitations of $7.40, subject to
certain closing conditions. The merger requires regulatory and shareholder
approval and is anticipated to close in the first quarter of 2002.

Note 18. Subsequent Events (Continued)

   Spectrum Commercial Services Company:  In March 2001, the Company acquired
certain loans approximating $15 million of an asset-based lending and factoring
company through a newly formed subsidiary, Spectrum Commercial Services Company
(Spectrum). The loans were acquired by the assumption of approximately $11.5
million of debt and payment of $3.5 million of cash. Effective October 31,
2001, the Company sold all of its shares of Spectrum to an investor group
comprised of certain officers, directors, and stockholders of the Company. The
sales price approximated the carrying value.

   Century Bank Building Partnership:  In September 2001, the Company sold its
60 percent limited partnership interest in Century Bank Building Partnership to
certain officers of the Company. The sales price was based on the appraised
fair value of the building less existing debt in the partnership and resulted
in a gain to the Company of approximately $1,271,000, of which approximately
$338,000 was deferred. The Bank's lease with the building partnership was
substantially unchanged. The deferred gain is being amortized over the
remaining lease term and will be immediately recognizable upon the related
parties' sale of either the building or their ownership in the Company.

                  INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20. Indemnification of Directors and Officers.

   Sections 180.0850 to 180.0859 of the Wisconsin Business Corporation Law
require a corporation to indemnify a director or officer who is a party to any
threatened, pending or completed civil, criminal, administrative or
investigative action, suit, arbitration or other proceeding, whether formal or
informal, which involves foreign, federal, state or local law and which is
brought by or in the right of the corporation or by any other person. A
corporation's obligation to indemnify any such person includes the obligation
to pay any judgment, settlement, penalty, assessment, forfeiture or fine,
including any excise tax assessed with respect to an employee benefit plan, and
all reasonable expenses including fees, costs, charges, disbursements,
attorneys' and other expenses, except in those cases in which liability was
incurred as a result of the breach or failure to perform a duty which the
director or officer owes to the corporation and the breach or failure to
perform constitutes: (i) a willful failure to deal fairly with the corporation
or its shareholders in connection with a matter in which the director or
officer has a material conflict of interest; (ii) a violation of criminal law,
unless the person has reasonable cause to believe his conduct was lawful or had
no reasonable cause to believe his conduct was unlawful; (iii) a transaction
from which the person derived an improper personal profit; or (iv) willful
misconduct.

   Unless otherwise provided in a corporation's articles of incorporation or
bylaws, or by written agreement, an officer or director seeking indemnification
is entitled to indemnification if approved in any of the following manners: (i)
by majority vote of a disinterested quorum of the board of directors, or if
such quorum of disinterested directors cannot be obtained, by a majority vote
of a committee of two or more disinterested directors; (ii) by independent
legal counsel; (iii) by a panel of three arbitrators; (iv) by affirmative vote
of shareholders; (v) by a court; or (vi) with respect to any additional right
to indemnification granted, by any other method permitted in Section 180.0858
of the Wisconsin Business Corporation Law.

   Reasonable expenses incurred by a director or officer who is a party to a
proceeding may be reimbursed by a corporation at such time as the director or
officer furnishes to the corporation a written affirmation of his good faith
belief that he has not breached or failed to perform his duties and a written
undertaking to repay any amounts advanced if it is determined that
indemnification by the corporation is not required.

   The indemnification provisions of Section 180.0850 to 180.0859 are not
exclusive. A corporation may expand an officer's or director's rights to
indemnification: (i) in its articles of incorporation or bylaws; (ii) by
written agreement; (iii) by resolution of its board of directors; or (iv) by
resolution of a majority of all of the corporation's voting shares then issued
and outstanding.

   As permitted by Section 180.0858, Marshall & Ilsley has adopted
indemnification provisions in its bylaws which closely track the statutory
indemnification provisions with certain exceptions. In particular, Section 7.1
of Marshall & Ilsley's bylaws, among other items, provides that (i) an
individual shall be indemnified unless it is proven by a final judicial
adjudication that indemnification is prohibited and (ii) payment or
reimbursement of expenses, subject to certain limitations, will be mandatory
rather than permissive. Marshall & Ilsley has purchased directors' and
officers' liability insurance which insures Marshall & Ilsley's officers and
directors against certain liabilities which may arise under the Securities Act
of 1933.

Item 22. Undertakings.

   (a) The undersigned registrant hereby undertakes:

      (1) To file, during any period in which offers or sales are being made, a
   post-effective amendment to this registration statement:

          i. To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933.

          ii. To reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth
       in the registration statement. Notwithstanding the foregoing, any
       increase or decrease in volume of securities offered (if the total
       dollar value of securities offered would not exceed that which was
       registered) and any deviation from the low or high end of the estimated
       maximum offering range may be reflected in the form of prospectus filed
       with the SEC pursuant to Rule 424(b) if in the aggregate, the changes in
       volume and price represent no more than 20% change in the maximum
       offering price set forth in the "Calculation of Registration Fee" table
       in the effective registration statement.

          iii. To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement.

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

      (3) To remove from registration by means of a post-effective amendment
   any of the securities being registered which remain unsold at the
   termination of the offering.

   (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of any
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 therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

   (c) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed to be underwriters, in addition to the information
called for by the other items of the applicable form.

   (d) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

   (e) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the

                                     II-2



registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the 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.

   (f) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through
the date of responding to the request.

   (g) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

                                     II-3



                                  SIGNATURES

   Pursuant to the requirements of the Securities Act of 1933, the registrant
has duly caused this Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the City of Milwaukee, State of
Wisconsin, on January 14, 2002.
