                      GREATER COLUMBIA BANCSHARES, INC.
                          222 EAST WISCONSIN STREET
                           PORTAGE, WISCONSIN 53901

                              February ___, 1996
Dear Fellow Shareholder:

         Following this letter is a notice of a Special Meeting of the
Shareholders of Greater Columbia Bancshares, Inc.  (the "Company"), a Proxy
Statement/Prospectus and a proxy card for the Special Meeting.  The Special
Meeting will commence at _____ __.m. on _______________, 1996 at the principal
executive offices of the Company at 222 East Wisconsin Street, Portage,
Wisconsin.

          The Company shareholders will be asked to vote on a proposal to
approve an Agreement and Plan of Merger among Associated Banc-Corp
("Associated"), Associated Banc-Shares, Inc. ("Holding"), a wholly-owned
subsidiary of Associated, and the Company dated as of December 22, 1995 (the
"Merger Agreement").  Associated is a Wisconsin bank holding company owning all
of the capital stock of eight commercial banks located in Wisconsin and
Illinois.

         Subject to receipt of regulatory approval, approval by holders of a
majority of the shares of the Company Common Stock and satisfaction of other
conditions, the Merger Agreement provides that the Company will combine its
business and operations with those of Holding through a statutory merger (the
"Merger"), and will thereafter operate its banking business as "Associated Bank
Portage."  As described in the accompanying Proxy Statement/Prospectus, each of
the directors of the Company has agreed to vote their shares in favor of
approval of the Merger Agreement.  Assuming compliance with such agreement, and
provided the Merger Agreement has not been terminated prior to its being voted
upon by the Company shareholders, the approval of the Merger Agreement is
assured.

         If the Merger becomes effective, each share of the Company Common
Stock will be converted into 1.0665 shares of Associated Common Stock.   See
"The Merger - Merger Consideration" in the accompanying Proxy
Statement/Prospectus.  Associated Common Stock trades on The Nasdaq Stock
Market and the shares of Associated Common Stock to be issued to you in the
Merger will offer greater liquidity than that of the Company Common Stock which
you presently own.

         The Merger is intended to be tax-free for federal income tax purposes
to Company shareholders who receive Associated Common Stock in exchange for
Company Common Stock, except as discussed in "The Merger-Certain Material
Federal Income Tax Consequences" in the accompanying Proxy
Statement/Prospectus.  No fractional shares of Associated Common Stock will be
issued in the Merger.  Company shareholders entitled to a fractional share of
Associated Common Stock will receive an amount of cash calculated upon the
average closing prices as reported on The Nasdaq Stock Market for a specified
period.  Company shareholders are advised to consult their tax advisors with
respect to income tax consequences of the transaction.  Details of the Merger
are set forth in the accompanying Proxy Statement/Prospectus.  We encourage you
to read it carefully.

         The Board of Directors of the Company has unanimously approved the
Merger Agreement as being in the best interest of the Company and its
shareholders.  Your Board recommends that the Company shareholders vote to
approve the Merger Agreement.

         Whether or not you plan to attend the Special Meeting, holders of the
Company Common Stock are asked to please complete, date and sign the enclosed
proxy card, which is solicited by the Board of Directors of the Company, and
return it promptly in the accompanying envelope, which requires no postage if
mailed in the United States.  If you later find that you may be present at the
Special Meeting or for any other reason desire to revoke your proxy, you may do
so at any time before it is voted.

         IN ORDER TO APPROVE THE MERGER AGREEMENT, IT IS NECESSARY THAT HOLDERS
OF AT LEAST A MAJORITY OF THE OUTSTANDING SHARES OF THE COMPANY VOTE IN FAVOR
OF THE MERGER AGREEMENT.
                                Very truly yours,


                                /s/ Beryl G. Pascavis

                 into Holding (the "Merger") (a copy of the Merger Agreement is
                 attached as Exhibit A hereto).

         2.      To transact such other business as may properly come before

VOTING AGREEMENT:                 of the Company Common Stock entitled to vote at the Special Meeting is
                                  required to approve the Merger Agreement under the Wisconsin Business
                                  Corporation Law (the "WBCL").

                                  Associated has entered into a Voting Agreement dated as of December 22, 1995
                                  (the "Voting Agreement") attached hereto as Exhibit B with each of the
                                  directors of the Company pursuant to which the directors have agreed to vote
                                  their shares (i) in favor of the adoption and approval of the Merger
                                  Agreement and the Merger and (ii) against any Competing Transaction (as such
                                  term is defined herein) which generally includes an acquisition of control
                                  of, or a significant equity interest in or significant assets of, the
                                  Company by a third party in the form of a merger, consolidation, share
                                  exchange, business combination or other similar transaction, acquisition of
                                  assets or shares or otherwise, or certain announcements, proposals or offers
                                  with respect thereto.  The directors of the Company hold 596,935 shares, or
                                  approximately 65.8% of the Company Common Stock entitled to vote at the
                                  meeting.  Assuming compliance with the terms of the Voting Agreement and
                                  provided the Merger Agreement has not been terminated prior to its being
                                  voted upon by the Company shareholders, the approval and adoption of the
                                  Merger Agreement are assured.  The Voting Agreement also provides that
                                  Associated has the exclusive right to purchase any or all of the shares of
                                  Company Common Stock owned by the directors of the Company for $37.3275 per
                                  share, payable in cash, subject to any necessary regulatory approval, after
                                  a material breach of the Merger Agreement by the Company, a breach by a
                                  Party Shareholder, or the acquisition or overtly threatened acquisition of
                                  5% of the stock or a material portion of the assets of the Company or the
                                  Bank.  The purchase right is not exercisable as of the date hereof.  The
                                  purchase price per share under the Voting Agreement equalled the value of
                                  the Company Common Stock based upon the trading price of Associated Common
                                  Stock at the date that the Voting Agreement was requested by Associated.
                                  The execution and delivery of the Voting Agreement was a condition to
                                  Associated entering into the Merger Agreement.  The Voting Agreement may
                                  have the effect of discouraging persons who might now or in the future be
                                  interested in acquiring all of or a significant interest in the Company from
                                  considering or proposing such an acquisition, even if such persons were
                                  prepared to pay a higher price per share for the Company Common Stock than
                                  the price per share implicit in the Exchange Ratio.  The Voting Agreement is
                                  intended to increase the likelihood that the Merger will be consummated.
                                  See "The Merger - The Voting Agreement."

REASONS FOR THE MERGER:           The Board of Directors of the Company believes that the Merger will have a
                                  positive impact on the customers and employees of the Company by providing
                                  overall additional financial strength to the banking business of the Bank.
                                  Shareholders of the Company will benefit as a result of the enhanced
                                  liquidity, marketability and dividend paying capacity of the Associated
                                  Common Stock to be received in the Merger.  The Board of Directors of
                                  Associated believes the Merger will enable Associated to increase its
                                  presence and heighten its visibility in South Central Wisconsin.  See "The
                                  Merger - Reasons for the Merger."

RECOMMENDATION OF THE             The Board of Directors of the Company, after consideration of the terms and
COMPANY'S BOARD OF                conditions of the Merger Agreement and other factors deemed relevant by the
DIRECTORS:                        Board of Directors, believes that the Merger and the Exchange Ratio are fair
                                  to

                                  and in the best interests of the shareholders of the Company.  The Board
                                  of Directors of the Company has approved the Merger Agreement and the
                                  transactions contemplated thereby.  See "The Merger-Background of the
                                  Merger," "- Reasons for the Merger" and "- Recommendations of the Board of
                                  Directors of the Company."

                                  shares of Associated Common Stock which would otherwise have been issued
                                  pursuant to the Merger, receipt by Associated of a written environmental
                                  evaluation by Associated's environmental consultant of the Company's real
                                  property stating that the Company's property complies with environmental
                                  laws and that there are no material contingent liabilities, that the Company
                                  shall have taken reasonably appropriate action in response to any
                                  environmental condition identified by Associated's environmental consultant,
                                  and that the Company's consolidated after-tax earnings for calendar year
                                  1995 (with certain adjustments) were in excess of $2,500,000.  See "Certain

TERMINATION:                      The Merger Agreement may be terminated by the applicable Board of Directors
                                  at any time prior to the Effective Time (whether before or after approval of
                                  the Merger by the shareholders of the Company):  (i) by mutual consent of
                                  Associated and the Company; (ii) by Associated or the Company if there has
                                  been a breach by the other party in any material respect of any
                                  representation, warranty, covenant or agreement in the Merger Agreement, or
                                  if any representation or warranty of the Company or Associated shall be
                                  discovered to have become untrue in any material respect, in either case
                                  which breach has not been cured within 10 business days following receipt by
                                  the non-terminating party of notice of such breach; (iii) by Associated or
                                  the Company if any permanent injunction preventing the consummation of the
                                  Merger shall have become final and nonappealable; (iv) by Associated or the
                                  Company if the Merger shall not have been consummated before July 30, 1996
                                  for a reason other than the failure of the terminating party to comply with
                                  its obligations under the Merger Agreement; (v) by Associated or the Company
                                  if the Board of Governors of the Federal Reserve System (the "Federal
                                  Reserve Board") or the Wisconsin Commissioner of Banking (the "Wisconsin
                                  Commissioner") have denied approval of the Merger, and neither Associated
                                  nor the Company has, within 30 days after the entry of such order, filed a
                                  petition seeking review of such order as provided by applicable law; (vi) by

                                  fails to take reasonably appropriate action in
                                  response to any environmental condition identified by Associated's
                                  environmental consultant; or (vii) by Associated if dissenters' rights are
                                  exercised with respect to in excess of 10% of the Company Common Stock.  See
                                  "Certain Provisions of the Merger Agreement - Termination."

REGULATORY APPROVALS              The Merger is subject to prior approval by the Federal Reserve Board and the
REQUIRED:                         Wisconsin Commissioner.  See "The Merger - Regulatory Approvals Required."

CERTAIN MATERIAL                  The Merger is conditioned upon Associated and the Company receiving an
FEDERAL INCOME                    opinion of independent counsel to Associated, subject to customary
TAX CONSEQUENCES:                 assumptions and representations, to the effect that the Merger will be a
                                  tax-free reorganization for federal income tax purposes.  Such opinion,
                                  however, is not binding on the Internal Revenue Service.  In the event that
                                  the Merger qualifies as a tax-free reorganization, no gain or loss will be
                                  recognized by holders of the Company Common Stock upon conversion of their
                                  shares of stock into shares of Associated Common Stock, except to the extent
                                  they receive cash in lieu of fractional share interests of Associated Common
                                  Stock, and no gain or loss will be recognized by Associated, Holding or the
                                  Company.  See "The Merger - Certain Material Federal Income Tax
                                  Consequences."

ANTICIPATED ACCOUNTING            The Merger is expected to qualify as a "pooling of interests" for accounting
TREATMENT:                        and financial reporting purposes.  The receipt of an opinion from KPMG Peat
                                  Marwick LLP, the independent public accountants of Associated, confirming
                                  that the Merger will qualify for "pooling of interests" accounting treatment
                                  is a condition to consummation of the Merger.  See "The Merger - Anticipated
                                  Accounting Treatment."

DISSENTING SHAREHOLDERS'          Holders of Company Common Stock who comply with the procedural requirements
RIGHTS:                           of the WBCL will have appraisal rights in connection with the Merger.
                                  Pursuant to Section 180.1302(1) of the WBCL, holders of shares of stock
                                  entitled to notice of a shareholders' meeting at which shareholders are to
                                  vote on a merger are provided, subject to certain procedural requirements,
                                  with statutory rights of appraisal pursuant to which such shareholders may
                                  be entitled to receive cash in the amount of the "fair value" of their
                                  shares (as determined pursuant to the WBCL) instead of the shares or cash
                                  offered pursuant to the merger.  See "The Merger - Dissenters' Rights" and
                                  Exhibit C hereto.

CERTAIN CONSIDERATIONS:           In deciding whether to vote in favor of the Merger Agreement, shareholders
                                  of the Company should carefully evaluate the matters set forth in the
                                  section herein entitled "The Merger - Certain Considerations."  Shareholders
                                  of the Company should consider that the exercise of dissenters' rights is
                                  the only alternative to avoid conversion of Company Common Stock to shares
                                  of Associated Common Stock as shareholder approval is assured pursuant to
                                  the terms of the Voting Agreement, and the changing legislative and
                                  regulatory environment affecting the banking and financial services
                                  businesses in which Associated and the Company engage.


INTERESTS OF CERTAIN              Associated (through the Bank as employer) will enter into a two year
PERSONS IN THE MERGER:            employment agreement with Mr. Pascavis.  See "The Merger - Interests of
                                  Certain Persons in the Merger."

THE COMPANY COMMON STOCK

         The Company Common Stock is not listed on any exchange nor is there an
established trading market for Company Common Stock.  Although it is quoted and
occasionally trades in the over-the-counter market, only sporadic "bid" or
"ask" prices are available.  Since January 1993, the bid price has ranged from
$20 to $36.50 per share as reported by the National Quotation Bureau.  Such
prices do not reflect retail mark-up, mark-down or commission.  Management of
the Company does not have knowledge of the prices paid in all transactions
involving its shares.  Because of the lack of an established public market for
shares of Company Common Stock, the range of prices indicated may not reflect
the prices which would be paid for such shares in an active market. On January
29, 1996, the quoted market price per share of Company Common Stock was $36.50
bid.

         In November 1993, the Company completed a rights offering of 260,000
shares of Company Common Stock at a subscription price of $23.00 per share to
shareholders of the Company who were Wisconsin residents.  Company shareholders
received nontransferable subscription rights to purchase Company Common Stock
at the rate of one share of Company Common Stock for each 2.4 shares of Company
Common Stock held of record.

         The Board of Directors of the Company declared dividends in each of
1993, 1994 and 1995 of $0.60 per share, $1.26 per share and $1.26 per share,
respectively.  Pursuant to the Merger Agreement, the ability of the Company to
pay dividends on the Company Common Stock prior to the Effective Time has been
restricted except that commencing February 15, 1996, the Company is permitted
to declare and pay a quarterly dividend not to exceed $0.32 per share.  See
"The Merger - Pre-Merger Dividend Policy."

  On the Record Date, there were 151 holders of record of the Company Common
Stock.

                                 RECENT RESULTS

         For the year ended December 31, 1995, Associated reported net income
of $46.7 million up 12.0% compared to 1994.  Net income for the fourth quarter
1995 was $12.5 million up 14.6% from the comparable prior period in 1994.
Earnings per share were $2.83 and $0.76 for the year ended December 31, 1995
and for the fourth quarter 1995, respectively.  Total assets were $3.7 billion
at December 31, 1995 up 8.2% from reported assets at December 31, 1994.  On
January 24, 1996, Associated declared a dividend of $0.27 per share payable
February 15, 1996 to shareholders of record as of February 5, 1996.

         For the year ended December 31, 1995, the Company reported net income
of $1.4 million down 38.5% compared to 1994.  Earnings per share were $1.52.
Net income decreased primarily because the Company recorded a provision for
loan loss of $1.1 million ($660,000 after tax), pursuant to the terms of the
Merger Agreement.  Total assets were $210 million down 0.5% from reported
assets at December 31, 1994.

                             PROPOSED ACQUISITIONS

         On November 10, 1995 and January 23, 1996, Associated signed
definitive merger agreements for proposed stock-for-stock merger transactions
with SBL Capital Bank Shares, Inc. ("SBL") and F&M Bankshares of Reedsburg,
Inc. ("F&M"), respectively.  SBL is a $63.4 million one bank holding company
with main offices in Lodi, Wisconsin.  F&M is a $140 million one bank holding
company with main offices in Reedsburg, Wisconsin.  SBL is expected to be
consummated during the first quarter of 1996 and F&M during the second quarter
of 1996.  Each of these acquisitions is expected to be accounted for as a
pooling of interests.  There is no assurance that such transactions will be
consummated or that if consummated, that the proposed terms will not be
modified.  Moreover, Associated from time to time is engaged in preliminary
negotiations for potential acquisitions involving stock-for-stock mergers or
cash purchases.  Such proposed acquisitions are announced when agreements in
principle have been reached.

VOTING OF PROXIES

         Shares represented by all properly executed proxies for the Company
Common Stock received in time for the Special Meeting will be voted at the
Special Meeting in the manner specified by the holders thereof.  Proxies which
do not contain voting instructions will be voted FOR approval of the Merger

         It is not expected that any matter other than that referred to herein
will be brought before the Special Meeting.  If, however, other matters are
properly presented, the persons named as proxies will vote in accordance with
their judgment with respect to such matters.

REVOCABILITY OF PROXIES

         The grant of a proxy on the enclosed form of proxy does not preclude a
shareholder from voting in person.  A shareholder may revoke a proxy at any
time prior to its exercise by delivering to the Secretary of the Company a duly
executed proxy or revocation of proxy bearing a later date or by voting in
person at the Special Meeting.  Attendance at the Special Meeting will not of
itself constitute revocation of a proxy.

outstanding.  Shares representing a majority of the outstanding shares of the
Company Common Stock entitled to vote must be represented in person or by proxy
at the Company Meeting in order for a quorum to be present.  Abstentions will
be treated as shares that are present and entitled to vote for purposes of
determining the presence of a quorum but as unvoted for purposes of determining
the approval of the Merger Agreement.  If a broker or other holder of record
indicates on the proxy that it does not have discretionary authority as to
certain shares to vote on a particular matter, those shares will not be
considered as present and entitled to vote with respect to that matter.

SOLICITATION OF PROXIES

         The Company will bear the cost of the solicitation of proxies from its
shareholders, except that Associated and the Company will share equally the
cost of printing this Proxy Statement/Prospectus and all regulatory filing fees
in connection therewith.  In addition to solicitation by mail, the directors,
officers and employees of the Company may solicit proxies from shareholders of
the Company by telephone or telegram, or in person, but will receive no
additional compensation for such services.

         SHAREHOLDERS SHOULD NOT RETURN THEIR STOCK CERTIFICATES WITH THEIR
PROXY CARDS.  AS SOON AS PRACTICABLE FOLLOWING THE EFFECTIVE TIME, THE COMPANY
SHAREHOLDERS WILL BE PROVIDED WITH MATERIALS RELATING TO THE EXCHANGE OF THEIR
STOCK CERTIFICATES.  SEE "THE MERGER  - CONVERSION OF SHARES; PROCEDURES FOR
EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES."

                                   THE MERGER

         This section of the Proxy Statement/Prospectus describes certain
aspects of the proposed Merger.  To the extent that it relates to the Merger
Agreement, the following description does not purport to be complete and is
qualified in its entirety by reference to the Merger Agreement which is
attached hereto as Exhibit A and is incorporated herein by reference.  All
shareholders are urged to read the Merger Agreement and the other exhibits to
this Proxy Statement/Prospectus in their entirety.



                                      16

<PAGE>   23


BACKGROUND OF THE MERGER

         For the past several years, the Board of Directors of the Company has
monitored the future of independent banks in smaller communities in Wisconsin
such as Portage.  The Board continually considered the potential increase in
banking competition in the Portage area, the need for large capital
expenditures required to provide desired customer service and the increased
rules and regulations imposed by regulatory authorities upon the banking
industry.  The Board recognized the banking industry has substantially changed
in recent years with potential changes of equal or greater magnitude for the
industry foreseeable in the future.

         As a result, the Board determined in late 1994 to formally consider
questions involving the future of the Company and the Bank.  The Board
determined that affiliation with a large organization would aid the Company in
competitive compliance and managerial respects as well as provide shareholders
of the Company with greater liquidity and diversification of their investment.
The Board directed its counsel and independent accountants to prepare a
descriptive memorandum with respect to the Company and the Bank for
distribution to potential acquirors.  Such memorandum was completed in February
1995 and counsel for the Company then solicited expressions of interest from
over a dozen bank holding companies operating in the State of Wisconsin.  Those
solicitations produced three bona fide offers for acquisition of the Company
subject to due diligence review.

         The solicitations of interest sought answers to specific questions
with regard to both the economic and social aspects of any proposed transaction
between the potential acquiror and the Company to determine not only the
financial aspects of the proposal but also the operational similarities between
the Company and each potential acquiror.  Each of the three interested holding
companies also submitted specific listings of requested material for their
respective due diligence reviews.  Following the due diligence, specific bids
for the Company were presented by each of the three holding companies which
included Associated.  Counsel and the independent accountants of the Company
also discussed with each of the three bidders their specific bids.  Following
receipt of these specific bids, the Board, assisted by counsel and independent
accountants, conducted an evaluation of each of the bids.  One of the specific
bids included a cash proposal and an alternative part-cash, part-stock
proposal. Subsequent to this bidder's due diligence on the Company, such bid
was denominated in cash at $28.00 per share or in a part-cash, part-stock
structure at an implied value of an unspecified amount less than $28.00 per
share based upon the then current market price of the bidder's stock which was
publicly-traded. Neither the cash proposal nor the part-cash, part-stock
proposal (which was structured to be tax-free to shareholders who did not elect
cash consideration) were as attractive from an economic standpoint as the
tax-free proposals from the other two final bidders.  As a result, the Board
determined not to pursue further discussions with the cash bidder.  Additional
discussions were then conducted with each of the remaining two bidders.  The
Board considered the other stock-for-stock bid and ultimately rejected it after
considering the past performance of bidder's publicly-traded stock and the
Board's perception of the long-range potential stock appreciation relative to
Associated.  The Board also concluded that Associated would be a better merger
partner from the standpoint of various social issues and management philosophy.
These discussions resulted in the approval by the Board of the Associated
proposal and the execution of the Letter of Intent with Associated as of August
23, 1995.  The terms of the letter of intent were embodied in the Merger
Agreement and Voting Agreement which were executed on December 22, 1995.

         The Merger Agreement was entered into by the Company after full
consideration of the various factors having an effect upon a determination of
the fair value of the Company Common Stock in the context of a Merger.  In
determining the amount of consideration to be received by the shareholders of
the Company, the Board considered the relative financial condition and earnings
and the history of dividend payments by Associated and the Company, the
benefits of diversification in banking environments in the stock price, as well
as the prospective growth potential of Associated and the Company based on
their respective businesses, locations and market areas.

         The Directors of the Company concluded they would not engage an
investment banking firm to render an opinion that the Exchange Ratio is fair
from a financial point of view.  As noted above, the Board concluded it would
recommend the Merger and Exchange Ratio as fair to, and in the best interests
of, the shareholders of the Company when the price of Associated Common Stock
ranged between $32 and $34 per share.  Although the Board



                                      17

<PAGE>   24

was aware that the price would continue to fluctuate until the Effective Time,
the Directors believed the benefit to the Company and its shareholders from a
fairness opinion would not be commensurate with the cost of such opinion.  On
the date of the Company's execution of the Letter of Intent between Associated
and the Company on August 23, 1995, the aggregate consideration based on the
closing price of Associated Common Stock on that date as reported on The Nasdaq
Stock Market ($33.00 per share) was approximately $31.9 million or
approximately $35.19 per share of Company Common Stock.  On December 22, 1995,
the date of execution of the Merger Agreement, the value of the transaction was
approximately $37.7 million or $41.59 per share based on the closing price of
Associated Common Stock on that date as reported on The Nasdaq Stock Market of
$39.00 per share.

         The Board of Directors of the Company has approved the Merger
Agreement and believes the proposed Merger is in the best interest of the
Company and its shareholders.  Accordingly, the Board recommends that the
shareholders of the Company vote in favor of adoption of the Merger Agreement
as discussed herein. The Merger will afford the Bank the advantage of joining a
multi-bank holding company while preserving the individual identity of the
Bank.  Because of Associated's size and financial strength, it has a greater
range of financing alternatives available to raise any additional capital
necessary to meet the financial requirements of the Bank. The Merger will
permit the Bank to continue to function with a large degree of autonomy under
its own officers and its own Board of Directors and, in addition, will enable
the Bank through its affiliation with Associated to improve and expand its
services and to realize administrative economies through centralized operations
by more effectively utilizing its present personnel and by permitting the
deployment of additional skilled personnel on an economical basis, particularly
in the audit, trust, investment and data processing areas.  The affiliation
with other banks owned by Associated will permit group participation and credit
extensions which will enable the Bank to effectively handle the credit needs of
businesses which might otherwise do their banking outside the service area of
the Bank. The outstanding shares of Associated Common Stock are, and the shares
of such stock to be issued in the Merger for Company Common Stock, will be,
actively traded on The Nasdaq Stock Market and hence enjoy greater liquidity
than shares of Company Common Stock which are not regularly traded in any
established market.  The active trading of Associated Common Stock also
provides a means of accurately valuing the shares received in the Merger for
which valuation is not now available for shares of Company Common Stock.

REASONS FOR THE MERGER

         The Company.  In considering the Merger, the directors of the Company
reviewed the terms and conditions of the proposed Merger Agreement, along with
certain business and financial information relating to Associated and the
Company.  In addition to the factors discussed above, the Board of Directors of
the Company determined to approve the proposed transaction primarily because
the Merger will increase the financial strength of the Bank by enabling it to
better serve its depositors and customers, to provide additional opportunities
for professional advancement for the Bank's employees, and to be more
competitive with other bank subsidiaries of large bank holding companies
currently doing business in South Central Wisconsin or which might locate in
the community.  The directors of the Company also concluded that the Merger
will enhance both the long-term and short-term value of the Company
shareholders' investments.  Among the additional factors important to the
directors of the Company in determining to approve the Merger, were: (i) the
increased opportunity and resources to serve the Bank's customers; (ii) the
possibility for career enhancement which employees of the Company and the Bank
might be provided as a result of the Merger; (iii) the increased resources and
expertise to keep the Bank competitive and meet the ever changing demands of
the banking industry; (iv) the marketability and liquidity of Associated Common
Stock and the consistent dividend history and rate of dividends of the
Associated Common Stock to be received in the Merger as compared to the
illiquidity and lack of marketability of the Company Common Stock and the
dividend history of the Company Common Stock; (v) the tax-free nature of the
Merger for federal income tax purposes which would permit the Company
shareholders who receive shares of Associated Common Stock to defer federal
income taxation under certain circumstances; (vi) the potential for future
appreciation of Associated Common Stock due to Associated's greater market
presence and financial resources and (vii) the financial terms of other recent
business combinations in the financial services industry.  See "The Merger  -
Certain Material Federal Income Tax Consequences."



                                      18

<PAGE>   25
         While each member of the Company's Board of Directors evaluated each
of the foregoing as well as other factors, the Board of Directors collectively
did not assign any specific or relative weights to the factors considered and
did not make any determination with respect to any individual factor.  The
Company's Board of Directors collectively made its determination with respect
to the Merger based on its unanimous conclusion that the Merger, in light of
the factors that each of them individually considered as appropriate, is fair
and in the best interests of the Company's shareholders.

         Associated.  Prior to authorizing the Merger, Associated's Board of
Directors considered, among other things, the improving financial performance
and condition, business operations, capital levels, asset quality and future
growth prospects of the Company.  The Board also considered the benefits to
Associated of expanding in South Central Wisconsin by acquisition of the
Company as opposed to the opening of a new branch bank, the positive impact of
the Merger on Associated by enhancing its visibility in the region and the
terms of the Merger Agreement.

         Associated's Board of Directors believes the Merger will, (i) result
in operational and managerial efficiencies which will better enable the Company
to contain costs and grow more rapidly than historic growth rates; (ii) result
in the Company having greater financial strength, increased competitiveness and
market diversification, thereby also benefiting Associated and its customers;
and (iii) result in an increase in long-term shareholder value for the
shareholders of Associated.

RECOMMENDATIONS OF THE BOARD OF DIRECTORS OF THE COMPANY

         The Board of Directors of the Company has determined that the terms of
the Merger are fair to, and in the best interests of, the Company, and its
shareholders for the reasons stated immediately above.

         THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE
MERGER AGREEMENT AND RECOMMENDS A VOTE FOR APPROVAL OF THE MERGER AGREEMENT.

CERTAIN CONSIDERATIONS

         In deciding whether to vote in favor of the Merger, the Company
shareholders should consider the following factors, in addition to the other
matters set forth herein:

         Anticipated Shareholder Approval of Merger.  Assuming compliance with
the terms of the Voting Agreement and provided the Merger Agreement has not
been terminated prior to its being voted upon by the Company shareholders, the
approval and adoption of the Merger Agreement are assured.  Accordingly,
shareholders of the Company who do not wish to have their shares of Company
Common Stock converted into the right to receive shares of Associated Common
Stock pursuant to the Merger Agreement, must in addition to voting against the
Merger or abstaining from the vote, also exercise Dissenters' Rights.  See "The
Merger - Dissenters' Rights" and Exhibit C hereto.

         Uncertain Legislative and Regulatory Environment.  The banking and
financial services businesses in which the Company and Associated engage are
highly regulated.  The laws and regulations affecting such businesses may be
changed dramatically in the near future.  Such changes could affect the ability
of banks to engage in nationwide branch banking and the ability of bank holding
companies to engage in non-banking businesses, such as securities underwriting
and insurance, in which they have been allowed to engage only on a limited
basis.  Such changes may also affect the capital that banks and bank holding
companies are required to maintain, the premiums paid for or the availability
of deposit insurance or other matters directly affecting earnings.  Neither the
Company nor Associated can predict what changes will occur or the effect that
any such changes would have on the ability of the combined entity to compete
effectively or to take advantage of new opportunities after the Merger.



                                      19

<PAGE>   26


         Competition.  The markets in which the Company and Associated operate
are highly competitive.  Competition in such markets is likely to increase in
light of the changing legislative and regulatory environment in which the
Company and Associated operate.  In addition, consolidation and mergers in the
banking industry are expected to continue, resulting in stronger and more
effective competitors.  Neither the Company nor Associated can predict the
degree to which competition in the industry will increase in the future or the
effect any such increased competition will have on the combined entity.

         Rapid Technological Changes.  Evolving technology will play a major
role in the processing and delivery of financial services.  The effective use
of new technology will enable banking and financial service businesses to
improve information concerning their customers and markets.  It will also
enable them to reduce overhead expenses while improving the quality of service
to customers.  Communications technology will substantially improve the ability
of financial institutions to exchange information with their customers and
employees.  Banks and financial institutions that are unwilling or unable to
access this evolving new technology could experience lower earnings and a loss
of competitiveness.

         Uncertain Economic Environment.  Until recently, banks and financial
service companies in the Midwest have experienced a relatively long period of
price stability and a growing economy.  Price stability enables banks to better
protect themselves against interest rate risks.  A strong economy enhances the
opportunity of the commercial sector of the economy to improve earnings and
performance.  It also provides an environment for financial institutions to
experience positive and profitable growth.  Recent economic changes present
additional risks for all banks and financial service companies.

         Nature of Business.  The financial performance of the Company results
primarily from its retail banking activities located in the City of Portage,
Wisconsin and surrounding markets in South Central Wisconsin.  Company
shareholders who receive shares of Associated Common Stock will own an interest
in a diversified multi-bank holding company with 85 banking offices,
substantially all of which are located in various communities throughout
Wisconsin, which is engaged in several non-banking businesses including
personal property lease financing, commercial and residential mortgage banking,
trust services, reinsurance and general insurance agency activities.  Financial
performance of Associated is accordingly dependent on its activities and the
economic factors in such markets and businesses.  See "Certain Information
Concerning Associated."

         Business Combinations.  Associated seeks additional expansion
opportunities and accordingly may enter into business combinations with banking
and non-banking entities involving the issuance of its shares or payment of
cash consideration which may not require a vote of holders of Associated Common
Stock.

         Share Price Fluctuation.  The price of shares of Company Common Stock
is based upon the financial condition of the Company and the market value for
similar non-publicly traded bank holding companies and other factors.  The
share price of Associated Common Stock on The Nasdaq Stock Market is by 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 Associated.

MERGER CONSIDERATION

         Upon consummation of the Merger, each share of the Company Common
Stock outstanding at the Effective Time will be converted (subject to the
provisions with respect to fractional shares described below) into the right to
receive 1.0665 shares of Associated Common Stock.  See "Certain Provisions of
the Merger Agreement - Termination."

         Based upon the capitalization of Associated and the Company as of the
Record Date, the shareholders of the Company will own Associated Common Stock
representing approximately 5.5% of the outstanding voting shares of Associated
following consummation of the Merger (assuming no exercise of dissenters'
rights).




                                      20
<PAGE>   27


REGULATORY APPROVALS REQUIRED

         Federal.  The Merger is subject to prior approval by the Federal
Reserve Board under the BHC Act, which requires that the Federal Reserve Board
take into consideration, among other factors, the financial and managerial
resources and future prospects of the respective institutions and the
convenience and needs of the communities to be served.  The BHC Act prohibits
the Federal Reserve Board from approving the Merger if it would result in a
monopoly or be in furtherance of any combination or conspiracy to monopolize or
to attempt to monopolize the business of banking in any part of the United
States, or if its effect in any section of the country may be to substantially
lessen competition or to tend to create a monopoly, or if it would in any other
manner be 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.  It is highly improbable that the
Merger poses any antitrust issues.  The Federal Reserve Board also has the
authority to deny an application if it concludes that the combined organization
would have an inadequate capital position.  Furthermore, the Federal Reserve
Board must also assess the records of the bank subsidiaries of Associated and
the Company under the Community Reinvestment Act of 1977, as amended (the
"CRA").  The CRA requires that the Federal Reserve Board analyze, and take into
account when evaluating an application, each bank's record of meeting the
credit needs of its local communities, including low and moderate income
neighborhoods, consistent with safe and sound operation.

         Under the BHC Act, the Merger may not be consummated until up to 30
days following the date of Federal Reserve Board approval, during which time
the United States Department of Justice may challenge the Merger on antitrust
grounds.  Although a challenge is highly improbable, there can be no assurance
that the Department of Justice will not challenge the Merger or, if such a
challenge is made, as to the result thereof.  The commencement of an antitrust
action would stay the effectiveness of the Federal Reserve Board's approval
unless a court specifically orders otherwise.  The BHC Act provides for the
publication of notice and public comment on the applications and authorizes the
regulatory agency to permit interested parties to intervene in the proceedings.

         Associated filed an application with the Federal Reserve Bank of
Chicago (the "Federal Reserve Bank") that was accepted for filing by the
Federal Reserve Bank on December 29, 1995.

         Associated has been advised that the Federal Reserve Bank has accepted
the application for processing under delegated authority from the Federal
Reserve Board on January 29, 1996.  Under the regulations of the Federal
Reserve Board, the Federal Reserve Bank will act on the application within the
30-day period that began on the date the application was accepted for filing (a
period that will be tolled by any public comments or other circumstances that
may trigger further requests for information from the Federal Reserve Bank).
There can be no assurance that the Federal Reserve Bank will continue
processing the application under delegated authority.

         There can be no assurance that the Federal Reserve Board will approve
the Merger, and if the Merger is approved, there can be no assurance as to the
date of such approval.

         Wisconsin.  The Merger is also subject to the prior approval by the
Wisconsin Commissioner of Banking (the "Wisconsin Commissioner") under Section
221.59 of the Wisconsin Statutes which requires that the Wisconsin Commissioner
take into consideration (i) the financial and managerial resources and future
prospects of the respective institutions and whether the transaction would be
contrary to the best interests of the shareholders or customers of the bank or
bank holding company to be acquired; (ii) whether the action would be
detrimental to the safety and soundness of the respective institutions or any
subsidiary or affiliate of the respective institutions; (iii) the record of
performance, management, financial responsibility and integrity, and the CRA
rating of the applicant; and (iv) whether, upon consummation of the
transaction, the applicant would control in excess of 30% of the total amount
of deposits of insured depository institutions in Wisconsin as specified under
federal banking law.

         Associated filed an application with the Wisconsin Commissioner on
January 2, 1996 which was accepted for processing on the date filed.  There can
be no assurance that the Wisconsin Commissioner will approve the Merger, and if
the Merger is approved, there can be no assurance as to the date of such
approval.  The Merger may be consummated at any time within one year of the
date approval was granted by the Wisconsin Commissioner (subject to the
foregoing federal approvals).

         General.  The Merger cannot proceed in the absence of all requisite
regulatory approvals.  See "Conditions to Consummation of the Merger."  In the
Merger Agreement, Associated and the Company have agreed to take all reasonable
actions necessary to comply promptly with all legal requirements which may be
imposed with respect to the Merger, including furnishing information to the
Federal Reserve Board or in connection with approvals or filings with other
governmental entities.  Associated and the Company have also agreed to take all
reasonable action necessary to obtain approvals of the Federal Reserve Board,
the Wisconsin Commissioner and other governmental entities.  However, the
obligation to take reasonable actions is not to be construed as including an
obligation to accept any terms or conditions to an agreement or other approval
of, or any exemption by, any party that are not customarily contained in
approvals of similar transactions granted by such regulators or if Associated
in good faith determines that such terms or conditions would have a material
adverse effect on its business or financial condition or would materially
detract from the value of the Company to Associated.  There can be no assurance
that any regulatory approvals will not contain a term or condition that causes
such approvals to fail to satisfy the conditions described above under
"Conditions to Consummation of the Merger."

         Associated and the Company are not aware of any other governmental
approvals or actions that are required for consummation of the Merger except as
described above.  Should any other approval or action be required, it is
presently contemplated that such approval or action would be sought.  There can
be no assurance that any such approval or action, if needed, could be obtained
and, if such approvals or actions are obtained, there can be no assurance as to
the timing thereof.

THE EFFECTIVE TIME

         The Merger will be consummated and will become effective as of the
date Articles of Merger are filed with the Secretary of State of the State of
Wisconsin (the "Effective Time").  The filing with respect to the Merger will
occur as promptly as practicable after the satisfaction or, if permissible,
waiver of the conditions to the Merger as set forth in the Merger Agreement.
The Merger Agreement may be terminated by either party if, among other reasons,
the Merger shall not have been consummated on or before July 30, 1996.  Upon
consummation of the Merger, the Company will be merged into Holding and will
not continue its separate existence or operations, to which Holding as the
surviving corporation will succeed.  See "Certain Provisions of the Merger
Agreement - Conditions to Consummation of the Merger" and "Certain Provisions
of the Merger Agreement - Termination."

CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES; FRACTIONAL
SHARES

         At the Effective Time and without any action on the part of
Associated, the Company or the holders of the Company Common Stock, each share
of the Company Common Stock issued and outstanding immediately prior to the
Effective Time (other than shares held by Company shareholders exercising their
dissenters' rights under the WBCL) shall be converted into the right to receive
shares of Associated Common Stock.  See "The Merger -  Dissenters' Rights."
All such shares of the Company Common Stock shall no longer be outstanding and
shall automatically be cancelled and retired and shall cease to exist, and each
stock certificate previously representing any such shares of the Company Common
Stock (other than shares held by dissenting shareholders as described above)
shall thereafter represent the right to receive a certificate representing
shares of Associated Common Stock into which such the Company Common Stock has
been converted.  Certificates previously representing shares of the Company
Common Stock shall be exchanged for certificates representing whole shares of
Associated Common Stock upon the surrender of such certificates as provided
below.  No fractional share of Associated Common Stock shall be issued, and, in
lieu thereof, a cash payment shall be made as provided below.



                                      22

<PAGE>   29


         As of the Effective Time, Associated shall deposit, or cause to be
deposited, with Harris Trust and Savings Bank, Chicago, Illinois (the "Exchange
Agent"), for the benefit of the holders of shares of the Company Common Stock
and for exchange in accordance with the terms of the Merger Agreement,
certificates representing the shares of Associated Common Stock (such
certificates for shares of Associated Common Stock to be exchanged for the
Company Common Stock, together with any dividends or distributions with respect
thereto (the "Company Exchange Fund") issuable pursuant to the terms of the
Merger Agreement in exchange for outstanding shares of the Company Common
Stock.

         As soon as reasonably practicable after the Effective Time, the
Exchange Agent shall mail to each holder of record of a certificate which
immediately prior to the Effective Time represented outstanding shares of the
Company Common Stock whose shares were converted into the right to receive
shares of Associated Common Stock, (i) a letter of transmittal and (ii)
instructions for use in effecting the surrender of the Company Certificates in
exchange for certificates representing shares of Associated Common Stock.  Upon
surrender of a certificate previously representing shares of the Company Common
Stock to the Exchange Agent together with such duly executed letter of
transmittal, the holder of such certificate shall receive in exchange therefor
a certificate representing that number of whole shares of Associated Common
Stock to which such holder is entitled and the certificate so surrendered shall
forthwith be cancelled.  In the event of a transfer of ownership of shares
which is not registered in the transfer records of the Company, a certificate
representing the proper number of shares of Associated Common Stock may be
issued to a transferee 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.  Until surrendered, each certificate previously representing
shares of the Company Common Stock shall be deemed at any time after the
Effective Time to represent only the right to receive upon such surrender a
certificate representing shares of Associated Common Stock and cash in lieu of
any fractional shares of Associated Common Stock as described below.

         THE COMPANY SHAREHOLDERS SHOULD NOT FORWARD THEIR STOCK CERTIFICATES
TO THE EXCHANGE AGENT WITHOUT A LETTER OF TRANSMITTAL NOR RETURN THEIR STOCK
CERTIFICATES WITH THE ENCLOSED PROXY.

         No dividends or other distributions declared or made after the
Effective Time with respect to Associated 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 Associated Common Stock represented thereby, and
no cash payment in lieu of fractional shares shall be paid to any such holder,
until such certificate is surrendered.  Subject to the effect of applicable
laws, following surrender of any such certificate, there shall be paid to the
holder of said certificate, which represent whole shares of Associated Common
Stock issued in exchange therefor, without interest, (i) promptly, the amount
of cash payable with respect to a fractional share of Associated Common Stock
to which such holder is entitled and the amount of dividends or other
distributions with a record date after the Effective Time paid with respect to
such whole shares of Associated 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
Associated Common Stock.

         All shares of Associated Common Stock issued upon conversion of the
shares of the Company Common Stock (including any cash paid for fractional
shares) shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of the Company Common Stock.

         No certificates or scrip representing fractional shares of Associated
Common Stock shall be issued upon the surrender for exchange of the
certificates, and such fractional share interest will not entitle the owner
thereof to vote or to any rights of a shareholder of Associated.  Each holder
of a fractional share interest shall be paid an amount in cash equal to the
product obtained by multiplying such fractional share interest to which such
holder would otherwise be entitled by the closing price of a share of
Associated Common Stock as quoted on The Nasdaq Stock Market on the first
business day following the date the Federal Reserve Board issues an order
approving consummation of the Merger.  As soon as practicable after the
determination of the amount of cash, if any, to be



                                      23

<PAGE>   30

paid to holders of fractional share interests, the Exchange Agent shall notify
Associated and Associated shall make available such amounts to such holders of
such factional share interests subject to and in accordance with the terms of
the Merger Agreement, as relevant.

         Any portion of the Exchange Fund which remains undistributed to the
shareholders of the Company for six months after the Effective Time shall be
delivered to Associated, upon demand, and any shareholders of the Company who
have not theretofore complied with the procedures described above shall
thereafter look only to Associated for payment of their claim for Associated
Common Stock, any cash in lieu of fractional shares of Associated Common Stock
and any dividends or distributions with respect to Associated Common Stock.

         Neither Associated nor the Company shall be liable to any holder of
shares of the Company Common Stock for any such shares of the Company Common
Stock (or dividends or distributions with respect thereto) or cash delivered to
a public official pursuant to any abandoned property, escheat or similar law.

         Associated shall be entitled to deduct and withhold from any cash
consideration payable pursuant to the Merger Agreement to any holder of shares
of the Company Common Stock such amounts as Associated is required to deduct
and withhold with respect to the making of such payment under the Internal
Revenue Code of 1986, as amended (the "Code"), or any provision of state, local
or foreign tax law.

         At the Effective Time, the stock transfer books of the Company shall
be closed, and there shall be no further registration of transfers of shares of
the Company Common Stock, thereafter on said record books.  From and after the
Effective Time, the holders of certificates shall cease to have any rights with
respect to such shares of the Company Common Stock except as otherwise provided
in the Merger Agreement, or by law.  On or after the Effective Time, any
certificates presented to the Exchange Agent or Associated for any reason shall
be converted into shares of Associated Common Stock in accordance with the
terms of the Merger Agreement as described above.

DESCRIPTION OF ASSOCIATED COMMON STOCK ISSUABLE IN THE MERGER

         The following description of Associated Common Stock issuable in the
Merger is a summary and is qualified in its entirety by reference to the terms
of such security, which is incorporated by reference herein and is set forth in
full in Article III of Associated's Articles of Incorporation (the "Associated
Articles").  The description set forth below is subject in all respects to the
WBCL and the Associated Articles.

         Harris Trust and Savings Bank is the transfer agent and registrar for
all outstanding Associated Common Stock.

         THE FOLLOWING DESCRIPTION OF ASSOCIATED COMMON STOCK SHOULD BE READ
CAREFULLY BY THE COMPANY SHAREHOLDERS SINCE, AT THE EFFECTIVE TIME, EACH ISSUED
AND OUTSTANDING SHARE OF THE COMPANY COMMON STOCK WILL BE CONVERTED INTO THE
RIGHT TO RECEIVE SHARES OF ASSOCIATED COMMON STOCK AT THE EXCHANGE RATIO.

         General.  Associated has one class of common stock, the Associated
Common Stock.  Of the 48,000,000 shares of Associated Common Stock authorized,
16,518,145 shares were outstanding as of the Record Date, exclusive of shares
held in its treasury.  Of the 750,000 shares of Associated preferred stock with
a par value of $1.00 per share authorized, none were issued and outstanding as
of the Record Date.

         Dividend Rights.  Dividends on Associated Common Stock will be payable
out of the assets of Associated legally available therefor as, if and when
declared by the Associated Board of Directors.  No share of Associated Common
Stock is entitled to any preferential treatment with respect to dividends.



                                      24

<PAGE>   31

         Voting Rights.  Each holder of Associated Common Stock will be
entitled at each shareholders' meeting of Associated, as to each matter to be
voted upon, to cast one vote, in person or by proxy, for each share of
Associated Common Stock registered in his or her name on the stock transfer
books of Associated.  Such voting rights are not cumulative.

         Rights Upon Liquidation.  Subject to the rights of holders of any
Associated preferred stock which may be issued from time to time, in the event
of liquidation, dissolution or winding up of Associated, whether voluntary or
involuntary, the holders of Associated Common Stock will be entitled to receive
all assets of Associated remaining for distribution to its shareholders, on a
pro rata basis.

         Miscellaneous.  Shares of Associated Common Stock are not convertible
into shares of any other class of capital stock.  Shares of Associated Common
Stock are not and will not be entitled to any preemptive or subscription
rights.  The issued and outstanding shares of Associated Common Stock are fully
paid and nonassessable (except as otherwise provided under the WBCL).

COMPARISON OF SHAREHOLDER RIGHTS

         The following is a summary of material differences between the rights
of holders of Company Common Stock and Associated Common Stock.  As the Company
and Associated are both incorporated under the laws of the State of Wisconsin,
rights of shareholders are substantially similar.  Differences in the rights of
shareholders of the Company and Associated arise from differences between the
provisions of the Associated Articles and By-laws and those of the Company.
Shareholders of the Company, whose rights are governed by the Company's
Articles of Incorporation, By-laws and the WBCL will, on consummation of the
Merger, become shareholders of Associated.  Their rights as Associated
shareholders will then be governed by Associated's Articles of Incorporation
and By-laws and by the WBCL.  The following is a summary of the material
differences between the rights of shareholders of the Company and the rights of
shareholders of Associated.

         AUTHORIZED CAPITAL STOCK

         The Company.  Under the Company's Articles of Incorporation, the
aggregate number of shares which it is authorized to issue is 2,000,000 shares
of one class of common stock, $1.00 par value.  All shares of the Company
Common Stock are identical in rights and have one vote.  The holders of the
Company Common Stock are entitled to such dividends as may be declared from
time to time by the Board of Directors of the Company from funds available
therefor and upon liquidation are entitled to receive pro rata all assets of
the Company available for distribution to such holders.  The Company has no
authorized shares of preferred stock and, accordingly, the rights of holders of
Company Common Stock to receive dividends or payment in the event of voluntary
or involuntary dissolution, liquidation or winding up of the Company are not
subject to the prior satisfaction of the rights of any other shareholders.

         Associated.  Under Associated's Articles of Incorporation, Associated
is authorized to issue 48,000,000 shares of common stock, par value $0.01 per
share and 750,000 shares of preferred stock, $1.00 par value.  All shares of
Associated Common Stock are identical in rights and have one vote.  For a
description of Associated Common Stock, see "Description of Associated Common
Stock Issuable in the Merger."  The preferred stock shall be cumulative and
dividends shall accrue thereon.  The Board of Directors may divide the
preferred stock into series and establish the relative rights and preferences
of preferred stock issued in the future as specified in the Articles without
shareholder action and issue such stock in series.  As of the date hereof, no
shares of any series of Associated preferred stock are issued and outstanding.



                                      25

<PAGE>   32

         APPRAISAL RIGHTS AND DISSENTERS' RIGHTS

         The Company.  Under the WBCL, a shareholder of a corporation is
generally entitled to receive payment of the fair value of such shareholder's
stock if such shareholder dissents from a proposed merger or share exchange or
a sale or exchange of all or substantially all of the property and assets of
the corporation.

         Associated.  Dissenters' rights under the WBCL are not available to
holders of shares, such as shares of Associated Common Stock, which are
registered on a national securities exchange or quoted on Nasdaq on the record
date fixed to determine shareholders entitled to notice of the meeting at which
shareholders are to vote on the proposed corporate action.  Associated Common
Stock is quoted on The Nasdaq Stock Market.

         REQUIRED VOTE

         The Company.  Pursuant to the WBCL, the affirmative vote of a majority
of the shares of the Company Common Stock is required to adopt amendments to
the Company's Articles of Incorporation or approve mergers and certain other
extraordinary transactions.

         Associated.  Pursuant to 180.1706(1) of the WBCL, except as otherwise
provided in a corporation's articles of incorporation or bylaws, any amendment
to the articles of incorporation, merger or certain other extraordinary events
involving a corporation organized before January 1, 1973, which did not
expressly elect before January 1, 1991 to be governed by a majority or greater
voting requirement, must be approved by the affirmative vote of two-thirds of
the shares entitled to vote at a meeting called for that purpose.  The
Associated articles were amended in 1992 to reduce the vote required pursuant
to Section 180.1706(1) of the WBCL to a majority vote.  Thus, the affirmative
vote of a majority of the shares of Associated is required to adopt amendments
to the Associated Articles which create dissenters' rights or approve mergers
and certain other extraordinary transactions other than those in "Comparison of
Shareholder Rights - Takeover Provisions."

         CLASSIFIED BOARD OF DIRECTORS

         The Company.  The Company's Board of Directors consists of a single
class of directors, not less than five nor more than twenty-five in number.
The Company currently has seven directors, each of whom serves for one year or
until his or her successor is elected and qualified.  The By-laws require that
a director resign from the Board on the first day of the month in which such
director attains the age of 72 years.

         Associated.  The Board of Directors of Associated is divided into
three classes as nearly equal in number as possible, with the directors in each
class serving for staggered three-year terms.  However, the By-laws require
that a director retire as of the first annual meeting of shareholders
subsequent to the director's 65th birthday unless such director's term is
extended for a one-year term by a two-thirds vote of Associated's Board.  At
each annual meeting of Associated's shareholders, the successors to the class
of directors whose term expires at the time of such meeting are elected by a
majority of the votes cast, assuming a quorum is present.  Associated's Board
consists of ten directors.

         REMOVAL OF DIRECTORS FOR "CAUSE"

         The Company.  The Company's By-laws provide that a director may be
removed from office "with or without cause" by a vote of shareholders where the
votes cast to remove the director exceed the number of votes cast not to remove
the director.

         Associated.  Shareholders of Associated may remove a director only for
"cause."  "Cause" is defined as conviction of a felony, declaration of unsound
mind by an order of a court of competent jurisdiction, gross



                                      26

<PAGE>   33

dereliction of duty or commission of an action which constitutes intentional
misconduct or a knowing violation of law and that results in both an improper
substantial personal benefit and a material injury to Associated.

         NEWLY CREATED DIRECTORSHIPS AND VACANCIES ON THE BOARD OF DIRECTORS

         The Company.  Pursuant to 180.0810 of the WBCL, unless otherwise
provided in a corporation's Articles, shareholders may fill vacancies on a
corporation's Board of Directors.  The Company's By-laws authorize the Board of
Directors by the affirmative vote of the directors then in office, though less
than a quorum, to fill vacancies on the Company's Board of Directors until the
next succeeding election of directors.  In the case of a vacancy created by the
removal of a director by vote of shareholders, the shareholders shall have the
right to fill such vacancy.

         Associated.    The Associated's Articles provide that newly created
directorships and any vacancies on Associated's Board of Directors may only be
filled by the Board of Directors.  Associated's By-laws provide that the
remaining members of the Board shall appoint a director in accordance with the
WBCL.

         CERTAIN BUSINESS COMBINATIONS

         The Company.  The Company's Articles of Incorporation and By-laws do
not contain any supermajority voting provisions relating to the approval by
holders of the Company Common Stock of mergers or other business combinations.

         Associated.  Article VII of Associated's Articles provides that an
affirmative vote of 80% of Associated's outstanding shares is required to
approve a merger or other business combination involving a beneficial owner of
10% or more of Associated's outstanding voting shares (an "interested
shareholder").  In addition, if the consideration offered in connection with
such transaction does not satisfy certain "fair price" requirements, the
affirmative vote of 80% of the "non-interested outstanding shares" (defined as
voting shares not beneficially owned by an interested shareholder) of
Associated will also be required to approve such a transaction.  These
requirements do not apply if (a) the board of directors approves the
transaction and a majority of the directors voting to approve the transaction
are "continuing directors" (defined as a director who was either (i) a director
at the time the interested shareholder became "interested" and who is not
otherwise affiliated with such shareholder, or (ii) a director designated
(prior to his or her initial election as a director) as a continuing director
by a majority of the then continuing directors) or (b) the transaction is
between Associated and a subsidiary of Associated and no interested shareholder
(together with such shareholder's affiliates and associates) owns any of the
outstanding shares of the subsidiary.  The foregoing provision may only be
amended, modified or repealed by the affirmative vote of not less than 80% of
the outstanding shares and the non-interested outstanding shares of Associated.

         ADVANCE NOTICE OF PROPOSALS TO BE BROUGHT AT THE ANNUAL MEETING

         The Company.  The Company's Articles and By-laws do not contain any
provisions relating to advance notice of proposals to be brought before an
annual meeting.

         Associated.  Pursuant to Article II, Section 5 of Associated's
By-laws, any shareholder who intends to bring business before an annual meeting
of shareholders (other than nominations for directors) must provide Associated
with notice of such intention, the nature of such proposal and certain other
information regarding the shareholder bringing the proposal, not less than 60
nor more than 75 days prior to the meeting, or within 10 days from the date
notice or public disclosure of the date of such meeting is given, if such
announcement date is less than 70 days before the meeting date.

<PAGE>   34
RESALE OF ASSOCIATED COMMON STOCK ISSUED PURSUANT TO THE MERGER

         The Associated Common Stock issued pursuant to the Merger will be
registered under the Securities Act and be freely tradeable under the
Securities Act except for shares issued to any shareholder of the Company who
may be deemed to be an "affiliate" of the Company for purposes of Rule 145
under the Securities Act.  Each affiliate identified by the Company will enter
into an agreement with Associated providing that such affiliate will be subject
to Rule 145(d) of the Securities Act, shall not transfer any Associated Common
Stock received in the Merger except in compliance with the Securities Act.  In
order to comply with pooling of interests requirements, such persons shall
agree to make no disposition of any shares of the Company Common Stock or
Associated Common Stock (or any interests therein) during the period beginning
30 days before the Effective Time and ending when the financial results for at
least 30 days of combined operations of the Company and Associated after the
Effective Time have been published.  This Proxy Statement/Prospectus does not
cover resales of Associated Common Stock received by any person who may be
deemed to be an affiliate of the Company.

PRE-MERGER DIVIDEND POLICY

         The Company.  Pursuant to the Merger Agreement, except for a quarterly
dividend commencing February 15, 1996 not to exceed $0.32 per share, the
Company is prohibited from declaring or paying any dividend on, or making any
other distribution in respect of, its outstanding shares of capital stock
without the prior written consent of Associated.  The Company does not
anticipate paying any other dividends on shares of the Company Common Stock
prior to the Effective Time.

         Associated.  Associated expects to continue to declare, until the
Effective Time, its regularly scheduled dividends.

POST-MERGER DIVIDEND POLICY

         It is the current intention of the Board of Directors of Associated to
continue to declare cash dividends on the Associated Common Stock following the
Merger.  The dividend is currently in the amount of $0.27 per quarter or $1.08
per year, in each case per share.  Shareholders should note that no such
dividends payable following the date hereof have currently been declared and
that future dividends will be determined by the Associated Board of Directors
in light of the earnings and financial condition of Associated and its
subsidiaries and other factors, including applicable governmental regulations
and policies.  In that regard, Associated is a legal entity separate and
distinct from its banking and non-banking subsidiaries, and the principal
sources of Associated's income are dividends and interest from such
subsidiaries.  The payment of dividends by Associated's banking subsidiaries is
subject to certain restrictions under applicable governmental regulations.  See
also "The Merger - Pre-Merger Dividend Policy."

CONDUCT OF BUSINESS PENDING THE MERGER

         Pursuant to the Merger Agreement, the Company has agreed to carry on
its business, and the business of its subsidiaries, in the usual, regular and
ordinary course in substantially the same manner as conducted prior to the
execution of the Merger Agreement, subject to certain covenants and other
agreements agreed to by the Company in the Merger Agreement.  See "Certain
Provisions of the Merger Agreement - Certain Covenants."

CERTAIN MATERIAL FEDERAL INCOME TAX CONSEQUENCES

         Associated and the Company have received an opinion of KPMG Peat
Marwick LLP that the Merger will qualify as a tax-free reorganization under
Section 368(a)(1)(A) of the Code and that each of Associated and the Company
will be a party to such reorganization within the meaning of Section 368(b) of
the Code.  Accordingly, the Company, Associated and Holding will recognize no
gain or loss for federal income tax purposes as a result



                                      28

<PAGE>   35

of the Merger and no gain or loss will be recognized by any holder of the
Company Common Stock upon receipt of Associated Common Stock pursuant to the
Merger (except upon the receipt of cash in lieu of fractional shares of
Associated Common Stock).  This discussion of federal income tax consequences
of the Merger assumes that none of the holders of Company Common Stock will
exercise dissenters' rights.  The Internal Revenue Service ("Service") has not
been asked to rule upon the tax consequences of the Merger and such request
will not be made.  The opinion of KPMG Peat Marwick LLP is based entirely upon
the Code, regulations now in effect thereunder, current administrative rulings
and practice, and judicial authority, all of which are subject to change.
Unlike a ruling from the Service, an opinion of an advisor is not binding on
the Service and there can be no assurance, and none is hereby given, that the
Service will not take a position contrary to one or more positions reflected
herein or that the opinion will be upheld by the courts if challenged by the
Service.

EACH SHAREHOLDER OF THE COMPANY IS URGED TO CONSULT HIS OR HER OWN TAX AND
FINANCIAL ADVISORS AS TO THE EFFECT OF SUCH FEDERAL INCOME TAX CONSEQUENCES ON
HIS OR HER OWN PARTICULAR FACTS AND CIRCUMSTANCES AND ALSO AS TO ANY STATE,
LOCAL, FOREIGN OR OTHER TAX CONSEQUENCES ARISING OUT OF THE MERGER.

         Based upon the opinion of KPMG Peat Marwick LLP, which in turn is
based upon various representations and subject to various assumptions and
qualifications, the following federal income tax consequences to the
shareholders of the Company will result from the Merger:

                 (i)      Provided that the Merger of the Company with and into
         Holding qualifies as a statutory merger under applicable law, the
         Merger will qualify as a reorganization within the meaning of Sections
         368(a)(1)(A) and 368(a)(2)(D) of the Code, and the Company, Associated
         and Holding will each be "a party to a reorganization" within the
         meaning of Section 368(b) of the Code for purposes of this
         reorganization.

                 (ii)     No gain or loss will be recognized by the holders of
         the Company Common Stock upon the exchange of the Company Common Stock
         solely for Associated Common Stock pursuant to the Merger, except with
         respect to cash received in lieu of fractional shares of Associated
         Common Stock.

                 (iii)    A Company shareholder's aggregate basis in the
         Associated Common Stock (including any fractional share interest to
         which he or she may be entitled) received in the Merger will be the
         same as the aggregate basis of the Company Common Stock exchanged
         therefor.

                 (iv)     The holding period of the Associated Common Stock
         received by a holder of Company Common Stock pursuant to the Merger
         will include the period during which the Company Common Stock
         exchanged therefor was held, provided that the Company Common Stock
         surrendered was held as a capital asset as of the time of the Merger.

                 (v)      The receipt by a holder of Company Common Stock of
         cash in lieu of a fractional share of Associated Common Stock will be
         treated as if he or she received such fractional share from Associated
         and then had it redeemed for cash.  Such receipt of cash will be
         treated under Section 302(b)(1) of the Code as full payment in
         exchange for the fractional share.

         The foregoing is only a general description of certain material
federal income tax consequences of the Merger for holders of the Company Common
Stock who are citizens or residents of the United States and who hold their
shares as capital assets, without regard to the particular facts and
circumstances of the tax situation of each holder of the Company Common Stock.
It does not discuss all of the consequences that may be relevant to holders of
the Company Common Stock entitled to special treatment under the Code (such as
insurance companies, financial institutions, dealers in securities, tax-exempt
organizations or foreign persons).  The summary set forth above does not
purport to be a complete analysis of all potential tax effects of the
transactions contemplated by the Merger




                                      29
<PAGE>   36

Agreements or the Merger itself.  No information is provided herein with
respect to the application and effect of state, local and foreign tax laws and
the possible effects of changes in federal laws or other tax laws.

ANTICIPATED ACCOUNTING TREATMENT

         The business combination resulting from the Merger is expected to
qualify as a "pooling of interests" for accounting and financial reporting
purposes.  Under this method of accounting, the recorded assets and liabilities
of Associated and the Company will be carried forward to the combined
corporation at their recorded amounts; income of the combined corporation will
include income of Associated and the Company for the entire fiscal year in
which the combination occurs.

         The Merger Agreement provides that a condition to the consummation of
the Merger is the receipt of the opinion of the independent public accountants
of Associated to the effect that the Merger qualifies for "pooling of
interests" accounting treatment.  IN THE EVENT SUCH CONDITION IS NOT MET, THE
MERGER WOULD NOT BE CONSUMMATED UNLESS THE CONDITION WERE WAIVED BY ASSOCIATED.

DISSENTERS' RIGHTS

         Under the provisions of Subchapter XIII of the WBCL, a copy of which
is attached to this Proxy Statement/Prospectus as Exhibit C and which
provisions are incorporated herein by reference, any holder of record or
beneficial holder of Company Common Stock has the right to dissent from the
Merger and demand payment of the "fair value" of his or her shares in cash as
determined pursuant to Subchapter XIII of the WBCL ("Dissenters' Rights").  Set
forth below is a summary of the procedures relating to the exercise of
Dissenters' Rights.  This summary does not purport to be a complete statement
of the provisions of Subchapter XIII of the WBCL.  Any shareholder who wishes
to assert Dissenters' Rights must deliver a written notice of his or her intent
to exercise such right to Greater Columbia Bancshares, Inc., 222 East Wisconsin
Street, Portage, Wisconsin 53901, Attention Ms. Mary E. Coddington, Secretary,
before the vote on the Merger Agreement is taken at the special meeting.  A
PROXY OR VOTE AGAINST THE MERGER AGREEMENT WILL NOT, BY ITSELF, BE REGARDED AS
A WRITTEN NOTICE OF INTENT TO DEMAND PAYMENT FOR PURPOSES OF ASSERTING
DISSENTERS' RIGHTS.

         A record holder of Company Common Stock may assert Dissenters' Rights
as to fewer than all shares registered in that shareholder's name only if the
holder dissents with respect to all shares beneficially owned by any one person
and notifies the Company in writing of the name and address of each person on
whose behalf the shareholder asserts such Dissenters' Rights.

         A beneficial shareholder may assert Dissenters' Rights as to shares
held on the shareholder's behalf only if, in addition to meeting the other
requirements to dissent, the beneficial shareholder (i) submits to the Company
the record shareholder's written consent to the dissent not later than the time
the beneficial shareholder asserts Dissenters' Rights and (ii) asserts
Dissenters' Rights with respect to all shares of which the shareholder is the
beneficial shareholder or over which the beneficial shareholder has power to
direct the vote.

         If the Merger Agreement is approved by the requisite vote of holders
of the Company Common Stock, the Company is required to send a notice (the
"Dissenters' Notice") to all dissenting shareholders containing payment demand
and stock certificate surrender information (the "Payment Demand") within 10
days after such approval.  The return date (the "Payment Demand Date")
specified by the Company for receiving the Payment Demand from dissenting
shareholders may not be less than 30 nor more than 60 days after the date on
which the Dissenters' Notice was first sent.  Upon receipt of the Dissenters'
Notice, each dissenting shareholder must return his Payment Demand and
Certificate no later than the Payment Demand Date as provided in the
Dissenters' Notice and certify whether he or she acquired beneficial ownership
of the shares prior to the first public announcement of the terms of the Merger
on August 24, 1995.  A Payment Demand may not be withdrawn without the
Company's consent.



                                      30

<PAGE>   37

         Upon effecting the Merger, within 60 days after the Payment Demand
Date, the Company will pay each dissenting shareholder who properly complied
with the statutory requirements of Subchapter XIII of the WBCL, the amount that
the Company estimates to be the fair value of such dissenting shareholder's
shares, plus accrued interest from the Effective Time; provided that, with
respect to shares acquired after the first public announcement of the Merger,
the Company may elect to withhold payment until either such shareholder accepts
the Company's offer of fair value or a court determines the fair value of such
shares.

         If the Merger is not effected within 60 days of the Payment Demand
Date, the Company will return all deposited certificates to dissenting
shareholders.  If the Merger is thereafter effected, the Company will send a
new Dissenters' Notice within 10 days of effecting the Merger and repeat the
payment demand procedure described above.

         If any dissenting shareholder is dissatisfied with the Company's
determination of "fair value," such dissenting shareholder may notify the
Company in writing of his or her own estimate of the fair value of his or her
shares and the amount of interest due.  A dissenting shareholder must assert
this right within 30 days after the Company makes or offers payment for his or
her shares or the right is waived.  The Company may either accept such
dissenting shareholder's estimate of fair value or commence a proceeding in the
Wisconsin Circuit Court of Columbia County to determine the fair value of the
shares of all dissenting shareholders whose own estimates of fair value are not
accepted by the Company.

         In the event any holder of the Company Common Stock fails to perfect
his or her rights to dissent by failing to comply strictly with the applicable
statutory requirements of Subchapter XIII of the WBCL, he or she will be bound
by the terms of the Merger Agreement and will not be entitled to payment for
his or her shares under Subchapter XIII of the WBCL.  ANY HOLDER OF COMPANY
COMMON STOCK WHO WISHES TO OBJECT TO THE TRANSACTION AND DEMAND PAYMENT IN CASH
FOR HIS OR HER SHARES SHOULD CONSIDER CONSULTING HIS OR HER OWN LEGAL ADVISOR.

         Because an executed proxy relating to Company Common Stock on which no
voting direction is made will be voted at the Special Meeting in favor of the
Merger, a dissenting shareholder who wishes to have his or her shares of
Company Common Stock represented by proxy at the Special Meeting but preserve
his or her dissenters' rights must mark his or her proxy either to vote against
the Merger or to abstain from voting thereon, in addition to the foregoing
requirements.

INTERESTS OF CERTAIN PERSONS IN THE MERGER

         Associated (through the Bank as employer) will enter into an
Employment and Non-Competition Agreement with Mr.  Pascavis providing for the
employment of Mr. Pascavis by the Bank as President and Chief Executive Officer
of the Bank or in such other management capacity as may be determined by
Associated, for the period commencing on the Effective Time of the Merger and
continuing, unless sooner terminated as provided in the agreement, until the
second anniversary of said date.  Pursuant to the agreement, Mr. Pascavis will
receive an annual base salary of $120,000 together with employee benefits
generally made available to the President by the Bank.  In addition, Mr.
Pascavis shall have the opportunity to participate in a discretionary bonus
plan established by Associated and shall have the opportunity to earn an annual
bonus of up to 25% of his annual base salary.  Upon the termination of Mr.
Pascavis' employment, in addition to any other retirement benefits payable, Mr.
Pascavis will be paid a supplemental retirement annuity of $25,000 per year for
ten years payable monthly.  During the term of the agreement, unless terminated
pursuant to its provisions prior thereto, and for two years following the
termination of the agreement, Mr. Pascavis has agreed not to compete with any
commercial banking operations of the Bank within 50 miles of the Bank's main
banking office.

THE VOTING AGREEMENT

         Pursuant to the Voting Agreement, attached hereto as Exhibit B, the
execution of which was a condition to Associated entering into the Merger
Agreement, the directors of the Company have agreed to vote their shares (i) in
favor of the adoption and approval of the Merger Agreement and the Merger and
(ii) against any Competing Transaction.  The Voting Agreement also provides
that Associated has the exclusive right to purchase any or all of the shares of
Company Common Stock owned by the directors for $37.3275 per share, payable in
cash, subject to any necessary regulatory approval, after a material breach of
the Merger Agreement by the Company or any events or circumstances that lead
Associated reasonably to believe that the Company is likely to materially
breach the Merger Agreement, a breach by a Party Shareholder, or the
acquisition or overtly threatened acquisition of 5% of the stock or a material
portion of the assets of the Company or the Bank.  The purchase right is not
exercisable as of the date hereof.  The purchase price per share under the
Voting Agreement equalled the value of the Company Common Stock based upon the
trading price of Associated Common Stock at the date that the Voting Agreement
was requested by Associated.  See "Certain Provisions of the Voting Agreement."

         Anti-Takeover Effect of the Voting Agreement.  The Voting Agreement
may have the effect of discouraging persons who might now or in the future be
interested in acquiring all of or a significant interest in the Company from
considering or proposing such an acquisition, even if such persons were
prepared to pay a higher price per share for the Company Common Stock than the
price per share implicit in the Exchange Ratio.  Certain attempts to acquire
the Company or an interest in the Company would cause Associated's right to
purchase such shares and to receive any premium offered to the directors of the
Company.

OTHER RELATED PARTY TRANSACTIONS

         In the ordinary course of conducting their banking and financial
services businesses, each of Associated, the Company and their respective
subsidiaries, may do business and engage in banking transactions with the other
party and its subsidiaries, which may include but not be limited to interests
or participation in loans and interbank advances.

MANAGEMENT AFTER THE MERGER

         In the Merger, the Company will be merged into Holding and the
separate corporate existence of the Company will cease.  Associated will
thereby acquire control of the Bank through Holding and the Bank will operate
under the name "Associated Bank Portage."

         The officers and directors of Holding prior to the Merger will
continue as officers and directors of the surviving corporation.  The directors
of the Bank prior to the Effective Time will continue as directors after the
Effective Time until their successors shall have been duly elected and
qualified.

                   CERTAIN PROVISIONS OF THE MERGER AGREEMENT

         The following is a brief summary of certain provisions of the Merger
Agreement, which is attached as Exhibit A to this Proxy Statement/Prospectus
and is incorporated herein by reference.  Such summary is qualified in its
entirety by reference to the Merger Agreement.

THE MERGER

         The Merger Agreement provides that, following the approval of the
Merger Agreement by the shareholders of the Company and the satisfaction or
waiver of the other conditions to the Merger, the Company will be merged with

the Company, the Merger will become effective upon the Effective Time.

NO SOLICITATION OF TRANSACTIONS

         The Merger Agreement provides that the Company and its respective
subsidiaries will not initiate, solicit or encourage (including by way of
furnishing information or assistance), or take any other action to facilitate,
any inquiries or the making of any proposal that constitutes, or may reasonably
be expected to lead to any Competing Transaction or negotiate with any person
in furtherance of such inquiries or to obtain a Competing Transaction, or agree
to or endorse any Competing Transaction, or authorize or permit any of its
officers, directors or employees





                                      34
<PAGE>   41

or any investment banker, financial advisor, attorney, accountant or other
representative retained by it or any of its subsidiaries to take any such
action.  The Company must promptly notify Associated orally and in writing of
all of the relevant details relating to all inquiries and proposals which it
may receive relating to any of such matters.  Notwithstanding the foregoing,
the Board of Directors of the Company is not prohibited from (i) furnishing or
permitting any of its officers, directors, employees, investment bankers,
financial advisors, attorneys, accountants or other representatives to furnish
information to any party that requests information as to the Company if the
Board of Directors of the Company, after consultation with and based upon the
written advice of independent legal counsel, determines in good faith that such
action is required for the Board of Directors of the Company to comply with its
fiduciary duties to shareholders imposed by law, and if prior to furnishing
such information to such party, the Company receives from such party an
executed confidentiality agreement in reasonably customary form.

         For purposes of the Merger Agreement, a "Competing Transaction" shall
mean any of the following involving the Company or any of the Company's
subsidiaries: (i) any merger, consolidation, share exchange, business
combination, or other similar transactions; (ii) any sale, lease, exchange,
mortgage, pledge, transfer or other disposition of 10% or more of assets in a
single transaction or series of transactions, excluding from the calculation of
such percentage any such transactions undertaken in the ordinary course of
business and consistent with past practice; (iii) any sale of 10% or more of
shares of capital stock (or securities convertible or exchangeable into or
otherwise evidencing, or any agreement or instrument evidencing, the right to
acquire capital stock); (iv) any tender offer or exchange offer for 10% or more
of outstanding shares of capital stock; (v) any solicitation of proxies in
opposition to approval by the Company's shareholders of the Merger; (vi) the
filing of an acquisition application (or the giving of acquisition notice)
whether in draft or final form under the BHC Act or the Change in Bank Control
Act with respect to the Company or its subsidiaries; (vii) any person shall
have acquired beneficial ownership or the right to acquire beneficial ownership
of, or any "group" (as such term is defined under Section 13(d) of the Exchange
Act and the rules and regulations promulgated thereunder) shall have been
formed which beneficially owns or has the right to acquire beneficial ownership
of, 10% or more of the then outstanding shares of capital stock; or (viii) any
public announcement of a proposal, plan or intention to do any of the
foregoing.

cured within 10 business days following receipt by the non-terminating party of
notice of such breach or other condition (provided that the Merger Agreement
may not be terminated by the breaching party or party making any representation
or warranty which shall have become untrue in any material respect); (iii) by
either Associated or the Company if any permanent injunction preventing the
consummation of the Merger shall have become final and nonappealable; (iv) by

Commissioner denied approval of the Merger and neither Associated nor the
Company has, within 30 days after the entry of such order denying approval,
filed a petition seeking review of such order as provided by applicable law;

into which would reduce the amount or change the consideration into which each
share of the Company Common Stock shall be converted upon consummation of the

for filing the Registration Statement and this Proxy Statement/Prospectus and
all Commission and other regulatory filing fees incurred in connection with the

                   CERTAIN PROVISIONS OF THE VOTING AGREEMENT

         The following is a brief summary of certain provisions of the Voting
Agreement, which is attached as Exhibit B to this Proxy Statement/Prospectus
and is incorporated herein by reference.  The following summary is qualified in
its entirety by reference to the Voting Agreement.

         Associated has entered into the Voting Agreement with directors of the
Company.  The directors hold 596,935 shares representing approximately 65.8% of
the total voting power of Company Common Stock.  The Voting Agreement provides
that the directors, in consideration of the substantial expenses incurred by
Associated in connection with the Merger Agreement and as a condition to
Associated entering into the Merger Agreement, shall vote or cause to be voted
or express a written consent with respect to all of such director's shares:

                 (a)      in favor of adoption and approval of the Merger
         Agreement and the Merger at every meeting of shareholders of the
         Company at which such matters are considered and at every adjournment
         thereof and in connection with every proposal to take action by
         written consent with respect thereto, and

                 (b)      against any other Competing Transaction at every
         meeting of shareholders of the Company at which such matters are
         considered and at every adjournment thereof and in connection with
         every proposal to take action by written consent with respect thereto.

         The Voting Agreement also provides that Associated has the exclusive
right to purchase any or all of the shares of Company Common Stock owned by
each director for $37.3275 per share, payable in cash, subject to any necessary
regulatory approval, after a material breach of the Merger Agreement by the
Company or any events or circumstances that lead Associated reasonably to
believe that the Company is likely to materially breach the Merger Agreement, a
breach by a director, or the acquisition or overtly threatened acquisition of
5% of the stock or a material portion of the assets of the Company or the Bank.
The purchase right is not exercisable as of the date hereof.  The purchase
price per share under the Voting Agreement equalled the value of the Company
Common



                                      37

<PAGE>   44

Stock based upon the trading price of Associated Common Stock at the date that
the Voting Agreement was requested by Associated.

         The Voting Agreement also provides that:

                 (a)      Each of the directors agrees that such director will
         not, nor will such director permit any entity under such director's
         control, to deposit any of such director's shares in a voting trust or
         subject any of their shares to any agreement, arrangement or
         understanding with respect to the voting of such shares inconsistent
         with the Voting Agreement.

                 (b)      During the term of the Voting Agreement, each
         director agrees not to sell, assign, transfer or dispose of such
         director's shares.

         The Voting Agreement shall terminate upon the earlier of (a) the
Effective Time of the Merger and (b) the date on which the Merger Agreement is
terminated in accordance with its terms.  Upon such termination, no party shall
have any further obligations or liabilities under the Voting Agreement;
provided that termination shall not relieve any party from liability for any
breach of the Voting Agreement prior to such termination.

         The Voting Agreement binds the actions of the signatories thereto only
in their capacity as shareholders of the Company, and such
shareholders/directors of the Company were not and could not be contractually
bound to abrogate their fiduciary duties as directors of the Company.
Accordingly, while such shareholders/directors are, under the Voting Agreement,
contractually bound to vote as a shareholder in favor of the Merger and against
a Competing Transaction should one be presented, their fiduciary duties as
directors nevertheless require them to act, in their capacity as directors, in
the best interests of the Company when they decided to approve and adopt the
Merger Agreement.  In addition, such shareholders/directors will continue to be
bound by their fiduciary duties as directors of the Company with respect to any
decisions they may take in connection with the Merger of otherwise.

         Assuming compliance with the terms of the Voting Agreement, and
provided the Merger Agreement has not been terminated prior to its being voted
upon by the shareholders of the Company, the approval and adoption of the
Merger Agreement are assured.

services including the origination, underwriting, closing, and the temporary

         AGREEMENT AND PLAN OF MERGER, dated as of December 22, 1995 (the
"Agreement"), among ASSOCIATED BANC-CORP, a Wisconsin corporation
("Associated"), ASSOCIATED BANC-SHARES, INC., a Wisconsin corporation
("Holding") and GREATER COLUMBIA BANCSHARES, INC., a Wisconsin corporation

                              W I T N E S S E T H:

         WHEREAS, the Company is a bank holding company, the wholly-owned
subsidiary of which is The First National Bank of Portage, a national bank
located in Portage, Wisconsin (the "Bank");  and

         WHEREAS, the Bank has only one wholly-owned subsidiary, Portage
Investments, Inc. ("Portage").  The Bank and Portage are sometimes individually
referred to herein as a "Subsidiary" and collectively as the "Subsidiaries;"
and

         WHEREAS, the Company upon the terms and subject to the conditions of
this Agreement and in accordance with the Wisconsin Business Corporation Act
("Wisconsin Law"), will merge with and into Holding, a wholly-owned subsidiary
of Associated (the "Merger"); and

         WHEREAS, the Company and its Board of Directors have determined that
the Merger will enhance the ability of the Bank to better serve its existing
depositors and customers in Portage, Wisconsin, and increase the financial
strength of the Bank; and

         WHEREAS, the Board of Directors of the Company believes that the
Merger with Holding will benefit the shareholders and the employees of the
Company and the Subsidiaries; and

         WHEREAS, the respective Boards of Directors of Associated, Holding and
the Company have (i) determined that the Merger and the exchange of newly
issued shares of Associated Common Stock (as defined in Section 1.06) for
shares of the Company's Common Stock (as defined in Section 1.06) pursuant and
subject to the terms and conditions of this Agreement are fair to and in the
best interests of the respective corporations and their shareholders, and (ii)
approved and adopted this Agreement and the transactions contemplated hereby;
and

         WHEREAS, the Board of Directors of the Company has, subject to its
fiduciary duties under applicable law, resolved to recommend approval of the
Merger by the shareholders of the Company; and

         WHEREAS, Associated, Holding and the Company intend to effect a merger
that qualifies for pooling-of-interests accounting treatment and as a tax-free
reorganization under the Internal Revenue Code of 1986, as amended (the
"Code"); and

         WHEREAS, as a condition and inducement to Associated's willingness to
enter into this Agreement, Associated and certain shareholders of the Company
are entering into concurrently with the execution and delivery hereof, a Voting
Agreement dated as of the date hereof (the "Voting Agreement"), pursuant to
which such shareholders shall make certain agreements with respect to the
voting of their shares of Company Common Stock.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Associated, Holding and the Company hereby agree as follows:

                                   ARTICLE I

                                   THE MERGER

         SECTION 1.01.  The Merger.  Upon the terms and subject to the
conditions set forth in this Agreement, and in accordance with Wisconsin Law,
at the Effective Time (as defined in Section 1.02) the Company shall be merged

         SECTION 1.02.  Effective Time.  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 Wisconsin, in such form as

conditions set forth in Article VII, and (b) as promptly as possible within the
sixty (60) day period commencing with the latest of the following dates:

                 (i)      The 30th calendar day after the date of approval of
         the Merger by the Board of Governors of the Federal Reserve System
         (the "Federal Reserve Board");

                 (ii)     Such date as may be prescribed by the Federal Reserve
         Board or any other agency or authority pursuant to applicable law,
         rules or regulations, prior to which consummation of the transaction
         described and referred to herein may not be effected;

                 (iii)    The date of the shareholders' meeting of the Company
         to vote upon the Merger pursuant to Section 6.02; or

                 (iv)     If the transaction contemplated by this Agreement is
         being contested in any legal proceeding and Associated or the Company
         has elected to contest the same, the date that such legal proceeding
         has been brought to a conclusion favorable, in the judgment of
         Associated or the Company, to the consummation of the transaction
         contemplated hereby.

                 The date and time of the filing of the Articles of Merger is
hereinafter referred to as the "Effective Time."  Anything to the contrary
notwithstanding, the Effective Time shall not under any circumstances occur
prior to February 15, 1996.

         SECTION 1.03.  Effect of the Merger.  At the Effective Time, the
effect of the Merger shall be as provided in the applicable provisions of
Wisconsin Law. Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time, except as otherwise provided herein, all the
property, rights, privileges, powers and franchises of Holding and the Company
shall vest in the Surviving Corporation, and all debts, liabilities and duties
of Holding and the Company shall become the debts, liabilities and duties of
the Surviving Corporation.

         SECTION 1.04.  Articles of Incorporation and Bylaws.  At the Effective
Time, the Articles of Incorporation and the Bylaws of Holding, as in effect
immediately prior to the Effective Time, shall be the Articles of Incorporation
and the Bylaws of the Surviving Corporation.

         SECTION 1.05.  Directors and Officers.  The directors of Holding
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

Holding immediately prior to the Effective Time shall be the initial officers
of the Surviving Corporation, in each case until their respective successors

         SECTION 1.06.  Conversion of Securities.  At the Effective Time, by
virtue of the Merger and without any action on the part of Associated, Holding,
the Company, or the holders of any of the following securities:

                 (a)      each Share of common stock, par value $1 per share,
         of the Company (the "Company Common Stock") (all issued and
         outstanding shares of the Company Common Stock being hereinafter
         collectively referred to as the "Shares") issued and outstanding
         immediately prior to the Effective Time (other than any Shares to be
         cancelled pursuant to Section 1.06(b) and other than any Dissenting
         Shares, as defined in Section 1.06(c)) shall be converted, in
         accordance with Section 1.07, into the right to receive 1.0665 shares
         of common stock, par value $.01 per share, of Associated ("Associated
         Common Stock").  As of the Effective Time, all such shares of the
         Company Common Stock shall no longer be outstanding and shall
         automatically be cancelled and retired and shall cease to exist, and
         each certificate previously representing any such Shares shall
         thereafter represent the right to receive a certificate representing
         shares of Associated Common Stock into which such Company Common Stock
         is convertible.  Certificates previously representing shares of
         Company Common Stock shall be exchanged for certificates representing
         whole shares of Associated Common Stock issued in consideration
         therefor upon the surrender of such certificates in accordance with
         the provisions of Section 1.07, without interest.  No fractional
         shares of Associated Common Stock shall be issued, and, in lieu
         thereof, a cash payment shall be made pursuant to Section 1.07 hereof.

                 (b)      each Share held in the treasury of the Company and
         each Share owned by Associated or any direct or indirect wholly-owned
         subsidiary of Associated immediately prior to the Effective Time shall
         be cancelled and extinguished without any conversion thereof and no
         payment shall be made with respect thereto.

                 (c)      each Share of the Company Common Stock which shall be
         issued and outstanding as of the Effective Time and held by a
         shareholder who has validly perfected dissenter's rights in accordance
         with Wisconsin Law, shall not be converted into and shall not become
         Associated Common Stock hereunder (all such shares of the Company
         Common Stock are hereinafter called "Dissenting Shares").  The Company
         shall give Associated prompt notice upon receipt by the Company of any
         written notice from any such shareholder of the Company ("Dissenting
         Shareholder").  The Company agrees that prior to the Effective Time,
         it will not, except with prior written consent of Associated,
         voluntarily make any payment with respect to, or settle or offer to
         settle, any request for withdrawal pursuant to the exercise of
         dissenter's rights.  Each Dissenting Shareholder who becomes entitled,
         pursuant to the provisions of applicable law, to payment for his or
         her shares of the Company Common Stock shall receive payment therefor
         from Associated (but only after the amount thereof shall be agreed
         upon or finally determined pursuant to the provisions of applicable
         law).  If any Dissenting Shareholder shall fail to perfect or shall
         effectively withdraw or lose his or her right to receive the value of
         his or her shares of Associated Common Stock, his or her shares shall
         be thereupon converted into Associated Common Stock in accordance with
         the provisions of Section 1.06(a) and, if applicable, cash under
         Section 1.07(e).

         SECTION 1.07.  Exchange of Certificates.

                 (a)      Exchange Agent  As of the Effective Time, Associated
         shall deposit, or shall cause to be deposited, with Harris Trust &
         Savings Bank (the "Exchange Agent"), and such deposit shall be solely
         for the benefit of the holders of Shares, for exchange in accordance
         with this Article I through the Exchange Agent, certificates
         representing the shares of Associated Common Stock (such certificates
         for shares of Associated Common Stock, and cash in lieu of fractional
         shares (if any), together with any dividends or distributions with
         respect thereto, being hereinafter





                                      A-3

         referred to as the "Exchange Fund") issuable pursuant to Section 1.06 
         in exchange for outstanding Shares.

                 (b)      Exchange Procedures.  As soon as reasonably
         practicable after the Effective Time, the Exchange Agent shall mail or
         personally deliver to each holder of record (or his or her
         attorney-in-fact) of a certificate or certificates which immediately
         prior to the Effective Time represented outstanding Shares (the
         "Certificates"), whose Shares were converted into the right to receive
         shares of Associated Common Stock pursuant to Section 1.06 and cash in
         lieu of fractional shares (if any), (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 Associated may reasonably specify) and (ii)
         instructions for use in effecting the surrender of the Certificates in
         exchange for certificates representing shares of Associated Common
         Stock.  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 a certificate representing that number of whole
         shares of Associated Common Stock which such holder has the right to
         receive in respect of the Certificate surrendered pursuant to the
         provisions of this Article I (after taking into account all Shares
         then held by such holder) and cash in lieu of fractional shares (if
         any), and the Certificate so surrendered shall forthwith be cancelled.
         In the event of a transfer of ownership of Shares which is not
         registered in the transfer records of the Company, a certificate
         representing the proper number of shares of Associated Common Stock
         may be issued to a transferee 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.
         Certificates surrendered for exchange by any affiliate of the Company
         shall not be exchanged for certificates representing shares of
         Associated Common Stock until Associated has received a written
         agreement from such person as provided in Section 4.05 hereof.  Until
         surrendered as contemplated by this Section 1.07, each Certificate
         shall be deemed at any time after the Effective Time to represent only
         the right to receive upon such surrender the certificate representing
         shares of Associated Common Stock and cash in lieu of any fractional
         shares of Associated Common Stock as contemplated by Section 1.07(e).

                 (c)      Distributions with Respect to Unexchanged Shares.  No
         dividends or other distributions declared or made after the Effective
         Time with respect to Associated 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 Associated Common Stock
         represented thereby, and no cash payment in lieu of fractional shares
         shall be paid to any such holder pursuant to Section 1.07(e), 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 Associated Common Stock
         issued in exchange therefor, without interest, (i) promptly, the
         amount of any cash payable with respect to a fractional share of
         Associated Common Stock to which such holder is entitled pursuant to
         Section 1.07(e) 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 Associated 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 Associated Common stock.

                 (d)      No Further Rights in the Shares.  All shares of
         Associated Common Stock issued upon conversion of the Shares in
         accordance with the terms hereof (including any cash paid pursuant to
         Section 1.07(e)) shall be deemed to have been issued in full
         satisfaction of all rights pertaining to such Shares.

                 (e)      No Fractional Shares  No certificates or scrip
         representing fractional shares of Associated Common Stock shall be
         issued upon the surrender for exchange of Certificates, and such
         fractional share interest will not entitle the owner thereof to vote
         or to any rights of a shareholder of Associated.  Each holder of a
         fractional share interest shall be paid an amount in cash equal to the
         product obtained by multiplying such fractional share interest to
         which such holder (after taking into account all fractional share
         interests then held by such holder) would otherwise be entitled by the
         "Order Date Price."  For purposes hereof, the "Order Date Price" shall
         mean the closing price of a share of Associated Common Stock as quoted
         on the NASDAQ National Market on the first business day following the
         date the Federal Reserve Board issues an order approving consummation
         of the Merger.

                 (f)      Termination of Exchange Fund.  Any portion of the
         Exchange Fund which remains undistributed to the shareholders of the
         Company for six months after the Effective Time shall be delivered to
         Associated, upon demand, and any shareholders of the Company who have
         not theretofore complied with this Article I shall thereafter look
         only to Associated for payment of their claim for Associated Common
         Stock, any cash in lieu of fractional shares of Associated Common
         Stock and any dividends or distributions with respect to Associated
         Common Stock.

                 (g)      No Liability.  Neither Associated, Holding or the
         Company shall be liable to any holder of Shares for any such Shares
         (or dividends or distributions with respect thereto) or cash delivered
         to a public official pursuant to any abandoned property, escheat or
         similar law.

                 (h)      Withholding Rights.  Associated shall be entitled to
         deduct and withhold from any cash consideration payable pursuant to
         this Agreement to any holder of Shares such amounts as Associated 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 Associated,
         such withheld amounts shall be treated for all purposes of this
         Agreement as having been paid to the holder of the Shares in respect
         of which such deduction and withholding was made by Associated.

         SECTION 1.08.  Stock Transfer Books.  At the Effective Time, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers of shares of the Company's Common Stock thereafter on
the records of the Company.  From and after the Effective Time, the holders of
certificates evidencing ownership of shares of the Company's 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 Associated for any reason shall be converted into shares of
Associated Common Stock in accordance with this Article I.

         SECTION 1.09.  Anti-Dilution Adjustment.  If, subsequent to the date
hereof and prior to the Effective Time, Associated shall pay a stock dividend
or make a distribution on Associated Common Stock in shares of Associated
Common Stock or any security convertible into Associated Common Stock or shall
combine or subdivide its stock, then in each such case, from and after the
record date for determining the shareholders entitled to receive such dividend
or distribution or the securities resulting from such combination or
subdivision, an appropriate adjustment shall be made to the conversion ratio
set forth in Section 1.06 above, for purposes of determining the number of
shares of Associated Common Stock into which the Company's Common Stock shall
be converted.  For purposes hereof, the payment of a dividend in Associated
Common Stock, or the distribution on Associated Common Stock in securities
convertible into Associated Common Stock, shall be deemed to have effected an
increase in the number of outstanding shares of Associated Common Stock equal
to the number of shares of Associated Common Stock into which such securities
shall be initially convertible without the payment by the holder thereof of any
consideration other than the surrender for cancellation of such convertible
securities.  Notwithstanding the foregoing, this





                                      A-5

Section shall not apply to any stock options issued under option plans of
Associated existing as of the date of this Agreement.


                                   ARTICLE II

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

the Subsidiaries, taken as a whole.  The term "Material Adverse Effect" as used
in this Agreement shall mean any change or effect that is or is reasonably
likely to be materially adverse to a party's business, operations, properties

good standing, in each jurisdiction where the character of their properties
owned, leased or operated by them or the nature of their activities makes such

or in the aggregate, have a Material Adverse Effect on the Company or the
Subsidiaries, taken as a whole.  The Company is registered with the Federal
Reserve Board as a one bank holding company under the Bank Holding Company Act
of 1956, as amended (the "BHCA").  Except for the Subsidiaries, the Company

than, with respect to the Merger, the approval and adoption of this Agreement
by the holders of a majority of the outstanding shares of the Company's Common
Stock in accordance with Wisconsin Law and the Company's Articles of
Incorporation and Bylaws).  This Agreement has been duly and validly executed

obligation of the Company enforceable in accordance with its terms.

         SECTION 2.05.  No Conflict; Required Filings and Consents.

                 (a)      To the best knowledge of the Company, after inquiry
         of its executive officers, the execution and delivery of this
         Agreement by the Company does not, and the performance of this
         Agreement by the Company shall not, (i) conflict with or violate the
         Articles of Incorporation or Bylaws of the Company or the
         Subsidiaries, (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 the
         Company or the Subsidiaries, or by which their respective





                                      A-7
<PAGE>   59


         properties are 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 the Company or the Subsidiaries pursuant to any note, bond,
         mortgage, indenture, contract, agreement, lease, license, permit,
         franchise or other instrument or obligation to which the Company or
         any Subsidiary is a party or by which the Company or any Subsidiary or
         its or any of their respective properties are bound or affected,
         except for any such breaches, defaults or other occurrences that would
         not, individually or in the aggregate, have a Material Adverse Effect
         on the Company or the Subsidiaries, taken as a whole.  The Board of
         Directors of the Company has taken all actions necessary under
         Wisconsin Law, including approving the transactions contemplated
         herein, to insure that none of the restrictions set forth in Wisconsin
         Law do or will apply to the transactions contemplated herein.

                 (b)      To the best knowledge of the Company, after inquiry
         of its executive officers, the execution and delivery of this
         Agreement by the Company does not, and 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 of 1933, as
         amended (the "Securities Act"), and the Securities Exchange of 1934,
         as amended (the "Exchange Act"), state securities or blue sky laws
         ("Blue Sky Laws"), BHCA, the banking laws and regulations of the State
         of Wisconsin (the "WBL"), and the filing and recordation of
         appropriate merger or other documents as required by Wisconsin 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 Subsidiaries, taken as a whole.

         SECTION 2.06.  Compliance; Permits.  To the best knowledge of the
Company after inquiry of its executive officers, neither the Company nor any
Subsidiary is in conflict with, or in default or violation of, (a) any law
applicable to the Company or any Subsidiary or by which any of their respective
properties are bound or affected, or (b) any note, bond, mortgage, indenture,
contract, agreement, lease, license, permit, franchise or other instrument or
obligation to which the Company or any Subsidiary is a party or by which the
Company or any Subsidiary or any of their respective properties are 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 the
Company or the Subsidiaries, taken as a whole.

         SECTION 2.07.  Banking Reports and Financial Statements.

                 (a)      The Company and the Subsidiaries have timely filed
         all forms, reports and documents required to be filed with the Federal
         Reserve Board, the Wisconsin Commissioner and any other applicable
         federal or state securities or banking authorities (all such reports
         and statements are collectively referred to as the "Company Reports").
         The Company Reports, including all Company Reports filed after the
         date of this Agreement, (i) were or will be prepared 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 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 of the
         Company (including, in each case, any related notes thereto) delivered
         to Associated whether or not contained in the Company Reports (the
         "Financial Statements"), including, but not limited to, any Company
         Reports filed since the date of this Agreement and prior to or at the
         Effective Time, have been prepared in





                                      A-8

         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 the Company and the 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 as and to the extent set forth on the
         consolidated balance sheet of the Company and the Subsidiaries as of
         December 31, 1994, including all notes thereto (the "Company Balance
         Sheet"), neither the Company nor any of the Subsidiaries has any
         liabilities or obligations of any nature (whether accrued, absolute,
         contingent or otherwise) that would be required to be reflected on a
         balance sheet, or in the notes thereto, prepared in accordance with
         generally accepted accounting principles, except (i) for liabilities
         or obligations incurred in the ordinary course of business since
         December 31, 1994, that would not, individually or in the aggregate
         have a Material Adverse Effect on the Company or the Subsidiaries,
         taken as a whole, or (ii) as otherwise reflected in the reports
         referred to in Section 2.07(a) hereof.

         SECTION 2.08.  Absence of Certain Changes or Events.  Except as
disclosed in the Financial Statements since December 31, 1994, to the date of
this Agreement, the Company and the Subsidiaries have conducted their
businesses only in the ordinary course and in a manner consistent with past
practice and, since December 31, 1994, there has not been (a) any change in the
financial condition, results of operations or business of the Company or the
Subsidiaries having a Material Adverse Effect on the Company or the
Subsidiaries, taken as a whole, (b) any damage, destruction or loss (whether or
not covered by insurance) with respect to any assets of the Company or the
Subsidiaries having a Material Adverse Effect on the Company or the
Subsidiaries, taken as a whole, (c) any change by the Company or the
Subsidiaries in their accounting methods, principles or practices, except for
compliance with applicable new requirements of the Financial Accounting
Standards Board, (d) any revaluation by the Company or the Subsidiaries of any
of their material assets in any material respect, (e) any entry by the Company
or any Subsidiary into any commitment or transactions material to the Company
or the Subsidiaries, taken as a whole, (f) any declaration, setting aside or
payment of any dividends or distributions in respect of shares of the Company's
Common Stock or any redemption, purchase or other acquisition of any of its
securities or any of the securities of any Subsidiary, or (g) any increase in
or establishment of any bonus, insurance, severance, deferred compensation,
pension, retirement, profit sharing, stock option (including, without
limitation, the granting of stock options, stock appreciation rights,

employee benefit plan, or any other increase in compensation payable or to
become payable to any officers or key employees of the Company or any of the
Subsidiaries.

         SECTION 2.09.  Absence of Litigation.  Except as disclosed in the
Company Reports filed prior to the date of this Agreement:  (a) neither the
Company nor any Subsidiary is subject to any continuing order of, or written
agreement or memorandum of understanding with, or continuing material

governmental entity or arbitrator, including, without limitation,
cease-and-desist or other orders of any bank regulatory authority, (b) there is
no claim of any kind, action, suit, litigation, proceeding, arbitration,

have, and cannot reasonably be expected to have, a Material Adverse Effect on
the Company or the Subsidiaries taken as a whole, and (c) there are no uncured
material violations, or violations with respect to which material refunds or
restitutions may be required, cited in any compliance report to the Company or
any Subsidiary as a result of the examination by any regulatory authority.  The

$120,000 payment by the Bank and a $135,000 reimbursement to the Bank from
Cincinnati Insurance, the Bank's insurance carrier, for the claim and related
costs.

         SECTION 2.10.   Employee Benefit Plans.

                 (a)      The Company Disclosure Schedule at Section 2.10 lists
         all "employee pension benefit plans," as such term is defined in
         section 3(2) of the Employee Retirement Income Security Act of 1974
         ("ERISA") without regard to any exemptions from any requirements
         thereunder issued by the United States Department of Labor in
         regulations or otherwise, maintained, sponsored or contributed to by
         the Company or any Subsidiary (the "Pension Plans").  The term
         "Pension Plan" shall also include any terminated "employee pension
         benefit plan" previously maintained, sponsored or contributed to by
         the Company or any Subsidiary which, as of the Effective Time, has not
         distributed all of its assets in full satisfaction of accrued benefits
         and/or obligations.

                 (b)      The Company Disclosure Schedule at Section 2.10 lists
         all "employee welfare benefit plans," as defined in ERISA section 3(1)
         without regard to any exemptions from any requirements thereunder
         issued by the United States Department of Labor in regulations or
         otherwise, maintained, sponsored or contributed to by the Company or
         any Subsidiary (the "Welfare Plans").  The term "Welfare Plans" shall
         also include any terminated employee welfare benefit plan previously
         maintained, sponsored or contributed to by the Company or any
         Subsidiary which, as of the Effective Time, has not distributed all of
         its assets and/or satisfied all of its obligations.

                 (c)      The Company has made available to Associated true and
         complete copies of the documents governing each of the Pension Plans
         and Welfare Plans as in effect at the Effective Time.

                 (d)      The Company Disclosure Schedule at Section 2.10 lists
         all plans or programs to provide fringe benefits to the Company's and
         Subsidiaries' employees (other than Pension Plans and Welfare Plans)
         including, but not limited to, vacation, sick leave, disability,
         medical, hospitalization, life insurance and other insurance plans or
         related benefits (the "Fringe Benefit Plans").

                 (e)      The Company has made available to Associated true and
         complete copies of the documents governing each Fringe Benefit Plan.

                 (f)      The Company has no direct or indirect, formal or
         informal, plan, fund or program to change any Pension Plan, Welfare
         Plan or Fringe Benefit Plan that would affect any of the Company's or
         any Subsidiary's employees.  Neither the Company nor any Subsidiary
         has made a material modification, within the meaning of ERISA section
         102 and the regulations thereunder, to any existing Pension Plan,
         Welfare Plan or Fringe Benefit Plan which is not set forth in the
         Pension Plan, Welfare Plan or Fringe Benefit Plan documents provided
         to Associated.

                 (g)      For purposes of this Section 2.10, "Company" shall
         include the Company, the Subsidiaries and all members of any
         controlled group of corporations (within the meaning of Code section
         414(b), relevant Treasury Regulations and Pension Benefit Guaranty
         Corporation regulations issued pursuant to ERISA section 4001), any
         group of trades or businesses under common control (within the meaning
         of Code section 414(c), relevant Treasury Regulations and Pension
         Benefit Guaranty Corporation regulations issued pursuant to ERISA
         section 4001) and any affiliated service group (within the meaning of
         Code section 414(m) and relevant Treasury Regulations and proposed
         Treasury Regulations) of which the Company or any Subsidiary is a
         member.

<PAGE>   62


                 (h)      Neither the Company nor any Subsidiary has ever been
         obligated to contribute to any multi-employer plan within the meaning
         of ERISA section 3(37).

                 (i)      To the Company's knowledge, the Pension Plans,
         Welfare Plans and Fringe Benefit Plans and the trusts and other
         funding vehicles related to the Pension Plans, Welfare Plans and
         Fringe Benefit Plans have been administered in all respects in
         compliance with the applicable requirements of ERISA, the Code, the
         plan documents and all other applicable rules, regulations and laws.
         The Pension Plans, Welfare Plans and Fringe Benefit Plans and the
         trusts or other funding vehicles related to the Pension Plans, Welfare
         Plans and Fringe Benefit Plans meet all applicable requirements, in
         form and in operation, for favorable tax treatment under the Code.
         All required contributions pursuant to the Pension Plans, Welfare
         Plans and Fringe Benefit Plans for all periods prior to the Effective
         Time have been made or will be made prior to the Effective Time.
         There are no pending or, to the Company's knowledge, threatened
         claims, lawsuits or arbitrations which have been asserted or
         instituted against the Pension Plans, Welfare Plans or Fringe Benefit
         Plans or any fiduciaries thereof with respect to their duties to the
         Pension Plans, Welfare Plans or Fringe Benefit Plans or the assets of
         any of the trusts under any Pension Plans, Welfare Plans or Fringe
         Benefit Plans.  No representations or communications with respect to
         participation, eligibility for benefits, vesting, benefit accrual or
         coverage under the Pension Plans, Welfare Plans or Fringe Benefit
         Plans have been made to the Company's or Subsidiaries' employees other
         than those which are in accordance with the terms of such Pension
         Plans, Welfare Plans or Fringe Benefit Plans in effect immediately
         prior to the Effective Time.

                 (j)      With respect to any Welfare Plan which is a "group
         health plan" as defined in Code section 4980B, the Company or
         Subsidiary in question has complied with the continuation coverage
         requirements of Code section 4980B for any periods prior to the
         Effective Time.

                 (k)      The Company has furnished to Associated copies of all
         documents relating to the Pension Plans, Welfare Plans or Fringe
         Benefit Plans, including, but not limited to, the following:  any
         service provider agreements, any investment management agreements,
         fiduciary insurance policies, fidelity bonds, rules, regulations or
         policies of the trustees or any committee thereunder, all of which are
         true and complete.

                 (l)      Since December 31, 1974, no fiduciary of the Pension
         Plans or Welfare Plans has engaged in any "prohibited transaction" (as
         defined in ERISA section 406 or Code section 4975) nor has any
         fiduciary breached any fiduciary responsibility, as described in Part
         4 of Title I of ERISA with respect to such Pension Plans or Welfare
         Plans.

                 (m)      The Company has no knowledge of the occurrence of any
         event with respect to any Pension Plan which could result in a
         liability of the Company, any Subsidiary or any member of the
         Company's controlled group to the Pension Benefit Guaranty Corporation
         ("PBGC"), other than the timely payment of premiums pursuant to
         section 4007 of ERISA.  All required PBGC premiums have been paid for
         the periods through the Effective Time.

                 (n)      No Welfare Plan or Fringe Benefit Plan provides any
         form of post-retirement health benefits to retired employees of the
         Company or any Subsidiary, other than benefits required to be provided
         pursuant to Code section 4980B.

         SECTION 2.11.  Employment Contracts; Material Contracts.  Except as
set forth in the Company Disclosure Schedule at Section 2.11, neither the
Company nor any Subsidiary is a party to or bound by (a) any employment or
consulting contract that is not terminable without penalty by the Company or
such Subsidiary on 60 days' or less notice, (b) any contract or commitment for
capital expenditures in excess of





                                      A-11
<PAGE>   63


$10,000.00 for any one (1) project, or (c) contracts or commitments for the
purchase of materials or supplies or for the performance of services over a
period of more than 60 days from the date of this Agreement.

         SECTION 2.12.  Registration Statement; Proxy Statement.  None of the
information supplied or to be supplied by the Company for inclusion in (a) the
Registration Statement (as defined in Section 6.01), (b) the Proxy Statement/
Prospectus (as defined in Section 6.01), or (c) any other document to be filed
with the Securities and Exchange Commission (the "SEC") or other regulatory
authority in connection with the transactions contemplated hereby, at the
respective times such documents are filed and, in the case of the Registration
Statement, when it becomes effective and at the Effective Time, and with
respect to the Proxy Statement/Prospectus, when mailed, shall be false or
misleading with respect to any material fact, or omit to state any material
fact necessary in order to make the statements therein not misleading.  In the
case of the Proxy Statement/Prospectus or any amendment thereof or supplement
thereto, none of such information at the time of the Company's shareholders
meeting (pursuant to Section 6.02) (the "Meeting") shall be false or misleading
with respect to any material fact or omit to state any material fact necessary
to correct any statement in any earlier communication with respect to the
solicitation of any proxy for the Meeting.

         SECTION 2.13.  Title to Property.  The Company Disclosure Schedule at
Section 2.13 correctly identifies all real property owned and leased by the
Company and the Subsidiaries.  The Company and each of the Subsidiaries has
good and defensible title to all of their properties and assets, real and
personal, tangible and intangible 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 to 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
the Company or the Subsidiaries, taken as a whole; and all leases pursuant to
which the Company or any Subsidiary leases from others real or personal
property including, without limitation, leases for branch offices 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 (or event which with notice or lapse of time, or both, would
constitute a material default and in respect of which the Company or any
Subsidiary has not taken adequate steps to prevent such a default from
occurring).  The Company's and each Subsidiary's buildings and equipment in
regular use have been reasonably maintained and are in good and serviceable
condition, reasonable wear and tear excepted.  None of the buildings,
structures or appurtenances owned or leased by the Company or any Subsidiary
for their operation or maintenance as now operated or maintained, contravenes
any zoning ordinances or other administrative regulations (whether or not
permitted because of prior non-conforming use) or violates any restrictive
covenant or any provision of law, the effect of which would materially
interfere with or prevent the continued use of such properties for the purposes
for which they are now being used or would materially and adversely affect the
value thereof.

         SECTION 2.14.  Compliance with Environmental Laws.

                 (a)      The term "Company's Property" shall mean any real
         property and improvements currently owned, leased, used, operated or
         occupied by the Company or any Subsidiary, including properties
         acquired by foreclosure, properties which the Bank has a present right
         to acquire upon foreclosure and which are owned by customers of the
         Bank who have received written notification of default, or properties
         held or operated in a fiduciary or managerial capacity;

                 (b)      The term "Environmental Claims" shall mean any and
         all administrative, regulatory or judicial actions, suits, demands,
         demand letters, claims, liens, notices of noncompliance or violation,
         investigations or proceedings relating in any way to any Environmental
         Law or Environmental Permit;





                                      A-12
<PAGE>   64


                 (c)      The term "Environmental Laws" shall mean all federal,
         state and local laws including statutes, regulations and other
         governmental restrictions and requirements relating to the discharge
         of air pollutants, water pollutants or process wastewater or the
         disposal of solid or hazardous waste or otherwise relating to the
         environment or hazardous substances or employee health and safety.

                 (d)      The term "Environmental Permits" shall mean all
         permits, approvals, identification numbers, licenses and other
         authorizations required under any applicable Environmental Law.

                 (e)      The term "Hazardous Substances" shall mean all
         hazardous and toxic substances, wastes and materials; any pollutants
         or contaminants (including, without limitation, petroleum products,
         asbestos and raw materials which include hazardous constituents); and
         any other similar substances or materials which are regulated under
         Environmental Laws.

                 (f)      The Environmental Permits (if any) are in full force
         and effect and, to the Company's knowledge, constitute all permits,
         licenses, approvals and consents relating to Environmental Laws or
         Hazardous Substances required for the conduct of the Company's and
         Subsidiaries' businesses and the use of the Company's Property (as
         presently conducted and used) in compliance with Environmental Laws.

                 (g)      The Company and the Subsidiaries have filed all
         reports, returns and other filings required to be filed with respect
         to the Company's Property under Environmental Laws and the
         Environmental Permits except where the failure to do so would not have
         a material adverse effect on the Company's or Subsidiaries' businesses
         or financial condition, taken as a whole.  The Company and/or the
         Subsidiaries have made no environmental filings after January 1, 1995.

                 (h)      To the Company's knowledge, the business of the
         Company and the Subsidiaries and the Company's Property have been and
         are being operated by the Company in accordance with all Environmental
         Laws and Environmental Permits.  Neither the Company nor any of the
         Subsidiaries has received any written notice nor does the Company or
         any of the Subsidiaries have knowledge that the Company's Property is
         not in material compliance with all Environmental Laws and
         Environmental Permits and no proceeding for the suspension, revocation
         or cancellation of any Environmental Permit is pending or, to the
         Company's knowledge, threatened.

                 (i)      There are no actions pending, or to the Company's
         knowledge, threatened against the Company or any of the Subsidiaries
         (naming the Company or any Subsidiary), which in any case assert or
         allege (i) the Company or any Subsidiary (naming the Company or any
         Subsidiary) violated any Environmental Law or Environmental Permit or
         are in default with respect to any Environmental Permit or any order,
         writ, judgment, variance, award or decree of any government authority;
         (ii) the Company or any of the Subsidiaries is required to clean up or
         take remedial or other response action due to the disposal, discharge
         or other release of any Hazardous Substance on the Company's Property
         or elsewhere; or (iii) the Company or any of the Subsidiaries is
         required to contribute to the cost of any past, present or future
         cleanup or remedial or other response action which arises out of or is
         related to the disposal, discharge or other release or any Hazardous
         Substance by the Company, the Subsidiaries or others.  The Company,
         the Subsidiaries and the Company's Property are not subject to any
         judgment, stipulation, order, decree or agreement arising under
         Environmental Laws.

                 (j)      With respect to the period during which the Company
         or any of the Subsidiaries occupied the Company's Property (i) no
         Hazardous Substances have been treated, recycled or disposed of by the
         Company or any of the Subsidiaries (intentionally or unintentionally)
         on, under





                                      A-13
<PAGE>   65


         or at the Company's Property; (ii) there has been no release or
         threatened release by the Company or any of the Subsidiaries of any
         Hazardous Substance from the Company's Property; (iii) to the
         Company's knowledge, there have been no activities on the Company's
         Property which would subject Associated, Holding, the Subsidiaries, or
         any subsequent occupier of the Company's Property to damages,
         penalties, injunctive relief or cleanup costs under any Environmental
         Laws or common law theory of liability.

         SECTION 2.15.  Absence of Agreements.  Neither the Company nor any
Subsidiary is a party to any written 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 the
Company or any 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, the Company or any Subsidiary may carry on its business), or in any
manner relates to its capital adequacy, its credit policies or its management
nor has the Company or any Subsidiary 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.

         SECTION 2.16.  Taxes.  The Company and the Subsidiaries have timely
filed all Tax Returns (as defined below) required to be filed by them, and the
Company and the Subsidiaries have timely paid and discharged all Taxes (as
defined below) due in connection with or with respect to the filing of such Tax
Returns and have timely paid all other Taxes as are due, except such as are
being contested in good faith by appropriate proceedings and with respect to
which the Company is maintaining reserves adequate for their payment.  To the
best knowledge of the Company, 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, including, without limitation, (a) income,
franchise, profits, gross receipts, estimated, ad valorem, value added, sales,
use, service, real or personal property, capital stock, license, payroll,
withholding, disability, employment, social security, workers compensation,
unemployment compensation, utility, severance, production, excise, stamp,
occupation, premiums, windfall profits, transfer and gains taxes, (b) customs
duties, imposts, charges, levies or other similar assessments of any kind, and
(c) interest, penalties and additions to tax imposed with respect thereto, and
"Tax Returns" shall mean returns, reports, and information statements with
respect to Taxes required to be filed with the United States Internal Revenue
Service (the "IRS") or any other governmental entity or taxing authority or
agency, domestic or foreign, including, without limitation, consolidated,
combined and unitary tax returns.  Neither the IRS nor any other governmental
entity or taxing authority or agency is now asserting, either through audits,
administrative proceedings, court proceedings or otherwise, or, to the best of
the Company's knowledge, threatening to assert against the Company or any
Subsidiary any deficiency or claim for additional Taxes.  Neither the Company
nor any Subsidiary has granted any waiver of any statute of limitations with
respect to, or any extension of a period for the assessment of, any Tax.  There
are no tax liens on any assets of the Company or any Subsidiary.  Neither the
Company nor any Subsidiary has received a ruling or entered into an agreement
with the IRS or any other governmental entity or taxing authority or agency
that would have a Material Adverse Effect on the Company or the Subsidiaries,
taken as a whole, after the Effective Time.  The accruals and reserves for
taxes reflected in the Company's Balance Sheet are adequate to cover all Taxes
accruable by the Company and the Subsidiaries on a consolidated basis through
the date thereof (including Taxes being contested) in accordance with generally
accepted accounting principles.  Except as may be set forth in the Company
Disclosure Schedule at Section 2.16, no agreements relating to allocating or
sharing of Taxes exist between the Company and the Subsidiaries.

         SECTION 2.17.  Insurance.  Complete and correct copies of all material
policies of fire, product or other liability, workers' compensation and other
similar forms of insurance owned or held by the Company and the Subsidiaries
have been delivered to Associated.  Subject to expirations and renewals of
insurance policies in the ordinary course of business, all such policies are in
full force and effect, all premiums with respect thereto covering all periods
up to and including the date as of which this representation is being made have
been paid (other than retrospective premiums which may be payable with respect
to workers' compensation insurance policies), and no notice of cancellation or
termination has been received with respect to any such policy.  Such policies
are and shall remain valid, outstanding and enforceable policies, and will not
be terminated prior to the Effective Time.  To the best knowledge of the
Company, the insurance policies to which the Company or the Subsidiaries are
parties are sufficient for compliance with all material requirements of law and
all material agreements to which the Company or the Subsidiaries are parties
and will be maintained by the Company and the Subsidiaries until the Effective
Time.  Neither the Company nor any Subsidiary has been refused any insurance
with respect to any material assets or operations, nor has coverage been
limited in any respect material to their operations by any insurance carrier to
which they have applied for any such insurance or with which they have carried
insurance during the last five (5) years.

         SECTION 2.18.  Absence of Adverse Agreements.  Neither the Company nor
any Subsidiary is a party to any agreement or instrument or any judgment, order
or decree or any rule or regulation of any court or other governmental agency
or authority which materially and adversely affects or in the future may have a
Material Adverse Effect on the financial condition, results or operations,
assets, business or prospects of the Company or the Subsidiaries, taken as a
whole.

         SECTION 2.19.  Internal Controls and Records.  The Company and each
Subsidiary maintain books of account which accurately and validly reflect, in
all material respects, all loans, mortgages, collateral and other business
transactions and maintain accounting controls sufficient to ensure that all
such transactions are (a) in all material respects, executed in accordance with
its management's general or specific authorization, and (b) recorded in
conformity with generally accepted accounting principles.  There is no
amendment to any ending agreement, collateral document or security which is not
fully reflected in the books and records of the Company or the Subsidiaries.

         SECTION 2.20.  Loans.  Except as disclosed in the Company Disclosure
Schedule at Section 2.20, (a) the Bank is not a party to any written or oral
loan agreement, note or borrowing arrangement which has been classified as
"substandard," "doubtful," "loss," "other loans especially mentioned" or any
comparable classifications by the Company or the Subsidiaries or banking
regulators; (b) neither the Company nor any Subsidiary is a party to any
written or oral loan agreement, note, or borrowing arrangement, including any
loan guaranty, with any director or executive officer of the Company or any
Subsidiary, or any person, corporation or enterprise controlling, controlled by
or under common control with any of the foregoing; or (c) neither the Company
nor any Subsidiary is a party to any written or oral loan agreement, note or
borrowing arrangement in violation of any law, regulation or rule of any

         SECTION 2.22.  Brokers.  No broker, finder or investment banker is

made by or on behalf of the Company or the Subsidiaries.

         SECTION 2.23.  Accounting and Tax Matters.

                 (a)      To the best knowledge of the Company, neither the
         Company nor any of its affiliates has through the date of this
         Agreement taken or agreed to take any action that would prevent
         Associated from accounting for the business combinations to be
         effected by the Merger as a pooling-of-interests or would prevent the
         Merger from qualifying as a reorganization under Section 368(a)(1)(A)
         of the Code.

                 (b)      To the best knowledge of the Company, there is no
         plan or intention on the part of shareholders of the Company who will
         receive Associated Common Stock to sell or otherwise dispose of an
         amount of Associated Common Stock to be received in the Merger which
         would reduce their ownership of Associated Common Stock to a number of
         shares having in the aggregate a value at the time of the Merger of
         less than fifty percent (50%) of the total value of the Company's
         Common Stock outstanding immediately prior to the Merger.

         SECTION 2.24.  Full Disclosure.  No statement contained in any
document, certificate, or other writing furnished or to be furnished by or at
the direction of the Company to Associated in, or pursuant to the provisions
of, this Agreement contains or shall contain any untrue statement of a material
fact or omits or shall omit to state any material fact necessary, in light of
the circumstances under which it was made, in order to make the statements
herein or therein not misleading.

         SECTION 2.25.  Vote Required.  The affirmative vote of a majority of
the votes that holders of the outstanding shares of the Company's Common Stock
are entitled to cast is the only vote of the holders of any class or series of
the Company's capital stock necessary to approve the Merger.


                                  ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF ASSOCIATED

         Except as set forth in the Disclosure Schedule attached hereto (the
"Associated Disclosure Schedule"), Associated hereby represents and warrants to
the Company that:

         SECTION 3.01.  Organization and Qualification.  Associated and Holding
are bank holding companies duly organized and validly existing under the laws
of the State of Wisconsin.  Associated and Holding are registered with the
Federal Reserve Board as bank holding companies under the BHCA.  Associated and
Holding have the requisite corporate power and authority and are in possession
of all franchises, grants, authorizations, licenses, permits, easements,
consents, certificates, approvals and orders (the "Associated Approvals")
necessary to own, lease and operate their properties and to carry on their
businesses as they are now being conducted, including appropriate
authorizations from the Federal Reserve Board, except where the failure to be
so organized and existing or to have such power, authority and Associated
Approvals would not, individually or in the aggregate, have a Material Adverse
Effect on Associated or Holding, taken as a whole.  Associated has not received
any notice of proceedings relating to the revocation or modification of any
such Associated Approvals.  Associated and Holding are duly qualified or
licensed as foreign corporations to do business, and are in good standing, in
each jurisdiction where the character of properties owned, leased or operated
by them or the nature of their activities makes such qualification or licensing
necessary, except for such failures to be so duly qualified or licensed and in





                                      A-16
<PAGE>   68


good standing that would not, either individually or in the aggregate, have a
Material Adverse Effect on Associated or Holding taken as a whole.

         SECTION 3.02.  Articles of Incorporation and Bylaws.  Associated and
Holding have heretofore furnished to the Company a complete and correct copy of
their respective Articles of Incorporation and the Bylaws, as amended or
restated.  Such Articles of Incorporation and Bylaws are in full force and
effect.  Associated and Holding are not in violation of any of the provisions
of their Articles of Incorporation or Bylaws.

         SECTION 3.03.  Capitalization.  The outstanding capital stock of
Associated is, and the shares of Associated Common Stock to be issued pursuant
to the Merger, when so issued, will be, duly authorized, validly issued, fully
paid and non-assessable (except as provided in section 180.0622(2)(b) of
Wisconsin Business Corporation Law) and have not, and will not have, been
issued in violation of the preemptive rights of any person.

         SECTION 3.04.  Authority.  Associated and Holding have the requisite
corporate power and authority to execute and deliver this Agreement and to
perform their obligations hereunder and to consummate the transactions
contemplated hereby.  The execution and delivery of this Agreement by
Associated and Holding and the consummation by Associated and Holding of the
transactions contemplated hereby have been duly and validly authorized by all
necessary corporate action on the part of Associated and Holding and no other
corporate proceedings on the part of Associated or Holding 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
Associated and Holding and, assuming the due authorization, execution and
delivery by the Company, constitutes the legal, valid and binding obligation of
Associated and Holding.

         SECTION 3.05.  No Conflict; Required Filings and Consents.

                 (a)      To the best knowledge of Associated, the execution
         and delivery of this Agreement by Associated and Holding does not, and
         the performance of this Agreement by Associated and Holding shall not,
         (i) conflict with or violate the Articles of Incorporation or Bylaws
         of Associated or Holding, (ii) conflict with or violate any laws
         applicable to Associated or Holding or by which their properties are
         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
         Associated or Holding pursuant to any note, bond, mortgage, indenture,
         contract, agreement, lease, license, permit, franchise or other
         instrument or obligation to which Associated or Holding is a party or
         by which Associated, Holding or their properties are bound or
         affected, except for any such breaches, defaults or other occurrences
         that would not, individually or in the aggregate, have a Material
         Adverse Effect on Associated or Holding, taken as a whole.

                 (b)      To the best knowledge of Associated, the execution
         and delivery of this Agreement by Associated and Holding do not, and
         the performance of this Agreement by Associated and Holding 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, the
         WBL, and the filing and recordation of appropriate merger or other
         documents as required by Wisconsin 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 Associated and Holding from
         performing their





                                      A-17
<PAGE>   69


         obligations under this Agreement, and would not have a Material
         Adverse Effect on Associated or Holding, taken as a whole.

         SECTION 3.06.  Compliance; Permits.  To the best knowledge of
Associated, neither Associated nor Holding is in conflict with, or in default
or violation of (a) any Law applicable to Associated or Holding or by which
their property is bound or affected, or (b) any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which Associated or Holding is a party or by which
Associated or Holding or any of their properties are 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 Associated or Holding,
taken as a whole.

         SECTION 3.07.  Securities Reports; Financial Statements.

                 (a)      As of the date of this Agreement, Associated has
         delivered to the Company in the form filed with the SEC (x)(i) its
         Annual Reports on Form 10-K for the fiscal years ended December 31,
         1991, 1992, 1993, and 1994, respectively, (ii) its Quarterly Reports
         on Form 10-Q for the periods ended March 31, 1995, and June 30, 1995,
         (iii) all definitive proxy statements relating to Associated's
         meetings of shareholders (whether annual or special) held since
         December 31, 1990, (iv) all Reports on Form 8-K filed by Associated
         with the SEC since December 31, 1990, (v) all other reports or
         registration statements (other than Reports on Form 10-Q not referred
         to in clause (ii) above and registration statements on Form S-8 filed
         by Associated with the SEC since December 31, 1990) and (vi) all
         amendments and supplements to all such reports and registration
         statements filed by Associated with the SEC since December 31, 1990
         (collectively, the "Associated SEC Reports").  The Associated SEC
         Reports, including all Associated SEC Reports filed after the date of
         this Agreement, (y)(i) were or will be prepared 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 material fact or omit to state a 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.

                 (b)      Each of the consolidated financial statements
         (including, in each case, any related notes thereto) contained in the
         Associated SEC Reports, including any Associated SEC 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 Associated
         and its 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 as and to the extent set forth on the
         consolidated balance sheet of Associated and its subsidiaries as of
         December 31, 1994, including all notes thereto (the "Associated
         Balance Sheet"), neither Associated nor its subsidiaries have any
         liabilities or obligations of any nature (whether accrued, absolute,
         contingent or otherwise) that would be required to be reflected on a
         balance sheet, or in the notes thereto, prepared in accordance with
         generally accepted accounting principles, except (i) for liabilities
         or obligations incurred in the ordinary course of business since
         December 31, 1994, that would not, individually or in the aggregate,
         have a Material Adverse Effect on Associated or its subsidiaries,
         taken as a whole, or (ii) as otherwise reflected in the reports
         referred to in clause (x)(ii) of Section 3.07(a) hereof.

         SECTION 3.08.  Absence of Certain Changes or Events.  Except as
disclosed in the Associated SEC Reports filed prior to the date of this
Agreement, since December 31, 1994, to the date of this Agreement, Associated
and its subsidiaries have conducted their businesses only in the ordinary
course and in a manner consistent with past practice and, since December 31,
1994, there has not been (a) any change in the financial condition, results of
operations or business of Associated or its subsidiaries having a Material
Adverse Effect on Associated or its subsidiaries, taken as a whole, (b) any
damage, destruction or loss (whether or not covered by insurance) with respect
to any assets of Associated or its subsidiaries having a Material Adverse
Effect on Associated or its subsidiaries, taken as a whole, (c) any change by
Associated in its accounting methods, principles or practices, (d) any
revaluation by Associated of any of its material assets in any material
respect, or (e) to the date of this Agreement, any entry by Associated or any
of its subsidiaries into any commitment or transactions material to Associated
or its subsidiaries, taken as a whole.

         SECTION 3.09.  Absence of Litigation.  Except as disclosed in the
Associated Disclosure Schedule at Section 3.09 and in the Associated SEC
Reports filed prior to the date of this Agreement, there is no claim, action,
suit, litigation, proceeding, arbitration, investigation, or controversy of any
kind affecting Associated or any of Associated's subsidiaries pending or, to
the knowledge of Associated, threatened, except for matters which individually
seek damages not in excess of $100,000 and which otherwise will not have, and
cannot reasonably be expected to have, a Material Adverse Effect on Associated
or its subsidiaries taken as a whole, and there are no uncured material
violations, or violations with respect to which material refunds or
restitutions may be required, cited in any compliance report to Associated or
any of Associated's subsidiaries as a result of an examination by any bank
regulatory authority.

         SECTION 3.10.  Registration Statement; Proxy Statement.  None of the
information supplied or to be supplied by Associated for inclusion in (a) the
Registration Statement (as defined in Section 6.01) (b) the Proxy Statement/
Prospectus (as defined in Section 6.01), or (c) any other document to be filed
with the SEC or other regulatory authority in connection with the transactions
contemplated hereby, at the respective time such documents are filed and, in
the case of the Registration Statement, when it becomes effective and at the
Effective Time, and with respect to the Proxy Statement/Prospectus, when
mailed, shall be false or misleading with respect to any material fact, or omit
to state any material fact necessary in order to make the statements therein
not misleading.  In the case of the Proxy Statement/Prospectus or any amendment
thereof or supplement thereto, none of such information at the time of the
Meeting (as provided for in Section 6.02) shall be false or misleading with
respect to any material fact, or omit to state any material fact necessary to
correct any statement in any earlier communication with respect to the
solicitation of any proxy for the Meeting.  All documents filed with the SEC or
other regulatory authority by Associated in connection with the Merger shall
comply as to form in all material respects with the provisions of applicable
law.

         SECTION 3.11.  Absence of Agreements.  Neither Associated nor Holding
is a party to any written 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 Associated or Holding
to compete in any line of business or with any person or which involve any
restriction of the geographical area in which, or any method by which,
Associated or Holding 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 for those the
existence of which has been disclosed to the Company prior to the date of this
Agreement, nor has Associated or Holding 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 may be disclosed by
Associated in the Associated Disclosure Schedule at Section 3.11.

         SECTION 3.12.  Taxes.  Associated and its subsidiaries have timely
filed all Tax Returns required to be filed by them, and Associated and its
subsidiaries have timely paid and discharged all Taxes due in connection with
or with respect to the filing of such Tax Returns and have timely paid all
other Taxes as are due, except such as are being contested in good faith by
appropriate proceedings and with respect to which Associated is maintaining
reserves adequate for their payment.  To the best knowledge of Associated, 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
Section 3.12, references to Associated and its subsidiaries include former
subsidiaries of Associated for the periods during which any such corporations
were owned, directly or indirectly, by Associated.  Neither the IRS nor any
other governmental entity or taxing authority or agency is now asserting,
either through audits or administrative proceedings, court proceedings or
otherwise, or, to the best of Associated's knowledge, threatening to assert
against Associated or any of its subsidiaries any deficiency or claim for
additional Taxes.  Neither Associated nor any of its 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.  There are no tax liens on any assets of
Associated or any of its subsidiaries.  Neither Associated nor any of its
subsidiaries has received a ruling or entered into an agreement with the IRS or
any other governmental entity or taxing authority or agency that would have a
Material Adverse Effect on Associated or its subsidiaries, taken as a whole,
after the Effective Time.  The accruals and reserves for taxes reflected in the
Associated Balance Sheet are adequate to cover all Taxes accruable through the
date thereof (including Taxes being contested) in accordance with generally
accepted accounting principles.  No agreements relating to allocating or
sharing of Taxes exist among Associated and its subsidiaries and no tax
indemnities given by Associated or its subsidiaries in connection with a sale
of stock or assets remain in effect.  Neither Associated nor any of its
subsidiaries is required to include in income either (i) any amount in respect
of any adjustment under Section 481 of the Code, or (ii) any installment sale
gain.  Neither Associated nor any of its subsidiaries has made an election
under Section 341(f) of the Code.

         SECTION 3.13.  Brokers.  No broker, finder or investment banker 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 Associated.

         SECTION 3.14.  Accounting and Tax Matters.  To the best knowledge of
Associated, neither Associated nor any of its affiliates has through the date
of this Agreement taken or agreed to take any action that would prevent
Associated from accounting for the business combinations to be effected by the
Merger as a pooling-of-interests or would prevent the Merger from qualifying as
a reorganization under Section 368(a)(1)(A) of the Code.

         SECTION 3.15.  Full Disclosure.  No statement contained in any
document, certificate, or other writing furnished or to be furnished by or at
the direction of Associated to the Company, in or pursuant to the provisions
of, this Agreement contains or shall contain any untrue statement of a material
fact or omits or shall omit to state any material fact necessary, in the light
of the circumstances under which it has been made, in order to make the
statements herein or therein not misleading.


                                   ARTICLE IV

                            COVENANTS OF THE COMPANY


         SECTION 4.01.  Affirmative Covenants.  The Company hereby covenants

the prior written consent of Associated shall have been obtained and except as
otherwise contemplated herein, it will and/or it will cause each Subsidiary to:

         SECTION 4.02.  Negative Covenants.  Except as specifically
contemplated by this Agreement, from the date of this Agreement until the
Effective Time, the Company shall not do, or permit the Subsidiaries to do,
without the prior written consent of Associated, any of the following:

                 (a)      (i) grant any increase in compensation or grant any
         bonuses (incentive or special) to its employees as a class, or to its
         officers or directors, (ii) effect any change in retirement benefits

(a) the Proxy Statement/Prospectus, and (b) as promptly as practicable after

proxy solicitation material or other material relating to the Merger that
constitutes a "prospectus" within the meaning of the Securities Act.
Associated shall also take any action required to be taken under any applicable
Blue Sky Laws in connection with the issuance of the shares of Associated
Common Stock to be issued as set forth in this Agreement and the Company and
the Subsidiaries shall furnish all information concerning the Company and the
Subsidiaries, and the holders of the Company's Common Stock and other
assistance as Associated may reasonably request in connection with such action.

thereunder, and any other applicable federal or state securities laws, (ii) any
applicable federal or state banking laws and (iii) any other applicable law;
provided that Associated and the Company shall cooperate with each other in

         the exercise of full rights of ownership or operation by Associated or

         368(b) of the Code, dated on or about the date that is two business

         regulatory approval, imposes any condition or restriction upon the
         Company or Associated or their respective subsidiaries (or the
         Surviving Corporation or its subsidiaries after the Effective Time),
         including, without limitation, any requirement to raise additional
         capital, which would so materially adversely impact the economic or
         business benefits of the transactions contemplated by this Agreement
         as to render inadvisable the consummation of the Merger.

in Section 9.01 hereof, and neither the Company nor Associated shall have any
liability under this Agreement for damages or otherwise.

remedies at law or equity for breach of this Agreement, the party so found to
have breached this Agreement shall indemnify and reimburse the other parties
for their respective expenses.

         SECTION 8.03.  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,

instrument in writing signed by the parties hereto.

bound thereby.

                                VOTING AGREEMENT

                 THIS VOTING AGREEMENT (this "Agreement"), dated as of December
22, 1995, among the undersigned shareholders (the "Shareholders") of GREATER
COLUMBIA BANCSHARES, INC., a Wisconsin corporation (the "Company"), and
ASSOCIATED BANC-CORP, a Wisconsin corporation ("Associated").

                                    RECITAL

                 The Shareholders, the Company and Associated acknowledge the
following:

                 A.       Concurrent with the execution of this Agreement, the
Company, Associated and Associated Banc-Shares, Inc., a Wisconsin corporation
and a wholly owned subsidiary of Associated ("Holding"), have entered into an
Agreement and Plan of Merger (the "Merger Agreement"), providing for the
business combination transaction contemplated therein pursuant to which the
Company will merge with and into Holding pursuant to the terms and conditions
of the Merger Agreement ("Merger").

                 B.       Upon consummation of the Merger, the Shareholders
will receive shares of Associated Common Stock for each share of Company Common
Stock, par value $1 per share (the "Company Common Stock"), owned by them.

                 C.       The Shareholders own the shares of Company Common
Stock set forth opposite such Shareholder's respective names on Exhibit A
hereto (such shares set forth on Exhibit A, and together with all shares of
Company Common Stock subsequently acquired by any Shareholder during the term
of this Agreement, being referred to as the "Shares").

                 D.       In order to induce Associated to enter into the
Merger Agreement and in consideration of the substantial expenses incurred and
to be incurred by Associated in connection therewith, the Shareholders have
agreed to enter into and perform this Voting Agreement.

                                   AGREEMENTS

                 In consideration of the Recitals and the mutual agreements
which follow, Shareholders, the Company and Associated agree as follows:

                 1.       Agreement to Vote Shares.  Each of the Shareholders
shall vote or cause to be voted, or express a written consent with respect to,
all of such Shareholder's Shares (a) in favor of adoption and approval of the
Merger Agreement and the Merger at every meeting of the Shareholders of the
Company at which such matters are considered and at every adjournment thereof
and in connection with every proposal to take action by written consent with
respect thereto and (b) against any proposal for a Competing Transaction (as
such term is defined in the Merger Agreement) at every meeting of the
shareholders of the Company at which such matters are considered and at every
adjournment thereof and in connection with every proposal to take action by
written consent with respect thereto.

                 2.       No Voting Trusts.  Each of the Shareholders agrees
that such Shareholder will not, nor will such Shareholder permit any entity
under such Shareholder's control to, deposit any of such Shareholder's Shares
in a voting trust or subject any of their Shares to any agreement, arrangement
or understanding with respect to the voting of such Shares inconsistent with
this Agreement.





                                      B-1
<PAGE>   88


                 3.       Limitation on Sales.  During the term of this
Agreement, each Shareholder agrees not to sell, assign, transfer or dispose of
any such Shareholder's Shares.  Notwithstanding the foregoing, any Shareholder
may, during the term of this Agreement, make gifts of Shares to the charitable
organization(s) of his or her choice or to members of his or her immediate
family provided any such charitable organization or family member agrees in
writing to be bound to the terms of this Agreement.

                 4.       Purchase Right.  The Shareholders hereby grants to
Associated the exclusive right ("Purchase Rights") to purchase any or all of
such Shareholders' Shares for a price of $37.3275 per share, payable in cash.
The exercise of the Purchase Rights by Associated, with respect to any amount
of Shares that exceeds 5% of the outstanding voting stock of the Company is
subject to the approval of the Board of Governors of the Federal Reserve System
and any other necessary regulatory approvals.  The Purchase Rights are
exercisable at any time prior to the earlier of the Effective Time, as defined
in the Merger Agreement, or the termination of the Merger Agreement and only
after (a) a material breach by the Company of the Merger Agreement, which
breach is not cured to the reasonable satisfaction of Associated within 10
business days following receipt by the Company of notice of such breach; (b) a
breach by a Shareholder of this Agreement which breach is not cured to the
reasonable satisfaction of Associated within 10 business days following receipt
by such Shareholder of notice of such breach; or (c) the acquisition or overtly
threatened acquisition by any person not related to the current Shareholders of
the Company of more than 5% of the stock of the Company or its subsidiary, The
First National Bank of Portage or of a material portion of the assets of the
Company or The First National Bank of Portage.

         5.      Shareholders' Representations.  Each Shareholder severally
represents that:  (a) such Shareholder has the complete and unrestricted power
and unqualified right to enter into and perform the terms of this Agreement;
(b) this Agreement constitutes a valid and binding agreement with respect to
such Shareholder, enforceable against such Shareholder in accordance with its
terms and (c) such Shareholder owns the number of Shares indicated opposite
such Shareholder's name on Exhibit A hereto, has the sole and unrestricted
voting power with respect to such Shares and such Shares are all of the Shares
directly or indirectly held by such Shareholder.

         6.      Specific Performance and Remedies.  The parties hereto
acknowledge that it will be impossible to measure in money the damage to the
other party(ies) if a party hereto fails to comply with the obligations imposed
by this Agreement and that, in the event of such failure, the other party(ies)
will not have an adequate remedy at law or in damages.  Accordingly, each party
hereto agrees that injunctive relief or other equitable remedy, in addition to
remedies at law or in damages, is the appropriate remedy for any such failure.
No party will oppose the granting of such relief on the basis that the other
party(ies) have an adequate remedy at law.  Each party hereto agrees that it
will not seek, and agrees to waive any requirement for, the securing or posting
of a bond in connection with any other party's seeking or obtaining such
equitable relief.  In addition to all other rights or remedies which any party
hereto may have against any other party hereto who defaults in the performance
of such party's obligations under the Agreement, such defaulting party shall be
liable to the nondefaulting party for all litigation costs and attorneys' fees
incurred by the nondefaulting party(ies) in connection with the enforcement of
any of the nondefaulting party's rights or remedies against the defaulting
party.

         7.      Term of the Agreement; Termination.  The term of this
Agreement shall commence on the date hereof and such term and this Agreement
shall terminate upon the earlier to occur of (a) the Effective Time (as defined
in the Merger Agreement) and (b) the date on which the Merger Agreement is
terminated in accordance with its terms.  Upon such termination, no party shall
have any further obligations or liabilities hereunder; provided, that such
termination shall not relieve any party from liability for any breach of this
Agreement prior to such termination.

         8.      Entire Agreement.  This Agreement supersedes all prior
agreements, written or oral, among the parties hereto with respect to the
subject matter hereof and contains the entire agreement among the parties





                                      B-2
<PAGE>   89


with respect to the subject matter hereof.  This Agreement may not be amended,
supplemented or modified, and no provisions hereof may be modified or waived,
except by an instrument in writing signed by all parties hereto.  No waiver of
any provisions hereof by any party shall be deemed a waiver of any other
provisions hereof by any such party, nor shall any such waiver be deemed a
continuing waiver of any provision hereof by such party.

         9.      Notices.  All notices, requests, claims, demands or other
communications hereunder shall be in writing and shall be deemed given when
delivered personally, upon receipt of a transmission confirmation if sent by
telecopy or like transmission and on the next business day when sent by Federal

           SUBCHAPTER XIII OF THE WISCONSIN BUSINESS CORPORATION LAW

                               DISSENTERS' RIGHTS



         180.1301 DEFINITIONS.

                 In Section Section 180.1301 to 180.1331:

                 (1)      "Beneficial shareholder" means a person who is a
beneficial owner of shares held by a nominee as the shareholder.

                 (lm)     "Business combination" has the meaning given in
Section 180.1130(3).

                 (2)      "Corporation" means the issuer corporation or, if the
corporate action giving rise to dissenters' rights under Section 180.1302 is a
merger or share exchange that has been effectuated, the surviving domestic
corporation or foreign corporation of the merger or the acquiring domestic
corporation or foreign corporation of the share exchange.

                 (3)      "Dissenter" means a shareholder or beneficial
shareholder who is entitled to dissent from corporate action under Section
180.1302 and who exercises that right when and in the manner required by

                 (4)      "Fair value", with respect to a dissenter's shares
other than in a business combination, means the value of the shares immediately

that is the issuer of the shares held by a dissenter before the corporate
action.

                 (5)      Except as provided in Section 180.1833, a shareholder
or beneficial shareholder entitled to dissent and obtain payment for his or her
shares under Section Section 180.1301 to 180.1331 may not challenge the

         written consent to the dissent not later than the time that the

         respect to all shares of which he or she is the beneficial
         shareholder.

meeting notice shall state that shareholders and beneficial shareholders are or
may be entitled to dissenters' rights under Section Section 180.1301 to
180.1331 and shall be accompanied by a copy of those sections.

                 (2)      If corporate action creating dissenters' rights under

shall notify, in writing and in accordance with Section 180.0141, all
shareholders entitled to assert dissenters' rights that the action was
authorized and send them the dissenters' notice described in Section 180.1322.

         180.1321 NOTICE OF INTENT TO DEMAND PAYMENT.

                 (1)      If proposed corporate action creating dissenters'

dissenters' rights shall do all of the following:

                          (a)     Deliver to the issuer corporation before the
         vote is taken written notice that complies with Section 180.0141 of
         the shareholder's or beneficial shareholder's intent to demand payment
         for his or her shares if the proposed action is effectuated.

                          (b)     Not vote his or her shares in favor of the
         proposed action.

Section 180.1301 to 180.1331.

         180.1328 PROCEDURE IF DISSENTER DISSATISFIED WITH PAYMENT OR OFFER.

                 (1)      A dissenter may, in the manner provided in sub. (2),
notify the corporation of the dissenter's estimate of the fair value of his or
her shares and amount of interest due, and demand payment of his or her
estimate, less any payment received under Section 180.1325, or reject the offer
under Section 180.1327 and demand payment of the fair value of his or her
shares and interest due, if any of the following applies:

                          (a)     The dissenter believes that the amount paid
         under Section 180.1325 or offered under Section 180.1327 is less than
         the fair value of his or her shares or that the interest due is
         incorrectly calculated.

                          (b)     The corporation fails to make payment under
         Section 180.1325 within 60 days after the date set under Section
         180.1322 for demanding payment.

                          (c)     The issuer corporation, having failed to
         effectuate the corporate action, does not return the deposited
         certificates or release the transfer restrictions imposed of
         uncertificated shares within 60 days after the date set under Section
         180.1322 for demanding payment.

                 (2)      A dissenter waives his or her right to demand payment
under this section unless the dissenter notifies the corporation of his or her
demand under sub. (1) in writing within 30 days after the corporation made or
offered payment for his or her shares.  The notice shall comply with Section
180.0141.

         180.1330 COURT ACTION.

                 (1)      If a demand for payment under Section 180.1328
remains unsettled, the corporation shall bring a special proceeding within 60
days after receiving the payment demand under Section 180.1328 and petition the
court to determine the fair value of the shares and accrued interest.  If the
corporation does not bring the special proceeding within the 60-day period, it
shall pay each dissenter whose demand remains unsettled the amount demanded.

                 (2)      The corporation shall bring the special proceeding in
the circuit court for the county where its principal office or, if none in this
state, its registered office is located.  If the corporation is a foreign
corporation without a registered office in this state, it shall bring the
special proceeding in the county in this state in which was located the
registered office of the issuer corporation that merged with or whose shares
were acquired by the foreign corporation.

                 (3)      The corporation shall make all dissenters, whether or
not residents of this state, whose demands remain unsettled parties to the
special proceeding.  Each party to the special proceeding shall be served with
a copy of the petition as provided in Section 801.14.

                 (4)      The jurisdiction of the court in which the special
proceeding is brought under sub. (2) is plenary and exclusive.  The court may
appoint one or more persons as appraisers to receive evidence and recommend
decision on the question of fair value.  An appraiser has the power described
in the order appointing him or her or in any amendment to the order.  The
dissenters are entitled to the same discovery rights as parties in other civil
proceedings.

                 (5)      Each dissenter made a party to the special proceeding
is entitled to judgment for any of the following:

                          (a)     The amount, if any, by which the court finds
         the fair value of his or her shares plus interest, exceeds the amount
         paid by the corporation.

<PAGE>   98


                          (b) The fair value, plus accrued interest, of his or
         her shares acquired on or after the date specified in the dissenters'
         notice under Section 180.1322(2)(c), for which the corporation elected
         to withhold payment under Section 180.1327.

         180.1331 COURT COSTS AND COUNSEL FEES.

                 (1)      (a)     Notwithstanding Section Section 814.01 to
         814.04, the court in a special proceeding brought under Section
         180.1330 shall determine all costs of the proceeding, including the
         reasonable compensation and expenses of appraisers appointed by the
         court and shall assess the costs against the corporation, except as
         provided in par. (b).

                          (b)     Notwithstanding Section Section 814.01 and
         814.04, the court may assess costs against all or some of the
         dissenters, in amounts that the court finds to be equitable, to the
         extent that the court finds the dissenters acted arbitrarily,
         vexatiously or not in good faith in demanding payment under Section
         180.1328.

                 (2)      The parties shall bear their own expenses of the
proceeding, except that, notwithstanding Section Section 814.01 to 814.04, the
court may also assess the fees and expenses of counsel and experts for the
respective parties, in amounts that the court finds to be equitable, as
follows:

                          (a)     Against the corporation and in favor of any
         dissenter if the court finds that the corporation did not
         substantially comply with Section Section 180.1320 to 180.1328.

                          (b)     Against the corporation or against a
         dissenter, in favor of any 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 with respect to the
         rights provided by this chapter.

                 (3)      Notwithstanding Section Section 814.01 to 814.04, if
the court finds that the services of counsel and experts for any dissenter were
of substantial benefit to other dissenters similarly situated, the court may
award to these counsel and experts reasonable fees to be paid out of the
amounts awarded the dissenters who were benefited.

Financial Condition

     Total assets of $210,704,000 at September 30, 1995 declined $496,000, or
0.2%, from $211,200,000 at December 31, 1994.

     Total deposits of $170,027,000 at September 30, 1995 reflects a decrease
of $3,101,000, or 1.8%, from December 31, 1994.  Interest-bearing and
noninterest-bearing deposit accounts had both decreased approximately 1.8%


Capital

     Total stockholders' equity increased from $13,640,000 to $14,929,000 at
September 30, 1995 due to income of $1,686,000 a reduction in unrealized losses
on investment securities available for sale of $746,000 reduced by a payment of
dividends of $1,143,000.

     Capital requirements set by federal regulatory agencies establish minimum
capital levels for the Bank.  These guidelines require minimum Tier I capital
of 4%, a Tier I leverage ratio of 4% and total risk-based capital of 8% of
risk-weighted assets.  The Bank was in compliance with all such minimum capital
guidelines at September 30, 1995.

     Set forth below is a comparison of the Bank's September 30, 1995 actual
capital levels with the minimum requirements for well-capitalized and
adequately capitalized banks, as defined by the federal regulatory agencies'
Prompt Corrective Action Rules:

Asset Quality

     The Company continued its commitment to credit quality in 1994.  Net
charge-offs as a percentage of average loans were 0.19%.  Accrual of interest
is discontinued on a loan when management believes, after considering economic
and business conditions and collection efforts, that the borrower's financial
condition is such that collection of interest is doubtful.  As of September 30,
1995, non-accrual loans totaled $255,000 or 0.17% of gross loans.

     As of December 31, 1994, 9.9% of total gross loans or $13,186,000 were
secured by commercial real estate in the Wisconsin Dells area.  All of the
credits in the Wisconsin Dells portfolio are performing according to the
original note terms and management does not anticipate any loan loss exposure.

     Total gross loans increased to $143,663,000 at September 30, 1995 or 7.89%
from December 31, 1994.  The growth was primarily attributable to growth in
loans secured by real estate.  Loans for commercial and agricultural production
totaled $28,727,000 at September 30, 1995, a 2.7% increase from December  31,
1994.  Within the real estate loan classification, loans to finance
construction totaled $9,003,000, an 82% increase from December 31, 1994.
Residential loans increased 7.3% from December 31, 1994 to $42,615,000.  All
other loan categories were relatively unchanged at September 30, 1995 compared
to December 31, 1994.

     At December 31, 1994, the allowance for possible loan losses was
$1,417,000 or 1.06% of gross loans compared with $749,000 or 0.95% of gross
loans on December 31, 1993.  Management considers the allowance more than
adequate to cover possible loan losses in the loan portfolio.  Management
performs a quarterly analysis to reassess the adequacy of the reserve in order
to maintain the allowance at an adequate level to absorb possible future
charge-offs of existing loans.


Asset /Liability Management

     The principal function of asset/liability management is to manage the
balance sheet mix, maturities, repricing characteristics and pricing components
to provide an adequate and stable net interest margin with an acceptable level
of risk over time through interest rate cycles.

     Interest-sensitive assets and liabilities are those that are subject to
repricing within a specific relevant time horizon.  The Bank measures
interest-sensitive assets and liabilities, and their relationship with each
other at terms of immediate, quarterly intervals up to one year, and over one
year.

     Changes in net interest income, other than volume-related, arise when
interest rates on assets reprice in a time frame or interest rate environment
that is different from the repricing period for liabilities.  Changes in net
interest income also arise from changes in the mix of interest earning assets
and interest-bearing liabilities.

     The Bank's strategy with respect to asset/liability management is to
maximize net interest income while limiting its exposure to a potential
downward movement in net margin.  This strategy is implemented by the Bank's
management which takes action based upon its analysis of the Bank's present
positioning, its desired future positioning, economic forecasts, and its goals.

    (1) Bank management believes that Regular Savings, Money Market, and
    NOW Accounts are stable core deposits.  Although these accounts can
    be repriced at any time, management feels a more appropriate treatment
    is to treat these accounts as "90-179 Days" rate sensitive
    liabilities.

Liquidity

     The liquidity position of the Bank is managed to insure that sufficient
funds are available to meet customers' needs for loans and deposit withdrawals.
Liquidity to meet demand is provided by maintaining marketable investment
securities.  At December 31, 1994, available for sale securities were
$36,098,000.  At September 30, 1995, available for sale securities were
$30,762,000. The Bank is a member of the Federal Home Loan Bank system which
provides the Bank with an additional source of liquidity.  During 1991, the
Bank entered into a master contract agreement with the Federal Home Loan Bank
which provides for borrowings up to a maximum of 35% of assets subject to
certain restrictions.

     The loan to deposit ratio for the Bank was 76.1% at December 31, 1994
and 83.7% at September 30, 1995.

     Management is unaware of any recommendations by regulatory authorities,
known trends, events or uncertainties that will have or that are reasonably
likely to have a material effect on the Bank's liquidity.

RESULTS OF OPERATIONS FOR NINE MONTHS ENDED SEPTEMBER 30, 1995 COMPARED WITH
THE NINE MONTHS ENDED SEPTEMBER 30, 1994

Results of Operations Overview

     For the nine months ended September 30, 1995, the Bank's net income
increased from the same period in 1994 by $228,000 or 15.6% to $1,686,000 which
was attributable to operating The First National Bank of Columbus for the
complete nine month period of 1995 and only seven months in 1994.

Net Interest Revenue

     Net interest revenue increased by $643,000 or 11.4% to $6,269,000
principally due to an increase in earning assets and rate sensitive liabilities
of approximately 10%.  The operations of the first national Bank of Columbus,
which was acquired in March 1994, contributed to the increase as 1994 revenue
includes seven months of additional revenue compared to nine months in 1995.

Allowance for Loan Losses

     The amount charged to 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, composition of the loan portfolio and the potential for future
loss.  A total of $35,000 was provided for loan losses in the first nine months
of 1995.  No provision was made in the same period in 1994. Total
non-performing loans decreased $117,000 at September 30, 1995 from a year
earlier.  Non-performing loans totaled $255,000 at September 30, 1995 and
$372,000 at September 30, 1994.  Net charge-offs decreased to $30,735 in 1995
from $226,806 a year earlier due to the first national Bank of Columbus loans
charged-off in 1994 after the merger.

Other Operating Revenue and Expenses

     Other operating revenue increased slightly between periods.  Other
operating expenses increased $177,000 or 4% to $4,583,000 for the nine months
ended September 30, 1995 compared to the same period in 1994.  Included in the
increase in other operating expenses were increases in salaries and employee
benefits of $85,000 due primarily to the acquisition of The First National Bank
of Columbus and inflationary adjustments to compensation.  All other expenses
increased $92,000 or 4%.  The acquisition of The First National Bank of
Columbus contributed to increases in other revenue and other expense.  The
modest increases relative to the change in net interest revenue were due to the
economies of scale achieved by the acquisition.

Income Taxes

     Income tax expense increased $236,000 in the first nine months of 1995
compared to the same period in 1994 due to increase in pretax net income of
$464,000 and decreased nontaxable municipal investments and loan income.

RESULTS OF OPERATIONS FOR YEARS ENDED 1994, 1993 AND 1992

Results of Operations Overview

     For the year ended December 31, 1994, net income was $1,906,000, an
increase of $432,000, or 29.3%, from 1993.  In March 1994, earning assets
increased 36% as a result of the acquisition of the first national Bank of
Columbus.

     For the year ended December 31, 1993, net income was $1,474,000, a
decrease of $22,000, or 1.5%, from the net income of $1,496,000 a year
earlier.

Net Interest Revenue

     Net interest revenue increased by $2,129,000, or 38.1%, to $7,717,000 in
1994.  Total interest income increased 29.4% to $13,475,000 in 1994.  Average
earning assets increased $49,018,000 while average yield decreased from 8.02%
in 1993 to 7.62% in 1994.  Interest expense increased 19.4% to $5,758,000.
Interest-bearing liabilities increased 34.9% to $164,574.  Average rates paid
on such balances fell from 3.95% to 3.5%.  Volume increases are due to the
acquisition of the first national Bank of Columbus.

     Net interest revenue increased by $85,000, or 1.5%, to $5,588,000 in 1993.
Total interest income decreased $601,000 in 1993.  Average earning assets
increased $11,487,000 while average yield decreased from 9.24% in 1992 to 8.02%
in 1993.  Interest expense decreased $686,000 to $4,822,000 in 1993.  While
deposits were rather constant, average rates paid fell rapidly from 4.81% in
1992 to 3.95% in 1993.

     Interest rate spread is the difference between the tax equivalent rate
earned on average earning assets and the rate paid on average interest-bearing
liabilities.  The rate spread was flat improving only 2 basis points in 1994 to
4.06%.  The average yield on earning assets was 7.56% a decrease of  43 basis
points from 1993, however repricing liabilities also decreased the average cost
of interest bearing liabilities to 3.50% in 1994 from 3.95% in 1993, resulting
in the slightly improved spread.

     The interest rate spread decreased of 34 basis points to 4.04% in 1993
compared to 1992.  The average yield on earning assets was 7.99% a decrease of
120 basis points from 1992 due primarily to falling rates.  Repricing
liabilities also decreased the average cost of interest-bearing liabilities to
3.95% in 1993 a decrease of 86 basis points from 1992.

Allowance for Loan Losses

     The Bank's management evaluates the adequacy of the allowance for loan
losses based on an analysis of specific problem loans, as well as on an
aggregate basis.  Provisions charged to expense were none, $171,000 and
$126,000 in 1994, 1993 and 1992 respectively.  The allowance for loan loss
balance as a percent of gross loans was 1.06%, 0.95% and 0.90% at December 31,
1994, 1993 and 1992 respectively.  Management reviews the calculation of the
allowance for loan losses on a quarterly basis and believes that the allowance
for loan losses is adequate.  The allowance for loan losses is maintained at a
level considered adequate to provide for potential future losses.  The level of
the allowance is based on management's periodic and comprehensive evaluation of
the loan portfolio, including past loan experience; current and projected
economic trends; the volume, growth, and composition of the loan portfolio; and
other relevant factors.  Reports of examinations furnished by state and federal
banking authorities are also considered by management in this regard.

     The Bank's management has established the allowance for loan losses to
reduce the gross level of loans outstanding by an estimate of uncollectible
loans.  As loans are deemed uncollectible, they are charged against the
allowance.  A provision for loan losses is expensed against current income on a
monthly basis.  This provision acts to replenish the allowance for loan losses
to accommodate charge-offs and growth in the loan portfolio, thereby
maintaining the allowance at an adequate level.

Other Operating Revenue

     Other operating revenue decreased by $28,000 to $947,000 in 1994.   The
Bank incurred losses in its securities of $135,658 in 1994 compared with gains
of $397,705 in 1993.  Service fees increased by $227,000 attributable to the
acquisition of the first national Bank of Columbus, while other income
increased by $278,000 due to gains realized on the sale of other real estate in
1994.

     Other operating revenue increased by $351,000 to $975,000 in 1993.
Securities gains increased in 1993 by $290,000 from 1992.  Proceeds from sale
of securities held for investment were $18,064,000 during 1993 which resulted
in realized gross gains of $398,000 compared to gross gains of $108,000 in 1992
on proceeds of sales of $2,729,000.  Service fees increased by $30,000
resulting primarily from a $19,000 increase in safe deposit rental and $10,000
in commissions related to sales of annuities which were introduced in 1993.
Other income increased by $31,000 due to increases in NSF and returned check
charges which increased $29,000 in 1993.

Other Operating Expenses

     Other operating expenses increased by $1,640,000, or 37.9%, to $5,972,000
in 1994.  Salaries and employee benefits increased $954,000 which relates to
additional staff from the acquisition of the first national Bank of Columbus.
Computer services expenses increased $7,000 or 2.2%.  Furniture and equipment
expenses increased $74,000 as a result of increased depreciation on assets
acquired from The First National Bank of Columbus.  All other expenses
increased an aggregate of $510,000 or 43.6% due to the acquisition which
included the following: amortization of goodwill and other intangibles
increased $236,000; FDIC insurance increased $91,000; and other expenses
increased $183,000.

     Other operating expenses increased by $462,000, or 11.9%, to $4,332,000 in
1993.  Salaries and employee benefits increased  12.3% which related to
increases in compensation and increased staffing level requirements.  Computer
services expenses decreased $9,000 or 2.7%.  Occupancy, furniture and equipment
expense increased to $662,000 in 1993 from $537,000 in 1992.  The increase is
attributable to various factors including increases in depreciation, repairs,
personal property taxes, utilities, and insurance.  All other expenses
increased $105,000, or 9.9% attributable to Company legal and accounting costs
relating to its stock offering and increased FDIC assessment costs.

Income Taxes

     Income tax expense increased $200,000 in 1994 compared to 1993 primarily
due to the increase in pretax income of $632,000.  Tax exempt income increased
by $242,000 along with an increase in nondeductible expenses of $236,000
related to the acquisition of The First National Bank of Columbus.

Current Accounting Issues

1)  Fair value of financial instruments

      The Financial Accounting Standards Board (FASB) Statement No. 107,
      Disclosures About Fair Value of Financial Instruments, requires
      disclosure of fair value information about financial instruments, whether
      or not recognized on the balance sheet, for which it is practical to
      estimate that value.  Statement No. 107 excludes certain financial
      instruments and all nonfinancial instruments from its disclosure
      requirements.  This statement is effective for the Bank's year ending
      December 31, 1995.

2)  Impairment of loans

      The FASB has issued Statement No. 114, Accounting by Creditors for
      Impairment of a Loan.  Statement No. 114 requires that impaired loans
      that are within the scope of this statement be measured based on the
      present value of expected future cash flows discounted at the loan's
      effective interest rate or, as a practical expedient, at the loan's
      observable market price or the fair value of the collateral if the loan
      is collateral dependent.  A loan is impaired when it is probable the
      creditor will be unable to collect all contractual principal and interest
      payments due in accordance with the terms of this loan agreement.  This
      statement is effective for the Bank's year ending December 31, 1995.
      Management has determined this Statement will have no material effect on
      the financial statements.


3)  Accounting by creditors for impairment of a loan-income recognition and
    disclosures

      The FASB has issued FASB Statement No. 118 which amends certain
      provisions of FASB Statement No. 114 relating to income recognition and
      other required disclosures of impaired loans.  This statement is
      effective for the Bank's year ending December 31, 1995.  Management has
      determined this Statement will have no material effect on the financial
      statements.


4)  Accounting for Mortgage Servicing Rights

      FASB has issued Statement No. 122, Accounting for Mortgage Servicing
      Rights.  Statement No. 122 amends certain provisions of Statement No. 65
      to eliminate the accounting distinction between rights to service
      mortgage loans for others that are acquired through loan origination
      activities and those acquired through purchase transactions.  If a
      mortgage banking enterprise sells or securitizes mortgage loans and
      retains the mortgage servicing rights, the enterprise should allocate the
      total cost of mortgage loans to the mortgage servicing rights and the
      loans (without the mortgage servicing rights) based on their relative
      fair values.  Any costs allocated to mortgage servicing rights should be
      recognized as a separate asset.  This Statement is effective for the
      Company's year ending December 31, 1996.  Management has determined this
      Statement will have no material effect on the financial statements.

Notes:

   
(a) Accrual of interest is discontinued on a loan when management
    believes, after considering economic and business decisions and
    collection efforts, that the borrower's financial condition is such
    that collection of interest is doubtful.

   
(b) If interest on the nonaccrual loans had been accrued, such income
    would have approximated $60,896, $5,157, $7,807, $-0- and $-0- at
    December 31, 1994, 1993, 1992, 1991 and 1990 respectively.  There was
    no interest income on these loans, which is recorded only when
    received.

   
(c) As of December 31, 1994, management, to the best of its knowledge, is
    not aware of any significant loans or segments of the loan portfolio
    not included above, where there are serious doubts as to ability of
    the borrowers to comply with the present loan repayment terms.   There
    were no restructured loans for each of the presented years.

consideration of 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 borrowers' ability to pay.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


Board of Directors
Greater Columbia Bancshares, Inc.
Portage, Wisconsin

            We have audited the accompanying consolidated balance sheets of
Greater Columbia Bancshares, Inc. and subsidiary as of December 31, 1994 and
1993, and the related consolidated statements of income, changes in
stockholders' equity, and cash flows for the years ended December 31, 1994,
1993 and 1992.  These consolidated financial statements are the responsibility
of the Company's management.  Our responsibility is to express an opinion on
these consolidated financial statements based on our audits.
            We conducted our audits in accordance with generally accepted
auditing standards.  Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the consolidated financial
statements are free of material misstatement.  An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the
consolidated 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
Greater Columbia Bancshares, Inc. and subsidiary at December 31, 1994 and 1993,
and the results of its operations, and its cash flows for the years ended
December 31, 1994, 1993 and 1992, in conformity with generally accepted
accounting principles.
            As described in Note B to the consolidated financial statements, on
January 1, 1994, the Company changed its method of accounting for investments
in debt and marketable equity securities.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        December 31, 1994, 1993 and 1992

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting principles of Greater Columbia Bancshares, Inc. conform to those
generally accepted and to general practices within the banking industry.

The significant accounting policies affecting the consolidated financial
statements are summarized below to assist the reader in understanding the
financial information presented in this report.

1.  Consolidation

The consolidated financial statements of Greater Columbia Bancshares, Inc.
include the accounts of its wholly owned subsidiary, The First National Bank of
Portage.  The First National Bank of Portage includes the accounts of its
wholly owned subsidiary, Portage Investments, Inc.  All significant
intercompany accounts and transactions have been eliminated in the consolidated
financial statements.

2.  Nature of banking activities

The consolidated income of Greater Columbia Bancshares, Inc. is principally
from income of its wholly owned subsidiary.  The subsidiary Bank grants
agribusiness, commercial and residential loans to customers throughout the
State of Wisconsin, concentrating in the counties surrounding the Bank's eleven
locations.  Although the Bank has a diversified loan portfolio, the ability of
its debtors to honor their contracts is dependent on the economic conditions of
the counties surrounding the subsidiary Bank.

3.  Cash and cash equivalents

For purposes of reporting cash flows, cash and cash equivalents include cash on
hand, amounts due from banks, federal funds sold, and investments with original
maturities of three months or less.  Generally, federal funds are sold for
one-day periods.  Cash flows from loans, federal funds purchased, deposits and
other short-term borrowings are reported net.

The Bank maintains amounts due from banks which, at times, may exceed federally
insured limits.  The Bank has not experienced any losses in such accounts.

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

4. Investment in debt and marketable equity securities

The Company accounts for debt and equity securities in accordance with FASB
Statement No. 115.  This statement requires that management determine the
appropriate classification of securities at the date of adoption and thereafter
as each individual security is acquired.  In addition, the appropriateness of
such classification should be reassessed at each balance sheet date.  The
classifications and related accounting policies under FASB Statement No. 115
are as follows:

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.  Available for sale securities also
       includes equity securities.  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 stockholders' equity.  Realized gains or losses, determined on the
       basis of the cost of specific securities sold, are included in earnings.

Held to maturity securities:

       Securities classified as held to maturity are those debt securities the
       Company has both the intent and ability to hold to maturity regardless
       of changes in market conditions, liquidity needs or changes in general
       economic conditions.  These securities are carried at cost adjusted for
       amortization of premium and accretion of discount, computed by the
       interest method over their contractual lives.

       Transfers of debt securities into the held to maturity classification
       (if any) from the available for sale classification are made at fair
       value on the date of transfer.  The unrealized holding gain or loss on
       the date of transfer is retained in the separate component of
       stockholders' equity and in the carrying value of the held to maturity
       securities.  Such amounts are amortized over the remaining contractual
       lives of the securities by the interest method.

Securities held for investment:

       Prior to the accounting change discussed in Note B, securities held for
       investment were stated at cost adjusted for amortization of premiums and
       accretion of discounts which were recognized as adjustments to interest
       income.  Gains or losses on disposition were based on the net proceeds
       and the adjusted carrying amount of the securities sold, using the
       specific identification method.  Mutual funds were carried at the lower
       of their aggregate cost or market value, determined as of the report
       date.  Any unrealized loss was credited to a valuation allowance for
       marketable equity securities and charged to a separate account within
       the equity section.

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued)

5.  Loans

Loans are stated at the amount of unpaid principal, reduced by the allowance
for loan losses.  Interest on loans is calculated by using the simple interest
method on daily balances of the principal amount outstanding.  Accrual of
interest is discontinued on a loan when management believes, after considering
economic and business condi-tions and collection efforts, 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.  Accrual of interest is
generally resumed when the customer is current on all principal and interest
payments and has been paying on a timely basis for a period of time.

6.  Allowance for loan losses

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 the collectibility of the principal is
unlikely.  The allowance is an amount that management believes will be adequate
to absorb possible losses on existing loans that may become uncollectible,
based on evaluation of the collectibility of loans and prior loan loss
experience.  The evaluations take 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
borrowers' 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.

7.  Office buildings and equipment

Depreciable assets are stated at cost less accumulated depreciation.
Provisions for depreciation are computed on straight-line and accelerated
methods over the estimated useful lives of the assets, which are 30 years for
office buildings and 3 to 20 years for equipment.

8.  Income taxes

The Company uses the asset and liability approach to financial accounting and
reporting for income taxes.  Deferred income tax assets and liabilities are
computed annually for differences between the financial statement and tax bases
of assets and liabilities that will result in taxable or deductible amounts in
the future based on enacted tax laws and rates applicable to the periods in
which the differences are expected to affect taxable income.  The differences
relate principally to the reserve for loan losses, the accruals for deferred
compensation expense, fixed assets and unrealized gains and losses on available
for sale securities.  Valuation allowances are established when necessary to
reduce deferred tax assets to the amount expected to be realized.

 9. Earnings per share

Earnings per share are based on the Company's weighted average number of shares
outstanding during the year.

 10.  Emerging accounting standards

 Fair value of financial instruments:

       Financial Accounting Standards Board (FASB) Statement No. 107,
       Disclosures About Fair Value of Financial Instruments, requires
       disclosure of fair value information about financial instruments,
       whether or not recognized on the balance sheet, for which it is
       practicable to estimate that value.  Statement No. 107 excludes certain
       financial instruments and all nonfinancial instruments from its
       disclosure requirements.  This statement is effective for the Company's
       year ending December 31, 1995.

 Impairment of loans:

       The FASB has issued Statement No. 114, Accounting by Creditors for
       Impairment of a Loan.  Statement No. 114 requires that impaired loans
       that are within the scope of this statement be measured based on the
       present value of expected future cash flows discounted at the loan's
       effective interest rate or, as a practical expedient, at the loan's
       observable market price or the fair value of the collateral if the loan
       is collateral dependent.  A loan is impaired when it is probable the
       creditor will be unable to collect all contractual principal and
       interest payments due in accordance with the terms of the loan
       agreement.  This statement is effective for the Company's year ending
       December 31, 1995.  Management has determined this Statement will have
       no material effect on the financial statements.

 Accounting by creditors for impairment of a loan-income recognition and
 disclosures:

       The FASB has issued FASB Statement No. 118 which amends certain
       provisions of FASB Statement No. 114 relating to income recognition and
       other required disclosures of impaired loans.  This statement is
       effective for the Company's year ending December 31, 1995.  Management
       has determined this Statement will have no material effect on the
       financial statements.

 Accounting for Mortgage Servicing Rights:

       FASB has issued Statement No. 122, Accounting for Mortgage Servicing
       Rights.  Statement No. 122 amends certain provisions of Statement No. 65
       to eliminate the accounting distinction between rights to service
       mortgage loans for others that are acquired through loan origination
       activities and those acquired through purchase transactions.  If a
       mortgage banking enterprise sells or securitizes mortgage loans and
       retains the mortgage servicing rights, the enterprise should allocate
       the total cost of mortgage loans to the mortgage servicing rights and
       the loans (without the mortgage servicing rights) based on their
       relative fair values.  Any costs allocated to mortgage servicing rights
       should be recognized as a separate asset.  This Statement is effective
       for the Company's year ending December 31, 1996.  Management has
       determined this Statement will have no material effect on the financial
       statements.

11.  Reclassifications

Certain of the 1993 and 1992 amounts have been reclassified to conform with the
1994 presentation.  These reclassifications had no effect on net income or
stockholders' equity.

NOTE B - ACCOUNTING CHANGE

As of January 1, 1994, the Company changed its method for accounting for debt
and equity securities in accordance with FASB Statement No. 115.  As provided
by this statement, 1993 comparative financial statements have not been restated
for the change in accounting principle.  The January 1, 1994 balance of
stockholders' equity was increased by $135,255, net of the $69,677 related tax
effect, to recognize the net unrealized holding gain on securities at that
date.

NOTE C - CASH AND DUE FROM BANKS

The Company's bank subsidiary is required to maintain certain vault cash and
reserve balances with the Federal Reserve Bank based upon a percentage of
deposits.  These requirements approximated $1,182,000 and $740,000 at December
31, 1994 and 1993 respectively.

   Loans on which the accrual of interest has been discontinued or reduced
   amounted to $368,140 and $151,689 at December 31, 1994 and 1993
   respectively.  If interest on those loans had been accrued, such income
   would have approximated $60,896, $5,157 and $7,807 for 1994, 1993 and 1992
   respectively.  There was no interest income on these loans, which is
   recorded only when received.

   Certain directors, executive officers, and principal shareholders of the
   Company and their related interests, had loans outstanding in the aggregate
   amounts of $1,597,618 and $1,732,326 at December 31, 1994 and 1993
   respectively.  During 1994, $306,094 of new loans were made and repayments
   totaled $440,802.  These loans were made on substantially the same terms,
   including interest rates and collateral, as those prevailing at the same
   time for comparable transactions with other persons and did not involve more
   than normal risks of collectibility or present other unfavorable features.

NOTE N - LONG-TERM BORROWINGS (continued)

During 1991, the Company entered into a master contract agreement with the
Federal Home Loan Bank (FHLB) which provides for borrowings up to a maximum of
35% of assets subject to certain restrictions. The indebtedness is evidenced by
a master contract dated December 23, 1991.  FHLB provides both fixed and
floating rate advances.  Floating rates are tied to short-term market rates of
interest, such as Fed funds or Treasury Bill rates.  Fixed rate advances are
priced in reference to market rates of interest, namely the rates that FHLB
pays to borrowers at various maturities.

The following table indicates advances outstanding and the applicable interest
rates and maturity dates.  Interest is payable monthly with quarterly principal
payments.

NOTE P - PENSION PLAN

The Company has a defined benefit pension plan covering substantially all of
its employees.  The benefits are based on years of service and the employees's
average monthly pay received during any period of five consecutive years which
gives the highest average.  The Company's funding policy is to have the
actuaries provide management with both a minimum and a maximum pension
contribution for the plan year.  Management then decides each year the amount
of the contribution which will be made from within the range provided by the
actuaries.

There has been a plan curtailment during the period ended December 31, 1994 due
to the benefit accrual freeze as of December 31, 1994.  We have reflected the
curtailment as of the October 1, 1994 measurement date.

The following table sets forth the Plan's funded status at December 31, 1994
and 1993.

NOTE Q - COMMITMENTS, CONTINGENCIES AND CREDIT RISK

 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.

 The Subsidiary Bank 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 Bank's exposure to credit loss in the event of nonperformance by the other
 party to the financial instrument for commitments to extend credit and standby
 letters of credit is represented by the contractual notional amount of those
 instruments.  The Bank uses the same credit policies in making commitments and
 issuing letters of credit as it does for on-balance-sheet instruments.

 A summary of the contract or notional amount of the Bank's exposure to
 off-balance-sheet risk as of December 31, 1994 and 1993 is as follows:

NOTE Q - COMMITMENTS, CONTINGENCIES AND CREDIT RISK (continued)

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee.  Since many of the commitments are expected
to expire without being drawn upon, the total commitment amounts do not
necessarily represent future cash requirements.  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.  The Bank evaluates each customer's credit worthiness
on a case-by-case basis.  The amount of collateral obtained, if deemed
necessary by the Bank upon extension of credit, is based on management's credit
evaluation of the counterparty.  Collateral held varies but may include
accounts receivable, inventory, property and equipment, and income-producing
commercial properties.

NOTE R - STOCK SPLIT AND STOCK OFFERING

On September 1, 1993, the Board of Directors approved a 4 for 1 stock split to
be accomplished by a 300% stock dividend payable of the Company's $1 par value
common stock.  As a result of the stock split, 485,532 additional shares were
issued, and retained earnings were reduced by $485,532.  All share information,
common stock and retained earnings, and earnings per share, has been restated
for the split.

The Company offered to Wisconsin residents who were holders of record at the
close of business October 1, 1993 of its outstanding common stock, the right to
purchase an additional 260,000 shares at $23.  On November 15, 1993, the
Company had received consideration for all 260,000 shares and recorded the
additional capital net of $14,096 in cost relating to the offering.

NOTE S - REGULATORY CAPITAL REQUIREMENTS

The Federal Reserve Board and other bank regulatory agencies have adopted
risk-based capital guidelines for banks and bank holding companies.  The main
objectives of the risk-based capital framework are to provide a more consistent
system for comparing capital positions of banking organizations and to take
into account the different risks among banking organizations' assets and
off-balance-sheet items.  Bank regulatory agencies have supplemented the
risk-based capital standard with a leverage ratio for Tier 1 capital to total
reported assets.  The minimum leverage ratio standard is 3 percent.  Depending
upon the judgment of the various regulatory agencies, a greater leverage ratio
may be required based upon the relative risk of the organization.

Below is a comparison of the Bank's 1994 actual with the minimum requirements
for well-capitalized and adequately capitalized banks, as defined by the
federal regulatory agencies' Prompt Corrective Action Rules:

NOTE T - RETAINED EARNINGS

    The principal source of income and funds of Greater Columbia Bancshares,
    Inc. are dividends from its subsidiary, The First National Bank of Portage.
    The bank subsidiary, as a national bank, is prohibited from declaring or
    paying any dividends without prior regulatory approval in an amount greater
    than $166,595.  Maintenance of adequate capital at the subsidiary bank
    effectively restricts potential dividends to an amount less than $166,595.

    As the result of an agreement signed by the Company upon the issuance of
    the notes payable during 1994, the Company is further precluded from paying
    dividends to its shareholders without the prior written consent of the
    lending bank.  (See Note N).

NOTE U - BUSINESS ACQUISITIONS

In April 1992, The First National Bank of Portage acquired, for $6,363,840, the
business and certain assets and liabilities of Peoples State Bank of
Pittsville.  This acquisition has been accounted for as a purchase and,
accordingly, the acquired assets and liabilities have been recorded at their
estimated fair values at date of acquisition.  The operating results of this
acquisition are included in the Company's consolidated results of operations
from the date of acquisition.

In March 1994, Greater Columbia Bancshares, Inc. acquired, for $10,797,150,
100% of 1st Columbia Corp. stock.  1st Columbia Corp.'s principal asset was The
First National Bank of Columbus, which was liquidated into The First National
Bank of Portage on the date of the acquisition.  This acquisition has been
accounted for as a purchase and, accordingly, the acquired assets and
liabilities have been recorded at their estimated fair values at date of
acquisition.  The operating results of this acquisition are included in the
Company's consolidated results of operations from the date of acquisition.

The following unaudited pro-forma summary presents the consolidated results of
operations of the Company as if the acquisitions had occurred at the beginning

  The above amounts are based upon certain assumptions and estimates which the
  Company believes are reasonable, and do not reflect any benefit from
  economies which might be achieved from combined operations.  The pro-forma
  results do not necessarily represent results which would have occurred if the
  acquisitions had taken place on the basis assumed above, nor are they
  indicative of the results of future combined operations.

NOTE A - GENERAL

   The accounting and reporting policies of Greater Columbia Bancshares,
   Inc. and Subsidiary (the "Company") conform to generally accepted accounting
   principles and to general practices within the banking industry. 
   Significant accounting policies used by the Company are summarized in Note A

   are of a normal recurring nature, and, in the opinion of management,
   necessary for a fair statement of results for the interim periods.  The
   operating results for the nine months ended September 30, 1995 are not
   necessarily indicative of the results which may be expected for the entire
   year.  The accompanying condensed financial statements should be read in
   conjunction with the Company's December 31, 1994 and 1993 financial
   statements and related notes.

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Registrant is incorporated under the Wisconsin Business
Corporation Law (the "WBCL").  Under Section 180.0851 of the WBCL, the
Registrant shall indemnify a director or officer, to the extent such person is
successful on the merits or otherwise in the defense of a proceeding, for all
reasonable expenses incurred in the proceeding, if such person was a party to
such proceeding because he or she was a director or officer of the Registrant.
In all other cases, the Registrant shall indemnify a director or officer
against liability incurred in a proceeding to which such person was a party
because he or she was a director or officer of the Registrant; unless liability
was incurred because he or she breached or failed to perform a duty owed to the
Registrant and such breach or failure to perform constitutes:  (i) a willful
failure to deal fairly with the Registrant 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 director or officer had
reasonable cause to believe his or her conduct was lawful or no reasonable
cause to believe his or her conduct was unlawful; (iii) a transaction from
which the director or officer derived an improper personal profit; or (iv)
willful misconduct.  Section 180.0858 of the WBCL provides that subject to
certain limitations, the mandatory indemnification provisions do not preclude
any additional right to indemnification or allowance of expenses that a
director or officer may have under the Registrant's articles of incorporation,
bylaws, a written agreement between the director or officer and the Registrant
or a resolution of the Board of Directors or adopted by majority vote of the
Registrant's shareholders.

         Section 180.0859 of the WBCL provides that it is the public policy of
the State of Wisconsin to require or permit indemnification, allowance of
expenses and insurance to the extent required or permitted under Sections
180.0850 to 180.0858 of the WBCL for any liability incurred in connection with
a proceeding involving a federal or state statute, rule or regulation
regulating the offer, sale or purchase of securities.

         The Registrant's Articles of Incorporation contains no provisions in
relation to the indemnification of directors and officers of the Registrant.

         Article XI of the Registrant's By-laws ("Article XI") authorizes
indemnification of officers and directors of the Registrant consistent with the
description of the indemnification provisions in Section 180.0851 of the WBCL
as described above.  Article XI provides that the Registrant shall indemnify a
director, officer, employee or agent of the Registrant to the extent such
individual has been successful on the merits or otherwise in the defense of any
threatened, pending or completed civil, criminal, administrative or
investigative action, suit, arbitration or other proceeding, whether formal or
informal (including, but not limited to, any act or failure to act alleged or
determined (i) to have been negligent, (ii) to have violated the Employee
Retirement Income Security Act of 1974; or (iii) to have violated Sections
180.0832, 180.0833 and 180.1202 of the WBCL, or any successor thereto,
regarding loans to directors, unlawful distributions and distributions of
assets, which involves foreign, federal, state or local law and which is
brought by or in the right of the Registrant or by any other person or entity,
to which the director, officer, employee or agent was a party because he or she
is a director, officer, employee or agent.  In all other cases, the Registrant
shall indemnify a director, officer, employee or agent of the Registrant
against liability and expenses incurred by such person in a proceeding unless
it shall have been proven by final judicial adjudication that such person
breached or failed to perform a duty owed to the Registrant under the
circumstances described above as set forth in Section 180.0851 of the WBCL.
Article XI defines a "director, officer, employee or agent" as (i) a natural
person who, is or was a director, officer, employee or agent of the Registrant,
(ii) a natural person who, while a director, officer, employee or agent of the
Registrant, is or was serving either pursuant to the Registrant's specific
request or as a result of the nature of such person's duties to the Registrant
as a director, officer, partner, trustee, member of any governing or decision
making committee, employee or agent of another corporation or foreign
corporation, partnership, joint venture, trust or other enterprise and (iii) a
person who, while a director,





                                      II-1
<PAGE>   158


officer, employee or agent of the Registrant, is or was serving an employee
benefit plan because his or her duties to the Registrant also impose duties on,
or otherwise involve services by, the person to the plan or to participants in
or beneficiaries of the plan.  Unless the context requires otherwise, Article
XI indemnification extends to the estate or personal representative of a
director, officer, employee or agent.

         All officers, directors, employees and agents of controlled
subsidiaries of the Registrant shall be deemed for purposes of Article XI to be
serving as such officers, directors, employees and agents at the request of the
Registrant.  The right to indemnification granted to such officers and
directors by Article XI is not subject to any limitation or restriction imposed
by any provision of the Articles of Incorporation or Bylaws of a controlled
subsidiary.  For purposes of Article XI, a "controlled subsidiary" means any
corporation at least 80% of the outstanding voting stock of which is owned by
the Registrant or another controlled subsidiary of the Registrant.

         Upon written request by a director, officer, employee or agent who is
a party to a proceeding, the Registrant shall pay or reimburse his or her
reasonable expenses as incurred if the director, officer, employee or agent
provides the Registrant with:  (i) a written affirmation of his or her good
faith belief that he or she is entitled to indemnification under Article XI;
and (ii) a written undertaking to repay all amounts advanced without interest
to the extent that it is ultimately determined that indemnification under
Article XI is prohibited.  The Registrant shall have the power to purchase and
maintain insurance on behalf of any person who is a director, officer, employee
or agent against any liability asserted against or incurred by the individual
in any such capacity arising out of his or her status as such, regardless of
whether the Registrant is required or authorized to indemnify or allow expenses
to the individual under Article XI.

         The right to indemnification under Article XI may be amended only by a
majority vote of the shareholders and any reduction in the right to
indemnification may only be prospective from the date of such vote.

ITEM 22.  UNDERTAKINGS.

         (a)(1)  The undersigned Registrant hereby undertakes:

                 (i)  To file, during any period in which offers or sales are
                 being made, a post-effective amendment to this registration
                 statement:  (x) to include any prospectus required by Section
                 10(a)(3) of the Securities Act of 1933, as amended (the
                 "Securities Act"); (y) 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; (z) 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.

                 (ii)  That, for the purpose of determining any liability under
                 the Securities Act, 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 such time shall be deemed to be the initial bona
                 fide offering thereof.

                 (iii)  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.

                 (2)      The undersigned registrant hereby undertakes that,
         for purposes of determining any liability under the Securities Act,
         each filing of the registrant's annual report pursuant to Section
         13(a) or Section 15(d) of the Securities Exchange Act of 1934, as
         amended (the "Exchange Act") (and, where applicable, each filing of an
         employee benefit plan's annual report to Section 15(d) of the Exchange
         Act), 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.

                 (3)      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 underwriters, in
         addition to the information called for by the other items of the
         applicable form.

                 (4)      The registrant undertakes that every prospectus (i)
         that is filed pursuant to paragraph (3) immediately preceding, or (ii)
         that purports to meet the requirements of section 10(a)(3) of the
         Securities 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, 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.

                 (5)      Insofar as indemnification for liabilities arising
         under the Securities Act may be permitted to directors, officers and
         controlling persons of the registrant pursuant to the foregoing
         provisions, or otherwise, the registrant has been advised that in the
         opinion of the Securities and Exchange Commission such indemnification
         is against public policy as expressed in the Securities 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

     Re:  ASSOCIATED BANC-CORP:  REGISTRATION STATEMENT ON FORM S-4


Gentlemen:

     We have acted as legal counsel to Associated Banc-Corp, a Wisconsin
corporation (the "Registrant"), in connection with the preparation of the
Registration Statement filed on February 2, 1996 on Form S-4 with exhibits with
the Securities and Exchange Commission (the "Registration Statement"), relating
to the registration of 967,725 shares of the Registrant's common stock $0.01
par value ("Common Stock").  The shares of Common Stock are being issued in
connection with the merger of Greater Columbia Bancshares, Inc. with and into
Associated Banc-Shares, Inc., a wholly-owned subsidiary of the Registrant.  We
have reviewed such records, documents and matters of law as we have deemed
necessary to render this opinion.  We have also participated in conversations
with officers of the Registrant during which facts material to the opinions
expressed herein were discussed.  We have assumed such factual matters to be
true and correct.

     In making our examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to originals of all documents submitted to us as certified or
photostatic copies and the capacity of each party executing a document to so
execute such document.

     An opinion of counsel is predicated upon all of the facts and conditions
as set forth therein and is based upon counsel's analysis of the statutes,
regulatory interpretations and case law in effect as of the date of this
opinion.  It is neither a guarantee of the current status of the law nor should
it be accepted as a guarantee that a court of law or an administrative agency
will concur in the opinion.

      Based upon the foregoing and assuming the accuracy of the statements
regarding the Registrant and the conduct of its business all as set forth in
its Registration Statement, it is our opinion that the Common Stock, when
issued as provided under applicable Wisconsin law, the Registration Statement,
and the Registrant's Articles of Incorporation and By-laws, will be validly
issued, fully paid and non-assessable except as such shares may be subject to
Section 180.0622(2)(b) of Wisconsin Business Corporation Law.

     We do not find it necessary for the purpose of this opinion, and
accordingly we do not purport to cover herein, the application of the
securities or "Blue Sky" laws of the various states to the issuance of the
Common Stock.

     This opinion is furnished to you in connection with the filing of the
Registration Statement, and is not to be used, circulated, quoted or otherwise
relied upon for any other purpose.

     We are licensed to practice only in Illinois and no opinion is expressed
by us herein as to laws of other jurisdictions.  This opinion is limited to the
matters expressly set forth herein, and no opinion is to be implied or may be
inferred beyond the others expressly so stated.

     We hereby consent to the references to this firm and the inclusion of the
legality opinion as an exhibit to the Registration Statement.

                          Very truly yours,

                          /s/ Saitlin, Patzik, Frank & Samotny Ltd.

Dear Board Members:

In connection with the closing of the proposed merger ("Merger") of Greater
Columbia Bancshares, Inc., a Wisconsin corporation (the "Company"), into
Associated Banc-Shares, Inc., a Wisconsin corporation ("Holding") and a
wholly-owned subsidiary of Associated Banc-Corp, a Wisconsin corporation
("Associated"), you have requested the opinion of KPMG Peat Marwick LLP
("KPMG") with respect to certain federal income tax consequences of the Merger.
The Merger contemplates the acquisition by Holding of all the assets and
liabilities of the Company in exchange for common stock, $0.01 par value, of
Associated ("Associated Common Stock") pursuant to an Agreement and Plan of
Merger, dated as of December 22, 1995 (the "Agreement"), entered into by the
Company, Associated and Holding.

The opinion expressed in this letter is based on the Internal Revenue Code of
1986, as amended (the "Code"), the Income Tax Regulations promulgated by the
Treasury Department thereunder and judicial authority reported as of the date
hereof.  We have also considered the position of the Internal Revenue Service
(the "Service") reflected in published and private rulings.  Although we are
not aware of any pending changes to these authorities that would alter our
opinions, there

can be no assurance that future legislative or administrative changes, court
decisions or Service interpretations will not significantly modify the
statements or opinions expressed herein.  Unless specifically requested
otherwise, KPMG undertakes no responsibility to update this opinion letter in
the event of any such change or modification.  Although the conclusions
contained herein are based upon our best interpretation of existing sources of
law and express what we believe a court would properly conclude if presented
with these issues, no assurance can be given that such interpretations would be
followed if they were to become the subject of judicial or administrative
proceedings.  We express no opinion herein as to any issue of federal law other
than those specifically considered herein.  We also do not express any opinion
as to any issue of state or local law.

For the purposes indicated above, and based upon our review, the conditions set
forth below, and representations made to us by the Company, Associated and
Holding, it is the opinion of KPMG that:

    (1)    Provided the Merger qualifies as a statutory merger under applicable
           law, the merger of the Company into Holding, pursuant to the
           Agreement, will constitute a reorganization within the meaning of
           section 368(a)(1)(A) and section 368(a)(2)(D) of the Code.  The
           Company, Associated and Holding will each be considered "a party to
           a reorganization" within the meaning of section 368(b) of the Code
           for purposes of this reorganization;

    (2)    No gain or loss will be recognized by the Company on the transfer of
           substantially all its assets to Holding in exchange for shares of
           Associated Common Stock, cash to be paid to the shareholders of the
           Company in lieu of fractional share interests of Associated Common
           Stock, and the assumption by Holding of the liabilities of the
           Company (Code sections 361(a) and 357(a));

    (3)    The basis of the Company assets to be received by Holding will be
           the same as the basis of such assets in the hands of the Company
           immediately prior to the Merger (Code section 362(b));

    (4)    The holding period of the Company assets in the hands of Holding
           will include the period during which such assets were held by the
           Company (Code section 1223(2));

    (5)    No gain or loss will be recognized by Associated or Holding upon the
           receipt by

           Holding of substantially all the Company assets in exchange for
           shares of Associated Common Stock, cash to be paid to the
           shareholders of the Company in lieu of fractional share interests of
           Associated Common Stock, and the assumption by Holding of the
           liabilities of the Company (Regulation 1.1032-2);

    (6)    No gain or loss will be recognized by the holders of Company common
           stock, $1.00 par value per share, upon the exchange of such stock
           soley for shares of Associated Common Stock, including any
           fractional share interest to which they may be entitled (Code
           section 354(a)(1));

    (7)    The basis of the Associated Common Stock (including any fractional
           share interests to which they may be entitled) which is received by
           Company shareholders will be the same as the basis of the Company
           common stock surrendered in exchange therefore (Code section
           358(a)(1));

    (8)    The holding period of Associated Common Stock (including any
           fractional share interests to which they may be entitled) which is
           received by a Company shareholder will include the period during
           which the Company common stock surrendered in exchange therefore was
           held, provided that the Company common stock is held as a capital
           asset in the hands of the Company shareholder on the date of the
           exchange (Code section 1223(1));

    (9)    The payment of cash in lieu of fractional share interests of
           Associated Common Stock will be treated as if the fractional shares
           were distributed as part of the exchange and then redeemed by
           Associated.  These cash payments will be treated as having been
           received as distributions in full payment in exchange for the
           fractional shares redeemed, subject to the provisions and
           limitations of section 302(a) of the Code (Rev. Rul. 66-365, 1966-2
           C.B. 116; Rev. Proc. 77-41, C.B. 574);

    (10)   Holding will succeed to and take into account, as of the effective
           date of the Merger, the items of the Company described in section
           381(c) of the Code, subject to the conditions and limitations of
           sections 381, 382, 383 and 384 of the Code, and the regulations
           thereunder; and

    (11)   The basis of Holding common stock will be increased by the amount in
           which Company's tax basis in its assets exceeds the tax basis in its
           liabilities (Regulation

           1.358 - 6(c)(1)).

In rendering this opinion, we have examined the Agreement and such other
documents as we have deemed appropriate.  We have assumed the genuineness of
all signatures, the legal capacity of all natural persons, the authenticity of
all documents submitted to us as originals, the conformity to original
documents of all documents submitted to us as copies, the authenticity of the
originals of such copies, and that the Merger will be consummated pursuant to
the applicable states' laws in the manner set forth in the Agreement.  We have
also assumed that any written representations and covenants of the Company,
Associated and Holding made in connection with rendering our opinion will be
accurate and complete in all respects as of the time they are provided to us
and as of the closing of the Merger.  Any changes in these facts, or in the
accuracy of these assumptions, representations or covenants, would necessitate
reconsideration of our opinion and possibly result in a different conclusion.

Our opinion is limited to those federal income tax issues specifically
considered herein and is addressed to and is only for the benefit of the
Company, Associated and Holding.  The opinion is furnished to you pursuant to
sections 7.02(f) and 7.03(e) of the Agreement and may not be used or relied
upon for any other purpose, and may not be circulated or otherwise referred to
for any other purpose, without our express written consent.


Very truly yours,
