         2.      Preamble.

         F & M and Subsidiary are multi-bank holding companies with
subsidiaries located in Wisconsin.  Subsidiary is a wholly-owned subsidiary of
F & M.  WBC is a one-bank holding company which presently owns 100% of the
issued and outstanding stock of BANK. F & M, Subsidiary and WBC, by their
respective employees and agents have had the opportunity to make such review
and investigation of the other as they deem appropriate and to negotiate the
terms and conditions of this Agreement.  F & M, Subsidiary and WBC each believe
that this transaction is in their best interests and in the best interests of
their shareholders and desire to set forth their agreement and understanding in
this Agreement.

         The parties have considered the proposed merger and believe that a
merger between WBC and Subsidiary will be the best interest of their respective
corporations and shareholders.  The merger of WBC into Subsidiary is intended
to constitute a reorganization





                                      -2-
<PAGE>   3

within the meaning of Sections 368(a)(1)(A) and 368(a)(2)(E) of the Internal
Revenue Code of 1986, as amended.

         In consideration of the foregoing and the terms, conditions and
covenants of this Agreement and in reliance on the warranties and
representations contained herein, the parties adopt this Plan and Agreement of
Merger and Reorganization and agree as follows:

3.       Merger of WBC into Subsidiary.

         3.1     Surviving Corporation.  At the Effective Time of the merger,
WBC shall be merged into Subsidiary in accordance with the laws of the State of
Wisconsin.  Subsidiary will be the surviving corporation and the separate
corporate existence, identity and organization of WBC, except as specifically
provided by law and this Agreement, shall cease.  As the surviving corporation,
Subsidiary shall succeed to and possess all the assets, properties, powers,
privileges, rights and immunities of WBC and shall be subject to all
liabilities, obligations, limitations and duties of WBC as described in this
Agreement, including but not limited to the liabilities for loans made to WBC
by the WBC Shareholders which will be repaid by Subsidiary on the Closing Date.

         3.2     Subsidiary Stock Subscription.  Subject to fulfilling of the
conditions precedent to the closing of this transaction set forth below, F & M
will transfer to Subsidiary such shares of F & M Common and cash as may be
necessary to effect the merger, as described under paragraph 3.3 below.

         3.3     Exchange of WBC Common.  At the Effective Time, the shares of
the WBC Common shall be converted into shares of F & M Common as follows:

                 (a)      All WBC Shareholders will receive shares of F & M
Common based upon the Exchange Ratio.  The Exchange Ratio shall be calculated
by dividing the F & M Stock Consideration by the number of shares of WBC Common
issued and outstanding as of the Closing Date (excluding any treasury shares).
The Exchange Ratio shall be multiplied by the number of shares of WBC Common
held by each WBC Shareholder on the Closing Date to determine the number of
shares of F & M Common to be issued to that WBC Shareholder.

                 (b)      The F & M Stock Consideration will be Five Hundred
Seventy-five Thousand (575,000) shares of F & M Common, adjusted
proportionately as necessary to reflect any stock dividend declared between the
date of this Agreement and the Closing Date and subject to F & M's right to
terminate under paragraph 3.4.

                 (c)  In the event F & M declares a stock dividend or a stock
split in the form of a stock dividend with respect to F & M Common, the record
date for which is prior to the Closing Date, the F & M Stock Consideration will
be adjusted proportionately to reflect such stock dividend.  For example, if F
& M declared a ten





                                      -3-
<PAGE>   4

percent (10%) stock dividend, the F & M Stock Consideration shall be increased
by ten percent (10%) from 575,000 shares to 632,500 shares.

         3.4     Exchange of WBC Preferred.  At the Effective Time, the
outstanding shares of WBC Preferred shall be converted into cash equal to its
par value of One Hundred and 00/100 Dollars ($100.00) per share plus any
dividends accrued and unpaid since the last dividend payment date, pro rated to
the Closing Date.

         3.5     Right to Terminate. F & M shall have the right to terminate
this Agreement, if any of the following occurs prior to the Closing Date:

                 (a)      WBC  is or  becomes obligated, to increase the number
of outstanding shares of WBC Common as of the Closing Date and the sum of the
actual number of shares of WBC Common outstanding and any additional shares
which WBC is obligated to issue as of the Closing Date is not used to determine
the Exchange Ratio.

                 (b)      The expenses of this transaction [as set forth in
paragraph 4.4(d)] exceed the limit established in paragraph 4.4(d).

                 (c)      The actual earnings of BANK, determined in accordance
with generally accepted accounting principles, applied on a consistent basis,
net of tax effect (the "Actual Earnings") as of the end of the month
immediately preceding the Closing Date are less than the amount corresponding
to such month end as shown on the attached Schedule A (the "Minimum Earnings").
The expenses of this transaction [as defined in paragraph 4.4(d)] and any
expense necessary to increase the BANK's reserve for loan and lease losses
shall not be considered in determining BANK's Actual Earnings or Minimum
Earnings under this paragraph.

         3.6     Articles of Incorporation.  The Articles of Incorporation of
Subsidiary in effect immediately prior to the Effective Time of the merger
shall continue in full force and effect as the Articles of Incorporation of the
surviving corporation.

         3.7     Bylaws.  The Bylaws of Subsidiary in effect immediately prior
to the Effective Time of the merger, shall continue in full force and effect as
the bylaws of the surviving corporation.

         3.8     Officers, Directors and Employees.  The present members of
BANK's Board of Directors will be retained by F & M as directors of the
surviving corporation provided that continued membership on the board is
consistent with safe and sound banking practices and is in the best interest of
F & M and BANK.  Retirement from the Board of Directors will occur at age
seventy (70), as provided by F & M policy, provided that any director who is
age seventy (70) at the time of consummation of the acquisition of BANK by F &
M may remain a director until the earlier of either two (2) years from





                                      -4-
<PAGE>   5

the Effective Date or the 1999 annual shareholders' meeting of the surviving
corporation.  F & M contemplates that BANK's current employees will continue to
be responsible for the BANK's operations in general, subject to review and
supervision by F & M, as determined by F & M to be consistent with safe and
sound banking practices and the best interest of F & M and BANK.  The salaries
and benefits to be offered will be consistent with those currently received by
the employees of F & M or its subsidiary banks holding similar positions.
Years of service with BANK shall, to the extent permitted by applicable law, be
counted as years of service with F & M and the surviving corporation.  In the
unlikely event positions with the BANK are eliminated as a result of the
transaction contemplated by this Agreement, the employees affected by such
action will be covered by F & M's severance plan, applicable to their position
at the time the positions are eliminated, based upon their years of service
with BANK.  The officers and directors of BANK at the Effective Time of the
merger shall remain as the officers and directors of the surviving corporation,
provided, however, and except as expressly set forth above, that nothing in
this paragraph shall create any rights in favor of such officers and directors
to continued status as such following the consummation of the merger.

4.       Representations and Warranties of WBC.  WBC, by its duly authorized
officers, directors or other agents makes the following representations and
warranties to F & M each of which is true and correct as of the date hereof,
and shall remain true and correct to and including the Closing Date, and shall
be unaffected by any investigation heretofore or hereafter made by or any

To the best knowledge of WBC's officers and directors, after due and diligent
inquiry all of WBC's Financial Statements are true and correct in all material
respects and present an accurate and complete disclosure of the financial
condition of WBC as of their respective dates, and the earnings for the periods
covered, all determined in accordance with generally accepted accounting
principles, applied on a consistent basis.

                 (b)      To the best of BANK's knowledge, after due and
diligent inquiry, BANK does not have any loans presently outstanding which are
not in compliance with the requirements of federal or state banking laws or
regulations, except as set forth in Exhibit 4.4(b), which present any greater
than normal risk of collection or which were not made in the normal course of
business.  BANK's last examination by the Federal Deposit Insurance Corporation
("FDIC") was as of June 12, 1995, and by the State of Wisconsin Department of
Financial Institutions, Division of Banking Commissioner ("Division") June 27,
1996.   WBC's last examination by the Federal Reserve Bank of Chicago (the

which are or may be subject to adverse classification except as set forth in
BANK's watch list as of January 31, 1997, a copy of which is attached hereto as
Exhibit 4.4(b), or of any adverse regulatory





                                      -7-
<PAGE>   8

action or proceeding against BANK, WBC or their respective officers, directors,

                 (c)      WBC and BANK have good marketable title to all of
their assets, business and properties including, without limitation, all such
properties reflected in the WBC's Financial Statements as of December 31, 1995,
free and clear of any mortgage, lien, pledge, security interest, assessment,
levy, charge, claim or other encumbrance, except for real estate and personal
property taxes for 1996 which are not yet due.  WBC and BANK do not have any
notice of any special assessment which will be levied or assessed against any
real property owned or leased by them.  To the best knowledge of WBC's officers
and directors, after due and diligent inquiry all real property owned, operated
and leased by WBC and BANK is in full compliance in all material respects with
all applicable federal, state and local statutes and regulations including, but
not limited to, any building codes, safety codes, OSHA regulations,
environmental laws and regulations, the Americans with Disabilities Act, zoning

WBC and BANK, or in which they have an interest (excluding interests which
arise in collateral given to secure loans made by BANK or because of a security
interest granted to BANK) or which are in their possession, are in good
operating condition and repair subject only to normal wear and tear.  A
schedule of all real and personal property owned by WBC and BANK is attached as
Exhibit 4.4(c).  If WBC or BANK lease any real or personal property, a separate
schedule clearly identifying such leased property will be included as a part of
Exhibit 4.4(c).  As of the Closing Date, all such property and assets will be
in the condition represented above.

                 (e)      For the period from January 1, 1997 to the Closing
Date, BANK has projected in good faith that its ordinary earnings determined in
accordance with generally accepted accounting principles, applied on a
consistent basis, net of tax effect, shall be as set forth in the attached
Exhibit 4.4(e).  The expenses of this transaction are those incurred by BANK
for legal, tax opinion, accounting and/or auditing or investment banking and/or
brokerage fees or expenses associated with the acquisition of BANK by F & M and
will be reasonable and customary and will not in any event exceed Ten Thousand
and 00/100 Dollars ($10,000.00).

                 (f)      For the fiscal year ended December 31, 1996, after
excluding amounts paid for new positions created in 1996, BANK did not increase
the amount of the salary, wages, bonuses or other cash





                                      -8-

                 (q)      Shall not take any action which would be reasonably

reorganization.

paragraph 3.4(b) or BANK's Minimum Earnings under paragraph 3.4(c).

         6.6     Reserves for Loan and Lease Losses.  BANK shall take such
action as may be necessary to maintain its reserve for loan and lease losses at

shall have the prior written consent of F & M to establish a lower reserve for
loan and lease losses.

follows:

                 (a)       As promptly as practicable after the execution of
