                  WHEREAS, Dairy State is a bank holding company, the
wholly-owned subsidiary of which is Dairy State Bank, a Wisconsin banking
corporation located in Plymouth, Wisconsin (the "Bank"); and

                  WHEREAS, the Bank has only one wholly-owned subsidiary, Dairy

Investments are sometimes individually referred to herein as a "Subsidiary" and
collectively as the "Subsidiaries;" and

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

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

                  WHEREAS, the Board of Directors of Dairy State believes the
Merger will benefit the shareholders and the employees of Dairy State and the
Subsidiaries; and

                  WHEREAS, the respective Boards of Directors of FMB, Interim

of Dairy State's Common Stock for cash pursuant 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 Dairy State has, subject to
its fiduciary duties under applicable law, resolved to recommend approval of the
Merger by the shareholders of Dairy State; and

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

<PAGE>   6


                  NOW, THEREFORE, in consideration of the foregoing and the
mutual covenants and agreements herein contained, and intending to be legally
bound hereby, FMB, Interim and Dairy State 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) Interim shall be merged with and
into Dairy State. As a result of the Merger, the separate corporate existence of
Dairy State shall cease and Interim shall continue as the surviving corporation

                  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 Department of Financial Institutions of the State of
Wisconsin, in such form as required by, and executed in accordance with the
relevant provisions of Wisconsin Law (a) after the satisfaction, or if
permissible, waiver of conditions set forth in Article VII, and (b) as promptly
as possible after 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 Dairy State to vote upon the Merger pursuant to Section
                  6.01; or

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

                  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 Interim and Dairy State shall vest in the Surviving
Corporation, and all debts, liabilities and duties of Interim and Dairy State
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 Dairy State, as
in effect immediately prior to the Effective Time, shall be the Articles of
Incorporation and the Bylaws of the Surviving Corporation.

                  SECTION 10.5 Directors and Officers. The directors of Interim

the Surviving Corporation, in each case until their respective successors are

                  SECTION 1.06 Conversion of Securities. At the Effective Time,
by virtue of the Merger and without any action on the part of FMB, Interim,
Dairy State, or the holders of any of the following securities:

                           (a) each of the 2,900 shares of common stock, par
                  value $50 per share of Dairy State (the "Dairy State Common
                  Stock"), issued and outstanding immediately prior to the
                  Effective Time (other than 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 cash at the rate
                  of $4,662.33 per share, all in accordance with the terms and
                  conditions hereof and of the Plan of Merger dated as of the
                  date hereof and in the form attached hereto as Exhibit B (the
                  "Plan of Merger"). As of the Effective Time, all shares of
                  Dairy State 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 of Dairy State Common Stock shall thereafter
                  represent the right to receive cash in the amount into which
                  such Dairy State Common Stock is convertible. Certificates
                  previously representing shares of Dairy State Common Stock
                  shall be exchanged for the cash representing the consideration
                  therefor upon the surrender of such certificates in accordance
                  with the provisions of Section 1.07, without interest.

                           (b) each share of Dairy State Common Stock held in
                  the treasury of Dairy State, each share of 5% preferred stock,
                  par value $250 per share of Dairy State (the "Dairy State
                  Preferred Stock"), and each share of Dairy State Common Stock
                  owned by FMB or any direct or indirect wholly owned subsidiary
                  of FMB immediately prior to the Effective Time shall be
                  cancelled and extinguished without any conversion thereof and
                  no payment shall

                                       3
<PAGE>   8


                  be made with respect thereto.

                           (c) each share of Dairy State 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 cash in the amount
                  designated hereunder (all such shares of Dairy State Common
                  Stock are hereinafter called "Dissenting Shares of Dairy State
                  Common Stock"). Dairy State shall give FMB prompt notice upon
                  receipt by Dairy State of any written notice from any such
                  shareholder of Dairy State ("Dissenting Shareholder"). Dairy
                  State agrees that prior to the Effective Time, it will not,
                  except with prior written consent of FMB, 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 Dairy State Common Stock shall receive
                  payment therefor from FMB (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
                  Dairy State Common Stock, his or her shares shall be thereupon
                  converted into cash in accordance with the provisions of
                  Section 1.06(a).

                  SECTION 1.07      Payment.

                           (a) Payment Agent. As of the Effective Time, FMB
                  shall deposit, or shall cause to be deposited, with First
                  National Bank in Manitowoc (the "Payment Agent"), and such
                  deposit shall be solely for the benefit of the holders of
                  shares of Dairy State Common Stock, for payment in accordance
                  with this Article I through the Payment Agent, cash in the
                  aggregate amount of $13,520,757 (hereinafter referred to as
                  the "Payment Fund") issuable pursuant to Section 1.06 in
                  payment for outstanding shares of Dairy State Common Stock.

                           (b) Payment Procedures. Ten business days prior to
                  the Effective Time, the Payment Agent shall mail or personally
                  deliver to each holder of record (or his or her
                  attorney-in-fact) of a certificate or certificates which at
                  the time of such mailing represented outstanding shares of
                  Dairy State Common Stock (the "Certificates"), whose shares of
                  Dairy State Common Stock were converted into the right to
                  receive cash pursuant to Section 1.06, (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 Payment
                  Agent and shall be in such form and have such other provisions
                  as FMB may reasonably specify) ("Letter of Transmittal") and

                  Payment Agent shall mail or personally deliver to each holder
                  of a Certificate or Certificates who was not previously sent a
                  Letter of Transmittal, (i) a Letter of Transmittal and (ii)
                  instructions for use in effecting the surrender of the
                  Certificates in exchange for the cash consideration. Upon
                  surrender of a Certificate for cancellation to the Payment
                  Agent, together with such letter of transmittal, duly
                  executed, the holder of such Certificate shall be entitled to
                  receive in exchange therefor cash representing the
                  consideration for such shares of Dairy State Common Stock as
                  provided in Section 1.06(a), and the Certificate so

                  Common Stock which are not registered in the transfer records
                  of Dairy State, cash representing the proper consideration may
                  be issued to a transferee if the Certificate representing such
                  shares of Dairy State Common Stock is presented to the Payment
                  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 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 cash upon such surrender as contemplated
                  by Section 1.06(a).

                           (c) Distributions with Respect to Unexchanged shares
                  of Dairy State Common Stock. No cash payment for shares shall
                  be paid to any holder of any unsurrendered Certificates
                  pursuant to Section 1.06(a), 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, without
                  interest, the amount of any cash to which such holder is
                  entitled pursuant to Section 1.06(a).

                           (d) No Further Rights in the shares of Dairy State
                  Common Stock. The cash paid pursuant to Section 1.06(a) shall
                  be deemed to have been issued in full satisfaction of all
                  rights pertaining to such shares of Dairy State Common Stock.

                           (e) Termination of Payment Fund. Any portion of the
                  Payment Fund which remains undistributed to the shareholders
                  of Dairy State for six months after the Effective Time shall
                  be delivered to FMB, upon demand, and any shareholders of
                  Dairy State who have not theretofore complied with this
                  Article I shall thereafter look only to FMB for payment of
                  their claim for cash as provided in Section 1.06(a).

                           (f) No Liability. Neither FMB, Interim or Dairy State
                  shall be liable to any holder of shares of Dairy State Common
                  Stock for any such shares of Dairy State Common Stock or cash
                  delivered to a public official pursuant to

                           (g) Withholding Rights. FMB shall be entitled to
                  deduct and withhold from any cash consideration payable
                  pursuant to this Agreement to any holder of shares of Dairy
                  State Common Stock such amounts as FMB 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. To the
                  extent that amounts are so withheld by FMB, such withheld
                  amounts shall be treated for all purposes of this Agreement as
                  having been paid to the holder of the shares of Dairy State
                  Common Stock in respect of which such deduction and
                  withholding was made by FMB.

                  SECTION 1.08 Stock Transfer Books. At the Effective Time, the
stock transfer books of Dairy State shall be closed and there shall be no
further registration of transfers of shares of Dairy State Common Stock
thereafter on the records of Dairy State. From and after the Effective Time, the
holders of certificates evidencing ownership of shares of Dairy State Common
Stock outstanding immediately prior to the Effective Time shall cease to have
any rights with respect to such shares of Dairy State Common Stock except as
otherwise provided herein or by law. On or after the Effective Time, any
Certificates presented to the Payment Agent or FMB for any reason shall be
converted into cash in accordance with Section 1.06(a).

                  Division of Banking of the Wisconsin Department of Financial
                  Institutions and any other applicable federal or state
                  securities or banking authorities (all such reports and
                  statements are collectively referred to as the "Dairy State
                  Reports"). Dairy State Reports, including all Dairy State
                  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
                  Dairy State (including, in each case, any related notes
                  thereto) delivered to FMB whether or not contained in Dairy
                  State Reports (the "Financial Statements"), including, but not
                  limited to, any Dairy State Reports filed since the date of
                  this Agreement and prior to or at 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 Dairy State 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




                                       10

                  subject to normal and recurring yearend 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 Dairy State and the Subsidiaries
                  as of December 31, 1998, including all notes thereto (the
                  "Dairy State Balance Sheet"), neither Dairy State 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, 1998, that would not, individually or in the
                  aggregate have a Material Adverse Effect on Dairy State 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

course and in a manner consistent with past practice and, since December 31,
1998, there has not been (a) any change in the financial condition, results of
operations or business of Dairy State or the Subsidiaries having a Material
Adverse Effect on Dairy State or the Subsidiaries, taken as a whole, (b) any
damage, destruction or loss with respect to any assets of Dairy State or the
Subsidiaries having a Material Adverse Effect on Dairy State or the
Subsidiaries, taken as a whole, (c) any change by Dairy State or the
Subsidiaries in their accounting methods, principles or practices, except for
compliance with any applicable new requirements of the Financial Accounting

                                       11

by, any federal or state banking authority or other governmental entity, or any
judgment, order, writ, injunction, decree or award of any 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, investigation, or controversy affecting

                  defined in section 3(2) of the Employee Retirement Income

                  contributed to by Dairy State 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 Dairy State 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.

                  welfare benefit plan previously maintained, sponsored or
                  contributed to by Dairy State or any Subsidiary which, as of
                  the Effective Time, has not distributed all of its assets
                  and/or satisfied all of its obligations.

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

                           (d) Dairy State Disclosure Schedule at Section 2.10
                  lists all plans or programs to provide material fringe
                  benefits to Dairy State'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) Dairy State has not communicated to employees any
                  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 Dairy State's or




                                       12
<PAGE>   17

                   any Subsidiary's employees, except changes required by law.
                   Neither Dairy State 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 or Welfare Plan documents provided to FMB.

                           (f) Neither Dairy State nor any Subsidiary has been
                  obligated to contribute to any multi-employer plan within the
                  meaning of ERISA section 3(37) within the six (6) years
                  preceding the date of this Agreement.

                           (g) To Dairy State'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 Dairy State'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, other than routine claims for benefits
                  thereunder. 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 Dairy State'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.

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

                           (i) Dairy State has furnished to FMB copies of the
                  governing investment prospectuses and 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





                                       13
<PAGE>   18

                  complete.

                           (j) To Dairy State's knowledge, 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, for which exemption exists.

                           (k) Dairy State has no knowledge of the occurrence of
                  any event with respect to any Pension Plan which could result
                  in a liability of Dairy State, any Subsidiary or any member of
                  Dairy State's controlled group (within the meaning of Code
                  section 414(b), (c) or (n)) 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.

                           (l) No Welfare Plan or Fringe Benefit Plan provides
                  any form of postretirement health benefits to retired
                  employees of Dairy State 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 Dairy State's Disclosure Schedule at Section 2.11, neither Dairy
State nor any Subsidiary is a party to or bound by (a) any employment or
consulting contract that is not terminable without penalty by Dairy State or
such Subsidiary on 60 days' or less notice, (b) any contract or commitment for
capital expenditures in excess of $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 Title to Property. Dairy State's Disclosure
Schedule at Section 2.12 correctly identifies all real property owned or leased
by Dairy State and the Subsidiaries. Dairy State 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 Dairy State or the
Subsidiaries, taken as a whole; and all leases pursuant to which Dairy State 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 by Dairy State or any Subsidiary or to the
knowledge of Dairy State, by any other party thereto or any event of default by
Dairy State or any Subsidiary or, to the knowledge of Dairy State by any other
party thereto (or event which with notice or lapse






                                       14
<PAGE>   19

of time, or both, would constitute a material default by Dairy State or any
Subsidiary and in respect of which Dairy State or any Subsidiary has not taken
adequate steps to prevent such a default from occurring). Dairy State'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
Dairy State 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 nonconforming 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 2.13      Compliance with Environmental Laws.

                  has a present right to acquire upon foreclosure and which are
                  owned by customers of the Bank who have received written

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

                           (5) The term "Hazardous Substances" shall mean all

                  the use of Dairy State's Property (as presently conducted and
                  used) in compliance with Environmental Laws are in full force
                  and effect.

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

                           (3) The business of Dairy State and the Subsidiaries
                  and Dairy State's Property have been and are being operated by
                  Dairy State in accordance with all Environmental Laws and
                  Environmental Permits. Neither Dairy State nor any of the
                  Subsidiaries has received any written notice nor does Dairy
                  State or any of the Subsidiaries have knowledge that Dairy
                  State'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 Dairy State's
                  knowledge, threatened.

                           (4) There are no actions pending, or threatened
                  against Dairy State or any of the Subsidiaries (naming Dairy
                  State or any Subsidiary), which in any case assert or allege
                  (i) Dairy State or any Subsidiary (naming Dairy State 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) Dairy State 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 Dairy State's Property
                  or elsewhere; or (iii) Dairy State 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 Dairy State, the
                  Subsidiaries or others. Dairy State, the Subsidiaries and
                  Dairy State's Property are not subject to any judgment,
                  stipulation, order, decree or agreement arising under
                  Environmental Laws.

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




                                       16
<PAGE>   21

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

                  SECTION 2.14 Absence of Agreements. Neither Dairy State 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
Dairy State 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, Dairy State 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 Dairy State 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 2.15 Taxes. During the six year period prior to the
Effective Time, Dairy State and the Subsidiaries have timely filed all Tax
Returns (as defined below) required to be filed by them, and Dairy State 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 Dairy State is
maintaining reservesadequate for their payment. To the best knowledge of Dairy
State, 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 Dairy State's knowledge,
threatening to assert against Dairy State or any Subsidiary any deficiency or
claim for additional Taxes. Neither Dairy State nor any





                                       17
<PAGE>   22

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 Dairy State or any Subsidiary. Neither Dairy State 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 Dairy State or the Subsidiaries, taken as a whole.
The accruals and reserves for taxes reflected in Dairy State's Balance Sheet are
adequate to cover all Taxes accruable by Dairy State 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 Dairy State Disclosure Schedule at Section 2.15, no agreements relating
to allocating or sharing of Taxes exist between Dairy State and the
Subsidiaries.

                  SECTION 2.16 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 Dairy State and the
Subsidiaries have been delivered to FMB. 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 Dairy State,
the insurance policies to which Dairy State or the Subsidiaries are parties are
sufficient for compliance with all material requirements of law and all material
agreements to which Dairy State or the Subsidiaries are parties and will be
maintained by Dairy State and the Subsidiaries until the Effective Time. Neither
Dairy State 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 2.17 Absence of Adverse Agreements. Neither Dairy
State 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 Dairy State or the
Subsidiaries, taken as a whole.

                  SECTION 2.18 Internal Controls and Records. Dairy State 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
lending agreement, collateral document or security which is not fully



                                       18
<PAGE>   23

reflected in the books and records of Dairy State or the Subsidiaries.

                  SECTION 2.19 Loans. Except as disclosed in Dairy State
Disclosure Schedule at Section 2.19, (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 Dairy State or the Subsidiaries or banking
regulators; (b) neither Dairy State 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 Dairy State or any
Subsidiary, or any person, corporation or enterprise controlling, controlled by
or under common control with any of the foregoing; or (c) neither Dairy State
nor any Subsidiary is a party to any written or oral loan agreement, vote or
borrowing arrangement in violation of any law, regulation or rule of any
governmental authority and which violation could have a Material Adverse Effect
on Dairy State or the Subsidiaries, taken as a whole.

                  SECTION 2.20 Labor Matters. Except as will not cause a
Material Adverse Effect to Dairy State or the Subsidiaries, (a) Dairy State and
the Subsidiaries are in compliance with all applicable laws respecting
employment and employment practices, terms and conditions of employment and
wages and hours, and are not engaged in any unfair labor practice; (b) there is
no unfair labor practice complaint against Dairy State or any Subsidiary pending
before the National Labor Relations Board, (c) there is no labor strike,
dispute, slowdown, representation campaign or work stoppage actually pending or
to the knowledge of Dairy State, threatened against or affecting Dairy State or
any Subsidiary; (d) no grievance or arbitration proceeding arising out of or
under collective bargaining agreements is pending and no claim therefor has been
asserted against Dairy State or any Subsidiary; and (e) neither Dairy State nor
any Subsidiary is experiencing any material work stoppage.

                  SECTION 2.21 Brokers. Except as set forth in the Dairy State
Disclosure Statement at Section 2.21, 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 Dairy State or the Subsidiaries.

                  SECTION 2.22 Full Disclosure. No statement contained in any
document, certificate, or other writing furnished or to be furnished by or at
the direction of Dairy State to FMB 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 2.23 Vote Required. The affirmative vote of a majority
of the votes that holders of the outstanding shares of Dairy State's Common
Stock are entitled to cast is the only vote of the holders of any class or
series of Dairy State's capital stock necessary to approve the Merger.

                                   ARTICLE III

                      REPRESENTATIONS AND WARRANTIES OF FMB

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

                  SECTION 3.01      Organization and Qualification. FMB is a
bank holding company duly organized and validly existing under the laws of the
State of Wisconsin and is registered with the Federal Reserve Board as bank
holding company under the BHCA. FMB and Interim 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 "FMB 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 FMB Approvals would not, individually or in the aggregate, have a
Material Adverse Effect on FMB or Interim, taken as a whole. FMB has not
received any notice of proceedings relating to the revocation or modification of
any such FMB Approvals. FMB and Interim 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
good standing that would not, either individually or in the aggregate, have a
Material Adverse Effect on FMB or Interim taken as a whole.

                  SECTION 3.02      Authority. FMB and Interim 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 FMB and
Interim and the consummation by FMB and Interim of the transactions contemplated
hereby have been duly and validly authorized by all necessary corporate action
on the part of FMB and Interim and no other corporate proceedings on the part of
FMB or Interim 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 FMB and Interim and, assuming the due authorization,
execution and delivery by Dairy State, constitutes the legal, valid and binding
obligation of FMB and Interim.

                  SECTION 3.03      No Conflict, Required Filings and Consents.

                            (a) To the best knowledge of FMB, the execution and
                  delivery of this Agreement by FMB and Interim does not, and
                  the performance of this Agreement by FMB and Interim shall
                  not, (i) conflict with or violate the Articles of
                  Incorporation or Bylaws of FMB or Interim, (ii) conflict with
                  or violate any Laws applicable to FMB or Interim 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,




                                       20
<PAGE>   25

                  or give to others any nights 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
                  FMB or Interim pursuant to any note, bond, mortgage,
                  indenture, contract, agreement, lease, license, permit,
                  franchise or other instrument or obligation to which FMB or
                  Interim is a party or by which FMB, Interim 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 FMB or Interim, taken as a whole.

                            (b) To the best knowledge of FMB, the execution and
                  delivery of this Agreement by FMB and Interim do not, and the
                  performance of this Agreement by FMB and Interim shall not,
                  require any consent, approval, authorization or permit of, or
                  filming with or notification to, any governmental or
                  regulatory authority, domestic or foreign, except (i) for
                  applicable requirements of 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 FMB and
                  Interim from performing their obligations under this
                  agreement, and would not have a Material Adverse Effect on FMB
                  or Interim, taken as a whole.

                  SECTION 3.04      Compliance, Permits. To the best knowledge
of FMB, neither FMB nor Interim is in conflict with, or in default or violation
of (a) any Law applicable to FMB or Interim 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 FMB
or Interim is a party or by which FMB or Interim 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
FMB or Interim, taken as a whole.

                  SECTION 3.05      Securities Reports, Financial Statements.

                            (a) As of the date of this Agreement, FMB has
                  delivered to Dairy State in the form filed with the SEC its
                  Annual Report on Form 10K for the fiscal years ended December
                  31, 1998, (the "FMB SEC Report"). The SEC Reports, including
                  all FMB SEC 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 light of the
                  circumstances under which they were made, not misleading.

                            (b) The consolidated financial statements
                  (including, in each case,





                                       21
<PAGE>   26
                  any related notes thereto) contained in the FMB SEC Report,
                  including any FMB SEC Reports filed since the date of this
                  Agreement and prior to or on the Effective Time, have been or
                  will be 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 FMB 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 yearend 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 FMB and its subsidiaries as of
                  December 31, 1998, including all notes thereto (the "FMB
                  Balance Sheet"), neither FMB 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 for liabilities or obligations incurred in
                  the ordinary course of business since December 31, 1998, which
                  would not, individually or in the aggregate, have a Material
                  Adverse Effect on FMB or its subsidiaries, taken as a whole.

                  SECTION 3.06 Absence of Certain Changes or Events. Since
December 31, 1998, to the date of this Agreement, FMB and its subsidiaries have
conducted their businesses only in the ordinary course and in a manner
consistent with past practice and, since December 31, 1998, there has not been
(a) any change in the financial condition, results of operations or business of
FMB or its subsidiaries having a Material Adverse Effect on FMB 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 FMB or its subsidiaries
having a Material Adverse Effect on FMB or its subsidiaries, taken as a whole,
(c) any change by FMB in its accounting methods, principles or practices, (d)
any revaluation by FMB of any of its material assets in any material respect, or
(e) to the date of this Agreement, any entry by FMB or any of its subsidiaries
into any commitment or transactions material to FMB or its subsidiaries, taken
as a whole.

                  SECTION 3.07 Absence of Litigation. Except as disclosed in the
FMB Disclosure Schedule at Section 3.07 and in the FMB 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 FMB
or any of FMB's subsidiaries pending or, to the knowledge of FMB, 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 FMB 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 FMB
or any of FMB's subsidiaries as a





                                       22
<PAGE>   27

result of an examination by any bank regulatory authority.

                  SECTION 3.08 Absence of Agreements. Neither FMB nor Interim 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 the Subsidiaries, whether prior to or subsequent to the
                  date of this Agreement, shall be kept confidential by the
                  representatives of FMB (and shall be used by them only in

                  Time.

                            (c) Consents Obtained. All material consents,

                  connection with the Merger or (ii) seeking to restrain,
                  prohibit or limit the exercise of full rights of ownership or
                  operation by FMB or its subsidiaries of all or any portion of
                  the business or assets of Dairy State or any of the
                  Subsidiaries, which in either case is reasonably likely to
                  have a Material Adverse Effect on either Dairy State or the
                  Subsidiaries, taken as a whole, or FMB or its subsidiaries,
                  taken as a whole.

                            (e) Opinion of Counsel. FMB shall have received from

                  Lardner or other independent counsel for Dairy State
                  reasonably satisfactory to FMB, an opinion dated the Effective
                  Time, in form and substance reasonably satisfactory to FMB,
                  covering the matters set forth in Exhibit C hereto, which
                  opinion shall be based on such assumptions and containing such
                  qualifications and limitations as are appropriate and

                            (g) Burdensome Condition. There shall not be any
                  action taken, or any statute, rule, regulation or order
                  enacted, entered, enforced or deemed applicable to the Merger,
                  by any federal or state governmental entity which, in
                  connection with the grant of any regulatory approval, imposes
                  any condition or restriction upon Dairy State or FMB 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.

                            (h) Environmental Report. FMB shall have received
                  from its Environmental Consultant a written environmental

                  all Environmental Laws;

                                     ii)  no capital improvements should be
                  reasonably required to maintain compliance with all
                  Environmental Laws; and

                                     iii) there are no material contingent
                  liabilities affecting Dairy State's Property arising under
                  Environmental Laws or under Environmental Permits; or Dairy
                  State shall have complied with all of its obligations under
                  Section 6.05.

                            (i) Equity. Dairy State's consolidated equity as of
                  the Effective Time shall be not less than $5,660,750.00

                  reserve (net tax effect) required to meet the condition of
                  Section 7.02(k) compared to the covenant of Section 4.01(g)).

                  Agreement shall be complete and correct in all material
                  respects (except that where any statement in a representation
                  or warranty expressly includes a statement of materiality,
                  such statement shall be true and correct in all respects) as
                  of the Effective Time as though made on and as of the
                  Effective Time with the same force and effect as if made on

                  on such assumptions and contain such qualifications and
                  limitations as are appropriate and reasonably satisfactory to
                  Dairy State.

<PAGE>   39

                                     ii) by Dairy State or FMB (A) if there has
                  been a breach in any material respect (except that where any
                  statement in a representation or warranty expressly includes a
                  standard of materiality, such statement shall have been
                  breached in any respect) of any representation, warranty,
                  covenant or agreement on the part of Dairy State, on the one
                  hand, or FMB, on the other hand, respectively, set forth in
                  this Agreement, or (B) if any representation or warranty of
                  Dairy State, on the one hand, or FMB, on the other hand,
                  respectively, shall be discovered to have become untrue in any
                  material respect (except that where any statement in a
                  representation or warranty expressly includes a standard of
                  materiality, such statement shall have become untrue `in any
                  respect), in either case which breach or other condition has
                  not been cured within 10 business days following receipt by
                  the non-terminating party of notice of such breach or other
                  condition; provided, however, this Agreement may not be
                  terminated pursuant to this clause (ii) by the breaching party
                  or party making any representation or warranty which shall
                  have become untrue in any material respect;

                                    iii) by either FMB or Dairy State if any
                  permanent injunction preventing the consummation of the Merger
                  shall have become final and nonappealable,

                                     iv) by either FMB or Dairy State if the
                  Merger shall not have been consummated before April 30, 2000,
                  for a reason other than the failure of the terminating party
                  to comply with its obligations under this Agreement;,

                                      v) by either FMB or Dairy State if the
                  Federal Reserve Board or the Division of Banking of the
                  Wisconsin Department of Financial Institutions has denied
                  approval of the Merger and neither FMB nor Dairy State has,
                  within thirty (30) days after the entry of such order denying
                  approval, filed a petition seeking review of such order as
                  provided by applicable law;

                                     vi) by FMB if Dairy State fails to perform
                  all of its obligations under Section 6.05;

                                    vii) by FMB if all of the conditions set
                  forth in Section 7.02 are not satisfied on or before April 30,
                  2000;

                                   viii) by Dairy State if all of the
                  conditions set forth in Section 7.03 are not satisfied on or
                  before April 30, 2000; and

                                     ix) by either FMB or Dairy State if all of
                  the conditions set forth in Section 7.01 are not satisfied on
                  or before April 30, 2000.

                                      x) by either FMB or Dairy State if the
                  Merger shall not have been consumated by July 31, 2000
                  regardless of fault.

                            (b) In the event of termination and abandonment by
                  any party as provided above, written notice shall forthwith be
                  given to the other parties, which notice shall specifically
                  describe the basis for such termination.

                  SECTION 8.02      Effect of Termination.

                            (a) If the Merger is not consummated as the result
                  of termination of this Agreement caused otherwise than by
                  breach of a party hereto, Dairy State and FMB each shall pay
                  its own Expenses (as defined in Section 4.04 above) and this
                  Agreement shall immediately terminate, except as set forth in
                  Section 9.01 hereof, and neither Dairy State nor FMB shall
                  have any liability under this Agreement for damages or
                  otherwise.

                            (b) If termination of this Agreement shall have been
                  caused by breach of this Agreement by any party hereto, then,
                  in addition to other 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,
after approval of the Merger by the shareholders of Dairy State, no amendment
may be made which would reduce the amount or change the type of consideration
into which each share of Dairy State Common Stock shall be converted pursuant to
this Agreement upon consummation of the Merger. This Agreement may not be
amended except by an instrument in writing signed by the parties hereto.

                  SECTION 8.04 Waiver. At any time prior to the Effective Time,
any party hereto may (a) extend the time for the performance of any of the
obligations or other acts of the other party hereto, (b) waive any inaccuracies
in the representations and warranties contained herein or in any document
delivered pursuant hereto and (c) waive compliance with any of the agreements or
conditions contained herein. Any such extension or waiver shall be valid if set
forth in an instrument in writing signed by the party or parties to be bound
thereby.

indefinitely.

Disclosure Schedules shall not vary, change or alter the literal meaning of the
