Item 1.           Changes in Control of Registrant.

         On May 14, 1997, First Financial  Corporation (the "Company") announced
that it had entered into an Agreement and Plan of Merger (the "Agreement") among
Associated  Banc-Corp  ("Associated"),  a wholly-owned  subsidiary of Associated
("Merger  Sub"),  and the Company.  Pursuant to the Agreement,  the Company will
merge with  Merger Sub in a  stock-for-stock  exchange  (the  "Merger")  and the
Company will continue as the surviving  corporation of the Merger. The Merger is
subject  to  approval  of  Company  and  Associated   shareholders,   regulatory
authorities and other customary closing conditions.

         In connection  with the Agreement,  Associated and the Company  entered
into two,  separate  option  agreements  pursuant to which the  Company  granted
Associated  an option,  and  Associated  granted  the  Company  an option,  each
exercisable  under  certain  circumstances,  to purchase an aggregate  number of
newly-issued  shares of common stock equal to 19.9% of the outstanding shares of
the other company.

         The  Agreement  (including  exhibits  thereto)  is  attached  hereto as
Exhibit  2.1  and is  incorporated  by  reference  herein.  Each  of the  option
agreements is attached hereto as Exhibit 2.2 and 2.3, respectively,  and each is
incorporated by reference herein.  The Company issued a press release on May 14,
1997 describing the signing of the Agreement with Associated. Such press release

the respective  Boards of Directors of  Associated,  Merger Sub and FFC have (i)

                  WHEREAS, as a condition and inducement to FFC's willingness to

                  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) Merger Sub shall be merged with
and into FFC. As a result of the Merger,  the  separate  corporate  existence of
Merger Sub shall cease and FFC shall  continue as the surviving  corporation  of
the Merger (the  "Surviving  Corporation").  Associated may at any time elect to
modify the structure of the Merger contemplated by this Agreement so long as (i)
there  are no  material  adverse  federal  income  tax  consequences  to the FFC
shareholders as a result of such modification, (ii) the consideration to be paid
to the FFC  shareholders  under this Agreement is not thereby changed or reduced
in amount,  and (iii) such  modification  will not be reasonably likely to delay
materially or jeopardize receipt of any required  regulatory  approvals.  In the
event that Associated elects to change the structure of the Merger,  the parties
agree to modify this Agreement and the various  exhibits  hereto to reflect such
revised structure.

                  SECTION  1.02.  Effective  Time.  Within three  business  days
following  the  last  to  occur  of (i)  receipt  of the  shareholder  approvals
contemplated  at  Section  6.01(b),  (ii)  receipt  of the  required  regulatory
approvals  contemplated  at Section  6.01(c) and  expiration  of any  applicable
waiting periods required  thereby and (iii)  satisfaction of any other condition
to closing set forth in Article VI, or on such other date as the parties  hereto
may agree, 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 required by, and executed in accordance with
the relevant provisions of Wisconsin Law (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.  (a) Legal Effect. 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 Merger Sub and
FFC shall vest in the  Surviving  Corporation,  and all debts,  liabilities  and
duties of Merger Sub and FFC shall become the debts,  liabilities  and duties of
the Surviving Corporation.

                  (b)  Post-Merger  Operations.  Upon the  Merger,  the  parties
intend that the  headquarters  office of  Associated  will remain  designated as
Green Bay, Wisconsin. It is further anticipated that Associated and FFC Bank (as
defined in Section  2.01(d))(or  any  successor to the  operations  of FFC Bank)
will, for the foreseeable  future,  maintain  significant  operations in each of
Green Bay and Stevens Point, Wisconsin.

Effective  Time, the Articles of  Incorporation  and the Bylaws of Merger Sub in
effect  immediately  prior  to the  Effective  Time  shall  be the  Articles  of
Incorporation and Bylaws of the Surviving Corporation following the Merger until
otherwise amended or repealed.

                  SECTION  1.05.  Directors  and  Officers  of Merger  Sub.  The
directors of Merger Sub  immediately  prior to the  Effective  Time shall be the
initial  directors  of  the  Surviving  Corporation,  each  to  hold  office  in
accordance  with the  Articles  of  Incorporation  and  Bylaws of the  Surviving
Corporation,  and the officers of FFC  immediately  prior to the Effective  Time
shall be the initial officers of the Surviving  Corporation,  in each case until
their respective successors are duly elected or appointed and qualified.

                  SECTION 1.06.  Representation on Associated Board.  Associated
shall take all necessary  actions so that as of the Effective Time, the Board of
Directors  of  Associated  shall  consist  of a  total  of  fourteen  Directors,
consisting of (i) seven individuals,  including Harry B. Conlon, the Chairman of
the Board of  Associated,  who are currently  Directors of Associated  and, (ii)
seven  individuals,  including  John C. Seramur,  to be selected by the Board of
Directors  of FFC  (subject  to  the  approval  of the  Board  of  Directors  of
Associated,  such  approval not to be  unreasonably  withheld)  from the current
Board of Directors of FFC. The Board of  Associated  shall be divided into three
classes;  two of which classes shall be of five persons (one of which shall have

other of which shall have two current  directors of Associated and three current
directors  of FFC) and one class of four  persons (two of which shall be current
directors of Associated and the other two of which shall be current directors of

                  SECTION 1.07. Conversion of Securities. At the Effective Time,

                                        4


                  (a) Each share of FFC common stock,  par value $1.00 per share
         ("FFC  Common  Stock")  (all such  shares  of FFC  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 1.07(b)) shall be converted,
         in accordance  with Section  1.08,  into the right to receive .765 (the
         "Exchange  Ratio") shares of Associated  common stock,  par value $0.01
         per share  ("Associated  Common Stock").  As of the Effective Time, all
         such Shares 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 Shares are convertible.  Certificates  previously
         representing  Shares 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 1.08,  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 1.08 hereof.

                  (b) Each  Share held in the  treasury  of FFC or by any of FFC
         Subsidiaries  (as  defined  in Section  2.01) and each  Share  owned by
         Associated  or any  direct  or  indirect  wholly  owned  subsidiary  of
         Associated  immediately  prior to the Effective Time (other than Shares
         held, directly or indirectly, by Associated, any Associated Subsidiary,
         FFC or any FFC Subsidiary in trust accounts,  managed  accounts and the
         like or otherwise  held in a fiduciary or custodial  capacity  that are
         beneficially owned by third parties and Shares held by Associated,  any
         Associated  Subsidiary,  FFC or any FFC  Subsidiary  in respect of debt
         previously  contracted) shall be cancelled and extinguished without any
         conversion thereof and no payment shall be made with respect thereto.

                  (c) Each share of the common stock,  par value $.01 per share,
         of Merger Sub issued and outstanding immediately prior to the Effective
         Time shall by virtue of this  Agreement  and  without any action on the
         part of the holder thereof,  be converted into and exchangeable for one
         share of the common  stock of the  Surviving  Corporation,  which shall
         thereafter  constitute all of the issued and outstanding  shares of the
         common stock of the Surviving Corporation.

                  SECTION 1.08. Exchange of Certificates. (a) Exchange Agent. As
of the Effective Time, Associated shall deposit, or shall cause to be deposited,
with a bank or trust company  designated by Associated  (the "Exchange  Agent"),
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


<PAGE>


                                        5

with any dividends or  distributions  with respect  thereto,  being  hereinafter
referred  to as the  "Exchange  Fund")  issuable  pursuant  to  Section  1.07 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 1.07 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 and
FFC 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 any  fractional
Shares, 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 FFC, 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  as
contemplated by this Section 1.08, 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 1.08(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
1.08(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  1.08(e) and the amount of dividends or other  distributions
with a record date after the Effective Time theretofore paid with respect to


<PAGE>


                                        6

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 1.08(e)) shall be deemed to
have been issued in full  satisfaction of all rights  pertaining to such Shares.
In accordance with Wisconsin Law, there shall be no appraisal  rights  available
to holders of FFC Common Stock or Associated Common Stock in connection with the
Merger.

                  (e) No  Fractional  Shares.  Notwithstanding  anything  to the
contrary  contained  herein,  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 (i) 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 to receive  pursuant to Section 1.07
hereof by (ii) the closing sale price of a share of the Associated  Common Stock
on the Nasdaq National Market on the trading day immediately  preceding the date
of the Effective Time as reported by the Wall Street Journal.

                  (f)  Termination of Exchange Fund. Any portion of the Exchange
Fund which remains  undistributed  to the  shareholders of FFC for twelve months
after the Effective Time shall be delivered to Associated,  upon demand, and any
shareholders of FFC 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,  Merger Sub or FFC 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 the consideration otherwise 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


<PAGE>


                                        7

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  were made by
Associated.

                  SECTION 1.09. Treatment of Stock Options. (a) At the Effective
Time,  each option granted by FFC to purchase  Shares which is  outstanding  and
unexercised  immediately  prior  thereto  shall be assumed by  Associated.  Such
options  shall  cease  to  represent  a right to  acquire  Shares  and  shall be
converted  automatically  into an option to purchase shares of Associated Common
Stock in an amount and at an exercise price determined as provided below:

                  (i) the  number  of shares of  Associated  Common  Stock to be
         subject to the new option  shall be equal to the  product of the number
         of shares of FFC Common Stock  subject to the  original  option and the
         Exchange  Ratio;  provided  that any  fractional  shares of  Associated
         Common Stock resulting from such  multiplication  shall be rounded down
         to the nearest whole share; and

                  (ii) the exercise  price per share of Associated  Common Stock
         under the new option shall be equal to the exercise  price per share of
         FFC Common  Stock under the  original  option  divided by the  Exchange
         Ratio,  provided  that such  exercise  price shall be rounded up to the
         nearest whole cent.

                  (b) the adjustment provided herein with respect to any options
which are  "incentive  stock  options"  (as  defined in Section 422 of the Code)
shall be and is intended to be effected  in a manner  which is  consistent  with
Section 424(a) of the code. The duration and other terms of the new option shall
be the same as the original  option  except that all  references to FFC shall be
deemed to be references to Associated.

                  (c) At the Effective Time, by virtue of the Merger and without
the need of any further corporate  action,  Associated shall assume the Restated
FFC Corporation Stock Option Plan III and the First Financial  Corporation Stock
Option  Plan I, as amended  (the "FFC Stock  Plans"),  with the result  that all
obligations  of FFC under the FFC Stock  Plans,  including  with  respect to FFC
stock options outstanding at the Effective Time under each FFC Stock Plan, shall
be obligations of Associated following the Effective Time.

                  (d) No later than the Effective Time, Associated shall prepare
and  file  with  the  SEC a  registration  statement  on Form  S-8  (or  another
appropriate  form)  registering  a number of shares of  Associated  Common Stock
equal to the number of shares subject to the adjusted options. Such registration
statement  shall be kept  effective (and the current status of the prospectus or
prospectuses  required  thereby shall be maintained) at least for so long as any
adjusted options may remain outstanding.

                                        8

                  (e)  As  soon  as  practicable   after  the  Effective   Time,
Associated  shall deliver to the holders of options to purchase FFC Common Stock
appropriate  notices  setting forth such holders'  rights  pursuant to FFC Stock
Plans and the  agreements  pursuant to which such options  were issued,  and the
agreements  evidencing  the grant of such options shall be assumed by Associated
and shall  continue in effect on the same terms and  conditions  (subject to the
adjustments required by this Section 1.09 after giving effect to the Merger).

                  SECTION 1.10. Stock Transfer Books. At the Effective Time, the
stock  transfer  books of FFC shall be  closed  and  there  shall be no  further
registration  of transfers of Shares  thereafter on the records of FFC. From and
after the Effective  Time, the holders of certificates  evidencing  ownership of
Shares  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 1.11. 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 or other  capital
stock of Associated in shares of Associated  Common Stock or other capital stock
of Associated or any security  convertible into Associated Common Stock or other
capital  stock  of  Associated  or  shall  combine,  subdivide,   reclassify  or
recapitalize  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  from  such  combination  or  subdivision,  an
appropriate  adjustment  shall be made to the  Exchange  Ratio,  for purposes of
determining  the number of shares of  Associated  Common  Stock into which FFC'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.


                                   ARTICLE II

                      REPRESENTATIONS AND WARRANTIES OF FFC

                  Except as set forth in the  disclosure  schedule  delivered by
FFC to Associated  prior to the execution of this Agreement which shall identify
exceptions  by specific  Section  references;  provided  that  disclosure in one
schedule will be deemed to satisfy disclosure in


<PAGE>


                                        9

another  schedule (the "FFC  Disclosure  Schedule"),  FFC hereby  represents and
warrants to Associated and Merger Sub that:

                  SECTION  2.01.   Organization   and   Qualification   of  FFC;
Subsidiaries.  (a) FFC is a corporation duly organized,  validly existing and in
good standing under the laws of the State of Wisconsin. FFC is a unitary savings
and loan holding company  registered with the Office of Thrift Supervision under
HOLA.

                  (b) Section 2.01 of the FFC  Disclosure  Schedule sets forth a
true and complete list of each of FFC's  subsidiaries  (the "FFC  Subsidiaries")
and the percentage owned by FFC of such equity  securities.  Except as set forth
in Section 2.01 of the FFC  Disclosure  Schedule,  each FFC Subsidiary is wholly
owned,  directly or indirectly,  by FFC.  Except as set forth in Section 2.01 of
the FFC  Disclosure  Schedule,  all  outstanding  shares of capital stock of FFC
Subsidiaries  are  validly  issued,  fully  paid and  nonassessable  (except  as
provided in Section  180.0622(2)(b)  of Wisconsin Law) and are free and clear of
any lien, claim, charge,  options,  encumbrances  agreement,  mortgage,  pledge,
security interest or restriction (each, a "Lien") with respect thereto. Each FFC
Subsidiary is a corporation,  partnership,  savings bank, savings and loan, bank
or trust company duly  incorporated or organized,  validly  existing and in good
standing under the laws of its jurisdiction of incorporation or organization.

                  (c) FFC and each FFC  Subsidiary  has the requisite  corporate
power  and  authority  and  is  in   possession  of  all   franchises,   grants,
authorizations,  licenses, permits, easements, consents, certificates, approvals
and orders ("FFC  Permits")  necessary to own,  lease and operate its properties
and to carry on its business as is now being conducted, except where the failure
to be so  organized,  existing  and in  good  standing  or to have  such  power,
authority and FFC Permits would not,  either  individually  or in the aggregate,
have  a  Material  Adverse  Effect  (as  defined  below)  on  FFC  and  the  FFC
Subsidiaries,  taken as a whole.  FFC has not received any notice of proceedings
relating to the  revocation or  modification  of any FFC Permits  except for any
such revocation or modification  which would not, either  individually or in the
aggregate, have a Material Adverse Effect on FFC and the FFC Subsidiaries, taken
as a whole.  FFC and each FFC  Subsidiary  is duly  qualified  or  licensed as a
foreign  corporation  to  do  business,   and  is  in  good  standing,  in  each
jurisdiction where the character of its properties owned,  leased or operated by
it or the  nature  of its  activities  makes  such  qualification  or  licensing
necessary,  except for such failures to be so duly  qualified or licensed and in
good standing that would not, either  individually  or in the aggregate,  have a
Material Adverse Effect on FFC and the FFC Subsidiaries, taken as a whole.

                  (d) Deposits in First  Financial  Bank, a Federally  chartered
savings bank ("FFC Bank"), are insured by the Savings Association Insurance Fund
to applicable limits.


<PAGE>


                                       10

The form of charter and any applicable  insurance fund for each of the other FFC
Subsidiaries  which is a financial  institution  is set forth in Section 2.01 of
the FFC Disclosure Schedule.

                  (e) Section 2.01 of the FFC  Disclosure  Schedule sets forth a
true,  complete  and correct  list of all  corporations,  partnerships,  limited
liability  companies  or  other   organizations,   whether  an  incorporated  or
unincorporated  organization  (a  "Corporate  Entity")  of which  FFC or any FFC
Subsidiary  holds or beneficially  owns 5% or more of the outstanding  shares of
any class of voting securities,  holds a general  partnership  interest or other
controlling  interest,  holds  or  beneficially  owns  more  than  24.9%  of the
outstanding capital stock (whether voting or nonvoting) and subordinated debt or
is otherwise deemed to be a subsidiary within the meaning of the BHCA.

                    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  (including  intangible
properties),   condition   (financial  or  otherwise),   assets  or  liabilities
(including  contingent  liabilities),  in the aggregate,  or the ability of such
party to consummate the transactions contemplated by this Agreement, except that
a Material  Adverse  Effect shall not be deemed to have  occurred as a result of
any change or effect resulting from a change in law, rule, regulation, generally
accepted accounting principle or regulatory accounting principle,  in each case,
affecting financial institutions or their holding companies generally.

                  SECTION 2.02.  Articles of Incorporation  and Bylaws.  FFC has
heretofore furnished or made available to Associated a complete and correct copy
of the Articles of Incorporation and the Bylaws, as amended or restated,  of FFC
and the FFC Subsidiaries  and such Articles of  Incorporation  and Bylaws of FFC
and the FFC  Subsidiaries  are in full force and effect and  neither FFC nor any
FFC  Subsidiary  is in  violation  of any of the  provisions  of its  respective
Articles of Incorporation or Bylaws.

                  SECTION 2.03.  Capitalization.  (a) Capitalization of FFC. The
authorized  capital stock of FFC consists of (i) 75,000,000 Shares, of which, as

compliance with applicable  securities laws, and (ii) 3,000,000 shares of serial

March 31, 1997, FFC had outstanding 1,266,887 options issued under the FFC Stock
Plans,  992,651 of which were  exercisable.  No options have been granted  since

Other than pursuant to the FFC Stock Option Agreement

of first  refusal,  agreements,  arrangements,  or  commitments of any character
relating to the issued or unissued  capital  stock of FFC or  obligating  FFC to

There are no obligations,  contingent or otherwise, of FFC to repurchase, redeem
or otherwise  acquire any Shares or to provide  funds to or make any  investment
(in the form of a loan,  capital  contribution or otherwise) in any other entity
(including any FFC Subsidiary).

                  (b) Capital Stock of the FFC Subsidiaries. Except as set forth
in  Section  2.03  (b) of the FFC  Disclosure  Schedule  there  are no  options,
warrants or other rights, rights of first refusal,  agreements,  arrangements or
commitments of any character relating to the issued or unissued capital stock of

Incorporation.  (a) FFC has the  requisite  corporate  power  and  authority  to
execute and deliver this Agreement,  to perform its obligations hereunder and to

contemplated  hereby  have been duly and  validly  authorized  by all  necessary
corporate  action on the part of FFC and no other  corporate  proceedings on the
part of FFC are  necessary to authorize  this  Agreement  or to  consummate  the
transactions  contemplated  hereby (other than, with respect to the Merger,  the
approval  of the  plan of  Merger  by the  holders  of  two-thirds  of the  then
outstanding  Shares in  accordance  with  Wisconsin  Law and FFC's  Articles  of
Incorporation and Bylaws,  and the filing and recordation of appropriate  merger
documents  required by Wisconsin  Law). This Agreement has been duly and validly
executed and delivered by FFC and, assuming the due authorization, execution and
delivery by Associated and Merger Sub,  constitutes the legal, valid and binding
obligation  of  FFC  enforceable  in  accordance  with  its  terms,   except  as
enforcement may be limited by bankruptcy,  insolvency and similar laws affecting
creditors' rights and remedies generally and by general principles of equity.

                  (b) The  Board  of  Directors  of FFC has  taken  all  actions
necessary  under  Wisconsin Law and FFC's Articles of  Incorporation,  including
approving the transactions  contemplated herein, to insure that the restrictions
on business combinations set forth in Wisconsin Law and the supermajority voting
requirements  set forth in FFC's  Articles of  Incorporation  do not or will not
apply to this Agreement,  the transactions  contemplated  herein,  the FFC Stock
Option Agreement or the transactions contemplated therein or any

transaction  between  Associated or its affiliates,  on the one hand, and FFC or
its affiliates, on the other hand, following exercise of the FFC Stock Option.

                  SECTION 2.05. No Conflict;  Required Filings and Consents. (a)
Except  as set  forth  in  Section  2.05 of the  FFC  Disclosure  Schedule,  the
execution and delivery of this Agreement by FFC does not, and the performance of
this  Agreement by FFC shall not,  (i) conflict  with or violate the Articles of
Incorporation  or Bylaws of FFC or any FFC  Subsidiary,  (ii)  conflict  with or
violate  any  domestic  (federal,  state or  local)  or  foreign  law,  statute,
ordinance,  rule,  regulation,  order,  judgment decision,  writ,  injunction or
decree  (collectively,  "Laws")  applicable to FFC or any FFC Subsidiary,  or by
which its respective  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  on  any  of the  properties  or  assets  of FFC or any  FFC
Subsidiary pursuant to any note, bond, mortgage, indenture, contract, agreement,
lease, license, permit, franchise or other instrument or obligation to which FFC
or any FFC  Subsidiary  is a party or by which FFC or any FFC  Subsidiary or its
respective properties are bound or affected, except (in the case of clauses (ii)
and (iii) of this Section 2.05(a)) for any such conflicts, violations, breaches,
defaults or other  occurrences  that would not,  either  individually  or in the
aggregate, have a Material Adverse Effect on FFC and the FFC Subsidiaries, taken
as a whole.

                  (b) The execution  and delivery of this  Agreement by FFC does
not,  and the  performance  of this  Agreement  by FFC shall  not,  require  any
consent,  approval,  authorization  or permit of, or filing with or notification
to, any governmental or regulatory authority, domestic or foreign, ("Approvals")
except (i) for the applicable requirements, if any, of (A) the Securities Act of
1933, as amended (the  "Securities  Act"),  (B) the  Securities  Exchange Act of
1934, as amended (the "Exchange Act"), (C) the BHCA, (D) HOLA, (E) the Office of
the Comptroller of the Currency (the "OCC"),  (F) the Federal Deposit  Insurance
Act, as  amended,  and the rules and  regulations  promulgated  thereunder  (the
"FDIA"),  (G) state  securities  or blue sky laws  ("Blue  Sky  Laws"),  (H) the
banking  laws and  regulations  of the State of Wisconsin  (the "WBL"),  (I) the
filing and  recordation of appropriate  merger or other documents as required by
Wisconsin  Law,  (J) the banking laws and  regulations  of the State of Illinois
(the "IBL"),  (K) the Nasdaq Stock Market,  (L) applicable  laws and regulations
relating  to  insurance  business  agencies   ("Insurance  Laws")  and  (M)  any
applicable domestic or foreign industry  self-regulatory  organization  ("SRO"),
and (ii) such  additional  Approvals  the  failure of which to obtain  would not
prevent or delay  consummation  of the  Merger,  or  otherwise  prevent FFC from
performing  its  obligations  under  this  Agreement,   and  would  not,  either
individually or in the aggregate,  have a Material Adverse Effect on FFC and the
FFC Subsidiaries, taken as a whole.

                  SECTION 2.06.  Compliance.  Neither FFC nor any FFC Subsidiary
is in conflict  with, or in default or violation  of, (i) any Law  applicable to
FFC or the FFC Subsidiaries or by which any of their  respective  properties are
bound or  affected,  or (ii) any  note,  bond,  mortgage,  indenture,  contract,
agreement,  lease, license,  permit, franchise or other instrument or obligation
to  which  FFC or any FFC  Subsidiary  is a  party  or by  which  FFC or any FFC
Subsidiary or any of their respective  properties are bound or affected,  except
for  any  such  conflicts,  defaults  or  violations  which  would  not,  either
individually or in the aggregate,  have a Material Adverse Effect on FFC and the
FFC Subsidiaries, taken as a whole.

                  SECTION  2.07.  Securities  and  Banking  Reports;   Financial
Statements.  (a) FFC and the FFC  Subsidiaries  have filed all  material  forms,
reports  registrations,  statements and documents,  together with any amendments
required to be made with respect  thereto  that were  required to be filed since
January 1, 1995 with (i) the Securities and Exchange  Commission (the "SEC") and
(ii)(A)  any SRO,  (B) any  other  federal,  state or  foreign  governmental  or
regulatory  agency  or  authority  (collectively  with  the SEC  and  the  SROs,
"Regulatory  Agencies")  and (C) all other reports and  statements  (the filings
made with the  entities  listed in  subclause  (ii) being  referred to as "Other
Reports")  required to be filed by FFC and any FFC  Subsidiary  since January 1,
1995, and paid all fees and assessments due and payable in connection therewith,
except,  in the case of the Other  Reports,  where  failure  to file such  form,
report,  registration,  statement  or document or pay such fees and  assessments
would not,  either  individually  or in the aggregate,  have a Material  Adverse
Effect on FFC and the FFC  Subsidiaries,  taken as a whole (all such reports and
statements, are collectively referred to as the "FFC Reports"). The FFC Reports,
including all FFC 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  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 any filings with the SEC
since  January 1, 1995 (the "FFC SEC  Reports"),  including  any FFC 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,  or will
fairly present, in all material respects, the consolidated financial position of
FFC  and  the  FFC  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 FFC and the FFC Subsidiaries as of December 31, 1996, including
all notes thereto (the "FFC Balance Sheet"),  neither FFC nor any FFC Subsidiary
has any  liabilities or obligations of any nature  (whether  accrued,  absolute,
contingent or otherwise),  except for (i) liabilities or obligations incurred in
the ordinary course of business since December 31, 1996 and (ii)  liabilities or
obligations  that would not,  either  individually  or in the aggregate,  have a
Material Adverse Effect on FFC and the FFC Subsidiaries, taken as a whole.

                  SECTION 2.08. Absence of Certain Changes or Events. (a) Except
as disclosed in the FFC SEC Reports  filed prior to the date of this  Agreement,
since December 31, 1996, (i) FFC and the FFC  Subsidiaries  have conducted their
businesses  only in the  ordinary  course and in a manner  consistent  with past
practice and (ii) there has been no event which has had, or is reasonably likely
to result in, either individually or in the aggregate, a Material Adverse Effect
on FFC and the FFC Subsidiaries, taken as a whole.

                  SECTION 2.09. Absence of Litigation and Agreements. (a) Except
as disclosed in the FFC SEC Reports filed prior to the date of this Agreement or
set forth in Section 2.09 of the FFC  Disclosure  Schedule,  (i) neither FFC nor
any FFC Subsidiary is subject to any continuing  order of, or written  agreement
or memorandum of understanding with, or continuing investigation by, any federal
or state  savings and loan or bank  regulatory  authority or other  governmental
entity or regulatory authority, or any judgment, order, writ, injunction, decree
or award of any  governmental  entity or  regulatory  authority  or  arbitrator,
including,  without  limitation,  cease-and-desist or other orders which, either
individually or in the aggregate, would have or reasonably be expected to have a
Material Adverse Effect on FFC and the FFC Subsidiaries,  taken as a whole; (ii)
there  is  no  claim  of  any  kind,  action,  suit,   litigation,   proceeding,
arbitration, investigation, or controversy affecting FFC or the FFC Subsidiaries
pending or, to the  knowledge of FFC,  threatened,  except (A) as of the date of
this  Agreement,  for matters which  individually  seek damages not in excess of
$500,000  and (B) as of the Closing (as  defined in Section  8.01),  for matters
which otherwise cannot reasonably be expected to have, either individually or in
the aggregate, a Material Adverse Effect on FFC and the FFC Subsidiaries,  taken
as a whole;  and (iii)  there are not uncured  violations,  or  violations  with
respect  to  which  refunds  or  restitutions  may  be  required,  cited  in any
compliance  report to FFC or the FFC Subsidiaries as a result of the examination
by any bank regulatory authority,  which would have or reasonably be expected to
have, either individually or in the aggregate,  a Material Adverse Effect on FFC
and the FFC Subsidiaries, taken as a whole.

                  (b)  Except as set  forth on the FFC  Disclosure  Schedule  at
Section  2.09,  neither  FFC nor any of the FFC  Subsidiaries  is a party to any
written  agreement  or  memorandum  of  understanding  with,  or  party  to  any
commitment  letter,  board  resolution  submitted to a  regulatory  authority or
similar  undertaking  to, or is  subject to any order or  directive  by, or is a
recipient of any extraordinary supervisory letter from any governmental

                                       15

entity or agency which restricts  materially the conduct of its business,  or in
any manner relates to its capital  adequacy,  its credit or reserve  policies or
its  management  nor has FFC or any  FFC  Subsidiary  (i)  been  advised  by any
governmental entity or agency that it 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 or (ii) have knowledge of any
pending  or  threatened  regulatory  investigation.  Neither  FFC  nor  any  FFC
Subsidiary  is required by Section 32 of the Federal  Deposit  Insurance  Act to
give prior notice to a Federal  banking  agency of the  proposed  addition of an
individual  to its board of directors or the  employment  of an  individual as a
senior executive officer.

                  SECTION 2.10.  Employee Benefit Plans. (a) Except as set forth
in Section 2.10 of the FFC Disclosure  Schedule,  since December 31, 1996, there
has not been any adoption or amendment in any material respect by FFC or any FFC
Subsidiary of any employment,  consulting, termination or severance agreement or
any material bonus, pension,  profit sharing,  deferred compensation,  incentive
compensation,  stock  ownership,  stock purchase,  stock option,  phantom stock,
retirement,  vacation,  severance,  disability, death benefit,  hospitalization,
medical or other plan,  arrangement or understanding  providing  benefits to any
current or former  employee,  officer or director  of FFC or any FFC  Subsidiary
(collectively, such agreements, plans, arrangements and understandings being the
"FFC  Benefit  Plans"),  or any  material  change  in  any  actuarial  or  other
assumption used to calculate funding obligations with respect to any FFC pension
plans,  or any change in the manner in which  contributions  to any FFC  pension
plans are made or the basis on which such contributions are determined.

                  (b) Section 2.10 of the FFC  Disclosure  Schedule sets forth a
list of all FFC Benefit Plans. FFC has delivered or made available to Associated
true and  complete  copies of all FFC Benefit  Plans  together  with all current
related  documents,  including the most recent  summary plan  descriptions,  IRS
determination letters and actuarial reports, if applicable.

                  (c)  (i)  Except  as  disclosed  in  Section  2.10  of the FFC
         Disclosure  Schedule,  with respect to FFC Benefit Plans,  no event has
         occurred and, to the knowledge of FFC, there exists no condition or set
         of  circumstances,  in  connection  with  which  FFC or any of the  FFC
         Subsidiaries could be subject to any liability that individually, or in
         the aggregate,  would have a Material Adverse Effect on FFC and the FFC
         Subsidiaries,  taken as a whole,  under  ERISA,  the Code or any  other
         applicable law.

                  (ii) Each FFC Benefit Plan has been administered in accordance
         with its  terms,  except  for any  failures  so to  administer  any FFC
         Benefit Plan that  individually  or in the aggregate,  would not have a
         Material Adverse Effect on FFC and the FFC


<PAGE>


                                       16

         Subsidiaries,  taken as a whole.  FFC, the FFC Subsidiaries and all FFC
         Benefit  Plans are in  compliance  with the  applicable  provisions  of
         ERISA,  the Code and all  other  applicable  laws and the  terms of all
         applicable collective bargaining agreements, except for any failures to
         be in such compliance that, individually or in the aggregate, would not
         have a Material Adverse Effect on FFC and the FFC  Subsidiaries,  taken
         as a whole.  Each FFC Benefit  Plan that is  intended  to be  qualified
         under  Section  401(a) or 401(k) of the Code has  received a  favorable
         determination  letter  from  the IRS that it is so  qualified  and each
         trust  established  in  connection  with any FFC  Benefit  Plan that is
         intended to be exempt from Federal income taxation under Section 501(a)
         of the Code has received a determination  letter from the IRS that such
         trust is so  exempt.  To the  knowledge  of FFC,  no fact or event  has
         occurred since that date of any determination letter from the IRS which
         is reasonably  likely to affect  adversely the qualified  status of any
         such FFC Benefit Plan or the exempt status of any such trust.

                  (iii) Neither FFC nor any of the FFC Subsidiaries has incurred
         any  liability  under  Title  IV of ERISA  (other  than  liability  for
         premiums to the Pension  Benefit  Guaranty  Corporation  arising in the
         ordinary  course).  No FFC Benefit  Plan has  incurred an  "accumulated
         funding  deficiency"  (within  the  meaning of Section  302 of ERISA or
         Section 412 of the Code)  whether or not waived.  To the  knowledge  of
         FFC,  there are not any facts or  circumstances  that would  materially
         change the  funded  status of any FFC  Benefit  Plan that is a "defined
         benefit"  plan (as defined in Section 3(35) of ERISA) since the date of
         the most recent  actuarial report for such plan. No FFC Benefit Plan is
         a "multiemployer plan" within the meaning of Section 3(37) of ERISA.

                  (iv) Neither FFC nor any of the FFC Subsidiaries is a party to
         any collective  bargaining or other labor union contract  applicable to
         persons  employed  by  FFC  or  any  of  the  FFC  Subsidiaries  and no
         collective  bargaining  agreement is being  negotiated by FFC or any of
         the  FFC  Subsidiaries.  There  is no  labor  dispute,  strike  or work
         stoppage against FFC or any of the FFC Subsidiaries  pending or, to the
         knowledge of FFC,  threatened  which may interfere  with the respective
         business  activities  of FFC or any FFC  Subsidiary,  except where such
         dispute,  strike or work  stoppage  individually  or in the  aggregate,
         would  not  have  a  Material   Adverse  Effect  on  FFC  and  the  FFC
         Subsidiaries,  taken as a whole. As of the date of this  Agreement,  to
         the knowledge of FFC, none of FFC, any of the FFC  Subsidiaries  or any
         of their  respective  representatives  or employees  has  committed any
         unfair  labor  practice  in  connection   with  the  operation  of  the
         respective businesses of FFC or any of the FFC Subsidiaries,  and there
         is no charge or complaint against FFC or any of the FFC Subsidiaries by
         the  National  Labor  Relations  Board or any  comparable  governmental
         agency pending or threatened in writing.

                                       17

                  (v) Except as referenced in this Agreement or  contemplated by
         this  Agreement  and  except  as set forth in  Section  2.10 of the FFC
         Disclosure  Schedule,  no employee of FFC or any FFC Subsidiary will be
         entitled to any additional  benefits or any acceleration of the time of
         payment or  vesting of any  benefits  under any FFC  Benefit  Plan as a
         result of the transactions contemplated by this Agreement or the Option
         Agreements.

                  (vi) No payment  or benefit  will or may be made by FFC or any
         FFC  Subsidiary  with  respect to any employee or any current of former
         director that will be  characterized as an "excess  parachute  payment"
         within the meaning of Section 280G(b) of the Code.

                  SECTION  2.11.  Material  Contracts.  Except  as set  forth in
Section 2.11 of the FFC Disclosure  Schedule,  as of the date of this Agreement,
neither FFC nor any FFC Subsidiary is a party to or bound by (a) any contract or
commitment for capital  expenditures  in excess of $500,000 for any one project,
(b)  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 and calling for aggregate  future  payments of $1,000,000 or more
during the term of such  contract or  commitment,  (c) any  contract  which is a
"material  contract"  (as such term is defined in Item  601(b)(10) of Regulation
S-K of the SEC) that has not been filed or  incorporated by reference in the FFC
SEC  Reports,  (d)  any  contract  which  contains  non-compete  or  exclusivity
provisions or  restrictions  with respect to any business or geographic  area or
(e) any contract which would prohibit or materially  delay the  consummation  of
the  Merger  or any  other  transaction  contemplated  by this  Agreement.  Each
contract, arrangement, commitment or understanding of the type described in this
Section  2.11,  whether or not set forth in Section  2.11 of the FFC  Disclosure
Schedule,  is  referred to herein as a "FFC  Contract".  Neither FFC nor any FFC
Subsidiary  knows  of, or has  received  notice  of,  any  violation  of any FFC
Contract  by any of the other  parties  thereto,  except for  violations  which,
individually or in the aggregate,  would not result in a Material Adverse Effect
on FFC and the FFC Subsidiaries, taken as a whole.

                  SECTION 2.12.  Environmental  Matters. To the knowledge of FFC
neither FFC, any FFC Subsidiary,  nor any properties owned or operated by FFC or
any  FFC  Subsidiary  has  been  or  is in  violation  of or  liable  under  any
Environmental Law, except for such violations or liabilities that,  individually
or in the aggregate, are not reasonably likely to have a Material Adverse Effect
on FFC and the FFC Subsidiaries,  taken as a whole. There are no actions,  suits
or proceedings, or demands, claims, notices or investigations (including without
limitation  notices,   demand  letters  or  requests  of  information  from  any
environmental  agency)  instituted  or  pending,  or to the  knowledge  of  FFC,
threatened,  relating to the liability of FFC or any FFC Subsidiary with respect
to any  properties  owned or  operated  by FFC or any FFC  Subsidiary  under any
Environmental Law, except for liabilities or violations

                                       18

that would not reasonably be expected to have, individually or in the aggregate,
a Material Adverse Effect on FFC and the FFC Subsidiaries, taken as a whole.

                  "Environmental Law" means any applicable federal, state, local
or foreign law, statute,  ordinance,  rule, regulation,  code, license,  permit,
authorization,   approval,   consent  order,  judgment,  decree,  injunction  or
agreement  with  any  regulatory  authority  relating  to  (i)  the  protection,
preservation or restoration of the environment  (including,  without limitation,
air, water vapor,  surface water,  groundwater,  drinking water supply,  surface
soil,  subsurface  soil,  plant and animal life or any other natural  resource),
and/or (ii) the use, storage, recycling, treatment, generation,  transportation,
processing, handling, labeling, production, release or disposal of any substance
presently  listed,  defined,  designated  or  classified  as  hazardous,  toxic,
radioactive  or  dangerous,  or  otherwise  regulated,  whether  by  type  or by
quantity, including any material containing any such substance as a component.

                  SECTION 2.13.  Taxes. (a) Except for such matters as would not
have, individually or in the aggregate, a Material Adverse Effect on FFC and the
FFC Subsidiaries, taken as a whole, (i) FFC and the FFC Subsidiaries have timely
filed or will timely  file all returns and reports  required to be filed by them
with any  taxing  authority  with  respect to Taxes (as  defined  below) for any
period ending on or before the Effective Time, taking into account any extension
of  time  to  file  granted  to or  obtained  on  behalf  of  FFC  and  the  FFC
Subsidiaries,  (ii) all Taxes that are due prior to the Effective Time have been
paid or will be paid (other than Taxes which (1) are not yet  delinquent  or (2)
are being contested in good faith and have not been finally  determined),  (iii)
as of the date hereof,  no deficiency  for any Tax has been asserted or assessed
by a  taxing  authority  against  FFC  or  any of  the  FFC  Subsidiaries  which
deficiency has not been paid other than any deficiency  being  contested in good
faith and (iv) FFC and the FFC Subsidiaries  have provided adequate reserves (in
accordance  with generally  accepted  accounting  principles) in their financial
statements for any Taxes that have not been paid,  whether or not shown as being
due on any returns.  As used in this  Agreement,  "Taxes" shall mean any and all
taxes,  fees,  levies,  duties,  tariffs,  imposts and other charges of any kind
(together with any and all interest, penalties,  additions to tax and additional
amounts  imposed with respect  thereto)  imposed by any  governmental  entity or
taxing authority,  including,  without limitation:  taxes or other charges on or
with respect to income,  franchise,  windfall or other profits,  gross receipts,
property,  sales,  use,  capital stock,  payroll,  employment,  social security,
workers'  compensation,  unemployment  compensation or net worth; taxes or other
charges in the nature of  excise,  withholding,  ad  valorem,  stamp,  transfer,
value-added or gains taxes;  license,  registration and documentation  fees; and
customers' duties, tariffs and similar charges.

                  (b) To the  knowledge of FFC,  there are no material  disputes
pending, or claims asserted in writing for, Taxes or assessments upon FFC or any
of the FFC  Subsidiaries,  nor has FFC or any FFC Subsidiaries been requested in
writing to give any currently  effective  waivers extending the statutory period
of limitation applicable to any federal or state

                                       19

income tax return for any period which disputes,  claims, assessments or waivers
would have,  individually or in the aggregate,  a Material Adverse Effect on FFC
and the FFC Subsidiaries, taken as a whole.

                  (c) There are no Tax liens upon any  property or assets of FFC
or any of the FFC  Subsidiaries  except liens for current  Taxes not yet due and
except  for  liens  which  have not had and are not  reasonably  likely to have,
individually or in the aggregate,  a Material  Adverse Effect on FFC and the FFC
Subsidiaries, taken as a whole.

                  (d)  Neither  FFC  nor any of the FFC  Subsidiaries  has  been
required to include in income any adjustment pursuant to Section 481 of the Code
by reason of a voluntary change in accounting  method initiated by FFC or any of
the  FFC  Subsidiaries,  and the IRS has not  initiated  or  proposed  any  such
adjustment or change in accounting  method,  in either case which  adjustment or
change would have,  individually or in the aggregate,  a Material Adverse Effect
on FFC and the FFC Subsidiaries, taken as a whole.

                  (e) Except as set forth in the financial  statements described
in Section  2.07,  neither FFC nor any the FFC  Subsidiaries  has entered into a
transaction which is being accounted for under the installment method of Section
453 of the Code, which would have,  individually or in the aggregate, a Material
Adverse Effect on FFC, and the FFC Subsidiaries, taken as a whole.

                  SECTION  2.14.  Derivative  Instruments.  All  swap,  forward,
future, option, cap, floor or collar financial contracts, and any other interest
rate protection  contracts  ("Derivative  Instruments")  to which FFC or any FFC
Subsidiary  is a party or to which  any of their  properties  or  assets  may be
subject  were  entered  into in the  ordinary  course of  business  and,  to the
knowledge of FFC, in accordance  with prudent  banking  practice and  applicable
rules,   regulations,   and  policies  of  the  regulatory   agencies  and  with
counterparties  believed to be  financially  responsible at the time and, to the
knowledge of FFC,  are legal,  valid,  and binding  obligations  enforceable  in
accordance with their terms (except as may be limited by bankruptcy, insolvency,
moratorium,  reorganization,  or similar laws  affecting the rights of creditors
generally, and the availability of equitable remedies), and, to the knowledge of
FFC,  are in full  force  and  effect.  FFC and  each  FFC  Subsidiary  has duly
performed  in all  material  respects  all of its  obligations  under  any  such
Derivative  Instruments,  and to the  knowledge  of FFC,  there are no breaches,
violations,  or  defaults  or  allegations  or  assertions  of such by any party
thereunder except for any such breaches,  violations, or defaults or allegations
or assertions which would not, individually or in the aggregate, have a Material
Adverse Effect on FFC and the FFC Subsidiaries, taken as a whole.

                  SECTION 2.15.  Regulatory  Approvals.  FFC is not aware of any
aspect of, or issues  relating to, its or the FFC  Subsidiaries'  operations and
business  that would  prevent  the  condition  of  Closing  set forth in Section
6.01(c) from being satisfied.

                  SECTION 2.16. Brokers. Except as contemplated by or referenced
in the May [14], 1997 letter agreement  between  McDonald & Company  Securities,
Inc.  ("McDonald")  and FFC, a true and complete copy of which FFC has delivered
to  Associated,  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 FFC or any FFC Subsidiary.

                  SECTION 2.17.  Pooling of Interests  and Tax Matters.  Neither
FFC nor, to the knowledge of FFC, 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  combination to be effected by the Merger as a
pooling of interests in accordance with generally accepted accounting principles
or would prevent the Merger from  qualifying as a  reorganization  under Section
368(a)  of the  Code.  FFC has no reason to  believe  that the  Merger  will not
qualify as a pooling of interest or as a reorganization  under Section 368(a) of
the Code.

                  SECTION  2.18.  Vote  Required.  The  affirmative  vote of the
holders of two-thirds of the  outstanding  Shares entitled to vote on the Merger
is the only FFC shareholder vote required with respect to the Merger.

                  SECTION 2.19.  Fairness  Opinion.  FFC has received an opinion
from McDonald to the effect that, in its opinion,  the  consideration to be paid
to shareholders of FFC under this Agreement is fair to such  shareholders from a
financial point of view ("FFC Fairness Opinion"),  and McDonald has consented to
the inclusion of the FFC Fairness Opinion in the Form S-4 (as defined below).


                                   ARTICLE III

                  REPRESENTATIONS AND WARRANTIES OF ASSOCIATED

                  Except as set forth in the  disclosure  schedule  delivered by
Associated to FFC prior to the execution of this Agreement  which shall identify
exceptions  by specific  Section  references;  provided  that  disclosure in one
schedule  will  be  deemed  to  satisfy  disclosure  in  another  schedule  (the
"Associated Disclosure Schedule"),  Associated hereby represents and warrants to
FFC that:



<PAGE>


                                       21

                  SECTION 3.01.  Organization  and  Qualification of Associated;
Subsidiaries.  (a) Associated, is a corporation duly organized, validly existing
and in good  standing  under the laws of the State of  Wisconsin.  Associated is
registered as a bank holding company with the Federal Reserve Board of Governors
of the Federal Reserve System (the "Federal Reserve Board") under the BHCA.

                  (b) Section 3.01 of the  Associated  Disclosure  Schedule sets
forth  a true  and  complete  list of each  of  Associated's  subsidiaries  (the
"Associated Subsidiaries"), all outstanding equity securities of each Associated
Subsidiaries and the percentages owned by Associated of such equity  securities.
Except as set forth in Section 3.01 of the Associated Disclosure Schedule,  each
Associated  Subsidiary is wholly owned,  directly or indirectly,  by Associated.
Except as set forth in Section 3.01 of the Associated  Disclosure Schedule,  all
outstanding  shares of capital stock of the Associated  Subsidiaries are validly
issued,   fully  paid  and   nonassessable   (except  as   provided  in  Section
180.0622(2)(b)  of  Wisconsin  Law)  and are free and  clear of any  Lien,  with
respect  thereto.  Each  Associated  Subsidiary is a  corporation,  partnership,
savings  bank,  savings and loan,  bank or trust  company duly  incorporated  or
organized  validly  existing  and  in  good  standing  under  the  laws  of  its
jurisdiction of incorporation or organization.

                  (c)  Associated  and  each   Associated   Subsidiary  has  the
requisite  corporate power and authority and is in possession of all franchises,
grants, authorizations,  licenses, permits, easements,  consents,  certificates,
approvals  and orders (the  "Associated  Permits")  necessary to own,  lease and
operate  its  properties  and to  carry  on  its  business  as it is  now  being
conducted,  except  where the failure to be so  organized,  existing and in good
standing or to have such power,  authority  and  Associated  Permits  would not,
either  individually  or in the  aggregate,  have a Material  Adverse  Effect on
Associated and the Associated Subsidiaries, taken as a whole. Associated has not
received any notice of proceedings relating to the revocation or modification of
any such Associated Permits except for any such revocation or modification which
would not,  either  individually  or in the aggregate,  have a Material  Adverse
Effect  on  Associated  and  the  Associated  Subsidiaries,  taken  as a  whole.
Associated  and each  Associated  Subsidiary is duly  qualified or licensed as a
foreign  corporation  to  do  business,   and  is  in  good  standing,  in  each
jurisdiction where the character of its properties owned,  leased or operated by
it or the  nature  of its  activities  makes  such  qualification  or  licensing
necessary,  except for such failures to be so duly  qualified or licensed and in
good standing that would not, either  individually  or in the aggregate,  have a
Material Adverse Effect on Associated and the Associated Subsidiaries,  taken as
a whole.

                  (d) Section 3.01 of the  Associated  Disclosure  Schedule sets
forth  with  respect  to  each   Associated   Subsidiary  that  is  a  financial
institution,  its form of charter  and the  insurance  fund which  insures  such
subsidiary's deposits.

                                       22

                  (e) Section 3.01 of the  Associated  Disclosure  Schedule sets
forth a true,  complete  and  correct  list of all  Corporate  Entities of which
Associated or any Associated Subsidiary holds or beneficially owns 5% or more of
the  outstanding  shares  of any  class of  voting  securities,  holds a general
partnership interest or other controlling  interest,  holds or beneficially owns
more than 24.9% of the  outstanding  capital stock (whether voting or nonvoting)
and  subordinated  debt or is  otherwise  deemed to be a  subsidiary  within the
meaning of the BHCA.

                  SECTION   3.02.   Articles   of   Incorporation   and  Bylaws.
Associated,  Merger Sub and Associated  Bank Green Bay, N.A. and Associated Bank
Milwaukee  (together,  the "Associated  Material  Subsidiaries") have heretofore
furnished  or made  available  to FFC a  complete  and  correct  copy  of  their
respective Articles of Incorporation and the Bylaws, as amended or restated. The
Associated Material Subsidiaries are Associated's only banking subsidiaries with
total assets (as reflected on the financial  statements of Associated's  banking
subsidiaries)  greater than $500  million.  Such Articles of  Incorporation  and
Bylaws are in full force and  effect and none of  Associated,  Merger Sub or the
Associated  Material  Subsidiaries  are in violation of any of the provisions of
their respective Articles of Incorporation or Bylaws.

                  SECTION   3.03.   Capitalization.    (a)   Capitalization   of
Associated.   The  authorized  capital  stock  of  Associated  consists  of  (i)
48,000,000  shares of  Associated  Common  Stock of which as of March 31,  1997,
22,439,000  shares were issued and outstanding,  all of such shares are, and the
shares of Associated  Common Stock to be issued pursuant to the Merger,  when so

securities laws, and (ii) 750,000 shares of preferred stock, par value $1.00 per

Associated  Stock Plans pursuant to which options  covering  1,262,577 shares of
Associated  Common Stock were  outstanding.  No options have been granted  since
March 31, 1997 to the date of this Agreement  under the Associated  Stock Plans.

are held as treasury stock by Associated.  Other than pursuant to the Associated
Stock  Option  Agreement  and the  Associated  Stock Plans there are no options,
warrants or other rights, rights of first refusal, agreements,  arrangements, or
commitments of any character relating to the issued or unissued capital stock of
Associated or obligating Associated to issue or sell any shares of capital stock
of,  or  other  equity  interests  in  Associated.  There  are  no  obligations,
contingent  or  otherwise,  of  Associated  to  repurchase,  redeem or otherwise
acquire any shares of

                                       23

Associated  Common Stock or to provide funds to or make any  investment  (in the
form  of a  loan,  capital  contribution  or  otherwise)  in  any  other  entity
(including any Associated Subsidiary).

                  (b) Capital Stock of the  Associated  Subsidiaries.  Except as
set forth in Section 3.03(b) of the Associated Disclosure Schedule, there are no
options,  warrants  or  other  rights,  rights  of  first  refusal,  agreements,
arrangements or commitments of any character  relating to the issued or unissued
capital  stock of the  Associated  Subsidiaries  or  obligating  any  Associated
Subsidiary  to issue or sell any  shares of  capital  stock of, or other  equity
interests in any Associated Subsidiary. There are no obligations,  contingent or
otherwise,  of any  Associated  Subsidiary  to  repurchase,  redeem or otherwise
acquire  any shares of the  capital  stock of any  Associated  Subsidiary  or to
provide  funds  to or  make  any  investment  (in the  form  of a loan,  capital
contribution or otherwise) in any other entity.

                  SECTION 3.04.  Authority.  Associated  and Merger Sub 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  Merger  Sub  and the  consummation  by  Associated  and  Merger  Sub of the
transactions  contemplated  hereby have been duly and validly  authorized by all
necessary corporate action on the part of Associated and Merger Sub and no other
corporate  proceedings  on the part of Associated or Merger Sub are necessary to
authorize this Agreement or to consummate the transactions  contemplated  hereby
(other than, with respect to the Merger,  the requisite approval to increase the
authorized number of, and the issuances of, shares of Associated Common Stock in
connection with the Merger).  This Agreement has been duly and validly  executed
and delivered by Associated and Merger Sub and, assuming the due  authorization,
execution  and  delivery  by FFC,  constitutes  the  legal,  valid  and  binding
obligation  of Associated  and Merger Sub  enforceable  in  accordance  with its
terms,  except as  enforcement  may be limited  by  bankruptcy,  insolvency  and
similar laws affecting  creditors' rights and remedies  generally and by general
principles of equity.

                  SECTION 3.05. No Conflict;  Required Filings and Consents. (a)
Except as set forth in Section 3.05 of the Associated  Disclosure Schedule,  the
execution and delivery of this  Agreement by Associated and Merger Sub does not,
and the  performance  of this  Agreement by Associated and Merger Sub shall not,
(i)  conflict  with or  violate  the  Articles  of  Incorporation  or  Bylaws of
Associated or any Associated Subsidiary,  (ii) conflict with or violate any Laws
applicable  to  Associated  or  any  Associated  Subsidiary,  or  by  which  its
respective 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
on any of the  properties or assets of Associated or any  Associated  Subsidiary
pursuant to any note, bond, mortgage, indenture, contract, agreement,


<PAGE>


                                       24

lease,  license,  permit,  franchise or other  instrument or obligation to which
Associated or any Associated Subsidiary is a party or by which Associated or any
Associated Subsidiary or its respective properties are bound or affected, except
(in the case of clauses  (ii) and (iii) of this  Section  3.05(a))  for any such
conflicts,  violations,  breaches, defaults or other occurrences that would not,
either  individually  or in the  aggregate,  have a Material  Adverse  Effect on
Associated and the Associated Subsidiaries, taken as a whole.

                  (b) The execution and delivery of this Agreement by Associated
and Merger Sub does not, and the performance of this Agreement by Associated and
Merger  Sub  shall  not,  require  any  Approval,   except  (i)  for  applicable
requirements,  if any, of (A) the Securities  Act, (B) the Exchange Act, (C) the
BHCA,  (D) HOLA,  (E) the OCC, (F) the FDIA, (G) Blue Sky Laws, (H) the WBL, (I)
the filing and recordation of appropriate  merger or other documents as required
by Wisconsin  Law, (J) the IBL, (K) the Nasdaq Stock Market,  (L) Insurance Laws
and (M) any  applicable  SRO and (ii) such  additional  Approvals the failure of
which to obtain  would not  prevent  or delay  consummation  of the  Merger,  or
otherwise  prevent  Associated and Merger Sub from performing their  obligations
under this Agreement,  and would not,  either  individually or in the aggregate,
have a Material  Adverse Effect on Associated  and the Associated  Subsidiaries,
taken as a whole.

                  SECTION  3.06.   Compliance.   Neither   Associated   nor  any
Associated  Subsidiary  is in conflict  with, or in default or violation of, (i)
any Law applicable to Associated or the Associated  Subsidiaries or by which any
of their  respective  properties are bound or affected,  or (ii) any note, bond,
mortgage,  indenture,  contract, agreement, lease, license, permit, franchise or
other instrument or obligation to which Associated or any Associated  Subsidiary
is a party or by which  Associated or any Associated  Subsidiary or any of their
respective  properties  are bound or  affected,  except for any such  conflicts,
defaults or violations which would not, either individually or in the aggregate,
have a Material  Adverse Effect on Associated  and the Associated  Subsidiaries,
taken as a whole.

                  SECTION  3.07.  Securities  and  Banking  Reports;   Financial
Statements.  (a)  Associated  and the  Associated  Subsidiaries  have  filed all
material forms, reports, registrations,  statements and documents, together with
any amendments required to be made with respect thereto that were required to be
filed since January 1, 1995 with the  Regulatory  Agencies and all Other Reports
required to be filed by Associated and any Associated  Subsidiary  since January
1,  1995,  and paid  all fees and  assessments  due and  payable  in  connection
therewith,  except, in the case of the Other Reports, where failure to file such
form,  report,  registration,  statement  or  document  or  pay  such  fees  and
assessments would not, either individually or in the aggregate,  have a Material
Adverse Effect on Associated and the Associated  Subsidiaries,  taken as a whole
(all such reports and statements are collectively referred to as the "Associated
Reports"). The Associated Reports,  including all Associated 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


<PAGE>


                                       25

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 (including,
in each case, any related notes  thereto)  contained in any filings with the SEC
since January 1, 1995 (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, or will be,  prepared in accordance  with generally
accepted  accounting  principles  applied on a consistent  basis  throughout the
periods  involved (except as the may be indicated in the notes thereto) and each
fairly  presents,  or  will  fairly  present,  in  all  material  respects,  the
consolidated financial position of Associated and the Associated 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 the Associated  Subsidiaries  as of December 31,
1996,  including all notes thereto (the  "Associated  Balance  Sheet"),  neither
Associated nor any Associated  Subsidiary has any  liabilities or obligations of
any nature (whether accrued, absolute,  contingent or otherwise), except for (i)
liabilities  or  obligations  incurred in the ordinary  course of business since
December 31, 1996 and (ii)  liabilities  or obligations  that would not,  either
individually or in the aggregate,  have a Material  Adverse Effect on Associated
and the Associated Subsidiaries, taken as a whole.

                  SECTION 3.08. Absence of Certain Changes or Events. (a) Except
as  disclosed  in the  Associated  SEC  Reports  filed prior to the date of this
Agreement,   since   December  31,  1996,  (i)  Associated  and  the  Associated
Subsidiaries  have conducted their businesses only in the ordinary course and in
a manner  consistent  with past  practice and (ii) there has been no event which
has had, or is  reasonably  likely to result in, either  individually  or in the
aggregate,   a  Material   Adverse  Effect  on  Associated  and  the  Associated
Subsidiaries, taken as a whole.

                  SECTION 3.09. Absence of Litigation and Agreements. (a) Except
as  disclosed  in the  Associated  SEC  Reports  filed prior to the date of this
Agreement or set forth in Section 3.09 of the  Associated  Disclosure  Schedule,
(i)  neither  Associated  nor  any  Associated  Subsidiary  is  subject  to  any
continuing order of, or written  agreement or memorandum of understanding  with,
or  continuing  investigation  by, any federal or state savings and loan or bank

entity or regulatory  authority or arbitrator,  including,  without  limitation,
cease-and-desist or other orders which, either individually or in the aggregate,
would have or  reasonably be expected to have a Material  Adverse  Effect on the
Associated and the Associated  Subsidiaries,  taken as a whole; (ii) there is no
claim  of  any  kind,  action,  suit,   litigation,   proceeding,   arbitration,
investigation,   or   controversy   affecting   Associated  or  the   Associated

as of the date of this Agreement,  for matters which  individually  seek damages
not in excess of $500,000  and (B) as of the Closing,  for matters  which cannot
reasonably  be expected to have,  either  individually  or in the  aggregate,  a
Material Adverse Effect on Associated and the Associated Subsidiaries,  taken as
a whole; and (iii) there are not uncured violations,  or violations with respect
to which refunds or restitutions may be required, cited in any compliance report
to Associated or the Associated  Subsidiaries  as a result of the examination by

have,  either  individually  or in the aggregate,  a Material  Adverse Effect on
Associated and the Associated Subsidiaries, taken as a whole.

                  (b) Except as set forth on the Associated  Disclosure Schedule
at Section 3.09, neither Associated nor any of the Associated  Subsidiaries is a
party to any written agreement or memorandum of understanding  with, or party to
any commitment letter,  board resolution  submitted to a regulatory authority or
similar  undertaking  to, or is  subject to any order or  directive  by, or is a
recipient of any extraordinary  supervisory letter from any governmental  entity
or agency which  restricts  materially  the conduct of its  business,  or in any
manner relates to its capital  adequacy,  its credit or reserve  policies or its
management nor has  Associated or any Associated  Subsidiary (i) been advised by
any governmental entity or agency that it 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 or (ii) have knowledge of any
pending or  threatened  regulatory  investigation.  Neither  Associated  nor any
Associated Subsidiary is required by Section 32 of the Federal Deposit Insurance
Act to give prior notice to a Federal banking agency of the proposed addition of
an individual to its board of directors or the  employment of an individual as a
senior executive officer.

                  SECTION 3.10.  Employee  Benefit Plans. (a) Since December 31,
1996,  there has not been any adoption or  amendment in any material  respect by
Associated  or  any  Associated   Subsidiary  of  any  employment,   consulting,

sharing, deferred compensation,  incentive compensation,  stock ownership, stock
purchase,  stock  option,  phantom  stock,  retirement,   vacation,   severance,
disability, death benefit,  hospitalization,  medical or other plan, arrangement
or understanding  providing benefits to any current or former employee,  officer
or director of  Associated  or any  Associated  Subsidiary  (collectively,  such
agreements, plans, arrangements and understandings being the "Associated Benefit
Plans"),  or any material  change in any actuarial or other  assumption  used to
calculate funding obligations with respect to any


<PAGE>


                                       27

Associated pension plans, or any change in the manner in which  contributions to
any Associated  pension plans are made or the basis on which such  contributions
are determined.

                  (b) Section 3.10 of the  Associated  Disclosure  Schedule sets
forth a list of all Associated  Benefit Plans.  Associated has delivered or made
available  to FFC true and  complete  copies  of all  Associated  Benefit  Plans
together with all current related  documents,  including the most recent summary
plan  descriptions,   IRS  determination   letters  and  actuarial  reports,  if
applicable.

                  (c) (i) Except as disclosed in Section 3.10 of the  Associated
         Disclosure Schedule, with respect to Associated Benefit Plans, no event
         has  occurred  and, to the  knowledge  of  Associated,  there exists no
         condition or set of circumstances,  in connection with which Associated
         or any of the Associated Subsidiaries could be subject to any liability
         that  individually  or in the aggregate  would have a Material  Adverse
         Effect on the Associated and the  Associated  Subsidiaries,  taken as a
         whole, under ERISA, the Code or any other applicable law.

                  (ii) Each  Associated  Benefit Plan has been  administered  in
         accordance with its terms, except for any failures so to administer any
         Associated Benefit Plan that individually or in the aggregate would not
         have a  Material  Adverse  Effect  on  Associated  and  the  Associated
         Subsidiaries, taken as a whole. Associated, the Associated Subsidiaries
         and all Associated  Benefit Plans are in compliance with the applicable
         provisions  of ERISA,  the Code and all other  applicable  laws and the
         terms of all applicable  collective bargaining  agreements,  except for
         any  failures  to be in such  compliance  that  individually  or in the
         aggregate  would not have a Material  Adverse  Effect on Associated and
         the Associated Subsidiaries,  taken as a whole. Each Associated Benefit
         Plan that is intended to be qualified under Section 401(a) or 401(k) of
         the Code has  received a  favorable  determination  letter from the IRS
         that it is so qualified and each trust  established in connection  with
         any Associated  Benefit Plan that is intended to be exempt from Federal
         income  taxation  under  Section  501(a)  of the  Code has  received  a
         determination  letter from the IRS that such trust is so exempt. To the
         knowledge of Associated,  no fact or event has occurred since that date
         of any determination  letter from the IRS which is reasonably likely to
         affect  adversely the qualified  status of any such Associated  Benefit
         Plan or the exempt status of any such trust.

                  (iii)   Neither   Associated   nor   any  of  the   Associated
         Subsidiaries  has incurred any liability under Title IV of ERISA (other
         than liability for premiums to the Pension Benefit Guaranty Corporation
         arising  in the  ordinary  course).  No  Associated  Benefit  Plan  has
         incurred an  "accumulated  funding  deficiency"  (within the meaning of
         Section 302 of ERISA or Section 412 of the Code) whether or not waived.
         To  the   knowledge  of   Associated,   there  are  not  any  facts  or
         circumstances that would


<PAGE>


                                       28

         materially change the funded status of any Associated Benefit Plan that
         is a "defined  benefit"  plan (as  defined  in Section  3(35) of ERISA)
         since the date of the most recent  actuarial  report for such plan.  No
         Associated Benefit Plan is a "multiemployer plan" within the meaning of
         Section 3(37) of ERISA.

                  (iv) Neither Associated nor any of the Associated Subsidiaries
         is a party to any  collective  bargaining or other labor union contract
         applicable to persons  employed by Associated or any of the  Associated
         Subsidiaries and no collective bargaining agreement is being negotiated
         by Associated or any of the Associated Subsidiaries.  There is no labor
         dispute,  strike  or work  stoppage  against  Associated  or any of the
         Associated  Subsidiaries  pending or, to the  knowledge of  Associated,
         threatened which may interfere with the respective  business activities
         of Associated or any Associated Subsidiary,  except where such dispute,
         strike or work stoppage individually or in the aggregate would not have
         a  Material   Adverse   Effect  on   Associated   and  the   Associated
         Subsidiaries,  taken as a whole. As of the date of this  Agreement,  to
         the knowledge of Associated,  none of Associated, any of the Associated
         Subsidiaries or any of their  respective  representatives  or employees
         has  committed  any  unfair  labor  practice  in  connection  with  the
         operation of the  respective  businesses  of  Associated  or any of the
         Associated  Subsidiaries,  and there is no charge or complaint  against
         Associated or any of the Associated  Subsidiaries by the National Labor
         Relations  Board  or any  comparable  governmental  agency  pending  or
         threatened in writing.

                  (v) Except as referenced in this Agreement or  contemplated by
         this  Agreement  and  except  as  set  forth  in  Section  3.10  of the
         Associated  Disclosure  Schedule,  no  employee  of  Associated  or any
         Associated  Subsidiary  will be entitled to any additional  benefits or
         any  acceleration  of the time of payment  or  vesting of any  benefits
         under  any  Associated  Benefit  Plan as a result  of the  transactions
         contemplated by this Agreement or the Option Agreements.

                  (vi) No payment or benefit  will or may be made by  Associated
         or any  Associated  Subsidiary  with  respect  to any  employee  or any
         current of former  director  that will be  characterized  as an "excess
         parachute payment" within the meaning of Section 280G(b) of the Code.

                  SECTION  3.11.  Material  Contracts.  Except  as set  forth in
Section  3.11 of the  Associated  Disclosure  Schedule,  as of the  date of this
Agreement,  neither  Associated nor any  Associated  Subsidiary is a party to or
bound by (a) any contract or commitment  for capital  expenditures  in excess of
$500,000 for any one project,  (b) 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 and calling for  aggregate  future
payments of $1,000,000  or more during the term of such contract or  commitment,
(c) any contract which is a "material contract" (as such term is defined in Item
601(b)(10) of Regulation S-K of the


<PAGE>


                                       29

SEC) that has not been filed or  incorporated by reference in the Associated SEC
Reports, (d) any contract which contains  non-compete or exclusivity  provisions
or  restrictions  with respect to any business or  geographic  area or (e) which
would prohibit or materially  delay the  consummation of the Merger or any other
transaction  contemplated  by  this  Agreement.   Each  contract,   arrangement,
commitment or understanding of the type described in this Section 3.11,  whether
or not set forth in Section 3.11 of Associated  Disclosure Schedule, is referred
to herein as a "Associated  Contract".  Neither Associated nor any of Associated
Subsidiary  knows of, or has received notice of, any violation of any Associated
Contract  by any of the other  parties  thereto,  except for  violations  which,
individually or in the aggregate,  would not result in a Material Adverse Effect
on Associated and Associated Subsidiaries, taken as a whole.

                  SECTION  3.12.  Environmental  Matters.  To the  knowledge  of
Associated neither  Associated,  any Associated  Subsidiary,  nor any properties
owned or operated by Associated or any  Associated  Subsidiary has been or is in
violation of or liable under any  Environmental  Law, except for such violations
or liabilities that, individually or in the aggregate, are not reasonably likely
to have a Material Adverse Effect on Associated and the Associated Subsidiaries,
taken as a whole.  There  are no  actions,  suits or  proceedings,  or  demands,
claims, notices or investigations  (including without limitation notices, demand
letters or requests of information from any environmental  agency) instituted or
pending,  or to  the  knowledge  of  Associated,  threatened,  relating  to  the
liability  of  Associated  or any  Associated  Subsidiary  with  respect  to any
properties  owned or operated by Associated or any Associated  Subsidiary  under
any  Environmental  Law,  except for  liabilities  or violations  that would not
reasonably be expected to have,  individually  or in the  aggregate,  a Material
Adverse Effect on Associated and the Associated Subsidiaries, taken as a whole.

                  SECTION 3.13.  Taxes. (a) Except for such matters as would not
have,  individually or in the aggregate, a Material Adverse Effect on Associated
and the  Associated  Subsidiaries,  taken as a  whole,  (i)  Associated  and the
Associated  Subsidiaries  have timely  filed or will timely file all returns and
reports  required to be filed by them with any taxing  authority with respect to
Taxes for any period ending on or before the Effective Time, taking into account
any extension of time to file granted to or obtained on behalf of Associated and
the Associated Subsidiaries,  (ii) all Taxes that are due prior to the Effective
Time have  been paid or will be paid  (other  than  Taxes  which (1) are not yet
delinquent  or (2) are being  contested  in good faith and have not been finally
determined),  (iii) as of the date hereof,  no  deficiency  for any Tax has been
asserted or  assessed by a taxing  authority  against  Associated  or any of the
Associated  Subsidiaries  which  deficiency  has not been  paid  other  than any
deficiency  being contested in good faith and (iv) Associated and the Associated
Subsidiaries  have provided  adequate  reserves (in  accordance  with  generally
accepted accounting principles) in their financial statements for any Taxes that
have not been paid, whether or not shown as being due on any returns.



<PAGE>


                                       30

                  (b) To the  knowledge  of  Associated,  there are no  material
disputes  pending,  or claims asserted in writing for, Taxes or assessments upon
Associated, or any of the Associated Subsidiaries,  nor has Associated or any of
the  Associated  Subsidiaries  been  requested in writing to give any  currently
effective waivers extending the statutory period of limitation applicable to any
federal  or state  income tax return  for any  period  which  disputes,  claims,
assessments or waivers would have,  individually or in the aggregate, a Material
Adverse Effect on Associated and the Associated Subsidiaries, taken as a whole.

                  (c)  There  are no Tax liens  upon any  property  or assets of
Associated or any of the Associated  Subsidiaries except liens for current Taxes
not yet due and  except  for  liens  which  have not had and are not  reasonably
likely to have,  individually or in the aggregate,  a Material Adverse Effect on
Associated and the Associated Subsidiaries, taken as a whole.

                  (d) Neither Associated nor any of the Associated  Subsidiaries
has been required to include in income any adjustment pursuant to Section 481 of
the Code by reason of a  voluntary  change in  accounting  method  initiated  by
Associated or any of the Associated Subsidiaries,  and the IRS has not initiated
or proposed any such adjustment or change in accounting  method,  in either case
which  adjustment  or change would have,  individually  or in the  aggregate,  a
Material Adverse Effect on Associated and the Associated Subsidiaries,  taken as
a whole.

                  (e) Except as set forth in the financial  statements described
in Section 3.07, neither  Associated nor any of the Associated  Subsidiaries has
entered into a transaction  which is being  accounted for under the  installment
method of Section  453 of the Code,  which would  have,  individually  or in the
aggregate,   a  Material   Adverse  Effect  on  Associated  and  the  Associated
Subsidiaries, taken as a whole.

                  SECTION   3.14.   Derivative   Instruments.   All   Derivative
Instruments to which  Associated or any  Associated  Subsidiary is a party or to
which any of their  properties or assets may be subject were entered into in the
ordinary  course of business and, to the knowledge of Associated,  in accordance
with prudent banking practice and applicable rules, regulations, and policies of
the  regulatory  agencies  and with  counterparties  believed to be  financially
responsible at the time and, to knowledge of Associated,  are legal,  valid, and
binding obligations enforceable in accordance with their terms (except as may be
limited by bankruptcy, insolvency,  moratorium,  reorganization, or similar laws
affecting the rights of creditors  generally,  and the availability of equitable
remedies),  and, to the knowledge of  Associated,  are in full force and effect.
Associated  and each  Associated  Subsidiary  has duly performed in all material
respects all of its obligations  under any such Derivative  Instruments,  and to
the knowledge of Associated,  there are no breaches,  violations, or defaults or
allegations  or assertions of such by any party  thereunder  except for any such
breaches,  violations, or defaults or allegations or assertions which would not,
individually or


<PAGE>


                                       31

in the  aggregate,  have  a  Material  Adverse  Effect  on  Associated  and  the
Associated Subsidiaries, taken as a whole.

                  SECTION 3.15. Regulatory Approvals. Associated is not aware of
any  aspect  of, or issues  relating  to,  its or the  Associated  Subsidiaries'
operations and business that would prevent the condition of Closing set forth in
Section 6.01(c) from being satisfied.

                  SECTION 3.16. Brokers. Except as contemplated by or referenced
in the March 26, 1997 letter agreement between Sandler O'Neill & Partners,  L.P.
("Sandler O'Neill") and Associated, a true and complete copy of which Associated
has delivered to FFC, 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 or any Associated Subsidiary.

                  SECTION  3.17.  Pooling of Interest and Tax  Matters.  Neither
Associated  nor, to the  knowledge  of  Associated,  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  combination to be effected
by the Merger as a pooling of interests in accordance  with  generally  accepted
accounting  principles  or  would  prevent  the  Merger  from  qualifying  as  a
reorganization  under Section  368(a) of the Code.  Associated  has no reason to
believe  that the Merger  will not  qualify as a pooling  of  interests  or as a
reorganization under Section 368(a) of the Code.

                  SECTION 3.18. Vote Required. The requisite affirmative vote of
holders of a majority of the outstanding  shares of the Associated  Common Stock
with respect to authorization of additional shares of Associated Common Stock in
accordance with the Associated's  Articles of Incorporation  and the issuance of
shares of Associated  Common Stock in connection with the Merger pursuant to the
rules of the  NASDAQ is the only vote of the  holders  of any class or series of
Associated's capital stock necessary with respect to the Merger.

                  SECTION 3.19.  Fairness  Opinion.  Associated  has received an
opinion  from  Sandler   O'Neill  to  the  effect  that  in  its  opinion,   the
consideration  to be paid to shareholders of FFC under this Agreement is fair to
such  shareholders  from  a  financial  point  of  view  ("Associated   Fairness
Opinion"),  and Sandler O'Neill has consented to the inclusion of the Associated
Fairness Opinion in the Form S-4.

                                   ARTICLE IV

                         COVENANTS OF FFC AND ASSOCIATED

                  SECTION  4.01.   Affirmative   Covenants.   Each  of  FFC  and
Associated  hereby  covenants  and  agrees  with  the  other  that  prior to the
Effective  Time,  unless the prior written  consent of the other shall have been
obtained and except as otherwise  contemplated  herein, FFC will, and will cause
each FFC  Subsidiary to, and  Associated  will,  and will cause each  Associated
Subsidiary to,  conduct their  respective  businesses in the ordinary  course of
business  in a manner  consistent  with  past  practice,  use  their  respective
reasonable   best  efforts  to  preserve   intact  their   respective   business
organizations, keep available the services of their respective current officers,

relationships.

                  SECTION 4.02. Negative Covenants.  Except set forth in Section
4.02 of the Associated  Disclosure Schedule or the FFC Disclosure  Schedule,  as
applicable,  and except as specifically contemplated by this Agreement, from the

shall not do, and, in the case of FFC,  permit the FFC  Subsidiaries to do, and,
in the case of Associated, permit the Associated Subsidiaries to do, without the
prior written consent of Associated or FFC, as applicable, any of the following:

                  (a) adjust,  split,  combine or reclassify  any capital stock,
         declare  or pay any  dividend  on,  or make any other  distribution  in
         respect  of,  its  outstanding  shares of  capital  stock,  except  for
         quarterly  dividend  declarations  and payments in accordance with past
         practice  and  in  per  share  amounts  not  materially  in  excess  of
         historical per share dividend amounts;  provided,  however,  that after
         the date of this Agreement, each of Associated and FFC shall coordinate
         with  the  other  the  declaration  of  any  dividends  in  respect  of
         Associated  Common  Stock and FFC Common Stock and the record dates and

         hereto that  holders of  Associated  Common  Stock or FFC Common  Stock
         shall not receive two dividends,  or fail to receive one dividend,  for
         any quarter  with respect to their  shares of  Associated  Common Stock
         and/or FFC Common Stock and any shares of  Associated  Common Stock any

         within the meaning of Section 368 of the Code:  provided,  however that
         nothing  contained  herein shall limit the ability of Associated or FFC
         to exercise  its rights  under the FFC Stock  Option  Agreement  or the
         Associated Stock Option Agreement, respectively;

                  (k) take any action  that is  intended  or may  reasonably  be

         forth  in this  Agreement  being or  becoming  untrue  in any  material
         respect  at any time  prior  to the  Effective  Time,  or in any of the
         conditions to the Merger set forth in Article VI not being satisfied or
         in a violation of any  provision  of this  Agreement,  except,  in each
         case, as may be required by applicable law;

                  (l)  take  any  action  or  fail  to  take  any  action  which

         Material  Adverse  Effect  on,  in the  case  of  FFC,  FFC and the FFC
         Subsidiaries,  taken  as  a  whole  or,  in  the  case  of  Associated,
         Associated and the Associated Subsidiaries, taken as a whole; or

                  (m) agree in writing or otherwise to do any of the foregoing.


                                    ARTICLE V

                              ADDITIONAL AGREEMENTS

                  SECTION  5.01.  Registration  Statement.  (a) As  promptly  as
practicable after the execution of this Agreement,  (i) FFC and Associated shall
prepare and file with the SEC preliminary proxy materials which shall constitute
the joint proxy  statement of Associated and FFC (such joint proxy  statement as
amended or  supplemented  is referred to herein as the "Joint Proxy  Statement")
and (ii) Associated shall prepare and file a registration  statement on Form S-4
(together with any amendments thereto, the "Registration  Statement"),  in which

respect to the  registration of the Associated  Common Stock to be issued in the
Merger.  Associated and FFC shall each use its reasonable  best efforts to cause

Statement. Associated and FFC will each render to the other its full cooperation
in preparing,  filing,  prosecuting the filing of, and amending the Registration
Statement  such that it  comports  at all  times  with the  requirements  of the
Securities  Act and the Exchange Act.  Each of Associated  and FFC will promptly
advise  the other if at any time  prior to the  Effective  Time any  information
provided by it for  inclusion in the  Registration  Statement or the Joint Proxy

appears to have been,  or shall have become,  incorrect or  incomplete  and will
furnish the information necessary to correct such misstatements or omissions. As
promptly  as  practicable  after the  Registration  Statement  shall have become

extent  that the Board of  Directors  of FFC  determines  in good  faith,  after
consultation with and based upon the advice of independent  legal counsel,  that
the failure to so withdraw,  modify or change its recommendation would cause the
Board of Directors of FFC to breach its fiduciary  duties to FFC's  shareholders

shall not constitute a breach of this Agreement by FFC.

approval  of a  Superior  Competing  Transaction,  the  Board  of  Directors  of
Associated may, at any time prior to such time as the  shareholders of FFC shall
have adopted and  approved  this  Agreement in  accordance  with  Wisconsin  Law
withdraw, modify, or change any such recommendation to the extent that the Board
of Directors of Associated determines in good faith, after consultation with and
based upon the  advice of  independent  legal  counsel,  that the  failure to so
withdraw, modify or change its recommendation would cause the Board of Directors
of Associated to breach its fiduciary duties to Associated's  shareholders under
applicable law and,  notwithstanding  anything to the contrary contained in this
Agreement,  any such withdrawal,  modification or change of recommendation shall
not constitute a breach of this Agreement by Associated.

all losses, expenses,  claims, damages,  liabilities or amounts that are paid in
settlement  of (with the approval of Associated  and the Surviving  Corporation,
which will not be unreasonably  withheld),  or otherwise in connection with, any

in part on the fact  that  such  person is or was such a  director,  officer  or
employee  and arising out of actions or  omissions  occurring at or prior to the

advance  of the  final  disposition  of any such  action or  proceeding  to each
Indemnified  Party to the fullest  extent  permitted  under  Wisconsin Law, upon
receipt  from  the  Indemnified  Party  to whom  expenses  are  advanced  of the
undertaking to repay such advances).

                  (b) Any  Indemnified  Party  wishing to claim  indemnification
under  this  Section  5.06,  upon  learning  of any  such  Claim,  shall  notify
Associated  and the  Surviving  Corporation  (although  the failure so to notify
Associated and the Surviving  Corporation  shall not relieve either thereof from
any liability that  Associated or the Surviving  Corporation may have under this
Section  5.06,  except to the extent such  failure  materially  prejudices  such
party).  Associated and the Surviving Corporation shall have the right to assume
the defense thereof and if such right is exercised  Associated and the Surviving

expenses of other counsel or any other  expenses  subsequently  incurred by such

satisfactory  to  them,  and,  in  such  case,   Associated  and  the  Surviving
Corporation  shall pay all reasonable  fees and expenses of such counsel for the
Indemnified  Parties  promptly as statements  therefor are  received;  provided,

similar

actions or proceedings  arising out of the same general  allegations,  be liable
for the fees and  expenses of more than one  separate  firm of  attorneys at any
time for all  Indemnified  Parties except to the extent that local  counsel,  in
addition to such parties' regular counsel, is necessary or desirable in order to
effectively  defend  against such action or  proceeding,  (ii)  Associated,  the
Surviving  Corporation and the Indemnified Parties will cooperate in the defense
of any such matter, or (iii) Associated and the Surviving  Corporation shall not
be liable for any settlement  effected without its prior written consent,  which

that the Surviving  Corporation  shall not have any obligation  hereunder to any
Indemnified Party when and if a court of competent jurisdiction shall ultimately
determine,  and such  determination  shall have become  final and not subject to
further appeal, that the indemnification of such Indemnified Party in the manner
contemplated  hereby is prohibited by applicable law. No Indemnified Party shall
consent  to entry of any  judgment  or enter into any  settlement  that does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such  Indemnified  Party  of a  release,  in form  and  substance  reasonably
satisfactory to such  Indemnified  Party,  from all liability in respect of such
claim or  litigation  for which such  Indemnified  Party  would be  entitled  to
indemnification hereunder.

                  (c) Associated  shall use its reasonable best efforts to cause
to be maintained in effect for not less than two years after the Effective  Time
(except to the extent not  generally  available  in the market)  directors'  and
officers'   liability  insurance  and  fiduciary  liability  insurance  that  is
substantially  equivalent  in coverage  to FFC's  current  insurance;  provided,
however, that Associated shall not be required to pay an annual premium for such
insurance in excess of 150% of the last annual premium paid prior to the date of
this Agreement,  and in such case shall purchase as much comparable  coverage as
possible for such amount.

                  (d) This  Section  5.06 is  intended to be for the benefit of,
and shall be enforceable by, the Indemnified  Parties referred to herein,  their
heirs and personal representatives and shall be binding on Associated and Merger
Sub and the Surviving Corporation and their respective successors and assigns.

                  (b) Notwithstanding any provisions of the contracts, plans and
arrangements  listed  in  Section  5.09  of the  FFC  Disclosure  Schedule,  the
following contracts, plans and arrangements shall be treated as follows:

                  (i) FFC's Directors'  Retirement Plan,  effective November 18,
         1992 (the "Directors' Plan"), shall be terminated immediately after the
         Effective Time of the Merger, and, accordingly, (a) each person serving
         as a director of FFC on the date  hereof  ("Current  Directors")  shall
         receive  in  a  lump  sum  cash  payment  his  fully  vested   benefits
         thereunder,  with no  reduction  as a result  of any  Current  Director
         having not attained age 70, and (b) each former  director of FFC who is
         currently  receiving  benefits under the Directors'  Plan shall receive
         benefits as provided under Section 4.6 of the Directors' Plan.

                  (ii)  Each  of  the  persons  subject  to the  employment  and
         severance  agreements  listed  in  Section  5.09 of the FFC  Disclosure
         Schedule  who  delivers  a  written  consent  to  Parent  prior  to the
         Effective  Time,  which  consent  permits  the  payment of  benefits in
         accordance  herewith,  shall be paid the benefits  specified at Section
         5.09(b)(ii) of the FFC Disclosure  Schedule (the "Benefits") in lieu of
         any  severance  benefits  which  otherwise  would be due to such person
         following  termination  upon the Merger.  Associated  shall provide the
         Benefits to such persons upon the first


<PAGE>


                                       44

         to occur of (x) two years following the Effective Time; (y) termination
         of such  employee by reason of death or  disability,  or for other than
         "Cause"  or  (z)  resignation  of  such  employee  for  "Good  Reason";
         provided,  however,  that  post-retirement  continuation  of healthcare
         benefits will be provided only upon the occurrence of (y) or (z) above,
         on or prior to the second  anniversary  of the  Effective  Time. In the
         event of the  termination of any such person for Cause or a resignation
         without Good Reason  occurring  prior to the second  anniversary of the
         Effective  Time,  such person shall have no right to the Benefits or to
         any other severance  benefits under the relevant  agreements  listed in
         Section 5.09 of the Disclosure  Schedule or any other plan,  program or
         arrangement.  The  term  "Cause"  means  personal  dishonesty,  willful
         misconduct,   breach  of  fiduciary  duty  involving  personal  profit,
         intentional failure to perform stated duties,  willful violation of any
         law, rule, or regulation involving dishonesty or breach of trust, which
         is a crime punishable by imprisonment for a term exceeding one year, or
         otherwise  involving  unsafe  or  unsound  banking  practices,  willful
         violation or being the subject of a final  cease-and-desist  order. The
         term "Good Reason" means a reduction in the  compensation,  or material
         reduction   in   the   benefits,   position,   authority,   duties   or
         responsibilities  of the employee from those which existed prior to the
         date hereof;  a reduction in the employee's job stature as reflected in
         his  title;  or a change by more than 50 miles of the  location  of the
         employee's  job;  provided,  however,  that  nothing  herein  shall  be
         construed  to mean that the mere fact that an  employee's  position  is
         with a subsidiary of a public  company  rather than in a public company
         itself  constitutes Good Reason.  Neither execution and delivery of the
         aforementioned  consent or payment of the Benefits  shall  constitute a
         waiver or satisfaction, or otherwise effect the terms of the employment
         and severance  agreements  listed in Section 5.09 of the FFC Disclosure
         Schedule,  except  with  respect  to the  right  to  receive  severance
         benefits following termination upon the Merger.

This  Section  5.09(b)  is  intended  to be for the  benefit  of,  and  shall be
enforceable by, the individuals  subject to the provisions of Section 5.09(b)(i)
and (b)(ii)  above,  their  heirs,  and personal  representatives,  and shall be
binding on  Associated  and Merger Sub and the Surviving  Corporation  and their
respective successors and assigns.

                  (c) Following the Merger,  it is the intent of Associated  and
the Surviving  Corporation  that such entities will, and will cause any of their
respective  direct and indirect  subsidiaries  to, in connection  with reviewing
candidates for employment  positions,  give equal opportunity for such positions
to employees of Associated  and any Associated  Subsidiaries  and of FFC and any
FFC  Subsidiaries.  In  addition,  for  purposes  of the  Associated  Work Force
Management  Plan  (the  "Work  Force  Plan"),  employees  of FFC will be  deemed
associates  of  Associated,  and will be accorded  equal  priority in the hiring
process. Furthermore, effective as of the Effective Time, Associated shall adopt
an  amendment  to its  Work  Force  Plan (as well as  conforming  amendments  to
Associated's Severance Pay Plan)

FFC or  Associated,  as the case may be, to comply with or satisfy any covenant,
condition,  or  agreement  to be complied  with or  satisfied  by it  hereunder;
provided, however, that the delivery of any notice pursuant to this Section 5.10

party receiving such notice.

                  SECTION 5.12. Expenses.  (a) All Expenses (as described below)

names and addresses of the  shareholders  of FFC,  their holdings of stock as of
the  latest  practicable  date,  and  such  other  shareholder   information  as
Associated may reasonably request.

         Associated Subsidiaries, taken as a whole.

                  (d)  Affiliate  Letters.  Associated  shall have received from

         representation,  warranty, covenant or agreement on the part of FFC set

                            FORM OF AFFILIATE LETTER

                                    [ ], 1997


Associated Banc-Corp
112 North Adams Street
P.O. Box 13307
Green Bay, WI  54307-3307

Gentlemen:

                  I have been  advised  that as of the date of this letter I may
be deemed to be an  "affiliate"  of First  Financial  Corporation,  a  Wisconsin
corporation (the "Company"), as the term "affiliate" is (i) defined for purposes
of paragraphs (c) and (d) of Rule 145 of the rules and  regulations  (the "Rules
and Regulations") of the Securities and Exchange  Commission (the  "Commission")
under the  Securities  Act of 1933, as amended (the "Act"),  and/or (ii) used in
and for purposes of Accounting  Series Releases 130 and 135, as amended,  of the
Commission.  Pursuant to the terms of the Merger  Agreement  dated as of May 14,
1997 (the  "Agreement"),  among Associated  Banc-Corp,  a Wisconsin  corporation
("Associated"), Badger Merger Corp., a Wisconsin corporation ("Merger Sub"), and
the Company, Merger Sub will be merged with and into the Company (the "Merger").

                  As a result  of the  Merger,  I may  receive  shares of common
stock, par value $.01 per share, of Associated (the "Associated Securities").  I
would receive such shares in exchange for, respectively,  shares (or options for
shares) owned by me of common stock,  par value $1.00 per share,  of the Company
(the "Company Securities").

                  I represent,  warrant and covenant to  Associated  that in the
event I receive any Associated Securities as a result of the Merger:

                  A. I will not make any sale,  transfer or other disposition of
the Associated Securities in violation of the Act or the Rules and Regulations.

                  B. I have  carefully  read this letter and the  Agreement  and
         discussed  the  requirements  of such  documents  and other  applicable
         limitations upon my ability to sell,  transfer or otherwise  dispose of
         Associated Securities,  to the extent I felt necessary, with my counsel
         or counsel for the Company.

                  C. I  have  been  advised  that  the  issuance  of  Associated
Securities to me pursuant to the Merger has been  registered with the Commission
under the Act on a Registration Statement on Form S-4. However, I have also been
advised that,



<PAGE>


                                        2

         because I may be deemed to have been an affiliate of the Company at the
         time the Merger was  submitted  for a vote of the  shareholders  of the
         Company and the distribution by me of the Associated Securities has not
         been  registered  under the Act, I may not sell,  transfer or otherwise
         dispose of Associated  Securities issued to me in the Merger unless (i)
         such sale,  transfer or other disposition has been registered under the
         Act,  (ii)  such  sale,  transfer  or  other  disposition  is  made  in
         conformity   with  the  volume  and  other   limitations  of  Rule  145
         promulgated by the Commission under the Act, or (iii) in the opinion of
         counsel  reasonably  acceptable to Associated,  such sale,  transfer or
         other disposition is otherwise exempt from registration under the Act.

                  D. I understand  that  Associated  is under no  obligation  to
         register  the sale,  transfer or other  disposition  of the  Associated
         Securities  by me or on my  behalf  under  the Act or to take any other
         action  necessary in order to make  compliance  with an exemption  from
         such registration available.

                  E. I also understand that stop transfer  instructions  will be
         given to  Associated's  transfer  agents with respect to the Associated
         Securities  and that there will be placed on the  certificates  for the
         Associated  Securities issued to me, or any substitutions  therefor,  a
         legend stating in substance:

                  "THE SHARES  EVIDENCED  BY THIS  CERTIFICATE  WERE ISSUED IN A
                  TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES
                  ACT OF 1933 APPLIES.  THE SHARES EVIDENCED BY THIS CERTIFICATE
                  MAY ONLY BE  TRANSFERRED  IN  ACCORDANCE  WITH THE TERMS OF AN
                  AGREEMENT  DATED MAY 14, 1997  BETWEEN THE  REGISTERED  HOLDER
                  HEREOF AND ASSOCIATED, A COPY OF WHICH AGREEMENT IS ON FILE AT
                  THE PRINCIPAL OFFICES OF ASSOCIATED."

                  F. I also  understand  that  unless the  transfer  by me of my
         Associated  Securities has been  registered  under the Act or is a sale
         made in conformity with the provisions of Rule 145, Associated reserves
         the right to put the following legend on the certificates  issued to my
         transferee:

                  "THE  SHARES  EVIDENCED  BY THIS  CERTIFICATE  HAVE  NOT  BEEN
                  REGISTERED  UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED
                  FROM A PERSON WHO  RECEIVED  SUCH SHARES IN A  TRANSACTION  TO
                  WHICH RULE 145  PROMULGATED  UNDER THE  SECURITIES ACT OF 1933
                  APPLIES.  THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH
                  A VIEW TO, OR FOR RESALE IN CONNECTION  WITH, ANY DISTRIBUTION
                  THEREOF  WITHIN THE MEANING OF THE  SECURITIES ACT OF 1933 AND
                  MAY

                                        3

                  NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT
                  IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION
                  REQUIREMENTS OF THE SECURITIES ACT OF 1933."

                  The  undersigned  understands  and agrees that the legends set
forth in  paragraphs  E and F above shall be removed by  delivery of  substitute
certificates  without  such legend if the  undersigned  shall have  delivered to
Associated a copy of a letter from the staff of the Commission, or an opinion of
counsel in form and substance  reasonably  satisfactory  to  Associated,  to the
effect that such legend is not required for purposes of the Act.

                  I further  represent to and covenant  with  Associated  that I
will not,  during the 30 days  prior to the  Effective  Time (as  defined in the
Agreement),  sell,  transfer or  otherwise  dispose of any shares of the Company
Securities  or shares of the capital  stock of  Associated  that I may hold and,
furthermore,  that I will not sell,  transfer or otherwise dispose of any shares
of Associated Securities received by me in the Merger or any other shares of the
capital stock of Associated  until after such time as results  covering at least
30 days of combined operations of the Company and Associated have been published
by  Associated,  in the  form  of a  quarterly  earnings  report,  an  effective
registration statement filed with the Commission,  a report to the Commission on
Form 10-K,  10-Q,  or 8-K,  or any other  public  filing or  announcement  which
includes the combined results of operations.

                  Execution of this letter should not be considered an admission
on my part that I am an  "affiliate"  of the Company as  described  in the first
paragraph of this  letter,  or as a waiver of any rights I may have to object to

First Financial Corporation

Gentlemen:

         I have been  advised that as of the date of this letter I may be deemed
to  be  an  "affiliate"  of  Associated  Banc-Corp.,   a  Wisconsin  corporation
("Associated"),  as  the  term  "affiliate"  is  (i)  defined  for  purposes  of
paragraphs (c) and (d) of Rule 145 of the rules and regulations  (the "Rules and
Regulations") of the Securities and Exchange Commission (the "Commission") under
the Securities Act of 1933, as amended (the "Act"),  and/or (ii) used in and for
purposes  of  Accounting  Series,  Releases  130 and  135,  as  amended,  of the
Commission.  Pursuant  to the terms of the Merger  Agreement  dated as of May14,
1997 (the  "Agreement")  among  Associated,  Badger  Merger  Corp.,  a Wisconsin
corporation  ("Merger  Sub"),  and  First  Financial  Corporation,  a  Wisconsin
corporation (the "Company"), Merger Sub will be merged with and into the Company
(the "Merger").

                  I represent, warrant and covenant to the Company as follows:

         A. I will not make any sale, transfer or other disposition of shares of
     common  stock,  par value $.01 per share,  of Associated  (the  "Associated
     Securities") in violation of the Act or the Rules and Regulations.

         B. I have  carefully  read this letter and the  Agreement and discussed
     the requirements of such documents and other applicable limitations upon my
     ability to sell, transfer or otherwise dispose of Associated Securities, to
     the extent I felt necessary, with my counsel or counsel for Associated.


         I further  represent to and covenant  with the Company that I will not,
during the 30 days prior to the  Effective  Time (as defined in the  Agreement),
sell,  transfer or otherwise dispose of any shares of the Associated  Securities
or shares of the capital stock of Associated  that I may hold and,  furthermore,
that I will not sell,  transfer or otherwise dispose of any shares of Associated
Securities or any other shares of the capital  stock of  Associated  until after
such time as results  covering  at least 30 days of combined  operations  of the
Company and  Associated  have been  published  by  Associated,  in the form of a
quarterly  earnings report, an effective  registration  statement filed with the
Commission, a report to the

<PAGE>


Commission  on  Form  10-K,  10-Q,  or  8-K,  or  any  other  public  filing  or
announcement which includes the combined results of operations.

         Execution of this letter  should not be  considered  an admission on my
part that I am an "affiliate" of Associated as described in the first  paragraph
of this  letter,  or as a waiver of any rights I may have to object to any claim
that I am such an affiliate on or after the date of this letter.


                                                      Very truly yours,


                                                      --------------------------

                           FIRST FINANCIAL CORPORATION
                             STOCK OPTION AGREEMENT



                  STOCK  OPTION  AGREEMENT,  dated  as of May 14,  1997,  by and
between First Financial Corporation, a Wisconsin corporation (the "Issuer"), and
Associated Banc-Corp, a Wisconsin corporation ("Grantee").

                  WHEREAS,  concurrently with the execution and delivery of this
Agreement, Issuer, Grantee, and Badger Merger Corp., a Wisconsin corporation and
a wholly owned subsidiary of Grantee, are entering into an Agreement and Plan of
Merger,  dated as of the date hereof (the "Merger  Agreement"),  which  provides
for, among other things,  upon the terms and subject to the conditions  thereof,
the merger of Merger Sub with and into Issuer (the "Merger");

                  WHEREAS, as a condition to Grantee's willingness to enter into
the Merger Agreement,  Grantee has requested that the Issuer agree, and in order
to induce Grantee to enter into the Merger  Agreement,  Issuer has so agreed, to
grant to Grantee an option with  respect to certain  shares of  Issuer's  common
stock on the terms and subject to the conditions set forth herein; and

                  WHEREAS, as a condition to Issuer's  willingness to enter into
the Merger Agreement,  the Issuer has requested that Grantee agree, and in order
to induce the Issuer to enter into the Merger Agreement,  Grantee has so agreed,
to grant to Issuer an option with respect to certain shares of Grantee's  common
stock on substantially the same terms as set forth herein;

                  NOW,  THEREFORE,  in consideration of the foregoing and of the
mutual covenants,  representations,  warranties and agreements  contained herein
and in the Merger  Agreement;  and  intending to be legally  bound  hereby,  the
parties agree as follows:

                  1.  Grant  of  Option.   Issuer  hereby   grants   Grantee  an
irrevocable  option (the "Stock Option") to purchase up to (a) 7,245,877  shares
(the "Option Shares") of common stock, $1.00 par value per share, of Issuer (the
"Issuer Common Stock") or (b) if, immediately prior to exercise,  such number of
shares of Issuer  Common Stock is less than 19.9% of the issued and  outstanding
shares of Issuer Common Stock at the time of exercise of the Stock Option,  such
greater  number of shares of Issuer  Common  Stock as equals 19.9% of the issued
and  outstanding  shares of Issuer  Common Stock at such time of exercise of the
Stock  Option,  in the manner set forth  below,  at a price of $ 23.25 per share
(the  "Exercise  Price"),  payable in cash in accordance  with Section 4 hereof.
Capitalized  terms used and not otherwise defined herein shall have the meanings
set forth in the Merger Agreement.

                  2.  Exercise  of  Option.  (a)  Subject to the  provisions  of
Sections 2(c) and (d), the Stock Option may be exercised by Grantee, in whole or
in part, at any time or from time to time following the occurrence of a Purchase
Event (as defined below), provided that, except as provided in the last sentence
of this Section  2(a),  the Stock Option  shall  terminate  and be of no further
force and effect upon the earliest to occur of (i) the Effective  Time,  (ii) 12
months after the first occurrence of


<PAGE>


                                        2

a Purchase  Event and (iii)  termination  of the Merger  Agreement in accordance
with its terms prior to the  occurrence of a Purchase  Event  (provided that the
Stock  Option  shall  not  terminate  for a period of 12  months  following  any
occurrence specified in Sections 2(b)(iv)(A) or 2(b)(v)(A); and provided further
that any  purchase of shares upon  exercise of the Stock Option shall be subject
to compliance  with  applicable  law,  including the Bank Holding Company Act of
1956, as amended (the "BHC Act").  Notwithstanding  the termination of the Stock
Option,  Grantee shall be entitled to purchase the Option Shares with respect to
which it has  exercised  the Stock  Option in  accordance  with the terms hereof
prior to the  termination  of the Stock  Option.  The  termination  of the Stock
Option shall not affect any rights  hereunder which by their terms extend beyond
the date of such termination.

                  (b) As  used  herein,  a  "Purchase  Event"  means  any of the
following events:

                  (i) any  person  (other  than  Grantee  or any  subsidiary  of
         Grantee)  shall have  commenced  (as such term is defined in Rule 14d-2
         under the Exchange Act), or shall have filed a  registration  statement
         under the  Securities  Act with  respect to, a tender offer or exchange
         offer to purchase  any shares of Issuer  Common  Stock such that,  upon
         consummation  of such offer,  such person or a "group" (as such term is
         defined under the Exchange Act) of which such person is a member, would
         acquire beneficial  ownership (as such term is defined in Rule 13d-3 of
         the Exchange Act), or the right to acquire beneficial ownership, of 15%
         or more of the then outstanding  Issuer Common Stock (any such offer, a
         "Tender Offer"),  and the Board of Directors shall not have recommended
         against such tender offer or exchange  offer within 10 business days of
         such  commencement or filing or at any time thereafter  shall recommend
         acceptance thereof;

                  (ii) Issuer or any subsidiary of Issuer shall have authorized,
         recommended,  proposed or publicly announced an intention to authorize,
         recommend or propose,  or entered  into,  an agreement  with any person
         (other  than  Grantee or any  subsidiary  of  Grantee)  to (A) effect a
         merger, consolidation or other business combination involving Issuer or
         any of its  subsidiaries  (other than  internal  mergers,  reorganizing
         actions or  consolidations  involving  only  existing  subsidiaries  of
         Issuer),  (B) sell,  lease or otherwise  dispose of assets of Issuer or
         its subsidiaries  aggregating 15% or more of the  consolidated  assets,
         net revenues or net income of Issuer and its subsidiaries or (C) issue,
         sell  or   otherwise   dispose   of   (including   by  way  of  merger,
         consolidation,  share exchange or any similar  transaction)  securities
         representing  15% or more of the  voting  power of Issuer or any of its
         subsidiaries (any of the foregoing, an "Acquisition Transaction");

                   (iii) any person  (other than  Grantee or any  subsidiary  of
         Grantee)  shall have  acquired  beneficial  ownership  (as such term is
         defined in Rule 13d-3 under the  Exchange  Act) or the right to acquire
         beneficial  ownership of, or any "group" (as such term is defined under
         the Exchange Act) shall have been formed which beneficially owns or has
         the right to acquire  beneficial  ownership of, shares of Issuer Common
         Stock (other than trust account shares)  aggregating 15% or more of the
         then outstanding Issuer Common Stock;

                  (iv) (A) the  holders of Issuer  Common  Stock  shall not have
         approved the Merger Agreement at the meeting of such  shareholders held
         for the  purpose of voting on the Merger  Agreement,  (B) such  meeting
         shall  not  have  been  held or  shall  have  been  cancelled  prior to
         termination of the Merger  Agreement or (C) Issuer's Board of Directors
         shall have withdrawn

                                        3

         or modified in a manner  adverse to Grantee or to Grantee's  ability to
         consummate the  transactions  contemplated by the Merger  Agreement the
         recommendation  of  Issuer's  Board of  Directors  with  respect to the
         Merger Agreement,  in each case after any person (other than Grantee or
         any subsidiary of Grantee) shall have (X) publicly announced,  or taken
         actions which have  resulted in public  disclosure  of, a proposal,  or
         publicly  disclosed an  intention  to make a proposal,  to engage in an
         Acquisition  Transaction  and shall not have withdrawn such proposal at
         least 10 business days prior to the  stockholders'  meeting to consider
         the Merger  (provided  that any public  disclosures  to the effect that
         such person intends to or may make another proposal shall result in the
         original proposal not being deemed to have been withdrawn) or (Y) filed
         an application (or given a notice),  whether in draft or final form, to
         the Federal Reserve Board, the OCC, the FDIC or any other  governmental
         or  regulatory  authority  for  approval  to engage  in an  Acquisition
         Transaction;  provided;  that the Stock Option shall not be exercisable
         upon the occurrence  specified in Section  2(b)(iv)(A) above unless and
         until any of the events  specified  in Section  2(b)(ii) or (iii) above
         shall have occurred; or

                  (v) (A) there  shall  exist a willful  or  intentional  breach
         under the Merger  Agreement  by Issuer and such  breach  would  entitle
         Grantee to  terminate  the Merger  Agreement;  and (B) within 12 months
         from the date of such  breach,  any of the events  specified in Section
         2(b)(ii) or (iii) above shall have occurred.

As used in this Agreement, "person" shall have the meaning specified in Sections
3(a)(9) and 13(d)(3) of the Exchange Act.

                  (c) In the event Grantee  wishes to exercise the Stock Option,
it shall send to Issuer a written  notice (an "Exercise  Notice" and the date of
which being  herein  referred to as a "Notice  Date")  specifying  (i) the total
number of Option  Shares that it intends to purchase  pursuant to such  exercise
and (ii) a place and date not earlier than three business days nor later than 20
business  days from the Notice Date for the closing of such purchase (a "Closing
Date");  provided  that if any closing of the purchase and sale  pursuant to the
Stock Option (a "Closing")  cannot be  consummated  by reason of any  applicable
order, injunction,  decree, judgment, law or regulation, the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which such  restriction  on  consummation  has expired or been  terminated;  and
provided further, without limiting the foregoing,  that if prior notification to
or  approval  of the  Federal  Reserve  Board,  the OCC,  the FDIC or any  other
governmental  or  regulatory  authority  is  required  in  connection  with such
purchase,  Grantee shall promptly file the required  notice or  application  for
approval and shall  expeditiously  process the same (and Issuer shall  cooperate
with Grantee in the filing of any such notice or  application  and the obtaining
of any such approval),  and the period of time that otherwise would run pursuant
to this sentence  shall run instead from the date on which,  as the case may be,
(A) any required  notification period has expired or been terminated or (B) such
approval has been obtained,  and in either event,  any requisite  waiting period
has passed.

                  (d)  Notwithstanding  Section  2(c),  in no  event  shall  any
Closing  Date occur later than 18 months after the related  Notice Date,  and if
such Closing shall not have occurred within 18 months after such Notice Date due
to the failure to obtain any required approval of the Federal Reserve Board, the
OCC, the FDIC or any other governmental or regulatory authority, the exercise of
the Stock Option or Substitute  Option  effected on such date shall be deemed to
have expired. In


<PAGE>


                                        4

the event (i) Grantee receives  official notice that any such approval  required
for the  purchase  of Option  Shares  will not be issued  or  granted  or (ii) a
Closing Date shall not have occurred  within 18 months after the related  Notice
Date due to the failure to obtain any such  approval,  Grantee shall be entitled
to  exercise  its rights to exercise  the Stock  Option in  connection  with the
resale of Issuer  Common Stock or other  securities  pursuant to a  registration
statement as provided in Section 9. The provisions of this Section 2 and Section
4 shall apply with appropriate adjustments to any such exercise.

                  3.  Conditions to Closing.  The  obligation of Issuer to issue
Option  Shares to Grantee  hereunder is subject to the  conditions  that (a) all
consents, approvals, orders or authorizations of, or registrations, declarations
or filings  with,  the Federal  Reserve  Board,  the OCC,  the FDIC or any other
governmental or regulatory  authority,  if any,  required in connection with the
issuance of Option  Shares  hereunder  shall have been  obtained or made, as the
case may be,  and (b) no  order,  injunction  or  decree  issued by any court or
agency of  competent  jurisdiction  or other  legal  restraint  preventing  such
issuance shall be in effect.

                  4. Closing. At any Closing, (a) Issuer will deliver to Grantee
a  certificate  or  certificates  in  definitive   form,  such   certificate  or
certificates  to be registered in the name of Grantee,  Merger Sub or such other
affiliate of Grantee as Grantee shall designate in the Exercise Notice and shall
bear the  legend  set forth in  Section  11,  representing  the number of Option
Shares  designated by Grantee in its Exercise Notice,  which Option Shares shall
be free and clear of all  Liens,  and (b)  Grantee  will  deliver  to Issuer the
aggregate Exercise Price for the Option Shares so designated and being purchased

surviving corporation, but, in connection with such merger, the shares of Issuer
Common Stock  outstanding  immediately  prior to the consummation of such merger
shall be changed into or exchanged  for stock or other  securities  of Issuer or
any other person or cash or any other  property,  or the shares of Issuer Common
Stock  outstanding  immediately  prior to the  consummation of such merger shall
after such merger represent less than 50% of the outstanding  voting  securities
of  the  merged  company,  or  (iii)  to  sell  or  otherwise  transfer  all  or
substantially all of its assets to any person,  other than Grantee or one of its
subsidiaries,  then,  and in  each  such  case,  the  agreement  governing  such
transaction  shall make proper  provisions so that the Stock Option shall,  upon
the  consummation of any such  transaction and upon the terms and conditions set
forth herein,  be converted  into, or exchanged for, an option (the  "Substitute
Option"),  at the election of Grantee,  of either (A) the Acquiring  Corporation
(as defined  below) or (B) any person that  controls the  Acquiring  Corporation
(any such person being referred to as "Substitute Option Issuer").

                  (c) The  Substitute  Option  shall  have the same terms as the
Stock  Option;  provided that the exercise  price  therefor and number of shares
subject  thereto shall be as set forth in this Section 7; provided  further that
the Substitute Option shall be exercisable immediately upon issuance without the
occurrence of a Purchase  Event;  and provided  further that if the terms of the
Substitute  Option cannot,  for legal  reasons,  be the same as the Stock Option
(subject to the  variations  described in the  foregoing  provisos),  such terms
shall be as similar as possible  and in no event less  advantageous  to Grantee.
Substitute  Option  Issuer  shall also enter into an  agreement  with Grantee in
substantially  the  same  form  as this  Agreement  (subject  to the  variations
described  in  the  foregoing  provisos),  which  shall  be  applicable  to  the
Substitute Option.

                  (d) The Substitute Option shall be exercisable for such number
of shares of  Substitute  Common  Stock  (as  defined  below) as is equal to the
Assigned Value (as defined  below)  multiplied by the number of shares of Issuer
Common Stock for which the Stock Option was theretofore exercisable,  divided by
the Average Price (as defined below), rounded up to the nearest whole share. The
exercise  price per share of Substitute  Common Stock of the  Substitute  Option
(the  "Substitute  Option  Price")  shall  then be equal to the  Exercise  Price
multiplied  by a  fraction  in which the  numerator  is the  number of shares of
Issuer Common Stock for which the Stock Option was  theretofore  exercisable and
the denominator is the number of shares of Substitute Common Stock for which the
Substitute Option is exercisable.

                  (e) In no event,  pursuant to any of the foregoing paragraphs,
shall the Substitute  Option be exercisable for more than 19.9% of the aggregate
of the shares of Substitute  Common Stock  outstanding  prior to exercise of the
Substitute  Option. In the event that the Substitute Option would be exercisable
for more than 19.9% of the aggregate of the shares of outstanding Substitute

Common Stock but for the  limitation in the first sentence of this Section 7(e),
Substitute  Option  Issuer  shall make a cash  payment  to Grantee  equal to the
excess of (i) the value of the  Substitute  Option  without giving effect to the
limitation in the first sentence of this Section 7(e) over (ii) the value of the
Substitute Option after giving effect to the limitation in the first sentence of
this Section 7(e).  This difference in value shall be determined by a nationally
recognized investment banking firm selected by Grantee.

                  (f) Issuer shall not enter into any  transaction  described in
Section 7(b) unless the Acquiring  Corporation  and any person that controls the
Acquiring  Corporation assume in writing all the obligations of Issuer hereunder
and take all other actions that may be necessary so that the  provisions of this
Section 7 are given full force and effect (including,  without  limitation,  any
action that may be  necessary  so that the holders of the other shares of common
stock issued by Substitute Option Issuer are not entitled to exercise any rights
by reason of the issuance or exercise of the Substitute Option and the shares of
Substitute  Common Stock are  otherwise in no way  distinguishable  from or have
lesser  economic  value than other shares of common  stock issued by  Substitute
Option Issuer (other than any  diminution in value  resulting from the fact that
the shares of Substitute Common Stock are restricted  securities,  as defined in
Rule 144 under the Securities Act or any successor provision)).

                  (g)  For  purposes  hereof,   the  following  terms  have  the
following meanings:

                  (1)  "Acquiring  Corporation"  means  (i)  the  continuing  or
         surviving  corporation  of a  consolidation  or merger  with Issuer (if
         other  than  Issuer),  (ii)  Issuer in a merger in which  Issuer is the
         continuing or surviving  corporation and (iii) the transferee of all or
         substantially all of Issuer's assets or deposits.

                  (2)  "Assigned  Value"  means the highest of (A) the price per
         share of  Issuer  Common  Stock at which a Tender  Offer  has been made
         after  the  date   hereof  and  prior  to  the   consummation   of  the
         consolidation,  merger or sale  referred  to in Section  7(b),  (B) the
         price per share to be paid by any third party or the  consideration per
         share to be received by holders of Issuer  Common  Stock,  in each case
         pursuant  to  the   agreement   with   Issuer   with   respect  to  the
         consolidation,  merger or sale  referred  to in Section  7(b),  (C) the
         highest closing sales price per share for Issuer Common Stock quoted on
         the National  Association of Securities  Dealers'  Automated  Quotation
         System (the "NASDAQS") or, if the shares of Issuer Common Stock are not
         quoted  thereon,  on the principal  trading market on which such shares
         are traded as  reported by a  recognized  source)  during the  12-month
         period immediately preceding the consolidation, merger or sale referred
         to in Section 7(b) and (D) in the event the transaction  referred to in
         Section 7(b) is a sale of all or  substantially  all of Issuer's assets
         and/or  deposits,  an amount  equal to (i) the sum of the price paid in
         such sale for such assets and/or  deposits and the current market value
         of the  remaining  assets of  Issuer,  as  determined  by a  nationally
         recognized investment banking firm selected by Grantee, divided by (ii)
         the number of shares of Issuer Common Stock  outstanding  at such time.
         In the event that a Tender Offer is made for Issuer  Common Stock or an
         agreement  is  entered  into for a merger  or  consolidation  involving
         consideration  other than cash,  the value of the  securities  or other
         property  issuable or  deliverable  in exchange for Issuer Common Stock
         shall be determined by a nationally  recognized investment banking firm
         selected by Grantee.

                                        8

                  (3) "Average  Price" means the average closing sales price per
         share of a share of Substitute  Common Stock quoted on the NASDAQS (or,
         if the shares of Substitute Common Stock are not quoted thereon, on the
         principal trading market on which such shares are traded as reported by
         a  recognized  source)  for  the one  year  immediately  preceding  the
         consolidation,  merger or sale in question, but in no event higher than
         the closing price of the shares of  Substitute  Common Stock on the day
         preceding  such  consolidation,   merger  or  sale;  provided  that  if
         Substitute Option Issuer is Issuer, the Average Price shall be computed
         with respect to a share of common  stock  issued by Issuer,  the person
         merging into Issuer or by any company which  controls  such person,  as
         Grantee may elect.

                  (4)  "Substitute  Common  Stock"  means the  shares of capital
         stock (or similar equity  interest)  with the greatest  voting power in
         respect of the election of directors (or persons similarly  responsible
         for the direction of the business and affairs) of the Substitute Option
         Issuer.

                  8. Cash-out  Rights.  If and to the extent the Stock Option is
not exercisable with respect to any of the Option Shares due to Article 9 of the
Articles of Incorporation of the Issuer,  Grantee has the right to, and may with
respect  to  such  Option  Shares  which  are  not  exercisable,   in  its  sole
determination,  elect to receive a cash  payment  in an amount  equal to (A) the
amount by which (1) the "Market/Tender  Offer Price" for shares of Issuer Common
Stock as of the date  Grantee  gives notice of its intent to exercise its rights
under this  Section 8 (defined as the higher of (x) the highest  price per share
of Issuer  Common Stock paid as of such date  pursuant to any tender or exchange
offer or other  Acquisition  Proposal  and (y) the average of the  closing  sale
prices of  shares  of  Issuer  Common  Stock on the  NASDAQS  or, if not  quoted
thereon,  the  principal  trading  market on which  such  shares are traded by a
recognized  source  for the 10 trading  days  immediately  preceding  such date)
exceeds (2) the Exercise Price, multiplied by the number of such Option Shares.

                  9.  Registration  Rights.  (a) Issuer  shall,  if requested by
Grantee  at any time and from time to time (a) within  three  years of the first
exercise  of  the  Stock  Option  or (b)  for 30  business  days  following  the
occurrence  of either of the events set forth in clauses (i) and (ii) of Section
2(d),  as  expeditiously  as possible  prepare  and file up to two  registration
statements  under the Securities Act if such  registration is necessary in order
to permit the sale or other  disposition of any or all shares of securities that
have been  acquired  by or are  issuable to Grantee  upon  exercise of the Stock
Option in  accordance  with the  intended  method  of sale or other  disposition
stated by Grantee,  including a "shelf'  registration  statement  under Rule 415
under the  Securities Act or any successor  provision,  and Issuer shall use its
best efforts to qualify  such shares or other  securities  under any  applicable
state securities  laws.  Grantee agrees to use its best efforts to cause, and to
cause any  underwriters of any sale or other  disposition to cause,  any sale or
other disposition  pursuant to such  registration  statement to be effected on a
widely  distributed  basis so that upon  consummation  thereof no  purchaser  or
transferee shall own beneficially more than 4.9% of the then outstanding  voting
power of  Issuer.  Issuer  shall use all  reasonable  efforts to cause each such
registration statement to become effective, to obtain all consents or waivers of
other  parties  which  are  required  therefor  and to  keep  such  registration
statement  effective for such period not in excess of 180 days from the day such
registration statement first becomes effective as may be reasonably necessary to
effect such sale or other disposition.  Any registration  statement prepared and
filed under this Section 9, and any sale covered  thereby,  shall be at Issuer's
expense except for underwriting discounts or commissions,  brokers' fees and the
fees and disbursements of Grantee's counsel related thereto.

                                        9


                  (b) In the  event  that  Grantee  requests  Issuer  to  file a
registration  statement  following the failure to obtain a required approval for
an exercise of the Stock Option as described in Section 2(d), the closing of the
sale or other disposition of Issuer Common Stock or other securities pursuant to
such registration  statement shall occur  substantially  simultaneously with the
exercise of the Stock Option.

                  (c) The  obligations  of Issuer under this Section 9 to file a
registration  statement and to maintain its  effectiveness  may be suspended for
one or more periods of time not  exceeding 60 days in the aggregate if the Board
of  Directors  of  Issuer  shall  have   determined  that  the  filing  of  such
registration  statement or the  maintenance of its  effectiveness  would require
premature  disclosure  of  nonpublic   information  that  would  materially  and
adversely affect Issuer.

                  (d) If  during  the  time  periods  referred  to in the  first
sentence of Section 9(a) Issuer effects a registration  under the Securities Act
of Issuer  Common  Stock for its own  account or for any other  stockholders  of
Issuer (other than on Form S-4 or Form S-8, or any successor form), Issuer shall
allow  Grantee  the  right  to  participate  in  such  registration,   and  such
participation   shall  not  affect  the  obligation  of  Issuer  to  effect  two
registration statements for Grantee under this Section 10; provided that, if the
managing  underwriters  of such offering  advise Issuer in writing that in their
opinion the number of shares of Issuer Common Stock  requested to be included in
such registration exceeds the number which can be sold in such offering,  Issuer
shall  include the shares  requested to be included  therein by Grantee pro rata
with the shares intended to be included therein by Issuer.

                  (e) Grantee shall provide all information reasonably requested
by Issuer for inclusion in any registration statement to be filed hereunder.  In
connection with any registration  pursuant to this Section 9, Issuer and Grantee
shall  provide each other and any  underwriter  of the offering  with  customary
representations,  warranties,  covenants,  indemnification  and  contribution in
connection with such registration.

                  10. Restrictive Legends. Each certificate  representing Option
Shares issued to Grantee  hereunder shall initially be endorsed with a legend in
substantially the following form:

                  THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE HAVE NOT BEEN
         REGISTERED  UNDER THE  SECURITIES  ACT OF 1933, AS AMENDED,  AND MAY BE
         REOFFERED OR SOLD ONLY IF SO  REGISTERED  OR IF AN EXEMPTION  FROM SUCH
         REGISTRATION AND APPLICABLE  STATE  SECURITIES LAWS IS AVAILABLE.  SUCH
         SECURITIES ARE ALSO SUBJECT TO ADDITIONAL  RESTRICTIONS  ON TRANSFER AS
         SET FORTH IN THE STOCK OPTION AGREEMENT,  DATED MAY 14, 1997, A COPY OF
         WHICH MAY BE OBTAINED FROM THE ISSUER HEREOF.

                  11.  NASDAQS  Listing.  Upon any exercise of the Stock Option,
Issuer shall use its best efforts to cause the shares of Issuer  Common Stock to
be acquired in connection  with such exercise of the Stock Option to be approved
for  listing on the  NASDAQS  and each other  securities  exchange on which such
shares are listed as soon as practicable after such exercise.

                  12. Assignment;  Third Party  Beneficiaries.  (a) Neither this
Agreement nor any of the rights, interests or obligations of any party hereunder
shall be assigned by any of the parties


<PAGE>


                                       10

hereto (whether by operation of law or otherwise)  without prior written consent
of the other  party;  provided  that  Grantee  may assign all or any part of its
rights  hereunder  to (i) any  affiliate  thereof or (ii) any  person  after the
occurrence  of a  Purchase  Event.  Subject  to  the  preceding  sentence,  this
Agreement  will be binding upon,  inure to the benefit of and be  enforceable by
the  parties  and  their  respective  successors  and  assigns.  This  Agreement
(including the documents and instruments  referred to herein) is not intended to
confer  upon any person  other than the  parties  hereto any rights or  remedies
hereunder.

                  (b) Any Option Shares sold by a party in  compliance  with the
provisions of Section 9 shall,  upon  consummation  of such sale, be free of the
restrictions imposed with respect to such shares by this Agreement.  In no event
will any  transferee  of any Option  Shares be entitled to the rights of Grantee
hereunder.

                  (c)  Certificates  representing  shares  sold in a  registered
public  offering  pursuant to Section 9 shall not be required to bear the legend
set forth in Section 10.

                  13.  Enforcement  of the  Agreement.  The parties hereto agree
that  irreparable  damage would occur in the event that any of the provisions of
this  Agreement  were not performed in accordance  with their  specific terms or
were  otherwise  breached.  It is  accordingly  agreed that the parties shall be
entitled to an injunction or injunctions  to prevent  breaches of this Agreement
and to enforce  specifically the terms and provisions hereof in any court of the
United  States or any state having  jurisdiction,  this being in addition to any
other remedy to which they are entitled at law or in equity.

                  14. Entire Agreement.  This Agreement and the Merger Agreement
(together  with the other  documents and  instruments  referred to in the Merger
Agreement)  constitute the entire  agreement and supersede all prior  agreements
and understandings, both written and oral, among the parties with respect to the
subject matter hereof.

                  15.  Further  Assurances.  Each party will execute and deliver
all such further  documents and  instruments and take all such further action as
may be necessary in order to consummate the transactions contemplated hereby.

                  16.  Severability.  Any term or  provision  of this  Agreement
which  is  invalid  or  unenforceable  in any  jurisdiction  shall,  as to  that
jurisdiction,   be   ineffective   to  the   extent   of  such   invalidity   or
unenforceability  without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or  enforceability of
any of the terms or provisions of this Agreement in any other  jurisdiction.  If
any  provision  of  this  Agreement  is so  broad  as to be  unenforceable,  the
provision shall be interpreted to be only so broad as is enforceable.

                  17. Notices.  All notices and other  communications  hereunder
shall be in writing and shall be deemed given if delivered personally, mailed by
registered or certified mail (return

                             STOCK OPTION AGREEMENT


                  STOCK  OPTION  AGREEMENT,  dated  as of May 14,  1997,  by and
between Associated Bank-Corp, a Wisconsin corporation (the "Issuer"),  and First
Financial Corporation, a Wisconsin corporation ("Grantee").

                  WHEREAS,  concurrently with the execution and delivery of this
Agreement,  Issuer,  Badger Merger Corp., a Wisconsin  corporation  and a wholly
owned  subsidiary  of Issuer  ("Merger  Sub"),  and Grantee are entering into an
Agreement  and  Plan  of  Merger,  dated  as of the  date  hereof  (the  "Merger
Agreement"),  which provides for, among other things, upon the terms and subject
to the conditions  thereof,  the merger of Merger Sub with and into Grantee (the
"Merger");

                  WHEREAS, as a condition to Grantee's willingness to enter into
the Merger Agreement,  Grantee has requested that the Issuer agree, and in order
to induce Grantee to enter into the Merger  Agreement,  Issuer has so agreed, to
grant to Grantee an option with  respect to certain  shares of  Issuer's  common
stock on the terms and subject to the conditions set forth herein; and

                  WHEREAS, as a condition to Issuer's  willingness to enter into
the Merger Agreement,  the Issuer has requested that Grantee agree, and in order
to induce the Issuer to enter into the Merger Agreement,  Grantee has so agreed,
to grant to Issuer an option with respect to certain shares of Grantee's  common
stock on substantially the same terms as set forth herein;

                  NOW,  THEREFORE,  in consideration of the foregoing and of the
mutual covenants,  representations,  warranties and agreements  contained herein
and in the Merger  Agreement;  and  intending to be legally  bound  hereby,  the
parties agree as follows:

                  1.  Grant  of  Option.   Issuer  hereby   grants   Grantee  an
irrevocable  option (the "Stock Option") to purchase up to (a) 4,465,361  shares
(the "Option Shares") of common stock, $0.01 par value per share, of Issuer (the
"Issuer Common Stock") or (b) if, immediately prior to exercise,  such number of
shares of Issuer  Common Stock is less than 19.9% of the issued and  outstanding
shares of Issuer Common Stock at the time of exercise of the Stock Option,  such
greater  number of shares of Issuer  Common  Stock as equals 19.9% of the issued
and  outstanding  shares of Issuer  Common Stock at such time of exercise of the
Stock Option, in the manner set forth below, at a price of $32.50 per share (the
"Exercise  Price"),  payable  in cash  in  accordance  with  Section  4  hereof.
Capitalized  terms used and not otherwise defined herein shall have the meanings
set forth in the Merger Agreement.

                  2.  Exercise  of  Option.  (a)  Subject to the  provisions  of
Sections 2(c) and (d), the Stock Option may be exercised by Grantee, in whole or
in part, at any time or from time to time following the occurrence of a Purchase
Event (as defined below), provided that, except as provided in the last sentence
of this Section  2(a),  the Stock Option  shall  terminate  and be of no further
force and effect upon the earliest to occur of (i) the Effective  Time,  (ii) 12
months after the first occurrence of

                                        2

a Purchase  Event and (iii)  termination  of the Merger  Agreement in accordance
with its terms prior to the  occurrence of a Purchase  Event  (provided that the
Stock  Option  shall  not  terminate  for a period of 12  months  following  any
occurrence specified in Sections 2(b)(iv)(A) or 2(b)(v)(A); and provided further
that any  purchase of shares upon  exercise of the Stock Option shall be subject
to compliance  with  applicable  law,  including the Bank Holding Company Act of
1956, as amended (the "BHC Act").  Notwithstanding  the termination of the Stock
Option,  Grantee shall be entitled to purchase the Option Shares with respect to
which it has  exercised  the Stock  Option in  accordance  with the terms hereof
prior to the  termination  of the Stock  Option.  The  termination  of the Stock
Option shall not affect any rights  hereunder which by their terms extend beyond
the date of such termination.

                  (b) As  used  herein,  a  "Purchase  Event"  means  any of the
following events:

                  (i) any  person  (other  than  Grantee  or any  subsidiary  of
         Grantee)  shall have  commenced  (as such term is defined in Rule 14d-2
         under the Exchange Act), or shall have filed a  registration  statement
         under the  Securities  Act with  respect to, a tender offer or exchange
         offer to purchase  any shares of Issuer  Common  Stock such that,  upon
         consummation  of such offer,  such person or a "group" (as such term is
         defined under the Exchange Act) of which such person is a member, would
         acquire beneficial  ownership (as such term is defined in Rule 13d-3 of
         the Exchange Act), or the right to acquire beneficial ownership, of 15%
         or more of the then outstanding  Issuer Common Stock (any such offer, a
         "Tender Offer"),  and the Board of Directors shall not have recommended
         against such tender offer or exchange  offer within 10 business days of
         such  commencement or filing or at any time thereafter  shall recommend
         acceptance thereof;

                  (ii) Issuer or any subsidiary of Issuer shall have authorized,
         recommended,  proposed or publicly announced an intention to authorize,
         recommend or propose,  or entered  into,  an agreement  with any person
         (other  than  Grantee or any  subsidiary  of  Grantee)  to (A) effect a
         merger, consolidation or other business combination involving Issuer or
         any of its  subsidiaries  (other than  internal  mergers,  reorganizing
         actions or  consolidations  involving  only  existing  subsidiaries  of
         Issuer),  (B) sell,  lease or otherwise  dispose of assets of Issuer or
         its subsidiaries  aggregating 15% or more of the  consolidated  assets,
         net revenues or net income of Issuer and its subsidiaries or (C) issue,
         sell  or   otherwise   dispose   of   (including   by  way  of  merger,
         consolidation,  share exchange or any similar  transaction)  securities
         representing  15% or more of the  voting  power of Issuer or any of its
         subsidiaries (any of the foregoing, an "Acquisition Transaction");

                   (iii) any person  (other than  Grantee or any  subsidiary  of
         Grantee)  shall have  acquired  beneficial  ownership  (as such term is
         defined in Rule 13d-3 under the  Exchange  Act) or the right to acquire
         beneficial  ownership of, or any "group" (as such term is defined under
         the Exchange Act) shall have been formed which beneficially owns or has
         the right to acquire  beneficial  ownership of, shares of Issuer Common
         Stock (other than trust account shares)  aggregating 15% or more of the
         then outstanding Issuer Common Stock;

                  (iv) (A) the  holders of Issuer  Common  Stock  shall not have
         approved  the  increase  in the number of  authorized  shares of Issuer
         Common Stock or the issuance of Issuer Common Stock in connection  with
         the Merger at the meeting of such  shareholders held for the purpose of
         voting on the  increase  in the number of  authorized  shares of Issuer
         Common

         Stock and the issuance of Issuer  Common Stock in  connection  with the
         Merger,  (B) such  meeting  shall not have been held or shall have been
         cancelled prior to termination of the Merger  Agreement or (C) Issuer's
         Board of Directors shall have withdrawn or modified in a manner adverse
         to  Grantee or to  Grantee's  ability to  consummate  the  transactions
         contemplated  by the Merger  Agreement the  recommendation  of Issuer's
         Board of Directors with respect to the Merger  Agreement,  in each case
         after any person  (other  than  Grantee or any  subsidiary  of Grantee)
         shall have (X) publicly announced, or taken actions which have resulted
         in public disclosure of, a proposal, or publicly disclosed an intention
         to make a proposal,  to engage in an Acquisition  Transaction and shall
         not have withdrawn such proposal at least 10 business days prior to the
         stockholders'  meeting  to  consider  the  increase  in the  number  of
         authorized  shares of Issuer  Common  Stock or the  issuance  of Issuer
         Common Stock in connection  with the Merger  (provided  that any public
         disclosures  to the  effect  that such  person  intends  to or may make
         another proposal shall result in the original proposal not being deemed
         to have  been  withdrawn)  or (Y)  filed  an  application  (or  given a
         notice),  whether in draft or final form, to the Federal Reserve Board,
         the OCC, the FDIC or any other governmental or regulatory authority for
         approval to engage in an  Acquisition  Transaction;  provided  that the
         Stock Option shall not be exercisable upon the occurrence  specified in
         Section  2(b)(iv)(A) above unless and until any of the events specified
         in Section 2 (b)(ii) or (iii) above shall have occurred; or

                  (v) (A) there  shall  exist a willful  or  intentional  breach
         under the Merger  Agreement  by Issuer and such  breach  would  entitle
         Grantee to  terminate  the Merger  Agreement;  and (B) within 12 months
         from the date of such  breach,  any of the events  specified in Section
         2(b)(ii) or (iii) above shall have occurred.

As used in this Agreement, "person" shall have the meaning specified in Sections
3(a)(9) and 13(d)(3) of the Exchange Act.

                  (c) In the event Grantee  wishes to exercise the Stock Option,
it shall send to Issuer a written  notice (an "Exercise  Notice" and the date of
which being  herein  referred to as a "Notice  Date")  specifying  (i) the total
number of Option  Shares that it intends to purchase  pursuant to such  exercise
and (ii) a place and date not earlier than three business days nor later than 20
business  days from the Notice Date for the closing of such purchase (a "Closing
Date");  provided  that if any closing of the purchase and sale  pursuant to the
Stock Option (a "Closing")  cannot be  consummated  by reason of any  applicable
order, injunction,  decree, judgment, law or regulation, the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which such  restriction  on  consummation  has expired or been  terminated;  and
provided further, without limiting the foregoing,  that if prior notification to
or  approval  of the  Federal  Reserve  Board,  the OCC,  the FDIC or any  other
governmental  or  regulatory  authority  is  required  in  connection  with such
purchase,  Grantee shall promptly file the required  notice or  application  for
approval and shall  expeditiously  process the same (and Issuer shall  cooperate
with Grantee in the filing of any such notice or  application  and the obtaining
of any such approval),  and the period of time that otherwise would run pursuant
to this sentence  shall run instead from the date on which,  as the case may be,
(A) any required  notification period has expired or been terminated or (B) such
approval has been obtained,  and in either event,  any requisite  waiting period
has passed.

                                        4

                  (d)  Notwithstanding  Section  2(c),  in no  event  shall  any
Closing  Date occur later than 18 months after the related  Notice Date,  and if
such Closing shall not have occurred within 18 months after such Notice Date due
to the failure to obtain any required approval of the Federal Reserve Board, the
OCC, the FDIC or any other governmental or regulatory authority, the exercise of
the Stock Option or Substitute  Option  effected on such date shall be deemed to
have expired.  In the event (i) Grantee  receives  official notice that any such
approval  required  for the  purchase  of  Option  Shares  will not be issued or
granted or (ii) a Closing  Date shall not have  occurred  within 18 months after
the related Notice Date due to the failure to obtain any such approval,  Grantee
shall be  entitled  to  exercise  its  rights to  exercise  the Stock  Option in
connection with the resale of Issuer Common Stock or other  securities  pursuant
to a  registration  statement as provided in Section 8. The  provisions  of this
Section 2 and Section 4 shall  apply with  appropriate  adjustments  to any such
exercise.

                  3.  Conditions to Closing.  The  obligation of Issuer to issue
Option  Shares to Grantee  hereunder is subject to the  conditions  that (a) all
consents, approvals, orders or authorizations of, or registrations, declarations
or filings  with,  the Federal  Reserve  Board,  the OCC,  the FDIC or any other
governmental or regulatory  authority,  if any,  required in connection with the
issuance of Option  Shares  hereunder  shall have been  obtained or made, as the
case may be,  and (b) no  order,  injunction  or  decree  issued by any court or
agency of  competent  jurisdiction  or other  legal  restraint  preventing  such
issuance shall be in effect.

                  4. Closing. At any Closing, (a) Issuer will deliver to Grantee
a  certificate  or  certificates  in  definitive   form,  such   certificate  or
certificates to be registered in the name of Grantee, or such other affiliate of
Grantee as Grantee  shall  designate in the  Exercise  Notice and shall bear the
legend  set forth in  Section  11,  representing  the  number  of Option  Shares
designated by Grantee in its Exercise Notice,  which Option Shares shall be free
and clear of all Liens,  and (b) Grantee  will  deliver to Issuer the  aggregate
Exercise Price for the Option Shares so designated  and being  purchased at such
Closing  by wire  transfer  of  immediately  available  funds to a bank  account
designated by Issuer.

                  5. Representations and Warranties of Issuer. Issuer represents
and warrants to Grantee that (a) Issuer is a corporation duly organized, validly
existing and in good  standing  under the laws of the State of Wisconsin and has
full  corporate  power and authority to execute and deliver this  Agreement and,
subject to any  approvals  referred to herein,  to consummate  the  transactions
contemplated hereunder, (b) the execution and delivery of this Agreement and the

execution  and  delivery  by Grantee)  this  Agreement  constitutes  a valid and
binding obligation of Issuer,  enforceable against Issuer in accordance with its
terms,  except as  enforcement  may be limited by general  principles  of equity
whether  applied in a court of law or equity and by  bankruptcy,  insolvency and
similar laws affecting creditors' rights and remedies generally,  (d) Issuer has
taken all necessary  corporate  action to authorize and reserve for issuance and
to permit it to issue, upon exercise of the Stock Option,  and at all times from
the date  hereof  through  the  expiration  of the  Stock  Option  will  have so
reserved,  the  requisite  number of  unissued  shares of  Issuer  Common  Stock
necessary to permit  exercise in full of the Stock  Option,  all of which,  upon
their issuance and delivery in accordance with the terms of this Agreement, will

by which it or any of its  assets  or  properties  is bound or  affected  or (3)

to any rights of termination,  amendment,  acceleration  or cancellation  of, or
result in the  creation  of any Lien on any of the  property or assets of Issuer
pursuant to, any note, bond, mortgage,  indenture,  contract,  agreement, lease,
license,  or  other  instrument  or  obligation  to which  Issuer  or any of its
subsidiaries is a party or by which Issuer or any of its assets or properties is
bound  or  affected  (except,  in the case of  clauses  (2) and (3)  above,  for
violations,  breaches  or  defaults  which  would  not,  individually  or in the
aggregate,  have a Material  Adverse Effect on Issuer) and (g) any provisions of
the Wisconsin  Business  Corporation Law or Issuer's  Articles of  Incorporation
prohibiting certain business  combinations shall not apply to Grantee in respect
of  Grantee's  acquisition  of some or all of the Option  Shares and (h) Grantee
will not, as a result of its exercise of the Stock Option, become subject to any
anti-takeover provisions, plans or arrangements in place at Issuer.

                  6.   Representations   and  Warranties  of  Grantee.   Grantee
represents  and  warrants  to Issuer  that (a)  Grantee  is a  corporation  duly

principles  of  equity  whether  applied  in a  court  of law or  equity  and by
bankruptcy, insolvency and similar laws affecting creditors' rights and remedies
generally, (d) the execution and delivery of this Agreement by Grantee does not,
and the  performance  of this  Agreement  by Grantee  will not (1)  violate  the

                                        6


                  7.  Adjustment  upon  Changes  in  Capitalization;  Substitute
Option.  (a) In the event of any  change in Issuer  Common  Stock by reason of a
stock dividend, split-up,  recapitalization,  combination, exchange of shares or
similar transaction,  the type and number of shares or securities subject to the
Stock Option, and the Exercise Price therefor,  shall be adjusted appropriately,
and proper provision shall be made in the agreements governing such transaction,
so that Grantee  shall  receive upon exercise of the Stock Option the number and
class of shares or other securities or property that Grantee would have received
in  respect  of Issuer  Common  Stock if the  Stock  Option  had been  exercised
immediately prior to such event or the record date therefor, as applicable.

                  (b) In the event that Issuer shall enter into an agreement (i)
to consolidate  with or merge into any person,  other than Grantee or one of its
subsidiaries,  and shall not be the continuing or surviving  corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one of
its  subsidiaries,  to merge into Issuer and Issuer shall be the  continuing  or
surviving corporation, but, in connection with such merger, the shares of Issuer
Common Stock  outstanding  immediately  prior to the consummation of such merger
shall be changed into or exchanged  for stock or other  securities  of Issuer or
any other person or cash or any other  property,  or the shares of Issuer Common
Stock  outstanding  immediately  prior to the  consummation of such merger shall
after such merger represent less than 50% of the outstanding  voting  securities
of  the  merged  company,  or  (iii)  to  sell  or  otherwise  transfer  all  or
substantially all of its assets to any person,  other than Grantee or one of its
subsidiaries,  then,  and in  each  such  case,  the  agreement  governing  such
transaction  shall make proper  provisions so that the Stock Option shall,  upon
the  consummation of any such  transaction and upon the terms and conditions set
forth herein,  be converted  into, or exchanged for, an option (the  "Substitute
Option"),  at the election of Grantee,  of either (A) the Acquiring  Corporation
(as defined  below) or (B) any person that  controls the  Acquiring  Corporation
(any such person being referred to as "Substitute Option Issuer").

                  (c) The  Substitute  Option  shall  have the same terms as the
Stock  Option;  provided that the exercise  price  therefor and number of shares
subject  thereto shall be as set forth in this Section 7; provided  further that
the Substitute Option shall be exercisable immediately upon issuance without the
occurrence of a Purchase  Event;  and provided  further that if the terms of the
Substitute  Option cannot,  for legal  reasons,  be the same as the Stock Option
(subject to the  variations  described in the  foregoing  provisos),  such terms
shall be as similar as possible  and in no event less  advantageous  to Grantee.
Substitute  Option  Issuer  shall also enter into an  agreement  with Grantee in
substantially  the  same  form  as this  Agreement  (subject  to the  variations
described  in  the  foregoing  provisos),  which  shall  be  applicable  to  the
Substitute Option.

                  (d) The Substitute Option shall be exercisable for such number
of shares of  Substitute  Common  Stock  (as  defined  below) as is equal to the
Assigned Value (as defined  below)  multiplied by the number of shares of Issuer
Common Stock for which the Stock Option was theretofore exercisable,  divided by
the Average Price (as defined below), rounded up to the nearest whole share. The
exercise  price per share of Substitute  Common Stock of the  Substitute  Option
(the  "Substitute  Option  Price")  shall  then be equal to the  Exercise  Price
multiplied  by a  fraction  in which the  numerator  is the  number of shares of
Issuer Common Stock for which the Stock Option was  theretofore  exercisable and
the denominator is the number of shares of Substitute Common Stock for which the
Substitute Option is exercisable.

                                        7

                  (e) In no event,  pursuant to any of the foregoing paragraphs,
shall the Substitute  Option be exercisable for more than 19.9% of the aggregate
of the shares of Substitute  Common Stock  outstanding  prior to exercise of the
Substitute  Option. In the event that the Substitute Option would be exercisable
for more than 19.9% of the  aggregate  of the shares of  outstanding  Substitute
Common Stock but for the  limitation in the first sentence of this Section 7(e),
Substitute  Option  Issuer  shall make a cash  payment  to Grantee  equal to the
excess of (i) the value of the  Substitute  Option  without giving effect to the
limitation in the first sentence of this Section 7(e) over (ii) the value of the
Substitute Option after giving effect to the limitation in the first sentence of
this Section 7(e).  This difference in value shall be determined by a nationally
recognized investment banking firm selected by Grantee.

                  (f) Issuer shall not enter into any  transaction  described in
Section 7(b) unless the Acquiring  Corporation  and any person that controls the
Acquiring  Corporation assume in writing all the obligations of Issuer hereunder
and take all other actions that may be necessary so that the  provisions of this
Section 7 are given full force and effect (including,  without  limitation,  any
action that may be  necessary  so that the holders of the other shares of common
stock issued by Substitute Option Issuer are not entitled to exercise any rights
by reason of the issuance or exercise of the Substitute Option and the shares of
Substitute  Common Stock are  otherwise in no way  distinguishable  from or have
lesser  economic  value than other shares of common  stock issued by  Substitute
Option Issuer (other than any  diminution in value  resulting from the fact that
the shares of Substitute Common Stock are restricted  securities,  as defined in
Rule 144 under the Securities Act or any successor provision)).

                  (g)  For  purposes  hereof,   the  following  terms  have  the
following meanings:

                  (1)  "Acquiring  Corporation"  means  (i)  the  continuing  or
         surviving  corporation  of a  consolidation  or merger  with Issuer (if
         other  than  Issuer),  (ii)  Issuer in a merger in which  Issuer is the
         continuing or surviving  corporation and (iii) the transferee of all or
         substantially all of Issuer's assets or deposits.

                  (2)  "Assigned  Value"  means the highest of (A) the price per
         share of  Issuer  Common  Stock at which a Tender  Offer  has been made
         after  the  date   hereof  and  prior  to  the   consummation   of  the
         consolidation,  merger or sale  referred  to in Section  7(b),  (B) the
         price per share to be paid by any third party or the  consideration per
         share to be received by holders of Issuer  Common  Stock,  in each case
         pursuant  to  the   agreement   with   Issuer   with   respect  to  the
         consolidation,  merger or sale  referred  to in Section  7(b),  (C) the
         highest closing sales price per share for Issuer Common Stock quoted on
         the National  Association of Securities  Dealers'  Automated  Quotation
         System (the  "NASDAQS")  (or, if the shares of Issuer  Common Stock are
         not  quoted  thereon,  on the  principal  trading  market on which such
         shares  are  traded as  reported  by a  recognized  source)  during the
         12-month period immediately preceding the consolidation, merger or sale
         referred  to in  Section  7(b)  and (D) in the  event  the  transaction
         referred to in Section  7(b) is a sale of all or  substantially  all of
         Issuer's assets and/or deposits,  an amount equal to (i) the sum of the
         price paid in such sale for such assets and/or deposits and the current
         market value of the  remaining  assets of Issuer,  as  determined  by a
         nationally  recognized  investment  banking  firm  selected by Grantee,
         divided by (ii) the number of shares of Issuer Common Stock outstanding
         at such  time.  In the  event  that a Tender  Offer is made for  Issuer
         Common Stock or an agreement is entered into for a merger

                                        8

         or consolidation  involving consideration other than cash, the value of
         the  securities or other  property  issuable or deliverable in exchange
         for Issuer Common Stock shall be determined by a nationally  recognized
         investment banking firm selected by Grantee.

                  (3) "Average  Price" means the average closing sales price per
         share of a share of Substitute  Common Stock quoted on the NASDAQS (or,
         if the shares of Substitute Common Stock are not quoted thereon, on the
         principal trading market on which such shares are traded as reported by
         a  recognized  source)  for  the one  year  immediately  preceding  the
         consolidation,  merger or sale in question, but in no event higher than
         the closing price of the shares of  Substitute  Common Stock on the day
         preceding  such  consolidation,   merger  or  sale;  provided  that  if
         Substitute Option Issuer is Issuer, the Average Price shall be computed
         with respect to a share of common  stock  issued by Issuer,  the person
         merging into Issuer or by any company which  controls  such person,  as
         Grantee may elect.

                  (4)  "Substitute  Common  Stock"  means the  shares of capital
         stock (or similar equity  interest)  with the greatest  voting power in
         respect of the election of directors (or persons similarly  responsible
         for the direction of the business and affairs) of the Substitute Option
         Issuer.

                  8.  Registration  Rights.  (a) Issuer  shall,  if requested by
Grantee  at any time and from time to time (a) within  three  years of the first
exercise  of  the  Stock  Option  or (b)  for 30  business  days  following  the
occurrence  of either of the events set forth in clauses (i) and (ii) of Section
2(d),  as  expeditiously  as possible  prepare  and file up to two  registration
statements  under the Securities Act if such  registration is necessary in order
to permit the sale or other  disposition of any or all shares of securities that
have been  acquired  by or are  issuable to Grantee  upon  exercise of the Stock
Option in  accordance  with the  intended  method  of sale or other  disposition
stated by Grantee,  including a "shelf'  registration  statement  under Rule 415
under the  Securities Act or any successor  provision,  and Issuer shall use its
best efforts to qualify  such shares or other  securities  under any  applicable
state securities  laws.  Grantee agrees to use its best efforts to cause, and to
cause any  underwriters of any sale or other  disposition to cause,  any sale or
other disposition  pursuant to such  registration  statement to be effected on a
widely  distributed  basis so that upon  consummation  thereof no  purchaser  or
transferee shall own beneficially more than 4.9% of the then outstanding  voting
power of  Issuer.  Issuer  shall use all  reasonable  efforts to cause each such
registration statement to become effective, to obtain all consents or waivers of
other  parties  which  are  required  therefor  and to  keep  such  registration
statement  effective for such period not in excess of 180 days from the day such
registration statement first becomes effective as may be reasonably necessary to
effect such sale or other disposition.  Any registration  statement prepared and
filed under this Section 9, and any sale covered  thereby,  shall be at Issuer's
expense except for underwriting discounts or commissions,  brokers' fees and the
fees and disbursements of Grantee's counsel related thereto.

                  (b) In the  event  that  Grantee  requests  Issuer  to  file a
registration  statement  following the failure to obtain a required approval for
an exercise of the Stock Option as described in Section 2(d), the closing of the
sale or other disposition of Issuer Common Stock or other securities pursuant to
such registration  statement shall occur  substantially  simultaneously with the
exercise of the Stock Option.

                                        9

                  (c) The  obligations  of Issuer under this Section 8 to file a
registration  statement and to maintain its  effectiveness  may be suspended for
one or more periods of time not  exceeding 60 days in the aggregate if the Board
of  Directors  of  Issuer  shall  have   determined  that  the  filing  of  such
registration  statement or the  maintenance of its  effectiveness  would require
premature  disclosure  of  nonpublic   information  that  would  materially  and
adversely affect Issuer.

                  (d) If  during  the  time  periods  referred  to in the  first
sentence of Section 8(a) Issuer effects a registration  under the Securities Act
of Issuer  Common  Stock for its own  account or for any other  stockholders  of
Issuer (other than on Form S-4 or Form S-8, or any successor form), Issuer shall
allow  Grantee  the  right  to  participate  in  such  registration,   and  such
participation   shall  not  affect  the  obligation  of  Issuer  to  effect  two
registration statements for Grantee under this Section 8 ; provided that, if the
managing  underwriters  of such offering  advise Issuer in writing that in their
opinion the number of shares of Issuer Common Stock  requested to be included in
such registration exceeds the number which can be sold in such offering,  Issuer
shall  include the shares  requested to be included  therein by Grantee pro rata
with the shares intended to be included therein by Issuer.

                  (e) Grantee shall provide all information reasonably requested
by Issuer for inclusion in any registration statement to be filed hereunder.  In
connection with any registration  pursuant to this Section 8, Issuer and Grantee
shall  provide each other and any  underwriter  of the offering  with  customary
representations,  warranties,  covenants,  indemnification  and  contribution in
connection with such registration.

                  9. Restrictive Legends.  Each certificate  representing Option
Shares issued to Grantee  hereunder shall initially be endorsed with a legend in
substantially the following form:

                  THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE HAVE NOT BEEN
         REGISTERED  UNDER THE  SECURITIES  ACT OF 1933, AS AMENDED,  AND MAY BE
         REOFFERED OR SOLD ONLY IF SO  REGISTERED  OR IF AN EXEMPTION  FROM SUCH
         REGISTRATION AND APPLICABLE  STATE  SECURITIES LAWS IS AVAILABLE.  SUCH
         SECURITIES ARE ALSO SUBJECT TO ADDITIONAL  RESTRICTIONS  ON TRANSFER AS
         SET FORTH IN THE STOCK OPTION AGREEMENT,  DATED MAY 14, 1997, A COPY OF
         WHICH MAY BE OBTAINED FROM THE ISSUER HEREOF.

                  10.  NASDAQS  Listing.  Upon any exercise of the Stock Option,
Issuer shall use its best efforts to cause the shares of Issuer  Common Stock to
be acquired in connection  with such exercise of the Stock Option to be approved
for  listing on the  NASDAQS  and each other  securities  exchange on which such
shares are listed as soon as practicable after such exercise.

                  11. Assignment;  Third Party  Beneficiaries.  (a) Neither this
Agreement nor any of the rights, interests or obligations of any party hereunder
shall be assigned by any of the parties  hereto  (whether by operation of law or
otherwise)  without  prior  written  consent of the other party;  provided  that
Grantee may assign all or any part of its rights  hereunder to (i) any affiliate
thereof or (ii) any person after the occurrence of a Purchase Event.  Subject to
the  preceding  sentence,  this  Agreement  will be binding  upon,  inure to the
benefit of and be enforceable by the parties and their respective successors and
assigns. This Agreement (including the documents and instruments referred


<PAGE>


                                       10

to herein) is not  intended  to confer  upon any person  other than the  parties
hereto any rights or remedies hereunder.

                  (b) Any Option Shares sold by a party in  compliance  with the
provisions of Section 9 shall,  upon  consummation  of such sale, be free of the
restrictions imposed with respect to such shares by this Agreement.  In no event
will any  transferee  of any Option  Shares be entitled to the rights of Grantee
hereunder.

                  (c)  Certificates  representing  shares  sold in a  registered
public  offering  pursuant to Section 8 shall not be required to bear the legend
set forth in Section 9.

                  12.  Enforcement  of the  Agreement.  The parties hereto agree
that  irreparable  damage would occur in the event that any of the provisions of
this  Agreement  were not performed in accordance  with their  specific terms or
were  otherwise  breached.  It is  accordingly  agreed that the parties shall be
entitled to an injunction or injunctions  to prevent  breaches of this Agreement
and to enforce  specifically the terms and provisions hereof in any court of the
United  States or any state having  jurisdiction,  this being in addition to any
other remedy to which they are entitled at law or in equity.

                  13. Entire Agreement.  This Agreement and the Merger Agreement
(together  with the other  documents and  instruments  referred to in the Merger
Agreement)  constitute the entire  agreement and supersede all prior  agreements
and understandings, both written and oral, among the parties with respect to the
subject matter hereof.

                  14.  Further  Assurances.  Each party will execute and deliver
all such further  documents and  instruments and take all such further action as
may be necessary in order to consummate the transactions contemplated hereby.

                  15.  Severability.  Any term or  provision  of this  Agreement
which  is  invalid  or  unenforceable  in any  jurisdiction  shall,  as to  that
jurisdiction,   be   ineffective   to  the   extent   of  such   invalidity   or
unenforceability  without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or  enforceability of
any of the terms or provisions of this Agreement in any other  jurisdiction.  If
any  provision  of  this  Agreement  is so  broad  as to be  unenforceable,  the
provision shall be interpreted to be only so broad as is enforceable.

                  16. Notices.  All notices and other  communications  hereunder
shall be in writing and shall be deemed given if delivered personally, mailed by
registered or certified mail (return receipt  requested) or delivered by express
courier (with  confirmation) to the parties at the following  addresses (or such

                           FIRST FINANCIAL CORPORATION
                             STOCK OPTION AGREEMENT



                  STOCK  OPTION  AGREEMENT,  dated  as of May 14,  1997,  by and
between First Financial Corporation, a Wisconsin corporation (the "Issuer"), and
Associated Banc-Corp, a Wisconsin corporation ("Grantee").

                  WHEREAS,  concurrently with the execution and delivery of this
Agreement, Issuer, Grantee, and Badger Merger Corp., a Wisconsin corporation and
a wholly owned subsidiary of Grantee, are entering into an Agreement and Plan of
Merger,  dated as of the date hereof (the "Merger  Agreement"),  which  provides
for, among other things,  upon the terms and subject to the conditions  thereof,
the merger of Merger Sub with and into Issuer (the "Merger");

                  WHEREAS, as a condition to Grantee's willingness to enter into
the Merger Agreement,  Grantee has requested that the Issuer agree, and in order
to induce Grantee to enter into the Merger  Agreement,  Issuer has so agreed, to
grant to Grantee an option with  respect to certain  shares of  Issuer's  common
stock on the terms and subject to the conditions set forth herein; and

                  WHEREAS, as a condition to Issuer's  willingness to enter into
the Merger Agreement,  the Issuer has requested that Grantee agree, and in order
to induce the Issuer to enter into the Merger Agreement,  Grantee has so agreed,
to grant to Issuer an option with respect to certain shares of Grantee's  common
stock on substantially the same terms as set forth herein;

                  NOW,  THEREFORE,  in consideration of the foregoing and of the
mutual covenants,  representations,  warranties and agreements  contained herein
and in the Merger  Agreement;  and  intending to be legally  bound  hereby,  the
parties agree as follows:

                  1.  Grant  of  Option.   Issuer  hereby   grants   Grantee  an
irrevocable  option (the "Stock Option") to purchase up to (a) 7,245,877  shares
(the "Option Shares") of common stock, $1.00 par value per share, of Issuer (the
"Issuer Common Stock") or (b) if, immediately prior to exercise,  such number of
shares of Issuer  Common Stock is less than 19.9% of the issued and  outstanding
shares of Issuer Common Stock at the time of exercise of the Stock Option,  such
greater  number of shares of Issuer  Common  Stock as equals 19.9% of the issued
and  outstanding  shares of Issuer  Common Stock at such time of exercise of the
Stock  Option,  in the manner set forth  below,  at a price of $ 23.25 per share
(the  "Exercise  Price"),  payable in cash in accordance  with Section 4 hereof.
Capitalized  terms used and not otherwise defined herein shall have the meanings
set forth in the Merger Agreement.

                  2.  Exercise  of  Option.  (a)  Subject to the  provisions  of
Sections 2(c) and (d), the Stock Option may be exercised by Grantee, in whole or
in part, at any time or from time to time following the occurrence of a Purchase
Event (as defined below), provided that, except as provided in the last sentence
of this Section  2(a),  the Stock Option  shall  terminate  and be of no further
force and effect upon the earliest to occur of (i) the Effective  Time,  (ii) 12
months after the first occurrence of


<PAGE>


                                        2

a Purchase  Event and (iii)  termination  of the Merger  Agreement in accordance
with its terms prior to the  occurrence of a Purchase  Event  (provided that the
Stock  Option  shall  not  terminate  for a period of 12  months  following  any
occurrence specified in Sections 2(b)(iv)(A) or 2(b)(v)(A); and provided further
that any  purchase of shares upon  exercise of the Stock Option shall be subject
to compliance  with  applicable  law,  including the Bank Holding Company Act of
1956, as amended (the "BHC Act").  Notwithstanding  the termination of the Stock
Option,  Grantee shall be entitled to purchase the Option Shares with respect to
which it has  exercised  the Stock  Option in  accordance  with the terms hereof
prior to the  termination  of the Stock  Option.  The  termination  of the Stock
Option shall not affect any rights  hereunder which by their terms extend beyond
the date of such termination.

                  (b) As  used  herein,  a  "Purchase  Event"  means  any of the
following events:

                  (i) any  person  (other  than  Grantee  or any  subsidiary  of
         Grantee)  shall have  commenced  (as such term is defined in Rule 14d-2
         under the Exchange Act), or shall have filed a  registration  statement
         under the  Securities  Act with  respect to, a tender offer or exchange
         offer to purchase  any shares of Issuer  Common  Stock such that,  upon
         consummation  of such offer,  such person or a "group" (as such term is
         defined under the Exchange Act) of which such person is a member, would
         acquire beneficial  ownership (as such term is defined in Rule 13d-3 of
         the Exchange Act), or the right to acquire beneficial ownership, of 15%
         or more of the then outstanding  Issuer Common Stock (any such offer, a
         "Tender Offer"),  and the Board of Directors shall not have recommended
         against such tender offer or exchange  offer within 10 business days of
         such  commencement or filing or at any time thereafter  shall recommend
         acceptance thereof;

                  (ii) Issuer or any subsidiary of Issuer shall have authorized,
         recommended,  proposed or publicly announced an intention to authorize,
         recommend or propose,  or entered  into,  an agreement  with any person
         (other  than  Grantee or any  subsidiary  of  Grantee)  to (A) effect a
         merger, consolidation or other business combination involving Issuer or
         any of its  subsidiaries  (other than  internal  mergers,  reorganizing
         actions or  consolidations  involving  only  existing  subsidiaries  of
         Issuer),  (B) sell,  lease or otherwise  dispose of assets of Issuer or
         its subsidiaries  aggregating 15% or more of the  consolidated  assets,
         net revenues or net income of Issuer and its subsidiaries or (C) issue,
         sell  or   otherwise   dispose   of   (including   by  way  of  merger,
         consolidation,  share exchange or any similar  transaction)  securities
         representing  15% or more of the  voting  power of Issuer or any of its
         subsidiaries (any of the foregoing, an "Acquisition Transaction");

                   (iii) any person  (other than  Grantee or any  subsidiary  of
         Grantee)  shall have  acquired  beneficial  ownership  (as such term is
         defined in Rule 13d-3 under the  Exchange  Act) or the right to acquire
         beneficial  ownership of, or any "group" (as such term is defined under
         the Exchange Act) shall have been formed which beneficially owns or has
         the right to acquire  beneficial  ownership of, shares of Issuer Common
         Stock (other than trust account shares)  aggregating 15% or more of the
         then outstanding Issuer Common Stock;

                  (iv) (A) the  holders of Issuer  Common  Stock  shall not have
         approved the Merger Agreement at the meeting of such  shareholders held
         for the  purpose of voting on the Merger  Agreement,  (B) such  meeting
         shall  not  have  been  held or  shall  have  been  cancelled  prior to
         termination of the Merger  Agreement or (C) Issuer's Board of Directors
         shall have withdrawn

         or modified in a manner  adverse to Grantee or to Grantee's  ability to
         consummate the  transactions  contemplated by the Merger  Agreement the
         recommendation  of  Issuer's  Board of  Directors  with  respect to the
         Merger Agreement,  in each case after any person (other than Grantee or
         any subsidiary of Grantee) shall have (X) publicly announced,  or taken
         actions which have  resulted in public  disclosure  of, a proposal,  or
         publicly  disclosed an  intention  to make a proposal,  to engage in an
         Acquisition  Transaction  and shall not have withdrawn such proposal at
         least 10 business days prior to the  stockholders'  meeting to consider
         the Merger  (provided  that any public  disclosures  to the effect that
         such person intends to or may make another proposal shall result in the
         original proposal not being deemed to have been withdrawn) or (Y) filed
         an application (or given a notice),  whether in draft or final form, to
         the Federal Reserve Board, the OCC, the FDIC or any other  governmental
         or  regulatory  authority  for  approval  to engage  in an  Acquisition
         Transaction;  provided;  that the Stock Option shall not be exercisable
         upon the occurrence  specified in Section  2(b)(iv)(A) above unless and
         until any of the events  specified  in Section  2(b)(ii) or (iii) above
         shall have occurred; or

                  (v) (A) there  shall  exist a willful  or  intentional  breach
         under the Merger  Agreement  by Issuer and such  breach  would  entitle
         Grantee to  terminate  the Merger  Agreement;  and (B) within 12 months
         from the date of such  breach,  any of the events  specified in Section
         2(b)(ii) or (iii) above shall have occurred.

As used in this Agreement, "person" shall have the meaning specified in Sections
3(a)(9) and 13(d)(3) of the Exchange Act.

                  (c) In the event Grantee  wishes to exercise the Stock Option,
it shall send to Issuer a written  notice (an "Exercise  Notice" and the date of
which being  herein  referred to as a "Notice  Date")  specifying  (i) the total
number of Option  Shares that it intends to purchase  pursuant to such  exercise
and (ii) a place and date not earlier than three business days nor later than 20
business  days from the Notice Date for the closing of such purchase (a "Closing
Date");  provided  that if any closing of the purchase and sale  pursuant to the
Stock Option (a "Closing")  cannot be  consummated  by reason of any  applicable
order, injunction,  decree, judgment, law or regulation, the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which such  restriction  on  consummation  has expired or been  terminated;  and
provided further, without limiting the foregoing,  that if prior notification to
or  approval  of the  Federal  Reserve  Board,  the OCC,  the FDIC or any  other
governmental  or  regulatory  authority  is  required  in  connection  with such
purchase,  Grantee shall promptly file the required  notice or  application  for
approval and shall  expeditiously  process the same (and Issuer shall  cooperate
with Grantee in the filing of any such notice or  application  and the obtaining
of any such approval),  and the period of time that otherwise would run pursuant
to this sentence  shall run instead from the date on which,  as the case may be,
(A) any required  notification period has expired or been terminated or (B) such
approval has been obtained,  and in either event,  any requisite  waiting period
has passed.

                  (d)  Notwithstanding  Section  2(c),  in no  event  shall  any
Closing  Date occur later than 18 months after the related  Notice Date,  and if
such Closing shall not have occurred within 18 months after such Notice Date due
to the failure to obtain any required approval of the Federal Reserve Board, the
OCC, the FDIC or any other governmental or regulatory authority, the exercise of
the Stock Option or Substitute  Option  effected on such date shall be deemed to
have expired. In

                                        4

the event (i) Grantee receives  official notice that any such approval  required
for the  purchase  of Option  Shares  will not be issued  or  granted  or (ii) a
Closing Date shall not have occurred  within 18 months after the related  Notice
Date due to the failure to obtain any such  approval,  Grantee shall be entitled
to  exercise  its rights to exercise  the Stock  Option in  connection  with the
resale of Issuer  Common Stock or other  securities  pursuant to a  registration
statement as provided in Section 9. The provisions of this Section 2 and Section
4 shall apply with appropriate adjustments to any such exercise.

                  3.  Conditions to Closing.  The  obligation of Issuer to issue
Option  Shares to Grantee  hereunder is subject to the  conditions  that (a) all
consents, approvals, orders or authorizations of, or registrations, declarations
or filings  with,  the Federal  Reserve  Board,  the OCC,  the FDIC or any other
governmental or regulatory  authority,  if any,  required in connection with the
issuance of Option  Shares  hereunder  shall have been  obtained or made, as the
case may be,  and (b) no  order,  injunction  or  decree  issued by any court or
agency of  competent  jurisdiction  or other  legal  restraint  preventing  such
issuance shall be in effect.

                  4. Closing. At any Closing, (a) Issuer will deliver to Grantee

certificates  to be registered in the name of Grantee,  Merger Sub or such other
affiliate of Grantee as Grantee shall designate in the Exercise Notice and shall
bear the  legend  set forth in  Section  11,  representing  the number of Option
Shares  designated by Grantee in its Exercise Notice,  which Option Shares shall
be free and clear of all  Liens,  and (b)  Grantee  will  deliver  to Issuer the
aggregate Exercise Price for the Option Shares so designated and being purchased
at such  Closing  by wire  transfer  of  immediately  available  funds to a bank
account designated by Issuer.

                  5. Representations and Warranties of Issuer. Issuer represents
and warrants to Grantee that (a) Issuer is a corporation duly organized, validly
existing and in good  standing  under the laws of the State of Wisconsin and has
full  corporate  power and authority to execute and deliver this  Agreement and,
subject to any  approvals  referred to herein,  to consummate  the  transactions

necessary to permit  exercise in full of the Stock  Option,  all of which,  upon

                                        5

of  this   Agreement  by  Issuer  will  not  (1)  violate  the   certificate  of
incorporation  or by-laws of Issuer,  (2) conflict  with or violate any statute,
rule, regulation,  order, judgment or decree applicable to Issuer or by which it
or any of its assets or  properties  is bound or  affected  or (3) result in any

lapse of time or both would become a default)  under, or give rise to any rights
of termination,  amendment,  acceleration  or cancellation  of, or result in the
creation of any Lien on any of the property or assets of Issuer pursuant to, any
note, bond, mortgage,  indenture,  contract, agreement, lease, license, or other
instrument or obligation to which Issuer or any of its  subsidiaries  is a party
or by which  Issuer or any of its  assets  or  properties  is bound or  affected
(except,  in the case of clauses (2) and (3) above, for violations,  breaches or
defaults  which would not,  individually  or in the  aggregate,  have a Material
Adverse  Effect on Issuer)  and (g) any  provisions  of the  Wisconsin  Business
Corporation  Law or  Issuer's  Articles  of  Incorporation  prohibiting  certain
business  combinations  shall not  apply to  Grantee  in  respect  of  Grantee's
acquisition  of some or all of the Option  Shares and (h) Grantee  will not as a
result of its exercise of the Stock Option,  become subject to any anti-takeover
provisions, plans or arrangements in place at Issuer.

                  6.   Representations   and  Warranties  of  Grantee.   Grantee
represents  and  warrants  to Issuer  that (a)  Grantee  is a  corporation  duly

authorization,  execution and delivery by Issuer) this  Agreement  constitutes a
valid  and  binding  obligation  of  Grantee,  enforceable  against  Grantee  in

principles  of  equity  whether  applied  in a  court  of law or  equity  and by
bankruptcy, insolvency and similar laws affecting creditors' rights and remedies
generally, (d) the execution and delivery of this Agreement by Grantee does not,
and the  performance  of this  Agreement  by Grantee  will not (1)  violate  the

or lapse of time or both  would  become a  default)  under,  or give rise to any
rights of termination,  amendment, acceleration or cancellation of, or result in
the creation of a Lien on any of the property or assets of Grantee  pursuant to,
any note, bond, mortgage,  indenture,  contract,  agreement,  lease, license, or

Grantee) and (e) any Option  Shares  acquired  upon exercise of the Stock Option
will be, and the Stock Option is being,  acquired by Grantee for its own account
and not with a view to the public  distribution  or resale thereof in any manner

                  7.  Adjustment  upon  Changes  in  Capitalization;  Substitute
Option.  (a) In the event of any  change in Issuer  Common  Stock by reason of a
stock dividend, split-up,  recapitalization,  combination, exchange of shares or
similar transaction, the type and number of shares or securities


<PAGE>


                                        6

subject to the Stock Option, and the Exercise Price therefor,  shall be adjusted
appropriately,  and proper  provision shall be made in the agreements  governing
such  transaction,  so that Grantee  shall  receive  upon  exercise of the Stock
Option the  number  and class of shares or other  securities  or  property  that
Grantee  would have  received  in respect  of Issuer  Common  Stock if the Stock
Option had been  exercised  immediately  prior to such event or the record  date
therefor, as applicable.

                  (b) In the event that Issuer shall enter into an agreement (i)
to consolidate  with or merge into any person,  other than Grantee or one of its
subsidiaries,  and shall not be the continuing or surviving  corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one of
its  subsidiaries,  to merge into Issuer and Issuer shall be the  continuing  or
surviving corporation, but, in connection with such merger, the shares of Issuer
Common Stock  outstanding  immediately  prior to the consummation of such merger
shall be changed into or exchanged  for stock or other  securities  of Issuer or
any other person or cash or any other  property,  or the shares of Issuer Common
Stock  outstanding  immediately  prior to the  consummation of such merger shall
after such merger represent less than 50% of the outstanding  voting  securities
of  the  merged  company,  or  (iii)  to  sell  or  otherwise  transfer  all  or
substantially all of its assets to any person,  other than Grantee or one of its
subsidiaries,  then,  and in  each  such  case,  the  agreement  governing  such
transaction  shall make proper  provisions so that the Stock Option shall,  upon
the  consummation of any such  transaction and upon the terms and conditions set
forth herein,  be converted  into, or exchanged for, an option (the  "Substitute
Option"),  at the election of Grantee,  of either (A) the Acquiring  Corporation
(as defined  below) or (B) any person that  controls the  Acquiring  Corporation
(any such person being referred to as "Substitute Option Issuer").

                  (c) The  Substitute  Option  shall  have the same terms as the
Stock  Option;  provided that the exercise  price  therefor and number of shares
subject  thereto shall be as set forth in this Section 7; provided  further that
the Substitute Option shall be exercisable immediately upon issuance without the
occurrence of a Purchase  Event;  and provided  further that if the terms of the
Substitute  Option cannot,  for legal  reasons,  be the same as the Stock Option
(subject to the  variations  described in the  foregoing  provisos),  such terms
shall be as similar as possible  and in no event less  advantageous  to Grantee.
Substitute  Option  Issuer  shall also enter into an  agreement  with Grantee in
substantially  the  same  form  as this  Agreement  (subject  to the  variations
described  in  the  foregoing  provisos),  which  shall  be  applicable  to  the
Substitute Option.

                  (d) The Substitute Option shall be exercisable for such number
of shares of  Substitute  Common  Stock  (as  defined  below) as is equal to the
Assigned Value (as defined  below)  multiplied by the number of shares of Issuer
Common Stock for which the Stock Option was theretofore exercisable,  divided by
the Average Price (as defined below), rounded up to the nearest whole share. The
exercise  price per share of Substitute  Common Stock of the  Substitute  Option
(the  "Substitute  Option  Price")  shall  then be equal to the  Exercise  Price
multiplied  by a  fraction  in which the  numerator  is the  number of shares of
Issuer Common Stock for which the Stock Option was  theretofore  exercisable and
the denominator is the number of shares of Substitute Common Stock for which the
Substitute Option is exercisable.

                  (e) In no event,  pursuant to any of the foregoing paragraphs,
shall the Substitute  Option be exercisable for more than 19.9% of the aggregate
of the shares of Substitute  Common Stock  outstanding  prior to exercise of the
Substitute  Option. In the event that the Substitute Option would be exercisable
for more than 19.9% of the aggregate of the shares of outstanding Substitute

                                        7

Common Stock but for the  limitation in the first sentence of this Section 7(e),
Substitute  Option  Issuer  shall make a cash  payment  to Grantee  equal to the
excess of (i) the value of the  Substitute  Option  without giving effect to the
limitation in the first sentence of this Section 7(e) over (ii) the value of the
Substitute Option after giving effect to the limitation in the first sentence of
this Section 7(e).  This difference in value shall be determined by a nationally
recognized investment banking firm selected by Grantee.

                  (f) Issuer shall not enter into any  transaction  described in
Section 7(b) unless the Acquiring  Corporation  and any person that controls the
Acquiring  Corporation assume in writing all the obligations of Issuer hereunder
and take all other actions that may be necessary so that the  provisions of this
Section 7 are given full force and effect (including,  without  limitation,  any
action that may be  necessary  so that the holders of the other shares of common
stock issued by Substitute Option Issuer are not entitled to exercise any rights
by reason of the issuance or exercise of the Substitute Option and the shares of
Substitute  Common Stock are  otherwise in no way  distinguishable  from or have
lesser  economic  value than other shares of common  stock issued by  Substitute
Option Issuer (other than any  diminution in value  resulting from the fact that
the shares of Substitute Common Stock are restricted  securities,  as defined in
Rule 144 under the Securities Act or any successor provision)).

                  (g)  For  purposes  hereof,   the  following  terms  have  the
following meanings:

                  (1)  "Acquiring  Corporation"  means  (i)  the  continuing  or
         surviving  corporation  of a  consolidation  or merger  with Issuer (if
         other  than  Issuer),  (ii)  Issuer in a merger in which  Issuer is the
         continuing or surviving  corporation and (iii) the transferee of all or
         substantially all of Issuer's assets or deposits.

                  (2)  "Assigned  Value"  means the highest of (A) the price per
         share of  Issuer  Common  Stock at which a Tender  Offer  has been made
         after  the  date   hereof  and  prior  to  the   consummation   of  the
         consolidation,  merger or sale  referred  to in Section  7(b),  (B) the
         price per share to be paid by any third party or the  consideration per
         share to be received by holders of Issuer  Common  Stock,  in each case
         pursuant  to  the   agreement   with   Issuer   with   respect  to  the
         consolidation,  merger or sale  referred  to in Section  7(b),  (C) the
         highest closing sales price per share for Issuer Common Stock quoted on
         the National  Association of Securities  Dealers'  Automated  Quotation
         System (the "NASDAQS") or, if the shares of Issuer Common Stock are not
         quoted  thereon,  on the principal  trading market on which such shares
         are traded as  reported by a  recognized  source)  during the  12-month
         period immediately preceding the consolidation, merger or sale referred
         to in Section 7(b) and (D) in the event the transaction  referred to in
         Section 7(b) is a sale of all or  substantially  all of Issuer's assets
         and/or  deposits,  an amount  equal to (i) the sum of the price paid in
         such sale for such assets and/or  deposits and the current market value
         of the  remaining  assets of  Issuer,  as  determined  by a  nationally
         recognized investment banking firm selected by Grantee, divided by (ii)
         the number of shares of Issuer Common Stock  outstanding  at such time.
         In the event that a Tender Offer is made for Issuer  Common Stock or an
         agreement  is  entered  into for a merger  or  consolidation  involving
         consideration  other than cash,  the value of the  securities  or other
         property  issuable or  deliverable  in exchange for Issuer Common Stock
         shall be determined by a nationally  recognized investment banking firm
         selected by Grantee.

                                        8

                  (3) "Average  Price" means the average closing sales price per
         share of a share of Substitute  Common Stock quoted on the NASDAQS (or,
         if the shares of Substitute Common Stock are not quoted thereon, on the
         principal trading market on which such shares are traded as reported by
         a  recognized  source)  for  the one  year  immediately  preceding  the
         consolidation,  merger or sale in question, but in no event higher than
         the closing price of the shares of  Substitute  Common Stock on the day
         preceding  such  consolidation,   merger  or  sale;  provided  that  if
         Substitute Option Issuer is Issuer, the Average Price shall be computed
         with respect to a share of common  stock  issued by Issuer,  the person
         merging into Issuer or by any company which  controls  such person,  as
         Grantee may elect.

                  (4)  "Substitute  Common  Stock"  means the  shares of capital
         stock (or similar equity  interest)  with the greatest  voting power in
         respect of the election of directors (or persons similarly  responsible
         for the direction of the business and affairs) of the Substitute Option
         Issuer.

                  8. Cash-out  Rights.  If and to the extent the Stock Option is
not exercisable with respect to any of the Option Shares due to Article 9 of the
Articles of Incorporation of the Issuer,  Grantee has the right to, and may with
respect  to  such  Option  Shares  which  are  not  exercisable,   in  its  sole
determination,  elect to receive a cash  payment  in an amount  equal to (A) the
amount by which (1) the "Market/Tender  Offer Price" for shares of Issuer Common
Stock as of the date  Grantee  gives notice of its intent to exercise its rights
under this  Section 8 (defined as the higher of (x) the highest  price per share
of Issuer  Common Stock paid as of such date  pursuant to any tender or exchange
offer or other  Acquisition  Proposal  and (y) the average of the  closing  sale
prices of  shares  of  Issuer  Common  Stock on the  NASDAQS  or, if not  quoted
thereon,  the  principal  trading  market on which  such  shares are traded by a
recognized  source  for the 10 trading  days  immediately  preceding  such date)
exceeds (2) the Exercise Price, multiplied by the number of such Option Shares.

                  9.  Registration  Rights.  (a) Issuer  shall,  if requested by
Grantee  at any time and from time to time (a) within  three  years of the first
exercise  of  the  Stock  Option  or (b)  for 30  business  days  following  the
occurrence  of either of the events set forth in clauses (i) and (ii) of Section
2(d),  as  expeditiously  as possible  prepare  and file up to two  registration
statements  under the Securities Act if such  registration is necessary in order
to permit the sale or other  disposition of any or all shares of securities that
have been  acquired  by or are  issuable to Grantee  upon  exercise of the Stock
Option in  accordance  with the  intended  method  of sale or other  disposition
stated by Grantee,  including a "shelf'  registration  statement  under Rule 415
under the  Securities Act or any successor  provision,  and Issuer shall use its
best efforts to qualify  such shares or other  securities  under any  applicable
state securities  laws.  Grantee agrees to use its best efforts to cause, and to
cause any  underwriters of any sale or other  disposition to cause,  any sale or
other disposition  pursuant to such  registration  statement to be effected on a
widely  distributed  basis so that upon  consummation  thereof no  purchaser  or
transferee shall own beneficially more than 4.9% of the then outstanding  voting
power of  Issuer.  Issuer  shall use all  reasonable  efforts to cause each such
registration statement to become effective, to obtain all consents or waivers of
other  parties  which  are  required  therefor  and to  keep  such  registration
statement  effective for such period not in excess of 180 days from the day such
registration statement first becomes effective as may be reasonably necessary to
effect such sale or other disposition.  Any registration  statement prepared and
filed under this Section 9, and any sale covered  thereby,  shall be at Issuer's
expense except for underwriting discounts or commissions,  brokers' fees and the
fees and disbursements of Grantee's counsel related thereto.

                                        9


                  (b) In the  event  that  Grantee  requests  Issuer  to  file a
registration  statement  following the failure to obtain a required approval for
an exercise of the Stock Option as described in Section 2(d), the closing of the
sale or other disposition of Issuer Common Stock or other securities pursuant to
such registration  statement shall occur  substantially  simultaneously with the
exercise of the Stock Option.

                  (c) The  obligations  of Issuer under this Section 9 to file a
registration  statement and to maintain its  effectiveness  may be suspended for
one or more periods of time not  exceeding 60 days in the aggregate if the Board
of  Directors  of  Issuer  shall  have   determined  that  the  filing  of  such
registration  statement or the  maintenance of its  effectiveness  would require
premature  disclosure  of  nonpublic   information  that  would  materially  and
adversely affect Issuer.

                  (d) If  during  the  time  periods  referred  to in the  first
sentence of Section 9(a) Issuer effects a registration  under the Securities Act
of Issuer  Common  Stock for its own  account or for any other  stockholders  of
Issuer (other than on Form S-4 or Form S-8, or any successor form), Issuer shall
allow  Grantee  the  right  to  participate  in  such  registration,   and  such
participation   shall  not  affect  the  obligation  of  Issuer  to  effect  two
registration statements for Grantee under this Section 10; provided that, if the
managing  underwriters  of such offering  advise Issuer in writing that in their

of the other  party;  provided  that  Grantee  may assign all or any part of its
rights  hereunder  to (i) any  affiliate  thereof or (ii) any  person  after the
occurrence  of a  Purchase  Event.  Subject  to  the  preceding  sentence,  this
Agreement  will be binding upon,  inure to the benefit of and be  enforceable by
the  parties  and  their  respective  successors  and  assigns.  This  Agreement
(including the documents and instruments  referred to herein) is not intended to
confer  upon any person  other than the  parties  hereto any rights or  remedies
hereunder.

                  (b) Any Option Shares sold by a party in  compliance  with the

public  offering  pursuant to Section 9 shall not be required to bear the legend

this  Agreement  were not performed in accordance  with their  specific terms or
were  otherwise  breached.  It is  accordingly  agreed that the parties shall be
entitled to an injunction or injunctions  to prevent  breaches of this Agreement
and to enforce  specifically the terms and provisions hereof in any court of the

unenforceability  without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or  enforceability of
any of the terms or provisions of this Agreement in any other  jurisdiction.  If
any  provision  of  this  Agreement  is so  broad  as to be  unenforceable,  the
provision shall be interpreted to be only so broad as is enforceable.

                             STOCK OPTION AGREEMENT


                  STOCK  OPTION  AGREEMENT,  dated  as of May 14,  1997,  by and
between Associated Bank-Corp, a Wisconsin corporation (the "Issuer"),  and First
Financial Corporation, a Wisconsin corporation ("Grantee").

                  WHEREAS,  concurrently with the execution and delivery of this
Agreement,  Issuer,  Badger Merger Corp., a Wisconsin  corporation  and a wholly
owned  subsidiary  of Issuer  ("Merger  Sub"),  and Grantee are entering into an
Agreement  and  Plan  of  Merger,  dated  as of the  date  hereof  (the  "Merger
Agreement"),  which provides for, among other things, upon the terms and subject
to the conditions  thereof,  the merger of Merger Sub with and into Grantee (the
"Merger");

                  WHEREAS, as a condition to Grantee's willingness to enter into
the Merger Agreement,  Grantee has requested that the Issuer agree, and in order
to induce Grantee to enter into the Merger  Agreement,  Issuer has so agreed, to
grant to Grantee an option with  respect to certain  shares of  Issuer's  common
stock on the terms and subject to the conditions set forth herein; and

                  WHEREAS, as a condition to Issuer's  willingness to enter into
the Merger Agreement,  the Issuer has requested that Grantee agree, and in order
to induce the Issuer to enter into the Merger Agreement,  Grantee has so agreed,
to grant to Issuer an option with respect to certain shares of Grantee's  common
stock on substantially the same terms as set forth herein;

                  NOW,  THEREFORE,  in consideration of the foregoing and of the
mutual covenants,  representations,  warranties and agreements  contained herein
and in the Merger  Agreement;  and  intending to be legally  bound  hereby,  the
parties agree as follows:

                  1.  Grant  of  Option.   Issuer  hereby   grants   Grantee  an
irrevocable  option (the "Stock Option") to purchase up to (a) 4,465,361  shares
(the "Option Shares") of common stock, $0.01 par value per share, of Issuer (the
"Issuer Common Stock") or (b) if, immediately prior to exercise,  such number of
shares of Issuer  Common Stock is less than 19.9% of the issued and  outstanding
shares of Issuer Common Stock at the time of exercise of the Stock Option,  such
greater  number of shares of Issuer  Common  Stock as equals 19.9% of the issued
and  outstanding  shares of Issuer  Common Stock at such time of exercise of the
Stock Option, in the manner set forth below, at a price of $32.50 per share (the
"Exercise  Price"),  payable  in cash  in  accordance  with  Section  4  hereof.
Capitalized  terms used and not otherwise defined herein shall have the meanings
set forth in the Merger Agreement.

                  2.  Exercise  of  Option.  (a)  Subject to the  provisions  of
Sections 2(c) and (d), the Stock Option may be exercised by Grantee, in whole or
in part, at any time or from time to time following the occurrence of a Purchase
Event (as defined below), provided that, except as provided in the last sentence
of this Section  2(a),  the Stock Option  shall  terminate  and be of no further
force and effect upon the earliest to occur of (i) the Effective  Time,  (ii) 12
months after the first occurrence of


<PAGE>


                                        2

a Purchase  Event and (iii)  termination  of the Merger  Agreement in accordance
with its terms prior to the  occurrence of a Purchase  Event  (provided that the
Stock  Option  shall  not  terminate  for a period of 12  months  following  any
occurrence specified in Sections 2(b)(iv)(A) or 2(b)(v)(A); and provided further
that any  purchase of shares upon  exercise of the Stock Option shall be subject
to compliance  with  applicable  law,  including the Bank Holding Company Act of
1956, as amended (the "BHC Act").  Notwithstanding  the termination of the Stock
Option,  Grantee shall be entitled to purchase the Option Shares with respect to
which it has  exercised  the Stock  Option in  accordance  with the terms hereof
prior to the  termination  of the Stock  Option.  The  termination  of the Stock
Option shall not affect any rights  hereunder which by their terms extend beyond
the date of such termination.

                  (b) As  used  herein,  a  "Purchase  Event"  means  any of the
following events:

                  (i) any  person  (other  than  Grantee  or any  subsidiary  of
         Grantee)  shall have  commenced  (as such term is defined in Rule 14d-2
         under the Exchange Act), or shall have filed a  registration  statement
         under the  Securities  Act with  respect to, a tender offer or exchange
         offer to purchase  any shares of Issuer  Common  Stock such that,  upon
         consummation  of such offer,  such person or a "group" (as such term is
         defined under the Exchange Act) of which such person is a member, would
         acquire beneficial  ownership (as such term is defined in Rule 13d-3 of
         the Exchange Act), or the right to acquire beneficial ownership, of 15%
         or more of the then outstanding  Issuer Common Stock (any such offer, a
         "Tender Offer"),  and the Board of Directors shall not have recommended
         against such tender offer or exchange  offer within 10 business days of
         such  commencement or filing or at any time thereafter  shall recommend
         acceptance thereof;

                  (ii) Issuer or any subsidiary of Issuer shall have authorized,
         recommended,  proposed or publicly announced an intention to authorize,
         recommend or propose,  or entered  into,  an agreement  with any person
         (other  than  Grantee or any  subsidiary  of  Grantee)  to (A) effect a
         merger, consolidation or other business combination involving Issuer or
         any of its  subsidiaries  (other than  internal  mergers,  reorganizing
         actions or  consolidations  involving  only  existing  subsidiaries  of
         Issuer),  (B) sell,  lease or otherwise  dispose of assets of Issuer or
         its subsidiaries  aggregating 15% or more of the  consolidated  assets,
         net revenues or net income of Issuer and its subsidiaries or (C) issue,
         sell  or   otherwise   dispose   of   (including   by  way  of  merger,
         consolidation,  share exchange or any similar  transaction)  securities
         representing  15% or more of the  voting  power of Issuer or any of its
         subsidiaries (any of the foregoing, an "Acquisition Transaction");

                   (iii) any person  (other than  Grantee or any  subsidiary  of
         Grantee)  shall have  acquired  beneficial  ownership  (as such term is
         defined in Rule 13d-3 under the  Exchange  Act) or the right to acquire
         beneficial  ownership of, or any "group" (as such term is defined under
         the Exchange Act) shall have been formed which beneficially owns or has
         the right to acquire  beneficial  ownership of, shares of Issuer Common
         Stock (other than trust account shares)  aggregating 15% or more of the
         then outstanding Issuer Common Stock;

                  (iv) (A) the  holders of Issuer  Common  Stock  shall not have
         approved  the  increase  in the number of  authorized  shares of Issuer
         Common Stock or the issuance of Issuer Common Stock in connection  with
         the Merger at the meeting of such  shareholders held for the purpose of
         voting on the  increase  in the number of  authorized  shares of Issuer
         Common

         Stock and the issuance of Issuer  Common Stock in  connection  with the
         Merger,  (B) such  meeting  shall not have been held or shall have been
         cancelled prior to termination of the Merger  Agreement or (C) Issuer's
         Board of Directors shall have withdrawn or modified in a manner adverse
         to  Grantee or to  Grantee's  ability to  consummate  the  transactions
         contemplated  by the Merger  Agreement the  recommendation  of Issuer's
         Board of Directors with respect to the Merger  Agreement,  in each case
         after any person  (other  than  Grantee or any  subsidiary  of Grantee)
         shall have (X) publicly announced, or taken actions which have resulted
         in public disclosure of, a proposal, or publicly disclosed an intention
         to make a proposal,  to engage in an Acquisition  Transaction and shall
         not have withdrawn such proposal at least 10 business days prior to the
         stockholders'  meeting  to  consider  the  increase  in the  number  of
         authorized  shares of Issuer  Common  Stock or the  issuance  of Issuer
         Common Stock in connection  with the Merger  (provided  that any public
         disclosures  to the  effect  that such  person  intends  to or may make
         another proposal shall result in the original proposal not being deemed
         to have  been  withdrawn)  or (Y)  filed  an  application  (or  given a
         notice),  whether in draft or final form, to the Federal Reserve Board,
         the OCC, the FDIC or any other governmental or regulatory authority for
         approval to engage in an  Acquisition  Transaction;  provided  that the
         Stock Option shall not be exercisable upon the occurrence  specified in
         Section  2(b)(iv)(A) above unless and until any of the events specified
         in Section 2 (b)(ii) or (iii) above shall have occurred; or

                  (v) (A) there  shall  exist a willful  or  intentional  breach
         under the Merger  Agreement  by Issuer and such  breach  would  entitle
         Grantee to  terminate  the Merger  Agreement;  and (B) within 12 months
         from the date of such  breach,  any of the events  specified in Section
         2(b)(ii) or (iii) above shall have occurred.

As used in this Agreement, "person" shall have the meaning specified in Sections
3(a)(9) and 13(d)(3) of the Exchange Act.

                  (c) In the event Grantee  wishes to exercise the Stock Option,
it shall send to Issuer a written  notice (an "Exercise  Notice" and the date of
which being  herein  referred to as a "Notice  Date")  specifying  (i) the total
number of Option  Shares that it intends to purchase  pursuant to such  exercise
and (ii) a place and date not earlier than three business days nor later than 20
business  days from the Notice Date for the closing of such purchase (a "Closing
Date");  provided  that if any closing of the purchase and sale  pursuant to the
Stock Option (a "Closing")  cannot be  consummated  by reason of any  applicable
order, injunction,  decree, judgment, law or regulation, the period of time that
otherwise would run pursuant to this sentence shall run instead from the date on
which such  restriction  on  consummation  has expired or been  terminated;  and
provided further, without limiting the foregoing,  that if prior notification to
or  approval  of the  Federal  Reserve  Board,  the OCC,  the FDIC or any  other
governmental  or  regulatory  authority  is  required  in  connection  with such
purchase,  Grantee shall promptly file the required  notice or  application  for
approval and shall  expeditiously  process the same (and Issuer shall  cooperate
with Grantee in the filing of any such notice or  application  and the obtaining
of any such approval),  and the period of time that otherwise would run pursuant
to this sentence  shall run instead from the date on which,  as the case may be,
(A) any required  notification period has expired or been terminated or (B) such
approval has been obtained,  and in either event,  any requisite  waiting period
has passed.

                                        4

                  (d)  Notwithstanding  Section  2(c),  in no  event  shall  any
Closing  Date occur later than 18 months after the related  Notice Date,  and if
such Closing shall not have occurred within 18 months after such Notice Date due
to the failure to obtain any required approval of the Federal Reserve Board, the
OCC, the FDIC or any other governmental or regulatory authority, the exercise of
the Stock Option or Substitute  Option  effected on such date shall be deemed to
have expired.  In the event (i) Grantee  receives  official notice that any such
approval  required  for the  purchase  of  Option  Shares  will not be issued or
granted or (ii) a Closing  Date shall not have  occurred  within 18 months after
the related Notice Date due to the failure to obtain any such approval,  Grantee
shall be  entitled  to  exercise  its  rights to  exercise  the Stock  Option in
connection with the resale of Issuer Common Stock or other  securities  pursuant
to a  registration  statement as provided in Section 8. The  provisions  of this
Section 2 and Section 4 shall  apply with  appropriate  adjustments  to any such
exercise.

                  3.  Conditions to Closing.  The  obligation of Issuer to issue
Option  Shares to Grantee  hereunder is subject to the  conditions  that (a) all
consents, approvals, orders or authorizations of, or registrations, declarations
or filings  with,  the Federal  Reserve  Board,  the OCC,  the FDIC or any other
governmental or regulatory  authority,  if any,  required in connection with the
issuance of Option  Shares  hereunder  shall have been  obtained or made, as the
case may be,  and (b) no  order,  injunction  or  decree  issued by any court or
agency of  competent  jurisdiction  or other  legal  restraint  preventing  such
issuance shall be in effect.

                  4. Closing. At any Closing, (a) Issuer will deliver to Grantee
a  certificate  or  certificates  in  definitive   form,  such   certificate  or
certificates to be registered in the name of Grantee, or such other affiliate of
Grantee as Grantee  shall  designate in the  Exercise  Notice and shall bear the
legend  set forth in  Section  11,  representing  the  number  of Option  Shares

similar laws affecting creditors' rights and remedies generally,  (d) Issuer has
taken all necessary  corporate  action to authorize and reserve for issuance and
to permit it to issue, upon exercise of the Stock Option,  and at all times from

by which it or any of its  assets  or  properties  is bound or  affected  or (3)

to any rights of termination,  amendment,  acceleration  or cancellation  of, or
result in the  creation  of any Lien on any of the  property or assets of Issuer
pursuant to, any note, bond, mortgage,  indenture,  contract,  agreement, lease,
license,  or  other  instrument  or  obligation  to which  Issuer  or any of its
subsidiaries is a party or by which Issuer or any of its assets or properties is
bound  or  affected  (except,  in the case of  clauses  (2) and (3)  above,  for
violations,  breaches  or  defaults  which  would  not,  individually  or in the
aggregate,  have a Material  Adverse Effect on Issuer) and (g) any provisions of

                  6.   Representations   and  Warranties  of  Grantee.   Grantee
represents  and  warrants  to Issuer  that (a)  Grantee  is a  corporation  duly

transactions  contemplated  hereunder,  (b) the  execution  and delivery of this
Agreement and the consummation of the transactions contemplated hereby have been

Agreement  has been duly  executed and  delivered by Grantee and  (assuming  due
authorization,  execution and delivery by Issuer) this  Agreement  constitutes a
valid  and  binding  obligation  of  Grantee,  enforceable  against  Grantee  in

bankruptcy, insolvency and similar laws affecting creditors' rights and remedies

                  7.  Adjustment  upon  Changes  in  Capitalization;  Substitute
Option.  (a) In the event of any  change in Issuer  Common  Stock by reason of a
stock dividend, split-up,  recapitalization,  combination, exchange of shares or
similar transaction,  the type and number of shares or securities subject to the
Stock Option, and the Exercise Price therefor,  shall be adjusted appropriately,
and proper provision shall be made in the agreements governing such transaction,
so that Grantee  shall  receive upon exercise of the Stock Option the number and
class of shares or other securities or property that Grantee would have received
in  respect  of Issuer  Common  Stock if the  Stock  Option  had been  exercised
immediately prior to such event or the record date therefor, as applicable.

                  (b) In the event that Issuer shall enter into an agreement (i)
to consolidate  with or merge into any person,  other than Grantee or one of its
subsidiaries,  and shall not be the continuing or surviving  corporation of such
consolidation or merger, (ii) to permit any person, other than Grantee or one of
its  subsidiaries,  to merge into Issuer and Issuer shall be the  continuing  or
surviving corporation, but, in connection with such merger, the shares of Issuer
Common Stock  outstanding  immediately  prior to the consummation of such merger
shall be changed into or exchanged  for stock or other  securities  of Issuer or
any other person or cash or any other  property,  or the shares of Issuer Common
Stock  outstanding  immediately  prior to the  consummation of such merger shall
after such merger represent less than 50% of the outstanding  voting  securities
of  the  merged  company,  or  (iii)  to  sell  or  otherwise  transfer  all  or
substantially all of its assets to any person,  other than Grantee or one of its
subsidiaries,  then,  and in  each  such  case,  the  agreement  governing  such
transaction  shall make proper  provisions so that the Stock Option shall,  upon
the  consummation of any such  transaction and upon the terms and conditions set
forth herein,  be converted  into, or exchanged for, an option (the  "Substitute
Option"),  at the election of Grantee,  of either (A) the Acquiring  Corporation
(as defined  below) or (B) any person that  controls the  Acquiring  Corporation
(any such person being referred to as "Substitute Option Issuer").

                  (c) The  Substitute  Option  shall  have the same terms as the
Stock  Option;  provided that the exercise  price  therefor and number of shares
subject  thereto shall be as set forth in this Section 7; provided  further that
the Substitute Option shall be exercisable immediately upon issuance without the
occurrence of a Purchase  Event;  and provided  further that if the terms of the
Substitute  Option cannot,  for legal  reasons,  be the same as the Stock Option
(subject to the  variations  described in the  foregoing  provisos),  such terms
shall be as similar as possible  and in no event less  advantageous  to Grantee.
Substitute  Option  Issuer  shall also enter into an  agreement  with Grantee in
substantially  the  same  form  as this  Agreement  (subject  to the  variations
described  in  the  foregoing  provisos),  which  shall  be  applicable  to  the
Substitute Option.

                  (d) The Substitute Option shall be exercisable for such number
of shares of  Substitute  Common  Stock  (as  defined  below) as is equal to the
Assigned Value (as defined  below)  multiplied by the number of shares of Issuer
Common Stock for which the Stock Option was theretofore exercisable,  divided by
the Average Price (as defined below), rounded up to the nearest whole share. The
exercise  price per share of Substitute  Common Stock of the  Substitute  Option
(the  "Substitute  Option  Price")  shall  then be equal to the  Exercise  Price
multiplied  by a  fraction  in which the  numerator  is the  number of shares of
Issuer Common Stock for which the Stock Option was  theretofore  exercisable and
the denominator is the number of shares of Substitute Common Stock for which the
Substitute Option is exercisable.

                                        7

                  (e) In no event,  pursuant to any of the foregoing paragraphs,
shall the Substitute  Option be exercisable for more than 19.9% of the aggregate
of the shares of Substitute  Common Stock  outstanding  prior to exercise of the
Substitute  Option. In the event that the Substitute Option would be exercisable
for more than 19.9% of the  aggregate  of the shares of  outstanding  Substitute
Common Stock but for the  limitation in the first sentence of this Section 7(e),
Substitute  Option  Issuer  shall make a cash  payment  to Grantee  equal to the
excess of (i) the value of the  Substitute  Option  without giving effect to the
limitation in the first sentence of this Section 7(e) over (ii) the value of the
Substitute Option after giving effect to the limitation in the first sentence of
this Section 7(e).  This difference in value shall be determined by a nationally
recognized investment banking firm selected by Grantee.

                  (f) Issuer shall not enter into any  transaction  described in
Section 7(b) unless the Acquiring  Corporation  and any person that controls the
Acquiring  Corporation assume in writing all the obligations of Issuer hereunder
and take all other actions that may be necessary so that the  provisions of this
Section 7 are given full force and effect (including,  without  limitation,  any
action that may be  necessary  so that the holders of the other shares of common
stock issued by Substitute Option Issuer are not entitled to exercise any rights
by reason of the issuance or exercise of the Substitute Option and the shares of
Substitute  Common Stock are  otherwise in no way  distinguishable  from or have
lesser  economic  value than other shares of common  stock issued by  Substitute
Option Issuer (other than any  diminution in value  resulting from the fact that
the shares of Substitute Common Stock are restricted  securities,  as defined in
Rule 144 under the Securities Act or any successor provision)).

                  (g)  For  purposes  hereof,   the  following  terms  have  the
following meanings:

                  (1)  "Acquiring  Corporation"  means  (i)  the  continuing  or
         surviving  corporation  of a  consolidation  or merger  with Issuer (if
         other  than  Issuer),  (ii)  Issuer in a merger in which  Issuer is the
         continuing or surviving  corporation and (iii) the transferee of all or
         substantially all of Issuer's assets or deposits.

                  (2)  "Assigned  Value"  means the highest of (A) the price per
         share of  Issuer  Common  Stock at which a Tender  Offer  has been made
         after  the  date   hereof  and  prior  to  the   consummation   of  the
         consolidation,  merger or sale  referred  to in Section  7(b),  (B) the
         price per share to be paid by any third party or the  consideration per
         share to be received by holders of Issuer  Common  Stock,  in each case
         pursuant  to  the   agreement   with   Issuer   with   respect  to  the
         consolidation,  merger or sale  referred  to in Section  7(b),  (C) the
         highest closing sales price per share for Issuer Common Stock quoted on
         the National  Association of Securities  Dealers'  Automated  Quotation
         System (the  "NASDAQS")  (or, if the shares of Issuer  Common Stock are
         not  quoted  thereon,  on the  principal  trading  market on which such
         shares  are  traded as  reported  by a  recognized  source)  during the
         12-month period immediately preceding the consolidation, merger or sale
         referred  to in  Section  7(b)  and (D) in the  event  the  transaction
         referred to in Section  7(b) is a sale of all or  substantially  all of
         Issuer's assets and/or deposits,  an amount equal to (i) the sum of the
         price paid in such sale for such assets and/or deposits and the current
         market value of the  remaining  assets of Issuer,  as  determined  by a
         nationally  recognized  investment  banking  firm  selected by Grantee,
         divided by (ii) the number of shares of Issuer Common Stock outstanding
         at such  time.  In the  event  that a Tender  Offer is made for  Issuer
         Common Stock or an agreement is entered into for a merger


<PAGE>


                                        8

         or consolidation  involving consideration other than cash, the value of
         the  securities or other  property  issuable or deliverable in exchange
         for Issuer Common Stock shall be determined by a nationally  recognized
         investment banking firm selected by Grantee.

                  (3) "Average  Price" means the average closing sales price per
         share of a share of Substitute  Common Stock quoted on the NASDAQS (or,
         if the shares of Substitute Common Stock are not quoted thereon, on the
         principal trading market on which such shares are traded as reported by
         a  recognized  source)  for  the one  year  immediately  preceding  the
         consolidation,  merger or sale in question, but in no event higher than
         the closing price of the shares of  Substitute  Common Stock on the day
         preceding  such  consolidation,   merger  or  sale;  provided  that  if
         Substitute Option Issuer is Issuer, the Average Price shall be computed
         with respect to a share of common  stock  issued by Issuer,  the person
         merging into Issuer or by any company which  controls  such person,  as
         Grantee may elect.

                  (4)  "Substitute  Common  Stock"  means the  shares of capital
         stock (or similar equity  interest)  with the greatest  voting power in
         respect of the election of directors (or persons similarly  responsible
         for the direction of the business and affairs) of the Substitute Option
         Issuer.

                  8.  Registration  Rights.  (a) Issuer  shall,  if requested by
Grantee  at any time and from time to time (a) within  three  years of the first
exercise  of  the  Stock  Option  or (b)  for 30  business  days  following  the
occurrence  of either of the events set forth in clauses (i) and (ii) of Section
2(d),  as  expeditiously  as possible  prepare  and file up to two  registration
statements  under the Securities Act if such  registration is necessary in order
to permit the sale or other  disposition of any or all shares of securities that
have been  acquired  by or are  issuable to Grantee  upon  exercise of the Stock
Option in  accordance  with the  intended  method  of sale or other  disposition
stated by Grantee,  including a "shelf'  registration  statement  under Rule 415
under the  Securities Act or any successor  provision,  and Issuer shall use its
best efforts to qualify  such shares or other  securities  under any  applicable
state securities  laws.  Grantee agrees to use its best efforts to cause, and to
cause any  underwriters of any sale or other  disposition to cause,  any sale or
other disposition  pursuant to such  registration  statement to be effected on a
widely  distributed  basis so that upon  consummation  thereof no  purchaser  or
transferee shall own beneficially more than 4.9% of the then outstanding  voting
power of  Issuer.  Issuer  shall use all  reasonable  efforts to cause each such
registration statement to become effective, to obtain all consents or waivers of
other  parties  which  are  required  therefor  and to  keep  such  registration
statement  effective for such period not in excess of 180 days from the day such
registration statement first becomes effective as may be reasonably necessary to
effect such sale or other disposition.  Any registration  statement prepared and
filed under this Section 9, and any sale covered  thereby,  shall be at Issuer's
expense except for underwriting discounts or commissions,  brokers' fees and the
fees and disbursements of Grantee's counsel related thereto.

                  (b) In the  event  that  Grantee  requests  Issuer  to  file a
registration  statement  following the failure to obtain a required approval for
an exercise of the Stock Option as described in Section 2(d), the closing of the
sale or other disposition of Issuer Common Stock or other securities pursuant to
such registration  statement shall occur  substantially  simultaneously with the
exercise of the Stock Option.

                                        9

                  (c) The  obligations  of Issuer under this Section 8 to file a
registration  statement and to maintain its  effectiveness  may be suspended for
one or more periods of time not  exceeding 60 days in the aggregate if the Board
of  Directors  of  Issuer  shall  have   determined  that  the  filing  of  such
registration  statement or the  maintenance of its  effectiveness  would require
premature  disclosure  of  nonpublic   information  that  would  materially  and
adversely affect Issuer.

                  (d) If  during  the  time  periods  referred  to in the  first
sentence of Section 8(a) Issuer effects a registration  under the Securities Act
of Issuer  Common  Stock for its own  account or for any other  stockholders  of
Issuer (other than on Form S-4 or Form S-8, or any successor form), Issuer shall
allow  Grantee  the  right  to  participate  in  such  registration,   and  such
participation   shall  not  affect  the  obligation  of  Issuer  to  effect  two
registration statements for Grantee under this Section 8 ; provided that, if the
managing  underwriters  of such offering  advise Issuer in writing that in their
opinion the number of shares of Issuer Common Stock  requested to be included in
such registration exceeds the number which can be sold in such offering,  Issuer
shall  include the shares  requested to be included  therein by Grantee pro rata
with the shares intended to be included therein by Issuer.

                  (e) Grantee shall provide all information reasonably requested
by Issuer for inclusion in any registration statement to be filed hereunder.  In
connection with any registration  pursuant to this Section 8, Issuer and Grantee
shall  provide each other and any  underwriter  of the offering  with  customary
representations,  warranties,  covenants,  indemnification  and  contribution in
connection with such registration.

                  9. Restrictive Legends.  Each certificate  representing Option
Shares issued to Grantee  hereunder shall initially be endorsed with a legend in
substantially the following form:

                  THE SECURITIES  REPRESENTED BY THIS  CERTIFICATE HAVE NOT BEEN
         REGISTERED  UNDER THE  SECURITIES  ACT OF 1933, AS AMENDED,  AND MAY BE
         REOFFERED OR SOLD ONLY IF SO  REGISTERED  OR IF AN EXEMPTION  FROM SUCH
         REGISTRATION AND APPLICABLE  STATE  SECURITIES LAWS IS AVAILABLE.  SUCH
         SECURITIES ARE ALSO SUBJECT TO ADDITIONAL  RESTRICTIONS  ON TRANSFER AS
         SET FORTH IN THE STOCK OPTION AGREEMENT,  DATED MAY 14, 1997, A COPY OF
         WHICH MAY BE OBTAINED FROM THE ISSUER HEREOF.

                  10.  NASDAQS  Listing.  Upon any exercise of the Stock Option,
Issuer shall use its best efforts to cause the shares of Issuer  Common Stock to
be acquired in connection  with such exercise of the Stock Option to be approved
for  listing on the  NASDAQS  and each other  securities  exchange on which such
shares are listed as soon as practicable after such exercise.

                  11. Assignment;  Third Party  Beneficiaries.  (a) Neither this
Agreement nor any of the rights, interests or obligations of any party hereunder
shall be assigned by any of the parties  hereto  (whether by operation of law or
otherwise)  without  prior  written  consent of the other party;  provided  that
Grantee may assign all or any part of its rights  hereunder to (i) any affiliate
thereof or (ii) any person after the occurrence of a Purchase Event.  Subject to
the  preceding  sentence,  this  Agreement  will be binding  upon,  inure to the
benefit of and be enforceable by the parties and their respective successors and
assigns. This Agreement (including the documents and instruments referred


<PAGE>


                                       10

to herein) is not  intended  to confer  upon any person  other than the  parties
hereto any rights or remedies hereunder.

                  (b) Any Option Shares sold by a party in  compliance  with the
provisions of Section 9 shall,  upon  consummation  of such sale, be free of the
restrictions imposed with respect to such shares by this Agreement.  In no event
will any  transferee  of any Option  Shares be entitled to the rights of Grantee
hereunder.

                  (c)  Certificates  representing  shares  sold in a  registered
public  offering  pursuant to Section 8 shall not be required to bear the legend
set forth in Section 9.

                  12.  Enforcement  of the  Agreement.  The parties hereto agree
that  irreparable  damage would occur in the event that any of the provisions of
this  Agreement  were not performed in accordance  with their  specific terms or
were  otherwise  breached.  It is  accordingly  agreed that the parties shall be
entitled to an injunction or injunctions  to prevent  breaches of this Agreement
and to enforce  specifically the terms and provisions hereof in any court of the
United  States or any state having  jurisdiction,  this being in addition to any
other remedy to which they are entitled at law or in equity.

                  13. Entire Agreement.  This Agreement and the Merger Agreement
(together  with the other  documents and  instruments  referred to in the Merger
Agreement)  constitute the entire  agreement and supersede all prior  agreements
and understandings, both written and oral, among the parties with respect to the
subject matter hereof.

                  14.  Further  Assurances.  Each party will execute and deliver
all such further  documents and  instruments and take all such further action as
may be necessary in order to consummate the transactions contemplated hereby.

                  15.  Severability.  Any term or  provision  of this  Agreement
which  is  invalid  or  unenforceable  in any  jurisdiction  shall,  as to  that
jurisdiction,   be   ineffective   to  the   extent   of  such   invalidity   or
unenforceability  without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or  enforceability of
any of the terms or provisions of this Agreement in any other  jurisdiction.  If
any  provision  of  this  Agreement  is so  broad  as to be  unenforceable,  the
provision shall be interpreted to be only so broad as is enforceable.

                  16. Notices.  All notices and other  communications  hereunder
shall be in writing and shall be deemed given if delivered personally, mailed by
registered or certified mail (return receipt  requested) or delivered by express
courier (with  confirmation) to the parties at the following  addresses (or such
other address for a party as shall be specified by like notice):

              ASSOCIATED BANC-CORP AND FIRST FINANCIAL CORPORATION
                                 AGREE TO MERGE

GREEN BAY,  WISC.  and  STEVENS  POINT,  WISC.,  May 14,  1997 - - H.B.  Conlon,
chairman and chief executive officer for Associated Banc-Corp (NASDAQ/NMS),  and
John C.  Seramur,  president  and chief  executive  officer for First  Financial
Corporation, today announced the signing of a definitive agreement to merge in a
stock-for-stock transaction. This merger of equals will result in an institution
with combined  assets of $10.5  billion,  equity capital of  approximately  $900
million,  and a network of over 220 full-service  banking  locations  throughout
Wisconsin and Illinois.

         The  merger  agreement,  which  has  been  approved  by the  boards  of
directors  of both  institutions,  provides  for each  share of First  Financial
Corporation common stock to be exchanged for .765 shares of Associated Banc-Corp
common stock on a tax-free basis. Based on Tuesday's (5/13/97) closing price for
Associated  Banc-Corp common stock,  the market value of the combined  companies
would be approximately $2 billion.

         The merger,  which requires  approval by shareholders of both companies
and regulatory authorities, is expected to be completed late in 1997. The merger
will be accounted for as a pooling-of-interests.

         The  merged  company  will  retain  the  Associated   Banc-Corp   name.
Headquarters  has been designated to be in Green Bay, and it is anticipated that
significant  operations  will  remain  in both  Stevens  Point  and  Green  Bay.
Associated  Banc-Corp Chief  Executive  Officer H.B. Conlon will be Chairman and
CEO of the combined companies.  John C. Seramur,  First Financial  Corporation's
chief executive  officer,  will be named Vice Chairman and will remain president
of First  Financial  during the  integration  period.  Robert C.  Gallagher will
remain as Vice  Chairman of  Associated.  The board of directors of the combined
institution  will consist of seven of the existing  directors from each company.
Pursuant to the execution of the definitive  agreement to merge,  both companies
executed a stock option  agreement  providing  for the purchase of 19.9% of each
other's common stock under specified circumstances.

         Conlon,  chairman and chief executive officer of Associated  Banc-Corp,
said, "This  transaction  joins two institutions  which have had a distinguished
track record  serving  their  respective  markets and  creating  value for their
shareholders.  The  resources  and  expertise  of these  two  premier  financial
institutions are highly  complementary.  This merger will further serve the best
interests of the customers and shareholders of the combined  institution.  It is
based on an enhanced ability to provide a wide range of high

quality financial  services to consumers and businesses in the communities which
our banks serve.  The merger will  considerably  expand our collective reach and
market share,  and is  consistent  with the  long-term  strategic  plans of both
companies. We are enthusiastic about the prospects for this transaction."

         "Both of our  companies  have  been  successful  in  terms  of  overall
performance  and  return to  shareholders.  Our future  prospects  as a combined
company  far exceed  what we could  accomplish  on an  individual  basis,"  said
Seramur, president and chief executive officer of First Financial. "Early in our
conversations,  we realized  that both of our  companies  focus on the  customer
through the provision of superior  customer  service by  outstanding  employees.
This will be the foundation of our future success as a combined company."

         The proposed  transaction is expected to be earnings  accretive  during
fiscal year 1998,  the first full year of  consolidation.  The combined  company
anticipates taking a material one-time charge and one-time confirming accounting
adjustment  of at  least  $40,000,000,  net of  taxes,  in  connection  with the
transaction,  the  exact  amount  of which  has not yet been  determined.  It is
further anticipated that transactional  economies will result in pre-tax savings
totaling  approximately  $10 million in the first full year of consolidation and
is expected to increase in future years.

         The complementary  financial products and services offered by these two
institutions  are  expected  to  contribute  to the  future  performance  of the
combined  institution.  The financial  statements of the combined companies will
have capital  levels  materially in excess of regulatory  minimums.  Pursuant to
this announcement,  First Financial Corporation indicated that it is immediately
terminating its previously announced stock buyback program.

         The branch  systems of the two companies  have only minimal  geographic
overlap.  Therefore,  the  combined  company  will have a much  stronger  branch
franchise throughout  Wisconsin and Illinois.  For example, the company will now
be the third  largest  bank in Wisconsin in terms of deposit  market  share.  In
addition,  it will be the only bank in Illinois to have office representation in
the  state's  four top  banking  markets - Chicago,  Peoria,  Rockford,  and the
Illinois portion of the St. Louis metropolitan area.

         "The  compatibility of our two companies is just tremendous in terms of
the broad array of banking services that we can bring to our community markets,"
emphasized Conlon.  "Associated will add trust and asset management services and
business  banking to the product mix  currently  offered at the First  Financial
offices. First Financial brings a strong and profitable credit card operation to
the  combined  company,  along  with a sizable  and  growing  home  equity  loan
portfolio. In addition, both of our companies are strong mortgage originators."

                  "Our shared focus on the customer will be greatly  enhanced as
a result of this merger," noted Seramur.  "Both  Associated and First  Financial
are  focusing  on  technology  to  improve   customer   service.   The  combined
organization  will have greater  critical  mass to invest in ways to improve our
delivery of products and financial services."

                  "We  realize  that  mergers  can  be  disruptive  and  we  are
committed  to making this a smooth  transition,"  stated  Seramur.  "Both of our
companies  have  been  involved  in  numerous  acquisitions,  and  we  have  the
experience to make this a positive transition for our customers and employees."

                  "Our customers will have access to over 220 branch offices and
150 ATMs," added Conlon.  "Existing and new business  customers will be provided
with a wider variety of products and services,  supported by decision  making at
the local level."

         Both companies are very active  participants  in their local  community
markets,  and this  commitment  will be continued by the  combined  bank.  Every
effort  will  be  made  to  promote   community   development  and  reinvestment
opportunities in these markets.

         Associated-Banc-Corp is headquartered in Green Bay, WI. The diversified
multi-bank  holding company  currently has $4.4 billion in assets with more than
2,000  employees  and  over 98  banking  locations  in  Wisconsin  and  northern
Illinois.  Associated  offers a variety  of  financially  related  products  and
services to complement its traditional line of banking products.

         First  Financial  Corporation  is  one of the  largest  thrift  holding
companies  in the country  and  provides a broad  range of  financial  products,
including commercial and residential  mortgages,  appraisals,  consumer and home
equity loans,  insurance,  and credit cards.  First Financial has assets of $5.8
