ITEM 5.  OTHER EVENTS.

                    MERGER AGREEMENT WITH MUTUAL SAVINGS BANK

         On February 22, 2000, First Northern Capital Corp., a Wisconsin
corporation ("First Northern"), and Mutual Savings Bank, a Wisconsin-chartered
mutual savings bank ("Mutual"), issued a joint press release announcing that
they had entered into an Agreement and Plan of Merger, dated as of February 21,
2000 (the "Merger Agreement"), by and among Mutual, First Northern and OV Corp.,
a Wisconsin corporation organized as a wholly owned subsidiary of Mutual for the
purpose of effecting the transactions contemplated by the Merger Agreement
("Merger Corp."). The Merger Agreement provides for the acquisition of First
Northern by Mutual through a merger of First Northern with and into Merger Corp.
(the "Merger"), which will be the surviving corporation ("Survivor"). (Survivor
is referred to in the press release as "Mid-Tier HC".) The Merger Agreement has
been approved by the boards of directors of Mutual and First Northern.

         Subject to the terms and conditions of the Merger Agreement, at the
time of the Merger, each outstanding share of First Northern common stock, par
value $1.00 per share ("First Northern Common Stock"), will be converted into
the right to receive cash in the amount of $15.00, or 1.5 shares of common
stock, par value $.01 per share, of Survivor ("Survivor Common Stock"), or a
combination of cash and shares of Survivor Common Stock (the "Merger
Consideration"). Prior to the closing date, Mutual will select the percentage of
the total Merger Consideration to be paid in Survivor Common Stock, which may
not be less than 40% or more than 70%; the balance will be paid in cash. Each
First Northern shareholder will be entitled to elect to receive (a) cash, (b)
Survivor Common Stock or (c) as to First Northern shareholders holding not less
than 170 shares of First Northern Common Stock, a combination of cash and
Survivor Common Stock, with the percentage of such shares of their First
Northern Common Stock equal to the lesser of the Stock Percentage and 50%
converted into Survivor Common Stock and the balance converted into cash.
Elections will be subject to proration if the cash or stock elections exceed the
maximum amounts permitted under the Merger Agreement. Cash will be paid in lieu
of any fractional shares of Survivor Common Stock which holders of First
Northern Common Stock would otherwise receive.

         In connection with the Merger, Mutual and First Northern will engage in
a restructuring involving a number of steps (the "Restructuring"). As part of
the Restructuring, Mutual will form a mutual holding company in which Mutual's
depositors will hold all the voting rights. The mutual holding company will own
a majority of the Survivor Common Stock; the balance of the shares of Survivor
Common Stock will be offered for sale to Mutual's depositors and issued to First
Northern shareholders in the Merger. As a result of the Restructuring, Mutual
Savings Bank and First Northern Savings Bank, S.A., will become wholly owned
subsidiaries of Survivor. Thus, Survivor will be a subsidiary mid-tier stock
holding company.

         Consummation of the Merger is subject to the satisfaction of certain
closing conditions set forth in the Merger Agreement, including approval by the
shareholders of First Northern and approval by the Office of Thrift Supervision,
the Federal Deposit Insurance Corporation and the Administrator of the Division
of Savings Institutions of the Wisconsin Department of Financial Institutions.
The depositors of Mutual must also approve Mutual's plan for the Restructuring.
The Merger is also subject to receipt of an opinion of counsel to the effect
that the Merger will constitute a reorganization within the meaning of Section
368(a) of the Internal Revenue Code and the receipt of an opinion of counsel or
a private letter ruling from the Internal Revenue Service as to the federal
income tax treatment of certain transactions contemplated by the Merger
Agreement. In addition, the Merger is conditioned upon the approval for listing
on the NASDAQ National Market of the shares of Survivor Common Stock to be
issued in the Merger, which shares will be registered under the Securities Act
of 1933 by a registration statement to be filed by Survivor with the Securities
and Exchange Commission.

         Concurrently with the execution of the Merger Agreement, in order to
induce Mutual to enter into the Merger Agreement, the parties entered into a
Stock Option Agreement by which First Northern granted to Mutual


                                       -2-

an irrevocable option to purchase up to 1,708,675 shares of First Northern
Common Stock, which equals 19.9% of the number of shares of First Northern
Common Stock outstanding on February 21, 2000, at an exercise price of $9.0375
per share. The option would become exercisable under certain circumstances if
First Northern becomes the subject of a third-party proposal for a competing
transaction.

         The Merger Agreement, the Stock Option Agreement and the joint press
release announcing the Merger Agreement are filed as exhibits to this report.
The brief descriptions of the Merger Agreement and the Stock Option Agreement in
this report are qualified by reference to the full text of those documents.

                    (iv)  "Maximum Cash Number" shall mean that number equal to:

                          (A) (1) the Cash Percentage; multiplied by (2) the
number of shares of First Northern Common Stock issued and outstanding
immediately prior to the Effective Time; minus

                          (B) the number of shares of First Northern Common
Stock to be exchanged for Fraction Payments.

                    (v)   "Maximum Stock Number" shall mean that number equal
to: (A) the Stock Percentage; multiplied by (B) the number of shares of First
Northern Common Stock issued and outstanding immediately prior to the Effective
Time.

                    (vi)  "Merger Consideration" shall mean the shares of
Survivor Common Stock issuable pursuant to this Section 2.8 of this Agreement
and cash payable pursuant to this Section 2.8 of this Agreement.

                    (vii) "Stock Percentage" shall mean that percentage selected
by Mutual in the Conversion Notice which shall be (at the option of Mutual) any
percentage between and including 40% and 70%.

              (b)   Conversion Notice. At least three business days prior to the
Closing Date, Mutual shall send a notice to First Northern (the "Conversion
Notice") which specifies Mutual's election as to the amounts of the Cash
Percentage and the Stock Percentage. The parties shall then proceed to close the
transactions described in this Agreement on the basis of such election
identified in the Conversion Notice.

              (c)   Conversion. At the Effective Time, by virtue of the Merger
and without any action on the part of Merger Corp., First Northern, Mutual or
the holders of First Northern Common Stock, each share of First Northern Common
Stock issued and outstanding at the Effective Time (except for treasury stock
which shall be canceled as described in Section 2.8(m) of this Agreement) shall
be converted into and become the right to receive:



                                      -15-

<PAGE>   23



                    (i)   cash in the amount of the Cash Value; or

                    (ii)  that number of shares of Survivor Common Stock equal
to the Exchange Ratio; or

                    (iii) a combination of cash and shares of Survivor Common
Stock determined in accordance with the provisions of this Section 2.8 of this
Agreement.

              (d)   Maximum Numbers. The number of shares of First Northern
Common Stock to be converted into the right to receive Survivor Common Stock in
the Merger shall equal the Maximum Stock Number. The number of shares of First
Northern Common Stock to be converted into the right to receive cash in the
Merger shall equal the Maximum Cash Number. Notwithstanding any other provisions
of this Agreement, at least 40% of the number of shares of First Northern Common
Stock issued and outstanding immediately prior to the Effective Time shall be
converted into whole shares of Survivor Common Stock.

              (e)   Elections. Subject to the allocation and election procedures
set forth in this Section 2.8 of this Agreement, each record holder immediately
prior to the Effective Time of shares of First Northern Common Stock will be
entitled in respect to all of the shares of First Northern Common Stock owned by
such holder: (i) to elect to receive cash for such shares (a "Cash Election");
(ii) to elect to receive Survivor Common Stock for such shares (a "Stock
Election"); (iii) to indicate that such record holder has no preference as to
the receipt of cash or Survivor Common Stock for such shares (a "Non-Election");
or (iv) as to First Northern Shareholders holding not less than 170 shares of
First Northern Common Stock, to elect to receive a combination of cash and
Survivor Common Stock, with the percentage of such shares of First Northern
Common Stock equal to the lesser of (x) the Stock Percentage and (y) 50%
converted into Survivor Common Stock and the balance converted into cash (a
"Mixed Election"). All such elections shall be made on a form designed by
Mutual, which is reasonably satisfactory to First Northern, for that purpose (a
"Form of Election"). Holders of record of shares of First Northern Common Stock
who hold such shares as nominees, trustees or in other representative capacities
(a "Representative") may submit multiple Forms of Election, provided that such
Representative certifies that each such Form of Election covers all the shares
of First Northern Common Stock held by each Representative for a particular
beneficial owner. Shareholders who are not Representatives must make a single
election for all shares of First Northern Common Stock held by them.

              (f)   Cash Elections in Excess of Maximum Cash Number. If the
aggregate number of shares covered by Cash Elections (the "Cash Election
Shares") together with the portion of shares to be converted into cash pursuant
to Mixed Elections exceeds the Maximum Cash Number:

                    (i)   each share of First Northern Common Stock covered by a
Stock Election (the "Stock Election Shares") and each share of First Northern
Common Stock covered by a Non-Election (the "Non-Election Shares") shall be
converted into the right to receive a


                                      -16-

<PAGE>   24



number of shares of Survivor Common Stock equal to the Exchange Ratio, and each
share of First Northern Common Stock covered by a Mixed Election (the "Mixed
Election Shares") shall be converted as provided in the Mixed Election; and

                    (ii)  each Cash Election Share shall be converted into the
right to receive:

                          (A) an amount in cash, without interest, equal to: (1)
the Cash Value; multiplied by (2) a fraction (the "Cash Fraction"), the
numerator of which shall be the difference between (I) the Maximum Cash Number
and (II) the product of the number of Mixed Election Shares times the Cash
Percentage and the denominator of which shall be the total number of Cash
Election Shares; and

                          (B) a number of shares of Survivor Common Stock equal
to: (1) the Exchange Ratio; multiplied by (2) a fraction equal to one minus the
Cash Fraction.

                          (C) Notwithstanding the foregoing provisions, to avoid
the ongoing expense of very small shareholder accounts, prior to the Effective
Time, Mutual and First Northern may agree that, notwithstanding the foregoing
proration, the shares of First Northern Common Stock of any First Northern
Shareholder who has made a Cash Election and who as a result of the foregoing
proration would otherwise receive fewer than 25 (or such smaller number as may
be agreed upon by Mutual and First Northern) shares of Survivor Common Stock
shall have their First Northern Common Stock converted solely into cash. In that
event, the proportions of cash and Survivor Common Stock to be received by other
First Northern Shareholders who have made a Cash Election shall be appropriately
adjusted to reflect a pro rata allocation of remaining available cash and
Survivor Common Stock among such other First Northern Shareholders.

              (g)   Stock Elections in Excess of Maximum Stock Number. If the
aggregate number of Stock Election Shares, together with the portion of shares
to be converted into shares of Survivor Common Stock pursuant to Mixed Elections
exceeds the Maximum Stock Number:

                    (i)   each Cash Election Share and each Non-Election Share
shall be converted into the right to receive cash in the amount of the Cash
Value, and each Mixed Election Share shall be converted as provided in the Mixed
Election; and

                    (ii)  each Stock Election Share shall be converted into the
right to receive:

                          (A) a number of shares of Survivor Common Stock equal
to: (1) the Exchange Ratio; multiplied by (2) a fraction (the "Stock Fraction"),
the numerator of which shall be the difference between (I) the Maximum Stock
Number and (II) the product of the number of Mixed Election Shares times the
Stock Percentage and the denominator of which shall be the total number of Stock
Election Shares, and


                                      -17-

<PAGE>   25



                          (B) an amount in cash, without interest, equal to: (1)
the Cash Value; multiplied by (2) a fraction equal to one minus the Stock
Fraction.

              (h)   Other. In the event that neither Section 2.8(f) or 2.8(g) of
this Agreement is applicable: (i) each Cash Election Share shall be converted
into the right to receive cash in the amount of the Cash Value; (ii) each Stock
Election Share shall be converted into the right to receive a number of shares
of Survivor Common Stock equal to the Exchange Ratio; and (iii) each
Non-Election Share shall be converted into the right to receive shares of
Survivor Common Stock and the right to receive cash on a proportionate basis so
that the total number of shares of First Northern Common Stock converted into
the right to receive shares of Survivor Common Stock and cash, respectively,
approximate the Maximum Stock Number and the Maximum Cash Number, respectively,
as closely as possible.

              (i)   Initial Mailing. Mutual and First Northern will mail a Form
of Election to all holders of record of shares of First Northern Common Stock as
of a date mutually agreed to by First Northern and Mutual (the "Initial Mailing
Record Date") which shall be approximately 45 calendar days prior to the
anticipated Effective Time. Elections shall be made by holders of First Northern
Common Stock by mailing to the Exchange Agent a Form of Election. To be
effective, a Form of Election must be properly completed, signed and submitted
to the Exchange Agent and accompanied by the certificates representing the
shares of First Northern Common Stock ("First Northern Certificates") as to
which the election is being made (or by an appropriate guarantee of delivery of
such certificates as set forth in such Form of Election from a member of any
registered national securities exchange or of the National Association of
Securities Dealers, Inc. or a commercial bank or trust company having an office
or correspondent in the United States, provided such certificates are in fact
delivered by the time set forth in such guarantee of delivery). Mutual will have
the discretion, which it may delegate in whole or in part to the Exchange Agent,
to determine whether Forms of Election have been properly completed, signed and
submitted or revoked and to disregard immaterial defects in Forms of Election.
The decision of Mutual (or the Exchange Agent) in such matters shall be
conclusive and binding. Neither Mutual nor the Exchange Agent will be under any
obligation to notify any Person of any defect in a Form of Election submitted to
the Exchange Agent. The Exchange Agent shall also make all computations
contemplated by this Section 2.8 of this Agreement and all such computations
shall be conclusive and binding on the holders of First Northern Common Stock
absent manifest error in any such computation.

              (j)   Nonsubmittal. For the purposes hereof, a holder of First
Northern Common Stock who does not submit a Form of Election which is received
by the Exchange Agent prior to the Election Deadline shall be deemed to have
made a Non-Election. If Mutual or the Exchange Agent shall determine that any
purported Cash Election or Stock Election was not properly made, such purported
Cash Election or Stock Election shall be deemed to be of no force and effect and
the Person making such purported Cash Election or Stock Election shall, for all
purposes hereof, be deemed to have made a Non-Election.

<PAGE>   26



              (k)   Subsequent Mailings. Mutual and First Northern shall each
use its reasonable best efforts to promptly mail the Form of Election to all
Persons who become holders of First Northern Common Stock during the period
between the Initial Mailing Record Date and 10:00 a.m. New York time, on the
date ten calendar days prior to the anticipated Effective Time and to make the
Form of Election available to all Persons who become holders of First Northern
Common Stock subsequent to such day and no later than the close of business on
the third business day prior to the Effective Time.

              (l)   Election Deadline. A Form of Election must be received by
the Exchange Agent by the close of business on the third business day prior to
the Effective Time (the "Election Deadline") in order to be effective. All
elections will be irrevocable.

              (m)   Treasury Stock. Any shares of First Northern Common Stock
that are owned by First Northern or any First Northern Subsidiary, except in a
fiduciary capacity, at the Effective Time shall be canceled and retired and
cease to exist and no cash or shares of Survivor Common Stock shall be issued or
delivered in exchange therefor.

              (n)   Adjustment. In the event that, prior to the Effective Time,
there is a reclassification, stock split or stock dividend with respect to
outstanding Survivor Common Stock or outstanding First Northern Common Stock, an
appropriate and proportionate adjustment, if any, shall be made to any or one or
more of the Cash Value or the Exchange Ratio.

       2.9    Exchange of First Northern Certificates.

              (a)   Exchange Agent. As of the Effective Time, Survivor shall
deposit, or shall cause to be deposited, with a bank or trust company designated
by Survivor and reasonably acceptable to First Northern (the "Exchange Agent"),
for the benefit of the holders of shares of First Northern Common Stock, for
exchange in accordance with this Article II of this Agreement through the
Exchange Agent: (i) certificates representing the aggregate number of shares of
Survivor Common Stock issuable pursuant to Section 2.8 of this Agreement; and
(ii) cash representing the aggregate amount of cash payable pursuant to Section
2.8 of this Agreement; (such certificates for shares of Survivor Common Stock,
together with any dividends or distributions with respect thereto, such cash and
any Fraction Payment, being hereinafter referred to as the "Exchange Fund").

              (b)   Exchange Procedures.

                    (i) At or promptly after the Effective Time, Survivor shall
cause the Exchange Agent to mail to each holder of record of a First Northern
Certificate which immediately prior to the Effective Time of Merger represented
outstanding shares of First Northern Common Stock and which was not submitted to
the Exchange Agent with a duly executed and completed Form of Election: (A) a
letter of transmittal ("Letter of Transmittal") which shall specify that
delivery shall be effected, and risk of loss and title to the First Northern
Certificates shall pass, only upon delivery of the First Northern Certificates
to the Exchange


                                      -19-

<PAGE>   27



Agent and which shall be in such form and have such other customary provisions
as Survivor may reasonably specify and which are reasonably acceptable to First
Northern; and (B) instructions to effect the surrender of the First Northern
Certificates in exchange for cash or shares of Survivor Common Stock, or both,
as described in this Agreement.

                    (ii)  Upon surrender of a First Northern Certificate for
cancellation to the Exchange Agent together with either a Form of Election or a
Letter of Transmittal, in each case duly executed, and with such other documents
as the Exchange Agent may reasonably require, the holder of such First Northern
Certificate shall be entitled to receive, and Survivor shall cause the Exchange
Agent to promptly deliver in exchange therefor after the Effective Time: (A) a
certificate representing that number of whole shares of Survivor Common Stock to
which such holder is entitled to receive in respect of such First Northern
Certificate pursuant to Section 2.8 of this Agreement; and (B) a check
representing the cash that such holder is entitled to receive in respect of such
First Northern Certificate pursuant to Section 2.8 of this Agreement; and (C) a
check for any Fraction Payment. The First Northern Certificate so surrendered
shall forthwith be canceled; provided, however, that fractional share interests
of any one holder shall be aggregated to maximize the number of whole shares of
Survivor Common Stock to be issued and minimize the Fraction Payments.

                    (iii) In the event of a transfer of ownership of shares of
First Northern Common Stock which is not registered in the transfer records of
First Northern, a certificate representing the proper number of shares of
Survivor Common Stock, a check for the proper amount of cash that such holder is
entitled to receive in respect of such First Northern Certificate pursuant to
Section 2.8 of this Agreement and any Fraction Payment, shall be delivered to
the transferee if the First Northern Certificate which represented such shares
of First Northern Common Stock 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.

                    (iv)  No interest will be paid or accrued on the cash and
shares of Survivor Common Stock to be issued pursuant to this Agreement, the
cash in lieu of fractional shares, if any, and unpaid dividends and
distributions on the shares of Survivor Common Stock, if any, payable to First
Northern Shareholders.

                    (v)   If any First Northern Certificate shall have been
lost, stolen or destroyed, upon the making of an affidavit of that fact by the
Person claiming such First Northern Certificate to be lost, stolen or destroyed
and, if required by Survivor in its reasonable discretion, the posting by such
Person of a bond in such reasonable amount as Survivor may direct as indemnity
against any claim that may be made against it with respect to such First
Northern Certificate, the Exchange Agent will deliver in exchange for such lost,
stolen or destroyed First Northern Certificate, a certificate representing the
proper number of shares of Survivor Common Stock and a check for the cash, in
each case that such First Northern Shareholder has the right to receive pursuant
to Section 2.8 of this Agreement, and the Fraction Payment, if any, with respect
to the shares of First Northern Common Stock formerly represented


                                      -20-

<PAGE>   28



thereby, and unpaid dividends and distributions on the shares of Survivor Common
Stock, if any, as provided in this Article II of this Agreement.

                    (vi)  Until surrendered as contemplated by this Section 2.9
of this Agreement, each First Northern Certificate shall be deemed at all times
after the Effective Time to represent only the right to receive upon surrender
only the cash or shares of Survivor Common Stock, or both, and any Fraction
Payment.

              (c)   Distributions with Respect to Unexchanged Shares. If any
Survivor Common Stock is issued pursuant to the Merger, no dividends or other
distributions declared or made after the Effective Time with respect to Survivor
Common Stock with a record date after the Effective Time shall be paid to the
holder of any unsurrendered First Northern Certificate with respect to the
shares of Survivor Common Stock represented thereby, and no Fraction Payment
shall be paid to any such holder, until the holder of such First Northern
Certificate has surrendered such First Northern Certificate to the Exchange
Agent. Subject to the effect of any applicable Law, following the surrender of
any such First Northern Certificate, there shall be paid to the holder of the
surrendered First Northern Certificate, without interest: (i) promptly, any
Fraction Payment to which such holder is entitled and the amount of dividends or
other distributions with a record date after the Effective Time of Merger
theretofore paid with respect to such whole shares of Survivor 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 Survivor Common Stock.

              (d)   No Further Rights in First Northern Common Stock. All shares
of Survivor Common Stock issued and cash paid upon conversion of the First
Northern Common Stock in accordance with the terms of this Agreement shall be
deemed to have been issued and paid in full satisfaction of all rights
pertaining to the First Northern Common Stock.

              (e)   No Fractional Shares. No fractional shares of Survivor
Common Stock shall be issued in the Merger. All fractional share interests of a
holder of more than one First Northern Certificate at the Effective Time shall
be aggregated. If a fractional share interest results after such aggregation,
each holder of a fractional interest shall be paid an amount in cash equal to
the product obtained by multiplying such fractional interest by the Cash Value.
Promptly after the determination of the amount of cash to be paid to holders of
fractional interests, the Exchange Agent shall notify Survivor and Survivor
shall deliver such amounts to such holders subject to and in accordance with the
terms of Section 2.9(c) of this Agreement.

              (f)   Investment of Exchange Fund. The Exchange Agent shall invest
any cash included in the Exchange Fund as directed by Survivor. Any interest and
other income resulting from such investments shall be paid to Survivor. In the
event the cash in the Exchange Fund shall be insufficient to fully satisfy all
of the payment obligations to be made by the Exchange Agent hereunder, then
Survivor shall promptly deposit cash into the Exchange Fund in an


                                      -21-

<PAGE>   29



amount which is equal to the deficiency in the amount of cash required to fully
satisfy such payment obligations.

              (g)   Termination of Exchange Fund. Any portion of the Exchange
Fund which remains undistributed to the First Northern Shareholders after twelve
(12) months after the Effective Time shall be delivered to Survivor, upon
demand, and any First Northern Shareholders who have not theretofore complied
with this Article II of this Agreement shall thereafter look only to Survivor
for payment of their claim for cash or shares of Survivor Common Stock, or both,
any cash in lieu of fractional share interests and any dividends or
distributions with respect thereto.

              (h)   No Liability. Neither the Exchange Agent nor any party to
this Agreement shall be liable to any First Northern Shareholder for any shares
of First Northern Common Stock or Survivor Common Stock (or dividends or
distributions with respect thereto) or cash delivered in accordance with
applicable Law to a public official pursuant to any abandoned property, escheat
or similar Law.

              (i)   Withholding Rights. Survivor shall be entitled to deduct and
withhold from the consideration otherwise payable pursuant to this Agreement to
any First Northern Shareholder such amounts as Survivor 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 Survivor, such withheld amounts shall be treated for all purposes of
this Agreement as having been paid to the First Northern Shareholder in respect
of which such deduction and withholding was made by Survivor.

              (j)   Uncertificated Shares. Notwithstanding any other provision
of this Agreement, the Form of Election and the Letter of Transmittal may, at
the option of Survivor, provide for the ability of a holder of one or more First
Northern Certificates to elect that Survivor Common Stock to be received in
exchange for the First Northern Common Stock formerly represented by such
surrendered First Northern Certificates be issued in uncertificated form.

              (k)   Stock Transfer Books. At the Effective Time, the stock
transfer books of First Northern shall be closed and there shall be no further
registration of transfers of shares of First Northern Common Stock thereafter on
the records of First Northern. From and after the Effective Time, the holders of
First Northern Certificates outstanding immediately prior to the Effective Time
shall cease to have any rights with respect to such shares of First Northern
Common Stock except as otherwise provided in this Agreement or by Law.

       2.10   Reorganization. The parties intend that this Agreement be a plan
of reorganization within the meaning of Section 368(a) of the Code and that the
Merger be a tax-free reorganization under Section 368(a) of the Code to the
extent that shares of First Northern Common Stock are exchanged for shares of
Survivor Common Stock as described in this Agreement. No party shall voluntarily
take or cause to be taken any action which would disqualify the Merger as a
tax-free reorganization under Section 368 of the Code.


                                      -22-

<PAGE>   30




       2.11   No Dissenting Shares. The parties acknowledge that under the WBCL,
the First Northern Shareholders are not entitled to dissent from the Merger and
are not entitled to require appraisal of their First Northern Common Stock.

       2.12   Meeting of First Northern Shareholders.

              (a)   First Northern will promptly take all steps necessary to
cause the First Northern Meeting to be duly called, noticed, and held as soon as
practicable for the purpose of voting to approve this Agreement, the Stock
Option Agreement (if required), the Merger and all matters related thereto.
First Northern will use its best efforts to secure the required approval of its
Shareholders.

              (b)   Merger Corp. and First Northern will prepare and file with
the SEC the Registration Statement and the Proxy Statement, respectively, as
soon as reasonably practicable after the date of this Agreement. Merger Corp.,
Mutual and First Northern shall use reasonable best efforts to cause the Proxy
Statement to be cleared for mailing, and the Registration Statement to be
declared effective under the Securities Act as promptly as practicable after
such filing. First Northern will cause to be mailed to its Shareholders a notice
of the Meeting and the Proxy Statement as soon as practicable thereafter. Merger
Corp., Mutual and First Northern shall also take such action as may be
reasonably required to cause any shares of Survivor Common Stock issuable
pursuant to the Merger to be registered or to obtain an exemption from
registration or qualification under applicable state "blue sky" or securities
Laws; provided, however, that Merger Corp. shall not be required to qualify as a
foreign corporation or to file any general consent to service of process under
the Laws of any jurisdiction. Each party to this Agreement will furnish to the
other parties all information concerning itself as each such other party or its
counsel may reasonably request and which is required or customary for inclusion
in the Proxy Statement and the Registration Statement.

              (c)   The Proxy Statement shall include the recommendation of the
Board of Directors of First Northern in favor of the Merger; provided, however,
that if the Board of Directors of First Northern shall, in good faith and after
receiving the written opinion of its legal counsel, determine that to make such
a recommendation would be a violation of its fiduciary obligations under
applicable Law, then the Board of Directors of First Northern shall not be
obligated to make any such recommendation.

       2.13   Liquidation Account and Sub-Accounts. The liquidation account and
sub-account balances of the Bank shall be continued for the benefit of certain
account holders of the Bank who maintain their accounts in the Bank in the event
of a complete liquidation of the Bank. The liquidation account balance shall be
subject to downward adjustment to the extent of any downward adjustment to any
sub-account balance in accordance with Section 563b.3(f) of the regulations of
the OTS. A distribution of each sub-account balance may be made only in the
event of a complete liquidation of the Bank and only out of funds available for
such purpose after payment of all creditors but before any payments to
stockholders.


                                      -23-

       2.14   Restructuring. In connection with the Merger, Mutual and First
Northern will conduct a series of transactions, as set forth below (the
"Restructuring"):

              (a)   Mutual will convert from a state-chartered savings bank to a
federal savings bank.

              (b)   Bank will convert from a state-chartered savings and loan
association to a federal savings bank.

              (c)   Mutual will form a mutual holding company ("MHC"). MHC will
also form a transitory federal stock savings bank ("Transitory"). Mutual will
contribute the shares of Merger Corp. to MHC. MHC would thereupon own all of the
stock of both Merger Corp. and Transitory.

              (d)   Mutual will convert to a federal stock savings bank ("Stock
Bank"). Mutual's depositors would receive deposit accounts in Stock Bank with
the same terms and conditions as their deposit accounts in Mutual.

              (e)   Transitory would merge into Stock Bank in a transaction in
which MHC would receive all of the stock of Stock Bank.

              (f)   MHC would transfer the stock of Stock Bank to Merger Corp.
so that Merger Corp. would hold all of the stock of Stock Bank, and MHC would
initially own 100% of the shares of common stock of Merger Corp. The former
depositors of Mutual would hold all of the liquidation and voting interest in
MHC, for so long as, and to the extent, they continue to maintain their deposits
with Stock Bank.

              (g)   Simultaneously with the Merger, Survivor would issue shares
of its stock to the public and the Survivor Employee Benefit Plans for cash, at
the price to purchasers of $10.00 per share.

              (h)   As a result of the Merger, Survivor will be the sole
stockholder of Bank.

       Therefore, as a result of the Restructuring and the Merger, Bank and
Stock Bank would become "sister" corporations owned by Survivor. MHC would own
at least 51% of the stock of Survivor, and the new public shareholders, the
former shareholders of First Northern and Survivor Employee Benefit Plans would
together own 49% or less of the stock of Survivor.

       The amount of Survivor Common Stock to be offered to the public would be
determined so that the total of Survivor Common Stock issued to First Northern
Shareholders, new investors and reserved for options or the other compensation
programs for directors and employees of Survivor and its Subsidiaries would
constitute less than 50% of the total Survivor Common Stock, and the balance
would be owned by MHC.

       The Restructuring is subject to certain regulatory approvals. After the
Restructuring is effected, Mutual agrees that it will assume and timely
discharge any and all obligations, covenants and agreements of First Northern
under this Agreement which are to be performed or discharged after the Effective
Time, but which have not been fully performed or discharged as of the time the
Restructuring is effected. Mutual agrees, however, that it will not alter the
structure of the Restructuring as described herein if it would: (i) alter,
change or reduce the amount of the consideration to be paid to holders of First
Northern Common Stock or the manner or basis upon which such exchange is made;
(ii) have an adverse federal or state income tax consequence to First Northern,
or any of the shareholders of First Northern; (iii) have an adverse effect on
the shareholders of First Northern Common Stock; or (iv) would be likely to
delay or jeopardize receipt of the Regulatory Approvals or satisfaction of any
of the conditions to the Merger set forth in Article VII.

       2.15   Anti-Dilution Provisions. In the event that between the date of
this Agreement and the Effective Time the issued and outstanding shares of First
Northern Common Stock shall have been changed into a different number of shares
as a result of a stock split, reverse stock split, stock dividend,
recapitalization, reclassification or other similar transaction, or in the event
the number of authorized and unissued shares of First Northern Common Stock
subject to issuance upon the exercise of outstanding First Northern Stock
Options shall have changed between the date of this Agreement and the Effective
Time as the result of the granting of additional First Northern Stock Options,
then the per share merger consideration shall be adjusted appropriately, so long
as the aggregate consideration remains the same.

       2.16   Alternative Structure. Notwithstanding anything in this Agreement
to the contrary, Mutual may specify (subject to First Northern's approval, which
shall not be unreasonably withheld) that any of its or MHC's direct or indirect
subsidiaries, and First Northern and any of its direct or indirect subsidiaries
shall enter into transactions other than those described in this Article II, in
order to effect the purposes of this Agreement, and Mutual and First Northern
shall take all action necessary and appropriate to effect, or cause to be
affected, such transactions; provided, however, that (i) other than a change in
structure required by a regulatory agency having jurisdiction over the
transactions contemplated by this Agreement, no such specification shall
materially and adversely affect the timing of the consummation of the
transactions contemplated herein; or (ii) no such specifications shall
materially and adversely affect the tax effect or economic benefits of the
Merger to the holders of First Northern Common Stock or to Mutual's members or
the fundamental structure of the mid-tier holding company in the Restructuring.
Such alternative structure may include substitution of a federally chartered
holding company for Merger Corp., if required by relevant regulators.


                                   ARTICLE III
                                OTHER AGREEMENTS

       3.1 Confidentiality; Access. The Confidentiality Agreement shall remain
in full force and effect, except that numbered paragraph 4 thereof ("Other
Discussions") shall be superceded


                                      -25-

<PAGE>   33



by this Agreement and of no further force and effect. Upon reasonable notice,
each of First Northern and Mutual shall afford to the other's officers,
employees, accountants, legal counsel and other representatives access, during
normal business hours, to all of its and its Subsidiaries' properties, books,
contracts, commitments and records; provided that First Northern and Mutual
shall have the right to redact any information from such materials which relates
to assessments, analyses or discussions of a possible Acquisition engaged in by
it prior to the date of this Agreement, or which, relates to matters or issues
concerning its evaluation of the Merger or its obligations under this Agreement,
or that would impair its Board of Directors' ability to discharge its fiduciary
duties.

       3.2    Disclosure Schedules.

              (a)   Contemporaneously with the execution and delivery of this
Agreement, First Northern is delivering to Mutual the First Northern Disclosure
Schedule, which is accompanied by a certificate signed by the Chief Executive
Officer and Secretary of First Northern stating that the First Northern
Disclosure Schedule is being delivered pursuant to this Agreement and is the
First Northern Disclosure Schedule referred to in this Agreement. The First
Northern Disclosure Schedule is deemed to constitute an integral part of this
Agreement and to modify the representations, warranties, covenants or agreements
of First Northern contained in this Agreement to the extent that such
representations, warranties, covenants or agreements expressly refer to the
First Northern Disclosure Schedule.

              (b)   Contemporaneously with the execution and delivery of this
Agreement, Mutual is delivering to First Northern the Mutual Disclosure
Schedule, which is accompanied by a certificate signed by the Chief Executive
Officer and Secretary of Mutual stating that the Mutual Disclosure Schedule is
being delivered pursuant to this Agreement and is the Mutual Disclosure Schedule
referred to in this Agreement. The Mutual Disclosure Schedule is deemed to
constitute an integral part of this Agreement and to modify the representations,
warranties, covenants or agreements of Mutual contained in this Agreement to the
extent that such representations, warranties, covenants or agreements expressly
refer to the Mutual Disclosure Schedule.

              (c)   All capitalized terms used in the Disclosure Schedules shall
have the definitions specified in this Agreement. All descriptions or listings
of documents contained in the Disclosure Schedules are qualified in their
entirety by reference to the documents so described, true copies of which
heretofore have been delivered or made available to the other. Except as
expressly stated to the contrary in the Disclosure Schedules, disclosure of a
matter or document in a Disclosure Schedule shall not be deemed to be an
acknowledgment that such matter is material or outside the ordinary course of
business of the disclosing party. Disclosure of any matter or event in any of
the schedules included in Disclosure Schedule shall be deemed disclosure for
purposes of any and all other schedules included therein without the need of
specific cross reference or duplication, provided, however, that disclosure of
an agreement or other document in a listing of agreements or documents without
any summary or description of


                                      -26-

<PAGE>   34



the substance thereof shall be deemed disclosure only for purposes of the
schedule in which such agreement or other document is listed.

              (d)   Updates. Prior to the Closing Date, each party shall, to the
extent a matter required to be reported occurs, update its Disclosure Schedule
on a monthly basis by written notice to the other to reflect any matters which
have occurred from and after the date of this Agreement which, if existing on
the date of this Agreement, would have been required to be described in the
Disclosure Schedule. If requested by the recipient within 14 calendar days after
receipt by it of an update to the other's Disclosure Schedule, the party
providing the update shall meet and discuss with the recipient any update to the
Disclosure Schedule which, in the reasonable judgment of the recipient, has or
may reasonably be expected to have a Material Adverse Effect on the disclosing
party or which may in any manner be materially adverse to the recipient (a
"Disclosure Schedule Change").

       3.3    Duties Concerning Representations. Each party to this Agreement
shall: (a) to the extent within its control, use best efforts to cause all of
its representations and warranties contained in this Agreement to be true and
correct in all respects at the Effective Time with the same force and effect as
if such representations and warranties had been made on and as of the Effective
Time; and (b) use best efforts to cause all of the conditions precedent set
forth in Article VII of this Agreement to be satisfied. Neither party shall take
any action, nor agree to commit to take any action, which would or reasonably
can be expected to: (i) adversely affect the ability of either Mutual or First
Northern to obtain the Regulatory Approvals; (ii) adversely affect a party's
ability to perform its covenants or agreements under this Agreement; or (iii)
result in any of the conditions to the Merger set forth in Article VII not being
satisfied.

       3.4    Deliveries of Information; Consultation. From time to time prior
to the Effective Time, and subject to the limitations on access rights under
Section 3.1 of this Agreement and to the Confidentiality Agreement:

              (a)   Deliveries. First Northern and Mutual shall furnish promptly
to the other: (i) a copy of each significant report, schedule and other document
filed by or received by it or its Subsidiaries pursuant to the requirements of
federal or state securities or financial institution Laws or any other
applicable Laws promptly after such documents are available; (ii) its
consolidated monthly financial statements (as prepared in accordance with its
normal accounting procedures) promptly after such financial statements are
available; (iii) a summary of any action taken by its, or its Subsidiaries',
Boards of Directors, or any committee thereof; and (iv) all other significant
information concerning its and its Subsidiaries' business, properties and
personnel as the other may reasonably request.

              (b)   Consultation. Representatives of First Northern and Mutual
shall confer and consult with one another on a regular and frequent basis to
report on operational matters and the general status of First Northern's and
Mutual's ongoing business operations.



                                      -27-

<PAGE>   35



              (c)   Regulatory Matters. Representatives of First Northern and
Mutual shall discuss with one another any matters directly affecting them in
which any state or federal regulator of First Northern or Mutual or any of their
Subsidiaries, is involved.

              (d)   Litigation. Each party to this Agreement shall provide
prompt notice to the other party of any litigation, arbitration, proceeding,
governmental investigation, citation or action of any kind which may be
commenced, threatened or proposed by any Person concerning the legality,
validity or propriety of the transactions contemplated by this Agreement. If any
such litigation is commenced against any party to this Agreement, the parties
shall cooperate in all respects in connection with such litigation.

       3.5    Directors' and Officers' Indemnification and Insurance.

              (a)   Survivor's Indemnification. From and after the Effective
Time, Survivor shall indemnify, defend and hold harmless each person who is now,
or has been at any time prior to the date hereof or who becomes prior to the
Effective Time, an officer, director or employee of First Northern or any First
Northern Subsidiary (the "Indemnified Parties") against all losses, claims,
damages, costs, expenses, liabilities or judgments or amounts that are paid in
settlement with the approval of Survivor (which approval shall not be
unreasonably withheld) of or in connection with any claim, action, suit,
proceeding or investigation which is based in whole or in part on or arising in
whole or in part out of the fact that such person is or was a director, officer
or employee of First Northern or any First Northern Subsidiary, whether
pertaining to any matter existing or occurring at or prior to the Effective
Time, but only if filed, initiated, asserted or claimed prior to, or at or
within five years after, the Effective Time ("Indemnified Liabilities"),
including all Indemnified Liabilities based in whole or in part, or arising in
whole or in part out of, or pertaining to, this Agreement or the transactions
contemplated hereby, in each case to the full extent First Northern would have
been permitted under the WBCL and First Northern's Articles of Incorporation and
Bylaws (as amended and in effect as of the date of this Agreement) to indemnify
such person, and Survivor shall pay expenses in advance of the final disposition
of any such action or proceeding to each Indemnified Party to the full extent
permitted by Law upon receipt of any affirmation and undertaking required by
Section 180.0853 of the WBCL. Without limiting the foregoing, in the event any
such claim, action, suit, proceeding or investigation is brought against any
Indemnified Party (whether brought before or within five years after the
Effective Time): (x) any counsel retained by the Indemnified Parties for any
period after the Effective Time shall be reasonably satisfactory to Survivor;
(y) after the Effective Time, Survivor shall pay all reasonable fees and
expenses of such counsel for the Indemnified Parties promptly as statements
therefor are received; and (z) after the Effective Time, Survivor will use all
reasonable efforts to assist in the vigorous defense of any such matter,
provided that Survivor shall not be liable for any settlement of any claim
effected without its written consent, which consent, however, shall not be
unreasonably withheld. Any Indemnified Party wishing to claim indemnification
under this Section 3.5, upon learning of any such claim, action, suit,
proceeding or investigation, shall notify Survivor (but the failure so to notify
Survivor shall not relieve it from any liability which it may have under this
Section 3.5 except to the extent such failure materially prejudices such party),
and shall deliver to Survivor the affirmation and undertaking,


                                      -28-

<PAGE>   36



if any, required by Section 180.0853 of the WBCL. The Indemnified Parties as a
group may retain only one law firm to represent them with respect to each such
matter unless there is, under applicable standards of professional conduct, a
conflict on any significant issue between the positions of any two or more
Indemnified Parties.

              (b)   Director and Officer Insurance. Survivor shall use
reasonable efforts to obtain, after the Effective Time, directors' and officers'
liability insurance coverage for the officers and directors of Survivor, for
itself or as part of an affiliated group with MHC, to the extent that the same
is economically practicable. Such insurance shall cover directors and officers
of the Bank to the same extent as it covers directors and officers of other
subsidiaries of Survivor or MHC.

              (c)   Parties Benefitted. The provisions of this Section 3.5 are
intended to be for the benefit of, and shall be enforceable by, each Indemnified
Party, his or her heirs and his or her representatives, and shall survive the
Effective Time and any merger, consolidation or reorganization of Survivor,
including the Restructuring.

       3.6    Letters of Accountants. First Northern shall use its best efforts
to cause to be delivered to Mutual a letter of Wipfli Ullrich Bertelson LLP,
First Northern's independent auditors, dated a date within three business days
before the date on which the Registration Statement is declared effective, and
addressed to Mutual, in form and substance reasonably satisfactory to Mutual and
customary in scope and substance for letters delivered by independent public
accountants in connection with registration statements similar to the
Registration Statement and proxy statements similar to the Proxy Statement.
Mutual shall use its best efforts to cause to be delivered to First Northern a
letter of Ernst & Young LLP, Mutual's independent auditors, dated a date within
three business days before the date on which the Registration Statement is
declared effective, and addressed to Mutual and First Northern, in form and
substance reasonably satisfactory to Mutual and First Northern and customary in
scope and substance for letters delivered by independent public accountants in
connection with registration statements similar to the Registration Statement
and proxy statements similar to the Proxy Statement.

       3.7    Legal Conditions to Merger. Each party to this Agreement will: (a)
take all reasonable actions necessary to comply promptly with all legal
requirements which may be imposed on it with respect to the Merger (including
making all filings and requests in connection with the Regulatory Approvals and
furnishing all information required in connection therewith); (b) promptly
cooperate with and furnish information to the other party in connection with any
such requirements imposed upon any of them in connection with the Merger; and
(c) take all reasonable actions necessary to obtain (and will cooperate with the
other party in obtaining) any consent, authorization, order or approval of, or
any exemption by, any governmental entity or other public or private Person,
required to be obtained by the parties to this Agreement in connection with the
Merger or the taking of any action contemplated thereby or by this Agreement.



                                      -29-

<PAGE>   37



       3.8    Stock Listings. First Northern shall use its best efforts to
maintain the listing of First Northern Common Stock on the NASDAQ/NMS through
the Effective Time. It is the intention of the parties that by taking this
action First Northern Shareholders will not be entitled to any dissenters' or
appraisal rights under applicable Law as a result of the Merger and the
transactions contemplated by this Agreement.

       3.9    Announcements. Subject to each party's disclosure obligations
imposed by Law, First Northern and Mutual will cooperate with each other in the
development and distribution of all news releases and other public information
disclosures with respect to this Agreement or any of the transactions
contemplated hereby and shall not issue any public Announcement or statement
with respect thereto prior to consultation with the other party.

       3.10   Best Efforts. Subject to the terms and conditions of this
Agreement and subject to the fiduciary duties of the Board of Directors of each
party, each of the parties agrees to use its best efforts to take, or cause to
be taken, all action and to do, or cause to be done, all things necessary or
advisable to consummate the transactions contemplated by this Agreement.

       3.11   Employee And Managerial Matters.

              (a)   Employees. The Bank will continue to employ substantially
all present employees who are employed without employment contracts as employees
at will, subject to the determinations of Bank management and the Bank's and
Survivor's boards of directors.

              (b)   Survivor Executive Officers. Promptly after the Effective
Time, the Survivor Board of Directors shall meet to elect additional executive
officers of Survivor so that at least 40% of the Survivor executive officers are
executive officers of First Northern prior to the Effective Time. Such
individuals shall be designated by Mutual prior to the time the Proxy Statement
is mailed to First Northern Shareholders.

              (c)   First Northern Replacement Employment Agreements. The Bank
shall, with respect to each of the First Northern Executives who is a party to a
First Northern Existing Employment Agreement, use its best efforts to cause them
to enter into a First Northern Replacement Employment Agreement; provided,
however, that the First Northern Existing Employment Agreement of the chief
executive officer of First Northern shall be retained subject to the provisions
of Section 7.2(h) hereof.

              (d)   Bank Officers and Directors. As of the Effective Time, the
directors and executive officers of the Bank shall continue to be those persons
serving in such capacities prior to the Effective Time. Promptly thereafter, the
chief executive officer of Mutual shall be elected as an additional director of
the Bank. In addition, promptly thereafter, the chief executive officer of First
Northern shall be elected as an additional director of the Stock Bank.



                                      -30-

<PAGE>   38



       3.12   Employee Benefit Matters.

              (a)   First Northern Stock Option Plans. Prior to the Effective
Time, First Northern shall take any and all actions necessary so that, effective
as of the Effective Time, the First Northern Stock Option Plans will be
terminated, there shall be no outstanding stock options of First Northern (other
than the Stock Option Agreement), and any and all shares reserved for issuance
in connection with the exercise of options granted under any such First Northern
Stock Option Plan (including those reserved for issuance upon the exercise of
First Northern Stock Options granted prior to, and outstanding as of, the
Effective Time) shall be free of all restrictions associated with such
reservation and shall constitute authorized and unissued shares of First
Northern Common Stock; provided, however, that any and all shares subject to
First Northern Stock Options that are exercised prior to the Effective Time
shall not be deemed to constitute authorized and unissued shares of First
Northern Common Stock.

              (b)   First Northern 401(k) Plan. The First Northern 401(k)
Retirement Plan shall continue, except to the extent inconsistent with Law,
after the Merger for employees of Bank until such time as it is combined with,
or replaced by, a retirement or similar benefit plan covering employees of all
Affiliates of MHC. For purposes of determining eligibility to participate and
vesting under the Survivor's 401(k) plan or a 401(k) plan covering employees of
all Affiliates of MHC, service with First Northern or an Affiliate of First
Northern shall be treated as service with MHC; provided, however, that such
service shall not be recognized to the extent that such recognition would result
in a duplication of benefits.

              (c)   Health and Welfare Benefits. After the Merger, Survivor
shall continue, except to the extent not consistent with Law, the Bank's health
and welfare benefit plans, programs, insurance and policies, until such time as
they are replaced by programs or benefits common to all employees of Affiliates
of MHC; provided, however, no coverage of any of the Bank's continuing employees
or their dependents shall terminate under any of the Bank's health and welfare
benefit plans, programs, insurance and policies prior to the time such employees
and dependents become eligible to participate in the programs and benefits
common to substantially all employees of Affiliates of MHC and their dependents.

              (d)   Replacement. With respect to each employee and health and
welfare benefit plan or program that replaces a First Northern Existing Plan,
for purposes of determining eligibility to participate and vesting, service with
First Northern or an Affiliate of First Northern shall be treated as service
with Survivor; provided, however, that such service shall not be recognized to
the extent that such recognition would result in a duplication of benefits. Such
service shall also apply for purposes of satisfying any waiting periods,
actively-at-work requirements, and evidence of insurability requirements. No
pre-existing condition limitations will apply to any of the Bank's employees or
their dependents who were participants in the First Northern Existing Plans
comparable to the plan in question at the Closing Date. Each of the Bank's
continuing employees and their dependents shall be given credit for amounts paid
under a corresponding benefit plan during the same period for purposes of
applying deductibles,


                                      -31-

<PAGE>   39



co-payments and out-of-pocket maximums as though such amounts had been in
accordance with the terms and conditions of the corresponding First Northern
Existing Plan.

              (e)   COBRA. Until the Effective Time, First Northern shall be
liable for all obligations for continued health coverage pursuant to Section
4980B of the Code and Sections 601 through 609 of ERISA ("COBRA") with respect
to each First Northern qualifying beneficiary (as defined in COBRA) who incurs a
qualifying event (as defined in COBRA) before the Effective Time. Survivor shall
be liable for (i) all obligations for continued health coverage under COBRA with
respect to each First Northern qualified beneficiary (as defined in COBRA) who
incurs a qualifying event (as defined in COBRA) from and after the Effective
Time, and (ii) for continued health coverage under COBRA from and after the
Effective Time for each First Northern qualified beneficiary who incurs a
qualifying event before the Effective Time.

       3.13   Conformance to Reserve Policies. First Northern shall cause the
Bank to establish such additional accruals and reserves as may be necessary, in
the reasonable judgment of Mutual, to conform the Bank's general valuation
allowances to Mutual's asset classification policy, as well as to reflect the
costs and expenses of First Northern with respect to the Merger and the other
transactions contemplated by this Agreement; provided, however, that First
Northern shall not be required to cause the Bank to take any such action until
the Regulatory Approvals have been received, shareholders have approved this
Agreement and the Merger at the meeting specified in Section 2.12 of this
Agreement and First Northern is reasonably satisfied that the Merger will be
consummated. First Northern's representations, warranties and covenants
contained in this Agreement shall not be deemed to be untrue or breached in any
respect for any purpose nor shall any condition set forth in Section 7.2 of this
Agreement be considered unsatisfied as a consequence of any modification or
changes undertaken by the Bank, after notice to and non-objection by Mutual, in
order for First Northern to comply with the requirements of this Section 3.13.

       3.14   Conduct of Mutual's Business and Authorization, Reservation and
Listing of Common Stock. Mutual will maintain its corporate existence in good
standing and conduct its business so as to be able to consummate the
transactions contemplated by the Agreement. Mutual shall, in the event it
becomes aware of the impending or threatened occurrence of any event or
condition which would cause or constitute a breach (or would have caused or
constituted a breach had such event occurred or been known prior to the date
hereof) of any of its representations, warranties, covenants or agreements
contained or referred to herein or which would or would be reasonably likely to
cause Mutual not to be able to satisfy any condition set forth in Sections 7.1
or 7.3 of this Agreement, give prompt written notice thereof to First Northern
and use its best efforts to prevent or promptly remedy the same. By appropriate
resolution, the Board of Directors of Survivor shall, prior to the Effective
Time, authorize and reserve the required number of shares of Survivor Common
Stock to be issued pursuant to this Agreement. Survivor also shall use all
reasonable efforts to cause the shares of Survivor Common Stock to be issued
pursuant to this Agreement to be approved for listing on the NASDAQ/NMS subject
to official notice of issuance, prior to the Effective Time.



                                      -32-

<PAGE>   40
         3.15 Affiliates. Not later than 10 calendar days after the date of the
First Northern Meeting, First Northern shall deliver to Mutual a letter
identifying, to the best of First Northern's Knowledge, all Persons who were
Affiliates at the date of the First Northern Meeting. First Northern shall
furnish such information and documents as Mutual may reasonably request for the
purposes of reviewing such list. First Northern shall advise the Affiliates of
the resale restrictions imposed by applicable securities Laws and shall use
reasonable best efforts to obtain from the Affiliates an executed Affiliate
Letter for delivery to Mutual prior to or at the Closing.


                                   ARTICLE IV
                REPRESENTATIONS AND WARRANTIES OF FIRST NORTHERN

         First Northern hereby represents and warrants to Mutual and Merger
         Corp. that:

         4.1      Organization and Qualification; Subsidiaries.

                  (a) First Northern is a corporation duly organized, validly
existing and in active status under the Laws of the State of Wisconsin, and is a
registered savings and loan holding company under HOLA. The Bank is a Wisconsin
capital stock savings and loan association duly organized, validly existing and
in good standing under the Laws of the state of Wisconsin. The deposits of the
Bank are insured by the SAIF of the FDIC as permitted by federal Law, and the
Bank has paid all premiums and assessments required thereunder. The Bank is a
member in good standing of the FHLB of Chicago. Each of the other First Northern
Subsidiaries is duly organized, validly existing and in good standing under the

possession of all franchises, grants, authorizations, licenses, permits,
easements, consents, certificates, approvals and orders ("First Northern
Approvals") necessary to own, lease and operate its properties and to carry on
its business as it is now being conducted, including appropriate authorizations
from the OTS, the FDIC and the Wisconsin Agency, except where a failure to be so
organized, existing and in good standing or to have such power, authority and
First Northern Approvals would not, individually or in the aggregate, have a
Material Adverse Effect on First Northern, and neither First Northern nor any
First Northern Subsidiary has received any notice of proceedings relating to the
revocation or modification of any First Northern Approvals.

                  (b) First Northern and each First Northern Subsidiary is duly
qualified or licensed as a foreign corporation to conduct business, and is in
good standing (or the equivalent thereof) in each jurisdiction where the
character of the properties it owns, leases or operates or the nature of the
activities it conducts make such qualification or licensing necessary, except
for such failures to be so duly qualified and licensed and in good standing that
would not, either individually or in the aggregate, have a Material Adverse
Effect on First Northern.

                  (c) A true and complete list of all Subsidiaries of First
Northern (the "First Northern Subsidiaries"), together with (i) First Northern's
direct or indirect percentage ownership

of each First Northern Subsidiary; (ii) the jurisdiction in which the First
Northern Subsidiaries are incorporated; and (iii) a description of the principal
business activities conducted by each First Northern Subsidiary, is set forth in
the First Northern Disclosure Schedule. Except as set forth in the First
Northern Disclosure Schedule, First Northern and/or one or more of the First
Northern Subsidiaries owns beneficially and of record all of the outstanding
shares of capital stock of each of the First Northern Subsidiaries. Except for
the Subsidiaries identified in the First Northern Disclosure Schedule, First
Northern does not directly or indirectly own any equity or similar interests in,
or any interests convertible into or exchangeable or exercisable for any equity
or similar interest in, any corporation, partnership, limited liability company,
joint venture or other business association or entity other than in the ordinary
course of business, and in no event in excess of 10% of the outstanding equity
or voting securities of such entity.

         4.2 Articles of Incorporation and Bylaws. First Northern heretofore has
furnished to Mutual a complete and correct copy of the Articles of Incorporation
and Bylaws, as amended or restated, of First Northern and of each First Northern
Subsidiary. Such Articles of Incorporation and Bylaws are in full force and
effect. Neither First Northern nor any First Northern Subsidiary is in violation
of any of the provisions of its Articles of Incorporation or Bylaws.

         4.3 Capitalization. The authorized capital stock of First Northern
consists of 30,000,000 shares of First Northern Common Stock and 10,000,000
shares of cumulative preferred stock, par value $1.00 per share. As of February
15, 2000, (a)8,586,308 shares of First Northern Common Stock are issued and
outstanding, all of which are duly authorized, validly issued, fully paid and

                       CONDITIONS PRECEDENT TO THE MERGER

         7.1 Conditions to Each Parties Obligations to Effect the Merger. The
respective obligations of Mutual and First Northern to effect the transactions
contemplated by this Agreement shall be subject to the fulfillment at or prior
to the Closing and as of the Effective Time of the following conditions
precedent:

                  (a) No Litigation. No suit, action or other proceeding shall
be pending or overtly threatened before any court in which the consummation of
the transactions contemplated by this Agreement is restrained or enjoined or in
which the relief requested is to restrain, enjoin or prohibit the consummation

the reasonable judgment of either Mutual or First Northern, such suit, action or
other proceeding, is likely to have a material adverse effect with respect to
such party's interest.

                  (b) Approval of First Northern Shareholders. This Agreement
and the Merger shall have received the requisite approval and authorization of
the First Northern Shareholders.

                  (c) Regulatory Approvals.

                     (i) The Merger, this Agreement, the transactions
contemplated hereby, shall have been approved by the OTS, the FDIC, the
Wisconsin Agency, and any other governmental entities whose approval is
necessary, all conditions required to be satisfied prior to the Effective Time
imposed by the terms of such approvals shall have been satisfied, and all


                                      -54-

<PAGE>   62



waiting periods relating to such approvals shall have expired. The
Restructuring, except for the step set forth in Section 2.14(b) of this
Agreement which shall not be a condition precedent to completion of the Merger,
also shall have been approved by the OTS, the FDIC and the Wisconsin Agency, and
any other governmental entity whose approval is necessary in order for Mutual to
proceed with the Restructuring.

                           (ii) No permission, approval, determination, consent
or waiver received pursuant to Section 7.1(c)(i) of this Agreement shall contain
any condition applicable to Mutual which is, in the reasonable judgment of
Mutual, materially burdensome upon the conduct of Mutual's business or which
would so adversely impact the economic and business benefits of the Merger or
the Restructuring to Mutual so as to render it inadvisable to proceed with the
Merger or the Restructuring.

                  (d) Restructuring. The Restructuring shall have occurred,
except for any part thereof which can occur only simultaneously with or
subsequent to the Merger and the step set forth in Section 2.14(b) of the

First Northern of its assets to Merger Corp. pursuant to the Merger and, as
described in the definition of the Restructuring, the transfer by MHC of the
stock of Stock Bank to Merger Corp. and the issuance of shares of stock of
Merger Corp. to the public for cash will be treated for federal income tax
purposes as a transaction within the provisions of ss. 351(a) of the Code and
(b) an opinion of Quarles & Brady LLP that the Merger will constitute a
reorganization within the meaning of ss. 368(a) of the Code.

                  (f) NASDAQ/NMS. Shares of Survivor Common Stock shall have

                  (b) Proceedings and Instruments Satisfactory. All proceedings,
corporate or other, to be taken in connection with the transactions contemplated
by this Agreement, and all documents incident thereto, shall be reasonably
satisfactory in form and substance to Mutual, and First Northern shall have made

<PAGE>   63



correct copies of all documents Mutual may reasonably request in connection with
the transactions contemplated by this Agreement.

                  (c) Representations and Warranties of First Northern. Each of
the representations and warranties of First Northern contained in Article IV of
this Agreement, after giving effect to any update to the First Northern
Disclosure Schedule Change, shall be true and correct, as of the Effective Time
with the same force and effect as though made on and as of the Effective Time,
except for those representations and warranties which address matters only as of
a particular date (which shall remain true and correct as of such date), and
except for those breaches which individually or in the aggregate do not or would
not be reasonably likely to have a Material Adverse Effect on First Northern.

                  (d) No Material Adverse Change. During the period from the
date of this Agreement to the Closing Date and as of the Effective Time there
shall not have occurred, and there shall not exist on the Closing Date and as of
the Effective Time, any condition(s) or fact(s) having individually or in the
aggregate a Material Adverse Effect (irrespective of whether any such condition
or fact was disclosed in a First Northern Disclosure Schedule Change) on First
Northern.

                  (e) Deliveries at Closing. First Northern shall have delivered
to Mutual the following documents, each properly executed and dated the Closing
Date: (i) the First Northern Closing Certificate; and (ii) the First Northern
Counsel Opinion.

                  (f) Other Documents. First Northern shall have delivered to
Mutual such certificates and documents of officers of First Northern and public
officials as shall be reasonably requested by Mutual to establish the existence
of First Northern and the due authorization of this Agreement and the
transactions contemplated by this Agreement by First Northern.

                  (g) Accountant Letters. Mutual shall have received a copy of
each of the following letters from Wipfli Ullrich Bertelson LLP, each of which

the letter described in Section 3.6 of this Agreement; (ii) a similar letter
dated the Closing Date.

                  (h) First Northern Replacement Employment Agreements. Except
with respect to First Northern's chief executive officer and up to two
additional First Northern Executives, First Northern shall have delivered to
Mutual, with respect to each of the First Northern Executives who have First
Northern Existing Employment Agreements in effect on the Closing Date, a First
Northern Replacement Employment Agreement in each case dated as of the Closing
Date and executed on behalf of the Bank by a duly authorized officer and by the
appropriate First Northern Executive. The Chief Executive Officer of First
Northern shall have delivered to the Bank and Mutual a waiver, reasonably
acceptable in form and substance to Mutual, of the provisions of his First
Northern Existing Employment Agreement, which would create severance or other
accelerated benefits thereunder as a result of the Merger and the


                                      -56-

<PAGE>   64

prior to the Closing Date and with the written consent (if necessary) of the
First Northern Stock Option holder, cashed out each of such holder's First
Northern Stock Options without the exercise thereof at a price equal to the
difference between the Cash Value and the exercise price of such option. In the
event that a holder of a First Northern Stock Option fails to take any action,
the holder of such First Northern Stock Option shall be deemed to have agreed to
have his or her First Northern Stock Option cashed out in accordance with this
subsection 7.2(j). In recognition of the requirement that such options be
converted to cash without an ability to elect stock and not be carried forward
into the Survivor, to the extent that options are cashed out pursuant to this
section 7.2(j), First Northern may provide an additional payment equal to not
more than 25% of such difference between the Cash Value and the exercise price
of any such option; provided, however, that in no event shall the net total
amount of such additional payments, after the expected corporate tax deduction,
to all holders of First Northern Stock Options exceed $755,000. In any event, as

other than the Stock Option Agreement.

                                      -57-

<PAGE>   65



Effective Time, except for those representations and warranties which address

existence of Mutual and the due authorization of this Agreement and the
transactions contemplated by this Agreement by Mutual.

from a financial point of view and such option shall not have been withdrawn as
of the Closing Date.

to Section 3.11 of this Agreement, the Bank shall have offered to each of the
First Northern Executives who have a First Northern Existing Employment

                           TERMINATION; MISCELLANEOUS

Shareholders), as follows:

             (a) by mutual written agreement of Mutual and First Northern;

             (b) by Mutual if any of the conditions set forth in Sections
7.1 or 7.2 of this Agreement shall not have been fulfilled by the Closing, or
within 30 days after receipt of a First Northern Disclosure Schedule Change
indicating a First Northern Material Adverse Effect which cannot be reasonably
expected to be cured;

             (c) by First Northern if any of the conditions set forth in
Sections 7.1 or 7.3 of this Agreement shall not have been fulfilled by the
Closing, or within 30 days after receipt of a Mutual Disclosure Schedule Change
indicating a Mutual Material Adverse Effect which cannot be reasonably expected
to be cured;

             (d) by either Mutual or First Northern if the Closing has not
occurred on or before 11:59 p.m. on January 16, 2001.

             (e) by First Northern, upon five days' prior written notice to
Mutual, if, as a result of an Acquisition Proposal by a Person other than Mutual
or an Affiliate of Mutual, the Board of Directors of First Northern determines
in good faith and upon the written opinion of its legal counsel that its
fiduciary duties to shareholders require that such Acquisition Proposal be
accepted, but in such case subject to all of Mutual's rights hereunder and under
the Stock Option Agreement.

         8.2 Rights on Termination; Waiver. The representations, warranties,
covenants, agreements and other obligations of the parties set forth in this
Agreement shall terminate upon the termination of this Agreement pursuant to
Section 8.1 hereof, except that the agreements set forth in Section 3.1, and
Article VIII of this Agreement shall survive any such termination indefinitely,
and each party to this Agreement shall retain any and all remedies which it may
have for breach of contract provided by Law based on another party's willful
failure to comply with the terms of this Agreement. If any of the conditions set
forth in Sections 7.1 and 7.2 of this Agreement have not been satisfied, Mutual
may nevertheless elect to proceed with the consummation of the transactions
contemplated by this Agreement and if any of the conditions set forth in
Sections 7.1 and 7.3 of this Agreement have not been satisfied, First Northern
may nevertheless elect to proceed with the consummation of the transactions
contemplated by this Agreement. Any such election to proceed shall be evidenced
by a certificate signed on behalf of the waiving party by an officer of that

         8.3 Survival of Representations, Warranties and Covenants. The
representations, warranties, covenants, agreements and other obligations of the

except the covenants, agreements, and other obligations of the parties which by

shall survive the Effective Time indefinitely.

         8.4 Entire Agreement; Amendment. This Agreement, the Stock Option
Agreement, the Confidentiality Agreement and the other documents referred to in
this Agreement and required to be delivered pursuant to this Agreement
constitute the entire agreement among the parties pertaining to the subject
matter of this Agreement, and supersede all prior and contemporaneous
agreements, understandings, negotiations and discussions of the parties, whether
oral or written, and there are no warranties, representations or other
agreements between the parties in connection with the subject matter of this
Agreement, except as specifically set forth in this Agreement. This Agreement
may be amended by the parties at any time before or after approval of this
Agreement by the First Northern Shareholders, except that after such approval no
amendment shall be made without the further approval of the First Northern
Shareholders if such amendment: (a) reduces the consideration to be received by
First Northern Shareholders; or (b) otherwise materially adversely affects the
rights of the First Northern Shareholders. No amendment, supplement,
modification, waiver or termination of this Agreement shall be binding unless
executed in writing by the party to be bound thereby. No waiver of any of the
provisions of this Agreement shall be deemed or shall constitute a waiver of any
other provision of this Agreement, whether or not similar, nor shall such waiver
constitute a continuing waiver unless otherwise expressly provided.

         8.5 Expenses. All costs and expenses incurred in connection with this
Agreement and the transactions contemplated by this Agreement shall be paid by
the party incurring such expenses. The First Northern Disclosure Schedule and
Mutual Disclosure Schedule includes an estimate by First Northern and Mutual,
respectively, of all costs and expenses incurred or to be incurred by each in
connection with the transactions contemplated by this Agreement. Notwithstanding
the foregoing, in the event Mutual terminates this Agreement pursuant to Section
8.1(b) on account of First Northern having willfully breached one or more of the
conditions set forth in Section 7.2(a) or 7.2(c) of this Agreement, or if First
Northern terminates this Agreement pursuant to Section 8.1(c) hereof on account
of Mutual having willfully breached one or more of the conditions set forth in
Section 7.3(a) or 7.3(c) of this Agreement, then, in addition to any other
rights or remedies such party (the "non-breaching party") shall have against the
other party (the "breaching party") under this Agreement or at law or in equity,
the non-breaching party shall have the right to recover from the breaching
party, up to $500,000 in the case of First Northern's expenses and up to $1.4
million in the case of, Mutual's expenses, all reasonable and necessary expenses
incurred by the non-breaching party exclusively for the purpose of entering into
this Agreement and consummating the transactions contemplated hereby. In
addition, Mutual shall be reimbursed for its expenses, as provided above, in
addition to its other remedies in the event that First Northern terminates this
Agreement pursuant to Section 8.1(e) hereof.

                             STOCK OPTION AGREEMENT


         STOCK OPTION AGREEMENT, dated as of February 21, 2000, by and between
Mutual Savings Bank, a mutual savings bank chartered under Chapter 214 of
Wisconsin Statutes ("Mutual"), and First Northern Capital Corp., a Wisconsin
corporation (the "Company").

         WHEREAS, concurrently with the execution and delivery of this
Agreement, the Company, Mutual, and OV Corp., a Wisconsin corporation ("Merger
Corp."), are entering into an Agreement and Plan of Merger, dated as of the date
hereof (the "Merger Agreement"), which provides, among other things, for the
merger of the Company with and into Merger Corp. (the "Merger"), upon the terms
and subject to the conditions thereof.

         WHEREAS, as a condition to Mutual's willingness to enter into the
Merger Agreement, Mutual has requested that the Company agree, and the Company
has so agreed, to grant to Mutual an option with respect to certain shares of
the Company's common stock, par value $1.00 ("Common Stock"), on the terms and
subject to the conditions set forth herein.

         NOW, THEREFORE, to induce Mutual to enter into the Merger Agreement,
and in consideration of the mutual covenants and agreements set forth herein and
in the Merger Agreement, the parties hereto agree as follows:

                  1. GRANT OF OPTION. Subject to the terms and conditions set
forth herein, the Company hereby grants to Mutual an irrevocable option (the
"Option") to purchase up to 1,708,675 shares of Common Stock (subject to
adjustment as set forth in Section 9 of this Agreement) (the "Option Shares") at
a per share purchase price of $9.0375 (subject to adjustment as set forth in
Section 9 of this Agreement) (the "Exercise Price"); provided, however, that in
no event shall the number of shares for which the Option is exercisable exceed
19.9% of the issued and outstanding shares of Common Stock without giving effect
to any shares subject to or issued pursuant to the Option.

                  2. EXERCISE OF OPTION. (a) Conditions to Exercise. If the
Merger Agreement has not been terminated by the Company pursuant to Section
8.1(c) thereof, Mutual may exercise the Option, in whole or in part, at any time
and from time to time, if, but only if both a Triggering Event (as defined
below) and an Exercise Event (as defined below) shall have occurred prior to the
occurrence of an Exercise Termination Event (as defined below). Each of the
following shall be an "Exercise Termination Event": (i) the Effective Time of
the Merger, (ii) termination of the Merger Agreement in accordance with the
provisions thereof if such termination occurs prior to the occurrence of a
Triggering Event; or (iii) the passage of 12 months after termination of the
Merger Agreement if such termination follows the occurrence of a Triggering
Event, provided that if a Triggering Event continues or occurs beyond such
termination, the Exercise Termination Event shall be 12 months from the
occurrence of the Last Triggering Event but in no event more than 18 months
after the First Triggering Event. The "Last Triggering Event" shall mean the
latest Triggering Event to occur. The "First Triggering Event" shall mean the
first Triggering Event to occur. Mutual's rights under Section 6 shall not




<PAGE>   2



terminate upon expiration of the right to exercise the Option pursuant to this
Section 2, but shall continue until such rights may otherwise terminate in
accordance with the terms of Section 6. Any date Mutual exercises its rights
under Section 6 shall be referred to herein as an "Election Date."
Notwithstanding the expiration of the Option, Mutual shall be entitled to
purchase those Option Shares with respect to which it has exercised the Option
in accordance with the terms hereof prior to the occurrence of an Exercise
Termination Event. Any purchase of shares upon exercise of the Option shall be
subject to compliance with applicable law, including the Home Owners' Loan Act
of 1933 and the Regulations of the Office of Thrift Supervision ("OTS")
promulgated thereunder (together, "HOLA").

                           (b)      Triggering Event.  The term "Triggering
Event" shall mean any of the following events or transactions occurring after
the date hereof:

                                    (i)    The Company or its wholly-owned
         subsidiary, First Northern Savings Bank, SA, a state chartered savings
         and loan association ("Bank"), without having received Mutual's prior
         written consent, shall have entered into an agreement to engage in an
         Acquisition Transaction (as hereinafter defined) with any person (the
         term "person" for purposes of this Agreement shall have the meaning
         assigned thereto in Sections 3(a)(9) and 13(d)(3) of the Exchange Act,
         and the rules and regulations thereunder) other than Mutual or any of
         its affiliates, or the Board of Directors of the Company shall have
         recommended that the shareholders of the Company approve or accept any
         Acquisition Transaction other than as contemplated by the Merger
         Agreement. For purposes of this Agreement, "Acquisition Transaction"
         shall mean (x) a merger, consolidation, share exchange, or similar
         business combination transaction, involving the Company or Bank, (y) a
         purchase, lease or other acquisition of 10% or more of the assets of
         the Company or Bank, or (z) a purchase or other acquisition (including
         by way of merger, consolidation, share exchange or otherwise) of
         securities representing 10% or more of the voting power of the Company
         or Bank.

                                    (ii)   Any person other than Mutual or an
         affiliate of Mutual shall have acquired beneficial ownership or the
         right to acquire beneficial ownership of, or commenced a tender offer
         or exchange offer for, 10% or more of the outstanding shares of Common
         Stock (the term "beneficial ownership" for purposes of this Agreement
         having the meaning assigned thereto in Section 13(d) of the Exchange
         Act, and the rules and regulations thereunder);

                                    (iii)  Any person other than Mutual or an
         affiliate of Mutual shall have made a bona fide proposal to the Company
         or Bank by public announcement or written communication that is or
         becomes the subject of public disclosure to engage in an Acquisition
         Transaction;

                                    (iv)   After a proposal is made by a third
         party to the Company or Bank to engage in an Acquisition Transaction,
         the Company shall have breached any covenant or obligation contained in
         the Merger Agreement and such breach (x) would


                                       -2-

<PAGE>   3



         entitle Mutual to terminate the Merger Agreement and (y) shall not have
         been cured prior to the Notice Date (as defined below); or

                                    (v)    Any person other than Mutual or an
         affiliate of Mutual, other than in connection with a transaction to
         which Mutual has given its prior written consent, shall have filed an
         application or notice with the OTS or the Federal Deposit Insurance
         Corporation ("FDIC") or other federal or state bank regulatory
         authority, which application or notice has been accepted for
         processing, for approval to engage in an Acquisition Transaction.

                           (c)      Exercise Event.  The term "Exercise Event"
shall mean either of the following events or transactions occurring after the
date hereof:

                                    (i)    The acquisition by any person of
         beneficial ownership of 20% or more of the then outstanding Common
         Stock without giving effect to any shares subject to or issued pursuant
         to the Option; or

                                    (ii)   The occurrence of the Triggering
         Event described in clause (i) of subsection (b) of this Section 2,
         except that the percentage referred to in clause (z) shall be 20%.

                           (d)      Notice by Company of Triggering and Exercise
Events. The Company shall notify Mutual promptly in writing of the occurrence of
any Triggering Event or Exercise Event, it being understood that the giving of
such notice by the Company shall not be a condition to the right of Mutual to
exercise the Option.

                           (e)      Exercise Procedures and Closing.  In the
event Mutual wishes to exercise the Option, it shall send to the Company a
written notice (the date of which being herein referred to as the "Notice Date")
specifying (i) the total number of Option Shares it intends to purchase pursuant
to such exercise and (ii) a place and date not earlier than three business days
nor later than 30 business days from the Notice Date for the closing of such
purchase (the "Closing Date"); provided that, if the closing of the purchase and
sale pursuant to the Option (the "Closing") cannot be consummated by reason of
any applicable judgment, decree, order, 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 or consummation has expired or been terminated;
and provided further, without limiting the foregoing, that if prior notification
to or approval of the OTS, the FDIC or any other regulatory authority is
required in connection with such purchase, Mutual shall promptly file the
required notice or application for approval and shall expeditiously process the
same (and the Company shall fully cooperate with Mutual 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, (i) any required
notification period has expired or been terminated or (ii) such approval has
been obtained, and in either event, any requisite waiting period has passed.



                                       -3-

<PAGE>   4



                           (f)      Termination of Exercise Election.
Notwithstanding Section 2(e), in no event shall any Closing Date be more than 18
months after the related Notice Date, and if the Closing Date shall not have
occurred within 18 months after the related Notice Date due to the failure to
obtain any such required approval, the exercise of the Option effected on the
Notice Date shall be deemed to have expired. In the event (i) Mutual receives
official notice that an approval of the OTS, the FDIC or any other regulatory
authority required for the purchase of Option Shares would 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 required approval,
Mutual shall be entitled to exercise its rights as set forth in Section 6 or to
exercise the Option in connection with the resale of Common Stock or other
securities pursuant to a registration statement as provided in Section 7.

                  3. PAYMENT AND DELIVERY OF CERTIFICATES. (a) Payment of
Exercise Price. On each Closing Date, Mutual shall pay to the Company in
immediately available funds by wire transfer to a bank account designated by the
Company an amount equal to the Exercise Price multiplied by the number of Option
Shares to be purchased on such Closing Date.

                           (b)      Issuance of Certificates.  At each Closing,
simultaneously with the delivery of immediately available funds as provided in
Section 3(a), the Company shall deliver to Mutual a certificate or certificates
representing the Option Shares to be purchased at such Closing, which Option
Shares shall be free and clear of all liens, claims, charges and encumbrances of
any kind whatsoever, except as provided by Section 180.0622(2)(b) of the
Wisconsin Business Corporation Law ("WBCL"), and Mutual shall deliver to the
Company a letter, in customary form, agreeing that Mutual shall not offer to
sell or otherwise dispose of such Option Shares in violation of applicable law
or the provisions of this Agreement.

                           (c)      Certificate Legend.  Certificates for the
Option Shares delivered at each Closing shall be endorsed with a restrictive
legend which shall read substantially as follows:

                  THE TRANSFER OF THE STOCK REPRESENTED BY THIS CERTIFICATE IS
                  SUBJECT TO RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF
                  1933, AS AMENDED, AND PURSUANT TO THE TERMS OF A STOCK OPTION
                  AGREEMENT DATED AS OF FEBRUARY 21, 2000. A COPY OF SUCH
                  AGREEMENT WILL BE PROVIDED TO THE HOLDER HEREOF WITHOUT CHARGE
                  UPON RECEIPT BY SELLER OR A WRITTEN REQUEST THEREFOR.

It is understood and agreed that the above legend shall be removed by delivery
of substitute certificate(s) without such legend if Mutual shall have delivered
to the Company a copy of a letter from the staff of the SEC, or an opinion of
counsel in form and substance reasonably satisfactory to the Company and its
counsel, to the effect that such legend is not required for purposes of the
Securities Act.

                  4. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
represents and warrants to Mutual that:

                     (a)      Corporate Status and Authority.  The Company
is a corporation duly organized, validly existing and in active status under the
laws of the State of Wisconsin and has the corporate power and authority to
enter into this Agreement, and subject to any regulatory approvals referred to
herein (and, with respect to Section 6 of this Agreement only, to the provisions
of Section 180.0640 of the WBCL, if applicable), to consummate the transactions
contemplated hereby.

                     (b)      Due Authorization.  The execution and
delivery of this Agreement by the Company and the consummation by the Company of
the transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of the Company and no other corporate proceedings
on the part of the Company are necessary to authorize this Agreement or any of
the transactions contemplated hereby.

                     (c)      Enforceability.  This Agreement has been
duly executed and delivered by the Company, constitutes a valid and binding
obligation of the Company and, assuming this Agreement constitutes a valid and
binding obligation of Mutual, is enforceable against the Company in accordance
with its terms.

                     (d)      Authority and Validity of Option Shares.
The Company has taken all necessary corporate action to authorize and reserve
for issuance and to permit it to issue, upon exercise of the Option, and at all
times from the date hereof through the expiration of the Option will have
reserved, authorized and unissued shares of Common Stock equal to the number of
outstanding Option Shares as adjusted pursuant to Section 9 hereof, all of
which, upon their issuance and delivery in accordance with the terms of this
Agreement, will be validly issued, fully paid and nonassessable, except as
provided in Section 180.0622(2)(b) of the WBCL.

                     (e)      Absence of Liens on Option Shares.  Upon
delivery of the Option Shares to Mutual upon the exercise of the Option, Mutual
will acquire the Option Shares free and clear of all claims, liens, charges,
encumbrances and security interests of any nature whatsoever.

                     (f)      No Conflict.  The execution and delivery of
this Agreement by the Company does not, and the consummation by the Company of
the transactions contemplated hereby will not, violate, conflict with, or result
in a breach of any provision of, or constitute a default (with or without notice
or lapse of time, or both) under, or result in the termination of, or accelerate
the performance required by, or result in a right of termination, cancellation,
or acceleration of any obligation or the loss of a material benefit under or the
creation of a lien, pledge, security interest or other encumbrance on assets
(any such conflict, violation, default, right of termination, cancellation or
acceleration, loss or creation, a "Violation") of the Company or any of its
Subsidiaries, which Violation would have a Material Adverse Effect on the
Company or Mutual.

<PAGE>   6



                  5. REPRESENTATIONS AND WARRANTIES OF MUTUAL. Mutual represents
and warrants to the Company that:

                     (a)      Corporate Status and Authority.  Mutual is a
mutual savings bank duly organized, validly existing and in good standing under
Chapter 214 of the Wisconsin Statutes and has the corporate power and authority
to enter into this Agreement and to carry out its obligations hereunder.

                     (b)      Due Authorization.  The execution and
delivery of this Agreement by Mutual and the consummation by Mutual of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Mutual and no other corporate proceedings on the
part of Mutual are necessary to authorize this Agreement or any of the
transactions contemplated hereby.

                     (c)      Enforceability.  This Agreement has been
duly executed and delivered by Mutual and constitutes a valid and binding
obligation of Mutual, and, assuming this Agreement constitutes a valid and
binding obligation of the Company, is enforceable against Mutual in accordance
with its terms.

                  6. TERMINATION ELECTION BY MUTUAL.

                     (a)      Termination Fee.  At the request of Mutual
at any time (i) commencing upon the first occurrence of an Exercise Event and
ending upon the occurrence of an Exercise Termination Event or (ii) prior to or
on the 30th business day following the occurrence of either of the events set
forth in clauses (i) and (ii) of Section 2(f), the right to exercise the Option
pursuant to Section 2 hereof, to the extent not exercised, shall terminate and
the Company (or any successor entity thereof) shall pay to Mutual the
Termination Fee. The Termination Fee (the "Termination Fee") shall be equal to
the excess, if any, of (x) the Applicable Price (as defined below) for each
share of Common Stock over (y) the Exercise Price, multiplied by the number of
Option Shares with respect to which the Option has not been exercised and, where
the Option has been exercised, in whole or in part, but the Closing Date has not
occurred, the number of Option Shares which would have been distributed at the
Closing Date. However, in no event shall the Termination Fee exceed $12.0
million.

                     (b)      Payment of Termination Fee.  If Mutual
exercises its rights under this Section 6, the Company shall, within 20 business
days after such Election Date, pay the Termination Fee to Mutual in immediately
available funds, and, as of the date of and upon such payment, the right to
exercise the Option pursuant to Section 2 hereof shall terminate.
Notwithstanding the foregoing, to the extent that prior notification to or
approval of the OTS, the FDIC or other regulatory authority is required in
connection with the payment of all or any portion of the Termination Fee, the
Company shall deliver from time to time that portion of the Termination Fee that
it is not then so prohibited from paying and shall promptly file the required
notice or application for approval and shall expeditiously process the same (and
Mutual shall cooperate with the Company in the filing of any such notice or
application and the obtaining of


                                       -6-

<PAGE>   7



any such approval), and the period of time that otherwise would run pursuant to
the preceding sentence for the payment of the portion of the Termination Fee
requiring such notification or approval shall run instead from the date on
which, as the case may be, (i) any required notification period has expired or
been terminated or (ii) such approval has been obtained and, in either event,
any requisite waiting period shall have expired. If the OTS, the FDIC or any
other regulatory authority prohibits payment of any part of the Terminate Fee,
the Company shall promptly give notice of such fact to Mutual and Mutual shall
thereafter have the right to exercise the Option as to the number of Option
Shares for which the Option was exercisable at such Election Date less the
number of shares as to which a Termination Fee has been delivered pursuant to
Section 6(a); provided that, if the Option shall have expired pursuant to
Section 2 hereof prior to the date of such notice or shall be scheduled to
expire at any time before the expiration of a period ending on the thirtieth
(30th) business day after such date, Mutual shall nonetheless have the right so
to exercise the Option pursuant to Section 2 hereof until the expiration of such
period of 30 business days.

                     (c)      Applicable Price.  For purposes of this
Agreement, the "Applicable Price" means the highest of (i) the highest price per
share at which a tender or exchange offer has been made for shares of Common
Stock after the date of this Agreement and on or prior to such Election Date,
(ii) the price per share to be paid by any third party for shares of Common
Stock or the consideration per share to be received by holders of Common Stock,
in each case pursuant to an agreement for a merger or other business combination
transaction with the Company entered into on or prior to such Election Date or
(iii) the highest bid price per share as quoted on the NASDAQ/NMS (or, if the
shares of Common Stock are no longer quoted thereon, on the principal trading
market on which such shares are traded as reported by a recognized source)
during the 30 business days preceding such Election Date. If the consideration
to be offered, paid or received pursuant to either of the foregoing clauses (i)
or (ii) shall be other than in cash, the value of such consideration shall be
determined in good faith by an investment banking firm selected by Mutual and
reasonably acceptable to the Company, which determination shall be conclusive
for all purposes of this Agreement.

                  7. REGISTRATION RIGHTS. The Company shall, if requested by
Mutual at any time and from time to time (a) within three years of the first
exercise of the 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(f) or
receipt by Mutual of official notice that an approval of the OTS, the FDIC or
any other regulatory authority required to complete the transactions
contemplated by Section 6 hereof would not be issued or granted, 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 Common Stock or other
securities that have been acquired by or are issuable to Mutual upon exercise of
the Option in accordance with the intended method of sale or other disposition
stated by Mutual, including a "shelf" registration statement under Rule 415
under the Securities Act or any successor provision, and the Company shall use
its best efforts to qualify such shares or other securities under any applicable
state securities laws. Mutual agrees to use all reasonable efforts to cause, and
to cause any underwriters of any sale or other disposition to cause, any sale or
other disposition pursuant to


                                       -7-

<PAGE>   8



such registration statement to be effected on a widely distributed basis so that
upon consummation thereof no purchaser or transferee shall own beneficially 5%
or more of the then outstanding voting power of the Company. The Company 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 120 days from the day such registration statement first becomes
effective as may be reasonably necessary to effect such sale or other
disposition. In the event that Mutual requests the Company to file a
registration statement following the failure to obtain a required approval for
an exercise of the Option as described in Section 2(f), the closing of the sale
or other disposition of Common Stock or other securities pursuant to such
registration statement shall occur substantially simultaneously with the
exercise of the Option. The obligations of the Company hereunder to file a
registration statement and to maintain its effectiveness may be suspended for
one or more periods of time not exceeding 90 days in the aggregate if the Board
of Directors of the Company shall have determined that the filing of such
registration statement or the maintenance of its effectiveness would require
disclosure of nonpublic information that would materially and adversely affect
the Company, provided that the option/exercise period shall be extended during
any such period. Any registration statement prepared and filed under this
Section 7, and any sale covered thereby, shall be at the Company's expense
except for underwriting discounts or commissions, brokers' fees and the fees and
disbursement of Mutual's counsel related thereto. Mutual shall provide all
information reasonably requested by the Company for inclusion in any
registration statement to be filed hereunder. If, during the time periods
referred to in the first sentence of this Section 7, the Company effects a
registration under the Securities Act of Common Stock for its own account or for
any other shareholders of the Company (other than on Form S-4 or Form S-8, or
any successor form), it shall allow Mutual the right to participate in such
registration, and such participation shall not affect the obligation of the
Company to effect two registration statements for Mutual under this Section 7;
provided that, if the managing underwriters of such offering advise the Company
in writing that in their opinion the number of shares of Common Stock requested
to be included in such registration exceeds the number which can be sold in such
offering, the Company shall include the shares requested to be included therein
by Mutual only to the extent permitted by the managing underwriters consistent
with the financing requirements of the Company. In connection with any
registration pursuant to this Section 7, the Company and Mutual shall provide
each other and any underwriter of the offering with customary representations,
warranties, covenants, indemnification and contribution in connection with such
registration.

                  8. VOTING OF OPTION SHARES. Subject to restrictions imposed
under the WBCL, if any, Mutual shall have the right to vote any Option Shares
acquired by it pursuant to this Agreement in any manner it deems appropriate, as
determined in its sole discretion. Prior to exercise of the Option, Mutual shall
have no rights to vote any shares or have any other rights as a shareholder of
First Northern.

                  9. ADJUSTMENT UPON CHANGES IN CAPITALIZATION. Without
limitation to any restriction on the Company contained in this Agreement or in
the Merger Agreement, in the


                                       -8-

<PAGE>   9



event of any change in Common Stock by reason of stock dividends, splitups,
mergers (other than the Merger), recapitalizations, combinations, exchange of
shares or the like, or the sale of Common Stock or the grant of any option for
the purchase of Common Stock to anyone other than Mutual, the type and number of
shares or securities subject to the Option, and the Exercise Price provided in
Section 1, shall be adjusted appropriately to restore to Mutual its rights
hereunder, including the right to purchase from the Company (or its successors)
shares of Common Stock representing 19.9% of the outstanding Common Stock,
without giving effect to any shares subject to or issued pursuant to the Option,
for the aggregate price calculated as of the date of this Agreement by
multiplying the number of Option Shares set forth in Section 1 by the per share
Exercise Price set forth in Section 1.

                  10. OTHER AGREEMENTS OF THE COMPANY. (a) The Company agrees:
(i) that it shall at all times until the termination of this Agreement have
reserved for issuance upon the exercise of the Option that number of authorized
and reserved shares of Common Stock equal to the maximum number of shares of
Common Stock at any time and from time to time issuable hereunder; (ii) that it
will not, by amendment of its articles of incorporation or through
reorganization, consolidation, merger, dissolution or sale of assets, or by any
other voluntary act, avoid or seek to avoid the observance or performance of any
of the covenants, stipulations or conditions to be observed or performed
hereunder by the Company; (iii) promptly to take all action as may from time to
time be required (including complying with all applications, premerger
notification, reporting and waiting period requirements specified in federal or
state law or regulations necessary before the Option may be exercised,
cooperating with Mutual in preparing such applications or notices and providing
such information to each such governmental authority as it may require) in order
to permit Mutual to exercise the Option and the Company duly and effectively to
issue shares of Common Stock pursuant to this Agreement; and (iv) to promptly
take all action provided in this Agreement to protect the rights of Mutual
against dilution.

                      (b)      This Agreement (and the Option granted
hereby) is exchangeable, without expense, at the option of Mutual, upon
presentation and surrender of this Agreement at the principal office of the
Company, for other agreements providing for Options of different denominations
entitling the holder thereof to purchase, on the same terms and subject to the
same conditions as are set forth in this Agreement, in the aggregate the same
number of shares of Common Stock purchasable under this Agreement. The terms
"Agreement" and "Option" as used in this Agreement include any agreements and
related options for which this Agreement (and the Option granted hereby) may be
exchanged. Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of this Agreement, and (in the
case of loss, theft or destruction) of reasonably satisfactory indemnification,
and upon surrender and cancellation of this Agreement, if mutilated, the Company
will execute and deliver a new Agreement of like tenor and date. Any such new
Agreement executed and delivered shall constitute a contractual obligation on
the part of the Company which is no greater than the contractual obligations
provided in this Agreement; provided, however, that such obligation shall be
offset by any rights enforceable by anyone with respect to the Agreement so
lost, stolen, destroyed or mutilated.

                  11. BINDING EFFECT; ASSIGNMENT; NO THIRD PARTY BENEFICIARIES.
This Agreement shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and permitted assigns. Except as
expressly provided for in this Agreement or the Merger Agreement, neither this
Agreement nor the rights or the obligations of either party hereto are
assignable, except by operation of law, or with the written consent of the other
party. However, upon a Triggering Event, Mutual may freely assign the Option,
and freely assign its rights and obligations under this Agreement. Nothing
contained in this Agreement, express or implied, is intended to confer upon any
person other than the parties hereto and their respective permitted assigns any
rights or remedies of any nature whatsoever by reason of this Agreement. Any
Option Shares sold by Mutual in compliance with the provisions of Section 7
shall, upon consummation of such sale, be free of the restrictions imposed with
respect to such shares by this Agreement.

                  12. SPECIFIC PERFORMANCE. The parties recognize and agree that
if for any reason any of the provisions of this Agreement are not performed in
accordance with their specific terms or are otherwise breached, immediate or
irreparable harm or injury would be caused for which money damages would not be
an adequate remedy. Accordingly, each party agrees that, in addition to other
remedies, the other party shall be entitled to an injunction restraining any
violation or threatened violation of the provisions of this Agreement. In the
event that any action should be brought in equity to enforce the provisions of
the Agreement, neither party will allege, and each party hereby waives the
defense, that there is adequate remedy at law.

                  13. ENTIRE AGREEMENT. This Agreement and the Merger Agreement
(including the exhibits and schedules thereto) constitute the entire agreement
among the parties with respect to the subject matter hereof and thereof and
supersede all other prior agreements and understandings, both written and oral,
among the parties or any of them with respect to the subject matter hereof and
thereof.

                  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 or in order to consummate the transactions contemplated hereby.

                  15. VALIDITY. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
the other provisions of this Agreement, which shall remain in full force and
effect. In the event any court or other competent authority holds any provisions
of this Agreement to be null, void or unenforceable, the parties hereto shall
negotiate in good faith the execution and delivery of an amendment to this
Agreement in order, as nearly as possible, to effectuate, to the extent
permitted by law, the intent of the parties hereto with respect to such
provision and the economic effects thereof. If for any reason such court or
regulatory agency determines that the Option does not permit Mutual to acquire,
or does not require the Company to comply with Section 6 hereof with respect to
the full number of shares of Common Stock as provided in Sections 2 and 6 (as
adjusted pursuant to Section 9), it is the express intention of the Company to
allow Mutual to acquire or require the Company to comply with Section 6 hereof
with respect to such lessor number of shares as may


                                      -10-

<PAGE>   11



be permissible without any amendment or modification hereof. Each party agrees
that, should any court or other competent authority hold any provision of this
Agreement or part hereof to be null, void or unenforceable, or order any party
to take any action inconsistent herewith, or not take any action required
herein, the other party shall not be entitled to specific performance of such
provision or part hereof or to any other remedy, including but not limited to
money damages, for breach hereof or of any other provision of this Agreement or
part hereof as the result of such holding or order.

                  16. NOTICES. All notices and other communications hereunder
shall be in writing and shall be deemed given if (i) delivered personally, or
(ii) sent by reputable overnight courier service, or (iii) telecopied (receipt
electronically confirmed), or (iv) five days after being mailed by registered or
certified mail (return receipt requested) to the parties at the following

MUTUAL SAVINGS BANK WILL ACQUIRE FIRST NORTHERN CAPITAL CORP.

                Unique Transaction will Allow Two of Wisconsin's
                        Premier Savings Banks to Combine

         Milwaukee, WI - MUTUAL SAVINGS BANK, Milwaukee, WI and FIRST NORTHERN
CAPITAL CORP., Green Bay, WI (NASDAQ:FNGB) today announced that they have signed
a definitive agreement for Mutual to acquire First Northern for an acquisition
price of $15 per share. The transaction will create a financial services company
with $2.6 billion in assets and seventy offices in Wisconsin and Minnesota.

         To accomplish the transaction Mutual will reorganize into a mutual
holding company ("MHC") in which Mutual's depositors will hold all of the voting
rights. The MHC in turn will form and own the majority interest in a subsidiary
mid-tier stock holding company ("Mid-Tier HC"). The remaining shares of the
Mid-Tier HC will be offered for sale to Mutual's depositors, pursuant to the
terms of a Plan of Restructuring from Mutual Savings Bank to Mutual Holding
Company, adopted by the Mutual Board of Directors on February 21, 2000, and
issued to First Northern stockholders, along with cash, to pay the acquisition
price. First Northern will merge into the Mid-Tier HC. The MHC will be the
largest savings bank holding company in Wisconsin.

         The MHC and the Mid-Tier HC Boards of Directors will include all of the
current members of the Mutual Board and four members of the First Northern
Board. Michael T. Crowley, Jr. will be the Chief Executive Officer and Michael
D. Meeuwsen the Chief Operating Officer of the Mid-Tier HC.

         Mutual Savings Bank and First Northern Savings Bank will remain as
separate banks but become wholly owned subsidiaries of the Mid-Tier HC. Customer
deposits and loans will not be affected by the transaction and all Mutual and
First Northern offices will remain open. Mutual and First Northern believe that
this will be the first acquisition in the country to be accomplished
simultaneously with a mutual holding company formation.



<PAGE>   2




         The total value of the acquisition transaction is approximately $133
million. Under the agreement, which has been approved by both parties' Boards of
Directors, at least 40% of the total consideration to First Northern
stockholders will be in the form of stock of the Mid-Tier HC. Mutual may
increase the percentage of stock to up to 70%. The balance will be paid in cash.
First Northern stockholders will be allowed to select all cash, all stock or a
combination of cash and stock, subject to pro ration provisions of the merger
agreement. The transaction will be tax free to First Northern stockholders to
the extent they receive shares of the Mid-Tier HC.

         "This combination will significantly expand the geographic scope of
Mutual's profitable and growing Wisconsin and Minnesota franchise," said Michael
T. Crowley, Jr., Mutual's President and CEO. "We are pleased to welcome First
Northern's stockholders, customers and employees to the Mutual organization
while maintaining First Northern as a locally managed community-focused bank,"
he said.

         Michael D. Meeuwsen, President and Chief Executive Officer of First
Northern said, "This transaction allows our stockholders to receive an immediate
and substantial return on their investment, while still allowing them to
continue to invest in a much larger, statewide organization. First Northern will
continue operating with the same dedicated employees and officers in our current
bank office locations. We will be able to provide additional products and
services for our valued customers."

         The transactions are conditioned upon First Northern stockholder and
Mutual depositor approval, as well as bank regulatory agency approvals and other
customary conditions. Regulatory filings are expected to be made based on first
quarter 2000 financial results for both institutions, and the transactions are
expected to close in the third or fourth quarter of 2000. The definitive
agreement also grants Mutual an option to acquire up to 19.9% of First Northern
shares if the definitive agreement is terminated under certain circumstances and
First Northern proceeds with a different transaction.

         Mutual Savings Bank, with approximately $1.8 billion in assets at
December 31, 1999, has fifty offices throughout Wisconsin and one office in
Minnesota.

         First Northern Capital Corp., is traded on the NASDAQ National Market
under the symbol "FNGB". First Northern, with $840 million in assets at December
31, 1999, has nineteen banking offices in northeastern Wisconsin.

         First Northern stockholders and other potential investors are urged to
read the proxy statement of First Northern and the prospectus of the Mid-Tier
HC, which will be filed in the future with the Securities and Exchange
Commission, to obtain important additional information. After the documents are
filed, interested persons will be able to obtain them free at the Securities and
Exchange Commission's website at www.sec.gov. When the documents are finalized,
they will be mailed to First Northern stockholders. Copies of the prospectus
will be

available free from Mid-Tier HC and copies of the proxy statement will be
available free from First Northern.

         The discussions of potential future transactions and the effects of
those transactions in this press release are "forward-looking statements"
intended to qualify for the safe harbor from liability established by the
Private Securities Litigation Reform Act of 1995. Such forward-looking
statements are subject to certain risks and uncertainties which could cause
actual results to differ materially from those anticipated. In particular,
consummation of each of the various announced transactions is subject to a
number of conditions, including those described above. Therefore, as with any
transaction, completion cannot be assured. In addition, First Northern's
periodic filings with the Securities and Exchange Commission discuss a number of
other factors which may affect its future operations. First Northern
stockholders, Mutual depositors and other readers are urged to consider these
factors carefully in evaluating the forward-looking statements. The statements
made herein are only made as of the date of this press release and neither
Mutual nor First Northern undertakes any obligation to publicly update such
statements to reflect subsequent events or circumstances.
