                         REPORT OF INDEPENDENT AUDITORS

Board of Directors
Mutual Savings Bank

     We have audited the accompanying consolidated statements of financial
condition of Mutual Savings Bank (the Bank) and subsidiaries as of December 31,
1999 and 1998, and the related consolidated statements of income, changes in
equity and cash flows for the three years ended December 31, 1999. These
financial statements are the responsibility of the Bank's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of the Bank and
subsidiaries at December 31, 1999 and 1998, and the consolidated results of
their operations and their cash flows for three years ended December 31, 1999,
in conformity with accounting principles generally accepted in the United
States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

               (INFORMATION WITH RESPECT TO JUNE 30, 2000 AND THE
          SIX-MONTH PERIODS ENDED JUNE 30, 2000 AND 1999 IS UNAUDITED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BUSINESS

     Mutual Savings Bank (the Bank) provides a full range of financial services
to customers through its branch locations in Wisconsin. The Bank is subject to
competition from other financial institutions and is also subject to the
regulations of certain federal and state agencies and undergoes periodic
examinations by those regulatory authorities.

BASIS OF FINANCIAL STATEMENT PRESENTATION

     The consolidated financial statements have been prepared in accordance with
generally accepted accounting principles and include the accounts of the Bank
and its wholly owned subsidiaries, Lake Financial and Insurance Services (Lake),
Mutual Investment Company (MIC) and MC Development Ltd. (MD). Lake provides
investment and insurance services, MIC owns and manages an investment portfolio
for the benefit of the Bank, and MD holds, for sale, title to certain parcels of
developed and undeveloped real estate. Significant intercompany accounts and
transactions have been eliminated in consolidation.

     The unaudited consolidated financial statements as of June 30, 2000 and for
the six months then ended have been prepared in accordance with generally
accepted accounting principles for interim financial information. In the opinion
of management, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation have been included. Operating
results for the six month period ended June 30, 2000 are not necessarily
indicative of the results that may be expected for the year ending December 31,
2000.

     In preparing the consolidated financial statements, management is required
to make estimates and assumptions that affect the reported amounts of assets and
liabilities as of the date of the statement of financial condition and revenues
and expenses for the period. Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

     The Bank considers federal funds sold and interest-bearing deposits that
have original maturities of three months or less to be cash equivalents.

INVESTMENT SECURITIES AND MORTGAGE-RELATED SECURITIES

TRADING ACCOUNT ASSETS

     Trading account assets are held for resale in anticipation of short-term
market movements. Trading account assets are stated at fair value. Gains and
losses are included in net gain or loss on sales of securities and are based on
the specific identification method. There were no trading account assets at
December 31, 1999 or 1998 or June 30, 2000.

SECURITIES AVAILABLE-FOR-SALE

     Management determines the appropriate classification of debt securities at
the time of purchase. Debt securities, equity securities and investments in
mutual funds not classified as trading are classified as

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

               (INFORMATION WITH RESPECT TO JUNE 30, 2000 AND THE
          SIX-MONTH PERIODS ENDED JUNE 30, 2000 AND 1999 IS UNAUDITED)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)

available-for-sale. Available-for-sale securities are stated at fair value, with
the unrealized gains and losses, net of tax, reported in a separate component of
equity.

     The amortized cost of securities classified as available-for-sale is
adjusted for amortization of premiums and accretion of discounts to maturity, or
in the case of mortgage-backed securities, over the estimated life of the
security. Such amortization is included in interest income from investments.
Interest and dividends are included in interest income from investments.
Realized gains and losses, and declines in value judged to be
other-than-temporary are included in gain (loss) on sales of securities and are
based on the specific identification method.

     Stock of the Federal Home Loan Bank (FHLB) is carried at cost which is its
redeemable value.

LOANS HELD FOR SALE AND SALES OF LOANS

     Loans held for sale, which generally consist of current production of
certain fixed-rate first mortgage loans, are recorded at the lower of aggregate
cost or market value. Fees received from the borrower are deferred and recorded
as an adjustment of the carrying value. Loans held for sale may be transferred
to loans held for investment when the Bank has both the ability and intent to
hold the loans for the foreseeable future or until maturity. Upon transfer, any
difference between the carrying amount of the loan and its outstanding principal
balance is recognized as an adjustment to yield by the interest method.

INTEREST AND FEES ON LOANS

     Allowances of $161 (unaudited), $228 and $172 are established for accrued
but uncollected interest on mortgage loans for which any payments were more than
90 days past due at June 30, 2000 and December 31, 1999 and 1998, respectively.
Interest previously accrued on these loans is removed from income at that time.
Payments received, if any, on these loans are recorded as principal reduction or
as interest based on management's judgment as to ultimate collectibility of all
contractual future principal and interest payments.

     Loan origination and commitment fees and certain direct loan origination
costs are deferred and amortized as an adjustment of the related loans' yield.
The Bank amortizes these amounts using the level yield method over the estimated
life of the related loans.

ALLOWANCE FOR LOSSES ON LOANS

     The allowance for losses on loans is composed of general valuation
allowances. The Bank may establish a specific valuation allowance on loans it
considers impaired but in such event the loan is reduced by the amount of the
specific allowance and a corresponding amount is charged off to the allowance
for losses on loans. A loan is considered impaired when, based on current
information and events, it is probable that the Bank will not be able to collect
all amounts due according to the contractual terms of the loan agreement. When
the carrying amount of the loan exceeds (1) the present value of the expected
cash flows, discounted at the loan's original effective interest rate, or (2)
the fair value of the underlying collateral, a specific valuation allowance is
recorded for such excess. The adjusted balance of the loan is adjusted
(decreased) to reflect significant changes in the estimated fair value of
collateral, the estimated amount and timing of an impaired loan's expected
future cash flows, or if actual cash flows that differ significantly from
expected future cash flows. General valuation allowances are based on an
evaluation of the various risk components that are inherent in the credit
portfolio. The risk components that are

evaluated include past loan loss experience; the level of non-performing and
classified assets; current economic conditions; volume, growth and composition
of the loan portfolio; adverse situations that may affect borrowers' ability to
repay; the estimated value of any underlying collateral; peer group comparisons;
regulatory guidance; and other relevant factors.

     The allowance is increased by provisions charged to earnings and reduced by
charge-offs, net of recoveries. The allowance reflects management's best
estimate of the amount necessary to provide for the credit risks of the Bank.
The allowance is based on a risk model developed and implemented by management
and approved by the Bank's Board of Directors.

FORECLOSED PROPERTIES AND REPOSSESSED ASSETS

     Foreclosed properties acquired through, or in lieu of, loan foreclosure are
recorded at the lower of cost or fair value less estimated costs to sell. Costs
related to the development and improvement of property are capitalized, whereas
costs related to holding the property are expensed.

PREMISES AND EQUIPMENT

     Land, buildings, leasehold improvements and equipment are carried at
amortized cost. Buildings and furniture, equipment and automobiles are amortized
over their estimated useful lives (40 to 45 years and 3 to 10 years,
respectively) using the straight line method. Leasehold improvements are
amortized over the shorter of their useful lives or the lease terms (generally
10 years). The Bank reviews buildings, leasehold improvements and equipment for
impairment whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable. Impairment exists when the
estimated undiscounted cash flows for the property is less than its carrying
value. If identified, an impairment loss is recognized through a charge to
earnings based on the fair value of the property.

GOODWILL AND OTHER INTANGIBLE ASSETS

     Goodwill, representing the excess of purchase price over the fair value of
net assets acquired, results from acquisitions made by the Bank. The Bank's
goodwill is being amortized to operating expense using the straight-line method
over 15 years. Other intangible assets are amortized over their estimated useful
lives, generally 7-10 years. The carrying amount of goodwill and other
intangible assets are reviewed if facts and circumstances indicate that it may
be impaired. If this review indicates that it is not recoverable, as determined
based on the estimated undiscounted cash flows of the entity acquired over the
remaining amortization period, the carrying amount of the goodwill is reduced
for the estimated shortfall of the cash flows discounted at the average cost of
capital for thrift institutions as compared to the carrying value.

INCOME TAXES

     The Bank files a consolidated federal income tax return and separate, or
combined, state income tax returns, depending on the state. Income taxes are
accounted for using the "asset and liability" method. Under this method, a
deferred tax asset or liability is determined based on the enacted tax rates
that will be in effect when the differences between the financial statement
carrying amounts and tax bases of existing assets and liabilities are expected
to be reported in the Bank's income tax returns. The effect on deferred taxes of
a change in tax rates is recognized in income in the period that includes the
enactment date of the change. A valuation allowance is provided for any deferred
tax asset for which it is more likely

than not that the asset will not be realized. Changes in valuation allowances
are recorded as a component of income.

PENSION COSTS

     The Bank's net periodic pension cost consists of the expected cost of
benefits earned by employees during the current period and an interest cost on
the projected benefit obligation, reduced by the expected earnings on assets
held by the retirement plan, amortization of transitional assets over a period
of 15 years (beginning in 1987), amortization of prior service cost and by
amortization of recognized actuarial gains and losses over the estimated future
service period of existing plan participants.

SEGMENT INFORMATION

     The Bank has determined that it has one reportable segment -- community
banking. The Bank offers a range of financial products and services to external
customers, including: accepting deposits from the general public; originating
residential, consumer and limited types of commercial loans (primarily loans
secured by multi-family properties); and marketing annuities and other insurance
products. Revenues for each of these products are disclosed in the consolidated
statements of income.

PENDING ACCOUNTING CHANGES

     Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities," and SFAS No. 137, "Accounting
for Derivative Instruments and Hedging Activities -- Deferral of the Effective
Date of SFAS No. 133," which delays the implementation date of SFAS No. 133 for
one year, to fiscal years beginning after June 15, 2000, provide a comprehensive
and consistent standard for the recognition of derivatives and hedging
activities. SFAS 133 requires all derivatives to be recorded on the balance
sheet at fair value. However, special accounting is provided for certain
derivatives that meet the definition of hedges. Changes in the fair value of
derivatives that do not meet the definition of hedges are required to be
reported in earnings in the period of change. The Bank does not use derivative
financial instruments such as futures, swaps, caps, floors, options or interest
or principal only strips of similar instruments. Therefore, SFAS No. 133 is not
expected to have a significant impact on the Bank. The Bank will implement this
statement on January 1, 2001.

2. BUSINESS COMBINATIONS

     On March 31, 1997, the Bank completed the acquisition of First Federal
Bancshares of Eau Claire, Inc. (First Federal) in a cash transaction for $125.1
million. The transaction has been accounted for as a purchase. First Federal was
the parent company of First Federal Bank of Eau Claire, F.S.B. First Federal had
total assets of $730.7 million as of March 31, 1997. This acquisition resulted
in the recording of identifiable intangibles (value of deposit base) of $10.4
million and goodwill (unidentifiable intangible asset) of $24.1 million. The
results of operations of the acquired company are included in the consolidated
financial statements from the date of acquisition.

     Scheduled amortization of intangibles was $2,711, $2,738 and $1,941 for the
years ended December 31, 1999, 1998 and 1997, and $469 (unaudited) and $1,355
(unaudited) for the six-month periods ended June 30, 2000 and 1999 respectively.
In 1999, increased competition for deposits from alternate investment products,
increases in interest rates which negatively impacted the volume of new loan
originations and credit standards more stringent than those used by the acquiree
caused management to

revise cash flow estimates to be realized from the acquired business.
Accordingly, $15,579 of intangibles were written off for the estimated shortfall
of the cash flows discounted at the average cost of capital for thrift
institutions as compared to the carrying value. This write-off is included in
amortization of intangibles on the statement of income. The unamortized balance
of goodwill and intangible assets was $11,027 (unaudited), $11,496 and $29,786
at June 30, 2000, and December 31, 1999 and 1998, respectively.

</TABLE>

     Advances that mature in the year 2004 consist of borrowings that are
redeemable at the option of the FHLB beginning at various times in 2001.

     The Bank is required to maintain unencumbered mortgage loans in its
portfolio aggregating at least 167% of the amount of outstanding advances from
the FHLB as collateral. The Bank's borrowings at the FHLB are limited to the
lesser of 35% of total assets or 60% of the book value of certain mortgage
loans. In addition, these notes are collateralized by FHLB stock of $14,585 at
June 30, 2000 (unaudited) and December 31, 1999.

10. EQUITY

     The Bank is subject to various regulatory capital requirements administered
by the federal banking agencies. Failure to meet minimum capital requirements
can initiate certain mandatory, and possible additional discretionary, actions
by regulators, that, if undertaken, could have a direct material effect on the
Bank's financial statements. Under capital adequacy guidelines and the
regulatory framework for prompt corrective action, the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities and certain off-balance-sheet items as calculated under regulatory
accounting practices. The Bank's capital amounts and classification are also
subject to qualitative judgments by the regulators about components, risk
weightings and other factors.

     As a state-chartered savings bank, the Bank is required to meet minimum
capital levels established by the State of Wisconsin in addition to federal
regulations.

     Quantitative measures established by federal regulation to ensure adequacy
require the Bank to maintain minimum amounts and ratios (set forth in the table
below) of total and Tier I capital (as these terms are defined in regulations)
to risk-weighted assets (as these terms are defined in regulations), and of Tier
I capital (as these terms are defined in regulations) to average assets (as
these terms are defined in regulations). For the state of Wisconsin, total
capital (as these terms are defined in regulations) as a ratio

of total assets must meet a minimum standard. Management believes, as of June
30, 2000 and December 31, 1999, that the Bank meets all capital adequacy
requirements to which it is subject.

     As of June 30, 2000 and December 31, 1999 and 1998, the most recent
notification from the State of Wisconsin categorized the Bank as well
capitalized under the regulatory framework for prompt corrective action. The
Bank is not aware of any conditions or events which would change their status as
well capitalized. There are no conditions or events since that notification that
management believes have changed the Bank's category.

11. EMPLOYEE BENEFIT PLANS

     The Bank has a discretionary, defined-contribution savings plan (the Plan).
The Plan is qualified under Sections 401 and 401(k) of the Internal Revenue Code
and provides employees meeting certain minimum age and service requirements the
ability to make contributions to the Plan on a pretax basis. The Bank may then
match a percentage of the employee's contributions. Matching contributions made
by the Bank were $39 (unaudited) and $36 (unaudited) in the six months ended
June 30, 2000 and 1999, $68 in 1999, $56 in 1998 and $52 in 1997.

     The Bank also has a defined-benefit pension plan covering employees meeting
certain minimum age and service requirements and a supplemental pension plan for
certain qualifying employees. The benefits are generally based on years of
service and the employee's compensation during the last five years of

     The supplemental pension plan had a projected benefit obligation of $3,110
and $3,247 and assets aggregating $2,777 and $2,521 at December 31, 1999 and
1998, respectively.

     Total net periodic pension expense was $513 (unaudited) and $438
(unaudited) in the six months ended June 30, 2000 and 1999, respectively.

     The Bank acquired an ESOP with the acquisition of First Federal which
covered substantially all former employees of First Federal with two or more
years of employment and who were at least 21 years of age. The cash proceeds
received by the ESOP in connection with the merger were used to prepay the
unpaid principal and interest outstanding under the ESOP. The remaining cash
balance has been invested in a mutual fund. An allocation was made to the
participants' accounts as of December 31, 1998 and the final allocation was made
as of December 31, 1999. The Bank is in the process of applying for a
determination letter to terminate the Plan and anticipates that all assets will
be available for distribution in a lump sum during 2000.

the bonds plus accrued interest on the outstanding principal at June 30, 2000
and December 31, 1999 and 1998, respectively. The Bank continues to receive
interest payments on the collateral.

     At June 30, 2000 (unaudited) and December 31, 1999 and 1998, United States
Treasury notes with outstanding principal balances aggregating approximately
$10,000 were held by the trustee as collateral for these bonds which had an
outstanding principal balance of $5,165 (unaudited), $5,165 and $5,410 for June
30, 2000 and December 31, 1999 and 1998, respectively. The third-party borrower
is not in default on any scheduled payments due under the bond issue which has a
scheduled maturity of on December 15, 2009.

14. FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK

     The Bank is party to financial instruments with off-balance-sheet risk in
the normal course of business to meet the financing needs of its customers.
These financial instruments consist of commitments to extend credit and involve,
to varying degrees, elements of credit and interest rate risk in excess of the
amount recognized in the consolidated statements of financial condition. The
contract amounts reflect the extent of involvement the Bank has in particular
classes of financial instruments and also represents the Bank's maximum exposure
to credit loss.

     Financial instruments whose contract amounts represent credit risk are as
follows:

     Commitments to extend credit are agreements to lend to a customer as long
as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and generally require payment of a fee. As some commitments expire without being
drawn upon, the total commitment amounts do not necessarily represent future
cash requirements. The Bank evaluates the collateral needed and creditworthiness
of each customer on a case by case basis. The

Bank generally extends credit only on a secured basis. Collateral obtained
varies, but consists principally of one-to four-family residences.

     Forward commitments to sell mortgage loans of $2,274 (unaudited), $0 and
$17,030 at June 30, 2000 and December 31, 1999 and 1998, respectively, represent
commitments obtained by the Bank from a secondary market agency to purchase
mortgages from the Bank and place them in a mortgage-backed security pool with a
defined yield. Commitments to sell loans expose the Bank to interest rate risk
if market rates of interest decrease during the commitment period. Commitments
to sell loans are made to mitigate interest rate risk on commitments to
originate loans and loans held for sale.

15. FAIR VALUE OF FINANCIAL INSTRUMENTS

     Disclosure of fair value information about certain financial instruments,
whether or not recognized in the consolidated financial statements, for which it
is practicable to estimate the value, is summarized below. In cases where quoted
market prices are not available, fair values are based on estimates using
present value or other valuation techniques.

     Those techniques are significantly affected by the assumptions used,
including the discount rate and estimates of future cash flows. In that regard,
the derived fair value estimates cannot be substantiated by comparison to
independent markets and, in many cases, could not be realized in immediate
settlement of the instrument. Certain financial instruments and all nonfinancial
instruments are excluded from this disclosure. Accordingly, the aggregate fair
value of amounts presented does not represent the underlying value of the Bank
and is not particularly relevant to predicting the Bank's future earnings or
cash flows.

     The following methods and assumptions are used by the Bank in estimating
its fair value disclosures of financial instruments:

     Cash and Cash Equivalents: The carrying amounts reported in the statements
of financial condition for cash and cash equivalents approximate those assets'
fair values.

     Investment and Mortgage-Related Securities: Fair values for these
securities are based on quoted market prices or such prices of comparable
instruments.

     Loans Receivable and Loans Held-for-Sale: The fair value of one- to
four-family fixed rate mortgage loans was determined based on the current market
price for securities collateralized by similar loans. For variable rate one to
four-family mortgage, consumer and other loans that re-price frequently and with
no significant change in credit risk, carrying values approximate fair values.
The fair value for fixed rate commercial real estate, rental property mortgage,
consumer and other loans was estimated by projecting cash flows at market
interest rates.

     Federal Home Loan Bank Stock: Federal Home Loan Bank stock is carried at
cost, which is its redeemable (fair) value, since the market for this stock is
restricted.

     Accrued Interest Receivable: The carrying value of accrued interest
receivable approximates fair value.

     Deposits and Advance Payments by Borrowers for Taxes and Insurance: The
fair values disclosed for variable rate investment accounts, NOW accounts,
passbook accounts, money market certificates, accrued interest and advance
payments by borrowers for taxes and insurance are equal to the carrying amounts
at the reporting date. Fair values for fixed-rate certificates of deposit are
estimated using a discounted cash

flow calculation that applies interest rates currently offered on certificates
to a schedule of aggregated expected monthly maturities on time deposits.

     Borrowings: The fair value of long-term borrowings is estimated using
discounted cash flow calculations with the discount rates equal to interest
rates currently being offered for borrowings with similar terms and maturities.

     Commitments to Extend Credit and Forward Commitments to Sell Loans: The
fair value of these commitments is considered to approximate the carrying values
due to the short-term nature of these commitments.

16. MERGER AND CONVERSION

     On February 21, 2000, Mutual and First Northern Capital Corp. (First
Northern), entered into an Agreement and Plan of Merger (the Merger Agreement).
The Merger Agreement has been approved by the boards of directors of Mutual and
First Northern.

     To accomplish the transaction Mutual also adopted a plan of restructuring
in which it 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, a mid-tier stock holding
company (Mid-Tier HC). The balance of the shares of 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 reorganization and merger, First Northern Capital
Corp will merge with and into Mid-Tier HC and, Mutual Savings Bank and First
Northern Savings Bank, S.A., will become wholly owned subsidiaries of Mid-Tier
HC.

     Subject to the terms and conditions of the Merger Agreement, at the time of
the Merger, each outstanding share of First Northern common stock (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 Mid-Tier HC Common Stock or a combination of cash and shares of
Mid-Tier HC Common Stock (Merger Consideration). Prior to the closing date,
Mutual will select the percentage of the total Merger Consideration to be paid
in Common Stock, which may not be less than 40% or more than 70%; the balance
will be paid in cash. 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. The Restructuring will be accounted for as a pooling of
interests, whereas the merger will be accounted for as a purchase.

     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 as
to both the Restructuring and the Merger. The depositors of Mutual must also
approve Mutual's Plan of 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 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 with the Securities and Exchange Commission.

     The amount and pricing of the proposed stock offering will be based upon an
independent appraisal of the Bank. In connection with the conversion, the costs
of issuing the common stock will be deducted from the sale proceeds. At June 30,
2000 and December 31, 1999, $749,000 (unaudited) and $0 of costs related to the
conversion have been capitalized. In the event that the consummation of the
conversion or merger do not occur, any recorded costs will be expensed.

     At the time of conversion, the Bank will establish a liquidation account in
an amount equal to its net worth as of the date of the latest consolidated
statement of financial condition appearing in the final prospectus. The
liquidation account will be maintained for the benefit of eligible account
holders and supplemental eligible account holders, if any, who continue to
maintain their deposit accounts at the Bank after the conversion.

     The liquidation account will be reduced annually to the extent that
eligible account holders and supplemental eligible account holders, if any, have
reduced their qualifying deposits as of each anniversary date. Subsequent
increases will not restore an eligible account holder's or a supplemental
eligible account holder's interest in the liquidation account. In the event of a
complete liquidation, each eligible account holder and supplemental eligible
account holder, if any, will be entitled to receive balances for accounts then
held.

     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 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.

                          INDEPENDENT AUDITOR'S REPORT

Board of Directors and Stockholders
First Northern Capital Corp.
Green Bay, Wisconsin

     We have audited the accompanying consolidated statement of financial
condition of First Northern Capital Corp. and Subsidiaries as of December 31,
1999, and the related consolidated statements of income, stockholders' equity,
and cash flows for the year then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audit. The consolidated
financial statements of First Northern Capital Corp. and Subsidiaries as of and
for each of the two years in the period ended December 31, 1998, were audited by
other auditors whose report dated January 22, 1999, expressed an unqualified
opinion on those statements.

     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

     In our opinion, the 1999 consolidated financial statements referred to
above present fairly, in all material respects, the financial position of First
Northern Capital Corp. and Subsidiaries at December 31, 1999, and the results of
their operations and their cash flows for the year then ended in conformity with
generally accepted accounting principles.

                 FIRST NORTHERN CAPITAL CORP. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The accounting and reporting policies of First Northern Capital Corp. and
Subsidiaries (the "Company") conform to generally accepted accounting principles
and general practices within the financial institution industry. Significant
accounting and reporting policies are summarized below.

     Business -- The Company provides a full range of financial services to
individual and corporate customers in Northeastern Wisconsin through First
Northern Savings Bank (the "Savings Bank"). The Company is subject to
competition from other traditional and nontraditional financial institutions and
is also subject to the regulations of certain federal and state agencies and
undergoes periodic examinations by those regulatory authorities.

     Principles of Consolidation -- The accompanying consolidated financial
statements include the accounts of First Northern Capital Corp., its wholly
owned subsidiary, First Northern Savings Bank, and the Savings Bank's wholly
owned subsidiaries, First Northern Investment, Inc. and Great Northern Financial
Services Corporation. All significant intercompany balances and transactions
have been eliminated. Investment in the Savings Bank's 50% owned subsidiary
Savings Financial Corporation, which is not material, is accounted for on the
equity method.

     Use of Estimates in Preparation of Financial Statements -- The preparation
of the accompanying consolidated financial statements of First Northern Capital
Corp. and Subsidiaries in conformity with generally accepted accounting
principles requires management to make estimates and assumptions that directly
affect the reported amounts of assets and liabilities at the date of the
financial statements and the reported amounts of revenue and expenses during the
reporting period. Actual results may differ from these estimates.

     Cash and Cash Equivalents -- The Company considers its interest-earning
deposits, which have a maturity of three months or less when purchased, to be
cash equivalents.

     Investment and Mortgage-Related Securities -- Management determines the
appropriate classification of securities at the time of purchase. Securities are
classified as held-to-maturity when the Company has the positive intent and
ability to hold the securities to maturity. Held-to-maturity securities are
stated at amortized cost. Securities not classified as held-to-maturity are
classified as available-for-sale. Available-for-sale securities are stated at
fair value with the unrealized gains and losses, net of tax, reported as
accumulated other comprehensive income (loss) within stockholders' equity until
realized. Interest and dividends are included in interest income from securities
as earned. Realized gains and losses and declines in value judged to be other
than temporary are included in net gains and losses from sales of investment and
mortgage-related securities. The cost of securities sold is based on the
specific-identification method.

     Fair values of many securities are estimates based on financial methods or
prices paid for similar securities. It is possible interest rates could change
considerably resulting in a material change in the estimated fair value.

     Federal Home Loan Bank Stock -- The Company's investment in Federal Home
Loan Bank (FHLB) stock is carried at cost which is its redeemable (fair) value
since the market for this stock is restricted.

     Loans Held-for-Sale -- Loans held-for-sale consist of the current
origination of certain fixed-rate mortgage loans and education loans which are
recorded at the lower of aggregate cost or fair value. Fees received from the
borrower and certain direct loan-origination costs are deferred and recorded as
an adjustment of the sale price. A gain or loss is recognized at the time of the
sale reflecting the present value of the difference between the contractual
interest rate of the loans sold and the yield to the investor, adjusted for the
initial value of mortgage servicing rights.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -- (CONTINUED)
     Loans Receivable and Related Interest Income -- Interest on loans is
accrued and credited to income as earned. Accrual of interest is generally
discontinued either when reasonable doubt exists as to the full, timely
collection of interest or principal or when a loan becomes contractually past
due by 90 days or more with respect to interest or principal. At that time, any
accrued but uncollected interest is reversed and additional income is recorded
only to the extent that payments are received and the collection of principal is
reasonably assured. Loans are restored to accrual status when the obligation is
brought current, has performed in accordance with the contractual terms for a
reasonable period of time, and the ultimate collectibility of the total
contractual principal and interest is reasonably assured. The balance of
nonperforming loans was not material to the consolidated financial statements at
December 31, 1999 and 1998.

     Loan Fees and Related Costs -- Certain loan-origination fees, commitment
fees, and direct loan-origination costs are being deferred and net amounts
amortized as an adjustment of the related loan's yield. The Savings Bank is
amortizing these amounts into interest income, using the level-yield method,
over the contractual life of the related loan. Other loan-origination and
commitment fees not required to be recognized as a yield adjustment are included
in loan fees.

     Allowances for Loan Losses -- Allowances for loan losses are provided based
on past experience and prevailing market conditions. Management's evaluation of
loss considers various factors including, but not limited to, general economic
conditions, loan portfolio composition, and prior loss experience. This
evaluation is inherently subjective since it requires material estimates that
may be susceptible to significant change. Loans are charged against the
allowance for loan losses when management believes the collectibility of the
principal is unlikely. In addition, various regulatory agencies periodically
review the allowance for loan losses. These agencies may require additions to
the allowance for loan losses based on their judgments of collectibility.

     The Company considers loans secured by one- to four-unit residential
properties and all consumer loans to be large groups of smaller-balance
homogenous loans. These loans are collectively evaluated in the analysis of the
adequacy of the allowance for loan losses.

     The Company's commercial and five or more family residential portfolio is
subject to a loan-by-loan analysis of the adequacy of the allowance for loan
losses and impairment. These loans are considered impaired when, based on
current information, it is probable the Company will not collect all amounts due
in accordance with the contractual terms of the loan agreement. The value of
impaired loans is based on discounted cash flows of expected future payments
using the loan's internal effective interest rate or the fair value of the
collateral if the loan is collateral dependent. The Company would establish an
allowance where the carrying amount of the impaired loan is greater than the
value. The Company did not have any impaired loans during 1999, 1998, or 1997.

     In management's judgment, the allowance for loan losses is adequate to
cover probable losses relating to specifically identified loans, as well as
probable losses inherent in the balance of the loan portfolio.

     Mortgage Servicing Rights -- The Company recognizes mortgage servicing
rights on loans that are originated and subsequently sold or securitized and
servicing is retained. A portion of the cost of the loans is required to be
allocated to the servicing rights based on the relative fair values of the loans
and the servicing rights. The Company amortizes these mortgage servicing rights
over the period of estimated net servicing revenue. Impairment of mortgage
servicing rights is assessed based on the fair value of those rights. Fair
values are estimated using discounted cash flows based on a current market
interest rate.

     Office Properties and Equipment -- Office properties and equipment are
stated at cost. Maintenance and repair costs are charged to expense as incurred.
Gains or losses on disposition of office properties and equipment are reflected
in income or expense, respectively. Depreciation is computed on the
straight-line method and is based on the estimated useful lives of the assets.
The cost of leasehold improvements is amortized using the straight-line method
over the lesser of the term of the respective lease or estimated
                                      FN-9

economic life of the improvements. Estimated useful lives include periods up to
40 years for properties and up to 12 years for furniture and equipment.

     Life Insurance Policies -- Investments in life insurance policies owned by
the Company are carried at the amount that could be realized under the insurance
contract.

     Income Taxes -- The Company files one consolidated federal income tax
return. Federal income tax expense (credit) is allocated to each subsidiary
based on an intercompany tax sharing agreement. The subsidiaries file separate
state franchise tax returns as applicable.

     Deferred income taxes have been provided under the liability method.
Deferred tax assets and liabilities are determined based on the difference
between the financial statement and tax bases of assets and liabilities as
measured by the current enacted tax rates which will be in effect when these
differences are expected to reverse. Deferred tax expense (benefit) is the
result of changes in the deferred tax asset and liability.

     Advertising Costs -- Advertising costs are expensed as incurred.

     Comprehensive Income -- Comprehensive income consists of net income and
other comprehensive income. Other comprehensive income includes unrealized gains
and losses on securities available-for-sale, net of tax, which are recognized as
a separate component of equity, accumulated other comprehensive income.

     Reclassifications -- Certain reclassifications have been made to the 1998
and 1997 consolidated financial statements to conform to the 1999
classifications.

     Future Accounting Change -- In June 1998, the Financial Accounting
Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS)
No. 133, "Accounting for Derivative Instruments and Hedging Activities." This
statement establishes accounting and reporting standards for derivative
instruments and for hedging activities. This statement requires an entity to
recognize all derivatives as either assets or liabilities in the statement of
financial condition and measure those instruments at fair value. The accounting
for changes in the fair value of a derivative depends on the intended use of the
derivative and the resulting designation. This statement is effective for fiscal
years beginning after June 15, 2000, as amended by SFAS No. 137. The effect of
adoption of this statement on the consolidated financial statements of the
Company is dependent on the amount and nature of derivatives in place at the
time of adoption. Management does not anticipate the adoption of this statement
will have a material effect on the financial position or operating results of
the Company.

     The Company is required to maintain as collateral unencumbered one- to
four-family mortgage loans such that the outstanding balance of FHLB advances
does not exceed 60% of the book value of this collateral. The FHLB advances are
also collateralized by the FHLB stock owned by the Company. The variable rate
term FHLB advances at December 31, 1999, which are included above, total
$30,000,000 and are at interest rates tied to the one-month LIBOR index.

allowed to borrow these deposits from the FRB until they are called. The
interest rate is the federal funds rate less 25 basis points. U.S. Treasury
Securities with a face value greater than or equal to the amount borrowed are
pledged as a condition of borrowing TT&L deposits.

matches 50% of the first 4% of the amount of each employee's contribution. In
addition, each employee may contribute amounts in excess of 4%, up to the lesser
of 15% of compensation or federal tax limits, with no Company participation.
Total expense relating to this plan for 1999, 1998, and 1997 was $459,000,
$442,000, and $379,000, respectively.

     The Company has an unfunded deferred retirement plan for directors. All
members of the Company's Board of Directors are eligible under the plan.
Directors of predecessor institutions who are members of an advisory board are
eligible at the discretion of the Company. Currently, there are four advisory
board members in the plan. The Company also has supplemental retirement plans
for several of its executives. Total expense relating to these plans for 1999,
1998, and 1997 was $360,000, $809,000, and $513,000, respectively. The Company
does not, as a policy, offer postretirement benefits other than the plans
discussed above.

     The Company has stock option plans which provide for the grant of incentive
stock options, nonqualified stock options, stock appreciation rights (SARs), or
restricted stock. The plans provide that incentive stock option prices will not
be less than the fair market value of the stock at the grant date and
nonqualified stock option prices shall not be less than 90% of the fair value of
the stock at the grant date. Options granted are eligible to be exercised
equally over a three-year period. All options expire no later than ten years
from the grant date.

     The fair value of each option granted is estimated on the grant date using
the Black-Scholes methodology. The following assumptions were made in estimating
fair value for options granted for the years ended December 31:

Dividend yield..............................................    3.00%          3.00%          4.50%
Risk-free interest rate.....................................    6.86%          5.41%          5.75%
Weighted average expected life (years)......................     7.0            7.0            7.0
Expected volatility.........................................    23.9%          22.2%          20.2%
</TABLE>

     The weighted average fair value of options granted as of their grant date,
using the assumptions shown above, was computed at $3.49, $3.11, and $1.45 per
share for options granted in 1999, 1998, and 1997, respectively.

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee and directors' stock options have
characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its employee
and directors' stock options.

     No compensation cost has been recognized for the plan. Had compensation
cost been determined on the basis of fair value, net income and earnings per
share would have been reduced as follows:

NOTE 10. STOCKHOLDERS' EQUITY

     The Board of Directors of the Company is authorized to issue cumulative
preferred stock in series and to establish the relative rights and preferences
of each series with respect to rates, redemption rights and prices, conversion
terms, voluntary liquidation rights, and voting powers. Cumulative preferred
stock will rank prior to common stock as to dividend rights and liquidation
preferences. Under Wisconsin state law, preferred stockholders are entitled to
vote as a separate class or series in certain circumstances, including any
amendment which would adversely change the specific terms of such series of
stock or which would create or enlarge any class or series ranking prior thereto
in rights and preferences (excluding substituting the surviving entity in a
merger or consolidation of the Company).

     The Savings Bank is subject to various regulatory capital requirements
administered by the federal and state banking agencies. Failure to meet minimum
capital requirements can initiate certain mandatory--and possibly additional
discretionary--actions by regulators that, if undertaken, could have a direct
material effect on the Savings Bank's financial statements. Under capital
adequacy guidelines and the regulatory framework for prompt corrective action,
the Savings Bank must meet specific capital guidelines that involve quantitative
measures of the Savings Bank's assets, liabilities, and certain off-
balance-sheet items as calculated under regulatory accounting practices. The
Savings Bank's capital

amounts and classification are also subject to qualitative judgments by the
regulators about components, risk weightings, and other factors.

     Quantitative measures established by federal and state regulation to ensure
capital adequacy require the Savings Bank to maintain minimum amounts and ratios
(set forth in the table below) of total and Tier I capital to risk-weighted
assets and of Tier I capital to average assets. Management believes, as of
December 31, 1999, that the Savings Bank meets all capital adequacy requirements
to which it is subject.

     As of December 31, 1999, the most recent notification from the Office of
Thrift Supervision (OTS) categorized the Savings Bank as well capitalized under
the regulatory framework for prompt corrective action. To be categorized as well
capitalized, the Savings Bank must maintain minimum total risk-based, Tier I
risk-based, and Tier I leverage ratios as set forth in the table. There are no
conditions or events since that notification that management believes have
changed the Savings Bank's category.

     The Savings Bank's actual and regulatory capital amounts (in thousands) and
ratios are as follows:

     The capital distribution regulations allow a well-capitalized bank to make
capital distributions during a calendar year up to 100% of its net income to
date plus the amount that would reduce by one half its surplus capital ratio at
the beginning of the calendar year. Any distributions in excess of that amount
requires prior OTS notice, with the opportunity for OTS to object to the
distribution.

     Unlike the Savings Bank, the Company is not subject to these regulatory
capital requirements or restrictions on the payment of dividends to it
stockholders. However, the source of its future dividends may depend upon
dividends from the Savings Bank.

     On October 18, 1996, the Company began a second stock repurchase program
for its common stock to be used for the exercise of stock options. The program
concluded on October 20, 1997, with a total of 60,800 shares being purchased at
an average price of $8.62 per share. A third stock repurchase program began
March 20, 1998, for up to 446,101 shares. The program concluded on December 31,
1999, with a total of 446,101 shares being repurchased at an average price of
$11.81 per share.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 13. SEGMENT INFORMATION -- (CONTINUED)
     While the Company's chief decision-makers monitor the revenue streams of
various Company products and services, operations are managed and financial
performance is evaluated on a Company-wide basis. Accordingly, all of the
Company's financial institution operations are considered by management to be
aggregated in one reportable operating segment.

NOTE 14. COMMITMENTS

     The Company is party to financial instruments with off-balance-sheet risk
in the normal course of business to meet the financing needs of its customers.
These financial instruments consist of commitments to extend credit and forward
commitments to sell mortgage loans. These instruments involve, to varying
degrees, elements of credit and interest rate risk in excess of the amount
recognized in the statements of financial condition. The contract amounts
reflect the extent of involvement the Company has in the particular class of
financial instrument. The Company's maximum exposure to credit loss for
commitments to extend credit is represented by the contract amount of those
instruments. For forward commitments to sell loans, the contract amounts do not
represent exposure to credit loss.

     Off-balance-sheet financial instruments whose contract amounts represent
credit and/or interest rate risk at December 31 are as follows:

     1998)..................................................    $   178    $ 4,656
  Adjustable rate (6.50% to 7.75% in 1999 and 5.75% to 8.00%
     in 1998)...............................................      2,554      3,618

Unused credit card lines of credit..........................      6,606      4,577
</TABLE>

     Commitments to extend credit are agreements to lend to a customer as long
as there is no violation of any condition established in the contract.
Commitments generally have fixed expiration dates or other termination clauses
and generally require payment of a fee. As some commitments expire without being
drawn upon, the total commitment amounts do not necessarily represent future
cash requirements. The Company evaluates the creditworthiness of each customer
on a case-by-case basis. The Company generally extends credit only on a secured
basis. Collateral obtained varies, but consists primarily of one- to four-
family residences.

     Commitments to extend credit on a fixed-rate basis expose the Company to a
certain amount of interest rate risk if market rates of interest substantially
increase during the commitment period.

     Forward commitments to sell mortgage loans represent commitments obtained
by the Company from a secondary market agency to purchase mortgages from the
Company and place them in a mortgage-related security pool with a defined yield.
Commitments to sell loans expose the Company to interest rate risk if market
rates of interest decrease during the commitment period. Commitments to sell
loans are made to mitigate interest rate risk on the existing loan portfolio and
on commitments to extend credit.

     Letters of credit are conditional commitments issued by the Company to
guarantee the performance of a customer to a third party. Those guarantees are
primarily issued to support public and private borrowing arrangements. The
credit risk involved in issuing letters of credit is essentially the same as
that

NOTE 14. COMMITMENTS -- (CONTINUED)
involved in extending loans to customers. The commitments are structured to
allow for 100% collateralization on all standby letters of credit.

     The Company has no investments in nor is a party to transactions involving
derivative investments, except mortgage-related securities which represent
minimal risk to the Company.

NOTE 15. FAIR VALUE OF FINANCIAL INSTRUMENTS

     Fair value estimates, methods, and assumptions for the Company's financial
instruments are summarized below.

     Cash and Cash Equivalents -- The carrying values approximate the fair
values for these assets.

     Investment and Mortgage-Related Securities -- Fair values are based on
quoted market prices where available. If a quoted market price is not available,
fair value is estimated using quoted market prices for similar securities.

     Loans Receivable and Loans Held-for-Sale -- For certain homogeneous
categories of loans, such as fixed-rate residential mortgages, fair value is
estimated using the quoted market prices for securities backed by similar loans,
adjusted for differences in loan characteristics. The fair value of other types
of loans is estimated by discounting the future cash flows using the current
rates at which similar loans would be made to borrowers with similar credit
ratings.

     Accrued Interest Receivable and Payable -- The carrying amounts reported in
the consolidated statements of financial condition approximate their fair
values.

     Federal Home Loan Bank Stock -- Fair value for the Federal Home Loan Bank
stock is based on its redeemable (carrying) value, as a market for this stock is
restricted.

     Deposits -- The fair value of deposits with no stated maturity, such as
passbooks, negotiable order of withdrawal accounts, and variable rate insured
money market accounts, is the amount payable on demand on the reporting date.
The fair value of fixed-rate, fixed-maturity, certificate accounts is estimated
using discounted cash flows with discount rates at interest rates currently
offered for deposits of similar remaining maturities.

     Borrowings -- Rates currently available to the Company for debt with
similar terms and remaining maturities are used to estimate fair value of
existing debt. The fair value of borrowed funds due on demand is the amount
payable at the reporting date. The fair value of borrowed funds with fixed terms
is estimated using discounted cash flows with discount rates at interest rates
currently offered by lenders for similar remaining maturities.

     Off-Balance-Sheet Instruments -- The fair value of commitments is estimated
using the fees currently charged to enter into similar agreements, taking into
account the remaining terms of the agreements, the current interest rates, and
the present creditworthiness of the counterparties. Since this amount is
immaterial, no amounts for fair value are presented.

</TABLE>

     Limitations -- Fair value estimates are made at a specific point in time
based on relevant market information and information about the financial
instrument. These estimates do not reflect any premium or discount that could
result from offering for sale at one time the Company's entire holdings of a
particular instrument. Because no market exists for a significant portion of the
Company's financial instruments, fair value estimates are based on judgments
regarding future expected loss experience, current economic conditions, risk
characteristics of various financial instruments, and other factors. These
estimates are subjective in nature and involve uncertainties and matters that
could affect the estimates. Fair value estimates are based on existing on- and
off-balance-sheet financial instruments without attempting to estimate the value
of anticipated future business and the value of assets and liabilities that are
not considered financial instruments. Deposits with no stated maturities are
defined as having a fair value equivalent to the amount payable on demand. This
prohibits adjusting fair value derived from retaining those deposits for an
expected future period of time. This component, commonly referred to as a
deposit base intangible, is neither considered in the above amounts nor is it
recorded as an intangible asset on the statement of financial condition.
Significant assets and liabilities that are not considered financial assets and
liabilities include office properties and equipment. In addition, the tax
ramifications related to the realization of the unrealized gains and losses can
have a significant effect on fair value estimates and have not been considered

                 FIRST NORTHERN CAPITAL CORP. AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

NOTE 17. SUBSEQUENT EVENT

     On February 21, 2000, the Company entered into an Agreement and Plan of
Merger (the "Merger Agreement") with Mutual Savings Bank ("Mutual"), a
Wisconsin-chartered mutual savings bank and OV Corp. (the "Merger Corp."), a
wholly owned subsidiary of Mutual organized for the purpose of effecting the
transactions contemplated by the Merger Agreement. The Merger Corp. will be the
surviving corporation. The Merger Agreement provides for the acquisition of the
Company by Mutual through a merger of the Company with and into the Merger Corp.

     Subject to the terms and conditions of the Merger Agreement, at the time of
the merger, each outstanding share of the Company's common stock will be
converted into the right to receive cash in the amount of $15.00 or 1.5 shares
of common stock of the Merger Corp. or a combination of cash and shares of the
Merger Corp.

     In connection with the Merger, the Company and Mutual will engage in a
restructuring. As part of the restructuring, Mutual will form a mutual holding
company. The mutual holding company will own a majority of the Merger Corp.'s
common stock. The balance of the shares of the Merger Corp. will be offered for
sale to Mutual's depositors and issued to First Northern stockholders in the
Merger. As a result of the restructuring, the Savings Bank and Mutual will
become wholly owned subsidiaries of the Merger Corp.

     The Merger and subsequent restructuring are subject to approval by the
stockholders of the Company, depositors of Mutual, and various regulatory
agencies.

     Concurrent with the execution of the Merger Agreement, the parties entered
into a Stock Option Agreement by which the Company granted Mutual an irrevocable
option to purchase up to 1,708,675 shares of the Company's stock equal to 19.9%
of the number of shares of the Company's stock outstanding on February 21, 2000,
at an exercise price of $9.0375 per share. The option would become exercisable
under certain circumstances if the Company becomes the subject of a third party
proposal for a competing transaction.
