                                     SUMMARY

         To more fully understand the offering, you should read this entire
document carefully, including the consolidated financial statements and the
notes to the consolidated financial statements.

OUR RESTRUCTURING, STOCK OFFERING AND FIRST NORTHERN MERGER

         Mutual Savings Bank is restructuring into the mutual holding company
form of organization. As part of the restructuring, we formed Bank Mutual, a
stock holding company and Mutual Savings Bancorp, MHC, a mutual holding company,
which we call the MHC. Also as part of the transaction, Mutual Savings will
convert from a mutual to a stock savings bank. At the conclusion of the
restructuring, Bank Mutual will own all of the stock of Mutual Savings and, in
turn, will be partially owned by the MHC. Simultaneously with the restructuring,
we will complete two other transactions--a merger transaction and a stock
offering. As a result of the merger transaction, Bank Mutual will own First
Northern Savings, which will continue to operate under that name. In the stock
offering, Bank Mutual is hereby offering for sale to the public a substantial
portion of the shares of common stock not to be issued to the MHC in the
restructuring.

         In significant part, the restructuring is being undertaken to
accommodate the First Northern merger.

MUTUAL

         For convenient reference, when we use the term "Mutual" we refer
together to Mutual Savings, Bank Mutual and the MHC, and including First
Northern Savings after the First Northern merger.

         Mutual Savings Bank

         Mutual Savings is a community-oriented savings bank which emphasizes
traditional financial services to individuals and businesses within its market
areas. Our principal business is attracting retail deposits from the general
public and investing those deposits, together with funds generated from other
operations, in residential mortgage loans, consumer loans, multi-family and
commercial real estate loans, and commercial business loans. We also invest in
various mortgage-related securities and investment securities. We seek to
differentiate ourselves from our competitors by:

         -    creating financial security for our customers in ways that
              continually emphasize quality, high value and uncompromising
              integrity;
         -    providing our employees with an environment that encourages and
              recognizes professional development, creativity and ambition; and
         -    supporting our communities in activities that improve the quality
              of life for all of their residents.

         Mutual Savings has 50 branches located in Wisconsin, primarily in the
southern and northwestern parts of the state, and one office in eastern
Minnesota. It serves over 80,000 households. At March 31, 2000, it had assets of
$1.7 billion, deposits of $1.3 billion and equity of $163.9 million. By asset
size, it is


                                       -2-

<PAGE>   5



the largest mutual savings institution headquartered in Wisconsin, and one of
the largest mutual savings institutions in the country. Mutual Savings has grown
both through acquisitions and internal growth. Its most recent acquisition was
of the $730.7 million asset First Federal Bancshares of Eau Claire in March
1997.

         As part of this transaction, Mutual Savings is converting from a
Wisconsin-chartered mutual savings bank into a federal stock savings bank. When
we refer to Mutual Savings, we also include the federal savings bank after that
conversion.

         Bank Mutual Corporation

         Bank Mutual will become a holding company by owning all of the common
stock of Mutual Savings and of First Northern Savings after the restructuring.
Bank Mutual has not engaged in any business to date. The primary office of Bank
Mutual is located at 4949 West Brown Deer Road, Brown Deer, Wisconsin 53223.

         After the restructuring, the stock offering and the First Northern
merger, we expect Bank Mutual to be the fifth largest financial institution
headquartered in the state of Wisconsin, based on pro forma total assets of $2.6
billion at March 31, 2000.

         Mutual Savings Bancorp, MHC

         The MHC will own more than half of the outstanding common stock of Bank
Mutual after the restructuring. We do not expect that the MHC will engage in any
business activity other than owning a majority of the common stock of Bank
Mutual and managing dividends, if any, it receives from Bank Mutual. We expect
that the MHC initially will waive the receipt of dividends declared by Bank
Mutual.

FIRST NORTHERN

         First Northern Savings Bank, S.A. is a Wisconsin-chartered stock
savings and loan association, with 19 branches located in northeastern
Wisconsin. First Northern Capital Corp. wholly owns First Northern Savings. At
March 31, 2000, First Northern had assets of $866.1 million, deposits of $567.7
million and shareholders' equity of $77.4 million. The primary office of First
Northern is located at 201 North Monroe Avenue, Green Bay, Wisconsin 54305. In
this document, we use "First Northern" to refer to First Northern Capital Corp.
and "First Northern Savings" to refer to First Northern Savings Bank, S.A.

         As part of the transactions which Mutual contemplates, Bank Mutual will
acquire First Northern Capital Corp. simultaneously with completion of this
offering. Mutual Savings and First Northern have signed a merger agreement for
that acquisition. As part of this transaction, First Northern Savings will
convert into a federally-chartered savings bank; when we refer to First Northern
Savings, we also include the federal savings bank after that conversion. After
the transaction, First Northern Savings will be wholly-owned by Bank Mutual.

         Mutual Savings does not expect to complete the restructuring and stock
offering if it does not believe that it will be able to complete the First
Northern merger. Mutual also does not expect to complete the First Northern
merger if it does not believe that it will be able to complete the restructuring

                                       -3-

and stock offering. For further information about First Northern and the merger,
see "The Parties" and "Index to Financial Statements-First Northern Data."

OPERATING STRATEGY

         Mutual Savings' operating strategy is to succeed as a well-capitalized,
profitable community-oriented bank. We seek to accomplish this goal by

         -    maintaining a community orientation and providing quality customer
              service;
         -    expanding our market area;
         -    continuing our commitment to residential lending, while
              diversifying our portfolio;
         -    managing credit risk;
         -    promoting core deposit accounts;
         -    limiting exposure to interest rate risk; and
         -    controlling expenses.

         First Northern's operating strategy is similar to Mutual Savings'
strategy. Although the two banks initially will operate separately after the
restructuring, their business philosophies will continue to be complementary.

         The following are operating strategy highlights.

- - -        Customer Service - Products and Delivery Systems

         Mutual provides convenient, quality service to customers. We leverage
         our branch network by emphasizing a sales culture and providing
         training and software to help our staff identify products that will
         benefit their customers. We offer a variety of customer conveniences,
         such as ATMs, 24-hour telebanking and a telephone "call center" to
         address customer questions. We offer investment and insurance services
         in order to attract new customers and build on existing relationships.
         First Northern Savings offers similar customer services. Both banks
         expect to establish internet banking services for retail and business
         customers.

- - -        Statewide Franchise

         Our business plan includes building a state-wide banking organization.
         To that end, we acquired First Federal Savings of Eau Claire in 1997,
         which gained us access to favorable markets in western Wisconsin. With
         the addition of First Northern, Bank Mutual will have $2.6 billion in
         assets and a substantial presence in prosperous, growing northeastern
         Wisconsin markets.

- - -        Lending Portfolio

         Historically, Mutual Savings has concentrated on residential lending.
         At March 31, 2000, 66.86% of our loan portfolio consisted of
         one-to-four family residential mortgage loans. Consumer loans,
         consisting primarily of home equity loans and lines of credit,
         comprised 17.68% of the portfolio. The remainder of the portfolio
         included multi-family, construction and commercial real estate mortgage
         loans, and commercial business loans. At March 31, 2000,
         one-to-four-family residential mortgage loans comprised 60.70% of First
         Northern's portfolio, while consumer loans accounted for 25.62% of the
         portfolio.

- - -        Portfolio Diversification and Business Banking

         Though residential loans pose less credit risk than other types of
         loans, we have increased our emphasis on non-residential lending in
         order to expand business opportunities and achieve the higher yields
         and shorter terms of such loans. Consumer loans comprised 9.72% of
         Mutual Savings' loan portfolio at December 31, 1995 and had grown to
         17.68% of the portfolio at March 31, 2000. In 1999, we hired
         experienced business bankers to expand our commercial business lending
         and related services, such as deposit products. We enhanced our
         commercial real estate capabilities by hiring additional experienced
         lenders.

         First Northern has also been expanding its consumer loan portfolio and,
         in recent years, established a niche in indirect auto lending. Auto
         loans comprised almost 50% of its consumer loans at March 31, 2000. In
         1999, First Northern Savings commenced commercial business lending. We
         believe that the attractive branch systems of both banks will
         facilitate continued expansion of consumer, commercial real estate and
         commercial business lending, while continuing to support a strong
         residential lending presence.

- - -        Asset Quality

         Though we have diversified the loan portfolio, we remain committed to
         conservative loan underwriting and credit review. Additionally, our
         investments are comprised of highly-rated securities. As a result of
         these practices and a stable economy, at March 31, 2000, our ratio of
         non-performing assets to total assets was 0.37%, and our ratio of
         allowance for losses to non-performing assets was 109.0%. These ratios
         are favorable compared to most savings institutions. At March 31, 2000,
         First Northern reported a ratio of non-performing assets to total
         assets of 0.08% and a ratio of allowance for losses to non-performing
         assets of 610.8%.

<PAGE>   8



- - -        Core Deposits

         We promote core deposits, such as savings and checking accounts,
         because they are generally a lower cost and more stable source of funds
         than time deposits. Additionally, unlike time deposits, they generate
         fee income. Over the past several years, we steadily increased our
         percentage of core deposits, which at March 31, 2000, accounted for
         39.3% of Mutual's deposits. At that date, 37.3% of First Northern's
         deposits were core deposits.

- - -        Interest Rate Risk

         We seek a balance between maximizing yield and limiting interest rate
         risk, which is the risk that earnings will be reduced if market
         interest rates fluctuate. Financial institutions face such risk because
         liabilities generally have shorter terms to repricing than loans. To
         limit this risk, we sell most long-term fixed rate loans that we
         originate, while keeping in our portfolio the shorter term and
         adjustable-rate loans. Additionally, we invest in adjustable-rate and
         short-term securities. First Northern follows a similar policy.

- - -        Cost Control

         Controlling overhead expense is important to profitability. One of our
         goals is to maintain a reasonable efficiency ratio, which is calculated
         as net interest expense (excluding amortization of intangible assets)
         to the sum of net interest income plus non-interest income. This ratio
         was an annualized 61.37% at March 31, 2000. For First Northern, this
         ratio was 59.45%.

- - -        Capital Strength

         By following the above business practices, Mutual Savings is
         financially strong. Our equity to assets ratio was 9.41% at March 31,
         2000. At that date, First Northern's ratio was 8.94%.

- - -        Profitable Core Operations

         Our core earnings primarily consists of net interest income, operating
         expenses and non-interest income. Our business practices have resulted
         in Mutual achieving increasing core earnings over the last several
         years. In 1999, we recorded a charge, unrelated to core operations,
         which reduced our results by $13.6 million. The charge was a special
         write-off of impaired intangible assets related to the acquisition of
         First Federal. Excluding the amortization of intangible assets, Mutual
         Savings' return on average assets for 1999 was 0.63%. Mutual's
         annualized return on assets, excluding amortization of intangible
         assets, was 0.75% at March 31, 2000. For First Northern, these returns
         were 0.96% and 0.78%, respectively.

THE FIRST NORTHERN MERGER

         Bank Mutual will acquire First Northern Savings in a merger
transaction. The consideration payable to First Northern shareholders will be
paid partly in cash and partly in Bank Mutual common stock. Before the merger
closes, Mutual will determine the relative proportion between cash and stock,
but the stock portion must be between 40% and 70% of the total consideration
paid. In this prospectus, we assume that 40% of the consideration will be Bank
Mutual stock; in that case, Bank Mutual will issue approximately 5,143,685
shares and pay approximately $77.2 million in cash. We also assume in all
calculations relating to the First Northern merger that the number of First
Northern shares outstanding is the number outstanding as of March 31, 2000.

         The Mutual Savings' board of directors believes that the First Northern
merger is attractive to Mutual for various reasons. From Mutual's perspective,
the First Northern merger would:

         -    combine two financial institutions of complementary business
              focuses.
         -    significantly expand Mutual's presence in northeastern Wisconsin,
              allowing it to enter attractive new markets through an established
              and attractive operation.
         -    permit Mutual to acquire this presence for fair consideration.
         -    allow elimination of certain duplicative costs and achievement of
              potential economies of scale over time by increasing size.
         -    complement the restructuring by providing a productive use for
              some of the offering's cash proceeds.
         -    obtain additional experienced and well-qualified employees.

         The merger will be accounted for as a purchase. Initially after the
restructuring, Bank Mutual expects to maintain First Northern Savings as a
subsidiary separate from Mutual Savings.

DESCRIPTION OF OUR STRUCTURE AFTER THE RESTRUCTURING

         The following chart shows our new structure, which is commonly referred
to as a mutual holding company structure with a mid-tier holding company, after
the restructuring, the offering and the First Northern merger:


                  The MHC                                Public Shareholders
                    50.1%                                          49.9%

                                         Bank Mutual

                  Mutual Savings                         First Northern Savings
                     100%                                           100%

PERSONS WHO CAN ORDER STOCK IN THE OFFERING

         Mutual is offering the shares of common stock of Bank Mutual in what we
call a "subscription offering." Subscription rights to purchase stock have been
granted to Mutual Savings' depositors in the order of priority listed below:


                                       -7-

<PAGE>   10



         (1)  Depositors with accounts at Mutual Savings with total balances of
              at least $50 on January 31, 1999;
         (2)  Our employee stock ownership plan;
         (3)  Depositors with accounts at Mutual Savings with total balances of
              at least $50 on June 30, 2000;
         (4)  Any depositors of Mutual Savings on            , 2000, the voting
              record date, who do not qualify in earlier priorities; and
         (5)  Directors, officers and employees of Mutual Savings who do not
              qualify in earlier priorities.

         Also, under the First Northern merger agreement and our plan of
restructuring, shares of Bank Mutual common stock will be issued to First
Northern shareholders so that at least 40% of the consideration in the merger is
in the form of Bank Mutual common stock. Therefore, at least 5,143,685 shares
will be issued in the merger separately from shares offered in the stock
offering. However, if shares of Bank Mutual common stock are available after all
orders have been filled in the subscription offering, Bank Mutual may issue any
amount of such available shares to former First Northern shareholders, in lieu
of cash. Under no circumstances, however, will more than 70% of the
consideration in the First Northern merger be paid in shares of common stock.

         The shares of Bank Mutual common stock not purchased in the
subscription offering or issued in the First Northern merger may be offered in
what we call a "community offering" in the following order of priority:

         (1)  "Residents" of the counties in which Mutual Savings or First
              Northern Savings maintain an office; and
         (2)  Other members of the public to whom we deliver a prospectus.

         The community offering, should it occur, will take place at the end of
the subscription offering or, at the discretion of Bank Mutual, concurrently
with or during the subscription offering.

TERMS OF THE OFFERING

         We are offering for sale between 4,633,564 and 7,178,464 shares of
common stock of Bank Mutual. The number of shares we issue may increase to up to
8,641,781 shares as a result of regulatory considerations or changes in
financial markets. If we increase the number of shares we issue, you will not
have the opportunity to change or cancel your stock order. The offering price is
$10.00 per share. Ryan, Beck & Co., Inc. will use its best efforts to assist us
in selling our stock. Ryan, Beck is not obligated to take or purchase any shares
of common stock in the offering. See "The Restructuring and the Offering the
Offering."

HOW WE DETERMINED THE OFFERING RANGE AND THE $10.00 PRICE PER SHARE

         The offering range is based on an independent appraisal of Mutual's pro
forma market value prepared by RP Financial, LC, an appraisal firm experienced
in appraisals of savings institutions.



                                       -8-

<PAGE>   11



         RP Financial has estimated that in its opinion as of June 12, 2000, the
estimated pro forma market value of Mutual, assuming completion of the stock
offering and the First Northern merger, was between $144.5 million and $195.5
million, with a midpoint of $170.0 million.

         The board of directors of Mutual Savings has determined to sell shares
in the stock offering at $10.00 share. Based on that price, assuming the
issuance of 5,143,685 shares to former shareholder of First Northern, the pro
forma market value of Mutual Savings ranged between $195.9 million and $246.9
million, with a midpoint pro forma market value of $221.4 million. This is the
"estimated valuation range." The stock issuance plan provides that total
outstanding shares must reflect the estimated valuation range and that public
ownership will equal 49.9 percent of outstanding shares, while the MHC's
ownership will equal 50.1 percent. Given the 5,143,685 shares to be issued to
the former shareholders of First Northern, this results in an offering range of
between 4,633,564 and 7,178,464 shares, with a midpoint of 5,906,014 shares.
Following the stock offering and First Northern merger, shares outstanding to
the public will therefore range between 9,777,249 and 12,322,149, with a
midpoint of 11,049,699 shares. Total outstanding shares, held by the MHC and
public owners, will range between 19,593,685 and 24,693,685.

         The appraisal was based in part upon Mutual Savings' financial
condition and operations, the financial condition and operations of First
Northern, the effect of the First Northern merger and the effect of the
additional capital Bank Mutual will raise from the sale of common stock. RP
Financial's independent appraisal will be updated before we complete our
restructuring.

         The $10.00 price per share was chosen by Mutual Savings' board of
directors because it is the price per share most commonly used in stock
offerings involving conversions and reorganizations of savings institutions.

LIMITS ON YOUR PURCHASE OF THE COMMON STOCK

         Your orders for common stock will be limited in the following ways:

         -    the minimum order is 25 shares;
         -    in each category of the offering, the maximum amount that an
              individual may purchase is $1,000,000;
         -    in all categories of the offering combined the total amount that
              an individual may purchase acting together with others is
              $1,000,000; and
         -    if we receive orders for a greater number of shares than we are
              offering, we will allocate the shares that we issue as described
              in "The Restructuring and The Offering--Limitations on Common
              Stock Purchases"; this may result in your receiving a smaller
              number of shares than you ordered.

We may increase or decrease either of the maximum purchase limitations at our
discretion. For additional information on these purchase limitations, see "The
Restructuring and The Offering--Limitations on Common Stock Purchases."

HOW YOU MAY PAY FOR YOUR SHARES

         In the subscription offering and the community offering, as shown on
the stock order form, you may pay for your shares by:

         -    personal check, bank check or money order; or
         -    authorizing us to withdraw money from certain types of deposit
              accounts that you maintain with Mutual Savings.

See "The Restructuring and The Offering -- Procedure for Purchasing Shares in
the Offerings" for additional information on how you may pay for your shares.

DEADLINE FOR ORDERS OF COMMON STOCK

         If you wish to purchase shares, you must submit a properly completed
stock order form, together with payment for the shares, to the Stock Information
Center as indicated on the enclosed Stock Order Form. You must submit your Stock

YOU MAY NOT SELL OR TRANSFER YOUR SUBSCRIPTION RIGHTS

         If you order stock in the subscription offering, you will be required
to state that you are purchasing the stock for yourself and that you have no
agreement or understanding to sell or transfer your rights. Federal law
prohibits you from selling or giving away your subscription rights. We intend to
take legal action against anyone who sells or gives away their subscription
rights. We will not accept your order if we have reason to believe that you sold
or transferred your subscription rights. If anyone offers to give you money to
buy stock in your name, in exchange for later transferring the stock, or if
someone requests to share in proceeds upon your future sale of Bank Mutual
stock, please inform our Stock Information Center at (800)         .

MARKET FOR THE COMMON STOCK

         We expect the common stock to trade on the Nasdaq National Market under
the symbol "BKMU." Ryan, Beck intends to make a market in the common stock but
it is under no obligation to do so.

HOW WE INTEND TO USE THE PROCEEDS WE RAISE FROM THE OFFERING

         Assuming we sell 5,906,014 shares in the offering and that we issue
5,143,683 shares to First Northern shareholders, we intend to use the net
proceeds from the offering as follows:

         -    $28.8 million will be used as part of the cash consideration to
              First Northern shareholders in the First Northern merger,
              reflecting that 60% of the consideration is paid in cash;



                                      -10-

<PAGE>   13



         -    $8.8 million will be loaned to the Mutual employee stock ownership
              plan to fund its purchase of common stock;


         -    $18.4 million will be retained by Bank Mutual.

         The amount of cash needed for the First Northern merger will vary
between 30% and 60% of the total merger consideration reflecting 40% of their
consideration. Assuming that 60% of the total consideration is paid in cash, the
total cash payment will be approximately $77.2 million. Mutual will obtain the
additional funds to pay the balance of the purchase price, together with the
costs of the merger and required cash-out of First Northern stock options, from
Mutual Savings' and First Northern Savings' existing capital and earnings.

         Bank Mutual may use some of the net proceeds of the offering as a
possible source of funds to pay dividends to shareholders, to repurchase common
stock, to finance the possible acquisition of other financial institutions and
other businesses that are related to banking, or for other general corporate
purposes.

OUR POLICY REGARDING DIVIDENDS

         We currently plan to pay an annual cash dividend of $0.28 per share,
payable quarterly at $0.07 per share starting for the first full quarter we are
a public company, but not earlier than the first quarter of 2001. We do not
guarantee that we will pay dividends, or that we will not reduce or eliminate
dividends in future periods. Regulations which apply to financial institutions
also may affect the dividends which Mutual can pay.

OUR DIRECTORS, OFFICERS AND EMPLOYEES WILL HAVE ADDITIONAL COMPENSATION AND
BENEFIT PROGRAMS AFTER THE RESTRUCTURING

         We are adding a new benefit plan for our officers and employees at no
cost to them, and will enter into new employment agreements.

         -    Employee Stock Ownership Plan. This plan will cover most of Mutual
              Savings' employees, and may be extended to First Northern Savings'
              and other Mutual employees. We will lend it money to buy up to 8%
              of the shares we sell in the offering and issue in the First
              Northern merger, combined. The ESOP will buy the shares either in
              the offering or in the open market. The plan will allocate the
              stock to employees over a ten-year period as additional
              compensation for their services.

         -    Employment Agreements. Mutual Savings has employment agreements
              with Michael T. Crowley, Sr. and Michael T. Crowley, Jr., which
              will continue after the restructuring. If Mutual discharges either
              of them without cause, or if either of them resigns because Mutual
              does not meet its obligations under these agreements, it must make
              a termination payment. Mutual is also entering into new employment
              agreements with four other executive officers. The new employment
              agreements will provide these officers with rights they do not
              currently have to receive severance benefits in the event of their
              actual or constructive discharge without cause.



                                      -11-

<PAGE>   14



         -    First Northern Employment Agreements. In connection with the First
              Northern merger, Mutual will assume the employment agreement of
              First Northern's chief executive officer and offer to replace
              existing employment agreements for the other executive officers of
              First Northern. These agreements will have provisions similar to
              those of the Mutual Savings employment agreements, except that Mr.
              Meeuwsen's agreement is for a period of five years and the others
              are for three years.

         We also plan to add the following stock-based benefit plans for our
directors, officers and employees in the near future:

         -    Stock Option Plan. Under this plan, Mutual may grant officers,
              directors and employees options to purchase Bank Mutual stock at a
              price that is set on the date we grant the option. The price that
              we set will not be less than our stock's current trading price
              when we grant the options, so the options will have realizable
              value only if our stock price increases. Recipients of options
              will have up to ten years to exercise their options. If we
              implement the stock option plan more than one year after
              restructuring, it may also include provisions allowing payment
              upon a change in control or retirement.

         -    Management Recognition Plan. This plan will allow selected Mutual
              officers, directors and employees to receive shares of our stock,
              without making any payment, if they work for us until the end of a
              specified service period or attain other performance goals. If we
              implement the management recognition plan more than one year after
              restructuring, it may also include provisions allowing payment
              upon a change in control or retirement.

Assuming we sell 5,906,014 shares in the offering and issue 5,143,685 shares in
the First Northern merger, we expect to ask our shareholders for approval to
grant options to purchase up to 1,104,970 of our shares and make stock grants
under a management recognition plan of up to 441,988 shares under the plans
described above. We will not implement a stock option plan or management
recognition plan unless shareholders approve them. We do not expect to ask Bank
Mutual shareholders to approve these plans until at least six months after we
complete the offering. We expect to obtain the shares we would need for these
plans in the stock offering and/or through stock repurchases on the open market
afterward.

         The following table presents the dollar value of the shares that Mutual
expects to grant under the employee stock ownership plan and the contemplated
management recognition plan and of those underlying options to be granted under
the stock option plan, and the percentage of Bank Mutual's outstanding common
stock that will be represented by these shares, all assuming the issuances
discussed above. Mutual based the value of the shares for the employee stock
ownership plan and management recognition plan on a price of $10.00 per share in
this offering.

         *We expect that options will be granted at then-current market prices.
         The fair value of the options will depend upon whether there is
         subsequent appreciation in Bank Mutual's stock price, the amount of
         that appreciation and other factors.

POSSIBLE CONVERSION OF THE MHC TO STOCK FORM

         In the future, the MHC may convert from mutual to capital stock form,
in a transaction commonly known as a "full conversion." If MHC were to undertake
a full conversion, we expect that Bank Mutual's public shareholders would own
the same percentage of the resulting entity as they owned prior to the full
conversion. Any full conversion would need to be conducted under laws and
regulations then in effect, which could affect what Bank Mutual shareholders
would actually receive. The board of directors has no current plan to undertake
a full conversion transaction, and we cannot assure that one will occur. For a
description of this possible full conversion, see "The Restructuring and The
Offering --Possible Conversion of the MHC to Stock Form."

                MUTUAL SAVINGS SELECTED FINANCIAL AND OTHER DATA

         In the following table, Mutual Savings provides selected financial data
for its past five fiscal years. Mutual Savings derived this information from its
audited financial statements, although the table itself is not audited. The
table also includes information at March 31, 2000 and for the three months ended
March 31, 2000 and 1999, derived from Mutual Savings' unaudited financial
statements. Operating results for the interim periods do not necessarily
indicate the results of Mutual Savings that you may expect for the entire year.
The following data should be read together with Mutual Savings' consolidated
financial statements and related notes and "Management's Discussion and
Analysis" which appear in this prospectus at pages F-1 and ____, respectively.

         We are presenting information for Mutual Savings rather than Bank
Mutual because Bank Mutual has not had any operations or material assets prior
to this time. In the restructuring, Bank Mutual will become the sole shareholder
of Mutual Savings immediately prior to the First Northern merger.

         In 1999, non-interest expense includes a special write-off of
intangible assets of $15.6 million which Mutual deemed to be impaired. The
intangible assets resulted from the 1997 acquisition of First Federal. The
effect on results for the year was a decrease of $13.6 million. See footnote 2
to Mutual Savings' consolidated financial statements. Also, in 1996,
non-interest expense includes a one-time FDIC Savings Association Insurance Fund
("SAIF") assessment of $6.4 million. All SAIF insured savings associations were
specially assessed in this quarter. The effect on net income of the assessment
in 1996 was a decrease of $3.9 million.

(a)      "Net interest rate spread" means the difference between the average
         yield on the average balance of interest-earning assets and the average
         balance of interest-bearing liabilities.
(b)      "Net interest margin" means the average cost of the net interest income
         divided by the average balance of interest-earning assets.
(c)      Computed using net interest income plus non-interest income as the
         denominator and non-interest expense (excluding amortization of
         intangible assets) as the numerator.

                FIRST NORTHERN SELECTED FINANCIAL AND OTHER DATA

         In the following table, we provide selected financial data for First
Northern for its past five fiscal years. First Northern derived this information
from its audited financial statements, although the table itself is not audited.
The table also includes information at and for First Northern's three months
ended March 31, 2000 and 1999, derived from First Northern's unaudited financial
statements. Operating results for the interim periods do not necessarily
indicate the results of First Northern that you may expect for the entire year.
The following data should be read together with First Northern's consolidated
financial statements and related notes and First Northern "Management's
Discussion and Analysis of Financial Condition and Results of Operations" which
appear beginning on page FN-1 of this prospectus.

         In 1996, non-interest expense includes a one-time SAIF assessment of
$2.9 million. The effect on net income of this assessment in 1996 was a decrease
of $1.7 million. Earnings per share in 1996 were decreased by $0.19.

                                  RISK FACTORS

         You should consider carefully the following risk factors before
deciding whether to invest in Bank Mutual's common stock.

CHANGING INTEREST RATES MAY HURT OUR PROFITS

         To be profitable, we have to earn more money in interest and fees than
we pay as interest and other expenses. Of our first mortgage loans maturing
after one year, a majority have interest rates that are fixed for the term of
the loan. While most of our deposit accounts consist of time deposit accounts
with remaining terms to maturity of less than one year, most of our loans have
longer remaining terms. If interest rates rise, which has been the case in
recent quarters, the amount of interest we pay on deposits is likely to increase
more quickly than the amount of interest we receive on our loans,
mortgage-related securities and investment securities. This would cause our
profits to decrease. Rising interest rates would likely reduce the value of our
mortgage-related securities and investment securities and may decrease demand
for loans and make it more difficult for borrowers to repay their loans. For
additional information on our exposure to interest rates, see "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Management of Interest Rate Risk."

INCREASES IN MARKET INTEREST RATES ARE LIKELY TO ADVERSELY AFFECT EQUITY

         As of March 31, 2000, we owned $520.6 million of securities available
for sale. Generally accepted accounting principles require that we carry these
securities at fair value on our balance sheet. Unrealized gains or losses on
these securities, reflecting the difference between the fair market value and
the amortized cost, is carried as a component of equity. In recent quarters,
rates have been rising. When market rates of interest increase, the fair value
of our securities available for sale generally decreases and equity decreases.
When rates decrease, fair value generally increases. As of March 31, 2000,
Mutual Savings' available for sale portfolio had an unrealized loss, because
fair value was $520.6 million and amortized cost was $534.7 million. At
March 31, 2000, First Northern Savings had an unrealized gain of $799,000 on
securities available for sale.

LOW DEMAND FOR REAL ESTATE LOANS MAY LOWER OUR PROFITABILITY

         Making loans secured by real estate is our primary business and primary
source of profits. If customer demand for real estate loans decreases, our
profits may decrease because our alternative investments, primarily securities,
earn less income for us than real estate loans. Customer demand for loans
secured by real estate could be reduced by a weaker economy, an increase in
unemployment, a decrease in real estate values or an increase in interest rates.

STRONG COMPETITION WITHIN OUR MARKET AREA MAY REDUCE OUR CUSTOMER BASE

         We encounter strong competition both in attracting deposits and
originating real estate and other loans. We compete with commercial banks,
savings institutions, mortgage banking firms, credit unions, finance companies,
mutual funds, insurance companies, and brokerage and investment banking firms.
Our market area includes branches of several commercial banks that are
substantially larger than us in terms of deposits and loans. In addition, tax
exempt credit unions operate in most of our market area and aggressively price
their products and services to a large part of the population. Our profitability
depends upon our continued ability to successfully increase our market share.

AFTER THE FIRST NORTHERN MERGER, WE WILL HAVE SIGNIFICANT INTANGIBLE ASSETS,
WHICH WILL HURT OUR FUTURE RESULTS

         In the First Northern merger, Bank Mutual will record approximately
$50.9 million in intangible assets. Bank Mutual will amortize these intangible
assets over 20 years. As a result, earnings will be reduced by approximately
$2.5 million annually. Also, at some point in the future, intangible assets may
become impaired, and we would need to write them off as a reduction to earnings.
For example, in 1999 Mutual Savings wrote off $15.6 million of "impaired"
intangible assets from the 1997 acquisition of First Federal. Even though this
special write-off did not affect our cash position, our 1999 results were hurt
by this action.

WE MAY EXPAND OUR LENDING ACTIVITIES IN RISKIER AREAS

         We have identified commercial real estate, commercial business and
consumer loans, including indirect auto loans, as areas for increased lending
emphasis. While increased lending diversification is expected to increase
interest income, non-residential loans carry greater risk of payment default
than residential real estate loans. As the volume of these loans increase,
credit risk increases. In the event of substantial borrower defaults, our
provision for loan losses would increase and therefore, earnings would be
reduced.

         First Northern's consumer loan portfolio includes $99.0 million of
indirect auto loans. Indirect auto lending is not a current business line for
Mutual Savings. Although First Northern has experienced minimal delinquencies in
its automobile loan portfolio, borrowers may be more likely to become delinquent
on an automobile loan than on a residential real estate loan. Moreover, unlike
the collateral for real estate loans, automobiles depreciate rapidly and, in the
event of default, principal loss as a percent of the loan balance depends upon
the mileage and condition of the vehicle at the time of repossession, over which
First Northern has no control.

IMPLEMENTING STOCK-BASED BENEFITS WILL INCREASE OUR FUTURE COMPENSATION EXPENSE
AND REDUCE OUR EARNINGS

         We intend to adopt a stock option plan which will provide for the
granting of options to purchase common stock, to adopt a management recognition
plan that will provide for awards of common stock to our eligible officers,
employees and directors and to have an employee stock ownership plan which may
purchase shares in the restructuring. In addition, we may adopt a restoration
plan that will supplement the benefits to select executive officers under the
employee stock ownership plan. These plans will increase our future costs of
compensating our directors and employees, reducing net earnings. The cost of
these plans will vary based on our stock price at specific points in the future.

THE MHC'S CONTROL OVER BANK MUTUAL MAY PREVENT TRANSACTIONS YOU WOULD LIKE

         The MHC will be managed by generally the same directors and officers
who manage Bank Mutual. Because the MHC will own a majority of Bank Mutual's
common stock after the restructuring, the board of directors of the MHC will
control the outcome of most matters put to a vote of shareholders of Bank
Mutual. We cannot assure you that the votes cast by the MHC will be in your best
interest as a shareholder. For more information regarding your lack of voting
control over Bank Mutual, see "Mutual Savings Bancorp, MHC" and "Restrictions on
Acquisition of Bank Mutual and Mutual Savings."

MUTUAL AND FIRST NORTHERN OPERATIONS MAY NOT INTEGRATE AS WE HOPE

         We anticipate that Mutual Savings and First Northern Savings will
initially operate as separate entities. That will delay or reduce any expense
reduction which the combined companies might achieve from a combination.
Similarly, any problems, such as may occur in systems conversions, which could
arise if we decide to combine the two operations will be deferred until such
time as the integration occurs. Similarly, Mutual and First Northern may


                                      -19-

<PAGE>   22



find after the merger that their operations and management philosophies will not
combine as well as they had expected, which could lead to operating
inefficiencies and complications going forward.

THIS TRANSACTION IS UNIQUE, WHICH MAY AFFECT MARKET ACCEPTANCE

         Mutual's restructuring to a mutual holding company format with a
mid-tier holding company, and the simultaneous acquisition of First Northern
Savings, is an unusual transaction. We are not aware of any prior transactions
in which this type of combination has occurred simultaneously with this type of
restructuring. In addition to regulatory requirements, we do not know whether
the unusual nature of the transaction, or ownership structure after the
transaction, will have an adverse effect on our operations or on the market for
Bank Mutual common stock.

         In particular, because many former First Northern shareholders may be
issued shares of Bank Mutual common stock in the First Northern merger, in order
to avoid a taxable transaction that would occur if they received cash, they may
be more likely to hold their Bank Mutual common stock than other types of
shareholders. Holding shares, versus selling them, could reduce market activity
for Bank Mutual common stock. Conversely, if the exchange ratio in the First
Northern merger requires some First Northern shareholders who would prefer to
receive cash to receive Bank Mutual shares, those shareholders may want to
quickly sell their Bank Mutual shares, which could create negative market
pressures and cause a drop in our share price.

THE PRICE TO BOOK RATIO OF THE COMMON STOCK IS HIGHER THAN IN MOST CONVERSION
TRANSACTIONS

         The offering price as a percentage of projected post-restructuring
tangible book value of the common stock sold as of March 31, 2000 ranges from
110.6% at the minimum of the offering range to 130.6% at the adjusted maximum of
the offering range. This price to pro forma tangible book value substantially
exceeds that of common stock sold both in:

         -    most mutual-to-stock conversions that do not involve the formation
              of a mutual holding company, that is, "full conversions"; and
         -    most recent offerings by companies that are reorganizing into the
              mutual holding company structure and are conducting a stock
              offering.

Prospective investors should be aware that the relatively high price to pro
forma tangible book value may have an unfavorable effect on the after-market
performance of the common stock during the period immediately following the
offering. See "Pro Forma Data."

RECENTLY, THE STOCK MARKET HAS BEEN VOLATILE AND MUTUAL-TO-STOCK CONVERSION
OFFERINGS HAVE NOT PERFORMED WELL IN THE AFTERMARKET

         Publicly traded stocks, including stocks of financial institutions,
have recently experienced substantial market price volatility. These market
fluctuations may be unrelated to the operating performance of the issuer. In
several cases, common stock issued by recently converted financial institutions
has traded at a price that is below the price at which such shares were sold in
the initial offerings of those companies. The purchase price of our common stock
sold in the offering is based on the independent appraisal by RP Financial. The
appraisal is not intended, and should not be construed, as a recommendation of
any kind as to the advisability of purchasing shares of common stock. The
valuation is based on estimates and projections of a number of matters, all of
which are subject to change from time to time. After our shares begin trading,
the trading price of our common stock will be determined by the marketplace, and
may be influenced by many factors, including prevailing interest rates, investor
perceptions of Bank Mutual, and general market for financial institution stocks
and economic conditions. Due to possible continued market volatility, we cannot
assure you that, following the stock offering, the trading price of our


                                      -20-

<PAGE>   23
common stock will be at or above the $10.00 per share price in this stock
offering. You should consider investing in our common stock only if you have a
long-term investment horizon.

                                   THE PARTIES

MUTUAL SAVINGS BANK

         Mutual Savings is a Wisconsin-chartered mutual savings bank, founded in
1892. Mutual Savings is the largest mutual savings bank in Wisconsin, and is one
of the largest in the country, based on asset size. Our deposits are insured by
the FDIC up to legal limits. We are examined and regulated by the Wisconsin
Department of Financial Institutions and the FDIC. However, as part of the
restructuring, Mutual Savings is converting into a federally chartered savings
bank. After our conversion to a federal charter, we will be examined and
regulated by the Office of Thrift Supervision. Mutual Savings' executive offices
are located at 4949 West Brown Deer Road, Brown Deer, Wisconsin 53223 and its
telephone number is (414) 354-1500.

         Serving over 80,000 households, Mutual Savings offers a full range of
savings, investment, checking and lending services. Our goal is to provide
continual high-quality service to our customers.

         For further information on our operations and financial condition, see
"Business of Mutual Savings Bank."

BANK MUTUAL CORPORATION

         Bank Mutual is a newly organized federally-chartered corporation. Bank
Mutual has not engaged in any business to date, except in connection with the
proposed restructuring and the First Northern merger. Upon completion of the
restructuring, Bank Mutual will serve as the holding company of Mutual Savings
and First Northern Savings. A majority of the outstanding shares of Bank
Mutual's common stock will be owned by the MHC. Bank Mutual's executive offices
are located at 4949 West Brown Deer Road, Milwaukee, Wisconsin 53223 and its
telephone number is (414) 354-1500.

         After the restructuring, the stock offering and the First Northern
merger, we expect Bank Mutual to be the fifth largest financial institution
headquartered in the state of Wisconsin, based on pro forma total assets of $2.6
billion at March 31, 2000.

MUTUAL SAVINGS BANCORP, MHC

         As part of our restructuring, Mutual Savings will organize Mutual
Savings Bancorp, MHC as a federally-chartered mutual savings bank holding
company which will be registered as a savings association holding company with
the OTS. Persons who had liquidation rights with respect to Mutual Savings as of
the date of the restructuring will continue to have liquidation rights solely
with respect to the MHC. Their liquidation rights in the


                                      -21-

<PAGE>   24



MHC will exist as long as they maintain a deposit account at Mutual Savings. The
MHC's executive offices are located at 4949 West Brown Deer Road, Milwaukee,
Wisconsin 53223 and its telephone number is (414) 354-1500.

         The MHC's principal assets will be the shares of common stock of Bank
Mutual it receives in the restructuring and approximately $100,000 it receives
as its initial capitalization. At the present time, we expect that the MHC will
not engage in any business activity other than its investment in a majority of
the common stock of Bank Mutual and the management of any cash dividends
received from Bank Mutual. Federal law and regulations require that as long as
the MHC is in existence it must own a majority of Bank Mutual's voting stock.
Federal law, regulations and the plan of restructuring would permit the MHC to
convert to the stock form of organization at some later time, but we have no
current plans for such a conversion. For additional information regarding a
stock conversion, see "The Restructuring and The Offering -- Possible Conversion
of the MHC to Stock Form."

FIRST NORTHERN SAVINGS; THE FIRST NORTHERN MERGER

         In a separate transaction which will occur at the same time as Mutual's
restructuring, Bank Mutual will acquire First Northern Capital Corp., which is
the holding company of First Northern Savings Bank, SA, in a merger transaction.
First Northern Savings is a Wisconsin-chartered savings and loan association
headquartered in Green Bay, Wisconsin. First Northern Savings has 19 offices in
northeastern Wisconsin. First Northern had $866.1 million in total assets and
$567.7 million in deposits at March 31, 2000. For further information about
First Northern, including financial statements and management's discussion and
analysis, see "Index to Financial Statements - First Northern Data".

         In the First Northern merger, each outstanding share of First Northern
common stock will be converted into either $15 in cash or 1.5 shares of Bank
Mutual common stock. The percent of shares converted into Bank Mutual common
stock will be between 40% and 70% of First Northern's outstanding shares; the
precise number will be chosen by Mutual. The balance of the shares will be
converted into cash. Assuming that, within that range, 40% of the shares of
First Northern common stock are to be converted into shares of Bank Mutual
common stock, approximately 5,143,685 shares of Bank Mutual common stock will be
issued to former First Northern shareholders and approximately $77.2 million
will be paid in cash for the balance of the shares. A portion of the cash will
be paid using net proceeds of the stock offering; the remainder will be paid
using available funds from Mutual Savings and First Northern Savings. See "Pro
Forma Data" and "How We Intend to Use Proceeds from this Offering."

         In significant part, the restructuring is being undertaken to
accommodate the First Northern merger. The First Northern merger will not
proceed if the restructuring does not occur. Mutual Savings' board of directors
believes that the First Northern merger is attractive to Mutual for various
reasons. From Mutual's perspective, the First Northern merger would:

         -        combine two financial institutions of complementary business
                  focuses.
         -        significantly expand Mutual's presence in northeastern
                  Wisconsin, allowing it to enter attractive new markets through
                  an established and attractive operation.
         -        permit Mutual to acquire this presence for fair consideration.
         -        allow elimination of certain duplicative costs and achievement
                  of potential economies of scale over time by increasing size.
         -        complement the restructuring by providing a productive use for
                  some of the offering's cash proceeds.
         -        obtain additional experienced and well-qualified employees.

         The First Northern merger remains subject to regulatory and First
Northern shareholder approval and other closing conditions. Mutual does not
intend to complete the restructuring and the related offering if it does not
expect the First Northern merger to occur substantially simultaneously.
Similarly, Mutual does not expect to


                                      -22-

<PAGE>   25
complete the First Northern merger unless the restructuring can be completed.
The First Northern merger will be a tax-free reorganization for Mutual and First
Northern.


               HOW WE INTEND TO USE THE PROCEEDS FROM THE OFFERING

         The net proceeds will depend on the total number of shares of common
stock we sell in the offering, which in turn will depend on RP Financial's
appraisal, regulatory and market considerations, and the expenses incurred in
connection with the offering. Although we will not be able to determine the
actual net proceeds from the sale of the common stock until we complete the
offering, we estimate the net proceeds to be between $43.4 million and $82.9
million.

         Bank Mutual intends to use the net proceeds from the offering as
follows:

- - --------------------
</TABLE>
(a)      The cash portion of the purchase price in the First Northern merger
         will exceed the proceeds of the stock offering. As a result it is
         anticipated that Mutual Savings and First Northern Savings will
         transfer funds to Bank Mutual sufficient to complete the transaction
         and provide working cash to Bank Mutual.

(b)      Assumes 40% of First Northern's shares are converted into Bank Mutual
         common stock. If the percentage is higher, the total number of shares
         sold in this offering will be lower, but correspondingly less cash will
         be used to fund the cash payments in the First Northern merger.

(c)      If the employee stock ownership plan buys shares in the market after
         the restructuring instead of in the offering, the purchase price of
         those shares may be less or more than the $10.00 per share offering
         price, which would vary the amount of proceeds used for this purpose.

         The net proceeds of the offering are not expected to be sufficient to
fund the entire cash consideration payable in the First Northern merger. The
amount of additional cash needed will depend upon the percent of First Northern
shares that are converted into cash. Mutual expects to obtain the additional
cash needed from Mutual Savings and First Northern Savings.

         The net proceeds may vary because total shares sold and total expenses
may be more or less than our estimates. For example:


                                      -23-
<PAGE>   26
         -        Our expenses would increase if a syndicated community offering
                  is used to sell shares not purchased in the subscription
                  offering and community offering.

         -        The net proceeds will vary if the offering range is adjusted
                  to reflect a change in the estimated pro forma market value of
                  Bank Mutual.

         -        Similarly, if greater than 40% of the consideration in the
                  First Northern merger is Bank Mutual common stock, a portion
                  of the offering shares will be provided to First Northern
                  shareholders rather than sold to subscribers and, therefore,
                  the net offering proceeds will be less; however, there will be
                  a corresponding reduction in the amount of proceeds needed for
                  cash payments to First Northern shareholders.

         -        Payments for shares made through withdrawals from existing
                  deposit accounts will not result in the receipt of new funds
                  for investment by Mutual, but will result in a reduction of
                  Mutual Savings' deposits and interest expense as funds are
                  withdrawn from subscribers' accounts.

         BANK MUTUAL MAY USE THE PROCEEDS IT RETAINS FROM THE OFFERING:

         -         to pay dividends to shareholders;
         -         to repurchase shares of common stock issued in the offering
                   and the First Northern merger;
         -         to finance the possible acquisition of financial institutions
                   or other businesses that are related to banking;
         -         to make equity or debt investments in Mutual Savings or First
                   Northern Savings;
         -         to invest in securities; and
         -         for general corporate purposes.


                       MUTUAL'S POLICY REGARDING DIVIDENDS

         Bank Mutual currently plans to pay shareholders a cash dividend at an
annual rate of $0.28 per share. The dividend would be declared and payable
quarterly at a rate of $0.07 per share, starting for the first full quarter we
are a public company, but not earlier than the first quarter of 2001. The
payment of dividends will be subject to the determination of our board of
directors, which will take into account, among other factors, our financial
condition, results of operations, tax considerations, industry standards,
economic conditions and regulatory restrictions that affect the payment of
dividends by Mutual Savings and First Northern Savings to Bank Mutual. Bank
Mutual must also comply with regulations that govern the level of dividends
which may pay as well as the regulatory capital requirements of Bank Mutual as a
savings bank holding company. We cannot guarantee that we will pay dividends or
that, if paid, that we will not reduce or eliminate dividends in the future.

         If Bank Mutual pays dividends to its shareholders, it will be required
to pay dividends to the MHC unless the MHC elects to waive dividends. We
currently anticipate that initially the MHC will waive dividends paid by Bank
Mutual. Any decision to waive dividends will be subject to regulatory approval.
If the OTS does not permit the dividend waiver, it is possible that Bank Mutual
would need to lower the amount of dividends in order to retain sufficient
capital at Bank Mutual. See "Regulation - MHC Regulation - Waiver of Dividends."

         As the principal assets of Bank Mutual, Mutual Savings and First
Northern Savings will provide the principal sources of funds for the payment of
dividends by Bank Mutual. Federal law provides that dividends may be paid by
Mutual Savings and First Northern Savings, as federal institutions, only out of
net income and unrestricted capital surplus. However, these subsidiaries will
not be permitted to pay dividends on their capital stock if, among other things,
their capital would be reduced below the amount required for the liquidation
account. See "The Restructuring and The Offering -- Effects of the Restructuring
- - -- Liquidation Rights."


                                      -24-

<PAGE>   27
         Any payment of dividends by Mutual Savings or First Northern to Bank
Mutual which would be deemed to be drawn out of their bad debt reserves would
require a payment of taxes at the then-current tax rate by them on the amount of
earnings deemed to be removed from bad debt reserves for such distribution.
Mutual Savings and First Northern do not intend to make any distribution to Bank
Mutual that would create this type of a tax liability. See "Taxation."

         Bank Mutual and Mutual Savings have also committed to the OTS in
connection with the reorganization, that during the one-year period following
the completion of the restructuring, Bank Mutual will not declare an
extraordinary dividend to shareholders which would be treated by recipient
shareholders as a tax-free return of capital for federal income tax purposes
without prior approval of the OTS.


                       MARKET FOR BANK MUTUAL COMMON STOCK

         Mutual has not previously issued common stock, so there is no market
for the common stock. We have received conditional approval to have our common
stock quoted on the Nasdaq National Market under the symbol "BKMU" after the
restructuring. Ryan, Beck has advised us that it intends to make a market in the
common stock following the restructuring, but is under no obligation to do so.
We will encourage and assist additional market makers to make a market in our
common stock.

         Making a market involves maintaining bid and asked quotations and being
able, as principal, to effect transactions in reasonable quantities at those
quoted prices. Various securities laws and other regulatory requirements apply
to these activities. Additionally, the development of a liquid public market
depends on the existence of willing buyers and sellers, the presence of which is
not within our control, or that of any market maker. The number of active buyers
and sellers of the common stock at any particular time may be limited. Under
such circumstances, you could have difficulty selling your shares on short
notice and you should not view the common stock as a short-term investment. We
cannot assure you that an active and liquid trading market for the common stock
will develop or that, if it develops, it will continue, nor can we assure you
that if you purchase shares you will be able to sell them at or above $10.00 per
share.

         In connection with Mutual's restructuring, Mutual has obtained an
appraisal from RP Financial which Mutual used in establishing a $10.00 per share
offering price. See "The Restructuring and the Offering -- Stock Pricing and
Number of Shares to be Issued." However, an appraisal is not a prediction of the
future market value of Bank Mutual shares.

                         REGULATORY CAPITAL COMPLIANCE

At March 31, 2000, Mutual Savings and First Northern Savings exceeded all
regulatory capital requirements. Set forth below is a summary of the capital
computed under generally accepted accounting principles and the compliance
with regulatory capital standards at March 31, 2000, on a historical and pro
forma basis. We have assumed that the indicated number of shares were sold as of
March 31, 2000 and shares were issued to First Northern shareholders in
conjunction with the merger agreement. We assumed that Mutual Savings received
none of the proceeds from the offering. We further assume that in conjunction
with the initial capitalization of Bank Mutual, that capital will be
transferred to Bank Mutual in the amounts of $44.0 million, $40.0 million, $36.3
million and $32.0 million from Mutual Savings and $10.5 million, $8.4 million,
$6.8 million and $4.5 million from First Northern Savings at the minimum,
midpoint, maximum and adjusted maximum, respectively, and that MHC is initially
capitalized by a transfer from Mutual Savings of $100,000 in all pro forma
cases. Finally, we assume that First Northern Savings' capital will be reduced
by $4.8 million of non-recurring merger-related expenses.

After the restructuring, the stock offering and the First Northern merger, we
believe that Mutual Savings and First Northern Savings will continue to exceed
all applicable regulatory capital requirements. For a discussion of the capital
requirements applicable to Mutual Savings, see "Regulation - Mutual Savings and
First Northern Savings Federal Regulation Following Restructuring".

</TABLE>



(a) Leverage capital levels are shown as a percentage of "average assets" and
    "risk-based capital" levels are calculated on the basis of a percentage of
    "risk-weighted assets", as each is defined in bank regulations.

(b) GAAP is defined as generally accepted accounting principles.

(c) The current leverage capital requirement for savings banks is 4%-5% of total
    adjusted assets. For savings banks that receive the highest supervisory
    ratings for safety and soundness and that are not experiencing or
    anticipating significant growth, the leverage capital requirement is 3%.

BANK MUTUAL CAPITALIZATION FOOTNOTES

(a)  As adjusted to give effect to an increase in the number of shares which
     could occur due to an increase in the offering range of up to 15% as a
     result of general regulatory considerations or changes in market or general
     financial and economic conditions following the commencement of the
     offering.
(b)  Does not reflect withdrawals from deposit accounts for the purchase of
     common stock in the offering. Withdrawals from deposit accounts would
     reduce pro forma deposits by the amount of such withdrawals.
(c)  Reflects the sale of the indicated number of shares plus shares issued to
     MHC equal to 50.1% of the total shares outstanding.
(d)  Reflects the issuance of 5,143,685 Bank Mutual shares to shareholders of
     First Northern at a value of $10.00 per share in accordance with the merger
     agreement, using the purchase method of accounting.
(e)  The retained earnings of Mutual Savings will be substantially restricted
     after the offering.
(f)  Reflects the reduction in retained earnings related to the initial
     capitalization of Ban k Mutual in the amount of $44.0 million, $40.0
     million, $36.3 million and $32.0 million at the minimum, midpoint, maximum
     and 15% above the maximum of the range, respectively.
(g)  Assumes the cancellation of First Northern's treasury shares at the time of
     the consummation of the merger..
(h)  Assumes that 8% of the shares sold in connection with the offering and
     issued to shareholders of First Northern will be purchased by the employee
     stock ownership plan and the funds used to acquire the employee stock
     ownership plan shares will be borrowed from Bank Mutual. The common stock
     acquired by the employee ownership plan is reflected as a reduction of
     shareholders' equity. If the employee stock ownership plan buys shares in
     the market after the reorganization, the purchase price of the those shares
     may be less or more that the $10.00 offering price.
(i)  Assumes that, subsequent to the offering, an amount equal to 4% of the
     shares of common stock issued in the offering is purchased by a management
     recognition plan through open market purchases. The proposed management
     recognition plan is intended to be adopted by Bank Mutual and presented for
     approval of shareholders at a meeting of shareholders to be held at least
     six months following completion of the offering. The common stock purchased
     by the management recognition plan is reflected as a reduction of
     shareholders' equity.

                            PRO FORMA FINANCIAL DATA

               PRO FORMA DATA REFLECTING THE FIRST NORTHERN MERGER

         In the following tables, we provide unaudited pro forma condensed
combined financial data of Bank Mutual and subsidiaries which includes the
historical data for Mutual Savings and First Northern plus adjustments to give
effect to the First Northern merger. The data are based on an assumption that
Bank Mutual common shares are issued for 40% of First Northern shares
outstanding on March 31, 2000 and cash is paid for 60% of First Northern shares
outstanding on March 31, 2000. Additional assumptions are discussed in the notes
that follow the table. Operating results data assumes that this transaction
occurred on the first day of each period shown, whereas financial condition data
assumes that this transaction occurred at the date indicated. The per share
information is calculated assuming the number of shares outstanding is unchanged
throughout each respective time period.

         In accordance with generally accepted accounting principles the First
Northern merger will be accounted for using the purchase method. Accordingly,
the recorded assets and liabilities of Mutual Savings will be carried forward at
their recorded amounts and the historical operating results of Mutual Savings
will be unchanged for the prior periods being reported on. However, the assets
and liabilities of First Northern will be adjusted to fair value at the date of
the merger. To the extent that the purchase price, consisting of the number of
shares of Bank Mutual to be issued to former First Northern shareholders at fair
value plus cash to be paid to former First Northern shareholders, exceeds the
fair value of the net assets of First Northern at the merger date, that excess
will be reported as an intangible asset to be amortized to the consolidated
income of Bank Mutual in future periods. Further, the purchase accounting method
results in the operating results of First Northern only being included in the
consolidated income of Bank Mutual beginning from the date of the merger.

         We present this pro forma data as an illustration only. It does not
necessarily indicate the financial position or financial results that would have
actually been reported if the restructuring and merger had occurred at the
beginning of the periods presented, nor do they necessarily indicate future
financial position or results of operations. The pro forma results of operations
neither assume nor incorporate any benefits from cost savings or synergies of
operations of the combined companies. The effects of the stock offering are
reflected in "Pro forma Data Reflecting the Stock Offering" below and the
following tables should be read in conjunction with that information.

PRO FORMA DATA REFLECTING THE STOCK OFFERING

         In the following tables, we provide unaudited pro forma condensed
financial data of, and assumptions relating to, Bank Mutual reflecting the stock
offering. The data assumes that the First Northern merger has also occurred;
detailed effects of the First Northern merger are reflected in the pro forma
data on the preceding pages.

         In accordance with generally accepted accounting principles, the
restructuring will be accounted for at historical cost in a manner similar to
pooling of interest accounting in accordance with generally accepted accounting
principles. Accordingly, the carrying value of Mutual Savings' assets,
liabilities and equity will not be affected by the restructuring and will be
reflected in the successor stock savings bank's financial statements based upon
their historical amounts.

BANK MUTUAL CORPORATION
PRO FORMA FOR STOCK OFFERING
MARCH 31, 2000


(a)  Assumes an increase in the number of shares due to a 15% increase in the
     maximum of the offering range to reflect changes in market and financial
     conditions before the conversion and stock offering is completed or to fill
     the order of the ESOP.
(b)  Estimated adjusted proceeds consist of the estimated net conversion
     proceeds, minus (i) the proceeds attributable to the purchase by Mutual
     Savings' ESOP and (ii) the value of the shares to
     be purchased by Mutual Savings' recognition plan after the conversion and
     stock offering, subject to shareholder approval, at an assumed purchase
     price of $10.00 per share. Marketing fees and other issuance expenses
     consist of legal, accounting, printing and other fixed costs totaling
     $2,345,000 plus variable marketing fees based on 1.50% of gross proceeds
     less shares to be acquired by the ESOP.
(c)  Reflects the combined historical net earnings and shareholders' equity of
     Mutual Savings and First Northern for the three months ended March 31,
     2000, adjusted for the merger.
(d)  Consists of interest earned on net proceeds from the sale of minority
     ownership of Bank Mutual at 6.26%, which represents the one year U. S.
     treasury note rate at March 31, 2000.
(e)  Bank Mutual assumes that 8% of the shares of common stock issued in the
     restructuring, stock offering and merger will be purchased by the ESOP
     (782,180, 883,976, 985,772, and 1,102,837 shares at the minimum, midpoint,
     maximum and adjusted maximum, respectively). Bank Mutual also assumes that
     the funds used to acquire such shares will be borrowed by the ESOP from
     Bank Mutual. Mutual Savings intends to make quarterly contributions to the
     ESOP over a ten-year period in an amount at least equal to the principle
     and interest requirements of the debt. The pro forma earnings assumes (i)
     that the loan to the ESOP is payable over ten years in equal installments
     of principle with the ESOP shares having an average fair value of $10.00
     per share; (ii) that the loan to the ESOP bears interest at the Mutual
     Savings' prime interest rate; (iii) that the ESOP expense for the period is
     equivalent to the principal payment for the period and are made throughout
     the period (the interest expense paid by the Mutual Savings and the
     interest income recognized by the Bank Mutual on the ESOP debt are
     eliminated in consolidation); (iv) that 19,555, 22,099, 24,644 and 27,571
     shares are committed to be released with respect to the quarter ended March
     31, 2000, at the minimum, midpoint, maximum and adjusted maximum,
     respectively; (v) only the ESOP shares committed to be released during the
     period are considered outstanding for the purposes of the earnings per
     share calculations based on the average shares to be released during the
     year; and (f) the effective tax rate is 40.0% for the period.
(f)  Bank Mutual assumes that 4% of the shares of common stock issued in the
     conversion, stock offering and merger will be purchased by the recognition
     plan

                                      -37-

     (391,090, 441,988, 492,886, and 551,419 shares at the minimum,
     midpoint, maximum and adjusted maximum respectively), assuming that: (a)
     shareholder approval of the recognition plan is received; (b) the shares
     were acquired by the recognition plan at the beginning of the period
     presented in open market purchases at $10.00 per share; (c) the amortized
     expense for the quarter ended March 31, 2000 is 5% (based on a five year
     amortization using the straight line method) of the amount contributed
     which is equal to the vested portion of the shares based on the average
     shares to be vested during the year; and (d) the effective tax rate
     applicable to such employee compensation expense is 40.0%. Unvested shares
     under the recognition plan are excluded from the basic earnings per share
     calculation and included in the diluted earnings per share calculation only
     if they are dilutive under the treasury stock method. Bank Mutual assumes
     that 20% of the recognition plan shares vest annually and that 19,555,
     22,099, 24,644 and 27,571 shares vest for the period ended March 31, 2000
     at the minimum, midpoint, maximum and adjusted maximum, respectively.
(g)  Assuming Bank Mutual were to fully convert, resulting in additional
     estimated adjusted net proceeds at the minimum, midpoint, maximum and
     adjusted maximum of $91.1 million, $102.2 million, $113.3 million and
     $126.0 million, respectively, which were invested at 5.93%, which
     represents the one year U. S. treasury note rate as of December 31, 1999,
     less tax effects, and all other assumptions noted above remained unchanged,
     the following ratios and amounts would result;

 (h) Basic earnings per share calculations are determined by (i) starting with
     the number of shares assumed to be sold in the conversion and stock
     offering excluding shares to be acquired by the ESOP and recognition plan,
     (ii) adding the number of shares to be issued to shareholders of First
     Northern, (iii) adding the number of shares to be issued to MHC, (iv)
     adding the average ESOP shares that have been committed for release during
     the period, and (v) adding the average recognition plan shares assumed
     vested during the period. The unvested recognition plan shares are deemed
     to be for future services and not dilutive under the treasury stock method.
     Book value per share calculations are determined by (i) starting with the
     number of shares assumed to be sold in the stock offering (ii) adding the
     number of shares to be

BANK MUTUAL CORPORATION
PRO FORMA FOR STOCK OFFERING
DECEMBER 31, 1999

(a)  Assumes an increase in the number of shares due to a 15% increase in the
     maximum of the offering range to reflect changes in market and financial
     conditions before the conversion and stock offering is completed or to fill
     the order of the employee stock ownership plan.
(b)  Estimated adjusted proceeds consist of the estimated net conversion
     proceeds, minus (i) the proceeds attributable to the purchase by Mutual
     Savings' employee stock ownership plan and (ii) the value of the shares to
     be purchased by Mutual Savings' recognition plan after the conversion and
     stock offering, subject to shareholder approval, at an assumed purchase
     price of $10.00 per share. Marketing fees and other issuance expenses
     consist of legal, accounting, printing and other fixed costs totaling
     $2,345,000 plus variable marketing fees based on 1.50% of gross proceeds
     less shares to be acquired by the ESOP.
(c)  Reflects the combined historical net earnings of Mutual Savings and First
     Northern for the year ended December 31, 1999, adjusted for the merger.
(d)  Consists of interest earned on net proceeds from the sale of minority
     ownership of Bank Mutual at 5.93%, which represents the one year U. S.
     treasury note rate as of December 31, 1999.
(e)  Bank Mutual assumes that 8% of the shares of common stock issued in the
     restructuring, the stock offering and the merger will be purchased by the
     ESOP (782,180, 883,976, 985,772 and 1,102,837 shares at the minimum,
     midpoint, maximum and adjusted maximum, respectively). Bank Mutual also
     assumes that the funds used to acquire such shares will be borrowed by the
     ESOP from Bank Mutual. Mutual Savings intends to make quarterly
     contributions to the ESOP over a ten-year period in an amount at least
     equal to the principle and interest requirements of the debt. The pro forma
     earnings assumes (i) that the loan to the ESOP is payable over ten years in
     equal installments of principle with the ESOP shares having an average fair
     value of $10.00 per share; (ii) that the loan to the ESOP bears interest at
     the Mutual Savings' prime interest rate; (iii) that the ESOP expense for
     the period is equivalent to the principal payment for the period and is
     made throughout the period (the interest expense paid by the Mutual Savings
     and the interest income recognized by Bank Mutual on the ESOP debt are
     eliminated in consolidation); (iv) that 78,218, 88,398, 98,577 and 110,284
     shares were committed to be released with respect to the year ended
     December 31, 1999, at the minimum, midpoint, maximum and adjusted maximum,
     respectively; (v) only the ESOP shares committed to be released during the
     period are considered outstanding for the purposes of the earnings per
     share calculations based on the average shares to be released during the
     year; and (vi) the effective tax rate is 40.0% for the period.
(f)  Bank Mutual assumes that 4% of the shares of common stock issued in the
     conversion, stock offering and merger will be purchased by the recognition
     plan (39l,090, 441,988, 492,886, and 551,419 shares at the minimum,
     midpoint, maximum

                                      -41-

     and adjusted maximum, respectively), assuming that: (a) shareholder
     approval of the recognition plan is received; (b) the shares were acquired
     by the recognition plan at the beginning of the period presented in open
     market purchases at $10.00 per share; (c) the amortized expense for the
     year ended December 31, 1999 is 20% (based on a five year amortization
     using the straight line method) of the amount contributed which is equal to
     the vested portion of the shares based on the average shares to be vested
     during the year; and (d) the effective tax rate applicable to such employee
     compensation expense is 40.0%. Unvested shares under the recognition plan
     are excluded from the basic earnings per share calculation and included in
     the diluted earnings per share calculation only if they are dilutive under
     the treasury stock method. Bank Mutual assumes that 20% of the recognition
     plan shares vest annually and that 78,218, 88,398, 98,577 and 110,284
     shares vested for the year ended December 31, 1999 at the minimum,
     midpoint, maximum and adjusted maximum, respectively.
(g)  Assuming Bank Mutual were to fully convert, resulting in additional
     estimated adjusted net proceeds at the minimum, midpoint, maximum and
     adjusted maximum of $91.1 million, $102.2 million, $113.3 million and
     $126.0 million, respectively, which were invested at 5.93%, which
     represents the one year U. S. treasury note rate as of December 31, 1999,
     less tax effects, and all other assumptions noted above remained unchanged,
     the following ratios and amounts would result;

             CERTAIN EFFECTS OF THE FIRST NORTHERN MERGER ON MUTUAL

         On a pro forma basis at March 31, 2000, assuming completion of the
First Northern merger, the restructuring and the stock offering, Bank Mutual
would have had total assets of $2.6 billion, total deposits of $1.9 billion, net
loans of $1.9 billion, total shareholders' equity of $250.2 million. For further
pro forma information, see "Pro Forma Data."

         Management of Mutual Savings believes that the First Northern merger
will be advantageous to Mutual's competitive posture, joining two banks with
contiguous market areas and compatible business philosophies and product mix.
The merger will permit Mutual to expand into growing northeastern Wisconsin
markets at a fair consideration and in a more efficient manner than establishing
new branches. Initially, the two banks will continue to operate separately.

         Mutual considers the experienced, forward-looking management of First
Northern to be a benefit of the merger. First Northern's CEO and three other
board members will join the board of Bank Mutual. It is anticipated that the
merger will allow the banks to eliminate certain duplicative costs and to
achieve potential economies of scale over time through the increased size and
efficiencies of the combined entity. Similarly, the increased size and
geographical market area should, over time, allow Mutual to expand products and
services and take advantage of greater cross-selling opportunities.

GEOGRAPHIC EXPANSION

         Mutual Savings and First Northern Savings currently operate in markets
that are, for the most part, contiguous and complementary to each other. Most of
Mutual Savings' offices are located in the southeastern, south central and
western part of Wisconsin. While Mutual has a relatively small presence in
northeastern Wisconsin, all of First Northern Savings' offices are located in
that area of the state. In particular, First Northern has a substantial presence
in the Fox River Valley region, and also includes surrounding rural and vacation
areas. The Fox River Valley region is anchored by the cities of Green Bay, where
First Northern has its headquarters and a substantial presence, and Appleton,
where Mutual Savings has its offices in the area. See "Business of Mutual
Savings Bank - Market Area." The First Northern acquisition would substantially
increase Mutual's presence in the northeastern part of the state, while Mutual
Savings expects that it would also retain its current offices in the region
after the First Northern merger.

         Mutual Savings believes that the northeastern part of Wisconsin is an
attractive area for growth. It is the third largest population concentration in
the state, and includes a variety of commercial, industrial, service and
recreational businesses.

IMPACT ON DEPOSITS

         Mutual Savings and First Northern Savings have relatively similar
deposit mixes and interest rates paid on those deposits.

operate as separate financial institutions, Mutual expects that certain deposit
products which currently are offered by only one of the savings banks may now be
offered by both. Thus, both Mutual Savings and First Northern Savings will have
the benefit of the other's experience.

         Mutual expects that customer retention will be maximized because both
the institutions anticipate keeping open all branch offices after the merger,
under the existing names. Because the two companies have relatively similar
deposit and pricing strategies, Mutual does not expect that changes, if any,
which may be made by First Northern Savings will cause a significant deposit run
off.

IMPACT ON LOAN PORTFOLIO

         Mutual Savings' and First Northern Savings' loan products and lending
operations are relatively similar, although Mutual Savings has a higher
percentage of first mortgage loans than First Northern Savings, and First
Northern Savings has a higher percentage of consumer loans. The following table
presents the composition of Mutual Savings' and First Northern Savings' loan
portfolios in dollar amounts and in percentages of the total portfolio at March
31, 2000. We have used several specific categories in this table than we have in
other tables in this prospectus to help illustrate the comparison between the
two institutions.

         First Northern Savings has a higher level of consumer loans than Mutual
Savings, particularly of automobile loans. Most of these are indirect automobile
loans originated by First Northern through a joint venture with another
financial institution. First Northern Savings has experienced minimal
delinquencies under this program; Mutual expects to continue the program after
the First Northern merger. First Northern Savings' "other" consumer loans
include loans secured by boats, recreational vehicles and snowmobiles as a
consequence of the vacation and recreational regions which are served by First
Northern.

         The weighted average interest rates on Mutual Savings' and First
Northern Savings' loans is generally consistent by loan type, with several
exceptions. The average rate on First Northern Savings' home equity lines of
credit is higher than Mutual Savings', primarily as a result of the lower
average credit line. Conversely, the weighted average rate on First Northern's
automobile loans is lower than Mutual Savings'. That difference results both
because First Northern's joint venture company absorbs losses on this portfolio,
which are then reflected at First Northern in the net yield rather than as
written off assets, and as a result of the more aggressive automobile loan
pricing by that joint venture.

         Both First Northern's and Mutual Savings' non-performing loan and asset
ratios reflect strong asset quality.

         Mutual believes that, over time, the First Northern merger will provide
additional lending opportunities to the combined enterprise. Mutual intends to
augment its consumer lending with programs currently offered by First Northern
Savings. Similarly, Mutual believes that the expanded customer and geographical
base will provide further opportunities for commercial real estate and
commercial business lending in which Mutual Savings and First Northern Savings
intend to expand. Mutual also expects to minimize customer disruption to First
Northern Savings' customers by retaining First Northern Savings as a separate
entity, whose local loan officers will retain authority to make most credit
decisions in its market area. Also, a larger institution will be better able to
diversify its portfolio since it has a larger customer base, can more readily
hire experienced staff, and leverage greater resources.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         This discussion and analysis reflects Mutual Savings' consolidated
financial statements and other relevant statistical data and is intended to
enhance your understanding of our financial condition and results of operations.
You should read the information in this section in conjunction with Mutual
Savings' consolidated financial statements and accompanying notes to
consolidated financial statements beginning on page F-1 of this prospectus, and
the other statistical data provided elsewhere in this prospectus.

GENERAL

         Mutual Savings' results of operations depend primarily on net interest
income. Net interest income is the difference between the interest income on
interest-earning assets, which for Mutual Savings primarily are loans and
mortgage-related and investment securities, and interest expense on
interest-bearing liabilities, which for Mutual Savings primarily are deposits
and borrowings. Our results of operations are also affected by our provision for
loan losses, non-interest income, and non-interest expense. Non-interest income
consists mainly of service fees and charges, gains on sales of loans held for
sale and insurance, securities and annuity commissions. Non-interest expense
consists primarily of salaries and employee benefits, occupancy expenses and
other general and administrative expenses, and amortization of intangible
assets.

         Our results of operations may also be affected significantly by general
and local economic and competitive conditions, particularly changes in market
interest rates, government policies, and actions of regulatory authorities.
Future changes in applicable law, regulations or government policies may
materially impact us. Additionally, our lending activity is concentrated in
loans secured by real estate located in Wisconsin and/or to Wisconsin borrowers.
Accordingly, our results of operations are affected by regional market and
economic conditions.

MANAGEMENT STRATEGY

         Mutual Savings' operating strategy is to succeed as a well-capitalized,
profitable community bank. We seek to accomplish this goal by:

                    -  maintaining a community orientation and providing quality
                       customer service;
                    -  expanding our market area;
                    -  continuing our commitment to residential lending, while
                       diversifying our portfolio;
                    -  managing credit risk;
                    -  promoting core deposit accounts;
                    -  limiting exposure to interest rate risk; and
                    -  controlling expenses.

         First Northern's operating strategy is similar to Mutual Savings'
strategy. Although the two banks initially will operate separately after the
restructuring, their business philosophies will continue to be complementary.

MANAGEMENT OF INTEREST RATE RISK

         Mutual Savings' ability to maintain net interest income depends upon
earning a higher yield on assets than the rates we pay on deposits and
borrowings. Fluctuations in interest rates will ultimately impact both our level
of income and expense recorded on a large portion of our assets and liabilities.
Fluctuations in interest rates will also affect the market value of all
interest-earning assets, other than those which possess a short term to
maturity.

         We have attempted to reduce our interest rate risk by emphasizing the
origination of ARM loans and by selling a majority of our longer-than-15 year
fixed rate mortgage loan originations. During the past few years we have
retained


                                      -49-

<PAGE>   52



15-year fixed rate mortgage loans in our portfolio. It is our opinion that the
enhanced yield and cash flows offered by this product offset the amount of
interest rate risk that is assumed. For the year ended December 31, 1999, we
originated $96.4 million of fixed rate one- to four-family first mortgage loans,
or 63.1% of total one-to-four family first mortgage originations, of which $57.4
million were sold with servicing retained. In managing our investment
securities, a relatively high proportion of the portfolio is retained in
securities, with concentration in fixed rate investments having a weighted
average remaining life of 83 months at March 31, 2000. We believe these
strategies have reduced income due to lower initial yields on these investments
in comparison to longer term fixed rate investments. However, we believe that
reducing our exposure to interest rate fluctuations will enhance long-term
profitability.

         For the first quarter of 2000, we originated $4.1 million of fixed
rate, one-to-four family first mortgage loans, or 18.9% of total one-to-four
family first mortgage originations, of which we sold $1.1 million with servicing
retained. As interest rates have risen, more borrowers have selected adjustable
loans.

         Interest rate sensitivity is a measure of the difference between
amounts of interest-earning assets and interest-bearing liabilities which either
reprice or mature during a given period of time. The difference, or the interest
rate sensitivity "gap," provides an indication of the extent to which our
interest rate spread will be affected by changes in interest rates. For further
information about interest rate repricing, see "Gap Analysis".

         During 1998 and early 1999, we operated in a low interest rate
environment. In that environment we experienced both increased interest rate
competition related to loan originations and above-average prepayment rates
related to mortgage loans and mortgage-related securities, as borrowers
refinanced higher-rate loans. As a result we had to invest our excess liquidity
in short term low-yielding investments. This had an adverse impact on our
profitability. As interest rates began to rise later in 1999, we began to
re-deploy our excess liquidity into higher yielding investments.

         Due to the nature of our operations, we are not directly subject to
foreign currency exchange or commodity price risk. Instead, our real estate loan
portfolio, concentrated in Wisconsin, is subject to risks associated with the
local economy. We did not engage in any hedging transactions that use derivative
instruments (such as interest rate swaps and caps) during 1999 and did not have
any such hedging transactions in place at March 31, 2000. In the future, we may,
with approval of our board of directors, engage in hedging transactions
utilizing derivative instruments.

         We seek to coordinate asset and liability decisions so that, under
changing interest rate scenarios, earnings will remain within an acceptable
range.

         The primary objectives of our interest rate management strategy are to:

         -      maintain earnings and capital within self-imposed parameters
                over a range of possible interest rate environments;

         -      coordinate interest rate risk policies and procedures with other
                elements of our business plan, all within the context of the
                current business environment and our capital and liquidity
                requirements; and

         -      manage interest rate risk in a manner consistent with the
                approved guidelines and policies set by our board of directors.

         To achieve the objectives of managing interest rate risk, our
Asset/Liability committee meets periodically to discuss and monitor the market
interest rate environment and provides reports to the board of directors
monthly. This committee is chaired by the President and is comprised of members
of Mutual Savings' senior management.

         Historically, our lending activities have emphasized one- to
four-family first and second mortgage loans. Our primary source of funds has
been deposits and borrowings, consisting primarily of time deposits and
borrowings which have substantially shorter terms to maturity than the loan
portfolio. We have employed certain strategies to manage the interest rate risk
inherent in the asset/liability mix, including:



                                      -50-

<PAGE>   53



         -      emphasizing the origination of adjustable-rate and 15 year
                fixed-rate real estate loans for portfolio, and selling 30-year
                fixed rate loans;

         -      maintaining a significant level of investment securities and
                mortgage-related securities with a weighted average life of less
                than eight years or with interest rates that reprice in less
                than five years; and

         -      managing deposits and borrowings to provide stable funding.

         We believe that the frequent repricing of our adjustable-rate real
estate loans, the cash flows from our 15 year fixed-rate real estate loans, and
adjustable rate features and shorter durations of our investment securities,
reduce our exposure to interest rate fluctuations.

         GAP ANALYSIS. Repricing characteristics of assets and liabilities may
be analyzed by examining the extent to which such assets and liabilities are
"interest rate sensitive" and by monitoring a financial institution's interest
rate sensitivity "gap." An asset or liability is said to be "interest rate
sensitive" within a specific time period if it will mature or reprice within
that time period. The interest rate sensitivity gap is defined as the difference
between the amount of interest-bearing assets maturing or repricing within a
specific time period and the amount of interest-bearing liabilities maturing or
repricing within that same time period.

         A gap is considered positive when the amount of interest-earning assets
maturing or repricing within a specific time period exceeds the amount of
interest-bearing liabilities maturing or repricing within that specific time
period. A gap is considered negative when the amount of interest-bearing
liabilities maturing or repricing within a specific time period exceeds the
amount of interest-earning assets maturing or repricing within the same period.
During a period of rising interest rates, a financial institution with a
negative gap position would be expected, absent the effects of other factors, to
experience a greater increase in the costs of its liabilities relative to the
yields of its assets and thus a decrease in the institution's net interest
income. An institution with a positive gap position would be expected, absent
the effect of other factors, to experience the opposite result. Conversely,
during a period of falling interest rates, a negative gap would tend to result
in an increase in net interest income while a positive gap would tend to reduce
net interest income.

         At March 31, 2000, based on the assumptions below, our interest-bearing
liabilities maturing or repricing within one year exceeded our interest-earning
assets maturing or repricing within the same period by $97.5 million. This
represented a negative cumulative one-year interest rate sensitivity gap of
(5.6%), and a ratio of interest-earning assets maturing or repricing within one
year to interest-bearing liabilities maturing or repricing within one year of
85.4%. By maintaining a low gap percentage, we decrease the impact on earnings
due to fluctuations in market interest rates. For the time frame of the gap, our
assets and liabilities are generally repricing at the same time.

         The following table presents the amounts of our interest-earning assets
and interest-bearing liabilities outstanding at March 31, 2000, which we
anticipate to reprice or mature in each of the future time periods shown. Except
as stated below, we determined the amounts of assets and liabilities shown which
reprice or mature during a particular period in accordance with the earlier of
the term to repricing or the contractual maturity of the asset or liability. The
information presented in the following table is also based on the following
assumptions:

         1.     We assumed the following repayment rates applied to
                outstanding balances applied to the beginning of the period:
                           Mortgage loans:      15.5%
                           Consumer loans:      49.8%
                           Commercial loans:    39.6%

         2.     Anticipated cash flows for mortgage-related securities were
                obtained from an independent outside source.



                                      -51-

<PAGE>   54



         3.     We reported federal agency securities with call options, that
                we believed would be called, at the earlier of the next call
                date or contractual maturity date;

         4.     We reported savings, money market accounts and
                interest-bearing demand accounts that had no stated maturity
                using decay rates. The decay rates were calculated using an
                average of the Mutual Savings' most recent 12 months
                experience.

         5.     FHLB advances are reported at the earlier of call date or final
                maturity.

         However, changes in interest rates could affect the loan and investment
prepayment assumptions and deposit decay rates used in our analysis.

         The repayment assumption used for mortgage loans in (1) above was
adjusted from recent history due to the current rise in interest rates. In a
rising rate environment, prepayments on mortgage loans slow down significantly
as mortgage loan customers retain their low interest rate loans. Deposit decay
rates, as reflected in items (4) above, are based on Mutual Savings' recent
history. Deposit decay rates, prepayment rates and anticipated call dates can
have a significant impact on the estimated interest rate sensitivity gap. While
we believe that our assumptions are reasonable, they may not be indicative of
actual future deposit decay activity, loan and mortgage-related securities
prepayments, and the actual timing of federal agency calls.

</TABLE>


The methods used in the previous table have some shortcomings. For example,
although certain assets and liabilities may have similar maturities or periods
to repricing, they may react in different degrees to changes in market interest
rates. Interest rates on certain types of assets and liabilities may fluctuate
in advance of changes in market interest rates, while interest rates on other
types may lag behind changes in market rates. Certain assets, such as
adjustable-rate loans, have features which limit changes in interest rates on a
short-term basis and over the life of the loan. If interest rates change,
prepayment and early withdrawal levels would likely deviate significantly from
those assumed in calculating the table. Finally, the ability of borrowers to
make payments on their adjustable-rate loans may decrease if interest rates
increase.

     Present Value of Equity. In addition to the gap analysis table, we also use
a simulation model to monitor interest rate risk. This model reports the present
value of equity in different interest rate environments, assuming an
instantaneous and permanent interest rate shock to all interest rate-sensitive
assets and liabilities. The present value of equity is the difference between
the present value of expected cash flows of interest rate-sensitive assets and
liabilities. The changes in market value of assets and liabilities due to
changes in interest rates reflect the interest rate sensitivity of those assets
and liabilities as their values are derived from the characteristics of the
asset or liability (i.e., fixed rate, adjustable-rate, caps, floors) relative to
the current interest rate environment. For example, in a rising interest rate
environment the fair market value of a fixed rate asset will decline, whereas
the fair market

<PAGE>   56

value of an adjustable-rate asset, depending on its repricing characteristics,
may not decline. Increases in the market value of assets will increase the
present value of equity whereas decreases in market value of assets will
decrease the present value of equity. Conversely, increases in the market value
of liabilities will decrease the present value of equity whereas decreases in
the market value of liabilities will increase the present value of equity.

     The following table presents the estimated present value of equity over a
range of interest rate change scenarios at March 31, 2000. The present value
ratio shown in the table is the present value of equity as a percent of the
present value of total assets in each of the different rate environments. For
purposes of this table, we have made assumptions such as prepayment rates and
decay rates similar to those used for the gap analysis table.

</TABLE>


     As in the case of the gap analysis table, the methods we used in the
previous table have some shortcomings. This type of modeling requires that we
make assumptions which may not reflect the manner in which actual yields and
costs respond to changes in market interest rates. For example, we make
assumptions regarding the acceleration rate of the prepayment speeds of higher
yielding mortgage loans. Prepayments will accelerate in a falling rate
environment and the reverse will occur in a rising rate environment. We also
assume that decay rates on core deposits will accelerate in a rising rate
environment and the reverse in a falling rate environment. The table assumes
that we will take no action in response to the changes in interest rates, when
in practice rate changes on certain products, such as savings deposits, may lag
market changes. In addition, prepayment estimates and other assumptions within
the model are subjective in nature, involve uncertainties, and therefore cannot
be determined with precision. Accordingly, although the present value of equity
model may provide an estimate of our interest rate risk at a particular point in
time, such measurements are not intended to and do not provide a precise
forecast of the effect of changes in interest rates on our present value of
equity.

ANALYSIS OF NET INTEREST INCOME

     Net interest income represents the difference between the interest income
we earn on our interest-earning assets, primarily loans, mortgage-related
securities and investment securities, and the expense we pay on interest-bearing
liabilities, primarily time deposits and borrowings. Net interest income depends
on our volume of interest-earning assets and interest-bearing liabilities and
the interest rates we earned or paid on them.

     Average Balance Sheet. The following table presents certain information
regarding Mutual Savings' financial condition and net interest income for the
quarters ended March 31, 2000 and 1999, and the years 1999, 1998 and 1997. The
table presents the average yield on interest-earning assets and the average cost
of interest-bearing liabilities for the periods indicated. We derived the yields
and costs by dividing income or expense by the average balance of
interest-earnings assets or interest-bearing liabilities respectively, for the
periods shown. We derived average balances from daily balances over the periods
indicated. Interest income includes fees which we considered adjustments to
yields.

     RATE/VOLUME ANALYSIS. The following table presents the extent to which
changes in interest rates and changes in the volume of interest-earning assets
and interest-bearing liabilities have affected our interest income and interest
expense during the periods indicated. Information is provided in each category
with respect to:

     (1)  changes attributable to changes in volume (change in volume multiplied
          by prior rate);
     (2)  changes attributable to change in rate (changes in rate multiplied by
          prior volume); and
     (3)  the net change.

The changes attributable to the combined impact of volume and rate have been
allocated proportionately to the changes due to volume and the changes due to
rate.

COMPARISONS OF FINANCIAL CONDITION

     AT MARCH 31, 2000 AND DECEMBER 31, 1999

     Mutual Savings' total assets decreased $27.3 million, or 1.5% at March 31,
2000 from $1.77 billion at December 31, 1999.

     At March 31, 2000, loans increased $21.0 million, or 1.9%. Investment
securities available for sale decreased $9.6 million, or 16.6%. Mortgage-related
securities increased $98.4 million, or 26.3%, to $472.5 million at March 31,
2000 from $374.1 million at December 31, 1999. The change in loans reflects an
increase of $11.3 million in one- to four-family first mortgage loans and an
increase of $9.7 million in consumer loans and other loans. Loan originations
were supplemented by the purchase of mortgage-related securities. Cash and cash
equivalents decreased from $180.0 million to $39.7 million There was a shift of
funds from total cash and cash equivalents to higher- yielding loans and
securities. Cash was also used to manage the deposit outflow during the quarter
ended March 31, 2000.

     The reduction in total assets was primarily the result of a reduction of
$23.8 million, or 1.8%, in total deposits to $1.32 billion at March 31, 2000
from $1.34 billion at December 31, 1999. Interest-bearing deposits decreased
$31.0 million or 2.4%, to $1.27 billion at March 31, 2000. Non-interest-bearing
deposits increased $5.8 million, or 14.1% during the same period.
Interest-bearing deposit changes reflect competition from the equity and bond
markets, as well as increased competition for funds from traditional financial
institutions. Non-interest-bearing deposit changes reflect normal fluctuations
in demand type accounts and an increase in retail customer demand deposits at
the end of the quarter.

     Equity increased $100,000, or .5%, to $163.9 million at March 31, 2000,
from $163.8 million at December 31, 1999. The increase resulted from net income
of $3.0 million for the three months ended March 31, 2000, partially offset by a
$2.9 million unrealized loss on securities available for sale, primarily
resulting from increasing market interest rates.

     AT DECEMBER 31, 1999 AND 1998

     Mutual Savings' total assets decreased $103.4 million, or 5.5%, to $1.77
billion at December 31, 1999 from $1.87 billion at December 31, 1998.

     At December 31, 1999, loans increased $45.2 million, or 4.3%, to $1.08
billion, while investment securities available for sale decreased $58.8 million,
or 50.4%, to $57.8 million. Mortgage-related securities available for sale
increased $103.2 million, or 38.1%, to $374.1 million at December 31, 1999 from
$270.9 million at December 31, 1998. The changes in the first two categories
reflect our strategy of diversifying our loan originations to increase our
portfolio of home equity, multi-family and commercial real estate and commercial
business loans, by utilizing funds generated by maturing investments. Our
strategy of reinvesting short term investments into higher yielding mortgage
related securities is reflected in the increase in mortgage-related securities
and the decrease in cash and cash equivalents by $151.3 million or 45.8%, to
$179.0 million. The special $15.6 million write-off of intangible assets also
contributed to the reduction in assets.

     Total deposits decreased by $55.9 million, or 4.0% to $1.343 billion at
December 31, 1999, compared with $1.399 billion at December 31, 1998. Total time
deposits were $828.1 million at December 31, 1999, a decrease of 10.9% from
$929.4 million at December 31, 1998. This runoff is a reflection of our interest
rate risk strategy of replacing high cost deposits with lower cost sources of
funds when possible. This reduction in time deposits was partially offset by an
increase in money market deposits which increased by $71.8 million or 45.0% to
$231.2 million at December 31, 1999, compared with $159.4 million at December
31, 1998. Remaining deposits, comprised of savings, interest and
non-interest-bearing demand deposits decreased $26.4 million or 8.5% to 283.7

million at December 31, 1999 from $310.1 million at December 31, 1998. Also,
borrowings decreased $28.2 million or 10.4% to $242.7 million at December 31,
1999 from $270.8 million at December 31, 1998. This reduction in borrowings
reflects our strategy of managing net interest margin.

     Equity decreased $11.9 million, or 6.8%, to $163.8 million at December 31,
1999, from $175.7 million at December 31, 1998, primarily due to the $4.5
million net loss for 1999 and a $7.4 million unrealized loss on securities
available for sale.

COMPARISONS OF OPERATING RESULTS

     THREE MONTHS ENDED MARCH 31, 2000 AND 1999

     General. Net income for the quarter ended March 31, 2000 was $3.0 million
compared with $1.8 million for the quarter ended March 31, 1999. The $1.2
million, or 66.7% increase is primarily attributable to a $1.6 million increase
in net interest income and a $443,000 decrease in the amortization of intangible
assets, which was offset in part by a $744,000 increase in income taxes.

     Net Interest Income. Net interest income increased $1.6 million, or 16.4%,
to $11.6 million for the first quarter of 2000 compared with $10.0 million for
the first quarter of 1999 primarily due to decreased interest expense. On an
annualized basis, our net interest spread increased to 2.33% for the quarter
ended March 31, 2000 from 1.90% for the comparable quarter of 1999.
Additionally, our annualized net interest margin increased to 2.78% from 2.29%.

     Interest Income. Total interest income increased $691,000, or 2.3% to $29.8
million for the quarter ended March 31, 2000 compared with $29.1 million for the
quarter ended March 31, 1999. Interest on first mortgage loans decreased
$368,000 or 2.3%, to $15.5 million interest on consumer loans increased $868,000
million, or 24.3%, to $4.6 million, interest on investments decreased $3.3
million, or 64.9%, to $1.6 million, and interest on mortgage-related securities
increased $3.5 million, or 83.3%, to $7.7 million for the three months ended
March 31, 2000 compared with the corresponding prior year quarter.

     The average balance of total interest-earning assets decreased $76.0
million or 4.3% to $1.7 billion for the three months ended March 31, 2000
compared with $1.8 billion for the corresponding quarter of the prior year. This
decrease was primarily attributable to a $2.6 million, or 0.3%, increase in the
average balance of first mortgage loans, to $867.2 million, a $38.4 million, or
20.1% increase to $229.9 million in the average balance of consumer loans, a
$307.0 million, or 73.6% decrease to $110.1 million in the average balance of
investment securities, and a $190.0 million, or 71.5%, increase to $455.9
million in the average balance of mortgage-related investments. These changes
reflect our strategy of emphasizing consumer loans and re-deploying excess
liquidity into higher earning mortgage-related investments.

     For the three months ended March 31, 2000, the impact on interest income
from the decrease in the average balance of total interest-earning assets was
offset by a 47 basis point increase in the annualized average yield on total
interest-earning assets to 7.12% compared with 6.65% for the corresponding
quarter in the prior year. The re-deployment of lower yielding investments into
higher earning mortgage-related investments and the increased production of
consumer loans resulted in the higher yield of our interest-earning assets for
the three months ended March 31, 2000.

     Interest Expense. Interest expense on deposits decreased $812,000, or 5.2%,
to $14.8 million for the first quarter of 2000 from $15.6 million for the first
quarter of 1999. Interest on time deposits, which accounted for 73.4% of
interest on deposits for the quarter ended March 31, 2000, decreased $1.5
million, or 12.4%, to $10.9 million from the corresponding period of the prior
year.


                                      -58-


<PAGE>   61

     The average balance of total interest-bearing liabilities decreased $91.4
million, or 5.7%, to $1.52 billion for the three months ended March 31, 2000
compared with $1.61 billion for the corresponding quarter of the prior year. We
experienced a decrease of $52.4 million to $1.28 billion in the average balance
of deposits and a decrease of $39.0 million to $231.7 million in borrowings. The
impact on interest expense from the decrease in the average balance of total
interest-bearing liabilities was partially offset, however, by a 3 basis point
increase in the annualized average cost of total interest-bearing liabilities to
4.79% compared with 4.76% for the first quarter of 1999. The annualized average
cost of deposits decreased five basis points to 4.61% compared with 4.66% for
the first quarter of 1999, reflecting our decision to allow the highest yielding
deposits to run off. The annualized average cost of borrowings increased 64
basis points to 5.83% for the first quarter of 2000, compared with 5.19% for the
corresponding period of the prior year. The increased cost of borrowings
reflects the upward pricing of our borrowings as a result of the higher interest
rate environment.

     Provision for Loan Losses. Our provision for losses was $76,000 for the
first quarter of 2000 and $39,000 for the corresponding period of the prior
year. The allowance for loan losses at March 31, 2000 was $7.0 million, or
190.4% of non-performing loans. Non-performing loans at March 31, 2000 were $3.7
million compared with $4.8 million at March 31, 1999. Future provisions for loan
losses will continue to be based upon our assessment of the overall loan
portfolio and the underlying collateral, trends in non-performing loans, current
economic conditions and other relevant factors in order to maintain the
allowance for loan losses at adequate levels to provide for estimated future
losses.

     Non-Interest Income. Total non-interest income, consisting of service fees,
gain on sale of loans and other income, decreased 6.6%, or $96,000, to $1.83
million for the first quarter of 2000 from $1.93 million for the first quarter
of 1999. The decrease in non-interest income is primarily attributable to a
decrease in gain on the sale of loans as a result of decreased loan originations
of fixed-rate mortgage loans with maturities greater than 15 years. The
origination of longer-term fixed-rate mortgages decreased due to the higher
interest rate environment.

     Non-Interest Expense. Total non-interest expense, consisting primarily of
salaries and employee benefits, occupancy expense and other operating expenses,
decreased $443,000, to $8.28 million, for the quarter ended March 31, 2000
compared with $8.33 million for the quarter ended March 31, 1999. This was
principally because amortization of intangible assets decreased $443,000 to
$235,000, for the quarter ended March 31, 2000 compared with $678,000 for the
comparable quarter of 1999.

     Our efficiency ratio, excluding amortization of intangible assets, for the
first quarter of 2000 was 61.37% compared with 69.30% for the corresponding
period in 1999. Our non-interest expense to average assets ratio was 1.89% for
the three months ended March 31, 2000 and 1.79% for the three months ended March
31, 1999.

     Income Taxes. Income tax expense increased $744,000, or 67.0%, to $1.9
million for the three months ended March 31, 2000 compared with $1.1 million for
the three months ended March 31, 1999, due to an increase in income before tax
expense. The effective tax rate was 37.85% and 37.64% for the three months ended
March 31, 2000 and 1999, respectively.

     YEARS ENDED DECEMBER 31, 1999 AND 1998

     General. Net loss was $4.5 million for 1999, a decrease of $15.7 million,
or 140.2%, compared with net income of $11.2 million for 1998. The decrease was
primarily attributable to a $2.5 million decrease in net interest income and a
$15.6 million increase in amortization of intangible assets, offset in part by a
$2.8 million decrease in income tax expense. The increase in amortization of
intangible assets was related to a valuation of the unidentifiable intangible
assets and deposit base intangible accounts resulting from the purchase of First
Federal Bancshares of Eau Claire in 1997. At that time, as a result of the
purchase method of accounting used in the transaction, intangible assets were
generated. It is the responsibility of management to re-evaluate the carrying
value of intangible assets on a periodic basis. This valuation process was
performed in the fourth quarter of 1999.

Using a present value calculation of the anticipated net income flows of future
years for the assets acquired, it was determined that the assets were overvalued
by $15.6 million. Accordingly, a write down was booked at that time. The effect
was a $13.6 million reduction in net income. See footnote 2 to Mutual Savings'
consolidated financial statements.

     Net Interest Income. Net interest income for 1999 decreased $2.5 million,
or 5.5%, to $43.0 million for 1999 compared with $45.5 million for 1998. Net
interest rate spread, the difference between the average yield on the average
balance of interest-earning assets and the average cost of the average balance
of interest-bearing liabilities, decreased 13 basis points to 2.03% for 1999
from 2.16% for the prior year. Net interest margin, represented by net interest
income divided by the average balance of interest-earning assets, decreased 14
basis points to 2.44% for 1999 compared with 2.58 % for 1998. These decreases
were primarily due to the investment of proceeds from the repayment and sale of
mortgage loans in short-term, lower-yielding investments as market rates
declined.

     Interest Income. Total interest income decreased $7.2 million, or 5.7%, to
$118.3 million for 1999 compared with $125.5 million for 1998. Interest and fees
on loans accounted decreased from $90.1 million for 1998 to $79.6 million for
1999. Interest and dividends on investment securities available for sale
increased $486,000, or 2.5%, to $20.2 million for 1999 compared with $19.7
million for 1998. Interest on mortgage-related securities available for sale
increased $2.8 million, or 17.8%, to $18.5 million for 1999 compared with $15.7
million for 1998.

     We experienced a $3.4 million, or 0.2%, decrease in the average balance of
total interest-earning assets. However, the mix of our earning assets changed
more significantly. The average balance of loans decreased $90.2 million, or
7.8%, to $1.07 billion for 1999 compared with $1.16 billion for 1998. This
decrease primarily reflects decreased origination and the large repayments of
adjustable rate loans refinanced with 30 year fixed rate loans which were
subsequently sold. The average balance of mortgage-related securities increased
$52.4 million, or 22.0%, to $290.8 million for 1999 compared with $238.3 million
for 1998. The average balance of investment securities increased $36.5 million,
or 10.5%, to $383.6 million for 1999 compared with $347.1 million for 1998.
These increases reflect our continued strategy of using our investments to
increase interest income while managing interest rate risk.

     The primary reason for the decrease in interest income was a 40 basis point
decrease in the average yield on interest-earning assets to 6.73% for 1999 from
7.13% for 1998. The average yield on loans decreased 33 basis points to 7.44%
for 1999 compared with 7.77% for the prior year. The average yield on
mortgage-related securities decreased 21 basis points to 6.36% for 1999 compared
with 6.57% for 1998. The average yield on investment securities decreased 35
basis points. to 5.03% for 1999 compared with 5.38% for 1998. The lower interest
rate environment along with the relatively flat yield curve that prevailed
during 1999 and the end of 1998 resulted in the downward repricing of our
interest rate-sensitive assets. In addition, the average yield on our assets was
affected by the refinancing of many of our existing loans to fixed rate mortgage
loans which were subsequently sold. The proceeds of loan repayments and loan
sales were invested in lower-yielding investment securities and mortgage-related
securities.

     Interest Expense. Interest expense on deposits decreased $4.1 million, or
6.3%, to $61.1 million for 1999 compared with $65.2 million for 1998. Interest
expense on time deposits decreased $6.9 million, or 12.9% to $46.5 million for
1999, down from $53.3 million for 1998. Interest expense on savings accounts
decreased $383,000 or 9.0% to $3.9 million for 1999 compared to $4.3 million for
1998. Interest expense on money market accounts increased $3.2 million or 48.5%
to $9.8 million for 1999 compared to $6.6 million for 1998. Interest expense on
borrowings decreased $504,000, or 3.5%, to $13.9 million compared to $14.4
million in 1998.

     The 5.8% overall decrease in interest expense was primarily attributable to
a decrease of 26 basis points in the average cost of interest-bearing
liabilities This decrease reflects a lower interest rate environment and our



                                      -60-

strategy of funding assets through competitive pricing of our deposit products
and allowing higher costing time deposits to run off when adverse market
conditions exist.

     Provision for Loan Losses. During 1999 we provided $350,000 for loan
losses, compared to $637,000 for 1998. Net loan charge-offs were approximately
$257,000 for 1999, compared to $977,000 in 1998. The allowance for loan losses,
which is established through a provision for loan losses charged against income
was $6.9 million at both December 31, 1999 and December 31, 1998.

     Non-interest Income. Non-interest income, consisting of service fees,
brokerage commissions, gain on sale of loans and other income, decreased
$456,000, or 5.4%, to $8.0 million for 1999 compared with $8.4 million for 1998.
Various factors contributed to the change, primarily a $598,000 increase in
brokerage commissions, a $648,000 decrease in loan fees and service charges due
to decreased loan originations, and a $528,000 decrease in gains on sales of
loans due to decreased loan sales.

     Non-interest Expense. Non-interest expense increased $15.8 million, or
44.5%, to $51.3 million during 1999 compared with $35.5 million for the prior
year. Amortization of intangible assets made up 98.7% of the increase in
non-interest expense. An increase in amortization of Intangible assets of $15.6
million, or 578%, to $18.3 million in 1999 compared to $2.7 million in 1998, was
a result of the special write-off of intangible assets from the 1997 First
Federal acquisition. The remaining increase was $206,000 or 0.6% to $33.0
million in 1999, compared to $32.8 million in 1998 for other non-interest
expense items, excluding amortization of intangible assets.

     Our efficiency ratio was 64.8% for 1999 compared with 60.8% for 1998. The
increase in the efficiency ratio reflects lower interest income as a result of
our high volume of lower yielding short-term investment securities rather than
an increase in operating expenses. The ratio of non-interest expense, excluding
amortization of intangible assets, to average assets was 1.79% for 1999 and
1.77% for 1998.

     Income Taxes. Income tax expense decreased $2.8 million or 42.4% to $3.8
million for 1999 compared to $6.6 million for 1998. Income tax expense in 1999
is significantly impacted by the non-deductibility of a substantial portion of
the amortization of intangible assets. Excluding this amortization, our
effective tax rate for 1999 was 38.9% compared to 37.1% in 1998.

     YEARS ENDED DECEMBER 31, 1998 AND 1997

     General. Net income was $11.2 million for 1998, an increase of $1.0
million, or 9.8%, compared with net income of $10.2 million for 1997. The
increase was primarily attributable to a $1.7 million increase in net interest
income, a reduction in provision for loan losses of $428,000, and an increase of
$2.3 million in total non-interest income offset by an increase in total
non-interest expense of $3.4 million.

     Net Interest Income. Net interest income for 1998 increased $1.7 million,
or 3.9%, to $45.5 million compared with $43.8 million for 1997. Net interest
income was increased by the full year of earning assets from the purchase of
First Federal. However, this increase was offset by a decrease in net interest
rate spread by 15 basis points to 2.16% for 1998 from 2.31% for the prior year.
Net interest margin decreased 18 basis points to 2.58% for 1998 compared with
2.76% for 1997. This reduction was caused by the investment of proceeds from
loan sales and repayments, including significant refinancings into
lower-yielding investments. Borrowed funds were utilized in 1998 to enhance net
interest income by using the proceeds to invest in mortgage-related securities
with a positive spread. This partially offset the negative effect from reduction
of the loan portfolio.

     Interest Income. Total interest income increased $9.5 million, or 8.2%, to
$125.5 million for 1998 compared with $116.0 million for 1997. Interest on
mortgage-related securities increased 52.4% to $15.7 million for 1998 compared
with $10.3 million for 1997. Interest and fees on loans decreased $3.5 million,
or 3.7%, to $90.1


                                      -61-

<PAGE>   64

million for 1998, compared with $93.6 million for the prior year. Additionally,
interest and dividends on investment securities available for sale increased
$7.6 million, or 62.8%, to $19.7 million for 1998 from $12.1 million for 1997.

     The increase in total interest income was primarily due to a $176.8
million, or 11.2%, increase in the average balance of total interest-earning
assets to $1.76 billion for 1998 compared with $1.58 billion for 1997. This
growth reflects the impact of the purchase of First Federal which occurred in
April 1997 and which was accounted for as a purchase. We purchased $539.7
million of loans in the acquisition. Growth in assets was funded by deposit
growth and by an increase in Federal Home Loan Bank borrowings, both of which
were also the result of the purchase of First Federal. The average balance of
net loans, however, decreased $53.2 million, or 4.4%, to $1.16 billion for 1998
compared with $1.21 billion for 1997, while the average balance of
mortgage-related securities increased $79.1 million, or 49.7%, to $238.3 million
for 1998 compared with $159.3 million for 1997. In addition, the average balance
of investment securities increased by $153.5 million, or 79.2%, to $347.1
million in 1998 compared with $193.7 million in 1997. In 1998, we experienced a
run off in mortgage loans. This was the result of customer loan prepayments.
Some ARM loans were refinanced to 30-year fixed rate mortgages. As part of our
interest rate risk strategy, these loans were subsequently sold.

     The average yield on interest-earning assets decreased to 7.13% for 1998
compared with 7.32% for 1997. The average yield on loans increased 5 basis
points, to 7.77% for 1998 from 7.72% for the prior year. The average yield on
mortgage-related securities increased 13 basis points to 6.57% for 1998 from
6.44% for 1997. The average yield on investment securities decreased 37 basis
points to 5.38% for 1998 from 5.65% for 1997.

     Interest Expense. Total interest expense increased $7.8 million or 10.8% to
$80.0 million in 1998 compared to $72.2 million in 1997. Interest expense on
deposits increased $4.3 million, or 7.1%, to $65.2 million for 1998 compared
with $60.9 million for 1997. Interest expense on time deposits, which accounted
for 81.7% of interest expense on deposits, increased $3.7 million, or 7.5%, to
$53.3 million for 1998 from $49.6 million for 1997. Interest expense on savings,
money market accounts and interest-bearing demand accounts increased $618,000,
or 5.5% to $11.9 million for 1998 compared to $11.3 million for 1998. Interest
expense on borrowings increased $3.5 million or 32.1% to $14.4 million in 1998
compared to $10.9 million in 1997.

     The overall increase in interest expense on deposits was primarily
attributable to an increase of $170.3 million, or 11.8%, in the average balance
of total interest-bearing liabilities to $1.6 billion for 1998 compared with
$1.4 billion for 1997. The increase reflects a full year of balances resulting
from the purchase of First Federal in April, 1997. The increase in
interest-bearing liabilities occurred in three major areas: money market
accounts increased $22.6 million, or 18.9%, to $141.9 million in 1998 compared
to $119.3 million in 1997; time deposits increased $63.7 million or 7.4% to
$927.2 million in 1998 compared with $863.5 million in 1997; and Federal Home
Loan Bank borrowings increased $79.5 million, or 41.5% to $270.8 in 1998
compared to $191.3 for 1997.

     The average cost of total interest-bearing liabilities decreased to 4.96%
for 1998 compared with 5.01% for 1997.

     Provision For Loan Losses. During 1998 and 1997, we provided $637,000 and
$1.1 million, respectively, for loan losses. Net loan charge-offs were $1.0
million for 1998 and $240,000 for 1997. This resulted in the allowance for loan
losses decreasing $340,000, or 4.7%, to $6.9 million at December 31, 1998, from
$7.2 million at December 31, 1997. The decrease in the provision reflects an
increase in charge-offs resulting from the additional losses recognized on loans
acquired in the purchase of First Federal. The reduction in total allowances was
more than offset by the reduction in the loan portfolio. Therefore, at December
31, 1998, the allowance for loan losses as a percentage of loans was 0.66%
compared with 0.57% at December 31, 1997. The allowance for loan losses was
101.9% of non-performing loans at December 31, 1998, compared with 72.1% at
December 31, 1997.

     Non-Interest Income. Total non-interest income for 1998 was $8.4 million,
an increase of $2.2 million, or 35.5%, from $6.2 million for 1997. The overall
increase is partially due to 1998 including a full year of income


                                      -62-

<PAGE>   65

resulting from the purchase of First Federal compared to 1997, which included 9
months of income from the purchase. We experienced a 9.0% increase in fees on
deposit accounts to $2.6 million in 1998 compared with $2.4 million in 1997.
Brokerage commissions increased $244,000, or 24.4%, increasing to $1.2 million
for 1998 compared to $1.0 million in 1997. Loan fees and service charges
increased $889,000, or 115.0% to $1.7 million in 1998 compared with $773,000 in
1997. Gain on sale of loans, due to increase volume in loan sales, increased
$539,000, or 1.11%, to $1.0 million in 1998 compared with $486,000 in 1997.
Other income increased $391,000 or 42.2% to $1.3 million in 1998 compared to
$927,000 in 1997.

     Non-Interest Expense. Total non-interest expense increased $3.4 million, or
10.6%, to $35.5 million during 1998 compared with $32.1 million for the prior
year. The overall increase is partially due to 1998 including a full year of
expenses resulting from the purchase of First Federal Bancshares compared to
1997 which included 9 months of expense. Salaries and employee benefits
increased $1.3 million, or 8.5%, to $16.6 million for 1998 compared with $15.3
million for 1997. Net occupancy expense increased $292,000 or 5.5% to $5.6
million in 1998 compared with $5.3 million in 1997. Other operating expense
increased $1.2 million or 23.5% to $6.3 million in 1998 compared with $5.1
million in 1997. Amortization of intangible assets constituted 23.4% of the $3.4
million increase in non-interest expense. The amortization of intangible assets
related to the First Federal acquisition was recorded for nine months during
1997 and for the full year in 1998. Amortization amounted to $2.7 million in
1998 compared with $1.9 million in 1997.

     The ratio of non-interest expense to average assets, excluding amortization
of intangible assets, was 1.77% for 1998 and 1.82% for 1997. Our efficiency
ratio, which excludes amortization of intangible assets, was 60.8% for 1998
compared with 60.3% for 1997.

     Income Taxes. Income tax expense decreased $38,000, or 0.6%, to $6.58
million for 1998 compared with $6.62 million for 1997, resulting in effective
tax rates of 37.1% and 39.4% for 1998 and 1997, respectively.

LIQUIDITY AND CAPITAL RESOURCES

     The term "liquidity" refers to our ability to generate adequate amounts of
cash to fund loan originations, loan purchases, deposit withdrawals and
operating expenses. Our primary sources of funds are deposits, scheduled
amortization and prepayments of loan principal and mortgage-related securities,
maturities and calls of investment securities, borrowings from the Federal Home
Loan Bank (the "FHLB") of Chicago and funds provided by our operations.

     Loan repayments and maturing investment securities are a relatively
predictable source of funds. However, deposit flows, calls of investment
securities and prepayments of loans and mortgage-related securities are strongly
influenced by interest rates, general and local economic conditions and
competition in the marketplace. These factors reduce the predictability of the
timing of these sources of funds.

     Our primary investing activities are the origination and purchase of one-
to four-family real estate loans, multi-family and commercial real estate loans,
home equity loans, other consumer loans, commercial business loans, the purchase
of mortgage-related securities, and to a lesser extent, the purchase of
investment securities. During 1999 we originated and purchased loans of
approximately $374.9 million and during 1998 we originated and purchased loans
of approximately $428.3 million. Purchases of mortgage-related securities were
$213.5 million for 1999 and $119.5 million for 1998, while purchases of
investment securities were $21.5 million for 1999 and $381.9 million for 1998.
In the first quarter of 2000, we originated and purchased loans of $74.4
million, and purchased $114 million in mortgage- related securities and $10
million in investment securities.

     These investing activities were funded by principal payments on mortgage
loans and mortgage-related securities, calls and maturities on investment
securities, borrowings and funds provided by our operating activities. Principal
repayments on loans and mortgage-related securities totaled $350.7 million
during 1999, compared to


                                      -63-

<PAGE>   66

$588.0 million during 1998. Maturities and calls of investment securities
totaled $65.0 million during 1999 and $378.9 million during 1998. Sales of
loans, mortgage-related securities and investment securities provided cash flows
of $111.1 million during 1999 and $116.8 million during 1998.

     At March 31, 2000, Mutual Savings had outstanding loan commitments to
borrowers of approximately $24.0 million, unused commercial lines of credit of
approximately $1.5 million and available home equity and overdraft lines of
credit of approximately $65.0 million. There were no outstanding commitments to
purchase securities at March 31, 2000. Total deposits decreased $23.8 million in
the first quarter of 2000, decreased $55.9 million during 1999 and increased
$36.5 million during 1998. Deposit flows are affected by the level of interest
rates, the interest rates and products offered by competitors and other factors.
Time deposit accounts scheduled to mature within one year were $545.3 million at
March 31, 2000. We are committed to maintaining a strong liquidity position;
therefore, we monitor our liquidity position on a daily basis. We anticipate
that we will have sufficient funds to meet current funding commitments.

     At March 31, 2000, we exceeded each of the applicable regulatory capital
requirements. Our leverage (tier 1) capital was $160.9 million, or 9.25%, at
March 31, 2000. In order to be classified as "well-capitalized" by the FDIC we
were required to have leverage (tier 1) capital of $87.0 million, or 5.00%. To
be classified as a well-capitalized bank by the FDIC, we must also have a
risk-based total capital ratio of 10.00%. At March 31, 2000, we had a risk-based
total capital ratio of 18.76%. See "Regulation -- Mutual Savings Federal
Regulation Prior to Restructuring -- Capital Requirements" for a discussion of
the regulatory capital requirements applicable to Mutual Savings and see
"Regulatory Capital Compliance" for information regarding the impact of the
offering on our capital position.

     It is anticipated that the restructuring and First Northern merger
transactions will result in a decrease in the capital of both Mutual Savings and
First Northern: See "Capitalization." Following the transactions, however, the
banks are expected to satisfy the FDIC criteria to be categorized as
"well-capitalized."

     We do not anticipate any material capital expenditures, nor do we have any
balloon or other payments due on any long-term obligations or any off-balance
sheet items other than the commitments and unused lines of credit noted above.

RECENT ACCOUNTING PRONOUNCEMENTS

     In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, "Accounting for Stock- Based Compensation." Under SFAS No. 123, an entity
may elect to recognize stock-based compensation expense based on the fair value
of the awards, or they may elect to account for stock-based compensation under
APB Opinion No. 25, "Accounting for Stock Issued to Employees." If an entity
elects to account for stock-based compensation under APB No. 25, it is not
required to recognize expense based on the fair value of the awards. However,
the entity must disclose in the financial statements the effects of SFAS No.
123, as if the recognition provisions of SFAS No. 123 were adopted.

     Currently, Mutual Savings does not provide stock-based compensation to its
employees. Upon completion of the restructuring, subject to shareholder
approval, we will establish certain stock-based compensation plans. If
established, we have evaluated the alternatives available under the provisions
of SFAS No. 123 and currently expect that we will not adopt the recognition
provisions of the statement, but will provide the required footnote disclosures.
Therefore, we do not expect that the adoption of SFAS No. 123 will have a
material impact on our financial position or results of operations.

     In February 1997, the FASB issued SFAS No. 128, "Earnings Per Share." This
statement established standards for computing and presenting earnings per share
(EPS) and applies to entities with publicly held common


                                      -64-

<PAGE>   67

stock or potential common stock. SFAS No. 128 simplifies the standards for
computing EPS previously found in APB Opinion No. 15, "Earnings Per Share," and
makes them more comparable with international EPS standards.

     Mutual Savings, as a mutual savings bank, does not have common stock
authorized, issued or outstanding and we do not calculate or present EPS. Upon
completion of the restructuring, we will calculate and present EPS in accordance
with SFAS No. 128.

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. It requires
that an entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at, fair value.

     SFAS No. 133, as amended, is effective for all quarters of those years
beginning after June 15, 2000. This statement may not be applied retroactively
to financial statements of prior periods. As Mutual Savings does not utilize
derivatives, we do not expect that our adoption of SFAS No. 133 will have a
material impact on our financial position or results of operations.

IMPACT OF INFLATION AND CHANGING PRICES

     The financial statements and accompanying notes of Mutual Savings have been
prepared in accordance with generally accepted accounting principles (GAAP).
GAAP generally requires the measurement of financial position and operating
results in terms of historical dollars without consideration for changes in the
relative purchasing power of money over time due to inflation. The impact of
inflation is reflected in the increased cost of our operations. Unlike
industrial companies, our assets and liabilities are primarily monetary in
nature. As a result, changes in market interest rates have a greater impact on
performance than do the effects of inflation.

                         BUSINESS OF MUTUAL SAVINGS BANK

GENERAL

     Mutual Savings is a community oriented financial institution which
emphasizes traditional financial services to individuals and businesses within
its market areas. Our principal business is attracting retail deposits from the
general public and investing those deposits, together with funds generated from
other operations, in residential mortgage loans, consumer loans, commercial real
estate loans, and commercial business loans. We also invest in various
mortgage-related securities and investment securities. The principal lending is
on one-to four-family, owner-occupied homes, home equity loans and lines of
credit, consumer loans, multi-family and commercial real estate loans, and
commercial business loans.

     Mutual Savings' revenues are derived principally from interest on our loans
and mortgage-related securities, interest and dividends on our investment
securities, and commissions on non-interest income (including loan servicing
fees, deposit servicing fees, gains on sales of loans held for sale and
insurance, securities and annuity sales). Our primary sources of funds are
deposits, borrowings, scheduled amortization and prepayments of loan principal
and mortgage-related securities, maturities and calls of investment securities
and funds provided by operations.

MARKET AREA

     Mutual Savings conducts its operations from 50 banking offices located in
21 counties throughout most of the state of Wisconsin, and one office in
Minnesota. At June 30, 1999 Mutual Savings had a 1.73% share of all


                                      -65-

<PAGE>   68

Wisconsin bank, savings bank and savings association deposits. The counties in
which Mutual Savings operates include 57% of the population of the state, which
provides us with access to a large base of potential customers. The markets in
which Mutual Savings operates vary, which provides diversity of opportunities
for Mutual Savings.

     As a result of the First Northern merger, Mutual will significantly expand
its presence. Together, Mutual Savings and First Northern Savings will then have
69 banking offices located in 28 counties in Wisconsin, in addition to the
Minnesota office. At June 30, 1999, the combined enterprise would have had a
2.42% share of all Wisconsin bank, savings bank and savings association
deposits. Counties in which Bank Mutual subsidiaries will operate will include
66% of the population of the state. On a pro forma basis, at March 31, 2000,
Bank Mutual would have been the fifth largest financial institution
headquartered in the state of Wisconsin, based on asset size.

     The largest concentration of Mutual Savings' offices is in the Milwaukee
metropolitan area which includes Milwaukee, Waukesha, Ozaukee and Washington
counties. There are 18 offices in this area. The Milwaukee metro area is the
largest population and commercial base in Wisconsin, representing approximately
28% of Wisconsin's population. The Milwaukee area has traditionally had an
extensive manufacturing economic base, which is diversifying into service and
technology based businesses. The Milwaukee metropolitan area grew at an average
annual rate of approximately 4.85% in population during the 1990s.

     Mutual Savings has four offices in the Madison area. Madison is the state
capital of Wisconsin and is the second largest metropolitan area in Wisconsin
representing approximately 8% of the state's population. Mutual Saving's ten
other south central Wisconsin offices are located in smaller cities that have
economic concentrations ranging from manufacturing to agriculture.

     The third largest concentration of Mutual Savings offices is in the
northwestern part of the state, largely resulting from the First Federal
acquisition in 1997. This part of the state has medium sized to smaller cities
and towns. Industry includes medium sized and small business, with a significant
agricultural component. The counties in which Mutual Savings' northwest region
offices are located hold 8% of the state's population. Mutual Savings' Minnesota
office is located near the Wisconsin state border on the eastern edge of the
Minneapolis-St. Paul metropolitan area.

     Recently, Mutual targeted the northeastern part of Wisconsin for a larger
presence. Mutual believes it will be able to accomplish this growth through the
First Northern merger because First Northern Savings' operations are located in
this part of the state. First Northern operates 19 offices in eight northeastern
counties that make up 12% of the state's population. Mutual Savings currently
has a relatively small presence in this area of the state.

COMPETITION

     Mutual Savings faces significant competition both in making loans and
attracting deposits. Wisconsin has many banks, savings banks, and savings and
loan associations which offer the same types of banking products as Mutual
Savings. Wisconsin also has an extensive tax-exempt credit union industry, whose
expanded powers have resulted in increased competition to financial
institutions.

     Many of Mutual Savings' competitors have greater resources than Mutual
does. Similarly, many competitors offer services that Mutual Savings does not
provide. For example, Mutual Savings does not provide trust or money management
services. However, Mutual does have an affiliate, Lake Financial and Insurance
Services, Inc. that offers securities, annuity and property and casualty
insurance services.

     Most of Mutual Savings' competition for loans traditionally has come from
commercial banks, savings banks, savings and loan associations and credit
unions. Increasingly, other types of companies, such as mortgage banking firms,
finance companies, insurance companies and other providers of financial services
also compete for these products. For deposits, Mutual Savings has also competed
with traditional financial institutions. However,


                                      -66-

<PAGE>   69

competition for deposits now also includes mutual funds, particularly short-term
money market funds, and brokerage firms and insurance companies. The recent
increase in electronic commerce now also increases competition from institutions
and other entities outside of Wisconsin.

LENDING ACTIVITIES

     Loan Portfolio Composition. Mutual Savings' loan portfolio primarily
consists of one-to four-family residential first mortgage loans. To a lesser
degree, the loan portfolio includes consumer and other loans, including home
equity credit lines and fixed-rate second mortgage loans, multi-family loans,
commercial real estate loans, and commercial business loans.

     At March 31, 2000, our loan portfolio totaled $1.1 billion, of which $889.1
million, or 79.0%, were first mortgage loans. Included in that total were $888.1
million of loans due after one year, of which 49.6% were adjustable rate
mortgage or ARM loans and 50.4% were fixed-rate loans with a weighted average
remaining maturity of 150 months. The remainder of our loans at March 31, 2000,
amounting to $236.0 million, or 21.0% of total loans, consisted of consumer
loans ($198.9 million or 17.7%) and commercial business loans ($37.0 million or
3.3%).

     We originate primarily ARM loans and up to 15 year fully amortizing fixed
rate loans for our own portfolio. We also offer longer term fixed rate
residential mortgages, most of which are immediately sold into the secondary
market.

     The loans that we originate are subject to federal and state laws and
regulations. The interest rates we charge on loans are affected principally by
the demand for loans, the supply of money available for lending purposes and the
interest rates offered by our competitors. These factors are in turn affected
by, among other things, economic conditions, monetary policies of the federal
government, including the Federal Reserve Board, legislative tax policies and
governmental budgetary matters.

</TABLE>

         Residential Mortgage Lending. Our primary lending activity has been the
origination of first mortgage loans secured by one- to four-family properties,
within our primary lending area, that are owner-occupied. At March 31, 2000,
$752.3 million or 66.9% of our gross loan portfolio consisted of loans secured
by one- to four-family residential properties. In addition to our loan
originations, we have purchased one- to four-family first mortgage loans of
$15.4 million in the first quarter of 2000 and $56.9 million in the year 1999.
Mutual reviews these loans for compliance with its underwriting standards, and
generally only invests in loans in the midwestern United States.

         We offer conventional fixed rate mortgage loans and ARM loans with
maturity dates which typically range from 15 to 30 years. Residential mortgage
loans generally are underwritten to Federal National Mortgage Association
Standards (FNMA) and other agency guidelines. All ARM loans and fixed rate loans
with maturities of up to 15 years are held in our portfolio. Fixed rate loans
greater than 15 years typically are sold without recourse, servicing retained,
into the secondary market. During the past few years we have generally not
charged loan origination fees. The interest rates charged on mortgage loan
originations at any given date will vary, depending upon conditions in the local
and secondary markets.

         We also originate "jumbo loans" in excess of the FNMA maximum loan
amount, which currently is $252,700. Fixed rate jumbo loans generally are sold
servicing released without recourse to secondary market purchasers of such
loans. ARM jumbo loans are underwritten in accordance with our underwriting
guidelines and are retained in our loan portfolio.

         Mortgage loan originations are solicited from real estate brokers,
builders, existing customers, community groups and residents of the local
communities located in our primary market area through our loan origination
staff. We also advertise our mortgage loan products through local newspapers,
periodicals and internal customer communications.

          We currently offer loans that conform to underwriting standards that
are based on standards specified by FNMA ("conforming loans") and also originate
a limited amount of non-conforming loans for our own portfolio or

                                      -70-
<PAGE>   73


for sale. Loans may be fixed-rate one- to four-family mortgage loans or
adjustable-rate one- to four-family mortgage loans with maturities of up to 30
years. The average size of our one- to four-family mortgage loans originated in
1999 was approximately $94,000, and in the first quarter of 2000 was $110,000.
The overall average size of our one- to four- family first mortgage loans was
approximately $60,000 at March 31, 2000. We are an approved seller/servicer for
FNMA and an approved servicer for the Federal Home Loan Mortgage Corporation
(FHLMC).

         The focus of our loan portfolio is the origination of 30-year ARM loans
with interest rates adjustable in one, two, three, or five years. ARM loans
typically are adjusted by a maximum of 200 points per adjustment period with a
lifetime cap of 12.9% Monthly payments of principal and interest are adjusted
when the interest rate adjusts. We do not offer ARM loans which provide for
negative amortization. The initial rates offered on ARM loans fluctuates with
general interest rate changes and are determined by secondary market pricing,
competitive conditions and our yield requirements. We currently utilize the
monthly average yield on United States treasury securities, adjusted to a
constant maturity of one year ("constant treasury maturity index") as the index
to determine the interest rate payable upon the adjustment date of our ARM
loans. Some of the ARM loans are granted with conversion options which provide
terms under which the borrower may convert the mortgage loan to a fixed rate
mortgage loan for a limited period early in the term of the ARM loan. The terms
at which the ARM loan may be converted to a fixed rate loan are established at
the date of loan origination and are set at a level allowing us to sell the ARM
loan into the secondary market upon conversion.

         ARM loans may pose credit risks different from the risks inherent in
fixed rate loans, primarily because as interest rates rise, the underlying
payments from the borrowers rise, thereby increasing the potential for payment
default. At the same time, the marketability of the underlying property may be
adversely affected by higher interest rates. In order to minimize the risk
associated with ARM loans, borrowers under the one year ARM programs generally
are qualified at no less than the maximum adjusted rate at the first adjustment.

         The volume and types of ARM loans we originate have been affected by
the level of market interest rates, competition, consumer preferences and the
availability of funds. During the past three years, we experienced a decreased
demand for ARM loans, versus fixed rate loans, due to the continued low interest
rate environment. Although we will continue to offer ARM loans, we cannot
guarantee that we will be able to originate a sufficient volume of ARM loans to
increase or maintain the proportion that these loans bear to our total loans.

         In addition to conventional fixed rate and ARM loans, we are authorized
to originate mortgages utilizing various government programs, including programs
offered by the Federal Housing Administration, the Federal Veterans
Administration, and Guaranteed Rural Housing. We also participate in two
state-sponsored mortgage programs operated by Wisconsin Housing and Economic
Development Authority (WHEDA) and Wisconsin Department of Veterans Affairs
(WDVA). We originate these state-sponsored loans as an agent and assign them to
the agency immediately after closing. Servicing is retained by Mutual on both
the WHEDA and WDVA loans.

         Upon receipt of a completed mortgage loan application from a
prospective borrower, a credit report is ordered, income and other information
is verified, and if necessary, additional financial information is requested. An
appraisal of the real estate to secure the loan is required which must be
performed by an independent, certified appraiser approved by the Board of
Directors. A title insurance policy is required on all real estate first
mortgage loans. Evidence of adequate hazard insurance and flood insurance, if
applicable, is required prior to closing. Borrowers are required to make e
monthly payments to fund principal and interest as well as private mortgage
insurance and flood insurance, if applicable. e With some exceptions for lower
loan-to-value ratio loans, borrowers also generally are required to escrow in
advance for real estate taxes and hazard insurance. We make disbursements for
these items from the escrow account as the obligations become due.

         In addition to our full documentation loan program, we process some
loans as reduced documentation loans. These loans are processed under the FNMA
alternative documentation program. We require applicants for


                                      -71-
<PAGE>   74


reduced documentation loans to complete a FNMA loan application and request
income, assets and debt information from the borrower. In addition to obtaining
outside vendor credit reports on all borrowers, we also look at other
information to ascertain the credit worthiness of the borrower. In most
instances, we utilize the FNMA "Desktop Underwriter" automated underwriting
process to further reduce the necessary documentation. For example, a simplified
appraisal may be used to verify the value of the property. All loans that are
process with reduced documentation conform to secondary market standards and are
generally salable.

         Our Underwriting Department reviews all pertinent information prior to
making a credit decision to approve or deny an application. All recommendations
to deny are reviewed by a designated officer of Mutual prior to the final
disposition of the loan application. Our lending policies generally limit the
maximum loan-to-value ratio on one- to four-family mortgage loans secured by
owner-occupied properties to 95% of the lesser of the appraised value or
purchase price of the property. Loans above 80% loan-to-value ratios are subject
to the availability of private mortgage insurance. Coverage is required to
reduce our exposure to less than 80% of value.

         Our originations of first mortgage loans amounted to $152.7 million in
1999, $288.5 million in 1998 and $163.5 million in 1997, and $22.0 million in
the first quarter of 2000. A significant number of our first mortgage loan
originations have been the result of refinancing of our existing loans due to
the relatively low interest rate levels over the past three years. Total
refinancings of our existing first mortgage loans were as follows:

         In addition to our standard mortgage and consumer credit products, we
have developed mortgage programs designed to specifically address the credit
needs of low- to moderate-income home mortgage applicants and first-time home
buyers. Among the features of the low- to moderate-income home mortgage and
first-time home buyer's programs are reduced rates, lower down payments, reduced
fees and closing costs, and generally less restrictive requirements for
qualification compared with our traditional one- to four-family mortgage loans.
For instance, certain of these programs currently provide for loans with up to
97% loan-to-value ratios and rates which are lower than our traditional mortgage
loans.

         Consumer Loans. We have been expanding our consumer loan portfolio
because higher yields can be obtained, there is strong consumer demand for such
products, and we have experienced relatively low delinquency and few losses on
such products. In addition, we believe that offering consumer loan products
helps to expand and create stronger ties to our existing customer base by
increasing the number of customer relationships and providing cross-marketing
opportunities. At March 31, 2000, $198.9 million, or 17.7%, of our gross loan
portfolio was in consumer loans. Consumer loan products offered within our
market areas include home equity loans, home equity lines of credit, and to a
lesser extent, automobile loans, recreational vehicle loans, marine loans,
deposit account loans, overdraft protection lines of credit, unsecured consumer
loans through the Mastercard and Visa credit card programs (offered through Elan
Financial Services) and federally guaranteed student loans.

         Our focus in consumer lending has been the origination of home equity
loans, home equity lines of credit and home improvement loans. At March 31,
2000, we had $160.2 million or 80.5% of the consumer loan portfolio in such
loans. Underwriting procedures for these loans include a comprehensive review of
the loan application, and require an acceptable credit rating and verification
of the value of the equity in the home and income of the

                                      -72-
<PAGE>   75

borrower. The loan-to-value ratio and debt ratios to income are determining
factors in the underwriting process. Home equity loan and home improvement loan
originations are developed through the use of direct mail, cross-sales to
existing customers, and advertisements in local newspapers.

         We originate both fixed rate and variable rate home equity loans and
home improvement loans with combined loan-to-value ratios to 100%. Loans above
80% combined loan to value ratios are subject to the availability of private
mortgage insurance. Pricing on fixed rate home equity and home improvement loans
is reviewed by senior management, and generally terms are in the three to
fifteen year range in order to minimize interest rate risk. During the quarter
ended March 31, 2000 we originated approximately $14 million of fixed rate
loans. These loans carry a weighted average written term of 8 years and a fixed
rate ranging from 6.95% to 12.25%. We also offer variable rate home equity and
home improvement loans. At March 31, 2000, $29.8 million or 27.5% of the home
equity and home improvement loan portfolio carried a variable rate. The variable
rate loans have a fixed rate for three years then adjust annually, with terms of
up to twenty years. Our home equity and home improvement loans are originated in
amounts which, together with the amount of the first mortgage, do not exceed
100% of the value of the property securing the loan.

         Our home equity credit line loans, which totaled $52.0 million, or
26.1% of total consumer loans at March 31, 2000, are adjustable-rate loans
secured by a first or second mortgage on owner-occupied one to four-family
residences located in the state of Wisconsin. Current interest rates on home
equity credit lines are tied to the prime rate, adjust monthly and range from
100 to 150 basis points over the prime rate, depending on the loan-to-value
ratio. Home equity line of credit loans are made for terms up to 10 years and
require a minimum monthly payment of the greater of $100 or 1 1/2% of the month
end balance. An annual fee is charged on home equity lines of credit.

         At March 31, 2000, student loans amounted to $28.6 million, or 14.4% of
our consumer loan portfolio. These loans are serviced by Great Lakes Higher
Education Servicing Corporation.

         Consumer loans may entail greater credit risk than residential mortgage
loans. At March 31, 2000, $1.3 million or approximately 0.55% of the consumer
loan portfolio was 90 days or more delinquent. Although the level of
delinquencies in our consumer loan portfolio generally has been low, there can
be no assurance that delinquencies will not increase in the future.

         Multi-family and Commercial Real Estate Loans. At March 31, 2000 our
multi-family and commercial real estate loan portfolio consisted of 160 loans
totaling $108.9 million or 9.7% of our gross loan portfolio. The multi-family
and commercial real estate loan portfolio consist of fixed rate, ARM and balloon
loans originated at prevailing market rates. This portfolio generally consists
of mortgages secured by apartment buildings, office buildings, warehouses,
industrial buildings and retail centers. ARM loans of this type are currently
being originated at 175 to 250 basis points above the rate on U.S. Treasury
securities for comparable maturities. These loans typically do not exceed 80% of
the lesser of the purchase price or an appraisal by an appraiser designated by
us. Balloon loans generally are amortized on a 15 to 25 year basis with a
typical loan term of three to ten years.

         Loans secured by multi-family and commercial real estate are granted
based on the income producing potential of the property and the financial
strength of the borrower. The net operating income, which is the income derived
from the operation of the property less all operating expenses, must be
sufficient to cover the payments relating to the outstanding debt. In most
cases, we obtain joint and several personal guarantees from the principals
involved. We generally require an assignment of rents or leases in order to be
assured that the cash flow from the project will be used to repay the debt.
Appraisals on properties securing multi-family and commercial real estate loans
are performed by independent state certified fee appraisers approved by the
board of directors. Title and hazard insurance are required as well as flood
insurance, if applicable. Environmental assessments are performed on all
multi-family and commercial real estate loans in excess of $500,000.

         At March 31, 2000, the largest outstanding loan on a multi-family
property was $7.1 million on a 240 unit apartment project located in Milwaukee,
Wisconsin. At the same date, the largest outstanding loan on a commercial real
estate property was $6.9 million on two office buildings located in Milwaukee,
Wisconsin. At March 31, 2000, these loans were current and performing in
accordance with their terms.

         Loans secured by multi-family and commercial real estate properties are
generally larger and involve a greater degree of credit risk than one- to
four-family residential mortgage loans. Such loans typically involve large
balances to single borrowers or groups of related borrowers. Because payments on
loans secured by multi-family and commercial real estate properties are often
dependent on the successful operation or management of the properties, repayment
of such loans may be subject to adverse conditions in the real estate market or
the economy. If the cash flow from the project decreases, or if leases are not
obtained or renewed, the borrower's ability to repay the loan may be impaired.

         Commercial Business Loans At March 31, 2000, our commercial business
loan portfolio consisted of loans totaling $37.0 million or 3.3% of our gross
loan portfolio. The commercial loan portfolio consists of loans to businesses
for equipment purchases, working capital lines of credit, debt refinancing, SBA
loans and domestic stand-by letters of credit. Typically, these loans are
secured by business assets and personal guarantees. We offer both variable and
fixed rate loans. Approximately 11.5% of the commercial business loans have an
interest rate adjusted monthly based on the prevailing prime rate. Term loans
are generally amortized over a three to seven year period. Fixed rates are
priced at a margin over the yield on US Treasury issues with maturities that
correspond to the maturities of the notes. All lines of credit and term loans
with balances over $500 thousand are reviewed annually. The largest commercial
business loan at March 31, 2000 had an outstanding balance of $13.5 million and
was secured by equipment and chattel paper. All payments under commercial
business loans were current as of March 31, 2000.

         Loan Approval Authority. For one- to four- family residential loans
sold into the secondary market, our underwriters are authorized by the board of
directors to approve loans processed through the FNMA "Desktop Underwriter"
automated underwriting system up to $252,700. For one-to four-family residential
loans held in portfolio, our underwriters are authorized by the board of
directors to approve loans processed through the FNMA "Desktop Underwriter"
automated underwriting system up to $150,000, provided the loan-to-value ratio
is 75% of less and the loan meets other specific underwriting criteria. All
other loans in excess of $80,000 must be approved by a senior officer.

         Consumer loan underwriters have individual loan approval authorities
ranging from $15,000 to $50,000. Loan applications exceeding $50,000 must be
approved by a senior officer. All home equity loans where the loan-to-value
ratio exceeds 80% and/or where the normal underwriting standards are not met
must be approved by a senior officer.

         The executive committee of the board of directors reviews on a monthly
basis all loans made, and the board ratifies actions taken by the committee.

         Multi-family and commercial loan proposals and multi-family and
commercial construction loan proposals are subject to approval of the executive
committee of the board. All loan decisions are subject to ratification by the
board at their monthly meetings.

         Any commercial business loan less than $50,000 may be approved by the
department head or a senior officer, and any two of those individuals may
approve loans in the amount of $50,000 to $100,000. All commercial business
loans in the amount of $100,000 or more are approved by the executive committee
of the board of directors and ratified by the board at their next meeting.

Asset Quality
                                      -74-
<PAGE>   77

         One of our key operating objectives has been and continues to be to
maintain a high level of asset quality. Through a variety of strategies,
including, but not limited to, borrower workout arrangements and aggressive
marketing of owned properties, we have been proactive in addressing problem and
non-performing assets. These strategies, as well as our emphasis on quality
mortgage underwriting, our maintenance of sound credit standards for new loan
originations and relatively favorable economic and real estate market conditions
have resulted in historically low delinquency ratios and, in recent years, a
reduction in non-performing assets. These factors have helped strengthen our
financial condition.

         Delinquent Loans and Foreclosed Assets. When a borrower fails to make
required payments on a loan, we take a number of steps to induce the borrower to
cure the delinquency and restore the loan to a current status. In the case of
one-to-four family mortgage loans, our mortgage servicing department is
responsible for collection procedures from the 15th day of delinquency through
the completion of foreclosure. Specific procedures include a late charge notice
being sent at the time a payment is over 15 days past due with a second notice
(in the form of a billing coupon) being sent before the payment becomes 30 days
past due. Once the account is 30 days past due, we attempt telephone contact
with the borrower. Letters are sent if contact has not been established by the
45th day of delinquency. On the 60th day of delinquency, attempts at telephone
contact continue and stronger letters, including foreclosure notices, are sent.
If telephone contact cannot be made, we send our property inspector to the
property.

         When contact is made with the borrower, we attempt to obtain full
payment or work out a repayment schedule to avoid foreclosure. All properties
are inspected prior to foreclosure approval. Most borrowers pay before the
deadline given and it is not necessary to start foreclosure action. If it is,
action starts when the loan is between the 90th and 120th day of delinquency. We
normally seek the shortest redemption period possible. If we obtain the property
at the foreclosure sale, we hold the properties as real estate owned. They are
marketed after an outside appraisal is obtained and any PMI claims are filed.
The collection procedures and guidelines as outlined by Federal National
Mortgage Association (FNMA), Federal Home Loan Mortgage Corporation (FHLMC),
Federal Housing Administration (FHA), Veterans Administration (VA), Department
of Veterans Affairs (DVA), Wisconsin Housing and Economic Development Authority
(WHEDA) and Farmers Home Administration (FmHA) are followed.

         The collection procedures for consumer loans, excluding student loans,
include our sending periodic late notices to a borrower once a loan is 15 days
past due. We attempt to make direct contact with a borrower once a loan becomes
30 days past due. Supervisory personnel in our Consumer Loan Collection
Department review loans 60 days or more delinquent on a regular basis. If
collection activity is unsuccessful after 90 days, we may charge-off a loan or
refer the matter to our legal counsel for further collection effort. Loans we
deem to be uncollectible are proposed for chargeoff by our Collection
Department. Charge-offs of consumer loans require the approval of our Consumer
Loan Manager and a senior officer. All student loans are serviced by Great Lakes
Higher Education Servicing Corporation which guarantees their servicing to
comply with all Department of Education Guidelines. Our student loan portfolio
is guaranteed by the Great Lakes Higher Education Guaranty Corporation, which is
reinsured by the U.S. Department of Education.

         The collection procedures for multi-family, commercial real estate and
commercial business loans include sending periodic late notices to a borrower
once a loan is past due. We attempt to make direct contact with a borrower once
a loan becomes 15 days past due. The manager of multi-family and commercial real
estate reviews loans 15 days or more delinquent on a regular basis. The
commercial banking manager reviews loans 10 days or more delinquent on a regular
basis. If collection activity is unsuccessful, we may refer the matter to our
legal counsel for further collection effort. After 90 days or sooner, loans we
deem to be uncollectible are proposed for repossession or foreclosure and
charge-off. This action requires the approval of our board of directors.

                                      -75-

     Our policies require that management continuously monitor the status of the
loan portfolio and report to the board of directors on a monthly basis. These
reports include information on delinquent loans and foreclosed real estate. The
following table presents information regarding loans delinquent for 60 days or
longer:

     Our $3.8 million in loans delinquent 90 days or more at March 31, 2000 were
comprised primarily of 24 one- to four-family first mortgage loans (including
FHA/VA first mortgage loans) with an average principal balance of approximately
$87,000. The largest non-performing asset at March 31, 2000 was a high-rise
condominium in Bloomington, Minnesota. The property is carried as foreclosed
real estate in the amount of $1.6 million, net of a specific loss allowance.
First Federal originally made a construction and development loan on the
building which contains forty-nine residential units and three commercial units.
Mutual Savings obtained title to the property in 1998. As of March 31, 2000,
nineteen residential units remained to be sold, including four residential units
that were under contract of sale. Mutual Savings does not anticipate further
loss.

The large increase in non-performing assets in 1997 is primarily a result of the
acquisition of First Federal in that year.

         With the exception of first mortgage loans insured or guaranteed by the
FHA, VA or Guaranteed Rural Housing (formerly FmHA), we stop accruing income on
loans when interest or principal payments are greater than 90 days in arrears or
earlier when the timely collectibility of such interest or principal is
doubtful. We designate loans on which we stop accruing income as non-accrual
loans and we reverse outstanding interest that we previously credited to income.
We may recognize income in the period that we collect it when the ultimate
collectibility of principal is no longer in doubt. We return a non-accrual loan
to accrual status when factors indicating doubtful collection no longer exist.

         All commercial real estate loans which are greater than 90 days past
due are considered to be impaired. Impaired loans are individually assessed to
determine whether a loan's carrying value is in excess of the fair value of the
collateral or the present value of the loan's cash flows discounted at the
loan's effective interest rate.

         At March 31, 2000 and December 31, 1999 and 1998, we had no loans
classified as impaired as defined in SFAS No. 114.

         Foreclosed real estate consists of property we acquired through
foreclosure or deed in lieu of foreclosure. Foreclosed real estate properties
are initially recorded at the lower of the recorded investment in the loan or
fair value. Thereafter, we carry foreclosed real estate at fair value less
estimated selling costs. Foreclosed real estate is inspected periodically.
Additional outside appraisals are obtained if we consider that appropriate.
Additional write-downs may occur if the property value deteriorates. These
additional write-downs are charged directly to current operations.

</TABLE>

         The allowance for loan losses has been determined in accordance with
generally accepted accounting principles, under which we are required to
maintain adequate allowances for loan losses. We are responsible for the timely
and periodic determination of the amount of the allowance required. We believe
that our allowance for loan losses is adequate to cover specifically
identifiable loan losses, as well as estimated losses inherent in our portfolio
for which certain losses are probable but not specifically identifiable.

         Loan loss allowances are reviewed monthly. General allowances are
maintained by the following categories for performing loans to provide for
unidentified inherent losses in the portfolios:


         - One-to-four family
         - Consumer
         - Multi-family and commercial real estate
         - Commercial business

         Allowance goals have been established by an internal risk evaluation by
loan category. Various factors are taken into consideration, including:
historical loss experience, economic factors and other factors, that, in
management's judgment would affect the collectibility of the portfolio as of the
evaluation date. Shortfalls in loan loss allowance are charged against
operations as provision for loan losses, to maintain reserves at the desired
levels.

         The appropriateness of the allowance is reviewed by senior management
on a monthly basis based upon its evaluation of then-existing economic and
business conditions affecting the key lending areas of Mutual Savings. Other
outside factors such as credit quality trends, collateral values, loan volumes
and concentrations, specific industry conditions within portfolio segments and
recent loss experience in particular segments of the portfolio that existed as
of the balance sheet date and the impact that such conditions were believed to
have had on the collectibility of the loan are also considered. Our board of
directors also reviews the loan loss allowances compared to the relative size of
the portfolio on a monthly basis.


                                      -78-

<PAGE>   81

         Delinquent and Non-performing loans. One-to-four family loans
delinquent more than 90 days, multi-family and commercial real estate loans more
than 60 days, consumer loans more than 90 days and commercial business loans
more than 60 days are reviewed and analyzed by senior officers on an individual
basis. Any potential loss is charged against reserves by establishing a
corresponding specific reserve for that loan from the general reserve.

         By following careful underwriting guidelines, Mutual Savings has
historically maintained low levels of non-performing loans to total loans. Our
ratio of non-performing loans to total loans at December 31, 1995 was 0.10%. It
increased after the of acquisition of First Federal to a level of 0.97% at
December 31, 1998. However, at December 31, 1999 the level dropped to 0.44%, and
further dropped to 0.37% at March 31, 2000, reflecting the resolution of the
majority of the problem loans acquired.

         We believe the primary risks inherent in our portfolio are possible
increases in interest rates, a possible decline in the economy, generally, and a
possible decline in real estate market values. Any one or a combination of these
events may adversely affect our loan portfolio resulting in increased
delinquencies and loan losses. Accordingly, and because of the increased
concentration of consumer loans, we have taken steps to increase our level of
loan loss allowances over the last 5 years. At March 31, 2000, the allowance for
loan losses as a percentage of total loans was 0.63% compared with 0.43% at
December 31, 1995. Furthermore, the increase in the allowance for loan losses
each year from 1995 to 1999 reflects our strategy of resolving non-performing
loans while providing adequate allowances for inherent losses in the portfolio
and identifying potential losses in a timely manner, as well as providing an
adequate allowance to reflect changes in the components of the portfolio during
that period.

         Although we believe that we have established and maintained the
allowance for loan losses at adequate levels, future additions may be necessary
if economic and other conditions in the future differ substantially from the
current operating environment. In addition, various regulatory agencies, as an
integral part of their examination process, periodically review our loan and
foreclosed real estate portfolios and the related allowance for loan losses and
valuation allowance for foreclosed real estate. One or more of these agencies,
specifically the FDIC or the OTS, may require us to increase the allowance for
loan losses or the valuation allowance for foreclosed real estate based on their
judgments of information available to them at the time of their examination,
thereby adversely affecting our results of operations.

INVESTMENT ACTIVITIES

         Investment Securities. The board of directors reviews and approves our
investment policy on an annual basis. Senior officers, as authorized by the
board of directors, implement this policy. The board of directors reviews our
investment activity on a monthly basis.

         Our investment objectives are to meet legal liquidity requirements,
generate a favorable return on investments without undue compromise to our other
objectives as stated in the business plan and establish acceptable levels of
interest rate risk, credit risk and investment portfolio concentrations.
Wisconsin chartered savings banks have authority to invest in various types of
assets, including U.S. Treasury obligations, securities of various federal
agencies, State and Municipal obligations, mortgage-related securities, mortgage
derivative securities, certain time deposits of insured banks and savings
institutions, certain bankers' acceptances, repurchase agreements, loans of
federal funds, and, subject to certain limits, corporate debt and equity
securities, commercial paper and mutual funds.

         Our investment policy allows participation in hedging strategies or the
use of financial futures, options or forward commitments or interest rate swaps
but only with prior approval of the board of directors and the State of
Wisconsin, Department of Financial Institutions. We did not have any such
hedging transactions in place at March 31, 2000. Our investment policy prohibits
the purchase of non-investment grade bonds. Our investment policy also provides
that we will not engage in any practice that the Federal Financial Institutions
Examination Council considers to be an unsuitable investment practice. In
addition, the policy provides that we shall attempt to maintain primary
liquidity consisting of investments in cash, cash in banks, federal funds
purchased and securities with remaining maturities of less than six months in an
amount equal to 4.0% of average daily deposits. At March 31, 2000, our primary
liquidity ratio was 4.0%. For information regarding the carrying values, yields
and maturities of our investment securities and mortgage-related securities, see
"-- Carrying Values, Yields and Maturities."

         We classify securities as trading, held to maturity, or available for
sale at the date of purchase. We currently do not have any held to maturity
securities, but if we did, they would be reported at cost, adjusted for
amortization of premium and accretion of discount. Available for sale securities
are reported at fair market value. We currently have no securities classified as
trading.

         Mortgage-related Securities. Most of our mortgage-related securities
are directly or indirectly insured or guaranteed by GNMA, FHLMC or FNMA. The
rest of the securities are private collateralized mortgage obligations (CMO's).
We classify our entire mortgage-related securities portfolio as available for
sale.

         At March 31, 2000, mortgage-related securities available for sale
totaled $472.5 million, or 27.1% of total assets. At March 31, 2000, the
mortgage-related securities portfolio had a weighted average yield of 6.77%. Of
the mortgage-related securities we held at March 31, 2000, $409.3 million, or
86.6%, had fixed rates and $63.1 million, or 13.4%, had adjustable-rates.
Mortgage-related securities at March 31, 2000 included real estate mortgage
investment conduits (REMICs), which are securities derived by reallocating cash
flows from mortgage pass-through securities or from pools of mortgage loans held
by a trust. REMICS are a form of, and are often referred to as CMO's.

         Our REMICs have fixed and variable coupon rates ranging from 5.47% to
8.00% and a weighted average yield of 6.68% at March 31, 2000. At March 31,
2000, REMICs totaled $139.1 million, which constituted 29.4% of the
mortgage-related securities portfolio, or 8.0% of total assets. Our REMICs had
an expected average life of 8.3 years at March 31, 2000. For a further
discussion of our investment policies, including those for mortgage-related
securities, see "- Investment Securities." Purchases of mortgage-related
securities may decline in the future to offset any significant increase in
demand for one- to four-family mortgage loans and other loans.

         Mortgage-related securities generally yield less than the loans that
underlie such securities because of the cost of payment guarantees or credit
enhancements that reduce credit risk. However, mortgage-related securities are
more liquid than individual mortgage loans. In general, mortgage-related
securities issued or guaranteed by GNMA, FHLMC and FNMA are weighted at no more
than 20% for risk-based capital purposes, compared to the 50% risk weighting
assigned to most non-securitized residential mortgage loans.

         While mortgage-related securities carry a reduced credit risk as
compared to whole loans, they remain subject to the risk of a fluctuating
interest rate environment. Along with other factors, such as the geographic
distribution of the underlying mortgage loans, changes in interest rates may
alter the prepayment rate of those mortgage loans and affect both the prepayment
rates and value of mortgage-related securities.

SOURCES OF FUNDS

         General. Deposits, scheduled amortization and prepayments of loan
principal and mortgage-related securities, maturities and calls of investments
securities, Federal Home Loan Bank borrowings and funds provided by operations
are our primary sources of funds for use in lending, investing and for other
general purposes. We currently do not use reverse repurchase agreements as
sources of funds. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -Liquidity and Capital Resources."

         Deposits. We offer a variety of deposit accounts having a range of
interest rates and terms. We currently offer regular savings deposits
(consisting of passbook and statement savings accounts), interest-bearing demand
accounts, non-interest-bearing demand accounts, money market accounts and time
deposits. We also offer IRA and Keogh time deposit accounts.

         Deposit flows are influenced significantly by general and local
economic conditions, changes in prevailing interest rates, pricing of deposits
and competition. Our deposits are primarily obtained from areas surrounding our
offices and we rely primarily on paying competitive rates, service and
long-standing relationships with customers to attract and retain these deposits.
We do not use brokers to obtain deposits.

         When we determine our deposit rates, we consider local competition,
U.S. Treasury securities offerings and the rates charged on other sources of
funds. Core deposits (defined as regular savings deposits, money market accounts
and demand accounts) represented 39.3% of total deposits on March 31, 2000. At
March 31, 2000, time deposits with remaining terms to maturity of less than one
year amounted to $545.3 million. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations - Analysis of Net Interest Income"

     Borrowings. We borrow funds to finance our lending and investing
activities. Substantially all of our borrowings take the form of advances from
the Federal Home Loan Bank of Chicago. At March 31, 2000 we had no borrowings of
less than one year. We have pledged certain loans receivable as blanket
collateral for these advances and future advances. The Federal Home Loan Bank
offers a variety of borrowing options with fixed or variable rates, flexible
repayment options and fixed or callable terms. We choose the rate, repayment
option and term to fit the purpose of the borrowing

   * - Date originally opened by an acquired institution

         In addition, Mutual Savings owns two parcels of undeveloped land
through its MC Development subsidiary. The 15 acre Brown Deer parcel is
comprised of four lots consisting of 2.9 to 4.3 acres and was part of a larger
property that was acquired in 1988 to accommodate the construction of a new
corporate headquarters building. Each of the lots is available for sale and is
designed to accommodate 60,000 to 75,000 square foot office buildings. The net
book value of the four lots is $1,590,000. The 318 acre Oconomowoc parcel was
held by an acquired institution that obtained it through a foreclosure. It is
located in an area of the City of Oconomowoc that has seen considerable
residential development. All of the necessary utilities are available to the
property and it will be marketed for residential development in a manner that
will attempt to maximize its potential value. The parcel has a net book value of
$345,000.

LEGAL PROCEEDINGS

         Mutual is not involved in any pending legal proceedings other than
routine legal proceedings occurring in the ordinary course of business. We
believe that these routine legal proceedings, in the aggregate, are immaterial
to our financial condition and results of operations.

PERSONNEL

         As of March 31, 2000, Mutual had 488 full-time employees and 107
part-time employees. The employees are not represented by a collective
bargaining unit and we consider our relationship with our employees to be good.


                                   MANAGEMENT

MANAGEMENT STRUCTURE

         Bank Mutual's directors and executive officers initially will be
persons who are now directors or executive officers of Mutual Savings or First
Northern Savings. We expect that Bank Mutual will continue to have directors and
executive officers who have similar positions with Mutual Savings or First
Northern Savings unless and until there is a business reason to establish
separate management structures.

         Under Mutual Savings' current form of organization, it is governed by a
board of directors which is chosen by the depositors of Mutual. After the
restructuring, Mutual Savings will be governed by a board of directors elected
by Bank Mutual as its sole shareholder. In turn, the board of directors of Bank
Mutual will be chosen by its shareholders. Because the MHC will then own a
majority of the shares of Bank Mutual and because cumulative voting for
directors will not be permitted, the MHC will be in a position to elect all of
the directors of Bank Mutual. The directors of the MHC will be chosen by the
deposits of Mutual Savings. Initially, the board of directors of the MHC will be
the same as the board of directors of Bank Mutual.

COMPOSITION OF BOARDS OF DIRECTORS

         Upon the restructuring, Bank Mutual will have a board of directors
consisting of not less than five nor more than 15 directors. Each will belong to
one of three classes which was staggered three-year term of office. The classes
will be as nearly as equal as possible. At each of Bank Mutual's annual meetings
of shareholders, shareholders will elect directors to fill the seats of the
directors whose terms expire in that year and any other vacant seats.

         The seven current directors of Mutual Savings will be initial directors
of the MHC and Bank Mutual. Under the First Northern merger agreement, Mutual
has committed that four of the six directors of First Northern will be elected
to Bank Mutual and the MHC Board of Directors. Mutual intends to elect Michael
D. Meeuwsen, the CEO of First Northern, as one of these directors; the other
three have not yet been chosen but will be designated by Mutual prior to the
First Northern merger.

MUTUAL'S CURRENT DIRECTORS

         The following table presents the following information: the names of
Mutual Savings' directors, all of whom will be initial directors of Bank Mutual
and the MHC; their ages on August 15, 2000; their position(s) with Mutual; the
years when they began serving as directors of Mutual Savings; and when their
terms of office as directors of Bank Mutual and the MHC will expire. All of
these persons will have begun service as Bank Mutual directors in 2000.

         MICHAEL D. MEEUWSEN, age 46, is the president and chief executive
officer of First Northern and of First Northern Savings. Under the First
Northern merger agreement, Mr. Meeuwsen also will be elected as an additional
director of Mutual Savings upon the First Northern merger.

         Unless we give prior experience, each of these individuals has held the
identified current position for at least five years.

MEETINGS OF THE BOARD OF DIRECTORS AND ITS COMMITTEES

         Mutual Savings' board of directors currently meets on a monthly basis
and may hold additional special meetings. During 1999, Mutual Savings board held
12 regular meetings. Going forward, Bank Mutual expects that its, and the MHC's,
board will meet four times a year, with special meetings as needed.

         The board of directors of Bank Mutual will maintain Executive, Audit
and Compensation Committees. The Executive Committee will exercise the powers of
the board between its meetings. The Audit Committee will review the annual audit
prepared by the independent accountants, recommend the appointment of
accountants and receive reports from the internal audit department. It will
consist solely of independent directors. The Compensation Committee will provide
advice and recommendations to the Board of Directors in the areas of employee
salaries and benefit programs. It also will consist of independent directors.
Committee membership has not yet been determined.

         The Bank Mutual bylaws provide that the board of directors as a whole
will act as the Nominating Committee. As such, the board will consider
appropriate nominees for any vacancy on the Bank Mutual board of directors, and
shareholders should forward any nominations to the board.

DIRECTOR COMPENSATION

         Meeting Fees. Mutual Savings pays an annual retainer fee to each of its
non-management directors. Each of the directors receives a fee for attendance at
each board meeting. Each non-management director receives a fee for attendance
at each meeting of a committee of which the director is a member. Under an
arrangement pre-dating the establishment of the current payment structure, Mr.
Dwyer receives a fee for directors' and Executive Committee meetings for each
month regardless of attendance.

     The following table sets forth the retainer and meeting fees in effect for
both 2000 and 1999:

           Annual Retainer:                              $10,000
           Meeting Fees:
                  Board                                   $1,000
                  Executive Committee                       $700
                  Audit Committee                           none
                  Advertising Committee                     $150
                  Finance Committee                         $150
</TABLE>

         Deferred Compensation. Mutual Savings also maintains a deferred
compensation plan for each of its non-management directors. Directors who have
provided at least five years of service to Mutual Savings will be paid $1,000
per month for 10 years after their retirement from the Mutual Savings' board.
All of the existing directors' benefits have vested. In the event a director
dies prior to completion of these payments, payments will go to the director's
heirs. Mutual Savings has funded these arrangements through "rabbi trust"
arrangements, and based on actuarial analyses believes these obligations are
adequately funded.

         Bank Mutual. Going forward, the MHC and Bank Mutual will establish new
compensation packages for their directors. It is expected that the boards of
both entities will meet on the same day; there will not be duplicate payments
for board meetings held on the same day.

DEFINED BENEFIT RETIREMENT PLANS

         Mutual Savings maintains a qualified defined benefit pension plan that
covers substantially all employees who are age 21 or over and who have at least
one year of service. Pension benefits are based on the participant's average
annual compensation (salary and bonus) and years of credited service. Years of
credited service in the qualified defined benefit pension plan begin at date of
participation in the plan. Benefits are determined in the form of a ten year
certain and life annuity.

         Designated officers of Mutual Savings also participate in a
nonqualified defined benefit pension plan. This nonqualified plan provides
monthly supplemental benefits to participants which will be paid out of
unsecured corporate assets, or the rabbi trust established for this plan. The
amount of the nonqualified plan benefit in the form of a ten year certain and
life annuity is determined below:


         -    an amount calculated under Mutual Savings' qualified defined
              benefit pension plan without regard to the limitations imposed by
              the Internal Revenue Code on benefit or compensation amounts and
              without regard to certain limitations on years of service; minus
         -    the pension benefit accrued in the qualified defined benefit
              pension plan.

         The following table shows the estimated annual benefits payable in ten
year certain and life annuity form for participants retiring on their normal
retirement date at age 65 with various combinations of years of service and
average annual compensation under the qualified defined benefit plan plus, for
those officers eligible to participate, the nonqualified plan. At March 31,
2000, accrued years of service for officers named in the summary compensation
table were: Mr. Crowley, Sr. - 66 years; Mr. Crowley, Jr. - 32 years; Mr. Maurer
- - - 18 years; and Mr. Anderegg - 6 years. Mr. Tietz had been covered by the prior
retirement plan of First Federal; accrued benefits under the Mutual Savings plan
were minimal.

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

(1)      Years of service in the nonqualified defined benefit pension plan begin
         at date of hire. As of December 31, 1999, Mr. Crowley, Sr. has more
         than 66 years of service with Mutual Savings. The amount of his total
         annual accrued benefit as of December 31, 1999 was approximately
         $308,000.

EMPLOYMENT AGREEMENTS

         Mutual Savings has employment agreements with Messrs. Crowley Sr. and
Jr. and intends to enter into employment agreements with its other executive
officers. The initial terms of the employment agreements will be three years.
For Messrs. Crowley, each year the agreement may be extended so that the
agreement remains for three years upon agreement of Mr. Crowley and by
affirmative action of Mutual Savings' board of directors. For the other
executives, the end of the initial three year term and on each anniversary date
thereafter, the employment term may be extended for an additional year upon
agreement of the executive and by affirmative action taken by Mutual Saving's
Board of Directors. Under the employment agreements, each executive officer will
be entitled to a base salary which is reviewed annually based upon individual
performance and Mutual Saving's financial results, as well as benefits and
perquisites, in accordance with Mutual Saving's policies.

         The employment agreements can be terminated at the election of the
executive officer or Mutual Savings at the expiration of the term, at any time
for cause, upon the occurrence of certain events specified by federal statute or
regulation, or as a result of the executive officer's retirement, disability or
death. Each employment agreement can also be voluntarily terminated without
cause by the executive officer or Mutual Savings. Each executive officer may
also terminate his employment agreement under certain circumstances following a
change in control.

         Upon termination of an executive's employment at their election at the
expiration of the term of the employment agreements, the executive is entitled
to receive unpaid compensation for the period of employment plus accrued but
unused vacation time. Upon termination of employment at the election of Mutual
Savings at the expiration of the terms, the executives are entitled to receive
the same compensation as if they had voluntarily terminated at the end of the
term as well as an amount equal to 100% of their annual base salary at the date
of termination and certain benefits for a period of twelve months thereafter.

         Upon each executive's death or retirement at age 65, the executive or
the executive's personal representative will receive his earned but unpaid base
salary and incentive compensation prorated to the end of the calendar month in
which such termination occurs and compensation for accrued but unused vacation
time. If the executive officer terminates employment voluntarily or is
terminated by Mutual Savings for cause, the executive shall not be entitled to
any compensation or benefits for any period after the date of termination.



                                      -99-
<PAGE>   102

         If during the term Mutual Savings terminates an executive officer
without cause or the employment agreement is terminated by the executive officer
for cause, the executive would be entitled to receive 100% of base salary at the
time of termination through the end of a severance period. If the termination
occurs within the initial three year term of employment, the severance period
will be through the end of the initial three year term of employment, but not
less than one year, and if the termination shall occur after the expiration of
the initial three year term, the severance period will be one year. In the case
of Messrs. Crowley, the period is extended to 12 months beyond the current term
of employment, but not more than 36 months. Also, the executive officer would
continue to receive certain insurance and other benefits until twelve months
after the end of the term of employment. Mutual Savings must also pay to each
executive officer an additional lump sum cash payment in an amount equal to the
product of Mutual Saving's annual aggregate contributions for the benefit of the
executive officer to all qualified retirement plans in the year preceding
termination and the number of years in the severance period.

         Under each employment agreement, the executive officer may also
terminate employment following a change in control of Mutual Savings, as defined
in the employment agreements under certain circumstances, including a reduction
in compensation or responsibilities. Upon any such termination as a result of a
change in control, each executive officer has a right to receive payments and
benefits as if a termination by Mutual Savings without cause had occurred.
However, under no circumstances may the aggregate amount of all severance
payments and termination benefits, computed on a present value basis, exceed an
amount which would cause the payments to be characterized as parachute payments
within the meaning of Section 280G(b)(2) of the Internal Revenue Code. That
section generally defines parachute payments to include any severance payments
and termination benefits which, on a present value basis, equal or exceed three
times the executive officer's average annual total compensation over a five-year
period immediately preceding the change in control.


OTHER COMPENSATION AGREEMENTS

         Crowley Sr. Deferred Compensation Agreement. Mutual Savings has had a
deferred compensation arrangement with Mr. Crowley, Sr. for over 20 years under
which Mutual Savings agreed to defer a portion of Mr. Crowley's compensation in
exchange for compensation payments at the later date. The exact provisions have
been modified from time to time, most recently in a 1998 agreement. To fund this
obligation, Mutual Savings purchased a life insurance policy on the life of Mr.
Crowley, Sr. The policy is now fully paid.

         Upon Mr. Crowley, Sr.'s retirement, he will receive a life income in
monthly installments, with a minimum of 240 monthly installments. The monthly
installments will be equal to the amount that would be payable to Mutual Savings
under the life insurance policy if Mutual Savings were to exercise a settlement
option under the policy for monthly life income, with a 240 month period
certain, with payments commencing as of the date of Mr. Crowley's retirement. If
Mr. Crowley were to die before retirement or receipt of 240 certain monthly
payments, the amounts otherwise payable to him will be paid in equal shares to
his two children (including Mr. Crowley, Jr.) or to their survivors.

         Under certain circumstances, Mutual Savings may elect to make a lump
sum or other type of payment to Mr. Crowley or his heirs. Those payments would
be based upon other forms of payment which may be available under the life
insurance policy.

BENEFIT PLANS

         Employee Stock Ownership Plan. This plan is a tax-qualified plan that
covers substantially all salaried employees who have at least one year of
service and have attained age 21 and will take effect at the completion of the
restructuring.

         Bank Mutual intends to lend this plan enough money to purchase 8% of
the Bank Mutual shares issued to persons other than the MHC. The plan may
purchase all or part of these shares from Bank Mutual to the extent that

                                     -100-
<PAGE>   103



shares are available after filling the subscriptions of eligible account
holders. Alternatively, the plan may purchase all or part of these shares in
private transactions or on the open market after completion of the restructuring
to the extent that shares are available for purchase on reasonable terms. We
have not determined whether that purchase would be made directly from Bank
Mutual in the offering, or after completion of the restructuring. We expect to
make that determination immediately before the expiration date for submitting
orders in the offering. For this reason, we cannot assure you that the employee
stock ownership plan will purchase shares in the offering after the
restructuring, or that such purchases will occur during any particular time
period or at any particular price.

         Although contributions to this plan will be discretionary, Mutual
intends to contribute enough money each year to make the required principal and
interest payments on the loan from Bank Mutual. It is expected that this loan
will be for a term of ten years and will call for level annual payments of
principal. It is anticipated that payments will be made quarterly and will
include interest at the prime rate. The plan will initially pledge the shares it
purchases as collateral for the loan and hold them in a suspense account.

         The plan will not distribute the pledged shares immediately. Instead,
it will release a portion of the pledged shares annually. Assuming we complete
the restructuring before September 30, 2000, if the plan repays its loan as
scheduled over a 10-year term, we expect that 5% of the shares will be released
in 2000, 10% of the shares will be released annually in 2001 through 2009, and
the remaining 5% of the shares will be released in 2010. The plan will allocate
the shares released each year among the accounts of participants in proportion
to their base salary for the year. For example, if a participant's base salary
for a year represents 1% of the total base salaries of all participants for the
year, the plan would allocate to that participant 1% of the shares released for
the year.

         Participants will direct the voting of shares allocated to their
individual accounts. Shares in the suspense account will usually be voted in a
way that mirrors the votes which participants cast for shares in their
individual accounts.

         This plan may purchase additional shares in the future, and may do so
using borrowed funds, cash dividends, periodic employer contributions or other
cash flow.

         Restoration Plan. Mutual is also implementing a "restoration plan" to
compensate selected executive officers for any benefits under the ESOP and the
Mutual Savings Bank Savings and Investment Plan which they are unable to receive
because of limitations under the Internal Revenue Code (the "Code") on
contributions and benefits. The Code limits the salary deferrals that an
employee may contribute to the Savings Plan and also restricts the amount of
tax-qualified plan benefits that can be received by plan participants.

         The restoration plan will permit eligible officers to defer
compensation which they are unable to contribute to the Savings Plan because of
the Internal Revenue Code limits. In addition, the restoration plan will provide
benefits for eligible officers based upon the allocations they would have
received in the ESOP and Savings Plan in the absence of the Code limitations.
Under the Code, only the first $170,000 of compensation may be considered in
determining benefits under tax-qualified plans (subject to annual cost-of-living
adjustments).

         For example, under the ESOP, only the first $170,000 of earnings are
considered in determining ESOP benefits. Under the restoration plan, an
executive officer would receive an amount equal to the benefit that the officer
would have received under the ESOP in the absence of the compensation limit.
Therefore, if an executive officer had total compensation of $250,000, the
officer would receive an award equal to the average allocation percentage under
the ESOP for the $80,000 of compensation in excess of the Code limit.

         Payments under the restoration plan would be made in cash. The are tax
deductible by the employer, but are included in the taxable compensation of the
officer receiving such a payment. The restoration plan would initially cover
Messrs. Crowley Sr. and Jr.

FUTURE STOCK BENEFIT PLANS

         Stock Option Plan. Bank Mutual intends to implement a stock option plan
for Mutual's directors, officers and employees after the restructuring.
Applicable regulations prohibit us from implementing this plan until six months
after the restructuring. If we implement this plan within one year after the
restructuring, applicable regulations require that we first obtain the approval
of the holders of a majority of the outstanding shares of Bank Mutual that are
not owned by the MHC. We have not decided whether we will implement this plan
before or after the one-year anniversary of the restructuring.

         We expect to adopt a stock option plan that will authorize the
Compensation Committee to grant options to purchase up to 10% of the shares
issued in the restructuring and the First Northern merger, over a period of 10
years. The Committee will decide which eligible participants will receive
options and what the terms of those options will be. However, no stock option
will permit its recipient to purchase shares at a price that is less than the
fair market value of a share on the date the option is granted, and no option
will have a term that is longer than 10 years.

         If we implement a stock option plan before the first anniversary of the
restructuring, applicable regulations will require that we observe the following
restrictions:

         -     We must limit the total number of shares that are optioned to
               outside directors to 30% of the shares authorized for the plan.

         -     We must also limit the number of options granted to any one
               outside director to 5% of the shares authorized for the plan and
               the number of shares that are optioned to any executive officer
               to 25% of the shares that are authorized for the plan.

         -     We must not permit the options to become vested at a more rapid
               rate than 20% per year beginning on the first anniversary of
               shareholder approval of the plan.

         -     We must not permit accelerated vesting for any reason other than
               death or disability.


         After the first anniversary of the restructuring, we may amend the plan
to change or remove these restrictions. If we adopt a stock option plan within
one year after the restructuring, we expect to later amend the plan, subject to
shareholder approval, to remove these restrictions and to provide for
accelerated vesting in cases of retirement and change of control. We expect that
any other amendment to this plan, whether adopted before or after the first
anniversary of the plan's initial effective date will be subject to shareholder
approval if it would change the class of people eligible to receive benefits,
change the price they must pay for stock which they acquire under the plan, or
increase the number of shares available under the plan or increase the maximum
amount of stock that may be acquired by any one person under the plan.

         We may obtain the shares needed for this plan by issuing additional
shares or through stock repurchases. Because we cannot issue new shares that
would reduce the MHC's ownership position to less than a majority of Bank
Mutual's outstanding shares, we expect to obtain most or all of the shares for
this plan through stock repurchases, in which case there would not be dilution
to then-existing shareholders.

         We expect the stock option plan will permit the Committee to grant
either incentive stock options that qualify for special federal income tax
treatment or non-qualified stock options that do not qualify for special
treatment. Incentive stock options may be granted only to employees and will not
create federal income tax consequences when they are granted. If they are
exercised during employment or within three months after termination of
employment, the exercise will not create federal income tax consequences either.
When the shares acquired on exercise of an incentive stock option are resold,
the seller must pay federal income taxes on the amount by which the sales price
exceeds the purchase price. This amount will be taxed at capital gains rates if
the sale occurs at least two years after the option was granted and at least one
year after the option was exercised. Otherwise, it is taxed as ordinary income.


                                     -102-
<PAGE>   105



         Non-qualified stock options may be granted to either employees or
non-employees such as directors, consultants and other service providers.
Incentive stock options that are exercised more than three months after
termination of employment are treated as non-qualified stock options.
Non-qualified stock options will not create federal income tax consequences when
they are granted. When they are exercised, federal income taxes must be paid on
the amount by which the fair market value of the shares acquired by exercising
the option exceeds the exercise price. When the shares acquired on exercise of
anon-qualified stock option are resold, the seller must pay federal income taxes
on the amount by which the sales price exceeds the purchase price plus the
amount included in ordinary income when the option was exercised. This amount
will be taxed at capital gains rates, which will vary depending upon the time
that has elapsed since the exercise of the option.

         When a non-qualified stock option is exercised, Mutual may be allowed a
federal income tax deduction for the same amount that the option holder includes
in his or her ordinary income. When an incentive stock option is exercised,
there is no tax deduction unless the shares acquired are resold sooner than two
years after the option was granted or one year after the option was exercised.

         Management Recognition Plan. We intend to implement a management
recognition plan for our directors and officers after the restructuring.
Applicable regulations prohibit us from implementing this plan until six months
after the restructuring. If we implement this plan within one year after the
restructuring, the regulations require that we first obtain the approval of the
holders of a majority of the outstanding shares of Bank Mutual that are not held
by the MHC. We have not decided whether we will implement this plan before or
after the one-year anniversary of the restructuring. We expect to adopt a
management recognition plan that will authorize the Compensation Committee to
make restricted stock awards of up to 4% of the shares issued to investors other
than the MHC. The Compensation Committee will decide which directors and
officers will receive restricted stock and what the terms of those awards will
be. If we implement a management recognition plan before the first anniversary
of the restructuring, applicable regulations will require that we observe the
following restrictions:

         -     We must limit the total number of shares that are awarded to
               outside directors to 30% of the shares authorized for the plan.


         -     We must also limit the number of shares that are awarded to any
               one outside director to 5% of the shares authorized for the plan
               and the number of shares that are awarded to any executive
               officer to 25% of the shares that are authorized for the plan.

         -     We must not permit the awards to become vested at a more rapid
               rate than 20% per year beginning on the first anniversary of
               shareholder approval of the plan.

         -     We must not permit accelerated vesting for any reason other than
               death or disability.

         After the first anniversary of the restructuring, we may amend the plan
to change or remove these restrictions. If we adopt a management recognition
plan within one year after the restructuring, we expect to amend the plan later,
subject to shareholder approval, to remove these restrictions and to provide for
accelerated vesting in cases of retirement and change of control. We expect that
any other amendment to this plan, whether adopted before or after the first
anniversary of the plan's initial effective date, will be subject to shareholder
approval if it would change the class of people eligible to receive benefits,
change the price they must pay for stock which they acquire under the plan, or
increase the number of shares available under the plan or increase the maximum
amount of stock that may be acquired by any one person under the plan.

         We may obtain the shares needed for this plan by issuing additional
shares or through stock repurchases. Because we cannot issue new shares that
would reduce the MHC's ownership position to less than a majority of Bank
Mutual's outstanding shares, we expect to obtain most or all of the shares for
this plan through stock repurchases, to minimize dilution. Restricted stock
awards under this plan may feature employment restrictions that



                                     -103-
<PAGE>   106

require continued employment for a period of time for the award to be vested.
They may feature restrictions that require the achievement of specified
corporate or individual performance goals for the award to be vested. Or, they
may feature a combination of employment and performance restrictions. Awards are
not vested unless the specified employment restrictions and performance goals
are met. However, pending vesting, the award recipient may have voting and
dividend rights. When an award becomes vested, the recipient must include the
current fair market value of the vested shares in his income for federal income
tax purposes. Bank Mutual and Mutual Savings may be allowed a federal income tax
deduction in the same amount. Depending on the nature of the restrictions
attached to the restricted stock award, Bank Mutual and Mutual Savings may have
to recognize a compensation expense for accounting purposes ratably over the
vesting period or in a single charge when the performance conditions are
satisfied.

LIMITATIONS ON FEDERAL TAX DEDUCTIONS FOR EXECUTIVE OFFICER COMPENSATION

         As a private entity, Mutual Savings has been subject to federal tax
rules which permit it to claim a federal income tax deduction for a reasonable
allowance for salaries or other compensation for personal services actually
rendered. Following the restructuring, federal tax laws may limit this deduction
to $1 million each tax year for each executive officer named in the summary
compensation table in Bank Mutual's proxy statement for that year. This limit
will not apply to non-taxable compensation under various broad-based retirement
and fringe benefit plans, to compensation that is "qualified performance-based
compensation" under applicable law or to compensation that is paid in
satisfaction of commitments that arose before the restructuring. Bank Mutual and
Mutual Savings expect that the Compensation Committee will take this deduction
limitation into account with other relevant factors in establishing the
compensation levels of their executive officers and in setting the terms of
compensation programs. However, there is no assurance that all compensation paid
to our executive officers will be deductible for federal income tax purposes. To
the extent that compensation paid to any executive officer is not deductible,
the net after-tax cost of providing the compensation will be higher and the net
after-tax earnings of Bank Mutual and Mutual Savings will be reduced.

CERTAIN TRANSACTIONS WITH MEMBERS OF OUR BOARD OF DIRECTORS AND EXECUTIVE
OFFICERS

         Mutual Savings has had, and expects to continue to have, regular
business dealings with its officers and directors, as well as their associates
in firms which they serve in various capacities. Consistent with applicable law,
Mutual's policy is that transactions with its directors and executive officers
be on terms that are no more beneficial to the director or executive officer
than Mutual Savings would provide to unaffiliated third parties. Directors and
executive officers, and their associates, regularly deposit funds with Mutual
Savings; the deposits are on terms and conditions offered to other depositors.

         To help prevent any inadvertent violations of its policy, Mutual
Savings discourages lending transactions between Mutual Savings and its
insiders, but loans are occasionally made. Certain of the directors and
executive officers have been indebted to Mutual Savings for loans made in the
ordinary course of business. All such loans have been on substantially the same
terms, including interest rates and collateral, as those prevailing at the time
for comparable transactions with other persons. These loans do not involve more
than the normal risk of collectability or present other unfavorable futures.

PROPOSED PURCHASES OF COMMON STOCK BY MANAGEMENT

         The following table presents, for each member of Mutual Savings' board
of directors and executive officers, the amount of stock they wish to purchase
in the offering. We have assumed that a sufficient number of shares will be
available to satisfy their subscriptions. The amounts include shares that may be
purchased through individual retirement accounts and by associates of members of
our Board of Directors and executive officers.


                                     -104-
<PAGE>   107

         The table does not reflect the number of shares which management may
acquire under the employee stock ownership plan or any non tax-qualified
stock-based benefit plan, nor as a result of issuance of Bank Mutual common
stock in the First Northern merger. Mutual is not aware of any First Northern
stock ownership by its officers and directors.

         None of the members of our board of directors or executive officers
expect to purchase more than    % of Bank Mutual's common stock. Collectively,
the current members of the board of directors and executive officers expect to
purchase a total of          shares, or    % of shares sold in the offering,
assuming the sale of 5,906,014 shares of common stock.

         In addition, four of the current directors of First Northern will
become directors of Bank Mutual. The six First Northern directors currently own
a total of approximately 1.0 million outstanding shares of First Northern common
stock. Only four out of the six persons will become directors of Bank Mutual,
and we cannot assure that all of their current First Northern shares will be
converted into Bank Mutual shares in the First Northern merger. However, we
expect that the four persons chosen as directors will elect to receive at least
some shares of Bank Mutual common stock in the First Northern merger, thus
increasing management ownership going forward.


                                   REGULATION

         Set forth below is a brief description of certain laws and regulations
which relate to the regulation of Mutual Savings, before and after the
restructuring, and Bank Mutual, the MHC and First Northern Savings thereafter.
The description does not purport to be complete and is qualified in its entirety
by reference to the applicable laws and regulations.

GENERAL

         Mutual Savings is a Wisconsin chartered mutual savings bank, and its
deposit accounts are insured up to applicable limits by the Federal Deposit
Insurance Corporation under the Savings Association Insurance Fund. Mutual
Savings currently is subject to extensive regulation, examination and
supervision by the Division of Savings Institutions of the Wisconsin Department
of Financial Institutions (the "Division") as its chartering agency, and by the
FDIC as the deposit insurer. Mutual Savings must file reports with the Division
and the FDIC concerning its activities and financial condition, and it must
obtain regulatory approval prior to entering into certain transactions, such as
mergers with, or acquisitions of, other depository institutions and opening or
acquiring branch offices.

         The Division and the FDIC currently conduct periodic examinations to
assess Mutual Savings' compliance with various regulatory requirements. This
regulation and supervision establishes a comprehensive framework of


                                     -105-

<PAGE>   108


activities in which a savings bank can engage and is intended primarily for the
protection of the deposit insurance fund and depositors. The regulatory
structure also gives the regulatory authorities extensive discretion in
connection with their supervisory and enforcement activities and examination
policies, including policies with respect to the classification of assets and
the establishment of adequate loan loss reserves for regulatory purposes.

         Following the restructuring, in which Mutual Savings and First Northern
Savings will convert to federally-chartered stock savings banks, and the Office
of Thrift Supervision (OTS) will become the primary regulator of both banks. The
FDIC will remain responsible for supervisory and enforcement activities and
examination policies with respect to the deposit insurance fund. Following the
restructuring, the Division will no longer be responsible for regulation or
supervision of Mutual Savings or First Northern Savings.

         Upon completion of the restructuring, the MHC will become a federal
mutual holding company within the meaning of Section 10(o) of the Home Owners'
Loan Act. As such, the MHC will be required to register with and be subject to
OTS examination and supervision as well as certain reporting requirements.
Following the restructuring, Bank Mutual, as a federal stock corporation in a
mutual holding company structure, will be deemed a federal stock holding company
within the meaning of Section 10(o) of the Home Owners' Loan Act. Bank Mutual
will be required to register and file reports with the OTS and will be subject
to regulation and examination by the OTS. Bank Mutual will be required to file
certain reports with, and otherwise comply with, the rules and regulations of
the Securities and Exchange Commission under the federal securities laws.

         Any change in such laws and regulations, whether by the OTS, the FDIC,
the SEC, or through legislation, could have a material adverse impact on Mutual
Savings, Bank Mutual, and the MHC and their operations and shareholders.

         Certain of the laws and regulations applicable to Mutual Savings, Bank
Mutual, the MHC and First Northern Savings are summarized below or elsewhere in
this prospectus. These summaries do not purport to be complete and are qualified
in their entirety by reference to such laws and regulations.

MUTUAL SAVINGS
STATE REGULATION PRIOR TO RESTRUCTURING

         Activity Powers. Mutual Savings derives its lending, investment and
other activity powers primarily from the applicable provisions of Chapter 214 of
the Wisconsin Statutes and its related regulations. Under these laws and
regulations, savings banks, including Mutual Savings, generally may invest in:

           -   real estate mortgages;

           -   consumer and commercial loans;

           -   specific types of debt securities, including certain corporate
               debt securities and obligations of federal, state and local
               governments and agencies;

           -   certain types of corporate equity securities; and

           -   certain other assets.

A savings bank may also exercise trust powers upon approval of the Division.
Wisconsin savings banks may also exercise any power or offer any financially
related product or service that any other provider of financial products or
services may undertake in Wisconsin, unless the Division determines otherwise.
The exercise of these lending, investment and activity powers are limited by
federal law and the related regulations. See " - Federal Regulation Prior to
Restructuring - Activity Restrictions on State-chartered Banks" below.


                                      -106-
<PAGE>   109


         Loans-to-One-Borrower Limitations. With certain specified exceptions, a
Wisconsin chartered savings bank may not make loans or extend credit to a single
borrower and to entities related to the borrower in an aggregate amount that
would exceed 15% of the bank's capital funds. A savings bank may lend an
additional 10% of the bank's capital funds if secured by collateral meeting the
requirements of Wisconsin laws and regulations. Mutual Savings currently
complies with applicable loans-to-one borrower limitations.

         Minimum Capital Requirements. Under regulations of the Division,
Wisconsin savings banks must at all times maintain a net worth ratio in an
amount not less than 6.0%. For purposes of the regulation, the term "net worth
ratio" means the ratio, expressed as a percentage, the numerator of which is the
result of subtracting the savings bank's liabilities from its assets and adding
to that number unallocated, general loan loss reserves, but not loss reserves
for specific, identified losses, and the denominator of which is the savings
bank's assets. As of March 31, 2000, Mutual Savings' net worth ratio was 9.81%.

         Examination and Enforcement. The Division may examine Mutual Savings
whenever it deems an examination advisable. The Division examines Mutual Savings
at least every 18 months. The Division may remove from a savings bank any
employee, agent or person affiliated with the savings bank if the Division finds
that the person has directly or indirectly violated any state or federal law,
regulation, rule or order regarding the operations of the savings bank or has
breached fiduciary or professional responsibilities to the savings bank.

MUTUAL SAVINGS
FEDERAL REGULATION PRIOR TO RESTRUCTURING

         Capital Requirements. FDIC regulations require savings banks, such as
Mutual Savings, to maintain minimum levels of capital. The FDIC regulations
define two tiers, or classes, of capital.

         Tier 1 capital is comprised of the sum of common shareholders' equity
(excluding the net unrealized appreciation or depreciation, net of tax, from
available-for-sale securities), non-cumulative perpetual preferred stock, any
related surplus, and minority interests in consolidated subsidiaries, minus all
intangible assets (other than qualifying servicing rights), and any net
unrealized loss on marketable equity securities.

         The components of Tier 2 capital currently include cumulative perpetual
preferred stock, certain perpetual preferred stock for which the dividend rate
may be reset periodically, mandatory convertible securities, subordinated debt,
intermediate preferred stock and allowance for possible loan losses. Allowance
for possible loan losses includible in Tier 2 capital is limited to a maximum of
1.25% of risk-weighted assets. Overall, the amount of Tier 2 capital that may be
included in total capital cannot exceed 100% of Tier 1 capital.

         The FDIC regulations establish a minimum leverage capital requirement
for banks in the strongest financial and managerial condition, with a rating of
1 (the highest examination rating of the FDIC for savings banks) under the
Uniform Financial Institutions Rating System, and that are not experiencing or
anticipating significant growth, of not less than a ratio of 3.0% of Tier 1
capital to total assets. For all other savings banks, the minimum leverage
capital requirement is 4.0%, unless a higher leverage capital ratio is warranted
by the particular circumstances or risk profile of the depository institution.

         The FDIC regulations also require that savings banks meet a risk-based
capital standard. The risk-based capital standard requires the maintenance of a
ratio of total capital (which is defined as the sum of Tier 1 capital and Tier 2
capital) to risk-weighted assets of at least 8% and a ratio of Tier 1 capital to
risk-weighted assets of at least 4%. In determining the amount of risk-weighted
assets, all assets, plus certain off balance sheet items, are multiplied by a
risk- weight of 0% to 100%, based on the risks the FDIC believes are inherent in
the type of asset or item.


                                     -107-
<PAGE>   110


         The federal banking agencies, including the FDIC, have also adopted
regulations to require an assessment of an institution's exposure to declines in
the economic value of a bank's capital due to changes in interest rates when
assessing the bank's capital adequacy. Under such a risk assessment, examiners
will evaluate a bank's capital for interest rate risk on a case-by-case basis,
with consideration of both quantitative and qualitative factors. According to
the agencies, applicable considerations include the quality of the bank's
interest rate risk management process, the o overall financial condition of the
bank and the level of other risks at the bank for which capital is needed.
Institutions with significant interest rate risk may be required to hold
additional capital. The agencies have also issued a joint policy statement
providing guidance on interest rate risk management, including a discussion of
the critical factors affecting the agencies' evaluation of interest rate risk in
connection with capital adequacy.

         On March 31, 2000 Mutual Savings exceeded the minimum capital adequacy
requirements; see "Capitalization."

         Activity Restrictions on State-chartered Banks. Section 24 of the
Federal Deposit Insurance Act, as amended (FDIA), which was added by the Federal
Deposit Insurance Corporation Improvement Act of 1991 (FDICIA), generally limits
the activities and investments of state-chartered FDIC insured banks and their
subsidiaries to those permissible for federally chartered national banks and
their subsidiaries, unless such activities and investments are specifically
exempted by Section 24 or consented to by the FDIC.

         Regulations promulgated by the FDIC under Section 24 allow
state-chartered savings banks to engage in certain activities upon notice to the
FDIC, if such activities are conducted in a majority-owned subsidiary and meet
certain other regulatory conditions. Pursuant to these regulations, Mutual
Savings currently owns, through a subsidiary, four lots adjacent to its
headquarters in Brown Deer, Wisconsin and 318 acres of undeveloped land in
Oconomowoc, Wisconsin.

         Before making a new investment or engaging in a new activity not
permissible for a national bank or otherwise permissible under Section 24 of the
FDIC regulations thereunder, an insured bank must seek approval from the FDIC to
make such investment or engage in such activity. The FDIC will not approve the
activity unless the bank meets its minimum capital requirements and the FDIC
determines that the activity does not present a significant risk to the FDIC
insurance funds.

         Enforcement. The FDIC has extensive enforcement authority over insured
state savings banks, including Mutual Savings. This enforcement authority
includes, among other things, the ability to assess civil money penalties, to
issue cease and desist orders and to remove directors and officers. In general,
these enforcement actions may be initiated in response to violations of laws and
regulations and to unsafe or unsound practices.

         The FDIC is required, with certain exceptions, to appoint a receiver or
conservator for an insured state savings bank if that bank is "critically
undercapitalized." For this purpose, "critically undercapitalized" means having
a ratio of tangible capital to total assets of less than 2%. The FDIC may also
appoint a conservator or receiver for a state bank on the basis of the
institution's financial condition or upon the occurrence of certain events,
including:

         -     insolvency, whereby the assets of the bank are less than its
               liabilities to depositors and others;

         -     substantial dissipation of assets or earnings through violations
               of law or unsafe or unsound practices;

         -     existence of an unsafe or unsound condition to transact business;

         -     likelihood that the bank will be unable to meet the demands of
               its depositors or to pay its obligations in the normal course of
               business; and

                                     -108-
<PAGE>   111


         -     insufficient capital, or the incurring or likely incurring of
               losses that will deplete substantially all of the institution's
               capital with no reasonable prospect of replenishment of capital
               without federal assistance.

         Deposit Insurance. The deposit accounts held by Mutual Savings are
insured by the SAIF to a maximum of $100,000 as permitted by law. Insurance on
deposits may be terminated by the FDIC if it finds the Mutual Savings has
engaged in unsafe or unsound practices, is in an unsafe or unsound condition to
continue operations or has violated any applicable law, regulation, rule, order
or condition imposed by the FDIC or the OTS as Mutual Savings' primary
regulator.

         Pursuant to FDICIA, the FDIC established a system for setting deposit
insurance premiums based upon the risks a particular bank or savings association
posed to its deposit insurance funds. Under the risk-based deposit insurance
assessment system, the FDIC assigns an institution to one of three capital
categories based on the institution's financial information, as of the reporting
period ending six months before the assessment period. The three capital
categories are (i) well capitalized, (ii) adequately capitalized and (iii)
undercapitalized. The FDIC also assigns an institution to one of three
supervisory subcategories within each capital group. With respect to the capital
ratios, institutions are classified as well capitalized, adequately capitalized
or undercapitalized using ratios that are substantially similar to the prompt
corrective action capital ratios discussed below. The FDIC also assigns an
institution to a supervisory subgroup based on a supervisory evaluation provided
to the FDIC by the institution's primary federal regulator and information that
the FDIC determines to be relevant to the institution's financial condition and
the risk posed to the deposit insurance funds (which may include, if applicable,
information provided by the institution's state supervisor).

         An institution's assessment rate depends on the capital category and
supervisory category to which it is assigned. Under the final risk-based
assessment system, there are nine assessment risk classifications (i.e.,
combinations of capital groups and supervisory subgroups) to which different
assessment rates are applied. Assessment rates for deposit insurance currently
range from 0 basis points to 27 basis points. The capital and supervisory
subgroup to which an institution is assigned by the FDIC is confidential and may
not be disclosed. A bank's rate of deposit insurance assessments will depend
upon the category and subcategory to which the bank is assigned by the FDIC. Any
increase in insurance assessments could have an adverse effect on the earnings
of insured institutions, including Mutual Savings.

         Under the FDIA, the FDIC may terminate the insurance of an
institution's deposits upon a finding that the institution has engaged in unsafe
or unsound practices, is in an unsafe or unsound condition to continue
operations or has violated any applicable law, regulation, rule, order or
condition imposed by the FDIC. The management of Mutual Savings does not know of
any practice, condition, or violation that might lead to termination of its
deposit insurance.

         Transactions with Affiliates. Transactions between an insured state
savings bank, such as Mutual Savings, and any of its affiliates are governed by
Sections 23A and 23B of the Federal Reserve Act. An affiliate of a bank is any
company or entity that controls, is controlled by or is under common control
with the bank. Currently, a subsidiary of a bank that is not also a depository
institution is not treated as an affiliate of the bank for the purposes of
Sections 23A and 23B; however, the Federal Reserve Board has proposed treating
any subsidiary of a bank that is engaged in activities not permissible for bank
holding companies under the Bank Holding Company Act of 1956 ("BHCA"), as an
affiliate for purposes of Section 23A and 23B. Sections 23A and 23B limit the
extent to which the bank or its subsidiaries may engage in "covered
transactions" with any one affiliate to an amount equal to 10% of such bank's
capital stock and surplus, and limit all such transactions with all affiliates
to an amount equal to 20% of such capital stock and surplus. The statutory
sections also require that all such transactions be on terms that are consistent
with safe and sound banking practices. The term "covered transaction" includes
the making of loans, purchase of assets, issuance of guarantees and other
similar types of transactions. Further, most loans by a bank to any of its
affiliates must be secured by collateral in amounts ranging from 100 to 130
percent of the loan amounts.


                                     -109-
<PAGE>   112



In addition, any covered transaction by a bank with an affiliate and any
purchase of assets or services by a bank from an affiliate must be on terms that
are substantially the same, or at least as favorable, to the bank as those that
would be provided to a non-affiliate.

         Prohibitions Against Tying Arrangements. Banks are subject to the
prohibitions of 12 U.S.C. Section 1972 on certain tying arrangements. A
depository institution is prohibited, subject to certain exceptions, from
extending credit to or offering any other service, or fixing or varying the
consideration for such extension of credit or service, on the condition that the
customer obtain some additional service from the institution or certain of its
affiliates or not obtain services of a competitor of the institution.

         Uniform Real Estate Lending Standards. Pursuant to FDICIA, the federal
banking agencies adopted uniform regulations prescribing standards for
extensions of credit that are secured by liens on interests in real estate or
made for the purpose of financing the construction of a building or other
improvements to real estate. Under the joint regulations adopted by the federal
banking agencies, all insured depository institutions must adopt and maintain
written policies that establish appropriate limits and standards for extensions
of credit that are secured by liens or interests in real estate or are made for
the purpose of financing permanent improvements to real estate. These policies
must establish loan portfolio diversification standards, prudent underwriting
standards (including loan-to-value limits) that are clear and measurable, loan
administration procedures, and documentation, approval and reporting
requirements. The real estate lending policies must reflect consideration of the
Interagency Guidelines for Real Estate Lending Policies that have been adopted
by the federal bank regulators.

         The Interagency Guidelines, among other things, require a depository
institution to establish internal loan-to-value limits for real estate loans
that are not in excess of the following supervisory limits:

         -     for loans secured by raw land, the supervisory loan-to-value
               limit is 65% of the value of the collateral;

         -     for land development loans (i.e., loans for the purpose of
               improving unimproved property prior to the erection of
               structures), the supervisory limit is 75%;

         -     for loans for the construction of commercial, multi-family or
               other non-residential property, the supervisory limit is 80%;

         -     for loans for the construction of one- to four-family properties,
               the supervisory limit is 85%; and

         -     for loans secured by other improved property (e.g., farmland,
               completed commercial property and other income-producing
               property, including non-owner occupied, one- to four-family
               property), the limit is 85%.

Although no supervisory loan-to-value limit has been established for
owner-occupied, one to four-family and home equity loans, the Interagency
Guidelines state that for any such loan with a loan-to-value ratio that equals
or exceeds 90% at origination, an institution should require appropriate credit
enhancement in the form of either mortgage insurance or readily marketable
collateral.

         Community Reinvestment Act. Under the Community Reinvestment Act (CRA),
any insured depository institution, including Mutual Savings, has a continuing
and affirmative obligation consistent with its safe and sound operation to help
meet the credit needs of its entire community, including low and moderate income
neighborhoods. The CRA does not establish specific lending requirements or
programs for financial institutions nor does it limit an institution's
discretion to develop the types of products and services that it believes are
best suited to its particular community. The CRA requires the FDIC, in
connection with its examination of a savings bank, to assess the depository
institution's record of meeting the credit needs of its community and to take
such record into account in


                                      -110-
<PAGE>   113

its evaluation of certain applications by such institution, including
applications for additional branches and acquisitions.

         Among other things, current CRA regulations replace the prior
process-based assessment factors with a new evaluation system that would rate an
institution based on its actual performance in meeting community needs. In
particular, the new evaluation system focuses on three tests:

         -     a lending test, to evaluate the institution's record of making
               loans in its service areas;

         -     an investment test, to evaluate the institution's record of
               investing in community development projects, affordable housing,
               and programs benefitting low or moderate income individuals and
               businesses; and

         -     a service test, to evaluate the institution's delivery of
               services through its branches, ATMs and other offices.

         The CRA requires the FDIC to provide a written evaluation of an
institution's CRA performance utilizing a four-tiered descriptive rating system
and requires public disclosure of an institution's CRA rating. Mutual Savings
received a "satisfactory" overall rating in its most recent CRA examination.

         Safety and Soundness Standards. Pursuant to the requirements of FDICIA,
as amended by the Riegle Community Development and Regulatory Improvement Act of
1994, each federal banking agency, including the FDIC, has adopted guidelines
establishing general standards relating to internal controls, information and
internal audit systems, loan documentation, credit underwriting, interest rate
exposure, asset growth, asset quality, earnings and compensation, fees and
benefits. In general, the guidelines require, among other things, appropriate
systems and practices to identify and manage the risks and exposures specified
in the guidelines. The guidelines prohibit excessive compensation as an unsafe
and unsound practice and describe compensation as excessive when the amounts
paid are unreasonable or disproportionate to the services performed by an
executive officer, employee, director, or principal shareholder.

         In addition, the FDIC adopted regulations to require a bank that is
given notice by the FDIC that it is not satisfying any of such safety and
soundness standards to submit a compliance plan to the FDIC. If, after being so
notified, a bank fails to submit an acceptable compliance plan or fails in any
material respect to implement an accepted compliance plan, the FDIC may issue an
order directing corrective and other actions of the types to which a
significantly undercapitalized institution is subject under the "prompt
corrective action" provisions of FDICIA. If a bank fails to comply with such an
order, the FDIC may seek to enforce such an order in judicial proceedings and to
impose civil monetary penalties.

         Prompt Corrective Action. FDICIA also established a system of prompt
corrective action to resolve the problems of undercapitalized institutions. The
FDIC, as well as the other federal banking regulators, adopted regulations
governing the supervisory actions that may be taken against undercapitalized
institutions. The regulations establish five categories, consisting of "well
capitalized," "adequately capitalized," "undercapitalized," "significantly
undercapitalized" and "critically undercapitalized." The FDIC's regulations
define the five capital categories as follows: Generally, an institution will be
treated as "well capitalized" if its ratio of total capital to risk-weighted
assets is at least 10%, its ratio of Tier 1 capital to risk-weighted assets is
at least 6%, its ratio of Tier 1 capital to total assets is at least 5%, and it
is not subject to any order or directive by the FDIC to meet a specific capital
level. An institution will be treated as "adequately capitalized" if its ratio
of total capital to risk-weighted assets is at least 8%, its ratio of Tier 1
capital to risk-weighted assets is at least 4%, and its ratio of Tier 1 capital
to total assets is at least 4% (3% if the bank receives the highest rating under
the Uniform Financial Institutions Rating System) and it is not a
well-capitalized institution. An institution that has total risk-based capital
of less than 8%, Tier 1 risk-based-capital of less than 4% or a leverage ratio
that is less than 4% (or less than 3% if the institution is


                                     -111-

<PAGE>   114

rated a composite "1" under the Uniform Financial Institutions Rating System)
would be considered to be "undercapitalized." An institution that has total
risk-based capital of less than 6%, Tier 1 capital of less than 3% or a leverage
ratio that is less than 3% would be considered to be "significantly
undercapitalized," and an institution that has a tangible capital to assets
ratio equal to or less than 2% would be deemed to be "critically
undercapitalized."

         The severity of the action authorized or required to be taken under the
prompt corrective action regulations increases as a bank's capital decreases
within the three undercapitalized categories. All banks are prohibited from
paying dividends or other capital distributions or paying management fees to any
controlling person if, following such distribution, the bank would be
undercapitalized. The FDIC is required to monitor closely the condition of an
undercapitalized bank and to restrict the growth of its assets. An
undercapitalized bank is required to file a capital restoration plan within 45
days of the date the bank receives notice that it is within any of the three
undercapitalized categories, and the plan must be guaranteed by any parent
holding company. The aggregate liability of a parent holding company is limited
to the lesser of:

         -     an amount equal to five percent of the bank's total assets at the
               time it became "undercapitalized"; and

         -     the amount that is necessary (or would have been necessary) to
               bring the bank into compliance with all capital standards
               applicable with respect to such bank as of the time it fails to
               comply with the plan.

If a bank fails to submit an acceptable plan, it is treated as if it were
"significantly undercapitalized." Banks that are significantly or critically
undercapitalized are subject to a wider range of regulatory requirements and
restrictions.

         The FDIC has a broad range of grounds under which it may appoint a
receiver or conservator for an insured depositary bank. If one or more grounds
exist for appointing a conservator or receiver for a bank, the FDIC may require
the bank to issue additional debt or stock, sell assets, be acquired by a
depository bank holding company or combine with another depository bank. Under
FDICIA, the FDIC is required to appoint a receiver or a conservator for a
critically undercapitalized bank within 90 days after the bank becomes
critically undercapitalized or to take such other action that would better
achieve the purposes of the prompt corrective action provisions. Such
alternative action can be renewed for successive 90-day periods. However, if the
bank continues to be critically undercapitalized on average during the quarter
that begins 270 days after it first became critically undercapitalized, a
receiver must be appointed, unless the FDIC makes certain findings that the bank
is viable.

         Loans to a Bank's Insiders. A bank's loans to its executive officers,
directors, any owner of 10% or more of its stock (each, an insider) and any of
certain entities affiliated with any such person (an insider's related interest)
are subject to the conditions and limitations imposed by Section 22(h) of the
Federal Reserve Act and the Federal Reserve Board's Regulation O thereunder.
Under these restrictions, the aggregate amount of the loans to any insider and
the insider's related interests may not exceed the loans-to-one-borrower limit
applicable to national banks, which is comparable to the loans-to-one-borrower
limit applicable to Mutual Savings' loans. See "-- Loans-to-One Borrower
Limitations." All loans by a bank to all insiders and insiders' related
interests in the aggregate may not exceed the bank's unimpaired capital and
unimpaired surplus. With certain exceptions, loans to an executive officer,
other than loans for the education of the officer's children and certain loans
secured by the officer's residence, may not exceed the lesser of $100,000 or the
greater of $25,000 or 2.5% of the bank's capital and unimpaired surplus.
Regulation O also requires that any proposed loan to an insider or a related
interest of that insider be approved in advance by a majority of the board of
directors of the bank, with any interested director not participating in the
voting, if such loan, when aggregated with any existing loans to that insider
and the insider's related interests, would exceed either $500,000 or the greater
of $25,000 or 5% of the bank's unimpaired capital and surplus. Generally, such
loans must be made on substantially the same terms as, and follow credit
underwriting procedures that are not less stringent than, those that are
prevailing at the time for comparable transactions with other persons.


                                     -112-
<PAGE>   115

         An exception is made for extensions of credit made pursuant to a
benefit or compensation plan of a bank that is widely available to employees of
the bank and that does not give any preference to insiders of the bank over
other employees of the bank.

MUTUAL SAVINGS AND FIRST NORTHERN SAVINGS
FEDERAL REGULATION FOLLOWING RESTRUCTURING

         General. As federally chartered, SAIF-insured savings banks, Mutual
Savings and First Northern Savings (together, the "Banks") will be subject to
extensive regulation by the OTS and the FDIC. Lending activities and other
investments must comply with federal statutory and regulatory requirements. This
federal regulation and supervision establishes a comprehensive framework of
activities in which an institution can engage and is intended primarily for the
protection of the SAIF of the FDIC and depositors. This regulatory structure
gives the regulatory authorities extensive discretion in connection with their
supervisory and enforcement activities and examination policies, including
policies regarding the classification of assets and the establishment of
adequate loan loss reserves.

         The OTS will regularly examine the Banks and prepare a report on its
examination findings to their boards of directors. The Banks' relationship with
its depositors and borrowers will also be regulated by federal law, especially
in such matters as the ownership of savings accounts and the form and content of
the Banks' mortgage documents.

         The Banks will have to file reports with the OTS and the FDIC
concerning its activities and financial condition, and will have to obtain
regulatory approvals prior to entering into transactions such as mergers with or
acquisitions of other financial institutions. Any change in such regulations,
whether by the OTS, the FDIC or the United States Congress, could have a
material adverse impact on the Banks and their operations.

         Regulation of the Banks following the restructuring will be comparable
in many respects to the regulation of Mutual Savings prior to the restructuring
described above with several key differences. Because of their conversion to a
federal savings bank charter, the Banks will no longer be subject to the
regulation or supervision of the Division. In addition, because of this charter
conversion, the OTS will become their primary federal regulator. Set forth below
are several material differences in the federal regulation and supervision of
the Banks after the restructuring as compared to its regulation before the
restructuring as described above.

         Regulatory Capital Requirements. OTS capital regulations require
savings institutions to meet three capital standards. The standards are tangible
capital equal to 1.5% of adjusted total assets, core capital equal to at least
3% of total adjusted assets, and risk-based capital equal to 8% of total
risk-weighted assets. Mutual Savings' pro forma capital ratios are set forth
under "Regulatory Capital Compliance."

         Tangible capital is defined as core capital less all intangible assets
and mortgage servicing rights. Core capital is defined as common shareholders'
equity, noncumulative perpetual preferred stock and minority interests in the
equity accounts of consolidated subsidiaries, nonwithdrawable accounts and
pledged deposits of mutual savings associations and qualifying supervisory
goodwill, less nonqualifying intangible assets and mortgage servicing rights.

         The risk-based capital standard for savings institutions requires the
maintenance of total risk-based capital of 8% of risk-weighted assets.
Risk-based capital is comprised of core and supplementary capital. The
components of supplementary capital include, among other items, cumulative
perpetual preferred stock, perpetual subordinated debt, mandatory convertible
subordinated debt, intermediate-term preferred stock, and the portion of the
allowance for loan losses not designated for specific loan losses. The portion
of the allowance for loan and lease losses includible in supplementary capital
is limited to a maximum of 1.25% of risk-weighted assets. Overall,


                                     -113-

<PAGE>   116

supplementary capital is limited to 100% of core capital. A savings association
must calculate its risk-weighted assets by multiplying each asset and
off-balance sheet item by various risk factors as determined by the OTS, which
range from 0% for cash to 100% for delinquent loans, property acquired through
foreclosure, commercial loans, and other assets.

         OTS rules require a deduction from capital for institutions which have
unacceptable levels of interest rate risk. The OTS calculates the sensitivity of
an institution's net portfolio value based on data submitted by the institution
in a schedule to its quarterly Thrift Financial Report and using the interest
rate risk measurement model adopted by the OTS. The amount of the interest rate
risk component, if any, is deducted from an institution's total capital in order
to determine if it meets its risk-based capital requirement. Federal savings
institutions with less than $300 million in assets and a risk-based capital
ratio above 12% are exempt from filing the interest rate risk schedule. However,
the OTS may require any exempt institution to file such schedule on a quarterly
basis and may be subject to an additional capital requirement based on its level
of interest rate risk as compared to its peers.

         Dividend and Other Capital Distribution Limitations. The OTS imposes
various restrictions or requirements on the ability of savings institutions to
make capital distributions, including dividend payments.

         The OTS rules regarding capital distributions, which were substantially
updated effective April 1, 1999, define the term "capital distribution" as a
distribution of cash or other property to a savings association's owners, made
on account of their ownership. The definition specifically excludes dividends
consisting only of a savings association's shares or rights to purchase shares,
and payments that a mutual savings association is required to make under the
terms of a deposit instrument.

         Under the revised OTS rules, capital distributions also include a
savings association's payment to repurchase, redeem, retire, or otherwise
acquire any of its shares or other ownership interests, any payment to
repurchase, redeem or otherwise acquire debt instruments included in its total
capital, and any extension of credit to finance an affiliate's acquisition of
those shares or interests. Additionally, a capital distribution includes any
direct or indirect payment of cash or other property to owners or affiliates
made in connection with a corporate restructuring. The revised rule also defines
as a capital distribution any transaction the OTS or the FDIC determines, by
order or regulation, to be in substance a distribution of capital.

         A final category of capital distribution under the revised OTS rules is
any other distribution charged against a savings association's capital accounts
if the savings association would not be well capitalized following the
distribution. As such, the revised capital distribution rules of the OTS do not
apply to capital distributions by wholly-owned operating subsidiaries of savings
associations. This is true because generally, for reporting purposes, the
accounts of a wholly-owned subsidiary are consolidated with those of the parent
savings association and any distributions by such subsidiary would not affect
the capital levels of the parent savings association.

         For regulatory capital purposes, where the consolidated subsidiary is
not wholly owned, the balance sheet account "minority interests in the equity
accounts of subsidiaries that are fully consolidated" may be included in Tier 1
capital and total capital if certain conditions are met. Distributions by such
consolidated subsidiaries to shareholders other than the savings association
reduce the cited balance sheet account and, therefore, reduce capital.
Consequently, distributions by subsidiaries that are not wholly owned by the
savings association are subject to the revised OTS capital distribution rules if
the savings association will not be well capitalized following the distribution.

         The revised OTS rule requires all savings associations to file a notice
or an application for approval before making a capital distribution. A savings
association must file an application if the association is not eligible for
expedited treatment under the application processing rules of the OTS or the
total amount of all capital distributions, including the proposed capital
distribution, for the applicable calendar year would exceed an amount equal to
the


                                     -114-
<PAGE>   117



savings association's net income for that year to date plus the savings
association's retained net income for the preceding two years.

         A savings association must file only a notice whenever an application
is not required under the above standards and any of the following criteria are
satisfied:

         -     the savings association will not be at least adequately
               capitalized following the capital distribution;

         -     the capital distribution would reduce the amount of, or retire
               any part of the savings association's common or preferred stock,
               or retire any part of debt instruments such as notes or
               debentures included in the savings association's capital;

         -     the proposed distribution would violate a prohibition contained
               in any applicable statute, regulation, or agreement between the
               savings association and the OTS, or the FDIC, or a condition
               imposed on the savings association in an OTS-approved application
               or notice; or

         -     the savings association is a subsidiary of a savings and loan
               holding company.

         If neither the savings association nor the proposed capital
distribution meet any of the criteria listed in the previous paragraph, the
savings association is not required to file a notice or an application before
making a capital distribution.

         Under the revised rule, the OTS will review a savings association's
notice or application and may disapprove a notice or deny an application if the
OTS makes any of the following determinations:

         -     The savings association will be undercapitalized, significantly
               undercapitalized, or critically undercapitalized under the prompt
               corrective action regulations of the OTS following the capital
               distribution;

         -     The proposed capital distribution raises safety and soundness
               concerns; or

         -     The proposed capital distribution violates a prohibition
               contained in any statute, regulation, agreement between the
               savings association and the OTS (or the FDIC), or a condition
               imposed on the savings association in an OTS-approved application
               or notice.

         Qualified Thrift Lender Test. Federal savings associations must meet a
qualified thrift lender test or they become subject to operating restrictions.
Until recently, the chief restriction was the elimination of borrowing rights
from the Federal Home Loan Bank. However, with passage of the Gramm-Leach-Bliley
Financial Modernization Act of 1999 by Congress, the failure to maintain
qualified thrift lender status will not affect borrowing rights with the Federal
Home Loan Bank. Notwithstanding these changes, Mutual Savings anticipates that
it will maintain an appropriate level of investments consisting primarily of
residential mortgages, mortgage-backed securities and other mortgage-related
investment, and otherwise qualify as a qualified thrift lender. The required
percentage of these mortgage-related investments is 65% of portfolio assets.
Portfolio assets are all assets minus intangible assets, property used by the
institution in conducting its business and liquid assets equal to 10% of total
assets. Compliance with the qualified thrift lender test is determined on a
monthly basis in nine out of every twelve months.

         Transactions With Affiliates. Generally, federal banking law requires
that transactions between a savings institution or its subsidiaries and its
affiliates must be on terms as favorable to the savings institution as
comparable transactions with non-affiliates. In addition, some transactions can
be restricted to an aggregate percentage of the savings institution's capital.
Collateral in specified amounts must usually be provided by affiliates in order
to

                                     -115-

<PAGE>   118


receive loans from the savings institution. In addition, a savings institution
may not extend credit to any affiliate engaged in activities not permissible for
a bank holding company or acquire the securities of any affiliate that is not a
subsidiary. The OTS has the discretion to treat subsidiaries of savings
institution as affiliates on a case-by-case basis. For a more complete
discussion of these restrictions, see "Mutual Savings--Federal Regulation Prior
to Restructuring--Transactions with Affiliates" above.

         Liquidity Requirements. All federal savings institutions are required
to maintain an average daily balance of liquid assets equal to a percentage of
the sum of its average daily balance of net withdrawable deposit accounts and
borrowings payable in one year or less. Depending on economic conditions and
savings flows of all savings institutions, the OTS can vary the liquidity
requirement from time to time between 4% and 10%. Monetary penalties may be
imposed on institutions for liquidity requirement violations.

         Federal Home Loan Bank System. Following the restructuring, the Banks
will remain members of the Federal Home Loan Bank of Chicago, which is one of 12
regional Federal Home Loan Banks. Each Federal Home Loan Bank serves as a
reserve or central bank for its members within its assigned region. It is funded
primarily from funds deposited by financial institutions and proceeds derived
from the sale of consolidated obligations of the Federal Home Loan Bank System.
It makes loans to members pursuant to policies and procedures established by the
board of directors of the Federal Home Loan Bank.

         As a member, we are required to purchase and maintain stock in the
Federal Home Loan Bank of Chicago in an amount equal to at least 1% of our
aggregate unpaid residential mortgage loans, home purchase contracts or similar
obligations at the beginning of each year, or 20% of our outstanding advances,
whichever is larger. Mutual Savings and First Northern Savings currently are in
compliance with this requirement and will be in compliance following the
restructuring. The Federal Home Loan Bank imposes various limitations on
advances such as limiting the amount of real estate related collateral to 30% of
a member's capital and limiting total advances to a member.

         Under the recently enacted Gramm-Leach-Bliley Financial Modernization
Act of 1999, Mutual Savings and First Northern Savings are voluntary members of
the Federal Home Loan Bank of Chicago. The banks could withdraw or significantly
reduce their stock ownership in the Federal Home Loan Bank of Chicago, although
they have no current intention to do so. In the past, the Federal Home Loan
Banks provided funds for programs to resolve the problems created by troubled
savings institutions and also contribute to affordable housing programs through
direct loans or interest subsidies on advances targeted for community investment
and low- and moderate-income housing projects. These contributions have
adversely affected the level of Federal Home Loan Bank dividends paid and could
continue to do so in the future.

         Federal Reserve System. The Federal Reserve System requires all
depository institutions to maintain noninterest bearing reserves at specified
levels against their checking, NOW, and Super NOW checking accounts and
non-personal time deposits. The balances maintained to meet the reserve
requirements imposed by the Federal Reserve System may be used to satisfy the
OTS liquidity requirements. Savings institutions have authority to borrow from
the Federal Reserve System "discount window," but Federal Reserve System policy
generally requires savings institutions to exhaust all other sources before
borrowing from the Federal Reserve System.

MHC REGULATION

         General. Upon completion of the restructuring, MHC will become a
federal mutual holding company within the meaning of Section 10(o) of the Home
Owners' Loan Act. As such, MHC will be required to register with and be subject
to OTS examination and supervision as well as reporting requirements. In
addition, the OTS will have enforcement authority over the MHC and its
non-savings institution subsidiaries. Among other things, this authority permits
the OTS to restrict or prohibit activities that are determined to be a serious
risk to the financial safety, soundness or stability of a subsidiary savings
bank.



                                     -116-
<PAGE>   119

         Permitted Activities. A mutual holding company is permitted to, among
other things:

         -     invest in the stock of a savings institution;

         -     acquire a mutual institution through the merger of such
               institution into a savings institution subsidiary of such mutual
               holding company or an interim savings institution of such mutual
               holding company;

         -     merge with or acquire another mutual holding company, one of
               whose subsidiaries is a savings institution;

         -     acquire non-controlling amounts of the stock of savings
               institutions and savings institution holding companies, subject
               to various restrictions;

         -     invest in a corporation the capital stock of which is available
               for purchase by a savings institution under federal law or under
               the law of any state where the subsidiary savings institution or
               institutions have their home offices;

         -     furnish or perform management services for a savings institution
               subsidiary;

         -     hold, manage or liquidate assets owned or acquired from a savings
               institution subsidiary;

         -     hold or manage properties used or occupied by a savings
               institution subsidiary; and

         -     act as a trustee under deed or trust.

         As a result of the Gramm-Leach-Bliley Financial Modernization Act of
1999, the activities of a newly formed mutual holding company are restricted to
those of a financial nature permitting securities and insurance activities as
well as affiliations with financial companies such as insurance and securities
firms.

         Waiver of Dividends. It has been the policy of a number of mutual
holding companies to waive the receipt of dividends declared by their savings
institution subsidiaries or mid-tier stock holding companies. Under OTS
regulations, the MHC may waive dividends from Bank Mutual only if the MHC
provides the OTS with written notice of its intent to waive its rights to
receive dividends 30 days prior to the proposed date of payment of the dividend
and the OTS does not object to such waiver. The OTS will not object to the
waiver if the following two determinations are made:

         -     the waiver would not be detrimental to the safe and sound
               operation of the savings association; and

         -     the board of directors of the MHC expressly determines that
               waiver of the dividend by the MHC is consistent with the
               directors' fiduciary duties to the mutual members of the MHC.

         Initially following the restructuring, the MHC expects to waive
dividends declared by Bank Mutual. The proposed management of the MHC believes
this is consistent with fiduciary duties owed to members of the MHC; among other
reasons, certain adverse tax consequences that would result from payment of the
dividend to the MHC. In addition, management believes that capital held in Bank
Mutual will be as productive, if not more productive, than capital held at the
MHC level.

         If the MHC waives any dividend from Bank Mutual, then Bank Mutual would
pay such dividend only to its public shareholders. The MHC's decision as to
whether to waive a particular dividend will depend on a number of factors,
including its capital needs, the investment alternatives available to the MHC as
compared to those available to Bank Mutual, and the possibility of regulatory
approvals.

BANK MUTUAL REGULATION

         After the restructuring, Bank Mutual, as a federal stock corporation in
a mutual holding company structure, will be deemed a federal mutual holding
company within the meaning of Section 10(o) of the Home Owners' Loan Act. Bank
Mutual will be required to register and file reports with the OTS and will be
subject to regulation and examination by the OTS. In addition, the OTS will have
enforcement authority over Bank Mutual and any

                                      -117-
<PAGE>   120


nonsavings institution subsidiary. The OTS can restrict or prohibit activities
that it determines to be a serious risk to Bank Mutual. This OTS regulation is
intended primarily for the protection of Mutual Savings' depositors and not for
the benefit of you, as BankS Mutual's shareholders.

         Bank Mutual will also be subject to the regulation and supervision of
the SEC and will be required to file certain reports with, and otherwise comply
with, the rules and regulations of the SEC. Certain of the SEC's rules and
regulations are designed to protect you, as Bank Mutual's shareholders.

ACQUISITION OF BANK MUTUAL

         Under federal law, no person may acquire control of Bank Mutual, Mutual
Savings, or First Northern Savings without first obtaining, as summarized below,
the approval of such acquisition of control by the OTS (or another federal
banking regulator).

         Under the federal Change in Bank Control Act and the Savings and Loan
Holding Company Act, any person, including a company, or group acting in
concert, seeking to acquire 10% or more of the outstanding shares of Bank Mutual
must file a notice with the OTS. In addition, any person or group acting in
concert seeking to acquire more than 25% of the outstanding shares of Bank
Mutual's common stock will be required to obtain the prior approval of the OTS.
Under regulations, the OTS generally has 60 days within which to act on such
applications, taking into consideration certain factors, including the financial
and managerial resources of the acquiror, the convenience and needs of the
communities served by Bank Mutual, Mutual Savings and First Northern Savings,
and the antitrust effects of the acquisition.


                                    TAXATION

         GENERAL. The following discussion is intended only as a summary and
does not purport to be a comprehensive description of the federal tax rules
applicable to Mutual Savings, the MHC or Bank Mutual. In addition, this
discussion does not consider the effect of foreign, state and local taxes. For
federal income tax purposes, Mutual Savings reports its income on the basis of a
taxable year ending December 31, uses the accrual method of accounting, and is
generally subject to federal income taxation in the same manner as other
corporations. Following the restructuring, Bank Mutual, Mutual Savings and First
Northern Savings will constitute an affiliated group of corporations and,
therefore, will be eligible to report their income on a consolidated basis.
Because the MHC will own less than 80% of the common stock of Bank Mutual, it
will not be a member of that affiliated group and will report its income on a
separate return.

         CORPORATE ALTERNATIVE MINIMUM TAX. The Internal Revenue Code of 1986,
as amended, imposes a tax on alternative minimum taxable income ("AMTI") at a
rate of 20%. Only 90% of AMTI can be offset by net operating loss carryovers of
which Mutual Savings currently has none. AMTI is also adjusted by determining
the tax treatment of certain items in a manner that negates the deferral of
income resulting from the regular tax treatment of those items. Thus, Mutual
Savings' AMTI is increased by an amount equal to 75% of the amount by which
Mutual Savings' adjusted current earnings exceeds it AMTI, determined without
regard to this adjustment and prior to reduction for net operating losses.

         ELIMINATION OF DIVIDENDS; DIVIDENDS RECEIVED DEDUCTION. Bank Mutual may
exclude from its income 100% of dividends received from Mutual Savings and First
Northern as a member of the same affiliated group of corporations. Because,
following the restructuring, the MHC will not be a member of the affiliated
group, it will not qualify for such 100% dividends exclusion, but will be
entitled to deduct 80% of the dividends it receives from Bank Mutual so long as
it owns more than 20% of the common stock of Bank Mutual.

<PAGE>   121


                       THE RESTRUCTURING AND THE OFFERING

GENERAL

         Mutual Savings' board of directors initially approved Mutual Savings'
plan of restructuring on February 21, 2000. The board adopted the plan
unanimously. The plan of restructuring subsequently has been amended, also with
unanimous board approval, and when we refer to the plan of restructuring, it
includes amendments. Under the plan, Mutual Savings will reorganize from a
Wisconsin-chartered mutual savings bank into a holding company structure in
which Mutual Savings' depositors will hold all of the voting and liquidation
rights in the MHC, which in turn will own a majority interest in Bank Mutual, a
mid-tier holding company. The remaining interest in Bank Mutual will be held by
public shareholders. Bank Mutual will wholly-own Mutual Savings, which will
convert from mutual form into a federally-chartered stock savings bank.

         The plan of restructuring and the plan of stock issuance remain subject
to regulatory approval by the Office of Thrift Supervision. The plan of
restructuring also requires approval of the members of Mutual Savings. After we
receive all the required regulatory approvals and member approval, we will
complete the restructuring which we describe in this prospectus.

         We anticipate that the offering will be completed contemporaneously
with or immediately following the restructuring. We also intend to complete the
First Northern merger contemporaneously with or immediately following the
restructuring. Mutual Savings does not anticipate that it will complete the
restructuring if the offering and the First Northern merger cannot be completed.

         For purposes of this discussion, we use "Stock Bank" to refer to Mutual
Savings in the post-restructuring stock form. References to Mutual Savings
include Mutual Savings in its current mutual form or in its post-restructuring
stock form, as indicated by the context.

DESCRIPTION OF THE RESTRUCTURING

         Following receipt of all required regulatory approvals and approval of
the plan of restructuring by the members, the restructuring will be effected in
a manner approved by the OTS that is consistent with the purposes of the plan of
restructuring and applicable law.

         Immediately prior to these transactions, Mutual Savings will have
converted to a federally-chartered mutual savings bank. Thereafter, a
newly-formed, federally-chartered, stock savings bank will merge with and into
Mutual Savings. The resulting Stock Bank will be a continuation of Mutual
Savings. All of Mutual Savings' right, title and interest in and to all property
will, by operation of law, immediately vest in the stock bank, without the
necessity of any conveyance or transfer and without any further act. The Stock
Bank will have, hold, and enjoy the same in its right and fully and to the same
extent as the same was possessed, held, and enjoyed by Mutual Savings, although
in the merger all stock of the MHC held by Mutual Savings will be cancelled. The
Stock Bank will continue to have, succeed to, and be responsible for all the
rights, liabilities, and obligations of Mutual Savings and will maintain its
headquarters operations at Mutual Savings's present location.

         The MHC and Bank Mutual will not retain any assets of Mutual Savings
that are required by the Stock Bank in order to satisfy capital and reserve
requirements of federal law. All assets, rights, obligations and liabilities of
whatever nature of Mutual Savings that are not expressly retained by the MHC or
Bank Mutual shall be deemed transferred to the Stock Bank. Mutual Savings will
apply to the OTS to allocate up to $100,000 in capital at the MHC level in
connection with the restructuring. In addition, Mutual Savings will contribute
approximately $40.0 million to the initial capital of Bank Mutual, assuming the
midpoint of the offering range. This contributed capital, together with a
substantial part of the proceeds of the offering and funds from First Northern,
will be used to pay a portion of the consideration to First Northern
shareholders in the First Northern merger. Bank Mutual may



                                     -119-
<PAGE>   122

distribute additional capital to the MHC following the restructuring, subject to
OTS regulations governing capital distributions. Mutual Savings and First
Northern Savings are expected to pay dividends to Bank Mutual following the
restructuring, in accordance with the OTS regulations.

EFFECTS OF THE RESTRUCTURING

         GENERAL. The Stock Bank will be authorized to exercise any and all
powers, rights and privileges of, and shall be subject to all limitations
applicable to, stock savings banks chartered under federal law. The initial
board of directors of the Stock Bank will be comprised of the existing directors
of Mutual Savings, plus Michael Meeuwsen, the chief executive officer of First
Northern. Thereafter, Bank Mutual, as the holder of shares of the Stock Bank's
voting stock will elect the Stock Bank's board of directors. It is expected that
present management of Mutual Savings will continue as the management of the
Stock Bank following the restructuring.

         The restructuring will not affect Mutual Savings's present business of
accepting deposits and investing its funds in loans and other investments
permitted by law, except that all those functions will be assumed by the Stock
Bank. The restructuring will not result in any change in the existing services
provided to depositors and borrowers, or in its existing offices, management and
staff. The Stock Bank will be subject to regulation, supervision and examination
by the OTS and the FDIC.

         DEPOSITS AND LOANS. The Stock Bank will be owned by Bank Mutual.
However, upon the effective date of the restructuring, the voting, ownership and
liquidation rights of members of Mutual Savings will become the rights of
members of the MHC, subject to the conditions specified below. Members of Mutual
Savings at the effective date will automatically become the members of the MHC.
Each deposit account in Mutual Savings at the effective date will become a
deposit account in the Stock Bank in the same amount and upon the same terms and
conditions, except that the holder of each such deposit account will have
ownership and membership rights with respect to the MHC rather than the Stock
Bank for so long as such holder maintains a deposit account with the Stock Bank.
All insured deposit accounts of Mutual Savings that are transferred to the Stock
Bank will continue to be federally insured up to the legal maximum by the FDIC
in the same manner as deposit accounts existing in Mutual Savings immediately
prior to the restructuring. Any new deposit accounts established with the Stock
Bank after the restructuring will create membership and liquidation rights in
the MHC and will be federally insured up to the legal maximum by the FDIC. First
Northern depositors will not be members of the MHC.

         All loans and other borrowings from Mutual Savings shall retain the
same status with the Stock Bank after the restructuring as they had with Mutual
Savings immediately prior to the restructuring. Borrowers are not members of
Mutual Savings and, accordingly, will not have membership rights in the MHC.

         VOTING RIGHTS. As a Wisconsin-chartered mutual savings bank, Mutual
Savings has no authority to issue capital stock and, thus, no shareholders.
Control of Mutual Savings in its mutual form is vested in the board of
directors. After the restructuring, the members of the board of directors of
Mutual Savings, together with four First Northern directors, will become the
directors of MHC and Bank Mutual. They will be elected in three-year staggered
terms. The affairs of the Stock Bank will be directed by its board of directors,
and all voting rights as to the Stock Bank will be vested exclusively in Bank
Mutual, the holder of its outstanding voting stock.

         Following the restructuring, Bank Mutual will have the power to issue
shares of common stock to persons other than the MHC. But so long as the MHC is
in existence, the MHC will be required to own at least a majority of the voting
stock of Bank Mutual. By virtue of its majority ownership interest in Bank
Mutual, and Bank Mutual's ownership of the Stock Bank, the MHC generally will be
able to elect all directors of Bank Mutual and generally will be able to control
the outcome of most matters presented to the shareholders of Mutual Savings and
Bank Mutual for resolution by vote, excluding certain matters related to stock
compensation plans and certain votes regarding a conversion to stock form by the
MHC. The Stock Bank and Bank Mutual may issue any amount of non-voting stock to
persons other than the MHC.


                                     -120-

<PAGE>   123


         As a federally chartered mutual holding company, the MHC will have no
authorized capital stock and, thus, no shareholders. The MHC will be controlled
by members (that is, the depositors) of Stock Bank, and most members have
granted proxies in favor of Mutual's management. According to regulations of the
OTS, the revocable proxies that members of Mutual Savings have granted to the
board of directors of Mutual Savings, which confer on the board of directors of
Mutual Savings general authority to cast a member's vote on any and all matters
presented to the members, shall be deemed to cover the member's votes as a
member of the MHC, and such authority shall be conferred on the board of
directors of the MHC. The plan of restructuring also provides for the transfer
of proxy rights to the board of directors of the MHC. Accordingly, the board of
the MHC will, in effect, be able to govern the operations of the MHC, and hence
Mutual Savings, notwithstanding objections raised by members of the MHC, so long
as the board of directors has been appointed proxy for a majority of the
outstanding votes of members of the MHC, and such proxies have not been revoked.
In addition, all persons who become depositors of the Stock Bank following the
restructuring will have membership rights with respect to the MHC. Borrowers are
not members of Mutual Savings and, thus, will not receive membership rights in
the MHC.

         LIQUIDATION RIGHTS. In the event of a voluntary liquidation of Mutual
Savings prior to the restructuring, holders of deposit accounts in Mutual
Savings would be entitled to distribution of any assets of Mutual Savings
remaining after the claims of such depositors, to the extent of their deposit
balances, and all other creditors are satisfied. Following the restructuring,
the holders of the common stock, including the MHC, would be entitled to any
assets remaining upon a liquidation, dissolution or winding-up of Mutual Savings
and, except through their liquidation interests in the MHC, discussed below,
holders of deposit accounts in Mutual Savings would have no interest in any such
assets.

         In the event of a voluntary or involuntary liquidation, dissolution or
winding-up of the MHC following consummation of the restructuring, holders of
deposit accounts in Mutual Savings would be entitled, pro rata to the value of
their accounts, to distribution of any assets of the MHC remaining after the
claims of all creditors of the MHC are satisfied. Shareholders of Bank Mutual
will have no liquidation or other rights with respect to the MHC in their
capacities as such.

         There currently are no plans to liquidate the Stock Bank or the MHC in
the future. Federal law and regulations require that any mutual savings bank
which converts to a stock savings bank set aside a "liquidation account"
representing its net worth as of the time of conversion. While former members of
the mutual savings bank would have a right under some circumstances to
participate in a distribution of this account upon a liquidation of the savings
bank, the possibility of such a liquidation ever occurring is extremely remote.

         SUBSCRIPTION AND PREEMPTIVE RIGHTS. Under OTS regulations, depositors
of Mutual Savings are entitled to priority subscription rights to purchase
shares of capital stock of the MHC in the event that the MHC converts from
mutual to stock form subsequent to the restructuring. Holders of the capital
stock of Bank Mutual shall not be entitled to preemptive rights with respect to
any shares of Bank Mutual that may be issued.

         If, at some point in the future, the MHC converted to stock ownership,
Mutual Savings' depositors will continue to have specified rights to purchase
shares of the resulting entity. The plan of restructuring provides that
outstanding shares of Bank Mutual would be converted into shares of a surviving
entity in manner which would reflect the proportionate interest of the public
shareholders in Bank Mutual as compared to MHC's interest. Mutual Savings'
depositors on the January 31, 1999 eligibility record date with the same account
number and account title at a future eligibility date would have first priority
in any full conversion subscription offering to Mutual Savings' depositors, with
other depositors on a specified future eligibility date having the next
priority. Any future full conversion would be subject to government rules and
regulations as then in effect, and we cannot assure that full conversion would
occur.

POSSIBLE CONVERSION OF THE MHC TO STOCK FORM

         It is possible that at some point in the future, Mutual would make a
"full conversion" from the mutual to the stock form of organization. The plan of
restructuring pursuant to which Mutual Savings is effecting the current
restructuring includes provisions which would govern treatment of various
constituencies' interest in such a full conversion.

         The plan of restructuring includes provisions intended to protect Bank
Mutual shareholders. In general, the provisions provide that Bank Mutual
shareholders would generally receive, in any subsequent full conversion, the
percentage of ownership in a successor entity as they would hold in Bank Mutual
just prior to that conversion.

         Under current OTS regulations, in the event of a full conversion,
depositors would have a first right to purchase any shares offered for sale by a
successor entity. The process for the offer and sale of any such shares would be
similar to the offering contemplated by the plan of restructuring, although
eligibility dates and purchase amounts, among other things, could differ. In
addition, the plan of restructuring provides that, in a full conversion, a first
priority for eligible account holders on January 31, 1999 with the same account
number and account title at the future eligibility date will be granted. These
account holders would have a right, before that of other depositors, to purchase
shares of any successor entity.

         Bank Mutual cannot assure that there will be any subsequent full
conversion or when one might occur. Also, any full conversion will be subject to
OTS or other governmental regulations as then in effect. Those regulations may
affect the treatment of Mutual Savings' depositors and Bank Mutual shareholders
in any full conversion. We also expect that such a conversion would require the
approval of the MHC's members.

FEDERAL TAX CONSEQUENCES OF THE RESTRUCTURING

         The following is a discussion of the material federal income tax
consequences of the restructuring of Mutual Savings. This discussion is for
general information only and does not address all tax consequences of the
restructuring. In addition, no information is provided with respect to the tax
consequences of the restructuring under applicable foreign, state or local laws.

         The restructuring will be accomplished as follows:

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

         (b)   Mutual Savings will form the MHC, a federally-chartered mutual
               holding company which will be subject to regulation by OTS. The
               MHC will form a transitory federal stock savings bank
               ("Transitory"). Mutual Savings has owned all of the shares of
               Bank Mutual and will contribute those shares to the MHC. The MHC
               will thereupon own all of the stock of both Bank Mutual and
               Transitory.

         (c)   Mutual Savings will convert to a federal stock savings bank. The
               depositors of Mutual Savings will receive deposit accounts in
               Stock Bank with the same terms and conditions as their deposit
               accounts in Mutual Savings.

         (d)   Transitory will merge into Stock Bank in a transaction in which
               the MHC will receive all of the stock of Stock Bank. Stock Bank
               will be the surviving corporation in the merger.

         (e)   The MHC will transfer the stock of Stock Bank to Bank Mutual so
               that Bank Mutual will hold all of the stock of Stock Bank, and
               the MHC will initially own 100% of the shares of common stock of
               Bank Mutual. The former depositors of Mutual Savings will hold
               all of the liquidation interests


                                     -122-

<PAGE>   125
               and voting rights in the MHC, for so long as, and to the extent,
               they continue to maintain their qualifying deposits with Stock
               Bank.

         (f)   Simultaneously with the First Northern merger, Bank Mutual will
               issue shares of its stock to the public and the Bank Mutual
               employee benefit plans for cash in the subscription offering at
               the price to purchasers at $10 per share.

         (g)   The initially issued stock of Stock Bank, which will be
               constructively received by the former Mutual Savings' depositors
               when Mutual Savings becomes a stock savings bank under step (c)
               above, will be issued to the MHC in exchange for liquidation
               interests in the MHC which will be held by Mutual Savings'
               depositors.


         In addition, as a result of the First Northern merger, Bank Mutual will
be the sole shareholder of First Northern Savings.

         Bank Mutual will concurrently offer for sale shares of its common stock
pursuant to the plan of restructuring. The amount of Bank Mutual common stock to
be offered to the public will be determined so that the total Bank Mutual issued
to First Northern shareholders in the First Northern Merger, the public, and
reserved for options or the other compensation programs for directors and
employees of Bank Mutual and its subsidiaries will constitute less than 49.9% of
the total common stock of Bank Mutual. The balance of the common stock of Bank
Mutual will be owned by the MHC. As a result of these transactions:

         -      Mutual Savings and First Northern Savings will be a wholly owned
                subsidiary of Bank Mutual;

         -      Bank Mutual will be a majority owned subsidiary of the MHC; and

         -      the depositors of Mutual Savings will hold liquidation interests
                in the MHC.

         Under this structure:

         -      the conversion of Mutual Savings from a state-chartered mutual
                savings bank to a federal savings bank, and then to a federal
                stock savings bank, is intended to be a reorganization under
                Section 368(a)(1)(F) of the Code;

         -      the exchange of the shares of Mutual Savings' initial common
                stock deemed constructively received by depositors for
                liquidation interests and voting rights in the MHC is intended
                to be part of a tax-free exchange under Section 351 of the Code;
                and

         -      the First Northern merger is intended to be a reorganization
                under Section 368(a)(1)(A) of the Code.

         Under the plan of restructuring, consummation of the restructuring is
conditioned upon, among other things, the prior receipt by Mutual Savings of
either a private letter ruling from the IRS or an opinion of Mutual Savings'
counsel as to the federal income tax consequences of the restructuring to Mutual
Savings (in both its mutual and stock form), the MHC, Bank Mutual and the
eligible account holders and supplemental account holders. In Rev. Proc. 2000-3,
2000-1 I.R.B. 103, the IRS announced that it will not rule on whether a
transaction qualifies as a tax-free reorganization under Section 368(a)(1)(F) of
the Code or as a tax-free exchange of stock for stock in the formation of a
holding company under Section 351 of the Code, but that it will rule on
significant subissues that must be resolved to determine whether the transaction
qualifies under either of these Code sections.

         Based in part upon certain representations of Mutual Savings and First
Northern and customary assumptions, Quarles & Brady LLP, Mutual's counsel, will
issue its opinion regarding certain federal income tax consequences of the
restructuring. Mutual Savings has requested a private letter ruling from the IRS
regarding certain significant subissues associated with the restructuring.



                                     -123-

<PAGE>   126

         In the following discussion, "Mutual Bank" refers to Mutual Savings
before the restructuring and "Stock Bank" refers to Mutual Savings after the
restructuring. With regard to the restructuring, Quarles & Brady will issue its
opinion to the effect that:

         (1)    the conversion of Mutual Savings from a state-chartered mutual
                savings bank to a federal savings bank, and then to a federal
                stock savings bank, will constitute a "reorganization" under
                Section 368(a)(1)(F) of the Code, and Mutual Savings (in either
                its status as Mutual Bank or Stock Bank) will not recognize gain
                or loss as a result of the reorganization;

         (2)    the basis of each asset of Mutual Bank received by Stock Bank in
                the reorganization will be the same as Mutual Bank's basis for
                such asset immediately prior to the reorganization;

         (3)    the holding period of each asset of Mutual Bank received by
                Stock Bank in the reorganization will include the period during
                which such asset was held by Mutual Bank prior to the
                reorganization;

         (4)    Mutual Bank's depositors will recognize no gain or loss upon
                their constructive receipt of shares of Stock Bank common stock
                solely in exchange for their interests (i.e., liquidation
                interests and voting rights) in Mutual Bank;

         (5)    no gain or loss will be recognized by the depositors of Mutual
                Savings (formerly Mutual Bank) upon the transfer to the MHC of
                shares of Stock Bank common stock they constructively receive in
                the reorganization in exchange for interests (i.e., liquidation
                interests and voting rights) in the MHC;

         (6)    no gain or loss will be recognized by depositors of Mutual Bank
                upon the issuance to them of deposits in Stock Bank in the same
                dollar amount as their deposits in the Mutual Bank;

         (7)    no gain or loss will be recognized by those that purchase shares
                of Bank Mutual in the subscription offering upon the transfer of
                cash to Bank Mutual in exchange for shares of common stock of
                Bank Mutual; and

         (8)    no gain or loss will be recognized by Bank Mutual upon the
                issuance of shares of Bank Mutual in exchange for cash in the
                subscription offering.

         The opinion of Quarles & Brady is not binding upon the Internal Revenue
Service or any court. Accordingly, we cannot assure you that the Internal
Revenue Service will not contest the conclusions expressed in Quarles & Brady's
opinion, or, if it does so, that a court will not agree with the IRS' position.

                             ACCOUNTING CONSEQUENCES

         The restructuring will be accounted for at historical cost in a manner
similar to pooling of interest accounting in accordance with generally accepted
accounting principles. Accordingly, the carrying value of Mutual Savings'
assets, liabilities and equity will not be affected by the restructuring and
will be reflected in the Stock Bank's financial statements at their historical
amounts.

         The First Northern merger will be accounted for as a purchase in
accordance with generally accepted accounting principles. Accordingly, the
assets and liabilities of First Northern will be initially carried on all
applicable financial statements at fair value as of the merger date and the
excess of the purchase price over the fair value of the net assets will be
recorded as an intangible asset to be amortized in future periods.

CONDITIONS TO THE RESTRUCTURING

         Consummation of the restructuring is subject to the receipt of all
requisite regulatory approvals, including various approvals of the OTS. We
cannot assure that all regulatory approvals will be received. Receipt of such
approvals from the OTS will not constitute a recommendation or endorsement of
the plan of restructuring or the related stock issuance plan by the OTS.
Completion also is subject to approval by a majority of the total number of
votes entitled to be cast by members of Mutual Savings at the special meeting
called for voting on the plan of restructuring. We must also receive rulings by
the IRS and/or opinions of Mutual Savings' attorneys with respect to the tax
consequences of the restructuring. See "Federal and State Tax Consequences of
the Restructuring."

AMENDMENT OR TERMINATION OF THE PLAN OF RESTRUCTURING

         If necessary or desirable, the terms of the plan of restructuring may
be substantively amended by the board of directors of Mutual Savings as a result
of comments from regulatory authorities or otherwise prior to the solicitation
of proxies from the members, and at any time thereafter with the concurrence of
the OTS. The plan of restructuring may be terminated by the board of directors
at any time prior to the special meeting and at any time thereafter with the
concurrence of the OTS. In its discretion, the board of directors may modify or
terminate the plan of restructuring upon the order of the regulatory authorities
or to conform to new mandatory regulations of the OTS, without a resolicitation
of proxies or another meeting of the members, if the OTS concurs that such
resolicitation is not required. However, any material amendment of the terms of
the plan of restructuring that relate to the restructuring that occurs after the
special meeting shall require a resolicitation of members. The plan of
restructuring will be terminated if not completed within 24 months from the date
upon which the members of Mutual Savings approve it, and such period may not be
extended by Mutual Savings.

         The related stock issuance plan also may be amended or terminated.
Unless an extension is granted by the OTS, the stock issuance plan shall be
terminated if not completed within 90 days of the date of approval of the stock
issuance plan by the OTS.

THE OFFERING

         Contemporaneously with the restructuring, Bank Mutual is offering
shares of its common stock to persons other than the MHC. Bank Mutual is
offering between a minimum of 4,633,564 shares and a maximum of 7,178,464 shares
of common stock in the offering, subject to adjustment to up to 8,641,781 shares
in the event the estimated pro forma market value of the common stock has
increased at the conclusion of the offering. The shares sold in the offering
will be in addition to shares which will be issued by Bank Mutual in the First
Northern merger.

         The offering will expire at 10:00 a.m., Central Time, on the expiration
date, unless extended by Mutual Savings. A minimum purchase of 25 shares of
common stock is required in order to participate in the offering. Bank Mutual
may cancel the offering at any time, and orders for common stock that have been
submitted prior thereto are subject to cancellation under such circumstances.

         As described in more detail below, non-transferable rights to subscribe
for the common stock in the subscription offering have been granted to certain
persons according to certain preference categories. Subject to the prior rights
of holders of subscription rights and the requirements of the First Northern
merger, Mutual Savings may also offer shares of common stock in a community
offering to certain members of the general public. Mutual Savings may reject, in
whole or in part, orders received in the community offering in its sole
discretion.

         EXPIRATION DATE FOR THE SUBSCRIPTION OFFERING. The subscription
offering will expire at 10:00 a.m., Central Time, on __________, 2000, unless we
extend this period for up to 45 days. We may further extend this period for
additional 60 day periods with the approval of the OTS. Subscription rights
which have not been exercised prior to the expiration date, as extended, will
become void. If an extension beyond _________, 2000 is

                                     -125-

<PAGE>   128

granted, Mutual Savings will resolicit subscribers, notifying them of the
extension of time and of their rights to change or cancel their orders. Each
subsequent extension may not exceed 60 days, and all extensions, in the
aggregate, may not last beyond _____________, 2002.

         If all shares have not been subscribed for by the expiration date, as
extended, all funds delivered to Mutual Savings will be returned promptly with
interest at our passbook savings rate and all deposit account withdrawal
authorizations will be canceled.

         SUBSCRIPTION OFFERING. In accordance with OTS regulations, subscription
rights have been granted pursuant to the stock issuance plan to the following
persons, the eligible subscribers, in the following order of priority:

         (1)    Eligible Account Holders--depositors with aggregate account
                balances of $50 or more on deposit ("qualifying deposit") at
                Mutual Savings as of January 31, 1999;

         (2)    the Mutual employee stock ownership plan, the "ESOP";

         (3)    Supplemental Eligible Account Holders--depositors, other than
                officers or directors of Mutual Savings or any of their
                associates, with a qualifying deposit, as of June 30, 2000);

         (4)    Other Members--depositors as of __________, 2000, the voting
                record date, who are not Eligible Account Holders or
                Supplemental Eligible Holders; and

         (5)    directors, officers and employees of Mutual Savings who do not
                qualify in earlier priorities.

         Subscription rights are non-transferable and have been granted to
eligible subscribers without charge. No one is required to purchase any shares
of common stock in the subscription offering. All subscriptions received will be
subject to the availability of common stock after satisfaction of subscriptions
of all eligible subscribers having prior rights in the subscription offering and
to the maximum purchase limitations and other terms and conditions set forth in
the stock issuance plan. See "Limitations on Common Stock Purchases." Among the
limitations are:

         Priority 1: Eligible Account Holders. Each eligible account holder will
receive, as first priority and without payment, non-transferable rights to
subscribe for common stock in an amount of up to $1.0 million, or 100,000
shares.

         If there are not sufficient shares available to satisfy all
subscriptions by eligible account holders, shares first will be allocated so as
to permit each subscribing eligible account holder to purchase a number of
shares sufficient to make such eligible account holder's total allocation equal
to the lesser of 100 shares or the number of shares subscribed for. Thereafter,
unallocated shares will be allocated among the remaining eligible account
holders whose subscriptions remain unfilled in the proportion that the amount of
their respective qualifying deposit bears to the total amount of qualifying
deposits of all eligible account holders whose subscriptions remain unfilled.
However, no fractional shares shall be issued.

         The subscription rights of eligible account holders who are also
directors or officers of Mutual Savings or their associates will be subordinated
to the subscription rights of other eligible account holders to the extent
attributable to increased deposits in the one-year period preceding January 31,
1999.

         Priority 2: The Employee Stock Ownership Plan. On a second priority
basis the Mutual ESOP will receive, without payment therefor, non-transferable
subscription rights to purchase up to 8% of the common stock to be issued in the
offering and the First Northern merger. As a tax-qualified employee benefit
plan, the ESOP expects to purchase 8% of those shares. Subscriptions by the ESOP
will not be aggregated with shares of common stock purchased directly by or
which are otherwise attributable to any other participants in the offering,
including subscriptions of any of Mutual Savings' directors, officers or
employee. It has not been determined whether the ESOP will subscribe for shares
in the offering or purchase shares in private transactions or on the open market
after completion of the offering.


                                     -126-
<PAGE>   129

         Priority 3: Supplemental Eligible Account Holders. To the extent that
there are shares remaining after satisfaction of the subscriptions by eligible
account holders and the ESOP, shares will be made available to supplemental
eligible account holders. Subject to that allocation, each supplemental account
holder will receive non-transferable rights to subscribe for common stock in an
amount of up to $1.0 million.

         If there are not sufficient shares available to satisfy all
subscriptions by supplemental eligible account holders, available shares first
will be allocated among subscribing supplemental eligible account holders so as
to permit each supplemental eligible account holder to purchase a number of
shares sufficient to make such supplemental eligible account holder's total
allocation equal to the lesser of 100 shares or the number of shares subscribed
for. Thereafter, unallocated shares will be allocated among the remaining
supplemental eligible account holders whose subscriptions remain unfilled in the
proportion that the amount of their respective qualifying deposit bears to the
total amount of qualifying deposits of all supplemental eligible account holders
whose subscriptions remain unfilled. However, no fractional shares shall be
issued.

         Priority 4: Other Members. To the extent that there are shares
remaining after satisfaction of the subscriptions by eligible account holders,
the ESOP and supplemental eligible account holders, shares will be made
available to other members. Each will receive non-transferable rights to
subscribe for common stock in an amount of up to $1.0 million.

         If there are not sufficient shares available to satisfy all
subscriptions by other members, available shares first will be allocated among
subscribing other members so as to permit each other member to purchase a number
of shares sufficient to make such other member's total allocation equal to the
lesser of 100 shares or the number of shares subscribed for. Thereafter,
unallocated shares will be allocated among the remaining other members whose
subscriptions remain unfilled in the proportion that the amount of their
respective qualifying deposit bears to the total amount of qualifying deposits
of all other members whose subscriptions remain unfilled. No fractional shares
shall be issued.

         Priority 5: Employees, Officers and Directors. On a fifth priority
basis, each employee, officer and director of Mutual Savings at the time of the
offering who is not eligible in the preceding priority categories shall receive
non-transferable subscription rights to subscribe for common stock in an amount
up to $1.0 million.

         PERSONS IN NON-QUALIFIED STATES OR FOREIGN COUNTRIES. We will make
reasonable efforts to comply with the securities laws of all states in the
United States in which persons entitled to subscribe for stock pursuant to the
stock issuance plan reside. However, we are not required to offer stock in the
subscription offering to any person who resides in a foreign country.

         FIRST NORTHERN MERGER. In connection with the First Northern merger,
Bank Mutual will issue shares to the First Northern shareholders as part of the
consideration for that transaction. Bank Mutual will issue to First Northern
shareholders at least the minimum number of shares needed to complete that
merger, and those shares will not be part of the stock offering. In addition, in
the event that shares remain available after the subscription offering, Bank
Mutual may set aside those shares and issue them in the First Northern merger,
rather than including them in the community offering or syndicated community
offering.

         COMMUNITY OFFERING. Subject to the availability of shares of common
stock after satisfaction of all subscriptions of eligible account holders, the
ESOP, supplemental eligible account holders, other members, and officers,
directors and employees, and any shares set aside for First Northern
shareholders, the remaining shares of the common stock may be offered in a
community offering to the public, with a preference to persons who are residents
of the counties where Mutual Savings or First Northern Savings maintain an
office. No individual who purchases common stock in the community offering may
subscribe for more than $1.0 million, or 100,000 shares.


                                      -127-

<PAGE>   130

         MUTUAL SAVINGS RESERVES THE RIGHT TO ACCEPT OR REJECT, IN WHOLE OR IN
PART, ANY OR ALL ORDERS IN THE COMMUNITY OFFERING, EITHER AT THE TIME OF RECEIPT
OF AN ORDER OR AS SOON AS PRACTICABLE FOLLOWING THE TERMINATION OF THE OFFERING.
IF A PART OF YOUR ORDER IS REJECTED, YOU MAY NOT CANCEL THE REMAINDER OF YOUR
ORDER.

         The counties in which Mutual Savings or First Northern Savings maintain
offices are Milwaukee, Barron, Brown, Calumet, Chippewa, Columbia, Dane, Dodge,
Door, Dunn, Eau Claire, Fond du Lac, Green Lake, Manitowoc, Marinette,
Outagamie, Ozaukee, Pierce, Polk, Rock, St. Croix, Sawyer, Shawano, Sheboygan,
Washburn, Waukesha, Waupaca and Winnebago Counties in Wisconsin, and Washington
County in Minnesota.

         The term "residents" includes persons who occupy a dwelling within
these counties and have established an ongoing physical presence in it, together
with an indication that such presence is not merely transitory in nature. To the
extent the person is a corporation or other business entity, the principal place
of business or headquarters shall be in these counties. We may utilize depositor
or loan records or such other evidence to make a determination as to whether a
person is a resident. In all cases, the determination of resident status will be
made by us in our sole discretion. No person may purchase more than $1.0 million
of common stock in the community offering. Allocation of shares if an o
oversubscription occurs will give preference to persons residing in the counties
listed above, and will be made in an o equitable manner determined by us.

         The community offering, if any, may commence concurrently with, during
or subsequent to the subscription offering and shall terminate no later than 45
days after the expiration of the subscription offering, unless extended by
Mutual Savings, with the approval of the OTS, if necessary. We may terminate the
community offering as soon as we have received orders in sufficient amount for
us to issue at least the minimum number of shares required to be issued,
4,633,564 shares.

         SYNDICATED COMMUNITY OFFERING. If any stock remains unsold in the
subscription and community offerings, we expect to use the services of
broker-dealers to sell such shares on a best efforts basis in a syndicated
community offering to be managed by Ryan, Beck. A syndicated community offering
may be conducted instead of or in addition to a community offering. It is
contemplated that no person may purchase more than $1.0 million of common stock
in the syndicated community offering.

         Neither Ryan, Beck nor any registered broker-dealer shall have any
obligation to take or purchase any shares of the common stock in the syndicated
community offering. However, Ryan, Beck has agreed to use its best efforts in
the sale of shares in any syndicated community offering. The syndicated
community offering may commence during the community offering, if any, or after
the community offering is terminated. We may terminate the syndicated community
offering at any time, but it must terminate no more than 45 days following the
expiration of the subscription offering, unless extended by Mutual Savings with
the approval of the OTS.

         If for any reason a syndicated community offering cannot be effected or
is not advisable and any shares remain unsold after the subscription and
community offerings, if any, Mutual will seek to make other arrangements for the
sale of the remaining shares. These other arrangements will be subject to the
approval of the OTS and to compliance with applicable state and federal
securities laws.

         MUTUAL SAVINGS RESERVES THE RIGHT TO ACCEPT OR REJECT, IN WHOLE OR IN
PART, ANY OR ALL ORDERS IN THE SYNDICATED COMMUNITY OFFERING, EITHER AT THE TIME
OF RECEIPT OF AN ORDER OR AS SOON AS PRACTICABLE FOLLOWING THE TERMINATION OF
THE OFFERING.

STOCK PRICING AND NUMBER OF SHARES TO BE ISSUED

         The plan of restructuring requires that the purchase price of the
common stock must be based on the appraised pro forma market value of the common
stock, as determined on the basis of an independent valuation. Mutual Savings
and Bank Mutual have retained RP Financial to make the independent valuation. RP
Financial's


                                     -128-
<PAGE>   131


fees for its services in making such appraisal (and a business plan relating to
the restructuring and stock offering) are estimated to be $120,000, plus
expenses. Mutual Savings and Bank Mutual will indemnify RP Financial and its
employees and affiliates against losses, including any losses in connection with
claims under federal securities laws, arising out of its services as appraiser,
except where RP Financial's liability results form its negligence or bad faith.

         RP Financial made its appraisal in reliance upon the information
contained in this prospectus, including the financial statements. RP Financial
also considered the following factors, among others:

- - -        the present and projected operating results and financial condition of
         Bank Mutual, Mutual Savings, First Northern, and the economic and
         demographic conditions in Mutual Savings' and First Northern's existing
         market area;

- - -        certain historical, financial and other information relating to Mutual
         Savings and First Northern;

- - -        a comparative evaluation of the operating and financial statistics of
         Mutual Savings and First Northern with those of other publicly traded
         mutual holding companies;

- - -        the aggregate size of the offering and issuance of common stock;

- - -        the impact of the stock offering and merger on Mutual Savings' net
         worth and earnings potential;

- - -        the proposed dividend policy of Bank Mutual and Mutual Savings; and

- - -        the trading market for securities of comparable institutions and
         general conditions in the market for such securities;

         In its review of the appraisal provided by RP Financial, the board of
directors of Mutual Savings reviewed the methodologies and the appropriateness
of the assumptions used by RP Financial in addition to the factors listed above,
and the board of directors believes that such assumptions were reasonable.

         RP Financial has estimated that in its opinion as of June 12, 2000, the
estimated pro forma market value of Mutual, assuming completion of the stock
offering and the First Northern merger, was between $144.5 million and $195.5
million, with a midpoint of $170.0 million.

         The board of directors of Mutual Savings has determined to sell shares
in the stock offering at $10.00 share. Based on that price, assuming the
issuance of 5,143,685 shares to former shareholder of First Northern, the pro
forma market value of Mutual Savings ranged between $195.9 million and $246.9
million, with a midpoint pro forma market value of $221.4 million. This is the
"estimated valuation range." The stock issuance plan provides that total
outstanding shares must reflect the estimated valuation range and that public
ownership will equal 49.9 percent of outstanding g shares, while the MHC's
ownership will equal 50.1 percent. Given the 5,143,685 shares to be issued to
the former g shareholders of First Northern, this results in an offering range
of between 4,633,564 and 7,178,464 shares, with a g midpoint of 5,906,014
shares. Following the stock offering and First Northern merger, shares
outstanding to the public g will therefore range between 9,777,249 and
12,322,149, with a midpoint of 11,049,699 shares. Total outstanding g shares,
held by the MHC and public owners, will range between 19,593,685 and 24,693,685.


         The appraisal was based in part upon Mutual Savings' financial
condition and operations, the financial g condition and operations of First
Northern, the effect of the First Northern merger and the effect of the
additional capital Bank Mutual will raise from the sale of common stock. RP
Financial's independent appraisal will be updated before we complete our
restructuring.

         The independent valuation is not intended, and must not be construed,
as a recommendation of any kind as to the advisability of purchasing the common
stock. In preparing the independent valuation, RP Financial has relied upon and
assumed the accuracy and completeness of financial and statistical information
provided by Mutual Savings or First Northern. RP Financial did not independently
verify the consolidated financial statements and other information provided by
Mutual Savings or First Northern, nor did RP Financial value independently the
assets or liabilities of Mutual Savings or First Northern. The independent
valuation considers Mutual Savings only


                                     -129-
<PAGE>   132


as a going concern and should not be considered as an indication of the
liquidation value of Mutual Savings. Moreover, because such independent
valuation is based on estimates and projections of a number of matters, all of
which are subject to change from time to time, no assurance can be given that
persons purchasing the common stock will be able to sell such shares at a price
equal to or greater than the $10.00 per share purchase price in the offering.
The $10.00 price per share was chosen by Mutual Savings' board of directors
because it is the price per share most commonly used in stock offerings
involving conversions and reorganizations of savings institutions.

         The maximum of the estimated valuation range may be increased up to 15%
and the number of shares of common stock to be issued in the restructuring and
offering may be increased to 27,626,185 shares and 8,641,781 shares,
respectively due to regulatory considerations, changes in the market and general
financial and economic conditions without the resolicitation of subscribers. See
"--Limitations on Common Stock Purchases" as to the method of distribution and
allocation of additional shares that may be issued in the event of an increase
in the estimated valuation range to fill unfilled orders in the offering.

         We may not sell any shares of common stock unless RP Financial confirms
to Mutual Savings, Bank Mutual, and the OTS that, to the best of its knowledge,
nothing of a material nature has occurred which, taking into account all
relevant factors, would cause RP Financial to conclude that the aggregate value
of the common stock is incompatible with its estimate of the pro forma market
value of the common stock at the conclusion of the offering.

         If RP Financial concludes that the pro forma market value of the common
stock is either more than 15% above the maximum of the estimated valuation range
or less than the minimum of the estimated valuation range, Mutual Savings and
Bank Mutual, after consulting with the OTS, may:

         (1)    terminate the plan and return all funds promptly with interest
                at Mutual Savings' passbook rate of interest on payments made by
                check, bank check or money order;

         (2)    establish a new estimated valuation range and either:

                (a)   hold a new stock offering; or
                (b)   provide subscribers the opportunity to change or cancel
                      their orders (a "resolicitation");

         (3)    take such other actions as permitted by the OTS in order to
                complete the restructuring.

If a resolicitation is commenced, unless an affirmative response is received
from a subscriber within a designated period of time, all funds will be promptly
returned to the subscriber as described above.

         Copies of the appraisal report of RP Financial, including any
amendments thereto, and the detailed memorandum of the appraiser setting forth
the method and assumptions for such appraisal are available for inspection at
the main office of Mutual Savings.

MARKETING ARRANGEMENTS

         Ryan, Beck & Co. Inc. We have engaged Ryan, Beck as financial and
marketing agent in connection with the offering of the common stock. Ryan, Beck
has agreed to use its best efforts to assist us with the solicitation of
subscriptions for shares of common stock in the offering.

         Ryan, Beck will receive an advisory and administrative fee of $100,000
and a marketing fee of 1.5% of the dollar amount of shares issued in the
subscription and community offering, excluding any shares that are used as
merger consideration. If shares which otherwise could be sold in the community
offering are set aside for use in the First Northern merger, Ryan, Beck will
also be paid a 1.5% fee, up to a maximum of $100,000, with respect to those
shares; no fee will be payable to Ryan, Beck in respect of other shares issued
in the First Northern merger in addition to the community offering. No marketing
fee will be paid related to the sale of common stock to officers, directors or
employees of Mutual Savings, or members of their immediate families or to the
ESOP. If there is a syndicated community offering, we will also pay Ryan, Beck a
management fee equal to 1.5% of the dollar amount of common stock sold in the
syndicated community offering, which fee, along with fees payable by us to any
broker-dealers including Ryan, Beck, for the shares they sell, will not exceed
5.5% of the aggregate purchase price of the common stock sold in the syndicated
community offering. Ryan, Beck will also be reimbursed for its reasonable
out-of-pocket expenses, up to $35,000 and its legal fees, up to $75,000.

         Directors, Officers and Employees. Directors and officers of Mutual
Savings may participate in the solicitation of offers to purchase common stock.
Other employees of Mutual Savings may participate in the offering in ministerial
capacities or provide clerical work in effecting a sales transaction. Such other
employees have been instructed not to solicit offers to purchase common stock or
provide advice regarding the purchase of common stock. Mutual Savings will rely
on Rule 3a4-1 under the Exchange Act, and sales of common stock will be
conducted within the requirements of Rule 3a4-1, so as to permit directors,
officers and employees to participate in the sale of common stock. No director,
officer or employee of Mutual Savings will be compensated in connection with his
or her participation by the payment of commissions or other remuneration based
either directly or indirectly on transactions in common stock.

PROCEDURE FOR PURCHASING SHARES IN SUBSCRIPTION AND COMMUNITY OFFERINGS

         Use of Order Forms. To purchase shares in the subscription offering and
the community offering, an executed order form with the required payment for
each share subscribed for, or with appropriate authorization for withdrawal from
a subscriber's deposit accounts at Mutual Savings (which must be given by
completing the appropriate blanks on the stock order form), must be received by
Mutual Savings by 10:00 a.m., Central Time, on the indicated expiration date,
unless extended. You may submit your order form by mail using the return
envelope provided or by overnight courier to the indicated address, or by
bringing your order form to our stock information center in our headquarters
office. Stock order forms which are not received by such time or are executed
defectively or are received without full payment (or correct withdrawal
instructions) are not required to be accepted. In addition, we are not obligated
to accept orders submitted on photocopied or facsimilied order forms. We have
the power to waive or permit the correction of incomplete or improperly executed
forms, but do not represent that we will do so.

         Once received, an executed order form may not be modified, amended or
rescinded without our consent unless we conduct a resolicitation of subscribers.
If resolicitation is commenced, subscribers will have an opportunity to change
or cancel their orders. Unless an affirmative response is received from a
subscriber within a designated timeframe, all funds will be promptly returned to
the subscriber with interest at Mutual Savings' passbook savings rate and all
account withdrawal authorizations will be canceled.


                                     -131-
<PAGE>   134

         In order to ensure that eligible account holders, supplemental eligible
account holders and other members are properly identified as to their stock
purchase eligibility, depositors must list on the stock order form all deposit
accounts as of the applicable eligibility record date, giving all names on each
account and the account numbers.

         To ensure that each purchaser received a prospectus at least 48 hours
prior to the expiration date for the offering, in accordance with Rule 15c2-8 of
the Exchange Act, no prospectus will be mailed later than five days prior to
such date or hand delivered any later than two days prior to such date.
Execution of the stock order form will confirm receipt or delivery in accordance
with Rule 15c2-8. Order forms will only be distributed when preceded or
accompanied by a prospectus.

         Payment for Shares. Payment for subscriptions may be made by personal
check, bank check, money order or by authorization of withdrawal from your
current deposit accounts maintained at Mutual Savings. Interest will be paid on
payments made by check, bank check or money order at our passbook savings rate
of interest from the date payment is received until the completion or
termination of the restructuring. If payment is made by authorization of
withdrawal from a deposit account, the funds authorized to be withdrawn will
remain in the account and continue to accrue interest at the contractual rate
until completion or termination of the restructuring, but a hold immediately
will be placed on such funds, thereby making them unavailable to the depositor.

         Mutual Savings will waive any applicable penalties for early withdrawal
from certificates of deposit. If the remaining balance in a certificate account
is reduced below the applicable minimal balance requirement at the time that the
funds are transferred under the authorization, the certificate will be canceled
at the time of the withdrawal, without penalty, and the remaining balance will
be converted into a statement savings account and will earn interest at the
statement savings rate.

         The ESOP will not be required to pay for the shares subscribed for at
the time it subscribes. Rather, the ESOP may pay for such shares of common stock
subscribed for at the $10.00 per share purchase price upon completion of the
offering; provided, that there is in force from the time of its subscription
until such time, a loan commitment acceptable to Mutual Savings from an
unrelated financial institution or from Bank Mutual to lend to the ESOP the
aggregate purchase price of the shares for which it subscribed. Bank Mutual
intends to provide such a loan to the ESOP.

         Owners of self-directed IRAs may use the assets of such IRAs to
purchase shares of common stock in the subscription and community offerings,
provided that such IRAs are not maintained at Mutual Savings. Persons with IRAs
maintained at Mutual Savings must have their accounts transferred to an
unaffiliated institution or broker-dealer to purchase shares of common stock in
the subscription and community offerings. In addition, the provisions of ERISA
and IRS regulations require that officers, trustees and ten percent shareholders
who use self-directed IRA funds to purchase shares of common stock in the
subscription and community offerings make such purchase for the exclusive
benefit of the IRAs. Assistance on how to transfer IRAs maintained at Mutual
Savings can be obtained from the Stock Information Center. Depositors interested
in using funds in an IRA to purchase common stock should contact the Stock
Information Center as soon as possible.

         Certificate Delivery. Certificates representing shares of common stock
purchased will be mailed to purchasers to the address specified by subscribers
on properly completed order forms, as soon as practicable following completion
of the offering. Any certificates returned as undeliverable will be disposed of
in accordance with applicable law.

STOCK INFORMATION CENTER

         If you have any questions regarding the offering or the restructuring,
please call the Stock Information Center at 800-_______, from 9:00 a.m. to 4:00
p.m., Central Time, Monday through Friday.

RESTRICTIONS ON TRANSFER OF SUBSCRIPTION RIGHTS AND SHARES OF COMMON STOCK

         Regulations prohibit any person with subscription rights from
transferring or entering into any agreement or understanding to transfer the
legal or beneficial ownership of the subscription rights issued under the stock
issuance plan or the shares of common stock to be issued upon their exercise.
Such rights may be exercised only by the person to whom they are granted and
only for such person's account. Each person exercising subscription rights will
be required to certify that the purchase is solely for such person's own account
and there is no agreement or understanding regarding the sale or transfer of
such shares. The regulations also prohibit any person from offering or making an
announcement of an offer or an intent to make an offer to purchase subscription
rights or shares of common stock prior to the completion of the restructuring.

         We will pursue any and all legal and equitable remedies (including
forfeiture) in the event we become aware of the transfer of subscription rights
and will not honor orders known by us to involve the transfer of such rights.

LIMITATIONS ON COMMON STOCK PURCHASES

         The stock issuance plan includes the following limitations on the
number of shares of common stock which may be purchased in the offering:

         (1)    No subscription for fewer than 25 shares will be accepted;

         (2)    No fractional shares will be issued;

         (3)    Purchasers in the subscription offering may subscribe for common
                stock in an amount up to $1,000,000.

         (4)    The tax-qualified employee benefit plans are permitted to
                purchase up to 8% of the shares of common stock issued in the
                offering and the merger and, as a tax-qualified employee benefit
                plan, the ESOP intends to purchase 8% of the shares of common
                stock issued in the offering and the First Northern merger;

         (5)    The current officers and directors of Mutual Savings and their
                associates, in the aggregate, excluding purchases by the
                tax-qualified employee benefit plans, may purchase up to 25% of
                the shares of stock issued in the offering and the First
                Northern merger. Each officer and director who does not qualify
                as an eligible account holder, supplemental eligible account
                holder or other member will be subject to the same purchase
                limitations as eligible account holders, supplemental eligible
                account holders and other members;

         (6)    Persons purchasing shares of common stock in the community
                offering or in the syndicated community offering may purchase
                common stock in an amount up to $1,000,000; and

         (7)    Except for the tax-qualified employee benefit plans, the maximum
                amount of shares of common stock purchased in all categories of
                the offering combined by any person, together with associates
                of, and groups of persons acting in concert with, such person,
                shall not exceed $1,000,000.

         Subject to any required regulatory approval and the requirements of
applicable laws and regulations, the maximum purchase amounts may be altered by
Bank Mutual, in its sole discretion and without further notice to or
solicitation of subscribers or other prospective purchasers, to the following
amounts: (i) increased, including to a level above 5% of the shares offered in
the offering, so long as orders exceeding 5% shall not in the aggregate, exceed
10% of the shares offered, or (ii) decreased to not less than 0.1% of the number
of shares of stock offered in


                                     -133-
<PAGE>   136


the offering and issued in the First Northern merger, or 12,322,149 shares. If
the purchase limitations are increased, subscribers for the maximum amount in
the subscription offering and, at Mutual Savings' discretion certain other large
subscribers will be given the opportunity to increase their subscriptions up to
the then applicable limit. Requests to purchase additional shares of common
stock under this provision will be determined by and in the sole discretion of
the Board of Directors of Mutual Savings and if necessary, allocated giving
priority in accordance with the priorities set forth in the plan of stock
issuance and described in this prospectus.

         If we sell more than 7,178,464 shares, the additional shares will be
allocated in accordance with the following priority:

         -      to fill the ESOP's subscription;
         -      if there is an oversubscription at the Eligible Account Holder
                level, to fill unfilled subscriptions of Eligible Account
                Holders;
         -      if there is an oversubscription at the Supplemental Eligible
                Account Holder level, to fill unfilled subscriptions of
                Supplemental Eligible Account Holders;
         -      if there is an oversubscription at the Other Member level, to
                fill unfilled subscriptions of Other Members;
         -      at Mutual's discretion, for issuance in the First Northern
                merger; and
         -      to fill unfilled subscriptions in the community offering.

         We have the sole discretion to determine whether prospective purchasers
are "associates" or "acting in concert," in accordance with the terms of the
stock issuance plan. Directors and officers are not treated as associates of
each other solely by virtue of holding such positions. The term "associate" of a
person is defined to mean:

         (1)    any corporation or organization (other than Mutual) of which
                such person is a director, officer or partner or is directly or
                indirectly, the beneficial owner of 10% or more of any class of
                equity securities;

         (2)    any trust or other estate in which such person has a substantial
                beneficial interest or as to which such person serves as trustee
                or in a similar fiduciary capacity; provided, however, that any
                tax-qualified or non-tax-qualified employee plan will not be
                deemed to be an associate of any director, or officer of Mutual,
                for purposes of aggregating total shares that may be acquired or
                held by directors and officers and their associates; and

         (3)    any relative or spouse of such person, or any relative of such
                spouse, who has the same home as such person or who is a
                director or officer of Mutual or any affiliate thereof; and

         "Acting in concert" means: (a) knowing participation in a joint
activity or interdependent conscious parallel action towards a common goal
whether or not pursuant to an express agreement, or (b) a combination or pooling
of voting or other interests in the securities of an issuer for a common purpose
pursuant to any contract, understanding, relationship, agreement or other
arrangement whether written or otherwise. A person or company which acts in
concert with another person or company ("other party") shall also be deemed to
be acting in concert with any person or company who is also acting in concert
with that other party, except that any tax-qualified employee stock benefit plan
as defined in 12 C.F.R. ss. 563b.2(a)(39) will not be deemed to be acting in
concert with its trustee or a person who serves in a similar capacity solely for
the purpose of determining whether stock held by the trustee and stock held by
the plan will be aggregated.

         We have the right in our sole discretion to reject any order submitted
by a person whose representations we believe to be false or who we otherwise
believe, either alone or acting in concert with others, is violating or
circumventing, or intends to violate or circumvent, the terms and conditions of
the stock issuance plan.


                                     -134-
<PAGE>   137


         The aggregate amount of Bank Mutual voting stock outstanding owned by
other than the MHC, as long as it exists, must be less than 50%.

RESTRICTIONS ON PURCHASE OR TRANSFER OF SHARES AFTER THE RESTRUCTURING

         All shares of common stock purchased in connection with the offering by
an officer or director of Mutual Savings will be subject to a restriction that
the shares not be sold for a period of one year following the date of purchase,
except in the event of the death or incompetence of such officer or director.
Each certificate for restricted shares will bear a legend giving notice of this
restriction on transfer, and instructions will be issued to the effect that the
transfer agent for Bank Mutual is to disregard any such attempted transfer. The
directors and officers of Bank Mutual and Mutual Savings will also be subject to
the federal insider trading rules and any other applicable requirements of the
federal securities laws.

         Purchases of outstanding shares of common stock of Bank Mutual by
directors or officers of Bank Mutual or Mutual Savings and their associates
during the three-year period following restructuring may be made only through a
broker or dealer registered with the SEC, except with the prior written approval
of the OTS. This restriction does not apply, however, to negotiated transactions
involving more than 1% of the outstanding common stock, or purchases of common
stock made and held by an tax-qualified or non-tax-qualified employee plan of
Mutual.

CONDITIONS TO THE OFFERING

         -      the sale in the offering, or issuance to a First Northern
                shareholders, of a minimum of 4,633,564 shares of common stock
                offered.

         In the event that the conditions mentioned above are not satisfied, all
funds received will be promptly returned with interest at Mutual Savings'
passbook rate and all withdrawal authorizations will be canceled.

         The restructuring, the offering and the First Northern merger are
interdependent. Mutual does not expect that any transaction will occur without
the others.


                   RESTRICTIONS ON ACQUISITION OF BANK MUTUAL

GENERAL

         The plan of restructuring provides for the conversion of Mutual Savings
from the mutual to the stock form of organization and the formation of a stock
holding company and a mutual holding company. See "The Restructuring and The
Offering -- General." Certain provisions in Bank Mutual's charter and bylaws and
in its benefit plans and agreements entered into in connection with the
restructuring, together with provisions of federal law and certain governing
regulatory restrictions, may have anti-takeover effects.

MUTUAL HOLDING COMPANY STRUCTURE

         The mutual holding company structure will restrict the ability of our
shareholders to effect a change of control of management because, as long as the
MHC remains in existence as a mutual savings bank holding company, it will
control a majority of Bank Mutual's voting stock. Moreover, the directors of the
MHC initially will be the directors of Bank Mutual. The MHC will be able to
elect all of the members of the Board of Directors of Bank Mutual, and as a
general matter, will be able to control the outcome of all matters presented to
the shareholders of Bank Mutual for a vote. See "The Restructuring and The
Offering -- Possible Conversion of the MHC to Stock Form."

CHANGE IN BANK CONTROL

         Federal law provides that no person, acting directly or indirectly or
through or in concert with one or more other persons, may acquire control of a
federal savings bank unless the OTS has been given 60 days prior written notice.
Federal law provides that no company may acquire control of a bank holding
company without the prior approval of the OTS. Any company that acquires control
becomes a "thrift holding company" subject to registration, examination and
regulation by the OTS.

         Pursuant to federal regulations, control is conclusively deemed to have
occurred when an entity, among other things, has acquired more than 25 percent
of any class of voting stock of the institution or the ability to control the
election of a majority of the directors of an institution. Moreover, control is
presumed to have occurred, subject to rebuttal, upon the acquisition of more
than 10 percent of any class of voting stock, or of more than 25 percent of any
class of stock, of a federal savings bank, where certain enumerated control
factors are also present in the acquisition.

         The OTS may prohibit an acquisition of control if:

         (1)    it would result in a monopoly or substantially lessen
                competition;

         (2)    the financial condition of the acquiring person might jeopardize
                the financial stability of the institution; or

         (3)    the competence, experience or integrity of the acquiring person
                indicates that it would not be in the interest of the depositors
                or of the public to permit the acquisition of control by such
                person.

These restrictions do not apply to the acquisition of stock by one or more
tax-qualified employee stock benefits plans, provided that the plan or plans do
not have beneficial ownership in the aggregate of more than 25 percent of any
class of our equity security.

BANK MUTUAL'S CHARTER AND BYLAWS

         General. Bank Mutual's charter and bylaws are available at Mutual's
administrative office or by writing or calling us, 4949 West Brown Deer Road,
Milwaukee, Wisconsin 53223, telephone number (414) 354-1500.

         Classified Board of Directors and Related Provisions. Bank Mutual's
board of directors is divided into three classes which are as nearly equal in
number as possible. Directors serve for terms of three years. As a result, each
year, only one-third of the directors are eligible to be elected and it would
take at least two years to elect a majority of our directors.

         Restrictions on Voting of Securities. The charter provides that for
five years after the restructuring any shares of common stock beneficially owned
directly or indirectly in excess of 10% by any person, other than the


                                     -136-
<PAGE>   139


MHC, will not be counted as shares entitled to vote, shall not be voted by any
person or counted as voting shares in connection with any matter submitted to
shareholders for a vote, and shall not be counted as outstanding for purposes of
determining a quorum or the affirmative vote necessary to approve any matter
submitted to the Shareholders for a vote. It is possible for such a person to
have voting authority for less than 10% of our shares, depending on how the
shares are registered.

         Prohibition Against Cumulative Voting. Bank Mutual's charter does not
permit cumulative voting by shareholders in the election of directors. Therefor,
the holders of a majority of the shares voted at a meeting, thus precluding a
majority shareholder from obtaining representation on the board of directors
unless the minority shareholder is able to obtain the support of a majority. In
accordance with the law governing mutual holding companies, the MHC must remain
the majority holder of Bank Mutual's voting stock.

         Additional Anti-Takeover Provisions. The provisions described above are
not the only provisions of our charter and bylaws having an anti-takeover
effect. For example, the charter authorizes the issuance of up to two million
shares of preferred stock, which conceivably would represent an additional class
of stock required to approve any proposed acquisition. This preferred stock,
none of which has been issued, together with authorized but unissued shares of
the common stock could represent additional capital required to be purchased by
the acquiror. Bank Mutual's charter authorizes the issuance of up to 100 million
shares of the common stock.

         In addition to discouraging a takeover attempt which a majority of our
shareholders might determine to be in their best interest or in which our
shareholders might receive a premium over the current market prices for their
shares, the effect of these provisions may render the removal of our management
more difficult. It is possible that incumbent officers and directors might be
able to retain their positions (at least until their term of office expires)
even though a majority of our shareholders, other than the mutual holding
company, desires a change.

         The provisions described above are intended to reduce Bank Mutual's
vulnerability to takeover attempts and certain other transactions which have not
been negotiated with and approved by members of its board of directors. The
provisions of the employment agreements, the change of control agreements, the
management recognition plan and the stock option plan to be established may also
discourage takeover attempts by increasing the costs to be incurred by Bank
Mutual and its subsidiaries in the event of a takeover. See "Management --
Employment Agreements," and "-- Future Stock Benefit Plans -- Stock Option
Plan."

         Bank Mutual's board of directors believes that the provisions of the
charter, bylaws and benefit plans to be established are in the best interests of
Bank Mutual and its shareholders. An unsolicited non-negotiated proposal can
seriously disrupt the business and management of a corporation and cause it
great expense. Accordingly, the board of directors believes it is in the best
interests of Bank Mutual and its shareholders to encourage potential acquirors
to negotiate directly with management and that these provisions will encourage
such negotiations and discourage non-negotiated takeover attempts. It is also
the board of directors' view that these provisions should not discourage persons
from proposing a merger or other transaction at a price that reflects the true
value of Mutual and that otherwise is in the best interests of all shareholders.


                   DESCRIPTION OF CAPITAL STOCK OF BANK MUTUAL

         Bank Mutual is authorized to issue 100 million shares of common stock,
par value $.01 per share, and ten million shares of preferred stock, $.01 par
value per share. We currently expect to issue between 19.6 million and 27.6
million shares of common stock in the restructuring and the First Northern
merger, including between 9.8 million and 13.8 million shares to persons other
than the MHC. See "Capitalization."

         Upon payment of the purchase price, shares of common stock issued in
the offering will be fully paid and non-assessable. Under the Wisconsin
Business Corporation Law, shareholders of Wisconsin-chartered corporations


                                     -137-
<PAGE>   140


are liable for claims to employees for services, not to exceed six months
services in any one case, up to the consideration which they have paid for their
shares of common stock. The Wisconsin Supreme Court has applied this statute to
corporations which are not organized in Wisconsin but are qualified to do
business in the state. While Bank Mutual believes that these provisions may not
necessarily apply to federally-chartered entities, there has not been a judicial
determination of that result.

NO PREEMPTIVE RIGHTS

         The holders of Bank Mutual common stock do not have any preemptive
rights with respect to any shares issued by the company. Any subsequent stock
issuance by Bank Mutual, however, may only be effected through a stock issuance
plan approved by the OTS which would grant subscription priorities to the MHC's
members unless Bank Mutual demonstrates that a non-conforming stock issuance
would be more beneficial to it.

LIQUIDATION RIGHTS; REDEMPTION

         In the event of any liquidation, dissolution or winding up of Bank
Mutual, the holders of its common stock generally would be entitled to receive,
after payment of all liabilities and any preferred stock preferences, all assets
of Bank Mutual available for distribution. Common stock is not subject to any
redemption provisions.

TREATMENT UPON FULL CONVERSION

         In the event that Mutual would make a full conversion of the MHC to the
stock form of organization, the plan of restructuring includes provisions
intended to protect Bank Mutual shareholders. In general, they provide that Bank
Mutual shareholders would receive, in any subsequent full conversion, the same
percentage of ownership of a successor entity as they would hold in Bank Mutual
prior to that conversion. See "The Restructuring and the Offering - Possible
Conversion of the MHC to Stock Form."

         Bank Mutual cannot assure that there will be a subsequent full
conversion. Also, any such full conversion will be subject to OTS, or other
governmental regulations as then in effect. Those regulations may affect the
treatment of Bank Mutual shareholders in any full conversion, and could have the
effect of disadvantaging Bank Mutual shareholders.

VOTING RIGHTS

         Holders of Bank Mutual common stock will have one vote for each share
held by them on all matters which are presented to a shareholders' vote. There
is an exception to this rule during the first five years of Bank Mutual's
existence for persons or entities (other than the MHC) which come to acquire
more than 10% of Bank Mutual's common stock. In that case, shares in excess of
10% of Bank Mutual's outstanding common stock will not have any voting rights.
See "Restrictions on Acquisition of Bank Mutual -- Bank Mutual's Charter and
Bylaws."

         Bank Mutual's shareholders do not have cumulative rights in the
election of directors. Because the MHC will always own more than 50% of the
voting shares of Bank Mutual, it will control the election of directors.

BOARD OF DIRECTORS

         The Bank Mutual charter and bylaws provide that its board of directors
shall consist of not less than 5 no more than 15 directors, and determined from
time to time by the board of directors. The directors are classified into three
classes, which are to be as nearly equal in size as possible. Each class is
elected for a three-year term, and one of the classes of the board of directors
is subject to election at each annual meeting of Bank Mutual shareholders.


                                     -138-
<PAGE>   141

         The Bank Mutual bylaws also provide that a director may be removed only
for cause by a vote of the holders of majority of shares entitled to vote.

         Vacancies on the Bank Mutual board of directors, whether by resignation
of a director or by the establishment of an increase in the number of directors,
may be filled by action of the remaining directors of Bank Mutual. However, the
directors so elected only serve until the next meeting of shareholders.

         Directors of Bank Mutual must own not less than 100 shares of Bank
Mutual common stock.

SPECIAL MEETINGS OF SHAREHOLDERS

         Under Bank Mutual's charter, until five years after the restructuring,
special meetings of shareholders of Bank Mutual may only be called upon the
direction of the board of directors. Thereafter, special meetings may be called
by the chairman, the president and majority of the directors, or upon the
written request of holders of not less than 10% of all the outstanding shares of
capital stock.

         The Bank Mutual board of directors will act as a nominating committee
for the selecting of management nominees for election of directors. With certain
exceptions in the case of vacancies, nominating committee must deliver written
nominations to the secretary at least 20 days prior to the date of the annual
meeting. No nominations for directors except for those made by the nominating
committee will be voted upon at the annual meeting unless other nominations by
shareholders are made in writing and delivered to Bank Mutual at least five days
prior to the date of the annual meeting.

PREFERRED STOCK

         The Bank Mutual charter authorizes the issuance of preferred stock, in
one or more classes with the rights and preferences of shareholders of those
classes to be determined by the board of directors. If the company were to issue
shares of preferred stock, their holders would have dividend and liquidation
rights prior to those holders of common stock, and would have such voting rights
as were determined by the board of directors.

APPROVAL OF FUNDAMENTAL TRANSACTIONS

         Corporate combination transactions such as mergers, sales of
substantially all assets, or dissolution of the corporation, would require the
approval of the holders of a majority of the outstanding shares of Bank Mutual
common stock. Because the MHC would own a majority, it would control all the
decisions on these matters. Similarly, the approval of the majority of
outstanding shares is required for an amendment to the Bank Mutual certificate
of incorporation. In the event Mutual had issued shares of preferred stock,
preferred shareholders may have rights to vote as a class on certain types of
amendments.

DISSENTERS' RIGHTS

         Because Bank Mutual has provided that it will be subject to Wisconsin
corporate law provisions, so long as Bank Mutual has a class of securities
traded on the NASDAQ Stock Market or an exchange, its shareholders will not have
dissenters' rights in most corporate transactions.


                             LEGAL AND TAX OPINIONS

         The legality of the issuance of the common stock being offered and
certain matters relating to the restructuring and federal taxation will be
passed upon for us by Quarles & Brady LLP, Milwaukee, Wisconsin.

                         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.

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. Significant intercompany accounts and
transactions have been eliminated in consolidation.

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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

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 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.

MORTGAGE SERVICING RIGHTS

Mortgage servicing rights are recorded as an asset when loans are sold with
servicing rights retained. The cost of mortgage servicing rights is amortized in
proportion to, and over the period of, estimated net servicing revenues.
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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

INTEREST AND FEES ON LOANS

Allowances of $214 (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 March 31, 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 specific and general valuation
allowances. The Bank establishes specific valuation allowances on loans it
considers to be impaired. A loan is considered impaired when the carrying amount
of the loan exceeds the present value of the expected future cash flows,
discounted at the loan's original effective interest rate, or the fair value of
the underlying collateral. A specific valuation allowance is established for an
amount equal to the impairment. 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. Management may transfer amounts between specific
and general valuation allowances as considered necessary. The allowance reflects
management's best estimate of the amount necessary to provide for the impairment
of loans, as well as other 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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

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. Gains on sales are
recognized based on the carrying value when the earnings process is
substantially complete. Losses on sales not previously provided for are
recognized upon closing of the sale.

PREMISES AND EQUIPMENT

Land, buildings, leasehold improvements and equipment are carried at amortized
cost. Buildings and equipment are depreciated over their estimated useful lives
using the straight-line method. Leasehold improvements are amortized over the
shorter of their useful lives or lease terms. 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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

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.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

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 $235 (unaudited) and $678
(unaudited) for the three-month periods ended March 31, 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 $11,261,
(unaudited) $11,496 and $29,786 at March 31, 2000, and December 31, 1999 and

              (Information with respect to March 31, 2000 and the
        three-month periods ended March 31, 2000 and 1999 is unaudited)


9. BORROWINGS (CONTINUED)

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 $13,537 at March 31, 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 March 31, 2000 and
December 31, 1999, that the Bank meets all capital adequacy requirements to
which it is subject.

10. EQUITY (CONTINUED)

As of March 31, 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 $21 (unaudited) and $19 (unaudited) in the three months ended
March 31, 2000 and 1999, and $68 in 1999 and $56 in 1998.

11. EMPLOYEE BENEFIT PLANS (CONTINUED)

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
employment. The Bank's funding policy is to contribute annually the amount
necessary to satisfy the requirements of the Employee Retirement Income Security
Act of 1974.

Plan assets which consist primarily of immediate participation guarantee
contracts with an insurance company are actively managed by investment
professionals.

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 $264 (unaudited) and $266 (unaudited) in
the three months ended March 31, 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.

For state income tax purposes, the subsidiaries of the Bank have net business
loss carryovers of $487 available to offset against future income which expire
through 2013.

The income tax provision differs from the provision computed at the federal
statutory corporate rate for three months ended March 31, 2000 and 1999 and the
years ended December 31, 1999, 1998 and 1997 follows:

12. INCOME TAXES (CONTINUED)

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. The significant
components of the Bank's deferred tax assets and liabilities as of March 31,
2000 and December 31, are summarized as follows:

</TABLE>

The Bank qualified under provisions of the Internal Revenue Code that permitted
it to deduct from taxable income an allowance for bad debts that differed from
the provision for such losses charged to income for financial reporting
purposes. Accordingly, no provision for federal income taxes has been made for
approximately $48,592 of retained income as of March 31, 2000 (unaudited) and
December 31, 1999. If, in the future, the Bank no longer qualifies as a bank for
tax purposes, income taxes of approximately $19,500 would be imposed.

13. CONTINGENT LIABILITY

The Bank has entered into an agreement whereby, for an initial fee and annual
fee, certain of its United States Treasury notes are pledged as collateral for
an Industrial Development Revenue Bond which was issued by a local municipality
to finance commercial real estate owned by a third party, unrelated to the Bank.
Under the terms of the agreement, the Bank must maintain with a trustee
collateral with a fair market value, as defined, aggregating 128%, 135% and 135%
or more of the sum of the outstanding principal balance of the bonds plus
accrued interest on the outstanding principal at March 31, 2000 and December 31,
1999 and 1998, respectively. The Bank continues to receive interest payments on
the collateral.

At March 31, 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 March
31, 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.

   Adjustable rate                                                12,184          7,595          4,003
</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 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 $147 (unaudited), $0 and $17,030
at March 31, 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.

                                      F-34

<PAGE>   179

                     Mutual Savings Bank and Subsidiaries

            Notes to Consolidated Financial Statements (continued)

              (Information with respect to March 31, 2000 and the
        three-month periods ended March 31, 2000 and 1999 is unaudited)


15. FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

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 oneto 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.

15. FAIR VALUE OF FINANCIAL INSTRUMENTS (CONTINUED)

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

16. MERGER AND CONVERSION (CONTINUED)

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 March
31, 2000 (unaudited) and December 31, 1999, no 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.

16. MERGER AND CONVERSION (CONTINUED)

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.

                                      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.

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 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 economic life
          of the improvements.


                                                                          FN-10

NOTE 1    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

          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.

The Company is a Treasury Tax & Loan (TT&L) depository for the Federal Reserve
Bank (FRB), and as such, it accepts TT&L deposits. The Company is 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.

At December 31, 1999, the Company had an irrevocable letter of credit
outstanding with the FHLB for $725,000. This letter of credit is pledged against
a municipal deposit with the Company. No amounts have been drawn against the
letter of credit by the Company.

NOTE 9    EMPLOYEE BENEFIT PLANS

          The Company has a participatory defined contribution 401(k) plan. The
          plan covers all employees with at least one year of service and who
          have attained age 21. The Company annually contributes 3% of an
          employee's gross earnings and may fund an additional discretionary
          dollar amount to the plan. The Company also 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 (SARSs), 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.


                                                                           FN-20

NOTE 9    EMPLOYEE BENEFIT PLANS (Continued)

          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:

          <TABLE>

          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 (Continued)

          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.

NOTE 13   SEGMENT INFORMATION

          First Northern Capital Corp., through a branch network of its
          subsidiary, First Northern Savings Bank, provides a full range of
          consumer and commercial financial institution services to individuals
          and businesses in Northeastern Wisconsin. These services include
          demand, time, and savings deposits; safe deposit services; credit
          cards; notary services; night depository; money orders, traveler's
          checks, and cashier's checks; savings bonds; secured and unsecured
          consumer, commercial, and real estate loans; ATM processing; cash
          management; and financial planning.

          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:

</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.


                                                                           FN-26

NOTE 14   COMMITMENTS (Continued)

          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 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.


                                                                           FN-27

</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 in the estimates.

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 share 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.


                                                                           FN-32

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

OVERVIEW
         First Northern Capital Corp.  (the "Company" or "First Northern") is a
unitary savings and loan holding company, of which First Northern Savings Bank,
S.A. (the "Savings Bank"), a Wisconsin chartered capital stock savings and loan
association, is a wholly owned subsidiary.

         The Savings Bank was reorganized into First Northern on December 20,
1995, with each outstanding share of the Savings Bank's common stock converted
into one share of the Company's common stock (the "Reorganization").
Consequently, the holders of all the outstanding stock of the Savings Bank
acquired the same proportionate ownership interest in First Northern as they had
held in the Savings Bank. The consolidated capital, assets, liabilities, income
and other financial data of First Northern immediately following the
Reorganization were substantially the same as those of the Savings Bank
immediately prior to consummation of the Reorganization.

         The Savings Bank is the only direct subsidiary of the Company and its
operations are the primary contributor to the Company's earnings and expenses.
The Savings Bank's business consists primarily of attracting deposits from the
general public and originating loans throughout its Northeastern Wisconsin
branch network. Great Northern Financial Services Corporation ("GNFSC"), a
wholly owned subsidiary of the Savings Bank, offers full brokerage services to
the public through a network agreement with a registered broker-dealer and sells
tax deferred annuities, credit life and disability insurance. Another wholly
owned Savings Bank subsidiary, First Northern Investments, Inc. ("FNII"),
manages a majority of the Savings Bank's investments, purchases automobile loans
from Savings Financial Corp. ("SFC") and mortgage loan participations from its
parent. SFC, which is 50% owned by the Savings Bank, originates, services and
sells automobile loans to FNII and its other parent corporation.

         In connection with the following discussion, see the financial data in
Item 1 and "Cautionary Factors" in Item 1 of this document regarding
forward-looking statements and factors that could impact the business and
financial prospects of the Company.

MERGER AGREEMENT
         On February 21, 2000, First Northern entered into a Merger Agreement
with Mutual Savings Bank which provides for the acquisition of First Northern by
Mutual. See Item 1. "Business--Merger Agreement with Mutual Saving Bank.", which
is incorporated by reference herein.

BALANCE SHEET ANALYSIS
LIQUIDITY. The Company's primary sources of funds are deposits (retail and
wholesale), proceeds from principal and interest payments on loans, advances
from the Federal Home Loan Bank (the "FHLB") of Chicago, and, to a lesser
extent, maturities of investment securities and short-term investments, sales of
loans, repurchase agreements, and operations. While scheduled loan repayments
and maturing investments are a relatively predictable source of funds, deposit
flows and loan prepayments are influenced to a great extent by interest rates,
general economic conditions, and competition.

         Federal regulations historically have required First Northern to
maintain minimum levels of liquid assets such as cash, certain time deposits,
U.S. government and agency securities, and other obligations generally having
remaining maturities of less than five years. Liquidity requirements have varied
from time to time based upon economic conditions and deposit flows. The current
requirement is 4% of the preceding calendar month's average net withdrawable
deposits and borrowings payable on demand or in one year or less ("liquidity
base") or of the average daily balance of the liquidity base during the
preceding quarter. The Company's total liquidity ratio at December 31, 1999 was
5.45% and 5.49% at December 31, 1998. The liquidity ratio decreased at year-end
1999 as compared to year-end 1998 as a result of funding loan originations.

         Liquidity management is both a daily and long-term responsibility of
management. The Company adjusts its investments in liquid assets based upon
management's assessment of: (i) expected loan demand; (ii) expected deposit
flows; (iii) yields available on interest-earning deposits; and (iv) the
objectives of its asset/liability management program. Excess liquidity is
generally invested in interest-earning overnight deposits and short- to
intermediate-term U.S. Government and agency obligations. If the Savings Bank
requires funds beyond its ability to generate them from operations, it can
borrow from the FHLB of Chicago (See "Borrowings").

                                                                           FN-33
<PAGE>   217

INVESTMENT AND MORTGAGE-RELATED SECURITIES. A substantial portion of the
Company's investment securities (approximately $32.4 million at December 31,
1999 and $33.3 million at December 31, 1998) are held and managed by FNII. (See
Notes to Consolidated Financial Statements -- Note 2 and Note 3 -- Securities
Available-for-Sale and Securities Held-to-Maturity.)

         Interest-earning deposits increased $3.5 million in 1999 as a result of
placing excess funds in overnight deposits until the funds (usually a day) are
needed.

         The securities available-for-sale increased to $14.0 million at
December 31, 1999, from $10.2 million at December 31, 1998. The increase in 1999
is the result of reinvesting interest earned on the investments held in
available-for-sale into additional securities and the purchasing of additional
mortgage-related securities. First Northern purchases mortgage-backed and
mortgage-related securities that are guaranteed by government sponsored
enterprises such as FHLMC, FNMA and GNMA.

         The securities held-to-maturity increased to $36.3 million at December
31, 1999 from $35.3 million at December 31, 1998, as a result of reinvesting
interest earned on the investments held-to-maturity.

LENDING ACTIVITIES. First Northern has traditionally concentrated on the
origination of adjustable and fixed interest rate one- to four-family mortgage
loans and consumer loans throughout its 19 offices. First Northern also
originates construction, more than four-family ("multi-family") residential,
commercial real estate loans and beginning in 1999, commercial loans. In
addition, the Savings Bank will purchase one- to four-family and multi-family
mortgage loans from other sources primarily within the State of Wisconsin.
Adjustable interest rate mortgage loans are originated for First Northern's
portfolio while fixed interest rate mortgage loans, particularly those with
terms greater than 20 years, are primarily originated for sale in the secondary
mortgage market. First Northern retains 15 and 20 year fixed interest rate
mortgage loan originations in its portfolio. At December 31, 1999, approximately
75% of First Northern's mortgage loan portfolio were interest rate adjustable as
compared to 76% at December 31, 1998.

         First Northern originates a variety of adjustable and fixed interest
rate mortgage loan products based upon market demands and general economic
conditions. Adjustable indexed interest rate mortgage loans at December 31,
1999, contain an interest rate adjustment provision tied to the national monthly
median cost of funds ratio for Savings Association Insurance Fund ("SAIF")
insured institutions, plus an additional mark-up of 2.95% to 4.25% (the "index")
which varies with the mortgage loan product. Interest rates on indexed mortgage
loans are adjusted, up or down, on predetermined dates fixed by contract, in
relation to and based on the index or market interest rates. In the first six
months of 1999, First Northern adjusted interest rates on indexed mortgage loans
downward at or before the contractual interest rate adjustment date in response
to decreasing market interest rates. If the adjustable indexed mortgage loans
interest rates had not been decreased, these mortgage loans would have
refinanced to a fixed interest rate mortgage loan or another indexed mortgage
loan at a lesser interest rate. In the second quarter of 1999, the increasing
market interest rates allowed First Northern to increase interest rates on
certain mortgage loans. In 1999, First Northern decreased interest rates on
approximately $28.0 million of its mortgage loans and increased interest rates
on approximately $43.0 million of its mortgage loans.

         Adjustable indexed interest rate mortgage loans have an initial period,
ranging from one to five years, during which the interest rate is fixed, with
adjustments permitted thereafter, subject to annual and lifetime interest rate
caps which vary with the product. Annual limits on interest rate increases are
1% to 2%, while aggregate lifetime interest rate increases over the term of the
loan are currently at 6% above the original mortgage loan interest rate.

         First Northern's origination of second mortgage loans, automobile,
boat, recreational vehicle and other types of consumer loans, which are
generally of shorter maturities than first mortgage loans, enhances the matching
of maturities of its assets and liabilities and offer a higher yield. Second
mortgage loans are offered on both a fixed and adjustable interest rate basis;
other consumer loans are generally offered on a fixed interest rate basis.

         At December 31, 1999, approximately 23% and as of December 31, 1998,
approximately 35% of First Northern's consumer loan portfolio was interest rate
adjustable.

         First Northern added commercial lending to its existing product lines
in the second quarter of 1999. To manage the commercial banking department,
First Northern hired an experienced commercial loan manager. During 1999, $5.0
million of commercial loans were originated as well as $14.4 million of
commercial real state loans which are reported in the mortgage loan
originations.

</TABLE>

         The dollar volume of First Northern's mortgage loan originations and
purchases decreased in 1999 as compared to 1998 primarily as a result of a
decline in the mortgage loan refinancing activity. In addition, First Northern
continued to purchase mortgage loans in 1999 primarily from other Wisconsin
financial institutions. In 1999, First Northern purchased $31.9 million of one-
to four-family residential loans, $1.5 million of multi-family loans and $3.5
million of commercial real estate loans as compared to $15.0 million of one- to
four-family residential, $1.7 million of multi-family and $0.6 million of
commercial real estate loans in 1998. First Northern purchases loans when
interest rates on these loans provide an opportunity to incrementally add to the
profitability of the Company.

         First Northern's growth in the dollar amount of mortgage loans
outstanding was $70.1 million or 14.3% for 1999 as compared to $38.7 million or
8.6% in 1998. The increase in the 1999 mortgage loan portfolio was the result of
more adjustable interest rate mortgage loan originations which are retained in
the portfolio, as opposed to 30 year fixed interest rate mortgage loan
originations which are sold in the secondary market, and reduced mortgage loan
refinancings.

         At December 31, 1999, First Northern had approximately $140.2 million
fixed interest rate mortgage loans in its mortgage loan portfolio, compared to
approximately $116.0 million of fixed interest rate mortgage loans at December
31, 1998.

         In 1999, First Northern sold $20.1 million of fixed interest rate
mortgage loans as compared to $63.2 million in 1998. This decrease was the
result of increasing interest rates on fixed interest rate mortgage loans and a
shift in consumer preference toward adjustable interest rate mortgage loans.

         The consumer loan portfolio at December 31, 1999, increased $36.4
million as compared to December 31, 1998 as a result of increased consumer loan
originations and purchases. The increase in consumer loan originations of $33.0
million was the result of increased second mortgage loan originations and an
increase in the dollar amount of loan purchases from SFC. In 1999, First
Northern and FNII purchased $63.7 million of automobile loans from SFC as
compared to $40.9 million in 1998. This increase in purchases from SFC was the
result of continued growth in the indirect automobile loan market. SFC
originates indirect automobile loans in the State of Wisconsin and sells these
loans to the Savings Bank or FNII and the other SFC shareholder while retaining
the servicing of such loans.

</TABLE>


         Total non-performing loans and assets increased in dollar amount in
1999 as compared to 1998, but decreased as a percentage of total loans. This low
level of non-performing loans, as compared to state and national averages, was
the result of the stable economy in First Northern's market areas and
management's continued emphasis to maintain non-performing assets at low levels.

         Management also believes that allowances for losses on loans, real
estate owned and repossessed assets are adequate. While management uses
available information to recognize losses on loans, real estate owned and
repossessed assets, future additions to the allowances may be necessary based on
changes in economic conditions or regulatory requirements.

         A summary of the general loan loss allowances is shown below:

LIFE INSURANCE POLICIES. Life insurance policies or bank owned life insurance
("BOLI") increased $1.0 million in 1999 primarily as a result of the increased
value. BOLI is long-term life insurance on the lives of certain current and past
Savings Bank employees where the insurance policy benefits and ownership are
retained by the Savings Bank. The cash value accumulation on BOLI is permanently
tax deferred if the policy is held to the participant's death. Management
believes this is an effective method to help offset a portion of future employee
benefit costs.

DEPOSITS. Deposits increased $24.5 million or 4.5% in 1999 as compared to $60.6
million or 12.6% in 1998. Deposit growth moderated in 1999 primarily as a result
of the investment returns on competing investments in which consumers placed
their funds. As of December 31, 1999 deposits totaled $566.9 million or 74.3% of
total liabilities.

         First Northern experienced modest deposit growth in 1999 as a result
of; (i) Northeastern Wisconsin continuing to have good economic growth which has
created new customers; and (ii) the utilization of wholesale and jumbo deposits.
Competition for retail deposits in First Northern's market area has been and
will continue to be very strong.

         First Northern establishes savings deposit interest rates to be
competitive in each market area and to maintain a favorable interest rate
spread. The deposit acquisition philosophy continues to be that an increase in
deposit dollars will be sought only if the increase is incrementally profitable.

         Due to competition for retail deposits, First Northern will continue to
seek alternative sources of funding, including wholesale and jumbo ($90,000 or
more) deposits. At December 31, 1999, First Northern had a total of $53.2
million of wholesale brokered, corporate and municipal jumbo deposits as
compared to $32.1 million at the end of 1998. Jumbo and wholesale deposits
accounted for 86% of the deposit increase for 1999 and at times, were obtained
at a slightly lower cost than retail deposits. This strategy of acquiring
wholesale and jumbo deposits continues to be an integral part of the Savings
Bank's deposit acquisition strategy for 2000.

         First Northern established an internet site (www.firstnorthern.com) in
1999 and utilized other websites to publicize deposit interest rates. Management
believes the website aided in the acquisition of jumbo deposits. The First
Northern website is anticipated to develop into another distribution channel for
First Northern products and services in the year 2000 and beyond.

         First Northern believes that the household checking account is the
basic account upon which further customer banking relationships can be
developed. First Northern utilized aggressive pricing and marketing of the
checking account and has been able to become the "primary financial institution"
for many households. First Northern will continue to emphasize the number of
households using First Northern's checking account services which is anticipated
to increase associated non-interest fee income.

         To enhance this checking account relationship and to increase
non-interest fee income, First Northern continued to expand its First Northern
CheckCard (Debit Card) base. The First Northern CheckCard offers a checking
account customer the opportunity to access a checking account anywhere in the
world where VISA is accepted. First Northern aggressively marketed the First
Northern CheckCard since 1997 and as a result of this aggressive marketing
philosophy, the CheckCard has gained greater customer acceptance and increased
product profitability.

         New deposit opportunities will be available as a result of the addition
of the Commercial Banking Department in 1999. Efforts to obtain commercial
checking and other commercial investments from new and existing commercial
customers will be an area of emphasis for First Northern.

         The Taxpayers Relief Act of 1997 continues to offer investors and
homeowners significant tax planning opportunities ranging from income tax
savings, estate tax savings, lower capital gains rates, retirement and education
benefits, and the elimination of certain taxes altogether. Although First
Northern had anticipated that the new Roth and Education Individual Retirement
Account would result in higher deposit growth, First Northern did not experience
a significant deposit growth in these retirement accounts for the second
straight year. Educational efforts will continue to be made to communicate the
advantages of the Roth and Education Individual Retirement Accounts to existing
and potential customers.

         The GNFSC Investment Center, established in April, 1995, posted a fifth
straight year of profitability. Profits for 1999 were a record for the
Investment Center. The Investment Center offers non-insured deposit products,
such as fixed and variable tax-deferred annuities, stocks, mutual funds and
brokerage products through a network agreement with a registered broker-dealer.



                                                                           FN-37




<PAGE>   221


The establishment of the Investment Center has resulted in increased customer
retention and new customer relationships through the existing Savings Bank's
branch network.

         First Northern's objective is to create a one-stop family financial
banking center by offering a wide selection of checking accounts, short,
intermediate and long-term certificates of deposit, insured retirement accounts,
mutual funds, other investments and mortgage and consumer loans to meet a wide
variety of customer needs.

BORROWINGS. Borrowings, primarily from the FHLB of Chicago, increased $93.9
million at December 31, 1999, as compared to December 31, 1998, as a result of
the Savings Bank's loan growth and modest deposit growth. The borrowings have
maturities ranging from overnight to approximately nine years (See Notes to
Consolidated Financial Statements -- Note 7-Borrowings). Management anticipates
it will continue to utilize borrowings to fund its growth in interest-earning
assets in 2000.

STOCKHOLDERS' EQUITY. First Northern's stockholders' equity to total assets
ratio at December 31, 1999, was 9.15%, as compared to 10.57% at December 31,
1998. First Northern employs methods which are intended to increase
interest-earning assets and thus reduce the percentage of equity to total assets
(known as leveraging). In addition to interest-earning asset growth, the Company
has also repurchased its stock. The first stock repurchase program, which began
in March of 1996 and was completed in September 1996, resulted in the repurchase
of 456,934 shares at an average cost of $7.91 per share. A second stock
repurchase program which began in October 1996 authorized the repurchase of
438,114 shares. The second stock repurchase program repurchased 60,800 shares at
an average cost of $8.62 per share before it expired in October 1997. A third
stock repurchase program was implemented in March of 1998 which authorized the
repurchase of up to 446,101 shares. At December 31, 1999, all 446,101 shares
authorized to be repurchased were at an average cost of $11.81 per share. First
Northern may implement additional stock repurchase programs in the future if it
is determined to be economically prudent and with the consent of Mutual per the
Merger Agreement.

         The Wisconsin Department of Financial Institutions--Division of Savings
Institutions, which regulates the Savings Bank, requires maintenance of a
minimum of six percent equity to total assets. In addition, the Office of Thrift
Supervision ("OTS") capital rules require the Savings Bank to meet certain
capital standards: (i) tier I (core) capital to risk-weighted assets; (ii)
risk-based capital to risk-weighted assets; and (iii) tier I (core) capital to
adjusted assets. The Savings Bank meets and exceeds all regulatory capital
standards (See Notes to Consolidated Financial Statements--Note
10--Stockholders' Equity).

ASSET AND LIABILITY MANAGEMENT

         The primary function of asset and liability management is to provide
liquidity and maintain an appropriate balance between interest-earning assets
and interest-bearing liabilities. Interest rate risk is the imbalance between
interest-earning assets and interest-bearing liabilities at a given maturity or
repricing date and is commonly referred to as the interest rate gap (the "gap").
A positive gap exists when there are more assets than liabilities maturing or
repricing within the same time frame. A negative gap occurs when there are more
liabilities than assets maturing or repricing within the same time frame. The
following chart reflects First Northern's gap position as of December 31, 1999:

(1)      Excludes undisbursed loan proceeds of $17,852.
(2)      Includes $1,085 of education loans held for sale.

(4)      Excludes unrealized gains or losses.
(5)      Does not include accrued interest, which totals $2,823 for all
         deposits.

         The calculation of a gap position is subjective by nature and requires
management to make a number of assumptions as to when an asset or liability will
reprice or mature. Assumptions used in estimating the maturity/repricing amounts
and dates of the more significant asset and liability categories include: (i)
investment securities - based upon contractual maturities and if applicable,
call dates; (ii) loans - based upon contractual maturities, repricing date, if
applicable, scheduled repayments of principal and projected prepayments of
principal based upon the Company's historical experience; (iii) mortgage-related
securities based upon an average of Wall Street estimates for prepayment speeds;
and (iv) deposits based upon contractual maturities and various decay rates
applied to the remaining deposit dollars. The decay rate, which varies with
deposit product, is based on historical decay rates of First Northern.




                                                                           FN-39

         First Northern's overall asset and liability management goal is to
maximize long-term profitability and returns to stockholders. First Northern's
current strategy is to: (i) originate and retain adjustable interest rate
mortgage loans; (ii) originate and retain 15 and 20 year fixed interest rate
mortgage loans; (iii) originate and sell most 30 year fixed interest rate
mortgage loans; (iv) originate shorter maturity consumer loans; (v) emphasize
the origination of adjustable interest rate home equity loans; (vi) counsel
depositors to balance their deposits between short-, intermediate-, and
long-term deposits; and (vii) offer new and attractive deposits and investment
opportunities. In addition, borrowings with various terms are used to reach the
targeted asset/liability mix. Currently, management's strategic goal for
asset/liability management is to maintain a cumulative one (1) year gap within a
range of a positive 10% to a negative 20%. Management believes this is an
appropriate level to achieve First Northern's long-term goals, while controlling
interest rate risk.

IMPACT OF YEAR 2000

         First Northern did not experience any problems to its critical
operating systems on January 1, 2000. First Northern had tested and/or upgraded
its systems (such as software, hardware, telephones, voicemail, heating,
ventilating, air conditioners, alarms etc.) throughout 1999. The Company
anticipated that all modifications, upgrades or replacement of all systems would
not exceed $170,000 (pre-tax). At December 31, 1999, approximately $148,000
(pre-tax) had been spent. First Northern will continue to monitor its systems
during 2000.

GRAMM-LEACH-BLILEY ACT

         Management anticipates the Gramm-Leach-Bliley Act will not have a
significant impact on First Northern's operations in the near future; however,
management will continue to evaluate and look for opportunities as a result of
the Act and is unable to predict the impact on its operations at this time. See
Item 1. "Business--Regulation--Federal Regulation of Holding
Companies--Gramm-Leach-Bliley Act."

AVERAGE BALANCE SHEET AND YIELD/RATE ANALYSIS
         The following table presents, for the periods indicated, the total
dollar amount of interest income from average interest-earning assets, the
resultant yields, and the interest expense on average interest-bearing
liabilities, expressed both in dollars and rates. No tax equivalent adjustments
were made since First Northern does not have any tax exempt investments. Average
balances are derived from average daily balances. The yield on securities
available-for-sale are included in investment securities and mortgage-related
securities and yields are calculated on the historical basis. The yields and
rates are established by dividing income or expense dollars by the average
balance of the asset or liability.

RATE VOLUME ANALYSIS OF NET INTEREST INCOME
          The interaction of changes in volume and rates earned or paid with
regard to interest-earning assets and interest-bearing liabilities has a
significant impact on net income between periods. The volume of interest-earning
dollars in loans and investments compared to the volume of interest-bearing
dollars in deposits and borrowings, combined with the interest rate spread,
produces the changes in net interest income between periods.

          Information in the table below is provided in each category with
respect to (i) changes attributable to rate (changes in rate multiplied by prior
volume), (ii) changes attributable to volume (changes in volume multiplied by
prior rate, and (iii) changes attributable to changes in rate/volume (changes in
rate multiplied by changes in volume). Changes attributable to the combined
impact of volume and rate have been allocated proportionately to the changes due
to volume and the changes due to rate.

RESULTS OF OPERATIONS

COMPARISON OF YEARS ENDED DECEMBER 31, 1999 AND 1998.

GENERAL. Net income increased $548,000 in 1999 primarily as a result of an
increase in interest-earning assets and a reduction in the effective income tax
rate. Offsetting some of the increase in net income was a reduction of the gains
on the sales of loans and a compression of the net interest margin. The net
interest margin decreased as a result of the cost of new deposits and maturing
deposits increasing faster than the interest earned on the loan portfolio.

INTEREST INCOME. Interest income on mortgage loans increased $1.7 million as a
result of increased dollars outstanding in the mortgage portfolio. The average
mortgage loan portfolio increased $43.1 million in 1999. The average interest
rate decreased in 1999 to 7.03% from 7.33% in 1998 primarily as the result of:
(i) mortgage loans being originated at interest rates below the existing
mortgage loan yield and (ii) downward interest rate adjustments to qualified
interest rate adjustable mortgage loans in the first six months of 1999. As
market interest rates increased, mortgage loan originations in the fourth
quarter of 1999 equaled or exceeded the yield on the mortgage loan portfolio and
in the third and fourth quarter of 1999 interest rates on qualified adjustable
interest rate mortgage loans were increased.

         Interest income on consumer loans increased $543,000 as a result of an
increase in the average portfolio of $14.9 million. The average interest rate on
the consumer loan portfolio decreased to 7.87% in 1999 as compared to 8.26% in
1998 as a result of consumer loan originations being at interest rates below the
yield on the consumer loan portfolio. Consumer loan origination interest rates
exceeded the yield on the consumer loan portfolio beginning in the second half
of 1999.

         Interest income on commercial loans was $468,000. The commercial loan
portfolio had an average portfolio yield of 8.58% in 1999. First Northern began
originating commercial loans late in the second quarter of 1999.

         Investment securities and mortgage-related interest income increased in
1999 as a result of increased dollars outstanding. First Northern purchases
investment securities and mortgage-related securities when it incrementally adds
to the overall profitability of the Company or to aid in its interest rate risk
management.

         Interest-earning deposit interest income decreased $65,000 in 1999
primarily as the result of decreased interest-earning deposits outstanding.

INTEREST EXPENSE. Interest on deposits increased $289,000 in 1999 as a result of
increased deposits. Average deposits increased $44.2 million and the average
cost of deposits decreased to 4.26% in 1999 from 4.57% in 1998. First Northern
continued to utilize wholesale deposits in 1999 as a method to acquire deposits.
There are times when wholesale deposits are a more cost effective method to
acquire funds than retail deposits or borrowings.

         Borrowings continued to increase in 1999 and as a result, the interest
expense on borrowings increased $1.4 million. The increases in interest-earning
assets in 1999 and the modest growth in deposits necessitated the increase in
borrowings. It is anticipated by the Company that borrowings will continue to be
utilized throughout 2000 to fund its growth in interest-earning assets. First
Northern primarily borrows from the FHLB of Chicago.

         Advance payments by borrowers for taxes and insurance ("escrow")
interest expense increased in 1999 as a result of increased escrow dollars
outstanding. The escrow interest rate for 1999 was 2.74% as compared to 2.83%
for 1998. The escrow interest rate for 2000 will be 2.51%.

PROVISIONS FOR LOAN LOSSES. The provision for loan losses increased $52,000 in
1999 primarily as a result of the growth in the loan portfolio and the
composition of the loan portfolio specifically, the addition of commercial
loans. The total loan loss allowance at December 31, 1999, is $3,910,000 or .53%
of the total loan portfolio at December 31, 1999, as compared to $3,531,000 or
.56% of the total loan portfolio at December 31, 1998.

OTHER INCOME. Fees on serviced loans increased $12,000 primarily as a result of
the increased dollar amount of serviced loans and a reduction in the dollar
amount of mortgage loan prepayments. At December 31, 1999, First Northern
serviced $151.4 million in loans as compared to $150.2 million at the end of
1998. As the principal of a mortgage loan which was sold with servicing retained
prepays or repays, the mortgage servicing asset is reduced and netted against
the fees on serviced loans thereby reducing the income on serviced loans. As
mortgage loan repayments or prepayments decrease, the reduction to the mortgage
servicing asset is reduced as well as the reduction to the income on serviced
loans.





                                                                           FN-44

         Loan fees and service charges income decreased $32,000 as a result of
decreased Wisconsin Housing and Economic Development Authority ("WHEDA") loans
originations. First Northern originates mortgage loans for WHEDA and receives a
fee for each origination. During 1999 the dollar amount of WHEDA originations
decreased as a result of lack of consumer demand for the product.

         Deposit account service charges increased $114,000 primarily as the
result of: (i) the increased number of NOW(checking) accounts and their
associated fees; and (ii) customer usage of the CheckCard. CheckCard is a debit
card where each time the Savings Bank's CheckCard is used a fee, which varies
with each merchant, is paid to the Savings Bank by the debit card company. The
Savings Bank promotes the use of its debit card by direct mail and internal
promotions.

         Insurance commissions increased $37,000 primarily as a result of
increased bonuses received from insurance carriers. First Northern attained a
pre-determined threshold of insurance sales and insurance losses were below
another threshold thereby earning approximately $85,700 in insurance bonuses in
1999. Insurance bonuses in 1998 were $0.

         Gains on the sales of loans decreased $662,000 as a result of reduced
mortgage loan sales. The Savings Bank sold $20.1 million of mortgage loans in
1999 as compared to $63.2 million in 1998. (See Financial Condition--Balance
Sheet--Lending Activities)

         Other non-interest income increased $155,000 primarily as the result of
life insurance owned by First Northern. First Northern purchased life insurance
to partially offset the future cost of employee or director benefits. Interest
earned on life insurance in 1999 was $714,000.

OPERATING EXPENSES: Compensation expense increased $78,000 as a result of salary
and benefit costs increases and the 1998 increased accruals for the director
deferred retirement plan and supplemental executive retirement plan.

         Federal deposit insurance premiums increased $20,000 as a result of
increased deposits.

         Occupancy expense increased $119,000 as a result of the Savings Bank's
rental of approximately 14,000 square feet of additional office space in
downtown Green Bay, which began in the third quarter of 1999. First Northern
consolidated several of its back office support departments that had been
located in three separate First Northern locations as a result of the growth in
these areas.

         Data Processing expense increased $140,000 as the result of: (i)
accelerated depreciation of $45,000 on personal computers ("PCs"); (ii)
increased cost associated with First Northern's service bureau; (iii)
depreciation of new teller software; and (iv) cost of data processing supplies.

         Furniture and equipment expense decreased $50,000 primarily as the
result of a decrease in the cost of furniture and equipment service contracts
and depreciation expense. Service contract expense was decreased as a result of
eliminating individual service contracts and placing certain furniture and
equipment under an insurance service agreement. Depreciation expense was
decreased as a result of certain furniture and equipment that became fully
depreciated.

         Marketing expense increased $66,000 to promote loan and deposit
products. First Northern believes that growth in lending and deposits volumes is
facilitated by increased marketing of those products.

         Other expenses increased $127,000 as a result of increased costs
associated with the operations of SFC, costs associated with the operation of
the debit card and the reversal by the Petroleum Environmental Clean-up Fund of
a reimbursement, in the amount of $53,700, for environmental clean-up costs of a
lot at a subdivision owned by GNFSC. First Northern is presently appealing this
reversal.

INCOME TAXES. The effective income tax rate for 1999 was 32.3% as compared to
34.6% for 1998. The decrease in the effective income tax rate was the result of
the life insurance policies owned by First Northern and an increase in the
earnings of FNII, which is not subject to state income taxes. Since First
Northern intends to hold the life insurance until the participants' death, the
life insurance interest income is not taxable. In addition, First Northern moved
its indirect automobile loan portfolio to FNII at the beginning of the second
quarter of 1998, which has reduced state franchise taxes. In March 1999, First
Northern sold approximately $56.3 million in mortgage loan participations to
FNII to further reduce its state franchise tax.



                                                                          FN-45

COMPARISON OF YEARS ENDED DECEMBER 31, 1998 AND 1997.

GENERAL. Net income increased $793,000 in 1998 primarily as a result of the
dollar increase in interest-earning assets, gains from the sales of loans and a
reduction in the effective income tax rate.

INTEREST INCOME. Interest income on mortgage loans increased $2,067,000 as a
result of increased dollars outstanding in the mortgage loan portfolio. The
average interest rate earned decreased as a result of: (i) mortgage loans being
originated at interest rates below the existing mortgage loan portfolio yield;
(ii) downward interest rate adjustments to certain mortgage loans in its
portfolio before their scheduled adjustment dates in response to the refinancing
of existing adjustable interest rate mortgage loans; and (iii) the prepayments
of mortgage loans with higher than market interest rates.

         Interest income on consumer loans increased $744,000 as a result of an
increase of $12.1 million of consumer loans outstanding throughout 1998. The
average interest rate earned on the consumer portfolio decreased to 8.26% in
1998 as compared to 8.43% in 1997 as a result of: (i) consumer loan originations
at interest rates that were below the existing yield on the consumer loan
portfolio; (ii) decreases in some of First Northern's consumer loans which use
the prime interest rate as an index; and (iii) prepayments to consumer loans
that are at interest rates above market interest rates.

         Investment securities and interest-earning deposits interest income
increased $294,000 and $102,000 respectively, as a result of increased dollars
outstanding.

         The increase in the dollar amount of interest-earning deposits is the
result of excess funds above the funding needs for loans and operations, being
invested in short-term certificates of deposits or in overnight investments.
These additional funds were created by strong deposit gains and sales of loans.

         Interest on mortgage-related securities decreased $113,000 as a result
of prepayment and repayments to the underlying collateral (mortgage loans). The
average interest rate earned on mortgage-related securities decreased to 6.22%
from 6.36% primarily as the result of prepayments and repayments to higher than
market interest rate securities and the purchase of mortgage-related securities
at lower interest rates than existing yields on the mortgage-related securities
portfolio.

INTEREST EXPENSE. Interest expense on deposits increased $1,833,000 as a result
of increased deposits. First Northern utilizes various time deposit terms and
interest rates to attract new deposits and in 1998, utilized wholesale deposits
as a method to acquire less expensive deposits.

         Interest expense on borrowings increased $673,000 in 1998 primarily as
a result of increased average borrowings outstanding. First Northern primarily
borrows from the FHLB of Chicago.

         Advance payments by borrowers for taxes and insurance ("escrow")
interest expense increased modestly in 1998 as a result of the increased number
of escrow accounts that were interest-bearing. Although the interest rate paid
on escrow accounts of 2.83% was the same in 1998 as it was in 1997, and the
average dollars in escrow were approximately equal, a number of non
interest-bearing escrow accounts were replaced by interest-bearing escrow
accounts thus increasing interest expense. The escrow interest rate for 1999 is
2.74%.

PROVISIONS FOR LOAN LOSSES. First Northern provided an additional $420,000 to
loan loss allowances in 1998. The total loan loss allowance at December 31,
1998, is $3,531,000 or .56% of the total loan portfolio at December 31, 1998, as
compared to $3,177,000 or .53% of the total loan portfolio at December 31, 1997.

OTHER INCOME. Fees on serviced loans decreased $146,000 primarily as the result
of the amortization of the mortgage servicing asset in accordance with Financial
Accounting Standards (?FASB") No. 122, ?Accounting for Mortgage Servicing
Rights." As the principal of a mortgage loan which was sold with servicing
retained repays or prepays, the mortgage servicing asset is reduced and netted
against the fees on serviced loans, thereby reducing the income on serviced
loans. In 1998, the amortization of the mortgage loan servicing asset amounted
to $215,000 and $38,900 in 1997.

         Deposit account service charges increased $73,000 primarily as the
result of: (i) the increased number of NOW(checking) accounts and their
associated fees; and (ii) customer usage of CheckCard.

         Insurance commissions decreased $32,000 primarily as a result of a
reduction in the bonus received from insurance carriers.






                                                                           FN-46





<PAGE>   230

         Gains on the sales of loans increased $683,000 as a result of increased
loan sales. Loan sales in 1998 were $65.6 million as compared to $21.2 million
in 1997.

         Other non-interest income increased $359,000 primarily as the result of
BOLI. In December 1997, First Northern purchased $7.4 million of life insurance
to partially offset the future cost of employee benefits. Interest earned on the
$7.4 million of life insurance in 1998 was $396,000.

OPERATING EXPENSES. Compensation expense increased $538,000 as a result of
normal salary increases, the addition of 5 full-time equivalent employees and
increased accruals for the director deferred retirement plan and supplemental
executive retirement plan.

         Federal deposit insurance premiums increased $17,000 as a result of
increased deposits and in 1997, the receipt of a $15,000 refund of deposit
insurance premiums paid from prior periods.

         Data processing expense increased $73,000 primarily from increased
depreciation expense and service contract expense on data processing equipment.

         Furniture and equipment expense decreased $21,000 as a result of a
number of pieces of furniture and equipment being fully depreciated at the end
of 1997.

         Telephone and postage expenses decreased $33,000 by negotiating a
reduction to the cost of long distance calls and an increase in expense
deferrals associated with the substantial increase in loan originations.
Incremental telephone and postage expenses associated with loan originations are
deferred and amortized back against interest income over the life of the loan,
which results in an adjustment to the loan yield.

         Marketing expense increased $39,000 as a result of increased
advertising and marketing of deposit and loan products. First Northern believes
the growth in lending and deposit volumes is facilitated by increased marketing
of those products and hence, increased costs.

         Other expenses increased $96,000 as a result of increased costs
associated with the operations of SFC, costs associated with the issuance and
operations of the debit card and an increase in bad checks and customer fraud.

INCOME TAXES. The effective income tax rate for 1998 is 34.6% as compared to
37.7% for 1997. This decrease in the effective income tax rate is primarily the
result of earnings on BOLI for which no income tax provision is provided and the
increase in earnings at FNII which is not subject to state income taxes. Both
activities have reduced state franchise taxes.





                                                                           FN-47

BUSINESS

OVERVIEW. First Northern Capital Corp. (the "Company" or "First Northern"), a
unitary savings and loan holding company, was incorporated in Wisconsin in 1995
for the purpose of owning all of the outstanding stock of First Northern Savings
Bank, S.A. (the "Savings Bank"), a Wisconsin chartered capital stock savings and
loan association, which reorganized into the holding company structure effective
December 20, 1995 (the "Reorganization"). At that date, each outstanding share
of the Savings Bank's common stock was converted into one share of the Company's
common stock. Consequently, the former holders of all the outstanding stock of
the Savings Bank acquired the same proportionate ownership interest in First
Northern as they had held in the Savings Bank. The consolidated capitalization,
assets, liabilities, income and other financial data of First Northern
immediately following the Reorganization were substantially the same as those of
the Savings Bank immediately prior to consummation of the Reorganization. The
Reorganization was effected to provide greater flexibility in meeting the
Company's future financial and competitive needs. All data presented in this
10-K for dates and periods prior to December 20, 1995 relate to the Savings
Bank. All references herein to First Northern or the Company for any date or
period prior to consummation of the Reorganization shall be deemed to refer to
the Savings Bank.

    The Savings Bank is the only direct subsidiary of the Company and its
operations are the primary contributor to the Company's earnings and expenses.
The Savings Bank's business consists primarily of attracting deposits from the
general public and originating loans throughout its Northeastern Wisconsin
branch network. Great Northern Financial Services Corporation ("GNFSC"), a
wholly owned subsidiary of the Savings Bank, offers full brokerage services to
the public, including the sale of tax deferred annuities and mutual funds, and
sells credit life and disability insurance. Another wholly owned subsidiary,
First Northern Investments, Inc. ("FNII"), manages a majority of the Savings
Bank's investments and purchases automobile loans from Savings Financial
Corporation ("SFC" ) and mortgage loans from the Savings Bank. The Savings
Bank's 50% owned subsidiary, SFC, originates, services and sells automobile
loans to FNII, the Saving Bank and its other parent corporation.

    First Northern is based in Green Bay, Wisconsin and conducts its business
from 19 offices located in a contiguous, eight-county (Brown, Marinette,
Manitowoc, Door, Shawano, Outagamie, Waupaca, and Calumet) area in Northeastern
Wisconsin.

    On August 18, 1997, First Northern effected a 2-for-1 stock split in the
form of a 100% stock dividend. Unless otherwise indicated, all shares and per
share information have been restated to reflect the stock split.

MERGER AGREEMENT WITH MUTUAL SAVINGS BANK. On February 22, 2000, First Northern,
and Mutual Savings Bank, a Wisconsin-chartered mutual savings bank ("Mutual"),
announced 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"). 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 the Survivor Common Stock, which
may not be less than 40% or more than 70%; the balance will be paid in cash.
Each First Northern stockholder will be entitled to elect to receive (a) cash,
(b) Survivor Common Stock or (c) as to First Northern stockholders 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 the 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 a 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 stockholders in the

                                                                           FN-48

<PAGE>   232



Merger. As a result of the Restructuring, Mutual Savings Bank and the Savings
Bank, 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
stockholders of First Northern and approval by the OTS, the FDIC and the
WDFI--Administrator. 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 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 at
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.

CAUTIONARY FACTORS. This Form 10-K contains or incorporates by reference various
forward-looking statements concerning the Company's prospects that are based on
the current expectations and beliefs of management. Forward-looking statements
may also be made by the Company from time to time in other reports and documents
as well as oral presentations. When used in written documents or oral
statements, the words "anticipate," "believe," "estimate," "expect," "objective"
and similar expressions are intended to identify forward-looking statements. The
statements contained herein and such future statements involve or may involve
certain assumptions, risks and uncertainties, many of which are beyond the
Company's control, that could cause the Company's actual results and performance
to differ materially from what is expected. In addition to the assumptions and
other factors referenced specifically in connection with such statements, the
following factors could impact the business and financial prospects of the
Company: general economic conditions; legislative and regulatory initiatives;
increased competition and other effects of the deregulation and consolidation of
the financial services industry; monetary and fiscal policies of the federal
government; deposit flows; disintermediation; the cost of funds; general market
rates of interest; interest rates or investment returns on competing
investments; demand for loan products; demand for financial services; changes in
accounting policies or guidelines; unforeseen future costs and consequences of
the year 2000 problem; and changes in the quality or composition of the Savings
Banks loan and investment portfolios and the investment portfolio of FNII.
Further, First Northern's Merger Agreement with Mutual is subject to regulatory,
First Northern stockholder and Mutual depositor approvals and other closing
conditions.

THE THRIFT INDUSTRY. The operations of First Northern and the Savings Bank, as
well as other savings associations and other financial institutions, are
significantly influenced by general economic conditions, by the related
monetary, tax and fiscal policies of the federal government and by the policies
of regulatory authorities, including the Board of Governors of the Federal
Reserve System ("Federal Reserve Board"), the Office of Thrift Supervision
("OTS"), the Federal Deposit Insurance Corporation ("FDIC") and in the case of
First Northern and the Savings Bank, the Wisconsin Department of Financial
Institutions---Division of Savings Institutions ("WDFI -- Administrator"). First
Northern's results of operations are also affected by accounting principles and
regulations adopted by the Financial Accounting Standards Board ("FASB") and
other organizations. Deposit flows and costs of funds are influenced by interest
rates on competing investments, general market rates of interest, the level of
personal savings and the public perception of the financial strength of the
industry. Lending activities are affected by the demand for mortgage financing
and other types of loans, which in turn is affected by the interest rates at
which such financing may be offered and market forces acting upon the supply of
housing and the availability of funds.

RECAPITALIZATION OF SAIF. The Savings Association Insurance Fund ("SAIF") of the
FDIC was recapitalized during 1996 by a one-time special assessment imposed on
all SAIF members. The $2,856,000 assessment paid by First Northern had a
significant impact on its 1996 financial results. However, the effect of the
recapitalization is a significant reduction in federal deposit insurance
premiums for SAIF-insured institutions on an ongoing basis.

MARKET AREA AND COMPETITION. First Northern's primary market area is an eight
county area in Northeastern Wisconsin, which surrounds Green Bay, the third
largest city in Wisconsin. First Northern operates 19 offices located in 14
cities in this area. These counties and cities are serviced by four Green Bay
area television stations and are included in the circulation of a Green Bay
newspaper.



                                                                           FN-49
<PAGE>   233



    Financial organizations, such as First Northern, experience intense
competition in both attracting and retaining deposits and in making real estate
and consumer loans. First Northern's management believes that its share of the
deposit market is approximately 10% and that its mortgage lending market share
in its primary market area is approximately 9%. Most direct competition for
deposits has come from commercial banks, credit unions, stock brokerage firms
and money market mutual funds. In addition to offering competitive types of
accounts and interest rates, the principal methods used by First Northern to
attract deposits include the offering of a variety of services, and convenient
business hours and branch locations, with inter-branch deposit and withdrawal
privileges at each location. Competition in originating real estate loans comes
primarily from commercial banks and mortgage bankers. The primary factors in
competing for loans are interest rates and interest rate adjustment provisions,
loan fees and the quality of service to borrowers.

    The Wisconsin Statutes governing savings associations and their holding
companies provide for regional reciprocal interstate banking which permits
additional competitors to enter First Northern's primary market and may tend to
create further concentration in the financial services industry. Under Wisconsin
law, Wisconsin chartered savings institutions may open branches in Illinois,
Indiana, Iowa, Kentucky, Michigan, Minnesota, Missouri and Ohio, provided that
reciprocal legislation is adopted in such states (the "Regional States").
Currently, all but Missouri have adopted reciprocal legislation. A Wisconsin
based savings and loan holding company is able to acquire a savings institution
or holding company in any of the Regional States and such a holding company
located in a Regional State is able to make similar acquisitions in Wisconsin.
In addition, the Riegle-Neal Interstate Banking and Branching Efficiency Act of
1994, which allows bank holding companies that are adequately capitalized and
adequately managed to acquire banks anywhere in the nation regardless of whether
the acquisition is prohibited under state law, also created further competition
and concentration in the financial services industry.

    See "--Regulation--Federal Regulation of Holding Companies --
Gramm-Leach-Bliley Act" below for a description of this significant new federal
legislation which could have a far reaching impact on the financial services
industry.

LENDING ACTIVITIES. First Northern has traditionally concentrated on
originations of adjustable and fixed interest rate one- to four-family mortgage
loans and consumer loans. First Northern also originates five or more family
residential, commercial real estate and short-term construction mortgage loans.
Adjustable interest rate mortgage loans are originated for First Northern's
portfolio; while 30 year fixed interest rate mortgage loans are primarily
originated for sale in the secondary mortgage market. Fixed interest rate
mortgage loans with terms of 15 and 20 years are retained in First Northern's
mortgage loan portfolio. At December 31, 1999, approximately 75% of First
Northern's mortgage loan portfolio was interest rate adjustable as compared to
76% at December 31, 1998.

    To aid in matching maturities of its assets and liabilities, First Northern
originates second mortgage loans, automobile, boat, recreational vehicle and
other types of consumer loans. These loans are generally of shorter maturities
than first mortgage loans and are originated at both adjustable or fixed
interest rates.

    First Northern started a commercial banking division in 1999, which
originates commercial loans and commercial real estate loans. First Northern
hired an experienced commercial banking manager to guide the development of this
division. At December 31, 1999, the commercial banking division had originated
commercial loans of $5.0 million and commercial real estate loans of $14.4
million, which are reported in mortgage loan originations.

    First Northern lends primarily in its eight county market area in
Northeastern Wisconsin. At December 31, 1999, approximately 99.2% of the total
dollar amount of First Northern's mortgage loans outstanding were on properties
located in Wisconsin with the other 0.8% representing properties located
primarily in other Midwestern states.

    First Northern's loan portfolio of $759.2 million before deductions at
December 31, 1999 was 90.4% by dollar volume of its total assets. As of that
date, approximately 63.4% by dollar volume of the loan portfolio consisted of
conventional first mortgage loans secured by one- to four-family residences,
with an additional 25.7% by dollar volume in consumer loans, 6.6% by dollar
volume in multi-family (more than four) residential properties, 3.2% by dollar
volume in commercial real estate properties, 0.6% by dollar volume in commercial
loans and 0.5% by dollar volume in other properties.

LOAN INTEREST RATES AND TERMS. Interest rates charged on First Northern's loans
are affected primarily by the demand for such loans and the supply and cost of
money available for lending purposes. These factors are in turn affected by
general economic conditions and such other forces as monetary policies of the
federal government, including the Federal Reserve Board, the general supply of
money, tax policies and governmental budgetary matters. Certain lending
activities of Wisconsin chartered savings associations are subject to Wisconsin
usury laws.

    The maturities and average periods that loans actually remain outstanding,
together with the variability of loan interest provisions, in each case as
compared with the corresponding factors for loan funding sources, are the key
determinants of a lender's exposure to interest rate risk. Loan sales may also
be used as a means of reducing interest rate risk. First Northern's general
policy, which is subject to review by management as a result of changing market
and economic conditions, and other factors, is to retain all adjustable interest
rate mortgage loans in its portfolio and to keep up to approximately 25% of the
mortgage portfolio in fixed interest rate mortgage loans. The percentage of
fixed mortgage loans held in the loan portfolio was increased from 20% to 25% in
1998 as a result of First Northern's asset and liability position which allowed
for some additional interest rate risk and other investment opportunities in the
market. First Northern estimates that generally not more than 5% of the total
mortgage portfolio will be in 30 year fixed interest rate mortgage loans. This
policy is part of First Northern's asset/liability management strategy.

    Mortgage loans made by First Northern generally are long-term loans,
amortized on a monthly basis with principal and interest due each month. First
Northern does not include a prepayment penalty on one- to four-family
owner-occupied mortgage loans. Although the original contractual loan payment
period for mortgage loans normally ranges from 15 to 30 years, First Northern's
experience has been that, because of prepayments in connection with refinancing
and sales of property, mortgage loans typically remain outstanding for a
substantially shorter period. First Northern estimates that the average range of
time mortgage loans are outstanding is approximately six to ten years.

    Management of First Northern is committed to managing the maturities of
assets and liabilities. To aid in this , management's policy is to emphasize the
origination of consumer and commercial loans and other loans having short
maturities, such as three to six years, and mortgage loans which are interest
rate adjustable or are eligible for sale in the secondary market. At December
31, 1999, consumer loans (second mortgage, automobile and other consumer loans)
outstanding totaled $194.7 million. Consumer loan originations and purchases for
the year ended December 31, 1999 were $132.7 million, of which $29.4 million or
22.2% were interest rate adjustable. Consumer loan originations and purchases in
1998 were $99.6 million, of which $32.8 million or 32.9% were interest rate
adjustable, and in 1997 originations and purchases were $98.2 million, of which
$29.2 million or 29.7% were interest rate adjustable.

    Since February 1985, First Northern has originated mortgage loans using
contracts which contain interest rate adjustment clauses allowing a lifetime
interest rate adjustment of between 5% to 8% over the original contract interest
rate on all residential mortgage loans and subject to annual interest rate
adjustment caps of up to 2%. First Northern's ability to successfully market
such loans depends on, among other things, prevailing interest rates, the
volatility of interest rates and the public's acceptance of adjustable interest
rate mortgage loans. First Northern has generally fixed the interest rate for
the first one, two, three or five years of the loan term. First Northern also
maintains a policy of including a "due on sale" clause in its mortgage loans.
This clause generally gives First Northern the right, subject to certain
restrictions, to declare a loan immediately due and payable in the event, among
other things, that the borrower sells or otherwise disposes of the real property
subject to the mortgage without first either obtaining First Northern's consent
or repaying the loan.

LOAN ORIGINATIONS. First Northern has general authority to lend anywhere in the
United States; however, it has chosen to concentrate its mortgage origination
activities in Northeastern Wisconsin with primary emphasis in the counties
served by its offices. As of December 31, 1999, First Northern had only 93 loans
secured by out-of-state properties, representing $4.3 million or 0.8% of the
total dollars in its mortgage loan portfolio. First Northern's mortgage lending
is subject to written, non-discriminatory underwriting guidelines and to loan
origination procedures approved annually by First Northern's Board of Directors.
Property appraisals by independent appraisers, in accordance with First
Northern's appraisal policy, are required. Detailed loan applications are
obtained to determine the borrower's ability to repay, and the more significant
items on these applications are verified through the use of credit reports,
financial statements and employment and income confirmations. Loans are reviewed
and approved as directed by the underwriting guidelines established by the Board
of Directors.

    At December 31, 1999, First Northern serviced for others $151.4 million of
whole loans and participation interests in mortgage loans. In addition, as of
December 31, 1999, First Northern had approximately $140.2 million of 15, 20 and
30 year fixed interest rate mortgages in its mortgage loan portfolio. See "Loan
Interest Rates and Terms" above. In 1999, 1998 and 1997, First Northern sold
$20.1, $63.2, and $18.7 million, respectively of fixed interest rate mortgage
loans to the secondary market in accordance with First Northern's asset and
liability management policy. First Northern also originates mortgage loans for
the Wisconsin Department of Veterans Affairs ("WDVA") and the Wisconsin Housing
and Economic Development Authority ("WHEDA"), which result in additional
origination fees and servicing income. First Northern does not currently
originate a significant amount of Federal Housing Administration ("FHA") insured
or Veterans Administration ("VA") partially guaranteed loans.

    In addition to traditional mortgage lending activities, First Northern has
participated in various state and local special loan


                                                                           FN-51

programs. Many of these programs are designed specifically to make home
ownership more available to qualified low/moderate income families. Through the
Federal Home Loan Bank ("FHLB") of Chicago's Affordable Housing Program, First
Northern has obtained funding for down payment and closing cost assistance to
assist low income first-time home buyers.

    During 1999, First Northern purchased $31.9 million of single-family home
loans, $1.5 million in multi-family loans and $3.5 million in commercial real
estate loans from others. In 1998, First Northern purchased $15.0 million of
single-family home loans, $1.7 million in multi-family loans, and $0.6 million
in commercial real estate loans. In 1997, First Northern purchased $7.8 million
of single-family loans, $3.7 million of multi-family loans, and $1.0 million of
commercial real estate loans.

    First Northern requires borrowers to obtain title insurance or abstracts of
title, depending on the type of mortgage product, on first mortgage real estate
loans. Home equity loan borrowers are required to obtain a title search before
and after the loan is originated to assure First Northern that the loan has been
properly recorded and secured. Borrowers also must obtain hazard insurance prior
to closing and, when required by the Department of Housing and Urban
Development, flood insurance. Borrowers may be required to advance funds on a
monthly basis together with each payment of principal and interest to a mortgage
escrow account from which First Northern makes disbursements for items such as
real estate taxes and private mortgage insurance premiums as they become due.
First Northern is required by Wisconsin law to pay interest on mortgage escrow
accounts for loans originated after January 31, 1983 that are secured by one- to
four-family, owner-occupied residences. The interest rate is based on the annual
average of passbook interest rates paid by all Wisconsin financial institutions
(2.74% for 1999). Currently, approximately 84.2% of the escrow dollars are
interest bearing. The interest rate paid on escrow dollars is adjusted annually.
The interest rate to be paid on qualified mortgage escrow dollars in 2000 is
2.51%.

    Regulations of the WDFI-Administrator also limit the amount, which First
Northern may lend up to specific percentages of the value of the real property
securing the loan (referred to as "loan-to-value" ratios), as determined by an
appraisal at the time the loan is originated. A loan secured by a first lien
mortgage may not exceed 90% of the appraised value of the real estate security
unless, among other things, the portion exceeding that percentage is insured or
guaranteed by a mortgage insurance company against losses resulting from
borrower default or the loan is guaranteed by a federal or state agency. First
Northern's policy is to not make first mortgage loans in excess of 80% of the
lower of the appraised value or the purchase price unless the excess is insured
by private mortgage insurance or the loan is guaranteed by a federal or state
agency. Real estate loans secured by other than a first lien must also conform
generally to First Northern's policy of limiting loans to 80% of value; however,
First Northern adjusted its policy in 1998 to allow loan amounts to equal 100%
of value. All mortgage loan applications are reviewed by First Northern's
corporate underwriting staff to ensure compliance with its uniform loan
underwriting guidelines.

    The federal agencies regulating First Northern have also established real
estate lending standards, which, among other things, create loan-to-value ratios
for various real estate loan categories. First Northern's current underwriting
standards, as stated above, conform with these real estate lending standards.

    First Northern has been expanding its consumer lending portfolio, which
generally consists of home equity, automobile, boat, recreational vehicles,
credit card and other loans, to obtain higher yields, to serve the needs of its
customers and to aid in the management of interest rate risk. In addition, First
Northern purchases automobile loans from its subsidiary, SFC, which originates
automobile loans on an indirect basis for its parent companies. First Northern
has historically experienced relatively low delinquencies and few losses on
consumer loans.

    First Northern added commercial loans to its product line offering the
second quarter of 1999. An experienced commercial loan manager with over 20
years of commercial lending experience was hired to develop the commercial
banking area. In addition to the commercial and industrial loans originated,
First Northern has experienced an increase in commercial real estate lending,
which is reported in the mortgage loan originations as a result of the
commercial loan product line. First Northern anticipates it will continue to
emphasize commercial loan growth.

                                                                           FN-52

(1) First Northern's mortgage construction loans are originated for either the
    construction phase or the combined construction and full amortization term
    of the loan.

          Of the $717.7 million of loans contractually due after December 31,
2000, approximately $256.2 million have fixed interest rates and approximately
$461.5 million have adjustable interest rates.

          Contractual maturities of loans do not reflect the actual life of the
loan portfolio. The average life of mortgage loans is substantially less than
their contractual terms because of loan prepayments. The average life of
mortgage loans tends to increase, however, when current mortgage market interest
rates exceed interest rates on existing mortgages and decrease when mortgage
interest rates decline. The average life of consumer loans is affected by the
general and local economy.

                                                                           FN-53

(1) Refinanced mortgage loans are stated as gross dollars. Net new refinanced
    dollars for the years ended December 31, 1999, 1998, 1997, 1996 and 1995,
    were $46.3 million, $95.0 million, $25.7 million, $24.9 million, and $10.8
    million, respectively. Net new dollars are the additional dollars that were
    disbursed above an existing loan balance for the same borrower and property.

        First Northern is permitted to make secured and unsecured consumer loans
including automobile, recreational vehicle, marine and other consumer loans,
home equity, property improvement, manufactured housing, education and deposit
account loans. At December 31, 1999, consumer loans represented 25.7% of total
loans.

LOAN FEE INCOME. A borrower on a one- to four-family owner-occupied residence
may be charged a loan origination fee or a processing fee of up to 1% of the
loan amount, with the actual amount being dependent upon, among other things,
market conditions at the time of origination. These fees are in addition to
appraisal and other third party fees paid by the borrower to First Northern at
the time of application. Loan origination and commitment fees and certain direct
loan origination costs are being deferred and the net amounts amortized as an
adjustment to the related loan's yield. First Northern is amortizing these
amounts using the level-yield method, adjusted for prepayments, over the
contractual life of the related loans. Currently, there are no loan fees charged
on consumer loans.

USURY LIMITATION AND INTEREST RATE ADJUSTMENT PROVISIONS. Any loan secured by a
real estate mortgage and made, refinanced, renewed, extended or modified after
November 1, 1981, is not subject to a maximum interest rate. Consumer loans of
$25,000 or less are generally subject to the Wisconsin Consumer Act which
establishes disclosure requirements for interest rates and finance charges and,
for transactions entered into before November 1, 1984, limits the maximum
finance charges.


                                                                           FN-54

    Mortgage lenders have historically had authority under Wisconsin law to
include interest adjustment clauses in loan contracts. Before June 12, 1976, the
only limit on interest adjustment increases was the general usury ceiling.
However, as of that date, Wisconsin law began to distinguish between two kinds
of interest adjustment clauses in connection with loans on owner-occupied one-
to four- family residential property: (1) those that tie interest adjustments to
fluctuations in an approved index ("indexed" interest adjustment provisions);
and (2) those that do not ("unindexed" interest adjustment provisions). Subject
to certain statutory restrictions, interest adjustments under an unindexed
interest adjustment provision are solely at the option of the lender.

    Under Wisconsin law, unindexed adjustable rate provisions contained in first
lien mortgage loans made on one- to four-family owner-occupied dwellings may:
(1) permit rate increases to be made as often as once every 6 months, upon 30
days' written notice, and in increments of up to 1% each; and (2) enable a
lender that has waived a permitted interest rate increase to subsequently
increase the interest rate to the level that would have been in effect had the
opportunity for an increase not been waived.

    Mortgages that are subject to indexed interest rate adjustment provisions
are treated in substantially the same way under Wisconsin law. However, instead
of increases or decreases occurring solely at the discretion of the lender,
interest rates may be increased, and must be decreased, in accordance with
changes in the approved index. Unlike its unindexed adjustable rate counterpart,
adjustments made under an indexed adjustable rate provision governed by the 1981
law may be made at intervals more frequent than 6 months.

    Borrowers may prepay their loan without penalty during the 30 days following
notice of a rate increase, or at any time after 5 years from the date of the
loan.

    First Northern has originated both unindexed and indexed adjustable interest
rate mortgages. With both types of adjustable rate forms, First Northern has
generally fixed the interest rate for the first one, two, three or five years of
the loan term. The unindexed adjustable interest rate loans also provide for a
maximum interest rate adjustment of 1% during each 12 month period thereafter.
The indexed adjustable rate loan provides for a maximum interest rate adjustment
of the lesser of the index or 1% to 2% depending on origination date of the
loan, during each 12 month period. Since February 1985, First Northern has
originated adjustable interest rate mortgage loans using contracts which contain
interest rate adjustment clauses allowing a lifetime interest rate adjustment of
between 5% and 8% over the original contract interest rate on all residential
mortgage loans.

    First Northern has been able to exercise its escalation and de-escalation
rights under the interest rate adjustments clauses on its mortgage loan
portfolio. The use of the adjustment clause gives First Northern greater control
over its income and portfolio retention due to its ability to increase or
decrease interest yields on its mortgage portfolio. See "Loan Interest Rates and
Terms" above.

CLASSIFIED ASSETS AND DELINQUENCIES. When a borrower fails to make a required
payment on a loan, First Northern or SFC attempts to have the deficiency cured
by contacting the borrower. Contacts are made after a payment is more than 30
days past due and, in most cases, deficiencies are cured promptly. If the
delinquency exceeds 90 days and is not cured through First Northern's normal
collection procedures, First Northern will institute measures to remedy the
default, including commencing a foreclosure action or accepting a voluntary deed
of the secured property in lieu of foreclosure from the mortgagor or
repossessing other collateral. If a foreclosure action is instituted and the
loan is not reinstated, paid in full, or refinanced, the property is sold at a
judicial sale at which, in most instances, First Northern is the buyer.

    Under Wisconsin law, a mortgagor is afforded a period of time, subsequent to
the entry of judgment and prior to judicial sale, within which to redeem the
equity in the property ("equity right of redemption"). The length of the equity
right of redemption varies depending on the form of foreclosure proceedings
selected by the lender, the type and condition of the real estate security and
other factors. The majority of First Northern's residential foreclosures follow
a form which provides a 6 month equity right of redemption and a waiver of any
deficiency judgment against the borrower. Use of this process takes
approximately 8-12 months from commencement of the action to judicial
confirmation of the sale.

    The OTS has established a classification system for problem assets. Under
the OTS regulation, problem assets are classified as "substandard," "doubtful,"
or "loss." Assets classified as loss are required to be charged-off. Assets
classified as doubtful or substandard do not require a write-off of the amounts
so classified but may necessitate additions to the general allowance for loan
losses. An institution's determination as to the classification of its assets
and the amount of valuation allowances are subject to review by the District
Director of the OTS or the FDIC, who could order the establishment of additional
loan loss allowances.

                                                                           FN-55

</TABLE>


    The increase in the amount of total classified assets in 1999 was the result
of an increase in overall delinquencies and the fact that December 31, 1998,
total classified assets were very low.

ALLOWANCES FOR LOSSES. Allowances for losses on loans, real estate, and
repossessed assets are based on management's evaluation of various factors
including, but not limited to, general economic conditions, loan portfolio
composition, prior loss experience, estimated sales price of collateral,
regulatory environment and holding and selling costs.

    While First Northern has a low level of non-performing assets and low
historical charge-off experience, the inherent credit risk within the portfolio
(primarily relating to the indirect automobile loan portfolio and commercial
loans) has increased. It is this increased credit risk which primarily resulted
in the increase in the loan loss allowance.


    Management believes that the allowances for losses on loans, real estate,
and repossessed assets are adequate. While management uses available information
to recognize losses on loans and real estate owned, future additions to the
allowances may be necessary based on changes in economic conditions or
regulatory requirements.








                                                                           FN-56

    Interest income on loans is accrued and credited to operations based on the
principal amount outstanding. The accrual of interest income is generally
discontinued when a loan becomes 90 days past due as to principal or interest
and/or when, in the opinion of management, full collection is unlikely. When
interest accruals are discontinued, uncollected interest credited to income in
the current year is reversed and uncollected interest accrued in the prior year
is charged to the allowance for loan losses. Management may elect to continue
the accrual of interest when the loan is in the process of collection and the
value of collateral is sufficient to cover the principal balance and accrued
interest. Interest received on non-accrual loans generally is either applied
against principal or reported as interest income, according to management's
judgment as to the collectibility of principal. Generally, 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 no
longer in doubt.

     (1)     The expected maturities for mortgage-related securities will differ
             from contractual maturities because borrowers may have the right to

             penalties.

     DEPOSIT ACTIVITIES. First Northern has a number of different programs
     designed to attract both short-term and long-term deposits from the general
     public. These programs include regular passbook accounts, NOW checking
     accounts, money market deposit accounts, fixed rate and variable rate
     certificate accounts and negotiated rate certificates, as well as certain
     other accounts. Included among those programs are individual retirement
     accounts ("IRAs") and self-employed pension plan ("SEPP") accounts.

             The specific programs offered by First Northern have changed over
     time as new types of accounts and minimum denomination requirements have
     been authorized. Currently there are no statutory or regulatory required
     minimum denominations or interest rate ceilings on any deposit accounts.
     First Northern currently offers deposit accounts with minimum balance
     requirements and interest rates as follows:

(1) Some of the NOW Checking Accounts offered by First Northern do not bear
    interest.
(2) As a practical matter, although subject to First Northern's right to impose
    a prior notice requirement, deposits may be invested in and withdrawn from
    passbook accounts without restriction. Interest is computed daily from the
    date of deposit to the date of withdrawal and credited quarterly at a rate
    established by the Investment Committee of management within regulatory
    limits.

BORROWED FUNDS. First Northern has a line of credit with the FHLB of Chicago and
has borrowed from the FHLB on an overnight and fixed interest rate basis to
assist with funding loan originations.

         From time to time, First Northern borrows funds under repurchase
agreements. First Northern accepts funds from municipalities and school
districts. When the amounts of such funds are in excess of FDIC insurance
limits, First Northern collateralizes its obligation to repay such parties
through repurchase agreements. Repurchase agreements are used to lock-in a
profit spread to First Northern. Furthermore, because the repurchase agreements
from municipalities and school districts are not considered deposits, First
Northern does not pay premiums to the FDIC on such amounts. At December 31, 1999
and 1998, First Northern had no borrowings under repurchase agreements as
compared to $0.9 million of borrowings under repurchase agreements at December
31, 1997. The weighted average interest rate of the repurchase agreements as of
December 31, 1997 was 5.79%. See Note 7 of the Notes to Consolidated Financial
Statements.


                                                                           FN-66

          Borrowings increased to $185.9 million at December 31, 1999, as
compared to $92.0 million at December 31, 1998, primarily as a result of the
loan portfolio growth, decreased loan sales and modest deposit growth. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."

YIELDS EARNED AND RATES PAID. First Northern's net earnings depend primarily
upon the spread between the income it receives from its loan and investment
portfolios and its cost of money, consisting of interest paid on deposit
accounts and borrowings.

         The following table sets forth First Northern's weighted average yields
earned on mortgage loans, consumer loans, and investment and mortgage-related
securities; the weighted average interest rates paid on deposits and borrowings;
and the spread between yields earned and rates paid at the dates indicated.
Since the majority of First Northern's deposit accounts are market rate
accounts, the cost of deposits will likely continue to be subject to interest
rate fluctuations.

(1)  At December 31, 1999, 1998, 1997 and 1996, overnight borrowing interest
     rates were unusually high or low and, for the purpose of this report, First
     Northern used an average of the overnight borrowing interest rates from the
     preceding week to more accurately reflect the cost at December 31 of the
     respective years.

Analysis of Financial Condition and Results of Operations."

AVERAGE EQUITY TO AVERAGE ASSETS. The ratio of average equity to average assets
measures a financial institution's financial strength. At December 31, 1999,
savings and loan associations in Wisconsin were required to maintain an average
equity to average assets ratio of at least 6.00%. At December 31, 1999, 1998,
1997, 1996 and 1995 the Savings Bank's average equity to average assets ratio
was 9.99%, 10.83%, 11.24%, 12.14%, and 12.99%, respectively.

</TABLE>

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

(1)    The Cash Dividends Payout Ratio was significantly increased in 1996 as a
       result of the SAIF special assessment, which significantly reduced net
       income per share. Without the SAIF special assessment, the Cash Dividend
       Payout Ratio would have been 55.0%.


SUBSIDIARIES. GNFSC, a wholly owned subsidiary of the Savings Bank, engages in
the sale of credit life and disability insurance, and offers brokerage services
to the public, including the sale of tax deferred annuities and mutual funds.
First Northern's investment in GNFSC as of December 31, 1999 was $391,000.

         FNII, a wholly owned Savings Bank subsidiary, was established September
2, 1994 for the purpose of managing a majority of First Northern's investment
portfolio. In April 1998, FNII began to purchase loans originated by SFC and the
Savings Bank moved its indirect auto loan portfolio to FNII. In March 1999, the
Savings Bank sold a $56.1 million mortgage loan participation to FNII. FNII
managed approximately $32.4 million of investments, $51.3 million of mortgage
loans and $75.3 million of indirect auto loans at December 31, 1999. First
Northern's investment in FNII as of December 31, 1999 was $161,858,000.

         In March 1992, the Savings Bank acquired a 50% stock interest in SFC
from another financial institution. SFC originates, sells, and services indirect
automobile loans. As a result of this acquisition, SFC will on a regular basis,
sell such loans to First Northern or FNII but retain the servicing of the loans.
In April 1998, SFC began selling such loans to FNII but retains the servicing of
the loans. First Northern's investment in SFC as of December 31, 1999 was
$40,000.

         Keystone Financial Services, Inc. ("Keystone"), a wholly owned
subsidiary of the Savings Bank, also engaged in the sale of credit life and
disability insurance and tax deferred annuities and offered discount brokerage
services for Prime Federal prior to the merger with and into First Northern.
After the merger, First Northern transferred such business to GNFSC. Keystone is
inactive, but will continue to be a wholly owned subsidiary of the Savings Bank
for possible future use in a related or other area. First Northern's investment
in Keystone as of December 31, 1999 was $100.

         Another wholly owned subsidiary of the Savings Bank, First Northern
Financial Services, Inc., operated as a consumer lending subsidiary through
1981. As a result of legislative changes, First Northern now directly engages in
consumer lending activities. First Northern Financial Services, Inc. is
inactive, but it continues in existence for possible future use in a related or
other area. First Northern's book value investment in First Northern Financial
Services, Inc. as of December 31, 1999 was $100.

         The Financial Institutions Reform, Recovery and Enforcement Act of 1989
("FIRREA") imposes restrictions on savings associations' powers. It essentially
creates parallel regulation for state and federally chartered savings
associations and prevents state associations, such as the Savings Bank, from
exercising powers not authorized to federal associations or which the FDIC deems
to constitute a serious risk to the safety, soundness or stability of an insured
institution and/or the SAIF or to be inconsistent with sound banking principles.
The FDIC has informed First Northern that the certain activities that GNFSC is
performing are permissible for a federally chartered savings association but not
a national bank. Therefore, First Northern is required to deduct its investment
and loans to GNFSC when calculating its core, tangible and risked-based capital
ratios.

6.   The weighted average number of shares outstanding, including common stock
     equivalents, for the three months ended March 31, 2000 and 1999 were
     8,714,677 and 8,986,029, respectively.

7.   Certain amounts in the 1999 financial statements have been reclassified to
     conform to the 2000 presentations.

8.   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 share 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.

forward-looking statements. The statements contained herein and such future
statements involve or may involve certain assumptions, risks and uncertainties,
many of which are beyond the Company's control, that could cause the Company's
actual results and performance to differ materially from what is expected. In
addition to the assumptions and other factors referenced specifically in
connection with such statements, the following factors could impact the business
and financial prospects of the Company: general economic conditions; legislative
and regulatory initiatives; monetary and fiscal policies of the federal
government; deposit flows; disintermediation; the cost of funds; general market
rates of interest; interest rates or investment returns on competing
investments; demand for loan products; demand for financial services; changes in
accounting policies or guidelines; changes in the quality or composition of the
Savings Bank's and FNII's loan and investment portfolios; the status of our
proposed merger with Mutual Savings Bank; and other factors referred to in the
reports filed with the Securities and Exchange Commission.


                               RECENT DEVELOPMENTS

MERGER AGREEMENT WITH MUTUAL SAVINGS BANK. On February 22, 2000, First Northern,
and Mutual Savings Bank, a Wisconsin-chartered mutual savings bank ("Mutual"),
announced 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"). 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 the Survivor Common Stock, which may not be less
than 40% or more than 70%; the balance will be paid in cash. Each First Northern
stockholder will be entitled to elect to receive (a) cash, (b) Survivor Common
Stock or (c) as to First Northern stockholders 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


                                     FN-80

<PAGE>   264

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 the 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 a 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 stockholders in the Merger. As a result of the Restructuring, Mutual
Savings Bank and the Savings Bank 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
stockholders of First Northern and approval by the OTS, the FDIC and the
WDFI--Administrator. 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 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 at
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.


                               FINANCIAL CONDITION

BALANCE SHEET

CASH AND CASH EQUIVALENTS. Cash and cash equivalents decreased $7.7 million at
March 31, 2000, as compared to December 31, 1999, primarily because the Savings
Bank maintained additional cash at December 31, 1999, as a precaution against
possible events associated with Year 2000 concerns. Shortly after December 31,
1999, the cash was redeployed by paying down short-term borrowings.

SECURITIES AVAILABLE-FOR-SALE. Investment securities available-for-sale
increased $0.6 million as of March 31, 2000, as compared to December 31, 1999,
primarily as a result of the reinvestment


                                     FN-81

<PAGE>   265

of maturing securities and the interest earnings on securities being reinvested,
partially offset by decreased market value. (See Notes to Unaudited Consolidated
Financial Statements--3. Securities Available-for-Sale)

Mortgage-related securities available-for-sale decreased $0.2 million at March
31, 2000, as compared to December 31, 1999, as a result of prepayments and
repayments of the underlying security.

SECURITIES HELD-TO-MATURITY. Investment securities held-to-maturity were almost
unchanged from March 31, 2000 as compared to December 31, 1999.

Mortgage-related securities held-to-maturity increased $0.3 million as a result
of the purchase of additional mortgage-related securities.

LOANS HELD FOR SALE. At March 31, 2000, First Northern had $2.3 million of fixed
interest rate mortgage and education loans classified as held for sale as
compared to $1.1 million at December 31, 1999. The increase in loans held for
sale is primarily the result of education loans originated during the first
quarter of 2000, all of which are contractually assigned to be sold.

<PAGE>   266


LOANS RECEIVABLE. Loans receivable increased $29.7 million at March 31, 2000, as
compared to December 31, 1999, as a result of: (i) mortgage loan originations
and purchases; (ii) reduced prepayments or refinancing of mortgage loans; (iii)
increased automobile and second mortgage loan originations; and (iv) the
initiation of a commercial lending program in the second quarter of 1999. Loan
originations and purchases are as follows:

Mortgage loan originations and purchases decreased $7.7 million for the first
quarter of 2000, as compared to the same period in 1999, primarily as the result
of decreased refinancing of existing First Northern mortgage loans. Construction
and purchase mortgage loan originations increased in the first quarter of 2000
primarily as a result of increased construction and purchase activity within
First Northern's market. Although total mortgage loan originations decreased for
the first quarter of 2000, the mortgage loan portfolio outstanding increased
$16.8 million (before deductions for undisbursed loan proceeds, allowance for
loan losses and unearned loan fees) for the first quarter of 2000. The increased
mortgage loan portfolio was primarily the result of: (i) increased adjustable
interest rate mortgage loan originations; (ii) reduced prepayments of principal
on outstanding loans; and (iii) reduced refinancing of existing mortgage loans,
all of which, we believe, is attributable to the increase in interest rates on
fixed interest rate mortgage loans.

First Northern added commercial banking services to its existing product lines
in the second quarter of 1999. To manage the commercial banking department,
First Northern hired a commercial loan manager with 20 years of commercial
banking experience. At March 31, 2000, First Northern's commercial loan
portfolio outstanding was at $9.7 million and management anticipates that this
segment of its loan portfolio will continue to increase. Management believes
commercial banking will enable First Northern to enhance its interest earning
assets and its interest rate spread management.

Consumer loan originations and purchases increased $6.2 million in the first
quarter of 2000 as compared to the same period in 1999, primarily as the result
of the increase in second mortgage loan originations and indirect automobile
originations from SFC. Second mortgage originations have increased as a result
of: (i) management's emphasis; (ii) increased marketing; and (iii) the use of an
introductory interest rate for a line-of-credit product secured by a second
mortgage. SFC increased its automobile originations by continued personalized
service and competitive interest rates.

Loans sold in the first quarter of 2000, as compared to the first quarter of
1999, decreased as a result of the reduction in 30 year fixed interest rate
mortgage loan originations. First Northern retains all adjustable interest rate
mortgage loan originations in its portfolio; retains the majority of 15 and 20
year fixed interest rate mortgage loans; and sells most 30 year fixed interest
rate mortgage loans in the secondary market. First Northern is contractually
committed to sell its current education loan portfolio as well as, future
originations.

OFFICE PROPERTIES AND EQUIPMENT. First Northern entered into an operating lease
for approximately 14,000 square feet of office space in the third quarter of
1999. This office space centralized the loan servicing, origination processing,
information systems, marketing and customer support services departments of the
Savings Bank. The additional leased space is needed to accommodate growth in
these areas. Total annual cost of this office space and its associated equipment
is approximately $152,000 (after-tax).

FEDERAL HOME LOAN BANK STOCK. Stock in the Federal Home Loan Bank ("FHLB")
increased $1.5 million to $10.8 million at March 31, 2000, as compared to $9.3
million at December 31, 1999. This increase in FHLB stock is the result of
increased borrowings outstanding from the FHLB of Chicago. The FHLB requires
member institutions to purchase one share of FHLB stock for every $20,000 of
FHLB borrowings. The FHLB borrowings are secured by First Northern's 1-4 family
residential mortgage loans.

LIFE INSURANCE POLICIES. Life insurance policies or bank owned life insurance
("BOLI") increased $0.3 million in the first three months of 2000 as a result of
the increased value of the policies. BOLI is long-term life insurance on the
lives of certain current and past Savings Bank employees where the insurance
policy benefits and ownership are retained by the Savings Bank. The cash value
accumulation on BOLI is permanently tax deferred if the policy is held to the
participant's death. Management believes this an effective method to help offset
a portion of future employee benefit costs.

DEPOSITS. Deposits increased $0.8 million for the first three months of 2000 as
a result of offering competitive interest rates and the acquisition of "jumbo"
(certificates of deposit in excess of $100,000) deposits. Jumbo deposits consist
of wholesale, negotiated retail and municipal deposits which at times, are a
cheaper source of funds than retail deposits or borrowing. First Northern's
total jumbo deposits were $55.5 million at March 31, 2000.

BORROWINGS. FHLB borrowings increased $25.6 million in the first three months of
2000, primarily to fund purchases of investment securities and the growth of the
loan portfolio. First Northern will borrow monies if borrowing is a less costly
form of funding for loans and investments than the cost of acquiring deposits.
First Northern anticipates that it will continue to utilize borrowings in 2000
if borrowings incrementally add to the overall profitability of the Company.

ADVANCE PAYMENTS BY BORROWERS FOR TAXES AND INSURANCE. Advance payments by
borrowers for taxes and insurance ("escrow") decreased $0.4 million at March 31,
2000, as compared to December 31, 1999. The decrease in escrow dollars was the
result of year-end disbursement of real estate taxes from escrow accounts.

STOCKHOLDERS' EQUITY. First Northern paid a cash dividend of $0.11 per share on
February 9, 2000, to stockholders of record on January 31, 2000. The increase of
$0.01 per share represents an 10.0% increase over the fourth quarter of 1999
cash dividend of $0.10 per share.

On March 20, 2000, First Northern approved a fourth stock repurchase program to
repurchase up to 429,315 shares (5% of total shares then outstanding) in the
open market. At March 31, 2000, 18,500 shares had been purchased or committed to
be purchased at an average price of $12.4375 per share.

</TABLE>


Total non-performing loans decreased as of March 31, 2000, as compared to
December 31, 1999, primarily as a result of a decrease in non-performing
mortgage loans. Management believes non-performing loans and assets, expressed
as a percentage of total loans and assets, are far below state and national
averages for financial institutions. There are no material accruing loans which,
at March 31, 2000, management has reason to believe will become non-performing
or result in potential losses.

In addition, management believes that First Northern's allowance for loan losses
are adequate. While management uses available information to recognize losses on
loans and real estate owned, future additions to the allowances may be necessary
based on changes in economic conditions. Furthermore, various regulatory
agencies, as an integral part of their examination process, periodically review
First Northern's allowances for losses on loans and real estate owned. Such
agencies may require First Northern to recognize additions to the allowances
based on the agencies' judgement of information available to them at the time of
their examination.

All of First Northern's loans are domestic, meaning the loans are secured by
real estate or other collateral located in the continental United States.

RESULTS OF OPERATIONS

AVERAGE BALANCE SHEET AND YIELD/RATE ANALYSIS

The following table presents, for the periods indicated, the total dollar amount
of interest income from average interest-earning assets, the resultant yields,
and the interest expense on average interest-bearing liabilities, expressed both
in dollars and rates. No tax equivalent adjustments were made since First
Northern's investment portfolio does not contain tax-exempt securities. Average
balances are derived from average daily balances. The yields and rates are
established by dividing income or expense dollars by the average balance of the
asset or liability. The yields and rates for the three months ended March 31,
2000 and 1999, have been annualized.

RATE VOLUME ANALYSIS OF NET INTEREST INCOME

The interaction of changes in volume and rates earned or paid with regard to
interest-earning assets and interest-bearing liabilities has a significant
impact on net income between periods. The volume of interest-earning dollars in
loans and investments compared to the volume of interest-bearing dollars in
deposits and borrowings combined with the interest rate spread produces the
changes in net interest income between periods.

The following table sets forth the relative contribution of changes in volume
and effective interest rates on changes in net interest income for the periods
indicated.

</TABLE>


STATEMENTS OF INCOME

GENERAL. Net income decreased 7.5% for the first quarter of 2000 as compared to
the first quarter of 1999. This decrease was primarily the result of a reduction
of the net interest margin and increased operating expenses.

INTEREST AND DIVIDEND INCOME. Interest income on loans increased $1,911,000 in
the first quarter of 2000 as a result of the increased dollar amount of
mortgage, consumer and commercial loans outstanding. The average mortgage loans
outstanding increased $64.7 million or 13.4% in the first quarter of 2000 as
compared to the same period in 1999 and average consumer loans outstanding
increased $40.1 million. Commercial loans, which were introduced to First
Northern customers in the second quarter of 1999, had a balance outstanding at
March 31, 2000 of $9.7 million. The yield on the mortgage loan portfolio
decreased in the first quarter of 2000 as compared to the first quarter of 1999
as a result of interest rates on mortgage loan originations during the first
nine months of 1999 being less than the yield on the existing portfolio. Since
September of 1999, the interest rates on mortgage loan originations have
exceeded the yield on the existing mortgage portfolio. See Financial Condition -
Balance Sheet - Loans Receivable. Consumer loan yields also decreased during the
first quarter of 2000 as compared to the same


                                     FN-91

<PAGE>   275



period in 1999 as a result of interest rates on originations and purchases being
below the portfolio average yield.

Interest income on investment securities increased $133,000 for the three months
ended March 31, 2000, as a result of an increase in the dollar amount of
investment securities outstanding and an increase in the yield earned on
investment securities.

Interest income on interest-earning deposits increased slightly primarily as a
result of additional interest-earning deposits outstanding.

Interest income on mortgage-related securities increased $69,000 as a result of
the increased average mortgage-related securities outstanding and the increase
in the average interest rate earned.

INTEREST EXPENSE. Interest expense on deposits increased $429,000 primarily as
the result of increased cost of deposits and increased deposits outstanding. The
average cost of deposits increased as a result of rising general market
interests and competition's deposit interest rates offered. Since June 1999, the
Federal Open Market Committee ("FOMC") has increased interest rates five times
for a total of 1.25%. The rise in FOMC interest rates raises the interest rate
expectations of consumers and hence the need to increase interest rates on new
or renewing deposits.

First Northern has utilized various time deposit terms and "special" interest
rates on various time deposit terms to attract new deposits. In addition, the
Savings Bank has acquired jumbo deposits to aid in its deposit growth.
See Financial Condition - Balance Sheet - Deposits.

Interest expense on borrowings increased $1,583,000 in the first quarter of 2000
as compared to the first quarter of 1999 as a result of increased dollars
outstanding and increased average interest paid on those borrowings. First
Northern's growth in interest earning assets outpaced the growth in deposits
thereby necessitating an increase in borrowings. First Northern anticipates it
will continue to emphasize growth in interest earning assets and will fund a
portion of that growth with borrowings. First Northern primarily borrows from
the Federal Home Loan Bank of Chicago and staggers the borrowing maturities from
overnight to 9 years in term.

PROVISION FOR LOAN LOSSES. First Northern increased its general loan loss
allowance in the first quarter of 2000 as a result of the growth in the loan
portfolio and the type of loans originated. The loan loss allowance as of March
31, 2000, was $4,062,000 or .53% of total loans and 610.8% of non-performing
assets.

Management believes that the current loan loss allowance is adequate; however,
the adequacy of the loan loss allowance is reviewed as historical loan loss
changes, changes in the size and composition of the loan portfolio, changes in
the general economy and as may otherwise be deemed necessary.

NON-INTEREST INCOME. Fees on serviced loans increased $19,000 in the first
quarter of 2000 as a result of decreased repayments or prepayments on loans sold
(with servicing retained). As the principal of a mortgage loan which was sold,
repays or prepays, the mortgage servicing asset is reduced and netted from fees
on serviced loans, thereby reducing the income on the serviced loans. When the
repayments or prepayments decrease, such as in the first quarter of 2000, the


                                     FN-92

<PAGE>   276



amortization from the mortgage servicing assets also decreases and hence, the
income on serviced loans increases. First Northern's mortgage loan servicing
asset at March 31, 2000 was $562,700.

Loan fees and service charges increased slightly primarily as the result of late
charges collected on loans and fees collected from the Savings Bank's
line-of-credit home equity loans.

Income from deposit account service charges increased $74,000 as a result of
debit card fee income and fees from customers who overdraw their checking
account. Each time First Northern's debit card is used, a fee which varies with
each merchant, is paid to the Savings Bank by the debit card company. The
Savings Bank promotes the use of its debit card by direct mail.

Insurance commissions increased $51,000 as a result of First Northern receiving
an insurance bonus. If First Northern obtains a predetermined threshold of
insurance sales and insurance losses are below another threshold, insurance
bonuses are earned. First Northern received $49,000 in insurance bonuses in the
first quarter of 2000.

Gains on the sale of loans decreased $157,000 as a result of decreased loan
sales. First Northern sold $469,000 of loans in the first quarter of 2000 as
compared to $9,640,000 in the first quarter of 1999. Loan sales decreased
substantially in the first quarter of 2000 as a result of decreased thirty year
fixed interest rate mortgage loan originations, which are sold to the secondary
market.

Other income increased $96,000 for the three months ended March 31, 2000, as
compared to the same period last year as a result of: (i) ATM surcharges; (ii)
interest income on Bank Owned Life Insurance; and (iii) interest from officers'
life insurance.

NON-INTEREST EXPENSE. Compensation expense increased $259,000 as a result of
increased: (i) number of employees; (ii) compensation to existing employees;
(iii) education and training costs; (iv) reduced expense deferrals associated
with loan originations; and (v) 2000 being a leap year which added one
additional day of compensation for hourly paid employees.

Federal insurance premiums decreased $51,000 as a result of a decrease in
federal deposit premiums charged First Northern and other Savings Association
Insurance Fund ("SAIF") insured institutions. Beginning in the year 2000, the
Financing Income Corporation Obligations ("FICO") bonds interest cost was spread
out to all insured financial institutions rather than just the SAIF insured
institutions.

Occupancy expense increased 24.5% in the first quarter of 2000 as a result of
the Savings Bank's rental of approximately 14,000 square feet of office space in
downtown Green Bay. This rental space consolidated various operational
departments in one location that were in three separate Savings Bank offices.

Data processing expense increased $12,000 in the three months ended March 31,
2000, as a result of an increase in service bureau expense and service contracts
on data processing equipment. Service bureau expense increased as a result of
increased contract cost, additional transactions processed and additional
products offered.


                                    FN-93

<PAGE>   277


Furniture and equipment expense increased $9,000 in the first quarter of 2000 as
a result of increased cost of service contracts on equipment and increased
depreciation on furniture and equipment at the remodeled Kiel Office.

Marketing expense decreased $10,000 in the first quarter of 2000 primarily as a
result of timing of the marketing expense. It is anticipated marketing expenses
will increase in the second quarter of 2000 as compared to the first quarter of
2000.

Other expenses increased $73,000 in the three months ended March 31, 2000, as a
result of: (i) debit card expenses; (ii) costs associated with the operation of
SFC and (iii) employees expense.


INCOME TAXES. The effective income tax rate for the first quarter of 2000 was
32.4% as compared to 34.0% for the first quarter of 1999. The decrease in the
effective income tax rate was the result of the purchase of BOLI and an increase
in the earnings of FNII, which is not subject to state income taxes. Since First
Northern intends to hold the life insurance policies until the participants'
death, BOLI interest income is not taxable. In addition, First Northern moved
its indirect automobile loan portfolio to FNII at the beginning of the second
quarter of 1999, which has reduced state income taxes. In March 1999, First
Northern moved approximately $56.3 million in mortgage loan participations to
FNII and further reduced its state income tax.


LEGISLATION. The Gramm-Leach-Bliley Act ("Act") passed by Congress could
significantly alter the environment in which First Northern and the Savings Bank
operate. This Act tore down the former artificial statutory barriers between
financial institutions, insurance companies, and investment firms and may lead
to increased competition among such entities. In addition, the Act will prevent
the sale of unitary thrift holding companies, such as First Northern, to
commercial companies. Finally, the Act placed additional obligations on First
Northern and the Savings Bank in the areas of customer privacy, CRA-related
agreements, and the operation of ATMs.

                         LIQUIDITY AND CAPITAL RESOURCES

LIQUIDITY

Historically, federal regulations have required the Savings Bank to maintain a
minimum percentage of liquid assets to net withdrawable accounts plus short-term
borrowings. The required percentage (liquidity ratio) has varied from time to
time based upon economic conditions and deposit flows. The liquidity ratio is
set by the Office of Thrift Supervision ("OTS") and it is currently 4% of
average of net withdrawable accounts plus short-term borrowings payable on
demand or in one year or less during the current calendar quarter. In general,
liquid assets, for the purposes of calculating the liquidity ratio, include
cash, certain time deposits, and U.S. government and agency obligations. The
Savings Bank has historically maintained a liquidity ratio that exceeds the OTS
requirement. The Savings Bank's quarterly average liquidity ratio at March 31,
2000, was 5.20%. At December 31, 1999, its monthly average liquidity ratio was
5.45%. The slight decrease in the liquidity ratio at March 31, 2000, is mainly
attributable to the growth in the loan portfolio. The Savings Bank believes that
its maintenance of excess liquidity, above the 4% federally required liquidity
ratio, is an appropriate strategy to aid in proper asset/liability management.

Liquidity management is both a daily and long-term responsibility of management.
The Savings Bank adjusts its investments in liquid assets based upon
management's assessment of: (i) expected loan demand; (ii) expected deposit
flows; (iii) yields available on interest-earning deposits; and (iv) the
objectives of its asset/liability management program. Excess liquidity is
invested generally in interest-earning overnight deposits and other short-term
government and agency obligations. When the Savings Bank requires funds beyond
its ability to generate them internally, it can borrow funds from the FHLB of
Chicago or other sources. The FHLB of Chicago limits advances to member
institutions to an aggregate amount not to exceed 35% of the member
institution's total assets. Wisconsin law permits First Northern, without the
prior written approval of the Wisconsin Department of Financial Institutions ---
Division of Savings Institutions, to borrow an aggregate amount not to exceed
50% of its total assets.

CAPITAL RESOURCES AND REGULATORY INFORMATION

First Northern's net worth to total assets ratio at March 31, 2000, for State of
Wisconsin regulatory requirements was 8.6%, or 2.6% over the Wisconsin minimum
legal requirement of 6.00% of total assets established by the Division of
Savings Institutions of the Department of Financial Institutions, which
regulates First Northern.

As of March 31, 2000, the most recent notification from the 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 tangible, core and risk based ratios as set forth in the
following table. As a state-chartered savings institution, the Savings Bank is
also subject to a minimum capital requirement of the State of Wisconsin.
Management believes that, at March 31, 2000, the Savings Bank exceeded all
capital adequacy requirements to which it is subject. There are no conditions or
events since that notification that management believes have changed the Savings
Bank's categorization as well capitalized.

ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Bank Mutual will be incorporated under federal law, and indemnification
of its directors will be governed by federal law, and OTS regulations
thereunder. Federal regulations define areas for indemnity coverage by federal
savings banks, such as Mutual Savings (the "Bank") as follows:

         (a) Any person against who any action is brought or threatened because
that person is or was a director or officer of the Bank shall be indemnified by
the Bank, as the case may be, for:

                    (i)  Any amount for which such person becomes liable under a
             judgment in such action; and

                    (ii) Reasonable costs and expenses, including reasonable
             attorney's fees, actually paid or incurred by such person in
             defending or settling such action, or in enforcing his or her
             rights to indemnification if the person attains a favorable
             judgment in such enforcement action, which may be advanced in
             certain instances.

         (b) Indemnification provided for in subparagraph (a) shall be made to
such officer or director only if the requirements of this paragraph are met:

                    (i) The Bank shall make the indemnification provided by
             subparagraph (a) in connection with any such action which results
             in a final judgment on the merits in favor of such officer or
             director.



                                      II-1


<PAGE>   282



                    (ii) The Bank shall make the indemnification provided by
             subparagraph (a) in case of settlement of such action, final
             judgment against such director or officer or final judgment in
             favor of such director or officer other than on the merits, if a
             majority of the disinterested directors of the Bank determines that
             such a director or officer was acting in good faith within the
             scope of his or her employment or authority as he or she could
             reasonably have believed under the circumstances was in the best
             interest of the Bank or its members.

         (c) As used in this paragraph:

                    (i) "action" means any judicial or administrative
             proceeding, or threatened proceeding, whether civil, criminal, or
             otherwise, including any appeal or other proceeding for review;

                    (ii) "final judgment" means a judgment, decree, or order
             which is not appealable and as to which the period for appeal has
             expired with no appeal taken:

                    (iii) "settlement" includes the entry of a judgment by
             consent or by confession or a plea of guilty or nolo contendere.

         Regulations promulgated by the OTS subject Bank Mutual to the same
indemnification regulations applicable to the Bank as described above.

         The Bank has a directors and officers liability policy providing for
insurance against certain liabilities incurred by directors and officers of the
Bank while serving in their capacities as such, and Bank Mutual and the MHC will
continue coverage, which is intended to be increased to reflect Bank Mutual's
status as a publicly-traded company.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

         Not Applicable.

ITEM 26. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.

         See the Exhibit Index following the Signatures page in this
Registration Statement, which Exhibit Index is incorporated herein by reference.

ITEM 22. UNDERTAKINGS.

         Bank Mutual hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this Registration Statement:

             (i)  To include any prospectus required by Section 10(a)(3) of the
                  Securities Act of 1933;

             (ii) To reflect in the prospectus any facts or events arising after
                  the effective date of the Registration Statement (or the most
                  recent post-effective amendment thereof) which, individually
                  or in the aggregate, represent a fundamental change in the
                  information set forth in the Registration Statement.
                  Notwithstanding the foregoing, any increase or decrease in
                  volume of securities offered (if the total dollar value of
                  securities offered would not exceed that which was registered)
                  and any deviation from the low or high end of the estimated
                  maximum offering range may be reflected in the form of
                  prospectus filed with the Commission pursuant to Rule 424(b)
                  if, in the aggregate, the changes in volume and price
                  represent no more than a 20% change in the maximum aggregate


                                      II-2


<PAGE>   283



                   offering price set forth in the "Calculation of Registration
                   Fee" table in the effective Registration Statement; and

             (iii) To include any material information with respect to the plan
                   of distribution not previously disclosed in the registration
                   statement or any material change to such information in the
                   registration statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
Registration Statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         (4) That every prospectus: (i) that is filed pursuant to paragraph (5)
immediately preceding, or (ii) that purports to meet the requirements of Section
10(a)(3) of the Act and is used in connection with an offering of securities
subject to Rule 415, will be filed as a part of an amendment to the Registration
Statement and will not be used until such amendment is effective, and that, for
purposes of determining any liability under the Securities Act of 1933, each
such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         (5) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions referred to in Item 20 of
this Registration Statement, or otherwise, Bank Mutual has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by Bank Mutual of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, Bank Mutual will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
