These financial statements are the responsibility of the Plan'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 net assets available for benefits of the Plan as of December 31, 2001 and 2000, and the changes in its net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes as of December 31, 2001, is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Participants should refer to the Plan Agreement for a more complete description of the Plan's provisions. GENERAL The Plan is a defined contribution 401(k) retirement savings plan covering substantially all employees of First Northern Savings Bank and its wholly owned subsidiaries (the "Bank") (a wholly owned subsidiary of Bank Mutual Corporation) who have been employed for one year and are 21 years of age. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974. The Plan is administered by certain officers of the Bank. EMPLOYEE CONTRIBUTIONS Participants may elect to defer a portion of their cash compensation (up to the lesser of 15% of annual compensation or $10,500 in 2001 and 2000) and contribute this amount to the Plan. Amounts contributed are deducted from gross wages for each payroll period and are remitted to the Plan in accordance with the investment options selected by the participant. EMPLOYER CONTRIBUTIONS The Bank makes matching contributions equal to 50% of the employee's contributions. Employee contributions over 4% of annual cash compensation are not matched. Matching contributions are funded at each payroll date along with employee contributions. The Bank also makes an annual contribution equal to 3% of each qualified participant's annual cash compensation. In addition, the Bank, at its discretion, may make certain additional contributions as determined by the Board of Directors of the Bank. The additional contribution is equal to 3.75% and 2.50% of each qualified participant's annual cash compensation at December 31, 2001 and 2000, respectively. PARTICIPANTS' ACCOUNTS Each participant's account is credited with the participant's contributions, the Bank's matching, annual and discretionary contributions, and plan earnings (based on participant's investment election and account balance). 4 FIRST NORTHERN SAVINGS BANK 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- NOTE 1 PLAN DESCRIPTION (Continued) PARTICIPANT LOANS Participants may borrow from their fund accounts a minimum of $1,000 to a maximum equal to the lesser of $50,000 or 50% of their vested account balance. Loan terms range from one to five years. The loans are secured by the balance in the participant's account and bear interest at a rate commensurate with similar type loans made by the Bank. Principal and interest are paid ratably through monthly payroll deductions. VESTING All employee contributions are 100% vested immediately. Employer contributions vest at 25% after two years of service, 50% after three years of service, and 100% after four years of service. In addition, there is full vesting upon normal retirement at age 65, death, or disability. Amounts forfeited are aggregated and used to offset future employer contributions. EXPENSES OF THE PLAN Administrative expenses charged by Principal Mutual Life Insurance Company, investment advisory fees, and substantially all other expenses incurred in conjunction with the Plan are paid by the Bank. Certain administrative expenses and withdrawal charges are paid out of plan assets. PAYMENT OF BENEFITS Plan benefits are available at normal retirement, deferred retirement, early withdrawal, disability retirement, death, or termination of employment. Participants may elect to receive benefit payments in the form of a lump-sum distribution or in installments. PLAN TERMINATION The Bank has reserved the right to terminate the Plan at any time. In the event of termination, all amounts credited to participants' accounts will be distributed to participants in accordance with the Plan's provisions. 5 FIRST NORTHERN SAVINGS BANK 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- NOTE 2 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES METHOD OF ACCOUNTING The accounting records of First Northern Savings Bank 401(k) Savings Plan are maintained on the accrual basis of accounting in accordance with generally accepted accounting principles. USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS The preparation of the accompanying financial statements in conformity with generally accepted accounting principles requires the plan administrator to make estimates and assumptions that affect certain reported amounts and disclosures. Actual results may differ from these estimates. INVESTMENT VALUATION Investments are stated at fair value. Investments in the Principal Financial Group's Pooled Separate Accounts are carried at fair value which represents the quoted market price of the underlying investments. For investments in securities which do not have an established market, the trustee of the Plan establishes a fair value. The Guaranteed Interest Accounts include funds under group annuity contracts. The contracts are stated at fair market value, which is determined by adjusting the contract value for differences between the current market interest rate and the interest rate on the account. The fair value of Bank Mutual Corporation's common stock is its quoted market price. Security transactions are accounted for on the trade-date basis (the date the order to buy or sell is executed). Both realized and unrealized appreciation or depreciation is reflected for the year in the statement of changes in net assets available for benefits. Gains or losses on security transactions are recorded as the difference between proceeds received and the carrying value of the investments. Interest income is recognized on the accrual method, and dividend income is recorded on the ex-dividend date. 6 FIRST NORTHERN SAVINGS BANK 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- NOTE 3 INVESTMENTS The following is a schedule of investments that individually represents 5% or more of the Plan's net assets at December 31: 2001 2000 -------------------------------- ----------------------------------- ASSET FAIR PERCENT OF ASSET FAIR PERCENT OF VALUE NET ASSETS VALUE NET ASSETS ---------------------------------------------------------------------------------------------------------------- Principal Stable Value Account $682,672 5.8 $554,428 5.1 Principal Small Company Blend Account 1,552,519 13.1 1,331,181 12.3 Principal Large Company Blend Account 1,589,459 13.4 1,893,113 17.5 Principal Small Company Growth Account 741,286 6.2 732,641 6.8 Principal Medium Company Growth Account 903,345 7.6 1,063,064 9.8 Principal Large Company Growth Account 949,809 8.0 1,286,974 11.9 Bank Mutual Corporation Common Stock 3,218,106 27.1 1,786,550 16.5 During 2001 and 2000, the Plan's investments (including investments bought or sold during the year as well as those held at the end of the year) appreciated (depreciated) as follows: 2001 2000 ---------------------------------------------------------------------------------------------------------- Pooled Separate Accounts ($1,043,775) ($607,784) First Northern Capital Corporation Stock 0 1,874,923 Bank Mutual Corporation Stock 1,134,458 (98,177) ---------------------------------------------------------------------------------------------------------- Net appreciation $90,683 $1,168,962 ========================================================================================================== 7 FIRST NORTHERN SAVINGS BANK 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS - -------------------------------------------------------------------------------- NOTE 4 TRANSACTIONS WITH PARTIES-IN-INTEREST First Northern Savings Bank serves as the sponsor of the Plan.
