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 the standards of the Public Company Accounting Oversight Board (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, 2004 and 2003 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 of America. Our audit was conducted 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-December 31, 2004, 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. This supplemental schedule is the responsibility of the Plan's manangement. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

Basis of Presentation and Significant Accounting Policies ------------------------------------------------------------- General ------- The following brief description of the Twin Disc, Incorporated - Accelerator 401(k) Savings Plan (the "Plan") is provided for general information purposes only. Participants should refer to the plan agreement for a more complete description of the Plan's provisions. The Plan, established April 1, 1986, is a defined contribution plan covering substantially all Twin Disc, Incorporated (the "Company") domestic employees and is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). Eligibility ----------- An employee of the Company is eligible for plan participation after completing two months of employment. Contributions ------------- Participants may elect to contribute on a pre-tax basis up to 100% of annual gross income with contributions limited under provisions of the Internal Revenue Code. For participants who are employed by Twin Disc, Inc., the Company contributes an amount equal to a percentage of each participant's 401(k) contributions, up to 6% of compensation. The contribution percentage for the years ended December 31, 2004 and 2003 was 50%. For participants who are employed by the Twin Disc South East subsidiary, the Company contributes a matching contribution equal to 25% of each participant's 401(k) contributions, up to 6% of compensation, and a profit sharing contribution equal to 2.5% of each participant's compensation. The Internal Revenue Code has set a maximum of $13,000 and $12,000 for tax-deferred contributions that may be excluded for any individual participant in 2004 and 2003, respectively. The Internal Revenue Code also allows additional catch-up contributions for participants age fifty and over. The maximum additional contribution allowed was $3,000 and $2,000 in 2004 and 2003, respectively. No federal income tax is paid on the tax-deferred contributions and growth thereon until the participant withdraws them from the Plan. The Plan enables participants to allocate their contributions and account balances among various investment options offered by the Plan. Assets of the Plan are segregated and invested based upon the total allocation of the participants' accounts. Participants may direct such allocations in any whole percentage increment and allocations can be changed at any time. Vesting ------- Participants are immediately 100% vested in their individual account balances. Withdrawals ----------- After-tax contributions may be withdrawn at any time upon receipt of written notice by the Trustee. Pre-tax contributions may only be withdrawn, prior to employment termination, in the event of severe financial hardship or once annually upon attainment of age 59 1/2. A final distribution is paid to the participant upon termination of employment with the Company. Final distributions in excess of $5,000 may be deferred as elected by the participant until age 70 1/2. 6 TWIN DISC, INCORPORATED - ACCELERATOR 401(k) SAVINGS PLAN Racine, Wisconsin Notes to Financial Statements December 31, 2004 and 2003 (Continued) 1. Basis of Presentation and Significant Accounting Policies (Continued) ------------------------------------------------------------------------- Participant Accounts -------------------- On March 1, 2004, the Company authorized the transfer of trusteeship of the Plan from UMB Bank, N.A., to T. Rowe Price Trust Company, and the recordkeeping services for the Plan from Strong Retirement Plan Services ("Strong") to T. Rowe Price Retirement Plan Services Inc. ("T. Rowe Price"). T. Rowe Price maintains individual accounts for each participant for their respective investment in each of twelve available investment funds. For all investment programs which are mutual funds or collective trust funds, participant balances are maintained on a share or unit method, as appropriate. Participant investments in the Twin Disc, Inc. Stock Fund, a unitized fund in 2003, were accounted for on a unit value method. The participant investments were accounted for on a share method beginning March 1, 2004. Shares and share values, and units and unit values for the fund as of December 31, 2004 and 2003 were as follows: Shares/Units Share/Unit Value December 31, December 31, ---------------- ---------------- 2004 2003 2004 2003 ---- ---- ---- ---- Twin Disc, Inc. Stock 51,236 --- $25.55 --- Twin Disc, Inc. Stock Fund --- 81,285 --- $12.05 Participant Loans ----------------- Participants may be granted a loan against their individual account balance limited to the lesser of $50,000 or 50% of the account balance. Loans are granted in a uniform and nondiscriminatory manner based on the loan policy as set forth by the Benefits Committee. The loan proceeds are made pro-rata from the investment elections of the participant. Each participant's individual account and the interest and principal paid on the loan shall be credited only to such participant's account balance. Any such loan shall be repaid over a period not exceeding five years unless the loan is used to purchase a principal residence, in which case the loan shall be repaid over a period not exceeding fifteen years. Basis of Accounting ------------------- The financial statements of the Plan are prepared under the accrual method of accounting. Administrative Expenses ----------------------- Certain administrative expenses of the Plan are paid by the Company at its discretion. The remaining administrative expenses are paid by the Plan. Benefit Payments ---------------- Benefits are recorded when paid. 7 TWIN DISC, INCORPORATED - ACCELERATOR 401(k) SAVINGS PLAN Racine, Wisconsin Notes to Financial Statements December 31, 2004 and 2003 (Continued) 1. Basis of Presentation and Significant Accounting Policies (Continued) ------------------------------------------------------------------------- Investment Valuation -------------------- Investments of the Plan are stated at fair value. The values of investments in mutual funds and common stocks are determined by the last reported market price on the last business day of the year. Investments in collective trust funds, other than the T. Rowe Price Stable Value Common Trust Fund (see below), are valued at redemption prices established by the trustee of the funds based on the quoted market prices of the underlying investments. Participant loans are valued at cost which approximates fair value. The Plan presents in the statement of changes in net assets, the net appreciation (depreciation) in the fair value of its investments, which consists of the realized gains or losses and the unrealized appreciation (depreciation) on those investments. Purchases and sales of investments are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. Interest is recognized when earned. The fair value of the T. Rowe Price Stable Value Common Trust Fund is determined by T. Rowe Price Retirement Plan Services, Inc. The fair value of the Strong Stable Value Fund was determined by Strong Investments, Inc. The collective trust fund invests in short-term and long-term conventional and synthetic investment contracts issued by insurance companies and other institutions that meet the high credit quality standards established by Strong and T. Rowe Price. The investment contracts are recorded at contract value (which represents contributions received, plus interest, less plan withdrawals), which approximates fair value at December 31, 2004. 2.

Income Tax Status --------------------- The Plan obtained its latest determination letter on March 19, 2002, in which the Internal Revenue Service stated the Plan as then designed, was in compliance with the applicable requirements of the Internal Revenue Code. The Plan administrator and the Plan's tax counsel believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the Internal Revenue Code. Therefore, no provision for income taxes has been included in the Plan's financial statements. 4. Termination of Plan ----------------------- Although the Company has not expressed any intent to terminate the Plan, it may do so at any time. 5. Party-in-Interest Transactions ---------------------------------- Transactions involving employer securities, funds administered by T. Rowe Price Trust Company, the current trustee of the Plan, funds administered by T. Rowe Price Retirement Plan Services, Inc., the recordkeeper of the Plan, and participant loans are considered party-in-interest transactions. These transactions are not, however, considered prohibited transactions under 29 CFR 408(b) of the ERISA regulations. 6. Amounts Allocated to Withdrawn Participants ----------------------------------------------- Plan assets of $9,086,930 and $8,608,508 have been allocated to the accounts of persons who are no longer active participants of the Plan as of December 31, 2004 and 2003, respectively, but who have not yet received distributions as of that date. 7. Use of Estimates -------------------- The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of additions and deductions during the reporting periods. Actual amounts could differ from those estimates. 9 8. Risks and Uncertainties --------------------------- The Plan's investments are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risk associated with certain investments and the level of uncertainty related to changes in the values of investments, it is at least reasonably possible that changes in risks in the near term would materially affect participants' account balances and the amounts reported in the Statements of Net Assets Available for Benefits and the Statements of Changes in Net Assets Available for Benefits.
