3 PERSONS MAKING THE SOLICITATION The proxy is being solicited by the Corporation's Board of Directors and will be voted in favor of the Directors' recommendations on each and all matters properly brought before the meeting, unless the undersigned shareholder specifically instructs the holder or holders of the proxy to the contrary. With regard to the election of directors, votes may be cast in favor or withheld; votes that are withheld will be excluded entirely from the vote and will have no effect. Abstentions may be specified on all proposals submitted to shareholders (other than the election of directors). Abstentions and "broker non-votes" are counted for purposes of determining the presence or absence of a quorum for the transaction of business. Under the rules of the New York Stock Exchange, Inc., brokers who hold shares in street name for customers may have authority to vote on certain items when they have not received instructions from beneficial owners. A "broker non-vote" occurs on an item submitted for shareholder approval when the broker does not have authority to vote on the item in the absence of instructions from the beneficial owner. Such "broker non-votes" will have no effect on the outcome of the election of directors. The approval of a majority of the votes cast on a particular matter shall be an act of the shareholders.

The non-contributory benefits were frozen as of December 31, 1996. The Plan is integrated with Social Security. The following table presents the non-contributory benefits payable for life under the Plan to employees assuming normal retirement in the current year. AVERAGE HIGH NON-CONTRIBUTORY PENSION BASED ON 5-YEAR ANNUAL YEARS OF CREDIT SERVICE COMPENSATION 10 YEARS 20 YEARS 25 YEARS 30 YEARS 40 YEARS $ 50,000 $ 9,346 $17,537 $19,100 $20,620 $23,856 75,000 14,546 27,359 29,967 32,425 37,354 100,000 19,746 37,181 40,834 44,231 50,852 150,000 30,146 56,825 62,568 67,841 77,847 The values reflected in the table represent the application of the Plan formula to the appropriate amounts of compensation and years of service. Benefits payable under the Plan, however, must be in compliance with the applicable guidelines or maximum prescribed in the Internal Revenue Code and in the Employee Retirement Income Security Act of 1974 (ERISA), as currently stated or as adjusted from time to time. As of December 31, 1996, the credited years of service for each of the Corporation's executive officers named in the Summary Compensation Table is as follows: Mr. Batten 27 years; Mr. Joyce 6 years; and Mr. Melik 29 years. Mr. Feiertag and Mr. Fabry are not eligible for an accrued benefit under the Plan.

10 Effective January 1, 1997, the Plan was amended to add a cash balance formula for post-January 1, 1997, accruals. Benefits under the Plan are generally equal to the sum of the benefits as frozen on December 31, 1996, plus benefits that accumulate under the cash balance formula beginning on January 1, 1997. Benefits under the cash balance formula are generally stated as a lump sum amount, but may be distributed as a lump sum or an annuity. Accruals under the cash balance formula are based on a percentage of compensation, from 4.5% to 6.5% based on years of service, with interest credits at the thirty-year U.S. Treasury Bond rate with a minimum guaranty of 3%. To record these pay credits and interest credits, a hypothetical account balance is maintained for each participant. The hypothetical account balance for each named executive as of June 30, 2003, is as follows: Mr. Batten $90,553; Mr. Joyce $67,776; Mr. Melik $78,789; and Mr. Feiertag $24,461. If the named executives continue in their respective positions and retire at the normal retirement age of 65, their estimated annual pension amount under cash balance portion of the Plan would be: Mr. Batten $3,059; Mr. Joyce $8,176; Mr. Melik $12,042; and Mr. Feiertag $25,176. Supplemental Retirement Benefit Plan A supplemental retirement benefit is extended to qualified management. The supplemental retirement benefit is calculated as a single life annuity at an amount approximating 50% of the highest rate of pay attained during a specified period. The benefit is payable in the form of a single life annuity, contingent annuity, 10-year temporary annuity, a single lump sum payment, or two payments. The contingent annuity provides for payments to continue to the surviving spouse at a rate equal to 50% of the rate previously paid to the participant. In the event of death of a plan member after attaining a retirement age but prior to retirement, the surviving spouse will receive a lump sum benefit. Compensation of Directors Outside Directors of the Corporation (non-corporation employees) are paid an annual retainer of $10,000. In addition, outside Directors receive a $1,500 fee for each board meeting and each committee meeting attended and $3,000 per year for serving as a committee chairman. Directors who are officers do not receive any fees in addition to their remuneration as officers. Outside Directors (non-Corporation employees) are eligible to participate in the 1988 Non-Qualified Stock Option Plan for Officers, Key Employees and Directors and the 1998 Stock Option Plan for Non-Employee Directors. Under the 1998 Plan, each outside Director receives 1,000 options upon election or re-election at an annual meeting and 600 options if appointed to the Board between annual meetings. Outside Directors (non-Corporation employees) who reach the age of 68 or who retire from full-time employment maybe required to retire from the Board of Directors effective as of the completion of their current term. Retired outside directors are entitled to an annual retirement benefit equal to the sum of: a) The annual retainer at the time of retirement. b) 6 monthly fees for Director Meetings at the rate prevailing at the time of retirement. The benefit is payable for a term equal to the Director's years of service or life, whichever is shorter. Employment Contracts The Corporation has entered into agreements with certain of its key executives, including Messrs. Batten, Joyce, Melik and Feiertag. The agreements provide for severance benefits to be paid to the executive following a change in control of the Corporation (as defined in those agreements) and a termination (as defined in those agreements) of the employment of the executive. Upon the occurrence of the events, as specified in the agreements, which would entitle the executive to the payment of severance benefits, the maximum contingent liability of the Corporation for the payment of such severance benefits would be approximately $3,187,000. Severance benefits for an executive officer would generally consist of the sum of the executive's highest annual base salary between the change in control and the date of termination plus the executive's most recent annual bonus times the lesser of 1.50 (2.75 for Messrs. Batten and Joyce) or the number of whole and fractional years between the termination date and his normal retirement date. In addition, the executive would be entitled to the cash value of any shares of common stock subject to unexercised stock options held by the executive and a continuance of fringe benefits for 24 months following termination. The agreements are specifically designed to assure that benefits will not exceed the limitations and provisions of Sec. 280(g) of the Internal Revenue Code.

11 Retention and Non-Compete Agreement During fiscal 2003, Mr. Joyce and the Company entered into a Retention and Non-Compete Agreement. Under the agreement, Mr. Joyce agrees to continue as President and Chief Operating Officer until age 65 or earlier with consent of the Chief Executive Officer. In consideration for the above, Twin Disc, Incorporated will pay Mr. Joyce a retention bonus of $300,000 upon his attaining the age of 65. The entire bonus is payable in the event of an involuntary termination and a pro-rated retention bonus is payable in the event of death or disability. In addition, Mr. Joyce has agreed to a three-year non-disclosure and non-compete agreement. Board Compensation Committee Report on Executive Compensation Compensation Philosophy The Corporation's primary business objective is to maximize shareholder value over the long term. To accomplish this objective, the Corporation has developed a comprehensive business strategy that emphasizes maximizing long-term cash flow and earnings, maintaining leadership or becoming the leader in its markets, and providing products of the highest quality. The Compensation Committee of the Board of Directors (the "Committee") is comprised of 3 independent directors, none of whom has interlocking or other relationships which might be considered conflicts of interest. The Committee establishes compensation programs which are designed to foster the Corporation's business objectives. The Committee approves the design of, assesses the effectiveness of, and administers executive compensation programs in support of compensation policies. Committee members believe that the compensation program should target compensation levels at rates that are reflective of current market practices. Offering market-comparable pay opportunities allows the Corporation to maintain a stable, successful management team. Competitive market data is provided by an independent compensation consultant. The data provided compares the Corporation's compensation practices to a group of comparative companies. The Corporation's market for compensation comparison purposes is comprised of a group of companies that have national and international business operations and similar sales volumes, market capitalizations, employment levels, and lines of business. In establishing a comparative group for compensation purposes, the Committee exercises its judgment and makes its decision after considering the factors it deems relevant. The companies chosen for the comparative group used for compensation purposes are not necessarily the same companies which comprise the peer group index in the Performance Graph included in this proxy statement. The Committee believes that the Corporation's most direct competitors for executive talent include many companies in geographical areas in which the Corporation operates as well as many of the companies that are included in the peer group established for comparing shareholders returns. The key elements of the Corporation's executive compensation are base salary, annual incentives, long-term compensation, and benefits. These key elements are addressed separately below. In determining compensation, the Committee considers all elements of an executive's total compensation package, including severance plans, insurance, and other benefits, with the objective of being competitive but not trend setting. Base Salaries The Committee regularly reviews each executive's base salary. Base salary ranges are targeted at market levels, based upon the Committee's analysis of marketplace practices. Base salaries for executives are initially determined by evaluating executives' levels of responsibility, prior experience, breadth of knowledge, internal equity issues, and external pay practices. Base salaries offer stability to executives and allow the Corporation to attract competent executive talent and maintain an effective management team. They also allow executives to be rewarded for individual performance based on the Corporation's evaluation process which encourages the development of executives. Pay for individual performance rewards executives for achieving goals which may not be immediately evident in common financial measurement.

12 Increases to base salaries are driven primarily by individual performance. Individual performance is evaluated based on sustained levels of individual contribution to the Corporation. When evaluating individual performance, the Committee considers the executive's effort in promoting Corporate values; improving product quality; developing relationships with customers, suppliers, and employees; demonstrating leadership abilities among coworkers; and other goals. Overall, executive salaries were increased at rates comparable to the increases provided at other companies and are near market levels. As reflected in the Summary Compensation Table on page 8, Mr. Batten's base salary was increased in fiscal year 2003 by 4.1% or $16,507. It was later reduced by 10% or $39,500, effective for fiscal 2004, as part of a corporate- wide cost reduction program. In determining Mr. Batten's base salary in 2003, the Committee considered the Company's financial performance for the year, Mr. Batten's individual performance, and his long-term contributions to the success of the Corporation. The Committee also compared Mr. Batten's base salary to the base salaries of CEOs at comparative companies. Annual Incentives The Twin Disc Annual Incentive Bonus Program promotes the Corporation's pay-for-performance philosophy by providing executives with direct financial incentives in the form of annual cash bonuses for achieving corporate, business unit, and individual performance goals. The annual incentive bonus program allows the Corporation to communicate specific goals that are of primary importance during the coming year and motivate executives to achieve these goals. Eligibility to participate in the Annual Plan, as well as the individual payout percentages assigned to each eligible executive's position, are determined annually by Mr. Batten, as chief executive officer, subject to the approval of the Committee. Each year, the Committee approves specific goals relating to each executive's bonus opportunity. Eligible executives are assigned threshold, target, and maximum bonus levels based on a percentage of base salary. Executives earn bonuses to the extent to which pre-established performance goals are achieved. Target bonus awards are established at levels approximating marketplace practices for each executive. Targets are considered by the Committee to be achievable, but to require above average performance from each of the executives. Corporate performance goals in 2003 were based on target earnings and return on net assets employed. There were no bonus awards in fiscal year 2003 as performance goals were not attained. Long-Term Incentives Long-term incentive opportunities are provided pursuant to the Corporation's 1988 Non-Qualified Stock Option Plan for Officers, Key Employees and Directors; the 1988 Incentive Stock Option Plan, the 1998 Incentive Compensation Plan; and the 1998 Stock Option Plan for Non-Employee Directors. In keeping with the Corporation's commitment to provide a total compensation package which includes at-risk components of pay, the Committee makes annual decisions regarding appropriate stock option grants for each executive. When awarding stock options, the Committee considers executives' levels of responsibility, prior experience, historical award data, various performance criteria, and compensation practices at comparator companies. Consistent with the above stated goals, Mr. Batten received 8,000 options to purchase shares in fiscal year 2003. Stock options are granted at an option price not less than the fair market value of the Corporation's common stock on the date of grant. Accordingly, stock options have value only if the stock price appreciates from the date the options are granted. This design focuses executives on the creation of shareholder value over the long term and encourages equity ownership in the Corporation. Section 162(m) of the Internal Revenue Code, enacted in 1993, generally disallows a tax deduction to public companies for compensation over $1 million paid to the Company's CEO and four other most highly compensated executive officers. Qualifying performance-based compensation will not be subject to the deduction limit if certain requirements are met. The compensation of the Corporation's CEO and the four other most highly compensated executive officers currently does not approach the disqualifying threshold. In the future, in the event the disqualifying threshold becomes an issue, the Committee will weigh all the facts and circumstances in existence at the time. Compensation Committee David L.

13 The following Report of the Audit Committee does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Company filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent the Company specifically incorporates this report by reference therein. Audit Committee Report The charter reflects standards set forth in SEC regulations and New York Stock Exchange rules. All members of the Audit Committee are independent, as defined in Sections 303.01(B)(2)(a) and (3) of the listing standards of the New York Stock Exchange. The Committee has implemented procedures to ensure that during the course of each fiscal year it devotes the attention that it deems necessary or appropriate to each of the matters assigned to it under the Committee's charter. To carry out its responsibilities, the Committee met four times during fiscal 2003. As part of its responsibilities, and as set forth in its charter, the Audit Committee met with both management and the Corporation's independent accountants to review and discuss the audited financial statements prior to their issuance and to discuss significant accounting issues. Management advised the Committee that all financial statements were prepared in accordance with generally accepted accounting principles, and the Committee discussed the statements with both management and the independent accountants. The Committee's review included discussion with the independent accountants of matters required to be discussed pursuant to Statement on Auditing Standards No. 61 (Communication with Audit Committee). The Committee received the written disclosures and the letter required from the independent accountants as required by the Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committee). The Committee also discussed with PricewaterhouseCoopers LLP matters relating to its independence. On the basis of these reviews and discussions, the Committee recommended to the Board of Directors that the Board approve the inclusion of the Corporation's audited financial statements in the Corporation's Annual Report on Form 10-K for the fiscal year ended June 30, 2003, for filing with the Securities and Exchange Commission. Audit Committee David R. Zimmer, Chairman Paul J. Powers David B. Rayburn George E.

14 CORPORATE PERFORMANCE GRAPH The following table compares total shareholder return over the last 5 fiscal years to the Standard & Poor's Machinery Index and the Russell 2000 index. The S&P Machinery Index consists of a broad range of manufacturers. The Russell 2000 Index consists of a broad range of 2,000 Companies. The Corporation believes, because of the similarity of its business with those companies contained in the S&P Machinery Index, that comparison of shareholder return with this index is appropriate. Total return values for the Corporation's common stock, the S&P Machinery Index and the Russell 2000 Index were calculated based upon an assumption of a $100 investment on June 30, 1998 and based upon cumulative total return values assuming reinvestment of dividends on a quarterly basis.
