achieves a specified consolidated sales revenue objective in the fiscal year
ending June 30, 2008.  A copy of the form of the Performance Stock Award
Agreement is attached hereto as Exhibit 10.1 and is incorporated herein by

At its meeting on January 20, 2006, the Board of Directors of the Company

amendments to the Company's 2004 Stock Incentive Plan (the "Plan").  The
amendments to the Plan, which are subject to approval by the Company's
shareholders at the Company's 2006 annual meeting, permit the Compensation
Committee to make Performance Stock Unit Awards (i.e., the right to receive
cash payments equal to the fair market value of the Company's common stock as
of the date such payments vest, if specified performance goals are achieved)
and Performance Unit Awards (i.e., the right to receive predetermined cash
payments if specified performance goals are achieved).  The amendments also
place limitations on the maximum annual awards or payments under the Plan to
any particular individual in order to maximize the Company's ability to deduct
payments under the Plan.  A copy of the amended Plan, which has been renamed
the Twin Disc, Incorporated, 2004 Long-Term Incentive Compensation Plan, is
attached hereto as Exhibit 10.2 and is incorporated herein by reference.

Company, subject to and effective upon Board approval of the amendments to
the Plan.  A total of 23,755 Performance Stock Units were awarded effective

Plan amendments at the Company's 2006  annual meeting of shareholders.  The
Performance Stock Units will vest if the Company achieves a specified

                PERFORMANCE STOCK UNIT AWARD GRANT AGREEMENT

     THIS PERFORMANCE STOCK UNIT AWARD GRANT AGREEMENT (the "Agreement"), by
and between TWIN DISC, INCORPORATED (the "Company") and _______________________
(the "Employee") is dated as of the 20th day of January, 2006, to memorialize
an award of performance stock units of even date herewith.

     WHEREAS, the Company adopted a Stock Incentive Plan in 2004 (the "Plan")
whereby the Compensation Committee of the Board of Directors (the "Committee")
is authorized to grant awards of various types to certain key employees of the
Company; and

     WHEREAS the Company amended the Plan on January 20, 2006, to authorize the
award of performance stock units, which entitle an employee of the Company
receiving such an award to a cash payment equal to the value of the common
stock of the Company if the Company achieves a predetermined performance
objective; and

     WHEREAS, effective January 20, 2006, the Committee made an award of
performance stock units to the Employee as an inducement to achieve the below
described performance objective.

     NOW, THEREFORE, in consideration of the premises and of the covenants and
agreements herein set forth, the parties hereto agree as follows:

     1. Performance Stock Unit Award Grant.  Subject to the terms of the Plan,
a copy of which has been provided to the Employee and is incorporated herein by
reference, the Company has granted Employee an award of _______ performance
stock units effective January 20, 2006.  Such performance stock units entitle
the Employee to receive a cash payment equal to the product of the number of
units multiplied by the fair market value of the Company's common stock as of
June 30, 2008, if the Company achieves at least Two Hundred Fifty Million
Dollars ($250,000,000) in consolidated annual sales revenue in the fiscal year
beginning on July 1, 2007 and ending on June 30, 2008 (the "Performance
Objective"), as reported in its consolidated financial statements for such
fiscal year.  The Committee shall certify whether such Performance Objective
is satisfied before any payment pursuant to a performance stock unit is made.

     2. Price Paid by Employee.  The price to be paid by the Employee for the
performance stock units granted shall be  No  Dollars ($ 0.00) per share.

     3. Voluntary Termination of Employment Prior to Retirement/Termination
for Cause.  If prior to attaining the Performance Objective an Employee
voluntarily terminates employment prior to the Employee becoming eligible for
normal or early retirement under the Company's defined benefit pension plan
covering the Employee or the employment of an Employee is terminated for cause,
the performance stock units granted to such Employee shall be forfeited.  The
Committee shall conclusively determine whether an Employee was terminated for
cause for purposes of this performance stock unit award.

     4. Death/Disability/Other Termination of Employment Other than Change of
Control of Company.  If prior to attaining the Performance Objective an
Employee dies, becomes permanently disabled, voluntarily terminates employment
after becoming eligible for normal or early retirement under the Company's
defined benefit pension plan covering the Employee, or is terminated for any
reason other than for cause or following a Change in Control of the Company as
described in Section 5 (each a "Qualifying Event"), the performance stock units
granted to such Employee shall be paid on a prorated basis if and when the
Performance Objective is achieved.  Such prorated performance stock unit awards
shall be subject to the following terms and conditions:

   (a) The prorated award shall be determined by multiplying the cash payment
       due pursuant to the vesting of the award by a fraction, the numerator of
       which is the number of days from July 1, 2005, through the Employee's
       last day of employment, and the denominator or which is the number of
       days from July 1, 2005, through June 30, 2008.

   (b) Except as otherwise provided in Section 4(c), the payment of such
       prorated award shall be paid in the ordinary course after the
       determination by the Committee that the Performance Objective has been
       achieved (and no later than 2-1/2 months after June 30, 2007).

   (c) The Committee has the authority in its sole discretion to immediately
       vest the prorated portion of the performance stock units granted
       hereunder of an Employee who experiences a Qualifying Event and to make
       a cash payment pursuant to such prorated awards as if the Performance
       Objective had been fully achieved.  In such event, the calculation of
       the cash payment due to the Employee shall be based on the fair market
 2
       value of the Company's common stock as of the effective date of such
       Employee's termination of employment.

   (d) The Committee shall conclusively determine whether an Employee shall
       be considered permanently disabled for purposes of this performance
       stock unit award.

     5. Change of Control.  Notwithstanding Sections 3 and 4 above, if an event
constituting a Change in Control of the Company occurs and the Employee
thereafter terminates employment for any reason, then the performance stock
units granted hereunder shall immediately vest and a cash payment shall be made
as if the Performance Objective had been fully achieved, regardless of whether
termination of employment is by the Employee, the Company or otherwise.  Such
cash payment shall be equal to the number of performance stock units granted to
the Employee multiplied by the fair market value of the Company's common stock
as of the effective date of such Change in Control.  Employee's continued
employment with the Company, for whatever duration, following a Change in
Control of the Company shall not constitute a waiver of the Employee's rights
with respect to this Section 5.

     For purposes of this Section 5, a "Change in Control of the Company" shall
be deemed to occur in any of the following circumstances:

   (a) if there occurs a change in control of a nature that would be required
       to be reported in response to Item 6(e) of Schedule 14A of Regulation
       14A promulgated under the Securities Exchange Act of 1934, as amended
       (the "Exchange Act")  whether or not the Company is then subject to
       such reporting requirement;

   (b) if any "person" (as defined in Sections 13(d) and 14(d) of the Exchange
       Act) other than Michael Batten or any member of his family (the "Batten
       Family"), is or becomes the "beneficial owner" (as defined in Rule
       13d-3 under the Exchange Act), directly or indirectly, of securities of
       the Company representing thirty percent (30%) or more of the combined
       voting power of the Company's then outstanding securities;

   (c) if during any period of two (2) consecutive years (not including any
       period prior to the execution of this Agreement) there shall cease to
       be a majority of the Board comprised as follows:  individuals who at the
       beginning of such period constitute the Board and any new director(s)
       whose election by the Board or nomination for election by the Company's
       shareholders was approved by a vote of at least two-thirds (2/3) of the
       directors then still in office who either were directors at the
       beginning of the period or whose election or nomination for election was
       previously so approved; or

   (d) if the shareholders of the Company approve a merger or consolidation of
       the Company with any other corporation, other than a merger or
       consolidation which would result in the voting securities of the Company
       outstanding immediately prior thereto continuing to represent (either by
       remaining outstanding or by being converted into voting securities of
       the surviving entity) at least 80% of the combined voting power of the
       voting securities of the Company or such surviving entity outstanding
       immediately after such merger or consolidation, or the shareholders of
       the Company approve a plan of complete liquidation of the Company or an
       agreement for the sale or disposition by the Company of all or
       substantially all the Company's assets.

     6. Awards Contingent Upon Shareholder Approval of Plan Amendments.  All of
the performance stock units granted hereunder are contingent upon the approval
by the Company's shareholders at the Company's 2006 annual meeting of the
amendments to the Plan approved by the Board on January 20, 2006.  Upon the
occurrence of said event, the grant of performance stock units awarded herein
shall be effective as of the date specified herein with no further action
required by the Committee.  If such approval does not occur at the Company's
2006 annual meeting of shareholders, the awards granted hereunder shall be null
and void.

     7. Employment Status.  Neither this Agreement nor the Plan impose on the
Company any obligation to continue the employment of the Employee.

                                ARTICLE I

                                 PURPOSE

   1.1 Purpose.  The purpose of the Twin Disc, Incorporated 2004 Long-Term
Incentive Compensation Plan (the "Plan") is to promote the overall financial
objectives of Twin Disc, Incorporated (the "Company") and its majority owned
subsidiaries ("Subsidiaries") by providing opportunities for the officers and
key employees selected to participate in the Plan (each a "Participant") to
acquire Common Stock of the Company ("Common Stock"), and to receive Common
Stock or cash bonuses upon attainment of specified financial goals of the
Company or its Subsidiaries.  The Plan gives the Compensation Committee of
the Company's Board of Directors, or such other committee as the Board of
Directors shall designate (the "Committee"), the authority and discretion to
award stock options, stock appreciation rights, restricted stock awards,
performance stock awards, performance stock unit awards, performance unit
awards, and/or annual long-term incentive awards (collectively, "Awards") to
eligible employees of the Company.

                                ARTICLE II

	                  EFFECTIVE DATE AND TERM

   2.1 Effective Date.  The Plan shall become effective on the date that it is
approved by a majority of the outstanding shares of Common Stock of the Company
(the "Effective Date"), provided that such approval occurs within twelve months
after the date that the Plan is adopted by the Company's Board of Directors
(the "Board").  The effective date of the 2006 amendments to the Plan (adding
possible grants of performance stock unit awards and performance unit awards,
and making other changes in order to maximize the deductibility of
performance-based awards under Section 162(m) of the Internal Revenue Code)
(the "Code") shall be the date that such amendments are approved by a majority
of the outstanding shares of Common Stock of the Company.

   2.2 Term.  No Award may be granted more than ten years after the Effective
Date.

   2.3 Post-Term Activity.  Awards granted within the term of the Plan as set
forth in Section 2.2, subject to the all other terms and conditions of the Plan
and the agreement(s) governing the grant of the Awards, may be exercised, paid
out, or modified more than ten years after the adoption of the Plan.
Restrictions on Restricted Stock may lapse more than ten (10) years after the
Effective Date.

                                ARTICLE III

                           STOCK SUBJECT TO PLAN

   3.1 Maximum Number.  The maximum number of shares of Common Stock that may
be issued pursuant to Awards under the Plan is 164,000, subject to the
adjustments provided in Article X, below.  Such shares may be newly-issued
shares, authorized but unissued shares or shares reacquired by the Company on
the open market or otherwise.  Because Performance Stock Units are payable only
in cash, the number of such Performance Stock Units shall not count against the
164,000 maximum described in this paragraph.

   3.2 Availability of Shares for Award.  Shares of Common Stock that are
subject to issuance pursuant to an Award may thereafter be subject to a new
Award:

   (a) if the prior Award to which such shares were subject lapses, expires or
       terminates without the issuance of such shares; or

   (b) shares issued pursuant to an Award are reacquired by the Company
       pursuant to rights reserved by the Company upon the issuance of such
       shares; provided, that shares reacquired by the Company may only be
       subject to new Awards if the Participant received no benefit of
       ownership from the shares.

Shares of Common Stock that are received by the Company in connection with the
exercise of an Award, including the satisfaction of any tax liability or the
satisfaction of a tax withholding obligation, may be made subject to issuance
pursuant to a later Award.

                                ARTICLE IV

16b-3(b)(3) promulgated by the Securities and Exchange Commission pursuant to
the Securities Exchange Act of 1934 (the "Exchange Act").  A majority of the
members of the Committee shall constitute a quorum at any meeting thereof

the members of the entire Committee without notice or meeting.

to be exempt from the application of Code Section 409A.

                                ARTICLE V

                               ELIGIBILITY

                                ARTICLE VI

                                  AWARDS

   6.1 Types of Awards.  Awards under the Plan may be granted in any one or a
combination of the following:

   (a) Stock Options.  An Option shall entitle the Participant to receive
       shares of Common Stock upon exercise of such Option, subject to the
       Participant's satisfaction in full of any conditions, restrictions or
       limitations imposed in accordance with the Plan or the agreement between
       the Company and the Participant governing the award of such Option.  The
       agreement governing the award of an option shall designate whether such
       option is intended to be an incentive stock option or a non-qualified
       stock option, and to the extent that any stock option is not designated
       as an incentive stock option (or even if so designated does not qualify
       as an incentive stock option), it shall constitute a non-qualified stock
       option.  The maximum number of Options that may  be granted to any
       Participant during any fiscal year of the Company is 10,000, subject to
       the adjustments provided in Article X, below.

     (i) Exercise Price.  The exercise price per share of the Common Stock
         purchasable under an Option shall be determined by the Committee. If
         such option is intended to qualify as an incentive stock option, the
         exercise price per share shall not be less than the fair market value
 3
         per share of Common Stock on the date the option is granted (or not
         less than 110% of the such fair market value if the option is granted
         to an individual who owns or is deemed to own stock possessing more
         than 10% of the combined voting power of all classes of stock or the
         Company, a corporation which is the parent of the Company or and
         subsidiary of the Company (each as defined in Section 424 of the Code)
         (a "10% Shareholder")).  For this and all other purposes under the
         Plan, the fair market value shall be the mean between the highest and
         lowest quoted selling prices per share of Common Stock on the New York
         Stock Exchange ("NYSE") or NASDAQ Stock Market ("NASDAQ") (as
         applicable) on the date of grant; provided, that if the Common Stock
         ceases to be listed on either the NYSE or NASDAQ, the Committee shall
         designate an alternative method of determining the fair market value
         of the Common Stock.

     (ii)Option Period.  An Option shall be exercisable at such time and
         subject to such terms and conditions as shall be determined by the
         Committee.  An option that is intended to qualify as an incentive
         stock option shall not be exercisable more than ten years after the
         date it is granted (or five years after the date it is granted, if
         granted to a 10% Shareholder).

   (b) Stock Appreciation Rights.  A Stock Appreciation Right shall entitle the
       Participant to surrender to the Company the Stock Appreciation Right and
       to be paid therefor the amount described in Section 6.1(b)(i)(3) or
       6.1(b)(ii) below, subject to the Participant's satisfaction in full of
       any conditions, restrictions or limitations imposed in accordance with
       the Plan or the agreement between the Company and the Participant
       governing the award of such Stock Appreciation Right. Stock Appreciation
       Rights may be granted in conjunction with all or part of any Stock
       Option under this Plan ("Tandem SAR's"), or may be granted on a
       stand-alone basis ("Stand Alone SAR's").  The maximum number of Stock
       Appreciation Rights that may be granted to any Participant during any
       fiscal year of the Company is 10,000, subject to the adjustments
       provided in Article X, below.

     (i) Tandem SAR's.

       (1) Grant.  Tandem SAR's may be granted in connection with non-qualified
           Stock Options at or after the time that such non-qualified Stock
           Options are granted, but may only be granted in connection with
           incentive Stock Options at the time of grant of such incentive Stock
           Options.

       (2) Term.  A Tandem SAR shall have the same term as the Stock Option to
           which it relates and shall be exercisable only at such time or times
           and to the extent the related Stock Option would be exercisable.

       (3) Exercise.  Upon the exercise of a Tandem SAR, the Participant shall
           be entitled to receive an amount in cash equal in value to the
           excess of the fair market value per share of Common Stock on the
           date of exercise over the Option Price per share of Common Stock as
           specified in the agreement governing the Tandem SAR, multiplied by
           the number of shares in respect to which the Tandem SAR is
           exercised.  The exercise of Tandem SAR's shall require the
           cancellation of a corresponding number of Stock Options to which
           the Tandem SAR's relate, and the exercise of Stock Options shall
           require the cancellation of a corresponding number of Tandem SAR's
           to which the Stock Options relate.

       (4) Expiration or Termination.  A Tandem SAR shall expire or terminate
           at such time as the Stock Option to which it relates expires or
           terminates, unless otherwise provided in the agreement governing the
           grant of the Tandem SAR.

    (ii) Stand Alone SAR's.  A Stand Alone SAR may be granted at such time and
         for such term as the Committee shall determine, and shall be
         exercisable at such time as specified in the agreement governing the
         grant of the Stand Alone SAR.  Upon exercise of a Stand Alone SAR, the
         Participant shall be entitled to receive, in cash, Common Stock, or a
         combination of both (as determined by the Committee), an amount equal
         to the fair market value per share of Common Stock over a value
         specified in the agreement governing the grant of the Stand Alone SAR,
         multiplied by the number of shares in respect to which the Stand Alone
         SAR is exercised.

    (c)	Restricted Stock Awards.  Restricted Stock consists of shares of Common
        Stock that are transferred or sold to the Participant, but which carry
        restrictions such as a prohibition against disposition or an option to
 4
        repurchase in the event of employment termination, and may be subject
        to a substantial risk of forfeiture.  Until such restrictions lapse,
        the Participant may not sell, assign, pledge or otherwise transfer,
        whether voluntarily or involuntarily, the Restricted Stock.  A sale of
        Restricted Stock to a Participant shall be at such price as the
        Committee determines, which price may be substantially below the fair
        market value of the Common Stock at the date of grant.

       (i) Lapse of Restrictions.  The Committee shall establish the conditions
           under which the restrictions applicable to shares of Restricted
           Stock shall lapse. Lapse of the restrictions may be conditioned upon
           continued employment of the Participant for a specified period of
           time, satisfaction of performance goals of the Company or a
           Subsidiary, or any other factors as the Committee deems appropriate.

      (ii) Rights of Holder of Restricted Stock.  Except for the restrictions
           on transfer and/or the Company's option to repurchase the Restricted
           Shares, the Participant shall have, with respect to shares of
           Restricted Stock, all of the rights of a shareholder of Common
           Stock, including, if applicable, the right to vote the shares and
           the right to receive any cash or stock dividends.  Unless otherwise
           determined by the Committee and subject to the terms of the Plan,
           cash or stock dividends on shares of Restricted Stock shall be
           automatically deferred, and shall be paid to the Participant if and
           when the restrictions on the shares of Restricted Stock to which
           such dividends relate lapse.  Cash dividends shall be paid with an
           appropriate rate of interest, as determined by the Committee.

     (iii) Certificates.  The Company may require that the certificates
           evidencing shares of Restricted Stock be held by the Company until
           the restrictions thereon have lapsed.  If and when such restrictions
           lapse, certificates for such shares shall be delivered to the
           Participant.  Such shares may have further restrictions on transfer
           if they have not been registered under the Exchange Act, but shall
           no longer be subject to a substantial risk of forfeiture.

    (d) Performance Stock Awards.  Performance Stock Awards are artificial
         shares that are contingently granted to a Participant, which entitle
         the Participant to actual shares of Common Stock, if predetermined
         objectives are met.  Because the payment of a Performance Stock Award
         is based on a predetermined number of shares of Common Stock, the
         value of the award may increase or decrease depending on the fair
         market value of the Common Stock after the date of grant. The maximum
         number of shares of Performance Stock that may be granted to any
         Participant during any fiscal year of the Company is 10,000, subject
         to the adjustments provided in Article X, below.

       (i) Performance Goals.  The Committee shall establish one or more
           performance goals with respect to each grant of a Performance
           Stock Award. The performance goals may be tailored to meet specific
           objectives.  The performance criteria upon which payment or vesting
           of a Performance Stock Award intended to qualify for the exemption
           under Code Section 162(m) may be based shall be limited to one or
           more of the following, as determined by the Committee:  sales, net
           asset turnover, earnings per share, cash flow, cash flow from
           operations, return on investment in excess of cost of capital (i.e.,
           net operating profit after taxes minus a capital charge), operating
           profit or income, net income, operating income, net income margin,
           return on net assets, return on total sales, return on common
           equity, return on total capital, or total shareholder return.  In
           the case of Performance Stock Awards that are not intended to
           qualify for the exemption under Code Section 162(m), the Committee
           shall designate performance criteria from among the foregoing or
           such other business criteria as it shall determine in its sole
           discretion.  In addition, performance goals may relate to attainment
           of specified objectives by the Participant or by the Company or an
           affiliate, including a division or a department of the Company or
           an affiliate, or upon any other factors or criteria as the Committee
           shall determine.

      (ii) Certification of Satisfaction of Performance Goals.  Following the
           completion of a period for which performance goals have been
           established, the Committee shall certify the extent to which such
           goals have been achieved.

    (e) Performance Stock Unit Awards.  A Performance Stock Unit shall entitle
        the Participant to receive a cash payment equal to the fair market
        value of a share of Common Stock of the Company as of the Vesting Date,
        if predetermined objectives are met.  The "Vesting Date" shall be the
 5
        last day of the performance period for which a performance goal is
        established.  The maximum number of Performance Stock Units that may be
        granted to any Participant during any fiscal year of the Company is
        50,000, subject to the adjustments provided in Article X, below.

       (i) Performance Goals.  The Committee shall establish one or more
           performance goals with respect to each grant of a Performance Stock
           Unit.  The performance goals may be tailored to meet specific
           objectives. The performance criteria upon which payment or vesting
           of a Performance Stock Unit intended to qualify for the exemption
           under Code Section 162(m) may be based shall be limited to one or
           more of the following, as determined by the Committee:  sales, net
           asset turnover, earnings per share, cash flow, cash flow from
           operations, return on investment in excess of cost of capital (i.e.,
           net operating profit after taxes minus a capital charge), operating
           profit or income, net income, operating income, net income margin,
           return on net assets, return on total sales, return on common
           equity, return on total capital, or total shareholder return.  In
           the case of Performance Stock Units that are not intended to qualify
           for the exemption under Code Section 162(m), the Committee shall
           designate performance criteria from among the foregoing or such
           other business criteria as it shall determine in its sole
           discretion.  In addition, performance goals may relate to attainment
           of specified objectives by the Participant or by the Company or an
           affiliate, including a division or a department of the Company or an
           affiliate, or upon any other factors or criteria as the Committee
           shall determine.

      (ii) Certification of Satisfaction of Performance Goals.  Following the
           completion of a period for which performance goals have been
           established, the Committee shall certify the extent to which such
           goals have been achieved.

    (f)  Performance Unit Awards.  Performance Unit Awards entitle the
         participant to cash payments (or, at the election of the Committee,
         their equivalent in shares of Common Stock), if predetermined
         objectives are met.  Because the payment of a Performance Unit Award
         is based on a predetermined cash amount, the value of each unit
         remains constant and does not fluctuate with changes in the market
         value of the Common Stock.  The maximum amount that may be paid to any
         Participant in any fiscal year of the Company pursuant to an award of
         Performance Units shall be $500,000.00

       (i) Performance Goals.  The Committee shall establish one or more
           performance goals with respect to each grant of a Performance Unit
           Award. The performance goals may be tailored to meet specific
           objectives.  The performance criteria upon which payment or vesting
           of a Performance Unit Award intended to qualify for the exemption
           under Code Section 162(m) may be based shall be limited to one or
           more of the following, as determined by the Committee:  sales, net
           asset turnover, earnings per share, cash flow, cash flow from
           operations, return on investment in excess of cost of capital (i.e.,
           net operating profit after taxes minus a capital charge), operating
           profit or income, net income, operating income, net income margin,
           return on net assets, return on total sales, return on common
           equity, return on total capital, or total shareholder return.  In
           the case of Performance Unit Awards that are not intended to qualify
           for the exemption under Code Section 162(m), the Committee shall
           designate performance criteria from among the foregoing or such
           other business criteria as it shall determine in its sole
           discretion.  In addition, performance goals may relate to attainment
           of specified objectives by the participant or by the Company or an
           affiliate, including a division or a department of the Company or an
           affiliate, or upon any other factors or criteria as the Committee
           shall determine.

      (ii) Certification of Satisfaction of Performance Goals.  Following the
           completion of a period for which performance goals have been
           established, the Committee shall certify the extent to which such
           goals have been achieved.

    (g) Annual Long-Term Incentive Awards.  An Annual Long-Term Incentive Award
        entitles a Participant to receive a specified payout in common stock,
        deferred stock, restricted stock or a combination thereof (subject to
        approval of the Committee), if and when certain conditions are
        satisfied.  To elect the payout of a portion of the award in common
        stock, the Participant must inform the Committee in writing prior to
        the start of the fiscal year to which it relates.  The maximum annual
        formula bonus may be fixed at up to 100% of the Participant's base
 6
        salary with the Committee designating the percentage level of
        participation and maximum bonus for each officer of the Company while
        management designates the percentage level of participation and maximum
        bonus for other Participants.

   6.2 Written Agreements.  Each Award granted under the Plan shall be
evidenced by a written agreement, the form of which shall be consistent with
the terms and conditions of the Plan and applicable law, which shall be signed
by an officer of the Company and the Participant.  Until such agreement has
been entered into between the Company and the Participant, the Participant
shall have no rights in any Award approved by the Committee.

   6.3 Application of Code Section 162(m).  Code Section 162(m) prohibits a
publicly-held corporation from taking a deduction for remuneration paid to
certain employees in excess of $1,000,000.  Code Section 162(m)(4)(C) provides
that remuneration payable solely on account of the attainment of one or more
performance goals is not counted toward this limitation, but only if certain
conditions are satisfied.  To the extent that any Award is intended to satisfy
the exception contained in Code Section 162(m)(4)(C), the following shall apply
to such Award:

    (a) Determination of Performance Goals.  The performance goals pursuant to
        which an Award is made must be determined by a committee of the Board
        comprised solely of two or more "outside directors," as that term is
        defined under Code Section 162 and the regulations thereunder (the
        "Outside Directors Committee").  The Committee may serve as the Outside
        Directors Committee if it meets these requirements.  The performance
        goals established by the Outside Directors Committee must be objective,
        and remuneration intended to be excepted under Code Section 162(m)(4)
        (C) must be contingent upon the attainment of the performance goals.

    (b) Approval of Performance Goals.  The material terms under which the
        remuneration is to be paid, including the performance goals, are
        disclosed to shareholders and approved by a majority of the vote in
        a separate shareholder vote before the payment of such remuneration.

    (c) Certification of Satisfaction of Performance Goals.  The Outside
        Directors Committee must certify that the performance goals and any
        other material terms and conditions were in fact satisfied.

    (d) Satisfaction of Code Section 162(m).  In all other respects, the
        requirements of Code Section 162(m)(4)(C) and the regulations
        thereunder must be satisfied.

                                ARTICLE VII

                             PAYMENT FOR AWARDS

   7.1 General.  Payments required, if any, upon a Participant's exercise of an
Award under the Plan may be made in the form of: (i) cash; (ii) Company stock;
(iii) a combination of cash and Company stock; or (iv) such other forms or
means that the Committee shall determine in its discretion and in such manner
as is consistent with the Plan's purpose and the Code, the Exchange Act, or
other applicable laws or regulations.

                                ARTICLE VIII

               EFFECT OF TERMINATION OF EMPLOYMENT ON BENEFITS

   8.1 Termination by Reason of Death.  Unless otherwise provided in an
agreement governing the grant of an Award or as determined by the Committee,
if a Participant incurs termination of employment due to death:

    (a) Any unexpired and unexercised Options and/or Stock Appreciation Rights
        held by such Participant shall thereafter be fully exercisable (whether
        or not such Options or Stock Appreciation Rights were fully vested at
        the time of the Participant's death) by the deceased Participant's
        estate or by a person who acquired the right to exercise the Option or
        Stock Appreciation Right by bequest or inheritance for a period of one
        year immediately following the date of death, or until the expiration
        of the Option or Stock Appreciation Right if shorter.

    (b) Any restrictions on shares of Restricted Stock shall lapse and the
        Participant shall be fully vested in the Restricted Stock.

    (c) The Participant shall receive a prorated payout of any Performance
        Stock Awards, Performance Stock Unit Awards, Performance Unit Awards
        and Annual Long-Term Incentive Awards.  The prorated payout shall be
        determined by the Committee, in its sole discretion, and shall be
 7
        based upon the length of time that the Participant held such Awards
        during the period for which performance is measured and the achievement
        of the established performance goals.

   8.2 Termination by Reason of Disability.  Unless otherwise provided in an
agreement governing the grant of an Award or as determined by the Committee, if
a Participant incurs termination of employment due to disability:

    (a) Any unexpired and unexercised Options and/or Stock Appreciation Rights
        held by such Participant shall thereafter be fully exercisable (whether
        or not such Options or Stock Appreciation Rights were fully vested at
        the time the Participant became disabled) for a period of three years
        (except for incentive stock options, in which case the period shall be
        one year) immediately following the date of such termination of
        employment, or until the expiration of the Option or Stock Appreciation
        Right if shorter.  The Participant's death at any time following such
        termination due to disability shall not affect the foregoing.  In the
        event of termination due to disability, if an incentive stock option is
        exercised more than one year after such termination of employment (or
        such other time period as may apply under Section 422 of the Code),
        such Option shall thereafter be treated as a non-qualified stock
        option.

    (b) Any restrictions on shares of Restricted Stock shall lapse and the
        Participant shall be fully vested in the Restricted Stock.

    (c) The Participant shall receive a prorated payout of any Performance
        Stock Awards, Performance Stock Unit Awards, Performance Unit Awards
        and Annual Long-Term Incentive Awards.  The prorated payout shall be
        determined by the Committee, in its sole discretion, and shall be base
        upon the length of time that the Participant held such Awards during
        the period for which performance is measured and the achievement of the
        established performance goals.

Unless otherwise defined in the agreement governing the grant of an Award,
"disability" shall mean a mental or physical illness or injury that entitles
the Participant to receive benefits under the long term disability plan of the
Company or a Subsidiary, or if the Participant is not covered by such a plan, a
mental or physical illness that renders a Participant totally and permanently
incapable of performing the Participant's duties for the Company or a
Subsidiary.  Notwithstanding the foregoing, a "disability" shall not qualify
under the Plan if it is the result of: (i) a willfully self-inflicted injury or
willfully self-induced sickness; or (ii) an injury or disease contracted,
suffered or incurred, while participating in a criminal offense.  The
determination of disability shall be made by the Committee.  The determination
of disability for purposes of the Plan shall not be construed as an admission
of disability for any other purpose.

   8.3 Voluntary Termination Before Retirement or Termination for Cause.
Unless otherwise provided in an agreement governing the grant of an Award or as
determined by the Committee, if a Participant voluntarily terminates his or her
employment before retirement or is terminated for cause:

    (a) Any unexpired and unexercised Options and/or Stock Appreciation Rights
        held by such Participant shall immediately terminate.  The death or
        disability of the Participant after such a termination of employment
        shall not renew the exercisability of any Option or Stock Appreciation
        Right.

    (b) All shares of Restricted Stock still subject to restriction shall be
        forfeited by the Participant, except the Committee shall have the
        discretion in whole or in part to waive any or all remaining
        restrictions with respect to any or all of such Participant's shares
        of Restricted Stock.

    (c) All Performance Stock Awards, Performance Stock Unit Awards,
        Performance Unit Awards and Annual Long-Term Incentive Awards shall be
        forfeited by the Participant to the Company.

Unless otherwise defined in the agreement governing the grant of an Award,
"termination for cause" shall mean termination because of (i) any act or
failure to act deemed to constitute cause under the Company's established
practices policies or guidelines applicable to the Participant or (b) the
Participant's act or omission constituting gross misconduct with respect to
the Company or a Subsidiary in any material respect.

   8.4 Other Termination.  Unless otherwise provided in an agreement governing
the grant of an Award or as determined by the Committee, if a Participant's
employment terminates for any reason (including retirement) other than the
 8
reasons listed in Section 8.1 through 8.3 above:

    (a) Any unexpired and unexercised Options and/or Stock Appreciation Rights
        held by such Participant shall thereupon terminate, except that any
        such Option or Stock Appreciation Right, to the extent vested on the
        date of the Participant's termination, may be exercised by the
        Participant for a period of three years (except for incentive stock
        options, in which case the period shall be (3) three months)
        immediately following the date of such termination of employment, or
        until the expiration of the Option or Stock Appreciation Right if
        shorter.  The death or disability of the Participant after such a
        termination of employment shall not extend the time permitted to
        exercise an Option or Stock Appreciation Right.

    (b) All shares of Restricted Stock still subject to restriction shall be
        forfeited by the Participant, except the Committee shall have the
        discretion in whole or in part to waive any or all remaining
        restrictions with respect to any or all of such Participant's shares of
        Restricted Stock.

    (c) The Participant shall receive a prorated payout of any Performance
        Stock Awards, Performance Stock Unit Awards, Performance Unit Awards
        and Annual Long-Term Incentive Awards.  The prorated payout shall be
        determined by the Committee, in its sole discretion, and shall be based
        upon the length of time that the Participant held such Awards during
        the period for which performance is measured and the achievement of the
        established performance goals.

Unless otherwise defined in the agreement governing the grant of an Award,
"retirement" shall mean the Participant's termination of employment after
attaining either normal retirement age or the early retirement age as defined
in the principal (as determined by the Committee) tax-qualified plan of the
Company or Subsidiary, and if the Participant is not covered by such a plan,
then age 65, or age 55 with the accrual of 10 years of service.

                                ARTICLE IX

                            NONTRANSFERABILITY

   9.1 General.  Unless otherwise provided in an agreement governing the grant
of an Award, a Participant's rights shall be exercisable during the
Participant's lifetime only by the Participant, and no Award may be sold,
transferred, pledged, assigned or otherwise alienated or hypothecated;
provided, that Options and Stock Appreciation Rights are transferable by will
or pursuant to the laws of descent and distribution.

                                ARTICLE X

                          ADJUSTMENT PROVISIONS

   10.1 Changes in Capitalization.  If the Company shall at any time change the
number of issued shares of Common Stock without new consideration to the
Company (by stock dividends, stock splits, split-up, spin-off, or similar
transactions):

    (a) the total number of shares reserved for issuance under this Plan, the
        number of shares covered by or subject to each outstanding Award, and
        the number of outstanding Performance Stock Units, shall be adjusted so
        that the aggregate consideration payable to the Company, if any, and
        the value of each such Award shall not be changed; and

    (b) the maximum number of Options, Stock Appreciation Rights, Performance
        Stock Units and shares of Performance Stock that may be granted to any
        Participant in any fiscal year of the Company shall be proportionately
        adjusted to reflect the increase or decrease in the issued shared of
        Common Stock.

   10.2 Reorganization, Sale, etc..  Awards granted hereunder may also contain
provisions for their continuation, acceleration, immediate vesting, or for
other equitable adjustments after changes in the Common Stock resulting from
reorganization, sale, merger, consolidation, dissolution, liquidation or
similar circumstances.

   10.3 Substitutions and Assumptions.  If the Company acquires an entity which
has issued and outstanding stock options or other rights, the Company may
substitute stock options or rights for options or rights of such entity,
including options or other rights to acquire stock at less than 100% of the
fair market price of the stock at grant.  The number and kind of such stock
options and other rights shall be determined by the Committee and the total
 9
number of shares reserved for issuance under this Plan shall be appropriately
adjusted consistent with such determination and in such manner as the Committee
may deem equitable to prevent substantial dilution or enlargement of the Awards
granted to, or available for, present or future Participants of this Plan.  The
number of shares reserved for issuance pursuant to Article III may be increased
by the corresponding number of options or other benefits assumed, and, in the
case of a substitution, by the net increase in the number of shares subject to
options or other benefits before and after the substitution.

                                ARTICLE XI

                     AMENDMENT AND TERMINATION OF PLAN

   11.1 General.  The Board, without further approval of the Company's
shareholders, may amend the Plan from time to time or terminate the Plan at any
time, provided that:

    (a) no action authorized by this Article shall reduce the amount of any
        existing Award or change the terms and conditions thereof without the
        Participant's consent; and

    (b) no amendment of the Plan shall, without the approval of the Company's
        shareholders, (i) increase the total number of shares of Common Stock
        that may be issued under the Plan or increase the amount or type of
        Awards that may be granted under the Plan; (ii) change the minimum
        purchase price, if any, of shares of Common Stock that may be made
        subject to Awards under the Plan; (iii) modify the requirements as to
        eligibility for an Award under the Plan; (iv) extend the term of the
        Plan; or (v) constitute a material revision of the Plan under the
        listing standards of the NYSE or NASDAQ, as applicable (or such other
        listing standards then applicable to the Company).

                                ARTICLE XII

                               MISCELLANEOUS

   12.1 Unfunded Status of Plan.  It is intended that the Plan constitute an
"unfunded" plan for incentive and deferred compensation.  The Committee may
authorize the creation of trusts or other arrangements to meet the obligations
created under the Plan to deliver Common Stock or make payments; provides,
however, that unless the Committee otherwise determines, the existence of such
trusts or other arrangements is consistent with the "unfunded" status of the
Plan.


   12.2 Withholding Taxes.  No later than the date as of which an amount first
becomes includible in the gross income of the Participant for federal income
tax purposes with respect to any Award or with respect to any exercise of any
Option or Stock Appreciation Right granted under the Plan, the Participant
shall pay to the Company, or make arrangements satisfactory to the Company or
other entity identified by the Committee regarding the payment of any federal,
state, local or foreign taxes of any kind required by law to be withheld.  Such
withholding obligations may be settled with Common Stock, including Common
Stock that is part of the Award or that is received upon the exercise of the
Award that gives rise to the withholding requirement.  The obligations of the
Company under the Plan shall be conditional upon such payment or arrangements,
and the Company shall, to the extent permitted by law, have the right to deduct
any such taxes from any payment otherwise due to the Participant.  If the
Participant disposes of shares of Common Stock acquired pursuant to an
incentive stock option in any transaction considered to be a disqualifying
transaction under the Code, the Participant must give written notice of such
transfer and the Company shall have the right to deduct any taxes required by
law to be withheld from any amounts otherwise payable to the Participant.

   12.3 No Guaranty of Employment.  Nothing herein shall be construed to
constitute a contract of employment between the Company or Subsidiary and the
Participant.  Except as may be provided in a written contract, the Company or
Subsidiary and each of the Participants continue to have the right to terminate
the employment relationship at any time for any reason.

   12.4 Controlling Law.  The Plan and all Awards made and actions taken
hereunder shall be governed by and construed in accordance with the laws of the
State of Wisconsin (other than its law respecting choice of law).  The Plan
shall be construed to comply with all applicable law and to avoid liability to
the Company or a Subsidiary, including, without limitation, liability under
Section 16(b) of the Exchange Act.

   12.5 Headings.  The headings contained in the Plan are for reference
purposes only, and shall not affect the meaning or interpretation of the Plan.

   12.6 Severability.  If any provision of the Plan shall for any reason be
held to be invalid or unenforceable, such invalidity or unenforceability shall
not affect any other provision hereby, and this Plan shall be construed as if
such invalid or unenforceable provision were omitted.

   12.7 Successors and Assigns.  This Plan shall inure to the benefit of and
be binding upon each successor and assign of the Company.  All obligations
imposed upon a Participant, and all rights granted to the Company hereunder,
shall be binding upon the Participant's heirs, legal representatives and
successors.

   12.8 Entire Agreement.  This Plan and any agreements governing the grant
of Awards hereunder to any Participant constitute the entire agreement with
respect to the subject matter hereof with respect to such Participant, provided
that in the event of any inconsistency between the Plan and any such
agreement(s), the terms and conditions of the Plan shall control.

                 PERFORMANCE STOCK AWARD GRANT AGREEMENT

     THIS PERFORMANCE STOCK AWARD GRANT AGREEMENT (the "Agreement"), by and
between TWIN DISC, INCORPORATED (the "Company") and ___________________________
(the "Employee") is dated this 19th day of January, 2006, to memorialize an
amendment of an award of performance stock of even date herewith.

     WHEREAS, the Company adopted an Stock Incentive Plan in 2004 (the "Plan")
whereby the Compensation Committee of the Board of Directors (the "Committee")
is authorized to grant performance stock awards that entitle an employee of the
Company receiving such award to shares of common stock of the Company if the
Company achieves a predetermined performance objective; and

     WHEREAS, effective January 19, 2006, the Committee made an award of
performance stock to the Employee as an inducement to achieve the below
described performance objective.

     NOW, THEREFORE, in consideration of the premises and of the covenants and
agreements herein set forth, the parties hereto agree as follows:

     1. Performance Stock Award Grant.  Subject to the terms of the Plan, a
copy of which has been provided to the Employee and is incorporated herein by
reference, the Company has granted Employee a performance stock award effective
January 19, 2006.  Such performance stock award shall entitle the Employee to
receive ______ shares of the Company's common stock (the "Shares") if the
Company achieves Two Hundred Fifty Million Dollars ($250,000,000) in
consolidated annual sales revenue in the fiscal year beginning on July 1, 2007
and ending on June 30, 2008 (the "Performance Objective"), subject to the terms
and conditions and restrictions set forth below.

     2. Price Paid by Employee.  The price to be paid by the Employee for the
shares granted shall be  No  Dollars ($ 0.00) per share.

     3. Voluntary Termination of Employment Prior to Retirement/Termination for
Cause.  If prior to attaining the Performance Objective the Employee
voluntarily terminates employment prior to the Employee becoming eligible for
normal or early retirement under the Company's defined benefit pension plan
covering the Employee or the employment of the Employee is terminated for
cause, the performance stock awards granted to such Employee shall be
forfeited.  The Committee shall conclusively determine whether the Employee was
terminated for cause for purposes of this performance stock award.

     4. Death/Disability/Other Termination of Employment Other than Change of
Control of Company.  If prior to attaining the Performance Objective the
Employee dies, becomes permanently disabled, voluntarily terminates employment
after becoming eligible for normal or early retirement under the Company's
defined benefit pension plan covering the Employee, or is terminated for any
reason other than for cause or following a Change in Control of the Company as
described in Section 5 (each a "Qualifying Event"), the performance stock
awards granted to such Employee shall be paid on a prorated basis if and when
the Performance Objective is achieved.  Such prorated performance stock awards
shall be subject to the following terms and conditions:

   (a) The prorated award shall be determined by multiplying the number of
       shares underlying the award by a fraction, the numerator of which is the
       number of days from July 1, 2005, through the Employee's last day of
       employment, and the denominator or which is the number of days from
       July 1, 2005, through June 30, 2008.  Any fractional share of the
       Company resulting from such a prorated award shall be rounded up to a
       whole share of the Company.

   (b) Except as otherwise provided in Section 4(c), shares of the Company
       underlying such prorated awards shall be delivered in the ordinary
       course after the determination by the Committee that the Performance
       Objective has been achieved (and no later than 2-1/2 months after
       June 30, 2008).

   (c) The Committee has the authority in its sole discretion to immediately
       vest the prorated portion of the performance stock awards granted
       hereunder if the Employee experiences a Qualifying Event and deliver
       shares of Company stock underlying such prorated awards as if the
       Performance Objective had been fully achieved.

   (d) The Committee shall conclusively determine whether the Employee shall be
       considered permanently disabled for purposes of this performance stock
       award.

     5. Change of Control.  Notwithstanding Sections 3 and 4 above, if an event
