                                       1


Terms and Conditions

1. Terms and Provisions of Performance Share Award. Pursuant to Section 6 of the
Plan, as of the Award Date the Company has awarded to the Grantee the Base Award
Shares and Premium Award Shares  specified in the Notice.  Such Award is subject
to the following terms and conditions.

2. Award of Base Award Shares  Subject to Service  Requirements.  The Grantee is
hereby awarded the number of Base Award Shares specified in the Notice,  subject
to the following provisions:

      (a) Service for Entire Performance Period. If the Grantee remains employed
      by the Company and/or a Subsidiary  through the Vesting Date stipulated in
      the Notice, then, to the extent not vested or forfeited  previously,  100%
      of the Base Award  Shares  shall vest on the Vesting  Date and the Grantee
      shall be entitled to receive such Shares free of any restrictions.

      (b)  Acceleration of Vesting of Base Award Shares:  If, at the end of each
      calendar year during the Performance  Period, the Company has achieved the
      performance  criteria  established  for that calendar year with respect to
      Base Award Shares,  as  stipulated in Exhibit I of the Notice,  25% of the
      Base Award Shares shall vest and the Grantee  shall be entitled to receive
      such  shares  free of all  restrictions.  The  Committee  shall  determine
      whether the  performance  criteria have been met for any calendar year and
      the number of shares  vesting,  if any,  at its first  regularly-scheduled
      meeting  following the end of such calendar  year,  and any shares vesting
      shall be  transferred  to the Grantee,  free of  restrictions,  as soon as
      administratively practicable thereafter.

      (c) Intervening Qualifying Events. If the Grantee ceases to be employed by
      the Company and/or a Subsidiary prior to the Vesting Date because of death
      or Disability (a  "Qualifying  Event"),  then, as of the date on which the
      Qualifying  Event  occurs,  the  Grantee  shall be entitled to receive all
      unvested  Base Award  Shares.  If the Grantee  retires  later than on year
      after the Award Date (a "Qualifying  Retirement"),  Grantee shall continue
      to vest in the Base  Award  Shares  on the same  basis as if  Grantee  had
      remained an active employee;  provided,  however,  that a forfeiture shall
      occur if the Grantee,  prior to the expiration of the Performance  Period,
      obtains other gainful employment  regardless of whether such employment is
      with a competitor of the Company. The Grantee acknowledges and agrees that
      the  forfeiture of Base Award Shares set forth in the  preceding  sentence
      does not constitute a limitation or restriction on the Grantee's  right to
      obtain other employment,  but is only a restriction on the Grantee's right
      to receive unvested Base Award Shares.

      (d) Other Termination of Employment.  If the Grantee ceases to be employed
      by the  Company  and/or a  Subsidiary  prior to the  Vesting  Date for any
      reason other than a Qualifying  Event of a Qualifying  Retirement then, as
      of the date on which the Grantee's employment  terminates,  all Base Award
      Shares that have not previously  vested under paragraphs (a) and (b) above
      shall immediately be forfeited and returned to the Company.


                                       2


3. Award of Premium Award Share Subject to Performance Criteria. The Grantee has
been awarded the number of Premium Award Shares specified in the Notice, subject
to the following provisions:

      (a) Crediting of Premium Award Shares.  As soon as  practicable  following
      the end of each calendar year during the Performance Period, the Committee
      shall determine if the Company has achieved the  performance  criteria for
      that calendar  year relating to the crediting of Premium Award Shares,  as
      stipulated in Exhibit II of the Notice.  If the performance  criteria have
      been met, then the  percentage  of the Premium Award Shares  stipulated in
      the Notice shall become "credited"  Premium Award Shares.  [If the Company
      has not achieved the performance criteria for that calendar year, then the
      percentage of the Premium  Award Shares  stipulated in the Notice shall be
      forfeited  as of the last day of such  calendar  year.] Any Premium  Award
      Shares  that  have not  become  credited  shares as of the last day of the
      Performance Period shall be forfeited on such day.

      (b) Vesting in Credited  Premium Award  Shares.  The Grantee shall vest in
      the  credited  Premium  Award  Shares on the Vesting Date set forth in the
      Notice,  provided that the Grantee  remains  continuously  employed by the
      company  and/or a Subsidiary  until such date.  At that time,  the Grantee
      shall be  transferred  shares of Company Stock for each  credited  Premium
      Award Share then vesting, free of all restrictions.

      (c) Termination of Employment Prior to Vesting Date. If the Grantee ceases
      to be  employed  by  the  Company  and/or  a  Subsidiary  by  reason  of a
      Qualifying  Event prior to the Vesting  Date,  then any  credited  Premium
      Award Shares as of the date of the  Grantee's  termination  of  employment
      will vest. In the event of a Qualifying Retirement, Grantee shall continue
      to vest in the Premium  Awards  Shares on the same basis as if Grantee had
      remained an active employee,  provided,  however,  that a forfeiture shall
      occur if the Grantee,  prior to the expiration of the Performance  Period,
      obtains other gainful employment  regardless of whether such employment is
      with a competitor of the Company. The Grantee acknowledges and agrees that
      the  forfeiture of Base Award Shares set forth in the  preceding  sentence
      does not constitute a limitation or restriction on the Grantee's  right to
      obtain other employment,  but is only a restriction on the Grantee's right
      to receive unvested Base Award Shares.  The Grantee will forfeit the right
      to any  uncredited  Premium  Award  Shares  that  have not been  forfeited
      previously.  If the  Grantee's  employment  with the  Company  and/or  its
      Subsidiaries  terminates for any reason other than a Qualifying Event or a
      Qualifying  Retirement  prior  to  the  Vesting  Date,  all  credited  and
      uncredited  Premium Award Shares will be forfeited and said shares will be
      returned to the Company.

4. Confidential Information; Noncompetition; Nonsolicitation.

      (a)  Grantee  acknowledges  that all secret or  confidential  information,
      knowledge or data relating to the Company or any of its  Subsidiaries  and
      their   respective   businesses  that  Grantee  obtains  during  Grantee's
      employment  by the  Company  or any of its  Subsidiaries  and  that is not
      public  knowledge  (other than as a result of the Grantee's  violations of
      this Section 4(a))  ("Confidential  Information")  is highly sensitive and
      proprietary and includes, without limitation:  product design information,
      manufacturing processes and methods,


                                       3


      information  regarding  new  product  development,  information  regarding
      strategic or tactical planning,  information  regarding pending or planned
      competitive bids, and information  regarding key employees.  Grantee shall
      not communicate,  divulge or disseminate  Confidential  Information at any
      time during or after Grantee's  employment  with the Company,  except with
      the prior written  consent of the Company or as otherwise  required by law
      or legal process. All computer software,  telephone lists, customer lists,
      price  lists,  contract  forms,  catalogs,  records,  files  and  know-how
      acquired  while an  employee  of the  Company  are  acknowledge  to be the
      property  of the  Company and shall not be  duplicated,  removed  from the
      Company's  possession  or premises or made use of other than in pursuit of
      the Company's business or as may otherwise be required by law or any legal
      process, and, upon termination of employment for any reason, Grantee shall
      deliver to the Company,  without  further  demand,  all such items and any
      copies thereof which are then in his or her possession or under his or her
      control.

      (b)  For  a  one  year  period  beginning  on  Grantee's   termination  of
      employment,  Grantee will not, except upon prior written permission signed
      by an  authorized  officer  of the  Company,  consult  with or advise  or,
      directly or indirectly,  as owner, partner, officer or employee, engage in
      business  with any  company in  competition  with the  Company or with any
      corporation or entity  controlled by,  controlling or under common control
      with any such company.  Not withstanding  the foregoing,  Grantee may make
      and retain investments in not more than three percent of the equity of any
      such company if such equity is listed on a national securities exchange or
      regularly traded in an over-the-counter market.

      (c)  For  a  one  year  period  beginning  on  Grantee's   termination  of
      employment,   Grantee  will  not,  directly  or  indirectly,  solicit  for
      employment or employ on behalf of any organization  other than the Company
      or one of its Subsidiaries or employ any person employed by the Company or
      any of its Subsidiaries, nor will Grantee, directly or indirectly, solicit
      for employment on behalf of any organization other than the Company or one
      of its Subsidiaries or be involved in any way in the hiring process of any
      person known by Grantee (after  reasonable  inquiry) to be employed at the
      time by the Company or any of its Subsidiaries.

      (d) In the event of a breach of Grantee's  covenants under this Section 4,
      all  Performance  Stock Awards shall  immediately  be forfeited as of such
      breach and it is understood  and agreed that the Company shall be entitled
      to  injunctive  relief as well as any other legal or  equitable  remedies.
      Grantee  acknowledges  and  agrees  that the  covenants,  obligations  and
      agreements of the Grantee in this Section 4 relate to special,  unique and
      extraordinary  matters  and that a  violation  of any of the terms of such
      covenants,  obligations or agreements  will cause the Company  irreparable
      injury for which  adequate  remedies are not available at law.  Therefore,
      Employee  agrees  that the Company  shall be  entitled  to an  injunction,
      restraining  order or such other equitable relief (without the requirement
      to post bond) as a court of competent  jurisdiction  may deem necessary or
      appropriate  to restrain  Grantee from  committing  any  violation of such
      covenants,  obligations  or  agreements.  These  injunctive  remedies  are
      cumulative  and in  addition  to any other  rights and  remedies  that the
      Company may have. The Company and Grantee hereby irrevocably submit to the
      exclusive  jurisdiction  of the courts of Wisconsin and the Federal courts
      of the United  States

      involving Confidential Information,  trade secrets or the violation of the
      provisions of this Section 4.

nominee[s] as his/her irrevocable proxy to vote, in the nominee[s]'  discretion,
all shares of Company Stock  transferred  to the Grantee under this Agreement at
the  annual  meeting  of  shareholders  and  at  any  other  meetings  at  which
shareholders are entitled to vote. The Company will provide appropriate means to

reasonable  time as specified  by the Company,  this Award shall become null and
void.  Except as  otherwise  provided in this  Agreement,  the terms of the Plan
shall  control  as to  voting,  dividends  and other  rights,  restrictions  and
limitations.

6. Tax  Consequences.  The  Grantee  understands  that the award of  Performance

represents  that he or she has been  advised to consult a tax advisor  regarding
the implications of this Agreement.  The Grantee further acknowledges that he or
she is not relying on the Company for any tax, financial or legal advice; and it

accordance  with the Plan.  The  resolution  of such a dispute by the  Committee
shall be final and binding on the Company and Grantee.

8. Fractional Shares. If any calculation of Company Stock to be awarded or to be
forfeited or to be released from  restrictions or limitations  would result in a
fractional share, such fractional share shall be paid in cash.

9. Rights as a Stockholder.  Subject to Section 5, the Grantee shall have all of
the rights of a stockholder  with respect to the Performance  Shares,  including
the right to vote on all matters with respect to which the  stockholders  of the
Company have the right to vote and the right to receive dividends  thereon.  Any
dividends  paid on shares of Company Stock  subject to forfeiture  shall also be
subject to  forfeiture  until such date as the  underlying  shares to which they
relate become vested, and shall be paid in cash upon vesting.

10.  Restrictions  on Transfer.  The  Performance  Shares awarded to the Grantee
under this  Agreement  may not be  transferred  or otherwise  disposed of by the
Grantee, including by way of sale, assignment,  transfer, pledge,  hypothecation
or otherwise,  except as permitted by the  Committee,  or by will or the laws of
descent  and   distribution.   Any   purported   sale,   assignment,   mortgage,
hypothecation, transfer, pledge, encumbrance, gift, transfer in trust (voting or
other) or other  disposition  of, or creation of a security  interest in or lien
on, any of the  Performance  Shares by any holder  thereof in  violation  of the
provisions of this Agreement shall be invalid, and the Company will not transfer
any of said shares on its books nor will any of said shares be entitled to vote,
nor will any  dividends  be paid  thereon,  unless and until there has been full
compliance  with


                                       5


said provisions to the satisfaction of the Company.  The foregoing  restrictions
are in addition to and not in lieu of any other  remedies,  legal or  equitable,
available to enforce said provisions.

11.  Approvals.  No shares of Company Stock shall be issued under this Agreement
unless  and until all legal  requirements  applicable  to the  issuance  of such
shares  have  been  complied  with to the  satisfaction  of the  Committee.  The
Committee  shall  have the  right to  condition  any  issuance  of shares to the
Grantee on the Grantee's undertaking in writing to comply with such restrictions
on the  subsequent  disposition  of such  shares  as the  Committee  shall  deem
necessary or advisable as a result of any applicable law or regulation.

12.  Change in  Control.  In the event of a change in  control,  all Base  Award
Shares  that  have not yet  vested or been  previously  forfeited  shall  become
immediately vested and all restrictions and forfeiture  conditions applicable to
such shares shall  immediately  lapse.  Premium  Award Shares do not vest upon a
