         WHEREAS, Employee is currently employed as the President and Chief
Executive Officer of Employer; and

         WHEREAS, the Employer and the Employee have previously entered into an
employment agreement dated July 1, 2002 (the "Prior Agreement"); and

         WHEREAS, the Employer and the Employee desire to amend the provisions

Employee agrees that he will not compete with the Employer and to make other
miscellaneous modifications; and

         WHEREAS, Employee is willing to commit himself to serve Employer upon
the terms and conditions herein provided; and

         WHEREAS, Employer and Employee have agreed to restrict Employee's
ability to disclose confidential information and to compete with Employer with
respect to the type of business conducted by Employer and its subsidiaries
(collectively, the "Company"); and

         WHEREAS, any breach of this Agreement by Employee will cause
irreparable injury to Employer; and

         WHEREAS, Employee has consulted with and obtained advice from
independent legal counsel concerning the terms and conditions of this Agreement,
or has had the opportunity to do so which he has declined; and

         WHEREAS, in order to effect the foregoing, Employer and Employee wish
to enter into this Agreement on the terms and conditions set forth below.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements hereinafter set forth, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, it
is hereby mutually agreed as follows:

deemed to be an integral part of this Agreement.

leaves of absence, to devote all of his working time, attention and energy,
using his best efforts, to the duties and
<PAGE>
responsibilities as are customary for an employee of a business of like size and
nature to that of the Employer, as well as to any other duties and
responsibilities that may be mutually agreed upon in writing between Employer
and Employee from time to time; provided, however, that Employee shall be
permitted to serve as a director of other noncompeting entities and/or as a
director and/or officer of a nonprofit or industry association so long as such
activities do not interfere with the performance of Employee's duties hereunder;

                  (b) faithfully to serve and further the interests of Employer
in every lawful way, giving honest, diligent, loyal and cooperative service to
Employer;

time, may be reasonably and uniformly adopted by Employer, including, without
limitation, those rules and policies regarding disclosure of information
concerning Employer, its business, affairs, plans or customers; and

to, acting as President and Chief Executive Officer, as well as any of the other
operations requiring Employee's assistance.

         During the Term it shall not be a violation of this Agreement for
Employee to manage personal investments, so long as such activities do not
significantly interfere with the performance of Employee's responsibilities as
an employee of Employer in accordance with this Agreement.

         3. Compensation. As compensation for the services to be performed by
Employee under this Agreement, and the noncompetition covenant contained herein,
Employer agrees to pay to Employee, and Employee agrees to accept, an initial

intervals, subject to required payroll withholding provisions. Employee shall be
eligible for changes in future years consistent with performance and Employer's
evaluation criteria and compensation policies.

determined by the Compensation and Leadership Development Committee of Employer,
but in a manner not less favorable than other executive officers of Employer.

         5. Employee Benefits. Employee shall receive benefits that are
substantially similar to those offered under Employer's benefit plans and
programs for an executive officer, including, without limitation, any medical,
life, disability, and vacation.

                           (iii) The capitalized terms used in this Section
12(b) shall have the meanings as follows:

                                    (A) Business. "Business" shall mean the
                  business and operations of the Company.


                                    (B) Competitive Services. "Competitive
                  Services" shall mean a service or product, developed,
                  marketed, distributed or provided by a Competitor, which is
                  the same as or is directly competitive with a service or
                  product constituting a part of the Business and with respect
                  to which the Employee has acquired confidential information by
                  reason of the Employee's position and duties with the Company.

                                    (C) Competitor. "Competitor" shall mean (a)
                  any person engaged in, or about to become engaged in, the
                  development, marketing, distribution or provision of any
                  Competitive Service on behalf of other parties, and (b) any
                  customer of the Company, as of the date of this Agreement or
                  during the Term, which begins to perform for itself services
                  previously provided by the Company.

                                    (D) Restricted Area. "Restricted Area" shall
                  mean, collectively: (a) Outagamie, Winnebago and Brown

                  Term, a place of business at or through which it engaged in
                  the Business.

                           (iv) Nothing in Section 12(b) shall prohibit the
Employee from owning or acquiring securities of any corporation or other
business enterprise that may be engaged in activities described in this Section,
provided that: (A) the Employee is not an officer, director or employee of, or
consultant to, such corporation or business enterprise; (B) such securities are
held by the Employee for investment purposes only and represent less than five
percent (5%) of the total voting power and of the total equity interests of such

                           (v) It shall not be deemed a violation of this
Section 12(b) if the Employee accepts employment with a business entity which is
diversified and made up of separate divisions in which, as to parts of its
business, is not a Competitor, provided that Employer shall be furnished prior
to such employment definitive written assurances satisfactory to it, separately
from the Employee and such business entity, that the Employee will not be
expected, required or permitted to, and in fact does not, render services
directly or indirectly to a division or a part of such business entity which
division or part is a Competitor.

                  (c) The parties agree that the profitability and reputation of
Employer also depend on employment relationships with its employees. Employee
agrees that he will not cause, request, or advise any employees of Employer
during the Term to terminate or curtail their employment with the Company during
the Term (except for performance related terminations in accordance with
Employer standards, in consultation with Employer's Human Resources Department)
and for two years after the Term.

                  (d) During the Term, Employee shall not be an officer or
employee of any other business entity without Employer's prior written consent,
except as otherwise permitted herein.

         13. Confidentiality. Employee recognizes that as a key member of the
staff of Employer, Employee occupies a position of trust with respect to
business information of a secret or confidential nature, which is the property
of the Company, and which was imparted to or developed by Employee from time to
time in the course of Employee's duties. Employee, therefore, agrees that:

                  (a) Employee will not at any time or in any manner, directly
or indirectly, use or disclose such information, except as specifically directed
to do so by Employer or a court of competent jurisdiction;

                  (b) immediately upon termination of employment with Employer,
he will promptly return to Employer, at its direction and expense, any and all
copies of records, drawings, writings, materials, memoranda, computer programs
and printouts and other data pertaining to such secret or confidential
information; provided, however, that Employee shall be permitted to retain his
personal property; and

                  (c) information of a secret or confidential nature is any
information that would constitute a "trade secret," including but not limited
to, test programs and systems relating to inventory control or any other aspect
of the business of the Company; patents and patent applications; copyrights or
copyright applications, inventions and improvements, whether patentable or not;
writings, whether copyrightable or not; development projects; machines,
policies, processes, formulas, techniques, normative data, know-how, data, data
bases, computer design, computer programs or software and facts relating to
development and implementation of inventory controls relative to the business of
the Company, requirements for systems and programs, customer lists, customers'
purchases or rentals, business records, price lists, business plans and
forecasts and other trade secrets.

                  (d) Provided, however, that subparagraphs (a) and (c) above
shall not apply to any such information which (1) was or is in the public domain
or (2) hereafter through an act or failure becomes information generally
available to the public.

                  (e) In addition, the terms of the Employer's Agreement with
Regard to Proprietary Information Including Inventions, Patents, Copyrights,
Trade Secrets, and Confidential Information, dated as of June 1, 1990 between
Employer and Employee (the "Trade Secrets Agreement") shall remain in full force
and effect.

         14. Remedies. In addition to other remedies provided by law or equity,
upon a breach by Employee of any of the covenants contained in Sections 12 and
13 hereof, Employer shall be entitled to seek an injunction against Employee
prohibiting any further breach of the covenants contained herein. The parties
agree that it is impossible to measure in money the damages that may accrue to
the Company by reason of Employee's failure to perform any of his obligations
under this Agreement. Therefore, in the event of any controversy concerning
rights or obligations under this Agreement, such rights or obligations may be
enforceable in a court of competent jurisdiction at law or equity by a decree of
specific performance or, if the Company elects, by obtaining damages or such
other relief as the Company may elect to pursue. Such remedies, however, shall
be cumulative and nonexclusive and shall be in addition to any other remedies
which the Company may have.

         15. Assignment. The rights, duties and obligations hereunder may not be
assigned or delegated by either party without the other's written consent.

         16. Notice. Any notice (including notice of change of address)
permitted or required to be given pursuant to the provisions of this Agreement
shall be made as provided in the Purchase Agreement.

         17. Waiver. The failure to enforce any provision of this Agreement by
either party shall not operate or be construed as a waiver of any provision or
obligation of either party.

         18. Invalidity of Any Provision. The provisions of this Agreement are
severable, it being the intention of the parties hereto that should any
provisions hereof be invalid or unenforceable, such invalidity or
unenforceability of any provision shall not affect the remaining provisions
hereof, but the same shall remain in full force and effect as if such invalid or
unenforceable provisions were omitted.

         19. Applicable Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of Wisconsin.

         20. Headings. Headings in this Agreement are for informational purposes
only and shall not be used to construe the intent of this Agreement.

         21. Counterparts. This Agreement may be executed simultaneously in any
number of counterparts, each of which shall be deemed an original but all of
which together shall constitute one and the same agreement.



                                       7

         22. Reasonableness of Restrictions. EMPLOYEE HAS HAD THE OPPORTUNITY TO
CONSULT COUNSEL, HAS READ THIS AGREEMENT AND AGREES THAT THE CONSIDERATION
PROVIDED BY EMPLOYER IS FAIR AND REASONABLE AND FURTHER AGREES THAT THE
POST-EMPLOYMENT RESTRICTIONS ON EMPLOYEE'S ACTIVITIES ARE LIKEWISE FAIR AND
REASONABLE.

         23. Amendment. This Agreement may be further amended or canceled by
mutual agreement of the parties in writing without the consent of any other
person and, so long as Employee lives, no person, other than the parties hereto,
shall have any rights under or interest in this Agreement or the subject matter
hereof.

         24. Entire Agreement. This Agreement, together with the Change in
Control Agreement and the Trade Secrets Agreement and the other documents and
materials referred to herein or therein (collectively, the "Effective
Agreements"), constitute the entire understanding of the parties with respect to
the subject matter hereof. There are no restrictions, promises, warranties,
covenants or undertakings other than those expressly set forth herein and
therein. The Effective Agreements supersede all prior negotiations, agreements
and undertakings between the parties with respect to such subject matter,
including without limitation the Prior Agreement.

         IN WITNESS WHEREOF, the parties hereto have executed this Employment
Agreement as of the date first above written.
