           ------

           tenure, salary, age, health and other qualifications make him
           eligible to participate. The Company does not guarantee the adoption
           or continuance of any particular employee benefit plan or program
           during the term of this Agreement, and Executive's participation in

           normal policies for expense verification.

5.   Confidential Information. Except as permitted or directed by the Company's
     ------------------------
     Board of Directors, during the term of this Agreement and for a period of
     five years thereafter, Executive shall not divulge, furnish or make
     accessible to anyone or use in any way (other than in the ordinary course
     of the business of the Company) any confidential or secret knowledge or
     information of the Company which Executive has acquired or become
     acquainted with or will acquire or become acquainted with prior to the
     termination of the period of his employment by the Company (including
     employment by the Company or any affiliated companies prior to the date of
     this Agreement), whether developed by himself or by others, concerning any
     trade secrets, confidential or secret designs, processes, formulae, plans,
     devices or material (whether or not patented or patentable) directly or
     indirectly useful in any aspect of the business of the Company, any
     customer or supplier lists of the Company, any confidential or secret
     development or research work of the Company, or any other confidential
     information or secret aspects of the business of the Company. Executive
     acknowledges that the above-described knowledge or information constitutes
     a unique and valuable asset of the Company and represents a substantial
     investment of time and expense by the Company and its predecessors, and
     that any disclosure or other use of such knowledge or information other
     than for the sole benefit of the Company would be wrongful and would cause
     irreparable harm to the Company. Both during and after the term of this
     Agreement, Executive will refrain from any acts or omissions that would
     reduce the value of such knowledge or information to the Company. The
     foregoing obligations of confidentiality, however, shall not apply to any
     knowledge or information which is now published or which subsequently
     becomes generally publicly known in the form in

<PAGE>

     which it was obtained from the Company, other than as a direct or indirect
     result of the breach of this Agreement by Executive.

     --------
     Executive will be engaged in or associated with the planning and
     implementing of projects, programs and ventures involving the Company and
     third parties, and Executive hereby expressly acknowledges and agrees that
     all rights in such projects, programs and ventures shall belong to the
     Company. Except as formally approved by the Company's Board of Directors,
     Executive shall not be entitled to any interest in such projects, programs
     and ventures or to any commission, finder's fee or other compensation in
     connection therewith, other than the salary and compensation to be paid to
     Executive as provided in this Agreement, described in Section 4.01 of this

        Executive, either directly or indirectly; and, in particular, Executive
        agrees that he will not, directly or indirectly, induce any employee of
        the Company to carry out, directly or indirectly, any such activity.

8. Patent and Related Matters.
   ---------------------------

   8.01 Disclosure and Assignment.  Executive will promptly disclose in writing
        -------------------------
        to the Company complete information concerning each and every invention,
        discovery, improvement, device, design, apparatus, practice, process,
        method or product, whether patentable or not, made, developed,
        perfected, devised, conceived or first reduced to practice by Executive,
        either solely or in collaboration with others, during the term of this
        Agreement, or within six months thereafter, whether or not during
        regular working hours, relating either directly or indirectly to the
        business, products, practices, or techniques of the Company (hereinafter
        referred to as "Developments"). Executive, to the extent that he has the
        legal right to do so, hereby acknowledges that any and all of said
        Developments are the property of the Company and hereby assigns and
        agrees to assign to the Company any and all of Executive's right, title
        and interest in and to any and all of such Developments. Without
        limiting the foregoing, any and all original works of authorship which
        are created by Executive (solely or jointly with others) within the
        scope of Executive's employment and which are protectable by copyright
        law shall be deemed "works made for hire," as that term is defined in
        the U.S. Copyright Act (17 U.S.C. Section 101).

  8.02  Future Developments.  As to any future Developments made by Executive
        -------------------
        that relate to the business, products or practices of the Company and
        that are first conceived or reduced to practice during the term of this
        Agreement, or within six months thereafter, but that are claimed for any
        reason to belong to an entity or person other than the Company,
        Executive will promptly disclose the same in writing to the Company and
        shall not disclose the same to others if the
<PAGE>

        Company, within twenty (20) days thereafter, shall claim ownership of
        such Developments under the terms of this Agreement. If the Company
        makes such claim, Executive agrees that, insofar as the rights (if any)
        of Executive are involved, it will be settled by arbitration in
        accordance with the rules of the American Arbitration Association. The
        locale of the arbitration shall be Minneapolis, Minnesota (or other
        locale convenient to the Company's principal executive offices). If the
        Company makes no such claim, Executive hereby acknowledges that the
        Company has made no promise to receive and hold in confidence any such
        information disclosed by Executive.

  8.03  Limitation on Sections 8.01 and 8.02.  The provisions of Sections 8.01
        ------------------------------------
        and 8.02 shall not apply to any Development meeting the following
        conditions:

        (a) such Development was developed entirely on Executive's own time;

        (b) such Development was made without the use of any Company equipment,
            supplies, facility or trade secret information;

        (c) such Development does not relate:

            (i)  directly to the business of the Company; or
            (ii) to the Company's actual or demonstrable anticipated research;

        (d) such Development does not result from any work performed by
            Executive for the Company.

  8.04  Assistance of Executive.  Upon request and without further compensation
        -----------------------
        therefor, but at no expense to Executive, and whether during the term of
        this Agreement or thereafter, Executive will do all lawful acts,
        including, but not limited to, the execution of papers and lawful oaths
        and the giving of testimony, that in the opinion of the Company, its
        successors and assigns may be necessary or desirable in obtaining,
        sustaining, reissuing, extending and enforcing United States and foreign
        Letters Patent, including, but not limited to, design patents, on any
        and all of such Developments, and for perfecting, affirming and
        recording the Company's complete ownership and title thereto, and to
        cooperate otherwise in all proceedings and matters relating thereto.

  8.05  Records.  Executive will keep complete, accurate and authentic accounts,
        -------
        notes, data and records of all Developments in the manner and form
        requested by the Company. Such accounts, notes, data and records shall
        be the property of the Company, and, upon its request, Executive will
        promptly surrender the same to it or, if not previously surrendered upon
        its request or otherwise, Executive will surrender the same, and all
        copies thereof, to the Company upon the conclusion of his employment.
<PAGE>

  8.06  Obligations, Restrictions and Limitations.  Executive understands that
        -----------------------------------------
        the Company may enter into agreements or arrangements with agencies of
        the United States Government, and that the Company may be subject to
        laws and regulations which impose obligations, restrictions and
        limitations on it with respect to inventions and patents that may be
        acquired by it or that may be conceived or developed by employees,
        consultants or other agents rendering services to it. Executive agrees
        that he shall be bound by all such obligations, restrictions and
        limitations applicable to any such invention conceived or developed by
        him during the term of this Agreement and shall take any and all further
        action that may be required to discharge such obligations and to comply
        with such restrictions and limitations.

9. Termination.
   ------------

  9.01  Grounds for Termination.  This Agreement shall terminate prior to the
        -----------------------
        expiration of the initial term set forth in Section 2 or any extension

        extension thereof:

        (b)  the Board of Directors of the Company shall determine that:

             (i)   Executive has become disabled;

             (ii)  Executive had breached this Agreement in any material
                   respect, which breach is not cured by Executive or is not
                   capable of being cured by Executive within thirty (30) days
                   after written notice of such breach is delivered to
                   Executive; or

             (iii) Executive has engaged in willful and material misconduct,
                   including willful and material failure to perform his duties
                   as an officer or employee of the Company.

Notwithstanding any termination of this Agreement, Executive, in consideration
of his employment hereunder to the date of such termination, shall remain bound
by the provisions of this Agreement that specifically relate to periods,
activities or obligations upon or subsequent to the termination of Executive's
employment.

  9.02  "Disability" Defined. The Board of Directors may determine that
        --------------------
        Executive has become disabled, for the purpose of this Agreement, in the
        event that Executive shall fail, because of illness or incapacity, to
        render services of the character contemplated by this Agreement over a
        period of ninety (90) days during any one hundred and eighty (180) day
        period. The existence or nonexistence of grounds for termination because
        of disability shall be made in good faith by the Board of Directors
        after notice in writing given to Executive at least thirty (30) days
        prior to such determination. During such thirty (30) day period,
        Executive

         records, manuals, books, blank forms, documents, letters, memoranda,
         notes, notebooks, reports, data, tables, calculations or copies
         thereof, which are the property of the Company or which relate in any
         way to the business, products, practices or techniques of the Company,
         and all other property, trade secrets and confidential information of
         the Company, including, but not limited to, all documents which in
         whole or in part contain any trade secrets or confidential information
         of the Company, which in any of these cases are in his possession or
         under his control.

10. Miscellaneous.
    --------------

    10.01  Governing Law.  This Agreement is made under and shall be governed by
           -------------
           and construed in accordance with the laws of the State of Minnesota.

    10.02  Prior Agreements. This Agreement contains the entire Agreement of the
           ----------------
           parties relating to the subject matter hereof and supersedes all
           prior Agreements and understandings with respect to such subject
           matter, and the parties hereto have made no Agreements,
           representations or warranties relating to the subject matter of this
           Agreement which are not set forth herein.

    10.03  Withholding Taxes. The Company may withhold from any benefits payable
           -----------------
           under this Agreement all federal, state, city or other taxes as shall
           be required pursuant to any law or governmental regulation or ruling.

    10.04  Amendments.  No amendment or modification of this Agreement shall be
           ----------
           deemed effective unless made in writing and signed by the parties
           hereto.

    10.05  No Waiver. No term or condition of this Agreement shall be deemed to
           ---------
           have been waived, nor shall there be any estoppel to enforce any
           provisions of this Agreement, except by a statement in writing signed
           by the party against whom enforcement of the waiver or estoppel is
           sought. Any written waiver shall not be deemed a continuing waiver
           unless specifically stated, shall operate only as to the specific
           term or condition waived and shall not constitute a waiver of such
           term or condition for the future or as to any act other than that
           specifically waived.

    10.06  Severability.  To the extent any provision of this Agreement shall be
           ------------
           invalid or unenforceable, it shall be considered deleted here from
           and the remainder of such provision and of this Agreement shall be
           unaffected and shall continue in full force and effect. In
           furtherance and not in limitation of the foregoing, should the
           duration or geographical extent of, or business activities covered
           by,
<PAGE>

           any provision of this Agreement be in excess of that which is
           valid and enforceable under applicable law, then such provision shall
           be construed to cover only that duration, extent or activities which
           may validly and enforceably be covered. Executive acknowledges the
           uncertainty of the law in this respect and expressly stipulates that
           this Agreement be given the construction which renders its provisions
           valid and enforceable to the maximum extent (not exceeding its
           express terms) possible under applicable law.

   10.07   Assignment.  This Agreement shall not be assignable, in whole or in
           ----------
           part, by either party without the written consent of the other party,
           except that the Company may, without the consent of Executive, assign
           its rights and obligations under this Agreement to any corporation,
           firm or other business entity with or into which the Company may
           merge or consolidate, or to which the Company may sell or transfer
           all or substantially all of its assets, or of which 50% or more of
           the equity investment and of the voting control is owned, directly or
           indirectly, by, or is under common ownership with, the Company. After
           any such assignment by the Company, the Company shall be discharged
           from all further liability hereunder and such assignee shall
           thereafter be deemed to be the Company for the purposes of all
           provisions of this Agreement including this Section 10.

  10.08    Injunctive Relief.  Executive agrees that it would be difficult to
           -----------------
           compensate the Company fully for damages for any violation of the
           provisions of this Agreement, including without limitation the
           provisions of Sections 5, 7, 8 and 9.03. Accordingly, Executive
           specifically agrees that the Company shall be entitled to temporary
           and permanent injunctive relief to enforce the provisions of this
           Agreement and that such relief may be granted without the necessity
           of proving actual damages. This provision with respect to injunctive
           relief shall not, however, diminish the right of the Company to claim
           and recover damages in addition to injunctive relief.

IN WITNESS WHEREOF, Executive and the Company have executed this Agreement as of
the date set forth in the first paragraph.
