the legitimate interests of the Company.

      (f) Blue Pencil Doctrine. If the duration or geographical extent of, or
business activities covered by, this Section 7 are in excess of what is valid
and enforceable under applicable law, then such provision shall be construed to
cover only that duration, geographical extent or activities that are valid and
enforceable.

      8. Patent and Related Matters.

      (a) Disclosure and Assignment. The Employee will 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 the Employee, either solely or in collaboration
with others, during the term of this Agreement relating either directly to the
business, products, practices or techniques of the Company ("Developments"). The
Employee, to the extent that he has the legal right to do so, hereby
acknowledges that any and all of the Developments are the property of the
Company and hereby assigns and agrees to assign to the Company any and all of
the Employee's right, title and interest in and to any and all of the
Developments. At the request of the Company, the Employee will confer with the
Company and its representatives for the purpose of disclosing all Developments
to the Company as the Company shall reasonably request during the period of the
Employee's employment with the Company.

      (b) Limitation on Sections 8. The provisions of Section 8 shall not apply
to any Development meeting the following conditions:

            (i) such Development was developed entirely on the Employee's own
      time;

            (ii) such Development does not relate (A) directly to the business
      of the Company or (B) to the Company's actual or demonstrably anticipated
      research or development.

      (c) Assistance of the Employee. Upon request and without further
compensation therefore, but at no expense to the Employee, the Employee 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,
may be necessary or desirable in obtaining, sustaining, reissuing, extending and
enforcing United States and foreign copyrights and Letters Patent, including but
not limited to, design patents, on the 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.

      (d) Records. The Employee will keep complete, accurate and authentic
accounts, notes, data and records of the 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, the Employee will promptly
surrender same to it or, if not previously surrendered upon its request or
otherwise, the Employee will surrender the same, and all copies (both electronic
and hard copies) thereof, to the Company upon the conclusion of his employment.

      (e) Obligations, Restrictions and Limitations. The Employee 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 which may be acquired by it or which may be
conceived or developed by employees, consultants or other agents rendering
services to it. The Employee shall be bound by all such obligations,
restrictions and limitations applicable to any such invention conceived or
developed by him while he is employed by the Company and shall take any and all
further action which may be required to discharge such obligations and to comply
with such restrictions and limitations.

                                      -4-

      (f) Copyrightable Material. All right, title and interest in copyrightable
material that the Employee shall conceive or originate, either individually or
jointly with others, and which arise out of the performance of this Agreement,
will be the property of the Company and are by this Agreement assigned to the
Company along with ownership of any and all copyrights in the copyrightable
material. Upon request and without further compensation therefore, but at no
expense to the Employee, the Employee shall execute all papers and perform all
other acts necessary to assist the Company to obtain and register copyrights on
such materials in any and all countries. Where applicable, works of authorship
created by the Employee for the Company in performing his responsibilities under
this Agreement shall be considered "works made for hire," as defined in the U.S.
Copyright Act.

      (g) Know-How and Trade Secrets. All know-how and trade secret information
conceived or originated by the Employee that arises out of the performance of
his obligations or responsibilities under this Agreement or any related material
or information shall be the property of the Company, and all rights therein are
by this Agreement assigned to the Company.

      9. Termination of Employment.

      (a) Grounds for Termination. The Employee's employment shall terminate
prior to the expiration of the initial term set forth in Section 2 or any
extension thereof in the event that at any time:

            (i) The Employee dies,

            (ii) The Employee becomes "disabled," so that he cannot perform the
      essential functions of his position with reasonable accommodation,

            (iii) The Board of Directors of the Company elects to terminate this
      Agreement for "cause" and notifies the Employee in writing of such
      election,

            (iv) The Board of Directors of the Company elects to terminate this
      Agreement without "cause" and notifies the Employee in writing of such
      election, or

            (v) The Employee elects to terminate this Agreement with "good
      reason" and notifies the Company in writing of such election.

            (vi) The Employee elects to terminate this Agreement without "good
      reason" and notifies the Company in writing of such election.

      If this Agreement is terminated pursuant to clause (i), (ii) or (iii) of
this Section 9(a), such termination shall be effective immediately. If this
Agreement is terminated pursuant to clause (iv), (v) or (vi) of this Section
9(a), such termination shall be effective 30 days after delivery of the notice
of termination.

                                      -5-
<PAGE>

      (b) "Cause" Defined. "Cause" means:

            (i) The Employee has breached the provisions of Section 5, 7 or 8 of
      this Agreement in any material respect,

            (ii) The Employee has engaged in willful and material misconduct,
      including willful and material failure to perform the Employee's duties as
      an officer or employee of the Company and has failed to cure such default
      within 30 days after receipt of written notice of default from the Board
      of Directors.

            (iii) The Employee has committed fraud, misappropriation or
      embezzlement in connection with the Company's business, or

            (iv) The Employee has been convicted or has pleaded nolo contendere
      to serious criminal misconduct (excepting, for example, parking violations
      and occasional minor traffic violations).

In the event that the Company terminates the Employee's employment for "cause"
pursuant to clause (ii) of this Section 9(b) and the Employee objects in writing
to the Board's determination that there was proper "cause" for such termination
within 20 days after the Employee is notified of such termination, the matter
shall be resolved by arbitration in accordance with the provisions of Section
10(a). If the Employee fails to object to any such determination of "cause" in
writing within such 20 day period, he shall be deemed to have waived his right
to object to that determination. If such arbitration determines that there was
not proper "cause" for termination, such termination shall be deemed to be a
termination pursuant to clause (iv) of Section 9(a) and the Employee's sole
remedy shall be to receive the wage continuation benefits contemplated by
Section 9(g).

      (c) "Good Reason" Defined. "Good Reason" means:

            (i) a material reduction in the Employee's scope of authority or
      responsibility; or

            (ii) a reduction in the Employee's base salary.

In the event the Employee terminates his employment with "good reason" pursuant
to clause (i) of this Section 9 (c) and the Company objects in writing to the
Employee's determination that there was proper "good reason" for such
termination within 20 days after the Company is notified of such termination,
the matter shall be resolved by arbitration in accordance with the provisions of
Section 10(a). If such arbitration determines that there was not proper "good
reason" for termination, such termination shall be deemed to be a termination
pursuant to clause (vi) of Section 9(a).

      (d) Effect of Termination Notwithstanding any termination of this
Agreement, the Employee, in consideration of his employment hereunder to the
date of such termination, shall remain bound by the provisions of this Agreement
which specifically relate to periods, activities or obligations upon or
subsequent to the termination of the Employee's employment.

      (e) "Disabled" Defined. "Disabled" means any mental or physical impairment
or disorder that renders the Employee unable to perform the essential functions
of his position, with or without reasonable accommodation, for a period of 180
days during any continuous 360-day period.

      (f) Surrender of Records and Property. Upon termination of his employment
with the Company, the Employee shall deliver promptly to the Company all
records, manuals, books, blank forms, documents, letters, memoranda, notes,
notebooks, reports, data, tables, calculations or copies (both electronic and
hard copies) thereof that 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 that 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.

      (g) Salary Continuation. If the Employee's employment by the Company is
terminated by the Company pursuant to clause (i), (ii), (iv) or (v) of Section
9(a), the Company shall continue to pay to the Employee (or his heirs in the
case of (i)) his base salary and shall continue to provide health insurance
benefits for the Employee and his family (or his heirs in the case of (i)),
through the earlier of (a) the date that the Employee has obtained other
full-time employment, or (b) twelve months from the date of termination of
employment. If this Agreement is terminated pursuant to clauses (iii) or (vi) of
Section 9(a), the Employee's right to base salary and benefits shall immediately
terminate, except as may otherwise be required by applicable law. Additional
compensation, bonuses and benefits may be approved by the Board of Directors.

      10. Settlement of Disputes.

      (a) Arbitration. Except as provided in Section 10(b), any claims or
disputes of any nature between the Company and the Employee arising from or
related to the performance, breach, termination, expiration, application or
meaning of this Agreement or any matter relating to the Employee's employment
and the termination of that employment by the Company shall be resolved
exclusively by arbitration in Des Moines, Iowa, or in the home state of the
Company's corporate headquarters should the location change during the term of
this agreement, in accordance with the applicable rules of the American
Arbitration Association. In the event of submission of any dispute to
arbitration, each party shall, not later than 30 days prior to the date set for
hearing, provide to the other party and to the arbitrator(s) a copy of all
exhibits upon which the party intends to rely at the hearing and a list of all
persons each party intends to call at the hearing. The fees of the arbitrator(s)
and other costs incurred by the Employee and the Company in connection with such
arbitration shall be paid by each party. The decision of the arbitrator(s) shall
be final and binding upon both parties. Judgment of the award rendered by the
arbitrator(s) may be entered in any court of competent jurisdiction.

      (b) Venue. Any action at law, suit in equity or judicial proceeding
arising directly, indirectly, or otherwise in connection with, out of, related
to or from this Agreement, or any provision hereof, shall be litigated only in
the courts of the State of Iowa, located in Story County or in the federal
courts located in Des Moines, Iowa or in the home state of the Company's
corporate headquarters should the location change during the term of this
agreement. The Employee and the Company consent to the jurisdiction of such
courts over the subject matter set forth in Section 10(b).

      11. Miscellaneous.

      (a) Entire Agreement. This Agreement (including the exhibits, schedules
and other documents referred to herein) contains the entire understanding
between the parties hereto with respect to the subject matter hereof and
supersedes any prior understandings, agreements or representations, written or
oral, relating to the subject matter hereof.

      (b) Counterparts. This Agreement may be executed in separate counterparts,
each of which will be an original and all of which taken together shall
constitute one and the same agreement, and any party hereto may execute this
Agreement by signing any such counterpart.

      (c) Severability. Whenever possible, each provision of this Agreement
shall be interpreted in such a manner as to be effective and valid under
applicable law but if any provision of this Agreement is held to be invalid,
illegal or unenforceable under any applicable law or rule, the validity,
legality and enforceability of the other provision of this Agreement will not be
affected or impaired thereby. In furtherance and not in limitation of the
foregoing, should the duration or geographical extent of, or business activities
covered by, 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.

      (d) Successors and Assigns. This Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective heirs, personal
representatives and, to the extent permitted by subsection (e), successors and
assigns.

      (e) Assignability. Neither this Agreement nor any right, remedy,
obligation or liability arising hereunder or by reason hereof shall be
assignable (including by operation of law) by either party without the prior
written consent of the other party to this Agreement, except that the Company
may, without the consent of the Employee, 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 11.

      (f) Modification, Amendment, Waiver or Termination. No provision of this

in writing signed by the parties to this Agreement. No course of dealing between
the parties will modify, amend, waive or terminate any provision of this
Agreement or any rights or obligations of any party under or by reason of this
Agreement. No delay on the part of the Company in exercising any right hereunder
shall operate as a waiver of such right. No waiver, express or implied, by the
Company of any right or any breach by the Employee shall constitute a waiver of
any other right or breach by the Employee.
