investments are made.

         6. DISCLOSURE OF INFORMATION. Employee recognizes and acknowledges that

the Board.  The Employee  further  agrees not to divulge or publish or authorize
anyone  else to divulge or  publish  during or after the term of this  Agreement
knowledge of said secret  processes I  procedures,  list of  customers,  bidding
methods,  discoveries  or  inventions  or  any  other  confidential  information
acquired in the course of his employment concerning the Employer's business.

         8. RESTRICTIVE COVENANT - NON-COMPETITION.  Employee agrees that on the
termination for any reason  whatsoever of his employment  with the Employer,  he

directly or indirectly  engage in or own any part of any company  engaged in the
same or similar competitive line of business carried on by the Employer or work,
on a full-time, part-time or consultant basis, for any corporation, partnership,
sole  proprietorship  or any other  legal  entity  engaged in such  business  or
similar competitive line of business within any of the States of Iowa, Illinois,
Indiana or Minnesota, nor will he in any way directly or indirectly,  attempt to
hire the  Employer's  employees or take away any of the  Employer's  business or
customers or destroy,  injure or damage the  goodwill of the  Employer  with its
customers.

         Employee  further  agrees  that in the  event  that the  Employer,  its
successors or assigns,  shall bring any action for the enforcement of any or all
provisions of this  covenant not to compete,  and if the Court shall find on the
basis of the  evidence  introduced  in said  action  that  this  paragraph  8 is
unreasonable  then the Court shall make a finding as to what is  reasonable  and
shall  enforce  this  Agreement  by  judgment  or decree  to the  extent of such
finding.

         9. OWNERSHIP OF INVENTIONS.  Employee  promises and agrees that he will
disclose  fully  and  reveal  promptly  to  Employer  any  and  all  inventions,
discoveries,  processes, methods, designs, products and know-how, which Employee
may invent,  discover,  acquire or develop,  either alone or in conjunction with
others,  during  Employee's  employment  by Employer  (hereinafter  collectively
referred to as  "Discoveries"),  where said Discoveries (i) relate to, or in any
way pertain to or are  connected  with the  business of  Employer,  or (ii) were

or  indirectly  from such  employment  by  Employer,  or relate to  articles  or
products made,  sold, used or bought by Employer,  or (iv) were being considered
for  design,  development,  sale,  purchase  or  use  by  Employer  during  such
employment  by  Employer,  and  Employee  further  promises and agrees that said
Discoveries shall be the sole and exclusive property of Employer;  and Employee,
whenever  requested to do so by Employer,  and without  further  compensation or
consideration  shall properly execute any and all applications,  assignments and
other  instruments which Employer shall deem necessary in order to (a) apply for
and obtain, in the name of Employer,  a patent,  trademark or copyright for said
Discoveries, and (b) assign and convey to Employer the sole and exclusive right,
title and interest in and to said Discoveries,  and any  applications,  patents,
trademarks or copyrights  thereon.  Employee  hereby  warrants,  represents  and
confirms that he neither holds nor has any interest in any patent, patent right,
patent  application,  trademark,  trademark  application,  license  agreement or
copyright  related in any way to the business of Employer;  and Employee further
agrees that any future  application for any patent,  patent right,  trademark or
copyright for any of said Discoveries shall be made in the name of Employer.


                                        3


         Employee  agrees that, in the event that  subsequent to his employment,
his assistance is needed to secure, defend, or enforce any patent,  trademark or
copyright,  Employee  will provide any such  assistance  and  Employer  will pay
reasonable compensation for his time at a rate to be negotiated.

         Employee acknowledges that the restrictions contained in this paragraph
9 are  reasonable  and  necessary  in order  to  protect  Employer's  legitimate
business  interests and any violation thereof would result in irreparable injury
to Employer.  Employee further  acknowledges and agrees that in the event of any
violation  hereof,  Employer shall be authorized and entitled to seek,  from any
court of  competent  jurisdiction,  (i)  preliminary  and  permanent  injunctive
relief;  (ii) an equitable  accounting of all profits or benefits arising out of
the  violation;  and (iii)  damages  arising  from the  breach.  Such  rights or
remedies  shall be cumulative and in addition to any other rights or remedies to
which Employer may be entitled.  The prevailing  party in any such lawsuit shall
further be entitled to recover his reasonable  attorneys,  fees, court costs and
expenses,

         Employer's  failure  to  exercise a right  hereunder  in the event of a
breach by Employee of any term hereof shall not be construed as a waiver of such
breach or prevent Employer from thereafter  enforcing strict compliance with any
and all terms of this Employment Agreement.

         10.      TERMINATION OF AGREEMENT.

                  (a)      Employer may terminate this Agreement, effective

occurrence of any of the following:

                           (i)     Failure or refusal of Employee to perform his
                  duties and obligations under this Agreement;

                           (ii)     Death of Employee; or

                           (iii)    Disability of Employee, defined as an
                  inability to perform his work for 45 consecutive days,
                  or for 90 days within any 12-month period; or

                           (iv) The  commission by Employee of any felony or any
                  other act constituting fraud, embezzlement or misappropriation
                  of funds (civil or criminal).

In the event of a termination  pursuant to this  paragraph  10(a),  compensation
shall be paid on a prorated  basis through the date of  termination,  subject to
any rights of offset of Employer.

                  (b) Employer may terminate  this  Agreement for any reason not
specified in paragraph 10(a) hereof, effective on a date designated in a written

                                        4


notice to Employee.  In the event of a  termination  pursuant to this  paragraph
10(b),  Employee's  compensation  shall be paid on a prorated  basis through the
effective date of termination,  subject to any rights of offset of Employer; and
in addition, Employee shall be paid a termination payment equal to $26,250. Such
termination  payment shall be subject to any rights of offset of Employer.  Such
termination  payment  shall  be  paid  in  12  equal,  consecutive  semi-monthly
installments.  Termination payment installments shall be made, until fully paid,
on the same days  following  Employee's  termination  that  Employee  would have
otherwise  received  his regular  semi-monthly  salary  payments had he not been
terminated.

                  (c)  Employee may  terminate  this  Agreement  upon sixty (60)
days'  prior  written  notice.  In the event of a  termination  pursuant to this
paragraph 10(c), compensation shall be paid on a prorated basis through the date
of termination, subject to any rights of offset of Employer.

         11.  WAIVER OF BREACH.  The waiver by the Employer of the breach of any
provisions of this  Agreement by Employee shall not operate or be construed as a
waiver of any subsequent breach by Employee.

         12.  APPLICABLE  LAW. This Agreement and the validity of this provision
shall be construed under the laws of the State of Iowa.

         13. ENTIRE AGREEMENT.  This instrument constitutes the entire agreement
of the parties and  supersedes  and replaces all  previous  agreements,  whether
written  or oral,  relating  to the  employment  relationship  of  Employer  and
Employee.  It may not be  changed  orally  but only by an  agreement  in writing
signed  by  the  party  against  whom   enforcement   of  any  waiver,   change,
modification, extension or discharge is sought.

         14. SEPARABILITY OF PROVISIONS. In the event that any provision of this
Agreement is found by a Court to be void or  unenforceable,  the provision shall
be construed to be separable from the other provisions of this Agreement,  which
shall retain full force and effect.
