          or proceeding of any kind against the Company based on, arising out of

          against the company on account of any matters over which he has waived
          his rights in this  Agreement,  Employee  agrees to indemnify and hold
          the Company harmless from any damages or costs incurred by the Company

          entitled  to assert any claims of any kind  against the Company on his
          behalf,  and he agrees to  indemnify  and hold  harmless  the  Company
          against any such claims that may be asserted by any other person.

     11.  Employee  represents  and warrants that no other person other than the

          and exclusive authority to execute the Agreement; and he has not sold,
          assigned, transferred, conveyed, or otherwise disposed of any claim or
          demand relating to any matter covered by the Agreement.

     12.  Employee  waives any  claims for  reimbursement  for any  expense  not
          submitted  in writing  prior to the date he  executes  the  Agreement.

          obligations  on behalf of the Company  effective  July 17, 1998 and he

          goodwill and reputation of the Company and the products or services it
          provides.  Likewise, the Company agrees not to do or say anything that
          reasonably may be expected to have the effect of disparaging  Employee

          breach  of  the  Agreement.  Furthermore,  Employee  and  the  Company
          understand  that if the  Agreement  is breached  in any  manner,  both
          parties  will have the right to pursue all  remedies in law or equity.

          choice,  with respect to said claims and the  Agreement;  and that the
          Company's attorney and Employee's attorney, are authorized to take all
          action  necessary  to complete the  Agreement.  The  Agreement  may be
          amended,  modified, or changed only by an agreement in writing that is
          signed by both parties.

          claims of the Company, to the reasonable  satisfaction of the Company,
          prior to the Company  taking any final  action to cancel or  terminate
          the severance benefit granted hereunder.

     23.  Should  any  term,  section,  or  portion  of the  Agreement  be  held
          unreasonable or  unenforceable by any court, the decision of the court
          will apply only to the specific term,  section,  or portion  involved,
          and it will not invalidate  the remaining  sections or portions of the
          Agreement.

     24.  Until  Employee  signs the  Agreement  and returns it to the  Company,
          Employee will not receive the  consideration  named in ss.1 above.  If
          Employee  chooses  not to fully  execute  the  Agreement,  he will not
