6. Covenant Not to Compete.

          6.1 During the Term of this Agreement (or, if longer,  during the term
     of Employee's employment with the Company or any of its affiliates) and for

          6.2 During the Term of this Agreement (or, if longer,  during the term
     of Employee's employment with the Company or any of its affiliates) and for
     a period of twelve (12) months after  termination of this Agreement (or, if
     later,  termination of Employee's employment with the Company or any of its
     affiliates), Employee shall not (i) directly or indirectly cause or attempt
     to cause any employee of the Company or any of its  affiliates to leave the

          6.3 Employee agrees that, because of the nature and sensitivity of the
     information  to  which he will be  privy  and  because  of the  nature  and
     national  and   international   scope  of  the  Company's   business,   the
     restrictions contained in this Section 6 are fair and reasonable.

     sole  property  of the  Company  and shall be deemed  trade  secrets of the
     Company.

          7.5 Upon termination of Employee's  employment  pursuant to any of the
     provisions herein,  Employee or his legal  representative  shall deliver to
     the  Company  all  originals  and  all  duplicates  and/or  copies  of  all
     documents,  records,  notebooks,  and similar repositories of or containing
     Confidential Information or subject matter then in his possession,  whether
     prepared by him or not.

          7.6 Employee  agrees that the  covenants and  agreements  contained in
     this Section 7 are fair and reasonable  and that no waiver or  modification
     of this  Section or any  covenant or  condition  set forth  herein shall be
     valid unless set forth in writing and duly executed by the parties  hereto.
     Employee  agrees to  execute  such  separate  and  further  confidentiality
     agreements embodying and enlarging upon the provisions of this Section 7 as
     the Company may reasonably request.

                                      -5-

     construed as  prohibiting  the Company from pursuing any other remedies for
     such  breach or  threatened  breach,  including  recovery  of damages  from
     Employee.

          9. No Waiver.  A waiver by the Company of a breach of any provision of
     this Agreement by Employee shall not operate or be construed as a waiver of
