                              EMPLOYMENT AGREEMENT

abilities in the business of the Company to serve as Vice President and
Actuary; and

         Whereas, the Employee desires to enter into such arrangement with the

         Now, THEREFORE, in consideration of the mutual covenants and promises
contained herein, the Company and Employee agree and state as follows:

                               ARTICLE 1 - DUTIES

         The Employee shall serve as Vice President and Actuary of the Company.
The Employee, while serving as Vice President and Actuary, shall have the
powers and duties generally ascribed to such offices and such additional

President of the Company.

                                ARTICLE 2 - TERM

         This agreement shall begin August 23, 1993 and continue until

insurance, or sell or perform insurance related services (except in behalf of
an Insurance Carrier who is not in competition with Clark/Bardes, Inc., or to a
competitive firm who already has a relationship with a Clark/Bardes client.
Any such relationship will be clearly documented in the exit agreement.) to (i)
any client of the Company at the time of such termination, or (ii) any former

the Company.

         This provision shall not preclude the Employee from performing
insurance related services for any Clark/Bardes, Inc., client where such
services are required as part of an Employment Agreement of a competitive firm
and where such services do not directly involve the solicitation or selling of
insurance.

                         ARTICLE 5 - EMPLOYEE BENEFITS
