and to the extent required by law.

     7.   OTHER EMPLOYMENT.  During his employment with the Company,
Employee shall devote as much professional efforts to enhance the business

recognizes, acknowledges and agrees that as a result of or in connection
with his employment he will have access to and obtain certain Confidential
Information, as defined below, relating to the Company's business and not
generally known to the public or to the Company's competitors.  The
Employee recognizes, acknowledges and agrees that the Confidential
Information constitutes a valuable, special and unique asset to the
Company, access to and knowledge of which is essential to the performance
of the employee's duties. The Employee specifically agrees that, except as
directed by the Company's Board of Directors or its Chief Executive Officer
or as required by law, the Employee will not at any time during or after
the Term use or disclose any Confidential Information to any person
