                 ------------------

terminate his or her employment, except as otherwise may be required in the
performance of Employee's duties to ISE or DTS.

          Notwithstanding the foregoing, Employees may own, directly or

Bonus and Other Compensation as set forth in sections 1.2.1 and 1.2.2 under the
terms therein (unless such amounts have already been paid to Employee); and any
