If any restriction set forth in this Subsection 7(b) is found by a court of competent jurisdiction or arbitrator to be unenforceable because it extends for too long a period of time or over too great a range of activities or in too broad a geographic area, it shall be interpreted to extend only over the maximum period of time, range of activities or geographic area as to which it may be enforceable. (c) Employee shall hold in a fiduciary capacity for the benefit of CMDC and Comtech all confidential information, knowledge or data relating to CMDC and Comtech or any of its other subsidiaries, and their respective businesses obtained by Employee before or during the period in which he is employed by CMDC.
