were deleted, the

<PAGE>

period thereof reduced or the range of activities or areas covered thereby
reduced in scope, the said restrictions will be deemed to apply with such
modifications as may be necessary to make them valid and effective and any
such modification shall not thereby effect the validity of any other
restriction contained therein.

Intellectual Property. The Employee acknowledges that he will develop and be
exposed to information that is or will be confidential and proprietary to the
Company. The information includes customer lists, marketing plans, pricing
