For a period of one (1) year after the termination of my employment with the Company (“Restrictive Period”), for any reason, whether by me or the Company, regardless of the reason, I shall not, for my own benefit or for the benefit of any third party, directly or indirectly, in any capacity (as an employee, independent contractor, owner or otherwise) participate in any of the following activities:

If a covenant is held to be unenforceable because of the area covered, the duration thereof and/or the scope thereof, I agree that the court making such determination shall have the power to reduce the area and/or the duration and/or scope thereof, and the covenant shall then be enforceable in its reduced form.
