Consultant agrees that, in the event of the termination of his retention as a consultant to the Company, he can obtain employment in business activities which are of a different or non-competing nature with his activities as a consultant to the Company; and the enforcement of a remedy hereunder by way of injunction will not prevent him from earning a reasonable livelihood.
