Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the Company and Employee and their respective successors, executors, administrators, heirs and/or permitted assigns; provided, however, that neither Employee nor the Company may make any assignments of this Agreement or any interest herein, by operation of law or otherwise, without the prior written consent of the other parties hereto. 14.

B. In the event that Employee shall be in breach of any of the restrictions contained in Section 8 hereof, then the Restricted Period shall be extended for a period of time equal to the period of time that Employee is in breach of such restriction. 23.
