Employment Agreement shall remain in full force and effect as previously
executed by the parties, and the parties hereby ratify the Employment Agreement
as amended hereby.

     5. Waiver of Breach. The waiver by any party to a breach of any provision
in this Amendment cannot operate or be construed as a waiver of any subsequent
breach by a party.

provision of this Amendment shall not affect the other provisions hereof, and
this Amendment shall be construed in all respects as if the invalid or
