    NOW,
THEREFORE, in consideration of the mutual covenants contained in this Agreement,
and for other good and valuable consideration the receipt and adequacy of which
are hereby acknowledged, the parties hereto agree as follows:

     

    1.           Amendment to Escrow
Agreement.  Effective immediately upon the complete execution
of this Escrow Amendment, the definition of “Share Exchange Deliveries Deadline”
