such violation within five (5) days of written notification of such violation
from the other party. Such cancellation shall not excuse the breach or
non-performance by the other party or relieve the breaching party of its
obligation incurred prior to the date of cancellation, including, without
limitation, the obligation of Client to pay the nonrefundable consideration
described in paragraph B.4. hereof.

         3. Due Diligence. The Client shall supply and deliver to the

               Client for any reason (regardless of paragraph B.2. above),
               within the first fifty (50) days from the date of the Agreement.
