Dear Bob:

       This letter will serve as our agreement to extend the lease you
presently have with E&E Investments, for units 100-600 of 5100 West Silver
Springs Blvd., which expires on December 31, 2000, for one year ending December
31, 2001. The new lease is being prepared which will indicate the extension and
also granting you an additional one year option to extend through December 31,

       I hope this will suffice until the new lease is prepared, which will be
very shortly.

       Thank You.

Sincerely,
