         Cirond may prepay all or any  portion of this Note  without  penalty or

demands  and notices of any kind in  connection  with the  execution,  delivery,
performance and enforcement of this Note are hereby waived.

not  performed  when due.  This Note shall be  governed  by, and  construed  and
interpreted in accordance with, the laws of the State of California.

         This Note  provides  further  evidence of the  obligations  of Servgate

one of its officers thereunto duly authorized on the date hereof.
