and have:

     a)  Designed  such  disclosure  controls  and  procedures,  or caused  such

control over financial reporting; and

     b) Any fraud,  whether or not material,  that involves  management or other
employees who have a significant  role in the small business  issuer's  internal
control over financial reporting.
