a)

Designed  such  disclosure  controls  and  procedures,  or caused  such disclosure  controls and  procedures to be designed  under our  supervision,  to ensure  that  material  information  relating  to  the  small  business  issuer, including its  consolidated  subsidiaries,  is made known to us by others within those  entities,  particularly  during the period in which this  report is being prepared;
