     (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 Company,  including its

     being prepared;

     process, summarize and report financial information; and

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