          a)     Designed  such  disclosure  controls  and procedures, or caused
such disclosure controls and procedures to be designed under our supervision, to

materially  affect,  the registrant's internal control over financial reporting;
and

     5.     The  registrant's  other  certifying  officer  and I have disclosed,
based  on  our  most  recent  evaluation  of  internal  control  over  financial

functions):

          a)     All  significant  deficiencies  and  material weaknesses in the
design  or  operation  of  internal  control  over financial reporting which are
reasonably  likely  to  adversely  affect  the  registrant's  ability to record,
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 registrant's internal control
over  financial  reporting.
