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

5. The registrant's other certifying  officer(s) and I have disclosed,  based on
our most recent evaluation of internal control over financial reporting,  to the
registrant's  auditors  and the audit  committee  of the  registrant's  board of
directors (or persons performing the equivalent 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.
