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
     controls over financial reporting.
