               i.   All  significant  deficiencies in the design or operation of
                    internal  controls which could adversely affect the issuer's
                    ability to record,  process,  summarize and report financial
                    data and  have  identified  for the  issuer's  auditors  any
                    material weaknesses in internal controls; and ii. Any fraud,
                    whether or not material,  that involves  management or other
                    employees  who  have a  significant  role  in  the  issuer's
                    internal controls; and

(6)  I and the other certifying officers have indicated in the report whether or
     not there were significant changes in internal controls or in other factors
     that could significantly affect internal controls subsequent to the date of
