made known to me by others within the Company, particularly during the period in
which this quarterly report is being prepared;

         a) all significant deficiencies (if any) in the design or operation of
internal controls which could adversely affect the registrant's ability to
record, process, summarize and report financial data and have identified for the
registrant's auditors any material weaknesses in internal controls; 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; and

6. I have indicated in this quarterly 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 our most recent
evaluation, including any corrective actions with regard to significant
deficiencies and material weaknesses.
