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

employees who have a significant role in the registrant's internal controls; and

6. The registrant's other certifying officer and I have indicated in this report

factors that could significantly affect internal controls subsequent to the date
