during the period in which this report is being prepared;

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 registrant's board of directors

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.
