to materially affect, the registrant's internal control over
financial reporting; and
5. The registrant's other certifying officer 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 the registrant's board of directors (or persons

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

or other employees who have a significant role in the
registrant's internal control over financial reporting.
