reasonable assurance regarding the reliability of financial reporting and the

registrant's auditors and the audit committee of the registrant's board of
directors (or persons performing the equivalent functions):

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
