to materially affect, the registrant's internal
control over financial reporting; and
5. The registrant's other certifying officer(s) and I have disclosed
to the registrant's auditors and the audit committee of the
registrant's board of directors (or persons performing the
equivalent functions):
(a) All significant deficiencies and material weaknesses
in the 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
(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.
