financial reporting that occurred during                   the registrants most recent
fiscal quarter (the registrants                   fourth fiscal quarter in the case of
an annual report) that                   has materially affected, or is reasonably likely
to materially                   affect, the registrants internal control over financial
                  reporting; and

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

control over financial reporting.
