                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

            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

                process, summarize and report financial information ;
                and
