     a.   all significant deficiencies in the design or operation of internal
          controls which could adversely affect the registrant's ability to
          record, process, summarize and report financial data and have
          identified for the registrant's auditors any material weaknesses in
          internal controls; and

     b.   any fraud, whether or not material, that involves management or other
          employees who have a significant role in the registrant's internal
          controls; and

     report whether or not there were significant changes in internal controls
     or in other factors that could significantly affect internal controls
     subsequent to the date of our most recent evaluation, including any
     corrective actions regarding significant deficiencies and material
