                  (a) Designed such disclosure controls and procedures, or
         caused such disclosure controls and procedures to be designed under our
         supervision, to ensure that material information relating to the small

         report) that has materially affected, or is reasonably likely to
         materially affect, the small business issuer's internal control over
         financial reporting; and

                  (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 small business
         issuer's ability to record, process, summarize and report financial
         information; and
