registrant and we have:

      a)  Designed  such  disclosure  controls  and  procedures,  or caused such
disclosure  controls and  procedures to be designed  under our  supervision,  to

is reasonably likely to materially  affect, the small business issuer's internal
control over financial reporting; and

5. The small business  issuer's other  certifying  officer and I have disclosed,
based on our most recent evaluation of internal control over financial reporting

report financial data information and

      b) Any fraud,  whether or not material,  that involves management or other
employees who have a significant  role in the small business  issuer's  internal
controls over financial reporting.
