      (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 business issuer,

      is being prepared;

      affected, or 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, to the small business issuer's auditors and the audit committee

      the equivalent functions):

      (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

      (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 control over financial reporting.
