            Based

      material fact or omit to state a material fact necessary to make the

      control over financial reporting (as defined in Exchange Act Rules
      13a-15(f) and 15d-15(f)) for the small business issuer and
      have:




a.   Designed
such disclosure controls and procedures, or caused such disclosure controls and
procedures to be designed under our supervision, to ensure that material

subsidiaries, is made known to us by others within those entities, particularly
during the period in which this report is being prepared;

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(s) 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
      of the small business issuer's board of directors (or persons performing
      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.
