      small business issuer’s officer responsible for establishing and maintaining
      disclosure controls and procedures (as defined in Exchange Act
      Rules 13a-15(e) and 15d-15(e)) and internal 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 my supervision, to ensure that
      material information relating to the small business issuer, including its
      consolidated subsidiaries, is made known to me by others within those entities,
      particularly during the period in which this report is being
      prepared;




(b)
      [INTENTIONALLY OMITTED]




(c)
      Evaluated the effectiveness of the small business issuer’s disclosure controls
      and procedures and presented in this report our conclusions about the
      effectiveness of the disclosure controls and procedures, as of the end of the
      period covered by this report based on such evaluation; and




(d)
      Disclosed in this report any change in the small business issuer’s internal
      control over financial reporting that occurred during the small business
      issuer’s most recent fiscal that has materially 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 certifying officer has 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.
