      fact or omit to state a material fact necessary to make the statements made,
      in
      light of the circumstances under which such statements were made, not misleading
      with respect to the period covered by this report;





3.
      Based
      on my knowledge, the financial statements, and other financial information

      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 information relating to the small business issuer, including its
      consolidated subsidiaries, is made known to us by others within those entities,
      particularly during the period in which this report is being
      prepared;





(b)
      Evaluated the effectiveness of the small business issuer's disclosure controls

      control over financial reporting that occurred during the small business
      issuer's most recent fiscal quarter (the small business issuer's fourth fiscal
      quarter in the case of an annual report) that has materially affected, or is
      reasonably likely to materially affect, the small business issuer's internal
      control over financial reporting; and





5.

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

      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.
