2.  Based
      on
      my knowledge, this quarterly report does not contain any untrue statement of
      a
      material 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

      for, the periods presented in this report;

      business issuer’s other certifying officer and I are responsible for
      establishing and maintaining disclosure controls and procedures (as defined
      in
      Exchange Act Rules 13a-15(e) and 15d-15(e)) 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
      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

      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 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 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 control over
      financial reporting.
