                The
                    registrant's other certifying officer(s) 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)) and internal
                    controls over financial reporting (as defined in Exchange Act
                    Rules
                    13a-15(f) and 15d-15(f)) for the registrant 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 registrant, 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)  Designed
      such internal control over financial reporting, or caused such internal control
      over financial reporting to be designed under our supervision, to provide
      reasonable assurance regarding the reliability of financial reporting and the
      preparation of financial statements for external purposes in accordance with
      generally accepted accounting principles;




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




5.
            The
                registrant's other certifying officer(s) and I have disclosed, based
                on
                our most recent evaluation of internal control over financial reporting,
                to the registrant's auditors and the audit committee of the registrant'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 registrant'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 registrant's internal control over financial
      reporting.
