3.
            Based
                on my
                knowledge, the financial statements, and other financial information
                included in this report, fairly present in all material respects

4.
            The
                registrant’s other certifying officers 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
                control 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

      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 officers 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.
