                the company 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

      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

      of financial statements for external purposes in accordance with generally
      accepted accounting principles;





(c)  Evaluated
      the
      effectiveness of the company's disclosure controls and procedures and presented

      affected, or is reasonably likely to materially affect, the company's internal
      control over financial reporting; and





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