      during the period in which this report is being prepared;





b)
      Designed such internal control over financial reporting, or caused such internal

      with generally accepted accounting principals;

      Evaluated the effectiveness of the registrant’s disclosure controls and

      All
      significant deficiencies and material weaknesses in the design or operation

      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
