(a)  Designed
      such disclosure controls and procedures, or caused such disclosure controls
      and
      procedures to be designed under our supervision, to ensure that material

      materially affect, Rotoblock Corporation's internal control over financial
      reporting; and

      and report financial information; and

      fraud, whether or not material, that involves management or other employees
