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

      reporting; and

      5.    The company's other certifying officer and I have disclosed, based

      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 significant role in the company's internal
