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

          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

          for external purposes in accordance with generally accepted accounting
          principles;

        registrant’s internal control over financial reporting; and

        registrant’s other certifying officer 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

  (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

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