  necessary to make the statements made, in light of the circumstances
  under which such statements were made, not misleading with respect to
  the period covered by this report;

3.Based on my knowledge, the financial statements, and other

  and internal control over financial reporting (as defined in Exchange
  Act Rules 13a-15(f) and 15d-15(f)) for the registrant 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 information relating to the

      us by others within those entities, particularly 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 designed

      control over financial reporting that occurred during the registrant's
      most recent fiscal quarter (the registrant's fourth fiscal quarter in

      reasonably likely to materially affect, the registrant's internal
      control over financial reporting; and

5.The registrant's other certifying officer(s) 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 directors (or persons

  (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

  (b) Any fraud, whether or not material, that involves management or
      other employees who have a significant role in the registrant's
      internal control over financial reporting.
