      Based
      on my knowledge, the report does not contain any untrue statement of a material
      fact or omit to state a material fact necessary to make the statements made,
      in
      light of the circumstances under which such statements were made, not misleading

4.
      The

      and
      maintaining disclosure controls and procedures (as defined in Exchange Act
      Rules
      13a-15(c) and 15d-(e)) 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 Registrant, including its consolidated subsidiaries,
      is made known to us by others within those entities, particularly during the
      period in which this report is being prepared;

      Registrant's internal control over financial reporting; and





5.
      The
      registrant's other certifying officers and I have disclosed, based on our most
      recent evaluation, to the registrant's auditors and the audit committee of
      the

      functions):





a)
      all
      significant deficiencies in the design or operation of internal controls which
      could adversely affect the registrant's ability to record, process, summarize
      and report financial data and have identified for the registrant's auditors
      any
      material weaknesses in internal controls (all of which do not apply);
      and





b)
      any
      fraud, whether or not material, that involves management or other employees
      who
      have a significant role in the registrant's internal controls, (all of which
      do
      not apply).
