       Based on my knowledge, this report does not contain any untrue statement
      of a material fact or omit to state a material fact necessary to make 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;





b)
       Designed such internal control over financial reporting, or caused such
      internal control over financial reporting to be designed under our supervision,

      directors (or persons performing the equivalent function):





a)
       all significant deficiencies and material weaknesses in the design or
      operation of internal controls 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.
