2.
            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

      control over financial reporting (as defined in Exchange Act Rules
      13a-15(f) and 15d-15(f)) for the registrant and we
  have:





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

subsidiaries, is made known to us by others within those entities, particularly
during the period in which this quarterly report is being prepared;

registrant’s internal control over financial reporting; and





5.
            The
      registrant’s other certifying officer and I have disclosed, based on our
      most recent evaluation of internal controls over financial reporting, to

      directors (or persons performing the equivalent
  function);

significant deficiencies and material weaknesses in the design or operation of

to  adversely affect the registrant’s ability to record, process,
summarize and report financial information; and

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.
