of, and for, the periods presented in this report;

4. I am the registrant's certifying officer and I are responsible for

reporting (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
registrant and I 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;

annual report) that has materially affected, or is reasonably likely to
materially affect, the registrant's internal control over financial reporting;
and

5. As the registrant's certifying officer, I have disclosed, based on our most
recent evaluation of internal controls over financial reporting, to the
registrant's auditors and the audit committee of registrant's board of directors
(or persons performing the equivalent function):

      a) all significant deficiencies in the design or operation of internal
control over financial reporting which 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.
