in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and we
have:

      a)  Designed such disclosure controls and procedures, or caused such

prepared;

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

      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

other employees who have a significant role in the registrant's internal
control over financial reporting.
