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 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

              affected, or is reasonably likely to materially affect, the
              registrant's internal control over financial reporting;

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

directors (or persons performing the equivalent function):

          a.  all significant deficiencies 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;
