         a)       designed such disclosure controls and procedures, or caused

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

         b)       evaluated the effectiveness of the registrant's disclosure

materially affect, the 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 control over financial reporting, to
the registrant's auditors and the audit committee of the registrant's board of
directors (or persons performing the equivalent functions):

         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

         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.
