establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and 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 Company,
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;

                  (b) evaluated the effectiveness of the Company's disclosure

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

         (5) The Company's other certifying officer and I have disclosed, based
on our most recent evaluation of internal control over financial reporting, to
the Company's auditors and the audit committee of the Company's board of
directors (or persons performing equivalent functions):

                  (a) all significant deficiencies in the design or operation of
internal controls which are reasonably likely to adversely affect the Company's
ability to record, process, summarize and report financial data; and any fraud,
whether or not material, that involves management or other employees who have a
significant role in the Company's internal controls.
