         4. The registrant's other certifying officers and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-14 and 15d-14) for the registrant and have:

              such disclosure controls and procedures to be designed under our
              supervision, to ensure that material information relating to the
              registrant is made known to us by others within this entity,

              being prepared;

              based on such evaluation; and

              (c) disclosed in this report any change in the registrant's

              registrant's most recent fiscal quarter (the registrant's fourth
              fiscal quarter in the case of an annual report) that has
              materially affected, or is reasonably likely to materially affect,
              the small business issuer's internal control over financial
              reporting; and

              (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
