                  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 small

         in which this report is being prepared;

         small business issuer's internal control over financial reporting;

5. The small business issuer's other certifying officer(s) and I have disclosed,
based on our most recent evaluation of internal control over financial
reporting, to the small business issuer's auditors and the audit committee of

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 small business issuer'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 small
         business issuer's internal control over financial reporting.
