               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 registrant, including its consolidated

               during the period in which this annual report is being prepared;

               control over financial reporting that occurred during the small business
               issuers most recent fiscal quarter (the small business issuer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

          based on our most recent evaluation of internal control over financial

          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 small business issuers ability to record, process,
               summarize and report financial information; and
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | b)
