| | (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 business issuer, including its

               particularly during the period in which this 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

          financial reporting, to the small business issuers auditors and the audit
          committee of the small business issuer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

               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.
