| | c) | Disclosed in this report any changes in the small
      business issuers internal 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;

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 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 adversely affect the small business issuers
      ability to record, process, summarize and report financial information;
      and
