      have:





(a)
      Designed such disclosure controls and procedures, or caused such disclosure

      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

      summarize and report financial information; and
