significant deficiencies and material weaknesses in the design or operation of
internal controls over financial reporting which are reasonably likely
to  adversely affect the registrant’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 controls over
financial reporting.
