| a)   | All              significant deficiencies in the design or operation of internal control              over financial reporting which are reasonably likely to adversely affect              the registrant's ability to record, process, summarize and report              financial information; and |
|----------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
