                   a.  designed such disclosure controls and procedures, or caused such disclosure controls and

                        is being prepared;

                   b.  designed such internal control over financial reporting, or caused such internal control over

                         control over financial reporting which are reasonably likely to adversely affect the
                         Company'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 Company's internal control over financial reporting.
