                                         that occurred during the registrant's most recent fiscal quarter (the registrant's fourth
                                         fiscal quarter in the case of an report) that has materially affected, or is reasonably
                                         likely to materially affect, the registrant's internal controls over financial reporting;
                                         and,

| | a) | all
                                         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
