| 5.                                      | The      registrant's other certifying officer and I have disclosed, based on our      most recent evaluation of internal control over financial reporting, to      the registrant's auditors and the audit committee of the registrant's      board of directors (or persons performing the equivalent      functions):  |
|                                    | (a)      all significant deficiencies and material weaknesses 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 |
|                                    | (b)      any fraud, whether or not material, that involves management or other      employees who have a significant role in the registrant's internal control      over financial reporting. |
