|   | 4.  The registrant’s other certifying      officer and I are responsible for establishing and maintaining disclosure      controls and procedures (as      defined      in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over      financial reporting (as defined in Exchange Act      Rules      13a-15(f) and 15d-15(f)) for the registrant and    have: |
|--------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (a)  Designed such disclosure controls      and procedures, or caused such disclosure controls and procedures to be      designed under our            supervision, to ensure that material information relating to the      registrant, including its consolidated subsidiaries, is made                 known to us by others within those entities, particularly during the      period in which this report is being  prepared; |
|--------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (b)  Designed such internal control      over financial reporting, or caused such internal control over financial      reporting to be designed            under our supervision, to provide reasonable assurance regarding the      reliability of financial reporting and the preparation of                 financial statements for external purposes in accordance with generally      accepted accountingprinciples; |
|--------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (c)  Evaluated the effectiveness of the      registrant’s disclosure controls and procedures and presented in this      report our conclusions            about the effectiveness of the disclosure controls and procedures, as of      the end of the period covered by this report based on            such evaluation; and |
|--------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | (d)  Disclosed in this report any      change in the registrant’s internal control over financial reporting that      occurred during the            registrant’s fourth fiscal quarter that has materially affected, or is      reasonably likely to materially affect, the registrant’s                 internal control over financial reporting;  and |
|--------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|

|   | 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. |
