|  
|2. | Based on my knowledge, this report does not contain any untrue
    statement of a material fact or omit to state a material fact
    necessary to make the statements made, in light of the
    circumstances under which such statements were made, not
    misleading with respect to the period covered by this report;                              
|  
|3. | Based on my knowledge, the financial statements, and other
    financial information included in this report, fairly present in
    all material respects the financial condition, results of
    operations and cash flows of the registrant as of, and for, the
    periods presented in this report;                                                 
|  
|4. | The registrants other certifying officer and I are

    defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for
    the registrant and have:

    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

    registrants internal control over financial reporting that
    occurred during the registrants most recent fiscal quarter

    likely to materially affect, the registrants internal
    control over financial reporting; and



|   |

| |                                                                                                                                                                                                                                                                                             
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
| | 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

| | b) Any fraud, whether or not material, that involves
    management or other employees who have a significant role in the
