    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

    evaluated the effectiveness of the registrants disclosure
controls and procedures and presented in this report our conclusions about the

    disclosed in this report any change in the registrants
internal control over financial reporting that occurred during the registrants

Audit Committee of the registrants board of directors (or persons performing the equivalent
functions):

    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.
