15d-l5(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.

of financial statements for external purposes in accordance with generally accepted
accounting principles;c.
    
    Evaluated the effectiveness of the registrants disclosure controls and procedures

    Disclosed in this quarterly report any change in the registrants internal control
over financial reporting that occurred during the registrants most recent fiscal quarter
(the registrants fourth fiscal quarter in the case of an annual report) 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

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;
andb)
    
    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.
