registrant and have:
 a)
    
    Designed such disclosure controls and procedures,
or caused such disclosure controls and procedures

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 the financial

external purposes in accordance with generally
accepted accounting principles;c)

    Disclosed in this 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 evaluation of internal control over
financial reporting, to the registrants auditors and the audit
committee of 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; 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.
