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)

accordance with generally accepted accounting principles;c)

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

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(s) and I have

financial reporting, to the registrants auditors and the 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; 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.
