    Based on my knowledge, this quarterly report does

    The registrants other certifying officer and I are

    designed such disclosure controls and
procedures, or caused such disclosure

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

accordance with accounting principles
generally accepted in the United States
of America;c)
    
    evaluated the effectiveness of the

evaluation; andd)

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 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 controls 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.
