    Based on my knowledge, this quarterly report does
not contain any untrue statement of a material fact or
omit to state a material fact necessary to make the
statements made, in light of the circumstances under
which such statements were made, not misleading with
respect to the period covered by this quarterly report;3.
    
    Based on my knowledge, the financial statements, and
other financial information included in this quarterly
report, fairly present in all material respects the
financial condition, results of operations and cash flows
of the registrant as of, and for, the periods presented
in this quarterly report;4.
    
    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)) for the registrant and we 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 supervision, to
provide reasonable assurance regarding
the reliability of financial reporting
and the preparation of financial
statements for external purposes in
accordance with accounting principles
generally accepted in the United States
of America;c)
    
    evaluated the effectiveness of the
registrants disclosure controls and
procedures and presented in this report
our conclusions about the effectiveness
of the disclosure controls and
procedures, as of the end of the period
covered by this report based on such
evaluation; andd)
    
    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 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.
