    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.
