us by others within those entities, particularly during the period in
which this quarterly report is being prepared;

and procedures and presented in this quarterly report our conclusions

5. The registrant's other certifying officers and I have disclosed, based on
our most recent evaluation of internal controls over financial reporting,
to the registrant's auditors and the audit committee of registrant's board
of directors (or persons performing the equivalent function):
a) all significant deficiencies and material weaknesses in the design or
operation of internal controls over financial reporting which
adversely affect the registrant's ability to record, process,
summarize and report financial information; and
