and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and
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

registrant, including its consolidated subsidiaries, is made known to me 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

in the registrant’s internal control over financial reporting that occurred

over financial reporting; and





5. As the registrant’s certifying
officer, I have disclosed, based on my 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 control over
financial reporting which are reasonably likely to adversely affect the
registrant’s ability to record, process, summarize and report financial
information; and





(b) 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.
