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

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;

reporting to be designed under our supervision, to provide reasonable assurance regarding the reliability

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 officers 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 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.
