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 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):
