(a) Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to

consolidated subsidiaries, is made known to us by others within those entities, particularly during the period in

which this report is being prepared;

control over financial reporting; and

5. The registrant’s other certifying officer(s) 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 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.
