The Registrant’s other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and

which this report is being prepared;
(b) Designed such internal control over financial reporting, or caused such internal control over financial reporting

over financial reporting; and

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.
