		control over financial reporting; and
5	.	The registrant’s other certifying officer and I have disclosed, based on our most recent evaluation of internal

		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.
