have:
|
|
a)
|
designed
such disclosure controls and procedures, or caused such disclosure

others within those entities, particularly during the period in
which this report is being prepared;
|
|
b)
|
designed

materially affect, the registrant’s internal control over
financial reporting; and
|

ability to record, process, summarize and report financial
information; and
|
|

|
Any
fraud, whether or not material, that involves management or other
employees who have a significant role in the registrant’s
