registrant and have:

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

ensure that material information relating to the registrant is made known to us
by others within those entities, particularly during the period in which this

and

         5. The registrant's other certifying officers and I have disclosed,

         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.
