have:




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

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

internal control over financial reporting; and




5. The registrant's other certifying
officer and I have disclosed, based on our most recent evaluation of internal

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.
