Designed such disclosure
  controls and procedures, or caused such disclosure controls and procedures to

  relating to the registrant, including its consolidated subsidiaries, is made
  known to us by others within those entities, particularly during the period
  in which this report is being prepared;(b)

  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)

  whether or not material, that involves management or other employees who have
  a significant role in the registrants internal control over financial
  reporting.  Date: June
