Corporation;

2. Based on my knowledge, this report does not contain any untrue statement of a

registrant and have:

 a. Designed such disclosure controls and procedures, or caused such
    disclosure controls and procedures to be designed under our supervision,

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

 b. Designed such internal control over financial reporting, or caused such

         financial reporting; and

5. The registrant's other certifying officer and I have disclosed, based on our

    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.
