    The Companys other certifying officer(s) and I are responsible for establishing and

    Designed such disclosure controls and procedures, or caused such disclosure

information relating to the Company, 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.

    Any fraud, whether or not material, that involves management or other employees
who have a significant role in the Companys internal control over financial reporting.
