    a) designed such disclosure controls and procedures, or caused such
       disclosure controls and procedures to be designed under our

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

    b) designed such internal control over financial reporting, or caused such

       control over financial reporting that occurred during the registrant's
       most recent fiscal quarter (the registrant's fourth fiscal quarter in
       the case of an annual report) that has materially affected, or is
       reasonably likely to materially affect, the registrant's internal
       control over financial reporting; and

5.  The registrant's other certifying officer(s) and I have disclosed, based
    on  our most recent evaluation of internal control over financial
    reporting, to the registrant's auditors and the audit committee of the
    registrant's board of directors (or persons performing the equivalent
    functions):

    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.
