2. Based on my knowledge, this annual report does not contain any untrue

were made, not misleading with respect to the period covered by this annual

respects the financial condition, results of operations and cash flows of the
registrant as of, and for, the periods presented in this annual report;

4. The registrant's other certifying officers and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and have:

a)   designed such disclosure controls and procedures or caused such disclosure
     controls and procedures to be designed under our supervision to ensure that

     subsidiaries, is made known to us by others within those entities,
     particularly during the period in which this annual report is being
     prepared;

b)   evaluated the effectiveness of the registrant's disclosure controls and
     procedures and presented in this annual report our conclusions about the
     effectiveness of the disclosure controls and procedures as of the end of

     recent fiscal year 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 officers 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 function):

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.
