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

3. Based on my knowledge, the financial statements, and other financial

reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) 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 material information relating
          to the registrant, including its consolidated subsidiaries, is

          during the period in which this report is being prepared;

          has materially affected, or is reasonably likely to materially
          affect, the registrant's internal control over financial
          reporting; and

registrant's board of directors (or persons performing the equivalent
functions):

     (a)  all significant deficiencies in the design or operation of internal
          controls which could adversely affect the registrant's ability to
          record, process, summarize and report financial data and have
          identified for the registrant's auditors any material weaknesses in
          internal controls; and

     (b)  any fraud, whether or not material, that involves management or other
          employees who have a significant role in the registrant's internal
          controls; and

Annual Report whether or not there were significant changes in internal controls
or in other factors that could significantly affect internal controls subsequent
to the date of our most recent evaluation, including any corrective actions with
regard to significant deficiencies and material weaknesses.
