          2004;
 
 2.
          Based
          on my knowledge, the report does not contain any untrue statement of a
          material
          fact or omit to state a material fact necessary to make the statements
          made, in
          light of the circumstances under which such statements were made, not misleading

          Based
          on my knowledge, the financial statements, and other financial information
          included in this report, fairly present in all material respects the financial
          condition, results of operations and cash flows of the registrant as of,
          and
          for, the periods presented in this report;
 
 4.
          The
          registrant's other certifying officers and I am 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
          material information relating to the registrant, 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) Evaluated the effectiveness of the registrant's disclosure controls
          and
          procedures and presented in this report our conclusions about the effectiveness
          of the disclosure controls and procedures, as of the end of the period
          covered
          by this report based on such evaluation; and
 
 c) Disclosed in this report any change in the registrant’s internal 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 officers and I have disclosed, based on our
          most
          recent evaluation, to the registrant's auditors and the audit committee
          of
          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 controls which are reasonably likely to adversely
          affect
          the registrant’s ability to record, process, summarize and report financial
          information (all of which do not apply); 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
          (all
          of which do not apply).
