     1.) I have reviewed this annual report on Form 10-K of the registrant;

     2.) Based on my knowledge, this annual 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 with respect to the period covered by
     this annual report;

     4.) The registrant's other certifying officer 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 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 annual report is being prepared;

          b.) evaluated the effectiveness of the registrant's disclosure
          controls and procedures 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 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.

     5.) The registrant's other certifying officer 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 board of
     directors (or persons fulfilling 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 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.
