        a
        material fact or omit to state a material fact necessary to make the statements

        maintaining disclosure controls and procedures (as defined in Exchange Act

 d)
              designed
                  such disclosure controls and procedures to ensure that material
                  information relating to the Company, 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;
 e)
              evaluated
                  the effectiveness of the Company’s disclosure controls and procedures as
                  of a date within 90 days prior to the filing date of this annual
                  report
                  (the “Evaluation Date”); and
 f)
              presented
                  in this annual report our conclusions about the effectiveness of
                  the
                  disclosure controls and procedures based on our evaluation as of
                  the
                  Evaluation Date;
 
 5.  The
        Company’s other certifying officers and I have disclosed, based on our most
        recent evaluation, to the Company’s auditors and the audit committee of
        Company’s board of directors (or persons performing the equivalent
        function):
 
 c)
              all
                  significant deficiencies in the design or operation of internal
                  controls
                  which could adversely affect the Company’s ability to record, process,
                  summarize and report financial data and have identified for the
                  Company’s
                  auditors any material weaknesses in internal control;
                  and
 d)
              any
                  fraud, whether or not material, that involves management or other
                  employees who have a significant role in the Company’s internal controls;
                  and
 
 6.  The
        Company’s other certifying officers and I have indicated in this 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
