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 his

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

      4. 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  subsidiary  is made known to us by others  within those  entities,
particularly during the period in which this quarterly report is being prepared;

      b. Evaluated the effectiveness of the registrant's disclosure controls and

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

      5. I have  disclosed,  based on our most  recent  evaluation  of  internal
control  over  financial  reporting,   to  the  registrant's  auditors  and  the
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 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.
