("the registrant");

2. Based on my knowledge, this report does not contain any untrue statement of a
material fact or omit to state a material fact  necessary to make the statements

misleading with respect to the period covered by this report;

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

4.  The  registrant's  other  certifying  officer  and  I  are  responsible  for
establishing and maintaining "disclosure controls and procedures" (as defined in

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

     b. designed such internal control over financial reporting,  or caused such

over financial  reporting that occurred  during the  registrant's  fourth fiscal
quarter 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 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  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  control over  financial  reporting  which are  reasonably
likely  to  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.
