establishing and maintaining  disclosure  controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and we 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, 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

reporting; and

directors (or persons performing the equivalent function):

         (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
controls over financial reporting.
