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 made, in light of the circumstances under which such statements
      were made,  not  misleading  with  respect  to the period  covered by this

3.    Based on my  knowledge,  the  financial  statements,  and other  financial
      information  included  in this  report,  fairly  present  in all  material

      the registrant as of, and for, the periods presented in this report;

4.    The  registrant's  other  certifying  officer(s) 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

            evaluation; and

      (c)   Disclosed  in this  report any change in the  registrant's  internal
            control  over   financial   reporting   that  occurred   during  the
            registrant's  most recent fiscal  quarter (the  registrant's  fourth
            fiscal  quarter  in the  case  of an  report)  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(s) 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.
