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 report;

3.       Based on my knowledge,  the financial  statements,  and other financial
         information  included in this  report,  fairly  present in all material
         respects the financial condition,  results of operations and cash flows
         of the registrant as of, and for, the periods presented in this report;

4.       The  registrant's  other  certifying  officer 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
              period in which this report is being prepared;

              conclusions about the effectiveness of the disclosure controls and
              procedures,  as of the end of the period  covered  by this  report
              based on such 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  annual  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 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.
