Rules  13a-14  and  15d-14,  as  created  pursuant  to  Section  302(a)  of  the

         (1)  I have  reviewed  this  Quarterly  Report on Form 10-Q of the
              Company  for the three and six months  ended June 30, 2003 (the
              "Quarterly Report");

         (2)  Based on my knowledge,  this Quarterly 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  Quarterly
              Report;

         (3)  Based  on  my  knowledge,  the  financial  statements,  and  other

              periods presented in this Quarterly Report;

         (4)  The Company's other certifying  officers 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))  and
              internal control over financial  reporting (as defined in Exchange
              Act Rules 13a-15(f) and 15(d)-15(f)) for the Company and have:

                  (a) designed  such  disclosure  controls  and  procedures,  or
                      caused  such  disclosure  controls  and  procedures  to be
                      designed  un our  supervision,  to  ensure  that  material
                      information   relating  to  the  Company,   including  its
                      consolidated  subsidiaries,  is made known to us by others
                      within those entities,  particularly  during the period in
                      which this Quarterly Report is being prepared;

                  (b) designed such internal  control over financial  reporting,
                      or caused such internal  control over financial  reporting
                      to  be  designed   under  our   supervision,   to  provide
                      reasonable   assurance   regarding  the   reliability   of
                      financial  reporting  and  the  preparation  of  financial
                      statements  for  external   purposes  in  accordance  with
                      generally accepted accounting principles;

                  (c) evaluated the  effectiveness  of the Company's  disclosure
                      controls and  procedures  and presented in this  Quarterly
                      report  our  conclusions  about the  effectiveness  of the
                      disclosure  controls and procedures,  as of the end of the
                      period  covered  by this  Quarterly  report  based on such
                      evaluation; and

                  (d) disclosed  in this  Quarterly  report  any  change  in the
                      Company's  internal control over financial  reporting that
                      occurred during the Company's quarter ending June 30, 2003
                      that has materially  affected,  or is reasonable likely to
                      materially  affect,  the Company's  internal  control over
                      financial reporting; and

         (5)  The  Company's  other  certifying  officers and I have  disclosed,
              based on our most recent evaluation, to the Company's auditors and
              the  audit  committee  of the  Company'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 Company'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   Company's   internal   control  over   financial
                      reporting.
