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

4.   The  registrant's  other  certifying  officer(s)  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
          me  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  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  registrant's  disclosure
          controls  and  procedures and presented in this report our 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

     d)   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(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.
