material fact or omit to state a material fact  necessary to make the statements

misleading with respect to the period covered by 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  period in which  this  report is being
     prepared; and

     b) Designed such internal control over financial reporting,  or caused such
     internal  control  over  financial  reporting  to  be  designed  under  our
     supervision,   to  ensure  that  material   information   relating  to  the

     others within those entities,  particularly during the period in which this
     report is being prepared; 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.

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 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.
