        Corporation;


     2. Based on my  knowledge,  this annual  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

     3. Based on my knowledge,  the financial  statements,  and other  financial
        information  included  in this  annual  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 annual report;


     4. The  registrant's  other  certifying  officers and I are responsible for
        establishing  and  maintaining  disclosure  controls and  procedures (as
        defined in Exchange Act Rules 13a-14 and 15d-14) for the  registrant and
        have:

a.                designed  such  disclosure  controls and  procedures 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 annual report is being prepared;

b.                evaluated the  effectiveness  of the  registrant's  disclosure
                  controls and  procedures  as of a date within 90 days prior to
                  the filing date of this annual report (the "Evaluation Date");
                  and

c.                presented  in this  annual  report our  conclusions  about the
                  effectiveness of the disclosure  controls and procedures based
                  on our evaluation as of the Evaluation Date;


     5. The registrant's other certifying  officers and I have disclosed,  based
        on our most recent  evaluation,  to the  registrant's  auditors  and the
        audit  committee  of   registrant's   board  of  directors  (or  persons
        performing the equivalent functions):

d.                all  significant  deficiencies  in the design or  operation of
                  internal   controls   which   could   adversely   affect   the
                  registrant's ability to record, process,  summarize and report
                  financial  data  and  have  identified  for  the  registrant's
                  auditors any material weaknesses in internal controls; and

e.                any fraud,  whether or not material,  that involves management
                  or  other  employees  who  have  a  significant  role  in  the
                  registrant's internal controls; and


     6. The registrant's other certifying  officers and I have indicated in this
        annual  report  whether  there  were  significant  changes  in  internal
        controls or in other factors that could  significantly  affect  internal
        controls subsequent to the date of our most recent evaluation, including
        any  corrective  actions  with regard to  significant  deficiencies  and
        material weaknesses.
