     4.     The  registrant's other certifying officers and I am 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

     6.     The  registrant's  other certifying officers and I have indicated in
this  annual  report  whether  or not there were significant changes in internal
controls  or  in other factors that could significantly affect internal controls
