establishing  and  maintaining disclosure controls and procedures (as defined in

a)  designed  such  disclosure  controls  and procedures to ensure that material

period  in  which  this  quarterly  report  is  being  prepared;

auditors  any  material  weaknesses  in  internal  controls;  and

b)  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
quarterly  report  whether  or  not  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.
