quarterly report is being prepared;
|--- |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(a) |  | all
significant deficiencies in the design or operation of internal controls which could
adversely          affect the Registrant's ability to record, process, summarize and

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.
|--- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------

|6. | The
Registrant's  other  certifying  officers and I have indicated in this quarterly report
