    The Registrants other certifying officers and I have disclosed, based on
our most recent evaluation of internal control over financial reporting,

of directors (and persons performing the equivalent function):  (a)
    
    all significant deficiencies and material weaknesses in the

information and have identified for the Registrants auditors any
material weaknesses in internal controls; and(b)

or other employees who have a significant role in the registrants
internal controls.  6.

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. Date: May 17, 2004
