a)
designed such disclosure controls and			procedures, or caused such disclosure controls and procedures to be			designed under our supervision, 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 report is being prepared;
 
b)
not applicable

disclosed in the report any change in the			registrant's internal control over financial reporting that occurred			during the registrant's first quarter that has materially affected,			or is reasonably likely to materially affect, the registrant's			internal control over financial reporting; and
			     5.     The registrant's other certifying officer and I have			disclosed, based on our most recent evaluation of internal control			over financial reporting, to the registrant's auditors and the audit			committee of registrant's board of directors (or persons performing			the equivalent functions):
			     a)     all significant deficiencies and material weaknesses in			the design or operation of internal control over financial reporting			which are reasonably likely to adversely affect the registrant's			ability to record, process, summarize and report financial			information; and 
			     b)     any fraud, whether or not material, that involves			management or other employees who have a significant role in the			registrant's internal control over financial reporting.
