Shares were sold through small lots which are reported as individual sales on this form and on other Form 4's being filed simultaneously because the EDGAR system will only accept 30 transactions on a single form.
(2)	Shares held as of 01/31/2006 in a multi-fund 401(k) Plan to be settled in cash upon the reporting person's termination of employment for any reason on a 1:1 basis.
