American Century Investment Management, Inc. ("American Century") that

of conditions, including the separate approval of agreements and plans of
reorganization (the "Reorganization Agreements") by shareholders of the Funds at
a special shareholders meeting to be held on or about January 12, 2007 (the

will be reorganized into the American Century New Opportunities II Fund, a
series of American Century Mutual Funds, Inc., and the Kopp Total Quality

also be asked to approve a subadvisory agreement appointing American Century as
subadvisor to the Kopp Emerging Growth Fund for purposes of transitioning the
portfolio prior to the reorganization. This subadvisory arrangement, which has
been approved by the board of directors of Kopp Funds, will take effect
following shareholder approval of the reorganization and the subadvisory
agreement.
Additional details regarding the Special Meeting will be contained in a
