SUBSCRIPTION PERIOD
American Century Investment Services, Inc. ("ACIS"), a distributor for the Life
Sciences Fund and Technology Fund (collectively, the "Funds"), will solicit
orders to purchase shares of the Funds during an initial offering period from
June 1, 2000, to June 29, 2000 (the "Subscription Period"). Orders received in
proper form during the Subscription Period will be accepted by the Funds at an
initial offering price of $5.00 per share on June 29, 2000. Payments
accompanying orders received during the Subscription Period will be held by the
Funds' transfer agent uncashed and uninvested until the Subscription Period
ends.
Charles Schwab & Co., Inc. ("Schwab") is also soliciting subscriptions of shares
of the Funds during the Subscription Period pursuant to a selected dealer
agreement with ACIS. The $5.00 per share purchase price for shares of the Funds
ordered through Schwab will be paid from a Schwab customer's brokerage account
on June 29, 2000. The funds to cover the subscription order must be available in
the Schwab account by the close of business on Monday, June 26, 2000, or the
order may be cancelled. ACIS or an affiliate will pay Schwab for its services
during the Subscription Period. All fees paid to Schwab for subscription
services will be paid by ACIS out of its own resources or those of its
affiliates and will have no effect on the Funds' fees or expenses. After the
Subscription Period, Schwab will receive service fees for recordkeeping and
shareholder servicing of Fund shares purchased through Schwab.
Shares of the Funds will not be offered to the public prior to the Funds'
commencement of operations except through these subscription offers.
