On May 19, 1999, the name of the Fund's Distributor and Shareholder Service
Agent was changed from Oberweis Brokerage, Inc. to Oberweis.net, Inc. to
reflect new Internet stock brokerage execution services being offered by
Oberweis.net. The address and phone numbers remain the same.
Effective September 1, 1999, a feature of The Oberweis Funds' (the "Fund")
Exchange Privilege will be modified. The Fund's Exchange Privilege is
discussed in full on page 20 of the Fund's prospectus. As of September 1,
1999, the exchange privilege with Cash Resource Trust will no longer be
available. Beginning September 1, 1999, your Portfolio shares may be exchanged
for shares of three money market funds managed by State Street Bank and Trust
Company: SSgA Money Market Fund, SSgA U.S. Government Money Market Fund, and

portfolio of the SSgA Funds, an open-end management investment company
commonly referred to as a mutual fund with a series or multiple portfolios
advised by the State Street Bank and Trust Company, 225 Franklin Street,
Boston, MA, 02110. You may later then exchange such shares purchased and
