AUTOMATED CASH MANAGEMENT TRUST
(A Portfolio of Money Market Obligations Trust)
Cash II Shares
Institutional Service Shares
Supplement to Prospectuses dated September 30, 1997
At the April 23, 1998 shareholder meeting, shareholders approved a change to the
Fund's fundamental policy of investing in restricted securities. The policy is
now non-fundamental and allows the Fund to invest, without limitation, in
restricted securities which meet the Board of Trustees' guidelines for
liquidity. Therefore, the Fund's policy on restricted securities is as follows:
"The Fund may invest in restricted securities. Restricted securities
are any securities in which the Fund may invest pursuant to its
investment objective and policies but which are subject to
restrictions on resale under federal securities law. Under criteria
established by the Trustees, certain restricted securities are
determined to be liquid. To the extent that restricted securities
are not determined to be liquid the Fund will limit their purchase,
together with other illiquid securities, to 10% of its net assets."
