Tax-Exempt California Money Market Fund


At present, substantially all DWS mutual funds are overseen by one of two
clusters of boards of trustees/directors (the "Boards").  Each Board, including
the Board that oversees your Fund (the "Chicago Board"), has determined that
the formation of a single consolidated Board overseeing substantially all DWS
mutual funds is in the best interests of the Funds.  In this connection, each
Board has approved a plan outlining the process for implementing the
consolidation of the Chicago Board with the other primary DWS mutual fund board
(the "New York Board").  (The geographic references in the preceding sentences
merely indicate where each Board historically held most of its meetings.)

The consolidation of the two Boards is expected to take effect on or about
April 1, 2008 (the "Consolidation Date").  To accomplish the consolidation, the
Chicago Board has determined to nominate and recommend that shareholders of
each Fund re-elect four members of your Fund's Board (John W. Ballantine, Paul
K. Freeman, William McClayton and Robert H. Wadsworth, collectively, the
"Chicago Nominees") and elect eight individuals who  currently serve on the New
York Board (Henry P. Becton, Jr., Dawn-Marie Driscoll, Keith R. Fox, Kenneth C.
Froewiss, Richard J. Herring, Rebecca W. Rimel, William N. Searcy, Jr. and Jean
Gleason Stromberg, collectively, the "New York Nominees") to the Board of your
Fund.  Information regarding the New York Nominees is set forth below.  In
addition, the New York Board will nominate and elect the Chicago Nominees to
the Board of each fund currently overseen by the New York Board.  As a result,
as of the Consolidation Date, it is expected that the twelve individuals named
in this paragraph (each of which will be considered non-interested), together
with Axel Schwarzer, CEO of DWS Scudder, will constitute the Board of each DWS
mutual fund (134 funds), including your Fund.

To facilitate the Board consolidation, four members of the Chicago Board
(Donald L. Dunaway, James R. Edgar, Robert B. Hoffman and Shirley D. Peterson)
have agreed not to stand for re-election (the "Non-Continuing Board Members").
Independent members of the Chicago Board are not entitled to benefits under any
pension or retirement plan.  However, the Chicago Board determined that it
would be appropriate to provide the Non-Continuing Board Members with a
retirement agreement, the terms of

<PAGE>

which include a one-time retirement payment. For each Non-Continuing Board
Member, the amount of the retirement payment is based on the product of (i) such
individual's current annual Board member compensation times (ii) the lesser of
five years or the number of years (and/or portion thereof) from the expected
Consolidation Date to the date when such individual would reach the Funds'
mandatory retirement age. As Deutsche Investment Management Americas Inc.
("DIMA"), the Funds' investment adviser, will also benefit from the
administrative efficiencies of a consolidated Board, DIMA has agreed to
reimburse the Funds for the cost of the retirement payments. The amount to be
received by each Non-Continuing Board Member is as follows: $354,375 in the
aggregate for all the Funds (between $64 and $68,321 per Fund) for Mr. Dunaway;
$950,000 in the aggregate for all the Funds (between $172 and $183,153 per Fund)
for Mr. Edgar; $138,750 in the aggregate for all the Funds (between $25 and
$26,750 per Fund); for Mr. Hoffman; and $937,500 in the aggregate for all the
Funds (between $170 and $180,743 per Fund) for Ms. Peterson. In connection with
the receipt of the retirement payment, each Non-Continuing Board Member agreed
that, without the prior written consent of the DWS funds, he or she shall not in
any way, directly or indirectly, solicit, accept, or serve in any position as a
director, trustee, or equivalent role on the Board of any investment company
registered with the SEC for a specified period.

In addition, pursuant to the retirement agreement and a separate agreement
between the Funds and DIMA, each Non-Continuing Board Member has received
certain assurances from the Funds and DIMA regarding continuation of insurance
and indemnification rights.  With respect to insurance, for the six-year period
following the Consolidation Date, the Funds currently expect to maintain,
D&O/E&O Insurance and Independent Director Liability ("IDL") Insurance that is
substantially equivalent in scope to the current coverage, and in amounts
providing aggregate coverage with respect to the Funds and all funds overseen
by the consolidated Board of at least $100 million for D&O/E&O Insurance and at
least $25 million for IDL Insurance.  With respect to indemnification, the
Funds have provided assurances that the retirement agreement, the retirement of
the Non-Continuing Board Member and/or the election or appointment of members
of the consolidated Board shall not reduce or impair any rights of the
Non-Continuing Board Member to indemnification, defense, advancement of
expenses, or other rights, for or with respect to actual or threatened claims,
liability, or expense that the Non-Continuing Board Member may incur or suffer
arising from or with respect to the Non-Continuing Board Member's service in
such capacity.

DIMA has similarly agreed that the retirement of the Non-Continuing Board
Members under the terms of the retirement agreements shall in no way affect or
diminish the contractual rights of indemnification that the Non-Continuing
Board Members may have under any agreement of indemnification between a
Non-Continuing Board Member and DIMA.

In addition, in the event that the consolidated Board determines to reduce
insurance coverage below the minimum levels stated above, then DIMA at its
expense will purchase excess insurance coverage for the benefit of the
Non-Continuing Board Members sufficient to maintain such minimum coverage
levels in place for the duration of the period specified in the retirement
agreements, provided that in the event that such excess coverage is not
available in the marketplace on commercially reasonable terms from a
conventional third-party insurer, DIMA (or an affiliate of DIMA) may, at DIMA's
discretion and in lieu of purchasing such excess insurance coverage, elect
instead to provide the Non-Continuing Board Members substantially equivalent
protection in the form of a written indemnity or financial guaranty reasonably
acceptable to each such Non-Continuing Board Member.

Following the Consolidation Date, it is expected that the consolidated Board
will implement certain changes to the Funds' current committee structure and
other governance practices, including the appointment of new committee chairs
and members.  Additional information regarding these changes will be set forth
in each Fund's statement of additional information upon implementation.
