                               CUSIP - 920-910-205

                        NOTICE OF PROPOSED REORGANIZATION



         NOTICE IS HEREBY GIVEN that VAN KAMPEN CALIFORNIA MUNICIPAL TRUST
("California Municipal Trust") is scheduled to reorganize into VAN KAMPEN
CALIFORNIA VALUE MUNICIPAL INCOME TRUST (the "Acquiring Fund") after the close
of business on December 2, 2005.

         The Acquiring Fund currently has three series of auction preferred
shares ("APS"). After the reorganization is completed, the Acquiring Fund will
have four series of APS: (i) the Acquiring Fund's existing APS will comprise
Series A APS, Series B APS and Series C APS and (ii) the Acquiring Fund will
issue a new series of APS ("Acquiring Fund Series D APS") in exchange for
California Municipal Trust's existing remarketed preferred shares ("California
Municipal Trust RP"). Two shares of Acquiring Fund Series D APS will be issued
in exchange for each share of California Municipal Trust RP, so that the
liquidation preference for Acquiring Fund Series D APS will be $25,000 per
share. The number of days in the regular dividend period for Acquiring Fund
Series D APS will remain the same as the existing California Municipal Trust RP
(i.e., an auction for Acquiring Fund Series D APS will occur every 28 days,
unless the Acquiring Fund declares a special dividend period).

         The previous remarketing for California Municipal Trust RP occurred on
November 8, 2005. On December 2, 2005, holders of California Municipal Trust RP
will receive i) a dividend representing the twenty-four day period from November
9, 2005 through December 2, 2005 and ii) two Acquiring Fund Series D APS in
exchange for each share of California Municipal Trust RP. The initial dividend
rate for the Acquiring Fund Series D APS will be the rate as determined at the
November 8, 2005 remarketing for California Municipal Trust RP, and this rate
will continue until the next regularly scheduled auction for Acquiring Fund
Series D APS, which is expected to be on December 6, 2005 (i.e., 28 days after
November 8, 2005).

         The foregoing does not constitute an offer of any securities for sale.
The joint proxy statement/prospectus relating to the proposed reorganization
contains important information and shareholders are urged to read it. Free

Kampen's Client Relations Department at (800) 341-2929 or on the Securities and
Exchange Commission's web site at www.sec.gov.
