         The enclosed proxy, which was first mailed on or about April 21, 2000,
is solicited by the Trustees of the above-listed funds (Funds) for use at the
Meetings. All properly executed proxies received in time for the Meetings will
be voted as specified in the proxy or, if no specification is made, in favor of
each proposal referred to in the Proxy Statement. The proxy may be revoked prior
to its exercise by a later dated proxy, by written revocation received by the
Secretary or by voting in person.

         Solicitation of proxies may be made by mail, telephone, telegraph,
telecopy and personal interviews. Authorization to execute proxies may be
obtained by telephonically or electronically transmitted instructions. The Funds

mailings.

         Votes cast by proxy or in person at any Meeting will be counted by
persons appointed by the Fund to act as election tellers for the Meeting. The
tellers will count the total number of votes cast "for" approval of the
proposals for purposes of determining whether sufficient affirmative votes have
been cast. Where a shareholder withholds authority or abstains, or the proxy
reflects a "broker non-vote" (i.e., shares held by brokers or nominees as to
which (i) instructions have not been received from the beneficial owners or
persons entitled to vote and (ii) the broker or nominee does not have
discretionary voting power on a particular matter) the shares will be counted as
present and entitled to vote for purposes of determining the presence of a
quorum. With respect to the election of Trustees and ratification of independent
accountants, withheld authority, abstentions and broker non-votes have no effect
on the outcome of the voting.

         Further information concerning each Fund is contained in its most
recent Annual Report to shareholders, which is obtainable free of charge by

3.    OTHER MATTERS AND DISCRETION OF PROXY HOLDERS NAMED IN THE PROXY.

         As of the date of this Proxy Statement, only the business mentioned in
Proposals 1 and 2 of the Notice of the Meetings is contemplated to be presented.
If any procedural or other matters properly come before any one or more of the
Meetings, the enclosed proxy (or proxies, as applicable) shall be voted in
accordance with the best judgment of the proxy holder(s).

         The Meetings are to be held simultaneously. In the event that any Fund
shareholder at a Meeting objects to the holding of simultaneous Meetings and
moves for an adjournment of the Meeting so that the Meeting of the Fund may be
held separately, the persons named as proxies will vote in favor of such an
adjournment.

         If a quorum of shareholders is not represented at a Meeting or at any
adjournment thereof, or, even though a quorum is so represented, if sufficient
votes in favor of the Proposals set forth in the Notice of the Meetings are not
received by May 24, 2000, the persons named as proxies may propose one or more
adjournments of the Meeting for a period or periods of not more than ninety days
in the aggregate and further solicitation of proxies may be made. Any such
adjournment may be effected by a majority of the votes properly cast in person
or by proxy on the question at the session of the Meeting to be adjourned. The
persons named as proxies will vote in favor of such adjournment those proxies
which they are entitled to vote in favor of the Proposals set forth in the
Notice of the Meetings. They will vote against any such adjournment those
proxies required to be voted against any of such Proposals.

                      COMPLIANCE WITH SECTION 16(a) OF THE
                         SECURITIES EXCHANGE ACT OF 1934

         Section 16(a) of the Securities Exchange Act of 1934, as amended, and
Section 30(f) of the Investment Company Act of 1940, as amended, require the
Board of Trustees and executive officers of any Fund, persons who own more than
ten percent of any Fund's equity securities (Section 16 reporting persons), the
Fund's investment advisor and affiliated persons of the Fund's investment
advisor to file with the Securities and Exchange Commission (SEC) initial
reports of ownership and reports of changes in ownership of the Fund's shares
and to furnish the Fund with copies of all Section 16(a) forms they file. Based
solely upon a review of copies of such reports furnished to the Funds, the Funds

                                       15



believe that all of the Trustees and Executive Officers of Colonial California
Insured Municipal Fund and Colonial Insured Municipal Fund filed late Forms 3
(Initial Statements of Beneficial Ownership), on which they reported no
holdings.
