        DELAWARE INVESTMENTS MUNICIPAL INCOME FUNDS ANNOUNCE ELECTION OF
            PATRICK P. COYNE AS PRESIDENT AND CHIEF EXECUTIVE OFFICER
               OF THE FUNDS AND ADDITIONAL INFORMATION RELATED TO
                          THEIR UPCOMING ANNUAL MEETING

PHILADELPHIA, AUGUST 1, 2006 - Delaware Investments Arizona Municipal Income
Fund, Inc. (ASE:VAZ), Delaware Investments Colorado Insured Municipal Income
Fund, Inc. (ASE:VCF), Delaware Investments Florida Insured Municipal Income Fund
(ASE:VFL) and Delaware Investments Minnesota Municipal Income Fund II, Inc.
(ASE:VMM), all closed-end investment management companies (each, a "Fund"),
today announced that the Funds' Board of Directors/Trustees (the "Board") has
elected Patrick P. Coyne as president and chief executive officer of each Fund,
effective August 1, 2006. Mr. Coyne has been with Delaware Investments, the
parent company of the Fund's investment manager, for more than 17 years and is
currently the firm's president. Mr. Coyne is also president and chief executive
officer of all funds in the Delaware Investments(R) Family of Funds. The team
responsible for managing each Fund's assets remains in its role at Delaware
Investments.

The Funds also announced additional information related to their upcoming Annual
Meeting of Shareholders (the "Meeting"). A Combined Proxy Statement dated July
10, 2006 (the "Proxy Statement") related to the Meeting was mailed to each
Fund's shareholders on or about July 12, 2006. The sole proposal to be presented
to shareholders at the Meeting is the election of the Board. Subsequent to the
mailing of the proxy materials, Jude T. Driscoll, a Director/Trustee and one of
the nominees for election to the Board, resigned from the Board, effective
August 1, 2006. As a result, Mr. Driscoll has withdrawn from the election
described in the Proxy Statement, and any votes received with respect to Mr.
Driscoll will therefore not be counted.

At a regularly scheduled meeting on August 16, 2006, the Board's Nominating
Committee is expected to recommend substituting Patrick P. Coyne for Mr.
Driscoll as a nominee for election to the Board and, if Mr. Coyne is recommended
by the Nominating Committee, the Board is expected to recommend Mr. Coyne as a
substitute nominee for election to the Board. As previously disclosed in the
Proxy Statement, in the case of the withdrawal of a nominee for election, the
power given by shareholders in the Proxy Card may be used by the persons named
as proxies to vote for a substitute nominee or nominees as recommended by the
existing Board. Accordingly, if Mr. Coyne is recommended by the Board as a
substitute nominee, the named proxies are expected to exercise their discretion
to vote for Mr. Coyne at the Meeting.


The investment objective of each Fund is to provide current income exempt from
federal income tax and from the personal income tax of its state, if any,
consistent with the preservation of capital. In addition, each Fund utilizes
leveraging techniques in an attempt to obtain a higher return for the Fund.
