PRELIMINARY (SUBJECT TO CHANGE) PROXY STATEMENT OF BULLDOG INVESTORS GENERAL
PARTNERSHIP IN OPPOSITION TO THE SOLICITATION BY THE BOARD OF DIRECTORS OF
INSURED MUNICIPAL INCOME FUND INC. AT THE ANNUAL MEETING OF SHAREHOLDERS

Bulldog Investors General Partnership ("BIGP") is sending this proxy statement
and the enclosed GREEN proxy card to stockholders of Insured Municipal Income
Fund Inc. (the "Fund") of record as of May 15, 2009.  We are soliciting a proxy
to vote your shares at the Annual Meeting of Shareholders (the "Meeting") which
is scheduled for August 12, 2009.  Please refer to the Fund's proxy soliciting
material for additional information concerning the Meeting and the matters to
be considered by shareholders including the election of Directors. This proxy
statement and the enclosed GREEN proxy card are first being sent to
shareholders on or about May --, 2009.

INTRODUCTION

The Fund has announced that five matters will be voted upon at the Meeting:
(1) the election of six directors, (2) a proposal to approve a new investment
advisory and administration agreement between the Fund and UBS Global Asset
Management (Americas) Inc. ("UBS"); (3) a proposal to change an investment
policy; (4) a shareholder proposal requesting that the board take action,
subject to market conditions, to afford common and preferred shareholders an
opportunity to realize the net asset value of their shares; and (5) a
shareholder proposal that the investment advisory agreement between the Fund
and UBS be terminated. We are soliciting a proxy to vote your shares (1) FOR
the election of the six nominees named below as directors, (2) AGAINST proposals
2 and 3, and (2) FOR the proposals 4 and 5.

REASONS FOR THE SOLICITATION
The Fund's common shares have long traded at a discount to net asset value.
In addition, shareholders of the Fund's auction preferred shares ("APS") are
suffering from illiquidity as a result of the breakdown of the auction
mechanism. We believe both classes of shareholders deserve an opportunity to
realize the full value of their investment.  Consequently, we are seeking to
elect directors that will take action, subject to market conditions, to afford
common and preferred shareholders an opportunity to realize the intrinsic
value of their shares.

HOW PROXIES WILL BE VOTED
If you complete and return a GREEN proxy card to us and, unless you direct
otherwise, your shares will be voted FOR the election of the nominees named
below, AGAINST proposals 2 and 3, and FOR proposals 4 and 5.  In addition,
you will be granting the proxy holders discretionary authority to vote on any
other matters that may come before the Meeting.

VOTING REQUIREMENTS

A quorum is a majority of the total shares outstanding.  In addition, for the
election of the two directors to be elected solely by the Fund's APS, a quorum
is a majority of the APS outstanding. A plurality of the votes cast is
sufficient to elect a director.  The common and APS shareholders voting
together will elect four directors and the APS shareholders voting separately
will elect two directors.  Approval of proposals 2 and 3 and 5 require the
affirmative vote of shareholders owning the lesser of (a) 67 percent or more
of the shares present at the Meeting, or (b) more than 50 percent of the
Fund's outstanding shares. Approval of proposal 4 requires the affirmative
vote of a majority of the votes cast by all shareholders represented at the
Meeting.  An abstention or a broker non-vote will have the same effect as a
vote against proposals 2, 3 and 5 and will be ignored in determining the
votes cast for or against proposal 4. Since this is a contested solicitation,
we do not expect any broker non-votes.

REVOCATION OF PROXIES
You may revoke any proxy prior to its exercise by: (i) delivering a written
revocation to us; (ii) executing and delivering a later dated proxy; or
(iii) voting in person at the Meeting.  Attendance at the Meeting will not
in and of itself revoke a proxy.  There is no limit on the number of times
you may revoke your proxy before it is exercised.  Only your latest dated
proxy will be counted.

PROPOSAL 1: ELECTION OF DIRECTORS

At the Meeting, our affiliate intends to nominate the six persons named below
for election as Directors.  Each nominee has consented to being named in this
proxy statement and to serve as a Director if elected.  Messrs. Goodstein and
Samuels are the nominees for the seats to be elected solely by shareholders of
the APS.  There are no arrangements or understandings between BIGP or any
affiliate of BIGP and any nominee in connection with the nominations nor do we
know of any material conflicts of interest that would prevent any nominee from
acting in the best interest of the Fund.  Please refer to the Fund's proxy
soliciting material for additional information concerning the election of
Directors.

THE SOLICITATION

Persons affiliated with or employed by BIGP or its affiliates may assist us
in the solicitation of proxies.  Banks, brokerage houses and other custodians,
nominees and fiduciaries will be requested to forward this proxy statement
and the enclosed GREEN proxy card to the beneficial owners of common and
preferred shares for whom they hold shares of record. We will reimburse these
organizations for their reasonable out-of-pocket expenses.

Initially, we will bear all of the expenses related to this proxy solicitation.
Because we believe that all shareholders will benefit from this solicitation,
we intend to seek, subject to any applicable regulatory requirements,
reimbursement of our expenses as well as last year's expenses from the Fund.
Shareholders will not be asked to vote on the reimbursement of these expenses,
which we estimate will total $100,000.

PARTICIPANTS

BIGP is the soliciting stockholder and beneficially owns ---------- common
shares.  In addition, affiliates of BIGP beneficially own ----------- common
shares.   Phillip Goldstein beneficially owns jointly with his wife -------
common shares and Rajeev Das beneficially owns ---- common shares. Clients of
Glenn Goodstein beneficially own ------- common shares.  Each of Messrs.
Goldstein and Das, Dakos and Samuels is a principal of one or more funds in
the Bulldog Investors group of funds, some of which are partners in BIGP.
The address of each of the aforementioned persons and entities is Park 80 West,
Plaza Two, Suite 750, Saddle Brook, NJ 07663.  Other clients advised by Messrs.
Goldstein and Dakos own a total of ------------ common shares.  All of the
shares owned by the aforementioned persons and entities were acquired
between --------------- and ------------------.

The staff of the SEC deems each person and entity named in this section
including each fund in the Bulldog Investors group of private investment funds
to be a "participant" in this solicitation.  Only BIGP and Messrs. Goldstein
and Dakos are actively engaged in this solicitation.  The role of Messrs.
Hellerman, Das, Goodstein and Samuels in this solicitation is limited to
providing biographical information.  The SEC deems a nominee to be a
"participant" in a proxy solicitation which may be misleading because it
suggests that the nominee has a greater role in the solicitation than may
be the case.   Nevertheless, using the SEC's definition of "participant,"
no participant or associate of any participant in this solicitation is or
has been a party to any contract, arrangements or understanding with any
person with respect to any securities of the Fund or has any arrangement or
understanding with any person with respect to future employment by the Fund
or any of its affiliates or to any future transactions to which the Fund or
any of its affiliates will or may be a party.

UNRELATED LITIGATION
On January 31, 2007, the Acting Director of the Securities Division of the
Massachusetts Secretary of State (the "Secretary") filed a complaint against
Opportunity Partners L.P., Messrs. Goldstein, Dakos and Das and Samuels and
certain related parties (the "Bulldog Parties") alleging that they violated
Massachusetts law by making information about certain unregistered securities
available on the Bulldog Investors website and by providing information about
such investments to an individual who requested it without first determining
that the individual was eligible to invest in such securities. On October 17,
2007, the Secretary issued a cease and desist order and imposed a fine of
$25,000 on the Bulldog Parties.  The Bulldog Parties appealed the Secretary's
ruling to Massachusetts Superior Court which upheld the Secretary's order.
The Bulldog Parties have filed a further appeal with the Appellate Court of
Massachusetts.  That appeal may be consolidated with the appeal of a lawsuit
filed on March 23, 2007 by the Bulldog Parties in Massachusetts Superior Court
to enjoin the Secretary's enforcement action.
