Mr. Richard Q. Armstrong UBS Funds
c/o Willkie Farr & Gallagher LLP
787 Seventh Avenue
New York, NY 10019.

Insured Municipal Income Fund Inc.

Dear Mr. Armstrong:

Please bring this letter to the attention of the board of directors.

Bulldog Investors is a group of private investment funds that have significant

investments in the Fund?s common stock.

As the board is undoubtedly aware, recent

events have adversely affected the liquidity of auction preferred shares "APS"

issued by closed-end funds in general and the Fund?s

APS in particular.  Although we are not owners

of the Fund?s APS, we are sympathetic to their plight.

Nevertheless, we believe it would be inappropriate for the

Fund to bail out the APS shareholders who,like the common shareholders,

are getting everything they are contractually entitled to receive.

Thus, we caution the board to eschew any action that would have

the appearance of benefitting shareholders of the APS at the expense

of the common stockholders or of the Fund as a whole. We are concerned

about the persistent discount to net asset value at which the Fund?s

common shares have been trading.  We believe that the board should

consider implementing measures designed to close that gap, including

open-ending the Fund.  Whatever the board?s views on

open-ending have been in the past, the world of leveraged

closed-end funds is now dramatically different.

It is now absolutely clear that

open-ending or liquidation of the Fund would provide a

benefit to both the common and the APS shareholders.

In any event, to insure that any action contemplated by the board

to benefit the APS shareholders is equitable to all

classes of the Fund?s shares, we strongly recommend that

such action be put to a shareholder vote.

Please contact us if the board would like to discuss this

matter further.

Very truly yours,


Phillip Goldstein

Principal
