Kemper, Secretary Insured Municipal Income Fund Inc. UBS Global Asset Management 51 West 52nd Street New York, New York 10019-6114. Insured Municipal Income Fund Inc. (the Fund) Dear Mr. Kemper: On December 10, 2008 we sent you a rule 14a-8 proposal. In addition, on the same day, our affiliate, Bulldog Investors General Partnership (BIGP), sent you an advance notice letter of its intent to present nominees at the Funds next annual meeting. On December 15, 2008 both of these letters were filed on EDGAR. On Friday, January 23, 2009 Julien Bourgeois of Dechert informed me that you had not received the letters. In addition, Mr. Bourgeois advised us of what he asserted were certain omissions in our letters. We do not agree that our previous correspondence was deficient. However, in order to avoid any dispute about our right to present our proposal or our nominees, we are (1) enclosing another copy of our December 10, 2008 letter submitting our rule 14a-8 proposal, and (2) submitting this letter to provide you with advance notice of our intent to present nominations at the annual meeting. Since the nominations will be made by Full Value Offshore Partners (FVOP), I, as a principal of the managing general partner of BIGP, hereby withdraw BIGPs precious notice in lieu of this superseding notice. (Note that this letter also updates information about our nominees stock ownership and background.) In addition, we are enclosing documentation from our stock broker certifying that FVOP has owned more than $2,000 worth of the Funds common stock continuously since at least December 10, 2007. Finally, we affirm that we intend to appear in person or by proxy at the Funds annual meeting to present our proposal and nominees. If the Fund is still in existence at the next meeting of shareholders, we intend to nominate a full slate of candidates for election as directors. FVOP, the nominating and proposing shareholder, beneficially owns 43,589 common shares of the Fund. Assuming six directors are to be elected, we will nominate the persons named below. (Please advise us if a different number of directors will be elected.) Each nominee has consented to being named in our proxy statement and to serve as a director if elected. Messrs. Goodstein and Samuels are the nominees for the seats that will be elected solely by shareholders of the preferred stock. There are no arrangements or understandings between FVOP (or its affiliates) 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.
