EXHIBIT 1
Proposal Submitted to the Fund

Investment Grade Municipal Income Fund
UBS Global Asset Management (Americas) Inc.

New York, New York 10019-6114

	Re:	Investment Grade Municipal Income Fund

Mr. Kemper:
Karpus Management, Inc., d/b/a Karpus Investment Management ("Karpus") represents beneficial ownership of 1,063,685 shares or 10.27% of the outstanding common shares of Investment Grade Municipal Income Fund ("PPM" or the "Fund").

Karpus intends to present the following proposal at the 2009 annual meeting, anticipated to be held in January 2009 (the "Meeting"):

PROPOSAL

    The investment advisory agreement between the Fund and UBS Global Asset Management shall be terminated.

    SUPPORTING STATEMENT

    As shareholders of PPM, we are concerned with the persistently wide discount to net asset value (NAV). As the prospectus states, "The Fund's board of directors has determined that it will from time to time consider taking action to attempt to reduce or eliminate any discount." Additionally, the Fund also specifically committed to at least annually consider: "...action either to repurchase shares of the common stock in the open market or to make a tender offer for shares of the common stock at their net asset value." Since the fund's inception in 1992, we cannot find any evidence that the Fund has repurchased any shares or considered making a tender offer for shares at NAV.

    The discount on PPM has consistently been among the widest of all closed-end municipal bond funds. Indeed, the 10-year average discount for PPM through 3/31/2008 was 10.96% while the average municipal closed-end fund discount was 3.89% during this same time period. (Source: Bloomberg). In addition to the promise to "consider tender offers or share repurchases, the prospectus states that the board of directors will "consider" converting the fund into an open-end fund so long as it is in the best interest of shareholders. To date, we have seen no evidence of this either, which makes it clear the board has no action plan to narrow the discount and enhancing shareholder value.

    The market tends to place a fair price on an asset -- in this case a share of a closed-end fund. Perhaps the explanation for why PPM has traded at such a persistently wide discount is that its NAV total return has been disappointing for a long period of time. For the trailing 10-year period (through 3/31/2008), our fund falls squarely in the bottom half for total return relative to other municipal closed-end funds over this period of time (Source: Bloomberg). This may be a result of the high expense ratio of 1.3% for the fund, which is higher than over 90% of all other municipal closed-end funds (Source: "Investors Guide to Closed-end Funds," Thomas J. Hertzfeld, July 2008). For the calendar year 2007, there were only two funds out of a universe of 262 closed-end municipal bond funds that had a wider average discount than PPM -- one of which was also a fund managed by UBS Global Asset Management. Clearly, the market does not have confidence in the management of the fund.

    The board of directors has a duty to monitor fund performance and should have been proactive in seeking a sub-advisor. It is unacceptable that they have allowed the fund to consistently perform below average and the discount to remain wide. To address these issues, we believe that a change to a new investment adviser is necessary. If the board of directors cannot recognize this and continues to do nothing, we will consider taking action to replace the board with directors whose interests better align with shareholders.

    END OF PROPOSAL

As is required by Rule 14a-8, KIM has attached a letter from U. S. Bank N.A., as well as a written statement from the "record" holder of the referenced shares, verifying that the referenced shares were continuously and beneficially owned, and had a market value of $2,000 or more, for at least a one year period prior to the date of the submittal of this Proposal. KIM intends to hold the shares referenced in the enclosed attachments through the date of the Meeting.

Please advise us immediately if this notice is deficient in any way or any additional information is required so that we may promptly provide it in order to cure any deficiency.

Sincerely,



Sharon L. Thornton
Senior Director of Investments
