DEAR SHAREHOLDER:

We are pleased to invite you to the Annual Meetings of Shareholders of each of Nuveen Performance Plus Municipal Fund, Inc., Nuveen Municipal Advantage Fund, Inc., Nuveen Investment Quality Municipal Fund, Inc., Nuveen Insured Quality Municipal Fund, Inc., Nuveen Select Quality Municipal Fund, Inc., Nuveen Quality Income Municipal Fund, Inc., and Nuveen Insured Municipal Opportunity Fund, Inc. The meetings are scheduled for Thursday, July 25, 1996 at 10:30 a.m., Chicago time, in the 6th floor auditorium of The Northern Trust Company, 50 South LaSalle Street, Chicago, Illinois.

At the Annual Meetings, all shareholders will be asked to consider and approve a very important proposal. The Funds' management seeks to update the terms of the Money Market Cumulative Preferred Stock or Municipal Auction Rate Cumulative Preferred Stock, as the case may be, (MuniPreferred(R)) to conform with the state-of-the-art terms of more recent MuniPreferred offerings (as more fully described in the attached proxy statement). We believe the proposals will provide a wider range of investment choices and simplify investing in and owning shares of MuniPreferred, potentially making MuniPreferred an even better investment. If approved, the terms of the MuniPreferred would be amended to, among other things, offer the following advantages:

- Eliminate Master Purchaser's Letters

- Refine Maximum Dividend Rate Provisions

- Increase Flexibility in Establishing Extended Rate Periods

You will also be asked to elect directors and ratify the selection of independent auditors.

WHETHER OR NOT YOU PLAN TO JOIN US, PLEASE COMPLETE, DATE AND SIGN YOUR PROXY CARD AND RETURN IT IN THE ENCLOSED ENVELOPE SO THAT YOUR VOTE WILL BE COUNTED.

We appreciate your continued support and confidence in Nuveen and our family of investments.

Sincerely,

/s/  Timothy R. Schwertfeger
Timothy R. Schwertfeger
President

GENERAL INFORMATION

This Joint Proxy Statement is furnished in connection with the solicitation by the Board of Directors of each of Nuveen Performance Plus Municipal Fund, Inc. ("Performance Plus"), Nuveen Municipal Advantage Fund, Inc. ("Municipal Advantage"), Nuveen Investment Quality Municipal Fund, Inc. ("Investment Quality"), Nuveen Insured Quality Municipal Fund, Inc. ("Insured Quality"), Nuveen Select Quality Municipal Fund, Inc ("Select Quality"), Nuveen Quality Income Municipal Fund, Inc. ("Quality Income") and Nuveen Insured Municipal Opportunity Fund, Inc. ("Insured Municipal Opportunity") (individually, a "Fund" and, collectively, the "Funds"), of proxies to be voted at the Annual Meeting of Shareholders of each Fund to be held on July 25, 1996 (for each Fund, an "Annual Meeting" and, collectively, the "Annual Meetings"), and at any and all adjournments thereof.

On the matters coming before each Fund's Annual Meeting as to which a choice has been specified by the shareholders of that Fund on the proxy, the shares of that Fund will be voted accordingly. If no choice is so specified, the shares of each Fund will be voted FOR the election of the four nominees for director to be elected by all shareholders and the two nominees for director to be elected by holders of Money Market Cumulative Preferred Stock, in the case of Performance Plus, or Municipal Auction Rate Cumulative Preferred Stock ("MuniPreferred(R)") in the case of the other Funds (for convenience, shares of Performance Plus' Money Market Cumulative Preferred Stock shall also be referred to in this Joint Proxy Statement as shares of MuniPreferred), as listed in this Joint Proxy Statement, FOR ratification of the selection of Ernst & Young LLP as the Fund's independent auditors and FOR approval of the amendments to the terms of the Fund's MuniPreferred. Shareholders of any Fund who execute proxies may revoke them at any time before they are voted by filing with that Fund a written notice of revocation, by delivering a duly executed proxy bearing a later date, or by attending that Annual Meeting and voting in person.

The Board of Directors of each Fund has determined that the use of this Joint Proxy Statement for the Fund's Annual Meeting is in the best interest of the Fund and its shareholders in light of the similar matters being considered and voted on by the shareholders. Shareholders of each Fund will vote separately on each proposal relating to their Fund, and a vote on a proposal by the shareholders of one Fund will not affect the vote on the proposal by the shareholders of another Fund.

The following table indicates which shareholders are solicited with respect to each matter:

- --------------------------------------------------------------------------------------------------------
 MATTER                                                            COMMON STOCK        MUNIPREFERRED
- --------------------------------------------------------------------------------------------------------
 Election of Directors by all Shareholders (Ms. Impellizzeri and   X                   X
 Messrs. Brown, Dean and Sawers nominated for each Fund)
- --------------------------------------------------------------------------------------------------------
 Election of Directors by MuniPreferred only (Mrs. Rosenheim and                       X
 Mr. Schwertfeger nominated for each Fund)

 Ratify Selection of Auditors                                      X                   X
- --------------------------------------------------------------------------------------------------------
 Approval of amendments to the terms of the Fund's MuniPreferred   X                   X
- --------------------------------------------------------------------------------------------------------

A quorum of shareholders is required to take action at each Fund's Annual Meeting. A majority of the shares entitled to vote at each Annual Meeting, represented in person or by proxy, will constitute a quorum of shareholders at that Annual Meeting, except that for each Fund the election of the two nominees to be elected by holders of MuniPreferred, 33 1/3% of the MuniPreferred shares entitled to vote and represented in person or by proxy will constitute a quorum. Votes cast by proxy or in person at each Annual Meeting will be tabulated by the inspectors of election appointed for that Annual Meeting. The inspectors of election will determine whether or not a quorum is present at the Annual Meeting. The inspectors of election will treat abstentions and "broker non-votes" (i.e., shares held by brokers or nominees, typically in "street name," as to which (i) instructions have not been received from the beneficial owners or persons entitled to vote and

1

(ii) the broker or nominee does not have discretionary voting power on a particular matter) as present for purposes of determining a quorum.

For purposes of determining the approval of the matters submitted to the shareholders for a vote, abstentions and broker non-votes will be treated as shares voted against the election of directors, against ratification of the selection of independent auditors and against approval of the amendments to the terms of the Fund's MuniPreferred. The details of each proposal to be voted on by the shareholders of each Fund and the vote required for approval of each proposal are set forth under the description of each proposal below.

Shares of a series of MuniPreferred of a Fund held in "street name" for which voting instructions have not been received as of one business day before the meeting, or, if adjourned, one business day before the day to which the meeting is adjourned, and that would otherwise be treated as "broker non-votes" may, pursuant to Rule 452 of the New York Stock Exchange, be voted by the broker on each item in the same proportion as the votes cast by all MuniPreferred shareholders of that series of that Fund who have voted on the item.

As of May 28, 1996, there were issued and outstanding: shares of common stock and 4,000 shares of each series of MuniPreferred, Series M, T, W and F, of Performance Plus; shares of common stock and 3,000 shares of each series of MuniPreferred, Series M, T, W and F, of Municipal Advantage; shares of common stock and 2,500 shares of each series of MuniPreferred, Series M, T, W and F, of Investment Quality; shares of common stock and 2,600 shares of each series of MuniPreferred, Series M, T, W and F, of Insured Quality; shares of common stock and 2,000 shares of each series of MuniPreferred, Series M and T and 2,800 shares of each series of MuniPreferred Series W and F of Select Quality; shares of common stock, 3,000 shares of each series of MuniPreferred, Series M, T, W, and F and 4,000 shares of MuniPreferred, Series TH, of Quality Income; and shares of common stock and 4,000 shares of each series of MuniPreferred, Series M, T, W, TH1, TH2 and F of Insured Municipal Opportunity. Those persons who were shareholders of record at the close of business on May 28, 1996 will be entitled to one vote for each share held.

This Joint Proxy Statement is first being mailed to shareholders of the Funds on or about June , 1996.

SUMMARY OF PROPOSAL 3

Proposal 3 would amend the terms of the MuniPreferred in an effort to simplify investing in and owning shares of MuniPreferred. The proposal would, among other things, accomplish the following:

1. ELIMINATE MASTER PURCHASER'S LETTERS. A purchaser of MuniPreferred is presently required to sign a master purchaser's letter. In order to simplify the investment process, the proposal would eliminate this requirement.

2. INCREASE NUMBER OF EXTENDED RATE PERIODS. The Fund currently may extend a rate period from the minimum 7 days to 28 days, 182 days, 1 year, 3 years or 5 years. The proposal would provide the Fund with the ability to select an extended rate period of any length divisible by seven days up to five years. By providing the Fund with a greater number of extended rate periods to choose from, the Fund would have greater flexibility in managing its capital structure and MuniPreferred shareholders would have a wider range of investment choices.

3. ELIMINATE DEEMED HOLD ORDERS FOR EXTENDED RATE PERIODS. Currently, if a MuniPreferred shareholder fails to submit an order at an auction, such owner is deemed to have submitted a hold order. For rate periods of up to 28 days, a deemed hold order is viewed as a convenience to shareholders who wish to continue to hold shares, alleviating the need to submit an order at each weekly auction. To avoid, however, having MuniPreferred shareholders inadvertently hold MuniPreferred for rate periods of more than 28 days, the proposal would treat inaction on the part of shareholders when orders are due prior to a rate period of more than 28 days as a sell order.

Proposal 3 also would result in administrative conveniences and potential cost savings to the Fund.

The foregoing is a summary of certain provisions of Proposal 3 and should be read in conjunction with the full description of the Proposal. AS DESCRIBED THEREIN, THE BOARD OF DIRECTORS OF EACH FUND UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE APPROVAL OF PROPOSAL 3.

1. ELECTION OF DIRECTORS OF EACH FUND

At each Fund's Annual Meeting, six (6) directors are to be elected to serve until the next Annual Meeting and until their successors shall have been duly elected and qualified. Under the terms of each Fund's Articles of Incorporation, as amended, under normal circumstances holders of MuniPreferred are entitled to elect two (2) directors, and the remaining directors are to be elected by holders of common stock and MuniPreferred, voting together as a single class. The members of the Board of Directors and the nominees for election to the Board are the same for each Fund. Table I below shows the nominees for director of each Fund to be elected by holders of common stock and MuniPreferred, voting together as a single class. Table II below shows the nominees for director of each Fund to be elected by holders of MuniPreferred only. The affirmative vote of a majority of the shares present and entitled to vote at each Fund's Annual Meeting will be required to elect the directors of that Fund.

It is the intention of the persons named in the enclosed proxy to vote the shares represented thereby for the election of the nominees listed below unless the proxy is marked otherwise. Each of the nominees has agreed to serve as a director of each Fund if elected; however, should any nominee become unable or unwilling to accept nomination or election, the proxies for each Fund will be voted for one or more substitute nominees designated by that Fund's present Board of Directors.

Tables I and II below show each nominee's age, principal occupations and other business affiliations, the year in which each nominee was first elected or appointed a director of each Fund and the number of shares of common stock of the Funds and of all funds managed by Nuveen Advisory Corp. (excluding money market funds) which each nominee beneficially owned as of April 30, 1996. All of the nominees, except Anthony T. Dean, were last elected to the Board of Directors at the 1995 annual meeting of shareholders. Mr. Dean will be standing for election by each Fund's shareholders for the first time at the Annual Meeting to fill a vacancy that will occur upon the retirement of Richard J. Franke from each Fund's Board of Directors on June 30, 1996. Mr. Franke's contributions to the Funds are greatly appreciated. As of April 30, 1996, Mr. Franke owned 1,000 shares of each of Performance Plus, Municipal Advantage, Insured Quality, Select Quality, Quality Income and Insured Municipal Opportunity, and 500 shares of Investment Quality. In addition to the vacancy that will occur upon the retirement of Mr. Franke, there is currently another vacancy on each Fund's Board. Each Fund's nominating committee is considering candidates for that vacancy.

EACH FUND'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE ELECTION OF THE NOMINEES NAMED BELOW.

(3) The number shown reflects the aggregate number of common shares beneficially owned in all of the NAC Funds referred to in note (1) above (excluding money market funds).

The directors affiliated with John Nuveen & Co. Incorporated ("Nuveen") or Nuveen Advisory Corp. (the "Adviser") serve without any compensation from the Funds. Directors who are not affiliated with Nuveen or the Adviser receive a $45,000 annual retainer for serving as a director or trustee, as the case may be, of all funds sponsored by Nuveen and managed by the Adviser and a $1,000 fee per day plus expenses for attendance at all meetings held on a day on which a regularly scheduled Board meeting is held, a $1,000 fee per day plus expenses for attendance in person or a $500 fee per day plus expenses for attendance by telephone at a meeting held on a day on which no regular Board meeting is held, and a $250 fee per day plus expenses for attendance in person or by telephone at a meeting of the executive committee. The annual retainer, fees and expenses are allocated among the funds managed by the Adviser on the basis of relative net asset sizes. Each Fund has adopted a Directors' Deferred Compensation Plan pursuant to which a director of that Fund may elect to have all or a portion of the director's fee deferred. Directors may defer fees for any calendar year by the execution of a Participation Agreement prior to the beginning of the calendar year during which the director wishes to begin deferral.

The tables below show, for each director who is not affiliated with Nuveen or the Adviser, the aggregate compensation paid by each Fund for its fiscal year ended October 31, 1995 and the total compensation that Nuveen funds accrued for each director during the calendar year 1995, including any interest accrued for directors on deferred compensation. The rate of

5

earnings on deferred compensation is equivalent to the average net earnings rate, computed on a quarterly basis, on the shares of such Nuveen fund.

Richard J. Franke, Margaret K. Rosenheim and Timothy R. Schwertfeger currently serve as members of the executive committee of the Board of Directors of each Fund. The executive committee of each Fund, which meets between regular meetings of the Board of Directors, is authorized to exercise all of the powers of the Board of Directors. The respective executive committees of each Fund held twelve meetings during the fiscal year ended October 31, 1995.

Each Fund's Board of Directors has an audit committee composed of Lawrence H. Brown, Anne E. Impellizzeri, Margaret K. Rosenheim and Peter R. Sawers, directors who are not "interested persons." The audit committee reviews the work and any recommendations of the Fund's independent auditors. Based on such review, it is authorized to make recommendations to the Board of Directors. The respective audit committees of the Funds held two meetings during the fiscal year ended October 31, 1995.

Nomination of those directors who are not "interested persons" of each Fund is committed to a nominating committee composed of the directors who are not "interested persons" of that Fund. It identifies and recommends individuals to be nominated for election as non-interested directors. The nominating committees of each Fund held one meeting during the fiscal year ended October 31, 1995. No policy or procedure has been established as to the recommendation of director nominees by shareholders.

Each Fund's Board of Directors held five meetings during the fiscal year ended October 31, 1995. During the last fiscal year, each director attended 75% or more of each Fund's Board meetings and the committee meetings (if a member thereof), except that Mr. Franke was unable to attend certain executive committee meetings held solely to declare dividends. His attendance at executive committee meetings only which he was scheduled to attend was less than 75%.

Each Fund has the same executive officers. The following table sets forth information as of April 30, 1996 with respect to each executive officer of the Funds, other than executive officers who are directors and reflected above. Officers of the Funds receive no compensation from the Funds. The term of office of all officers will expire at the first meeting of the Board of Directors of each Fund after the Annual Meeting, which Board of Directors' meeting is presently scheduled to be held on July 25, 1996 for each Fund; however, as previously mentioned, Mr. Franke will be retiring from the Board of Directors effective June 30, 1996.

- -------------------------------------------------------------------------------------------------------

On April 30, 1996, directors and executive officers of the Funds as a group beneficially owned the following Fund shares: Performance Plus, no shares of common stock and 4 shares of MuniPreferred; Municipal Advantage, 16,265 shares of common stock (less than 1%) and no shares of MuniPreferred; Investment Quality, no shares of common stock or of MuniPreferred; Insured Quality, 5,260 shares of common stock (less than 1%) and no shares of MuniPreferred; Select Quality, no shares of common stock or of MuniPreferred; Quality Income, 750 shares of common stock (less than 1%) and 8 shares of MuniPreferred; and Insured Municipal Opportunity, 12,695 shares of common stock (less than 1%) and 2 shares of MuniPreferred. On April 30, 1996, directors, director nominees and executive officers of the Funds as a group beneficially owned 194,736 common shares of all funds managed by the Adviser (excluding money market funds). As of April 30, 1996, no person is known to the Funds to have owned beneficially more than five percent of the shares of Common Stock or MuniPreferred of any Fund.

Section 30(f) of the Investment Company Act of 1940, as amended (the "1940 Act"), and Section 16(a) of the Securities Exchange Act of 1934, as amended, require each Fund's officers and directors, investment adviser, affiliated persons of the investment adviser and persons who own more than ten percent of a registered class of the Funds' equity securities to file forms reporting their affiliation with that Fund and reports of ownership and changes in ownership of that Fund's shares with the Securities and Exchange Commission (the "SEC") and the New York Stock Exchange. These persons and entities are required by SEC regulation to furnish the Funds with copies of all Section 16(a) forms they file. Based on a review of these forms furnished to each Fund, each Fund believes that during the fiscal year ended October 31, 1995, all Section 16(a) filing requirements applicable to that Fund's officers and directors, investment adviser and affiliated persons of the investment adviser were complied with, except that one report on Form 5 was filed after the applicable deadline on behalf of Lawrence H. Brown in connection with his purchase of additional shares of common stock of Insured Municipal Opportunity.

2. SELECTION OF INDEPENDENT AUDITORS

The members of each Fund's Board of Directors who are not "interested persons" of that Fund have unanimously selected Ernst & Young LLP, independent public accountants, as independent auditors, to audit the books and records of that Fund for the fiscal year ending October 31, 1996. Ernst & Young LLP has served each Fund in this capacity since that Fund was organized and has no direct or indirect financial interest in that Fund except as independent auditors. The selection of Ernst & Young LLP as independent auditors of each Fund is being submitted to the shareholders for ratification, which requires the affirmative vote of a majority of the shares of each Fund present and entitled to vote on the matter. A representative of Ernst & Young LLP is expected to be present at the Annual Meetings and will be available to respond to any appropriate questions raised at the Annual Meetings and to make a statement if he or she wishes.

EACH FUND'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE RATIFICATION OF THE SELECTION OF INDEPENDENT AUDITORS.

3. AMENDMENT AND RESTATEMENT OF THE STATEMENT

The Board of Directors of each Fund has proposed that each Statement Establishing and Fixing the Rights and Preferences of MuniPreferred (the "Statement") for each Fund, be amended and restated. The proposed Amendment and Restatement (the "Amendment") would make certain changes to the terms of the Statement in order to provide greater flexibility, simplify and clarify the terminology and organization of the Statement and, in general, bring the Statement into conformity with the terms of MuniPreferred issued by other more recent Nuveen-sponsored closed-end funds, thereby resulting in administrative convenience and potential cost savings to the Fund.

EACH FUND'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE APPROVAL OF THE AMENDMENT.

Because the proposed separate amendments to the Statement for each Fund are interrelated and set forth in a single restatement of each such Fund's Statement, they will be voted upon by each Fund as a single amendment. For each Fund, the affirmative vote of the holders of at least a majority of the shares of common stock and shares of MuniPreferred present in person or by proxy and entitled to vote, voting as a single class, and the affirmative vote of the holders of at least 66 2/3% of the outstanding shares of each series of MuniPreferred, each voting as a separate class, are required to approve the Amendment.

Set forth below is a description and explanation of the various revisions to each Fund's Statement that are embodied in each such Fund's Amendment. To the extent a particular revision applies only to one or more Funds, it is generally because the revision is already incorporated into the Statement for the other Funds. Certain revisions, to the extent that they relate to a Taxable Allocation by a Fund and the resulting Gross-up payments, are not being proposed for Performance Plus because that Fund is not required to make Taxable Allocations by the Internal Revenue Service. Where a proposed revision is described as intended to clarify a provision of the Statement, the revision is designed to reflect the Board of Directors' interpretation of the current provision without making any substantive change.

Unless the context requires otherwise, capitalized terms used but not defined shall have the meanings ascribed to such terms in (a) the Statement or the Amendment and (b) Annex A hereto. The summary of the Amendment set forth below is qualified in its entirety by reference to the Amendment, a copy of which is available from the Fund upon request without charge.

A. DIVIDEND PAYMENT PROVISIONS (SECTION 2 OF PART I OF THE AMENDMENT)

1. FREQUENCY OF DIVIDEND PAYMENTS DURING SPECIAL RATE PERIODS

The Amendment would provide the Fund with the flexibility to pay dividends more frequently during Special Rate Periods. Current provisions in the Statement require dividends to be paid every fourth week after the first day of a 28-day Special Rate Period, approximately every 13th week during a 182-day Special Rate Period, and approximately every three months during longer Special Rate Periods. The Amendment provides that dividends on shares of MuniPreferred will be payable during Special Rate Periods consisting of 28 Rate Period Days or fewer on a weekly basis, and during any Special Rate Period consisting of more than 28 Rate Period Days, at such times as the Fund sets forth in the Notice of Special Rate Period. Since sellers of MuniPreferred are subject to taxation at capital gains rates on the portion of the sale price that represents accrued dividends, whereas the dividends when paid constitute tax-exempt income, the greater the amount of accrued dividends at a time when a holder sells shares of MuniPreferred outside of an Auction, the greater the possible adverse tax effect to the seller. This potential tax burden to sellers is likely to result in less favorable bids in an Auction for a Special Rate Period, thereby increasing the cost to the Fund of designating a Special Rate Period. The ability to fix more frequent Dividend Payment Dates during Special Rate Periods would reduce the amount of unpaid dividends that accrue between Dividend Payment Dates, which should result in a lower Applicable Rate for Special Rate Periods, thereby reducing the cost to the Fund of Special Rate Periods.

2. RESUMPTION OF AUCTIONS AFTER FAILURES TO DEPOSIT; LATE CHARGES

The Amendment, in order to conform the Statement to current Moody's guidelines, would require the Fund to arrange to pay a late charge to a beneficial owner of shares of MuniPreferred if there has been a Failure to Deposit with respect to such shares. The Moody's guidelines require the Fund, in addition to curing a Failure to Deposit before resuming Auctions for shares of MuniPreferred with respect to which such Failure to Deposit has occurred, to pay a late charge to beneficial owners of such shares before resuming Auctions therefor.

The Statement currently provides for each Fund except Performance Plus and Municipal Advantage, and is proposed to be amended to provide for Performance Plus and Municipal Advantage, that if any Failure to Deposit shall occur during any Rate Period of shares of MuniPreferred (other than any Special Rate Period of 4 or more Dividend Periods (1 year or more) or any Rate Period succeeding any Special Rate Period of 4 or more Dividend Periods during which a Failure to Deposit occurred that has not been cured), no Auction will be held for such shares for the next Rate Period thereof and the Fund shall pay dividends on such shares at a penalty rate for such next Rate Period. If, however, the Fund, at its option, cures such Failure to Deposit and pays a late charge prior to 12:00 Noon, New York City time, on the third business day next

8

succeeding the date on which such Failure to Deposit occurred, the penalty dividend rate will be lower than it would otherwise be. Further, the Fund's failure to pay the late charge will not result in the Fund's inability to resume Auctions for shares of MuniPreferred with respect to which there has been a Failure to Deposit. As long as the Fund cures such Failure to Deposit no later than 12:00 Noon, New York City time, on the fourth business day preceding any Auction Date for such shares, the Fund may resume Auctions for such shares on such date. If any Failure to Deposit shall occur during any Special Rate Period of shares of MuniPreferred of 4 or more Dividend Periods (or during any Rate Period succeeding any Special Rate Period of 4 or more Dividend Periods during which a Failure to Deposit occurred that has not been cured), the Fund shall pay dividends on such shares at a penalty rate for the next Rate Period thereof, but only if the Fund shall fail to cure such Failure to Deposit by 12:00 Noon, New York City time, on the fourth business day preceding the Auction Date for such next Rate Period. If the Fund so cures such Failure to Deposit, it may resume Auctions with respect to such shares on such Auction Date and pay dividends on such shares at the rate determined in Auctions.

For Performance Plus and Municipal Advantage, the Statement currently provides that if a Failure to Deposit with respect to shares of MuniPreferred shall occur during any Rate Period thereof (other than any Special Rate Period of 4 or more Dividend Periods or any Rate Period succeeding any Special Rate Period of 4 or more Dividend Periods during which a Failure to Deposit occurred that has not been cured), and such Failure to Deposit shall not have been cured and a late charge paid, in each case as of 12:00 Noon on the third business day next succeeding such Failure to Deposit, no Auctions will thereafter be held for such shares, and the dividend rate for such shares for each Dividend Period commencing after such Failure to Deposit shall be a rate per annum equal to 200% of LIBOR on the first day of each such Dividend Period. This provision was designed to enable the Fund to resume Auctions with respect to shares of MuniPreferred in the event of "ministerial" Failures to Deposit with respect to such shares (e.g., Failures to Deposit caused by inadvertence or communications mishaps) that are cured within 3 days, while compelling the Fund to pay a penalty dividend rate on such shares for so long as they remain outstanding in the event of Failures to Deposit that are not so cured. The Fund believes that the current provision is needlessly onerous. The Amendment would provide that the penalty dividend rate be the Maximum Rate, or in certain cases, a "stepped-up" Maximum Rate (i.e., the Maximum Rate, using for purposes of calculating the Rate Multiple, a prevailing rating that is deemed to be "Below ba3-/BB-"), instead of 200% of LIBOR. The Statement also currently provides that if any Failure to Deposit shall occur with respect to shares of MuniPreferred during a Special Rate Period of 4 or more Dividend Periods, or during any Rate Period succeeding any Special Rate Period of 4 or more Dividend Periods during which a Failure to Deposit occurred that has not been cured, the dividend rate for such shares for each Subsequent Rate Period thereof to and including the Subsequent Rate Period during which such Failure to Deposit is cured in accordance with the second preceding paragraph above shall be a rate per annum equal to 200% of the highest of (1) the Applicable Rate for such shares during such Special Rate Period, (2) the Treasury Rate for such Special Rate Period on the first day of each such Subsequent Rate Period and (3) the "AA" Composite Commercial Paper Rate for Minimum Rate Periods on the first day of each such Subsequent Rate Period. The Amendment would simplify the foregoing by providing that the penalty rate for such Subsequent Rate Periods will be a "stepped-up" Maximum Rate. Finally, as the Amendment would eliminate 200% of LIBOR as the penalty dividend rate, the Amendment would also delete the appropriate references to LIBOR from the Statement.

3. CALCULATION OF LATE CHARGE

The Amendment would provide that when the Fund is required to pay a late charge, the amount of the late charge would be determined by reference to one of several different benchmark rates, designed to conform with the length of the Rate Period in which such late charge is to be paid. Under current provisions of the Statement, a late charge is determined by reference to the "AA" Composite Commercial Paper Rate, which is a short-term benchmark rate. Because the Amendment grants enhanced flexibility with respect to determining the length of Special Rate Periods and enlarges the circumstances in which the Fund may be required to pay a late charge, the Fund believes that a short-term benchmark rate would not be appropriate for determining late charges occurring during such longer term Special Rate Periods. Accordingly, the Amendment would substitute the defined term "Reference Rate" for the "AA" Composite Commercial Paper Rate for this purpose. The "Reference Rate" embodies a number of different benchmark rates for different Rate Periods, permitting the selection of a rate that conforms more closely to the length of the Rate Period to which it applies.

4. ELIMINATE REQUIREMENT THAT DIVIDEND PAYMENT DATE MUST BE FOLLOWED BY A BUSINESS DAY [FOR PERFORMANCE PLUS, MUNICIPAL ADVANTAGE, INVESTMENT QUALITY, INSURED QUALITY AND SELECT QUALITY ONLY]

The Amendment would eliminate the requirement that dividends be paid on shares of MuniPreferred on a business day that is immediately followed by a business day. This requirement was designed to assure that beneficial owners of shares of MuniPreferred would be able to use their dividend payments on the day immediately following a Dividend Payment Date. Now, however, all the Broker-Dealers that participate in Auctions for shares of MuniPreferred have represented to the Funds that they or their affiliates will make dividends available in same-day funds on each Dividend Payment Date to the beneficial owners of shares of MuniPreferred for which they serve as Agent Members. Since beneficial owners of shares of MuniPreferred will receive dividends in same-day funds on Dividend Payment Dates, the requirement that the day after a Dividend Payment Date be a business day is no longer needed. This modification will benefit the Fund by minimizing the

9

number of times each year that regular Dividend Payment Dates must be moved to another day, thereby reducing the frequency of non-standard Rate Periods.

B. GROSS-UP PAYMENT PROVISIONS (SECTION 3 OF PART I, SECTION 5 OF PART II AND
SECTION 4 OF APPENDIX A TO THE AMENDMENT) [NOT APPLICABLE TO PERFORMANCE PLUS]

The Amendment would expand the circumstances under which the Fund would be required to make Gross-up Payments in order to provide greater certainty to investors, which should result in more favorable bids for shares of MuniPreferred at Auctions. The Amendment would require the Fund to make Gross-up Payments in the case of any Special Rate Period of more than 28 Rate Period Days whenever net capital gains or other income taxable for Federal income tax purposes is allocated to a dividend on shares of MuniPreferred with or without notice in advance of the Auction for the Special Rate period. The Fund believes that the proposed amendment is in its best interest because the Fund has determined that it may not be able to give advance notice of its intent to allocate net capital gains or other income taxable for Federal income tax purposes to dividends on shares of MuniPreferred in the case of such longer-term Special Rate Periods. Rather than have bidders in Auctions bid up the dividend rate for any such Special Rate Period because of the uncertainty of whether and to what extent the Fund might make such an allocation of taxable income, the Fund believes if it is required to make such Gross-Up Payments, bids placed in Auctions will result in lower dividend rates because of the greater certainty regarding taxable allocations.

In addition, the Amendment would change the way in which a Gross-up Payment is calculated to take into account the different Federal income tax rates applicable to ordinary income and net capital gains at the time such Gross-up Payment is made as opposed to when the related tax event occurred. The notification provisions applicable to Gross-up Payments also would be amended to require notification of the Gross-up Payment prior to the end of the calendar year in which the Gross-up Payment is made. Finally, the Amendment clarifies that a Gross-up Payment will not be made if a holder of MuniPreferred receives a Taxable Allocation upon a reallocation of income or gain by the Internal Revenue Service.

C. SPECIAL RATE PERIOD PROVISIONS (SECTION 4 OF PART I OF AMENDMENT)

1. GREATER FLEXIBILITY IN DESIGNATING SPECIAL RATE PERIODS

The Amendment would permit the Fund, at its option, to designate Special Rate Periods consisting of any number of Rate Period Days that is evenly divisible by seven and is not more than 1,820, subject to certain minor adjustments. This contrasts with the current provisions of the Statement, which only authorize Special Rate Periods of 28 or 182 Rate Period Days or 1, 3 or 5 years. The added flexibility will better enable the Fund to respond to changing market conditions in managing its capital structure.

2. NOTICE OF SPECIAL RATE PERIOD

The Amendment would permit the Fund to give less than the currently required 20 days written notice (by publication and mail) of the designation of a Special Rate Period, if the Auction Agent permits such shorter notice. It would also permit the Fund to notify the Auction Agent of its determination to exercise or not to exercise an option to proceed with a proposed Special Rate Period after the specified deadline of 11:00 a.m., New York City time, on the business day next preceding the first day of such Special Rate Period, if the Auction Agent agrees to accept such shorter notice. Both of these changes would give the Fund more time to make decisions concerning the designation of Special Rate Periods, thereby putting the Fund in a better position to respond to changing market conditions.

3.INFORMATION FOR RATING AGENCIES IN CONNECTION WITH NOTICE OF SPECIAL RATE PERIOD

The Amendment would make certain changes intended to more clearly describe the information required to be furnished to rating agencies together with a Notice of a Special Rate Period, to permit the rating agencies to determine that Moody's Eligible Assets or S&P's Eligible Assets at that time satisfy such rating agency guidelines.

4.REDEMPTION PRICE [FOR PERFORMANCE PLUS, MUNICIPAL ADVANTAGE AND INVESTMENT QUALITY ONLY]

The Amendment would provide that a designation of a Special Rate Period shall be effective if the Redemption Price of any shares of MuniPreferred that have been called for redemption have been deposited with the Auction Agent, as opposed to the current provisions of the Statement, which require the Redemption Price to have been paid to the holders of such shares.

5. OTHER REVISIONS

The Amendment would also make other conforming changes to make the language of the Statement consistent with the changes described above.

10

D. VOTING RIGHTS PROVISIONS (SECTION 5 OF PART I OF THE AMENDMENT)

1.RIGHT OF HOLDERS OF MUNIPREFERRED TO ELECT MAJORITY OF DIRECTORS UNDER CERTAIN CIRCUMSTANCES

The Amendment would clarify that holders of the Fund's preferred stock have the right to elect a majority of the Fund's directors (i) in the event that dividends on preferred stock have been in arrears for two years or (ii) pursuant to the provisions of the 1940 Act.

2. ISSUANCE OF ADDITIONAL PREFERRED STOCK [FOR PERFORMANCE PLUS, MUNICIPAL ADVANTAGE AND INVESTMENT QUALITY ONLY]

The Amendment would eliminate the requirement for shareholder approval to issue additional shares of Preferred Stock which would result in the aggregate liquidation preference of all shares of Preferred Stock outstanding exceeding a specified ceiling amount, which amount is set forth in the Statement, but only if Moody's or S&P is then rating the shares of MuniPreferred and only if each rating agency then rating shares of MuniPreferred confirms in writing to the Fund that such additional issuance would not impair the rating then assigned to shares of MuniPreferred by such rating agency.

The Statement currently provides that the Board of Directors, without the vote or consent to the holders of shares of MuniPreferred, but subject to certain rating agency approvals, may from time to time authorize and create, and the Fund may from time to time issue, classes or series of Preferred Stock ranking on a parity with shares of MuniPreferred with respect to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Fund, but only if, after giving effect to any such issuance, the aggregate liquidation preference of all shares of Preferred Stock of the Fund then outstanding, exclusive of accumulated and unpaid dividends, would not exceed the ceiling amount specified in the Statement. The Fund believes that, so long as either Moody's or S&P is rating the shares of MuniPreferred and the Fund is required--as a precondition for issuing additional shares of Preferred Stock--to obtain written confirmation from each rating agency then rating the shares of MuniPreferred that any such additional issuance would not impair the rating then assigned to shares of MuniPreferred by such rating agency, the holders of shares of MuniPreferred will be adequately protected in the event such additional issuance results in an aggregate liquidation preference of all shares of Preferred Stock outstanding, including MuniPreferred, in excess of the ceiling amount. Accordingly, the Fund proposes that the current ceiling be eliminated, as long as the precondition described above is satisfied. Although the Fund does not currently intend to issue additional shares of Preferred Stock, elimination of the ceiling would enable the Fund to manage its capital structure more efficiently in response to changing market conditions.

The Amendment would also clarify that any additional issuance of shares of Preferred Stock of the Fund will not be deemed to affect the preferences, rights or powers of holders of shares of MuniPreferred as long as each rating agency then rating the shares of MuniPreferred confirms in writing to the Fund that any such additional issuance would not impair the rating then assigned to shares of MuniPreferred by such rating agency.

3. ELIMINATE SUPERMAJORITY VOTE OF MUNIPREFERRED TO AUTHORIZE CERTAIN ACTIONS

The Amendment would decrease the number of shares of MuniPreferred required to approve certain actions of the Fund from 66 2/3% of the outstanding number of such shares to a majority thereof. The actions currently requiring the approval of a supermajority of MuniPreferred shares that would be affected by the Amendment include (i) the authorization, creation or issuance of stock, under certain circumstances, ranking prior to or on a parity with MuniPreferred with respect to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up of the Fund, or increasing the authorized amount of any series of MuniPreferred, or (ii) amending the Fund's Articles of Incorporation, including the Statement, whether by merger, consolidation or otherwise, so as to affect any preference, right or power of MuniPreferred or the holders thereof. The Fund believes that decreasing the number of shares required to approve these actions to a majority is in the best interest of the Fund, because it will eliminate the ability of the holders of a minority of shares of MuniPreferred to prevent the Fund from taking action that has been approved by the holders of at least a majority of such shares.

4. CLARIFY AUTHORITY OF THE FUND TO AMEND CERTAIN DEFINITIONS

The Fund is currently authorized to amend, alter or repeal certain definitions included in the Statement pursuant to requirements imposed by Moody's and S&P, provided that the Fund has received confirmation from each rating agency that the amendment would not impair the rating it has assigned to shares of MuniPreferred. The Amendment would extend this same authority to definitions included in the Statement as predicates for the definitions required by the rating agencies, subject to the same condition.

E. MUNIPREFERRED BASIC MAINTENANCE AMOUNT PROVISIONS


(SECTION 7 OF PART I OF THE AMENDMENT)

The Amendment would modify the occasions when the Fund must provide MuniPreferred Basic Maintenance Reports to Moody's and S&P, while retaining the current requirements regarding the furnishing of these reports to the Auction Agent.

11

The Amendment would also amend the definition of the term "Quarterly Valuation Date" to mean the last business day of each February, May, August and November of each year. These amendments are solely for the administrative convenience of the Fund and the rating agencies.

F. CERTAIN RATING AGENCY RESTRICTIONS (SECTION 10 OF PART I OF THE AMENDMENT)

1. BORROWING BY THE FUND

In conformity with rating agency guidelines, the Amendment would prohibit the Fund from borrowing money unless the Fund obtains written confirmation from Moody's or S&P, as appropriate, that the borrowing would not impair the rating assigned to shares of MuniPreferred by the rating agency, except that the Fund may borrow money for the purpose of clearing securities transactions if (i) the MuniPreferred Basic Maintenance Amount would continue to be satisfied after giving effect to such borrowing and (ii) such borrowing (A) is privately arranged with a bank or other person and is evidenced by a promissory note or other evidence of indebtedness that is not intended to be publicly distributed or (B) is for "temporary purposes" (i.e., the borrowing is to be repaid within 60 days and is not to be extended or renewed), is evidenced by a promissory note or other evidence of indebtedness and is in an amount not exceeding 5% of the value of the total assets of the Fund at the time of the borrowing for purposes of the foregoing.

2. ISSUANCE OF ADDITIONAL MUNIPREFERRED

The Amendment provides that, so long as Moody's or S&P is rating shares of MuniPreferred, the Fund could issue additional shares of existing series of MuniPreferred if it obtains prior confirmation that such issuance would not impair the rating assigned to such shares by the rating agency.

3. DESIGNATION OF PRICING SERVICE

The Amendment clarifies that, in conformity with S&P guidelines, the pricing service referred to in the definition of Market Value is J.J. Kenny.

G. REDEMPTION PROVISIONS (SECTION 11 OF PART I OF THE AMENDMENT)

1. OPTIONAL REDEMPTIONS DURING SPECIAL RATE PERIODS

The Amendment would provide that shares of MuniPreferred may be optionally redeemed on the second business day preceding each Dividend Payment Date during any Special Rate Period without the payment of a redemption premium, unless the applicable Notice of Special Rate Period provides otherwise, and that a Notice of Special Rate Period may provide otherwise only if the Board of Directors, in consultation with the Broker-Dealer(s) for such shares for such Special Rate Period, determines that placing restrictions on the Fund's ability to optionally redeem shares of MuniPreferred is in the best interest of the Fund. The Statement currently restricts optional redemption of MuniPreferred without a redemption premium to certain portions of certain Special Rate Periods. The Fund believes that by providing greater flexibility to optionally redeem shares of MuniPreferred during Special Rate Periods, the Amendment would enhance the utility of Special Rate Periods by permitting the Fund to tailor the redemption provisions applicable during such periods to the market conditions prevailing at the time.

2. REDEMPTION SUBJECT TO CONDITIONS PRECEDENT

The Statement currently provides that if the Fund mails a Notice of Redemption with respect to shares of MuniPreferred, it must redeem the shares of MuniPreferred subject thereto on the date fixed for redemption (or as soon as practicable thereafter if legally available funds are not available on that date). The Amendment would provide that the Board of Directors may establish conditions in a Notice of Redemption that must be satisfied before the Fund is obligated to effect any such redemption. The Fund believes that the Amendment would give the Board of Directors greater flexibility and avoid unnecessary costs associated with certain redemptions. For example, although the Fund does not currently intend to redeem shares of MuniPreferred, the current provision might have the effect of increasing the Fund's financing costs if the Fund were to redeem shares of MuniPreferred and issue new preferred shares in their place. Increased costs might result because the Fund effectively would be compelled to close the offering of the new shares of preferred stock before mailing a Notice of Redemption with respect to shares of MuniPreferred in order to be assured that it will have adequate funds available to effect the redemption--which, as described above, becomes mandatory upon the mailing of the Notice of Redemption--on the date fixed for redemption. This may lead to a situation in which the Fund must pay dividends both on the new shares of preferred stock and on the shares of MuniPreferred (until the date fixed for their redemption). Since the dividend rate that the Fund must pay on the new preferred shares may exceed the rate of return the Fund is able to obtain upon investing the proceeds of the offering of the new shares, the Fund may experience losses resulting from "negative arbitrage." The proposed amendment would permit the Fund to provide in a Notice of Redemption that the redemption of shares of MuniPreferred is conditioned on the closing of the offering of the new preferred shares, thereby enabling the Fund to structure financings such that the redemption of the shares of MuniPreferred occurs simultaneously upon the closing of the new offering, which would eliminate the need to pay dividends simultaneously on both the shares of MuniPreferred and the new shares of preferred stock.

12

3. RATING AGENCY CONDITIONS

In order to conform the statement to current Moody's guidelines, the Amendment would (i) clarify (for each Fund except Performance Plus and Municipal Advantage) and provide (for Performance Plus and Municipal Advantage) that the Fund may not on any date mail a Notice of Redemption relating to an optional redemption of shares of MuniPreferred unless on such date the Discounted Value of Moody's Eligible Assets (if Moody's is then rating shares of MuniPreferred) and the Discounted Value of S&P Eligible Assets (if S&P is then rating the shares of MuniPreferred) each at least equal the MuniPreferred Basic Maintenance Amount, and would at least equal the MuniPreferred Basic Maintenance Amount immediately subsequent to such redemption if such redemption were to occur on such date and (ii) provide that, for this purpose, the Moody's Discount Factors applicable to Moody's Eligible Assets shall be determined by reference to the first Exposure Period longer than the Exposure Period then applicable to the Fund, as described in the definition of Moody's Discount Factor.

For Performance Plus, the Amendment would provide that the Fund must effect a mandatory redemption of Shares of MuniPreferred on or prior to the 40th day after the relevant Cure Date (as opposed to the 45th day, as is currently the case) in order to conform the Statement to current Moody's guidelines.

4. DECREASE NOTICE REQUIREMENT [FOR PERFORMANCE PLUS, MUNICIPAL ADVANTAGE AND INVESTMENT QUALITY ONLY]

The Statement currently provides that, in the event the Fund determines or is required to redeem shares of MuniPreferred, it must mail a Notice of Redemption with respect to such shares to the holders thereof not less than 30 nor more than 45 days prior to the date fixed for redemption. The Amendment would substitute 20 days for 30 days in order to enhance the Fund's flexibility with respect to the timing of optional redemptions.

H. LIQUIDATION RIGHTS (SECTION 12 OF PART I OF THE AMENDMENT)

The Amendment would amend the liquidation rights provisions contained in the Statement to clarify that accumulated dividends payable in connection with a dissolution, liquidation or winding up of affairs of the Fund will accumulate to, but will not include, the date of final distribution.

I. MISCELLANEOUS PROVISIONS (SECTION 13 OF PART I OF THE AMENDMENT)

The Amendment would provide, for the administrative convenience of the Fund, that the Fund may, by resolution of its Board of Directors duly adopted and without shareholder approval, amend the Amendment to add additional shares to an existing series of MuniPreferred (and terms relating thereto) to the series and shares of MuniPreferred theretofore described therein, provided the Fund obtains certain rating agency approvals. However, the Fund does not currently intend to issue additional shares of an existing series of MuniPreferred.

The Statement currently provides that any shares of MuniPreferred that at any time have been redeemed or purchased by the Fund shall, after such redemption or purchase, have the status of authorized but unissued preferred shares. The Amendment would amend the Statement to provide that shares of MuniPreferred which are redeemed, exchanged or otherwise acquired by the Fund shall return to the status of authorized and unissued shares of Preferred Shares without designation as to series. Upon the redemption, exchange or other acquisition by the Fund of all outstanding shares of a series of MuniPreferred, all provisions of the Articles relating to such series (including, without limitation, all provisions of the Amendment relating to such series) shall cease to be of further effect and shall cease to be part of the Articles.

The Amendment would delete the provision in the Statement that any notice given under the Statement shall be deemed given on the earlier of the date received or the date seven days after which such notice is mailed. This provision has no independent significance in the Statement and may be read to conflict with other notice provisions in the Amendment.

J. AUCTION PROCEDURES (PART II OF THE AMENDMENT)

1. ELIMINATION OF MASTER PURCHASER'S LETTER

The Amendment would alter the Auction Procedures contained in the Statement to eliminate the requirement that a purchaser of shares execute a Master Purchaser's Letter. The Statement currently provides that a prospective beneficial owner of shares of MuniPreferred must execute a Master Purchaser's Letter. The Fund proposes to eliminate this requirement in order to simplify the investment process. In its place, unless the Fund permits otherwise, only Broker-Dealers (who, in their broker-dealer agreements with the Fund, will bind themselves to the types of provisions contained in a Master Purchaser's Letter) will be considered Existing Holders for purposes of submitting orders to the Auction Agent. The Amendment also provides that, unless the Fund permits otherwise, a beneficial owner of shares of MuniPreferred may sell, transfer or otherwise dispose of shares of MuniPreferred only pursuant to a bid or sell order placed by such beneficial owner's Broker-Dealer with the Auction Agent or to a Broker-Dealer (provided that a sale, transfer or other disposition of shares of MuniPreferred from a customer of a Broker-Dealer who is listed on the records of that Broker-Dealer shall not be deemed to be a sale, transfer or other disposition for purposes of the foregoing if such Broker-Dealer remains the Existing Holder of the shares to be sold, transferred or disposed of immediately after such sale, transfer or disposition).

13

In order to effectuate the foregoing proposals, the Amendment would modify certain provisions of the Auction Procedures, as well as the definitions of Existing Holder and Potential Holder, and would add definitions of "Beneficial Owner" and "Potential Beneficial Owner."

2. TRANSFER OF MUNIPREFERRED

The Amendment is designed to preserve the results of an Auction to the greatest extent practicable in the event an Existing Holder or Beneficial Owner of shares of MuniPreferred fails to deliver any shares of MuniPreferred that it is required to deliver under the Auction Procedures. Thus, a bidder for shares of MuniPreferred in an Auction would not be permitted to break its purchase simply because, by reason of a seller's failure to deliver, the bidder is not able to purchase all the shares for which it had bid. The Statement currently provides that in the case of any transfer of shares of MuniPreferred outside of an Auction, the Existing Holder of such shares, its Broker-Dealer or its Agent Member has the obligation to advise the Auction Agent of the transfer. The Fund believes that it is more appropriate to place that obligation on the Broker-Dealer transferee (or other permitted transferee) rather than on the transferor, and that placing that obligation on the transferee will result in a more accurate tracking of owners of shares of MuniPreferred and, consequently, a more efficient Auction process.

Experience with the various Nuveen-sponsored closed-end investment companies has shown that their shares of auction-rate cumulative preferred stock are frequently transferred outside of auctions without compliance with applicable notification provisions, making it difficult for the Auction Agent to maintain an accurate registry of owners for the purpose of conducting auctions. The Amendment is designed to remedy the possible confusion that may result, by giving the Auction Agent conclusive and binding authority to determine the Existing Holders of shares of MuniPreferred for the purpose of conducting Actions. However, as the Amendment might cause unreasonable hardship to a Broker-Dealer in situations where the Auction Agent has determined that the Broker-Dealer is the Existing Holder of a greater number of shares than the number of shares which the Broker-Dealer believes itself to be the Existing Holder of--resulting in potential liability to the Broker-Dealer if the Broker-Dealer fails to deliver the "excess" shares pursuant to sell orders, it would provide relief from that liability if the Broker-Dealer indicates to the Auction Agent that it does not believe that it is the Existing Holder of the "excess" shares. The Amendment would also provide similar relief to a Broker-Dealer who is deemed to submit a sell order in respect of shares that were transferred without compliance with applicable notification requirements.

3. ADJUSTMENTS TO MAXIMUM RATE

The Amendment would provide that the Maximum Rate for Rate Periods consisting of fewer than 28 Rate Period Days shall be determined by reference to a percentage based on the credit rating of the shares times the higher of the applicable "AA" Composite Commercial Paper Rate or the Taxable Equivalent of the Short-Term Municipal Bond Rate. The Statement currently provides that the Maximum Rate payable on shares of MuniPreferred for any Minimum Rate Period thereof or any Special Rate Period thereof consisting of 28 Rate Period Days be determined by reference to a percentage based on the credit rating of the shares times the applicable "AA" Composite Commercial Paper Rate.

Under certain market conditions, the Fund has observed that the Maximum Rate determined by using the applicable "AA" Composite Commercial Paper Rate has been lower than the Maximum Rate that would have been determined by using the taxable equivalent of an index based on municipal bonds. Bids above the Maximum Rate submitted by Existing Holders are treated like sell orders and bids by Potential Holders above the Maximum Rate are rejected. Therefore, raising the permissible Maximum Rate should give greater assurance that Sufficient Clearing Bids will continue to exist in Auctions for shares of MuniPreferred (i.e., that Auctions will be successful). While raising the permissible Maximum Rate could, in certain circumstances, increase the amount of dividends that the Fund might otherwise be required to pay on the shares of MuniPreferred and, to that extent, decrease the amount of net investment income that might otherwise be available for distribution to holders of shares of Common Stock, the Fund believes that the proposed Maximum Rate provisions should help assure the holders of shares of MuniPreferred that they will be able to sell their shares of MuniPreferred in Auctions when they so desire. As a result of this greater certainty, the proposed Maximum Rate provisions would preserve the efficiency of the shares of MuniPreferred as a financing vehicle for the Fund.

4.MAXIMUM RATE FOR SPECIAL RATE PERIODS OF MORE THAN 182 DAYS BUT LESS THAN 365 DAYS

The Fund proposes to substitute the term "Treasury Bill Rate" for "AA" Composite Commercial Paper Rate for purposes of determining the Maximum Rate in respect of Special Rate Periods of more than 182 but fewer than 365 Rate Period Days. The Fund believes that the Treasury Bill Rate is more appropriate than the "AA" Composite Commercial Paper Rate in those circumstances because it more precisely correlates to the length of such Special Rate Periods.

The Statement currently provides that, in the case of Special Rate Periods of less than 1 year, the Maximum Rate on shares of MuniPreferred shall be equal to a percentage based on the credit rating of such shares times the applicable "AA" Composite Commercial Paper Rate. However, the only Special Rate Periods of less than 1 year that may now be designated by the Fund are Special Rate Periods of 28 Rate Period Days or 182 Rate Period Days--for which the applicable "AA" Composite Commercial Rate, in the Fund's judgment, is a suitable rate for purposes of determining the Maximum Rate (except as described above under "Adjustments to Maximum Rate"). However, if the Fund is granted enhanced flexibility

14

with respect to determining the length of Special Rate Periods of more than 182 but fewer than 365 Rate Period Days, the "AA" Composite Commercial Paper Rate, in the Fund's judgment, is not suitable.

Further, the Fund proposes to revise the definition of "AA" Composite Commercial Paper Rate to accommodate Special Rate Periods of between 14 and 182 Rate Period Days.

5. FEDERAL TAX RATE USED TO CALCULATE RATE MULTIPLE [NOT APPLICABLE TO PERFORMANCE PLUS]

The definition of "Rate Multiple" currently provides that, in the event the Fund has notified the Auction Agent of its intent to allocate taxable income to shares of MuniPreferred prior to the Auction establishing the dividend rate for such shares, the applicable percentage in the table contained in the definition of "Rate Multiple" shall be divided by the quantity 1 minus the maximum marginal regular Federal income tax rate applicable to ordinary income or the maximum marginal regular Federal corporate income tax rate, whichever is greater. The Amendment would substitute for the quantity described above, the quantity 1 minus the maximum marginal regular Federal income tax rate applicable to ordinary income or the maximum marginal regular Federal corporate income tax rate applicable to ordinary income, whichever is greater. The purpose of the substitution is to clarify that the Federal income tax rates applicable to ordinary income, as opposed to rates applicable to net capital gain, are to be used for purposes of deriving the Rate Multiple.

6. DIVIDEND RATE DETERMINATIONS FOR ALL HOLD ORDERS

The proposed amendments to the formula for determining the dividend rate applicable to shares of a series of MuniPreferred in the event all shares of such series are the subject of hold orders in an Auction for shares of such series (i.e.; an "all hold order rule") are designed to accommodate the Fund's proposed enhanced flexibility with respect to determining the length of Special Rate Periods by varying the benchmark rates used in calculating the applicable dividend rates depending on the length of the Special Rate Periods.

For Performance Plus, the Amendment would tax-adjust the "AA" Composite Commercial Paper Rate to take into account the higher of the maximum marginal regular Federal individual income tax rate applicable to ordinary income or the maximum marginal regular Federal corporate income tax rate applicable to ordinary income.

In addition, for each Fund, the Amendment would provide that, in the event all shares of a series of MuniPreferred are the subject of hold orders in an Auction for a Special Rate Period consisting of fewer than 183 Rate Period Days, the Applicable Rate shall be equal (or determined by reference) to the lesser of (i) the Kenny Index and (ii) the product of (x) the applicable "AA" Composite Commercial Paper Rate and (y) 1 minus the maximum marginal regular Federal income tax rate applicable to ordinary income or the maximum marginal regular Federal corporate income tax rate applicable to ordinary income, whichever is greater. As the Kenny Index represents a tax-free rate, the Fund believes that it is a more appropriate benchmark rate for purposes of determining the all hold order rate than the applicable tax-adjusted "AA" Composite Commercial Paper Rate.

7. DEEMED SELL ORDERS FOR CERTAIN SPECIAL RATE PERIODS

The Statement currently provides that if a beneficial owner of shares of MuniPreferred fails to submit an order in respect of those shares in an Auction, such beneficial owner will be deemed to have submitted a hold order in respect of those shares. The Fund believes that in the usual case--where Auctions for shares of MuniPreferred are held relatively frequently (i.e., on a weekly basis)--this "deemed hold order" mechanism provides convenience to beneficial owners in that it relieves them of the need to submit an order to their Broker-Dealer in situations where they desire to continue to hold shares of MuniPreferred regardless of the dividend rate thereon.

However, if the Fund designates a relatively long-term Special Rate Period and a short-term investor in shares of MuniPreferred neglects to place a sell order in the Auction for such Special Rate Period, the investor may be locked into a longer term investment that he or she does not want. To guard against this possibility, the Fund proposes that, in the event an investor fails to place an order in respect of shares of MuniPreferred in an Auction for a Special Rate Period of more than 28 Rate Period Days, the investor will be deemed to have placed a sell order in respect of those shares.

8. GLOBAL CERTIFICATE

The Statement currently provides that all of the shares of each series of MuniPreferred outstanding from time to time shall be represented by one global certificate registered in the name of DTC or its nominee. The purpose of this provision is to assure maximum administrative convenience to the Fund and the Auction Agent in connection with paying dividends on shares of MuniPreferred and conducting Auctions with respect thereto. The proposed amendments would amend the current provision by providing that it shall be effective only prior to the commencement of any right of holders of preferred shares to elect a majority of the Fund's directors.

9. MISCELLANEOUS

Finally, the Amendment would update and add certain definitions to the Statement to conform the Statement to current rating agency guidelines; would make certain other minor changes to the Statement; and would correct typographical errors and omissions and inaccurate cross-references.

15

In the case of Performance Plus, the Amendment would redesignate the shares of "Money Market Cumulative Preferred Stock ("MMP")" as "Municipal Auction Rate Cumulative Preferred Stock ("MuniPreferred")." In the case of Municipal Advantage and Investment Quality, the Amendment would change the name of the shares of MuniPreferred issued pursuant to each respective statement from "MPS" to "MuniPreferred."

ANNEX A

GLOSSARY OF TERMS

"'AA' COMPOSITE COMMERCIAL PAPER RATE," on any date for any Rate Period of shares of a series of MuniPreferred, shall mean (i) (A) in the case of any Minimum Rate Period or any Special Rate Period of fewer than 49 Rate Period Days, the interest equivalent of the 30-day rate; provided, however, that if such Rate Period is a Minimum Rate Period and the 'AA' Composite Commercial Paper Rate is being used to determine the Applicable Rate for shares of such series when all of the Outstanding shares of such series are subject to Submitted Hold Orders, then the interest equivalent of the seven-day rate, and (B) in the case of any Special Rate Period of (1) 49 or more but fewer than 70 Rate Period Days, the interest equivalent of the 60-day rate; (2) 70 or more but fewer than 85 Rate Period Days, the arithmetic average of the interest equivalent of the 60-day and 90-day rates; (3) 85 or more but fewer than 99 Rate Period Days, the interest equivalent of the 90-day rate; (4) 99 or more but fewer than 120 Rate Period Days, the arithmetic average of the interest equivalent of the 90-day and 120-day rates; (5) 120 or more but fewer than 141 Rate Period Days, the interest equivalent of the 120-day rate; (6) 141 or more but fewer than 162 Rate Period Days, the arithmetic average of the 120-day and 180-day rates; and (7) 162 or more but fewer than 183 Rate Period Days, the interest equivalent of the 180-day rate, in each case on commercial paper placed on behalf of issuers whose corporate bonds are rated "AA" by S&P or the equivalent of such rating by S&P or another rating agency, as made available on a discount basis or otherwise by the Federal Reserve Bank of New York for the Business Day next preceding such date; or (ii) in the event that the Federal Reserve Bank of New York does not make available any such rate, then the arithmetic average of such rates, as quoted on a discount basis or otherwise, by the Commercial Paper Dealers to the Auction Agent for the close of business on the Business Day next preceding such date. If any Commercial Paper Dealer does not quote a rate required to determine the "AA" Composite Commercial Paper Rate, the "AA" Composite Commercial Paper Rate shall be determined on the basis of the quotation or quotations furnished by the remaining Commercial Paper Dealer or Commercial Paper Dealers and any Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers selected by the Fund to provide such rate or rates not being supplied by any Commercial Paper Dealer or Commercial Paper Dealers, as the case may be, or, if the Fund does not select any such Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers, by the remaining Commercial Paper Dealer or Commercial Paper Dealers. For purposes of this definition, the "interest equivalent" of a rate stated on a discount basis (a "discount rate") for commercial paper of a given days' maturity shall be equal to the quotient (rounded upwards to the next higher one-thousandth (.001) of 1%) of (A) the discount rate divided by (B) the difference between (x) 1.00 and (y) a fraction the numerator of which shall be the product of the discount rate times the number of days in which such commercial paper matures and the denominator of which shall be 360.

"AFFILIATE" shall mean, for purposes of the definition of "Outstanding," any Person known to the Auction Agent to be controlled by, in control of or under common control with the Fund; provided, however, that no Broker-Dealer controlled by, in control of or under common control with the Fund shall be deemed to be an Affiliate nor shall any corporation or any Person controlled by, in control of or under common control with such corporation one of the directors, trustees or executive officers of which is a director of the Fund be deemed to be an Affiliate solely because such director, trustee or executive officer is also a director of the Fund.

At the upcoming Annual Meeting, all shareholders will be asked to consider and approve a very important proposal. The Fund's management seeks to update the terms of the Municipal Auction Rate Cumulative Preferred Stock (MuniPreferred(R)) to conform with the state-of-the-art terms of more recent MuniPreferred offerings (as more fully described in the enclosed proxy statement). We believe the proposals will provide a wider range of investment choices and simplify investing in and owning shares of MuniPreferred, potentially providing you with an even better investment. If approved, the terms of the MuniPreferred would be amended to, among other things, offer the following advantages:

/ / Eliminate Master Purchaser's Letters / / Refine Maximum Dividend Rate Provisions / / Increase Flexibility in Establishing Extended Rate Periods

At the upcoming Annual Meeting, all shareholders will be asked to consider and approve a very important proposal. The Fund's management seeks to update the terms of the Municipal Auction Rate Cumulative Preferred Stock (MuniPreferred(R)) to conform with the state-of-the-art terms of more recent MuniPreferred offerings (as more fully described in the enclosed proxy statement). We believe the proposals will provide a wider range of investment choices and simplify investing in and owning shares of MuniPreferred, potentially providing you with an even better investment. If approved, the terms of the MuniPreferred would be amended to, among other things, offer the following advantages:

/ / Eliminate Master Purchaser's Letters / / Refine Maximum Dividend Rate Provisions / / Increase Flexibility in Establishing Extended Rate Periods

WHETHER OR NOT YOU PLAN TO JOIN US, PLEASE COMPLETE, DATE AND SIGN YOUR PROXY CARD AND RETURN IT IN THE ENCLOSED ENVELOPE SO THAT YOUR VOTE WILL BE COUNTED.
