Nuveen Municipal High Income Opportunity Fund is a recently organized, diversified, closed-end management investment company. The Fund's primary investment objective is to provide high current income exempt from regular federal income tax. The Fund's secondary investment objective is to seek attractive total return consistent with its primary objective. Under normal circumstances, the Fund will invest its Managed Assets (as defined on page 1 of the prospectus) in a portfolio of municipal securities that pay interest that is exempt from regular federal income tax. Under normal circumstances, the Fund expects to be fully invested in such tax-exempt municipal securities. Up to 30% of the Fund's Managed Assets may be invested in municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to individuals. The Fund will invest at least 50% of its Managed Assets in municipal securities that at the time of investment are investment grade quality. A security is considered investment grade quality if it is rated within the four highest grades by all nationally recognized statistical rating organizations that rate such security, or if it is unrated but judged to be of comparable quality by the Fund's investment adviser. The Fund may invest up to 50% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade quality or that are unrated but judged to be of comparable quality by the Fund's investment adviser. No more than 5% of the Fund's Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by the Fund's investment adviser. Municipal securities of below investment grade quality are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as junk bonds. The Fund cannot assure you that it will achieve its investment objectives.

The Fund's principal office is located at 333 West Wacker Drive, Chicago, Illinois 60606, and its telephone number is (800) 257-8787.

PROSPECTUS SUMMARY

This is only a summary. You should review the more detailed information contained elsewhere in this prospectus and in the Statement of Additional Information, including the Fund's Statement Establishing and Fixing the Rights and Preferences of MuniPreferred Shares (the "Statement") attached as Appendix A to the Statement of Additional Information. Capitalized terms used but not defined in this prospectus shall have the meanings given to such terms in the Statement.

The Fund......................   Nuveen Municipal High Income Opportunity Fund
                                 (the "Fund") is a recently organized,
                                 diversified, closed-end management investment
                                 company. See "The Fund." The Fund's common
                                 shares, $.01 par value ("common shares"), are
                                 traded on the American Stock Exchange (the
                                 "Exchange") under the symbol "NMZ." See
                                 "Description of Common Shares." As of January
                                 8, 2004, the Fund had 23,157,000 common shares
                                 outstanding and net assets of $338,536,433.


Investment Objectives.........   The Fund's primary investment objective is to
                                 provide high current income exempt from regular
                                 federal income tax. The Fund's secondary
                                 investment objective is to seek attractive
                                 total return consistent with its primary
                                 objective. The Fund seeks to achieve its
                                 investment objectives by investing in municipal
                                 securities that its investment adviser believes
                                 are underrated and undervalued. The Fund cannot
                                 assure you that it will achieve its investment
                                 objectives. See "The Fund's Investments" and
                                 "Risk Factors."

                                 Under normal circumstances, the Fund will
                                 invest its assets, including assets
                                 attributable to MuniPreferred shares, ("Managed
                                 Assets") in a portfolio of municipal securities
                                 that pay interest that is exempt from regular
                                 federal income tax. Under normal circumstances,
                                 the Fund expects to be fully invested in such
                                 tax-exempt municipal securities. Up to 30% of
                                 the Fund's Managed Assets may be invested in
                                 municipal securities that pay interest that is
                                 taxable under the federal alternative minimum
                                 tax applicable to individuals. For a discussion
                                 of how the federal alternative minimum tax may
                                 affect shareholders, see "Federal Income Tax
                                 Matters."


                                 The Fund will invest at least 50% of its
                                 Managed Assets in municipal securities that at
                                 the time of investment are investment grade
                                 quality. A security is considered investment
                                 grade quality if it is rated within the four
                                 highest grades (Baa or BBB or better by Moody's
                                 Investors Service, Inc. ("Moody's"), Standard &
                                 Poor's Corporation, a division of The McGraw
                                 Hill Companies ("S&P") or Fitch Ratings
                                 ("Fitch")) by all nationally recognized
                                 statistical rating organizations (each a
                                 "NRSRO") that rate such security, or if it is
                                 unrated but judged to be of comparable quality
                                 by the Fund's investment adviser.


                                 The Fund may invest up to 50% of its Managed
                                 Assets in municipal securities that, at the
                                 time of investment, are rated below investment
                                 grade or that are unrated but judged to be of
                                 comparable quality by the Fund's investment
                                 adviser. Below investment grade quality
                                 municipal securities include those municipal
                                 securities that are rated investment grade by
                                 one or more NRSROs but rated below investment
                                 grade by at least one

1

NRSRO. No more than 5% of the Fund's Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Advisory (as defined below). This means that the Fund may invest in municipal securities that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition (such securities are commonly referred to as distressed securities).

                                 The Fund anticipates that, upon the full
                                 investment of the net proceeds from this
                                 offering (which is expected to occur within two
                                 to three months following the closing of this
                                 offering), it will have invested approximately
                                 55% to 65% of its Managed Assets in investment
                                 grade municipal securities and approximately
                                 35% to 45% of its Managed Assets in below
                                 investment grade municipal securities. The
                                 relative percentages of the value of the Fund's
                                 Managed Assets attributable to investment grade
                                 municipal securities and to below investment
                                 grade municipal securities could change over
                                 time as a result of rebalancing the Fund's
                                 assets by Nuveen Advisory, market value
                                 fluctuations and other events.

                                 Bonds of below investment grade quality are
                                 regarded as having predominately speculative
                                 characteristics with respect to capacity to pay
                                 interest and repay principal, and are commonly
                                 referred to as junk bonds. The Fund cannot
                                 assure you that it will attain its investment
                                 objectives. See "The Fund's Investments" and
                                 "Risk Factors -- Credit and Below Investment
                                 Grade Risk."

                                 The Fund may invest in municipal securities in
                                 the form of notes, which are generally used to
                                 provide for short-term capital needs in
                                 anticipation of an issuer's receipt of other
                                 revenues or financing, and typically have
                                 maturities of up to three years. Such
                                 instruments may include tax anticipation notes,
                                 revenue anticipation notes, bond anticipation
                                 notes, tax and revenue anticipation notes and
                                 construction loan notes. In addition, the Fund
                                 may invest in municipal leases, certificates of
                                 participation and "moral obligation" bonds. The
                                 Fund also may invest in municipal securities in
                                 the form of tender option bonds. The Fund will
                                 not invest in inverse floating rate securities,
                                 which are securities that pay interest at rates
                                 that vary inversely with changes in prevailing
                                 short-term tax-exempt interest rates and which
                                 represent, in effect, a leveraged investment in
                                 an underlying municipal security. See "The
                                 Fund's Investments."

Risk Factors Summary..........   Risk is inherent in all investing. Therefore,
                                 before investing in the Fund you should
                                 consider certain risks carefully. The primary
                                 risks of investing in MuniPreferred shares are:

                                 - if an auction fails you may not be able to
                                   sell some or all of your shares;


                                 - because of the nature of the market for
                                   MuniPreferred shares, you may not be able to
                                   sell your shares outside of the auction, or
                                   if you do sell your shares outside of the
                                   auction, you may receive less than the price
                                   you paid for your shares, especially when
                                   market interest rates are rising;

- any inability to sell MuniPreferred shares outside of an auction and any rise in market interest rates relative to the dividend rates on the MuniPreferred shares may have a particularly adverse impact on the value of Series T and Series W shares during their respective Extended Initial Rate Period;

- a rating agency could downgrade MuniPreferred shares, which could affect liquidity;

- the Fund may be forced to redeem your shares to meet regulatory or rating agency requirements or may voluntarily redeem your shares in certain circumstances;

- in extraordinary circumstances the Fund may not earn sufficient income from its investments to pay dividends;

- if long-term interest rates rise, the value of the Fund's investment portfolio will decline, reducing the asset coverage for the MuniPreferred shares; and

- if an issuer of a municipal bond in which the Fund invests is downgraded or defaults, there may be a negative impact on the income and/or asset value of the Fund's portfolio.

For additional general risks of investing in MuniPreferred shares of the Fund, see "Risk Factors."

Trading Market................   MuniPreferred shares are not listed on an
                                 exchange. Instead, you may buy or sell
                                 MuniPreferred shares at an auction by
                                 submitting orders to a broker-dealer that has
                                 entered into an agreement with the auction
                                 agent and the Fund (a "Broker-Dealer"), or to a
                                 broker-dealer that has entered into a separate
                                 agreement with a Broker-Dealer. After the
                                 initial rate period, auctions for subsequent
                                 rate periods are normally held weekly, unless
                                 they are designated in advance as a special
                                 rate period, as described in detail below. The
                                 initial auction for Series T and Series W will
                                 not be held until the end of each series'
                                 respective Extended Initial Rate Period, which
                                 may be up to three years from the date of this
                                 offering. If, at the end of the Extended
                                 Initial Rate Period for each of Series T and
                                 Series W, respectively, the Board of Trustees,
                                 as presently anticipated, determines not to
                                 designate the subsequent rate period as a
                                 special rate period, that subsequent rate
                                 period would be a minimum rate period of 7
                                 days, and shareholders of those series who
                                 submit Hold Orders or fail to submit any Order
                                 in the auction for that subsequent rate period
                                 would thereafter own MuniPreferred

3

shares having the characteristics of shares of series having 7 day rate periods, as described in this prospectus.

In addition to the auctions, Broker-Dealers and other broker-dealers may maintain a secondary trading market in MuniPreferred shares outside of auctions, but may discontinue this activity at any time. There is no assurance that a secondary market will provide shareholders with liquidity. You may transfer shares outside of auctions only to or through a Broker-Dealer, or a broker-dealer that has entered into a separate agreement with a Broker-Dealer.

The table below shows the first auction date for each Series of MuniPreferred shares and the day on which each subsequent auction will normally be held for each Series of MuniPreferred shares. The first auction date for the series of MuniPreferred shares will be the business day before the final dividend payment date for the initial rate period for each series of MuniPreferred shares.

                                            SUBSEQUENT
SERIES                 FIRST AUCTION DATE   AUCTION DAY
------                 ------------------   -----------
M                                             Monday
T                                            Tuesday
W                                           Wednesday

The start date for subsequent rate periods normally will be the business day following the auction date unless the then-current rate period is a special rate period, or the day that normally would be the auction date or the first day of the subsequent rate period is not a business day.

Dividends and Rate Periods....   The table below shows the dividend rate for the
                                 initial rate period of the MuniPreferred
                                 offered in this prospectus. For subsequent rate
                                 periods, MuniPreferred shares will pay
                                 dividends based on a rate set at auctions,
                                 normally held weekly. The initial auction for
                                 Series T and Series W will not be held until
                                 after the Extended Initial Rate Period, which
                                 may be up to three years from the date of this
                                 offering. The rate set at auction will not
                                 exceed the Maximum Rate. See "Description of
                                 MuniPreferred Shares -- Dividends and Dividend
                                 Periods -- General."

The table below also shows the date from which dividends on the MuniPreferred shares will accumulate at the initial rate, the dividend payment date for the initial rate period and the number of days of the initial rate period for each series of MuniPreferred. For Series T and Series W with Extended Initial Rate Periods, the Fund will pay dividends based on the dividend rate for the initial rate period on March 1, 2004 and thereafter dividends for the initial rate period will be paid on the first business day of each month with the last dividend payment for the initial rate period on , 200 for Series and , 200 for Series .

For subsequent rate periods, other than special rate periods that may be specifically designated in advance, dividends will normally be paid weekly, on the day following the end of the subsequent rate period. The table below also shows the day on which dividends for subsequent rate periods will normally be paid. If such dividends are payable on a Monday or Tuesday and that day is not a business day, then your dividends will generally be paid on the first business day that falls after that day. If dividends are payable on a

4

Wednesday, Thursday or Friday and that day is not a business day, then your dividends generally will be paid on the first business day prior to that day. See "Description of MuniPreferred Shares -- Dividends and Dividend Periods -- General." The dividend payment date for any subsequent rate period that is a special rate period of more than 28 days will be set out in the notice designating a special rate period. See "Description of MuniPreferred Shares -- Dividends and Dividend Periods -- Designation of Special Rate Periods."

                                                                 NUMBER OF

* In the case of MuniPreferred Series T and Series W, dividends will be paid on , 2004, and on the first business day of each month thereafter with the last dividend payment date of the initial rate period on , 200 , and ,
200 , respectively.

Ratings.......................   Shares of each series of MuniPreferred will be
                                 issued a rating of "Aaa" from Moody's and "AAA"
                                 from S&P. Because the Fund is required to
                                 maintain at least one of these ratings, it must
                                 own portfolio securities of a sufficient value
                                 and with adequate credit quality to meet the
                                 rating agencies' guidelines. See "Description
                                 of MuniPreferred Shares -- Rating Agency
                                 Guidelines and Asset Coverage."


Redemption....................   Although the Fund will not ordinarily redeem
                                 MuniPreferred shares, it may be required to
                                 redeem shares if, for example, the Fund does
                                 not meet an asset coverage ratio required by
                                 law or in order to correct a failure to meet
                                 rating agency guidelines in a timely manner.
                                 The Fund may voluntarily redeem MuniPreferred
                                 shares is certain circumstances. See
                                 "Description of MuniPreferred
                                 Shares -- Redemption," and "-- Rating Agency
                                 Guidelines and Asset Coverage."

Liquidation Preference........   The liquidation preference of the shares of
                                 MuniPreferred will be $25,000 per share plus
                                 accumulated but unpaid dividends, if any,
                                 thereon. See "Description of MuniPreferred
                                 Shares -- Liquidation."

Federal Income Taxation.......   Because under normal circumstances the Fund
                                 will invest substantially all of its assets in
                                 municipal securities that pay interest exempt
                                 from regular federal income tax, the income you
                                 receive will ordinarily be similarly exempt. A
                                 portion of the income from the Fund may also be
                                 subject to the federal alternative minimum tax.
                                 Therefore, MuniPreferred shares may not be a
                                 suitable investment if you are subject to this
                                 tax or would become subject to such tax by
                                 investing in MuniPreferred shares. Taxable
                                 income and gain earned by the Fund will be
                                 allocated proportionately to holders of
                                 MuniPreferred shares and common shares, based
                                 on the percentage of total dividends paid to
                                 each class for that year. Accordingly,
                                        5


certain specified MuniPreferred dividends may be subject to regular federal income tax on income or gains attributed to the Fund. See "Federal Income Tax Matters." The Fund intends to notify shareholders, before any applicable auction for a rate period of 28 days or less, of the amount of any taxable income and gain for regular federal income tax purposes only, to be paid for the period relating to that auction. For longer periods, the Fund may notify shareholders of the foregoing information. In certain limited circumstances, the Fund will make payments to MuniPreferred shareholders to offset the federal income tax effects of the taxable distribution. For the initial rate period for Series T and Series W, which are Extended Initial Rate Periods, the Fund will not be able to notify shareholders of the amount of any taxable income and gain for regular federal income tax purposes to be paid during the initial rate period. The Fund will make payments to shareholders of Series T and Series W to offset the federal income tax effects of taxable distributions to Series T and Series W shareholders during the initial rate period. See "Description of MuniPreferred Shares -- Dividend and Dividend Periods -- Gross-Up Payments."

Voting Rights.................   The holders of the Fund's preferred shares,
                                 $.01 par value ("Preferred Shares"), including
                                 MuniPreferred, voting as a separate class, have
                                 the right to elect at least two trustees at all
                                 times and to elect a majority of the trustees
                                 in the event two full years' dividends on the
                                 Preferred Shares are unpaid. In each case, the
                                 remaining trustees will be elected by holders
                                 of common shares and Preferred Shares,
                                 including MuniPreferred, voting together as a
                                 single class. The holders of shares of
                                 Preferred Shares, including MuniPreferred, will
                                 vote as a separate class or classes on certain
                                 other matters as required under the Declaration
                                 of Trust, the Investment Company Act of 1940
                                 (the "1940 Act") and Massachusetts law. See
                                 "Description of MuniPreferred Shares -- Voting
                                 Rights" and "Certain Provisions in the
                                 Declaration of Trust."

FINANCIAL HIGHLIGHTS

Information contained in the table below under the headings "Per Share Operating Performance" and "Ratios/Supplemental Data" shows the unaudited operating performance of the Fund from the commencement of the Fund's investment operations on November 19, 2003 until December 29, 2003. Since the Fund commenced operations on November 19, 2003, the table covers less than six weeks of operations, during which a substantial portion of the Fund's assets were held in cash pending investment in municipal bonds that meet the Fund's investment objectives and policies. Accordingly, the information presented may not provide a meaningful picture of the Fund's operating performances.

                                                                   (UNAUDITED)

THE FUND'S INVESTMENTS

INVESTMENT OBJECTIVES

The Fund's primary investment objective is to provide high current income exempt from regular federal income tax. The Fund's secondary investment objective is to seek attractive total return consistent with its primary objective. Any capital appreciation realized by the Fund will generally result in the distribution of taxable capital gains to MuniPreferred shareholders. The Fund seeks to achieve its investment objectives by investing in municipal securities that Nuveen Advisory believes are underrated and undervalued. The Fund cannot assure you that it will achieve its investment objectives.

INVESTMENT PHILOSOPHY AND PROCESS

INVESTMENT PHILOSOPHY. Nuveen Advisory believes that the unique tax treatment of municipal securities and the structural characteristics in the municipal securities market create attractive opportunities to enhance the after-tax total return and diversification of the investment portfolios of taxable investors. Nuveen Advisory believes that these unique characteristics also present unique risks that may be managed to realize the benefits of the asset class.

After-Tax Income Potential: The primary source of total return from municipal securities comes from the tax-exempt income derived therefrom. Nuveen Advisory believes that, at acceptable levels of credit risk and maturity principal risk, the municipal securities market offers the potential for higher after-tax income when compared with other fixed income markets.

Managing Multi-Faceted Risks: Risk in the municipal securities market is derived from multiple sources, including credit risk at the issuer and sector levels, structural risks such as call risk, yield curve risk, and legislative and tax-related risks. Nuveen Advisory believes that managing these risks at both the individual security and Fund portfolio levels is an important element of realizing the after-tax income and total return potential of the asset class.

Opportunities for Diversification: As of December 31, 2002, the municipal securities market aggregated approximately $1.76 trillion, with over 50,000 issuers, and a wide array of financing purposes, security terms, offering structures and credit quality. Nuveen Advisory believes that the size and depth of the municipal securities market may facilitate the creation of a diversified portfolio that reduces exposure to the risks of individual issuers and may lower correlations to other credit and market risks within an investor's overall portfolio.

Market Inefficiencies: Nuveen Advisory believes that the scale and intricacy of the municipal securities market often results in pricing anomalies and other inefficiencies that can be identified and capitalized on through trading strategies.

INVESTMENT PROCESS. Nuveen Advisory believes that a bottom-up, value-oriented investment strategy that seeks to identify underrated and undervalued securities and sectors is positioned to capture the opportunities inherent in the municipal securities market and potentially outperform the general municipal securities market over time. The primary elements of Nuveen Advisory's investment process are:

Credit Analysis and Surveillance: Nuveen Advisory focuses on bottom-up, fundamental analysis of municipal securities issuers. Analysts screen each sector for issuers that meet the fundamental tests of creditworthiness and favor those securities with demonstrable growth potential, solid coverage of debt service and a priority lien on hard assets, dedicated revenue streams or tax resources. As part of Nuveen Advisory's overall risk management process, analysts actively monitor the credit quality of portfolio holdings.

Sector Analysis: Organized by sector, analysts continually assess the key issues and trends affecting each sector in order to maintain a sector outlook. Evaluating such factors as historical default rates and average credit spreads within each sector, analysts provide top-down analysis that supports decisions to overweight or underweight a given sector in a portfolio.

10

Diversification: Nuveen Advisory seeks to invest in a large number of sectors, states and specific issuers in order to help insulate a portfolio from events that affect any individual industry, geographic location or credit. Portfolio managers normally seek to limit exposure to individual credits over the long-term. Portfolio managers also seek to diversify other portfolio level risks, including exposure to calls, and to manage a portfolio's interest rate sensitivity within tolerance bands relative to the relevant benchmark.

Trading Strategies: Through its trading strategies, Nuveen Advisory seeks to enhance portfolio value by trading to take advantage of inefficiencies found in the municipal market. This may entail selling issues Nuveen Advisory deems to be overvalued and purchasing issues Nuveen Advisory considers to be undervalued.

Sell Discipline: Nuveen Advisory generally sells securities when it (i) determines a security has become overvalued or over-rated, (ii) identifies credit deterioration, or (iii) modifies a portfolio strategy, such as sector allocation. Nuveen Advisory may also sell securities when such securities exceed the portfolio's diversification targets.

INVESTMENT POLICIES

Under normal circumstances, the Fund will invest its Managed Assets in a portfolio of municipal securities that pay interest that is exempt from regular federal income tax. It is a fundamental policy of the Fund that its investment in municipal securities paying interest that is exempt from regular federal income tax will, under normal circumstances, comprise at least 80% of the Fund's Managed Assets. Under normal circumstances, the Fund expects to be fully invested (at least 95% of its Managed Assets) in such tax-exempt municipal securities. Up to 30% of the Fund's Managed Assets may be invested in municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to individuals. For a discussion of how the federal alternative minimum tax may affect shareholders, see "Federal Income Tax Matters."

- The Fund will invest at least 50% of its Managed Assets in investment grade quality municipal securities. A security is considered investment grade quality if it is rated within the four highest grades (Baa or BBB or better by Moody's, S&P or Fitch) by all NRSROs that rate such security, or if it is unrated but judged to be of comparable quality by Nuveen Advisory.

- The Fund may invest up to 50% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade. Below investment grade quality municipal securities include those municipal securities that are rated investment grade by one or more NRSROs but rated below investment grade by at least one NRSRO. No more than 5% of the Fund's Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Advisory. This means that the Fund may invest in municipal securities that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition (such securities are commonly referred to as distressed securities).

- The Fund anticipates that, upon the full investment of the net proceeds from this offering (which is expected to occur within two to three months following the closing of this offering), it will have invested approximately 55% to 65% of its Managed Assets in investment grade municipal securities and approximately 35% to 45% of its Managed Assets in below investment grade municipal securities. The relative percentages of the value of the Fund's Managed Assets attributable to investment grade municipal securities and to below investment grade municipal securities could change over time as a result of rebalancing the Fund's assets by Nuveen Advisory, market value fluctuations and other events.

Municipal securities of below investment grade quality are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal and are commonly referred to as junk bonds. The foregoing credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a rating agency downgrades its assessment of the credit characteristics of a particular issue. In determining whether to retain or sell such a security, Nuveen Advisory

11

may consider such factors as Nuveen Advisory's assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. A general description of Moody's, S&P's and Fitch's ratings of municipal securities is set forth in Appendix A to the Statement of Additional Information. The Fund may also invest in securities of other open-or closed-end investment companies that invest primarily in municipal securities of the types in which the Fund may invest directly. See "-- Other Investment Companies" and "-- Initial Portfolio Composition."

The Fund may purchase municipal securities that are additionally secured by insurance, bank credit agreements, or escrow accounts. The credit quality of companies which provide such credit enhancements will affect the value of those securities. Although the insurance feature reduces certain financial risks, the premiums for insurance and the higher market price paid for insured obligations may reduce the Fund's income. The Fund may use any insurer, regardless of its rating. A municipal security will be deemed to have the rating of its insurer. The insurance feature does not guarantee the market value of the insured obligations or the net asset value of the common shares.

The Fund presently intends to limit its investment in tobacco settlement bonds to no more than 10% of its Managed Assets. In addition, the Fund will not invest in inverse floating rate securities, which are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and which represent a leveraged investment in an underlying municipal security.

Upon Nuveen Advisory's recommendation, during temporary defensive periods and in order to keep the Fund's cash fully invested, including the period during which the net proceeds of the offering of common shares or MuniPreferred shares are being invested, the Fund may deviate from its investment objectives and invest up to 100% of its net assets in short-term investments including high quality, short-term securities that may be either tax-exempt or taxable. The Fund intends to invest in taxable short-term investments only in the event that suitable tax-exempt short-term investments are not available at reasonable prices and yields. Investment in taxable short-term investments would result in a portion of your dividends being subject to regular federal income taxes. For more information, see the Statement of Additional Information.

The Fund cannot change its investment objectives without the approval of the holders of a "majority of the outstanding" common shares and, if issued, MuniPreferred shares voting together as a single class, and of the holders of a "majority of the outstanding" MuniPreferred shares voting as a separate class. When used with respect to particular shares of the Fund, a "majority of the outstanding" shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy, or (ii) more than 50% of the shares, whichever is less. See "Description of MuniPreferred Shares -- Voting Rights" for additional information with respect to the voting rights of holders of MuniPreferred shares.

If you are, or as a result of investment in the Fund would become, subject to the federal alternative minimum tax, the Fund may not be a suitable investment for you because the Fund expects that a substantial portion of its investments will pay interest that is taxable under the federal alternative minimum tax. Special rules apply to corporate holders. In addition, distributions of net capital gain will be subject to capital gains taxes. See "Federal Income Tax Matters."

MUNICIPAL SECURITIES

Municipal securities are either general obligation or revenue bonds and typically are issued to finance public projects (such as roads or public buildings), to pay general operating expenses, or to refinance outstanding debt. Municipal securities may also be issued for private activities, such as housing, medical and educational facility construction, or for privately owned industrial development and pollution control projects. General obligation bonds are backed by the full faith and credit, or taxing authority, of the issuer and may be repaid from any revenue source; revenue bonds may be repaid only from the revenues of a specific facility or source. The Fund may also purchase municipal securities that represent lease obligations, municipal notes, pre-refunded municipal securities, private activity bonds, tender option bonds and other forms of municipal securities.

12

The municipal securities in which the Fund will invest are generally issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico and Guam), and pay interest that, in the opinion of bond counsel to the issuer (or on the basis of other authority believed by Nuveen Advisory to be reliable), is exempt from regular federal income tax, although the interest may be subject to the federal alternative minimum tax.

The yields on municipal securities depend on a variety of factors, including prevailing interest rates and the condition of the general money market and the municipal bond market, the size of a particular offering, the maturity of the obligation and the rating of the issue. The market value of municipal securities will vary with changes in interest rate levels and as a result of changing evaluations of the ability of their issuers to meet interest and principal payments.

The Fund will primarily invest in municipal securities with long-term maturities in order to maintain a weighted average maturity of 15 to 30 years, but the weighted average maturity of obligations held by the Fund may be shorter, depending on market conditions. Likewise, the Fund anticipates that its duration following the invest up period will be in the range of 8 to 10 years, depending on market conditions. In comparison to maturity (which is the date on which a debt instrument ceases and the issuer is obligated to repay the principal amount), duration is a measure of the price volatility of a debt instrument as a result of changes in market rates of interest, based on the weighted average timing of the instrument's expected principal and interest payments. Duration differs from maturity in that it considers a security's yield, coupon payments, principal payments and call features in addition to the amount of time until the security finally matures. As the value of a security changes over time, so will its duration. Prices of securities with longer durations tend to be more sensitive to interest rate changes than securities with shorter durations. In general, a portfolio of securities with a longer duration can be expected to be more sensitive to interest rate changes than a portfolio with a shorter duration.

Municipal Leases and Certificates of Participation. The Fund also may purchase municipal securities that represent lease obligations and certificates of participation in such leases. These carry special risks because the issuer of the securities may not be obligated to appropriate money annually to make payments under the lease. A municipal lease is an obligation in the form of a lease or installment purchase which is issued by a state or local government to acquire equipment and facilities. Income from such obligations is generally exempt from state and local taxes in the state of issuance. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of "non-appropriation" clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment or facilities. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and result in a delay in recovering, or the failure to recover fully, the Fund's original investment. To the extent that the Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. In order to reduce this risk, the Fund will only purchase municipal securities representing lease obligations where Nuveen Advisory believes the issuer has a strong incentive to continue making appropriations until maturity.

A certificate of participation represents an undivided interest in an unmanaged pool of municipal leases, an installment purchase agreement or other instruments. The certificates are typically issued by a municipal agency, a trust or other entity that has received an assignment of the payments to be made by the state or political subdivision under such leases or installment purchase agreements. Such certificates provide the Fund with the right to a pro rata undivided interest in the underlying municipal securities. In addition, such participations generally provide the Fund with the right to demand payment, on not more than seven days'

13

notice, of all or any part of the Fund's participation interest in the underlying municipal securities, plus accrued interest.

Municipal Notes. Municipal securities in the form of notes generally are used to provide for short-term capital needs, in anticipation of an issuer's receipt of other revenues or financing, and typically have maturities of up to three years. Such instruments may include tax anticipation notes, revenue anticipation notes, bond anticipation notes, tax and revenue anticipation notes and construction loan notes. Tax anticipation notes are issued to finance the working capital needs of governments. Generally, they are issued in anticipation of various tax revenues, such as income, sales, property, use and business taxes, and are payable from these specific future taxes. Revenue anticipation notes are issued in expectation of receipt of other kinds of revenue, such as federal revenues available under federal revenue sharing programs. Bond anticipation notes are issued to provide interim financing until long- term bond financing can be arranged. In most cases, the long-term bonds then provide the funds needed for repayment of the bond anticipation notes. Tax and revenue anticipation notes combine the funding sources of both tax anticipation notes and revenue anticipation notes. Construction loan notes are sold to provide construction financing. Mortgage notes insured by the Federal Housing Authority secure these notes; however, the proceeds from the insurance may be less than the economic equivalent of the payment of principal and interest on the mortgage note if there has been a default. The anticipated revenues from taxes, grants or bond financing generally secure the obligations of an issuer of municipal notes. An investment in such instruments, however, presents a risk that the anticipated revenues will not be received or that such revenues will be insufficient to satisfy the issuer's payment obligations under the notes or that refinancing will be otherwise unavailable.

Pre-Refunded Municipal Securities. The principal of and interest on pre-refunded municipal securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as the pre-refunded municipal securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for the pre-refunded municipal securities. However, except for a change in the revenue source from which principal and interest payments are made, the pre-refunded municipal securities remain outstanding on their original terms until they mature or are redeemed by the issuer.

Private Activity Bonds. Private activity bonds, formerly referred to as industrial development bonds, are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues. The Fund's distributions of its interest income from private activity bonds may subject certain investors to the federal alternative minimum tax.

Tender Option Bonds. A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term, tax-exempt rates. The bond is typically issued with the agreement of a third party, such as a bank, broker-dealer or other financial institution, which grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the bond's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, an institution will not be obligated to accept tendered bonds in the event of certain defaults or a significant downgrade in the credit rating assigned to the issuer of the bond. The Fund intends to invest in tender option bonds the interest

14

on which will, in the opinion of bond counsel, counsel for the issuer of interests therein or counsel selected by Nuveen Advisory, be exempt from regular federal income tax. However, because there can be no assurance that the Internal Revenue Service (the "IRS") will agree with such counsel's opinion in any particular case, there is a risk that the Fund will not be considered the owner of such tender option bonds and thus will not be entitled to treat such interest as exempt from such tax. Additionally, the federal income tax treatment of certain other aspects of these investments, including the proper tax treatment of tender option bonds and the associated fees in relation to various regulated investment company tax provisions, is unclear. The Fund intends to manage its portfolio in a manner designed to eliminate or minimize any adverse impact from the tax rules applicable to these investments.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure developments to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

When-Issued and Delayed Delivery Transactions. The Fund may buy and sell municipal securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15 to 45 days of the trade date. This type of transaction may involve an element of risk because no interest accrues on the bonds prior to settlement and, because bonds are subject to market fluctuations, the value of the bonds at time of delivery may be less (or more) than cost. A separate account of the Fund will be established with its custodian consisting of cash, cash equivalents, or liquid securities having a market value at all times at least equal to the amount of the commitment.

Zero Coupon Bonds. A zero coupon bond is a bond that does not pay interest either for the entire life of the obligation or for an initial period after the issuance of the obligation. When held to its maturity, its return comes from the difference between the purchase price and its maturity value. A zero coupon bond is normally issued and traded at a deep discount from face value. Zero coupon bonds allow an issuer to avoid or delay the need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest currently or in cash. The Fund would be required to distribute the income on any of these instruments as it accrues, even though the Fund will not receive all of the income on a current basis or in cash. Thus, the Fund may have to sell other investments, including when it may not be advisable to do so, to make income distributions to its shareholders.

Structured Notes. The Fund may utilize structured notes and similar instruments for investment purposes and also for hedging purposes. Structured notes are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an "embedded index"), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but not ordinarily below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending upon a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index or indices or other assets. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

OTHER INVESTMENT COMPANIES

The Fund may invest up to 10% of its Managed Assets in securities of other open- or closed-end investment companies that invest primarily in municipal securities of the types in which the Fund may invest directly. In addition, the Fund may invest a portion of its Managed Assets in pooled investment vehicles (other than investment companies) that invest primarily in municipal securities of the types in which the Fund may invest directly. The Fund generally expects that it may invest in other investment companies and/or other pooled investment vehicles either during periods when it has large amounts of uninvested cash, such as the period shortly after the Fund receives the proceeds of the offering of its common shares or MuniPreferred shares, or during periods when there is a shortage of attractive, high-yielding municipal securities available in the market. As a stockholder in an investment company, the Fund will bear its ratable share of that investment company's expenses, and would remain subject to payment of the Fund's advisory and administrative fees with respect to assets so invested. Common shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. Nuveen Advisory will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available municipal security investments.

In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. As described in the section entitled "Risk Factors," the net asset value and market value of leveraged shares will be more volatile and the yield to common shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

INITIAL PORTFOLIO COMPOSITION

If current market conditions persist, the Fund expects that approximately 55% to 65% of its initial portfolio will consist of investment grade quality municipal securities, rated as such at the time of investment. A security is considered investment grade quality if it is rated within the four highest grades by all NRSROs that rate such security, or if it is unrated but judged to be of comparable quality by Nuveen Advisory. The Fund also expects that approximately 35% to 45% of its initial portfolio will consist of below investment grade quality municipal securities, rated as such at the time of investment or unrated but judged to be of comparable quality by Nuveen Advisory. In addition, the Fund anticipates that the initial average credit quality of the portfolio will be BBB, including securities that are not rated by any NRSROs but have ratings assigned to them by Nuveen Advisory for internal compliance purposes. As previously noted, the Fund anticipates that its duration following the invest up period will be in the range of 8 to 10 years, depending on market conditions. See the Statement of Additional Information under "Other Investment Policies and Techniques -- Portfolio Trading and Turnover Rate." See "-- Investment Policies."

RISK FACTORS

Risk is inherent in all investing. Investing in any investment company security involves risk, including the risk that you may receive little or no return on your investment or even that you may lose part or all of your investment. Therefore, before investing you should consider carefully the following risks that you assume when you invest in MuniPreferred shares.

Limited Operating History. The Fund is a recently organized, diversified, closed-end management investment company and has a limited operating history.

Interest Rate Risk (and its impact on the value of the Fund's investments). The Fund issues MuniPreferred shares, which pay dividends based on short- and intermediate-term interest rates, and uses the proceeds to buy municipal bonds, which pay interest based on long-term yields. Long-term municipal bond yields are typically, although not always, higher than short- and intermediate-term interest rates. Long-term, intermediate-term and short-term interest rates may fluctuate. If short- or intermediate-term interest rates rise, MuniPreferred rates may rise so that the amount of dividends paid to MuniPreferred shareholders exceeds the income from the portfolio securities purchased with the proceeds from the sale of MuniPreferred shares. Because income from the Fund's entire investment portfolio (not just the portion of the portfolio purchased with the proceeds of the MuniPreferred share offering) is available to pay MuniPreferred dividends, however, MuniPreferred dividend rates would need to greatly exceed the Fund's net portfolio income before the Fund's ability to pay MuniPreferred dividends would be jeopardized. If long-term rates rise, the value of the Fund's investment portfolio will decline, reducing the amount of assets serving as asset coverage for the MuniPreferred shares.

Auction Risk. You may not be able to sell your MuniPreferred shares at an auction if the auction fails; that is, if there are more MuniPreferred shares offered for sale than there are buyers for those shares. Also, if you place hold orders (orders to retain MuniPreferred shares) at an auction only at a specified rate, and that bid rate exceeds the rate set at the auction, you will not retain your MuniPreferred shares. Finally, if you buy shares or elect to retain shares without specifying a rate below which you would not wish to continue to hold those shares, and the auction sets a below-market rate, you may receive a lower rate of return on your shares than the market rate. See "Description of MuniPreferred Shares" and "The Auction -- Auction Procedures."

Secondary Market Risk (and the possible impact of Interest Rate Risk on the value of MuniPreferred shares during Extended Initial Rate Periods and special rate periods). If you try to sell your MuniPreferred shares between auctions, you may not be able to sell any or all of your shares, or you may not be able to sell them for $25,000 per share or $25,000 per share plus accumulated dividends. In the case of Extended Initial Rate Periods for Series T and Series W MuniPreferred, or if the Fund has designated a subsequent rate period for a series as a special rate period (a rate period of more than 7 days), changes in market interest rates could adversely affect the price you would receive if you sold your shares in the secondary market. If market interest rates for tax-exempt securities having similar credit quality to the MuniPreferred shares, and maturities equivalent to the period remaining until the end of the Extended Initial Rate Period (or subsequent special rate period), increase so as to exceed the dividend rate for that rate period, the amount for which the MuniPreferred shares could be sold in the secondary market (assuming there is a market for the shares) will tend to fall, and will likely be less than $25,000 per share. Broker-dealers that maintain a secondary trading market for MuniPreferred shares, if any, are not required to maintain this market, and the Fund is not required to redeem shares either if an auction or an attempted secondary market sale fails because of a lack of buyers. MuniPreferred shares are not registered on a stock exchange or the NASDAQ stock market. If you sell your MuniPreferred shares to a broker-dealer between auctions, you may receive less than the price you paid for them, especially when market interest rates have risen since the last auction or risen higher than the dividend rate on a series within a rate period longer than 7 days, including the Extended Initial Rate Period of Series T and Series W.

Ratings and Asset Coverage Risk. While Moody's and S&P assign ratings of "Aaa" and "AAA", respectively, to MuniPreferred shares, the ratings do not eliminate or necessarily mitigate the risks of investing in MuniPreferred shares. A rating agency could downgrade MuniPreferred shares, which may make your shares less liquid at an auction or in the secondary market. If a rating agency downgrades MuniPreferred

17

shares, the Fund may alter its portfolio or redeem MuniPreferred shares. The Fund may voluntarily redeem MuniPreferred shares under certain circumstances. See "Description of MuniPreferred Shares -- Rating Agency Guidelines and Asset Coverage" for a description of the asset maintenance tests the Fund must meet.

Credit and Below Investment Grade Risk. Credit risk is the risk that one or more municipal securities in the Fund's portfolio will decline in price, or the issuer thereof will fail to pay interest or principal when due, because the issuer of the security experiences a decline in its financial status. In general, lower-rated municipal securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative impact on the Fund's net asset value or dividends. The Fund may invest up to 50% of its Managed Assets in municipal securities that are rated below investment grade at the time of investment or that are unrated but judged to be of comparable quality by Nuveen Advisory. No more than 5% of the Fund's Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Advisory. This means that the Fund may invest in municipal securities that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition (such securities are commonly referred to as distressed securities). Municipal securities of below investment grade quality, commonly referred to as junk bonds, are regarded as having predominately speculative characteristics with respect to capacity to pay interest and repay principal when due, and are susceptible to default or decline in market value due to adverse economic and business developments. The market values for municipal securities of below investment grade quality tend to be volatile, and these securities are less liquid than investment grade municipal securities. For these reasons, an investment in the Fund is subject to the following specific risks:

- increased price sensitivity resulting from changing interest rates and/or a deteriorating economic environment;

- greater risk of loss due to default or declining credit quality;

- adverse issuer specific events that are more likely to render the issuer unable to make interest and/or principal payments; and

- the possibility that a negative perception of the below investment grade market develops, resulting in the price and liquidity of below investment grade securities becoming depressed, and this negative perception could last for a significant period of time.

Adverse changes in economic conditions are more likely to lead to a weakened capacity of a below investment grade issuer to make principal payments and interest payments compared to an investment grade issuer. The principal amount of below investment grade securities outstanding has proliferated in the past decade as an increasing number of issuers have used below investment grade securities for financing. An economic downturn could severely affect the ability of highly leveraged issuers to service their debt obligations or to repay their obligations upon maturity. If the national economy enters into a recessionary phase during 2004, potentially decreasing the tax and other revenue of municipal issuers, or interest rates rise sharply, increasing the interest cost on variable rate instruments and negatively impacting economic activity, the number of defaults by below investment grade municipal issuers is likely to increase. Similarly, down-turns in profitability in specific industries could adversely affect private activity bonds. The market values of lower quality debt securities tend to reflect individual developments of the issuer to a greater extent than do higher quality securities, which react primarily to fluctuations in the general level of interest rates. Factors having an adverse impact on the market value of lower quality securities may have an adverse impact on the Fund's net asset value and the market value of its common shares. In addition, the Fund may incur additional expenses to the extent it is required to seek recovery upon a default in payment of principal or interest on its portfolio holdings. In certain circumstances, the Fund may be required to foreclose on an issuer's assets and take possession of its property or operations. In such circumstances, the Fund would incur additional costs in disposing of such assets and potential liabilities from operating any business acquired.

The secondary market for below investment grade securities may not be as liquid as the secondary market for more highly rated securities, a factor that may have an adverse effect on the Fund's ability to dispose of a particular security. There are fewer dealers in the market for below investment grade municipal securities than

18

the market for investment grade municipal securities. The prices quoted by different dealers for below investment grade municipal securities may vary significantly, and the spread between the bid and ask price is generally much larger for below investment grade municipal securities than for higher quality instruments. Under adverse market or economic conditions, the secondary market for below investment grade securities could contract further, independent of any specific adverse changes in the condition of a particular issuer, and these instruments may become illiquid. As a result, the Fund could find it more difficult to sell these securities or may be able to sell the securities only at prices lower than if such securities were widely traded. Prices realized upon the sale of such lower rated or unrated securities, under these circumstances, may be less than the prices used in calculating the Fund's net asset value.

Issuers of such below investment grade securities are highly leveraged and may not have available to them more traditional methods of financing. Therefore, the risk associated with acquiring the securities of such issuers generally is greater than is the case with higher rated securities. For example, during an economic downturn or a sustained period of rising interest rates, highly leveraged issuers of below investment grade securities may experience financial stress. During such periods, such issuers may not have sufficient revenues to meet their interest payment obligations. The issuer's ability to service its debt obligations also may be adversely affected by specific developments, the issuer's inability to meet specific projected forecasts or the unavailability of additional financing. The risk of loss from default by the issuer is significantly greater for the holders of below investment grade securities because such securities are generally unsecured and are often subordinated to other creditors of the issuer. Prices and yields of below investment grade securities will fluctuate over time and, during periods of economic uncertainty, volatility of below investment grade securities may adversely affect the Fund's net asset value. In addition, investments in below investment grade zero coupon bonds rather than income-bearing below investment grade securities, may be more speculative and may be subject to greater fluctuations in value due to changes in interest rates.

The Fund may invest in distressed securities, which are securities issued by companies that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition by the Fund. The issuers of such securities may be in transition, out of favor, financially leveraged or troubled, or potentially troubled, and may be or have recently been involved in major strategic actions, restructurings, bankruptcy, reorganization or liquidation. These characteristics of these companies can cause their securities to be particularly risky, although they also may offer the potential for high returns. These companies' securities may be considered speculative, and the ability of the companies to pay their debts on schedule could be affected by adverse interest rate movements, changes in the general economic climate, economic factors affecting a particular industry or specific developments within the companies. Distressed securities frequently do not produce income while they are outstanding and may require the Fund to bear certain extraordinary expenses in order to protect and recover its investment.

Investments in lower rated or unrated securities may present special tax issues for the Fund to the extent that the issuers of these securities default on their obligations pertaining thereto, and the federal income tax consequences to the Fund as a holder of such distressed securities may not be clear.

Municipal Securities Market Risk. Investing in the municipal securities market involves certain risks. The amount of public information available about the municipal securities in the Fund's portfolio is generally less than that for corporate equities or bonds, and the investment performance of the Fund may therefore be more dependent on the analytical abilities of Nuveen Advisory than if the Fund were a stock fund or taxable bond fund. The secondary market for municipal securities, particularly the below investment grade bonds in which the Fund may invest, also tends to be less well-developed or liquid than many other securities markets, which may adversely affect the Fund's ability to sell its municipal securities at attractive prices or at prices approximating those at which the Fund currently values them.

The ability of municipal issuers to make timely payments of interest and principal may be diminished during general economic downturns and as governmental cost burdens are reallocated among federal, state and local governments. In addition, laws enacted in the future by Congress or state legislatures or referenda could extend the time for payment of principal and/or interest, or impose other constraints on enforcement of such obligations, or on the ability of municipalities to levy taxes. Issuers of municipal securities might seek

19

protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, the Fund could experience delays in collecting principal and interest and the Fund may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in the payment of interest or repayment of principal, or both, the Fund may take possession of and manage the assets securing the issuer's obligations on such securities, which may increase the Fund's operating expenses. Any income derived from the Fund's ownership or operation of such assets may not be tax-exempt.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund's portfolio will decline if and when the Fund invests the proceeds from matured, traded or called bonds at market interest rates that are below the portfolio's current earnings rate. A decline in income could affect the common shares' market price or their overall returns.

Tax Risk. The value of the Fund's investments and its net asset value may be adversely affected by changes in tax rates and policies. Because interest income from municipal securities is normally not subject to regular federal income taxation, the attractiveness of municipal securities in relation to other investment alternatives is affected by changes in federal income tax rates or changes in the tax-exempt status of interest income from municipal securities. Any proposed or actual changes in such rates or exempt status, therefore, can significantly affect the demand for and supply, liquidity and marketability of municipal securities. This could in turn affect the Fund's net asset value and ability to acquire and dispose of municipal securities at desirable yield and price levels. Additionally, the Fund is not a suitable investment for individual retirement accounts, for other tax-exempt or tax-deferred accounts or for investors who are not sensitive to the federal income tax consequences of their investments.

Inflation Risk. Inflation risk is the risk that the value of assets or income from investment will be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the dividends paid to MuniPreferred shareholders can decline.

Sector and Industry Risk. The Fund may invest in municipal securities that are collateralized by the proceeds from class action or other litigation against the tobacco industry. Payment by tobacco industry participants of such proceeds is spread over several years, and the collection and distribution of such proceeds to the issuers of municipal securities is dependent upon the financial health of such tobacco industry participants, which cannot be assured. Additional litigation, government regulation or prohibition on the sales of tobacco products, or the seeking of protection under the bankruptcy laws by companies in the tobacco industry, could adversely affect the tobacco industry which, in turn, could have an adverse affect on tobacco-related municipal securities. The Fund presently intends to limit its investment in tobacco settlement bonds to no more than 10% of the Fund's Managed Assets.

Subject to rating agency guidelines, the Fund may invest a significant portion of its Managed Assets in broad segments of the municipal securities market, such as revenue obligations of hospitals and other health care facilities, special taxing districts, securities issued to finance charter schools and other private educational facilities, municipal utility securities, industrial development bonds, and other private activity bonds. Subject to the availability of suitable investment opportunities, Nuveen Advisory will attempt to minimize the sensitivity of the Fund's portfolio to credit and other risks associated with a particular sector or industry. However, if the Fund invests a significant portion of its Managed Assets in the segments noted above, the Fund will be more susceptible to economic, business, political, regulatory and other developments generally affecting issuers in such segments of the municipal securities market. To the extent that the Fund focuses its Managed Assets in the hospital and healthcare facilities sector, the Fund will be subject to risks associated with such sector, including adverse government regulation and reduction in reimbursement rates, as well as government approval of products and services and intense competition. Securities issued with respect to special taxing districts will be subject to various risks, including real-estate development related risks and taxpayer concentration risk. Further, the fees, special taxes or tax allocations and other revenues established to secure the obligations of securities issued with respect to special taxing districts are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. Securities issued to finance charter schools and other private educational facilities will be subject to various risks, including the reversal of legislation authorizing or funding charter

20

schools, the failure to renew or secure a charter, the failure of a funding entity to appropriate necessary funds and competition from alternatives such as voucher programs. Issuers of municipal utility securities can be significantly affected by government regulation, financing difficulties, supply and demand of services or fuel and natural resource conservation. The transportation sector, including airports, airlines, ports and other transportation facilities, can be significantly affected by changes in the economy, fuel prices, labor relations, insurance costs and government regulation.

Special Risks Related to Certain Municipal Obligations. The Fund may invest in municipal leases and certificates of participation in such leases. Municipal leases and certificates of participation involve special risks not normally associated with general obligations or revenue bonds. Leases and installment purchase or conditional sale contracts (which normally provide for title to the leased asset to pass eventually to the governmental issuer) have evolved as a means for governmental issuers to acquire property and equipment without meeting the constitutional and statutory requirements for the issuance of debt. The debt issuance limitations are deemed to be inapplicable because of the inclusion in many leases or contracts of "non-appropriation" clauses that relieve the governmental issuer of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body on a yearly or other periodic basis. In addition, such leases or contracts may be subject to the temporary abatement of payments in the event the governmental issuer is prevented from maintaining occupancy of the leased premises or utilizing the leased equipment. Although the obligations may be secured by the leased equipment or facilities, the disposition of the property in the event of non-appropriation or foreclosure might prove difficult, time consuming and costly, and may result in a delay in recovering or the failure to fully recover the Fund's original investment. In the event of non-appropriation, the issuer would be in default and taking ownership of the assets may be a remedy available to the Fund, although the Fund does not anticipate that such a remedy would normally be pursued. To the extent that the Fund invests in unrated municipal leases or participates in such leases, the credit quality rating and risk of cancellation of such unrated leases will be monitored on an ongoing basis. Certificates of participation, which represent interests in unmanaged pools of municipal leases or installment contracts, involve the same risks as the underlying municipal leases. In addition, the Fund may be dependent upon the municipal authority issuing the certificates of participation to exercise remedies with respect to the underlying securities. Certificates of participation also entail a risk of default or bankruptcy, both of the issuer of the municipal lease and also the municipal agency issuing the certificate of participation.

Market Disruption Risk. Certain events have a disruptive effect on the securities markets, such as terrorist attacks (including the terrorist attacks in the U.S. on September 11, 2001), war and other geopolitical events. The Fund cannot predict the effects of similar events in the future on the U.S. economy. Below investment grade securities tend to be more volatile than higher rated securities so that these events and any actions resulting from them may have a greater impact on the prices and volatility of below investment grade securities than on higher rated securities.

Certain Affiliations. Certain broker-dealers may be considered to be affiliated persons of the Fund, Nuveen Advisory and/or Nuveen. Absent an exemption from the Securities and Exchange Commission or other regulatory relief, the Fund is generally precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase securities being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. This could limit the Fund's ability to engage in securities transactions and take advantage of market opportunities.

HOW THE FUND MANAGES RISK

INVESTMENT LIMITATIONS

The Fund has adopted certain investment limitations designed to limit investment risk and maintain portfolio diversification. These limitations are fundamental and may not be changed without the approval of the holders of a "majority of the outstanding" common shares and MuniPreferred shares voting together as a single class, and the approval of the holders of a "majority of the outstanding" MuniPreferred shares voting as

21

a separate class. When used with respect to particular shares of the Fund, a "majority of the outstanding" shares means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy, or (ii) more than 50% of the shares, whichever is less.

The Fund is subject to guidelines which are more limiting than the investment restrictions set forth above in order to obtain and maintain ratings from Moody's or S&P on the MuniPreferred shares. See "Investment Objectives" in the Statement of Additional Information for information about these guidelines and a complete list of the fundamental and non-fundamental investment policies of the Fund.

MANAGEMENT OF INVESTMENT PORTFOLIO AND CAPITAL STRUCTURE TO LIMIT LEVERAGE RISK

The Fund may take certain actions if short- or intermediate-term interest rates increase or market conditions otherwise change (or the Fund anticipates such an increase or change) and the Fund's leverage begins (or is expected) to adversely affect common shareholders. In order to attempt to offset such a negative impact of leverage on common shareholders, the Fund may shorten the average maturity of its investment portfolio (by investing in short-term, high quality securities) or may extend the maturity of outstanding MuniPreferred shares. The Fund may also attempt to reduce the leverage by redeeming or otherwise purchasing MuniPreferred shares. The success of any such attempt to limit leverage risk depends on Nuveen Advisory's ability to accurately predict interest rate or other market changes. Because of the difficulty of making such predictions, the Fund may never attempt to manage its capital structure in the manner described above.

If market conditions suggest that additional leverage would be beneficial, the Fund may sell previously unissued MuniPreferred shares or MuniPreferred shares that the Fund previously issued but later repurchased.

NO INVERSE FLOATING RATE SECURITIES

The Fund may not invest in inverse floating rate securities, which are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and which represent a leveraged investment in an underlying municipal security. This restriction is a non-fundamental policy of the Fund that may be changed by vote of the Fund's Board of Trustees.

HEDGING STRATEGIES

The Fund may use various investment strategies designed to limit the risk of bond price fluctuations and to preserve capital. These hedging strategies include using credit default swaps, interest-rate swaps on taxable tax-exempt indices, forward starting rate swaps and options on interest rate swaps, financial futures contracts, options on financial futures or options based on either an index of long-term municipal securities or on taxable debt securities whose prices, in the opinion of Nuveen Advisory, correlate with the prices of the Fund's investments. These hedging strategies may generate taxable income.

MANAGEMENT OF THE FUND

TRUSTEES AND OFFICERS

The Board of Trustees is responsible for the management of the Fund, including supervision of the duties performed by Nuveen Advisory. The names and business addresses of the trustees and officers of the Fund and their principal occupations and other affiliations during the past five years are set forth under "Management of the Fund" in the Statement of Additional Information.

INVESTMENT ADVISER

Nuveen Advisory, 333 West Wacker Drive, Chicago, Illinois 60606, serves as the investment adviser to the Fund. In this capacity, Nuveen Advisory is responsible for the selection and on-going monitoring of the municipal securities in the Fund's investment portfolio, managing the Fund's business affairs and providing certain clerical, bookkeeping and administrative services. Nuveen Advisory serves as investment adviser to

22

investment portfolios with more than $45 billion in assets under management. See the Statement of Additional Information under "Investment Adviser."

Nuveen Advisory is responsible for execution of specific investment strategies and day-to-day investment operations. Nuveen Advisory manages the Fund using a team of analysts and portfolio managers that focus on a specific group of funds. John V. Miller is the portfolio manager of the Fund and will provide daily oversight for, and execution of, the Fund's investment activities. He became a Vice President of Nuveen Advisory in 2003. Prior thereto, he was a credit analyst with Nuveen (since 1996). Mr. Miller currently manages investments for three Nuveen-sponsored investment companies.

Nuveen Advisory is a wholly owned subsidiary of Nuveen Investments, Inc. Founded in 1898, Nuveen through its various affiliates manages $90 billion in assets for clients in separate accounts, registered investment companies, and other collective investment vehicles as of September 30, 2003. Nuveen Investments, Inc. is a publicly traded company and is a majority-owned subsidiary of The St. Paul Companies, Inc. ("St. Paul"), a publicly-traded company which is principally engaged in providing property-liability insurance through subsidiaries. According to data from Thompson Wealth Management, Nuveen Investments, Inc. is the leading sponsor of municipal closed-end exchange-traded bond funds as measured by number of funds (97) and fund assets under management ($35 billion) as of September 30, 2003.

On November 17, 2003, St. Paul and Travelers Property Casualty Corp. ("Travelers") announced that they had signed a definitive merger agreement, under which holders of Travelers common stock will each receive common shares of St. Paul in exchange for their Travelers shares. The transaction is subject to customary closing conditions, including approval by the shareholders of both companies as well as certain regulatory approvals.

If this merger transaction were to constitute a change of control of Nuveen Advisory it would operate as an "assignment," as defined in the 1940 Act, of the Fund's investment management agreement (as discussed further below), which would cause the investment management agreement to terminate. In the event of such a termination, it is expected that the Fund's Board would meet to consider both an interim investment management agreement (as permitted under the 1940 Act) and a new investment management agreement, the latter of which, if approved by the Board, would be submitted to a vote of the Fund's shareholders and take effect only upon such approval. There is no assurance that these approvals would be obtained. The Fund and Nuveen Advisory currently expect that they will receive advice of counsel to the effect that the merger will not constitute a change of control of Nuveen Advisory and will not operate as an "assignment," and that therefore the Fund's investment management agreement would not terminate as a result of the merger. There is no assurance that the Fund will receive such advice of counsel.

As a result of the current ownership by Citigroup Inc. ("Citigroup") and its affiliates of voting securities of Travelers and St. Paul, if the transaction occurs on currently contemplated terms, Citigroup may indirectly own a sufficient percentage of voting securities of the combined entity to make Citigroup an indirect affiliate of Nuveen, Nuveen Advisory and the Fund. Such an affiliation could result, pursuant to the 1940 Act, in restrictions on transactions between the Fund and Citigroup and possibly its affiliates. In particular, principal trades between the Fund and Citigroup and its affiliates could be prohibited. Such a prohibition could have an adverse impact on the Fund's ability to efficiently invest its portfolio. Nuveen Advisory does not believe, however, that any potential inability to so trade with Citigroup or its affiliates would have a material adverse effect on Nuveen Advisory's ability to perform its obligations under the investment management agreement with the Fund or on the Fund's ability to pursue its investment objectives and policies as described in this prospectus.

23

DESCRIPTION OF MUNIPREFERRED SHARES

The following is a brief description of the terms of the MuniPreferred shares. This description does not purport to be complete and is subject to and qualified in its entirety by reference to the more detailed description of the MuniPreferred shares in the Fund's Statement attached as Appendix A to the Statement of Additional Information.

GENERAL

The Fund's Declaration of Trust authorizes the issuance of an unlimited number of preferred shares, par value $.01 per share, in one or more classes or series, with rights as determined by the Board of Trustees without the approval of holders of common shares. The Statement currently authorizes the issuance of 3,000, 1,600 and 1,600 shares of MuniPreferred Series M, Series T and Series W, respectively. All MuniPreferred shares will have a liquidation preference of $25,000 per share plus an amount equal to accumulated but unpaid dividends (whether or not earned or declared).

The MuniPreferred shares of each series will rank on parity with shares of any other series of MuniPreferred and with shares of any other series of preferred shares of the Fund as to the payment of dividends and the distribution of assets upon liquidation. All MuniPreferred shares carry one vote per share on all matters on which such shares are entitled to be voted. Shares of MuniPreferred are, when issued, fully paid and, subject to matters discussed in "Certain Provisions in the Declaration of Trust," non-assessable and have no preemptive, conversion or cumulative voting rights.

DIVIDENDS AND DIVIDEND PERIODS

General. The initial Rate Period of MuniPreferred shares Series M, Series T and Series W will be a period consisting of days, days and days, respectively. Any Subsequent Rate Period of shares of a series of MuniPreferred will be a Minimum Rate Period (7 Rate Period Days), unless the Fund, subject to certain conditions, designates such Subsequent Rate Period as a Special Rate Period. See "-- Designation of Special Rate Periods" below.

Dividends on shares of each series of MuniPreferred shall be payable, when, as and if declared by the Board out of funds legally available therefor in accordance with the Declaration of Trust, including the Statement, and applicable law. For the initial Rate Period for shares of MuniPreferred Series M, dividends will be paid on , 2004. For the initial Rate Period for shares of MuniPreferred Series T, dividends will be paid on , 2004, and on the first business day of each month thereafter, with the last dividend payment date for the initial Rate Period on , 200 . For the initial Rate Period for shares of MuniPreferred Series W, dividends will be paid on , 2004 and on the first business day of each month thereafter, with the last dividend payment date for the initial Rate Period on , 200 . After the initial Rate Period, for Subsequent Rate Periods dividends for Rate Periods other than Special Rate Periods will normally be paid on each Tuesday, Wednesday and Thursday for Series M, Series T and Series W, respectively; provided, however, that (i) if the Monday or the Tuesday on which dividends would otherwise be payable as set forth above is not a Business Day, then such dividends shall be payable on such shares on the first Business Day that falls after such Monday or Tuesday, as the case may be; (ii) if the Wednesday, Thursday or Friday on which dividends would otherwise be payable as set forth above is not a Business Day, then such dividends shall be payable on such shares on the first Business Day that falls prior to such Wednesday, Thursday or Friday, as the case may be; and (iii) the Fund may specify different Dividend Payment Dates in respect of any Special Rate Period of more than 28 Rate Period Days.

The amount of dividends per share payable on shares of a series of MuniPreferred on any date on which dividends shall be payable on shares of such series shall be computed by multiplying the Applicable Rate for shares of such series in effect for such Dividend Period or Dividend Periods or part thereof for which dividends have not been paid by a fraction, the numerator of which shall be the number of days in such Dividend Period or Dividend Periods or part thereof and the denominator of which shall be 365 if such Dividend Period consists of 7 Rate Period Days and 360 for all other Dividend Periods, and applying the rate obtained against $25,000.

25

Dividends will be paid through the Securities Depository on each Dividend Payment Date in accordance with its normal procedures, which currently provide for it to distribute dividends in next-day funds to Agent Members, who in turn are expected to distribute such dividend payments to the persons for whom they are acting as agents. Each of the current Broker-Dealers, however, has indicated to the Fund that such Broker-Dealer or the Agent Member designated by such Broker-Dealer will make such dividend payments available in same-day funds on each Dividend Payment Date to customers that use such Broker-Dealer or its designee as Agent Member.

Dividends on shares of each series of MuniPreferred will accumulate from the Date of Original Issue thereof. The dividend rate for shares of MuniPreferred of a particular series for the initial Rate Period for such shares shall be % per annum for Series M, % per annum for Series T and % per annum for Series W. For each Subsequent Rate Period of shares of MuniPreferred of a particular series, the dividend rate for such shares will be the Applicable Rate for such shares that the Auction Agent advises the Fund results from an Auction, except as provided below. The Applicable Rate that results from an Auction for shares of any series of MuniPreferred will not be greater than the Maximum Rate for shares of such series, which is:

(a) in the case of any Auction Date which is not the Auction Date immediately prior to the first day of any proposed Special Rate Period, the product of (i) the Reference Rate on such Auction Date for the next Rate Period of shares of such series and (ii) the Rate Multiple on such Auction Date, unless shares of such series have or had a Special Rate Period (other than a Special Rate Period of 28 Rate Period Days or fewer) and an Auction at which Sufficient Clearing Bids existed has not yet occurred for a Minimum Rate Period of shares of such series after such Special Rate Period, in which case the higher of:

(A) the dividend rate on shares of such series for the then-ending Rate Period; and

(B) the product of (x) the higher of (I) the Reference Rate on such Auction Date for a Rate Period equal in length to the then-ending Rate Period of shares of such series, if such then-ending Rate Period was 364 Rate Period Days or fewer, or the Treasury Note Rate on such Auction Date for a Rate Period equal in length to the then-ending Rate Period of shares of such series, if such then-ending Rate Period was more than 364 Rate Period Days, and (II) the Reference Rate on such Auction Date for a Rate Period equal in length to such Special Rate Period of shares of such series, if such Special Rate Period was 364 Rate Period Days or fewer, or the Treasury Note Rate on such Auction Date for a Rate Period equal in length to such Special Rate Period, if such Special Rate Period was more than 364 Rate Period Days and (y) the Rate Multiple on such Auction Date; or

(b) in the case of any Auction Date which is the Auction Date immediately prior to the first day of any proposed Special Rate Period, the product of (i) the highest of (x) the Reference Rate on such Auction Date for a Rate Period equal in length to the then-ending Rate Period of shares of such series, if such then-ending Rate Period was 364 Rate Period Days or fewer, or the Treasury Note Rate on such Auction Date for a Rate Period equal in length to the then-ending Rate Period of shares of such series, if such then-ending Rate Period was more than 364 Rate Period Days, (y) the Reference Rate on such Auction Date for the Special Rate Period for which the Auction is being held if such Special Rate Period is 364 Rate Period Days or fewer or the Treasury Note Rate on such Auction Date for the Special Rate Period for which the Auction is being held if such Special Rate Period is more than 364 Rate Period Days, and (z) the Reference Rate on such Auction Date for Minimum Rate Periods and (ii) the Rate Multiple on such Auction Date.

If an Auction for any Subsequent Rate Period of shares of any series of MuniPreferred is not held for any reason other than as described below, the dividend rate on shares of such series for such Subsequent Rate Period will be the Maximum Rate for shares of such series on the Auction Date for such Subsequent Rate Period.

If the Fund fails to pay in a timely manner to the Auction Agent the full amount of any dividend on, or the redemption price of, any shares of any series of MuniPreferred during any Rate Period thereof (other than any Special Rate Period of more than 364 Rate Period Days or any Rate Period succeeding any Special Rate

26

Period of more than 364 Rate Period Days during which such a failure occurred that has not been cured), but, prior to 12:00 noon on the third Business Day next succeeding the date such failure occurred, such failure shall have been cured and the Fund shall have paid a late charge, as described more fully in the Statement, no Auction will be held in respect of shares of such series for the first Subsequent Rate Period thereof thereafter and the dividend rate for shares of such series for such Subsequent Rate Period will be the Maximum Rate for shares of such series on the Auction Date for such Subsequent Rate Period.

If the Fund fails to pay in a timely manner to the Auction Agent the full amount of any dividend on, or the redemption price of, any shares of any series of MuniPreferred during any Rate Period thereof (other than any Special Rate Period of more than 364 Rate Period Days or any Rate Period succeeding any Special Rate Period of more than 364 Rate Period Days during which such a failure occurred that has not been cured), and, prior to 12:00 noon on the third Business Day next succeeding the date on which such failure occurred, such failure shall not have been cured or the Fund shall not have paid a late charge, as described more fully in the Statement, no Auction will be held in respect of shares of such series for the first Subsequent Rate Period thereof thereafter (or for any Rate Period thereof thereafter to and including the Rate Period during which such failure is so cured and such late charge so paid) (such late charge to be paid only in the event Moody's is rating such shares at the time the Fund cures such failure), and the dividend rate for shares of such series for each such Subsequent Rate Period shall be a rate per annum equal to the Maximum Rate for shares of such series on the Auction Date for such Subsequent Rate Period (but with the prevailing rating for shares of such series, for purposes of determining such Maximum Rate, being deemed to be "Below 'ba3'/'BB2"').

If the Fund fails to pay in a timely manner to the Auction Agent the full amount of any dividend on, or the redemption price of, any shares of any series of MuniPreferred during a Special Rate Period thereof of more than 364 Rate Period Days, or during any Rate Period thereof succeeding any Special Rate Period of more than 364 Rate Period Days during which such a failure occurred that has not been cured, and such failure shall not have been cured or the Fund shall not have paid a late charge, as described more fully in the Statement, no Auction will be held in respect of shares of such series for such Subsequent Rate Period thereof (or for any Rate Period thereof thereafter to and including the Rate Period during which such failure is so cured and such late charge so paid) (such late charge to be paid only in the event Moody's is rating such shares at the time the Fund cures such failure), and the dividend rate for shares of such series for each such Subsequent Rate Period shall be a rate per annum equal to the Maximum Rate for shares of such series on the Auction Date for each such Subsequent Rate Period (but with the prevailing rating for shares of such series, for purposes of determining such Maximum Rate, being deemed to be "Below 'ba3'/'BB2"').

A failure to pay dividends on, or the redemption price of, shares of any series of MuniPreferred shall have been cured with respect to any Rate Period thereof if, within the respective time periods described in the Statement, the Fund shall have paid to the Auction Agent (a) all accumulated and unpaid dividends on the shares of such series and (b) without duplication, the redemption price for shares, if any, of such series for which notice of redemption has been mailed by the Fund; provided, however, that the foregoing clause (b) shall not apply to the Fund's failure to pay the redemption price in respect of shares of MuniPreferred when the related notice of redemption provides that redemption of such shares is subject to one or more conditions precedent and any such condition precedent shall not have been satisfied at the time or times and in the manner specified in such notice of redemption.

Gross-up Payments. Holders of shares of MuniPreferred are entitled to receive, when, as and if declared by the Board, out of funds legally available therefor in accordance with the Declaration of Trust, including the Statement, and applicable law, dividends in an amount equal to the aggregate Gross-up Payments in accordance with the following:

If, in the case of any Minimum Rate Period or any Special Rate Period of 28 Rate Period Days or fewer, the Fund allocates any net capital gain or other income taxable for regular federal income tax purposes to a dividend paid on shares of MuniPreferred without having given advance notice thereof to the Auction Agent as described below under "The Auction -- Auction Procedures" (a "Taxable Allocation") solely by reason of the fact that such allocation is made retroactively as a result of the redemption of all or a portion of the outstanding shares of MuniPreferred or the liquidation of the Fund, the Fund will, prior to the end of the

27

calendar year in which such dividend was paid, provide notice thereof to the Auction Agent and direct the Fund's dividend disbursing agent to send such notice with a Gross-up Payment to each holder of shares (initially Cede & Co., as nominee of the Securities Depository) that was entitled to such dividend payment during such calendar year at such holder's address as the same appears or last appeared on the stock books of the Fund.

If, in the case of any Special Rate Period or initial Rate Period of more than 28 Rate Period Days (including the Extended Initial Rate Period with respect to each of Series T and Series W), the Fund makes a Taxable Allocation to a dividend paid on shares of MuniPreferred without having given prior to the auction with respect to that Rate Period to the Auction Agent advance notice thereof, the Fund shall, prior to the end of the calendar year in which such dividend was paid, provide notice thereof to the Auction Agent and direct the Fund's dividend disbursing agent to send such notice with a Gross-up Payment to each holder of shares that was entitled to such dividend payment during such calendar year at such holder's address as the same appears or last appeared on the stock books of the Fund.

A "Gross-up Payment" means payment to a holder of shares of MuniPreferred of an amount which, when taken together with the aggregate amount of Taxable Allocations made to such holder to which such Gross-up Payment relates, would cause such holder's dividends in dollars (after federal income tax consequences) from the aggregate of such Taxable Allocations and the related Gross-up Payment to be equal to the dollar amount of the dividends which would have been received by such holder if the amount of the aggregate Taxable Allocations would have been excludable from the gross income of such holder. Such Gross-up Payment shall be calculated: (a) without consideration being given to the time value of money; (b) assuming that no holder of shares of MuniPreferred is subject to the federal alternative minimum tax with respect to dividends received from the Fund; and (c) assuming that each Taxable Allocation and each Gross-up Payment (except to the extent such Gross-up Payment is designated as an exempt-interest dividend under Section 852(b)(5) of the Internal Revenue Code of 1986, as amended, or successor provisions) would be taxable in the hands of each holder of shares of MuniPreferred at the maximum marginal regular federal individual income tax rate applicable to ordinary income or net capital gain, as applicable, or the maximum marginal regular federal corporate income tax rate applicable to ordinary income or net capital gain, as applicable, whichever is greater, in effect at the time such Gross-up Payment is made.

Restrictions on Dividends and Other Distributions. Except as otherwise described herein, for so long as any shares of MuniPreferred are outstanding, the Fund may not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in, or in options, warrants or rights to subscribe for or purchase, its shares of common shares) in respect of its common shares or any other shares of the Fund ranking junior to, or on parity with, shares of MuniPreferred as to the payments of dividends or the distribution of assets upon dissolution, liquidation or winding up, or call for redemption, redeem, purchase or otherwise acquire for consideration any common shares or other such junior shares or other such parity shares (except by conversion into or exchange for shares of the Fund ranking junior to the shares of MuniPreferred as to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the affairs of the Fund), unless
(a) full cumulative dividends on shares of each series of MuniPreferred through its most recently ended Dividend Period shall have been paid or shall have been declared and sufficient funds for the payment thereof deposited with the Auction Agent and (b) the Fund shall have redeemed the full number of shares of MuniPreferred required to be redeemed by any provision for mandatory redemption pertaining thereto. Except as otherwise described herein, for so long as any shares of MuniPreferred are outstanding, the Fund may not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or in options, warrants or rights to subscribe for or purchase, common shares or other shares, if any, ranking junior to shares of MuniPreferred as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up) in respect of common shares or any other shares of the Fund ranking junior to shares of MuniPreferred as to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up, or call for redemption, redeem, purchase or otherwise acquire for consideration any common shares or any other such junior shares (except by conversion into or exchange for shares of the Fund ranking junior to shares of MuniPreferred as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up), unless

28

immediately after such transaction the Discounted Value of the Fund's portfolio would at least equal the MuniPreferred Basic Maintenance Amount in accordance with guidelines of the rating agency or agencies then rating the shares of MuniPreferred.

Except as set forth in the next sentence, no dividends shall be declared or paid or set apart for payment on the shares of any class or series of Fund shares ranking, as to the payment of dividends, on a parity with shares of MuniPreferred for any period unless full cumulative dividends have been or contemporaneously are declared and paid on the shares of each series of MuniPreferred through its most recent Dividend Payment Date. When dividends are not paid in full upon the shares of each series of MuniPreferred through its most recent Dividend Payment Date or upon the shares of any other class or series of shares ranking on a parity as to the payment of dividends with shares of MuniPreferred through their most recent respective dividend payment dates, all dividends declared upon shares of MuniPreferred and any such other class or series of shares ranking on a parity as to the payment of dividends with shares of MuniPreferred shall be declared pro rata so that the amount of dividends declared per share on shares of MuniPreferred and such other class or series of shares shall in all cases bear to each other the same ratio that accumulated dividends per share on the shares of MuniPreferred and such other class or series of shares bear to each other.

Designation of Special Rate Periods. The Fund, at its option, may designate any succeeding Subsequent Rate Period of shares of a particular series of MuniPreferred as a Special Rate Period consisting of a specified number of Rate Period Days evenly divisible by seven and not more than 1,820 (approximately 5 years), subject to certain adjustments. A designation of a Special Rate Period shall be effective only if, among other things, (a) the Fund shall have given certain notices to the Auction Agent, (b) an Auction for shares of such series shall have been held on the Auction Date immediately preceding the first day of such proposed Special Rate Period and Sufficient Clearing Bids for shares of such series shall have existed in such Auction and (c) if the Fund shall have mailed a notice of redemption with respect to any shares of such series, the redemption price with respect to such shares shall have been deposited with the Auction Agent. The Fund will give MuniPreferred shareholders notice of a special rate period as provided in the Statement.

REDEMPTION

Mandatory Redemption. In the event the Fund does not timely cure a failure to maintain (a) a Discounted Value of its eligible portfolio securities equal to the MuniPreferred Basic Maintenance Amount or (b) the 1940 Act MuniPreferred Asset Coverage (as defined below), in each case in accordance with the requirements of the rating agency or agencies then rating the shares of MuniPreferred, shares of MuniPreferred will be subject to mandatory redemption on a date specified by the Board out of funds legally available therefor in accordance with the Declaration of Trust, including the Statement, and applicable law, at the redemption price of $25,000 per share plus an amount equal to accumulated but unpaid dividends thereon (whether or not earned or declared) to (but not including) the date fixed for redemption. Any such redemption will be limited to the lesser of the number of shares of MuniPreferred necessary to restore the required Discounted Value or the 1940 Act MuniPreferred Asset Coverage, as the case may be, or the maximum number that can be redeemed with the funds legally available under the Declaration of Trust and applicable law.

Optional Redemption. Shares of MuniPreferred of each series are redeemable, at the option of the Fund:

(a) as a whole or from time to time in part, on the second Business Day preceding any Dividend Payment Date for shares of such series, out of funds legally available therefor in accordance with the Declaration of Trust, including the Statement, and applicable law, at the redemption price of $25,000 per share plus an amount equal to accumulated but unpaid dividends thereon (whether or not earned or declared) to (but not including) the date fixed for redemption; provided, however, that (i) shares of such series may not be redeemed in part if after such partial redemption fewer than 250 shares of such series would remain outstanding;
(ii) shares of a series of MuniPreferred are redeemable by the Fund during the Initial Rate Period thereof only on the second Business Day next preceding the last Dividend Payment Date for such Initial Rate Period; and
(iii) the notice establishing a Special Rate Period of

29

shares of such series, as delivered to the Auction Agent and filed with the Secretary of the Fund, may provide that shares of such series shall not be redeemable during the whole or any part of such Special Rate Period (except as provided in clause (b) below) or shall be redeemable during the whole or any part of such Special Rate Period only upon payment of such redemption premium or premiums as shall be specified therein; and

(b) as a whole but not in part, out of funds legally available therefor in accordance with the Declaration of Trust, including the Statement, and applicable law, on the first day following any Dividend Period thereof included in a Rate Period of more than 364 Rate Period Days if, on the date of determination of the Applicable Rate for shares of such series for such Rate Period, such Applicable Rate equaled or exceeded on such date of determination the Treasury Note Rate for such Rate Period, at a redemption price of $25,000 per share plus an amount equal to accumulated but unpaid dividends thereon (whether or not earned or declared) to (but not including) the date fixed for redemption.

Notwithstanding the foregoing, if any dividends on shares of a series of MuniPreferred (whether or not earned or declared) are in arrears, no shares of such series shall be redeemed unless all outstanding shares of such series are simultaneously redeemed, and the Fund shall not purchase or otherwise acquire any shares of such series; provided, however, that the foregoing shall not prevent the purchase or acquisition of all outstanding shares of such series pursuant to the successful completion of an otherwise lawful purchase or exchange offer made on the same terms to, and accepted by, holders of all outstanding shares of such series.

LIQUIDATION

Subject to the rights of holders of any series or class or classes of shares ranking on a parity with shares of MuniPreferred with respect to the distribution of assets upon liquidation of the Fund, upon a liquidation of the Fund, whether voluntary or involuntary, the holders of shares of MuniPreferred then outstanding will be entitled to receive and to be paid out of the assets of the Fund available for distribution to its shareholders, before any payment or distribution shall be made on the common shares, an amount equal to the liquidation preference with respect to such shares ($25,000 per share), plus an amount equal to all dividends thereon (whether or not earned or declared) accumulated but unpaid to (but not including) the date of final distribution in same-day funds, together with any applicable Gross-up Payments in connection with the liquidation of the Fund. After the payment to the holders of shares of MuniPreferred of the full preferential amounts provided for as described herein, the holders of shares of MuniPreferred as such shall have no right or claim to any of the remaining assets of the Fund.

Neither the sale of all or substantially all the property or business of the Fund, nor the merger or consolidation of the Fund into or with any Massachusetts business trust or corporation nor the merger or consolidation of any Massachusetts business trust or corporation into or with the Fund, shall be a liquidation, whether voluntary or involuntary, for the purposes of the foregoing paragraph.

RATING AGENCY GUIDELINES AND ASSET COVERAGE

The Fund is required under Moody's and S&P guidelines ("the Rating Agency Guidelines") to maintain assets having in the aggregate a Discounted Value at least equal to the MuniPreferred Basic Maintenance Amount. Moody's and S&P have each established separate Rating Agency Guidelines for determining Discounted Value. To the extent any particular portfolio holding does not satisfy the applicable Rating Agency's Guidelines, all or a portion of such holding's value will not be included in the calculation of Discounted Value (as defined by such rating agency). Although the Rating Agency Guidelines impose certain restrictions on the Fund's investments, Rating Agency Guidelines do not impose any limitations on the percentage of the Fund's assets that may be invested in holdings not otherwise restricted by the Rating Agency Guidelines and that are eligible for inclusion in the calculation of the Discounted Value of the Fund's portfolio. The amount of such assets included in the portfolio at any time may vary depending upon the rating, diversification and other characteristics of the eligible assets included in the portfolio, although it is not anticipated that in the normal course of business the value of such assets would exceed 20% of the Fund's total assets. The MuniPreferred Basic Maintenance Amount includes the sum of (a) the aggregate liquidation

30

preference of shares of MuniPreferred then outstanding and (b) certain accrued and projected payment obligations of the Fund.

The Rating Agency Guidelines, as each may be amended from time to time by the respective rating agency, will be reflected in a written document. A copy of the current Rating Agency Guidelines will be provided to any holder of MuniPreferred promptly upon written request therefor made by such holder to the Fund at: 333 W. Wacker Dr., Chicago, IL 60606.

The Fund is also required under the 1940 Act and rating agency guidelines to maintain, with respect to shares of MuniPreferred, as of the last Business Day of each month in which any such shares are outstanding, asset coverage of at least 200% with respect to all outstanding senior securities which are shares of beneficial interest, including MuniPreferred (or such other asset coverage as may in the future be specified in or under the 1940 Act as the minimum asset coverage for senior securities which are shares of a closed-end investment company as a condition of declaring dividends on its common shares) ("1940 Act MuniPreferred Asset Coverage"). Based on the composition of the portfolio of the Fund and market conditions as of January 8, 2004, 1940 Act MuniPreferred Asset Coverage with respect to shares of MuniPreferred, assuming the issuance on the date thereof of all shares of MuniPreferred offered hereby and giving effect to the deduction of sales load and offering costs related thereto estimated at $3,355,000, would have been computed as follows:

         Value of Fund assets less liabilities not
               constituting senior securities                       $490,181,433
------------------------------------------------------------   =    ---------------    =    316%
      Senior securities representing indebtedness plus              $155,000,000
      liquidation value of the shares of MuniPreferred

In the event the Fund does not timely cure a failure to maintain (a) a Discounted Value of its portfolio equal to the MuniPreferred Basic Maintenance Amount or (b) the 1940 Act MuniPreferred Asset Coverage, in each case in accordance with the requirements of the rating agency or agencies then rating the shares of MuniPreferred, the Fund will be required to redeem shares of MuniPreferred as described under "Redemption -- Mandatory Redemption" above.

Moody's or S&P (or any other rating agency providing a rating for the MuniPreferred) may change from time to time its Rating Agency Guidelines without Fund, Board of Trustees or shareholder approval. In addition, any rating agency providing a rating for the shares of MuniPreferred may, at any time, change or withdraw any such rating. The Board may, without shareholder approval, adopt, amend, alter or repeal any or all of the definitions set forth in the Statement or add covenants and other obligations of the Fund or confirm the applicability of covenants and other obligations set forth in the Statement in connection with obtaining or maintaining the rating of any rating agency which is then rating shares of MuniPreferred and any such adoption, amendment, alteration or repeal will not be deemed to affect the preferences, rights or powers of MuniPreferred or holders of MuniPreferred, provided the Board of Trustees receives written confirmation from Moody's or S&P, or both, as appropriate, that any such amendment, alteration or repeal would not adversely affect the ratings then assigned by Moody's and S&P to shares of MuniPreferred.

As recently described by Moody's and S&P, a preferred stock rating is an assessment of the capacity and willingness of an issuer to pay preferred stock obligations. The ratings on the shares of MuniPreferred are not recommendations to purchase, hold or sell those shares, inasmuch as the ratings do not comment as to market price or suitability for a particular investor. The rating agency guidelines described above also do not address the likelihood that an owner of shares of MuniPreferred will be able to sell such shares in an Auction or otherwise. The ratings are based on current information furnished to Moody's and S&P by the Fund and the Adviser and information obtained from other sources. The ratings may be changed, suspended or withdrawn as a result of changes in, or the unavailability of, such information. The common shares have not been rated by a nationally recognized statistical rating organization.

A rating agency's guidelines will apply to shares of MuniPreferred only so long as such rating agency is rating such shares. The Fund will pay certain fees to Moody's or S&P, or both, for rating shares of MuniPreferred.

31

VOTING RIGHTS

Except as otherwise provided in this prospectus and in the Statement of Additional Information, in the Declaration of Trust or as otherwise required by law, holders of shares of MuniPreferred will have equal voting rights with holders of common shares and any Preferred Shares (one vote per share) and will vote together with holders of common shares and any Preferred Shares as a single class.

In connection with the election of the Fund's trustees, holders of outstanding Preferred Shares, including MuniPreferred shares, voting as a separate class, are entitled to elect two of the Fund's trustees, and the remaining trustees are elected by holders of common shares and Preferred Shares, including MuniPreferred shares, voting together as a single class. In addition, if at any time dividends (whether or not earned or declared) on outstanding Preferred Shares, including MuniPreferred shares, shall be due and unpaid in an amount equal to two full years' dividends thereon, and sufficient cash or specified securities shall not have been deposited with the Auction Agent for the payment of such dividends, then, as the sole remedy of holders of outstanding Preferred Shares, including MuniPreferred shares, the number of trustees constituting the Board shall be automatically increased by the smallest number that, when added to the two trustees elected exclusively by the holders of Preferred Shares, including shares of MuniPreferred, as described above, would constitute a majority of the Board as so increased by such smallest number, and at a special meeting of shareholders which will be called and held as soon as practicable, and at all subsequent meetings at which trustees are to be elected, the holders of Preferred Shares, including shares of MuniPreferred, voting as a separate class, will be entitled to elect the smallest number of additional trustees that, together with the two trustees which such holders will be in any event entitled to elect, constitutes a majority of the total number of trustees of the Fund as so increased. The terms of office of the persons who are trustees at the time of that election will continue. If the Fund thereafter shall pay, or declare and set apart for payment, in full, all dividends payable on all outstanding Preferred Shares, including MuniPreferred shares, the voting rights stated in the second preceding sentence shall cease, and the terms of office of all of the additional trustees elected by the holders of Preferred Shares, including MuniPreferred shares (but not of the trustees with respect to whose election the holders of common shares were entitled to vote or the two trustees the holders of Preferred Shares have the right to elect in any event), will terminate automatically.

So long as any shares of MuniPreferred are outstanding, the Fund will not, without the affirmative vote or consent of the holders of at least a majority of the shares of MuniPreferred outstanding at the time (voting as a separate class):

(a) authorize, create or issue any class or series of stock ranking prior to or on a parity with shares of MuniPreferred with respect to the payment of dividends or the distribution of assets upon liquidation, dissolution or winding up of the affairs of the Fund or authorize, create or issue additional shares of any series of MuniPreferred (except that, notwithstanding the foregoing, but subject to certain rating agency approvals, the Board, without the vote or consent of the holders of MuniPreferred, may from time to time authorize and create, and the Fund may from time to time issue additional shares of, any series of MuniPreferred or classes or series of Preferred Shares ranking on a parity with shares of MuniPreferred with respect to the payment of dividends and the distribution of assets upon liquidation, dissolution or winding up of the affairs of the Fund; provided, however, that if Moody's or S&P is not then rating the shares of MuniPreferred, the aggregate liquidation preference of all Preferred Shares of the Fund outstanding after any such issuance, exclusive of accumulated and unpaid dividends, may not exceed $ ) or

(b) amend, alter or repeal the provisions of the Declaration of Trust, including the Statement, whether by merger, consolidation or otherwise, so as to affect any preference, right or power of such shares of MuniPreferred or the holders thereof;

provided, however, that (i) none of the actions permitted by the exception to
(a) above will be deemed to affect such preferences, rights or powers, (ii) a division of a share of MuniPreferred will be deemed to affect such preferences, rights or powers only if the terms of such division adversely affect the holders of shares of MuniPreferred and (iii) the authorization, creation and issuance of classes or series of stock ranking junior to shares of MuniPreferred with respect to the payment of dividends and the distribution of assets upon

32

liquidation, dissolution or winding up of the affairs of the Fund will be deemed to affect such preferences, rights or powers only if Moody's or S&P is then rating shares of MuniPreferred and such issuance would, at the time thereof, cause the Fund not to satisfy the 1940 Act MuniPreferred Asset Coverage or the MuniPreferred Basic Maintenance Amount. So long as any shares of MuniPreferred are outstanding, the Fund shall not, without the affirmative vote or consent of the holders of at least 66 2/3% of the shares of MuniPreferred outstanding at the time, voting as a separate class, file a voluntary application for relief under federal bankruptcy law or any similar application under state law for so long as the Fund is solvent and does not foresee becoming insolvent.

If any action set forth above would adversely affect the rights of one or more series (the "Affected Series") of MuniPreferred shares in a manner different from any other series of MuniPreferred shares, the Fund will not approve any such action without the affirmative vote or consent of the holders of at least a majority of the shares of each such Affected Series outstanding at the time, in person or by proxy, either in writing or at a meeting (each such Affected Series voting as a separate class). The Board may, without shareholder approval, amend, alter or repeal any or all of the definitions and related provisions which have been adopted by the Fund pursuant to the rating agency guidelines in the event the Fund receives written confirmation from Moody's or S&P, or both, as appropriate, that any such amendment, alteration or repeal would not impair the ratings then assigned by Moody's and S&P to shares of MuniPreferred. Unless a higher percentage is provided for in the Declaration of Trust (see "Certain Provisions in the Declaration of Trust"), (A) the affirmative vote of the holders of at least a majority of the Preferred Shares, including MuniPreferred shares, outstanding at the time, voting as a separate class, shall be required to approve any conversion of the Fund from a closed-end to an open-end investment company and (B) the affirmative vote of the holders of a majority of the outstanding Preferred Shares, including MuniPreferred shares, voting as a separate class, shall be required to approve any plan of reorganization (as such term is used in the 1940 Act) adversely affecting such shares. The affirmative vote of the holders of a majority of the outstanding Preferred Shares, including MuniPreferred shares, voting as a separate class, shall be required to approve any action not described in the preceding sentence requiring a vote of security holders of the Fund under Section 13(a) of the 1940 Act.

The foregoing voting provisions will not apply with respect to shares of MuniPreferred if, at or prior to the time when a vote is required, such shares shall have been (i) redeemed or (ii) called for redemption and sufficient funds shall have been deposited in trust to effect such redemption.

THE AUCTION

GENERAL

The Statement provides that, except as otherwise described herein, the Applicable Rate for the shares of each series of MuniPreferred, including the shares of MuniPreferred to be issued in this offering, for each Rate Period of shares of such series after the initial Rate Period thereof shall be equal to the rate per annum that the Auction Agent advises has resulted on the Business Day preceding the first day of such Subsequent Rate Period (an "Auction Date") from implementation of the auction procedures (the "Auction Procedures") set forth in the Statement and summarized below, in which persons determine to hold or offer to sell or, based on dividend rates bid by them, offer to purchase or sell shares of such series. Each periodic implementation of the Auction Procedures is referred to herein as an "Auction." See the Statement for a more complete description of the Auction process.

Auction Agency Agreement. The Fund has entered into an Auction Agency Agreement (the "Auction Agency Agreement") with the Auction Agent (currently, Deutsche Bank Trust Company Americas) which provides, among other things, that the Auction Agent will follow the Auction Procedures for purposes of determining the Applicable Rate for shares of each series of MuniPreferred so long as the Applicable Rate for shares of such series is to be based on the results of an Auction.

The Auction Agent may terminate the Auction Agency Agreement upon notice to the Fund on a date no earlier than 45 days after such notice. If the Auction Agent should resign, the Fund will use its best efforts to enter into an agreement with a successor Auction Agent containing substantially the same terms and

33

conditions as the Auction Agency Agreement. The Fund may remove the Auction Agent provided that prior to such removal the Fund shall have entered into such an agreement with a successor Auction Agent.

Broker-Dealer Agreements. Each Auction requires the participation of one or more Broker-Dealers. The Auction Agent has entered into agreements (collectively, the "Broker-Dealer Agreements") with several Broker-Dealers selected by the Fund, which provide for the participation of those Broker-Dealers in Auctions for shares of MuniPreferred.

The Auction Agent after each Auction for shares of MuniPreferred will pay to each Broker-Dealer, from funds provided by the Fund, a service charge at the annual rate of 1/4 of 1% in the case of any Auction immediately preceding a Rate Period of less than one year, or a percentage agreed to by the Fund and the Broker-Dealers in the case of any Auction immediately preceding a Rate Period of one year or longer, of the purchase price of shares of MuniPreferred placed by such Broker-Dealer at such Auction. For the purposes of the preceding sentence, shares of MuniPreferred will be placed by a Broker-Dealer if such shares were
(a) the subject of Hold Orders deemed to have been submitted to the Auction Agent by the Broker-Dealer and were acquired by such Broker-Dealer for its own account or were acquired by such Broker-Dealer for its customers who are Beneficial Owners or (b) the subject of an Order submitted by such Broker-Dealer that is (i) a Submitted Bid of an Existing Holder that resulted in such Existing Holder continuing to hold such shares as a result of the Auction or (ii) a Submitted Bid of a Potential Holder that resulted in such Potential Holder purchasing such shares as a result of the Auction or (iii) a valid Hold Order.

The Fund may request the Auction Agent to terminate one or more Broker-Dealer Agreements at any time, provided that at least one Broker-Dealer Agreement is in effect after such termination.

AUCTION PROCEDURES

Prior to the Submission Deadline on each Auction Date for shares of a series of MuniPreferred, each customer of a Broker-Dealer who is listed on the records of that Broker-Dealer (or, if applicable, the Auction Agent) as a holder of shares of such series (a "Beneficial Owner") may submit orders ("Orders") with respect to shares of such series to that Broker-Dealer as follows:

- Hold Order -- indicating its desire to hold shares of such series without regard to the Applicable Rate for shares of such series for the next Rate Period thereof.

- Bid -- indicating its desire to sell shares of such series at $25,000 per share if the Applicable Rate for shares of such series for the next Rate Period thereof is less than the rate specified in such Bid (also known as a hold-at-a-rate order).

- Sell Order -- indicating its desire to sell shares of such series at $25,000 per share without regard to the Applicable Rate for shares of such series for the next Rate Period thereof.

A Beneficial Owner may submit different types of Orders to its Broker-Dealer with respect to shares of a series of MuniPreferred then held by such Beneficial Owner. A Beneficial Owner of shares of such series that submits a Bid with respect to shares of such series to its Broker-Dealer having a rate higher than the Maximum Rate for shares of such series on the Auction Date therefor will be treated as having submitted a Sell Order with respect to such shares to its Broker-Dealer. A Beneficial Owner of shares of such series that fails to submit an Order with respect to such shares to its Broker-Dealer will be deemed to have submitted a Hold Order with respect to such shares of such series to its Broker-Dealer; provided, however, that if a Beneficial Owner of shares of such series fails to submit an Order with respect to shares of such series to its Broker-Dealer for an Auction relating to a Rate Period of more than 28 Rate Period Days, such Beneficial Owner will be deemed to have submitted a Sell Order with respect to such shares to its Broker-Dealer. A Sell Order shall constitute an irrevocable offer to sell the shares of MuniPreferred subject thereto. A Beneficial Owner that offers to become the Beneficial Owner of additional shares of MuniPreferred is, for purposes of such offer, a Potential Beneficial Owner as discussed below.

A customer of a Broker-Dealer that is not a Beneficial Owner of shares of a series of MuniPreferred but that wishes to purchase shares of such series, or that is a Beneficial Owner of shares of such series that wishes

34

to purchase additional shares of such series (in each case, a "Potential Beneficial Owner"), may submit Bids to its Broker-Dealer in which it offers to purchase shares of such series at $25,000 per share if the Applicable Rate for shares of such series for the next Rate Period thereof is not less than the rate specified in such Bid. A Bid placed by a Potential Beneficial Owner of shares of such series specifying a rate higher than the Maximum Rate for shares of such series on the Auction Date therefor will not be accepted.

The Broker-Dealers in turn will submit the Orders of their respective customers who are Beneficial Owners and Potential Beneficial Owners to the Auction Agent, designating themselves (unless otherwise permitted by the Fund) as Existing Holders in respect of shares subject to Orders submitted or deemed submitted to them by Beneficial Owners and as Potential Holders in respect of shares subject to Orders submitted to them by Potential Beneficial Owners. However, neither the Fund nor the Auction Agent will be responsible for a Broker-Dealer's failure to comply with the foregoing. Any Order placed with the Auction Agent by a Broker-Dealer as or on behalf of an Existing Holder or a Potential Holder will be treated in the same manner as an Order placed with a Broker-Dealer by a Beneficial Owner or Potential Beneficial Owner. Similarly, any failure by a Broker-Dealer to submit to the Auction Agent an Order in respect of any shares of MuniPreferred held by it or customers who are Beneficial Owners will be treated in the same manner as a Beneficial Owner's failure to submit to its Broker-Dealer an Order in respect of shares of MuniPreferred held by it. A Broker-Dealer may also submit Orders to the Auction Agent for its own account as an Existing Holder or Potential Holder, provided it is not an affiliate of the Fund.

If Sufficient Clearing Bids for shares of a series of MuniPreferred exist (that is, the number of shares of such series subject to Bids submitted or deemed submitted to the Auction Agent by Broker-Dealers as or on behalf of Potential Holders with rates equal to or lower than the Maximum Rate for shares of such series is at least equal to the number of shares of such series subject to Sell Orders submitted or deemed submitted to the Auction Agent by Broker-Dealers as or on behalf of Existing Holders), the Applicable Rate for shares of such series for the next succeeding Rate Period thereof will be the lowest rate specified in the Submitted Bids which, taking into account such rate and all lower rates bid by Broker-Dealers as or on behalf of Existing Holders and Potential Holders, would result in Existing Holders and Potential Holders owning the shares of such series available for purchase in the Auction. If Sufficient Clearing Bids for shares of a series of MuniPreferred do not exist, the Applicable Rate for shares of such series for the next succeeding Rate Period thereof will be the Maximum Rate for shares of such series on the Auction Date therefor. In such event, Beneficial Owners of shares of such series that have submitted or are deemed to have submitted Sell Orders may not be able to sell in such Auction all shares of such series subject to such Sell Orders. If Broker-Dealers submit or are deemed to have submitted to the Auction Agent Hold Orders with respect to all Existing Holders of shares of a series of MuniPreferred, the Applicable Rate for shares of such series for the next succeeding Rate Period thereof will be the All Hold Order Rate.

The Auction Procedures include a pro rata allocation of shares for purchase and sale, which may result in an Existing Holder continuing to hold or selling, or a Potential Holder purchasing, a number of shares of a series of MuniPreferred that is fewer than the number of shares of such series specified in its Order. To the extent the allocation procedures have that result, Broker-Dealers that have designated themselves as Existing Holders or Potential Holders in respect of customer Orders will be required to make appropriate pro rata allocations among their respective customers.

Settlement of purchases and sales will be made on the next Business Day (also a Dividend Payment Date) after the Auction Date through the Securities Depository. Purchasers will make payment through their Agent Members in same-day funds to the Securities Depository against delivery to their respective Agent Members. The Securities Depository will make payment to the sellers' Agent Members in accordance with the Securities Depository's normal procedures, which now provide for payment against delivery by their Agent Members in same-day funds.

The Auctions for shares of MuniPreferred Series M will normally be held every Monday and each Subsequent Rate Period of shares of such series will normally begin on the following Tuesday, assuming they are not Special Rate Periods. The Auctions for shares of MuniPreferred Series T following the Extended Initial Rate Period will normally be held every Tuesday and each Subsequent Rate Period of shares of such

35

series will normally begin on the following Wednesday, assuming they are not Special Rate Periods. The Auctions for shares of MuniPreferred Series W following the Initial Extended Rate Period will normally be held every Wednesday and each Subsequent Rate Period of shares of such series will normally begin on the following Thursday, assuming they are not Special Rate Periods.

Whenever the Fund intends to include any net capital gain or other income taxable for regular federal income tax purposes in any dividend on shares of MuniPreferred, the Fund shall, in the case of Minimum Rate Periods or Special Rate Periods of 28 Rate Period Days or fewer, and may, in the case of any other Special Rate Period, notify the Auction Agent of the amount to be so included not later than the Dividend Payment Date next preceding the Auction Date on which the Applicable Rate for such dividend is to be established. Whenever the Auction Agent receives such notice from the Fund, it will be required in turn to notify each Broker-Dealer, who, on or prior to such Auction Date, in accordance with its Broker-Dealer Agreement, will be required to notify its customers who are Beneficial Owners and Potential Beneficial Owners believed by it to be interested in submitting an Order in the Auction to be held on such Auction Date.

SECONDARY MARKET TRADING AND TRANSFER OF MUNIPREFERRED SHARES

The Broker-Dealers are expected to maintain a secondary trading market in shares of MuniPreferred outside of Auctions, but are not obligated to do so, and may discontinue such activity at any time. There can be no assurance that such secondary trading market in shares of MuniPreferred will provide owners with liquidity of investment. The shares of MuniPreferred are not registered on any stock exchange or on the Nasdaq Stock Market. Investors who purchase shares with an Extended Initial Rate Period or in an Auction for a Special Rate Period should note that because the dividend rate on such shares will be fixed for the length of such Rate Period, the value of the shares may fluctuate in response to changes in interest rates, and may be more or less than their original cost if sold on the open market in advance of the next Auction therefor, depending upon market conditions.

A Beneficial Owner or an Existing Holder may sell, transfer or otherwise dispose of shares of MuniPreferred only in whole shares and only (1) pursuant to a Bid or Sell Order placed with the Auction Agent in accordance with the Auction Procedures, (2) to a Broker-Dealer or (3) to such other persons as may be permitted by the Fund; provided, however, that (a) 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 as the holder of such shares to that Broker-Dealer or another customer 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 so sold, transferred or disposed of immediately after such sale, transfer or disposition and (b) in the case of all transfers other than pursuant to Auctions, the Broker-Dealer (or other person, if permitted by the Fund) to whom such transfer is made shall advise the Auction Agent of such transfer.

DESCRIPTION OF COMMON SHARES

In addition to the MuniPreferred shares, the Declaration authorizes the issuance of an unlimited number of common shares, par value of $0.01 per share. All outstanding common shares have equal rights to the payment of dividends and the distribution of assets upon liquidation, are fully paid and, subject to matters discussed in "Certain Provisions in the Declaration of Trust," non-assessable, and have no pre-emptive or conversion rights or rights to cumulative voting. Whenever MuniPreferred shares are outstanding, holders of the Fund's common shares will not be entitled to receive any cash distributions from the Fund unless all accrued dividends on MuniPreferred shares have been paid, and unless asset coverage (as defined in the 1940 Act) with respect to MuniPreferred shares would be at least 200% after giving effect to the distributions.

CERTAIN PROVISIONS IN THE DECLARATION OF TRUST

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Fund. However, the Declaration contains an express disclaimer of shareholder liability for debts or obligations of the Fund and requires that notice of such limited liability be given in each agreement, obligation or instrument entered into or executed by the Fund or the trustees. The Declaration

36

further provides for indemnification out of the assets and property of the Fund for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Fund would be unable to meet its obligations. The Fund believes that the likelihood of such circumstances is remote.

The Declaration includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. Specifically, the Declaration requires a vote by holders of at least two-thirds of the common shares and MuniPreferred shares, voting together as a single class, except as described below, to authorize (1) a conversion of the Fund from a closed-end to an open-end investment company, (2) a merger or consolidation of the Fund, or a series or class of the Fund, with any corporation, association, trust or other organization or a reorganization of the Fund, or a series or class of the Fund, (3) a sale, lease or transfer of all or substantially all of the Fund's assets (other than in the regular course of the Fund's investment activities), (4) in certain circumstances, a termination of the Fund, or a series or class of the Fund, or (5) a removal of trustees by shareholders, and then only for cause, unless, with respect to (1) through (4), such transaction has already been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-laws, in which case the affirmative vote of the holders of at least a majority of the Fund's common shares and MuniPreferred shares outstanding at the time, voting together as a single class, is required; provided, however, that where only a particular class or series is affected (or, in the case of removing a trustee, when the trustee has been elected by only one class), only the required vote by the applicable class or series will be required. Approval of shareholders is not required, however, for any transaction, whether deemed a merger, consolidation, reorganization or otherwise whereby the Fund issues shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity. In the case of the conversion of the Fund to an open-end investment company, or in the case of any of the foregoing transactions constituting a plan of reorganization which adversely affects the holders of MuniPreferred shares, the action in question will also require the affirmative vote of the holders of at least two-thirds of the Fund's MuniPreferred shares outstanding at the time, voting as a separate class, or, if such action has been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-laws, the affirmative vote of the holders of at least a majority of the Fund's MuniPreferred shares outstanding at the time, voting as a separate class. None of the foregoing provisions may be amended except by the vote of at least two-thirds of the common shares and MuniPreferred shares, voting together as a single class. The votes required to approve the conversion of the Fund from a closed-end to an open-end investment company or to approve transactions constituting a plan of reorganization which adversely affects the holders of MuniPreferred shares are higher than those required by the 1940 Act. The Board of Trustees believes that the provisions of the Declaration relating to such higher votes are in the best interest of the Fund and its shareholders. See the Statement of Additional Information under "Certain Provisions in the Declaration of Trust."

Reference should be made to the Declaration on file with the Securities and Exchange Commission for the full text of these provisions.

REPURCHASE OF FUND SHARES; CONVERSION TO OPEN-END FUND

The Fund is a closed-end investment company and as such its shareholders will not have the right to cause the Fund to redeem their shares. Instead, the common shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), net asset value, call protection, dividend stability, portfolio credit quality, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Because shares of closed-end investment companies may frequently trade at prices lower than net asset value, the Fund's Board of Trustees has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from net asset value in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at net asset value, or the conversion of the Fund to an open-end investment company. The Fund cannot assure you that its Board of Trustees will decide to take any of these actions, or that share repurchases or tender offers will actually reduce market discount.

37

If the Fund converted to an open-end investment company, it would be required to redeem all MuniPreferred shares then outstanding (requiring in turn that it liquidate a portion of its investment portfolio), and the common shares would no longer be listed on the American Stock Exchange. In contrast to a closed-end investment company, shareholders of an open-end investment company may require the company to redeem their shares at any time (except in certain circumstances as authorized by or under the 1940 Act) at their net asset value, less any redemption charge that is in effect at the time of redemption. See the Statement of Additional Information under "Certain Provisions in the Declaration of Trust" for a discussion of the voting requirements applicable to the conversion of the Fund to an open-end investment company.

Before deciding whether to take any action if the common shares trade below net asset value, the Board would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund's portfolio, the impact of any action that might be taken on the Fund or its shareholders, and market considerations. Based on these considerations, even if the Fund's shares should trade at a discount, the Board of Trustees may determine that, in the interest of the Fund and its shareholders, no action should be taken. See the Statement of Additional Information under "Repurchase of Fund Shares; Conversion to Open-End Fund" for a further discussion of possible action to reduce or eliminate such discount to net asset value.

FEDERAL INCOME TAX MATTERS

The discussions below and in the Statement of Additional Information provide general tax information. Because tax laws are complex and often change, you should consult your tax advisor about the tax consequences of an investment in the MuniPreferred shares before making such an investment.

The Fund intends to elect to be treated, and to qualify each year, as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"), and intends to distribute substantially all of its net income and gains to its shareholders. Therefore, it is not expected that the Fund will be subject to any federal income tax. The Fund primarily invests in municipal securities issued by states, cities and local authorities and certain possessions and territories of the United States (such as Puerto Rico or Guam) or in municipal securities whose income is otherwise exempt from regular federal income taxes. Thus, substantially all of the Fund's dividends to you should qualify as "exempt-interest dividends." A shareholder treats an exempt-interest dividend as interest on state and local bonds exempt from regular federal income tax. Federal income tax law imposes an alternative minimum tax with respect to corporations, individuals, trusts and estates. Interest on certain municipal obligations, such as certain private activity bonds is included as an item of tax preference in determining the amount of a taxpayer's alternative minimum taxable income. To the extent that the Fund receives income from such municipal obligations, a portion of the dividends paid by the Fund, although exempt from regular federal income tax, will be taxable to shareholders to the extent that their tax liability is determined under the federal alternative minimum tax. The Fund will annually provide a report indicating the percentage of the Fund's income attributable to municipal obligations subject to the federal alternative minimum tax. In addition, for certain corporations, federal alternative minimum taxable income is increased by 75% of the difference between an alternative measure of income ("adjusted current earnings") and the amount otherwise determined to be the alternative minimum taxable income. Interest on all municipal obligations, and therefore all distributions by the Fund that would otherwise be tax-exempt, is included in calculating a corporation's adjusted current earnings. Certain small corporations are not subject to the alternative minimum tax.

In addition to exempt-interest dividends, the Fund also may distribute to its shareholders amounts that are treated as long-term capital gain or ordinary income. These distributions will generally be taxable to holders of MuniPreferred. The Fund will allocate distributions to shareholders that are treated as tax-exempt interest and as long-term capital gain and ordinary income, if any, among the common shares and MuniPreferred shares in proportion to total dividends paid to each class for the year. The Fund intends to notify MuniPreferred shareholders in advance if it will allocate to them income that is not exempt from regular federal income tax. In certain circumstances, in particular during the Extended Initial Rate Periods for Series T and Series W, the Fund will make payments to MuniPreferred shareholders to offset the federal income tax effects of the taxable distribution. See "Description of MuniPreferred Shares -- Dividends and

38

Dividend Periods -- Gross-up Payments." As long as the Fund qualifies as a regulated investment company, distributions paid by the Fund generally will not be eligible for the dividends-received deduction available to corporations. Although dividends generally will be treated as distributed when paid, dividends declared in October, November or December, payable to shareholders of record on a specified date in one of those months and paid during the following January, will be treated as having been distributed by the Fund (and received by the shareholders) on December 31 of the year declared.

The sale or other disposition of common shares or shares of MuniPreferred of the Fund will normally result in capital gain or loss to shareholders if such shares are held as a capital asset. Present law taxes both long-term and short-term capital gains of corporations at the rates applicable to ordinary income. For non-corporate taxpayers, long-term capital gains are generally subject to reduced rates of taxation. Losses realized by a shareholder on the sale or exchange of shares of the Fund held for six months or less are disallowed to the extent of any distribution of exempt-interest dividends received with respect to such shares, and, if not disallowed, such losses are treated as long-term capital losses to the extent of any distribution of long-term capital gain received (or designated amounts of undistributed capital gain that are treated as received) with respect to such shares. Under certain circumstances, a shareholder's holding period may have to restart after, or may be suspended for, any periods during which the shareholder's risk of loss is diminished as a result of holding one or more other positions in substantially similar or related property, or through certain options or short sales. Any loss realized on a sale or exchange of shares of the Fund will be disallowed to the extent those shares of the Fund are replaced by other substantially identical shares of the Fund within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares. In that event, the basis of the replacement shares of the Fund will be adjusted to reflect the disallowed loss.

The Code provides that interest on indebtedness incurred or continued to purchase or carry the Fund's shares to which exempt-interest dividends are allocated is not deductible. Under rules used by the Internal Revenue Service for determining when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase or ownership of shares may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of such shares.

The Fund is required in certain circumstances to withhold a portion of dividends and certain other payments paid to certain holders of the Fund's shares who do not furnish to the Fund their correct taxpayer identification number (in the case of individuals, their social security number) and certain certifications, or who are otherwise subject to backup withholding.

The Jobs and Growth Tax Relief Reconciliation Act of 2003 (the "Act") reduced the maximum rate of tax on long-term capital gains of noncorporate investors from 20% to 15%. The Act also reduced to 15% the maximum rate of tax on "qualified dividend income" received by noncorporate shareholders who satisfy certain holding period and other requirements. None of the Fund's distributions are expected to be eligible for treatment as qualified dividend income. Without further legislative change, the rate reductions enacted by the Act will lapse, and the previous rates will be reinstated, for taxable years beginning on or after January 1, 2009.

The Statement of Additional Information contains a more detailed summary of the federal income tax rules that apply to the Fund and its shareholders. Legislative, judicial or administrative action may change the tax rules that apply to the Fund or its shareholders and any such change may be retroactive. You should consult with your tax advisor about the federal, foreign, state and local tax consequences of an investment in the Fund before making such investment.

The Underwriting Agreement provides that the obligations of the underwriters are subject to certain conditions, including the absence of any materially adverse change in the Fund's business and the receipt of certain certificates, opinions and letters from the Fund and the Fund's attorneys and independent accountants. The nature of the underwriters' obligation is such that they are committed to purchase all MuniPreferred shares offered hereby if any of the MuniPreferred shares are purchased.

The underwriters have advised the Fund that the underwriters propose to offer some of the MuniPreferred shares directly to investors at the offering price of $25,000 per MuniPreferred share, and may offer some of the MuniPreferred shares to certain dealers at the offering price less a concession not in excess of $ per MuniPreferred share, and such dealers may reallow a concession not in excess of $ per MuniPreferred share on sales to certain other dealers. The sales load of $ is equal to % of the offering price. The MuniPreferred shares are offered by the Underwriters, subject to prior sale, when, as and if delivered to and accepted by the Underwriters, and subject to their right to reject orders in whole or in part.

The Fund anticipates that the underwriters may from time to time act as brokers or dealers in executing the Fund's portfolio transactions after they have ceased to be underwriters and, subject to certain restrictions, may act as brokers while they are underwriters. The underwriters are active underwriters of, and dealers in, securities and act as market makers in a number of such securities, and therefore can be expected to engage in portfolio transactions with, and perform services for, the Fund. Nuveen may engage in these transactions only in compliance with the 1940 Act.

The Fund anticipates that the underwriters or their respective affiliates may, from time to time, act in auctions as Broker-Dealers and receive fees as set forth under "The Auction" and in the Statement of Additional Information.

The Fund and Nuveen Advisory have agreed to indemnify the underwriters against certain liabilities, including liabilities arising under the Securities Act of 1933, or to contribute payments the underwriters may be required to make for any of those liabilities. Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Fund pursuant to the foregoing provisions, or otherwise, the Fund has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Fund of expenses incurred or paid by a director, officer or controlling person of the Fund in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Fund will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Nuveen, 333 West Wacker Drive, Chicago, Illinois, 60606, one of the underwriters, and Nuveen Advisory are each wholly owned subsidiaries of Nuveen Investments, Inc.

INVESTMENT OBJECTIVES

The Fund's primary investment objective is to provide high current income exempt from regular federal income tax. The Fund's secondary investment objective is to seek attractive total return consistent with its primary objective. Any capital appreciation realized by the Fund will generally result in the distribution of taxable capital gains to shareholders. The Fund seeks to achieve its investment objectives by investing in municipal securities that Nuveen Advisory believes are underrated and undervalued. The Fund cannot assure you that it will achieve its investment objectives. The Fund's investment objectives are fundamental policies of the Fund.

INVESTMENT RESTRICTIONS

Except as described below, the Fund, as a fundamental policy, may not, without the approval of the holders of a majority of the outstanding common shares and, if issued, MuniPreferred shares (as hereinafter defined) voting together as a single class, and of the holders of a majority of the outstanding MuniPreferred shares voting as a separate class:

(1) Under normal circumstances, invest less than 80% of the Fund's net assets (plus any borrowings for investment purposes) in investments the income from which is exempt from regular federal income tax;

(2) Issue senior securities, as defined in the Investment Company Act of 1940, other than MuniPreferred shares, except to the extent permitted under the Investment Company Act of 1940 and except as otherwise described in the prospectus;

(3) Borrow money, except as permitted by the Investment Company Act of 1940 and exemptive orders granted under the Investment Company Act of 1940;

(4) Act as underwriter of another issuer's securities, except to the extent that the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933 in connection with the purchase and sale of portfolio securities;

(5) Invest more than 25% of its total assets in securities of issuers in any one industry; provided, however, that such limitation shall not apply to municipal securities other than those municipal securities backed only by the assets and revenues of non-governmental users;

(6) Purchase or sell real estate, but this shall not prevent the Fund from investing in municipal securities secured by real estate or interests therein or foreclosing upon and selling such real estate;

(7) Purchase or sell physical commodities unless acquired as a result of ownership of securities or other instruments (but this shall not prevent the Fund from purchasing or selling options, futures contracts or derivative instruments or from investing in securities or other instruments backed by physical commodities);

(8) Make loans, except as permitted by the Investment Company Act of 1940 and exemptive orders granted under the Investment Company Act of 1940;

(9) With respect to 75% of the value of the Fund's total assets, purchase any securities (other than obligations issued or guaranteed by the United States government or by its agencies or instrumentalities), if as a result more than 5% of the Fund's total assets would then be

S-3

invested in securities of a single issuer or if as a result the Fund would hold more than 10% of the outstanding voting securities of any single issuer; and

(10) Invest in securities other than municipal securities and short-term securities, as described in the prospectus, except the Fund may invest up to 5% of its net assets in tax-exempt or taxable fixed-income or equity securities for the purpose of acquiring control of an issuer whose municipal securities (a) the Fund already owns and
(b) have deteriorated or are expected shortly to deteriorate significantly in credit quality, provided Nuveen Advisory determines such investment should enable the Fund to maximize better its existing investment in such issuer. For purposes of the foregoing and "Description of Shares--MuniPreferred Shares--Voting Rights" below, "majority of the outstanding," when used with respect to particular shares of the Fund, means (i) 67% or more of the shares present at a meeting, if the holders of more than 50% of the shares are present or represented by proxy, or (ii) more than 50% of the shares, whichever is less.

For the purpose of applying the limitation set forth in subparagraph
(9) above, an issuer shall be deemed the sole issuer of a security when its assets and revenues are separate from other governmental entities and its securities are backed only by its assets and revenues. Similarly, in the case of a non-governmental issuer, such as an industrial corporation or a privately owned or operated hospital, if the security is backed only by the assets and revenues of the non-governmental issuer, then such non-governmental issuer would be deemed to be the sole issuer. Where a security is also backed by the enforceable obligation of a superior or unrelated governmental or other entity (other than a bond insurer), it shall also be included in the computation of securities owned that are issued by such governmental or other entity. Where a security is guaranteed by a governmental entity or some other facility, such as a bank guarantee or letter of credit, such a guarantee or letter of credit would be considered a separate security and would be treated as an issue of such government, other entity or bank. When a municipal security is insured by bond insurance, it shall not be considered a security that is issued or guaranteed by the insurer; instead, the issuer of such municipal security will be determined in accordance with the principles set forth above. The foregoing restrictions do not limit the percentage of the Fund's assets that may be invested in municipal securities insured by any given insurer.

Under the Investment Company Act of 1940, the Fund may invest only up to 10% of its Managed Assets in the aggregate in shares of other investment companies and only up to 5% of its Managed Assets in any one investment company, provided the investment does not represent more than 3% of the voting stock of the acquired investment company at the time such shares are purchased. As a stockholder in any investment company, the Fund will bear its ratable share of that investment company's expenses, and will remain subject to payment of the Fund's management, advisory and administrative fees with respect to assets so invested. Holders of common shares would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. As described in the prospectus in the section entitled "Risk Factors", the net asset value and market value of leveraged shares will be more volatile and the yield to shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

In addition to the foregoing fundamental investment policies, the Fund is also subject to the following non-fundamental restrictions and policies, which may be changed by the Board of Trustees. The Fund may not:

(1) Sell securities short, unless the Fund owns or has the right to obtain securities equivalent in kind and amount to the securities sold at no added cost, and provided that transactions in options, futures contracts, options on futures contracts, or other derivative instruments are not deemed to constitute selling securities short.

S-4

(2) Purchase securities of open-end or closed-end investment companies except in compliance with the Investment Company Act of 1940 or any exemptive relief obtained thereunder.

(3) Enter into futures contracts or related options or forward contracts, if more than 30% of the Fund's net assets would be represented by futures contracts or more than 5% of the Fund's net assets would be committed to initial margin deposits and premiums on futures contracts and related options.

(4) Purchase securities when borrowings exceed 5% of its total assets if and so long as MuniPreferred shares are outstanding.

(5) Purchase securities of companies for the purpose of exercising control, except as otherwise permitted in the Fund's prospectus and statement of additional information.

(6) Invest in inverse floating rate securities (which are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and which represent in effect a leveraged investment in an underlying municipal security).

The restrictions and other limitations set forth above will apply only at the time of purchase of securities and will not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of an acquisition of securities.

The Fund applied for ratings for its preferred shares (called "MuniPreferred" herein) from Moody's and S&P. In order to obtain and maintain the required ratings, the Fund is required to comply with investment quality, diversification and other guidelines established by such rating agencies. The guidelines are more restrictive than the restrictions set forth above, including with respect to the Fund's hedging strategies. Moody's and S&P receive fees in connection with their ratings issuances.

INVESTMENT POLICIES AND TECHNIQUES

The following information supplements the discussion of the Fund's investment objectives, policies, and techniques that are described in the Fund's prospectus.

INVESTMENT PHILOSOPHY AND PROCESS

INVESTMENT PHILOSOPHY. Nuveen Advisory believes that the unique tax treatment of municipal securities and the structural characteristics in the municipal securities market create attractive opportunities to enhance the after-tax total return and diversification of the investment portfolios of taxable investors. Nuveen Advisory believes that these unique characteristics also present unique risks that may be managed to realize the benefits of the asset class.

After-Tax Income Potential: The primary source of total return from municipal securities comes from the tax-exempt income derived therefrom. Nuveen Advisory believes that, at acceptable levels of credit risk and maturity principal risk, the municipal securities market offers the potential for higher after-tax income when compared with other fixed income markets.

Managing Multi-Faceted Risks: Risk in the municipal securities market is derived from multiple sources, including credit risk at the issuer and sector levels, structural risks such as call risk, yield curve risk, and legislative and tax-related risks. Nuveen Advisory believes that managing these risks at both the

S-5

individual security and Fund portfolio levels is an important element of realizing the after-tax income and total return potential of the asset class.

Opportunities for Diversification: As of December 31, 2002, the municipal securities market aggregated approximately $1.76 trillion, and over 50,000 issuers, collectively with a wide array of financing purposes, security terms, offering structures, and credit quality. Nuveen Advisory believes that the size and depth of the municipal securities market may facilitate the creation of a diversified portfolio that reduces exposure to the risks of individual issuers and may lower correlations to other credit and market risks within an investor's overall portfolio.

Market Inefficiencies: Nuveen Advisory believes that the scale and intricacy of the municipal securities market often results in pricing anomalies and other inefficiencies that can be identified and capitalized on through trading strategies.

INVESTMENT PROCESS. Nuveen Advisory believes that a bottom-up, value-oriented investment strategy that seeks to identify underrated and undervalued securities and sectors is positioned to capture the opportunities inherent in the municipal securities market and potentially outperform the general municipal securities market over time. The primary elements of Nuveen Advisory's investment process are:

Credit Analysis and Surveillance: Nuveen Advisory focuses on bottom-up, fundamental analysis of municipal securities issuers. Analysts screen each sector for issuers that meet the fundamental tests of creditworthiness and favor those securities with demonstrable growth potential, solid coverage of debt service and a priority lien on hard assets, dedicated revenue streams or tax resources. As part of Nuveen Advisory's overall risk management process, analysts actively monitor the credit quality of portfolio holdings.

Sector Analysis: Organized by sector, analysts continually assess the key issues and trends affecting each sector in order to maintain a sector outlook. Evaluating such factors as historical default rates and average credit spreads within each sector, analysts provide top-down analysis that supports decisions to overweight or underweight a given sector in a portfolio.

Diversification: Nuveen Advisory seeks to invest in a large number of sectors, states and specific issuers in order to help insulate a portfolio from events that affect any individual industry, geographic location or credit. Portfolio managers normally seek to limit exposure to individual credits over the long-term. Portfolio managers also seek to diversify other portfolio level risks, including exposure to calls, and to manage a portfolio's interest rate sensitivity within tolerance bands relative to the relevant benchmark.

Trading Strategies: Through its trading strategies, Nuveen Advisory seeks to enhance portfolio value by trading to take advantage of inefficiencies found in the municipal market. This may entail selling issues Nuveen Advisory deems to be overvalued and purchasing issues Nuveen Advisory considers to be undervalued.

Sell Discipline: Nuveen Advisory generally sells securities when it (i) determines a security has become overvalued or over-rated, (ii) identifies credit deterioration, or (iii) modifies a portfolio strategy, such as sector allocation. Nuveen Advisory may also sell securities when such securities exceed the portfolio's diversification targets.

INVESTMENT POLICIES

Under normal circumstances, the Fund will invest its Managed Assets in a portfolio of municipal securities that pay interest that is exempt from regular federal income tax. It is a fundamental policy of

S-6

the Fund that its investment in municipal securities paying interest that is exempt from regular federal income tax will, under normal circumstances, comprise at least 80% of the Fund's Managed Assets.

Under normal circumstances, and except for the temporary investments described below, the Fund expects to be fully invested (at least 95% of its Managed Assets) in such tax-exempt municipal securities described above. Up to 30% of the Fund's Managed Assets may be invested in municipal securities that pay interest that is taxable under the federal alternative minimum tax applicable to individuals. For a discussion of how the federal alternative minimum tax may affect shareholders, see "Federal Income Tax Matters."

o The Fund will invest at least 50% of its Managed Assets in investment grade quality municipal securities. A security is considered investment grade quality if it is rated within the four highest grades (Baa or BBB or better by Moody's, S&P or Fitch) by all NRSROs that rate such security, or if it is unrated but judged to be of comparable quality by Nuveen Advisory.

o The Fund may invest up to 50% of its Managed Assets in municipal securities that at the time of investment are rated below investment grade. Below investment grade quality municipal securities include those municipal securities that are rated investment grade by one or more NRSROs but rated below investment grade by at least one NRSRO. No more than 5% of the Fund's Managed Assets may be invested in municipal securities rated below B3/B- or that are unrated but judged to be of comparable quality by Nuveen Advisory. This means that the Fund may invest in municipal securities that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition (such securities are commonly referred to as distressed securities).

o The Fund anticipates that, upon the full investment of the net proceeds from this offering (which is expected to occur within two to three months following the closing of this offering), it will have invested approximately 55% to 65% of its Managed Assets in investment grade municipal securities and approximately 35% to 45% of its Managed Assets in below investment grade municipal securities. The relative percentages of the value of the Fund's Managed Assets attributable to investment grade municipal securities and to below investment grade municipal securities could change over time as a result of rebalancing the Fund's assets by Nuveen Advisory, market value fluctuations and other events.

Municipal securities are either general obligation or revenue bonds and typically are issued to finance public projects (such as roads or public buildings), to pay general operating expenses, or to refinance outstanding debt. Municipal securities may also be issued for private activities, such as housing, medical and educational facility construction, or for privately owned industrial development and pollution control projects. General obligation bonds are backed by the full faith and credit, or taxing authority, of the issuer and may be repaid from any revenue source; revenue bonds may be repaid only from the revenues of a specific facility or source. The Fund may also purchase municipal securities that represent lease obligations, municipal notes, pre-refunded municipal securities, private activity bonds, tender option bonds and other forms of municipal securities.

Municipal securities of below investment grade quality (Ba/BB or below) are commonly referred to as junk bonds. Issuers of securities rated Ba/BB or B are regarded as having current capacity to make principal and interest payments but are subject to business, financial or economic conditions which could adversely affect such payment capacity. Municipal securities rated Baa or BBB are considered "investment grade" securities; municipal securities rated Baa are considered medium grade obligations which lack outstanding investment characteristics and have speculative characteristics, while municipal

S-7

securities rated BBB are regarded as having adequate capacity to pay principal and interest. Municipal securities rated Aaa or AAA in which the Fund may invest may have been so rated on the basis of the existence of insurance guaranteeing the timely payment, when due, of all principal and interest. Municipal securities rated below investment grade quality are obligations of issuers that are considered predominately speculative with respect to the issuer's capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Municipal securities rated below investment grade tend to be less marketable than higher-quality securities because the market for them is less broad. The market for unrated municipal securities is even narrower. During periods of thin trading in these markets, the spread between bid and asked prices is likely to increase significantly and the Fund may have greater difficulty selling its portfolio securities. The Fund will be more dependent on Nuveen Advisory's research and analysis when investing in these securities.

The Fund may invest in distressed securities, which are securities issued by companies that are involved in bankruptcy or insolvency proceedings or are experiencing other financial difficulties at the time of acquisition by the Fund. The issuers of such securities may be in transition, out of favor, financially leveraged or troubled, or potentially troubled, and may be or have recently been involved in major strategic actions, restructurings, bankruptcy, reorganization or liquidation. These characteristics of these companies can cause their securities to be particularly risky, although they also may offer the potential for high returns. These companies' securities may be considered speculative, and the ability of the companies to pay their debts on schedule could be affected by adverse interest rate movements, changes in the general economic climate, economic factors affecting a particular industry or specific developments within the companies. Distressed securities frequently do not produce income while they are outstanding and may require the Fund to bear certain extraordinary expenses in order to protect and recover its investment.

Investments in lower rated or unrated securities may present special tax issues for the Fund to the extent that the issuers of these securities default on their obligations pertaining thereto, and the federal income tax consequences to the Fund as a holder of such distressed securities may not be clear.

A general description of Moody's, S&P's and Fitch's ratings of municipal securities is set forth in Appendix B hereto. The ratings of Moody's, S&P and Fitch represent their opinions as to the quality of the municipal securities they rate. It should be emphasized, however, that ratings are general and are not absolute standards of quality. Consequently, municipal securities with the same maturity, coupon and rating may have different yields while obligations of the same maturity and coupon with different ratings may have the same yield.

The Fund will primarily invest in municipal securities with long-term maturities in order to maintain a weighted average maturity of 15 to 30 years, but the weighted average maturity of obligations held by the Fund may be shorter, depending on market conditions. As a result, the Fund's portfolio at any given time may include both long-term and intermediate-term municipal securities. Moreover, during temporary defensive periods (e.g., times when, in Nuveen Advisory's opinion, temporary imbalances of supply and demand or other temporary dislocations in the tax-exempt securities market adversely affect the price at which long-term or intermediate-term municipal securities are available), and in order to keep the Fund's cash fully invested, including the period during which the net proceeds of the offering are being invested, the Fund may invest any percentage of its net assets in short-term investments including high quality, short-term securities that may be either tax-exempt or taxable and up to 10% of its Managed Assets in securities of other open or closed-end investment companies that invest primarily in municipal securities of the type in which the Fund may invest directly. The Fund intends to invest in taxable short-term investments only in the event that suitable tax-exempt short-term investments are not available at reasonable prices and yields. Tax-exempt short-term investments include various obligations issued by

S-8

state and local governmental issuers, such as tax-exempt notes (bond anticipation notes, tax anticipation notes and revenue anticipation notes or other such municipal bonds maturing in three years or less from the date of issuance) and municipal commercial paper. The Fund will invest only in taxable short-term investments which are U.S. government securities or securities rated within the highest grade by Moody's, S&P or Fitch, and which mature within one year from the date of purchase or carry a variable or floating rate of interest. See Appendix B for a general description of Moody's, S&P's and Fitch's ratings of securities in such categories. Taxable short-term investments of the Fund may include certificates of deposit issued by U.S. banks with assets of at least $1 billion, or commercial paper or corporate notes, bonds or debentures with a remaining maturity of one year or less, or repurchase agreements. See "Other Investment Policies and Techniques--Repurchase Agreements." To the extent the Fund invests in taxable investments, the Fund will not at such times be in a position to achieve its investment objective of tax-exempt income.

The foregoing policies as to ratings of portfolio investments will apply only at the time of the purchase of a security, and the Fund will not be required to dispose of securities in the event Moody's, S&P or Fitch downgrades its assessment of the credit characteristics of a particular issuer.

Obligations of issuers of municipal securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Bankruptcy Reform Act of 1978. In addition, the obligations of such issuers may become subject to the laws enacted in the future by Congress, state legislatures or referenda extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations or upon municipalities to levy taxes. There is also the possibility that, as a result of legislation or other conditions, the power or ability of any issuer to pay, when due, the principal of and interest on its municipal securities may be materially affected.

The Fund presently intends to limit its investment in tobacco settlement bonds to no more than 10% of its Managed Assets. In addition, the Fund will not invest in inverse floating rate securities, which are securities that pay interest at rates that vary inversely with changes in prevailing short-term tax-exempt interest rates and which represent in effect a leveraged investment in an underlying municipal security.

Subject to guidelines which may be imposed in connection with the Fund's seeking an investment grade rating on the MuniPreferred shares, the Fund may invest a significant portion of its Managed Assets in broad segments of the municipal securities market, such as revenue obligations of hospitals and other health care facilities, special taxing districts, securities issued to finance charter schools and other private educational facilities, municipal utility securities, industrial development bonds and other private activity bonds. Subject to the availability of suitable investment opportunities, Nuveen Advisory will attempt to minimize the sensitivity of the Fund's portfolio to credit and other risks associated with a particular sector or industry. However, if the Fund invests a significant portion of its Managed Assets in the segments noted above, the Fund will be more susceptible to economic, business, political, regulatory and other developments generally affecting issuers in such segments of the municipal securities market. To the extent that the Fund focuses its Managed Assets in the hospital and healthcare facilities sector, the Fund will be subject to risks associated with such sector, including adverse government regulation and reduction in reimbursement rates, as well as government approval of products and services and intense competition. Securities issued to finance charter schools and other private educational facilities will be subject to various risks, including the reversal of legislation authorizing or funding charter schools, the failure to renew or secure a charter, the failure of a funding entity to appropriate necessary funds and competition from alternatives such as voucher programs. Issuers of municipal utility securities can be significantly affected by government regulation, financing difficulties, supply and demand of services or fuel and natural resource conservation.

S-9

Up to 30% of the Fund's Managed Assets may be invested in municipal securities subject to the federal alternative minimum tax applicable to individuals. Special federal alternative minimum tax rules apply to corporate investors. For a discussion of how the federal alternative minimum tax may affect shareholders, see "Federal Income Tax Matters."

Upon Nuveen Advisory's recommendation, during temporary defensive periods and in order to keep the Fund's cash fully invested, including the period during which the net proceeds of the offering of common shares or MuniPreferred shares are being invested, the Fund may deviate from its investment objectives and invest up to 100% of its Managed Assets in short-term investments including high quality, short-term securities that may be either tax-exempt or taxable. To the extent the Fund invests in taxable short-term investments, the Fund will not at such times be in a position to achieve that portion of its investment objective of seeking current income exempt from regular federal income tax. For further information, see, "Short-Term Investments" below.

Municipal Leases and Certificates of Participation. Also included within the general category of municipal securities described in the Fund's prospectus are municipal leases, certificates of participation in such lease obligations or installment purchase contract obligations (hereinafter collectively called "Municipal Lease Obligations") of municipal authorities or entities. Although a Municipal Lease Obligation does not constitute a general obligation of the municipality for which the municipality's taxing power is pledged, a Municipal Lease Obligation is ordinarily backed by the municipality's covenant to budget for, appropriate and make the payments due under the Municipal Lease Obligation. However, certain Municipal Lease Obligations contain "non-appropriation" clauses which provide that the municipality has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. In the case of a "non-appropriation" lease, the Fund's ability to recover under the lease in the event of non-appropriation or default will be limited solely to the repossession of the leased property, without recourse to the general credit of the lessee, and disposition or releasing of the property might prove difficult. In order to reduce this risk, the Fund will only purchase Municipal Lease Obligations where Nuveen Advisory believes the issuer has a strong incentive to continue making appropriations until maturity.

Pre-Refunded Municipal Securities. The principal of and interest on pre-refunded municipal securities are no longer paid from the original revenue source for the securities. Instead, the source of such payments is typically an escrow fund consisting of U.S. government securities. The assets in the escrow fund are derived from the proceeds of refunding bonds issued by the same issuer as the pre-refunded municipal securities. Issuers of municipal securities use this advance refunding technique to obtain more favorable terms with respect to securities that are not yet subject to call or redemption by the issuer. For example, advance refunding enables an issuer to refinance debt at lower market interest rates, restructure debt to improve cash flow or eliminate restrictive covenants in the indenture or other governing instrument for the pre-refunded municipal securities. However, except for a change in the revenue source from which principal and interest payments are made, the pre-refunded municipal securities remain outstanding on their original terms until they mature or are redeemed by the issuer.

Private Activity Bonds. Private activity bonds, formerly referred to as industrial development bonds, are issued by or on behalf of public authorities to obtain funds to provide privately operated housing facilities, airport, mass transit or port facilities, sewage disposal, solid waste disposal or hazardous waste treatment or disposal facilities and certain local facilities for water supply, gas or electricity. Other types of private activity bonds, the proceeds of which are used for the construction, equipment, repair or improvement of privately operated industrial or commercial facilities, may constitute municipal securities, although the current federal tax laws place substantial limitations on the size of such issues. The Fund's distributions of its interest income from private activity bonds may subject certain investors to the federal alternative minimum tax.

S-10

Tender Option Bonds. A tender option bond is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term, tax-exempt rates. The bond is typically issued with the agreement of a third party, such as a bank, broker-dealer or other financial institution, which grants the security holders the option, at periodic intervals, to tender their securities to the institution and receive the face value thereof. As consideration for providing the option, the financial institution receives periodic fees equal to the difference between the bond's fixed coupon rate and the rate, as determined by a remarketing or similar agent at or near the commencement of such period, that would cause the securities, coupled with the tender option, to trade at par on the date of such determination. Thus, after payment of this fee, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. However, an institution will not be obligated to accept tendered bonds in the event of certain defaults or a significant downgrade in the credit rating assigned to the issuer of the bond. The Fund intends to invest in tender option bonds the interest on which will, in the opinion of bond counsel, counsel for the issuer of interests therein or counsel selected by Nuveen Advisory, be exempt from regular federal income tax. However, because there can be no assurance that the IRS will agree with such counsel's opinion in any particular case, there is a risk that the Fund will not be considered the owner of such tender option bonds and thus will not be entitled to treat such interest as exempt from such tax. Additionally, the federal income tax treatment of certain other aspects of these investments, including the proper tax treatment of tender option bonds and the associated fees in relation to various regulated investment company tax provisions, is unclear. The Fund intends to manage its portfolio in a manner designed to eliminate or minimize any adverse impact from the tax rules applicable to these investments.

Special Taxing Districts. Special taxing districts are organized to plan and finance infrastructure development to induce residential, commercial and industrial growth and redevelopment. The bond financing methods such as tax increment finance, tax assessment, special services district and Mello-Roos bonds, are generally payable solely from taxes or other revenues attributable to the specific projects financed by the bonds without recourse to the credit or taxing power of related or overlapping municipalities. They often are exposed to real estate development-related risks and can have more taxpayer concentration risk than general tax-supported bonds, such as general obligation bonds. Further, the fees, special taxes, or tax allocations and other revenues that are established to secure such financings are generally limited as to the rate or amount that may be levied or assessed and are not subject to increase pursuant to rate covenants or municipal or corporate guarantees. The bonds could default if development failed to progress as anticipated or if larger taxpayers failed to pay the assessments, fees and taxes as provided in the financing plans of the districts.

SHORT-TERM INVESTMENTS

SHORT-TERM TAXABLE FIXED INCOME SECURITIES

For temporary defensive purposes or to keep cash on hand fully invested, the Fund may invest up to 100% of its net assets in cash equivalents and short- term taxable fixed-income securities, although the Fund intends to invest in taxable short-term investments only in the event that suitable tax-exempt short- term investments are not available at reasonable prices and yields. Short-term taxable fixed income investments are defined to include, without limitation, the following:

(1) U.S. government securities, including bills, notes and bonds differing as to maturity and rates of interest that are either issued or guaranteed by the U.S. Treasury or by U.S. government agencies or instrumentalities. U.S. government agency securities include securities issued by (a) the Federal Housing Administration, Farmers Home Administration, Export-Import Bank of the United States, Small Business Administration, and the Government National Mortgage Association, whose securities are supported by the full faith and credit of the United

S-11

States; (b) the Federal Home Loan Banks*, Federal Intermediate Credit Banks, and the Tennessee Valley Authority, whose securities are supported by the right of the agency to borrow from the U.S. Treasury;
(c) the Federal National Mortgage Association*, whose securities are supported by the discretionary authority of the U.S. government to purchase certain obligations of the agency or instrumentality; and (d) the Student Loan Marketing Association, whose securities are supported only by its credit. While the U.S. government provides financial support to such U.S. government-sponsored agencies or instrumentalities, no assurance can be given that it always will do so since it is not so obligated by law. The U.S. government, its agencies, and instrumentalities do not guarantee the market value of their securities. Consequently, the value of such securities may fluctuate.

(2) Certificates of Deposit issued against funds deposited in a bank or a savings and loan association. Such certificates are for a definite period of time, earn a specified rate of return, and are normally negotiable. The issuer of a certificate of deposit agrees to pay the amount deposited plus interest to the bearer of the certificate on the date specified thereon. Under current FDIC regulations, the maximum insurance payable as to any one certificate of deposit is $100,000; therefore, certificates of deposit purchased by the Fund may not be fully insured.

(3) Repurchase agreements, which involve purchases of debt securities. At the time the Fund purchases securities pursuant to a repurchase agreement, it simultaneously agrees to resell and redeliver such securities to the seller, who also simultaneously agrees to buy back the securities at a fixed price and time. This assures a predetermined yield for the Fund during its holding period, since the resale price is always greater than the purchase price and reflects an agreed-upon market rate. Such actions afford an opportunity for the Fund to invest temporarily available cash. The Fund may enter into repurchase agreements only with respect to obligations of the U.S. government, its agencies or instrumentalities; certificates of deposit; or bankers' acceptances in which the Fund may invest. Repurchase agreements may be considered loans to the seller, collateralized by the underlying securities. The risk to the Fund is limited to the ability of the seller to pay the agreed-upon sum on the repurchase date; in the event of default, the repurchase agreement provides that the Fund is entitled to sell the underlying collateral. If the seller defaults under a repurchase agreement when the value of the underlying collateral is less than the repurchase price, the Fund could incur a loss of both principal and interest. Nuveen Advisory monitors the value of the collateral at the time the action is entered into and at all times during the term of the repurchase agreement. Nuveen Advisory does so in an effort to determine that the value of the collateral always equals or exceeds the agreed-upon repurchase price to be paid to the Fund. If the seller were to be subject to a federal bankruptcy proceeding, the ability of the Fund to liquidate the collateral could be delayed or impaired because of certain provisions of the bankruptcy laws.

(4) Commercial paper, which consists of short-term unsecured promissory notes, including variable rate master demand notes issued by corporations to finance their current operations. Master demand notes are direct lending arrangements between the Fund and a corporation. There is no secondary market for such notes. However, they are redeemable by the Fund at any time. Nuveen Advisory will consider the financial condition of the corporation (e.g., earning power, cash flow, and other liquidity measures) and will continuously monitor the corporation's ability to meet all of its financial obligations, because the Fund's liquidity might be impaired if the corporation were unable to pay principal and interest on demand. Investments in


* These securities are not backed by the full faith and credit of the United States Government.

S-12

commercial paper will be limited to commercial paper rated in the highest categories by a major rating agency and which mature within one year of the date of purchase or carry a variable or floating rate of interest.

SHORT-TERM TAX-EXEMPT MUNICIPAL SECURITIES

Short-term tax-exempt municipal securities are securities that are exempt from regular federal income tax and mature within three years or less from the date of issuance. Short-term tax-exempt municipal income securities are defined to include, without limitation, the following:

Bond Anticipation Notes ("BANs") are usually general obligations of state and local governmental issuers which are sold to obtain interim financing for projects that will eventually be funded through the sale of long-term debt obligations or bonds. The ability of an issuer to meet its obligations on its BANs is primarily dependent on the issuer's access to the long-term municipal bond market and the likelihood that the proceeds of such bond sales will be used to pay the principal and interest on the BANs.

Tax Anticipation Notes ("TANs") are issued by state and local governments to finance the current operations of such governments. Repayment is generally to be derived from specific future tax revenues. TANs are usually general obligations of the issuer. A weakness in an issuer's capacity to raise taxes due to, among other things, a decline in its tax base or a rise in delinquencies, could adversely affect the issuer's ability to meet its obligations on outstanding TANs.

Revenue Anticipation Notes ("RANs") are issued by governments or governmental bodies with the expectation that future revenues from a designated source will be used to repay the notes. In general, they also constitute general obligations of the issuer. A decline in the receipt of projected revenues, such as anticipated revenues from another level of government, could adversely affect an issuer's ability to meet its obligations on outstanding RANs. In addition, the possibility that the revenues would, when received, be used to meet other obligations could affect the ability of the issuer to pay the principal and interest on RANs.

Construction Loan Notes are issued to provide construction financing for specific projects. Frequently, these notes are redeemed with funds obtained from the Federal Housing Administration.

Bank Notes are notes issued by local government bodies and agencies, such as those described above to commercial banks as evidence of borrowings. The purposes for which the notes are issued are varied but they are frequently issued to meet short-term working capital or capital-project needs. These notes may have risks similar to the risks associated with TANs and RANs.

Tax-Exempt Commercial Paper ("Municipal Paper") represents very short-term unsecured, negotiable promissory notes issued by states, municipalities and their agencies. Payment of principal and interest on issues of municipal paper may be made from various sources, to the extent the funds are available therefrom. Maturities of municipal paper generally will be shorter than the maturities of TANs, BANs or RANs. There is a limited secondary market for issues of Municipal Paper.

Certain municipal securities may carry variable or floating rates of interest whereby the rate of interest is not fixed but varies with changes in specified market rates or indices, such as a bank prime rate or a tax-exempt money market index.

While the various types of notes described above as a group represent the major portion of the short-term tax-exempt note market, other types of notes are available in the marketplace and the Fund may invest in such other types of notes to the extent permitted under its investment objectives, policies

S-13

and limitations. Such notes may be issued for different purposes and may be secured differently from those mentioned above.

HEDGING STRATEGIES

The Fund may periodically engage in hedging transactions. Hedging is a term used for various methods of seeking to preserve portfolio capital value by offsetting price changes in one investment through making another investment whose price should tend to move in the opposite direction. It may be desirable and possible in various market environments partially to hedge the portfolio against fluctuations in market value due to interest rate fluctuations by investment in financial futures and index futures as well as related put and call options on such instruments. Both parties entering into an index or financial futures contract are required to post an initial deposit of 1% to 5% of the total contract price. Typically, option holders enter into offsetting closing transactions to enable settlement in cash rather than take delivery of the position in the future of the underlying security. The Fund will only sell covered futures contracts, which means that the Fund segregates assets equal to the amount of the obligations.

These transactions present certain risks. In particular, the imperfect correlation between price movements in the futures contract and price movements in the securities being hedged creates the possibility that losses on the hedge by a Fund may be greater than gains in the value of the securities in the Fund's portfolio. In addition, futures and options markets may not be liquid in all circumstances. As a result, in volatile markets, the Fund may not be able to close out the transaction without incurring losses substantially greater than the initial deposit. Finally, the potential deposit requirements in futures contracts create an ongoing greater potential financial risk than do options transactions, where the exposure is limited to the cost of the initial premium. Losses due to hedging transactions will reduce yield. Net gains, if any, from hedging and other portfolio transactions will be distributed as taxable distributions to shareholders. The Fund will not make any investment (whether an initial premium or deposit or a subsequent deposit) other than as necessary to close a prior investment if, immediately after such investment, the sum of the amount of its premiums and deposits would exceed 5% of the Fund's net assets. The Fund will invest in these instruments only in markets believed by Nuveen Advisory to be active and sufficiently liquid. Successful implementation of most hedging strategies would generate taxable income. For further information regarding these investment strategies and risks presented thereby, see Appendix B to this Statement of Additional Information.

The Fund may utilize structured notes and similar instruments for investment purposes and also for hedging purposes. Structured notes are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an "embedded index"), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but not ordinarily below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending upon a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index or indices or other assets. Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

Other hedging strategies include using credit default swaps, interest-rate swaps on taxable or tax-exempt indices, forward starting interest rate swaps and options on interest rate swaps. These hedging strategies may also generate taxable income.

S-14

OTHER INVESTMENT POLICIES AND TECHNIQUES

ILLIQUID SECURITIES

The Fund may invest in illiquid securities (i.e., securities that are not readily marketable), including, but not limited to, restricted securities (securities the disposition of which is restricted under the federal securities laws), securities that may be resold only pursuant to Rule 144A under the Securities Act of 1933, as amended (the "Securities Act") that are deemed to be illiquid, and certain repurchase agreements.

Restricted securities may be sold only in privately negotiated transactions or in a public offering with respect to which a registration statement is in effect under the Securities Act. Where registration is required, the Fund may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell a security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Fund might obtain a less favorable price than that which prevailed when it decided to sell. To the extent that the Board of Trustees or its delegatee determines that the price of any illiquid security provided by the pricing service is inappropriate, such security will be priced at a fair value as determined in good faith by the Board of Trustees or its delegatee.

PORTFOLIO TRADING AND TURNOVER RATE

Portfolio trading may be undertaken to accomplish the investment objectives of the Fund in relation to actual and anticipated movements in interest rates. In addition, a security may be sold and another of comparable quality purchased at approximately the same time to take advantage of what Nuveen Advisory believes to be a temporary price disparity between the two securities. Temporary price disparities between two comparable securities may result from supply and demand imbalances where, for example, a temporary oversupply of certain bonds may cause a temporarily low price for such bonds, as compared with other bonds of like quality and characteristics. The Fund may also engage to a limited extent in short-term trading consistent with its investment objectives. Securities may be sold in anticipation of a market decline (a rise in interest rates) or purchased in anticipation of a market rise (a decline in interest rates) and later sold, but the Fund will not engage in trading solely to recognize a gain.

Subject to the foregoing, the Fund will attempt to achieve its investment objectives by prudent selection of municipal bonds with a view to holding them for investment. While there can be no assurance thereof, the Fund anticipates that its annual portfolio turnover rate will generally not exceed 20%. However, the rate of turnover will not be a limiting factor when the Fund deems it desirable to sell or purchase securities. Therefore, depending upon market conditions, the annual portfolio turnover rate of the Fund may exceed 20% in particular years.

OTHER INVESTMENT COMPANIES

The Fund may invest up to 10% of its Managed Assets in securities of other open or closed-end investment companies that invest primarily in municipal securities of the types in which the Fund may invest directly. In addition, the Fund may invest a portion of its Managed Assets in pooled investment vehicles other than investment companies that invest primarily in municipal securities of the types in which the Fund may invest directly. The Fund generally expects that it may invest in other investment companies and/or other pooled investment vehicles either during periods when it has large amounts of uninvested cash, such as the period shortly after the Fund receives the proceeds of the offering of its common shares or MuniPreferred shares, or during periods when there is a shortage of attractive, high-yielding municipal securities available in the market. As a stockholder in an investment company, the Fund will bear its ratable share of that investment company's expenses and would remain subject to

S-15

payment of the Fund's management, advisory and administrative fees with respect to assets so invested. Common Shareholders would therefore be subject to duplicative expenses to the extent the Fund invests in other investment companies. Nuveen Advisory will take expenses into account when evaluating the investment merits of an investment in an investment company relative to available municipal security investments. In addition, the securities of other investment companies may also be leveraged and will therefore be subject to the same leverage risks described herein. As described in the Fund's prospectus, the net asset value and market value of leveraged shares will be more volatile and the yield to shareholders will tend to fluctuate more than the yield generated by unleveraged shares.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may buy and sell municipal securities on a when-issued or delayed delivery basis, making payment or taking delivery at a later date, normally within 15-45 days of the trade date. On such transactions the payment obligation and the interest rate are fixed at the time the buyer enters into the commitment. Beginning on the date the Fund enters into a commitment to purchase securities on a when-issued or delayed delivery basis, the Fund is required under rules of the Commission to maintain in a separate account liquid assets, consisting of cash, cash equivalents or liquid securities having a market value, at all times, of at least equal to the amount of the commitment. Income generated by any such assets which provide taxable income for federal income tax purposes is includable in the taxable income of the Fund. The Fund may enter into contracts to purchase municipal securities on a forward basis (i.e., where settlement will occur more than 60 days from the date of the transaction) only to the extent that the Fund specifically collateralizes such obligations with a security that is expected to be called or mature within sixty days before or after the settlement date of the forward transaction. The commitment to purchase securities on a when-issued, delayed delivery or forward basis may involve an element of risk because no interest accrues on the bonds prior to settlement and at the time of delivery the market value may be less than cost.

REPURCHASE AGREEMENTS

As temporary investments, the Fund may invest in repurchase agreements. A repurchase agreement is a contractual agreement whereby the seller of securities (U.S. government securities or municipal securities) agrees to repurchase the same security at a specified price on a future date agreed upon by the parties. The agreed-upon repurchase price determines the yield during the Fund's holding period. Repurchase agreements are considered to be loans collateralized by the underlying security that is the subject of the repurchase contract. Income generated from transactions in repurchase agreements will be taxable. See "Federal Income Tax Matters" for information relating to the allocation of taxable income between common shares and MuniPreferred shares, if any. The Fund will only enter into repurchase agreements with registered securities dealers or domestic banks that, in the opinion of Nuveen Advisory, present minimal credit risk. The risk to the Fund is limited to the ability of the issuer to pay the agreed-upon repurchase price on the delivery date; however, although the value of the underlying collateral at the time the transaction is entered into always equals or exceeds the agreed-upon repurchase price, if the value of the collateral declines there is a risk of loss of both principal and interest. In the event of default, the collateral may be sold but the Fund might incur a loss if the value of the collateral declines, and might incur disposition costs or experience delays in connection with liquidating the collateral. In addition, if bankruptcy proceedings are commenced with respect to the seller of the security, realization upon the collateral by the Fund may be delayed or limited. Nuveen Advisory will monitor the value of the collateral at the time the transaction is entered into and at all times subsequent during the term of the repurchase agreement in an effort to determine that such value always equals or exceeds the agreed-upon repurchase price. In the event the value of the collateral declines below the repurchase price, Nuveen Advisory will demand additional collateral from the issuer to increase the value of the collateral to at least that of the repurchase price, including interest.

S-16

ZERO COUPON BONDS

The Fund may invest in zero coupon bonds. A zero coupon bond is a bond that does not pay interest for its entire life. When held to its maturity, its return comes from the difference between the purchase price and its maturity value. The market prices of zero coupon bonds are affected to a greater extent by changes in prevailing levels of interest rates and thereby tend to be more volatile in price than securities that pay interest periodically and may be more speculative than such securities. In addition, because the Fund accrues income with respect to these securities prior to the receipt of such interest, it may have to dispose of portfolio securities under disadvantageous circumstances in order to obtain cash needed to pay income dividends in amounts necessary to avoid unfavorable tax consequences.

MANAGEMENT OF THE FUND

TRUSTEES AND OFFICERS

The management of the Fund, including general supervision of the duties performed for the Fund under the Management Agreement, is the responsibility of the Board of Trustees of the Fund. The number of trustees of the Fund is currently set at twelve. None of the trustees who are not "interested" persons of the Fund has ever been a director or employee of, or consultant to, Nuveen or its affiliates. The names and business addresses of the trustees and officers of the Fund, their principal occupations and other affiliations during the past five years, the number of portfolios each oversees and other directorships they hold are set forth below.

The Board of Trustees has five standing committees: the executive committee, the audit committee, the nominating and governance committee, the dividend committee and the valuation committee. Because the Fund is newly organized, none of the committees have met during the Fund's last fiscal year. The executive committee met once prior to the commencement of the Fund's operations.

S-22

Robert P. Bremner, Anne E. Impellizzeri and Timothy R. Schwertfeger, Chair, serve as members of the executive committee of the Board of Trustees of the Fund. The executive committee, which meets between regular meetings of the Board of Trustees, is authorized to exercise all of the powers of the Board of Trustees.

The audit committee monitors the accounting and reporting policies and practices of the Funds, the quality and integrity of the financial statements of the Funds, compliance by the Funds with legal and regulatory requirements and the independence and performance of the external and internal auditors. The members of the audit committee are William J. Schneider, Chair, William E. Bennett, Robert P. Bremner, Lawrence H. Brown, Jack B. Evans, Thomas E. Leafstrand and Peter R. Sawers.

The nominating and governance committee is responsible for Board selection and tenure; selection and review of committees; and Board education and operations. In addition, the committee monitors performance of legal counsel and other service providers; periodically reviews and makes recommendations about any appropriate changes to trustee compensation; and has the resources and authority to discharge its responsibilities--including retaining special counsel and other experts or consultants at the expense of the Fund. In the event of a vacancy on the Board, the nominating and governance committee receives suggestions from various sources as to suitable candidates. Suggestions should be sent in writing to Lorna Ferguson, Vice President for Board Relations, Nuveen Investments, LLC, 333 West Wacker Drive, Chicago, IL 60606. The nominating and governance committee sets appropriate standards and requirements for nominations for new trustees and reserves the right to interview all candidates and to make the final selection of any new trustees. The members of the nominating and governance committee are Robert P. Bremner, Lawrence H. Brown, Jack B. Evans, Anne E. Impellizzeri, William L. Kissick, Thomas E. Leafstrand, Peter R. Sawers, William J. Schneider, Judith M. Stockdale and Sheila W. Wellington.

The dividend committee is authorized to declare distributions on the Fund's shares including, but not limited to, regular and special dividends, capital gains and ordinary income distributions. The members of the dividend committee are Timothy R. Schwertfeger, Chair, Lawrence H. Brown, Jack B. Evans and Thomas E. Leafstrand.

The valuation committee oversees the Fund's Pricing Procedures including, but not limited to, the review and approval of fair value pricing determinations made by Nuveen's Valuation Group. The members of the valuation committee are Lawrence H. Brown, Thomas E. Leafstrand and Judith M. Stockdale.

Trustees Bennett, Evans, Kissick, Leafstrand, Schwertfeger and Wellington are directors or trustees, as the case may be, of 30 Nuveen open-end funds and 93 Nuveen closed-end funds managed by Nuveen Advisory and 6 open-end funds and 13 closed-end funds managed by Nuveen Institutional Advisory Corp. Trustees Bremner, Brown, Impellizzeri, Sawyers, Schneider and Stockdale are also directors or trustees, as the case may be, of 30 open-end and 93 closed-end funds managed by Nuveen Advisory and 6 open-end funds and 12 closed-end funds managed by Nuveen Institutional Advisory Corp. Mr. Schwertfeger.

None of the independent trustees, nor any of their immediate family members, has ever been a director, officer, or employee of, or a consultant to, Nuveen Advisory, Nuveen or their affiliates. In addition, none of the independent trustees owns beneficially or of record, any security of Nuveen Advisory, Nuveen or any person (other than a registered investment company) directly or indirectly controlling, controlled by or under common control with Nuveen Advisory or Nuveen.

S-23

The Common Shareholders of the Fund will elect trustees at the next annual meeting of Common Shareholders, unless any MuniPreferred shares are outstanding at that time, in which event holders of MuniPreferred shares, voting as a separate class, will elect two trustees and the remaining trustees shall be elected by Common Shareholders and holders of MuniPreferred shares, voting together as a single class. Holders of MuniPreferred shares will be entitled to elect a majority of the Fund's trustees under certain circumstances. See "Description of Shares--MuniPreferred Shares--Voting Rights."

The following table sets forth the dollar range of equity securities beneficially owned by each trustee as of December 31, 2002:

No trustee who is not an interested person of the Fund owns beneficially or of record, any security of Nuveen Advisory, Nuveen, Citigroup Global Markets Inc. or any person (other than a registered investment company) directly or indirectly controlling, controlled by or under common control with Nuveen Advisory, Nuveen or Citigroup Global Markets Inc.

The following table sets forth estimated compensation to be paid by the Fund projected during the Fund's first full fiscal year after commencement of operation. The Fund does not have a retirement or pension plan. The officers and trustees affiliated with Nuveen serve without any compensation from the Fund. The Fund has a deferred compensation plan (the "Plan") that permits any trustee who is not an "interested person" of the Fund to elect to defer receipt of all or a portion of his or her compensation as a trustee. The deferred compensation of a participating trustee is credited to a book reserve account of the Trust when the compensation would otherwise have been paid to the trustee. The value of the trustee's deferral account at any time is equal to the value that the account would have had if contributions to the account had been invested and reinvested in shares of one or more of the eligible Nuveen funds. At the time for commencing distributions from a trustee's deferral account, the trustee may elect to receive distributions in a lump sum or over a period of five years. The Fund will not be liable for any other fund's obligations to make distributions under the Plan.

* Includes net assets attributable to MuniPreferred shares.

In addition to the fee of Nuveen Advisory, the Fund pays all other costs and expenses of its operations, including compensation of its trustees (other than those affiliated with Nuveen Advisory), custodian, transfer agency and dividend disbursing expenses, legal fees, expenses of independent auditors, expenses of repurchasing shares, expenses of issuing MuniPreferred shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies and taxes, if any. All fees and expenses are accrued daily and deducted before payment of dividends to investors.

For the first eight full years of the Fund's operation, Nuveen Advisory has contractually agreed to reimburse the Fund for fees and expenses in the amounts, and for the time periods, set forth below:

S-26

Reducing Fund expenses in this manner will tend to increase the amount of income available for the common and MuniPreferred shareholders. Nuveen Advisory has not agreed to reimburse the Fund for any portion of its fees and expenses beyond November 30, 2011.

Unless earlier terminated as described below, the Fund's investment management agreement with Nuveen Advisory (the "management agreement") will remain in effect until August 1, 2005. The management agreement continues in effect from year to year so long as such continuation is approved at least annually by (1) the Board of Trustees or the vote of a majority of the outstanding voting securities of the Fund, and (2) a majority of the trustees who are not interested persons of any party to the investment management agreement, cast in person at a meeting called for the purpose of voting on such approval. The investment management agreement may be terminated at any time, without penalty, by either the Fund or Nuveen Advisory upon 60 days written notice, and is automatically terminated in the event of its assignment as defined in the 1940 Act.

The management agreement has been approved by a majority of the independent trustees of the Fund and the sole shareholder of the Fund. The independent trustees have determined that the terms of the Fund's management agreement are fair and reasonable and that the agreement is in the Fund's best interests. The independent trustees believe that the management agreement will enable the Fund to obtain high quality investment management services at a cost that they deem appropriate, reasonable, and in the best interests of the Fund and its shareholders. In making such determination, the independent trustees met independently from the interested trustee of the Fund and any officers of Nuveen Advisory and its affiliates. The independent trustees also relied upon the assistance of counsel to the independent trustees.

In evaluating the investment management agreement, the independent trustees reviewed materials furnished by Nuveen Advisory at the annual contract renewal meeting held in May 2003, including information regarding Nuveen Advisory, its affiliates and its personnel, operations and financial condition. The independent trustees discussed with representatives of Nuveen Advisory the Fund's operations and Nuveen Advisory's ability to provide advisory and other services to the Fund. The independent trustees also reviewed, among other things, the nature and quality of services to be provided by Nuveen Advisory, the proposed fees to be charged by Nuveen Advisory for investment management services, the profitability to Nuveen Advisory of its relationship with the Fund, fall-out benefits to Nuveen Advisory from that relationship, economies of scale achieved by Nuveen Advisory, the experience of the investment advisory and other personnel providing services to the Fund, the historical quality of the services provided by Nuveen Advisory and comparative fees and expense ratios of investment companies with similar objectives and strategies managed by other investment advisers, and other factors that the independent trustees deemed relevant.

The Fund, Nuveen Advisory, Nuveen and other related entities have adopted codes of ethics which essentially prohibit certain of their personnel, including the Nuveen fund portfolio manager, from engaging in personal investments which compete or interfere with, or attempt to take advantage of a client's, including the Fund's, anticipated or actual portfolio transactions, and are designed to assure that the interests of clients, including Fund shareholders, are placed before the interests of personnel in connection with personal investment transactions. Text-only versions of the codes of ethics of the Fund, Nuveen Advisory and Nuveen can be viewed online or downloaded from the EDGAR Database on the SEC's internet web site at www.sec.gov. You may also review and copy those documents by visiting the SEC's Public Reference Room in Washington, DC. Information on the operation of the Public Reference Room may be obtained by calling the SEC at 202-942-8090. In addition, copies of the codes of ethics may be obtained, after mailing the appropriate duplicating fee, by writing to the SEC's Public Reference Section, 450 5th Street, N.W., Washington, DC 20549-0102 or by e-mail request at publicinfo@sec.gov.

S-27

PROXY VOTING POLICIES

The Fund invests primarily in municipal securities. On rare occasions the Fund may acquire, directly or through a special purpose vehicle, equity securities of a municipal bond issuer whose bonds the Fund already owns when such bonds have deteriorated or are expected shortly to deteriorate significantly in credit quality. The purpose of acquiring equity securities generally will be to acquire control of the municipal bond issuer and to seek to prevent the credit deterioration or facilitate the liquidation or other workout of the distressed issuer's credit problem. In the course of exercising control of a distressed municipal issuer, Nuveen Advisory may pursue the Fund's interests in a variety of ways, which may entail negotiating and executing consents, agreements and other arrangements, and otherwise influencing the management of the issuer. Nuveen Advisory does not consider such activities proxy voting for purposes of Rule 206(4)-6 under the Investment Advisers Act of 1940, but nevertheless provides reports to the Fund's Board of Trustees on its control activities on a quarterly basis.

In the rare event that a municipal issuer held by the Fund were to issue a proxy, or that the Fund were to receive a proxy issued by a cash management security, Nuveen Advisory would either engage an independent third party to determine how the proxy should be voted or vote the proxy with the consent, or based on the instructions, of the Fund's Board of Trustees or its representative. In the case of a conflict of interest, the proxy would be submitted to the Fund's Board to determine how the proxy should be voted. A member of Nuveen Advisory's legal department would oversee the administration of the voting, and ensure that records were maintained in accordance with Rule 206(4)-6, reports were filed with the Securities and Exchange Commission ("SEC") on Form N-PX, and the results provided to the Fund's Board of Trustees and made available to shareholders as required by applicable rules.

PORTFOLIO TRANSACTIONS

Nuveen Advisory is responsible for decisions to buy and sell securities for the Fund and for the placement of the Fund's securities business, the negotiation of the prices to be paid for principal trades and the allocation of its transactions among various dealer firms. Portfolio securities will normally be purchased directly from an underwriter or in the over-the-counter market from the principal dealers in such securities, unless it appears that a better price or execution may be obtained through other means. Portfolio securities will not be purchased from Nuveen or its affiliates except in compliance with the 1940 Act.

The Fund expects that substantially all portfolio transactions will be effected on a principal (as opposed to an agency) basis and, accordingly, does not expect to pay any brokerage commissions. Purchases from underwriters will include a commission or concession paid by the issuer to the underwriter, and purchases from dealers will include the spread between the bid and asked price. On occasion, the Fund may clear portfolio transactions through Nuveen. It is the policy of Nuveen Advisory to seek the best execution under the circumstances of each trade. Nuveen Advisory evaluates price as the primary consideration, with the financial condition, reputation and responsiveness of the dealer considered secondary in determining best execution. Given the best execution obtainable, it will be Nuveen Advisory's practice to select dealers which, in addition, furnish research information (primarily credit analyses of issuers and general economic reports) and statistical and other services to Nuveen Advisory. It is not possible to place a dollar value on information and statistical and other services received from dealers. Since it is only supplementary to Nuveen Advisory's own research efforts, the receipt of research information is not expected to reduce significantly Nuveen Advisory's expenses. While Nuveen Advisory will be primarily responsible for the placement of the business of the Fund, the policies and practices of Nuveen Advisory in this regard must be consistent with the foregoing and will, at all times, be subject to review by the Board of Trustees of the Fund.

S-28

Nuveen Advisory may manage other investment accounts and investment companies for other clients which have investment objectives similar to those of the Fund. Subject to applicable laws and regulations, Nuveen Advisory seeks to allocate portfolio transactions equitably whenever concurrent decisions are made to purchase or sell securities by the Fund and another advisory account. In making such allocations the main factors to be considered will be the respective investment objectives, the relative size of portfolio holdings of the same or comparable securities, the availability of cash for investment and the size of investment commitments generally held. While this procedure could have a detrimental effect on the price or amount of the securities available to the Fund from time to time, it is the opinion of the Board of Trustees that the benefits available from Nuveen Advisory's organization will outweigh any disadvantage that may arise from exposure to simultaneous transactions.

NET ASSET VALUE

The Fund's net asset value per share is determined as of the close of regular session trading (normally 4:00 p.m. eastern time) on each day the New York Stock Exchange is open for business. Net asset value is calculated by taking the fair value of the Fund's total assets, including interest or dividends accrued but not yet collected, less all liabilities, and dividing by the total number of shares outstanding. The result, rounded to the nearest cent, is the net asset value per share

In determining net asset value, expenses are accrued and applied daily and securities and other assets for which market quotations are available are valued at market value. The prices of municipal bonds are provided by a pricing service and based on the mean between the bid and asked price. When price quotes are not readily available (which is usually the case for municipal bonds), the pricing service establishes a fair market value based on prices of comparable municipal bonds. All valuations are subject to review by the Fund's Board of Trustees or its delegate, Nuveen Advisory.

ADDITIONAL INFORMATION CONCERNING THE AUCTIONS FOR MUNIPREFERRED

GENERAL

Auction Agency Agreement. The Fund has entered into an Auction Agency Agreement (the "Auction Agency Agreement") with the Auction Agent (currently, Deutsche Bank Trust Company Americas) which provides, among other things, that the Auction Agent will follow the Auction Procedures for purposes of determining the Applicable Rate for shares of each series of MuniPreferred so long as the Applicable Rate for shares of such series is to be based on the results of an Auction.

Broker-Dealer Agreements. Each Auction requires the participation of one or more Broker-Dealers. The Auction Agent has entered into agreements (collectively, the "Broker-Dealer Agreements") with several Broker-Dealers selected by the Fund, which provide for the participation of those Broker-Dealers in Auctions for shares of MuniPreferred. See "Broker-Dealers" below.

Securities Depository. The Depository Trust Company ("DTC") will act as the Securities Depository for the Agent Members (as defined below) with respect to shares of each series of MuniPreferred. One certificate for all of the shares of each series of MuniPreferred will be registered in the name of Cede & Co., as nominee of the Securities Depository. Such certificate will bear a legend to the effect that such certificate is issued subject to the provisions restricting transfers of shares of MuniPreferred contained in the Statement. The Fund will also issue stop-transfer instructions to the transfer agent for shares of each series of MuniPreferred. Prior to the commencement of the right of holders of preferred shares to elect a majority of the Fund's trustees, as described under "Description of MuniPreferred Shares--Voting Rights" in the Prospectus, Cede & Co. will be the holder of record of all

S-29

shares of each series of MuniPreferred and owners of such shares will not be entitled to receive certificates representing their ownership interest in such shares.

DTC, a New York-chartered limited purpose trust company, performs services for its participants (including the Agent Members), some of whom (and/or their representatives) own DTC. DTC maintains lists of its participants and will maintain the positions (ownership interests) held by each such participant (the "Agent Member") in shares of MuniPreferred, whether for its own account or as a nominee for another person.

CONCERNING THE AUCTION AGENT

The Auction Agent is acting as agent for the Fund in connection with Auctions. In the absence of bad faith or negligence on its part, the Auction Agent will not be liable for any action taken, suffered, or omitted or for any error of judgment made by it in the performance of its duties under the Auction Agency Agreement and will not be liable for any error of judgment made in good faith unless the Auction Agent will have been negligent in ascertaining the pertinent facts.

The Auction Agent may rely upon, as evidence of the identities of the Existing Holders of shares of MuniPreferred, the Auction Agent's registry of Existing Holders, the results of Auctions and notices from any Broker-Dealer (or other Person, if permitted by the Fund) with respect to transfers described under "The Auction--Secondary Market Trading and Transfer of MuniPreferred" in the Prospectus and notices from the Fund. The Auction Agent is not required to accept any such notice for an Auction unless it is received by the Auction Agent by 3:00 p.m., New York City time, on the Business Day preceding such Auction.

The Auction Agent may terminate the Auction Agency Agreement upon notice to the Fund on a date no earlier than 45 days after such notice. If the Auction Agent should resign, the Fund will use its best efforts to enter into an agreement with a successor Auction Agent containing substantially the same terms and conditions as the Auction Agency Agreement. The Fund may remove the Auction Agent provided that prior to such removal the Fund shall have entered into such an agreement with a successor Auction Agent.

BROKER-DEALERS

The Auction Agent after each Auction for shares of MuniPreferred will pay to each Broker-Dealer, from funds provided by the Fund, a service charge at the annual rate of 1/4 of 1% in the case of any Auction immediately preceding a Rate Period of less than 364 Rate Period Days, or a percentage agreed to by the Fund and the Broker-Dealers in the case of any Auction immediately preceding a Rate Period of 364 Rate Period Days or longer, of the purchase price of shares of MuniPreferred placed by such Broker-Dealer at such Auction. For the purposes of the preceding sentence, shares of MuniPreferred will be placed by a Broker-Dealer if such shares were (a) the subject of Hold Orders deemed to have been submitted to the Auction Agent by the Broker-Dealer and were acquired by such Broker-Dealer for its own account or were acquired by such Broker-Dealer for its customers who are Beneficial Owners or (b) the subject of an Order submitted by such Broker-Dealer that is (i) a Submitted Bid of an Existing Holder that resulted in such Existing Holder continuing to hold such shares as a result of the Auction or (ii) a Submitted Bid of a Potential Holder that resulted in such Potential Holder purchasing such shares as a result of the Auction or (iii) a valid Hold Order.

The Fund may request the Auction Agent to terminate one or more Broker-Dealer Agreements at any time, provided that at least one Broker-Dealer Agreement is in effect after such termination.

S-30

The Broker-Dealer Agreement provides that a Broker-Dealer (other than an affiliate of the Fund) may submit Orders in Auctions for its own account, unless the Fund notifies all Broker-Dealers that they may no longer do so, in which case Broker-Dealers may continue to submit Hold Orders and Sell Orders for their own accounts. Any Broker-Dealer that is an affiliate of the Fund may submit Orders in Auctions, but only if such Orders are not for its own account. If a Broker-Dealer submits an Order for its own account in any Auction, it might have an advantage over other Bidders because it would have knowledge of all Orders submitted by it in that Auction; such Broker-Dealer, however, would not have knowledge of Orders submitted by other Broker-Dealers in that Auction.

DESCRIPTION OF COMMON SHARES

In addition to the MuniPreferred shares, the Declaration authorizes the issuance of an unlimited number of common shares, par value of $0.01 per share. All outstanding common shares have equal rights to the payment of dividends and the distribution of assets upon liquidation, are fully paid and, subject to matters discussed in "Certain Provisions in the Declaration of Trust," non-assessable, and have no pre-emptive or conversion rights or rights to cumulative voting. Whenever MuniPreferred shares are outstanding, holders of the Fund's common shares will not be entitled to receive any cash distributions from the Fund unless all accrued dividends on MuniPreferred shares have been paid, and unless asset coverage (as defined in the 1940 Act) with respect to MuniPreferred shares would be at least 200% after giving effect to the distributions.

CERTAIN PROVISIONS IN THE DECLARATION OF TRUST

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Fund. However, the Declaration contains an express disclaimer of shareholder liability for debts or obligations of the Fund and requires that notice of such limited liability be given in each agreement, obligation or instrument entered into or executed by the Fund or the trustees. The Declaration further provides for indemnification out of the assets and property of the Fund for all loss and expense of any shareholder held personally liable for the obligations of the Fund. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which the Fund would be unable to meet its obligations. The Fund believes that the likelihood of such circumstances is remote.

The Declaration includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. Specifically, the Declaration requires a vote by holders of at least two-thirds of the common shares and MuniPreferred shares, voting together as a single class, except as described below, to authorize (1) a conversion of the Fund from a closed-end to an open-end investment company, (2) a merger or consolidation of the Fund, or a series or class of the Fund, with any corporation, association, trust or other organization or a reorganization of the Fund, or a series or class of the Fund, (3) a sale, lease or transfer of all or substantially all of the Fund's assets (other than in the regular course of the Fund's investment activities), (4) in certain circumstances, a termination of the Fund, or a series or class of the Fund or (5) removal of trustees by shareholders, and then only for cause, unless, with respect to (1) through (4), such transaction has already been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-laws, in which case the affirmative vote of the holders of at least a majority of the Fund's common shares and MuniPreferred shares outstanding at the time, voting together as a single class, is required, provided, however, that where only a particular class or series is affected (or, in the case of removing a trustee, when the trustee has been elected by only one class), the required vote only by the applicable class or series will be required. Approval of shareholders is not required, however, for any transaction, whether deemed a merger, consolidation, reorganization or otherwise whereby the Fund

S-31

issues shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity. In the case of the conversion of the Fund to an open-end investment company, or in the case of any of the foregoing transactions constituting a plan of reorganization which adversely affects the holders of MuniPreferred shares, the action in question will also require the affirmative vote of the holders of at least two-thirds of the Fund's MuniPreferred shares outstanding at the time, voting as a separate class, or, if such action has been authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or the By-laws, the affirmative vote of the holders of at least a majority of the Fund's MuniPreferred shares outstanding at the time, voting as a separate class. None of the foregoing provisions may be amended except by the vote of at least two-thirds of the common shares and MuniPreferred shares, voting together as a single class. The votes required to approve the conversion of the Fund from a closed-end to an open-end investment company or to approve transactions constituting a plan of reorganization which adversely affects the holders of MuniPreferred shares are higher than those required by the 1940 Act. The Board of Trustees believes that the provisions of the Declaration relating to such higher votes are in the best interest of the Fund and its shareholders.

Reference should be made to the Declaration on file with the Securities and Exchange Commission for the full text of these provisions.

The Declaration provides that the obligations of the Fund are not binding upon the trustees of the Fund individually, but only upon the assets and property of the Fund, and that the trustees shall not be liable for errors of judgment or mistakes of fact or law. Nothing in the Declaration, however, protects a trustee against any liability to which he would otherwise be subject by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office.

REPURCHASE OF FUND SHARES; CONVERSION TO OPEN-END FUND

The Fund is a closed-end investment company and as such its shareholders will not have the right to cause the Fund to redeem their shares. Instead, the Fund's common shares will trade in the open market at a price that will be a function of several factors, including dividend levels (which are in turn affected by expenses), net asset value, call protection, price, dividend stability, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Because shares of a closed-end investment company may frequently trade at prices lower than net asset value, the Fund's Board of Trustees has currently determined that, at least annually, it will consider action that might be taken to reduce or eliminate any material discount from net asset value in respect of common shares, which may include the repurchase of such shares in the open market or in private transactions, the making of a tender offer for such shares at net asset value, or the conversion of the Fund to an open-end investment company. There can be no assurance, however, that the Board of Trustees will decide to take any of these actions, or that share repurchases or tender offers, if undertaken, will reduce market discount.

Notwithstanding the foregoing, at any time when the Fund's MuniPreferred shares are outstanding, the Fund may not purchase, redeem or otherwise acquire any of its common shares unless (1) all accrued MuniPreferred shares dividends have been paid and (2) at the time of such purchase, redemption or acquisition, the net asset value of the Fund's portfolio (determined after deducting the acquisition price of the common shares) is at least 200% of the liquidation value of the outstanding MuniPreferred shares (expected to equal the original purchase price per share plus any accrued and unpaid dividends thereon). The staff of the Securities and Exchange Commission currently requires that any tender offer made by a closed-end investment company for its shares must be at a price equal to the net asset value of such shares at the close of business on the last day of the tender offer. Any service fees incurred in connection with any tender offer made by the Fund will be borne by the Fund and will not reduce the stated consideration to be paid to tendering shareholders.

S-32

Subject to its investment limitations, the Fund may borrow to finance the repurchase of shares or to make a tender offer. Interest on any borrowings to finance share repurchase transactions or the accumulation of cash by the Fund in anticipation of share repurchases or tenders will reduce the Fund's net income. Any share repurchase, tender offer or borrowing that might be approved by the Board of Trustees would have to comply with the Securities Exchange Act of 1934, as amended, and the 1940 Act and the rules and regulations thereunder.

Although the decision to take action in response to a discount from net asset value will be made by the Board of the Fund at the time it considers such issue, it is the Board's present policy, which may be changed by the Board, not to authorize repurchases of common shares or a tender offer for such shares if
(1) such transactions, if consummated, would (a) result in the delisting of the common shares from the American Stock Exchange, or (b) impair the Fund's status as a regulated investment company under the Internal Revenue Code of 1986, as amended (which would make the Fund a taxable entity, causing the Fund's income to be taxed at the corporate level in addition to the taxation of shareholders who receive dividends from the Fund) or as a registered closed-end investment company under the 1940 Act; (2) the Fund would not be able to liquidate portfolio securities in an orderly manner and consistent with the Fund's investment objectives and policies in order to repurchase shares; or (3) there is, in the Board's judgment, any (a) material legal action or proceeding instituted or threatened challenging such transactions or otherwise materially adversely affecting the Fund, (b) general suspension of or limitation on prices for trading securities on the American Stock Exchange, (c) declaration of a banking moratorium by Federal or state authorities or any suspension of payment by United States or state banks in which the Fund invests, (d) material limitation affecting the Fund or the issuers of its portfolio securities by federal or state authorities on the extension of credit by lending institutions or on the exchange of foreign currency, (e) commencement of war, armed hostilities or other international or national calamity directly or indirectly involving the United States, or (f) other event or condition which would have a material adverse effect (including any adverse tax effect) on the Fund or its shareholders if shares were repurchased. The Board of Trustees of the Fund may in the future modify these conditions in light of experience.

Conversion to an open-end company would require the approval of the holders of at least two-thirds of the Fund's common shares and MuniPreferred shares outstanding at the time, voting together as a single class, and of the holders of at least two-thirds of the Fund's MuniPreferred shares outstanding at the time, voting as a separate class, provided however, that such separate class vote shall be a majority vote if the action in question has previously been approved, adopted or authorized by the affirmative vote of two-thirds of the total number of trustees fixed in accordance with the Declaration or By-laws. See the prospectus under "Certain Provisions in the Declaration of Trust" for a discussion of voting requirements applicable to conversion of the Fund to an open-end company. If the Fund converted to an open-end company, it would be required to redeem all MuniPreferred shares then outstanding, and the Fund's common shares would no longer be listed on the American Stock Exchange. Shareholders of an open-end investment company may require the company to redeem their shares on any business day (except in certain circumstances as authorized by or under the 1940 Act) at their net asset value, less such redemption charge, if any, as might be in effect at the time of redemption. In order to avoid maintaining large cash positions or liquidating favorable investments to meet redemptions, open-end companies typically engage in a continuous offering of their shares. Open-end companies are thus subject to periodic asset in-flows and out-flows that can complicate portfolio management. The Board of Trustees of the Fund may at any time propose conversion of the Fund to an open-end company depending upon their judgment as to the advisability of such action in light of circumstances then prevailing.

The repurchase by the Fund of its shares at prices below net asset value would result in an increase in the net asset value of those shares that remain outstanding. However, there can be no assurance that share repurchases or tenders at or below net asset value would result in the Fund's shares

S-33

trading at a price equal to their net asset value. Nevertheless, the fact that the Fund's shares may be the subject of repurchase or tender offers at net asset value from time to time, or that the Fund may be converted to an open-end company, may reduce any spread between market price and net asset value that might otherwise exist.

In addition, a purchase by the Fund of its common shares would decrease the Fund's total assets which would likely have the effect of increasing the Fund's expense ratio. Any purchase by the Fund of its common shares at a time when MuniPreferred shares are outstanding will increase the leverage applicable to the outstanding common shares then remaining.

Before deciding whether to take any action if the Fund's common shares trade below net asset value, the Board of the Fund would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund's portfolio, the impact of any action that might be taken on the Fund or its shareholders and market considerations. Based on these considerations, even if the Fund's shares should trade at a discount, the Board of Trustees may determine that, in the interest of the Fund and its shareholders, no action should be taken.

FEDERAL INCOME TAX MATTERS

The following is intended to be a general summary of certain US federal income tax consequences of investing in shares of MuniPreferred. It is not intended to be a complete discussion of all such federal income tax consequences, nor does it purport to deal with all categories of investors. Investors are advised to consult with their own tax advisors before investing in the Fund.

The Fund intends to elect to be treated, and to qualify each year, as a regulated investment company, under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and to satisfy conditions which enable dividends on common shares and shares of MuniPreferred which are attributable to interest on municipal obligations to be exempt from federal income tax in the hands of owners of such stock, subject to the possible application of the federal alternative minimum tax.

To qualify under Subchapter M of the Code as a regulated investment company, the Fund must, among other things: (a) distribute to its shareholders each year at least 90% of the sum of (i) its investment company taxable income (as that term is defined in the Code, determined without regard to the deduction for dividends paid) and (ii) its net tax-exempt income (the excess of its gross tax-exempt interest income over certain disallowed deductions) and (b) diversify its holdings so that, at the end of each quarter of the Fund's taxable year (i) at least 50% of the market value of the Fund's assets is represented by cash, cash items, U.S. government securities, securities of other regulated investment companies, and other securities, with these other securities limited, with respect to any one issuer, to an amount not greater in value than 5% of the Fund's total assets, and to not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the market value of the Fund's assets is invested in the securities of any one issuer (other than U.S. government securities or securities of other regulated investment companies) or two or more issuers controlled by the Fund and engaged in the same, similar or related trades or businesses. In meeting these requirements, the Fund may be restricted in the utilization of certain of the investment techniques described under "Investment Policies and Techniques" and "Other Investment Policies and Techniques" above. If for any taxable year the Fund did not qualify as a regulated investment company for federal income tax purposes, it would be treated as a corporation subject to federal income tax and distributions to its shareholders would not be deducted by the Fund in computing its taxable income. In addition, in the event of a failure to qualify as a regulated investment company, the Fund's distributions, to the extent derived from the Fund's current or accumulated earnings and profits, would generally constitute ordinary dividends, which generally would

S-34

be eligible for the dividends received deduction available to corporate shareholders and the reduced rate of taxation for "qualified dividend income" available to noncorporate shareholders.

A regulated investment company that fails to distribute, by the close of each calendar year, an amount equal to the sum of 98% of its ordinary taxable income for such year and 98% of its capital gain net income for the one-year period ending October 31 in such year, plus any shortfalls from the prior years' required distribution, is liable for a nondeductible 4% federal excise tax on the excess of the required distribution for such calendar year over the distributed amount for such calendar year. To avoid the imposition of this excise tax, the Fund generally intends to make the required distributions of its ordinary taxable income, if any, and its capital gain net income, to the extent possible, by the close of each calendar year.

The Fund intends to qualify to pay "exempt-interest" dividends, as defined in the Code, on its common shares and shares of MuniPreferred by satisfying the requirement that, at the close of each quarter of its taxable year, at least 50% of the value of its total assets consist of tax-exempt municipal bonds. Exempt-interest dividends are dividends or any part thereof (other than a capital gain dividend) paid by the Fund which are attributable to interest on municipal bonds and are so designated by the Fund. Exempt-interest dividends will be exempt from federal income tax, subject to the possible application of the federal alternative minimum tax. Insurance proceeds received by the Fund under any insurance policies in respect of scheduled interest payments on defaulted municipal bonds, as described herein, will generally be excludable from federal gross income under Section 103(a) of the Code. In the case of non-appropriation by a political subdivision, however, there can be no assurance that payments made by the issuer representing interest on such "non-appropriation" municipal lease obligations will be excludable from gross income for federal income tax purposes. See "Investment Policies and Techniques" above. Gains of the Fund that are attributable to market discount on certain municipal obligations are treated as ordinary income to the extent of accrued market discount on the bond.

Distributions to shareholders of net investment income received by the Fund from taxable temporary investments, if any, and of net short-term capital gains realized by the Fund, if any, will be taxable to its shareholders as ordinary income. Distributions by the Fund of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss), if any, are taxable as long-term capital gain, regardless of the length of time the shareholder has owned the shares with respect to which such distributions are made. The amount of taxable income allocable to the Fund's shares will depend upon the amount of such income realized by the Fund, but is not generally expected to be significant. Except for dividends paid on shares of MuniPreferred which include an allocable portion of any net capital gain or other taxable income, the Fund anticipates that all other dividends paid on shares of its MuniPreferred will constitute exempt-interest dividends for federal income tax purposes. Distributions, if any, in excess of the Fund's earnings and profits will first reduce the adjusted tax basis of a shareholder's shares and, after that basis has been reduced to zero, will constitute capital gain to the shareholder (assuming the shares are held as a capital asset). As long as the Fund qualifies as a regulated investment company under the Code, no part of its distributions to shareholders will qualify for the dividends-received deduction available to corporate shareholders or as "qualified dividend income" available to noncorporate shareholders.

The Internal Revenue Service (the "IRS") requires that a regulated investment company that has two or more classes of shares must designate to each such class proportionate amounts of each type of its income for each tax year based upon the percentage of total dividends distributed to each class for such year. The Fund intends each year to allocate, to the fullest extent practicable, net tax-exempt interest, net capital gain and other taxable income, if any, between its common shares and shares of MuniPreferred in proportion to the total dividends paid to each class with respect to such year. To the extent permitted under applicable law, the Fund reserves the right to make special allocations of income within a class,

S-35

consistent with the objectives of the Fund. The Fund will, in the case of a Minimum Rate Period or a Special Rate Period of 28 Rate Period Days or fewer, and may, in the case of any other Special Rate Period, notify the Auction Agent of the amount of any net capital gain or other income taxable for regular federal income tax purposes to be included in any dividend on shares of its MuniPreferred prior to the Auction establishing the Applicable Rate for such dividend. If (a) in the case of any Minimum Rate Period or any Special Rate Period of 28 Rate Period Days or fewer, the Fund allocates any net capital gain or other income taxable for regular federal income tax purposes to a dividend paid on shares of MuniPreferred without having given advance notice thereof to the Auction Agent as required by the Statement solely by reason of the fact that such allocation is made retroactively as a result of the redemption of all or a portion of the outstanding shares of its MuniPreferred or the liquidation of the Fund or (b) in the case of any Special Rate Period of more than 28 Rate Period Days, the Fund allocates any net capital gain or other taxable income for regular federal income tax purposes to shares of its MuniPreferred without having given advance notice thereof as described above, the Fund will make certain payments to owners of shares of its MuniPreferred to which such allocation was made to offset the federal income tax effect thereof as described under "Description of MuniPreferred Shares--Dividends and Dividend Periods--Gross-up Payments" in the Prospectus.

In order for any distributions to owners of the shares of MuniPreferred to be eligible to be treated as exempt-interest dividends, such shares of MuniPreferred must be treated as stock for federal income tax purposes. Nuveen Advisory believes the shares of MuniPreferred should be treated as stock for federal income tax purposes.

If at any time when the Fund's shares of MuniPreferred are outstanding the Fund fails to meet the MuniPreferred Basic Maintenance Amount or the 1940 Act MuniPreferred Asset Coverage, the Fund will be required to suspend distributions to holders of its common shares until such maintenance amount or asset coverage, as the case may be, is restored. See "Description of MuniPreferred Shares--Dividends and Dividend Periods--Restrictions on Dividends and Other Distributions" in the Prospectus. This may prevent the Fund from distributing at least 90% of the sum of its investment company taxable income (as that term is defined in the Code, determined without regard to the deduction for dividends paid) and its net tax-exempt income, and may therefore jeopardize the Fund's qualification for taxation as a regulated investment company or cause the Fund to incur an income tax liability or a non-deductible 4% federal excise tax on the undistributed taxable income (including gain), or both. Upon failure to meet the MuniPreferred Basic Maintenance Amount or the 1940 Act MuniPreferred Asset Coverage, the Fund will be required to redeem its shares of MuniPreferred in order to maintain or restore such maintenance amount or asset coverage and avoid the adverse consequences to the Fund and its shareholders of failing to qualify as a regulated investment company. There can be no assurance, however, that any such redemption would achieve such objectives.

The Code provides that interest on indebtedness incurred or continued to purchase or carry the Fund's shares to which exempt-interest dividends are allocated is not deductible. Under rules used by the IRS for determining when borrowed funds are considered used for the purpose of purchasing or carrying particular assets, the purchase or ownership of shares may be considered to have been made with borrowed funds even though such funds are not directly used for the purchase or ownership of such shares.

The interest on private activity bonds in most instances is not federally tax-exempt to a person who is a "substantial user" of a facility financed by such bonds or a "related person" of such "substantial user." As a result, the Fund may not be an appropriate investment for a shareholder who is considered either a "substantial user" or a "related person" within the meaning of the Code. In general, a "substantial user" of a facility includes a "nonexempt person who regularly uses a part of such facility in his trade or business." "Related persons" are in general defined to include persons among whom there exists a

S-36

relationship, either by family or business, which would result in a disallowance of losses in transactions among them under various provisions of the Code (or if they are members of the same controlled group of corporations under the Code), including a partnership and each of its partners (and certain members of their families), an S corporation and each of its shareholders (and certain members of their families) and various combinations of these and other relationships. The foregoing is not a complete description of all of the provisions of the Code covering the definitions of "substantial user" and "related person."

The Fund may, at its option, redeem shares of its MuniPreferred in whole or in part, and is required to redeem shares of its MuniPreferred to the extent required to maintain the MuniPreferred Basic Maintenance Amount and the 1940 Act MuniPreferred Asset Coverage. Gain or loss, if any, resulting from a redemption of the shares of MuniPreferred will be taxed as gain or loss from the sale or exchange of the shares of MuniPreferred under Section 302 of the Code rather than as a dividend, but only if the redemption distribution (a) is deemed not to be essentially equivalent to a dividend, (b) is in complete redemption of an owner's interest in the Fund, (c) is substantially disproportionate with respect to the owner, or (d) with respect to non-corporate owners, is in partial liquidation of the Fund. In determining whether the above conditions are satisfied, shares owned by certain persons related to the owner will be treated as held by such owner and, for purposes of (a), (b) and (c) above, an owner's ownership of common shares will be taken into account.

Nonresident alien individuals and certain foreign corporations and other entities ("foreign investors") generally are subject to U.S. federal income tax withholding at the rate of 30% (or possibly a lower rate provided by an applicable tax treaty) on distributions of taxable net investment income and net short-term capital gain. To the extent received by foreign investors, exempt-interest dividends, distributions of net long-term capital gain and gain from the sale or other disposition of the shares of MuniPreferred generally are exempt from U.S. federal income taxation. Different tax consequences may result if the owner is engaged in a trade or business in the United States or, in the case of an individual, is present in the United States for more than 182 days during a taxable year and certain other conditions are met.

Although dividends generally will be treated as distributed when paid, dividends declared in October, November or December, payable to shareholders of record on a specified date in one of those months and paid during the following January, will be treated as having been distributed by the Fund (and received by the shareholders) on December 31 of the year declared.

Certain of the Fund's investment practices are subject to special provisions of the Code that, among other things, may defer the use of certain deductions or losses of the Fund, affect the holding period of securities held by the Fund, and alter the character of the gains or losses realized by the Fund. These provisions may also require the Fund to recognize income or gain without receiving cash with which to make distributions in the amounts necessary to satisfy the requirements for maintaining regulated investment company status and for avoiding income and excise taxes. The Fund will monitor its transactions and may make certain tax elections in order to mitigate the effect of these rules and prevent disqualification of the Fund as a regulated investment company.

The sale or other disposition of shares of MuniPreferred (other than redemptions, the rules for which are described above) will normally result in capital gain or loss to shareholders who hold their shares as capital assets. Present law taxes both long-term and short-term capital gains of corporations at the rates applicable to ordinary income. For non-corporate taxpayers, however, long-term capital gains are generally subject to reduced rates of taxation. Losses realized by a shareholder on the sale or exchange of shares of the Fund held for six months or less are disallowed to the extent of any distribution of exempt-interest dividends received with respect to such shares, and, if not disallowed, such losses are treated as long-term capital losses to the extent of any distribution of long-term capital gain received (or

S-37

designated amounts of undistributed capital gain that are treated as received) with respect to such shares. Under certain circumstances, a shareholder's holding period may have to restart after, or may be suspended for, any periods during which the shareholder's risk of loss is diminished as a result of holding one or more other positions in substantially similar or related property, or through certain options or short sales. Any loss realized on a sale or exchange of shares of the Fund will be disallowed to the extent those shares of the Fund are replaced by other substantially identical shares of the Fund within a period of 61 days beginning 30 days before and ending 30 days after the date of disposition of the original shares. In that event, the basis of the replacement shares of the Fund will be adjusted to reflect the disallowed loss.

Federal income tax law imposes an alternative minimum tax with respect to corporations, individuals, trusts and estates. Interest on certain municipal obligations, such as bonds issued to make loans for housing purposes or to private entities (but not to certain tax-exempt organizations such as universities and non-profit hospitals) is included as an item of tax preference in determining the amount of a taxpayer's alternative minimum taxable income. To the extent that the Fund receives income from municipal obligations subject to the federal alternative minimum tax, a portion of the dividends paid by the Fund, although otherwise exempt from federal income tax, will be taxable to its shareholders to the extent that their tax liability is determined under the federal alternative minimum tax. The Fund will annually provide a report indicating the percentage of the Fund's income attributable to municipal obligations subject to the federal alternative minimum tax. In addition, for certain corporations, federal alternative minimum taxable income is increased by 75% of the difference between an alternative measure of income ("adjusted current earnings") and the amount otherwise determined to be the alternative minimum taxable income. Interest on all municipal obligations, and therefore all distributions by the Fund that would otherwise be tax-exempt, is included in calculating a corporation's adjusted current earnings. Certain small corporations are not subject to the federal alternative minimum tax.

Tax-exempt income, including exempt-interest dividends paid by the Fund, is taken into account in calculating the amount of social security and railroad retirement benefits that may be subject to federal income tax.

The Fund is required in certain circumstances to withhold a portion of taxable dividends and certain other payments paid to certain holders of the Fund's shares who do not furnish to the Fund their correct taxpayer identification number (in the case of individuals, their social security number) and certain certifications, or who are otherwise subject to backup withholding. Backup withholding is not an additional tax. Any amounts withheld from payments made to a shareholder may be refunded or credited against such shareholder's federal income tax liability, provided the required information is furnished to the IRS.

The Code provides that every shareholder required to file a tax return must include for information purposes on such return the amount of tax-exempt interest received during the taxable year, including any exempt-interest dividends received from the Fund.

The foregoing is a general summary of certain provisions of the Code and regulations thereunder presently in effect as they directly govern the federal income taxation of the Fund and its shareholders. These provisions are subject to change by legislative or administrative action, and any such change may be retroactive. Moreover, the foregoing does not address many of the factors that may be determinative of whether an investor will be liable for the alternative minimum tax. Shareholders are advised to consult their own tax advisors for more detailed information concerning the federal, foreign, state and local tax consequences of purchasing, holding and disposing of Fund shares.

Note 1: Organization

The Fund was organized as a Massachusetts business trust on October 8, 2003, and has been inactive since that date except for matters relating to its organization and registration as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended, and the Securities Act of 1933, as amended, and the sale of 7,000 Common Shares to Nuveen Advisory Corp., the Fund's investment adviser (the "Adviser"), a wholly owned subsidiary of Nuveen Investments, Inc.

Nuveen Investments, LLC, also a wholly owned subsidiary of Nuveen Investments, Inc., has agreed to reimburse all organization expenses (approximately $11,500) and pay all Common Share offering costs (other than the sales load) that exceed $.03 per Common Share.

The Fund seeks to provide high current income exempt from regular federal income tax. The Fund's secondary investment objective is to seek attractive total return consistent with its primary objective.

The Fund is authorized by its Declaration of Trust to issue Preferred Shares ("MuniPreferred Shares") having a liquidation value of $25,000 per share in one or more classes or series, with dividend, liquidation preference and other rights as determined by the Fund's Board of Trustees without approval of the Common Shareholders.

Note 2: Significant Accounting Policies

The Fund's financial statements are prepared in accordance with accounting principles generally accepted in the United States which require the use of management estimates. Actual results may differ from those estimates.

The Fund's share of Common Share offering costs will be recorded as a reduction of the proceeds from the sale of Common Shares upon the commencement of Fund operations.

If the Fund offers MuniPreferred Shares, the offering costs will be borne by Common Shareholders as a direct reduction to paid-in surplus.

Note 3: Investment Management Agreement

Pursuant to an investment management agreement between the Adviser and the Fund, the Fund, upon commencement of Fund operations, has agreed to pay a management fee, payable on a monthly basis, at an annual rate ranging from .7500% of the first $125 million of the average daily net assets (including net assets attributable to MuniPreferred Shares ("Management Assets")) to .6750% of the average daily Managed Assets in excess of $2 billion.

In addition to the reimbursement and waiver of organization and Common Share offering costs discussed in Note 1, the Adviser has contractually agreed to reimburse the Fund for fees and expenses in the amount of .32% of average daily Managed Assets for the first five full years of the Fund's operations, .24% in year 6, .16% in year 7 and .08% in year 8. The Adviser has not agreed to reimburse the Fund for any portion of its fees and expenses beyond November 30, 2011.

Note 4: Income Taxes

The Fund intends to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net investment income, in addition to any significant amounts of net realized capital gains and/or market discount realized from investment transactions, if any.

NOTES TO FINANCIAL STATEMENTS
(Unaudited)

1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES The Fund covered in this report and its corresponding Common share American Stock Exchange symbol is Nuveen Municipal High Income Opportunity Fund (NMZ) (the "Fund"). The Fund is registered under the Investment Company Act of 1940 as a diversified, closed-end management investment company.

Prior to the commencement of operations, the Fund had no operations other than those related to organizational matters, the initial capital contribution of $100,275 by Nuveen Advisory Corp. (the "Adviser"), a wholly owned subsidiary of Nuveen Investments, Inc., and the recording of the organization expenses ($11,500) and their reimbursement by Nuveen Investments, LLC, also a wholly owned subsidiary of Nuveen Investments, Inc.

The Fund seeks to provide high current income exempt from regular federal income tax. The Fund's secondary investment objective is to seek attractive total return consistent with its primary objective. The Fund seeks to achieve its investment objectives by investing primarily in a portfolio of municipal obligations issued by state and local government authorities that the Adviser believes are underrated or undervalued.

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements in accordance with accounting principles generally accepted in the United States.

Securities Valuation
The prices of municipal bonds in the Fund's investment portfolio are provided by a pricing service approved by the Fund's Board of Trustees. When price quotes are not readily available (which is usually the case for municipal securities), the pricing service establishes fair market value based on yields or prices of municipal bonds of comparable quality, type of issue, coupon, maturity and rating, indications of value from securities dealers, evaluations of anticipated cash flows or collateral and general market conditions. If it is determined that market prices for a security are unavailable or inappropriate, the Board of Trustees of the Fund, or its designee, may establish a fair value for the security. Temporary investments in securities that have variable rate and demand features qualifying them as short-term securities are valued at amortized cost, which approximates market value.

Securities Transactions
Securities transactions are recorded on a trade date basis. Realized gains and losses from such transactions are determined on the specific identification method. Securities purchased or sold on a when-issued or delayed delivery basis may have extended settlement periods. The securities so purchased are subject to market fluctuation during this period. The Fund has instructed the custodian to segregate assets with a current value at least equal to the amount of the when-issued and delayed delivery purchase commitments. At December 29, 2003, the Fund had outstanding when-issued and delayed delivery purchase commitments of $17,470,808.

Investment Income
Interest income, which includes the amortization of premiums and accretion of discounts for financial reporting purposes, is recorded on an accrual basis.

Income Taxes
The Fund intends to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net investment income to its shareholders. Therefore, no federal income tax provision is required. Furthermore, the Fund intends to satisfy conditions which will enable interest from municipal securities, which is exempt from regular federal income tax, to retain such tax-exempt status when distributed to shareholders of the Fund.

Dividends and Distributions to Common Shareholders Dividends from tax-exempt net investment income are declared monthly. Net realized capital gains and/or market discount from investment transactions, if any, are distributed to shareholders not less frequently than annually. Furthermore, capital gains are distributed only to the extent they exceed available capital loss carryforwards.

Distributions to Common shareholders of tax-exempt net investment income, net realized capital gains and/or market discount, if any, are recorded on the ex-dividend date. The amount and timing of distributions are determined in accordance with federal income tax regulations, which may differ from accounting principles generally accepted in the United States.

F-6

Derivative Financial Instruments
The Fund may invest in certain derivative financial instruments including futures, forward, swap and option contracts, and other financial instruments with similar characteristics. Although the Fund is authorized to invest in such financial instruments, and may do so in the future, it did not make any such investments during the period November 19, 2003 (commencement of operations) through December 29, 2003.

Custodian Fee Credit
The Fund has an arrangement with the custodian bank whereby certain custodian fees and expenses are reduced by credits earned on the Fund's cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. During the period November 19, 2003 (commencement of operation) through December 29, 2003 no such credit was recorded.

Organization and Offering Costs
Nuveen Investments, LLC, has agreed to reimburse all organization expenses
($11,500) and pay all Common share offering costs (other than the sales load)
that exceed $.03 per Common share. The Fund's share of offering costs ($675,000) were recorded as a reduction of the proceeds from the sale of Common shares.

If the Fund offers MuniPreferred shares, the offering costs will be borne by Common shareholders as a direct reduction to paid-in surplus.

Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets applicable to Common shares from operations during the reporting period. Actual results may differ from those estimates.

2. FUND SHARES The Fund sold 22,500,000 Common shares during the period November 19, 2003 (commencement of operations) through December 29, 2003.

3. SECURITIES TRANSACTIONS Purchases and sales (including maturities) of investments in long-term municipal securities for the period November 19, 2003 (commencement of operations) through December 29, 2003, were as follows:

--------------------------------------------------------------------------------
Purchases                                  $378,987,262

Sales and maturities                         61,505,049
                                           ============
--------------------------------------------------------------------------------

4. INCOME TAX INFORMATION The following information is presented on an income tax basis as of December 29, 2003. Differences between amounts for financial statement and federal income tax purposes are primarily due to timing differences in recognizing income on taxable market discount securities and timing differences in recognizing certain gains and losses on security transactions.

--------------------------------------------------------------------------------
Cost of investments                                                 $318,111,292

  depreciation                                                           (81,315)

For the next $250 million                                                               .7250
For the next $500 million                                                               .7125
For the next $1 billion                                                                 .7000

======================================================================================================

The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities.

NUVEEN MUNICIPAL HIGH INCOME OPPORTUNITY FUND, a Massachusetts business trust (the "Fund"), certifies that:

First: Pursuant to authority expressly vested in the Board of Trustees of the Fund by Article IV of the Fund's Declaration of Trust (which, as hereafter restated or amended from time to time is, together with this Statement, herein called the "Declaration"), the Board of Trustees has, by resolution, authorized the issuance of shares of the Fund's authorized Preferred Shares liquidation preference $25,000 per share, having such designation or designations as to series as is set forth in Section 1 of Appendix A hereto and such number of shares per such series as is set forth in Section 2 of Appendix A hereto.

Second: The preferences, voting powers, restrictions, limitations as to dividends, qualifications, and terms and conditions of redemption, of the shares of each series of MuniPreferred described in Section 1 of Appendix A hereto are as follows (each such series being referred to herein as a series of MuniPreferred, and shares of all such series being referred to herein individually as a share of MuniPreferred and collectively as shares of MuniPreferred):

DEFINITIONS

Except as otherwise specifically provided in Section 3 of Appendix A hereto, as used in Parts I and II of this Statement, the following terms shall have the following meanings (with terms defined in the singular having comparable meanings when used in the plural and vice versa), unless the context otherwise requires:

(a) "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

1

"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.

(b) "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 trustees, directors, or executive officers of which is a trustee of the Fund be deemed to be an Affiliate solely because such trustee, director or executive officer is also a trustee of the Fund.

(c) "AGENT MEMBER" shall mean a member of or participant in the Securities Depository that will act on behalf of a Bidder.

(d) "ALL HOLD ORDER" shall have the meaning specified in Section 12 of Appendix A of this Statement.

(e) "ANTICIPATION NOTES" shall mean Tax Anticipation Notes (TANs), Revenue Anticipation Notes (RANs), Tax and Revenue Anticipation Notes (TRANs), Grant Anticipation Notes (GANs) that are rated by S&P and Bond Anticipation Notes (BANs) that are rated by S&P.

(f) "APPLICABLE RATE" shall have the meaning specified in subparagraph
(e)(i) of Section 2 of Part I of this Statement.

(g) "AUCTION" shall mean each periodic implementation of the Auction Procedures.

(h) "AUCTION AGENCY AGREEMENT" shall mean the agreement between the Fund and the Auction Agent which provides, among other things, that the Auction Agent will follow the Auction Procedures for purposes of determining the Applicable Rate for shares of a series of MuniPreferred so long as the Applicable Rate for shares of such series is to be based on the results of an Auction.

(i) "AUCTION AGENT" shall mean the entity appointed as such by a resolution of the Board of Trustees in accordance with Section 6 of Part II of this Statement.

(j) "AUCTION DATE," with respect to any Rate Period, shall mean the Business Day next preceding the first day of such Rate Period.

(k) "AUCTION PROCEDURES" shall mean the procedures for conducting Auctions set forth in Part II of this Statement.

(l) "AVAILABLE MUNIPREFERRED" shall have the meaning specified in paragraph (a) of Section 3 of Part II of this Statement.

(m) "BENCHMARK RATE" shall have the meaning specified in Section 12 of Appendix A hereto.

2

(n) "BENEFICIAL OWNER," with respect to shares of a series of MuniPreferred, means a customer of a Broker-Dealer who is listed on the records of that Broker-Dealer (or, if applicable, the Auction Agent) as a holder of shares of such series.

(o) "BID" and "BIDS" shall have the respective meanings specified in paragraph (a) of Section 1 of Part II of this Statement.

(p) "BIDDER" and "BIDDERS" shall have the respective meanings specified in paragraph (a) of Section 1 of Part II of this Statement; provided, however, that neither the Fund nor any affiliate thereof shall be permitted to be a Bidder in an Auction, except that any Broker-Dealer that is an affiliate of the Fund may be a Bidder in an Auction, but only if the Orders placed by such Broker-Dealer are not for its own account.

Section 2 and the Fund shall have paid to the Auction Agent a late charge ("Late Charge") equal to the sum of (1) if such Failure to Deposit consisted of the failure timely to pay to the Auction Agent the full amount of dividends with respect to any Dividend Period of the shares of such series, an amount computed by multiplying (x) 200% of the Reference Rate for the Rate Period during which such Failure to Deposit occurs on the Dividend Payment Date for such Dividend Period by (y) a fraction, the numerator of which shall be the number of days for which such Failure to Deposit has not been cured in accordance with paragraph (f) of this Section 2 (including the day such Failure to Deposit occurs and excluding the day such Failure to Deposit is cured) and the denominator of which shall be 360, and applying the rate obtained against the aggregate Liquidation Preference of the outstanding shares of such series and (2) if such Failure to Deposit consisted of the failure timely to pay to the Auction Agent the Redemption Price of the shares, if any, of such series for which Notice of Redemption has been mailed by the Fund pursuant to paragraph (c) of Section 11 of this Part I, an amount computed by multiplying (x) 200% of the Reference Rate for the Rate Period during which such Failure to Deposit occurs on the redemption date by (y) a fraction, the numerator of which shall be the number of days for which such Failure to Deposit is not cured in accordance with paragraph (f) of this Section
2 (including the day such Failure to Deposit occurs and excluding the day such Failure to Deposit is cured) and the denominator of which shall be 360, and applying the rate obtained against the aggregate Liquidation Preference of the outstanding shares of such series to be redeemed, no Auction will be held in respect of shares of such series for the Subsequent Rate Period thereof and the dividend rate for shares of such series for such Subsequent Rate Period will be the Maximum Rate for shares of such series on the Auction Date for such Subsequent Rate Period;

(C) any Failure to Deposit shall have occurred with respect to shares of such series during any Rate Period thereof (other than any Special Rate Period

14

consisting of more than 364 Rate Period Days or any Rate Period succeeding any Special Rate Period consisting of more than 364 Rate Period Days during which a Failure to Deposit occurred that has not been cured), and, prior to 12:00 Noon, New York City time, on the third Business Day next succeeding the date on which such Failure to Deposit occurred, such Failure to Deposit shall not have been cured in accordance with paragraph (f) of this Section 2 or the Fund shall not have paid the applicable Late Charge to the Auction Agent, no Auction will be held in respect of shares of such series for the first Subsequent Rate Period thereof thereafter (or for any Rate Period thereof thereafter to and including the Rate Period during which (1) such Failure to Deposit is cured in accordance with paragraph (f) of this Section 2 and (2) the Fund pays the applicable Late Charge to the Auction Agent (the condition set forth in this clause (2) to apply only in the event Moody's is rating such shares at the time the Fund cures such Failure to Deposit), in each case no later than 12:00 Noon, New York City time, on the fourth Business Day prior to the end of such Rate Period), and the dividend rate for shares of such series for each such Subsequent Rate Period shall be a rate per annum equal to the Maximum Rate for shares of such series on the Auction Date for such Subsequent Rate Period (but with the prevailing rating for shares of such series, for purposes of determining such Maximum Rate, being deemed to be "Below "ba3"/BB2"); or

(D) any Failure to Deposit shall have occurred with respect to shares of such series during a Special Rate Period thereof consisting of more than 364 Rate Period Days, or during any Rate Period thereof succeeding any Special Rate Period consisting of more than 364 Rate Period Days during which a Failure to Deposit occurred that has not been cured, and, prior to 12:00 Noon, New York City time, on the fourth Business Day preceding the Auction Date for the Rate Period subsequent to such Rate Period, such Failure to Deposit shall not have been cured in accordance with paragraph (f) of this
Section 2 or, in the event Moody's is then rating such shares, the Fund shall not have paid the applicable Late Charge to the Auction Agent (such Late Charge, for purposes of this subparagraph (D), to be calculated by using, as the Reference Rate, the Reference Rate applicable to a Rate Period (x) consisting of more than 182 Rate Period Days but fewer than 365 Rate Period Days and (y) commencing on the date on which the Rate Period during which Failure to Deposit occurs commenced), no Auction will be held in respect of shares of such series for such Subsequent Rate Period (or for any Rate Period thereof thereafter to and including the Rate Period during which (1) such Failure to Deposit is cured in accordance with paragraph (f) of this Section 2 and (2) the Fund pays the applicable Late Charge to the Auction Agent (the condition set forth in this clause (2) to apply only in the event Moody's is rating such shares at the time the Fund cures such Failure to Deposit), in each case no later than 12:00 Noon, New York City time, on the fourth Business Day prior to the end of such Rate Period), and the dividend rate for shares of such series for each such Subsequent Rate Period shall be a rate per annum equal to the Maximum Rate for shares of such series on the Auction Date for such Subsequent Rate Period (but with the prevailing rating for shares of such series, for purposes of determining such Maximum Rate, being deemed to be "Below "ba3"/BB2") (the rate per annum at which dividends are payable on shares of a series of MuniPreferred for any Rate Period thereof being herein referred to as the "Applicable Rate" for shares of such series).

(ii) CALCULATION OF DIVIDENDS. The amount of dividends per share payable on shares of a series of MuniPreferred on any date on which dividends shall be payable on shares of such series shall be computed by multiplying the Applicable Rate for shares of such series in effect for such Dividend Period or Dividend Periods or part thereof for which dividends have not

15

been paid by a fraction, the numerator of which shall be the number of days in such Dividend Period or Dividend Periods or part thereof and the denominator of which shall be 365 if such Dividend Period consists of 7 Rate Period Days and 360 for all other Dividend Periods, and applying the rate obtained against $25,000.

(f) CURING A FAILURE TO DEPOSIT. A Failure to Deposit with respect to shares of a series of MuniPreferred shall have been cured (if such Failure to Deposit is not solely due to the willful failure of the Fund to make the required payment to the Auction Agent) with respect to any Rate Period of shares of such series if, within the respective time periods described in subparagraph
(e)(i) of this Section 2, the Fund shall have paid to the Auction Agent (A) all accumulated and unpaid dividends on shares of such series and (B) without duplication, the Redemption Price for shares, if any, of such series for which Notice of Redemption has been mailed by the Fund pursuant to paragraph (c) of
Section 11 of Part I of this Statement; provided, however, that the foregoing clause (B) shall not apply to the Fund's failure to pay the Redemption Price in respect of shares of MuniPreferred when the related Redemption Notice provides that redemption of such shares is subject to one or more conditions precedent and any such condition precedent shall not have been satisfied at the time or times and in the manner specified in such Notice of Redemption.

(g) DIVIDEND PAYMENTS BY FUND TO AUCTION AGENT. The Fund shall pay to
the Auction Agent, not later than 12:00 Noon, New York City time, on the Business Day next preceding each Dividend Payment Date for shares of a series of MuniPreferred, an aggregate amount of funds available on the next Business Day in The City of New York, New York, equal to the dividends to be paid to all Holders of shares of such series on such Dividend Payment Date.

(h) AUCTION AGENT AS TRUSTEE OF DIVIDEND PAYMENTS BY FUND. All moneys paid to the Auction Agent for the payment of dividends (or for the payment of any Late Charge) shall be held in trust for the payment of such dividends (and any such Late Charge) by the Auction Agent for the benefit of the Holders specified in paragraph (i) of this Section 2. Any moneys paid to the Auction Agent in accordance with the foregoing but not applied by the Auction Agent to the payment of dividends (and any such Late Charge) will, to the extent permitted by law, be repaid to the Fund at the end of 90 days from the date on which such moneys were so to have been applied.

(i) DIVIDENDS PAID TO HOLDERS. Each dividend on shares of MuniPreferred shall be paid on the Dividend Payment Date therefor to the Holders thereof as their names appear on the record books of the Fund on the Business Day next preceding such Dividend Payment Date.

(j) DIVIDENDS CREDITED AGAINST EARLIEST ACCUMULATED BUT UNPAID DIVIDENDS. Any dividend payment made on shares of MuniPreferred shall first be credited against the earliest accumulated but unpaid dividends due with respect to such shares. Dividends in arrears for any past Dividend Period may be declared and paid at any time, without reference to any regular Dividend Payment Date, to the Holders as their names appear on the record books of the Fund on such date, not exceeding 15 days preceding the payment date thereof, as may be fixed by the Board of Trustees.

(k) DIVIDENDS DESIGNATED AS EXEMPT-INTEREST DIVIDENDS. Dividends on shares of MuniPreferred shall be designated as exempt-interest dividends up to the amount of tax-exempt income of the Fund, to the extent permitted by, and for purposes of, Section 852 of the Code.

3. GROSS-UP PAYMENTS. Holders of shares of MuniPreferred shall be entitled to receive, when, as and if declared by the Board of Trustees, out of funds legally available therefor, dividends in an amount equal to the aggregate Gross-up Payments as follows:

16

(a) MINIMUM RATE PERIODS AND SPECIAL RATE PERIODS OF 28 RATE PERIOD
DAYS OR FEWER. If, in the case of any Minimum Rate Period or any Special Rate Period of 28 Rate Period Days or fewer, the Fund allocates any net capital gains or other income taxable for Federal income tax purposes to a dividend paid on shares of MuniPreferred without having given advance notice thereof to the Auction Agent as provided in Section 5 of Part II of this Statement (such allocation being referred to herein as a "Taxable Allocation") solely by reason of the fact that such allocation is made retroactively as a result of the redemption of all or a portion of the outstanding shares of MuniPreferred or the liquidation of the Fund, the Fund shall, prior to the end of the calendar year in which such dividend was paid, provide notice thereof to the Auction Agent and direct the Fund's dividend disbursing agent to send such notice with a Gross-up Payment to each Holder of such shares that was entitled to such dividend payment during such calendar year at such Holder's address as the same appears or last appeared on the record books of the Fund.

(b) SPECIAL RATE PERIODS AND INITIAL RATE PERIODS OF MORE THAN 28
RATE PERIOD DAYS. If, in the case of any Special Rate Period and Initial Rate Period of more than 28 Rate Period Days, the Fund makes a Taxable Allocation to a dividend paid on shares of MuniPreferred, the Fund shall, prior to the end of the calendar year in which such dividend was paid, provide notice thereof to the Auction Agent and direct the Fund's dividend disbursing agent to send such notice with a Gross-up Payment to each Holder of shares that was entitled to such dividend payment during such calendar year at such Holder's address as the same appears or last appeared on the record books of the Fund.

(c) NO GROSS-UP PAYMENTS IN THE EVENT OF A REALLOCATION. The Fund shall not be required to make Gross-up Payments with respect to any net capital gains or other taxable income determined by the Internal Revenue Service to be allocable in a manner different from that allocated by the Fund.

4. DESIGNATION OF SPECIAL RATE PERIODS.

(a) LENGTH OF AND PRECONDITIONS FOR SPECIAL RATE PERIOD. The Fund, at its option, may designate any succeeding Subsequent Rate Period of shares of a series of MuniPreferred as a Special Rate Period consisting of a specified number of Rate Period Days evenly divisible by seven and not more than 1,820, subject to adjustment as provided in paragraph (b) of this Section 4. A designation of a Special Rate Period shall be effective only if (A) notice thereof shall have been given in accordance with paragraph (c) and subparagraph
(d)(i) of this Section 4, (B) an Auction for shares of such series shall have been held on the Auction Date immediately preceding the first day of such proposed Special Rate Period and Sufficient Clearing Bids for shares of such series shall have existed in such Auction, and (C) if any Notice of Redemption shall have been mailed by the Fund pursuant to paragraph (c) of Section 11 of this Part I with respect to any shares of such series, the Redemption Price with respect to such shares shall have been deposited with the Auction Agent. In the event the Fund wishes to designate any succeeding Subsequent Rate Period for shares of a series of MuniPreferred as a Special Rate Period consisting of more than 28 Rate Period Days, the Fund shall notify S&P (if S&P is then rating such series) and Moody's (if Moody's is then rating such series) in advance of the commencement of such Subsequent Rate Period that the Fund wishes to designate such Subsequent Rate Period as a Special Rate Period and shall provide S&P (if S&P is then rating such series) and Moody's (if Moody's is then rating such series) with such documents as either may request.

(b) ADJUSTMENT OF LENGTH OF SPECIAL RATE PERIOD. In the event the Fund wishes to designate a Subsequent Rate Period as a Special Rate Period, but the day following what would otherwise be the last day of such Special Rate Period is not (a) a Tuesday that is a Business Day in the case of a series of MuniPreferred designated as "Series M MuniPreferred" in Section 1 of Appendix A hereto, (b) a Wednesday that is a Business Day in the case of a series of MuniPreferred designated as "Series T

17

MuniPreferred" in Section 1 of Appendix A hereto, (c) a Thursday that is a Business Day in the case of a series of MuniPreferred designated as "Series W MuniPreferred" in Section 1 of Appendix A hereto, (d) a Friday that is a Business Day in the case of a series of MuniPreferred designated as "Series TH MuniPreferred" in Section 1 of Appendix A hereto, or (e) a Monday that is a Business Day in the case of a series of MuniPreferred designated as "Series F MuniPreferred" in Section 1 of Appendix A hereto, then the Fund shall designate such Subsequent Rate Period as a Special Rate Period consisting of the period commencing on the first day following the end of the immediately preceding Rate Period and ending (a) on the first Monday that is followed by a Tuesday that is a Business Day preceding what would otherwise be such last day, in the case of Series M MuniPreferred, (b) on the first Tuesday that is followed by a Wednesday that is a Business Day preceding what would otherwise be such last day, in the case of Series T MuniPreferred, (c) on the first Wednesday that is followed by a Thursday that is a Business Day preceding what would otherwise be such last day, in the case of Series W MuniPreferred, (d) on the first Thursday that is followed by a Friday that is a Business Day preceding what would otherwise be such last day, in the case of Series TH MuniPreferred, and (e) on the first Sunday that is followed by a Monday that is a Business Day preceding what would otherwise be such last day, in the case of Series F MuniPreferred.

(c) NOTICE OF PROPOSED SPECIAL RATE PERIOD. If the Fund proposes to designate any succeeding Subsequent Rate Period of shares of a series of MuniPreferred as a Special Rate Period pursuant to paragraph (a) of this Section 4, not less than 20 (or such lesser number of days as may be agreed to from time to time by the Auction Agent) nor more than 30 days prior to the date the Fund proposes to designate as the first day of such Special Rate Period (which shall be such day that would otherwise be the first day of a Minimum Rate Period), notice shall be (i) published or caused to be published by the Fund in a newspaper of general circulation to the financial community in The City of New York, New York, which carries financial news, and (ii) mailed by the Fund by first-class mail, postage prepaid, to the Holders of shares of such series. Each such notice shall state (A) that the Fund may exercise its option to designate a succeeding Subsequent Rate Period of shares of such series as a Special Rate Period, specifying the first day thereof and (B) that the Fund will, by 11:00
A.M., New York City time, on the second Business Day next preceding such date (or by such later time or date, or both, as may be agreed to by the Auction Agent) notify the Auction Agent of either (x) its determination, subject to certain conditions, to exercise such option, in which case the Fund shall specify the Special Rate Period designated, or (y) its determination not to exercise such option.

(d) NOTICE OF SPECIAL RATE PERIOD. No later than 11:00 A.M., New York City time, on the second Business Day next preceding the first day of any proposed Special Rate Period of shares of a series of MuniPreferred as to which notice has been given as set forth in paragraph (c) of this Section 4 (or such later time or date, or both, as may be agreed to by the Auction Agent), the Fund shall deliver to the Auction Agent either:

(i) a notice ("Notice of Special Rate Period") stating (A) that the Fund has determined to designate the next succeeding Rate Period of shares of such series as a Special Rate Period, specifying the same and the first day thereof, (B) the Auction Date immediately prior to the first day of such Special Rate Period, (C) that such Special Rate Period shall not commence if (1) an Auction for shares of such series shall not be held on such Auction Date for any reason or
(2) an Auction for shares of such series shall be held on such Auction Date but Sufficient Clearing Bids for shares of such series shall not exist in such Auction, (D) the scheduled Dividend Payment Dates for shares of such series during such Special Rate Period and (E) the Special Redemption Provisions, if any, applicable to shares of such series in respect of such Special Rate Period, such notice to be accompanied by a MuniPreferred Basic Maintenance Report showing that, as of the third Business Day next preceding such proposed Special Rate Period, Moody's Eligible Assets (if Moody's is then rating such series) and S&P Eligible Assets

18

(if S&P is then rating such series) each have an aggregate Discounted Value at least equal to the MuniPreferred Basic Maintenance Amount as of such Business Day (assuming for purposes of the foregoing calculation that (a) the Maximum Rate is the Maximum Rate on such Business Day as if such Business Day were the Auction Date for the proposed Special Rate Period, and (b) the Moody's Discount Factors applicable to Moody's Eligible Assets are 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 herein); or

(ii) a notice stating that the Fund has determined not to exercise its option to designate a Special Rate Period of shares of such series and that the next succeeding Rate Period of shares of such series shall be a Minimum Rate Period.

(e) FAILURE TO DELIVER NOTICE OF SPECIAL RATE PERIOD. If the Fund fails to deliver either of the notices described in subparagraphs (d)(i) or
(d)(ii) of this Section 4 (and, in the case of the notice described in subparagraph (d)(i) of this Section 4, a MuniPreferred Basic Maintenance Report to the effect set forth in such subparagraph (if either Moody's or S&P is then rating the series in question)) with respect to any designation of any proposed Special Rate Period to the Auction Agent by 11:00 A.M., New York City time, on the second Business Day next preceding the first day of such proposed Special Rate Period (or by such later time or date, or both, as may be agreed to by the Auction Agent), the Fund shall be deemed to have delivered a notice to the Auction Agent with respect to such Special Rate Period to the effect set forth in subparagraph (d)(ii) of this Section 4. In the event the Fund delivers to the Auction Agent a notice described in subparagraph (d)(i) of this Section 4, it shall file a copy of such notice with the Secretary of the Fund, and the contents of such notice shall be binding on the Fund. In the event the Fund delivers to the Auction Agent a notice described in subparagraph (d)(ii) of this
Section 4, the Fund will provide Moody's (if Moody's is then rating the series in question) and S&P (if S&P is then rating the series in question) a copy of such notice.

5. VOTING RIGHTS.

(a) ONE VOTE PER SHARE OF MUNIPREFERRED. Except as otherwise provided in the Declaration of Trust or as otherwise required by law, (i) each Holder of shares of MuniPreferred shall be entitled to one vote for each share of MuniPreferred held by such Holder on each matter submitted to a vote of shareholders of the Fund, and (ii) the holders of outstanding Preferred Shares, including each share of MuniPreferred, and of Common Shares shall vote together as a single class; provided, however, that, at any meeting of the shareholders of the Fund held for the election of trustees, the holders of outstanding Preferred Shares, including MuniPreferred, represented in person or by proxy at said meeting, shall be entitled, as a class, to the exclusion of the holders of all other securities and classes of shares of beneficial interest of the Fund, to elect two trustees of the Fund, each Preferred Share, including each share of MuniPreferred, entitling the holder thereof to one vote. Subject to paragraph
(b) of this Section 5, the holders of outstanding Common Shares and Preferred Shares, including MuniPreferred, voting together as a single class, shall elect the balance of the trustees.

(b) VOTING FOR ADDITIONAL TRUSTEES.

(i) VOTING PERIOD. During any period in which any one or more of the conditions described in subparagraphs (A) or (B) of this subparagraph (b)(i) shall exist (such period being referred to herein as a "Voting Period"), the number of trustees constituting the Board of Trustees shall be automatically increased by the smallest number that, when added to the two trustees elected exclusively by the holders of Preferred Shares, including shares of MuniPreferred, would constitute a majority of the Board of Trustees as so increased by such smallest number; and the holders of Preferred Shares, including MuniPreferred, shall be entitled, voting as a class on a one-vote-per-share basis (to the exclusion of the holders of all other

19

securities and classes of shares of beneficial interest of the Fund), to elect such smallest number of additional trustees, together with the two trustees that such holders are in any event entitled to elect. A Voting Period shall commence:

(A) if at the close of business on any dividend payment date accumulated dividends (whether or not earned or declared) on any outstanding Preferred Share, including MuniPreferred, equal to at least two full years' dividends shall be due and unpaid and sufficient cash or specified securities shall not have been deposited with the Auction Agent for the payment of such accumulated dividends; or

(B) if at any time holders of Preferred Shares are entitled under the 1940 Act to elect a majority of the trustees of the Fund.

Upon the termination of a Voting Period, the voting rights described in this subparagraph (b)(i) shall cease, subject always, however, to the revesting of such voting rights in the Holders upon the further occurrence of any of the events described in this subparagraph (b)(i).

(ii) NOTICE OF SPECIAL MEETING. As soon as practicable after the accrual of any right of the holders of Preferred Shares to elect additional trustees as described in subparagraph (b)(i) of this Section 5, the Fund shall notify the Auction Agent and the Auction Agent shall instruct the Trustees to call a special meeting of such holders, and the Auction Agent shall mail a notice of such special meeting to such holders, such meeting to be held not less than 10 nor more than 20 days after the date of mailing of such notice. If the Fund fails to send such notice to the Auction Agent or if a special meeting is not called, it may be called by any such holder on like notice. The record date for determining the holders entitled to notice of and to vote at such special meeting shall be the close of business on the fifth Business Day preceding the day on which such notice is mailed. At any such special meeting and at each meeting of holders of Preferred Shares held during a Voting Period at which trustees are to be elected, such holders, voting together as a class (to the exclusion of the holders of all other securities and classes of shares of beneficial interest of the Fund), shall be entitled to elect the number of trustees prescribed in subparagraph (b)(i) of this Section 5 on a one-vote-per-share basis.

(iii) TERMS OF OFFICE OF EXISTING TRUSTEES. The terms of office of all persons who are trustees of the Fund at the time of a special meeting of Holders and holders of other Preferred Shares to elect trustees shall continue, notwithstanding the election at such meeting by the Holders and such other holders of the number of trustees that they are entitled to elect, and the persons so elected by the Holders and such other holders, together with the two incumbent trustees elected by the Holders and such other holders of Preferred Shares and the remaining incumbent trustees elected by the holders of the Common Shares and Preferred Shares, shall constitute the duly elected trustees of the Fund.

(iv) TERMS OF OFFICE OF CERTAIN TRUSTEES TO TERMINATE UPON TERMINATION OF VOTING PERIOD. Simultaneously with the termination of a Voting Period, the terms of office of the additional trustees elected by the Holders and holders of other Preferred Shares pursuant to subparagraph (b)(i) of this Section 5 shall terminate, the remaining trustees shall constitute the trustees of the Fund and the voting rights of the Holders and such other holders to elect additional trustees pursuant to subparagraph (b)(i) of this Section 5 shall cease, subject to the provisions of the last sentence of subparagraph (b)(i) of this Section 5.

20

(c) HOLDERS OF MUNIPREFERRED TO VOTE ON CERTAIN OTHER MATTERS.

(i) INCREASES IN CAPITALIZATION. So long as any shares of MuniPreferred are outstanding, the Fund shall not, without the affirmative vote or consent of the Holders of at least a majority of the shares of MuniPreferred outstanding at the time, in person or by proxy, either in writing or at a meeting, voting as a separate class:
(a) authorize, create or issue any class or series of shares ranking prior to or on a parity with shares of MuniPreferred with respect to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Fund, or authorize, create or issue additional shares of any series of MuniPreferred (except that, notwithstanding the foregoing, but subject to the provisions of Section 10 of this Part I, the Board of Trustees, without the vote or consent of the Holders of MuniPreferred, may from time to time authorize and create, and the Fund may from time to time issue additional shares of, any series of MuniPreferred, or classes or series of Preferred Shares 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; provided, however, that if Moody's or S&P is not then rating the shares of MuniPreferred, the aggregate liquidation preference of all Preferred Shares of the Fund outstanding after any such issuance, exclusive of accumulated and unpaid dividends, may not exceed the amount set forth in Section 10 of Appendix A hereto) or (b) amend, alter or repeal the provisions of the Declaration, or this Statement, whether by merger, consolidation or otherwise, so as to affect any preference, right or power of such shares of MuniPreferred or the Holders thereof; provided, however, that (i) none of the actions permitted by the exception to (a) above will be deemed to affect such preferences, rights or powers, (ii) a division of a share of MuniPreferred will be deemed to affect such preferences, rights or powers only if the terms of such division adversely affect the Holders of shares of MuniPreferred and (iii) the authorization, creation and issuance of classes or series of shares ranking junior to 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, will be deemed to affect such preferences, rights or powers only if Moody's or S&P is then rating shares of MuniPreferred and such issuance would, at the time thereof, cause the Fund not to satisfy the 1940 Act MuniPreferred Asset Coverage or the MuniPreferred Basic Maintenance Amount. So long as any shares of MuniPreferred are outstanding, the Fund shall not, without the affirmative vote or consent of the Holders of at least 66 2/3% of the shares of MuniPreferred outstanding at the time, in person or by proxy, either in writing or at a meeting, voting as a separate class, file a voluntary application for relief under Federal bankruptcy law or any similar application under state law for so long as the Fund is solvent and does not foresee becoming insolvent. If any action set forth above would adversely affect the rights of one or more series (the "Affected Series") of MuniPreferred in a manner different from any other series of MuniPreferred, the Fund will not approve any such action without the affirmative vote or consent of the Holders of at least a majority of the shares of each such Affected Series outstanding at the time, in person or by proxy, either in writing or at a meeting (each such Affected Series voting as a separate class).

(ii) 1940 ACT MATTERS. Unless a higher percentage is provided for in the Declaration, (A) the affirmative vote of the Holders of at least a majority of the Preferred Shares, including MuniPreferred, outstanding at the time, voting as a separate class, shall be required to approve any conversion of the Fund from a closed-end to an open-end investment company and (B) the affirmative vote of the Holders of a "majority of the outstanding Preferred Shares," including MuniPreferred, voting as a separate class, shall be required to approve any plan of reorganization (as such term is used in the 1940 Act) adversely affecting such shares. The affirmative vote of the Holders of a "majority of the outstanding Preferred Shares," including MuniPreferred, voting as a separate class, shall be required to approve any action not described in

21

the first sentence of this Section 5(c)(ii) requiring a vote of security holders of the Fund under Section 13(a) of the 1940 Act. For purposes of the foregoing, "majority of the outstanding Preferred Shares" means (i) 67% or more of such shares present at a meeting, if the Holders of more than 50% of such shares are present or represented by proxy, or (ii) more than 50% of such shares, whichever is less. In the event a vote of Holders of MuniPreferred is required pursuant to the provisions of Section 13(a) of the 1940 Act, the Fund shall, not later than ten Business Days prior to the date on which such vote is to be taken, notify Moody's (if Moody's is then rating the shares of MuniPreferred) and S&P (if S&P is then rating the shares of MuniPreferred) that such vote is to be taken and the nature of the action with respect to which such vote is to be taken. The Fund shall, not later than ten Business Days after the date on which such vote is taken, notify Moody's (if Moody's is then rating the shares of MuniPreferred) of the results of such vote.

(d) BOARD MAY TAKE CERTAIN ACTIONS WITHOUT SHAREHOLDER APPROVAL. The Board of Trustees, without the vote or consent of any holder of shares of Preferred Shares, including any series of MuniPreferred, or any other shareholder of the Fund, may from time to time adopt, amend, alter or repeal any or all of the definitions contained herein, add covenants and other obligations of the Fund, or confirm the applicability of covenants and other obligations set forth herein, in connection with obtaining or maintaining the rating of any Rating Agency which is then rating the MuniPreferred, and any such adoption, amendment, alteration or repeal will not be deemed to affect the preferences, rights or powers of Preferred Shares, including MuniPreferred, or the Holders thereof, provided that the Board of Trustees receives written confirmation from such Rating Agency, as applicable (with such confirmation in no event being required to be obtained from a particular Rating Agency with respect to definitions or other provisions relevant only to and adopted in connection with another Rating Agency's rating of any series of MuniPreferred) that any such amendment, alteration or repeal would not adversely affect the rating then assigned by such Rating Agency.

Notwithstanding anything herein to the contrary, the Rating Agency Guidelines, as they may be amended from time to time by the respective Rating Agency will be reflected in a written document and may be amended by the respective Rating Agency without the vote, consent or approval of the Fund, the Board of Trustees and any holder of shares of Preferred Shares, including any series of MuniPreferred, or any other shareholder of the Fund.

In addition, subject to compliance with applicable law, the Board of Trustees may amend the definition of Maximum Rate to increase the percentage amount by which the Reference Rate is multiplied to determine the Maximum Rate shown therein without the vote or consent of the holders of the Preferred Shares, including any series of MuniPreferred, or any other shareholder of the Fund, and without receiving any confirmation from any Rating Agency after consultation with the Broker-Dealers, provided that immediately following any such increase the Fund would be in compliance with the MuniPreferred Shares Basic Maintenance Amount.

(e) VOTING RIGHTS SET FORTH HEREIN ARE SOLE VOTING RIGHTS. Unless otherwise required by law, the Holders of shares of MuniPreferred shall not have any relative rights or preferences or other special rights other than those specifically set forth herein.

(f) NO PREEMPTIVE RIGHTS OR CUMULATIVE VOTING. The Holders of shares of MuniPreferred shall have no preemptive rights or rights to cumulative voting.

(g) VOTING FOR TRUSTEES SOLE REMEDY FOR FUND'S FAILURE TO PAY DIVIDENDS. In the event that the Fund fails to pay any dividends on the shares of MuniPreferred, the exclusive remedy of the Holders shall be the right to vote for trustees pursuant to the provisions of this Section 5.

22

(h) HOLDERS ENTITLED TO VOTE. For purposes of determining any rights of the Holders to vote on any matter, whether such right is created by this Statement, by the other provisions of the Declaration, by statute or otherwise, no Holder shall be entitled to vote any share of MuniPreferred and no share of MuniPreferred shall be deemed to be "outstanding" for the purpose of voting or determining the number of shares required to constitute a quorum if, prior to or concurrently with the time of determination of shares entitled to vote or shares deemed outstanding for quorum purposes, as the case may be, the requisite Notice of Redemption with respect to such shares shall have been mailed as provided in paragraph (c) of Section 11 of this Part I and the Redemption Price for the redemption of such shares shall have been deposited in trust with the Auction Agent for that purpose. No share of MuniPreferred held by the Fund or any affiliate of the Fund (except for shares held by a Broker-Dealer that is an affiliate of the Fund for the account of its customers) shall have any voting rights or be deemed to be outstanding for voting or other purposes.

6. 1940 ACT MUNIPREFERRED ASSET COVERAGE. The Fund shall maintain, as of the last Business Day of each month in which any share of MuniPreferred is outstanding, the 1940 Act MuniPreferred Asset Coverage.

7. MUNIPREFERRED BASIC MAINTENANCE AMOUNT.

(a) So long as shares of MuniPreferred are outstanding, the Fund shall maintain, on each Valuation Date, and shall verify to its satisfaction that it is maintaining on such Valuation Date, (i) S&P Eligible Assets having an aggregate Discounted Value equal to or greater than the MuniPreferred Basic Maintenance Amount (if S&P is then rating the shares of MuniPreferred) and (ii) Moody's Eligible Assets having an aggregate Discounted Value equal to or greater than the MuniPreferred Basic Maintenance Amount (if Moody's is then rating the shares of MuniPreferred).

(b) The Fund shall deliver to each Rating Agency which is then rating shares of MuniPreferred and any other party specified in the Rating Agency Guidelines all certificates that are set forth in the respective Rating Agency Guidelines regarding 1940 Act FundPreferred Shares Asset Coverage, MuniPreferred Basic Maintenance Amount and/or related calculations at such times and containing such information as set forth in the respective Rating Agency Guidelines (each, a "Rating Agency Certificate"). A failure by the Fund to deliver a Rating Agency Certificate with respect to the MuniPreferred Basic Maintenance Amount shall be deemed to be delivery of a Rating Agency Certificate indicating the Discounted Value for all assets of the Fund is less than the MuniPreferred Basic Maintenance Amount, as of the relevant Valuation Date.

8. [RESERVED].

9. RESTRICTIONS ON DIVIDENDS AND OTHER DISTRIBUTIONS.

(a) DIVIDENDS ON PREFERRED SHARES OTHER THAN MUNIPREFERRED. Except as set forth in the next sentence, no dividends shall be declared or paid or set apart for payment on the shares of any class or series of shares of beneficial interest of the Fund ranking, as to the payment of dividends, on a parity with shares of MuniPreferred for any period unless full cumulative dividends have been or contemporaneously are declared and paid on the shares of each series of MuniPreferred through its most recent Dividend Payment Date. When dividends are not paid in full upon the shares of each series of MuniPreferred through its most recent Dividend Payment Date or upon the shares of any other class or series of shares of beneficial interest of the Fund ranking on a parity as to the payment of dividends with shares of MuniPreferred through their most recent respective dividend payment dates, all dividends declared upon shares of MuniPreferred and any other such class or series of shares of beneficial interest ranking on a parity as to the payment of dividends with shares of MuniPreferred shall be declared pro rata so that the amount of dividends declared per share on shares of MuniPreferred and such other class or

23

series of shares of beneficial interest shall in all cases bear to each other the same ratio that accumulated dividends per share on the shares of MuniPreferred and such other class or series of shares of beneficial interest bear to each other (for purposes of this sentence, the amount of dividends declared per share of MuniPreferred shall be based on the Applicable Rate for such share for the Dividend Periods during which dividends were not paid in full).

(b) DIVIDENDS AND OTHER DISTRIBUTIONS WITH RESPECT TO COMMON SHARES UNDER THE 1940 ACT. The Board of Trustees shall not declare any dividend (except a dividend payable in Common Shares), or declare any other distribution, upon the Common Shares, or purchase Common Shares, unless in every such case the Preferred Shares have, at the time of any such declaration or purchase, an asset coverage (as defined in and determined pursuant to the 1940 Act) of at least 200% (or such other asset coverage as may in the future be specified in or under the 1940 Act as the minimum asset coverage for senior securities which are shares or stock of a closed-end investment company as a condition of declaring dividends on its common shares or stock) after deducting the amount of such dividend, distribution or purchase price, as the case may be.

(c) OTHER RESTRICTIONS ON DIVIDENDS AND OTHER DISTRIBUTIONS. For so long as any share of MuniPreferred is outstanding, and except as set forth in paragraph (a) of this Section 9 and paragraph (c) of Section 12 of this Part I, (A) the Fund shall not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or in options, warrants or rights to subscribe for or purchase, Common Shares or other shares, if any, ranking junior to the shares of MuniPreferred as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up) in respect of the Common Shares or any other shares of the Fund ranking junior to or on a parity with the shares of MuniPreferred as to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up, or call for redemption, redeem, purchase or otherwise acquire for consideration any Common Shares or any other such junior shares (except by conversion into or exchange for shares of the Fund ranking junior to the shares of MuniPreferred as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up), or any such parity shares (except by conversion into or exchange for shares of the Fund ranking junior to or on a parity with MuniPreferred as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up), unless
(i) full cumulative dividends on shares of each series of MuniPreferred through its most recently ended Dividend Period shall have been paid or shall have been declared and sufficient funds for the payment thereof deposited with the Auction Agent and (ii) the Fund has redeemed the full number of shares of MuniPreferred required to be redeemed by any provision for mandatory redemption pertaining thereto, and (B) the Fund shall not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or in options, warrants or rights to subscribe for or purchase, Common Shares or other shares, if any, ranking junior to shares of MuniPreferred as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up) in respect of Common Shares or any other shares of the Fund ranking junior to shares of MuniPreferred as to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up, or call for redemption, redeem, purchase or otherwise acquire for consideration any Common Shares or any other such junior shares (except by conversion into or exchange for shares of the Fund ranking junior to shares of MuniPreferred as to the payment of dividends and the distribution of assets upon dissolution, liquidation or winding up), unless immediately after such transaction the Discounted Value of Moody's Eligible Assets (if Moody's is then rating the shares of MuniPreferred) and S&P Eligible Assets (if S&P is then rating the shares of MuniPreferred) would each at least equal the MuniPreferred Basic Maintenance Amount.

10. RATING AGENCY RESTRICTIONS. For so long as any shares of MuniPreferred are Outstanding and any Rating Agency is then rating the shares of MuniPreferred, the Fund will not engage in certain proscribed transactions set forth in the Rating Agency Guidelines, unless it has received written

24

confirmation from each such Rating Agency that proscribes the applicable transaction in its Rating Agency Guidelines that any such action would not impair the rating then assigned by such Rating Agency to a series of MuniPreferred.

11. REDEMPTION.

(a) OPTIONAL REDEMPTION.

(i) Subject to the provisions of subparagraph (v) of this paragraph (a), shares of MuniPreferred of any series may be redeemed, at the option of the Fund, as a whole or from time to time in part, on the second Business Day preceding any Dividend Payment Date for shares of such series, out of funds legally available therefor, at a redemption price per share equal to the sum of $25,000 plus an amount equal to accumulated but unpaid dividends thereon (whether or not earned or declared) to (but not including) the date fixed for redemption; provided, however, that (1) shares of a series of MuniPreferred may not be redeemed in part if after such partial redemption fewer than 250 shares of such series remain outstanding; (2) unless otherwise provided in Section 11 of Appendix A hereto, shares of a series of MuniPreferred are redeemable by the Fund during the Initial Rate Period thereof only on the second Business Day next preceding the last Dividend Payment Date for such Initial Rate Period; and (3) subject to subparagraph (ii) of this paragraph (a), the Notice of Special Rate Period relating to a Special Rate Period of shares of a series of MuniPreferred, as delivered to the Auction Agent and filed with the Secretary of the Fund, may provide that shares of such series shall not be redeemable during the whole or any part of such Special Rate Period (except as provided in subparagraph (iv) of this paragraph
(a)) or shall be redeemable during the whole or any part of such Special Rate Period only upon payment of such redemption premium or premiums as shall be specified therein ("Special Redemption Provisions").

(ii) A Notice of Special Rate Period relating to shares of a series of MuniPreferred for a Special Rate Period thereof may contain Special Redemption Provisions only if the Fund's Board of Trustees, after consultation with the Broker-Dealer or Broker-Dealers for such Special Rate Period of shares of such series, determines that such Special Redemption Provisions are in the best interest of the Fund.

(iii) If fewer than all of the outstanding shares of a series of MuniPreferred are to be redeemed pursuant to subparagraph (i) of this paragraph (a), the number of shares of such series to be redeemed shall be determined by the Board of Trustees, and such shares shall be redeemed pro rata from the Holders of shares of such series in proportion to the number of shares of such series held by such Holders.

(iv) Subject to the provisions of subparagraph (v) of this paragraph (a), shares of any series of MuniPreferred may be redeemed, at the option of the Fund, as a whole but not in part, out of funds legally available therefor, on the first day following any Dividend Period thereof included in a Rate Period consisting of more than 364 Rate Period Days if, on the date of determination of the Applicable Rate for shares of such series for such Rate Period, such Applicable Rate equaled or exceeded on such date of determination the Treasury Note Rate for such Rate Period, at a redemption price per share equal to the sum of $25,000 plus an amount equal to accumulated but unpaid dividends thereon (whether or not earned or declared) to (but not including) the date fixed for redemption.

(v) The Fund may not on any date mail a Notice of Redemption pursuant to paragraph (c) of this Section 11 in respect of a redemption contemplated to be effected pursuant to this paragraph (a) unless on such date (a) the Fund has available Deposit Securities with

25

maturity or tender dates not later than the day preceding the applicable redemption date and having a value not less than the amount (including any applicable premium) due to Holders of shares of MuniPreferred by reason of the redemption of such shares on such redemption date and (b) the Discounted Value of Moody's Eligible Assets (if Moody's is then rating the 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. For purposes of determining in clause (b) of the preceding sentence whether the Discounted Value of Moody's Eligible Assets at least equals the MuniPreferred Basic Maintenance Amount, 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 herein.

(b) MANDATORY REDEMPTION. The Fund shall redeem, at a redemption price equal to $25,000 per share plus accumulated but unpaid dividends thereon (whether or not earned or declared) to (but not including) the date fixed by the Board of Trustees for redemption, certain of the shares of MuniPreferred, if the Fund fails to have either Moody's Eligible Assets with a Discounted Value or S&P Eligible Assets with a Discounted Value greater than or equal to the MuniPreferred Basic Maintenance Amount or fails to maintain the 1940 Act MuniPreferred Asset Coverage, in accordance with the requirements of the rating agency or agencies then rating the shares of MuniPreferred, and such failure is not cured on or before the MuniPreferred Basic Maintenance Cure Date or the 1940 Act Cure Date, as the case may be. The number of shares of MuniPreferred to be redeemed shall be equal to the lesser of (i) the minimum number of shares of MuniPreferred, together with all other Preferred Shares subject to redemption or retirement, the redemption of which, if deemed to have occurred immediately prior to the opening of business on the Cure Date, would have resulted in the Fund's having both Moody's Eligible Assets with a Discounted Value and S&P Eligible Assets with a Discounted Value greater than or equal to the MuniPreferred Basic Maintenance Amount or maintaining the 1940 Act MuniPreferred Asset Coverage, as the case may be, on such Cure Date (provided, however, that if there is no such minimum number of shares of MuniPreferred and other Preferred Shares the redemption or retirement of which would have had such result, all shares of MuniPreferred and Preferred Shares then outstanding shall be redeemed), and (ii) the maximum number of shares of MuniPreferred, together with all other Preferred Shares subject to redemption or retirement, that can be redeemed out of funds expected to be legally available therefor in accordance with the Declaration and applicable law. In determining the shares of MuniPreferred required to be redeemed in accordance with the foregoing, the Fund shall allocate the number required to be redeemed to satisfy the MuniPreferred Basic Maintenance Amount or the 1940 Act MuniPreferred Asset Coverage, as the case may be, pro rata among shares of MuniPreferred and other Preferred Shares (and, then, pro rata among each series of MuniPreferred) subject to redemption or retirement. The Fund shall effect such redemption on the date fixed by the Fund therefor, which date shall not be earlier than 20 days nor later than 40 days after such Cure Date, except that if the Fund does not have funds legally available for the redemption of all of the required number of shares of MuniPreferred and other Preferred Shares which are subject to redemption or retirement or the Fund otherwise is unable to effect such redemption on or prior to 40 days after such Cure Date, the Fund shall redeem those shares of MuniPreferred and other Preferred Shares which it was unable to redeem on the earliest practicable date on which it is able to effect such redemption. If fewer than all of the outstanding shares of a series of MuniPreferred are to be redeemed pursuant to this paragraph (b), the number of shares of such series to be redeemed shall be redeemed pro rata from the Holders of shares of such series in proportion to the number of shares of such series held by such Holders.

(c) NOTICE OF REDEMPTION. If the Fund shall determine or be required to redeem shares of a series of MuniPreferred pursuant to paragraph (a) or (b) of this Section 11, it shall mail a

26

Notice of Redemption with respect to such redemption by first class mail, postage prepaid, to each Holder of the shares of such series to be redeemed, at such Holder's address as the same appears on the record books of the Fund on the record date established by the Board of Trustees. Such Notice of Redemption shall be so mailed not less than 20 nor more than 45 days prior to the date fixed for redemption. Each such Notice of Redemption shall state: (i) the redemption date; (ii) the number of shares of MuniPreferred to be redeemed and the series thereof; (iii) the CUSIP number for shares of such series; (iv) the Redemption Price; (v) the place or places where the certificate(s) for such shares (properly endorsed or assigned for transfer, if the Board of Trustees shall so require and the Notice of Redemption shall so state) are to be surrendered for payment of the Redemption Price; (vi) that dividends on the shares to be redeemed will cease to accumulate on such redemption date; and
(vii) the provisions of this Section 11 under which such redemption is made. If fewer than all shares of a series of MuniPreferred held by any Holder are to be redeemed, the Notice of Redemption mailed to such Holder shall also specify the number of shares of such series to be redeemed from such Holder. The Fund may provide in any Notice of Redemption relating to a redemption contemplated to be effected pursuant to paragraph (a) of this Section 11 that such redemption is subject to one or more conditions precedent and that the Fund shall not be required to effect such redemption unless each such condition shall have been satisfied at the time or times and in the manner specified in such Notice of Redemption.

(d) NO REDEMPTION UNDER CERTAIN CIRCUMSTANCES. Notwithstanding the provisions of paragraphs (a) or (b) of this Section 11, if any dividends on shares of a series of MuniPreferred (whether or not earned or declared) are in arrears, no shares of such series shall be redeemed unless all outstanding shares of such series are simultaneously redeemed, and the Fund shall not purchase or otherwise acquire any shares of such series; provided, however, that the foregoing shall not prevent the purchase or acquisition of all outstanding shares of such series pursuant to the successful completion of an otherwise lawful purchase or exchange offer made on the same terms to, and accepted by, Holders of all outstanding shares of such series.

(e) ABSENCE OF FUNDS AVAILABLE FOR REDEMPTION. To the extent that any redemption for which Notice of Redemption has been mailed is not made by reason of the absence of legally available funds therefor in accordance with the Declaration and applicable law, such redemption shall be made as soon as practicable to the extent such funds become available. Failure to redeem shares of MuniPreferred shall be deemed to exist at any time after the date specified for redemption in a Notice of Redemption when the Fund shall have failed, for any reason whatsoever, to deposit in trust with the Auction Agent the Redemption Price with respect to any shares for which such Notice of Redemption has been mailed; provided, however, that the foregoing shall not apply in the case of the Fund's failure to deposit in trust with the Auction Agent the Redemption Price with respect to any shares where (1) the Notice of Redemption relating to such redemption provided that such redemption was subject to one or more conditions precedent and (2) any such condition precedent shall not have been satisfied at the time or times and in the manner specified in such Notice of Redemption. Notwithstanding the fact that the Fund may not have redeemed shares of MuniPreferred for which a Notice of Redemption has been mailed, dividends may be declared and paid on shares of MuniPreferred and shall include those shares of MuniPreferred for which a Notice of Redemption has been mailed.

(f) AUCTION AGENT AS TRUSTEE OF REDEMPTION PAYMENTS BY FUND. All moneys paid to the Auction Agent for payment of the Redemption Price of shares of MuniPreferred called for redemption shall be held in trust by the Auction Agent for the benefit of Holders of shares so to be redeemed.

(g) SHARES FOR WHICH NOTICE OF REDEMPTION HAS BEEN GIVEN ARE NO LONGER OUTSTANDING. Provided a Notice of Redemption has been mailed pursuant to paragraph (c) of this Section 11, upon the deposit with the Auction Agent (on the Business Day next preceding the date fixed

27

for redemption thereby, in funds available on the next Business Day in The City of New York, New York) of funds sufficient to redeem the shares of MuniPreferred that are the subject of such notice, dividends on such shares shall cease to accumulate and such shares shall no longer be deemed to be outstanding for any purpose, and all rights of the Holders of the shares so called for redemption shall cease and terminate, except the right of such Holders to receive the Redemption Price, but without any interest or other additional amount, except as provided in subparagraph (e)(i) of Section 2 of this Part I and in Section 3 of this Part I. Upon surrender in accordance with the Notice of Redemption of the certificates for any shares so redeemed (properly endorsed or assigned for transfer, if the Board of Trustees shall so require and the Notice of Redemption shall so state), the Redemption Price shall be paid by the Auction Agent to the Holders of shares of MuniPreferred subject to redemption. In the case that fewer than all of the shares represented by any such certificate are redeemed, a new certificate shall be issued, representing the unredeemed shares, without cost to the Holder thereof. The Fund shall be entitled to receive from the Auction Agent, promptly after the date fixed for redemption, any cash deposited with the Auction Agent in excess of (i) the aggregate Redemption Price of the shares of MuniPreferred called for redemption on such date and (ii) all other amounts to which Holders of shares of MuniPreferred called for redemption may be entitled. Any funds so deposited that are unclaimed at the end of 90 days from such redemption date shall, to the extent permitted by law, be repaid to the Fund, after which time the Holders of shares of MuniPreferred so called for redemption may look only to the Fund for payment of the Redemption Price and all other amounts to which they may be entitled. The Fund shall be entitled to receive, from time to time after the date fixed for redemption, any interest on the funds so deposited.

(h) COMPLIANCE WITH APPLICABLE LAW. In effecting any redemption pursuant to this Section 11, the Fund shall use its best efforts to comply with all applicable conditions precedent to effecting such redemption under the 1940 Act and any applicable Massachusetts law, but shall effect no redemption except in accordance with the 1940 Act and any applicable Massachusetts law.

(i) ONLY WHOLE SHARES OF MUNIPREFERRED MAY BE REDEEMED. In the case of any redemption pursuant to this Section 11, only whole shares of MuniPreferred shall be redeemed, and in the event that any provision of the Declaration would require redemption of a fractional share, the Auction Agent shall be authorized to round up so that only whole shares are redeemed.

12. LIQUIDATION RIGHTS.

(a) RANKING. The shares of a series of MuniPreferred shall rank on a parity with each other, with shares of any other series of MuniPreferred and with shares of any other series of Preferred Shares as to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Fund.

(b) DISTRIBUTIONS UPON LIQUIDATION. Upon the dissolution, liquidation or winding up of the affairs of the Fund, whether voluntary or involuntary, the Holders of shares of MuniPreferred then outstanding shall be entitled to receive and to be paid out of the assets of the Fund available for distribution to its shareholders, before any payment or distribution shall be made on the Common Shares or on any other class of shares of the Fund ranking junior to the MuniPreferred upon dissolution, liquidation or winding up, an amount equal to the Liquidation Preference with respect to such shares plus an amount equal to all dividends thereon (whether or not earned or declared) accumulated but unpaid to (but not including) the date of final distribution in same day funds, together with any payments required to be made pursuant to Section 3 of this Part I in connection with the liquidation of the Fund. After the payment to the Holders of the shares of MuniPreferred of the full preferential amounts provided for in this paragraph (b), the Holders of MuniPreferred as such shall have no right or claim to any of the remaining assets of the Fund.

28

(c) PRO RATA DISTRIBUTIONS. In the event the assets of the Fund available for distribution to the Holders of shares of MuniPreferred upon any dissolution, liquidation, or winding up of the affairs of the Fund, whether voluntary or involuntary, shall be insufficient to pay in full all amounts to which such Holders are entitled pursuant to paragraph (b) of this Section 12, no such distribution shall be made on account of any shares of any other class or series of Preferred Shares ranking on a parity with the shares of MuniPreferred with respect to the distribution of assets upon such dissolution, liquidation or winding up unless proportionate distributive amounts shall be paid on account of the shares of MuniPreferred, ratably, in proportion to the full distributable amounts for which holders of all such parity shares are respectively entitled upon such dissolution, liquidation or winding up.

(d) RIGHTS OF JUNIOR SHARES. Subject to the rights of the holders of shares of any series or class or classes of shares ranking on a parity with the shares of MuniPreferred with respect to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Fund, after payment shall have been made in full to the Holders of the shares of MuniPreferred as provided in paragraph (b) of this Section 12, but not prior thereto, any other series or class or classes of shares ranking junior to the shares of MuniPreferred with respect to the distribution of assets upon dissolution, liquidation or winding up of the affairs of the Fund shall, subject to the respective terms and provisions (if any) applying thereto, be entitled to receive any and all assets remaining to be paid or distributed, and the Holders of the shares of MuniPreferred shall not be entitled to share therein.

(e) CERTAIN EVENTS NOT CONSTITUTING LIQUIDATION. Neither the sale of all or substantially all the property or business of the Fund, nor the merger or consolidation of the Fund into or with any Massachusetts business trust or corporation nor the merger or consolidation of any Massachusetts business trust or corporation into or with the Fund shall be a dissolution, liquidation or winding up, whether voluntary or involuntary, for the purposes of this Section 12.

13. MISCELLANEOUS.

(a) AMENDMENT OF APPENDIX A TO ADD ADDITIONAL SERIES. Subject to the provisions of Section 10 of this Part I, the Board of Trustees may, by resolution duly adopted, without shareholder approval (except as otherwise provided by this Statement or required by applicable law), amend Appendix A hereto to (1) reflect any amendments hereto which the Board of Trustees is entitled to adopt pursuant to the terms of this Statement without shareholder approval or (2) add additional series of MuniPreferred or additional shares of a series of MuniPreferred (and terms relating thereto) to the series and shares of MuniPreferred theretofore described thereon. Each such additional series and all such additional shares shall be governed by the terms of this Statement.

(b) APPENDIX A INCORPORATED BY REFERENCE. Appendix A hereto is incorporated in and made a part of this Statement by reference thereto.

(c) NO FRACTIONAL SHARES. No fractional shares of MuniPreferred shall be issued.

(d) STATUS OF SHARES OF MUNIPREFERRED REDEEMED, EXCHANGED OR OTHERWISE ACQUIRED BY THE FUND. Shares of MuniPreferred which are redeemed, exchanged or otherwise acquired by the Fund shall return to the status of authorized and unissued Preferred Shares without designation as to series.

(e) BOARD MAY RESOLVE AMBIGUITIES. To the extent permitted by applicable law, the Board of Trustees may interpret or adjust the provisions of this Statement to resolve any inconsistency or ambiguity or to remedy any formal defect, and may amend this Statement with respect to any series of MuniPreferred prior to the issuance of shares of such series.

29

(f) HEADINGS NOT DETERMINATIVE. The headings contained in this Statement are for convenience of reference only and shall not affect the meaning or interpretation of this Statement.

(g) NOTICES. All notices or communications, unless otherwise specified in the By-Laws of the Fund or this Statement, shall be sufficiently given if in writing and delivered in person or mailed by first-class mail, postage prepaid.

33

(i) all Hold Orders for shares of such series shall be considered valid, but only up to and including in the aggregate the number of Outstanding shares of such series held by such Existing Holder, and if the number of shares of such series subject to such Hold Orders exceeds the number of Outstanding shares of such series held by such Existing Holder, the number of shares subject to each such Hold Order shall be reduced pro rata to cover the number of Outstanding shares of such series held by such Existing Holder;

(ii) (A) any Bid for shares of such series shall be considered valid up to and including the excess of the number of Outstanding shares of such series held by such Existing Holder over the number of shares of such series subject to any Hold Orders referred to in clause (i) above;

(B) subject to subclause (A), if more than one Bid of an Existing Holder for shares of such series is submitted to the Auction Agent with the same rate and the number of Outstanding shares of such series subject to such Bids is greater than such excess, such Bids shall be considered valid up to and including the amount of such excess, and the number of shares of such series subject to each Bid with the same rate shall be reduced pro rata to cover the number of shares of such series equal to such excess;

(C) subject to subclauses (A) and (B), if more than one Bid of an Existing Holder for shares of such series is submitted to the Auction Agent with different rates, such Bids shall be considered valid in the ascending order of their respective rates up to and including the amount of such excess; and

(D) in any such event, the number, if any, of such Outstanding shares of such series subject to any portion of Bids considered not valid in whole or in part under this clause (ii) shall be treated as the subject of a Bid for shares of such series by or on behalf of a Potential Holder at the rate therein specified; and

(iii) all Sell Orders for shares of such series shall be considered valid up to and including the excess of the number of Outstanding shares of such series held by such Existing Holder over the sum of shares of such series subject to valid Hold Orders referred to in clause (i) above and valid Bids referred to in clause (ii) above.

(e) If more than one Bid for one or more shares of a series of MuniPreferred is submitted to the Auction Agent by or on behalf of any Potential Holder, each such Bid submitted shall be a separate Bid with the rate and number of shares therein specified.

(f) Any Order submitted by a Beneficial Owner or a Potential Beneficial Owner to its Broker-Dealer, or by a Broker-Dealer to the Auction Agent, prior to the Submission Deadline on any Auction Date, shall be irrevocable.

3. DETERMINATION OF SUFFICIENT CLEARING BIDS, WINNING BID RATE AND APPLICABLE RATE.

(a) Not earlier than the Submission Deadline on each Auction Date for shares of a series of MuniPreferred, the Auction Agent shall assemble all valid Orders submitted or deemed submitted to it by the Broker-Dealers in respect of shares of such series (each such Order as submitted or deemed submitted by a Broker-Dealer being hereinafter referred to individually as a "Submitted Hold Order," a "Submitted Bid" or a "Submitted Sell Order," as the case may be, or as a "Submitted Order" and collectively as "Submitted Hold Orders," "Submitted Bids" or "Submitted Sell Orders," as the case may be, or as "Submitted Orders") and shall determine for such series:

34

(i) the excess of the number of Outstanding shares of such series over the number of Outstanding shares of such series subject to Submitted Hold Orders (such excess being hereinafter referred to as the "Available MuniPreferred" of such series);

(ii) from the Submitted Orders for shares of such series whether:

(A) the number of Outstanding shares of such series subject to Submitted Bids of Potential Holders specifying one or more rates equal to or lower than the Maximum Rate for shares of such series;

exceeds or is equal to the sum of:

(B) the number of Outstanding shares of such series subject to Submitted Bids of Existing Holders specifying one or more rates higher than the Maximum Rate for shares of such series; and

(C) the number of Outstanding shares of such series subject to Submitted Sell Orders (in the event such excess or such equality exists (other than because the number of shares of such series in subclauses (B) and (C) above is zero because all of the Outstanding shares of such series are subject to Submitted Hold Orders), such Submitted Bids in subclause (A) above being hereinafter referred to collectively as "Sufficient Clearing Bids" for shares of such series); and

(iii) if Sufficient Clearing Bids for shares of such series exist, the lowest rate specified in such Submitted Bids (the "Winning Bid Rate" for shares of such series) which if:

(A) (I) each such Submitted Bid of Existing Holders specifying such lowest rate and (II) all other such Submitted Bids of Existing Holders specifying lower rates were rejected, thus entitling such Existing Holders to continue to hold the shares of such series that are subject to such Submitted Bids; and

(B) (I) each such Submitted Bid of Potential Holders specifying such lowest rate and (II) all other such Submitted Bids of Potential Holders specifying lower rates were accepted;

would result in such Existing Holders described in subclause (A) above continuing to hold an aggregate number of Outstanding shares of such series which, when added to the number of Outstanding shares of such series to be purchased by such Potential Holders described in subclause (B) above, would equal not less than the Available MuniPreferred of such series.

(b) Promptly after the Auction Agent has made the determinations pursuant to paragraph (a) of this Section 3, the Auction Agent shall advise the Fund of the Maximum Rate for shares of the series of MuniPreferred for which an Auction is being held on the Auction Date and, based on such determination, the Applicable Rate for shares of such series for the next succeeding Rate Period thereof as follows:

(i) if Sufficient Clearing Bids for shares of such series exist, that the Applicable Rate for all shares of such series for the next succeeding Rate Period thereof shall be equal to the Winning Bid Rate for shares of such series so determined;

35

(ii) if Sufficient Clearing Bids for shares of such series do not exist (other than because all of the Outstanding shares of such series are subject to Submitted Hold Orders), that the Applicable Rate for all shares of such series for the next succeeding Rate Period thereof shall be equal to the Maximum Rate for shares of such series; or

(iii) if all of the Outstanding shares of such series are subject to Submitted Hold Orders, that the Applicable Rate for all shares of such series for the next succeeding Rate Period thereof shall be as set forth in Section 12 of Appendix A hereto.

4. ACCEPTANCE AND REJECTION OF SUBMITTED BIDS AND SUBMITTED SELL ORDERS AND ALLOCATION OF SHARES. Existing Holders shall continue to hold the shares of MuniPreferred that are subject to Submitted Hold Orders, and, based on the determinations made pursuant to paragraph (a) of Section 3 of this Part II, the Submitted Bids and Submitted Sell Orders shall be accepted or rejected by the Auction Agent and the Auction Agent shall take such other action as set forth below:

(a) If Sufficient Clearing Bids for shares of a series of MuniPreferred have been made, all Submitted Sell Orders with respect to shares of such series shall be accepted and, subject to the provisions of paragraphs
(d) and (e) of this Section 4, Submitted Bids with respect to shares of such series shall be accepted or rejected as follows in the following order of priority and all other Submitted Bids with respect to shares of such series shall be rejected:

(i) Existing Holders' Submitted Bids for shares of such series specifying any rate that is higher than the Winning Bid Rate for shares of such series shall be accepted, thus requiring each such Existing Holder to sell the shares of MuniPreferred subject to such Submitted Bids;

(ii) Existing Holders' Submitted Bids for shares of such series specifying any rate that is lower than the Winning Bid Rate for shares of such series shall be rejected, thus entitling each such Existing Holder to continue to hold the shares of MuniPreferred subject to such Submitted Bids;

(iii) Potential Holders' Submitted Bids for shares of such series specifying any rate that is lower than the Winning Bid Rate for shares of such series shall be accepted;

(iv) each Existing Holder's Submitted Bid for shares of such series specifying a rate that is equal to the Winning Bid Rate for shares of such series shall be rejected, thus entitling such Existing Holder to continue to hold the shares of MuniPreferred subject to such Submitted Bid, unless the number of Outstanding shares of MuniPreferred subject to all such Submitted Bids shall be greater than the number of shares of MuniPreferred ("remaining shares") in the excess of the Available MuniPreferred of such series over the number of shares of MuniPreferred subject to Submitted Bids described in clauses (ii) and
(iii) of this paragraph (a), in which event such Submitted Bid of such Existing Holder shall be rejected in part, and such Existing Holder shall be entitled to continue to hold shares of MuniPreferred subject to such Submitted Bid, but only in an amount equal to the number of shares of MuniPreferred of such series obtained by multiplying the number of remaining shares by a fraction, the numerator of which shall be the number of Outstanding shares of MuniPreferred held by such Existing Holder subject to such Submitted Bid and the denominator of which shall be the aggregate number of Outstanding shares of MuniPreferred subject to such Submitted Bids made by all such Existing Holders that specified a rate equal to the Winning Bid Rate for shares of such series; and

(v) each Potential Holder's Submitted Bid for shares of such series specifying a rate that is equal to the Winning Bid Rate for shares of such series shall be accepted

36

but only in an amount equal to the number of shares of such series obtained by multiplying the number of shares in the excess of the Available MuniPreferred of such series over the number of shares of MuniPreferred subject to Submitted Bids described in clauses (ii) through (iv) of this paragraph (a) by a fraction, the numerator of which shall be the number of Outstanding shares of MuniPreferred subject to such Submitted Bid and the denominator of which shall be the aggregate number of Outstanding shares of MuniPreferred subject to such Submitted Bids made by all such Potential Holders that specified a rate equal to the Winning Bid Rate for shares of such series.

(b) If Sufficient Clearing Bids for shares of a series of MuniPreferred have not been made (other than because all of the Outstanding shares of such series are subject to Submitted Hold Orders), subject to the provisions of paragraph (d) of this Section 4, Submitted Orders for shares of such series shall be accepted or rejected as follows in the following order of priority and all other Submitted Bids for shares of such series shall be rejected:

(i) Existing Holders' Submitted Bids for shares of such series specifying any rate that is equal to or lower than the Maximum Rate for shares of such series shall be rejected, thus entitling such Existing Holders to continue to hold the shares of MuniPreferred subject to such Submitted Bids;

(ii) Potential Holders' Submitted Bids for shares of such series specifying any rate that is equal to or lower than the Maximum Rate for shares of such series shall be accepted; and

(iii) Each Existing Holder's Submitted Bid for shares of such series specifying any rate that is higher than the Maximum Rate for shares of such series and the Submitted Sell Orders for shares of such series of each Existing Holder shall be accepted, thus entitling each Existing Holder that submitted or on whose behalf was submitted any such Submitted Bid or Submitted Sell Order to sell the shares of such series subject to such Submitted Bid or Submitted Sell Order, but in both cases only in an amount equal to the number of shares of such series obtained by multiplying the number of shares of such series subject to Submitted Bids described in clause (ii) of this paragraph
(b) by a fraction, the numerator of which shall be the number of Outstanding shares of such series held by such Existing Holder subject to such Submitted Bid or Submitted Sell Order and the denominator of which shall be the aggregate number of Outstanding shares of such series subject to all such Submitted Bids and Submitted Sell Orders.

(c) If all of the Outstanding shares of a series of MuniPreferred are subject to Submitted Hold Orders, all Submitted Bids for shares of such series shall be rejected.

(d) If, as a result of the procedures described in clause (iv) or (v) of paragraph (a) or clause (iii) of paragraph (b) of this Section 4, any Existing Holder would be entitled or required to sell, or any Potential Holder would be entitled or required to purchase, a fraction of a share of a series of MuniPreferred on any Auction Date, the Auction Agent shall, in such manner as it shall determine in its sole discretion, round up or down the number of shares of MuniPreferred of such series to be purchased or sold by any Existing Holder or Potential Holder on such Auction Date as a result of such procedures so that the number of shares so purchased or sold by each Existing Holder or Potential Holder on such Auction Date shall be whole shares of MuniPreferred.

(e) If, as a result of the procedures described in clause (v) of paragraph (a) of this Section 4, any Potential Holder would be entitled or required to purchase less than a whole share of a series of MuniPreferred on any Auction Date, the Auction Agent shall, in such manner as it shall

37

determine in its sole discretion, allocate shares of MuniPreferred of such series for purchase among Potential Holders so that only whole shares of MuniPreferred of such series are purchased on such Auction Date as a result of such procedures by any Potential Holder, even if such allocation results in one or more Potential Holders not purchasing shares of MuniPreferred of such series on such Auction Date.

(f) Based on the results of each Auction for shares of a series of MuniPreferred, the Auction Agent shall determine the aggregate number of shares of such series to be purchased and the aggregate number of shares of such series to be sold by Potential Holders and Existing Holders and, with respect to each Potential Holder and Existing Holder, to the extent that such aggregate number of shares to be purchased and such aggregate number of shares to be sold differ, determine to which other Potential Holder(s) or Existing Holder(s) they shall deliver, or from which other Potential Holder(s) or Existing Holder(s) they shall receive, as the case may be, shares of MuniPreferred of such series. Notwithstanding any provision of the Auction Procedures or the Settlement Procedures to the contrary, in the event an Existing Holder or Beneficial Owner of shares of a series of MuniPreferred with respect to whom a Broker-Dealer submitted a Bid to the Auction Agent for such shares that was accepted in whole or in part, or submitted or is deemed to have submitted a Sell Order for such shares that was accepted in whole or in part, fails to instruct its Agent Member to deliver such shares against payment therefor, partial deliveries of shares of MuniPreferred that have been made in respect of Potential Holders' or Potential Beneficial Owners' Submitted Bids for shares of such series that have been accepted in whole or in part shall constitute good delivery to such Potential Holders and Potential Beneficial Owners.

(g) Neither the Fund nor the Auction Agent nor any affiliate of either shall have any responsibility or liability with respect to the failure of an Existing Holder, a Potential Holder, a Beneficial Owner, a Potential Beneficial Owner or its respective Agent Member to deliver shares of MuniPreferred of any series or to pay for shares of MuniPreferred of any series sold or purchased pursuant to the Auction Procedures or otherwise.

5. NOTIFICATION OF ALLOCATIONS. Whenever the Fund intends to include any net capital gains or other income taxable for Federal income tax purposes in any dividend on shares of MuniPreferred, the Fund shall, in the case of a Minimum Rate Period or a Special Rate Period of 28 Rate Period Days or fewer, and may, in the case of any other Special Rate Period, notify the Auction Agent of the amount to be so included not later than the Dividend Payment Date next preceding the Auction Date on which the Applicable Rate for such dividend is to be established. Whenever the Auction Agent receives such notice from the Fund, it will be required in turn to notify each Broker-Dealer, who, on or prior to such Auction Date, in accordance with its Broker-Dealer Agreement, will be required to notify its Beneficial Owners and Potential Beneficial Owners of shares of MuniPreferred believed by it to be interested in submitting an Order in the Auction to be held on such Auction Date.

6. AUCTION AGENT. For so long as any shares of MuniPreferred are outstanding, the Auction Agent, duly appointed by the Fund to so act, shall be in each case a commercial bank, trust company or other financial institution independent of the Fund and its affiliates (which however, may engage or have engaged in business transactions with the Fund or its affiliates) and at no time shall the Fund or any of its affiliates act as the Auction Agent in connection with the Auction Procedures. If the Auction Agent resigns or for any reason its appointment is terminated during any period that any shares of MuniPreferred are outstanding, the Board of Trustees shall use its best efforts promptly thereafter to appoint another qualified commercial bank, trust company or financial institution to act as the Auction Agent. The Auction Agent's registry of Existing Holders of shares of a series of MuniPreferred shall be conclusive and binding on the Broker-Dealers. A Broker-Dealer may inquire of the Auction Agent between 3:00 p.m. on the Business Day preceding an Auction for shares of a series of MuniPreferred and 9:30 a.m. on the Auction Date for such Auction to ascertain the number of shares of such series in respect of which the Auction Agent has determined such Broker-Dealer to be an Existing Holder. If such Broker-Dealer

38

believes it is the Existing Holder of fewer shares of such series than specified by the Auction Agent in response to such Broker-Dealer's inquiry, such Broker-Dealer may so inform the Auction Agent of that belief. Such Broker-Dealer shall not, in its capacity as Existing Holder of shares of such series, submit Orders in such Auction in respect of shares of such series covering in the aggregate more than the number of shares of such series specified by the Auction Agent in response to such Broker-Dealer's inquiry.

7. TRANSFER OF SHARES OF MUNIPREFERRED. Unless otherwise permitted by the Fund, a Beneficial Owner or an Existing Holder may sell, transfer or otherwise dispose of shares of MuniPreferred only in whole shares and only pursuant to a Bid or Sell Order placed with the Auction Agent in accordance with the procedures described in this Part II or to a Broker-Dealer, provided, however, that (a) 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 as the holder of such shares to that Broker-Dealer or another customer of that Broker-Dealer shall not be deemed to be a sale, transfer or other disposition for purposes of this Section 7 if such Broker-Dealer remains the Existing Holder of the shares so sold, transferred or disposed of immediately after such sale, transfer or disposition and (b) in the case of all transfers other than pursuant to Auctions, the Broker-Dealer (or other Person, if permitted by the Fund) to whom such transfer is made shall advise the Auction Agent of such transfer.

8. GLOBAL CERTIFICATE. Prior to the commencement of a Voting Period,
(i) all of the shares of a series of MuniPreferred outstanding from time to time shall be represented by one global certificate registered in the name of the Securities Depository or its nominee and (ii) no registration of transfer of shares of a series of MuniPreferred shall be made on the books of the Fund to any Person other than the Securities Depository or its nominee.

"ESCROWED BONDS" shall have the meaning set forth in the Rating Agency Guidelines.

"GROSS-UP PAYMENT" means payment to a Holder of shares of MuniPreferred of an amount which, when taken together with the aggregate amount of Taxable Allocations made to such Holder to which such Gross-up Payment relates, would cause such Holder's dividends in dollars (after Federal income tax consequences) from the aggregate of such Taxable Allocations and the related Gross-up Payment to be equal to the dollar amount of the dividends which would have been received by such Holder if the amount of such aggregate Taxable Allocations would have been excludable from the gross income of such Holder. Such Gross-up Payment shall be calculated (i) without consideration being given to the time value of money; (ii) assuming that no Holder of shares of MuniPreferred is subject to the Federal alternative minimum tax with respect to dividends received from the Fund; and (iii) assuming that each Taxable Allocation and each Gross-up Payment (except to the extent such Gross-up Payment is designated as an exempt-interest dividend under Section 852(b)(5) of the Code or successor provisions) would be taxable in the hands of each Holder of shares of MuniPreferred at the maximum marginal regular Federal individual income tax rate applicable to ordinary income or net capital gains, as applicable, or the maximum marginal regular Federal corporate income tax rate applicable to ordinary income or net capital gains, as applicable, whichever is greater, in effect at the time such Gross-up Payment is made.

"INVERSE FLOATER" shall have the meaning set forth in the Rating Agency Guidelines.

       PREVAILING RATING           PERCENTAGE
       ----------------            ----------

provided, however, that in the event the Fund has notified the Auction Agent of its intent to allocate income taxable for Federal income tax purposes to shares of such series prior to the Auction establishing the Applicable Rate for shares of such series, the applicable percentage in the foregoing table shall be divided by the quantity 1 minus the maximum marginal combined regular Federal personal income tax rate applicable to ordinary income (taking into account the Federal income tax deductibility of state and local taxes paid or incurred) or the maximum marginal regular Federal corporate income tax rate applicable to ordinary income, whichever is greater.

For purposes of this definition, the "prevailing rating" of shares of a series of MuniPreferred shall be (i) "aa3"/AA-- or higher if such shares have a rating of "aa3" or better by Moody's and AA-- or better by S&P or the equivalent of such ratings by such agencies or a substitute rating agency or substitute rating agencies selected as provided below, (ii) if not "aa3"/AA-- or higher, then "a3"/A-- if such shares have a rating of "a3" or better by Moody's and A-- or better by S&P or the equivalent of such ratings by such agencies or a substitute rating agency or substitute rating agencies selected as provided below, (iii) if not "aa3"/AA-- or higher or "a3"/A--, then "baa3"/BBB-- if such shares have a

The Fund shall take all reasonable action necessary to enable either S&P or Moody's to provide a rating for shares of MuniPreferred. If neither S&P nor Moody's shall make such a rating available, the party set forth in Section 7 of Appendix A or its successor shall select at least one nationally recognized statistical rating organization (as that term is used in the rules and regulations of the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended from time to time) to act as a substitute rating agency in respect of shares of the series of MuniPreferred set forth opposite such party's name in Section 7 of Appendix A and the Fund shall take all reasonable action to enable such rating agency to provide a rating for such shares.

For purposes of subparagraph (b)(iii) of Section 3 of Part II of this Statement, the Applicable Rate for shares of such series for the next succeeding Rate Period of shares of such series shall be equal to the lesser of the Kenny Index (if such Rate Period consists of fewer than 183 Rate Period Days) or the product of (A)(I) the "AA" Composite Commercial Paper Rate on such Auction Date for such Rate Period, if such Rate Period consists of fewer than 183 Rate Period Days; (II) the Treasury Bill Rate on such Auction Date for such Rate Period, if such Rate Period consists of more than 182 but fewer than 365 Rate Period Days; or (III) the Treasury Note Rate on such Auction Date for such Rate Period, if such Rate Period is more than 364 Rate Period Days (the rate described in the foregoing clause (A)(I), (II) or
(III), as applicable, being referred to herein as the "Benchmark Rate") and (B) 1 minus the maximum marginal combined regular Federal personal income tax rate applicable to ordinary income (taking into account the Federal income tax deductibility of state and local taxes paid or incurred) or the maximum marginal regular Federal corporate income tax rate applicable to ordinary income, whichever is greater; provided, however, that if the Fund has notified the Auction Agent of its intent to allocate to shares of such series in such Rate Period any net capital gains or other income taxable for Federal income tax purposes ("Taxable Income"), the Applicable Rate for shares of such series for such Rate Period will be (i) if the Taxable Yield Rate (as defined below) is greater than the Benchmark Rate, then the Benchmark Rate, or (ii) if the Taxable Yield Rate is less than or equal to the Benchmark Rate, then the rate equal to the sum of (x) the lesser of the Kenny Index (if such Rate Period consists of fewer than 183 Rate Period Days) or the product of the Benchmark Rate multiplied by the factor set forth in the preceding clause (B) and (y) the product of the maximum marginal combined regular Federal personal income tax rate applicable to ordinary income (taking into account the Federal income tax deductibility of state and local taxes paid or incurred) or the maximum marginal regular Federal corporate income tax applicable to ordinary income, whichever is greater, multiplied by the Taxable Yield Rate. For purposes of the foregoing, Taxable Yield Rate means the rate determined by (a) dividing the amount of Taxable Income available for distribution per such share of MuniPreferred by the number of days in the Dividend Period in respect of which such Taxable Income is contemplated to be distributed, (b) multiplying the amount determined in (a) above by 365 (in the case of a Dividend Period of 7 Rate Period Days) or 360 (in the case of any other Dividend Period), and (c) dividing the amount determined in (b) above by $25,000.

APPENDIX B

RATINGS OF INVESTMENTS

STANDARD & POOR'S CORPORATION--A brief description of the applicable Standard & Poor's Corporation, a division of The McGraw-Hill Companies ("Standard & Poor's" or "S&P") rating symbols and their meanings (as published by S&P) follows:

A Standard & Poor's issue credit rating is a current opinion of the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program. It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation. The issue credit rating is not a recommendation to purchase, sell, or hold a financial obligation, inasmuch as it does not comment as to market price or suitability for a particular investor.

Issue credit ratings are based on current information furnished by the obligors or obtained by Standard & Poor's from other sources it considers reliable. Standard & Poor's does not perform an audit in connection with any credit rating and may, on occasion, rely on unaudited financial information. Credit ratings may be changed, suspended, or withdrawn as a result of changes in, or unavailability of, such information, or based on other circumstances.

Issue credit ratings can be either long-term or short-term. Short-term ratings are generally assigned to those obligations considered short-term in the relevant market. In the U.S., for example, that means obligations with an original maturity of no more than 365 days - including commercial paper. Short-term ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. The result is a dual rating, in which the short-term ratings address the put feature, in addition to the usual long-term rating. Medium-term notes are assigned long-term ratings.

LONG-TERM ISSUE CREDIT RATINGS

Issue credit ratings are based in varying degrees, on the following considerations:

1. Likelihood of payment - capacity and willingness of the obligor to meet its financial commitment on an obligation in accordance with the terms of the obligation;

2. Nature of and provisions of the obligation; and

3. Protection afforded by, and relative position of, the obligation in the event of bankruptcy, reorganization, or other arrangement under the laws of bankruptcy and other laws affecting creditors' rights.

The issue ratings definitions are expressed in terms of default risk. As such, they pertain to senior obligations of an entity. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above.

AAA                         An obligation rated "AAA" has the highest rating
                            assigned by Standard & Poor's. The obligor's
                            capacity to meet its financial commitment on the
                            obligation is extremely strong.

AA                          An obligation rated "AA" differs from the
                            highest-rated obligations only in small degree. The
                            obligor's capacity to meet its financial commitment
                            on the obligation is very strong.

B-1

A                           An obligation rated "A" is somewhat more susceptible
                            to the adverse effects of changes in circumstances
                            and economic conditions than obligations in
                            higher-rated categories. However, the obligor's
                            capacity to meet its financial commitment on the
                            obligation is still strong.

BBB                         An obligation rated "BBB" exhibits adequate
                            protection parameters. However, adverse economic
                            conditions or changing circumstances are more likely
                            to lead to a weakened capacity of the obligor to
                            meet its financial commitment on the obligation.

BB, B, CCC, CC, and C       Obligations rated "BB", "B", "CCC", "CC", and "C"
                            are regarded as having significant speculative
                            characteristics. "BB" indicates the least degree of
                            speculation and "C" the highest. While such
                            obligations will likely have some quality and
                            protective characteristics, these may be outweighed
                            by large uncertainties or major exposures to adverse
                            conditions.

BB                          An obligation rated "BB" is less vulnerable to
                            nonpayment than other speculative issues. However,
                            it faces major ongoing uncertainties or exposure to
                            adverse business, financial, or economic conditions,
                            which could lead to the obligor's inadequate
                            capacity to meet its financial commitment on the
                            obligation.

B                           An obligation rated "B" is more vulnerable to
                            nonpayment than obligations rated "BB", but the
                            obligor currently has the capacity to meet its
                            financial commitment on the obligation. Adverse
                            business, financial, or economic conditions will
                            likely impair the obligor's capacity or willingness
                            to meet its financial commitment on the obligation.

CCC                         An obligation rated "CCC" is currently vulnerable to
                            nonpayment and is dependent upon favorable business,
                            financial, and economic conditions for the obligor
                            to meet its financial commitment on the obligation.
                            In the event of adverse business, financial, or
                            economic conditions, the obligor is not likely to
                            have the capacity to meet its financial commitment
                            on the obligation.

CC                          An obligation rated "CC" is currently highly
                            vulnerable to nonpayment.

C                           The "C" rating may be used to cover a situation
                            where a bankruptcy petition has been filed or
                            similar action has been taken, but payments on this
                            obligation are being continued.

D                           An obligation rated "D" is in payment default. The
                            "D" rating category is used when payments on an
                            obligation are not made on the date due even if the
                            applicable grace period has not expired, unless
                            Standard & Poor's believes that such payments will
                            be made during such grace period. The "D" rating
                            also will be used upon the filing of a bankruptcy
                            petition or the taking of a similar action if
                            payments on an obligation are jeopardized.

Plus (+) or minus (-) The ratings from `AA' to `CCC' may be modified by the addition of a plus or minus sign to show relative standing within the major rating categories.

B-2

c                           The `c' subscript is used to provide additional
                            information to investors that the bank may terminate
                            its obligation to purchase tendered bonds if the
                            long-term credit rating of the issuer is below an
                            investment-grade level and/or the issuer's bonds are
                            deemed taxable.

P                           The letter `p' indicates that the rating is
                            provisional. A provisional rating assumes the
                            successful completion of the project financed by the
                            debt being rated and indicates that payment of debt
                            service requirements is largely or entirely
                            dependent upon the successful, timely completion of
                            the project. This rating, however, while addressing
                            credit quality subsequent to completion of the
                            project, makes no comment on the likelihood of or
                            the risk of default upon failure of such completion.
                            The investor should exercise his own judgment with
                            respect to such likelihood and risk.

*                           Continuance of the ratings is contingent upon
                            Standard & Poor's receipt of an executed copy of the
                            escrow agreement or closing documentation confirming
                            investments and cash flows.

r                           The `r' highlights derivative, hybrid, and certain
                            other obligations that Standard & Poor's believes
                            may experience high volatility or high variability
                            in expected returns as a result of noncredit risks.
                            Examples of such obligations are securities with
                            principal or interest return indexed to equities,
                            commodities, or currencies; certain swaps and
                            options; and interest-only and principal-only
                            mortgage securities. The absence of an `r' symbol
                            should not be taken as an indication that an
                            obligation will exhibit no volatility or variability
                            in total return.

N.R.                        Not rated.

         Debt obligations of issuers outside the United States and its

territories are rated on the same basis as domestic corporate and municipal issues. The ratings measure the creditworthiness of the obligor but do not take into account currency exchange and related uncertainties.

Bond Investment Quality Standards Under present commercial bank regulations issued by the Comptroller of the Currency, bonds rated in the top four categories ( `AAA', `AA', `A', `BBB', commonly known as investment-grade ratings) generally are regarded as eligible for bank investment. Also, the laws of various states governing legal investments impose certain rating or other standards for obligations eligible for investment by savings banks, trust companies, insurance companies, and fiduciaries in general.

SHORT-TERM ISSUE CREDIT RATINGS

NOTES

A Standard & Poor's note ratings reflects the liquidity factors and market access risks unique to notes. Notes due in three years or less will likely receive a note rating. Notes maturing beyond three years will most likely receive a long-term debt rating. The following criteria will be used in making that assessment:

o Amortization schedule -- the larger the final maturity relative to other maturities, the more likely it will be treated as a note; and

B-3

o Source of payment -- the more dependent the issue is on the market for its refinancing, the more likely it will be treated as a note.

Note rating symbols are as follows:

SP-1 Strong capacity to pay principal and interest. An issue determined to possess a very strong capacity to pay debt service is given a plus (+) designation.

SP-2 Satisfactory capacity to pay principal and interest, with some vulnerability to adverse financial and economic changes over the term of the notes.

SP-3 Speculative capacity to pay principal and interest.

A note rating is not a recommendation to purchase, sell, or hold a security inasmuch as it does not comment as to market price or suitability for a particular investor. The ratings are based on current information furnished to S&P by the issuer or obtained by S&P from other sources it considers reliable. S&P does not perform an audit in connection with any rating and may, on occasion, rely on unaudited financial information. The ratings may be changed, suspended, or withdrawn as a result of changes in or unavailability of such information or based on other circumstances.

COMMERCIAL PAPER

An S&P commercial paper rating is a current assessment of the likelihood of timely payment of debt having an original maturity of no more than 365 days.

Ratings are graded into several categories, ranging from `A' for the highest quality obligations to `D' for the lowest. These categories are as follows:

A-1      The A-1 designation indicates that the degree of safety
         regarding timely payment is strong. Those issues determined to
         possess extremely strong safety characteristics are denoted
         with a plus sign (+) designation.

A-2      Capacity for timely payment on issues with the designation A-2
         is satisfactory. However, the relative degree of safety is not
         as high as for issues designated A-1.

A-3      Issues with the A-3 designation have adequate capacity for
         timely payment. They are, however, more vulnerable to the
         adverse effects of changes in circumstances than obligations
         carrying the higher designations.

B        Issues rated `B' are regarded as having only speculative
         capacity for timely payment.

C        This rating is assigned to short-term debt obligations with a
         doubtful capacity for payment.

D        Debt rated `D' is in payment default. The `D' rating category
         is used when interest payments of principal payments are not
         made on the date due, even if the applicable grace period has
         not expired, unless Standard & Poor's believes such payments
         will be made during such grace period.

A commercial rating is not a recommendation to purchase, sell, or hold a security inasmuch as it does not comment as to market price or suitability for a particular investor. The ratings are based on current information furnished to S&P by the issuer or obtained by S&P from other sources it considers reliable. S&P does not perform an audit in connection with any rating and may, on occasion, rely on

B-4

unaudited financial information. The ratings may be changed, suspended, or withdrawn as a result of changes in or unavailability of such information or based on other circumstances.

MOODY'S INVESTORS SERVICE, INC.--A brief description of the applicable Moody's Investors Service, Inc. ("Moody's") rating symbols and their meanings (as published by Moody's) follows:

MUNICIPAL BONDS

Aaa      Bonds which are rated `Aaa' are judged to be of the best
         quality. They carry the smallest degree of investment risk and
         are generally referred to as "gilt edged." Interest payments
         are protected by a large or by an exceptionally stable margin
         and principal is secure. While the various protective elements
         are likely to change, such changes as can be visualized are
         most unlikely to impair the fundamentally strong position of
         such issues.

Aa       Bonds which are rated `Aa' are judged to be of high quality by
         all standards. Together with the `Aaa' group they comprise
         what are generally known as high grade bonds. They are rated
         lower than the best bonds because margins of protection may
         not be as large as in `Aaa' securities or fluctuation of
         protective elements may be of greater amplitude or there may
         be other elements present which make the long-term risks
         appear somewhat larger than in `Aaa' securities.

A        Bonds which are rated `A' possess many favorable investment
         attributes and are to be considered as upper medium grade
         obligations. Factors giving security to principal and interest
         are considered adequate, but elements may be present that
         suggest a susceptibility to impairment sometime in the future.

Baa      Bonds which are rated `Baa' are considered as medium grade
         obligations, i.e., they are neither highly protected nor
         poorly secured. Interest payments and principal security
         appear adequate for the present but certain protective
         elements may be lacking or may be characteristically
         unreliable over any great length of time. Such bonds lack
         outstanding investment characteristics and in fact have
         speculative characteristics as well.

Ba       Bonds which are rated `Ba' are judged to have speculative
         elements; their future cannot be considered as well assured.
         Often the protection of interest and principal payments may be
         very moderate and thereby not well safeguarded during both
         good and bad times over the future. Uncertainty of position
         characterizes bonds in this class.

B        Bonds which are rated `B' generally lack characteristics of
         the desirable investment. Assurance of interest and principal
         payments or of maintenance of other terms of the contract over
         any long period of time may be small.

Caa      Bonds which are rated `Caa' are of poor standing. Such issues
         may be in default or there may be present elements of danger
         with respect to principal or interest.

Ca       Bonds which are rated `Ca' represent obligations which are
         speculative in a high degree. Such issues are often in default
         or have other marked shortcomings.

C        Bonds which are rated `C' are the lowest rated class of bonds,
         and issues so rated can be regarded as having extremely poor
         prospects of ever attaining any real investment standing.

B-5

Issues that are secured by escrowed funds held in trust, reinvested in direct, non-callable U.S. government obligations or non-callable obligations unconditionally guaranteed by the U.S. Government or Resolution Funding Corporation are identified with a # (hatchmark) symbol, e.g., #Aaa.

Con. (...): Bonds for which the security depends upon the completion of some act or the fulfillment of some condition are rated conditionally. These are bonds secured by (a) earnings of projects under construction, (b) earnings of projects unseasoned in operation experience, (c) rentals which begin when facilities are completed, or (d) payments to which some other limiting condition attaches. The parenthetical rating denotes probable credit stature upon completion of construction or elimination of the basis of the condition.

Note: Moody's applies numerical modifiers 1, 2 and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

SHORT-TERM LOANS

MIG 1/VMIG 1          This designation denotes superior credit quality.
                      Excellent protection is afforded by established
                      cash flows, highly reliable liquidity support, or
                      demonstrated broad-based access to the market for
                      refinancing.

MIG 2/VMIG 2          This designation denotes strong credit quality.
                      Margins of protection are ample, although not as
                      large as in the preceding group.

MIG 3/VMIG 3          This designation denotes acceptable credit
                      quality. Liquidity and cash-flow protection may
                      be narrow, and market access for refinancing is
                      likely to be less well-established.

SG                    This designation denotes speculative-grade credit
                      quality. Debt instruments in this category may
                      lack sufficient margins of protection.

SHORT-TERM DEBT RATINGS

Issuers rated Prime-1 (or supporting institutions) have a superior ability for repayment of senior short-term debt obligations. Prime-1 repayment ability will normally be evidenced by the following characteristics:

-- Leading market positions in well-established industries.

-- High rates of return on funds employed.

-- Conservative capitalization structures with moderate reliance on debt and ample asset protection.

-- Broad margins in earnings coverage of fixed financial charges and high internal cash generation.

-- Well-established access to a range of financial markets and assured sources of alternate liquidity.

Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above

B-6

but to a lesser degree. Earnings trends and coverage ratios, while sound, will be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

Issuers rated Prime-3 (or supporting institutions) have an acceptable ability for repayment of senior short-term debt obligations. The effect of industry characteristics and market composition may be more pronounced. Variability in earnings and profitability may result in changes in the level of debt protection measurements and the requirement for relatively high financial leverage.

FITCH RATINGS--A brief description of the applicable Fitch Ratings ("Fitch") ratings symbols and meanings (as published by Fitch) follows:

LONG-TERM CREDIT RATINGS

INVESTMENT GRADE

         AAA      Highest credit quality. `AAA' ratings denote the lowest
                  expectation of credit risk. They are assigned only in case of
                  exceptionally strong capacity for timely payment of financial
                  commitments. This capacity is highly unlikely to be adversely
                  affected by foreseeable events.

         AA       Very high credit quality. `AA' ratings denote a very low
                  expectation of credit risk. They indicate very strong capacity
                  for timely payment of financial commitments. This capacity is
                  not significantly vulnerable to foreseeable events.

         A        High credit quality. `A' ratings denote a low expectation of
                  credit risk. The capacity for timely payment of financial
                  commitments is considered strong. This capacity may,
                  nevertheless, be more vulnerable to changes in circumstances
                  or in economic conditions than is the case for higher ratings.

         BBB      Good credit quality. `BBB' ratings indicate that there is
                  currently a low expectation of credit risk. The capacity for
                  timely payment of financial commitments is considered
                  adequate, but adverse changes in circumstances and in economic
                  conditions are more likely to impair this capacity. This is
                  the lowest investment-grade category.

SPECULATIVE GRADE

         BB       Speculative. `BB' ratings indicate that there is a possibility
                  of credit risk developing, particularly as the result of
                  adverse economic change over time; however, business or
                  financial alternatives may be available to allow financial
                  commitments to be met. Securities rated in this category are
                  not investment grade.

         B        Highly speculative. `B' ratings indicate that significant
                  credit risk is present, but a limited margin of safety
                  remains. Financial commitments are currently being met;
                  however, capacity for continued payment is contingent upon a
                  sustained, favorable business and economic environment.

CCC, CC, C High default risk. Default is a real possibility.
Capacity for meeting financial commitments is solely reliant upon sustained, favorable business or economic

B-7

developments. A `CC' rating indicates that default of some kind appears probable. `C' ratings signal imminent default.

DDD, DD, and D Default. The ratings of obligations in this category are based on their prospects for achieving partial or full recovery in a reorganization or liquidation of the obligor. While expected recovery values are highly speculative and cannot be estimated with any precision, the following serve as general guidelines. `DDD' obligations have the highest potential for recovery, around 90%-100% of outstanding amounts and accrued interest. `DD' indicates potential recoveries in the range of 50%-90%, and `D' the lowest recovery potential,
i.e., below 50%. Entities rated in this category have defaulted on some or all of their obligations. Entities rated `DDD' have the highest prospect for resumption of performance or continued operation with or without a formal reorganization process. Entities rated `DD' and `D' are generally undergoing a formal reorganization or liquidation process; those rated `DD' are likely to satisfy a higher portion of their outstanding obligations, while entities rated `D' have a poor prospect for repaying all obligations.

SHORT-TERM CREDIT RATINGS

A short-term rating has a time horizon of less than 12 months for most obligations, or up to three years for U.S. public finance securities, and thus places greater emphasis on the liquidity necessary to meet financial commitments in a timely manner.

F1       Highest credit quality. Indicates the strongest capacity for
         timely payment of financial commitments; may have an added "+"
         to denote any exceptionally strong credit feature.

F2       Good credit quality. A satisfactory capacity for timely
         payment of financial commitments, but the margin of safety is
         not as great as in the case of the higher ratings.

F3       Fair credit quality. The capacity for timely payment of
         financial commitments is adequate; however, near-term adverse
         changes could result in a reduction to non-investment grade.

B        Speculative. Minimal capacity for timely payment of financial
         commitments, plus vulnerability to near-term adverse changes
         in financial and economic conditions.

C        High default risk. Default is a real possibility. Capacity for
         meeting financial commitments is solely reliant upon a
         sustained, favorable business and economic environment.

D        Default.  Denotes actual or imminent payment default.

Notes:

"+" or "-" may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the `AAA' long-term rating category, to categories below `CCC', or to short-term ratings other than `F1'.

`NR' indicates that Fitch does not rate the issuer or issue in question.

`Withdrawn': A rating is withdrawn when Fitch deems the amount of information available to be inadequate for rating purposes, or when an obligation matures, is called, or refinanced.

B-8

Rating Watch: Ratings are placed on Rating Watch to notify investors that there is a reasonable probability of a rating change and the likely direction of such change. These are designated as "Positive", indicating a potential upgrade, "Negative", for a potential downgrade, or "Evolving", if ratings may be raised, lowered or maintained. Rating Watch is typically resolved over a relatively short period.

A Rating Outlook indicates the direction a rating is likely to move over a one to two year period. Outlooks may be positive, stable, or negative. A positive or negative Rating Outlook does not imply a rating change is inevitable. Similarly, ratings for which outlooks are `stable' could be upgraded or downgraded before an outlook moves to positive or negative if circumstances warrant such an action. Occasionally, Fitch may be unable to identify the fundamental trend and in these cases, the Rating Outlook may be described as `evolving'.

APPENDIX C

HEDGING STRATEGIES AND RISKS

Set forth below is additional information regarding the various defensive hedging techniques.

FUTURES AND INDEX TRANSACTIONS

FINANCIAL FUTURES

A financial future is an agreement between two parties to buy and sell a security for a set price on a future date. They have been designed by boards of trade which have been designated "contracts markets" by the Commodity Futures Trading Commission ("CFTC").

The purchase of financial futures is for the purpose of hedging the Fund's existing or anticipated holdings of long-term debt securities. When the Fund purchases a financial future, it deposits in cash or securities an "initial margin" of between 1% and 5% of the contract amount. Thereafter, the Fund's account is either credited or debited on a daily basis in correlation with the fluctuation in price of the underlying future or other requirements imposed by the exchange in order to maintain an orderly market. The Fund must make additional payments to cover debits to its account and has the right to withdraw credits in excess of the liquidity, the Fund may close out its position at any time prior to expiration of the financial future by taking an opposite position. At closing a final determination of debits and credits is made, additional cash is paid by or to the Fund to settle the final determination and the Fund realizes a loss or gain depending on whether on a net basis it made or received such payments.

The sale of financial futures is for the purpose of hedging the Fund's existing or anticipated holdings of long-term debt securities. For example, if the Fund owns long-term bonds and interest rates were expected to increase, it might sell financial futures. If interest rates did increase, the value of long-term bonds in the Fund's portfolio would decline, but the value of the Fund's financial futures would be expected to increase at approximately the same rate thereby keeping the net asset value of the Fund from declining as much as it otherwise would have.

Among the risks associated with the use of financial futures by the Fund as a hedging device, perhaps the most significant is the imperfect correlation between movements in the price of the financial futures and movements in the price of the debt securities which are the subject of the hedge.

Thus, if the price of the financial future moves less or more than the price of the securities which are the subject of the hedge, the hedge will not be fully effective. To compensate for this imperfect correlation, the Fund may enter into financial futures in a greater dollar amount than the dollar amount of the securities being hedged if the historical volatility of the prices of such securities has been greater than the historical volatility of the financial futures. Conversely, the Fund may enter into fewer financial futures if the historical volatility of the price of the securities being hedged is less than the historical volatility of the financial futures.

The market prices of financial futures may also be affected by factors other than interest rates. One of these factors is the possibility that rapid changes in the volume of closing transactions, whether due to volatile markets or movements by speculators, would temporarily distort the normal relationship between the markets in the financial future and the chosen debt securities. In these circumstances as well as in periods of rapid and large price movements. The Fund might find it difficult or impossible to close out a particular transaction.

C-1

OPTIONS ON FINANCIAL FUTURES

The Fund may also purchase put or call options on financial futures which are traded on a U.S. Exchange or board of trade and enter into closing transactions with respect to such options to terminate an existing position. Currently, options can be purchased with respect to financial futures on U.S. Treasury Bonds on The Chicago Board of Trade. The purchase of put options on financial futures is analogous to the purchase of put options by the Fund on its portfolio securities to hedge against the risk of rising interest rates. As with options on debt securities, the holder of an option may terminate his position by selling an option of the Fund. There is no guarantee that such closing transactions can be effected.

INDEX CONTRACTS

INDEX FUTURES

A tax-exempt bond index which assigns relative values to the tax-exempt bonds included in the index is traded on the Chicago Board of Trade. The index fluctuates with changes in the market values of all tax-exempt bonds included rather than a single bond. An index future is a bilateral agreement pursuant to which two parties agree to take or make delivery of an amount of cash-rather than any security-equal to a specified dollar amount times the difference between the index value at the close of the last trading day of the contract and the price at which the index future was originally written. Thus, an index future is similar to traditional financial futures except that settlement is made in cash.

INDEX OPTIONS

The Fund may also purchase put or call options on U.S. Government or tax- exempt bond index futures and enter into closing transactions with respect to such options to terminate an existing position. Options on index futures are similar to options on debt instruments except that an option on an index future gives the purchaser the right, in return for the premium paid, to assume a position in an index contract rather than an underlying security at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance of the writer's futures margin account which represents the amount by which the market price of the index futures contract, at exercise, is less than the exercise price of the option on the index future.

Bond index futures and options transactions would be subject to risks similar to transactions in financial futures and options thereon as described above. No series will enter into transactions in index or financial futures or related options unless and until, in the Adviser's opinion, the market for such instruments has developed sufficiently.

ITEM 29: INDEMNIFICATION

Section 4 of Article XII of the Registrant's Declaration of Trust provides as follows:

Subject to the exceptions and limitations contained in this Section 4, every person who is, or has been, a Trustee, officer, employee or agent of the Trust, including persons who serve at the request of the Trust as directors, trustees, officers, employees or agents of another organization in which the Trust has an interest as a shareholder, creditor or otherwise (hereinafter referred to as a "Covered Person"), shall be indemnified by the Trust to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been such a Trustee, director, officer, employee or agent and against amounts paid or incurred by him in settlement thereof.

C-3

No indemnification shall be provided hereunder to a Covered Person:

(a) against any liability to the Trust or its Shareholders by reason of a final adjudication by the court or other body before which the proceeding was brought that he engaged in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office;

(b) with respect to any matter as to which he shall have been finally adjudicated not to have acted in good faith in the reasonable belief that his action was in the best interests of the Trust; or

(c) in the event of a settlement or other disposition not involving a final adjudication (as provided in paragraph (a) or (b)) and resulting in a payment by a Covered Person, unless there has been either a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his office by the court or other body approving the settlement or other disposition or a reasonable determination, based on a review of readily available facts (as opposed to a full trial-type inquiry), that he did not engage in such conduct:

(i) by a vote of a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter); or

(ii) by written opinion of independent legal counsel.

The rights of indemnification herein provided may be insured against by policies maintained by the Trust, shall be severable, shall not affect any other rights to which any Covered Person may now or hereafter be entitled, shall continue as to a person who has ceased to be such a Covered Person and shall inure to the benefit of the heirs, executors and administrators of such a person. Nothing contained herein shall affect any rights to indemnification to which Trust personnel other than Covered Persons may be entitled by contract or otherwise under law.

Expenses of preparation and presentation of a defense to any claim, action, suit or proceeding subject to a claim for indemnification under this
Section 4 shall be advanced by the

Trust prior to final disposition thereof upon receipt of an undertaking by or on behalf of the recipient to repay such amount if it is ultimately determined that he is not entitled to indemnification under this Section 4, provided that either:

(a) such undertaking is secured by a surety bond or some other appropriate security or the Trust shall be insured against losses arising out of any such advances; or

(b) a majority of the Disinterested Trustees acting on the matter (provided that a majority of the Disinterested Trustees then in office act on the matter) or independent legal counsel in a written opinion shall determine, based upon a review of the readily available facts (as opposed to a full trial-type inquiry), that there is reason to believe that the recipient ultimately will be found entitled to indemnification.

As used in this Section 4, a "Disinterested Trustee" is one (x) who is not an Interested Person of the Trust (including anyone, as such Disinterested Trustee, who has been exempted from being an Interested Person by any rule, regulation or order of the Commission), and (y) against whom none of such

C-4

actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending.

As used in this Section 4, the words "claim," "action," "suit" or "proceeding" shall apply to all claims, actions, suits, proceedings (civil, criminal, administrative or other, including appeals), actual or threatened; and the words "liability" and "expenses" shall include without limitation, attorneys' fees, costs, judgments, amounts paid in settlement, fines, penalties and other liabilities.

The trustees and officers of the Registrant are covered by Investment Trust Directors and Officers and Errors and Omission policies in the aggregate amount of $50,000,000 against liability and expenses of claims of wrongful acts arising out of their position with the Registrant, except for matters which involve willful acts, bad faith, gross negligence and willful disregard of duty (i.e., where the insured did not act in good faith for a purpose he or she reasonably believed to be in the best interest of Registrant or where he or she had reasonable cause to believe this conduct was unlawful). The policy has a $500,000 deductible, which does not apply to individual trustees or officers.

Section 8 of the Form of Underwriting Agreement filed as Exhibit h.1 to the Registration Statement provides for each of the parties thereto, including the Registrant and the Underwriters, to indemnify the others, their trustees, directors, certain of their officers, trustees, directors and persons who control them against certain liabilities in connection with the offering described herein, including liabilities under the federal securities laws.

Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

EXHIBIT A.2

NUVEEN MUNICIPAL HIGH INCOME OPPORTUNITY FUND

S&P GUIDELINES

Below is set forth for its Nuveen Municipal High Income Opportunity Fund (the "Fund") the S&P Guidelines, as defined in the Statement Establishing and Fixing the Rights and Preferences of Municipal Auction Rate Cumulative Preferred Shares (the "Statement"). Capitalized terms not defined herein shall have the same meanings as defined in the Statement. S&P may amend, alter or change these S&P Guidelines, in its sole discretion, provided however, that S&P provide any such amendments, alterations or changes to the Fund in writing.

1. RATING AGENCY RESTRICTIONS.

For so long as any shares of MuniPreferred are Outstanding and S&P is then rating the shares of MuniPreferred, the Fund will not, unless it has received written confirmation from S&P (if S&P is then rating MuniPreferred), that any such action would not impair the rating then assigned by such rating agency to a series of MuniPreferred, engage in any one or more of the following transactions:

a. write unsecured put or uncovered call options on portfolio securities;

b. issue additional shares or series of MuniPreferred or any class or series of shares 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 reissue any shares of MuniPreferred previously purchased or redeemed by the Fund;

c. engage in any short sales of securities;

d. lend portfolio securities; or

e. merge or consolidate into or with any other corporation.

2. MUNIPREFERRED BASIC MAINTENANCE AMOUNT.

a. On or before 5:00 P.M., New York City time, on the third Business Day after a Valuation Date on which the Fund fails to satisfy the MuniPreferred Basic Maintenance Amount, and on the third Business Day after the MuniPreferred Basic Maintenance Cure Date with respect to such Valuation Date, the Fund shall complete and deliver to S&P (if S&P is then rating the shares of MuniPreferred) and the Auction Agent (if S&P is then rating the shares of MuniPreferred) a MuniPreferred Basic Maintenance Report as of the date of such failure or such MuniPreferred Basic Maintenance Cure Date, as the case may be, which will be deemed to have been delivered to the Auction Agent if the Auction Agent receives a copy or telecopy, telex or other electronic transcription thereof and on the same day the Fund mails to the Auction Agent for delivery on the next Business Day the full MuniPreferred Basic Maintenance Report. The Fund shall also deliver a MuniPreferred Basic Maintenance Report to (i) the Auction Agent (if S&P is then rating the shares of MuniPreferred) as of (A) the fifteenth day of each month (or, if such day is not a Business Day, the next succeeding Business Day) and (B) the last Business Day of each month and (ii) S&P (if S&P is then rating the shares of MuniPreferred) if and when


requested for any Valuation Date, on or before the third Business Day after such request. A failure by the Fund to deliver a MuniPreferred Basic Maintenance Report pursuant to the preceding sentence shall be deemed to be delivery of a MuniPreferred Basic Maintenance Report indicating the Discounted Value for all assets of the Fund is less than the MuniPreferred Basic Maintenance Amount, as of the relevant Valuation Date.

b. Within ten Business Days after the date of delivery of a MuniPreferred Basic Maintenance Report in accordance with paragraph a. above relating to a Quarterly Valuation Date, the Fund shall cause the Independent Accountant to confirm in writing to S&P (if S&P is then rating the shares of MuniPreferred) and the Auction Agent (if S&P is then rating the shares of MuniPreferred) (i) the mathematical accuracy of the calculations reflected in such Report (and in any other MuniPreferred Basic Maintenance Report, randomly selected by the Independent Accountant, that was delivered by the Fund during the quarter ending on such Quarterly Valuation Date), (ii) that, in such Report (and in such randomly selected Report), the Fund determined in accordance with the Statement whether the Fund had, at such Quarterly Valuation Date (and at the Valuation Date addressed in such randomly-selected Report), S&P Eligible Assets (if S&P is then rating the shares of MuniPreferred) of an aggregate Discounted Value at least equal to the MuniPreferred Basic Maintenance Amount (such confirmation being herein called the "Accountant's Confirmation"), (iii) with respect to the S&P ratings on Municipal Obligations, the issuer name, issue size and coupon rate listed in such Report, that the Independent Accountant has requested that S&P verify such information and the Independent Accountant shall provide a listing in its letter of any differences, (iv) with respect to the bid or mean price (or such alternative permissible factor used in calculating the Market Value) provided by the custodian of the Fund's assets to the Fund for purposes of valuing securities in the Fund's portfolio, the Independent Accountant has traced the price used in such Report to the bid or mean price listed in such Report as provided to the Fund and verified that such information agrees (in the event such information does not agree, the Independent Accountant will provide a listing in its letter of such differences) and (v) with respect to such confirmation to S&P, that the Fund has satisfied the requirements of
Section 13 of the Statement (such confirmation is herein called the "Accountant's Confirmation").

c. Within ten Business Days after the date of delivery of a MuniPreferred Basic Maintenance Report in accordance with paragraph a. above relating to any Valuation Date on which the Fund failed to satisfy the MuniPreferred Basic Maintenance Amount, and relating to the MuniPreferred Basic Maintenance Cure Date with respect to such failure to satisfy the MuniPreferred Basic Maintenance Amount, the Fund shall cause the Independent Accountant to provide to S&P (if S&P is then rating the shares of MuniPreferred) and the Auction Agent (if S&P is then rating the shares of MuniPreferred) an Accountant's Confirmation as to such MuniPreferred Basic Maintenance Report.

d. If any Accountant's Confirmation delivered pursuant to paragraph b. or c. above shows that an error was made in the MuniPreferred Basic Maintenance Report for a particular Valuation Date for which such Accountant's Confirmation was required to be delivered, or shows that a lower aggregate Discounted Value for the aggregate of all S&P Eligible Assets (if S&P is then rating the shares of MuniPreferred) of the Fund was determined by the Independent Accountant, the calculation or determination made by such Independent Accountant shall be final and conclusive and shall be binding on the Fund, and the Fund shall

2

accordingly amend and deliver the MuniPreferred Basic Maintenance Report to S&P (if S&P is then rating the shares of MuniPreferred) and the Auction Agent (if S&P is then rating the shares of MuniPreferred) promptly following receipt by the Fund of such Accountant's Confirmation.

e. On or before 5:00 p.m., New York City time, on the first Business Day after the Date of Original Issue of any shares of MuniPreferred, the Fund shall complete and deliver to S&P (if S&P is then rating the shares of MuniPreferred) a MuniPreferred Basic Maintenance Report as of the close of business on such Date of Original Issue. Within five Business Days of such Date of Original Issue, the Fund shall cause the Independent Accountant to confirm in writing to S&P (if S&P is then rating the shares of MuniPreferred) (i) the mathematical accuracy of the calculations reflected in such Report and (ii) that the Discounted Value of S&P Eligible Assets reflected thereon equals or exceeds the MuniPreferred Basic Maintenance Amount reflected thereon.

f. On or before 5:00 p.m., New York City time, on the third Business Day after either (i) the Fund shall have redeemed Common Shares or (ii) the ratio of the Discounted Value of S&P Eligible Assets to the MuniPreferred Basic Maintenance Amount is less than or equal to 105% or (iii) whenever requested by S&P, the Fund shall complete and deliver to S&P (if S&P is then rating the shares of MuniPreferred), as the case may be, a MuniPreferred Basic Maintenance Report as of the date of either such event.

3. DEFINITIONS.

a. "ESCROWED BONDS" shall mean Municipal Obligations that (i) have been determined to be legally defeased in accordance with S&P's legal defeasance criteria, (ii) have been determined to be economically defeased in accordance with S&P's economic defeasance criteria and assigned a rating of AAA by S&P, (iii) are not rated by S&P but have been determined to be legally defeased by S&P or (iv) have been determined to be economically defeased by S&P and assigned a rating no lower than the rating that is S&P equivalent of S&P's AAA rating. In the event that a defeased obligation which is an S&P Eligible Asset does not meet the criteria of an Escrowed Bond, such Municipal Obligation will be deemed to remain in the Issue Type Category into which it fell prior to such defeasance.

b. "INVERSE FLOATER" shall mean trust certificates or other instruments evidencing interests in one or more Municipal Obligations that qualify as S&P Eligible Assets, the interest rates on which are adjusted at short-term intervals on a basis that is inverse to the simultaneous readjustment of the interest rates on corresponding floating rate trust certificates or other instruments issued by the same issuer, provided that the ratio of the aggregate dollar amount of floating rate instruments to inverse floating rate instruments issued by the same issuer does not exceed one to one at their time of original issuance.

c. "MUNIPREFERRED BASIC MAINTENANCE AMOUNT" as of any Valuation Date, shall mean the dollar amount equal to the sum of (i)(A) the product of the number of shares of MuniPreferred outstanding on such date multiplied by $25,000 (plus the product of the number of shares of any other series of Preferred Shares outstanding on such date multiplied by the liquidation preference of such shares), plus any redemption premium applicable to shares of MuniPreferred (or other Preferred Shares) then subject to redemption; (B) the aggregate amount

3

of dividends that will have accumulated at the respective Applicable Rates (whether or not earned or declared) to (but not including) the first respective Dividend Payment Dates for shares of MuniPreferred outstanding that follow such Valuation Date (plus the aggregate amount of dividends, whether or not earned or declared, that will have accumulated in respect of other outstanding Preferred Shares to, but not including, the first respective dividend payment dates for such other shares that follow such Valuation Date); (C) the aggregate amount of dividends that would accumulate on shares of each series of MuniPreferred outstanding from such first respective Dividend Payment Date therefor through the 56th day after such Valuation Date, at the Maximum Rate (calculated as if such Valuation Date were the Auction Date for the Rate Period commencing on such Dividend Payment Date) for a Minimum Rate Period of shares of such series to commence on such Dividend Payment Date, assuming, solely for purposes of the foregoing, that if on such Valuation Date the Fund shall have delivered a Notice of Special Rate Period to the Auction Agent pursuant to Section 4(d)(i) of Part I of the Statement with respect to shares of such series, such Maximum Rate shall be the higher of (a) the Maximum Rate for the Special Rate Period of shares of such series to commence on such Dividend Payment Date and (b) the Maximum Rate for a Minimum Rate Period of shares of such series to commence on such Dividend Payment Date, multiplied by the Volatility Factor applicable to a Minimum Rate Period, or, in the event the Fund shall have delivered a Notice of Special Rate Period to the Auction Agent pursuant to Section 4(d)(i) of Part I of the Statement with respect to shares of such series designating a Special Rate Period consisting of 56 Rate Period Days or more, the Volatility Factor applicable to a Special Rate Period of that length (plus the aggregate amount of dividends that would accumulate at the maximum dividend rate or rates on any other Preferred Shares outstanding from such respective dividend payment dates through the 56th day after such Valuation Date, as established by or pursuant to the respective statements establishing and fixing the rights and preferences of such other Preferred Shares) (except that (1) if such Valuation Date occurs at a time when a Failure to Deposit (or, in the case of Preferred Shares other than MuniPreferred, a failure similar to a Failure to Deposit) has occurred that has not been cured, the dividend for purposes of calculation would accumulate at the current dividend rate then applicable to the shares in respect of which such failure has occurred and (2) for those days during the period described in this subparagraph (C) in respect of which the Applicable Rate in effect immediately prior to such Dividend Payment Date will remain in effect (or, in the case of Preferred Shares other than MuniPreferred, in respect of which the dividend rate or rates in effect immediately prior to such respective dividend payment dates will remain in effect), the dividend for purposes of calculation would accumulate at such Applicable Rate (or other rate or rates, as the case may be) in respect of those days); (D) the amount of anticipated expenses of the Fund for the 90 days subsequent to such Valuation Date; (E) the amount of the Fund's Maximum Potential Gross-up Payment Liability in respect of shares of MuniPreferred (and similar amounts payable in respect of other Preferred Shares pursuant to provisions similar to those contained in Section 3 of Part I of the Statement) as of such Valuation Date; and (F) any current liabilities as of such Valuation Date to the extent not reflected in any of (i)(A) through (i)(E) (including, without limitation, any payables for Municipal Obligations purchased as of such Valuation Date and any liabilities incurred for the purpose of clearing securities transactions) less (ii) the value (i.e., for purposes of current S&P guidelines, the face value of cash, short-term Municipal Obligations rated SP-1 or A-1 or Municipal Obligations rated A, provided in each case that such securities mature on or prior to the date upon which any of (i)(A) though
(i)(F) became payable,

4

otherwise the S&P Discounted Value) of any of the Fund's assets irrevocably deposited by the Fund for the payment of any of (i)(A) through (i)(F).

d. "MUNIPREFERRED BASIC MAINTENANCE CURE DATE," with respect to the failure by the Fund to satisfy the MuniPreferred Basic Maintenance Amount (as required by paragraph (a) of Section 7 of Part I of the Statement) as of a given Valuation Date, shall mean the seventh Business Day following such Valuation Date.

e. "MUNIPREFERRED BASIC MAINTENANCE REPORT" shall mean a report signed by the President, Treasurer or any Senior Vice President or Vice President of the Fund which sets forth, as of the related Valuation Date, the assets of the Fund, the Market Value and the Discounted Value thereof (seriatim and in aggregate), and the MuniPreferred Basic Maintenance Amount.

f. "S&P DISCOUNT FACTOR" shall mean, for purposes of determining the Discounted Value of any S&P Eligible Asset, the percentage determined by reference to the rating on such asset and the shortest Exposure Period set forth opposite such rating that is the same length as or is longer than the S&P Exposure Period, in accordance with the table set forth below:

to as "High Yield Securities") may comprise no more than 20% of the short-term Municipal Obligations that qualify as S&P Eligible Assets; (ii) the S&P Discount Factor for Receivables for Municipal Obligations Sold that are due in more than five Business Days from such Valuation Date will be the S&P Discount Factor applicable to the Municipal Obligations sold; (iii) no S&P Discount Factor will be applied to cash [or Money Market Funds rated "AAAm" by S&P with effective next day maturities] or to Receivables for Municipal Obligations Sold if such receivables are due within five Business Days of such Valuation Date; and (iv) except as set forth in clause (i) above, in the case of any Municipal Obligation that is not rated by S&P but qualifies as an S&P Eligible Asset pursuant to clause (iii) of that definition, such Municipal Obligation will be deemed to have an S&P rating one full rating category lower than the S&P rating category that is the equivalent of the rating category in which such Municipal Obligation is placed by a nationally recognized statistical rating organization. "Receivables for Municipal Obligations Sold," for purposes of calculating S&P Eligible Assets as of any Valuation Date, means the book value of receivables for Municipal Obligations sold as of or prior to such Valuation Date. For purposes of the foregoing, Anticipation Notes rated "SP-1+" or, if not rated by S&P, equivalent to "A-1+" or "SP-1+" by another nationally recognized statistical rating organization, on a case by case basis, which do not mature or have a demand feature at par exercisable in 30 days and which do not have a long-term rating, shall be considered to be short-term Municipal Obligations.

g. "S&P ELIGIBLE ASSET" shall mean cash (excluding any cash irrevocably deposited by the Trust for the payment of any liabilities within the meaning of MuniPreferred Basic Maintenance Amount), Receivables for Municipal Obligations Sold, or a Municipal Obligation owned by the Fund that (i) is interest bearing and pays interest at least semi-annually; (ii) is payable with respect to principal and interest in U.S. Dollars; (iii) is not subject to a covered call or put option written by the Fund; (iv) except for Inverse Floaters, is not part of a private placement of Municipal Obligations; and (v) except for Inverse Floaters, is part of an issue of Municipal Obligations with an original issue size of at least $10 million. Any Municipal Obligation that is a part of an original issue size of less than $10 million must carry a rating of at least "AA" by S&P or "AAA" by another nationally recognized statistical rating organization. Solely for purposes of this definition, the term "Municipal Obligation" means any obligation the interest on which is exempt from regular Federal income taxation and which is issued by any of the fifty United States, the District of Columbia or any of the territories of the United States, their subdivisions, counties, cities, towns, villages, school districts and agencies (including authorities and special districts created by the states), and federally sponsored agencies such as local housing authorities. Notwithstanding the foregoing limitations:

(i) Municipal Obligations (excluding Escrowed Bonds) of any one issuer or guarantor (excluding bond insurers) shall be considered S&P Eligible Assets only to the extent the Market Value of such Municipal Obligations (including short-term Municipal Obligations) does not exceed 10% of the aggregate Market Value of S&P Eligible Assets, provided that 2% is added to the applicable S&P Discount Factor for every 1% by which the Market Value of such Municipal Obligations exceeds 5% of the aggregate Market Value of S&P Eligible Assets or for any percentage over 5% add 10 percentage points to the S&P Discount Factor. High Yield Securities of any one issuer shall be considered S&P Eligible Assets only to the extent the Market Value of such Municipal Obligations does not exceed 5% of the aggregate Market Value of S&P

6

Eligible Assets. Non-rated securities of any issuer shall be considered S&P Eligible Assets to the extent the Market Value of such Municipal Obligation does not exceed 5% of the aggregate Market Value of S&P Eligible Assets. No more than 10% of the aggregate Market Value of the portfolio may consist of non-rated securities;

(ii) Municipal Obligations not rated by S&P shall be considered S&P Eligible Assets only to the extent the Market Value of such Municipal Obligations does not exceed 50% of the aggregate Market Value of S&P Eligible Assets; provided, however, that High Yield Securities shall be considered S&P Eligible Assets only to the extent the Market Value of such Municipal Obligations does not exceed 20% of the aggregate Market Value of S&P Eligible Assets;

(iii) Municipal Obligations issued by issuers in any one state or territory will be considered S&P Eligible Assets only to the extent that the Market Value of such Municipal Obligations does not exceed 25% of the aggregate Market Value of S&P Eligible Assets; and

(iv) Municipal Obligations (excluding Escrowed Bonds) of any one state or territory shall be considered S&P Eligible Assets only to the extent the Market Value of such Municipal Obligations does not exceed 25% of the aggregate Market Value of S&P Eligible Assets.

h. "S&P EXPOSURE PERIOD" shall mean the sum of (i) that number of days from the last Valuation Date on which the Trust's Discounted Value of S&P Eligible Assets were greater than the MuniPreferred Basic Maintenance Amount to the Valuation Date on which the Fund's Discounted Value of S&P Eligible Assets failed to exceed the MuniPreferred Basic Maintenance Amount, (ii) the maximum number of days following a Valuation Date that the Fund has under the Statement to cure any failure to maintain a Discounted Value of S&P Eligible Assets at least equal to the MuniPreferred Basic Maintenance Amount, and (iii) the maximum number of days the Fund has to effect a mandatory redemption under
Section 11(b) of the Statement.

i. "S&P VOLATILITY FACTOR" shall mean, as of any Valuation Date, a multiplicative factor equal to (i) 305% in the case of any Minimum Rate Period or any Special Rate Period of 28 Rate Period Days or fewer, (ii) 268% in the case of any Special Rate Period of more than 28 Rate Period Days but fewer than 183 Rate Period Days; and (iii) 204% in the case of any Special Rate Period of more than 182 Rate Period Days.

4. CERTAIN OTHER RESTRICTIONS AND REQUIREMENTS.

a. For so long as any MuniPreferred are rated by S&P, the Fund will not purchase or sell futures contracts, write, purchase of sell options on futures contracts, write put options (except covered put options) or call options (except covered call options) on portfolio securities unless it receives written confirmation from S&P that engaging in such transactions will not impair the ratings then assigned to the MuniPreferred by S&P, except that the Fund may purchase or sell futures contracts based on the Bond Buyer Municipal Bond Index (the "Municipal Index") or United States Treasury Bonds or Notes ("Treasury Bonds") and write,

7

purchase or sell put and call options on such contracts or engage in interest rate swaps, caps and floors (collectively "S&P Hedging Transactions"), subject to the following limitations:

(i) the Fund will not engage in any S&P Hedging Transaction based on the Municipal Index (other than transactions which terminate a futures contract or option held by the Fund's taking an opposite position thereto), which would cause the Fund at the time of such transaction to own or have sold the least of (A) more than 1,000 outstanding futures contracts based on the Municipal Index, (B) outstanding futures contracts based on the Municipal Index exceeding in number 25% of the quotient of the Market Value of the Fund's total assets divided by $1,000 or (C) outstanding futures contracts based on the Municipal Index exceeding in number 10% of average number of daily traded futures contracts on the Municipal Index in the 30 days preceding the time of effecting such transaction as reported by The Wall Street Journal;

(ii) the Fund will not engage in any S&P Hedging Transaction based on Treasury Bonds (other than Closing Transactions) which would cause the Fund at the time of such transaction to own or have sold the lesser of (A) outstanding futures contracts based on Treasury Bonds exceeding in number 50% of the quotient of the Market Value of the Fund's total assets divided by $100,0000 ($200,000 in the case of the two-year United States Treasury Note) or (B) outstanding futures contracts based on Treasury Bonds exceeding in number 10% of the average number of daily traded futures contracts based on Treasury Bonds in the 30 days preceding the time of effecting such transaction as reported by The Wall Street Journal;

(iii) the Fund will engage in Closing Transactions to close out any outstanding futures contract which the Trust owns or has sold or any outstanding option thereon owned by the Fund in the event (A) the Fund does not have S&P Eligible Assets with an aggregate Discounted Value equal to or greater than the MuniPreferred Basic Maintenance Amount on two consecutive Valuation Dates and (B) the Fund is required to pay variation margin on the second such Valuation Date;

(iv) the Fund will engage in a Closing Transaction to close out any outstanding futures contract or option thereon in the month prior to the delivery month under the terms of such futures contract or option thereon unless the Fund holds the securities deliverable under such terms; and

(v) when the Fund writes a futures contract or option thereon, it will either maintain any amount of cash, cash equivalents or high grade (rated A or better by S&P), fixed-income securities in a segregated account with the Fund's custodian, so that the amount so segregated plus the amount of initial margin and variation margin held in the account of or on behalf of the Fund's broker with respect to such futures contract or option equals the Market Value of the futures contract or option, or, in the event the Fund writes a futures contract or option thereon which requires delivery of an underlying security, it shall hold such underlying security in its portfolio.

For purposes of determining whether the Fund has S&P Eligible Assets with a Discounted Value that equals or exceeds the MuniPreferred Basic Maintenance Amount, the

8

Discounted Value of cash or securities held for the payment of initial margin or variation margin shall be zero and the aggregate Discounted Value of S&P Eligible Assets shall be reduced by an amount equal to (i) 30% of the aggregate settlement value, as marked to market, of any outstanding futures contracts based on the Municipal Index which are owned by the Fund plus (ii) 25% of the aggregate settlement value, as marked to market, of any outstanding futures contracts based on Treasury Bonds which contracts are owned by the Fund.

Moody's may amend, alter or change these Moody's Guidelines, in its sole discretion, provided however, that Moody's provide any such amendments, alterations or changes to the Fund in writing.

1. RATING AGENCY RESTRICTIONS.

For so long as any shares of MuniPreferred are Outstanding and Moody's is then rating the shares of MuniPreferred, the Fund will not, unless it has received written confirmation from Moody's (if Moody's is then rating MuniPreferred), that any such action would not impair the rating then assigned by such rating agency to a series of MuniPreferred, engage in any one or more of the following transactions:

a. write unsecured put or uncovered call options on portfolio securities;

b. issue additional shares or series of MuniPreferred or any class or series of shares 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 reissue any shares of MuniPreferred previously purchased or redeemed by the Fund;

c. engage in any short sales of securities;

d. lend portfolio securities; or

e. merge or consolidate into or with any other corporation.

2. MUNIPREFERRED BASIC MAINTENANCE AMOUNT.

a. On or before 5:00 P.M., New York City time, on the third Business Day after a Valuation Date on which the Fund fails to satisfy the MuniPreferred Basic Maintenance Amount, and on the third Business Day after the MuniPreferred Basic Maintenance Cure Date with respect to such Valuation Date, the Fund shall complete and deliver to Moody's (if Moody's is then rating the shares of MuniPreferred) and the Auction Agent (if Moody's is then rating the shares of MuniPreferred) a MuniPreferred Basic Maintenance Report as of the date of such failure or such MuniPreferred Basic Maintenance Cure Date, as the case may be, which will be deemed to have been delivered to the Auction Agent if the Auction Agent receives a copy or telecopy, telex or other electronic transcription thereof and on the same day the Fund mails to the Auction Agent for delivery on the next Business Day the full MuniPreferred Basic Maintenance Report. The Fund shall also deliver a MuniPreferred Basic Maintenance Report to
(i) the Auction Agent (if Moody's is then rating the shares of MuniPreferred) as of (A) the fifteenth day of each month (or, if such day is not a Business Day, the next succeeding Business Day) and


(B) the last Business Day of each month and (ii) Moody's (if Moody's is then rating the shares of MuniPreferred) as of any Quarterly Valuation Date, in each case on or before the third Business Day after such day. A failure by the Fund to deliver a MuniPreferred Basic Maintenance Report pursuant to the preceding sentence shall be deemed to be delivery of a MuniPreferred Basic Maintenance Report indicating the Discounted Value for all assets of the Fund is less than the MuniPreferred Basic Maintenance Amount, as of the relevant Valuation Date.

b. Within ten Business Days after the date of delivery of a MuniPreferred Basic Maintenance Report in accordance with paragraph a. above relating to a Quarterly Valuation Date, the Fund shall cause the Independent Accountant to confirm in writing to Moody's (if Moody's is then rating the shares of MuniPreferred) and the Auction Agent (if Moody's is then rating the shares of MuniPreferred) (i) the mathematical accuracy of the calculations reflected in such Report (and in any other MuniPreferred Basic Maintenance Report, randomly selected by the Independent Accountant, that was delivered by the Fund during the quarter ending on such Quarterly Valuation Date), (ii) that, in such Report (and in such randomly selected Report), the Fund determined in accordance with this Statement whether the Fund had, at such Quarterly Valuation Date (and at the Valuation Date addressed in such randomly selected Report), Moody's Eligible Assets (if Moody's is then rating the shares of MuniPreferred) of an aggregate Discounted Value at least equal to the MuniPreferred Basic Maintenance Amount (such confirmation being herein called the "Accountant's Confirmation"), (iii) with respect to the Moody's ratings on Municipal Obligations, the issuer name, issue size and coupon rate listed in such Report, that such information has been verified by Moody's (in the event such information is not verified by Moody's, the Independent Accountant will inquire of Moody's what such information is, and provide a listing in its letter of any differences), (iv) with respect to the bid or mean price (or such alternative permissible factor used in calculating the Market Value) provided by the custodian of the Fund's assets to the Fund for purposes of valuing securities in the Fund's portfolio, the Independent Accountant has traced the price used in such Report to the bid or mean price listed in such Report as provided to the Fund and verified that such information agrees (in the event such information does not agree, the Independent Accountant will provide a listing in its letter of such differences) and (v) with respect to such confirmation to Moody's, that the Fund has satisfied the requirements of Section 13 of the Statement (such confirmation is herein called the "Accountant's Confirmation").

c. Within ten Business Days after the date of delivery of a MuniPreferred Basic Maintenance Report in accordance with paragraph a. above relating to any Valuation Date on which the Fund failed to satisfy the MuniPreferred Basic Maintenance Amount, and relating to the MuniPreferred Basic Maintenance Cure Date with respect to such failure to satisfy the MuniPreferred Basic Maintenance Amount, the Fund shall cause the Independent Accountant to provide to Moody's (if Moody's is then rating the shares of MuniPreferred) and the Auction Agent (if Moody's is then rating the shares of MuniPreferred) an Accountant's Confirmation as to such MuniPreferred Basic Maintenance Report.

d. If any Accountant's Confirmation delivered pursuant to paragraph b. or c. above shows that an error was made in the MuniPreferred Basic Maintenance Report for a particular Valuation Date for which such Accountant's Confirmation was required to be delivered, or shows that a lower aggregate Discounted Value for the aggregate of all Moody's Eligible Assets (if Moody's is then rating the shares of MuniPreferred), as the case may be, of

2

the Fund was determined by the Independent Accountant, the calculation or determination made by such Independent Accountant shall be final and conclusive and shall be binding on the Fund, and the Fund shall accordingly amend and deliver the MuniPreferred Basic Maintenance Report to Moody's (if Moody's is then rating the shares of MuniPreferred) and the Auction Agent (if Moody's is then rating the shares of MuniPreferred) promptly following receipt by the Fund of such Accountant's Confirmation.

e. On or before 5:00 p.m., New York City time, on the first Business Day after the Date of Original Issue of any shares of MuniPreferred, the Fund shall complete and deliver to Moody's (if Moody's is then rating the shares of MuniPreferred) a MuniPreferred Basic Maintenance Report as of the close of business on such Date of Original Issue.

f. On or before 5:00 p.m., New York City time, on the third Business Day after either (i) the Fund shall have redeemed Common Shares or (ii) the ratio of the Discounted Value of Moody's Eligible Assets to the MuniPreferred Basic Maintenance Amount is less than or equal to 105% or (iii) whenever requested by Moody's, the Fund shall complete and deliver to Moody's (if Moody's is then rating the shares of MuniPreferred) a MuniPreferred Basic Maintenance Report as of the date of either such event.

Notwithstanding the foregoing, (i) the Moody's Discount Factor for short-term Municipal Obligations will be 115%, so long as such Municipal Obligations are rated at least MIG-1, VMIG-l or P-1 by Moody's and mature or have a demand feature at par exercisable in 30 days or less or 125% as long as such Municipal Obligations are rated at least A-1+/AA or SP-1+/AA by S&P and mature or have a demand feature at par exercisable in 30 days or less and (ii) no Moody's Discount Factor will be applied to cash or to Receivables for Municipal Obligations Sold.

c. "MOODY'S ELIGIBLE ASSETS" shall mean cash, Receivables for Municipal Obligations Sold or a Municipal Obligation that (i) pays interest in cash, (ii) does not have its Moody's rating, as applicable, suspended by Moody's, and (iii) is part of an issue of Municipal Obligations of at least $10,000,000. Municipal Obligations issued by any one issuer and rated BBB or lower by S&P, Ba or B by Moody's or not rated by S&P and Moody's ("Other Securities") may comprise no more than 4% of total Moody's Eligible Assets; such Other Securities, if any, together with any Municipal Obligations issued by the same issuer and rated Baa by Moody's or A by S&P, may comprise no more than 6% of total Moody's Eligible Assets; such Other Securities, Baa and A-rated Municipal Obligations, if any, together with any Municipal Obligations issued by the same issuer and rated A by Moody's or AA by S&P, may comprise no more than 10% of total Moody's Eligible Assets; and such Other Securities, Baa, A and AA-rated Municipal Obligations, if any, together with any Municipal Obligations issued by the same issuer and rated Aa by Moody's or AAA by S&P, may comprise no more than 20% of total Moody's Eligible Assets. For purposes of the foregoing sentence, any Municipal Obligation backed by the guaranty, letter of credit or insurance issued by a third party shall be deemed to be issued by such third party if the issuance of such third party credit is the sole determinant of the rating on such Municipal Obligation. Other Securities issued by issuers located within a single state or territory may comprise no more than 12% of total Moody's Eligible Assets; such Other Securities, if any, together with any Municipal Obligations issued by issuers located within a single state or territory and rated Baa by Moody's or A by S&P, may comprise no more than 20% of total Moody's Eligible Assets; such Other Securities, Baa and A-rated Municipal Obligations, if any, together with any Municipal Obligations issued by issuers located within a single state or territory and rated A by Moody's or AA by S&P, may comprise no more than 40% of total Moody's Eligible Assets; and such Other Securities, Baa, A and AA-rated Municipal Obligations, if any, together with any Municipal Obligations issued by issuers located within a single state or territory and rated Aa by Moody's or AAA by S&P, may comprise no more than 60% of total Moody's Eligible Assets.

When the Fund sells a Municipal Obligation and agrees to repurchase such Municipal Obligation at a future date, such Municipal Obligation shall be valued at its Discounted Value for purposes of determining Moody's Eligible Assets, and the amount of the repurchase price of such Municipal Obligation shall be included as a liability for purposes of calculating the MuniPreferred Basic Maintenance Amount. When the Fund purchases a Moody's Eligible Asset and agrees to sell it at a future date, such Eligible Asset shall be valued at the amount of cash to be received by the Fund upon such future date, provided that the

4

counterparty to the transaction has a long-term debt rating of at least A2 from Moody's and the transaction has a term of no more than 30 days, otherwise such Eligible Asset shall be valued at the Discounted Value of such Eligible Asset.

Notwithstanding the foregoing, an asset will not be considered a Moody's Eligible Asset to the extent it is (i) subject to any material lien, mortgage, pledge, security interest or security agreement of any kind (collectively, "Liens"), except for (a) Liens which are being contested in good faith by appropriate proceedings and which Moody's has indicated to the Fund will not affect the status of such asset as a Moody's Eligible Asset, (b) Liens for taxes that are not then due and payable or that can be paid thereafter without penalty, (c) Liens to secure payment for services rendered or cash advanced to the Fund by Nuveen Advisory Corp., Chase Manhattan Bank or the Auction Agent and (d) Liens by virtue of any repurchase agreement; or (ii) deposited irrevocably for the payment of any liabilities for purposes of determining the MuniPreferred Basic Maintenance Amount.

d. "MOODY'S EXPOSURE PERIOD" shall mean the period commencing on a given Valuation Date and ending 56 days thereafter.

e. "MOODY'S VOLATILITY FACTOR" shall mean, as of any Valuation Date, (i) in the case of any Minimum Rate Period, any Special Rate Period of 28 Rate Period Days or fewer, or any Special Rate Period of 57 Rate Period Days or more, a multiplicative factor equal to 275%, except as otherwise provided in the last sentence of this definition; (ii) in the case of any Special Rate Period of more than 28 but fewer than 36 Rate Period Days, a multiplicative factor equal to 203%; (iii) in the case of any Special Rate Period of more than 35 but fewer than 43 Rate Period Days, a multiplicative factor equal to 217%; (iv) in the case of any Special Rate Period of more than 42 but fewer than 50 Rate Period Days, a multiplicative factor equal to 226%; and (v) in the case of any Special Rate Period of more than 49 but fewer than 57 Rate Period Days, a multiplicative factor equal to 235%. If, as a result of the enactment of changes to the Code, the greater of the maximum marginal Federal individual income tax rate applicable to ordinary income and the maximum marginal Federal corporate income tax rate applicable to ordinary income will increase, such increase being rounded up to the next five percentage points (the "Federal Tax Rate Increase"), until the effective date of such increase, the Moody's Volatility Factor in the case of any Rate Period described in (i) above in this definition instead shall be determined by reference to the following table:

 FEDERAL TAX

6

Obligations rated MIG-1, VMIG-1 or P-1, and short-term securities that are direct obligations of the U.S. Government, provided in each case that such securities mature on or prior to the date upon which any of (i)(A) though (i)(F) became payable, otherwise the Moody's Discounted Value) of any of the Fund's assets irrevocably deposited by the Fund for the payment of any of (i)(A) through (i)(F).

h. "MUNIPREFERRED BASIC MAINTENANCE REPORT" shall mean a report signed by the President, Treasurer or any Senior Vice President or Vice President of the Fund which sets forth, as of the related Valuation Date, the assets of the Fund, the Market Value and the Discounted Value thereof (seriatim and in aggregate), and the MuniPreferred Basic Maintenance Amount.

2. CERTAIN OTHER RESTRICTIONS AND REQUIREMENTS.

a. For so long as any MuniPreferred are rated by Moody's, the Fund will not buy or sell futures contracts, write, purchase or sell call options on futures contracts or purchase put options on futures contracts or write call options (except covered call options) on portfolio securities unless it receives written confirmation from Moody's that engaging in such transactions would not impair the ratings then assigned to the MuniPreferred by Moody's, except that the Fund may purchase or sell exchange-traded futures contracts based on the Municipal Index or Treasury Bonds and purchase, write or sell exchange-traded put options on such futures contracts and purchase, write or sell exchange-traded call options on such futures contracts (collectively, "Moody's Hedging Transactions"), subject to the following limitations:

(i) the Fund will not engage in any Moody's Hedging Transaction based on the Municipal Index (other than Closing Transactions), which would cause the Fund at the time of such transaction to own or have sold (A) outstanding futures contracts based on the Municipal Index exceeding in number 10% of the average number of daily traded futures contracts based on the Municipal Index in the 30 days preceding the time of effecting such transaction as reported by The Wall Street Journal or (B) outstanding futures contracts based on the Municipal Index having a Market Value exceeding 50% of the Market Value of all Municipal Bonds constituting Moody's Eligible Assets owned by the Fund (other than Moody's Eligible Assets already subject to a Moody's Hedging Transaction);

(ii) the Fund will not engage in any Moody's Hedging Transaction based on Treasury Bonds (other than Closing Transactions) which would cause the Fund at the time of such transaction to own or have sold (A) outstanding futures contracts based on Treasury Bonds having an aggregate Market Value exceeding 20% of the aggregate Market Value of Moody's Eligible Assets owned by the Fund and rated Aa by Moody's (or, if not rated by Moody's but rated by S&P, rated AAA by S&P) or (B) outstanding futures contracts based on Treasury Bonds having an aggregate Market

7

Value exceeding 40% of the aggregate Market Value of all Municipal Bonds constituting Moody's Eligible Assets owned by the Fund (other than Moody's Eligible Assets already subject to a Moody's Hedging Transaction) and rated Baa or A by Moody's (or, if not rated by Moody's but rated by S&P, rated A or AA by S&P) (for purposes of the foregoing clauses (i) and (ii), the Fund shall be deemed to own the number of futures contracts that underlie any outstanding options written by the Fund);

(iii) the Fund will engage in Closing Transactions to close out any outstanding futures contract based on the Municipal Index if the amount of open interest in the Municipal Index as reported by The Wall Street Journal is less than 5,000;

(iv) the Fund will engage in a Closing Transaction to close out any outstanding futures contract by no later than the fifth Business Day of the month in which such contract expires and will engage in a Closing Transaction to close out any outstanding option on a futures contract by no later than the first Business Day of the month in which such option expires;

(v) the Fund will engage in Moody's Hedging Transactions only with respect to futures contracts or options thereon having the next settlement date or the settlement date immediately thereafter;

(vi) the Fund will not engage in options and futures transactions for leveraging or speculative purposes and will not write any call options or sell any futures contracts for the purpose of hedging the anticipated purchase of an asset prior to completion of such purchase; and

(vii) the Fund will not enter into an option or futures transaction unless, after giving effect thereto, the Fund would continue to have Moody's Eligible Assets with an aggregate Discounted Value equal to or greater than the MuniPreferred Basic Maintenance Amount.

For purposes of determining whether the Fund has Moody's Eligible Assets with an aggregate Discounted Value that equals or exceeds the MuniPreferred Basic Maintenance Amount, the Discounted Value of Moody's Eligible Assets which the Fund is obligated to deliver or receive pursuant to an outstanding futures contract or option shall be as follows: (i) assets subject to call options written by the Fund which are either exchange-traded and "readily reversible" or which expire within 49 days after the date as of which such valuation is made shall be valued at the lesser of (a) Discounted Value and
(b) the exercise price of the call option written by the Fund; (ii) assets subject to call options written by the Fund not meeting the requirements of clause (i) of this sentence shall have no value; (iii) assets subject to put options written by the Fund shall be valued at the lesser of (A) the exercise price and (B) the Discounted Value of the subject security; (iv) futures contracts shall be valued at the lesser of (A) settlement price and (B) the Discounted Value of the subject security, provided that, if a contract matures within 49 days after the date as of which such valuation is made, where the Fund is the seller the contract may be valued at the settlement price and where the Fund is the buyer the contract may be valued at the Discounted Value of the subject securities; and (v) where delivery may be made

8

to the Fund with any security of a class of securities, the Fund shall assume that it will take delivery of the security with the lowest Discounted Value.

For purposes of determining whether the Fund has Moody's Eligible Assets with an aggregate Discounted Value that equals or exceeds the MuniPreferred Basic Maintenance Amount, the following amounts shall be subtracted from the aggregate Discounted Value of the Moody's Eligible Assets held by the Fund: (i) 10% of the exercise price of a written call option; (ii) the exercise price of any written put option; (iii) where the Fund is the seller under a futures contract, 10% of the settlement price of the futures contract;
(iv) where the Fund is the purchaser under a futures contract, the settlement price of assets purchased under such futures contract; (v) the settlement price of the underlying futures contract if the Fund writes put options on a futures contract; and (vi) 105% of the Market Value of the underlying futures contracts if the Fund writes call options on a futures contract and does not own the underlying contract.

b. For so long as any MuniPreferred are rated by Moody's, the Fund will not enter into any contract to purchase securities for a fixed price at a future date beyond customary settlement time (other than such contracts that constitute Moody's Hedging Transactions that are permitted under Section 13 of the Statement), except that the Fund may enter into such contracts to purchase newly-issued securities on the date such securities are issued ("Forward Commitments"), subject to the following limitation:

(i) the Fund will maintain in a segregated account with its custodian cash, cash equivalents or short-term, fixed-income securities rated P-1, MTG-1 or VMIG-1 by Moody's and maturing prior to the date of the Forward Commitment with a Market Value that equals or exceeds the amount of the Fund's obligations under any Forward Commitments to which it is from time to time a party or long-term fixed income securities with a Discounted Value that equals or exceeds the amount of the Fund's obligations under any Forward Commitment to which it is from time to time a party; and

(ii) the Fund will not enter into a Forward Commitment unless, after giving effect thereto, the Fund would continue to have Moody's Eligible Assets with an aggregate Discounted Value equal to or greater than the MuniPreferred Maintenance Amount.

For purposes of determining whether the Fund has Moody's Eligible Assets with an aggregate Discounted Value that equals or exceeds the MuniPreferred Basic Maintenance Amount, the Discounted Value of all Forward Commitments to which the Fund is a party and of all securities deliverable to the Fund pursuant to such Forward Commitments shall be zero.

(xii) None of the issuance and sale of the Securities by the Fund pursuant to this Agreement, the execution and delivery of this Agreement or any of the Fund Agreements by the Fund, or the performance by the Fund of its agreements under this Agreement or any of the Fund Agreements (A) requires any consent, approval, authorization or other order of or registration or filing with, the Commission, the National Association of Securities Dealers, Inc., or any national securities exchange or governmental body or agency or, arbitrator or court of the United States of America, State of Illinois or the Commonwealth of Massachusetts (except (1) the absence of which, either individually or in the aggregate, would not have a material adverse effect on the Fund; (2) such as may have been obtained prior to the date hereof; and (3) such as may be required for compliance with the American Stock Exchange or state securities or Blue Sky laws of various jurisdictions in accordance with this Agreement) or violates or will violate or constitutes or will constitute a breach of any of the provisions of the Organizational Documents of the Fund or (B) violates or will violate or constitutes or will constitute a breach of, or a default under, any material agreement, indenture, lease or other instrument known to such counsel to which the Fund is party or by which it or any of its properties may be bound, or violates any existing material United States of America, State of Illinois or the Commonwealth of Massachusetts statute, law, regulation (assuming compliance with all applicable state securities and Blue Sky laws), or judgment, injunction, order or decree known to us and applicable to the Fund or any of its properties, or will result in the creation or imposition of any material lien, charge or encumbrance upon any property or assets of the Fund pursuant to the terms of any agreement or instrument known to such counsel to which the Fund is a party or by which any of its property or assets is bound.

governmental authority or administrative agency of the United States of America, the State of Illinois or the Commonwealth of Massachusetts;

(xiii) No holder of any security of the Fund has any right pursuant to any agreement known to such counsel to which the Fund is a party to require registration of shares of beneficial interest, FundPreferred shares or any other security of the Fund because of the filing of the Registration Statement or consummation of the transactions contemplated by this Agreement; and

(xiv) To the best of such counsel's knowledge, there are no agreements, contracts, indentures, leases or other instruments that are required to be described in the Registration Statement or the Prospectus, or to be filed as an exhibit to the Registration Statement that are not described or filed as required by the 1933 Act, the 1940 Act or the Rules and Regulations.

Such counsel shall also state that although counsel has not undertaken, except as otherwise indicated in their opinion, to determine independently and does not assume any responsibility for, the accuracy or completeness of the statements in the Registration Statement and the Prospectus (and any amendment or supplement thereto), such counsel has participated in the preparation of the Registration Statement and the Prospectus, including review and discussion of the contents thereof, and nothing has come to the attention of such counsel that has caused it to believe that the Registration Statement, at the time the Registration Statement became effective or the Prospectus, as of its date and as of the Closing Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading or that any amendment or supplement to the Prospectus, as of the Closing Date, contained an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading (it being understood that such counsel need express no view with respect to the financial statements and the notes thereto and the schedules and other financial and statistical data included in, or omitted from, the Registration Statement or the Prospectus (or any amendment or supplement thereto)).

In rendering such opinion, such counsel may limit such opinion to matters involving the application of the laws of The Commonwealth of Massachusetts and the United States. To the extent they deem proper and to the extent specified in such opinion, such counsel may rely, as to matters involving the application of laws of The Commonwealth of Massachusetts, upon the opinion of Bingham McCutchen LLP or other counsel of good standing whom they believe to be reliable and who are satisfactory to the Underwriters; provided that (X) such reliance is expressly authorized by the opinion so relied upon and a copy of each such opinion is delivered to the Underwriters and is, in form and substance, satisfactory to them and their counsel and (Y) Vedder, Price, Kaufman & Kammholz, P.C. states in their opinion that they believe that they and the Underwriters are justified in relying thereon. References to the Prospectus in this paragraph (b) shall also include any supplements thereto at the Closing Date.

23

8. Reimbursement of Underwriters' Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 7 hereof is not satisfied or because of any refusal, inability or failure on the part of the Fund or the Adviser to perform any agreement herein or comply with


26

any provision hereof other than by reason of a default by any of the Underwriters, the Fund will reimburse the Underwriters severally through Citigroup Global Markets Inc. on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

9. Indemnification and Contribution. (a) The Fund and the Adviser, jointly and severally, agree to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several (including reasonable costs of investigation), to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Prospectus, any Preliminary Prospectus, any Preliminary Prospectus, any sales material (or any amendment or supplement to any of the foregoing), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus, any Preliminary Prospectus or any sales material (or any amendment or supplement to any of the foregoing), in light of the circumstances under which they were made) not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Fund will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Fund by or on behalf of any Underwriter through the Representatives specifically for inclusion therein; provided, further, that the foregoing indemnity with respect to the Registration Statement, the Prospectus or any Preliminary Prospectus (or any amendment or supplement to any of the foregoing) shall not inure to the benefit of any Underwriter from whom the person asserting any loss, claim, damage or liability purchased Securities, if it is shown that a copy of the Prospectus, as then amended or supplemented, which would have cured any defect giving rise to such loss, claim, damage or liability was not sent or delivered to such person by or on behalf of such Underwriter, if required by law to be so delivered to, at or prior to the confirmation of the sale of such Securities to such person and such Prospectus, amendments and supplements have been provided by the Fund to the Underwriters in the requisite quantity and on a timely basis to permit proper delivery. This indemnity agreement will be in addition to any liability which the Fund or the Adviser may otherwise have.

(a) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Fund and the Adviser, each of its directors, trustees, each of its officers who signs the Registration Statement, and each person who controls the Fund or the Adviser within the meaning of the Act or the Exchange Act, to the same extent as the indemnity from the Fund and the Adviser, to each Underwriter as set forth in Section 9(a) hereof, but only with respect to written information relating to such Underwriter furnished to the Fund by or on behalf of such Underwriter specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Fund and the Adviser acknowledge that the names of the underwriters and


27

numbers of Securities listed opposite such names in the first paragraph under the caption "Underwriting" in the Prospectus, constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus or the Prospectus.

(b) Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 9, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(c) In the event that the indemnity provided in paragraph (a) or (b) of this Section 9 is unavailable to or insufficient to hold harmless an indemnified party for any reason, then the Fund, the Adviser and the Underwriters shall contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Fund, the Adviser and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Fund and the Adviser on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the


28

offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Fund, the Adviser and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Fund and the Adviser on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Fund and the Adviser shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Fund and the Adviser, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Fund or the Adviser on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Fund, the Adviser and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (f), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 9, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Fund or the Adviser within the meaning of either the Act or the Exchange Act, each officer of the Fund and the Adviser who shall have signed the Registration Statement and each director of the Fund and the Adviser shall have the same rights to contribution as the Fund and the Adviser, subject in each case to the applicable terms and conditions of this paragraph (c). The Underwriters' obligations to contribute pursuant to this Section 9 are several in proportion to the respective aggregate number of Securities set forth opposite their names in Schedule I (or such numbers of Securities increased as set forth in Section 10 hereof) and not joint.

(d) Any losses, claims, damages or liabilities for which an indemnified party is entitled to indemnification or contribution under this
Section 9 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 9 and the representations and warranties of the Fund and the Adviser set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Fund, the Adviser or their shareholders, trustees, directors, managers, members or officers or any person controlling the Fund or the Adviser (control to be determined within the meaning of the Act or the Exchange Act), (ii) acceptance of any Securities and payment therefor hereunder and (iii) any termination of this Agreement. A successor to any Underwriter or to the Fund, the Adviser or their shareholders, trustees, directors, managers, members or officers or any person controlling any Underwriter, the Fund or the Adviser shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 9.


29

10. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the aggregate amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Underwriters or in such other proportion as you may specify in accordance with the Citigroup Global Markets Inc. Master Agreement Among Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Fund. In the event of a default by any Underwriter as set forth in this
Section 10 which does not result in a termination of this Agreement, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Underwriters shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Fund and any nondefaulting Underwriter for damages occasioned by its default hereunder. The term "Underwriter" as used in this Agreement includes, for all purposes of this Agreement, any party not listed in Schedule I hereto who, with your approval and the approval of the Fund, purchases Firm Securities which a defaulting Underwriter agreed, but failed or refused, to purchase.

11. Termination. This Agreement shall be subject to termination in the absolute discretion of the Underwriters, without liability on the part of the Underwriters to the Fund or the Adviser, by notice given to the Fund or the Adviser prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in the Fund's Common Shares shall have been suspended by the Commission or the AMEX or trading in securities generally on the AMEX shall have been suspended or limited or minimum prices shall have been established on the AMEX, (ii) a commercial banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of Citigroup Global Markets Inc., impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Prospectus (exclusive of any supplement thereto). Notice of such termination may be given to the Fund or the Adviser by telegram, facsimile or telephone and shall be subsequently confirmed by letter.

12. Representations and Indemnities to Survive. The provisions of Sections 8 and 9 hereof shall survive the termination or cancellation of this Agreement.

13. Miscellaneous. Except as otherwise provided in Sections 6, 10 and 11 hereof, notice given pursuant to any provision of this Agreement shall be in writing and shall be delivered (a) if to the Fund or the Adviser, c/o Nuveen Investments at 333 West Wacker Drive,

FORM OF

MASTER SELECTED DEALER AGREEMENT

July 1, 1999

Ladies and Gentlemen:

In connection with registered public offerings of securities for which we are acting as manager or co-manager of an underwriting syndicate or unregistered offerings of securities for which we are acting as manager or co-manager of the initial purchasers, you may be offered the right as a selected dealer to purchase as principal a portion of such securities. This will confirm our mutual agreement as to the general terms and conditions applicable to your participation in any such selected dealer group.

1. APPLICABILITY OF THIS AGREEMENT. The terms and conditions of this Agreement shall be applicable to any offering of securities ("Securities"), whether pursuant to a registration statement filed under the Securities Act of 1933, as amended (the "Securities Act"), or exempt from registration thereunder, in respect of which Salomon Smith Barney Inc. (acting for its own account or for the account of any underwriting or similar group or syndicate) is responsible for managing or otherwise implementing the sale of the Securities to selected dealers ("Selected Dealers") and has expressly informed you that such terms and conditions shall be applicable. Any such offering of Securities to you as a Selected Dealer is hereinafter called an "Offering". In the case of any Offering where we are acting for the account of any underwriting or similar group or syndicate ("Underwriters"), the terms and conditions of this Agreement shall be for the benefit of, and binding upon, such Underwriters, including, in the case of any Offering where we are acting with others as representatives of Underwriters, such other representatives.

2. CONDITIONS OF OFFERING; ACCEPTANCE AND PURCHASES. Any Offering will be subject to delivery of the Securities and their acceptance by us and any other Underwriters, may be subject to the approval of all legal matters by counsel and the satisfaction of other conditions, and may be made on the basis of reservation of Securities or an allotment against subscription. We will advise you by telecopy, telex or other form of written communication ("Written Communication", which term, in the case of any Offering described in Section 3(a) or 3(b) hereof, may include a prospectus or offering circular) of the particular method and supplementary terms and conditions (including, without limitation, the information as to prices and the offering date referred to in
Section 3(c) hereof) of any Offering in which you are invited to participate. To the extent such supplementary terms and conditions are inconsistent with any provision herein, such terms and conditions shall supersede any such provision. Unless otherwise indicated in any such Written Communication, acceptances and other communications by you with respect to an Offering should be sent to the appropriate Syndicate


Department of Salomon Smith Barney Inc. We may close the subscription books at any time in our sole discretion without notice, and we reserve the right to reject any acceptance in whole or in part.

Unless notified otherwise by us, Securities purchased by you shall be paid for on such date as we shall determine, on one day's prior notice to you, by wire transfer payable in immediately available funds to the order of Salomon Smith Barney Inc., in an amount equal to the Public Offering Price (as hereinafter defined) or, if we shall so advise you, at such Public Offering Price less the Concession (as hereinafter defined). If Securities are purchased and paid for at such Public Offering Price, such Concession will be paid after the termination of the provisions of Section 3(c) hereof with respect to such Securities. Unless notified otherwise by us, payment for and delivery of Securities purchased by you shall be made through the facilities of The Depository Trust Company, if you are a member, unless you have otherwise notified us prior to the date specified in a Written Communication to you from us or, if you are not a member, settlement may be made through a correspondent who is a member pursuant to instructions which you will send to us prior to such specified date.

3. REPRESENTATIONS, WARRANTIES AND AGREEMENTS.

(a) REGISTERED OFFERINGS. In the case of any Offering of Securities which are registered under the Securities Act ("Registered Offering"), we will make available to you as soon as practicable after sufficient copies are made available to us by the issuer of the Securities such number of copies of each preliminary prospectus and of the final prospectus relating thereto as you may reasonably request for the purposes contemplated by the Securities Act and the Securities Exchange Act of 1934, as amended (the "Exchange Act") and the applicable rules and regulations of the Securities and Exchange Commission thereunder.

You represent and warrant that you are familiar with Rule 15c2-8 under the Exchange Act relating to the distribution of preliminary and final prospectuses and agree that you will comply therewith. You agree to make a record of your distribution of each preliminary prospectus and when furnished with copies of any revised preliminary prospectus, you will promptly forward copies thereof to each person to whom you have theretofore distributed a preliminary prospectus.

You agree that in purchasing Securities in a Registered Offering you will rely upon no statement whatsoever, written or oral, other than the statements in the final prospectus delivered to you by us. You will not be authorized by the issuer or other seller of Securities offered pursuant to a prospectus or by any Underwriters to give any information or to make any representation not contained in the prospectus in connection with the sale of such Securities.

(b) OFFERINGS PURSUANT TO OFFERING CIRCULAR. In the case of any Offering of Securities, other than a Registered Offering, which is made pursuant to an offering circular or other document comparable to a prospectus in a Registered Offering, we will make available to you as soon as practicable after sufficient copies are made available to us by the issuer of the Securities such number of copies of each preliminary offering circular and of the final offering circular relating thereto as you may reasonably request. You agree that you will comply with applicable Federal, state and other laws, and the applicable rules and regulations of any regulatory body promulgated thereunder,

2

governing the use and distribution of offering circulars by brokers or dealers.

You agree that in purchasing Securities pursuant to an offering circular you will rely upon no statements whatsoever, written or oral, other than the statements in the final offering circular delivered to you by us. You will not be authorized by the issuer or other seller of Securities offered pursuant to an offering circular or by any Underwriters to give any information or to make any representation not contained in the offering circular in connection with the sale of such Securities.

(c) OFFER AND SALE TO THE PUBLIC. The Offering of Securities is made subject to the conditions referred to the prospectus or offering circular relating to the Offering and to the terms and conditions set forth in this Agreement. With respect to any Offering of Securities, we will inform you by a Written Communication of the public offering price, the selling concession, the reallowance (if any) to dealers and the time when you may commence selling Securities to the public. After such public offering has commenced, we may change the public offering price, the selling concession and the reallowance to dealers. The offering price, selling concession and reallowance (if any) to dealers at any time in effect with respect to an Offering are hereinafter referred to, respectively, as the "Public Offering Price", the "Concession" and the "Reallowance". With respect to each Offering of Securities, until the provisions of this Section 3(c) shall be terminated pursuant to Section 4 hereof, you agree to offer Securities to the public only at the Public Offering Price, except that if a Reallowance is in effect, a Reallowance from the Public Offering Price not in excess of such Reallowance may be allowed as consideration for services rendered in distribution to dealers who are actually engaged in the investment banking or securities business who are either members in good standing of the NASD who agree to abide by the applicable rules of the NASD (see
Section 3(e) below) or foreign banks, dealers or institutions not eligible for membership in the NASD who represent to you that they will promptly reoffer such Securities at the Public Offering Price and will abide by the conditions with respect to foreign banks, dealers and institutions set forth in Section 3(e) hereof.

(d) OVER-ALLOTMENT; STABILIZATION; UNSOLD ALLOTMENTS. We may, with respect to any Offering, be authorized to over-allot in arranging sales to Selected Dealers, to purchase and sell Securities for long or short account and to stabilize or maintain the market price of the Securities. You agree that upon our request at any time and from time to time prior to the termination of the provisions of Section 3(c) hereof with respect to any Offering, you will report to us the amount of Securities purchased by you pursuant to such Offering which then remain unsold by you and will, upon our request at any such time, sell to us for our account or the account of one or more Underwriters such amount of such unsold Securities as we may designate at the Public Offering Price less an amount to be determined by us not in excess of the Concession. If, prior to the later of (a) the termination of the provisions of Section 3(c) hereof with respect to any Offering, or (b) the covering by us of any short position created by us in connection with such Offering for our account or the account of one or more Underwriters, we purchase or contract to purchase for our account or the account of one or more Underwriters in the open market or otherwise any Securities purchased by you under this Agreement as part of such Offering, you agree to pay us on demand for the account of the Underwriters an amount equal to the Concession with respect to such Securities (unless you shall have purchased such Securities pursuant to Section 2 hereof at the Public Offering Price and you have not received or been credited with any Concession, in which case we shall not be obligated to pay such Concession to you pursuant to Section 2) plus transfer taxes

3

and broker's commissions or dealer's mark-up, if any, paid in connection with such purchase or contract to purchase.

(e) NASD. You represent and warrant that you are actually engaged in the investment banking or securities business and either are a member in good standing of the NASD or, if you are not such a member, you are a foreign bank, dealer or institution not eligible for membership in the NASD which agrees to make no sales within the United State, its territories or its possessions or to persons who are citizens thereof or residents therein, and in making other sales to comply with the NASD's interpretation with respect to free-riding and withholding. You further represent, by your participation in an Offering, that you have provided to us all documents and other information required to be filed with respect to you, any related person or any person associated with you or any such related person pursuant to the supplementary requirements of the NASD's interpretation with respect to review of corporate financing as such requirements relate to such Offering.

You agree that, in connection with any purchase or sale of the Securities wherein a selling concession, discount or other allowance is received or granted, you will (a) if you are a member of the NASD, comply with all applicable interpretive material ("IM") and Conduct Rules of the NASD, including, without limitation, IM 2110-1 (relating to Free-Riding and Withholding) and Conduct Rule 2740 (relating to Selling Concessions, Discounts and Other Allowances) or (b) if you are a foreign bank or dealer or institution not eligible for such membership, comply with IM 2110-1 and with Conduct Rules 2730 (relating to Securities Taken in Trade), 2740 (relating to Selling Concessions) and 2750 (relating to Transactions With Related Persons) as though you were such a member and Conduct Rule 2420 (relating to Dealing with Non-Members) as it applies to a non-member broker or dealer in a foreign country.

You further agree that, in connection with any purchase of securities from us that is not otherwise covered by the terms of this Agreement (whether we are acting as manager, as member of an underwriting syndicate or a selling group or otherwise), if a selling concession, discount or other allowance is granted to you, clauses (a) and (b) of the preceding paragraph will be applicable.

(f) RELATIONSHIP AMONG UNDERWRITERS AND SELECTED DEALERS. We may buy Securities from or sell Securities to any Underwriter or Selected Dealer and, with our consent, the Underwriters (if any) and the Selected Dealers may purchase Securities from and sell Securities to each other at the Public Offering Price less all or any part of the Concession. We shall have full authority to take such action as we deem advisable in all matters pertaining to any Offering under this Agreement. You are not authorized to act as agent for us, any Underwriter or the issuer or other seller of any Securities in offering Securities to the public or otherwise. Neither we nor any Underwriter shall be under any obligation to you except for obligations assumed hereby or in any Written Communication from us in connection with any Offering. Nothing contained herein or in any Written Communication from us shall constitute the Selected Dealers an association or partners with us or any Underwriter or with one another. If the Selected Dealers, among themselves or with the Underwriters, should be deemed to constitute a partnership for Federal income tax purposes, then you elect to be excluded from the application of Subchapter K, Chapter 1, Subtitle A of the Internal Revenue Code of 1986 and agree not to take any position inconsistent with that election. You authorize us, in our discretion, to execute and file on your behalf such evidence of that election as may

4

be required by the Internal Revenue Service. In connection with any Offering you shall be liable for your proportionate amount of any tax, claim, demand or liability that may be asserted against you alone or against one or more Selected Dealers participating in such Offering, or against us or the Underwriters, based upon the claim that the Selected Dealers, or any of them constitute an association, an unincorporated business or other entity, including, in each case, your proportionate amount of any expense incurred in defending against any such tax, claim, demand or liability.

(g) BLUE SKY LAWS. Upon application to us, we shall inform you as to any advice we have received from counsel concerning the jurisdictions in which Securities have been qualified for sale or are exempt under the securities or blue sky laws of such jurisdictions, but we do not assume any obligation or responsibility as to your right to sell Securities in any such jurisdiction.

(h) COMPLIANCE WITH LAW. You agree that in selling Securities pursuant to any Offering (which agreement shall also be for the benefit of the issuer or other seller of such Securities), you will comply with all applicable laws, rules and regulations, including the applicable provisions of the Securities Act and the Exchange Act, the applicable rules and regulations of the Securities and Exchange Commission thereunder, the applicable rules and regulations of the NASD, the applicable rules and regulations of any securities exchange or other regulatory authority having jurisdiction over the Offering and the applicable laws, rules and regulations specified in Section 3(b) hereof. Without limiting the foregoing, (a) you agree that, at all times since you were invited to participate in an Offering of Securities, you have complied with the provisions of Regulation M applicable to such Offering, in each case after giving effect to any applicable exemptions and (b) you represent that your incurrence of obligations hereunder in connection with any Offering of Securities will not result in the violation by you of Rule 15c3-1 under the Exchange Act, if such requirements are applicable to you.

4. TERMINATION; SUPPLEMENTS AND AMENDMENTS. This Agreement shall continue in full force and effect until terminated by a written instrument executed by each of the parties hereto. This Agreement may be supplemented or amended by us by written notice thereof to you, and any such supplement or amendment to this Agreement shall be effective with respect to any Offering to which this Agreement applies after the date of such supplement or amendment. Each reference to "this Agreement" herein shall, as appropriate, be to this Agreement as so amended and supplemented. The terms and conditions set forth in
Section 3(c) hereof with regard to any Offering will terminate at the close of business on the 30th day after the commencement of the public offering of the Securities to which such Offering relates, but in our discretion may be extended by us for a further period not exceeding 30 days and in our discretion, whether or not extended, may be terminated at any earlier time.

5. SUCCESSORS AND ASSIGNS. This Agreement shall be binding on, and inure to the benefit of, the parties hereto and other persons specified in Section 1 hereof, and the respective successors and assigns of each of them.

6. GOVERNING LAW.

FORM OF:

NUVEEN EXCHANGE-TRADED FUNDS

MASTER SELECTED DEALER AGREEMENT

[DATED]

Dear Ladies and Gentlemen:

In connection with public offerings of securities ("Securities") of registered investment companies sponsored by Nuveen Investments ("Nuveen") which are underwritten by a group of underwriters ("Underwriters") which are represented by Nuveen alone or in conjunction with other firms (the "Representatives"), you (a "Dealer") may be offered from time to time the opportunity to purchase a portion of such securities, as a principal, at a discount from the public offering price representing a selling concession or reallowance granted as consideration for services rendered in the distribution of such securities, subject to the terms and conditions of this Agreement.

1. General. (a) This Agreement sets forth the general terms, conditions and representations applicable to any such purchase. These general terms, conditions and representations may be modified, amended or supplemented in connection with an offering of Securities by telegram, telex, facsimile transmission or other written form (electronic or otherwise) of communication of Nuveen or other Representative of the Underwriters of such offering (any communication in any such form being herein referred to as a "written communication") to you in connection with such offering. This Agreement shall become effective with respect to your participation in an offering of Securities upon your acceptance of any reservation of any such Securities, as a Dealer. Such acceptance shall constitute your acceptance of this Agreement as modified, amended or supplemented by any such written communication.

(b) As used herein, the term "Agreement" shall mean this Agreement and, after receipt by you of written notice thereof, any amendment or supplement hereto, plus any additional or supplementary terms, conditions and representations contained in the prospectus relating to the offering of Securities or any other written communication to you from Nuveen or any other Representative of the Underwriters of any offering of securities. This Agreement shall constitute a binding agreement between you and Nuveen, individually, and, in respect of a public offering of Securities, Nuveen and the other Representatives of the Underwriters of such offering on whose behalf Nuveen is acting.

(c) This Agreement supersedes any prior understanding you have with Nuveen with respect to the subject matter hereof.


2. Sales to Selected Dealers. For any specific offering, we will advise you by telegram of the method and terms of offering, the time of the release of the Securities for sale to the public, the initial offering price, the selling concession, the portion of the selling concession allowable to certain dealers (the "reallowance"), the time at which subscription books will be opened, the amount, if any, of Securities reserved for purchase by Dealers and the period of reservation. Subscription books may be closed by us at any time in our discretion without notice, and the right is reserved to reject any subscription in whole or in part. Notification of allotments against the rejections of subscriptions will be made as promptly as practicable. In purchasing Securities, you must rely only on the prospectus, and on no other statements whatsoever, written or oral.

3. Offering Provisions. Upon receipt of the telegram or letter referred to in Section 2 hereof, promptly on the date set forth in such telegram for release of the Securities for sale to the public, you will reoffer the Securities purchased by you hereunder, subject to receipt and acceptance of the Securities by the Underwriters, and upon the other terms, conditions and representations set forth herein and in the prospectus relating to such Securities. Securities purchased hereunder are to be offered to the public at the initial public offering price set forth in the prospectus, except that if a reallowance is in effect, a reallowance from the public offering price not in excess of such reallowance may be allowed by you but only to dealers who are actually engaged in the investment banking or securities business, who execute the written agreement prescribed by Rule 2740(c) of the Rules of Conduct of the National Association of Securities Dealers, Inc. ("NASD") and who are members in good standing of the NASD or are foreign dealers, not eligible for membership in the NASD, who, in each case, represent to you that they will promptly reoffer such Securities to the public at the initial public offering price set forth in the prospectus and will abide by the conditions with respect to foreign brokers and dealers set forth in the first paragraph of Section 6 hereof.

If prior to the completion of a distribution of the Securities in an offering, directly or indirectly in connection with their activities under this agreement, Nuveen or an Underwriter of the offering purchases on the open market any Securities purchased by you under this Agreement as part of the offering, you agree to pay Nuveen or the lead Representative of the Underwriters of the offering on demand an amount equal to the concession with respect to the Securities, plus, as applicable, transfer taxes, broker's commission, or dealer's markups, if any, paid in connection with such transactions. Alternatively, Nuveen or the Representatives of the Underwriters of the offering may withhold payment for a period of time of, or determine not to pay, all or any part of the concession with respect to the Securities so received. You will advise Nuveen or any other Representative from time to time at our request, of the number of Securities purchased by you hereunder remaining unsold and you agree to sell to us, at our request, for the account of one or more of the Underwriters, such number of such unsold Securities as we may designate, at the initial offering price less an amount to be determined by us, not in excess of the full concession.

4. Delivery and Payment. Payment for and delivery of Securities purchased by you hereunder will be made through the facilities of the Depository Trust Company, if you are a member, or, if you are not a member, settlement may be made through a correspondent who is a member pursuant to instructions which you will send to us prior to such specified date. At the discretion of Nuveen or a Representative of the Underwriters of the offering, we may require you to pay the full public offering price for any offering of Securities. If you are called upon to pay the full public offering price for the Securities purchased by you the concession will be paid to


you, less any amounts charged to your account pursuant to Section 3 above, after termination of this Agreement.

5. Termination. This Agreement shall continue in full force and effect until terminated by either party by five days' written notice to the other; provided, that if this Agreement has become effective with respect to any offering of Securities, this Agreement may not be terminated by you with respect to such offering. It shall remain in full force and effect as to such offering. Notwithstanding any distribution and settlement of accounts, you shall be liable for the proper proportion of any transfer tax or other liability which may be asserted against the Representatives or any of the Underwriters or Dealers based upon the claim that the Dealers, or any of them, constitute a partnership, an association, an unincorporated business or other separate entity.

6. Position of Selected Dealers and Underwriters. You represent that you are actually engaged in the investment banking or securities business and are a member in good standing of the NASD or that you are a foreign dealer, not eligible for membership in the NASD, which agrees not to offer or sell any Securities in, or to persons who are nationals or residents of, the United States of America. In making sales of Securities, if you are such a member, you agree to comply with all applicable rules of the NASD, including, without limitation, IM 2110-1 (the NASD's Interpretation with Respect to Free-Riding and Withholding) and Rules 2740 and 2750 of the NASD's Rules of Conduct, or, if you are a foreign dealer, you agree to comply with such Interpretation and Rules 2730, 2740 and 2750 of such Rules of Conduct as though you were such a member, and with Rule 2420 as that Rule applies to a non-member broker or dealer in a foreign country. You also confirm that you have complied and will comply with the prospectus delivery requirements of Rule 15c2-8 under the Securities Exchange Act of 1934, as amended including Rule 15c2-8(b) which requires all participating dealers to distribute a copy of the preliminary prospectus relating to the offering of Securities to each person to whom they expect to confirm a sale of the Securities not less than 48 hours prior to the time they expect to mail such confirmation. You are not authorized to give any information or make any representations with respect to an offering of Securities other than those contained in the prospectus for the offering, or to act as agent for the issuer, any Underwriter, Representative or Nuveen.

Neither Nuveen, individually or as Representative of the Underwriters, nor any of the Representatives or Underwriters shall be under any liability to you, except for obligations expressly assumed in this Agreement and any liabilities under the Securities Act of 1933, as amended. No obligations on the part of Nuveen will be implied or inferred herefrom. All communications to Nuveen relating to the subject matter of this Agreement should be addressed to Nuveen Investments, 333 W. Wacker Drive, Chicago, Illinois 60606 (Attention:
Debbie Taylor), and any notices to you shall be deemed to have been duly given if mailed or telegraphed to you at such address as you shall indicate on the last page of this Agreement.

7. Blue Sky Matters. Neither Nuveen, individually or as a Representative of the Underwriters, nor any of the Representatives or Underwriters will have any responsibility with respect to the right of any Dealer to sell Securities in any jurisdiction, notwithstanding any information we may furnish in that connection.


8. Indemnification. You agree to indemnify and hold harmless Nuveen and each Representative and Underwriter of an offering of Securities and each person, if any, who controls Nuveen or any such Representative or Underwriter within the meaning of Section 15 of the Securities Act of 1933, as amended or
Section 20 of the Securities Exchange Act of 1934, as amended, from and against any and all losses, claims, damages, liabilities and expenses, joint or several (including reasonable costs of investigation) (any of the foregoing being hereinafter referred to individually as a "Loss" and collectively, as "Losses") suffered or incurred by any such indemnified person arising out of or in connection with such offering for or on account of or arising from or in connection with (i) any violation by you of any law, rule or regulation (including any rule of any self-regulatory organization) or (ii) any breach of any representation, warranty, covenant or agreement contained in this Agreement. The foregoing indemnity agreement shall be in addition to any liability which you may otherwise have.

9. Procedures Relating to Indemnification. (a) An indemnified person under Section 8 of this Agreement (the "Indemnified Party") shall give written notice to you of any Loss in respect of which you have a duty to indemnify such Indemnified Party under Section 8 of this Agreement (a "Claim"), specifying in reasonable detail the nature of the Loss for which indemnification is sought, except that any delay or failure so to notify you shall only relieve you of your obligations hereunder to the extent, if at all, that you are actually prejudiced by reason of such delay or failure.

(b) If a Claim results from any action, suit or proceeding brought or asserted against an Indemnified Party, you shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all fees and expenses. The Indemnified Party shall have the right to employ separate counsel in such action, suit or proceeding and participate in such defense thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless (i) you have agreed in writing to pay such fees and expenses, (ii) you have failed within a reasonable time to assume the defense and employ counsel or (iii) the named parties to any such action, suit or proceeding (including any impleaded parties) include both such Indemnified Party and you and such Indemnified Party shall have been advised by its counsel that representation of such Indemnified Party and you by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between you and the Indemnified Party (in which case you shall not have the right to assume the defense of such action, suit or proceeding on behalf of such Indemnified Party). It is understood, however, that you shall, in connection with any one action, suit or proceeding or separate but substantially similar or related actions, suits or proceedings in the same jurisdiction arising out of the same general allegations or circumstances be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such Indemnified Parties not having actual or potential differing interests with you or among themselves, which firm shall be designated in writing by the Representatives of the offering and that all such fees and expenses shall be reimbursed promptly as they are incurred. You shall not be liable for any settlement of any such action, suit or proceeding effected without your written consent, but if settled with such written consent or if there be a final judgment for the plaintiff in any such action, suit or proceeding, you agree to indemnify and hold harmless any Indemnified Party from and against any loss, liability, damage or expense by reason by such settlement or judgment.


(c) With respect to any Claim not within Paragraph (b) of Section 9 hereof, you shall have 20 days from receipt of notice from the Indemnified Party of such Claim within which to respond thereto. If you do not respond within such twenty-day period, you shall be deemed to have accepted responsibility to make payment and shall have no further right to contest the validity of such Claim. If you notify the Indemnified Party within such twenty-day period that you reject such Claim in whole or in part, the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party under applicable law.

10. Survival. The representations, warranties, covenants and agreements of the undersigned contained in this Agreement, including, without limitation, the indemnity agreements contained in Sections 8 and 9 hereof, shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Representative or Underwriter or any person controlling any Representative or Underwriter, or their directors or officers, (ii) acceptance of any Shares and payment therefor and (iii) any termination of this Agreement.

11. This Agreement shall be governed by the laws of the State of New York or the laws of such other state as indicated in a written communication to you by Nuveen with respect to any particular securities offering.

Please confirm your agreement to the foregoing by signing in the space provided below and returning to us the enclosed counterpart of this Agreement.

The term "PRELIMINARY OFFERING CIRCULAR" means any preliminary offering circular or memorandum, if any, or any other written preliminary materials authorized by the Issuer to be used in connection with such an Offering. As used herein, the terms "OFFERING CIRCULAR" and "PRELIMINARY OFFERING CIRCULAR" shall include the material, if any, incorporated by reference therein. We will either, as soon as practicable after the later of the date of the Invitation Wire or the date made available to us by the Issuer, furnish to you (or make available for your review in our office) a copy of any Preliminary Offering Circular or any proof or draft of the Offering Circular.

III. MANAGER'S AUTHORITY

3.1. AUTHORITY OF MANAGER TO DETERMINE FORM OF DOCUMENTS, TERMS OF OFFERING, ETC. You authorize the Manager to act as lead manager of the Offering of the Securities by the Underwriters (the "UNDERWRITERS' SECURITIES") or by the Issuer or Seller pursuant to delayed delivery contracts (the "CONTRACT SECURITIES"), if any, contemplated by the Underwriting Agreement. You authorize the Manager, on your behalf, (a) to determine the form of the Underwriting Agreement, (b) to execute and deliver the Underwriting Agreement to the Issuer, Guarantor or Seller, (c) to determine the form of any agreement or agreements between or among the syndicates participating in the International Offering of which the Offering is a part (each an "INTERSYNDICATE AGREEMENT"), and (d) to execute and deliver any such Intersyndicate Agreement. You authorize the Manager
(i) to exercise any Over-allotment Option for the purchase any of or all the Additional Securities for the accounts of the several Underwriters pursuant to the Underwriting Agreement, (ii) to agree, on your behalf and on behalf of the Co-Managers, to any addition to, change in or waiver of any provision of, or the termination of, the Underwriting Agreement or any Intersyndicate Agreement (other than an increase in the Purchase Price or in your Original Purchase Obligation to purchase Securities, in either case from that contemplated by the applicable AAU), (iii) to add or remove prospective Underwriters to or from the syndicate, (iv) to exercise, in the Manager's discretion, all the authority vested in the Manager in the Underwriting Agreement and (v) except as described below in this Section 3.1, to take any other action as may seem advisable to the Manager in respect of the Offering (including, without limitation, actions and communications with the Commission, the National Association of Securities Dealers, Inc. (the "NASD"), state blue sky or securities commissions, stock exchanges and other regulatory bodies or organizations). If, in accordance with the terms of the applicable AAU, the Offering of the Securities is at varying prices based on prevailing market prices or prices related to prevailing market

4

prices or at negotiated prices, you authorize the Manager to determine, on your behalf in the Manager's discretion, any Offering Price and the Fees and Commissions applicable to the Offering from time to time. You authorize the Manager on your behalf to arrange for any currency transactions (including forward and hedging currency transactions) as the Manager deems necessary to facilitate settlement of the purchase of the Securities, but you do not authorize the Manager on your behalf to engage in any other forward or hedging transactions in connection with the Offering unless such transactions are specified in an applicable AAU or are otherwise consented to by you. You further authorize the Manager, subject to the provisions of Section 1.2 hereof, (i) to vary the offering terms of the Securities in effect at any time, including, if applicable, the Offering Price and Fees and Commissions set forth in the applicable AAU, (ii) to determine, on your behalf, the Purchase Price and (iii) to increase or decrease the number, amount or percentage of Securities being offered. Notwithstanding the foregoing provisions of this Section 3.1, the Manager shall notify the Underwriters, prior to the signing of the Underwriting Agreement, of any provision in the Underwriting Agreement that could result in an increase in the amount or percentage of Firm Securities set forth opposite each Underwriter's name in the Underwriting Agreement by more than 25% (or such other percentage as shall have been specified in the applicable Invitation Wire or otherwise consented to by you) as a result of the failure or refusal of another Underwriter or Underwriters to perform its or their obligations thereunder.

3.2. OFFERING DATE. The Offering is to be made as soon after the Underwriting Agreement is entered into by the Issuer, Guarantor or Seller and the Manager as in the Manager's judgment is advisable, on the terms and conditions set forth in the Prospectus or the Offering Circular, as the case may be, and the applicable AAU. You agree not to sell any Securities prior to the time the Manager releases such Securities for sale to purchasers. The date on which such Securities are released for sale is referred to herein as the "OFFERING DATE".

3.3. ADVERTISING; SUPPLEMENTAL OFFERING MATERIAL. Any public advertisement of the Offering shall be made by the Manager on behalf of the Underwriters on such date as the Manager shall determine. You agree not to advertise the Offering prior to the date of the Manager's advertisement thereof without the Manager's consent. If the offering is made in whole or in part in reliance on Rule 144A (or upon another exemption from registration), you agree not to engage in any general solicitation and to abide by any other restrictions in the AAU or the Underwriting Agreement in connection therewith relating to any advertising or publicity. Any advertisement you may make of the Offering after such date will be your own responsibility and at your own expense and risk. In addition to your agreement to comply with restrictions on the Offering pursuant to Sections 10.10 and 10.11 hereof, you also agree that you will not, in connection with the offer and sale of the Securities in the Offering, without the consent of the Manager, give to any prospective purchaser of the Securities or other person not in your employ any written information concerning the Offering, the Issuer, the Guarantor or the Seller, other than information contained in any Preliminary Prospectus, Prospectus, Preliminary Offering Circular or Offering Circular or in any computational materials ("COMPUTATIONAL MATERIALS") or other offering materials

5

prepared by or with the consent of the Manager for use by the Underwriters in connection with the Offering and, in the case of a Registered Offering, filed with the Commission or the NASD, as applicable (the "SUPPLEMENTAL OFFERING MATERIALS"). You further agree to cease distribution of any COMPUTATIONAL MATERIALS on the Offering Date.

3.4. INSTITUTIONAL AND RETAIL SALES. You authorize the Manager to sell to institutions or retail purchasers such Securities purchased by you pursuant to the Underwriting Agreement as the Manager shall determine. The Selling Concession on any such sales shall be credited to the accounts of the Underwriters as the Manager shall determine.

3.5. SALES TO DEALERS. You authorize the Manager to sell to Dealers (as defined below) such Securities purchased by you pursuant to the Underwriting Agreement as the Manager shall determine. A "DEALER" shall be a person who is (a) a broker or dealer (as defined in the By-Laws of the NASD) actually engaged in the investment banking or securities business and (i) a member in good standing of the NASD or (ii) a foreign bank, broker, dealer or other institution not eligible for membership in the NASD that, in the case of either clause (a)(i) or (a)(ii), makes the representations and agreements applicable to such institutions contained in Section 10.6 hereof or (b) in the case of Offerings of Securities that are exempt securities under Section 3(a)(12) of the Securities Exchange Act of 1934, as amended (the "1934 ACT"), and such other Securities as from time to time may be sold by a "bank" (as defined in Section 3(a)(6) of the 1934 Act (a "BANK")), a Bank that is not a member of the NASD and that makes the representations and agreements applicable to such institutions contained in Section 10.6 hereof. If the price for any such sales by the Manager to Dealers exceeds an amount equal to the Offering Price less the Selling Concession set forth in the applicable AAU, the amount of such excess, if any, shall be credited to the accounts of the Underwriters as the Manager shall determine.

3.6. DIRECT SALES. The Manager will advise you promptly, on the date of the Offering, as to the Securities purchased by you pursuant to the Underwriting Agreement that you shall retain for direct sale. At any time prior to the termination of the applicable AAU, any such Securities that are held by the Manager for sale but not sold, may, on your request and at the Manager's discretion, be released to you for direct sale, and Securities so released to you shall no longer be deemed held for sale by the Manager. You may allow, and Dealers may reallow, a discount on sales to Dealers in an amount not in excess of the Reallowance set forth in the applicable AAU. You may not purchase Securities from, or sell Securities to, any other Underwriter or Dealer at any discount or concession other than the Reallowance, except with the consent of the Manager.

3.7. RELEASE OF UNSOLD SECURITIES. From time to time prior to the termination of the applicable AAU, on the request of the Manager, you shall advise the Manager of the amount of Securities remaining unsold which were retained by or released to you for direct sale and of the amount of Securities and Other Securities (as defined below) purchased for your account remaining unsold which were delivered to

6

you pursuant to Article V hereof or pursuant to any Intersyndicate Agreement, and, on the request of the Manager, you shall release to the Manager any such Securities and Other Securities remaining unsold (i) for sale by the Manager to institutions, Dealers or retail purchasers, (ii) for sale by the Issuer or Seller pursuant to delayed delivery contracts or (iii) if, in the Manager's opinion, such Securities or Other Securities are needed to make delivery against sales made pursuant to Article V hereof or any Intersyndicate Agreement.

3.8. INTERNATIONAL OFFERINGS. In the case of an International Offering, you authorize the Manager (i) to make representations on your behalf as set forth in any Intersyndicate Agreement or Underwriting Agreement and (ii) to purchase or sell for your account pursuant to the Intersyndicate Agreement
(a) Securities, (b) any other securities of the same class and series, or any securities into which the Securities may be converted or for which the Securities may be exchanged or exercised and (c) any other securities designated in the applicable AAU or applicable Intersyndicate Agreement (the securities referred to in clauses (b) and (c) above being referred to collectively as the "OTHER SECURITIES").

IV. DELAYED DELIVERY CONTRACTS

4.1. ARRANGEMENTS FOR SALES. You agree that arrangements for sales of Contract Securities will be made only through the Manager acting either directly or through Dealers (including Underwriters acting as Dealers), and you authorize the Manager to act on your behalf in making such arrangements. The aggregate amount of Securities to be purchased by the several Underwriters shall be reduced by the respective amounts of Contract Securities attributed to such Underwriters as hereinafter provided. Subject to the provisions of Section 4.2, the aggregate amount of Contract Securities shall be attributed to the Underwriters as nearly as practicable in their respective Underwriting Percentages, except that, as determined by the Manager in its discretion, (i) Contract Securities directed and allocated by a purchaser to specific Underwriters shall be attributed to such Underwriters and (ii) Contract Securities for which arrangements have been made for sale through Dealers shall be attributed to each Underwriter approximately in the proportion that Securities of such Underwriter held by the Manager for sales to Dealers bear to all Securities so held. The fee with respect to Contract Securities payable to the Manager for the accounts of the Underwriters pursuant to the Underwriting Agreement shall be credited to the accounts of the respective Underwriters in proportion to the Contract Securities attributed to such Underwriters pursuant to the provisions of this Section 4.1, less, in the case of each Underwriter, the concession to Dealers on Contract Securities sold through Dealers and attributed to such Underwriter.

4.2. EXCESS SALES. If the amount of Contract Securities attributable to an Underwriter pursuant to Section 4.1 would exceed such Underwriter's Original Purchase Obligation reduced by the amount of Underwriters' Securities sold by or on behalf of such Underwriter, such excess shall not be attributed to such Underwriter, and such Underwriter shall be regarded as having acted only as a Dealer with respect to, and shall receive only the concession to Dealers on, such excess.

7

V. PURCHASE AND SALE OF SECURITIES; FACILITATION OF DISTRIBUTION

5.1. PURCHASE AND SALE OF SECURITIES; FACILITATION OF DISTRIBUTION. In order to facilitate the distribution and sale of the Securities, you authorize the Manager to buy and sell Securities and any Other Securities, in addition to Securities sold pursuant to Article III hereof, in the open market or otherwise (including, without limitation, pursuant to any Intersyndicate Agreement), for long or short account, on such terms as it shall deem advisable, and to over-allot in arranging sales. Such purchases and sales and over-allotments shall be made for the accounts of the several Underwriters as nearly as practicable in their respective Underwriting Percentages or, in the case of an International Offering, such purchases and sales shall be for such accounts as set forth in the applicable Intersyndicate Agreement. Any securities which may have been purchased by the Manager for stabilizing purposes in connection with the Offering prior to the execution of the applicable AAU shall be treated as having been purchased pursuant to this Section 5.1 for the accounts of the several Underwriters or, in the case of an International Offering, for such accounts as are set forth in the applicable Intersyndicate Agreement. Your net commitment pursuant to the foregoing authorization shall not exceed at the close of business on any day an amount equal to 20% of your Underwriting Percentage of the aggregate initial Offering Price of the Firm Securities, it being understood that, in calculating such net commitment, the initial Offering Price shall be used with respect to the Securities so purchased or sold and, in the case of all Other Securities, shall be the purchase price thereof. Your net commitment for short account (i.e., "naked short") shall be calculated by assuming that all Securities that may be purchased upon exercise of any over-allotment option then exercisable are acquired (whether or not actually acquired) and, in the case of an International Offering, after giving effect to the purchase of any Securities or Other Securities that the Manager has agreed to purchase for your account pursuant to any applicable Intersyndicate Agreement. On demand you shall take up and pay for any Securities or Other Securities so purchased for your account and any Securities released to you pursuant to Section 3.7 hereof and you shall deliver to the Manager against payment any Securities or Other Securities so sold or over-allotted for your account or released to you. The Manager agrees to notify you if it engages in any stabilization transaction requiring reports to be filed pursuant to Rule 17a-2 under the 1934 Act and to notify you of the date of termination of stabilization. You agree not to stabilize or engage in any syndicate covering transaction (as defined in Rule 100 of Regulation M under the 1934 Act ("Regulation M")) in connection with the Offering without the prior consent of the Manager. You further agree to provide to Salomon Smith Barney any reports required of you pursuant to Rule 17a-2 not later than the date specified therein and you authorize Salomon Smith Barney to file on your behalf with the Commission any reports required by such Rule.

If the limitations of Rule 101 of Regulation M ("Rule 101") do not apply to you with respect to the Securities, Other Securities or other reference securities (as defined in Rule 100 of Regulation M) because they satisfy the exception for actively-traded

8

securities in subsection (c)(1) of Rule 101 or the exception for Rule 144A securities in subsection (b)(10) of Rule 101, you agree that promptly upon notice from the Manager (or, if later, at the time stated in the notice) you will comply with Rule 101 as though such exception were not available but the other provisions of Rule 101 (as interpreted by the Commission and after giving effect to any applicable exemptions) did apply. If the securities in question are NASDAQ securities (as defined in Rule 100 of Regulation M) you may engage in passive market making in accordance with Rule 103 of Regulation M (except that the daily net purchase volume limitation will not apply and the maximum displayed bid size shall be 5,000 shares excluding transactions effected in the SOES system) unless the notice from the Manager also states that passive market making is not permitted.

5.2. PENALTY WITH RESPECT TO SECURITIES REPURCHASED BY THE MANAGER. If pursuant to the provisions of Section 5.1 and prior to the termination of the Manager's authority to cover any short position incurred under the applicable AAU or such other date as the Manager shall specify in a Wire, either (A) the Manager purchases or contracts to purchase for the account of any Underwriter in the open market or otherwise any Securities which were retained by, or released to, you for direct sale or any Securities sold pursuant to Section 3.4 for which you received a portion of the Selling Concession set forth in the applicable AAU, or any Securities which may have been issued on transfer or in exchange for such Securities, and which Securities were therefore not effectively placed for investment or (B) if the Manager has advised you by Wire that trading in the Securities will be reported to the Manager pursuant to the "Initial Public Offering Tracking System" of The Depository Trust Company ("DTC") and the Manager determines, based on notices from DTC, that your customers sold an amount of Securities during any day that exceeds the amount previously notified to you by Wire, then you authorize the Manager either to charge your account with an amount equal to such portion of the Selling Concession set forth in the applicable AAU received by you with respect to such Securities or, in the case of clause (B), such Securities as exceed the amount specified in such Wire or to require you to repurchase such Securities or, in the case of clause (B), such Securities as exceed the amount specified in such Wire, at a price equal to the total cost of such purchase, including transfer taxes, accrued interest, dividends and commissions, if any.

5.3. COMPLIANCE WITH REGULATION M. You represent that, at all times since you were invited to participate in the Offering, you have complied with the provisions of Regulation M applicable to such Offering, in each case as interpreted by the Commission and after giving effect to any applicable exemptions. If you have been notified in a Wire that the Underwriters may conduct passive market making in compliance with Rule 103 of Regulation M in connection with the Offering, you represent that, at all times since your receipt of such Wire, you have complied with the provisions of such Rule applicable to such Offering, as interpreted by the Commission and after giving effect to any applicable exemptions.

5.4. STANDBY UNDERWRITINGS. You authorize the Manager in its discretion, at any time on, or from time to time prior to, the expiration of the conversion right of convertible securities identified in the applicable AAU in the case of securities

9

called for redemption, or the expiration of rights to acquire securities in the case of rights offerings, for which, in either case, standby underwriting arrangements have been made: (i) to purchase convertible securities or rights to acquire Securities for your account, in the open market or otherwise, on such terms as the Manager determines and to convert convertible securities or exercise rights so purchased; and (ii) to offer and sell the underlying common stock or depositary shares for your account, in the open market or otherwise, for long or short account (for purposes of such commitment, such common stock or depositary shares being considered the equivalent of convertible securities or rights), on such terms consistent with the terms of the Offering set forth in the Prospectus or Offering Circular as the Manager determines. On demand you shall take up and pay for any securities so purchased for your account or you shall deliver to the Manager against payment any securities so sold, as the case may be. During such period you may offer and sell the underlying common stock or depositary shares, but only at prices set by the Manager from time to time, and any such sales shall be subject to the Manager's right to sell to you the underlying common stock or depositary shares as above provided and to the Manager's right to reserve your Securities purchased, received or to be received upon conversion. You agree not to bid for, purchase, attempt to induce others to purchase, or sell, directly or indirectly, any convertible securities or rights or underlying common stock or depositary shares, provided, however, that no Underwriter shall be prohibited from (a) selling underlying common stock owned beneficially by such Underwriter on the day the convertible securities were first called for redemption, (b) converting convertible securities owned beneficially by such Underwriter on such date or selling underlying common stock issued upon conversion of convertible securities so owned, (c) exercising rights owned beneficially by such Underwriter on the record date for a rights offering or selling the underlying common stock or depositary shares issued upon exercise of rights so owned or (d) purchasing or selling convertible securities or rights or underlying common stock or depositary shares as a broker pursuant to unsolicited orders.

VI. PAYMENT AND SETTLEMENT

6.1. PAYMENT AND SETTLEMENT. You shall deliver to the Manager on the date and at the place and time specified in the applicable AAU (or on such later date and at such place and time as may be specified by the Manager in a subsequent Wire) the funds specified in the applicable AAU, payable to the order of Salomon Smith Barney Inc., for (i) an amount equal to the Offering Price plus (if not included in the Offering Price) accrued interest, amortization of original issue discount or dividends, if any, specified in the Prospectus or Offering Circular, less the applicable Selling Concession in respect of the Firm Securities to be purchased by you, (ii) an amount equal to the Offering Price plus (if not included in the Offering Price) accrued interest, amortization of original issue discount or dividends, if any, specified in the Prospectus or Offering Circular, less the applicable Selling Concession in respect of such of the Firm Securities to be purchased by you as shall have been retained by or released to you for direct sale as contemplated by Section 3.6 hereof or (iii) the amount set forth or indicated in the applicable AAU, as the Manager shall advise. You shall make similar payment as the Manager may direct for Additional Securities, if any, to be purchased by

IX. TERMINATION; INDEMNIFICATION

9.1. TERMINATION. Each AAU shall terminate at the close of business on the later of the date on which the Underwriters pay the Issuer or Seller for the Securities and 45 full days after the applicable Offering Date, unless sooner terminated by the Manager. The Manager may in its discretion by notice to you prior to the termination of such AAU alter any of the terms or conditions of the Offering to the extent permitted by Articles III or IV hereof, or terminate or suspend the effectiveness of Article V hereof, or any part thereof. No termination or suspension pursuant to this paragraph shall affect the Manager's authority under Section 3.1 hereof to take actions in respect of the Offering or under Article V hereof to cover any short position incurred under such AAU or in connection with covering any such short position to require you to repurchase Securities as specified in Section 5.2 hereof.

9.2. DELIVERY OR SALE OF SECURITIES; SETTLEMENT OF ACCOUNTS. Upon termination of each AAU or prior thereto at the Manager's discretion, the Manager shall deliver to you any Securities paid for by you pursuant to Section 6.1 hereof and held by the Manager for sale pursuant to Section 3.4 or 3.5 hereof but not sold and paid for and any Securities or Other Securities that are held by the Manager for your account pursuant to the provisions of Article V hereof or any Intersyndicate Agreement. Notwithstanding the foregoing, at the termination of such AAU, if the aggregate initial Offering Price of any such Securities and the aggregate purchase price of any Other Securities so held and not sold and paid for does not exceed an amount equal to 20% of the aggregate initial Offering Price of the Securities, the Manager may, in its discretion, sell such Securities and Other Securities for the accounts of the several Underwriters, at such prices, on such terms, at such times and in such manner as it may determine. Within the period specified by applicable NASD Rules or, if no period is so specified, as soon as practicable after termination of such AAU, your account shall be settled and paid. The Manager may reserve from distribution such amount as the Manager deems

12

advisable to cover possible additional expenses. The determination by the Manager of the amount so to be paid to or by you shall be final and conclusive. Any of your funds in the Manager's hands may be held with the Manager's general funds without accountability for interest.

Notwithstanding any provision of this Master AAU other than
Section 10.12, upon termination of each AAU or prior thereto at the Manager's discretion, the Manager (i) may allocate to the accounts of the Underwriters the expenses described in Section 7.2 hereof and any losses incurred upon the sale of Securities or Other Securities pursuant to the applicable AAU or any Intersyndicate Agreement (including any losses incurred upon the sale of securities referred to in Section 5.4(ii) hereof), (ii) may deliver to the Underwriters any unsold Securities or Other Securities purchased pursuant to
Section 5.1 hereof or any Intersyndicate Agreement and (iii) may deliver to the Underwriters any unsold Securities purchased pursuant to the applicable Underwriting Agreement, in each case in the Manager's discretion. The Manager shall have full discretion to allocate expenses and Securities to the accounts of any Underwriter as the Manager decides, except that (a) no Underwriter (other than the Manager or a Co-Manager) shall bear more than its share of such expenses, losses or Securities (such share shall not exceed such Underwriter's Underwriting Percentage and shall be determined pro rata among all such Underwriters based on their Underwriting Percentages), (b) no such Underwriter shall receive Securities that, together with any Securities purchased by such Underwriter pursuant to Section 6.1 (but excluding any Securities that such Underwriter is required to repurchase pursuant to Section 5.2) exceed such Underwriter's Original Purchase Obligation and (c) no Co-Manager shall bear more than its share, as among the Manager and the other Co-Managers, of such expenses, losses or Securities (such share to be determined pro rata among the Manager and all Co-Managers based on (1) their relative Underwriting Percentages as a percentage of the total combined Underwriting Percentages of the Manager and all Co-Managers, or (2) if the Manager so determines, their relative Offering Economics (as hereinafter defined) as a percentage of the combined Offering Economics of the Manager and all Co-Managers together. The Manager's or a Co-Manager's "OFFERING ECONOMICS" equals the sum of its Management Fee Share, its Underwriting Fee Share and its Selling Concession Share (each as hereinafter defined). The Manager's or a Co-Manager's "MANAGEMENT FEE SHARE" is the dollar amount of its share, as agreed among the Manager and any Co-Managers, of the amount payable by all Underwriters to some or all of the Manager and any Co-Manager as a global coordinators' fee, praecipium, management fee or other fee. The Manager's or a Co-Manager's "UNDERWRITING FEE SHARE" is the dollar amount of its Underwriting Percentage of the aggregate initial Offering Price of the Firm Securities less the Purchase Price thereof, less the Selling Concession thereon. The Manager's or a Co-Manager's "SELLING CONCESSION SHARE" is the dollar amount of any Selling Concession credited to it on sales from the institutional pot or on sales made for the account of any other Underwriter. If any Securities or Other Securities returned to you pursuant to clause (ii) or
(iii) above were not paid for by you pursuant to Section 6.1 hereof, you shall pay to the Manager an amount per security equal to the amount set forth in
Section 6.1(i), in the case of Securities returned to you pursuant to clause
(iii) above, or the purchase price of such securities, in the case of Securities or Other Securities returned to you

13

pursuant to clause (ii) above.

9.3. POST-SETTLEMENT EXPENSES. Notwithstanding any settlement on the termination of the applicable AAU, you agree to pay any transfer taxes which may be assessed and paid after such settlement on account of any sales or transfers under such AAU or any Intersyndicate Agreement for your account and your Underwriting Percentage of (i) all expenses incurred by the Manager in investigating, preparing to defend or defending against any action, claim or proceeding which is asserted or instituted by any party (including any governmental or regulatory body) relating to (a) the Registration Statement, any Preliminary Prospectus or Prospectus (or any amendment or supplement thereto), any Preliminary Offering Circular or Offering Circular (or any amendment or supplement thereto) or Supplemental Offering Materials, (b) the violation of any applicable restrictions on the offer, sale, resale or purchase of Securities or Other Securities imposed by United States Federal or state laws or foreign laws and the rules and regulations of any regulatory body promulgated thereunder or pursuant to the terms of such AAU, the Underwriting Agreement or any Intersyndicate Agreement or (c) any claim that the Underwriters constitute a partnership, an association or an unincorporated business or other separate entity and (ii) any liability, including attorneys' fees, incurred by the Manager in respect of any such action, claim or proceeding, whether such liability shall be the result of a judgment or arbitrator's determination or as a result of any settlement agreed to by the Manager, other than any such expense or liability as to which the Manager actually receives indemnity pursuant to
Section 9.4, contribution pursuant to Section 9.5, indemnity or contribution pursuant to the Underwriting Agreement or damages from an Underwriter for breach of its representations, warranties, agreements, or covenants contained in the applicable AAU. None of the foregoing provisions of this Section 9.3 shall relieve any defaulting or breaching Underwriter from liability for its defaults or breach.

9.4. INDEMNIFICATION. You agree to indemnify and hold harmless each other Underwriter and each person, if any, who controls any such Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, to the extent and upon the terms which you agree to indemnify and hold harmless any of the Issuer, the Guarantor, the Seller, any person controlling the Issuer, the Guarantor, the Seller, its directors and, in the case of a Registered Offering, its officers who signed the Registration Statement and, in the case of an Offering other than a Registered Offering, its officers, in each case as set forth in the Underwriting Agreement. You further agree to indemnify and hold harmless any investment banking firm identified in a Wire as the qualified independent underwriter as defined in Rule 2720 of the NASD's Conduct Rules ("QIU") for an Offering and each person, if any, who controls such QIU within the meaning of either Section 15 of the 1933 Act or
Section 20 of the 1934 Act, from and against any and all losses, claims, damages and liabilities related to, arising out of or in connection with such investment banking firm's activities as QIU for the Offering. You agree with the other Underwriters to reimburse such QIU for all expenses, including fees and expenses of counsel as they are incurred, in connection with investigating, preparing for, or defending any action, claim or proceeding related to, arising out of, or in connection with such QIU's activities as a QIU for the Offering. Each Underwriter shall be responsible for its Underwriting Percentage of any amount due to such QIU on

14

account of the foregoing indemnity. You agree that such QIU shall have no additional liability to any Underwriter or otherwise as a result of its serving as QIU in connection with the Offering. You further agree that to the extent the indemnification provided to a QIU under this Section 9.4 is unavailable to such QIU or insufficient in respect of any losses, claims, damages or liabilities (and expenses relating thereto), whether as a matter of law or public policy or as a result of the default of any Underwriter in performing its obligations under this Section 9.4, you and each other Underwriter shall contribute to the amount paid or payable by such QIU as a result of such losses, claims, damages or liabilities (and expenses relating thereto) in proportion to your Underwriting Percentage.

9.5. CONTRIBUTION. Notwithstanding any settlement on the termination of the applicable AAU, you agree to pay upon request of the Manager, as contribution, your Underwriting Percentage of any losses, claims, damages or liabilities, joint or several, paid or incurred by any Underwriter to any person other than an Underwriter, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus or Prospectus (or any amendment or supplement thereto), any Preliminary Offering Circular or Offering Circular (or any amendment or supplement thereto) or Supplemental Offering Materials or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (other than an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information furnished to the Company in writing by the Underwriter on whose behalf the request for contribution is being made expressly for use therein) and your Underwriting Percentage of any legal or other expenses reasonably incurred by the Underwriter (with the approval of the Manager) on whose behalf the request for contribution is being made in connection with investigating or defending any such loss, claim, damage or liability or any action in respect thereof; provided that no request shall be made on behalf of any Underwriter guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) from any Underwriter who was not guilty of such fraudulent misrepresentation. None of the foregoing provisions of this Section 9.5 shall relieve any defaulting or breaching Underwriter from liability for its defaults or breach.

9.6. SEPARATE COUNSEL. If any claim is asserted or action or proceeding commenced pursuant to which the indemnity provided in Section 9.4 may apply, the Manager may take such action in connection therewith as it deems necessary or desirable, including retention of counsel for the Underwriters, and in its discretion separate counsel for any particular Underwriter or group of Underwriters, and the fees and disbursements of any counsel so retained shall be allocated among the several Underwriters as determined by the Manager. Any Underwriter may elect to retain at its own expense its own counsel and, on advice of such counsel but only with the consent of the Manager, may settle or consent to the settlement of any such claim, action or proceeding. The Manager may settle or consent to the settlement of any such claim, action or proceeding. Whenever the Manager receives notice of the assertion of any claim, action or proceeding to which the provisions of Section 9.4 would apply, it will give prompt notice thereof to each Underwriter, and whenever you receive notice of the

15

assertion of any claim or commencement of any action or proceeding to which the provisions of Section 9.4 would apply, you will give prompt notice thereof to the Manager. The Manager also will furnish each Underwriter with periodic reports, at such times as it deems appropriate, as to the status of such claim, action or proceeding, and the action taken by it in connection therewith.

9.7. SURVIVAL OF AGREEMENTS. Regardless of any termination of an AAU, your agreements contained in Article V and Sections 3.1, 9.3, 9.4, 9.5, 9.6 and 11.2 shall remain operative and in full force and effect regardless of
(i) any termination of the Underwriting Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Issuer, the Guarantor, the Seller, its directors or officers or any person controlling the Issuer, the Guarantor or the Seller and
(iii) acceptance of any payment for any Securities.

10.10. OFFERING RESTRICTIONS. If you are a foreign bank or dealer and you are not registered as a broker-dealer under Section 15 of the 1934 Act, you agree that while you are acting as an Underwriter in respect of the Securities and in any event during the term of the applicable AAU, you will not directly or indirectly effect in, or with persons who are nationals or residents of, the United States, its territories or possessions any transactions (except for the purchases provided for in the Underwriting Agreement and transactions contemplated by Articles III and V hereof) in Securities or any Other Securities.

It is understood that, except as specified in the applicable AAU, no action has been taken by the Manager, the Issuer, the Guarantor or the Seller to permit you to offer Securities in any jurisdiction other than the United States, in the case of a Registered Offering, where action would be required for such purpose.

If any Underwriter so advises the Manager, the Manager may allocate any such purchases, sales and over-allotments (and the related expenses) which otherwise would have been allocated to your account based on your respective Underwriting Percentage to your account based on the ratio of your Original Purchase Obligation to the Original Purchase Obligations of all Underwriters other than the advising Underwriter or Underwriters or in such other manner as the Manager shall determine.

If the Underwriting Agreement is terminated as permitted by the terms thereof, your obligations hereunder with respect to the Offering of the Securities shall immediately terminate except (i) as set forth in Section 9.7, (ii) that you shall remain liable for your Underwriting Percentage (or such other percentage as may be specified pursuant to Section 9.2) of all expenses and for any purchases or sales which may have been made for your account pursuant to the provisions of Article V hereof or any Intersyndicate Agreement and (iii) that such termination shall not affect any obligations of any defaulting or breaching Underwriter.

Section 9.2, 9.3, 9.4, 9.5, 9.6 or 11.1, you will assume your proportionate share (determined on the basis of the respective Underwriting Percentages of the non-defaulting Underwriters) of such obligations, but no such assumption shall relieve any defaulting Underwriter from liability to the non-defaulting Underwriters, the Issuer, the Guarantor or the Seller for its default.

11.3. ARRANGEMENTS FOR PURCHASES. The Manager is authorized to arrange for the purchase by others (including the Manager or any other Underwriter) of any Securities not purchased by any defaulting Underwriter in accordance with the terms of the applicable Underwriting Agreement or, if the applicable Underwriting Agreement does not provide arrangements for defaulting Underwriters, in the discretion of the Manager. If such arrangements are made, the respective amounts of Securities to be purchased by the remaining Underwriters and such other person or persons, if any, shall be taken as the basis for all rights and obligations hereunder, but this shall not relieve any defaulting Underwriter from liability for its default.

XII. MISCELLANEOUS

12.1. OBLIGATIONS SEVERAL. Nothing contained in this Salomon Smith Barney Master AAU or any AAU constitutes you partners with the Manager or with the other Underwriters and the obligations of you and each of the other Underwriters are several and not joint.

EXHIBIT A
JUNE 1, 1999

SALOMON SMITH BARNEY INC.
UNDERWRITERS' QUESTIONNAIRE

In connection with each Offering covered by the Salomon Smith Barney Inc. Master Agreement Among Underwriters dated June 1, 1999, we confirm that except as set forth in a timely reply by us to the Invitation Wire:

(1) Neither we nor any of our directors, officers or partners have a material relationship (as "material" is defined in Regulation C under the 1933 Act) with the Issuer, the Guarantor or any Seller.

(2) (If the offer and sale of the Securities are to be registered under the 1933 Act pursuant to a Registration Statement on Form S-1 of Form F-1:) Neither we nor any "group" (as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) of which we are a member is the beneficial owner (determined in accordance with Rule 13d-3 under the Exchange Act) of more than 5% of any class of voting securities of the Issuer or the Guarantor, nor do we have any knowledge that more than 5% of any class of voting securities of the Issuer or the Guarantor is held or to be held subject to any voting trust or other similar agreement.

(3) Other than as may be stated in the Salomon Smith Barney Master Agreement Among Underwriters dated June 1, 1999, the applicable AAU, the Intersyndicate Agreement or dealer agreement, if any, the Prospectus, the Registration Statement or the Offering Circular, we do not know and have no reason to believe that there is an intention to over-allot or that the price of any security may be stabilized to facilitate the offering of the Securities.

(4) Except as described in the Prospectus or Offering Circular, as the case may, be and the Invitation Wire, we do not know of any discounts or commissions to be allowed or paid to dealers, including all cash, securities, contracts or other consideration to be received by any dealer in connection with the sale of the securities.

22

(5) We have not prepared any report or memorandum for external use in connection with the Offering. (If there are any exceptions, (i) furnish four (4) copies of each report and memorandum to Salomon Smith Barney Inc., 388 Greenwich Street, New York, N.Y. 10013, Attention:
Investment Banking Department/Transaction Structuring Group, (ii) identify each class of person who received such material and the number of copies distributed to each such class, and (iii) indicate when such distribution commenced and ceased.)

(6) (If the offer and sale of the Securities are to be registered under the 1933 Act pursuant to a Registration Statement on Form S-1 or Form F-1:) We have not within the past twelve months prepared or had prepared for us any engineering, management or similar report or memorandum relating to broad aspects of the business, operations or products of the Issuer or the Guarantor. (The immediately preceding sentence does not apply to reports solely comprised of recommendations to buy, sell or hold the Issuer's or the Guarantor's securities, unless such recommendations have changed within the past six months or to information already contained in documents filed with the Commission. If there are any exceptions, (i) furnish four (4) copies of each report and memorandum to Salomon Smith Barney Inc. 388 Greenwich Street, New York, N.Y. 10013, Attention: Investment Banking Department/Transaction Structuring Group, (ii) identify each class of persons who received such material and the number of copies distributed to each such class, and (iii) indicate when such distribution commenced and ceased.)

(7) We are not an "affiliate" of the Issuer or the Guarantor for purposes of Rule 2720 of the National Association of Securities Dealers, Inc.'s ("NASD") Conduct Rules. We understand that under Rule 2720 (except as provided in Rule 2720(b)(1)(C) thereof) two entities are "affiliates" of each other if one entity controls, is controlled by, or is under common control with, the second entity and that "control" is presumed to exist if one entity (or, in the case of an NASD member, the entity and all "persons associated with" it (as defined in the NASD By-Laws)) beneficially owns 10% or more of the second entity's outstanding voting securities or, if the second entity is a partnership, if the first entity has a partnership interest in 10% or more of the second entity's distributable profits or losses.

In that regard, we specifically confirm that we, our "parent" (as defined in Rule 2720), affiliates and "persons associated with" us (as defined in the NASD By-Laws), in the aggregate do not (i) beneficially own 10% or more of the Issuer's or the Guarantor's "common equity", "preferred equity", or "subordinated debt" (as each such term is defined in Rule 2720), or (ii) in the case of an Issuer or Guarantor which is a partnership,

beneficially own a general, limited or special partnership interest in 10% or more of the Issuer's or Guarantor's distributable profits or losses.

(10) (If filing with the NASD is required:) There is no association or affiliation between us and (i) any officer or director of the Issuer, the Guarantor or any Issuer Related Party, or (ii) any securityholder of five percent or more (or, in the case of an initial public offering of equity securities, any securityholder) of any class of securities of the Issuer, the Guarantor or an Issuer Related Party; it being understood that for purposes of paragraph (9) above and this paragraph (10), the term "Issuer Related Party" includes any Seller, any affiliate of the Issuer the Guarantor or a Seller and the officers or general partners, directors, employees and securityholders thereof.

24

parent, if any. Neither the Trustee nor its parent, if any, nor any of their directors or executive officers is a "director, officer, partner, employee, appointee or representative" of ours (as those terms are defined in the Trust Indenture Act of 1939 or in the relevant instructions to Form T-1). We and our directors, partners, and executive officers, taken as a group, did not on the date specified in the Invitation Wire, and do not, own beneficially 1% or more of the shares of any class of voting securities of the Trustee or of its parent, if any. If we are a corporation, we do not have outstanding and have not assumed or guaranteed any securities issued otherwise than in our present corporate name.

(13) (If the Issuer is a public utility:) We are not a "holding company" or a "subsidiary company" or an "affiliate" of a "holding company" or of a "public-utility company", each as defined in the Public Utility Holding Company Act of 1935.

(14) If we are, or we are affiliated with, a U.S. or non-U.S. bank, we hereby represent that our participation in the offering of the Securities on the terms contemplated in the applicable AAU and the proposed Underwriting Agreement does not contravene any U.S. or state banking law restricting the exercise of securities powers in the United States.

Capitalized terms used but not defined herein shall have the respective meanings given to them in the applicable AAU.

2.2 Preparation for Each Auction; Maintenance of Registry of Beneficial Owners.

(a) Not later than seven days prior to the first Auction Date for the first series of MuniPreferred subject to an Auction, the Fund shall provide the Auction Agent with a list of

3

the Broker-Dealers. Not later than seven days prior to any Auction Date for any series of MuniPreferred for which any change in such list of Broker-Dealers is to be effective, the Fund will notify the Auction Agent in writing of such change and, if any such change involves the addition of a Broker-Dealer to such list, shall cause to be delivered to the Auction Agent for execution by the Auction Agent a Broker-Dealer Agreement signed by such Broker-Dealer; provided, however, that if the Fund proposes to designate any Special Rate Period of any series of MuniPreferred pursuant to Section 4 of Part I of the Statement, not later than 11:00 A.M. on the Business Day next preceding the Auction next preceding the first day of such Rate Period or by such later time or date, or both, as may be agreed to by the Auction Agent, the Fund shall provide the Auction Agent with a list of the Broker-Dealers for such series and a manually signed copy of each Broker-Dealer Agreement or a new Schedule A to a Broker-Dealer Agreement (which Schedule A shall replace and supersede any previous Schedule A to such Broker-Dealer Agreement) with each Broker-Dealer for such series. The Auction Agent and the Fund shall have entered into a Broker-Dealer Agreement with each Broker-Dealer prior to the participation of any such Broker-Dealer in any Auction.

(b) In the event that any Auction Date for any series of MuniPreferred shall be changed after the Auction Agent shall have given the notice referred to in clause (vi) of paragraph (a) of the Settlement Procedures, or after the notice referred to in Section 2.5(a) hereof, if applicable, the Auction Agent, by such means as the Auction Agent deems practicable, shall give notice of such change to the Broker-Dealers for such series not later than the earlier of 9:15 A.M. on the new Auction Date or 9:15 A.M. on the old Auction Date.

(c) (i) The Auction Agent shall maintain a registry of the beneficial owners of the shares of MuniPreferred of each series who shall constitute Existing Holders of shares of MuniPreferred of such series for purposes of Auctions and shall indicate thereon the identity of the respective Broker-Dealer of each Existing Holder, if any, on whose behalf such Broker-Dealer submitted the most recent Order in any Auction which resulted in such Existing Holder continuing to hold or purchasing shares of MuniPreferred of such series. The Auction Agent shall keep such registry current and accurate. The Fund shall provide or cause to be provided to the Auction Agent at or prior to the Date of Original Issue of the shares of MuniPreferred of each series a list of the initial Existing Holders of the shares of each such series of MuniPreferred, the number of shares purchased by each such Existing Holder and the respective Broker-Dealer of each such Existing Holder or the affiliate thereof through which each such Existing Holder purchased such shares. The Auction Agent shall advise the Fund in writing whenever the number of Existing Holders is 500 or more. The Auction Agent may rely upon, as conclusive evidence of the identities of the Existing Holders of shares of MuniPreferred of any series (A) such list, (B) the results of Auctions, (C) notices from any Broker-Dealer as described in the first sentence of Section 2.2(c)(iii) hereof and (D) the results of any procedures approved by the Fund that have been devised for the purpose of determining the identities of Existing Holders in situations where shares of MuniPreferred may have been transferred without compliance with any restriction on the transfer thereof set forth in the Auction Procedures.

4

(ii) In the event of any partial redemption of any series of MuniPreferred, the Auction Agent shall, at least two Business Days prior to the next Auction for such series, request each Broker-Dealer to provide the Auction Agent with a list of Persons who such Broker-Dealer believes should remain Existing Holders after such redemption based upon inquiries of those Persons such Broker-Dealer believes are Beneficial Owners as a result of the most recent Auction and with respect to each such Person, the number of shares of MuniPreferred of such series such Broker-Dealer believes are owned by such Person after such redemption. In the absence of receiving any such information from any Broker-Dealer, the Auction Agent may continue to treat the Persons listed in its registry of Existing Holders as the beneficial owner of the number of shares of MuniPreferred of such series shown in such registry.

(iii) The Auction Agent shall be required to register a transfer of shares of MuniPreferred of any series from an Existing Holder of such shares of MuniPreferred only if such transfer is to another Existing Holder, or other Person if permitted by the Fund, and only if such transfer is made (A) pursuant to an Auction, (B) the Auction Agent has been notified in writing (I) in a notice substantially in the form of Exhibit C to the Broker-Dealer Agreements by a Broker-Dealer of such transfer or (II) in a notice substantially in the form of Exhibit D to the Broker-Dealer Agreements by the Broker-Dealer of any Existing Holder, or other Person if permitted by the Fund, that purchased or sold such shares of MuniPreferred in an Auction of the failure of such shares of MuniPreferred to be transferred as a result of such Auction or
(C) pursuant to procedures approved by the Fund that have been devised for the purpose of determining the identities of Existing Holders in situations where shares of MuniPreferred may have been transferred without compliance with any restriction on the transfer thereof set forth in the Auction Procedures. The Auction Agent is not required to accept any such notice for an Auction unless it is received by the Auction Agent by 3:00 P.M. on the Business Day preceding such Auction.

(d) The Auction Agent may request the Broker-Dealers, as set forth in the Broker-Dealer Agreements, to provide the Auction Agent with a list of Persons who such Broker-Dealer believes should be Existing Holders based upon inquiries of those Persons such Broker-Dealer believes are Beneficial Owners as a result of the most recent Auction and with respect to each such Person, the number of shares of such series of MuniPreferred such Broker-Dealer believes to be owned by such Person. The Auction Agent shall keep confidential such registry of Existing Holders and shall not disclose the identities of the Existing Holders of such shares of MuniPreferred to any Person other than the Fund and the Broker-Dealer that provided such information.

2.3 Information Concerning Rates.

(a) The Rate Multiple on the date of the Agreement is set forth in the Request and Acceptance Letter. If there is any change in the credit rating of MuniPreferred by either of the rating agencies (or substitute or successor rating agencies) referred to in the definition of "Rate Multiple" resulting in any change in the Rate Multiple for MuniPreferred after the date of the

5

Request and Acceptance Letter, the Fund shall notify the Auction Agent in writing of such change in the Rate Multiple prior to 12:00 Noon on the Business Day prior to the next Auction Date for any series of MuniPreferred succeeding such change. If the Fund designates all or a portion of any dividend on shares of any series of MuniPreferred to consist of net capital gains or other income taxable for Federal income tax purposes, it will indicate, in its notice in the form of Exhibit I hereto to the Auction Agent pursuant to Section 2.6 hereof, the Rate Multiple for such series to be in effect for the Auction Date on which the dividend rate for such dividend is to be fixed. In determining the Maximum Rate for any series of MuniPreferred on any Auction Date as set forth in Section 2.3(b)(i) hereof, the Auction Agent shall be entitled to rely on the last Rate Multiple for MuniPreferred of which it has most recently received notice from the Fund (or, in the absence of such notice, the percentage set forth in the Request and Acceptance Letter), except that if the Fund shall have notified the Auction Agent of a Rate Multiple to be in effect for an Auction Date in accordance with the preceding sentence, the Rate Multiple in effect for the next succeeding Auction Date of any series of MuniPreferred shall be, unless the Fund notifies the Auction Agent of a change in the Rate Multiple for such succeeding Auction Date pursuant to this Section 2.3(a), the Rate Multiple that was in effect on the first preceding Auction Date for MuniPreferred with respect to which the dividend, the rate for which was fixed on such Auction Date, did not include any net capital gains or other income taxable for Federal income tax purposes.

(b) (i) On each Auction Date for any series of MuniPreferred, the Auction Agent shall determine the Maximum Rate for such series. The Maximum Rate for any series of MuniPreferred on any Auction Date shall be:

(A) in the case of any Auction Date which is not the Auction Date immediately prior to the first day of any proposed Special Rate Period designated by the Fund pursuant to Section 4 of Part I of the Statement, the product of (1) the Reference Rate on such Auction Date for the next Rate Period of such series and (2) the Rate Multiple on such Auction Date, unless such series has or had a Special Rate Period (other than a Special Rate Period of 28 Rate Period Days or fewer) and an Auction at which Sufficient Clearing Bids existed has not yet occurred for a Minimum Rate Period of such series after such Special Rate Period, in which case the higher of:

(1) the dividend rate on shares of such series for the then-ending Rate Period; and

(2) the product of (x) the higher of (I) the Reference Rate on such Auction Date for a Rate Period equal in length to the then-ending Rate Period of such series, if such then ending Rate Period was 364 Rate Period Days or fewer, or the Treasury Note Rate on such Auction Date for a Rate Period equal in length to the then-ending Rate Period of such series, if such then ending Rate Period was more than 364 Rate Period Days, and (II) the Reference Rate on such Auction Date for a Rate Period equal in length to such Special Rate Period of such series, if such

6

Special Rate Period was 364 Rate Period Days or fewer, or the Treasury Note Rate on such Auction Date for a Rate Period equal in length to such Special Rate Period, if such Special Rate Period was more than 364 Rate Period Days and (y) the Rate Multiple on such Auction Date; or

(B) in the case of any Auction Date which is the Auction Date immediately prior to the first day of any proposed Special Rate Period designated by the Fund pursuant to Section 4 of Part I of the Statement, the product of (1) the highest of (x) the Reference Rate on such Auction Date for a Rate-Period equal in length to the then-ending Rate Period of such series, if such then-ending Rate Period was 364 Rate Period Days or fewer, or the Treasury Note Rate on such Auction Date for a Rate Period equal in length to the then-ending Rate Period of such Rate Period, if such then-ending Rate Period was more than 364 Rate Period Days, (y) the Reference Rate on such Auction Date for the Special Rate Period for which the Auction is being held if such Special Rate Period is 364 Rate Period Days or fewer or the Treasury Note Rate on such Auction Date for the Special Rate Period for which the Auction is being held if such Special Rate Period is more than 364 Rate Period Days, and (z) the Reference Rate on such Auction Date for Minimum Rate Periods and (2) the Rate Multiple on such Auction Date.

Not later than 9:30 A.M. on each Auction Date the Auction Agent shall notify the Fund and the Broker-Dealers of the Maximum Rate so determined and the "AA" Composite Commercial Paper Rate(s), the Taxable Equivalent of the Short-Term Municipal Bond Rate(s), Treasury Note Rate(s) and Treasury Bill Rate(s), as the case may be, used to make such determination.

(ii) From and after a Failure to Deposit by the Fund during any Rate Period of any series of MuniPreferred, until such failure is cured and a Late Charge (as defined in paragraph (a) of Section 2.7), is paid, in accordance with subparagraph (e)(i) of Section 2 of Part I of the Statement, on the first day of each Rate Period of such series the Auction Agent shall determine the Treasury Note Rate for such Rate Period of more than 364 Rate Period Days and the Reference Rate for Rate Periods of 364 Rate Period Days or fewer. Not later than 9:30 A.M. on each such first day, the Auction Agent shall notify the Fund of the applicable Reference Rate and Treasury Note Rate.

(iii) If any "AA" Composite Commercial Paper Rate, Taxable Equivalent of the Short-Term Municipal Bond Rate, Treasury Note Rate or Treasury Bill Rate, as the case may be, is not quoted on an interest or bond equivalent, as the case may be, basis, the Auction Agent shall convert the quoted rate to the interest or bond equivalent thereof as set forth in the definition of such rate in the Statement if the rate obtained by the Auction Agent is quoted on a discount basis, or if such rate is quoted on a basis other than an interest or bond equivalent or discount basis the Auction Agent shall convert the quoted rate to an interest or bond equivalent rate after consultation with the Fund as to the method of such conversion.

7

(iv) If any "AA" Composite Commercial Paper Rate is to be based on rates supplied by Commercial Paper Dealers and one or more of the Commercial Paper Dealers shall not provide a quotation for the determination of such "AA" Composite Commercial Paper Rate, the Auction Agent shall immediately notify the Fund so that the Fund can determine whether to select a Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers to provide the quotation or quotations not being supplied by any Commercial Paper Dealer or Commercial Paper Dealers. The Fund shall promptly advise the Auction Agent of any such selection.

(v) If any Treasury Note Rate or Treasury Bill Rate is to be based on rates supplied by U.S. Government Securities Dealers and one or more of the U.S. Government Securities Dealers shall not provide a quotation for the determination of such Treasury Rate, the Auction Agent shall immediately notify the Fund so that the Fund can determine whether to select a Substitute U.S. Government Securities Dealer or Substitute U.S. Government Securities Dealers to provide the quotation or quotations not being supplied by any U.S. Government Securities Dealer or U.S. Government Securities Dealers. The Fund shall promptly advise the Auction Agent of any such selection.

(c) The maximum marginal tax rate referred to in the definition of "Rate Multiple" in the Statement is referred to in this Agreement as the "Highest Marginal Rate." The Highest Marginal Rate on the date of the Agreement is set forth in the Request and Acceptance Letter. If there is any change in the Highest Marginal Rate, the Fund shall notify the Auction Agent in writing of such change prior to 12:00 Noon on the Business Day prior to the next Auction Date for MuniPreferred succeeding such change. In determining the Maximum Rate for any series of MuniPreferred on any Auction Date, the Auction Agent shall be entitled to rely on the Highest Marginal Rate of which it has most recently received notice from the Fund (or, in the absence of such notice, the percentage set forth in the Request and Acceptance Letter).

2.4 Auction Schedule.

The Auction Agent shall conduct Auctions in accordance with the schedule set forth below. Such schedule may be changed by the Auction Agent with the consent of the Fund, which consent shall not be unreasonably withheld. The Auction Agent shall give written notice of any such change to each Broker-Dealer. Such notice shall be given prior to the close of business on the Business Day next preceding the first Auction Date on which any such change shall be effective.

then the Auction Agent shall deliver a notice in the form of Exhibit H hereto to the Broker-Dealers for such series not later than one Business Day after the receipt of the payment from the Fund curing such Failure to Deposit and such Late Charge.

(c) A Failure to Deposit with respect to shares of MuniPreferred shall have been cured (if such Failure to Deposit is not solely due to the willful failure to the Fund to make the required payment to the Auction Agent) with respect to any Rate Period if, within the respective time periods described immediately above, the Fund shall have paid to the Auction Agent (i) all accumulated and unpaid dividends on the shares of MuniPreferred and (ii) without duplication, the Redemption Price for the shares of MuniPreferred, if any, for which Notice of Redemption has been mailed; provided, however, that the foregoing clause (ii) shall not apply to the Fund's failure to pay the Redemption Price in respect of shares of MuniPreferred when the related Redemption Notice provides that redemption of such shares is subject to one or more conditions precedent and each such condition precedent shall not have been satisfied at the time or times and in the manner specified in such Notice of Redemption.

The Auction Agent may issue new certificates in exchange for and upon the cancellation of mutilated certificates.

Rate is to be determined by an Auction. Each periodic operation of such procedures is hereinafter referred to as an "Auction."

BD understands that other Persons meeting the requirements specified in the definition of "Broker-Dealer" contained in the Auction Procedures may execute Agreements and participate as Broker-Dealers in Auctions.

2.2. Preparation for Each Auction.

(a) Not later than 9:30 A.M. on each Auction Date for any series of MuniPreferred, the Auction Agent for such series shall advise the Broker-Dealers for such series by telephone of the Maximum Rate therefor and the Reference Rate(s) and Treasury Note Rate(s), as the case may be, used in determining such Maximum Rate.

(b) In the event that any Auction Date for any series of MuniPreferred shall be changed after the Auction Agent for such series has given the notice referred to in clause (vi) of paragraph (a) of the Settlement Procedures, or after the notice referred to in Section 2.5(a) hereof, if applicable, such Auction Agent, by such means as such Auction Agent deems practicable, shall give notice of such change to BD, if it is a Broker-Dealer for such series, not later than the earlier of 9:15 A.M. on the new Auction Date or 9:15 A.M. on the old Auction Date.

BD shall comply with any such request relating to a series of MuniPreferred in respect of which BD was named a Broker-Dealer, and the Auction Agent shall keep confidential any such information so provided by BD and shall not disclose any information so provided by BD to any Person other than the Fund and BD.

(d) BD agrees to maintain a list of customers relating to a series of MuniPreferred and to use its best efforts, subject to existing laws and regulations, to contact the customers on such list whom BD believes may be interested in participating in the Auction on each Auction Date, as a Potential Holder or a Potential Beneficial Owner, for the purposes set forth in

2.3. Auction Schedule; Method of Submission of Orders.

Such notice shall be given prior to the close of business on the Business Day next preceding the first Auction Date on which such change shall be effective.

BD shall submit a separate Order to such Auction Agent for each Potential Holder or Existing Holder with respect to whom BD is submitting an Order and shall not otherwise net or aggregate such Orders prior to their submission to such Auction Agent.

Such Auction Agent is not required to accept any such notice described in clause (i) for an Auction unless it is received by the Auction Agent by 3:00 P.M. on the Business Day preceding such Auction.

(d) BD and other Broker-Dealers may submit Orders in Auctions for their own accounts (including Orders for their own accounts where the Order is placed beneficially for a customer) unless the relevant Fund shall have notified BD and all other Broker-Dealers that they may no longer do so, in which case Broker-Dealers may continue to submit Hold Orders and Sell Orders for their own accounts.

(e) BD agrees to handle its customers' orders in accordance with its duties under applicable securities laws and rules.

(f) To the extent that pursuant to Section 4 of the Auction Procedures of any Fund, BD continues to hold, sells, or purchases a number of shares that is fewer than the number of shares in an Order submitted by BD to the Auction Agent in which BD designated itself as an

6

Existing Holder or Potential Holder in respect of customer Orders, BD shall make appropriate pro rata allocations among its customers for which it submitted Orders of similar tenor. If as a result of such allocations, any Beneficial Owner would be entitled or required to sell, or any Potential Beneficial Owner would be entitled or required to purchase, a fraction of a share of MuniPreferred on any Auction Date, BD shall, in such manner as it shall determine in its sole discretion, round up or down the number of shares of MuniPreferred to be purchased or sold on such Auction Date by any Beneficial Owner or Potential Beneficial Owner on whose behalf BD submitted an Order so that the number of shares so purchased or sold by each such Beneficial Owner or Potential Beneficial Owner on such Auction Date shall be whole shares of MuniPreferred.

2.4. Notices.

(a) If any Fund delivers to its Auction Agent a notice of the Auction Date for any series of MuniPreferred of such Fund for a Rate Period thereof that next succeeds a Rate Period that is not a Minimum Rate Period in the form of Exhibit C to the Auction Agency Agreement, and BD is a Broker-Dealer of such series, the Auction Agent shall deliver such notice to BD as promptly as practicable after its receipt of such notice from such Fund.

(b) If the Board of Directors or Board of Trustees, as the case may be, of any Fund proposes to designate any succeeding Subsequent Rate Period of any series of MuniPreferred of such Fund as a Special Rate Period and such Fund delivers to its Auction Agent a notice of such proposed Special Rate Period in the form of Exhibit D to the Auction Agency Agreement, and BD is a Broker-Dealer for such series, such Auction Agent shall deliver such notice to BD as promptly as practicable after its receipt of such notice from the Fund.

(c) If the Board of Directors or Board of Trustees, as the case may be, of any Fund determines to designate such succeeding Subsequent Rate Period as a Special Rate Period, and such Fund delivers to its Auction Agent a notice of such Special Rate Period in the form of Exhibit E to the Auction Agency Agreement not later than 11:00 A.M. on the second Business Day next preceding the first day of such Rate Period (or by such later time or date, or both, as

7

may be agreed to by such Auction Agent), and BD is a Broker-Dealer for such series, such Auction Agent shall deliver such notice to BD not later than 3:00 P.M. on such second Business Day (or, if such Auction Agent has agreed to a later time or date, as promptly as practicable thereafter).

2.6. Allocation of Taxable Income.

If any Fund delivers to its Auction Agent a notice in the form of Exhibit I to the Auction Agency Agreement designating all or a portion of any dividend on shares of any series of MuniPreferred of such Fund to consist of net capital gains or other income taxable for Federal income tax purposes, and BD is a Broker-Dealer for such series, such Auction Agent shall deliver such notice to BD on the Business Day following its receipt of such notice from such Fund. On or prior to the Auction Date referred to in such notice, BD will contact each of its customers that is a Beneficial Owner of shares of such series of MuniPreferred or a Potential Beneficial Owner of shares of such series of MuniPreferred interested in submitting an Order in the Auction to be held on such Auction Date, and BD will notify such Beneficial Owners and Potential Beneficial Owners of the contents of such notice. BD will be deemed to have notified such Beneficial Owners and Potential Beneficial Owners if, for each of them, (i) BD makes a reasonable effort to contact such Beneficial Owner or Potential Beneficial Owner by telephone, and (ii) upon failing to contact such Beneficial Owner or Potential Beneficial Owner by telephone BD mails written notification to such Beneficial Owner or Potential Beneficial Owner at the mailing address indicated in the account records of BD.

then, if BD is a Broker-Dealer for such series, such Auction Agent shall deliver a notice in the form of Exhibit G to the Auction Agency Agreement by first-class mail, postage prepaid, to BD not later than one Business Day after its receipt of the payment from such Fund curing such Failure to Deposit and such Late Charge.

2.8. Service Charge to be Paid to BD.

On the Business Day next succeeding each Auction Date for any series of MuniPreferred specified in, or on Schedule A to, the Request Letter of any Fund, the Auction Agent for such series shall pay to BD from moneys received from such Fund an amount equal to the product of (a) (i) in the case of any Auction Date immediately preceding a Rate Period of such series consisting of 364 Rate Period Days or fewer, 1/4 of 1%, or (ii) in the case of any Auction Date immediately preceding a Rate Period of such series consisting of more than 364 Rate Period Days, such percentage as may be agreed upon by such Fund and BD with respect to such Rate Period, times (b) a fraction, the numerator of which is the number of Rate Period Days in the Rate Period therefor beginning on such Business Day and the denominator of which is 365 if such Rate Period consists of 7 Rate Period Days and 360 for all other Rate Periods, times (c) $50,000 times
(d) the sum of (i) the aggregate number of shares of such series placed by BD in such Auction that were (A) the subject of Submitted Bids of Existing Holders submitted by BD and continued to be held as a result of such submission and (B) the subject of Submitted Bids of Potential Holders submitted by BD and purchased as a result of such submission plus (ii) the aggregate number of shares of such series subject to valid Hold Orders (determined in accordance with paragraph (d) of Section 2 of the Auction Procedures) submitted to the Auction Agent by BD plus (iii) the number of shares of MuniPreferred deemed to be subject to Hold Orders of Existing Holders pursuant to paragraph (c) of Section 2 of the Auction Procedures of such Fund that were acquired by BD for its own account or were acquired by BD for its customers who are Beneficial Owners.

For purposes of subclause (d)(iii) of the foregoing paragraph, if any Existing Holder or Beneficial Owner who acquired shares of any series of MuniPreferred through BD transfers those shares to another Person other than pursuant to an Auction, then the Broker-Dealer for the shares so transferred shall continue to be BD; provided, however, that if the transfer was effected by, or if the transferee is, a Broker-Dealer other than BD, then such Broker-Dealer shall be the Broker-Dealer for such shares.

2.9. Settlement.

(a) If any Existing Holder or Beneficial Owner with respect to whom BD has submitted a Bid or Sell Order for shares of MuniPreferred of any series that was accepted in whole or in part fails to instruct its Agent Member to deliver the shares of MuniPreferred subject to such Bid or Sell Order against payment therefor, BD, if it knows the identity of such Agent Member, shall instruct such Agent Member to deliver such shares against payment therefor and, if such Agent Member fails to comply with such instructions, BD may deliver to the Potential Holder or Potential Beneficial Owner with respect to whom BD submitted a Bid for shares of MuniPreferred of such series that was accepted in whole or in part a number of shares of MuniPreferred of such

10

series that is less than the number of shares of MuniPreferred of such series specified in such Bid to be purchased by such Potential Holder or Potential Beneficial Owner.

(b) Neither the Auction Agent nor the Fund shall have any responsibility or liability with respect to the failure of an Existing Holder, Beneficial Owner, Potential Holder or Potential Beneficial Owner or its respective Agent Member to deliver shares of MuniPreferred of any series or to pay for shares of MuniPreferred of any series sold or purchased pursuant to the Auction Procedures or otherwise.

(c) Notwithstanding any provision of the Auction Procedures or the Settlement Procedures to the contrary, in the event BD is an Existing Holder with respect to shares of a series of MuniPreferred and the Auction Procedures provide that BD shall be deemed to have submitted a Sell Order in an Auction with respect to such shares if BD fails to submit an Order in that Auction with respect to such shares, BD shall have no liability to any Person for failing to sell such shares pursuant to such a deemed Sell Order if (i) such shares were transferred by the beneficial owner thereof without notification of such transfer in compliance with the Auction Procedures or (ii) BD has indicated to the Auction Agent pursuant to Section 2.2(e) of this Agreement that, according BD's records, BD is not the Existing Holder of such shares.

(d) Notwithstanding any provision of the Auction Procedures or the Settlement Procedures to the contrary, in the event an Existing Holder or Beneficial Owner of shares of a series of MuniPreferred with respect to whom a Broker-Dealer submitted a Bid to the Auction Agent for such shares that was accepted in whole or in part, or submitted or is deemed to have submitted a Sell Order for such shares that was accepted in whole or in part, fails to instruct its Agent Member to deliver such shares against payment therefor, partial deliveries of shares of MuniPreferred that have been made in respect of Potential Holders' or Potential Beneficial Owners' Submitted Bids for shares of such series that have been accepted in whole or in part shall constitute good delivery to such Potential Holders and Potential Beneficial Owners.

(e) Notwithstanding the foregoing terms of this Section, any delivery or non-delivery of shares of MuniPreferred of any series which represents any departure from the results of an Auction for shares of such series, as determined by the Auction Agent, shall be of no effect for purposes of the registry of Existing Holders maintained by the Auction Agent pursuant to the Auction Agency Agreement unless and until the Auction Agent shall have been notified of such delivery or non-delivery.

(f) The Auction Agent shall have no duty or liability with respect to enforcement of this Section 2.9.

Reference is made to (a) the Broker-Dealer Agreements executed by the Funds (as hereinafter defined) listed on Exhibit A hereto, Bankers Trust Company and various broker-dealers, copies of which will be made available to you upon request by Bankers Trust Company (the "Broker-Dealer Agreements") and
(b) the Nuveen Broker-Dealer Agreement-Basic Terms for Acting as a Broker-Dealer dated December 14, 1993, receipt of which is hereby acknowledged by you (the "Basic Terms"). For purposes of this letter ("Acceptance Letter"), (a) "Fund" shall mean any closed-end investment company registered under the Investment Company Act of 1940, as amended, for which Nuveen Advisory Corp. acts as investment adviser; (b) except as otherwise provided below, the terms of each Broker-Dealer Agreement shall be incorporated herein by reference, and you shall be considered BD for all purposes thereof, as if you were the Broker-Dealer signatory thereto in the place of the actual Broker-Dealer signatory thereto; and (c) the Basic Terms are incorporated herein by reference, you shall be considered BD for all purposes thereof, Bankers Trust Company shall be considered the Auction Agent for all purposes thereof, and each Fund not listed on Exhibit A hereto shall be considered a Fund for all purposes thereof.

We hereby request that you act as a Broker-Dealer for the Money Market Cumulative Preferred Stock ("MMP") of each series, and the Municipal Auction Rate Cumulative Preferred Stock or Shares ("MPS" or "MuniPreferred") of each series, of each Fund that executes a letter, substantially in the form attached hereto as Exhibit B or Exhibit C, as appropriate, appointing you as a Broker-Dealer ("Request Letter"). You hereby
(a) accept such appointment as a Broker-Dealer for each series of MMP, MPS or MuniPreferred of each Fund identified in a Request Letter and (b) agree to act as BD in accordance with (1) the terms of the Broker-Dealer Agreement relating to such Fund, in the case of any Fund listed on Exhibit A hereto or (2) the Basic Terms, in the case of any other Fund; provided, however, that:

2

(1) for purposes of any such Broker-Dealer Agreement or the Basic Terms, and notwithstanding any provision of any Broker-Dealer Agreement to the contrary, your address, telecopy number and telephone number for communications pursuant to such Broker-Dealer Agreement or the Basic Terms shall be as follows:





and the address, telecopy number and telephone number of the Auction Agent for communications pursuant to such Broker-Dealer or the Basic Terms shall be as follows:





(2) notwithstanding any provision of a Broker-Dealer Agreement to the contrary, except as otherwise set forth herein, your appointment as Broker-Dealer extends to each series of MMP, MPS or MuniPreferred issued by the Fund to which such Broker-Dealer Agreement relates.

(3) the text of Section 2.9 of each Broker-Dealer Agreement shall be deleted and the following shall be deemed to be inserted in its place:

(a) If any Existing Holder with respect to whom BD has submitted a Bid or Sell Order for shares of MMP, MPS or MuniPreferred of any series that was accepted in whole or in part fails to instruct its Agent Member to deliver the shares of MMP, MPS or MuniPreferred subject to such Bid or Sell Order against payment therefor, BD, if it knows the identity of such Agent Member, shall instruct such Agent Member to deliver such shares against payment therefor and, if such Agent Member fails to comply with such instructions, BD may deliver to the Potential Holder with respect to whom BD submitted a Bid for shares of MMP, MPS or MuniPreferred of such series that was accepted in whole or in part a number of shares of MMP, MPS or MuniPreferred of such series that is less

3

than the number of shares of MMP, MPS, or MuniPreferred of such series specified in such Bid to be purchased by such Potential Holder.

(b) Neither the Auction Agent nor the Fund shall have any responsibility or liability with respect to the failure of an Existing Holder or a Potential Holder or its respective Agent Member to deliver shares of MMP, MPS or MuniPreferred of any series or to pay for shares of MMP, MPS or MuniPreferred of any series sold or purchased pursuant to the Auction Procedures or otherwise.

(c) Notwithstanding any provision of the Auction Procedures or the Settlement Procedures to the contrary, in the event BD is an Existing Holder with respect to shares of a series of MMP, MPS or MuniPreferred and the Auction Procedures provide that BD shall be deemed to have submitted a Sell Order in an Auction with respect to such shares if BD fails to submit in Order in that Auction with respect to such shares, BD shall have no liability to any Person for failing to sell such shares pursuant to such a deemed Sell Order if (i) such shares were transferred by the beneficial owner thereof without notification of such transfer in compliance with the Auction Procedures or (ii) BD has informed the Auction Agent pursuant to Section 2.2(g) of this Agreement that, according to BD's records, BD believes it is not the Existing Holder of such shares.

(d) Notwithstanding any provision of the Auction Procedures or the Settlement Procedures to the contrary, in the event an Existing Holder of shares of a series of MMP, MPS or MuniPreferred with respect to whom a Broker-Dealer submitted a Bid to the Auction Agent for such shares that was accepted in whole or in part, or submitted or is deemed to have submitted a Sell Order for such shares that was accepted in whole or in part, fails to instruct its Agent Member to deliver such shares against payment therefor, partial deliveries of shares of MMP, MPS or MuniPreferred that have been made in respect of Potential Holders' Submitted Bids for shares of such series that have been accepted in whole or in part shall constitute good delivery to such Potential Holders.

(e) Notwithstanding the foregoing terms of this Section, any delivery or non-delivery of shares of MMP, MPS or MuniPreferred of any series which represents any departure from the results of an Auction for shares of such series, as determined by the Auction Agent, shall be of no effect for purposes of the registry of Existing Holders maintained by the Auction Agent pursuant to the Auction Agency Agreement unless and until the Auction Agent shall have been notified of such delivery or non-delivery.

(f) The Auction Agent shall have no duty or liability with respect to enforcement of this Section 2.9.

(4) a new Section 2.2(g) shall be added to each Broker-Dealer Agreement, to read as follows:

4

(g) The Auction Agent's registry of Existing Holders of shares of a series of MMP, MPS or MuniPreferred shall be conclusive and binding on BD. BD may inquire of the Auction Agent between 3:00 P.M. on the Business Day preceding an Auction for shares of a series of MMP, MPS or MuniPreferred and 9:30 A.M. on the Auction Date for such Auction to ascertain the number of shares of such series in respect of which the Auction Agent has determined BD to be an Existing Holder. If BD believes it is the Existing Holder of fewer shares of such series than specified by the Auction Agent in response to BD's inquiry, BD may so inform the Auction Agent of that belief. BD shall not, in its capacity as Existing Holder of shares of such series, submit Orders in such Auction in respect of shares of such series covering in the aggregate more than the number of shares of such series specified by the Auction Agent in response to BD's inquiry.

(5) a new sentence shall be added to the end of Section 2.2(d) of each Broker-Dealer Agreement, to read as follows:

Nothing contained herein shall require BD to submit an Order for any customer in any Auction.

You hereby acknowledge that, notwithstanding any provision of any Broker-Dealer Agreement or the Basic Terms to the contrary, the Fund may (a) upon five business days' notice to the Auction Agent and you, amend, alter or repeal any of the provisions contained in any Broker-Dealer Agreement or the Basic Terms, it being understood and agreed that you shall be deemed to have accepted any such amendment, alteration or repeal if, after the expiration of such five business day period, you submit an Order to the Auction Agent in respect of the shares of MMP, MPS, MuniPreferred of the Fund or Funds to which such amendment, alteration or repeal relates, and (b) upon two business days' notice to the Auction Agent and you, exclude you from participating as a Broker-Dealer in any particular Auction for any particular series of MMP, MPS or MuniPreferred.

This Acceptance Letter shall be deemed to form part of each Broker-Dealer Agreement and the Basic Terms.

Capitalized terms not defined in this Acceptance Letter shall have the meanings ascribed to them in the relevant Broker-Dealer Agreement or the Basic Terms, as the case may be.

If, however, the aggregate principal amount of the Securities exceeds $400 million, one certificate shall be issued with respect to each $400 million of principal amount and an additional certificate shall be issued with respect to any remaining principal amount. Each Security certificate shall bear the following legend:

Unless this certificate is presented by an authorized representative of The Depository Trust Company, a New York corporation ("DTC"), to Issuer or its agent for registration of transfer, exchange, or payment, and any certificate issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein.

2. Issuer: (a) understands that DTC has no obligation to, and will not, communicate to its participants ("Participants") or to any person having an interest in the Securities any information contained in the Security certificate(s); and (b) acknowledges that neither DTC's Participants nor any person having an interest in the Securities shall be deemed to have notice of the provisions of the Security certificate(s) by virtue of submission of such certificate(s) to DTC.

3. In the event of any solicitation of consents from or voting by holders of the Securities, Issuer shall establish a record date for such purposes (with no provision for revocation of consents or votes by subsequent holders) and shall send notice of such record date to DTC no fewer than 15 calendar days in advance of such record date. Notices to DTC pursuant to this Paragraph by telecopy shall be directed to DTC's Reorganization Department, Proxy Unit at (212) 855-5181 or (212) 855-5182. If the party sending the notice does not receive a telecopy receipt from DTC confirming that the notice has been received, such party shall telephone (212) 855-5202.

4. In the event of a full or partial redemption of the Securities, Issuer or Trust Company shall send a notice to DTC specifying: (a) the number of Securities to be redeemed; and (b) the date such notice is to be distributed to Security holders (the "Publication Date"). Such notice shall be sent to DTC by a secure means (e.g., legible telecopy, registered or certified mail, overnight delivery) in a timely manner designed to assure that such notice is in DTC's possession no later than the close of business on the business day before or, if possible, two business days before the Publication Date. Issuer or Trust Company shall forward such notice either in a separate secure transmission for each CUSIP number or in a secure transmission for multiple CUSIP numbers (if applicable) which includes a manifest or list of each CUSIP number submitted in that transmission. (The party sending such notice shall have a method to verify subsequently the use of such means and the timeliness of such notice.) The Publication Date shall be no fewer than 30 days nor more than 60 days prior to the redemption date. Notices to DTC pursuant to this Paragraph by telecopy shall be directed to DTC's Call Notification Department at (516) 227-4164 or (516) 227-4190.

5. In the event of an invitation to tender the Securities (including mandatory tenders, exchanges, and capital changes), notice by Issuer or Trust Company to Security holders specifying the terms of the tender and the Publication Date of such notice shall be sent to DTC by a secure means in the manner set forth in the preceding Paragraph. Notices to DTC pursuant to this Paragraph and notices of other corporate actions by telecopy shall be directed to DTC's Reorganization Department at (212) 855-5488. If the party sending the notice does not receive a telecopy receipt from DTC confirming that the notice has been received, such party shall telephone (212) 855-5290.

6. All notices and payment advices sent to DTC shall contain the CUSIP number of the Securities.

7. The Document indicates that the dividend rate for the Securities may vary from time to time. Absent other existing arrangements with DTC, Issuer or Trust Company shall give DTC notice of each such change in the dividend rate, on the same day that the new rate is determined, by telephoning DTC's Dividend Announcement Section at (212) 855-4550, or by telecopy sent to (212) 855-4555. Such verbal or telecopy notice shall be followed by prompt written confirmation sent by

a secure means (e.g., legible telecopy, registered or certified mail, overnight delivery) in a timely manner designed to assure that such notice is in DTC's possession no later than the close of business on the business day before or, if possible, two business days before the Publication Date. Issuer or Agent shall forward such notice either in a separate secure transmission for each CUSIP number or in a secure transmission for multiple CUSIP numbers (if applicable) which includes a manifest or list of each CUSIP number submitted in that transmission.

8. The Document indicates that each purchaser of Securities must sign a purchaser's letter which contains provisions restricting transfer of the Securities purchased. Issuer and Trust & Co. shall be entitled to all voting rights applicable to the Securities and to receive the full amount of all dividends, liquidation proceeds, and redemption proceeds payable with respect to the Securities, even if the credits of Securities to the DTC accounts of any DTC Participant result from transfers or failures to transfer in violation of the provisions of the purchaser's letter. Issuer and Trust Company acknowledge that DTC shall treat any Participant having Securities credited to its DTC accounts as entitled to the full benefits of ownership of such Securities. Without limiting the generality of the preceding sentence, Issuer and Trust Company acknowledge that DTC shall treat any Participant having Securities credited to its DTC accounts as entitled to receive dividends, distributions, and voting rights, if any, in respect of Securities and, subject to Paragraphs 12 and 13, to receive certificates evidencing Securities if such certificates are to be issued in accordance with Issuer's certificate of incorporation. (The treatment by DTC of the effects of the crediting by it of Securities to the accounts of Participants described in the preceding two sentences shall not affect the rights of Issuer, participants in auctions relating to the Securities, purchasers, sellers, or holders of Securities against any Participant.) DTC shall not have any responsibility to ascertain whether any transfer of Securities is made in accordance with the provisions of the purchaser's letter.

9. Issuer or Trust Company shall provide a written notice of dividend payment and distribution information to DTC as soon as the information is available. Issuer or Trust Company shall provide this information to DTC electronically, as previously arranged by Issuer or Trust Company and DTC, as soon as the information is available. If electronic transmission has not been arranged, absent any other arrangements between Issuer or Trust Company and DTC, such information shall be sent by telecopy to DTC's Dividend Department at
(212) 855-4555 or (212) 855-4556, and receipt of such notices shall be confirmed by telephoning (212) 855-4550. Notices to DTC pursuant to this Paragraph, by mail or by any other means, shall be addressed as indicated in Paragraph 7.

10. Dividend payments and distributions shall be received by Cede & Co., as nominee of DTC, or its registered assigns, in same-day funds no later than 2:30 p.m. (Eastern Time) on the payment date. Issuer shall remit by 1:00 p.m. (Eastern Time) on the payment date, dividend and distribution payments due Trust Company, or at such earlier time as may be required by Trust Company to guarantee that DTC shall receive payment in same-day funds no later than 2:30
p.m. (Eastern Time) on the payment date. Absent any other arrangements between Issuer or Trust Company and DTC, such funds shall be wired to the Dividend Deposit Account number that will be stamped on the signature page hereof at the time DTC executes this Letter of Representations.

11. Issuer or Trust Company shall provide DTC, no later than 12:00 noon (Eastern Time) on each payment date, automated notification of CUSIP-level detail. If the circumstances prevent the funds paid to DTC from equaling the dollar amount associated with the detail payments by 12:00 noon (Eastern Time), Issuer or Trust Company must provide CUSIP-level reconciliation to DTC no later than 2:30 p.m. (Eastern Time). Reconciliation must be provided by either automated means or written format. Such reconciliation notice, if sent by telecopy, shall be directed to DTC's Dividend Department at (212) 855-4633, and receipt of such reconciliation notice shall be confirmed by telephoning
(212) 855-4430.

12. Redemption payments shall be received by Cede & Co., as nominee of DTC, or its registered assigns, in same-day funds no later than 2:30 p.m. (Eastern Time) on the payment date. Issuer shall remit by 1:00 p.m. (Eastern Time) on the payment date all such redemption payments due Trust Company, or at such earlier time as required by Trust Company to guarantee that DTC shall receive payment in same-day funds no later that 2:30 p.m. (Eastern Time) on the payment date. Absent any other arrangements between Issuer or Trust Company and DTC, such funds shall be wired to the Redemption Deposit Account number that will be stamped on the signature page hereof at the time DTC executes this Letter of Representations.

13. Reorganization payments and CUSIP-level detail resulting from corporate actions (such as tender offers, remarketings, or mergers) shall be received by Cede & Co., as nominee of DTC, or its registered assigns, in same-day funds no later than 2:30 p.m. (Eastern Time) on the payment date. Issuer shall remit by 1:00 p.m. (Eastern Time) on the payment date all such reorganization payments due Trust Company, or at such earlier time as required by Trust Company to guarantee that DTC shall receive payment in same-day funds no later than 2:30 p.m. (Eastern Time) on the payment date. Absent any other arrangements between Issuer or Trust Company and DTC, such funds shall be wired to the Reorganization Deposit Account number that will be stamped on the signature page hereof at the time DTC executes this Letter of Representations.

14. DTC my direct Issuer or Trust Company to use any other number or address as the number or address to which notices or payments may be sent.

15. In the event of a redemption acceleration, or any similar transaction (e.g., tender made and accepted in response to Issuer's or Trust Company's invitation) necessitating a reduction in the number of Securities outstanding, or an advance refunding of part of the Securities outstanding DTC, in its discretion: (a) may request Issuer or Trust Company to issue and authenticate a new Security certificate; or (b) may make an appropriate notation on the Security certificate indicating the date and amount of such reduction in the number of Securities outstanding, except in the case of final

-5-

redemption, in which case the certificate will be presented to Issuer and Trust Company prior to payment, if required.

16. In the event that Issuer determines that beneficial owners of Securities shall be able to obtain certificated Securities, Issuer or Trust Company shall notify DTC of the availability of certificates. In such event, Issuer or Trust Company shall issue, transfer, and exchange certificates in appropriate amounts, as required by DTC and others.

17. DTC may discontinue providing its services as securities depository with respect to the Securities at any time by giving reasonable notice to Issuer or Trust Company (at which time DTC will confirm with Issuer or Trust Company the aggregate principal amount of Securities outstanding). Under such circumstances, at DTC's request, Issuer and Trust Company shall cooperate fully with DTC by taking appropriate action to make available one or more separate certificates evidencing Securities to any DTC Participant having Securities credited to its DTC accounts.

18. Issuer herby authorizes DTC to provide to Trust Company listings of Participants' holdings, known as Security Position Listings ("SPLs") with respect to the Securities from time to time at the request of Trust Company. Issuer also authorizes DTC, in the event of a partial redemption of Securities, to provide Trust Company, upon request, with the names of those Participants whose positions in Securities have been selected for redemption by DTC. DTC will use its best efforts to notify Trust Company of those Participants whose positions in Securities have been selected for redemption by DTC. Issuer authorizes and instructs Trust Company to provide DTC with such signatures, examples of signatures, and authorizations to act as may be deemed necessary or appropriate by DTC to permit DTC to discharge its obligations to its Participants and appropriate regulatory authorities. DTC charges a customary fee for such SPLs. This authorization, unless revoked by Issuer, shall continue with respect to the Securities while any Securities are on deposit at DTC, until and unless Trust Company shall no longer be acting. In such event, Issuer shall provide DTC with similar evidence, satisfactory to DTC, of the authorization of any successor thereto so to act. Requests for SPLs shall be directed to the Proxy Unit of DTC's Reorganization Department at (212) 855-5181 or (212) 855-5812. Receipt of such requests shall be confirmed by telephoning (212) 855-5202. Delivery by mail or by any other means, with respect to such SPL request, shall be directed to the address indicated in Paragraph 3.

19. Nothing herein shall be deemed to require Trust Company to advance funds on behalf of Issuer.

20. This Letter of Representations may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original, but all such counterparts together shall constitute but one and the same instrument.

21. This Letter of Representations shall be governed by, and construed in accordance with, the laws of the State of New York, without giving effect to principles of conflicts of law.

22. The sender of each notice delivered to DTC pursuant to this Letter of Representations is responsible for confirming that such notice was properly received by DTC.

23. Issuer recognizes that DTC does not in any way undertake to, and shall not have any responsibility to, monitor or ascertain the compliance of any transactions in the Securities with the following, as amended from time to time: (a) any exemptions from registration under the Securities Act of 1933;
(b) the Investment Company Act of 1940; (c) the Employee Retirement Income Security Act of 1974; (d) the Internal Revenue Code of 1986; (e) any rules of any self-regulatory organizations (as defined under the Securities Exchange Act of 1934); or (f) any other local, state, or federal laws or regulations thereunder.

24. Issuer and Trust Company shall comply with the applicable requirements stated in DTC's Operational Arrangements, as they may be amended from time to time. DTC's Operational Arrangements are posted on DTC's website at "www.DTC.org."

SAMPLE OFFERING DOCUMENT LANGUAGE
DESCRIBING BOOK-ENTRY-ONLY ISSUANCE
(Prepared by DTC-bracketed material may be applicable only to certain issues)

1. The Depository Trust Company ("DTC"), New York, NY, will act as securities depository for the securities (the "Securities"). The Securities will be issued as fully-registered securities registered in the name of Cede & Co. (DTC's partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered Security certificate will be issued for [each issuer of] the Securities, [each] in the aggregate principal amount of such issue, and will be deposited with DTC. [If, however, the aggregate principal amount of [any] issue exceeds $400 million, one certificate will be issued with respect to each $400 million of principal amount and an additional certificate will be issued with respect to any remaining principal amount of such issue.]

2. DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds securities that its participants ("Direct Participants") deposit with DTC. DTC also facilitates the settlement among Direct Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Direct Participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants include securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is owned by a number of its Direct Participants and by the New York Stock Exchange, Inc., the American Stock Exchange LLC, and the National Association of Securities Dealers, Inc. Access to the DTC system is also available to others such as securities brokers and dealers, banks, and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants"). The Rules applicable to DTC and its Direct and Indirect Participants are on file with the Securities and Exchange Commission.

3. Purchases of Securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the Securities on DTC's records. The ownership interest of each actual purchaser of each Security ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchase, but Beneficial Owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Securities are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in Securities, except in the event that use of the book-entry system for the Securities is discontinued.

-10-

4. To facilitate subsequent transfers, all Securities deposited by Direct Participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of Securities with DTC and their registration in the name of Cede & Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Securities; DTC's records reflect only the identity of the Direct Participants to whose accounts such Securities are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

5. Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. [Beneficial Owners of Securities may wish to take certain steps to augment transmission to them of notices of significant events with respect to the Securities, such as redemptions, tenders, defaults, and proposed amendments to the security documents. Beneficial Owners of Securities may wish to ascertain that the nominee holding the Securities for their benefit has agreed to obtain and transmit notices to Beneficial Owners, or in the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of the notices be provided directly to them.]

[6. Redemption notices shall be sent to DTC. If less than all of the Securities within an issue are being redeemed, DTC's practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.]

7. Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the Securities. Under its usual procedures, DTC mails an Omnibus Proxy to Issuer as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct Participants to whose accounts the Securities are credited on the record date (identified in a listing attached to the Omnibus Proxy).

8. Redemption proceeds, distributions, and dividend payments on the Securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit Direct Participants' accounts, upon DTC's receipt of funds and corresponding detail information from Issuer or Agent on payable date in accordance with their respective holdings shown on DTC's records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such Participant and not of DTC, Agent, or Issuer, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and dividends to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of Issuer or Agent, disbursement of such payments to Direct Participants shall be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct and Indirect Participants.

-11-

[9. A Beneficial owner shall give notice to elect to have the Securities purchased or tendered, through its Participant, to [Tender/Remarketing] Agent, and shall effect delivery of such Securities by causing the Direct Participant to transfer the Participant's interest in the Securities, on DTC's records, to
[Tender/Remarketing] Agent. The requirement for physical delivery of Securities in connection with an optional tender or a mandatory purchase will be deemed satisfied when the ownership rights in the Securities are transferred by Direct Participants on DTC's records and followed by a book-entry credit of tendered Securities to [Tender/Remarketing] Agent's DTC account.]

10. DTC may discontinue providing its services as securities depository with respect to the Securities at any time by giving reasonable notice to Issuer or Agent. Under such circumstances, in the event that a successor securities depository is not obtained, Security certificates are required to be printed and delivered.

11. Issuer may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depository). In that event, Security certificates will be printed and delivered.

12. The information in this section concerning DTC and DTC's book-entry system has been obtained from sources that Issuer believes to be reliable, but Issuer takes no responsibility for the accuracy thereof.

We are acting as counsel to Nuveen Municipal High Income Opportunity Fund, a Massachusetts business trust (the "Fund"), in connection with the Fund's filing of a registration statement on Form N-2 (the "Registration Statement") with the Securities and Exchange Commission covering the registration and proposed issuance of 3,000, 1,600 and 1,600 shares, par value $0.01 per share, of Series M, Series T and Series W, respectively of its Municipal Auction Rate Cumulative Preferred Shares ("MuniPreferred"), liquidation preference of $25,000 per share (the "Shares"). In that capacity, we have examined such corporate records, certificates and other documents, and have made such other factual and legal investigations as we have deemed necessary and appropriate for the purposes of this opinion. Insofar as this opinion pertains to matters governed by the laws of the Commonwealth of Massachusetts, we are relying, with your consent, solely upon the opinion of Bingham McCutchen LLP dated January 14, 2004, and the opinions expressed herein are subject to the assumptions, limitations and qualification conformed therein.

We have assumed that the Registration Statement, the underwriting agreement relating to the Fund's Shares and the Statement Establishing and Fixing the Rights and Preferences of Municipal Auction Rate Cumulative Preferred Shares (the "Statement") relating to the Fund's Shares will be duly completed, executed and delivered and in accordance with the resolutions of the Trustees attached to a Certificate of the Secretary of the Fund, certifying as to, and attaching copies of, the Fund's Declaration of Trust ("Declaration"), Statement, By-Laws, and certain resolutions adopted by the Trustees of the Fund and that the Statement will be duly filed with the Office of the Secretary of the Commonwealth of Massachusetts.

Based upon the foregoing, it is our opinion that:

(1) The Fund has been formed and is validly existing under the Fund's Declaration and the laws of the Commonwealth of Massachusetts as a voluntary association

with transferable shares of beneficial interest commonly referred to as a "Massachusetts business trust."

(2) The Shares, when issued and sold in accordance with the Fund's Declaration, Statement and By-Laws and for the consideration described in the Underwriting Agreement, will be legally issued, fully paid and non-assessable, except that, as set forth in the Registration Statement, shareholders of the Fund may under certain circumstances be held personally liable for its obligations.

We hereby consent to the filing of this opinion as Exhibit l.1 to the Registration Statement and to the reference to us under the caption "Legal Opinions" in the prospectus contained in the Registration Statement.

RE: Nuveen Municipal High Income Opportunity Fund

Ladies and Gentlemen:

We have acted as special Massachusetts counsel to Nuveen Municipal High Income Opportunity Fund, a Massachusetts business trust (the "Fund"), in connection with the Fund's Registration Statement on Form N-2 filed with the Securities and Exchange Commission (the "Commission") on December 30, 2003 (the "Initial Filing") as such Registration Statement is proposed to be amended by Pre-Effective Amendment No. 1 thereto to be filed with the Commission on or about January 14, 2004 (as proposed to be amended, the "Registration Statement") with respect to 3,000 shares Series M, 1,600 shares Series T and 1,600 shares Series W the Fund's MuniPreferred shares, with a liquidation preference of $25,000 per share (the "Shares").

In connection with the furnishing of this opinion, we have examined the following documents:

We have assumed that the Amendment will be duly filed with the Commission in substantially the form of the printer's proof referred to in (f) above, that the Statement will be duly completed, executed and delivered in substantially the form included in such printer's proof and in accordance with the resolutions of the Trustees attached to the certificate referred to in (d) above, and that the Statement will be duly filed with the office of the Secretary of the Commonwealth of Massachusetts.

We understand that all of the foregoing assumptions and limitations are acceptable to you.
