Portfolio Contents. Under normal circumstances, the Fund will invest at least 80% of its net assets in a portfolio of municipal bonds that are exempt from regular federal income tax, and the alternative minimum tax applicable to individuals and that are covered by insurance guaranteeing the timely payment of principal and interest therein. The Fund may at all times invest up to 20% of its net assets in uninsured municipal bonds backed by an escrow or trust account containing sufficient U.S. Government or U.S. Government agency securities to ensure timely payment of principal and interest, or other municipal bonds that are investment grade quality. The Fund cannot assure you that it will achieve its investment objectives.

No Prior History. Because the Fund is newly organized, its common shares have no history of public trading. Shares of closed-end investment companies frequently trade at a discount from their net asset value. This risk may be greater for investors expecting to sell their shares in a relatively short period after completion of the public offering. The common shares have been approved for listing on the , subject to notice of issuance. The trading or "ticker" symbol of the common shares is " ".

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 to understand the offering fully.

The Fund..............   Nuveen Insured Tax-Free Advantage Municipal Fund (the
                           "Fund") is a newly organized, diversified,
                           closed-end management investment company. See "The
                           Fund."

The Offering..........   The Fund is offering     common shares of beneficial
                           interest at $15.00 per share through a group of
                           underwriters (the "Underwriters") led by Nuveen
                           Investments ("Nuveen") and     . The common shares
                           of beneficial interest are called "Common Shares" in
                           the rest of this Prospectus. You must purchase at
                           least 100 Common Shares in this offering. The Fund
                           has given the Underwriters an option to purchase up
                           to     additional Common Shares to cover orders in
                           excess of     Common Shares. See "Underwriting."
                           Nuveen has agreed to pay (i) all organizational
                           expenses and (ii) offering costs (other than sales
                           load) that exceed $0.03 per Common Share.

Investment Objectives.   The Fund's investment objectives are to provide
                           current income exempt from regular federal income
                           tax and the alternative minimum tax applicable to
                           individuals and enhance portfolio value relative to
                           the municipal bond market by investing in tax-exempt
                           municipal bonds that the Fund's investment adviser
                           believes are underrated or undervalued or that
                           represent municipal market sectors that are
                           undervalued. Under normal circumstances, the Fund
                           will invest at least 80% of its net assets in a
                           portfolio of municipal bonds that:
                             .  are exempt from regular federal income tax;
                             .  do not pay interest subject to the federal
                                alternative minimum tax applicable to
                                individuals; and
                             .  are covered by insurance guaranteeing the
                                timely payment of principal and interest
                                thereon.

                           This insurance does not protect the market value of
                           portfolio holdings or the net asset value of the
                           Fund.

                         Under normal circumstances, the Fund expects to be
                           fully invested (at least 95% of its assets) in such
                           tax-exempt municipal bonds. The Fund will not invest
                           in bonds that pay interest subject to the federal
                           alternative minimum tax applicable to individuals
                           ("AMT Bonds").

                         The Fund may at all times invest up to 20% of its net
                           assets in (i) uninsured municipal bonds that are
                           backed by an escrow or trust account containing
                           sufficient U.S. Government or U.S. Government agency
                           securities to ensure timely payment of principal and
                           interest, or (ii) other municipal bonds that at the
                           time of investment are investment grade quality. An
                           investment grade quality bond is a bond rated within
                           the four highest grades (Baa or BBB or better by

                           McGraw-Hill Companies ("S&P") or Fitch Ratings

                           comparable quality by the Fund's investment adviser.
                           The Fund cannot assure you that it will attain its
                           investment objectives. See "The Fund's Investments."

Special Considerations   Distributions of ordinary taxable income (including
                           any net short-term capital gain) will be taxable to
                           shareholders as ordinary income, and capital gain
                           dividends will be subject to capital gains taxes.
                           See "Tax Matters."

Proposed Offering of
MuniPreferred(R) Shares  Subject to market conditions, approximately one to
                           three months after completion of this offering, the
                           Fund intends to offer preferred shares of beneficial
                           interest ("MuniPreferred Shares") representing
                           approximately 35% of the Fund's capital after their
                           issuance. The issuance of MuniPreferred Shares will
                           leverage your investment in Common Shares. Leverage
                           involves special risks. There is no assurance that
                           the Fund will issue MuniPreferred Shares or that, if
                           issued, the Fund's leveraging strategy will be
                           successful. See "Risks--Leverage Risk." The money
                           the Fund obtains by selling the MuniPreferred Shares
                           will be invested in long-term municipal bonds, which
                           generally will pay fixed rates of interest over the
                           life of the bond. The MuniPreferred Shares will pay
                           dividends based on shorter-term rates, which will be
                           reset frequently. So long as the rate of return, net
                           of applicable Fund expenses, on the long-term bonds
                           purchased by the Fund exceeds MuniPreferred Share
                           dividend rates as reset periodically, the investment
                           of the proceeds of the MuniPreferred Shares will
                           generate more income than will be needed to pay
                           dividends on the MuniPreferred Shares. If so, the
                           excess will be used to pay higher dividends to
                           holders of Common Shares ("Common Shareholders").
                           However, the Fund cannot assure you that the
                           issuance of MuniPreferred Shares will result in a
                           higher yield on your Common Shares. Once
                           MuniPreferred Shares are issued, the net asset value
                           and market price of the Common Shares and the yield
                           to Common Shareholders will be more volatile. See
                           "MuniPreferred Shares and Leverage" and "Description
                           of Shares--MuniPreferred Shares."

Investment Adviser....   Nuveen Advisory Corp. ("Nuveen Advisory") will be the
                           Fund's investment adviser. Nuveen Advisory will
                           receive an annual fee, payable monthly, in a maximum
                           amount equal to .65% of the Fund's average daily net
                           assets (including assets attributable to any
                           MuniPreferred Shares that may be outstanding
                           (sometimes referred to herein as "Managed Assets")),
                           with lower fee levels for assets that exceed $125
                           million. Nuveen Advisory has contractually agreed to

                                      5

                           reimburse the Fund for fees and expenses in the
                           amount of .32% of average daily Managed Assets of
                           the Fund for the first five full years of the Fund's
                           operations (through     , 2007), and for a declining
                           amount for an additional three years (through     ,
                           2010). Nuveen Advisory is a wholly owned subsidiary
                           of The John Nuveen Company. See "Management of the
                           Fund."

Distributions.........   Commencing with the Fund's first dividend, the Fund
                           intends to make regular monthly cash distributions
                           to Common Shareholders at a level rate (stated in
                           terms of a fixed cents per Common Share dividend
                           rate) based on the projected performance of the
                           Fund. The Fund's ability to maintain a level Common
                           Share dividend rate will depend on a number of
                           factors, including dividends payable on the
                           MuniPreferred Shares. As portfolio and market
                           conditions change, the rate of dividends on the
                           Common Shares and the Fund's dividend policy could
                           change. Over time, the Fund will distribute all of
                           its net investment income (after it pays accrued
                           dividends on any outstanding MuniPreferred Shares).
                           In addition, at least annually, the Fund intends to
                           distribute net capital gain and taxable ordinary
                           income, if any, to you so long as the net capital
                           gain and taxable ordinary income are not necessary
                           to pay accrued dividends on, or redeem or liquidate,
                           any MuniPreferred Shares. Your initial distribution
                           is expected to be declared approximately 45 days,
                           and paid approximately 60 to 90 days, from the
                           completion of this offering, depending on market
                           conditions. You may elect to automatically reinvest
                           some or all of your distributions in additional
                           Common Shares under the Fund's Dividend Reinvestment

Listing...............   The Common Shares have been approved for listing on
                           the       , subject to notice of issuance. See
                           "Description of Shares--Common Shares." The trading
                           or "ticker" symbol of the Common Shares is "    ."
                           Because of this exchange listing, the Fund may
                           sometimes be referred to in public communications as
                           a "closed-end exchange-traded fund" or
                           "exchange-traded fund."

Custodian.............   State Street Bank and Trust Company will serve as
                           custodian of the Fund's assets. See "Custodian and
                           Transfer Agent."

Market Price of Shares   Shares of closed-end investment companies frequently
                           trade at prices lower than net asset value. Shares
                           of closed-end investment companies like the Fund
                           that invest predominately in investment grade
                           municipal bonds have during some periods traded at
                           prices higher than net asset value and have during
                           other periods traded at prices lower than net asset
                           value. The Fund cannot assure you that Common Shares
                           will trade at a price higher than net asset value in
                           the future. Net asset value will be reduced
                           immediately following the offering by the sales load
                           and the amount of organization and offering expenses
                           paid by the Fund. See "Use of Proceeds." In

                           addition to net asset value, market price may be
                           affected by such factors as dividend levels (which
                           are in turn affected by expenses), call protection,
                           dividend stability, portfolio credit quality and
                           liquidity and market supply and demand. See
                           "MuniPreferred Shares and Leverage," "Risks,"
                           "Description of Shares," "Repurchase of Fund Shares;
                           Conversion to Open-End Fund" and the Statement of
                           Additional Information under "Repurchase of Fund
                           Shares; Conversion to Open-End Fund." The Common
                           Shares are designed primarily for long-term
                           investors, and you should not view the Fund as a
                           vehicle for trading purposes.

Special Risk
Considerations........   No Operating History.  The Fund is a newly organized,
                           diversified, closed-end management investment
                           company with no history of operations.

                         Interest Rate Risk.  Generally, when market interest
                           rates fall, bond prices rise, and vice versa.
                           Interest rate risk is the risk that the municipal
                           bonds in the Fund's portfolio will decline in value
                           because of increases in market interest rates. The
                           prices of longer-term bonds fluctuate more than
                           prices of shorter-term bonds as interest rates
                           change. Conversely, the values of lower-rated and
                           comparable unrated debt securities are less likely
                           than those of investment grade and comparable
                           unrated debt securities to fluctuate inversely with
                           changes in interest rates. Because the Fund will
                           invest primarily in long-term bonds, the Common
                           Share net asset value and market price per share
                           will fluctuate more in response to changes in market
                           interest rates than if the Fund invested primarily
                           in shorter-term bonds. The Fund's use of leverage,
                           as described below, will tend to increase Common
                           Share interest rate risk. See "Risks--Interest Rate
                           Risk."

                         Credit Risk.  Credit risk is the risk that one or more
                           municipal bonds in the Fund's portfolio will decline
                           in price, or fail to pay interest or principal when
                           due, because the issuer of the bond experiences a
                           decline in its financial status.

                         Leverage Risk.  The use of leverage through the
                           issuance of MuniPreferred Shares creates an
                           opportunity for increased Common Share net income
                           and returns, but also creates special risks for
                           Common Shareholders. There is no assurance that the
                           Fund's leveraging strategy will be successful. It is
                           anticipated that MuniPreferred dividends will be
                           based on shorter-term municipal bond rates of return
                           (which would be redetermined periodically, pursuant
                           to an auction process), and that the Fund will
                           invest the proceeds of the MuniPreferred Shares
                           offering in long-term, typically fixed rate,
                           municipal bonds. So long as the Fund's municipal
                           bond portfolio provides a higher rate of return (net
                           of Fund expenses) than the MuniPreferred dividend
                           rate, as reset periodically, the leverage

                                      7

                           will cause Common Shareholders to receive a higher
                           current rate of return than if the Fund were not
                           leveraged. If, however, long and/or short-term rates
                           rise, the MuniPreferred dividend rate could exceed
                           the rate of return on long-term bonds held by the
                           Fund that were acquired during periods of generally
                           lower interest rates, reducing return to Common
                           Shareholders. In addition, the Fund will pay
                           (and Common Shareholders will bear) any costs and
                           expenses relating to the issuance and ongoing
                           maintenance of MuniPreferred Shares (for example,
                           distribution related expenses such as a
                           participation fee paid at what the Fund expects will
                           be an annual rate of 0.25% of MuniPreferred Share
                           liquidation preference to broker-dealers
                           participating in MuniPreferred Share auctions).

                           Leverage creates two major types of risks for Common
                           Shareholders:

                            .   the likelihood of greater volatility of net
                                asset value and market price of Common Shares,
                                because changes in the value of the Fund's bond
                                portfolio (including bonds bought with the
                                proceeds of the MuniPreferred Shares offering)
                                are borne entirely by the Common Shareholders;
                                and

                            .   the possibility either that Common Share income
                                will fall if the MuniPreferred dividend rate
                                rises, or that Common Share income will
                                fluctuate because the MuniPreferred dividend
                                rate varies.

See "Risks--Leverage Risk."

Municipal Bond Market Risk. The amount of public information available about the municipal bonds 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 bonds 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 bonds at attractive prices. See "Risks--Municipal Bond Market Risk."

Municipal Bond Insurance. In the event Moody's, S&P or Fitch (or all of them) should downgrade its assessment of the claims-paying ability of a particular insurer, it (or they) could also be expected to downgrade the ratings assigned to municipal bonds insured by such insurer, and municipal bonds insured under Portfolio Insurance (as defined below) issued by such insurer also would be of reduced quality in the portfolio of the Fund. Any such downgrade could have an adverse impact on the net asset value and market price of the Common Shares.

In addition, the Fund may be subject to certain restrictions on investments imposed by guidelines of the insurance companies

8

issuing Portfolio Insurance. The Fund does not expect these guidelines to prevent Nuveen Advisory from managing the Fund's portfolio in accordance with the Fund's investment objective and policies.

Anti-Takeover Provisions. The Fund's Declaration of Trust (the "Declaration") includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to open-end status. The provisions of the Declaration described above could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares. See "Certain Provisions in the Declaration of Trust" and "Risks--Anti-Takeover Provisions."

(1)Nuveen has agreed to pay offering costs (other than sales load) that exceed $0.03 per Common Share.

(2)If the Fund offers MuniPreferred Shares, costs of that offering, estimated to be approximately % of the total amount of the MuniPreferred Share offering, will effectively be borne by the Common Shareholders and result in a reduction of the net asset value of the Common Shares. Assuming the issuance of MuniPreferred Shares in the amount equal to 35% of the Fund's total capital (after issuance), those offering costs are estimated to be approximately $ per Common Share ( % of the offering price).

(3)You will be charged a $2.50 service charge and pay brokerage charges if you direct State Street Bank and Trust Company, as agent for the Common Shareholders (the "Plan Agent") to sell your Common Shares held in a dividend reinvestment account.

(4)Stated as percentages of net assets attributable to Common Shares. Assuming no issuance of MuniPreferred Shares, the Fund's expenses would be estimated to be as follows:

                                                                        Percentage of Net
                                                                       Assets Attributable

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

(5)Nuveen Advisory has contractually agreed to reimburse the Fund for fees and expenses in the amount of .32% of average daily Managed Assets for the first 5 full years of the Fund's operations, .24% of average daily Managed Assets in year 6, .16% in year 7 and .08% in year 8. Assuming the

10

issuance of MuniPreferred Shares in an amount equal to 35% of the Fund's total assets (including the amount obtained from leverage) and calculated as a percentage of net assets attributable to Common Shares, those amounts would be % for the first 5 years, % in year 6, % in year 7 and % in year 8. Without the reimbursement, "Total Net Annual Expenses" would be estimated to be 1.38% of average daily net assets attributable to Common Shares (or, assuming no issuance of MuniPreferred Shares, % of average daily net assets).

The purpose of the table above is to help you understand all fees and expenses that you, as a Common Shareholder, would bear directly or indirectly. The expenses shown in the table are based on estimated amounts for the Fund's first year of operations and assume that the Fund issues approximately Common Shares. See "Management of the Fund" and "Dividend Reinvestment Plan."

The following example illustrates the expenses (including the sales load of $45, estimated offering expenses of this offering of $2 and the estimated MuniPreferred Share offering costs assuming MuniPreferred Shares are issued representing 35% of the Fund's total capital (after issuance) of $ ) that you would pay on a $1,000 investment in Common Shares, assuming (1) total net annual expenses of % of net assets attributable to Common Shares in years 1 through 5, increasing to % in years 9 and 10 and (2) a 5% annual return:/(1)/

1 Year 3 Years 5 Years 10 Years/(2)/

$ $ $ $

The example should not be considered a representation of future expenses. Actual expenses may be higher or lower.
(1)The example assumes that the estimated Other Expenses set forth in the Annual Expenses table are accurate, that fees and expenses increase as described in note 2 below and that all dividends and distributions are reinvested at Common Share net asset value. Actual expenses may be greater or less than those assumed. Moreover, the Fund's actual rate of return may be greater or less than the hypothetical 5% return shown in the example.
(2)Assumes reimbursement of fees and expenses of .24% of average daily Managed Assets in year 6, .16% in year 7 and .08% in year 8. Nuveen Advisory has not agreed to reimburse the Fund for any portion of its fees and expenses beyond , 2010. See footnote 5 above and "Management of the Fund--Investment Management Agreement."

THE FUND

The Fund is a newly organized, diversified, closed-end management investment company registered under the Investment Company Act of 1940 (the 1940 Act). The Fund was organized as a Massachusetts business trust on April 9, 2002, pursuant to a Declaration governed by the laws of the Commonwealth of Massachusetts. As a newly organized entity, the Fund has no operating history. The Fund's principal office is located at 333 West Wacker Drive, Chicago, Illinois 60606, and its telephone number is (800) 257-8787.

USE OF PROCEEDS

The net proceeds of the offering of Common Shares will be approximately $ ($ if the Underwriters exercise the over-allotment option in full) after payment of the estimated organization and offering costs. Nuveen has agreed to pay (i) all organizational expenses and (ii) offering costs (other than sales load) that exceed $0.03 per Common Share. The Fund will invest the net proceeds of the offering in accordance with the Fund's investment objectives and policies as stated below. It is presently anticipated that the Fund will be able to invest substantially all of the net proceeds in municipal bonds that meet those investment objectives and policies within three months after the completion of the offering. Pending such investment, it is anticipated that the proceeds will be invested in short-term, tax-exempt securities.

THE FUND'S INVESTMENTS

Investment Objectives and Policies

The Fund's investment objectives are:

. to provide current income exempt from regular federal income tax, and the alternative minimum tax applicable to individuals; and

. to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal bonds that Nuveen Advisory believes are underrated or undervalued or that represent municipal market sectors that are undervalued.

Underrated municipal bonds are those whose ratings do not, in Nuveen Advisory's opinion, reflect their true creditworthiness. Undervalued municipal bonds are bonds that, in Nuveen Advisory's opinion, are worth more than the value assigned to them in the marketplace. Nuveen Advisory may at times believe that bonds associated with a particular municipal market sector (for example, electric utilities), or issued by a particular municipal issuer, are undervalued. Nuveen Advisory may purchase such a bond for the Fund's portfolio because it represents a market sector or issuer that Nuveen Advisory considers undervalued, even if the value of the particular bond appears to be consistent with the value of similar bonds. Municipal bonds of particular types (e.g., hospital bonds, industrial revenue bonds or bonds issued by a particular municipal issuer) may be undervalued because there is a temporary excess of supply in that market sector, or because of a general decline in the market price of municipal bonds of the market sector for reasons that do not apply to the particular municipal bonds that are considered undervalued. The Fund's investment in underrated or undervalued municipal bonds will be based on Nuveen Advisory's belief that their yield is higher than that available on bonds bearing equivalent levels of interest rate risk, credit risk and other forms of risk, and that their prices will ultimately rise (relative to the market) to reflect their true value. The Fund attempts to increase its portfolio value relative to the municipal bond market by prudent selection of municipal bonds regardless of the direction the market may move. Any capital appreciation realized by the Fund will generally result in the distribution of taxable capital gains to Common Shareholders.

12

Under normal market conditions, the Fund will invest at least 80% of its net assets in a portfolio of municipal bonds that:

. are exempt from regular federal income tax;

. do not pay interest subject to the federal alternative minimum tax applicable to individuals; and

. are covered by insurance guaranteeing the timely payment of principal and interest thereon.

This insurance does not protect the market value of portfolio holdings or the net asset value of the Fund.

Under normal market conditions, the Fund expects to be fully invested (at least 95% of its assets) in such tax-exempt municipal bonds. The Fund will not invest in AMT Bonds. For more information, see the Statement of Additional Information.

The Fund may at all times invest up to 20% of its net assets in (i) uninsured municipal bonds that are backed by an escrow or trust account containing sufficient U.S. Government or U.S. Government agency securities to ensure timely payment of principal and interest, or (ii) other municipal bonds that, at the time of investment, are investment grade quality. Investment grade quality means that such bonds are rated, at the time of investment, by all NRSROs that rate the bond within the four highest grades (Baa or BBB or better by Moody's, S&P or Fitch) or are unrated but judged to be of comparable quality by Nuveen Advisory. The foregoing credit quality policy applies 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 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 bonds 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 bonds of the types in which the Fund may invest directly. See "--Other Investment Companies."

Each insured municipal bond that the Fund acquires will be (1) covered by an insurance policy applicable to a specific security and obtained by the issuer of the security or a third party at the time of original issuance ("Original Issue Insurance"), (2) covered by an insurance policy applicable to a specific security and obtained by the Fund or a third party subsequent to the time of original issuance ("Secondary Market Insurance"), or (3) covered by a master municipal insurance policy purchased by the Fund ("Portfolio Insurance"). The Fund, as a non-fundamental policy that can be changed by the Board of Trustees, only will buy Portfolio Insurance from insurers whose claims-paying ability Moody's rates "Aaa" or S&P or Fitch rates "AAA."

The credit quality of companies that provide insurance on bonds will affect the value of those bonds. 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. Insurance generally will be obtained from insurers with a claims-paying ability rated Aaa by Moody's or AAA by S&P or Fitch. The insurance feature does not guarantee the market value of the insured obligations or the net asset value of the Common Shares.

The Fund may at all times invest up to 20% of its net assets in uninsured municipal bonds that are entitled to the benefit of an escrow or trust account that contains securities issued or guaranteed by the

13

U.S. Government or U.S. Government agencies backed by the full faith and credit of the United States, and sufficient in amount to ensure the payment of interest and principal on the original interest payment and maturity dates ("collateralized obligations"). These collateralized obligations generally will not be insured and will include, but are not limited to, municipal bonds that have been (1) advance refunded where the proceeds of the refunding have been used to buy U.S. Government or U.S. Government agency securities that are placed in escrow and whose interest or maturing principal payments, or both, are sufficient to cover the remaining scheduled debt service on that municipal bond; or (2) issued under state or local housing finance programs that use the issuance proceeds to fund mortgages that are then exchanged for U.S. Government or U.S. Government agency securities and deposited with a trustee as security for those municipal bonds. These collaterlized obligations are normally regarded as having the credit characteristics of the underlying U.S. Government or U.S. Government agency securities.

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 policies 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 tax, and the alternative minimum tax applicable to individuals. For more information, see the Statement of Additional Information. Likewise, the Fund may deviate from its normal investment policies and invest in taxable fixed-income and equity securities of an issuer of minicipal bonds that the Fund already owns for the purpose of acquiring control of that issuer when Nuveen Advisory determines that such investment should enable the Fund to better maximize the value of its existing investment. See "--Miscellaneous Investments."

The Fund cannot change its (i) fundamental investment restrictions set forth in the Statement of Additional Information or (ii) policy to invest 80% of its Managed Assets in a portfolio of municipal bonds that (a) are exempt from regular federal income tax and (b) do not pay interest subject to the federal alternative minimum tax applicable to individuals 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 Shares--MuniPreferred Shares--Voting Rights" and the Statement of Additional Information under "Description of Shares--MuniPreferred Shares--Voting Rights" for additional information with respect to the voting rights of holders of MuniPreferred Shares. Other than as noted above, the investment objectives and policies of the Fund may be changed by the Board without shareholder action.

Municipal Bonds

Municipal bonds 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 bonds may also be issued for private activities, such as housing, medical

14

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 also may purchase municipal bonds that represent lease obligations. These carry special risks because the issuer of the bonds may not be obligated to appropriate money annually to make payments under the lease. In order to reduce this risk, the Fund will only purchase municipal bonds representing lease obligations where Nuveen Advisory believes the issuer has a strong incentive to continue making appropriations until maturity.

The municipal bonds 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 or 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 federal income tax and the alternative minimum tax applicable to individuals. It is a fundamental policy of the Fund that its investment in municipal bonds whose interest is not taxable under regular federal income tax or the alternative minimum tax applicable to individuals will, under normal circumstances, comprise at least 80% of the Fund's Managed Assets.

Other than as permitted during this Invest-up Period and subject to board approval, the Fund may invest up to 20% of its net assets (together with taxable temporary investments) in AMT Bonds, although it has no present intention to do so. As a result, a portion of the income produced by the Fund may be includable in the calculation of federal alternative minimum taxable income for individuals. In addition, interest on all municipal bonds is taken into account to determine whether a corporation is subject to the federal alternative minimum tax. See "Tax Matters." It is a fundamental policy of the Fund that its investments in municipal bonds whose interest is not taxable under regular federal income tax or the federal alternative minimum tax will, under normal circumstances, comprise at least 80% of the Fund's Managed Assets.

The yields on municipal bonds 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 bonds 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 bonds with long-term maturities in order to maintain a weighted average maturity of 15-30 years, but the weighted average maturity of obligations held by the Fund may be shortened, depending on market conditions.

Municipal Bond Insurance

Each insured municipal bond the Fund acquires will be covered by Original Issue Insurance, Secondary Market Insurance or Portfolio Insurance. The Fund expects initially to emphasize investments in municipal bonds insured under bond-specific insurance policies (i.e., Original Issue or Secondary Market Insurance). The Fund may obtain Portfolio Insurance from the insurers described in Appendix C to the Statement of Additional Information. The Fund, as a non-fundamental policy that can be changed by the Board of Trustees, will only obtain policies of Portfolio Insurance issued by insurers whose claims-paying ability is rated "Aaa" by Moody's or "AAA" by S&P or Fitch. There is no limit on the percentage of the Fund's assets that may be invested in municipal bonds insured by any one insurer.

15

Municipal bonds covered by Original Issue Insurance or Secondary Market Insurance are themselves typically assigned a rating of "Aaa" or "AAA", as the case may be, by virtue of the rating of the "Aaa" or "AAA" claims-paying ability of the insurer and would generally be assigned a lower rating if the ratings were based primarily upon the credit characteristics of the issuer without regard to the insurance feature. By way of contrast, the ratings, if any, assigned to municipal bonds insured under Portfolio Insurance will be based primarily upon the credit characteristics of the issuer, without regard to the insurance feature, and generally will carry a rating that is below "Aaa" or "AAA." While in the portfolio of the Fund, however, a municipal bond backed by Portfolio Insurance will effectively be of the same credit quality as a municipal bond issued by an issuer of comparable credit characteristics that is backed by Original Issue Insurance or Secondary Market Insurance.

The Fund's policy of investing in municipal bonds insured by insurers whose claims-paying ability is rated "Aaa" or "AAA" applies only at the time of purchase of a security, and the Fund will not be required to dispose of the securities in the event Moody's, S&P or Fitch, as the case may be, downgrades its assessment of the claims-paying ability of a particular insurer or the credit characteristics of a particular issuer. In this connection, it should be noted that in the event Moody's, S&P or Fitch (or all of them) should downgrade its assessment of the claims-paying ability of a particular insurer, it (or they) could also be expected to downgrade the ratings assigned to municipal bonds insured by such insurer, and municipal bonds insured under Portfolio Insurance issued by such insurer also would be of reduced quality in the portfolio of the Fund. Moody's, S&P and Fitch continually assess the claims-paying ability of insurers and the credit characteristics of issuers, and there can be no assurance that they will not downgrade their assessments subsequent to the time the Fund purchases securities.

The value of municipal bonds covered by Portfolio Insurance that are in default or in significant risk of default will be determined by separately establishing a value for the municipal bond and a value for the Portfolio Insurance.

Original Issue Insurance. Original Issue Insurance is purchased with respect to a particular issue of municipal bonds by the issuer thereof or a third party in conjunction with the original issuance of such municipal bonds. Under this insurance, the insurer unconditionally guarantees to the holder of the municipal bond the timely payment of principal and interest on such obligations when and as these payments become due but not paid by the issuer, except that in the event of the acceleration of the due date of the principal by reason of mandatory or optional redemption (other than acceleration by reason of a mandatory sinking fund payment), default or otherwise, the payments guaranteed may be made in the amounts and at the times as payment of principal would have been due had there not been any acceleration. The insurer is responsible for these payments less any amounts received by the holder from any trustee for the municipal bond issuer or from any other source. Original Issue Insurance does not guarantee payment on an accelerated basis, the payment of any redemption premium (except with respect to certain premium payments in the case of certain small issue industrial development and pollution control municipal bonds), the value of the Fund's shares, the market value of municipal bonds, or payments of any tender purchase price upon the tender of the municipal bonds. Original Issue Insurance also does not insure against nonpayment of principal or interest on municipal bonds resulting from the insolvency, negligence or any other act or omission of the trustee or other paying agent for these bonds.

Original Issue Insurance remains in effect as long as the municipal bonds it covers remain outstanding and the insurer remains in business, regardless of whether the Fund ultimately disposes of these municipal bonds. Consequently, Original Issue Insurance may be considered to represent an

16

element of market value with respect to the municipal bonds so insured, but the exact effect, if any, of this insurance on the market value cannot be estimated.

Secondary Market Insurance. Subsequent to the time of original issuance of a municipal bond, the Fund or a third party may, upon the payment of a single premium, purchase insurance on that security. Secondary Market Insurance generally provides the same type of coverage as Original Issue Insurance and, as with Original Issue Insurance, Secondary Market Insurance remains in effect as long as the municipal bonds it covers remain outstanding and the insurer remains in business, regardless of whether the Fund ultimately disposes of these municipal bonds.

One of the purposes of acquiring Secondary Market Insurance with respect to a particular municipal bond would be to enable the Fund to enhance the value of the security. The Fund, for example, might seek to purchase a particular municipal bond and obtain Secondary Market Insurance, for it if, in Nuveen Advisory's opinion, the market value of the security, as insured, less the cost of the Secondary Market Insurance would exceed the current value of the security without insurance. Similarly, if the Fund owns but wishes to sell a municipal bond that is then covered by Portfolio Insurance, the Fund might seek to obtain Secondary Market Insurance for it if, in Nuveen Advisory's opinion, the net proceeds of the Fund's sale of the security, as insured, less the cost of the Secondary Market Insurance would exceed the current value of the security. In determining whether to insure municipal bonds the Fund owns, an insurer will apply its own standards, which correspond generally to the standards it has established for determining the insurability of new issues of municipal bonds. See "--Original Issue Insurance" above.

Portfolio Insurance. Portfolio Insurance guarantees the payment of principal and interest on specified eligible municipal bonds purchased by the Fund. Except as described below, Portfolio Insurance generally provides the same type of coverage as is provided by Original Issue Insurance or Secondary Market Insurance. Municipal bonds insured under a Portfolio Insurance policy would generally not be insured under any other policy. A municipal bond is eligible for coverage under a policy if it meets certain requirements of the insurer. Portfolio Insurance is intended to reduce financial risk, but the cost thereof and compliance with investment restrictions imposed under the policy will reduce the yield to shareholders of the Fund.

If a municipal bond is already covered by Original Issue Insurance or Secondary Market Insurance, then the security is not required to be additionally insured under any Portfolio Insurance that the Fund may purchase. All premiums respecting municipal bonds covered by Original Issue Insurance or Secondary Market Insurance are paid in advance by the issuer or other party obtaining the insurance.

Portfolio Insurance policies are effective only as to municipal bonds owned by and held by the Fund, and do not cover municipal bonds for which the contract for purchase fails. A "when-issued" municipal obligation will be covered under a Portfolio Insurance policy upon the settlement date of the issue of such "when-issued" municipal bond.

In determining whether to insure municipal bonds held by the Fund, an insurer will apply its own standards, which correspond generally to the standards it has established for determining the insurability of new issues of municipal bonds. See "--Original Issue Insurance" above.

Each Portfolio Insurance policy will be noncancellable and will remain in effect so long as the Fund is in existence, the municipal bonds covered by the policy continue to be held by the Fund, and the

17

Fund pays the premiums for the policy. Each insurer will generally reserve the right at any time upon 90 days' written notice to the Fund to refuse to insure any additional bonds purchased by the Fund after the effective date of such notice. The Fund generally will reserve the right to terminate each policy upon seven days' written notice to an insurer if it determines that the cost of such policy is not reasonable in relation to the value of the insurance to the Fund.

Each Portfolio Insurance policy will terminate as to any municipal bond that has been redeemed from or sold by the Fund on the date of redemption or the settlement date of sale, and an insurer will not have any liability thereafter under a policy for any municipal bond, except that if the redemption date or settlement date occurs after a record date and before the related payment date for any municipal bond, the policy will terminate for that municipal bond on the business day immediately following the payment date. Each policy will terminate as to all municipal bonds covered thereby on the date on which the last of the covered municipal bonds mature, are redeemed or are sold by the Fund.

One or more Portfolio Insurance policies may provide the Fund, pursuant to an irrevocable commitment of the insurer, with the option to exercise the right to obtain permanent insurance ("Permanent Insurance") for a municipal bond that is sold by the Fund. The Fund would exercise the right to obtain Permanent Insurance upon payment of a single, predetermined insurance premium payable from the sale proceeds of the municipal bond. The Fund expects to exercise the right to obtain Permanent Insurance for a municipal bond only if, in Nuveen Advisory's opinion, upon the exercise the net proceeds from the sale of the municipal bond, as insured, would exceed the proceeds from the sale of the security without insurance.

The Permanent Insurance premium for each municipal bond is determined based upon the insurability of each security as of the date of purchase and will not be increased or decreased for any change in the security's creditworthiness unless the security is in default as to payment of principal or interest, or both. If such event occurs, the Permanent Insurance premium will be subject to an increase predetermined at the date of the Fund's purchase.

The Fund generally intends to retain any insured bonds covered by Portfolio Insurance that are in default or in significant risk of default and to place a value on the insurance, which ordinarily will be the difference between the market value of the defaulted bond and the market value of similar bonds of minimum investment grade (that is, rated "Baa" or "BBB") that are not in default. In certain circumstances, however, Nuveen Advisory may determine that an alternative value for the insurance, such as the difference between the market value of the defaulted bond and either its par value or the market value of similar bonds that are not in default or in significant risk of default, is more appropriate. Except as described above for bonds covered by Portfolio Insurance that are in default or subject to significant risk of default, the Fund will not place any value on the Portfolio Insurance in valuing the municipal bonds it holds.

Because each Portfolio Insurance policy will terminate for municipal bonds sold by the Fund on the date of sale, in which event the insurer will be liable only for those payments of principal and interest that are then due and owing (unless Permanent Insurance is obtained by the Fund), the provision for this insurance will not enhance the marketability of the Fund's bonds, whether or not the bonds are in default or in significant risk of default. On the other hand, because Original Issue Insurance and Secondary Market Insurance generally will remain in effect as long as the municipal bonds they cover are outstanding, these insurance policies may enhance the marketability of these bonds even when they are in default or in significant risk of default, but the exact effect, if any, on marketability, cannot be

18

estimated. Accordingly, the Fund may determine to retain or, alternatively, to sell municipal bonds covered by Original Issue Insurance or Secondary Market Insurance that are in default or in significant risk of default.

Premiums for a Portfolio Insurance policy are paid monthly, and are adjusted for purchases and sales of municipal bonds covered by the policy during the month. The yield on the Fund is reduced to the extent of the insurance premiums it pays.

When-Issued and Delayed Delivery Transactions

The Fund may buy and sell municipal bonds 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.

Miscellaneous Investments

The Fund, either singly or in conjunction with other funds advised or subadvised by Nuveen Advisory or an affiliate thereof, may invest in taxable fixed-income or equity securities, for the purposes of acquiring control of an issuer whose municipal bonds (a) the Fund already owns and (b) have deteriorated or are expected shortly to deteriorate significantly in credit quality, provided Nuveen Advisory determines that such investment should enable the Fund to better maximize its existing investment in such issuer. Investment in taxable securities would result in a portion of your dividend being subject to regular federal income tax.

Other Investment Companies

The Fund may invest up to 10% of its net assets in securities of other open- or closed-end investment companies that invest primarily in municipal bonds of the types in which the Fund may invest directly. The Fund generally expects to invest in other investment companies 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 bonds 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 the investment company relative to available municipal bond 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 "Risks," 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.

19

MUNIPREFERRED SHARES AND LEVERAGE

Subject to market conditions, approximately one to three months after the completion of the offering of the Common Shares, the Fund intends to offer MuniPreferred Shares representing approximately 35% of the Fund's capital immediately after the issuance of the MuniPreferred Shares. The MuniPreferred Shares will have complete priority upon distribution of assets over the Common Shares. The issuance of MuniPreferred Shares will leverage the Common Shares. Leverage involves special risks. There is no assurance that the Fund's leveraging strategy will be successful. Although the timing and other terms of the offering of the MuniPreferred Shares will be determined by the Fund's Board of Trustees, the Fund expects to invest the proceeds of the MuniPreferred Shares offering in long-term municipal bonds. The MuniPreferred Shares will pay dividends based on shorter-term rates (which would be redetermined periodically by an auction process). So long as the Fund's portfolio is invested in securities that provide a higher rate of return than the dividend rate of the MuniPreferred Shares (after taking expenses into consideration), the leverage will cause you to receive a higher current rate of return than if the Fund were not leveraged.

Changes in the value of the Fund's bond portfolio (including bonds bought with the proceeds of the MuniPreferred Shares offering) will be borne entirely by the Common Shareholders. If there is a net decrease (or increase) in the value of the Fund's investment portfolio, the leverage will decrease (or increase) the net asset value per Common Share to a greater extent than if the Fund were not leveraged. During periods in which the Fund is using leverage, the fees paid to Nuveen Advisory for advisory services will be higher than if the Fund did not use leverage because the fees paid will be calculated on the basis of the Fund's total net assets, including the proceeds from the issuance of MuniPreferred Shares.

For tax purposes, the Fund is currently required to allocate net capital gain and other taxable income, if any, between the Common Shares and MuniPreferred Shares in proportion to total dividends paid to each class for the year in which the net capital gain or other taxable income is realized. If net capital gain or other taxable income is allocated to MuniPreferred Shares (instead of solely tax-exempt income), the Fund will likely have to pay higher total dividends to MuniPreferred Shareholders or make special payments to MuniPreferred Shareholders to compensate them for the increased tax liability. This would reduce the total amount of dividends paid to the Common Shareholders, but would increase the portion of the dividend that is tax-exempt. On an after-tax basis, Common Shareholders may still be better off than if they had been allocated all of the Fund's net capital gain or other taxable income (resulting in a higher amount of total dividends), but received a lower amount of tax-exempt income. If the increase in dividend payments or the special payments to MuniPreferred Shareholders are not entirely offset by a reduction in the tax liability of, and an increase in the tax-exempt dividends received by, the Common Shareholders, the advantage of the Fund's leveraged structure to Common Shareholders will be reduced.

Under the 1940 Act, the Fund is not permitted to issue preferred shares unless immediately after such issuance, the value of the Fund's asset coverage is at least 200% of the liquidation value of the outstanding preferred shares (i.e., such liquidation value may not exceed 50% of the Fund's asset coverage). In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Shares unless, at the time of such declaration, the value of the Fund's asset coverage is at least 200% of such liquidation value. If MuniPreferred Shares are issued, the Fund intends, to the extent possible, to purchase or redeem MuniPreferred Shares from time to time to the extent necessary in order to maintain coverage of any MuniPreferred Shares of at least 200%. If the Fund has MuniPreferred

20

Shares outstanding, two of the Fund's trustees will be elected by the holders of MuniPreferred Shares, voting separately as a class. The remaining trustees of the Fund will be elected by holders of Common Shares and MuniPreferred Shares voting together as a single class. In the event the Fund failed to pay dividends on MuniPreferred Shares for two years, MuniPreferred Shareholders would be entitled to elect a majority of the trustees of the Fund.

The Fund may be subject to certain restrictions imposed by guidelines of one or more rating agencies which may issue ratings for MuniPreferred Shares issued by the Fund. These guidelines may impose asset coverage or portfolio composition requirements that are more stringent than those imposed on the Fund by the 1940 Act. It is not anticipated that these covenants or guidelines will impede Nuveen Advisory from managing the Fund's portfolio in accordance with the Fund's investment objectives and policies.

The Fund may also borrow money for repurchase of its shares or as a temporary measure for extraordinary or emergency purposes, including the payment of dividends and the settlement of securities transactions which otherwise might require untimely dispositions of Fund securities.

Assuming that the MuniPreferred Shares will represent in the aggregate approximately 35% of the Fund's capital and pay dividends at an annual average rate of %, the incremental income generated by the Fund's portfolio (net of estimated expenses) must exceed % in order to cover such dividend payments and other expenses specifically related to the MuniPreferred Shares. Of course, these numbers are merely estimates, used for illustration. Actual MuniPreferred Share dividend rates, interest or payment rates may vary frequently and may be significantly higher or lower than the rate assumed above.

The following table is furnished in response to requirements of the Securities and Exchange Commission. It is designed to illustrate the effect of leverage on Common Share total return, assuming investment portfolio total returns (comprised of income and changes in the value of bonds held in the Fund's portfolio) of -10%, -5%, 0%, 5% and 10%. These assumed investment portfolio returns are hypothetical figures and are not necessarily indicative of the investment portfolio returns expected to be experienced by the Fund. The table further reflects the issuance of MuniPreferred Shares representing 35% of the Fund's total capital, and the Fund's currently projected annual MuniPreferred Share dividend rate of %. See "Risks" and "MuniPreferred Shares and Leverage."

Assumed Portfolio Total Return (10.00)% (5.00)% 0.00 % 5.00% 10.00%
Common Share Total Return.....    (  )%   (  )%  (  )%     %      %

Common Share total return is composed of two elements--the Common Share dividends paid by the Fund (the amount of which is largely determined by the net investment income of the Fund after paying dividends on MuniPreferred Shares) and gains or losses on the value of the securities the Fund owns. As required by Securities and Exchange Commission rules, the table assumes that the Fund is more likely to suffer capital losses than to enjoy capital appreciation. For example, to assume a total return of 0%, the Fund must assume that the tax-exempt interest it receives on its municipal bond investments is entirely offset by losses in the value of those bonds.

Unless and until MuniPreferred Shares are issued, the Common Shares will not be leveraged and this section will not apply.

21

RISKS

The net asset value of the Common Shares will fluctuate with and be affected by, among other things, interest rate risk, credit risk, reinvestment risk and leverage risk, and an investment in Common Shares will be subject to market discount risk, inflation risk and municipal bond market risk, each of which is more fully described below.

Newly Organized. The Fund is a newly organized, diversified, closed-end management investment company and has no operating history.

Market Discount Risk. Shares of closed-end management investment companies frequently trade at a discount from their net asset value.

Interest Rate Risk. Interest rate risk is the risk that bonds (and the Fund's net assets) will decline in value because of changes in interest rates. Generally, municipal bonds will decrease in value when interest rates rise and increase in value when interest rates decline. This means that the net asset value of the Common Shares will fluctuate with interest rate changes and the corresponding changes in the value of the Fund's municipal bond holdings. The value of the longer-term bonds in which the Fund generally invests fluctuates more in response to changes in interest rates than does the value of shorter-term bonds. Conversely, the values of lower-rated and comparable unrated debt securities are less likely than those of investment grade and comparable unrated debt securities to fluctuate inversely with changes in interest rates. Because the Fund will invest primarily in long-term bonds, the Common Share net asset value and market price per share will fluctuate more in response to changes in market interest rates than if the Fund invested primarily in shorter-term bonds. The Fund's use of leverage, as described below, will tend to increase Common Share interest rate risk.

Credit Risk. Credit risk is the risk that one or more municipal bonds in the Fund's portfolio will decline in price, or fail to pay interest or principal when due, because the issuer of the bond experiences a decline in its financial status. In general, lower-rated municipal bonds 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.

Municipal Bond Market Risk. Investing in the municipal bond market involves certain risks. The amount of public information available about the municipal bonds 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 bonds 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 bonds 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 protection under the bankruptcy laws. In the event of bankruptcy of

22

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.

Municipal Bond Insurance. In the event Moody's, S&P or Fitch (or all of them) should downgrade its assessment of the claims-paying ability of a particular insurer, it (or they) could also be expected to downgrade the ratings assigned to municipal bonds insured by such insurer, and municipal bonds insured under Portfolio Insurance issued by such insurer also would be of reduced quality in the portfolio of the Fund. Any such downgrade could have an adverse impact on the net asset value and market price of the Common Shares.

In addition, the Fund may be subject to certain restrictions on investments imposed by guidelines of the insurance companies issuing portfolio insurance. The Fund does not expect these guidelines to prevent Nuveen Advisory from managing the Fund's portfolio in accordance with the Fund's investment objectives and policies.

Reinvestment Risk. Reinvestment risk is the risk that income from the Fund's bond 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.

Leverage Risk. Leverage risk is the risk associated with the issuance of the MuniPreferred Shares to leverage the Common Shares. There can be no assurance that the Fund's leveraging strategy will be successful. Once the MuniPreferred Shares are issued, the net asset value and market value of Common Shares will be more volatile, and the yield to Common Shareholders will tend to fluctuate with changes in the shorter-term dividend rates on the MuniPreferred Shares. Long-term municipal bond rates of return are typically, although not always, higher than shorter-term municipal bond rates of return. If the dividend rate on the MuniPreferred Shares approaches the net rate of return on the Fund's investment portfolio, the benefit of leverage to Common Shareholders would be reduced. If the dividend rate on the MuniPreferred Shares exceeds the net rate of return on the Fund's portfolio, the leverage will result in a lower rate of return to Common Shareholders than if the Fund were not leveraged. Because the long- term bonds included in the Fund's portfolio will typically pay fixed rates of interest while the dividend rate on the MuniPreferred Shares will be adjusted periodically, this could occur even when both long-term and short-term municipal rates rise. In addition, the Fund will pay (and Common Shareholders will bear) any costs and expenses relating to the issuance and ongoing maintenance of the MuniPreferred Shares (for example, distribution related expenses such as the participation fee paid at what it expects will be an annual rate of 0.25% of MuniPreferred Share liquidation preference to broker-dealers participating in MuniPreferred Share auctions). Accordingly, the Fund cannot assure you that the issuance of MuniPreferred Shares will result in a higher yield or return to Common Shareholders.

Similarly, any decline in the net asset value of the Fund's investments will be borne entirely by Common Shareholders. Therefore, if the market value of the Fund's portfolio declines, the leverage will result in a greater decrease in net asset value to Common Shareholders than if the Fund were not leveraged. Such greater net asset value decrease will also tend to cause a greater decline in the market

23

price for the Common Shares. The Fund might be in danger of failing to maintain the required 200% asset coverage or of losing its expected AAA/Aaa ratings on the MuniPreferred Shares or, in an extreme case, the Fund's current investment income might not be sufficient to meet the dividend requirements on the MuniPreferred Shares. In order to counteract such an event, the Fund might need to liquidate investments in order to fund a redemption of some or all of the MuniPreferred Shares. Liquidation at times of low municipal bond prices may result in capital loss and may reduce returns to Common Shareholders.

While the Fund may from time to time consider reducing leverage in response to actual or anticipated changes in interest rates in an effort to mitigate the increased volatility of current income and net asset value associated with leverage, there can be no assurance that the Fund will actually reduce leverage in the future or that any reduction, if undertaken, will benefit the Common Shareholders. Changes in the future direction of interest rates are very difficult to predict accurately. If the Fund were to reduce leverage based on a prediction about future changes to interest rates, and that prediction turned out to be incorrect, the reduction in leverage would likely operate to reduce the income and/or total returns to Common Shareholders relative to the circumstance where the Fund had not reduced leverage. The Fund may decide that this risk outweighs the likelihood of achieving the desired reduction to volatility in income and share price if the prediction were to turn out to be correct, and determine not to reduce leverage as described above.

The Fund may invest in the securities of other investment companies. Such securities may also be leveraged and will therefore be subject to the leverage risks described above. Such additional leverage may in certain market conditions serve to reduce the net asset value of the Fund's Common Shares and the returns to Common Shareholders.

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 Common Shares and distributions can decline. In addition, during any periods of rising inflation, MuniPreferred Share dividend rates would likely increase, which would tend to further reduce returns to Common Shareholders.

Anti-Takeover Provisions. The Fund's Declaration includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or convert the Fund to open-end status. These provisions could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares.

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, if issued, MuniPreferred Shares voting together as a single class, and the approval 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

24

(ii) more than 50% of the shares, whichever is less. Among other restrictions, the Fund may not invest more than 25% of total Fund assets in securities of issuers in any one industry, except that this limitation does not apply to municipal bonds backed by the assets and revenues of governments or political subdivisions of governments.

The Fund may become subject to guidelines which are more limiting than the investment restriction set forth above in order to obtain and maintain ratings from Moody's or S&P on the MuniPreferred Shares that it intends to issue. The Fund does not anticipate that such guidelines would have a material adverse effect on the Fund's Common Shareholders or the Fund's ability to achieve its investment objectives. 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.

The Fund seeks to reduce credit risk by buying bonds that are either covered by insurance or backed by an escrow or trust account, each with the purpose of ensuring timely payment of principal and interest. However, these municipal bonds remain subject to market risk.

Limited Issuance of MuniPreferred Shares

Under the 1940 Act, the Fund could issue MuniPreferred Shares having a total liquidation value (original purchase price of the shares being liquidated plus any accrued and unpaid dividends) of up to one-half of the value of the asset coverage of the Fund. If the total liquidation value of the MuniPreferred Shares was ever more than one-half of the value of the Fund's asset coverage, the Fund would not be able to declare dividends on the Common Shares until the liquidation value, as a percentage of the Fund's assets, was reduced. The Fund intends to issue MuniPreferred Shares representing about 35% of the Fund's total capital immediately after the time of issuance. This higher than required margin of net asset value provides a cushion against later fluctuations in the value of the Fund's portfolio and will subject Common Shareholders to less income and net asset value volatility than if the Fund were more leveraged. The Fund intends to purchase or redeem MuniPreferred Shares, if necessary, to keep the liquidation value of the MuniPreferred Shares below one-half of the value of the Fund's asset coverage.

Management of Investment Portfolio and Capital Structure to Limit Leverage Risk

The Fund may take certain actions if short-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. As explained above under "Risks--Leverage Risk," 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.

25

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.

Currently, 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 bond. 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 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. Successful implementation of most hedging strategies would generate taxable income, and the Fund has no present intention to use these strategies.

MANAGEMENT OF THE FUND

Investment Management Agreement

Pursuant to an investment management agreement between Nuveen Advisory and the Fund, the Fund has agreed to pay for the services and facilities provided by Nuveen Advisory an annual management fee, payable on a monthly basis, according to the following schedule:

                                                            Management
Average Daily Managed Assets                                   Fee

$500 million to $1 billion.................................   .6125%
$1 billion to $2 billion...................................   .6000%
$2 billion and over........................................   .5750%

If the Fund utilizes leverage through the issuance of MuniPreferred Shares in an amount equal to 35% of the Fund's total assets (including the amount obtained from leverage), the management fee calculated as a percentage of net assets attributable to Common Shares would be as follows:

                                                            Management
Net Assets Attributable to Common Shares                       Fee

$500 million to $1 billion.................................    .9423%
$1 billion to $2 billion...................................    .9231%
$2 billion and over........................................    .8846%

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 any MuniPreferred Shares, expenses of preparing, printing and distributing shareholder reports, notices, proxy statements and reports to governmental agencies, and taxes, if any.

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:

27

Nuveen Advisory has not agreed to reimburse the Fund for any portion of its fees and expenses beyond , 2010.

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.

DISTRIBUTIONS

Commencing with the first dividend, the Fund intends to make regular monthly cash distributions to Common Shareholders at a level rate (stated in terms of a fixed cents per Common Share dividend rate) that reflects the past and projected performance of the Fund. Distributions can only be made from net investment income after paying any accrued dividends to MuniPreferred Shareholders. The Fund's ability to maintain a level dividend rate will depend on a number of factors, including dividends payable on the MuniPreferred Shares. The net income of the Fund consists of all interest income accrued on portfolio assets less all expenses of the Fund. Expenses of the Fund are accrued each day. Over time, all the net investment income of the Fund will be distributed. At least annually, the Fund also intends to distribute net capital gain and ordinary taxable income, if any, after paying any accrued dividends or making any liquidation payments to MuniPreferred Shareholders. Initial distributions to Common Shareholders are expected to be declared approximately 45 days, and paid approximately 60 to 90 days, from the completion of this offering, depending on market conditions. Although it does not now intend to do so, the Board of Trustees may change the Fund's dividend policy and the amount or timing of the distributions, based on a number of factors, including the amount of the Fund's undistributed net investment income and historical and projected investment income and the amount of the expenses and dividend rates on the outstanding MuniPreferred Shares.

To permit the Fund to maintain a more stable monthly distribution, the Fund will initially distribute less than the entire amount of net investment income earned in a particular period. The undistributed net investment income would be available to supplement future distributions. As a result, the distributions paid by the Fund for any particular monthly period may be more or less than the amount of net investment income actually earned by the Fund during the period. Undistributed net investment income will be added to the Fund's net asset value and, correspondingly, distributions from undistributed net investment income will be deducted from the Fund's net asset value.

28

DIVIDEND REINVESTMENT PLAN

You may elect to have all dividends, including any capital gain dividends, on your Common Shares automatically reinvested by the Plan Agent in additional Common Shares under the Dividend Reinvestment Plan (the "Plan"). You may elect to participate in the Plan by completing the Dividend Reinvestment Plan Application Form. If you do not participate, you will receive all distributions in cash paid by check mailed directly to you by State Street Bank and Trust Company as dividend paying agent.

If you decide to participate in the Plan, the number of Common Shares you will receive will be determined as follows:

(1) If Common Shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the then current market price; or

(2) If Common Shares are trading below net asset value at the time of valuation, the Plan Agent will receive the dividend or distribution in cash and will purchase Common Shares in the open market, on the or elsewhere, for the participants' accounts. It is possible that the market price for the Common Shares may increase before the Plan Agent has completed its purchases. Therefore, the average purchase price per share paid by the Plan Agent may exceed the market price at the time of valuation, resulting in the purchase of fewer shares than if the dividend or distribution had been paid in Common Shares issued by the Fund. The Plan Agent will use all dividends and distributions received in cash to purchase Common Shares in the open market within 30 days of the valuation date. Interest will not be paid on any uninvested cash payments.

You may withdraw from the Plan at any time by giving written notice to the Plan Agent. If you withdraw or the Plan is terminated, you will receive a certificate for each whole share in your account under the Plan and you will receive a cash payment for any fraction of a share in your account. If you wish, the Plan Agent will sell your shares and send you the proceeds, minus brokerage commissions and a $2.50 service fee.

The Plan Agent maintains all shareholders' accounts in the Plan and gives written confirmation of all transactions in the accounts, including information you may need for tax records. Common Shares in your account will be held by the Plan Agent in non-certificated form. Any proxy you receive will include all Common Shares you have received under the Plan.

There is no brokerage charge for reinvestment of your dividends or distributions in Common Shares. However, all participants will pay a pro rata share of brokerage commissions incurred by the Plan Agent when it makes open market purchases.

Automatically reinvesting dividends and distributions does not mean that you do not have to pay income taxes due upon receiving dividends and distributions.

The Fund reserves the right to amend or terminate the Plan if in the judgment of the Board of Trustees the change is warranted. There is no direct service charge to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable by the participants. Additional information about the Plan may be obtained from State Street Bank and Trust Company, Attn: Equiserve Nuveen Investments, P.O. Box 43071, Providence, Rhode Island 02940-3071, (800) 257-8787.

DESCRIPTION OF SHARES

Common Shares

The Declaration authorizes the issuance of an unlimited number of Common Shares. The Common Shares being offered have a par value of $0.01 per share and, subject to the rights of holders of MuniPreferred Shares, if issued, have equal rights to the payment of dividends and the distribution of assets upon liquidation. The Common Shares being offered will, when issued, be fully paid and, subject to matters discussed in "Certain Provisions in the Declaration of Trust," non-assessable, and will have no pre-emptive or conversion rights or rights to cumulative voting. Whenever MuniPreferred Shares are outstanding, Common Shareholders 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. See "--MuniPreferred Shares" below.

The Common Shares have been approved for listing on the , subject to notice of issuance. The Fund intends to hold annual meetings of shareholders so long as the Common Shares are listed on a national securities exchange and such meetings are required as a condition to such listing.

The Fund's net asset value per share generally increases when interest rates decline, and decreases when interest rates rise, and these changes are likely to be greater because the Fund intends to have a leveraged capital structure. Net asset value will be reduced immediately following the offering by the amount of the sales load and offering expenses paid by the Fund. Nuveen has agreed to pay (i) all organizational expenses and (ii) offering costs (other than sales load) that exceed $0.03 per Common Share. See "Use of Proceeds."

Unlike open-end funds, closed-end funds like the Fund do not continuously offer shares and do not provide daily redemptions. Rather, if a shareholder determines to buy additional Common Shares or sell shares already held, the shareholder may conveniently do so by trading on the exchange through a broker or otherwise. Shares of closed-end investment companies may frequently trade on an exchange at prices lower than net asset value. Shares of closed-end investment companies like the Fund that invest predominately in investment grade municipal bonds have during some periods traded at prices higher than net asset value and have during other periods traded at prices lower than net asset value. Because the market value of the Common Shares may be influenced by such factors as dividend levels (which are in turn affected by expenses), call protection, dividend stability, portfolio credit quality, net asset value, relative demand for and supply of such shares in the market, general market and economic conditions, and other factors beyond the control of the Fund, the Fund cannot assure you that Common Shares will trade at a price equal to or higher than net asset value in the future. The Common Shares are designed primarily for long-term investors, and investors in the Common Shares should not view the Fund as a vehicle for trading purposes. See "MuniPreferred Shares and Leverage" and the Statement of Additional Information under "Repurchase of Fund Shares; Conversion to Open-End Fund."

MuniPreferred Shares

The Declaration authorizes the issuance of an unlimited number of MuniPreferred Shares in one or more classes or series, with rights as determined by the Board of Trustees, by action of the Board of Trustees without the approval of the Common Shareholders.

30

The Fund's Board of Trustees has authorized an offering of MuniPreferred Shares (representing approximately 35% of the Fund's capital immediately after the time the MuniPreferred Shares are issued) approximately one to three months after completion of the offering of Common Shares. The Board has determined that the MuniPreferred Shares, at least initially, would pay cumulative dividends at rates determined weekly by providing for the periodic redetermination of the dividend rate through an auction or remarketing procedure. The Board of Trustees has indicated that the preference on distribution, liquidation preference, voting rights and redemption provisions of the MuniPreferred Shares will be as stated below.

Limited Issuance of MuniPreferred Shares. Under the 1940 Act, the Fund could issue MuniPreferred Shares with an aggregate liquidation value of up to one-half of the value of the Fund's total net assets, measured immediately after issuance of the MuniPreferred Shares. "Liquidation value" means the original purchase price of the shares being liquidated plus any accrued and unpaid dividends. In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Shares unless the liquidation value of the MuniPreferred Shares is less than one-half of the value of the Fund's total net assets (determined after deducting the amount of such dividend or distribution) immediately after the distribution. If the Fund sells all the Common Shares and MuniPreferred Shares discussed in this Prospectus, the liquidation value of the MuniPreferred Shares is expected to be approximately 35% of the value of the Fund's total net assets. The Fund intends to purchase or redeem MuniPreferred Shares, if necessary, to keep that fraction below one-half.

Distribution Preference. The MuniPreferred Shares have complete priority over the Common Shares as to distribution of assets.

Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Fund, holders of MuniPreferred Shares will be entitled to receive a preferential liquidating distribution (expected to equal the original purchase price per share plus accumulated and unpaid dividends thereon, whether or not earned or declared) before any distribution of assets is made to Common Shareholders.

Voting Rights. MuniPreferred Shares are required to be voting shares and to have equal voting rights with Common Shares. Except as otherwise indicated in this Prospectus or the Statement of Additional Information and except as otherwise required by applicable law, holders of MuniPreferred Shares will vote together with Common Shareholders as a single class.

Holders of MuniPreferred Shares, voting as a separate class, will be entitled to elect two of the Fund's trustees (following the establishment of the Fund by an initial trustee, the Declaration provides for a total of no less than two and no more than twelve trustees). The remaining trustees will be elected by Common Shareholders and holders of MuniPreferred Shares, voting together as a single class. In the unlikely event that two full years of accrued dividends are unpaid on the MuniPreferred Shares, the holders of all outstanding MuniPreferred Shares, voting as a separate class, will be entitled to elect a majority of the Fund's trustees until all dividends in arrears have been paid or declared and set apart for payment. Under the 1940 Act, in order for the Fund to take certain actions or enter into certain transactions (i.e., convert to an open-end investment company or effect a reorganization adversely affecting the MuniPreferred Shares), a separate class vote of holders of MuniPreferred Shares will be required, in addition to the single class vote of the holders of MuniPreferred Shares and Common Shares. See the Statement of Additional Information under "Description of Shares--MuniPreferred Shares--Voting Rights."

31

Redemption, Purchase and Sale of MuniPreferred Shares. The terms of the MuniPreferred Shares provide that they may be redeemed by the issuer at certain times, in whole or in part, at the original purchase price per share plus accumulated dividends. Any redemption or purchase of MuniPreferred Shares by the Fund will reduce the leverage applicable to Common Shares, while any issuance of shares by the Fund will increase such leverage. See "MuniPreferred Shares and Leverage."

The discussion above describes the Board of Trustees' present intention with respect to an offering of MuniPreferred Shares. The terms of the MuniPreferred Shares may be the same as, or different from, the terms described above, subject to applicable law and the Fund's Declaration.

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 or recapitalization 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. 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. 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

32

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. 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."

The provisions of the Declaration described above could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over the then current market price of the Common Shares by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. The overall effect of these provisions is to render more difficult the accomplishment of a merger or the assumption of control by a third party. They provide, however, the advantage of potentially requiring persons seeking control of the Fund to negotiate with its management regarding the price to be paid and facilitating the continuity of the Fund's investment objectives and policies. The Board of Trustees of the Fund has considered the foregoing anti-takeover provisions and concluded that they are in the best interests of the Fund and its Common Shareholders.

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.

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 . 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

33

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.

TAX MATTERS

Federal Income Tax Matters

The following discussion of federal income tax matters is based on the advice of Bell, Boyd & Lloyd LLC, special counsel to the Fund.

The discussions below and in the Statement of Additional Information provide general tax information related to an investment in the Common Shares. Because tax laws are complex and often change, you should consult your tax advisor about the tax consequences of an investment in the Fund.

The Fund intends to elect to be treated and to qualify 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 bonds 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 bonds whose income is otherwise exempt from regular federal income tax, and the alternative minimum tax applicable to individuals. Thus, substantially all of the Fund's dividends to you will qualify as "exempt-interest dividends." A shareholder treats an exempt-interest dividend as interest on state and local bonds exempt from federal income tax. Different federal alternative minimum tax rules apply to individuals and to corporations.

Although the Fund does not seek to realize taxable income or capital gains, the Fund may realize and distribute taxable income or capital gains from time to time as a result of the Fund's normal investment activities. The Fund will distribute at least annually any ordinary taxable income or net capital gain. Distributions of net short-term capital gain are taxable as ordinary income. Distributions of net capital gain (the excess of net long-term capital gain over net short-term capital loss) are taxable as long-term capital gains regardless of how long you have owned your investment. The Fund will allocate

34

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. 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 allowed to corporations.

Each year, you will receive a year-end statement that describes the tax status of dividends paid to you during the preceding year, including the source of investment income by state and the portion of income that is subject to the federal alternative minimum tax. You will receive this statement from the firm where you purchased your Common Shares if you hold your investment in street name; the Fund will send you this statement if you hold your shares in registered form.

The tax status of your dividends is not affected by whether you reinvest your dividends or receive them in cash.

In order to avoid corporate taxation of its earnings and to pay tax-free dividends, the Fund must meet certain Internal Revenue Service ("I.R.S.") requirements that govern the Fund's sources of income, diversification of assets and distribution of earnings to shareholders. The Fund intends to meet these requirements. If the Fund failed to do so, the Fund would be required to pay corporate taxes on its earnings and all your distributions would be taxable as ordinary income to the extent of the Fund's earnings and profits. In particular, in order for the Fund to pay exempt-interest dividends, at least 50% of the value of the Fund's total assets must consist of tax-exempt obligations at the close of each quarter of its taxable year. The Fund intends to meet this requirement. If the Fund failed to do so, it would not be able to pay exempt-interest dividends and your distributions attributable to interest received by the Fund from any source would be taxable as ordinary income.

The sale or other disposition of Common Shares will result in capital gain or loss to you if you hold such Common 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 eligible for reduced rates of taxation.

The Fund may be required to withhold a percentage of certain of your dividends if you have not provided the Fund with your correct taxpayer identification number (normally your Social Security number) and certain certifications, or if you are otherwise subject to backup withholding. The backup withholding percentage will be 30% in 2002 and 2003, 29% in 2004 and 2005, and 28% thereafter until 2011, when the percentage will revert to 31% unless amended by Congress. If you receive Social Security benefits, you should be aware that exempt-interest dividends are taken into account in calculating the amount of these benefits that may be subject to federal income tax. If you borrow money to buy Fund shares, you may not deduct the interest on that loan. Under I.R.S. rules, Fund shares may be treated as having been bought with borrowed money even if the purchase of the Fund shares cannot be traced directly to borrowed money.

OTHER MATTERS

A lawsuit was brought in June 1996 (Green et al. v. Nuveen Advisory Corp., et al.) by certain individual common shareholders of six leveraged closed-end funds sponsored by Nuveen in the federal district court for the Seventh Circuit Court of Appeals. The suit was originally brought against Nuveen,

35

Nuveen Advisory, six Nuveen investment companies (the "leveraged closed-end funds") managed by Nuveen Advisory and two of the leveraged closed-end funds' former directors seeking unspecified damages, an injunction and other relief. The suit also sought certification of a defendant class consisting of all Nuveen-managed leveraged funds.

The plaintiffs alleged that the leveraged closed-end funds engaged in certain practices that violated various provisions of the 1940 Act and common law. The plaintiffs also alleged, among other things, breaches of fiduciary duty by the funds' directors and Nuveen Advisory and various misrepresentations and omissions in prospectuses and shareholder reports relating to the use of leverage through the issuance and periodic auctioning of preferred stock and the basis of the calculation and payment of management fees to Nuveen Advisory and Nuveen. Plaintiffs also filed a motion to certify defendant and plaintiff classes.

The defendants filed motions to dismiss the entire lawsuit asserting that the claims are without merit and to oppose certification of any classes. On March 30, 1999, the court entered a memorandum opinion and order (1) granting the defendants' motion to dismiss all of plaintiffs' counts against the defendants other than Nuveen Advisory, (2) granting Nuveen Advisory's motion to dismiss all of plaintiffs' counts against it other than breach of fiduciary duty under Section 36(b) of the 1940 Act, and (3) denying the plaintiffs' motion to certify a plaintiff class and a defendant class. No appeal was made by plaintiffs of this decision, and the remaining Section 36(b) count against Nuveen Advisory is discussed below.

As to alleged damages, plaintiffs have claimed as damages the portion of all advisory compensation received by Nuveen Advisory from the funds during the period from June 21, 1995 to the present that is equal to the proportion of each of such fund's preferred stock to its total assets. The preferred stock constitutes approximately one third of the funds' assets so the amount claimed would equal approximately one third of management fees received by Nuveen Advisory for managing the funds during this period. Nuveen Advisory believes that it has no liability and the plaintiffs have suffered no damages and filed a motion for summary judgment as to both liability and damages.

Plaintiffs filed a motion for partial summary judgment as to liability only. In a memorandum opinion and order dated September 6, 2001, the federal district court granted Nuveen Advisory's motion for summary judgment and denied plaintiffs' motion for partial summary judgment, thereby terminating the litigation before the court. Plaintiffs appealed this decision on October 8, 2001. In an opinion dated July 8, 2002, the Seventh Circuit Court of Appeals affirmed the opinion of the district court dismissing the plaintiffs' lawsuit. Any petition for a writ of certiorari to the United States Supreme Court seeking to appeal the Seventh Circuit opinion would need to be filed within ninety days of the Seventh Circuit's July 8, 2002 opinion.

UNDERWRITING

Subject to the terms and conditions stated in the underwriting agreement dated the date hereof, each Underwriter named below has severally agreed to purchase, and the Fund has agreed to sell to such Underwriter, the number of Common Shares set forth opposite the name of such Underwriter.

                                                                       Number of
Underwriters                                                            Shares
------------                                                           ---------
Nuveen Investments....................................................

                                                                        =======

The underwriting agreement provides that the obligations of the several Underwriters to purchase the Common Shares included in this offering are subject to approval of certain legal matters by counsel and to certain other conditions. The Underwriters are obligated to purchase all the Common Shares (other than those covered by the over-allotment option described below) if they purchase any of the Common Shares. The representatives described below have advised the Fund that the Underwriters do not intend to confirm any sales to any accounts over which they exercise discretionary authority.

The Underwriters, for whom Nuveen Investments, are acting as representatives, propose to offer some of the Common Shares directly to the public at the public offering price set forth on the cover page of this Prospectus and some of the Common Shares to certain dealers at the public offering price less a concession not in excess of $0.45 per Common Share. The sales load the Fund will pay of $0.675 per share is equal to 4.5% of the initial offering price. The Underwriters may allow, and such dealers may reallow, a concession not in excess of $0.10 per Common Share on sales to certain other dealers. Certain dealers acting in the capacity of sub-underwriters may receive additional compensation for acting in such a capacity. If all of the Common Shares are not sold at the initial offering price, the representatives may change the public offering price and other selling terms. Investors must pay for any Common Shares purchased on or before , 2002. In connection with this offering, Nuveen may perform clearing services without charge for brokers and dealers for whom it regularly provides clearing services that are participating in the offering as members of the selling group.

The Fund has granted to the Underwriters an option, exercisable for 45 days from the date of this Prospectus, to purchase up to additional Common Shares at the public offering price less the sales load. The Underwriters may exercise such option solely for the purpose of covering over-allotments, if any, in connection with this offering. To the extent such option is exercised, each

37

Underwriter will be obligated, subject to certain conditions, to purchase a number of additional Common Shares approximately proportionate to such Underwriter's initial purchase commitment.

The Fund and Nuveen Advisory have agreed that, for a period of 180 days from the date of this Prospectus, they will not, without the prior written consent of , on behalf of the Underwriters, dispose of or hedge any Common Shares or any securities convertible into or exchangeable for Common Shares. in its sole discretion may release any of the securities subject to these agreements at any time without notice.

Prior to the offering, there has been no public market for the Common Shares. Consequently, the initial public offering price for the Common Shares was determined by negotiation among the Fund, Nuveen Advisory and the representatives. There can be no assurance, however, that the price at which the Common Shares will sell in the public market after this offering will not be lower than the price at which they are sold by the Underwriters or that an active trading market in the Common Shares will develop and continue after this offering. The Common Shares have been approved for listing on the , subject to official notice of issuance.

The Fund and Nuveen Advisory have each agreed to indemnify the several Underwriters or contribute to losses arising out of certain liabilities, including liabilities under the Securities Act of 1933, as amended.

Nuveen has agreed to pay (i) all organizational expenses and (ii) offering costs (other than sales load) that exceed $0.03 per share.

In addition, the Fund has agreed to reimburse the Underwriters for certain expenses incurred by the Underwriters in the offering.

Certain Underwriters participating in the Common Share offering may be invited, some period of time after completion of this offering, to participate in the offering of the MuniPreferred Shares and will receive compensation for their participation in that MuniPreferred Share offering. The number of Common Shares purchased by each Underwriter in this offering may be a factor in determining (i) whether that Underwriter is selected to participate in the offering of the MuniPreferred Shares, (ii) the number of MuniPreferred Shares allocated to that Underwriter in that offering, and (iii) the amount of certain additional MuniPreferred Share underwriting compensation available to that Underwriter. The offering costs associated with the issuance of MuniPreferred Shares are currently estimated to be approximately % of the total amount of the MuniPreferred Share offering. These costs will effectively be borne by the Common Shareholders.

In connection with the requirements for listing the Fund's Common Shares on the , the Underwriters have undertaken to sell lots of 100 or more Common Shares to a minimum of beneficial owners in the United States. The minimum investment requirement is 100 Common Shares.

Certain Underwriters may make a market in the Common Shares after trading in the Common Shares has commenced on the . No Underwriter is, however, obligated to

38

conduct market-making activities and any such activities may be discontinued at any time without notice, at the sole discretion of the Underwriter. No assurance can be given as to the liquidity of, or the trading market for, the Common Shares as a result of any market-making activities undertaken by any Underwriter. This Prospectus is to be used by any Underwriter in connection with the offering and, during the period in which a prospectus must be delivered, with offers and sales of the Common Shares in market-making transactions in the over-the-counter market at negotiated prices related to prevailing market prices at the time of the sale.

The Underwriters have advised the Fund that, pursuant to Regulation M under the Securities Exchange Act of 1934, as amended, certain persons participating in the offering may engage in transactions, including stabilizing bids, covering transactions or the imposition of penalty bids, which may have the effect of stabilizing or maintaining the market price of the Common Shares on the at a level above that which might otherwise prevail in the open market. A "stabilizing bid" is a bid for or purchase of the Common Shares on behalf of an Underwriter for the purpose of fixing or maintaining the price of the Common Shares. A "covering transaction" is a bid for or purchase of the Common Shares on behalf of an Underwriter to reduce a short position incurred by the Underwriters in connection with the offering. A "penalty bid" is a contractual arrangement whereby if, during a specified period after the issuance of the Common Shares, the Underwriters purchase Common Shares in the open market for the account of the underwriting syndicate and the Common Shares purchased can be traced to a particular Underwriter or member of the selling group, the underwriting syndicate may require the Underwriter or selling group member in question to purchase the Common Shares in question at the cost price to the syndicate or may recover from (or decline to pay to) the Underwriter or selling group member in question any or all compensation (including, with respect to a representative, the applicable syndicate management fee) applicable to the Common Shares in question. As a result, an Underwriter or selling group member and, in turn, brokers may lose the fees that they otherwise would have earned from a sale of the Common Shares if their customer resells the Common Shares while the penalty bid is in effect. The Underwriters are not required to engage in any of these activities, and any such activities, if commenced, may be discontinued at any time.

The underwriting agreement provides that it may be terminated in the absolute discretion of the representatives without liability on the part of the Underwriters to the Fund or Nuveen Advisory if, prior to the delivery of and payment for the Common Shares, (i) trading in the Fund's Common Shares shall have been suspended by the Securities and Exchange Commission or the or trading in securities generally on the New York Stock Exchange or the American Stock Exchange shall have been suspended or limited or minimum prices for trading in securities generally shall have been established on either of such Exchanges, (ii) a commercial banking moratorium shall have been declared by either 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 in the United States is such as to make it, in the sole judgment of the representatives, impracticable or inadvisable to proceed with the offering or delivery of the Common Shares as contemplated by the Prospectus (exclusive of any supplement thereto).

The Fund anticipates that from time to time the representatives of the Underwriters and certain other Underwriters may act as brokers or dealers in connection with the execution of 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.

39

Prior to the public offering of Common Shares, Nuveen Advisory purchased Common Shares from the Fund in an amount satisfying the net worth requirements of Section 14(a) of the 1940 Act. As of the date of this Prospectus, Nuveen Advisory owned 100% of the Fund's outstanding Common Shares. Nuveen Advisory may be deemed to control the Fund until such time as it owns less than 25% of the outstanding Common Shares which is expected to occur as of the completion of the offering of Common Shares.

Nuveen, 333 West Wacker Drive, Chicago, Illinois, 60606, one of the representatives of the Underwriters, is the parent company of Nuveen Advisory.

USE OF PROCEEDS

The net proceeds of the offering of Common Shares of the Fund will be approximately: $__________ ($__________ if the Underwriters exercise the over-allotment option in full) after payment of organization and offering costs.

3

For the Fund, Nuveen Advisory has agreed to pay (i) all organizational expenses and (ii) offering costs (other than sales load) that exceed $0.03 per Common Share.

Pending investment in municipal bonds that meet the Fund's investment objectives and policies, the net proceeds of the offering will be invested in high quality, short-term tax-exempt money market securities or in high quality municipal bonds with relatively low volatility (such as pre-refunded and intermediate-term bonds), to the extent such securities are available. If necessary to invest fully the net proceeds of the offering immediately, the Fund may also purchase, as temporary investments, short-term taxable investments of the type described under "Investment Policies and Techniques--Investment in Municipal Bonds--Portfolio Investments," the income on which is subject to regular federal income tax and securities of other open or closed-end investment companies that invest primarily in municipal bonds of the type in which the Fund may invest directly.

4

INVESTMENT OBJECTIVES

The Fund's investment objectives are to provide current income exempt from regular federal income tax, and the alternative minimum tax applicable to individuals, and to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal bonds that the Fund's investment adviser believes are underrated or undervalued or that represent municipal market sectors that are undervalued.

5

The Fund's investment in underrated or undervalued municipal bonds will be based on Nuveen Advisory's belief that their yield is higher than that available on bonds bearing equivalent levels of interest rate risk, credit risk and other forms of risk, and that their prices will ultimately rise (relative to the market) to reflect their true value. The Fund attempts to increase its portfolio value relative to the municipal bond market by prudent selection of municipal bonds regardless of the direction the market may move. Any capital appreciation realized by the Fund will

6

generally result in the distribution of taxable capital gains to holders of Common Shares. The Fund's investment objectives are fundamental policies of the Fund.

Under normal circumstances, the Fund will invest at least 80% of its net assets in a portfolio of municipal bonds that:

. are exempt from regular federal income tax;

. do not pay interest subject to the federal alternative minimum tax applicable to individuals; and

. are covered by insurance guaranteeing the timely payment of principal and interest thereon.

This insurance does not protect the market value of portfolio holdings or the net asset value of the Fund.

The Fund will not invest in bonds that pay interest subject to the federal alternative minimum tax applicable to individuals ("AMT Bonds"). It is a fundamental policy of the Fund that its investments in municipal bonds whose interest is not taxable under regular federal income tax, and the alternative minimum income tax applicable to individuals will, under normal circumstances, comprise at least 80% of the Fund's Managed Assets. The Fund will notify shareholders at least 60 days prior to any change in its policy to invest 80% of its Managed Assets in bonds that are covered by insurance guaranteeing the timely payment of principal and interest thereon.

The Fund may at all times invest up to 20% of its net assets in (i) uninsured municipal bonds that are backed by an escrow or trust account containing sufficient U.S. Government or U.S. Government agency securities to ensure timely payment of principal and interest, or (ii) other municipal bonds that at the time of investment are investment grade quality. Investment grade quality bonds are bonds rated by all NRSROs that rate the bond within the four highest grades (Baa or BBB or better by Moody's, S&P or Fitch), or bonds that are unrated but judged to be of comparable quality by Nuveen Advisory.

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 both regular federal income tax, and the alternative minimum income tax applicable to individuals;

(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 from banks for temporary or emergency purposes or for repurchase of its shares, and then only in an amount not exceeding one-third of the value of the Fund's total assets (including the amount borrowed) less the Fund's liabilities (other than borrowings);

(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 bonds other than those municipal bonds backed only by the assets and revenues of non-governmental users;

7

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

(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, derivative instruments or from investing in securities or other instruments backed by physical commodities);

(8) Make loans, other than by entering into repurchase agreements and through the purchase of municipal bonds or short-term investments in accordance with its investment objectives, policies and limitations; and

(9) Invest more than 5% of its total assets in securities of any one issuer, except that this limitation shall not apply to bonds issued by the United States Government, its agencies and instrumentalities or to the investment of 25% of its total assets.

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 bond 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 bond 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 bonds 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 "Risks", 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.

(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 that the Fund, either singly or in conjunction with other funds advised or subadvised by Nuveen Advisory or an affiliate thereof, may invest in taxable fixed-income or equity securities, for the purpose of acquiring control of an issuer whose municipal bonds (a) the Fund already owns and (b) have deteriorated or are expected shortly to deteriorate significantly in credit quality, provided Nuveen Advisory determines that such investment should enable the Fund to better maximize the value of its existing investment in such issuer.

(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 a leveraged investment in an underlying municipal bond).

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 intends to apply for ratings for its preferred shares (called "MuniPreferred Shares" herein) from Moody's and/or S&P. In order to obtain and maintain the required ratings, the Fund may be required to comply with investment quality, diversification and other guidelines established by Moody's or S&P. Such guidelines will likely be more restrictive than the restrictions set forth above. The Fund does not anticipate that such guidelines would have a material

9

adverse effect on its Common Shareholders or its ability to achieve its investment objectives. The Fund presently anticipates that any MuniPreferred Shares that it intends to issue would be initially given the highest ratings by Moody's ("Aaa") or by S&P ("AAA"), but no assurance can be given that such ratings will be obtained. No minimum rating is required for the issuance of MuniPreferred Shares by the Fund. 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 in Municipal Bonds

Portfolio Investments

Under normal circumstances, the Fund will invest at least 80% of its Managed Assets in a portfolio of municipal bonds that (i) are exempt from regular federal income tax; (ii) do not pay interest subject to the federal alternative income tax applicable to individuals and (iii) are covered by insurance guaranteeing the timely payment of principal and interest thereon. This insurance does not protect the market value of portfolio holdings or the net asset value of the Fund.

The Fund will not invest in AMT Bonds.

The Fund may at all times invest up to 20% of its net assets in (i) uninsured municipal bonds that are backed by an escrow or trust account containing sufficient U.S. Government or U.S. Government agency securities to ensure timely payment of principal and interest, or (ii) other municipal bonds that at the time of investment are investment grade quality. Investment grade quality bonds are bonds rated by all NRSROs that rate the bond within the four highest grades (Baa or BBB or better by Moody's, S&P or Fitch), or bonds that are unrated but judged to be of comparable quality by Nuveen Advisory.

Under normal circumstances, and except for the temporary investments described below, the Fund expects to be fully invested (at least 95% of its assets) in such tax-exempt municipal bonds described above.

10

Municipal bonds rated Baa or BBB are considered "investment grade" securities; municipal bonds rated Baa are considered medium grade obligations which lack outstanding investment characteristics and have speculative characteristics, while municipal bonds rated BBB are regarded as having adequate capacity to pay principal and interest. Municipal bonds rated 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.

A general description of Moody's, S&P's and Fitch's ratings of municipal bonds is set forth in Appendix A hereto. The ratings of Moody's, S&P and Fitch represent their opinions as to the quality of the municipal bonds they rate. It should be emphasized, however, that ratings are general and are not absolute standards of quality. Consequently, municipal bonds 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.

Each insured municipal bond that the Fund holds will either be (1) covered by an insurance policy applicable to a specific security and obtained by the issuer of the security or a third party at the time of original issuance ("Original Issue Insurance"), (2) covered by an insurance policy applicable to a specific security and obtained by the Fund and/or a third party subsequent to the time of original issuance ("Secondary Market Insurance"), or (3) covered by a master municipal insurance policy purchased by the Fund ("Portfolio Insurance"). The Fund, as a non-fundamental policy that can be changed by the Board of Trustees, will only buy Portfolio Insurance from insurers whose claims-paying ability Moody's rates "Aaa" or S&P or Fitch rates "AAA."

Information about the various municipal bond insurers with whom the Fund intends to maintain specific insurance policies for particular municipal bonds or policies of Portfolio Insurance is set forth in Appendix C hereto.

The Fund may at all times invest up to 20% of its net assets in uninsured municipal bonds that are entitled to the benefit of an escrow or trust account that contains securities issued or guaranteed by the U.S. Government or U.S. Government agencies, backed by the full faith and credit of the United States, and sufficient in amount to ensure the payment of interest and principal on the original interest payment and maturity dates ("collateralized obligations"). These collateralized obligations generally will not be insured and will include, but are not limited to municipal bonds that have been (1) advance refunded where the proceeds of the refunding have been used to buy U.S. Government or U.S. Government agency securities that are placed in escrow and whose interest or maturing principal payments, or both, are sufficient to cover the remaining scheduled debt service on that municipal bond; or (2) issued under state or local housing finance programs that use the issuance proceeds to fund mortgages that are then exchanged for U.S. Government or U.S. Government agency securities and deposited with a trustee as security for those municipal bonds. These collateralized obligations are normally regarded as having the credit characteristics of the underlying U.S. Government or U.S. Government agency securities.

11

The Fund will primarily invest in municipal bonds with long-term maturities in order to maintain a weighted average maturity of 15-30 years, but the average weighted maturity of obligations held by the Fund may be shortened, depending on market conditions. As a result, the Fund's portfolio at any given time may include both long-term and intermediate-term municipal bonds. 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 bond market adversely affect the price at which long-term or intermediate-term municipal bonds 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 net assets in securities of other open or closed-end investment companies that invest primarily in municipal bonds 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 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 A 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

12

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.

Nuveen Advisory seeks to enhance portfolio value relative to the municipal bond market by investing in tax-exempt municipal bonds that it believes are underrated or undervalued or that represent municipal market sectors that are undervalued. Underrated municipal bonds are those whose ratings do not, in Nuveen Advisory's opinion, reflect their true creditworthiness. Undervalued municipal bonds are bonds that, in Nuveen Advisory's opinion, are worth more than the value assigned to them in the marketplace. Nuveen Advisory may at times believe that bonds associated with a particular municipal market sector (for example, electric utilities), or issued by a particular municipal issuer, are undervalued. Nuveen Advisory may purchase such a bond for the Fund's portfolio because it represents a market sector or issuer that Nuveen Advisory considers undervalued, even if the value of the particular bond is consistent with the value of similar bonds. Municipal bonds of particular types or purposes (e.g., hospital bonds, industrial revenue bonds or bonds issued by a particular municipal issuer) may be undervalued because there is a temporary excess of supply in that market sector, or because of a general decline in the market price of municipal bonds of the market sector for reasons that do not apply to the particular municipal bonds that are considered undervalued. The Fund's investment in underrated or undervalued municipal bonds will be based on Nuveen Advisory's belief that their yield is higher than that available on bonds bearing equivalent levels of interest rate risk, credit risk and other forms of risk, and that their prices will ultimately rise (relative to the market) to reflect their true value.

Likewise, the Fund may deviate from its normal investment policies and invest in taxable fixed-income and equity securities of an issuer of municipal bonds that the Fund already owns for the purpose of acquiring control of that issuer when Nuveen Advisory determines that such investment should enable the Fund to better maximize the value of its existing investment.

Also included within the general category of municipal bonds described in the Fund's Prospectus are participations in 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

13

purchase Municipal Lease Obligations where Nuveen Advisory believes the issuer has a strong incentive to continue making appropriations until maturity.

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 policies 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. Likewise, the Fund may deviate from its normal investment policies and invest in taxable fixed-income and equity securities of an issuer of municipal bonds that the Fund already owns for the purpose of acquiring control of that issuer when Nuveen Advisory determines that such investment should enable the Fund to better maximize the value of its existing investment.

Obligations of issuers of municipal bonds 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 bonds may be materially affected.

The Fund also may invest up to 10% of its net assets in securities of other open or closed-end investment companies that invest primarily in municipal bonds of the type in which the Fund may invest directly. The Fund will generally select obligations which may not be redeemed at the option of the issuer for approximately seven to nine years.

Additional Information on Municipal Bond Insurance

Original Issue Insurance. If interest or principal on a municipal bond is due, but the issuer fails to pay it, the insurer will make payments in the amount due to the fiscal agent no later than one business day after the insurer has been notified of the issuer's nonpayment. The fiscal agent will pay the amount due to the Fund after the fiscal agent receives evidence of the Fund's right to receive payment of the principal and/or interest, and evidence that all of the rights of payment due shall thereupon vest in the insurer. When the insurer pays the Fund the payment due from the issuer, the insurer will succeed to the Fund's rights to that payment.

Portfolio Insurance. Each portfolio insurance policy will be noncancellable and will remain in effect so long as the Fund is in existence, the Fund continues to own the municipal bonds covered by the policy, and the Fund pays the premiums for the policy. Each insurer generally will reserve the right at any time upon 90 days' written notice to the Fund to refuse to insure any additional bonds the Fund buys after the effective date of the notice. The Fund's Board of Trustees will generally reserve the right to terminate each policy upon seven day's written notice to an insurer if it determines that the cost of the policy is not reasonable in relation to the value of the insurance to the Fund.

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 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

15

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. The investment adviser 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. The Fund's investment adviser 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 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 Fixed Income Securities

Short-term tax-exempt fixed-income 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 fixed 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.

16

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 bonds 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 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 to partially hedge the portfolio against fluctuations in market value due to interest rate fluctuations by investment in

17

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, and the Fund has no present intention to use these strategies. For further information regarding these investment strategies and risks presented thereby, see Appendix D to this Statement of Additional Information.

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"); and repurchase agreements with maturities in excess of seven days.

18

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. Illiquid securities will be priced at a fair value as determined in good faith by the Board of Trustees or its delegate.

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 100%. 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 100% in particular years.

Other Investment Companies

The Fund may invest in securities of other open or closed-end investment companies that invest primarily in municipal bonds of the types in which the Fund may invest directly. The Fund generally expects to invest in other investment companies 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 bonds 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 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 the investment company relative to available municipal bond 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 in the section entitled "Risks," the net asset value and market value of leveraged shares will be more

19

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 bonds 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 bonds 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.

Miscellaneous Investments

The Fund, either singly or in conjunction with other funds advised or subadvised by Nuveen Advisory or an affiliate thereof, may (1) invest in taxable fixed-income or equity securities, and (2) invest for the purposes of acquiring control of an issuer whose municipal bonds (a) the Fund already owns and (b) have deteriorated or are expected shortly to deteriorate significantly in credit quality, provided Nuveen Advisory determines that such investment should enable the Fund to better maximize its existing investment in such issuer. Investment in taxable securities would result in a portion of your dividend being subject to regular federal income tax.

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 bonds) 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 "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

20

demand additional collateral from the issuer to increase the value of the collateral to at least that of the repurchase price, including interest.

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 seven.

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.

Peter R. Sawers 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, Robert P. Bremner, Lawrence H. Brown, Anne E. Impellizzeri, Peter R. Sawers and Judith M. Stockdale.

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, 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 Anne E. Impellizzeri, Chair, Robert P. Bremner, Lawrence H. Brown, Peter R. Sawers, William J. Schneider and Judith M. Stockdale.

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, and Lawrence H. Brown.

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 Judith M. Stockdale and Lawrence H. Brown.

The trustees of the Fund are also directors or trustees, as the case may be, of 30 Nuveen open-end funds and 82 Nuveen closed-end funds advised by Nuveen Advisory Corp. Mr. Schwertfeger is a director or trustee, as the case may be, of 18 Nuveen open-end and closed-end funds advised by Nuveen Institutional Advisory Corp. 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.

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."

No trustee who is not an interested person of the Fund 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.

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.

                                                                Amount of Total

Pursuant to an investment management agreement between Nuveen Advisory and the Fund, the Fund has agreed to pay for the services and facilities provided by Nuveen Advisory an annual management fee, payable on a monthly basis, according to the following schedule:

Average Daily Managed Assets                                     Management Fee
----------------------------                                     --------------
Up to $125 million                                                    .6500%
$125 million to $250 million                                          .6375%

$2 billion and over                                                   .5750%

If the Fund utilizes leverage through the issuance of MuniPreferred Shares in an amount equal to 35% of the Fund's total assets (including the amount obtained from leverage), the management fee calculated as a percentage of net assets attributable to Common Shares would be as follows:

Net Assets Attributable to Common Shares                          Management Fee
----------------------------------------                          --------------

$1 billion to $2 billion.......................................       .9231%
$2 billion and over............................................       .8846%

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:

Reducing Fund expenses in this manner will tend to increase the amount of income available for the Common Shareholders. Nuveen Advisory has not agreed to reimburse the Fund for any portion of its fees and expenses beyond ____________, 2010.

Unless earlier terminated as described below, the Fund's investment management agreement with Nuveen Advisory (the "management agreement") will remain in effect until ______, 2003. 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, 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 relationships 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.

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

28

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.

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.

DISTRIBUTIONS

As described in the Fund's Prospectus, initial distributions to Common Shareholders are expected to be declared approximately 45 days, and paid approximately 60 to 90 days, from the completion of the offering of the Common Shares, depending on market conditions. To permit the Fund to maintain a

29

more stable monthly distribution, the Fund will initially (prior to its first distribution), and may from time to time thereafter, distribute less than the entire amount of net investment income earned in a particular period. Such undistributed net investment income would be available to supplement future distributions, including distributions that might otherwise have been reduced by a decrease in the Fund's monthly net income due to fluctuations in investment income or expenses, or due to an increase in the dividend rate on the Fund's outstanding MuniPreferred Shares. As a result, the distributions paid by the Fund for any particular period may be more or less than the amount of net investment income actually earned by the Fund during such period. Undistributed net investment income will be added to the Fund's net asset value and, correspondingly, distributions from undistributed net investment income will be deducted from the Fund's net asset value.

For tax purposes, the Fund is currently required to allocate net capital gain and other taxable income, if any, between Common Shares and MuniPreferred Shares in proportion to total dividends paid to each class for the year in which such net capital gain or other taxable income is realized. For information relating to the impact of the issuance of MuniPreferred Shares on the distributions made by a Fund to Common Shareholders, see the Fund's Prospectus under "MuniPreferred Shares and Leverage."

While any MuniPreferred Shares are outstanding, the Fund may not declare any cash dividend or other distribution on its Common Shares unless at the time of such declaration (1) all accumulated dividends on the MuniPreferred Shares have been paid and (2) the net asset value of the Fund's portfolio (determined after deducting the amount of such dividend or other distribution) is at least 200% of the liquidation value of any outstanding MuniPreferred Shares. This latter limitation on the Fund's ability to make distributions on its Common Shares could under certain circumstances impair the ability of the Fund to maintain its qualification for taxation as a regulated investment company. See "Tax Matters."

DESCRIPTION OF SHARES

Common Shares

The Fund's Declaration of Trust (the "Declaration") authorizes the issuance of an unlimited number of Common Shares. The Common Shares being offered have a par value of $0.01 per share and, subject to the rights of holders of MuniPreferred Shares, if issued, have equal rights as to the payment of dividends and the distribution of assets upon liquidation of the Fund. The Common Shares being offered will, when issued, be fully paid and, subject to matters discussed in "Certain Provisions in the Declaration of Trust," non-assessable, and will have no pre-emptive or conversion rights or rights to cumulative voting. At any time when the Fund's MuniPreferred Shares are outstanding, Common Shareholders 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 such distributions. See "MuniPreferred Shares" below.

The Common Shares have been approved for listing on the _____________, subject to notice of issuance. The Fund intends to hold annual meetings of shareholders so long as the Common Shares are listed on a national securities exchange and such meetings are required as a condition to such listing.

30

Shares of closed-end investment companies may frequently trade at prices lower than net asset value. Shares of closed-end investment companies like the Fund that invest predominately in investment grade municipal bonds have during some periods traded at prices higher than net asset value and during other periods have traded at prices lower than net asset value. There can be no assurance that Common Shares or shares of other municipal funds will trade at a price higher than net asset value in the future. Net asset value will be reduced immediately following the offering after payment of the sales load and organization and offering expenses. Net asset value generally increases when interest rates decline, and decreases when interest rates rise, and these changes are likely to be greater in the case of a fund having a leveraged capital structure. Whether investors will realize gains or losses upon the sale of Common Shares will not depend upon a Fund's net asset value but will depend entirely upon whether the market price of the Common Shares at the time of sale is above or below the original purchase price for the shares. Since the market price of the Fund's Common Shares will be determined by factors beyond the control of the Fund, the Fund cannot predict whether the Common Shares will trade at, below, or above net asset value or at, below or above the initial public offering price. Accordingly, the Common Shares are designed primarily for long-term investors, and investors in the Common Shares should not view the Fund as a vehicle for trading purposes. See "Repurchase of Fund Shares; Conversion to Open-End Fund" and the Fund's Prospectus under "MuniPreferred Shares and Leverage" and "The Fund's Investments--Municipal Bonds."

MuniPreferred Shares

The Declaration authorizes the issuance of an unlimited number of MuniPreferred Shares in one or more classes or series, with rights as determined by the Board of Trustees of the Fund, by action of the Board of Trustees without the approval of the Common Shareholders.

The Fund's Board of Trustees has authorized an offering of MuniPreferred Shares (representing approximately 35% of the Fund's capital immediately after the time the MuniPreferred Shares are issued) approximately one to three months after completion of the offering of Common Shares. The Board has stated that the initial series of MuniPreferred Shares would pay cumulative dividends at rates determined weekly by providing for the periodic redetermination of the dividend rate through an auction or remarketing procedure. The Board of Trustees of the Fund has indicated that the liquidation preference, preference on distribution, voting rights and redemption provisions of the MuniPreferred Shares will be as stated below.

Limited Issuance of MuniPreferred Shares. Under the 1940 Act, the Fund could issue MuniPreferred Shares with an aggregate liquidation value of up to one-half of the value of the Fund's total net assets, measured immediately after issuance of the MuniPreferred Shares. "Liquidation value" means the original purchase price of the shares being liquidated plus any accrued and unpaid dividends. In addition, the Fund is not permitted to declare any cash dividend or other distribution on its Common Shares unless the liquidation value of the MuniPreferred Shares is less than one-half of the value of the Fund's total net assets (determined after deducting the amount of such dividend or distribution) immediately after the distribution. If the Fund sells all the Common Shares and MuniPreferred Shares discussed in this Prospectus, the liquidation value of the MuniPreferred Shares is expected to be approximately 35% of the value of the Fund's total net assets. The Fund intends to purchase or redeem MuniPreferred Shares, if necessary, to keep that fraction below one-half.

Distribution Preference. The MuniPreferred Shares have complete priority over the Common Shares as to distribution of assets.

31

Liquidation Preference. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Fund, holders of MuniPreferred Shares will be entitled to receive a preferential liquidating distribution (expected to equal the original purchase price per share plus accumulated and unpaid dividends thereon, whether or not earned or declared) before any distribution of assets is made to holders of Common Shares. After payment of the full amount of the liquidating distribution to which they are entitled, holders of MuniPreferred Shares will not be entitled to any further participation in any distribution of assets by the Fund. A consolidation or merger of the Fund with or into any Massachusetts business trust or corporation or a sale of all or substantially all of the assets of the Fund shall not be deemed to be a liquidation, dissolution or winding up of the Fund.

Voting Rights. In connection with any issuance of MuniPreferred Shares, the Fund must comply with Section 18(i) of the 1940 Act which requires, among other things, that MuniPreferred Shares be voting shares and have equal voting rights with Common Shares. Except as otherwise indicated in this Statement of Additional Information and except as otherwise required by applicable law, holders of MuniPreferred Shares will vote together with Common Shareholders as a single class.

In connection with the election of the Fund's trustees, holders of MuniPreferred Shares, voting as a separate class, will be entitled to elect two of the Fund's trustees, and the remaining trustees shall be elected by Common Shareholders and holders of MuniPreferred Shares, voting together as a single class. In addition, if at any time dividends on the Fund's outstanding MuniPreferred Shares shall be unpaid in an amount equal to two full years' dividends thereon, the holders of all outstanding MuniPreferred Shares, voting as a separate class, will be entitled to elect a majority of the Fund's trustees until all dividends in arrears have been paid or declared and set apart for payment.

The affirmative vote of the holders of a majority of the Fund's outstanding MuniPreferred Shares of any class or series, as the case may be, voting as a separate class, will be required to, among other things, (1) take certain actions which would affect the preferences, rights, or powers of such class or series or (2) authorize or issue any class or series ranking prior to the MuniPreferred Shares. Except as may otherwise be required by law, (1) 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, will be required to approve any conversion of the Fund from a closed-end to an open-end investment company and (2) the affirmative vote of the holders of at least two-thirds of the outstanding 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, 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 the By-laws. The affirmative vote of the holders of a majority of the outstanding 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 under Section 13(a) of the 1940 Act including, among other things, changes in a Fund's investment objectives or changes in the investment restrictions described as fundamental policies under "Investment Objectives and Policies--Investment Restrictions." The class or series vote of holders of MuniPreferred Shares described

32

above shall in each case be in addition to any separate vote of the requisite percentage of Common Shares and MuniPreferred Shares necessary to authorize the action in question.

The foregoing voting provisions will not apply with respect to the Fund's MuniPreferred Shares if, at or prior to the time when a vote is required, such shares shall have been (1) redeemed or (2) called for redemption and sufficient funds shall have been deposited in trust to effect such redemption.

Redemption, Purchase and Sale of MuniPreferred Shares by the Fund. The terms of the MuniPreferred Shares provide that they are redeemable at certain times, in whole or in part, at the original purchase price per share plus accumulated dividends, that the Fund may tender for or purchase MuniPreferred Shares and that the Fund may subsequently resell any shares so tendered for or purchased. Any redemption or purchase of MuniPreferred Shares by the Fund will reduce the leverage applicable to Common Shares, while any resale of shares by the Fund will increase such leverage.

The discussion above describes the Fund's Board of Trustees' present intention with respect to an offering of MuniPreferred Shares. The terms of the MuniPreferred Shares may be the same as, or different from, the terms described above, subject to applicable law and the Fund's Declaration.

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 or recapitalization 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

33

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 issues shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity. 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. 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. 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.

The provisions of the Declaration described above could have the effect of depriving the Common Shareholders of opportunities to sell their Common Shares at a premium over market value by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. The overall effect of these provisions is to render more difficult the accomplishment of a merger or the assumption of control by a third party. They provide, however, the advantage of potentially requiring persons seeking control of a Fund to negotiate with its management regarding the price to be paid and facilitating the continuity of the Fund's investment objectives and policies. The Board of Trustees of the Fund has considered the foregoing anti-takeover provisions and concluded that they are in the best interests of the Fund and its Common 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

34

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 on 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.

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 , or (b) impair the Fund's status as a regulated investment company under the Internal Revenue Code of 1986, as amended (the "Code") (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 ,(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

35

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 ____________________________. 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 will 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 will result in the Fund's shares 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 will 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. See the Fund's Prospectus under "Risks--Concentration Risk" and "Risks--Leverage Risk."

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.

TAX MATTERS

Federal Income Tax Matters

The following discussion of federal income tax matters is based upon the advice of Bell, Boyd & Lloyd LLC, special counsel to the Fund.

The Fund intends to qualify under Subchapter M of the Code for tax treatment as a regulated investment company and to satisfy certain conditions which will enable interest from municipal obligations, which is exempt from regular federal income taxes in the hands of the Fund, to qualify as "exempt- interest dividends" when distributed to the Fund's shareholders. In order to qualify for tax treatment as a regulated investment company, the Fund must satisfy certain requirements relating to the source of its income, diversification of its assets, and distributions of its income to shareholders. First, the Fund must derive at least 90% of its annual gross income (including tax-exempt interest) from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or foreign currencies, or other income (including but not limited to gains from options, futures and forward contracts) derived with respect to its business of investing in such stock, securities or currencies (the "90% gross income test"). Second, the Fund must diversify its holdings so that, at the close of each quarter of its taxable year, (i) at least 50% of the value of its total assets is comprised of cash, cash items, United States Government securities, securities of other regulated investment companies and other securities limited in respect of any one issuer to an amount not greater in value than 5% of the value 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 value of its total assets is invested in the securities of any one issuer (other than United States Government securities and 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.

As a regulated investment company, the Fund will not be subject to federal income tax in any taxable year with respect to "net investment income" (i.e., its "investment company taxable income," as that term is defined in the Code, determined without reference to the deduction for dividends paid) and "net capital gain" (i.e., the excess of the Fund's net long-term capital gain over its net short-term capital loss), provided that it distributes at least 90% of the sum of (i) its investment company taxable income (which includes dividends, taxable interest, taxable original issue discount and market discount income, income from securities lending, net short-term capital gain in excess of net long-term capital loss, and any other taxable income other than net capital gain and is reduced by deductible expenses) and (ii) its net tax-exempt interest (the excess of its gross tax-exempt interest income over certain disallowed deductions). The Fund may retain for investment its net capital gain. However, if the Fund retains any net capital gain or any investment company taxable income, it will be subject to tax at regular corporate rates on the amount retained. If the Fund retains any net capital gain, it may designate the retained amount as undistributed capital gains in a notice to its shareholders who, if subject to federal income tax on long-term capital gains, (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their share of such undistributed amount, and (ii) will be entitled to credit their proportionate shares of the tax paid by the Fund on such undistributed amount against their federal income tax liabilities, if any, and to claim refunds to the extent the credit exceeds such liabilities. For federal income tax purposes, the tax basis of shares owned by a shareholder of the Fund will be increased by an amount equal under current law to the difference between the amount of undistributed capital gains included in the shareholder's gross income and the tax deemed paid by the shareholder under clause (ii) of the preceding sentence. The

Fund intends to distribute at least annually to its shareholders all or substantially all of its net tax-exempt interest and any investment company taxable income and net capital gain.

Treasury regulations permit a regulated investment company, in determining its investment company taxable income and net capital gain, to elect (unless it has made a taxable year election for excise tax purposes) to treat all or part of any net capital loss, any net long-term capital loss or any net foreign currency loss incurred after October 31 as if it had been incurred in the succeeding year.

The Fund intends to qualify to pay "exempt-interest dividends" by satisfying the requirement that at the close of each quarter of the Fund's taxable year at least 50% of the value of its total assets consist of tax-exempt municipal obligations. Distributions from the Fund will constitute exempt- interest dividends to the extent of its tax-exempt interest income (net of expenses and amortized bond premium). Exempt-interest dividends distributed to Common Shareholders are excluded from gross income for federal income tax purposes, although they are required to be reported on the Common Shareholders' federal income tax returns. Gain from the sale or redemption of Common Shares, however, will be taxable to the Common Shareholders as capital gain (provided such Common Shares were held as capital assets) even though the increase in value of such Common Shares is attributable to tax-exempt interest income. In addition, gain realized by the Fund from the disposition of a tax-exempt municipal obligation that was purchased at a price less than the principal amount of the bond will be taxable to the Fund's shareholders as ordinary income to the extent of accrued market discount. Under the Code, interest on indebtedness incurred or continued to purchase or carry Common Shares, which interest is deemed to relate to exempt-interest dividends, will not be deductible by Common Shareholders for federal income tax purposes. Moreover, while exempt-interest dividends are excluded from gross income for federal income tax purposes, they may be subject to alternative minimum tax and may have other collateral tax consequences. The Fund will not invest in AMT Bonds. See "Investment Policies and Techniques." Different alternative minimum rules apply to individuals and to corporations. Taxpayers that may be subject to the alternative minimum tax should consult their advisers before investing in Common Shares.

Distributions by the Fund of net interest received from certain taxable temporary investments (such as certificates of deposit, commercial paper and obligations of the U.S. Government, its agencies and instrumentalities) and net short-term capital gain realized by the Fund, if any, will be taxable to Common Shareholders as ordinary income whether received in cash or additional shares. Any net long-term capital gain realized by the Fund and distributed to Common Shareholders in cash or additional shares will be taxable to Common Shareholders as long-term capital gain regardless of the length of time investors have owned shares of the Fund. Taxable distributions will not be eligible for the dividends received deduction allowed to corporations. Distributions by the Fund to Common Shareholders that do not constitute ordinary income dividends, capital gain dividends or exempt-interest dividends will be treated as a return of capital to the extent of (and in reduction of) the Common Shareholder's tax basis in his or her shares. Any excess will be treated as gain from the sale of his or her shares, as discussed below.

The Internal Revenue Service's position in a published revenue ruling indicates that the Fund is required to designate distributions paid with respect to its Common Shares and its MuniPreferred Shares as consisting of a portion of each type of income distributed by the Fund. The portion of each type of income deemed received by the holders of each class of shares will be equal to the portion of total Fund dividends received by such class. Thus, the Fund will designate dividends paid as exempt-interest dividends in a manner that allocates such dividends between the holders of the Common Shares and the holders of MuniPreferred Shares, in proportion to the total dividends paid to each such class during or with respect to the taxable year, or otherwise as required by applicable law. Capital gain dividends and ordinary income dividends will similarly be allocated between the two classes.

If the Fund engages in hedging transactions involving financial futures and options, these transactions will be subject to special tax rules, the effect of which may be to accelerate income to the Fund, defer the Fund's losses, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains and convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to Common Shareholders.

Prior to purchasing shares in the Fund, an investor should carefully consider the impact of dividends or distributions which are expected to be or have been declared, but not paid. Any dividend or distribution declared shortly after a purchase of such shares prior to the record date will have the effect of reducing the per share net asset value by the per share amount of the dividend or distribution.

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.

The sale or exchange of Common Shares normally will result in capital gain or loss to the Common Shareholders who hold their Common Shares as capital assets. However, any loss on the sale or exchange of a Common Share that has been held for six months or less will be disallowed to the extent of any distribution of exempt-interest dividends received with respect to such Common Share. Generally, a Common Shareholder's gain or loss will be long-term gain or loss if the shares have been held for more than one year. If a shareholder sells or otherwise disposes of Common Shares before holding them for more than six months, however, any loss on the sale or other disposition of such Common Shares shall be treated as a long-term capital loss to the extent of any capital gain dividends received by the Common Shareholder (or amounts credited to the Common Shareholder as an undistributed capital gain) with respect to such Common Shares. Present law taxes both long- and short-term capital gains of corporations at the rates applicable to ordinary income. For non-corporate taxpayers, however, net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) with respect to securities is taxed at a maximum rate of 20%, while short-term capital gain and other ordinary income is taxed at a maximum

38

rate of 38.6% in 2002 and 2003, 37.6% in 2004 and 2005, and 35% thereafter until 2011, when the maximum rate on ordinary income will revert to 39.6% unless amended by Congress. The maximum long-term capital gain rate is 18% for capital assets that are held for more than five years and whose holding periods begin after December 31, 2000. Because of the limitations on itemized deductions and the deduction for personal exemptions applicable to higher income taxpayers, the effective tax rate may be higher in certain circumstances.

All or a portion of a sales charge paid in purchasing Common Shares cannot be taken into account for purposes of determining gain or loss on the redemption or exchange of such shares within 90 days after their purchase to the extent shares of the Fund or another fund are subsequently acquired without payment of a sales charge pursuant to a reinvestment right. Any disregarded portion of such charge will result in an increase in the Common Shareholder's tax basis in the shares subsequently acquired. In addition, no loss will be allowed on the redemption or exchange of Common Shares if the Common Shareholder purchases other shares of the Fund (whether through reinvestment of distributions or otherwise) or the Common Shareholder acquires or enters into a contract or option to acquire securities that are substantially identical to shares of the Fund within a period of 61 days beginning 30 days before and ending 30 days after such redemption or exchange. If disallowed, the loss will be reflected in an adjustment to the basis of the shares acquired.

In order to avoid a 4% federal excise tax, the Fund must distribute or be deemed to have distributed by December 31 of each calendar year at least 98% of its taxable ordinary income for such year, at least 98% of its capital gain net income (the excess of its realized capital gains over its realized capital losses, generally computed on the basis of the one-year period ending on October 31 of such year) and 100% of any taxable ordinary income and any excess of realized capital gains over realized capital losses for the prior year that was not distributed during such year and on which the Fund paid no federal income tax. For purposes of the excise tax, a regulated investment company may reduce its capital gain net income (but not below its net capital gain) by the amount of any net ordinary loss for the calendar year. The Fund intends to make timely distributions in compliance with these requirements and consequently it is anticipated that it generally will not be required to pay the excise tax.

If in any year the Fund should fail to qualify under Subchapter M for tax treatment as a regulated investment company, the Fund would incur a regular corporate federal income tax upon its income for that year, and distributions to its Common Shareholders would be taxable to Common Shareholders as ordinary dividend income for federal income tax purposes to the extent of the Fund's earnings and profits.

The Fund is required in certain circumstances to withhold a percentage of taxable dividends and certain other payments paid to non-corporate holders of shares who have not furnished to the Fund their correct taxpayer identification numbers (in the case of individuals, their Social Security number) and certain certifications, or who are otherwise subject to backup withholding. The backup withholding percentage will be 30% in 2002 and 2003, 29% in 2004 and 2005, and 28% thereafter until 2011, when the percentage will revert to 31% unless amended by Congress. Backup withholding is not an additional tax and any amounts withheld may be credited against the shareholder's federal income tax liability.

The foregoing is a general and abbreviated summary of the provisions of the Code and Treasury Regulations presently in effect as they directly govern the taxation of the Fund and its Common Shareholders. For complete provisions, reference should be made to the pertinent Code sections and Treasury Regulations. The Code and Treasury Regulations are subject to change by legislative or administrative action, and any such change may be retroactive with respect to Fund transactions. Common Shareholders are advised to consult their own tax

advisors for more detailed information concerning the federal taxation of the Fund and the income tax consequences to its Common Shareholders.

APPENDIX A

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

A-1

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.

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.

A-2

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.

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:

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

. 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-3

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-1' for the highest quality obligations to `D' for the lowest. These categories are as follows:

A-1  A short-term obligation rated `A-1' is rated in the highest category by
     Standard & Poor's. The obligor's capacity to meet its financial commitment
     on the obligation is strong. Within this category, certain obligations are
     designated with a plus sign (+). This indicates that the obligor's capacity
     to meet its financial commitment on these obligations is extremely strong.

A-2  A short-term obligation rated `A-2' is somewhat more susceptible to the
     adverse effects of changes in circumstances and economic conditions than
     obligations in higher rating categories. However, the obligor's capacity to
     meet its financial commitment on the obligation is satisfactory.

A-3  A short-term obligation rated `A-3' 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.

B    A short-term obligation rated `B' is regarded as having significant
     speculative characteristics. The obligor currently has the capacity to meet
     its financial commitment on the obligation; however, it faces major ongoing
     uncertainties which could lead to the obligor's inadequate capacity to meet
     its financial commitment on the obligation.

C    A short-term obligation rated `C' 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.

D    A short-term 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.

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 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.

A-4

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 which 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.

A-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.

Commercial Paper

Issuers rated Prime-1 (or related 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.

A-6

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

Issuers rated Prime-2 (or related 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 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 related 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. Adequate alternate liquidity is maintained.

Issuers rated Not Prime do not fall within any of the Prime rating categories.

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

A-7

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 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.

A-8

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.

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, companies whose outlooks are `stable' could be 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. In these cases, the Rating Outlook may be described as evolving.

APPENDIX C

DESCRIPTION OF INSURERS

Set forth below is information about the various municipal bond insurers with whom the Fund intends to maintain specific insurance policies for particular municipal bonds or policies of portfolio insurance. The information in this Appendix is based on information supplied by the insurers, and the Fund cannot verify its accuracy and completeness.

AMBAC ASSURANCE CORPORATION ("AMBAC ASSURANCE")

Payment Pursuant to Financial Guaranty Insurance Policy

Ambac Assurance has made a commitment to issue a financial guaranty insurance policy (the "Financial Guaranty Insurance Policy") relating to the bonds effective as of the date of issuance of the bonds. Under the terms of the Financial Guaranty Insurance Policy, Ambac Assurance will pay to The Bank of New York, in New York, New York or any successor thereto (the "Insurance Trustee") that portion of the principal of and interest on the bonds which shall become Due for Payment but shall be unpaid by reason of Nonpayment by the Obligor (as such terms are defined in the Financial Guaranty Insurance Policy). Ambac Assurance will make such payments to the Insurance Trustee on the later of the date on which such principal and interest becomes Due for Payment or within one business day following the date on which Ambac Assurance shall have received notice of Nonpayment from the Trustee/Paying Agent. The insurance will extend for the term of the bonds and, once issued, cannot be canceled by Ambac Assurance.

The Financial Guaranty Insurance Policy will insure payment only on stated maturity dates and on mandatory sinking fund installment dates, in the case of principal, and on stated dates for payment, in the case of interest. If the bonds become subject to mandatory redemption and insufficient funds are available for redemption of all outstanding bonds, Ambac Assurance will remain obligated to pay principal of and interest on outstanding bonds on the originally scheduled interest and principal payment dates including mandatory sinking fund redemption dates. In the event of any acceleration of the principal of the bonds, the insured payments will be made at such times and in such amounts as would have been made had there not been an acceleration.

In the event the Bond Registrar has notice that any payment of principal of or interest on a bond which has become Due for Payment and which is made to a Holder by or on behalf of the Obligor has been deemed a preferential transfer and theretofore recovered from its registered owner pursuant to the United States Bankruptcy Code in accordance with a final, nonappealable order of a court of competent jurisdiction, such registered owner will be entitled to payment from Ambac Assurance to the extent of such recovery if sufficient funds are not otherwise available.

The Financial Guaranty Insurance Policy does not insure any risk other than Nonpayment, as defined in the Policy. Specifically, the Financial Guaranty Insurance Policy does not cover:

1. payment on acceleration, as a result of a call for redemption (other than mandatory sinking fund redemption) or as a result of any other advancement of maturity.

2. payment of any redemption, prepayment or acceleration premium.

3. nonpayment of principal or interest caused by the insolvency or negligence of any Trustee or Paying Agent, if any.

If it becomes necessary to call upon the Financial Guaranty Insurance Policy, payment of principal requires surrender of bonds to the Insurance Trustee together with an appropriate instrument of assignment so as to permit ownership of such bonds to be registered in the name of Ambac Assurance to the extent of the payment under the Financial Guaranty Insurance Policy. Payment of interest pursuant to the Financial Guaranty Insurance Policy requires proof of Holder entitlement to interest payments and an appropriate assignment of the Holder's right to payment to Ambac Assurance.

Upon payment of the insurance benefits, Ambac Assurance will become the owner of the bond, appurtenant coupon, if any, or right to payment of principal or interest on such bond and will be fully subrogated to the surrendering Holder's rights to payment.

Ambac Assurance

Ambac Assurance Corporation ("Ambac Assurance") is a Wisconsin-domiciled stock insurance corporation regulated by the Office of the Commissioner of Insurance of the State of Wisconsin and licensed to do business in 50 states, the District of Columbia, the Territory of Guam and the Commonwealth of Puerto Rico, with admitted assets of approximately $5,587,000,000 (unaudited) and statutory capital of approximately $3,453,000,000 (unaudited) as of June 30, 2002. Statutory capital consists of Ambac Assurance's policyholders' surplus and statutory contingency reserve. Standard & Poor's Credit Markets Services, a division of The McGraw-Hill Companies, Moody's Investors Service and Fitch, Inc. have each assigned a triple-A financial strength rating to Ambac Assurance. Ambac Assurance has obtained a ruling from the Internal Revenue Service to the effect that the insuring of an obligation to Ambac Assurance will not affect the treatment for federal income tax purposes of interest on such obligation and that insurance proceeds representing maturing interest paid by Ambac Assurance under policy provisions substantially identical to those contained in its municipal bond insurance policy shall be treated for federal income tax purposes in the same manner as if such payments were made by the issuer of the bonds.

Ambac Assurance makes no representation regarding the bonds or the advisability of investing in the bonds and makes no representation regarding, nor has it participated in the preparation of, the Prospectus and Statement of Additional Information, other than the information supplied by Ambac Assurance and presented under this heading "Ambac Assurance Corporation."

FINANCIAL GUARANTY INSURANCE COMPANY ("FINANCIAL GUARANTY")

Concurrently with the issuance of the Bonds, Financial Guaranty Insurance Company ("Financial Guaranty") will issue its Municipal Bond New Issue Insurance Policy (the "Policy") for the Bonds described in the Policy (as used under this heading, the "Bonds"). The Policy unconditionally guarantees the payment of that portion of the principal or accreted value (if applicable) of and interest on the Bonds which has become due for payment, but shall be unpaid by reason of nonpayment by the issuer of the Bonds (the "Issuer"). Financial Guaranty will make such payments to State Street Bank and Trust Company, N.A., or its successor as its agent (the "Fiscal Agent"), on the later of the date on which such principal, accreted value or interest (as applicable) is due or on the business day next following the day on which Financial Guaranty shall have received telephonic or telegraphic notice, subsequently confirmed in writing, or written notice by registered or certified mail, from an owner of Bonds or the Paying Agent of the nonpayment of such amount by the Issuer. The Fiscal Agent will disburse such amount due on any Bond to its owner upon receipt by the Fiscal Agent of evidence satisfactory to the Fiscal Agent of the owner's right to receive payment of the principal, accreted value or interest (as applicable) due for payment and evidence, including any appropriate instruments of assignment, that all of such owner's rights to payment of such principal, accreted value or interest (as applicable) shall be vested in Financial Guaranty. The term "nonpayment" in respect of a Bond includes any payment of principal, accreted value or interest (as applicable) made to an owner of a Bond which has been recovered from such owner pursuant to the United States Bankruptcy Code by a trustee in bankruptcy in accordance with a final, nonappealable order of a court having competent jurisdiction.

The Policy is non-cancellable and the premium will be fully paid at the time of delivery of the Bonds. The Policy covers failure to pay principal or accreted value (if applicable) of the Bonds on their respective stated maturity dates or dates on which the same shall have been duly called for mandatory sinking fund redemption, and not on any other date on which the Bonds may have been otherwise called for redemption, accelerated or advanced in maturity, and covers the failure to pay an installment of interest on the stated date for its payment.

C-3

Generally, in connection with its insurance of an issue of municipal securities, Financial Guaranty requires, among other things, (i) that it be granted the power to exercise any rights granted to the holders of such securities upon the occurrence of an event of default, without the consent of such holders, and that such holders may not exercise such rights without Financial Guaranty's consent, in each case so long as Financial Guaranty has not failed to comply with its payment obligations under its insurance policy; and
(ii) that any amendment or supplement to or other modification of the principal legal documents be subject to Financial Guaranty's consent. The specific rights, if any, granted to Financial Guaranty in connection with its insurance of the Bonds are set forth in the prospectus. Reference should be made as well to such description for a discussion of the circumstances, if any, under which the Fund will provide additional or substitute credit enhancement, and related matters.

The Policy is not covered by the Property/Casualty Insurance Security Fund specified in Article 76 of the New York Insurance Law or by the Florida Insurance Guaranty Association (Florida Insurance Code, (S)(S) 631.50 et seq.).

C-4

RATINGS

The above municipal bond insurers have insurance claims-paying ability ratings of AAA from S&P and Aaa from Moody's. Financial Guaranty also has an insurance claims-paying ability rating of AAA from Fitch. An S&P insurance claims-paying ability rating is an assessment of an operating insurance company's financial capacity to meet obligations under an insurance policy in accordance with its terms. An insurer with an insurance claims-paying ability rating of AAA has the highest rating assigned by S&P. Capacity to honor insurance contracts is adjudged by S&P to be extremely strong and highly likely to remain so over a long period of time. A Moody's insurance claims-paying ability rating is an opinion of the ability of an insurance company to repay punctually senior policyholder obligations and claims. An insurer with an insurance claims-paying ability rating of Aaa is adjudged by Moody's to be of the best quality. In the opinion of Moody's, the policy obligations of an insurance company with an insurance claims-paying ability rating of Aaa carry the smallest degree of credit risk and, while the financial strength of these companies is likely to change, such changes as can be visualized are most unlikely to impair the company's fundamentally strong position.

An insurance claims-paying ability rating by S&P or Moody's does not constitute an opinion on any specific contract in that such an opinion can only be rendered upon the review of the specific insurance contract. Furthermore, an insurance claims-paying ability rating does not take into account deductibles, surrender or cancellation penalties or the timeliness of payment, nor does it address the ability of a company to meet nonpolicy obligations (i.e., debt contracts).

The assignment of ratings by S&P or Moody's to debt issues that are fully or partially supported by insurance policies, contracts or guarantees is a separate process from the determination of claims-paying ability ratings. The likelihood of a timely flow of funds from the insurer to the trustee for the bondholders is a key element in the rating determination for such debt issues.

S&P's and Moody's ratings are not recommendations to buy, sell or hold the municipal bonds insured by policies issued by AMBAC Assurance, Financial Security, MBIA or Financial Guaranty and such ratings may be subject to revision or withdrawal at any time by the rating

C-5

agencies. Any downward revision or withdrawal of either or both ratings may have an adverse effect on the market price of the municipal bonds insured by policies issued by AMBAC Assurance, Financial Security, MBIA or Financial Guaranty.

S&P's ratings of AMBAC Assurance, Financial Security, MBIA and Financial Guaranty should be evaluated independent of Moody's ratings. Any further explanation as to the significance of the ratings may be obtained only from the applicable rating agency. See Appendix A for more information about ratings by Moody's and S&P.

APPENDIX D

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.

D-1

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.

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.

PERFORMANCE RELATED AND COMPARATIVE INFORMATION

The Fund may be a suitable investment for a shareholder that is thinking of adding bond investments to his portfolio to balance the appreciated stocks that the shareholder is holding. Municipal bonds can provide double, tax-free income (exempt from regular federal and state income taxes) for residents of that state.

The Fund may quote certain performance-related information and may compare certain aspects of its portfolio and structure to other substantially similar closed-end funds as categorized by Lipper, Inc. ("Lipper"), Morningstar or other independent services. Comparison of the Fund to an alternative investment should be made with consideration of differences in features and expected performance. The Fund may obtain data from sources or reporting services, such as Bloomberg Financial ("Bloomberg") and Lipper, that the Fund believes to be generally accurate. According to Thomson Wealth Management, Nuveen is the leading sponsor of municipal closed-end exchange-traded bond funds measured by the number of funds (87) and fund assets under management ($33 billion) as of August 31, 2002.

Municipal Bond/Equity Portfolios May
Provide Attractive Returns and Reduced Risk

Nuveen research shows that, over the past 20 years, a portfolio of 20% municipal bonds and 80% equities produced 99% of the annual after-tax return of an all-equity portfolio with measurably less risk.

These conclusions are based on research done by Nuveen Investments using the following portfolio assumptions: Municipal bonds are represented by the Lehman Brothers Long Municipal Index. Treasury Bonds are represented by Lehman Brothers Long Treasury Index. Equities are the S&P 500 stocks as tracked by the Ibbotson Associates Large Company Stock Index. It is not possible to invest directly in any of these indexes. Hypothetical portfolios using varying percentages of municipal bonds or Treasury bonds and equities, in each case totaling 100%, were constructed, and the investment results and volatility determined, for every year from 1982 through 2001.

All investment income generated by the portfolio was considered to be reinvested annually, along with the after-tax proceeds of an arbitrarily assumed 20% annualized turnover rate. The allocation between the two assets was allowed to fluctuate within a 5% band around its target before rebalancing. No provision was made for investment fees or commissions. Investment income was taxed at the historically appropriate rate for an individual with $100,000 in taxable income in 2001 dollars. Net capital gains taxes, if any, were deducted at the rate appropriate for the period. At the end of 2001, the portfolios were fully liquidated to recognize the existing tax liability.

This study was based on historical data gathered from sources Nuveen Investments considers to be reliable and consistent. The results produced by this study in no way should be considered representative of the past performance of any actual investment product or predictive of future investment expectations and performance for the municipal market or any actual investment products.

In particular, municipal bond rates during the early portion of the 20-year period covered by this research were higher than current municipal rates, and returns for municipal bonds going forward will likely be less than those shown in the chart.

Market price is affected by many factors, including market interest rates, income tax rates, the common shares' net asset value and dividend stability, the portfolio's duration, call protection and credit quality, analyst recommendations, and other market factors. Any of these factors individually or collectively may, at any given time, be as or more important to market price than annualized dividend rates. A positive correlation does not necessarily mean that higher dividends cause or result in higher market prices, and you should not assume that any particular level of dividends will result in any particular market price. In addition, the positive correlation between dividends and market price of this group of funds does not necessarily mean that every fund in the group exhibits a positive correlation between dividend and market price, and it is possible that the Fund may not exhibit such a correlation. There can be no assurance that the correlation suggested by the above data will continue in the future.

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.

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-3

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

C-4

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 Underwriting Agreement to be filed as Exhibit h.1 to this 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.

ARTICLE II

NATURE AND PURPOSE OF TRUST

The Trust is a voluntary association (commonly known as a business trust) of the type referred to in Chapter 182 of the General Laws of the Commonwealth of Massachusetts. The Trust is not intended to be, shall not be deemed to be, and shall not be treated as, a general or a limited partnership, joint venture, corporation or joint stock company, nor shall the Trustees or Shareholders or any of them for any purpose be deemed to be, or be treated in any way whatsoever as though they were, liable or responsible hereunder as partners or joint venturers. The purpose of the Trust is to engage in, operate and carry on the business of a closed-end management investment company and to do any and all acts or things as are necessary, convenient, appropriate incidental or customary in connection therewith, including, without limitation, the following:

to hold, invest, and reinvest its funds, and in connection therewith to hold part of all of its funds in cash, and to purchase or


-3-

otherwise sell, assign, negotiate, transfer, exchange or otherwise dispose of or turn to account or realize upon securities and other negotiable or non-negotiable instruments, obligations and evidences of indebtedness created or issued by any person, firms, associations, corporations, syndicates, combinations, and other negotiable or non-negotiable instruments, obligation and evidences of indebtedness; and to exercise, as owner or holder of any securities or other instruments, all rights, powers, and privileges in respect thereof; and to do any and all acts and things for the preservation, protection and improvement of any and all such securities or other instruments, and, in general, to conduct the business of a closed-end investment company as that term is defined in the 1940 Act; and

To engage in any lawful act or activity for which business trusts may be organized under Massachusetts law.

The Trust set forth in this instrument shall be deemed made in the Commonwealth of Massachusetts, and it is created under and is to be governed by and construed and administered according to the laws of said Commonwealth. The Trust shall be of the type commonly called a business trust, and without limiting the provisions hereof, the Trust may exercise all powers which are ordinarily exercised by such a trust. No provision of this Declaration shall be effective to require a waiver of compliance with any provision of the Securities Act of 1933, as amended, or the 1940 Act, or of any valid rule, regulation or order of the Commission thereunder.

The enumeration herewith of the objects and purposes of the Trust shall be construed as powers as well as objects and purposes and shall not be deemed to exclude by inference any powers, objects or purposes which the Trust may lawfully pursue or exercise.

ARTICLE III

REGISTERED AGENT; PRINCIPAL PLACE OF BUSINESS

The name of the registered agent of the Trust is CT Corporation System at 101 Federal Street, Boston, Massachusetts. The principal place of business of the Trust is 333 West Wacker Drive, Chicago, Illinois 60606.

ARTICLE IV

BENEFICIAL INTEREST

Section 1. Shares of Beneficial Interest. The beneficial interest in the Trust shall be divided into such transferable Shares of beneficial interest, of such classes or series, and of such designations and par values (if any), and with such rights, preferences, privileges and restrictions as shall be determined by the Trustees in their sole discretion, without Shareholder approval, from time to time. The number of Shares is unlimited and each Share shall be fully paid and nonassessable. There shall be no cumulative voting. Subject to any provision in a Statement (as defined in Section 2 below) to the contrary, the Trustees shall have full power and authority, in their sole discretion and without obtaining any prior authorization or vote of the Shareholders of the Trust or of the Shareholders of any series or class of Shares, to create and establish (and to change in any manner) Shares or any series or classes thereof with such preferences, voting powers, rights and privileges as the Trustees may from time to time determine; to divide or combine the Shares or the Shares of any series or classes thereof into a greater or lesser number including, without limitation, such a division or combination accomplished by means of a stock split or a reverse stock split, without thereby changing their proportionate beneficial interest in the Trust; to classify or reclassify any issued Shares into one or more series or classes of Shares; to abolish any one or more series or classes of Shares; and to take such other action with respect to the Shares as the Trustees may deem desirable. The Shares shall initially be divided into two classes, a class of an unlimited number of common Shares, $0.01 par value (the "Common Shares"), and a class of an unlimited number of preferred Shares, $0.01 par value (the "Preferred Shares"), each having the powers, preferences, rights, qualifications, limitations and restrictions described below:

(a) Preferred Shares. The Preferred Shares shall be issued from time to time in one or more classes or series with such distinctive serial designations and (i) may have such voting powers, full or limited; (ii) may be subject to redemption at such time or times and at such price or prices; (iii) may be entitled to receive dividends (which may be cumulative or noncumulative) at such rate or rates, on such conditions, and at such times, and payable in preference to, or in such relation to, the dividends payable on any other class or classes of Shares; (iv) may have such rights upon the termination of, or upon any distribution of the assets of, the Trust; (v) may be made convertible into, or exchangeable for, Shares of any other class or classes or of any other series of the same or any other class or classes of Shares of the Trust, at such price or prices or at such rates of exchange and


-5-

with such adjustments; and (vi) shall have such other relative, participating, optional or other special rights, qualifications, limitations or restrictions thereof, all as shall hereafter be stated and expressed in the resolution or resolutions providing for the issue of such Preferred Shares from time to time adopted by the Trustees (or a Committee thereof) in accordance with Section 2 of this Article IV. Any of such matters may be made dependent upon facts ascertainable outside this Declaration of Trust, or outside the resolution or resolutions providing for the issue of such Preferred Shares.

(b) Common Shares.

(i) Subject to the rights of the holders of the Preferred Shares, in the event of the termination of the Trust the holders of the Common Shares shall be entitled to receive pro rata the net distributable assets of the Trust.

(ii) The holders of the Common Shares shall not, as such holders, have any right to acquire, purchase or subscribe for any Common Shares or securities of the Trust which it may hereafter issue or sell, other than such right, if any, as the Trustees in their discretion may determine.

(iii) Subject to the rights of the holders of the Preferred Shares, dividends or other distributions, when, as and if declared by the Trustees, shall be shared equally by the holders of Common Shares on a share for share basis. The Trustees may direct that any dividends or other distributions or any portion thereof as declared and distributed shall be paid in cash to the holder, or, alternatively, may direct that any such dividends be reinvested in full and fractional Shares of the Trust [if such holder elects to have them reinvested.]

(iv) The Trustees may hold as treasury shares (of the same or some other series), reissue for such consideration and on such terms as they may determine, or cancel any Common Shares of any series reacquired by the Trust at their discretion from time to time. Shares shall not entitle the Shareholder to any title in or to the whole or any part of the Trust.

(v) Common Shares may be issued from time to time, without the vote of the Shareholders (or, if the Trustees in their sole discretion deem advisable, with a vote of Shareholders), either for cash or for such other consideration (which may be in any one or more instances a certain specified consideration or certain specified considerations) and on such terms as the Trustees, from time to time, may deem advisable, and the Trust may in such manner acquire other assets (including the


-6-

acquisition of assets subject to, and in connection with the assumption of liabilities).

(vi) The Trust may issue Common Shares in fractional denominations to the same extent as its whole Shares, and Shares in fractional denominations shall be Common Shares having proportionately to the respective fractions represented thereby all the rights of whole Shares, including, without limitation, the right to vote, the right to receive dividends and distributions and the right to participate upon termination of the Trust, but excluding the right to receive a certificate representing fractional Shares.

Section 2. Establishment of Class or Series of Shares. The establishment and designation of any class or series of Shares, including any Preferred Shares issued hereunder, shall be effective upon the adoption of a resolution by the initial Trustee, or by a majority of the Trustees then in office (or a Committee thereof) setting forth such establishment and designation and the relative rights and preferences of the Shares of such class or series as set forth in a written statement either executed by the President or a Vice President of the Trust, or executed by a majority of the Trustees then in office (the "Statement"). At any time that there are no Shares outstanding of any particular class or series previously established and designated, the Trustees (or a Committee thereof) may by a majority vote abolish that class or series and the establishment and designation thereof. Notwithstanding any provision of this Declaration of Trust to the contrary, no such Statement establishing and designating any class or series of Shares shall constitute an amendment to or a part of this Declaration of Trust.

Section 3. Ownership Of Shares. The ownership and transfer of Shares shall be recorded on the books of the Trust or its transfer or similar agent. No certificates certifying the ownership of Preferred Shares shall be issued except as the Trustees may otherwise determine from time to time. The Trustees may make such rules as they consider appropriate for the issuance of Share certificates, transfer of Shares and similar matters. The record books of the Trust, as kept by the Trust or any transfer or similar agent of the Trust, shall be conclusive as to who are the holders of the Shares and as to the number of Shares held from time to time by each Shareholder.

Section 4. No Preemptive Rights, Etc. The holders of Shares of any class or series shall not, as such holders, have any right to acquire, purchase or subscribe for any Shares or securities of the Trust which it may hereafter issue or sell, other than such right, if any, as the Trustees in their discretion may determine. The holders of Shares of any class or series shall have no appraisal rights with respect to their Shares and, except as otherwise


-7-

determined by resolution of the Trustees in their sole discretion, shall have no exchange or conversion rights with respect to their Shares.

Section 5. Status of Shares and Limitation of Personal Liability. Shares shall be deemed to be personal property giving only the rights provided in this instrument. Every Shareholder by virtue of having become a Shareholder shall be held to have expressly assented and agreed to the terms of this Declaration of Trust and to have become a party thereto. The death of a Shareholder during the continuance of the Trust shall not operate to terminate the same nor entitle the representative of any deceased Shareholder to an accounting or to take any action in court or elsewhere against the Trust or the Trustees, but only to the rights of said decedent under this Trust. Ownership of property shall not entitle the Shareholder to any title in or to the whole or any part of the Trust Property or right to call for a partition or division of the same or for an accounting. Neither the Trustees, nor any officer, employee or agent of the Trust shall have any power to bind any Shareholder personally or to call upon any Shareholder for the payment of any sum of money or assessment whatsoever other than such as the Shareholder may at any time personally agree to pay by way of subscription for any Shares or otherwise.

ARTICLE V

THE TRUSTEES

Section 1. Management of the Trust. The business and affairs of the Trust shall be managed by the Trustees, and they shall have all powers necessary and desirable to carry out that responsibility.

Section 2. Qualification and Number. Each Trustee shall be a natural person. A Trustee need not be a shareholder, a citizen of the United States, or a resident of the Commonwealth of Massachusetts. By the vote or consent of the initial Trustee, or by a majority of Trustees as may subsequently then be in office, the initial Trustee or any subsequent Trustees may fix the number of Trustees at a number not less than two (2) nor more than twelve (12) and may fill the vacancies created by any such increase in the number of Trustees. Except as determined from time to time by resolution of the Trustees, no decrease in the number of Trustees shall have the effect of removing any Trustee from office prior to the expiration of his term, but the number of Trustees may be decreased in conjunction with the removal of a Trustee pursuant to Section 4 of Article V.

Section 3. Term and Election. Each Trustee shall hold office until the next meeting of Shareholders called for the purpose of considering the election or re-election of such Trustee or of a successor to such Trustee, and


-8-

until his successor is elected and qualified, and any Trustee who is appointed by the Trustees in the interim to fill a vacancy as provided hereunder shall have the same remaining term as that of his predecessor, if any, or such term as the Trustees may determine. Any vacancy resulting from a newly created Trusteeship or the death, resignation, retirement, removal, or incapacity of a Trustee may be filled by the affirmative vote or consent of a majority of the Trustees then in office.

Section 4. Resignation and Removal. Any Trustee may resign his trust or retire as a Trustee (without need for prior or subsequent accounting except in the event of removal) by an instrument in writing signed by him and delivered or mailed to the Chairman, if any, the President or the Secretary and such resignation or retirement shall be effective upon such delivery, or at a later date according to the terms of the instrument. Any Trustee may be removed from office only for "Cause" (as hereinafter defined) and only (i) by action of at least sixty-six and two-thirds percent (66 2/3%) of the outstanding Shares of the class or classes of Shares that elected such Trustee, or (ii) by written instrument, signed by at least sixty-six and two-thirds percent (66 2/3%) of the remaining Trustees, specifying the date when such removal shall become effective. "Cause" shall require willful misconduct, dishonesty, fraud or a felony conviction.

Section 5. Vacancies. The death, declination, resignation, retirement, removal, or incapacity, of the Trustees, or any one of them, shall not operate to annul the Trust or to revoke any existing agency created pursuant to the terms of this Declaration of Trust. Whenever a vacancy in the number of Trustees shall occur, until such vacancy is filled as provided herein, or the number of Trustees as fixed is reduced, the Trustees in office, regardless of their number, shall have all the powers granted to the Trustees, and during the period during which any such vacancy shall occur, only the Trustees then in office shall be counted for the purposes of the existence of a quorum or any action to be taken by such Trustees.

Section 6. Ownership of Assets of the Trust. The assets of the Trust shall be held separate and apart from any assets now or hereafter held in any capacity other than as Trustee hereunder by the Trustees or any successor Trustees. All of the assets of the Trust shall at all times be considered as automatically vested in the Trustees as shall be from time to time in office. Upon the resignation, retirement, removal, incapacity or death of a Trustee, such Trustee shall automatically cease to have any right, title or interest in any of the Trust property, and the right, title and interest of such Trustee in the Trust property shall vest automatically in the remaining Trustees. Such vesting and cessation of title shall be effective without the execution or delivery of any conveyancing or other instruments. No Shareholder shall be


-9-

deemed to have a severable ownership in any individual asset of the Trust or any right of partition or possession thereof.

Section 7. Voting Requirements. In addition to the voting requirements imposed by law or by any other provision of this Declaration of Trust, the provisions set forth in this Article V may not be amended, altered or repealed in any respect, nor may any provision inconsistent with this Article V be adopted, unless such action is approved by the affirmative vote of the holders of at least sixty-six and two-thirds percent (66 2/3%) of the outstanding Common Shares and outstanding Preferred Shares, voting together as a single class. In the event the holders of Common Shares or the holders of Preferred Shares, as the case may be, are required by law or by any other provision of this Declaration of Trust to approve such an action by a class vote of such holders, such action must be approved by the holders of at least sixty-six and two-thirds percent (66 2/3%) of such holders or such lower percentage as may be required by law or by any other provision of this Declaration of Trust.

ARTICLE VI

POWERS OF TRUSTEES

Section 1. Powers. The Trustees in all instances shall have full, absolute and exclusive power, control and authority over the Trust assets and the business and affairs of the Trust to the same extent as if the Trustees were the sole and absolute owners thereof in their own right. The Trustees shall have full power and authority to do any and all acts and to make and execute any and all contracts and instruments that they may consider necessary or appropriate in connection with the management of the Trust.

(n) To set apart, from time to time, out of any funds of the Trust a reserve or reserves for any proper purpose, and to abolish any such reserve;

(o) To consent to or participate in any plan for the reorganization, consolidation or merger of any corporation or issuer, any security or property of which is held in the Trust; to consent to any contract, lease, mortgage, purchase, or sale of property by such corporation or issuer, and to pay calls or subscriptions with respect to any security held in the Trust;

(t) To join with other security holders in acting through a committee, depositary, voting trustee or otherwise, and in that connection to deposit any security with, or transfer any security to, any such committee, depositary or trustee, and to delegate to them such power and authority with relation to any security (whether or not so deposited or transferred) as the Trustees shall deem proper, and to agree to pay, and to pay, such portion of


-12-

the expenses and compensation of such committee, depositary or trustee as the Trustees shall deem proper;

(u) To purchase and pay for out of Trust property such insurance as they may deem necessary or appropriate for the conduct of the business of the Trust, including, without limitation, insurance policies insuring the assets of the Trust and payment of distributions and principal on its portfolio investments, and insurance policies insuring the Shareholders, Trustees, officers, employees, agents, investment advisers or managers, principal underwriters, or independent contractors of the Trust individually against all claims and liabilities of every nature arising by reason of holding, being or having held any such office or position, or by reason of any action alleged to have been taken or omitted by any such person as Shareholder, Trustee, officer, employee, agent, investment adviser or manager, principal underwriter, or independent contractor, whether or not any such action may be determined to constitute negligence, and whether or not the Trust would have the power to indemnify such person against such liability; and

(v) To pay pensions for faithful service, as deemed appropriate by the Trustees, and to adopt, establish and carry out pension, profit-sharing, share bonus, share purchase, savings, thrift and other retirement, incentive and benefit plans, trusts and provisions, including the purchasing of life insurance and annuity contracts as a means of providing such retirement and other benefits, for any or all of the Trustees, officers, employees and agents of the Trust.

Any determination made by or pursuant to the direction of the Trustees in good faith and consistent with the provisions of this Declaration of Trust shall be final and conclusive and shall be binding upon the Trust and every holder at any time of Shares, including, but not limited to the following matters: the amount of the assets, obligations, liabilities and expenses of the Trust; the amount of the net income of the Trust from dividends, capital gains, interest or other sources for any period and the amount of assets at any time legally available for the payment of dividends or distributions; the amount, purpose, time of creation, increase or decrease, alteration or cancellation of any reserves or charges and the propriety thereof (whether or not any obligation or liability for which such reserves or charges were created shall have been paid or discharged); the market value, or any quoted price to be applied in determining the market value, of any security or any other asset owned or held by the Trust; the fair value of any security for which quoted prices are not readily available, or of any other asset owned or held by the Trust; the number of Shares of the Trust issued or issuable; the net asset value per Share; any matter relating to the acquisition, holding and depositing of securities and other assets by the Trust; any question as to


-13-

whether any transaction constitutes a purchase of securities on margin, a short sale of securities, a borrowing, or an underwriting of the sale of, or participation in any underwriting or selling group in connection with the public distribution of, any securities, and any matter relating to the issue, sale, redemption, repurchase, and/or other acquisition or disposition of Shares of the Trust. No provision of this Declaration of Trust shall be effective to protect or purport to protect any Trustee or officer of the Trust against any liability to the Trust or to its security holders 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.

Section 2. Manner of Acting, By-Laws. The By-Laws shall make provision from time to time for the manner in which the Trustees may take action, including, without limitation, at meetings within or without Massachusetts, including meetings held by means of a conference telephone or other communications equipment, or by written consents, the quorum and notice, if any, that shall be required for any meeting or other action, and the delegation of some or all of the power and authority of the Trustees to any one or more committees which they may appoint from their own number, and terminate, from time to time.

ARTICLE VII

EXPENSES OF THE TRUST

The Trustees shall have the power to reimburse themselves from the Trust property for their expenses and disbursements, to pay reasonable compensation to themselves from the Trust property, and to incur and pay out of the Trust property any other expenses which in the opinion of the Trustees are necessary or incidental to carry out any of the purposes of this Declaration of Trust, or to exercise any of the powers of the Trustees hereunder.

ARTICLE VIII

INVESTMENT ADVISER, PRINCIPAL UNDERWRITERS AND
TRANSFER AGE

Section 1. Investment Adviser. The Trust may enter into a written contract with one or more persons (which term shall include any firm corporation, trust or association), hereinafter referred to as the "Investment Adviser", to act as investment adviser to the Trust and as such to perform


-14-

such functions as the Trustees may deem reasonable and proper, including, without limitation, investment advisory, management, research, valuation of assets, clerical and administrative functions. Any such contract shall be subject to the approval of those persons required by the 1940 Act to approve such contract, and shall be terminable at any time upon not more than 60 days' notice by resolution of the Trustees or by vote of a majority of the outstanding voting shares.

Subject to the provisions of Section 4 of this Article VIII, any such contract may be made with any firm or corporation in which any Trustee of the Trust may be interested. The compensation of the Investment Adviser may be based upon a percentage of the net proceeds of the initial public offering of the Shares after payment of underwriting discounts and organization and offering costs, a percentage of the income or gross realized or unrealized gain of the Trust, or a combination thereof, or otherwise, as may be provided in such contract.

Upon the termination of any contract with Nuveen Advisory Corp., or any corporation affiliated with Nuveen Investments, acting as investment adviser or manager, the Trustees are hereby authorized to promptly change the name of the Trust to a name which does not include "Nuveen" or any approximation or abbreviation thereof.

The Trustees may, subject to applicable requirements of the 1940 Act, including those relating to shareholder approval, authorize the investment adviser to employ one or more subadvisers from time to time to perform such of the acts and services of the investment adviser, and upon such terms and conditions, as may be agreed upon between the investment adviser and subadviser.

Section 2. Principal Underwriter. The Trust may enter into a written contract or contracts with an underwriter or underwriters or distributor or distributors whereby the Trust may either agree to sell Shares to the other party or parties to the contract or appoint such other party or parties its sales agent or agents for such Shares. Any such contract may provide that the Trust shall pay such other party or parties such amounts as the Trustees may in their discretion deem reasonable and proper, and may also provide that such other party or parties may enter into selected dealer agreements with registered securities dealers to further the purpose of the distribution of the Shares. Subject to the provisions of Section 4 of this Article VIII, any such contract may be made with any firm or corporation, including, without limitation, the Investment Adviser or an affiliate of the Investment Advisor, or any firm or corporation in which any Trustee of the Trust or the Investment Adviser may be interested.


-15-

Section 3. Transfer Agent. The Trustees may in their discretion from time to time enter into one or more transfer agency and shareholder service contract(s,) whereby the other party shall undertake, to furnish the Trustees with transfer agency and shareholder services. The contract shall be on such terms and conditions as the Trustees may in their discretion determine not inconsistent with the provisions of this Declaration or Trust or of the By-Laws. Such services may be provided by one or more entities.

Section 4. Parties To Contract. Any contract of the character described in Sections 1 and 2 of this Article VIII or in Article X hereof may be entered into with any corporation, firm, partnership, trust or association, including, without limitation, the investment adviser, any investment subadviser or an affiliate of the investment adviser or investment subadviser, although one or more of the Trustees or officers of the Trust may be an officer, director, trustee, shareholder, or member of such other party to the contract, or otherwise interested in such contract and no such contract shall be invalidated or rendered voidable by reason of the existence of any such relationship, nor shall any person holding such relationship be liable merely by reason of such relationship for any loss or expense to the Trust under or by reason of said contract or accountable for any profit realized directly or indirectly therefrom, provided that the contract when entered into was not inconsistent with the provisions of this Article VIII, Article X, or the By-Laws. The same person (including a firm, corporation, partnership, trust or association) may be the other party to contracts entered into pursuant to Sections 1, 2 and 3 above or Article X, and any individual may be financially interested or otherwise affiliated with persons who are parties to any or all of the contracts mentioned in this Section 4.

ARTICLE IX

Section 1. Voting Powers. The Shareholders shall have power to vote only: (a) for the election or removal of Trustees as provided in Article V, (b) with respect to any investment advisory or management contract as provided in Article VIII, Sections 1 and 5, (c) with respect to any termination of the Trust or any series or class thereof to the extent and as provided in Article XIII, Section 1, (d) with respect to any amendment of this Declaration of Trust to the extent and as provided in Article XIII, Section 4, (e) with respect to a merger or consolidation of the Trust or any series or class thereof with any corporation, association, trust or other organization or a reorganization or recapitalization of the Trust or class or series thereof, or a sale, lease or transfer of all or substantially all of the assets of the Trust or any series thereof (other than in the regular course of the Trust's investment activities)


-16-

to the extent and as provided in this Article IX, Section 1, (f) to the same extent as the shareholders of a Massachusetts business corporation as to whether or not a court action, proceeding or claim should be brought or maintained derivatively or as a class action on behalf of the Trust or the shareholders, provided, however that a shareholder of a particular class or series shall not be entitled to bring any derivative or class action on behalf of any other class or series of the Trust, and (g) with respect to such additional matters relating to the Trust as may be required by law, the 1940 Act, this Declaration of Trust, the By-Laws of the Trust, any Statement relating to the issuance of classes or series of shares, or any registration of the Trust with the Commission or any State, or otherwise as the Trustees may consider necessary or desirable.

The affirmative vote of the holders of at least sixty-six and two-thirds percent (66-2/3%) of the outstanding Common Shares and outstanding Preferred Shares, voting as a single class, shall be required to approve, adopt or authorize (i) a conversion of the Trust from a closed-end investment company to an open-end investment company, (ii) a merger or consolidation of the Trust or a series or class of the Trust with any corporation, association, Trust or other organization or a reorganization or recapitalization of the Trust or a series of class of the Trust, (iii) a sale, lease or transfer of all or substantially all of the assets of the Trust (other than in the regular course of the Trust's investment activities), or (iv) a termination of the Trust or a class or a series of the Trust (other than a termination by the Trustees as provided for in Section 1 of Article XIII hereof), unless in each and every case such action has previously been approved, adopted or authorized by the affirmative vote of two-thirds of the total number of Trustees fixed in accordance with this Declaration of Trust or the By-Laws, in which case the affirmative vote of the holders of at least a majority of the outstanding Common Shares and outstanding Preferred Shares, voting as a single class, shall be required, provided however, that where only a particular class or series is effected, only the required vote by the applicable class or series shall be required, and provided further that except as may otherwise be required by law, in the case of the conversion of the Trust from a closed-end investment company to an open-end investment company, or in the case of any of the foregoing transactions constituting a plan or reorganization (as such term is used in the 1940 Act) which adversely affects the Preferred Shares within the meaning of
Section 18(a)(2)(D) of the 1940 Act, approval, adoption or authorization of the action in question will also require the affirmative vote of the holders of sixty-six and two-thirds percent (66-2/3%) of the Preferred Shares 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 this


-17-

Declaration of Trust or the By-Laws. Nothing contained herein shall be construed as requiring approval of Shareholders for any transaction, whether deemed a merger, consolidation, reorganization or otherwise whereby the Trust issues Shares in connection with the acquisition of assets (including those subject to liabilities) from any other investment company or similar entity).

In addition to the voting requirements imposed by law or by any other provision of this Declaration of Trust, the provisions set forth in this Article IX may not be amended, altered or repealed in any respect, nor may any provision inconsistent with this Article IX be adopted, unless such action is approved by the affirmative vote of the holders or at least sixty-six and two-thirds percent (66-2/3%) of the outstanding Common Shares and outstanding Preferred Shares, voting as a single class. In the event the holders of Common Shares or the holders of Shares of Preferred Shares, as the case may be, are required by law to approve such an action by a class vote of such holders, such action must be approved by the, holders of at least sixty-six and two-thirds percent (66 2/3%) of (such holders or such lower percentage as may be required by law. Any series of a class which is adversely affected in a manner different from other series of the same class shall together with any other series of the same class adversely affected in the same manner, be treated as a separate class under this
Section 1.

Section 2. Meetings. Meetings of the Shareholders may be called and held from time to time for the purpose of taking action upon any matter requiring the vote or authority of the Shareholders as herein provided or upon any other matter deemed by the Trustees to be necessary or desirable. Meetings of the Shareholders shall be held at such place within the United States as shall be fixed by the Trustees, and stated in the notice of the meeting. Meetings of the Shareholders may be called by the Trustees and shall be called by the Trustees upon the written request of Shareholders owning at least one-tenth of the outstanding Shares entitled to vote. Shareholders shall be entitled to at least ten days' written notice of any meeting, except where the meeting is an adjourned meeting and the date, time and place of the meeting were announced at the time of the adjournment.

Section 3. Quorum and Action. (a) The Trustees shall set in the By-Laws the quorum required for the transaction of business by the Shareholders at a meeting, which quorum shall in no event be less than thirty percent (30%) of the Shares entitled to vote at such meeting. If a quorum is present when a duly called or held meeting is convened, the Shareholders present may continue to transact business until adjournment, even though the withdrawal of a number of Shareholders originally present


-18-

leaves less than the proportion or number otherwise required for a quorum. Notwithstanding the foregoing, when holders of Preferred Shares are entitled to elect any of the Trustees by class vote of such holders, the holders of 33 1/3% of such Shares entitled to vote at a meeting shall constitute a quorum for the purpose of such an election.

(b) The Shareholders shall take action by the affirmative vote of the holders of a majority, except in the case of the election of Trustees which shall only require a plurality, of the Shares present in person or by proxy and entitled to vote at a meeting of Shareholders at which a quorum is present, except as may be otherwise required by, any provision of this Declaration of Trust, any resolution of the Trustees which authorizes the issuance of Preferred Shares, or the By-Laws.

Section 4. Voting. Each whole Share shall be entitled to one vote as to any matter on which it is entitled to vote and each fractional Share shall be entitled to a proportionate fractional vote, except that Shares held in the treasury of the Trust shall not be voted. There shall be no cumulative voting in the election of Trustees or on any other matter submitted to a vote of the Shareholders. Shares may be voted in person or by proxy. Until Shares are issued, the Trustees may exercise all rights of Shareholders and may take any action required or permitted by law, this Declaration of Trust or the By-Laws of the Trust to be taken by Shareholders.

Section 5. Action by Written Consent in Lieu of Meeting of Shareholders. Any action required or permitted to be taken at a meeting of the Shareholders may be taken without a meeting by written action signed by all of the Shareholders entitled to vote on that action. The written action is effective when it has been signed by all of those Shareholders, unless a different effective time is provided in the written action.

ARTICLE X

CUSTODIAN

All securities and cash of the Trust shall be held by one or more custodians and subcustodians, each meeting the requirements for a custodian contained in the 1940 Act, or shall otherwise be held in accordance with the 1940 Act. The Trustees may also authorize the custodian to employ one or more sub-custodians from time to time to perform such of the acts and services of the custodian, and upon such terms and conditions, as may be agreed upon between the custodian and such sub-custodians, and approved by the Trustees, provided that in every case such sub-custodian shall meet the requirements for a custodian contained in the 1940 Act and the rules and


-19-

regulations thereunder and in any applicable state Securities or blue sky laws.

ARTICLE XI

DISTRIBUTIONS

The Trustees may in their sole discretion from time to time declare and pay such dividends and distributions to shareholders as they may deem necessary or desirable, after providing for actual and accrued expenses and liabilities (including such reserves as the Trustees may establish) determined in accordance with this Declaration of Trust and good accounting practices.

ARTICLE XII

LIMITATION OF LIABILITY AND INDEMNIFICATION

Section 1. Limitation of Liability. No personal liability for any debt or obligation of the Trust shall attach to any Trustee of the Trust. Without limiting the foregoing, a Trustee shall not be responsible for or liable in any event for any neglect or wrongdoing of any officer, agent, employee, investment adviser, subadviser, principal underwriter or custodian of the Trust, nor shall any Trustee be responsible or liable for the act or omission of any other Trustee. Nothing contained herein shall protect any Trustee against any liability to which such Trustee 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.

Every note, bond, contract, instrument, certificate, Share or undertaking and every other act or thing whatsoever executed or done by or on behalf of the Trust or the Trustees or any of them in connection with the Trust shall be conclusively deemed to have been executed or done only in or with respect to their or his capacity as Trustees or Trustee and neither such Trustees or Trustee nor the Shareholders shall be personally liable thereon.

Every note, bond, contract, instrument, certificate or undertaking made or issued by the Trustees or by any officers or officer shall give notice that this Declaration of Trust is on file with the Secretary of State of the Commonwealth of Massachusetts, shall recite that the same was executed or made by or on behalf of the Trust by them as Trustees or Trustee or as officers or officer and not individually and that the obligations of such instrument are not binding upon any of them or the Shareholders individually but are binding only upon the assets and property of the Trust, and may contain such further recitals as they or he may deem appropriate,


-20-

but the omission thereof shall not operate to bind any Trustees or Trustee or officers or officer or Shareholders or Shareholder individually.

All persons extending credit to, contracting with or having any claim against the Trust shall look only to the assets of the Trust for payment under such credit, contract or claim; and neither the Shareholders nor the Trustees, nor any of the Trust's officers, employees or agents, whether past, present or future, shall be personally liable therefor.

Section 2. Trustees' Good Faith Action, Expert Advice, No Bond or Surety. The exercise by the Trustees of their powers and discretions hereunder shall be binding upon everyone interested. A Trustee shall be liable only for his own willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of the office of Trustee, and for nothing else, and shall not be liable for errors of judgment or mistakes of fact or law. The Trustees may take advice of counsel or other experts with respect to the meaning and operation of this Declaration of Trust and their duties as Trustees hereunder, and shall be under no liability for any act or omission in accordance with such advice or for failing to follow such advice. In discharging their duties, the Trustees, when acting in good faith, shall be entitled to rely upon the books of account of the Trust and upon written reports made to the Trustees by any officer appointed by them, any independent public accountant and (with respect to the subject matter of the contract involved) any officer, partner or responsible employee of any other party to any contract entered into hereunder. The Trustees shall not be required to give any bond as such, nor any surety if a bond is required.

Section 3. Liability of Third Persons Dealing with Trustees. No person dealing with the Trustees shall be bound to make any inquiry concerning the validity of any transaction made or to be made by the Trustees or to see to the application of any payments made or property transferred to the Trust or upon its order.

Section 4. Indemnification. 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


-21-

Trustee, director, officer, employee or agent and against amounts paid or incurred by him in settlement thereof.

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


-22-

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 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.

Section 5. Shareholders. No personal liability for any debt or obligation of the Trust shall attach to any Shareholder or former Shareholder of the Trust. In case any Shareholder or former Shareholder of the Trust shall be held to be personally liable solely by reason of his being or having been a Shareholder and not because of his acts or omissions, or for some other reason, the Shareholder or former Shareholder (or his heirs, executors, administrators or other legal representatives or in the case of a corporation or other entity, its corporate or other general successor) shall be entitled out of the assets of the Trust to be held harmless from and indemnified against all loss and expense arising from such liability; provided, however, there shall be no liability or obligation of the Trust arising hereunder to reimburse any Shareholder for taxes paid by reason of such Shareholder's ownership of any Share or for losses suffered by reason of any changes in value of any Trust assets. The Trust shall, upon request by the Shareholder or former Shareholder, assume the defense of any claim made against the Shareholder for any act or obligation of the Trust and satisfy any judgment thereon.


-23-

ARTICLE XIII

MISCELLANEOUS

Section 1. Termination of Trust. (a) Unless terminated as provided herein, the Trust shall continue, without limitation of time. Except as may be set forth in any Statement relating to the issuance of Shares, the Trust, or any class or series thereof may be terminated at any time by the Trustees by written notice to the Shareholders without a vote of the shareholders of the Trust, or the class or series as the case may be, or by the affirmative vote of the shareholders entitled to vote at least sixty-six and two-thirds percent (66 2/3%) of the outstanding Common Shares and Preferred Shares, voting as a single class, in the case of the termination of the Trust, or by the effected class or series as the case may be in the event of the termination of a class or series, unless such action has previously been approved, adopted or authorized by the affirmative vote of two-thirds of the total number of Trustees fixed in accordance with this Declaration of Trust or the By-Laws, in which case the affirmative vote of the holders of at least a majority of the outstanding Common Shares and Preferred Shares, voting as a single class or the applicable class or series as the case may be, shall be required.

Upon termination of the Trust or any series or class thereof, after paying or otherwise providing for all charges, taxes, expenses and liabilities, whether due or accrued or anticipated, as may be determined by the Trustees, the Trust shall, in accordance with such procedures as the Trustees consider appropriate, reduce the remaining assets of the Trust or the applicable series or class to distributable form in cash or other securities, or any combination thereof, and distribute the proceeds to the holders of Preferred Shares in the manner set forth by resolution of the Trustees, and to the holders of Common Shares held by such holders on the date of termination in the event of a termination of the Trust, or to Shareholders of the applicable series or class, as the case may be.

Section 2. Filing of Copies, References, Headings. The original or a copy of this instrument, each amendment hereto and any Statement authorized by Article III, Section 2 hereof shall be kept in the office of the Trust where it may be inspected by any Shareholder. A copy of this Declaration and of each amendment and Statement shall be filed by the Trustees with the Secretary of State of the Commonwealth of Massachusetts, as well as any other governmental office where such filing may from time to time be required, provided, however, that the failure to so file will not invalidate this Declaration or an properly authorized amendment or Statement. Anyone dealing with the Trust may rely on a certificate by an officer or Trustee of the Trust as to whether or not any such amendments


-24-

have been made or Statements authorized and as to any matters in connection with the Trust hereunder, and with the same effect as if it were the original, may rely on a copy certified by an officer or Trustee of the Trust to be a copy of this instrument or of any such amendments or Statements. In this instrument or in any such amendment, references to this instrument, and all expressions like "herein," "hereof" and "hereunder," shall be deemed to refer to this instrument as a whole and as amended or affected by any such amendment. Headings are placed herein for convenience of reference only, and in case of any conflict, the text of this instrument, rather than the headings, shall control. This instrument may be executed in any number of counterparts, each of which shall be deemed an original.

Section 3. Trustees May Resolve Ambiguities. The Trustees may construe any of the provisions of this Declaration insofar as the same may appear to be ambiguous or inconsistent with any other provisions hereof, and any such construction hereof by the Trustees in good faith shall be conclusive as to the meaning to be given to such provisions.

Section 4. Amendments. Except as otherwise specifically provided in this Declaration of Trust, this Declaration of Trust may be amended at any time by vote of a majority of the then Trustees with the consent of shareholders holding more than fifty percent (50%) of Shares entitled to vote. In addition, notwithstanding any other provision to the contrary contained in this Declaration of Trust, the Trustees may amend this Declaration of Trust without the vote or consent of shareholders (i) at any time if the Trustees deem it necessary in order for the Trust or any series or class thereby to meet the requirements of applicable Federal or State laws or regulations, or the requirements of the regulated investment company provisions of the Internal Revenue Code, (ii) change the name of the Trust or to supply any omission, cure any ambiguity or cure, correct or supplement any defective or inconsistent provision contained herein, or (iii) for any reason at any time before a registration statement under the Securities Act of 1933, as amended, covering the initial public offering of Shares has become effective. A certification in recordable form signed by a majority of the Trustees or by the Secretary or any Assistant Secretary of the Trust setting forth such amendment and reciting that it was duly adopted by the shareholders or by the Trustees as aforesaid or a copy of the Declaration, as amended, in recordable form, and executed by a majority of the Trustees or certified by the Secretary or any Assistant Secretary of the Trust, shall be conclusive evidence of such amendment when lodged among the records of the Trust.


-25-

IN WITNESS WHEREOF, the undersigned, being a majority of the Trustees of the Trust, have executed this instrument as of this 29th day of July 2002.

AND
OFFICES

Section 1.1. Declaration of Trust. These By-Laws shall be subject to the Declaration of Trust, as from time to time in effect (the "Declaration of Trust"), of Nuveen Insured Tax-Free Advantage Municipal Fund, the Massachusetts business trust established by the Declaration of Trust (the "Trust").

Section 1.2. Registered Agent. The registered agent of the Trust in the Commonwealth of Massachusetts shall be CT Corporation System, 101 Federal Street, Boston, Massachusetts, or such other agent as may be fixed by the Board of Trustees.

Section 1.3 Other Offices. The Trust may have such other offices and places of business within or without the Commonwealth of Massachusetts as the Board of Trustees shall determine.

ARTICLE II

SHAREHOLDERS

Section 2.1. Place of Meetings. Meetings of the Shareholders may be held at such place or places within or without the Commonwealth of Massachusetts as shall be fixed by the Board of Trustees and stated in the notice of the meeting.

Section 2.2. Regular Meeting. Regular meetings of the Shareholders for the election of Trustees and the transaction of such other business as may properly come before the meeting shall be held on an annual or other less frequent periodic basis at such date and time as the Board of Trustees by resolution shall designate, except as otherwise required by applicable law.

Section 2.3. Special Meeting. Special meetings of the Shareholders for any purpose or purposes may be called by the Chairman of the Board, the President or two or more Trustees, and must be called at the written request stating the purpose or purposes of the meeting, of Shareholders entitled to cast at least l0 percent of all the votes entitled to be cast at the meeting.


-2-

Section 2.4. Notice of Meetings. Notice stating the time and place of the meeting and in the case of a special meeting the purpose or purposes thereof and by whom called, shall be delivered to each Shareholder not less than ten nor more than ninety days prior to the meeting, except where the meeting is an adjourned meeting and the date, time and place of the meeting were announced at the time of the adjournment.

Section 2.5. Quorum and Action. (a) The holders of a majority of the voting power of the shares of beneficial interest of the Trust (the "Shares") entitled to vote at a meeting are a quorum for the transaction of business. If a quorum is present when a duly called or held meeting is convened, the Shareholders present may continue to transact business until adjournment, even though the withdrawal of a number of Shareholders originally present leaves less than the proportion or number otherwise required for a quorum. Notwithstanding the foregoing, when the holders of Preferred Shares are entitled to elect any of the Trust's Trustees by class vote of such holders, the holders of 33 1/3% of the Shares entitled to vote at a meeting shall constitute a quorum for the purpose of such an election.

(b) The Shareholders shall take action by the affirmative vote of the holders of a majority, except in the case of the election of Trustees which shall only require a plurality, of the voting power of the Shares present and entitled to vote at a meeting of Shareholders at which a quorum is present, except as may be otherwise required by the Investment Company Act of 1940, as amended (the "1940 Act"), the Declaration of Trust or any resolution of the Trustees which authorizes the issuance of Preferred Shares.

Section 2.6. Voting. At each meeting of the Shareholders, every, holder of Shares then entitled to vote may vote in person or by proxy and, except as otherwise provided by the 1940 Act, the Declaration of Trust or any resolution of the Trustees which authorizes the issuance of Preferred Shares, shall have one vote for each Share registered in his name.

Section 2.7. Proxy Representation. A Shareholder may cast or authorize the casting of a vote by filing a written appointment of a proxy with an officer of the Trust at or before the meeting at which the appointment is to be effective. The placing of a Shareholder's name on a proxy pursuant to telephonic or electronically transmitted instructions obtained pursuant to procedures which are reasonably designed to verify that such instructions have been authorized by such Shareholder, shall constitute execution of such proxy by or on behalf of such Shareholder. The appointment of a proxy is valid for eleven months, unless a longer period is expressly provided in the appointment. No appointment is irrevocable unless the appointment is coupled with an interest in the Shares or in the Trust.

ARTICLE III

TRUSTEES

Section 3.1. Qualifications and Number: Vacancies. Each Trustee shall be a natural person. A Trustee need not be a Shareholder, a citizen of the United States, or a resident of the Commonwealth of Massachusetts. The number of Trustees of the Trust, their term and election and the filling of vacancies, shall be as provided in the Declaration of Trust.

Section 3.2. Powers. The business and affairs of the Trust shall be managed under the direction of the Board of Trustees. All powers of the Trust may be exercised by or under the authority of the Board of Trustees, except those conferred on or reserved to the Shareholders by statute, the Declaration of Trust or these By-Laws.

Section 3.3. Investment Policies. It shall be the duty of the Board of Trustees to ensure that the purchase, sale, retention and disposal of portfolio securities and the other investment practices of the Trust are at all times consistent with the investment objectives, policies and restrictions with respect to securities investments and otherwise of the Trust filed from time to time with the Securities and Exchange Commission and as required by the 1940 Act, unless such duty is delegated to an investment adviser pursuant to a written contract, as provided in the Declaration of Trust. The Trustees, however, may delegate the duty of management of the assets of the Trust and may delegate such other of their powers and duties to the Executive Committee or any other committee, or to an individual or corporate investment adviser to act as investment adviser or subadviser pursuant to a written contract.

Section 3.4. Meetings. Regular meetings of the Trustees may be held without notice at such times as the Trustees shall fix. Special meetings of the Trustees may be called by the Chairman of the Board or the President, and shall be called at the written request of two or more Trustees. Unless waived by each Trustee, three days' notice of special meetings shall be given to each Trustee in person, by mail, by telephone, or by telegram or cable, or by any other means that reasonably may be expected to provide similar notice. Notice of special meetings need not state the purpose or purposes thereof. Meetings of the Trustees may be held at any place within or outside the Commonwealth


-4-

of Massachusetts. A conference among Trustees by any means of communication through which the Trustees may simultaneously hear each other during the conference constitutes a meeting of the Trustees or of a committee of the Trustees, if the notice requirements have been met (or waived) and if the number of Trustees participating in the conference would be sufficient to constitute a quorum at such meeting. Participation in such meeting by that means constitutes presence in person at the meeting.

Section 3.5. Quorum and Action. A majority of the Trustees currently holding office, or in the case of a meeting of a committee of the Trustees, a majority of the members of such committee, shall constitute a quorum for the transaction of business at any meeting. If a quorum is present when a duly called or held meeting is convened, the Trustees present may continue to transact business until adjournment, even though the withdrawal of a number of Trustees originally present leaves less than the proportion or number otherwise required for a quorum. At any duly held meeting at which a quorum is present, the affirmative vote of the majority of the Trustees present shall be the act of the Trustees or the committee, as the case may be, on any question, except where the act of a greater number is required by these By-Laws or by the Declaration of Trust.

Section 3.6. Action by Written Consent in Lieu of Meetings of Trustees. See Section 6.3 of these By-Laws.

Section 3.7. Committees. The Trustees, by resolution adopted by the affirmative vote of a majority of the Trustees, may designate from their members an Executive Committee, an Audit Committee (whose function shall be to advise the Trustees as to the selection of and review of the work of the independent public accountants of the Trust) and any other committee or committees, each such committee to consist of two or more Trustees and to have such powers and authority (to the extent permitted by law) as may be provided in such resolution. Any such committee may be terminated at any time by the affirmative vote of a majority of the Trustees.

ARTICLE IV

OFFICERS

Section 4.1. Number and Qualifications. The officers of the Trust shall include a Chairman of the Board, a President, a Controller, one or more Vice Presidents (one of whom may be designated Executive Vice President), a Treasurer, and a Secretary. Any two or more offices may be held by the same person. Unless otherwise determined by the Trustees, each officer shall be appointed by the Trustees for a term which shall continue until the meeting of the Trustees following the next regular meeting of Shareholders and until his successor shall have been duly elected and qualified, or until his death, or until he shall have resigned or have been removed, as hereinafter provided in these By-Laws. The Trustees may from time to time elect, or delegate to the Chairman of the Board or the President, or both, the power to appoint, such officers (including one or more Assistant Vice Presidents, one or more Assistant Treasurers and one or more Assistant Secretaries) and such agents as may be necessary or desirable for the business of the Trust. Such


-5-

other officers shall hold office for such terms as may be prescribed by the Trustees or by the appointing authority.

Section 4.2. Resignations. Any officer of the Trust may resign at any time by giving written notice of his resignation to the Trustees, the Chairman of the Board, the President or the Secretary.

Section 4.3. Removal. An officer may be removed at any time, with or without cause, by a resolution approved by the affirmative vote of a majority of the Trustees present at a duly convened meeting of the Trustees.

Section 4.4. Vacancies. A vacancy in any office because of death, resignation, removal, disqualification or any other cause, may be filled for the unexpired portion of the term by the Trustees, or in the manner determined by the Trustees.

In the absence of the Chairman of the Board or in the event of his disability, or inability to act or to continue to act, the President shall perform the duties of the Chairman of the Board and when so acting shall have all the powers of, and be subject to all the restrictions upon, the Chairman of the Board.

Section 4.7. Executive Vice-President. In the case of the absence or inability to act of the President and the Chairman of the Board, the Executive Vice-President shall perform the duties of the President and when so acting shall have all the powers of, and be subject to all the restrictions upon, the President. The Executive Vice-President shall perform all duties incident to the office of Executive Vice-President and such other duties as from time to time may be assigned to him by the Trustees, the President or these By-Laws.

SHARES

Section 5.1. Share Certificates. Each owner of Common Shares of the Trust shall be entitled upon request to have a certificate, in such form as shall be approved by the Trustees, representing the number of Common Shares of the Trust owned by him. Certificates representing fractional Common Shares shall not be issued. The certificates


-8-

representing Common Shares shall be signed in the name of the Trust by the Chairman of the Board, the President, the Executive Vice President or a Vice President and by the Secretary, an Assistant Secretary, the Treasurer or an Assistant Treasurer (which signatures may be either manual or facsimile, engraved or printed). In case any officer who shall have signed such certificate shall have ceased to be such officer before such certificates shall be issued, they may nevertheless be issued by the Trust with the same effect as if such officer were still in office at the date of their issuance. No certificates representing Preferred Shares shall be issued except as the Trustees may otherwise authorize.

Section 5.2. Books and Records; Inspection. The Trust shall keep at its principal executive office, or at another place or places within the United States determined by the Trustees, a share register not more than one year old, containing the names and addresses of the shareholders and the number of Shares held by each Shareholder. The Trust shall also keep, at its principal executive office, or at another place or places within the United States determined by the Trustees, a record of the dates on which certificates representing Shares were issued.

Section 5.3. Share Transfers. Upon compliance with any provisions restricting the transferability of Shares that may be set forth in the Declaration of Trust, these By-Laws, or any resolution or written agreement in respect thereof, transfers of Shares of the Trust shall be made only on the books of the Trust by the registered holder thereof, or by his attorney thereunto authorized by power of attorney duly executed and filed with an officer of the Trust, or with a transfer agent or a registrar and on surrender of any certificate or certificates for such Shares properly endorsed and the payment of all taxes thereon. Except as may be otherwise provided by law or these By-Laws, the person in whose name Shares stand on the books of the Trust shall be deemed the owner thereof for all purposes as regards the Trust; provided that whenever any transfer of Shares shall be made for collateral security, and not absolutely, such fact, if known to an officer of the Trust, shall be so expressed in the entry of transfer.

Section 5.4. Regulations. The Trustees may make such additional rules and regulations, not inconsistent with these By-Laws, as they may deem expedient concerning the issue, certification, transfer and registration of Shares of the Trust. They may appoint, or authorize any officer or officers to appoint, one or more transfer agents or one or more transfer clerks and one or more registrars and may require all certificates for Shares to bear the signature or signatures of any of them.

Section 5.5. Lost, Destroyed or Mutilated Certificates. The holder of any certificate representing Shares of the Trust shall immediately notify the Trust of any loss, destruction or mutilation of such certificate, and the Trust may issue a new certificate in the place of any certificate theretofore issued by it which the owner thereof shall allege to have been lost or destroyed or which shall have been mutilated, and the Trustees may, in their discretion, require such owner or his legal representatives to give to the Trust a bond in such sum, limited or unlimited, and in such form and with such surety or sureties as the


-9-

Trustees in their absolute discretion shall determine, to indemnify the Trust against any claim that may be made against it on account of the alleged loss or destruction of any such certificate, or the issuance of a new certificate. Anything herein to the contrary notwithstanding, the Trustees, in their absolute discretion, may refuse to issue any such new certificate, except as otherwise required by law.

Section 5.6. Record Date; Certification of Beneficial Owner. (a) The Trustees may fix a date not more than ninety (90) days before the date of a meeting of Shareholders as the date for the determination of the holders of Shares entitled to notice of and entitled to vote at the meeting or any adjournment thereof.

(b) The Trustees may fix a date for determining Shareholders entitled to receive payment of any dividend or distribution or allotment of any rights or entitled to exercise any rights in respect of any change, conversion or exchange of Shares.

(c) In the absence of such fixed record date, (i) the date for determination of Shareholders entitled to notice of and entitled to vote at a meeting of Shareholders shall be the later of the close of business on the day on which notice of the meeting is mailed or the thirtieth day before the meeting, and (ii) the date for determining Shareholders entitled to receive payment of any dividend or distribution or an allotment of any rights or entitled to exercise any rights in respect of any change, conversion or exchange of Shares shall be the close of business on the day on which the resolution of the Trustees is adopted.

(c) A resolution approved by the affirmative vote of a majority of the Trustees present may establish a procedure whereby a Shareholder may certify in writing to the Trust that all or a portion of the Shares registered in the name of the Shareholder are held for the account of one or more beneficial owners. Upon receipt by the Trust of the writing, the persons specified as beneficial owners, rather than the actual Shareholders, are deemed the Shareholders for the purposes specified in the writing.

ARTICLE VI

MISCELLANEOUS

(b) Except as otherwise specifically provided herein, all notices required by these By-Laws shall be printed or written, and shall be delivered either personally, by


-10-

telecopy, telegraph or cable, or by mail or courier or delivery service, and, if mailed, shall be deemed to be delivered when deposited in the United States mail, postage prepaid, addressed to the Shareholder or Trustee at his address as it appears on the records of the Trust.

Section 6.3 Action by Written Consent in Lieu of Meeting. (a) An action required or permitted to be taken at a meeting of the Shareholders may be taken without a meeting by written action signed by all of the Shareholders entitled to vote on that action. The written action is effective when it has been signed by all of those Shareholders, unless a different effective time is provided in the written action.

(b) An action which requires Shareholder approval and which is required or permitted to be taken at a meeting of Trustees may be taken by written action signed by all of the Trustees. An action which does not require Shareholder approval and which is required or permitted to be taken at a meeting of the Trustees or a Committee of the Trustees may be taken by written action signed by the number of Trustees that would be required to take the same action at a meeting of the Trustees or Committee, as the case may be, at which all Trustees were present. The written action is effective when signed by the required number of Trustees, unless a different effective time is provided in the written action. When written action is taken by less than all Trustees, all Trustees shall be notified immediately of this text and effective date.

Section 6.4 Reports to Shareholders. The books of account of the Trust shall be examined by an independent firm of public accountants at the close of each annual period of the Trust and at such other times, if any, as may be directed by the Trustees. A report to the Shareholders based upon such examination shall be mailed to each Shareholder of the Trust of record at his address as the same appears on the books of the Trust. Each such report shall show the assets and liabilities of the Trust as of the annual or other period covered by the report and the securities in which the funds of the Trust were then invested; such report shall also show the Trust's income and expenses for the period from the end of the Trust's preceding fiscal year to the close of the annual or other period covered by the report and any other information required by the 1940 Act, and shall set forth such other matters as the Trustees or such independent firm of public accountants shall determine.

Section 6.5 Approval of Firm of Independent Public Accountants. At any regular meeting of the Shareholders of the Trust there may be submitted, for ratification or rejection, the name of the firm of independent public accountants which has been selected for the fiscal year in which such meeting is held by a majority of those members of the Trustees who are not investment advisers of, or affiliated persons of an investment adviser of, or officers or employees of, the Trust, as such terms are defined in the 1940 Act.

Section 6.6 Custodian. All securities and cash of the Trust shall be held by a custodian meeting the requirements for a custodian contained in the 1940 Act and the


-11-

rules and regulations thereunder and in any applicable state securities or blue sky laws. The Trust shall enter into a written contract with the custodian regarding the powers, duties and compensation of the custodian with respect to the cash and securities of the Trust held by the custodian. Said contract and all amendments thereto shall be approved by the Trustees of the Trust. The Trust shall upon the resignation or inability to serve of the custodian obtain a successor custodian and require that the cash and securities owned by the Trust be delivered to the successor custodian.

Section 6.7 Prohibited Transactions. No officer or Trustee of the Trust or of its investment adviser shall deal for or on behalf of the Trust with himself, as principal or agent, or with any corporation or partnership in which he has a financial interest. This prohibition shall not prevent: (a) officers or Trustees of the Trust from having a financial interest in the Trust, its principal underwriter or its investment adviser; (b) the purchase of securities for the portfolio of the Trust or the sale of securities owned by the Trust through a securities dealer, one or more of whose partners, officers or directors is an officer or Trustee of the Trust, provided such transactions are handled in the capacity of broker only and provided commission charged do not exceed customary brokerage charges for such service; (c) the purchase or sale of securities for the portfolio of the Trust pursuant to a rule under the 1940 Act or pursuant to an exemptive order of the Securities and Exchange Commission; or
(d) the employment of legal counsel, registrar, transfer agent, dividend disbursing agent, or custodian having a partner, officer or director who is an officer or Trustee of the Trust, provided only customary fees are charged for services rendered to or for the benefit of the Trust.

Section 6.8 Bonds. The Trustees may require any officer, agent or employee of the Trust to give a bond to the Trust, conditioned upon the faithful discharge of his duties, with one or more sureties and in such amount as may be satisfactory to the Trustee. The Trustees shall, in any event, require the Trust to provide and maintain a bond issued by a reputable fidelity insurance company, authorized to do business in the place where the bond is issued, against larceny and embezzlement, covering each officer and employee of the Trust, who may singly, or jointly with others, have access to securities or funds of the Trust, either directly or through authority to draw upon such funds or to direct generally the disposition of such securities, such bond or bonds to be in such reasonable form and amount as a majority of the Trustees who are not "interested persons" of the Trust as defined in the 1940 Act shall approve not less than once every twelve months, with due consideration to all relevant factors including, but not limited to, the value of the aggregate assets of the Trust to which any such officer or employee may have access, the type and terms of the arrangements made for the custody and safekeeping of such assets, and the nature of the securities in the Trust's portfolio, and as meet all requirements which the Securities and Exchange Commission may prescribe by order, rule or regulation.
